(1)      The amount of Common Stock, par value $0.0001 per share, of American
         Physician Partners, Inc. to be registered hereby is based upon what the
         registrant believes to be a reasonable assumption of the maximum number
         of shares of Common Stock issuable upon consummation of the
         transactions contemplated in this Registration Statement (the "Mergers
         and Exchanges") with Advanced Radiology, P.A. ("Advanced" or "Advanced
         Radiology"), The Ide Group, P.C. ("Ide" or "The Ide Group"), M & S

         Medicine, a Professional Association ("RNM"), Rockland Radiological
         Group and the Valley Radiologists Medical Group, Inc. ("Valley" or

(2)      Estimated solely for the purpose of determining the registration fee
         pursuant to Rule 457(f)(2) of the Securities Act of 1933, as amended
         (the "Securities Act"), based upon the book value of the securities to
         be cancelled or exchanged pursuant to the Mergers and Exchanges,
         calculated as the aggregate of the $16,110,000 book value of such
         securities of Advanced ( as reflected on the Advanced March 31, 1997
         balance sheet), the $2,798,000 book value of such securities of Ide (as
         reflected on the Ide March 31, 1997 balance sheet), the $4,107,000 book
         value of such securities of the M & S X-Ray Practices (as reflected on

         book value of such securities of Pacific Imaging Consultants (as
         reflected on the Pacific Imaging Consultants March 31, 1997 balance
         sheet) the $2,008,000 book value of such securities of RNM (as
         reflected on the RNM March 31, 1997 balance sheet) the $(892,000) book

         $2,039,000 book value of such securities of Valley (as reflected on the
         Valley March 31, 1997 balance sheet). The proposed maximum offering
         price per share is based upon the proposed maximum aggregate offering
         price divided by the number of shares to be registered.

(3)      The registration fee of $8,009 has been calculated pursuant to Rule
         457(f)(2) as follows: 1/33 of one percent of the aggregate book value,
         as of March 31, 1997 of the securities to be cancelled or exchanged
         pursuant to the Mergers and Exchanges.

                            ADVANCED RADIOLOGY, P.A.

                 NOTICE OF SPECIAL MEETING OF SECURITY HOLDERS
                               TO BE HELD [DATE]

To the security holders of
Advanced Radiology, P.A.:

         NOTICE IS HEREBY GIVEN that a special meeting (the "Special Meeting")
of the security holders of Advanced Radiology, P.A. ("Advanced") will be held
on [DATE] at [MEETING LOCATION], commencing at [TIME], local time, for the
following purposes:

         1.      To approve and adopt the Agreement and Plan of Reorganization
and Merger, dated as of June 27, 1997 (the "Advanced Merger Agreement") by and
between American Physician Partners, Inc., a Delaware corporation ("APPI"), and
Advanced and the transactions contemplated by the Advanced Merger Agreement.

         2.      To transact such other business as may properly come before
the Special Meeting or any adjournment thereof.

         Pursuant to the Advanced Merger Agreement, (1) a separate subsidiary of
APPI will merge with and into Advanced and such subsidiary will cease to exist
as a separate entity (the "Advanced Merger") and (2) each outstanding share of
Common Stock of Advanced ("Advanced Common Stock") will be converted into the
right to receive shares of Common Stock of APPI ("APPI Common Stock") and cash.
The exact number of shares of APPI Common Stock and the exact amount of cash
into which each share of Advanced Common Stock will be converted by reason of
the Advanced Merger will not be determined until the closing of the Advanced
Merger.  The number of shares of APPI Common Stock and the amount of cash into
which each share of Advanced Common Stock will be converted will depend on the
price per share (the "Initial Public Offering Price") of APPI Common Stock
received by APPI in connection with the initial underwritten public offering of
APPI Common Stock contemplated by the Registration Statement on Form S-1 filed
with the Securities and Exchange Commission by APPI, before deduction of any
underwriting commissions, discounts or fees relating thereto. At a minimum, each
share of Advanced Common Stock will be converted into [__________] shares of
APPI Common Stock and $[__________] in cash.

         For illustrative purposes only, assuming that (1) the Initial Public
Offering Price of the APPI Common Stock is $15.00 (although there can be no
assurance that it will be so), and (2) that no security holder of Advanced takes
required actions to properly assert dissenters' rights under Maryland state law,
each share of Advanced Common Stock will be converted into [__________] shares
of APPI Common Stock and $[__________] in cash.

         Approval of the Advanced Merger Agreement and the Advanced Merger
requires the affirmative vote of the holders of two-thirds of the shares of
Advanced Common Stock entitled to vote thereon.

         Security holders of Advanced who do not vote in favor of the Advanced
Merger and who comply with other requirements of Sections 3-202 and 3-203 of
the Maryland General Corporation Law will have the right to demand payment for,
and appraisal of, the value of their shares.  See "The Mergers, Exchanges and
Related Transactions -- Dissenters' Rights Regarding the Mergers" in the
accompanying Prospectus/Joint Proxy Statement.

         Only those security holders of record at the close of business on
[RECORD DATE] will be entitled to notice of and to vote at the Special Meeting
or any adjournment thereof.  A list of security holders will be available
commencing [DATE] and may be inspected during normal business hours prior to
the Special Meeting at the offices of Advanced at 7253 Ambassador Road,
Baltimore, Maryland 21244.



                                        By Order of the Board of Directors,


                                        /s/

                               TO BE HELD [DATE]

To the security holders of
The Ide Group, P.C.:

         NOTICE IS HEREBY GIVEN that a special meeting (the "Special Meeting")
of the security holders of The Ide Group, P.C. ("Ide") will be held on [DATE]
at [MEETING LOCATION], commencing at [TIME], local time, for the following
purposes:

         1.      To approve and adopt the Agreement and Plan of Reorganization
and Merger, dated as of June 27, 1997  (the "Ide Merger Agreement") by and
between American Physician Partners, Inc., a Delaware corporation ("APPI"), and
Ide and the transactions contemplated by the Ide Merger Agreement.

         2.      To transact such other business as may properly come before
the Special Meeting or any adjournment thereof.

         Pursuant to the Ide Merger Agreement, (1) Ide will merge with and into
APPI and will cease to exist as a separate entity (the "Ide Merger") and (2)
each outstanding share of Common Stock of Ide ("Ide Common Stock") will be
converted into the right to receive shares of Common Stock of APPI ("APPI Common
Stock") and cash.  The exact number of shares of APPI Common Stock and the exact
amount of cash into which each share of Ide Common Stock will be converted by
reason of the Ide Merger will not be determined until the closing of the Ide
Merger.  The number of shares of APPI Common Stock and the amount of cash into
which each share of Ide Common Stock will be converted will depend on the price
per share (the "Initial Public Offering Price") of APPI Common Stock received by
APPI in connection with the initial underwritten public offering of APPI Common
Stock contemplated by the Registration Statement on Form S-1 filed with the
Securities and Exchange Commission by APPI, before deduction of any underwriting
commissions, discounts or fees relating thereto.  At a minimum, each share of

$4,398.60 in cash.

         For illustrative purposes only, assuming that (i) the Initial Public
Offering Price of the APPI Common Stock is $15.00 (although there can be no
assurance that it will be so), and (ii) that no security holder of Ide takes
required actions to properly assert dissenters' rights under New York state
law, each share of Ide Common Stock will be converted into 942.56 shares of
APPI Common Stock and $4,712.79 in cash.

         The Ide Merger Agreement requires the approval of the holders of
three-quarters of the outstanding shares of Ide Common Stock.

         Security holders of Ide who do not vote in favor of the Ide Merger and
who comply with other requirements of Section 623 of the New York Business
Corporation Law will have the right to demand payment for, and appraisal of,
the value of their shares.  See "Approval of the Mergers, Exchanges and Related
Transactions -- Dissenters' Rights Regarding the Mergers" in the accompanying
Prospectus/Joint Proxy Statement.

         Only those security holders of record at the close of business on
[RECORD DATE] will be entitled to notice of and to vote at the Special Meeting
or any adjournment thereof.  A list of security holders will be available
commencing [DATE] and may be inspected during normal business hours prior to

other fees relating thereto (the "Initial Public Offering Price"), will be
$14.00, (ii) in connection with the Mergers, none of the security holders will
take required actions to properly assert dissenters' rights under applicable
state law and (iii) in connection with the Exchanges, each of the security
holders agrees to exchange his or her partnership interests as contemplated in
each respective Exchange Agreement.  In the event that the Initial Public
Offering Price of the APPI Common Stock is greater than $14.00 per share, the
total cash consideration received by the security holders of each of the
Entities will increase.  In the event that the Initial Public Offering Price of
the APPI Common Stock is less than $14.00 per share, the total number of shares
of APPI Common Stock received by the security holders of each of the Entities
will be increased.  See "The Mergers, Exchanges and Related Transactions --

subject to certain conditions unless waived by APPI, which include, without
limitation, the following:  (i) the representations and warranties of each
Exchange Entity and





                                       10

partner contained in the applicable Exchange Agreement shall be accurate, (ii)
each Exchange Entity and partner shall have performed the covenants required by
the applicable Exchange Agreement, (iii) APPI shall have received a legal
opinion from counsel to each respective Exchange Entity and partner, and (iv)
each of the Mergers and Exchanges shall have closed.

CLOSING OF THE MERGERS AND EXCHANGES AND EFFECTIVE TIME OF THE MERGERS

         The closing of the transactions contemplated by each Merger Agreement
(the "Merger Closing") will occur on the day on which the transactions
contemplated by the Initial Public Offering are consummated (the "Merger
Transactions Closing Date").  Each Merger will become effective (the "Effective
Time") upon the completion of the filing of a properly executed Certificate of
Merger with the appropriate Secretaries of State as required by the applicable
Merger Agreement reflecting such Merger, which filings will be made after
satisfaction of certain conditions set forth in the Merger Agreements.  See
"The Mergers, Exchanges and Related Transactions -- Terms of the Mergers and
Exchanges--Conditions of each Merger Agreement."  The closing of the
transactions contemplated by each Exchange Agreement (the "Exchange Closing")
will occur on the day on which the transactions contemplated by the Initial
Public Offering are consummated (the "Exchange Transactions Closing Date").

TERMINATION

         Each Merger Agreement and Exchange Agreement may be terminated under
certain circumstances, including, without limitation, (i) by mutual written
consent of APPI and the applicable Merger Entity or Exchange Entity and
partners thereof, (ii) by either APPI or the respective Merger or Exchange
Entity if the other party is in breach of any representation, warranty or
covenant contained in the applicable Merger Agreement or Exchange Agreement,
(iii) if, as a result of the conduct of due diligence and regulatory compliance
procedures, APPI deems termination to be advisable or (iv) if the Merger or
Exchange, as the case may be, is not consummated on or before September 30,
1997.

EXPENSES; FEES

         All fees and expenses incurred in connection with the Merger
Agreements and the transactions contemplated thereby and the Exchange
Agreements and the transactions contemplated thereby will be paid by the party
incurring such expenses, whether or not the respective Merger or Exchange is
consummated.

EXCHANGE/ISSUANCE OF STOCK CERTIFICATES IN THE MERGERS AND EXCHANGES

         At or after the Effective Time of each Merger and on the Closing Date
of each Exchange, APPI will make available, and each holder of the Old Shares
(other than those security holders who take required actions to properly assert
their dissenters' rights under the applicable state law) or Old Partnership
Interests will be entitled to receive, upon surrender to APPI of one or more
stock certificates evidencing such Old Shares for cancellation or upon delivery
to APPI of a bill of sale evidencing the transfer of Old Partnership Interests,
certificates evidencing the number of shares of APPI Common Stock into which
such Old Shares are converted in the applicable Merger or for which such Old
Partnership Interests are exchanged in each Exchange.  No fractional shares of
APPI Common Stock will be issued.  Any security holder otherwise entitled to
receive a fractional share of APPI Common Stock upon consummation of a Merger
or Exchange will receive cash, without interest, in lieu thereof in an amount
equal to such holder's proportionate interest in a share of APPI Common Stock
multiplied by the Initial Public Offering Price of APPI Common Stock.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Due to the benefits to be received by certain individuals who are
officers or directors of Advanced, Ide, M&S, South Texas, San Antonio, Pacific,
TMI, RNM, AIOC, CIA, MRIA, Nyack, Pelham, RRG, WIC and Valley in connection
with the Mergers and those who are partners of Lexington, Madison, South Texas
No. 1 and San Antonio No. 2 in connection with the Exchanges, as described
herein, the interests of these individuals may be different from the interests
of security holders of the Entities generally.  Security holders should
consider such persons' interests in the applicable Merger or Exchange in
connection with any such person's recommendation of such Merger or Exchange.

         For a detailed description of such benefits and compensation, see "The
Mergers, Exchanges and Related Transactions--Interests of Certain Persons in
the Mergers and Exchanges."

accomplishment of the RNM Merger.  Dissenting Security Holders have certain
rights of appraisal under Kansas law.  A Dissenting Security Holder must
properly follow the steps specified by Kansas law and take required actions to
assert such Dissenting Security Holder's dissenters' rights.  Dissenting
Security Holders are urged to consult legal counsel with respect to dissenters'
rights under the KGCC.  See "The Mergers, Exchanges and Related Transactions --

GOVERNMENT AND REGULATORY APPROVALS

         Except as otherwise set forth herein, APPI and the Entities are aware
of no governmental or regulatory approvals required for consummation of the
Mergers and Exchanges, other than compliance with the federal securities laws
and applicable laws of the various states.  See "The Mergers, Exchanges and
Related Transactions -- Government and Regulatory Approvals."

CERTAIN INCOME TAX CONSIDERATIONS

         Each Merger and Exchange is intended to qualify as a reorganization
under either Section 351 or Section 368(a) of the Internal Revenue Code.  In
that case, no gain or loss generally should be recognized (except to the extent
that a security holder receives, or is deemed to receive, cash or property
other than APPI Common Stock) by the holders of shares of Advanced Common
Stock, Ide Common Stock, M&S Common Stock, South Texas Common Stock, San
Antonio Common Stock, Pacific Common Stock, TMI Common Stock, RNM Common Stock,
AIOC Common Stock, CIA Common Stock, MRIA Common Stock, Nyack Common Stock,
Pelham Common Stock, RRG Common Stock, WIC Common Stock or Valley Common Stock
or the holders of partnership interests in Lexington, Madison, South Texas No.
1 or San Antonio No. 2 on the exchange of such shares or partnership interests,
as the case may be, for APPI Common Stock.  Haynes and Boone, special counsel
to APPI, will render an opinion that, upon the respective Merger or Exchange
will constitute a tax-free reorganization under either Section 351 or Section
368(a) of the Internal Revenue Code.  However, all security holders and
partners of the Entities are urged to consult their own tax advisors.  See "The
Mergers, Exchanges and Related Transactions -- Certain Income Tax
Considerations."

ACCOUNTING TREATMENT

     SEC Staff Accounting Bulletin No. 48 ("SAB 48") states that when a company
acquires assets from promoters and security holders in exchange for stock just
prior to or at the time of an initial public offering, such assets should be
recorded at the historical cost to any such promoter or security holder.  Each
of the security holders is involved as a promoter of the Mergers or the
Exchanges, as the case may be, and the related Initial Public Offering.
Accordingly, the assets and liabilities to be acquired by APPI or a subsidiary
thereof in the Merger Transactions and the Exchange Transactions will be
recorded on the balance sheet of APPI in the same amounts as reflected in the
balance sheets of the Entities at the Effective Time of the applicable Merger or
Closing Date of the applicable Exchange.  See "The Mergers, Exchanges and
Related Transactions -- Accounting Treatment."

                       SUMMARY HISTORICAL FINANCIAL DATA
                                 (IN THOUSANDS)


     The following summary historical information for APPI and each of the
Founding Affiliated Practices (Advanced Radiology; The Ide Group, M&S X-Ray
Practices, Pacific Imaging Consultants, Radiology and Nuclear Medicine, Rockland
Radiological Group and Valley Radiology Group) has been derived from the
unaudited financial statements.  In the opinion of management, such information
includes all adjustments (consisting of normal recurring adjustments) necessary
for a fair presentation of the information included therein.  APPI was
incorporated in April 1996 and has conducted no significant operations and
generated no revenue to date other than in connection with the Initial Public
Offering and the pending Mergers and Exchanges.  Results for interim periods are
not necessarily indicative of those to be expected for a full fiscal year.  The
selected financial information should be read in conjunction with "Management's
Discussion and Analysis of Financial Condition and Results of Operations" for
APPI and each of the Entities and the audited financial statements of APPI and
each of the Founding Affiliated Practices and notes thereto included elsewhere
in this Prospectus.

                    PRO FORMA COMBINED FINANCIAL INFORMATION

     Upon the completion of the Initial Public Offering and pursuant to the
Merger Transactions and Exchange Transactions, the Company will acquire certain
assets and liabilities of, and enter into Service Agreements with, the Founding
Affiliated Practices.  The following pro forma financial data gives effect to
the Reorganizations, the conversion of the outstanding $3,500,000 principal
balance of Convertible Promissory Notes bearing interest at 6% per annum (the
"Convertible Notes"), the completion of the Initial Public Offering (assuming a
public offering price of $15.00 per share) and the application of the estimated
net proceeds therefrom as if they had occurred as of January 1, 1996 in the case
of the statement of operations data and March 31, 1997 in the case of the
balance sheet data.  However, APPI and the Founding Affiliated Practices were
not under common control or management during any of such periods.  As a result,
this data is not necessarily indicative of the results the Company would have
achieved had these events actually occurred on the dates indicated nor are they
necessarily an indication of the Company's future results.  The following pro
forma financial data should be read in conjunction with the information set
forth under "Use of Proceeds," "American Physician Partners, Inc. Unaudited Pro
Forma Combined Financial Data," and "Selected Financial Data" and in the
historical financial statements of APPI and the Founding Affiliated Practices
included elsewhere herein.

                                  RISK FACTORS

     An investment in the APPI Common Stock being offered pursuant to the
Merger Agreements and Exchange Agreements involves a high degree of risk.  In
addition to the other information contained and incorporated by reference in
this Prospectus/Joint Proxy Statement, prospective investors should consider
carefully the factors listed below before approving and consenting to the
applicable Merger Agreement, Merger and the transactions contemplated thereby
or the applicable Exchange Agreement, Exchange and the transactions
contemplated thereby, as the case may be, or purchasing the APPI Common Stock
offered thereby.

ABSENCE OF COMBINED OPERATING HISTORY; NO PRIOR OPERATING EXPERIENCE

     APPI was incorporated in April 1996, has generated no revenue to date and
has conducted no significant operations other than in connection with the
Initial Public Offering and the pending Mergers and Exchanges.  The Company
will derive a substantial portion of its revenue from service fees it receives
from the Affiliated Practices for managing certain non-medical aspects of their
operations.  The service fees paid to the Company generally will be based on
the revenue of the Affiliated Practices.  The Company's success will depend in
large part on its ability to apply its management experience and implement
practices, systems and marketing plans to enhance the revenue and profitability
of the Affiliated Practices.  To date, the Founding Affiliated Practices have
been operated as independent entities without common management.  Moreover, the
Company has no preexisting relationship with any of the Founding Affiliated
Practices and has not managed any physician groups in the past.  Due to this
lack of prior operating experience, there can be no assurance that the Company
will be able to integrate successfully the assets and personnel of the Founding
Affiliated Practices or to successfully implement its operating strategies with
and profitably provide management and administrative services to the Founding
Affiliated Practices or any other Affiliated Practices.  Although the pro forma
financial results of the Company for the year ended December 31, 1996 and the
three-months ended March 31, 1997 indicate that the Company generated revenue
and income on a pro forma basis, such pro forma financial results cover periods
when the Founding Affiliated Practices and APPI were not under common control
or management and, therefore, may not be indicative of the Company's future
financial or operating results.  There can be no assurance that the Company
will be profitable on a quarterly or annual basis in the future.

DEPENDENCE ON AFFILIATED RADIOLOGISTS; RISK OF TERMINATION OF SERVICE
AGREEMENTS

     The Company's operations are entirely dependent on its continued
affiliation through Service Agreements with the Founding Affiliated Practices
and any other practices with which it may affiliate in the future.  There can
be no assurance that the Founding Affiliated Practices or any such Affiliated
Practices will operate profitably or that the Service Agreements will not be
terminated.  Advanced and Ide are expected to contribute in the aggregate
approximately 50% of the service fees to be paid to the Company by the Founding
Affiliated Practices, based on their historical net patient revenue and
expenses.  While the Service Agreements with the Founding Affiliated Practices
will have terms of 40 years and may be terminated by the Founding Affiliated
Practices only for cause, the termination of any of the Founding Affiliated
Practices' Service Agreements would have a material adverse effect on the
Company.  In addition, following a termination of a Service Agreement, under
certain circumstances, a Founding Affiliated Practice will have the right to
repurchase from the Company the assets used by, and assume the liabilities
associated with, such Founding Affiliated Practice in the conduct of its
radiology practice.  The Company anticipates that, to the extent that it enters
into management relationships with additional practices, the Service Agreements
entered into with such Affiliated Practices will have provisions providing for
the terms, termination and repurchase of assets similar to those contained in
the Service Agreements with the Founding Affiliated Practices.  Any termination
of the Service Agreements with such Affiliated Practices could have a material
adverse effect on the Company's business, financial condition and results of
operations.  See "APPI -- Operation, Management and Business Following the
Mergers and Exchanges -- Service Agreements."

     Each Founding Affiliated Practice will enter into employment agreements
with the key radiologists associated with each such Founding Affiliated
Practice.  The employment agreements generally will be for a term of five
years.  Although the Company, in conjunction with the Founding Affiliated
Practices, will endeavor to extend such contracts, in the event a significant
number of such radiologists terminate their relationships with the Company, the
Company's business could be adversely affected.  The Company anticipates that,
to the extent it enters into Service Agreements with other Affiliated
Practices, similar employment agreements will be entered into between such
Affiliated Practices and the key radiologists associated with their respective
practices; as such, the Company will face similar risks if a significant number
of such radiologists terminate their relationships with the Affiliated
Practices.  Further, if a significant number of radiologists or other medical
service providers become unable or unwilling to continue in their roles, the
Company's business could be adversely affected.  Neither the Company nor the
Founding Affiliated Practices maintains insurance




                                       21
<PAGE>   58
on the lives of any affiliated physician for the benefit of the Company.  See
"APPI -- Operation, Management and Business Following the Mergers and Exchanges
- -- Affiliation Structure."

     The Service Agreements require the Founding Affiliated Practices to enter
into and enforce agreements with the stockholders and full-time radiologists at
each Founding Affiliated Practice (subject to certain exceptions) that include
covenants not to compete with the Company for a period of at least two years
after termination of employment.  See "APPI -- Operation, Management and
Business Following the Mergers and Exchanges -- Service Agreements." The Company
anticipates that Service Agreements that may be entered into with Affiliated
Practices in the future will also contain similar covenants requiring such
Affiliated Practices to restrict the ability of the stockholders and full-time
radiologists at such Affiliated Practices to compete with the Company.  In most
states, a covenant not to compete will be enforced only to the extent it is
necessary to protect a legitimate business interest of the party seeking
enforcement, does not unreasonably restrain the party against whom enforcement
is sought and is not contrary to public interest.  This determination is made
based on all of the facts and circumstances of the specific case at the time
enforcement is sought.  For this reason, it is not possible to predict with
certainty whether a court will enforce such a covenant in a given situation.  In
addition, the Company is not aware of any judicial precedents which have
addressed whether a management company's interest under a management agreement
will be viewed as the type of protectable business interest that would permit it
to enforce such a covenant.  The inability of the Company to enforce such
anti-competition covenants could have a material adverse effect on the Company's
business, financial condition and results of operations.

RELIANCE ON REFERRALS

     The Company is dependent on referrals from third parties to its owned,
operated or managed ICs and to other ICs or hospitals to which the Affiliated
Practices provide professional services.  A substantial portion of these
referrals are made by physicians who have no contractual obligation or economic
incentive to refer patients to those ICs or hospitals.  The Company generates
revenue from fees charged for technical services provided at its owned,
operated or managed ICs and from service fees that it receives from the
Affiliated Practices.  If a sufficiently large number of physicians elected at
any time to discontinue referring patients to the ICs affiliated with the
Company, it would have a material adverse effect on the Company's business,
financial condition and results of operations.  In addition, there is potential
for disruption of relationships in connection with the acquisition or
assumption of control of a particular IC by the Company, and there can be no
assurance that the Company will retain all of the business conducted by that IC
at the time of acquisition or assumption of control by the Company.

     Further, in an effort to control costs, non-governmental health care
payors have implemented cost containment programs which could limit the ability
of physicians to refer patients to the Company's owned, operated or managed
ICs.  For example, persons enrolled in prepaid health care plans, such as
health maintenance organizations ("HMOs"), often are not free to choose where
they obtain diagnostic imaging, interventional radiology or radiation oncology
services.  Rather, the health plan provides these services directly or
contracts with providers and requires its enrollees to obtain such services
only from such providers.  Some insurance companies and self-insured employers
also limit such services to contracted providers.  Such "closed panel" systems
are now common in the managed care environment.  Other systems create an
economic disincentive for referrals to providers outside of the plan's
designated panel of providers.  Although the Company intends to seek managed
care contracts for its owned, operated or managed ICs and the Affiliated
Practices to provide professional and technical radiology services, there can
be no assurance that the Company will be able to compete successfully for
managed care contracts against larger companies with greater resources.

RISKS ASSOCIATED WITH ACQUISITIONS

     The Company's business strategy includes growth through the acquisition of
radiology practice assets, management service organizations ("MSOs"), ICs and
related businesses and entry into and maintenance of agreements to provide
management and administrative services to radiology practices.  There can be no
assurance that the Company will be able to acquire and retain the assets of, or
provide management and administrative services to, additional radiology
practices, MSOs or ICs, profitably provide such services or successfully
integrate such additional relationships.  In addition, there can be no
assurance that the assets of radiology practices acquired in the future, or the
relationships entered into in the future, will be beneficial to the successful
implementation of the Company's overall strategy or that such assets and
relationships will ultimately produce returns that justify their related
investment or implementation by the Company.  See "APPI -- Operation,
Management and Business Following the Mergers and Exchanges -- Business
Strategy."

     The Company's ability to expand its operations is dependent upon factors
such as its ability to (i) identify attractive and willing candidates for
acquisition, (ii) adapt or amend the Company's structure to comply with present
or future federal and state legal requirements affecting the Company's
arrangements with physician practice groups, including state





                                       22
<PAGE>   59
prohibitions on fee-splitting, corporate practice of medicine and referrals to
facilities in which physicians have a financial interest, (iii) obtain
regulatory approvals and certificates of need, where necessary, and comply with
licensing requirements applicable to the Company, the Affiliated Practices and
the physicians associated with the Affiliated Practices, including their
respective facilities, and (iv) expand the Company's infrastructure and
management to accommodate expansion.  See ""APPI -- Operation, Management and
Business Following the Mergers and Exchanges -- Service Agreements. There can be
no assurance that the Company will be able to achieve these objectives or its
planned growth, that the assets of radiology practices, MSOs or ICs will
continue to be available for acquisition by the Company or that the addition of
such assets or management relationships will be profitable.  Further,
acquisitions involve a number of special risks, including possible adverse
effects on the Company's operating results, diversion of management's attention
and resources, failure to retain key acquired personnel, amortization of
acquired intangible assets and risks associated with unanticipated events or
liabilities, some or all of which could have a material adverse effect on the
Company's business, financial condition and results of operations.

     Following consummation of the Mergers and Exchanges, the Company intends
to finance future acquisitions by using shares of the Common Stock for all or a
portion of the consideration to be paid.  In the event that the Common Stock
does not maintain a sufficient valuation, or potential acquisition candidates
are otherwise unwilling to accept Common Stock as part of the consideration for
the sale of the assets of their businesses, the Company may be required to
utilize more of its cash resources in order to pursue its acquisition program.
The Company may also incur indebtedness to fund future acquisitions.  The
Company has obtained a commitment letter for a $100,000,000 credit facility
from GE Capital Corporation, subject to the negotiation of definitive
documentation, due diligence and certain other conditions.  The Company
anticipates that such credit facility will be effective concurrently with the
closing of the Initial Public Offering, although there can be no assurance to
that effect.  The Company's growth could be limited and its existing operations
impaired unless it is able to obtain additional capital through subsequent debt
or equity financings.  There can be no assurance that the Company will be able
to obtain such additional financing or that, if available, such financing will
be on terms acceptable to the Company.  See "APPI -- APPI Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity and Capital Resources." As a result, there can be no assurance that
the Company will be able to implement its acquisition strategy successfully.

     The Company intends to expand both in areas where the Founding Affiliated
Practices currently operate as well as in new markets.  Although the Company
believes that it is in compliance with applicable anti-trust laws, there can be
no assurance that federal or state governmental authorities would not view the
Company as being dominant in a particular market and, therefore, cause the
Company to divest itself of any particular Affiliated Practice or related
assets.  In addition, these laws could prevent acquisitions of practices that
would be integrated into existing Affiliated Practices if such acquisitions
substantially lessen competition or tend to create a monopoly.

GOVERNMENT REGULATION

     Various federal and state laws regulate the relationships between
providers of health care services, physicians and other clinicians.  See "APPI
- -- Operation, Management and Business Following the Mergers and Exchanges --
Government Regulation and Supervision." These laws include the fraud and abuse
provisions of the Social Security Act, which include the "anti-kickback" and
"anti-referral" laws.  The "anti-kickback" laws prohibit the offering, payment,
solicitation or receipt of any direct or indirect remuneration for the referral
of Medicare or Medicaid patients or for the recommendation, leasing, arranging,
purchasing, ordering or providing of Medicare or Medicaid covered services,
items or equipment.  The "anti-referral" laws impose restrictions on
physicians' referrals for designated health services to entities with which
they have financial relationships.  Violations of the "anti-kickback" or
"anti-referral" laws may result in substantial civil or criminal penalties for
individuals or entities, including large civil monetary penalties and exclusion
from participation in the Medicare and Medicaid programs.  Such exclusion, if
applied to the Company's owned, operated or managed ICs, the Affiliated
Practices or physicians affiliated with the Affiliated Practices, could result
in significant loss of reimbursement.  A determination of liability under any
such laws could have a material adverse effect on the Company's business,
financial condition and results of operations.

     Several states, including states in which some of the Founding Affiliated
Practices are located, have adopted laws similar to the "anti- kickback" and
"anti-referral" laws that cover patients in private programs as well as
government programs.  These laws and their interpretations vary from state to
state and are enforced by the courts and regulatory authorities, each with
broad discretion.  A determination of liability under any such laws could have
a material adverse effect on the Company's business, financial condition and
results of operations.

     The laws of many states, including the states in which the Founding
Affiliated Practices are located, also prohibit business corporations, such as
the Company, from exercising control over the medical judgments or decisions of
physicians and from engaging in certain financial arrangements, such as
fee-splitting, with physicians.  These laws and their interpretations vary from
state to state and are enforced by both the courts and regulatory authorities,
each with





                                       23
<PAGE>   60
broad discretion.  The Company's strategy is to acquire certain assets and
assume certain liabilities of, and to enter into Service Agreements with
Affiliated Practices.  Pursuant to the Service Agreements, the Company will
provide management, administrative, technical and non-medical services to the
Affiliated Practices in exchange for a service fee.  The Company's intent is to
neither practice medicine nor exercise control over the medical judgments or
decisions of the Affiliated Practices or their physicians.  Although the Company
believes that it is in compliance with applicable state laws and regulations
relating to the corporate practice of medicine, there can be no assurance that
regulatory authorities or other parties will not assert that the Company is
engaged in the corporate practice of medicine in such states or that the service
fees paid to the Company by the Affiliated Practices pursuant to the Service
Agreements constitute fee-splitting or the corporate practice of medicine.  If
such a claim was successfully asserted, the Company could be subject to civil
and criminal penalties and could be required to restructure or terminate its
contractual arrangements.  Such results or the inability of the Company to
successfully restructure its relationships to comply with such statutes could
have a material adverse effect on the Company's business, financial condition
and results of operations.  See "APPI -- Operation, Management and Business
Following the Mergers and Exchanges -- Service Agreements."

     Although the Company believes that its operations are in compliance with
applicable federal and state laws, neither the Company's current or anticipated
business operations nor the operations of the Founding Affiliated Practices
have been the subject of judicial or regulatory interpretation.  There can be
no assurance that a review of the Company's business by courts or regulatory
authorities will not result in determinations that could adversely affect the
operations of the Company or that the health care regulatory environment will
not change so as to restrict the Company's operations.  In addition, the
regulatory framework of certain jurisdictions may limit the Company's expansion
into, or ability to continue operations within, such jurisdictions if the
Company is unable to modify its operational structure to conform with such
regulatory framework.  Any limitation on the Company's ability to expand could
have a material adverse effect on the Company's business, financial condition
and results of operations.

     The ownership, construction, operation, expansion and acquisition of ICs
are subject to various federal and state laws, regulations and approvals
concerning the licensing of facilities, personnel, certificates of need and
other required certificates for certain types of health care facilities and
major medical equipment.  These laws could limit the Company's ability to
acquire new imaging equipment or expand or replace its equipment at existing
ICs.  No assurances can be given that the required regulatory approvals for any
future acquisitions, expansions or replacements will be granted to the Company,
and the failure to obtain such approvals could materially and adversely affect
the Company's business, financial condition and results of operations.  See
"APPI -- Operation, Management and Business Following the Mergers and Exchanges
- -- Government Regulation and Supervision."

     In addition to existing health care regulations, there have been numerous
initiatives at the federal and state levels for comprehensive reforms affecting
the payment for and availability of health care services.  The Company believes
that such initiatives will continue during the foreseeable future.  Certain
aspects of these reforms as proposed in the past, such as further reductions in
Medicare and Medicaid payments, if adopted, could materially and adversely
affect the Company's business, financial condition and results of operations.

     Federal regulatory and law enforcement authorities have recently increased
enforcement activities with respect to Medicare and Medicaid fraud and abuse
regulations and other reimbursement laws and rules, including laws and
regulations that govern the Company's activities.  There can be no assurance
that the Company's activities will not be investigated, that claims will not be
made against the Company or that these increased enforcement activities will
not directly or indirectly have an adverse effect on the Company's business,
financial condition and results of operations or the market price of the Common
Stock.

     Certain states have enacted statutes or adopted regulations affecting risk
assumption in the health care industry, including statutes and regulations that
subject any physician or physician network engaged in risk-based contracting to
applicable insurance laws and regulations, which may include, among other
things, laws and regulations providing for minimum capital requirements and
other safety and soundness requirements.  The Company believes that it is, and
the Affiliated Practices are, currently in compliance with such insurance laws
and regulations.  However, implementation of additional regulations or
compliance requirements could result in substantial costs to the Company and
the Affiliated Practices.  The inability to enter into capitated or other
risk-sharing arrangements or the cost of complying with certain applicable laws
that would permit expansion of the Company's risk-based contracting activities
could have a material adverse effect on the Company's business, financial
condition and results of operations.

REIMBURSEMENT TRENDS AND COST CONTAINMENT

     The Company's revenue will be derived from service fees paid to the
Company by the Affiliated Practices pursuant to the Service Agreements and
through its ownership, operation and management of ICs.  Substantially all of
the revenue of the Affiliated Practices and such ICs is currently derived from
government sponsored health care programs





                                       24
<PAGE>   61
(principally, Medicare and Medicaid) and private third-party payors.  During
the three month period ended March 31, 1997, approximately 21% of the pro forma
combined revenue of the  Founding Affiliated Practices was derived from
government approved health care programs and approximately 79% of the pro forma
combined revenue of the Founding Affiliated Practices was derived from private
third-party payors.  The health care industry is experiencing a trend toward
cost containment as government and private third-party payors seek to impose
lower reimbursement and utilization rates and negotiate reduced payment
schedules with service providers.  The Company believes that these trends will
continue to result in a reduction from historical levels in per-patient revenue
for its Affiliated Practices and ICs and that the results of operations of the
Affiliated Practices are likely to continue to be affected by lower
reimbursement levels.  See "APPI -- APPI Management's Discussion and Analysis
of Financial Condition and Results of Operations." Further reductions in
payments or other changes in reimbursement for health care services could have
a material adverse effect on the Company's business, financial condition and
results of operations unless the Company is otherwise able to offset such
payment reductions.

     Rates paid by private third-party payors are based on established
physician and hospital charges and are generally higher than Medicare
reimbursement rates.  Any decrease in the relative number of patients covered
by private insurance could have a material adverse effect on the Company's
business, financial condition and results of operations.

     The federal government has implemented, through the Medicare program, a
resource-based relative value scale ("RBRVS") payment methodology for physician
services.  The RBRVS is a fee schedule that, except for certain geographical
and other adjustments, pays similarly situated physicians the same amount for
the same services.  The RBRVS is adjusted each year and is subject to increases
or decreases at the discretion of Congress.  To date, the implementation of the
RBRVS has reduced payment rates for certain of the procedures historically
provided by the Affiliated Practices.  RBRVS-type payment systems have also
been adopted by certain private third-party payors and the Company believes
that it is likely that other private third-party payors will adopt this payment
methodology in the future.  Wider-spread implementation of such programs could
reduce payments by private third-party payors and could indirectly reduce the
Company's operating margins to the extent that the costs of providing
management, administrative, technical and non-medical services related to such
procedures could not be proportionately reduced.  There can be no assurance
that such cost reduction efforts by governmental or private third-party payors
will not have a material adverse effect on the Company's business, financial
condition and results of operations.  See "APPI -- Operation, Management and
Business Following the Mergers and Exchanges -- Government Regulation and
Supervision."

RISKS ASSOCIATED WITH MANAGED CARE CONTRACTS AND CAPITATED FEE ARRANGEMENTS

     During the three month period ended March 31, 1997, approximately 96% of
the pro forma combined revenue of the Founding Affiliated Practices was derived
from payments made on a fee-for-service basis by patients and third-party
payors (including government programs) and approximately 4% of the pro forma
combined revenue of the Founding Affiliated Practices was derived from
capitated arrangements.  Under capitated or other risk-sharing arrangements,
the health care provider typically is paid a pre-determined amount per-patient
per-month from the payor in exchange for providing all necessary covered
services to  patients covered under the arrangement.  Such contracts pass much
of the financial risk of providing care,  including the risk of
over-utilization, from the payor to the provider.  The Company believes that
its success will, in part, be dependent upon the Company's ability to
negotiate, on behalf of the Affiliated Practices and the Company's owned,
operated or managed ICs, contracts with HMOs, employer groups and other
third-party payors pursuant to which services will be provided on a
risk-sharing or capitated basis by some or all of such Affiliated Practices or
ICs.  Entering into additional risk-sharing arrangements could result in
greater predictability of revenue, but greater unpredictability of expenses
and, consequently, profitability.  There can be no assurance that the Company
will be able to negotiate, on behalf of its Affiliated Practices or the
Company's owned, operated or managed ICs, satisfactory arrangements on a
capitated or other risk-sharing basis.  In addition, to the extent that
patients or enrollees covered by such contracts require more frequent or
extensive care than is anticipated, the Company would incur unanticipated costs
not offset by additional revenue, which would reduce  operating margins.  In
the worst case, the revenue derived from such contracts may be insufficient to
cover the costs of the services provided.  Any such reduction or elimination of
earnings could have a material adverse effect on the Company's business,
financial condition and results of operations.

COMPETITION

     The Company is under competitive pressures for the acquisition and
retention of the assets of, and the provision of management and administrative
services to, additional radiology practices, MSOs and ICs.  There are a number
of publicly-traded companies focused on owning or managing ICs.  The Company is
aware of at least two privately-held physician practice management companies
focused on professional and technical radiology services.  Several companies,
both publicly and privately held, that have established operating histories
and, in some instances, greater resources than the Company are pursuing the
acquisition of general and specialty physician practices and the management of
such





                                       25
<PAGE>   62
practices.  Additionally, some hospitals, clinics, health care companies, HMOs
and insurance companies engage in activities similar to those of the Company.
There can be no assurance that the Company will be able to compete effectively
for the acquisition of, or affiliation with, radiology practices, that
additional competitors will not enter the market, that such competition will
not make it more difficult or expensive to acquire the assets of, and provide
management and administrative services to, radiology practices on terms
beneficial to the Company or that competitive pressures will not otherwise
adversely affect the Company.  See "APPI -- Operation, Management and Business
Following the Mergers and Exchanges -- Competition."

     The Affiliated Practices and the Company's owned, operated or managed ICs
compete with numerous local radiology and imaging service providers.  The
Company believes that changes in governmental and private reimbursement
policies and other factors have resulted in increased competition among
providers for the provision of medical services to consumers.  There can be no
assurance that the Affiliated Practices and the Company's owned, operated or
managed ICs will be able to compete effectively in the markets that they serve,
which inability to compete could materially and adversely affect the Company's
business, financial condition and results of operations.

     Further, the Affiliated Practices will compete with other providers for
managed care contracts.  The Company believes that trends toward managed care
have resulted, and will continue to result, in increased competition for such
contracts.  Other radiology practices and MSOs may have more experience than
the Affiliated Practices and the Company in obtaining such contracts.  There
can be no assurance that the Affiliated Practices and the Company will be able
to obtain future business from managed care entities which will allow the
Company to compete effectively in the markets that they serve, which inability
to compete could materially and adversely affect the Company's business,
financial condition and results of operations.

POTENTIAL LIABILITY AND INSURANCE; LEGAL PROCEEDINGS

     The provision of medical services entails an inherent risk of professional
malpractice and other similar claims.  Although the Company does not believe
that any of the services provided by it to the Affiliated Practices pursuant to
the Service Agreements will constitute the practice of medicine, there can be
no assurance that claims, suits or complaints relating to services and products
provided by Affiliated Practices will not be asserted against the Company in
the future.  Additionally, the Company owns, operates and manages ICs, which
exposes the Company to professional liability claims.  The Company maintains
insurance policies with coverages that it believes are appropriate in light of
the risks attendant to its business.  In addition, pursuant to the Service
Agreements, the Affiliated Practices are required to maintain professional
liability insurance.  Nevertheless, there can be no assurance that successful
malpractice or other claims will not be asserted against the Affiliated
Practices or the Company that exceed the scope of coverage or applicable policy
limits or which could otherwise have a material adverse effect on the Company's
business, financial condition and results of operations.

     The availability and cost of professional liability insurance has been
affected by various factors, many of which are beyond the control of the
Company and the Affiliated Practices.  There can be no assurance that adequate
liability insurance will be available to the Company in the future at
acceptable costs or that the future cost of such insurance to the Company and
the Affiliated Practices will not have a material adverse effect on the
Company's business, financial condition and results of operations.  See "APPI
- -- Operation, Management and Business Following the Mergers and Exchanges --
Corporate Liability and Insurance."

     In connection with the Mergers and Exchanges, the Company will assume and
succeed to substantially all of the obligations of each Founding Affiliated
Practice.  Further, in connection with the acquisition of the assets of other
Affiliated Practices in the future, the Company anticipates that it will
typically succeed to some or all of the liabilities of such Affiliated
Practices.  Therefore, claims may be asserted against the Company for events
that occurred prior to the acquisition of the assets of certain of the
Affiliated Practices.

     On May 22, 1997, the state of Texas adopted legislation that permits
injured patients to sue health insurance carriers, health maintenance
organizations and other managed care entities for medical malpractice.  The
statute becomes effective September 1, 1997.  There can be no assurance that
this legislation will not increase the cost of liability insurance to the
Company for services provided in Texas or any other states in which the Company
does business if similar legislation is adopted in those states.

     In connection with the Mergers and Exchanges, the security holders of the
Founding Affiliated Practices have agreed to indemnify the Company for certain
claims.  There can be no assurance that the Company will be able to recover
payment under any such indemnity agreements or that the failure to fully
recover such amounts will not have a material adverse effect on the Company's
business, financial condition or results of operations.

DEPENDENCE ON INFORMATION SYSTEMS

     The current information systems of the Founding Affiliated Practices
consist of disparate, non-integrated accounting, practice management and other
information systems.  In order to facilitate the extensive information
management requirements necessary to effectively manage operations, compete for
managed care contracts and achieve standardization and efficiencies of scale,
the Company intends to create a network infrastructure and deploy two
company-wide information systems.  The design or selection and implementation
of the various components of these systems and the integration throughout the
Company and the Affiliated Practices and subsequent administration will entail
a significant commitment in capital and management resources.  The Company may
experience unanticipated delays, complications and expenses in implementing,
integrating and operating such systems.  Furthermore, such systems may require
modifications, improvements or replacements as the Company expands or if new
technologies become available.  Such modifications, improvements or
replacements may require substantial expenditures and may require interruptions
in operations during periods of implementation.  There can be no assurance that
the Company will be able to implement and operate these information systems
effectively or that these systems will produce the expected benefits.  The
failure to successfully implement and maintain operational and financial
information systems could have a material adverse effect on the Company's
business, financial condition and results of operations.  See "APPI --
Operation, Management and Business Following the Mergers and Exchanges --
Operations and Development -- Information Management."

DEPENDENCE ON KEY PERSONNEL

     The Company is dependent upon the ability and experience of its executive
officers and key personnel for the management of the Company and the
implementation of its business strategy.  The Company currently has employment
contracts with four of its executive officers and a consulting agreement with
one other executive officer.  Because of the difficulty in finding adequate
replacements for such personnel, the loss of the services of any such personnel
or the Company's inability in the future to attract and retain management and
other key personnel could have a material adverse effect on the Company's
business, financial condition and results of operations.  The Company does not
maintain key man insurance for any of its executive officers.  See "APPI --
Management and Executive Compensation -- Employment Agreements;
Covenants-Not-To-Compete."

SHARES ELIGIBLE FOR FUTURE SALE

     The market price of the Common Stock could be adversely affected by the
sale of substantial amounts of Common Stock in the public market following the
Initial Public Offering.  Upon the completion of the Mergers and Exchanges, the
conversion of the Convertible Notes and completion of the Initial Public
Offering, the Company will have outstanding 18,151,625 shares of Common Stock,
assuming an Initial Public Offering price of $15.00 per share.  The 5,000,000
shares of Common Stock to be sold in the Initial Public Offering will be freely
tradable without restriction under the Securities Act, unless acquired by
"affiliates" of the Company, as that term is defined under the Securities Act
or contractually restricted.

     Simultaneously with the closing of the Initial Public Offering, security
holders of the Founding Affiliated Practices will receive, in the aggregate,
10,714,125 shares of Common Stock, assuming an Initial Public Offering Price of
$15.00 per share as a portion of the consideration for their practices, which
shares will have been registered under the Securities Act.  Certain other
stockholders of the Company will hold, in the aggregate, an additional
2,000,000 shares of Common Stock, none of which are being offered by this
Prospectus/Joint Proxy Statement and none of which were acquired in
transactions registered under the Securities Act.  Such unregistered shares may
not be sold except in transactions registered under the Securities Act or
pursuant to an exemption from registration.  The holders of these 12,714,125
shares of Common Stock have entered into agreements with the Company pursuant
to which such holders have agreed not to sell any shares of Common Stock owned
by them at the time of consummation of the Mergers and Exchanges for a period
of 12 months following the Initial Public Offering, and to thereafter limit the
sale of such Common Stock to 25% of such shares upon expiration of such
12-month period following this the Initial Public Offering; up to an additional
25% of such shares upon expiration of the 18-month period following the Initial
Public Offering, and the remaining 50% of such shares upon expiration of a
24-month period following the Initial Public Offering.  Further, each of the
holders of the Convertible Notes have entered into agreements with the Company
pursuant to which each holder has agreed not to sell any portion of the
Convertible Notes or any shares of the Common Stock issued or issuable upon
conversion thereof for a period of 24 months following the date the Convertible
Notes were issued to such holder (which Notes were issued between September 30,
1996 and December 31, 1996).  The Company has agreed with several underwriters
named in the Form S-1 (the "Underwriters") not to waive the restrictive
provisions of those agreements for 180 days after the date of the Form S-1
without the prior written consent of Smith Barney Inc.  Upon expiration of
these agreements, the registered shares of Common Stock will be eligible for
resale in the public market and the unregistered shares of Common Stock, the
Convertible Notes and the shares of Common Stock issued or issuable upon





                                       27
<PAGE>   64
conversion of the Convertible Notes will become eligible for sale in the public
market, subject to the provisions of Rule 144 of the Securities Act.

     In addition, the Company, its officers and directors and all other holders
of Common Stock and securities convertible into or exercisable or exchangeable
for Common Stock have agreed that for a period of 180 days following the
Initial Public Offering they will not, without the prior written consent of
Smith Barney Inc., offer, sell, contract to sell or otherwise dispose of Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock except, in the case of the Company, in certain limited
circumstances.

CONTROL BY EXISTING STOCKHOLDERS

     Following the completion of the Mergers and Exchanges, the conversion of
the Convertible Notes and completion of the Initial Public Offering, members of
the Board of Directors and the executive officers of the Company will own
approximately 13.8%, and the security holders of the Founding Affiliated
Practices will own approximately 59.0%, of the outstanding shares of Common
Stock.  The Company's Amended and Restated Bylaws do not provide for cumulative
voting.  The Company's Amended and Restated Bylaws provide that, following the
consummation of the Initial Public Offering, the Board of Directors must
nominate two physicians licensed to practice medicine from the Affiliated
Practices for election to the Board of Directors at each annual meeting of the
Company's stockholders (three licensed physicians if the size of the Board of
Directors increases to nine).  Although to the knowledge of the Company such
directors and other persons do not have any arrangements or understandings
among themselves with respect to the voting of the shares of Common Stock
beneficially owned by such persons, following the completion of the Initial
Public Offering such persons will be able to control the affairs of the
Company.  See "APPI -- APPI Principal Stockholders."

ANTI-TAKEOVER CONSIDERATIONS

     Certain provisions of the Company's Restated Certificate of Incorporation,
the Company's Amended and Restated Bylaws and Delaware law could discourage
potential acquisition proposals, delay or prevent a change in control of the
Company and, consequently, limit the price that investors might be willing to
pay in the future for shares of the Common Stock.  These provisions include the
inability to remove directors except for cause and the Company's ability to
issue, without further stockholder approval, shares of preferred stock with
rights and privileges senior to the Common Stock.  The Company also is subject
to Section 203 of the Delaware General Corporation Law (the "DGCL") which,
subject to certain exceptions, prohibits a Delaware corporation from engaging
in any of a broad range of business combinations with an "interested
stockholder" for a period of three years following the date that such
stockholder became an interested stockholder.  See "Comparison of Capital Stock
- -- Description of Capital Stock of APPI."

     The Company has entered into employment agreements with four of its
executive officers which contain provisions that require the Company to pay
certain amounts to such employees upon their termination following certain
events including a change of control of the Company.  Such agreements may delay
or prevent a change of control of the Company.  See "APPI -- Management and
Executive Compensation -- Employment Agreements; Covenants-Not-to-Compete."

NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE

     There has been no public market for the Common Stock, and there can be no
assurance that an active public market for the Common Stock will develop or
continue after the Initial Public Offering.  The Initial Public Offering Price
of $14.00 as assumed throughout this Prospectus/Joint Proxy Statement for
purposes of determining the consideration to be received by the security
holders of the Entities pursuant to the Mergers and Exchanges has been assumed
by the Company after discussions with the Underwriters and may not be
indicative of the market price for the Common Stock at or at any time after the
Initial Public Offering.  There can be no assurance that the market price for
the Common Stock will not decline below the initial market price.  From time to
time after the Initial Public Offering, there may be significant volatility in
the market price for the Common Stock.  The trading price of the Common Stock
could be subject to significant fluctuations in response to variations in the
Company's quarterly operating results, general trends in the Company's
industry, regulatory and reimbursement developments, changes in earnings
estimates by securities analysts and other factors affecting the Company's
industry or the securities market as a whole.  Any such fluctuations may
adversely affect the market price of the Common Stock.





                                       28
<PAGE>   65
IMPACT OF SERVICE AGREEMENTS ON PROVIDER COMPENSATION; RESTRICTIONS ON AUTONOMY
OF FOUNDING AFFILIATED PRACTICES

     Upon Consummation of the Mergers and Exchanges, each of the Founding
Affiliated Practices and the Company will have entered into Service Agreements
pursuant to which the Company will provide management, administrative, technical
and non-medical services to each such Founding Affiliated Practice in exchange
for a service fee.  Payment of the service fee to the Company will be an expense
of each Founding Affiliated Practice and as such will reduce the amount of
revenues available for provider compensation and benefits.  See "APPI --
Operation, Management and Business Following the Mergers and Exchanges  --
Service Agreements."

     Further, the Service Agreements provide the Company with the ability to
influence and control a significant portion of the non-medical aspects of the
Founding Affiliated Practices.  Although each Founding Affiliated Practice will
maintain exclusive authority over the medical aspects of its respective
professional radiologic practice, the ability of such Founding Affiliated
Practice and its providers to take certain non-medical business action such as
hiring and firing non-professional personnel, choice of vendors and acquisition
of equipment or facilities in certain cases will be restricted, unless approved
by the Company.  See "APPI -- Operation, Management and Business Following the
Mergers and Exchanges -- Service Agreements."

REQUIREMENT TO PURCHASE ASSETS

     Upon termination of the Service Agreements by the Company for cause, the
Company has certain rights to require the Founding Affiliated Practice to
purchase from the Company and assume all assets and related liabilities and
obligations associated with the professional and technical radiology services
provided by such Founding Affiliated Practice at the time of such termination.
The purchase price for such assets, liabilities and obligations will be the
lesser of fair market value thereof or the return of the consideration received
in the Merger or Exchange, as applicable.  If any Service Agreement is
terminated by the Company for cause and the Company elects to require the
Founding Affiliated Practice to purchase such assets, liabilities and
obligations, such required purchase could severely impact the cash flows and
financial condition of such Funding Affiliated Practice.  See "APPI --
Operation, Management and Business Following the Mergers and Exchanges --
Service Agreements."

INCOME TAX RISKS

     It is a condition to the closing obligations of APPI and the Entities that
such parties receive an opinion from Haynes and Boone to the effect that the
Mergers and Exchanges will satisfy the requirements for tax deferral under
either Section 351 or Section 368 of the Internal Revenue Code.  No ruling will
be requested from the Internal Revenue Service (the "IRS") on this issue.  An
opinion of counsel is not binding on the IRS or the courts.  Furthermore, no
assurance can be given that the tax-deferred characterization of the Mergers and
Exchanges will not be challenged, or if challenged, will be defended
successfully.  If the tax characterization of the Mergers and Exchanges is
successfully challenged, there could be significant adverse tax consequences to
the Entities and their respective security holders.  In addition, the
Reorganizations may be treated as taxable distributions, with the effect of the
creation of taxable income at both the Company and the security holder levels.
If the value of capital stock of one or more of the NewCos distributed in the
respective Reorganizations exceeds the nominal value determined to be applicable
by the respective boards of directors of the Entities, there could be
significant adverse tax consequences to the Entities distributing, and security
holders receiving, the capital stock of such NewCo or NewCos. See "The Mergers,
Exchanges and Related Transactions -- Certain Income Tax Considerations."

RISKS RELATING TO FAILURE TO APPROVE THE MERGERS, EXCHANGES AND REORGANIZATIONS

     Each of the Entities have incurred and are expected to further incur
substantial costs  in connection with the analysis, planning, documentation,
negotiation and approval process related to the Mergers, Exchanges and
Reorganizations.  In the event the security holders of the Entities do not
approve the proposed Mergers, Exchanges and Reorganizations, there can be no
assurance that the Entities or their respective security holders will have
sufficient funds available to pay such costs and expenses.

     Another risk of failure to approve the Mergers and Exchanges is that the
Entities would remain in their current respective circumstances, which include
the circumstances that led the respective board of directors of each Merger
Entity to recommend the Mergers. See "The Mergers, Exchanges and Related
Transactions -- APPI's Reasons for the Mergers and Exchanges," "-- Advanced
Radiology's Reasons for the Advanced Merger," "-- The Ide Group's Reasons for
the Ide Merger," "-- Pacific Imaging Consultants' Reasons for the Pacific and
TMI Mergers," "-- Radiology and Nuclear Medicine's Reasons for the RNM Merger,"
"-- Rockland Radiological Groups Reasons for the AIOC, CIA, MRIA, Nyack,
Pelham, RRG and WIC Mergers," and "-- Valley Radiology Group's Reasons for the
Valley Merger."

MATERIAL CONTACTS AND BOARD DELIBERATIONS

     APPI was formed in April 1996 to begin operations as a radiology physician
practice management company.  APPI's focus is to develop, consolidate and
manage integrated radiology and IC networks.  APPI's focus was developed based
on the belief of its founders that radiology services in the United States are
delivered through a fragmented system of local providers, including small to
medium-sized groups of diagnostic and interventional radiologists and radiation
oncologists.  In addition, the founders observed that cost-containment
pressures on health care providers, including radiologists, have placed small
to medium-sized physician groups at a competitive disadvantage, since their
practices typically have high operating costs and often lack the capital,
information systems and management expertise necessary to provide both
high-quality and cost-effective medical care.  Following its inception, APPI
began identifying radiology practices that were seeking to affiliate with a
physician practice management company like APPI to perform the non-medical
aspects of their practices and provide access to greater capital resources,
more efficient cost structures and more favorable relationships with payors.

     During May, June and July 1996, APPI developed a list of potential
radiology practices in different parts of the United States that APPI wanted to
approach regarding possible affiliation with APPI.  During this period, APPI
commenced discussions with radiology groups on its target list and entered into
confidentiality agreements with Advanced Radiology and The Ide Group.

     During August, September and October 1996, APPI continued its development
efforts and entered into confidentiality agreements with M&S, RNM and RRG.  In
addition, during this period APPI entered into letters of





                                       51
<PAGE>   88
intent with Advanced, Ide and M&S.  Following the execution of the letters of
intent, APPI commenced financial audits of Advanced, Ide and M&S and also
commenced its legal due diligence with respect to those practices.

     During November and December 1996 and January 1997, APPI continued its
development efforts with practices that had executed confidentiality agreements
with APPI.  APPI entered into letters of intent with RRG and RNM.  Following the
execution of these letters of intent, APPI commenced financial audits of those
practices and legal due diligence.  Also during this period, APPI distributed
its first draft of the Service Agreement to the Founding Affiliated Practices
under letters of intent and to Pacific as Pacific was contemplating whether to
enter into a letter of intent with APPI.  APPI then began preliminary
discussions and negotiations with such Founding Affiliated Practices regarding
the Service Agreement.  During this period, Pacific and Valley entered into
letters of intent with APPI.

     During February, March and April 1997, APPI completed its selection of the
Founding Affiliated Practices following the execution by Pacific and Valley of
letters of intent with APPI.  APPI also commenced financial audits of these
practices and legal due diligence.  APPI and the Founding Affiliated Practices
continued their discussions and negotiation of the Service Agreement.  In
addition, APPI distributed the first draft of the Merger and Exchange
Agreements for review and comment by the Founding Affiliated Practices.

     Thereafter, APPI began negotiations and discussions with the Founding
Affiliated Practices regarding the Merger and Exchange Agreements.  Certain
representatives of the Founding Affiliated Practices met with members of APPI's
management team in Dallas on March 7 and 8 of this year to discuss open issues
in the Service Agreement and the Merger and Exchange Agreements and to plan
strategies for APPI's growth and development.  On April 16 and 17 of this year,
lawyers and certain representatives of the Founding Affiliated Practices met in
Dallas to continue their discussions of open points in the Merger and Exchange
Agreements and the Service Agreement.

     Also during March and April 1997, APPI selected the underwriters for its
proposed Initial Public Offering.  In early April, APPI's management team met
with the underwriters to commence preparation of the Form S-1.  During this
time, APPI continued its legal due diligence and financial audits regarding the
Founding Affiliated Practices.

     During May, June and through the date of this filing, APPI concluded its
negotiation of the Service Agreement, Merger and Exchange Agreements and related
agreements for the Reorganizations and in June such agreements were executed by
APPI and each respective Founding Affiliated Practice.  APPI continued to work
on the Form S-1 and filed the Form S-1 with the SEC on June 27, 1997.  During
this time period, APPI commenced work on this Registration Statement.
Additionally, following the execution of the Merger and Exchange Agreements,
APPI began working with the Founding Affiliated Practices on matters that are
required to be completed or resolved prior to closing such Merger and Exchange
transactions.

APPI'S REASONS FOR THE MERGERS AND EXCHANGES

     APPI was formed in April 1996 for the sole purpose of acquiring and
consolidating radiology practices on a national basis with the explicit purpose
of forming a publicly traded radiology practice management company.  From its
inception, APPI's focus has been to develop, consolidate and manage integrated
radiology and IC networks.  APPI and the Founding Affiliated Practices
recognized that market forces were driving physicians, including radiologists,
into larger group practices and driving group practices to seek corporate
partners to provide management expertise, capital and sophisticated information
systems.  APPI and the Founding Affiliated Practices identified certain factors
which they believe apply pressure to physician groups, which factors include,
without limitation, increased managed care penetration, declining reimbursements
from private and governmental payors, increased competition for payor contracts,
physician oversupply, physician income erosion, increased complexity of billing
and collection processes, increased information system requirements and the need
for greater sums of capital to remain competitive.

     APPI and the Founding Affiliated Practices believed that if APPI could
provide the resources (including business and management expertise, purchasing
power and sophisticated information systems) necessary for radiology practices
to compete in the managed care dominated environment, then radiology practices
would be motivated to affiliate with APPI.  APPI and the Founding Affiliated
Practices believe that if APPI was successful in affiliating with a select
group of radiology practices across the United States, that they would be able
to develop integrated networks of radiology groups and ICs to provide wide
geographic coverage and subspecialty expertise.

     APPI's strategy is to (i) emphasize quality service, (ii) expand within
its selected markets, (iii) improve operating efficiencies within the Founding
Affiliated Practices and (iv) expand into new regional markets through
acquisitions of or affiliations with additional radiology practices and ICs.
APPI believes that the Founding Affiliated Practices form the foundation upon
which APPI can attempt to implement its strategy.

ADVANCED RADIOLOGY'S REASONS FOR THE ADVANCED MERGER

     In considering the Merger, the security holders of Advanced recognized the
need to adapt to many of the changes affecting the practice of medicine and the
business of providing medical services.  The security holders of Advanced
believe that for the following reasons the Advanced Merger will be beneficial to
Advanced:

     .    Increased capital funding to acquire and upgrade equipment and acquire
          new sites

     .    Economies of scale through increased purchasing power

     .    Combining with the other Founding Affiliated Practices would enable
          Advanced to acquire additional practice sites and practice groups

     .    Increase in effectiveness in obtaining third-party payor contracts

     .    The availability of cost effective management, medical records,
          billing and similar efficiencies of the practice

     The Board of Directors of Advanced weighed the benefits of joining with
APPI and concluded that APPI would allow it, and the other Founding Affiliated
Practices, to further achieve those objectives which originally prompted the
formation of Advanced.  These included (i) providing greater access to making
available capital funding; (ii) allowing Advanced to directly share in the
economic benefits of the technical component of its practice, including the
additional facilities made available through such capital funding; (iii)
providing a larger purchasing pool; (iv) providing cost effective management
expertise; (iv) expanding the efficiencies of office and billing functions; and
(v) maintaining strong physician leadership.

ADVANCED BOARD'S RECOMMENDATION

     The Advanced Board believes that the Advanced Merger and the terms of the
Advanced Merger Agreement are fair to, and in the best interests of, Advanced
and its security holders and has thus approved the Advanced Merger Proposal.
THE ADVANCED BOARD RECOMMENDS THAT ADVANCED SECURITY HOLDERS VOTE IN FAVOR OF
THE ADVANCED MERGER PROPOSAL.

THE IDE GROUP'S REASONS FOR THE IDE MERGER

     The Board of Directors of Ide recognized that significant changes will take
place over the next few years in the area of health care reimbursement for the
country as a whole and the Rochester, New York area in particular.  The Board of
Directors of Ide believes that for the following reasons the Ide Merger will be
beneficial to Ide:

     .    Increased capital, which could no longer be obtained from either
          retained earnings or borrowings, would be needed to sustain the
          continued growth of the existing operation and enable Ide to consider
          the possibility of new facilities.  In addition, Ide anticipates
          significantly expanded capital requirements as it moves toward
          outsourcing entire hospital radiology departments.

     .    While Ide has seen substantial growth over the past 20 years with the
          current physician leadership, to insure the continued longevity of
          the practice, it became apparent that the practice would need the
          expertise that can only be obtained from physician leadership with a
          national core of experience.

     .    While Ide has been the primary and largest radiology practice in the
          Western New York area, to insure the continuation of this status
          requires the ability to attract and develop new professional
          opportunities while continuing to serve existing relationships.
          Given the potential changes in reimbursement and the potential
          affiliation of Ide's competitors in the Rochester area, a significant
          marketing campaign would need to be undertaken to continue the path
          chosen by the Ide Board.  This effort can only be accomplished with
          the following:

               (i)  A national organization with the expertise to assist the
          physicians in negotiating third party payor contracts.

               (ii) The ability to deliver "state of the art" professional and
          technical service in the fields of radiology and radiation oncology.

               (iii) The ability to assist the physicians in the ongoing
          marketing of the practice in order to maintain existing relationships
          and develop new opportunities.

IDE BOARD'S RECOMMENDATION

     The Ide Board believes that the Ide Merger and the terms of the Ide Merger
Agreement are fair to, and in the best interests of, Ide and its security
holders and has thus approved the Ide Merger Proposal.  THE IDE BOARD RECOMMENDS
THAT IDE SECURITY HOLDERS VOTE IN FAVOR OF THE IDE MERGER PROPOSAL.

M&S X-RAY PRACTICES' REASONS FOR THE M&S, SOUTH TEXAS AND SAN ANTONIO MERGERS
AND THE MADISON, LEXINGTON, SOUTH TEXAS NO. 1 AND SAN ANTONIO NO. 2 EXCHANGES

     An association of three radiologists in the late 1960's evolved into the
current radiology practice known as M&S X-Ray Associates, P.A.  During this
time, additional growth opportunities were pursued and by the mid 1990's M&S
X-Ray Associates grew to its current complement of twenty radiologists.  Its
affiliated corporate and joint venture entities comprise a radiology delivery
system comprised of five hospital professional service contracts and seven
outpatient imaging centers.  Concurrent with this growth and development, the
health care delivery system within the San Antonio, Texas Metropolitan area was
undergoing a transformation not unlike that being experienced by other major
metropolitan areas in the country.  Significant trends in the practice of
radiology included:

     .    The impact of managed care and the related decrease in reimbursement
          from third party payors.

     .    The development of medical practice groups that were beginning to
          merge and form affiliations, both within radiology and within the
          general medical community.

     .    Technological advancements within radiology that were demanding more
          sophisticated equipment with increased risk and cost to the
          individuals and corporations investing in new modalities.

     The Board of Directors of M&S recognized the need to increase the business
operations, i.e., production, to offset the decreasing revenues.  M&S, similar
to other practices, sought assistance from consultants to evaluate and
determine how best to respond to the changing environment, while trying to
preserve corporate revenues.  From numerous Board discussions, consultants
reports and other input, a number of conclusions were reached including:

     .    The status quo will not be maintained.  The market will undoubtedly
          force changes in the way radiology is practiced.

     .    Managed care will drive radiology services in the community to embark
          upon significant change including mergers, acquisitions and
          associations that would create what would previously be regarded as
          unlikely alliances.

     .    Health services will be increasingly centered in non-traditional
          hospital/medical center facilities.  Product carve-outs inclusive of
          radiology services will increase in number and scope.

     .    Imaging centers must be developed that are strategically located,
          offering full modality options, be accessible, and provide value
          added services to compete in the emerging market.  This must be
          accomplished while preserving quality and measuring outcomes.

     .    Increased managed care will create an over-supply of radiologists in
          the marketplace.

     .    M&S will not be able to generate needed capital from retained
          earnings to provide for equipment and managerial support systems, to
          preserve revenues and respond to business opportunities.

     Given these conclusions, the Board of Directors of M&S determined that an
affiliation with a national organization that could assist in meeting the
realities of the dynamic environment was desirable.

     What began as informal discussions with APPI developed into in-depth
analysis and a recognition that the respective corporate cultures and goals
were in concert and could lead to an affiliation that would be mutually
beneficial.  It was envisioned that M&S, with APPI, could retain its place of
prominence and secure the necessary market share.  It is believed that the
affiliation with APPI will:

     .    Provide the capital resources necessary to appropriately develop new
          alliances and imaging centers as well as enhance existing operations.





                                       54
<PAGE>   91
     -    Provide improved operating efficiency through economies of scale that
          could be realized by the affiliation economies of scale to be
          achieved in purchasing of routine support supplies for the imaging
          centers, as well as major acquisitions of equipment to maintain a
          competitive technological edge.

     -    Through the input APPI's managerial expertise provide:

          (i)    Strategic planning enhancements to identify opportunities for
                 expansion into new markets

          (ii)   Additional contracting and reimbursement expertise

          (iii)  Marketing support

          (iv)   The acquisition of appropriate information systems to support
                 such operations

     For these reasons the Board deemed it to be prudent, appropriate and
timely that M&S embark upon this affiliation with the belief and commitment
that it will allow M&S to be in a position to quickly respond to opportunities
and thus emerge as the dominate radiological practice in San Antonio, Texas.
By so doing, the existing practice of M&S can be preserved while allowing for
growth and the preservation and increase of related revenues.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF EACH OF M&S, SOUTH TEXAS AND
SAN ANTONIO

     The Board of Directors of each of M&S, South Texas and San Antonio believes
that the M&S Merger, the South Texas Merger and the San Antonio Merger,
respectively, and the terms of the applicable Merger Agreement are fair to, and
in the best interests of, M&S, South Texas and San Antonio, respectively, and
each of their respective security holders and each such Board has thus approved
the M&S Merger Proposal, the South Texas Merger Proposal and the San Antonio
Merger Proposal, respectively.  THE BOARD OF EACH OF M&S, SOUTH TEXAS AND SAN
ANTONIO RECOMMENDS THAT EACH SUCH ENTITY'S RESPECTIVE SECURITY HOLDERS VOTE IN
FAVOR OF THE RESPECTIVE MERGER PROPOSAL.

PACIFIC IMAGING CONSULTANTS' REASONS FOR THE PACIFIC AND TMI MERGERS

     In anticipation of changes in the business of medicine, Pacific began
focusing on growth through acquisitions of other radiology groups beginning in
1986.  In 1989, the security holders of Pacific organized TMI to own and/or
lease the substantial equipment required to operate multiple diagnostic ICs.
However, despite the wide geographic coverage, large numbers of providers and
long-standing managed care experience of Pacific in the San Francisco Bay area,
Pacific's Board recognized the following business conditions:

     -    Capital Needs:  Increased capital, which could no longer be obtained
          from retained earnings, would be needed to sustain continued growth
          and build increasingly necessary and capital-intensive
          infrastructure, including the technological infrastructure necessary
          to improve computer capabilities, network multiple Pacific sites and
          make a the transition to electronic medical record systems; and
          various sources of capital, including debt, venture capital and
          existing physician practice management companies ("PPMs") would not
          adequately meet the needs of Pacific for capital while maintaining
          physician control.

     -    Physician Leadership:  Physicians, especially those in practice
          groups, were in a better position than non-physician business people
          to guide the direction of changes in medicine and to control costs
          because of their unique role as advocates for patients.

     -    Competition:  Competitors in Pacific's market were beginning to
          affiliate with PPMs, hospitals and other third parties, giving them
          better access to capital; and competition for managed care lives was
          increasing in the Northern California market.

     In response to these business conditions, in 1996 Pacific's and TMI's
Boards began exploring the possibility of merging with APPI.  After a number of
meetings with representatives of APPI, Pacific's and TMI's Boards concluded that
there was a strategic fit with APPI based on the following criteria which
Pacific and TMI had established as essential for selecting a capital partner:
significant physician ownership, physician-controlled governance, national group
practice experience and culture, extensive managed care experience and the
ability to exert local market leverage.  Based on additional meetings with APPI
representatives and upon the criteria established, Pacific's and TMI's Boards
determined that the Merger was the preferred option for a strategic and capital
partnership. Accordingly, Pacific's Board and management decided to enter into
discussions with APPI for a possible affiliation among Pacific, TMI and APPI.





                                       55
<PAGE>   92
     The material favorable, unfavorable and certain neutral factors considered
by Pacific's Board in reaching its decision to approve the Merger Proposal
included: synergies, capital needs, access to capital, physician leadership,
employee benefits, fair value and favorable tax consequences.

     In light of these factors, Pacific's and TMI's Boards concluded that the
Merger was fair to, and in the best interests of, Pacific, TMI and their
security holders.  Pacific's and TMI's Boards found that the potential negative
effects of the Merger were outweighed by the positive factors and, thus, that
such positive factors were persuasive in recommending approval of the Pacific 
Merger Proposal and the TMI Merger Proposal to the security holders of Pacific 
and TMI.

RECOMMENDATIONS OF THE BOARDS OF PACIFIC AND TMI

     The Board of each of Pacific and TMI believes that the Pacific Merger and
the terms of the Pacific Merger Agreement and the TMI Merger and the terms of
the TMI Merger Agreement, respectively, are fair to, and in the best interests
of, Pacific and TMI, respectively, and each of their respective security
holders and has thus unanimously approved the Pacific Merger Proposal and the
TMI Merger Proposal, respectively.  THE BOARD OF EACH OF PACIFIC AND TMI
UNANIMOUSLY RECOMMENDS THAT EACH SUCH ENTITY'S RESPECTIVE SECURITY HOLDERS VOTE
IN FAVOR OF THE RESPECTIVE MERGER PROPOSAL.

RADIOLOGY AND NUCLEAR MEDICINE'S REASONS FOR THE RNM MERGER

     In light of anticipated changes in medical technology, reimbursement
methodologies and health care delivery systems in general, RNM believes that
the RNM Merger will provide RNM with the necessary resources to succeed in the
anticipated new health care environment.

     The Board of Directors of RNM believe that the RNM Merger will allow RNM to
realize cost and operating efficiencies, including cost savings which are
anticipated to result from pooled purchasing power for supplies and equipment.
RNM will benefit from the comparison of RNM practice results against the results
achieved by the other Merger Entities, which will create a basis for
streamlining operations of RNM.  Through these increased economic efficiencies,
RNM believes that its physicians will be able to realize the true economic value
of their practice and still retain a degree of autonomy through an
organizational structure allowing for significant input into management. In
addition, RNM will benefit from increased access to capital following the RNM
Merger.

     As a result of the RNM Merger, RNM believes that it will be able to expand
its geographic area of service and will receive necessary assistance in
developing strategic, marketing and business development plans and in
responding to change implemented by private and public payors.

RNM BOARD'S RECOMMENDATIONS

ROCKLAND RADIOLOGICAL GROUP'S REASONS FOR THE AIOC, CIA, MRIA, NYACK, PELHAM,
RRG AND WIC MERGERS

     The Board of Directors of each of AIOC, CIA, MRIA, Nyack, Pelham, RRG and
WIC recognized the need to adapt to many of the changes that were affecting the
practice of medicine and the business of providing medical services.  These
seven entities function in an affiliated manner.  Their affiliation was
prompted for a variety of reasons, including, but not limited to:

     .    The need for the increased capital funding to acquire and upgrade
          equipment and information systems at their current practice sites

     .    To open new practice sites

     .    To maintain and update the data bases required to manage their
          organization

     .    The economies of scale obtained by pooling the purchasing of
          equipment, supplies and services

     .    The need to provide cost effective management





                                       56
<PAGE>   93
      .    The need to increase competitiveness in obtaining third party payor
           contracts

     As a result of their affiliation, such entities continued to recognize that
many of the needs prompting their affiliation continued to exist even though the
affiliation had enabled them to achieve many of their original objectives. When
the Rockland Radiological Group was approached by APPI, the stockholders of such
entities believed that affiliates with a larger entity operating on a national
scope would assist in achieving their objectives.

     Following deliberations regarding the positive and negative aspects of the
affiliation with APPI, each of the entities voted in favor of the Merger.  The
Board of Directors of each of the entities concluded that APPI would allow it
and the other Founding Affiliated Practices to further achieve their objectives,
including:

     .    Making available capital funding

     .    Allowing the groups to directly share in the economic benefit of the
          technical component of their practices, including, the additional
          facilities made available through such capital funding

     .    Providing a larger purchasing pool

     .    Providing cost effective management expertise

     .    Expanding the efficiencies of office and billing functions

     .    Increase competitiveness in obtaining third party payor contracts

     .    Potential to outsource hospital radiology departments using capital
          management experience available through APPI

     .    Maintaining strong leadership as a result of the affiliation with APPI

RECOMMENDATIONS OF THE BOARDS OF AIOC, CIA, MRIA, NYACK, PELHAM, RRG AND WIC

     The Board of each of AIOC, CIA, MRIA, Nyack, Pelham, RRG and WIC believes
that the Merger and the terms of the Merger Agreement are fair to, and in the
best interests of, AIOC, CIA, MRIA, Nyack, Pelham, RRG and WIC, respectively,
and each of their respective security holders and has thus approved the
respective Merger.  THE BOARD OF EACH OF AIOC, CIA, MRIA, NYACK, PELHAM, RRG AND
WIC RECOMMENDS THAT EACH SUCH ENTITY'S RESPECTIVE SECURITY HOLDERS VOTE IN FAVOR
OF THE RESPECTIVE MERGER PROPOSAL.

VALLEY RADIOLOGY GROUP'S REASONS FOR THE VALLEY MERGER

     The Valley Board considered the following factors in their decision to
vote in favor of the Valley Merger:

     .    Increased access to capital, potential to upgrade equipment and
          information systems at current practice sites, open new practice
          sites, and maintain a database required to manage HMO contracts

     .    Economies of scale obtained by pooled purchasing of equipment, 
          supplies and services

     .    Improved and more cost effective management

     .    Increased competitiveness in obtaining third party payor consent

     .    Similarity in culture and quality of practice with other Founding
          Affiliated Practices

     .    Radiologist leadership in governance of APPI

     .    Tax-free nature of transaction





                                       57
<PAGE>   94
     .    Exclusive contract to provide professional services for any APPI
          practice site within Valley's geographical area

     .    Advantageous allocation between professional and technical service
          revenues

     .    Potential to outsource hospital radiology departments using capital
          and management experience available through APPI

     The aggregate consideration (APPI Common Stock and cash) to be paid by APPI
to each security holder pursuant to the terms of each Merger Agreement and
Exchange Agreement shall fluctuate in relation to the Initial Public Offering
Price; provided, however, the aggregate consideration shall not be less than a
negotiated base aggregate consideration as set forth in each Merger Agreement
and Exchange Agreement.  The following tables present the potential exchange
ratios and cash consideration to be paid by APPI to each security holder,
assuming a range in the Initial Public Offering Price of $10 to $20.

     At the Effective Time of the Advanced Merger, the Advanced Common Stock
shall be converted as follows:

     (a)  Each share of APPI Common Stock issued and outstanding immediately
prior to the Effective Time shall remain issued and outstanding from and after
the Effective Time.

     (b)  Each share of Advanced Common Stock issued and outstanding at the
Effective Time shall cease to be outstanding and shall be converted into and
exchanged for the right to receive that number of shares of APPI Common Stock
(the "Advanced Exchange Ratio") and that amount of cash (the "Advanced Cash
Consideration") determined in accordance with the following:

          (i)  if the Initial Public Offering Price of the APPI Common Stock is
               $14.00 per share, then the Advanced Exchange Ratio shall be

          (ii)      if the Initial Public Offering Price of the APPI Common
                    Stock is greater than $14.00 per share, then the Advanced
                    Exchange Ratio shall be equal to the Advanced Base Exchange
                    Ratio and the Advanced Cash Consideration shall be equal to
                    the product of (x) the Advanced Base Cash Consideration and
                    (y) a fraction the numerator of which is the Initial Public
                    Offering Price and the denominator of which is $14.00; and

          (iii)     if the Initial Public Offering Price of the APPI Common

                    numerator of which is $14.00 and the denominator of which
                    is the Initial Public Offering Price and the Advanced Cash

DISSENTERS' RIGHTS REGARDING THE MERGERS

     The following discussion is not a complete statement of the laws
pertaining to dissenters' rights under the California Corporations Code (the
"CCC"), the Kansas General Corporation Code (the "KGCC"), the Maryland General
Corporation Law (the "MGCL"), the New York Business Corporation Law (the
"NYBCL") and the Texas Business Corporations Act (the "TBCA"), and is qualified
in its entirety by the full text of the sections referenced below, each of
which is set forth in its entirety as Appendices F, G, H, I and J,
respectively, to this Prospectus/Joint Proxy Statement.  Voting against,
abstaining from voting or failing to vote on approval and adoption of any
Merger Proposal or Exchange Proposal will not constitute a demand for fair
value within the meaning of the relevant acts.  Dissenting Security Holders (as
defined herein) are urged to consult legal counsel with respect to dissenters'
rights under the NYBCL, TBCA, CCC, KGCC and MGCL.

     Any Dissenting Security Holder who perfects the right to be paid the fair
market value of the shares of an Entity held by such Dissenting Security Holder
will generally recognize gain or loss, if any, for income tax purposes upon the
receipt of cash for such shares.  The amount of gain or loss and its character
as ordinary or capital gain or loss will be determined in accordance with the
applicable provisions of the Internal Revenue Code.  Advanced, Ide, M&S, South
Texas, San Antonio, Pacific, TMI, RNM, AIOC, CIA, MRIA, Nyack, Pelham, RRG, WIC
and Valley security holders considering the exercise of dissenters' rights
should consider the information set forth under "The Mergers, Exchanges and
Related Transactions -- Certain Income Tax Considerations."

     Holders of record of Advanced Common Stock, Ide Common Stock, M&S Common
Stock, South Texas Common Stock, San Antonio Common Stock, Pacific Common
Stock, TMI Common Stock, RNM Common Stock, AIOC Common Stock, CIA Common Stock,
MRIA Common Stock, Nyack Common Stock, Pelham Common Stock, RRG Common Stock,
WIC Common Stock and Valley Common Stock who comply with the applicable
procedures summarized herein (collectively, the "Dissenting Security Holders")
will be entitled to receive the fair value of the shares of the Entities held
by such Dissenting Security Holders.  For those Entities organized under the
laws of the State of New York (i.e., AIOC, CIA, Ide, MRIA, Nyack, Pelham, RRG
and WIC), such dissenters' rights are detailed in Sections 623 and 910 of the
NYBCL.  For those Entities organized under the State of Texas (i.e., M&S, San
Antonio and South Texas), such dissenters' rights are detailed in Articles 5.11
and 5.12 of the TBCA.  For those Entities organized under the State of
California (i.e., Pacific, TMI and Valley), such dissenters' rights are
detailed in Sections 1300 through 1304 of the CCC.  For RNM, such dissenters'
rights are detailed in Section 17-6712 of the KGCC.  For Advanced, such
dissenters' rights are detailed in Sections 3-202 and 3-203 of the MGCL.  A
Dissenting Security Holder must follow the applicable steps summarized below
properly and in a timely manner to properly assert the applicable Dissenting
Security Holder's rights.

  UNDER CALIFORNIA STATE LAW

     Under Section 1300 of the CCC, any holder of record of shares of Pacific
Common Stock, TMI Common Stock or Valley Common Stock who does not desire to
have such shares converted into shares of APPI Common Stock pursuant to the
applicable Entity's Merger may, alternatively, elect to receive a payment in
cash equal to the value of the shares of the Entity held by such Dissenting
Security Holder, provided that the Dissenting Security Holder complies with the
provisions of Sections 1301 through 1304 of the CCC.  A Dissenting Security
Holder contemplating the exercise of these dissenters' rights should carefully
review the provisions of Sections 1300 through 1304 of the CCC, which are
included in Appendix F attached to this Prospectus/Joint Proxy Statement.

     Set forth below is a brief summary of the procedures that a Dissenting
Security Holder must follow in order to perfect dissenters' rights under
California law.  This summary is not intended to be complete and is qualified
in its entirety by reference to Sections 1300 through 1304 of the CCC.

     If the Pacific Merger, TMI Merger or Valley Merger is approved by the
required vote of the respective Entity's security holders, each holder of
shares of such Entity's Common Stock who does not vote in favor of the
applicable Merger and who follows the procedures set forth in Section 1301 will
be entitled to have the shares held by such Dissenting Security Holder
purchased for cash at their fair market value.  The "fair market value" of the
shares of Pacific Common Stock, TMI Common Stock and/or Valley Common Stock, as
applicable, will be determined as of the day before the first announcement of
the terms of each of the proposed Mergers, excluding any appreciation or





                                       74
<PAGE>   111
depreciation in consequence of such proposed Merger.  Accordingly, the shares
of Pacific Common Stock, TMI Common Stock or Valley Common Stock, as
applicable, will be valued as if the applicable Merger had not occurred.

     Within ten days after approval of the Merger of an applicable Entity by
such Entity's security holders, the Entity must mail a notice of such approval
(the "Approval Notice") to each Dissenting Security Holder who has not voted in
favor of the Merger, together with a statement of the price determined by such
Entity to represent the fair market value of the shares held by such Dissenting
Security Holder, a brief description of the procedures to be followed in order
for such Dissenting Security Holder to pursue dissenters' rights, and a copy of
Sections 1300 through 1304 of the CCC.  The statement of price by such Entity
constitutes an offer by that Entity to purchase all shares held by a Dissenting
Security Holder at the stated amount.

     A Dissenting Security Holder must, within 30 days after the date on which
the Approval Notice is mailed to such Dissenting Security Holder, mail or
deliver the written demand to the applicable Entity stating that such
Dissenting Security Holder is demanding purchase of the shares of Pacific
Common Stock, TMI Common Stock or Valley Common Stock, as applicable, stating
the number of shares which such Entity must purchase, what the Dissenting
Security Holder claims to be the fair market value of such shares and enclosing
the applicable share certificates for endorsement by such Entity.

     If the applicable Entity and the Dissenting Security Holder agree that
such Dissenting Security Holder is entitled to receive payment for the shares
of the Entity held by such Dissenting Security Holder and agree upon the price
of such shares, the Entity must pay the Dissenting Security Holder such agreed
upon price plus interest thereon within 30 days from the later of (i) the date
upon which such price was agreed or (ii) the date all contractual conditions to
the applicable Merger are satisfied.

     If the applicable Entity denies that such Dissenting Security Holder is
entitled to receive payment for the shares of the Entity held by such
Dissenting Security Holder or if such Entity and the Dissenting Security Holder
fail to agree upon the fair market value of shares of Pacific Common Stock, TMI
Common Stock or Valley Common Stock, as applicable, then within six months
after the date that the Approval Notice was mailed to the Dissenting Security
Holders, any Dissenting Security Holder who has made a valid written purchase
demand and who has not voted in favor of approval and adoption of the
applicable Merger may file a complaint in California superior court requesting
a determination as to whether such Dissenting Security Holder is entitled to
receive payment for the shares of the Entity held by such Dissenting Security
Holder or as to the fair market value of such Dissenting Security Holder's
shares of Pacific Common Stock, TMI Common Stock and/or Valley Common Stock, as
applicable.

  UNDER KANSAS STATE LAW

     Under the KGCC, any holder of record of shares of RNM Common Stock who
does not desire to have such shares converted into shares of APPI Common Stock
pursuant to the RNM Merger may, alternatively, elect to receive a payment in
cash equal to the value of such Dissenting Security Holder's shares of RNM
Common Stock, provided that the Dissenting Security Holder complies with the
provisions of Section 17-6712 of the KGCC ("Section 17-6712").  A Dissenting
Security Holder contemplating the exercise of these dissenters' rights should
carefully review the provisions of Section 17-6712, which are included in
Appendix G attached to this Prospectus/Joint Proxy Statement.

     Set forth below is a brief summary of the procedures that a Dissenting
Security Holder must follow in order to perfect dissenters' rights under Kansas
law.  This summary is not intended to be complete and is qualified in its
entirety by reference to Section 17-6712 of the KGCC.

     Under Section 17-6712, a Dissenting Security Holder must deliver a written
notice of such Dissenting Security Holder's objection to the RNM Merger to RNM
prior to the RNM Meeting.  Any such objection should be sent to RNM at Medical
Park West Building, 823 S. Mulvane Street, Suite 1, Topeka, Kansas 66606,
Attention: President.  A Dissenting Security Holder cannot vote the shares of
RNM Common Stock held by such Dissenting Security Holder in favor of the RNM
Merger.  A SECURITY HOLDER WHO VOTES SHARES OF RNM COMMON STOCK HELD BY SUCH
DISSENTING SECURITY HOLDER IN FAVOR OF THE RNM MERGER WILL LOSE THE RIGHT TO
RECEIVE PAYMENT FOR SUCH SHARES PURSUANT TO SECTION 17-6712.

     If the RNM Merger is approved by the requisite percentage of shares of
RNM, then Dissenting Security Holders who have complied with the written
objection requirements discussed above will possess the right to receive
payment for the shares of RNM Common Stock respectively held by them.

     Within ten days after the effective date of the RNM Merger, APPI, as the
surviving corporation in the RNM Merger, must give written notice to each
former holder of shares of RNM Common Stock who has complied with the





                                       75
<PAGE>   112
written objection requirement discussed above that (i) the RNM Merger has
become effective and (ii) dissenters' rights are available for any or all of
such Dissenting Security Holder's shares of RNM Common Stock.  A Dissenting
Security Holder must then deliver a written demand for payment of the fair
value of the shares of RNM Common Stock held by such Dissenting Security Holder
within 20 days after the date of the mailing of APPI's notice.  Any such demand
by a Dissenting Security Holder should be sent to APPI at 901 Main Street,
Suite 2301, Dallas, Texas 75202, Attention: President.

     Within 30 days after the expiration of the 20 day period in which
Dissenting Security Holders must submit their demands for payment, APPI must
pay to each Dissenting Security Holder who has submitted such a demand the
value of such Dissenting Security Holder's shares of RNM Common Stock.  The
value of the Dissenting Security Holders' shares will be the value of the RNM
Common Stock as of the effective date of the RNM Merger, excluding any element
of value arising from the expectation or accomplishment of the RNM Merger.

     If APPI and a Dissenting Security Holder cannot agree upon a fair value
for the RNM Common Stock within such 30 day period, then either the Dissenting
Security Holder or APPI may file a petition in the District Court of Kansas
demanding a determination of the value of the RNM Common Stock of all
Dissenting Security Holders entitled to payment.  Such a petition must be filed
within four months after the expiration of the 30 day period discussed above.
Because APPI has no obligation to file such a petition, the failure of a
Dissenting Security Holder to do so within the period specified may lead to the
nullification of such Dissenting Security Holder's written demand for payment
for the shares of RNM Common Stock held by such Dissenting Security Holder.

     If a petition for appraisal described above is filed by a Dissenting
Security Holder, APPI must provide such Dissenting Security Holder with a
verified list of all Dissenting Security Holders who have demanded payment for
their shares and with whom agreements as to the value of the shares of RNM
Common Stock respectively held by them has not been reached.  The clerk of the
court will give APPI and all such Dissenting Security Holders notice of the
date and time for the hearing of such petition.

     After the hearing, the court will determine which Dissenting Security
Holders are entitled to an appraisal of the value of their RNM Common Stock and
will appoint an appraiser to make such an appraisal.  Prior to making a
determination of the value of the RNM Common Stock, the appraiser must afford
APPI and all Dissenting Security Holders participating in the appraisal an
opportunity to present evidence relating to the value of the RNM Common Stock.

     Following submission of a report by the appraiser of the value of the RNM
Common Stock, the court will make an ultimate determination of the value of the
shares of RNM Common Stock held by the Dissenting Security Holders.  The cost
of such appraisal, including a reasonable fee to and the reasonable expenses of
the appraiser, shall be determined by the court and taxed upon APPI and the
Dissenting Security Holders as the court deems appropriate.  Thereafter, the
court will direct APPI to pay each eligible Dissenting Security Holder the
value of the shares of RNM Common Stock held by such Dissenting Security
Holder, with interest thereon if the court so determines.  APPI need not make
such a payment to a Dissenting Security Holder unless and until the Dissenting
Security Holder surrenders the certificate representing the shares of RNM
Common Stock to APPI, at the address specified above.

  UNDER MARYLAND STATE LAW

     Under Section 3-202 of the MGCL ("Section 3-202"), any holder of record of
shares of Advanced Common Stock who does not desire to have such shares
converted into shares of APPI Common Stock pursuant to the Advanced Merger may,
alternatively, elect to receive payment in cash equal to the "fair value" of
such Dissenting Security Holder's shares of Advanced Common Stock, provided
that the Dissenting Security Holder complies with the provisions of Section
3-203 of the MGCL ("Section 3-203").  The term "fair value" is defined in
Section 3-202 to mean the value of the shares as of the close of business of
the date upon which the security holders approve the proposed merger to which
the Dissenting Security Holder objects, excluding any appreciation or
depreciation in anticipation of the proposed merger.  A Dissenting Security
Holder contemplating the exercise of dissenters' rights under the MGCL should
carefully review the provisions of Sections 3-202 and 3-203, which are included
in Appendix H attached to this Prospectus/Joint Proxy Statement.

     Set forth below is a brief summary of the procedures that a Dissenting
Security Holder must follow in order to perfect dissenters' rights under
Maryland law.  This summary is not intended to be complete and is qualified in
its entirety by reference to Sections 3-202 and 3-203 of the MGCL.

        Under Section 3-203, a Dissenting Security Holder must deliver a
written notice of such Dissenting Security Holder's objection to the Advanced
Merger Proposal to Advanced at or prior to the Advanced Meeting.  Any such
objection should be sent to Advanced at 7253 Ambassador Road, Baltimore,
Maryland 21244, Attention: President.  A





                                       76
<PAGE>   113
Dissenting Security Holder cannot vote the shares of Advanced Common Stock held
by such Dissenting Security Holder in favor of the Advanced Merger.  A SECURITY
HOLDER WHO VOTES THE SHARES OF ADVANCED COMMON STOCK HELD BY SUCH DISSENTING
SECURITY HOLDER IN FAVOR OF THE ADVANCED MERGER WILL LOSE THE RIGHT TO RECEIVE
PAYMENT FOR SUCH SHARES.

     If the Advanced Merger is approved by the requisite percentage of shares
of Advanced, then Dissenting Security Holders who have complied with the
written objection requirements discussed above will possess the right to
receive payment for the shares of Advanced Common Stock respectively held by
them.

     Promptly after the Effective Time of the Advanced Merger, Advanced, as the
surviving corporation in such Merger, must give written notice of the Effective
Time of the Advanced Merger to each former holder of shares of Advanced Common
Stock who has complied with the written objection requirement discussed above.
A Dissenting Security Holder must then deliver a written demand for payment of
the fair value of the shares of Advanced Common Stock held by such Dissenting
Security Holder to Advanced within 20 days after the Effective Time of the
Advanced Merger.  Any such demand by a Dissenting Security Holder should be
sent to Advanced at 7253 Ambassador Road, Baltimore, Maryland 21244, Attention:
President.

     Advanced may, at its option, send a written offer to pay each Dissenting
Security Holder who has made demand for payment what Advanced considers to be
the fair value of shares held by such Dissenting Security Holder.  Such offer
must be accompanied by the following financial information relating to Advanced
and any other information Advanced considers pertinent: (i) a balance sheet as
of a date not more than six months prior to the date of the offer and (ii) a
profit and loss statement for the 12 months ending on the date of the balance
sheet.

     Within 50 days of the Effective Time of the Advanced Merger, Advanced or
any Dissenting Security Holder who has not yet received payment for the shares
of Advanced Common Stock held by such Dissenting Security Holder may petition a
court of equity in the county in which the principal office of Advanced is
located for an appraisal to determine the fair value of the Advanced Common
Stock.  If more than one such petition is filed, the court will consolidate all
of the proceedings into one proceeding.

     If the court determines that a Dissenting Security Holder who has filed
such a petition is entitled to an appraisal, then it will appoint three
disinterested appraisers to determine the fair value of the Advanced Common
Stock.  Within 60 days after their appointment, unless the court establishes a
longer time, the appraisers must determine the fair value of the Advanced
Common Stock and must file a report with the court stating their conclusion and
the reasons therefor.  Each party to the appraisal proceedings will also
receive a copy of the appraisers' report.

     After consideration of the appraisers' report, the court will either
accept, modify or reject the appraisers' conclusion.  If the court rejects the
appraisers' conclusion, it may either remit the proceedings to the same or
other appraisers or it may make its own determination of the fair value of the
Advanced Common Stock.

     Once the fair value of the Advanced Common Stock is determined, Advanced
must pay each Dissenting Security Holder participating in the appraisal
proceedings the judicially determined value of the shares held by such
Dissenting Security Holder, together with interest, if the court so determines.
Advanced need not make such payment to a Dissenting Security Holder unless and
until the Dissenting Security Holder surrenders the certificate representing
the shares of Advanced Common Stock to Advanced, at the address specified
above, or to the transfer agent of Advanced.  The costs of the appraisal
proceedings shall be set by the court and assessed against Advanced or, if the
court determines that a Dissenting Security Holder failed to accept an offer
for payment by Advanced in good faith, against such Dissenting Security Holder.

  UNDER NEW YORK STATE LAW

     Under Section 910 of the NYBCL ("Section 910"), any holder of record of
shares of Ide Common Stock, AIOC Common Stock, CIA Common Stock, MRIA Common
Stock , Nyack Common Stock, Pelham Common Stock, RRG Common Stock or WIC Common
Stock who does not desire to have such shares converted into shares of APPI
Common Stock pursuant to the applicable Entity's Merger may, alternatively,
elect to receive a payment in cash equal to the value of the shares of the
applicable Entity held by such Dissenting Security Holder and certain other
rights and benefits, provided that the Dissenting Security Holder complies with
the provisions of Section 623 of the NYBCL ("Section 623").  A Dissenting
Security Holder contemplating the exercise of these dissenters' rights should
carefully review the provisions of Sections 623 and 910, which are included in
Appendix I attached to this Prospectus/Joint Proxy Statement.





                                       77
<PAGE>   114
     Set forth below is a brief summary of the procedures that a Dissenting
Security Holder must follow in order to perfect dissenters' rights under New
York law.  This summary is not intended to be complete and is qualified in its
entirety by reference to Sections 623 and 910 of the NYBCL.

     Under Section 623, a Dissenting Security Holder must file a written
objection to the applicable Entity's Merger with such Entity prior to such
Entity's Meeting or at such Meeting but prior to the vote on the applicable
Merger Proposal.  Such written objection should include the Dissenting Security
Holder's notice of election to dissent, the Dissenting Security Holder's name
and residence address, the number and class of shares as to which such
Dissenting Security Holder dissents and a demand for payment of the fair value
of such shares if the Entity's Merger is approved.

     If the security holders of an applicable Entity approve such Entity's
Merger, then the Entity must give written notice of such approval to each
Dissenting Security Holder who filed a written objection and who did not vote
in favor of such Merger Proposal within ten days of the date such Merger
Proposal was approved.  A SECURITY HOLDER WHO VOTES IN FAVOR OF AN ENTITY'S
MERGER WILL BE DEEMED TO HAVE ELECTED NOT TO ENFORCE THE RIGHT TO RECEIVE
PAYMENT FOR THE SHARES OF SUCH ENTITY HELD BY SUCH DISSENTING SECURITY HOLDER.

     If a Dissenting Security Holder of an Entity holds shares represented by
certificates, such Dissenting Security Holder must submit all applicable
certificates to the Entity or to the applicable transfer agent of such Entity,
within one month after such Dissenting Security Holder files a written notice
of election to dissent.  Any Dissenting Security Holder holding shares
represented by certificates who does not submit such certificates in this
manner may lose such Dissenting Security Holder's dissenters' rights under
Section 623.

     The applicable Entity or, if the Merger of such Entity has been
consummated, APPI must, make a written offer (the "Purchase Offer") to each
Dissenting Security Holder to pay a specified price (the "Offer Price") which
the Entity or APPI, as applicable, believes to be a "fair value" under Section
623 for the shares of the Entity held by such Dissenting Security Holder.  Such
Purchase Offer must be made within 15 days of the later of (i) the consummation
of the applicable Merger or (ii) the expiration of the period within which
security holders may file their notices of election to dissent.  All Dissenting
Security Holders holding the same class of securities of the Entity must be
offered the same price per share of such class of securities.

     If the applicable Merger has been consummated at the time the Purchase
Offer is made, APPI must, concurrently with the Purchase Offer, provide to each
Dissenting Security Holder (i) who has submitted the certificates evidencing
the applicable shares of the Entity, as provided above, an advanced payment of
an amount equal to 80% of the Offer Price, and (ii) who has not yet submitted
the requisite certificates, a statement that an advanced payment of an amount
equal to 80% of the Offer Price will be made promptly upon the submission of
such certificates.  If the Purchase Offer is made prior to the consummation of
the applicable Merger, then such advanced payments or statements relating to
advanced payments, as the case may be, will be made upon the consummation of
the applicable Merger.

     If, within 30 days after the date of a Purchase Offer, a Dissenting
Security Holder accepts the Purchase Offer or if the Dissenting Security Holder
and the Entity or APPI, as applicable, agree upon an alternate value for the
Dissenting Security Holder's shares, then any remaining payments owed to the
Dissenting Security Holder must be made to the Dissenting Security Holder
within 60 days after the date of the Purchase Offer or 60 days after the
applicable Merger is consummated, whichever is later.

     If (i) the Entity or APPI, as applicable, fails to make a Purchase Offer
within the required 15-day period discussed above or (ii) a Dissenting Security
Holder rejects the Purchase Offer and such Dissenting Security Holder and the
Entity or APPI, as applicable, cannot within 30 days of the date of the
Purchase Offer agree upon a value for the shares of the Entity held by such
Dissenting Security Holder, then the following procedures will apply:

     (1)  The Entity or APPI, as applicable, will institute a special
          proceeding in the Supreme Court in the judicial district in which the
          office of the Entity is located within 20 days after the expiration
          of the 15 or 30-day period discussed above, as the case may be, to
          determine the rights of the Dissenting Security Holder and to fix the
          fair value of such Dissenting Security Holder's shares.

     (2)  The court will determine (i) whether the Dissenting Security Holder
          is entitled to receive payment for such Dissenting Security Holder's
          shares, and (ii) the fair value for such shares.  In determining the
          fair value for such shares, the court will consider the nature of the
          transaction giving rise to the Dissenting Security Holder's right to
          receive payment under Section 623, the concepts and methods
          customarily used in the relevant securities and financial markets to
          determine the value of the share of a corporation engaging in a
          similar transaction under comparable circumstances, and all other
          relevant factors.





                                       78
<PAGE>   115
     (3)  Each party to the proceeding must bear its own costs and expenses,
          including attorneys' and experts' fees, unless the court, in its
          discretion, assesses all of part of such costs and expenses against
          either the Dissenting Security Holder or the Entity or APPI, as
          applicable.

     (4)  Within 60 days after the final determination of the court proceeding,
          the Entity or APPI, as applicable, will pay to the Dissenting
          Security Holder the amount found by the court to be owed to such
          Dissenting Security Holder upon surrender of the certificates for any
          such shares represented by such certificates.

UNDER TEXAS STATE LAW

     Any holder of record of shares of M&S Common Stock, San Antonio Common
Stock or South Texas Common Stock who does not desire to have such shares
converted into shares of APPI Common Stock pursuant to the applicable Entity's
Merger may, alternatively, elect to receive the fair value of such shares,
provided that the Dissenting Security Holder complies with the provisions of
Articles 5.11 and 5.12 of the TBCA.  The term "fair value" is defined in
Article 5.12 to mean the value of the shares as of the day immediately
preceding the applicable Entity's Meeting, excluding any appreciation or
depreciation in anticipation of the proposed Merger.  A Dissenting Security
Holder contemplating the exercise of dissenters' rights under the TBCA should
carefully review the provisions of Articles 5.11 and 5.12 which are included in
Appendix J attached to this Prospectus/Joint Proxy Statement.

     Set forth below is a brief summary of the procedures that a Dissenting
Security Holder must follow in order to perfect dissenters' rights under Texas
law.  This summary is not intended to be complete and is qualified in its
entirety by reference to Articles 5.11 and 5.12 of the TBCA.

     A Dissenting Security Holder must file a written objection to an
applicable Entity's Merger with such Entity prior to such Entity's Meeting.
Such written objection should include (i) a statement to the effect that such
Dissenting Security Holder intends to exercise dissenters' rights if the Merger
Proposal is approved, and (ii) the address of such Dissenting Security Holder.

     If the applicable Entity's Merger is approved by the requisite percentage
of shares, then APPI, as the surviving corporation in the Merger, must deliver
or mail to each Dissenting Security Holder who filed a written objection and
did not vote in favor of such Merger a written notice of such approval (the
"Approval Notice").  A SECURITY HOLDER WHO VOTES IN FAVOR OF AN ENTITY'S MERGER
WILL LOSE THE RIGHT TO RECEIVE PAYMENT FOR THE SHARES OF SUCH ENTITY'S COMMON
STOCK HELD BY SUCH DISSENTING SECURITY HOLDER.

     Within ten days from the date of delivery or mailing of the Approval
Notice, a Dissenting Security Holder must make a written demand to APPI for
payment of the fair value of the shares of M&S Common Stock, San Antonio Common
Stock or South Texas Common Stock, as applicable, held by such Dissenting
Security Holder.  Such demand must state the number and class of shares owned
by such Dissenting Security Holder and the fair value of such shares as
estimated by the Dissenting Security Holder.

     Within 20 days after receipt by APPI of a demand by a Dissenting Security
Holder for payment of the fair value of the shares held by such Dissenting
Security Holder, APPI shall deliver or mail to the Dissenting Security Holder a
written notice to the effect that APPI will pay within 90 days after the
effective date of the Merger (i) the amount claimed, upon the surrender of the
duly endorsed share certificates, or (ii) some other amount as the fair value,
upon receipt of a notice from the Dissenting Security Holder within 60 days
after the date of such offer that such Dissenting Security Holder will accept
such amount in exchange for surrender of the duly endorsed share certificates.
If APPI and the Dissenting Security Holder can agree upon the fair value, such
value will be paid to the Dissenting Security Holder and such Dissenting
Security Holder shall cease to have any interest in such shares or in either
the Entity or APPI.  If agreement as to the fair value cannot be reached,
either the Dissenting Security Holder or APPI may, within the time limits
prescribed by Article 5.12, file a petition in Texas court asking for a finding
and determination of the fair value of such shares.  Court costs shall be
allocated between the parties in such manner as the court shall determine to be
fair and equitable.

GOVERNMENT AND REGULATORY APPROVALS

     It is a condition to the consummation of the transactions contemplated by
each Merger Agreement and Exchange Agreement that each of the Entities must
have received necessary government and regulatory approvals prior to the Merger
or Exchange, as the case may be.  At any time before or after the Effective
Time of the Mergers or the Closing Date of the Exchanges, the Federal Trade
Commission or the Antitrust Division of the United States Department of Justice
or any state could take action pursuant to the federal or state antitrust laws
to seek to enjoin the consummation

of a particular Merger or Exchange.  Private parties may also seek to take
legal action under the antitrust laws.  Based on information available to them,
each of Advanced, Ide, M&S, Lexington, Madison, South Texas, South Texas No. 1
San Antonio, San Antonio No. 2, Pacific, TMI, RNM, AIOC, CIA MRIA, Nyack,
Pelham, RRG, WIC and Valley believes that the Merger or Exchange applicable to
each such Entity can be effected in compliance with federal and state antitrust
laws.  Advanced, Ide, M&S, Lexington, Madison, South Texas, South Texas No. 1,
San Antonio, San Antonio No. 2, Pacific, TMI, RNM, AIOC, CIA, MRIA, Nyack,
Pelham, RRG, WIC and Valley are aware of no governmental or regulatory
approvals required for the consummation of the respective Merger or Exchange,
other than compliance with federal and applicable state securities and
corporate laws, and the required transfer of or amendment to certain of the
Advanced, Ide, M&S, Lexington, Madison, South Texas, South Texas No. 1, San
Antonio, San Antonio No. 2, Pacific, TMI, RNM, AIOC, CIA, MRIA, Nyack, Pelham,
RRG, WIC and Valley licenses and permits.

CERTAIN INCOME TAX CONSIDERATIONS

     The foregoing summary of the federal income tax consequences of the
Mergers, Exchanges and related transactions is for general information only.
Security holders and partners are urged to consult their own tax advisers as to
the particular consequences to them of the applicable Merger or Exchange,
including the application of state, local and foreign tax laws.  This summary
may be inapplicable to security holders or partners who are not citizens or
residents of the United States.

     Haynes and Boone, L.L.P., special counsel to APPI, upon the basis of
assumed consummation of the Mergers and Exchanges and representations of the
officers of APPI, each of the Entities and the security holders will render an
opinion as of the Effective Time of each Merger and the Closing Date of each
Exchange that each Merger and Exchange will constitute a tax-free reorganization
under either Section 351 or Section 368(a) of the Internal Revenue Code.  If so
treated, each Merger and Exchange will have the following general federal income
tax consequences: (i) except as set forth below, no gain or loss will be
recognized by the security holders or partners of any of the Entities who
exchange their Old Shares or Old Partnership Interests for APPI Common Stock
pursuant to the Merger or Exchange, as the case may be, (ii) the aggregate tax
basis of APPI Common Stock received in the Merger or Exchange, as the case may
be, will equal the aggregate tax basis of the Old Shares or Old Partnership
Interests, as the case may be, exchanged therefor, (iii) no gain or loss will be
recognized by each of the Entities in connection with the Merger or Exchange, as
the case may be, (iv) provided that the Old Shares or Old Partnership Interests
are held as a capital asset at the Effective Time of a given Merger or the
Closing Date of a given Exchange, the holding period of APPI Common Stock will
include the holding period of such Old Shares or Old Partnership Interests, and
(v) security holders or partners of any of the Entities will recognize gain only
to the extent that they receive (or are deemed to receive) cash or property
other than APPI Common Stock.  An opinion of counsel is not binding on the
Internal Revenue Service or the courts. No assurance can be given that the
tax-deferred characterization of the Mergers and Exchanges will not be
challenged or, if challenged, will be defended successfully.  If the tax
characterization of the Mergers and Exchanges is successfully challenged, there
may be significant adverse tax consequences to the Entities and their respective
security holders or partners.

ACCOUNTING TREATMENT

     SAB 48 states that when a company acquires assets from promoters and
security holders in exchange for stock just prior to, or at the time of, its
initial public offering, such assets should be recorded at the historical cost
to each such promoter or security holder.  Each security holder of each of the
Entities is involved as a promoter of its respective Merger or Exchange and the
related Initial Public Offering.  Accordingly, the assets and liabilities to be
acquired by APPI or a subsidiary thereof in connection with the Merger
Transactions and Exchange Transactions will be recorded on the APPI balance
sheet in the same amounts as reflected on the balance sheets of the Entities at
the Effective Time of the applicable Merger or Closing Date of the applicable
Exchange.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

     The following unaudited pro forma combined financial statements give effect
to the Mergers and Exchanges as a combination of promoter interests, at
historical costs, and are based upon the historical financial statements of APPI
and each of the Founding Affiliated Practices.  In addition, the unaudited pro
forma combined financial statements give effect to the Initial Public Offering
(assuming an Initial Public Offering Price of $15.00 per share) and the
conversion of the Convertible Notes.  The unaudited pro forma combined
statements of operations gives effect to the completion of such transactions as
if they had occurred on January 1, 1996, and the unaudited pro forma combined
balance sheet gives effect to the completion of such transactions as if they had
occurred on March 31, 1997.  The unaudited pro forma combined financial
statements for the year ended December 31, 1996 have been prepared using
financial information for the 1996 fiscal years of each of the Founding
Affiliated Practices (which are calendar years except for Rockland Radiological
Group, which has a September 30 fiscal year) other than The Ide Group which has
a June 30 fiscal year and for which





                                       80
<PAGE>   117
information for the twelve month period ended December 31, 1996 has been used
in preparing the unaudited pro forma combined financial statements.  The
unaudited pro forma combined financial statements and notes thereto should be
read in connection with the other financial information, including the audited
financial statements of APPI and each of the Founding Affiliates Practices and
notes thereto, included elsewhere in this Prospectus.

     The pro forma combined financial statements are presented for illustrative
purposes only and are not necessarily indicative of the operating results or
financial position that would have been achieved if the Mergers and Exchanges,
the conversion of the Convertible Notes and the Initial Public Offering had been
consummated at the beginning of the periods presented, nor are they necessarily
indicative of future operating results of the Company.  The pro forma combined
financial information does not give effect to any cost savings or integration
that may result from the Mergers and Exchanges.

                       AMERICAN PHYSICIAN PARTNERS, INC.
 
               NOTES TO PRO FORMA COMBINED FINANCIAL INFORMATION
 
     APPI was incorporated in April 1996 and has conducted no significant
operations and generated no revenue to date other than in connection with this
offering and the Reorganizations. The following is a summary of the adjustments
reflected in the Unaudited Pro Forma Consolidated Financial Statements assuming
the Reorganizations, the offering and conversion of the Convertible Notes. The
Reorganizations will be accounted for as a combination of promoter interests, at
historical costs, under generally accepted accounting principles. APPI will not
be acquiring equity interests in the Founding Affiliated Practices, but will be
acquiring substantially all of the assets of the Founding Affiliated Practices.
 
     Upon completion of the Reorganizations, the Company will not consolidate
the financial position or results of operations of the Founding Affiliated
Practices. The Company presents physician groups revenue, net and amounts
retained by physician groups from which service fee revenues are derived and
earned by the Company for display purposes only.
 
PHYSICIAN GROUPS REVENUE, NET

     Physician groups revenue, net represents the revenue of the affiliated
physician groups reported at the estimated realizable amounts from patients,
third-party payors and others for services rendered, net of contractual and
other adjustments. Physician groups revenue, net is accounted for and provisions
for estimated third-party payor adjustments are estimated and recorded in the
period in which the services are provided. Any adjustment to the amounts is
recorded in the period in which the revised amount is determined.
 
SERVICE FEE REVENUE

     Service fee revenue represents physician groups revenue, net less amounts
retained by physician groups. The service fees payable to the Company by the
Affiliated Practices under the Service Agreements vary based on the fair market
value, as determined in arms' length negotiations, of the nature and amount of
services provided. Such fees are payable monthly and consist of various
combinations of the following: (i) a fixed percentage of the practice's revenue
from physician and certain other medical services; (ii) all or a substantial
portion of the revenue derived from facility and non-physician fees generated by
ICs owned, operated or managed by the Company; (iii) operating and non-operating
expenses of the Founding Affiliated Practices paid by the Company; and (iv)
certain negotiated performance and other adjustments. The service fees for two
practices are subject to state law requiring flat fees that are subject to
renegotiation on an annual basis.
 
PRO FORMA CONSOLIDATED BALANCE SHEET
 
     The adjustments reflected in the unaudited pro forma consolidated balance
sheet are as follows:
 
        (a)  To eliminate assets not acquired and liabilities not assumed by the
             Company.
 
        (b)  To record the establishment of deferred income taxes for the
             Company after the Reorganizations.
 
        (c)  To record the issuance of Common Stock to the Founding Affiliated
             Practices.
 
        (d)  To record the reclassification of the Founding Affiliated
             Practices's earnings (deficit) accumulated prior to the offering to
             additional paid-in capital.
 
        (e)  To reflect the conversion of all $3,500,000 of Convertible Notes
             issued by the Company into 437,500 shares of Common Stock at the
             time of the offering.
 
        (f)  To reflect the effects of the offering, including the use of
             estimated net cash proceeds from the issuance of Common Stock to
             reduce debt.
 
PRO FORMA CONSOLIDATED STATEMENTS OF OPERATIONS
 
     The adjustments reflected in the unaudited pro forma consolidated
statements of operations for the three months ended March 31, 1997 and year
ended December 31, 1996 are as follows:
 
        (g)  As part of the Reorganizations, the Company will own minority
             interests in entities that were wholly-owned by the Founding
             Affiliated Practices or their shareholders.
 
                                       84
<PAGE>   121
 
        (h)  To eliminate the revenue and related expenses associated with a
             division which will no longer be a part of an Affiliated Practice
             subsequent to the Reorganizations.
 
        (i)  To eliminate a non-recurring gain generated through the receipt of
             proceeds from a cash value life insurance policy by one of the
             founding Affiliated Practices.
 
        (j)  To record amounts retained by physician groups as specified in the
             Service Agreements entered into with each of the Founding
             Affiliated Practices.
 
        (k)  To eliminate the historical costs of affiliated physician services
             for each of the Founding Affiliated Practices. The amounts retained
             by physician groups will be used to pay physicians' compensation
             and benefits pursuant to employment agreements between the practice
             and each individual physician.
 
        (l)  To record federal and state income taxes at an estimated effective
             rate of 40%, which consists of a 34% federal statutory tax rate
             and an average state statutory tax rate of 6%. Prior to the
             Reorganizations, certain of the Founding Affiliated Practices were
             S corporations or general partnerships with such entities owing no

consummation of such transactions.

     OPERATION, MANAGEMENT AND BUSINESS FOLLOWING THE MERGERS AND EXCHANGES

GENERAL

     APPI is a radiology practice management company focused on the
development, consolidation and management of integrated radiology and imaging
center networks.  Upon completion of the Initial Public Offering, the Company
will provide practice management services to seven radiology practices
consisting of 218 physicians practicing at 42 hospitals and 65 ICs in
California, Kansas, Maryland, New York and Texas.  The Company will derive its
revenue from the provision of management, administrative, technical and other
non-medical services to physicians of Affiliated Practices.

     The Founding Affiliated Practices provide a wide range of diagnostic and
therapeutic services, including x-ray and fluoroscopy, magnetic resonance
imaging, computed tomography, mammography, ultrasound, nuclear medicine,
radiation oncology and interventional radiology.  The Founding Affiliated
Practices were selected based on a variety of factors, including:  physician
and practice credentials and reputation; competitive market position;
subspecialty mix of physicians; historical financial performance and growth
potential; and willingness to embrace the Company's vision and philosophy
regarding the provision of radiology services.  The Company intends to provide
Affiliated Practices with the necessary capital resources and expertise to
invest in new technologies, complete consolidating acquisitions, implement
sophisticated management information systems, promote efficient practice
patterns, develop coordinated marketing efforts and realize purchasing
economies of scale.

     The Company's objective is to develop integrated networks of radiology
groups and ICs that can provide wide geographic coverage and subspecialty
expertise.  The Company intends to provide the networks with sophisticated
management, state-of-the-art information systems and appropriate capital for
expansion.  The Company's strategy is to (i) emphasize quality service, (ii)
expand within its selected markets, (iii) improve operating efficiencies within
the Affiliated Practices and (iv) expand into new regional markets through
acquisitions of or affiliations with additional radiology practices and ICs.

     The Company was incorporated in Delaware in April 1996, and prior to the
Initial Public Offering has not conducted any significant operations.  In
connection with the Mergers, Exchanges and Reorganizations, APPI will acquire
certain assets and liabilities of, and enter into long-term Service Agreements
with, the Founding Affiliated Practices.  Pursuant to the Service Agreements,
the Company will provide management, administrative, technical  and non-medical
business services to the Founding Affiliated Practices in exchange for a
service fee.  The Service Agreements have a 40-year term, subject to earlier
termination under certain circumstances.

INDUSTRY BACKGROUND

  MARKET OVERVIEW

     The Health Care Financing Administration estimates that national health
care spending in 1995 was approximately $1 trillion, including approximately
$200 billion for physician services and an additional $600 billion for health
care expenditures under the control or influence of physicians.  According to
the American College of Radiology, an estimated 350 million radiological
procedures were performed in the United States during 1995.  Total spending on
radiology services including diagnostic imaging, interventional radiology and
radiation oncology was estimated at $56 to $70 billion according to a 1995
report prepared by SMG Marketing Group.  Diagnostic imaging, including
interventional radiology procedures, accounted for approximately 82% of the
aggregate amount spent on radiological services performed in the United States,
with radiation oncology services accounting for approximately 18%.

     Fees charged for diagnostic imaging, interventional radiology and
radiation oncology procedures consist generally of a technical component
relating to facilities, equipment and non-physician personnel and a
professional component consisting of fees paid to physicians for the
interpretation of diagnostic images, the performance of interventional
radiology procedures and the treatment of radiation oncology patients.
Technical facilities are located within hospitals and in approximately 2,200
outpatient centers throughout the United States.  Professional radiology
services are provided by board certified radiologists, general practitioners
and other specialists.  There are approximately 3,200 radiology groups in the
United States comprised of approximately 27,000 practicing radiologists.  These
groups have a typical size





                                       86

<PAGE>   123
of six members, but vary in size up to approximately 100 physicians serving a
specific market.  Approximately 88% of all radiologists perform diagnostic
procedures, including interventional radiology procedures, and approximately
12% practice radiation oncology.  The Company believes that few radiologists or
radiology groups are currently affiliated with physician practice management
companies.

  RADIOLOGY

     In general, radiology includes diagnostic imaging, interventional
radiology and radiation oncology.  Imaging procedures use energy waves to
penetrate human tissue and generate images of the body, which can be recorded
on film or digitized for display on a video monitor.  Diagnostic imaging
procedures are used to diagnose diseases and physical injuries and are
performed in hospitals, physicians' offices, outpatient centers and ICs.
Interventional radiology procedures include the use of radiological methods to
monitor and guide catheters, stents, drains and needles to open clogged
vessels, relieve obstructed kidneys, perform biopsies of mass lesions, drain
abscess collections and lower pressure in certain vessels.  Generally, these
interventional procedures are more time efficient, more cost-effective and less
invasive than surgical alternatives and have historically been performed in a
hospital setting to enable utilization of hospital support services.  Radiation
oncology procedures use a variety of radiation sources to treat cancer and/or
relieve pain caused by certain tumors and are performed in hospitals and
free-standing outpatient centers.

     The principal diagnostic imaging modalities include the following, all of
which are non-invasive:

               General Radiology: X-Ray and Fluoroscopy.  X-rays utilize
          roentgen rays to penetrate the body and record images of organs and
          structures on film.  Fluoroscopy utilizes ionizing radiation combined
          with a video viewing system for real time monitoring of organs.
          X-ray and fluoroscopy are the most frequently used imaging
          modalities.

               Computed Tomography ("CT").  CT utilizes a computer to direct
          the movement of an x-ray tube to produce multiple cross sectional
          images of a particular organ or area of the body.  CT is used to
          detect tumors and other conditions affecting bones and internal
          organs.  It is also used to detect the occurrence of strokes,
          hemorrhages and infections.  CT provides higher resolution images
          than conventional x-rays, but generally not as well defined as those
          produced by magnetic resonance.

               Magnetic Resonance Imaging.  MRI utilizes a strong magnetic
          field in conjunction with low energy electromagnetic waves which are
          processed by a computer to produce high-resolution images of body
          tissue including the brain, spine, abdomen, heart and extremities.
          Unlike CT and conventional x-rays, MRI does not utilize ionizing
          radiation, which can cause tissue damage in high doses.

               Mammography.  Mammography is a specialized form of radiology
          utilizing low dosage x-rays to visualize breast tissue and is the
          primary screening tool for breast cancer.  Mammography procedures
          also include the biopsy of cells to assist in the diagnosis of breast
          cancer.

               Ultrasound.  Ultrasound imaging utilizes high-frequency sound
          waves to develop images of internal organs, unborn fetuses and the
          vascular system.  Ultrasound has widespread applications,
          particularly for procedures in obstetrics, gynecology and cardiology.

               Nuclear Medicine.  Nuclear medicine utilizes short-lived
          radioactive isotopes which release small amounts of radiation that
          can be recorded by a gamma camera and processed by a computer to
          produce an image of various anatomical structures or to assess the
          function of various organs such as the heart, kidneys, thyroid and
          bones.  Nuclear medicine is used primarily to study anatomic and
          metabolic functions.

  TRENDS IN RADIOLOGY

     Technological Advancements.  The Company believes that advances in
technology, including the development and continued enhancements of MRI, CT,
nuclear medicine, ultrasound and interventional radiology have contributed to
the growth of the diagnostic imaging industry.  These technological advances
have produced diagnostic procedures that are safer, more accurate and
less-invasive than techniques previously utilized.  While traditional x-rays
continue to be the primary imaging modality based on the number of procedures
performed, the use of advanced diagnostic imaging modalities such as MRI and CT
has increased rapidly in recent years because these modalities allow physicians
to diagnose a wide variety of diseases and injuries quickly and accurately
without exploratory surgery or other surgical or invasive procedures, which are
usually more expensive, involve greater risk to the patient and result in
longer rehabilitation time.  As a result, hospital days are shortened or
eliminated and time lost from work is significantly reduced.  In addition,
diagnostic imaging is increasingly used as a screening tool for preventive
care.  The Company





                                       87

<PAGE>   124
believes that future technological advances will enhance the ability of
radiologists to diagnose and direct treatment, thereby lowering overall health
care costs.

     Recent technological advancements include: magnetic resonance
spectroscopy, which can differentiate malignant from benign lesions; magnetic
resonance angiography, which can produce three-dimensional images of body parts
and assess the status of blood vessels; spiral computed tomography, which
permits three-dimensional images of body parts; monoclonal antibody studies
utilizing nuclear medicine to localize certain cancers that would otherwise be
difficult to detect or treat; and the development of teleradiology, which
digitally transmits radiological images from one location to another for
interpretation.  The Company believes that the utilization of both the
diagnostic and therapeutic capabilities of radiology will continue to increase
because of its cost-effective, time-efficient and risk/benefit advantages over
alternative procedures (including surgery) and that newer technologies and
future technological advancements will result in further subspecialization of
professional radiological services.

     Reimbursement Patterns.  Payment for radiology services comes primarily
from third-party payors such as private insurers (including traditional
indemnity insurance plans), managed care plans (including HMOs and PPOs) and
governmental payors (including Medicare and Medicaid).  Historically,
radiologists and other physicians generally provided medical services on a
fee-for-service basis.  The fee-for-service model provides few incentives for
the efficient utilization of resources and has contributed to increases in
health care costs at rates significantly higher than inflation.  As managed
care entities and other payors have focused on providing care in a more
cost-effective manner, they have demanded and received significant discounts
from fee-for-service rates charged for radiological procedures.  As a result,
physicians have seen a decrease in per procedure reimbursements from managed
care and governmental entities for such procedures.  More recently, payors have
focused on shifting more of the financial risk for the provision of
cost-effective services to providers through capitation and other risk-sharing
arrangements.  The Company believes that this reimbursement trend decreases the
attractiveness of under-utilized imaging equipment within a general
practitioner's office and will accelerate the centralization of resources to
high-volume centers.

     According to an article published in the American Journal of Radiology in
1993, approximately 64% of all radiological procedures (primarily x-rays and
ultrasound) performed in freestanding ICs and physicians' offices were
performed by non-radiologist physicians including internists, family and
general practitioners and orthopedists.  The Company believes that the general
diagnostic imaging services performed by non-radiologists may be directed to
radiologists by managed care entities seeking to have services performed at the
lowest overall cost.  As a result, the Company believes that managed care
entities provided with utilization  reports will focus on reducing costs by
shifting radiological procedures performed by non-radiologists to radiologists.

     Consolidation of ICs.  Concurrent with the growth of managed care and
strict controls on Medicare reimbursement for inpatient costs, diagnostic
imaging services began to shift from hospital settings to ICs in the early
1980s.  While many of these ICs were developed by physicians and hospitals, a
subsequent change in federal law restricted the referral of patients by a
physician to a facility in which the physician maintained an ownership
interest.  As a result, many physicians sold their interests in ICs to
hospitals, radiologists and companies engaged exclusively in the ownership,
operation and management of ICs.  The Company believes that many of these
entities have and will continue to consolidate the ownership of ICs.

     Referral Sources.  Non-radiologists, including specialists and primary
care physicians, direct the utilization of radiology services.  Most industry
marketing has been focused on developing relationships with these referring
physicians.  As more patients move to managed care plans, the Company believes
physicians will have fewer referral options for diagnostic imaging procedures.
In addition, the Company believes that managed care entities will increasingly
demand that providers of radiology services share in the financial risks
associated with providing services for the lives covered by the managed care
entities.  As the choices for radiology referrals decrease, the Company
believes that quality of care, subspecialty expertise and patient and referring
physician satisfaction will be important factors in determining referral
patterns.

     Trends in Radiology Organizations.  The trends toward managed care, cost
containment and health care consolidation have combined to limit the number of
positions available and the salaries paid to radiologists.  In addition, small
independent physician groups and individual practices are typically at a
competitive disadvantage to larger associations or networks of physicians
because they lack the capital necessary to (i) expand the geographic coverage
of the practice and the imaging modalities offered, (ii) develop
state-of-the-art information systems and (iii) purchase costly new imaging
technologies, each of which can improve quality of care and reduce costs.
Generally, they also lack the cost accounting and quality management systems
necessary to allow physicians to price and monitor complex risk-sharing
arrangements with third-party payors.  Additionally, small to medium-sized
groups and individual practices often do not have contractual ties with other
providers nor do they have the ability to offer a broad range of subspecialty
imaging services.  Small practices often have higher operating costs (since
overhead must be spread over a relatively small





                                       88
<PAGE>   125
revenue base) and minimal vendor purchasing power.  In order to remain
competitive in the changing medical service environment, radiologists are
beginning to affiliate with or create larger organizations by adding
radiologists to their groups, creating or joining a network or an independent
physician association or affiliating with a physician practice management
entity such as the Company.

BUSINESS STRATEGY

     The Company's objective is to develop integrated networks of radiology
groups and ICs that can provide wide geographic coverage and subspecialty
expertise.  The Company intends to provide the networks with sophisticated
management, state-of-the-art information systems and appropriate capital for
expansion.  The Company's strategy is to (i) emphasize quality service, (ii)
expand within its selected markets, (iii) improve operating efficiencies within
the Affiliated Practices and (iv) expand into new regional markets through
acquisitions of or affiliations with additional radiology practices and ICs.

  EMPHASIZE QUALITY SERVICE

     The Company plans to make patient service and referring physician
satisfaction a key element of its strategy.  The Company intends to form
regional service networks and invest in advanced teleradiology technologies to
provide greater geographic coverage, improve response time and increase overall
patient accessibility.  The Company will seek to offer, through its Affiliated
Practices, subspecialty expertise such as interventional radiology and
radiation oncology to address the full range of radiology service needs of
patients, referring physicians, hospitals and payors.  The Company also intends
to provide capital to the Affiliated Practices to upgrade existing imaging
equipment and purchase equipment for newer modalities.  In addition, the
Company plans to implement information systems which will provide the Company's
payors and referral sources with outcomes data, cost analyses, utilization
management data and other analyses, in each case with the objective of
maximizing patient, referring physician, hospital and payor satisfaction.

  EXPAND WITHIN EXISTING REGIONAL MARKETS

     A key element of the Company's strategy is to expand and leverage the
resources and capabilities of its Affiliated Practices to offer high-quality,
comprehensive and competitively priced diagnostic, interventional and
therapeutic radiology programs within selected markets.  The Company believes
that cost-conscious payors, particularly those interested in utilizing or
implementing risk sharing or global capitation arrangements, will prefer to
contract with a single provider for a full range of radiology services within
select geographic markets.  The Company plans to acquire and affiliate with
additional complementary radiology practices and, when feasible, acquire,
operate and manage ICs to broaden the range of, and increase the capacity to
deliver, services within its markets.  The Company intends to market its
comprehensive service offerings and geographic coverage to obtain payor
contracts.

  IMPROVE OPERATING EFFICIENCIES

     The Company intends to utilize its management infrastructure and the
collective knowledge of and information generated by its Affiliated Practices
to identify and promote practice operating efficiencies that benefit all
Affiliated Practices.  The Company believes that information technology is
critical to such efforts and plans to implement sophisticated management and
financial information systems to obtain and disseminate information relating to
practice patterns, equipment utilization, facilities and personnel and
operating profitability.  The Company believes such information will enable
Affiliated Practices to enhance quality of care, increase revenue, improve cash
management and more effectively control costs.  The Company believes that the
establishment of systems that promote "best practices" and operating
efficiencies can provide the Company and its Affiliated Practices with a
competitive advantage in negotiating and obtaining managed care contracts.  In
addition, the Company intends to capitalize on the size and purchasing power of
the combined Affiliated Practices to take advantage of economies of scale and
to reduce the cost of administering and operating such practices.

  EXPAND INTO NEW MARKETS

     The Company plans to expand into new geographic markets by acquiring and
affiliating with profitable radiology practices that have strong reputations
and competitive positions in their local markets.  The Company intends to focus
on markets where there are significant prospects for physician networking and
practice consolidation, high patient-provider ratios and favorable overall
economic conditions.  The Company intends to focus on acquiring and affiliating
with platform practices allowing the Company to pursue the  expansion strategy
discussed above.  The Company believes that it will be attractive to potential
Affiliated Practices because of its (i) exclusive focus on radiology, (ii)
governance structure which promotes physician input, (iii) service fee
structure which aligns the Company's revenue growth incentives with those of
the Affiliated Practices and (iv) transaction structure which permits
physicians to become





                                       89
<PAGE>   126
stockholders of the Company and further aligns the interests of the Company and
the Affiliated Practices.  The Company expects that its Affiliated Practices
will be instrumental in identifying potential acquisitions and affiliations
with future Affiliated Practices or ICs.

AFFILIATION STRUCTURE

     APPI was formed to provide physician practice management and
administrative services to radiology practices and to own, operate and manage
ICs.  The Company's business model is based on a "partnership" with its
Affiliated Practices in which the Company manages the non-medical functions of
the Affiliated Practices in a manner that promotes physician participation and
input in areas such as practice enhancement and operating efficiencies,
marketing and long-term strategy development.  The Company believes that its
partnering approach (i.e., shared ownership, economic interest and governance)
enables physicians to provide input in the management and affairs of their
practice and aligns the interests of physicians in the Affiliated Practices
with those of the Company in promoting practice growth and operating
efficiencies.  The Company believes its model will be attractive to potential
practice acquisition candidates.  For a discussion of the contractual
arrangements between the Company and its Affiliated Practices, see "APPI --
Operation, Management and Business Following the Merger and Exchanges --
Service Agreements."

     In connection with the Mergers and Exchanges, the Company will acquire
certain tangible and intangible assets and assume certain liabilities of the
Founding Affiliated Practices.  The Company will pay the purchase price for such
transactions in shares of its Common Stock and, to a lesser extent, cash.  At
the time of the  Mergers and Exchanges, the Company will enter into a 40-year
Service Agreement with each Founding Affiliated Practice pursuant to which the
Company will provide a wide range of management, administrative, technical and
non-medical services.  For providing services under the Service Agreement, the
Company will receive a fee which is structured to align the interests of the
Company and the Founding Affiliated Practices.  Additionally,  the Service
Agreements restrict the Founding Affiliated Practices from competing with the
Company and other Affiliated Practices within a specified geographic area during
the term of the Service Agreements and also require each Affiliated Practice to
obtain and enforce similar restrictive covenants with the full-time physicians
affiliated with their practices.  As part of its growth strategy, the Company
intends to acquire the assets of and enter into similar long-term Service
Agreements with additional radiology practices based on the partnership model it
has established with the Founding Affiliated Practices.

     The Company believes a shared governance approach is critical to the
long-term success of a physician practice management company.  While the
Company will have the primary responsibility for managing the non-medical
functions of its Affiliated Practices, it will operate within a governance
structure which promotes physician involvement in the direction and management
of the Affiliated Practices and the Company.  This will be accomplished by the
Company and each Affiliated Practice establishing a Joint Planning Board
consisting of three to six members.  The Joint Planning Boards will have
responsibility for (i) establishing payor contracting guidelines, (ii) making
recommendations with respect to operating budgets and capital expenditures and
(iii) developing marketing strategies and long-term objectives for their
respective practices.  The Company believes the Joint Planning Boards will
promote participation by physicians in the overall management of their
practices and serve as a means for the Company and its Affiliated Practices to
communicate effectively and exchange information.  In addition, the Company
intends to establish a Physician Advisory Board comprised of representatives of
the Founding Affiliated Practices, whose focus is to enhance the quality of
medical services provided by the Affiliated Practices.

OPERATIONS AND DEVELOPMENT

  GENERAL

     The Founding Affiliated Practices consist of seven radiology practices,
comprised of 218 radiologists, located in five states.  All of the Founding
Affiliated Practices provide professional services, which consist of the
supervision, performance and interpretation of radiological procedures in
hospitals, ICs or other settings.  As a result of the Mergers and Exchanges, the
Company will own and operate 54 ICs and operate and manage 11 additional ICs
through joint venture relationships.  In addition, the Founding Affiliated
Practices currently provide professional radiology services to 42 hospitals. In
the aggregate, the Founding Affiliated Practices will provide all subspecialty
diagnostic and interventional radiology and radiation oncology services.
Substantially all of the 218 radiologists are board certified.

     The number and type of modalities offered at the Company's owned, operated
or managed ICs are determined by the demand for such services within their
respective market areas.  Presently, 55 of these ICs offer multiple modalities
including various combinations of MRI, CT, mammography, ultrasound, nuclear
medicine, fluoroscopy and traditional radiography.  By offering a wide spectrum
of imaging modalities, the Company intends to market itself as a full-service
provider of diagnostic imaging services.  In addition to the ICs, the Founding
Affiliated Practices provide professional services to hospitals, hospital
outpatient facilities, physicians' offices, mobile imaging units and nursing
homes.





                                       90
<PAGE>   127
     The Company intends to expand its operations into new markets principally
through the acquisition of platform practices.  Prior to entering a new market,
the Company will consider various factors including the population,
demographics, market potential, competitive environment, degree of managed care
penetration, supply of radiologists, existing imaging services and general
economic conditions within the market.  The Company will seek to identify and
affiliate with group practices which have a significant market presence or
which the Company believes can achieve such a presence in the near term.  The
Company will identify potential acquisition candidates through a variety of
means, including targeted contacts of radiologists by the Company,
participation in professional conferences, referrals from Affiliated Practices
and direct inquiries by radiologists.

systems serviced by certain of the Founding Affiliated Practices and were
formed for the purpose of owning and operating ICs.  Professional services at
the joint venture ICs are performed by certain of the Founding Affiliated
Practices.

     The Founding Affiliated Practices were selected based on a variety of
factors, including: physician and practice credentials and reputation;
competitive market position; subspecialty mix of physicians; historical
financial performance and growth potential; and willingness to embrace the
Company's vision and philosophy regarding the provision of radiology services.

     The Company intends to provide its Affiliated Practices with capital for
(i) technological advances, including teleradiology and upgraded diagnostic
imaging equipment, (ii) information systems and (iii) additional ICs and
imaging equipment.  Set forth below are specific areas in which the Company
intends to provide capital resources to the Affiliated Practices:

 AREA OF EXPENDITURE                  OBJECTIVE

Advanced Imaging Equipment           Provision of high-quality imaging and
                                     image management, including

INFORMATION MANAGEMENT

     The Company believes that integrated radiology networks require extensive
information management systems to effectively manage operations, compete for
managed care contracts and achieve standardization and efficiencies of scale.
The Company intends to create a network infrastructure, including a Financial
Accounting System ("FAS") and Executive Information System ("EIS"), which may
utilize components of the Founding Affiliated Practices' existing information
systems.  The Company is also evaluating the feasibility of deploying other
standard information systems, including a managed care system and a radiology
information system.

     The Company intends to implement its initial information management plans
in two phases.  During the first phase, the Company intends to focus on
building a basic infrastructure.  Specifically, the Company intends to create a
network communications infrastructure and implement the FAS during the
remainder of 1997.  The network communications infrastructure will provide
access to the FAS and EIS, facilitate the gathering of key operational data and
increase internal communications capabilities through the enterprise-wide
deployment of standard office automation applications.  The Company expects
that the network infrastructure will provide the foundation for the sharing and
utilization of certain information among the Affiliated Practices and the
Company.  The network will be created with standard components to be managed
centrally in order to minimize the need for local information systems
personnel.

     The Company intends to deploy the FAS to facilitate timely and accurate
financial reporting throughout the Company.  Specifically, the Company intends
to deploy general ledger, accounts payable, payroll and materials management
systems at each of the Affiliated Practices.  The FAS will be designed to
facilitate the consistent, efficient reporting of financial information across
all practices using one standard chart of accounts with a single set of
accounting practices and financial controls.  The Company expects that the
deployment of the FAS will streamline and simplify the financial reporting
process and will provide a tool for managing practice efficiency benchmarks.

     During phase two, the Company expects to focus on assimilating and
analyzing data from its Affiliated Practices' disparate information systems.
In this phase, the Company intends to deploy an EIS that will facilitate the
management reporting of key operational data.  The Company anticipates that the
EIS will provide a repository to store pertinent encounter data and initially
will use the Affiliated Practices' practice management systems, radiology
information systems and the FAS as primary data sources.  It is anticipated
that the EIS will provide variance, utilization, reimbursement efficiency and
trend analysis reporting capabilities.  The Company believes that the EIS will
enable Affiliated Practices to enhance the quality of information, increase
revenue, improve operating efficiencies and more effectively control costs.
There can be no assurance that the Company will be able to implement the FAS or
EIS, that it will not encounter delays in  the implementation or that these
systems will produce the expected benefits.  See "Risk Factors -- Dependence on
Information Systems."

SERVICE AGREEMENTS

     Upon consummation of the Mergers and Exchanges, the Company will be a
party to a Service Agreement with each Founding Affiliated Practice under which
the Company will become the exclusive manager and administrator of non-medical
services relating to the operation of the Founding Affiliated Practice.  The
following summary of the Service Agreement is intended to be a brief
description of the standard form of the  Service Agreement that the Company
will be a party to with each Founding Affiliated Practice.  The Service
Agreements may vary from the description below depending on the requirements of
local regulations and negotiations with the individual Founding Affiliated
Practices.  The Company expects to enter into agreements with similar
provisions with Affiliated Practices in the future.

     The service fees payable to the Company by the Founding Affiliated
Practices under the Service Agreements vary based on the fair market value, as
determined in arms' length negotiations, for the nature and  scope of services
provided.  Such fees are payable monthly and consist of: (i) a fixed percentage
of the practice's revenue from physician and certain other medical services;
(ii) all or a substantial portion of the revenue derived from facility and
non-physician fees generated by ICs owned, operated or managed by the Company;
(iii) operating and non-operating expenses of the Founding Affiliated Practices
paid by the Company; and (iv) certain negotiated performance and other
adjustments.  In order to comply with local law, the service fees from two of
the Founding Affiliated Practices will be based on flat fees that are subject to
renegotiation on an annual basis.  See "APPI -- APPI Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Overview."

     Pursuant to the Service Agreement, the Company will, among other things:
(i) act as the exclusive manager and administrator of non- physician services
relating to the operation of the Founding Affiliated Practice, subject to
matters reserved to the Founding Affiliated Practice or referred to the Joint
Planning Board; (ii) aid in the billing of hospitals, insurance companies and
other third-party payors and collect on behalf of the Founding Affiliated
Practice the fees for professional medical and other services rendered by the
Founding Affiliated Practice; (iii) provide, as necessary, clerical,





                                       93
<PAGE>   130
accounting, purchasing, payroll, legal, bookkeeping and computer services and
personnel, information management, preparation of certain tax returns and
medical transcribing services; (iv) supervise and maintain custody of
substantially all files and records; (v) provide facilities for the Founding
Affiliated Practice; (vi) prepare, in consultation with the Joint Planning
Board and the Founding Affiliated Practice, all annual operating and capital
budgets; (vii) order and purchase inventory and supplies as necessary; (viii)
implement, in consultation with the Joint Planning Board and the Founding
Affiliated Practice, national and local public relations or advertising
programs; (ix) provide financial and business assistance in the negotiation,
establishment, supervision and maintenance of contracts and relationships with
managed care and other similar providers and payors; and (x) assist the
Founding Affiliated Practice with obtaining medical malpractice insurance for
its physicians and other medical professionals.

     The Service Agreements require the Company and each Founding Affiliated
Practice to establish a Joint Planning Board consisting of no less than three
or more than six members; two designees of the Company (each with one vote) and
no less than one or more than four designee(s) of the Founding Affiliated
Practice (representing two votes in the aggregate).  Each Joint Planning Board
will have responsibilities that include developing long-term strategic
objectives relating to practice expansion and payor contracting guidelines,
promoting practice efficiencies, recommending capital expenditures and
generally serving as a means by which the Company and each of the Founding
Affiliated Practices will communicate and exchange information.  The Company
intends to continue to establish Joint Planning Boards in the future, some of
which may be on a regional level.

     Under the Service Agreements, each Founding Affiliated Practice will
remain responsible for hiring and compensating its physicians and certain other
medical professionals, the licensing, credentialling and certification
necessary to conduct its practice and certain regulatory compliance.  The
Service Agreements with the Founding Affiliated Practices also contain
provisions whereby both the Company and each Founding Affiliated Practice have
agreed to certain restrictions on accepting or pursuing radiology opportunities
within a 15-mile radius (decreasing to ten miles upon the expiration of 12
months) of any of the Company's owned, operated or managed ICs at which the
Founding Affiliated Practice provides professional radiology services or any
hospital at which a Founding Affiliated Practice provides on-site professional
radiology services.  Each Service Agreement also restricts the applicable
Founding Affiliated Practice from competing with the Company and other
Affiliated Practices within a specified geographic area during the term of such
Service Agreement.  In addition, the Service Agreements require the Founding
Affiliated Practices to enter into and enforce agreements with the stockholders
and full-time radiologists at each Founding Affiliated Practice (subject to
certain exceptions) that include covenants not to compete with the Company for
a period of two years after termination of employment.

     The Service Agreements are for an initial term of 40 years, with automatic
extensions of five years unless notice of termination is given.  The Service
Agreements may be terminated by either party if (i) the other party (a) files a
petition in bankruptcy or other similar events occur or (b) defaults in the
performance of a material duty or obligation, which default continues for a
specified period after notice or (ii) an opinion is rendered by a law firm of
nationally-recognized expertise in health care law that a material term of the
Service Agreement is in violation of applicable law (or a court or regulatory
agency finds as such) and such violation cannot be cured.

     Each Service Agreement may also be terminated by the Company if the
Founding Affiliated Practice or a physician employee engages in conduct, or is
formally accused of conduct, for which the physician employee's license to
practice medicine reasonably would be expected to be subject to revocation or
suspension or is otherwise disciplined by any licensing, regulatory or
professional entity or institution, the result of any of which (in the absence
of termination of such physician or other action to monitor or cure such act or
conduct) does or reasonably would be expected to materially adversely affect
the Founding Affiliated Practice.  In addition, the Company may terminate each
Service Agreement with any Founding Affiliated Practice if, during the first
five years of the Service Agreement, more than 33 1/3% of the total number of
physicians employed or retained by such practice are no longer employed or
retained by such practice other than because of certain events, including
death, permanent disability, pre-qualified retirement or involuntary loss of
hospital contracts or privileges.

     Upon termination of a Service Agreement with a Founding Affiliated
Practice, depending upon the termination event, the Company may have the right
to require such Founding Affiliated Practice to purchase and assume, or the
Founding Affiliated Practice may have the right to require the Company to sell,
assign and transfer to it, the assets and related liabilities and obligations
associated with the professional and technical radiology services provided by
the Founding Affiliated Practice immediately prior to such termination.  The
purchase price for such assets, liabilities and obligations will be the lesser
of fair market value thereof or the return of the consideration received in the
Merger or Exchange as the case may be; provided, however, that the purchase
price shall not be less than the net book value of the assets being purchased.

PRACTICE MARKETING

     The Company intends to focus its marketing efforts on referring
physicians, hospitals and managed care organizations.  Prior to the
Mergers and Exchanges, the Founding Affiliated Practices' marketing efforts were
based primarily upon the professional reputations and individual efforts of
such practices and its radiologists.  The Company believes there is an
opportunity to capitalize on the professional reputations of the Founding
Affiliated Practices by applying professional sales and marketing techniques to
increase the Affiliated Practices' volume of business and expand the potential
geographic market for each Affiliated Practice beyond its local physician
community.

     In addition, the Company will seek to secure new contracts and expand
existing contracts with managed care organizations for the provision of
radiology services.  The Company is prepared to negotiate flexible arrangements
with managed care organizations on behalf of the Affiliated Practices.

GOVERNMENT REGULATION AND SUPERVISION

  GENERAL

     The health care industry is highly regulated, and there can be no
assurance that the regulatory environment in which the Company operates will
not change significantly in the future.  The ability of the Company to operate
profitably will depend in part upon the Company, the Affiliated Practices and
their affiliated physicians obtaining and maintaining all necessary licenses,
certificates of need and other approvals and operating in compliance with
applicable health care regulations.  The Company believes that health care
regulations will continue to change and, therefore, intends to monitor
developments in health care law and the Company expects to modify its
operations from time to time as the business and regulatory environment
changes.  There can be no assurance that the Company will be able to modify its
operations so as to address changes in the regulatory environment.

     Every state imposes licensing requirements on individual physicians and on
facilities operated, or services performed, by physicians.  In addition,
federal and state laws regulate HMOs and other managed care organizations with
which Affiliated Practices or their affiliated physicians may have contracts.
Many states require regulatory approval, including certificates of need, before
establishing or expanding certain types of health care facilities, offering
certain services or making expenditures in excess of statutory thresholds for
health care equipment, facilities or programs.  In connection with the
expansion of existing operations and the entry into new markets, the Company,
the Affiliated Practices or their affiliated physicians may become subject to
additional regulation.

     In addition to existing government health care regulation, there have been
numerous initiatives on the federal and state levels for comprehensive reforms
affecting the payment for and availability of health care services.  The
Company believes that such initiatives will continue during the foreseeable
future.  Certain aspects of these reforms as proposed in the past, such as
further reductions in Medicare and Medicaid payments and additional
prohibitions on physician ownership, directly or indirectly, of facilities to
which they refer patients, if adopted, could adversely affect the Company.
Concern about the potential effects of such reform measures has contributed to
the volatility of stock prices of many companies in health care and related
industries and may similarly affect the market price of the Common Stock.

     Federal regulatory and law enforcement authorities have recently increased
enforcement activities with respect to Medicare and Medicaid fraud and abuse
regulations and other reimbursement laws and rules, including laws and
regulations that govern the Company's activities.  There can be no assurance
that the Company's activities will not be investigated, that claims will not be
made against the Company or that these increased enforcement activities will
not directly or indirectly have an adverse effect on the Company's  business,
financial condition and results of operations.

  FEE-SPLITTING; CORPORATE PRACTICE OF MEDICINE

     The laws of many states (including each of the states in which the Founding
Affiliated Practices are located) prohibit physicians from splitting fees with
non-physicians and prohibit non-physician entities from practicing medicine.
These laws vary from state to state and are enforced by the courts and by
regulatory authorities with broad discretion.  Although the Company believes its
proposed operating structures and methods as described in this Prospectus/Joint
Proxy Statement will be in compliance with existing applicable laws, the
Company's business operations have not been the subject of judicial or
regulatory interpretation.  There can be no assurance that a review of the
Company's business by courts or regulatory authorities will not result in
determinations that could adversely affect the operations of the Company or that
the health care regulatory environment will not change so as to restrict the
Company's planned operations and expansion.  In addition, the regulatory
framework of certain jurisdictions may limit the Company's expansion into such
jurisdictions if the Company is unable to modify its operational structure to
conform with such regulatory framework.





                                       95
<PAGE>   132
  MEDICARE PHYSICIAN PAYMENT SYSTEM

     The Company believes that regulatory trends in cost containment will
continue to result in a reduction from historical levels in per- patient
revenue for medical practices.  The federal government has implemented, through
the Medicare program, the RBRVS payment methodology for physician services.
The RBRVS is a fee schedule that, except for certain geographical and other
adjustments, pays similarly situated physicians the same amount for the same
services.  The RBRVS is adjusted each year and is subject to increases or
decreases at the discretion of Congress.  To date, the implementation of the
RBRVS has reduced payment rates for certain of the procedures historically
provided by the Founding Affiliated Practices.  There can be no assurance that
any reduced operating margins could be offset by the Company through cost
reductions, increased volume, the introduction of additional procedures or
otherwise.

     Rates paid by non-governmental insurers, including those that provide
Medicare supplemental insurance, are based on established physician and
hospital charges and are generally higher than Medicare payment rates.  A
change in the makeup of the patient mix of the medical practices that results
in a decrease in patients covered by private insurance plans could adversely
affect the Company's revenue and income.

  MEDICARE AND MEDICAID FRAUD AND ABUSE

     Federal law prohibits the offer, payment, solicitation or receipt of any
form of remuneration in return for, or in order to induce, (i) the referral of
a person, (ii) the furnishing or arranging for the furnishing of items or
services reimbursable under Medicare or Medicaid programs or (iii) the
purchase, lease or order or arranging or recommending purchasing, leasing or
ordering of any item or service reimbursable under Medicare or Medicaid.
Pursuant to this anti-kickback law, the federal government has recently
announced a policy of increased scrutiny of joint ventures and other
transactions among health care providers in an effort to reduce potential fraud
and abuse relating to Medicare costs.  The applicability of these provisions to
many business transactions in the health care industry has not yet been subject
to judicial and regulatory interpretation.  Noncompliance with the federal
anti-kickback legislation can result in exclusion from Medicare and Medicaid
programs and civil and criminal penalties.

     The Company believes that although it will receive fees under the Service
Agreements for management and administrative services, it is not in a position
to make or influence referrals of patients or services reimbursed under
Medicare or Medicaid programs to Affiliated Practices or their affiliated
physicians, or to receive such referrals.  Such service fees are intended by
the Company to be consistent with fair market value in arms' length
transactions for the nature and amount of management and administrative
services rendered.  For these reasons, the Company does not believe that fees
payable to it would be viewed as remuneration for referring or influencing
referrals of patients or services covered by such programs as prohibited by
statute.  If, however, the Company is deemed to be in a position to make,
influence or receive referrals from or to physicians, or the Company is deemed
to be a provider under the Medicare or Medicaid programs, the operations of the
Company could be subject to scrutiny under federal and state anti-kickback and
anti-referral laws and the Company's operations could be materially and
adversely affected.

     Significant prohibitions against physician referrals have been enacted by
Congress.  These prohibitions, commonly known as "Stark II," amended prior
physician self-referral legislation known as "Stark I" by dramatically
enlarging the field of physician-owned or physician- interested entities to
which the referral prohibitions apply.  Stark II prohibits a physician from
referring Medicare or Medicaid patients to an entity providing "designated
health services" in which the physician has an ownership or investment
interest, or with which the physician has entered into a compensation
arrangement.  The penalties for violating Stark II include a prohibition on
payment by these government programs and civil penalties of as much as $15,000
for each violative referral and $100,000 for participation in a "circumvention
scheme."  The Company believes that although it will receive fees under the
Service Agreements for management and administrative services, it is not in a
position to make or influence referrals of patients.  To the extent that the
Company or any Affiliated Practice is deemed to be subject to the prohibitions
contained in Stark II for services, the Company believes its activities fall
within the permissible activities defined in Stark II.

     In addition, the Company believes that the methods used to acquire the
assets of existing practices do not violate anti-kickback and anti- referral
laws and regulations.  Specifically, the Company believes the consideration
paid by the Company to physicians to acquire the tangible and intangible assets
associated with their practices is consistent with fair market value in arms'
length transactions and not intended to induce the referral of patients.
Should this practice be deemed to constitute an arrangement designed to induce
the referral of Medicare or Medicaid patients, then the Company's acquisitions
could be viewed as possibly violating anti-kickback and anti-referral laws and
regulations.  A determination of liability under any such laws could have a
material adverse effect on the Company's business, financial condition and
results of operations.

<PAGE>   133
  INSURANCE LAWS AND REGULATION

     Certain states have enacted statutes or adopted regulations affecting risk
assumption in the health care industry, including statutes and regulations that
subject any physician or physician network engaged in risk-based contracting to
applicable insurance laws and regulations, which may include, among other
things, laws and regulations providing for minimum capital requirements and
other safety and soundness requirements.  The Company believes that it and the
Affiliated Practices are currently in compliance with such insurance laws and
regulations.  However, implementation of additional regulations or compliance
requirements could result in substantial costs to the Company and the
Affiliated Practices.  The inability to enter into capitated or other
risk-sharing arrangements or the cost of complying with certain applicable laws
that would permit expansion of the Company's risk-based contracting activities
could have a material adverse effect on the Company's business, financial
condition and results of operations.

COMPETITION

     The Affiliated Practices and the Company's owned, operated or managed ICs
will compete with local radiology and imaging service providers.  The Company
believes that changes in governmental, private reimbursement policies and other
factors have resulted in increased competition among providers for medical
services to consumers and that cost, accessibility, quality and scope of
services provided are the principal factors that affect competition.  There can
be no assurance that the Affiliated Practices and the Company's owned, operated
or managed ICs will be able to compete effectively in the markets that they
serve, which inability to compete could adversely affect the Company.

     The Company believes that the current trends in the hospital industry have
resulted in increased competition by radiology groups for hospital contracts.
Each of the Founding Affiliated Practices provides radiology services to
hospitals.  These relationships can be affected through competition with other
radiology groups, the outsourcing of the radiology and imaging functions within
the hospital or closure of the hospital due to consolidation or financial
instability.  There can be no assurance that each of the Founding Affiliated
Practices will maintain its current hospital relationships and be able to renew
or extend its current arrangements under favorable terms or effectively compete
for new relationships.

     The Company is under competitive pressures for the acquisition and
retention of the assets of, and the provision of management, technical and
administrative services to, additional radiology practices, MSOs and ICs.
There are a number of publicly-traded companies focused on owning or managing
ICs.  The Company is aware of two privately-held physician practice management
companies focused on professional and technical radiology services.  Several
companies, both publicly and privately held, that have established operating
histories and, in some instances, greater resources than the Company are
pursuing the acquisition of general and specialty physician practices and the
management of such practices.  Additionally, some hospitals, clinics, health
care companies, HMOs and insurance companies engage in activities similar to
those of the Company.  There can be no assurance that the Company will be able
to compete effectively with such competitors for the acquisition of, or
affiliation with, radiology practices, that additional competitors will not
enter the market, that such competition will not make it more difficult or
expensive to acquire the assets of, and provide management, administrative,
technical and non-medical services to, radiology practices on terms beneficial
to the Company or that competitive pressures will not otherwise adversely
affect the Company.

FACILITIES AND EMPLOYEES

     The Company's corporate headquarters are located at 2301 NationsBank
Plaza, 901 Main Street, Dallas, Texas 75202, in approximately 10,500 square
feet occupied under a lease which expires on September 30, 2001.  As of May 31,
1997, the Company had 17 employees and, upon consummation of the
Mergers and Exchanges, the Company expects that it will have approximately 1,100
employees, of which approximately 30 will be employed at the Company's
headquarters and regional offices and the remainder will be employed at the
Founding Affiliated Practices.  The Company believes that its relationship with
its employees is good.  See "APPI -- Operation, Management and Business
Following the Mergers and Exchanges -- Operations and Development."

CORPORATE LIABILITY AND INSURANCE

     The Founding Affiliated Practices maintain professional liability insurance
coverage primarily on a claims made basis.  Such insurance provides coverage for
claims asserted when the policy is in effect regardless of when the events that
caused the claim occurred.  As a result of the Mergers and Exchanges, the
Company will in some cases succeed to certain liabilities of the Founding
Affiliated Practices.  Therefore, claims may be asserted after the Mergers and
Exchanges against the Company for events which occurred prior to the Mergers and
Exchanges.  Following the Mergers and Exchanges, the Company and the Affiliated
Practices intend to maintain insurance coverage similar to the coverage
previously maintained by the Founding Affiliated Practices.  On May 22, 1997,
the state of Texas adopted legislation that permits injured patients to sue
health insurance carriers, health maintenance organizations and other managed
care entities for medical





                                       97
<PAGE>   134
malpractice.  The statute becomes effective September 1, 1997.  There can be no
assurance that this legislation will not increase the cost of liability
insurance to the Company for services provided in Texas or any other states in
which the Company does business if similar legislation is adopted in those
states.

     The provision of medical services entails an inherent risk of professional
malpractice and other similar claims.  The Company's intent is to not influence
or control the practice of medicine by physicians or have responsibility for
compliance with certain regulatory and other requirements directly applicable
to physicians and physician groups.  As a result of the relationship between
the Company and the Affiliated Practices, however, the Company may become
subject to medical malpractice actions under various theories, including
successor liability.  There can be no assurance that claims, suits or
complaints relating to services provided by Affiliated Practices will not be
asserted against the Company in the future.  The Company expects to maintain
insurance coverage that it believes will be adequate.  The Company anticipates
that such insurance will extend to professional liability claims that may be
asserted against employees of the Company that work on site at Affiliated
Practice locations.  In addition, pursuant to the Service Agreements, the
Founding Affiliated Practices are required (and the Company intends to require
any other Affiliated Practices) to maintain comprehensive professional
liability insurance.  The availability and cost of such insurance is affected
by various factors, many of which are beyond the control of the Company and
Affiliated Practices.  The cost of such insurance to the Company and the
Affiliated Practices may have an adverse effect on the Company's operations.
In addition, successful malpractice or other claims asserted against Affiliated
Practices or the Company that exceed applicable policy limits could have a
material adverse effect on the Company.

     In connection with the Mergers and Exchanges, the security holders of the
Founding Affiliated Practices have agreed to indemnify the Company for certain
claims.  There can be no assurance that the Company will be able to receive
payments under any such indemnity agreements or that the failure to fully
recover such amounts will not have a material adverse effect on the Company's
business, financial condition or results of operations.

LEGAL PROCEEDINGS

     The Company is not a party to any suits or complaints relating to services
provided by the Company or the Founding Affiliated Practices, although there
can be no assurances that claims will not be asserted against the Company in
the future.  The Company will become subject to certain pending claims as the
result of successor liability in connection with the Mergers and Exchanges;
however, the Company believes that the ultimate resolution of such claims will
not have a material adverse effect on the business, financial condition or
results of operations of the Company.

APPI MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS

     The following discussion relates to the historical and pro forma combined
operations of APPI, the entity whose Common Stock is being issued in connection
with the Mergers and Exchanges and the Initial Public Offering. The following
discussion of the pro forma combined results of operations and financial
position of the Company should be read in conjunction with the financial
statements of APPI and the Company's unaudited pro forma combined financial
statements and notes thereto appearing elsewhere in this Prospectus.  The pro
forma financial results of the Company included herein cover periods when the
Founding Affiliated Practices and APPI were not under common control or
management and, therefore, may not be indicative of the Company's future
financial or operating results.  There can be no assurance that the Company will
be profitable on a quarterly or annual basis in the future.

  OVERVIEW

     APPI has conducted no significant operations to date but will be
acquiring, in connection with the Mergers, Exchanges and Reorganizations and
the Initial Public Offering, tangible and intangible assets and liabilities of,
and entering into Service Agreements with, the Founding Affiliated Practices.
Through the Service Agreements, the Company will be providing management,
administrative, technical and non-medical services to the Affiliated Practices
in return for service fees.  The service fees represent the physician groups
revenue, net less amounts retained by physician groups.  Physician groups
revenue, net consists of the revenue of the Affiliated Practices reported at
the estimated realizable amounts from patients, third-party payors and others
for services rendered, net of contractual and other adjustments.  The service
fees payable to the Company by the Affiliated Practices under the Service
Agreements vary based on the fair market value, as determined in arms' length
negotiations, and the nature and extent of services provided.  Such fees are
payable monthly and consist of the following: (i) a percentage of the revenue
relating to physician services and certain other medical services; (ii) all or
a substantial portion of the revenue derived from facility





                                       99

<PAGE>   136
and non-physician fees generated by ICs owned, operated or managed by the
Company; (iii) operating and non-operating expenses of the Founding Affiliated
Practices paid by the Company pursuant to the Service Agreements; and (iv)
certain negotiated performance and other adjustments.  The service fees for two
practices are subject to state law requiring flat fees that are subject to
renegotiation on an annual basis.  In addition, the Company receives income
from joint ventures in which the Affiliated Practices hold minority interests.
The joint ventures are accounted for under the equity method of accounting.

     The expenses incurred by the Company associated with its obligations under
the Service Agreements are generally the same as the operating costs and
expenses that would have otherwise been incurred by the Founding Affiliated
Practices, including: the salaries, wages and benefits of non-physician
personnel; medical supplies expenses involved in administering technical aspects
of the practices; the office (general and administrative) expenses of the
practices; depreciation and amortization of assets acquired from the Affiliated
Practices; and certain other items.  As further described in "APPI -- Operation,
Management and Business Following the Mergers and Exchanges -- Business
Strategy," the Company intends to implement measures designed to reduce these
operating costs and expenses through purchase discounts, economies of scale,
benchmarking programs and more effective equipment utilization.  In addition to
the operating costs and expenses discussed above, the Company will be incurring
additional personnel and administrative expenses in connection with establishing
and maintaining corporate and regional offices, which will provide management,
administrative, marketing and acquisition services.

     An integral part of the Company's business strategy is to grow through
acquisitions and to expand the Affiliated Practices.  Although the Company is
currently engaged in discussions with several such potential acquisition
candidates, except as disclosed in this Prospectus/Joint Proxy Statement, the
Company has not entered into any letters of intent or definitive purchase
agreements with respect to any such acquisitions.  No assurance can be provided
that any such acquisitions will be consummated.

  RESULTS OF OPERATIONS

     APPI has conducted no significant operations to date and will not conduct
significant operations until the Mergers and Exchanges and the Initial Public
Offering are completed.  APPI has incurred and continues to incur various
legal, accounting, travel and marketing costs in connection with the Mergers
and Exchanges and the Initial Public Offering.  As of March 31, 1997, such
expenses had been funded primarily by the proceeds received from the issuance
of $3.5 million in Convertible Notes.  In addition, during 1996, APPI borrowed
$0.4 million in the form of notes from its stockholders.  As of March 31, 1997,
these notes had been fully paid.

     APPI has recorded a full valuation allowance against its deferred tax
assets because of its current financial condition, its limited operating
history and its operating losses recorded to date.  If the Company does achieve
profitability in the future, the valuation allowance will be reduced by a
credit to income.

  PRO FORMA

     As discussed in the notes to the unaudited pro forma combined statement of
operations, the revenue of the Company will consist primarily of fees under the
Service Agreements.  The revenue included in the pro forma financial statements
are those that would have been earned based on the operating results of the
Founding Affiliated Practices in 1996 and for the three months ended March 31,
1997 assuming that the Mergers and Exchanges and the Initial Public Offering
had been completed as of January 1, 1996.  The pro forma service fee revenue of
$89.6 million for the year ended December 31, 1996 and $24.8 million for the
three months ended March 31, 1997 is based on the service fees that would have
been payable had the Service Agreements been in effect for such periods.

     The total pro forma operating expenses for the year ended December 31,
1996 and for the three months ended March 31, 1997 do not reflect cost
reductions which the Company intends to seek or the addition of corporate costs
associated with the Company's anticipated expanded infrastructure.

     Pro forma income taxes assume that the Company had operated as a taxpaying
entity for the year ended December 31, 1996 and for the three months ended
March 31, 1997, subject to an effective combined federal and state income tax
rate of 40%.

  LIQUIDITY AND CAPITAL RESOURCES

     If the Mergers and Exchanges and the Initial Public Offering had occurred
on March 31, 1997, the Company would have had pro forma working capital of $10.4
million (assuming an Initial Offering Price of $15.00 per share and after giving
effect to the use of proceeds from the Initial Public Offering).





                                      100
<PAGE>   137
     The Company anticipates making capital expenditures during the remainder
of 1997 of approximately $7.0 million, primarily for the purchase of imaging
and teleradiology equipment.  In addition to these capital expenditures, the
Company is working to establish relationships with third-party vendors
regarding the potential purchase and implementation of management information
systems that could involve additional expenditures of approximately $2.4
million during the remainder of 1997 and thereafter.  The net cash proceeds of
the Initial Public Offering combined with cash flow from operations, are
expected by the Company to be sufficient to fund anticipated capital
expenditures and ongoing operations of the Company through the end of 1997.
The Company also expects to make acquisitions of the assets of practices during
1997 that will involve the use of cash and Common Stock.  The Company has
obtained a commitment letter for a $100 million credit facility from GE
Capital Corporation, subject to the negotiation of definitive documentation,
due diligence and certain other conditions.  The Company anticipates that such
credit facility will be effective concurrently with the closing of the Initial
Public Offering and, when combined with the Company's cash from operations,
will be utilized for capital expenditures and other general corporate purposes,
including future acquisitions.

     On or after the Effective Date of the Initial Public Offering, the Company
intends to call the Convertible Notes for redemption.  The Company plans to
call the Convertible Notes for redemption at the earliest practicable date.
Upon the call, the Convertible Notes may, at the election of the noteholders of
at least 50% of the outstanding principal amount, be converted into shares of
Common Stock at a conversion price of $8.00 per share.

STOCK OPTION PLAN

     In May 1996, the Board of Directors adopted, and the stockholders of the
Company subsequently approved, the Company's 1996 Stock Option Plan (the
"Plan").  The purpose of the Plan is to provide directors, key employees and
certain advisors with additional incentives by increasing their proprietary
interest in the Company.  Under the Plan, the aggregate amount of APPI Common
Stock with respect to which options may be granted may not exceed 3,000,000
shares. The Plan is intended to qualify for favorable treatment under Section 16
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
pursuant to Rule 16b-3 promulgated thereunder ("Rule 16b-3").

     The Plan provides for the grant of incentive stock options ("ISOs") as
defined in Section 422 of the Internal Revenue Code, and non- qualified stock
options (collectively, "Awards").  Following the consummation of the Initial
Public Offering, the Plan will be administered by the Compensation and Stock
Plan Administration Committee, which will be comprised of two or more
non-employee directors who are "disinterested" within the meaning of Rule 16b-3
(the "Committee").  Prior to the consummation of the Initial Public Offering,
the Plan has been administered by the Company's full Board of Directors.  The
Board of Directors currently has, and the Committee will have, following
consummation of the Initial Public Offering, subject to the terms of the Plan,
the sole authority to grant Awards under the Plan, to construe and interpret
the Plan and to make all other determinations and take any and all actions
necessary or advisable for the administration of the Plan.

     All of the Company's employees, non-employee directors and advisors are
eligible to receive Awards under the Plan, but only employees of the Company
are eligible to receive ISOs.  Options will be exercisable during the period
specified in each option agreement and will generally be exercisable in
installments pursuant to a vesting schedule to be designated by the Committee.
Notwithstanding the provisions of any option agreement, options will become
immediately exercisable in the event of a "change in control" (as defined in
the Plan) of the Company and in the event of certain mergers and
reorganizations of the Company.  No option will remain exercisable later than
ten years after the date of grant (or five years from the date of grant in the
case of ISOs granted to holders of more than 10% of the Common Stock).

     The exercise price for ISOs granted under the Plan may be no less than the
fair market value of the Common Stock on the date of grant (110% of fair market
value in the case of ISOs granted to holders of more than 10% of the Company's
Common Stock).  The exercise price for nonqualified options granted under the
Plan may be no less than 85% of the fair market value of the APPI Common Stock
on the date of grant.

     The Plan provides for automatic grants of non-qualified options to purchase
30,000 shares of Common Stock to non-employee directors at the time a director
is first elected or appointed as a non-employee director to vest over a term of
36 months, provided that such person continues to serve as a director of the
Company.  In addition, upon expiration of the 36-month period following the
initial option grant to such non- employee director, such non-employee director
shall automatically be granted at each annual stockholders meeting a
non-qualified option to purchase 10,000 shares of APPI Common Stock vesting over
a term of 12 months.  Each such option entitles the director to purchase shares
of APPI Common Stock at an exercise price equal to the fair market value of the
APPI Common Stock on the automatic grant date.  Each option shall have a ten
year term measured from the automatic grant date.

     The Plan will also permit the Company to grant stock options to advisors
and consultants of the Company who are employed as physicians of an Affiliated
Practice.  Generally, such options will expire upon the termination of
employment with the Affiliated Practice or the advisory or consultant
relationship with the Company or on the day prior to the tenth anniversary of
the date of grant, whichever occurs first.

     The Company anticipates that upon the consummation of the Initial Public
Offering it will have outstanding options to purchase a total of approximately
1,735,000 shares of Common Stock to its employees, directors and consultants.
Generally, the outstanding options are exercisable based on a monthly vesting
schedule over 60 months.  The Company anticipates that it will issue additional
options concurrently with or shortly following consummation of the Initial
Public Offering.  Such options will be exercisable at the fair market value of
the Common Stock on the date of grant.

- -------------
</TABLE>

     (1)  All options were granted at fair market value at the date of grant, as
          determined by the Company's Board of Directors.  These options vest
          monthly over a five-year period.

     (2)  The option exercise price may be paid in shares of Common Stock owned
          by the executive officer, in cash, or in any other form of valid
          consideration as determined by the Compensation and Stock Plan
          Administration Committee in its discretion.

     (3)  The dollar amounts in these columns represent the potential realizable
          value that might be realized upon exercise of the options immediately
          prior to the expiration of their term, assuming that the market price
          of Common Stock appreciates in value from the date of grant at assumed
          annual rates of 5% and 10%.  These assumed rates of appreciation are
          prescribed by the rules and regulations of the SEC, and therefore are
          not intended to forecast possible future appreciation, if any, of the
          price of the APPI Common Stock.  These numbers do not take into
          account provisions of certain options providing for termination of the
          option following termination of employment, nontransferability or
          vesting over periods.

     (4)  Upon consummation of the Initial Public Offering, this option becomes
          exercisable with respect to the greater of 50% of the shares covered
          thereby or the actual number of shares that have vested.  The
          remainder of the shares underlying the option become exercisable in
          equal monthly installments over the remaining vesting period.  These
          numbers do not take into account provisions of certain options
          providing for termination of the option following termination of
          employment, nontransferability or vesting over periods.

     (5)  As to 200,000 shares, upon consummation of the Initial Public
          Offering, this option becomes exercisable with respect to the greater
          of 100,000 shares or the actual number of shares that have vested, and
          the remainder of such shares become exercisable in equal monthly
          installments over the remaining vesting period.  As to 30,000 shares,
          10,000 shares become exercisable on the first anniversary of the date
          of grant and the remaining shares become exercisable in 24 equal
          monthly installments over the next 24 months.  These numbers do not
          take into account provisions of certain options providing for
          termination of the option following termination of consulting
          relationships, cessation of services as a director of the Company or
          nontransferability.

     (6)  Upon consummation of the Initial Public Offering, this option becomes
          exercisable with respect to the greater of 25% of the shares covered
          thereby or the actual number of shares that have vested upon
          consummation of the Initial Public Offering.  The remainder of the
          shares underlying the option become exercisable in equal monthly
          installments over the remaining vesting period. These numbers do not
          take into account provisions of certain options providing for
          termination of the option following termination of employment,
          nontransferability or vesting over periods.

CASH BONUS PROGRAM

     In April 1997, the Board of Directors adopted, and the stockholders of the
Company subsequently approved, the Company's Cash Bonus Program (the
"Program").  The purpose of the Program is to establish a bonus plan pursuant
to which eligible employees will be entitled to receive cash bonuses based on
the performance of the Company.  Those employees eligible to receive cash
bonuses under the Program include the executive officers of the Company and
certain key employees whose responsibilities and activities are closely
connected to the Company's overall performance.

     Under the Program, cash bonuses are calculated as a percentage of each
eligible employee's base salary, with such percentage being determined based
upon the annual increase in the Company's earnings per share.  In addition,
each eligible employee may receive a cash bonus based upon the achievement of
certain individual objectives and the Company's overall performance.  The
Program will become effective upon consummation of the Initial Public Offering
and will be administered by the Compensation and Stock Plan Administration

wages and expense reimbursements. Such employment agreements provide that in
the event such employee's employment terminates following a change in control
transaction (as defined in such employment agreements) of the Company, the

will be minimal, will be approved by a majority of the disinterested members of
the Board of Directors and will be made on terms no less favorable to the
Company than could be obtained from unaffiliated third parties.  The Company
does not intend to make any loans to, or incur any indebtedness to, any of its
executive officers or directors.

                               ADVANCED RADIOLOGY

                       OPERATION, MANAGEMENT AND BUSINESS

GENERAL

     Advanced Radiology operates a professional medical radiology practice
formed in July 1997 that was organized as a Maryland professional association.
Advanced Radiology represents the merger of seven radiology practices. Advanced
Radiology provides two types of services: (1) professional diagnostic and
interpretive services ("Professional Services") and (2) imaging services
including x-ray, fluoroscopy, computed tomography, magnetic resonance imaging,
mammography and ultrasound ("Imaging Services"), both of which are reimbursed on
a prepaid or fee-for-service basis.  Advanced Radiology operates in the Greater
Baltimore Metropolitan Area (the "Advanced Service Area").  Advanced Radiology
contracts directly with hospitals, health plans, physician groups and insurance
carriers to provide Professional Services and Imaging Services to enrollees and
patients.  Through contracts with various health plans, physician groups and
hospitals, Advanced provided approximately 1 million patient examinations during
1996.  Advanced Radiology operates 23 Professional Service locations and ten
hospital-based locations within the Service Area.

     Advanced Radiology owns all of the membership interests of Advanced
Radiology, LLC.  Advanced Radiology, LLC owns a 75.353% interest in MRI at St.
Joseph Medical Center, LLC, a 50% interest in two partnerships, Franklin
Imaging Joint Venture and Advanced Imaging of Carroll County limited
partnership, each of which perform radiology and imaging healthcare services.
Advanced Radiology, LLC owns 66 2/3% of the common stock of Advanced Medical
Imaging, Inc. which enters into and administers managed care contracts for
radiology services.  Advanced Radiology, LLC also is a 50% member in Poole Road
Imaging, LLC and Health Systems Imaging, LLC, each of which owns and operates
diagnostic imaging centers.

STRATEGY

     Advanced Radiology's strategy is to continue penetration of its existing
markets, expand into other markets, create strategic alliances with hospitals
and other Imaging Service providers, increase the operational efficiency of,
and reduce costs associated with, the Advanced Radiology operations.

     The future growth of Advanced Radiology in its existing markets is
dependent in part on the continued increase of health plan enrollees and
patients using Advanced Radiology for Professional Services.  This growth may
come, with respect to Professional Services, from the development or
acquisition of additional facilities and the development of affiliations with
medical groups serving enrollees or patients in existing markets, increased
enrollment in health plans currently contracting with Advanced Radiology and
its medical affiliates, and contracts with new health plans or hospitals.  It
actively recruits new providers and seeks to enter into new hospital-based or
managed care contracts in order to enlarge the potential patient base in its
service areas.

     Advanced Radiology's principal strategy for expanding into new markets is
through acquisitions (through merger, purchase, or otherwise) of medical
groups.  Advanced Radiology generally seeks providers that have established
reputations for providing quality medical care.

GOVERNMENT REGULATION

     Advanced Radiology is subject to federal and state laws regulating the
relationships among providers of health care services, physicians and other
clinicians.  These laws include the fraud and abuse provisions of the Medicare
and Medicaid statutes, which prohibit the solicitation, payment, receipt or
offering of any direct or indirect remuneration for the referral of Medicare or
Medicaid patients or for the recommending, leasing, arranging, ordering or
purchasing of Medicare or Medicaid covered services.  Other laws impose
significant penalties for false or improper billings for physician services and
impose restrictions on physician referrals for designated health services
reimbursable under the Medicare or Medicaid programs to entities with which they
have financial relationships. While Advanced Radiology believes it is in
material compliance with applicable laws, there is no assurance that its present
or past operations will not be subjected to scrutiny or legal challenges.

SERVICES PROVIDED

     Advanced Radiology operates a total of 33 facilities that are staffed by
either Professional Service providers or Imaging Service providers.  As of
April 30, 1997, Advanced Radiology employed 87 Professional Service providers
and 212 Imaging Service providers.

     Advanced Radiology provides approximately 15% of its Professional Service
and Imaging Service under capitated contracts and 85% under fee-for-service or
hospital contracts.  Under capitated contracts, Advanced Radiology provides or
arranges for all physician services and Advanced Radiology receives a fixed
monthly capitation payment from health plans for each member who utilize an
Advanced Radiology physician.

     During 1996, approximately 1 million patient examinations were performed
by Advanced Radiology.  Advanced Radiology is under contract with the following
hospitals and with more than 100 health plans:  Carroll County General
Hospital, Church Home Hospital, Franklin Square Hospital, Greater Baltimore
Medical Center, Harbor Hospital Medical Center, Liberty Medical Center, North
Arundel Hospital, Northwest Hospital Center, St. Agnes Hospital and St. Joseph
Hospital.

     Advanced conducts an extensive and ongoing utilization review program
under the direction of a committee of physician members, which program includes
both prospective and retrospective analysis of utilization.

COMPETITION

     The health care industry is highly competitive.  The industry is also
subject to continuing changes in the services that are provided and how
providers are selected and paid.

EMPLOYEES

  PROFESSIONAL SERVICE PROVIDER EMPLOYEES

     Advanced Radiology physicians enter into employment contracts.  These
contracts offer a specified guaranteed salary and an incentive bonus.
Physicians are also eligible to receive benefits such as health, dental and
life insurance, paid time off and an allowance for continuing medical education
and other professional expenses.  Advanced Radiology, as of April 30, 1997,
employed 87 physicians (79 full-time and 8 part-time).

  IMAGING SERVICE PROVIDER EMPLOYEES

     As of April 30, 1997, Advanced employed 212 imaging service providers (126
full-time and 86 part-time).

  NON-PROVIDER EMPLOYEES

     As of April 30, 1997, Advanced Radiology had approximately 518
non-physician employees.  None of Advanced Radiology's employees are represented
by a labor union.  Management of Advanced Radiology believes its employee
relations are good.

INSURANCE

     Advanced Radiology maintains insurance coverage for various perils and
from various carriers.  In addition to property and casualty, worker's
compensation, directors and officers liability and other coverage Advanced
Radiology believes to be customary and reasonable for a business of its kind,
Advanced Radiology maintains general and professional liability insurance
policies (the "Liability Policies") with ITT Hartford, Standard Security Life,
Medical Mutual Liability, Royal Insurance and Mid-Atlantic Medical.  Each
professional of Advanced Radiology, at each location, is covered under the
Liability Policies.

PROPERTIES AND FACILITIES

     Advanced Radiology leases approximately 32 facilities.  The real property
leases range from 1,000 square feet to 38,000 square feet.  Advanced Radiology

INFORMATION SYSTEMS

     Advanced Radiology believes that the effective analysis of medical and
financial data is essential in today's managed care environment.  Accordingly,
Advanced Radiology is committed to the development of a fully-integrated
management information system ("MIS") for practice management.  Advanced
Radiology's MIS capabilities include medical charting and tracking analysis of
practice management information and financial data.  Practice management
functions of the current MIS include registration, centralized scheduling and
appointments, electronic claims submission and remittance.  Managed care
functions include referrals, eligibility, determination, claim management and
payment functions.

TELERADIOLOGY

     Advanced owns and operates a state-of-the-art teleradiology system which
currently allows for contemporaneous interpretation of all of the images
obtained in its ten hospital emergency rooms during night-time hours (10:00
p.m. to 7:00 a.m.).  Approximately 50,000 exams have been interpreted using
this system since its installation in September 1996.  This system is one of
the largest operating teleradiology systems in the United States.

LEGAL PROCEEDINGS

     Advanced Radiology is engaged in the defense of lawsuits arising in the
ordinary course and conduct of its business, including an employee
discrimination suit involving two former physicians.  Advanced Radiology
believes that such actions will not have a material adverse effect on Advanced
Radiology.

           ADVANCED RADIOLOGY MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion relates to the historical operations of Advanced
and should be read in conjunction with the audited financial statements of
Advanced and the notes thereto appearing elsewhere in this Prospectus/Joint
Proxy Statement. For purposes of the following discussion, medical service
revenue, net represents the estimated realizable amount to be received from
patients, third party payors and others for the provision of medical services.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1997 AS COMPARED TO THREE MONTHS ENDED MARCH 31,
1996

     Medical service revenue, net increased by $3.7 million or 31% to $15.7
million for the three month period ended March 31, 1997 from $12.0 million for
the three month period ended March 31, 1996.  This increase was attributable to
the addition of two new radiology groups in April 1996 and January 1997, new
hospital management contracts and an increase in procedures and/or covered
lives at existing facilities.

     Costs of affiliated physician services of $1.1 million (7% of medical
service revenue, net) and $0.1 million (1% of medical service revenue, net) for
the three months ended March 31, 1997 and 1996, respectively, included all
compensation to non-owner physicians, as well as certain benefits, educational
and travel costs paid to non-owner and owner physicians.  The increase was due
to additional non-owner physician salaries paid in relation to hospital
management contracts.  Physician owners' compensation was recorded as a
distribution of Advanced's equity.  Such amounts were determined based on cash
earnings available for distribution, including cash to be realized from the
collection of accounts receivable.

     Practice salaries, wages and benefits increased by $1.4 million or 54% to
$3.9 million for the three months ended March 31, 1997 from $2.5 million for
the three months ended March 31, 1996.  This change resulted from increases in
the number of employees required to support the additional radiology practices
and new hospital management contracts.  The percentage of practice salaries,
wages and benefits to medical service revenue, net was 25% and 21% for the
three months ended March 31, 1997 and 1996, respectively.





                                      112
<PAGE>   149
     Practice supplies of $0.8 million and $0.6 million for the three months
ended March 31, 1997 and 1996, respectively, remained consistent at 5% of
medical service revenue, net.  Practice rent and lease expense of $0.8 million
and $0.6 million for the three months ended March 31, 1997 and 1996,
respectively, remained consistent at 5% of medical service revenue, net.
Depreciation and amortization expense of $1.0 million and $0.9 million for the
three months ended March 31, 1997 and 1996, respectively, reflects no material
changes in the composition of fixed assets or depreciation methods.  Other
practice expenses of $1.7 million and $1.3 million for the three months ended
March 31, 1997 and 1996, respectively, remained consistent at 11% of medical
service revenue, net.  Interest expense increased by $0.1 million or 152% to
$0.2 million for the three months ended March 31, 1997 from $0.1 million for
the three months ended March 31, 1996 due to an increase in debt attributable
to the addition of a radiology group in April 1996 and teleradiology equipment
purchased in 1996.

  YEAR ENDED DECEMBER 31, 1996 AS COMPARED TO YEAR ENDED DECEMBER 31, 1995

     Medical service revenue, net increased by $14.3 million or 38% to $51.7
million for the year ended December 31, 1996 from $37.4 million for the year
ended December 31, 1995.  This increase was attributable to the addition of a
radiology group in April 1996, new hospital management contracts and an
increase in procedures and/or covered lives at existing facilities.

     Costs of affiliated physician services of $2.3 million (4% of medical
service revenue, net) and $0.8 million (2% of medical service revenue, net) for
the years ended December 31, 1996 and 1995, respectively, included all
compensation to non-owner physicians, as well as certain benefits, educational
and travel costs paid to non-owner and owner physicians.  The increase was due
to additional non-owner physician salaries paid in relation to hospital
management contracts.  In addition, during 1996, the company acquired a
radiology practice whose physicians were paid a salary during a portion of the
year.  Physician owners' compensation was recorded as a distribution of
Advanced's equity.  Such amounts were determined based on cash earnings
available for distribution, including cash to be realized from the collection
of accounts receivable.

     Practice salaries, wages and benefits increased by $2.3 million or 23% to
$12.3 million for the year ended December 31, 1996 from $10.1 million for the
year ended December 31, 1995.  This increase resulted from the increase of
employees related to the addition of a radiology practice and the addition of
employees required to support new hospital management contracts.  The
percentage of practice salaries, wages and benefits to medical service revenue,
net was 24% for the year ended December 31, 1996 and 27% for the year ended
December 31, 1995.

     Practice supplies of $3.2 million and $2.6 million for the years ended
December 31, 1996 and 1995, respectively, were 6% and 7%, respectively, of
medical service revenue, net.  Practice rent and lease expense of $2.3 million
and $2.2 million for the years ended December 31, 1996 and 1995, respectively,
were 4% and 6%, respectively, of medical service revenue, net.  Depreciation
and amortization expense of $3.4 million and $3.0 million for the years ended
December 31, 1996 and 1995, respectively, reflects no material changes in the
composition of fixed assets or depreciation methods.  Other practice expenses
of $6.3 million and $4.2 million for the years ended December 31, 1996 and
1995, respectively, were 12% and 11%, respectively, of medical service revenue,
net.  Interest expense decreased by $0.3 million or 25% to $0.8 million for the
year ended December 31, 1996 from $1.0 million for the year ended December 31,
1995 due to a decrease in the average cost of funds to Advanced.

  YEAR ENDED DECEMBER 31, 1995 AS COMPARED TO YEAR ENDED DECEMBER 31, 1994

     Advanced was formed through the merger of five existing radiology
practices and began operations on January 1, 1995.  Each practice contributed
certain assets (primarily fixed assets and investments in joint ventures) and
the debt related to those assets in exchange for ownership interests in
Advanced.  The initial formation was accounted for using purchase accounting
under the provisions of APB No. 16.  Based on the asset sizes of the individual
contributed radiology practices, one practice was identified as the acquirer,
and, accordingly, all balances prior to January 1, 1995, represent the
activities of this practice on a stand-alone basis.  All significant changes in
operations for the year ended December 31, 1995 as compared to the year ended
December 31, 1994, other than as discussed below are the result of this
organizational change.

     Costs of affiliated physician services decreased $7.9 million or 91% to
$0.8 million for the year ended December 31, 1995 from $8.8 million for the
year ended December 31, 1994.  As a result of the merger discussed above,
Advanced changed its methodology of paying physician owners.  In 1994,
compensation and benefits paid or payable to owner and non-owner physicians was
recorded as an expense.  In 1995, physician owners' compensation was recorded
as a distribution of Advanced's equity.

                                 THE IDE GROUP

                       OPERATION, MANAGEMENT AND BUSINESS

GENERAL

     The Ide Group is a professional medical radiology group formed in 1980 and
organized as a New York professional corporation.  The Ide Group provides two
types of services: (1) professional diagnostic and interpretive services
("Professional Services") and (2) imaging services including x-ray, fluoroscopy,
computed tomography, magnetic resonance imaging, mammography and ultrasound
("Imaging Services"), both of which are reimbursed on a prepaid or
fee-for-service basis.  The Ide Group operates in the greater Rochester, New
York area (the "Ide Service Area").  The Ide Group contracts directly with
hospitals, health plans and [others] to provide Professional Services and
Imaging Services to enrollees and patients.  The Ide Group operates eight
Professional Service and Imaging Service locations and five hospital-based
locations within the Ide Service Area.

     The Ide Group has grown through a combination of acquisitions of medical
practices that complement its services and recruitment of individual associate
physicians in needed practice areas.

STRATEGY

     The Ide Group's strategy is to continue penetration of its existing
markets, expand into other markets, create strategic alliances with hospitals
and other Imaging Service providers, increase the operational efficiency of,
and reduce costs associated with, The Ide Group operations.

     The future growth of The Ide Group in its existing markets is dependent in
part on the continued increase of health plan enrollees and patients using The
Ide Group for Professional Services.  This growth may come, with respect to
Professional Services, from the development or acquisition of additional
facilities and the development of affiliations with medical groups serving
enrollees or patients in existing markets, increased enrollment in health plans
currently contracting with The Ide Group and its medical affiliates, and
contracts with new health plans or hospitals.  It actively recruits new
providers and seeks to enter into new hospital-based or managed care contracts
in order to enlarge the potential patient base in its service areas.

     The Ide Group's principal strategy for expanding into new markets is
through acquisitions (through purchase, merger, or otherwise) of medical
groups.  The Ide Group generally seeks providers that have established
reputations for providing quality medical care.

GOVERNMENT REGULATION

     The Ide Group is subject to federal and state laws regulating the
relationships among providers of health care services, physicians and other
clinicians.  These laws include the fraud and abuse provisions of the Medicare
and Medicaid statutes, which prohibit the solicitation, payment, receipt or
offering of any direct or indirect remuneration for the referral of Medicare or
Medicaid patients or for the recommending, leasing, arranging, ordering or
purchasing of Medicare or Medicaid covered services.  Other laws impose
significant penalties for false or improper billings for physician services and
impose restrictions on physician referrals for designated health services
reimbursable under the Medicare or Medicaid programs to entities with which
they have financial relationships. While The Ide Group believes it is in
material compliance with applicable laws, there is no assurance that its
present or past operations will not be subjected to scrutiny or legal
challenges.

SERVICES PROVIDED

     The Ide Group operates a total of 13 facilities that are staffed by The
Ide Group Professional Service providers and Imaging Service providers.  As of
April 30, 1997, The Ide Group employed 30 Professional Service providers.

     The Ide Group provides its Professional Service and Imaging Service under
capitated contracts and fee-for-service or hospital contracts.  Under capitated
contracts, The Ide Group provides or arranges for all physician services and
The Ide Group receives a fixed monthly capitation payment from health plans for
each member who utilizes The Ide Group physician.





                                      115
<PAGE>   152
     The Ide Group has significant contracts with the following health plans:
Blue Cross/Blue Shield of Greater Rochester, Blue Choice, Preferred Care,
Medicare and Medicaid.

COMPETITION

     The health care industry is highly competitive.  The industry is also
subject to continuing changes in the services that are provided and how
providers are selected and paid.

EMPLOYEES

  PROFESSIONAL SERVICE PROVIDER EMPLOYEES

     The Ide Group physicians enter into employment contracts.  These contracts
offer a specified guaranteed salary and an incentive bonus.  Physicians are
also eligible to receive benefits such as health, dental and life insurance,
paid time off and an allowance for continuing medical education and other
professional expenses.  The Ide Group, as of April 30, 1997, employs 30
physicians.

  NON-PROVIDER EMPLOYEES

     As of April 30, 1997, The Ide Group had approximately 127 non-physician
employees.  None of The Ide Group's employees are represented by a labor union.
Management of The Ide Group believes its employee relations are good.

INSURANCE

     The Ide Group maintains insurance coverage for various perils and from
various carriers.  In addition to property and casualty, worker's compensation,
directors and officers liability and other coverage The Ide Group believes to
be customary and reasonable for a business of its kind, The Ide Group maintains
general and professional liabilities insurance policies (the "Liability
Policies") with Royal Insurance, Massachusetts Mutual and Travelers.  Each
professional of The Ide Group, at each location, is covered under the Liability
Policies.

PROPERTIES AND FACILITIES

     The Ide Group leases approximately eight facilities.  The square footage
of these real property leases ranges from 265 square feet to 7,737 square feet.
Real property leases are used for The Ide Group's corporate operations,
Professional Services and Imaging Services.

INFORMATION SYSTEMS

     The Ide Group believes that the effective analysis of medical and
financial data is essential in today's managed care environment.  Accordingly,
The Ide Group is committed to the development of a fully-integrated management
information system ("MIS") for practice management.  The Ide Group's MIS
capabilities include medical charting and tracking analysis of practice
management information and financial data.  Practice management functions of
the current MIS include registration, centralized scheduling and appointments,
electronic claims submission and remittance.  Managed care functions include
referrals, eligibility, determination, claim management and payment functions.

LEGAL PROCEEDINGS

     The Ide Group is engaged in the defense of lawsuits arising in the
ordinary course and conduct of its business.  The Ide Group believes that such
actions will not have a material adverse effect on The Ide Group.

                                  OPERATIONS

     The following discussion relates to the historical operations of Ide and
should be read in conjunction with the audited financial statements of Ide and
the notes thereto appearing elsewhere in this Prospectus/Joint Proxy Statement.
For purposes of the following discussion, medical service revenue, net
represents the estimated realizable amount to be received from patients, third
party payors and others for the provision of medical services.

1996

     Revenues remained consistent at $19.7 million for each of the nine months
ended March 31, 1997 and 1996.

     Costs of affiliated physician services of $9.4 million and $7.8 million
for the nine months ended March 31, 1997 and 1996, respectively, included
compensation and benefits paid or payable to owner and non-owner physicians
during the period. The physician owners determined such payments based on cash
earnings available for distribution.  Such amounts were 48% and 40%,

increase in the number of procedures performed which resulted from the
establishment of a new facility.

     Costs of affiliated physician services of $11.5 million and $10.9 million

service revenue, net.  Depreciation and amortization expense of $0.8 million
for each of the years ended June 30, 1996 and 1995 reflects no material changes
in the composition of fixed assets or depreciation methods.  Other practice
expenses of $3.4 million and $3.2 million for the years ended June 30, 1996 and
1995, respectively, remained consistent at 13% of medical service revenue, net.

     Revenues increased $1.2 million or 5% to $25.5 million for the year ended

                              M&S X-RAY PRACTICES

                       OPERATION, MANAGEMENT AND BUSINESS

GENERAL

     M&S X-Ray Practices consist of a professional medical radiology group
formed in 1990 and organized as a Texas professional association and six other
related entities.  M&S X-Ray Practices provide two types of services: (1)
professional diagnostic and interpretive services ("Professional Services") and
(2) imaging services including x-ray, fluoroscopy, computed tomography, magnetic
resonance imaging, mammography and ultrasound ("M&S Imaging Services"), both of
which are reimbursed on a prepaid or fee-for-service basis.  M&S X-Ray Practices
operate in the San Antonio, Texas Metropolitan area (the "Service Area").  M&S
X-Ray Practices' contracts directly with hospitals and health plans to provide
Professional Services and Imaging Services to enrollees and patients.  M&S X-Ray
Practices operate three Professional Service locations, four Imaging Service
locations and five hospital-based locations within the M&S Service Area.

     M&S X-Ray Practices have grown through a combination of acquisitions of
medical practices that complement its services and recruitment of individual
associate physicians in needed practice areas.

     M&S X-Ray Practices own 3 limited partnership units in Stone Oak limited
partnership and a 49% interest in Southeast Baptist Imaging Center, Northeast
Baptist Imaging Center and Baptist Imaging Center.  In addition, one of the
related entities of M&S X-Ray Practices holds a 60% interest in Lexington MR
Ltd.  Each of these joint ventures owns and operates diagnostic imaging centers.

STRATEGY

     M&S X-Ray Practices' strategy is to continue penetration of its existing
markets, expand into other markets, create strategic alliances with hospitals
and other Imaging Service providers, increase the operational efficiency of,
and reduce costs associated with, the M&S X-Ray Practices operations.

     The future growth of M&S X-Ray Practices in its existing markets is
dependent in part on the continued increase of health plan enrollees and
patients using M&S X-Ray Practices for Professional Services.  This growth may
come, with respect to Professional Services, from the development or
acquisition of additional facilities and the development of affiliations with
medical groups serving enrollees or patients in existing markets, increased
enrollment in health plans currently contracting with M&S X-Ray Practices and
their medical affiliates, and contracts with new health plans or hospitals.
M&S X-Ray Practices actively recruit new providers and seek to enter into new
hospital-based or managed care contracts in order to enlarge the potential
patient base in its service areas.

     M&S X-Ray Practices' principal strategy for expanding into new markets is
through acquisitions (through purchase, merger, or otherwise) of medical
groups.  M&S X-Ray Practices generally seek providers that have established
reputations for providing quality medical care.

GOVERNMENT REGULATION

     M&S X-Ray Practices are subject to federal and state laws regulating the
relationships among providers of health care services, physicians and other
clinicians.  These laws include the fraud and abuse provisions of the Medicare
and Medicaid statutes, which prohibit the solicitation, payment, receipt or
offering of any direct or indirect remuneration for the referral of Medicare or
Medicaid patients or for the recommending, leasing, arranging, ordering or
purchasing of Medicare or Medicaid covered services.  Other laws impose
significant penalties for false or improper billings for physician services and
impose restrictions on physician referrals for designated health services
reimbursable under the Medicare or Medicaid programs to entities with which they
have financial relationships. While M&S X-Ray Practices believe that they are in
material compliance with applicable laws, there is no assurance that their
present or past operations will not be subjected to scrutiny or legal
challenges.

SERVICES PROVIDED

     M&S X-Ray Practices operate a total of 12 facilities that are staffed by
M&S X-Ray Practices Professional Service providers and M&S X-Ray Practices
Imaging Service providers.  As of April 30, 1997, M&S X-Ray Practices employed
20 Professional Service providers.





                                      120
<PAGE>   157
     M&S X-Ray Practices provide their Professional Services and Imaging
Services under capitated contracts and fee-for-service or hospital contracts.
Under capitated contracts, M&S X-Ray Practices provide or arrange for all
physician services and M&S X-Ray Practices receive a fixed monthly capitation
payment from health plans for each member who utilize an M&S X-Ray Practices
physician.

     From January 1, 1997 through April 30, 1997, over 120,000 patients were
serviced by M&S X-Ray Practices.  M&S X-Ray Practices have significant
contracts with the Baptist Health System.

COMPETITION

     The health care industry is highly competitive.  The industry is also
subject to continuing changes in the services that are provided and how
providers are selected and paid.

EMPLOYEES

  PROFESSIONAL SERVICE PROVIDER EMPLOYEES

     M&S X-Ray Practices' physicians enter into employment contracts.  These
contracts offer a specified guaranteed salary and an incentive bonus.

life insurance, paid time off and an allowance for continuing medical education
and other professional expenses.  M&S X-Ray Practices, as of April 30, 1997,
employs 20 physicians.

non-physician employees.  None of M&S X-Ray Practices' employees are
represented by a labor union.  Management of M&S X-Ray Practices believes its
employee relations are good.

INSURANCE

     M&S X-Ray Practices maintain insurance coverage for various perils and
from various carriers.  In addition to property and casualty, worker's
compensation, directors and officers liability and other coverage M&S X-Ray
Practices believe to be customary and reasonable for a business of its kind,
M&S X-Ray Practices maintain general and professional liabilities insurance
policies (the "Liability Policies") with EMC Mutual Assurance, Potomac
Insurance, Insurance Corp. of America and United National.  Each professional
of M&S X-Ray Practices, at each location, is covered under the Liability
Policies.


PROPERTIES AND FACILITIES

     M&S X-Ray Practices lease approximately six facilities.  The square
footage of such facilities range from 1,750 square feet to 5,662 square feet.
The real property leases of M&S X-Ray Practices are utilized for office space.

INFORMATION SYSTEMS

     M&S X-Ray Practices believe that the effective analysis of medical and
financial data is essential in today's managed care environment.  Accordingly,
M&S X-Ray Practices are committed to the development of a fully-integrated
management information system ("MIS") for practice management.  M&S X-Ray
Practices' MIS capabilities include medical charting and tracking analysis of
practice management information and financial data.  Practice management
functions of the current MIS include registration, electronic claims submission
and remittance.  Managed care functions include referrals, eligibility,
determination, claim management and payment functions.

LEGAL PROCEEDINGS

     M&S X-Ray Practices are engaged in the defense of lawsuits arising in the
ordinary course and conduct of their businesses.  M&S X-Ray Practices believe
that such actions may have a material adverse effect on M&S X-Ray Practices.

          M&S X-RAY PRACTICES MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion relates to the historical operations of M & S
X-Ray Practices and should be read in conjunction with the audited financial
statements of M & S X-Ray Practices and the notes thereto appearing elsewhere
in this Prospectus/Joint Proxy Statement. For purposes of the following
discussion, medical service revenue, net represents the estimated realizable
amount to be received from patients, third party payors and others for the
provision of medical services.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1997 AS COMPARED TO THREE MONTHS ENDED MARCH 31,
1996

     Medical service revenue, net decreased by $0.3 million or 7% to $3.4
million for the three months ended March 31, 1997 from $3.7 million for the
three months ended March 31, 1996.  The decrease was attributable to a decrease
in the number of procedures performed.

     Costs of affiliated physician services of $1.8 million (53% of medical
service revenue, net) and $1.6 million (44% of medical service revenue, net)
for the three months ended March 31, 1997 and 1996, respectively, included
compensation and benefits paid or payable to owner and non-owner physicians
during the period.  The physician owners determined such payments based on cash
earnings available for distribution.  The increase was due to improved
collections in the first quarter of 1997 as compared to the first quarter of
1996.

     Practice salaries, wages and benefits increased $0.3 million or 118% to
$0.5 million for the three months ended March 31, 1997 from $0.2 million for the
three months ended March 31, 1996.  For the three months ended March 31, 1996,
an outside management company paid all administrative salaries of M&S.  During
1997, these salaries were paid by M&S.

     Practice rent and lease expense remained consistent at 2% of medical
service revenue, net for the three months ended March 31, 1997 and 1996.
Depreciation and amortization expense decreased $0.1 million or 57% to $0.1
million for the three months ended March 31, 1997 from $0.2 million for the
three months ended March 31, 1996 as certain assets became fully depreciated.
M&S had no material changes in the composition of fixed assets or depreciation
methods.  Other practice expenses decreased $0.5 million or 64% to $0.3 million
for the three months ended March 31,





                                      122
<PAGE>   159
1997 from $0.8 million for the three months ended March 31, 1996 due to a
reduction in fees paid to an outside management company.

  YEAR ENDED DECEMBER 31, 1996 AS COMPARED TO YEAR ENDED DECEMBER 31, 1995

     Medical service revenue, net increased by $0.1 million or 0.4% to $14.8
million for the year ended December 31, 1996 from $14.7 million for the year
ended December 31, 1995 reflecting a consistent level of operations.

     Investment income from joint ventures of $0.6 million and $0.2 million for
the years ended December 31, 1996 and 1995, respectively, represented M&S' 49%
interest in the earnings of three joint ventures.  The increase was attributable
to increased volume at each of the joint ventures.

     Other revenue increased by $0.1 million or 21% to $0.4 million for the
year ended December 31, 1996 from $0.3 million for the year ended December 31,
1995 due to increased management fees earned from joint ventures.  Management
fees were computed as a percentage of cash collections; therefore, as earnings
of the joint ventures increase, the related management fees also increase.

     Costs of affiliated physician services of $8.7 million (59% of medical
service revenue, net) and $8.9 million (60% of medical service revenue, net)
for the years ended December 31, 1996 and 1995, respectively, included
compensation and benefits paid or payable to owner and non-owner physicians
during the period.  The physician owners determined such payments based on cash
earnings available for distribution.

     Practice salaries, wages and benefits increased $0.1 million or 9% to $1.3
million for the year ended December 31, 1996 from $1.2 million for the year
ended December 31, 1995.  For seven months of 1995, an outside management
company paid all administrative salaries of M&S.  During 1996, five months of
administrative salaries were paid by the outside management company.

     Practice supplies increased $0.1 million or 18% to $0.6 million for the
year ended December 31, 1996 from $0.5 million for the year ended December 31,
1995 due to increased costs of certain supplies.  Practice rent and lease
expense remained consistent at 2% of medical service revenue, net for the years
ended December 31, 1996 and 1995.  Depreciation and amortization expense
decreased $0.3 million or 30% to $0.7 million for the year ended December 31,
1996 from $1.0 million for the year ended December 31, 1995 as certain assets
became fully depreciated.  The company had no material changes in the
composition of fixed assets or depreciation methods.  Other practice expenses
decreased $0.4 million or 19% to $1.5 million for the year ended December 31,
1996 from $1.9 million for the year ended December 31, 1995 due to a reduction
in fees paid to an outside management company.

                          PACIFIC IMAGING CONSULTANTS

                       OPERATION, MANAGEMENT AND BUSINESS

GENERAL

     Pacific Imaging Consultants is comprised of a professional medical
radiology group formed in 1978 and organized as a California professional
medical corporation and Total Medical Imaging, Inc., a California corporation.
Pacific Imaging Consultants provides two types of services: (1) professional
diagnostic and interpretive services ("Professional Services") and (2) imaging
services including x-ray, fluoroscopy, computed tomography, magnetic resonance
imaging, mammography, nuclear medicine and ultrasound ("Imaging Services"), both
of which are reimbursed on a prepaid and fee-for-service basis.  Pacific Imaging
Consultants operates in the greater Oakland Metropolitan area, San Francisco Bay
area and in the Hi-Desert area of Southern California (the "Pacific Service
Area").  Pacific Imaging Consultants contracts directly with hospitals and
health plans to provide Professional Services and Imaging Services to enrollees
and patients.  Through contracts with various health plans and hospitals, as of
April 30, 1997, Pacific Imaging Consultants physicians were responsible for the
Professional Services and Imaging Services to approximately 360,000 health plan
enrollees or patients.  Pacific Imaging Consultants operates five Professional
Service locations and seven Imaging Service locations.

     Pacific Imaging Consultants has grown through a combination of
acquisitions of medical practices that complement its services and recruitment
of individual associate physicians in needed practice areas.

STRATEGY

     Pacific Imaging Consultants' strategy is to continue penetration of its
existing markets, expand into other markets, create strategic alliances with
hospitals and other Imaging Service providers, increase the operational
efficiency of, and reduce costs associated with, the Pacific Imaging
Consultants operations.

     The future growth of Pacific Imaging Consultants in its existing markets is
dependent in part on the continued increase of health plan enrollees and
patients using Pacific Imaging Consultants for Professional Services.  This
growth may come, with respect to Professional Services, from the development or
acquisition of additional facilities and the development of affiliations with
medical groups serving enrollees or patients in existing markets, increased
enrollment in health plans currently contracting with Pacific Imaging
Consultants and its medical affiliates, and contracts with new health plans or
hospitals.  It actively recruits new providers and seeks to enter into new
hospital-based or managed care contracts in order to enlarge the potential
patient base in the Pacific Service Area.

     Pacific Imaging Consultants' principal strategy for expanding into new
markets is through acquisitions (through purchase, merger, or otherwise) of
medical groups.  Pacific Imaging Consultants generally seeks providers that
have established reputations for providing quality medical care.

GOVERNMENT REGULATION

     Pacific Imaging Consultants is subject to federal and state laws
regulating the relationships among providers of health care services,
physicians and other clinicians.  These laws include the fraud and abuse
provisions of the Medicare and Medicaid statutes, which prohibit the
solicitation, payment, receipt or offering of any direct or indirect
remuneration for the referral of Medicare or Medicaid patients or for the
recommending, leasing, arranging, ordering or purchasing of Medicare or
Medicaid covered services.  Other laws impose significant penalties for false
or improper billings for physician services and impose restrictions on
physician referrals for designated health services reimbursable under the
Medicare or Medicaid programs to entities with which they have financial
relationships. While Pacific Imaging Consultants believes it is in material
compliance with applicable laws, there is no assurance that its present or past
operations will not be subjected to scrutiny or legal challenges.

SERVICES PROVIDED

     Pacific Imaging Consultants operates a total of 12 facilities that are
staffed by Pacific Imaging Consultants Professional Service providers and
Pacific Imaging Consultants Imaging Service providers.  As of April 30, 1997,
Pacific Imaging Consultants employed 24 Professional Service providers and 28
Imaging Service providers.  Pacific Imaging Consultants provides the following
specialty radiology services:  diagnostic and interpretive, x-ray, fluoroscopy,
computed tomography, mammography, CT, magnetic resonance imaging, nuclear
medicine, ultrasound and interventional.

<PAGE>   167

Service and Imaging Service under capitated contracts and 80% under
fee-for-service or hospital contracts.  Under capitated contracts, Pacific
Imaging Consultants provides or arranges for all physician services and Pacific
Imaging Consultants receives a fixed monthly capitation payment from health
plans for each member who utilize a Pacific Imaging Consultants physician.

      PACIFIC IMAGING CONSULTANTS MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion relates to the historical operations of Pacific
Imaging Consultants and should be read in conjunction with the audited financial
statements of Pacific Imaging Consultants and the notes thereto appearing
elsewhere in this Prospectus/Joint Proxy Statement. For purposes of the
following discussion, medical service revenue, net represents the estimated
realizable amount to be received from patients, third party payors and others
for the provision of medical services.

RESULTS OF OPERATIONS

  THREE MONTHS ENDED MARCH 31, 1997 AS COMPARED TO THREE MONTHS ENDED 
MARCH 31, 1996

     Medical service revenue, net increased $0.8 million or 30% to $3.6 million
for the three months ended March 31, 1997 from $2.8 million for the three
months ended March 31, 1996.  This increase is largely attributable to the
addition of a new hospital contract which resulted in an increase in the number
of procedures performed.

     Costs of affiliated physician services of $2.1 million (59% of medical
service revenue, net) and $1.4 million (49% of medical service revenue, net)
for the three months ended March 31, 1997 and 1996, respectively, included
physician compensation and benefits paid or payable to owner and non-owner
physicians during the period.  The physician owners determined such payments
based on earnings available for distribution.  This increase is primarily due
to the hiring of three new physicians and two other employees subsequent to
March 31, 1996.

     Practice salaries, wages and benefits of $0.5 million and $0.4 million for
the three months ended March 31, 1997 and 1996, respectively, were 13% and 14%,
respectively, of medical service revenue, net.  Practice supplies of 
$0.1 million for each of the three months ended March 31, 1997 and 1996 were 3%
and 4%, respectively, of medical service revenue, net.  Depreciation and
amortization expense of $0.2 million for each of the three months ended March
31, 1997 and 1996 reflects no material changes in the composition of fixed
assets or depreciation methods.  Other practice expenses of $0.5 million and
$0.4 million for the three months ended March 31, 1997 and 1996, respectively,
remained consistent at 13% of medical service revenue, net.  Interest expense of
$0.1 million for each of the three months ended March 31, 1997 and 1996, was 2%
and 4%, respectively, of medical service revenue, net.

<PAGE>   170
  YEAR ENDED DECEMBER 31, 1996 AS COMPARED TO YEAR ENDED DECEMBER 31, 1995

     Medical service revenue, net increased $1.9 million or 17% to $13.1 million
for the year ended December 31, 1996 from $11.2 million for the year ended
December 31, 1995 due primarily to increased revenue under capitated contracts.
In September 1995, Pacific signed a significant capitation contract.  Revenues
under this contract were $1.4 million greater for the year ended December 31,
1996 as compared to the year ended December 31, 1995.  The remaining increase in
revenue was the result of an increased number of procedures performed and
covered lives.

     Costs of affiliated physician services of $7.2 million (55% of medical
service revenue, net) and $5.9 million (52% of medical service revenue, net)
for the years ended December 31, 1996 and 1995, respectively, included
physician compensation and benefits paid or payable to owner and non-owner
physicians during the period.  The physician owners determined such payments
based on earnings available for distribution.

     Practice salaries, wages and benefits were $1.8 million and $1.6 million
for the years ended December 31, 1996 and 1995, respectively, representing 14%
of medical service revenue, net for each year.  Practice supplies of 
$0.6 million and $0.5 million for the years ended December 31, 1996 and 1995,
respectively, remained consistent at 4% of medical service revenue, net.
Practice rent and lease expense of $0.4 million for each of the years ended
December 31, 1996 and 1995 remained consistent at 3% of medical service revenue,
net.  Depreciation and amortization expense of $1.0 million for each of the
years ended December 31, 1996 and 1995 reflects no material changes in the
composition of fixed assets or depreciation methods.  Other practice expenses of
$1.9 million and $1.7 million for the years ended December 31, 1996 and 1995,
respectively, remained consistent at 15% of medical service revenue, net.
Interest expense decreased $0.2 million or 34% to $0.3 million for the year
ended December 31, 1996 from $0.5 million for the year ended December 31, 1995
due to a decrease in the average debt outstanding, as well as a reduction in the
average interest rates applied.  These reductions were achieved through a debt
refinancing which occurred in August 1996.

                         RADIOLOGY AND NUCLEAR MEDICINE

                       OPERATION, MANAGEMENT AND BUSINESS

GENERAL

     RNM is a professional association.  RNM was formed in 1959 as "Radiology
and Nuclear Medicine, an association," the entity as it exists today is the
result of a 1967 merger of the original entity into a Kansas professional
association named "Radiology and Nuclear Medicine, a Professional Association."
RNM provides two types of services: (1) professional diagnostic and
interpretive services and radiation oncology services ("Professional Services")
and (2) imaging services including x-ray, fluoroscopy, computed tomography,
magnetic resonance imaging, mammography and ultrasound ("Imaging Services"),
both of which are reimbursed on a prepaid or fee-for-service basis.  RNM
operates in the greater Topeka, Kansas area (the "RNM Service Area").  RNM
contracts directly with hospitals and health plans to provide Professional
Services and Imaging Services to enrollees and patients.  RNM operates two
Imaging Service locations and provides Professional Services at those locations
and at 11 hospital-based locations within the RNM Service Area.

     RNM has grown through expansion of its service area and extending services
to additional outreach locations within the RNM Service Area.

     RNM owns a 22% interest in Magnetic Resonance Imaging Center of Kansas, a
Kansas limited partnership.

STRATEGY

     RNM's strategy is to continue penetration of its existing markets, expand
into other markets, create strategic alliances with hospitals and other Imaging
Service providers, increase the operational efficiency of, and reduce costs
associated with, the RNM operations.

     The future growth of RNM in its existing markets is dependent in part on
the continued increase of health plan enrollees and patients using RNM
physicians for Professional Services.  This growth may come, with respect to
Professional Services, from the development or acquisition of additional
facilities, and the development of associations with medical groups serving
enrollees or patients in existing markets, increased enrollment in health plans
currently contracting with RNM or parties with which RNM is associated and
contracts with new health plans or hospitals.  It actively recruits new
providers and seeks to enter into new hospital-based or managed care contracts
in order to enlarge the potential patient base in its service areas.

     RNM's principal strategy for expanding into new markets is through
acquisitions (through purchase, merger, or otherwise) of medical groups.  RNM
generally seeks providers that have established reputations for providing
quality medical care.

GOVERNMENT REGULATION

     RNM is subject to federal and state laws regulating the relationships
among providers of health care services, physicians and other clinicians.
These laws include the fraud and abuse provisions of the Medicare and Medicaid
statutes, which prohibit the solicitation, payment, receipt or offering of any
direct or indirect remuneration for the referral of Medicare or Medicaid
patients or for the recommending, leasing, arranging, ordering or purchasing of
Medicare or Medicaid covered services.  Other laws impose significant penalties
for false or improper billings for physician services and impose restrictions
on physician referrals for designated health services reimbursable under the
Medicare or Medicaid programs to entities with which they have financial
relationships. While RNM believes it is in material compliance with applicable
laws, there is no assurance that its present or past operations will not be
subjected to scrutiny or legal challenges.

SERVICES PROVIDED

     RNM provides physician staffing to a total of 14 facilities, including its
two wholly-owned ICs.  As of April 30, 1997, RNM employed 19 diagnostic
radiologists.  RNM also provides radiation oncology services and, as of April
30, 1997, employed five professional service providers (radiation oncologists).
RNM provides all of its Professional Service and Imaging Service under
fee-for-service or hospital contracts.

     At April 30, 1997, approximately 140,000 patients were serviced by RNM.
RNM is under contract with the following significant hospitals or health plans:
MediCare, Kansas Medicaid, Heartland/Horizons Health Plan, Blue Shield of
Kansas, Premier Blue, Prudential, CHAMPUS, Century Health Solutions,

<PAGE>   174
     RNM undertakes concurrent review of cases which are reevaluated for
radiologic interpretation, adequate film technique and positioning, and typing
accuracy.  A follow-up file of cases with significant pathology, including
suspected malignancy, is maintained to determine outcome.

MARKETING AND DEVELOPMENT

     Radiology and Nuclear Medicine's marketing and development plans include
participation in health fairs and business fairs, brochure advertising,
sponsorship of local activities and events and direct marketing to referring
physicians and their staffs by providing educational materials of use and
interest to them in their practices.

COMPETITION

     The health care industry is highly competitive.  The industry is also
subject to continuing changes in the services that are provided and how
providers are selected and paid.

     RNM is the leading provider of diagnostic imaging and radiation therapy
services within its service area.  There is one other professional radiology
group operating in each of the Kansas cities in Atchison, Manhattan, Lawrence
and Emporia.  In Topeka and other portions of the service area, RNM's
competition is limited to non-specialists.

EMPLOYEES

  PROFESSIONAL SERVICE PROVIDER EMPLOYEES

     RNM physicians enter into employment contracts.  These contracts offer a
specified guaranteed salary and an incentive bonus.  Physicians are also
eligible to receive benefits such as health, dental and life insurance, paid
time off and an allowance for continuing medical education and other
professional expenses.  RNM, as of April 30, 1997, employed 24 full-time
physicians.

  NON-PROVIDER EMPLOYEES

     As of April 30, 1997, RNM had approximately 45 non-physician employees (40
full time and five part-time).  None of RNM's employees are represented by a
labor union.  Management of RNM believes its employee relations are good.

INSURANCE

     RNM maintains insurance coverage for various perils and from various
carriers.  In addition to property and casualty, worker's compensation and
other coverage, RNM believes to be customary and reasonable for a business of
its kind, RNM maintains general and professional liability insurance policies
with Kansas Medical Mutual and Cincinnati Insurance.  Each professional of RNM
at each location is covered under these general and professional liability
insurance policies.

PROPERTIES AND FACILITIES

     RNM leases two facilities for office space.  The square footage of such
real property leases are 3,572 square feet and 13,865 square feet,
respectively.

INFORMATION SYSTEMS

     RNM believes that the effective analysis of medical and financial data is
essential in today's managed care environment.  Accordingly, RNM is committed
to the development of a fully-integrated management information system ("MIS")
for practice management.  RNM's MIS capabilities include tracking analysis of
practice management information and financial data.  Practice management
functions of the current MIS include patient registration, referral tracking,
physician scheduling and productivity, and electronic claims submission and
remittance.

LEGAL PROCEEDINGS

     RNM is engaged in the defense of lawsuits arising in the ordinary course
and conduct of its business.  RNM believes that such actions will not have a
material adverse effect on RNM.

      RNM MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

     The following discussion relates to the historical operations of RNM and
should be read in conjunction with the audited financial statements of RNM and
the notes thereto appearing elsewhere in this Prospectus/Joint Proxy Statement.
For purposes of the following discussion, medical service revenue, net
represents the estimated realizable amount to be received from patients, third
party payors and others for the provision of medical services.

  THREE MONTHS ENDED MARCH 31, 1997 AS COMPARED TO THREE MONTHS ENDED MARCH 31,
1996

     Medical service revenue, net increased $0.5 million or 17% to $3.6 million
for the three months ended March 31, 1997 from $3.1 million for the three
months ended March 31, 1996.  This increase was attributable to the addition,
in July 1996, of a new hospital at which the company provided services.

     Costs of affiliated physician services of $2.1 million (58% of medical
service revenue, net) and $2.0 million (66% of medical service revenue, net)
for the three months ended March 31, 1997 and 1996, respectively, included
compensation and benefits paid or payable to owner and non-owner physicians
during the period.  The physician owners determined such payments based on cash
earnings available for distribution.

     Practice salaries, wages and benefits remained consistent at $0.4 million
for each of the three months ended March 31, 1997 and 1996.  Such amounts were
10% and 11%, respectively, of medical service revenue, net.  Other practice
expenses of $0.2 million for each of the three months ended March 31, 1997 and
1996 remained consistent at 5% of medical service revenue, net.

  YEAR ENDED DECEMBER 31, 1996 AS COMPARED TO YEAR ENDED DECEMBER 31, 1995

     Medical service revenue, net decreased $0.3 million or 2% to $13.4 million
for the year ended December 31, 1996 from $13.7 million for the year ended
December 31, 1995.  Although the company had a slight increase in volume of
services rendered, reimbursement rates from certain payor groups declined.





                                      139
<PAGE>   176
     Costs of affiliated physician services of $10.3 million (76% of medical
service revenue, net) and  10.7 million (78% of medical service revenue, net)
for the years ended December 31, 1996 and 1995, respectively, included
compensation and benefits paid or payable to owner and non-owner physicians
during the period.  The physician owners determined such payments based on cash
earnings available for distribution.

     Practice salaries, wages and benefits of $1.7 million and $1.8 million for
the years ended December 31, 1996 and 1995, respectively, remained consistent
as 13% of medical service revenue, net.  Practice supplies of $0.3 million and
$0.4 million for the years ended December 31, 1996 and 1995, respectively, were
2% and 3% of medical service revenue, net, respectively.  Depreciation and
amortization expense of $0.2 million for each of the years ended December 31,
1996 and 1995 reflects no material changes in the composition of fixed assets
or depreciation methods.  Other practice expenses of $0.8 million for each of
the years ended December 31, 1996 and 1995 remained consistent at 6% of medical
service revenue, net.

                          ROCKLAND RADIOLOGICAL GROUP

                       OPERATION, MANAGEMENT AND BUSINESS

GENERAL

     Rockland Radiological Group is comprised of seven professional medical
radiology groups, each of which is organized as a New York professional
corporation.  Rockland Radiological Group provides two types of services: (1)
professional diagnostic and interpretive services ("Professional Services") and
(2) imaging services including x-ray, fluoroscopy, computed tomography, magnetic
resonance imaging, mammography and ultrasound ("Imaging Services"), both of
which are reimbursed on a prepaid or fee-for-service basis.  Rockland
Radiological Group operates in the Dutchess, Orange, Rockland, Ulster and
Westchester County areas of the State of New York and the Bergen County area of
the State of New Jersey (the "Rockland Service Area").  Rockland Radiological
Group contracts directly with hospitals and health plans to provide Professional
Services and Imaging Services to enrollees and patients.  Rockland Radiological
Group operates five Professional Service and Imaging Service locations and two
hospital-based locations within the Rockland Service Area.

     Rockland Radiological Group has grown through a combination of
acquisitions of medical practices that complement its services and recruitment
of individual associate physicians in needed practice areas.  On March 11,
1997, Wallkill Radiology Associates, P.C. and Mid-Hudson Radiology Associates,
P.C. agreed to contribute all of their assets to Rockland Radiological Group.
In April 1997, Rockland Radiological Group entered into an agreement to
purchase certain assets of Kingston Diagnostic Radiology, P.C.

STRATEGY

     Rockland Radiological Group's strategy is to continue penetration of its
existing markets, expand into other markets, create strategic alliances with
hospitals and other Imaging Service providers, increase the operational
efficiency of, and reduce costs associated with, the Rockland Radiological
Group operations.

     The future growth of Rockland Radiological Group in its existing markets
is dependent in part on the continued increase of health plan enrollees and
patients using Rockland Radiological Group for Professional Services.  This
growth may come, with respect to Professional Services, from the development or
acquisition of additional facilities; and the development of affiliations with
medical groups serving enrollees or patients in existing markets, increased
enrollment in health plans currently contracting with Rockland Radiological
Group and its medical affiliates, and contracts with new health plans or
hospitals.  It actively recruits new providers and seeks to enter into new
hospital- based or managed care contracts in order to enlarge the potential
patient base in its Service Area.

     Rockland Radiological Group's principal strategy for expanding into new
markets is through acquisitions (through purchase, merger, or otherwise) of
medical groups.  Rockland Radiological Group generally seeks providers that
have established reputations for providing quality medical care.

GOVERNMENT REGULATION

     Rockland Radiological Group is subject to federal and state laws
regulating the relationships among providers of health care services,
physicians and other clinicians.  These laws include the fraud and abuse
provisions of the Medicare and Medicaid statutes, which prohibit the
solicitation, payment, receipt or offering of any direct or indirect
remuneration for the referral of Medicare or Medicaid patients or for the
recommending, leasing, arranging, ordering or purchasing of Medicare or
Medicaid covered services.  Other laws impose significant penalties for false
or improper billings for physician services and impose restrictions on
physician referrals for designated health services reimbursable under the
Medicare or Medicaid programs to entities with which they have financial
relationships. While Rockland Radiological Group believes it is in material
compliance with applicable laws, there is no assurance that its present or past
operations will not be subjected to scrutiny or legal challenges.

SERVICES PROVIDED

     Rockland Radiological Group operates a total of seven facilities that are
staffed by Rockland Radiological Group Professional Service providers and
Rockland Radiological Group Imaging Service providers.  As of April 30, 1997,
Rockland Radiological Group employed 14 Professional Service providers.





                                      142
<PAGE>   179
     Rockland Radiological Group provides approximately 11% of its Professional
Service and Imaging Service under capitated contracts and 8% under
fee-for-service or hospital contracts.  Under capitated contracts, Rockland
Radiological Group provides or arranges for all physician services and Rockland
Radiological Group receives a fixed monthly capitation payment from health
plans for each member who utilizes a Rockland Radiological Group physician.

     At April 30, 1997, over 18,000 patients were serviced by Rockland
Radiological Group under a capitated plan.

     Rockland Radiology Group provides an extensive and ongoing utilization
review process under the direction of a committee of physician members.  The
program includes both prospective and retrospective analysis of utilization.

MARKETING AND DEVELOPMENT

     Rockland Radiology Group employs a staff of full-time and part-time
marketing and development personnel.  This staff works with physicians and
physician groups, health plans and hospitals to familiarize them with the
facilities and services of the Rockland Radiology Group.  The Rockland
Radiology Group actively solicits statewide regional contracts in health plans
and other third party payors.

subject to continuing changes in the services that are provided and how
providers are selected and paid.

      ROCKLAND RADIOLOGICAL GROUP MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion relates to the historical operations of RRG and
should be read in conjunction with audited financial statements of RRG and the
notes thereto appearing elsewhere in this Prospectus/Joint Proxy Statement. For
purposes of the following discussion, medical service revenue, net represents
the estimated realizable amount to be received from patients, third party
payors and others for the provision of medical services.

RESULTS OF OPERATIONS

  SIX MONTHS ENDED MARCH 31, 1997 AS COMPARED TO SIX MONTHS ENDED MARCH 31, 1996

     Medical service revenue, net increased by $1.1 million or 15% to $8.9
million for the six months ended March 31, 1997 from $7.8 million for the six
months ended March 31, 1996.  This increase was attributable to the addition of
new equipment at the company's imaging centers which resulted in an increase in
procedures performed.

     Costs of affiliated physician services of $2.7 million (31% of medical
service revenue, net) and $2.4 million (31% of medical service revenue, net)
for the six months ended March 31, 1997 and 1996, respectively, included
compensation and benefits paid or payable to owner and non-owner physicians
during the period.  The physician owners determined such payments based on cash
earnings available for distribution.

     Practice salaries, wages and benefits of $2.2 million and $1.9 million for
the six months ended March 31, 1997 and 1996, respectively, remained consistent
at 25% of medical service revenue, net.  Practice supplies of $0.6 million and
$0.5 million for the six months ended March 31, 1997 and 1996, respectively,
remained consistent at 7% of medical service revenue, net.  Depreciation and
amortization expense of $0.6 million and $0.7 million for the six months ended
March 31, 1997 and 1996, respectively, reflects no material changes in the
composition of fixed assets or depreciation methods.  Other practice expenses
of $1.5 million and $1.3 million for the six months ended March 31, 1997 and
1996, respectively, were 17% and 18%, respectively, of medical service revenue,
net.

<PAGE>   182
  YEAR ENDED SEPTEMBER 30, 1996 AS COMPARED TO YEAR ENDED SEPTEMBER 30, 1995

     Medical service revenue, net decreased by $0.5 million or 3% to $17.3
million for the year ended September 30, 1996 from $17.8 million for the year
ended September 30, 1995.  Although the company had a slight increase in volume
of services rendered, reimbursement rates from certain payor groups declined.

     Costs of affiliated physician services of $6.1 million (35% of medical
service revenue, net) and $7.1 million (40% of medical service revenue, net)
for the years ended September 30, 1996 and 1995, respectively, included
compensation and benefits paid or payable to owner and non-owner physicians
during the period.  The physician owners determined such payments based on cash
earnings available for distribution.

     Practice salaries, wages and benefits of $4.3 million and $4.1 million for
the years ended September 30, 1996 and 1995, respectively, were 25% and 23%,
respectively, of medical service revenue, net.  Practice supplies of $1.1
million and $1.2 million for the years ended September 30, 1996 and 1995,
respectively, remained consistent at 7% of medical service revenue, net.
Practice rent and lease expense of $0.1 million and $0.2 million for the years
ended September 30, 1996 and 1995, respectively, remained consistent at 1% of
medical service revenue, net.  Depreciation and amortization expense of $1.4
million and $1.6 million for the years ended September 30, 1996 and 1995,
respectively, reflects no material changes in the composition of fixed assets
or depreciation methods.  Other practice expenses of $3.6 million and $4.0
million for the years ended September 30, 1996 and 1995, respectively, were 21%
and 22%, respectively, of medical service revenue, net.  Interest expense
decreased $0.1 million or 17% to $0.6 million for the year ended September 30,
1996 from $0.7 million for the year ended September 30, 1995 due to reduced
interest costs on capital lease obligations.

  YEAR ENDED SEPTEMBER 30, 1995 AS COMPARED TO YEAR ENDED SEPTEMBER 30, 1994

     Medical service revenue, net increased $2.7 million or 18% to $17.8
million for the year ended September 30, 1995 from $15.1 million for the year
ended September 30, 1994.  This increase was attributable to increased
procedures performed at existing facilities, as well as the addition of
contracts to perform radiological services at new facilities.

     Costs of affiliated physician services of $7.1 million (40% of medical
service revenue, net) and $3.7 million (24% of medical service revenue, net)
for the years ended September 30, 1995 and 1994, respectively, included
compensation and benefits paid or payable to owner and non-owner physicians
during the period.  The physician owners determined such payments based on cash
earnings available for distribution.

million for the year ended September 30, 1995 from $3.9 million for the year
ended September 30, 1994.  These expenses were 23% and 26% of medical service
revenue, net.

     Practice supplies increased $0.6 million or 96% to $1.2 million for the
year ended September 30, 1995 from $0.6 million for the year ended September
30, 1994 due to an increased volume of procedures.  Practice rent and lease
expense of $0.2 million for each of the years ended September 30, 1995 and 1994
remained consistent at 1% of medical service revenue, net.  Depreciation and
amortization expenses of $1.6 million for each of the years ended September 30,
1995 and 1994 reflects no material changes in the composition of fixed assets
or depreciation methods.  Other practice expenses of $4.0 million and $3.6
million for the years ended September 30, 1995 and 1994, respectively, were 22%
and 24%, respectively, of medical service revenue, net.  Interest expense
decreased $0.4 million to $0.7 million for the year ended September 30, 1995
from $1.1 million for the year ended September 30, 1994 due to reduced interest
costs on capital lease obligations.

                             VALLEY RADIOLOGY GROUP

                       OPERATION, MANAGEMENT AND BUSINESS

GENERAL

     Valley Radiology Group is comprised of a professional medical radiology
group formed in 1969 and organized as a California professional corporation and
LXL, LTD., a California partnership.  Valley Radiology Group provides two types
of services: (1) professional diagnostic and interpretive services
("Professional Services") and (2) imaging services including x-ray, fluoroscopy,
computed tomography, magnetic resonance imaging, mammography and ultrasound
("Imaging Services"), both of which are reimbursed on a prepaid and
fee-for-service basis.  Valley Radiology Group operates in the greater San Jose
Metropolitan area and the San Francisco Bay area (the "Valley Service Area").
Valley Radiology Group contracts directly with hospitals, health plans and
others to provide Professional Services and Imaging Services to enrollees and
patients. Valley Radiology Group provides professional services at 20
Professional Service and Imaging Service locations within the Valley Service
Area.

STRATEGY

     Valley Radiology Group's strategy is to continue penetration of its
existing markets, expand into other markets, create strategic alliances with
hospitals and other Imaging Service providers, increase the operational
efficiency of, and reduce costs associated with, the Valley Radiology Group
operations.

     The future growth of Valley Radiology Group in its existing markets is
dependent in part on the continued increase of health plan enrollees and
patients using Valley Radiology Group providers for Professional Services.
This growth may come, with respect to Professional Services, from the
development or acquisition of additional facilities, the development of
affiliations with medical groups serving enrollees or patients in existing
markets, increased enrollment in health plans currently contracting with Valley
Radiology Group and its medical affiliates and contracts with new health plans
or hospitals.  It actively recruits new providers and seeks to enter into new
hospital-based or managed care contracts in order to enlarge the potential
patient base in the Valley Service Area.

GOVERNMENT REGULATION

     Valley Radiology Group is subject to federal and state laws regulating the
relationships among providers of health care services, physicians and other
clinicians.  These laws include the fraud and abuse provisions of the Medicare
and Medicaid statutes, which prohibit the solicitation, payment, receipt or
offering of any direct or indirect remuneration for the referral of Medicare or
Medicaid patients or for the recommending, leasing, arranging, ordering or
purchasing of Medicare or Medicaid covered services.  Other laws impose
significant penalties for false or improper billings for physician services and
impose restrictions on physician referrals for designated health services
reimbursable under the Medicare or Medicaid programs to entities with which
they have financial relationships. While Valley Radiology Group believes it is
in material compliance with applicable laws, there is no assurance that its
present or past operations will not be subjected to scrutiny or legal
challenges.

SERVICES PROVIDED

     Valley Radiology Group operates a total of ten facilities that are staffed
by Valley Radiology Group Professional Service providers and Valley Radiology
Group Imaging Service providers.  As of July 1, 1997, Valley Radiology Group
employed 24 Professional Service providers and 30 Imaging Service providers.

     Valley Radiology Group provides all of its Professional Service and
Imaging Service under fee-for-service or hospital contracts.

     At April 30, 1997, over 200,000 patients were serviced by Valley Radiology
Group annually.  Valley Radiology Group is under contract with the following
significant hospitals or health plans:  Santa Clara County Valley Medical
Center, Community Hospital of Los Gatos, Santa Teresa-Kaiser, Alexian Brothers
Hospital, Lifeguard, San Jose Medical Group and Blue Cross and Blue Shield.

MARKETING AND DEVELOPMENT

     Valley's principal marketing strategy is to combine hospitals and offices

and other independent community hospitals.  Valley has professional reading
contracts in four hospitals (approximately half of the hospitals in the area).

providers in the area are limited to one or two sites.  Valley estimates that
it has a market share of approximately 40% of all radiology services in the
area.

         VALLEY RADIOLOGY GROUP MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion relates to the historical operations of Valley
and the audited financial statements of Valley and the notes thereto appearing
elsewhere in this Prospectus/Joint Proxy Statement. For purposes of the
following discussion, medical service revenue, net represents the estimated
realizable amount to be received from patients, third party payors and others
for the provision of medical services.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1997 AS COMPARED TO THREE MONTHS ENDED MARCH 31,
1996

     Medical service revenue, net increased $0.3 million or 12% to $2.8 million
for the three months ended March 31, 1997 from $2.5 million for the three
months ended March 31, 1996 due primarily to the opening of an imaging center
subsequent to March 31, 1996.

     Costs of affiliated physician services of $1.4 million (49% of medical
service revenue, net) and $1.3 million (50% of medical service revenue, net)
for the three months ended March 31, 1997 and 1996, respectively, included
physician compensation and benefits paid or payable to owner and non-owner
physicians during the period.  The increase is related to the opening of
another imaging center subsequent to March 31, 1996.  The physician owners
determined such payments based on earnings available for distribution.

     Practice salaries, wages and benefits of $0.6 million and $0.5 million for
the three months ended March 31, 1997 and 1996, respectively, were 19% and 21%,
respectively, of medical service revenue, net.  Practice rent and lease expense
of $0.1 million for each of the three months ended March 31, 1997 and 1996,
respectively, remained consistent at 4% of medical service revenue, net.  Other
practice expenses of $0.3 million for each of the three months ended March 31,
1997 and 1996, were 12% and 13%, respectively, of medical service revenue, net.





                                      150
<PAGE>   187
  YEAR ENDED DECEMBER 31, 1996 AS COMPARED TO YEAR ENDED DECEMBER 31, 1995

     Medical service revenue, net increased $0.8 million or 8% to $11.0 million
for the year ended December 31, 1996 from $10.2 million for the year ended
December 31, 1995 due to an increase in volume of services provided as a result
of the establishment of a new facility.

     Costs of affiliated physician services of $5.4 million (49% of medical
service revenue, net) and $5.5 million (54% of medical service revenue, net)
for the years ended December 31, 1996 and 1995, respectively, included
physician compensation and benefits paid or payable to owner and non-owner
physicians during the period.  The physician owners determined such payments
based on earnings available for distribution.

     Practice salaries, wages and benefits of $2.6 million and $2.3 million for
the years ended December 31, 1996 and 1995, respectively, were 24% and 22%,
respectively, of medical service revenue, net.  Practice supplies of $0.4
million and $0.2 million for the years ended December 31, 1996 and 1995,
respectively, were 3% and 2%, respectively, of medical service revenue, net.
Practice rent and lease expense of $0.4 million and $0.5 million for the years
ended December 31, 1996 and 1995, respectively, were 4% and 5%, respectively,
of medical service revenue, net.   Depreciation and amortization expense of
$0.2 million for each of the years ended December 31, 1996 and 1995 reflects no
material changes in the composition of fixed assets or depreciation methods.
Other practice expenses of $1.3 million and $1.4 million for the years ended
December 31, 1996 and 1995, respectively, were 12% and 14%, respectively, of
medical service revenue, net.  Interest expense of $0.1 million for each of the
years ended December 31, 1996 and 1995, respectively, remained consistent at 1%
of medical service revenue, net.

                          COMPARISON OF CAPITAL STOCK

                      DESCRIPTION OF CAPITAL STOCK OF APPI

GENERAL

     The Company's authorized capital stock consists of 50,000,000 shares of
APPI Common Stock and 10,000,000 shares of Preferred Stock, par value $.0001
per share (the "Preferred Stock").

     As of the date of this Prospectus/Joint Proxy Statement and giving effect
to the Mergers and Exchanges, the conversion of the Convertible Notes, and the
completion of the Initial Public Offering, the Company will have outstanding
18,151,625 shares of APPI Common Stock (assuming an Initial Public Offering
Price of $15.00 per share) and no shares of Preferred Stock.

COMMON STOCK

     The holders of APPI Common Stock are entitled to one vote for each share
on all matters voted upon by stockholders, including the election of directors.

     Subject to the rights of any then outstanding shares of Preferred Stock,
the holders of APPI Common Stock are entitled to such dividends as may be
declared in the discretion of the Board of Directors out of funds legally
available therefor.  Holders of APPI Common Stock are entitled to share ratably
in the net assets of the Company upon liquidation after payment or provision for
all liabilities and any preferential liquidation rights of any Preferred Stock
then outstanding.  The holders of APPI Common Stock have no preemptive rights to
purchase shares of stock of the Company.  Shares of APPI Common Stock are not
subject to any redemption provisions and are not convertible into any other
securities of the Company.  All outstanding shares of APPI Common Stock are, and
the shares of APPI Common Stock being offered hereby will be, upon payment of
consideration therefor, fully paid and nonassessable.

PREFERRED STOCK

     Preferred Stock may be issued from time to time at the discretion of the
Board of Directors as shares of one or more series.  Subject to the provisions
of the Company's Restated Certificate of Incorporation and limitations
prescribed by law, the Board of Directors is expressly authorized to adopt
resolutions to issue the shares, to fix the number of shares and to change the
number of shares constituting any series, and to provide for or change the
voting powers, designations, preferences and relative, participating, optional
or other special rights, qualifications, limitations or restrictions thereof,
including dividend rights (including whether dividends are cumulative),
dividend rates, terms of redemption (including sinking fund provisions),
redemption prices, conversion rights and liquidation preferences of the shares
constituting any class or series of Preferred Stock, in each case without any
further action or vote by the stockholders.

     One of the effects of undesignated Preferred Stock may be to enable the
Board of Directors to render more difficult or to discourage an attempt to
obtain control of the Company by means of a tender offer, proxy contest, merger
or otherwise, and thereby to protect the continuity of the Company's management.
The issuance of shares of Preferred Stock pursuant to the Board of Directors'
authority described above may adversely affect the rights of the holders of APPI
Common Stock.  For example, Preferred Stock issued by the Company may have
priority over APPI Common Stock as to dividend rights, liquidation preference or
both, may have full or limited voting rights and may be convertible into shares
of APPI Common Stock.  Accordingly, the issuance of shares of Preferred Stock
may discourage bids for APPI Common Stock at a premium to, or may otherwise
adversely affect, the market price of the APPI Common Stock.

CONVERTIBLE NOTES

     The following summaries of certain provisions of the Convertible Notes and
the Registration Rights Agreement between the Company and each of the holders of
the Convertible Notes do not purport to be complete and are subject to, and are
qualified in their entirety by reference to, all provisions of the Convertible
Notes and the Registration Rights Agreement, respectively.

  GENERAL

     The Convertible Notes represent unsecured general obligations of the
Company and are convertible into APPI Common Stock as described below.  The
Convertible Notes bear interest at the annual rate of 6%, and all accrued but
unpaid interest shall be due and payable upon the closing of the Initial Public
Offering.  In the event the Convertible

Notes are not converted into APPI Common Stock by January 31, 1998, all accrued
interest is due and payable immediately and the interest rate will increase to
the prime rate as published in The Wall Street Journal plus 2% per annum
thereafter, payable quarterly.  Interest will be computed on the basis of a
360-day year comprised of 12 30-day months.  As of the date of this
Prospectus/Joint Proxy Statement, the outstanding principal amount of the
Convertible Notes was $3,500,000.

  OPTIONAL REDEMPTION

     The Convertible Notes are redeemable at the option of the Company, in whole
or in part, at the time of or any time after the Initial Public Offering on at
least 15 days' written notice, together with accrued and unpaid interest.  The
Company intends to call the Convertible Notes for redemption as soon as
practicable following the date of this Prospectus/Joint Proxy Statement.

  CONVERSION RIGHTS

     Upon receipt of written notice of redemption by the Company, the holders
may convert the principal amount of the Convertible Notes into APPI Common Stock
upon approval of the holders of at least 50% of the outstanding principal amount
of the Convertible Notes. Upon conversion, holders of the Convertible Notes will
receive shares of Common Stock at the rate of one share of Common Stock for each
$8.00 of Convertible Note principal (the "Conversion Price").  Proportional
adjustments shall be made to the conversion ratio for splits, dividends,
recapitalizations, and other distributions of the APPI Common Stock.  The
Conversion Price shall be reduced, subject to several exceptions, if the Company
sells any of its APPI Common Stock for less than $8.00 per share, to a price
determined by dividing (i) an amount equal to the sum of (A) the number of
shares of APPI Common Stock outstanding immediately prior to such sale
(including as outstanding all shares of APPI Common Stock issuable upon
conversion of Convertible Notes) multiplied by the then existing Conversion
Price, and (B) the consideration, if any, received by the Company upon such
sale, by (ii) the total number of shares of APPI Common Stock outstanding
immediately after the sale, including those issuable upon conversion of the
Convertible Notes.  No adjustment will be made to the Conversion Price for
options granted to officers, employees, directors and consultants of the Company
pursuant to any stock option plan of the Company, including the Plan.

     Each Convertible Note may be converted into shares of APPI Common Stock at
the then effective Conversion Price (i) prior to January 31, 1998, upon approval
of the holders of at least 50% of the outstanding principal amount of the
Convertible Notes following the closing of an initial public offering of APPI
Common Stock pursuant to an effective registration statement under the
Securities Act in which the aggregate gross proceeds received by the Company
equals or exceeds $10,000,000, or (ii) upon approval of the holders of at least
50% of the outstanding principal amount of the Convertible Notes on or after
January 31, 1998.

     If the Company sells shares of APPI Common Stock for less than $14.00 per
share in the Initial Public Offering, the conversion rate shall be adjusted so
that at the time of conversion the aggregate market value of the APPI Common
Stock into which the Convertible Notes are converted will equal the principal
of the Convertible Notes times 1.75.

  LOCK-UP

     Each of the holders of the Convertible Notes has entered into a lock-up
agreement with the Company, pursuant to which each such holder has agreed with
the Company not to sell the Convertible Notes or the shares of APPI Common Stock
issued or issuable upon conversion thereof owned by them at the time for a
period of 24 months following issuance of such Convertible Notes (which
Convertible Notes were issued between September 30 and December 31, 1996).  The
Company has agreed with the Underwriters not to waive this lock-up agreement for
180 days following the date of this Prospectus.

  REGISTRATION RIGHTS

     The holders of the Convertible Notes have certain registration rights upon
conversion of the Convertible Notes into APPI Common Stock.  At any time from
and after 12 months following the Initial Public Offering, and not later than
September 30, 2001, holders owning 50% or more of the aggregate of the shares
of APPI Common Stock into which any of the Convertible Notes have been or can
be converted shall have the right on one occasion to require the Company to
prepare and file a registration statement under the Securities Act covering
such shares of APPI Common Stock, and the Company, at its expense, will use its
best efforts to cause such registration statement to become effective as soon
as possible.

to the approval of the underwriter, to two "piggyback" registrations at the
Company's expense, as part of a registration by the Company of its shares of
APPI Common Stock at any time subsequent to 12 months after the date of the

       COMPARISON OF RIGHTS OF SECURITY HOLDERS OF APPI AND THE ENTITIES

     Upon consummation of the Mergers and Exchanges, the holders of Advanced

interests, Madison partnership interests, South Texas Common Stock, South Texas
No. 1 partnership interests, San Antonio Common Stock, San Antonio No. 1
partnership interests, Pacific Common Stock, TMI Common Stock, RNM Common
Stock, AIOC Common Stock, CIA Common Stock, MRIA Common Stock, Nyack Common
Stock, Pelham Common Stock, RRG Common Stock, WIC Common Stock and Valley
Common Stock will become holders of APPI Common Stock.  APPI is a Delaware
corporation and is bound by the DGCL, whereas each of the Entities is bound by
the corporate law of the state in which each such Entity was organized.  In
addition, the APPI Certificate and APPI Bylaws differ from the articles and
bylaws of each such Merger Entity (the "Corporate Governance Documents") and
the partnership agreement and other governance documents of each such Exchange
Entity (the "Partnership Governance Documents," and together with the Corporate
Governance Documents, the "Governance Documents").  The differences between the
APPI Certificate and APPI Bylaws and the Governance Documents of each Entity
and between the DGCL and the corporate law of each state in which each Entity
was organized, will ultimately result in changes in the rights of holders of
Common Stock of each of the Entities.

     The following is a summary of some of the important distinctions between
the rights of the security holders of APPI and the security holders of each of
Advanced, Ide, M&S, Lexington, Madison, South Texas, South Texas No. 1, San
Antonio, San Antonio No. 2, Pacific, TMI, RNM, AIOC, CIA, MRIA, Nyack, Pelham,
RRG, WIC and Valley.  Such description does not purport to be a complete
explanation of all such differences.  Furthermore, the identification of
specific differences is not meant to indicate that other differences do not
exist.  The following summary is also qualified in its entirety by reference to
the DGCL, the Governance Documents, the APPI Certificate and the APPI Bylaws.

LIMITATION OF DIRECTORS' OR PARTNERS' LIABILITY

     Under the DGCL, a Delaware corporation is permitted to adopt a provision
in its certificate of incorporation reducing or eliminating the liability of a
director to the corporation or its stockholders for monetary damages for a
breach of fiduciary duty as a director, provided that such liability does not
arise from certain prohibited conduct (including intentional misconduct and
breach of the duty of loyalty).  California corporations, Kansas corporations,
Maryland corporations, New York corporations and Texas corporations are
permitted to adopt similar provisions under the CCC, KGCC, MGCL, NYBCL and
TCBA, respectively.  The Texas Revised Partnership Act ("TRPA") and the Texas
Revised Limited Partnership Act ("TRPLA") similarly provide that Texas general
partnerships and Texas limited partnerships may limit the liability of a
partner to the partnership.

     The APPI Certificate provides that the liability of the directors of APPI
will be limited to the fullest extent permitted under the DGCL.  The Corporate
Governance Documents of each of Advanced, Ide, M&S, South Texas, San Antonio,
Pacific, TMI and Valley contain similar provisions limiting the liability of
the respective directors of each such Entity to the fullest extent permitted
under applicable state law.  On the other hand, the Corporate Governance
Documents of each of RNM, AIOC, CIA, MRIA, Nyack, Pelham, RRG and WIC do not
contain provisions which limit the liability of the respective directors of
each such Entity.

     The Partnership Governance Documents of Lexington limit the liability of
the General Partner to the partnership and partners of Lexington for any
actions taken in good faith by the General Partner.  However, the General
Partner of Lexington will remain liable for its willful misconduct, gross
negligence or breach of fiduciary obligations under the Lexington partnership
agreement.  The Partnership Governance Documents of Madison do not contain
provisions which limit the liability of the partners of Madison to the
partnership or to one another.  The Partnership Governance Documents of each of
South Texas No. 1 and San Antonio No. 2 limit the liability of the General
Partner of each such Entity, and the respective directors and officers of the
General Partner, to the applicable partnership and the partners of such
partnership to the fullest extent permitted under Texas law.  However, the
General Partners of South Texas No. 1 and San Antonio No. 2, and the respective
directors and officers of such General Partners, will remain liable to the
applicable partnership and the partners of such partnership to the extent that
it is proven that such persons actually derived an improper benefit from their
actions or to the extent that a judgment is rendered against any such person
based on a finding that such person's actions were the result of active and
deliberate dishonesty.





                                      158
<PAGE>   195
INDEMNIFICATION OF DIRECTORS OR PARTNERS

     Under the DGCL, a Delaware corporation may also indemnify its directors and
officers against any liabilities that they may incur in such capacities,
provided that such directors and officers have acted in good faith and in such a
manner that they reasonably believed was in, or not opposed to, the best
interests of the corporation.  California corporations, Kansas corporations,
Maryland corporations, New York corporations and Texas corporations also may
indemnify the directors and officers of such corporations under the CCC, KGCC,
MGCL, NYBCL and TBCA, respectively.  Under the TRPA, partners of a Texas general
partnership may adopt a provision in their partnership agreement which requires
such partnership to indemnify the partners for liabilities incurred in their
capacity as such, subject to any restrictions imposed by Texas law. Under the
TRLPA a Texas limited partnership may also indemnify the partners of such
partnership against any liabilities such partners may incur in such capacity,
provided that the partners have acted in good faith and in such manner that they
reasonably believed was in, or not opposed to, the best interests of such
limited partnership.

     APPI's Bylaws provide that APPI will indemnify its directors and officers
to the fullest extent permitted by the DGCL and require APPI to advance
litigation expenses upon receipt by APPI of an undertaking by a director or
officer to repay such advances if it is ultimately determined that such director
or officer is not entitled to indemnification.  The Corporate Governance
Documents of each of Advanced, Ide, M&S, South Texas, San Antonio, Pacific and
TMI provide that each such Entity will indemnify its respective directors and
officers to the fullest extent permitted under applicable state law.  The
Partnership Governance Documents of each of Lexington, South Texas No. 1 and San
Antonio No. 2 similarly provide that each such Entity will indemnify the General
Partner of each such Entity to the fullest extent permitted under Texas law.
The Madison Partnership Governance Documents provide that Madison will indemnify
its Managing Partner against reasonable expenses incurred in connection with a
pending or threatened action in which such Managing Partner is a named defendant
due to the fact that he or she is, or was, the Managing Partner of Madison, so
long as such Managing Partner is successful in the defense of such action.  On
the other hand, the Corporate Governance Documents of RNM, AIOC, CIA, MRIA,
Nyack, Pelham, RRG and WIC and Valley do not contain provisions which require
the applicable Entity to indemnify its respective directors and officers.

VOTING REQUIREMENTS

     Under the DGCL, any action requiring the approval of the stockholders of a
Delaware corporation, other than the election of directors, must be approved by
holders of a majority of shares who are present in person or represented by
proxy at a meeting of stockholders and who are entitled to vote thereon, or by
the written consent of holders of a majority of the outstanding shares of stock
entitled to vote thereon, unless the DGCL or the corporate governance documents
of such corporation provide otherwise.  Directors of a Delaware corporation may
be elected by a plurality of votes cast by holders of shares who are present in
person or represented by proxy at a meeting of stockholders and entitled to
vote on the election of directors, unless the Corporate Governance Documents
of such corporation provide otherwise.  Under the CCC, any action requiring the
approval of security holders of a California corporation, including the
election of directors, must be approved by a majority of shares represented and
voting at a duly held meeting at which a quorum is present, or by the written
consent of holders of a majority of the outstanding shares entitled to vote
thereon, unless the CCC or corporate governance documents of such corporation
provide otherwise.  Any action requiring the approval of the security holders
of a Kansas corporation, a Maryland corporation, a New York corporation or a
Texas corporation, other than the election of directors, must be approved by a
majority of shares present in person or represented by proxy at a meeting of
security holders entitled to vote on such action, or by the written consent of
holders of all of the outstanding shares entitled to vote thereon, unless the
applicable state law or the corporate governance documents of such corporation
provide otherwise.  The directors of a Kansas corporation, a Maryland
corporation, a New York corporation or a Texas corporation may be elected by a
plurality of votes cast by holders of shares entitled to vote thereon at a duly
held meeting of security holders at which a quorum is present, unless the
corporate governance documents of such corporation provide otherwise.

     Under the TRPA, the partnership agreement of a Texas general partnership
may grant voting rights on certain matters to partners and may specify the vote
required to approve such matters.  The TRLPA provides that the partnership
agreement of a Texas limited partnership may grant voting rights to the limited
partners of such partnership.  If the limited partners of a limited partnership
are granted any voting rights, then the partnership agreement of such
partnership may designate the vote required to approve an action and any other
matter relating to the exercise of the right to vote.

     APPI's Corporate Governance Documents are consistent with the DGCL with
respect to security holder voting requirements.  Likewise, the Corporate
Governance Documents of each of Advanced, South Texas, San Antonio, Pacific,
TMI, AIOC, CIA, MRIA, Nyack, Pelham, RRG, WIC and Valley are consistent with
applicable state law with respect to security holder voting requirements.  In
addition to the requirements imposed by applicable law, the Corporate





                                      159
<PAGE>   196
Governance Documents of (i) Ide provide that, unless otherwise required by New
York law, an action requiring Ide security holder approval must be approved by
three-quarters of the outstanding shares of Ide Common Stock or by the written
consent of holders of all of the outstanding Ide Common Stock; (ii) M&S provide
that, unless otherwise required by Texas law, an action requiring M&S security
holder approval generally must be approved by a majority of the outstanding
shares but certain specified actions must be approved by two-thirds of the
outstanding shares of M&S Common Stock, or by the written consent of all holders
of the outstanding M&S Common Stock; and (iii) RNM provide that, unless
otherwise required by Kansas law, an action requiring RNM security holder
approval must be approved by a majority of the outstanding RNM Common Stock,
except for a vote to approve amendments to RNM's Bylaws or to remove a director
from office, which actions require the approval of three-quarters of the
outstanding shares of RNM Common Stock.

     Under the Partnership Governance Documents (i) the General Partner of
Lexington generally may manage the affairs of Lexington, except that such
General Partner may not take certain specified actions without the approval of
one or more limited partners who own, in the aggregate, more than 50% of the
partnership interests then owned by all limited partners; (ii) the Managing
Partner of Madison may manage the affairs of Madison, except that such Managing
Partner may not take certain specified actions without the approval of partners
holding at least 66% of the partnership interests of Madison; (iii) the General
Partner of South Texas No. 1 may manage the affairs of the partnership, except
that such General Partner may not take certain actions without the approval of
one or more limited partners who own, in the aggregate, at least 66.67% of the
partnership interests then held by all of the limited partners; and (iv) the
General Partner of San Antonio No. 2 may manage the affairs of the partnership,
except that such General Partner may not take certain actions without the
approval of one or more limited partners who own, in the aggregate, at least
66.67% of the partnership interests then held by all of the limited partners.

SPECIAL MEETINGS OF SECURITY HOLDERS

     Under the DGCL, a special meeting of security holders of a Delaware
corporation may be called by the board of directors of such corporation or by
any other person authorized to do so in the corporate governance documents of
such corporation.  Notice of any such special meeting must be given not less
than ten nor more than 60 days before the date of the meeting to each security
holder entitled to vote at such meeting, unless otherwise provided in the
corporate governance documents.  In contrast, under the CCC, a special meeting
of security holders of a California corporation may be called by the board of
directors, the chairman of the board, the president, holders of shares entitled
to cast not less than ten percent of the votes at such meeting or by any other
person authorized to do so in the corporate governance documents of such
corporation.  Unless otherwise provided in the corporate governance documents
of such corporation, notice of any such meeting must be given not less than ten
nor more than 60 days before the date of the meeting to each security holder
entitled to vote at such meeting.  The KGCC, like the DGCL, provides that a
special meeting of security holders of a Kansas corporation may be called by
the board of directors or by any other person authorized to do so in the
corporate governance documents of such corporation.  Notice of any such meeting
must be given not less than ten nor more than 60 days before the date of the
meeting to each security holder entitled to vote at such meeting, unless
otherwise provided in the corporate governance documents, except that certain
special meetings, including meetings called for the purpose of voting to
approve an agreement of merger or exchange, require at least 20 days prior
notice.  Under the MGCL, a special meeting of security holders of a Maryland
corporation may be called by the board of directors, the president or any other
person authorized to do so in the corporate governance documents of such
corporation, or upon the written demand of holders of shares entitled to cast
not less than 25% of the votes at such meeting.  Notice of any such meeting
must be given not less than ten nor more than 90 days before the date of the
meeting to each security holder entitled to vote at such meeting, unless
otherwise provided in the corporate governance documents.  The NYBCL, like the
DGCL, provides that a special meeting of security holders of a New York
corporation may be called by the board of directors or any other person
authorized to do so in the corporate governance documents of such corporation.
Notice of any such meeting must be given not less than ten nor more than 50
days before the date of such meeting to each security holder entitled to vote
at such meeting, unless otherwise provided in the corporate governance
documents.  Under the TBCA, a special meeting of security holders of a Texas
corporation may be called by the board of directors, the president, any other
person authorized to do so in the corporate governance documents of such
corporation or by holders of shares entitled to cast not less than ten percent
of the votes at such meeting, unless otherwise provided in the corporate
governance documents.  Unless otherwise provided in the corporate governance
documents of such corporation, notice of any such meeting must be given not
less than ten nor more than 60 days before the date of the meeting to each
security holder entitled to vote at such meeting, except that certain special
meetings, including meetings called for the purpose of voting to approve an
agreement of merger or exchange, require at least 20 days' prior notice.

     The TRPA provides that the manner of calling a meeting of partners of a
Texas general partnership and any notice requirements for such meeting may be
established by the partners in the partnership agreement for such partnership.
Similarly, under the TRLPA, if the limited partners of a Texas limited
partnership have voting rights, then the manner





                                      160
<PAGE>   197
of calling a meeting for the partners of such partnership and any notice
requirements for such meeting may be set forth in the partnership agreement of
such partnership.

     The APPI Certificate provides that special meetings of security holders of
APPI may be called only by the APPI Board or a committee of the APPI Board
empowered to do so.  Accordingly, each of the security holders of Advanced,
Ide, M&S, South Texas, San Antonio, Pacific, TMI, RNM, AIOC, CIA, MRIA, Nyack,
Pelham, RRG, WIC and Valley will be subject to a more restrictive standard as
security holders of APPI with respect to the calling of special meetings of
security holders after each of the Mergers.  The notice requirements for any
such meeting are consistent with the notice requirements under the DGCL.  The
APPI Bylaws also establish advance notice procedures with regard to the
nomination, other than by or at the direction of the board of directors, of
persons for election as directors.  The APPI Bylaws require nominations for
the election of directors at an annual meeting to be in writing and received by
the Secretary of APPI, not less than 60 days prior to the meeting.  The notice
of nomination must set forth certain information with respect to the security
holder and each nominee for director.  Although these procedures do not give
the APPI Board any power to approve or disapprove security holder nominations
for election of directors, they may have the effect of precluding a nomination
for election of directors, if the proper procedures are not followed, and could
discourage or deter a third party from conducting a solicitation of proxies to
elect its own slate of directors, even if such solicitation might be beneficial
to APPI or its security holders.  Accordingly, these provisions may have
certain anti-takeover effects to which the security holders of each of
Advanced, Ide, M&S, South Texas, San Antonio, Pacific, TMI, RNM, AIOC, CIA,
MRIA, Nyack, Pelham, RRG, WIC and Valley and partners of each of Lexington,
Madison, South Texas No. 1 and San Antonio No. 2 are not currently subject.

     Under the Corporate Governance Documents, (i) any special meetings of
Advanced security holders may be called for any purpose upon written demand of
the holders of all of the outstanding shares entitled to vote at such meeting
and the notice of any such meeting is required to be delivered not less than 20
nor more than 60 days before the date of the meeting, (ii) any special meetings
of Ide security holders may be called for any purpose by the Ide Board, the
president or upon written demand of the holders of not less than 25% of all of
the outstanding shares entitled to vote at such meeting and the notice of any
such meeting is required to be delivered not less than ten days nor more than 50
days before the date of the meeting, (iii) any special meetings of M&S security
holders may be called for any purpose by the M&S Board, the president or by
holders of not less than ten percent of all of the outstanding shares entitled
to vote at such meeting and the notice of any such meeting is required to be
delivered not less than ten days nor more than 60 days before the date of the
meeting, except that certain special meetings, including meetings called for the
purpose of voting to approve an agreement of merger or exchange, require at
least 20 days' prior notice, (iv) any special meetings of South Texas security
holders may be called for any purpose by the South Texas Board, the president or

San Antonio security holders may be called for any purpose by the San Antonio
Board, the president or by holders of not less than ten percent of all of the

before the date of the meeting, unless otherwise provided by Texas law, (vi) any
special meetings of Pacific security holders may be called for any purpose by
the Pacific Board, the chairman of the board, the president or any
vice-president or by holders of at least ten percent of all of the outstanding
shares entitled to vote at such meeting and the notice of any such meeting is
required to be delivered not less than 35 nor more than 60 days before the date
of the meeting, (vii) any special meetings of TMI security holders may be called

Agreement of Merger to which RNM is a party, require at least 20 days' prior
notice, (ix) any special meetings of AIOC security holders may be called for any
purpose by the AIOC Board, the president or upon written demand of the holders

less than ten days nor more than 50 days before the date of the meeting, (x) any

     Under the Partnership Governance Documents, (i) any meeting of the partners
of Lexington may be called by the General Partner or by one or more limited
partners who own, in the aggregate, more than 50% of the partnership interests
held by all limited partners of Lexington and notice of any such meeting must be
given not less than three nor more than 30 days from the date of such meeting;
(ii) any meeting of the partners of South Texas No. 1 may be called by the

any such meeting must be given not less than five nor more than 60 days before
the date of such meeting; and (iii) any meeting of the partners of San Antonio
may be called by the General Partner or upon the written demand of one or more
limited partners who own, in the aggregate, at least 15% of the partnership
interests of San Antonio and notice of any such meeting must be given not less
than five nor more than 60 days before the date of such meeting.  The Madison
Partnership Governance Documents do not contain any provisions relating to who
may call a special meeting of partners or what notice, if any, must be given to
partners prior to such a meeting.

SIZE OF THE BOARDS OF DIRECTORS

     The DGCL permits the board of directors of a Delaware corporation to change
the authorized number of directors by an amendment to the bylaws or in the
manner provided in the bylaws, unless the number of directors is fixed in the
certificate of incorporation of such corporation, in which case a change in the
number of directors may be made only by an amendment of the certificate of
incorporation.  Under the CCC, although changes in the number of directors
generally must be approved by the shareholders, the board of directors may fix
the exact number of directors within a stated range set forth in the articles of
incorporation or bylaws.  The KGCC, like the DGCL, permits the board of
directors of a Kansas corporation to change the authorized number of directors
by an amendment to the bylaws or in the manner specified in the bylaws, unless
the number of directors is fixed in the articles of incorporation, in which case
a change in the number of directors may only be made by an amendment of the
articles of incorporation.  Under the MGCL, the bylaws of a Maryland corporation
may empower a majority of the entire board of directors to alter within
specified limits the number of directors fixed in the corporate governance
documents of such corporation.  Under the NYBCL, a New York corporation may
authorize its board of directors to change the number of directors by an
amendment to the bylaws of such corporation or in the manner specified in such
bylaws, provided that such change in the number of directors is approved by a
majority of the entire board of directors.  The TBCA, like the DGCL, permits the
board of directors of a Texas corporation to change the authorized number of
directors by an amendment to the bylaws or in the manner specified in the
bylaws, unless the number of directors is set forth in the articles of
incorporation of such corporation, in which case a change in the number of
directors may be made only by an amendment of the articles of incorporation.

     The number of directors of APPI is currently fixed at seven.  The APPI
Bylaws provide that the number of directors may be changed by resolution of the
Board of Directors or by the security holders of APPI at an annual meeting of
security holders.

     The Corporate Governance Documents of each of the respective Merger
Entities provide that (i) the number of directors on the Advanced Board may be
increased or decreased by the affirmative vote of the holders of a majority
of the outstanding shares of Advanced Common Stock; (ii) the number of
directors on the Ide Board may be increased or decreased by an amendment to the
Ide Bylaws adopted by holders of three-quarters of the outstanding shares of
Common Stock or by three-quarters of the directors then in office; (iii) the
number of directors on the M&S Board may be increased or decreased only by an
amendment to the M&S Bylaws adopted by the affirmative vote of the holders of
two-thirds of the shares of M&S Common Stock present or represented at such
meeting and entitled to vote thereat; (iv) the number of directors on the South
Texas Board may be increased or decreased only by an amendment to the South
Texas Bylaws adopted by the affirmative vote of the holders of a majority of
the shares of South Texas Common Stock





                                      162
<PAGE>   199
entitled to vote thereon or by the South Texas Board; (v) the number of
directors on the San Antonio Board may be increased or decreased only by an
amendment to the San Antonio Bylaws adopted by the affirmative vote of the
holders of a majority of the shares of San Antonio Common Stock entitled to vote
thereon or by the San Antonio Board; (vi) the number of directors on the Pacific
Board may be fixed by a resolution of the Pacific Board so long as such number
is within the stated range set forth in the Pacific Bylaws, which stated range
may only be changed by an amendment of the Bylaws adopted by the affirmative
vote of the holders of a majority of the outstanding shares of Pacific Common
Stock or the Pacific Board; (vii) the number of directors on the TMI Board may
be fixed by a resolution of the TMI Board so long as such number is within the
stated range set forth in the TMI Bylaws, which stated range may only be changed
by an amendment of the Bylaws adopted by the affirmative vote of the holders of
a majority of the outstanding shares of TMI Common Stock or the TMI Board;
(viii) the number of directors on the RNM Board may be increased or decreased by
the affirmative vote of the holders of a majority of the outstanding shares of
RNM Common Stock to amend RNM's Corporate Governance Documents to provide for
such change; (viii) the number of directors on the AIOC Board may be increased
or decreased only by an amendment of the AIOC Bylaws adopted by a majority of
the outstanding shares entitled to vote thereon, or by the AIOC Board; (ix) the
number of directors on the CIA Board may be increased or decreased only by an
amendment of the CIA Bylaws adopted by a majority of the outstanding shares
entitled to vote thereon, or by the CIA Board; (x) the number of directors on
the MRIA Board may be increased or decreased only by an amendment of the MRIA
Bylaws adopted by a majority of the outstanding shares entitled to vote thereon,
or by the MRIA Board; (xi) the number of directors on the Nyack Board may be
increased or decreased only by an amendment of the Nyack Bylaws adopted by a
majority of the outstanding shares entitled to vote thereon, or by the Nyack

decreased only by an amendment of the Pelham Bylaws adopted by a majority of the
outstanding shares entitled to vote thereon, or by the Pelham Board; (xiii) the
number of directors on the RRG Board may be increased or decreased only by an
amendment of the RRG Bylaws adopted by a majority of the outstanding shares
entitled to vote thereon, or by the RRG Board; (xiv) the number of directors on
the WIC Board may be increased or decreased only by an amendment of the WIC
Bylaws adopted by a majority of the outstanding shares entitled to vote thereon,
or by the WIC Board; and (xv) the number of directors on the Valley Board may be
increased or decreased only by an amendment of the Valley Bylaws adopted by the
affirmative vote of the holders of a majority of the outstanding shares of
Valley Common Stock.

CUMULATIVE VOTING FOR DIRECTORS

     Under the DGCL, security holders of a Delaware corporation do not have the
right to cumulate their votes in the election of directors unless the
certificate of incorporation of such corporation specifically provides for
cumulative voting in the election of directors.  In an election of directors
under cumulative voting, each share of stock normally having one vote is
entitled to a number of votes equal to the number of directors to be elected.
A security holder may then cast all such votes for a single candidate or may
allocate them among as many candidates as the security holder sees fit.  The
KGCC and NYBCL contain similar provisions to those found in the DGCL with
respect to the ability of security holders to cumulate their votes in the
election of directors.  In contrast, the CCC provides that security holders of
a California corporation are entitled to cumulate their votes in the election
of directors upon proper notice to such corporation of their intention to do
so.  However, a California corporation with (1) outstanding securities listed
on the New York or American Stock Exchange or (2) a class of securities
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. may eliminate
security holders' cumulative voting rights pursuant to the CCC.  Security
holders of a Maryland corporation also have cumulative voting rights in the
election of directors under the MGCL.  Similarly, under the TBCA, security
holders of a Texas corporation are entitled to cumulate their votes in the
election of directors upon proper notice to such corporation of their intention
to do so, unless the articles of incorporation of such corporation provide
otherwise.

     APPI has not provided for cumulative voting in the APPI Certificate.
Accordingly, security holders of APPI do not have cumulative voting rights with
respect to the election of directors.  Similarly, Ide, RNM, AIOC, CIA, MRIA,
Nyack, Pelham, RRG and WIC have not provided for cumulative voting in their
respective Corporate Governance Documents and, thus, the security holders of
each such Entity do not have cumulative voting rights with respect to the
election of directors.  The Corporate Governance Documents of M&S expressly
eliminate the ability of the holders of M&S Common Stock to cumulative votes in
the election of directors.  On the other hand, security holders of Advanced,
South Texas, San Antonio, Pacific, TMI and Valley have the right to cumulate
votes with respect to the election of their respective directors under
applicable state law.

REMOVAL OF DIRECTORS

     Under the DGCL, any or all of the directors of a Delaware corporation that
does not have a classified board of directors may be removed, with or without
cause, by the holders of a majority of the shares entitled to vote at an
election of directors, unless the corporate governance documents of such
corporation require a supermajority vote to remove directors.  If, however, the
security holders of such corporation have cumulative voting rights with respect
to





                                      163
<PAGE>   200
the election of directors, then no director may be removed (unless the entire
board is removed) if the number of votes cast against the removal of such
director would be sufficient to elect the director under cumulative voting. The
CCC, KGCC, MGCL and TBCA contain provisions relating to the removal of directors
that are substantially similar to the provisions of the DGCL.  Under the NYBCL,
any or all of the directors of a New York corporation that does not have a
classified board of directors may be removed for cause and, if the corporate
governance documents of such corporation so provide, without cause, by the
holders of a majority of shares entitled to vote at an election of directors,
unless the corporate governance documents of such corporation require a
supermajority vote to remove directors. If, however, the security holders of
such corporation have cumulative voting rights with respect to the election of
directors, then no director may be removed (unless the entire board is removed)
if the number of votes cast against the removal of such director would be
sufficient to elect the director under cumulative voting.

     The APPI Corporate Governance Documents do not require a supermajority vote
by security holders to remove directors from the APPI Board.  Accordingly, the
APPI directors may be removed in accordance with the provisions of the DGCL. The
Corporate Governance Documents of each of the Merger Entities provide that (i)
member of the Advanced Board may be removed with [or without] cause by the
holders of a majority of the shares entitled to vote thereon; (ii) a member of
the Ide Board may be removed, with or without cause, by the affirmative vote of
the holders of not less than three-quarters of the issued and outstanding shares
entitled to vote at an election of directors or by three-quarters of the entire
Ide Board; (iii) a member of the M&S Board may be removed, with or without
cause, by the affirmative vote of the holders of not less than two-thirds of the
outstanding shares entitled to vote at an election of directors; (iv) a member
of the South Texas Board may be removed, with or without cause, by the
affirmative vote of the holders of a majority of the outstanding shares entitled
to vote at an election of directors; (v) a member of the San Antonio Board may
be removed, with or without cause, by the affirmative vote of the holders of a
majority of the outstanding shares entitled to vote at an election of directors;
(vi) a member of the Pacific Board may be removed, with or without cause, by the
affirmative vote of the holders of not less than a majority of the outstanding
shares entitled to vote at an election of directors, provided, however, that no
director may be removed if the votes cast against such director's removal would
be sufficient to elect such director under cumulative voting; (vii) a member of
the TMI board may be removed, with or without cause, by the affirmative vote of
the holders of not less than a majority of the outstanding shares entitled to
vote at an election of directors, provided, however, that no director may be
removed if the votes cast against such director's removal would be sufficient to
elect such director under cumulative voting; (viii) a member of the RNM Board
may be removed, with or without cause, by the affirmative vote of the holders of
not less than three-quarters of the outstanding shares entitled to vote at an
election of directors; (ix) a member of the AIOC Board may be removed with cause
by the affirmative vote of holders of a majority of shares entitled to vote
thereon or by the AIOC Board, but such member may only be removed without cause
by the affirmative vote of holders of a majority of shares entitled to vote
thereon; (x) a member of the CIA Board may be removed with cause by the
affirmative vote of holders of a majority of shares entitled to vote thereon or
by the CIA Board, but such member may only be removed without cause by the
affirmative vote of holders of a majority of shares entitled to vote thereon;
(xi) a member of the MRIA Board may be removed with cause by the affirmative
vote of holders of a majority of shares entitled to vote thereon or by the MRIA
Board, but such member may only be removed without cause by the affirmative vote
of holders of a majority of shares entitled to vote thereon; (xii) a member of
the Nyack Board may be removed with cause by the affirmative vote of holders of
a majority of shares entitled to vote thereon or by the Nyack Board, but such
member may only be removed without cause by the affirmative vote of holders of a
majority of shares entitled to vote thereon; (xiii) a member of the Pelham Board
may be removed with cause by the affirmative vote of holders of a majority of
shares entitled to vote thereon or by the Pelham Board, but such member may only
be removed without cause by the affirmative vote of holders of a majority of
shares entitled to vote thereon; (xiv) a member of the RRG Board may be removed
with cause by the affirmative vote of holders of a majority of shares entitled
to vote thereon or by the RRG Board, but such member may only be removed without
cause by the affirmative vote of holders of a majority of shares entitled to
vote thereon; (xv) a member of the WIC Board may be removed with cause by the
affirmative vote of holders of a majority of shares entitled to vote thereon or
by the WIC Board, but such member may only be removed without cause by the
affirmative vote of holders of a majority of shares entitled to vote thereon;
and (xvi) a member of the Valley Board may be removed, with or without cause, by
holders of a majority of shares entitled to vote at an election of directors.





                                      164
<PAGE>   201
AMENDMENTS TO THE GOVERNANCE DOCUMENTS

     The DGCL provides that a Delaware corporation may amend its certificate of
incorporation so long as a proposed amendment is approved (i) first by the
board of directors and (ii) then by a majority of the total outstanding stock
entitled to vote thereon and a majority of the outstanding stock of each class
entitled to vote thereon, unless the certificate of incorporation requires a
super-majority vote.  The provisions of the CCC, KGCC and NYBCL relating to
amendments of the articles or certificate of incorporation of a corporation, as
the case may be, are substantially similar to the provisions of the DGCL.  In
contrast, under the MGCL and TBCA, an amendment of the articles of
incorporation must be approved (i) first by the board of directors and (ii)
then by holders of two-thirds of the total outstanding shares entitled to vote
thereon and by holders of at least two-thirds of the shares within each class
of outstanding shares entitled to vote thereon, unless the articles of
incorporation require the vote of a larger proportion of the total outstanding
shares or any class thereof.

     The APPI Certificate does not contain supermajority voting requirements
with respect to amendments of the APPI Certificate.  Accordingly, holders of a
majority of the outstanding APPI Common Stock may amend the APPI Certificate.
The articles or certificate of incorporation, as the case may be, of each of
Pacific, TMI, RNM, AIOC, CIA, MRIA, Nyack, Pelham, RRG, WIC and Valley also do
not contain supermajority voting requirements, and, thus, holders of a majority
of the outstanding Common Stock of each such Entity may also amend such Entity's
applicable articles or certificate of incorporation.  The articles of Advanced,
M&S, South Texas and San Antonio also do not impose greater voting requirements
for the amendment of such Entity's articles than those imposed by applicable
state law.  Accordingly, amendments to the articles of each such Entity may be
made by holders of two-thirds of the outstanding Common Stock of such Entity.
However, Ide's certificate of incorporation does impose a greater voting
requirement than that imposed by the NYBCL.  Holders of at least three-quarters
of the outstanding shares of Ide Common Stock must approve certain amendments to
the Ide certificate of incorporation.

     Under the DGCL, the bylaws of a Delaware corporation may be amended only
by the stockholders of such corporation, unless the corporate governance
documents of such corporation expressly authorize the board of directors to
amend the bylaws as well.  The provisions of the KGCC, MGCL and NYBCL relating
to amendment of a corporation's bylaws are substantially similar to the
provisions of the DGCL.  In contrast, bylaws of a California corporation or a
Texas corporation may be amended by either the security holders or the board of
directors of such corporation under the CCC and TBCA, respectively.  However,
the corporate governance documents of a California corporation or Texas
corporation may restrict or eliminate the power of the board of directors to
amend the bylaws of such corporation.

     The APPI Certificate does not expressly authorize the APPI Board to amend
the APPI Bylaws.  Accordingly, only the security holders of APPI may amend the
APPI Bylaws.  Under the Corporate Governance Documents of each of the Entities,
(i) the Bylaws of Advanced may be amended by the affirmative vote of the holders
of at least a majority of the outstanding shares of Advanced Common Stock with
the consent of (ii) the Ide Bylaws may be amended by the affirmative vote of the
holders of three-quarters of the outstanding shares of Ide Common Stock entitled
to vote thereon or by the vote of three-quarters of the entire board of
directors, (iii) the M&S Bylaws may be amended by the affirmative vote of the
holders of two-thirds of the outstanding shares of M&S Common Stock, (iv) the
South Texas Bylaws may be amended by the affirmative vote of the holders of a
majority of the outstanding shares of South Texas Common Stock or by the South
Texas Board, (v) the San Antonio Bylaws may be amended by the affirmative vote
of the holders of a majority of the outstanding shares of San Antonio Common
Stock or by the San Antonio Board, (vi) the Pacific Bylaws may be amended by the
affirmative vote of the holders of a majority of the outstanding shares of
Pacific Common Stock or by the Pacific Board, subject to certain restrictions,
(vii) the TMI Bylaws may be amended by the affirmative vote of the holders of a
majority of the outstanding shares of TMI Common Stock or by the TMI Board,
subject to certain restrictions, (viii) the RNM Bylaws may be amended by the
affirmative vote of the holders of three-quarters of the outstanding shares of
RNM Common Stock, (ix) the AIOC Bylaws may be amended by holders of a majority
of the shares entitled to vote thereon or by the AIOC Board, (x) the CIA Bylaws
may be amended by holders of a majority of the shares entitled to vote thereon
or by the CIA Board, (xi) the MRIA Bylaws may be amended by holders of a
majority of the shares entitled to vote thereon or by the MRIA Board, (xii) the
Nyack Bylaws may be amended by holders of a majority of the shares entitled to

DISSOLUTION

     Under the DGCL, a dissolution of a Delaware corporation must be approved
by security holders holding 100% of the total voting power of such corporation,
unless the board of directors initiated and approved the proposal to dissolve,
in which case the dissolution may be approved by a simple majority of the
outstanding shares of capital stock entitled to vote thereon.  Under the CCC,
security holders holding 50% or more of the total voting power of a California
corporation may authorize the dissolution of such corporation, with or without
the approval of the board of directors, and this right may not be modified by
the articles of incorporation.  The KGCC provides that the dissolution of a
Kansas corporation must be approved (i) first by a resolution adopted by a
majority of the entire board of directors declaring such dissolution to be
advisable and (ii) then by the affirmative vote of a majority of the
outstanding shares entitled to vote thereon.  Similarly, the MGCL provides that
a Maryland corporation may be dissolved only if it is approved (i) first by the
affirmative vote of a majority of the entire board of directors and (ii) then
by the affirmative vote of two-thirds of all the outstanding shares entitled to
vote thereon.  Under the NYBCL, a New York corporation may be dissolved only
with the approval of two-thirds of all outstanding shares entitled to vote
thereon, unless the certificate of incorporation of such corporation provides
otherwise.  The certificate of incorporation may provide that any security
holder, or the holders of any specified number or proportion of shares may
require the dissolution of such corporation at will or upon the occurrence of
any specified event.  Under the TBCA, a corporation may be dissolved upon the
affirmative vote of the holders of at least two-thirds of the outstanding
shares of the corporation after the board of directors adopts a resolution
recommending that the corporation be dissolved.

     Under the TRPA, partners of a Texas general partnership may adopt a
provision in their partnership agreement which provides that the partnership
must dissolve upon the expiration of a specified term or the completion of a
particular undertaking or upon the occurrence of a specified event.  If the
partnership agreement of such partnership does contain such a provision, then
such partnership must dissolve (i) as specified in the partnership agreement,
unless the partners vote to continue the partnership, or (ii) if all of the
partners elect to dissolve.  If the partnership agreement does not contain any
such provision, then the partnership may be dissolved at the express will of
holders of a majority of the partnership interests of such partnership.  Under
the TRLPA, a Texas limited partnership must dissolve on (i) the occurrence of
an event which the partnership agreement specifies will cause the dissolution
of such partnership; (ii) the written consent of all of the partners; (iii) the
withdrawal of a General Partner or such partnership; or (iv) the entry of a
decree of judicial dissolution.  The Lexington partnership agreement provides
that Lexington will be dissolved upon the occurrence of certain specified
events or if all of the partners consent in writing to the dissolution of the
partnership.  The Madison partnership agreement provides that Madison may be
dissolved at any time upon the agreement of partners holding at least 66% of
the partnership interests of Madison.  The partnership agreement of each of
South Texas No. 1 and San Antonio No. 2 provides that each such partnership
will be dissolved upon the occurrence of certain specified events, or if the
General Partner and limited partners holding at least two-thirds of the
partnership interests then held by all limited partners of such partnership
consent in writing to the dissolution of such partnership.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of
American Physician Partners, Inc.:
 
     We have audited the accompanying balance sheet of American Physician
Partners, Inc. -- A Development Stage Company (a Delaware corporation) as of
December 31, 1996, and the related statements of income, stockholders' deficit,
and cash flows for the period from inception (April 30, 1996) to December 31,
1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of American Physician Partners,
Inc. -- A Development Stage Company as of December 31, 1996, and the results of
its operations and its cash flows for the period from inception (April 30, 1996)
to December 31, 1996, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
1. DESCRIPTION OF BUSINESS:
 
     American Physician Partners, Inc. -- A Development Stage Company (the
"Company"), a Delaware corporation, is a radiology practice management entity.
The Company is a development stage company which through December 31, 1996, had
no revenue or significant operations. During the period from inception (April
30, 1996) to December 31, 1996, the Company reported a net loss of approximately
$1.6 million primarily as a result of general and administrative expenses
incurred during its startup and organizational stage. The Company's operating
prospects are dependent upon a number of factors including the ability to
attract physicians to its business concept and integrate their operations,
competition from similar entities as the Company and overall trends in the
healthcare industry (including the effects of government regulation and
reimbursement trends).
 
2. SIGNIFICANT ACCOUNTING POLICIES:
 
  Basis of Presentation
 
     The financial statements have been prepared on the accrual basis of
accounting and include the accounts of the Company.
 
     The Company's financial statements have been prepared in anticipation of an
initial public offering of the Company's common stock (the "offering").
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with original
maturities of three months or less when purchased to be cash equivalents.
 
  Property and Equipment
 
     Property and equipment, consisting of furniture, fixtures, and equipment,
are stated at cost. Depreciation is calculated using the straight-line method
over the estimated useful lives of the assets (five years).
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Basis of Presentation -- Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim period from January 1, 1997, to March 31,

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
1997, has been included herein. The results of operations for the interim period
is not necessarily indicative of the results for the full year.
 
3. CONVERTIBLE NOTES PAYABLE:
 
     During 1996, the Company issued $3,500,000 in convertible notes (the
"Notes"). As of December 31, 1996, $40,000 and $357,000 of the Notes are held by
employees and shareholders, respectively. The interest rate on the Notes is 6%
and they mature on January 31, 1998. The Notes may, at the election of the
noteholders of at least 50% of the outstanding principal amount, be converted
into shares of common stock at a conversion price of $8 per share, subject to
certain limitations, as defined in the Note agreement. In addition, upon or
after the effective date of the offering, the Company may redeem the Notes at
par in whole or in part.
 
     If the Notes remain outstanding at January 31, 1998, the interest rate
increases to the prime rate plus 2% per annum.
 
     The Company issued $400,000 in notes to stockholders during 1996. The
interest rate on these notes was the bank base lending rate. These notes were
paid in full prior to December 31, 1996.
 
4. COMMON STOCK AND STOCK OPTION PLAN:
 
  Common Stock
 
     During 1996, the Company's Board of Directors issued 2,000,000 shares of
common stock. No shares of stock were held by employees at December 31, 1996.
 
  Stock Option Plan
 
     During 1996, the Company's Board of Directors approved a Stock Option Plan
(the "Plan") under which 3,000,000 options to purchase shares of the Company's
common stock may be granted to key directors, employees and other health care
professionals associated with the Company, as defined by the Plan. Options
granted under the Plan may be either incentive stock options (ISO) or
nonqualified stock options (NQSO). The option price per share under the Plan may
not be less than 100% of the fair market value at the grant date for ISO and may
not be less than 85% of the fair market value at the grant date for NQSO.
Generally, options vest over a 5-year period.
 
     The Company accounts for its stock-based compensation arrangements under
the provisions of Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" (APB No. 25). In 1995, Financial Accounting Standards
Board Statement No. 123, "Accounting for Stock-Based Compensation" (FASB No.
123), was issued, whereby companies may elect to account for stock-based
compensation using a fair value based method or continue measuring compensation
expense using the intrinsic value method prescribed in APB No. 25. FASB No. 123
requires that companies electing to continue to use the intrinsic value method
make pro forma disclosure of net income and net income per share as if the fair
value based method of accounting had been applied.
 
     The pro forma effects of adopting FASB No. 123's fair value based method
for the period ended December 31, 1996 were not materially different from the
corresponding APB No. 25 intrinsic value methodology because the weighted
average grant-date fair value of options granted during the period was
negligible. However, the effects of applying FASB No. 123 during 1996 are not
likely to be representative of the effects on pro forma net income for future
years because the vesting of options will cause additional incremental expense
to be recognized in future periods.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     As of December 31, 1996, 1,210,000 options were granted and 1,790,000
options were available to be granted under the Plan. The weighted average
exercise prices for total granted options and total exercisable options were
$.74 and $.20, respectively, at December 31, 1996. The following table
summarizes information for the significant option groups outstanding at December
31, 1996:

   8.00        95,000        10               917
</TABLE>
 
     Upon the effective date of the offering, the vesting period of 480,000
options will accelerate.
 
5. NET LOSS PER SHARE:
 
     Net loss per share is computed by dividing net loss by the number of common
stock and common stock equivalent shares outstanding during the periods in
accordance with the applicable rules of the Securities and Exchange Commission
("SEC"). All common stock and common stock options issued in the year prior to
the offering have been considered as outstanding common stock equivalents under
the treasury stock method, based on an estimate of the offering price. Shares of
common stock issuable upon conversion of the Notes are assumed to be common
stock equivalent shares for all periods presented.
 
     In February, 1997, the Financial Accounting Standards Board issued
Statement No. 128 "Earnings per Share," which specifies the computations,
presentation, and disclosure requirements for earnings per share for entities
with publicly held common stock or potential common stock. The following pro
forma amounts indicate earnings per share as if computed in accordance with this
new statement.

6. INCOME TAXES:
 
     The Company has incurred losses since inception. At December 31, 1996, the
Company has a net operating loss carryforward for income tax purposes of
approximately $1,647,000 available to reduce future amounts of taxable income.
If not utilized to offset future taxable income, the net operating loss
carryforward will expire in 2011.
 
     The deferred tax benefit of approximately $600,000 generated during 1996
has been fully offset by a valuation allowance. The Company has recorded a full
valuation allowance against its deferred tax asset because of the Company's
current financial condition, its limited operating history, and its operating
losses recorded to date. If the Company does achieve profitability in the
future, the valuation allowance will be reduced by a credit to income.
 
7. DISCLOSURES ABOUT THE FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107, "Disclosures About
Fair Value of Instruments," requires disclosure about the fair value of
financial instruments. The carrying amounts and the estimated fair values for
these financial instruments as of December 31, 1996, were as follows:

9. SUBSEQUENT EVENTS:
 
     The Company plans to reorganize and complete an initial public offering. As
part of this transaction, certain assets and liabilities of seven radiology
practices (the "Founding Affiliated Practices") will be exchanged for the
Company's common stock and cash. The exchange will be accounted for at the
historical cost basis with the stock being valued at the historical cost of the
net assets exchanged. The cash payments to the owners of the Founding Affiliated
Practices will be reflected as dividends paid by the Company. Concurrent with
these exchanges, the physicians will create new medical professional
corporations (PC's) which will enter into 40-year service agreements with the
Company. Additionally, all physicians will enter into employment and noncompete
agreements with the new PC's.
 
     As of the closing date, the Company will agree to pay the owners of the
Founding Affiliated Practices amounts equal to their existing cash and net
accounts receivable, less certain accounts payable and accrued liabilities of
the Founding Affiliated Practices.
 
     The following summarized unaudited pro forma information assumes the
exchange between the Company and the Founding Affiliated Practices, but does not
give effect to the offering. This pro forma information assumes the exchanges
occurred on March 31, 1997, for balance sheet purposes and on January 1, 1996,
for income statement purposes (in thousands):

Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Advanced Radiology, LLC and

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        DECEMBER 31, 1994, 1995 AND 1996
 
1. BUSINESS, ORGANIZATION AND BASIS OF PRESENTATION:
 
     Advanced Radiology, LLC (the "Company") is a Maryland limited liability
company organized to provide radiology and imaging healthcare services. Its
offices are located in the Baltimore, Maryland, metropolitan area. The Company
was organized in October 1994 and began providing healthcare services in January
1995.
 
     The consolidated financial statements include the accounts of the Company
and its seventy-three percent owned subsidiary, MRI at St. Joseph Medical
Center, LLC ("MRI"). All significant intercompany accounts and transactions have
been eliminated in consolidation.
 
     The Company was formed through the merger of five existing radiology
practices -- Drs. Copeland, Hyman, and Shackman, P.A. ("Copeland"); Drs. Thomas,
Wallop, Kim, and Lewis, P.A. ("Arundel"); Diagnostic Imaging Associates, P.A.
(DIAPA); Drs. DeCarlo, Lyon, Hearn, and Pazourek, P.A. ("DeCarlo"); and Carroll
Imaging Associates, P.A. ("Carroll") (collectively, the "Practices"). Effective
January 1, 1995, the Practices contributed certain assets (primarily fixed
assets and investments in joint ventures) and the debt related to those assets
in exchange for ownership interests in the Company.
 
     The initial formation of the Company has been accounted for using purchase
accounting under the provisions of APB No. 16. Based on the asset sizes of the
individual contributed radiology practices, Copeland was identified as the
acquirer, and accordingly, all balances prior to January 1, 1995, represent the
activities of Copeland on a stand alone basis. The assets contributed by
Arundel, DIAPA, DeCarlo, and Carroll were recorded at the estimated fair value
of the assets contributed and liabilities assumed. Following are the assets and
liabilities, by practice.

     In addition, as part of the initial formation of the Company, all of the
assets and liabilities of Copeland, other than fixed assets, debt, and certain
miscellaneous assets, were maintained by Copeland and were not contributed to
the Company. Net assets in the amount of $6,471,600 (consisting primarily of
accounts receivable) were not contributed to the Company by Copeland. This
amount, less the $561,382 described above, has been reflected as a distribution
in the accompanying consolidated statements of owners' equity.
 
     Each of the Practices received Class B membership interests in the Company.
Such Class B interests represent in excess of 99% of the Company's ownership.
The Class A members are approximately 50 physicians, each owning an .01%
interest. The Class B members appoint the Management Committee, which has the
authority to manage regular operations of the Company.

     In April 1996, Harbor Radiologists, P.A. ("Harbor") was admitted as a
14.30% Class B member of the Company. Its shareholders were also admitted as
Class A members. The estimated fair market values of assets and liabilities
contributed by Harbor in exchange for an interest in the Company are as follows:

</TABLE>
 
     The accompanying consolidated financial statements have been prepared on
the accrual basis of accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with maturities of
three months or less when purchased to be cash equivalents.
 
  Accounts Receivable
 
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payors for medical services
provided by physicians. Such amounts are reduced by an allowance for contractual
adjustments and other uncollectible amounts.
 
  Property and Equipment
 
     Property and equipment is recorded at cost. Depreciation on furniture,
fixtures and equipment is computed using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are amortized on
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Investments in Affiliated Entities
 
     Investments in joint venture partnerships are accounted for using the
equity method. In addition, the Company holds two investments in entities
accounted for under the cost method.
 
  Other Assets
 
     Other assets include loan origination costs, organization costs, deposits
and other assets. Loan origination costs are being amortized on a straight-line
basis over a four-year period. Organizations costs are being amortized on a
straight-line basis over a five-year period.
 
  Medical Service Revenues
 
     Medical service revenue are accounted for in the period in which the
services are provided. The revenue are reported at the estimated realizable
amounts from patients, third party payors and others. Provisions for estimated
third party payor adjustments are estimated and recorded in the period the
related services are provided. Any adjustment to the amounts is recorded in the
period in which the revised amount is determined. A significant portion of the
Company's medical service revenue are related to Medicare and other
 
                                      F-18

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
governmental programs. Medicare and other governmental programs reimburse
physicians based on fee schedules which are determined by the related
governmental agency. Additionally, the Company participates in agreements with
managed care organizations to provide services at negotiated rates.
 
  Costs of Affiliated Physician Services
 
     Costs of Affiliated Physician Services include all compensation to
non-owner physicians, as well as certain benefits, educational and travel costs
paid to non-owner and owner physicians. All owner physicians are employed by the
Practices, thus distributions of equity are made by the Company to the
Practices, who then pay all owner physician salaries.
 
  Income Taxes
 
     There is no provision for income taxes in the accompanying consolidated
financial statements. The members include their respective share of Company
profits and losses in their individual and corporate tax returns. In 1994,
Copeland was an S corporation, and accordingly, all profits and losses were
reported by the individual physicians in their individual and corporate returns.
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Basis of Presentation -- Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim periods from January 1, 1996, to March 31, 1996, and from
January 1, 1997, to March 31, 1997, have been included herein. The results of
operations for the interim periods are not necessarily indicative of the results
for the full year.
 
3. INVESTMENTS IN AFFILIATED ENTITIES:
 
     In 1995, investments in affiliated entities consist of 50% interests in two
partnerships (Franklin Imaging Joint Venture ("Franklin") and Advanced Imaging
of Carroll County Limited Partnership (AICC)), which perform radiology and
imaging healthcare services, and 50% of the common stock of a corporation
(Advanced Medical Imaging, Inc. (AMI)) which enters into and administers managed
care contracts for radiology services.

purposes with Mercantile Safe Deposit and Trust Company ("Mercantile"). At
December 31, 1996, the Company had $4,000,000 outstanding under the line. In
addition, the Company has a $15,000,000 revolving credit facility with
Mercantile for equipment purchases. Advances under the credit facilities bear
interest at bank's prime rate, payable monthly. The interest rate at December
31, 1996, was 8.25%. The maturity date is July 3, 1997 or on such later date as
the bank may elect; however, on an annual basis, the bank may approve a one-year
extension. Advances under the credit facility, when combined with any
outstanding balances on two of the term loan note payables described above, are
limited to $20,000,000 in total. At December 31, 1996, the maximum amount of
funds available under the credit facility approximated $8,200,000. Advances are
collateralized by a first lien on all assets of the Company and the guarantees
of the five Class B members.
 
     In connection with the term and revolving credit facility to Mercantile,
the Company is required to maintain a liabilities to net worth ratio not
exceeding 1 to 1, and a minimum cash flow coverage ratio of at least 1.25 to 1.
In addition, the agreement provides that at no time shall total debt to
Mercantile exceed 80% of the fair market value of the Company's fixed assets,
plus the Company's and guarantors' eligible accounts receivable (as defined).

maintenance of its radiology and imaging equipment. Total fees paid under this
arrangement approximate $950,000 per year, and are subject to adjustment to
reflect changes in the equipment and clinical needs of the Company.
 
7. EMPLOYEE BENEFIT PLAN:
 
     The Company sponsors a 401(k) plan for employees of the Company and its
five corporate members who have completed one year of service and are at least
age 21. The plan does not provide for employer matching contributions, but does
allow discretionary employer contributions. The Company's contribution in 1995

     The Company performs radiology and imaging healthcare services under
managed care contracts entered into and administered by AMI (see Note 3), and
remits a management fee to AMI. Such management fees were not significant in
1995 and 1996. In addition, the Company pays certain expenses on behalf of AMI
and is periodically reimbursed. There are no significant amounts due from or to
AMI at December 31, 1995 and 1996.
 
     The Company leases seven of its office facilities from entities in which
certain of the Company's members have ownership interests. Rent expense relating
to such facilities was approximately $800,000 in 1995 and $796,000 in 1996.
There were no such arrangements during 1994.
 
9. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. The carrying amounts of accounts receivable, accounts payable and
accrued expenses approximate fair value due to the short maturity of these
instruments. The carrying amount of the Company's long-term debt also
approximates fair value.
 
10. MEMBERSHIP REDEMPTION OPTION:
 
     Under the terms of the Company's operating agreement, at any time on or
after October 17, 1999, the Company has the option to redeem the membership
interests of all of the Class B members (which are the corporate members of the
Company) at a price equal to the then positive capital account balances of such
members, or, if such balances are zero or negative, for a price of $10.
Twenty-five percent of the redemption price is to be paid no later than six
months after the exercise of the option with the remainder generally being paid
in three annual installments, including interest.
 
11. CONTINGENCIES:
 
     The Company is a defendant in certain claims arising from alleged acts of
malpractice. Legal counsel for the Company is of the opinion that such claims
are adequately covered by malpractice insurance.
 
     The Company is a defendant in a lawsuit brought by two former employees of
a Class B member alleging employment discrimination. Total damages claimed are
$80 million. The case has been compelled to binding arbitration; however, no
Scheduling Order has been issued, and no substantive discovery has taken place.
In the opinion of management, the ultimate disposition of this case will not
have a material adverse effect on the Company's financial condition or results
of operations.

     During 1996, the Company became self-insured for employee health insurance
benefits. Stop-loss insurance coverage has been purchased which covers all
claims exceeding $35,000 per family with an aggregate maximum limit of 125% of
expected claims, as determined by the insurance company (approximately $684,000
in 1996).
 
12. SUBSEQUENT EVENTS:
 
     On August 13, 1996, the Company entered into a letter of intent with
American Physician Partners, Inc. (APPI) under which APPI will acquire certain
assets and liabilities of the Company in exchange for common stock and cash.
Completion of the transaction is subject to certain conditions, including the
execution of a forty-year service agreement, stockholder approval by both
parties and successful completion of an initial public offering by APPI. Under
the terms of the service agreement, APPI will provide practice management,
administration and other services to the physicians for a negotiated service
fee. All nonprofessional employees shall become employees of APPI. In addition,
APPI will assume responsibility for all maintenance, repairs, improvements,
leases and other general operating expenses.
 
     Effective January 1, 1997, Drs. Perilla, Sindler & Associates, P.A. (PSA)
contributed certain assets and liabilities to the Company in exchange for an
11.39% ownership interest. This transaction will be accounted for using the
purchase method.

To the Board of Directors and Shareholders of
Drs. Thomas, Wallop, Kim and Lewis, P.A.
(d/b/a Arundel Radiology):
 
     We have audited the accompanying balance sheet of Drs. Thomas, Wallop, Kim
and Lewis, P.A. as of December 31, 1994, and the related statements of income,
owners' equity, and cash flows for the year then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Drs. Thomas, Wallop, Kim and
Lewis, P.A. as of December 31, 1994, and the results of its operations and its
cash flows for the year then ended in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1994
 
1. BUSINESS, ORGANIZATION AND BASIS OF PRESENTATION:
 
     Drs. Thomas, Wallop, Kim and Lewis, P.A. (d/b/a Arundel Radiology, or
"Arundel") is a professional services corporation that is engaged in the
practice of medicine, specializing in radiology in Baltimore, Maryland. The
accompanying financial statements have been prepared on the accrual basis of
accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Accounts Receivable
 
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payors for medical services
provided by physicians. Such amounts are reduced by an allowance for contractual
adjustments and other uncollectible amounts. Contractual adjustments result from
the differences between the rates charged by the physicians for services
performed and the amounts allowed by the Medicare and Medicaid programs and
other public and private insurers.
 
  Property and Equipment
 
     Property and equipment are recorded at cost. Depreciation on furniture,
fixtures, and equipment is calculated using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are amortized using
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Income Taxes
 
     Arundel is a taxable corporation and historically has not incurred
significant tax liabilities for federal or state income taxes. Compensation to
physician owners has traditionally reduced taxable income to nominal levels.
This relationship would be expected to continue in the future. Because of this
practice, provisions for income taxes and deferred tax assets and liabilities
are not material and have not been reflected in the financial statements.
 
  Medical Service Revenues
 
     Medical service revenue are accounted for in the period in which the
services are provided. The revenue are reported at the estimated realizable
amounts from patients, third-party payors and others. Provisions for estimated
third-party payor adjustments are estimated and recorded in the period in which
the related services are provided. Any adjustment to the amounts is recorded in
the period in which the revised amount is determined. A significant portion of
Arundel's medical service revenue are related to Medicare and other governmental
programs. Medicare and other governmental programs reimburse physicians based on
fee schedules which are determined by the related governmental agency.
Additionally, Arundel participates in agreements with managed care organizations
to provide services at negotiated rates.
 
  Concentration of Credit Risk
 
     Arundel extends credit to patients covered by programs such as Medicare and
Medicaid and private insurers. Arundel manages credit risk with the various
public and private insurance providers, as appropriate. Allowances for bad debts
have been made for potential losses when appropriate.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
3. PROPERTY AND EQUIPMENT:
 
     Property and equipment consists of the following:

                         NOTES TO FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1994
 
1. BUSINESS, ORGANIZATION AND BASIS OF PRESENTATION:
 
     Diagnostic Imaging Associates, P.A. (DIAPA) is a professional services
corporation that is engaged in the practice of medicine, specializing in
radiology in Baltimore, Maryland. The accompanying financial statements have
been prepared on the accrual basis of accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Accounts Receivable
 
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payors for medical services
provided by physicians. Such amounts are reduced by an allowance for contractual
adjustments and other uncollectible amounts. Contractual adjustments result from
the differences between the rates charged by the physicians for services
performed and the amounts allowed by the Medicare and Medicaid programs and
other public and private insurers.
 
  Property and Equipment
 
     Property and equipment are recorded at cost. Depreciation on furniture,
fixtures, and equipment is calculated using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are amortized using
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Income Taxes
 
     DIAPA is a taxable corporation and historically has not incurred
significant tax liabilities for federal or state income taxes. Compensation to
physician owners has traditionally reduced taxable income to nominal levels.
This relationship would be expected to continue in the future. Because of this
practice, provisions for income taxes and deferred tax assets and liabilities
are not material and have not been reflected in the financial statements.
 
  Medical Service Revenues
 
     Medical service revenue are accounted for in the period in which the
services are provided. The revenue are reported at the estimated realizable
amounts from patients, third-party payors and others. Provisions for estimated
third-party payor adjustments are estimated and recorded in the period in which
the related services are provided. Any adjustment to the amounts is recorded in
the period in which the revised amount is determined. A significant portion of
DIAPA's medical service revenue are related to Medicare and other governmental
programs. Medicare and other governmental programs reimburse physicians based on
fee schedules which are determined by the related governmental agency.
Additionally, DIAPA participates in agreements with managed care organizations
to provide services at negotiated rates.
 
  Concentration of Credit Risk
 
     DIAPA extends credit to patients covered by programs such as Medicare and
Medicaid and private insurers. DIAPA manages credit risk with the various public
and private insurance providers, as appropriate. Allowances for bad debts have
been made for potential losses when appropriate.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

     DIAPA does not provide post-retirement or post-employment benefits to
employees.
 
8. DISCLOSURES ABOUT THE FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. The carrying amounts of accounts receivable, accounts payable,
accrued expenses, short-term notes, and capitalized lease approximate fair value
due to the short maturity of these instruments. The carrying amount of DIAPA's
long-term debt also approximates fair value.
 
9. INVESTMENT IN JOINT VENTURE:
 
     Effective July 1, 1994, DIAPA acquired a fifty percent interest in Greater
Baltimore Diagnostic Imaging Partnership (GBDIP), a general partnership, from
LaSalle Pavilion, Inc. ("LaSalle"), in settlement of amounts owed to DIAPA by
LaSalle. The investment in GBDIP is accounted for under the equity method.
 
     Summary information from the unaudited financial statements of GBDIP as of
and for the year ended June 30, 1994, is as follows:

                          INDEPENDENT AUDITORS' REPORT
 
To the Shareholders of
The Ide Group, P.C.:
 
     We have audited the accompanying combined balance sheets of The Ide Group,
P.C. (a New York professional corporation) and Ide Diagnostic Imaging Associates
(a New York general partnership) as of June 30, 1996, 1995 and 1994, and the
related combined statements of income, changes in stockholders' equity and
partners' capital, and cash flows for the three years then ended. These
financial statements are the responsibility of the Companies' management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free from
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of The Ide Group, P.C.
and Ide Diagnostic Imaging Associates as of June 30, 1996, 1995, and 1994, and
the results of their operations and their cash flows for the years then ended in
conformity with generally accepted accounting principles.

for the interim periods from July 1, 1995, to March 31, 1996, and from July 1,
1996, to March 31, 1997, have been included herein. The results of operations

3. LINES OF CREDIT:
 
     Ide has a line of credit facility with M&T Bank under which Ide may borrow
up to $1,300,000 at the prime rate (8.25% at June 30, 1996). There were no
borrowings outstanding under this line at June 30, 1996. The line of credit
agreement requires that there be no outstanding borrowings under the line for at
lease thirty consecutive days each year.
 
     Ide previously had an agreement with Chase Manhattan Bank, N.A. which
permitted Ide to borrow up to $600,000 through February 28, 1996. Borrowings
under the agreement were $200,000 and $600,000 at June 30, 1995 and 1994. The
note was repaid in full and terminated in February 1996.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Partnership had available a $200,000 line of credit. Amounts borrowed
bear interest at the prime plus  1/2%. There were no outstanding balances under
this line of credit at June 30, 1994, respectively. Amounts borrowed are
collateralized by accounts receivable.
 
4. LIFE INSURANCE LOANS PAYABLE:
 
     Ide's life insurance loans payable are secured by the cash surrender value
of the related policies. These policies bear interest at rates which range from
a fixed rate of five percent to rates which float with the prime rate. It is
Ide's intention to not repay these loans during the next year. Therefore, the
loans are reflected as a long-term liability in the accompanying balance sheets.
 
5. INCOME TAXES:
 
     Ide follows the provisions of Statement of Financial Accounting Standards
Number 109, "Accounting for Income Taxes."
 
     Deferred taxes are recognized for temporary differences between the basis
of assets and liabilities for financial statement and income tax purposes. The
differences result from the use of the cash basis of accounting for income tax
purposes and the use of the accrual basis of accounting for financial statement
purposes, and consist primarily of accounts receivable, accounts payable,
accrued liabilities and net operating loss carryforwards. It is Ide's intention
in future years to pay compensation to employees in amounts sufficient to reduce
taxable income to zero each year.
 
     For federal tax return purposes, Ide has approximately $422,474 of net
operating loss carryforwards as of June 30, 1996, which begin to expire in the
year 2006 through 2007.
 
     The results of the Partnerships' operations are reported in the individual
federal and state income tax returns of the partners. The Partnership files
informational returns and, therefore, no provision for income taxes is recorded.
 
6. REFUNDABLE BONDS:
 
     Refundable bonds consist of deposits required for each Ide physician by
Ide's medical malpractice mutual insurance carrier. The bonds are refundable
from the free and divisible surplus of the insurance company upon cessation of
medical practice of the Ide physician. The bonds earn interest at the rate of
six percent.
 
7. EMPLOYEE BENEFIT PLANS:
 
     Ide maintains a discretionary qualified defined contribution 401(k) and
profit sharing plan ("the Plan"), covering substantially all employees of Ide
and IDIA who have attained the age of 21 and who have met certain minimum
eligibility requirements. The plan is subject to provisions of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"). The plan also
provides that participants will be able to contribute up to 15% of their
compensation not to exceed $9,500. Ide contributes an amount equal to 25% of an
employee elective deferrals up to 4% of each employees compensation.
 
     In addition, Ide maintains a qualified discretionary supplemental profit
sharing plan which is subject to provisions of ERISA. The profit sharing expense
under these plans was $539,737, $518,107 and $588,227 for the years ended June
30, 1996, 1995 and 1994, respectively.

8. COMMITMENTS AND CONTINGENCIES:
 
  Deferred Compensation Agreements
 
     Each Ide shareholder physician's employment contract contains a deferred
compensation agreement. Under the terms of these agreements, these individuals
will receive payments at retirement or death for past services performed. At
June 30, 1996, 1995 and 1994 the vested amount of deferred compensation balances
total approximately $9,016,000, $7,329,000, and $6,970,000, respectively. These
balances will be paid out over time at indeterminable future dates and in
indeterminable future amounts. As such, the amount of liability that would be
recorded in the balance sheet is not reasonably estimable.
 
  Leases
 
     Ide occupies certain offices under lease agreements expiring at various
dates through December, 2000. The minimum rental commitment under all leases in
effect at June 30, 1996 is as follows:

     The Partnership leases office space under leases expiring through 1998. The
Partnership is fully reimbursed for its office space rental expense under the
terms of its agreement with MICA (see Note 12).
 
9. RELATED PARTY:
 
     Ide has an agreement with an affiliated company whereby the affiliate
performs billing and collection functions for services rendered by Ide. Ide pays
the affiliate a fee based on the amount of billings collected. Payments to this
affiliate were $1,547,143, $1,324,882 and $1,161,287 in fiscal 1996, 1995 and
1994, respectively.
 
10. CREDIT RISK CONCENTRATIONS:
 
     Ide and IDIA maintain bank account balances which, at times, exceeded the
federally insured limit during the years ended June 30, 1996, 1995 and 1994. The
Companies have not experienced losses related to these deposits and management
does not believe that the Companies are exposed to any significant credit risk
with respect to these accounts.
 
     At June 30, 1996, Ide has approximately $1,270,568 of accounts receivable
due from Health Maintenance Organizations ("HMO") which is subject to
retrospective adjustment. This amount represents withholdings by the HMOs to be
used against any operating losses incurred by the HMO. In fiscal 1996, Ide
received 80% of funds withheld under its contract with one HMO relating to
calendar 1995. Other than fiscal 1996, Ide has historically collected the full
amount of withheld funds each year.
 
     Substantially all of the Companies' revenue are derived from services
performed in the greater Rochester, New York metropolitan area.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Substantially all of the Companies' revenue are derived from providing
medical services to patients covered under contracts with Blue Cross/Blue Shield
of Greater Rochester or affiliates, Blue Choice, Preferred Care, Medicare, or
Medicaid. Changes in the reimbursement rates Ide receives under these contracts
could have a material effect on Ide's financial position and operations.
 
     Subsequent to June 30, 1996, Ide's management became aware of the intention
of the Rochester Community Individual Practice Association and the Rochester
Individual Practice Association, with whom Ide is a participating provider, to
adopt Resource-Based Relative Value Scale ("RBRVS") fee schedule methodologies.
These Individual Practice Associations contract with Blue Choice and Preferred
Care, respectively. Approximately 60% of Ide's revenue is derived from services
provided to patients of Blue Choice and Preferred Care. While the impact and
timing of the adoption of RBRVS methodologies are not yet known with certainty,
it is expected that this change may have a material detrimental effect on Ide's
future operations.
 
11. SUPPLEMENTARY CASH FLOW DISCLOSURES:
 
     Cash payments for income taxes and interest are as follows for the years
ended June 30:

12. EXCLUSIVE SUPPLY AGREEMENT:
 
     In August 1990, IDIA entered into a thirty-year agreement with MICA Imaging
and Medical Imaging Centers of America, Inc. ("MICA") in which IDIA agreed to
sell to MICA its magnetic resonance imaging ("MRI") equipment and not to compete
with MICA for the provision of MRI services in the City of Rochester ("City")
and within a twenty-five mile radius of the City. This covenant not to compete
also applies to all partners of IDIA for the duration of their participation as
a partner and for two years thereafter.
 
     Under the agreement, MICA granted IDIA the right of first refusal for the
thirty-year term of the agreement to provide professional radiology services at
facilities located in specific states in the Northeast except under certain
circumstances as outlined in the agreement.
 
     IDIA also grants to MICA, for the thirty-year term of the agreement, the
right of first refusal to provide MRI equipment, cryogens and/or maintenance at
any location in specific states in the Northeast where IDIA obtains the right to
provide MRI equipment, cryogens and/or maintenance or owns, leases or subleases
office space for the purposes of providing MRI services.
 
     IDIA and MICA also entered into an equipment lease covering MRI equipment
sold by IDIA to MICA and other MRI equipment operated in private offices located
on the campuses of certain Rochester area hospitals. These lease terms range
from five to thirty years. The rental payments are based upon the aggregate
number of MRI scans performed by IDIA using all leased MRI equipment.
 
     If certain events occur under this agreement, IDIA may be required to
purchase all fixed and mobile MRI equipment owned by MICA and leased to IDIA as
well as to assume leases for fixed MRI equipment leased by MICA and subleased to
IDIA by MICA.
 
     IDIA also may be required to pay MICA a pro-rated portion of the amount for
the exclusive supply contract.
 
     During fiscal 1996, the exclusive supply agreement was assigned by IDIA to
Ide with the consent of MICA.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Shareholders of
M&S X-Ray Practices:
 
     We have audited the accompanying combined balance sheets of M&S X-Ray
Practices (see Note 1) as of December 31, 1996 and 1995, and the related
combined statements of income, owners' equity, and cash flows for the years then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of M&S X-Ray Practices as of
December 31, 1996 and 1995, and the results of their operations and their cash
flows for the years then ended in conformity with generally accepted accounting
principles.

                           DECEMBER 31, 1995 AND 1996
 
1. BUSINESS, ORGANIZATION AND BASIS OF PRESENTATION:
 
     The accompanying combined financial statements combine the accounts of five
entities under common ownership: M&S X-ray Associates ("M&S"), a Texas
professional association, Madison Square Joint Venture ("Madison"), South Texas
MR, Inc. ("South Texas"), San Antonio MR Inc. ("San Antonio"), and Lexington MR
Ltd. ("Lexington") (collectively the "Company"), all of which are located in San
Antonio, Texas. M&S, a company specializing in radiological medicine, has and an
eight percent investment in Stone Oak Limited Partnership, a real estate limited
partnership. In addition, M&S holds forty-nine percent interest in Southeast
Baptist Imaging Center, a joint venture which owns and operates a diagnostic
imaging center. Madison is also engaged in the practice of radiological
medicine. South Texas holds a forty-nine percent interest in two joint ventures
which own and operate diagnostic imaging centers -- Northeast Baptist MRI Center
and Baptist Imaging Center. San Antonio holds a sixty percent interest in
Lexington, a company which owns and operates diagnostic imaging centers. An
additional nineteen percent of Lexington is owned by individual radiologists
included in the common ownership group. All intercompany transactions have been
eliminated.
 
     The accompanying combined financial statements have been prepared on the
accrual basis of accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with maturities of
three months or less when purchased to be cash equivalents.
 
  Accounts Receivable
 
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payors for medical services
provided by physicians. Such amounts are reduced by an allowance for contractual
adjustments and other uncollectible amounts.
 
  Property and Equipment
 
     Property and equipment are recorded at cost. Depreciation on furniture,
fixtures and equipment is computed using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are amortized on
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Investments in Joint Ventures
 
     Investments in joint ventures are accounted for using the equity method. In
addition, the Company holds an investment in a limited partnership which is
accounted for using the cost method.
 
  Other Assets
 
     Other assets are comprised of organization costs, loan origination costs
and goodwill. Loan origination costs are amortized on a straight-line basis over
the term of the loan. Organization costs are amortized on a straight-line basis
over a five-year period. Goodwill is amortized on a straight-line basis over 15
years.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Deferred Compensation
 
     Under the terms of the physician employment agreements, physicians who have
completed a minimum of five years of service are entitled to a payment equal to
two-thirds of their final compensation upon retirement or when they cease to be
employees of the Company. These payments are made in sixty equal monthly
payments beginning upon attainment of age 70 or the date when the physician
leaves the Company. The estimated present value of these liabilities is accrued
ratably during the five year service period.
 
  Medical Service Revenues
 
     Medical service revenue are accounted for in the period in which the
services are provided. The revenue are reported at the estimated realizable
amounts from patients, third party payors and others. Provisions for estimated
third party payor adjustments are estimated and recorded in the period the
related services are provided. Any adjustment to the amounts is recorded in the
period in which the revised amount is determined. A significant portion of the
Company's medical service revenue are related to Medicare and other governmental
programs. Medicare and other governmental programs reimburse physicians based on
fee schedules which are determined by the related governmental agency.
Additionally, the Company participates in agreements with managed care
organizations to provide services at negotiated rates.
 
  Costs of Affiliated Physician Services
 
     Costs of Affiliated Physician Services include physician compensation and
benefits paid or payable to owner and non-owner physicians during the period.
 
  Income Taxes
 
     As each of the consolidated entities is a non-taxable entity, there is no
provision for income taxes in the accompanying financial statements. The
individual owners include their respective share of Company profits and losses
in their tax returns.
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Basis of Presentation -- Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the

     The Company also collects the receivables of the joint ventures, and then
periodically remits the collections to them. In addition, the Company pays
certain expenses on behalf of the joint ventures, and is periodically reimbursed
by them. At December 31, 1996, there were no significant balances due from (to)

10. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. Accordingly, the carrying amounts of accounts receivable, accounts
payable and accrued expenses approximate fair value due to the short maturity of
these instruments. The carrying amount of the Company's long-term debt and
capital lease obligations also approximates fair value.
 
11. CONTINGENCIES:
 
     The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the
Company's financial position or results of operations.
 
12. SUBSEQUENT EVENTS:
 
     On September 24, 1996, the Company entered into a letter of intent with
American Physician Partners, Inc. (APPI) under which APPI will acquire certain
assets and liabilities of the Company in exchange for common stock and cash.
Completion of the transaction is subject to certain conditions, including the
execution of a forty-year service agreement, stockholder approval by both
parties and successful completion of an initial public offering by APPI. Under
the terms of the service agreement, APPI will provide practice management,
administration and other services to the physicians for a negotiated service
fee. All nonprofessional employees shall become employees of APPI. In addition,
APPI will assume responsibility for all maintenance, repairs, improvements,
lease and other general operating expenses.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Pacific Imaging Consultants:
 
     We have audited the accompanying combined balance sheets of Pacific Imaging
Consultants (see Note 1) as of December 31, 1995 and 1996, and the related
combined statements of income, owners' equity (deficit) and cash flows for the
years then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Pacific Imaging Consultants
as of December 31, 1995 and 1996, and the results of their operations and their
cash flows for the years then ended in conformity with generally accepted
accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                           DECEMBER 31, 1995 AND 1996
 
1. BUSINESS, ORGANIZATION AND BASIS OF PRESENTATION:
 
     The accompanying financial statements combine the accounts of three
entities under common ownership: Pacific Imaging Consultants, A Medical Group,
Inc. ("Pacific"), a California corporation formerly known as East Bay Medical
Imaging; Total Medical Imaging (TMI), a California S-corporation; and Lafayette
Medical Imaging Health Services (LMI), a California general partnership
(collectively the "Company"), all of which are located in the San Francisco Bay
area. The Company specializes in radiological medicine and the operation of
diagnostic imaging equipment. All intercompany transactions have been
eliminated.
 
     The accompanying financial statements have been prepared on the accrual
basis of accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Accounts Receivable
 
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payors for medical services
provided by physicians. Such amounts are reduced by an allowance for contractual
adjustments and other uncollectible amounts.
 
  Property and Equipment
 
     Property and equipment is recorded at cost. Depreciation on furniture,
fixtures and equipment is computed using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are amortized on
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Intangible Assets
 
     Intangible assets are comprised of organization costs and noncompete
agreements. Organization costs are being amortized on a straight-line basis over
a five-year period. Noncompete agreements are amortized on a straight-line basis
over the life of the agreements.
 
  Other Assets
 
     Other assets are comprised of equity investments in affiliated entities,
deposits and other receivables. Investments in affiliated entities are being
accounted for under the cost method and equity method as appropriate, based on
percentage of ownership and control of the entity. Such investments are not
material at December 31, 1996.
 
  Medical Service Revenues
 
     Medical service revenue are accounted for in the period in which the
services are provided. The revenue are reported at the estimated realizable
amounts from patients, third party payors and others. Provisions for estimated
third party payor adjustments are estimated and recorded in the period in which
the related services are provided. Any adjustment to the amounts is recorded in
the period in which the revised amount is determined. A significant portion of
the Company's medical service revenue are related to Medicare and other
governmental programs. Medicare and other governmental programs reimburse
physicians based on fee schedules which are determined by the related
governmental agency. Additionally, the Company participates in agreements with
managed care organizations to provide services at negotiated rates.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Costs of Affiliated Physician Services
 
     Costs of Affiliated Physician Services include physician compensation and
benefits paid or payable to owner and non-owner physicians during the period.
 
  Income Taxes
 
     Pacific accounts for income taxes under the liability method which states
that deferred income taxes are determined based on the estimated future tax
effects of differences between the financial reporting and income tax basis of
assets and liabilities given the provisions of enacted tax laws. Deferred income
tax provisions are based on the changes to the asset or liability from period to
period. TMI is an S-corporation and LMI is a general partnership, and
accordingly, there is no provision for income taxes related to these entities.
The individual owners include their respective share of profits and losses in
their tax returns.
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the combined
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Basis of Presentation -- Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim periods from January 1, 1996, to March 31, 1996, and from
January 1, 1997, to March 31, 1997, have been included herein. The results of

7. EMPLOYEE BENEFIT PLAN:
 
     The Company has a defined benefit pension plan covering all physician
employees and shareholders. The benefits are based on the final pay of each
physician, with minimum flat dollar limits. The Company's funding policy is to
contribute annually the maximum amount that can be deducted for federal income
tax purposes. Contributions are intended to provide not only for benefits
attributed service to date but also for those expected to be earned in the
future.
 
     Effective May 31, 1996, the Company curtailed the benefits under the plan
through Board of Director resolution to terminate the Plan. Plan benefits were
effectively frozen at this date and physicians will earn no additional defined
benefits for future services. All unrecognized prior service cost and
unrecognized net obligation from the initial application of SFAS 87 have been
reduced to zero as of the effective date of the curtailment, resulting in a gain
from curtailment of approximately $1.9 million. The plan of settlement has not
been determined and subsequent gain or loss may be recorded upon settlement.
 
     The following table sets forth the plan's funded status and amounts
recognized in the Company's balance sheet at December 31,

8. RELATED-PARTY TRANSACTIONS:
 
     The Company has a non-interest bearing note receivable from an employee.
Amounts outstanding at December 31, 1995 and 1996 were $85,000 and $94,836,
respectively. The note has no stated maturity date.
 
     The Company has a note receivable from a physician which bears interest at
8.5% and matures in August, 1995. Amounts outstanding at December 31, 1995 and
1996 were $38,936 and $36,173, respectively.
 
     At December 31, 1995, the Company had a $25,000 note receivable from a
physician. This note was paid in full in 1996.
 
     At December 31, 1996, the Company had a $10,000 note receivable from a
physician which bears interest at 8.25% and matures in 1997. In addition, in
1996, the Company made non-interest bearing advances totaling $70,287 to certain
physicians. These advances are to be repaid in 1997.
 
     The Company has an ownership interest in a real estate partnership. Rent
paid to this partnership was $49,752 in 1995 and 1996.
 
9. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. Accordingly, the carrying amounts of accounts receivable, accounts
payable and accrued expenses approximate fair value due to the short maturity of
these instruments. The carrying amount of the Company's long-term debt also
approximates fair value.
 
10. CONTINGENCIES:
 
     The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the
Company's financial position or results of operation.
 
11. SUBSEQUENT EVENTS:
 
     On February 26, 1997, the Company entered into a letter of intent with
American Physician Partners, Inc. (APPI) under which APPI will acquire certain
assets and liabilities of the Company in exchange for common stock and cash.
Completion of the transaction is subject to certain conditions, including the
execution of a forty-year service agreement, stockholder approval by both
parties and successful completion of an initial public offering by APPI. Under
the terms of the service agreement, APPI will provide practice management,
administration and other services to the physicians for a negotiated service
fee. All nonprofessional employees shall become employees of APPI. In addition,
APPI will assume responsibility for all maintenance, repairs, improvements,
lease and other general operating expenses.
 
     Effective January 1, 1997, the Company and Valley Radiology Group, a group
of radiologists in San Jose, California, formed a management services
organization to manage their operations.

     Property and equipment are recorded at cost. Depreciation on furniture,
fixtures and equipment is computed using straight-line methods over the
estimated useful lives of the assets. Leasehold improvements are amortized on
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Investments in Affiliated Entities
 
     The Company has investments in two partnerships, Magnetic Resonance Imaging
Center of Kansas ("MRI") and Medical Building West Associates, LP ("MBW") which
are accounted for using the equity method and the cost method, respectively (see
Note 3).
 
  Other Noncurrent Assets
 
     Other noncurrent assets consist of deposits with insurance companies and a
note receivable.
 
  Medical Service Revenues
 
     Medical service revenue are accounted for in the period in which the
services are provided. Revenues are reported at the estimated realizable amounts
from patients, third party payors and others. Provisions for estimated third
party payor adjustments are estimated and recorded in the period the related
services are provided. Any adjustment to the amounts is recorded in the period
in which the revised amount is determined. A significant portion of the
Company's medical service revenue are related to Medicare and other governmental
programs. Medicare and other governmental programs reimburse physicians based on
fee schedules which are determined by the related governmental agency.
Additionally, the Company participates in agreements with managed care
organizations to provide services at negotiated rates.

  Income Taxes
 
     The Company accounts for income taxes under the liability method which
states that deferred income taxes are to be determined based on the estimated
future tax effects of differences between the financial reporting and income tax
bases of assets and liabilities given the provisions of enacted tax laws.
Deferred income tax provisions are based on the changes to the asset or
liability from period to period.
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Basis of Presentation - Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim periods from January 1, 1996, to March 31, 1996, and from
January 1, 1997, to March 31, 1997, have been included herein. The results of
operations for the interim periods are not necessarily indicative of the results
for the full year.

9. EMPLOYEE BENEFIT PLAN:
 
     The Company sponsors a defined contribution pension plan for employees of
the Company who have completed one year of service, with a minimum of 1,000

11. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. Accordingly, the carrying amounts of accounts receivable, accounts
payable, accrued expenses, short-term borrowings and long-term debt approximate
fair value due to the short maturity of these instruments.
 
12. CONTINGENCIES:
 
  Litigation
 
     The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the
Company's financial position or results of operations.
 
  Insurance
 
     The Company is self-insured for employee health benefits. Stop-loss
insurance coverage has been purchased to cover claims exceeding certain
retention limits. At December 31, 1996, the Company's maximum exposure for
health insurance claims was $20,000 per family with an aggregate maximum limit
of 125% of expected claims, as determined by the insurance company
(approximately $379,000 in 1996.) An estimate of the amount due and payable on
existing claims for which the Company is liable is included in accrued expenses.
 
13. SUBSEQUENT EVENTS:
 
     On January 20, 1997, the Company entered into a letter of intent with
American Physician Partners, Inc. (APPI) under which APPI will acquire certain
assets and liabilities of the Company in exchange for common stock and cash.
Completion of the transaction is subject to certain conditions, including the
execution of a forty-year service agreement, stockholder approval by both
parties and successful completion of an initial public offering by APPI. Under
the terms of the service agreement, APPI will provide practice management,
administration and other services to the physicians for a negotiated service
fee. All nonprofessional employees shall become employees of APPI. In addition,
APPI will assume responsibility for all maintenance, repairs, improvements,
lease and other general operating expenses.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Rockland Radiological Group:
 
     We have audited the accompanying combined balance sheets of Rockland
Radiological Group (Note 1) as of September 30, 1995 and 1996, and the related
combined statements of income, owners' equity (deficit), and cash flows for each
of the three years in the period ended September 30, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Rockland Radiological Group
as of September 30, 1995 and 1996, and the results of their operations and their
cash flows for each of the three years in the period ended September 30, 1996,
in conformity with generally accepted accounting principles.

(collectively the "Company"), all of which are located in the states of New York
and New Jersey and specialize in the practice of radiological medicine. All
intercompany items and transactions have been eliminated.
 
     The accompanying financial statements have been prepared on the accrual
basis of accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Cash and cash equivalents
 
     The Company considers all highly liquid investments with maturities of
three months or less when purchased to be cash equivalents.
 
  Accounts Receivable
 
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payors for medical services
provided by physicians. Such amounts are reduced by an allowance for contractual
adjustments and other uncollectible amounts.
 
  Property and Equipment
 
     Property and equipment is recorded at cost. Depreciation on furniture,
fixtures and equipment is computed using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are amortized on
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Deferred Compensation
 
     Under the terms of the physician employment agreements, physicians who have
completed a minimum of eight years of service are entitled to a payment of up to
one hundred percent of their final compensation upon retirement or when they
cease to be employees of the Company. The percentage of salary received by the
physician varies based upon the number of years of service. These payments are
made in 36 equal monthly payments beginning upon attainment of age 70 or the
date when the physician leaves the Company. The estimated present value of these
obligations is being accrued ratably during the eight year service period.
 
  Medical Service Revenue
 
     Medical service revenues are accounted for in the period in which the
services are provided. The revenues are reported at the estimated realizable
amounts from patients, third party payors and others. Provisions for estimated
third party payor adjustments are estimated and recorded in the period the
related services are provided. Any adjustment to the amounts is recorded in the
period in which the revised amount is determined. A significant portion of the
Company's medical service revenues are related to Medicare and other
governmental programs. Medicare and other governmental programs reimburse
physicians based on fee

schedules which are determined by the related governmental agency. Additionally,
the Company participates in agreements with managed care organizations to
provide services at negotiated rates.
 
  Costs of Affiliated Physician Services
 
     Costs of Affiliated Physician Services include physician compensation and
benefits paid or payable to owner and non-owner physicians during the period.
 
  Income Taxes
 
     MRI and RRG account for income taxes under the liability method which
states that deferred income taxes are to be determined based on the estimated
future tax effects of differences between the financial reporting and income tax
basis of assets and liabilities given the provisions of enacted tax laws.
Deferred income tax provisions are based on the changes to the asset or
liability from period to period. The remaining companies included in the
accompanying combined financial statements are S corporations, and accordingly,
there is no provision for income taxes related to these entities. The individual
owners include their respective share of Company profits and losses in their tax
returns.
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the combined
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
  Basis of Presentation -- Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim periods from October 1, 1995, to March 31, 1996, and from
October 1, 1996, to March 31, 1997, have been included herein. The results of
operations for the interim periods are not necessarily indicative of the results
for the full year.

8. EMPLOYEE BENEFIT PLAN:
 
     The Company sponsors a profit sharing and 401(k) plan for employees of the

contributions of 100% of employee contributions, up to 3% of the employee's
salary. The Company's contributions for 1994, 1995, and 1996 were $253,656,

10. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. The carrying amounts of accounts receivable, accounts payable and

instruments. The carrying amount of the Company's long-term debt and capital
leases also approximates fair value.
 
11. CONTINGENCIES:
 
     The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the

     On November 15, 1996, the Company entered into a letter of intent with
American Physician Partners, Inc. (APPI) under which APPI will acquire certain
assets and liabilities of the Company in exchange for common stock and cash.
Completion of the transaction is subject to certain conditions, including the
execution of a forty-year service agreement, stockholder approval by both
parties and successful completion of an initial public offering by APPI. Under
the terms of the service agreement, APPI will provide practice management,
administration and other services to the physicians for a negotiated service
fee. All nonprofessional employees shall become employees of APPI. In addition,
APPI will assume responsibility for all maintenance, repairs, improvements,
lease and other general operating expenses.

assets of Kingston Diagnostic Radiology, P.C. for $2,000,000 in cash and certain
assumed liabilities of approximately $1,850,000. Completion of the transaction
is subject to execution of a five-year service contract.
 
     On March 11, 1997, Wallkill Radiology Associates, P.C. ("Wallkill")
contributed all of its assets to the Company. In exchange, the sole stockholder
of Wallkill was made an equal partner of the Company. At December 31, 1996,
Wallkill had total assets of approximately $480,000. For the year ended December

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Valley Radiology Group:
 
     We have audited the accompanying combined balance sheets of Valley
Radiology Group (Note 1) as of December 31, 1995 and 1996, and the related
combined statements of income, owners' equity, and cash flows for the years then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Valley Radiology Group as of
December 31, 1995 and 1996, and the results of their operations and their cash
flows for the years then ended in conformity with generally accepted accounting
principles.

three months or less when purchased to be cash equivalents.
 
  Accounts Receivable
 
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payors for medical services
provided by physicians. Such amounts are reduced by an allowance for contractual
adjustments and other uncollectible amounts.
 
  Property and Equipment
 
     Property and equipment are recorded at cost. Depreciation on furniture,
fixtures and equipment is computed using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are amortized on
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Investments in Affiliated Entities
 
     Investments in affiliated entities are accounted for using the equity
method.
 
  Other Assets
 
     Other assets are comprised of organization costs, noncompete agreements and
security deposits. Organization costs are being amortized on a straight-line
basis over a five-year period. Noncompete agreements are amortized on a
straight-line basis over the life of the agreements.
 
  Medical Service Revenues
 
     Medical service revenues are accounted for in the period in which the
services are provided. The revenues are reported at the estimated realizable
amounts from patients, third party payors and others. Provisions for estimated
third party payor adjustments are estimated and recorded in the period in which
the related services are provided. Any adjustment to the amounts is recorded in
the period in which the revised amount is determined. A significant portion of
the Company's medical service revenues are related to Medicare and other
governmental programs. Medicare and other governmental programs reimburse
physicians based on fee schedules which are determined by the related
governmental agency. Additionally, the Company participates in agreements with
managed care organizations to provide services at negotiated rates.

  Costs of Affiliated Physician Services
 
     Costs of Affiliated Physician Services include physician compensation and
benefits paid or payable to owner and non-owner physicians during the period.
 
  Income Taxes
 
     Valley accounts for income taxes under the liability method which states
that deferred income taxes are determined based on the estimated future tax
effects of differences between the financial reporting and income tax basis of
assets and liabilities given the provisions of enacted tax laws. Deferred income
tax provisions are based on the changes to the asset or liability from period to
period. LXL and LXLB are partnerships, and accordingly, there is no provision
for income taxes related to these entities. The individual owners include their
respective share of profits and losses in their tax returns.
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the combined
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
  Basis of Presentation - Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim periods from January 1, 1996, to March 31, 1996, and from
January 1, 1997, to March 31, 1997, have been included herein. The results of
operations for the interim periods are not necessarily indicative of the results
for the full year.

third party, due July 18, 1999 with monthly interest only payments until that
date. The note bears interest of 8.0%.
 
4. INVESTMENTS IN AFFILIATED ENTITIES:

11. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. The carrying amounts of accounts receivable, accounts payable and
accrued expenses approximate fair value due to the short maturity of these
instruments. The carrying amount of the Company's long-term debt also
approximates fair value.
 
12. CONTINGENCIES:
 
     The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the
Company's financial position or results of operations.
 
13. SUBSEQUENT EVENTS:
 
     On March 6, 1997, the Company entered into a letter of intent with American
Physician Partners, Inc. (APPI) under which APPI will acquire certain assets and
liabilities of the Company in exchange for common stock and cash. Completion of
the transaction is subject to certain conditions, including the execution of a
forty-year service agreement, stockholder approval by both parties and
successful completion of an initial public offering by APPI. Under the terms of

Current Balance Sheet.

        Section 3.12 Litigation and Claims. There are no claims, lawsuits,
actions, arbitrations, administrative or other proceedings, governmental
investigations or inquiries pending or, to the knowledge of the Company,
threatened against, or affecting the Company, any Company Subsidiary, any

individual affiliated with the Company affecting or that would reasonably be
likely to affect the Company Common Stock or the operations, business condition,
(financial or otherwise), or results of operations of the Company which (i) if
successful, may, individually or in the aggregate, have a Material Adverse
Effect on the Company or (ii) could adversely affect the ability of the Company
or any Company Subsidiary to effect the transactions contemplated hereby, and to
the knowledge of the Company there is no basis for any such action or any state
of facts or occurrence of any event which would reasonably be likely to give
rise to the foregoing. There are no unsatisfied judgments against the Company or
any Company Subsidiary or any licensed professional or other individual
affiliated with the Company or any Company Subsidiary relating to services
provided on behalf of the Company or any Company Subsidiary or any consent
decrees to which any of the foregoing is subject. Each of the matters, if any,

Company or any Company Subsidiary as in effect on the date hereof.

        Section 3.13 No Violation of Law. Neither the Company nor any Company

federal law, ordinance, regulation, order, injunction or decree, or any other
requirement of any governmental body, agency, authority or court binding on it,
or relating to its properties, assets or business or its advertising, sales or

the Company.

        Section 3.14 Lease Agreements. The Disclosure Schedules contain a true,
accurate and complete list of all the lease agreements and license agreements to
which the Company or any Company Subsidiary is a party and pursuant to which the
Company or any Company Subsidiary leases (whether as lessor or lessee) or
licenses (whether as licensor or licensee) any real or personal property related
to the operation of its business and which requires payments in excess of
$12,000 per year (the "Lease Agreements"). The Company has delivered to APP true
and complete copies of all of the Lease Agreements. Each Lease Agreement is
valid, effective and in full force in accordance with its terms, and there is
not under any such lease (i) any existing or claimed material default by the
Company or any Company Subsidiary (as applicable) or event of material default
or event which with notice or lapse of time, or both, would constitute a
material default by the Company or any Company Subsidiary (as applicable) and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Company, or, (ii) to the knowledge of the Company, any existing
material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party. To the knowledge of the
Company, there is no pending or threatened reassessment of any property covered

consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver to
APP or APP Sub in writing such consents as are necessary to effect a valid and
binding transfer or assignment of the Company's or any Company Subsidiary's
rights thereunder. The Company has a good, clear, valid and enforceable
leasehold interest under each of the Lease Agreements. The Lease Agreements
comply with the exceptions to ownership interests and compensation arrangements
set out in 42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952, and any similar
applicable state law safe harbor or other exemption provisions.

               (b) The Company and any Company Subsidiary (i) has good title to
all of its properties and assets (real, personal and mixed, tangible and
intangible) and any rights or interests therein which it purports to own
including, without limitation, all the property and assets reflected in the
Company Current Financial Statements; and (ii) owns such rights, interests,
assets and property free and clear of all Encumbrances, title defects or
objections (except for taxes not yet due and payable). The personal property
presently used in connection with the operation of the business of the Company
and the Company Subsidiaries constitutes the necessary personal property assets
to continue operation of the Company and any Company Subsidiary.

        Section 3.16 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, the Company does not have any
direct or indirect indebtedness for borrowed money, including indebtedness by
way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

        Section 3.17 Contracts and Commitments.

               (a) The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health
maintenance organization, other managed care organization or other third-party
provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of
obligations of third parties requiring the Company to make, or setting forth
conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000 in
any fiscal year or $25,000 in the aggregate and that are not cancelable by
providing notice of sixty (60) days or less. All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is with
unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP or APP Sub of the
assets and properties to be acquired by APP or APP Sub from the Company, or
which could inhibit or prevent the Company from transferring to or vesting in
APP or APP Sub good and sufficient title to the assets and properties to be
acquired by APP or APP Sub and the Surviving Corporation except where the
failure to transfer would not have a Material Adverse Effect on APP or APP Sub.
In every instance where consent is necessary, the Company shall, on or before
the Closing Date, use reasonable good faith efforts to obtain and deliver to APP
or APP Sub in writing, effective as of the Closing Date, such consents as are
necessary to enable the Surviving Corporation to enjoy all of the rights now
enjoyed by the Company under such contracts. Any and all such consents


                                       12
<PAGE>   321
shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. Notwithstanding the foregoing, the Company shall not transfer to APP
or APP Sub any contracts or agreements relating to the provision of professional
medical services or other such agreements and contracts that APP consents to in
writing to be transferred to NewCo in the Spin-off Transaction. No contract with
a health care provider or Payor has been materially amended or terminated within
the last twelve (12) months.

               (b) The Company (i) has not received notice of any plan or
intention of any other party to exercise any right to cancel or terminate any
contract, agreement or instrument required to be disclosed pursuant to Section
3.17(a), and to the knowledge of the Company there are no fact(s) that would
justify the exercise of such a right; and (ii) does not currently contemplate,
or have reason to believe any other Person currently contemplates, any amendment
or change to any such contract, agreement or instrument.

        Section 3.18 Employee Matters. The Company is not currently a party to
any employment contract (except for oral employment agreements which are
terminable at will), consulting or collective bargaining contracts, deferred
compensation, pension plan (as defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974, as amended, and all rules and
regulations from time to time promulgated thereunder ("ERISA")), profit sharing,
bonus, stock option, stock purchase or other nonqualified benefit or
compensation commitments, benefit plans, arrangements or plans (whether written
or oral), including all welfare plans (as defined in Section 3(1) of ERISA) of
or pertaining to the Company and any of its present or former employees, or any
predecessors in interest. As of April 30, 1997, the Company employed a
collective total of [ ] part-time and [ ] full-time employees and [ ] per diem

generally to all other employees) and bonuses in 1997 in excess of $50,000. The
Company is not delinquent in payment to any of its employees or Physician
Employees for wages, salaries, bonuses or other direct compensation for any
services performed for it to the date hereof or amounts required to be

of employment.

               (b) To the knowledge of the Company, there is no unfair labor
practice, charge or complaint or any other employment-related matter against or
involving the Company pending or threatened before the National Labor Relations
Board or any federal, state or local agency, authority or court;

Employment Opportunity Commission or any federal, state or local agency or court
against the Company. There have been no governmental audits of the equal
employment opportunity practices of the Company and, to the knowledge of the
Company, no basis for any such audit exists which, if conducted would result in
a Material Adverse Effect on the Company;

instruments, insurance contracts or policies related to an Employee Benefit

Subject to the requirements of ERISA, each of the Employee Benefit Plans can be
terminated or amended at will by the Company without any further liability or
obligation on the part of such entity to make further contributions or payments
in connection therewith following such termination. No unwritten amendment
exists with respect to any Employee Benefit Plan.

               (b) Administration. Each Employee Benefit Plan has been
administered and maintained in compliance with all applicable laws, rules and
regulations, except where the failure to be in compliance would not,
individually or in the aggregate, result in a Material Adverse Effect.

any Employee Benefit Plan is currently the subject of an audit, investigation,
enforcement action or other similar proceeding conducted by any state or federal
agency or authority.

               (d) Prohibited Transactions. No prohibited transactions (within
the meaning of Section 4975 of the Code or Section 406 of ERISA) have occurred

likely to result, directly or indirectly, (including through any obligation of
indemnification or contribution), in any taxes, penalties or other liability to
APP or any of its Affiliates.

               (e) Claims and Litigation. No pending or, to the Company's

Plans intended to be qualified within the meaning of Section 401(a) or 501(c)(9)
of the Code and/or tax-exempt within the meaning of Section 501(a) of the Code
and, to the best knowledge of the Company and each Stockholder, has been

respect to any Employee Benefit Plan or any plan sponsored by any member of a
controlled group (within the meaning of Section 412(n)(6)(B) of the Code) in
which the Company is a member (a "Controlled Group"). With respect to each
Employee Benefit Plan subject to Title IV of ERISA, the assets of each such plan
are at least equal in value to the present value of accrued benefits determined
on an ongoing basis as of the date hereof. With respect to each Employee Benefit
Plan described in Section 501(c)(9) of the Code, the assets of each such plan
are at least equal in value to the present value of accrued benefits, based upon
the most recent actuarial valuation as of a date no more than ninety (90) days
prior to the date hereof. The Disclosure Schedules contain a complete and
accurate statement of all actuarial assumptions applied to determine the present
value of accrued benefits under all Employee Benefit Plans subject to actuarial
assumptions.

               (h) Excise Taxes. Neither the Company nor any member of a
Controlled Group has any liability to pay excise taxes with respect to any
Employee Benefit Plan under applicable provisions of the Code or ERISA.

               (i) Multiemployer Plans. Neither the Company nor any member of a
Controlled Group is or ever has been obligated to contribute to a multiemployer
plan within the meaning of Section 3(37) of ERISA or any other Employee Benefit
Plan which has been subject to Title IV of ERISA or Section 412 of the Code.

would result in the imposition of liability against APP, APP Sub or any of its
Affiliates by the Pension Benefit Guaranty Corporation ("PBGC") as a result of
any act or omission by the Company or any member of a Controlled Group. No
reportable event (within the meaning of Section 4043 of ERISA) for which the
notice requirement has not been waived has occurred with respect to any Employee
Benefit Plan subject to the requirements of Title IV of ERISA.

               (k) Retirees. The Company has no obligation or commitment to
provide medical, dental or life insurance benefits to or on behalf of any of its
employees who may retire or any of its former employees who have retired except
as may be required pursuant to the continuation of coverage provisions of
Section 4980B of the Code and the applicable provisions of ERISA.

               (l) Other Compensation Arrangements. Neither the Company nor, to
the Company's knowledge, any Stockholder or Physician Employee is a party to any
compensation or debt arrangement with any Person relating to the provision of
health care related services other than arrangements with the Company.

        Section 3.21 Environmental Matters.

               (a) Neither the Company nor any Company Subsidiary has, within
the five (5) years preceding the date hereof, through the Effective Time,
received from any federal, state or local governmental body, agency, authority
or entity, or any other Person, any written notice, demand, citation, summons,
complaint or order or any notice of any penalty, lien or assessment, and to the
knowledge of the Company no investigation or review is pending by any

               (b) Neither the Company nor any Company Subsidiary has used,
transported, disposed of or arranged for the disposal of (as those terms are
defined in and construed under the Comprehensive Environmental Response,
Compensation and Liability Act) any Hazardous Substance (as defined herein) that
would be reasonably likely to give rise to any Environmental Liabilities (as
defined in subsection (e) below) for the Company under any applicable
Environmental Law that had, or would


                                       15
<PAGE>   324
reasonably be likely to have, a Material Adverse Effect on the Company. Neither
the Company nor any Company Subsidiary has engaged in any activity or failed to

respect thereto (calculated consistent with past practice), of items of a
quality and a quantity usable and saleable in the ordinary course of the
Company's business and conform to generally accepted standards in the industry
of which the Company is a part. The value of the inventories reflected on the
Company Current Balance Sheet contained in the Company Financial Statements are

Adverse Effect on the Company, and there is no action pending or to the
Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program, and

similar action.

               (b) The Company is not required, or for the 72-month period prior

give notice to the nonconsenting Stockholders of the action taken by the
consenting Stockholders as may be required by applicable law; provided, however,

covenants and agrees that it will take whatever steps are necessary to pay for
or fund completely any accrued benefits, where applicable, or vested accrued
benefits for which the Company or any entity might have any liability whatsoever
arising from any tax-qualified plan as required under applicable law. The
Company acknowledges that the purpose and intent of this covenant is to assure
that APP Sub shall have no liability whatsoever at any time after the Closing
Date with respect to any such tax-qualified plan, unless such plan is merged
with a plan sponsored by APP or APP Sub.

        Section 7.11 Accounting and Tax Matters. The Company will not change in
any material respect the accounting methods or practices followed by the Company
(including any material change in any assumption underlying, or any method of
calculating, any bad debt, contingency or other reserve), except as may be
required by generally accepted accounting principles. The Company will not make

with past practice, change any material tax election already made, adopt any tax
accounting method except in the ordinary course of business consistent with past
practice, change any tax accounting method, enter into any closing agreement,

Plans, all contracts and agreements and other assets listed on the Disclosure
Schedules (to be delivered by the Company prior to Closing, which schedule will
be subject to the approval of APP, which approval shall not be unreasonably
withheld) which by law either cannot be acquired or cannot be used by APP
because they relate to the practice of medicine or radiology, and shall
contribute to NewCo such other consideration and assets of the Company as may be
required under applicable law, in exchange for the issuance by NewCo of shares
of NewCo Common Stock, such shares being all of the issued and outstanding
shares of NewCo Common Stock. The Company shall then distribute the shares of
NewCo Common Stock to the Stockholders in proportion to their respective
ownership interest in the Company.

Qualified Plan shall be conditioned on a favorable determination letter from the

other appropriate Forms) to be filed by APP in connection with its Initial

APP Sub, will, at the time the Registration Statements and each amendment and
supplement thereto, if any, becomes effective under the Securities Act, none of
them contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. The Company shall be entitled to review the Registration Statements
and each of the amendments thereto, if any, prior to the time each becomes
effective under the Securities Act. The Company shall have no responsibility for
information contained in the Registration Statements except for information
provided by the Company specifically for inclusion therein. The Company's review
of the Registration Statements shall not diminish or otherwise affect the
representations, covenants and warranties of APP and APP Sub contained in this
Agreement.

Closing to supplement or amend promptly the Disclosure Schedules with respect to
any matter that would have been or would be required to be set forth or
described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Schedule that constitutes or reflects a
Material Adverse Effect on the Company may be made unless APP consents to such
amendment or supplement, and no amendment or supplement to a Disclosure Schedule
that constitutes or reflects a Material Adverse Effect on APP may be made unless
the Company consents to such amendment or supplement. For purposes of this
Agreement, including without limitation for purposes of determining whether the
conditions set forth in Sections 10.1 and 11.1 have been fulfilled, the
Disclosure Schedules hereto shall be deemed to be the Disclosure Schedules as
amended or supplemented pursuant to this Section 9.2. In the event that the
Company seeks to amend or supplement a Disclosure Schedule pursuant to this
Section 9.2 and APP does not consent to such amendment or supplement, or APP
seeks to amend


                                       32

Company does not consent, this Agreement shall be deemed terminated by mutual
consent as set forth in Section 15.1(a) hereof.

knowingly, either before or after the Merger, take any action that would prevent

351 of the Code.

        Section 9.4 Public Announcements. The parties hereto will consult with
each other before issuing any press release or making any public statement with

make any such public statement prior to such consultation, although the
foregoing shall not apply to any disclosure by APP in any filing with the DOJ,
FTC or SEC.

        Section 9.5 Expenses. Each party to this Agreement shall be solely
responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by the Company and NewCo in connection with the Merger
shall be paid by the Company in full immediately prior to the Closing and such
expenses shall be the sole responsibility of the Stockholders following the
Closing Date and not APP.

        Section 9.6 Patient Confidentiality. APP and APP Sub shall agree to keep
all records and information regarding the patients of the Company and NewCo
confidential in accordance with all applicable laws.

        Section 9.7 Registration Statements. APP shall prepare and file the

shall be maintained, and all Tax Returns and schedules thereto shall be filed in
a manner consistent with the Merger being treated as a Reorganization. These
obligations are excused as to a party required to maintain the books or file a
Tax Return if such party has provided to the other parties a written opinion of
competent tax counsel to the effect that there is not substantial authority,
within the meaning of Section 6662(d)(2)(B)(i) of the Code, to report the Merger
as a Reorganization and such opinion either is furnished prior to the Effective
Time or is based on facts or events not known at the Effective Time. Each party
shall provide to each other party such tax information, reports, returns, or
schedules as may be reasonably required to assist such party in accounting for
and reporting the Merger as a Reorganization.

        (c) The parties agree that no Stockholder shall be liable for any taxes
incurred by the Company and for which APP has successor liability therefor which
arise solely as a result of the Merger or the consummation of the transactions
contemplated hereby; provided that the foregoing shall not limit or otherwise be
deemed a waiver of any right of indemnification under Section 14.1 for a breach
of any representation, warranty or covenant of the Company or any Stockholder.

        Section 13.3 Current Public Information. APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

                                   ARTICLE XIV

                                    Remedies

        Section 14.1 Indemnification by the Company. Subject to the terms and
conditions of this Article XIV, the Company agrees to indemnify, defend and hold
APP and the Surviving Corporation and their respective directors, officers,
stockholders, employees, agents, attorneys, consultants and Affiliates harmless
from and against all losses, claims, obligations, demands, assessments,
penalties, liabilities, costs, damages, reasonable attorneys' fees and expenses
(including, without limitation, all costs of experts and all costs incidental to
or in connection with any appellate process) (collectively, "Damages") asserted
against or incurred by such individuals and/or entities arising out of or
resulting from:

               (a) a breach by the Company of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of the Company
contained in this Agreement or in any Disclosure Schedule or certificate
delivered thereunder;


                                       38
<PAGE>   347
               (b) any violation (or alleged violation) by the Company and/or
any of its past or present directors, officers, partners, stockholders,
employees (including, without limitation, any Physician Employee), agents,
attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons in
which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

               (c) any liability under the Securities Act, the Exchange Act or
any other federal or state "blue sky" or securities law or regulation, at common
law or otherwise, arising out of or based upon any (i) untrue statement of
material fact in any Registration Statement or any prospectus forming or part
thereof, or any amendment thereof or supplement thereto relating to the Company
(including any Company Subsidiary) or NewCo required to be stated therein or
(ii) failure to state information necessary to make the statements therein not
misleading, which untrue statement or failure to state information arises or
results solely from information provided in writing to APP or its counsel by the
Company or any Stockholder or their agents specifically for inclusion in any
such Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto.

        Section 14.2 Indemnification by APP and APP Sub. Subject to the terms
and conditions of this Article XIV, APP and APP Sub jointly and severally hereby
agree to indemnify, defend and hold the Stockholders, the Company and NewCo and
their respective directors, officers, stockholders, employees, agents,
attorneys, consultants and Affiliates harmless from and against all Damages
asserted against or incurred by such individuals and/or entities arising out of
or resulting from:

               (a) a breach by APP or APP Sub of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of APP or APP Sub
contained in this Agreement or in any schedule or certificate delivered
hereunder; and

               (b) any liability under the Securities Act, the Exchange Act or
any other federal or state "blue sky" or securities law or regulation, at common
law or otherwise, arising out of or based upon any untrue statements of material
fact in any Registration Statement or any prospectus forming a part thereof, or
any amendment thereof or supplement thereto, required to be stated therein or
failure to state information necessary to make the statements therein not
misleading (except for any liability based upon any actual or alleged untrue
statement of material fact or an omission to state a material fact relating to
NewCo, the Company or any Stockholder to the extent derived from any information
provided in writing by the Company or a Company Subsidiary or any of their
agents contained in the representations and warranties set forth in this
Agreement or any certificate, exhibit, schedule or instrument required to be
delivered under this Agreement.)

               Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
of any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

        Section 14.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

               (a) Any party claiming indemnification under the Agreement (an
"Indemnified Party") shall promptly (and, in the event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party for whom indemnification is sought (the "Indemnifying
Party) of any third-party claim or claims asserted against the Indemnified Party
("Third Party Claim") that could give rise to a right of indemnification under
this Agreement and (ii) transmit to the Indemnifying Party a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the


                                       39
<PAGE>   348
amount of Damages attributable to the Third Party Claim and the basis of the
Indemnified Party's request for indemnification under this Agreement. The
failure to promptly deliver a Claim Notice shall not relieve any Indemnifying
Party of its obligations to any Indemnified Party with respect to the related
Third Party Claim except to the extent that the resulting delay is materially
prejudicial to the defense of such claim. Within thirty (30) days after receipt
of any Claim Notice (the "Election Period"), the Indemnifying Party shall notify
the Indemnified Party (x) whether the Indemnifying Party disputes its potential
liability to the Indemnified Party under this Article XIV with respect to such
Third Party Claim and (y) whether the Indemnifying Party desires, at the sole
cost and expense of such Indemnifying Party, to defend the Indemnified Party
against such Third Party Claim.

               (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may employ separate counsel at the expense of the Indemnifying Party, and
upon written notification thereof, the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of the Indemnified Party;
provided further that the Indemnifying Party shall not, in connection with any
one such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

               (c) If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense


                                       40
<PAGE>   349
pursuant to this Section or of the Indemnifying Party's participation therein at
the Indemnified Party's request, and the Indemnified Party shall reimburse the
Indemnifying Party in full for all costs and expenses of such litigation. The
Indemnifying Party may participate in, but not control, any defense or
settlement controlled by the Indemnified Party pursuant to this Section 14.3(c),
and the Indemnifying Party shall bear its own costs and expenses with respect to
such participation; provided, however, that if the named parties to any such
action (including any impleaded parties) include both the Indemnifying Party and
the Indemnified Party, and the Indemnifying Party has been advised by counsel
that there may be one or more legal defenses available to it that are different
from or additional to those available to the Indemnified Party, then the
Indemnifying Party may employ separate counsel and upon written notification
thereof, the Indemnified Party shall not have the right to assume the defense of
such action on behalf of the Indemnifying Party.

               (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

               (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period for appeal of a final adjudication of the
Indemnifying Party's liability to the Indemnified Party under this Agreement.

               (f) The Indemnifying Party shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Party to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Party desired to accept such settlement.

               (g) Notwithstanding any provision herein to the contrary, the
obligation of an Indemnifying Party to provide indemnification to an Indemnified
Party for breach of any representation or warranty as provided in Sections
14.1(a) or 14.2(a) hereof shall not take effect unless and until the Damages
asserted against or incurred in the aggregate and on a collective basis by the
Indemnified Parties pursuant to either Section 14.1 or 14.2 (as applicable) as a
result of such a breach or breaches exceeds $100,000.

        Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'


                                       41
<PAGE>   350
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

        Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.

                                   Termination

        Section 15.1 Termination. This Agreement may be terminated and the
Merger and the Acquisitions may be abandoned:

               (a) at any time prior to the Effective Date by mutual agreement
of all parties;

               (b) at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and delivered
by the Company or any Stockholder pursuant to this Agreement is or becomes
untrue or breached in any material respect or if the Company or any Stockholder
fails to comply in any material respect with any material covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

               (c) at any time prior to the Effective Date by the Company if any
representation or warranty of APP or APP Sub contained in this Agreement or in
any certificate or other document executed and delivered by APP or APP Sub
pursuant to this Agreement is or becomes untrue in any material respect or if
APP fails to comply in any material respect with any covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

               (d) at any time prior to the Effective Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures, APP
deems termination to be advisable; or

               (e) by APP or the Company if the Merger shall not have been
consummated by September 30, 1997.

        Section 15.2 Effect of Termination. Except as set forth in Section 16.3,
in the event this Agreement is terminated pursuant to this Article XV, this

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

        Section 16.1 Non-Disclosure Covenant. The Company and NewCo recognize
and acknowledge that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP and the
Surviving Corporation that is valuable, special and a unique asset of such
entity's business. APP and APP Sub acknowledge that they had in the past,
currently have, and in the future may possibly have, access to certain
Confidential Information of the Company and NewCo that is valuable, special and
a unique asset of each such business. The Company, NewCo, APP, and APP Sub,
severally, agree that they will not disclose such Confidential Information to
any person, firm, corporation, association or other entity for any purpose or
reason whatsoever, except (a) to authorized representatives of APP, APP Sub,
Surviving Corporation, NewCo and the Company and (b) to counsel


                                       42
<PAGE>   351
and other advisers to APP, APP Sub, Surviving Corporation, NewCo and the Company
provided that such advisers (other than counsel) agree to the confidentiality
provisions of this Section 16.1, unless (i) such information becomes available
to or known by the public generally through no fault of the Company, NewCo, APP
or APP Sub, as the case may be, (ii) disclosure is required by law or the order
of any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii) the Company, NewCo, APP
or APP Sub, as the case may be, shall, if possible, give prior written notice
thereof to the Company, NewCo, APP or APP Sub and provide the Company, APP or
APP Sub with the opportunity to contest such disclosure, (iii) the disclosing
party reasonably believes that such disclosure is required in connection with
the defense of a lawsuit against the disclosing party, or (iv) the disclosing
party is the sole and exclusive owner of such Confidential Information as a
result of the Merger or otherwise. In the event of a breach or threatened breach
by the Company, on the one hand, and APP or APP Sub, on the other hand, of the
provisions of this Section, APP, APP Sub, the Surviving Corporation, NewCo and
the Company shall be entitled to an injunction restraining the other party, as
the case may be, from disclosing, in whole or in part, such Confidential
Information. Nothing herein shall be construed as prohibiting any of such
parties from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages.

        Section 16.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, APP Sub, the Surviving Corporation, NewCo and the
Company agree that, in the event of a breach by either of them of the foregoing
covenant, the covenant may be enforced against them by injunctions and
restraining orders.

        Section 16.3 Survival. The obligations of the parties under this Article
XVI shall survive the termination of this Agreement.

        Section 17.1 Amendment; Waivers. This Agreement may be amended, modified
or supplemented only by an instrument in writing executed by all the parties
hereto. Any waiver of any terms and conditions hereof must be in writing, and
signed by the parties hereto. The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

        Section 17.2 Assignment. Neither this Agreement nor any right created
hereby or in any agreement entered into in connection with the transactions
contemplated hereby shall be assignable by any party hereto, except by APP to a
wholly owned subsidiary of APP; provided that any such assignment shall not
relieve APP of its obligations hereunder.

        Section 17.3 Parties in Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. APP and APP Sub
acknowledge and agree that the rights and remedies of the Company under this
Agreement will be directly available to the Stockholders as third party
beneficiaries of the rights and remedies of the Company under this Agreement,
including, without limitation, the rights and remedies under Article 14 hereof
to indemnification from APP and APP Sub against Damages incurred by the
Stockholders resulting from a breach by APP or APP Sub of any representation,
warranty or covenant of APP or APP Sub contained herein. Except as provided in
the preceding sentence or as otherwise provided herein, neither this Agreement
nor any other agreement contemplated hereby shall be deemed to confer upon any
person not a party hereto or thereto any rights or remedies hereunder or
thereunder.

        Section 17.4 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior

of them, with respect to the subject matter hereof.

        Section 17.5 Severability. If any provision of this Agreement is held to
be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

        Section 17.6 Survival of Representations, Warranties and Covenants. The
representations, warranties and covenants contained herein shall survive the
Closing and all statements contained in any certificate, exhibit or other
instrument delivered by or on behalf of the Company, any Stockholder, APP or APP
Sub pursuant to this Agreement shall be deemed to have been representations and
warranties by the Company, such Stockholder, APP and APP Sub. Notwithstanding
any provision in this Agreement to the contrary, the representations and
warranties contained herein shall survive the Closing until the second
anniversary of the Closing Date except that (a) the representations and
warranties set forth in Section 3.21 with respect to environmental matters shall
survive for a period of ten (10) years, (b) the representations and warranties
set forth in Section 3.30 with respect to tax matters shall survive until such
time as the limitations period has run for all tax periods ended prior to the
Closing Date, (c) the representations and warranties contained in Section 3.27
and Section 3.33 with respect to healthcare matters shall survive for a period
of six (6) years and (d) solely for purposes of Section 14.1(c) and Section

such provisions actually incurs liability under the Securities Act, the Exchange
Act or any other federal or state securities law, the representations and
warranties set forth therein shall survive until the expiration of any
applicable limitations period.

        Section 17.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING

each share of Company Common Stock converted into Merger Consideration shall by

herein, no fractional shares of APP Common Stock will be issued and any
Stockholder otherwise entitled to receive a fractional share of APP Common Stock
as part of the Merger Consideration hereunder shall receive a cash payment in

APP Common Stock multiplied by the Initial Public Offering Price.

its business as currently conducted. The Company and each Company Subsidiary is
in good standing in each jurisdiction where the character of the property owned

or certificates of incorporation and all amendments thereto of the Company and
each Company Subsidiary and the bylaws of the Company and each Company
Subsidiary, as amended, and copies of the corporate minutes of the Company, all
of which have been or will be made available to APP for review, are true and

authorized by all necessary action on the part of the Company's Board of
Directors. Subject to the approval of this Agreement and the Merger by the
Stockholders, this Agreement has been duly executed by the Company, and this
Agreement and all other agreements and obligations entered into and undertaken
in connection with the transactions contemplated hereby to which the Company is
a party constitute, or upon execution will constitute, valid and binding
agreements of the Company, enforceable against it in accordance with their
respective terms, except as enforceability may be limited by bankruptcy or other
laws affecting the enforcement of creditors' rights generally, or by general
equity principles, or by public policy.

        Section 3.3 Governmental Authorization. Other than complying with the
provisions of the applicable state corporate laws regarding the approval of the
Merger and the filing of the Certificates of Merger (as contemplated by Section
2.3) and any other required documents related to the Merger, and other than

exemption from registration under (i) the Securities Act of 1933, as amended,
and (ii) all applicable state securities laws. No shares of Company Common Stock
are owned by the Company in treasury. No shares of Company Common Stock have
been issued or disposed of in violation of any preemptive rights, rights of
first refusal or similar rights of any of the Stockholders. Other than Company
Common Stock, the Company has no securities, bonds, debentures, notes or other
obligations the holders of which have the right to vote (or are convertible into

any matter.

Company, the execution, delivery and performance by the Company of this
Agreement and any other documents contemplated hereby (with or without the

actions, arbitrations, administrative or other proceedings, governmental
investigations or inquiries pending or, to the knowledge of the Company,
threatened against, or affecting the Company, any Company Subsidiary, any
Stockholder, the Physician Employees or any other licensed professional or other
individual affiliated with the Company affecting or that would reasonably be
likely to affect the Company Common Stock or the operations, business condition,

successful, may, individually or in the aggregate, have a Material Adverse
Effect on the Company or (ii) could adversely affect the ability of the Company
or any Company Subsidiary to effect the transactions contemplated hereby, and to
the knowledge of the Company there is no basis for any such action or any state
of facts or occurrence of any event which would reasonably be likely to give
rise to the foregoing. There are no unsatisfied judgments against the Company or
any Company Subsidiary or any licensed professional or other individual
affiliated with the Company or any Company Subsidiary relating to services

Company or any Company Subsidiary as in effect on the date hereof.

        Section 3.13 No Violation of Law. Neither the Company nor any Company

requirement of any governmental body, agency, authority or court binding on it,

        Section 3.14 Lease Agreements. The Disclosure Schedules contain a true,
accurate and complete list of all the lease agreements and license agreements to
which the Company or any Company Subsidiary is a party and pursuant to which the
Company or any Company Subsidiary leases (whether as lessor or lessee) or
licenses (whether as licensor or licensee) any real or personal property related
to the operation of its business and which requires payments in excess of
$12,000 per year (the "Lease Agreements"). The Company has delivered to APP true
and complete copies of all of the Lease Agreements. Each Lease Agreement is
valid, effective and in full force in accordance with its terms, and there is
not under any such lease (i) any existing or claimed material default by the
Company or any Company Subsidiary (as applicable) or event of material default
or event which with notice or lapse of time, or both, would constitute a
material default by the Company or any Company Subsidiary (as applicable) and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Company, or, (ii) to the knowledge of the Company, any existing
material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party. To the knowledge of the
Company, there is no pending or threatened reassessment of any property covered

reasonable good faith efforts to obtain, prior to the Effective Time, the
consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver to
APP in writing such consents as are necessary to effect a valid and binding
transfer or assignment of the Company's or any Company Subsidiary's rights
thereunder. The Company has a good, clear, valid and enforceable leasehold
interest under each of the Lease Agreements. The Lease Agreements comply with
the exceptions to ownership interests and compensation arrangements set out in
42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952, and any similar applicable
state law safe harbor or other exemption provisions.

        Section 3.15 Real and Personal Property.

all of its properties and assets (real, personal and mixed, tangible and
intangible) and any rights or interests therein


                                       11
<PAGE>   375
which it purports to own including, without limitation, all the property and
assets reflected in the Company Current Financial Statements; and (ii) owns such
rights, interests, assets and property free and clear of all Encumbrances, title
defects or objections (except for taxes not yet due and payable). The personal
property presently used in connection with the operation of the business of the
Company and the Company Subsidiaries constitutes the necessary personal property
assets to continue operation of the Company and any Company Subsidiary.

        Section 3.16 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, the Company does not have any
direct or indirect indebtedness for borrowed money, including indebtedness by
way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

        Section 3.17 Contracts and Commitments.

               (a) The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health
maintenance organization, other managed care organization or other third-party
provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of
obligations of third parties requiring the Company to make, or setting forth
conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000 in
any fiscal year or $25,000 in the aggregate and that are not cancelable by
providing notice of sixty (60) days or less. All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is with
unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP of the assets and
properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP. In every instance where consent is necessary, the Company
shall, on or before the Closing Date, use reasonable good faith efforts to
obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts. Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. Notwithstanding the foregoing, the Company shall not transfer to APP
any contracts or agreements relating to the provision of professional medical
services or other such agreements and contracts that APP consents to in writing
to be transferred to NewCo in the Spin-off Transaction. No contract with a
health care provider or Payor has been materially amended or terminated within
the last twelve (12) months.

state or federal agencies having jurisdiction over the items listed in the
Disclosure Schedules, either to revoke, withdraw or suspend any material license

unreasonably withheld) which by law either cannot be acquired or cannot be used
by APP because they relate to the practice of medicine or radiology, and shall
contribute to NewCo such other consideration and assets of the Company as may be
required under applicable law, in exchange for the issuance by NewCo of shares
of NewCo Common Stock, such shares being all of the issued and outstanding

<PAGE>   395
for inclusion in the Registration Statements, by exhibit or otherwise and (ii)
in the case of APP, will, at the time the Registration Statements and each
amendment and supplement thereto, if any, becomes effective under the Securities

statements therein, in the light of the circumstances under which they were
made, not misleading. The Company shall be entitled to review the Registration
Statements and each of the amendments thereto, if any, prior to the time each
becomes effective under the Securities Act. The Company shall have no
responsibility for information contained in the Registration Statements except

supplement or amend promptly the Disclosure Schedules with respect to any matter
that would have been or would be required to be set forth or described in the
Disclosure Schedules in order to not materially breach any representation,
warranty or covenant of such party contained herein; provided that no amendment
or supplement to a Disclosure Schedule that constitutes or reflects a Material
Adverse Effect on the Company may be made unless APP consents to such amendment
or supplement, and no amendment or supplement to a Disclosure Schedule that
constitutes or reflects a Material Adverse Effect on APP may be made unless the
Company consents to such amendment or supplement. For purposes of this
Agreement, including without limitation for purposes of determining whether the
conditions set forth in Sections 10.1 and 11.1 have been fulfilled, the
Disclosure Schedules hereto shall be deemed to be the Disclosure Schedules as

seeks to amend or supplement a Disclosure Schedule pursuant to this Section 9.2,

FTC or SEC.

        Section 9.5 Expenses. Each party to this Agreement shall be solely
responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by the Company and NewCo in connection with the Merger
shall be paid by the Company Stockholders in full immediately prior to the
Closing and such expenses shall be the sole responsibility of the Stockholders
following the Closing Date and not APP.

        Section 9.6 Patient Confidentiality. APP shall agree to keep all records
and information regarding the patients of the Company and NewCo confidential in
accordance with all applicable laws.

received by a Stockholder in the Merger (a "Reorganization").

shall be maintained, and all Tax Returns and schedules thereto shall be filed in
a manner consistent with the Merger being treated as a Reorganization. These
obligations are excused as to a party required to maintain the books or file a
Tax Return if such party has provided to the other parties a written opinion of
competent tax counsel to the effect that there is not substantial authority,
within the meaning of Section 6662(d)(2)(B)(i) of the Code, to report the Merger
as a Reorganization and such opinion either is furnished prior to the Effective
Time or is based on facts or events not known at the Effective Time. Each party
shall provide to each other party such tax information, reports, returns, or
schedules as may be reasonably required to assist such party in accounting for
and reporting the Merger as a Reorganization.

        (c) The parties agree that no Stockholder shall be liable for any taxes
incurred by the Company and for which APP has successor liability therefor which
arise solely as a result of the Merger or the consummation of the transactions
contemplated hereby; provided that the foregoing shall not limit


                                       37

or otherwise be deemed a waiver of any right of indemnification under Section
14.1 for a breach of any representation, warranty or covenant of the Company or
any Stockholder.

        Section 13.3 Current Public Information. APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

                                   ARTICLE XIV

                                    Remedies

        Section 14.1 Indemnification by the Company. Subject to the terms and
conditions of this Article XIV, the Company agrees to indemnify, defend and hold
APP and its respective directors, officers, stockholders, employees, agents,

damages, reasonable attorneys' fees and expenses (including, without limitation,
all costs of experts and all costs incidental to or in connection with any
appellate process) (collectively, "Damages") asserted against or incurred by
such individuals and/or entities arising out of or resulting from:

               (a) a breach by the Company of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of the Company
contained in this Agreement or in any Schedule or certificate delivered
thereunder;

               (b) any violation (or alleged violation) by the Company and/or

Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

               (c) any liability under the Securities Act, the Exchange Act or
any other federal or state "blue sky" or securities law or regulation, at common
law or otherwise, arising out of or based upon any (i) untrue statement of
material fact in any Registration Statement or any prospectus forming or part
thereof, or any amendment thereof or supplement thereto relating to the Company
(including any Company Subsidiary) or NewCo required to be stated therein or
(ii) failure to state information necessary to make the statements therein not
misleading, which untrue statement or failure to state information arises or
results solely from information provided in writing to APP or its counsel by the
Company or any Stockholder or their agents specifically for inclusion in any
such Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto.

        Section 14.2 Indemnification by APP. Subject to the terms and conditions
of this Article XIV, APP hereby agrees to indemnify, defend and hold the
Stockholders, the Company and NewCo and their respective directors, officers,
stockholders, employees, agents, attorneys, consultants and Affiliates harmless

and/or entities arising out of or resulting from:

giving effect to any Material Adverse Effect qualifier contained as part of any
such representation or warranty) or covenant of APP contained in this Agreement
or in any schedule or certificate delivered hereunder; and

               (b) any liability under the Securities Act, the Exchange Act or
any other federal or state "blue sky" or securities law or regulation, at common
law or otherwise, arising out of or based upon


                                       38
<PAGE>   402
any untrue statements of material fact in any Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or required to be stated therein or failure to state information
necessary to make the statements therein not misleading (except for any
liability based upon any actual or alleged untrue statement of material fact or
an omission to state a material fact relating to NewCo, the Company or any
Stockholder which was derived from any information provided in writing by the
Company or a Company Subsidiary or any of their agents contained in the
representations and warranties set forth in this Agreement or any certificate,
exhibit, schedule or instrument required to be delivered under this Agreement.)

               Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

        Section 14.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

               (a) Any party claiming indemnification under the Agreement (an
"Indemnified Party") shall promptly (and, in the event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party for whom indemnification is sought (the "Indemnifying
Party) of any third-party claim or claims asserted against the Indemnified Party
("Third Party Claim") that could give rise to a right of indemnification under
this Agreement and (ii) transmit to the Indemnifying Party a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of Damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement. The failure to promptly deliver a Claim Notice shall not relieve any
Indemnifying Party of its obligations to any Indemnified Party with respect to
the related Third Party Claim except to the extent that the resulting delay is
materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (x) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article XIV
with respect to such Third Party Claim and (y) whether the Indemnifying Party
desires, at the sole cost and expense of such Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

               (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may


                                       39
<PAGE>   403
employ separate counsel at the expense of the Indemnifying Party, and upon
written notification thereof, the Indemnifying Party shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Party shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

               (c) If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to it that are different from or additional
to those available to the Indemnified Party, then the Indemnifying Party may
employ separate counsel and upon written notification thereof, the Indemnified
Party shall not have the right to assume the defense of such action on behalf of
the Indemnifying Party.

               (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

               (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period


                                       40
<PAGE>   404
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

               (f) The Indemnifying Party shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Party to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Party desired to accept such settlement.

               (g) Notwithstanding any provision herein to the contrary, the
obligation of an Indemnifying Party to provide indemnification to an Indemnified
Party for breach of any representation or warranty as provided in Sections
14.1(a) or 14.2(a) hereof shall not take effect unless and until the Damages
asserted against or incurred in the aggregate and on a collective basis by the
Indemnified Parties pursuant to either Section 14.1 or 14.2 (as applicable) as a
result of such a breach or breaches exceeds $100,000.

        Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

        Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.

                                   ARTICLE XV

                                   Termination

in the event this Agreement is terminated pursuant to this Article XV, this
Agreement shall forthwith become void.

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

        Section 16.1 Non-Disclosure Covenant. The Company and NewCo recognize
and acknowledge that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP that is
valuable, special and a unique asset of such entity's business. APP acknowledges
that it had in the past, currently has, and in the future may possibly have,
access to certain Confidential Information of the Company and NewCo that is
valuable, special and a unique asset of each such business. The Company, NewCo
and APP, severally, agree that they will not disclose such Confidential
Information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
APP, NewCo and the Company and (b) to counsel and other advisers to APP, NewCo
and the Company provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 16.1, unless (i) such information
becomes available to or known by the public generally through no fault of the
Company, NewCo or APP, as the case may be, (ii) disclosure is required by law or
the order of any governmental authority under color of law, provided, that prior
to disclosing any information pursuant to this clause (ii) the Company, NewCo or
APP, as the case may be, shall, if possible, give prior written notice thereof
to the Company, NewCo or APP and provide the Company or APP with the opportunity
to contest such disclosure, (iii) the disclosing party reasonably believes that
such disclosure is required in connection with the defense of a lawsuit against
the disclosing party, or (iv) the disclosing party is the sole and exclusive
owner of such Confidential Information as a result of the Merger or otherwise.
In the event of a breach or threatened breach by the Company, on the one hand,
and APP, on the other hand, of the provisions of this Section, APP, NewCo and
the Company shall be entitled to an injunction restraining the other party, as
the case may be, from disclosing, in whole or in part, such Confidential
Information. Nothing herein shall be construed as prohibiting any of such
parties from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages.

        Section 16.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, NewCo and the Company agree that, in the event of
a breach by either of them of the foregoing covenant, the covenant may be
enforced against them by injunctions and restraining orders.

        Section 16.3 Survival. The obligations of the parties under this Article
XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                  Miscellaneous

or supplemented only by an instrument in writing executed by all the parties
hereto. Any waiver of any terms and conditions hereof must be in writing, and
signed by the parties hereto. The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining

therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable

or state securities law, the representations and warranties set forth therein

the laws of its state of organization, with all requisite power and authority to
own, operate and lease its assets and properties and to carry on its business as
currently conducted. Target Entity is in good standing in each jurisdiction
where the character of the property owned or leased by it or the nature of its
activities makes such qualification necessary, except where such failure to be
so qualified or in good standing would not have


                                       6
<PAGE>   424
a Material Adverse Effect on Target Entity. Copies of the Certificate of
[Limited] Partnership and all amendments thereto of Target Entity and the
[Limited] Partnership Agreement of Target Entity and all amendments thereto (the
"Partnership Agreement") and copies of the minutes of Target Entity, all of
which have been or will be made available to APP for review, are true and

        Section 3.2 Authorization and Validity. Target Entity has all requisite
right, power and authority to execute, deliver and perform this Agreement and
all agreements and other documents executed and delivered by it pursuant to this
Agreement or to be executed and delivered on the Closing Date, and has taken all
action required by law, its Certificate of [Limited] Partnership, its
Partnership Agreement or otherwise, to authorize the execution, delivery and
performance of this Agreement and such related documents. Seller has the legal
capacity to enter into and perform this Agreement and the other agreements to be
executed and delivered in connection herewith. This Agreement and all agreements
and documents executed and delivered in connection herewith have been, or will
be as of the Closing Date, duly executed and delivered by Seller and Target
Entity and constitute or will constitute the legal, valid and binding
obligations of Seller, enforceable against Seller and Target Entity in
accordance with their respective terms, except as may be limited by applicable
bankruptcy, insolvency or similar laws affecting creditors' rights generally or
by general equity principles, or by public policy.

        Section 3.3 Governmental Authorization. Other than consents, filings or
notifications required to be made or obtained solely by APP (including, without
limitation, in connection with the Initial Public Offering, Form S-4 or any
Hart-Scott-Rodino filing to be made by APP, if any), the execution, delivery and
performance by Seller and Target Entity of this Agreement and the agreements
provided for herein, and the consummation of the transactions contemplated
hereby and thereby by Seller and Target Entity requires no action by or in
respect of, or filing with, any governmental body, agency, official or
authority.

        Section 3.4 Capitalization and Title. The Sellers collectively are, and
will be immediately prior to the Closing Date, the record and beneficial owners
of all the issued and outstanding Partnership Units of Target Entity and Seller
is the owner of the Partnership Units currently held in his or her name on the
record books of Target Entity, free and clear of all Encumbrances. Each
Partnership Unit held by Seller has been legally and validly issued and is fully
paid and nonassessable, and was issued pursuant to a valid exemption from
registration under (i) the Securities Act and (ii) all applicable state
securities laws.

        Section 3.5 Transactions in Partnership Units. There exist no
Partnership Rights. Except for the General Partner Acquisition referenced
herein, Target Entity has no obligation (contingent or otherwise) to purchase,
redeem or otherwise acquire any of its partnership interests or to pay any
dividend or make any distribution in respect thereof. Neither the equity
structure of Target Entity nor the relative ownership of partnership interests
among any of its partners has been altered or changed in contemplation of the
Exchange within the two (2) years preceding the date of this Agreement.

        Section 3.6 Continuity of Business Enterprise. There has not been any
sale, distribution or spin-off of significant assets of Target Entity or any of
its Affiliates other than in the ordinary course of business within the two (2)

Agreement and any other documents contemplated hereby (with or without the

any governmental or regulatory body or authority or any other third party except
for such consents, for which the failure to obtain would not result in a
Material Adverse Effect on Target Entity; (ii) will not conflict with or result
in a violation of any provision of Target Entity's Certificate of [Limited]
Partnership or Partnership Agreement; (iii) will not conflict with, result in a
violation of, or constitute a default under any law, rule, ordinance, regulation
or any ruling, decree, determination, award, judgment, order or injunction of

are subject or bound; (iv) will not conflict with, constitute grounds for
termination of, result in a breach of, constitute a default under, require any

Material Adverse Effect on Target Entity; and (v) except as contemplated by this
Agreement, will not create any Encumbrance or restriction upon the Partnership

aggregate, have a Material Adverse Effect on Target Entity or (ii) could
adversely affect the ability of Target Entity or any Partnership Subsidiary to

other requirement of any governmental body, agency, authority or court binding

        Section 3.13 Lease Agreements. The Disclosure Schedules contain a true,
accurate and complete list of all the lease agreements and license agreements to
which Target Entity or any Partnership Subsidiary is a party and pursuant to
which Target Entity or any Partnership Subsidiary leases (whether as lessor or
lessee) or licenses (whether as licensor or licensee) any real or personal
property related to the operation of its business and which requires payments in
excess of $12,000 per year (the "Lease Agreements"). Target Entity has delivered
to APP true and complete copies of all of the Lease Agreements. Each Lease
Agreement is valid, effective and in full force in accordance with its terms,
and there is not under any such lease (i) any existing or claimed material
default by Target Entity or any Partnership Subsidiary (as applicable) or event
of material default or event which with notice or lapse of time, or both, would
constitute a material default by Target Entity or any Partnership Subsidiary (as
applicable) and, individually or in the aggregate, may reasonably result in a
Material Adverse Effect on Target Entity, or, (ii) to the knowledge of Seller
and Target Entity, any existing material default by any other party under any of
the Lease Agreements or any event of material default or event which with notice
or lapse of time, or both, would constitute a material default by any such
party. To the knowledge of Seller and Target Entity, there is no pending or
threatened reassessment of any property covered by the Lease Agreements. To the
extent necessary to accomplish the intent of the Agreement, Target Entity or any
Partnership Subsidiary shall use reasonable good faith efforts, and Seller shall
use reasonable good faith efforts to cause Target Entity, to obtain prior to the
Closing Date the consent of each landlord or lessor whose consent is required to
the assignment of the Lease Agreements and will use reasonable good faith
efforts to deliver to APP in writing such consents as are necessary to effect a
valid and binding transfer or assignment of Target Entity's or any Partnership
Subsidiary's rights thereunder. Target Entity has a good, clear, valid and
enforceable leasehold interest under each of the Lease Agreements. The Lease
Agreements comply with the exceptions to ownership interests and compensation
arrangements set out in 42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952,
and any similar applicable state law safe harbor or other exemption provisions.

        Section 3.14 Real and Personal Property.

               (a) Neither Target Entity nor each Partnership Subsidiary owns
any interest (other than the Lease Agreements) in real property.

title to all of its properties and assets (real, personal and mixed, tangible
and intangible) and any rights or interests therein which it purports to own;
and (ii) owns such rights, interests, assets and property free and clear of all
Encumbrances, title defects or objections (except for taxes not yet due and
payable). The personal property presently used in connection with the operation
of the business of Target Entity and each Partnership Subsidiary constitutes the
necessary personal property assets to continue operation of Target Entity and
each Partnership Subsidiary.

        Section 3.15 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, Target Entity does not have any
direct or indirect indebtedness for borrowed money, including indebtedness by
way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

        Section 3.16  Contracts and Commitments.

               (a) The Disclosure Schedules contain a true, accurate and
complete list, and Target Entity has delivered to APP true and complete copies,
of each contract, agreement and other instrument requiring Target Entity to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.22 or Lease Agreements
identified in Section 3.13) to which Target Entity is a party or by which it or
any of its properties or assets are bound including, without limitation, (i) all
agreements between Target Entity, on the one hand, and any government entity,
provider, hospital, health maintenance organization, other managed care
organization or other third-party provider, on the other hand, then in effect
relating to the provision of medical, diagnostic imaging or consulting services,
treatments, patient referrals or other similar activities, (ii) all indentures,
mortgages, notes, loan or credit agreements and other agreements and obligations
relating to the borrowing of money or to the direct or indirect guarantee or
assumption of obligations of third parties requiring Target Entity to make, or
setting forth conditions under which Target Entity would be required to make,
aggregate future payments in excess of $10,000 in any fiscal year or $25,000 in
the aggregate, (iii) all agreements for capital improvements or acquisitions
involving an amount of $75,000 in any fiscal year or $75,000 in the aggregate,
(iv) all agreements containing a covenant limiting the freedom of Target Entity
(or any provider employee of Target Entity) to compete in any line of business
with any person or entity or in any geographic area or (v) all written contracts
and commitments providing for future payments by Target Entity in excess of
$10,000 in any fiscal year or $25,000 in the aggregate and that are not
cancelable by providing notice of sixty (60) days or less. All such contracts,
agreements or other instruments are in full force and effect, there has been no
threatened cancellation thereof, there are no outstanding disputes thereunder,
each is with unrelated third parties and was entered into on an arms-length
basis in the ordinary course of business and, assuming the receipt of the
appropriate consents, all will continue to be binding in accordance with their
terms after consummation of the transaction contemplated herein; there are no
contracts, agreements or other instruments to which Target Entity is a party or
is bound (other than physician employment contracts and insurance policies)
which could either singularly or in the aggregate have a Material Adverse Effect
on the value to APP of the assets and properties to be acquired by APP from
Target Entity, or which could inhibit or prevent Target Entity from transferring
to or vesting in APP good and sufficient title to the assets and properties to
be acquired by APP except where the failure to transfer would not have a
Material Adverse Effect on APP. In every instance where consent is necessary, on
or before the Closing Date Target Entity shall use reasonable good faith
efforts, and Seller shall use reasonable good faith efforts to cause Target
Entity, to obtain and deliver to APP in writing, effective as of the Closing
Date, such consents as are necessary to enable APP to enjoy all of the rights
now enjoyed by Target Entity under such contracts. Any and all such consents

any plan or intention of any other party to exercise any right to cancel or
terminate any contract, agreement or instrument, and to the knowledge of Target
Entity and Seller there are no facts that would justify the exercise of such a

        existing on or prior to the date hereof or the Closing Date.

               "Hazardous Substances" shall mean any toxic or hazardous

any kind or nature necessary to be filed by Target Entity with any governmental
agency or authority have been properly completed and timely filed in compliance

        Section 3.22 Insurance Policies. The Disclosure Schedules list and
briefly describe Target Entity's policies of insurance to which Target Entity or
any Partnership Subsidiary is a party or under which Target Entity or any
Partnership Subsidiary, officer or director thereof is or has been covered at
any time during the last five (5) years preceding the date of this Agreement
relating to the business of Target Entity or any Partnership Subsidiary (the
"Insurance Policies"). All of the Insurance Policies are valid, outstanding and
enforceable policies, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies and all premiums with respect thereto which
are due and payable are currently paid. All Insurance Policies currently
maintained by Target Entity or any Partnership Subsidiary ("Current Policies")

properties and operations of Target Entity and its Affiliates for all risks
normally insured against by a Person carrying on a substantially similar

Closing Date. True, complete and correct copies of all Insurance Policies have
been provided to APP. Neither Target Entity nor any Partnership Subsidiary nor
any officer or partner thereof has received any notice or other written
communication from any issuer of any Current Policy cancelling such policy,
materially increasing any deductibles or retained amounts thereunder, or
materially increasing the annual or other premiums payable thereunder and, to
the knowledge of Seller and Target Entity, no such cancellation or increase of
deductibles, retainages or premiums is threatened. There are no outstanding
claims, settlements or premiums owed against any Insurance Policy, and all
required notices have been given and all known potential or actual claims under
any Insurance Policy have been presented in due and timely fashion. Within the
five (5) years preceding the Agreement, neither Target Entity nor any
Partnership Subsidiary


                                       13

receivable arose in the ordinary course of business and have not been previously
written off as bad debts and, are, to the extent still uncollected, to the
knowledge of Seller and Target Entity collectible in the ordinary course of
business, net of reserves for doubtful and uncollectible accounts shown on the

consistent with past practice).

providers of care to patients) which accounted for a dollar volume of purchases
paid for by Target Entity in excess of $25,000 for the fiscal year ended
[December 31, 1996], or which is reasonably expected to account for a dollar
volume of purchases paid for by Target Entity in excess of $25,000 for the
fiscal year to end [December 31, 1997].

        Section 3.25 Inventory. All items of inventory on hand on the date of
this Agreement consist, and all such items on hand on the Closing Date will
consist, net of all applicable reserves with respect thereto (calculated
consistent with past practice), of items of a quality and a quantity usable and
saleable in the ordinary course of Target Entity's business and conform to
generally accepted standards in the industry of which Target Entity is a part.

Target Entity and Seller has a current provider number for such Governmental
Programs and with such private non-governmental programs (including without

services provided by any licensed technician or contractor of Target Entity
(such non-governmental programs herein referred to as "Private Programs"). A

agreements is set forth in the Disclosure Schedules, true, complete and correct
copies of which have been provided to APP. No violation, default, order or
deficiency exists with respect to any of the items listed in the Disclosure
Schedules except for such violations, defaults, orders or deficiencies which
would not be reasonably likely to have a Material Adverse Effect on Target
Entity, and there is no action pending or to the knowledge of Seller and Target
Entity recommended by any state or federal agencies having jurisdiction over the
items listed in the Disclosure Schedules, either to revoke, withdraw or suspend
any material license or to terminate the participation of Target Entity in any
Governmental Program or Private Program, and no event has occurred which, with
or without notice or lapse of time, or both, would constitute grounds for a
violation, order or deficiency with respect to any of the items listed in the
Disclosure Schedules to revoke, withdraw or suspend any material license to
operate its business as is presently being conducted by it. To the knowledge of
Seller and Target Entity, there has been no decision not to renew any existing
agreement with any provider or Payor relating to Target Entity's business as
presently being conducted by it. Target Entity (i) has not had its professional
license, Drug Enforcement Agency number, Medicare/Medicaid provider status or

or authority, hospital, Payor or specialty board (including orders that have

result in any demand or reimbursement under the Medicare, Medicaid or Government

with a malpractice or similar action.

               (b) Target Entity is not required, or for the 72-month period
prior to the Closing Date was not required, to file any cost reports or other
reports with any Governmental Program or Private Program.

        Section 3.27 Inspections and Investigations. Neither the right of Target
Entity, nor the right of any licensed professional or other individual
affiliated with Target Entity to receive reimbursements pursuant to any
Governmental Program or Private Program has been terminated or otherwise
materially and adversely affected as a result of any investigation or action
whether by any federal or state governmental regulatory authority or other third
party. No licensed professional or other individual affiliated with the business
has, during the past three (3) years prior to the Closing Date, had their
professional license or staff privileges limited, suspended or revoked by any
governmental regulatory authority or agency, hospital, integrated delivery
system, trade association, professional review organization, accrediting
organization or certifying agency (including orders that have been entered by
any such entities but stayed). True, correct and complete copies of all reports,
correspondence, notices and other documents relating to any matter described or

corporation and is in good standing in each jurisdiction where the character of
the property owned or leased by it or the nature of its activities makes such

action on the part of APP's Board of Directors. This Agreement and the Other
Agreements have been duly executed by APP. This Agreement and all other
agreements and obligations entered into and undertaken in connection with the
transactions contemplated hereby to which APP is a party constitute, or upon
execution will constitute, valid and binding agreements of APP, enforceable
against it in accordance with their respective terms, except as may be limited
by bankruptcy or other laws affecting creditors' rights generally, or by general
equity principles, or by public policy.

        Section 4.3 Governmental Authorization. Other than consents, filings or
notifications required to be made or obtained solely by Target Entity, the
execution, delivery and performance by APP of this Agreement and the agreements

with, any governmental body, agency, official or authority.

        Section 4.4 Capitalization. The authorized capital stock of APP consists
of 20,000,000 shares of APP Common Stock, of which 2,000,000 shares are issued

validly issued and is fully paid and nonassessable, and was issued pursuant to a
valid exemption from registration under (i) the Securities Act, and (ii) all
applicable state securities laws. No shares of capital stock are owned by APP in
treasury. No shares of capital stock of APP have been

warrants, subscriptions, calls, commitments or other rights to purchase, or
securities convertible into or exchangeable for, any of the authorized or
outstanding securities of APP and no option, warrant, subscription, call, or
commitment or commission right of any kind exists which obligates APP to issue
any of its authorized but unissued capital stock. APP has no obligation
(contingent or otherwise) to purchase, redeem or otherwise acquire any of its
equity securities or any interests therein or to pay any dividend or make any
distribution in respect thereof.

        Section 4.5 Subsidiaries and Investments. APP does not own, directly or
indirectly, any capital stock or other equity, ownership or proprietary interest
in any corporation, partnership, association, trust, joint venture or other
entity (the "APP Subsidiaries").

execution, delivery and performance of this Agreement by APP and any other
documents contemplated hereby (with or without the giving of notice, the lapse
of time, or both): (i) does not require the consent of any governmental or
regulatory body or authority or any other third party except for such consents,
for which the failure to obtain would not result in a Material Adverse Effect on
APP; (ii) will not conflict with any provision of APP's Certificate of
Incorporation or Bylaws; (iii) will not conflict with, result in a violation of,
or constitute a default under any law, ordinance, regulation, ruling, judgment,

a party or by which APP or its properties are subject or bound; (iv) will not
conflict with, constitute grounds for termination of, result in a breach of,

the acceleration of any performance required by the terms of any agreement,

conflict, termination, breach or default, the occurrence of which would not
result in a Material Adverse Effect on APP; and (v) will not create any

        (a) Target Entity shall cooperate with APP to promptly prepare and file
with the SEC the Registration Statements on Form S-1 and Form S-4 (or other
appropriate Forms) to be filed by APP in connection with its Initial Public
Offering and offering of the shares of APP Common Stock to the Target Interest
Holders pursuant to the transactions contemplated by this Agreement and the
Other Agreements (including the prospectus constituting parts thereof, the

        (b) Seller, Target Entity and APP and each separately represent and

<PAGE>   444
by Seller and Target Entity specifically for inclusion in the Registration
Statements, by exhibit or otherwise and (ii) in the case of APP, will, at the
time the Registration Statements and each amendment and supplement thereto, if
any, becomes effective under the Securities Act, none of them contain any untrue
statement of a material fact or omit to state any material fact required to be

circumstances under which they were made, not misleading. Seller and Target
Entity shall be entitled to review the Registration Statements and each of the
amendments thereto, if any, prior to the time each becomes effective under the
Securities Act. Seller and Target Entity shall have no responsibility for
information contained in the Registration Statements except for information
provided by Seller or Target Entity specifically for inclusion therein. Seller's
and Target Entity's review of the Registration Statements shall not diminish or
otherwise affect the representations, covenants and warranties of APP contained
in this Agreement.

        (c) Seller and Target Entity shall, upon request, furnish APP with all
information concerning Target Entity, its subsidiaries, partners and officers,
and such other matters as may be reasonably requested by APP in connection with

party contained herein; provided that no amendment or supplement to a Schedule
that constitutes or reflects a Material Adverse Effect on Target Entity may be
made unless APP consents to such amendment or supplement, and no amendment or
supplement to a Schedule that constitutes or reflects a Material Adverse Effect
on APP may be made unless Sellers and Target Entity consent to such amendment or
supplement. For purposes of this Agreement, including without limitation for
purposes of determining whether the conditions set forth in Sections 8.1 and 9.1
have been fulfilled, the Disclosure Schedules hereto shall be deemed to be the
Disclosure Schedules as amended or supplemented pursuant to this Section 7.2. In

Schedule pursuant to this Section 7.2 and APP does not consent to such amendment
or supplement, or APP seeks to amend or supplement a Disclosure Schedule
pursuant to this Section 7.2, and Seller and Target Entity do not consent, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
13.1(a) hereof.

        Section 7.3 Actions Contrary to Stated Intent. No party hereto will
knowingly, either before or after the Closing Date, take any action that would
prevent the Exchange from qualifying as a tax-free exchange within the meaning
of Section 351 of the Code.

FTC or SEC.

responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees

<PAGE>   445
expenses incurred by Seller and Target Entity shall be paid by Seller in full
immediately prior to the Closing.

        Section 7.6 Registration Statements. APP shall prepare and file the
Registration Statements with the SEC, and shall use its reasonable good faith
efforts to cause the Registration Statements to become effective under the
Securities Act and take any action required to be taken under the applicable

        Section 11.1 Further Instruments of Transfer. Following the Closing, at
the request of APP and at APP's sole cost and expense, Seller and Target Entity
shall deliver any further instruments of transfer and take all reasonable action
as may be necessary or appropriate to carry out the purpose and intent of this

        Section 11.2 Exchange Tax Covenant.

               (a) The parties intend that the Exchange will qualify as a
tax-free transaction within the meaning of Section 351 of the Code in which the
Company will not recognize gain or loss, and pursuant to which any gain
recognized by Seller as a result of the Exchange will not exceed the amount of
any cash received by a Seller in the Exchange (a "Reorganization").

               (b) Both prior to and after the Closing Date, all books and
records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Exchange being treated as a
Reorganization. These obligations are excused as to a party required to maintain
the books or file a Tax Return if such party has provided to the other parties a
written opinion of competent tax counsel to the effect that there is not
substantial authority, within the meaning of Section 6662(d)(2)(B)(i) of the
Code, to report the Exchange as a Reorganization and such opinion either is
furnished prior to the Closing Date or is based on facts or events not known at
the Closing Date. Each party shall provide to each other party such tax
information, reports, returns, or schedules as may be reasonably required to
assist such party in accounting for and reporting the Exchange as a
Reorganization.

               (c) APP shall cause the requirements of Rule 144(c) under the
Securities Act to be met with respect to APP for so long as those requirements
must be met to enable sales by the Sellers who are affiliates of Target Entity
to meet the requirements of Rule 145(d) under the Securities Act.

                                   ARTICLE XII

                                    Remedies

        Section 12.1 Indemnification by Sellers. Subject to the terms,
limitations and conditions of this Agreement, Sellers (each an "Indemnifying
Party" and collectively, the "Indemnifying Parties"), severally, agree to
indemnify, defend and hold APP and its directors, officers, employees, agents,
attorneys, consultants and Affiliates (each an "Indemnified Party" and
collectively, the "Indemnified Parties"), harmless from and against all losses,
claims, obligations, demands, assessments, penalties, liabilities, costs,
damages, reasonable attorneys' fees and expenses (including, without limitation,
all costs of experts and all costs incidental to or in connection with any
appellate process) (collectively, "Damages") asserted against or incurred by an
Indemnified Party arising out of or resulting from:

               (a) a breach of any representation, warranty or covenant of any
Seller or Target Entity contained in this Agreement (without giving effect to
any Material Adverse Effect qualifier contained as part of any such
representation or warranty or covenant contained in this Agreement or in any
Schedule or certificate delivered hereunder);

               (b) any violation (or alleged violation) by any Seller or Target
Entity and/or any of its past or present directors, officers, partners,
employees, agents, attorneys, consultants and Affiliates


                                       32

of any state or federal law governing health care fraud and abuse or prohibition
on referral of patients to Persons in which a licensed professional has a
financial or other form of interest (including, but not limited to, fraud and
abuse in the Medicare and Medicaid Programs) occurring on or before the Closing
Date; and

               (c) any liability under the Securities Act, the Exchange Act or
any other federal or state "Blue Sky" or securities law or regulation, at common
law or otherwise, arising out of or based upon any (i) untrue statement of a
material fact in any Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto relating to Target
Entity (including any Partnership Subsidiary) or (ii) failure to state
information necessary to make the statements required to be stated therein not
misleading arising (in the case of either (i) or (ii)) solely from information
provided in writing to APP or its counsel by Target Entity or any Seller or
their agents specifically for inclusion in any such Registration Statement or
any prospectus forming a part thereof, or any amendment thereof or supplement
thereto (including, without limitation, schedules, exhibits and certifications
delivered by Target Entity or any of its agents in connection with this
Agreement).

        Notwithstanding anything herein to the contrary, nothing contained in
this Agreement shall relieve any Seller or Target Entity of any liability or
limit any liability that he, she or it may have in the case of fraud in
connection with the transactions contemplated by this Agreement.

        Section 12.2 Indemnification by APP. Subject to the terms, limitations
and conditions of this Agreement, APP (an "Indemnifying Party") hereby agrees to
indemnify, defend and hold the Sellers, and, as applicable, their respective
directors, partners, officers, stockholders, employees, agents, attorneys,
consultants and Affiliates (each an "Indemnified Party" and collectively, the
"Indemnified Parties") harmless from and against all Damages asserted against or
incurred by such individuals and/or entities arising out of or resulting from:

               (a) a breach by APP of any representation or warranty (without
giving effect to any Material Adverse Effect qualifier contained as part of any
such representation or warranty) or covenant of APP contained in this Agreement
or in any schedule or certificate delivered hereunder; and

               (b) any liability under the Securities Act, the Exchange Act or
any other federal or state "Blue Sky" or securities law or regulation, at common
law or otherwise, arising out of or based upon any (i) untrue statements of a
material fact in any Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or (ii) failure to
state information necessary to make the statements required to be stated therein
not misleading (except for any liability based upon any actual or alleged untrue
statement of material fact or an omission to state a material fact relating to
Target Entity or any Seller which was derived from any information provided in
writing by the Company or a Company Subsidiary or any of their agents contained
in the representations and warranties set forth in this Agreement or any
certificate, exhibit, schedule or instrument required to be delivered under this
Agreement.)

        Notwithstanding anything herein to the contrary, nothing contained in
this Agreement shall relieve APP of any liability or limit any liability that it
may have in the case of fraud in connection with the transactions contemplated
by this Agreement.

        Section 12.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:


                                       33
<PAGE>   451
               (a) The Indemnified Party shall promptly (and, in any event, at
least ten (10) days prior to the due date for any responsive pleadings, filings
or other documents) (i) notify each Indemnifying Party of any third-party claim
or claims asserted against the Indemnified Party ("Third Party Claim") that
could give rise to a right of indemnification under this Agreement and (ii)
transmit to the Indemnifying Parties a written notice ("Claim Notice")
describing in reasonable detail the nature of the Third Party Claim, a copy of
all papers served with respect to such claim (if any), an estimate of the amount
of Damages attributable to the Third Party Claim and the basis of the
Indemnified Party's request for indemnification under this Agreement. The
failure to promptly deliver a Claim Notice shall not relieve any Indemnifying
Party of its obligations to any Indemnified Party with respect to the related
Third Party Claim except to the extent that the resulting delay is materially
prejudicial to the defense of such claim. Within thirty (30) days after receipt
of any Claim Notice (the "Election Period"), the Indemnifying Parties shall
notify the Indemnified Party (x) whether the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement with respect
to such Third Party Claim and (y) whether the Indemnifying Parties desire, at
the sole cost and expense of each Indemnifying Party, to defend the Indemnified
Party against such Third Party Claim.

               (b) If the Indemnifying Parties notify the Indemnified Party
within the Election Period that the Indemnifying Parties elect to assume the
defense of the Third Party Claim, then the Indemnifying Parties shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party or Indemnified Parties, such Third Party
Claim by all appropriate proceedings, which proceedings shall be prosecuted
diligently by the Indemnifying Parties to a final conclusion or settled at the
discretion of the Indemnifying Parties in accordance with this Section 12.3(b).
Except as set forth in Section 12.3(f) below, the Indemnifying Parties shall
have full control of such defense and proceedings, including any compromise or
settlement thereof. The Indemnified Party is hereby authorized, at the sole cost
and expense of the Indemnifying Parties (but only if the Indemnified Party is
entitled to indemnification hereunder), to file, during the Election Period, any
motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Parties and not prejudicial to the Indemnifying Parties. If requested by the
Indemnifying Parties, the Indemnified Party agrees, at the sole cost and expense
of the Indemnifying Parties, to cooperate with the Indemnifying Parties and
their counsel in contesting any Third Party Claim that the Indemnifying Parties
elect to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person. The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Parties pursuant to this Section 12.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Parties and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Parties, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Parties, and upon written
notification thereof, the Indemnifying Parties shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Parties shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Parties shall be prohibited from confessing or settling any
criminal allegations brought against the Indemnified Party without the express
written consent of the Indemnified Party.


                                       34
<PAGE>   452
               (c) If the Indemnifying Parties fail to notify the Indemnified
Party within the Election Period that the Indemnifying Parties elect to defend
the Indemnified Party pursuant to Section 12.3(b), or if the Indemnifying
Parties elect to defend the Indemnified Party pursuant to Section 12.3(b) but
fail diligently and promptly to prosecute or settle the Third Party Claim, then
the Indemnified Party shall have the right to defend, at the sole cost and
expense of the Indemnifying Parties (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Parties to a final conclusion or settled. The Indemnified
Parties shall have full control of such defense and proceedings, provided,
however, that the Indemnified Parties may not enter into, without the
Indemnifying Parties' consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim. Notwithstanding the
foregoing, if the Indemnifying Parties have delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement and if such
dispute is resolved in favor of the Indemnifying Parties, the Indemnifying
Parties shall not be required to bear the costs and expenses of the Indemnified
Parties' defense pursuant to this paragraph or of the Indemnifying Party's
participation therein at the Indemnified Party's request, and the Indemnified
Party shall reimburse the Indemnifying Parties in full for all costs and
expenses of such litigation. The Indemnifying Parties may participate in, but
not control, any defense or settlement controlled by the Indemnified Party
pursuant to this Section 12.3(c), and the Indemnifying Parties shall bear their
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnifying Parties have been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnified Party, then the Indemnifying Parties may employ
separate counsel and upon written notification thereof, the Indemnified Party
shall not have the right to assume the defense of such action on behalf of the
Indemnifying Parties.

               (d) In the event any Indemnified Party should have a claim
against any Indemnifying Parties hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Parties a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification under
this Agreement. If the Indemnifying Parties do not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Parties dispute such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Parties hereunder. If the Indemnifying Parties have timely disputed such claim,
as provided above, such dispute shall be resolved by the procedures set forth in
Section 12.7.

               (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Agreement relating to a Third Party Claim shall be made within
thirty (30) days after the latest of (i) the settlement of such Third Party
Claim, (ii) the expiration of the period for appeal of a final adjudication of
such Third Party Claim, or (iii) the expiration of the period for appeal of a
final adjudication of the Indemnifying Parties liability to the Indemnified
Party under this Agreement. Payments of all amounts owing by the Indemnifying
Parties pursuant to Section 12.3(d) shall be made within thirty (30) days after
the later of (i) the expiration of the 60-day Indemnity Notice period or (ii)
the expiration of the period for appeal of a final adjudication of the
Indemnifying Parties liability to the Indemnified Party under this Agreement.
During the two-year period following the Closing Date, each Seller shall be
entitled to satisfy payments owed to APP by transfer of APP Common Stock from
such Seller to APP. For all purposes of this Agreement, the value of each share
of APP Common Stock transferred to APP pursuant to this Agreement shall be
calculated by averaging the daily closing prices for a share of APP Common Stock
for the twenty (20) consecutive trading days on which such shares are actually
traded on the Nasdaq


                                       35
<PAGE>   453
National Market preceding the date of the Claim Notice. The number of shares of
APP Common Stock permitted to be transferred under this Section 12.3(e) shall be
diminished proportionately in accordance with the percentage of APP Common Stock
released under the Lock-Up Provisions set forth herein. The rights of any Seller
to transfer shares of APP Common Stock in satisfaction of payments owed to APP
pursuant to this Agreement shall terminate upon the earlier of (x) the
termination of the Lock-Up Provisions set forth herein or (y) at the end of the
two-year period following the Closing Date.

               (f) The Indemnifying Parties shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Parties notify the Indemnified Party in writing that the Indemnifying Parties
agree to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Parties to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Parties desired to accept such settlement.

               (g) Notwithstanding anything contained in this Agreement to the
contrary, Indemnifying Parties in the aggregate (i) shall have no obligation
hereunder to provide indemnification for the first $__________ of Damages
(without counting Immaterial Claims as defined below), and (ii) in no event
shall the Indemnifying Parties have any liability hereunder with respect to any
singular incident or a fact involving a breach or inaccuracy of Target Entity if
the Damages from such claim are equal to or less than $__________ ("Immaterial
Claims"). Notwithstanding anything to the contrary contained herein, the
obligations of each Seller hereunder shall not exceed the value of the Exchange
Consideration paid to such Seller pursuant to the Related Acquisition, if any,
on the Closing Date.

        Section 12.4 Remedies Exclusive. The remedies provided in this Agreement
are the exclusive rights available to one party against the other, either at law
or in equity, except in the case of fraud.

        Section 12.5 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

        Section 12.6 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.

        Section 12.7 Dispute Resolution.

               (a) Arbitration. The parties hereto agree that any claim,
controversy, dispute or disagreement between or among any of the parties arising
out of or relating to this Agreement shall be governed exclusively by the terms
and provisions of this Section 12.7; provided, however, that within ten (10)
days from the date which any claim, controversy, dispute or disagreement cannot
be resolved and prior to commencing an arbitration procedure pursuant to this
Section 12.7, the parties shall meet to discuss and consider other alternative
dispute resolution procedures other than arbitration including,


                                       36
<PAGE>   454
but not limited to, Judicial Arbitration & Mediation Services, Inc., if
applicable. If at any time prior to the rendering of the decision by the
arbitrator (or pursuant to such other alternative dispute resolution procedure)
as contemplated in this Section 12.7 to the extent a party makes a written offer
to the other party proposing a settlement of the matter(s) at issue and such
offer is rejected, then the party rejecting such offer shall be obligated to pay
the costs and expenses (excluding the amount of the award granted under the
decision) of the party that offered the settlement from the date such offer was
received by such other party if the decision is for a dollar amount that is less
than the amount of such offer to settle. Notwithstanding the foregoing, the
terms and provisions of this Section 12.7 shall not preclude any party hereto
from seeking, or a court of competent jurisdiction from granting, a temporary
restraining order, temporary injunction or other equitable relief for any breach
of (i) any noncompetition or confidentiality covenant or (ii) any duty,
obligation, covenant, representation or warranty, the breach of which may cause
irreparable harm or damage.

               (b) Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among the parties hereto arising out of or relating to
this Agreement (including any claim based on or arising from an alleged tort)
and the parties hereto have not reached agreement regarding an alternative to
arbitration, the parties agree to select within thirty (30) days of notice by a
party to the other of its desire to seek arbitration under this Section 12.7 one
(1) arbitrator mutually acceptable to APP and the Sellers to hear and decide all
such claims under this Section 12.7. Each of the arbitrators proposed shall be
impartial and independent of all parties. If the parties cannot agree on the
selection of an arbitrator within said 30-day period, then any party may in
writing request the judge of the United States District Court for the [ ]
District of [ ] senior in term of service to appoint the arbitrator and, subject
to this Section 12.7, such arbitrator shall hear all arbitration matters arising
under this Section 12.7.

               (c) Applicable Rules.

                    (1) Each arbitration hearing shall be held at a place in [ ]
acceptable to the arbitrator. The arbitration shall be conducted in accordance
with the Commercial Arbitration Rules of the American Arbitration Association to
the extent such rules do not conflict with the terms hereof; provided, however,
that if the parties hereto agree to an alternative to arbitration they may agree
to an alternative set of rules, including as to rules of evidence and procedure.
The decision of the arbitrator shall be reduced to writing and shall be binding
on the parties and such decision shall contain a concise statement of the
reasons in support of such decision. Judgment upon the award(s) rendered by the
arbitrator may be entered and execution had in any court of competent
jurisdiction or application may be made to such court for a judicial acceptance
of the award and an order of enforcement. The charges and expenses of the
arbitrator shall be shared equally by the parties to the hearing.

                    (2) The arbitration shall commence within ten (10) days
after the arbitrator is selected in accordance with the provisions of this
Section 12.7. In fulfilling his duties with respect to determining the amount of
any loss, the arbitrator may consider such matters as, in the opinion of the
arbitrator, are necessary or helpful to make a proper valuation. The arbitrator
may consult with and engage disinterested third parties to advise the
arbitrator. The arbitrator shall not add any interest factor reflecting the time
value of money to the amount of any loss and shall not award any punitive
damages.

                    (3) If the arbitrator selected hereunder should die, resign
or be unable to perform his or her duties hereunder, the parties, or such senior
judge (or such judge's successor) in the event the parties cannot agree, shall
select a replacement arbitrator. The procedure set forth in this Section 12.7
for selecting the arbitrator shall be followed from time to time as necessary.

<PAGE>   455
                    (4) As to any determination of the amount of any loss, or as
to the resolution of any other claim, controversy, dispute or disagreement, that
under the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by the parties hereto, other
than to compel arbitration proceedings or enforce the award of the arbitrator,
except as otherwise provided in Section 12.7(b).

                    (5) All privileges under Texas and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying Texas law.

representation or warranty of any Seller or Target Entity contained in this
Agreement or in any certificate or other document executed and delivered by any
Seller or Target Entity pursuant to this Agreement is or becomes untrue or
breached in any material respect or if any Seller or Target Entity fails to
comply in any material respect with any material covenant or agreement contained
herein, and any such misrepresentation, noncompliance or breach is not cured,
waived or eliminated within thirty (30) days after receipt of written notice
thereof;

               (c) at any time prior to the Closing Date by Seller as to Seller
if any representation or warranty of APP contained in this Agreement or in any
certificate or other document executed and delivered by APP pursuant to this
Agreement is or becomes untrue in any material respect of if APP fails to comply
in any material respect with any covenant or agreement contained herein, and any
such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

               (d) at any time prior to the Closing Date by APP if, as a result
of the conduct of due diligence and regulatory compliance procedures, APP deems
termination to be advisable; or

               (e) by APP or Seller as to Seller if the Exchange shall not have
been consummated by September 30, 1997.

        Section 13.2 Effect of Termination. Except as set forth in Section 14.3,
in the event this Agreement is terminated pursuant to this Article XIV, this
Agreement shall forthwith become void.

                                   ARTICLE XIV

                    Nondisclosure of Confidential Information

        Section 14.1 Non-Disclosure Covenant. Seller and Target Entity recognize
and acknowledge that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP that is
valuable, special and a unique asset of such entity's business. APP


                                       38
<PAGE>   456
acknowledges that it had in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of Target Entity that
is valuable, special and a unique asset of each such business. Seller, Target
Entity and APP, severally, agree that they will not disclose such Confidential
Information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
APP, Seller and Target Entity and (b) to counsel and other advisers to APP,
Sellers and Target Entity provided that such advisers (other than counsel) agree
to the confidentiality provisions of this Section 14.1, unless (i) such
information becomes available to or known by the public generally through no
fault of Target Entity, Seller or APP, as the case may be, (ii) disclosure is
required by law or the order of any governmental authority under color of law,
provided, that prior to disclosing any information pursuant to this clause (ii)
Target Entity, Seller or APP, as the case may be, shall, if possible, give prior
written notice thereof to Target Entity, Seller or APP and provide Target
Entity, Seller or APP with the opportunity to contest such disclosure, (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, or (iv)
the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Exchange or otherwise. In the event of a breach
or threatened breach by Seller or Target Entity, on the one hand, and APP, on
the other hand, of the provisions of this Section, APP, Seller and Target Entity
shall be entitled to an injunction restraining the other party, as the case may
be, from disclosing, in whole or in part, such Confidential Information. Nothing
herein shall be construed as prohibiting any of such parties from pursuing any
other available remedy for such breach or threatened breach, including the
recovery of damages.

        Section 14.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, Seller and Target Entity agree that, in the event
of a breach by either of them of the foregoing covenant, the covenant may be
enforced against them by injunctions and restraining orders.

        Section 14.3 Survival. The obligations of the parties under this Article
XIV shall survive the termination of this Agreement.

                                   ARTICLE XV

or supplemented only by an instrument in writing executed by all the parties
hereto. Any waiver of any terms and conditions hereof must be in writing, and
signed by the parties hereto. The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

hereby or in any agreement entered into in connection with the transactions
contemplated hereby shall be assignable by any party hereto, except by APP to a

relieve APP of its obligations hereunder.

        Section 15.3 Parties in Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. Except as
otherwise provided herein, neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party hereto
or thereto any rights or remedies hereunder or thereunder.

contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

        Section 15.5 Severability. If any provision of this Agreement is held to
be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

by Target Entity, Seller and APP, respectively. Notwithstanding any provision in
this Agreement to the contrary, the representations and warranties contained

3.20 with respect to environmental matters shall survive for a period of ten
(10) years, (b) the representations and warranties set forth in Section 3.29
with respect to tax matters shall survive until such time as the limitations
period has run for all tax periods ended prior to the Closing Date, (c) the

shall keep this Agreement and its terms confidential, and shall make no press
release or public disclosure, either written or oral, regarding the transactions
contemplated by this Agreement without the prior knowledge and consent of the

Attn:     Paul M. Jolas, Senior Vice President
          and General Counsel

               Re:    Investment in American Physician Partners, Inc.

Dear Mr. Jolas:

               In connection with the receipt of shares of APP Common Stock (the
"Securities"), by the undersigned (the "Investor") pursuant to the Merger, the
Investor hereby represents, warrants, covenants and agrees as set forth below.
Except as otherwise expressly indicated herein, all capitalized terms shall have
the meanings set forth in that certain Agreement and Plan of Reorganization and
Merger dated as of __________, 1997, by and among American Physician Partners,
Inc. and ______________________________ (the "Agreement"):

               1. Lock-Up Provisions. Investor irrevocably agrees that he/she
will not, directly or indirectly, sell, offer, contract for sale, make any short
sale, pledge or otherwise transfer or dispose of any of the Securities without
the prior written consent of APP (which consent may be unreasonably withheld in
APP's absolute and sole discretion) during the two-year period commencing on the
Effective Date. Notwithstanding the preceding, the restrictions contained in the
prior sentence shall no longer apply (i) as to twenty-five percent (25%) of the
Securities received by Investor pursuant to the Merger following expiration of a
one-year period following the Effective Date, (ii) as to an additional
twenty-five percent (25%) of the Securities received by Investor pursuant to the
Merger following expiration of an eighteen-month period following the Effective
Date, and (iii) as to the remaining fifty percent (50%) of the Securities
received by Investor pursuant to the Merger following expiration of a
twenty-four-month period following the Effective Date. Investor understands and
acknowledges that the restrictions contained in this Paragraph 1 (the "Lock-Up
Provisions") are irrevocable and shall be binding upon the Investor's heirs,
legal representatives, successors and assigns.

               2. Restrictive Legends. Investor understands that the Securities
shall bear one or more of the following restrictive legends:

                        (a)     Any legend required to put third-parties on
                                notice of the existence of the Lock-Up
                                Provisions.

                        (b)     Any legend relating to affiliates of the Company
                                as required pursuant to the Securities and
                                Exchange Act of 1934.


<PAGE>   464
               3. Investor's Authority. In connection with the delivery and
surrender of the shares of Company Common Stock by Investor pursuant to the
Merger (i) Investor has full authority to surrender the certificate(s)
representing the shares of Company Common Stock free and clear of any and all
Encumbrances and (ii) the shares of Company Common Stock surrendered by Investor
in connection with the Merger constitute all of the shares of Company Common
Stock owned by Investor (beneficially or otherwise) and Investor does not own
(beneficially or otherwise) any Company Right.

               4. Filings; Other Action. Investor will cooperate with APP in
order that APP may promptly prepare and file with the SEC the Registration
Statements (including the prospectus constituting a part thereof). Investor
shall furnish all information concerning the Company and Investor as may be
reasonably requested in connection with any such action. None of the information
or documents supplied by Investor specifically for inclusion in the Registration
Statements, by exhibit or otherwise, will, at the time that any of the
Registration Statements and each amendment and supplement thereto, if any,
become effective under the Securities Act, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading. Investor shall be entitled to review
the Registration Statements and each amendment thereto, if any, prior to the
time each becomes effective under the Securities Act. Investor shall, upon
request, furnish APP with all information concerning Investor and the directors,
officers, partners and interestholders of the Company and NewCo, and such other
matters as may be reasonably requested by APP in connection with the preparation
of the Registration Statements and each amendment or supplement thereto, or any
other statement, filing, notice or application made by or on behalf of each such
party or any of its subsidiaries to any governmental entity in connection with
the Merger and the other transactions contemplated by the Agreement. Investor's
review of the Registration Statements shall not diminish or otherwise affect the
representations, covenants and warranties of APP or APP Sub contained in the
Agreement.

               5. Actions Contrary to Stated Intent. Investor has not and will
not take any action that would prevent the Merger or exchange transaction, as
the case may be, from qualifying as a tax-free transaction under Section 351
and/or Section 368 of the Code.

               6. Participation and Cooperation. Investor agrees to cooperate
with APP and the Company and any committees established by the Company in
connection with the formation and organization of Newco. In addition, Investor
agrees to review, provide and determine the truth and accuracy of all necessary
information regarding Investor and the Company which information shall be
provided to APP in connection with the registration process for the Initial
Public Offering and registration of APP Common Stock pursuant to the Form S-4.

               7. Involvement in Certain Legal Proceedings. Investor has not
been the subject of or a party to any of the following events during the past
five years and that are material to a voting or investment decision:

                    (a)  A petition under the Federal bankruptcy laws or any
                         State insolvency law was filed by or against, or a

                         by a court for the business or property of such person,
                         or any partnership in which he or she was a general
                         partner at or within two years before the time of such
                         filing, or any corporation

                    filing;

               (b)  Convicted in a criminal proceeding or is a named
                    subject of a pending criminal proceeding (excluding
                    traffic violations and other minor offenses);

               (c)  Any order, judgement, or decree, not subsequently
                    reversed, suspended or vacated, of any court of

               8. Prohibited Activities.

                    a. In order to protect the APP Group against the
unauthorized use or the disclosure of any of Confidential Information of any
member of the APP Group presently known or hereinafter obtained by Investor,
Investor hereby agrees that, subject to adjustment pursuant to Paragraph 8(e)
herein, for a period of two (2) years following the Closing Date, neither
Investor nor any of his/her Affiliates, shall knowingly, directly or indirectly,
for herself or himself or on behalf of any other Person (whether as an
individual, agent, servant, employee, employer, officer, director, shareholder,
investor, principal, consultant or in any other capacity):

                         (i) except for or on behalf of NewCo, within the
geographical area designated on Exhibit A hereto, establish, operate or provide
professional radiology, radiation oncology or diagnostic imaging services at any
office, practice or other health care facility providing services similar to
those provided by NewCo; or

                         (ii) without the prior written consent of APP: (1)
directly or indirectly recruit or hire, or induce any party to recruit or hire
any person who is an employee of, or who has entered into an independent
contractor arrangement with, any member of the APP Group; (2) directly or
indirectly, whether for itself or for any other person or entity, call upon,
solicit, divert or take away, or attempt to solicit, call upon, divert or take
away any customers, business, or clients of any member of the APP Group; (3)
directly or indirectly solicit, or induce any party to solicit, any contractors
of any member of the APP Group, to enter into the same or a similar type of
contract with any other party; or (4) disrupt, damage, impair or interfere with
the business of any member of the APP Group.

               The provisions of this Paragraph 8 shall be waived by APP in the
event of a purchase of assets by the Company pursuant to Article X of the
Service Agreement.

                    b. Because of the difficulty of measuring economic losses to
APP as a result of the breach of the covenants contained in this Paragraph 8,
and because of the immediate and irreparable damage that would be caused to APP
for which they would have no other adequate remedy, Investor agrees that, in the
event of a breach by him/her of the foregoing covenant, the covenant may be
enforced by APP by injunctions and restraining orders.

                    c. Investor acknowledges and agrees that the covenants
contained in this Paragraph 8 impose a reasonable restraint on Investor in light
of the activities and businesses of the APP Group on the date of execution of
this Agreement and the future plans of the APP Group.

                    d. The covenants in this Paragraph 8 are severable and
separate, and the unenforceability of any specific covenant shall not affect the
provisions of any other covenant. Moreover, in the event any court of competent
jurisdiction shall determine that the scope, time or territorial restrictions
set forth are unreasonable, then it is the intention of the parties that such
restrictions be enforced to the fullest extent that the court deems reasonable,
and this Paragraph 8 shall thereby be reformed.

                    e. It is specifically agreed that the period of two (2)
years stated above shall be computed by excluding from such computation any time
during which Investor is in violation of any provision of this Paragraph 8.

               9. Nondisclosure of Confidential Information.

                    a. Investor recognizes the proprietary interest of APP in
any Confidential and Proprietary Information (as hereinafter defined). Investor
acknowledges and agrees that any and all Confidential and Proprietary
Information of APP ("APP's Confidential and Proprietary Information")
communicated to, learned of, developed or otherwise acquired by Investor during
the term of the Employment Agreement shall be the property of APP. Investor
further acknowledges and understands that its disclosure of APP's Confidential
and Proprietary Information will result in irreparable injury and damage to APP.
As used in this Paragraph 9, "Confidential and Proprietary Information" means
all trade secrets and other confidential and/or proprietary information of APP,
including information derived from reports, investigations, research, work in
progress, codes, marketing and sales programs, financial projections, cost
summaries, pricing formula, contract analyses, financial information,
projections, confidential filings with any state or federal agency, and all
other confidential concepts, methods of doing business, ideas, materials or
information (other than patient records) prepared or performed for, by or on
behalf of the parties hereto by its employees, officers, directors, agents,
representatives, or consultants. Confidential and Proprietary Information shall
not include any information which: (i) was known to the parties hereto prior to
its disclosure by APP; (ii) is or becomes publicly known through no wrongful act
of Investor; (iii) is disclosed pursuant to a statute, regulation or the order
of a court of competent jurisdiction, provided that Investor provides prior
notice to APP.

                    b. Investor acknowledges and agrees that APP is entitled to
prevent the disclosure of Confidential and Proprietary Information. Investor
agrees at all times during the term of this Agreement and thereafter to hold in
strictest confidence and not to disclose to any person, firm or corporation,
except as may be necessary for the discharge of its obligations under the
Employment Agreement, and not to use, except in the pursuit of the business of
the practice, APP's Confidential and Proprietary Information, without the prior
written consent of APP; unless (i) such information becomes known or available
to the public generally through no wrongful act of Investor or (ii) disclosure
is required by law or the rule, regulation or order of any governmental
authority under color of law; provided, that prior to disclosing any of APP's
Confidential and Proprietary Information pursuant to this clause (iii), Investor
shall, if possible, give prior written notice thereof to APP and provide APP
with the opportunity to contest such disclosure. Investor shall take all
necessary and proper precautions against disclosure of any of APP's Confidential
and Proprietary Information to unauthorized persons by any of its officers,
directors, employees or agents. In the event Investor has access to all or any
part of APP's Confidential and Proprietary Information, Investor will be
required to execute an agreement upon request, valid under the law of the
jurisdiction in which such agreement is executed, and in a form acceptable to
APP and its counsel, committing themselves to maintain APP's Confidential and
Proprietary Information in strict confidence and not to disclose it to any
unauthorized person or entity. Upon termination of this Agreement for any
reason, Investor shall cease all use of any of APP's Confidential and
Proprietary Information and shall execute such documents as may be reasonably
necessary to evidence their abandonment of any claim thereto.

                    c. In the event of any termination of his/her Employment
Agreement for any reason whatsoever, or at any time upon the request of APP,
Investor will promptly deliver or cause to be delivered to APP all documents,
data and other information in their possession that contains any of APP's
Confidential and Proprietary Information regarding APP. Investor shall not take
or retain any documents or other information, or any reproduction or excerpt
thereof, containing any of APP's Confidential and Proprietary Information,
unless otherwise authorized in writing by the party possessing such Confidential
and Proprietary Information. In the event of termination of this


                                       5
<PAGE>   468
Agreement, Investor will deliver to APP all documents and data pertaining to
APP's Confidential and Proprietary Information.

               10. Address. The address set forth at the end of this letter is
his/her true and correct address.

                            INDEMNIFICATION AGREEMENT


               This INDEMNIFICATION AGREEMENT (the "Agreement") is entered into
this ___ day of ___________, 1997, by and between AMERICAN PHYSICIAN PARTNERS,
INC., a Delaware corporation ("APP"), and the individuals identified on Exhibit
A attached hereto (the "Stockholders"). Unless otherwise defined herein, all
capitalized terms shall have the meaning contained in that certain Agreement and
Plan of Reorganization and Merger dated ______________, 1997 (the "Merger
Agreement") by and among APP, APP Sub and _________________________, a
_____________ corporation (the "Company").

                                    RECITALS

               A. Concurrent with this Agreement, the Company shall enter into
the Merger Agreement and the Service Agreement whereby APP shall acquire the
assets, and manage the non-medical aspects of, the Company's radiology practice.

               B. Pursuant to Section ____ of the Merger Agreement, the
Stockholders have, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, agreed to execute and deliver this
Agreement to APP and APP Sub.

               NOW, THEREFORE, in consideration of the preceding recitals and
the covenants and agreements set forth herein, the parties agree as follows:

       1. Indemnification by the Stockholders. Subject to the terms, limitations
and conditions of this Agreement, the Stockholders (each an "Indemnifying Party"
and collectively, the "Indemnifying Parties"), severally, and not jointly, agree
to indemnify, defend and hold APP and its directors, officers, stockholders,
employees, agents, attorneys, consultants and Affiliates (each an "Indemnified
Party" and collectively, the "Indemnified Parties"), harmless from and against
all losses, claims, obligations, demands, assessments, penalties, liabilities,
costs, damages, reasonable attorneys' fees and expenses (including, without
limitation, all costs of experts and all costs incidental to or in connection
with any appellate process) (collectively, "Damages") asserted against or
incurred by an Indemnified Party arising out of or resulting from:

               a. a breach of any representation, warranty or covenant of the
Company contained in the Merger Agreement (without giving effect to any Material
Adverse Effect qualifier contained as part of any such representation or
warranty or covenant of the Company contained in the Merger Agreement or in any
Disclosure Schedule or certificate delivered thereunder);

               b. any violation (or alleged violation) by the Company and/or any
of its past or present directors, officers, partners, stockholders, employees
(including, without limitation, any Physician Employee), agents, attorneys,
consultants and Affiliates of any state or federal law governing health care
fraud and abuse or prohibition on referral of patients to Persons in which a
licensed professional has a financial or other form of interest (including, but
not limited to, fraud and abuse in the Medicare and Medicaid Programs) occurring
on or before the Closing Date, or any overpayment or obligation (or alleged
overpayment or obligation) arising out of or resulting from claims submitted to
any Payor on or before the Closing Date; and


                                       1
<PAGE>   471
               c. any liability under the Securities Act, the Exchange Act or
any other federal or state "blue sky" or securities law or regulation, at common
law or otherwise, arising out of or based upon any (i) untrue statement of a
material fact in any Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto relating to the Company
(including any Company Subsidiary) or NewCo or (ii) failure to state information
necessary to make the statements required to be stated therein not misleading,
which untrue statement or failure to state information arises or results solely
from information provided in writing to APP or its counsel by the Company or
such Stockholder or their agents specifically for inclusion in any such
Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto (including, without limitation,
schedules, exhibits and certifications delivered by the Company or any of its
agents in connection with the Merger Agreement).

               The provisions contained in Paragraph 2(g) shall not apply to
indemnification of claims listed in Exhibit B attached hereto. In addition,
notwithstanding anything herein to the contrary, nothing contained in this
Agreement shall relieve any of the Stockholders of any liability or limit any
liability that he or she may have in the case of fraud in connection with the
transactions contemplated by the Merger Agreement.

       2. Conditions of Indemnification. All claims for indemnification under
this Agreement shall be asserted and resolved as follows:

               a. The Indemnified Party shall promptly (and, in any event, at
least ten (10) days prior to the due date for any responsive pleadings, filings
or other documents) (i) notify each Indemnifying Party of any third-party claim
or claims asserted against the Indemnified Party ("Third Party Claim") that
could give rise to a right of indemnification under this Agreement and (ii)
transmit to the Indemnifying Parties a written notice ("Claim Notice")
describing in reasonable detail the nature of the Third Party Claim, a copy of
all papers served with respect to such claim (if any), an estimate of the amount
of Damages attributable to the Third Party Claim and the basis of the
Indemnified Party's request for indemnification under this Agreement. The
failure to promptly deliver a Claim Notice shall not relieve any Indemnifying
Party of its obligations to any Indemnified Party with respect to the related
Third Party Claim except to the extent that the resulting delay is materially
prejudicial to the defense of such claim. Within thirty (30) days after receipt
of any Claim Notice (the "Election Period"), the Indemnifying Parties shall
notify the Indemnified Party (x) whether the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement with respect
to such Third Party Claim and (y) whether the Indemnifying Parties desire, at
the sole cost and expense of each Indemnifying Party, to defend the Indemnified
Party against such Third Party Claim.

               b. If the Indemnifying Parties notify the Indemnified Party
within the Election Period that the Indemnifying Parties elect to assume the
defense of the Third Party Claim, then the Indemnifying Parties shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party or Indemnified Parties, such Third Party
Claim by all appropriate proceedings, which proceedings shall be prosecuted
diligently by the Indemnifying Parties to a final conclusion or settled at the
discretion of the Indemnifying Parties in accordance with this Paragraph 2(b).
Except as set forth in Paragraph 2(f) below, the Indemnifying Parties shall have
full control of such defense and proceedings, including any compromise or
settlement thereof. The Indemnified Party is hereby authorized, at the sole cost
and expense of the Indemnifying Parties (but only if the Indemnified Party is
entitled to indemnification hereunder), to file, during the Election Period, any
motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Parties and not prejudicial to the Indemnifying Parties. If requested by the


                                       2
<PAGE>   472
Indemnifying Parties, the Indemnified Party agrees, at the sole cost and expense
of the Indemnifying Parties, to cooperate with the Indemnifying Parties and
their counsel in contesting any Third Party Claim that the Indemnifying Parties
elect to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person. The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Parties pursuant to this Paragraph 2(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Parties and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Parties, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Parties, and upon written
notification thereof, the Indemnifying Parties shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Parties shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Parties shall be prohibited from confessing or settling any
criminal allegations brought against the Indemnified Party without the express
written consent of the Indemnified Party.

               c. If the Indemnifying Parties fail to notify the Indemnified
Party within the Election Period that the Indemnifying Parties elect to defend
the Indemnified Party pursuant to Paragraph 2(b), or if the Indemnifying Parties
elect to defend the Indemnified Party pursuant to Paragraph 2(b) but fail
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Parties (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Parties to a final conclusion or settled. The Indemnified
Parties shall have full control of such defense and proceedings, provided,
however, that the Indemnified Parties may not enter into, without the
Indemnifying Parties' consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim. Notwithstanding the
foregoing, if the Indemnifying Parties have delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement and if such
dispute is resolved in favor of the Indemnifying Parties, the Indemnifying
Parties shall not be required to bear the costs and expenses of the Indemnified
Parties' defense pursuant to this Paragraph or of the Indemnifying Party's
participation therein at the Indemnified Party's request, and the Indemnified
Party shall reimburse the Indemnifying Parties in full for all costs and
expenses of such litigation. The Indemnifying Parties may participate in, but
not control, any defense or settlement controlled by the Indemnified Party
pursuant to this Paragraph 2(c), and the Indemnifying Parties shall bear their
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnifying Parties have been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnified Party, then the Indemnifying Parties may employ
separate counsel and upon written notification thereof, the Indemnified Party
shall not have the right to assume the defense of such action on behalf of the
Indemnifying Parties.

               d. In the event any Indemnified Party should have a claim against
any Indemnifying Parties hereunder that does not involve a Third Party Claim,
the Indemnified Party shall transmit to the


                                       3
<PAGE>   473
Indemnifying Parties a written notice (the "Indemnity Notice") describing in
reasonable detail the nature of the claim, an estimate of the amount of damages
attributable to such claim and the basis of the Indemnified Party's request for
indemnification under this Agreement. If the Indemnifying Parties do not notify
the Indemnified Party within sixty (60) days from its receipt of the Indemnity
Notice that the Indemnifying Parties dispute such claim, the claim specified by
the Indemnified Party in the Indemnity Notice shall be deemed a liability of the
Indemnifying Parties hereunder. If the Indemnifying Parties have timely disputed
such claim, as provided above, such dispute shall be resolved by the procedures
set forth in Paragraph 7.

               e. Payments of all amounts owing by any Indemnifying Party
pursuant to this Agreement relating to a Third Party Claim shall be made within
thirty (30) days after the latest of (i) the settlement of such Third Party
Claim, (ii) the expiration of the period for appeal of a final adjudication of
such Third Party Claim, or (iii) the expiration of the period for appeal of a
final adjudication of the Indemnifying Parties liability to the Indemnified
Party under this Agreement. Payments of all amounts owing by the Indemnifying
Parties pursuant to Paragraph 2(d) shall be made within thirty (30) days after
the later of (i) the expiration of the 60-day Indemnity Notice period or (ii)
the expiration of the period for appeal of a final adjudication of the
Indemnifying Parties liability to the Indemnified Party under this Agreement.

                    (1) Within five (5) business days following distribution by
APP of a Claim Notice or Indemnity Notice, as the case may be, each Stockholder
shall elect the percentage of APP Common Stock he or she desires to allocate
(the "Stock Percentage Election") to satisfy any obligation to APP contained in
the Claim Notice or Indemnity Notice (the "Indemnification Obligation") and
shall submit such Stock Percentage Election in writing to APP at the address
listed in Paragraph 8 hereof or any other address requested by APP. Each
Stockholder shall be entitled to make a Stock Percentage Election equal to the
percentage of APP Common Stock currently subject to such Lock-Up Provisions (as
that term is defined below). By way of example, if the percentage of APP Common
Stock subject to the Lock-Up Provisions is seventy-five percent (75%) at the
time of a Claim Notice or Indemnity Notice, each Stockholder's Stock Percentage
Election may equal, but not exceed, seventy-five percent (75%) of the amount of
the Indemnification Obligation regardless of the Stock Percentage Elections
submitted by the other Stockholders. Failure to submit a complete Stock
Percentage Election within the time periods set forth in this Paragraph 2(e)
shall be deemed to be an election for such Stockholder to satisfy such
Indemnification Obligation with 100% cash.

               Each Stockholder's Stock Percentage Election shall be an
irrevocable election as to such Stockholder of the method of payment of the
applicable Indemnification Obligation, and such percentage election between APP
Common Stock and cash shall remain constant with respect to the final payment of
the Indemnification Obligation. Following each Stockholder's Stock Percentage
Election, each Stockholder shall, in APP's sole discretion, either (i) transfer
the Reserved APP Stock (as that term is defined below) to an escrow account (the
"Escrow Account") established by APP or (ii) consent to a stop transfer of such
APP Common Stock by APP to be either (x) held in the Escrow Account or (y)
subject to such stop order, as the case may be, until final payment of the
Indemnification Obligation as set forth in Paragraph 2(e)(4).

               The remaining portion of the Indemnification Obligation not
satisfied by the Stock Percentage Election shall be valued in cash, however, the
cash portion shall not be transferred to the Escrow Account. By way of example,
if the Stock Percentage Election is 75%, the remaining 25% of the
Indemnification Obligation shall be paid in cash.

                    (2) For purposes of this Agreement only and in order to
calculate the actual number of shares of Reserved APP Stock to be held in the
Escrow Account or subject the a stop order, the value of each share of APP
Common Stock transferred to the Escrow Account or be subject to a stop transfer
pursuant to the Stock Percentage Election shall be calculated by averaging the
daily closing prices for a share of APP Common Stock for the twenty (20)
consecutive trading days on which such shares are actually traded on the Nasdaq
National Market (or other national securities exchange or inter-dealer quotation
system) preceding the date of the Claim Notice or Indemnity Notice, as the case
may be (the "APP Stock Price").

                    (3) The number of shares to be reserved by the transfer to
the Escrow Account or subject to a stop transfer to satisfy the Indemnification
Obligation (the "Reserved APP Stock") shall be calculated by APP according to
the following formula:

                         (i) Determine the dollar amount of each Stockholder's
proportionate amount of the Indemnification Obligation ("Proportionate
Obligation");

                         (ii) Multiply the Proportionate Obligation by the Stock
Percentage Election to determine the dollar value of the Stock Percentage
Election ("Stock Election Value"); and

                         (iii) Divide the Stock Election Value by the APP Stock
Price to determine the Reserved APP Stock.

Except as set forth herein, the Reserved APP Stock shall remain constant until
the final payment of any Indemnification Obligation. To determine the amount of
cash required to satisfy the Proportionate Obligation, subtract the Stock
Election Value from the Proportionate Obligation.

                    (4) On the final payment date pursuant to this Paragraph
2(e) (the "Actual Payment Date"), the parties hereto will be notified of the
actual dollar amount of the Indemnification Obligation. On the Actual Payment
Date, if the amount owing by each Stockholder (1) equals the Proportionate
Obligation, then all of the Reserved APP Stock and the cash portion of the
Proportionate Obligation shall be transferred to APP, (2) is less than the
Proportionate Obligation, then the percentage of the Reserved APP Stock and cash
that is required to satisfy the actual Indemnification Obligation shall be
determined by multiplying (a) the total amount of the actual Indemnification
Obligation applicable to each Stockholder divided by the Proportionate
Obligation by the (b) number of shares of Reserved APP Stock for such
Stockholder and (c) the amount of cash that would have been required to satisfy
his or her Proportionate Obligation, or (3) is greater than the amount of the
Proportionate Obligation, then (a) all of the Reserved APP Stock and cash that
would have been required to satisfy his or her Proportionate Obligation, plus
(b) the amount by which the actual Indemnification Obligation for such
Stockholder exceeds the Proportionate Obligation, which additional amount shall
be payable by such Stockholder in cash, shall be transferred to APP. By way of
example, assume that (i) the amount of the Proportionate Obligation as of the
date of the Claim Notice or Indemnity Notice was equal to $100,000, (ii) such
Stockholder's Stock Election Percentage was 75%, and (iii) the APP Stock Price
was $15.00. The number of shares required to be placed into the Escrow Account
or subject to a stop transfer by such Stockholder would be 5,000 shares of APP
Common Stock ($100,000 X 75%/$15.00). If the actual Indemnification Obligation
was (1) $100,000, then all of the Reserved APP Stock, regardless of the
then-current trading price of the APP Common Stock, plus $25,000 cash would be
required to be transferred to APP, (2) $50,000, which is 50% of the
Proportionate Obligation, then 50% of the Reserved APP Stock held in the Escrow
Account or subject to a stop transfer (5,000 shares X 50%), or 2,500 shares,
regardless of the then-current trading price of APP Common Stock, plus $12,500
cash would be required


                                       5
<PAGE>   475
to be transferred to APP, or (3) $150,000, then all of the Reserved APP Stock
held in the Escrow Account or subject to a stop transfer, regardless of the
then-current trading price of APP Common Stock, $25,000 cash, plus an additional
$50,000 cash (the difference between the actual Indemnification Obligation and
the Proportionate Obligation) would be required to be transferred to APP.

All payments of cash in satisfaction of the actual Indemnification Obligation
pursuant to this Indemnification Agreement shall be made to APP by cashier's
check.

                    (5) Notwithstanding any provision contained herein to the
contrary, (1) each Stockholder shall be entitled to transfer to APP shares of
APP Common Stock held by such Stockholder which are subject to the Lock-Up
Provisions contained in Paragraph 1 of the Stockholder Representation Letter
("Lock-Up Provisions") and (2) the provisions of Paragraphs 2(e)(1) through (5)
shall have no further force or effect, and shall not apply in any manner
whatsoever, with respect to any Claim Notice or Indemnity Notice which is given
subsequent to the earlier of (x) the termination of the Lock-Up Provisions or
(y) the end of the two (2) year period following the Effective Date.

               f. The Indemnifying Parties shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Parties notify the Indemnified Party in writing that the Indemnifying Parties
agree to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Parties to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Parties desired to accept such settlement.

               g. Notwithstanding anything contained in this Agreement or the
Merger Agreement to the contrary, the Indemnifying Parties in the aggregate (i)
shall have no obligation hereunder to provide indemnification for the first
$100,000 of Damages (without counting Immaterial Claims as defined below), and
(ii) in no event shall the Indemnifying Parties have any liability hereunder
with respect to any singular incident or a fact involving a breach or inaccuracy
of the Company if the Damages from such claim are equal to or less than $7,500
("Immaterial Claims"). Notwithstanding anything to the contrary contained herein
or in the Merger Agreement, the obligations of each Stockholder hereunder shall
not exceed fifty percent (50%) of the aggregate value of the Merger
Consideration or Exchange Consideration, as the case may be, paid to such
Stockholder pursuant to any Related Acquisition on the Closing Date.

       3. Intentionally Omitted.

       4. Remedies Exclusive. The remedies provided in this Agreement are the
exclusive rights or remedies available to one party against the other arising
out of or with respect to the Merger Agreement, either at law or in equity,
except in the case of fraud.

       5. Costs, Expenses and Legal Fees. Whether or not the transactions
contemplated hereby are consummated, each party hereto shall bear its own costs
and expenses (including attorneys' fees), except that each party hereto agrees
to pay the costs and expenses (including reasonable attorneys' fees and
expenses) incurred by the other parties in successfully (a) enforcing any of the
terms of this Agreement or (b) proving that another party breached any of the
terms of this Agreement.


                                       6
<PAGE>   476
       6. Tax Benefits; Insurance Proceeds. The total amount of any indemnity
payments owed by one party to another party to this Agreement shall be reduced
by any correlative tax benefit received by the party to be indemnified or the
net proceeds received by the party to be indemnified with respect to recovery
from third parties or insurance proceeds, and such correlative insurance benefit
shall be net of the insurance premium, if any, that becomes due as a result of
such claim.

       7. Dispute Resolution.

               a. Arbitration. The parties hereto agree that any claim,
controversy, dispute or disagreement between or among any of the parties arising
out of or relating to this Agreement shall be governed exclusively by the terms
and provisions of this Paragraph 7; provided, however, that within ten (10) days
from the date any party gives notice to the others of its desire to seek
arbitration as provided in Paragraph 7(b) and prior to commencing an arbitration
procedure pursuant to this Paragraph 7, the parties shall meet to discuss and
consider alternative dispute resolution procedures other than arbitration
including, but not limited to Judicial Arbitration & Mediation Services, Inc.,
if applicable. If at any time prior to the rendering of the decision by the
arbitrator (or pursuant to such other alternative dispute resolution procedure)
as contemplated in this Paragraph 7 to the extent a party makes a written offer
to an opposing party proposing a settlement of the matter(s) at issue and such
offer is rejected, then the party rejecting such offer shall be obligated to pay
the costs and expenses (excluding the amount of the award granted under the
decision) of the party that offered the settlement from the date such offer was
received by such other party if the decision is for a dollar amount that is less
than the amount of such offer to settle. Notwithstanding the foregoing, the
terms and provisions of this Paragraph 7 shall not preclude any party hereto
from seeking, or a court of competent jurisdiction from granting, a temporary
restraining order, temporary injunction or other equitable relief for any breach
of (i) any noncompetition or confidentiality covenant or (ii) any duty,
obligation, covenant, representation or warranty, the breach of which may cause
irreparable harm or damage.

               b. Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among the parties hereto arising out of or relating to
this Agreement (including any claim based on or arising from an alleged tort)
and the parties hereto have not reached agreement regarding an alternative to
arbitration, the parties agree to select, within 30 days of notice by a party to
the other of its desire to seek arbitration under this Paragraph 7 one (1)
arbitrator mutually acceptable to the Company and the Stockholders to hear and
decide all such claims under this Paragraph 7. Each of the arbitrators proposed
shall be impartial and independent of all parties. If the parties cannot agree
on the selection of an arbitrator within said 30-day period, then any party may
in writing request the judge of the United States District Court for the
_____________ District of __________ senior in term of service to appoint the
arbitrator and, subject to this Paragraph 7, such arbitrator shall hear all
arbitration matters arising under this Paragraph 7.

               c. Applicable Rules.

                    (1) Each arbitration hearing shall be held at a place in
_____________ acceptable to the arbitrator. The arbitration shall be conducted
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association to the extent such rules do not conflict with the terms hereof;
provided, however, that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including as to rules
of evidence and procedure. The decision of the arbitrator shall be reduced to
writing and shall be binding on the parties and such decision shall contain a
concise statement of the reasons in support of such decision. Judgment upon the
award(s) rendered by the arbitrator may be entered and execution had in any
court of competent jurisdiction or


                                       7
<PAGE>   477
application may be made to such court for a judicial acceptance of the award and
an order of enforcement. The charges and expenses of the arbitrator shall be
shared equally by the parties to the hearing.

                    (2) The arbitration shall commence within ten (10) days
after the arbitrator is selected in accordance with the provisions of this
Paragraph 7. In fulfilling his duties with respect to determining the amount of
any loss, the arbitrator may consider such matters as, in the opinion of the
arbitrator, are necessary or helpful to make a proper valuation. The arbitrator
may consult with and engage disinterested third parties to advise the
arbitrator. The arbitrator shall not add any interest factor reflecting the time
value of money to the amount of any loss and shall not award any punitive
damages.

                    (3) If the arbitrator selected hereunder should die, resign
or be unable to perform his or her duties hereunder, the parties, or such senior
judge (or such judge's successor) in the event the parties cannot agree, shall
select a replacement arbitrator. The procedure set forth in this Paragraph 7 for
selecting the arbitrator shall be followed from time to time as necessary.

                    (4) As to any determination of the amount of any loss, or as
to the resolution of any other claim, controversy, dispute or disagreement, that
under the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by the parties hereto, other
than to compel arbitration proceedings or enforce the award of the arbitrator,
except as otherwise provided in Paragraph 7.

                    (5) All privileges under state and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying state law.

supplemented only by an instrument in writing executed by all the parties

hereby or in any agreement entered into in connection with the transactions

                                       8
<PAGE>   478
severable and this Agreement shall be construed and enforced as if such illegal,
invalid or unenforceable provision never comprised a part hereof; and the
remaining provisions hereof shall remain in full force and effect and shall not
be affected by the illegal, invalid or unenforceable provision or by its
severance therefrom. Furthermore, in lieu of such illegal, invalid or
unenforceable provision, there shall be added automatically as part of this
Agreement a provision as similar in its terms to such illegal, invalid or
unenforceable provision as may be possible and be legal, valid and enforceable.

               f. Governing Law. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN

                           SECTIONS 1300 THROUGH 1304


Section 1300. Reorganization or short-form merger; dissenting shares; corporate
purchase at fair market value; definitions

(a) If the approval of the outstanding shares (Section 152) of a corporation is
required for a reorganization under subdivisions (a) and (b) or subdivision (e)
or (f) of Section 1201, each shareholder of the corporation entitled to vote on
the transaction and each shareholder of a subsidiary corporation in a short-form
merger may, by complying with this chapter, require the corporation in which the
shareholder holds shares to purchase for cash at their fair market value the
shares owned by the shareholder which are dissenting shares as defined in
subdivision (b). The fair market value shall be determined as of the day before
the first announcement of the terms of the proposed reorganization or short-form
merger, excluding any appreciation or depreciation in consequence of the
proposed action, but adjusted for any stock split, reverse stock split, or share
dividend which becomes effective thereafter.

(b) As used in this chapter, "dissenting shares" means shares which come within
all of the following descriptions:

(1) Which were not immediately prior to the reorganization or short-form merger
either (A) listed on any national securities exchange certified by the
Commissioner of Corporations under subdivision (0) of Section 25100 or (B)
listed on the list of OTC margin stocks issued by the Board of Governors of the
Federal Reserve System, and the notice of meeting of shareholders to act upon
the reorganization summarizes this section and Sections 1301, 1302, 1303 and
1304; provided, however, that this provision does not apply to any shares with
respect to which there exists any restriction on transfer imposed by the
corporation or by any law or regulation; and provided, further, that this
provision does not apply to any class of shares described in subparagraph (A) or
(B) if demands for payment are filed with respect to 5 percent or more of the
outstanding shares of that class.

(2) Which were outstanding on the date for the determination of shareholders
entitled to vote on the reorganization and (A) were not voted in favor of the
reorganization or, (B) if described in subparagraph (A) or (B) of paragraph (1)
(without regard to the provisos in that paragraph), were voted against the
reorganization, or which were held of record on the effective date of a
short-form merger; provided, however, that subparagraph (A) rather than
subparagraph (B) of this paragraph applies in any case where the approval
required by Section 1201 is sought by written consent rather than at a meeting.

(3) Which the dissenting shareholder has demanded that the corporation purchase
at their fair market value, in accordance with Section 1301.

(4) Which the dissenting shareholder has submitted for endorsement, in
accordance with Section 1302.

(c) As used in this chapter, "dissenting shareholder" means the recordholder of
dissenting shares and includes a transferee of record.

Section 1301. Notice to holders of dissenting shares in reorganizations; demand
for purchase; time; contents

(a) If, in the case of a reorganization, any shareholders of a corporation have
a right under Section 1300, subject to compliance with paragraphs (3) and (4) of
subdivision (b) thereof, to require the corporation to purchase their shares for
cash, such corporation shall mail to each such shareholder a notice of the
approval of the reorganization by its outstanding shares (Section 152) within 10
days after the date of such approval, accompanied by a copy of Sections 1300,
1302, 1303, 1304 and this section, a statement of the price determined by the
corporation to represent the fair market value of the dissenting shares, and a
brief description of the procedure to be followed if the shareholder desires to
exercise the shareholder's right under such sections. The statement of price
constitutes an offer by the corporation to purchase at the price stated any
dissenting shares as defined in subdivision (b) of Section 1300, unless they
lose their status as dissenting shares under Section 1309.

(b) Any shareholder who has a right to require the corporation to purchase the
shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.

(c) The demand shall state the number and class of the shares held of record by
the shareholder which the shareholder demands that the corporation purchase and
shall contain a statement of what such shareholder claims to be the fair market
value of those shares as of the day before the announcement of the proposed
reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

Section 1302. Submission of share certificates for endorsement; uncertificated
securities

Within 30 days after the date on which notice of the approval by the outstanding
shares or the notice pursuant to subdivision (i) of Section 1110 was mailed to
the shareholder, the shareholder shall submit to the corporation at its
principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.


<PAGE>   485
Section 1303. Payment of agreed price with interest; agreement fixing fair
market value; filing; time of payment

(a) If the corporation and the shareholder agree that the shares are dissenting
shares and agree upon the price of the shares, the dissenting shareholder is
entitled to the agreed price with interest thereon at the legal rate on
judgments from the date of the agreement. Any agreements fixing the fair market
value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

(b) Subject to the provisions of Section 1306, payment of the fair market value
of dissenting shares shall be made within 30 days after the amount thereof has
been agreed or within 30 days after any statutory or contractual conditions to
the reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.

Section 1304. Action to determine whether shares are dissenting shares or fair
market value; limitation; joinder; consolidation; determination of issues;
appointment of appraisers

(a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder fail to agree upon the fair market value of the
shares, then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares or the
fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.

(b) Two or more dissenting shareholders may join as plaintiffs or be joined as
defendants in any such action and two or more such actions may be consolidated.

(c) On the trial of the action, the court shall determine the issues. If the
status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

                 KANSAS GENERAL CORPORATION CODE SECTION 17-6712


17-6712. Payment for stock of stockholder objecting to merger or consolidation;
definitions; notice to objecting stockholders; demand for payment; appraisal and
determination of value by district court, when [sic]; taxation of costs; rights
of objecting stockholders; status of stock; section inapplicable to certain
shares of stock.

            (a) When used in this section, the word "stockholder" means a holder
of record of stock in a stock corporation and also a member of record of a
nonstock corporation; the words "stock" and "share" mean and include what is
ordinarily meant by those words and also membership or membership interest of a
member of a nonstock corporation.

            (b) The corporation surviving or resulting from any merger or
consolidation, within 10 days after the effective date of the merger or
consolidation, shall notify each stockholder of any corporation of this state so
merging or consolidating who objected thereto in writing and whose shares either
were not entitled to vote or were not voted in favor of the merger or
consolidation, and who filed such written objection with the corporation before
the taking of the vote on the merger or consolidation, that the merger or
consolidation has become effective. If any such stockholder, within 20 days
after the date of mailing of the notice, shall demand in writing, from the
corporation surviving or resulting from the merger or consolidation, payment of
the value of the stockholder's stock, the surviving or resulting corporation
shall pay to the stockholder, within 30 days after the expiration of the period
of 20 days the value of the stockholder's stock on the effective date of the
merger or consolidation, exclusive of any element of value arising from the
expectation or accomplishment of the merger or consolidation.

            (c) If during a period of 30 days following the period of 20 days
provided for in subsection (b), the corporation and any such stockholder fail to
agree upon the value of such stock, any such stockholder, or the corporation
surviving or resulting from the merger or consolidation, may demand a
determination of the value of the stock of all such stockholders by an appraiser
or appraisers to be appointed by the district court, by filing a petition with
the court within four months after the expiration of the thirty-day period.

            (d) Upon the filing of any such petition by a stockholder, service
of a copy thereof shall be made upon the corporation, which shall file with the
clerk of such court, within 10 days after such service, a duly verified list
containing the names and addresses of all stockholders who have demanded payment
for their shares and with whom agreements as to the value of their shares have
not been reached by the corporation. If the petition shall be filed by the
corporation, the petition shall be accompanied by such duly verified list. The
clerk of the court shall give notice of the time and place fixed for the hearing
of such petition by registered or certified mail to the corporation and to the
stockholders shown upon the list at the addresses therein stated and notice
shall also be given by publishing a notice at least once, at least one week
before the day of the hearing, in a newspaper of general circulation in the
county in which the court is located. The court may direct such additional
publication of notice as it deems advisable. The forms of the notices by mail
and by publication shall be approved by the court.

            (e) After the hearing on such petition the court shall determine the
stockholders who have complied with the provisions of this section and become
entitled to the valuation of and payment for their shares, and shall appoint an
appraiser or appraisers to determine such value. Any such appraiser may examine
any of the books and records of the corporation or corporations the stock of
which such appraiser is charged with the duty of valuing, and such appraiser
shall make a determination of the value of the shares upon such investigation as
seems proper to the appraiser. The appraiser or appraisers shall also afford a
reasonable opportunity to the parties interested to submit to the appraiser or
appraisers pertinent evidence on the value of the shares. The appraiser or
appraisers, also, shall have the powers and authority conferred upon masters by
K.S.A. 60-253 and amendments thereto.

            (f) The appraiser or appraisers shall determine the value of the
stock of the stockholders adjudged by the court to be entitled to payment
therefor and shall file a report respecting such value in the office of the
clerk


<PAGE>   488
of the court, and notice of the filing of such report shall be given by the
clerk of the court to the parties in interest. Such report shall be subject to
exceptions to be heard before the court both upon the law and facts. The court
by its decree shall determine the value of the stock of the stockholders
entitled to payment therefor and shall direct the payment of such value,
together with interest, if any, as hereinafter provided, to the stockholders
entitled thereto by the surviving or resulting corporation. Upon payment of the
judgment by the surviving or resulting corporation, the clerk of the district
court shall surrender to the corporation the certificates of shares of stock
held by the clerk pursuant to subsection (g). The decree may be enforced as
other judgments of the district court may be enforced, whether such surviving or
resulting corporation be a corporation of this state or of any other state.

            (g) At the time of appointing the appraiser or appraisers, the court
shall require the stockholders who hold certificated shares and who demanded
payment for their shares to submit their certificates of stock to the clerk of
the court, to be held by the clerk pending the appraisal proceedings. If any
stockholder fails to comply with such direction, the court shall dismiss the
proceedings as to such stockholder.

            (h) The cost of any such appraisal, including a reasonable fee to
and the reasonable expenses of the appraiser, but exclusive of fees of counsel
or of experts retained by any party, shall be determined by the court and taxed
upon the parties to such appraisal or any of them as appears to be equitable,
except that the cost of giving the notice by publication and by registered or
certified mail hereinabove provided for shall be paid by the corporation. The
court, on application of any party in interest, shall determine the amount of
interest, if any, to be paid upon the value of the stock of the stockholders
entitled thereto.

            (i) Any stockholder who has demanded payment of the stockholder's
stock as herein provided shall not thereafter be entitled to vote such stock for
any purpose or be entitled to the payment of dividends or other distribution on
the stock, except dividends or other distributions payable to stockholders of
record at a date which is prior to the effective date of the merger or
consolidation, unless the appointment of an appraiser or appraisers shall not be
applied for within the time herein provided, or the proceeding be dismissed as
to such stockholder, or unless such stockholder with the written approval of the
corporation shall deliver to the corporation a written withdrawal of the
stockholder's objections to and an acceptance of the merger or consolidation, in
any of which cases the right of such stockholder to payment for the
stockholder's stock shall cease.

            (j) The shares of the surviving or resulting corporation into which
the shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

            (k) This section shall not apply to the shares of any class or
series of a class of stock, which, at the record date fixed to determine the
stockholders entitled to receive notice of and to vote at the meeting of
stockholders at which the agreement of merger or consolidation is to be acted
on, were either (1) registered on a national securities exchange or designated
as a national market system security on an interdealer quotation system by the
national association of securities dealers, inc., or (2) held of record by not
less than 2,000 stockholders, unless the articles of incorporation of the
corporation issuing such stock shall otherwise provide; nor shall this section
apply to any of the shares of stock of the constituent corporation surviving a
merger, if the merger did not require for its approval the vote of the
stockholders of the surviving corporation, as provided in subsection (f) of
K.S.A. 17-6701 and amendments thereto. This subsection shall not be applicable
to the holders of a class or series of a class of stock of a constituent
corporation if under the terms of a merger of consolidation pursuant to K.S.A.
17-6701 or 17-6702, and amendments thereto, such holders are required to accept
for such stock anything except (i) stock or stock and cash in lieu of fractional
shares of the corporation surviving or resulting from such merger or
consolidation, or (ii) stock or stock and cash in lieu of fractional shares of
any other corporation, which at the record date fixed to determine the
stockholders entitled to receive notice of and to vote at the meeting of
stockholders at which the agreement of merger or consolidation is to be acted
on, were either registered on a national securities exchange or held of record
by not less than 2,000 stockholders, or (iii) a combination of stock or stock
and cash in lieu of fractional shares as set forth in (i) and (ii) of this
subsection.

                            SECTIONS 3-202 AND 3-203


Section 3-202. Right to fair value of stock

            (a) General rule. -- Except as provided in subsection (c) of this
section, a stockholder of a Maryland corporation has the right to demand and
receive payment of the fair value of the stockholder's stock from the successor
if:

                  (1) The corporation consolidates or merges with another
corporation;

                  (2) The stockholder's stock is to be acquired in a share
exchange;

corporate action under Section 3-105 of this title;

                  (4) The corporation amends its charter in a way which alters
the contract rights, as expressly set forth in the charter, of any outstanding
stock and substantially adversely affects the stockholder's rights, unless the
right to do so is reserved by the charter of the corporation; or

                  (5) The transaction is governed by Section 3-602 of this title
or exempted by Section 3-603 (b) of this title.

            (b) Basis of fair value. --

                  (1) Fair value is determined as of the close of business:

                        (i) With respect to a merger under Section 3-106 of this
title of a 90 percent or more owned subsidiary into its parent, on the day
notice is given or waived under Section 3-106; or

                        (ii) With respect to any other transaction, on the day
the stockholders voted on the transaction objected to.

                  (2) Except as provided in paragraph (3) of this subsection,
fair value may not include any appreciation or depreciation which directly or
indirectly results from the transaction objected to or from its proposal.

                  (3) In any transaction governed by Section 3-602 of this title
or exempted by Section 3-603 (b) of this title, fair value shall be value
determined in accordance with the requirements of Section 3-603 (b) of this
title.

            (c) When right to fair value does not apply. -- Unless the
transaction is governed by Section 3-602 of this title or is exempted by Section
3-603 (b) of this title, a stockholder may not demand the fair value of his
stock and is bound by the terms of the transaction if:

                  (1) The stock is listed on a national securities exchange or
is designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc.:

                        (i) With respect to a merger under Section 3-106 of this
title of a 90 percent or more owned subsidiary into its parent, on the date
notice is given or waived under Section 3-106; or


<PAGE>   490
                        (ii) With respect to any other transaction, on the
record date for determining stockholders entitled to vote on the transaction
objected to;

                  (2) The stock is that of the successor in a merger, unless:

                        (i) The merger alters the contract rights of the stock
as expressly set forth in the charter, and the charter does not reserve the
right to do so; or

                        (ii) The stock is to be changed or converted in whole or
in part in the merger into something other than either stock in the successor or
cash, scrip, or other rights or interests arising out of provisions for the
treatment of fractional shares of stock in the successor; or

                  (3) The stock is that of an open-end investment company
registered with the Securities and Exchange Commission under the Investment
Company Act of 1940 and the value placed on the stock in the transaction is its
net asset value.

proposed transaction:

                        (i) With respect to a merger under Section 3-106 of this

for record, shall make a written demand on the successor for payment for his
stock, stating the number and class of shares for which he demands payment.

            (b) Failure to comply with section. -- A stockholder who fails to
comply with this section is bound by the terms of the consolidation, merger,

                        NEW YORK BUSINESS CORPORATION LAW
                              SECTIONS 628 AND 910


Section 623. Procedure to enforce shareholder's right to receive payment for
shares.

            (a) A shareholder intending to enforce his right under a section of
this chapter to receive payment for his shares if the proposed corporate action
referred to therein is taken shall file with the corporation, before the meeting
of shareholders at which the action is submitted to a vote, or at such meeting
but before the vote, written objection to the action. The objection shall
include a notice of his election to dissent, his name and residence address, the
number and classes of shares as to which he dissents a demand for payment of the
fair value of his shares if the action is taken. Such objection is not required
from any shareholder to whom the corporation did not give notice of such meeting
in accordance with this chapter or where the proposed action is authorized by
written consent of shareholders without a meeting.

            (b) Within ten days after the shareholders' authorization date,
which term as used in this section means the date on which the shareholders'
vote authorizing such action was taken, or the date on which such consent
without a meeting was obtained from the requisite shareholders, the corporation
shall give written notice of such authorization or consent by registered mail to
each shareholder who filed written objection or from whom written objection was
not required, excepting any shareholder who voted for or consented in writing to
the proposed action and who thereby is deemed to have elected not to enforce his
right to receive payment for his shares.

            (c) Within twenty days after the giving of notice to him, any
shareholder from whom written objection was not required and who elects to
dissent shall file with the corporation a written notice of such election,
stating his name and residence address, the number and classes of shares as to
which he dissents and a demand for payment of the fair value of his shares. Any
shareholder who elects to dissent from a merger under section 905 (Merger of
subsidiary corporation) or paragraph (c) of section 907 (Merger or consolidation
of domestic and foreign corporations) or from a share exchange under paragraph
(g) of section 913 (Share exchanges) shall file a written notice of such
election to dissent within twenty days after the giving to him of a copy of the
plan of merger or exchange or an outline of the material features thereof under
section 905 or 913.

            (d) A shareholder may not dissent as to less than all of the shares,
as to which he has a right to dissent, held by him of record, that he owns
beneficially. A nominee or fiduciary may not dissent on behalf of any beneficial
owner as to less than all of the shares of such owner, as to which such nominee
or fiduciary has a right to dissent, held of record by such nominee or
fiduciary.

            (e) Upon consummation of the corporate action, the shareholder shall
cease to have any of the rights of a shareholder except the right to be paid the
fair value of his shares and any other rights under this section. A notice of
selection may be withdrawn by the shareholder at any time prior to his
acceptance in writing of an offer made by the corporation, as provided in
paragraph (g), but in no case later than sixty days from the date of
consummation of the corporate action except that if the corporation fails to
make a timely offer, as provided in paragraph (g), the time for withdrawing a
notice of election shall be extended until sixty days from the date an offer is
made. Upon expiration of such time, withdrawal of a notice of election shall
require the written consent of the corporation. In order to be effective,
withdrawal of a notice of election must be accompanied by the return to the
corporation of any advance payment made to the shareholder as provided in
paragraph (g). If a notice of election is withdrawn, or the corporate action is
rescinded, or a court shall determine that the shareholder is not entitled to
receive payment for his shares, or the shareholder shall otherwise lose his
dissenters' rights, he shall not have the right to receive payment for his
shares and he shall be reinstated to all his rights as a shareholder as of the
consummation of the corporate action, including any intervening preemptive
rights and the right to payment of any intervening dividend or other
distribution or, if any such rights have expired or any such dividend or
distribution other than in cash has been completed, in lieu thereof, at the
election of the corporation, the fair value thereof in


<PAGE>   492
cash as determined by the board as of the time of such expiration or completion,
but without prejudice otherwise to any corporate proceedings that may have been
taken in the interim.

            (f) At the time of filing the notice of election to dissent or
within one month thereafter the shareholder of shares represented by
certificates shall submit the certificates representing his shares to the
corporation, or to its transfer agent, which shall forthwith note conspicuously
thereon that a notice of election has been filed and shall return the
certificates to the shareholder or other person who submitted them on his
behalf. Any shareholder of shares represented by certificates who fails to
submit his certificates for such notation as herein specified shall, at the
option of the corporation exercised by written notice to him within forty-five
days from the date of filing of such notice of election to dissent, lose his
dissenter's rights unless a court, for good cause shown, shall otherwise direct.
Upon transfer of a certificate bearing such notation, each new certificate
issued therefor shall bear a similar notation together with the name of the
original dissenting holder of the shares and a transferee shall acquire no
rights in the corporation except those which the original dissenting shareholder
had at the time of transfer.

            (g) Within fifteen days after the expiration of the period within
which shareholders may file their notices of election to dissent, or within
fifteen days after the proposed corporate action is consummated, whichever is
later (but in no case later than ninety days from the shareholders'
authorization date), the corporation or, in the case of a merger or
consolidation, the surviving or new corporation, shall make a written offer by
registered mail to each shareholder who has filed such notice of election to pay
for his shares at a specified price which the corporation considers to be their
fair value. Such offer shall be accompanied by a statement setting forth the
aggregate number of shares with respect to which notices of election to dissent
have been received and the aggregate number of holders of such shares. If the
corporate action has been consummated, such offer shall also be accompanied by
(1) advance payment to each such shareholder who has submitted the certificates
representing his shares to the corporation, as provided in paragraph (f), of an
amount equal to eighty percent of the amount of such offer, or (2) as to each
shareholder who has not yet submitted his certificates a statement that advance
payment to him of an amount equal to eighty percent of the amount of such offer
will be made by the corporation promptly upon submission of his certificates. If
the corporate action has not been consummated at the time of the making of the
offer, such advance payment or statement as to advance payment shall be sent to
each shareholder entitled thereto forthwith upon consummation of the corporate
action. Every advance payment or statement as to advance payment shall include
advice to the shareholder to the effect that acceptance of such payment does not
constitute a waiver of any dissenters' rights. If the corporate action has not
been consummated upon the expiration of the ninety day period after the
shareholders' authorization date, the offer may be conditioned upon the
consummation of such action. Such offer shall be made at the same price per
share to all dissenting shareholders of the same class, or if divided into
series, of the same series and shall be accompanied by a balance sheet of the
corporation whose shares the dissenting shareholder holds as of the latest
available date, which shall not be earlier than twelve months before the making
of such offer, and a profit and loss statement or statements for not less than a
twelve month period ended on the date of such balance sheet or, if the
corporation was not in existence throughout such twelve month period, for the
portion thereof during which it was in existence. Notwithstanding the foregoing,
the corporation shall not be required to furnish a balance sheet or profit and
loss statement or statements to any shareholder to whom such balance sheet or
profit and loss statement or statements were previously furnished, nor if in
connection with obtaining the shareholders' authorization for or consent to the
proposed corporate action the shareholders were furnished with a proxy or
information statement, which included financial statements, pursuant to
Regulation 14A or Regulation 14C of the United States Securities and Exchange
Commission. If within thirty days after the making of such offer, the
corporation making the offer and any shareholder agree upon the price to be paid
for his shares, payment therefor shall be made within sixty days after the
making of such offer or the consummation of the proposed corporate action,
whichever is later, upon the surrender of the certificates for any such shares
represented by certificates.

            (h) The following procedure shall apply if the corporation fails to
make such offer within such period of fifteen days, or if it makes the offer and
any dissenting shareholder or shareholders fail to agree with it within the
period of thirty days thereafter upon the price to be paid for their shares:

<PAGE>   493
                  (1) The corporation shall, within twenty days after the
expiration of whichever is applicable of the two periods last mentioned,
institute a special proceeding in the supreme court in the judicial district in
which the office of the corporation is located to determine the rights of
dissenting shareholders and to fix the fair value of their shares. If, in the
case of merger or consolidation, the surviving or new corporation is a foreign
corporation without an office in this state, such proceeding shall be brought in
the county where the office of the domestic corporation, whose shares are to be
valued, was located.

                  (2) If the corporation fails to institute such proceeding
within such period of twenty days, any dissenting shareholder may institute such
proceeding for the same purpose not later than thirty days after the expiration
of such twenty day period. If such proceeding is not instituted within such
thirty day period, all dissenters' rights shall be lost unless the supreme
court, for good cause shown, shall otherwise direct.

                  (3) All dissenting shareholders, excepting those who, as
provided in paragraph (g), have agreed with the corporation upon the price to be
paid for their shares, shall be made parties to such proceeding, which shall
have the effect of an action quasi in rem against their shares. The corporation
shall serve a copy of the petition in such proceeding upon each dissenting
shareholder who is a resident of this state in the manner provided by law for
the service of a summons, and upon each nonresident dissenting shareholder
either by registered mail and publication, or in such other manner as is
permitted by law. The jurisdiction of the court shall be plenary and exclusive.

                  (4) The court shall determine whether each dissenting
shareholder, as to whom the corporation requests the court to make such
determination, is entitled to receive payment for his shares. If the corporation
does not request any such determination or if the court finds that any
dissenting shareholder is so entitled, it shall proceed to fix the value of the
shares, which, for the purposes of this section, shall be the fair value as of
the close of business on the day prior to the shareholders' authorization date.
In fixing the fair value of the shares, the court shall consider the nature of
the transaction giving rise to the shareholder's right to receive payment for
shares and its effects on the corporation and its shareholders, the concepts and
methods then customary in the relevant securities and financial markets for
determining fair value of shares of a corporation engaging in a similar
transaction under comparable circumstances and all other relevant factors. The
court shall determine the fair value of the shares without a jury and without
referral to an appraiser or referee. Upon application by the corporation or by
any shareholder who is a party to the proceeding, the court may, in its
discretion, permit pretrial disclosure, including, but not limited to,
disclosure of any expert's reports relating to the fair value of the shares
whether or not intended for use at the trial in the proceeding and
notwithstanding subdivision (d) of section 3101 of the civil practice law and
rules.

                  (5) The final order in the proceeding shall be entered against
the corporation in favor of each dissenting shareholder who is a party to the
proceeding and is entitled thereto for the value of his shares so determined.

                  (6) The final order shall include an allowance for interest at
such rate as the court finds to be equitable, from the date the corporate action
was consummated to the date of payment. In determining the rate of interest, the
court shall consider all relevant factors, including the rate of interest which
the corporation would have had to pay to borrow money during the pendency of the
proceeding. If the court finds that the refusal of any shareholder to accept the
corporate offer of payment for his shares was arbitrary, vexatious or otherwise
not in good faith, no interest shall be allowed to him.

                  (7) Each party to such proceeding shall bear its own costs and
expenses, including the fees and expenses of its counsel and of any experts
employed by it. Notwithstanding the foregoing, the court may, in its discretion,
apportion and assess all or any part of the costs, expenses and fees incurred by
the corporation against any or all of the dissenting shareholders who are
parties to the proceeding, including any who have withdrawn their notices of
election as provided in paragraph (e), if the court finds that their refusal to
accept the corporate offer was arbitrary, vexatious or otherwise not in good
faith. The court may, in its discretion, apportion and assess all or any part of
the costs, expenses and fees incurred by any or all of the dissenting
shareholders who are parties to the

<PAGE>   494
proceeding against the corporation if the court finds any of the following: (A)
that the fair value of the shares as determined materially exceeds the amount
which the corporation offered to pay; (B) that no offer or required advance
payment was made by the corporation; (C) that the corporation failed to
institute the special proceeding within the period specified therefor; or (D)
that the action of the corporation in complying with its obligations as provided
in this section was arbitrary, vexatious or otherwise not in good faith. In
making any determination as provided in clause (A), the court may consider the
dollar amount or the percentage, or both, by which the fair value of the shares
as determined exceeds the corporate offer.

                  (8) Within sixty days after final determination of the
proceeding, the corporation shall pay to each dissenting shareholder the amount
found to be due him, upon surrender of the certificates for any such shares
represented by certificates.

            (i) Shares acquired by the corporation upon the payment of the
agreed value therefor or of the amount due under the final order, as provided in
this section, shall become treasury shares or be cancelled as provided in
section 515 (Reacquired shares), except that, in the case of a merger or
consolidation, they may be held and disposed of as the plan of merger or
consolidation may otherwise provide.

            (j) No payment shall be made to a dissenting shareholder under this
section at a time when the corporation is insolvent or when such payment would
make it insolvent. In such event, the dissenting shareholder shall, at his
option:

                  (1) Withdraw his notice of election, which shall in such event
be deemed withdrawn with the written consent of the corporation; or

                  (2) Retain his status as a claimant against the corporation
and, if it is liquidated, be subordinated to the rights of creditors of the
corporation, but have rights superior to the non-dissenting shareholders, and if
it is not liquidated, retain his right to be paid for his shares, which right
the corporation shall be obliged to satisfy when the restrictions of this
paragraph do not apply.

                  (3) The dissenting shareholder shall exercise such option
under subparagraph (1) or (2) by written notice filed with the corporation
within thirty days after the corporation has given him written notice that
payment for his shares cannot be made because of the restrictions of this
paragraph. If the dissenting shareholder fails to exercise such option as
provided, the corporation shall exercise the option by written notice given to
him within twenty days after the expiration of such period of thirty days.

            (k) The enforcement by a shareholder of his right to receive payment
for his shares in the manner provided herein shall exclude the enforcement by
such shareholder of any other right to which he might otherwise be entitled by
virtue of share ownership, except as provided in paragraph (e), and except that
this section shall not exclude the right of such shareholder to bring or
maintain an appropriate action to obtain relief on the ground that such
corporate action will be or is unlawful or fraudulent as to him.

            (l) Except as otherwise expressly provided in this section, any
notice to be given by a corporation to a shareholder under this section shall be
given in the manner provided in section 605 (Notice of meetings of
shareholders).

            (m) This section shall not apply to foreign corporations except as
provided in subparagraph (e)(2) of section 907 (Merger or consolidation of
domestic and foreign corporations).

consolidation, or sale, lease, exchange or other disposition of assets, or share
exchange

            (a) A shareholder of a domestic corporation shall, subject to and by

shares and the other rights and benefits provided by such section, in the
following cases:

                  (1) Any shareholder entitled to vote who does not assent to
the taking of an action specified in subparagraphs (A), (B) and (C).

                        (A) Any plan of merger or consolidation to which the

value of his shares shall not be available:

                              (i) To a shareholder of the parent corporation in
a merger authorized by section 905 (Merger of parent and subsidiary
corporations), or paragraph (c) of section 907 (Merger or consolidation of
domestic and foreign corporations); and (ii) To a shareholder of the surviving
corporation in a merger authorized by this article, other than a merger
specified in subparagraph (i), unless such merger effects one or more of the
changes specified in subparagraph (b) (6) of section 806 (Provisions as to
certain proceedings) in the rights of the shares held by such shareholder.

                        (B) Any sale, lease, exchange or other disposition of
all or substantially all of the assets of a corporation which requires
shareholder approval under section 909 (Sale, lease, exchange or other
disposition of assets) other than a transaction wholly for cash where the
shareholders' approval thereof is conditioned upon the dissolution of the
corporation and the distribution of substantially all of its net assets to the
shareholders in accordance with their respective interests within one year after
the date of such transaction.

                        (C) Any share exchange authorized by section 913 in
which the corporation is participating as a subject corporation; except that the
right to receive payment of the fair value of his shares shall not be available
to a shareholder whose shares have not been acquired in the exchange.

                  (2) Any shareholder of the subsidiary corporation in a merger
authorized by section 905 or paragraph (c) of section 907, or in a share
exchange authorized by paragraph (g) of section 913, who files with the
corporation a written notice of election to dissent as provided in paragraph (c)
of section 623.

                             ARTICLES 5.11 AND 5.12


Art. 5.11. Rights of Dissenting Shareholders in the Event of Certain Corporate
Actions

            A. Any shareholder of a domestic corporation shall have the right to
dissent from any of the following corporate actions:

                  (1) Any plan of merger to which the corporation is a party if
shareholder approval is required by Article 5.03 or 5.16 of this Act and the
shareholder holds shares of a class or series that was entitled to vote thereon
as a class or otherwise;

                  (2) Any sale, lease, exchange or other disposition (not
including any pledge, mortgage, deed of trust or trust indenture unless
otherwise provided in the articles of incorporation) of all, or substantially
all, the property and assets, with or without good will, of a corporation
requiring the special authorization of the shareholders as provided by this Act;

                  (3) Any plan of exchange pursuant to Article 5.02 of this Act
in which the shares of the corporation of the class or series held by the
shareholder are to be acquired.

            B. Notwithstanding the provisions of Section A of this Article, a
shareholder shall not have the right to dissent from any plan of merger in which
there is a single surviving or new domestic or foreign corporation, or from any
plan of exchange, if (1) the shares held by the shareholder are part of a class
shares [sic] of which are listed on a national securities exchange, or are held
of record by not less than 2,000 holders, on the record date fixed to determine
the shareholders entitled to vote on the plan of merger or the plan of exchange,
and (2) the shareholder is not required by the terms of the plan of merger or
the plan of exchange to accept for his shares any consideration other than (a)
shares of a corporation that, immediately after the effective time of the merger
or exchange, will be part of a class or series of shares of which are (i)
listed, or authorized for listing upon official notice of issuance, on a
national securities exchange, or (ii) held of record by not less than 2,000
holders, and (b) cash in lieu of fractional shares otherwise entitled to be
received.


Art 5.12. Procedure for Dissent by Shareholders as to Said Corporate Actions

            A. Any shareholder of any domestic corporation who has the right to
dissent from any of the corporate actions referred to in Article 5.11 of this
Act may exercise that right to dissent only by complying with the following
procedures:

                  (1)(a) With respect to proposed corporate action that is
submitted to a vote of shareholders at a meeting, the shareholder shall file
with the corporation, prior to the meeting, a written objection to the action,
setting out that the shareholder's right to dissent will be exercised if the
action is effective and giving the shareholder's address, to which notice
thereof shall be delivered or mailed in that event. If the action is effected
and the shareholder shall not have voted in favor of the action, the
corporation, in the case of action other than a merger, or the surviving or new
corporation (foreign or domestic) or other entity that is liable to discharge
the shareholder's right of dissent, in the case of a merger, shall, within ten
(10) days after the action is effected, deliver or mail to the shareholder
written notice that the action has been effected, and the shareholder may,
within ten (10) days from the delivery or mailing of the notice, make written
demand on the existing, surviving, or new corporation (foreign or domestic) or
other entity, as the case may be, for payment of the fair value of the
shareholder's shares. The fair value of the shares shall be the value thereof as
of the day immediately preceding the meeting, excluding any appreciation or
depreciation in anticipation of the proposed action. The


<PAGE>   497
demand shall state the number and class of the shares owned by the shareholder
and the fair value of the shares as estimated by the shareholder. Any
shareholder failing to make demand within the ten (10) day period shall be bound
by the action.

                  (b) With respect to proposed corporate action that is approved
pursuant to Section A of Article 9.10 of this Act, the corporation, in the case
of action other than a merger, and the surviving or new corporation (foreign or
domestic) or other entity that is liable to discharge the shareholder's right of
dissent, in the case of a merger, shall, within ten (10) days after the date the
action is effected, mail to each shareholder of record as of the effective date
of the action notice of the fact and date of the action and that the shareholder
may exercise the shareholder's right to dissent from the action. The notice
shall be accompanied by a copy of this Article and any articles or documents
filed by the corporation with the Secretary of State to effect the action. If
the shareholder shall not have consented to the taking of the action, the
shareholder may, within twenty (20) days after the mailing of the notice, make
written demand on the existing, surviving, or new corporation (foreign or
domestic) or other entity, as the case may be, for payment of the fair value of
the shareholder's shares. The fair value of the shares shall be the value
thereof as of the date the written consent authorizing the action was delivered
to the corporation pursuant to Section A of Article 9.10 of this Act, excluding
any appreciation or depreciation in anticipation of the action. The demand shall
state the number and class of shares owned by the dissenting shareholder and the
fair value of the shares as estimated by the shareholder. Any shareholder
failing to make demand within the twenty (20) day period shall be bound by the
action.

                  (2) Within twenty (20) days after receipt by the existing,
surviving, or new corporation (foreign or domestic) or other entity, as the case
may be, of a demand for payment made by a dissenting shareholder in accordance
with Subsection (1) of this Section, the corporation (foreign or domestic) or
other entity shall deliver or mail to the shareholder a written notice that
shall either set out that the corporation (foreign or domestic) or other entity
accepts the amount claimed in the demand and agrees to pay that amount within
ninety (90) days after the date on which the action was effected, and, in the
case of shares represented by certificates, upon the surrender of the
certificates duly endorsed, or shall contain an estimate by the corporation
(foreign or domestic) or other entity of the fair value of the shares, together
with an offer to pay the amount of that estimate within ninety (90) days after
the date on which the action was effected, upon receipt of notice within sixty
(60) days after that date from the shareholder that the shareholder agrees to
accept that amount and, in the case of shares represented by certificates, upon
the surrender of the certificates duly endorsed.

                  (3) If, within sixty (60) days after the date on which the
corporate action was effected, the value of the shares is agreed upon between
the shareholder and the existing, surviving, or new corporation (foreign or
domestic) or other entity, as the case may be, payment for the shares shall be
made within ninety (90) days after the date on which the action was effected
and, in the case of shares represented by certificates, upon surrender of the
certificates duly endorsed. Upon payment of the agreed value, the shareholder
shall cease to have any interest in the shares or in the corporation.

            B. If, within the period of sixty (60) days after the date on which
the corporate action was effected, the shareholder and the existing, surviving,
or new corporation (foreign or domestic) or other entity, as the case may be, do
not so agree, then the shareholder or the corporation (foreign or domestic) or
other entity may, within sixty (60) days after the expiration of the sixty (60)
day period, file a petition in any court of competent jurisdiction in the county
in which the principal office of the domestic corporation is located, asking for
a finding and determination of the fair value of the shareholder's shares. Upon
the filing of any such petition by the shareholder, service of a copy thereof
shall be made upon the corporation (foreign or domestic) or other entity, which
shall, within ten (10) days after service, file in the office of the clerk of
the court in which the petition was filed a list containing the names and
addresses of all shareholders of the domestic corporation who have demanded
payment for their shares and with whom agreements as to the value of their
shares have not been reached by the corporation (foreign or domestic) or other
entity. If the petition shall be filed by the corporation (foreign or domestic)
or other entity, the petition shall be accompanied by such a list. The clerk of
the court shall give notice of the time and place fixed for the hearing of the
petition by registered mail to the corporation (foreign or domestic) or other
entity and to the shareholders named on the list at the addresses


<PAGE>   498
therein stated. The forms of the notices by mail shall be approved by the court.
All shareholders thus notified and the corporation (foreign or domestic) or
other entity shall thereafter be bound by the final judgment of the court.

            C. After the hearing of the petition, the court shall determine the
shareholders who have complied with the provisions of this Article and have
become entitled to the valuation of and payment for their shares, and shall
appoint one or more qualified appraisers to determine that value. The appraisers
shall have power to examine any of the books and records of the corporation the
shares of which they are charged with the duty of valuing, and they shall make a
determination of the fair value of the shares upon such investigation as to them
may seem proper. The appraisers shall also afford a reasonable opportunity to
the parties interested to submit to them pertinent evidence as to the value of
the shares. The appraisers shall also have such power and authority as may be
conferred on Masters in Chancery by the Rules of Civil Procedure or by the order
of their appointment.

            D. The appraisers shall determine the fair value of the shares of
the shareholders adjudged by the court to be entitled to payment for their
shares and shall file their report of that value in the office of the clerk of
the court. Notice of the filing of the report shall be given by the clerk to the
parties in interest. The report shall be subject to exceptions to be heard
before the court both upon the law and the facts. The court shall by its
judgment determine the fair value of the shares of the shareholders entitled to
payment for their shares and shall direct the payment of that value by the
existing, surviving, or new corporation (foreign or domestic) or other entity,
together with interest thereon, beginning 91 days after the date on which the
applicable corporate action from which the shareholder elected to dissent was
effected to the date of such judgment, to the shareholders entitled to payment.
The judgment shall be payable to the holders of uncertificated shares
immediately but to the holders of shares represented by certificates only upon,
and simultaneously with, the surrender to the existing, surviving, or new
corporation (foreign or domestic) or other entity, as the case may be, of duly
endorsed certificates for those shares. Upon payment of the judgment, the
dissenting shareholders shall cease to have any interest in those shares or in
the corporation. The court shall allow the appraisers a reasonable fee as court
costs, and all court costs shall be allotted between the parties in the manner
that the court determines to be fair and equitable.

            E. Shares acquired by the existing, surviving, or new corporation
(foreign or domestic) or other entity, as the case may be, pursuant to the
payment of the agreed value of the shares or pursuant to payment of the judgment
entered for the value of the shares, as in this Article provided, shall, in the
case of a merger, be treated as provided in the plan of merger and, in all other
cases, may be held and disposed of by the corporation as in the case of other
treasury shares.

            F. The provisions of this Article shall not apply to a merger if, on
the date of the filing of the articles of merger, the surviving corporation is
the owner of all the outstanding shares of the other corporations, domestic or
foreign, that are parties to the merger.

            G. In the absence of fraud in the transaction, the remedy provided
by this Article to a shareholder objecting to any corporate action referred to
in Article 5.11 of this Act is the exclusive remedy for the recovery of the
value of his shares or money damages to the shareholder with respect to the
action. If the existing, surviving, or new corporation (foreign or domestic) or
other entity, as the case may be, complies with the requirements of this
Article, any shareholder who fails to comply with the requirements of this
Article shall not be entitled to bring suit for the recovery of the value of his
shares or money damages to the shareholder with respect to the action.


Art 5.13. Provisions Affecting Remedies of Dissenting Shareholders

            A. Any shareholder who has demanded payment for his shares in
accordance with either Article 5.12 or 5.16 of this Act shall not thereafter be
entitled to vote or exercise any other rights of a shareholder except the right
to receive payment for his shares pursuant to the provisions of those articles
and the


<PAGE>   499
right to maintain an appropriate action to obtain relief on the ground that the
corporate action would be or was fraudulent, and the respective shares for which
payment has been demanded shall not thereafter be considered outstanding for the
purposes of any subsequent vote of shareholders.

            B. Upon receiving a demand for payment from any dissenting
shareholder, the corporation shall make an appropriate notation thereof in its
shareholder records. Within twenty (20) days after demanding payment for his
shares in accordance with either Article 5.12 or 5.16 of this Act, each holder
of certificates representing shares so demanding payment shall submit such
certificates to the corporation for notation thereon that such demand has been
made. The failure of holders of certificated shares to do so shall, at the
option of the corporation, terminate such shareholder's rights under Articles
5.12 and 5.16 of this Act unless a court of competent jurisdiction for good and
sufficient cause shown shall otherwise direct. If uncertificated shares for
which payment has been demanded or shares represented by a certificate on which
notation has been so made shall be transferred, any new certificate issued
therefor shall bear similar notation together with the name of the original
dissenting holder of such shares and a transferee of such shares shall acquire
by such transfer no rights in the corporation other than those which the
original dissenting shareholder had after making demand for payment of the fair
value thereof.

            C. Any shareholder who has demanded payment for his shares in
accordance with either Article 5.12 or 5.16 of this Act may withdraw such demand
at any time before payment for his shares or before any petition has been filed
pursuant to Article 5.12 or 5.16 of this Act asking for a finding and
determination of the fair value of such shares, but no such demand may be
withdrawn after such payment has been made or, unless the corporation shall
consent thereto, after any such petition has been filed. If, however, such
demand shall be withdrawn as hereinbefore provided, or if pursuant to Section B
of this Article the corporation shall terminate the shareholder's rights under
Article 5.12 or 5.16 of this Act, as the case may be, or if no petition asking
for a finding and determination of fair value of such shares by a court shall
have been filed within the time provided in Article 5.12 or 5.16 of this Act, as
the case may be, or if after the hearing of a petition filed pursuant to Article
5.12 or 5.16, the court shall determine that such shareholder is not entitled to
the relief provided by those articles, then, in any such case, such shareholder
and all persons claiming under him shall be conclusively presumed to have
approved and ratified the corporate action from which he dissented and shall be
bound thereby, the right of such shareholder to be paid the fair value of his
shares shall cease, and his status as a shareholder shall be restored without
prejudice to any corporate proceedings which may have been taken during the
interim, and such shareholder shall be entitled to receive any dividends or
other distributions made to shareholders in the interim.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Company's Amended Bylaws provide that the Company shall, to the
fullest extent permitted by Section 145 of the DGCL, as amended from time to
time, indemnify all persons whom it may indemnify pursuant thereto.

         Section 145 of the DGCL permits a corporation, under specified
circumstances, to indemnify its directors, officers, employees or agents against
expenses (including attorney's fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by them in connection with any
action, suit or proceeding brought by third parties by reason of the fact that
they were or are directors, officers, employees or agents of the corporation, if
such directors, officers, employees or agents acted in good faith and in a
manner they reasonably believed to be in or not opposed to the best interests of
the corporation and, with respect to any criminal action or proceeding, had no
reason to believe their conduct was unlawful. In a derivative action, i.e., one
by or in the right of the corporation, indemnification may be made only for
expenses actually and reasonably incurred by directors, officers, employees or
agents in connection with the defense or settlement of an action or suit, and
only with respect to a matter as to which they shall have acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification shall be made if
such person shall have been adjudged liable to the corporation, unless and only
to the extent that the court in which the action or suit was brought shall
determine upon application that the defendant directors, officers, employees or
agents are fairly and reasonably entitled to indemnity for such expenses despite
such adjudication of liability.

         Article VI of the Company's Restated Certificate of Incorporation, as
amended, provides that the Company's directors will not be personally liable to
the Company or its stockholders for monetary damages resulting from breaches of
their fiduciary duty as directors except for liability (a) for any breach of the
duty of loyalty to the Company or its stockholders, (b) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, (c) under Section 174 of the DGCL or (d) for any transaction from which
the director derived an improper personal benefit.

         Reference is made to Article VIII of the Company's Amended and Restated
Bylaws filed as an Exhibit to this Registration Statement, which provides for
indemnification of directors and officers.

         In _____________, 1997, the Company entered into an indemnification
agreement with certain of its directors and director nominees, pursuant to which
the Company agreed to indemnify such persons for losses arising out of any
untrue statement or alleged untrue statement of a material fact contained in the
Registration Statement of which this Prospectus forms a part.

ITEM 22. UNDERTAKINGS.

         (1) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

         (2) The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

         (3) The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         (4) The undersigned Registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Item 4, 10(b), 11, or 13 of Form S-4, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

         (5) The undersigned Registrant hereby undertakes to supply by means of
a post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

         Section 2.9      Exchange of Certificates Representing Shares of the
Company Common Stock.

                 (a)      At or after the Effective Time and at the Closing (i)
the Stockholders, as holders of a certificate or certificates representing
shares of each Company's Common Stock, shall upon surrender of each certificate
or certificates (or completion of appropriate affidavit of lost certificate and
indemnity) receive such allocation of Merger Consideration as determined in
accordance with the provisions of Exhibit B attached hereto; and (ii) until
each certificate or certificates representing Company Common Stock have been
surrendered by the Stockholders, the certificates for Company Common Stock
shall, for all purposes, represent solely the right to receive Merger
Consideration as determined in accordance with the provisions of Exhibit B
attached hereto and Section 2.10 hereof, if applicable.  At the Effective Time,
each share of Company Common Stock converted into Merger Consideration shall by
virtue of the Merger and without any action on the part of the holders thereof,
cease to be outstanding, be cancelled and returned and all shares of APP Common
Stock issuable to the Stockholders in the Merger as part of the Merger

the certificates representing Company Common Stock owned by him, her or it,
duly endorsed in blank by the Stockholder, or accompanied by duly executed
stock powers in blank, and with all necessary transfer tax and other revenue
stamps, acquired at the Stockholder's expense, affixed and cancelled.  Each
Stockholder agrees to cure any deficiencies with respect to the endorsement of
the certificates or other documents of conveyance with respect to such Company
Common Stock or with respect to the stock powers accompanying any Company
Common Stock.  Upon such delivery (or completion of appropriate affidavit of
lost certificate and indemnity), each Stockholder shall receive in exchange
therefor the Merger Consideration pursuant to Exhibit B and Section 2.10
hereof, if applicable.

         Section 2.10     Fractional Shares.  Notwithstanding any other
provision herein, no fractional shares of APP Common Stock will be issued and
any Stockholder otherwise entitled to receive a fractional share of APP Common
Stock as part of the Merger Consideration hereunder shall receive a cash
payment in lieu thereof reflecting such Stockholder's proportionate interest in
a share of APP Common Stock multiplied by the Initial Public Offering Price.

                                  ARTICLE III

                 Representations and Warranties of the Company

         As an inducement to APP and APP Sub to enter into this Agreement and
to consummate the Merger and except as set forth in the Disclosure Schedules
attached hereto and incorporated herein by this reference, each Company and
Company Subsidiary individually represents and warrants to APP and APP Sub both
as of the date hereof and as of the Effective Time as follows:

         Section 3.1      Organization and Good Standing; Qualification.  The
Company is a corporation duly organized, validly existing and in good standing
under the laws of its state of incorporation, with all requisite corporate
power and authority to own, operate and lease its assets and properties and to
carry on its business as currently conducted.  The Company and each Company
Subsidiary is in good standing in each jurisdiction where the character of the
property owned or leased by it or the nature of its activities makes such
qualification necessary, except where such failure to be so qualified or in
good standing would not have a Material Adverse Effect on the Company.  Copies
of the articles or certificates of incorporation and all amendments thereto of
the Company and each Company Subsidiary and the bylaws of the Company and each
Company Subsidiary, as amended, and copies of the corporate minutes of the
Company, all of which have been or will be made available to APP for review,
are true and complete as in effect on the date of this Agreement, and in the
case of the corporate minutes, accurately reflect all material proceedings of
the Stockholders and directors of the Company (and all committees thereof).
The stock record books of the Company, which have been or will be made
available to APP for review, contain true, complete and





                                       8
<PAGE>   16
accurate records of the stock ownership of record of the Company and the
transfer record of the shares of its capital stock.

         Section 3.2      Authorization and Validity.  The Company has all
requisite corporate power to enter into this Agreement and all other agreements
entered into in connection with the transactions contemplated hereby and to
consummate the transactions contemplated hereby.  The execution, delivery and,
subject to approval of this Agreement and the Merger by the Stockholders,
performance by the Company of this Agreement and the agreements contemplated
herein, and the consummation by the Company of the transactions contemplated
hereby and thereby are within the Company's respective corporate powers and
have been duly authorized by all necessary action on the part of the Company's
Board of Directors.  Subject to the approval of this Agreement and the Merger
by the Stockholders, this Agreement has been duly executed by the Company, and
this Agreement and all other agreements and obligations entered into and
undertaken in connection with the transactions contemplated hereby to which the
Company is a party constitute, or upon execution will constitute, valid and
binding agreements of the Company, enforceable against it in accordance with
their respective terms, except as enforceability may be limited by bankruptcy
or other laws affecting the enforcement of creditors' rights generally, or by
general equity principles, or by public policy.

         Section 3.3      Governmental Authorization.  Other than complying
with the provisions of the applicable state corporate laws regarding the
approval of the Merger and the filing of the Certificates of Merger (as
contemplated by Section 2.3) and any other required documents related to the
Merger, and other than consents, filings or notifications required to be made
or obtained solely by APP or APP Sub (including, without limitation, in
connection with the Initial Public Offering, Form S-4 or any Hart-Scott-Rodino
filing to be made by APP, if any), the execution, delivery and performance by
the Company of this Agreement and the agreements provided for herein, and the
consummation of the transactions contemplated hereby and thereby by the Company
require no action by or in respect of, or filing with, any governmental body,
agency, official or authority.

         Section 3.4      Capitalization.  The authorized capital stock and
shares issued and outstanding are listed in the Disclosure Schedules.  The
Stockholders collectively are and will be immediately prior to the Effective
Time the record and beneficial owners of all the issued and outstanding Company
Common Stock, free and clear of all Encumbrances, in the respective amounts set
forth in the Disclosure Schedules.  Each outstanding share of Company Common
Stock has been legally and validly issued and is fully paid and nonassessable,
and was issued pursuant to a valid exemption from registration under (i) the
Securities Act of 1933, as amended, and (ii) all applicable state securities
laws.  No shares of Company Common Stock are owned by the Company in treasury.
No shares of Company Common Stock have been issued or disposed of in violation
of any preemptive rights, rights of first refusal or similar rights of any of
the Stockholders.  Other than Company Common Stock, the Company has no
securities, bonds, debentures, notes or other obligations the holders of which
have the right to vote (or are convertible into or exercisable for securities
having the right to vote) with the Stockholders on any matter.

         Section 3.5      Transactions in Capital Stock.  There exist no
Company Rights.  The Company has no obligation (contingent or otherwise) to
purchase, redeem or otherwise acquire any of its equity securities or any
interests therein or to pay any dividend or make any distribution in respect
thereof.  Neither the equity structure of the Company nor the relative
ownership of shares among any of its Stockholders has been altered or changed
in contemplation of the Merger within the two (2) years preceding the date of
this Agreement.

         Section 3.6      Continuity of Business Enterprise.  There has not
been any sale, distribution or spin-off of significant assets of the Company or
any of its Affiliates other than in the ordinary course of business within the
(2) two years preceding the date of this Agreement.

         Section 3.7      Subsidiaries and Investments.  The Company does not
own, directly or indirectly, any capital stock or other equity, ownership or
proprietary interest in any corporation, partnership, association, trust, joint
venture or other entity (each a "Company Subsidiary").

         Section 3.8      Absence of Conflicting Agreements or Required
Consents.  Subject to approval of this Agreement and the Merger by the
Stockholders of the Company, the execution, delivery and performance by the
Company of this Agreement and any other documents contemplated hereby (with or
without the giving of notice, the lapse of time, or both): (i) do not require
the consent of any governmental or regulatory body or authority or any other
third party except for such consents, for which the failure to obtain would not
result in a Material Adverse Effect on the Company; (ii) will not conflict with
or result in a violation of any provision of the Company's articles or
certificate of incorporation or bylaws, (iii) will not conflict with, result in
a violation of, or constitute a default under any law, rule, ordinance,
regulation or any ruling, decree, determination, award, judgment, order or
injunction of any court or governmental instrumentality which is applicable to
the Company or by which the Company or its properties are subject or bound;
(iv) will not conflict with, constitute grounds for termination of, result in a
breach of, constitute a default under, require any notice under, or accelerate
or modify, or permit any person to accelerate or modify, any performance
required by the terms of any agreement, instrument, license or permit, to which
the Company is a party or by which the Company or any of its properties are
subject or bound except for such conflict, termination, breach or default, the
occurrence of which would not result in a Material Adverse Effect on the
Company; and (v) except as contemplated by this Agreement, will not create any
Encumbrance or restriction upon the Company Common Stock or any of the assets
or properties of the Company.

         Section 3.9      Intentionally omitted.

         Section 3.10     Absence of Changes.  Except as permitted or

Adverse Effect on the Company;

                 (b)      paid, discharged or satisfied any material liability,

                 (h)      mortgaged, pledged, subjected or agreed to subject,
any of its assets, tangible or intangible, to any claim or Encumbrance, except

action described in this Section 3.10.

         Section 3.11     No Undisclosed Liabilities.  To the best of its
knowledge, the Company does not have any liabilities or obligations of any
nature, whether accrued, absolute, contingent or otherwise, asserted or
unasserted except for liabilities or obligations reflected or reserved against
in the Company's Current Balance Sheet.

         Section 3.12     Litigation and Claims.  There are no claims,
lawsuits, actions, arbitrations, administrative or other proceedings,
governmental investigations or inquiries pending or, to the knowledge of the
Company, threatened against, or affecting the Company, any Company Subsidiary,
any Stockholder, the Physician Employees or any other licensed professional or
other individual affiliated with the Company affecting or that would reasonably
be likely to affect the Company Common Stock or the operations, business
condition, (financial or otherwise), or results of operations of the Company
which (i) if successful, may, individually or in the aggregate, have a Material
Adverse Effect on the Company or (ii) could adversely affect the ability of the
Company or any Company Subsidiary to effect the transactions contemplated
hereby, and to the knowledge of the Company there is no basis for any such
action or any state of facts or occurrence of any event which would reasonably
be likely to give rise to the foregoing.  There are no unsatisfied judgments
against the Company or any Company Subsidiary or any licensed professional or
other individual affiliated with the Company or any Company Subsidiary relating
to services provided on behalf of the Company or any Company Subsidiary or any
consent decrees to which any of the foregoing is subject.  Each of the matters,
if any, set forth in this Section 3.12 is fully covered by policies of
insurance of the Company or any Company Subsidiary as in effect on the date
hereof.

         Section 3.13     No Violation of Law.  Neither the Company nor any
Company Subsidiary has been, nor shall be as of the Effective Time (by virtue
of any action, omission to act, contract to which it is a party or any
occurrence or state of facts whatsoever), in violation of any applicable local,
state or federal law, ordinance, regulation, order, injunction or decree, or
any other requirement of any governmental body, agency, authority or court
binding on it, or relating to its properties, assets or business or its
advertising, sales or pricing practices, except for violations which,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on the Company.

         Section 3.14     Lease Agreements.  The Disclosure Schedules contain a
true, accurate and complete list of all the lease agreements and license
agreements to which the Company or any Company Subsidiary is a party and
pursuant to which the Company or any Company Subsidiary leases (whether as
lessor or lessee) or licenses (whether as licensor or licensee) any real or
personal property related to the





                                       11
<PAGE>   19
operation of its business and which requires payments in excess of $12,000 per
year (the "Lease Agreements").  The Company has delivered to APP true and
complete copies of all of the Lease Agreements.  Each Lease Agreement is valid,
effective and in full force in accordance with its terms, and there is not
under any such lease (i) any existing or claimed material default by the
Company or any Company Subsidiary (as applicable) or event of material default
or event which with notice or lapse of time, or both, would constitute a
material default by the Company or any Company Subsidiary (as applicable) and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Company, or, (ii) to the knowledge of the Company, any existing
material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party.  To the knowledge of the
Company, there is no pending or threatened reassessment of any property covered
by the Lease Agreements.  The Company or any Company Subsidiary will use
reasonable good faith efforts to obtain, prior to the Effective Time, the
consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver
to APP or APP Sub in writing such consents as are necessary to effect a valid
and binding transfer or assignment of the Company's or any Company Subsidiary's
rights thereunder.  The Company has a good, clear, valid and enforceable
leasehold interest under each of the Lease Agreements.  The Lease Agreements
comply with the exceptions to ownership interests and compensation arrangements
set out in 42 U.S.C. Section  1395nn, 42 C.F.R. Section 1001.952, and any
similar applicable state law safe harbor or other exemption provisions.

         Section 3.15     Real and Personal Property.

                 (a)      Neither the Company nor any Company Subsidiary owns
any interest (other than the Lease Agreements) in real property.

                 (b)      The Company and any Company Subsidiary (i) has good
title to all of its properties and assets (real, personal and mixed, tangible
and intangible) and any rights or interests therein which it purports to own
including, without limitation, all the property and assets reflected in the
Company Current Financial Statements; and (ii) owns such rights, interests,
assets and property free and clear of all Encumbrances, title defects or
objections (except for taxes not yet due and payable).  The personal property
presently used in connection with the operation of the business of the Company
and the Company Subsidiaries constitutes the necessary personal property assets
to continue operation of the Company and any Company Subsidiary.

         Section 3.16     Indebtedness for Borrowed Money.  Except for trade
payables incurred in the ordinary course of business, the Company does not have
any direct or indirect indebtedness for borrowed money, including indebtedness
by way of lease-purchase arrangements or guarantees, and is not obligated in
any manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

         Section 3.17     Contracts and Commitments.

                 (a)      The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies,
of each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate
(other than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health
maintenance organization, other managed care organization or other third-party
provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of
obligations of third parties requiring the Company to make, or setting forth
conditions under which the





                                       12
<PAGE>   20
Company would be required to make, aggregate future payments in excess of
$10,000 in any fiscal year or $25,000 in the aggregate, (iii) all agreements
for capital improvements or acquisitions involving an amount of $75,000 in any
fiscal year or $75,000 in the aggregate, (iv) all agreements containing a
covenant limiting the freedom of the Company (or any provider employee of the
Company) to compete in any line of business with any person or entity or in any
geographic area or (v) all written contracts and commitments providing for
future payments by the Company in excess of $10,000 in any fiscal year or
$25,000 in the aggregate and that are not cancelable by providing notice of
sixty (60) days or less.  All such contracts, agreements or other instruments
are in full force and effect, there has been no threatened cancellation
thereof, there are no outstanding disputes thereunder, each is with unrelated
third parties and was entered into on an arms-length basis and, assuming the
receipt of the appropriate consents, all will continue to be binding in
accordance with their terms after consummation of the transaction contemplated
herein; there are no contracts, agreements or other instruments to which the
Company is a party or is bound (other than physician employment contracts and
insurance policies) which could either singularly or in the aggregate have a
Material Adverse Effect on the value to APP or APP Sub of the assets and
properties to be acquired by APP or APP Sub from the Company, or which could
inhibit or prevent the Company from transferring to or vesting in APP or APP
Sub good and sufficient title to the assets and properties to be acquired by
APP or APP Sub and the Surviving Corporation except where the failure to
transfer would not have a Material Adverse Effect on APP or APP Sub.  In every
instance where consent is necessary, the Company shall, on or before the
Closing Date, use reasonable good faith efforts to obtain and deliver to APP or
APP Sub in writing, effective as of the Closing Date, such consents as are
necessary to enable the Surviving Corporation to enjoy all of the rights now
enjoyed by the Company under such contracts.  Any and all such consents shall
be in a form reasonably acceptable to APP and shall contain an acknowledgment
by the consenting party that the Company has fully complied with and is not in
default under any provision of the particular contract or agreement.
Notwithstanding the foregoing, the Company shall not transfer to APP or APP Sub
any contracts or agreements relating to the provision of professional medical
services or other such agreements and contracts that APP consents to in writing
to be transferred to NewCo in the Spin-off Transaction.  No contract with a
health care provider or Payor has been materially amended or terminated within
the last twelve (12) months.

                 (b)      The Company (i) has not received notice of any plan
or intention of any other party to exercise any right to cancel or terminate
any contract, agreement or instrument required to be disclosed pursuant to
Section 3.17(a), and to the knowledge of the Company there are no fact(s) that
would justify the exercise of such a right; and (ii) does not currently
contemplate, or have reason to believe any other Person currently contemplates,
any amendment or change to any such contract, agreement or instrument.

         Section 3.18     Employee Matters.  The Company is not currently a
party to any employment contract (except for oral employment agreements which
are terminable at will), consulting or collective bargaining contracts,
deferred compensation, pension plan (as defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974, as amended, and all rules and
regulations from time to time promulgated thereunder ("ERISA")), profit
sharing, bonus, stock option, stock purchase or other nonqualified benefit or
compensation commitments, benefit plans, arrangements or plans (whether written
or oral), including all welfare plans (as defined in Section 3(1) of ERISA) of
or pertaining to the Company and any of its present or former employees, or any
predecessors in interest.  As of April 30, 1997, the Company employed the
number of part-time and full-time employees listed in the Disclosure Schedules.
The Disclosure Schedules list each employee of, or consultant to, the Company
who received combined salary, benefits (other than those offered generally to
all other employees) and bonuses for 1996 in excess of $50,000 or who is
expected to receive combined salary, benefits (other than those offered
generally to all other employees) and bonuses in 1997 in excess of $50,000.
The Company is not delinquent in payment to any of its employees or Physician
Employees for wages, salaries, bonuses or other direct compensation for any
services performed for it to the date hereof or amounts required to be
reimbursed to such employees.  Upon termination of employment of any employee
or Physician Employee, no severance or other payments will become due and the
Company has no policy, past practice or plan of paying severance on termination
of employment.

Company, no basis for any such audit exists which, if conducted would result in
a Material Adverse Effect on the Company;

                 (d)      The Company is in material compliance with the
Immigration Reform and Control Act of 1986, as amended, and all applicable
regulations promulgated thereunder; and

                 (e)      To the knowledge of the Company, there are no

determined on an ongoing basis as of the date hereof.  With respect to each
Employee Benefit Plan described in Section 501(c)(9) of the Code, the assets of
each such plan are at least equal in value to the present value of accrued
benefits, based upon the most recent actuarial valuation as of a date no more
than ninety (90) days prior to the date hereof.  The Disclosure Schedules

to determine the present value of accrued benefits under all Employee Benefit
Plans subject to actuarial assumptions.

                 (h)      Excise Taxes.  Neither the Company nor any member of

                 (j)      PBGC.  No facts or circumstances are known to the
Company that would result in the imposition of liability against APP, APP Sub
or any of its Affiliates by the Pension Benefit Guaranty Corporation ("PBGC")
as a result of any act or omission by the Company or any member of a Controlled
Group.  No reportable event (within the meaning of Section 4043 of ERISA) for
which the notice requirement has not been waived has occurred with respect to
any Employee Benefit Plan subject to the requirements of Title IV of ERISA.

                 (k)      Retirees.  The Company has no obligation or
commitment to provide medical, dental or life insurance benefits to or on
behalf of any of its employees who may retire or any of its former employees

the business of the Company or any Company Subsidiary (the "Insurance
Policies").  All of the Insurance Policies are valid, outstanding and
enforceable policies, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies and all premiums with respect thereto which
are due and payable are currently paid.  All Insurance Policies currently

complete and correct copies of all Insurance Policies have been provided to
APP.  Neither the Company nor any Company Subsidiary nor any officer or
director thereof has received any notice or other written communication from
any issuer of any Current Policy cancelling such policy, materially increasing

been denied by an insurance agency or carrier.  The Disclosure Schedules also
set forth a list of all claims under any Insurance Policy in excess of $10,000
per occurrence filed by the Company or any Company Subsidiary during the

expected to account for more than 5% of the revenues of the Company for the
fiscal year to end December 31, 1997, and (ii) a single line item listing for
all private-pay patients in the aggregate of the Company.  The Company has

the Company's business and conform to generally accepted standards in the
industry of which the Company is a part.  The value of the inventories
reflected on the Company Current Balance Sheet contained in the Company
Financial Statements are net of adequate reserves for damaged, excess, and
unusable items.  Purchase commitments of the Company for inventory are not
materially in excess of normal requirements, and none of such purchase
commitments are at prices in excess of prevailing market prices at the time of

the laws of the state of Delaware, with all requisite corporate power and
authority to own, operate and lease its assets and properties and to carry on
its business as currently conducted.  APP is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the

change in any material respect the accounting methods or practices followed by
the Company (including any material change in any assumption underlying, or any

consistent with past practice, change any tax accounting method, enter into any
closing agreement, settle any tax claim or assessment or consent to any tax
claim or assessment or any waiver of the statute of limitations for any such

prior to Closing, which schedule will be subject to the approval of APP, which
approval shall not be unreasonably withheld) which by law either cannot be
acquired or cannot be used by APP because they relate to the practice of
medicine or radiology, and shall contribute to NewCo such other consideration
and assets of the Company as may be required under applicable law, in exchange
for the issuance by NewCo of shares of NewCo Common Stock, such shares being
all of the issued and outstanding shares of NewCo Common Stock.  The Company

APP Sub as each Company and their representatives may reasonably request, all
for the sole purpose of permitting each Company to become familiar with the

under Section 401(a)(4) of the Code) to the benefits provided under the

determination from the IRS that NewCo is not a member of an affiliated service
group (as defined in Section 414(m) of the Code) or a recipient organization of

inclusion in the Registration Statements, by exhibit or otherwise and (ii) in
the case of APP or APP Sub, will, at the time the Registration Statements and
each amendment and supplement thereto, if any, becomes effective under the
Securities Act, none of them contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.  Each Company shall be entitled to review the
Registration Statements and each of the amendments thereto, if any, prior to
the time each becomes effective under the Securities Act.  Each Company shall
have no responsibility for information contained in the Registration Statements
except for information provided by each Company specifically for inclusion
therein.  Each Company's review of the Registration Statements shall not
diminish or otherwise affect the representations, covenants and warranties of
APP and APP Sub contained in this Agreement.

         (c)     Each Company shall, upon request, furnish APP with all
information concerning itself, its subsidiaries, directors, officers, partners,
Stockholders and NewCo, and such other matters as may be reasonably requested

until the Closing to supplement or amend promptly the Disclosure Schedules with
respect to any matter that would have been or would be required to be set forth
or described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on each Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Disclosure Schedule that constitutes or reflects a Material Adverse Effect on
APP may be made unless each Company consents to such amendment or supplement.
For purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 10.1 and 11.1 have
been fulfilled, the Disclosure Schedules hereto shall be deemed to be the
Disclosure Schedules as amended or supplemented pursuant to this Section

Schedule pursuant to this Section 9.2 and APP does not consent to such
amendment or supplement, or APP seeks to amend or supplement a Disclosure
Schedule pursuant to this Section 9.2, and each Company does not consent, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
15.1(a) hereof.

         Section 9.3      Actions Contrary to Stated Intent.  No party hereto
will knowingly, either before or after the Merger, take any action that would
prevent the Merger from qualifying as a tax-free exchange within the meaning of
Section 351 of the Code.

solely responsible for their own fees and expenses with respect to the
transactions contemplated herein including, without limitation, the fees
charged by attorneys, accountants and financial advisors retained by such
parties.  The fees and expenses incurred by each Company and NewCo in
connection with the Merger shall be paid by each Company in full immediately
prior to the Closing and such expenses shall be the sole responsibility of the
Stockholders following the Closing Date and not APP.

         Section 9.6      Patient Confidentiality.  APP and APP Sub shall agree
to keep all records and information regarding the patients of each Company and
NewCo confidential in accordance with all applicable laws.

                              Post Closing Matters

         Section 13.1     Further Instruments of Transfer.  Following the
Closing, at the request of APP or the Surviving Corporation and at APP's sole
cost and expense, the Stockholders and each Company shall deliver any further
instruments of transfer and take all reasonable action as may be necessary or

the Closing, at the request of NewCo and at NewCo's sole cost and expense, APP
or the Surviving Corporation shall deliver any further instruments of transfer
and take all reasonable action as may be necessary and appropriate to carry out
the purpose and intent of this Agreement.

         Section 13.2     Merger Tax Covenant.

         (a)     The parties intend that the Merger will qualify as a tax-free
transaction under Section 351 of the Code in which each Company will not
recognize gain or loss, and pursuant to which any gain recognized by a
Stockholder as a result of the Merger will not exceed the amount of any cash
received by a Stockholder in the Merger (a "Reorganization").

         (b)     Both prior to and after the Effective Time, all books and
records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Merger being treated as a Reorganization.
These obligations are excused as to a party required to maintain the books or
file a Tax Return if such party has provided to the other parties a written
opinion of competent tax counsel to the effect that there is not substantial
authority, within the meaning of Section 6662(d)(2)(B)(i) of the Code, to
report the Merger as a Reorganization and such opinion either is furnished
prior to the Effective Time or is based on facts or events not known at the
Effective Time.  Each party shall provide to each other party such tax
information, reports, returns, or schedules as may be reasonably required to
assist such party in accounting for and reporting the Merger as a
Reorganization.

         (c)     The parties agree that no Stockholder shall be liable for any
taxes incurred by each Company and for which APP has successor liability
therefor which arise solely as a result of the Merger or the consummation of
the transactions contemplated hereby; provided that the foregoing shall not
limit or otherwise be deemed a waiver of any right of indemnification under
Section 14.1 for a breach of any representation, warranty or covenant of each
Company or any Stockholder.

         Section 13.3     Current Public Information.  APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of each Company to meet the requirements of
Rule 145(d) under the Securities Act.

                                    Remedies

         Section 14.1     Indemnification by each Company.  Subject to the
terms and conditions of this Article XIV, each Company agrees to indemnify,
defend and hold APP and the Surviving Corporation and their respective
directors, officers, stockholders, employees, agents, attorneys, consultants
and Affiliates harmless from and against all losses, claims, obligations,
demands, assessments, penalties, liabilities, costs, damages, reasonable
attorneys' fees and expenses (including, without limitation, all costs of
experts and all costs incidental to or in connection with any appellate
process) (collectively, "Damages") asserted against or incurred by such
individuals and/or entities arising out of or resulting from:

                 (a)      a breach by the Company of any representation or
warranty (without giving effect to any Material Adverse Effect qualifier
contained as part of any such representation or warranty) or covenant of the
Company contained in this Agreement or in any Disclosure Schedule or
certificate delivered thereunder;

                 (b)      any violation (or alleged violation) by the Company
and/or any of its past or present directors, officers, partners, stockholders,
employees (including, without limitation, any Physician Employee), agents,
attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons
in which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                 (c)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any (i) untrue
statement of material fact in any Registration Statement or any prospectus
forming or part thereof, or any amendment thereof or supplement thereto
relating to the Company (including any Company Subsidiary) or NewCo required to
be stated therein or (ii) failure to state information necessary to make the
statements therein not misleading, which untrue statement or failure to state
information arises or results solely from information provided in writing to
APP or its counsel by the Company or any Stockholder or their agents
specifically for inclusion in any such Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto.

         Section 14.2     Indemnification by APP and APP Sub.  Subject to the
terms and conditions of this Article XIV, APP and APP Sub jointly and severally
hereby agree to indemnify, defend and hold the Stockholders, the Company and
NewCo and their respective directors, officers, stockholders, employees,
agents, attorneys, consultants and Affiliates harmless from and against all
Damages asserted against or incurred by such individuals and/or entities
arising out of or resulting from:

                 (a)      a breach by APP or APP Sub of any representation or
warranty (without giving effect to any Material Adverse Effect qualifier
contained as part of any such representation or warranty) or covenant of APP or
APP Sub contained in this Agreement or in any schedule or certificate delivered
hereunder; and

                 (b)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any untrue statements
of material fact in any Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or required to be
stated therein or failure to state information necessary to make the statements
therein not misleading (except for any liability based upon any actual or
alleged untrue statement of material fact or an omission to state a material
fact relating to NewCo, the Company or any Stockholder to the extent derived
from any information provided in writing by the Company or a Company Subsidiary
or any of their agents contained in the representations and





                                       40
<PAGE>   48
warranties set forth in this Agreement or any certificate, exhibit, schedule or
instrument required to be delivered under this Agreement.)

                 Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
of any of the parties hereto of liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

         Section 14.3     Conditions of Indemnification.  All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                 (a)      Any party claiming indemnification under the
Agreement (an "Indemnified Party") shall promptly (and, in the event, at least
ten (10) days prior to the due date for any responsive pleadings, filings or
other documents) (i) notify the party for whom indemnification is sought (the
"Indemnifying Party) of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying
Party a written notice ("Claim Notice") describing in reasonable detail the
nature of the Third Party Claim, a copy of all papers served with respect to
such claim (if any), an estimate of the amount of Damages attributable to the
Third Party Claim and the basis of the Indemnified Party's request for
indemnification under this Agreement.  The failure to promptly deliver a Claim
Notice shall not relieve any Indemnifying Party of its obligations to any
Indemnified Party with respect to the related Third Party Claim except to the
extent that the resulting delay is materially prejudicial to the defense of
such claim.  Within thirty (30) days after receipt of any Claim Notice (the
"Election Period"), the Indemnifying Party shall notify the Indemnified Party
(x) whether the Indemnifying Party disputes its potential liability to the
Indemnified Party under this Article XIV with respect to such Third Party Claim
and (y) whether the Indemnifying Party desires, at the sole cost and expense of
such Indemnifying Party, to defend the Indemnified Party against such Third
Party Claim.

                 (b)      If the Indemnifying Party notifies the Indemnified
Party within the Election Period that the Indemnifying Party elects to assume
the defense of the Third Party Claim, then the Indemnifying Party shall have
the right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b).  Except as set
forth in Section 14.3(f) below, the Indemnifying Party shall have full control
of such defense and proceedings, including any compromise or settlement
thereof.  The Indemnified Party is hereby authorized, at the sole cost and
expense of the Indemnifying Party (but only if the Indemnified Party is
entitled to indemnification hereunder), to file, during the Election Period,
any motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Party and not prejudicial to the Indemnifying Party.  If requested by the
Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense
of the Indemnifying Party, to cooperate with the Indemnifying Party and their
counsel in contesting any Third Party Claim that the Indemnifying Party elects
to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person.  The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Party pursuant to this Section 14.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Party, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Party, and upon written
notification thereof, the Indemnifying Party shall not have the right to assume
the defense of such action on behalf of the Indemnified Party; provided further
that the Indemnifying Party shall not, in connection with any one such action
or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be





                                       41
<PAGE>   49
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party.  Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                 (c)      If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 14.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
14.3(b) but fails diligently and promptly to prosecute or settle the Third
Party Claim, then the Indemnified Party shall have the right to defend, at the
sole cost and expense of the Indemnifying Party (if the Indemnified Party is
entitled to indemnification hereunder), the Third Party Claim by all
appropriate proceedings, which proceedings shall be promptly and vigorously
prosecuted by the Indemnified Party to a final conclusion or settled.  The
Indemnified Party shall have full control of such defense and proceedings,
provided, however, that the Indemnified Party may not enter into, without the
Indemnifying Party's consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim.  Notwithstanding the
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes their
potential liability to the Indemnified Party under this Article XIV and if such
dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party
shall not be required to bear the costs and expenses of the Indemnified Party's
defense pursuant to this Section or of the Indemnifying Party's participation
therein at the Indemnified Party's request, and the Indemnified Party shall
reimburse the Indemnifying Party in full for all costs and expenses of such
litigation.  The Indemnifying Party may participate in, but not control, any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 14.3(c), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnifying Party
has been advised by counsel that there may be one or more legal defenses
available to it that are different from or additional to those available to the
Indemnified Party, then the Indemnifying Party may employ separate counsel and
upon written notification thereof, the Indemnified Party shall not have the
right to assume the defense of such action on behalf of the Indemnifying Party.

                 (d)      In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification
under this Agreement.  If the Indemnifying Party does not notify the
Indemnified Party within sixty (60) days from its receipt of the Indemnity
Notice that the Indemnifying Party disputes such claim, the claim specified by
the Indemnified Party in the Indemnity Notice shall be deemed a liability of
the Indemnifying Party hereunder.  If the Indemnifying Party has timely
disputed such claim, as provided above, such dispute shall be resolved by
litigation in an appropriate court of competent jurisdiction if the parties do
not reach a settlement of such dispute within thirty (30) days after notice of
a dispute is given.

                 (e)      Payments of all amounts owing by any Indemnifying
Party pursuant to this Article XIV relating to a Third Party Claim shall be
made within thirty (30) days after the latest of (i) the settlement of such
Third Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.  Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice
period or (ii) the expiration of the period for appeal of a final adjudication
of the Indemnifying Party's liability to the Indemnified Party under this
Agreement.

<PAGE>   50
                 (f)      The Indemnifying Party shall provide the Indemnified
Party with written notice of any firm offer that is made to settle or
compromise a Third Party Claim against an Indemnified Party.  If a firm offer
is made to settle such a claim solely by the payment of money damages and the
Indemnifying Party notifies the Indemnified Party in writing that the
Indemnifying Party agrees to such settlement, but the Indemnified Party elects
not to accept and agree to it, the Indemnified Party may continue to contest or
defend such Third Party Claim and, in such event, the total maximum liability

Party hereunder with respect to such a claim shall be limited to and shall not
exceed the amount of such settlement offer, plus reasonable out-of-pocket costs
and reasonable expenses (including reasonable attorneys' fees and
disbursements) to the date of notice that the Indemnifying Party desired to
accept such settlement.

                 (g)      Notwithstanding any provision herein to the contrary,
the obligation of an Indemnifying Party to provide indemnification to an
Indemnified Party for breach of any representation or warranty as provided in
Sections 14.1(a) or 14.2(a) hereof shall not take effect unless and until the
Damages asserted against or incurred in the aggregate and on a collective basis
by the Indemnified Parties pursuant to either Section 14.1 or 14.2 (as
applicable) as a result of such a breach or breaches exceeds [$____________].

         Section 14.4     Costs, Expenses and Legal Fees.  Whether or not the

fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 14.5     Tax Benefits; Insurance Proceeds.  The total amount
of any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

                 (d)      at any time prior to the Effective Date by APP if, as
a result of the conduct of due diligence and regulatory compliance procedures,
APP deems termination to be advisable; or

                 (e)      by APP or the Company if the Merger shall not have

         Section 15.2     Effect of Termination.  Except as set forth in
Section 16.3, in the event this Agreement is terminated pursuant to this
Article XV, this Agreement shall forthwith become void.

                                  ARTICLE XVI

                   Nondisclosure of Confidential Information

         Section 16.1     Non-Disclosure Covenant.  Each Company and NewCo
recognize and acknowledge that each has in the past, currently has, and in the
future may possibly have, access to certain Confidential Information of APP and
the Surviving Corporation that is valuable, special and a unique asset of such
entity's business.  APP and APP Sub acknowledge that they had in the past,
currently have, and in the future may possibly have, access to certain
Confidential Information of each Company and NewCo that is valuable, special
and a unique asset of each such business.  Each Company, NewCo, APP, and APP
Sub, severally, agree that they will not disclose such Confidential Information
to any person, firm, corporation, association or other entity for any purpose
or reason whatsoever, except (a) to authorized representatives of APP, APP Sub,
Surviving Corporation, NewCo and each Company and (b) to counsel and other
advisers to APP, APP Sub, Surviving Corporation, NewCo and each Company
provided that such advisers (other than counsel) agree to the confidentiality
provisions of this Section 16.1, unless (i) such information becomes available
to or known by the public generally through no fault of the Company, NewCo, APP
or APP Sub, as the case may be, (ii) disclosure is required by law or the order
of any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (iii) each Company, NewCo,
APP or APP Sub, as the case may be, shall, if possible, give prior written
notice thereof to the Company, NewCo, APP or APP Sub and provide each Company,
APP or APP Sub with the opportunity to contest such disclosure, (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, or (iv)
the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Merger or otherwise.  In the event of a breach
or threatened breach by each Company, on the one hand, and APP or APP Sub, on
the other hand, of the provisions of this Section, APP, APP Sub, the Surviving
Corporation, NewCo and each Company shall be entitled to an injunction
restraining the other party, as the case may be, from disclosing, in whole or
in part, such Confidential Information.  Nothing herein shall be construed as
prohibiting any of such parties from pursuing any other available remedy for
such breach or threatened breach, including the recovery of damages.

         Section 16.2     Damages.  Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, APP Sub, the Surviving
Corporation, NewCo and each Company agree that, in the event of a breach by
either of them of the foregoing covenant, the covenant may be enforced against
them by injunctions and restraining orders.

         Section 16.3     Survival.  The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

modified or supplemented only by an instrument in writing executed by all the
parties hereto.  Any waiver of any terms

<PAGE>   52
and conditions hereof must be in writing, and signed by the parties hereto.
The waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 17.2     Assignment.  Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any party hereto,
except by APP to a wholly owned subsidiary of APP; provided that any such
assignment shall not relieve APP of its obligations hereunder.

         Section 17.3     Parties in Interest; No Third Party Beneficiaries.
Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto.  APP and APP Sub
acknowledge and agree that the rights and remedies of each Company under this
Agreement will be directly available to the Stockholders as third party
beneficiaries of the rights and remedies of each Company under this Agreement,
including, without limitation, the rights and remedies under Article 14 hereof
to indemnification from APP and APP Sub against Damages incurred by the
Stockholders resulting from a breach by APP or APP Sub of any representation,
warranty or covenant of APP or APP Sub contained herein.  Except as provided in
the preceding sentence or as otherwise provided herein, neither this Agreement
nor any other agreement contemplated hereby shall be deemed to confer upon any
person not a party hereto or thereto any rights or remedies hereunder or
thereunder.

         Section 17.4     Entire Agreement.  This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding
the subject matter hereof, and supersede all prior agreements and
understandings, both written and oral, among the parties, or any of them, with
respect to the subject matter hereof.

         Section 17.5     Severability.  If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 17.6     Survival of Representations, Warranties and
Covenants.  The representations, warranties and covenants contained herein
shall survive the Closing and all statements contained in any certificate,
exhibit or other instrument delivered by or on behalf of each Company, any
Stockholder, APP or APP Sub pursuant to this Agreement shall be deemed to have
been representations and warranties by the Company, such Stockholder, APP and
APP Sub.  Notwithstanding any provision in this Agreement to the contrary, the

the second anniversary of the Closing Date except that (a) the representations
and warranties set forth in Section 3.21 with respect to environmental matters
shall survive for a period of ten (10) years, (b) the representations and
warranties set forth in Section 3.30 with respect to tax matters shall survive
until such time as the limitations period has run for all tax periods ended

for a period of six (6) years and (d) solely for purposes of Section 14.1(c)
and Section 14.2(c), and solely to the extent that any party to be indemnified
pursuant to such provisions actually incurs liability under the Securities Act,
the Exchange Act or any other federal or state securities law, the
representations and warranties set forth therein shall survive until the
expiration of any applicable limitations period.

         Section 17.7     Governing Law.  THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN

the Company affecting or that would reasonably be likely to affect the Company
Common Stock or the operations, business condition, (financial or otherwise), or
results of operations of the Company which (i) if successful, may, individually
or in the aggregate, have a Material Adverse Effect on the Company or (ii) could
adversely affect the ability of the Company or any Company Subsidiary to effect
the transactions contemplated hereby, and to the knowledge of the Company there
is no basis for any such action or any state of facts or occurrence of any event
which would reasonably be likely to give rise to the foregoing. There are no
unsatisfied judgments against the Company or any Company Subsidiary or any
licensed professional or other individual affiliated with the Company or any
Company Subsidiary relating to services provided on behalf of the Company or any
Company Subsidiary or any consent decrees to which any of the foregoing is

requirement of any governmental body, agency, authority or court binding on it,

to the operation of its business and which requires payments in excess of
$12,000 per year (the "Lease Agreements"). The Company has delivered to APP true
and complete copies of all of the Lease Agreements. Each Lease Agreement is
valid, effective and in full force in accordance with its terms, and there is
not under any such lease (i) any existing or claimed material default by the
Company or any Company Subsidiary (as applicable) or event of material default
or event which with notice or lapse of time, or both, would constitute a
material default by the Company or any Company Subsidiary (as applicable) and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Company, or, (ii) to the knowledge of the Company, any existing
material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party. To the knowledge of the

consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver to
APP in writing such consents as are necessary to effect a valid and binding
transfer or assignment of the Company's or any Company Subsidiary's rights
thereunder. The Company has a good, clear, valid and enforceable leasehold
interest under each of the Lease Agreements. The Lease Agreements comply with
the exceptions to ownership interests and compensation arrangements set out in

intangible) and any rights or interests therein which it purports to own
including, without limitation, all the property and assets reflected in the
Company Current Financial Statements; and (ii) owns such rights, interests,
assets and property free and clear of all Encumbrances, title defects or
objections (except for taxes not yet due and payable). The personal property

         Section 3.17 Contracts and Commitments.

                  (a) The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the

medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the

payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all

provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000 in

other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is with
unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP of the assets and
properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP. In every instance where consent is necessary, the Company
shall, on or before the Closing Date, use reasonable good faith efforts to
obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts. Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. Notwithstanding the foregoing, the Company shall not transfer to APP
any contracts or agreements relating to the provision of professional medical
services or other such agreements and contracts that APP consents to in writing
to be transferred to NewCo in the Spin-off Transaction. No contract with a
health care provider or Payor has been materially amended or terminated within
the last twelve (12) months.

intention of any other party to exercise any right to cancel or terminate any
contract, agreement or instrument required to be disclosed pursuant to Section
3.17(a), and to the knowledge of the Company there are no fact(s) that would
justify the exercise of such a right; and (ii) does not currently contemplate,
or have reason to

                                       12

believe any other Person currently contemplates, any amendment or change to any

any kind or nature necessary to be filed by the Company with any governmental
agency or authority have been properly completed and timely filed in compliance
with all applicable requirements, except where failure to so file would not have

         Section 3.23 Insurance Policies. The Disclosure Schedules list and
briefly describe the Company's policies of insurance to which the Company or any
Company Subsidiary is a party or under which the Company or any Company
Subsidiary, officer or director thereof is or has been covered at any time
during the last five (5) years preceding the date of this Agreement relating to
the business of the Company or any Company Subsidiary (the "Insurance
Policies"). All of the Insurance Policies are valid, outstanding and enforceable
policies, except as may be limited by applicable bankruptcy, insolvency or
similar laws affecting creditors' rights generally or the availability of
equitable remedies and all premiums with respect thereto which are due and
payable are currently paid. All Insurance Policies currently maintained by the
Company or any Company Subsidiary ("Current Policies") taken together, (i)
provide adequate insurance coverage for the assets, properties and operations of
the Company and its Affiliates for all risks normally insured against by a
Person carrying on a substantially similar business or businesses as the Company
and its Affiliates, (ii) are sufficient for compliance with legal and
contractual requirements to which the Company or any of its Affiliates is a
party or by which any of them may be bound, and (iii) shall be maintained in
force (including the payment of all premiums and compliance with their terms)
without interruption up to and including the Closing Date. True, complete and
correct copies of all Insurance Policies have been provided to APP. Neither the
Company nor any Company Subsidiary nor any officer or director thereof has
received any notice or other written communication from any issuer of any
Current Policy cancelling such policy, materially increasing any deductibles or
retained


                                       16
<PAGE>   22

amounts thereunder, or materially increasing the annual or other premiums
payable thereunder and, to the knowledge of the Company, no such cancellation or
increase of deductibles, retainages or premiums is threatened. There are no
outstanding claims, settlements or premiums owed against any Insurance Policy,
and all required notices have been given and all known potential or actual
claims under any Insurance Policy have been presented in due and timely fashion.
Within the five (5) years preceding the Agreement, neither the Company nor any
Company Subsidiary has filed a written application for any professional
liability insurance coverage which has been denied by an insurance agency or
carrier. The Disclosure Schedules also set forth a list of all claims under any
Insurance Policy in excess of $10,000 per occurrence filed by the Company or any
Company Subsidiary during the immediately preceding three-year period. Each
Physician Employee has, at all times while a Physician Employee, maintained or
been covered by professional malpractice insurance in such types and amounts as
are customary for such a physician practicing the same type of medicine in the
same geographic area.

         Section 3.24      Accounts Receivable; Payors.

                  (a) The Disclosure Schedules set forth a list and aging of all
accounts receivable of the Company as of March 31, 1997, which list is complete,
true and accurate in all material respects. All such accounts receivable arose
in the ordinary course of business and have not been previously written off as
bad debts and, are, to the extent still uncollected, to the knowledge of the
Company collectible in the ordinary course of business, net of reserves for
doubtful and uncollectible accounts shown in the Company Financial Statements or
on the accounting records of the Company (which reserves are calculated
consistent with generally accepted accounting principles and past practice).

                  (b) The Disclosure Schedules set forth (i) a true, correct and
complete list of the names and addresses of each Payor of the Company as of such
date, which accounted for more than 5% of the revenues of the Company in the
fiscal year ended December 31, 1996, or which is reasonably expected to account
for more than 5% of the revenues of the Company for the fiscal year to end
December 31, 1997, and (ii) a single line item listing for all private-pay
patients in the aggregate of the Company. The Company has satisfactory relations
with such Payors set forth in (i) above and none of such Payors has notified the
Company that it intends to discontinue its relationship with the Company or to
deny any payments due from, or any claims for payment submitted to any such
party.

         Section 3.25      Accounts Payable; Suppliers.

                  (a) The Disclosure Schedules set forth a true and complete (i)
list of the accounts payable of the Company as of March 31, 1997, and (ii) list
of each individual indebtedness owed by the Company of $5,000 or more, setting
forth the payee and the amount of indebtedness.

                  (b) The Disclosure Schedules set forth a true, correct and
complete list of the names and addresses of each of the providers/suppliers of
products or services to the Company (including, without limitation all
non-Physician Employee providers of care to patients) which accounted for a
dollar volume of purchases paid for by the Company in excess of $25,000 for the
fiscal year ended December 31, 1996, or which is reasonably expected to account
for a dollar volume of purchases paid for by the Company in excess of $25,000
for the fiscal year to end December 31, 1997.

         Section 3.26 Inventory. All items of inventory on the Company Current
Balance Sheet contained in the Company Financial Statements consisted, and all
such items on hand on the date of this Agreement consist, and all such items on
hand at the Effective Time will consist, net of all applicable reserves with
respect thereto (calculated consistent with past practice), of items of a
quality and a quantity usable and saleable in the ordinary course of the
Company's business and conform to generally accepted standards in the industry
of which the Company is a part. The value of the inventories reflected on the
Company Current Balance Sheet contained in the Company Financial Statements are
net of adequate reserves for damaged, excess, and unusable items. Purchase
commitments of the Company for inventory are not materially in excess of normal
requirements, and none of such purchase commitments are at prices in excess of
prevailing market prices at the time of such purchase commitment.

licensed employee or independent contractor of the Company (i) is the holder of

("Governmental Programs"). The Company, the Stockholders, and each Physician
Employee has a current provider number for such Governmental Programs and with
such private non-governmental programs (including without limitation any private
insurance program) under which the Company is presently receiving payments
directly or indirectly from any Payor for patient care provided by such
Physician Employee, licensed employee or independent contractor (such
non-governmental programs herein referred to as "Private Programs"). A true,

numbers and participating physician contracts under 1842(h) of the Social
Security Act), and provider agreements, is set forth in the Disclosure
Schedules, true, complete and correct copies of which have been provided to APP.
No violation, default, order or deficiency exists with respect to any of the
items listed in the Disclosure Schedules except for such violations, defaults,
orders or deficiencies which would not be reasonably likely to have a Material
Adverse Effect on the Company, and there is no action pending or to the
Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program, and
no event has occurred which, with or without notice or lapse of time, or both,
would constitute grounds for a violation, order or deficiency with respect to
any of the items listed in the Disclosure Schedules to revoke, withdraw or
suspend any material license to operate its business as is presently being
conducted by it. To the knowledge of the Company, there has been no decision not
to renew any existing agreement with any provider or Payor relating to the
Company's business as presently being conducted by it. Neither the Company nor
any Physician Employee (i) has had his/her/its professional license, Drug
Enforcement Agency number, Medicare/Medicaid provider status or staff privileges
at any hospital or diagnostic imaging center suspended, relinquished, terminated
or revoked (including orders that have been entered by any such entities but

licensing board, state agency, regulatory body or authority, hospital, Payor or
specialty board (including orders that have been entered by any such entities

federal or state authority that could result in any demand or reimbursement
under the Medicare, Medicaid or Government Programs or any exclusion or which

similar action.

                  (b) The Company is not required, or for the 72-month period
prior to the Effective Time was not required, to file any cost reports or other
reports with any Governmental Program or Private Program.

         Section 3.28 Inspections and Investigations. Neither the right of the
Company, or any Physician Employee, nor the right of any licensed professional
or other individual affiliated with the Company to receive reimbursements
pursuant to any Governmental Program or Private Program has been terminated or
otherwise materially and adversely affected as a result of any investigation or
action whether by any federal or state governmental regulatory authority or
other third party. No Physician Employee, licensed professional or other
individual affiliated with the business has, during the past three (3) years
prior to the Effective Time, had their professional license or staff privileges
limited, suspended or revoked by any governmental regulatory authority or
agency, hospital, integrated delivery system, trade association, professional
review organization, accrediting organization or certifying agency (including
orders that have been entered by any such entities but stayed). True, correct
and complete copies of all reports, correspondence, notices and other documents

         Section 8.1 Consummation of Agreement. APP will take all action
reasonably necessary to cause the consummation of the transactions contemplated
hereby in accordance with their terms and conditions and take all corporate and

otherwise affect any of the representations, warranties, covenants or agreements
of APP under this Agreement.

         Section 8.4  Notification of Certain Matters.  APP shall promptly 
inform the Company in writing of (a) any notice of, or other communication
relating to, a default or event that, with notice or

alternatives in accordance with Department of Labor Regulation 2550.404C-1. APP

favorable determination from the IRS that NewCo is not a member of an affiliated
service group (as defined in Section 414(m) of the Code) or a recipient

Code). Costs associated with the establishment and design of the New Qualified
Plan shall be paid by APP. NewCo shall be responsible for funding any
contributions to, or any ongoing administrative costs of, the New Qualified

         Section 9.1 Filings; Other Action.

         (a) The Company shall cooperate with APP to promptly prepare and file
with the SEC the Registration Statements on Form S-1 and Form S-4 (or other
appropriate Forms) to be filed by APP in connection with its Initial Public
Offering and offering of the shares of APP Common Stock to the Target Interest
Holders pursuant to the transactions contemplated by this Agreement and the

concerning the Company and NewCo as may be reasonably requested in connection
with any such action in a timely manner.

         (b) The Company and APP and each separately represent and warrant that
(i) in the case of the Company, none of the written information or documents
supplied or to be supplied by it specifically for inclusion in the Registration
Statements, by exhibit or otherwise and (ii) in the case of APP, will, at the
time the Registration Statements and each amendment and supplement thereto, if
any, becomes effective under the Securities Act, none of them contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading. The Company shall be
entitled to review the Registration Statements and each of the amendments
thereto, if any, prior to the time each becomes effective under the Securities
Act. The Company shall have no responsibility for information contained in the
Registration Statements except for information provided by the Company
specifically for inclusion therein. The Company's review of the Registration
Statements shall not diminish or otherwise affect the representations, covenants
and warranties of APP contained in this Agreement.

         (c) The Company shall, upon request, furnish APP with all information
concerning itself, its subsidiaries, directors, officers, partners, Stockholders
and NewCo, and such other matters as may be reasonably requested by APP in

agrees that, with respect to the representations and warranties of such party
contained in this Agreement, such party shall have the continuing obligation
until the Closing to supplement or amend promptly the Disclosure Schedules with
respect to any matter that would have been or would be required to be set forth
or described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on the Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Disclosure Schedule that constitutes or reflects a Material Adverse Effect on
APP may be made unless the Company consents to such amendment or supplement. For
purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 10.1 and 11.1 have been
fulfilled, the Disclosure Schedules hereto shall be deemed to be the Disclosure
Schedules as amended or supplemented pursuant to this Section 9.2. In the event
that the Company seeks to amend or supplement a Disclosure Schedule pursuant to
this Section 9.2 and APP does not consent to such amendment or supplement, or
APP seeks to amend or supplement a Disclosure Schedule pursuant to this Section

by mutual consent as set forth in Section 15.1(a) hereof.

         Section 9.3 Actions Contrary to Stated Intent. No party hereto will
knowingly, either before or after the Merger, take any action that would prevent
the Merger from qualifying as a tax-free exchange within the meaning of Section
351 of the Code.

         Section 9.4 Public Announcements. The parties hereto will consult with
each other before issuing any press release or making any public statement with
respect to this Agreement and the transactions contemplated hereby and, except
as may be required by applicable law, will not issue any such press release or
make any such public statement prior to such consultation, although the
foregoing shall not apply to any disclosure by APP in any filing with the DOJ,
FTC or SEC.

         Section 9.5 Expenses. Each party to this Agreement shall be solely
responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by the Company and NewCo shall be paid by the Company in
full immediately prior to the Closing and any such expenses shall be the sole
responsibility of the Stockholders following the Closing Date and not APP.

         Section 9.6 Patient Confidentiality. APP shall agree to keep all
records and information regarding the patients of the Company and NewCo
confidential in accordance with all applicable laws.

         Section 9.7 Registration Statements. APP shall prepare and file the

competent tax counsel to the effect that there is not substantial authority,
within the meaning of Section 6662(d)(2)(B)(i) of the Code, to report the Merger
as a Reorganization and such opinion either is furnished prior to the Effective
Time or is based on facts or events not known at the Effective Time. Each party
shall provide to each other party such tax information, reports, returns, or
schedules as may be reasonably required to assist such party in accounting for
and reporting the Merger as a Reorganization.

         (c) The parties agree that no Stockholder shall be liable for any taxes
incurred by the Company and for which APP has successor liability therefor which
arise solely as a result of the Merger or the consummation of the transactions
contemplated hereby; provided that the foregoing shall not limit or otherwise be
deemed a waiver of any right of indemnification under Section 14.1 for a breach
of any representation, warranty or covenant of the Company or any Stockholder.

         Section 13.3 Current Public Information. APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

attorneys' fees and expenses (including, without limitation, all costs of

(collectively, "Damages") asserted against or incurred by such individuals
and/or entities arising out of or resulting from:

                  (a) a breach by the Company of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of the Company
contained in this Agreement or in any Disclosure Schedule or certificate
delivered thereunder;

                  (b) any violation (or alleged violation) by the Company and/or

obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                  (c) any liability under the Securities Act, the Exchange Act
or any other federal or state "blue sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any (i) untrue statement
of material fact in any Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto relating to the Company
(including any Company Subsidiary) or NewCo required to be stated therein or
(ii) failure to state information required to be stated therein or necessary to
make the statements therein not misleading, arising which untrue statement or
failure to state information arises or result solely from information provided
in writing to APP or its counsel by the Company or any Stockholder or their
agents specifically for inclusion in any such Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto.

         Section 14.2 Indemnification by APP. Subject to the terms and
conditions of this Article XIV, APP hereby agrees to indemnify, defend and hold
the Stockholders, the Company and NewCo and their respective directors,
officers, stockholders, employees, agents, attorneys, consultants and Affiliates
harmless from and against all Damages asserted against or incurred by such
individuals and/or entities arising out of or resulting from:

                  (a) a breach by APP of any representation or warranty (without
giving effect to any Material Adverse Effect qualifier contained as part of any
such representation or warranty) or covenant of APP contained in this Agreement
or in any schedule or certificate delivered hereunder; and

                  (b) any liability under the Securities Act, the Exchange Act
or any other federal or state "blue sky" or securities law or regulation, at

of material fact in any Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto or (ii) failure to state

upon any actual or alleged untrue statement of material fact or an omission to
state a material fact relating to NewCo, the Company or any Stockholder to the
extent derived from any information provided in writing by the Company or a
Company Subsidiary or any of their agents contained in the representations and
warranties set forth in this Agreement or any certificate, exhibit, schedule or
instrument required to be delivered under this Agreement.)

                  Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

         Section 14.3 Conditions of Indemnification.  All claims for 
indemnification under this Agreement shall be asserted and resolved as follows:

                  (a) Any party claiming indemnification under the Agreement (an
"Indemnified Party") shall promptly (and, in the event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party for whom indemnification is sought (the "Indemnifying
Party) of any third-party claim or claims asserted against the Indemnified Party
("Third Party Claim") that could give rise to a right of indemnification under
this Agreement and (ii) transmit to the Indemnifying Party a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of Damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement. The failure to promptly deliver a Claim Notice shall not relieve any
Indemnifying Party of its obligations to any Indemnified Party with respect to
the related Third Party Claim except to the extent that the resulting delay is
materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (x) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article XIV
with respect to such Third Party Claim and (y) whether the Indemnifying Party
desires, at the sole cost and expense of such Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

                  (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may employ separate counsel at the expense of the Indemnifying Party, and
upon written notification thereof, the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of the Indemnified Party;
provided further that the Indemnifying Party shall not, in connection with any
one such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                  (c) If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have


                                       39
<PAGE>   45

the right to defend, at the sole cost and expense of the Indemnifying Party (if
the Indemnified Party is entitled to indemnification hereunder), the Third Party
Claim by all appropriate proceedings, which proceedings shall be promptly and
vigorously prosecuted by the Indemnified Party to a final conclusion or settled.
The Indemnified Party shall have full control of such defense and proceedings,
provided, however, that the Indemnified Party may not enter into, without the
Indemnifying Party's consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim. Notwithstanding the
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes their
potential liability to the Indemnified Party under this Article XIV and if such
dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party
shall not be required to bear the costs and expenses of the Indemnified Party's
defense pursuant to this Section or of the Indemnifying Party's participation
therein at the Indemnified Party's request, and the Indemnified Party shall
reimburse the Indemnifying Party in full for all costs and expenses of such
litigation. The Indemnifying Party may participate in, but not control, any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 14.3(c), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnifying Party has
been advised by counsel that there may be one or more legal defenses available
to it that are different from or additional to those available to the
Indemnified Party, then the Indemnifying Party may employ separate counsel and
upon written notification thereof, the Indemnified Party shall not have the
right to assume the defense of such action on behalf of the Indemnifying Party.

                  (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                  (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period for appeal of a final adjudication of the
Indemnifying Party's liability to the Indemnified Party under this Agreement.

                  (f) The Indemnifying Party shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Party to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Party desired to accept such settlement.

                  (g) Notwithstanding any provision herein to the contrary, the
obligation of an Indemnifying Party to provide indemnification to an Indemnified
Party for breach of any representation or warranty as provided in Sections
14.1(a) or 14.2(a) hereof shall not take effect unless and until the Damages
asserted against or incurred in the aggregate and on a collective basis by the
Indemnified Parties pursuant to either Section 14.1 or 14.2 (as applicable) as a
result of such a breach or breaches exceeds $100,000.

         Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.

contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

                  (c) at any time prior to the Effective Date by the Company if

in any material respect with any covenant or agreement contained herein, and any
such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

                  (d) at any time prior to the Effective Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures, APP
deems termination to be advisable; or

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

         Section 16.1 Non-Disclosure Covenant. The Company and NewCo recognize
and acknowledge that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP that is
valuable, special and a unique asset of such entity's business. APP acknowledges
that it had in the past, currently has, and in the future may possibly have,
access to certain Confidential Information of the Company and NewCo that is
valuable, special and a unique asset of each such business. The Company, NewCo
and APP, severally, agree that they will not disclose such Confidential
Information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
APP, NewCo and the Company and (b) to counsel and other advisers to APP, NewCo
and the Company provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 16.1, unless (i) such information
becomes available to or known by the public generally through no fault of the
Company, NewCo or APP, as the case may be, (ii) disclosure is required by law or
the order of any governmental authority under color of law, provided, that prior
to disclosing any information pursuant to this clause (ii) the Company, NewCo or
APP, as the case may be, shall, if possible, give prior written notice thereof
to the Company, NewCo or APP and provide the Company or APP with the opportunity
to contest such disclosure, (iii) the disclosing party reasonably believes that
such disclosure is required in connection with the defense of a lawsuit against
the disclosing party, or (iv) the disclosing party is the sole and exclusive
owner of such Confidential Information as a result of the Merger or otherwise.
In the event of a breach or threatened breach by the Company, on the one hand,
and APP, on the other hand, of the provisions of this Section, APP, NewCo and
the Company shall be entitled to an injunction restraining the other party, as
the case may be, from disclosing, in whole or in part, such Confidential
Information. Nothing herein shall be construed as prohibiting any of such
parties from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages.

         Section 16.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, NewCo and the Company agree that, in the event of
a breach by either of them of the foregoing covenant, the covenant may be
enforced against them by injunctions and restraining orders.

         Section 16.3 Survival. The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

modified or supplemented only by an instrument in writing executed by all the
parties hereto. Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto. The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

the Company under this Agreement, including, without limitation, the rights and
remedies under Article 14 hereof to indemnification from APP against Damages
incurred by the Stockholders resulting from a breach by APP of any
representation, warranty or covenant of APP contained herein. Except as provided
in the preceding sentence or as otherwise provided herein, neither this
Agreement nor any other agreement contemplated hereby shall be deemed to confer
upon any person not a party hereto or thereto any rights or remedies hereunder
or thereunder.

         Section 17.4 Entire Agreement. This Agreement and the agreements
contemplated hereby or delivered in connection herewith constitute the entire
agreement of the parties regarding the subject matter hereof, and supersede all

to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

instrument delivered by or on behalf of the Company, any Stockholder or APP
pursuant to this Agreement shall be deemed to have been representations and
warranties by the Company, such Stockholder and APP. Notwithstanding any
provision in this Agreement to the contrary, the representations and warranties

such provisions actually incurs liability under the Securities Act, the Exchange
Act or any other federal or state securities law, the representations and
warranties set forth therein shall survive until the expiration of any
applicable limitations period.

         Section 17.7 Governing Law.  THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES
GOVERNING CONFLICTS OF LAWS) OF THE STATE OF KANSAS.

         Section 17.8 Captions.  The captions in this Agreement are for

surrendered by the Stockholders, the certificates for Company Common Stock
shall, for all purposes, represent solely the right to receive Merger
Consideration as determined in accordance with the provisions of Exhibit B
attached hereto and Section 2.10 hereof, if applicable.  At the Effective Time,
each share of Company Common Stock converted into Merger Consideration shall by
virtue of the Merger and without any action on the part of the holders thereof,

         Section 3.13     No Violation of Law.  Neither the Company nor any
Company Subsidiary has been, nor shall be as of the Effective Time (by virtue
of any action, omission to act, contract to which it is a party or any
occurrence or state of facts whatsoever), in violation of any applicable local,
state or federal law, ordinance, regulation, order, injunction or decree, or
any other requirement of any governmental body, agency, authority or court
binding on it, or relating to its properties, assets or business or its
advertising, sales or pricing practices, except for violations which,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on the Company.

         Section 3.14     Lease Agreements.  The Disclosure Schedules contain a
true, accurate and complete list of all the lease agreements and license
agreements to which the Company or any Company Subsidiary is a party and
pursuant to which the Company or any Company Subsidiary leases (whether as
lessor or lessee) or licenses (whether as licensor or licensee) any real or
personal property related to the operation of its business and which requires
payments in excess of $12,000 per year (the "Lease Agreements").  The Company
has delivered to APP true and complete copies of all of the Lease Agreements.
Each Lease Agreement is valid, effective and in full force in accordance with
its terms, and there is not under any such lease (i) any existing or claimed
material default by the Company or any Company Subsidiary (as applicable) or
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by the Company or any Company Subsidiary
(as applicable) and, individually or in the aggregate, may reasonably result in
a Material Adverse Effect on the Company, or, (ii) to the knowledge of the
Company, any existing material default by any other party under any of the
Lease Agreements or any event of material default or event which with notice or
lapse of time, or both, would constitute a material default by any such party.
To the knowledge of the Company, there is no pending or threatened reassessment
of any property covered by the Lease Agreements.  The Company or any Company
Subsidiary will use reasonable good faith efforts to obtain, prior to the
Effective Time, the consent of each landlord or lessor whose consent is
required to the assignment of the Lease Agreements and will use reasonable good
faith efforts to deliver to APP in writing such consents as are necessary to
effect a valid and binding transfer or assignment of the Company's or any
Company Subsidiary's rights thereunder.  The Company has a good, clear, valid
and enforceable leasehold interest under each of the Lease Agreements.  The
Lease Agreements comply with the exceptions to ownership interests and
compensation arrangements set out in 42 U.S.C. Section  1395nn, 42 C.F.R.
Section  1001.952, and any similar applicable state law safe harbor or other
exemption provisions.

         Section 3.15     Real and Personal Property.

                 (a)      Neither the Company nor any Company Subsidiary owns
any interest (other than the Lease Agreements) in real property.

                 (b)      The Company and any Company Subsidiary (i) has good
title to all of its properties and assets (real, personal and mixed, tangible
and intangible) and any rights or interests therein





                                       11
<PAGE>   18
which it purports to own including, without limitation, all the property and
assets reflected in the Company Current Financial Statements; and (ii) owns
such rights, interests, assets and property free and clear of all Encumbrances,
title defects or objections (except for taxes not yet due and payable).  The
personal property presently used in connection with the operation of the
business of the Company and the Company Subsidiaries constitutes the necessary
personal property assets to continue operation of the Company and any Company
Subsidiary.

         Section 3.16     Indebtedness for Borrowed Money.  Except for trade
payables incurred in the ordinary course of business, the Company does not have
any direct or indirect indebtedness for borrowed money, including indebtedness
by way of lease-purchase arrangements or guarantees, and is not obligated in
any manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

         Section 3.17     Contracts and Commitments.

                 (a)      The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies,
of each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate
(other than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health
maintenance organization, other managed care organization or other third-party
provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of
obligations of third parties requiring the Company to make, or setting forth
conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000
in any fiscal year or $25,000 in the aggregate and that are not cancelable by
providing notice of sixty (60) days or less.  All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is
with unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP of the assets and
properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP.  In every instance where consent is necessary, the
Company shall, on or before the Closing Date, use reasonable good faith efforts
to obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts.  Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement.  Notwithstanding the foregoing, the Company shall not transfer to
APP any contracts or agreements relating to the provision of professional
medical services or other such agreements and contracts that APP consents to in
writing to be transferred to NewCo in the Spin-off Transaction.  No contract
with a health care provider or Payor has been materially amended or terminated
within the last twelve (12) months.

or intention of any other party to exercise any right to cancel or terminate
any contract, agreement or instrument required to be disclosed pursuant to
Section 3.17(a), and to the knowledge of the Company there are no fact(s) that
would justify the exercise of such a right; and (ii) does not currently
contemplate, or have reason to believe any other Person currently contemplates,
any amendment or change to any such contract, agreement or instrument.

         Section 3.18     Employee Matters.  The Company is not currently a
party to any employment contract (except for oral employment agreements which

sharing, bonus, stock option, stock purchase or other nonqualified benefit or
compensation commitments, benefit plans, arrangements or plans (whether written

Employment Opportunity Commission or any federal, state or local agency or

                 (b)      Administration.  Each Employee Benefit Plan has been

notice that any Employee Benefit Plan is currently the subject of an audit,
investigation, enforcement action or other similar proceeding conducted by any

reasonably likely to result, directly or indirectly, (including through any
obligation of indemnification or contribution), in any taxes, penalties or
other liability to APP or any of its Affiliates.

                 (e)      Claims and Litigation.  No pending or, to the

the Code and, to the best knowledge of the Company and each Stockholder, has
been continually qualified under the applicable Section of the Code since the

Company's knowledge, have been threatened that could result in the revocation
of any such favorable determination letter or ruling.

each Employee Benefit Plan subject to Title IV of ERISA, the assets of each
such plan are at least equal in value to the present value of accrued benefits
determined on an ongoing basis as of the date hereof.  With respect to each
Employee Benefit Plan described in Section 501(c)(9) of the Code, the assets of
each such plan are at least equal in value to the present value of accrued
benefits, based upon the most recent actuarial valuation as of a date no more
than ninety (90) days prior to the date hereof.  The Disclosure Schedules

to determine the present value of accrued benefits under all Employee Benefit
Plans subject to actuarial assumptions.

                 (h)      Excise Taxes.  Neither the Company nor any member of

412 of the Code.

                 (j)      PBGC.  No facts or circumstances are known to the
Company that would result in the imposition of liability against APP or any of
its Affiliates by the Pension Benefit Guaranty Corporation ("PBGC") as a result
of any act or omission by the Company or any member of a Controlled Group.  No
reportable event (within the meaning of Section 4043 of ERISA) for which the

Employee Benefit Plan subject to the requirements of Title IV of ERISA.

                 (k)      Retirees.  The Company has no obligation or
commitment to provide medical, dental or life insurance benefits to or on
behalf of any of its employees who may retire or any of its former employees
who have retired except as may be required pursuant to the continuation of
coverage provisions of Section 4980B of the Code and the applicable provisions
of ERISA.

                 (l)      Other Compensation Arrangements.  Neither the Company
nor, to the Company's knowledge, any Stockholder or Physician Employee is a

Compensation and Liability Act) any Hazardous Substance (as defined herein)
that would be reasonably likely to give rise to any Environmental Liabilities
(as defined in subsection (e) below) for the Company under any applicable
Environmental Law that had, or would reasonably be likely to have, a Material
Adverse Effect on the Company.  Neither the Company nor any Company Subsidiary
has engaged in any activity or failed to undertake any activity which action or
failure to act has given, or would reasonably be likely to give, rise to any
Environmental Liabilities or enforcement action by any federal, state or local
regulatory agency or authority, or has resulted, or would reasonably be likely
to result, in any fine or penalty imposed pursuant to any Environmental Law.
Schedule 3.21(b) discloses any known presence of asbestos in or on the

such contamination had, or would be reasonably likely to have, a Material
Adverse Effect on the Company.

                 (d)      There have been no environmental audits and other
similar reports which have been prepared by, for or, to the knowledge of the
Company, concerning the Company or any Company Subsidiary within the five (5)

         laws, ordinances, codes, regulations, rules, policies and orders
         (including without limitation, Medical Waste Laws) that are intended

         to, or list or define air, water, groundwater, solid waste, hazardous,
         toxic, or radioactive substances, materials, wastes, pollutants or
         contaminants, or which are intended to assure the safety of employees,
         workers or other persons, including the public in each case as in
         effect on the date hereof.

                 "Environmental Liabilities" shall mean all liabilities of the

         Section 3.23     Insurance Policies.  The Disclosure Schedules list
and briefly describe the Company's policies of insurance to which the Company
or any Company Subsidiary is a party or under which the Company or any Company
Subsidiary, officer or director thereof is or has been covered at any time

Policies").  All of the Insurance Policies are valid, outstanding and
enforceable policies, except as may be limited by applicable bankruptcy,

availability of equitable remedies and all premiums with respect thereto which
are due and payable are currently paid.  All Insurance Policies currently
maintained by the Company or any Company Subsidiary ("Current Policies") taken

cancelling such policy, materially increasing any deductibles or retained
amounts thereunder, or materially increasing the annual or other premiums
payable thereunder and, to the knowledge of the Company, no such cancellation
or increase of deductibles, retainages or premiums is threatened.  There are no
outstanding claims, settlements or premiums owed against any Insurance Policy,
and all required notices have been given and all known potential or actual
claims under any Insurance Policy have been presented in due and timely
fashion.  Within the five (5) years preceding the Agreement, neither the
Company nor any Company Subsidiary has filed a written application for any
professional liability insurance coverage which has been denied by an insurance
agency or carrier.  The Disclosure Schedules also set forth a list of all
claims under any Insurance Policy in excess of $10,000 per occurrence filed by
the Company or any Company Subsidiary during the immediately preceding

previously written off as bad debts and, are, to the extent still uncollected,
to the knowledge of the Company collectible in the ordinary course of business,
net of reserves for doubtful and uncollectible accounts shown in the Company

reserves are calculated consistent with generally accepted accounting
principles and past practice).

                 (b)      The Disclosure Schedules set forth (i) a true,
correct and complete list of the names and addresses of each Payor of the
Company as of such date, which accounted for more than 5% of the revenues of

expected to account for more than 5% of the revenues of the Company for the
fiscal year to end December 31, 1997, and (ii) a single line item listing for
all private-pay patients in the aggregate of the Company.  The Company has
satisfactory relations with such Payors set forth in (i) above and none of such
Payors has notified the Company that it intends to discontinue its relationship
with the Company or to deny any payments due from, or any claims for payment
submitted to any such party.

         Section 3.25     Accounts Payable; Suppliers.

non-Physician Employee providers of care to patients) which accounted for a
dollar volume of purchases paid for by the Company in excess of $25,000 for the
fiscal year ended December 31, 1996, or which is reasonably expected to account
for a dollar volume of purchases paid for by the Company in excess of $25,000
for the fiscal year to end December 31, 1997.

         Section 3.26     Inventory.  All items of inventory on the Company
Current Balance Sheet contained in the Company Financial Statements consisted,
and all such items on hand on the date of this Agreement consist, and all such
items on hand at the Effective Time will consist, net of all applicable
reserves with respect thereto (calculated consistent with past practice), of
items of a quality and a quantity usable and saleable in the ordinary course of
the Company's business and conform to generally accepted standards in the
industry of which the Company is a part.  The value of the inventories

licensed employee or independent contractor of the Company (i) is the holder of

numbers and participating physician contracts under 1842(h) of the Social
Security Act), and provider agreements, is set forth in the Disclosure
Schedules, true, complete and correct copies of which have been provided to

the Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the

both, would constitute grounds for a violation, order or deficiency with
respect to any of the items listed in the Disclosure Schedules to revoke,
withdraw or suspend any material license to operate its business as is
presently being conducted by it.  To the knowledge of the Company, there has
been no decision not to renew any existing agreement with any provider or Payor
relating to the Company's business as presently being conducted by it.  Neither
the Company nor any Physician Employee (i) has had his/her/its professional

or disciplined by any licensing board, state agency, regulatory body or
authority, hospital, Payor or specialty board (including orders that have been
entered by any such entities but stayed), or (iii) is the subject of an initial

any demand or reimbursement under the Medicare, Medicaid or Government Programs
or any exclusion or which monetary penalty under federal or state law or (iv)
has had a final judgment or settlement entered against him/her/it in connection
with a malpractice or similar action.

                 (b)      The Company is not required, or for the 72-month
period prior to the Effective Time was not required, to file any cost reports
or other reports with any Governmental Program or Private Program.

professional or other individual affiliated with the Company to receive
reimbursements pursuant to any Governmental Program or Private Program has been
terminated or otherwise materially and adversely affected as a result of any
investigation or action whether by any federal or state governmental regulatory
authority or other third party.  No Physician Employee, licensed professional
or other individual affiliated with the business has, during the past three (3)
years prior to the Effective Time, had their professional license or staff
privileges limited, suspended or revoked by any governmental regulatory
authority or agency, hospital, integrated delivery system, trade association,
professional review organization, accrediting organization or certifying agency

           Closing Date Representations and Warranties of the Company

         The Company represents and warrants that the following will be true
and correct on the Closing Date as if made on that date:

         Section 5.1      Organization and Good Standing; Qualification.  NewCo
is a professional corporation duly organized, validly existing and in good
standing under the laws of its state of organization, with all requisite
corporate power and authority to carry on the business in which it intends to
engage, to own the properties it intends to own, and to execute and deliver the
Service Agreement, the Security Agreement and the Physician Employment
Agreements and consummate the transactions and perform the services
contemplated thereby.  NewCo is duly qualified and licensed to do business and
is in good standing in all jurisdictions where the nature of its intended
business makes such qualification necessary, which jurisdictions are listed in
the Disclosure Schedules, except where the failure to be so qualified shall not
have a Material Adverse Effect on NewCo.

         Section 5.2      Capitalization.  The authorized capital stock of
NewCo consists of [_____] shares of NewCo Common Stock, of which [______]
shares are issued and outstanding, and no shares of capital stock of NewCo are
held in treasury.  The Stockholders own all of the issued and outstanding
shares of NewCo Common Stock, free and clear of any Encumbrance.  Each
outstanding share of NewCo Common Stock has been legally and validly issued and
is fully paid and nonassessable.  There exist no options, warrants,
subscriptions or other rights to purchase, or securities convertible into or
exchangeable for, any of the authorized or outstanding securities of NewCo.  No
shares of capital stock of NewCo have been issued or disposed of in violation
of the preemptive rights, rights of first refusal or similar rights of any of
NewCo's stockholders.

that have been delivered or made available to APP are true, correct and

         Section 5.4      Authorization and Validity.  The execution, delivery
and performance by NewCo of the Service Agreement, the Security Agreement, the
Physician Employment Agreements and the other agreements contemplated thereby,
and the consummation of the transactions and provision of services contemplated
thereby, have been duly authorized by the Board of Directors of NewCo.  The
Service Agreement, the Security Agreement, the Physician Employment Agreements
and each other agreement contemplated thereby will be as of the Closing Date
duly executed and delivered by NewCo and will constitute valid and binding
obligations of NewCo enforceable against NewCo in accordance with their
respective terms, except as may be limited by applicable bankruptcy, or other
laws affecting creditors' rights generally, or by general equity principles, or
by public policy.

         Section 5.5      No Violation.  Neither the execution, delivery or
performance of the Service Agreement, the Security Agreement, the Physician
Employment Agreements or the other agreements contemplated thereby nor the
consummation of the transactions or provision of services contemplated thereby
will (a) conflict with, or result in a violation or breach of the terms,
conditions or provisions of, or constitute a default under, the articles or
certificate of incorporation or bylaws of NewCo, or (b) violate or conflict
with any applicable local, state or federal law, ordinance, regulation, order,
injunction or decree, or any other requirement of any governmental body, agency
or authority or court binding on it, or relating to its property or business.

         Section 5.6      No Business, Agreements, Assets or Liabilities.
NewCo has not commenced business since its incorporation.  Other than its
articles or certificate of incorporation and bylaws, and as of the Closing
Date, the Service Agreement, the Security Agreement, the Physician Employment
Agreements, and the other contracts and agreements assigned to NewCo as part of
the Spin-Off Transaction, NewCo is not a party to or subject to any agreement,
indenture or other instrument.  NewCo does not own any assets (tangible or
intangible) other than the consideration received upon the issuance of shares
of its capital stock or pursuant to the Spin-Off Transaction, and NewCo does
not have any liabilities, accrued, contingent or otherwise (known or unknown
and asserted or unasserted) other than those assumed pursuant to the Spin-Off
Transaction.

         Section 5.7      Compliance with Laws.  NewCo has complied with all
applicable laws, regulations and licensing requirements and has filed with the
proper authorities all necessary statements and reports, except where failure
to so comply or file would not, individually or in the aggregate, have a
Material Adverse Effect on NewCo.

best efforts to obtain the unanimous approval of its Stockholders to the

taken by the consenting Stockholders as may be required by applicable law.

Section 7.8 hereof, the Company will take all action reasonably necessary to
cause the Company to perform its obligations under this Agreement and all
related agreements and to consummate the Merger and other transactions

<PAGE>   36
where applicable, or vested accrued benefits for which the Company or any entity
might have any liability whatsoever arising from any tax-qualified plan as
required under applicable law.  The Company acknowledges that the purpose and
intent of this covenant is to assure that APP shall have no liability whatsoever
at any time after the Closing Date with respect to any such tax-qualified plan,
unless such plan is merged with a plan sponsored by APP.

         Section 7.11     Accounting and Tax Matters.  The Company will not
change in any material respect the accounting methods or practices followed by

not make any material tax election except in the ordinary course of business
consistent with past practice, change any material tax election already made,
adopt any tax accounting method except in the ordinary course of business
consistent with past practice, change any tax accounting method, enter into any
closing agreement, settle any tax claim or assessment or consent to any tax
claim or assessment or any waiver of the statute of limitations for any such

and pay all taxes required to be paid by it, on or before the Closing Date.

         Section 7.12     Spin-Off Transaction.  The Company shall form,
organize and incorporate NewCo in the state of New York, and the articles or
certificate of incorporation and bylaws of NewCo shall be in form and substance
reasonably satisfactory to APP.  Except for consummating the Spin-Off
Transaction, NewCo shall not commence business until the Closing Date.  On or
prior to the Closing, the Company shall take all actions and execute all
documents, agreements or instruments necessary pursuant to and in compliance
with applicable law to effect the Spin-Off Transaction, including without
limitation, the following:  Prior to the Closing, the Company shall transfer to
NewCo good, valid and marketable title to all of the Company's right, title and
interest in and to the Employee Benefit Plans, all contracts and agreements and
other assets listed on the Disclosure Schedules (to be delivered by the Company
prior to Closing, which schedule will be subject to the approval of APP, which
approval shall not be unreasonably withheld) which by law either cannot be
acquired or cannot be used by APP because they relate to the practice of
medicine or radiology, and shall contribute to NewCo such other consideration
and assets of the Company as may be required under applicable law, in exchange
for the issuance by NewCo of shares of NewCo Common Stock, such shares being
all of the issued and outstanding shares of NewCo Common Stock.  The Company
shall then distribute the shares of NewCo Common Stock to the Stockholders in
proportion to their respective ownership interest in the Company.

         Section 7.13     "F" Reorganization.  The Company shall convert its
corporate status from that of a professional medical corporation to that of a
general business corporation in a transaction which will qualify as a tax-free
transaction under Section 368(a)(2)(F) of the Code (the "F" Reorganization").
The Company shall prepare and execute all documents necessary to effectuate the
"F" Reorganization prior to the Closing.  At or prior to the Closing, the
Company shall cause an amendment to this Agreement to be executed which will
reflect the changes which result from the "F" Reorganization.

for inclusion in the Registration Statements, by exhibit or otherwise and (ii)
in the case of APP, will, at the time the Registration Statements and each
amendment and supplement thereto, if any, becomes effective under the
Securities Act, none of them contain any untrue statement of a material fact or

make the statements therein, in the light of the circumstances under which they
were made, not misleading.  The Company shall be entitled to review the
Registration Statements and each of the amendments thereto, if any, prior to
the time each becomes effective under the Securities Act.  The Company shall
have no responsibility for information contained in the Registration Statements
except for information provided by the Company specifically for inclusion

diminish or otherwise affect the representations, covenants and warranties of
APP contained in this Agreement.

         (c)     The Company shall, upon request, furnish APP with all
information concerning itself, its subsidiaries, directors, officers, partners,
Stockholders and NewCo, and such other matters as may be reasonably requested

contained in this Agreement, such party shall have the continuing obligation
until the Closing to supplement or amend promptly the Disclosure Schedules with
respect to any matter that would have been or would be required to be set forth
or described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on the Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Disclosure Schedule that constitutes or reflects a Material Adverse Effect on
APP may be made unless the Company consents to such amendment or supplement.
For purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 10.1 and 11.1 have
been fulfilled, the Disclosure Schedules hereto shall be deemed to be the
Disclosure Schedules as amended or supplemented pursuant to this Section 9.2.
In the event that the Company seeks to amend or supplement a Disclosure
Schedule pursuant to this Section 9.2 and APP does not consent to such
amendment or supplement, or APP seeks to amend or supplement a Disclosure
Schedule pursuant to this Section 9.2, and the Company does not consent, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
15.1(a) hereof.

         Section 9.3      Actions Contrary to Stated Intent.  No party hereto
will knowingly, either before or after the Merger, take any action that would
prevent the Merger from qualifying as a tax-free exchange within the meaning of
Sections 351 or 368 of the Code, as applicable.

         Section 9.4      Public Announcements.  The parties hereto will
consult with each other before issuing any press release or making any public
statement with respect to this Agreement and the transactions contemplated
hereby and, except as may be required by applicable law, will not issue any

consultation, although the foregoing shall not apply to any disclosure by APP
in any filing with the DOJ, FTC or SEC.

solely responsible for their own fees and expenses with respect to the
transactions contemplated herein including, without limitation, the fees
charged by attorneys, accountants and financial advisors retained by such
parties.  The fees and expenses incurred by the Company and NewCo in connection
with the Merger shall be paid by the Company Stockholders in full immediately
prior to the Closing and such expenses shall be the sole responsibility of the
Stockholders following the Closing Date and not APP.

         Section 9.6      Patient Confidentiality.  APP shall agree to keep all

(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of APP contained in
this Agreement or in any schedule or certificate delivered hereunder; and

                 (b)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon





                                       38
<PAGE>   45
any untrue statements of material fact in any Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or required to be stated therein or failure to state information
necessary to make the statements therein not misleading (except for any
liability based upon any actual or alleged untrue statement of material fact or
an omission to state a material fact relating to NewCo, the Company or any
Stockholder which was derived from any information provided in writing by the
Company or a Company Subsidiary or any of their agents contained in the
representations and warranties set forth in this Agreement or any certificate,
exhibit, schedule or instrument required to be delivered under this Agreement.)

                 Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

         Section 14.3     Conditions of Indemnification.  All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                 (a)      Any party claiming indemnification under the
Agreement (an "Indemnified Party") shall promptly (and, in the event, at least
ten (10) days prior to the due date for any responsive pleadings, filings or
other documents) (i) notify the party for whom indemnification is sought (the
"Indemnifying Party) of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying
Party a written notice ("Claim Notice") describing in reasonable detail the
nature of the Third Party Claim, a copy of all papers served with respect to
such claim (if any), an estimate of the amount of Damages attributable to the
Third Party Claim and the basis of the Indemnified Party's request for
indemnification under this Agreement.  The failure to promptly deliver a Claim
Notice shall not relieve any Indemnifying Party of its obligations to any
Indemnified Party with respect to the related Third Party Claim except to the
extent that the resulting delay is materially prejudicial to the defense of
such claim.  Within thirty (30) days after receipt of any Claim Notice (the
"Election Period"), the Indemnifying Party shall notify the Indemnified Party
(x) whether the Indemnifying Party disputes its potential liability to the
Indemnified Party under this Article XIV with respect to such Third Party Claim
and (y) whether the Indemnifying Party desires, at the sole cost and expense of
such Indemnifying Party, to defend the Indemnified Party against such Third
Party Claim.

                 (b)      If the Indemnifying Party notifies the Indemnified
Party within the Election Period that the Indemnifying Party elects to assume
the defense of the Third Party Claim, then the Indemnifying Party shall have
the right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b).  Except as set
forth in Section 14.3(f) below, the Indemnifying Party shall have full control
of such defense and proceedings, including any compromise or settlement
thereof.  The Indemnified Party is hereby authorized, at the sole cost and
expense of the Indemnifying Party (but only if the Indemnified Party is
entitled to indemnification hereunder), to file, during the Election Period,
any motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Party and not prejudicial to the Indemnifying Party.  If requested by the
Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense
of the Indemnifying Party, to cooperate with the Indemnifying Party and their
counsel in contesting any Third Party Claim that the Indemnifying Party elects
to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person.  The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Party pursuant to this Section 14.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Party, then the Indemnified Party may





                                       39
<PAGE>   46
employ separate counsel at the expense of the Indemnifying Party, and upon
written notification thereof, the Indemnifying Party shall not have the right
to assume the defense of such action on behalf of the Indemnified Party;
provided further that the Indemnifying Party shall not, in connection with any
one such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm
of attorneys at any time for the Indemnified Party, which firm shall be
designated in writing by the Indemnified Party.  Notwithstanding the foregoing,
the Indemnifying Party shall be prohibited from confessing or settling any
criminal allegations brought against the Indemnified Party without the express
written consent of the Indemnified Party.

                 (c)      If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 14.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
14.3(b) but fails diligently and promptly to prosecute or settle the Third
Party Claim, then the Indemnified Party shall have the right to defend, at the
sole cost and expense of the Indemnifying Party (if the Indemnified Party is
entitled to indemnification hereunder), the Third Party Claim by all
appropriate proceedings, which proceedings shall be promptly and vigorously
prosecuted by the Indemnified Party to a final conclusion or settled.  The
Indemnified Party shall have full control of such defense and proceedings,
provided, however, that the Indemnified Party may not enter into, without the
Indemnifying Party's consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim.  Notwithstanding the
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes their
potential liability to the Indemnified Party under this Article XIV and if such
dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party
shall not be required to bear the costs and expenses of the Indemnified Party's
defense pursuant to this Section or of the Indemnifying Party's participation
therein at the Indemnified Party's request, and the Indemnified Party shall
reimburse the Indemnifying Party in full for all costs and expenses of such
litigation.  The Indemnifying Party may participate in, but not control, any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 14.3(c), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnifying Party
has been advised by counsel that there may be one or more legal defenses
available to it that are different from or additional to those available to the
Indemnified Party, then the Indemnifying Party may employ separate counsel and
upon written notification thereof, the Indemnified Party shall not have the
right to assume the defense of such action on behalf of the Indemnifying Party.

                 (d)      In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification
under this Agreement.  If the Indemnifying Party does not notify the
Indemnified Party within sixty (60) days from its receipt of the Indemnity
Notice that the Indemnifying Party disputes such claim, the claim specified by
the Indemnified Party in the Indemnity Notice shall be deemed a liability of
the Indemnifying Party hereunder.  If the Indemnifying Party has timely
disputed such claim, as provided above, such dispute shall be resolved by
litigation in an appropriate court of competent jurisdiction if the parties do
not reach a settlement of such dispute within thirty (30) days after notice of
a dispute is given.

                 (e)      Payments of all amounts owing by any Indemnifying
Party pursuant to this Article XIV relating to a Third Party Claim shall be
made within thirty (30) days after the latest of (i) the settlement of such
Third Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.  Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice
period or (ii) the expiration of the period





                                       40
<PAGE>   47
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

                 (f)      The Indemnifying Party shall provide the Indemnified
Party with written notice of any firm offer that is made to settle or
compromise a Third Party Claim against an Indemnified Party.  If a firm offer
is made to settle such a claim solely by the payment of money damages and the
Indemnifying Party notifies the Indemnified Party in writing that the
Indemnifying Party agrees to such settlement, but the Indemnified Party elects
not to accept and agree to it, the Indemnified Party may continue to contest or
defend such Third Party Claim and, in such event, the total maximum liability
of the Indemnifying Party to indemnify or otherwise reimburse the Indemnified
Party hereunder with respect to such a claim shall be limited to and shall not
exceed the amount of such settlement offer, plus reasonable out-of-pocket costs
and reasonable expenses (including reasonable attorneys' fees and
disbursements) to the date of notice that the Indemnifying Party desired to
accept such settlement.

                 (g)      Notwithstanding any provision herein to the contrary,
the obligation of an Indemnifying Party to provide indemnification to an
Indemnified Party for breach of any representation or warranty as provided in
Sections 14.1(a) or 14.2(a) hereof shall not take effect unless and until the
Damages asserted against or incurred in the aggregate and on a collective basis
by the Indemnified Parties pursuant to either Section 14.1 or 14.2 (as
applicable) as a result of such a breach or breaches exceeds $100,000.

         Section 14.4     Costs, Expenses and Legal Fees.  Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 14.5     Tax Benefits; Insurance Proceeds.  The total amount
of any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

                                   ARTICLE XV

                                  Termination

         Section 15.1     Termination.  This Agreement may be terminated and
the Merger and the Acquisitions may be abandoned:

                 (a)      at any time prior to the Effective Date by mutual
agreement of all parties;

                 (b)      at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and
delivered by the Company or any Stockholder pursuant to this Agreement is or
becomes untrue or breached in any material respect or if the Company or any
Stockholder fails to comply in any material respect with any material covenant
or agreement contained herein, and any such misrepresentation, noncompliance or
breach is not cured, waived or eliminated within thirty (30) days after receipt
of written notice thereof;

                 (c)      at any time prior to the Effective Date by the
Company if any representation or warranty of APP contained in this Agreement or
in any certificate or other document executed and delivered by APP pursuant to
this Agreement is or becomes untrue in any material respect of if APP fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;





                                       41
<PAGE>   48
                 (d)      at any time prior to the Effective Date by APP if, as
a result of the conduct of due diligence and regulatory compliance procedures,
APP deems termination to be advisable; or

                 (e)      by APP or the Company if the Merger shall not have
been consummated by September 30, 1997.

         Section 15.2     Effect of Termination.  Except as set forth in
Section 16.3, in the event this Agreement is terminated pursuant to this
Article XV, this Agreement shall forthwith become void.

                                  ARTICLE XVI

                   Nondisclosure of Confidential Information

         Section 16.1     Non-Disclosure Covenant.  The Company and NewCo
recognize and acknowledge that each has in the past, currently has, and in the
future may possibly have, access to certain Confidential Information of APP
that is valuable, special and a unique asset of such entity's business.  APP
acknowledges that it had in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of the Company and
NewCo that is valuable, special and a unique asset of each such business.  The
Company, NewCo and APP, severally, agree that they will not disclose such
Confidential Information to any person, firm, corporation, association or other
entity for any purpose or reason whatsoever, except (a) to authorized
representatives of APP, NewCo and the Company and (b) to counsel and other
advisers to APP, NewCo and the Company provided that such advisers (other than
counsel) agree to the confidentiality provisions of this Section 16.1, unless
(i) such information becomes available to or known by the public generally
through no fault of the Company, NewCo or APP, as the case may be, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii) the Company, NewCo or APP, as the case may be, shall, if
possible, give prior written notice thereof to the Company, NewCo or APP and
provide the Company or APP with the opportunity to contest such disclosure,
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, or
(iv) the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Merger or otherwise.  In the event of a breach
or threatened breach by the Company, on the one hand, and APP, on the other
hand, of the provisions of this Section, APP, NewCo and the Company shall be
entitled to an injunction restraining the other party, as the case may be, from
disclosing, in whole or in part, such Confidential Information.  Nothing herein
shall be construed as prohibiting any of such parties from pursuing any other
available remedy for such breach or threatened breach, including the recovery
of damages.

         Section 16.2     Damages.  Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, NewCo and the Company agree
that, in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

         Section 16.3     Survival.  The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                 Miscellaneous

         Section 17.1     Amendment; Waivers.  This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto.  Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto.  The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 17.2     Assignment.  Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any party hereto,
except by APP to a wholly owned subsidiary of APP; provided that any such
assignment shall not relieve APP of its obligations hereunder.

         Section 17.3     Parties in Interest; No Third Party Beneficiaries.
Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto.  APP
acknowledges and agrees that the rights and remedies of the Company under this
Agreement will be directly available to the Stockholders as third party
beneficiaries of the rights and remedies of the Company under this Agreement,
including, without limitation, the rights and remedies under Article 14 hereof
to indemnification from APP against Damages incurred by the Stockholders
resulting from a breach by APP of any representation, warranty or covenant of
APP contained herein.  Except as provided in the preceding sentence or as
otherwise provided herein, neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party
hereto or thereto any rights or remedies hereunder or thereunder.

         Section 17.4     Entire Agreement.  This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding
the subject matter hereof, and supersede all prior agreements and
understandings, both written and oral, among the parties, or any of them, with
respect to the subject matter hereof.

         Section 17.5     Severability.  If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 17.6     Survival of Representations, Warranties and
Covenants.  The representations, warranties and covenants contained herein
shall survive the Closing and all statements contained in any certificate,
exhibit or other instrument delivered by or on behalf of the Company, any
Stockholder or APP pursuant to this Agreement shall be deemed to have been
representations and warranties by the Company, such Stockholder and APP.
Notwithstanding any provision in this Agreement to the contrary, the
representations and warranties contained herein shall survive the Closing until
the second anniversary of the Closing Date except that (a) the representations
and warranties set forth in Section 3.21 with respect to environmental matters
shall survive for a period of ten (10) years, (b) the representations and
warranties set forth in Section 3.30 with respect to tax matters shall survive
until such time as the limitations period has run for all tax periods ended
prior to the Closing Date, (c) the representations and warranties contained in
Section 3.27 and Section 3.33 with respect to healthcare matters shall survive
for a period of six (6) years and (d) solely for purposes of Section 14.1(c)

pursuant to such provisions actually incurs liability under the Securities Act,
the Exchange Act or any other federal or state securities law, the
representations and warranties set forth therein shall survive until the
expiration of any applicable limitations period.

         Section 17.7     Governing Law.  THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

party shall keep this Agreement and its terms confidential, and shall make no
press release or public disclosure, either written or oral, regarding the
transactions contemplated by this Agreement without the prior knowledge and
consent of the other parties hereto; provided that the foregoing shall not
prohibit any disclosure (a) by press release, filing or otherwise that APP has
determined in its good faith judgment and after advice of legal counsel to be
required by federal securities laws or the rules of the National Association of
Securities Dealers, (b) to attorneys, accountants, investment bankers or other
agents of the parties assisting the parties in connection with the transactions

attached hereto and Section 2.10 hereof, if applicable. At the Effective Time,
each share of Company Common Stock converted into Merger Consideration shall by
virtue of the Merger and without any action on the part of the holders thereof,

lieu thereof reflecting such Stockholder's proportionate interest in a share of
APP Common Stock multiplied by the Initial Public Offering Price.

and authority to own, operate and lease its assets and properties and to carry

is in good standing in each jurisdiction where the character of the property
owned or leased by it or the nature of its activities makes such qualification
necessary, except where such failure to be so qualified or in good standing
would not have a Material Adverse Effect on the Company. Copies of the articles
or certificates of incorporation and all amendments thereto of the Company and
each Company Subsidiary and the bylaws of the Company and each Company
Subsidiary, as amended, and copies of the corporate minutes of the Company, all
of which have been or will be made available to APP for review, are true and
complete as in effect on the date of this Agreement, and in the case of the
corporate minutes, accurately reflect all material proceedings of the
Stockholders and directors of the Company (and all committees thereof). The

herein, and the consummation by the Company of the transactions contemplated
hereby and thereby are within the Company's respective corporate powers and have
been duly authorized by all necessary action on the part of the Company's Board
of Directors. Subject to the approval of this Agreement and the Merger by the
Stockholders, this Agreement has been duly executed by the Company, and this
Agreement and all other agreements and obligations entered into and undertaken
in connection with the transactions contemplated hereby to which the Company is
a party constitute, or upon execution will constitute, valid and binding
agreements of the Company, enforceable against it in accordance with their
respective terms, except as enforceability may be limited by bankruptcy or other
laws affecting the enforcement of creditors' rights generally, or by general
equity principles, or by public policy.

            Section 3.3 Governmental Authorization. Other than complying with
the provisions of the applicable state corporate laws regarding the approval of
the Merger and the filing of the Certificates of Merger (as contemplated by
Section 2.3) and any other required documents related to the Merger, and other

herein, and the consummation of the transactions contemplated hereby and thereby
by the Company require no action by or in respect of, or filing with, any
governmental body, agency, official or authority.

issued and is fully paid and nonassessable, and was issued pursuant to a valid
exemption from registration under (i) the Securities Act of 1933, as amended,
and (ii) all applicable state securities laws. No shares of Company Common Stock
are owned by the Company in treasury. No shares of Company Common Stock have
been issued or disposed of in violation of any preemptive rights, rights of
first refusal or similar rights of any of the Stockholders. Other than Company
Common Stock, the Company has no securities, bonds, debentures, notes or other
obligations the holders of which have the right to vote (or are convertible into
or exercisable for securities having the right to vote) with the Stockholders on
any matter.

            Section 3.5 Transactions in Capital Stock. There exist no Company
Rights. The Company has no obligation (contingent or otherwise) to purchase,

Subject to approval of this Agreement and the Merger by the Stockholders of the
Company, the execution, delivery and performance by the Company of this
Agreement and any other documents contemplated hereby (with or without the

any governmental or regulatory body or authority or any other third party except

a violation of any provision of the Company's articles or certificate of
incorporation or bylaws, (iii) will not conflict with, result in a violation of,

requirement of any governmental body, agency, authority or court binding on it,
or relating to its properties, assets or business or its advertising, sales or

            Section 3.14 Lease Agreements. The Disclosure Schedules contain a

lessor or lessee) or licenses (whether as licensor or licensee) any real or
personal property related to the operation of its business and which requires
payments in excess of $12,000 per year (the "Lease Agreements"). The Company has
delivered to APP true and complete copies of all of the Lease Agreements. Each
Lease Agreement is valid, effective and in full force in accordance with its
terms, and there is not under any such lease (i) any existing or claimed
material default by the Company or any Company Subsidiary (as applicable) or
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by the Company or any Company Subsidiary (as

Material Adverse Effect on the Company, or, (ii) to the knowledge of the
Company, any existing material default by any other party under any of the Lease
Agreements or any event of material default or event which with notice or lapse
of time, or both, would constitute a material default by any such party. To the

the consent of each landlord or lessor whose consent is required to the
assignment of the Lease Agreements and will use reasonable good faith efforts to
deliver to APP in writing such consents as are necessary to effect a valid and
binding transfer or assignment of the Company's or any Company Subsidiary's
rights thereunder. The Company has a good, clear, valid and enforceable
leasehold interest under each of the Lease Agreements. The Lease Agreements
comply with the exceptions to ownership interests and compensation arrangements

applicable state law safe harbor or other exemption provisions.

title to all of its properties and assets (real, personal and mixed, tangible
and intangible) and any rights or interests therein



                                       11

which it purports to own including, without limitation, all the property and
assets reflected in the Company Current Financial Statements; and (ii) owns such
rights, interests, assets and property free and clear of all Encumbrances, title
defects or objections (except for taxes not yet due and payable). The personal
property presently used in connection with the operation of the business of the
Company and the Company Subsidiaries constitutes the necessary personal property
assets to continue operation of the Company and any Company Subsidiary.

            Section 3.16 Indebtedness for Borrowed Money. Except for trade
payables incurred in the ordinary course of business, the Company does not have

unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP of the assets and
properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP. In every instance where consent is necessary, the Company
shall, on or before the Closing Date, use reasonable good faith efforts to
obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts. Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. Notwithstanding the foregoing, the Company shall not transfer to APP
any contracts or agreements relating to the provision of professional medical
services or other such agreements and contracts that APP consents to in writing
to be transferred to NewCo in the Spin-off Transaction. No contract with a
health care provider or Payor has been materially amended or terminated within
the last twelve (12) months.

                    (b) Administration. Each Employee Benefit Plan has been

that any Employee Benefit Plan is currently the subject of an audit,
investigation, enforcement action or other similar proceeding conducted by any

reasonably likely to result, directly or indirectly, (including through any
obligation of indemnification or contribution), in any taxes, penalties or other
liability to APP or any of its Affiliates.

                    (e) Claims and Litigation. No pending or, to the Company's

and, to the best knowledge of the Company and each Stockholder, has been
continually qualified under the applicable Section of the Code since the
effective date of such Employee Benefit Plan. No proceedings exist or, to the
Company's knowledge, have been threatened that could result in the revocation of
any such favorable determination letter or ruling.

                    (g) Funding Status. No accumulated funding deficiency

benefits, based upon the most recent actuarial valuation as of a date no more
than ninety (90) days prior to the date hereof. The Disclosure Schedules

Employee Benefit Plan which has been subject to Title IV of ERISA or Section 412
of the Code.

                    (j) PBGC. No facts or circumstances are known to the Company
that would result in the imposition of liability against APP or any of its
Affiliates by the Pension Benefit Guaranty Corporation ("PBGC") as a result of
any act or omission by the Company or any member of a Controlled Group. No
reportable event (within the meaning of Section 4043 of ERISA) for which the

would be reasonably likely to give rise to any Environmental Liabilities (as
defined in subsection (e) below) for the Company under any applicable
Environmental Law that had, or would reasonably be likely to have, a Material
Adverse Effect on the Company. Neither the Company nor any Company Subsidiary
has engaged in any activity or failed to undertake any activity which action or
failure to act has given, or would reasonably be likely to give, rise to any
Environmental Liabilities or enforcement action by any federal, state or local
regulatory agency or authority, or has resulted, or would reasonably be likely

Company.

                    (d) There have been no environmental audits and other
similar reports which have been prepared by, for or, to the knowledge of the

end December 31, 1997, and (ii) a single line item listing for all private-pay
patients in the aggregate of the Company. The Company has satisfactory relations

Company's business and conform to generally accepted standards in the industry
of which the Company is a part. The value of the inventories reflected on the
Company Current Balance Sheet contained in the Company Financial Statements are
net of adequate reserves for damaged, excess, and unusable items. Purchase
commitments of the Company for inventory



                                       17

are not materially in excess of normal requirements, and none of such purchase
commitments are at prices in excess of prevailing market prices at the time of
such purchase commitment.

            Section 3.27 Licenses, Authorization and Provider Programs.

                    (a) The Company, and each Physician Employee and other
licensed employee or independent contractor of the Company (i) is the holder of

("Governmental Programs"). The Company, the Stockholders, and each Physician
Employee has a current provider number for such Governmental Programs and with
such private non-governmental programs (including without limitation any private
insurance program) under which the Company is presently receiving payments

No violation, default, order or deficiency exists with respect to any of the
items listed in the Disclosure Schedules except for such violations, defaults,
orders or deficiencies which would not be reasonably likely to have a Material
Adverse Effect on the Company, and there is no action pending or to the
Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program, and
no event has occurred which, with or without notice or lapse of time, or both,
would constitute grounds for a violation, order or deficiency with respect to
any of the items listed in the Disclosure Schedules to revoke, withdraw or
suspend any material license to operate its business as is presently being
conducted by it. To the knowledge of the Company, there has been no decision not
to renew any existing agreement with any provider or Payor relating to the
Company's business as presently being conducted by it. Neither the Company nor
any Physician Employee (i) has had his/her/its professional license, Drug

similar action.

                    (b) The Company is not required, or for the 72-month period
prior to the Effective Time was not required, to file any cost reports or other
reports with any Governmental Program or Private Program.

the Company, or any Physician Employee, nor the right of any licensed
professional or other individual affiliated with the Company to receive
reimbursements pursuant to any Governmental Program or Private Program has been
terminated or otherwise materially and adversely affected as a result of any
investigation or action whether by any federal or state governmental regulatory
authority or other third party. No Physician Employee, licensed professional or
other individual affiliated with the business has, during the past three (3)
years prior to the Effective Time, had their professional license or staff
privileges limited, suspended or revoked by any governmental regulatory
authority or agency, hospital, integrated delivery system, trade association,
professional review organization, accrediting organization or certifying agency

                    this Agreement or any of the agreements attached as exhibits
                    hereto, other than as required to discharge its or their
                    fiduciary duties.

including, without limitation, deeds, title documents, leases, patient lists,

its employees which shall occur no later than three (3) days subsequent to
execution hereof by the Company), accountants, counsel and agents of the Company
in connection with such investigation of the properties and business of the

conducted in such a manner as to minimize the disruption to the Company's
ongoing business operations.

            Section 7.4 Acquisition Proposals. The Company shall not, and shall
cause each of its directors, officers, employees or agents not to directly or

negotiations or discussions with respect to any offer or proposal to acquire all
or a substantial portion of the business, properties or capital stock of the
Company, whether by merger, consolidation, share exchange, business combination,
purchase of assets or otherwise; or

                    (b) except as required by law or pursuant to subpoena or
court order, disclose to any Person, other than APP or its agents, any
information not customarily disclosed concerning the business, assets,
liabilities, properties and personnel of the Company, or, without APP's prior
written approval, afford to any Person other than APP and its agents access to
the properties, books or records of the Company. If the Company receives any
offer or proposal after the date hereof, written or otherwise, of the type
referred to above, the Company shall promptly inform APP of such offer or
proposal, decline such offer and furnish APP with a copy thereof if such offer
or proposal is in writing.

otherwise affecting the Company which, if pending on the date of this Agreement,
would have been required to have been disclosed to APP hereunder or which relate
to the consummation of the transactions contemplated by this Agreement;

            Section 7.7 Intentionally omitted.

            Section 7.8 Stockholders' Consent. The Company shall use its best
efforts to obtain the unanimous approval of its Stockholders to the Merger. In
seeking the approval of its Stockholders, the Company shall provide each
Stockholder with the Form S-4 which shall include information as may be required
by applicable law or as APP shall deem appropriate. The Board of Directors of
the Company shall recommend the approval of the Merger by the Stockholders of
the Company. If the Stockholders' approval is not unanimous, the Company shall
give notice to the nonconsenting Stockholders of the action taken by the
consenting Stockholders as may be required by applicable law.

            Section 7.9 Obligations of Company and Stockholders. Subject to
Section 7.8 hereof, the Company will take all action reasonably necessary to
cause the Company to perform its obligations under this Agreement and all
related agreements and to consummate the Merger and other transactions
contemplated hereby and thereby on the terms and conditions set forth in this
Agreement and such agreements; provided, however, that this covenant shall not
require the Company to make any expenditures that are not expressly set forth in
this Agreement or otherwise contemplated herein.

            Section 7.10 Funding of Accrued Employee Benefits. The Company
hereby covenants and agrees that it will take whatever steps are necessary to
pay for or fund completely any accrued benefits,



                                       29

<PAGE>   36

where applicable, or vested accrued benefits for which the Company or any entity
might have any liability whatsoever arising from any tax-qualified plan as
required under applicable law. The Company acknowledges that the purpose and
intent of this covenant is to assure that APP shall have no liability whatsoever
at any time after the Closing Date with respect to any such tax-qualified plan,
unless such plan is merged with a plan sponsored by APP.

            Section 7.11 Accounting and Tax Matters. The Company will not change
in any material respect the accounting methods or practices followed by the
Company (including any material change in any assumption underlying, or any
method of calculating, any bad debt, contingency or other reserve), except as
may be required by generally accepted accounting principles. The Company will
not make any material tax election except in the ordinary course of business
consistent with past practice, change any material tax election already made,
adopt any tax accounting method except in the ordinary course of business
consistent with past practice, change any tax accounting method, enter into any
closing agreement, settle any tax claim or assessment or consent to any tax
claim or assessment or any waiver of the statute of limitations for any such
claim or assessment. The Company will duly, accurately and timely (without
regard to any extensions of time) file all returns, information statements and
other documents relating to taxes of the Company required to be filed by it, and
pay all taxes required to be paid by it, on or before the Closing Date.

            Section 7.12 Spin-Off Transaction. The Company shall form, organize
and incorporate NewCo in the state of New York, and the articles or certificate
of incorporation and bylaws of NewCo shall be in form and substance reasonably
satisfactory to APP. Except for consummating the Spin-Off Transaction, NewCo
shall not commence business until the Closing Date. On or prior to the Closing,
the Company shall take all actions and execute all documents, agreements or
instruments necessary pursuant to and in compliance with applicable law to
effect the Spin-Off Transaction, including without limitation, the following:
Prior to the Closing, the Company shall transfer to NewCo good, valid and
marketable title to all of the Company's right, title and interest in and to the
Employee Benefit Plans, all contracts and agreements and other assets listed on
the Disclosure Schedules (to be delivered by the Company prior to Closing, which
schedule will be subject to the approval of APP, which approval shall not be
unreasonably withheld) which by law either cannot be acquired or cannot be used
by APP because they relate to the practice of medicine or radiology, and shall
contribute to NewCo such other consideration and assets of the Company as may be
required under applicable law, in exchange for the issuance by NewCo of shares
of NewCo Common Stock, such shares being all of the issued and outstanding
shares of NewCo Common Stock. The Company shall then distribute the shares of
NewCo Common Stock to the Stockholders in proportion to their respective
ownership interest in the Company.

            Section 7.13 "F" Reorganization. The Company shall convert its
corporate status from that of a professional medical corporation to that of a
general business corporation in a transaction which will qualify as a tax-free
transaction under Section 368(a)(2)(F) of the Code (the "F" Reorganization").
The Company shall prepare and execute all documents necessary to effectuate the
"F" Reorganization prior to the Closing. At or prior to the Closing, the Company
shall cause an amendment to this Agreement to be executed which will reflect the
changes which result from the "F" Reorganization.

                                  ARTICLE VIII

                                Covenants of APP

            APP agrees that between the date hereof and the Closing:

            Section 8.1 Consummation of Agreement. APP will take all action
reasonably necessary to cause the consummation of the transactions contemplated
hereby in accordance with their terms and conditions and take all corporate and
other action necessary to approve the Merger; provided, however, that this
covenant shall not require APP to make any expenditures that are not expressly
set forth in this Agreement or otherwise contemplated herein.



                                       30

<PAGE>   37

            Section 8.2 Requirements to Effect the Merger and Acquisitions. APP
will use its best efforts to take, or cause to be taken, all actions necessary
to effect the Merger under applicable law, including without limitation the
filing with the appropriate government officials of all necessary documents in
form approved by counsel for the parties to this Agreement.

            Section 8.3 Access. APP shall, at reasonable times during normal
business hours and on reasonable notice, permit the Company and its authorized
representatives of the Company reasonable access to, and make available for
inspection, all of the assets and business of APP, including its executive
officers, and permit the Company and their authorized representatives to inspect
and, at the Company's sole expense, make copies of all documents, records and
information with respect to the affairs of APP as the Company and their
representatives may reasonably request, all for the sole purpose of permitting
the Company to become familiar with the business and assets and liabilities of
APP. No investigation by the Company or the Stockholders shall diminish or
otherwise affect any of the representations, warranties, covenants or agreements
of APP under this Agreement.

            Section 8.4 Notification of Certain Matters. APP shall promptly
inform the Company in writing of (a) any notice of, or other communication
relating to, a default or event that, with notice or lapse of time or both,
would become a default, received by APP subsequent to the date of this Agreement
and prior to the Effective Time under any contract, agreement or investment
material to APP's condition (financial or otherwise), operations, assets,
liabilities or business and to which it is subject; (b) any material adverse
change in APP's condition (financial or otherwise), operations, assets,
liabilities or business or (c) defaults or disputes regarding Other Agreements.

            Section 8.5 Qualified Retirement Plans. APP shall use its best
efforts to establish a qualified plan and trust for NewCo, within the meaning of
Section 401(a) and 501(a), respectively, of the Code ("New Qualified Plan") that
will provide benefits comparable (as determined under Section 401(a)(4) of the
Code) to the benefits provided under the qualified plans referenced in the
Disclosure Schedules, if any, sponsored by the Company as of March 31, 1997. APP
will file for a favorable determination letter from the IRS on the New Qualified
Plan and request a favorable determination from the IRS that NewCo is not a
member of an affiliated service group (as defined in Section 414(m) of the Code)
or a recipient organization of leased employee services (as defined in Section
414(n) of the Code). Any benefits provided under the New Qualified Plan shall be
conditioned on a favorable determination letter from the IRS. Costs associated
with the establishment and design of the New Qualified Plan shall be paid by
APP. The NewCo shall be responsible for funding any contributions to, or any
ongoing administrative costs of, the New Qualified Plan.

                                   ARTICLE IX

                        Covenants of APP and the Company

            APP and the Company agree as follows:

            Section 9.1 Filings; Other Action.

            (a) The Company shall cooperate with APP to promptly prepare and
file with the SEC the Registration Statements on Form S-1 and Form S-4 (or other
appropriate Forms) to be filed by APP in connection with its Initial Public
Offering and offering of the shares of APP Common Stock to the Target Interest
Holders pursuant to the transactions contemplated by this Agreement and the
Other Agreements (including the prospectus constituting parts thereof, the
"Registration Statements"). APP shall obtain all necessary state securities law
or "Blue Sky" permits and approvals required to carry out the transactions
contemplated by this Agreement. The Company shall cooperate with APP in the
preparation of the Registration Statements and shall furnish all information
concerning the Company and NewCo as may be reasonably requested in connection
with any such action in a timely manner.

            (b) The Company and APP and each separately represent and warrant
that (i) in the case of the Company, none of the written information or
documents supplied or to be supplied by it specifically



                                       31

<PAGE>   38

for inclusion in the Registration Statements, by exhibit or otherwise and (ii)
in the case of APP, will, at the time the Registration Statements and each
amendment and supplement thereto, if any, becomes effective under the Securities
Act, none of them contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The Company shall be entitled to review the Registration
Statements and each of the amendments thereto, if any, prior to the time each
becomes effective under the Securities Act. The Company shall have no
responsibility for information contained in the Registration Statements except
for information provided by the Company specifically for inclusion therein. The
Company's review of the Registration Statements shall not diminish or otherwise
affect the representations, covenants and warranties of APP contained in this
Agreement.

            (c) The Company shall, upon request, furnish APP with all
information concerning itself, its subsidiaries, directors, officers, partners,
Stockholders and NewCo, and such other matters as may be reasonably requested by
APP in connection with the preparation of the Registration Statements and each
of the amendments or supplements thereto, or any other statement, filing, notice
or application made by or on behalf of each such party or any of its
subsidiaries to any governmental entity in connection with the Merger and the
other transactions contemplated by this Agreement.

            Section 9.2 Amendments of Schedules. Each party hereto agrees that,
with respect to the representations and warranties of such party contained in
this Agreement, such party shall have the continuing obligation until the
Closing to supplement or amend promptly the Disclosure Schedules with respect to
any matter that would have been or would be required to be set forth or
described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on the Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Disclosure Schedule that constitutes or reflects a Material Adverse Effect on
APP may be made unless the Company consents to such amendment or supplement. For
purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 10.1 and 11.1 have been
fulfilled, the Disclosure Schedules hereto shall be deemed to be the Disclosure
Schedules as amended or supplemented pursuant to this Section 9.2. In the event
that the Company seeks to amend or supplement a Disclosure Schedule pursuant to
this Section 9.2 and APP does not consent to such amendment or supplement, or
APP seeks to amend or supplement a Disclosure Schedule pursuant to this Section
9.2, and the Company does not consent, this Agreement shall be deemed terminated
by mutual consent as set forth in Section 15.1(a) hereof.

            Section 9.3 Actions Contrary to Stated Intent. No party hereto will
knowingly, either before or after the Merger, take any action that would prevent
the Merger from qualifying as a tax-free exchange within the meaning of Sections
351 or 368 of the Code, as applicable.

            Section 9.4 Public Announcements. The parties hereto will consult
with each other before issuing any press release or making any public statement
with respect to this Agreement and the transactions contemplated hereby and,
except as may be required by applicable law, will not issue any such press
release or make any such public statement prior to such consultation, although
the foregoing shall not apply to any disclosure by APP in any filing with the
DOJ, FTC or SEC.

            Section 9.5 Expenses. Each party to this Agreement shall be solely
responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by the Company and NewCo in connection with the Merger
shall be paid by the Company Stockholders in full immediately prior to the
Closing and such expenses shall be the sole responsibility of the Stockholders
following the Closing Date and not APP.

            Section 9.6 Patient Confidentiality. APP shall agree to keep all
records and information regarding the patients of the Company and NewCo
confidential in accordance with all applicable laws.

Registration Statements with the SEC, and shall use its reasonable good faith
efforts to cause the Registration Statements to become effective under the
Securities Act and take any action required to be taken under the applicable
state Blue Sky or other securities laws in connection with the issuance of the
shares of APP Common Stock upon consummation of the Merger.

received by a Stockholder in the Merger (a "Reorganization").

records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Merger being treated as a Reorganization.
These obligations are excused as to a party required to maintain the books or
file a Tax Return if such party has provided to the other parties a written
opinion of competent tax counsel to the effect that there is not substantial
authority, within the meaning of Section 6662(d)(2)(B)(i) of the Code, to report
the Merger as a Reorganization and such opinion either is furnished prior to the
Effective Time or is based on facts or events not known at the Effective Time.
Each party shall provide to each other party such tax information, reports,
returns, or schedules as may be reasonably required to assist such party in
accounting for and reporting the Merger as a Reorganization.

            (c) The parties agree that no Stockholder shall be liable for any
taxes incurred by the Company and for which APP has successor liability therefor
which arise solely as a result of the Merger or the consummation of the
transactions contemplated hereby; provided that the foregoing shall not limit

or otherwise be deemed a waiver of any right of indemnification under Section
14.1 for a breach of any representation, warranty or covenant of the Company or
any Stockholder.

requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

                                   ARTICLE XIV

                                    Remedies

incurred by such individuals and/or entities arising out of or resulting from:

                    (a) a breach by the Company of any representation or
warranty (without giving effect to any Material Adverse Effect qualifier
contained as part of any such representation or warranty) or covenant of the
Company contained in this Agreement or in any Schedule or certificate delivered
thereunder;

                    (b) any violation (or alleged violation) by the Company

which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                    (c) any liability under the Securities Act, the Exchange Act
or any other federal or state "blue sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any (i) untrue statement
of material fact in any Registration Statement or any prospectus forming or part
thereof, or any amendment thereof or supplement thereto relating to the Company
(including any Company Subsidiary) or NewCo required to be stated therein or
(ii) failure to state information necessary to make the statements therein not
misleading, which untrue statement or failure to state information arises or
results solely from information provided in writing to APP or its counsel by the
Company or any Stockholder or their agents specifically for inclusion in any
such Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto.

            Section 14.2 Indemnification by APP. Subject to the terms and
conditions of this Article XIV, APP hereby agrees to indemnify, defend and hold
the Stockholders, the Company and NewCo and their respective directors,

harmless from and against all Damages asserted against or incurred by such
individuals and/or entities arising out of or resulting from:

                    (a) a breach by APP of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of APP contained in
this Agreement or in any schedule or certificate delivered hereunder; and

                    (b) any liability under the Securities Act, the Exchange Act
or any other federal or state "blue sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon



                                       38

<PAGE>   45

any untrue statements of material fact in any Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or required to be stated therein or failure to state information
necessary to make the statements therein not misleading (except for any
liability based upon any actual or alleged untrue statement of material fact or
an omission to state a material fact relating to NewCo, the Company or any
Stockholder which was derived from any information provided in writing by the
Company or a Company Subsidiary or any of their agents contained in the
representations and warranties set forth in this Agreement or any certificate,
exhibit, schedule or instrument required to be delivered under this Agreement.)

            Notwithstanding anything contained in either Sections 14.1 or 14.2
herein to the contrary, nothing contained in this Agreement shall relieve any of
the parties hereto of any liability or limit any liability that it may have in
the case of fraud in connection with the transactions contemplated by this
Agreement.

            Section 14.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                    (a) Any party claiming indemnification under the Agreement
(an "Indemnified Party") shall promptly (and, in the event, at least ten (10)
days prior to the due date for any responsive pleadings, filings or other
documents) (i) notify the party for whom indemnification is sought (the
"Indemnifying Party) of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying Party
a written notice ("Claim Notice") describing in reasonable detail the nature of
the Third Party Claim, a copy of all papers served with respect to such claim
(if any), an estimate of the amount of Damages attributable to the Third Party
Claim and the basis of the Indemnified Party's request for indemnification under
this Agreement. The failure to promptly deliver a Claim Notice shall not relieve
any Indemnifying Party of its obligations to any Indemnified Party with respect
to the related Third Party Claim except to the extent that the resulting delay
is materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (x) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article XIV
with respect to such Third Party Claim and (y) whether the Indemnifying Party
desires, at the sole cost and expense of such Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

                    (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may



                                       39

<PAGE>   46

employ separate counsel at the expense of the Indemnifying Party, and upon
written notification thereof, the Indemnifying Party shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Party shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                    (c) If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 14.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
14.3(b) but fails diligently and promptly to prosecute or settle the Third Party
Claim, then the Indemnified Party shall have the right to defend, at the sole
cost and expense of the Indemnifying Party (if the Indemnified Party is entitled
to indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to it that are different from or additional
to those available to the Indemnified Party, then the Indemnifying Party may
employ separate counsel and upon written notification thereof, the Indemnified
Party shall not have the right to assume the defense of such action on behalf of
the Indemnifying Party.

                    (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                    (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period



                                       40

<PAGE>   47

for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

                    (f) The Indemnifying Party shall provide the Indemnified
Party with written notice of any firm offer that is made to settle or compromise
a Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Party to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Party desired to accept such settlement.

                    (g) Notwithstanding any provision herein to the contrary,
the obligation of an Indemnifying Party to provide indemnification to an
Indemnified Party for breach of any representation or warranty as provided in
Sections 14.1(a) or 14.2(a) hereof shall not take effect unless and until the
Damages asserted against or incurred in the aggregate and on a collective basis
by the Indemnified Parties pursuant to either Section 14.1 or 14.2 (as
applicable) as a result of such a breach or breaches exceeds $100,000.

            Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

            Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of
any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

                                   ARTICLE XV

                                   Termination

            Section 15.1 Termination. This Agreement may be terminated and the
Merger and the Acquisitions may be abandoned:

                    (a) at any time prior to the Effective Date by mutual
agreement of all parties;

                    (b) at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and delivered
by the Company or any Stockholder pursuant to this Agreement is or becomes
untrue or breached in any material respect or if the Company or any Stockholder
fails to comply in any material respect with any material covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

                    (c) at any time prior to the Effective Date by the Company
if any representation or warranty of APP contained in this Agreement or in any
certificate or other document executed and delivered by APP pursuant to this
Agreement is or becomes untrue in any material respect of if APP fails to comply
in any material respect with any covenant or agreement contained herein, and any
such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

<PAGE>   48

                    (d) at any time prior to the Effective Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures, APP
deems termination to be advisable; or

                    (e) by APP or the Company if the Merger shall not have been
consummated by September 30, 1997.

            Section 15.2 Effect of Termination. Except as set forth in Section
16.3, in the event this Agreement is terminated pursuant to this Article XV,
this Agreement shall forthwith become void.

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

            Section 16.1 Non-Disclosure Covenant. The Company and NewCo
recognize and acknowledge that each has in the past, currently has, and in the
future may possibly have, access to certain Confidential Information of APP that
is valuable, special and a unique asset of such entity's business. APP
acknowledges that it had in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of the Company and
NewCo that is valuable, special and a unique asset of each such business. The
Company, NewCo and APP, severally, agree that they will not disclose such
Confidential Information to any person, firm, corporation, association or other
entity for any purpose or reason whatsoever, except (a) to authorized
representatives of APP, NewCo and the Company and (b) to counsel and other
advisers to APP, NewCo and the Company provided that such advisers (other than
counsel) agree to the confidentiality provisions of this Section 16.1, unless
(i) such information becomes available to or known by the public generally
through no fault of the Company, NewCo or APP, as the case may be, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii) the Company, NewCo or APP, as the case may be, shall, if
possible, give prior written notice thereof to the Company, NewCo or APP and
provide the Company or APP with the opportunity to contest such disclosure,
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, or
(iv) the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Merger or otherwise. In the event of a breach or
threatened breach by the Company, on the one hand, and APP, on the other hand,
of the provisions of this Section, APP, NewCo and the Company shall be entitled
to an injunction restraining the other party, as the case may be, from
disclosing, in whole or in part, such Confidential Information. Nothing herein
shall be construed as prohibiting any of such parties from pursuing any other
available remedy for such breach or threatened breach, including the recovery of
damages.

            Section 16.2 Damages. Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, NewCo and the Company agree that,
in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

            Section 16.3 Survival. The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                  Miscellaneous

            Section 17.1 Amendment; Waivers. This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto. Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto. The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

            Section 17.2 Assignment. Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any party hereto, except
by APP to a wholly owned subsidiary of APP; provided that any such assignment

            Section 17.3 Parties in Interest; No Third Party Beneficiaries.

shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. APP acknowledges

from APP against Damages incurred by the Stockholders resulting from a breach by
APP of any representation, warranty or covenant of APP contained herein. Except
as provided in the preceding sentence or as otherwise provided herein, neither

contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,

subject matter hereof.

            Section 17.5 Severability. If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws

this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

            Section 17.6 Survival of Representations, Warranties and Covenants.
The representations, warranties and covenants contained herein shall survive the
Closing and all statements contained in any certificate, exhibit or other
instrument delivered by or on behalf of the Company, any Stockholder or APP
pursuant to this Agreement shall be deemed to have been representations and
warranties by the Company, such Stockholder and APP. Notwithstanding any
provision in this Agreement to the contrary, the representations and warranties
contained herein shall survive the Closing until the second anniversary of the
Closing Date except that (a) the representations and warranties set forth in
Section 3.21 with respect to environmental matters shall survive for a period of
ten (10) years, (b) the representations and warranties set forth in Section 3.30
with respect to tax matters shall survive until such time as the limitations
period has run for all tax periods ended prior to the Closing Date, (c) the
representations and warranties contained in Section 3.27 and Section 3.33 with
respect to healthcare matters shall survive for a period of six (6) years and
(d) solely for purposes of Section 14.1(c) and Section 14.2(c), and solely to
the extent that any party to be indemnified pursuant to such provisions actually
incurs liability under the Securities Act, the Exchange Act or any other federal
or state securities law, the representations and warranties set forth therein
shall survive until the expiration of any applicable limitations period.

            Section 17.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

        Section 3.12 Litigation and Claims. There are no claims, lawsuits,

investigations or inquiries pending or, to the knowledge of the Company,
threatened against, or affecting the Company, any Company Subsidiary, any
Stockholder, the Physician Employees or any other licensed professional or other
individual affiliated with the Company affecting or that would reasonably be
likely to affect the Company Common Stock or the operations, business condition,
(financial or otherwise), or results of operations of the Company which (i) if
successful, may, individually or in the aggregate, have a Material Adverse
Effect on the Company or (ii) could adversely affect the ability of the Company
or any Company Subsidiary to effect the transactions contemplated hereby, and to
the knowledge of the Company there is no basis for any such action or any state
of facts or occurrence of any event which would reasonably be likely to give
rise to the foregoing. There are no unsatisfied judgments against the Company or
any Company Subsidiary or any licensed professional or other individual
affiliated with the Company or any Company Subsidiary relating to services
provided on behalf of the Company or any Company Subsidiary or any consent
decrees to which any of the foregoing is subject. Each of the matters, if any,
set forth in this Section 3.12 is fully covered by policies of insurance of the
Company or any Company Subsidiary as in effect on the date hereof.

        Section 3.13 No Violation of Law. Neither the Company nor any Company
Subsidiary has been, nor shall be as of the Effective Time (by virtue of any
action, omission to act, contract to which it is a party or any occurrence or
state of facts whatsoever), in violation of any applicable local, state or
federal law, ordinance, regulation, order, injunction or decree, or any other
requirement of any governmental body, agency, authority or court binding on it,
or relating to its properties, assets or business or its advertising, sales or
pricing practices, except for violations which, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
the Company.

        Section 3.14 Lease Agreements. The Disclosure Schedules contain a true,
accurate and complete list of all the lease agreements and license agreements to
which the Company or any Company Subsidiary is a party and pursuant to which the
Company or any Company Subsidiary leases (whether as lessor or lessee) or
licenses (whether as licensor or licensee) any real or personal property related
to the operation of its business and which requires payments in excess of
$12,000 per year (the "Lease Agreements"). The Company has delivered to APP true
and complete copies of all of the Lease Agreements. Each Lease Agreement is
valid, effective and in full force in accordance with its terms, and there is
not under any such lease (i) any existing or claimed material default by the
Company or any Company Subsidiary (as applicable) or event of material default
or event which with notice or lapse of time, or both, would constitute a
material default by the Company or any Company Subsidiary (as applicable) and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Company, or, (ii) to the knowledge of the Company, any existing
material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party. To the knowledge of the
Company, there is no pending or threatened reassessment of any property covered
by the Lease Agreements. The Company or any Company Subsidiary will use
reasonable good faith efforts to obtain, prior to the Effective Time, the
consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver to
APP in writing such consents as are necessary to effect a valid and binding
transfer or assignment of the Company's or any Company Subsidiary's rights
thereunder. The Company has a good, clear, valid and enforceable leasehold
interest under each of the Lease Agreements. The Lease Agreements comply with
the exceptions to ownership interests and compensation arrangements set out in
42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952, and any similar applicable
state law safe harbor or other exemption provisions.

all of its properties and assets (real, personal and mixed, tangible and
intangible) and any rights or interests therein

which it purports to own including, without limitation, all the property and
assets reflected in the Company Current Financial Statements; and (ii) owns such
rights, interests, assets and property free and clear of all Encumbrances, title
defects or objections (except for taxes not yet due and payable). The personal
property presently used in connection with the operation of the business of the
Company and the Company Subsidiaries constitutes the necessary personal property
assets to continue operation of the Company and any Company Subsidiary.

        Section 3.16 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, the Company does not have any
direct or indirect indebtedness for borrowed money, including indebtedness by
way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

        Section 3.17  Contracts and Commitments.

               (a) The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health
maintenance organization, other managed care organization or other third-party
provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of
obligations of third parties requiring the Company to make, or setting forth
conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000 in
any fiscal year or $25,000 in the aggregate and that are not cancelable by
providing notice of sixty (60) days or less. All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is with
unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP of the assets and
properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP. In every instance where consent is necessary, the Company
shall, on or before the Closing Date, use reasonable good faith efforts to
obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts. Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. Notwithstanding the foregoing, the Company shall not transfer to APP
any contracts or agreements relating to the provision of professional medical
services or other such agreements and contracts that APP consents to in writing
to be transferred to NewCo in the Spin-off Transaction. No contract with a
health care provider or Payor has been materially amended or terminated within
the last twelve (12) months.

               (b) The Company (i) has not received notice of any plan or
intention of any other party to exercise any right to cancel or terminate any
contract, agreement or instrument required to be disclosed pursuant to Section
3.17(a), and to the knowledge of the Company there are no fact(s) that would
justify the exercise of such a right; and (ii) does not currently contemplate,
or have reason to believe any other Person currently contemplates, any amendment
or change to any such contract, agreement or instrument.

        Section 3.18 Employee Matters. The Company is not currently a party to
any employment contract (except for oral employment agreements which are
terminable at will), consulting or collective bargaining contracts, deferred
compensation, pension plan (as defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974, as amended, and all rules and
regulations from time to time promulgated thereunder ("ERISA")), profit sharing,
bonus, stock option, stock purchase or other nonqualified benefit or
compensation commitments, benefit plans, arrangements or plans (whether written
or oral), including all welfare plans (as defined in Section 3(1) of ERISA) of
or pertaining to the Company and any of its present or former employees, or any
predecessors in interest. As of April 30, 1997, the Company employed a
collective total of [___] part-time and [____] full-time employees. The
Disclosure Schedules list each employee of, or consultant to, the Company who
received combined salary, benefits (other than those offered generally to all
other employees) and bonuses for 1996 in excess of $50,000 or who is expected to
receive combined salary, benefits (other than those offered generally to all
other employees) and bonuses in 1997 in excess of $50,000. The Company is not
delinquent in payment to any of its employees or Physician Employees for wages,
salaries, bonuses or other direct compensation for any services performed for it
to the date hereof or amounts required to be reimbursed to such employees. Upon

Employment Opportunity Commission or any federal, state or local agency or court
against the Company. There have been no governmental audits of the equal
employment opportunity practices of the Company and, to the knowledge of the
Company, no basis for any such audit exists which, if conducted would result in
a Material Adverse Effect on the Company;

               (d) The Company is in material compliance with the Immigration

promulgated thereunder; and

likely to result, directly or indirectly, (including through any obligation of
indemnification or contribution), in any taxes, penalties or other liability to
APP or any of its Affiliates.

               (e) Claims and Litigation. No pending or, to the Company's

determination letter or ruling from the IRS for each of the Employee Benefit
Plans intended to be qualified within the meaning of Section 401(a) or 501(c)(9)
of the Code and/or tax-exempt within the meaning of Section 501(a) of the Code
and, to the best knowledge of the Company and each Stockholder, has been
continually qualified under the applicable Section of the Code since the

Plan described in Section 501(c)(9) of the Code, the assets of each such plan
are at least equal in value to the present value of accrued benefits, based upon
the most recent actuarial valuation as of a date no more than ninety (90) days
prior to the date hereof. The Disclosure Schedules

Plan which has been subject to Title IV of ERISA or Section 412 of the Code.

               (j) PBGC. No facts or circumstances are known to the Company that
would result in the imposition of liability against APP or any of its Affiliates
by the Pension Benefit Guaranty Corporation ("PBGC") as a result of any act or
omission by the Company or any member of a Controlled Group. No reportable event
(within the meaning of Section 4043 of ERISA) for which the notice requirement

subject to the requirements of Title IV of ERISA.

               (k) Retirees. The Company has no obligation or commitment to

Environmental Law that had, or would reasonably be likely to have, a Material
Adverse Effect on the Company. Neither the Company nor any Company Subsidiary
has engaged in any activity or failed to undertake any activity which action or

Company.

reports which have been prepared by, for or, to the knowledge of the Company,

        Section 3.23 Insurance Policies. The Disclosure Schedules list and
briefly describe the Company's policies of insurance to which the Company or any
Company Subsidiary is a party or under which the Company or any Company
Subsidiary, officer or director thereof is or has been covered at any time
during the last five (5) years preceding the date of this Agreement relating to
the business of the Company or any Company Subsidiary (the "Insurance
Policies"). All of the Insurance Policies are valid, outstanding and enforceable
policies, except as may be limited by applicable bankruptcy, insolvency or
similar laws affecting creditors' rights generally or the availability of
equitable remedies and all premiums with respect thereto which are due and
payable are currently paid. All Insurance Policies currently maintained by the

the Company and its Affiliates for all risks normally insured against by a
Person carrying on a substantially similar business or businesses as the Company

Company Subsidiary nor any officer or director thereof has received any notice
or other written communication from any issuer of any Current Policy cancelling
such policy, materially increasing any deductibles or retained amounts
thereunder, or materially increasing the annual or other premiums payable
thereunder and, to the knowledge of the Company, no such cancellation or
increase of deductibles, retainages or premiums is threatened. There are no
outstanding claims, settlements or premiums owed against any Insurance Policy,
and all required notices have been given and all known potential or actual
claims under any Insurance Policy have been presented in due and timely fashion.
Within the five (5) years preceding the Agreement, neither the Company nor any
Company Subsidiary has filed a written application for any professional
liability insurance coverage which has been denied by an insurance agency or
carrier. The Disclosure Schedules also set forth a list of all claims under any
Insurance Policy in excess of $10,000 per occurrence filed by the Company or any
Company Subsidiary during the immediately preceding three-year period. Each
Physician Employee has, at all times while a Physician Employee, maintained or
been covered by professional malpractice insurance in such types and amounts as
are customary for such a physician practicing the same type of medicine in the
same geographic area.

        Section 3.24  Accounts Receivable; Payors.

               (a) The Disclosure Schedules set forth a list and aging of all
accounts receivable of the Company as of March 31, 1997, which list is complete,
true and accurate in all material respects. All such accounts receivable arose
in the ordinary course of business and have not been previously written off as
bad debts and, are, to the extent still uncollected, to the knowledge of the
Company collectible in the ordinary course of business, net of reserves for
doubtful and uncollectible accounts shown in the Company Financial Statements or
on the accounting records of the Company (which reserves are calculated
consistent with generally accepted accounting principles and past practice).

               (b) The Disclosure Schedules set forth (i) a true, correct and
complete list of the names and addresses of each Payor of the Company as of such
date, which accounted for more than 5% of the revenues of the Company in the
fiscal year ended December 31, 1996, or which is reasonably expected to account
for more than 5% of the revenues of the Company for the fiscal year to end

with a malpractice or similar action.

review organization, accrediting organization or certifying agency

        Section 5.1 Organization and Good Standing; Qualification. NewCo is a
professional corporation duly organized, validly existing and in good standing
under the laws of its state of organization, with all requisite corporate power
and authority to carry on the business in which it intends to engage, to own the

the Security Agreement and the Physician Employment Agreements and consummate
the transactions and perform the services contemplated thereby. NewCo is duly
qualified and licensed to do business and is in good standing in all

consists of [_____] shares of NewCo Common Stock, of which [______] shares are
issued and outstanding, and no shares of capital stock of NewCo are held in

performance by NewCo of the Service Agreement, the Security Agreement, the
Physician Employment Agreements and the other agreements contemplated thereby,

thereby, have been duly authorized by the Board of Directors of NewCo. The
Service Agreement, the Security Agreement, the Physician Employment Agreements
and each other agreement contemplated thereby will be as of the Closing Date
duly executed and delivered by NewCo and will constitute valid and binding
obligations of NewCo enforceable against NewCo in accordance with their
respective terms, except as may be limited by applicable bankruptcy, or other
laws affecting creditors' rights generally, or by general equity principles, or
by public policy.

        Section 5.5 No Violation. Neither the execution, delivery or performance
of the Service Agreement, the Security Agreement, the Physician Employment
Agreements or the other agreements contemplated thereby nor the consummation of

of, or constitute a default under, the articles or certificate of incorporation
or bylaws of NewCo, or (b) violate or conflict with any applicable local, state
or federal law, ordinance, regulation, order, injunction or decree, or any other
requirement of any governmental body, agency or authority or court binding on

might have any liability whatsoever arising from any tax-qualified plan as
required under applicable law. The Company acknowledges that the purpose and
intent of this covenant is to assure that APP shall have no liability whatsoever
at any time after the Closing Date with respect to any such tax-qualified plan,

incorporate NewCo in the state of New York, and the articles or certificate of

Prior to the Closing, the Company shall transfer to NewCo good, valid and
marketable title to all of the Company's right, title and interest in and to the
Employee Benefit Plans, all contracts and agreements and other assets listed on
the Disclosure Schedules (to be delivered by the Company prior to Closing, which
schedule will be subject to the approval of APP, which approval shall not be
unreasonably withheld) which by law either cannot be acquired or cannot be used
by APP because they relate to the practice of medicine or radiology, and shall
contribute to NewCo such other consideration and assets of the Company as may be
required under applicable law, in exchange for the issuance by NewCo of shares
of NewCo Common Stock, such shares being all of the issued and outstanding

The Company shall prepare and execute all documents necessary to effectuate the
"F" Reorganization prior to the Closing. At or prior to the Closing, the Company
shall cause an amendment to this Agreement to be executed which will reflect the
changes which result from the "F" Reorganization.

for inclusion in the Registration Statements, by exhibit or otherwise and (ii)
in the case of APP, will, at the time the Registration Statements and each
amendment and supplement thereto, if any, becomes effective under the Securities
Act, none of them contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The Company shall be entitled to review the Registration
Statements and each of the amendments thereto, if any, prior to the time each
becomes effective under the Securities Act. The Company shall have no
responsibility for information contained in the Registration Statements except
for information provided by the Company specifically for inclusion therein. The
Company's review of the Registration Statements shall not diminish or otherwise
affect the representations, covenants and warranties of APP contained in this
Agreement.

        (c) The Company shall, upon request, furnish APP with all information

supplement or amend promptly the Disclosure Schedules with respect to any matter
that would have been or would be required to be set forth or described in the
Disclosure Schedules in order to not materially breach any representation,
warranty or covenant of such party contained herein; provided that no amendment
or supplement to a Disclosure Schedule that constitutes or reflects a Material
Adverse Effect on the Company may be made unless APP consents to such amendment
or supplement, and no amendment or supplement to a Disclosure Schedule that
constitutes or reflects a Material Adverse Effect on APP may be made unless the
Company consents to such amendment or supplement. For purposes of this
Agreement, including without limitation for purposes of determining whether the
conditions set forth in Sections 10.1 and 11.1 have been fulfilled, the
Disclosure Schedules hereto shall be deemed to be the Disclosure Schedules as
amended or supplemented pursuant to this Section 9.2. In the event that the
Company seeks to amend or supplement a Disclosure Schedule pursuant to this
Section 9.2 and APP does not consent to such amendment or supplement, or APP
seeks to amend or supplement a Disclosure Schedule pursuant to this Section 9.2,
and the Company does not consent, this Agreement shall be deemed terminated by
mutual consent as set forth in Section 15.1(a) hereof.

        Section 9.3 Actions Contrary to Stated Intent. No party hereto will

        Section 9.4 Public Announcements. The parties hereto will consult with
each other before issuing any press release or making any public statement with
respect to this Agreement and the transactions contemplated hereby and, except

make any such public statement prior to such consultation, although the
foregoing shall not apply to any disclosure by APP in any filing with the DOJ,
FTC or SEC.

        Section 9.5 Expenses. Each party to this Agreement shall be solely
responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by the Company and NewCo in connection with the Merger
shall be paid by the Company Stockholders in full immediately prior to the
Closing and such expenses shall be the sole responsibility of the Stockholders
following the Closing Date and not APP.

        Section 9.6 Patient Confidentiality. APP shall agree to keep all records
and information regarding the patients of the Company and NewCo confidential in
accordance with all applicable laws.

any untrue statements of material fact in any Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or required to be stated therein or failure to state information
necessary to make the statements therein not misleading (except for any
liability based upon any actual or alleged untrue statement of material fact or
an omission to state a material fact relating to NewCo, the Company or any
Stockholder which was derived from any information provided in writing by the
Company or a Company Subsidiary or any of their agents contained in the
representations and warranties set forth in this Agreement or any certificate,
exhibit, schedule or instrument required to be delivered under this Agreement.)

               Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

        Section 14.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

               (a) Any party claiming indemnification under the Agreement (an
"Indemnified Party") shall promptly (and, in the event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party for whom indemnification is sought (the "Indemnifying
Party) of any third-party claim or claims asserted against the Indemnified Party
("Third Party Claim") that could give rise to a right of indemnification under
this Agreement and (ii) transmit to the Indemnifying Party a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of Damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement. The failure to promptly deliver a Claim Notice shall not relieve any
Indemnifying Party of its obligations to any Indemnified Party with respect to
the related Third Party Claim except to the extent that the resulting delay is
materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (x) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article XIV
with respect to such Third Party Claim and (y) whether the Indemnifying Party
desires, at the sole cost and expense of such Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

               (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may

<PAGE>   46


employ separate counsel at the expense of the Indemnifying Party, and upon
written notification thereof, the Indemnifying Party shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Party shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

               (c) If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to it that are different from or additional
to those available to the Indemnified Party, then the Indemnifying Party may
employ separate counsel and upon written notification thereof, the Indemnified
Party shall not have the right to assume the defense of such action on behalf of
the Indemnifying Party.

               (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

               (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period

                                       40
                                     

<PAGE>   47


for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

               (f) The Indemnifying Party shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Party to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Party desired to accept such settlement.

               (g) Notwithstanding any provision herein to the contrary, the
obligation of an Indemnifying Party to provide indemnification to an Indemnified
Party for breach of any representation or warranty as provided in Sections
14.1(a) or 14.2(a) hereof shall not take effect unless and until the Damages
asserted against or incurred in the aggregate and on a collective basis by the
Indemnified Parties pursuant to either Section 14.1 or 14.2 (as applicable) as a
result of such a breach or breaches exceeds $100,000.

        Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

        Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.

                                   Termination

        Section 15.1 Termination. This Agreement may be terminated and the
Merger and the Acquisitions may be abandoned:

               (a) at any time prior to the Effective Date by mutual agreement 
of all parties;

               (b) at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and delivered
by the Company or any Stockholder pursuant to this Agreement is or becomes
untrue or breached in any material respect or if the Company or any Stockholder
fails to comply in any material respect with any material covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

               (c) at any time prior to the Effective Date by the Company if any
representation or warranty of APP contained in this Agreement or in any
certificate or other document executed and delivered by APP pursuant to this
Agreement is or becomes untrue in any material respect of if APP fails to comply
in any material respect with any covenant or agreement contained herein, and any
such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

<PAGE>   48


               (d) at any time prior to the Effective Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures, APP
deems termination to be advisable; or

               (e) by APP or the Company if the Merger shall not have been
consummated by September 30, 1997.

        Section 15.2 Effect of Termination. Except as set forth in Section 16.3,
in the event this Agreement is terminated pursuant to this Article XV, this
Agreement shall forthwith become void.

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

        Section 16.1 Non-Disclosure Covenant. The Company and NewCo recognize
and acknowledge that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP that is
valuable, special and a unique asset of such entity's business. APP acknowledges
that it had in the past, currently has, and in the future may possibly have,
access to certain Confidential Information of the Company and NewCo that is
valuable, special and a unique asset of each such business. The Company, NewCo
and APP, severally, agree that they will not disclose such Confidential
Information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
APP, NewCo and the Company and (b) to counsel and other advisers to APP, NewCo
and the Company provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 16.1, unless (i) such information
becomes available to or known by the public generally through no fault of the
Company, NewCo or APP, as the case may be, (ii) disclosure is required by law or
the order of any governmental authority under color of law, provided, that prior
to disclosing any information pursuant to this clause (ii) the Company, NewCo or
APP, as the case may be, shall, if possible, give prior written notice thereof
to the Company, NewCo or APP and provide the Company or APP with the opportunity
to contest such disclosure, (iii) the disclosing party reasonably believes that
such disclosure is required in connection with the defense of a lawsuit against
the disclosing party, or (iv) the disclosing party is the sole and exclusive
owner of such Confidential Information as a result of the Merger or otherwise.
In the event of a breach or threatened breach by the Company, on the one hand,
and APP, on the other hand, of the provisions of this Section, APP, NewCo and
the Company shall be entitled to an injunction restraining the other party, as
the case may be, from disclosing, in whole or in part, such Confidential
Information. Nothing herein shall be construed as prohibiting any of such
parties from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages.

        Section 16.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, NewCo and the Company agree that, in the event of
a breach by either of them of the foregoing covenant, the covenant may be
enforced against them by injunctions and restraining orders.

        Section 16.3 Survival. The obligations of the parties under this Article
XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                  Miscellaneous

        Section 17.1 Amendment; Waivers. This Agreement may be amended, modified
or supplemented only by an instrument in writing executed by all the parties
hereto. Any waiver of any terms and conditions hereof must be in writing, and
signed by the parties hereto. The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

hereby or in any agreement entered into in connection with the transactions
contemplated hereby shall be assignable by any party hereto, except by APP to a
wholly owned subsidiary of APP; provided that any such assignment shall not
relieve APP of its obligations hereunder.

as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. APP acknowledges
and agrees that the rights and remedies of the Company under this Agreement will

rights and remedies of the Company under this Agreement, including, without
limitation, the rights and remedies under Article 14 hereof to indemnification
from APP against Damages incurred by the Stockholders resulting from a breach by
APP of any representation, warranty or covenant of APP contained herein. Except
as provided in the preceding sentence or as otherwise provided herein, neither

confer upon any person not a party hereto or thereto any rights or remedies
hereunder or thereunder.

        Section 17.4 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

        Section 17.5 Severability. If any provision of this Agreement is held to
be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

        Section 17.6 Survival of Representations, Warranties and Covenants. The
representations, warranties and covenants contained herein shall survive the
Closing and all statements contained in any certificate, exhibit or other
instrument delivered by or on behalf of the Company, any Stockholder or APP
pursuant to this Agreement shall be deemed to have been representations and
warranties by the Company, such Stockholder and APP. Notwithstanding any
provision in this Agreement to the contrary, the representations and warranties
contained herein shall survive the Closing until the second anniversary of the
Closing Date except that (a) the representations and warranties set forth in
Section 3.21 with respect to environmental matters shall survive for a period of
ten (10) years, (b) the representations and warranties set forth in Section 3.30
with respect to tax matters shall survive until such time as the limitations
period has run for all tax periods ended prior to the Closing Date, (c) the
representations and warranties contained in Section 3.27 and Section 3.33 with
respect to healthcare matters shall survive for a period of six (6) years and
(d) solely for purposes of Section 14.1(c) and Section 14.2(c), and solely to
the extent that any party to be indemnified pursuant to such provisions actually
incurs liability under the Securities Act, the Exchange Act or any other federal
or state securities law, the representations and warranties set forth therein
shall survive until the expiration of any applicable limitations period.

        Section 17.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

        Section 17.8 Captions. The captions in this Agreement are for

shall keep this Agreement and its terms confidential, and shall make no press
release or public disclosure, either written or oral, regarding the transactions

Dealers, (b) to attorneys, accountants, investment bankers or other agents of

(except by written instrument pursuant to Section 17.1 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default in or breach of any of the terms

or certificates (or completion of appropriate affidavit of lost certificate and
indemnity) receive such allocation of Merger Consideration as determined in
accordance with the provisions of Exhibit B attached hereto; and (ii) until each

surrendered by the Stockholders, the certificates for Company Common Stock
shall, for all purposes, represent solely the right to receive Merger

attached hereto and Section 2.10 hereof, if applicable. At the Effective Time,
each share of Company Common Stock converted into Merger Consideration shall by
virtue of the Merger and without any action on the part of the holders thereof,
cease to be outstanding, be cancelled and returned and all shares of APP Common
Stock issuable to the Stockholders in the Merger as part of the Merger

herein, no fractional shares of APP Common Stock will be issued and any
Stockholder otherwise entitled to receive a fractional share of APP Common Stock
as part of the Merger Consideration hereunder shall receive a cash payment in
lieu thereof reflecting such Stockholder's proportionate interest in a share of
APP Common Stock multiplied by the Initial Public Offering Price.

Company is a corporation duly organized, validly existing and in good standing
under the laws of its state of incorporation, with all requisite corporate power
and authority to own, operate and lease its assets and properties and to carry
on its business as currently conducted. The Company and each Company Subsidiary
is in good standing in each jurisdiction where the character of the property
owned or leased by it or the nature of its activities makes such qualification
necessary, except where such failure to be so qualified or in good standing
would not have a Material Adverse Effect on the Company. Copies of the articles
or certificates of incorporation and all amendments thereto of the Company and
each Company Subsidiary and the bylaws of the Company and each Company
Subsidiary, as amended, and copies of the corporate minutes of the Company, all
of which have been or will be made available to APP for review, are true and
complete as in effect on the date of this Agreement, and in the case of the
corporate minutes, accurately reflect all material proceedings of the
Stockholders and directors of the Company (and all committees thereof). The
stock record books of the Company, which have been or will be made available to
APP for review, contain true, complete and accurate records of the stock

capital stock.

            Section 3.2 Authorization and Validity. The Company has all

herein, and the consummation by the Company of the transactions contemplated
hereby and thereby are within the Company's respective corporate powers and have
been duly authorized by all necessary action on the part of the Company's Board
of Directors. Subject to the approval of this Agreement and the Merger by the
Stockholders, this Agreement has been duly executed by the Company, and this
Agreement and all other agreements and obligations entered into and undertaken
in connection with the transactions contemplated hereby to which the Company is
a party constitute, or upon execution will constitute, valid and binding
agreements of the Company, enforceable against it in accordance with their
respective terms, except as enforceability may be limited by bankruptcy or other
laws affecting the enforcement of creditors' rights generally, or by general
equity principles, or by public policy.

            Section 3.3 Governmental Authorization. Other than complying with
the provisions of the applicable state corporate laws regarding the approval of
the Merger and the filing of the Certificates of Merger (as contemplated by
Section 2.3) and any other required documents related to the Merger, and other

any Hart-Scott-Rodino filing to be made by APP, if any), the execution, delivery
and performance by the Company of this Agreement and the agreements provided for
herein, and the consummation of the transactions contemplated hereby and thereby
by the Company require no action by or in respect of, or filing with, any
governmental body, agency, official or authority.

            Section 3.4 Capitalization. The authorized capital stock of the
Company consists of 200 shares of the Company Common Stock, of which 130 shares
are issued and outstanding. The Stockholders collectively are and will be

Encumbrances, in the respective amounts set forth in the Disclosure Schedules.
Each outstanding share of Company Common Stock has been legally and validly
issued and is fully paid and nonassessable, and was issued pursuant to a valid
exemption from registration under (i) the Securities Act of 1933, as amended,
and (ii) all applicable state securities laws. No shares of Company Common Stock
are owned by the Company in treasury. No shares of Company Common Stock have
been issued or disposed of in violation of any preemptive rights, rights of
first refusal or similar rights of any of the Stockholders. Other than Company
Common Stock, the Company has no securities, bonds, debentures, notes or other
obligations the holders of which have the right to vote (or are convertible into
or exercisable for securities having the right to vote) with the Stockholders on
any matter.

            Section 3.5 Transactions in Capital Stock. There exist no Company
Rights. The Company has no obligation (contingent or otherwise) to purchase,
redeem or otherwise acquire any of its equity securities or any interests

Subject to approval of this Agreement and the Merger by the Stockholders of the
Company, the execution, delivery and performance by the Company of this
Agreement and any other documents contemplated hereby (with or without the

any governmental or regulatory body or authority or any other third party except
for such consents, for which the failure to obtain would not result in a
Material Adverse Effect on the Company; (ii) will not conflict with or result in
a violation of any provision of the Company's articles or certificate of
incorporation or bylaws, (iii) will not conflict with, result in a violation of,

conflict, termination, breach or default, the occurrence of which would not
result in a Material Adverse Effect on the Company; and (v) except as

individual affiliated with the Company affecting or that would reasonably be
likely to affect the Company Common Stock or the operations, business condition,
(financial or otherwise), or results of operations of the Company which (i) if
successful, may, individually or in the aggregate, have a Material Adverse
Effect on the Company or (ii) could adversely affect the ability of the Company

of facts or occurrence of any event which would reasonably be likely to give
rise to the foregoing. There are no unsatisfied judgments against the Company or
any Company Subsidiary or any licensed professional or other individual
affiliated with the Company or any Company Subsidiary relating to services

decrees to which any of the foregoing is subject. Each of the matters, if any,

Company or any Company Subsidiary as in effect on the date hereof.

            Section 3.13 No Violation of Law. Neither the Company nor any

requirement of any governmental body, agency, authority or court binding on it,
or relating to its properties, assets or business or its advertising, sales or
pricing practices, except for violations which, individually or in the

the Company.

            Section 3.14 Lease Agreements. The Disclosure Schedules contain a
true, accurate and complete list of all the lease agreements and license
agreements to which the Company or any Company Subsidiary is a party and
pursuant to which the Company or any Company Subsidiary leases (whether as
lessor or lessee) or licenses (whether as licensor or licensee) any real or
personal property related to the operation of its business and which requires
payments in excess of $12,000 per year (the "Lease Agreements"). The Company has
delivered to APP true and complete copies of all of the Lease Agreements. Each
Lease Agreement is valid, effective and in full force in accordance with its
terms, and there is not under any such lease (i) any existing or claimed
material default by the Company or any Company Subsidiary (as applicable) or
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by the Company or any Company Subsidiary (as
applicable) and, individually or in the aggregate, may reasonably result in a
Material Adverse Effect on the Company, or, (ii) to the knowledge of the
Company, any existing material default by any other party under any of the Lease
Agreements or any event of material default or event which with notice or lapse
of time, or both, would constitute a material default by any such party. To the
knowledge of the Company, there is no pending or threatened reassessment of any
property covered by the Lease Agreements. The Company or any Company Subsidiary
will use reasonable good faith efforts to obtain, prior to the Effective Time,
the consent of each landlord or lessor whose consent is required to the
assignment of the Lease Agreements and will use reasonable good faith efforts to
deliver to APP in writing such consents as are necessary to effect a valid and
binding transfer or assignment of the Company's or any Company Subsidiary's
rights thereunder. The Company has a good, clear, valid and enforceable
leasehold interest under each of the Lease Agreements. The Lease Agreements
comply with the exceptions to ownership interests and compensation arrangements
set out in 42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952, and any similar
applicable state law safe harbor or other exemption provisions.

interest (other than the Lease Agreements) in real property.

title to all of its properties and assets (real, personal and mixed, tangible
and intangible) and any rights or interests therein



                                       11

which it purports to own including, without limitation, all the property and
assets reflected in the Company Current Financial Statements; and (ii) owns such
rights, interests, assets and property free and clear of all Encumbrances, title
defects or objections (except for taxes not yet due and payable). The personal
property presently used in connection with the operation of the business of the
Company and the Company Subsidiaries constitutes the necessary personal property
assets to continue operation of the Company and any Company Subsidiary.

            Section 3.16 Indebtedness for Borrowed Money. Except for trade
payables incurred in the ordinary course of business, the Company does not have
any direct or indirect indebtedness for borrowed money, including indebtedness

manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

complete list, and the Company has delivered to APP true and complete copies, of

which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP of the assets and
properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP. In every instance where consent is necessary, the Company
shall, on or before the Closing Date, use reasonable good faith efforts to
obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts. Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. Notwithstanding the foregoing, the Company shall not transfer to APP
any contracts or agreements relating to the provision of professional medical
services or other such agreements and contracts that APP consents to in writing
to be transferred to NewCo in the Spin-off Transaction. No contract with a
health care provider or Payor has been materially amended or terminated within
the last twelve (12) months.

                    (b) Administration. Each Employee Benefit Plan has been

that any Employee Benefit Plan is currently the subject of an audit,
investigation, enforcement action or other similar proceeding conducted by any

reasonably likely to result, directly or indirectly, (including through any
obligation of indemnification or contribution), in any taxes, penalties or other
liability to APP or any of its Affiliates.

                    (e) Claims and Litigation. No pending or, to the Company's

and, to the best knowledge of the Company and each Stockholder, has been
continually qualified under the applicable Section of the Code since the
effective date of such Employee Benefit Plan. No proceedings exist or, to the
Company's knowledge, have been threatened that could result in the revocation of
any such favorable determination letter or ruling.

                    (g) Funding Status. No accumulated funding deficiency
(within the meaning of Section 412 of the Code), whether waived or unwaived,

determined on an ongoing basis as of the date hereof. With respect to each
Employee Benefit Plan described in Section 501(c)(9) of the Code, the assets of
each such plan are at least equal in value to the present value of accrued
benefits, based upon the most recent actuarial valuation as of a date no more
than ninety (90) days prior to the date hereof. The Disclosure Schedules

to determine the present value of accrued benefits under all Employee Benefit
Plans subject to actuarial assumptions.

Employee Benefit Plan which has been subject to Title IV of ERISA or Section 412
of the Code.

                    (j) PBGC. No facts or circumstances are known to the Company
that would result in the imposition of liability against APP or any of its
Affiliates by the Pension Benefit Guaranty Corporation ("PBGC") as a result of
any act or omission by the Company or any member of a Controlled Group. No
reportable event (within the meaning of Section 4043 of ERISA) for which the

Benefit Plan subject to the requirements of Title IV of ERISA.

                    (k) Retirees. The Company has no obligation or commitment to

                    (l) Other Compensation Arrangements. Neither the Company
nor, to the Company's knowledge, any Stockholder or Physician Employee is a
party to any compensation or debt arrangement with any Person relating to the

would be reasonably likely to give rise to any Environmental Liabilities (as
defined in subsection (e) below) for the Company under any applicable
Environmental Law that had, or would reasonably be likely to have, a Material
Adverse Effect on the Company. Neither the Company nor any Company Subsidiary
has engaged in any activity or failed to undertake any activity which action or
failure to act has given, or would reasonably be likely to give, rise to any
Environmental Liabilities or enforcement action by any federal, state or local
regulatory agency or authority, or has resulted, or would reasonably be likely
to result, in any fine or penalty imposed pursuant to any Environmental Law.

Company.

                    (d) There have been no environmental audits and other
similar reports which have been prepared by, for or, to the knowledge of the

end December 31, 1997, and (ii) a single line item listing for all private-pay
patients in the aggregate of the Company. The Company has satisfactory relations
with such Payors set forth in (i) above and none of such Payors has notified the

party.

for a dollar volume of purchases paid for by the Company in excess of $25,000
for the fiscal year to end December 31, 1997.

quality and a quantity usable and saleable in the ordinary course of the
Company's business and conform to generally accepted standards in the industry
of which the Company is a part. The value of the inventories reflected on the
Company Current Balance Sheet contained in the Company Financial Statements are
net of adequate reserves for damaged, excess, and unusable items. Purchase
commitments of the Company for inventory



                                       17

are not materially in excess of normal requirements, and none of such purchase
commitments are at prices in excess of prevailing market prices at the time of
such purchase commitment.

            Section 3.27 Licenses, Authorization and Provider Programs.

                    (a) The Company, and each Physician Employee and other
licensed employee or independent contractor of the Company (i) is the holder of

("Governmental Programs"). The Company, the Stockholders, and each Physician
Employee has a current provider number for such Governmental Programs and with
such private non-governmental programs (including without limitation any private
insurance program) under which the Company is presently receiving payments
directly or indirectly from any Payor for patient care provided by such
Physician Employee, licensed employee or independent contractor (such

Security Act), and provider agreements, is set forth in the Disclosure
Schedules, true, complete and correct copies of which have been provided to APP.
No violation, default, order or deficiency exists with respect to any of the
items listed in the Disclosure Schedules except for such violations, defaults,
orders or deficiencies which would not be reasonably likely to have a Material
Adverse Effect on the Company, and there is no action pending or to the
Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program, and
no event has occurred which, with or without notice or lapse of time, or both,
would constitute grounds for a violation, order or deficiency with respect to
any of the items listed in the Disclosure Schedules to revoke, withdraw or
suspend any material license to operate its business as is presently being
conducted by it. To the knowledge of the Company, there has been no decision not
to renew any existing agreement with any provider or Payor relating to the
Company's business as presently being conducted by it. Neither the Company nor
any Physician Employee (i) has had his/her/its professional license, Drug

settlement entered against him/her/it in connection with a malpractice or
similar action.

                    (b) The Company is not required, or for the 72-month period
prior to the Effective Time was not required, to file any cost reports or other
reports with any Governmental Program or Private Program.

the Company, or any Physician Employee, nor the right of any licensed
professional or other individual affiliated with the Company to receive
reimbursements pursuant to any Governmental Program or Private Program has been
terminated or otherwise materially and adversely affected as a result of any
investigation or action whether by any federal or state governmental regulatory
authority or other third party. No Physician Employee, licensed professional or
other individual affiliated with the business has, during the past three (3)
years prior to the Effective Time, had their professional license or staff
privileges limited, suspended or revoked by any governmental regulatory
authority or agency, hospital, integrated delivery system, trade association,
professional review organization, accrediting organization or certifying agency

            Section 7.8 Stockholders' Consent. The Company shall use its best
efforts to obtain the unanimous approval of its Stockholders to the Merger. In
seeking the approval of its Stockholders, the Company shall provide each
Stockholder with the Form S-4 which shall include information as may be required
by applicable law or as APP shall deem appropriate. The Board of Directors of
the Company shall recommend the approval of the Merger by the Stockholders of
the Company. If the Stockholders' approval is not unanimous, the Company shall
give notice to the nonconsenting Stockholders of the action taken by the
consenting Stockholders as may be required by applicable law.

            Section 7.9 Obligations of Company and Stockholders. Subject to
Section 7.8 hereof, the Company will take all action reasonably necessary to
cause the Company to perform its obligations under this Agreement and all
related agreements and to consummate the Merger and other transactions
contemplated hereby and thereby on the terms and conditions set forth in this
Agreement and such agreements; provided, however, that this covenant shall not
require the Company to make any expenditures that are not expressly set forth in
this Agreement or otherwise contemplated herein.

            Section 7.10 Funding of Accrued Employee Benefits. The Company
hereby covenants and agrees that it will take whatever steps are necessary to
pay for or fund completely any accrued benefits,



                                       29

<PAGE>   36

where applicable, or vested accrued benefits for which the Company or any entity
might have any liability whatsoever arising from any tax-qualified plan as
required under applicable law. The Company acknowledges that the purpose and
intent of this covenant is to assure that APP shall have no liability whatsoever
at any time after the Closing Date with respect to any such tax-qualified plan,
unless such plan is merged with a plan sponsored by APP.

            Section 7.11 Accounting and Tax Matters. The Company will not change
in any material respect the accounting methods or practices followed by the
Company (including any material change in any assumption underlying, or any
method of calculating, any bad debt, contingency or other reserve), except as
may be required by generally accepted accounting principles. The Company will
not make any material tax election except in the ordinary course of business
consistent with past practice, change any material tax election already made,
adopt any tax accounting method except in the ordinary course of business
consistent with past practice, change any tax accounting method, enter into any
closing agreement, settle any tax claim or assessment or consent to any tax
claim or assessment or any waiver of the statute of limitations for any such
claim or assessment. The Company will duly, accurately and timely (without
regard to any extensions of time) file all returns, information statements and
other documents relating to taxes of the Company required to be filed by it, and
pay all taxes required to be paid by it, on or before the Closing Date.

            Section 7.12 Spin-Off Transaction. The Company shall form, organize
and incorporate NewCo in the state of New York, and the articles or certificate
of incorporation and bylaws of NewCo shall be in form and substance reasonably
satisfactory to APP. Except for consummating the Spin-Off Transaction, NewCo
shall not commence business until the Closing Date. On or prior to the Closing,
the Company shall take all actions and execute all documents, agreements or
instruments necessary pursuant to and in compliance with applicable law to
effect the Spin-Off Transaction, including without limitation, the following:
Prior to the Closing, the Company shall transfer to NewCo good, valid and
marketable title to all of the Company's right, title and interest in and to the
Employee Benefit Plans, all contracts and agreements and other assets listed on
the Disclosure Schedules (to be delivered by the Company prior to Closing, which
schedule will be subject to the approval of APP, which approval shall not be
unreasonably withheld) which by law either cannot be acquired or cannot be used
by APP because they relate to the practice of medicine or radiology, and shall
contribute to NewCo such other consideration and assets of the Company as may be
required under applicable law, in exchange for the issuance by NewCo of shares
of NewCo Common Stock, such shares being all of the issued and outstanding
shares of NewCo Common Stock. The Company shall then distribute the shares of
NewCo Common Stock to the Stockholders in proportion to their respective
ownership interest in the Company.

            Section 7.13 "F" Reorganization. The Company shall convert its
corporate status from that of a professional medical corporation to that of a
general business corporation in a transaction which will qualify as a tax-free
transaction under Section 368(a)(2)(F) of the Code (the "F" Reorganization").
The Company shall prepare and execute all documents necessary to effectuate the
"F" Reorganization prior to the Closing. At or prior to the Closing, the Company
shall cause an amendment to this Agreement to be executed which will reflect the
changes which result from the "F" Reorganization.

reasonably necessary to cause the consummation of the transactions contemplated

set forth in this Agreement or otherwise contemplated herein.

            Section 8.2 Requirements to Effect the Merger and Acquisitions. APP
will use its best efforts to take, or cause to be taken, all actions necessary
to effect the Merger under applicable law, including without limitation the
filing with the appropriate government officials of all necessary documents in
form approved by counsel for the parties to this Agreement.

            Section 8.3 Access. APP shall, at reasonable times during normal
business hours and on reasonable notice, permit the Company and its authorized
representatives of the Company reasonable access to, and make available for

officers, and permit the Company and their authorized representatives to inspect
and, at the Company's sole expense, make copies of all documents, records and
information with respect to the affairs of APP as the Company and their
representatives may reasonably request, all for the sole purpose of permitting
the Company to become familiar with the business and assets and liabilities of
APP. No investigation by the Company or the Stockholders shall diminish or
otherwise affect any of the representations, warranties, covenants or agreements
of APP under this Agreement.

            Section 8.4 Notification of Certain Matters. APP shall promptly
inform the Company in writing of (a) any notice of, or other communication
relating to, a default or event that, with notice or lapse of time or both,
would become a default, received by APP subsequent to the date of this Agreement
and prior to the Effective Time under any contract, agreement or investment
material to APP's condition (financial or otherwise), operations, assets,
liabilities or business and to which it is subject; (b) any material adverse
change in APP's condition (financial or otherwise), operations, assets,
liabilities or business or (c) defaults or disputes regarding Other Agreements.

            Section 8.5 Qualified Retirement Plans. APP shall use its best
efforts to establish a qualified plan and trust for NewCo, within the meaning of
Section 401(a) and 501(a), respectively, of the Code ("New Qualified Plan") that
will provide benefits comparable (as determined under Section 401(a)(4) of the
Code) to the benefits provided under the qualified plans referenced in the
Disclosure Schedules, if any, sponsored by the Company as of March 31, 1997. APP
will file for a favorable determination letter from the IRS on the New Qualified
Plan and request a favorable determination from the IRS that NewCo is not a
member of an affiliated service group (as defined in Section 414(m) of the Code)
or a recipient organization of leased employee services (as defined in Section
414(n) of the Code). Any benefits provided under the New Qualified Plan shall be
conditioned on a favorable determination letter from the IRS. Costs associated
with the establishment and design of the New Qualified Plan shall be paid by
APP. The NewCo shall be responsible for funding any contributions to, or any
ongoing administrative costs of, the New Qualified Plan.

                        Covenants of APP and the Company

            APP and the Company agree as follows:

            Section 9.1 Filings; Other Action.

            (a) The Company shall cooperate with APP to promptly prepare and

appropriate Forms) to be filed by APP in connection with its Initial Public
Offering and offering of the shares of APP Common Stock to the Target Interest
Holders pursuant to the transactions contemplated by this Agreement and the
Other Agreements (including the prospectus constituting parts thereof, the

or "Blue Sky" permits and approvals required to carry out the transactions
contemplated by this Agreement. The Company shall cooperate with APP in the

concerning the Company and NewCo as may be reasonably requested in connection
with any such action in a timely manner.

            (b) The Company and APP and each separately represent and warrant
that (i) in the case of the Company, none of the written information or
documents supplied or to be supplied by it specifically



                                       31

<PAGE>   38

for inclusion in the Registration Statements, by exhibit or otherwise and (ii)
in the case of APP, will, at the time the Registration Statements and each
amendment and supplement thereto, if any, becomes effective under the Securities
Act, none of them contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The Company shall be entitled to review the Registration
Statements and each of the amendments thereto, if any, prior to the time each
becomes effective under the Securities Act. The Company shall have no
responsibility for information contained in the Registration Statements except
for information provided by the Company specifically for inclusion therein. The
Company's review of the Registration Statements shall not diminish or otherwise
affect the representations, covenants and warranties of APP contained in this
Agreement.

            (c) The Company shall, upon request, furnish APP with all
information concerning itself, its subsidiaries, directors, officers, partners,
Stockholders and NewCo, and such other matters as may be reasonably requested by
APP in connection with the preparation of the Registration Statements and each
of the amendments or supplements thereto, or any other statement, filing, notice
or application made by or on behalf of each such party or any of its
subsidiaries to any governmental entity in connection with the Merger and the
other transactions contemplated by this Agreement.

            Section 9.2 Amendments of Schedules. Each party hereto agrees that,
with respect to the representations and warranties of such party contained in
this Agreement, such party shall have the continuing obligation until the
Closing to supplement or amend promptly the Disclosure Schedules with respect to
any matter that would have been or would be required to be set forth or
described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on the Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Disclosure Schedule that constitutes or reflects a Material Adverse Effect on
APP may be made unless the Company consents to such amendment or supplement. For
purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 10.1 and 11.1 have been
fulfilled, the Disclosure Schedules hereto shall be deemed to be the Disclosure
Schedules as amended or supplemented pursuant to this Section 9.2. In the event
that the Company seeks to amend or supplement a Disclosure Schedule pursuant to
this Section 9.2 and APP does not consent to such amendment or supplement, or
APP seeks to amend or supplement a Disclosure Schedule pursuant to this Section
9.2, and the Company does not consent, this Agreement shall be deemed terminated
by mutual consent as set forth in Section 15.1(a) hereof.

            Section 9.3 Actions Contrary to Stated Intent. No party hereto will
knowingly, either before or after the Merger, take any action that would prevent
the Merger from qualifying as a tax-free exchange within the meaning of Sections
351 or 368 of the Code, as applicable.

            Section 9.4 Public Announcements. The parties hereto will consult
with each other before issuing any press release or making any public statement
with respect to this Agreement and the transactions contemplated hereby and,
except as may be required by applicable law, will not issue any such press
release or make any such public statement prior to such consultation, although
the foregoing shall not apply to any disclosure by APP in any filing with the
DOJ, FTC or SEC.

            Section 9.5 Expenses. Each party to this Agreement shall be solely
responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by the Company and NewCo in connection with the Merger
shall be paid by the Company Stockholders in full immediately prior to the
Closing and such expenses shall be the sole responsibility of the Stockholders
following the Closing Date and not APP.

            Section 9.6 Patient Confidentiality. APP shall agree to keep all
records and information regarding the patients of the Company and NewCo
confidential in accordance with all applicable laws.

shares of APP Common Stock upon consummation of the Merger.

recognize gain or loss, and pursuant to which any gain recognized by a
Stockholder as a result of the Merger will not exceed the amount of any cash
received by a Stockholder in the Merger (a "Reorganization").

            (b) Both prior to and after the Effective Time, all books and
records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Merger being treated as a Reorganization.
These obligations are excused as to a party required to maintain the books or
file a Tax Return if such party has provided to the other parties a written
opinion of competent tax counsel to the effect that there is not substantial
authority, within the meaning of Section 6662(d)(2)(B)(i) of the Code, to report
the Merger as a Reorganization and such opinion either is furnished prior to the
Effective Time or is based on facts or events not known at the Effective Time.
Each party shall provide to each other party such tax information, reports,
returns, or schedules as may be reasonably required to assist such party in
accounting for and reporting the Merger as a Reorganization.

            (c) The parties agree that no Stockholder shall be liable for any
taxes incurred by the Company and for which APP has successor liability therefor
which arise solely as a result of the Merger or the consummation of the
transactions contemplated hereby; provided that the foregoing shall not limit



                                       37

or otherwise be deemed a waiver of any right of indemnification under Section
14.1 for a breach of any representation, warranty or covenant of the Company or
any Stockholder.

            Section 13.3 Current Public Information. APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

                                   ARTICLE XIV

                                    Remedies

            Section 14.1 Indemnification by the Company. Subject to the terms
and conditions of this Article XIV, the Company agrees to indemnify, defend and
hold APP and its respective directors, officers, stockholders, employees,
agents, attorneys, consultants and Affiliates harmless from and against all
losses, claims, obligations, demands, assessments, penalties, liabilities,
costs, damages, reasonable attorneys' fees and expenses (including, without
limitation, all costs of experts and all costs incidental to or in connection
with any appellate process) (collectively, "Damages") asserted against or
incurred by such individuals and/or entities arising out of or resulting from:

                    (a) a breach by the Company of any representation or
warranty (without giving effect to any Material Adverse Effect qualifier
contained as part of any such representation or warranty) or covenant of the
Company contained in this Agreement or in any Schedule or certificate delivered
thereunder;

                    (b) any violation (or alleged violation) by the Company
and/or any of its past or present directors, officers, partners, stockholders,
employees (including, without limitation, any Physician Employee), agents,
attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons in
which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                    (c) any liability under the Securities Act, the Exchange Act
or any other federal or state "blue sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any (i) untrue statement
of material fact in any Registration Statement or any prospectus forming or part
thereof, or any amendment thereof or supplement thereto relating to the Company
(including any Company Subsidiary) or NewCo required to be stated therein or
(ii) failure to state information necessary to make the statements therein not
misleading, which untrue statement or failure to state information arises or
results solely from information provided in writing to APP or its counsel by the
Company or any Stockholder or their agents specifically for inclusion in any
such Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto.

            Section 14.2 Indemnification by APP. Subject to the terms and
conditions of this Article XIV, APP hereby agrees to indemnify, defend and hold
the Stockholders, the Company and NewCo and their respective directors,
officers, stockholders, employees, agents, attorneys, consultants and Affiliates
harmless from and against all Damages asserted against or incurred by such
individuals and/or entities arising out of or resulting from:

                    (a) a breach by APP of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of APP contained in
this Agreement or in any schedule or certificate delivered hereunder; and

                    (b) any liability under the Securities Act, the Exchange Act
or any other federal or state "blue sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon



                                       38

<PAGE>   45

any untrue statements of material fact in any Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or required to be stated therein or failure to state information
necessary to make the statements therein not misleading (except for any
liability based upon any actual or alleged untrue statement of material fact or
an omission to state a material fact relating to NewCo, the Company or any
Stockholder which was derived from any information provided in writing by the
Company or a Company Subsidiary or any of their agents contained in the
representations and warranties set forth in this Agreement or any certificate,
exhibit, schedule or instrument required to be delivered under this Agreement.)

            Notwithstanding anything contained in either Sections 14.1 or 14.2
herein to the contrary, nothing contained in this Agreement shall relieve any of
the parties hereto of any liability or limit any liability that it may have in
the case of fraud in connection with the transactions contemplated by this
Agreement.

            Section 14.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                    (a) Any party claiming indemnification under the Agreement
(an "Indemnified Party") shall promptly (and, in the event, at least ten (10)
days prior to the due date for any responsive pleadings, filings or other
documents) (i) notify the party for whom indemnification is sought (the
"Indemnifying Party) of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying Party
a written notice ("Claim Notice") describing in reasonable detail the nature of
the Third Party Claim, a copy of all papers served with respect to such claim
(if any), an estimate of the amount of Damages attributable to the Third Party
Claim and the basis of the Indemnified Party's request for indemnification under
this Agreement. The failure to promptly deliver a Claim Notice shall not relieve
any Indemnifying Party of its obligations to any Indemnified Party with respect
to the related Third Party Claim except to the extent that the resulting delay
is materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (x) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article XIV
with respect to such Third Party Claim and (y) whether the Indemnifying Party
desires, at the sole cost and expense of such Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

                    (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may



                                       39

<PAGE>   46

employ separate counsel at the expense of the Indemnifying Party, and upon
written notification thereof, the Indemnifying Party shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Party shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                    (c) If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 14.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
14.3(b) but fails diligently and promptly to prosecute or settle the Third Party
Claim, then the Indemnified Party shall have the right to defend, at the sole
cost and expense of the Indemnifying Party (if the Indemnified Party is entitled
to indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to it that are different from or additional
to those available to the Indemnified Party, then the Indemnifying Party may
employ separate counsel and upon written notification thereof, the Indemnified
Party shall not have the right to assume the defense of such action on behalf of
the Indemnifying Party.

                    (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                    (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period



                                       40

<PAGE>   47

for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

                    (f) The Indemnifying Party shall provide the Indemnified
Party with written notice of any firm offer that is made to settle or compromise
a Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Party to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Party desired to accept such settlement.

                    (g) Notwithstanding any provision herein to the contrary,
the obligation of an Indemnifying Party to provide indemnification to an
Indemnified Party for breach of any representation or warranty as provided in
Sections 14.1(a) or 14.2(a) hereof shall not take effect unless and until the

this Agreement shall forthwith become void.

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

            Section 16.1 Non-Disclosure Covenant. The Company and NewCo
recognize and acknowledge that each has in the past, currently has, and in the
future may possibly have, access to certain Confidential Information of APP that
is valuable, special and a unique asset of such entity's business. APP
acknowledges that it had in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of the Company and
NewCo that is valuable, special and a unique asset of each such business. The
Company, NewCo and APP, severally, agree that they will not disclose such
Confidential Information to any person, firm, corporation, association or other
entity for any purpose or reason whatsoever, except (a) to authorized
representatives of APP, NewCo and the Company and (b) to counsel and other
advisers to APP, NewCo and the Company provided that such advisers (other than
counsel) agree to the confidentiality provisions of this Section 16.1, unless
(i) such information becomes available to or known by the public generally
through no fault of the Company, NewCo or APP, as the case may be, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii) the Company, NewCo or APP, as the case may be, shall, if
possible, give prior written notice thereof to the Company, NewCo or APP and
provide the Company or APP with the opportunity to contest such disclosure,
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, or
(iv) the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Merger or otherwise. In the event of a breach or
threatened breach by the Company, on the one hand, and APP, on the other hand,
of the provisions of this Section, APP, NewCo and the Company shall be entitled
to an injunction restraining the other party, as the case may be, from
disclosing, in whole or in part, such Confidential Information. Nothing herein
shall be construed as prohibiting any of such parties from pursuing any other
available remedy for such breach or threatened breach, including the recovery of
damages.

            Section 16.2 Damages. Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, NewCo and the Company agree that,
in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

            Section 16.3 Survival. The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                  Miscellaneous

            Section 17.1 Amendment; Waivers. This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto. Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto. The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

unenforceable provision never comprised a part hereof; and the remaining

affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

            Section 17.6 Survival of Representations, Warranties and Covenants.
The representations, warranties and covenants contained herein shall survive the

warranties by the Company, such Stockholder and APP. Notwithstanding any
provision in this Agreement to the contrary, the representations and warranties

incurs liability under the Securities Act, the Exchange Act or any other federal
or state securities law, the representations and warranties set forth therein
shall survive until the expiration of any applicable limitations period.

            Section 17.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

         Section 3.12 Litigation and Claims. There are no claims, lawsuits,
actions, arbitrations, administrative or other proceedings, governmental
investigations or inquiries pending or, to the knowledge of the Company,
threatened against, or affecting the Company, any Company Subsidiary, any
Stockholder, the Physician Employees or any other licensed professional or other
individual affiliated with the Company affecting or that would reasonably be
likely to affect the Company Common Stock or the operations, business condition,
(financial or otherwise), or results of operations of the Company which (i) if
successful, may, individually or in the aggregate, have a Material Adverse
Effect on the Company or (ii) could adversely affect the ability of the Company
or any Company Subsidiary to effect the transactions contemplated hereby, and to
the knowledge of the Company there is no basis for any such action or any state
of facts or occurrence of any event which would reasonably be likely to give
rise to the foregoing. There are no unsatisfied judgments against the Company or
any Company Subsidiary or any licensed professional or other individual
affiliated with the Company or any Company Subsidiary relating to services
provided on behalf of the Company or any Company Subsidiary or any consent
decrees to which any of the foregoing is subject. Each of the matters, if any,
set forth in this Section 3.12 is fully covered by policies of insurance of the
Company or any Company Subsidiary as in effect on the date hereof.

         Section 3.13 No Violation of Law. Neither the Company nor any Company
Subsidiary has been, nor shall be as of the Effective Time (by virtue of any
action, omission to act, contract to which it is a party or any occurrence or

federal law, ordinance, regulation, order, injunction or decree, or any other
requirement of any governmental body, agency, authority or court binding on it,
or relating to its properties, assets or business or its advertising, sales or

Company or any Company Subsidiary leases (whether as lessor or lessee) or

to the operation of its business and which requires payments in excess of
$12,000 per year (the "Lease Agreements"). The Company has delivered to APP true
and complete copies of all of the Lease Agreements. Each Lease Agreement is
valid, effective and in full force in accordance with its terms, and there is
not under any such lease (i) any existing or claimed material default by the
Company or any Company Subsidiary (as applicable) or event of material default
or event which with notice or lapse of time, or both, would constitute a
material default by the Company or any Company Subsidiary (as applicable) and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Company, or, (ii) to the knowledge of the Company, any existing
material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party. To the knowledge of the
Company, there is no pending or threatened reassessment of any property covered
by the Lease Agreements. The Company or any Company Subsidiary will use
reasonable good faith efforts to obtain, prior to the Effective Time, the
consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver to
APP in writing such consents as are necessary to effect a valid and binding
transfer or assignment of the Company's or any Company Subsidiary's rights
thereunder. The Company has a good, clear, valid and enforceable leasehold
interest under each of the Lease Agreements. The Lease Agreements comply with
the exceptions to ownership interests and compensation arrangements set out in

state law safe harbor or other exemption provisions.

to all of its properties and assets (real, personal and mixed, tangible and
intangible) and any rights or interests therein


                                       11
<PAGE>   18
which it purports to own including, without limitation, all the property and
assets reflected in the Company Current Financial Statements; and (ii) owns such
rights, interests, assets and property free and clear of all Encumbrances, title
defects or objections (except for taxes not yet due and payable). The personal
property presently used in connection with the operation of the business of the
Company and the Company Subsidiaries constitutes the necessary personal property
assets to continue operation of the Company and any Company Subsidiary.

         Section 3.16 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, the Company does not have any

way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

         Section 3.17 Contracts and Commitments.

                  (a) The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health

provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of
obligations of third parties requiring the Company to make, or setting forth
conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000 in

other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is with
unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP of the assets and
properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP. In every instance where consent is necessary, the Company
shall, on or before the Closing Date, use reasonable good faith efforts to
obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts. Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. Notwithstanding the foregoing, the Company shall not transfer to APP
any contracts or agreements relating to the provision of professional medical
services or other such agreements and contracts that APP consents to in writing
to be transferred to NewCo in the Spin-off Transaction. No contract with a
health care provider or Payor has been materially amended or terminated within
the last twelve (12) months.

intention of any other party to exercise any right to cancel or terminate any
contract, agreement or instrument required to be disclosed pursuant to Section
3.17(a), and to the knowledge of the Company there are no fact(s) that would
justify the exercise of such a right; and (ii) does not currently contemplate,
or have reason to believe any other Person currently contemplates, any amendment
or change to any such contract, agreement or instrument.

         Section 3.18 Employee Matters. The Company is not currently a party to
any employment contract (except for oral employment agreements which are
terminable at will), consulting or collective bargaining contracts, deferred
compensation, pension plan (as defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974, as amended, and all rules and
regulations from time to time promulgated thereunder ("ERISA")), profit sharing,
bonus, stock option, stock purchase or other nonqualified benefit or
compensation commitments, benefit plans, arrangements or plans (whether written

predecessors in interest. As of April 30, 1997, the Company employed a
collective total of [___] part-time and [____] full-time employees. The

increase of deductibles, retainages or premiums is threatened. There are no
outstanding claims, settlements or premiums owed against any Insurance Policy,
and all required notices have been given and all known potential or actual
claims under any Insurance Policy have been presented in due and timely fashion.
Within the five (5) years preceding the Agreement, neither the Company nor any
Company Subsidiary has filed a written application for any professional
liability insurance coverage which has been denied by an insurance agency or

patients in the aggregate of the Company. The Company has satisfactory relations
with such Payors set forth in (i) above and none of such Payors has notified the

party.

quality and a quantity usable and saleable in the ordinary course of the
Company's business and conform to generally accepted standards in the industry
of which the Company is a part. The value of the inventories reflected on the
Company Current Balance Sheet contained in the Company Financial Statements are
net of adequate reserves for damaged, excess, and unusable items. Purchase
commitments of the Company for inventory


                                       17

("Governmental Programs"). The Company, the Stockholders, and each Physician
Employee has a current provider number for such Governmental Programs and with
such private non-governmental programs (including without limitation any private

items listed in the Disclosure Schedules except for such violations, defaults,
orders or deficiencies which would not be reasonably likely to have a Material
Adverse Effect on the Company, and there is no action pending or to the
Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program, and
no event has occurred which, with or without notice or lapse of time, or both,
would constitute grounds for a violation, order or deficiency with respect to
any of the items listed in the Disclosure Schedules to revoke, withdraw or
suspend any material license to operate its business as is presently being
conducted by it. To the knowledge of the Company, there has been no decision not
to renew any existing agreement with any provider or Payor relating to the

or other individual affiliated with the Company to receive reimbursements
pursuant to any Governmental Program or Private Program has been terminated or
otherwise materially and adversely affected as a result of any investigation or
action whether by any federal or state governmental regulatory authority or
other third party. No Physician Employee, licensed professional or other
individual affiliated with the business has, during the past three (3) years
prior to the Effective Time, had their professional license or staff privileges
limited, suspended or revoked by any governmental regulatory authority or
agency, hospital, integrated delivery system, trade association, professional
review organization, accrediting organization or certifying agency


                                       18

professional corporation duly organized, validly existing and in good standing
under the laws of its state of organization, with all requisite corporate power
and authority to carry on the business in which it intends to engage, to own the

the Security Agreement and the Physician Employment Agreements and consummate
the transactions and perform the services contemplated thereby. NewCo is duly
qualified and licensed to do business and is in good standing in all

where the failure to be so qualified shall not have a Material Adverse Effect on

obligations of NewCo enforceable against NewCo in accordance with their
respective terms, except as may be limited by applicable bankruptcy, or other
laws affecting creditors' rights generally, or by general equity principles, or

performance of the Service Agreement, the Security Agreement, the Physician
Employment Agreements or the other agreements contemplated thereby nor the

conditions or provisions of, or constitute a default under, the articles or
certificate of incorporation or bylaws of NewCo, or (b) violate or conflict with
any applicable local, state or federal law, ordinance, regulation, order,
injunction or decree, or any other requirement of any governmental body, agency
or authority or court binding on it, or relating to its property or business.

or pursuant to the Spin-Off Transaction, and NewCo does not have any
liabilities, accrued, contingent or otherwise (known or unknown and asserted or

intent of this covenant is to assure that APP shall have no liability whatsoever
at any time after the Closing Date with respect to any such tax-qualified plan,
unless such plan is merged with a plan sponsored by APP.

         Section 7.11 Accounting and Tax Matters. The Company will not change in
any material respect the accounting methods or practices followed by the Company

accounting method except in the ordinary course of business consistent with past
practice, change any tax accounting method, enter into any closing agreement,

the Disclosure Schedules (to be delivered by the Company prior to Closing, which
schedule will be subject to the approval of APP, which approval shall not be
unreasonably withheld) which by law either cannot be acquired or cannot be used
by APP because they relate to the practice of medicine or radiology, and shall
contribute to NewCo such other consideration and assets of the Company as may be
required under applicable law, in exchange for the issuance by NewCo of shares
of NewCo Common Stock, such shares being all of the issued and outstanding
shares of NewCo Common Stock. The Company shall then distribute the shares of
NewCo Common Stock to the Stockholders in proportion to their respective
ownership interest in the Company.

information with respect to the affairs of APP as the Company and their
representatives may reasonably request, all for the sole purpose of permitting
the Company to become familiar with the business and assets and liabilities of

of APP under this Agreement.

         Section 8.4 Notification of Certain Matters. APP shall promptly inform

provide benefits comparable (as determined under Section 401(a)(4) of the Code)
to the benefits provided under the qualified plans referenced in the Disclosure
Schedules, if any, sponsored by the Company as of March 31, 1997. APP will file
for a favorable determination letter from the IRS on the New Qualified Plan and
request a favorable determination from the IRS that NewCo is not a member of an
affiliated service group (as defined in Section 414(m) of the Code) or a
recipient organization of leased employee services (as defined in Section 414(n)
of the Code). Any benefits provided under the New Qualified Plan shall be
conditioned on a favorable determination letter from the IRS. Costs associated
with the establishment and design of the New Qualified Plan shall be paid by
APP. The NewCo shall be responsible for funding any contributions to, or any
ongoing administrative costs of, the New Qualified Plan.

other appropriate Forms) to be filed by APP in connection with its Initial

                  (b) The Company and APP and each separately represent and

<PAGE>   38
for inclusion in the Registration Statements, by exhibit or otherwise and (ii)
in the case of APP, will, at the time the Registration Statements and each
amendment and supplement thereto, if any, becomes effective under the Securities
Act, none of them contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The Company shall be entitled to review the Registration
Statements and each of the amendments thereto, if any, prior to the time each
becomes effective under the Securities Act. The Company shall have no
responsibility for information contained in the Registration Statements except
for information provided by the Company specifically for inclusion therein. The

subsidiaries to any governmental entity in connection with the Merger and the
other transactions contemplated by this Agreement.

Closing to supplement or amend promptly the Disclosure Schedules with respect to
any matter that would have been or would be required to be set forth or
described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on the Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Disclosure Schedule that constitutes or reflects a Material Adverse Effect on
APP may be made unless the Company consents to such amendment or supplement. For
purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 10.1 and 11.1 have been
fulfilled, the Disclosure Schedules hereto shall be deemed to be the Disclosure
Schedules as amended or supplemented pursuant to this Section 9.2. In the event
that the Company seeks to amend or supplement a Disclosure Schedule pursuant to
this Section 9.2 and APP does not consent to such amendment or supplement, or
APP seeks to amend or supplement a Disclosure Schedule pursuant to this Section
9.2, and the Company does not consent, this Agreement shall be deemed terminated
by mutual consent as set forth in Section 15.1(a) hereof.

knowingly, either before or after the Merger, take any action that would prevent
the Merger from qualifying as a tax-free exchange within the meaning of Sections
351 or 368 of the Code, as applicable.

         Section 9.4 Public Announcements. The parties hereto will consult with
each other before issuing any press release or making any public statement with

foregoing shall not apply to any disclosure by APP in any filing with the DOJ,
FTC or SEC.

         Section 9.5 Expenses. Each party to this Agreement shall be solely
responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by the Company and NewCo in connection with the Merger
shall be paid by the Company Stockholders in full immediately prior to the
Closing and such expenses shall be the sole responsibility of the Stockholders
following the Closing Date and not APP.

         Section 9.6 Patient Confidentiality. APP shall agree to keep all
records and information regarding the patients of the Company and NewCo
confidential in accordance with all applicable laws.

                  (i) executed Certificates of Merger necessary to effect the
Merger referred to in Section 2.1;

                  (j) the Merger Consideration in accordance with Article II and

of this Agreement.

                                  ARTICLE XIII

                              Post Closing Matters

         Section 13.1 Further Instruments of Transfer. Following the Closing, at
the request of APP or the Surviving Corporation and at APP's sole cost and
expense, the Stockholders and the Company shall deliver any further instruments
of transfer and take all reasonable action as may be necessary or appropriate to
carry out the purpose and intent of this Agreement. Following the Closing, at
the request of NewCo and at NewCo's sole cost and expense, APP or the Surviving

         Section 13.2 Merger Tax Covenant.

         (a) The parties intend that the Merger will qualify as a tax-free
transaction under Section 351 of the Code in which the Company will not
recognize gain or loss, and pursuant to which any gain recognized by a
Stockholder as a result of the Merger will not exceed the amount of any cash
received by a Stockholder in the Merger (a "Reorganization").

         (b) Both prior to and after the Effective Time, all books and records
shall be maintained, and all Tax Returns and schedules thereto shall be filed in
a manner consistent with the Merger being treated as a Reorganization. These
obligations are excused as to a party required to maintain the books or file a
Tax Return if such party has provided to the other parties a written opinion of
competent tax counsel to the effect that there is not substantial authority,
within the meaning of Section 6662(d)(2)(B)(i) of the Code, to report the Merger
as a Reorganization and such opinion either is furnished prior to the Effective
Time or is based on facts or events not known at the Effective Time. Each party
shall provide to each other party such tax information, reports, returns, or
schedules as may be reasonably required to assist such party in accounting for
and reporting the Merger as a Reorganization.

         (c) The parties agree that no Stockholder shall be liable for any taxes
incurred by the Company and for which APP has successor liability therefor which
arise solely as a result of the Merger or the consummation of the transactions
contemplated hereby; provided that the foregoing shall not limit


                                       37

or otherwise be deemed a waiver of any right of indemnification under Section
14.1 for a breach of any representation, warranty or covenant of the Company or
any Stockholder.

         Section 13.3 Current Public Information. APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

                                   ARTICLE XIV

                                    Remedies

         Section 14.1 Indemnification by the Company. Subject to the terms and
conditions of this Article XIV, the Company agrees to indemnify, defend and hold
APP and its respective directors, officers, stockholders, employees, agents,
attorneys, consultants and Affiliates harmless from and against all losses,
claims, obligations, demands, assessments, penalties, liabilities, costs,
damages, reasonable attorneys' fees and expenses (including, without limitation,
all costs of experts and all costs incidental to or in connection with any
appellate process) (collectively, "Damages") asserted against or incurred by
such individuals and/or entities arising out of or resulting from:

                  (a) a breach by the Company of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of the Company
contained in this Agreement or in any Schedule or certificate delivered
thereunder;

                  (b) any violation (or alleged violation) by the Company and/or
any of its past or present directors, officers, partners, stockholders,
employees (including, without limitation, any Physician Employee), agents,
attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons in
which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                  (c) any liability under the Securities Act, the Exchange Act
or any other federal or state "blue sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any (i) untrue statement
of material fact in any Registration Statement or any prospectus forming or part
thereof, or any amendment thereof or supplement thereto relating to the Company
(including any Company Subsidiary) or NewCo required to be stated therein or
(ii) failure to state information necessary to make the statements therein not
misleading, which untrue statement or failure to state information arises or
results solely from information provided in writing to APP or its counsel by the
Company or any Stockholder or their agents specifically for inclusion in any
such Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto.

         Section 14.2 Indemnification by APP. Subject to the terms and
conditions of this Article XIV, APP hereby agrees to indemnify, defend and hold
the Stockholders, the Company and NewCo and their respective directors,
officers, stockholders, employees, agents, attorneys, consultants and Affiliates
harmless from and against all Damages asserted against or incurred by such
individuals and/or entities arising out of or resulting from:

                  (a) a breach by APP of any representation or warranty (without
giving effect to any Material Adverse Effect qualifier contained as part of any
such representation or warranty) or covenant of APP contained in this Agreement
or in any schedule or certificate delivered hereunder; and

                  (b) any liability under the Securities Act, the Exchange Act
or any other federal or state "blue sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon


                                       38
<PAGE>   45
any untrue statements of material fact in any Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or required to be stated therein or failure to state information
necessary to make the statements therein not misleading (except for any
liability based upon any actual or alleged untrue statement of material fact or
an omission to state a material fact relating to NewCo, the Company or any
Stockholder which was derived from any information provided in writing by the
Company or a Company Subsidiary or any of their agents contained in the
representations and warranties set forth in this Agreement or any certificate,
exhibit, schedule or instrument required to be delivered under this Agreement.)

                  Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

         Section 14.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                  (a) Any party claiming indemnification under the Agreement (an
"Indemnified Party") shall promptly (and, in the event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party for whom indemnification is sought (the "Indemnifying
Party) of any third-party claim or claims asserted against the Indemnified Party
("Third Party Claim") that could give rise to a right of indemnification under
this Agreement and (ii) transmit to the Indemnifying Party a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of Damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement. The failure to promptly deliver a Claim Notice shall not relieve any
Indemnifying Party of its obligations to any Indemnified Party with respect to
the related Third Party Claim except to the extent that the resulting delay is
materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (x) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article XIV
with respect to such Third Party Claim and (y) whether the Indemnifying Party
desires, at the sole cost and expense of such Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

                  (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may


                                       39
<PAGE>   46
employ separate counsel at the expense of the Indemnifying Party, and upon
written notification thereof, the Indemnifying Party shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Party shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                  (c) If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to it that are different from or additional
to those available to the Indemnified Party, then the Indemnifying Party may
employ separate counsel and upon written notification thereof, the Indemnified
Party shall not have the right to assume the defense of such action on behalf of
the Indemnifying Party.

                  (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                  (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period


                                       40
<PAGE>   47
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

                  (f) The Indemnifying Party shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Party to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Party desired to accept such settlement.

                  (g) Notwithstanding any provision herein to the contrary, the
obligation of an Indemnifying Party to provide indemnification to an Indemnified
Party for breach of any representation or warranty as provided in Sections
14.1(a) or 14.2(a) hereof shall not take effect unless and until the Damages
asserted against or incurred in the aggregate and on a collective basis by the
Indemnified Parties pursuant to either Section 14.1 or 14.2 (as applicable) as a
result of such a breach or breaches exceeds $100,000.

         Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.

                                   ARTICLE XV

                                   Termination

         Section 15.1 Termination. This Agreement may be terminated and the
Merger and the Acquisitions may be abandoned:

agreement of all parties;

                  (b) at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and delivered
by the Company or any Stockholder pursuant to this Agreement is or becomes
untrue or breached in any material respect or if the Company or any Stockholder
fails to comply in any material respect with any material covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

                  (c) at any time prior to the Effective Date by the Company if
any representation or warranty of APP contained in this Agreement or in any
certificate or other document executed and delivered by APP pursuant to this
Agreement is or becomes untrue in any material respect of if APP fails to comply
in any material respect with any covenant or agreement contained herein, and any
such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;


                                       41
<PAGE>   48
                  (d) at any time prior to the Effective Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures, APP
deems termination to be advisable; or

                  (e) by APP or the Company if the Merger shall not have been
consummated by September 30, 1997.

         Section 15.2 Effect of Termination. Except as set forth in Section
16.3, in the event this Agreement is terminated pursuant to this Article XV,
this Agreement shall forthwith become void.

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

         Section 16.1 Non-Disclosure Covenant. The Company and NewCo recognize
and acknowledge that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP that is
valuable, special and a unique asset of such entity's business. APP acknowledges
that it had in the past, currently has, and in the future may possibly have,
access to certain Confidential Information of the Company and NewCo that is
valuable, special and a unique asset of each such business. The Company, NewCo
and APP, severally, agree that they will not disclose such Confidential
Information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
APP, NewCo and the Company and (b) to counsel and other advisers to APP, NewCo
and the Company provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 16.1, unless (i) such information
becomes available to or known by the public generally through no fault of the
Company, NewCo or APP, as the case may be, (ii) disclosure is required by law or
the order of any governmental authority under color of law, provided, that prior
to disclosing any information pursuant to this clause (ii) the Company, NewCo or
APP, as the case may be, shall, if possible, give prior written notice thereof
to the Company, NewCo or APP and provide the Company or APP with the opportunity
to contest such disclosure, (iii) the disclosing party reasonably believes that
such disclosure is required in connection with the defense of a lawsuit against
the disclosing party, or (iv) the disclosing party is the sole and exclusive
owner of such Confidential Information as a result of the Merger or otherwise.
In the event of a breach or threatened breach by the Company, on the one hand,
and APP, on the other hand, of the provisions of this Section, APP, NewCo and
the Company shall be entitled to an injunction restraining the other party, as
the case may be, from disclosing, in whole or in part, such Confidential
Information. Nothing herein shall be construed as prohibiting any of such
parties from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages.

         Section 16.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, NewCo and the Company agree that, in the event of
a breach by either of them of the foregoing covenant, the covenant may be
enforced against them by injunctions and restraining orders.

         Section 16.3 Survival. The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                  Miscellaneous

modified or supplemented only by an instrument in writing executed by all the
parties hereto. Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto. The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 17.2 Assignment. Neither this Agreement nor any right created
hereby or in any agreement entered into in connection with the transactions
contemplated hereby shall be assignable by any party hereto, except by APP to a
wholly owned subsidiary of APP; provided that any such assignment shall not

as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal

limitation, the rights and remedies under Article 14 hereof to indemnification
from APP against Damages incurred by the Stockholders resulting from a breach by
APP of any representation, warranty or covenant of APP contained herein. Except
as provided in the preceding sentence or as otherwise provided herein, neither

confer upon any person not a party hereto or thereto any rights or remedies
hereunder or thereunder.

contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,

to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 17.6 Survival of Representations, Warranties and Covenants. The
representations, warranties and covenants contained herein shall survive the

warranties by the Company, such Stockholder and APP. Notwithstanding any
provision in this Agreement to the contrary, the representations and warranties

Closing Date except that (a) the representations and warranties set forth in

the extent that any party to be indemnified pursuant to such provisions actually
incurs liability under the Securities Act, the Exchange Act or any other federal
or state securities law, the representations and warranties set forth therein
shall survive until the expiration of any applicable limitations period.

         Section 17.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING

material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party. To the knowledge of the
Company, there is no pending or threatened reassessment of any property covered
by the Lease Agreements. The Company or any Company Subsidiary will use
reasonable good faith efforts to obtain, prior to the Effective Time, the
consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver to
APP in writing such consents as are necessary to effect a valid and binding
transfer or assignment of the Company's or any Company Subsidiary's rights
thereunder. The Company has a good, clear, valid and enforceable leasehold
interest under each of the Lease Agreements. The Lease Agreements comply with
the exceptions to ownership interests and compensation arrangements set out in
42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952, and any similar applicable
state law safe harbor or other exemption provisions.

         Section 3.15      Real and Personal Property.

                    (a) Neither the Company nor any Company Subsidiary owns any
interest (other than the Lease Agreements) in real property.

                    (b) The Company and any Company Subsidiary (i) has good
title to all of its properties and assets (real, personal and mixed, tangible
and intangible) and any rights or interests therein


                                       11
<PAGE>   18

which it purports to own including, without limitation, all the property and
assets reflected in the Company Current Financial Statements; and (ii) owns such
rights, interests, assets and property free and clear of all Encumbrances, title
defects or objections (except for taxes not yet due and payable). The personal
property presently used in connection with the operation of the business of the
Company and the Company Subsidiaries constitutes the necessary personal property
assets to continue operation of the Company and any Company Subsidiary.

         Section 3.16 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, the Company does not have any
direct or indirect indebtedness for borrowed money, including indebtedness by
way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

         Section 3.17 Contracts and Commitments.

                  (a) The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health
maintenance organization, other managed care organization or other third-party
provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of
obligations of third parties requiring the Company to make, or setting forth
conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000 in
any fiscal year or $25,000 in the aggregate and that are not cancelable by
providing notice of sixty (60) days or less. All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is with
unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP of the assets and
properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP. In every instance where consent is necessary, the Company
shall, on or before the Closing Date, use reasonable good faith efforts to
obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts. Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. Notwithstanding the foregoing, the Company shall not transfer to APP
any contracts or agreements relating to the provision of professional medical
services or other such agreements and contracts that APP consents to in writing
to be transferred to NewCo in the Spin-off Transaction. No contract with a
health care provider or Payor has been materially amended or terminated within
the last twelve (12) months.

                  (b) The Company (i) has not received notice of any plan or
intention of any other party to exercise any right to cancel or terminate any
contract, agreement or instrument required to be disclosed pursuant to Section
3.17(a), and to the knowledge of the Company there are no fact(s) that would
justify the exercise of such a right; and (ii) does not currently contemplate,
or have reason to believe any other Person currently contemplates, any amendment
or change to any such contract, agreement or instrument.

         Section 3.18 Employee Matters. The Company is not currently a party to
any employment contract (except for oral employment agreements which are
terminable at will), consulting or collective bargaining contracts, deferred
compensation, pension plan (as defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974, as amended, and all rules and
regulations from time to time promulgated thereunder ("ERISA")), profit sharing,
bonus, stock option, stock purchase or other nonqualified benefit or
compensation commitments, benefit plans, arrangements or plans (whether written
or oral), including all welfare plans (as defined in Section 3(1) of ERISA) of
or pertaining to the Company and any of its present or former employees, or any
predecessors in interest. As of April 30, 1997, the Company employed a
collective total of [___] part-time and [____] full-time employees. The
Disclosure Schedules list each employee of, or consultant to, the Company who
received combined salary, benefits (other than those offered generally to all
other employees) and bonuses for 1996 in excess of $50,000 or who is expected to
receive combined salary, benefits (other than those offered generally to all
other employees) and bonuses in 1997 in excess of $50,000. The Company is not
delinquent in payment to any of its employees or Physician Employees for wages,
salaries, bonuses or other direct compensation for any services performed for it
to the date hereof or amounts required to be reimbursed to such employees. Upon
termination of employment of any employee or Physician Employee, no severance or
other payments will become due and the Company has no policy, past practice or

Employment Opportunity Commission or any federal, state or local agency or court
against the Company. There have been no governmental audits of the equal
employment opportunity practices of the Company and, to the knowledge of the
Company, no basis for any such audit exists which, if conducted would result in
a Material Adverse Effect on the Company;

                  (d) The Company is in material compliance with the Immigration
Reform and Control Act of 1986, as amended, and all applicable regulations
promulgated thereunder; and

                  (e) To the knowledge of the Company, there are no inquiries,
investigations or monitoring activities of any licensed, registered, or
certified professional personnel employed or retained by, credentialed or

Employee Benefit Plans can be terminated or amended at will by the Company
without any further liability or obligation on the part of such entity to make

Plan.

                  (b) Administration. Each Employee Benefit Plan has been

any Employee Benefit Plan is currently the subject of an audit, investigation,
enforcement action or other similar proceeding conducted by any state or federal

reasonably likely to result, directly or indirectly, (including through any
obligation of indemnification or contribution), in any taxes, penalties or other
liability to APP or any of its Affiliates.

                  (e) Claims and Litigation. No pending or, to the Company's

and, to the best knowledge of the Company and each Stockholder, has been
continually qualified under the applicable Section of the Code since the

Plan described in Section 501(c)(9) of the Code, the assets of each such plan
are at least equal in value to the present value of accrued benefits, based upon
the most recent actuarial valuation as of a date no more than ninety (90) days
prior to the date hereof. The Disclosure Schedules


                                       14

to determine the present value of accrued benefits under all Employee Benefit
Plans subject to actuarial assumptions.

of the Code.

                  (j) PBGC. No facts or circumstances are known to the Company
that would result in the imposition of liability against APP or any of its
Affiliates by the Pension Benefit Guaranty Corporation ("PBGC") as a result of
any act or omission by the Company or any member of a Controlled Group. No
reportable event (within the meaning of Section 4043 of ERISA) for which the

                  (l) Other Compensation Arrangements. Neither the Company nor,
to the Company's knowledge, any Stockholder or Physician Employee is a party to
any compensation or debt arrangement with any Person relating to the provision

                  (a) Neither the Company nor any Company Subsidiary has, within

would be reasonably likely to give rise to any Environmental Liabilities (as
defined in subsection (e) below) for the Company under any applicable
Environmental Law that had, or would reasonably be likely to have, a Material
Adverse Effect on the Company. Neither the Company nor any Company Subsidiary
has engaged in any activity or failed to undertake any activity which action or
failure to act has given, or would reasonably be likely to give, rise to any
Environmental Liabilities or enforcement action by any federal, state or local
regulatory agency or authority, or has resulted, or would reasonably be likely
to result, in any fine or penalty imposed pursuant to any Environmental Law.
Schedule 3.21(b) discloses any known presence of asbestos in or on the Company's

Company.

                  (d) There have been no environmental audits and other similar
reports which have been prepared by, for or, to the knowledge of the Company,
concerning the Company or any Company Subsidiary within the five (5) years

Subsidiary or any of its predecessors, true and complete copies of which have

                  (e) For the purposes of this Section 3.21, the following
terms have the following meanings:

                  "Environmental Laws" shall mean any federal, state or local
         laws, ordinances, codes, regulations, rules, policies and orders
         (including without limitation, Medical Waste Laws) that are intended to
         assure the protection of the environment, or that classify, regulate,

         Section 3.23 Insurance Policies. The Disclosure Schedules list and
briefly describe the Company's policies of insurance to which the Company or any
Company Subsidiary is a party or under which the Company or any Company
Subsidiary, officer or director thereof is or has been covered at any time

increase of deductibles, retainages or premiums is threatened. There are no
outstanding claims, settlements or premiums owed against any Insurance Policy,
and all required notices have been given and all known potential or actual
claims under any Insurance Policy have been presented in due and timely fashion.
Within the five (5) years preceding the Agreement, neither the Company nor any
Company Subsidiary has filed a written application for any professional
liability insurance coverage which has been denied by an insurance agency or
carrier. The Disclosure Schedules also set forth a list of all claims under any
Insurance Policy in excess of $10,000 per occurrence filed by the Company or any
Company Subsidiary during the immediately preceding three-year period. Each
Physician Employee has, at all times while a Physician Employee, maintained or

are customary for such a physician practicing the same type of medicine in the
same geographic area.

         Section 3.24      Accounts Receivable; Payors.

                  (a) The Disclosure Schedules set forth a list and aging of all
accounts receivable of the Company as of March 31, 1997, which list is complete,
true and accurate in all material respects. All such accounts receivable arose
in the ordinary course of business and have not been previously written off as
bad debts and, are, to the extent still uncollected, to the knowledge of the
Company collectible in the ordinary course of business, net of reserves for
doubtful and uncollectible accounts shown in the Company Financial Statements or
on the accounting records of the Company (which reserves are calculated
consistent with generally accepted accounting principles and past practice).

                  (b) The Disclosure Schedules set forth (i) a true, correct and
complete list of the names and addresses of each Payor of the Company as of such
date, which accounted for more than 5% of the revenues of the Company in the

for more than 5% of the revenues of the Company for the fiscal year to end
December 31, 1997, and (ii) a single line item listing for all private-pay
patients in the aggregate of the Company. The Company has satisfactory relations
with such Payors set forth in (i) above and none of such Payors has notified the
Company that it intends to discontinue its relationship with the Company or to
deny any payments due from, or any claims for payment submitted to any such
party.

         Section 3.25      Accounts Payable; Suppliers.

fiscal year ended December 31, 1996, or which is reasonably expected to account
for a dollar volume of purchases paid for by the Company in excess of $25,000
for the fiscal year to end December 31, 1997.

         Section 3.26 Inventory. All items of inventory on the Company Current
Balance Sheet contained in the Company Financial Statements consisted, and all
such items on hand on the date of this Agreement consist, and all such items on
hand at the Effective Time will consist, net of all applicable reserves with
respect thereto (calculated consistent with past practice), of items of a
quality and a quantity usable and saleable in the ordinary course of the
Company's business and conform to generally accepted standards in the industry
of which the Company is a part. The value of the inventories reflected on the
Company Current Balance Sheet contained in the Company Financial Statements are
net of adequate reserves for damaged, excess, and unusable items. Purchase
commitments of the Company for inventory


                                       17
<PAGE>   24

are not materially in excess of normal requirements, and none of such purchase
commitments are at prices in excess of prevailing market prices at the time of
such purchase commitment.

         Section 3.27      Licenses, Authorization and Provider Programs.

                  (a) The Company, and each Physician Employee and other
licensed employee or independent contractor of the Company (i) is the holder of
all valid licenses, approvals, orders, consents, permits, registrations,
qualifications and other rights and authorizations required by law, ordinance,
regulation or ruling of any governmental regulatory authority necessary to
operate its business or practice his or her specialty and (ii) is eligible to

Social Security Act (the "Medicare and Medicaid Programs") and any other
programs funded in whole or in part by federal, state or local entities for

("Governmental Programs"). The Company, the Stockholders, and each Physician
Employee has a current provider number for such Governmental Programs and with
such private non-governmental programs (including without limitation any private
insurance program) under which the Company is presently receiving payments
directly or indirectly from any Payor for patient care provided by such
Physician Employee, licensed employee or independent contractor (such
non-governmental programs herein referred to as "Private Programs"). A true,
correct and complete list of such licenses, permits and other authorizations
(including, but not limited to verification of Medicare and Medicaid provider
numbers and participating physician contracts under 1842(h) of the Social
Security Act), and provider agreements, is set forth in the Disclosure
Schedules, true, complete and correct copies of which have been provided to APP.
No violation, default, order or deficiency exists with respect to any of the
items listed in the Disclosure Schedules except for such violations, defaults,
orders or deficiencies which would not be reasonably likely to have a Material
Adverse Effect on the Company, and there is no action pending or to the
Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the

applicable laws, regulations and licensing requirements and has filed with the
proper authorities all necessary statements and reports, except where failure to

conducted in such a manner as to minimize the disruption to the Company's
ongoing business operations.

         Section 7.7       Intentionally omitted.

         Section 7.8 Stockholders' Consent. The Company shall use its best
efforts to obtain the unanimous approval of its Stockholders to the Merger. In
seeking the approval of its Stockholders, the Company shall provide each
Stockholder with the Form S-4 which shall include information as may be required
by applicable law or as APP shall deem appropriate. The Board of Directors of
the Company shall recommend the approval of the Merger by the Stockholders of
the Company. If the Stockholders' approval is not unanimous, the Company shall
give notice to the nonconsenting Stockholders of the action taken by the
consenting Stockholders as may be required by applicable law.

         Section 7.9 Obligations of Company and Stockholders. Subject to Section
7.8 hereof, the Company will take all action reasonably necessary to cause the
Company to perform its obligations under this Agreement and all related
agreements and to consummate the Merger and other transactions contemplated

such agreements; provided, however, that this covenant shall not require the
Company to make any expenditures that are not expressly set forth in this
Agreement or otherwise contemplated herein.

        Section 7.10 Funding of Accrued Employee Benefits. The Company hereby
covenants and agrees that it will take whatever steps are necessary to pay for

<PAGE>   36

where applicable, or vested accrued benefits for which the Company or any entity
might have any liability whatsoever arising from any tax-qualified plan as
required under applicable law. The Company acknowledges that the purpose and
intent of this covenant is to assure that APP shall have no liability whatsoever
at any time after the Closing Date with respect to any such tax-qualified plan,
unless such plan is merged with a plan sponsored by APP.

         Section 7.11 Accounting and Tax Matters. The Company will not change in
any material respect the accounting methods or practices followed by the Company

accounting method except in the ordinary course of business consistent with past
practice, change any tax accounting method, enter into any closing agreement,
settle any tax claim or assessment or consent to any tax claim or assessment or
any waiver of the statute of limitations for any such claim or assessment. The

taxes of the Company required to be filed by it, and pay all taxes required to
be paid by it, on or before the Closing Date.

         Section 7.12 Spin-Off Transaction. The Company shall form, organize and
incorporate NewCo in the state of New York, and the articles or certificate of
incorporation and bylaws of NewCo shall be in form and substance reasonably
satisfactory to APP. Except for consummating the Spin-Off Transaction, NewCo

the Company shall take all actions and execute all documents, agreements or
instruments necessary pursuant to and in compliance with applicable law to
effect the Spin-Off Transaction, including without limitation, the following:
Prior to the Closing, the Company shall transfer to NewCo good, valid and
marketable title to all of the Company's right, title and interest in and to the
Employee Benefit Plans, all contracts and agreements and other assets listed on
the Disclosure Schedules (to be delivered by the Company prior to Closing, which
schedule will be subject to the approval of APP, which approval shall not be
unreasonably withheld) which by law either cannot be acquired or cannot be used
by APP because they relate to the practice of medicine or radiology, and shall
contribute to NewCo such other consideration and assets of the Company as may be
required under applicable law, in exchange for the issuance by NewCo of shares
of NewCo Common Stock, such shares being all of the issued and outstanding
shares of NewCo Common Stock. The Company shall then distribute the shares of
NewCo Common Stock to the Stockholders in proportion to their respective
ownership interest in the Company.

         Section 7.13 "F" Reorganization. The Company shall convert its
corporate status from that of a professional medical corporation to that of a

The Company shall prepare and execute all documents necessary to effectuate the
"F" Reorganization prior to the Closing. At or prior to the Closing, the Company
shall cause an amendment to this Agreement to be executed which will reflect the
changes which result from the "F" Reorganization.

and, at the Company's sole expense, make copies of all documents, records and
information with respect to the affairs of APP as the Company and their
representatives may reasonably request, all for the sole purpose of permitting
the Company to become familiar with the business and assets and liabilities of
APP. No investigation by the Company or the Stockholders shall diminish or
otherwise affect any of the representations, warranties, covenants or agreements
of APP under this Agreement.

         Section 8.4 Notification of Certain Matters. APP shall promptly inform
the Company in writing of (a) any notice of, or other communication relating to,
a default or event that, with notice or lapse of time or both, would become a
default, received by APP subsequent to the date of this Agreement and prior to
the Effective Time under any contract, agreement or investment material to APP's
condition (financial or otherwise), operations, assets, liabilities or business
and to which it is subject; (b) any material adverse change in APP's condition
(financial or otherwise), operations, assets, liabilities or business or (c)
defaults or disputes regarding Other Agreements.

         Section 8.5 Qualified Retirement Plans. APP shall use its best efforts
to establish a qualified plan and trust for NewCo, within the meaning of Section
401(a) and 501(a), respectively, of the Code ("New Qualified Plan") that will
provide benefits comparable (as determined under Section 401(a)(4) of the Code)
to the benefits provided under the qualified plans referenced in the Disclosure
Schedules, if any, sponsored by the Company as of March 31, 1997. APP will file
for a favorable determination letter from the IRS on the New Qualified Plan and
request a favorable determination from the IRS that NewCo is not a member of an
affiliated service group (as defined in Section 414(m) of the Code) or a
recipient organization of leased employee services (as defined in Section 414(n)
of the Code). Any benefits provided under the New Qualified Plan shall be
conditioned on a favorable determination letter from the IRS. Costs associated
with the establishment and design of the New Qualified Plan shall be paid by
APP. The NewCo shall be responsible for funding any contributions to, or any
ongoing administrative costs of, the New Qualified Plan.

                                   ARTICLE IX

         APP and the Company agree as follows:

         Section 9.1  Filings; Other Action.

         (a) The Company shall cooperate with APP to promptly prepare and file
with the SEC the Registration Statements on Form S-1 and Form S-4 (or other
appropriate Forms) to be filed by APP in connection with its Initial Public
Offering and offering of the shares of APP Common Stock to the Target Interest
Holders pursuant to the transactions contemplated by this Agreement and the
Other Agreements (including the prospectus constituting parts thereof, the
"Registration Statements"). APP shall obtain all necessary state securities law
or "Blue Sky" permits and approvals required to carry out the transactions
contemplated by this Agreement. The Company shall cooperate with APP in the
preparation of the Registration Statements and shall furnish all information
concerning the Company and NewCo as may be reasonably requested in connection
with any such action in a timely manner.

         (b) The Company and APP and each separately represent and warrant that
(i) in the case of the Company, none of the written information or documents
supplied or to be supplied by it specifically

                                       31
<PAGE>   38

for inclusion in the Registration Statements, by exhibit or otherwise and (ii)
in the case of APP, will, at the time the Registration Statements and each
amendment and supplement thereto, if any, becomes effective under the Securities
Act, none of them contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The Company shall be entitled to review the Registration
Statements and each of the amendments thereto, if any, prior to the time each
becomes effective under the Securities Act. The Company shall have no
responsibility for information contained in the Registration Statements except
for information provided by the Company specifically for inclusion therein. The
Company's review of the Registration Statements shall not diminish or otherwise
affect the representations, covenants and warranties of APP contained in this
Agreement.

         (c) The Company shall, upon request, furnish APP with all information
concerning itself, its subsidiaries, directors, officers, partners, Stockholders
and NewCo, and such other matters as may be reasonably requested by APP in
connection with the preparation of the Registration Statements and each of the
amendments or supplements thereto, or any other statement, filing, notice or
application made by or on behalf of each such party or any of its subsidiaries
to any governmental entity in connection with the Merger and the other
transactions contemplated by this Agreement.

         Section 9.2 Amendments of Schedules. Each party hereto agrees that,
with respect to the representations and warranties of such party contained in
this Agreement, such party shall have the continuing obligation until the
Closing to supplement or amend promptly the Disclosure Schedules with respect to
any matter that would have been or would be required to be set forth or
described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on the Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Disclosure Schedule that constitutes or reflects a Material Adverse Effect on
APP may be made unless the Company consents to such amendment or supplement. For
purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 10.1 and 11.1 have been
fulfilled, the Disclosure Schedules hereto shall be deemed to be the Disclosure
Schedules as amended or supplemented pursuant to this Section 9.2. In the event

obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                  (c) any liability under the Securities Act, the Exchange Act

of material fact in any Registration Statement or any prospectus forming or part
thereof, or any amendment thereof or supplement thereto relating to the Company
(including any Company Subsidiary) or NewCo required to be stated therein or
(ii) failure to state information necessary to make the statements therein not
misleading, which untrue statement or failure to state information arises or

amendment thereof or supplement thereto.

<PAGE>   45

any untrue statements of material fact in any Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or required to be stated therein or failure to state information
necessary to make the statements therein not misleading (except for any
liability based upon any actual or alleged untrue statement of material fact or
an omission to state a material fact relating to NewCo, the Company or any
Stockholder which was derived from any information provided in writing by the
Company or a Company Subsidiary or any of their agents contained in the
representations and warranties set forth in this Agreement or any certificate,
exhibit, schedule or instrument required to be delivered under this Agreement.)

                  Notwithstanding anything contained in either Sections 14.1 or

any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

         Section 14.3 Conditions of Indemnification.  All claims for 
indemnification under this Agreement shall be asserted and resolved as follows:

                  (a) Any party claiming indemnification under the Agreement (an
"Indemnified Party") shall promptly (and, in the event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party for whom indemnification is sought (the "Indemnifying
Party) of any third-party claim or claims asserted against the Indemnified Party
("Third Party Claim") that could give rise to a right of indemnification under
this Agreement and (ii) transmit to the Indemnifying Party a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of Damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement. The failure to promptly deliver a Claim Notice shall not relieve any
Indemnifying Party of its obligations to any Indemnified Party with respect to
the related Third Party Claim except to the extent that the resulting delay is
materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (x) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article XIV
with respect to such Third Party Claim and (y) whether the Indemnifying Party
desires, at the sole cost and expense of such Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

                  (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may


                                       39
<PAGE>   46

employ separate counsel at the expense of the Indemnifying Party, and upon
written notification thereof, the Indemnifying Party shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Party shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                  (c) If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to it that are different from or additional
to those available to the Indemnified Party, then the Indemnifying Party may
employ separate counsel and upon written notification thereof, the Indemnified
Party shall not have the right to assume the defense of such action on behalf of
the Indemnifying Party.

                  (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                  (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period


                                       40
<PAGE>   47

for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

                  (f) The Indemnifying Party shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Party to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Party desired to accept such settlement.

                  (g) Notwithstanding any provision herein to the contrary, the
obligation of an Indemnifying Party to provide indemnification to an Indemnified
Party for breach of any representation or warranty as provided in Sections
14.1(a) or 14.2(a) hereof shall not take effect unless and until the Damages
asserted against or incurred in the aggregate and on a collective basis by the
Indemnified Parties pursuant to either Section 14.1 or 14.2 (as applicable) as a
result of such a breach or breaches exceeds $100,000.

         Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.

                                   ARTICLE XV

                                   Termination

        Section 15.1 Termination. This Agreement may be terminated and the
Merger and the Acquisitions may be abandoned:

                  (a) at any time prior to the Effective Date by mutual
agreement of all parties;

                  (b) at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and delivered
by the Company or any Stockholder pursuant to this Agreement is or becomes
untrue or breached in any material respect or if the Company or any Stockholder
fails to comply in any material respect with any material covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

                  (c) at any time prior to the Effective Date by the Company if
any representation or warranty of APP contained in this Agreement or in any
certificate or other document executed and delivered by APP pursuant to this
Agreement is or becomes untrue in any material respect of if APP fails to comply
in any material respect with any covenant or agreement contained herein, and any
such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;


                                       41
<PAGE>   48

                  (d) at any time prior to the Effective Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures, APP
deems termination to be advisable; or

                  (e) by APP or the Company if the Merger shall not have been
consummated by September 30, 1997.

         Section 15.2 Effect of Termination. Except as set forth in Section
16.3, in the event this Agreement is terminated pursuant to this Article XV,
this Agreement shall forthwith become void.

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

         Section 16.1 Non-Disclosure Covenant. The Company and NewCo recognize
and acknowledge that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP that is
valuable, special and a unique asset of such entity's business. APP acknowledges
that it had in the past, currently has, and in the future may possibly have,
access to certain Confidential Information of the Company and NewCo that is
valuable, special and a unique asset of each such business. The Company, NewCo
and APP, severally, agree that they will not disclose such Confidential
Information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
APP, NewCo and the Company and (b) to counsel and other advisers to APP, NewCo
and the Company provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 16.1, unless (i) such information
becomes available to or known by the public generally through no fault of the
Company, NewCo or APP, as the case may be, (ii) disclosure is required by law or
the order of any governmental authority under color of law, provided, that prior
to disclosing any information pursuant to this clause (ii) the Company, NewCo or
APP, as the case may be, shall, if possible, give prior written notice thereof
to the Company, NewCo or APP and provide the Company or APP with the opportunity
to contest such disclosure, (iii) the disclosing party reasonably believes that
such disclosure is required in connection with the defense of a lawsuit against
the disclosing party, or (iv) the disclosing party is the sole and exclusive
owner of such Confidential Information as a result of the Merger or otherwise.
In the event of a breach or threatened breach by the Company, on the one hand,
and APP, on the other hand, of the provisions of this Section, APP, NewCo and
the Company shall be entitled to an injunction restraining the other party, as
the case may be, from disclosing, in whole or in part, such Confidential
Information. Nothing herein shall be construed as prohibiting any of such
parties from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages.

         Section 16.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, NewCo and the Company agree that, in the event of
a breach by either of them of the foregoing covenant, the covenant may be
enforced against them by injunctions and restraining orders.

        Section 16.3 Survival. The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                  Miscellaneous

         Section 17.1 Amendment; Waivers. This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto. Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto. The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 17.2 Assignment. Neither this Agreement nor any right created
hereby or in any agreement entered into in connection with the transactions
contemplated hereby shall be assignable by any party hereto, except by APP to a
wholly owned subsidiary of APP; provided that any such assignment shall not
relieve APP of its obligations hereunder.

         Section 17.3 Parties in Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. APP acknowledges
and agrees that the rights and remedies of the Company under this Agreement will

rights and remedies of the Company under this Agreement, including, without
limitation, the rights and remedies under Article 14 hereof to indemnification
from APP against Damages incurred by the Stockholders resulting from a breach by
APP of any representation, warranty or covenant of APP contained herein. Except
as provided in the preceding sentence or as otherwise provided herein, neither
this Agreement nor any other agreement contemplated hereby shall be deemed to

hereunder or thereunder.

         Section 17.4 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 17.6 Survival of Representations, Warranties and Covenants. The
representations, warranties and covenants contained herein shall survive the
Closing and all statements contained in any certificate, exhibit or other
instrument delivered by or on behalf of the Company, any Stockholder or APP
pursuant to this Agreement shall be deemed to have been representations and
warranties by the Company, such Stockholder and APP. Notwithstanding any
provision in this Agreement to the contrary, the representations and warranties
contained herein shall survive the Closing until the second anniversary of the
Closing Date except that (a) the representations and warranties set forth in
Section 3.21 with respect to environmental matters shall survive for a period of
ten (10) years, (b) the representations and warranties set forth in Section 3.30
with respect to tax matters shall survive until such time as the limitations
period has run for all tax periods ended prior to the Closing Date, (c) the
representations and warranties contained in Section 3.27 and Section 3.33 with
respect to healthcare matters shall survive for a period of six (6) years and
(d) solely for purposes of Section 14.1(c) and Section 14.2(c), and solely to
the extent that any party to be indemnified pursuant to such provisions actually
incurs liability under the Securities Act, the Exchange Act or any other federal
or state securities law, the representations and warranties set forth therein
shall survive until the expiration of any applicable limitations period.

         Section 17.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

        Section 17.8 Captions. The captions in this Agreement are for

                 (a)      As a result of the Merger and without any action on
the part of the holder thereof, all shares of Company Common Stock issued and
outstanding at the Effective Time (excluding shares held by APP pursuant to
Section 2.8(d) hereof) shall cease to be outstanding and shall be cancelled and

certificates representing any such shares of Company Common Stock shall
thereafter cease to have any rights with respect to such shares of Company
Common Stock, except the right to receive, without interest, (i) cash and (ii)
validly issued, fully paid and nonassessable shares of APP Common Stock, all as

                 (b)      Each share of Company Common Stock held in the
Company's treasury, if any, at the Effective Time, by virtue of the Merger,
shall be cancelled and retired without payment of any consideration therefor
and shall cease to exist.

                 (c)      Each Company Right outstanding at the Effective Time
shall be terminated and cancelled, without payment of any consideration

shares of the Company's Common Stock, shall upon surrender of each certificate
or certificates (or completion of appropriate affidavit of lost certificate and
indemnity) receive such allocation of Merger Consideration as determined in
accordance with the provisions of Exhibit B attached hereto; and (ii) until
each certificate or certificates representing Company Common Stock have been
surrendered by the Stockholders, the certificates for Company Common Stock
shall, for all purposes, represent solely the right to receive Merger
Consideration as determined in accordance with the provisions of Exhibit B
attached hereto and Section 2.10 hereof, if applicable.  At the Effective Time,
each share of Company Common Stock converted into Merger Consideration shall by
virtue of the Merger and without any action on the part of the holders thereof,
cease to be outstanding, be cancelled and returned and all shares of APP Common
Stock issuable to the Stockholders in the Merger as part of the Merger

stamps, acquired at the Stockholder's expense, affixed and cancelled.  Each
Stockholder agrees

Consideration pursuant to Exhibit B and Section 2.10 hereof, if applicable.

         Section 2.10     Fractional Shares.  Notwithstanding any other
provision herein, no fractional shares of APP Common Stock will be issued and
any Stockholder otherwise entitled to receive a fractional share of APP Common
Stock as part of the Merger Consideration hereunder shall receive a cash
payment in lieu thereof reflecting such Stockholder's proportionate interest in
a share of APP Common Stock multiplied by the Initial Public Offering Price.

Company is a corporation duly organized, validly existing and in good standing
under the laws of its state of incorporation, with all requisite corporate
power and authority to own, operate and lease its assets and properties and to
carry on its business as currently conducted.  The Company and each Company
Subsidiary is in good standing in each jurisdiction where the character of the
property owned or leased by it or the nature of its activities makes such
qualification necessary, except where such failure to be so qualified or in
good standing would not have a Material Adverse Effect on the Company.  Copies
of the articles or certificates of incorporation and all amendments thereto of
the Company and each Company Subsidiary and the bylaws of the Company and each
Company Subsidiary, as amended, and copies of the corporate minutes of the
Company, all of which have been or will be made available to APP for review,
are true and complete as in effect on the date of this Agreement, and in the
case of the corporate minutes, accurately reflect all material proceedings of
the Stockholders and directors of the Company (and all committees thereof).
The stock record books of the Company, which have been or will be made
available to APP for review, contain true, complete and accurate records of the
stock ownership of record of the Company and the transfer record of the shares
of its capital stock.

         Section 3.2      Authorization and Validity.  The Company has all
requisite corporate power to enter into this Agreement and all other agreements

Board of Directors.  Subject to the approval of this Agreement and the Merger
by the Stockholders, this Agreement has been duly executed by the Company, and
this Agreement and all other agreements and obligations entered into and
undertaken in connection with the transactions contemplated hereby to which the
Company is a party constitute, or upon execution will constitute, valid and
binding agreements of the Company, enforceable against it in accordance with
their respective terms, except as enforceability may be limited by bankruptcy
or other laws affecting the enforcement of creditors' rights generally, or by
general equity principles, or by public policy.

         Section 3.3      Governmental Authorization.  Other than complying
with the provisions of the applicable state corporate laws regarding the
approval of the Merger and the filing of the Certificates of Merger (as
contemplated by Section 2.3) and any other required documents related to the

any Hart-Scott-Rodino filing to be made by APP, if any), the execution,
delivery and performance by the Company of this Agreement and the agreements
provided for herein, and the consummation of the transactions contemplated
hereby and thereby by the Company require no action by or in respect of, or
filing with, any governmental body, agency, official or authority.

         Section 3.4      Capitalization.  The authorized capital stock of the
Company consists of 200 shares of the Company Common Stock, of which 130 shares
are issued and outstanding.  The Stockholders collectively are and will be
immediately prior to the Effective Time the record and beneficial owners of all
the issued and outstanding Company Common Stock, free and clear of all
Encumbrances, in the respective amounts set forth in the Disclosure Schedules.
Each outstanding share of Company Common Stock has been legally and validly
issued and is fully paid and nonassessable, and was issued pursuant to a valid
exemption from registration under (i) the Securities Act of 1933, as amended,
and (ii) all applicable state securities laws.  No shares of Company Common
Stock are owned by the Company in treasury.  No shares of Company Common Stock
have been issued or disposed of in violation of any preemptive rights, rights
of first refusal or similar rights of any of the Stockholders.  Other than
Company Common Stock, the Company has no securities, bonds, debentures, notes
or other obligations the holders of which have the right to vote (or are
convertible into or exercisable for securities having the right to vote) with
the Stockholders on any matter.

         Section 3.5      Transactions in Capital Stock.  There exist no
Company Rights.  The Company has no obligation (contingent or otherwise) to
purchase, redeem or otherwise acquire any of its equity securities or any
interests therein or to pay any dividend or make any distribution in respect
thereof.  Neither the equity structure of the Company nor the relative

this Agreement.

any of its Affiliates other than in the ordinary course of business within the

         Section 3.7      Subsidiaries and Investments.  The Company does not
own, directly or indirectly, any capital stock or other equity, ownership or
proprietary interest in any corporation, partnership, association, trust, joint
venture or other entity (each a "Company Subsidiary").

         Section 3.8      Absence of Conflicting Agreements or Required
Consents.  Subject to approval of this Agreement and the Merger by the
Stockholders of the Company, the execution, delivery and performance by the
Company of this Agreement and any other documents contemplated hereby (with or
without the giving of notice, the lapse of time, or both): (i) do not require
the consent of any governmental or regulatory body or authority or any other
third party except for such consents, for which the failure to obtain would not
result in a Material Adverse Effect on the Company; (ii) will not conflict with
or result in a violation of any provision of the Company's articles or
certificate of incorporation or bylaws, (iii) will not conflict with, result in
a violation of, or constitute a default under any law, rule, ordinance,

required by the terms of any agreement, instrument, license or permit, to which
the Company is a party or by which the Company or any of its properties are
subject or bound except for such conflict, termination, breach or default, the
occurrence of which would not result in a Material Adverse Effect on the
Company; and (v) except as contemplated by this Agreement, will not create any
Encumbrance or restriction upon the Company Common Stock or any of the assets
or properties of the Company.

         Section 3.9      Intentionally omitted.

         Section 3.12     Litigation and Claims.  There are no claims,
lawsuits, actions, arbitrations, administrative or other proceedings,
governmental investigations or inquiries pending or, to the knowledge of the
Company, threatened against, or affecting the Company, any Company Subsidiary,
any Stockholder, the Physician Employees or any other licensed professional or
other individual affiliated with the Company affecting or that would reasonably
be likely to affect the Company Common Stock or the operations, business
condition, (financial or otherwise), or results of operations of the Company
which (i) if successful, may, individually or in the aggregate, have a Material
Adverse Effect on the Company or (ii) could adversely affect the ability of the
Company or any Company Subsidiary to effect the transactions contemplated
hereby, and to the knowledge of the Company there is no basis for any such
action or any state of facts or occurrence of any event which would reasonably
be likely to give rise to the foregoing.  There are no unsatisfied judgments
against the Company or any Company Subsidiary or any licensed professional or
other individual affiliated with the Company or any Company Subsidiary relating
to services provided on behalf of the Company or any Company Subsidiary or any
consent decrees to which any of the foregoing is subject.  Each of the matters,
if any, set forth in this Section 3.12 is fully covered by policies of
insurance of the Company or any Company Subsidiary as in effect on the date
hereof.

         Section 3.13     No Violation of Law.  Neither the Company nor any
Company Subsidiary has been, nor shall be as of the Effective Time (by virtue
of any action, omission to act, contract to which it is a party or any
occurrence or state of facts whatsoever), in violation of any applicable local,
state or federal law, ordinance, regulation, order, injunction or decree, or
any other requirement of any governmental body, agency, authority or court
binding on it, or relating to its properties, assets or business or its
advertising, sales or pricing practices, except for violations which,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on the Company.

         Section 3.14     Lease Agreements.  The Disclosure Schedules contain a
true, accurate and complete list of all the lease agreements and license
agreements to which the Company or any Company Subsidiary is a party and
pursuant to which the Company or any Company Subsidiary leases (whether as
lessor or lessee) or licenses (whether as licensor or licensee) any real or
personal property related to the operation of its business and which requires
payments in excess of $12,000 per year (the "Lease Agreements").  The Company
has delivered to APP true and complete copies of all of the Lease Agreements.
Each Lease Agreement is valid, effective and in full force in accordance with
its terms, and there is not under any such lease (i) any existing or claimed
material default by the Company or any Company Subsidiary (as applicable) or
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by the Company or any Company Subsidiary
(as applicable) and, individually or in the aggregate, may reasonably result in
a Material Adverse Effect on the Company, or, (ii) to the knowledge of the
Company, any existing material default by any other party under any of the
Lease Agreements or any event of material default or event which with notice or
lapse of time, or both, would constitute a material default by any such party.
To the knowledge of the Company, there is no pending or threatened reassessment
of any property covered by the Lease Agreements.  The Company or any Company
Subsidiary will use reasonable good faith efforts to obtain, prior to the
Effective Time, the consent of each landlord or lessor whose consent is
required to the assignment of the Lease Agreements and will use reasonable good
faith efforts to deliver to APP in writing such consents as are necessary to
effect a valid and binding transfer or assignment of the Company's or any
Company Subsidiary's rights thereunder.  The Company has a good, clear, valid
and enforceable leasehold interest under each of the Lease Agreements.  The
Lease Agreements comply with the exceptions to ownership interests and
compensation arrangements set out in 42 U.S.C. Section  1395nn, 42 C.F.R.
Section  1001.952, and any similar applicable state law safe harbor or other
exemption provisions.

         Section 3.15     Real and Personal Property.

                 (a)      Neither the Company nor any Company Subsidiary owns
any interest (other than the Lease Agreements) in real property.

                 (b)      The Company and any Company Subsidiary (i) has good
title to all of its properties and assets (real, personal and mixed, tangible
and intangible) and any rights or interests therein





                                       11
<PAGE>   18
which it purports to own including, without limitation, all the property and
assets reflected in the Company Current Financial Statements; and (ii) owns
such rights, interests, assets and property free and clear of all Encumbrances,
title defects or objections (except for taxes not yet due and payable).  The
personal property presently used in connection with the operation of the
business of the Company and the Company Subsidiaries constitutes the necessary
personal property assets to continue operation of the Company and any Company
Subsidiary.

         Section 3.16     Indebtedness for Borrowed Money.  Except for trade
payables incurred in the ordinary course of business, the Company does not have
any direct or indirect indebtedness for borrowed money, including indebtedness
by way of lease-purchase arrangements or guarantees, and is not obligated in
any manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

         Section 3.17     Contracts and Commitments.

                 (a)      The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies,
of each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate
(other than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health
maintenance organization, other managed care organization or other third-party
provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of
obligations of third parties requiring the Company to make, or setting forth
conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000
in any fiscal year or $25,000 in the aggregate and that are not cancelable by
providing notice of sixty (60) days or less.  All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is
with unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP of the assets and
properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP.  In every instance where consent is necessary, the
Company shall, on or before the Closing Date, use reasonable good faith efforts
to obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts.  Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement.  Notwithstanding the foregoing, the Company shall not transfer to
APP any contracts or agreements relating to the provision of professional
medical services or other such agreements and contracts that APP consents to in
writing to be transferred to NewCo in the Spin-off Transaction.  No contract
with a health care provider or Payor has been materially amended or terminated
within the last twelve (12) months.

                 (b)      The Company (i) has not received notice of any plan
or intention of any other party to exercise any right to cancel or terminate
any contract, agreement or instrument required to be disclosed pursuant to
Section 3.17(a), and to the knowledge of the Company there are no fact(s) that
would justify the exercise of such a right; and (ii) does not currently
contemplate, or have reason to believe any other Person currently contemplates,
any amendment or change to any such contract, agreement or instrument.

         Section 3.18     Employee Matters.  The Company is not currently a
party to any employment contract (except for oral employment agreements which
are terminable at will), consulting or collective bargaining contracts,

compensation commitments, benefit plans, arrangements or plans (whether written

predecessors in interest.  As of April 30, 1997, the Company employed a
collective total of [___] part-time and [____] full-time employees.  The

other employees) and bonuses in 1997 in excess of $50,000.  The Company is not

                 (a)      Identification.  The Disclosure Schedules contain a
complete and accurate list of all employee benefit plans (within the meaning of
Section 3(3) of ERISA) sponsored by the Company or to which the Company
contributes on behalf of its employees and all employee benefit plans
previously sponsored or contributed to on behalf of its employees within the
three years preceding the date hereof (the "Employee Benefit Plans").  The

amended to the date hereof), determination letters, pending determination
letter applications, trust instruments, insurance contracts or policies related
to an Employee Benefit Plan, administrative services contracts, annual reports,
actuarial valuations, summary plan descriptions, summaries of material
modifications, administrative forms and other documents that constitute a part
of or are incident to the administration of the Employee Benefit Plans.  In
addition, the Company has provided or made available to APP a written
description of all existing practices engaged in by the Company that constitute
Employee Benefit Plans.  Subject to the requirements of ERISA, each of the
Employee Benefit Plans can be terminated or amended at will by the Company
without any further liability or obligation on the part of such entity to make
further contributions or payments in connection therewith following such
termination.  No unwritten amendment exists with respect to any Employee
Benefit Plan.

                 (b)      Administration.  Each Employee Benefit Plan has been
administered and maintained in compliance with all applicable laws, rules and
regulations, except where the failure to be in compliance would not,
individually or in the aggregate, result in a Material Adverse Effect.

                 (c)      Examinations.  The Company has not received any
notice that any Employee Benefit Plan is currently the subject of an audit,
investigation, enforcement action or other similar proceeding conducted by any
state or federal agency or authority.

                 (d)      Prohibited Transactions.  No prohibited transactions
(within the meaning of Section 4975 of the Code or Section 406 of ERISA) have
occurred with respect to any Employee Benefit Plan.  There has been no breach
of any duty under ERISA or applicable law (including, without limitation, any
health care contractor requirements or any other tax law requirements, or
conditions to favorable tax treatment, applicable to such plan), which would be
reasonably likely to result, directly or indirectly, (including through any
obligation of indemnification or contribution), in any taxes, penalties or
other liability to APP or any of its Affiliates.

                 (e)      Claims and Litigation.  No pending or, to the
Company's knowledge, threatened, claims, suits or other proceedings exist with
respect to any Employee Benefit Plan other than normal benefit claims filed by
participants or beneficiaries.

                 (f)      Qualification.  The Company has received a favorable
determination letter or ruling from the IRS for each of the Employee Benefit
Plans intended to be qualified within the meaning of Section 401(a) or
501(c)(9) of the Code and/or tax-exempt within the meaning of Section 501(a) of
the Code and, to the best knowledge of the Company and each Stockholder, has
been continually qualified under the applicable Section of the Code since the
effective date of such Employee Benefit Plan.  No proceedings exist or, to the
Company's knowledge, have been threatened that could result in the revocation
of any such favorable determination letter or ruling.

                 (g)      Funding Status.  No accumulated funding deficiency
(within the meaning of Section 412 of the Code), whether waived or unwaived,
exists with respect to any Employee Benefit Plan or any plan sponsored by any
member of a controlled group (within the meaning of Section 412(n)(6)(B) of the
Code) in which the Company is a member (a "Controlled Group").  With respect to
each Employee Benefit Plan subject to Title IV of ERISA, the assets of each
such plan are at least equal in value to the present value of accrued benefits
determined on an ongoing basis as of the date hereof.  With respect to each
Employee Benefit Plan described in Section 501(c)(9) of the Code, the assets of
each such plan are at least equal in value to the present value of accrued
benefits, based upon the most recent actuarial valuation as of a date no more
than ninety (90) days prior to the date hereof.  The Disclosure Schedules





                                       14

contain a complete and accurate statement of all actuarial assumptions applied
to determine the present value of accrued benefits under all Employee Benefit
Plans subject to actuarial assumptions.

                 (h)      Excise Taxes.  Neither the Company nor any member of
a Controlled Group has any liability to pay excise taxes with respect to any
Employee Benefit Plan under applicable provisions of the Code or ERISA.

                 (i)      Multiemployer Plans.  Neither the Company nor any
member of a Controlled Group is or ever has been obligated to contribute to a
multiemployer plan within the meaning of Section 3(37) of ERISA or any other
Employee Benefit Plan which has been subject to Title IV of ERISA or Section
412 of the Code.

                 (j)      PBGC.  No facts or circumstances are known to the
Company that would result in the imposition of liability against APP or any of
its Affiliates by the Pension Benefit Guaranty Corporation ("PBGC") as a result
of any act or omission by the Company or any member of a Controlled Group.  No
reportable event (within the meaning of Section 4043 of ERISA) for which the
notice requirement has not been waived has occurred with respect to any
Employee Benefit Plan subject to the requirements of Title IV of ERISA.

                 (k)      Retirees.  The Company has no obligation or
commitment to provide medical, dental or life insurance benefits to or on
behalf of any of its employees who may retire or any of its former employees
who have retired except as may be required pursuant to the continuation of
coverage provisions of Section 4980B of the Code and the applicable provisions
of ERISA.

                 (l)      Other Compensation Arrangements.  Neither the Company
nor, to the Company's knowledge, any Stockholder or Physician Employee is a
party to any compensation or debt arrangement with any Person relating to the
provision of health care related services other than arrangements with the
Company.

         Section 3.21     Environmental Matters.

                 (a)      Neither the Company nor any Company Subsidiary has,

any governmental entity, with respect to any (i) alleged violation by the
Company of any Environmental Law (as defined in subsection (e) below) (ii)
alleged failure by the Company to have any environmental permit, certificate,

                 (b)      Neither the Company nor any Company Subsidiary has
used, transported, disposed of or arranged for the disposal of (as those terms
are defined in and construed under the Comprehensive Environmental Response,
Compensation and Liability Act) any Hazardous Substance (as defined herein)
that would be reasonably likely to give rise to any Environmental Liabilities
(as defined in subsection (e) below) for the Company under any applicable
Environmental Law that had, or would reasonably be likely to have, a Material
Adverse Effect on the Company.  Neither the Company nor any Company Subsidiary
has engaged in any activity or failed to undertake any activity which action or
failure to act has given, or would reasonably be likely to give, rise to any
Environmental Liabilities or enforcement action by any federal, state or local
regulatory agency or authority, or has resulted, or would reasonably be likely
to result, in any fine or penalty imposed pursuant to any Environmental Law.
Schedule 3.21(b) discloses any known presence of asbestos in or on the

                 (c)      To the knowledge of the Company, no soil or water in
or under any assets currently or formerly held for use or sale by the Company
or any Company Subsidiary is or has been contaminated by any Hazardous
Substance while such assets or premises were owned, leased, operated or
managed, directly or indirectly by the Company or any Company Subsidiary, where
such contamination had, or would be reasonably likely to have, a Material
Adverse Effect on the Company.

                 (d)      There have been no environmental audits and other
similar reports which have been prepared by, for or, to the knowledge of the
Company, concerning the Company or any Company Subsidiary within the five (5)

terms have the following meanings:

                 "Environmental Laws"  shall mean any federal, state or local
         laws, ordinances, codes, regulations, rules, policies and orders
         (including without limitation, Medical Waste Laws) that are intended
         to assure the protection of the environment, or that classify,

         to, or list or define air, water, groundwater, solid waste, hazardous,
         toxic, or radioactive substances, materials, wastes, pollutants or
         contaminants, or which are intended to assure the safety of employees,
         workers or other persons, including the public in each case as in
         effect on the date hereof.

                 "Environmental Liabilities" shall mean all liabilities of the
         Company or any Company Subsidiary, whether contingent or fixed, which
         (i) have arisen, or would reasonably be likely to arise, under
         Environmental Laws and (ii) relate to actions occurring or conditions
         existing on or prior to the date hereof or the Effective Time.

                 "Hazardous Substances" shall mean any toxic or hazardous

filings of any kind or nature necessary to be filed by the Company with any
governmental agency or authority have been properly completed and timely filed

         Section 3.23     Insurance Policies.  The Disclosure Schedules list
and briefly describe the Company's policies of insurance to which the Company
or any Company Subsidiary is a party or under which the Company or any Company
Subsidiary, officer or director thereof is or has been covered at any time
during the last five (5) years preceding the date of this Agreement relating to
the business of the Company or any Company Subsidiary (the "Insurance
Policies").  All of the Insurance Policies are valid, outstanding and
enforceable policies, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies and all premiums with respect thereto which
are due and payable are currently paid.  All Insurance Policies currently
maintained by the Company or any Company Subsidiary ("Current Policies") taken

and operations of the Company and its Affiliates for all risks normally insured
against by a Person carrying on a substantially similar business or businesses

legal and contractual requirements to which the Company or any of its
Affiliates is a party or by which any of them may be bound, and (iii) shall be
maintained in force (including the payment of all premiums and compliance with
their terms) without interruption up to and including the Closing Date.  True,
complete and correct copies





                                       16
<PAGE>   23
of all Insurance Policies have been provided to APP.  Neither the Company nor
any Company Subsidiary nor any officer or director thereof has received any
notice or other written communication from any issuer of any Current Policy
cancelling such policy, materially increasing any deductibles or retained
amounts thereunder, or materially increasing the annual or other premiums
payable thereunder and, to the knowledge of the Company, no such cancellation
or increase of deductibles, retainages or premiums is threatened.  There are no
outstanding claims, settlements or premiums owed against any Insurance Policy,
and all required notices have been given and all known potential or actual
claims under any Insurance Policy have been presented in due and timely
fashion.  Within the five (5) years preceding the Agreement, neither the
Company nor any Company Subsidiary has filed a written application for any
professional liability insurance coverage which has been denied by an insurance
agency or carrier.  The Disclosure Schedules also set forth a list of all
claims under any Insurance Policy in excess of $10,000 per occurrence filed by
the Company or any Company Subsidiary during the immediately preceding
three-year period.  Each Physician Employee has, at all times while a Physician
Employee, maintained or been covered by professional malpractice insurance in
such types and amounts as are customary for such a physician practicing the
same type of medicine in the same geographic area.

         Section 3.24     Accounts Receivable; Payors.

                 (a)      The Disclosure Schedules set forth a list and aging
of all accounts receivable of the Company as of March 31, 1997, which list is
complete, true and accurate in all material respects.  All such accounts
receivable arose in the ordinary course of business and have not been
previously written off as bad debts and, are, to the extent still uncollected,
to the knowledge of the Company collectible in the ordinary course of business,
net of reserves for doubtful and uncollectible accounts shown in the Company
Financial Statements or on the accounting records of the Company (which
reserves are calculated consistent with generally accepted accounting
principles and past practice).

                 (b)      The Disclosure Schedules set forth (i) a true,
correct and complete list of the names and addresses of each Payor of the
Company as of such date, which accounted for more than 5% of the revenues of
the Company in the fiscal year ended December 31, 1996, or which is reasonably
expected to account for more than 5% of the revenues of the Company for the
fiscal year to end December 31, 1997, and (ii) a single line item listing for
all private-pay patients in the aggregate of the Company.  The Company has
satisfactory relations with such Payors set forth in (i) above and none of such
Payors has notified the Company that it intends to discontinue its relationship
with the Company or to deny any payments due from, or any claims for payment
submitted to any such party.

         Section 3.25     Accounts Payable; Suppliers.

                 (a)      The Disclosure Schedules set forth a true and
complete (i) list of the accounts payable of the Company as of March 31, 1997,

non-Physician Employee providers of care to patients) which accounted for a
dollar volume of purchases paid for by the Company in excess of $25,000 for the
fiscal year ended December 31, 1996, or which is reasonably expected to account
for a dollar volume of purchases paid for by the Company in excess of $25,000
for the fiscal year to end December 31, 1997.

         Section 3.26     Inventory.  All items of inventory on the Company
Current Balance Sheet contained in the Company Financial Statements consisted,
and all such items on hand on the date of this Agreement consist, and all such
items on hand at the Effective Time will consist, net of all applicable
reserves with respect thereto (calculated consistent with past practice), of
items of a quality and a quantity usable and saleable in the ordinary course of
the Company's business and conform to generally accepted standards in the
industry of which the Company is a part.  The value of the inventories
reflected on the Company Current Balance Sheet contained in the Company
Financial Statements are net of adequate reserves for damaged, excess, and
unusable items.  Purchase commitments of the Company for inventory





                                       17
<PAGE>   24
are not materially in excess of normal requirements, and none of such purchase
commitments are at prices in excess of prevailing market prices at the time of
such purchase commitment.

        Section 3.27     Licenses, Authorization and Provider Programs.

                 (a)      The Company, and each Physician Employee and other
licensed employee or independent contractor of the Company (i) is the holder of
all valid licenses, approvals, orders, consents, permits, registrations,
qualifications and other rights and authorizations required by law, ordinance,
regulation or ruling of any governmental regulatory authority necessary to

participate in and to receive reimbursement under Titles XVIII and XIX of the
Social Security Act (the "Medicare and Medicaid Programs") and any other
programs funded in whole or in part by federal, state or local entities for
which the Company is eligible and which are listed in the Disclosure Schedules
("Governmental Programs").  The Company, the Stockholders, and each Physician
Employee has a current provider number for such Governmental Programs and with
such private non-governmental programs (including without limitation any
private insurance program) under which the Company is presently receiving
payments directly or indirectly from any Payor for patient care provided by
such Physician Employee, licensed employee or independent contractor (such
non-governmental programs herein referred to as "Private Programs").  A true,
correct and complete list of such licenses, permits and other authorizations
(including, but not limited to verification of Medicare and Medicaid provider
numbers and participating physician contracts under 1842(h) of the Social
Security Act), and provider agreements, is set forth in the Disclosure
Schedules, true, complete and correct copies of which have been provided to
APP.  No violation, default, order or deficiency exists with respect to any of
the items listed in the Disclosure Schedules except for such violations,
defaults, orders or deficiencies which would not be reasonably likely to have a
Material Adverse Effect on the Company, and there is no action pending or to
the Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program,
and no event has occurred which, with or without notice or lapse of time, or
both, would constitute grounds for a violation, order or deficiency with
respect to any of the items listed in the Disclosure Schedules to revoke,
withdraw or suspend any material license to operate its business as is
presently being conducted by it.  To the knowledge of the Company, there has
been no decision not to renew any existing agreement with any provider or Payor
relating to the Company's business as presently being conducted by it.  Neither
the Company nor any Physician Employee (i) has had his/her/its professional
license, Drug Enforcement Agency number, Medicare/Medicaid provider status or
staff privileges at any hospital or diagnostic imaging center suspended,
relinquished, terminated or revoked (including orders that have been entered by
any such entities but stayed), (ii) has been reprimanded in writing, sentenced,
or disciplined by any licensing board, state agency, regulatory body or
authority, hospital, Payor or specialty board (including orders that have been
entered by any such entities but stayed), or (iii) is the subject of an initial
or final determination by any federal or state authority that could result in
any demand or reimbursement under the Medicare, Medicaid or Government Programs
or any exclusion or which monetary penalty under federal or state law or (iv)
has had a final judgment or settlement entered against him/her/it in connection
with a malpractice or similar action.

                 (b)      The Company is not required, or for the 72-month
period prior to the Effective Time was not required, to file any cost reports
or other reports with any Governmental Program or Private Program.

         Section 3.28     Inspections and Investigations.  Neither the right of
the Company, or any Physician Employee, nor the right of any licensed
professional or other individual affiliated with the Company to receive
reimbursements pursuant to any Governmental Program or Private Program has been
terminated or otherwise materially and adversely affected as a result of any
investigation or action whether by any federal or state governmental regulatory
authority or other third party.  No Physician Employee, licensed professional
or other individual affiliated with the business has, during the past three (3)
years prior to the Effective Time, had their professional license or staff
privileges limited, suspended or revoked by any governmental regulatory
authority or agency, hospital, integrated delivery system, trade association,
professional review organization, accrediting organization or certifying agency





                                       18

APP.  There are no outstanding and, to the Company's knowledge, any threatened
disputes or disagreements with respect to any such agreement.

                 (c)      The Company owns or has the legal right to use the
Proprietary Rights without conflicting with, infringing or violating the rights
of any other Person.  No consent of any person will be required for the use
thereof by APP upon consummation of the transactions contemplated hereby and
the Proprietary Rights are freely transferable.  To the knowledge of the
Company, no claim has been asserted by any person to the ownership of or for

all Tax Returns and reports required to be filed with the United States or any

and properly reflect the taxes of the Company for the periods covered thereby.

                 (b)      Payment of Taxes.  Except for such items as the

                 hereto, other than as required to discharge its or their
                 fiduciary duties.

         Section 7.2      Title to Assets; Indebtedness.  As of the Effective
Time, the Company shall (i) except for sales of assets held as inventory, if
any, in the ordinary course of business prior to the Effective Time and except
as otherwise specifically described in the Disclosure Schedules to this
Agreement, have good and valid title to all of its assets free and clear of all
Encumbrances of any nature whatsoever, except for current year ad valorem taxes
and liens which arise by operation of law, and (ii) have no direct or indirect
indebtedness except for indebtedness disclosed in the Company Financial

Company, including, without limitation, deeds, title documents, leases, patient

agree) to consult with the officers, employees (after announcement by the
Company of the Merger to its employees which shall occur no later than three
(3) days subsequent to execution hereof by the Company), accountants, counsel

information not customarily disclosed concerning the business, assets,
liabilities, properties and personnel of the Company, or, without APP's prior
written approval, afford to any Person other than APP and its agents access to
the properties, books or records of the Company.  If the Company receives any
offer or proposal after the date hereof, written or otherwise, of the type
referred to above, the Company shall promptly inform APP of such offer or
proposal, decline such offer and furnish APP with a copy thereof if such offer
or proposal is in writing.

proceedings commenced or threatened against, relating to or involving or
otherwise affecting the Company which, if pending on the date of this
Agreement, would have been required to have been disclosed to APP hereunder or
which relate to the consummation of the transactions contemplated by this

         Section 7.8      Stockholders' Consent.  The Company shall use its
best efforts to obtain the unanimous approval of its Stockholders to the
Merger.  In seeking the approval of its Stockholders, the Company shall provide
each Stockholder with the Form S-4 which shall include information as may be
required by applicable law or as APP shall deem appropriate.  The Board of
Directors of the Company shall recommend the approval of the Merger by the
Stockholders of the Company.  If the Stockholders' approval is not unanimous,
the Company shall give notice to the nonconsenting Stockholders of the action
taken by the consenting Stockholders as may be required by applicable law.

         Section 7.9      Obligations of Company and Stockholders.  Subject to
Section 7.8 hereof, the Company will take all action reasonably necessary to
cause the Company to perform its obligations under this Agreement and all
related agreements and to consummate the Merger and other transactions
contemplated hereby and thereby on the terms and conditions set forth in this
Agreement and such agreements; provided, however, that this covenant shall not
require the Company to make any expenditures that are not expressly set forth
in this Agreement or otherwise contemplated herein.

         Section 7.10     Funding of Accrued Employee Benefits.  The Company
hereby covenants and agrees that it will take whatever steps are necessary to

                                       29
<PAGE>   36
where applicable, or vested accrued benefits for which the Company or any
entity might have any liability whatsoever arising from any tax-qualified plan
as required under applicable law.  The Company acknowledges that the purpose
and intent of this covenant is to assure that APP shall have no liability
whatsoever at any time after the Closing Date with respect to any such
tax-qualified plan, unless such plan is merged with a plan sponsored by APP.

         Section 7.11     Accounting and Tax Matters.  The Company will not
change in any material respect the accounting methods or practices followed by
the Company (including any material change in any assumption underlying, or any
method of calculating, any bad debt, contingency or other reserve), except as
may be required by generally accepted accounting principles.  The Company will
not make any material tax election except in the ordinary course of business
consistent with past practice, change any material tax election already made,
adopt any tax accounting method except in the ordinary course of business
consistent with past practice, change any tax accounting method, enter into any
closing agreement, settle any tax claim or assessment or consent to any tax
claim or assessment or any waiver of the statute of limitations for any such
claim or assessment.  The Company will duly, accurately and timely (without
regard to any extensions of time) file all returns, information statements and
other documents relating to taxes of the Company required to be filed by it,
and pay all taxes required to be paid by it, on or before the Closing Date.

         Section 7.12     Spin-Off Transaction.  The Company shall form,
organize and incorporate NewCo in the state of New York, and the articles or
certificate of incorporation and bylaws of NewCo shall be in form and substance
reasonably satisfactory to APP.  Except for consummating the Spin-Off
Transaction, NewCo shall not commence business until the Closing Date.  On or
prior to the Closing, the Company shall take all actions and execute all
documents, agreements or instruments necessary pursuant to and in compliance
with applicable law to effect the Spin-Off Transaction, including without
limitation, the following:  Prior to the Closing, the Company shall transfer to
NewCo good, valid and marketable title to all of the Company's right, title and
interest in and to the Employee Benefit Plans, all contracts and agreements and
other assets listed on the Disclosure Schedules (to be delivered by the Company
prior to Closing, which schedule will be subject to the approval of APP, which
approval shall not be unreasonably withheld) which by law either cannot be
acquired or cannot be used by APP because they relate to the practice of
medicine or radiology, and shall contribute to NewCo such other consideration
and assets of the Company as may be required under applicable law, in exchange
for the issuance by NewCo of shares of NewCo Common Stock, such shares being
all of the issued and outstanding shares of NewCo Common Stock.  The Company
shall then distribute the shares of NewCo Common Stock to the Stockholders in
proportion to their respective ownership interest in the Company.

         Section 7.13     "F" Reorganization.  The Company shall convert its
corporate status from that of a professional medical corporation to that of a
general business corporation in a transaction which will qualify as a tax-free
transaction under Section 368(a)(2)(F) of the Code (the "F" Reorganization").
The Company shall prepare and execute all documents necessary to effectuate the
"F" Reorganization prior to the Closing.  At or prior to the Closing, the
Company shall cause an amendment to this Agreement to be executed which will
reflect the changes which result from the "F" Reorganization.

         Section 8.1      Consummation of Agreement.  APP will take all action
reasonably necessary to cause the consummation of the transactions contemplated
hereby in accordance with their terms and conditions and take all corporate and
other action necessary to approve the Merger; provided, however, that this

set forth in this Agreement or otherwise contemplated herein.

<PAGE>   37
         Section 8.2      Requirements to Effect the Merger and Acquisitions.

necessary to effect the Merger under applicable law, including without
limitation the filing with the appropriate government officials of all

officers, and permit the Company and their authorized representatives to
inspect and, at the Company's sole expense, make copies of all documents,
records and information with respect to the affairs of APP as the Company and
their representatives may reasonably request, all for the sole purpose of
permitting the Company to become familiar with the business and assets and
liabilities of APP.  No investigation by the Company or the Stockholders shall
diminish or otherwise affect any of the representations, warranties, covenants
or agreements of APP under this Agreement.

         Section 8.4      Notification of Certain Matters.  APP shall promptly
inform the Company in writing of (a) any notice of, or other communication
relating to, a default or event that, with notice or lapse of time or both,
would become a default, received by APP subsequent to the date of this
Agreement and prior to the Effective Time under any contract, agreement or
investment material to APP's condition (financial or otherwise), operations,
assets, liabilities or business and to which it is subject; (b) any material
adverse change in APP's condition (financial or otherwise), operations, assets,
liabilities or business or (c) defaults or disputes regarding Other Agreements.

efforts to establish a qualified plan and trust for NewCo, within the meaning
of Section 401(a) and 501(a), respectively, of the Code ("New Qualified Plan")
that will provide benefits comparable (as determined under Section 401(a)(4) of
the Code) to the benefits provided under the qualified plans referenced in the
Disclosure Schedules, if any, sponsored by the Company as of March 31, 1997.
APP will file for a favorable determination letter from the IRS on the New
Qualified Plan and request a favorable determination from the IRS that NewCo is
not a member of an affiliated service group (as defined in Section 414(m) of
the Code) or a recipient organization of leased employee services (as defined
in Section 414(n) of the Code).  Any benefits provided under the New Qualified
Plan shall be conditioned on a favorable determination letter from the IRS.
Costs associated with the establishment and design of the New Qualified Plan
shall be paid by APP.  The NewCo shall be responsible for funding any
contributions to, or any ongoing administrative costs of, the New Qualified
Plan.

                        Covenants of APP and the Company

         APP and the Company agree as follows:

         Section 9.1      Filings; Other Action.

         (a)     The Company shall cooperate with APP to promptly prepare and
file with the SEC the Registration Statements on Form S-1 and Form S-4 (or
other appropriate Forms) to be filed by APP in connection with its Initial
Public Offering and offering of the shares of APP Common Stock to the Target
Interest Holders pursuant to the transactions contemplated by this Agreement
and the Other Agreements (including the prospectus constituting parts thereof,

APP in the preparation of the Registration Statements and shall furnish all
information concerning the Company and NewCo as may be reasonably requested in
connection with any such action in a timely manner.

         (b)     The Company and APP and each separately represent and warrant
that (i) in the case of the Company, none of the written information or
documents supplied or to be supplied by it specifically





                                       31
<PAGE>   38
for inclusion in the Registration Statements, by exhibit or otherwise and (ii)
in the case of APP, will, at the time the Registration Statements and each
amendment and supplement thereto, if any, becomes effective under the
Securities Act, none of them contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.  The Company shall be entitled to review the
Registration Statements and each of the amendments thereto, if any, prior to
the time each becomes effective under the Securities Act.  The Company shall
have no responsibility for information contained in the Registration Statements
except for information provided by the Company specifically for inclusion
therein.  The Company's review of the Registration Statements shall not
diminish or otherwise affect the representations, covenants and warranties of
APP contained in this Agreement.

         (c)     The Company shall, upon request, furnish APP with all
information concerning itself, its subsidiaries, directors, officers, partners,
Stockholders and NewCo, and such other matters as may be reasonably requested
by APP in connection with the preparation of the Registration Statements and
each of the amendments or supplements thereto, or any other statement, filing,
notice or application made by or on behalf of each such party or any of its
subsidiaries to any governmental entity in connection with the Merger and the
other transactions contemplated by this Agreement.

         Section 9.2      Amendments of Schedules.  Each party hereto agrees
that, with respect to the representations and warranties of such party
contained in this Agreement, such party shall have the continuing obligation
until the Closing to supplement or amend promptly the Disclosure Schedules with
respect to any matter that would have been or would be required to be set forth
or described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on the Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Disclosure Schedule that constitutes or reflects a Material Adverse Effect on
APP may be made unless the Company consents to such amendment or supplement.
For purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 10.1 and 11.1 have
been fulfilled, the Disclosure Schedules hereto shall be deemed to be the
Disclosure Schedules as amended or supplemented pursuant to this Section 9.2.
In the event that the Company seeks to amend or supplement a Disclosure
Schedule pursuant to this Section 9.2 and APP does not consent to such
amendment or supplement, or APP seeks to amend or supplement a Disclosure
Schedule pursuant to this Section 9.2, and the Company does not consent, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
15.1(a) hereof.

         Section 9.3      Actions Contrary to Stated Intent.  No party hereto
will knowingly, either before or after the Merger, take any action that would
prevent the Merger from qualifying as a tax-free exchange within the meaning of
Sections 351 or 368 of the Code, as applicable.

         Section 9.4      Public Announcements.  The parties hereto will
consult with each other before issuing any press release or making any public
statement with respect to this Agreement and the transactions contemplated
hereby and, except as may be required by applicable law, will not issue any
such press release or make any such public statement prior to such
consultation, although the foregoing shall not apply to any disclosure by APP
in any filing with the DOJ, FTC or SEC.

         Section 9.5      Expenses.  Each party to this Agreement shall be
solely responsible for their own fees and expenses with respect to the
transactions contemplated herein including, without limitation, the fees
charged by attorneys, accountants and financial advisors retained by such
parties.  The fees and expenses incurred by the Company and NewCo in connection
with the Merger shall be paid by the Company Stockholders in full immediately
prior to the Closing and such expenses shall be the sole responsibility of the
Stockholders following the Closing Date and not APP.

         Section 9.6      Patient Confidentiality.  APP shall agree to keep all
records and information regarding the patients of the Company and NewCo
confidential in accordance with all applicable laws.

         Section 13.1     Further Instruments of Transfer.  Following the

or the Surviving Corporation shall deliver any further instruments of transfer

         Section 13.2     Merger Tax Covenant.

         (a)     The parties intend that the Merger will qualify as a tax-free
transaction under Section 351 of the Code in which the Company will not
recognize gain or loss, and pursuant to which any gain recognized by a
Stockholder as a result of the Merger will not exceed the amount of any cash
received by a Stockholder in the Merger (a "Reorganization").

         (b)     Both prior to and after the Effective Time, all books and
records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Merger being treated as a Reorganization.
These obligations are excused as to a party required to maintain the books or
file a Tax Return if such party has provided to the other parties a written
opinion of competent tax counsel to the effect that there is not substantial
authority, within the meaning of Section 6662(d)(2)(B)(i) of the Code, to
report the Merger as a Reorganization and such opinion either is furnished
prior to the Effective Time or is based on facts or events not known at the
Effective Time.  Each party shall provide to each other party such tax
information, reports, returns, or schedules as may be reasonably required to
assist such party in accounting for and reporting the Merger as a
Reorganization.

         (c)     The parties agree that no Stockholder shall be liable for any
taxes incurred by the Company and for which APP has successor liability
therefor which arise solely as a result of the Merger or the consummation of
the transactions contemplated hereby; provided that the foregoing shall not
limit





                                       37
<PAGE>   44
or otherwise be deemed a waiver of any right of indemnification under Section
14.1 for a breach of any representation, warranty or covenant of the Company or
any Stockholder.

         Section 13.3     Current Public Information.  APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

                                  ARTICLE XIV

                                    Remedies

         Section 14.1     Indemnification by the Company.  Subject to the terms
and conditions of this Article XIV, the Company agrees to indemnify, defend and
hold APP and its respective directors, officers, stockholders, employees,
agents, attorneys, consultants and Affiliates harmless from and against all
losses, claims, obligations, demands, assessments, penalties, liabilities,
costs, damages, reasonable attorneys' fees and expenses (including, without
limitation, all costs of experts and all costs incidental to or in connection
with any appellate process) (collectively, "Damages") asserted against or
incurred by such individuals and/or entities arising out of or resulting from:

                 (a)      a breach by the Company of any representation or
warranty (without giving effect to any Material Adverse Effect qualifier
contained as part of any such representation or warranty) or covenant of the
Company contained in this Agreement or in any Schedule or certificate delivered
thereunder;

                 (b)      any violation (or alleged violation) by the Company
and/or any of its past or present directors, officers, partners, stockholders,
employees (including, without limitation, any Physician Employee), agents,
attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons
in which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                 (c)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any (i) untrue
statement of material fact in any Registration Statement or any prospectus
forming or part thereof, or any amendment thereof or supplement thereto
relating to the Company (including any Company Subsidiary) or NewCo required to
be stated therein or (ii) failure to state information necessary to make the
statements therein not misleading, which untrue statement or failure to state
information arises or results solely from information provided in writing to
APP or its counsel by the Company or any Stockholder or their agents
specifically for inclusion in any such Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto.

         Section 14.2     Indemnification by APP.  Subject to the terms and
conditions of this Article XIV, APP hereby agrees to indemnify, defend and hold
the Stockholders, the Company and NewCo and their respective directors,
officers, stockholders, employees, agents, attorneys, consultants and
Affiliates harmless from and against all Damages asserted against or incurred
by such individuals and/or entities arising out of or resulting from:

                 (a)      a breach by APP of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of APP contained in
this Agreement or in any schedule or certificate delivered hereunder; and

                 (b)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon





                                       38
<PAGE>   45
any untrue statements of material fact in any Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or required to be stated therein or failure to state information
necessary to make the statements therein not misleading (except for any
liability based upon any actual or alleged untrue statement of material fact or
an omission to state a material fact relating to NewCo, the Company or any
Stockholder which was derived from any information provided in writing by the
Company or a Company Subsidiary or any of their agents contained in the
representations and warranties set forth in this Agreement or any certificate,
exhibit, schedule or instrument required to be delivered under this Agreement.)

                 Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

         Section 14.3     Conditions of Indemnification.  All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                 (a)      Any party claiming indemnification under the
Agreement (an "Indemnified Party") shall promptly (and, in the event, at least
ten (10) days prior to the due date for any responsive pleadings, filings or
other documents) (i) notify the party for whom indemnification is sought (the
"Indemnifying Party) of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying
Party a written notice ("Claim Notice") describing in reasonable detail the
nature of the Third Party Claim, a copy of all papers served with respect to
such claim (if any), an estimate of the amount of Damages attributable to the
Third Party Claim and the basis of the Indemnified Party's request for
indemnification under this Agreement.  The failure to promptly deliver a Claim
Notice shall not relieve any Indemnifying Party of its obligations to any
Indemnified Party with respect to the related Third Party Claim except to the
extent that the resulting delay is materially prejudicial to the defense of
such claim.  Within thirty (30) days after receipt of any Claim Notice (the
"Election Period"), the Indemnifying Party shall notify the Indemnified Party
(x) whether the Indemnifying Party disputes its potential liability to the
Indemnified Party under this Article XIV with respect to such Third Party Claim
and (y) whether the Indemnifying Party desires, at the sole cost and expense of
such Indemnifying Party, to defend the Indemnified Party against such Third
Party Claim.

                 (b)      If the Indemnifying Party notifies the Indemnified
Party within the Election Period that the Indemnifying Party elects to assume
the defense of the Third Party Claim, then the Indemnifying Party shall have
the right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b).  Except as set
forth in Section 14.3(f) below, the Indemnifying Party shall have full control
of such defense and proceedings, including any compromise or settlement
thereof.  The Indemnified Party is hereby authorized, at the sole cost and
expense of the Indemnifying Party (but only if the Indemnified Party is
entitled to indemnification hereunder), to file, during the Election Period,
any motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Party and not prejudicial to the Indemnifying Party.  If requested by the
Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense
of the Indemnifying Party, to cooperate with the Indemnifying Party and their
counsel in contesting any Third Party Claim that the Indemnifying Party elects
to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person.  The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Party pursuant to this Section 14.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Party, then the Indemnified Party may





                                       39
<PAGE>   46
employ separate counsel at the expense of the Indemnifying Party, and upon
written notification thereof, the Indemnifying Party shall not have the right
to assume the defense of such action on behalf of the Indemnified Party;
provided further that the Indemnifying Party shall not, in connection with any
one such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm
of attorneys at any time for the Indemnified Party, which firm shall be
designated in writing by the Indemnified Party.  Notwithstanding the foregoing,
the Indemnifying Party shall be prohibited from confessing or settling any
criminal allegations brought against the Indemnified Party without the express
written consent of the Indemnified Party.

                 (c)      If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 14.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
14.3(b) but fails diligently and promptly to prosecute or settle the Third
Party Claim, then the Indemnified Party shall have the right to defend, at the
sole cost and expense of the Indemnifying Party (if the Indemnified Party is
entitled to indemnification hereunder), the Third Party Claim by all
appropriate proceedings, which proceedings shall be promptly and vigorously
prosecuted by the Indemnified Party to a final conclusion or settled.  The
Indemnified Party shall have full control of such defense and proceedings,
provided, however, that the Indemnified Party may not enter into, without the
Indemnifying Party's consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim.  Notwithstanding the
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes their
potential liability to the Indemnified Party under this Article XIV and if such
dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party
shall not be required to bear the costs and expenses of the Indemnified Party's
defense pursuant to this Section or of the Indemnifying Party's participation
therein at the Indemnified Party's request, and the Indemnified Party shall
reimburse the Indemnifying Party in full for all costs and expenses of such
litigation.  The Indemnifying Party may participate in, but not control, any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 14.3(c), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnifying Party
has been advised by counsel that there may be one or more legal defenses
available to it that are different from or additional to those available to the
Indemnified Party, then the Indemnifying Party may employ separate counsel and
upon written notification thereof, the Indemnified Party shall not have the
right to assume the defense of such action on behalf of the Indemnifying Party.

                 (d)      In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification
under this Agreement.  If the Indemnifying Party does not notify the
Indemnified Party within sixty (60) days from its receipt of the Indemnity
Notice that the Indemnifying Party disputes such claim, the claim specified by
the Indemnified Party in the Indemnity Notice shall be deemed a liability of
the Indemnifying Party hereunder.  If the Indemnifying Party has timely
disputed such claim, as provided above, such dispute shall be resolved by
litigation in an appropriate court of competent jurisdiction if the parties do
not reach a settlement of such dispute within thirty (30) days after notice of
a dispute is given.

                 (e)      Payments of all amounts owing by any Indemnifying
Party pursuant to this Article XIV relating to a Third Party Claim shall be
made within thirty (30) days after the latest of (i) the settlement of such
Third Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.  Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice
period or (ii) the expiration of the period

for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

                 (f)      The Indemnifying Party shall provide the Indemnified
Party with written notice of any firm offer that is made to settle or
compromise a Third Party Claim against an Indemnified Party.  If a firm offer
is made to settle such a claim solely by the payment of money damages and the
Indemnifying Party notifies the Indemnified Party in writing that the
Indemnifying Party agrees to such settlement, but the Indemnified Party elects
not to accept and agree to it, the Indemnified Party may continue to contest or
defend such Third Party Claim and, in such event, the total maximum liability
of the Indemnifying Party to indemnify or otherwise reimburse the Indemnified
Party hereunder with respect to such a claim shall be limited to and shall not
exceed the amount of such settlement offer, plus reasonable out-of-pocket costs
and reasonable expenses (including reasonable attorneys' fees and
disbursements) to the date of notice that the Indemnifying Party desired to
accept such settlement.

                 (g)      Notwithstanding any provision herein to the contrary,
the obligation of an Indemnifying Party to provide indemnification to an
Indemnified Party for breach of any representation or warranty as provided in
Sections 14.1(a) or 14.2(a) hereof shall not take effect unless and until the
Damages asserted against or incurred in the aggregate and on a collective basis
by the Indemnified Parties pursuant to either Section 14.1 or 14.2 (as
applicable) as a result of such a breach or breaches exceeds $100,000.

         Section 14.4     Costs, Expenses and Legal Fees.  Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 14.5     Tax Benefits; Insurance Proceeds.  The total amount
of any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

                                  Termination

agreement of all parties;

                 (b)      at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and
delivered by the Company or any Stockholder pursuant to this Agreement is or
becomes untrue or breached in any material respect or if the Company or any
Stockholder fails to comply in any material respect with any material covenant
or agreement contained herein, and any such misrepresentation, noncompliance or
breach is not cured, waived or eliminated within thirty (30) days after receipt
of written notice thereof;

                 (c)      at any time prior to the Effective Date by the
Company if any representation or warranty of APP contained in this Agreement or
in any certificate or other document executed and delivered by APP pursuant to
this Agreement is or becomes untrue in any material respect of if APP fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

<PAGE>   48
                 (d)      at any time prior to the Effective Date by APP if, as
a result of the conduct of due diligence and regulatory compliance procedures,
APP deems termination to be advisable; or

                 (e)      by APP or the Company if the Merger shall not have
been consummated by September 30, 1997.

         Section 15.2     Effect of Termination.  Except as set forth in
Section 16.3, in the event this Agreement is terminated pursuant to this
Article XV, this Agreement shall forthwith become void.

                                  ARTICLE XVI

                   Nondisclosure of Confidential Information

         Section 16.1     Non-Disclosure Covenant.  The Company and NewCo
recognize and acknowledge that each has in the past, currently has, and in the
future may possibly have, access to certain Confidential Information of APP
that is valuable, special and a unique asset of such entity's business.  APP
acknowledges that it had in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of the Company and
NewCo that is valuable, special and a unique asset of each such business.  The
Company, NewCo and APP, severally, agree that they will not disclose such
Confidential Information to any person, firm, corporation, association or other
entity for any purpose or reason whatsoever, except (a) to authorized
representatives of APP, NewCo and the Company and (b) to counsel and other
advisers to APP, NewCo and the Company provided that such advisers (other than
counsel) agree to the confidentiality provisions of this Section 16.1, unless
(i) such information becomes available to or known by the public generally
through no fault of the Company, NewCo or APP, as the case may be, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii) the Company, NewCo or APP, as the case may be, shall, if
possible, give prior written notice thereof to the Company, NewCo or APP and
provide the Company or APP with the opportunity to contest such disclosure,
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, or
(iv) the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Merger or otherwise.  In the event of a breach
or threatened breach by the Company, on the one hand, and APP, on the other
hand, of the provisions of this Section, APP, NewCo and the Company shall be
entitled to an injunction restraining the other party, as the case may be, from
disclosing, in whole or in part, such Confidential Information.  Nothing herein
shall be construed as prohibiting any of such parties from pursuing any other
available remedy for such breach or threatened breach, including the recovery
of damages.

         Section 16.2     Damages.  Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, NewCo and the Company agree
that, in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

         Section 16.3     Survival.  The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                 Miscellaneous

         Section 17.1     Amendment; Waivers.  This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto.  Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto.  The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 17.2     Assignment.  Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any party hereto,
except by APP to a wholly owned subsidiary of APP; provided that any such
assignment shall not relieve APP of its obligations hereunder.

Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto.  APP
acknowledges and agrees that the rights and remedies of the Company under this
Agreement will be directly available to the Stockholders as third party
beneficiaries of the rights and remedies of the Company under this Agreement,
including, without limitation, the rights and remedies under Article 14 hereof
to indemnification from APP against Damages incurred by the Stockholders
resulting from a breach by APP of any representation, warranty or covenant of
APP contained herein.  Except as provided in the preceding sentence or as
otherwise provided herein, neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party
hereto or thereto any rights or remedies hereunder or thereunder.

contemplated hereby constitute the entire agreement of the parties regarding
the subject matter hereof, and supersede all prior agreements and

         Section 17.5     Severability.  If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 17.6     Survival of Representations, Warranties and
Covenants.  The representations, warranties and covenants contained herein
shall survive the Closing and all statements contained in any certificate,
exhibit or other instrument delivered by or on behalf of the Company, any
Stockholder or APP pursuant to this Agreement shall be deemed to have been
representations and warranties by the Company, such Stockholder and APP.
Notwithstanding any provision in this Agreement to the contrary, the
representations and warranties contained herein shall survive the Closing until
the second anniversary of the Closing Date except that (a) the representations
and warranties set forth in Section 3.21 with respect to environmental matters
shall survive for a period of ten (10) years, (b) the representations and
warranties set forth in Section 3.30 with respect to tax matters shall survive

for a period of six (6) years and (d) solely for purposes of Section 14.1(c)
and Section 14.2(c), and solely to the extent that any party to be indemnified
pursuant to such provisions actually incurs liability under the Securities Act,
the Exchange Act or any other federal or state securities law, the
representations and warranties set forth therein shall survive until the
expiration of any applicable limitations period.

         Section 17.7     Governing Law.  THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

                 (b)      Each share of Company Common Stock held in the

shares of the Company's Common Stock, shall upon surrender of each certificate
or certificates (or completion of appropriate affidavit of lost certificate and
indemnity) receive such allocation of Merger Consideration as determined in
accordance with the provisions of Exhibit B attached hereto; and (ii) until
each certificate or certificates representing Company Common Stock have been
surrendered by the Stockholders, the certificates for Company Common Stock
shall, for all purposes, represent solely the right to receive Merger
Consideration as determined in accordance with the provisions of Exhibit B
attached hereto and Section 2.10 hereof, if applicable.  At the Effective Time,

<PAGE>   13
each share of Company Common Stock converted into Merger Consideration shall by
virtue of the Merger and without any action on the part of the holders thereof,
cease to be outstanding, be cancelled and returned and all shares of APP Common

hereof, if applicable.

Stock as part of the Merger Consideration hereunder shall receive a cash
payment in lieu thereof reflecting such Stockholder's proportionate interest in
a share of APP Common Stock multiplied by the Initial Public Offering Price.

Subsidiary is in good standing in each jurisdiction where the character of the
property owned or leased by it or the nature of its activities makes such
qualification necessary, except where such failure to be so qualified or in
good standing would not have a Material Adverse Effect on the Company.  Copies
of the articles or certificates of incorporation and all amendments thereto of
the Company and each Company Subsidiary and the bylaws of the Company and each
Company Subsidiary, as amended, and copies of the corporate minutes of the
Company, all of which have been or will be made available to APP for review,

case of the corporate minutes, accurately reflect all material proceedings of
the Stockholders and directors of the Company (and all committees thereof).
The stock record books of the Company, which have been or will be made
available to APP for review, contain true, complete and accurate records of the

enforcement of creditors' rights generally, or by general equity principles, or
by public policy.

         Section 3.3      Governmental Authorization.  Other than complying

approval of the Merger and the filing of the Certificates of Merger (as
contemplated by Section 2.3) and any other required documents related to the
Merger, and other than consents, filings or notifications required to be made
or obtained solely by APP or APP Sub (including, without limitation, in

filing to be made by APP, if any), the execution, delivery and performance by
the Company of this Agreement and the agreements provided for herein, and the

Each outstanding share of Company Common Stock has been legally and validly
issued and is fully paid and nonassessable, and was issued pursuant to a valid
exemption from registration under (i) the Securities Act of 1933, as amended,
and (ii) all applicable state securities laws.  No shares of Company Common
Stock are owned by the Company in treasury.  No shares of Company Common Stock
have been issued or disposed of in violation of any preemptive rights, rights
of first refusal or similar rights of any of the Stockholders.  Other than
Company Common Stock, the Company has no securities, bonds, debentures, notes
or other obligations the holders of which have the right to vote (or are
convertible into or exercisable for securities having the right to vote) with
the Stockholders on any matter.

         Section 3.5      Transactions in Capital Stock.  There exist no
Company Rights.  The Company has no obligation (contingent or otherwise) to

Consents.  Subject to approval of this Agreement and the Merger by the
Stockholders of the Company, the execution, delivery and performance by the
Company of this Agreement and any other documents contemplated hereby (with or
without the giving of notice, the lapse of time, or both): (i) do not require
the consent of any governmental or regulatory body or authority or any other

certificate of incorporation or bylaws, (iii) will not conflict with, result in

Effect on the Company; and (v) except as contemplated by this Agreement, will
not create any Encumbrance or restriction upon the Company Common Stock or any
of the assets or properties of the Company.

         Section 3.9      Intentionally omitted.

         Section 3.12     Litigation and Claims.  There are no claims,
lawsuits, actions, arbitrations, administrative or other proceedings,
governmental investigations or inquiries pending or, to the knowledge of the
Company, threatened against, or affecting the Company, any Company Subsidiary,
any Stockholder, the Physician Employees or any other licensed professional or
other individual affiliated with the Company affecting or that would reasonably
be likely to affect the Company Common Stock or the operations, business
condition, (financial or otherwise), or results of operations of the Company
which (i) if successful, may, individually or in the aggregate, have a Material
Adverse Effect on the Company or (ii) could adversely affect the ability of the
Company or any Company Subsidiary to effect the transactions contemplated
hereby, and to the knowledge of the Company there is no basis for any such
action or any state of facts or occurrence of any event which would reasonably
be likely to give rise to the foregoing.  There are no unsatisfied judgments
against the Company or any Company Subsidiary or any licensed professional or
other individual affiliated with the Company or any Company Subsidiary relating
to services provided on behalf of the Company or any Company Subsidiary or any
consent decrees to which any of the foregoing is subject.  Each of the matters,
if any, set forth in this Section 3.12 is fully covered by policies of
insurance of the Company or any Company Subsidiary as in effect on the date
hereof.

         Section 3.13     No Violation of Law.  Neither the Company nor any
Company Subsidiary has been, nor shall be as of the Effective Time (by virtue
of any action, omission to act, contract to which it is a party or any

state or federal law, ordinance, regulation, order, injunction or decree, or
any other requirement of any governmental body, agency, authority or court
binding on it, or relating to its properties, assets or business or its
advertising, sales or pricing practices, except for violations which,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on the Company.

         Section 3.14     Lease Agreements.  The Disclosure Schedules contain a
true, accurate and complete list of all the lease agreements and license
agreements to which the Company or any Company Subsidiary is a party and
pursuant to which the Company or any Company Subsidiary leases (whether as
lessor or lessee) or licenses (whether as licensor or licensee) any real or
personal property related to the operation of its business and which requires
payments in excess of $12,000 per year (the "Lease Agreements").  The Company
has delivered to APP true and complete copies of all of the Lease Agreements.
Each Lease Agreement is valid, effective and in full force in accordance with
its terms, and there is not under any such lease (i) any existing or claimed
material default by the Company or any Company Subsidiary (as applicable) or
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by the Company or any Company Subsidiary
(as applicable) and, individually or in the aggregate, may reasonably result in
a Material Adverse Effect on the Company, or, (ii) to the knowledge of the
Company, any existing material default by any other party under any of the
Lease Agreements or any event of material default or event which with notice or
lapse of time, or both, would constitute a material default by any such party.
To the knowledge of the Company, there is no pending or threatened reassessment
of any property covered by the Lease Agreements.  The Company or any Company
Subsidiary will use reasonable good faith efforts to obtain, prior to the
Effective Time, the consent of each landlord or lessor whose consent is
required to the assignment of the Lease Agreements and will use reasonable good
faith efforts to deliver to APP or APP Sub in writing such consents as are
necessary to effect a valid and binding transfer or assignment of the Company's
or any Company Subsidiary's rights thereunder.  The Company has a good, clear,
valid and enforceable leasehold interest under each of the Lease Agreements.

compensation arrangements set out in 42 U.S.C. Section  1395nn, 42 C.F.R.
Section  1001.952, and any similar applicable state law safe harbor or other

title to all of its properties and assets (real, personal and mixed, tangible

including, without limitation, all the property and assets reflected in the
Company Current Financial Statements; and (ii) owns such rights, interests,
assets and property free and clear of all Encumbrances, title defects or
objections (except for taxes not yet due and payable).  The personal property

and the Company Subsidiaries constitutes the necessary personal property assets
to continue operation of the Company and any Company Subsidiary.

         Section 3.16     Indebtedness for Borrowed Money.  Except for trade
payables incurred in the ordinary course of business, the Company does not have

         Section 3.17     Contracts and Commitments.

                 (a)      The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies,
of each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate
(other than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health
maintenance organization, other managed care organization or other third-party
provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of

conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any

providing notice of sixty (60) days or less.  All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is
with unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP or APP Sub of the
assets and properties to be acquired by APP or APP Sub from the Company, or
which could inhibit or prevent the Company from transferring to or vesting in
APP or APP Sub good and sufficient title to the assets and properties to be
acquired by APP or APP Sub and the Surviving Corporation except where the
failure to transfer would not have a Material Adverse Effect on APP or APP Sub.
In every instance where consent is necessary, the Company shall, on or before
the Closing Date, use reasonable good faith efforts to obtain and deliver to
APP or APP Sub in writing, effective as of the Closing Date, such consents as
are necessary to enable the Surviving Corporation to enjoy all of the rights
now enjoyed by the Company under such contracts.  Any and all such consents





                                       12
<PAGE>   18
shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement.  Notwithstanding the foregoing, the Company shall not transfer to
APP or APP Sub any contracts or agreements relating to the provision of
professional medical services or other such agreements and contracts that APP
consents to in writing to be transferred to NewCo in the Spin-off Transaction.
No contract with a health care provider or Payor has been materially amended or
terminated within the last twelve (12) months.

                 (b)      The Company (i) has not received notice of any plan
or intention of any other party to exercise any right to cancel or terminate
any contract, agreement or instrument required to be disclosed pursuant to
Section 3.17(a), and to the knowledge of the Company there are no fact(s) that
would justify the exercise of such a right; and (ii) does not currently
contemplate, or have reason to believe any other Person currently contemplates,
any amendment or change to any such contract, agreement or instrument.

Company, no basis for any such audit exists which, if conducted would result in
a Material Adverse Effect on the Company;

amended to the date hereof), determination letters, pending determination
letter applications, trust instruments, insurance contracts or policies related
to an Employee Benefit Plan, administrative services contracts, annual reports,
actuarial valuations, summary plan descriptions, summaries of material
modifications, administrative forms and other documents that constitute a part
of or are incident to the administration of the Employee Benefit Plans.  In
addition, the Company has provided or made available to APP a written
description of all existing practices engaged in by the Company that constitute
Employee Benefit Plans.  Subject to the requirements of ERISA, each of the
Employee Benefit Plans can be terminated or amended at will by the Company
without any further liability or obligation on the part of such entity to make
further contributions or payments in connection therewith following such
termination.  No unwritten amendment exists with respect to any Employee
Benefit Plan.

                 (b)      Administration.  Each Employee Benefit Plan has been
administered and maintained in compliance with all applicable laws, rules and
regulations, except where the failure to be in compliance would not,
individually or in the aggregate, result in a Material Adverse Effect.

                 (c)      Examinations.  The Company has not received any
notice that any Employee Benefit Plan is currently the subject of an audit,
investigation, enforcement action or other similar proceeding conducted by any
state or federal agency or authority.

                 (d)      Prohibited Transactions.  No prohibited transactions
(within the meaning of Section 4975 of the Code or Section 406 of ERISA) have
occurred with respect to any Employee Benefit Plan.  There has been no breach
of any duty under ERISA or applicable law (including, without limitation, any
health care contractor requirements or any other tax law requirements, or
conditions to favorable tax treatment, applicable to such plan), which would be
reasonably likely to result, directly or indirectly, (including through any
obligation of indemnification or contribution), in any taxes, penalties or
other liability to APP or any of its Affiliates.

                 (e)      Claims and Litigation.  No pending or, to the
Company's knowledge, threatened, claims, suits or other proceedings exist with
respect to any Employee Benefit Plan other than normal benefit claims filed by
participants or beneficiaries.

determination letter or ruling from the IRS for each of the Employee Benefit
Plans intended to be qualified within the meaning of Section 401(a) or
501(c)(9) of the Code and/or tax-exempt within the meaning of Section 501(a) of
the Code and, to the best knowledge of the Company and each Stockholder, has
been continually qualified under the applicable Section of the Code since the
effective date of such Employee Benefit Plan.  No proceedings exist or, to the
Company's knowledge, have been threatened that could result in the revocation
of any such favorable determination letter or ruling.

                 (g)      Funding Status.  No accumulated funding deficiency
(within the meaning of Section 412 of the Code), whether waived or unwaived,
exists with respect to any Employee Benefit Plan or any plan sponsored by any
member of a controlled group (within the meaning of Section 412(n)(6)(B) of the
Code) in which the Company is a member (a "Controlled Group").  With respect to
each Employee Benefit Plan subject to Title IV of ERISA, the assets of each
such plan are at least equal in value to the present value of accrued benefits
determined on an ongoing basis as of the date hereof.  With respect to each
Employee Benefit Plan described in Section 501(c)(9) of the Code, the assets of
each such plan are at least equal in value to the present value of accrued
benefits, based upon the most recent actuarial valuation as of a date no more
than ninety (90) days prior to the date hereof.  The Disclosure Schedules
contain a complete and accurate statement of all actuarial assumptions applied
to determine the present value of accrued benefits under all Employee Benefit
Plans subject to actuarial assumptions.

                 (h)      Excise Taxes.  Neither the Company nor any member of
a Controlled Group has any liability to pay excise taxes with respect to any
Employee Benefit Plan under applicable provisions of the Code or ERISA.

                 (i)      Multiemployer Plans.  Neither the Company nor any
member of a Controlled Group is or ever has been obligated to contribute to a
multiemployer plan within the meaning of Section 3(37) of ERISA or any other
Employee Benefit Plan which has been subject to Title IV of ERISA or Section
412 of the Code.

                 (j)      PBGC.  No facts or circumstances are known to the
Company that would result in the imposition of liability against APP, APP Sub
or any of its Affiliates by the Pension Benefit Guaranty Corporation ("PBGC")
as a result of any act or omission by the Company or any member of a Controlled
Group.  No reportable event (within the meaning of Section 4043 of ERISA) for
which the notice requirement has not been waived has occurred with respect to
any Employee Benefit Plan subject to the requirements of Title IV of ERISA.

                 (k)      Retirees.  The Company has no obligation or
commitment to provide medical, dental or life insurance benefits to or on
behalf of any of its employees who may retire or any of its former employees
who have retired except as may be required pursuant to the continuation of
coverage provisions of Section 4980B of the Code and the applicable provisions
of ERISA.

                 (l)      Other Compensation Arrangements.  Neither the Company
nor, to the Company's knowledge, any Stockholder or Physician Employee is a
party to any compensation or debt arrangement with any Person relating to the
provision of health care related services other than arrangements with the
Company.

         Section 3.21     Environmental Matters.

                 (a)      Neither the Company nor any Company Subsidiary has,

Environmental Law that had, or would





                                       15
<PAGE>   21
reasonably be likely to have, a Material Adverse Effect on the Company.
Neither the Company nor any Company Subsidiary has engaged in any activity or
failed to undertake any activity which action or failure to act has given, or
would reasonably be likely to give, rise to any Environmental Liabilities or
enforcement action by any federal, state or local regulatory agency or

fine or penalty imposed pursuant to any Environmental Law.  The Disclosure

or under any assets currently or formerly held for use or sale by the Company
or any Company Subsidiary is or has been contaminated by any Hazardous
Substance while such assets or premises were owned, leased, operated or
managed, directly or indirectly by the Company or any Company Subsidiary, where
such contamination had, or would be reasonably likely to have, a Material
Adverse Effect on the Company.

                 (d)      There have been no environmental audits and other
similar reports which have been prepared by, for or, to the knowledge of the
Company, concerning the Company or any Company Subsidiary within the five (5)

real property now or previously owned or leased by the Company, any Company
Subsidiary or any of its predecessors, true and complete copies of which have

         Section 3.22     Filing Reports.  All returns, reports, plans and
filings of any kind or nature necessary to be filed by the Company with any
governmental agency or authority have been properly completed and timely filed

         Section 3.23     Insurance Policies.  The Disclosure Schedules list
and briefly describe the Company's policies of insurance to which the Company
or any Company Subsidiary is a party or under which the Company or any Company
Subsidiary, officer or director thereof is or has been covered at any time
during the last five (5) years preceding the date of this Agreement relating to
the business of the Company or any Company Subsidiary (the "Insurance
Policies").  All of the Insurance Policies are valid, outstanding and

insolvency or





                                       16
<PAGE>   22
similar laws affecting creditors' rights generally or the availability of
equitable remedies and all premiums with respect thereto which are due and
payable are currently paid.  All Insurance Policies currently maintained by the
Company or any Company Subsidiary ("Current Policies") taken together, (i)
provide adequate insurance coverage for the assets, properties and operations
of the Company and its Affiliates for all risks normally insured against by a
Person carrying on a substantially similar business or businesses as the
Company and its Affiliates, (ii) are sufficient for compliance with legal and
contractual requirements to which the Company or any of its Affiliates is a
party or by which any of them may be bound, and (iii) shall be maintained in
force (including the payment of all premiums and compliance with their terms)
without interruption up to and including the Closing Date.  True, complete and
correct copies of all Insurance Policies have been provided to APP.  Neither
the Company nor any Company Subsidiary nor any officer or director thereof has
received any notice or other written communication from any issuer of any
Current Policy cancelling such policy, materially increasing any deductibles or
retained amounts thereunder, or materially increasing the annual or other
premiums payable thereunder and, to the knowledge of the Company, no such
cancellation or increase of deductibles, retainages or premiums is threatened.
There are no outstanding claims, settlements or premiums owed against any
Insurance Policy, and all required notices have been given and all known
potential or actual claims under any Insurance Policy have been presented in
due and timely fashion.  Within the five (5) years preceding the Agreement,

for any professional liability insurance coverage which has been denied by an
insurance agency or carrier.  The Disclosure Schedules also set forth a list of
all claims under any Insurance Policy in excess of $10,000 per occurrence filed
by the Company or any Company Subsidiary during the immediately preceding
three-year period.  Each Physician Employee has, at all times while a Physician
Employee, maintained or been covered by professional malpractice insurance in
such types and amounts as are customary for such a physician practicing the
same type of medicine in the same geographic area.

                 (a)      The Disclosure Schedules set forth a list and aging
of all accounts receivable of the Company as of March 31, 1997, which list is
complete, true and accurate in all material respects.  All such accounts
receivable arose in the ordinary course of business and have not been
previously written off as bad debts and, are, to the extent still uncollected,
to the knowledge of the Company collectible in the ordinary course of business,
net of reserves for doubtful and uncollectible accounts shown in the Company
Financial Statements or on the accounting records of the Company (which
reserves are calculated consistent with generally accepted accounting
principles and past practice).

                 (b)      The Disclosure Schedules set forth (i) a true,
correct and complete list of the names and addresses of each Payor of the
Company as of such date, which accounted for more than 5% of the revenues of

expected to account for more than 5% of the revenues of the Company for the
fiscal year to end December 31, 1997, and (ii) a single line item listing for
all private-pay patients in the aggregate of the Company.  The Company has
satisfactory relations with such Payors set forth in (i) above and none of such
Payors has notified the Company that it intends to discontinue its relationship
with the Company or to deny any payments due from, or any claims for payment
submitted to any such party.

         Section 3.25     Accounts Payable; Suppliers.

                 (a)      The Disclosure Schedules set forth a true and
complete (i) list of the accounts payable of the Company as of March 31, 1997,

non-Physician Employee providers of care to patients) which accounted for a
dollar volume of purchases paid for by the Company in excess of $25,000 for the
fiscal year ended December 31, 1996, or which is reasonably expected to account
for a dollar volume of purchases paid for by the Company in excess of $25,000

Current Balance Sheet contained in the Company Financial Statements consisted,
and all such items on hand on the date of this Agreement consist, and all such
items on hand at the Effective Time will consist, net of all applicable
reserves with respect thereto (calculated consistent with past practice), of
items of a quality and a quantity usable and saleable in the ordinary course of
the Company's business and conform to generally accepted standards in the
industry of which the Company is a part.  The value of the inventories
reflected on the Company Current Balance Sheet contained in the Company
Financial Statements are net of adequate reserves for damaged, excess, and
unusable items.  Purchase commitments of the Company for inventory are not
materially in excess of normal requirements, and none of such purchase
commitments are at prices in excess of prevailing market prices at the time of
such purchase commitment.

        Section 3.27     Licenses, Authorization and Provider Programs.

                 (a)      The Company, and each Physician Employee and other
licensed employee or independent contractor of the Company (i) is the holder of

Social Security Act (the "Medicare and Medicaid Programs") and any other
programs funded in whole or in part by federal, state or local entities for

("Governmental Programs").  The Company, the Stockholders, and each Physician
Employee has a current provider number for such Governmental Programs and with
such private non-governmental programs (including without limitation any
private insurance program) under which the Company is presently receiving
payments directly or indirectly from any Payor for patient care provided by
such Physician Employee, licensed employee or independent contractor (such
non-governmental programs herein referred to as "Private Programs").  A true,
correct and complete list of such licenses, permits and other authorizations
(including, but not limited to verification of Medicare and Medicaid provider
numbers and participating physician contracts under 1842(h) of the Social
Security Act), and provider agreements, is set forth in the Disclosure
Schedules, true, complete and correct copies of which have been provided to
APP.  No violation, default, order or deficiency exists with respect to any of
the items listed in the Disclosure Schedules except for such violations,
defaults, orders or deficiencies which would not be reasonably likely to have a
Material Adverse Effect on the Company, and there is no action pending or to
the Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program,
and no event has occurred which, with or without notice or lapse of time, or
both, would constitute grounds for a violation, order or deficiency with
respect to any of the items listed in the Disclosure Schedules to revoke,
withdraw or suspend any material license to operate its business as is
presently being conducted by it.  To the knowledge of the Company, there has
been no decision not to renew any existing agreement with any provider or Payor
relating to the Company's business as presently being conducted by it.  Neither
the Company nor any Physician Employee (i) has had his/her/its professional

or disciplined by any licensing board, state agency, regulatory body or
authority, hospital, Payor or specialty board (including orders that have been

any demand or reimbursement under the Medicare, Medicaid or Government Programs
or any exclusion or which monetary penalty under federal or state law or (iv)
has had a final judgment or settlement entered against him/her/it in connection
with a malpractice or similar action.

                 (b)      The Company is not required, or for the 72-month
period prior to the Effective Time was not required, to file any cost reports
or other reports with any Governmental Program or Private Program.

the Company, or any Physician Employee, nor the right of any licensed
professional or other individual affiliated with the Company to receive
reimbursements pursuant to any Governmental Program or Private Program has been
terminated or otherwise materially and adversely affected as a result of any
investigation or action whether by any federal or state governmental regulatory
authority or other third party.  No Physician Employee, licensed professional
or other individual affiliated with the business has, during the past three (3)
years prior to the Effective Time, had their professional license or staff
privileges limited, suspended or revoked by any governmental regulatory
authority or agency, hospital, integrated delivery system, trade association,
professional review organization, accrediting organization or certifying agency

                     Representations and Warranties of APP

         As inducement to the Company and the Stockholders to enter into this
Agreement and to consummate the Merger, and except as set forth in the
Disclosure Schedules attached hereto and incorporated herein by this reference,
APP represents and warrants to the Company and the Stockholders both as of the
date hereof and as of the Effective Time as follows:

is a corporation duly organized, validly existing and in good standing under
the laws of the state of Delaware, with all requisite corporate power and
authority to own, operate and lease its assets and properties and to carry on
its business as currently conducted.  APP is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, except where such failure to be so
qualified or in good standing would not have a Material Adverse Effect on APP.
Copies of the certificate of incorporation and all amendments thereto of APP
and the bylaws of APP, as amended, and copies of the corporate minutes of APP
regarding the Merger and the transactions contemplated hereby, all of which
have been or will be made available to the Company for review, are true,
correct and complete as in effect on the date of this Agreement and accurately
reflect all material proceedings of the stockholders and directors of APP (and
all committees thereof) regarding the Merger and the transactions contemplated
hereby.  The stock record books of APP, which have been or will be made
available to the Company for review, contain true, complete and accurate
records of the stock ownership of APP and the transfer of the shares of its
capital stock.

         Section 4.2      Authorization and Validity.  APP has all requisite
corporate power to execute and deliver this Agreement and the Other Agreements
and to consummate the Merger and the transactions contemplated hereby.  The

of the transactions contemplated hereby and thereby are within APP's corporate
powers and have been duly authorized by all necessary action on the part of
APP's Board of Directors.  This Agreement has and the Other Agreements have
been duly executed by APP.  This Agreement and all other agreements and
obligations entered into and undertaken in connection with the Merger and the
transactions contemplated hereby to which APP is a party constitute, or upon
execution will constitute, valid and binding agreements of APP, enforceable
against it in accordance with their respective terms, except as may be limited
by bankruptcy or other laws affecting creditors' rights generally, or by
general equity principles, or by public policy.

         Section 4.3      Governmental Authorization.  Other than complying
with the provisions of the applicable state corporate laws regarding the
approval of the Merger and the filing of the Certificates of Merger and any
other required documents related to the Merger, and other than consents,
filings or notifications required to be made or obtained solely by the Company,
the execution, delivery and performance by APP of this Agreement and the
agreements provided for herein, and the consummation of the Merger and the
transactions contemplated hereby and thereby by APP requires no action by or in
respect of, or filing with, any governmental body, agency, official or
authority.

         Section 4.4      Capitalization.  The authorized capital stock of APP
consists of 20,000,000 shares of APP Common Stock, of which 2,000,000 shares
are issued and outstanding and 10,000,000 shares of APP Preferred Stock, none
of which are outstanding.  Each outstanding share of APP Common Stock has been
legally and validly issued and is fully paid and nonassessable, and was issued
pursuant to a valid exemption from registration under (i) the Securities Act of
1933, as amended, and (ii) all applicable state securities laws.  No shares of
capital stock are owned by APP in treasury.  No shares of capital stock of APP
have been issued or disposed of in violation of the preemptive rights, rights
of first refusal or similar rights of any stockholders of APP.  APP has no

right to vote (or are convertible into or exercisable for securities having the
right to vote) with the stockholders of APP on any matter.  There exist no
options, warrants,

subscriptions, calls, commitments or other rights to purchase, or securities
convertible into or exchangeable for, any of the authorized or outstanding
securities of APP and no option, warrant, subscription, call, or commitment or
commission right of any kind exists which obligates APP to issue any of its
authorized but unissued capital stock.  APP has no obligation (contingent or
otherwise) to purchase, redeem or otherwise acquire any of its equity
securities or any interests therein or to pay any dividend or make any
distribution in respect thereof.

         Section 4.5      Subsidiaries and Investments.  APP does not own,
directly or indirectly, any capital stock or other equity, ownership or
proprietary interest in any corporation, partnership, association, trust, joint

Consents.  The execution, delivery and performance of this Agreement by APP and
any other documents contemplated hereby (with or without the giving of notice,
the lapse of time, or both): (i) does not require the consent of any
governmental or regulatory body or authority or any other third party except
for such consents, for which the failure to obtain would not result in a
Material Adverse Effect on APP; (ii) will not conflict with any provision of
APP's certificate of incorporation or bylaws; (iii) will not conflict with,

regulation, ruling, judgment, order or injunction of any court or governmental

properties are bound except for such conflict, termination, breach or default,
the occurrence of which would not result in a Material Adverse Effect on APP;
and (v) will not create any Encumbrance or restriction upon APP Common Stock or
any of the assets or properties of APP.  The financial statements of APP

with generally accepted accounting principles consistently applied (except as

contemplated by this Agreement, since March 31, 1997, there has not been (i)
any change in the working capital, condition (financial or otherwise), assets,

which it is a party or any occurrence or state of facts whatsoever), in
violation of any applicable local, state or federal law, ordinance, regulation,
order, injunction or decree, or any other requirement of any governmental body,

be conducted in such a manner as to minimize the disruption to the Company's
ongoing business operations.

         Section 7.4      Acquisition Proposals.  The Company shall not, and

best efforts to restore the relationship.

         Section 7.7      Intentionally omitted.

         Section 7.8      Stockholders' Consent.  The Company shall use its
best efforts to obtain the unanimous approval of its Stockholders to the
Merger.  In seeking the approval of its Stockholders, the Company shall provide
each Stockholder with the Form S-4 which shall include information as may be
required by applicable law or as APP shall deem appropriate.  The Board of
Directors of the Company shall recommend the approval of the Merger by the
Stockholders of the Company.  If the Stockholders' approval is not unanimous,
the Company shall give notice to the nonconsenting Stockholders of the action
taken by the consenting Stockholders as may be required by applicable law.

         Section 7.9      Obligations of Company and Stockholders.  Subject to
Section 7.8 hereof, the Company will take all action reasonably necessary to
cause the Company to perform its obligations under this Agreement and all
related agreements and to consummate the Merger and other transactions
contemplated hereby and thereby on the terms and conditions set forth in this
Agreement and such agreements; provided, however, that this covenant shall not
require the Company to make any expenditures that are not expressly set forth

hereby covenants and agrees that it will take whatever steps are necessary to
pay for or fund completely any accrued benefits, where applicable, or vested
accrued benefits for which the Company or any entity might have any liability
whatsoever arising from any tax-qualified plan as required under applicable
law.  The Company acknowledges that the purpose and intent of this covenant is
to assure that APP Sub shall have no liability whatsoever at any time after the
Closing Date with respect to any such tax-qualified plan, unless such plan is
merged with a plan sponsored by APP or APP Sub.

         Section 7.11     Accounting and Tax Matters.  The Company will not
change in any material respect the accounting methods or practices followed by
the Company (including any material change in any assumption underlying, or any
method of calculating, any bad debt, contingency or other reserve), except as

not make any material tax election except in the ordinary course of business
consistent with past practice, change any material tax election already made,
adopt any tax accounting method except in the ordinary course of business
consistent with past practice, change any tax accounting method, enter into any
closing agreement, settle any tax claim or assessment or consent to any tax
claim or assessment or any waiver of the statute of limitations for any such
claim or assessment.  The Company will duly, accurately and timely (without
regard to any extensions of time) file all returns, information statements and
other documents relating to taxes of the Company required to be filed by it,
and pay all taxes required to be paid by it, on or before the Closing Date.

         Section 7.12     Spin-Off Transaction.  The Company shall form,
organize and incorporate NewCo in the state of California, and the articles or

contracts and agreements and other assets listed on the Disclosure Schedules
(to be delivered by the Company prior to Closing, which schedule will be
subject to the approval of APP, which approval shall not be unreasonably
withheld) which by law either cannot be acquired or cannot be used by APP
because they relate to the practice of medicine or radiology, and shall
contribute to NewCo such other consideration and assets of the Company as may
be required under applicable law, in exchange for the issuance by NewCo of
shares of NewCo Common Stock, such shares being all of the issued and
outstanding shares of NewCo Common Stock.  The Company shall then distribute
the shares of NewCo Common Stock to the Stockholders in proportion to their
respective ownership interest in the Company.

all action reasonably necessary to cause the consummation of the transactions
contemplated hereby in accordance with their terms and conditions and take all

that are not expressly set forth in this Agreement or otherwise contemplated
herein.

         Section 8.2      Requirements to Effect the Merger and Acquisitions.
APP and APP Sub will use their best efforts to take, or cause to be taken, all

during normal business hours and on reasonable notice, permit the Company and
its authorized representatives of the Company reasonable access to, and make
available for inspection, all of the assets and business of APP and APP Sub,
including its executive officers, and permit the Company and their authorized
representatives to inspect and, at the Company's sole expense, make copies of
all documents, records and information with respect to the affairs of APP and
APP Sub as the Company and their representatives may reasonably request, all
for the sole purpose of permitting the Company to become familiar with the
business and assets and liabilities of APP and APP Sub.  No investigation by
the Company or the Stockholders shall diminish or otherwise affect any of the
representations, warranties, covenants or agreements of APP under this
Agreement.

         Section 8.4      Notification of Certain Matters.  APP and APP Sub
shall promptly inform the Company in writing of (a) any notice of, or other
communication relating to, a default or event that, with notice or lapse of

this Agreement and prior to the Effective Time under any contract, agreement or
investment material to APP's or APP Sub's condition (financial or otherwise),

under Section 401(a)(4) of the Code) to the benefits provided under the
qualified plans referenced in the Disclosure Schedules, if any, sponsored by
the Company as of March 31, 1997.  APP will file for a favorable determination
letter from the IRS on the New Qualified Plan and request a favorable
determination from the IRS that NewCo is not a member of an affiliated service
group (as defined in Section 414(m) of the Code) or a recipient organization of
leased employee services (as defined in Section 414(n) of the Code).  Any
benefits provided under the New Qualified Plan shall be conditioned on a
favorable determination letter from the IRS.  Costs associated with the
establishment and design of the





                                       31

                   Covenants of APP, APP Sub and the Company

         APP, APP Sub and the Company agree as follows:

         Section 9.1      Filings; Other Action.

         (a)     The Company shall cooperate with APP and APP Sub to promptly
prepare and file with the SEC the Registration Statements on Form S-1 and Form
S-4 (or other appropriate Forms) to be filed by APP in connection with its
Initial Public Offering and offering of the shares of APP Common Stock to the
Target Interest Holders pursuant to the transactions contemplated by this
Agreement and the Other Agreements (including the prospectus constituting parts
thereof, the "Registration Statements").  APP shall obtain all necessary state
securities law or "Blue Sky" permits and approvals required to carry out the
transactions contemplated by this Agreement.  The Company shall cooperate with
APP in the preparation of the Registration Statements and shall furnish all
information concerning the Company and NewCo as may be reasonably requested in
connection with any such action in a timely manner.

         (b)     The Company, APP and APP Sub and each separately represent and
warrant that (i) in the case of the Company, none of the written information or
documents supplied or to be supplied by it specifically for inclusion in the
Registration Statements, by exhibit or otherwise and (ii) in the case of APP or
APP Sub, will, at the time the Registration Statements and each amendment and
supplement thereto, if any, becomes effective under the Securities Act, none of
them contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.  The Company shall be entitled to review the Registration
Statements and each of the amendments thereto, if any, prior to the time each
becomes effective under the Securities Act.  The Company shall have no
responsibility for information contained in the Registration Statements except
for information provided by the Company specifically for inclusion therein.
The Company's review of the Registration Statements shall not diminish or
otherwise affect the representations, covenants and warranties of APP and APP
Sub contained in this Agreement.

         (c)     The Company shall, upon request, furnish APP with all
information concerning itself, its subsidiaries, directors, officers, partners,
Stockholders and NewCo, and such other matters as may be reasonably requested
by APP in connection with the preparation of the Registration Statements and
each of the amendments or supplements thereto, or any other statement, filing,
notice or application made by or on behalf of each such party or any of its
subsidiaries to any governmental entity in connection with the Merger and the
other transactions contemplated by this Agreement.

         Section 9.2      Amendments of Disclosure Schedules.  Each party
hereto agrees that, with respect to the representations and warranties of such
party contained in this Agreement, such party shall have the continuing
obligation until the Closing to supplement or amend promptly the Disclosure
Schedules with respect to any matter that would have been or would be required
to be set forth or described in the Disclosure Schedules in order to not
materially breach any representation, warranty or covenant of such party
contained herein; provided that no amendment or supplement to a Disclosure
Schedule that constitutes or reflects a Material Adverse Effect on the Company
may be made unless APP consents to such amendment or supplement, and no
amendment or supplement to a Schedule that constitutes or reflects a Material
Adverse Effect on APP may be made unless the Company consents to such amendment
or supplement.  For purposes of this Agreement, including without limitation
for purposes of determining whether the conditions set forth in Sections 10.1
and 11.1 have been fulfilled, the Disclosure Schedules hereto shall be deemed
to be the Disclosure Schedules as amended or supplemented pursuant to this
Section 9.2.  In the event that the Company seeks to amend or supplement a
Disclosure Schedule pursuant to this Section 9.2 and APP does not consent to
such amendment or supplement, or APP seeks to amend





                                       32
<PAGE>   38
or supplement a Disclosure Schedule pursuant to this Section 9.2, and the
Company does not consent, this Agreement shall be deemed terminated by mutual
consent as set forth in Section 15.1(a) hereof.

         Section 9.3      Actions Contrary to Stated Intent.  No party hereto
will knowingly, either before or after the Merger, take any action that would
prevent the Merger from qualifying as a tax-free exchange within the meaning of
Section 351 of the Code.

         Section 9.4      Public Announcements.  The parties hereto will
consult with each other before issuing any press release or making any public
statement with respect to this Agreement and the transactions contemplated
hereby and, except as may be required by applicable law, will not issue any
such press release or make any such public statement prior to such
consultation, although the foregoing shall not apply to any disclosure by APP
in any filing with the DOJ, FTC or SEC.

         Section 9.5      Expenses.  Each party to this Agreement shall be
solely responsible for their own fees and expenses with respect to the
transactions contemplated herein including, without limitation, the fees
charged by attorneys, accountants and financial advisors retained by such
parties.  The fees and expenses incurred by the Company and NewCo in connection
with the Merger shall be paid by the Company in full immediately prior to the
Closing and such expenses shall be the sole responsibility of the Stockholders
following the Closing Date and not APP.

         Section 9.6      Patient Confidentiality.  APP and APP Sub shall agree
to keep all records and information regarding the patients of the Company and
NewCo confidential in accordance with all applicable laws.

         Section 9.7      Registration Statements.  APP shall prepare and file
the Registration Statements with the SEC, and shall use its reasonable good
faith efforts to cause the Registration Statements to become effective under

issuance of the shares of APP Common Stock upon consummation of the Merger.

                              Post Closing Matters

         Section 13.1     Further Instruments of Transfer.  Following the
Closing, at the request of APP or the Surviving Corporation and at APP's sole
cost and expense, the Stockholders and the Company shall deliver any further

or the Surviving Corporation shall deliver any further instruments of transfer
and take all reasonable action as may be necessary and appropriate to carry out
the purpose and intent of this Agreement.

         Section 13.2     Merger Tax Covenant.

         (a)     The parties intend that the Merger will qualify as a tax-free
transaction under Section 351 of the Code in which the Company will not
recognize gain or loss, and pursuant to which any gain recognized by a
Stockholder as a result of the Merger will not exceed the amount of any cash
received by a Stockholder in the Merger (a "Reorganization").

records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Merger being treated as a Reorganization.
These obligations are excused as to a party required to maintain the books or
file a Tax Return if such party has provided to the other parties a written
opinion of competent tax counsel to the effect that there is not substantial
authority, within the meaning of Section 6662(d)(2)(B)(i) of the Code, to
report the Merger as a Reorganization and such opinion either is furnished
prior to the Effective Time or is based on facts or events not known at the
Effective Time.  Each party shall provide to each other party such tax
information, reports, returns, or schedules as may be reasonably required to
assist such party in accounting for and reporting the Merger as a
Reorganization.

         (c)     The parties agree that no Stockholder shall be liable for any
taxes incurred by the Company and for which APP has successor liability
therefor which arise solely as a result of the Merger or the consummation of
the transactions contemplated hereby; provided that the foregoing shall not
limit or otherwise be deemed a waiver of any right of indemnification under
Section 14.1 for a breach of any representation, warranty or covenant of the
Company or any Stockholder.

         Section 13.3     Current Public Information.  APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

                                    Remedies

harmless from and against all losses, claims, obligations, demands,
assessments, penalties, liabilities, costs, damages, reasonable attorneys' fees
and expenses (including, without limitation, all costs of experts and all costs
incidental to or in connection with any appellate process) (collectively,
"Damages") asserted against or incurred by such individuals and/or entities
arising out of or resulting from:

                 (a)      a breach by the Company of any representation or
warranty (without giving effect to any Material Adverse Effect qualifier
contained as part of any such representation or warranty) or covenant of the
Company contained in this Agreement or in any Schedule or certificate delivered
thereunder;

                 (b)      any violation (or alleged violation) by the Company

attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons
in which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                 (c)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any (i) untrue
statement of a material fact in any Registration Statement or any prospectus
forming or part thereof, or any amendment thereof or supplement thereto
relating to the Company (including any Company Subsidiary) or NewCo required to
be stated therein or (ii) failure to state information necessary to make the
statements therein not misleading, which untrue statement or failure to state
information arises or results solely from information provided in writing to
APP or its counsel by the Company or any Stockholder or their agents
specifically for inclusion in any such Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto.

         Section 14.2     Indemnification by APP and APP Sub.  Subject to the
terms and conditions of this Article XIV, APP and APP Sub jointly and severally
hereby agree to indemnify, defend and hold the Stockholders, the Company and
NewCo and their respective directors, officers, stockholders, employees,
agents, attorneys, consultants and Affiliates harmless from and against all
Damages asserted against or incurred by such individuals and/or entities
arising out of or resulting from:

                 (a)      a breach by APP or APP Sub of any representation or
warranty (without giving effect to any Material Adverse Effect qualifier
contained as part of any such representation or warranty) or covenant of APP or
APP Sub contained in this Agreement or in any schedule or certificate delivered
hereunder; and

                 (b)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any untrue statements
of material fact in any Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or required to be
stated therein or failure to state information necessary to make the statements
therein not misleading (except for any liability based upon any actual or
alleged untrue statement of material fact or an omission to state a material
fact relating to NewCo, the Company or any Stockholder to the extent derived
from any information provided in writing by the Company or a Company Subsidiary
or any of their agents contained in the representations and warranties set
forth in this Agreement or any certificate, exhibit, schedule or instrument
required to be delivered under this Agreement.)

                 Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

<PAGE>   45
         Section 14.3     Conditions of Indemnification.  All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                 (a)      Any party claiming indemnification under the
Agreement (an "Indemnified Party") shall promptly (and, in the event, at least
ten (10) days prior to the due date for any responsive pleadings, filings or
other documents) (i) notify the party for whom indemnification is sought (the
"Indemnifying Party) of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying
Party a written notice ("Claim Notice") describing in reasonable detail the
nature of the Third Party Claim, a copy of all papers served with respect to
such claim (if any), an estimate of the amount of Damages attributable to the
Third Party Claim and the basis of the Indemnified Party's request for
indemnification under this Agreement.  The failure to promptly deliver a Claim
Notice shall not relieve any Indemnifying Party of its obligations to any
Indemnified Party with respect to the related Third Party Claim except to the
extent that the resulting delay is materially prejudicial to the defense of
such claim.  Within thirty (30) days after receipt of any Claim Notice (the
"Election Period"), the Indemnifying Party shall notify the Indemnified Party
(x) whether the Indemnifying Party disputes its potential liability to the
Indemnified Party under this Article XIV with respect to such Third Party Claim
and (y) whether the Indemnifying Party desires, at the sole cost and expense of
such Indemnifying Party, to defend the Indemnified Party against such Third
Party Claim.

                 (b)      If the Indemnifying Party notifies the Indemnified
Party within the Election Period that the Indemnifying Party elects to assume
the defense of the Third Party Claim, then the Indemnifying Party shall have
the right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b).  Except as set
forth in Section 14.3(f) below, the Indemnifying Party shall have full control
of such defense and proceedings, including any compromise or settlement
thereof.  The Indemnified Party is hereby authorized, at the sole cost and
expense of the Indemnifying Party (but only if the Indemnified Party is
entitled to indemnification hereunder), to file, during the Election Period,
any motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Party and not prejudicial to the Indemnifying Party.  If requested by the
Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense
of the Indemnifying Party, to cooperate with the Indemnifying Party and their
counsel in contesting any Third Party Claim that the Indemnifying Party elects
to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person.  The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Party pursuant to this Section 14.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Party, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Party, and upon written
notification thereof, the Indemnifying Party shall not have the right to assume
the defense of such action on behalf of the Indemnified Party; provided further
that the Indemnifying Party shall not, in connection with any one such action
or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party.  Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                 (c)      If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 14.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
14.3(b) but fails diligently and promptly to prosecute or settle the Third
Party Claim, then the Indemnified Party shall have





                                       40
<PAGE>   46
the right to defend, at the sole cost and expense of the Indemnifying Party (if
the Indemnified Party is entitled to indemnification hereunder), the Third
Party Claim by all appropriate proceedings, which proceedings shall be promptly
and vigorously prosecuted by the Indemnified Party to a final conclusion or
settled.  The Indemnified Party shall have full control of such defense and
proceedings, provided, however, that the Indemnified Party may not enter into,
without the Indemnifying Party's consent, which shall not be unreasonably
withheld, any compromise or settlement of such Third Party Claim.
Notwithstanding the foregoing, if the Indemnifying Party has delivered a
written notice to the Indemnified Party to the effect that the Indemnifying
Party disputes their potential liability to the Indemnified Party under this
Article XIV and if such dispute is resolved in favor of the Indemnifying Party,
the Indemnifying Party shall not be required to bear the costs and expenses of
the Indemnified Party's defense pursuant to this Section or of the Indemnifying
Party's participation therein at the Indemnified Party's request, and the
Indemnified Party shall reimburse the Indemnifying Party in full for all costs
and expenses of such litigation.  The Indemnifying Party may participate in,
but not control, any defense or settlement controlled by the Indemnified Party
pursuant to this Section 14.3(c), and the Indemnifying Party shall bear its own
costs and expenses with respect to such participation; provided, however, that
if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnifying Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnified Party, then the Indemnifying Party may employ
separate counsel and upon written notification thereof, the Indemnified Party
shall not have the right to assume the defense of such action on behalf of the
Indemnifying Party.

                 (d)      In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification
under this Agreement.  If the Indemnifying Party does not notify the
Indemnified Party within sixty (60) days from its receipt of the Indemnity
Notice that the Indemnifying Party disputes such claim, the claim specified by
the Indemnified Party in the Indemnity Notice shall be deemed a liability of
the Indemnifying Party hereunder.  If the Indemnifying Party has timely
disputed such claim, as provided above, such dispute shall be resolved by
litigation in an appropriate court of competent jurisdiction if the parties do
not reach a settlement of such dispute within thirty (30) days after notice of
a dispute is given.

                 (e)      Payments of all amounts owing by any Indemnifying
Party pursuant to this Article XIV relating to a Third Party Claim shall be
made within thirty (30) days after the latest of (i) the settlement of such
Third Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.  Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice
period or (ii) the expiration of the period for appeal of a final adjudication
of the Indemnifying Party's liability to the Indemnified Party under this
Agreement.

                 (f)      The Indemnifying Party shall provide the Indemnified
Party with written notice of any firm offer that is made to settle or
compromise a Third Party Claim against an Indemnified Party.  If a firm offer
is made to settle such a claim solely by the payment of money damages and the
Indemnifying Party notifies the Indemnified Party in writing that the
Indemnifying Party agrees to such settlement, but the Indemnified Party elects
not to accept and agree to it, the Indemnified Party may continue to contest or
defend such Third Party Claim and, in such event, the total maximum liability
of the Indemnifying Party to indemnify or otherwise reimburse the Indemnified

                 (g)      Notwithstanding any provision herein to the contrary,
the obligation of an Indemnifying Party to provide indemnification to an
Indemnified Party for breach of any representation or warranty as provided in
Sections 14.1(a) or 14.2(a) hereof shall not take effect unless and until the
Damages asserted against or incurred in the aggregate and on a collective basis
by the Indemnified Parties pursuant to either Section 14.1 or 14.2 (as
applicable) as a result of such a breach or breaches exceeds [$100,000].

         Section 14.4     Costs, Expenses and Legal Fees.  Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party

any of the terms of this Agreement.

         Section 14.5     Tax Benefits; Insurance Proceeds.  The total amount
of any indemnity payments owed by one party to another party to this Agreement

correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

                 (a)      at any time prior to the Effective Date by mutual
agreement of all parties;

                 (b)      at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and
delivered by the Company or any Stockholder pursuant to this Agreement is or
becomes untrue or breached in any material respect or if the Company or any

or agreement contained herein, and any such misrepresentation, noncompliance or
breach is not cured, waived or eliminated within thirty (30) days after receipt
of written notice thereof;

                 (c)      at any time prior to the Effective Date by the
Company if any representation or warranty of APP or APP Sub contained in this
Agreement or in any certificate or other document executed and delivered by APP
or APP Sub pursuant to this Agreement is or becomes untrue in any material
respect or if APP fails to comply in any material respect with any covenant or
agreement contained herein, and any such misrepresentation, noncompliance or
breach is not cured, waived or eliminated within thirty (30) days after receipt
of written notice thereof;

                 (d)      at any time prior to the Effective Date by APP if, as
a result of the conduct of due diligence and regulatory compliance procedures,
APP deems termination to be advisable; or

                 (e)      by APP or the Company if the Merger shall not have

                                  ARTICLE XVI

                   Nondisclosure of Confidential Information

         Section 16.1     Non-Disclosure Covenant.  The Company and NewCo
recognize and acknowledge that each has in the past, currently has, and in the
future may possibly have, access to certain Confidential Information of APP and
the Surviving Corporation that is valuable, special and a unique asset of such
entity's business.  APP and APP Sub acknowledge that they had in the past,
currently have, and in the future may possibly have, access to certain
Confidential Information of the Company and NewCo that is valuable, special and
a unique asset of each such business.  The Company, NewCo, APP, and APP Sub,
severally, agree that they will not disclose such Confidential Information to
any person, firm, corporation, association or other entity for any purpose or
reason whatsoever, except (a) to authorized representatives of APP, APP Sub,
Surviving Corporation, NewCo and the Company and (b) to counsel and other
advisers to APP, APP Sub, Surviving Corporation, NewCo and the Company provided
that such advisers (other than counsel) agree to the confidentiality provisions
of this Section 16.1, unless (i) such information becomes available to or known
by the public generally through no fault of the Company, NewCo, APP or APP Sub,
as the case may be, (ii) disclosure is required by law or the order of any
governmental authority under color of law, provided, that prior to disclosing
any information pursuant to this clause (ii) the Company, NewCo, APP or APP
Sub, as the case may be, shall, if possible, give prior written notice thereof
to the Company, NewCo, APP or APP Sub and provide the Company, APP or APP Sub
with the opportunity to contest such disclosure, (iii) the disclosing party
reasonably believes that such disclosure is required in connection with the
defense of a lawsuit against the disclosing party, or (iv) the disclosing party
is the sole and exclusive owner of such Confidential Information as a result of
the Merger or otherwise.  In the event of a breach or threatened breach by the
Company, on the one hand, and APP or APP Sub, on the other hand, of the
provisions of this Section, APP, APP Sub, the Surviving Corporation, NewCo and
the Company shall be entitled to an injunction restraining the other party, as
the case may be, from disclosing, in whole or in part, such Confidential
Information.  Nothing herein shall be construed as prohibiting any of such
parties from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages.

         Section 16.2     Damages.  Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, APP Sub, the Surviving
Corporation, NewCo and the Company agree that, in the event of a breach by
either of them of the foregoing covenant, the covenant may be enforced against
them by injunctions and restraining orders.

         Section 16.3     Survival.  The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                 Miscellaneous

         Section 17.1     Amendment; Waivers.  This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto.  Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto.  The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 17.2     Assignment.  Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any party hereto,
except by APP to a wholly owned subsidiary of APP; provided that any such
assignment shall not relieve APP of its obligations hereunder.

         Section 17.3     Parties in Interest; No Third Party Beneficiaries.
Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the





                                       43
<PAGE>   49
respective heirs, legal representatives, successors and assigns of the parties
hereto.  APP and APP Sub acknowledge and agree that the rights and remedies of
the Company under this Agreement will be directly available to the Stockholders
as third party beneficiaries of the rights and remedies of the Company under
this Agreement, including, without limitation, the rights and remedies under
Article 14 hereof to indemnification from APP and APP Sub against Damages
incurred by the Stockholders resulting from a breach by APP or APP Sub of any
representation, warranty or covenant of APP or APP Sub contained herein.
Except as provided in the preceding sentence or as otherwise provided herein,
neither this Agreement nor any other agreement contemplated hereby shall be
deemed to confer upon any person not a party hereto or thereto any rights or
remedies hereunder or thereunder.

         Section 17.4     Entire Agreement.  This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding
the subject matter hereof, and supersede all prior agreements and
understandings, both written and oral, among the parties, or any of them, with
respect to the subject matter hereof.

         Section 17.5     Severability.  If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 17.6     Survival of Representations, Warranties and
Covenants.  The representations, warranties and covenants contained herein
shall survive the Closing and all statements contained in any certificate,
exhibit or other instrument delivered by or on behalf of the Company, any
Stockholder, APP or APP Sub pursuant to this Agreement shall be deemed to have
been representations and warranties by the Company, such Stockholder, APP and
APP Sub.  Notwithstanding any provision in this Agreement to the contrary, the
representations and warranties contained herein shall survive the Closing until
the second anniversary of the Closing Date except that (a) the representations
and warranties set forth in Section 3.21 with respect to environmental matters
shall survive for a period of ten (10) years, (b) the representations and
warranties set forth in Section 3.30 with respect to tax matters shall survive
until such time as the limitations period has run for all tax periods ended
prior to the Closing Date, (c) the representations and warranties contained in
Section 3.27 and Section 3.33 with respect to healthcare matters shall survive
for a period of six (6) years and (d) solely for purposes of Section 14.1(c)
and Section 14.2(c), and solely to the extent that any party to be indemnified
pursuant to such provisions actually incurs liability under the Securities Act,
the Exchange Act or any other federal or state securities law, the
representations and warranties set forth therein shall survive until the
expiration of any applicable limitations period.

         Section 17.7     Governing Law.  THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF TEXAS.

         Section 17.8     Captions.  The captions in this Agreement are for
convenience of reference only and shall not limit or otherwise affect any of
the terms or provisions hereof.

         Section 17.9     Gender and Number.  When the context requires, the
gender of all words used herein shall include the masculine, feminine and
neuter and the number of all words shall include the singular and plural.

         Section 17.11    Confidentiality; Publicity and Disclosures.  Each
party shall keep this Agreement and its terms confidential, and shall make no
press release or public disclosure, either written or oral, regarding the
transactions contemplated by this Agreement without the prior knowledge and
consent of the other parties hereto; provided that the foregoing shall not
prohibit any disclosure (a) by press release, filing or otherwise that APP has
determined in its good faith judgment and after advice of legal counsel to be
required by federal securities laws or the rules of the National Association of
Securities Dealers, (b) to attorneys, accountants, investment bankers or other
agents of the parties assisting the parties in connection with the transactions
contemplated by this Agreement and (c) by APP in connection with the conduct of
its Initial Public Offering and conducting an examination of the operations and

are not consummated for any reason whatsoever, the parties hereto agree not to
disclose or use any Confidential Information they may have concerning the
affairs of the other parties, except for information that is required by law to
be disclosed; provided that should the transactions contemplated hereby not be
consummated, nothing contained in this Section shall be construed to prohibit
the parties hereto from operating businesses in competition with each other.

         Section 17.12     Notice.  Whenever this Agreement requires or permits
any notice, request, or demand from one party to another, the notice, request

the Company's Common Stock, shall upon surrender of each certificate or
certificates (or completion of appropriate affidavit of lost certificate and
indemnity) receive such allocation of Merger Consideration as determined in
accordance with the provisions of Exhibit B attached hereto; and (ii) until each
certificate or certificates representing Company Common Stock have been
surrendered by the Stockholders, the certificates for Company Common Stock
shall, for all purposes, represent solely the right to receive Merger
Consideration as determined in accordance with the provisions of Exhibit B
attached hereto and Section 2.10 hereof, if applicable. At the Effective Time,
each share of Company Common Stock converted into Merger Consideration shall by
virtue of the Merger and without any action on the part of the holders thereof,

certificates representing Company Common Stock owned by him, her or it, duly
endorsed in blank by the Stockholder, or accompanied by duly executed stock
powers in blank, and with all necessary transfer tax and other revenue stamps,
acquired at the Stockholder's expense, affixed and cancelled. Each Stockholder
agrees to cure any deficiencies with respect to the endorsement of the
certificates or other documents of conveyance with respect to such Company
Common Stock or with respect to the stock powers accompanying any Company Common
Stock. Upon such delivery (or completion of appropriate affidavit of lost
certificate and indemnity), each Stockholder shall receive in exchange therefor
the Merger Consideration pursuant to Exhibit B and Section 2.10 hereof, if
applicable.

lieu thereof reflecting such Stockholder's proportionate interest in a share of
APP Common Stock multiplied by the Initial Public Offering Price.

agreements provided for herein, and the consummation of the transactions

Agreement and any other documents contemplated hereby (with or without the

                                       10
<PAGE>   16
(i) if successful, may, individually or in the aggregate, have a Material
Adverse Effect on the Company or (ii) could adversely affect the ability of the
Company or any Company Subsidiary to effect the transactions contemplated
hereby, and to the knowledge of the Company there is no basis for any such
action or any state of facts or occurrence of any event which would reasonably
be likely to give rise to the foregoing. There are no unsatisfied judgments
against the Company or any Company Subsidiary or any licensed professional or
other individual affiliated with the Company or any Company Subsidiary relating
to services provided on behalf of the Company or any Company Subsidiary or any
consent decrees to which any of the foregoing is subject. Each of the matters,

requirement of any governmental body, agency, authority or court binding on it,

accurate and complete list of all the lease agreements and license agreements to
which the Company or any Company Subsidiary is a party and pursuant to which the
Company or any Company Subsidiary leases (whether as lessor or lessee) or
licenses (whether as licensor or licensee) any real or personal property related
to the operation of its business and which requires payments in excess of
$12,000 per year (the "Lease Agreements"). The Company has delivered to APP true
and complete copies of all of the Lease Agreements. Each Lease Agreement is
valid, effective and in full force in accordance with its terms, and there is
not under any such lease (i) any existing or claimed material default by the
Company or any Company Subsidiary (as applicable) or event of material default
or event which with notice or lapse of time, or both, would constitute a
material default by the Company or any Company Subsidiary (as applicable) and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Company, or, (ii) to the knowledge of the Company, any existing
material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party. To the knowledge of the
Company, there is no pending or threatened reassessment of any property covered
by the Lease Agreements. The Company or any Company Subsidiary will use
reasonable good faith efforts to obtain, prior to the Effective Time, the
consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver to
APP or APP Sub in writing such consents as are necessary to effect a valid and
binding transfer or assignment of the Company's or any Company Subsidiary's
rights thereunder. The Company has a good, clear, valid and enforceable
leasehold interest under each of the Lease Agreements. The Lease Agreements
comply with the exceptions to ownership interests and compensation arrangements
set out in 42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952, and any similar
applicable state law safe harbor or other exemption provisions.

                  (a) Neither the Company nor any Company Subsidiary owns any
interest (other than the Lease Agreements) in real property.

                  (b) The Company and any Company Subsidiary (i) has good title
to all of its properties and assets (real, personal and mixed, tangible and
intangible) and any rights or interests therein which it purports to own
including, without limitation, all the property and assets reflected in the
Company Current Financial Statements; and (ii) owns such rights, interests,
assets and property free and clear of all Encumbrances, title defects or
objections (except for taxes not yet due and payable). The personal property
presently used in connection with the operation of the business of the Company
and the Company Subsidiaries constitutes the necessary personal property assets
to continue operation of the Company and any Company Subsidiary.

         Section 3.16 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, the Company does not have any

way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

         Section 3.17 Contracts and Commitments.

                  (a) The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i) all
agreements between the Company, on the one hand, and any Payor, government
entity, provider, hospital, health maintenance organization, other managed care
organization or other third-party provider, on the other hand, then in effect
relating to the provision of medical, diagnostic imaging or consulting services,
treatments, patient referrals or other similar activities, (ii) all indentures,
mortgages, notes, loan or credit agreements and other agreements and obligations
relating to the borrowing of money or to the direct or indirect guarantee or
assumption of obligations of third parties requiring the Company to make, or
setting forth conditions under which the Company would be required to make,
aggregate future payments in excess of $10,000 in any fiscal year or $25,000 in
the aggregate, (iii) all agreements for capital improvements or acquisitions
involving an amount of $75,000 in any fiscal year or $75,000 in the aggregate,
(iv) all agreements containing a covenant limiting the freedom of the Company
(or any provider employee of the Company) to compete in any line of business
with any person or entity or in any geographic area or (v) all written contracts
and commitments providing for future payments by the Company in excess of
$10,000 in any fiscal year or $25,000 in the aggregate and that are not
cancelable by providing notice of sixty (60) days or less. All such contracts,
agreements or other instruments are in full force and effect, there has been no
threatened cancellation thereof, there are no outstanding disputes thereunder,
each is with unrelated third parties and was entered into on an arms-length
basis and, assuming the receipt of the appropriate consents, all will continue
to be binding in accordance with their terms after consummation of the
transaction contemplated herein; there are no contracts, agreements or other
instruments to which the Company is a party or is bound (other than physician
employment contracts and insurance policies) which could either singularly or in
the aggregate have a Material Adverse Effect on the value to APP or APP Sub of
the assets and properties to be acquired by APP or APP Sub from the Company, or
which could inhibit or prevent the Company from transferring to or vesting in
APP or APP Sub good and sufficient title to the assets and properties to be
acquired by APP or APP Sub and the Surviving Corporation except where the
failure to transfer would not have a Material Adverse Effect on APP or APP Sub.
In every instance where consent is necessary, the Company shall, on or before
the Closing Date, use reasonable good faith efforts to obtain and deliver to APP
or APP Sub in writing, effective as of the Closing Date, such consents as are
necessary to enable the Surviving Corporation to enjoy all of the rights now
enjoyed by the Company under such contracts. Any and all such consents shall be
in a form reasonably acceptable to APP and shall contain an acknowledgment by
the consenting party that the Company has fully complied with and is not in
default under any provision of the particular contract or agreement.
Notwithstanding the foregoing, the Company shall not transfer to APP or APP Sub
any contracts or agreements relating to the provision of professional medical
services or other such agreements and contracts that APP consents to in writing
to be transferred in the Spin-off Transaction. No contract with a health care
provider or Payor has been materially amended or terminated within the last
twelve (12) months.

                  (b) The Company (i) has not received notice of any plan or
intention of any other party to exercise any right to cancel or terminate any
contract, agreement or instrument required to be disclosed pursuant to Section
3.17(a), and to the knowledge of the Company there are no fact(s) that would
justify the exercise of such a right; and (ii) does not currently contemplate,
or have reason to believe any other Person currently contemplates, any amendment
or change to any such contract, agreement or instrument.

December 31, 1997, and (ii) a single line item listing for all private-pay
patients in the aggregate of the Company. The Company has satisfactory relations
with such Payors set forth in (i) above and none of such Payors has notified the

fiscal year ended December 31, 1996, or which is reasonably expected to account
for a dollar volume of purchases paid for by the Company in excess of $25,000

respect thereto (calculated consistent with past practice), of items of a
quality and a quantity usable and saleable in the ordinary course of the
Company's business and conform to generally accepted standards in the industry
of which the Company is a part. The value of the inventories reflected on the
Company Current Balance Sheet contained in the Company Financial Statements are
net of adequate reserves for damaged, excess, and unusable items. Purchase
commitments of the Company for inventory are not materially in excess of normal
requirements, and none of such purchase commitments are at prices in excess of

the Company, there has been no decision not to renew any existing agreement with

business as currently conducted. APP is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, except where such failure to be so qualified
or in good standing would not have a Material Adverse Effect on APP. Copies of
the certificate of incorporation and all amendments thereto of APP and the
bylaws of APP, as amended, and copies of the corporate minutes of APP regarding
the Merger and the transactions contemplated hereby, all of which have been or
will be made available to the Company for review, are true, correct and complete
as in effect on the date of this Agreement and accurately reflect all material
proceedings of the stockholders and directors of APP (and all committees
thereof) regarding the Merger and the transactions contemplated hereby. The
stock record books of APP, which have been or will be made available to the
Company for review, contain true, complete and accurate records of the stock
ownership of APP and the transfer of the shares of its capital stock.

         Section 4.2 Authorization and Validity. APP has all requisite corporate
power to execute and deliver this Agreement and the Other Agreements and to
consummate the Merger and the transactions contemplated hereby. The execution,
delivery and performance by APP of this Agreement and the agreements provided
for herein, including the Other Agreements and the consummation by APP of the
transactions contemplated hereby and thereby are within APP's corporate powers
and have been duly authorized by all necessary action on the part of APP's Board
of Directors. This Agreement has and the Other Agreements have been duly
executed by APP. This Agreement and all other agreements and obligations entered
into and undertaken in connection with the Merger and the transactions
contemplated hereby to which APP is a party constitute, or upon execution will
constitute, valid and binding agreements of APP, enforceable against it in
accordance with their respective terms, except as may be limited by bankruptcy
or other laws affecting creditors' rights generally, or by general equity
principles, or by public policy.

         Section 4.3 Governmental Authorization. Other than complying with the
provisions of the applicable state corporate laws regarding the approval of the
Merger and the filing of the Certificates of Merger and any other required
documents related to the Merger, and other than consents, filings or
notifications required to be made or obtained solely by the Company, the
execution, delivery and performance by APP of this Agreement and the agreements
provided for herein, and the consummation of the Merger and the transactions
contemplated hereby and thereby by APP requires no action by or in respect of,
or filing with, any governmental body, agency, official or authority.

         Section 4.4 Capitalization. The authorized capital stock of APP
consists of [20,000,000] shares of APP Common Stock, of which [2,000,000] shares
are issued and outstanding and [10,000,000] shares of APP Preferred Stock, none
of which are outstanding. Each outstanding share of APP Common Stock has been
legally and validly issued and is fully paid and nonassessable, and was issued
pursuant to a valid exemption from registration under (i) the Securities Act of
1933, as amended, and (ii) all applicable state securities laws. No shares of
capital stock are owned by APP in treasury. No shares of capital stock of APP
have been issued or disposed of in violation of the preemptive rights, rights of
first refusal or similar rights of any stockholders of APP. APP has no bonds,
debentures, notes or other obligations the holders of which have the right to
vote (or are convertible into or exercisable for securities having the right to
vote) with the stockholders of APP on any matter. There exist no options,
warrants, subscriptions, calls, commitments or other rights to purchase, or
securities convertible into or exchangeable for, any of the authorized or
outstanding securities of APP and no option, warrant, subscription, call, or
commitment or commission right of any kind exists which obligates APP to issue
any of its authorized but unissued capital stock. APP has no obligation
(contingent or otherwise) to purchase, redeem or otherwise acquire any of its
equity securities or any interests therein or to pay any dividend or make any
distribution in respect thereof.

         Section 4.5 Subsidiaries and Investments. APP does not own, directly or
indirectly, any capital stock or other equity, ownership or proprietary interest
in any corporation, partnership, association, trust, joint venture or other
entity (the "APP Subsidiaries").

documents contemplated hereby (with or without the giving of notice, the lapse

regulatory body or authority or any other third party except for such consents,

APP; (ii) will not conflict with any provision of APP's certificate of
incorporation or bylaws; (iii) will not conflict with, result in a violation of,

conflict, termination, breach or default, the occurrence of which would not
result in a Material Adverse Effect on APP; and (v) will not create any
Encumbrance or restriction upon APP Common Stock or any of the assets or

any applicable local, state or federal law, ordinance, regulation, order,
injunction or decree, or any other requirement of any governmental body, agency
or authority or court binding on it, or relating to its property or business or

reasonably likely, individually or in the aggregate, to have a Material Adverse
Effect on APP.

<PAGE>   36
specifically for inclusion in the Registration Statements, by exhibit or
otherwise and (ii) in the case of APP or APP Sub, will, at the time the
Registration Statements and each amendment and supplement thereto, if any,
becomes effective under the Securities Act, none of them contain any untrue
statement of a material fact or omit to state any material fact required to be

circumstances under which they were made, not misleading. The Company shall be
entitled to review the Registration Statements and each of the amendments
thereto, if any, prior to the time each becomes effective under the Securities
Act. The Company shall have no responsibility for information contained in the
Registration Statements except for information provided by the Company
specifically for inclusion therein. The Company's review of the Registration
Statements shall not diminish or otherwise affect the representations, covenants
and warranties of APP and APP Sub contained in this Agreement.

concerning itself, its subsidiaries, directors, officers, partners,
Stockholders, and such other matters as may be reasonably requested by APP in

agrees that, with respect to the representations and warranties of such party
contained in this Agreement, such party shall have the continuing obligation
until the Closing to supplement or amend promptly the Disclosure Schedules with
respect to any matter that would have been or would be required to be set forth
or described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on the Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Schedule that constitutes or reflects a Material Adverse Effect on APP may be
made unless the Company consents to such amendment or supplement. For purposes
of this Agreement, including without limitation for purposes of determining
whether the conditions set forth in Sections 10.1 and 11.1 have been fulfilled,
the Disclosure Schedules hereto shall be deemed to be the Disclosure Schedules
as amended or supplemented pursuant to this Section 9.2. In the event that the
Company seeks to amend or supplement a Disclosure Schedule pursuant to this
Section 9.2 and APP does not consent to such amendment or supplement, or APP
seeks to amend or supplement a Disclosure Schedule pursuant to this Section 9.2,
and the Company does not consent, this Agreement shall be deemed terminated by
mutual consent as set forth in Section 15.1(a) hereof.

         Section 9.3 Actions Contrary to Stated Intent. No party hereto will
knowingly, either before or after the Merger, take any action that would prevent
the Merger from qualifying as a tax-free exchange within the meaning of Section
351 of the Code.

         Section 9.4 Public Announcements. The parties hereto will consult with
each other before issuing any press release or making any public statement with
respect to this Agreement and the transactions contemplated hereby and, except

foregoing shall not apply to any disclosure by APP in any filing with the DOJ,
FTC or SEC.

responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by the Company in connection with the Merger shall be paid
by the Company in full immediately prior to the Closing and such expenses shall
be the sole responsibility of the Stockholders following the Closing Date and
not APP.

as a Reorganization and such opinion either is furnished prior to the Effective
Time or is based on facts or events not known at the Effective Time. Each party
shall provide to each other party such tax information, reports, returns, or
schedules as may be reasonably required to assist such party in accounting for
and reporting the Merger as a Reorganization.

         (c) The parties agree that no Stockholder shall be liable for any taxes
incurred by the Company and for which APP has successor liability therefor which
arise solely as a result of the Merger or the consummation of the transactions
contemplated hereby; provided that the foregoing shall not limit or otherwise be
deemed a waiver of any right of indemnification under Section 14.1 for a breach
of any representation, warranty or covenant of the Company or any Stockholder.

         Section 13.3 Current Public Information. APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

                                    Remedies

         Section 14.1 Indemnification by the Company. Subject to the terms and

APP and the Surviving Corporation and their respective directors, officers,
stockholders, employees, agents, attorneys, consultants and Affiliates harmless
from and against all losses, claims, obligations, demands, assessments,
penalties, liabilities, costs, damages, reasonable attorneys' fees and expenses
(including, without limitation, all costs of experts and all costs incidental to
or in connection with any appellate process) (collectively, "Damages") asserted
against or incurred by such individuals and/or entities arising out of or
resulting from:

                  (a) a breach by the Company of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of the Company
contained in this Agreement or in any Schedule or certificate delivered
thereunder;

                  (b) any violation (or alleged violation) by the Company and/or
any of its past or present directors, officers, partners, stockholders,
employees (including, without limitation, any Physician Employee), agents,
attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons in

obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                  (c) any liability under the Securities Act, the Exchange Act
or any other federal or state "blue sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any (i) untrue statement
of a material fact in any Registration Statement or any prospectus forming or
part thereof, or any amendment thereof or supplement thereto relating to the
Company (including any Company Subsidiary) required to be stated therein or (ii)
failure to state information necessary to make the statements therein not
misleading, which untrue statement or failure to state information arises or
results solely from information provided in writing to APP or its counsel by the
Company or any Stockholder or their agents specifically for inclusion in any
such Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto.

         Section 14.2 Indemnification by APP and APP Sub. Subject to the terms
and conditions of this Article XIV, APP and APP Sub jointly and severally hereby
agree to indemnify, defend and hold the Stockholders, the Company and their

consultants and Affiliates harmless from and against all Damages asserted
against or incurred by such individuals and/or entities arising out of or
resulting from:

                  (a) a breach by APP or APP Sub of any representation or
warranty (without giving effect to any Material Adverse Effect qualifier
contained as part of any such representation or warranty) or covenant of APP or
APP Sub contained in this Agreement or in any schedule or certificate delivered
hereunder; and

                  (b) any liability under the Securities Act, the Exchange Act
or any other federal or state "blue sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any untrue statements of
material fact in any Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or required to be
stated therein or failure to state information necessary to make the statements
therein not misleading (except for any liability based upon any actual or
alleged untrue statement of material fact or an omission to state a material
fact relating to the Company or any Stockholder to the extent derived from any
information provided in writing by the Company or a Company Subsidiary or any of
their agents contained in the representations and


                                       37
<PAGE>   43
warranties set forth in this Agreement or any certificate, exhibit, schedule or
instrument required to be delivered under this Agreement.)

                  Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
of any of the parties hereto of liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

         Section 14.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                  (a) Any party claiming indemnification under the Agreement (an
"Indemnified Party") shall promptly (and, in the event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party for whom indemnification is sought (the "Indemnifying
Party) of any third-party claim or claims asserted against the Indemnified Party
("Third Party Claim") that could give rise to a right of indemnification under
this Agreement and (ii) transmit to the Indemnifying Party a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of Damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement. The failure to promptly deliver a Claim Notice shall not relieve any
Indemnifying Party of its obligations to any Indemnified Party with respect to
the related Third Party Claim except to the extent that the resulting delay is
materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (x) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article XIV
with respect to such Third Party Claim and (y) whether the Indemnifying Party
desires, at the sole cost and expense of such Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

                  (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may employ separate counsel at the expense of the Indemnifying Party, and
upon written notification thereof, the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of the Indemnified Party;
provided further that the Indemnifying Party shall not, in connection with any
one such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in


                                       38
<PAGE>   44
writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                  (c) If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to it that are different from or additional
to those available to the Indemnified Party, then the Indemnifying Party may
employ separate counsel and upon written notification thereof, the Indemnified
Party shall not have the right to assume the defense of such action on behalf of
the Indemnifying Party.

                  (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                  (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period for appeal of a final adjudication of the
Indemnifying Party's liability to the Indemnified Party under this Agreement.

                  (f) The Indemnifying Party shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such


                                       39
<PAGE>   45
settlement, but the Indemnified Party elects not to accept and agree to it, the
Indemnified Party may continue to contest or defend such Third Party Claim and,
in such event, the total maximum liability of the Indemnifying Party to
indemnify or otherwise reimburse the Indemnified Party hereunder with respect to
such a claim shall be limited to and shall not exceed the amount of such
settlement offer, plus reasonable out-of-pocket costs and reasonable expenses
(including reasonable attorneys' fees and disbursements) to the date of notice
that the Indemnifying Party desired to accept such settlement.

                  (g) Notwithstanding any provision herein to the contrary, the
obligation of an Indemnifying Party to provide indemnification to an Indemnified
Party for breach of any representation or warranty as provided in Sections
14.1(a) or 14.2(a) hereof shall not take effect unless and until the Damages
asserted against or incurred in the aggregate and on a collective basis by the
Indemnified Parties pursuant to either Section 14.1 or 14.2 (as applicable) as a
result of such a breach or breaches exceeds
[$____________].

         Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.

                                   ARTICLE XV

                                   Termination

         Section 15.1 Termination. This Agreement may be terminated and the
Merger and the Acquisitions may be abandoned:

                  (a) at any time prior to the Effective Date by mutual
agreement of all parties;

                  (b) at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and delivered
by the Company or any Stockholder pursuant to this Agreement is or becomes
untrue or breached in any material respect or if the Company or any Stockholder
fails to comply in any material respect with any material covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

                  (c) at any time prior to the Effective Date by the Company if
any representation or warranty of APP or APP Sub contained in this Agreement or
in any certificate or other document executed and delivered by APP or APP Sub
pursuant to this Agreement is or becomes untrue in any material respect or if
APP fails to comply in any material respect with any covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

                  (d) at any time prior to the Effective Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures, APP
deems termination to be advisable; or

                  (e) by APP or the Company if the Merger shall not have been
consummated by September 30, 1997.

         Section 15.2 Effect of Termination. Except as set forth in Section
16.3, in the event this Agreement is terminated pursuant to this Article XV,
this Agreement shall forthwith become void.

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

         Section 16.1 Non-Disclosure Covenant. The Company recognizes and
acknowledges that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP and the
Surviving Corporation that is valuable, special and a unique asset of such
entity's business. APP and APP Sub acknowledge that they had in the past,
currently have, and in the future may possibly have, access to certain
Confidential Information of the Company that is valuable, special and a unique
asset of each such business. The Company, APP, and APP Sub, severally, agree
that they will not disclose such Confidential Information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except (a) to authorized representatives of APP, APP Sub, Surviving Corporation
and the Company and (b) to counsel and other advisers to APP, APP Sub, Surviving
Corporation and the Company provided that such advisers (other than counsel)
agree to the confidentiality provisions of this Section 16.1, unless (i) such
information becomes available to or known by the public generally through no
fault of the Company, APP or APP Sub, as the case may be, (ii) disclosure is
required by law or the order of any governmental authority under color of law,
provided, that prior to disclosing any information pursuant to this clause (ii)
the Company, APP or APP Sub, as the case may be, shall, if possible, give prior
written notice thereof to the Company, APP or APP Sub and provide the Company,
APP or APP Sub with the opportunity to contest such disclosure, (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, or (iv)
the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Merger or otherwise. In the event of a breach or
threatened breach by the Company, on the one hand, and APP or APP Sub, on the
other hand, of the provisions of this Section, APP, APP Sub, the Surviving
Corporation and the Company shall be entitled to an injunction restraining the
other party, as the case may be, from disclosing, in whole or in part, such
Confidential Information. Nothing herein shall be construed as prohibiting any
of such parties from pursuing any other available remedy for such breach or
threatened breach, including the recovery of damages.

         Section 16.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, APP Sub, the Surviving Corporation and the
Company agree that, in the event of a breach by either of them of the foregoing
covenant, the covenant may be enforced against them by injunctions and
restraining orders.

         Section 16.3 Survival. The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                  Miscellaneous

         Section 17.1 Amendment; Waivers. This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto. Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto. The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 17.2 Assignment. Neither this Agreement nor any right created
hereby or in any agreement entered into in connection with the transactions
contemplated hereby shall be assignable by any party hereto, except by APP to a
wholly owned subsidiary of APP; provided that any such assignment shall not
relieve APP of its obligations hereunder.

         Section 17.3 Parties in Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. APP and APP Sub
acknowledge and agree that the rights and remedies of the Company under this
Agreement will be directly available to the Stockholders as third party
beneficiaries of the rights and remedies of the Company under this Agreement,
including, without limitation, the rights and remedies under Article 14 hereof
to indemnification from APP and APP Sub against Damages incurred by the
Stockholders resulting from a breach by APP or APP Sub of any representation,
warranty or covenant of APP or APP Sub contained herein. Except as provided in
the preceding sentence or as otherwise provided herein, neither this Agreement
nor any other agreement contemplated hereby shall be deemed to confer upon any
person not a party hereto or thereto any rights or remedies hereunder or
thereunder.

         Section 17.4 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

         Section 17.5 Severability. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 17.6 Survival of Representations, Warranties and Covenants. The
representations, warranties and covenants contained herein shall survive the
Closing and all statements contained in any certificate, exhibit or other
instrument delivered by or on behalf of the Company, any Stockholder, APP or APP
Sub pursuant to this Agreement shall be deemed to have been representations and
warranties by the Company, such Stockholder, APP and APP Sub. Notwithstanding
any provision in this Agreement to the contrary, the representations and
warranties contained herein shall survive the Closing until the second
anniversary of the Closing Date except that (a) the representations and
warranties set forth in Section 3.21 with respect to environmental matters shall
survive for a period of ten (10) years, (b) the representations and warranties
set forth in Section 3.30 with respect to tax matters shall survive until such
time as the limitations period has run for all tax periods ended prior to the
Closing Date, (c) the representations and warranties contained in Section 3.27
and Section 3.33 with respect to healthcare matters shall survive for a period
of six (6) years and (d) solely for purposes of Section 14.1(c) and Section
14.2(c), and solely to the extent that any party to be indemnified pursuant to
such provisions actually incurs liability under the Securities Act, the Exchange
Act or any other federal or state securities law, the representations and
warranties set forth therein shall survive until the expiration of any
applicable limitations period.

         Section 17.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF CALIFORNIA.

         Section 17.8 Captions. The captions in this Agreement are for
convenience of reference only and shall not limit or otherwise affect any of the
terms or provisions hereof.

         Section 17.9 Gender and Number. When the context requires, the gender
of all words used herein shall include the masculine, feminine and neuter and
the number of all words shall include the singular and plural.

         Section 17.11 Confidentiality; Publicity and Disclosures. Each party
shall keep this Agreement and its terms confidential, and shall make no press
release or public disclosure, either written or oral, regarding the transactions
contemplated by this Agreement without the prior knowledge and consent of the
other parties hereto; provided that the foregoing shall not prohibit any
disclosure (a) by press release, filing or otherwise that APP has determined in
its good faith judgment and after advice of legal counsel to be required by

disclose or use any Confidential Information they may have concerning the
affairs of the other parties, except for information that is required by law to

the knowledge of the Company there is no basis for any such action or any state
of facts or occurrence of any event which would reasonably be likely to give
rise to the foregoing. There are no unsatisfied judgments against the Company or
any Company Subsidiary or any licensed professional or other individual
affiliated with the Company or any Company Subsidiary relating to services
provided on behalf of the Company or any Company Subsidiary or any consent
decrees to which any of the foregoing is subject. Each of the matters, if any,
set forth in this Section 3.12 is fully covered by policies of insurance of the
Company or any Company Subsidiary as in effect on the date hereof.

         Section 3.13 No Violation of Law. Neither the Company nor any Company
Subsidiary has been, nor shall be as of the Effective Time (by virtue of any
action, omission to act, contract to which it is a party or any occurrence or
state of facts whatsoever), in violation of any applicable local, state or
federal law, ordinance, regulation, order, injunction or decree, or any other
requirement of any governmental body, agency, authority or court binding on it,
or relating to its properties, assets or business or its advertising, sales or
pricing practices, except for violations which, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
the Company.

         Section 3.14 Lease Agreements. The Disclosure Schedules contain a true,
accurate and complete list of all the lease agreements and license agreements to
which the Company or any Company Subsidiary is a party and pursuant to which the
Company or any Company Subsidiary leases (whether as lessor or lessee) or
licenses (whether as licensor or licensee) any real or personal property related
to the operation of its business and which requires payments in excess of
$12,000 per year (the "Lease Agreements"). The Company has delivered to APP true
and complete copies of all of the Lease Agreements. Each Lease Agreement is
valid, effective and in full force in accordance with its terms, and there is
not under any such lease (i) any existing or claimed material default by the
Company or any Company Subsidiary (as applicable) or event of material default
or event which with notice or lapse of time, or both, would constitute a
material default by the Company or any Company Subsidiary (as applicable) and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Company, or, (ii) to the knowledge of the Company, any existing
material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party. To the knowledge of the
Company, there is no pending or threatened reassessment of any property covered
by the Lease Agreements. The Company or any Company Subsidiary will use
reasonable good faith efforts to obtain, prior to the Effective Time, the
consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver to
APP or APP Sub in writing such consents as are necessary to effect a valid and
binding transfer or assignment of the Company's or any Company Subsidiary's
rights thereunder. The Company has a good, clear, valid and enforceable
leasehold interest under each of the Lease Agreements. The Lease Agreements
comply with the exceptions to ownership interests and compensation arrangements
set out in 42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952, and any similar
applicable state law safe harbor or other exemption provisions.

                  (a) Neither the Company nor any Company Subsidiary owns any
interest (other than the Lease Agreements) in real property.

                  (b) The Company and any Company Subsidiary (i) has good title
to all of its properties and assets (real, personal and mixed, tangible and
intangible) and any rights or interests therein which it purports to own
including, without limitation, all the property and assets reflected in the
Company Current Financial Statements; and (ii) owns such rights, interests,
assets and property free and clear of all Encumbrances, title defects or
objections (except for taxes not yet due and payable). The personal property
presently used in connection with the operation of the business of the Company
and the Company Subsidiaries constitutes the necessary personal property assets
to continue operation of the Company and any Company Subsidiary.

         Section 3.16 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, the Company does not have any
direct or indirect indebtedness for borrowed money, including indebtedness by
way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

         Section 3.17 Contracts and Commitments.

                  (a) The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health
maintenance organization, other managed care organization or other third-party
provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of

conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000 in

providing notice of sixty (60) days or less. All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is with
unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP or APP Sub of the
assets and properties to be acquired by APP or APP Sub from the Company, or
which could inhibit or prevent the Company from transferring to or vesting in
APP or APP Sub good and sufficient title to the assets and properties to be
acquired by APP or APP Sub and the Surviving Corporation except where the
failure to transfer would not have a Material Adverse Effect on APP or APP Sub.
In every instance where consent is necessary, the Company shall, on or before
the Closing Date, use reasonable good faith efforts to obtain and deliver to APP
or APP Sub in writing, effective as of the Closing Date, such consents as are
necessary to enable the Surviving Corporation to enjoy all of the rights now
enjoyed by the Company under such contracts. Any and all such consents


                                       12
<PAGE>   18
shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. Notwithstanding the foregoing, the Company shall not transfer to APP
or APP Sub any contracts or agreements relating to the provision of professional
medical services or other such agreements and contracts that APP consents to in
writing to be transferred to NewCo in the Spin-off Transaction. No contract with
a health care provider or Payor has been materially amended or terminated within
the last twelve (12) months.

                  (b) The Company (i) has not received notice of any plan or
intention of any other party to exercise any right to cancel or terminate any
contract, agreement or instrument required to be disclosed pursuant to Section
3.17(a), and to the knowledge of the Company there are no fact(s) that would
justify the exercise of such a right; and (ii) does not currently contemplate,
or have reason to believe any other Person currently contemplates, any amendment
or change to any such contract, agreement or instrument.

         Section 3.18 Employee Matters. The Company is not currently a party to
any employment contract (except for oral employment agreements which are

regulations from time to time promulgated thereunder ("ERISA")), profit sharing,
bonus, stock option, stock purchase or other nonqualified benefit or
compensation commitments, benefit plans, arrangements or plans (whether written
or oral), including all welfare plans (as defined in Section 3(1) of ERISA) of
or pertaining to the Company and any of its present or former employees, or any
predecessors in interest. As of April 30, 1997, the Company employed a
collective total of 32 part-time and 58 full-time employees and 10 per diem

Company is not delinquent in payment to any of its employees or Physician
Employees for wages, salaries, bonuses or other direct compensation for any
services performed for it to the date hereof or amounts required to be

Employment Opportunity Commission or any federal, state or local agency or court
against the Company. There have been no governmental audits of the equal
employment opportunity practices of the Company and, to the knowledge of the
Company, no basis for any such audit exists which, if conducted would result in
a Material Adverse Effect on the Company;

                  (b) Administration. Each Employee Benefit Plan has been

any Employee Benefit Plan is currently the subject of an audit, investigation,
enforcement action or other similar proceeding conducted by any state or federal

Employee Benefit Plan subject to Title IV of ERISA, the assets of each such plan
are at least equal in value to the present value of accrued benefits determined
on an ongoing basis as of the date hereof. With respect to each Employee Benefit
Plan described in Section 501(c)(9) of the Code, the assets of each such plan
are at least equal in value to the present value of accrued benefits, based upon
the most recent actuarial valuation as of a date no more than ninety (90) days

that would result in the imposition of liability against APP, APP Sub or any of
its Affiliates by the Pension Benefit Guaranty Corporation ("PBGC") as a result
of any act or omission by the Company or any member of a Controlled Group. No
reportable event (within the meaning of Section 4043 of ERISA) for which the

                  (l) Other Compensation Arrangements. Neither the Company nor,
to the Company's knowledge, any Stockholder or Physician Employee is a party to
any compensation or debt arrangement with any Person relating to the provision

         Section 3.21 Environmental Matters.

                  (a) Neither the Company nor any Company Subsidiary has, within

Environmental Law that had, or would


                                       15
<PAGE>   21
reasonably be likely to have, a Material Adverse Effect on the Company. Neither
the Company nor any Company Subsidiary has engaged in any activity or failed to
undertake any activity which action or failure to act has given, or would
reasonably be likely to give, rise to any Environmental Liabilities or
enforcement action by any federal, state or local regulatory agency or
authority, or has resulted, or would reasonably be likely to result, in any fine
or penalty imposed pursuant to any Environmental Law. The Disclosure Schedules

                  "Regulated Activity" shall mean any generation, treatment,

         Section 3.23 Insurance Policies. The Disclosure Schedules list and
briefly describe the Company's policies of insurance to which the Company or any
Company Subsidiary is a party or under which the Company or any Company
Subsidiary, officer or director thereof is or has been covered at any time

                                       16
<PAGE>   22

equitable remedies and all premiums with respect thereto which are due and
payable are currently paid. All Insurance Policies currently maintained by the
Company or any Company Subsidiary ("Current Policies") taken together, (i)

without interruption up to and including the Closing Date. True, complete and
correct copies of all Insurance Policies have been provided to APP. Neither the
Company nor any Company Subsidiary nor any officer or director thereof has
received any notice or other written communication from any issuer of any
Current Policy cancelling such policy, materially increasing any deductibles or
retained amounts thereunder, or materially increasing the annual or other
premiums payable thereunder and, to the knowledge of the Company, no such
cancellation or increase of deductibles, retainages or premiums is threatened.
There are no outstanding claims, settlements or premiums owed against any
Insurance Policy, and all required notices have been given and all known
potential or actual claims under any Insurance Policy have been presented in due

professional liability insurance coverage which has been denied by an insurance
agency or carrier. The Disclosure Schedules also set forth a list of all claims
under any Insurance Policy in excess of $10,000 per occurrence filed by the
Company or any Company Subsidiary during the immediately preceding three-year
period. Each Physician Employee has, at all times while a Physician Employee,

bad debts and, are, to the extent still uncollected, to the knowledge of the
Company collectible in the ordinary course of business, net of reserves for
doubtful and uncollectible accounts shown in the Company Financial Statements or

December 31, 1997, and (ii) a single line item listing for all private-pay
patients in the aggregate of the Company. The Company has satisfactory relations
with such Payors set forth in (i) above and none of such Payors has notified the

deny any payments due from, or any claims for payment submitted to any such
party.

         Section 3.25 Accounts Payable; Suppliers.

                  (a) The Disclosure Schedules set forth a true and complete (i)
list of the accounts payable of the Company as of March 31, 1997, and (ii) list

fiscal year ended December 31, 1996, or which is reasonably expected to account
for a dollar volume of purchases paid for by the Company in excess of $25,000

Balance Sheet contained in the Company Financial Statements consisted, and all
such items on hand on the date of this Agreement consist, and all such items on
hand at the Effective Time will consist, net of all applicable reserves with
respect thereto (calculated consistent with past practice), of items of a
quality and a quantity usable and saleable in the ordinary course of the
Company's business and conform to generally accepted standards in the industry

         Section 3.27 Licenses, Authorization and Provider Programs.

licensed employee or independent contractor of the Company (i) is the holder of
all valid licenses, approvals, orders, consents, permits, registrations,
qualifications and other rights and authorizations required by law, ordinance,
regulation or ruling of any governmental regulatory authority necessary to
operate its business or his or her specialty and (ii) is eligible to participate
in and to receive reimbursement under Titles XVIII and XIX of the Social
Security Act (the "Medicare and Medicaid Programs") and any other programs
funded in whole or in part by federal, state or local entities for which the
Company is eligible ("Governmental Programs"). The Company, the Stockholders,
and each Physician Employee has a current provider number for such Governmental
Programs and with such private non-governmental programs (including without
limitation any private insurance program) under which the Company is presently
receiving payments directly or indirectly from any Payor for patient care
provided by such Physician Employee, licensed employee or independent contractor
(such non-governmental programs herein referred to as "Private Programs"). A

authorizations (including, but not limited to verification of Medicare and
Medicaid provider numbers and participating physician contracts under 1842(h) of
the Social Security Act), and provider agreements, is set forth in the
Disclosure Schedules, true, complete and correct copies of which have been
provided to APP. No violation, default, order or deficiency exists with respect
to any of the items listed in the Disclosure Schedules except for such
violations, defaults, orders or deficiencies which would not be reasonably
likely to have a Material Adverse Effect on the Company, and there is no action
pending or to the Company's knowledge recommended by any state or federal
agencies having jurisdiction over the items listed in the Disclosure Schedules,
either to revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program, and
no event has occurred which, with or without notice or lapse of time, or both,
would constitute grounds for a violation, order or deficiency with respect to
any of the items listed in the Disclosure Schedules to revoke, withdraw or
suspend any material license to operate its business as is presently being
conducted by it. To the knowledge of the Company, there has been no decision not
to renew any existing agreement with any provider or Payor relating to the
Company's business as presently being conducted by it. Neither the Company nor
any Physician Employee (i) has had his/her/its professional license, Drug
Enforcement Agency number, Medicare/Medicaid provider status or staff privileges
at any hospital or diagnostic imaging center suspended, relinquished, terminated
or revoked (including orders that have been entered by any such entities but
stayed), (ii) has been reprimanded in writing, sentenced, or disciplined by any
licensing board, state agency, regulatory body or authority, hospital, Payor or
specialty board (including orders that have been entered by any such entities
but stayed), or (iii) is the subject of an initial or final determination by any
federal or state authority that could result in any demand or reimbursement
under the Medicare, Medicaid or Government Programs or any exclusion or which
monetary penalty under federal or state law or (iv) has had a final judgment or
settlement entered against him/her/it in connection with a malpractice or
similar action.

                  (b) The Company is not required, or for the 72-month period
prior to the Effective Time was not required, to file any cost reports or other
reports with any Governmental Program or Private Program.

APP, as amended, and copies of the corporate minutes of APP regarding the Merger

available to the Company for review, are true, correct and complete as in effect

correct on the Closing Date as if made on that date:

         Section 5.1 Organization and Good Standing; Qualification. NewCo is a
professional corporation duly organized, validly existing and in good standing
under the laws of its state of organization, with all requisite corporate power
and authority to carry on the business in which it intends to engage, to own the

the Security Agreement and the Physician Employment Agreements and consummate
the transactions and perform the services contemplated thereby. NewCo is duly
qualified and licensed to do business and is in good standing in all
jurisdictions where the nature of its intended business makes such qualification
necessary, which jurisdictions are listed in the Disclosure Schedules, except
where the failure to be so qualified shall not have a Material Adverse Effect on
NewCo.

         Section 5.2 Capitalization. The authorized capital stock of NewCo
consists of [_____] shares of NewCo Common Stock, of which [______] shares are
issued and outstanding, and no shares of capital stock of NewCo are held in

Common Stock, free and clear of any Encumbrance. Each outstanding share of NewCo
Common


                                       25
<PAGE>   31
Stock has been legally and validly issued and is fully paid and nonassessable.
There exist no options, warrants, subscriptions or other rights to purchase, or
securities convertible into or exchangeable for, any of the authorized or
outstanding securities of NewCo. No shares of capital stock of NewCo have been
issued or disposed of in violation of the preemptive rights, rights of first
refusal or similar rights of any of NewCo's stockholders.

         Section 5.3 Corporate Records. The copies of the articles or
certificate of incorporation and bylaws, and all amendments thereto, of NewCo
that have been delivered or made available to APP are true, correct and complete
copies thereof, as in effect on the Closing Date.

         Section 5.4 Authorization and Validity. The execution, delivery and
performance by NewCo of the Service Agreement, the Security Agreement, the
Physician Employment Agreements and the other agreements contemplated thereby,
and the consummation of the transactions and provision of services contemplated
thereby, have been duly authorized by the Board of Directors of NewCo. The
Service Agreement, the Security Agreement, the Physician Employment Agreements
and each other agreement contemplated thereby will be as of the Closing Date
duly executed and delivered by NewCo and will constitute valid and binding
obligations of NewCo enforceable against NewCo in accordance with their
respective terms, except as may be limited by applicable bankruptcy, or other
laws affecting creditors' rights generally, or by general equity principles, or
by public policy.

         Section 5.5 No Violation. Neither the execution, delivery or
performance of the Service Agreement, the Security Agreement, the Physician
Employment Agreements or the other agreements contemplated thereby nor the
consummation of the transactions or provision of services contemplated thereby
will (a) conflict with, or result in a violation or breach of the terms,
conditions or provisions of, or constitute a default under, the articles or
certificate of incorporation or bylaws of NewCo, or (b) violate or conflict with
any applicable local, state or federal law, ordinance, regulation, order,
injunction or decree, or any other requirement of any governmental body, agency
or authority or court binding on it, or relating to its property or business.

         Section 5.6 No Business, Agreements, Assets or Liabilities. NewCo has
not commenced business since its incorporation. Other than its articles or
certificate of incorporation and bylaws, and as of the Closing Date, the Service
Agreement, the Security Agreement, the Physician Employment Agreements, and the
other contracts and agreements assigned to NewCo as part of the Spin-Off
Transaction, NewCo is not a party to or subject to any agreement, indenture or
other instrument. NewCo does not own any assets (tangible or intangible) other
than the consideration received upon the issuance of shares of its capital stock
or pursuant to the Spin-Off Transaction, and NewCo does not have any
liabilities, accrued, contingent or otherwise (known or unknown and asserted or
unasserted) other than those assumed pursuant to the Spin-Off Transaction.

         Section 5.7 Compliance with Laws. NewCo has complied with all
applicable laws, regulations and licensing requirements and has filed with the
proper authorities all necessary statements and reports, except where failure to
so comply or file would not, individually or in the aggregate, have a Material
Adverse Effect on NewCo.

efforts to obtain the unanimous approval of its Stockholders to the Merger. In

such agreements.

         Section 7.10 Funding of Accrued Employee Benefits. The Company hereby
covenants and agrees that it will take whatever steps are necessary to pay for
or fund completely any accrued benefits, where applicable, or vested accrued
benefits for which the Company or any entity might have any liability whatsoever
arising from any tax-qualified plan as required under applicable law. The
Company acknowledges that the purpose and intent of this covenant is to assure
that APP Sub shall have no liability whatsoever at any time after the Closing
Date with respect to any such tax-qualified plan, unless such plan is merged
with a plan sponsored by APP or APP Sub.

         Section 7.11 Accounting and Tax Matters. The Company will not change in
any material respect the accounting methods or practices followed by the Company
(including any material change in any assumption underlying, or any method of

accounting method except in the ordinary course of business consistent with past
practice, change any tax accounting method, enter into any closing agreement,
settle any tax claim or assessment or consent to any tax claim or assessment or
any waiver of the statute of limitations for any such claim or assessment. The

taxes of the Company required to be filed by it, and pay all taxes required to
be paid by it, on or before the Closing Date.

         Section 7.12 Spin-Off Transaction. The Company shall form, organize and
incorporate NewCo in the state of California, and the articles or certificate of
incorporation and bylaws of NewCo shall be in form and substance reasonably
satisfactory to APP. Except for consummating the Spin-Off Transaction, NewCo

instruments necessary pursuant to and in compliance with applicable law to
effect the Spin-Off Transaction, including without limitation, the following:
Prior to the Closing, the Company shall transfer to NewCo good, valid and

Employee Benefit Plans, all contracts and agreements and other assets listed on
the Disclosure Schedules (to be delivered by the Company prior to Closing, which
schedule will be subject to the approval of APP, which approval shall not be
unreasonably withheld) which by law either cannot be acquired or cannot be used
by APP because they relate to the practice of medicine or radiology, and shall
contribute to NewCo such other consideration and assets of the Company as may be
required under applicable law, in exchange for the issuance by NewCo of shares
of NewCo Common Stock, such shares being all of the issued and outstanding
shares of NewCo Common Stock. The Company shall then distribute the shares of
NewCo Common Stock to the Stockholders in proportion to their respective
ownership interest in the Company.

representations, warranties, covenants or agreements of APP under this
Agreement.

Qualified Plan shall be conditioned on a favorable determination letter from the
IRS. Costs associated with the establishment and design of the

thereof, the "Registration Statements"). APP shall obtain all necessary state
securities law or "Blue Sky" permits and approvals required to carry out the
transactions contemplated by this Agreement. The Company shall cooperate with
APP in the preparation of the Registration Statements and shall furnish all
information concerning the Company and NewCo as may be reasonably requested in
connection with any such action in a timely manner.

         (b) The Company, APP and APP Sub and each separately represent and
warrant that (i) in the case of the Company, none of the written information or
documents supplied or to be supplied by it specifically for inclusion in the
Registration Statements, by exhibit or otherwise and (ii) in the case of APP or
APP Sub, will, at the time the Registration Statements and each amendment and
supplement thereto, if any, becomes effective under the Securities Act, none of
them contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. The Company shall be entitled to review the Registration Statements
and each of the amendments thereto, if any, prior to the time each becomes
effective under the Securities Act. The Company shall have no responsibility for
information contained in the Registration Statements except for information
provided by the Company specifically for inclusion therein. The Company's review
of the Registration Statements shall not diminish or otherwise affect the
representations, covenants and warranties of APP and APP Sub contained in this
Agreement.

         (c) The Company shall, upon request, furnish APP with all information
concerning itself, its subsidiaries, directors, officers, partners, Stockholders

until the Closing to supplement or amend promptly the Disclosure Schedules with
respect to any matter that would have been or would be required to be set forth
or described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Schedule that constitutes or reflects a
Material Adverse Effect on the Company may be made unless APP consents to such
amendment or supplement, and no amendment or supplement to a Disclosure Schedule
that constitutes or reflects a Material Adverse Effect on APP may be made unless
the Company consents to such amendment or supplement. For purposes of this
Agreement, including without limitation for purposes of determining whether the
conditions set forth in Sections 10.1 and 11.1 have been fulfilled, the
Disclosure Schedules hereto shall be deemed to be the Disclosure Schedules as
amended or supplemented pursuant to this Section 9.2. In the event that the
Company seeks to amend or supplement a Disclosure Schedule pursuant to this
Section 9.2 and APP does not consent to such amendment or supplement, or APP
seeks to amend

make any such public statement prior to such consultation, although the
foregoing shall not apply to any disclosure by APP in any filing with the DOJ,
FTC or SEC.

         Section 9.5 Expenses. Each party to this Agreement shall be solely
responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by

received by a Stockholder in the Merger (a "Reorganization").

as a Reorganization and such opinion either is furnished prior to the Effective

145(d) under the Securities Act.

obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                  (c) any liability under the Securities Act, the Exchange Act

thereof, or any amendment thereof or supplement thereto relating to the Company
(including any Company Subsidiary) or NewCo required to be stated therein or
(ii) failure to state information necessary to make the statements therein not

Company or any Stockholder or their agents specifically for inclusion in any
such Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto.

provided in writing by the Company or a Company Subsidiary or any of their
agents contained in the representations and warranties set forth in this
Agreement or any certificate, exhibit, schedule or instrument required to be
delivered under this Agreement.)

                  Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
of any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

         Section 14.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                  (a) Any party claiming indemnification under the Agreement (an
"Indemnified Party") shall promptly (and, in the event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party for whom indemnification is sought (the "Indemnifying
Party) of any third-party claim or claims asserted against the Indemnified Party
("Third Party Claim") that could give rise to a right of indemnification under
this Agreement and (ii) transmit to the Indemnifying Party a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the

<PAGE>   45
amount of Damages attributable to the Third Party Claim and the basis of the
Indemnified Party's request for indemnification under this Agreement. The
failure to promptly deliver a Claim Notice shall not relieve any Indemnifying
Party of its obligations to any Indemnified Party with respect to the related
Third Party Claim except to the extent that the resulting delay is materially
prejudicial to the defense of such claim. Within thirty (30) days after receipt
of any Claim Notice (the "Election Period"), the Indemnifying Party shall notify
the Indemnified Party (x) whether the Indemnifying Party disputes its potential
liability to the Indemnified Party under this Article XIV with respect to such
Third Party Claim and (y) whether the Indemnifying Party desires, at the sole
cost and expense of such Indemnifying Party, to defend the Indemnified Party
against such Third Party Claim.

                  (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may employ separate counsel at the expense of the Indemnifying Party, and
upon written notification thereof, the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of the Indemnified Party;
provided further that the Indemnifying Party shall not, in connection with any
one such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                  (c) If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense


                                       40
<PAGE>   46
pursuant to this Section or of the Indemnifying Party's participation therein at
the Indemnified Party's request, and the Indemnified Party shall reimburse the
Indemnifying Party in full for all costs and expenses of such litigation. The
Indemnifying Party may participate in, but not control, any defense or
settlement controlled by the Indemnified Party pursuant to this Section 14.3(c),
and the Indemnifying Party shall bear its own costs and expenses with respect to
such participation; provided, however, that if the named parties to any such
action (including any impleaded parties) include both the Indemnifying Party and
the Indemnified Party, and the Indemnifying Party has been advised by counsel
that there may be one or more legal defenses available to it that are different
from or additional to those available to the Indemnified Party, then the
Indemnifying Party may employ separate counsel and upon written notification
thereof, the Indemnified Party shall not have the right to assume the defense of
such action on behalf of the Indemnifying Party.

                  (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                  (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period for appeal of a final adjudication of the
Indemnifying Party's liability to the Indemnified Party under this Agreement.

                  (f) The Indemnifying Party shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Party to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Party desired to accept such settlement.

                  (g) Notwithstanding any provision herein to the contrary, the
obligation of an Indemnifying Party to provide indemnification to an Indemnified
Party for breach of any representation or warranty as provided in Sections
14.1(a) or 14.2(a) hereof shall not take effect unless and until the Damages
asserted against or incurred in the aggregate and on a collective basis by the
Indemnified Parties pursuant to either Section 14.1 or 14.2 (as applicable) as a
result of such a breach or breaches exceeds $100,000.

         Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'


                                       41
<PAGE>   47
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.


                                   ARTICLE XV

                                   Termination

         Section 15.1 Termination. This Agreement may be terminated and the
Merger and the Acquisitions may be abandoned:

                  (a) at any time prior to the Effective Date by mutual
agreement of all parties;

                  (b) at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and delivered
by the Company or any Stockholder pursuant to this Agreement is or becomes
untrue or breached in any material respect or if the Company or any Stockholder
fails to comply in any material respect with any material covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

                  (c) at any time prior to the Effective Date by the Company if
any representation or warranty of APP or APP Sub contained in this Agreement or
in any certificate or other document executed and delivered by APP or APP Sub
pursuant to this Agreement is or becomes untrue in any material respect or if
APP fails to comply in any material respect with any covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

                  (d) at any time prior to the Effective Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures, APP
deems termination to be advisable; or

                  (e) by APP or the Company if the Merger shall not have been
consummated by September 30, 1997.

         Section 15.2 Effect of Termination. Except as set forth in Section
16.3, in the event this Agreement is terminated pursuant to this Article XV,
this Agreement shall forthwith become void.

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

         Section 16.1 Non-Disclosure Covenant. The Company and NewCo recognize
and acknowledge that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP and the
Surviving Corporation that is valuable, special and a unique asset of such
entity's business. APP and APP Sub acknowledge that they had in the past,
currently have, and in the future may possibly have, access to certain
Confidential Information of the Company and NewCo that is valuable, special and
a unique asset of each such business. The Company, NewCo, APP, and APP Sub,
severally, agree that they will not disclose such Confidential Information to
any person, firm, corporation, association or other entity for any purpose or
reason whatsoever, except (a) to authorized representatives of APP, APP Sub,
Surviving Corporation, NewCo and the Company and (b) to counsel


                                       42
<PAGE>   48
and other advisers to APP, APP Sub, Surviving Corporation, NewCo and the Company
provided that such advisers (other than counsel) agree to the confidentiality
provisions of this Section 16.1, unless (i) such information becomes available
to or known by the public generally through no fault of the Company, NewCo, APP
or APP Sub, as the case may be, (ii) disclosure is required by law or the order
of any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii) the Company, NewCo, APP
or APP Sub, as the case may be, shall, if possible, give prior written notice
thereof to the Company, NewCo, APP or APP Sub and provide the Company, APP or
APP Sub with the opportunity to contest such disclosure, (iii) the disclosing
party reasonably believes that such disclosure is required in connection with
the defense of a lawsuit against the disclosing party, or (iv) the disclosing
party is the sole and exclusive owner of such Confidential Information as a
result of the Merger or otherwise. In the event of a breach or threatened breach
by the Company, on the one hand, and APP or APP Sub, on the other hand, of the
provisions of this Section, APP, APP Sub, the Surviving Corporation, NewCo and
the Company shall be entitled to an injunction restraining the other party, as
the case may be, from disclosing, in whole or in part, such Confidential
Information. Nothing herein shall be construed as prohibiting any of such
parties from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages.

         Section 16.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, APP Sub, the Surviving Corporation, NewCo and the
Company agree that, in the event of a breach by either of them of the foregoing
covenant, the covenant may be enforced against them by injunctions and
restraining orders.

         Section 16.3 Survival. The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                  Miscellaneous

         Section 17.1 Amendment; Waivers. This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto. Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto. The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 17.2 Assignment. Neither this Agreement nor any right created
hereby or in any agreement entered into in connection with the transactions
contemplated hereby shall be assignable by any party hereto, except by APP to a
wholly owned subsidiary of APP; provided that any such assignment shall not
relieve APP of its obligations hereunder.

         Section 17.3 Parties in Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. APP and APP Sub
acknowledge and agree that the rights and remedies of the Company under this
Agreement will be directly available to the Stockholders as third party
beneficiaries of the rights and remedies of the Company under this Agreement,
including, without limitation, the rights and remedies under Article 14 hereof
to indemnification from APP and APP Sub against Damages incurred by the
Stockholders resulting from a breach by APP or APP Sub of any representation,
warranty or covenant of APP or APP Sub contained herein. Except as provided in
the preceding sentence or as otherwise provided herein, neither this Agreement
nor any other agreement contemplated hereby shall be deemed to confer upon any
person not a party hereto or thereto any rights or remedies hereunder or
thereunder.

         Section 17.4 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior


                                       43
<PAGE>   49
agreements and understandings, both written and oral, among the parties, or any
of them, with respect to the subject matter hereof.

         Section 17.5 Severability. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 17.6 Survival of Representations, Warranties and Covenants. The
representations, warranties and covenants contained herein shall survive the
Closing and all statements contained in any certificate, exhibit or other
instrument delivered by or on behalf of the Company, any Stockholder, APP or APP
Sub pursuant to this Agreement shall be deemed to have been representations and
warranties by the Company, such Stockholder, APP and APP Sub. Notwithstanding
any provision in this Agreement to the contrary, the representations and
warranties contained herein shall survive the Closing until the second
anniversary of the Closing Date except that (a) the representations and
warranties set forth in Section 3.21 with respect to environmental matters shall
survive for a period of ten (10) years, (b) the representations and warranties
set forth in Section 3.30 with respect to tax matters shall survive until such
time as the limitations period has run for all tax periods ended prior to the
Closing Date, (c) the representations and warranties contained in Section 3.27
and Section 3.33 with respect to healthcare matters shall survive for a period
of six (6) years and (d) solely for purposes of Section 14.1(c) and Section
14.2(c), and solely to the extent that any party to be indemnified pursuant to
such provisions actually incurs liability under the Securities Act, the Exchange
Act or any other federal or state securities law, the representations and
warranties set forth therein shall survive until the expiration of any
applicable limitations period.

         Section 17.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF CALIFORNIA.

         Section 17.8 Captions. The captions in this Agreement are for
convenience of reference only and shall not limit or otherwise affect any of the
terms or provisions hereof.

         Section 17.9 Gender and Number. When the context requires, the gender
of all words used herein shall include the masculine, feminine and neuter and
the number of all words shall include the singular and plural.

         Section 17.10 Intentionally omitted.

         Section 17.11 Confidentiality; Publicity and Disclosures. Each party
shall keep this Agreement and its terms confidential, and shall make no press
release or public disclosure, either written or oral, regarding the transactions
contemplated by this Agreement without the prior knowledge and consent of the
other parties hereto; provided that the foregoing shall not prohibit any
disclosure (a) by press release, filing or otherwise that APP has determined in
its good faith judgment and after advice of legal counsel to be required by
federal securities laws or the rules of the National Association of Securities
Dealers, (b) to attorneys, accountants, investment bankers or other agents of
the parties assisting the parties in connection with the transactions
contemplated by this Agreement and (c) by APP in connection with the conduct of
its Initial Public Offering and conducting an examination of the operations and
assets of the Companies; provided that APP shall reasonably promptly provide
notice of any release. In the event that the transactions contemplated hereby
are not consummated for any reason whatsoever, the parties hereto agree not to
disclose or use any Confidential Information they may have concerning the
affairs of the other parties, except for information that is required by law to
be disclosed; provided that should the


                                       44
<PAGE>   50
transactions contemplated hereby not be consummated, nothing contained in this
Section shall be construed to prohibit the parties hereto from operating
businesses in competition with each other.

         Section 17.12 Notice. Whenever this Agreement requires or permits any
notice, request, or demand from one party to another, the notice, request or
demand must be in writing to be effective and shall be deemed to be delivered
and received (i) if personally delivered or if delivered by telex, telegram or
courier service, when delivered to the party to whom notice is sent, (ii) if

         Section 17.13 No Waiver; Remedies. No party hereto shall by any act
(except by written instrument pursuant to Section 17.1 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default in or breach of any of the terms
and conditions hereof. No failure to exercise, nor any delay in exercising, on
the part of any party hereto, any right, power or privilege hereunder shall
operate as a waiver thereof. No single or partial exercise of any right, power
or privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. No remedy set forth in this
Agreement or otherwise conferred upon or reserved to any party shall be
considered exclusive of any other remedy available to any party, but the same
shall be distinct, separate and cumulative and may be exercised from time to
time as often as occasion may arise or as may be deemed expedient.

Company Rights.  The Company has no obligation (contingent or otherwise) to
purchase, redeem or otherwise acquire any of its equity securities or any
interests therein or to pay any dividend or make any distribution in respect
thereof.  Neither the equity structure of the Company nor the relative

         Section 3.12     Litigation and Claims.  There are no claims,
lawsuits, actions, arbitrations, administrative or other proceedings,
governmental investigations or inquiries pending or, to the knowledge of the
Company, threatened against, or affecting the Company, any Company Subsidiary,
any Stockholder, the Physician Employees or any other licensed professional or
other individual affiliated with the Company affecting or that would reasonably
be likely to affect the Company Common Stock or the operations, business
condition, (financial or otherwise), or results of operations of the Company
which (i) if successful, may, individually or in the aggregate, have a Material
Adverse Effect on the Company or (ii) could adversely affect the ability of the
Company or any Company Subsidiary to effect the transactions contemplated
hereby, and to the knowledge of the Company there is no basis for any such
action or any state of facts or occurrence of any event which would reasonably
be likely to give rise to the foregoing.  There are no unsatisfied judgments
against the Company or any Company Subsidiary or any licensed professional or
other individual affiliated with the Company or any Company Subsidiary relating
to services provided on behalf of the Company or any Company Subsidiary or any
consent decrees to which any of the foregoing is subject.  Each of the matters,
if any, set forth in this Section 3.12 is fully covered by policies of
insurance of the Company or any Company Subsidiary as in effect on the date
hereof.

         Section 3.13     No Violation of Law.  Neither the Company nor any
Company Subsidiary has been, nor shall be as of the Effective Time (by virtue
of any action, omission to act, contract to which it is a party or any

state or federal law, ordinance, regulation, order, injunction or decree, or
any other requirement of any governmental body, agency, authority or court
binding on it, or relating to its properties, assets or business or its
advertising, sales or pricing practices, except for violations which,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on the Company.

         Section 3.14     Lease Agreements.  The Disclosure Schedules contain a
true, accurate and complete list of all the lease agreements and license
agreements to which the Company or any Company Subsidiary is a party and
pursuant to which the Company or any Company Subsidiary leases (whether as
lessor or lessee) or licenses (whether as licensor or licensee) any real or
personal property related to the operation of its business and which requires
payments in excess of $12,000 per year (the "Lease Agreements").  The Company
has delivered to APP true and complete copies of all of the Lease Agreements.
Each Lease Agreement is valid, effective and in full force in accordance with
its terms, and there is not under any such lease (i) any existing or claimed
material default by the Company or any Company Subsidiary (as applicable) or
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by the Company or any Company Subsidiary
(as applicable) and, individually or in the aggregate, may reasonably result in
a Material Adverse Effect on the Company, or, (ii) to the knowledge of the
Company, any existing material default by any other party under any of the
Lease Agreements or any event of material default or event which with notice or
lapse of time, or both, would constitute a material default by any such party.
To the knowledge of the Company, there is no pending or threatened reassessment
of any property covered by the Lease Agreements.  The





                                       11

Company or any Company Subsidiary will use reasonable good faith efforts to
obtain, prior to the Effective Time, the consent of each landlord or lessor
whose consent is required to the assignment of the Lease Agreements and will
use reasonable good faith efforts to deliver to APP in writing such consents as
are necessary to effect a valid and binding transfer or assignment of the
Company's or any Company Subsidiary's rights thereunder.  The Company has a
good, clear, valid and enforceable leasehold interest under each of the Lease
Agreements.  The Lease Agreements comply with the exceptions to ownership
interests and compensation arrangements set out in 42 U.S.C. Section  1395nn,
42 C.F.R. Section 1001.952, and any similar applicable state law safe harbor or

including, without limitation, all the property and assets reflected in the
Company Current Financial Statements; and (ii) owns such rights, interests,
assets and property free and clear of all Encumbrances, title defects or
objections (except for taxes not yet due and payable).  The personal property
presently used in connection with the operation of the business of the Company
and the Company Subsidiaries constitutes the necessary personal property assets
to continue operation of the Company and any Company Subsidiary.

         Section 3.16     Indebtedness for Borrowed Money.  Except for trade
payables incurred in the ordinary course of business, the Company does not have
any direct or indirect indebtedness for borrowed money, including indebtedness
by way of lease-purchase arrangements or guarantees, and is not obligated in
any manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

complete list, and the Company has delivered to APP true and complete copies,
of each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate
(other than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the
one hand, and any Payor, government entity, provider, hospital, health

provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the

conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000
in any fiscal year or $25,000 in the aggregate and that are not cancelable by
providing notice of sixty (60) days or less.  All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is
with unrelated third parties and was entered into on an arms-length basis in
the ordinary course of business and, assuming the receipt of the appropriate
consents, all will continue to be binding in accordance with their terms after
consummation

of the transaction contemplated herein; there are no contracts, agreements or
other instruments to which the Company is a party or is bound (other than
physician employment contracts and insurance policies) which could either
singularly or in the aggregate have a Material Adverse Effect on the value to
APP of the assets and properties to be acquired by APP from the Company, or
which could inhibit or prevent the Company from transferring to or vesting in
APP good and sufficient title to the assets and properties to be acquired by
APP and the Surviving Corporation except where the failure to transfer would
not have a Material Adverse Effect on APP.  In every instance where consent is
necessary, the Company shall, on or before the Closing Date, use reasonable
good faith efforts to obtain and deliver to APP in writing, effective as of the
Closing Date, such consents as are necessary to enable the Surviving
Corporation to enjoy all of the rights now enjoyed by the Company under such
contracts.  Any and all such consents shall be in a form reasonably acceptable
to APP and shall contain an acknowledgment by the consenting party that the
Company has fully complied with and is not in default under any provision of
the particular contract or agreement.  Notwithstanding the foregoing, the
Company shall not transfer to APP any contracts or agreements relating to the
provision of professional medical services or other such agreements and
contracts that APP consents to in writing to be transferred to NewCo in the
Spin-off Transaction.  No contract with a health care provider or Payor has
been materially amended or terminated within the last twelve (12) months.

                 (b)      The Company (i) has not received notice of any plan
or intention of any other party to exercise any right to cancel or terminate
any contract, agreement or instrument required to be disclosed pursuant to
Section 3.17(a), and to the knowledge of the Company there are no fact(s) that
would justify the exercise of such a right; and (ii) does not currently
contemplate, or have reason to believe any other Person currently contemplates,
any amendment or change to any such contract, agreement or instrument.

         Section 3.18     Employee Matters.  The Company is not currently a
party to any employment contract (except for oral employment agreements which
are terminable at will), consulting or collective bargaining contracts,

sharing, bonus, stock option, stock purchase or other nonqualified benefit or
compensation commitments, benefit plans, arrangements or plans (whether written
or oral), including all welfare plans (as defined in Section 3(1) of ERISA) of
or pertaining to the Company and any of its present or former employees, or any
predecessors in interest.  As of April 30, 1997, the Company employed a
collective total of [___] part-time and [____] full-time employees.  The

other employees) and bonuses in 1997 in excess of $50,000.  The Company is not
delinquent in payment to any of its employees or Physician Employees for wages,
salaries, bonuses or other direct compensation for any services performed for
it to the date hereof or amounts required to be reimbursed to such employees.
Upon termination of employment of any employee or Physician Employee, no
severance or other payments will become due and the Company has no policy, past

Employee Benefit Plans can be terminated or amended at will by the Company

further contributions or payments in connection therewith following such
termination.  No unwritten amendment exists with respect to any Employee
Benefit Plan.

                 (b)      Administration.  Each Employee Benefit Plan has been

reasonably likely to result, directly or indirectly, (including through any
obligation of indemnification or contribution), in any taxes, penalties or
other liability to APP or any of its Affiliates.

                 (e)      Claims and Litigation.  No pending or, to the
Company's knowledge, threatened, claims, suits or other proceedings exist with

each Employee Benefit Plan subject to Title IV of ERISA, the assets of each
such plan are at least equal in value to the present value of accrued benefits
determined on an ongoing basis as of the date hereof.  With respect to each
Employee Benefit Plan described in Section 501(c)(9) of the Code, the assets of
each such plan are at least equal in value to the present value of accrued
benefits, based upon the most recent actuarial valuation as of a date no more

Company that would result in the imposition of liability against APP or any of
its Affiliates by the Pension Benefit Guaranty Corporation ("PBGC") as a result
of any act or omission by the Company or any member of a Controlled Group.  No
reportable event (within the meaning of Section 4043 of ERISA) for which the

Employee Benefit Plan subject to the requirements of Title IV of ERISA.

                 (k)      Retirees.  The Company has no obligation or
commitment to provide medical, dental or life insurance benefits to or on
behalf of any of its employees who may retire or any of its former employees
who have retired except as may be required pursuant to the continuation of
coverage provisions of Section 4980B of the Code and the applicable provisions
of ERISA.

                 (l)      Other Compensation Arrangements.  Neither the Company

(as defined in subsection (e) below) for the Company under any applicable
Environmental Law that had, or would reasonably be likely to have, a Material
Adverse Effect on the Company.  Neither the Company nor any Company Subsidiary
has engaged in any activity or failed to undertake any activity which action or
failure to act has given, or would reasonably be likely to give, rise to any

The Disclosure Schedules disclose any known presence of asbestos in or on the

         Section 3.22     Filing Reports.  All returns, reports, plans and
filings of any kind or nature necessary to be filed by the Company with any
governmental agency or authority have been properly completed and timely filed
in compliance with all applicable requirements, except where failure to so file
would not have a Material Adverse Effect on the Company.

         Section 3.23     Insurance Policies.  The Disclosure Schedules list
and briefly describe the Company's policies of insurance to which the Company
or any Company Subsidiary is a party or under which the Company or any Company
Subsidiary, officer or director thereof is or has been covered at any time
during the last five (5) years preceding the date of this Agreement relating to
the business of the Company or any Company Subsidiary (the "Insurance
Policies").  All of the Insurance Policies are valid, outstanding and
enforceable policies, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies and all premiums with respect thereto which
are due and payable are currently paid.  All Insurance Policies currently
maintained by the Company or any Company Subsidiary ("Current Policies") taken
together, (i) provide adequate insurance coverage for the assets, properties
and operations of the Company and its Affiliates for all risks normally insured
against by a Person carrying on a substantially similar business or businesses

legal and contractual requirements to which the Company or any of its
Affiliates is a party or by which any of them may be bound, and (iii) shall be
maintained in force (including the payment of all premiums and compliance with
their terms) without interruption up to and including the Closing Date.  True,
complete and correct copies of all Insurance Policies have been provided to
APP.  Neither the Company nor any Company Subsidiary nor any officer or
director thereof has received any notice or other written communication from
any issuer of any Current Policy cancelling such policy, materially increasing
any deductibles or retained amounts thereunder, or materially increasing the
annual or other premiums payable thereunder and, to the knowledge of the
Company, no such cancellation or increase of deductibles, retainages or
premiums is threatened.  There are no outstanding claims, settlements or
premiums owed against any Insurance Policy, and all required notices have been
given and all known potential or actual claims under any Insurance Policy have
been presented in due and timely fashion.  Within the five (5) years preceding
the Agreement, neither the Company nor any Company Subsidiary has filed a
written application for any professional liability insurance coverage which has
been denied by an insurance agency or carrier.  The Disclosure Schedules also
set forth a list of all claims under any Insurance Policy in excess of $10,000
per occurrence filed by the Company or any Company Subsidiary during the
immediately preceding three-year period.  Each Physician Employee has, at all
times while a Physician Employee, maintained or been covered by professional
malpractice insurance in such types and amounts as are customary for such a
physician practicing the same type of medicine in the same geographic area.

         Section 3.24     Accounts Receivable; Payors.

                 (a)      The Disclosure Schedules set forth a list and aging
of all accounts receivable of the Company as of March 31, 1997, which list is
complete, true and accurate in all material respects.  All such accounts
receivable arose in the ordinary course of business and have not been
previously written off as bad debts and, are, to the extent still uncollected,
to the knowledge of the Company collectible in the ordinary course of business,
net of reserves for doubtful and uncollectible accounts shown in the Company
Financial Statements or on the accounting records of the Company (which
reserves are calculated consistent with generally accepted accounting
principles and past practice).

                 (b)      The Disclosure Schedules set forth (i) a true,
correct and complete list of the names and addresses of each Payor of the
Company as of such date, which accounted for more than 5% of the revenues of
the Company in the fiscal year ended December 31, 1996, or which is reasonably
expected to account for more than 5% of the revenues of the Company for the
fiscal year to end December 31, 1997, and (ii) a single line item listing for
all private-pay patients in the aggregate of the Company.  The Company has
satisfactory relations with such Payors set forth in (i) above and none of such
Payors has notified the Company that it intends to discontinue its relationship
with the Company or to deny any payments due from, or any claims for payment
submitted to any such party.

non-Physician Employee providers of care to patients) which accounted for a
dollar volume of purchases paid for by the Company in excess of $25,000 for the
fiscal year ended December 31, 1996, or which is reasonably expected to account
for a dollar volume of purchases paid for by the Company in excess of $25,000
for the fiscal year to end December 31, 1997.

         Section 3.26     Inventory.  All items of inventory on the Company
Current Balance Sheet contained in the Company Financial Statements consisted,
and all such items on hand on the date of this Agreement consist, and all such
items on hand at the Effective Time will consist, net of all applicable
reserves with respect thereto (calculated consistent with past practice), of
items of a quality and a quantity usable and saleable in the ordinary course of
the Company's business and conform to generally accepted standards in the
industry of which the Company is a part.  The value of the inventories
reflected on the Company Current Balance Sheet contained in the Company
Financial Statements are net of adequate reserves for damaged, excess, and
unusable items.  Purchase commitments of the Company for inventory are not
materially in excess of normal requirements, and none of such purchase
commitments are at prices in excess of prevailing market prices at the time of
such purchase commitment.

         Section 3.27     Licenses, Authorization and Provider Programs.

Social Security Act (the "Medicare and Medicaid Programs") and any other

("Governmental Programs").  The Company, the Stockholders, and each Physician
Employee has a current provider number for such Governmental Programs and with
such private non-governmental programs (including without limitation any
private insurance program) under which the Company is presently receiving
payments directly or indirectly from any Payor for patient care provided by
such Physician Employee, licensed employee or independent contractor (such
non-governmental programs herein referred to as "Private Programs").  A true,
correct and complete list of such licenses, permits and other authorizations
(including, but not limited to verification of Medicare and Medicaid provider
numbers and participating physician contracts under 1842(h) of the Social
Security Act), and provider agreements, is set forth in the Disclosure
Schedules, true, complete and correct copies of which have been provided to
APP.  No violation, default, order or deficiency exists with respect to any of
the items listed in the Disclosure Schedules except for such violations,
defaults, orders or deficiencies which would not be reasonably likely to have a
Material Adverse Effect on the Company, and there is no action pending or to
the Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program,
and no event has occurred which, with or without notice or lapse of time, or
both, would constitute grounds for a violation, order or deficiency with
respect to any of the items listed in the Disclosure Schedules to revoke,
withdraw or suspend any material license to operate its business as is
presently being conducted by it.  To the knowledge of the Company, there has
been no decision not to renew any existing agreement with any provider or Payor

the Company, or any Physician Employee, nor the right of any licensed
professional or other individual affiliated with the Company to receive
reimbursements pursuant to any Governmental Program or Private Program has been
terminated or otherwise materially and adversely affected as a result of any
investigation or action whether by any federal or state governmental regulatory
authority or other third party.  No Physician Employee, licensed professional
or other individual affiliated with the business has, during the past three (3)
years prior to the Effective Time, had their professional license or staff
privileges limited, suspended or revoked by any governmental regulatory
authority or agency, hospital, integrated delivery system, trade association,
professional review organization, accrediting organization or certifying agency

APP on any matter.  There exist no options, warrants, subscriptions, calls,
commitments or other rights to purchase, or securities convertible into or
exchangeable for, any of the authorized or outstanding securities of APP and no

kind exists which obligates APP to issue any of its authorized but unissued

Consents.  The execution, delivery and performance of this Agreement by APP and
any other documents contemplated hereby (with or without the giving of notice,
the lapse of time, or both): (i) does not require the consent of any
governmental or regulatory body or authority or any other third party except
for such consents, for which the failure to obtain would not result in a
Material Adverse Effect on APP; (ii) will not conflict with any provision of
APP's certificate of incorporation or bylaws; (iii) will not conflict with,
result in a violation of, or constitute a default under any law, ordinance,
regulation, ruling, judgment, order or injunction of any court or governmental

properties are bound except for such conflict, termination, breach or default,
the occurrence of which would not result in a Material Adverse Effect on APP;
and (v) will not create any Encumbrance or restriction upon APP Common Stock or
any of the assets or properties of APP.  The financial statements of APP

                                   ARTICLE V

           Closing Date Representations and Warranties of the Company

         The Company represents and warrants that the following will be true
and correct on the Closing Date as if made on that date:

         Section 5.1      Organization and Good Standing; Qualification.  NewCo
is a professional corporation duly organized, validly existing and in good
standing under the laws of its state of organization, with all requisite
corporate power and authority to carry on the business in which it intends to
engage, to own the properties it intends to own, and to execute and deliver the
Service Agreement, the Security Agreement and the Physician Employment
Agreements and consummate the transactions and perform the services
contemplated thereby.  NewCo is duly qualified and licensed to do business and
is in good standing in all jurisdictions where the nature of its intended
business makes such qualification necessary, which jurisdictions are listed in
the Disclosure Schedules, except where the failure to be so qualified shall not
have a Material Adverse Effect on NewCo.

         Section 5.2      Capitalization.  The authorized capital stock of
NewCo consists of [_____] shares of NewCo Common Stock, of which [______]
shares are issued and outstanding, and no shares of capital stock of NewCo are
held in treasury.  The Stockholders own all of the issued and outstanding
shares of NewCo Common Stock, free and clear of any Encumbrance.  Each
outstanding share of NewCo Common Stock has been legally and validly issued and
is fully paid and nonassessable.  There exist no options, warrants,
subscriptions or other rights to purchase, or securities convertible into or
exchangeable for, any of the authorized or outstanding securities of NewCo.  No
shares of capital stock of NewCo have been issued or disposed of in violation
of the preemptive rights, rights of first refusal or similar rights of any of
NewCo's stockholders.


         Section 5.3      Corporate Records.  The copies of the articles or
certificate of incorporation and bylaws, and all amendments thereto, of NewCo
that have been delivered or made available to APP are true, correct and
complete copies thereof, as in effect on the Closing Date.

         Section 5.4      Authorization and Validity.  The execution, delivery
and performance by NewCo of the Service Agreement, the Security Agreement, the
Physician Employment Agreements and the other agreements contemplated thereby,
and the consummation of the transactions and provision of services contemplated
thereby, have been duly authorized by the Board of Directors of NewCo.  The
Service Agreement, the Security Agreement, the Physician Employment Agreements
and each other agreement contemplated thereby will be as of the Closing Date
duly executed and delivered by NewCo and will constitute valid and binding
obligations of NewCo enforceable against NewCo in accordance with their
respective terms, except as may be limited by applicable bankruptcy, or other
laws affecting creditors' rights generally, or by general equity principles, or
by public policy.

         Section 5.5      No Violation.  Neither the execution, delivery or
performance of the Service Agreement, the Security Agreement, the Physician
Employment Agreements or the other agreements contemplated thereby nor the
consummation of the transactions or provision of services contemplated thereby
will (a) conflict with, or result in a violation or breach of the terms,
conditions or provisions of, or constitute a default under, the articles or
certificate of incorporation or bylaws of NewCo, or (b) violate or conflict
with any applicable local, state or federal law, ordinance, regulation, order,
injunction or





                                       26

decree, or any other requirement of any governmental body, agency or authority
or court binding on it, or relating to its property or business.

         Section 5.6      No Business, Agreements, Assets or Liabilities.
NewCo has not commenced business since its incorporation.  Other than its
articles or certificate of incorporation and bylaws, and as of the Closing
Date, the Service Agreement, the Security Agreement, the Physician Employment
Agreements, and the other contracts and agreements assigned to NewCo as part of
the Spin-Off Transaction, NewCo is not a party to or subject to any agreement,
indenture or other instrument.  NewCo does not own any assets (tangible or
intangible) other than the consideration received upon the issuance of shares
of its capital stock or pursuant to the Spin-Off Transaction, and NewCo does
not have any liabilities, accrued, contingent or otherwise (known or unknown
and asserted or unasserted) other than those assumed pursuant to the Spin-Off
Transaction.

         Section 5.7      Compliance with Laws.  NewCo has complied with all
applicable laws, regulations and licensing requirements and has filed with the
proper authorities all necessary statements and reports, except where failure
to so comply or file would not, individually or in the aggregate, have a
Material Adverse Effect on NewCo.

Directors of the Company shall recommend the approval of the Merger by the
Stockholders of the Company.  If the Stockholders' approval is not unanimous,
the Company shall give notice to the nonconsenting Stockholders of the action
taken by the consenting Stockholders as may be required by applicable law;
provided, however, that this covenant shall not require the Company to make any
expenditures that are not expressly set forth in this Agreement or otherwise
contemplated herein.

         Section 7.9      Obligations of Company and Stockholders.  Subject to
Section 7.8 hereof, the Company will take all action reasonably necessary to
cause the Company to perform its obligations under this Agreement and all

whatsoever arising from any tax-qualified plan as required under applicable
law.  The Company acknowledges that the purpose and intent of this covenant is
to assure that APP shall have no liability whatsoever at any time after the
Closing Date with respect to any such tax-qualified plan, unless such plan is
merged with a plan sponsored by APP.

         Section 7.11     Accounting and Tax Matters.  The Company will not
change in any material respect the accounting methods or practices followed by
the Company (including any material change in any assumption underlying, or any

organize and incorporate NewCo in the state of New York, and the articles or

documents, agreements or instruments necessary pursuant to and in compliance
with applicable law to effect the Spin-Off Transaction, including without
limitation, the following:  Prior to the Closing, the Company shall transfer to

interest in and to the Employee Benefit Plans, all contracts and agreements and
other assets listed on the Disclosure Schedules (to be delivered by the Company
prior to Closing, which schedule will be subject to the approval of APP, which
approval shall not be unreasonably withheld) which by law either cannot be
acquired or cannot be used by APP because they relate to the practice of
medicine or radiology, and shall contribute to NewCo such other consideration
and assets of the Company as may be required under applicable law, in exchange
for the issuance by NewCo of shares of NewCo Common Stock, such shares being
all of the issued and outstanding shares of NewCo Common Stock.  The Company
shall then distribute the shares of NewCo Common Stock to the Stockholders in
proportion to their respective ownership interest in the Company.

The Company shall prepare and execute all documents necessary to effectuate the
"F" Reorganization prior to the Closing.  At or prior to the Closing, the
Company shall cause an amendment to this Agreement to be executed which will
reflect the changes which result from the "F" Reorganization.

reasonably necessary to cause the consummation of the transactions contemplated
hereby in accordance with their terms and conditions and take all corporate and

APP will use its best efforts to take, or cause to be taken, all actions
necessary to effect the Merger under applicable law, including without
limitation the filing with the appropriate government officials of all

records and information with respect to the affairs of APP as the Company and
their representatives may reasonably request, all for the sole purpose of

Company or the Stockholders shall diminish or otherwise affect any of the
representations, warranties, covenants or agreements of APP under this
Agreement.

inform the Company in writing of (a) any notice of, or other communication
relating to, a default or event that, with notice or lapse of time or both,

Agreement and prior to the Effective Time under any contract, agreement or
investment material to APP's condition (financial or otherwise), operations,
assets, liabilities or business and to which it is subject; (b) any material
adverse change in APP's condition (financial or otherwise), operations, assets,

use their best efforts to establish a qualified plan and trust for NewCo,
within the meaning of Section 401(a) and 501(a), respectively, of the Code
("New Qualified Plan") that will provide benefits comparable (as determined
under Section 401(a)(4) of the Code) to the benefits provided under the
qualified plans referenced in the Disclosure Schedules, if any, sponsored by
the Company as of March 31, 1997.  APP will file for a favorable determination
letter from the IRS on the New Qualified Plan and request a favorable
determination from the IRS that NewCo is not a member of an affiliated service
group (as defined in Section 414(m) of the Code) or a recipient organization of
leased employee services (as defined in Section 414(n) of the Code).  Any
benefits provided under the New Qualified Plan shall be conditioned on a
favorable determination letter from the IRS.  Costs associated with the
establishment and design of the New Qualified Plan shall be paid by APP or APP
Sub.  The NewCo shall be responsible for funding any contributions to, or any
ongoing administrative costs of, the New Qualified Plan.

         (a)     The Company shall cooperate with APP to promptly prepare and
file with the SEC the Registration Statements on Form S-1 and Form S-4 (or
other appropriate Forms) to be filed by APP in connection with its Initial
Public Offering and offering of the shares of APP Common Stock to the Target
Interest Holders pursuant to the transactions contemplated by this Agreement
and the Other Agreements (including the prospectus constituting parts thereof,

information concerning the Company and NewCo as may be reasonably requested in
connection with any such action in a timely manner.

         (b)     The Company and APP and each separately represent and warrant
that (i) in the case of the Company, none of the written information or
documents supplied or to be supplied by it specifically for inclusion in the
Registration Statements, by exhibit or otherwise and (ii) in the case of APP,
will, at the time the Registration Statements and each amendment and supplement
thereto, if any, becomes effective under the Securities Act, none of them
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.
The Company shall be entitled to review the Registration Statements and each of
the amendments thereto, if any, prior to the time each becomes effective under
the Securities Act.  The Company shall have no responsibility for information
contained in the Registration Statements except for information provided by the

information concerning itself, its subsidiaries, directors, officers, partners,
Stockholders and NewCo, and such other matters as may be reasonably requested

subsidiaries to any governmental entity in connection with the Merger and the
other transactions contemplated by this Agreement.

that, with respect to the representations and warranties of such party
contained in this Agreement, such party shall have the continuing obligation
until the Closing to supplement or amend promptly the Disclosure Schedules with
respect to any matter that would have been or would be required to be set forth
or described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Schedule that constitutes or reflects a
Material Adverse Effect on the Company may be made unless APP consents to such
amendment or supplement, and no amendment or supplement to a Disclosure
Schedule that constitutes or reflects a Material Adverse Effect on APP may be
made unless the Company consents to such amendment or supplement.  For purposes
of this Agreement, including without limitation for purposes of determining
whether the conditions set forth in Sections 10.1 and 11.1 have been fulfilled,
the Disclosure Schedules hereto shall be deemed to be the Disclosure Schedules
as amended or supplemented pursuant to this Section 9.2.  In the event that the
Company seeks to amend or supplement a Disclosure Schedule pursuant to this
Section 9.2 and APP does not consent to such amendment or supplement, or APP
seeks to amend or supplement a Disclosure Schedule pursuant to this Section
9.2, and the Company does not consent, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 15.1(a) hereof.

         Section 9.3      Actions Contrary to Stated Intent.  No party hereto
will knowingly, either before or after the Merger, take any action that would
prevent the Merger from qualifying as a tax-free exchange within the meaning of
Section 351 of the Code.

         Section 9.4      Public Announcements.  The parties hereto will
consult with each other before issuing any press release or making any public
statement with respect to this Agreement and the transactions contemplated
hereby and, except as may be required by applicable law, will not issue any
such press release or make any such public statement prior to such
consultation, although the foregoing shall not apply to any disclosure by APP
in any filing with the DOJ, FTC or SEC.

         Section 9.5      Expenses.  Each party to this Agreement shall be
solely responsible for their own fees and expenses with respect to the
transactions contemplated herein including, without limitation, the fees
charged by attorneys, accountants and financial advisors retained by such
parties.  The fees and expenses incurred by the Company and NewCo in connection
with the Merger shall be paid by the Company in full immediately prior to the
Closing and such expenses shall be the sole responsibility of the Stockholders
following the Closing Date and not APP.

         Section 9.6      Patient Confidentiality.  APP shall agree to keep all
records and information regarding the patients of the Company and NewCo
confidential in accordance with all applicable laws.

         Section 9.7      Registration Statements.  APP shall prepare and file
the Registration Statements with the SEC, and shall use its reasonable good
faith efforts to cause the Registration Statements to become effective under

                              Post Closing Matters

         Section 13.1     Further Instruments of Transfer.  Following the
Closing, at the request of APP or the Surviving Corporation and at APP's sole
cost and expense, the Stockholders and the Company shall deliver any further
instruments of transfer and take all reasonable action as may be necessary or
appropriate to carry out the purpose and intent of this Agreement.  Following
the Closing, at the request of NewCo and at NewCo's sole cost and expense, APP
or the Surviving Corporation shall deliver any further instruments of transfer
and take all reasonable action as may be necessary and appropriate to carry out
the purpose and intent of this Agreement.

         Section 13.2     Merger Tax Covenant.

         (a)     The parties intend that the Merger will qualify as a tax-free
transaction under Section 351 of the Code in which the Company will not
recognize gain or loss, and pursuant to which any gain recognized by a
Stockholder as a result of the Merger will not exceed the amount of any cash
received by a Stockholder in the Merger (a "Reorganization").

         (b)     Both prior to and after the Effective Time, all books and
records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Merger being treated as a Reorganization.
These obligations are excused as to a party required to maintain the books or
file a Tax Return if such party has provided to the other parties a written
opinion of competent tax counsel to the effect that there is not substantial
authority, within the meaning of Section 6662(d)(2)(B)(i) of the Code, to
report the Merger as a Reorganization and such opinion either is furnished
prior to the Effective Time or is based on facts or events not known at the
Effective Time.  Each party shall provide to each other party such tax
information, reports, returns, or schedules as may be reasonably required to
assist such party in accounting for and reporting the Merger as a
Reorganization.

         (c)     The parties agree that no Stockholder shall be liable for any
taxes incurred by the Company and for which APP has successor liability
therefor which arise solely as a result of the Merger or the consummation of
the transactions contemplated hereby; provided that the foregoing shall not
limit or otherwise be deemed a waiver of any right of indemnification under
Section 14.1 for a breach of any representation, warranty or covenant of the
Company or any Stockholder.

         Section 13.3     Current Public Information.  APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

                                  ARTICLE XIV

                                    Remedies

         Section 14.1     Indemnification by the Company.  Subject to the terms
and conditions of this Article XIV, the Company agrees to indemnify, defend and
hold APP and the Surviving Corporation and their respective directors,
officers, stockholders, employees, agents, attorneys, consultants and
Affiliates harmless from and against all losses, claims, obligations, demands,
assessments, penalties, liabilities, costs, damages, reasonable attorneys' fees
and expenses (including, without limitation, all costs of experts and all costs
incidental to or in connection with any appellate process) (collectively,
"Damages") asserted against or incurred by such individuals and/or entities
arising out of or resulting from:

                 (a)      a breach by the Company of any representation or
warranty (without giving effect to any Material Adverse Effect qualifier
contained as part of any such representation or warranty) or covenant of the
Company contained in this Agreement or in any Schedule or certificate delivered
thereunder;

                 (b)      any violation (or alleged violation) by the Company
and/or any of its past or present directors, officers, partners, stockholders,
employees (including, without limitation, any Physician Employee), agents,
attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons
in which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                 (c)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any (i) untrue
statement of a material fact in any Registration Statement or any prospectus
forming or part thereof, or any amendment thereof or supplement thereto
relating to the Company (including any Company Subsidiary) or NewCo required to
be stated therein or (ii) failure to state information necessary to make the
statements therein not misleading, which untrue statement or failure to state
information arises or results solely from information provided in writing to
APP or its counsel by the Company or any Stockholder or their agents
specifically for inclusion in any such Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto.

         Section 14.2     Indemnification by APP.  Subject to the terms and
conditions of this Article XIV, APP hereby agrees to indemnify, defend and hold
the Stockholders, the Company and NewCo and their respective directors,
officers, stockholders, employees, agents, attorneys, consultants and
Affiliates harmless from and against all Damages asserted against or incurred
by such individuals and/or entities arising out of or resulting from:

                 (a)      a breach by APP of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of APP contained in
this Agreement or in any schedule or certificate delivered hereunder; and

                 (b)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any untrue statements
of material fact in any Registration Statement or any prospectus forming a part





                                       39

<PAGE>   46
thereof, or any amendment thereof or supplement thereto, or required to be
stated therein or failure to state information necessary to make the statements
therein not misleading (except for any liability based upon any actual or
alleged untrue statement of material fact or an omission to state a material
fact relating to NewCo, the Company or any Stockholder to the extent derived
from any information provided in writing by the Company or a Company Subsidiary
or any of their agents contained in the representations and warranties set
forth in this Agreement or any certificate, exhibit, schedule or instrument
required to be delivered under this Agreement.)

                 Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
of any of the parties hereto of any liability or limit any liability that it
may have in the case of fraud in connection with the transactions contemplated
by this Agreement.

         Section 14.3     Conditions of Indemnification.  All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                 (a)      Any party claiming indemnification under the
Agreement (an "Indemnified Party") shall promptly (and, in the event, at least
ten (10) days prior to the due date for any responsive pleadings, filings or
other documents) (i) notify the party for whom indemnification is sought (the
"Indemnifying Party) of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying
Party a written notice ("Claim Notice") describing in reasonable detail the
nature of the Third Party Claim, a copy of all papers served with respect to
such claim (if any), an estimate of the amount of Damages attributable to the
Third Party Claim and the basis of the Indemnified Party's request for
indemnification under this Agreement.  The failure to promptly deliver a Claim
Notice shall not relieve any Indemnifying Party of its obligations to any
Indemnified Party with respect to the related Third Party Claim except to the
extent that the resulting delay is materially prejudicial to the defense of
such claim.  Within thirty (30) days after receipt of any Claim Notice (the
"Election Period"), the Indemnifying Party shall notify the Indemnified Party
(x) whether the Indemnifying Party disputes its potential liability to the
Indemnified Party under this Article XIV with respect to such Third Party Claim
and (y) whether the Indemnifying Party desires, at the sole cost and expense of
such Indemnifying Party, to defend the Indemnified Party against such Third
Party Claim.

                 (b)      If the Indemnifying Party notifies the Indemnified
Party within the Election Period that the Indemnifying Party elects to assume
the defense of the Third Party Claim, then the Indemnifying Party shall have
the right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b).  Except as set
forth in Section 14.3(f) below, the Indemnifying Party shall have full control
of such defense and proceedings, including any compromise or settlement
thereof.  The Indemnified Party is hereby authorized, at the sole cost and
expense of the Indemnifying Party (but only if the Indemnified Party is
entitled to indemnification hereunder), to file, during the Election Period,
any motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Party and not prejudicial to the Indemnifying Party.  If requested by the
Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense
of the Indemnifying Party, to cooperate with the Indemnifying Party and their
counsel in contesting any Third Party Claim that the Indemnifying Party elects
to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person.  The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Party pursuant to this Section 14.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those





                                       40

<PAGE>   47
available to the Indemnifying Party, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Party, and upon written
notification thereof, the Indemnifying Party shall not have the right to assume
the defense of such action on behalf of the Indemnified Party; provided further
that the Indemnifying Party shall not, in connection with any one such action
or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party.  Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                 (c)      If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 14.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
14.3(b) but fails diligently and promptly to prosecute or settle the Third
Party Claim, then the Indemnified Party shall have the right to defend, at the
sole cost and expense of the Indemnifying Party (if the Indemnified Party is
entitled to indemnification hereunder), the Third Party Claim by all
appropriate proceedings, which proceedings shall be promptly and vigorously
prosecuted by the Indemnified Party to a final conclusion or settled.  The
Indemnified Party shall have full control of such defense and proceedings,
provided, however, that the Indemnified Party may not enter into, without the
Indemnifying Party's consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim.  Notwithstanding the
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes their
potential liability to the Indemnified Party under this Article XIV and if such
dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party
shall not be required to bear the costs and expenses of the Indemnified Party's
defense pursuant to this Section or of the Indemnifying Party's participation
therein at the Indemnified Party's request, and the Indemnified Party shall
reimburse the Indemnifying Party in full for all costs and expenses of such
litigation.  The Indemnifying Party may participate in, but not control, any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 14.3(c), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnifying Party
has been advised by counsel that there may be one or more legal defenses
available to it that are different from or additional to those available to the
Indemnified Party, then the Indemnifying Party may employ separate counsel and
upon written notification thereof, the Indemnified Party shall not have the
right to assume the defense of such action on behalf of the Indemnifying Party.

                 (d)      In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification
under this Agreement.  If the Indemnifying Party does not notify the
Indemnified Party within sixty (60) days from its receipt of the Indemnity
Notice that the Indemnifying Party disputes such claim, the claim specified by
the Indemnified Party in the Indemnity Notice shall be deemed a liability of
the Indemnifying Party hereunder.  If the Indemnifying Party has timely
disputed such claim, as provided above, such dispute shall be resolved by
litigation in an appropriate court of competent jurisdiction if the parties do
not reach a settlement of such dispute within thirty (30) days after notice of
a dispute is given.

                 (e)      Payments of all amounts owing by any Indemnifying
Party pursuant to this Article XIV relating to a Third Party Claim shall be
made within thirty (30) days after the latest of (i) the settlement of such
Third Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.  Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after





                                       41

<PAGE>   48
the later of (i) the expiration of the 60-day Indemnity Notice period or (ii)
the expiration of the period for appeal of a final adjudication of the
Indemnifying Party's liability to the Indemnified Party under this Agreement.

                 (f)      The Indemnifying Party shall provide the Indemnified
Party with written notice of any firm offer that is made to settle or
compromise a Third Party Claim against an Indemnified Party.  If a firm offer
is made to settle such a claim solely by the payment of money damages and the
Indemnifying Party notifies the Indemnified Party in writing that the
Indemnifying Party agrees to such settlement, but the Indemnified Party elects
not to accept and agree to it, the Indemnified Party may continue to contest or
defend such Third Party Claim and, in such event, the total maximum liability
of the Indemnifying Party to indemnify or otherwise reimburse the Indemnified
Party hereunder with respect to such a claim shall be limited to and shall not
exceed the amount of such settlement offer, plus reasonable out-of-pocket costs
and reasonable expenses (including reasonable attorneys' fees and
disbursements) to the date of notice that the Indemnifying Party desired to
accept such settlement.

                 (g)      Notwithstanding any provision herein to the contrary,
the obligation of an Indemnifying Party to provide indemnification to an
Indemnified Party for breach of any representation or warranty as provided in
Sections 14.1(a) or 14.2(a) hereof shall not take effect unless and until the
Damages asserted against or incurred in the aggregate and on a collective basis
by the Indemnified Parties pursuant to either Section 14.1 or 14.2 (as
applicable) as a result of such a breach or breaches exceeds $100,000.

         Section 14.4     Costs, Expenses and Legal Fees.  Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 14.5     Tax Benefits; Insurance Proceeds.  The total amount
of any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

                                   ARTICLE XV

                                  Termination

         Section 15.1     Termination.  This Agreement may be terminated and
the Merger and the Acquisitions may be abandoned:

                 (a)      at any time prior to the Effective Date by mutual
agreement of all parties;

                 (b)      at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and
delivered by the Company or any Stockholder pursuant to this Agreement is or
becomes untrue or breached in any material respect or if the Company or any
Stockholder fails to comply in any material respect with any material covenant
or agreement contained herein, and any such misrepresentation, noncompliance or
breach is not cured, waived or eliminated within thirty (30) days after receipt
of written notice thereof;

                 (c)      at any time prior to the Effective Date by the
Company if any representation or warranty of APP contained in this Agreement or
in any certificate or other document executed and delivered by APP pursuant to
this Agreement is or becomes untrue in any material respect or if APP fails





                                       42

<PAGE>   49
to comply in any material respect with any covenant or agreement contained
herein, and any such misrepresentation, noncompliance or breach is not cured,
waived or eliminated within thirty (30) days after receipt of written notice
thereof;

                 (d)      at any time prior to the Effective Date by APP if, as
a result of the conduct of due diligence and regulatory compliance procedures,
APP deems termination to be advisable; or

                 (e)      by APP or the Company if the Merger shall not have
been consummated by September 30, 1997.

         Section 15.2     Effect of Termination.  Except as set forth in
Section 16.3, in the event this Agreement is terminated pursuant to this
Article XV, this Agreement shall forthwith become void.

                                  ARTICLE XVI

                   Nondisclosure of Confidential Information

         Section 16.1     Non-Disclosure Covenant.  The Company and NewCo
recognize and acknowledge that each has in the past, currently has, and in the
future may possibly have, access to certain Confidential Information of APP and
the Surviving Corporation that is valuable, special and a unique asset of such
entity's business.  APP acknowledges that it had in the past, currently has,
and in the future may possibly have, access to certain Confidential Information
of the Company and NewCo that is valuable, special and a unique asset of each
such business.  The Company, NewCo and APP, severally, agree that they will not
disclose such Confidential Information to any person, firm, corporation,
association or other entity for any purpose or reason whatsoever, except (a) to
authorized representatives of APP, NewCo and the Company and (b) to counsel and
other advisers to APP, NewCo and the Company provided that such advisers (other
than counsel) agree to the confidentiality provisions of this Section 16.1,
unless (i) such information becomes available to or known by the public
generally through no fault of the Company, NewCo or APP, as the case may be,
(ii) disclosure is required by law or the order of any governmental authority
under color of law, provided, that prior to disclosing any information pursuant
to this clause (ii) the Company, NewCo or APP, as the case may be, shall, if
possible, give prior written notice thereof to the Company, NewCo or APP and
provide the Company or APP with the opportunity to contest such disclosure,
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, or
(iv) the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Merger or otherwise.  In the event of a breach
or threatened breach by the Company, on the one hand, and APP, on the other
hand, of the provisions of this Section, APP, NewCo and the Company shall be
entitled to an injunction restraining the other party, as the case may be, from
disclosing, in whole or in part, such Confidential Information.  Nothing herein
shall be construed as prohibiting any of such parties from pursuing any other
available remedy for such breach or threatened breach, including the recovery
of damages.

         Section 16.2     Damages.  Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, NewCo and the Company agree
that, in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

         Section 16.3     Survival.  The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                 Miscellaneous





                                       43

<PAGE>   50
         Section 17.1     Amendment; Waivers.  This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto.  Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto.  The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 17.2     Assignment.  Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any party hereto,
except by APP to a wholly owned subsidiary of APP; provided that any such
assignment shall not relieve APP of its obligations hereunder.

         Section 17.3     Parties in Interest; No Third Party Beneficiaries.
Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto.  APP
acknowledges and agrees that the rights and remedies of the Company under this
Agreement will be directly available to the Stockholders as third party
beneficiaries of the rights and remedies of the Company under this Agreement,
including, without limitation, the rights and remedies under Article 14 hereof
to indemnification from APP against Damages incurred by the Stockholders
resulting from a breach by APP of any representation, warranty or covenant of
APP contained herein.  Except as provided in the preceding sentence or as
otherwise provided herein, neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party
hereto or thereto any rights or remedies hereunder or thereunder.

         Section 17.4     Entire Agreement.  This Agreement and the agreements
contemplated hereby or delivered in connection herewith constitute the entire
agreement of the parties regarding the subject matter hereof, and supersede all
prior agreements and understandings, both written and oral, among the parties,
or any of them, with respect to the subject matter hereof.

         Section 17.5     Severability.  If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable

which (i) if successful, may, individually or in the aggregate, have a Material
Adverse Effect on the Company or (ii) could adversely affect the ability of the
Company or any Company Subsidiary to effect the transactions contemplated
hereby, and to the knowledge of the Company there is no basis for any such

against the Company or any Company Subsidiary or any licensed professional or
other individual affiliated with the Company or any Company Subsidiary relating
to services provided on behalf of the Company or any Company Subsidiary or any
consent decrees to which any of the foregoing is subject.  Each of the matters,

insurance of the Company or any Company Subsidiary as in effect on the date
hereof.

         Section 3.13     No Violation of Law.  Neither the Company nor any
Company Subsidiary has been, nor shall be as of the Effective Time (by virtue
of any action, omission to act, contract to which it is a party or any

any other requirement of any governmental body, agency, authority or court
binding on it, or relating to its properties, assets or business or its
advertising, sales or pricing practices, except for violations which,

payments in excess of $12,000 per year (the "Lease Agreements").  The Company
has delivered to APP true and complete copies of all of the Lease Agreements.
Each Lease Agreement is valid, effective and in full force in accordance with
its terms, and there is not under any such lease (i) any existing or claimed
material default by the Company or any Company Subsidiary (as applicable) or
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by the Company or any Company Subsidiary
(as applicable) and, individually or in the aggregate, may reasonably result in
a Material Adverse Effect on the Company, or, (ii) to the knowledge of the
Company, any existing material default by any other party under any of the
Lease Agreements or any event of material default or event which with notice or
lapse of time, or both, would constitute a material default by any such party.
To the knowledge of the Company, there is no pending or threatened reassessment
of any property covered by the Lease Agreements.  The

                                       11

whose consent is required to the assignment of the Lease Agreements and will
use reasonable good faith efforts to deliver to APP in writing such consents as

Company's or any Company Subsidiary's rights thereunder.  The Company has a
good, clear, valid and enforceable leasehold interest under each of the Lease
Agreements.  The Lease Agreements comply with the exceptions to ownership
interests and compensation arrangements set out in 42 U.S.C. Section  1395nn,
42 C.F.R. Section 1001.952, and any similar applicable state law safe harbor or

including, without limitation, all the property and assets reflected in the
Company Current Financial Statements; and (ii) owns such rights, interests,
assets and property free and clear of all Encumbrances, title defects or
objections (except for taxes not yet due and payable).  The personal property

to continue operation of the Company and any Company Subsidiary.

         Section 3.16     Indebtedness for Borrowed Money.  Except for trade
payables incurred in the ordinary course of business, the Company does not have

any manner (actual or contingent) to assume or guarantee any indebtedness or

future payments of $10,000 in any fiscal year or $25,000 in the aggregate

identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
prior to the Spin-Off Transaction, all agreements between the Company, on the

payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,

amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all

person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000
in any fiscal year or $25,000 in the aggregate and that are not cancelable by
providing notice of sixty (60) days or less.  All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is

binding in accordance with their terms after consummation of the transaction
contemplated

herein; there are no contracts, agreements or other instruments to which the
Company is a party or is bound (other than physician employment contracts and
insurance policies) which could either singularly or in the aggregate have a
Material Adverse Effect on the value to APP of the assets and properties to be
acquired by APP from the Company, or which could inhibit or prevent the Company
from transferring to or vesting in APP good and sufficient title to the assets
and properties to be acquired by APP and the Surviving Corporation except where
the failure to transfer would not have a Material Adverse Effect on APP.  In
every instance where consent is necessary, the Company shall, on or before the
Closing Date, use reasonable good faith efforts to obtain and deliver to APP in
writing, effective as of the Closing Date, such consents as are necessary to
enable the Surviving Corporation to enjoy all of the rights now enjoyed by the
Company under such contracts.  Any and all such consents shall be in a form
reasonably acceptable to APP and shall contain an acknowledgment by the
consenting party that the Company has fully complied with and is not in default
under any provision of the particular contract or agreement.  Notwithstanding
the foregoing, the Company shall not transfer to APP any contracts or
agreements relating to the provision of professional medical services or other
such agreements and contracts that APP consents to in writing to be transferred
to NewCo in the Spin-off Transaction.  No contract with a health care provider

or intention of any other party to exercise any right to cancel or terminate
any contract, agreement or instrument required to be disclosed pursuant to
Section 3.17(a), and to the knowledge of the Company there are no fact(s) that
would justify the exercise of such a right; and (ii) does not currently
contemplate, or have reason to believe any other Person currently contemplates,
any amendment or change to any such contract, agreement or instrument.

         Section 3.18     Employee Matters.  The Company is not currently a
party to any employment contract (except for oral employment agreements which

compensation commitments, benefit plans, arrangements or plans (whether written
or oral), including all welfare plans (as defined in Section 3(1) of ERISA) of

predecessors in interest.  As of April 30, 1997, the Company employed a
collective total of [___] part-time and [____] full-time employees.  The

Employment Opportunity Commission or any federal, state or local agency or

Employee Benefit Plans can be terminated or amended at will by the Company

further contributions or payments in connection therewith following such
termination.  No unwritten amendment exists with respect to any Employee
Benefit Plan.

                 (b)      Administration.  Each Employee Benefit Plan has been
administered and maintained in compliance with all applicable laws, rules and

reasonably likely to result, directly or indirectly, (including through any
obligation of indemnification or contribution), in any taxes, penalties or
other liability to APP or any of its Affiliates.

                 (e)      Claims and Litigation.  No pending or, to the

member of a controlled group (within the meaning of Section 412(n)(6)(B) of the
Code) in which the Company is a member (a "Controlled Group").  With respect to
each Employee Benefit Plan subject to Title IV of ERISA, the assets of each
such plan are at least equal in value to the present value of accrued benefits
determined on an ongoing basis as of the date hereof.  With respect to each
Employee Benefit Plan described in Section 501(c)(9) of the Code, the assets of
each such plan are at least equal in value to the present value of accrued
benefits, based upon the most recent actuarial valuation as of a date no more
than ninety (90) days prior to the date hereof.  The Disclosure Schedules

to determine the present value of accrued benefits under all Employee Benefit
Plans subject to actuarial assumptions.

412 of the Code.

                 (j)      PBGC.  No facts or circumstances are known to the
Company that would result in the imposition of liability against APP, or any of
its Affiliates by the Pension Benefit Guaranty Corporation ("PBGC") as a result
of any act or omission by the Company or any member of a Controlled Group.  No
reportable event (within the meaning of Section 4043 of ERISA) for which the
notice requirement has not been waived has occurred with respect to any
Employee Benefit Plan subject to the requirements of Title IV of ERISA.

                 (k)      Retirees.  The Company has no obligation or
commitment to provide medical, dental or life insurance benefits to or on
behalf of any of its employees who may retire or any of its former employees
who have retired except as may be required pursuant to the continuation of
coverage provisions of Section 4980B of the Code and the applicable provisions
of ERISA.

                 (l)      Other Compensation Arrangements.  Neither the Company
nor, to the Company's knowledge, any Stockholder or Physician Employee is a

filings of any kind or nature necessary to be filed by the Company with any
governmental agency or authority have been properly completed and timely filed
in compliance with all applicable requirements, except where failure to so file

         Section 3.23     Insurance Policies.  The Disclosure Schedules list
and briefly describe the Company's policies of insurance to which the Company
or any Company Subsidiary is a party or under which the Company or any Company
Subsidiary, officer or director thereof is or has been covered at any time
during the last five (5) years preceding the date of this Agreement relating to
the business of the Company or any Company Subsidiary (the "Insurance
Policies").  All of the Insurance Policies are valid, outstanding and
enforceable policies, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies and all premiums with respect thereto which
are due and payable are currently paid.  All Insurance Policies currently
maintained by the Company or any Company Subsidiary ("Current Policies") taken
together, (i) provide adequate insurance coverage for the assets, properties
and operations of the Company and its Affiliates for all risks normally insured
against by a Person carrying on a substantially similar business or businesses

legal and contractual requirements to which the Company or any of its
Affiliates is a party or by which any of them may be bound, and (iii) shall be
maintained in force (including the payment of all premiums and compliance with
their terms) without interruption up to and including the Closing Date.  True,
complete and correct copies of all Insurance Policies have been provided to
APP.  Neither the Company nor any Company Subsidiary nor any officer or
director thereof has received any notice or other written communication from
any issuer of any Current Policy cancelling such policy, materially increasing
any deductibles or retained amounts thereunder, or materially increasing the
annual or other premiums payable thereunder and, to the knowledge of the
Company, no such cancellation or increase of deductibles, retainages or
premiums is threatened.  There are no outstanding claims, settlements or
premiums owed against any Insurance Policy, and all required notices have been
given and all known potential or actual claims under any Insurance Policy have
been presented in due and timely fashion.  Within the five (5) years preceding
the Agreement, neither the Company nor any Company Subsidiary has filed a
written application for any professional liability insurance coverage which has
been denied by an insurance agency or carrier.  The Disclosure Schedules also
set forth a list of all claims under any Insurance Policy in excess of $10,000
per occurrence filed by the Company or any Company Subsidiary during the
immediately preceding three-year period.  Each Physician Employee has, at all
times while a Physician Employee, maintained or been covered by professional

         Section 3.24     Accounts Receivable; Payors.

                 (a)      The Disclosure Schedules set forth a list and aging
of all accounts receivable of the Company as of March 31, 1997, which list is

previously written off as bad debts and, are, to the extent still uncollected,
to the knowledge of the Company collectible in the ordinary course of business,
net of reserves for doubtful and uncollectible accounts shown in the Company

reserves are calculated consistent with generally accepted accounting
principles and past practice).

                 (b)      The Disclosure Schedules set forth (i) a true,
correct and complete list of the names and addresses of each Payor of the
Company as of such date, which accounted for more than 5% of the revenues of
the Company in the fiscal year ended December 31, 1996, or which is reasonably
expected to account for more than 5% of the revenues of the Company for the
fiscal year to end December 31, 1997, and (ii) a single line item listing for
all private-pay patients in the aggregate of the Company.  The Company has
satisfactory relations with such Payors set forth in (i) above and none of such
Payors has notified the Company that it intends to discontinue its relationship
with the Company or to deny any payments due from, or any claims for payment
submitted to any such party.

fiscal year ended December 31, 1996, or which is reasonably expected to account
for a dollar volume of purchases paid for by the Company in excess of $25,000
for the fiscal year to end December 31, 1997.

items on hand at the Effective Time will consist, net of all applicable
reserves with respect thereto (calculated consistent with past practice), of
items of a quality and a quantity usable and saleable in the ordinary course of
the Company's business and conform to generally accepted standards in the
industry of which the Company is a part.  The value of the inventories
reflected on the Company Current Balance Sheet contained in the Company
Financial Statements are net of adequate reserves for damaged, excess, and
unusable items.  Purchase commitments of the Company for inventory are not
materially in excess of normal requirements, and none of such purchase
commitments are at prices in excess of prevailing market prices at the time of
such purchase commitment.

         Section 3.27     Licenses, Authorization and Provider Programs.

Employee has a current provider number for such Governmental Programs and with
such private non-governmental programs (including without limitation any
private insurance program) under which the Company is presently receiving
payments directly or indirectly from any Payor for patient care provided by
such Physician Employee, licensed employee or independent contractor (such

numbers and participating physician contracts under 1842(h) of the Social
Security Act), and provider agreements, is set forth in the Disclosure
Schedules, true, complete and correct copies of which have been provided to
APP.  No violation, default, order or deficiency exists with respect to any of
the items listed in the Disclosure Schedules except for such violations,
defaults, orders or deficiencies which would not be reasonably likely to have a
Material Adverse Effect on the Company, and there is no action pending or to
the Company's knowledge recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program,

the Company, or any Physician Employee, nor the right of any licensed
professional or other individual affiliated with the Company to receive
reimbursements pursuant to any Governmental Program or Private Program has been
terminated or otherwise materially and adversely affected as a result of any
investigation or action whether by any federal or state governmental regulatory
authority or other third party.  No Physician Employee, licensed professional
or other individual affiliated with the business has, during the past three (3)
years prior to the Effective Time, had their professional license or staff
privileges limited, suspended or revoked by any governmental regulatory
authority or agency, hospital, integrated delivery system, trade association,
professional review organization, accrediting organization or certifying agency

filings or notifications required to be made or obtained solely by the Company,
the execution, delivery and performance by APP of this Agreement and the
agreements provided for herein, and the consummation of the Merger and the
transactions contemplated hereby and thereby by APP requires no action by or in
respect of, or filing with, any governmental body, agency, official or
authority.

         Section 4.4      Capitalization.  The authorized capital stock of APP
consists of 20,000,000 shares of APP Common Stock, of which 2,000,000 shares
are issued and outstanding and 10,000,000 shares of APP Preferred Stock, none
of which are outstanding.  Each outstanding share of APP Common Stock has been
legally and validly issued and is fully paid and nonassessable, and was issued
pursuant to a valid exemption from registration under (i) the Securities Act of
1933, as amended, and (ii) all applicable state securities laws.  No shares of
capital stock are owned by APP in treasury.  No shares of capital stock of APP
have been issued or disposed of in violation of the preemptive rights, rights
of first refusal or similar rights of any stockholders of APP.  APP has no
bonds, debentures, notes or other obligations the holders of which have the
right to vote (or are convertible into or exercisable for securities having the
right to vote) with the stockholders of APP on any matter.  There exist no
options, warrants, subscriptions, calls, commitments or other rights to
purchase, or securities convertible into or exchangeable for, any of the
authorized or outstanding securities of APP and no option, warrant,
subscription, call, or commitment or commission right of any kind exists which
obligates APP to issue any of its authorized but unissued capital stock.  APP
has no obligation (contingent or otherwise) to purchase, redeem or otherwise
acquire any of its equity securities or any interests therein or to pay any
dividend or make any distribution in respect thereof.

         Section 4.5      Subsidiaries and Investments.  APP does not own,
directly or indirectly, any capital stock or other equity, ownership or
proprietary interest in any corporation, partnership, association, trust, joint
venture or other entity (the "APP Subsidiaries").

         Section 4.6      Absence of Conflicting Agreements or Required
Consents.  The execution, delivery and performance of this Agreement by APP and
any other documents contemplated hereby (with or without the giving of notice,
the lapse of time, or both): (i) does not require the consent of any
governmental or regulatory body or authority or any other third party except
for such consents, for which the failure to obtain would not result in a
Material Adverse Effect on APP; (ii) will not conflict with any provision of
APP's certificate of incorporation or bylaws; (iii) will not conflict with,
result in a violation of, or constitute a default under any law, ordinance,
regulation, ruling, judgment, order or injunction of any court or governmental
instrumentality to which APP is a party or by which APP or its properties are
subject or bound; (iv) will not conflict with, constitute grounds for
termination of, result in a breach of, constitute a default under, require any
notice under, or accelerate or permit the acceleration of any performance
required by the terms of any agreement, instrument, license or permit, material

properties are bound except for such conflict, termination, breach or default,
the occurrence of which would not result in a Material Adverse Effect on APP;
and (v) will not create any Encumbrance or restriction upon APP Common Stock or
any of the assets or properties of APP.  The financial statements of APP
contained in the Registration Statements (a) have been prepared in accordance
with generally accepted accounting principles consistently applied (except as
may be indicated therein or in the notes thereto), (b) present fairly the
financial position of APP and APP Subsidiaries as of the dates indicated and
present fairly the results of APP's and APP Subsidiaries' operations for the

correct in all material respects.

liabilities, reserves, business or operations of APP that has had or is

order, injunction or decree, or any other requirement of any governmental body,

S-4, APP does not have any material arrangements, agreements or plans with any
person with respect to the employment by APP of such person or whereby such

Returns or reports are complete and accurate in all material respects and
properly reflect the taxes of APP for the periods covered thereby.

Tax Returns that it has filed and has properly accrued on its books and records

knowledge of APP, threatened bankruptcy, insolvency or similar proceeding with
respect to any other party to such agreements, and no event has occurred which

party thereto.

                                   ARTICLE V

           Closing Date Representations and Warranties of the Company

         The Company represents and warrants that the following will be true
and correct on the Closing Date as if made on that date:

         Section 5.1      Organization and Good Standing; Qualification.  NewCo
is a professional association duly organized, validly existing and in good
standing under the laws of its state of organization, with all requisite
corporate power and authority to carry on the business in which it intends to
engage, to own the properties it intends to own, and to execute and deliver the
Service Agreement, the Security Agreement and the Physician Employment
Agreements and consummate the transactions and perform the services
contemplated thereby.  NewCo is duly qualified and licensed to do business and
is in good standing in all jurisdictions where the nature of its intended
business makes such qualification necessary, which jurisdictions are listed in
the Disclosure Schedules, except where the failure to be so qualified shall not
have a Material Adverse Effect on NewCo.

         Section 5.2      Capitalization.  The authorized capital stock of
NewCo consists of [_____] shares of NewCo Common Stock, of which [______]
shares are issued and outstanding, and no shares of capital stock of NewCo are
held in treasury.  The Stockholders own all of the issued and outstanding
shares of NewCo Common Stock, free and clear of any Encumbrance.  Each
outstanding share of NewCo Common Stock has been legally and validly issued and
is fully paid and nonassessable.  There exist no options, warrants,
subscriptions or other rights to purchase, or securities convertible into or
exchangeable for, any of the authorized or outstanding securities of NewCo.  No
shares of capital stock of NewCo have been issued or disposed of in violation
of the preemptive rights, rights of first refusal or similar rights of any of
NewCo's stockholders.

         Section 5.3      Corporate Records.  The copies of the articles or
certificate of incorporation and bylaws, and all amendments thereto, of NewCo
that have been delivered or made available to APP are true, correct and
complete copies thereof, as in effect on the Closing Date.

         Section 5.4      Authorization and Validity.  The execution, delivery
and performance by NewCo of the Service Agreement, the Security Agreement, the
Physician Employment Agreements and the other agreements contemplated thereby,
and the consummation of the transactions and provision of services contemplated
thereby, have been duly authorized by the Board of Directors of NewCo.  The
Service Agreement, the Security Agreement, the Physician Employment Agreements
and each other agreement contemplated thereby will be as of the Closing Date
duly executed and delivered by NewCo and will constitute valid and binding
obligations of NewCo enforceable against NewCo in accordance with their
respective terms, except as may be limited by applicable bankruptcy, or other
laws affecting creditors' rights generally, or by general equity principles, or
by public policy.

         Section 5.5      No Violation.  Neither the execution, delivery or
performance of the Service Agreement, the Security Agreement, the Physician
Employment Agreements or the other agreements contemplated thereby nor the
consummation of the transactions or provision of services contemplated thereby
will (a) conflict with, or result in a violation or breach of the terms,
conditions or provisions of, or constitute a default under, the articles or
certificate of incorporation or bylaws of NewCo, or (b) violate or conflict
with any applicable local, state or federal law, ordinance, regulation, order,
injunction or

                                       26

decree, or any other requirement of any governmental body, agency or authority
or court binding on it, or relating to its property or business.

         Section 5.6      No Business, Agreements, Assets or Liabilities.
NewCo has not commenced business since its incorporation.  Other than its
articles or certificate of incorporation and bylaws, and as of the Closing
Date, the Service Agreement, the Security Agreement, the Physician Employment
Agreements, and the other contracts and agreements assigned to NewCo as part of
the Spin-Off Transaction, NewCo is not a party to or subject to any agreement,
indenture or other instrument.  NewCo does not own any assets (tangible or
intangible) other than the consideration received upon the issuance of shares
of its capital stock or pursuant to the Spin-Off Transaction, and NewCo does
not have any liabilities, accrued, contingent or otherwise (known or unknown
and asserted or unasserted) other than those assumed pursuant to the Spin-Off
Transaction.

         Section 5.7      Compliance with Laws.  NewCo has complied with all
applicable laws, regulations and licensing requirements and has filed with the
proper authorities all necessary statements and reports, except where failure
to so comply or file would not, individually or in the aggregate, have a
Material Adverse Effect on NewCo.

best efforts to obtain the unanimous approval of its Stockholders to the
Merger.  In seeking the approval of its Stockholders, the Company shall provide
each Stockholder with the Form S-4 which shall include information as may be

require the Company to make any expenditures that are not expressly set forth

pay for or fund completely any accrued benefits, where applicable, or vested
accrued benefits for which the Company or any entity might have any liability
whatsoever arising from any tax-qualified plan as required under applicable
law.  The Company acknowledges that the purpose and intent of this covenant is
to assure that APP shall have no liability whatsoever at any time after the
Closing Date with respect to any such tax-qualified plan, unless such plan is
merged with a plan sponsored by APP.

         Section 7.11     Accounting and Tax Matters.  The Company will not
change in any material respect the accounting methods or practices followed by
the Company (including any material change in any assumption underlying, or any
method of calculating, any bad debt, contingency or other reserve), except as
may be required by generally accepted accounting principles.  The Company will

interest in and to the Employee Benefit Plans, all contracts and agreements and
other assets listed on the Disclosure Schedules (to be delivered by the Company
prior to Closing, which schedule will be subject to the approval of APP, which
approval shall not be unreasonably withheld) which by law either cannot be
acquired or cannot be used by APP because they relate to the practice of
medicine or radiology, and shall contribute to NewCo such other consideration
and assets of the Company as may be required under applicable law, in exchange
for the issuance by NewCo of shares of NewCo Common Stock, such shares being
all of the issued and outstanding shares of NewCo Common Stock.  The Company
shall then distribute the shares of NewCo Common Stock to the Stockholders in
proportion to their respective ownership interest in the Company.

and, at the Company's sole expense, make copies of all documents, records and
information with respect to the affairs of APP as the Company and its
representatives may reasonably request, all for the sole purpose of permitting
the Company to become familiar with the business and assets and liabilities of

otherwise affect any of the representations, warranties, covenants or
agreements of APP under this Agreement.

         Section 8.4      Notification of Certain Matters.  APP shall promptly
inform the Company in writing of (a) any notice of, or other communication
relating to, a default or event that, with notice or lapse of time or both,

the Code) to the benefits provided under the qualified plans referenced in the
Disclosure Schedules, if any, sponsored by the Company as of March 31, 1997.
APP will file for a favorable determination letter from the IRS on the New
Qualified Plan and request a favorable determination from the IRS that NewCo is
not a member of an affiliated service group (as defined in Section 414(m) of
the Code) or a recipient organization of leased employee services (as defined
in Section 414(n) of the Code).  Any benefits provided under the New Qualified
Plan shall be conditioned on a favorable determination letter from the IRS.
Costs associated with the establishment and design of the New Qualified Plan
shall be paid by APP.  NewCo shall be responsible for funding any contributions
to, or any ongoing administrative costs of, the New Qualified Plan.

other appropriate Forms) to be filed by APP in connection with its Initial
Public Offering and offering of the shares of APP Common Stock to the Target

         (b)     The Company and APP each separately represent and warrant that
(i) in the case of the Company, none of the written information or documents
supplied or to be supplied by it specifically for inclusion in the Registration
Statements, by exhibit or otherwise and (ii) in the case of APP will, at the
time the Registration Statements and each amendment and supplement thereto, if
any, becomes effective under the Securities Act, none of them contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading.  The Company

obligation until the Closing to supplement or amend promptly the Disclosure
Schedules with respect to any matter that would have been or would be required
to be set forth or described in the Disclosure Schedules in order to not
materially breach any representation, warranty or covenant of such party

Schedule that constitutes or reflects a Material Adverse Effect on the Company
may be made unless APP consents to such amendment or supplement, and no
amendment or supplement to a Schedule that constitutes or reflects a Material
Adverse Effect on APP may be made unless the Company consents to such amendment

consultation, although the foregoing shall not apply to any disclosure by APP
in any filing with the DOJ, FTC or SEC.

         Section 9.5      Expenses.  Each party to this Agreement shall be
solely responsible for their own fees and expenses with respect to the
transactions contemplated herein including, without limitation, the fees
charged by attorneys, accountants and financial advisors retained by such
parties.  The fees and expenses incurred by the Company and NewCo in connection
with the Merger shall be paid by the Company in full immediately prior to the
Closing and such expenses shall be the sole responsibility of the Stockholders
following the Closing Date and not APP.

         Section 9.6      Patient Confidentiality.  APP shall agree to keep all
records and information regarding the patients of the Company and NewCo
confidential in accordance with all applicable laws.

                 (k)      such other instrument or instruments of transfer
prepared by the Company as shall be necessary or appropriate, as the Company or

                                  ARTICLE XIII

                              Post Closing Matters

         Section 13.1     Further Instruments of Transfer.  Following the
Closing, at the request of APP or the Surviving Corporation and at APP's sole
cost and expense, the Stockholders and the Company shall deliver any further
instruments of transfer and take all reasonable action as may be necessary or
appropriate to carry out the purpose and intent of this Agreement.  Following
the Closing, at the request of NewCo and at NewCo's sole cost and expense, APP
or the Surviving Corporation shall deliver any further instruments of transfer
and take all reasonable action as may be necessary and appropriate to carry out
the purpose and intent of this Agreement.

         Section 13.2     Merger Tax Covenant.

         (a)     The parties intend that the Merger will qualify as a tax-free
transaction under Section 351 of the Code in which the Company will not
recognize gain or loss, and pursuant to which any gain recognized by a
Stockholder as a result of the Merger will not exceed the amount of any cash
received by a Stockholder in the Merger (a "Reorganization").

         (b)     Both prior to and after the Effective Time, all books and
records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Merger being treated as a Reorganization.
These obligations are excused as to a party required to maintain the books or
file a Tax Return if such party has provided to the other parties a written
opinion of competent tax counsel to the effect that there is not substantial
authority, within the meaning of Section 6662(d)(2)(B)(i) of the Code, to
report the Merger as a Reorganization and such opinion either is furnished
prior to the Effective Time or is based on facts or events not known at the
Effective Time.  Each party shall provide to each other party such tax
information, reports, returns, or schedules as may be reasonably required to
assist such party in accounting for and reporting the Merger as a
Reorganization.

         (c)     The parties agree that no Stockholder shall be liable for any
taxes incurred by the Company and for which APP has successor liability
therefor which arise solely as a result of the Merger or the consummation of
the transactions contemplated hereby; provided that the foregoing shall not
limit or otherwise be deemed a waiver of any right of indemnification under
Section 14.1 for a breach of any representation, warranty or covenant of the
Company or any Stockholder.

         Section 13.3     Current Public Information.  APP shall cause the
requirements of Rule 144(c) under the Securities Act to be met with respect to
APP for so long as those requirements must be met to enable sales by the
Stockholders who are affiliates of the Company to meet the requirements of Rule
145(d) under the Securities Act.

                                  ARTICLE XIV

                                    Remedies

         Section 14.1     Indemnification by the Company.  Subject to the terms
and conditions of this Article XIV, the Company agrees to indemnify, defend and
hold APP and the Surviving Corporation and their respective directors,
officers, stockholders, employees, agents, attorneys, consultants and
Affiliates harmless from and against all losses, claims, obligations, demands,
assessments, penalties, liabilities, costs, damages, reasonable attorneys' fees
and expenses (including, without limitation, all costs of experts and

                                       38
<PAGE>   45

all costs incidental to or in connection with any appellate process)
(collectively, "Damages") asserted against or incurred by such individuals
and/or entities arising out of or resulting from:

                 (a)      a breach by the Company of any representation or
warranty (without giving effect to any Material Adverse Effect qualifier
contained as part of any such representation or warranty) or covenant of the
Company contained in this Agreement or in any Schedule or certificate delivered
thereunder;

                 (b)      any violation (or alleged violation) by the Company
and/or any of its past or present directors, officers, partners, stockholders,
employees (including, without limitation, any Physician Employee), agents,
attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons
in which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

                 (c)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any (i) untrue
statement of material fact in any Registration Statement or any prospectus
forming or part thereof, or any amendment thereof or supplement thereto
relating to the Company (including any Company Subsidiary) or NewCo required to
be stated therein or (ii) failure to state information necessary to make the
statements therein not misleading, which untrue statement or failure to state
information arises or results solely from information provided in writing to
APP or its counsel by the Company or any Stockholder or their agents
specifically for inclusion in any such Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto.

         Section 14.2     Indemnification by APP.  Subject to the terms and
conditions of this Article XIV, APP hereby agrees to indemnify, defend and hold
the Stockholders, the Company and NewCo and their respective directors,
officers, stockholders, employees, agents, attorneys, consultants and
Affiliates harmless from and against all Damages asserted against or incurred
by such individuals and/or entities arising out of or resulting from:

                 (a)      a breach by APP of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of APP contained in
this Agreement or in any schedule or certificate delivered hereunder; and

                 (b)      any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any untrue statements
of material fact in any Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or required to be
stated therein or failure to state information necessary to make the statements
therein not misleading (except for any liability based upon any actual or
alleged untrue statement of material fact or an omission to state a material
fact relating to NewCo, the Company or any Stockholder which was derived from
any information provided in writing by the Company or a Company Subsidiary or
any of their agents contained in the representations and warranties set forth
in this Agreement or any certificate, exhibit, schedule or instrument required
to be delivered under this Agreement.)

                 Notwithstanding anything contained in either Sections 14.1 or
14.2 herein to the contrary, nothing contained in this Agreement shall relieve
any of the parties hereto of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

         Section 14.3     Conditions of Indemnification.  All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                 (a)      Any party claiming indemnification under the
Agreement (an "Indemnified Party") shall promptly (and, in the event, at least
ten (10) days prior to the due date for any responsive pleadings, filings or
other documents) (i) notify the party for whom indemnification is sought (the
"Indemnifying Party) of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying
Party a written notice ("Claim Notice") describing in reasonable detail the
nature of the Third Party Claim, a copy of all papers served with respect to
such claim (if any), an estimate of the amount of Damages attributable to the
Third Party Claim and the basis of the Indemnified Party's request for
indemnification under this Agreement.  The failure to promptly deliver a Claim
Notice shall not relieve any Indemnifying Party of its obligations to any
Indemnified Party with respect to the related Third Party Claim except to the
extent that the resulting delay is materially prejudicial to the defense of
such claim.  Within thirty (30) days after receipt of any Claim Notice (the
"Election Period"), the Indemnifying Party shall notify the Indemnified Party
(x) whether the Indemnifying Party disputes its potential liability to the
Indemnified Party under this Article XIV with respect to such Third Party Claim
and (y) whether the Indemnifying Party desires, at the sole cost and expense of
such Indemnifying Party, to defend the Indemnified Party against such Third
Party Claim.

                 (b)      If the Indemnifying Party notifies the Indemnified
Party within the Election Period that the Indemnifying Party elects to assume
the defense of the Third Party Claim, then the Indemnifying Party shall have
the right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b).  Except as set
forth in Section 14.3(f) below, the Indemnifying Party shall have full control
of such defense and proceedings, including any compromise or settlement
thereof.  The Indemnified Party is hereby authorized, at the sole cost and
expense of the Indemnifying Party (but only if the Indemnified Party is
entitled to indemnification hereunder), to file, during the Election Period,
any motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Party and not prejudicial to the Indemnifying Party.  If requested by the
Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense
of the Indemnifying Party, to cooperate with the Indemnifying Party and their
counsel in contesting any Third Party Claim that the Indemnifying Party elects
to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person.  The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Party pursuant to this Section 14.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Party, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Party, and upon written
notification thereof, the Indemnifying Party shall not have the right to assume
the defense of such action on behalf of the Indemnified Party; provided further
that the Indemnifying Party shall not, in connection with any one such action
or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party.  Notwithstanding the foregoing, the
Indemnifying Party shall be prohibited from confessing or settling any criminal
allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                 (c)      If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 14.3(b), or

                                       40
<PAGE>   47
if the Indemnifying Party elects to defend the Indemnified Party pursuant to
Section 14.3(b) but fails diligently and promptly to prosecute or settle the
Third Party Claim, then the Indemnified Party shall have the right to defend,
at the sole cost and expense of the Indemnifying Party (if the Indemnified
Party is entitled to indemnification hereunder), the Third Party Claim by all
appropriate proceedings, which proceedings shall be promptly and vigorously
prosecuted by the Indemnified Party to a final conclusion or settled.  The
Indemnified Party shall have full control of such defense and proceedings,
provided, however, that the Indemnified Party may not enter into, without the
Indemnifying Party's consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim.  Notwithstanding the
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes their
potential liability to the Indemnified Party under this Article XIV and if such
dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party
shall not be required to bear the costs and expenses of the Indemnified Party's
defense pursuant to this Section or of the Indemnifying Party's participation
therein at the Indemnified Party's request, and the Indemnified Party shall
reimburse the Indemnifying Party in full for all costs and expenses of such
litigation.  The Indemnifying Party may participate in, but not control, any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 14.3(c), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnifying Party
has been advised by counsel that there may be one or more legal defenses
available to it that are different from or additional to those available to the
Indemnified Party, then the Indemnifying Party may employ separate counsel and
upon written notification thereof, the Indemnified Party shall not have the
right to assume the defense of such action on behalf of the Indemnifying Party.

                 (d)      In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification
under this Agreement.  If the Indemnifying Party does not notify the
Indemnified Party within sixty (60) days from its receipt of the Indemnity
Notice that the Indemnifying Party disputes such claim, the claim specified by
the Indemnified Party in the Indemnity Notice shall be deemed a liability of
the Indemnifying Party hereunder.  If the Indemnifying Party has timely
disputed such claim, as provided above, such dispute shall be resolved by
litigation in an appropriate court of competent jurisdiction if the parties do
not reach a settlement of such dispute within thirty (30) days after notice of
a dispute is given.

                 (e)      Payments of all amounts owing by any Indemnifying
Party pursuant to this Article XIV relating to a Third Party Claim shall be
made within thirty (30) days after the latest of (i) the settlement of such
Third Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.  Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice
period or (ii) the expiration of the period for appeal of a final adjudication
of the Indemnifying Party's liability to the Indemnified Party under this
Agreement.

                 (f)      The Indemnifying Party shall provide the Indemnified
Party with written notice of any firm offer that is made to settle or
compromise a Third Party Claim against an Indemnified Party.  If a firm offer
is made to settle such a claim solely by the payment of money damages and the
Indemnifying Party notifies the Indemnified Party in writing that the
Indemnifying Party agrees to such settlement, but the Indemnified Party elects
not to accept and agree to it, the Indemnified Party may continue to contest or
defend such Third Party Claim and, in such event, the total maximum liability
of the Indemnifying Party to indemnify or otherwise reimburse the Indemnified
Party hereunder with respect to such a claim shall be limited to and shall not
exceed the amount of such settlement offer, plus reasonable out-of-pocket costs

                                       41
<PAGE>   48
and reasonable expenses (including reasonable attorneys' fees and
disbursements) to the date of notice that the Indemnifying Party desired to
accept such settlement.

                 (g)      Notwithstanding any provision herein to the contrary,
the obligation of an Indemnifying Party to provide indemnification to an
Indemnified Party for breach of any representation or warranty as provided in
Sections 14.1(a) or 14.2(a) hereof shall not take effect unless and until the
Damages asserted against or incurred in the aggregate and on a collective basis
by the Indemnified Parties pursuant to either Section 14.1 or 14.2 (as
applicable) as a result of such a breach or breaches exceeds $100,000.

         Section 14.4     Costs, Expenses and Legal Fees.  Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 14.5     Tax Benefits; Insurance Proceeds.  The total amount
of any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

                                   ARTICLE XV

                                  Termination

         Section 15.1     Termination.  This Agreement may be terminated and
the Merger and the Acquisitions may be abandoned:

                 (a)      at any time prior to the Effective Date by mutual
agreement of all parties;

                 (b)      at any time prior to the Effective Date by APP if any
material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and
delivered by the Company or any Stockholder pursuant to this Agreement is or
becomes untrue or breached in any material respect or if the Company or any
Stockholder fails to comply in any material respect with any material covenant
or agreement contained herein, and any such misrepresentation, noncompliance or
breach is not cured, waived or eliminated within thirty (30) days after receipt
of written notice thereof;

                 (c)      at any time prior to the Effective Date by the
Company if any representation or warranty of APP contained in this Agreement or
in any certificate or other document executed and delivered by APP pursuant to
this Agreement is or becomes untrue in any material respect of if APP fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

                 (d)      at any time prior to the Effective Date by APP if, as
a result of the conduct of due diligence and regulatory compliance procedures,
APP deems termination to be advisable; or

                 (e)      by APP or the Company if the Merger shall not have 
been consummated by September 30, 1997.

         Section 15.2     Effect of Termination.  Except as set forth in
Section 16.3, in the event this Agreement is terminated pursuant to this
Article XV, this Agreement shall forthwith become void.

                                  ARTICLE XVI

                   Nondisclosure of Confidential Information

         Section 16.1     Non-Disclosure Covenant.  The Company and NewCo
recognize and acknowledge that each has in the past, currently has, and in the
future may possibly have, access to certain Confidential Information of APP and
the Surviving Corporation that is valuable, special and a unique asset of such
entity's business.  APP acknowledges that it had in the past, currently has,
and in the future may possibly have, access to certain Confidential Information
of the Company and NewCo that is valuable, special and a unique asset of each
such business.  The Company, NewCo and APP, severally, agree that they will not
disclose such Confidential Information to any person, firm, corporation,
association or other entity for any purpose or reason whatsoever, except (a) to
authorized representatives of APP, NewCo and the Company and (b) to counsel and
other advisers to APP, NewCo and the Company provided that such advisers (other
than counsel) agree to the confidentiality provisions of this Section 16.1,
unless (i) such information becomes available to or known by the public
generally through no fault of the Company, NewCo or APP, as the case may be,
(ii) disclosure is required by law or the order of any governmental authority
under color of law, provided, that prior to disclosing any information pursuant
to this clause (ii) the Company, NewCo or APP, as the case may be, shall, if
possible, give prior written notice thereof to the Company, NewCo or APP and
provide the Company or APP with the opportunity to contest such disclosure,
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, or
(iv) the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Merger or otherwise.  In the event of a breach
or threatened breach by the Company, on the one hand, and APP, on the other
hand, of the provisions of this Section, APP, NewCo and the Company shall be
entitled to an injunction restraining the other party, as the case may be, from
disclosing, in whole or in part, such Confidential Information.  Nothing herein
shall be construed as prohibiting any of such parties from pursuing any other
available remedy for such breach or threatened breach, including the recovery
of damages.

         Section 16.2     Damages.  Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, NewCo and the Company agree
that, in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

         Section 16.3     Survival.  The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVII

                                 Miscellaneous

         Section 17.1     Amendment; Waivers.  This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto.  Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto.  The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 17.2     Assignment.  Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any party hereto,
except by APP to a wholly owned subsidiary of APP; provided that any such
assignment shall not relieve APP of its obligations hereunder.

         Section 17.3     Parties in Interest; No Third Party Beneficiaries.
Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the

                                       43
<PAGE>   50
respective heirs, legal representatives, successors and assigns of the parties
hereto.  APP acknowledges and agrees that the rights and remedies of the
Company under this Agreement will be directly available to the Stockholders as
third party beneficiaries of the rights and remedies of the Company under this
Agreement, including, without limitation, the rights and remedies under Article
14 hereof to indemnification from APP against Damages incurred by the
Stockholders resulting from a breach by APP of any representation, warranty or
covenant of APP contained herein.  Except as provided in the preceding sentence
or as otherwise provided herein, neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party
hereto or thereto any rights or remedies hereunder or thereunder.

         Section 17.4     Entire Agreement.  This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding
the subject matter hereof, and supersede all prior agreements and
understandings, both written and oral, among the parties, or any of them, with
respect to the subject matter hereof.

         Section 17.5     Severability.  If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining

indemnity) receive such allocation of Merger Consideration as determined in
accordance with the provisions of Exhibit B attached hereto; and (ii) until each

surrendered by the Stockholders, the certificates for Company Common Stock
shall, for all purposes, represent solely the right to receive Merger
Consideration as determined in accordance with the provisions of Exhibit B
attached hereto and Section 2.8 hereof, if applicable. At the Effective Time,
each share of Company Common Stock converted into Merger Consideration shall by
virtue of the Merger and without any action on the part of the holders thereof,
cease to be outstanding, be cancelled and returned and all shares of APP Common
Stock issuable to the Stockholders in the Merger as part of the Merger

certificates representing Company Common Stock owned by him, her or it, duly
endorsed in blank by the Stockholder, or accompanied by duly executed stock
powers in blank, and with all necessary transfer tax and other revenue stamps,
acquired at the Stockholder's expense, affixed and cancelled. Each Stockholder
agrees to cure any deficiencies with respect to the endorsement of the
certificates or other documents of conveyance with respect to such Company
Common Stock or with respect to the stock powers accompanying any Company Common
Stock. Upon such delivery (or completion of appropriate affidavit of lost
certificate and indemnity), each Stockholder shall receive in exchange therefor
the Merger Consideration pursuant to Exhibit B and Section 2.8 hereof, if
applicable.

      Section 2.8 Fractional Shares. Notwithstanding any other provision herein,
no fractional shares of APP Common Stock will be issued and any Stockholder
otherwise entitled to receive a fractional share of APP Common Stock as part of
the Merger Consideration hereunder shall receive a cash payment in lieu thereof
reflecting such Stockholder's proportionate interest in a share of APP Common
Stock multiplied by the Initial Public Offering Price.

if any, set forth in this Section 3.12 is fully covered by policies of insurance
of the Company or any Company Subsidiary as in effect on the date hereof.

      Section 3.13 No Violation of Law. Neither the Company nor any Company
Subsidiary has been, nor shall be as of the Effective Time (by virtue of any
action, omission to act, contract to which it is a party or any occurrence or
state of facts whatsoever), in violation of any applicable local, state or
federal law, ordinance, regulation, order, injunction or decree, or any other
requirement of any governmental body, agency, authority or court binding on it,
or relating to its properties, assets or business or its advertising, sales or
pricing practices, except for violations which, individually or in the

the Company.

      Section 3.14 Lease Agreements. The Disclosure Schedules contain a true,
accurate and complete list of all the lease agreements and license agreements to
which the Company or any Company Subsidiary is a party and pursuant to which the
Company or any Company Subsidiary leases (whether as lessor or lessee) or
licenses (whether as licensor or licensee) any real or personal property related
to the operation of its business and which requires payments in excess of
$12,000 per year (the "Lease Agreements"). The Company has delivered to APP true
and complete copies of all of the Lease Agreements. Each Lease Agreement is
valid, effective and in full force in accordance with its terms, and there is
not under any such lease (i) any existing or claimed material default by the
Company or any Company Subsidiary (as applicable) or event of material default
or event which with notice or lapse of time, or both, would constitute a
material default by the Company or any Company Subsidiary (as applicable) and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Company, or, (ii) to the knowledge of the Company, any existing
material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party. To the knowledge of the
Company, there is no pending or threatened reassessment of any property covered
by the Lease Agreements. The Company or any Company Subsidiary will use
reasonable good faith efforts to obtain, prior to the Effective Time, the
consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver to
APP in writing such consents as are necessary to effect a valid and binding
transfer or assignment of the Company's or any Company Subsidiary's rights
thereunder. The Company has a good, clear, valid and enforceable leasehold
interest under each of the Lease Agreements. The Lease Agreements comply with
the exceptions to ownership interests and compensation arrangements set out in
42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952, and any similar applicable
state law safe harbor or other exemption provisions.

      Section 3.15 Real and Personal Property.

interest (other than the Lease Agreements) in real property.

all of its properties and assets (real, personal and mixed, tangible and
intangible) and any rights or interests therein which it purports to own
including, without limitation, all the property and assets reflected in the
Company Current Financial Statements; and (ii) owns such rights, interests,
assets and property free and clear of all Encumbrances, title defects or
objections (except for taxes not yet due and payable). The personal property
presently used in connection with the operation of the business of the Company
and the Company Subsidiaries constitutes the necessary personal property assets
to continue operation of the Company and any Company Subsidiary.

      Section 3.16 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, the Company does not have any
direct or indirect indebtedness for borrowed money, including indebtedness by
way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

               (a) The Disclosure Schedules contain a true, accurate and
complete list, and the Company has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring the Company to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.23 or Lease Agreements
identified in Section 3.14) to which the Company is a party or by which it or
any of its properties or assets are bound including, without limitation, (i) all
agreements between the Company, on the one hand, and any Payor, government

organization or other third-party provider, on the other hand, then in effect
relating to the provision of medical, diagnostic imaging or consulting services,
treatments, patient referrals or other similar activities, (ii) all indentures,
mortgages, notes, loan or credit agreements and other agreements and obligations
relating to the borrowing of money or to the direct or indirect guarantee or
assumption of obligations of third parties requiring the Company to make, or
setting forth conditions under which the Company would be required to make,
aggregate future payments in excess of $10,000 in any fiscal year or $25,000 in
the aggregate, (iii) all agreements for capital improvements or acquisitions
involving an amount of $75,000 in any fiscal year or $75,000 in the aggregate,
(iv) all agreements containing a covenant limiting the freedom of the Company
(or any provider employee of the Company) to compete in any line of business
with any person or entity or in any geographic area or (v) all written contracts
and commitments providing for future payments by the Company in excess of
$10,000 in any fiscal year or $25,000 in the aggregate and that are not
cancelable by providing notice of sixty (60) days or less. All such contracts,
agreements or other instruments are in full force and effect, there has been no
threatened cancellation thereof, there are no outstanding disputes thereunder,
each is with unrelated third parties and was entered into on an arms-length
basis and, assuming the receipt of the appropriate consents, all will continue
to be binding in accordance with their terms after consummation of the
transaction contemplated herein; there are no contracts, agreements or other
instruments to which the Company is a party or is bound (other than physician
employment contracts and insurance policies) which could either singularly or in
the aggregate have a Material Adverse Effect on the value to APP of the assets
and properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP. In every instance where consent is necessary, the Company
shall, on or before the Closing Date, use reasonable good faith efforts to
obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts. Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. No contract with a health care provider or Payor has been materially
amended or terminated within the last twelve (12) months.

               (b) The Company (i) has not received notice of any plan or
intention of any other party to exercise any right to cancel or terminate any
contract, agreement or instrument required to be disclosed pursuant to Section
3.17(a), and to the knowledge of the Company there are no fact(s) that would
justify the exercise of such a right; and (ii) does not currently contemplate,
or have reason to believe any other Person currently contemplates, any amendment
or change to any such contract, agreement or instrument.

not currently a party to any employment contract (except for oral employment
agreements which are terminable at will), consulting or collective bargaining
contracts, deferred compensation, pension plan (as defined in Section 3(2) of
the Employee Retirement Income Security Act of 1974, as amended, and all rules
and regulations from time to time promulgated thereunder ("ERISA")), profit
sharing, bonus, stock option, stock purchase or other nonqualified benefit or

or pertaining to the Company and any of its present or former employees, or any
predecessors in interest.

Returns or reports are complete and accurate in all material respects and
properly reflect the taxes of APP for the periods covered thereby.

disputing in good faith by proceedings in compliance with applicable law, which
are described in Schedule 4.12(b), (i) APP has paid all taxes, penalties,
assessments and interest that have become due with respect to any Tax Returns
that it has filed and has properly accrued on its books and records for all of
the same that have not yet become due and (ii) APP is not delinquent in the
payment of any tax, assessment or governmental charge.

               (c) No Pending Deficiencies, Delinquencies, Assessments or
Audits. APP has not received any notice that any tax deficiency or delinquency
has been asserted against APP. There is no unpaid assessment, proposal for
additional taxes, deficiency or delinquency in the payment of any of the taxes
of APP that could be asserted by any taxing authority. There is no taxing
authority audit of APP pending, or to the knowledge of APP, threatened, and the
results of any completed audits are properly reflected in the financial
statements of APP. APP has not violated any federal, state, local or foreign tax
law.

               (d) No Extension of Limitation Period.  APP has not granted an 
extension to any taxing authority of the limitation period during which any tax
liability may be assessed or collected.

      APP and the Company agree as follows:

      Section 9.1 Filings; Other Action.

               (a) The Company shall cooperate with APP to promptly prepare and

appropriate Forms) to be filed by APP in connection with its Initial Public
Offering and offering of the shares of APP Common Stock to the Target Interest

Other Agreements (including the prospectus constituting parts thereof, the
"Registration Statements"). APP shall obtain all necessary state securities law

concerning the Company as may be reasonably requested in connection with any
such action in a timely manner.

               (b) The Company and APP each separately represent and warrant
that (i) in the case of the Company, none of the written information or
documents supplied or to be supplied by it specifically for inclusion in the
Registration Statements, by exhibit or otherwise and (ii) in the case of APP
will, at the time the Registration Statements and each amendment and supplement
thereto, if any, becomes effective under the Securities Act, none of them
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.
The Company shall be entitled to review the Registration Statements and each of
the amendments thereto, if any, prior to the time each becomes effective under
the Securities Act. The Company shall have no responsibility for information
contained in the Registration Statements except for information provided by the
Company specifically for inclusion therein. The Company's review of the

representations, covenants and warranties of APP contained in this Agreement.

               (c) The Company shall, upon request, furnish APP with all
information concerning itself, its subsidiaries, directors, officers, partners
and Stockholders, and such other matters as may be reasonably requested by APP

entity in connection with the Merger and the other transactions contemplated by
this Agreement.

Closing to supplement or amend promptly the Disclosure Schedules with respect to
any matter that would have been or would be required to be set forth or
described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on the Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Disclosure Schedule that constitutes or reflects a Material Adverse Effect on
APP may be made unless the Company consents to such amendment or supplement. For

Schedules as amended or supplemented pursuant to this Section 9.2. In the event

FTC or SEC.

responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by the Company shall be paid by the Company in full
immediately prior to the Closing and such expenses shall be the sole
responsibility of the Stockholders following the Closing Date and not APP.

      Section 9.6 Patient Confidentiality. APP shall agree to keep all records
and information regarding the patients of the Company confidential in accordance
with all applicable laws.

      Section 9.7 Registration Statements. APP shall prepare and file the

<PAGE>   38


               (a) The parties intend that the Merger will qualify as a tax-free
reorganization within the meaning of Section 351 of the Code in which the
Company will not recognize gain or loss, and pursuant to which any gain
recognized by a Stockholder as a result of the Merger will not exceed the amount
of any cash received by a Stockholder in the Merger (a "Reorganization").

               (b) Both prior to and after the Effective Time, all books and
records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Merger being treated as a Reorganization.
These obligations are excused as to a party required to maintain the books or
file a Tax Return if such party has provided to the other parties a written
opinion of competent tax counsel to the effect that there is not substantial
authority, within the meaning of Section 6662(d)(2)(B)(i) of the Code, to report
the Merger as a Reorganization and such opinion either is furnished prior to the
Effective Time or is based on facts or events not known at the Effective Time.
Each party shall provide to each other party such tax information, reports,
returns, or schedules as may be reasonably required to assist such party in
accounting for and reporting the Merger as a Reorganization.

               (c) The parties agree that no Stockholder shall be liable for any
taxes incurred by the Company and for which APP has successor liability therefor
which arise solely as a result of the Merger or the consummation of the
transactions contemplated hereby; provided that the foregoing shall not limit or
otherwise be deemed a waiver of any right of indemnification under Section 14.1
for a breach of any representation, warranty or covenant of the Company or any
Stockholder.

      Section 13.3 Current Public Information. APP shall cause the requirements
of Rule 144(c) under the Securities Act to be met with respect to APP for so
long as those requirements must be met to enable sales by the Stockholders who
are affiliates of the Company to meet the requirements of Rule 145(d) under the
Securities Act.

                                   ARTICLE XIV

                                    Remedies

      Section 14.1 Indemnification by the Company and the Stockholders. Subject
to the terms and conditions of this Article XIV, the Company and the
Stockholders agree to indemnify, defend and hold APP and the Surviving
Corporation and their respective directors, officers, stockholders, employees,
agents, attorneys, consultants and Affiliates harmless from and against all
losses, claims, obligations, demands, assessments, penalties, liabilities,
costs, damages, reasonable attorneys' fees and expenses (including, without
limitation, all costs of experts and all costs incidental to or in connection
with any appellate process) (collectively, "Damages") asserted against or
incurred by such individuals and/or entities arising out of or resulting from:

               (a) a breach by the Company or any Stockholder of any
representation or warranty (without giving effect to any Material Adverse Effect
qualifier contained as part of any such representation or warranty) or covenant
of the Company or any Stockholder contained in this Agreement or in any
Disclosure Schedule or certificate delivered thereunder;

               (b) any violation (or alleged violation) by the Company and/or
any of its past or present directors, officers, partners, Stockholders,
employees (including, without limitation, any Physician Employee), agents,
attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons in
which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and

<PAGE>   39


               (c) any liability under the Securities Act, the Exchange Act or
any other federal or state "blue sky" or securities law or regulation, at common
law or otherwise, arising out of or based upon any untrue statement of material
fact in any Registration Statement or any prospectus forming or part thereof, or
any amendment thereof or supplement thereto relating to the Company (including
any Company Subsidiary) or failure to state information necessary to make the
statements required to be stated therein not misleading arising solely from
information provided in writing to APP or its counsel by the Company or any
Stockholder or their agents specifically for inclusion in any such Registration
Statement or any prospectus forming a part thereof, or any amendment thereof or
supplement thereto.

               Notwithstanding anything herein to the contrary, nothing
contained in this Agreement shall relieve the Company of any liability or limit
any liability that it may have in the case of fraud in connection with the
transactions contemplated by this Agreement.

      Section 14.2 Indemnification by APP. Subject to the terms and conditions
of this Article XIV, APP hereby agrees to indemnify, defend and hold the
Stockholders, the Company and its directors, officers, stockholders, employees,
agents, attorneys, consultants and Affiliates harmless from and against all
Damages asserted against or incurred by such individuals and/or entities arising
out of or resulting from:

               (a) a breach by APP of any representation or warranty (without
giving effect to any Material Adverse Effect qualifier contained as part of any
such representation or warranty) or covenant of APP contained in this Agreement
or in any schedule or certificate delivered hereunder; and

               (b) any liability under the Securities Act, the Exchange Act or
any other federal or state "blue sky" or securities law or regulation, at common
law or otherwise, arising out of or based upon any untrue statements of material
fact in any Registration Statement or any prospectus forming a part thereof, or
any amendment thereof or supplement thereto, or required to be stated therein or
failure to state information necessary to make the statements therein not
misleading (except for any liability based upon any actual or alleged untrue
statement of material fact or an omission to state a material fact relating the
Company or any Stockholder which was derived from any information provided in
writing by the Company or a Company Subsidiary or any of their agents contained
in the representations and warranties set forth in this Agreement or any
certificate, exhibit, schedule or instrument required to be delivered under this
Agreement).

               Notwithstanding anything herein to the contrary, nothing
contained in this Agreement shall relieve APP of any liability or limit any
liability that it may have in the case of fraud in connection with the
transactions contemplated by this Agreement.

      Section 14.3 Conditions of Indemnification. All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

               (a) Any party claiming indemnification under the Agreement (an
"Indemnified Party") shall promptly (and, in the event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party for whom indemnification is sought (the "Indemnifying
Party) of any third-party claim or claims asserted against the Indemnified Party
("Third Party Claim") that could give rise to a right of indemnification under
this Agreement and (ii) transmit to the Indemnifying Party a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of Damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement. The failure to promptly deliver a Claim Notice shall not relieve any
Indemnifying Party of its obligations to any Indemnified Party with respect to
the related Third Party Claim except to the extent that the resulting delay is
materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (x) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article XIV
with respect to such Third Party Claim and (y) whether the Indemnifying Party

                                       34
                                     

<PAGE>   40


desires, at the sole cost and expense of such Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

               (b) If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party, such Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). Except as set forth
in Section 14.3(f) below, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof. The
Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Party (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and not
prejudicial to the Indemnifying Party. If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and their counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to this
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are
different from or additional to those available to the Indemnifying Party, then
the Indemnified Party may employ separate counsel at the expense of the
Indemnifying Party, and upon written notification thereof, the Indemnifying
Party shall not have the right to assume the defense of such action on behalf of
the Indemnified Party; provided further that the Indemnifying Party shall not,
in connection with any one such action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
more than one separate firm of attorneys at any time for the Indemnified Party,
which firm shall be designated in writing by the Indemnified Party.
Notwithstanding the foregoing, the Indemnifying Party shall be prohibited from
confessing or settling any criminal allegations brought against the Indemnified
Party without the express written consent of the Indemnified Party.

               (c) If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any 

                                       35
                                     

<PAGE>   41


such action (including any impleaded parties) include both the Indemnifying
Party and the Indemnified Party, and the Indemnifying Party has been advised by
counsel that there may be one or more legal defenses available to it that are
different from or additional to those available to the Indemnified Party, then
the Indemnifying Party may employ separate counsel and upon written notification
thereof, the Indemnified Party shall not have the right to assume the defense of
such action on behalf of the Indemnifying Party.

               (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

               (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Article XIV relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by the
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the 60-day Indemnity Notice period
or (ii) the expiration of the period for appeal of a final adjudication of the
Indemnifying Party's liability to the Indemnified Party under this Agreement.
During the two-year period following the Effective Date, each Stockholder shall
be entitled to satisfy payments owed to APP by transfer of APP Common Stock from
such Stockholder to APP. For all purposes of this Agreement, the value of each
share of APP Common Stock transferred to APP pursuant to this Agreement shall be
calculated by averaging the daily closing prices for a share of APP Common Stock
for the twenty (20) consecutive trading days on which such shares are actually
traded on the Nasdaq National Market preceding the date of the Claim Notice or
Indemnity Notice, as the case may be. The number of shares of APP Common Stock
permitted to be transferred under this Paragraph 2(e) shall be diminished
proportionately in accordance with the percentage of APP Common Stock released
under the Lock-Up Provisions set forth in Paragraph 1 of the Stockholder
Representation Letter. The rights of any Stockholder to transfer shares of APP
Common Stock in satisfaction of payments owed to APP pursuant to this Agreement
shall terminate upon the earlier of (x) the termination of the Lock-Up
Provisions set forth in the Stockholder Representation Letter or (y) at the end
of the two-year period following the Effective Date.

               (f) The Indemnifying Party shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Party notifies the Indemnified Party in writing that the Indemnifying Party
agrees to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Party to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Party desired to accept such settlement.

               (g) Notwithstanding anything contained in this Agreement or the
Merger Agreement to the contrary, the Indemnifying Parties in the aggregate (i)
shall have no obligation hereunder to provide indemnification for the first
$100,000 of Damages (without counting Immaterial Claims as defined below), 

                                       36
                                     

<PAGE>   42


and (ii) in no event shall the Indemnifying Parties have any liability hereunder
with respect to any singular incident or a fact involving a breach or inaccuracy
of the Company if the Damages from such claim are equal to or less than $7,500
("Immaterial Claims"). Notwithstanding anything to the contrary contained herein
or in the Merger Agreement, the obligations of each Stockholder hereunder shall
not exceed fifty percent (50%) of the aggregate value of the Merger
Consideration or Exchange Consideration, as the case may be, paid to such
Stockholder pursuant to any Related Acquisition on the Closing Date.

      Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

      Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.

      Section 14.6 Dispute Resolution.

               (a) Arbitration. The parties hereto agree that any claim,
controversy, dispute or disagreement between or among any of the parties arising
out of or relating to this Agreement shall be governed exclusively by the terms
and provisions of this Section 14.6; provided, however, that within ten (10)
days from the date which any claim, controversy, dispute or disagreement cannot
be resolved and prior to commencing an arbitration procedure pursuant to this
Section 14.6, the parties shall meet to discuss and consider other alternative
dispute resolution procedures other than arbitration including, but not limited
to, Judicial Arbitration & Mediation Services, Inc., if applicable. If at any
time prior to the rendering of the decision by the arbitrator (or pursuant to
such other alternative dispute resolution procedure) as contemplated in this
Section 14.6 to the extent a party makes a written offer to the other party
proposing a settlement of the matter(s) at issue and such offer is rejected,
then the party rejecting such offer shall be obligated to pay the costs and
expenses (excluding the amount of the award granted under the decision) of the
party that offered the settlement from the date such offer was received by such
other party if the decision is for a dollar amount that is less than the amount
of such offer to settle. Notwithstanding the foregoing, the terms and provisions
of this Section 14.6 shall not preclude any party hereto from seeking, or a
court of competent jurisdiction from granting, a temporary restraining order,
temporary injunction or other equitable relief for any breach of (i) any
noncompetition or confidentiality covenant or (ii) any duty, obligation,
covenant, representation or warranty, the breach of which may cause irreparable
harm or damage.

               (b) Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among the parties hereto arising out of or relating to
this Agreement (including any claim based on or arising from an alleged tort)
and the parties hereto have not reached agreement regarding an alternative to
arbitration, the parties agree to select within thirty (30) days of notice by a
party to the other of its desire to seek arbitration under this Section 14.6 one
(1) arbitrator mutually acceptable to APP and the Sellers to hear and decide all
such claims under this Section 14.6. Each of the arbitrators proposed shall be
impartial and independent of all parties. If the parties cannot agree on the
selection of an arbitrator within said 30-day period, then any party may in
writing request the judge of the United States District Court for the
[_____________] District of [__________] senior in term of service to appoint
the arbitrator and, subject to this Section 14.6, such arbitrator shall hear all
arbitration matters arising under this Section 14.6.

<PAGE>   43


               (c) Applicable Rules.

                     (1) Each arbitration hearing shall be held at a place in 
[_____________] acceptable to the arbitrator. The arbitration shall be conducted
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association to the extent such rules do not conflict with the terms hereof;
provided, however, that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including as to rules
of evidence and procedure. The decision of the arbitrator shall be reduced to
writing and shall be binding on the parties and such decision shall contain a
concise statement of the reasons in support of such decision. Judgment upon the
award(s) rendered by the arbitrator may be entered and execution had in any
court of competent jurisdiction or application may be made to such court for a
judicial acceptance of the award and an order of enforcement. The charges and
expenses of the arbitrator shall be shared equally by the parties to the
hearing.

                     (2) The arbitration shall commence within ten (10) days 
after the arbitrator is selected in accordance with the provisions of this
Section 14.6. In fulfilling his duties with respect to determining the amount of
any loss, the arbitrator may consider such matters as, in the opinion of the
arbitrator, are necessary or helpful to make a proper valuation. The arbitrator
may consult with and engage disinterested third parties to advise the
arbitrator. The arbitrator shall not add any interest factor reflecting the time
value of money to the amount of any loss and shall not award any punitive
damages.

                     (3) If the arbitrator selected hereunder should die, resign
or be unable to perform his or her duties hereunder, the parties, or such senior
judge (or such judge's successor) in the event the parties cannot agree, shall
select a replacement arbitrator. The procedure set forth in this Section 14.6
for selecting the arbitrator shall be followed from time to time as necessary.

                     (4) As to any determination of the amount of any loss, or 
as to the resolution of any other claim, controversy, dispute or disagreement,
that under the terms hereof is made subject to arbitration, no lawsuit based on
such claimed loss or such resolution shall be instituted by the parties hereto,
other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 12.7(b).

                     (5) All privileges under [STATE] and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying [STATE] law.

of all parties;

material representation or warranty of the Company or any Stockholder contained
in this Agreement or in any certificate or other document executed and delivered
by the Company or any Stockholder pursuant to this Agreement is or becomes
untrue or breached in any material respect or if the Company or any Stockholder
fails to comply in any material respect with any material covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within thirty (30) days after receipt of written
notice thereof;

<PAGE>   44


               (c) at any time prior to the Effective Date by the Company if any
representation or warranty of APP contained in this Agreement or in any
certificate or other document executed and delivered by APP pursuant to this
Agreement is or becomes untrue in any material respect of if APP fails to comply
in any material respect with any covenant or agreement contained herein, and any
such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

               (d) at any time prior to the Effective Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures, APP
deems termination to be advisable; or

               (e) by APP or the Company if the Merger shall not have been
consummated by September 30, 1997.

      Section 15.2 Effect of Termination. Except as set forth in Section 16.3,
in the event this Agreement is terminated pursuant to this Article XV, this
Agreement shall forthwith become void.

                                   ARTICLE XVI

                    Nondisclosure of Confidential Information

      Section 16.1 Non-Disclosure Covenant. The Company recognizes and
acknowledges that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP and the
Surviving Corporation that is valuable, special and a unique asset of such
entity's business. APP acknowledges that it had in the past, currently has, and
in the future may possibly have, access to certain Confidential Information of
the Company that is valuable, special and a unique asset of each such business.
The Company and APP, severally, agree that they will not disclose such
Confidential Information to any person, firm, corporation, association or other
entity for any purpose or reason whatsoever, except (a) to authorized
representatives of APP, Surviving Corporation and the Company and (b) to counsel
and other advisers to APP, Surviving Corporation and the Company provided that
such advisers (other than counsel) agree to the confidentiality provisions of
this Section 16.1, unless (i) such information becomes available to or known by
the public generally through no fault of the Company or APP, as the case may be,
(ii) disclosure is required by law or the order of any governmental authority
under color of law, provided, that prior to disclosing any information pursuant
to this clause (ii) the Company or APP, as the case may be, shall, if possible,
give prior written notice thereof to the Company or APP and provide the Company
or APP with the opportunity to contest such disclosure, (iii) the disclosing
party reasonably believes that such disclosure is required in connection with
the defense of a lawsuit against the disclosing party, or (iv) the disclosing
party is the sole and exclusive owner of such Confidential Information as a
result of the Merger or otherwise. In the event of a breach or threatened breach
by the Company, on the one hand, and APP, on the other hand, of the provisions
of this Section, APP, the Surviving Corporation and the Company shall be
entitled to an injunction restraining the other party, as the case may be, from
disclosing, in whole or in part, such Confidential Information. Nothing herein
shall be construed as prohibiting any of such parties from pursuing any other
available remedy for such breach or threatened breach, including the recovery of
damages.

      Section 16.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, the Surviving Corporation and the Company agree
that, in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

      Section 16.3 Survival. The obligations of the parties under this Article
XVI shall survive the termination of this Agreement.

                                  Miscellaneous

      Section 17.1 Amendment; Waivers. This Agreement may be amended, modified
or supplemented only by an instrument in writing executed by all the parties
hereto. Any waiver of any terms and conditions hereof must be in writing, and
signed by the parties hereto. The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

      Section 17.2 Assignment. Neither this Agreement nor any right created
hereby or in any agreement entered into in connection with the transactions
contemplated hereby shall be assignable by any party hereto, except by APP to a

relieve APP of its obligations hereunder.

      Section 17.3 Parties in Interest; No Third Party Beneficiaries. Except as
otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. APP acknowledges
and agrees that the rights and remedies of the Company under this Agreement will

rights and remedies of the Company under this Agreement, including, without
limitation, the rights and remedies under Article 14 hereof to indemnification
from APP against Damages incurred by the Stockholders resulting from a breach by
APP of any representation, warranty or covenant of APP contained herein. Except
as provided in the preceding sentence or as otherwise provided herein, neither

confer upon any person not a party hereto or thereto any rights or remedies
hereunder or thereunder.

contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

      Section 17.5 Severability. If any provision of this Agreement is held to
be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

      Section 17.6 Survival of Representations, Warranties and Covenants. The
representations, warranties and covenants contained herein shall survive the
Closing and all statements contained in any certificate, exhibit or other
instrument delivered by or on behalf of the Company, any Stockholder or APP
pursuant to this Agreement shall be deemed to have been representations and
warranties by the Company, such Stockholder and APP. Notwithstanding any
provision in this Agreement to the contrary, the representations and warranties
contained herein shall survive the Closing until the second anniversary of the
Closing Date except that (a) the representations and warranties set forth in
Section 3.21 with respect to environmental matters shall survive for a period of

3.12 is fully covered by policies of insurance of the Company or any Company
Subsidiary as in effect on the date hereof.

      Section 3.13 No Violation of Law. Neither the Company nor any Company
Subsidiary has been, nor shall be as of the Effective Time (by virtue of any
action, omission to act, contract to which it is a party or any occurrence or
state of facts whatsoever), in violation of any applicable local, state or



                                       10

federal law, ordinance, regulation, order, injunction or decree, or any other
requirement of any governmental body, agency, authority or court binding on it,
or relating to its properties, assets or business or its advertising, sales or
pricing practices, except for violations which, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
the Company.

      Section 3.14 Lease Agreements. The Disclosure Schedules contain a true,
accurate and complete list of all the lease agreements and license agreements to
which the Company or any Company Subsidiary is a party and pursuant to which the
Company or any Company Subsidiary leases (whether as lessor or lessee) or
licenses (whether as licensor or licensee) any real or personal property related
to the operation of its business and which requires payments in excess of
$12,000 per year (the "Lease Agreements"). The Company has delivered to APP true
and complete copies of all of the Lease Agreements. Each Lease Agreement is
valid, effective and in full force in accordance with its terms, and there is
not under any such lease (i) any existing or claimed material default by the
Company or any Company Subsidiary (as applicable) or event of material default
or event which with notice or lapse of time, or both, would constitute a
material default by the Company or any Company Subsidiary (as applicable) and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Company, or, (ii) to the knowledge of the Company, any existing
material default by any other party under any of the Lease Agreements or any
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by any such party. To the knowledge of the
Company, there is no pending or threatened reassessment of any property covered
by the Lease Agreements. The Company or any Company Subsidiary will use
reasonable good faith efforts to obtain, prior to the Effective Time, the
consent of each landlord or lessor whose consent is required to the assignment
of the Lease Agreements and will use reasonable good faith efforts to deliver to
APP in writing such consents as are necessary to effect a valid and binding
transfer or assignment of the Company's or any Company Subsidiary's rights
thereunder. The Company has a good, clear, valid and enforceable leasehold
interest under each of the Lease Agreements. The Lease Agreements comply with
the exceptions to ownership interests and compensation arrangements set out in
42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952, and any similar applicable
state law safe harbor or other exemption provisions.

      Section 3.15 Real and Personal Property.

            (a) Neither the Company nor any Company Subsidiary owns any interest
(other than the Lease Agreements) in real property.

            (b) The Company and any Company Subsidiary (i) has good title to all
of its properties and assets (real, personal and mixed, tangible and intangible)
and any rights or interests therein which it purports to own including, without
limitation, all the property and assets reflected in the Company Current
Financial Statements; and (ii) owns such rights, interests, assets and property
free and clear of all Encumbrances, title defects or objections (except for
taxes not yet due and payable). The personal property presently used in
connection with the operation of the business of the Company and the Company
Subsidiaries constitutes the necessary personal property assets to continue
operation of the Company and any Company Subsidiary.

      Section 3.16 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, the Company does not have any
direct or indirect indebtedness for borrowed money, including indebtedness by
way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

      Section 3.17 Contracts and Commitments.

            (a) The Disclosure Schedules contain a true, accurate and complete
list, and the Company has delivered to APP true and complete copies, of each
contract, agreement and other instrument requiring the Company to make future
payments of $10,000 in any fiscal year or $25,000 in the aggregate (other than
insurance contracts identified in Section 3.23 or Lease Agreements identified in
Section 3.14) to which the Company is a party or by which it or any of its
properties or assets are 


                                       11
<PAGE>   17

bound including, without limitation, (i) all agreements between the Company, on
the one hand, and any Payor, government entity, provider, hospital, health

provider, on the other hand, then in effect relating to the provision of
medical, diagnostic imaging or consulting services, treatments, patient
referrals or other similar activities, (ii) all indentures, mortgages, notes,
loan or credit agreements and other agreements and obligations relating to the
borrowing of money or to the direct or indirect guarantee or assumption of
obligations of third parties requiring the Company to make, or setting forth
conditions under which the Company would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of the Company (or any
provider employee of the Company) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by the Company in excess of $10,000 in
any fiscal year or $25,000 in the gregate and that are not cancelable by
providing notice of sixty (60) days or less. All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is with
unrelated third parties and was entered into on an arms-length basis and,
assuming the receipt of the appropriate consents, all will continue to be
binding in accordance with their terms after consummation of the transaction
contemplated herein; there are no contracts, agreements or other instruments to
which the Company is a party or is bound (other than physician employment
contracts and insurance policies) which could either singularly or in the
aggregate have a Material Adverse Effect on the value to APP of the assets and
properties to be acquired by APP from the Company, or which could inhibit or
prevent the Company from transferring to or vesting in APP good and sufficient
title to the assets and properties to be acquired by APP and the Surviving
Corporation except where the failure to transfer would not have a Material
Adverse Effect on APP. In every instance where consent is necessary, the Company
shall, on or before the Closing Date, use reasonable good faith efforts to
obtain and deliver to APP in writing, effective as of the Closing Date, such
consents as are necessary to enable the Surviving Corporation to enjoy all of
the rights now enjoyed by the Company under such contracts. Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that the Company has fully complied with
and is not in default under any provision of the particular contract or
agreement. No contract with a health care provider or Payor has been materially
amended or terminated within the last twelve (12) months.

            (b) The Company (i) has not received notice of any plan or intention
of any other party to exercise any right to cancel or terminate any contract,
agreement or instrument required to be disclosed pursuant to Section 3.17(a),
and to the knowledge of the Company there are no fact(s) that would justify the
exercise of such a right; and (ii) does not currently contemplate, or have
reason to believe any other Person currently contemplates, any amendment or
change to any such contract, agreement or instrument.

      Section 3.18 Employee Matters. The Company does not have employees and is
not currently a party to any employment contract (except for oral employment
agreements which are terminable at will), consulting or collective bargaining

predecessors in interest.

      Section 3.19 Intentionally omitted.

Subsidiary is a party or under which the Company or any Company Subsidiary,
officer or director thereof is or has been covered at any time during the last
five (5) years preceding the date of this Agreement relating to the business of
the Company or any Company Subsidiary (the "Insurance Policies"). All of the
Insurance Policies are valid, outstanding and enforceable policies, except as
may be limited by applicable bankruptcy, insolvency or similar laws affecting
creditors' rights generally or the availability of equitable remedies and all
premiums with respect thereto which are due and payable are currently paid. All
Insurance Policies currently maintained by the Company or any Company Subsidiary

retainages or premiums is threatened. There are no outstanding claims,
settlements or premiums owed against any Insurance Policy, and all required
notices have been given and all known potential or actual claims under any
Insurance Policy have been presented in due and timely fashion. Within the five
(5) years preceding the Agreement, neither the Company nor any Company
Subsidiary has filed a written application for any professional liability
insurance coverage which has been denied by an insurance agency or carrier. The
Disclosure Schedules also set forth a list of all claims under any Insurance
Policy in excess of $10,000 per occurrence filed by the Company or any Company
Subsidiary during the immediately preceding three-year period.

bad debts and, are, to the extent still uncollected, to the knowledge of the
Company collectible in the ordinary course of business, net of reserves for
doubtful and uncollectible accounts shown in the Company Financial Statements or

practice).

patients in the aggregate of the Company. The Company has satisfactory relations

Company that it intends to discontinue its relationship with the Company or to
deny any payments due from, or any claims for payment submitted to any such
party.

December 31, 1996, or which is reasonably expected to account for a dollar
volume of purchases paid for by the Company in excess of $25,000 for the fiscal
year to end December 31, 1997.

      Section 3.26 Inventory. All items of inventory on the Company Current

respect thereto (calculated consistent with past practice), of items of a
quality and a quantity usable and saleable in the ordinary course of the
Company's business and conform to generally accepted standards in the industry
of which the Company is a part. The value of the inventories reflected on the
Company Current Balance Sheet contained in the Company Financial Statements are
net of adequate reserves for damaged, excess, and unusable items. Purchase
commitments of the Company for inventory are not materially in excess of normal
requirements, and none of such purchase commitments are at prices in excess of
prevailing market prices at the time of such purchase commitment.

      Section 3.27 Licenses, Authorization and Provider Programs .

Medicaid provider numbers and participating physician contracts under 1842(h) of
the Social Security Act), and provider agreements, is set forth in the
Disclosure Schedules, true, complete and correct copies of which have been
provided to APP. No violation, default, order or deficiency exists with respect
to any of the items listed in the Disclosure Schedules except for such
violations, defaults, orders or deficiencies which would not be reasonably
likely to have a Material Adverse Effect on the Company, and there is no action
pending or to the Company's knowledge recommended by any state or federal
agencies having jurisdiction over the items listed in the Disclosure Schedules,
either to revoke, withdraw or suspend any material license or to terminate the
participation of the Company in any Governmental Program or Private Program, and
no event has occurred which, with or without notice or lapse of time, or both,
would constitute grounds for a violation, order or deficiency with respect to
any of the items listed in the Disclosure Schedules to revoke, withdraw or
suspend any material license to operate its business as is presently being
conducted by it. To the knowledge of the Company, there has been no decision not
to 



                                       15

Company nor the right of any licensed professional or other individual
affiliated with the Company to receive reimbursements pursuant to any
Governmental Program or Private Program has been terminated or otherwise
materially and adversely affected as a result of any investigation or action
whether by any federal or state governmental regulatory authority or other third
party. No licensed professional or other individual affiliated with the business
has, during the past three (3) years prior to the Effective Time, had their
license limited, suspended or revoked by any governmental regulatory authority
or agency, integrated delivery system, trade association, review organization,
accrediting organization or certifying agency (including orders that have been
entered by any such entities but stayed). True, correct and complete copies of
all reports, correspondence, notices and other documents relating to any matter

corporation duly organized, validly existing and in good standing under the laws
of the state of Delaware, with all requisite corporate power and authority to
own, operate and lease its assets and properties and to carry on its business as
currently conducted. APP is duly qualified to do business as a foreign
corporation and is in good standing in each jurisdiction where the character of
the property owned or leased by it or the nature of its activities makes such
qualification necessary, except where such failure to be so qualified or in good
standing would not have a Material Adverse Effect on APP. Copies of the
certificate of incorporation and all amendments thereto of APP and the bylaws of
APP, as amended, and copies of the corporate minutes of APP regarding the Merger
and the transactions contemplated hereby, all of which have been or will be made
available to the Company for review, are true, correct and complete as in effect
on the date of this Agreement and accurately reflect all material proceedings of
the stockholders and directors of APP (and all committees thereof) regarding the
Merger and the transactions contemplated hereby. The stock record books of APP,
which have been or will be made available to the Company for review, contain
true, complete and accurate records of the stock ownership of APP and the
transfer of the shares of its capital stock.

      Section 4.2 Authorization and Validity. APP has all requisite corporate
power to execute and deliver this Agreement and the Other Agreements and to

transactions contemplated hereby and thereby are within APP's corporate powers
and have been duly authorized by all necessary action on the part of APP's Board
of Directors. This Agreement has and the Other Agreements have been duly
executed by APP. This Agreement and all other agreements and obligations entered
into and undertaken in connection with the Merger and the transactions
contemplated hereby to which APP is a party constitute, or upon execution will

accordance with their respective terms, except as may be limited by bankruptcy
or other laws affecting creditors' rights generally, or by general equity
principles, or by public policy.

      Section 4.3 Governmental Authorization. Other than complying with the
provisions of the applicable state corporate laws regarding the approval of the

documents related to the Merger, and other than consents, filings or
notifications required to be made or obtained solely by the Company, the
execution, delivery and performance by APP of this Agreement and the agreements
provided for herein, and the consummation 




                                       19

issued and outstanding and [10,000,000] shares of APP Preferred Stock, none of
which are outstanding. Each outstanding share of APP Common Stock has been
legally and validly issued and is fully paid and nonassessable, and was issued
pursuant to a valid exemption from registration under (i) the Securities Act of
1933, as amended, and (ii) all applicable state securities laws. No shares of
capital stock are owned by APP in treasury. No shares of capital stock of APP
have been issued or disposed of in violation of the preemptive rights, rights of
first refusal or similar rights of any stockholders of APP. APP has no bonds,
debentures, notes or other obligations the holders of which have the right to
vote (or are convertible into or exercisable for securities having the right to
vote) with the stockholders of APP on any matter. There exist no options,
warrants, subscriptions, calls, commitments or other rights to purchase, or
securities convertible into or exchangeable for, any of the authorized or
outstanding securities of APP and no option, warrant, subscription, call, or
commitment or commission right of any kind exists which obligates APP to issue
any of its authorized but unissued capital stock. APP has no obligation
(contingent or otherwise) to purchase, redeem or otherwise acquire any of its
equity securities or any interests therein or to pay any dividend or make any
distribution in respect thereof.

      Section 4.5 Subsidiaries and Investments. APP does not own, directly or
indirectly, any capital stock or other equity, ownership or proprietary interest
in any corporation, partnership, association, trust, joint venture or other
entity (the "APP Subsidiaries").

      Section 4.6 Absence of Conflicting Agreements or Required Consents. The
execution, delivery and performance of this Agreement by APP and any other
documents contemplated hereby (with or without the giving of notice, the lapse
of time, or both): (i) does not require the consent of any governmental or
regulatory body or authority or any other third party except for such consents,
for which the failure to obtain would not result in a Material Adverse Effect on
APP; (ii) will not conflict with any provision of APP's certificate of
incorporation or bylaws; (iii) will not conflict with, result in a violation of,

order or injunction of any court or governmental instrumentality to which APP is
a party or by which APP or its properties are subject or bound; (iv) will not
conflict with, constitute grounds for termination of, result in a breach of,

party or by which APP or any of its properties are bound except for such
conflict, termination, breach or default, the occurrence of which would not
result in a Material Adverse Effect on APP; and (v) will not create any
Encumbrance or restriction upon APP Common Stock or any of the assets or
properties of APP. The financial statements of APP contained in the Registration
Statements (a) have been prepared in accordance with generally accepted
accounting principles consistently applied (except as may be indicated therein
or in the notes thereto), (b) present fairly the financial position of APP and
APP Subsidiaries as of the dates indicated and present fairly the results of

Effective Time (by virtue of any action, omission to act, contract to which it
is a party or any occurrence or state of facts whatsoever), in violation of any
applicable local, state or federal law, ordinance, regulation, order, injunction
or decree, or any other requirement of any governmental body, agency or
authority or court binding on it, or relating to its property or business or its
advertising, sales or pricing practices, except for violations which are not
reasonably likely, individually or in the aggregate, to have a Material Adverse
Effect on APP.

            (a) The Company shall cooperate with APP to promptly prepare and
file with the SEC the Registration Statements on Form S-1 and Form S-4 (or other
appropriate Forms) to be filed by APP in connection with its Initial Public

circumstances under which they were made, not misleading. The Company shall be
entitled to review the Registration Statements and each of the amendments
thereto, if any, prior to the time each becomes effective under the Securities
Act. The Company shall have no responsibility for information contained in the

information concerning itself, its subsidiaries, directors, officers, partners
and Stockholders, and such other matters as may be reasonably requested by APP

Closing to supplement or amend promptly the Disclosure Schedules with respect to
any matter that would have been or would be required to be set forth or
described in the Disclosure Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Disclosure Schedule that constitutes or
reflects a Material Adverse Effect on the Company may be made unless APP
consents to such amendment or supplement, and no amendment or supplement to a
Disclosure Schedule that constitutes or reflects a Material Adverse Effect on
APP may be made unless the Company consents to such amendment or supplement. For
purposes of this Agreement, including without limitation for 



                                       27

<PAGE>   33

purposes of determining whether the conditions set forth in Sections 10.1 and

Schedule pursuant to this Section 9.2 and APP does not consent to such amendment
or supplement, or APP seeks to amend or supplement a Disclosure Schedule

shall be deemed terminated by mutual consent as set forth in Section 15.1(a)
hereof.

FTC or SEC.

responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by the Company shall be paid by the Company in full
immediately prior to the Closing and such expenses shall be the sole
responsibility of the Stockholders following the Closing Date and not APP.

and information regarding the patients of the Company confidential in accordance
with all applicable laws.

      Section 9.7 Registration Statements. APP shall prepare and file the

of Rule 144(c) under the Securities Act to be met with respect to APP for so
long as those requirements must be met to enable sales by the Stockholders who
are affiliates of the Company to meet the requirements of Rule 145(d) under the

not limited to, fraud and abuse in the Medicare and Medicaid Programs) occurring
on or before the Closing Date, or any overpayment or obligation (or alleged
overpayment or obligation) arising out of or resulting from claims submitted to
any Payor on or before the Closing Date; and

            (c) any liability under the Securities Act, the Exchange Act or any
other federal or state "blue sky" or securities law or regulation, at common law
or otherwise, arising out of or based upon any untrue statement of material fact
in any Registration Statement or any prospectus forming or part thereof, or any
amendment thereof or supplement thereto relating to the Company (including any
Company Subsidiary) or failure to state information necessary to make the
statements required to be stated therein not misleading arising solely from
information provided in writing to APP or its counsel by the Company or any
Stockholder or their agents specifically for inclusion in any such Registration
Statement or any prospectus forming a part thereof, or any amendment thereof or
supplement thereto.

            Notwithstanding anything herein to the contrary, nothing contained

agents, attorneys, consultants and Affiliates harmless from and against all
Damages asserted against or incurred by such individuals and/or entities arising
out of or resulting from:




                                       33

<PAGE>   39

            (a) a breach by APP of any representation or warranty (without
giving effect to any Material Adverse Effect qualifier contained as part of any
such representation or warranty) or covenant of APP contained in this Agreement
or in any schedule or certificate delivered hereunder; and

            (b) any liability under the Securities Act, the Exchange Act or any
other federal or state "blue sky" or securities law or regulation, at common law
or otherwise, arising out of or based upon any untrue statements of material
fact in any Registration Statement or any prospectus forming a part thereof, or
any amendment thereof or supplement thereto, or required to be stated therein or
failure to state information necessary to make the statements therein not
misleading (except for any liability based upon any actual or alleged untrue
statement of material fact or an omission to state a material fact relating the
Company or any Stockholder which was derived from any information provided in
writing by the Company or a Company Subsidiary or any of their agents contained
in the representations and warranties set forth in this Agreement or any
certificate, exhibit, schedule or instrument required to be delivered under this
Agreement).

            Notwithstanding anything herein to the contrary, nothing contained
in this Agreement shall relieve APP of any liability or limit any liability that
it may have in the case of fraud in connection with the transactions
contemplated by this Agreement.

      Section 14.3 Conditions of Indemnification. All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

            (a) Any party claiming indemnification under the Agreement (an
"Indemnified Party") shall promptly (and, in the event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party for whom indemnification is sought (the "Indemnifying
Party) of any third-party claim or claims asserted against the Indemnified Party
("Third Party Claim") that could give rise to a right of indemnification under
this Agreement and (ii) transmit to the Indemnifying Party a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of Damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement. The failure to promptly deliver a Claim Notice shall not relieve any
Indemnifying Party of its obligations to any Indemnified Party with respect to
the related Third Party Claim except to the extent that the resulting delay is
materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (x) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article XIV
with respect to such Third Party Claim and (y) whether the Indemnifying Party
desires, at the sole cost and expense of such Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

            (b) If the Indemnifying Party notifies the Indemnified Party within
the Election Period that the Indemnifying Party elects to assume the defense of
the Third Party Claim, then the Indemnifying Party shall have the right to
defend, at their sole cost and expense, with counsel reasonably acceptable to
such Indemnified Party, such Third Party Claim by all appropriate proceedings,
which proceedings shall be prosecuted diligently by the Indemnifying Party to a
final conclusion or settled at the discretion of the Indemnifying Party in
accordance with this Section 14.3(b). Except as set forth in Section 14.3(f)
below, the Indemnifying Party shall have full control of such defense and
proceedings, including any compromise or settlement thereof. The Indemnified
Party is hereby authorized, at the sole cost and expense of the Indemnifying
Party (but only if the Indemnified Party is entitled to indemnification
hereunder), to file, during the Election Period, any motion, answer or other
pleadings that the Indemnified Party shall deem necessary or appropriate to
protect its interests or those of the Indemnifying Party and not prejudicial to
the Indemnifying Party. If requested by the Indemnifying Party, the Indemnified
Party agrees, at the sole cost and expense of the Indemnifying Party, to
cooperate with the Indemnifying Party and their counsel in contesting any Third
Party Claim that the Indemnifying Party elects to contest, including, without
limitation, the making of any related counterclaim against the person asserting
the Third Party Claim or any cross-complaint against any person. The Indemnified
Party may participate in, but not control, any defense or settlement of any
Third Party Claim controlled by the 




                                       34
<PAGE>   40

Indemnifying Party pursuant to this Section 14.3(b) and shall bear its own costs
and expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnified Party has
been advised by counsel that there may be one or more legal defenses available
to it that are different from or additional to those available to the
Indemnifying Party, then the Indemnified Party may employ separate counsel at
the expense of the Indemnifying Party, and upon written notification thereof,
the Indemnifying Party shall not have the right to assume the defense of such
action on behalf of the Indemnified Party; provided further that the
Indemnifying Party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys at any
time for the Indemnified Party, which firm shall be designated in writing by the
Indemnified Party. Notwithstanding the foregoing, the Indemnifying Party shall
be prohibited from confessing or settling any criminal allegations brought
against the Indemnified Party without the express written consent of the
Indemnified Party.

            (c) If the Indemnifying Party fails to notify the Indemnified Party
within the Election Period that the Indemnifying Party elects to defend the
Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes their potential liability to the Indemnified
Party under this Article XIV and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnified Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to it that are different from or additional
to those available to the Indemnified Party, then the Indemnifying Party may
employ separate counsel and upon written notification thereof, the Indemnified
Party shall not have the right to assume the defense of such action on behalf of
the Indemnifying Party.

            (d) In the event any Indemnified Party should have a claim against
any Indemnifying Party hereunder that does not involve a Third Party Claim, the
Indemnified Party shall transmit to the Indemnifying Party a written notice (the
"Indemnity Notice") describing in reasonable detail the nature of the claim, an
estimate of the amount of damages attributable to such claim and the basis of
the Indemnified Party's request for indemnification under this Agreement. If the
Indemnifying Party does not notify the Indemnified Party within sixty (60) days
from its receipt of the Indemnity Notice that the Indemnifying Party disputes
such claim, the claim specified by the Indemnified Party in the Indemnity Notice
shall be deemed a liability of the Indemnifying Party hereunder. If the
Indemnifying Party has timely disputed such claim, as provided above, such
dispute shall be resolved by litigation in an appropriate court of competent
jurisdiction if the parties do not reach a settlement of such dispute within
thirty (30) days after notice of a dispute is given.

            (e) Payments of all amounts owing by any Indemnifying Party pursuant
to this Article XIV relating to a Third Party Claim shall be made within thirty
(30) days after the latest of (i) the settlement of such Third Party Claim, (ii)
the expiration of the period for appeal of a final adjudication 




                                       35

<PAGE>   41

of such Third Party Claim, or (iii) the expiration of the period for appeal of a
final adjudication of the Indemnifying Party's liability to the Indemnified
Party under this Agreement. Payments of all amounts owing by the Indemnifying
Party pursuant to Section 14.3(d) shall be made within thirty (30) days after
the later of (i) the expiration of the 60-day Indemnity Notice period or (ii)
the expiration of the period for appeal of a final adjudication of the
Indemnifying Party's liability to the Indemnified Party under this Agreement.
During the two-year period following the Effective Date, each Stockholder shall
be entitled to satisfy payments owed to APP by transfer of APP Common Stock from
such Stockholder to APP. For all purposes of this Agreement, the value of each
share of APP Common Stock transferred to APP pursuant to this Agreement shall be
calculated by averaging the daily closing prices for a share of APP Common Stock
for the twenty (20) consecutive trading days on which such shares are actually
traded on the Nasdaq National Market preceding the date of the Claim Notice or
Indemnity Notice, as the case may be. The number of shares of APP Common Stock
permitted to be transferred under this Paragraph 2(e) shall be diminished
proportionately in accordance with the percentage of APP Common Stock released
under the Lock-Up Provisions set forth in Paragraph 1 of the Stockholder
Representation Letter. The rights of any Stockholder to transfer shares of APP
Common Stock in satisfaction of payments owed to APP pursuant to this Agreement
shall terminate upon the earlier of (x) the termination of the Lock-Up
Provisions set forth in the Stockholder Representation Letter or (y) at the end
of the two-year period following the Effective Date.

            (f) The Indemnifying Party shall provide the Indemnified Party with
written notice of any firm offer that is made to settle or compromise a Third
Party Claim against an Indemnified Party. If a firm offer is made to settle such
a claim solely by the payment of money damages and the Indemnifying Party
notifies the Indemnified Party in writing that the Indemnifying Party agrees to
such settlement, but the Indemnified Party elects not to accept and agree to it,
the Indemnified Party may continue to contest or defend such Third Party Claim
and, in such event, the total maximum liability of the Indemnifying Party to
indemnify or otherwise reimburse the Indemnified Party hereunder with respect to
such a claim shall be limited to and shall not exceed the amount of such
settlement offer, plus reasonable out-of-pocket costs and reasonable expenses
(including reasonable attorneys' fees and disbursements) to the date of notice
that the Indemnifying Party desired to accept such settlement.

            (g) Notwithstanding anything contained in this Agreement or the
Merger Agreement to the contrary, the Indemnifying Parties in the aggregate (i)
shall have no obligation hereunder to provide indemnification for the first
$100,000 of Damages (without counting Immaterial Claims as defined below), and
(ii) in no event shall the Indemnifying Parties have any liability hereunder
with respect to any singular incident or a fact involving a breach or inaccuracy
of the Company if the Damages from such claim are equal to or less than $7,500
("Immaterial Claims"). Notwithstanding anything to the contrary contained herein
or in the Merger Agreement, the obligations of each Stockholder hereunder shall
not exceed fifty percent (50%) of the aggregate value of the Merger
Consideration or Exchange Consideration, as the case may be, paid to such
Stockholder pursuant to any Related Acquisition on the Closing Date.

      Section 14.4 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

      Section 14.5 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds, and such correlative
insurance benefit shall be net of the insurance premium, if any, that becomes
due as a result of such claim.

      Section 14.6 Dispute Resolution.




                                       36

<PAGE>   42

            (a) Arbitration. The parties hereto agree that any claim,
controversy, dispute or disagreement between or among any of the parties arising
out of or relating to this Agreement shall be governed exclusively by the terms
and provisions of this Section 14.6; provided, however, that within ten (10)
days from the date which any claim, controversy, dispute or disagreement cannot
be resolved and prior to commencing an arbitration procedure pursuant to this
Section 14.6, the parties shall meet to discuss and consider other alternative
dispute resolution procedures other than arbitration including, but not limited
to, Judicial Arbitration & Mediation Services, Inc., if applicable. If at any
time prior to the rendering of the decision by the arbitrator (or pursuant to
such other alternative dispute resolution procedure) as contemplated in this
Section 14.6 to the extent a party makes a written offer to the other party
proposing a settlement of the matter(s) at issue and such offer is rejected,
then the party rejecting such offer shall be obligated to pay the costs and
expenses (excluding the amount of the award granted under the decision) of the
party that offered the settlement from the date such offer was received by such
other party if the decision is for a dollar amount that is less than the amount
of such offer to settle. Notwithstanding the foregoing, the terms and provisions
of this Section 14.6 shall not preclude any party hereto from seeking, or a
court of competent jurisdiction from granting, a temporary restraining order,
temporary injunction or other equitable relief for any breach of (i) any
noncompetition or confidentiality covenant or (ii) any duty, obligation,
covenant, representation or warranty, the breach of which may cause irreparable
harm or damage.

            (b) Arbitrators. In the event there is a claim, controversy, dispute
or disagreement among the parties hereto arising out of or relating to this
Agreement (including any claim based on or arising from an alleged tort) and the
parties hereto have not reached agreement regarding an alternative to
arbitration, the parties agree to select within thirty (30) days of notice by a
party to the other of its desire to seek arbitration under this Section 14.6 one
(1) arbitrator mutually acceptable to APP and the Sellers to hear and decide all
such claims under this Section 14.6. Each of the arbitrators proposed shall be
impartial and independent of all parties. If the parties cannot agree on the
selection of an arbitrator within said 30-day period, then any party may in
writing request the judge of the United States District Court for the
[_____________] District of [__________] senior in term of service to appoint
the arbitrator and, subject to this Section 14.6, such arbitrator shall hear all
arbitration matters arising under this Section 14.6.

            (c)   Applicable Rules.

                  (1) Each arbitration hearing shall be held at a place in
[_____________] acceptable to the arbitrator. The arbitration shall be conducted
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association to the extent such rules do not conflict with the terms hereof;
provided, however, that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including as to rules
of evidence and procedure. The decision of the arbitrator shall be reduced to
writing and shall be binding on the parties and such decision shall contain a
concise statement of the reasons in support of such decision. Judgment upon the
award(s) rendered by the arbitrator may be entered and execution had in any
court of competent jurisdiction or application may be made to such court for a
judicial acceptance of the award and an order of enforcement. The charges and
expenses of the arbitrator shall be shared equally by the parties to the
hearing.

                  (2) The arbitration shall commence within ten (10) days after
the arbitrator is selected in accordance with the provisions of this Section
14.6. In fulfilling his duties with respect to determining the amount of any
loss, the arbitrator may consider such matters as, in the opinion of the
arbitrator, are necessary or helpful to make a proper valuation. The arbitrator
may consult with and engage disinterested third parties to advise the
arbitrator. The arbitrator shall not add any interest factor reflecting the time
value of money to the amount of any loss and shall not award any punitive
damages.

                  (3) If the arbitrator selected hereunder should die, resign or
be unable to perform his or her duties hereunder, the parties, or such senior
judge (or such judge's successor) in the event the parties cannot agree, shall
select a replacement arbitrator. The procedure set forth in this Section 14.6
for selecting the arbitrator shall be followed from time to time as necessary.

<PAGE>   43

                  (4) As to any determination of the amount of any loss, or as
to the resolution of any other claim, controversy, dispute or disagreement, that
under the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by the parties hereto, other
than to compel arbitration proceedings or enforce the award of the arbitrator,
except as otherwise provided in Section 12.7(b).

                  (5) All privileges under [STATE] and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying [STATE] law.

                                  ARTICLE XV

      Section 15.1 Termination. This Agreement may be terminated and the Merger
and the Acquisitions may be abandoned:

            (a) at any time prior to the Effective Date by mutual agreement of
all parties;

            (b) at any time prior to the Effective Date by APP if any material
representation or warranty of the Company or any Stockholder contained in this
Agreement or in any certificate or other document executed and delivered by the
Company or any Stockholder pursuant to this Agreement is or becomes untrue or
breached in any material respect or if the Company or any Stockholder fails to
comply in any material respect with any material covenant or agreement contained
herein, and any such misrepresentation, noncompliance or breach is not cured,
waived or eliminated within thirty (30) days after receipt of written notice
thereof;

            (c) at any time prior to the Effective Date by the Company if any
representation or warranty of APP contained in this Agreement or in any
certificate or other document executed and delivered by APP pursuant to this
Agreement is or becomes untrue in any material respect of if APP fails to comply
in any material respect with any covenant or agreement contained herein, and any
such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

            (d) at any time prior to the Effective Date by APP if, as a result
of the conduct of due diligence and regulatory compliance procedures, APP deems
termination to be advisable; or

            (e) by APP or the Company if the Merger shall not have been
consummated by September 30, 1997.

      Section 15.2 Effect of Termination. Except as set forth in Section 16.3,
in the event this Agreement is terminated pursuant to this Article XV, this
Agreement shall forthwith become void.

                                  ARTICLE XVI

                   Nondisclosure of Confidential Information

      Section 16.1 Non-Disclosure Covenant. The Company recognizes and
acknowledges that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP and the
Surviving Corporation that is valuable, special and a unique asset of such
entity's business. APP acknowledges that it had in the past, currently has, and
in the future may possibly have, access to certain Confidential Information of
the Company that is valuable, special and a unique asset of each such business.
The Company and APP, severally, agree that they will not disclose such
Confidential Information to any person, firm, corporation, association or other
entity for any purpose or 




                                       38

<PAGE>   44

reason whatsoever, except (a) to authorized representatives of APP, Surviving
Corporation and the Company and (b) to counsel and other advisers to APP,
Surviving Corporation and the Company provided that such advisers (other than
counsel) agree to the confidentiality provisions of this Section 16.1, unless
(i) such information becomes available to or known by the public generally
through no fault of the Company or APP, as the case may be, (ii) disclosure is
required by law or the order of any governmental authority under color of law,
provided, that prior to disclosing any information pursuant to this clause (ii)
the Company or APP, as the case may be, shall, if possible, give prior written
notice thereof to the Company or APP and provide the Company or APP with the
opportunity to contest such disclosure, (iii) the disclosing party reasonably
believes that such disclosure is required in connection with the defense of a
lawsuit against the disclosing party, or (iv) the disclosing party is the sole
and exclusive owner of such Confidential Information as a result of the Merger
or otherwise. In the event of a breach or threatened breach by the Company, on
the one hand, and APP, on the other hand, of the provisions of this Section,
APP, the Surviving Corporation and the Company shall be entitled to an
injunction restraining the other party, as the case may be, from disclosing, in
whole or in part, such Confidential Information. Nothing herein shall be
construed as prohibiting any of such parties from pursuing any other available
remedy for such breach or threatened breach, including the recovery of damages.

      Section 16.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, the Surviving Corporation and the Company agree
that, in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

      Section 16.3 Survival. The obligations of the parties under this Article
XVI shall survive the termination of this Agreement.

                                 ARTICLE XVII

                                 Miscellaneous

      Section 17.1 Amendment; Waivers. This Agreement may be amended, modified
or supplemented only by an instrument in writing executed by all the parties
hereto. Any waiver of any terms and conditions hereof must be in writing, and
signed by the parties hereto. The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

      Section 17.2 Assignment. Neither this Agreement nor any right created
hereby or in any agreement entered into in connection with the transactions
contemplated hereby shall be assignable by any party hereto, except by APP to a
wholly owned subsidiary of APP; provided that any such assignment shall not
relieve APP of its obligations hereunder.

      Section 17.3 Parties in Interest; No Third Party Beneficiaries. Except as
otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. APP acknowledges
and agrees that the rights and remedies of the Company under this Agreement will
be directly available to the Stockholders as third party beneficiaries of the
rights and remedies of the Company under this Agreement, including, without
limitation, the rights and remedies under Article 14 hereof to indemnification
from APP against Damages incurred by the Stockholders resulting from a breach by
APP of any representation, warranty or covenant of APP contained herein. Except
as provided in the preceding sentence or as otherwise provided herein, neither
this Agreement nor any other agreement contemplated hereby shall be deemed to
confer upon any person not a party hereto or thereto any rights or remedies
hereunder or thereunder.

subject matter hereof.

      Section 17.5 Severability. If any provision of this Agreement is held to
be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

representations, warranties and covenants contained herein shall survive the
Closing and all statements contained in any certificate, exhibit or other
instrument delivered by or on behalf of the Company, any Stockholder or APP
pursuant to this Agreement shall be deemed to have been representations and
warranties by the Company, such Stockholder and APP. Notwithstanding any
provision in this Agreement to the contrary, the representations and warranties
contained herein shall survive the Closing until the second anniversary of the
Closing Date except that (a) the representations and warranties set forth in
Section 3.21 with respect to environmental matters shall survive for a period of

incurs liability under the Securities Act, the Exchange Act or any other federal
or state securities law, the representations and warranties set forth therein
shall survive until the expiration of any applicable limitations period.

      Section 17.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS

                                   ARTICLE III

             Representations and Warranties of Sellers and Lexington

            As an inducement to APP to enter into this Agreement, each of Seller
and Lexington represents and warrants to APP both as of the date hereof and as
of the Closing Date as set forth below, subject to those exceptions set forth in
the Disclosure Schedules attached hereto and incorporated herein by this
reference, specifically identifying the relevant subparagraph hereof, which
exceptions shall be deemed to be representations and warranties as if made
hereunder.

            Section 3.1 Organization and Good Standing; Qualification. Lexington
is a limited partnership duly organized and validly existing under the laws of
its state of organization, with all requisite power and authority to own,
operate and lease its assets and properties and to carry on its business as
currently conducted. Lexington is in good standing in each jurisdiction where
the character of the property owned or leased by it or the nature of its
activities makes such qualification necessary, except where such failure to be
so qualified or in good standing would not have a Material Adverse Effect



                                        6

on Lexington. Copies of the Certificate of Limited Partnership and all
amendments thereto of Lexington and the Amended and Restated Agreement of
Limited Partnership of Lexington, and all amendments thereto (the "Partnership
Agreement") and copies of the minutes of Lexington, all of which have been or
will be made available to APP for review, are true and complete as in effect on
the date of this Agreement, and in the case of the minutes, accurately reflect
all material proceedings of the partners of Lexington (and all committees
thereof).

            Section 3.2 Authorization and Validity. Lexington has all requisite
right, power and authority to execute, deliver and perform this Agreement and
all agreements and other documents executed and delivered by it pursuant to this
Agreement or to be executed and delivered on the Closing Date, and has taken all
action required by law, its Certificate of Limited Partnership, its Partnership
Agreement or otherwise, to authorize the execution, delivery and performance of
this Agreement and such related documents. Seller has the legal capacity to
enter into and perform this Agreement and the other agreements to be executed
and delivered in connection herewith. This Agreement and all agreements and
documents executed and delivered in connection herewith have been, or will be as
of the Closing Date, duly executed and delivered by Seller and Lexington and
constitute or will constitute the legal, valid and binding obligations of
Seller, enforceable against Seller and Lexington in accordance with their
respective terms, except as may be limited by applicable bankruptcy, insolvency
or similar laws affecting creditors' rights generally or by general equity
principles, or by public policy.

            Section 3.3 Governmental Authorization. Other than consents, filings
or notifications required to be made or obtained solely by APP (including,
without limitation, in connection with the Initial Public Offering, Form S-4 or
any Hart-Scott-Rodino filing to be made by APP, if any), the execution, delivery
and performance by Seller and Lexington of this Agreement and the agreements
provided for herein, and the consummation of the transactions contemplated
hereby and thereby by Seller and Lexington requires no action by or in respect
of, or filing with, any governmental body, agency, official or authority.

            Section 3.4 Capitalization and Title. The Sellers collectively are,
and will be immediately prior to the Closing Date, the record and beneficial
owners of all the issued and outstanding Partnership Units of Lexington and
Seller is the owner of the Partnership Units currently held in his or her name
on the record books of Lexington, free and clear of all Encumbrances. Each
Partnership Unit held by Seller has been legally and validly issued and is fully
paid and nonassessable, and was issued pursuant to a valid exemption from
registration under (i) the Securities Act and (ii) all applicable state
securities laws.

            Section 3.5 Transactions in Partnership Units. There exist no
Partnership Rights. Except for the General Partner Acquisition referenced
herein, Lexington has no obligation (contingent or otherwise) to purchase,
redeem or otherwise acquire any of its partnership interests or to pay any
dividend or make any distribution in respect thereof. Neither the equity
structure of Lexington nor the relative ownership of partnership interests among
any of its partners has been altered or changed in contemplation of the Exchange
within the two (2) years preceding the date of this Agreement.

            Section 3.6 Continuity of Business Enterprise. There has not been
any sale, distribution or spin-off of significant assets of Lexington or any of
its Affiliates other than in the ordinary course of business within the two (2)
years preceding the date of this Agreement.

            Section 3.7 Subsidiaries and Investments. Lexington does not own,
directly or indirectly, any capital stock or other equity, ownership or
proprietary interest in any corporation, partnership, association, trust, joint
venture or other entity (each a "Partnership Subsidiary").

Agreement and any other documents contemplated hereby (with or without the

any governmental or regulatory body or authority or any other third party except
for such consents, for which the failure to obtain would not result in a
Material Adverse Effect on Lexington; (ii) will not conflict with or result in a
violation of any provision of Lexington's Certificate of Limited Partnership or
Partnership Agreement; (iii) will not conflict with, result in a violation of,
or constitute a default under any law, rule, ordinance, regulation or any

breach of, constitute a default under, require any notice under, or accelerate
or modify, or permit any person to accelerate or modify, any performance
required by the terms of any agreement, instrument, license or permit, to which
Lexington is a party or by which Lexington or any of its properties are subject
or bound except for such conflict, termination, breach or default, the
occurrence of which would not result in a Material Adverse Effect on Lexington;
and (v) except as contemplated by this Agreement, will not create any
Encumbrance or restriction upon the Partnership Units or any of the assets or
properties of Lexington.

            Section 3.9 Absence of Changes. Except as permitted or contemplated

action described in this Section 3.9.

            Section 3.10 No Undisclosed Liabilities. To the best knowledge of
Seller and Lexington, Lexington does not have any liabilities or obligations of
any nature, whether accrued, absolute, contingent or otherwise, asserted or
unasserted except for liabilities or obligations reflected in the Disclosure
Schedules.

            Section 3.11 Litigation and Claims. There are no claims, lawsuits,
actions, arbitrations, administrative or other proceedings, governmental
investigations or inquiries pending or, to the knowledge of Seller and
Lexington, threatened against, or affecting Lexington, any Partnership
Subsidiary, or, to the knowledge of Seller and Lexington, any Seller or any
other licensed professional or other individual affiliated with Lexington
affecting or that would reasonably be likely to affect the Partnership Units or
the operations, business condition (financial or otherwise), or results of
operations of Lexington which (i) if successful, may, individually or in the
aggregate, have a Material Adverse Effect on Lexington or (ii) could adversely
affect the ability of Lexington or any Partnership Subsidiary to effect the
transactions contemplated hereby, and to the knowledge of Seller and Lexington
there is no basis for any such action or any state of facts or occurrence of any
event which would reasonably be likely to give rise to the foregoing. There are
no unsatisfied judgments against Seller, Lexington or any Partnership Subsidiary
or any licensed professional or other individual affiliated with Lexington or
any Partnership Subsidiary relating to services provided on behalf of Lexington
or any Partnership Subsidiary or any consent decrees to which any of the
foregoing is subject. Each of the matters, if any, set forth in this Section

Subsidiary as in effect on the date hereof.

            Section 3.12 No Violation of Law. Neither Lexington nor any

occurrence or state of facts whatsoever), in violation of any applicable local,
state or federal law, ordinance, regulation, order, injunction or decree, or any
other requirement of any governmental body, agency, authority or court binding
on it, or relating to its properties, assets or business or its advertising,
sales or pricing practices, except for violations which, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
Lexington.

            Section 3.13 Lease Agreements. The Disclosure Schedules contain a
true, accurate and complete list of all the lease agreements and license
agreements to which Lexington or any Partnership Subsidiary is a party and
pursuant to which Lexington or any Partnership Subsidiary leases (whether as
lessor or lessee) or licenses (whether as licensor or licensee) any real or
personal property related to the operation of its business and which requires
payments in excess of $12,000 per year (the "Lease Agreements"). Lexington has
delivered to APP true and complete copies of all of the Lease Agreements. Each
Lease Agreement is valid, effective and in full force in accordance with its
terms, and there is not under any such lease (i) any existing or claimed
material default by Lexington or any Partnership Subsidiary (as applicable) or
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by Lexington or any Partnership Subsidiary
(as applicable) and, individually or in the aggregate, may reasonably result in
a Material Adverse Effect on Lexington, or, (ii) to the knowledge of Seller and
Lexington, any existing material default by any other party under any of the
Lease Agreements or any event of material default or event which with notice or
lapse of time, or both, would constitute a material default by any such party.
To the knowledge of Seller and Lexington, there is no pending or threatened
reassessment of any property covered by the Lease Agreements. To the extent
necessary to accomplish the intent of the Agreement, Lexington or any
Partnership Subsidiary shall use reasonable good faith efforts, and Seller shall
use reasonable good faith efforts to cause Lexington, to obtain prior to the
Closing Date the consent of each landlord or lessor whose consent is required to
the assignment of the Lease Agreements and will use reasonable good faith
efforts to deliver to APP in writing such consents as are necessary to effect a
valid and binding transfer or assignment of Lexington's or any Partnership
Subsidiary's rights thereunder. Lexington has a good, clear, valid and
enforceable leasehold interest under each of the Lease Agreements. The Lease
Agreements comply with the exceptions to ownership interests and compensation
arrangements set out in 42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952,
and any similar applicable state law safe harbor or other exemption provisions.

            Section 3.14 Real and Personal Property.

                    (a) Neither Lexington nor each Partnership Subsidiary owns
any interest (other than the Lease Agreements) in real property.

                    (b) Lexington and each Partnership Subsidiary (i) has good
title to all of its properties and assets (real, personal and mixed, tangible
and intangible) and any rights or interests therein which it purports to own;
and (ii) owns such rights, interests, assets and property free and clear of all
Encumbrances, title defects or objections (except for taxes not yet due and
payable). The personal property presently used in connection with the operation
of the business of Lexington and each Partnership Subsidiary constitutes the
necessary personal property assets to continue operation of Lexington and each
Partnership Subsidiary.

            Section 3.15 Indebtedness for Borrowed Money. Except for trade
payables incurred in the ordinary course of business, Lexington does not have
any direct or indirect indebtedness for borrowed money, including indebtedness
by way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

            Section 3.16 Contracts and Commitments.

                    (a) The Disclosure Schedules contain a true, accurate and
complete list, and Lexington has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring Lexington to make future
payments of $10,000 in any fiscal year or $25,000 in the aggregate (other than
insurance contracts identified in Section 3.22 or Lease Agreements identified in
Section 3.13) to which Lexington is a party or by which it or any of its
properties or assets are bound including, without limitation, (i) all agreements
between Lexington, on the one hand, and any government entity, provider,
hospital, health maintenance organization, other managed care organization or
other third-party provider, on the other hand, then in effect relating to the
provision of medical, diagnostic imaging or consulting services, treatments,
patient referrals or other similar activities, (ii) all indentures, mortgages,
notes, loan or credit agreements and other agreements and obligations relating
to the borrowing of money or to the direct or indirect guarantee or assumption
of obligations of third parties requiring Lexington to make, or setting forth
conditions under which Lexington would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(iii) all agreements for capital improvements or acquisitions involving an
amount of $75,000 in any fiscal year or $75,000 in the aggregate, (iv) all
agreements containing a covenant limiting the freedom of Lexington (or any
provider employee of Lexington) to compete in any line of business with any
person or entity or in any geographic area or (v) all written contracts and
commitments providing for future payments by Lexington in excess of $10,000 in
any fiscal year or $25,000 in the aggregate and that are not cancelable by
providing notice of sixty (60) days or less. All such contracts, agreements or
other instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is with
unrelated third parties and was entered into on an arms-length basis in the
ordinary course of business and, assuming the receipt of the appropriate
consents, all will continue to be binding in accordance with their terms after
consummation of the transaction contemplated herein; there are no contracts,
agreements or other instruments to which Lexington is a party or is bound (other
than physician employment contracts and insurance policies) which could either
singularly or in the aggregate have a Material Adverse Effect on the value to
APP of the assets and properties to be acquired by APP from Lexington, or which
could inhibit or prevent Lexington from transferring to or vesting in APP good
and sufficient title to the assets and properties to be acquired by APP except
where the failure to transfer would not have a Material Adverse Effect on APP.
In every instance where consent is necessary, on or before the Closing Date
Lexington shall use reasonable good faith efforts, and Seller shall use
reasonable good faith efforts to cause Lexington, to obtain and deliver to APP
in writing, effective as of the Closing Date, such consents as are necessary to
enable APP to enjoy all of the rights now enjoyed by Lexington under such
contracts. Any and all such consents shall be in a form reasonably acceptable to
APP and shall contain an acknowledgment by the consenting party that Lexington
has fully complied with and is not in default under any provision of the
particular contract or agreement.

                    (b) (i) Neither Lexington nor Seller has received notice of
any plan or intention of any other party to exercise any right to cancel or
terminate any contract, agreement or instrument, and to the knowledge of
Lexington and Seller there are no facts that would justify the exercise of such
a right; and (ii) neither Lexington nor Seller currently contemplates, or has
reason to believe any other Person currently contemplates, any amendment or
change to any such contract, agreement or instrument.

            Section 3.17 Employee Matters. Lexington does not have any employees
and is not currently a party to any employment contract (except for oral
employment agreements which are terminable at will), consulting or collective
bargaining contracts, deferred compensation, pension plan (as defined in Section
3(2) of the Employee Retirement Income Security Act of 1974, as amended, and all
rules and regulations from time to time promulgated thereunder ("ERISA")),
profit sharing, bonus or other nonqualified benefit or compensation commitments,
benefit plans, arrangements or plans (whether written



                                       11

<PAGE>   17

or oral), including all welfare plans (as defined in Section 3(1) of ERISA) of
or pertaining to Lexington and any of its present or former employees, or any
predecessors in interest.

            Section 3.18 Labor Relations. Intentionally omitted.

            Section 3.19 Employee Benefit Plans. Intentionally omitted.

            Section 3.20 Environmental Matters.

                    (a) Neither Lexington nor any Partnership Subsidiary has,
within the five (5) years preceding the date hereof, through the Closing Date,
received from any federal, state or local governmental body, agency, authority
or entity, or any other Person, any written notice, demand, citation, summons,
complaint or order or any notice of any penalty, lien or assessment, and to the
knowledge of Seller and Lexington no investigation or review is pending by any
governmental entity, with respect to any (i) alleged violation by Lexington of
any Environmental Law (as defined in subsection (e) below) (ii) alleged failure
by Lexington to have any environmental permit, certificate, license, approval,
registration or authorization required pursuant to any Environmental Law in
connection with the conduct of its business; or (iii) alleged illegal Regulated
Activity (as defined in subsection (e) below) by Lexington.

                    (b) Neither Lexington nor any Partnership Subsidiary has
used, transported, disposed of or arranged for the disposal of (as those terms
are defined in and construed under the Comprehensive Environmental Response,
Compensation and Liability Act) any Hazardous Substance that would be reasonably
likely to give rise to any Environmental Liabilities for Lexington under any
applicable Environmental Law that had, or would reasonably be likely to have, a
Material Adverse Effect on Lexington. Neither Lexington nor any Partnership
Subsidiary has engaged in any activity or failed to undertake any activity which
action or failure to act has given, or would reasonably be likely to give, rise
to any Environmental Liabilities or enforcement action by any federal, state or
local regulatory agency or authority, or has resulted, or would reasonably be
likely to result, in any fine or penalty imposed pursuant to any Environmental
Law. The Disclosure Schedules disclose any known presence of asbestos in or on
Lexington's or any Partnership Subsidiary's owned or leased premises. To the
knowledge of Seller and Lexington, there is no friable asbestos in or on
Lexington's or any Partnership Subsidiary's owned or leased premises.

                    (c) To the knowledge of Seller and Lexington, no soil or

Lexington or any Partnership Subsidiary is or has been contaminated by any
Hazardous Substance while such assets or premises were owned, leased, operated
or managed, directly or indirectly by Lexington or any Partnership Subsidiary,
where such contamination had, or would be reasonably likely to have, a Material
Adverse Effect on Lexington.

                    (d) There have been no environmental audits and other
similar reports which have been prepared by, for or, to the knowledge of Seller
and Lexington, concerning Lexington or any Partnership Subsidiary within the
five (5) years preceding the date hereof through the Closing Date with respect
to any real property now or previously owned or leased by Lexington, any
Partnership Subsidiary or any of its predecessors, true and complete copies of
which have been provided to APP.

                    (e) For the purposes of this Section 3.20(e), the following
terms have the following meanings:



                                       12

            local laws, ordinances, codes, regulations, rules, policies and
            orders (including without limitation, Medical Waste Laws) that are
            intended to assure the protection of the environment, or that
            classify, regulate, call for the remediation of, require reporting
            with respect to, or list or define air, water, groundwater, solid
            waste, hazardous, toxic, or radioactive substances, materials,
            wastes, pollutants or contaminants, or which are intended to assure
            the safety of employees, workers or other persons, including the
            public in each case as in effect on the date hereof.

                        "Environmental Liabilities" shall mean all liabilities
            of the Company or any Company Subsidiary, whether contingent or
            fixed, which (i) have arisen, or would reasonably be likely to
            arise, under Environmental Laws and (ii) relate to actions occurring
            or conditions existing on or prior to the date hereof or the Closing
            Date.

                        "Hazardous Substances" shall mean any toxic or hazardous
            substances, material or waste, including Medical Waste, or any
            pollutant or contaminant, or infectious or radioactive substance or

            treatment, storage, recycling, transportation, disposal or release
            of any Hazardous Substances.

of any kind or nature necessary to be filed by Lexington with any governmental
agency or authority have been properly completed and timely filed in compliance
with all applicable requirements, except where failure to so file would not have
a Material Adverse Effect on Lexington.

            Section 3.22 Insurance Policies. The Disclosure Schedules list and
briefly describe Lexington's policies of insurance to which Lexington or any
Partnership Subsidiary is a party or under which Lexington or any Partnership
Subsidiary, officer or director thereof is or has been covered at any time
during the last five (5) years preceding the date of this Agreement relating to
the business of Lexington or any Partnership Subsidiary (the "Insurance
Policies"). All of the Insurance Policies are valid, outstanding and enforceable
policies, except as may be limited by applicable bankruptcy, insolvency or
similar laws affecting creditors' rights generally or the availability of
equitable remedies and all premiums with respect thereto which are due and
payable are currently paid. All Insurance Policies currently maintained by
Lexington or any Partnership Subsidiary ("Current Policies") taken together, (i)
provide adequate insurance coverage for the assets, properties and operations of
Lexington and its Affiliates for all risks normally insured against by a Person
carrying on a substantially similar business or businesses as Lexington and its
Affiliates, (ii) are sufficient for compliance with legal and contractual
requirements to which Lexington or any of its Affiliates is a party or by which
any of them may be bound, and (iii) shall be maintained in force (including the
payment of all premiums and compliance with their terms) without interruption up
to and including the Closing Date. True, complete and correct copies of all
Insurance Policies have been provided to APP. Neither Lexington nor any
Partnership Subsidiary nor any officer or partner thereof has received any
notice or other written communication from any issuer of any Current Policy
cancelling such policy, materially increasing any deductibles or retained
amounts thereunder, or materially increasing the annual or other premiums
payable thereunder and, to the knowledge of Seller and Lexington, no such
cancellation or increase of deductibles, retainages or premiums is threatened.
There are no outstanding claims, settlements or premiums owed against any
Insurance Policy, and all required notices have been given and all known
potential or actual claims under any Insurance Policy have been presented in due
and timely fashion. Within the five (5) years preceding the Agreement, neither
Lexington nor any Partnership Subsidiary has filed a written application for any



                                       13

<PAGE>   19

professional liability insurance coverage which has been denied by an insurance
agency or carrier. The Disclosure Schedules also set forth a list of all claims

three-year period.

a list and aging of all accounts receivable of Lexington as of March 31, 1997,
which list is complete, true and accurate in all material respects. All such
accounts receivable arose in the ordinary course of business and have not been
previously written off as bad debts and, are, to the extent still uncollected,
to the knowledge of Seller and Lexington collectible in the ordinary course of
business, net of reserves for doubtful and uncollectible accounts shown on the
accounting records of Lexington (which reserves are adequate and calculated
consistent with past practice).

            Section 3.24 Accounts Payable; Suppliers.

                    (a) The Disclosure Schedules set forth a true and complete
(i) list of the accounts payable of Lexington as of March 31, 1997, and (ii)
list of each individual indebtedness owned by Lexington of $5,000 or more,
setting forth the payee and the amount of indebtedness.

                    (b) The Disclosure Schedules set forth a true, correct and
complete list of the names and addresses of each of the providers/suppliers of

            Section 3.26 Licenses, Authorization and Provider Programs.

                    (a) Lexington and each other licensed employee or contractor

Programs and with such private non-governmental programs (including without
limitation any private insurance program) under which Lexington is presently
receiving payments directly or indirectly from any Payor for technical imaging
services provided by any licensed technician or contractor of Lexington (such
non-governmental programs herein referred to as "Private Programs"). A true,

No violation, default, order or deficiency exists with respect to any of the
items listed in the Disclosure Schedules except for such violations, defaults,
orders or deficiencies which would not be reasonably likely to have a Material
Adverse Effect on Lexington, and there is no action pending or to the knowledge
of Seller and Lexington recommended by any state or federal agencies having
jurisdiction over the items listed in the Disclosure Schedules, either to
revoke, withdraw or suspend any material license or to terminate the
participation of Lexington in any Governmental Program or Private Program, and
no event has occurred which, with or without notice or lapse of time, or both,
would constitute grounds for a violation, order or deficiency with respect to
any of the items listed in the Disclosure Schedules to revoke, withdraw or
suspend any material license to operate its business as is presently being
conducted by it. To the knowledge of Seller and Lexington, there has been no
decision not to renew any existing agreement with any provider or Payor relating
to Lexington's business as presently being conducted by it. Lexington (i) has

Medicare/Medicaid provider status or staff privileges at any hospital or
diagnostic imaging center suspended, relinquished, terminated or revoked
(including orders that have been entered by any such entities but stayed), (ii)

state authority that could result in any demand or reimbursement under the

settlement entered against it in connection with a malpractice or similar
action.

                    (b) Lexington is not required, or for the 72-month period

Lexington, nor the right of any licensed professional or other individual
affiliated with Lexington to receive reimbursements pursuant to any Governmental
Program or Private Program has been terminated or otherwise materially and
adversely affected as a result of any investigation or action whether by any
federal or state governmental regulatory authority or other third party. No
licensed professional or other individual affiliated with the business has,
during the past three (3) years prior to the Closing Date, had their
professional license or staff privileges limited, suspended or revoked by any
governmental regulatory authority or agency, hospital, integrated delivery
system, trade association, professional review organization, accrediting
organization or certifying agency (including orders that have been entered by
any such entities but stayed). True, correct and complete copies of all reports,
correspondence, notices and other documents relating to any matter described or

no outstanding and, to the knowledge of Seller and Lexington, any threatened

Agreement, APP represents and warrants to each Seller and Lexington both as of
the date hereof and as of the Closing Date as set forth below, subject to those

corporation duly organized, validly existing and in good standing under the laws
of the state of Delaware, with all requisite corporate power and authority to
own, operate and lease its assets and properties and to carry on its business as
currently conducted. APP is duly qualified to do business as a foreign
corporation and is in good standing in each jurisdiction where the character of
the property owned or leased by it or the nature of its activities makes such
qualification necessary, except where such failure to be so qualified or in good
standing would not have a Material Adverse Effect on APP. Copies of the
certificate of incorporation and all amendments thereto of APP and the bylaws of
APP, as amended, and copies of the corporate minutes of APP regarding the
transactions contemplated hereby, all of which have been or will be made
available to Sellers and Lexington for review, are true, correct and complete as

proceedings of the stockholders and directors of APP (and all committees
thereof) regarding the transactions contemplated hereby. The stock record books
of APP, which have been or will be made available to Sellers and Lexington for

APP and the transfer of the shares of its capital stock.

of this Agreement, the agreements provided for herein and the Other Agreements,
and the consummation by APP of the transactions contemplated hereby and thereby
are within APP's corporate powers and have been duly authorized by all necessary
action on the part of APP's Board of Directors. This Agreement and the Other
Agreements have been duly executed by APP. This Agreement and all other
agreements and obligations entered into and undertaken in connection with the
transactions contemplated hereby to which APP is a party constitute, or upon
execution will constitute, valid and binding agreements of APP, enforceable
against it in accordance with their respective terms, except as may be limited
by bankruptcy or other laws affecting creditors' rights generally, or by general
equity principles, or by public policy.

            Section 4.3 Governmental Authorization. Other than consents, filings
or notifications required to be made or obtained solely by Lexington, the
execution, delivery and performance by APP of this Agreement and the agreements
provided for herein, and the consummation of the transactions contemplated
hereby and thereby by APP requires no action by or in respect of, or filing
with, any governmental body, agency, official or authority.

            Section 4.4 Capitalization. The authorized capital stock of APP
consists of 20,000,000 shares of APP Common Stock, of which 2,000,000 shares are

which are outstanding. Each outstanding share of APP Common Stock has been
legally and validly issued and is fully paid and nonassessable, and was issued
pursuant to a valid exemption from registration under (i) the Securities Act,
and (ii) all applicable state securities laws. No shares of capital stock are
owned by APP in treasury. No shares of capital stock of APP have been

vote) with the stockholders of APP on any matter. There exist no options,
warrants, subscriptions, calls, commitments or other rights to purchase, or
securities convertible into or exchangeable for, any of the authorized or
outstanding securities of APP and no option, warrant, subscription, call, or
commitment or commission right of any kind exists which obligates APP to issue
any of its authorized but unissued capital stock. APP has no obligation
(contingent or otherwise) to purchase, redeem or otherwise acquire any of its
equity securities or any interests therein or to pay any dividend or make any
distribution in respect thereof.

            Section 4.5 Subsidiaries and Investments. APP does not own, directly
or indirectly, any capital stock or other equity, ownership or proprietary
interest in any corporation, partnership, association, trust, joint venture or
other entity (the "APP Subsidiaries").

            Section 4.6 Absence of Conflicting Agreements or Required Consents.
The execution, delivery and performance of this Agreement by APP and any other
documents contemplated hereby (with or without the giving of notice, the lapse
of time, or both): (i) does not require the consent of any governmental or
regulatory body or authority or any other third party except for such consents,
for which the failure to obtain would not result in a Material Adverse Effect on
APP; (ii) will not conflict with any provision of APP's Certificate of
Incorporation or Bylaws; (iii) will not conflict with, result in a violation of,
or constitute a default under any law, ordinance, regulation, ruling, judgment,
order or injunction of any court or governmental instrumentality to which APP is
a party or by which APP or its properties are subject or bound; (iv) will not
conflict with, constitute grounds for termination of, result in a breach of,

the acceleration of any performance required by the terms of any agreement,

party or by which APP or any of its properties are bound except for such
conflict, termination, breach or default, the occurrence of which would not
result in a Material Adverse Effect on APP; and (v) will not create any
Encumbrance or restriction upon APP Common Stock or any of the assets or
properties of APP. The financial statements of APP contained in the Registration

accounting principles consistently applied (except as may be indicated therein

APP Subsidiaries as of the dates indicated and present fairly the results of

by exhibit or otherwise and (ii) in the case of APP, will, at the time the
Registration Statements and each amendment and supplement thereto, if any,
becomes effective under the Securities Act, none of them contain any untrue
statement of a material fact or omit to state any material fact required to be

circumstances under which they were made, not misleading. Seller and Lexington
shall be entitled to review the Registration Statements and each of the
amendments thereto, if any, prior to the time each becomes effective under the
Securities Act. Seller and Lexington shall have no responsibility for
information contained in the Registration Statements except for information
provided by Seller or Lexington specifically for inclusion therein. Seller's and

Material Adverse Effect on APP may be made unless Sellers and Lexington consent
to such amendment or supplement. For purposes of this Agreement, including

consent as set forth in Section 13.1(a) hereof.

responsible for their own fees and expenses with respect to the transactions

Seller's United States taxpayer identification number;

                    (k) an executed Seller Release by Seller in substantially

                              Post Closing Matters

            Section 11.1 Further Instruments of Transfer. Following the Closing,
at the request of APP and at APP's sole cost and expense, Seller and Lexington
shall deliver any further instruments of transfer and take all reasonable action
as may be necessary or appropriate to carry out the purpose and intent of this
Agreement.

            Section 11.2 Exchange Tax Covenant.

                    (a) The parties intend that the Exchange will qualify as a
tax-free transaction within the meaning of Section 351 of the Code in which the
Company will not recognize gain or loss, and pursuant to which any gain
recognized by Seller as a result of the Exchange will not exceed the amount of
any cash received by a Seller in the Exchange (a "Reorganization").

                    (b) Both prior to and after the Closing Date, all books and
records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Exchange being treated as a
Reorganization. These obligations are excused as to a party required to maintain
the books or file a Tax Return if such party has provided to the other parties a
written opinion of competent tax counsel to the effect that there is not
substantial authority, within the meaning of Section 6662(d)(2)(B)(i) of the
Code, to report the Exchange as a Reorganization and such opinion either is
furnished prior to the Closing Date or is based on facts or events not known at
the Closing Date. Each party shall provide to each other party such tax
information, reports, returns, or schedules as may be reasonably required to
assist such party in accounting for and reporting the Exchange as a
Reorganization.

                    (c) APP shall cause the requirements of Rule 144(c) under
the Securities Act to be met with respect to APP for so long as those
requirements must be met to enable sales by the Sellers who are affiliates of
Lexington to meet the requirements of Rule 145(d) under the Securities Act.

                                   ARTICLE XII

                                    Remedies

            Section 12.1 Indemnification by Sellers. Subject to the terms,
limitations and conditions of this Agreement, Sellers (each an "Indemnifying
Party" and collectively, the "Indemnifying Parties"), severally, agree to
indemnify, defend and hold APP and its directors, officers, employees, agents,
attorneys, consultants and Affiliates (each an "Indemnified Party" and
collectively, the "Indemnified Parties"), harmless from and against all losses,
claims, obligations, demands, assessments, penalties, liabilities, costs,
damages, reasonable attorneys' fees and expenses (including, without limitation,
all costs of experts and all costs incidental to or in connection with any
appellate process) (collectively, "Damages") asserted against or incurred by an
Indemnified Party arising out of or resulting from:

                    (a) a breach of any representation, warranty or covenant of
any Seller or Lexington contained in this Agreement (without giving effect to
any Material Adverse Effect qualifier contained as part of any such
representation or warranty or covenant contained in this Agreement or in any
Schedule or certificate delivered hereunder);

                    (b) any violation (or alleged violation) by any Seller or
Lexington and/or any of its past or present partners, employees, agents,
attorneys, consultants and Affiliates of any state or federal



                                       32

law governing health care fraud and abuse or prohibition on referral of patients
to Persons in which a licensed professional has a financial or other form of
interest (including, but not limited to, fraud and abuse in the Medicare and
Medicaid Programs) occurring on or before the Closing Date; and

                    (c) any liability under the Securities Act, the Exchange Act
or any other federal or state "Blue Sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any (i) untrue statement
of a material fact in any Registration Statement or any prospectus forming a
part thereof, or any amendment thereof or supplement thereto relating to
Lexington (including any Partnership Subsidiary) or (ii) failure to state
information necessary to make the statements required to be stated therein not
misleading arising (in the case of either (i) or (ii)) solely from information
provided in writing to APP or its counsel by Lexington or any Seller or their
agents specifically for inclusion in any such Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto (including, without limitation, schedules, exhibits and certifications
delivered by Lexington or any of its agents in connection with this Agreement).

            Notwithstanding anything herein to the contrary, nothing contained
in this Agreement shall relieve any Seller or Lexington of any liability or
limit any liability that he, she or it may have in the case of fraud in
connection with the transactions contemplated by this Agreement.

            Section 12.2 Indemnification by APP. Subject to the terms,
limitations and conditions of this Agreement, APP (an "Indemnifying Party")
hereby agrees to indemnify, defend and hold the Sellers, and, as applicable,
their respective directors, partners, officers, stockholders, employees, agents,
attorneys, consultants and Affiliates (each an "Indemnified Party" and
collectively, the "Indemnified Parties") harmless from and against all Damages
asserted against or incurred by such individuals and/or entities arising out of
or resulting from:

                    (a) a breach by APP of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of APP contained in
this Agreement or in any schedule or certificate delivered hereunder; and

                    (b) any liability under the Securities Act, the Exchange Act
or any other federal or state "Blue Sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any (i) untrue statements
of a material fact in any Registration Statement or any prospectus forming a
part thereof, or any amendment thereof or supplement thereto or (ii) failure to
state information necessary to make the statements required to be stated therein
not misleading (except for any liability based upon any actual or alleged untrue
statement of material fact or an omission to state a material fact relating to
Lexington or any Seller which was derived from any information provided in
writing by the Company or a Company Subsidiary or any of their agents contained
in the representations and warranties set forth in this Agreement or any
certificate, exhibit, schedule or instrument required to be delivered under this
Agreement.)

            Notwithstanding anything herein to the contrary, nothing contained
in this Agreement shall relieve APP of any liability or limit any liability that
it may have in the case of fraud in connection with the transactions
contemplated by this Agreement.

            Section 12.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                    (a) The Indemnified Party shall promptly (and, in any event,
at least ten (10) days prior to the due date for any responsive pleadings,
filings or other documents) (i) notify each



                                       33

<PAGE>   39

Indemnifying Party of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying
Parties a written notice ("Claim Notice") describing in reasonable detail the
nature of the Third Party Claim, a copy of all papers served with respect to
such claim (if any), an estimate of the amount of Damages attributable to the
Third Party Claim and the basis of the Indemnified Party's request for
indemnification under this Agreement. The failure to promptly deliver a Claim
Notice shall not relieve any Indemnifying Party of its obligations to any
Indemnified Party with respect to the related Third Party Claim except to the
extent that the resulting delay is materially prejudicial to the defense of such
claim. Within thirty (30) days after receipt of any Claim Notice (the "Election
Period"), the Indemnifying Parties shall notify the Indemnified Party (x)
whether the Indemnifying Parties dispute their potential liability to the
Indemnified Party under this Agreement with respect to such Third Party Claim
and (y) whether the Indemnifying Parties desire, at the sole cost and expense of
each Indemnifying Party, to defend the Indemnified Party against such Third
Party Claim.

                    (b) If the Indemnifying Parties notify the Indemnified Party
within the Election Period that the Indemnifying Parties elect to assume the
defense of the Third Party Claim, then the Indemnifying Parties shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party or Indemnified Parties, such Third Party
Claim by all appropriate proceedings, which proceedings shall be prosecuted
diligently by the Indemnifying Parties to a final conclusion or settled at the
discretion of the Indemnifying Parties in accordance with this Section 12.3(b).
Except as set forth in Section 12.3(f) below, the Indemnifying Parties shall
have full control of such defense and proceedings, including any compromise or
settlement thereof. The Indemnified Party is hereby authorized, at the sole cost
and expense of the Indemnifying Parties (but only if the Indemnified Party is
entitled to indemnification hereunder), to file, during the Election Period, any
motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Parties and not prejudicial to the Indemnifying Parties. If requested by the
Indemnifying Parties, the Indemnified Party agrees, at the sole cost and expense
of the Indemnifying Parties, to cooperate with the Indemnifying Parties and
their counsel in contesting any Third Party Claim that the Indemnifying Parties
elect to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person. The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Parties pursuant to this Section 12.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Parties and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Parties, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Parties, and upon written
notification thereof, the Indemnifying Parties shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Parties shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Parties shall be prohibited from confessing or settling any
criminal allegations brought against the Indemnified Party without the express
written consent of the Indemnified Party.

                    (c) If the Indemnifying Parties fail to notify the
Indemnified Party within the Election Period that the Indemnifying Parties elect
to defend the Indemnified Party pursuant to Section 12.3(b), or if the
Indemnifying Parties elect to defend the Indemnified Party pursuant to Section
12.3(b) but fail



                                       34

<PAGE>   40

diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Parties (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Parties to a final conclusion or settled. The Indemnified
Parties shall have full control of such defense and proceedings, provided,
however, that the Indemnified Parties may not enter into, without the
Indemnifying Parties' consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim. Notwithstanding the
foregoing, if the Indemnifying Parties have delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement and if such
dispute is resolved in favor of the Indemnifying Parties, the Indemnifying
Parties shall not be required to bear the costs and expenses of the Indemnified
Parties' defense pursuant to this paragraph or of the Indemnifying Party's
participation therein at the Indemnified Party's request, and the Indemnified
Party shall reimburse the Indemnifying Parties in full for all costs and
expenses of such litigation. The Indemnifying Parties may participate in, but
not control, any defense or settlement controlled by the Indemnified Party
pursuant to this Section 12.3(c), and the Indemnifying Parties shall bear their
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnifying Parties have been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnified Party, then the Indemnifying Parties may employ
separate counsel and upon written notification thereof, the Indemnified Party
shall not have the right to assume the defense of such action on behalf of the
Indemnifying Parties.

                    (d) In the event any Indemnified Party should have a claim
against any Indemnifying Parties hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Parties a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification under
this Agreement. If the Indemnifying Parties do not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Parties dispute such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Parties hereunder. If the Indemnifying Parties have timely disputed such claim,
as provided above, such dispute shall be resolved by the procedures set forth in
Section 12.7.

                    (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Agreement relating to a Third Party Claim shall be made within
thirty (30) days after the latest of (i) the settlement of such Third Party
Claim, (ii) the expiration of the period for appeal of a final adjudication of
such Third Party Claim, or (iii) the expiration of the period for appeal of a
final adjudication of the Indemnifying Parties liability to the Indemnified
Party under this Agreement. Payments of all amounts owing by the Indemnifying
Parties pursuant to Section 12.3(d) shall be made within thirty (30) days after
the later of (i) the expiration of the 60-day Indemnity Notice period or (ii)
the expiration of the period for appeal of a final adjudication of the
Indemnifying Parties liability to the Indemnified Party under this Agreement.
During the two-year period following the Closing Date, each Seller shall be
entitled to satisfy payments owed to APP by transfer of APP Common Stock from
such Seller to APP. For all purposes of this Agreement, the value of each share
of APP Common Stock transferred to APP pursuant to this Agreement shall be
calculated by averaging the daily closing prices for a share of APP Common Stock
for the twenty (20) consecutive trading days on which such shares are actually
traded on the Nasdaq National Market preceding the date of the Claim Notice. The
number of shares of APP Common Stock permitted to be transferred under this
Section 12.3(e) shall be diminished proportionately in accordance with the
percentage of APP Common Stock released under the Lock-Up Provisions set forth
herein. The



                                       35

<PAGE>   41

rights of any Seller to transfer shares of APP Common Stock in satisfaction of
payments owed to APP pursuant to this Agreement shall terminate upon the earlier
of (x) the termination of the Lock-Up Provisions set forth herein or (y) at the
end of the two-year period following the Closing Date.

                    (f) The Indemnifying Parties shall provide the Indemnified
Party with written notice of any firm offer that is made to settle or compromise
a Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Parties notify the Indemnified Party in writing that the Indemnifying Parties
agree to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Parties to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Parties desired to accept such settlement.

                    (g) Notwithstanding anything contained in this Agreement to
the contrary, Indemnifying Parties in the aggregate (i) shall have no obligation
hereunder to provide indemnification for the first [$___________] of Damages
(without counting Immaterial Claims as defined below), and (ii) in no event
shall the Indemnifying Parties have any liability hereunder with respect to any
singular incident or a fact involving a breach or inaccuracy of Lexington if the
Damages from such claim are equal to or less than [$______________] ("Immaterial
Claims"). Notwithstanding anything to the contrary contained herein, the
obligations of each Seller hereunder shall not exceed the value of the Exchange
Consideration paid to such Seller pursuant to the Related Acquisition, if any,
on the Closing Date.

            Section 12.4 Remedies Exclusive. The remedies provided in this
Agreement are the exclusive remedies available to one party against the other,
either at law or in equity, except in the case of fraud.

            Section 12.5 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

            Section 12.6 Tax Benefits; Insurance Proceeds. The total amount of
any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

            Section 12.7 Dispute Resolution.

                    (a) Arbitration. The parties hereto agree that any claim,
controversy, dispute or disagreement between or among any of the parties arising
out of or relating to this Agreement shall be governed exclusively by the terms
and provisions of this Section 12.7; provided, however, that within ten (10)
days from the date which any claim, controversy, dispute or disagreement cannot
be resolved and prior to commencing an arbitration procedure pursuant to this
Section 12.7, the parties shall meet to discuss and consider other alternative
dispute resolution procedures other than arbitration including, but not limited
to, Judicial Arbitration & Mediation Services, Inc., if applicable. If at any
time prior to the rendering of the decision by the arbitrator (or pursuant to
such other alternative dispute resolution



                                       36

<PAGE>   42

procedure) as contemplated in this Section 12.7 to the extent a party makes a
written offer to the other party proposing a settlement of the matter(s) at
issue and such offer is rejected, then the party rejecting such offer shall be
obligated to pay the costs and expenses (excluding the amount of the award
granted under the decision) of the party that offered the settlement from the
date such offer was received by such other party if the decision is for a dollar
amount that is less than the amount of such offer to settle. Notwithstanding the
foregoing, the terms and provisions of this Section 12.7 shall not preclude any
party hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

                    (b) Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among the parties hereto arising out of or relating to
this Agreement (including any claim based on or arising from an alleged tort)
and the parties hereto have not reached agreement regarding an alternative to
arbitration, the parties agree to select within thirty (30) days of notice by a
party to the other of its desire to seek arbitration under this Section 12.7 one
(1) arbitrator mutually acceptable to APP and the Sellers to hear and decide all
such claims under this Section 12.7. Each of the arbitrators proposed shall be
impartial and independent of all parties. If the parties cannot agree on the
selection of an arbitrator within said 30-day period, then any party may in
writing request the judge of the United States District Court for the Western
District of Texas senior in term of service to appoint the arbitrator and,
subject to this Section 12.7, such arbitrator shall hear all arbitration matters
arising under this Section 12.7.

                    (c) Applicable Rules.

                        (1) Each arbitration hearing shall be held at a place in
Boxar County, Texas acceptable to the arbitrator. The arbitration shall be
conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof; provided, however, that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including as to rules
of evidence and procedure. The decision of the arbitrator shall be reduced to
writing and shall be binding on the parties and such decision shall contain a
concise statement of the reasons in support of such decision. Judgment upon the
award(s) rendered by the arbitrator may be entered and execution had in any
court of competent jurisdiction or application may be made to such court for a
judicial acceptance of the award and an order of enforcement. The charges and
expenses of the arbitrator shall be shared equally by the parties to the
hearing.

                        (2) The arbitration shall commence within ten (10) days
after the arbitrator is selected in accordance with the provisions of this
Section 12.7. In fulfilling his duties with respect to determining the amount of
any loss, the arbitrator may consider such matters as, in the opinion of the
arbitrator, are necessary or helpful to make a proper valuation. The arbitrator
may consult with and engage disinterested third parties to advise the
arbitrator. The arbitrator shall not add any interest factor reflecting the time
value of money to the amount of any loss and shall not award any punitive
damages.

                        (3) If the arbitrator selected hereunder should die,
resign or be unable to perform his or her duties hereunder, the parties, or such
senior judge (or such judge's successor) in the event the parties cannot agree,
shall select a replacement arbitrator. The procedure set forth in this Section
12.7 for selecting the arbitrator shall be followed from time to time as
necessary.

                        (4) As to any determination of the amount of any loss,
or as to the resolution of any other claim, controversy, dispute or
disagreement, that under the terms hereof is made subject to



                                       37

<PAGE>   43

arbitration, no lawsuit based on such claimed loss or such resolution shall be
instituted by the parties hereto, other than to compel arbitration proceedings
or enforce the award of the arbitrator, except as otherwise provided in Section
12.7(b).

                        (5) All privileges under Texas and federal law,
including attorney-client and work-product privileges, shall be preserved and
protected to the same extent that such privileges would be protected in a
federal court proceeding applying Texas law.

                                  ARTICLE XIII

                                   Termination

            Section 13.1 Termination. This Agreement may be terminated and the
Exchange may be abandoned:

                    (a) at any time prior to the Closing Date by mutual
agreement of all parties;

                    (b) at any time prior to the Closing Date by APP if any
material representation or warranty of any Seller or Lexington contained in this
Agreement or in any certificate or other document executed and delivered by any
Seller or Lexington pursuant to this Agreement is or becomes untrue or breached
in any material respect or if any Seller or Lexington fails to comply in any
material respect with any material covenant or agreement contained herein, and
any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

                    (c) at any time prior to the Closing Date by Seller as to

eliminated within thirty (30) days after receipt of written notice thereof;

                                   ARTICLE XIV

                    Nondisclosure of Confidential Information

            Section 14.1 Non-Disclosure Covenant. Seller and Lexington recognize
and acknowledge that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP that is
valuable, special and a unique asset of such entity's business. APP acknowledges
that it had in the past, currently has, and in the future may possibly have,
access to certain Confidential Information of Lexington that is valuable,
special and a unique asset of each such business. Seller, Lexington and APP,
severally, agree that they will not disclose such Confidential Information to



                                       38

<PAGE>   44

any person, firm, corporation, association or other entity for any purpose or
reason whatsoever, except (a) to authorized representatives of APP, Seller and
Lexington and (b) to counsel and other advisers to APP, Sellers and Lexington
provided that such advisers (other than counsel) agree to the confidentiality
provisions of this Section 14.1, unless (i) such information becomes available
to or known by the public generally through no fault of Lexington, Seller or
APP, as the case may be, (ii) disclosure is required by law or the order of any
governmental authority under color of law, provided, that prior to disclosing
any information pursuant to this clause (ii) Lexington, Seller or APP, as the
case may be, shall, if possible, give prior written notice thereof to Lexington,
Seller or APP and provide Lexington, Seller or APP with the opportunity to
contest such disclosure, (iii) the disclosing party reasonably believes that
such disclosure is required in connection with the defense of a lawsuit against
the disclosing party, or (iv) the disclosing party is the sole and exclusive
owner of such Confidential Information as a result of the Exchange or otherwise.
In the event of a breach or threatened breach by Seller or Lexington, on the one
hand, and APP, on the other hand, of the provisions of this Section, APP, Seller
and Lexington shall be entitled to an injunction restraining the other party, as
the case may be, from disclosing, in whole or in part, such Confidential
Information. Nothing herein shall be construed as prohibiting any of such
parties from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages.

            Section 14.2 Damages. Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, Seller and Lexington agree that,
in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

            Section 14.3 Survival. The obligations of the parties under this
Article XIV shall survive the termination of this Agreement.

unenforceable provision never comprised a part hereof; and the remaining

any other documents contemplated hereby (with or without the giving of notice,

on Madison; and (v) except as contemplated by this

             (m) agreed, whether in writing or otherwise, to take any action
described in this Section 3.9.

      Section 3.10 No Undisclosed Liabilities. To the best knowledge of Seller
and Madison, Madison does not have any liabilities or obligations of any nature,
whether accrued, absolute, contingent or otherwise, asserted or unasserted
except for liabilities or obligations reflected in the Disclosure Schedules.

      Section 3.11 Litigation and Claims. There are no claims, lawsuits,
actions, arbitrations, administrative or other proceedings, governmental
investigations or inquiries pending or, to the knowledge of Seller and Madison,
threatened against, or affecting Madison, any Partnership Subsidiary, or, to the
knowledge of Seller and Madison, any Seller or any other licensed professional
or other individual affiliated with Madison affecting or that would reasonably
be likely to affect the Partnership Units or the operations, business condition
(financial or otherwise), or results of operations of Madison which (i) if
successful, may, individually or in the aggregate, have a Material Adverse
Effect on Madison or (ii) could adversely affect the ability of Madison or any
Partnership Subsidiary to effect the transactions contemplated hereby, and to
the knowledge of Seller and Madison there is no basis for any such action or any
state of facts or occurrence of any event which would reasonably be likely to
give rise to the foregoing. There are no unsatisfied judgments against Seller,
Madison or any Partnership Subsidiary or any licensed professional or other
individual affiliated with Madison or any Partnership Subsidiary relating to
services provided on behalf of Madison or any Partnership Subsidiary or any
consent decrees to which any of the foregoing is subject. Each of the matters,
if any, set forth in this Section 3.11 is fully covered by policies of insurance
of Madison or any Partnership Subsidiary as in effect on the date hereof.

      Section 3.12 No Violation of Law. Neither Madison nor any Partnership
Subsidiary has been, nor shall be as of the Closing Date (by virtue of any
action, omission to act, contract to which it is a party or any occurrence or
state of facts whatsoever), in violation of any applicable local, state or
federal law, ordinance, regulation, order, injunction or decree, or any other
requirement of any governmental body, agency, authority or court binding on it,
or relating to its properties, assets or business or its advertising, sales or
pricing practices, except for violations which, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
Madison.

      Section 3.13 Lease Agreements. The Disclosure Schedules contain a true,
accurate and complete list of all the lease agreements and license agreements to
which Madison or any Partnership Subsidiary is a party and pursuant to which
Madison or any Partnership Subsidiary leases (whether as lessor or lessee) or
licenses (whether as licensor or licensee) any real or personal property related
to the operation of its business and which requires payments in excess of
$12,000 per year (the "Lease Agreements"). Madison has delivered to APP true and
complete copies of all of the Lease Agreements. Each Lease Agreement is valid,
effective and in full force in accordance with its terms, and there is not under
any such lease (i) any existing or claimed material default by Madison or any
Partnership Subsidiary (as applicable) or event of material default or event
which with notice or lapse of time, or both, would constitute a material default
by Madison or any Partnership Subsidiary (as applicable) and, individually or in
the aggregate, may reasonably result in a Material Adverse Effect on Madison,
or, (ii) to the knowledge of Seller and Madison, any existing material default
by any other party under any of the Lease Agreements or any event of material
default or event which with notice or lapse of time, or both, would constitute a
material default by any such party. To the knowledge of Seller and Madison,
there is no pending or threatened reassessment of any property covered by the
Lease Agreements. To the extent necessary to accomplish the intent of the
Agreement, Madison or any Partnership Subsidiary shall use reasonable good faith
efforts, and Seller shall use reasonable good faith efforts to cause



                                        9

<PAGE>   15

Madison, to obtain prior to the Closing Date the consent of each landlord or
lessor whose consent is required to the assignment of the Lease Agreements and
will use reasonable good faith efforts to deliver to APP in writing such
consents as are necessary to effect a valid and binding transfer or assignment
of Madison's or any Partnership Subsidiary's rights thereunder. Madison has a
good, clear, valid and enforceable leasehold interest under each of the Lease
Agreements. The Lease Agreements comply with the exceptions to ownership
interests and compensation arrangements set out in 42 U.S.C. Section 1395nn, 42
C.F.R. Section 1001.952, and any similar applicable state law safe harbor or
other exemption provisions.

      Section 3.14 Real and Personal Property.

            (a) Neither Madison nor each Partnership Subsidiary owns any
interest (other than the Lease Agreements) in real property.

            (b) Madison and each Partnership Subsidiary (i) has good title to
all of its properties and assets (real, personal and mixed, tangible and
intangible) and any rights or interests therein which it purports to own; and
(ii) owns such rights, interests, assets and property free and clear of all
Encumbrances, title defects or objections (except for taxes not yet due and
payable). The personal property presently used in connection with the operation
of the business of Madison and each Partnership Subsidiary constitutes the
necessary personal property assets to continue operation of Madison and each
Partnership Subsidiary.

      Section 3.15 Indebtedness for Borrowed Money. Except for trade payables
incurred in the ordinary course of business, Madison does not have any direct or
indirect indebtedness for borrowed money, including indebtedness by way of
lease-purchase arrangements or guarantees, and is not obligated in any manner
(actual or contingent) to assume or guarantee any indebtedness or obligation of
another Person.

      Section 3.16 Contracts and Commitments.

            (a) The Disclosure Schedules contain a true, accurate and complete
list, and Madison has delivered to APP true and complete copies, of each
contract, agreement and other instrument requiring Madison to make future
payments of $10,000 in any fiscal year or $25,000 in the aggregate (other than
insurance contracts identified in Section 3.22 or Lease Agreements identified in
Section 3.13) to which Madison is a party or by which it or any of its
properties or assets are bound including, without limitation, (i) all agreements
between Madison, on the one hand, and any government entity, provider, hospital,
health maintenance organization, other managed care organization or other
third-party provider, on the other hand, then in effect relating to the
provision of medical, diagnostic imaging or consulting services, treatments,
patient referrals or other similar activities, (i) all indentures, mortgages,
notes, loan or credit agreements and other agreements and obligations relating
to the borrowing of money or to the direct or indirect guarantee or assumption
of obligations of third parties requiring Madison to make, or setting forth
conditions under which Madison would be required to make, aggregate future
payments in excess of $10,000 in any fiscal year or $25,000 in the aggregate,
(ii) all agreements for capital improvements or acquisitions involving an amount
of $75,000 in any fiscal year or $75,000 in the aggregate, (iii) all agreements
containing a covenant limiting the freedom of Madison (or any provider employee
of Madison) to compete in any line of business with any person or entity or in
any geographic area or (iv) all written contracts and commitments providing for
future payments by Madison in excess of $10,000 in any fiscal year or $25,000 in
the aggregate and that are not cancelable by providing notice of sixty (60) days
or less. All such contracts, agreements or other instruments are in full force
and effect, there has been no threatened cancellation thereof, there are no
outstanding disputes thereunder, each is with unrelated third parties and was
entered into on an arms-length basis in the ordinary course



                                       10

<PAGE>   16

of business and, assuming the receipt of the appropriate consents, all will
continue to be binding in accordance with their terms after consummation of the
transaction contemplated herein; there are no contracts, agreements or other
instruments to which Madison is a party or is bound (other than physician
employment contracts and insurance policies) which could either singularly or in
the aggregate have a Material Adverse Effect on the value to APP of the assets
and properties to be acquired by APP from Madison, or which could inhibit or
prevent Madison from transferring to or vesting in APP good and sufficient title
to the assets and properties to be acquired by APP except where the failure to
transfer would not have a Material Adverse Effect on APP. In every instance
where consent is necessary, on or before the Closing Date Madison shall use
reasonable good faith efforts, and Seller shall use reasonable good faith
efforts to cause Madison, to obtain and deliver to APP in writing, effective as
of the Closing Date, such consents as are necessary to enable APP to enjoy all
of the rights now enjoyed by Madison under such contracts. Any and all such
consents shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that Madison has fully complied with and
is not in default under any provision of the particular contract or agreement.

             (b) (i) Neither Madison nor Seller has received notice of any plan
or intention of any other party to exercise any right to cancel or terminate any
contract, agreement or instrument, and to the knowledge of Madison and Seller
there are no facts that would justify the exercise of such a right; and (ii)
neither Madison nor Seller currently contemplates, or has reason to believe any
other Person currently contemplates, any amendment or change to any such
contract, agreement or instrument.

      Section 3.17 Employee Matters. Madison does not have any employees and is
not currently a party to any employment contract (except for oral employment
agreements which are terminable at will), consulting or collective bargaining
contracts, deferred compensation, pension plan (as defined in Section 3(2) of
the Employee Retirement Income Security Act of 1974, as amended, and all rules
and regulations from time to time promulgated thereunder ("ERISA")), profit
sharing, bonus or other nonqualified benefit or compensation commitments,
benefit plans, arrangements or plans (whether written or oral), including all
welfare plans (as defined in Section 3(1) of ERISA) of or pertaining to Madison
and any of its present or former employees, or any predecessors in interest.

      Section 3.18 Labor Relations.  Intentionally omitted.

      Section 3.19 Employee Benefit Plans.  Intentionally omitted.

      Section 3.20 Environmental Matters.

             (a) Neither Madison nor any Partnership Subsidiary has, within the
five (5) years preceding the date hereof, through the Closing Date, received
from any federal, state or local governmental body, agency, authority or entity,
or any other Person, any written notice, demand, citation, summons, complaint or
order or any notice of any penalty, lien or assessment, and to the knowledge of
Seller and Madison no investigation or review is pending by any governmental
entity, with respect to any (i) alleged violation by Madison of any
Environmental Law (as defined in subsection (e) below) (ii) alleged failure by
Madison to have any environmental permit, certificate, license, approval,
registration or authorization required pursuant to any Environmental Law in
connection with the conduct of its business; or (iii) alleged illegal Regulated
Activity (as defined in subsection (e) below) by Madison.

             (b) Neither Madison nor any Partnership Subsidiary has used,
transported, disposed of or arranged for the disposal of (as those terms are
defined in and construed under the Comprehensive Environmental Response,
Compensation and Liability Act) any Hazardous Substance that would be reasonably
likely to give rise to any Environmental Liabilities for Madison under any
applicable



                                       11

<PAGE>   17

Environmental Law that had, or would reasonably be likely to have, a Material
Adverse Effect on Madison. Neither Madison nor any Partnership Subsidiary has
engaged in any activity or failed to undertake any activity which action or
failure to act has given, or would reasonably be likely to give, rise to any
Environmental Liabilities or enforcement action by any federal, state or local
regulatory agency or authority, or has resulted, or would reasonably be likely
to result, in any fine or penalty imposed pursuant to any Environmental Law. The
Disclosure Schedules disclose any known presence of asbestos in or on Madison's
or any Partnership Subsidiary's owned or leased premises. To the knowledge of
Seller and Madison, there is no friable asbestos in or on Madison's or any
Partnership Subsidiary's owned or leased premises.

             (c) To the knowledge of Seller and Madison, no soil or water in or
under any assets currently or formerly held for use or sale by Madison or any
Partnership Subsidiary is or has been contaminated by any Hazardous Substance
while such assets or premises were owned, leased, operated or managed, directly

had, or would be reasonably likely to have, a Material Adverse Effect on
Madison.

             (d) There have been no environmental audits and other similar
reports which have been prepared by, for or, to the knowledge of Seller and
Madison, concerning Madison or any Partnership Subsidiary within the five (5)
years preceding the date hereof through the Closing Date with respect to any
real property now or previously owned or leased by Madison, any Partnership
Subsidiary or any of its predecessors, true and complete copies of which have
been provided to APP.

             (e) For the purposes of this Section 3.20(e), the following terms
have the following meanings:

            "Environmental Laws" shall mean any federal, state or local laws,
      ordinances, codes, regulations, rules, policies and orders (including
      without limitation, Medical Waste Laws) that are intended to assure the
      protection of the environment, or that classify, regulate, call for the
      remediation of, require reporting with respect to, or list or define air,
      water, groundwater, solid waste, hazardous, toxic, or radioactive
      substances, materials, wastes, pollutants or contaminants, or which are
      intended to assure the safety of employees, workers or other persons,
      including the public in each case as in effect on the date hereof.

            "Environmental Liabilities" shall mean all liabilities of the
      Company or any Company Subsidiary, whether contingent or fixed, which (i)

      Section 3.22 Insurance Policies. The Disclosure Schedules list and briefly
describe Madison's policies of insurance to which Madison or any Partnership
Subsidiary is a party or under which Madison or any Partnership Subsidiary,
officer or director thereof is or has been covered at any time during the last
five (5) years preceding the date of this Agreement relating to the business of
Madison or any Partnership Subsidiary (the "Insurance Policies"). All of the
Insurance Policies are valid, outstanding and enforceable policies, except as
may be limited by applicable bankruptcy, insolvency or similar laws affecting
creditors' rights generally or the availability of equitable remedies and all
premiums with respect thereto which are due and payable are currently paid. All
Insurance Policies currently maintained by Madison or any Partnership Subsidiary
("Current Policies") taken together, (i) provide adequate insurance coverage for
the assets, properties and operations of Madison and its Affiliates for all
risks normally insured against by a Person carrying on a substantially similar
business or businesses as Madison and its Affiliates, (ii) are sufficient for
compliance with legal and contractual requirements to which Madison or any of
its Affiliates is a party or by which any of them may be bound, and (iii) shall
be maintained in force (including the payment of all premiums and compliance
with their terms) without interruption up to and including the Closing Date.
True, complete and correct copies of all Insurance Policies have been provided
to APP. Neither Madison nor any Partnership Subsidiary nor any officer or
partner thereof has received any notice or other written communication from any
issuer of any Current Policy cancelling such policy, materially increasing any
deductibles or retained amounts thereunder, or materially increasing the annual
or other premiums payable thereunder and, to the knowledge of Seller and
Madison, no such cancellation or increase of deductibles, retainages or premiums
is threatened. There are no outstanding claims, settlements or premiums owed
against any Insurance Policy, and all required notices have been given and all
known potential or actual claims under any Insurance Policy have been presented
in due and timely fashion. Within the five (5) years preceding the Agreement,
neither Madison nor any Partnership Subsidiary has filed a written application
for any professional liability insurance coverage which has been denied by an
insurance agency or carrier. The Disclosure Schedules also set forth a list of
all claims under any Insurance Policy in excess of $10,000 per occurrence filed
by Madison or any Partnership Subsidiary during the immediately preceding
three-year period.

      Section 3.23 Accounts Receivable. The Disclosure Schedules set forth a
list and aging of all accounts receivable of Madison as of March 31, 1997, which
list is complete, true and accurate in all material respects. All such accounts
receivable arose in the ordinary course of business and have not been previously
written off as bad debts and, are, to the extent still uncollected, to the
knowledge of Seller and Madison collectible in the ordinary course of business,
net of reserves for doubtful and uncollectible accounts shown on the accounting
records of Madison (which reserves are adequate and calculated consistent with
past practice).

      Section 3.24 Accounts Payable; Suppliers.

             (a) The Disclosure Schedules set forth a true and complete (i) list
of the accounts payable of Madison as of March 31, 1997, and (ii) list of each
individual indebtedness owned by Madison of $5,000 or more, setting forth the
payee and the amount of indebtedness.

             (b) The Disclosure Schedules set forth a true, correct and complete
list of the names and addresses of each of the providers/suppliers of products
or services to Madison (including, without limitation all providers of care to
patients) which accounted for a dollar volume of purchases paid for by Madison
in excess of $25,000 for the fiscal year ended [DECEMBER 31, 1996], or which is
reasonably expected to account for a dollar volume of purchases paid for by
Madison in excess of $25,000 for the fiscal year to end [DECEMBER 31, 1997].



                                       13

<PAGE>   19

      Section 3.25 Inventory. All items of inventory on hand on the date of this
Agreement consist, and all such items on hand on the Closing Date will consist,
net of all applicable reserves with respect thereto (calculated consistent with
past practice), of items of a quality and a quantity usable and saleable in the
ordinary course of Madison's business and conform to generally accepted
standards in the industry of which Madison is a part. Purchase commitments of
Madison for inventory are not materially in excess of normal requirements, and
none of such purchase commitments are at prices in excess of prevailing market
prices at the time of such purchase commitment.

      Section 3.26 Licenses, Authorization and Provider Programs.

             (a) Madison and each other licensed employee or contractor of
Madison (i) is the holder of all valid licenses, approvals, orders, consents,
permits, registrations, qualifications and other rights and authorizations
required by law, ordinance, regulation or ruling of any governmental regulatory
authority necessary to operate his/her/its business and (ii) is eligible to
participate in and to receive reimbursement under Titles XVIII and XIX of the
Social Security Act (the "Medicare and Medicaid Programs") and any other
programs funded in whole or in part by federal, state or local entities for
which Madison is eligible ("Governmental Programs"). Each of Madison and Seller
has a current provider number for such Governmental Programs and with such
private non-governmental programs (including without limitation any private
insurance program) under which Madison is presently receiving payments directly
or indirectly from any Payor for technical imaging services provided by any
licensed technician or contractor of Madison (such non-governmental programs
herein referred to as "Private Programs"). A true, correct and complete list of
such licenses, permits and other authorizations (including, but not limited to
verification of Medicare and Medicaid provider numbers and participating
physician contracts under 1842(h) of the Social Security Act) and provider
agreements is set forth in the Disclosure Schedules, true, complete and correct
copies of which have been provided to APP. No violation, default, order or
deficiency exists with respect to any of the items listed in the Disclosure
Schedules except for such violations, defaults, orders or deficiencies which
would not be reasonably likely to have a Material Adverse Effect on Madison, and
there is no action pending or to the knowledge of Seller and Madison recommended
by any state or federal agencies having jurisdiction over the items listed in
the Disclosure Schedules, either to revoke, withdraw or suspend any material
license or to terminate the participation of Madison in any Governmental Program
or Private Program, and no event has occurred which, with or without notice or
lapse of time, or both, would constitute grounds for a violation, order or
deficiency with respect to any of the items listed in the Disclosure Schedules
to revoke, withdraw or suspend any material license to operate its business as
is presently being conducted by it. To the knowledge of Seller and Madison,
there has been no decision not to renew any existing agreement with any provider
or Payor relating to Madison's business as presently being conducted by it.
Madison (i) has not had its professional license, Drug Enforcement Agency
number, Medicare/Medicaid provider status or staff privileges at any hospital or
diagnostic imaging center suspended, relinquished, terminated or revoked
(including orders that have been entered by any such entities but stayed), (ii)
has not been reprimanded in writing, sentenced, or disciplined by any licensing
board, state agency, regulatory body or authority, hospital, Payor or specialty
board (including orders that have been entered by any such entities but stayed),
(iii) is not the subject of an initial or final determination by any federal or
state authority that could result in any demand or reimbursement under the
Medicare, Medicaid or Government Programs or any exclusion or which monetary
penalty under federal or state law or (iv) has had a final judgment or
settlement entered against it in connection with a malpractice or similar
action.

             (b) Madison is not required, or for the 72-month period prior to
the Closing Date was not required, to file any cost reports or other reports
with any Governmental Program or Private Program.

      Section 3.27 Inspections and Investigations. Neither the right of Madison,
nor the right of any licensed professional or other individual affiliated with
Madison to receive reimbursements pursuant to any Governmental Program or
Private Program has been terminated or otherwise materially and adversely
affected as a result of any investigation or action whether by any federal or
state governmental regulatory authority or other third party. No licensed
professional or other individual affiliated with the business has, during the
past three (3) years prior to the Closing Date, had their professional license
or staff privileges limited, suspended or revoked by any governmental regulatory
authority or agency, hospital, integrated delivery system, trade association,
professional review organization, accrediting organization or certifying agency
(including orders that have been entered by any such entities but stayed). True,
correct and complete copies of all reports, correspondence, notices and other
documents relating to any matter described or referenced in this Section 3.27
have been provided to APP.

      Section 3.28 Proprietary Rights and Information.

             (a) Set forth in the Disclosure Schedules is a complete and
accurate list and summary description of the following: (i) all trademarks

APP, as amended, and copies of the corporate minutes of APP regarding the
transactions contemplated hereby, all of which have been or will be made
available to Sellers and Madison for review, are true, correct and complete as

redeem or otherwise acquire any of its equity securities or any interests
therein or to pay any dividend or make any distribution in respect thereof.

      Section 4.5 Subsidiaries and Investments. APP does not own, directly or

      APP, Seller and Madison agree as follows:

      Section 7.1 Filings; Other Action.

      (a) Madison shall cooperate with APP to promptly prepare and file with the
SEC the Registration Statements on Form S-1 and Form S-4 (or other appropriate
Forms) to be filed by APP in connection with its Initial Public Offering and
offering of the shares of APP Common Stock to the Target Interest Holders

concerning Madison as may be reasonably requested in connection with any such
action in a timely manner.

      (b) Seller, Madison and APP and each separately represent and warrant that
(i) in the case of Seller and Madison, none of the written information or
documents supplied or to be supplied by Seller and Madison specifically for
inclusion in the Registration Statements, by exhibit or otherwise and (ii) in
the case of APP, will, at the time the Registration Statements and each
amendment and supplement thereto, if any, becomes effective under the Securities
Act, none of them contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. Seller and Madison shall be entitled to review the
Registration Statements and each of the amendments thereto, if any, prior to the
time each becomes effective under the Securities Act. Seller and Madison shall
have no responsibility for information contained in the Registration Statements
except for information provided by Seller or Madison specifically for inclusion

diminish or otherwise affect the representations, covenants and warranties of
APP contained in this Agreement.

      (c) Seller and Madison shall, upon request, furnish APP with all
information concerning Madison, its subsidiaries, partners and officers, and
such other matters as may be reasonably requested by APP in connection with the

supplement or amend promptly the Schedules with respect to any matter that would
have been or would be required to be set forth or described in the Schedules in
order to not materially breach any representation, warranty or covenant of such
party contained herein; provided that no amendment or supplement to a Schedule
that constitutes or reflects a Material Adverse Effect on Madison may be made
unless APP consents to such amendment or supplement, and no amendment or
supplement to a Schedule that constitutes or reflects a Material Adverse Effect
on APP may be made unless Sellers and Madison consent to such amendment or
supplement. For purposes of this Agreement, including without limitation for
purposes of determining whether the conditions set forth in Sections 8.1 and 9.1
have been fulfilled, the Disclosure Schedules hereto shall be deemed to be the



                                       26

pursuant to this Section 7.2, and Seller and Madison do not consent, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
13.1(a) hereof.

prevent the Exchange from qualifying as a tax-free exchange within the meaning
of Section 351 of the Code.

each other before issuing any press release or making any public statement with

make any such public statement prior to such consultation, although the
foregoing shall not apply to any disclosure by APP in any filing with the DOJ,
FTC or SEC.

      Section 7.5 Expenses. Each party to this Agreement shall be solely
responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees
and expenses incurred by Seller and Madison shall be paid by Seller in full
immediately prior to the Closing.

Registration Statements with the SEC, and shall use its reasonable good faith
efforts to cause the Registration Statements to become effective under the
Securities Act and take any action required to be taken under the applicable
state "Blue Sky" or other securities laws in connection with the issuance of the
shares of APP Common Stock upon consummation of the transactions contemplated

representations and warranties set forth in this Agreement or any certificate,
exhibit, schedule or instrument required to be delivered under this Agreement.)

      Notwithstanding anything herein to the contrary, nothing contained in this
Agreement shall relieve APP of any liability or limit any liability that it may
have in the case of fraud in connection with the transactions contemplated by
this Agreement.

      Section 12.3 Conditions of Indemnification. All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

             (a) The Indemnified Party shall promptly (and, in any event, at
least ten (10) days prior to the due date for any responsive pleadings, filings
or other documents) (i) notify each Indemnifying Party of any third-party claim
or claims asserted against the Indemnified Party ("Third Party Claim") that
could give rise to a right of indemnification under this Agreement and (ii)
transmit to the Indemnifying Parties a written notice ("Claim Notice")
describing in reasonable detail the nature of the Third Party Claim, a copy of
all papers served with respect to such claim (if any), an estimate of the amount
of Damages attributable to the Third Party Claim and the basis of the
Indemnified Party's request for indemnification under this Agreement. The
failure to promptly deliver a Claim Notice shall not relieve any Indemnifying
Party of its obligations to any Indemnified Party with respect to the related
Third Party Claim except to the extent that the resulting delay is materially
prejudicial to the defense of such claim. Within thirty (30) days after receipt
of any Claim Notice (the "Election Period"), the Indemnifying Parties shall
notify the Indemnified Party (x) whether the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement with respect
to such Third Party Claim and (y) whether the Indemnifying Parties desire, at
the sole cost and expense of each Indemnifying Party, to defend the Indemnified
Party against such Third Party Claim.

             (b) If the Indemnifying Parties notify the Indemnified Party within
the Election Period that the Indemnifying Parties elect to assume the defense of
the Third Party Claim, then the Indemnifying Parties shall have the right to
defend, at their sole cost and expense, with counsel reasonably acceptable to
such Indemnified Party or Indemnified Parties, such Third Party Claim by all
appropriate proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Parties to a final conclusion or settled at the discretion of the
Indemnifying Parties in accordance with this Section 12.3(b). Except as set
forth in Section 12.3(f) below, the Indemnifying Parties shall have full control
of such defense and proceedings, including any compromise or settlement thereof.
The Indemnified Party is hereby authorized, at the sole cost and expense of the
Indemnifying Parties (but only if the Indemnified Party is entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings that the Indemnified Party shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Parties and
not prejudicial to the Indemnifying Parties. If requested by the Indemnifying
Parties, the Indemnified Party agrees, at the sole cost and expense of the
Indemnifying Parties, to cooperate with the Indemnifying Parties and their
counsel in contesting any Third Party Claim that the Indemnifying Parties elect
to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person. The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Parties pursuant to this Section 12.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Parties and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Parties, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying



                                       33

<PAGE>   39

Parties, and upon written notification thereof, the Indemnifying Parties shall
not have the right to assume the defense of such action on behalf of the
Indemnified Party; provided further that the Indemnifying Parties shall not, in
connection with any one such action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
more than one separate firm of attorneys at any time for the Indemnified Party,
which firm shall be designated in writing by the Indemnified Party.
Notwithstanding the foregoing, the Indemnifying Parties shall be prohibited from
confessing or settling any criminal allegations brought against the Indemnified
Party without the express written consent of the Indemnified Party.

             (c) If the Indemnifying Parties fail to notify the Indemnified
Party within the Election Period that the Indemnifying Parties elect to defend
the Indemnified Party pursuant to Section 12.3(b), or if the Indemnifying
Parties elect to defend the Indemnified Party pursuant to Section 12.3(b) but
fail diligently and promptly to prosecute or settle the Third Party Claim, then
the Indemnified Party shall have the right to defend, at the sole cost and
expense of the Indemnifying Parties (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Parties to a final conclusion or settled. The Indemnified
Parties shall have full control of such defense and proceedings, provided,
however, that the Indemnified Parties may not enter into, without the
Indemnifying Parties' consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim. Notwithstanding the
foregoing, if the Indemnifying Parties have delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement and if such
dispute is resolved in favor of the Indemnifying Parties, the Indemnifying
Parties shall not be required to bear the costs and expenses of the Indemnified
Parties' defense pursuant to this paragraph or of the Indemnifying Party's
participation therein at the Indemnified Party's request, and the Indemnified
Party shall reimburse the Indemnifying Parties in full for all costs and
expenses of such litigation. The Indemnifying Parties may participate in, but
not control, any defense or settlement controlled by the Indemnified Party
pursuant to this Section 12.3(c), and the Indemnifying Parties shall bear their
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnifying Parties have been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnified Party, then the Indemnifying Parties may employ
separate counsel and upon written notification thereof, the Indemnified Party
shall not have the right to assume the defense of such action on behalf of the
Indemnifying Parties.

             (d) In the event any Indemnified Party should have a claim against
any Indemnifying Parties hereunder that does not involve a Third Party Claim,
the Indemnified Party shall transmit to the Indemnifying Parties a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Parties do not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Parties dispute such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Parties hereunder. If the Indemnifying Parties have timely disputed such claim,
as provided above, such dispute shall be resolved by the procedures set forth in
Section 12.7.

             (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Agreement relating to a Third Party Claim shall be made within
thirty (30) days after the latest of (i) the settlement of such Third Party
Claim, (ii) the expiration of the period for appeal of a final adjudication



                                       34

<PAGE>   40

of such Third Party Claim, or (iii) the expiration of the period for appeal of a
final adjudication of the Indemnifying Parties liability to the Indemnified
Party under this Agreement. Payments of all amounts owing by the Indemnifying
Parties pursuant to Section 12.3(d) shall be made within thirty (30) days after
the later of (i) the expiration of the 60-day Indemnity Notice period or (ii)
the expiration of the period for appeal of a final adjudication of the
Indemnifying Parties liability to the Indemnified Party under this Agreement.
During the two-year period following the Closing Date, each Seller shall be
entitled to satisfy payments owed to APP by transfer of APP Common Stock from
such Seller to APP. For all purposes of this Agreement, the value of each share
of APP Common Stock transferred to APP pursuant to this Agreement shall be
calculated by averaging the daily closing prices for a share of APP Common Stock
for the twenty (20) consecutive trading days on which such shares are actually
traded on the Nasdaq National Market preceding the date of the Claim Notice. The
number of shares of APP Common Stock permitted to be transferred under this
Section 12.3(e) shall be diminished proportionately in accordance with the
percentage of APP Common Stock released under the Lock-Up Provisions set forth
herein. The rights of any Seller to transfer shares of APP Common Stock in
satisfaction of payments owed to APP pursuant to this Agreement shall terminate
upon the earlier of (x) the termination of the Lock-Up Provisions set forth
herein or (y) at the end of the two-year period following the Closing Date.

             (f) The Indemnifying Parties shall provide the Indemnified Party
with written notice of any firm offer that is made to settle or compromise a
Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Parties notify the Indemnified Party in writing that the Indemnifying Parties
agree to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Parties to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Parties desired to accept such settlement.

             (g) Notwithstanding anything contained in this Agreement to the
contrary, Indemnifying Parties in the aggregate (i) shall have no obligation
hereunder to provide indemnification for the first [$______________] of Damages
(without counting Immaterial Claims as defined below), and (ii) in no event
shall the Indemnifying Parties have any liability hereunder with respect to any
singular incident or a fact involving a breach or inaccuracy of Madison if the
Damages from such claim are equal to or less than [$_____________] ("Immaterial
Claims"). Notwithstanding anything to the contrary contained herein, the
obligations of each Seller hereunder shall not exceed __________ percent
(_____%) of the value of the Exchange Consideration paid to such Seller pursuant
to the Related Acquisition, if any, on the Closing Date.

      Section 12.4 Remedies Exclusive. The remedies provided in this Agreement
are the exclusive rights or remedies available to one party against the other,
either at law or in equity, except in the case of fraud.

      Section 12.5 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

      Section 12.6 Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit



                                       35

<PAGE>   41

received by the party to be indemnified or the net proceeds received by the
party to be indemnified with respect to recovery from third parties or insurance
proceeds, and such correlative insurance benefit shall be net of the insurance
premium, if any, that becomes due as a result of such claim.

      Section 12.7 Dispute Resolution.

             (a) Arbitration. The parties hereto agree that any claim,
controversy, dispute or disagreement between or among any of the parties arising
out of or relating to this Agreement shall be governed exclusively by the terms
and provisions of this Section 12.7; provided, however, that within ten (10)
days from the date which any claim, controversy, dispute or disagreement cannot
be resolved and prior to commencing an arbitration procedure pursuant to this
Section 12.7, the parties shall meet to discuss and consider other alternative
dispute resolution procedures other than arbitration including, but not limited
to, Judicial Arbitration & Mediation Services, Inc., if applicable. If at any
time prior to the rendering of the decision by the arbitrator (or pursuant to
such other alternative dispute resolution procedure) as contemplated in this
Section 12.7 to the extent a party makes a written offer to the other party
proposing a settlement of the matter(s) at issue and such offer is rejected,
then the party rejecting such offer shall be obligated to pay the costs and
expenses (excluding the amount of the award granted under the decision) of the
party that offered the settlement from the date such offer was received by such
other party if the decision is for a dollar amount that is less than the amount
of such offer to settle. Notwithstanding the foregoing, the terms and provisions
of this Section 12.7 shall not preclude any party hereto from seeking, or a
court of competent jurisdiction from granting, a temporary restraining order,
temporary injunction or other equitable relief for any breach of (i) any
noncompetition or confidentiality covenant or (ii) any duty, obligation,
covenant, representation or warranty, the breach of which may cause irreparable
harm or damage.

             (b) Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among the parties hereto arising out of or relating to
this Agreement (including any claim based on or arising from an alleged tort)
and the parties hereto have not reached agreement regarding an alternative to
arbitration, the parties agree to select within thirty (30) days of notice by a
party to the other of its desire to seek arbitration under this Section 12.7 one
(1) arbitrator mutually acceptable to APP and the Sellers to hear and decide all
such claims under this Section 12.7. Each of the arbitrators proposed shall be
impartial and independent of all parties. If the parties cannot agree on the
selection of an arbitrator within said 30-day period, then any party may in
writing request the judge of the United States District Court for the Western
District of Texas senior in term of service to appoint the arbitrator and,
subject to this Section 12.7, such arbitrator shall hear all arbitration matters
arising under this Section 12.7.

             (c) Applicable Rules.

                  (1) Each arbitration hearing shall be held at a place in Boxar
County, Texas acceptable to the arbitrator. The arbitration shall be conducted
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association to the extent such rules do not conflict with the terms hereof;
provided, however, that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including as to rules
of evidence and procedure. The decision of the arbitrator shall be reduced to
writing and shall be binding on the parties and such decision shall contain a
concise statement of the reasons in support of such decision. Judgment upon the
award(s) rendered by the arbitrator may be entered and execution had in any
court of competent jurisdiction or application may be made to such court for a
judicial acceptance of the award and an order of enforcement. The charges and
expenses of the arbitrator shall be shared equally by the parties to the
hearing.

<PAGE>   42

                              (2) The arbitration shall commence within ten (10)
days after the arbitrator is selected in accordance with the provisions of this
Section 12.7. In fulfilling his duties with respect to determining the amount of
any loss, the arbitrator may consider such matters as, in the opinion of the
arbitrator, are necessary or helpful to make a proper valuation. The arbitrator
may consult with and engage disinterested third parties to advise the
arbitrator. The arbitrator shall not add any interest factor reflecting the time
value of money to the amount of any loss and shall not award any punitive
damages.

                        (3) If the arbitrator selected hereunder should die,
resign or be unable to perform his or her duties hereunder, the parties, or such
senior judge (or such judge's successor) in the event the parties cannot agree,
shall select a replacement arbitrator. The procedure set forth in this Section
12.7 for selecting the arbitrator shall be followed from time to time as
necessary.

                        (4) As to any determination of the amount of any loss,
or as to the resolution of any other claim, controversy, dispute or
disagreement, that under the terms hereof is made subject to arbitration, no
lawsuit based on such claimed loss or such resolution shall be instituted by the
parties hereto, other than to compel arbitration proceedings or enforce the
award of the arbitrator, except as otherwise provided in Section 12.7(b).

                        (5) All privileges under Texas and federal law,
including attorney-client and work-product privileges, shall be preserved and
protected to the same extent that such privileges would be protected in a
federal court proceeding applying Texas law.

             (a) at any time prior to the Closing Date by mutual agreement of
all parties;

representation or warranty of any Seller or Madison contained in this Agreement
or in any certificate or other document executed and delivered by any Seller or
Madison pursuant to this Agreement is or becomes untrue or breached in any
material respect or if any Seller or Madison fails to comply in any material
respect with any material covenant or agreement contained herein, and any such
misrepresentation, noncompliance or breach is not cured, waived or eliminated
within thirty (30) days after receipt of written notice thereof;

             (c) at any time prior to the Closing Date by Seller as to Seller if
any representation or warranty of APP contained in this Agreement or in any
certificate or other document executed and delivered by APP pursuant to this
Agreement is or becomes untrue in any material respect of if APP fails to comply
in any material respect with any covenant or agreement contained herein, and any
such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

             (d) at any time prior to the Closing Date by APP if, as a result of
the conduct of due diligence and regulatory compliance procedures, APP deems
termination to be advisable; or

             (e) by APP or Seller as to Seller if the Exchange shall not have
been consummated by September 30, 1997.

      Section 13.2 Effect of Termination. Except as set forth in Section 14.3,
in the event this Agreement is terminated pursuant to this Article XIV, this
Agreement shall forthwith become void.

                                   ARTICLE XIV

                    Nondisclosure of Confidential Information

      Section 14.1 Non-Disclosure Covenant. Seller and Madison recognize and
acknowledge that each has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APP that is
valuable, special and a unique asset of such entity's business. APP acknowledges
that it had in the past, currently has, and in the future may possibly have,
access to certain Confidential Information of Madison that is valuable, special
and a unique asset of each such business. Seller, Madison and APP, severally,
agree that they will not disclose such Confidential Information to any person,
firm, corporation, association or other entity for any purpose or reason
whatsoever, except (a) to authorized representatives of APP, Seller and Madison
and (b) to counsel and other advisers to APP, Sellers and Madison provided that
such advisers (other than counsel) agree to the confidentiality provisions of
this Section 14.1, unless (i) such information becomes available to or known by
the public generally through no fault of Madison, Seller or APP, as the case may
be, (ii) disclosure is required by law or the order of any governmental
authority under color of law, provided, that prior to disclosing any information
pursuant to this clause (ii) Madison, Seller or APP, as the case may be, shall,
if possible, give prior written notice thereof to Madison, Seller or APP and
provide Madison, Seller or APP with the opportunity to contest such disclosure,
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, or
(iv) the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Exchange or otherwise. In the event of a breach
or threatened breach by Seller or Madison, on the one hand, and APP, on the
other hand, of the provisions of this Section, APP, Seller and Madison shall be
entitled to an injunction restraining the other party, as the case may be, from
disclosing, in whole or in part, such Confidential Information. Nothing herein
shall be construed as prohibiting any of such parties from pursuing any other
available remedy for such breach or threatened breach, including the recovery of
damages.

      Section 14.2 Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, APP, Seller and Madison agree that, in the event of a
breach by either of them of the foregoing covenant, the covenant may be enforced
against them by injunctions and restraining orders.

      Section 14.3 Survival. The obligations of the parties under this Article
XIV shall survive the termination of this Agreement.

                                   ARTICLE XV

      Section 15.1 Amendment; Waivers. This Agreement may be amended, modified
or supplemented only by an instrument in writing executed by all the parties
hereto. Any waiver of any terms and conditions hereof must be in writing, and
signed by the parties hereto. The waiver of any of the terms and conditions of
this Agreement shall not be construed as a waiver of any other terms and
conditions hereof.

hereby or in any agreement entered into in connection with the transactions
contemplated hereby shall be assignable by any party hereto, except by APP to a
wholly owned subsidiary of APP; provided that any such assignment shall not
relieve APP of its obligations hereunder.

      Section 15.3 Parties in Interest; No Third Party Beneficiaries. Except as
otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. Except as

contemplated hereby shall be deemed to confer upon any person not a party hereto
or thereto any rights or remedies hereunder or thereunder.

contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

      Section 15.5 Severability. If any provision of this Agreement is held to
be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

      Section 15.6 Survival of Representations, Warranties and Covenants. The
representations, warranties and covenants contained herein shall survive the
Closing and all statements contained in any certificate, exhibit or other
instrument delivered by or on behalf of Madison, Seller or APP pursuant to this
Agreement shall be deemed to have been representations and warranties made by
Madison, Seller and APP, respectively. Notwithstanding any provision in this
Agreement to the contrary, the representations and warranties contained herein
shall survive the Closing until the second anniversary of the Closing Date
except that (a) the representations and warranties set forth in Section 3.20
with respect to environmental matters shall survive for a period of ten (10)

respect to healthcare matters shall survive for a period of six (6) years and

the extent that any party to be indemnified pursuant to such provisions actually
incurs liability under the Securities Act, the Exchange Act or any other federal
or state securities law, the representations and warranties set forth therein
shall survive until the expiration of any applicable limitations period.

      Section 15.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN

(except by written instrument pursuant to Section 16.1 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default in or breach of any of the terms

            Section 3.1 Organization and Good Standing; Qualification. South
Texas is a limited partnership duly organized and validly existing under the
laws of its state of organization, with all requisite power and authority to
own, operate and lease its assets and properties and to carry on its business as
currently conducted. South Texas is in good standing in each jurisdiction where
the character of the property owned or leased by it or the nature of its
activities makes such qualification necessary, except where such failure to be
so qualified or in good standing would not have a Material Adverse Effect on
South Texas. Copies of the Certificate of Limited Partnership and all amendments
thereto of South Texas and the Limited Partnership Agreement of South Texas and
all amendments thereto (the "Partnership Agreement") and copies of the minutes
of South Texas, all of which have been or will be made available to APP for
review, are true and complete as in effect on the date of this Agreement, and in
the case of the minutes, accurately reflect all material proceedings of the
partners of South Texas (and all committees thereof).

            Section 3.2 Authorization and Validity. South Texas has all
requisite right, power and authority to execute, deliver and perform this
Agreement and all agreements and other documents executed and delivered by it
pursuant to this Agreement or to be executed and delivered on the Closing Date,
and has taken all action required by law, its Certificate of Limited
Partnership, its Partnership Agreement or otherwise, to authorize the execution,
delivery and performance of this Agreement and such related documents. Seller
has the legal capacity to enter into and perform this Agreement and the other
agreements to be executed and delivered in connection herewith. This Agreement
and all agreements and documents executed and delivered in connection herewith
have been, or will be as of the Closing Date, duly executed and delivered by
Seller and South Texas and constitute or will constitute the legal, valid and
binding obligations of Seller, enforceable against Seller and South Texas in
accordance with their respective terms, except as may be limited by applicable
bankruptcy, insolvency or similar laws affecting creditors' rights generally or
by general equity principles, or by public policy.

            Section 3.3 Governmental Authorization. Other than consents, filings
or notifications required to be made or obtained solely by APP (including,
without limitation, in connection with the Initial Public Offering, Form S-4 or
any Hart-Scott-Rodino filing to be made by APP, if any), the execution, delivery
and performance by Seller and South Texas of this Agreement and the agreements
provided for herein, and the consummation of the transactions contemplated
hereby and thereby by Seller and South Texas requires no action by or in respect
of, or filing with, any governmental body, agency, official or authority.

            Section 3.4 Capitalization and Title. The Sellers collectively are,

securities laws.

Agreement and any other documents contemplated hereby (with or without the

subject or bound except for such conflict, termination, breach or default, the
occurrence of which would not result in a Material Adverse Effect on South
Texas; and (v) except as contemplated by this Agreement, will not create any

                    (a) suffered any change or changes in its working capital,

Seller and South Texas, South Texas does not have any liabilities or obligations
of any nature, whether accrued, absolute, contingent or otherwise, asserted or
unasserted except for liabilities or obligations reflected in the Disclosure
Schedules.

            Section 3.11 Litigation and Claims. There are no claims, lawsuits,
actions, arbitrations, administrative or other proceedings, governmental
investigations or inquiries pending or, to the knowledge of Seller and South
Texas, threatened against, or affecting South Texas, any Partnership Subsidiary,
or, to the knowledge of Seller and South Texas, any Seller or any other licensed
professional or other individual affiliated with South Texas affecting or that
would reasonably be likely to affect the Partnership Units or the operations,
business condition (financial or otherwise), or results of operations of South
Texas which (i) if successful, may, individually or in the aggregate, have a
Material Adverse Effect on South Texas or (ii) could adversely affect the
ability of South Texas or any Partnership Subsidiary to effect the transactions
contemplated hereby, and to the knowledge of Seller and South Texas there is no
basis for any such action or any state of facts or occurrence of any event which
would reasonably be likely to give rise to the foregoing. There are no
unsatisfied judgments against Seller, South Texas or any Partnership Subsidiary
or any licensed professional or other individual affiliated with South Texas or
any Partnership Subsidiary relating to services provided on behalf of South
Texas or any Partnership Subsidiary or any consent decrees to which any of the
foregoing is subject. Each of the matters, if any, set forth in this Section
3.11 is fully covered by policies of insurance of South Texas or any Partnership
Subsidiary as in effect on the date hereof.

            Section 3.12 No Violation of Law. Neither South Texas nor any
Partnership Subsidiary has been, nor shall be as of the Closing Date (by virtue
of any action, omission to act, contract to which it is a party or any
occurrence or state of facts whatsoever), in violation of any applicable local,
state or



                                        9

<PAGE>   15

federal law, ordinance, regulation, order, injunction or decree, or any other
requirement of any governmental body, agency, authority or court binding on it,
or relating to its properties, assets or business or its advertising, sales or
pricing practices, except for violations which, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
South Texas.

            Section 3.13 Lease Agreements. The Disclosure Schedules contain a
true, accurate and complete list of all the lease agreements and license
agreements to which South Texas or any Partnership Subsidiary is a party and
pursuant to which South Texas or any Partnership Subsidiary leases (whether as
lessor or lessee) or licenses (whether as licensor or licensee) any real or
personal property related to the operation of its business and which requires
payments in excess of $12,000 per year (the "Lease Agreements"). South Texas has
delivered to APP true and complete copies of all of the Lease Agreements. Each
Lease Agreement is valid, effective and in full force in accordance with its
terms, and there is not under any such lease (i) any existing or claimed
material default by South Texas or any Partnership Subsidiary (as applicable) or
event of material default or event which with notice or lapse of time, or both,
would constitute a material default by South Texas or any Partnership Subsidiary
(as applicable) and, individually or in the aggregate, may reasonably result in
a Material Adverse Effect on South Texas, or, (ii) to the knowledge of Seller
and South Texas, any existing material default by any other party under any of
the Lease Agreements or any event of material default or event which with notice
or lapse of time, or both, would constitute a material default by any such
party. To the knowledge of Seller and South Texas, there is no pending or
threatened reassessment of any property covered by the Lease Agreements. To the
extent necessary to accomplish the intent of the Agreement, South Texas or any
Partnership Subsidiary shall use reasonable good faith efforts, and Seller shall
use reasonable good faith efforts to cause South Texas, to obtain prior to the
Closing Date the consent of each landlord or lessor whose consent is required to
the assignment of the Lease Agreements and will use reasonable good faith
efforts to deliver to APP in writing such consents as are necessary to effect a
valid and binding transfer or assignment of South Texas's or any Partnership
Subsidiary's rights thereunder. South Texas has a good, clear, valid and
enforceable leasehold interest under each of the Lease Agreements. The Lease
Agreements comply with the exceptions to ownership interests and compensation
arrangements set out in 42 U.S.C. Section 1395nn, 42 C.F.R. Section 1001.952,
and any similar applicable state law safe harbor or other exemption provisions.

            Section 3.14 Real and Personal Property.

                    (a) Neither South Texas nor each Partnership Subsidiary owns
any interest (other than the Lease Agreements) in real property.

                    (b) South Texas and each Partnership Subsidiary (i) has good
title to all of its properties and assets (real, personal and mixed, tangible
and intangible) and any rights or interests therein which it purports to own;
and (ii) owns such rights, interests, assets and property free and clear of all
Encumbrances, title defects or objections (except for taxes not yet due and
payable). The personal property presently used in connection with the operation
of the business of South Texas and each Partnership Subsidiary constitutes the
necessary personal property assets to continue operation of South Texas and each
Partnership Subsidiary.

            Section 3.15 Indebtedness for Borrowed Money. Except for trade
payables incurred in the ordinary course of business, South Texas does not have
any direct or indirect indebtedness for borrowed money, including indebtedness
by way of lease-purchase arrangements or guarantees, and is not obligated in any
manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

            Section 3.16 Contracts and Commitments.

                    (a) The Disclosure Schedules contain a true, accurate and
complete list, and South Texas has delivered to APP true and complete copies, of
each contract, agreement and other instrument requiring South Texas to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate (other
than insurance contracts identified in Section 3.22 or Lease Agreements
identified in Section 3.13) to which South Texas is a party or by which it or
any of its properties or assets are bound including, without limitation, (i) all
agreements between South Texas, on the one hand, and any government entity,
provider, hospital, health maintenance organization, other managed care
organization or other third-party provider, on the other hand, then in effect
relating to the provision of medical, diagnostic imaging or consulting services,
treatments, patient referrals or other similar activities, (ii) all indentures,
mortgages, notes, loan or credit agreements and other agreements and obligations
relating to the borrowing of money or to the direct or indirect guarantee or
assumption of obligations of third parties requiring South Texas to make, or
setting forth conditions under which South Texas would be required to make,
aggregate future payments in excess of $10,000 in any fiscal year or $25,000 in
the aggregate, (iii) all agreements for capital improvements or acquisitions
involving an amount of $75,000 in any fiscal year or $75,000 in the aggregate,
(iv) all agreements containing a covenant limiting the freedom of South Texas
(or any provider employee of South Texas) to compete in any line of business
with any person or entity or in any geographic area or (v) all written contracts
and commitments providing for future payments by South Texas in excess of
$10,000 in any fiscal year or $25,000 in the aggregate and that are not
cancelable by providing notice of sixty (60) days or less. All such contracts,
agreements or other instruments are in full force and effect, there has been no
threatened cancellation thereof, there are no outstanding disputes thereunder,
each is with unrelated third parties and was entered into on an arms-length
basis in the ordinary course of business and, assuming the receipt of the
appropriate consents, all will continue to be binding in accordance with their
terms after consummation of the transaction contemplated herein; there are no
contracts, agreements or other instruments to which South Texas is a party or is
bound (other than physician employment contracts and insurance policies) which
could either singularly or in the aggregate have a Material Adverse Effect on
the value to APP of the assets and properties to be acquired by APP from South
Texas, or which could inhibit or prevent South Texas from transferring to or
vesting in APP good and sufficient title to the assets and properties to be
acquired by APP except where the failure to transfer would not have a Material
Adverse Effect on APP. In every instance where consent is necessary, on or
before the Closing Date South Texas shall use reasonable good faith efforts, and
Seller shall use reasonable good faith efforts to cause South Texas, to obtain
and deliver to APP in writing, effective as of the Closing Date, such consents
as are necessary to enable APP to enjoy all of the rights now enjoyed by South
Texas under such contracts. Any and all such consents shall be in a form
reasonably acceptable to APP and shall contain an acknowledgment by the
consenting party that South Texas has fully complied with and is not in default
under any provision of the particular contract or agreement.

                    (b) (i) Neither South Texas nor Seller has received notice
of any plan or intention of any other party to exercise any right to cancel or
terminate any contract, agreement or instrument, and to the knowledge of South
Texas and Seller there are no facts that would justify the exercise of such a
right; and (ii) neither South Texas nor Seller currently contemplates, or has
reason to believe any other Person currently contemplates, any amendment or
change to any such contract, agreement or instrument.

            Section 3.17 Employee Matters. South Texas does not have any
employees and is not currently a party to any employment contract (except for
oral employment agreements which are terminable at will), consulting or
collective bargaining contracts, deferred compensation, pension plan (as defined
in Section 3(2) of the Employee Retirement Income Security Act of 1974, as
amended, and all rules and regulations from time to time promulgated thereunder
("ERISA")), profit sharing, bonus or other nonqualified benefit or compensation
commitments, benefit plans, arrangements or plans (whether written



                                       11

<PAGE>   17

or oral), including all welfare plans (as defined in Section 3(1) of ERISA) of
or pertaining to South Texas and any of its present or former employees, or any
predecessors in interest.

            Section 3.18 Labor Relations. Intentionally omitted.

            Section 3.19 Employee Benefit Plans. Intentionally omitted.

            Section 3.20 Environmental Matters.

                    (a) Neither South Texas nor any Partnership Subsidiary has,
within the five (5) years preceding the date hereof, through the Closing Date,
received from any federal, state or local governmental body, agency, authority
or entity, or any other Person, any written notice, demand, citation, summons,
complaint or order or any notice of any penalty, lien or assessment, and to the
knowledge of Seller and South Texas no investigation or review is pending by any
governmental entity, with respect to any (i) alleged violation by South Texas of
any Environmental Law (as defined in subsection (e) below) (ii) alleged failure
by South Texas to have any environmental permit, certificate, license, approval,
registration or authorization required pursuant to any Environmental Law in
connection with the conduct of its business; or (iii) alleged illegal Regulated
Activity (as defined in subsection (e) below) by South Texas.

                    (b) Neither South Texas nor any Partnership Subsidiary has
used, transported, disposed of or arranged for the disposal of (as those terms
are defined in and construed under the Comprehensive Environmental Response,
Compensation and Liability Act) any Hazardous Substance that would be reasonably
likely to give rise to any Environmental Liabilities for South Texas under any
applicable Environmental Law that had, or would reasonably be likely to have, a
Material Adverse Effect on South Texas. Neither South Texas nor any Partnership
Subsidiary has engaged in any activity or failed to undertake any activity which
action or failure to act has given, or would reasonably be likely to give, rise
to any Environmental Liabilities or enforcement action by any federal, state or
local regulatory agency or authority, or has resulted, or would reasonably be
likely to result, in any fine or penalty imposed pursuant to any Environmental
Law. The Disclosure Schedules disclose any known presence of asbestos in or on
South Texas's or any Partnership Subsidiary's owned or leased premises. To the
knowledge of Seller and South Texas, there is no friable asbestos in or on South
Texas's or any Partnership Subsidiary's owned or leased premises.

                    (c) To the knowledge of Seller and South Texas, no soil or
water in or under any assets currently or formerly held for use or sale by South
Texas or any Partnership Subsidiary is or has been contaminated by any Hazardous
Substance while such assets or premises were owned, leased, operated or managed,
directly or indirectly by South Texas or any Partnership Subsidiary, where such
contamination had, or would be reasonably likely to have, a Material Adverse
Effect on South Texas.

                    (d) There have been no environmental audits and other
similar reports which have been prepared by, for or, to the knowledge of Seller
and South Texas, concerning South Texas or any Partnership Subsidiary within the
five (5) years preceding the date hereof through the Closing Date with respect
to any real property now or previously owned or leased by South Texas, any
Partnership Subsidiary or any of its predecessors, true and complete copies of
which have been provided to APP.

                    (e) For the purposes of this Section 3.20(e), the following

            local laws, ordinances, codes, regulations, rules, policies and
            orders (including without limitation, Medical Waste Laws) that are
            intended to assure the protection of the environment, or that
            classify, regulate, call for the remediation of, require reporting
            with respect to, or list or define air, water, groundwater, solid
            waste, hazardous, toxic, or radioactive substances, materials,
            wastes, pollutants or contaminants, or which are intended to assure
            the safety of employees, workers or other persons, including the
            public in each case as in effect on the date hereof.

                        "Environmental Liabilities" shall mean all liabilities
            of the Company or any Company Subsidiary, whether contingent or
            fixed, which (i) have arisen, or would reasonably be likely to
            arise, under Environmental Laws and (ii) relate to actions occurring
            or conditions existing on or prior to the date hereof or the Closing
            Date.

                        "Hazardous Substances" shall mean any toxic or hazardous
            substances, material or waste, including Medical Waste, or any
            pollutant or contaminant, or infectious or radioactive substance or

            and wastes defined in or regulated under any Environmental Laws.

                        "Regulated Activity" shall mean any generation,
            treatment, storage, recycling, transportation, disposal or release
            of any Hazardous Substances.

            Section 3.21 Filing Reports. All returns, reports, plans and filings
of any kind or nature necessary to be filed by South Texas with any governmental
agency or authority have been properly completed and timely filed in compliance
with all applicable requirements, except where failure to so file would not have
a Material Adverse Effect on South Texas.

            Section 3.22 Insurance Policies. The Disclosure Schedules list and
briefly describe South Texas's policies of insurance to which South Texas or any
Partnership Subsidiary is a party or under which South Texas or any Partnership
Subsidiary, officer or director thereof is or has been covered at any time
during the last five (5) years preceding the date of this Agreement relating to
the business of South Texas or any Partnership Subsidiary (the "Insurance
Policies"). All of the Insurance Policies are valid, outstanding and enforceable
policies, except as may be limited by applicable bankruptcy, insolvency or
similar laws affecting creditors' rights generally or the availability of
equitable remedies and all premiums with respect thereto which are due and
payable are currently paid. All Insurance Policies currently maintained by South
Texas or any Partnership Subsidiary ("Current Policies") taken together, (i)
provide adequate insurance coverage for the assets, properties and operations of
South Texas and its Affiliates for all risks normally insured against by a
Person carrying on a substantially similar business or businesses as South Texas
and its Affiliates, (ii) are sufficient for compliance with legal and
contractual requirements to which South Texas or any of its Affiliates is a
party or by which any of them may be bound, and (iii) shall be maintained in
force (including the payment of all premiums and compliance with their terms)
without interruption up to and including the Closing Date. True, complete and
correct copies of all Insurance Policies have been provided to APP. Neither
South Texas nor any Partnership Subsidiary nor any officer or partner thereof
has received any notice or other written communication from any issuer of any
Current Policy cancelling such policy, materially increasing any deductibles or
retained amounts thereunder, or materially increasing the annual or other
premiums payable thereunder and, to the knowledge of Seller and South Texas, no
such cancellation or increase of deductibles, retainages or premiums is
threatened. There are no outstanding claims, settlements or premiums owed
against any Insurance Policy, and all required notices have been given and all
known potential or actual claims under any Insurance Policy have been presented
in due and timely fashion. Within the five (5) years preceding the Agreement,
neither South Texas nor any Partnership Subsidiary has filed a written
application for any



                                       13

professional liability insurance coverage which has been denied by an insurance
agency or carrier. The Disclosure Schedules also set forth a list of all claims

Texas or any Partnership Subsidiary during the immediately preceding three-year
period.

            Section 3.23 Accounts Receivable. The Disclosure Schedules set forth
a list and aging of all accounts receivable of South Texas as of March 31, 1997,
which list is complete, true and accurate in all material respects. All such
accounts receivable arose in the ordinary course of business and have not been
previously written off as bad debts and, are, to the extent still uncollected,
to the knowledge of Seller and South Texas collectible in the ordinary course of
business, net of reserves for doubtful and uncollectible accounts shown on the
accounting records of South Texas (which reserves are adequate and calculated
consistent with past practice).

            Section 3.24 Accounts Payable; Suppliers.

                    (a) The Disclosure Schedules set forth a true and complete
(i) list of the accounts payable of South Texas as of March 31, 1997, and (ii)
list of each individual indebtedness owned by South Texas of $5,000 or more,
setting forth the payee and the amount of indebtedness.

                    (b) The Disclosure Schedules set forth a true, correct and
complete list of the names and addresses of each of the providers/suppliers of
products or services to South Texas (including, without limitation all providers
of care to patients) which accounted for a dollar volume of purchases paid for
by South Texas in excess of $25,000 for the fiscal year ended [DECEMBER 31,
1996], or which is reasonably expected to account for a dollar volume of
purchases paid for by South Texas in excess of $25,000 for the fiscal year to
end [DECEMBER 31, 1997].

            Section 3.25 Inventory. All items of inventory on hand on the date
of this Agreement consist, and all such items on hand on the Closing Date will
consist, net of all applicable reserves with respect thereto (calculated
consistent with past practice), of items of a quality and a quantity usable and
saleable in the ordinary course of South Texas's business and conform to
generally accepted standards in the industry of which South Texas is a part.
Purchase commitments of South Texas for inventory are not materially in excess
of normal requirements, and none of such purchase commitments are at prices in
excess of prevailing market prices at the time of such purchase commitment.

            Section 3.26 Licenses, Authorization and Provider Programs.

                    (a) South Texas and each other licensed employee or
contractor of South Texas (i) is the holder of all valid licenses, approvals,
orders, consents, permits, registrations, qualifications and other rights and
authorizations required by law, ordinance, regulation or ruling of any
governmental regulatory authority necessary to operate his/her/its business and
(ii) is eligible to participate in and to receive reimbursement under Titles
XVIII and XIX of the Social Security Act (the "Medicare and Medicaid Programs")
and any other programs funded in whole or in part by federal, state or local
entities for which South Texas is eligible ("Governmental Programs"). Each of
South Texas and Seller has a current provider number for such Governmental
Programs and with such private non-governmental programs (including without
limitation any private insurance program) under which South Texas is presently
receiving payments directly or indirectly from any Payor for technical imaging
services provided by any licensed technician or contractor of South Texas (such
non-governmental programs herein referred to as "Private Programs"). A true,
correct and complete list of such licenses, permits and other authorizations
(including, but not limited to verification of Medicare and Medicaid provider
numbers and participating physician contracts under 1842(h) of the Social
Security Act) and provider

agreements is set forth in the Disclosure Schedules, true, complete and correct
copies of which have been provided to APP. No violation, default, order or
deficiency exists with respect to any of the items listed in the Disclosure
Schedules except for such violations, defaults, orders or deficiencies which
would not be reasonably likely to have a Material Adverse Effect on South Texas,
and there is no action pending or to the knowledge of Seller and South Texas
recommended by any state or federal agencies having jurisdiction over the items
listed in the Disclosure Schedules, either to revoke, withdraw or suspend any
material license or to terminate the participation of South Texas in any
Governmental Program or Private Program, and no event has occurred which, with
or without notice or lapse of time, or both, would constitute grounds for a
violation, order or deficiency with respect to any of the items listed in the
Disclosure Schedules to revoke, withdraw or suspend any material license to
operate its business as is presently being conducted by it. To the knowledge of
Seller and South Texas, there has been no decision not to renew any existing
agreement with any provider or Payor relating to South Texas's business as

            As inducement to each Seller and South Texas to enter into this
Agreement, APP represents and warrants to each Seller and South Texas both as of
the date hereof and as of the Closing Date as set forth below, subject to those
exceptions set forth in the Disclosure Schedules attached hereto and
incorporated herein by this reference, specifically identifying the relevant
subparagraphs hereof, which exceptions shall be deemed to be representations and
warranties as if made hereunder.

corporation duly organized, validly existing and in good standing under the laws
of the state of Delaware, with all requisite corporate power and authority to
own, operate and lease its assets and properties and to carry on its business as
currently conducted. APP is duly qualified to do business as a foreign
corporation and is in good standing in each jurisdiction where the character of
the property owned or leased by it or the nature of its activities makes such
qualification necessary, except where such failure to be so qualified or in good
standing would not have a Material Adverse Effect on APP. Copies of the
certificate of incorporation and all amendments thereto of APP and the bylaws of
APP, as amended, and copies of the corporate minutes of APP regarding the
transactions contemplated hereby, all of which have been or will be made
available to Sellers and South Texas for review, are true, correct and complete
as in effect on the date of this Agreement and accurately reflect all material
proceedings of the stockholders and directors of APP (and all committees
thereof) regarding the transactions contemplated hereby. The stock record books
of APP, which have been or will be made available to Sellers and South Texas for
review, contain true, complete and accurate records of the stock ownership of
APP and the transfer of the shares of its capital stock.

            Section 4.2 Authorization and Validity. APP has all requisite
corporate power to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution, delivery and performance by APP
of this Agreement, the agreements provided for herein and the Other Agreements,
and the consummation by APP of the transactions contemplated hereby and thereby
are within APP's corporate powers and have been duly authorized by all necessary
action on the part of APP's Board of Directors. This Agreement and the Other
Agreements have been duly executed by APP. This Agreement and all other
agreements and obligations entered into and undertaken in connection with the
transactions contemplated hereby to which APP is a party constitute, or upon
execution will constitute, valid and binding agreements of APP, enforceable
against it in accordance with their respective terms, except as may be limited
by bankruptcy or other laws affecting creditors' rights generally, or by general
equity principles, or by public policy.

            Section 4.3 Governmental Authorization. Other than consents, filings
or notifications required to be made or obtained solely by South Texas, the
execution, delivery and performance by APP of this Agreement and the agreements
provided for herein, and the consummation of the transactions contemplated
hereby and thereby by APP requires no action by or in respect of, or filing
with, any governmental body, agency, official or authority.

            Section 4.4 Capitalization. The authorized capital stock of APP
consists of 20,000,000 shares of APP Common Stock, of which 2,000,000 shares are
issued and outstanding and 10,000,000 shares of APP Preferred Stock, none of
which are outstanding. Each outstanding share of APP Common Stock has been
legally and validly issued and is fully paid and nonassessable, and was issued
pursuant to a valid exemption from registration under (i) the Securities Act,
and (ii) all applicable state securities laws. No shares of capital stock are
owned by APP in treasury. No shares of capital stock of APP have been



                                       18

issued or disposed of in violation of the preemptive rights, rights of first
refusal or similar rights of any stockholders of APP. APP has no bonds,
debentures, notes or other obligations the holders of which have the right to
vote (or are convertible into or exercisable for securities having the right to
vote) with the stockholders of APP on any matter. There exist no options,
warrants, subscriptions, calls, commitments or other rights to purchase, or
securities convertible into or exchangeable for, any of the authorized or
outstanding securities of APP and no option, warrant, subscription, call, or
commitment or commission right of any kind exists which obligates APP to issue
any of its authorized but unissued capital stock. APP has no obligation
(contingent or otherwise) to purchase, redeem or otherwise acquire any of its
equity securities or any interests therein or to pay any dividend or make any
distribution in respect thereof.

            Section 4.5 Subsidiaries and Investments. APP does not own, directly
or indirectly, any capital stock or other equity, ownership or proprietary
interest in any corporation, partnership, association, trust, joint venture or
other entity (the "APP Subsidiaries").

            Section 4.6 Absence of Conflicting Agreements or Required Consents.
The execution, delivery and performance of this Agreement by APP and any other
documents contemplated hereby (with or without the giving of notice, the lapse
of time, or both): (i) does not require the consent of any governmental or
regulatory body or authority or any other third party except for such consents,
for which the failure to obtain would not result in a Material Adverse Effect on
APP; (ii) will not conflict with any provision of APP's Certificate of
Incorporation or Bylaws; (iii) will not conflict with, result in a violation of,
or constitute a default under any law, ordinance, regulation, ruling, judgment,
order or injunction of any court or governmental instrumentality to which APP is
a party or by which APP or its properties are subject or bound; (iv) will not
conflict with, constitute grounds for termination of, result in a breach of,
constitute a default under, require any notice under, or accelerate or permit
the acceleration of any performance required by the terms of any agreement,
instrument, license or permit, material to this transaction, to which APP is a
party or by which APP or any of its properties are bound except for such
conflict, termination, breach or default, the occurrence of which would not
result in a Material Adverse Effect on APP; and (v) will not create any
Encumbrance or restriction upon APP Common Stock or any of the assets or
properties of APP. The financial statements of APP contained in the Registration

accounting principles consistently applied (except as may be indicated therein
or in the notes thereto), (b) present fairly the financial position of APP and
APP Subsidiaries as of the dates indicated and present fairly the results of

any applicable local, state or federal law, ordinance, regulation, order,
injunction or decree, or any other requirement of any governmental body, agency
or authority or court binding on it, or relating to its property or business or

            APP agrees that between the date hereof and the Closing:

            Section 6.1 Consummation of Agreement. APP will take all action
reasonably necessary to cause the consummation of the transactions contemplated

            (a) South Texas shall cooperate with APP to promptly prepare and

appropriate Forms) to be filed by APP in connection with its Initial Public
Offering and offering of the shares of APP Common Stock to the Target Interest
Holders pursuant to the transactions contemplated by this Agreement and the
Other Agreements (including the prospectus constituting parts thereof, the

<PAGE>   32

Seller and South Texas specifically for inclusion in the Registration
Statements, by exhibit or otherwise and (ii) in the case of APP, will, at the
time the Registration Statements and each amendment and supplement thereto, if
any, becomes effective under the Securities Act, none of them contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading. Seller and South Texas
shall be entitled to review the Registration Statements and each of the
amendments thereto, if any, prior to the time each becomes effective under the
Securities Act. Seller and South Texas shall have no responsibility for
information contained in the Registration Statements except for information
provided by Seller or South Texas specifically for inclusion therein. Seller's

otherwise affect the representations, covenants and warranties of APP contained
in this Agreement.

            (c) Seller and South Texas shall, upon request, furnish APP with all

that would have been or would be required to be set forth or described in the

covenant of such party contained herein; provided that no amendment or
supplement to a Schedule that constitutes or reflects a Material Adverse Effect
on South Texas may be made unless APP consents to such amendment or supplement,
and no amendment or supplement to a Schedule that constitutes or reflects a
Material Adverse Effect on APP may be made unless Sellers and South Texas
consent to such amendment or supplement. For purposes of this Agreement,
including without limitation for purposes of determining whether the conditions
set forth in Sections 8.1 and 9.1 have been fulfilled, the Disclosure Schedules
hereto shall be deemed to be the Disclosure Schedules as amended or supplemented
pursuant to this Section 7.2. In the event that Sellers or South Texas seek to
amend or supplement a Disclosure Schedule pursuant to this Section 7.2 and APP
does not consent to such amendment or supplement, or APP seeks to amend or
supplement a Disclosure Schedule pursuant to this Section 7.2, and Seller and
South Texas do not consent, this Agreement shall be deemed terminated by mutual
consent as set forth in Section 13.1(a) hereof.

            Section 7.3 Actions Contrary to Stated Intent. No party hereto will
knowingly, either before or after the Closing Date, take any action that would

of Section 351 of the Code.

the foregoing shall not apply to any disclosure by APP in any filing with the
DOJ, FTC or SEC.

            Section 7.5 Expenses. Each party to this Agreement shall be solely
responsible for their own fees and expenses with respect to the transactions
contemplated herein including, without limitation, the fees charged by
attorneys, accountants and financial advisors retained by such parties. The fees

expenses incurred by Seller and South Texas shall be paid by Seller in full
immediately prior to the Closing.

            Section 7.6 Registration Statements. APP shall prepare and file the

efforts to cause the Registration Statements to become effective under the
Securities Act and take any action required to be taken under the applicable
state "Blue Sky" or other securities laws in connection with the issuance of the

Closing Date, of the Secretary of State of Delaware establishing that APP is in
existence, has paid all franchise or similar taxes, if any, and otherwise is in
good standing to transact business in the state of Delaware;

                    (h) such other instrument or instruments of transfer
prepared by Seller or South Texas as shall be necessary or appropriate, as
Seller or South Texas or his/her/its respective counsel shall reasonably
request, to carry out and effect the purpose and intent of this Agreement.

                                   ARTICLE XI

                              Post Closing Matters

            Section 11.1 Further Instruments of Transfer. Following the Closing,
at the request of APP and at APP's sole cost and expense, Seller and South Texas
shall deliver any further instruments of transfer and take all reasonable action
as may be necessary or appropriate to carry out the purpose and intent of this
Agreement.

            Section 11.2 Exchange Tax Covenant.

                    (a) The parties intend that the Exchange will qualify as a
tax-free transaction within the meaning of Section 351 of the Code in which the
Company will not recognize gain or loss, and pursuant to which any gain
recognized by Seller as a result of the Exchange will not exceed the amount of
any cash received by a Seller in the Exchange (a "Reorganization").

                    (b) Both prior to and after the Closing Date, all books and
records shall be maintained, and all Tax Returns and schedules thereto shall be
filed in a manner consistent with the Exchange being treated as a
Reorganization. These obligations are excused as to a party required to maintain
the books or file a Tax Return if such party has provided to the other parties a
written opinion of competent tax counsel to the effect that there is not
substantial authority, within the meaning of Section 6662(d)(2)(B)(i) of the
Code, to report the Exchange as a Reorganization and such opinion either is
furnished prior to the Closing Date or is based on facts or events not known at
the Closing Date. Each party shall provide to each other party such tax
information, reports, returns, or schedules as may be reasonably required to
assist such party in accounting for and reporting the Exchange as a
Reorganization.

                    (c) APP shall cause the requirements of Rule 144(c) under
the Securities Act to be met with respect to APP for so long as those
requirements must be met to enable sales by the Sellers who are affiliates of
South Texas to meet the requirements of Rule 145(d) under the Securities Act.

                                   ARTICLE XII

                                    Remedies

            Section 12.1 Indemnification by Sellers. Subject to the terms,
limitations and conditions of this Agreement, Sellers (each an "Indemnifying
Party" and collectively, the "Indemnifying Parties"), severally, agree to
indemnify, defend and hold APP and its directors, officers, employees, agents,
attorneys, consultants and Affiliates (each an "Indemnified Party" and
collectively, the "Indemnified Parties"), harmless from and against all losses,
claims, obligations, demands, assessments, penalties, liabilities, costs,
damages, reasonable attorneys' fees and expenses (including, without limitation,
all costs of experts and all costs incidental to or in connection with any
appellate process) (collectively, "Damages") asserted against or incurred by an
Indemnified Party arising out of or resulting from:

                    (a) a breach of any representation, warranty or covenant of
any Seller or South Texas contained in this Agreement (without giving effect to
any Material Adverse Effect qualifier contained as



                                       32

<PAGE>   38

part of any such representation or warranty or covenant contained in this
Agreement or in any Schedule or certificate delivered hereunder);

                    (b) any violation (or alleged violation) by any Seller or
South Texas and/or any of its past or present directors, officers, partners,
employees, agents, attorneys, consultants and Affiliates of any state or federal
law governing health care fraud and abuse or prohibition on referral of patients
to Persons in which a licensed professional has a financial or other form of
interest (including, but not limited to, fraud and abuse in the Medicare and
Medicaid Programs) occurring on or before the Closing Date; and

                    (c) any liability under the Securities Act, the Exchange Act
or any other federal or state "Blue Sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any (i) untrue statement
of a material fact in any Registration Statement or any prospectus forming a
part thereof, or any amendment thereof or supplement thereto relating to South
Texas (including any Partnership Subsidiary) or (ii) failure to state
information necessary to make the statements required to be stated therein not
misleading arising (in the case of either (i) or (ii)) solely from information
provided in writing to APP or its counsel by South Texas or any Seller or their
agents specifically for inclusion in any such Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto (including, without limitation, schedules, exhibits and certifications
delivered by South Texas or any of its agents in connection with this
Agreement).

            Notwithstanding anything herein to the contrary, nothing contained
in this Agreement shall relieve any Seller or South Texas of any liability or
limit any liability that he, she or it may have in the case of fraud in
connection with the transactions contemplated by this Agreement.

            Section 12.2 Indemnification by APP. Subject to the terms,
limitations and conditions of this Agreement, APP (an "Indemnifying Party")
hereby agrees to indemnify, defend and hold the Sellers, and, as applicable,
their respective directors, partners, officers, stockholders, employees, agents,
attorneys, consultants and Affiliates (each an "Indemnified Party") and
collectively, the "Indemnified Parties") harmless from and against all Damages
asserted against or incurred by such individuals and/or entities arising out of
or resulting from:

                    (a) a breach by APP of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of APP contained in
this Agreement or in any schedule or certificate delivered hereunder; and

                    (b) any liability under the Securities Act, the Exchange Act
or any other federal or state "Blue Sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any (i) untrue statements
of a material fact in any Registration Statement or any prospectus forming a
part thereof, or any amendment thereof or supplement thereto or (ii) failure to
state information necessary to make the statements required to be stated therein
not misleading (except for any liability based upon any actual or alleged untrue
statement of material fact or an omission to state a material fact relating to
South Texas or any Seller which was derived from any information provided in
writing by the Company or a Company Subsidiary or any of their agents contained
in the representations and warranties set forth in this Agreement or any
certificate, exhibit, schedule or instrument required to be delivered under this
Agreement.)

            Notwithstanding anything herein to the contrary, nothing contained
in this Agreement shall relieve APP of any liability or limit any liability that
it may have in the case of fraud in connection with the transactions
contemplated by this Agreement.

            Section 12.3 Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                    (a) The Indemnified Party shall promptly (and, in any event,
at least ten (10) days prior to the due date for any responsive pleadings,
filings or other documents) (i) notify each Indemnifying Party of any
third-party claim or claims asserted against the Indemnified Party ("Third Party
Claim") that could give rise to a right of indemnification under this Agreement
and (ii) transmit to the Indemnifying Parties a written notice ("Claim Notice")
describing in reasonable detail the nature of the Third Party Claim, a copy of
all papers served with respect to such claim (if any), an estimate of the amount
of Damages attributable to the Third Party Claim and the basis of the
Indemnified Party's request for indemnification under this Agreement. The
failure to promptly deliver a Claim Notice shall not relieve any Indemnifying
Party of its obligations to any Indemnified Party with respect to the related
Third Party Claim except to the extent that the resulting delay is materially
prejudicial to the defense of such claim. Within thirty (30) days after receipt
of any Claim Notice (the "Election Period"), the Indemnifying Parties shall
notify the Indemnified Party (x) whether the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement with respect
to such Third Party Claim and (y) whether the Indemnifying Parties desire, at
the sole cost and expense of each Indemnifying Party, to defend the Indemnified
Party against such Third Party Claim.

                    (b) If the Indemnifying Parties notify the Indemnified Party
within the Election Period that the Indemnifying Parties elect to assume the
defense of the Third Party Claim, then the Indemnifying Parties shall have the
right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party or Indemnified Parties, such Third Party
Claim by all appropriate proceedings, which proceedings shall be prosecuted
diligently by the Indemnifying Parties to a final conclusion or settled at the
discretion of the Indemnifying Parties in accordance with this Section 12.3(b).
Except as set forth in Section 12.3(f) below, the Indemnifying Parties shall
have full control of such defense and proceedings, including any compromise or
settlement thereof. The Indemnified Party is hereby authorized, at the sole cost
and expense of the Indemnifying Parties (but only if the Indemnified Party is
entitled to indemnification hereunder), to file, during the Election Period, any
motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Parties and not prejudicial to the Indemnifying Parties. If requested by the
Indemnifying Parties, the Indemnified Party agrees, at the sole cost and expense
of the Indemnifying Parties, to cooperate with the Indemnifying Parties and
their counsel in contesting any Third Party Claim that the Indemnifying Parties
elect to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person. The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Parties pursuant to this Section 12.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Parties and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Parties, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Parties, and upon written
notification thereof, the Indemnifying Parties shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Parties shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party. Notwithstanding the foregoing, the
Indemnifying Parties shall be prohibited from confessing or settling any
criminal



                                       34

<PAGE>   40

allegations brought against the Indemnified Party without the express written
consent of the Indemnified Party.

                    (c) If the Indemnifying Parties fail to notify the
Indemnified Party within the Election Period that the Indemnifying Parties elect
to defend the Indemnified Party pursuant to Section 12.3(b), or if the
Indemnifying Parties elect to defend the Indemnified Party pursuant to Section
12.3(b) but fail diligently and promptly to prosecute or settle the Third Party
Claim, then the Indemnified Party shall have the right to defend, at the sole
cost and expense of the Indemnifying Parties (if the Indemnified Party is
entitled to indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Parties to a final conclusion or settled. The Indemnified
Parties shall have full control of such defense and proceedings, provided,
however, that the Indemnified Parties may not enter into, without the
Indemnifying Parties' consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim. Notwithstanding the
foregoing, if the Indemnifying Parties have delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement and if such
dispute is resolved in favor of the Indemnifying Parties, the Indemnifying
Parties shall not be required to bear the costs and expenses of the Indemnified
Parties' defense pursuant to this paragraph or of the Indemnifying Party's
participation therein at the Indemnified Party's request, and the Indemnified
Party shall reimburse the Indemnifying Parties in full for all costs and
expenses of such litigation. The Indemnifying Parties may participate in, but
not control, any defense or settlement controlled by the Indemnified Party
pursuant to this Section 12.3(c), and the Indemnifying Parties shall bear their
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnifying Parties have been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnified Party, then the Indemnifying Parties may employ
separate counsel and upon written notification thereof, the Indemnified Party
shall not have the right to assume the defense of such action on behalf of the
Indemnifying Parties.

                    (d) In the event any Indemnified Party should have a claim
against any Indemnifying Parties hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Parties a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification under
this Agreement. If the Indemnifying Parties do not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Parties dispute such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Parties hereunder. If the Indemnifying Parties have timely disputed such claim,
as provided above, such dispute shall be resolved by the procedures set forth in
Section 12.7.

                    (e) Payments of all amounts owing by any Indemnifying Party
pursuant to this Agreement relating to a Third Party Claim shall be made within
thirty (30) days after the latest of (i) the settlement of such Third Party
Claim, (ii) the expiration of the period for appeal of a final adjudication of
such Third Party Claim, or (iii) the expiration of the period for appeal of a
final adjudication of the Indemnifying Parties liability to the Indemnified
Party under this Agreement. Payments of all amounts owing by the Indemnifying
Parties pursuant to Section 12.3(d) shall be made within thirty (30) days after
the later of (i) the expiration of the 60-day Indemnity Notice period or (ii)
the expiration of the period for appeal of a final adjudication of the
Indemnifying Parties liability to the Indemnified Party under this Agreement.
During the two-year period following the Closing Date, each Seller shall be
entitled to satisfy payments owed to APP by transfer of APP Common Stock from
such Seller to APP. For all



                                       35

<PAGE>   41

purposes of this Agreement, the value of each share of APP Common Stock
transferred to APP pursuant to this Agreement shall be calculated by averaging
the daily closing prices for a share of APP Common Stock for the twenty (20)
consecutive trading days on which such shares are actually traded on the Nasdaq
National Market preceding the date of the Claim Notice. The number of shares of
APP Common Stock permitted to be transferred under this Section 12.3(e) shall be
diminished proportionately in accordance with the percentage of APP Common Stock
released under the Lock-Up Provisions set forth herein. The rights of any Seller
to transfer shares of APP Common Stock in satisfaction of payments owed to APP
pursuant to this Agreement shall terminate upon the earlier of (x) the
termination of the Lock-Up Provisions set forth herein or (y) at the end of the
two-year period following the Closing Date.

                    (f) The Indemnifying Parties shall provide the Indemnified
Party with written notice of any firm offer that is made to settle or compromise
a Third Party Claim against an Indemnified Party. If a firm offer is made to
settle such a claim solely by the payment of money damages and the Indemnifying
Parties notify the Indemnified Party in writing that the Indemnifying Parties
agree to such settlement, but the Indemnified Party elects not to accept and
agree to it, the Indemnified Party may continue to contest or defend such Third
Party Claim and, in such event, the total maximum liability of the Indemnifying
Parties to indemnify or otherwise reimburse the Indemnified Party hereunder with
respect to such a claim shall be limited to and shall not exceed the amount of
such settlement offer, plus reasonable out-of-pocket costs and reasonable
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnifying Parties desired to accept such settlement.

                    (g) Notwithstanding anything contained in this Agreement to
the contrary, Indemnifying Parties in the aggregate (i) shall have no obligation
hereunder to provide indemnification for the first [$_______] of Damages
(without counting Immaterial Claims as defined below), and (ii) in no event
shall the Indemnifying Parties have any liability hereunder with respect to any
singular incident or a fact involving a breach or inaccuracy of South Texas if
the Damages from such claim are equal to or less than [$_______] ("Immaterial
Claims"). Notwithstanding anything to the contrary contained herein, the
obligations of each Seller hereunder shall not exceed the value of the Exchange
Consideration paid to such Seller pursuant to the Related Acquisition, if any,
on the Closing Date.

            Section 12.4 Remedies Exclusive. The remedies provided in this
Agreement are the exclusive remedies available to one party against the other,
either at law or in equity, except in the case of fraud.

            Section 12.5 Costs, Expenses and Legal Fees. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

            Section 12.6 Tax Benefits; Insurance Proceeds. The total amount of
any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

            Section 12.7 Dispute Resolution.

                    (a) Arbitration. The parties hereto agree that any claim,
controversy, dispute or disagreement between or among any of the parties arising
out of or relating to this Agreement shall be governed exclusively by the terms
and provisions of this Section 12.7; provided, however, that within ten (10)
days from the date which any claim, controversy, dispute or disagreement cannot
be resolved and prior to commencing an arbitration procedure pursuant to this
Section 12.7, the parties shall meet to discuss and consider other alternative
dispute resolution procedures other than arbitration including, but not limited
to, Judicial Arbitration & Mediation Services, Inc., if applicable. If at any
time prior to the rendering of the decision by the arbitrator (or pursuant to
such other alternative dispute resolution procedure) as contemplated in this
Section 12.7 to the extent a party makes a written offer to the other party
proposing a settlement of the matter(s) at issue and such offer is rejected,
then the party rejecting such offer shall be obligated to pay the costs and
expenses (excluding the amount of the award granted under the decision) of the
party that offered the settlement from the date such offer was received by such
other party if the decision is for a dollar amount that is less than the amount
of such offer to settle. Notwithstanding the foregoing, the terms and provisions
of this Section 12.7 shall not preclude any party hereto from seeking, or a
court of competent jurisdiction from granting, a temporary restraining order,
temporary injunction or other equitable relief for any breach of (i) any
noncompetition or confidentiality covenant or (ii) any duty, obligation,
covenant, representation or warranty, the breach of which may cause irreparable
harm or damage.

                    (b) Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among the parties hereto arising out of or relating to
this Agreement (including any claim based on or arising from an alleged tort)
and the parties hereto have not reached agreement regarding an alternative to
arbitration, the parties agree to select within thirty (30) days of notice by a
party to the other of its desire to seek arbitration under this Section 12.7 one
(1) arbitrator mutually acceptable to APP and the Sellers to hear and decide all
such claims under this Section 12.7. Each of the arbitrators proposed shall be
impartial and independent of all parties. If the parties cannot agree on the
selection of an arbitrator within said 30-day period, then any party may in
writing request the judge of the United States District Court for the Western
District of Texas senior in term of service to appoint the arbitrator and,
subject to this Section 12.7, such arbitrator shall hear all arbitration matters
arising under this Section 12.7.

                    (c) Applicable Rules.

                        (1) Each arbitration hearing shall be held at a place in
Boxar County, Texas acceptable to the arbitrator. The arbitration shall be
conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof; provided, however, that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including as to rules
of evidence and procedure. The decision of the arbitrator shall be reduced to
writing and shall be binding on the parties and such decision shall contain a
concise statement of the reasons in support of such decision. Judgment upon the
award(s) rendered by the arbitrator may be entered and execution had in any
court of competent jurisdiction or application may be made to such court for a
judicial acceptance of the award and an order of enforcement. The charges and
expenses of the arbitrator shall be shared equally by the parties to the
hearing.

                        (2) The arbitration shall commence within ten (10) days
after the arbitrator is selected in accordance with the provisions of this
Section 12.7. In fulfilling his duties with respect to determining the amount of
any loss, the arbitrator may consider such matters as, in the opinion of the
arbitrator, are necessary or helpful to make a proper valuation. The arbitrator
may consult with and



                                       37

<PAGE>   43

engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

                        (3) If the arbitrator selected hereunder should die,
resign or be unable to perform his or her duties hereunder, the parties, or such
senior judge (or such judge's successor) in the event the parties cannot agree,
shall select a replacement arbitrator. The procedure set forth in this Section
12.7 for selecting the arbitrator shall be followed from time to time as
necessary.

                        (4) As to any determination of the amount of any loss,
or as to the resolution of any other claim, controversy, dispute or
disagreement, that under the terms hereof is made subject to arbitration, no
lawsuit based on such claimed loss or such resolution shall be instituted by the
parties hereto, other than to compel arbitration proceedings or enforce the
award of the arbitrator, except as otherwise provided in Section 12.7(b).

                        (5) All privileges under Texas and federal law,
including attorney-client and work-product privileges, shall be preserved and
protected to the same extent that such privileges would be protected in a
federal court proceeding applying Texas law.

                                   Termination

agreement of all parties;

                    (b) at any time prior to the Closing Date by APP if any
material representation or warranty of any Seller or South Texas contained in
this Agreement or in any certificate or other document executed and delivered by
any Seller or South Texas pursuant to this Agreement is or becomes untrue or
breached in any material respect or if any Seller or South Texas fails to comply
in any material respect with any material covenant or agreement contained
herein, and any such misrepresentation, noncompliance or breach is not cured,
waived or eliminated within thirty (30) days after receipt of written notice
thereof;

                    (c) at any time prior to the Closing Date by Seller as to
Seller if any representation or warranty of APP contained in this Agreement or
in any certificate or other document executed and delivered by APP pursuant to
this Agreement is or becomes untrue in any material respect of if APP fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

                    (d) at any time prior to the Closing Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures, APP
deems termination to be advisable; or

                    (e) by APP or Seller as to Seller if the Exchange shall not
have been consummated by September 30, 1997.

            Section 13.2 Effect of Termination. Except as set forth in Section
14.3, in the event this Agreement is terminated pursuant to this Article XIV,
this Agreement shall forthwith become void.

                    Nondisclosure of Confidential Information

            Section 14.1 Non-Disclosure Covenant. Seller and South Texas
recognize and acknowledge that each has in the past, currently has, and in the
future may possibly have, access to certain Confidential Information of APP that
is valuable, special and a unique asset of such entity's business. APP
acknowledges that it had in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of South Texas that is
valuable, special and a unique asset of each such business. Seller, South Texas
and APP, severally, agree that they will not disclose such Confidential
Information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
APP, Seller and South Texas and (b) to counsel and other advisers to APP,
Sellers and South Texas provided that such advisers (other than counsel) agree
to the confidentiality provisions of this Section 14.1, unless (i) such
information becomes available to or known by the public generally through no
fault of South Texas, Seller or APP, as the case may be, (ii) disclosure is
required by law or the order of any governmental authority under color of law,
provided, that prior to disclosing any information pursuant to this clause (ii)
South Texas, Seller or APP, as the case may be, shall, if possible, give prior
written notice thereof to South Texas, Seller or APP and provide South Texas,
Seller or APP with the opportunity to contest such disclosure, (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, or (iv)
the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Exchange or otherwise. In the event of a breach
or threatened breach by Seller or South Texas, on the one hand, and APP, on the
other hand, of the provisions of this Section, APP, Seller and South Texas shall
be entitled to an injunction restraining the other party, as the case may be,
from disclosing, in whole or in part, such Confidential Information. Nothing
herein shall be construed as prohibiting any of such parties from pursuing any
other available remedy for such breach or threatened breach, including the
recovery of damages.

            Section 14.2 Damages. Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, Seller and South Texas agree
that, in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

            Section 14.3 Survival. The obligations of the parties under this
Article XIV shall survive the termination of this Agreement.

                                  Miscellaneous

            Section 15.1 Amendment; Waivers. This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto. Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto. The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

            Section 15.2 Assignment. Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any

party hereto, except by APP to a wholly owned subsidiary of APP; provided that
any such assignment shall not relieve APP of its obligations hereunder.

Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto. Except as
otherwise provided herein, neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party hereto

contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

            Section 15.5 Severability. If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

            Section 15.6 Survival of Representations, Warranties and Covenants.
The representations, warranties and covenants contained herein shall survive the
Closing and all statements contained in any certificate, exhibit or other
instrument delivered by or on behalf of South Texas, Seller or APP pursuant to

by South Texas, Seller and APP, respectively. Notwithstanding any provision in
this Agreement to the contrary, the representations and warranties contained
herein shall survive the Closing until the second anniversary of the Closing
Date except that (a) the representations and warranties set forth in Section
3.20 with respect to environmental matters shall survive for a period of ten

(d) solely for purposes of Section 12.1(c) and Section 12.2(b), and solely to
the extent that any party to be indemnified pursuant to such provisions actually
incurs liability under the Securities Act, the Exchange Act or any other federal
or state securities law, the representations and warranties set forth therein
shall survive until the expiration of any applicable limitations period.

            Section 15.7 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF TEXAS.

            Section 15.8 Captions. The captions in this Agreement are for

(except by written instrument pursuant to Section 16.1 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy

the exercise of any other right, power or privilege. Except as set forth herein,
no remedy set forth in this Agreement or otherwise conferred upon or reserved to
any party shall be considered exclusive of any other remedy available to any
party, but the same shall be distinct, separate and cumulative and may be
exercised from time to time as often as occasion may arise or as may be deemed
expedient.

documents.  Seller has the legal capacity to enter into and perform this
Agreement and the other agreements to be executed and delivered in connection
herewith.  This Agreement and all agreements and documents executed and
delivered in connection herewith have been, or will be as of the Closing Date,

except as may be limited by applicable bankruptcy, insolvency or similar laws
affecting creditors' rights generally or by general equity principles, or by
public policy.

         Section 3.3      Governmental Authorization.  Other than consents,
filings or notifications required to be made or obtained solely by APP
(including, without limitation, in connection with the Initial Public Offering,
Form S-4 or any Hart-Scott-Rodino filing to be made by APP, if any), the
execution, delivery and performance by Seller and San Antonio of this Agreement
and the agreements provided for herein, and the consummation of the
transactions contemplated hereby and thereby by Seller and San Antonio requires
no action by or in respect of, or filing with, any governmental body, agency,
official or authority.

a valid exemption from registration under (i) the Securities Act and (ii) all
applicable state securities laws.

redeem or otherwise acquire any of its partnership interests or to pay any

structure of San Antonio nor the relative ownership of partnership interests
among any of its partners has been altered or changed in contemplation of the
Exchange within the two (2) years preceding the date of this Agreement.

         Section 3.6      Continuity of Business Enterprise.  There has not

this Agreement and any other documents contemplated hereby (with or without the

of any governmental or regulatory body or authority or any other third party

Seller and San Antonio, San Antonio does not have any liabilities or
obligations of any nature, whether accrued, absolute, contingent or otherwise,
asserted or unasserted except for liabilities or obligations reflected in the
Disclosure Schedules.

         Section 3.11     Litigation and Claims.  There are no claims,
lawsuits, actions, arbitrations, administrative or other proceedings,
governmental investigations or inquiries pending or, to the knowledge of Seller
and San Antonio, threatened against, or affecting San Antonio, any Partnership
Subsidiary, or, to the knowledge of Seller and San Antonio, any Seller or any
other licensed professional or other individual affiliated with San Antonio
affecting or that would reasonably be likely to affect the Partnership Units or
the operations, business condition (financial or otherwise), or results of
operations of San Antonio which (i) if successful, may, individually or in the
aggregate, have a Material Adverse Effect on San Antonio or (ii) could
adversely affect the ability of San Antonio or any Partnership Subsidiary to
effect the transactions contemplated hereby, and to the knowledge of Seller and
San Antonio there is no basis for any such action or any state of facts or
occurrence of any event which would reasonably be likely to give rise to the
foregoing.  There are no unsatisfied judgments against Seller, San Antonio or
any Partnership Subsidiary or any licensed professional or other individual
affiliated with San Antonio or any Partnership Subsidiary relating to services
provided on behalf of San Antonio or any Partnership Subsidiary or any consent
decrees to which any of the foregoing is subject.  Each of the matters, if any,
set forth in this Section 3.11 is fully covered by policies of insurance of San
Antonio or any Partnership Subsidiary as in effect on the date hereof.

         Section 3.12     No Violation of Law.  Neither San Antonio nor any
Partnership Subsidiary has been, nor shall be as of the Closing Date (by virtue
of any action, omission to act, contract to which it is a party or any
occurrence or state of facts whatsoever), in violation of any applicable local,
state or federal law, ordinance, regulation, order, injunction or decree, or
any other requirement of any governmental body, agency, authority or court
binding on it, or relating to its properties, assets or business or its
advertising, sales or pricing practices, except for violations which,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on San Antonio.

         Section 3.13     Lease Agreements.  The Disclosure Schedules contain a
true, accurate and complete list of all the lease agreements and license
agreements to which San Antonio or any Partnership Subsidiary is a party and
pursuant to which San Antonio or any Partnership Subsidiary leases (whether as
lessor or lessee) or licenses (whether as licensor or licensee) any real or
personal property related to the operation of its business and which requires
payments in excess of $12,000 per year (the "Lease Agreements").  San Antonio
has delivered to APP true and complete copies of all of the Lease Agreements.
Each Lease Agreement is valid, effective and in full force in accordance with
its terms, and there is not under any such lease (i) any existing or claimed
material default by San Antonio or any Partnership Subsidiary (as applicable)
or event of material default or event which with notice or lapse of time, or
both, would constitute a material default by San Antonio or any Partnership
Subsidiary (as applicable) and, individually or in the aggregate, may
reasonably result in a Material Adverse Effect on San Antonio, or, (ii) to the
knowledge of Seller and San Antonio, any existing material default by any other
party under any of the Lease Agreements or any event of material default or
event which with notice or lapse of time, or both, would constitute a material
default by any such party.  To the knowledge of Seller and San Antonio, there
is no pending or threatened reassessment of any property covered by the Lease
Agreements.  To the extent necessary to accomplish the intent of the Agreement,
San Antonio or any Partnership Subsidiary shall use reasonable good faith
efforts, and Seller shall use reasonable good faith efforts to cause San
Antonio, to obtain prior to the Closing Date the consent of each landlord or
lessor whose consent is required to the assignment of the Lease Agreements and
will use reasonable good faith efforts to deliver to APP in writing such
consents as are necessary to effect a valid and binding transfer or assignment
of San Antonio's or any Partnership Subsidiary's rights thereunder.  San
Antonio has a good, clear, valid and enforceable leasehold interest under each
of the Lease Agreements.  The Lease Agreements comply with the exceptions to
ownership interests and compensation arrangements set out in 42 U.S.C. Section
1395nn, 42 C.F.R. Section  1001.952, and any similar applicable state law safe
harbor or other exemption provisions.

         Section 3.14     Real and Personal Property.

                 (a)      Neither San Antonio nor each Partnership Subsidiary
owns any interest (other than the Lease Agreements) in real property.

                 (b)      San Antonio and each Partnership Subsidiary (i) has
good title to all of its properties and assets (real, personal and mixed,
tangible and intangible) and any rights or interests therein which it purports
to own; and (ii) owns such rights, interests, assets and property free and
clear of all Encumbrances, title defects or objections (except for taxes not
yet due and payable).  The personal property presently used in connection with
the operation of the business of San Antonio and each Partnership Subsidiary
constitutes the necessary personal property assets to continue operation of San
Antonio and each Partnership Subsidiary.

         Section 3.15     Indebtedness for Borrowed Money.  Except for trade
payables incurred in the ordinary course of business, San Antonio does not have
any direct or indirect indebtedness for borrowed money, including indebtedness
by way of lease-purchase arrangements or guarantees, and is not obligated in
any manner (actual or contingent) to assume or guarantee any indebtedness or
obligation of another Person.

         Section 3.16     Contracts and Commitments.

                 (a)      The Disclosure Schedules contain a true, accurate and
complete list, and San Antonio has delivered to APP true and complete copies,
of each contract, agreement and other instrument requiring San Antonio to make
future payments of $10,000 in any fiscal year or $25,000 in the aggregate
(other than insurance contracts identified in Section 3.22 or Lease Agreements
identified in Section 3.13) to which San Antonio is a party or by which it or
any of its properties or assets are bound including, without limitation, (i)
all agreements between San Antonio, on the one hand, and any government entity,
provider, hospital, health maintenance organization, other managed care
organization or other third-party provider, on the other hand, then in effect
relating to the provision of medical, diagnostic imaging or consulting
services, treatments, patient referrals or other similar activities, (ii) all
indentures, mortgages, notes, loan or credit agreements and other agreements
and obligations relating to the borrowing of money or to the direct or indirect
guarantee or assumption of obligations of third parties requiring San Antonio
to make, or setting forth conditions under which San Antonio would be required
to make, aggregate future payments in excess of $10,000 in any fiscal year or
$25,000 in the aggregate, (iii) all agreements for capital improvements or
acquisitions involving an amount of $75,000 in any fiscal year or $75,000 in
the aggregate, (iv) all agreements containing a covenant limiting the freedom
of San Antonio (or any provider employee of San Antonio) to compete in any line
of business with any person or entity or in any geographic area or (v) all
written contracts and commitments providing for future payments by San Antonio
in excess of $10,000 in any fiscal year or $25,000 in the aggregate and that
are not cancelable by providing notice of sixty (60) days or less.  All such
contracts, agreements or other instruments are in full force and effect, there
has been no threatened cancellation thereof, there are no outstanding disputes
thereunder, each is with unrelated third parties and was entered into on an
arms-length basis in the ordinary course of business and, assuming the receipt
of the appropriate consents, all will continue to be binding in accordance with
their terms after consummation of the transaction contemplated herein; there
are no contracts, agreements or other instruments to which San Antonio is a
party or is bound (other than physician employment contracts and insurance
policies) which could either singularly or in the aggregate have a Material
Adverse Effect on the value to APP of the assets and properties to be acquired
by APP from San Antonio, or which could inhibit or prevent San Antonio from
transferring to or vesting in APP good and sufficient title to the assets and
properties to be acquired by APP except where the failure to transfer would not
have a Material Adverse Effect on APP.  In every instance where consent is
necessary, on or before the Closing Date San Antonio shall use reasonable good
faith efforts, and Seller shall use reasonable good faith efforts to cause San
Antonio, to obtain and deliver to APP in writing, effective as of the Closing
Date, such consents as are necessary to enable APP to enjoy all of the rights
now enjoyed by San Antonio under such contracts.  Any and all such consents
shall be in a form reasonably acceptable to APP and shall contain an
acknowledgment by the consenting party that San Antonio has fully complied with
and is not in default under any provision of the particular contract or
agreement.

                 (b)      (i)  Neither San Antonio nor Seller has received
notice of any plan or intention of any other party to exercise any right to
cancel or terminate any contract, agreement or instrument, and to the knowledge
of San Antonio and Seller there are no facts that would justify the exercise of
such a right; and (ii) neither San Antonio nor Seller currently contemplates,
or has reason to believe any other Person currently contemplates, any amendment
or change to any such contract, agreement or instrument.

         Section 3.17     Employee Matters.  San Antonio does not have
employees and is not currently a party to any employment contract (except for
oral employment agreements which are terminable at will), consulting or
collective bargaining contracts, deferred compensation, pension plan (as
defined in Section 3(2) of the Employee Retirement Income Security Act of 1974,
as amended, and all rules and regulations from time to time promulgated
thereunder ("ERISA")), profit sharing, bonus or other





                                       11
<PAGE>   17
nonqualified benefit or compensation commitments, benefit plans, arrangements
or plans (whether written or oral), including all welfare plans (as defined in
Section 3(1) of ERISA) of or pertaining to San Antonio and any of its present
or former employees, or any predecessors in interest.

         Section 3.18     Labor Relations.  Intentionally omitted.

         Section 3.19     Employee Benefit Plans.  Intentionally omitted.

         Section 3.20     Environmental Matters.

                 (a)      Neither San Antonio nor any Partnership Subsidiary
has, within the five (5) years preceding the date hereof, through the Closing
Date, received from any federal, state or local governmental body, agency,
authority or entity, or any other Person, any written notice, demand, citation,
summons, complaint or order or any notice of any penalty, lien or assessment,
and to the knowledge of Seller and San Antonio no investigation or review is
pending by any governmental entity, with respect to any (i) alleged violation
by San Antonio of any Environmental Law (as defined in subsection (e) below)
(ii) alleged failure by San Antonio to have any environmental permit,
certificate, license, approval, registration or authorization required pursuant
to any Environmental Law in connection with the conduct of its business; or
(iii) alleged illegal Regulated Activity (as defined in subsection (e) below)
by San Antonio.

                 (b)      Neither San Antonio nor any Partnership Subsidiary
has used, transported, disposed of or arranged for the disposal of (as those
terms are defined in and construed under the Comprehensive Environmental
Response, Compensation and Liability Act) any Hazardous Substance that would be
reasonably likely to give rise to any Environmental Liabilities for San Antonio
under any applicable Environmental Law that had, or would reasonably be likely
to have, a Material Adverse Effect on San Antonio.  Neither San Antonio nor any
Partnership Subsidiary has engaged in any activity or failed to undertake any
activity which action or failure to act has given, or would reasonably be
likely to give, rise to any Environmental Liabilities or enforcement action by
any federal, state or local regulatory agency or authority, or has resulted, or
would reasonably be likely to result, in any fine or penalty imposed pursuant
to any Environmental Law.  The Disclosure Schedules disclose any known presence
of asbestos in or on San Antonio's or any Partnership Subsidiary's owned or
leased premises.  To the knowledge of Seller and San Antonio, there is no
friable asbestos in or on San Antonio's or any Partnership Subsidiary's owned
or leased premises.

                 (c)      To the knowledge of Seller and San Antonio, no soil

San Antonio or any Partnership Subsidiary is or has been contaminated by any
Hazardous Substance while such assets or premises were owned, leased, operated
or managed, directly or indirectly by San Antonio or any Partnership
Subsidiary, where such contamination had, or would be reasonably likely to
have, a Material Adverse Effect on San Antonio.

                 (d)      There have been no environmental audits and other
similar reports which have been prepared by, for or, to the knowledge of Seller
and San Antonio, concerning San Antonio or any Partnership Subsidiary within
the five (5) years preceding the date hereof through the Closing Date with
respect to any real property now or previously owned or leased by San Antonio,
any Partnership Subsidiary or any of its predecessors, true and complete copies
of which have been provided to APP.

following terms have the following meanings:

         laws, ordinances, codes, regulations, rules, policies and orders
         (including without limitation, Medical Waste Laws) that are intended
         to assure the protection of the environment, or that classify,
         regulate, call for the remediation of, require reporting with respect
         to, or list or define air, water, groundwater, solid waste, hazardous,
         toxic, or radioactive substances, materials, wastes, pollutants or
         contaminants, or which are intended to assure the safety of employees,
         workers or other persons, including the public in each case as in
         effect on the date hereof.

                 "Environmental Liabilities" shall mean all liabilities of the
         Company or any Company Subsidiary, whether contingent or fixed, which

         existing on or prior to the date hereof or the Closing Date.

                 "Hazardous Substances" shall mean any toxic or hazardous
         substances, material or waste, including Medical Waste, or any

         and wastes defined in or regulated under any Environmental Laws.

                 "Regulated Activity" shall mean any generation, treatment,
         storage, recycling, transportation, disposal or release of any

         Section 3.21     Filing Reports.  All returns, reports, plans and
filings of any kind or nature necessary to be filed by San Antonio with any
governmental agency or authority have been properly completed and timely filed
in compliance with all applicable requirements, except where failure to so file
would not have a Material Adverse Effect on San Antonio.

         Section 3.22     Insurance Policies.  The Disclosure Schedules list
and briefly describe San Antonio's policies of insurance to which San Antonio
or any Partnership Subsidiary is a party or under which San Antonio or any
Partnership Subsidiary, officer or director thereof is or has been covered at
any time during the last five (5) years preceding the date of this Agreement
relating to the business of San Antonio or any Partnership Subsidiary (the
"Insurance Policies").  All of the Insurance Policies are valid, outstanding
and enforceable policies, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies and all premiums with respect thereto which
are due and payable are currently paid.  All Insurance Policies currently
maintained by San Antonio or any Partnership Subsidiary ("Current Policies")
taken together, (i) provide adequate insurance coverage for the assets,
properties and operations of San Antonio and its Affiliates for all risks
normally insured against by a Person carrying on a substantially similar
business or businesses as San Antonio and its Affiliates, (ii) are sufficient
for compliance with legal and contractual requirements to which San Antonio or
any of its Affiliates is a party or by which any of them may be bound, and
(iii) shall be maintained in force (including the payment of all premiums and
compliance with their terms) without interruption up to and including the
Closing Date.  True, complete and correct copies of all Insurance Policies have
been provided to APP.  Neither San Antonio nor any Partnership Subsidiary nor
any officer or partner thereof has received any notice or other written
communication from any issuer of any Current Policy cancelling such policy,
materially increasing any deductibles or retained amounts thereunder, or
materially increasing the annual or other premiums payable thereunder and, to
the knowledge of Seller and San Antonio, no such cancellation or increase of
deductibles, retainages or premiums is threatened.  There are no outstanding
claims, settlements or premiums owed against any Insurance Policy, and all
required notices have been given and all known potential or actual claims under
any Insurance Policy have been presented in due and timely fashion.  Within the
five (5) years preceding the Agreement, neither San Antonio nor any Partnership
Subsidiary has filed a written application for any





                                       13

professional liability insurance coverage which has been denied by an insurance

All such accounts receivable arose in the ordinary course of business and have
not been previously written off as bad debts and, are, to the extent still
uncollected, to the knowledge of Seller and San Antonio collectible in the
ordinary course of business, net of reserves for doubtful and uncollectible
accounts shown on the accounting records of San Antonio (which reserves are
adequate and calculated consistent with past practice).

         Section 3.24     Accounts Payable; Suppliers.

                 (a)      The Disclosure Schedules set forth a true and

more, setting forth the payee and the amount of indebtedness.

                 (b)      The Disclosure Schedules set forth a true, correct
and complete list of the names and addresses of each of the providers/suppliers
of products or services to San Antonio (including, without limitation all
providers of care to patients) which accounted for a dollar volume of purchases
paid for by San Antonio in excess of $25,000 for the fiscal year ended
[DECEMBER 31, 1996], or which is reasonably expected to account for a dollar
volume of purchases paid for by San Antonio in excess of $25,000 for the fiscal
year to end [DECEMBER 31, 1997].

         Section 3.25     Inventory.  All items of inventory on hand on the
date of this Agreement consist, and all such items on hand on the Closing Date
will consist, net of all applicable reserves with respect thereto (calculated
consistent with past practice), of items of a quality and a quantity usable and
saleable in the ordinary course of San Antonio's business and conform to
generally accepted standards in the industry of which San Antonio is a part.
Purchase commitments of San Antonio for inventory are not materially in excess
of normal requirements, and none of such purchase commitments are at prices in
excess of prevailing market prices at the time of such purchase commitment.

         Section 3.26     Licenses, Authorization and Provider Programs.

                 (a)      San Antonio and each other licensed employee or
contractor of San Antonio (i) is the holder of all valid licenses, approvals,

(ii) is eligible to participate in and to receive reimbursement under Titles
XVIII and XIX of the Social Security Act (the "Medicare and Medicaid Programs")
and any other programs funded in whole or in part by federal, state or local

San Antonio and Seller has a current provider number for such Governmental
Programs and with such private non-governmental programs (including without
limitation any private insurance program) under which San Antonio is presently
receiving payments directly or indirectly from any Payor for technical imaging
services provided by any licensed technician or contractor of San Antonio (such
non-governmental programs herein referred to as "Private Programs").  A true,
correct and complete list of such licenses, permits and other authorizations
(including, but not limited to verification of Medicare and Medicaid provider
numbers and participating physician contracts under 1842(h) of the Social
Security Act) and provider

agreements is set forth in the Disclosure Schedules, true, complete and correct
copies of which have been provided to APP.  No violation, default, order or
deficiency exists with respect to any of the items listed in the Disclosure
Schedules except for such violations, defaults, orders or deficiencies which
would not be reasonably likely to have a Material Adverse Effect on San
Antonio, and there is no action pending or to the knowledge of Seller and San
Antonio recommended by any state or federal agencies having jurisdiction over
the items listed in the Disclosure Schedules, either to revoke, withdraw or
suspend any material license or to terminate the participation of San Antonio
in any Governmental Program or Private Program, and no event has occurred
which, with or without notice or lapse of time, or both, would constitute
grounds for a violation, order or deficiency with respect to any of the items
listed in the Disclosure Schedules to revoke, withdraw or suspend any material
license to operate its business as is presently being conducted by it.  To the
knowledge of Seller and San Antonio, there has been no decision not to renew
any existing agreement with any provider or Payor relating to San Antonio's
business as presently being conducted by it.  San Antonio (i) has not had its
professional license, Drug Enforcement Agency number, Medicare/Medicaid
provider status or staff privileges at any hospital or diagnostic imaging
center suspended, relinquished, terminated or revoked (including orders that
have been entered by any such entities but stayed), (ii) has not been

agency, regulatory body or authority, hospital, Payor or specialty board

state authority that could result in any demand or reimbursement under the
Medicare, Medicaid or Government Programs or any exclusion or which monetary
penalty under federal or state law or (iv) has had a final judgment or
settlement entered against it in connection with a malpractice or similar
action.

                 (b)      San Antonio is not required, or for the 72-month
period prior to the Closing Date was not required, to file any cost reports or
other reports with any Governmental Program or Private Program.

         Section 3.27     Inspections and Investigations.  Neither the right of
San Antonio, nor the right of any licensed professional or other individual
affiliated with San Antonio to receive reimbursements pursuant to any
Governmental Program or Private Program has been terminated or otherwise
materially and adversely affected as a result of any investigation or action
whether by any federal or state governmental regulatory authority or other
third party.  No licensed professional or other individual affiliated with the
business has, during the past three (3) years prior to the Closing Date, had
their professional license or staff privileges limited, suspended or revoked by
any governmental regulatory authority or agency, hospital, integrated delivery
system, trade association, professional review organization, accrediting
organization or certifying agency (including orders that have been entered by
any such entities but stayed).  True, correct and complete copies of all
reports, correspondence, notices and other documents relating to any matter
described or referenced in this Section 3.27 have been provided to APP.

Partnership Subsidiary and (v) other similar agreements relating to the
foregoing to which San Antonio or any Partnership Subsidiary is a party

Rights").

                 (b)      The Disclosure Schedules contain a complete and
accurate list and summary description of all agreements relating to technology,
trade secrets, know-how or processes that San Antonio is licensed or authorized
to use by others (other than technology, know-how or processes generally
available to other health care providers) or which it licenses or authorizes
others to use, true, correct and complete copies of which have been provided to
APP.  There are no outstanding and, to the knowledge of Seller and San Antonio,
any threatened disputes or disagreements with respect to any such agreement.

                 (c)      San Antonio owns or has the legal right to use the
Proprietary Rights without conflicting with, infringing or violating the rights
of any other Person.  No consent of any person will be required for the use
thereof by APP upon consummation of the transactions contemplated hereby and
the Proprietary Rights are freely transferable.  To the knowledge of Seller and
San Antonio, no claim has been asserted by any person to the ownership of or
for infringement by San Antonio of any Proprietary Right of any other Person,
and neither San Antonio nor Seller is aware of any valid basis for any such
claim.  To the best knowledge of Seller and San Antonio, no proceedings have
been threatened which challenge the Proprietary Rights of San Antonio.  San
Antonio has the right to use, free and clear of any adverse claims or rights of
others, all trade secrets, customer lists and proprietary information required
for the performance and marketing of all medical services.

                 (a)      Filing of Tax Returns.  San Antonio has duly and
timely filed (in accordance with any extensions duly granted by the appropriate
governmental agency, if applicable) with the appropriate governmental agencies
all Tax Returns and reports required to be filed with the United States or any
state or any political subdivision thereof or any foreign jurisdiction.  All
such Tax Returns or reports are complete and accurate in all material respects
and properly reflect the taxes of San Antonio for the periods covered thereby.

                 (b)      All Withholding Requirements Satisfied.  All monies
required to be withheld by San Antonio and paid to governmental agencies for
all income, social security, unemployment insurance, sales, excise, use, and
other taxes have been collected or withheld and paid to the respective
governmental agencies.

                 (c)      Safe Harbor Lease.  None of the properties or assets
of San Antonio constitutes property that San Antonio, APP, or any Affiliate of
APP, will be required to treat as being owned by another person pursuant to the
"Safe Harbor Lease" provisions of Section 168(f)(8) of the Code prior to repeal
by the Tax Equity and Fiscal Responsibility Act of 1982.

                 (d)      Tax Exempt Entity.  None of the assets or properties
of San Antonio are subject to a lease to a "tax exempt entity" as such term is
defined in Section 168(h)(2) of the Code.

                     Representations and Warranties of APP

         As inducement to each Seller and San Antonio to enter into this
Agreement, APP represents and warrants to each Seller and San Antonio both as
of the date hereof and as of the Closing Date as set forth below, subject to
those exceptions set forth in the Disclosure Schedules attached hereto and
incorporated herein by this reference, specifically identifying the relevant
subparagraphs hereof, which exceptions shall be deemed to be representations
and warranties as if made hereunder.

         Section 4.1      Organization and Good Standing; Qualification.  APP
is a corporation duly organized, validly existing and in good standing under
the laws of the state of Delaware, with all requisite corporate power and
authority to own, operate and lease its assets and properties and to carry on
its business as currently conducted.  APP is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, except where such failure to be so
qualified or in good standing would not have a Material Adverse Effect on APP.
Copies of the certificate of incorporation and all amendments thereto of APP
and the bylaws of APP, as amended, and copies of the corporate minutes of APP
regarding the transactions contemplated hereby, all of which have been or will
be made available to Sellers and San Antonio for review, are true, correct and
complete as in effect on the date of this Agreement and accurately reflect all
material proceedings of the stockholders and directors of APP (and all
committees thereof) regarding the transactions contemplated hereby.  The stock
record books of APP, which have been or will be made available to Sellers and
San Antonio for review, contain true, complete and accurate records of the
stock ownership of APP and the transfer of the shares of its capital stock.

         Section 4.2      Authorization and Validity.  APP has all requisite
corporate power to execute and deliver this Agreement and to consummate the
transactions contemplated hereby.  The execution, delivery and performance by
APP of this Agreement, the agreements provided for herein and the Other
Agreements, and the consummation by APP of the transactions contemplated hereby
and thereby are within APP's corporate powers and have been duly authorized by
all necessary action on the part of APP's Board of Directors.  This Agreement
and the Other Agreements have been duly executed by APP.  This Agreement and
all other agreements and obligations entered into and undertaken in connection
with the transactions contemplated hereby to which APP is a party constitute,
or upon execution will constitute, valid and binding agreements of APP,
enforceable against it in accordance with their respective terms, except as may
be limited by bankruptcy or other laws affecting creditors' rights generally,
or by general equity principles, or by public policy.

         Section 4.3      Governmental Authorization.  Other than consents,
filings or notifications required to be made or obtained solely by San Antonio,
the execution, delivery and performance by APP of this Agreement and the
agreements provided for herein, and the consummation of the transactions
contemplated hereby and thereby by APP requires no action by or in respect of,
or filing with, any governmental body, agency, official or authority.

         Section 4.4      Capitalization.  The authorized capital stock of APP
consists of 20,000,000 shares of APP Common Stock, of which 2,000,000 shares
are issued and outstanding and 10,000,000 shares of APP Preferred Stock, none
of which are outstanding.  Each outstanding share of APP Common Stock has been
legally and validly issued and is fully paid and nonassessable, and was issued
pursuant to a valid exemption from registration under (i) the Securities Act,
and (ii) all applicable state securities laws.  No shares of capital stock are
owned by APP in treasury.  No shares of capital stock of APP have been

issued or disposed of in violation of the preemptive rights, rights of first
refusal or similar rights of any stockholders of APP.  APP has no bonds,
debentures, notes or other obligations the holders of which have the right to
vote (or are convertible into or exercisable for securities having the right to
vote) with the stockholders of APP on any matter.  There exist no options,
warrants, subscriptions, calls, commitments or other rights to purchase, or
securities convertible into or exchangeable for, any of the authorized or
outstanding securities of APP and no option, warrant, subscription, call, or
commitment or commission right of any kind exists which obligates APP to issue
any of its authorized but unissued capital stock.  APP has no obligation
(contingent or otherwise) to purchase, redeem or otherwise acquire any of its
equity securities or any interests therein or to pay any dividend or make any
distribution in respect thereof.

         Section 4.5      Subsidiaries and Investments.  APP does not own,
directly or indirectly, any capital stock or other equity, ownership or
proprietary interest in any corporation, partnership, association, trust, joint
venture or other entity (the "APP Subsidiaries").

         Section 4.6      Absence of Conflicting Agreements or Required
Consents.  The execution, delivery and performance of this Agreement by APP and
any other documents contemplated hereby (with or without the giving of notice,
the lapse of time, or both): (i) does not require the consent of any
governmental or regulatory body or authority or any other third party except
for such consents, for which the failure to obtain would not result in a
Material Adverse Effect on APP; (ii) will not conflict with any provision of
APP's Certificate of Incorporation or Bylaws; (iii) will not conflict with,
result in a violation of, or constitute a default under any law, ordinance,
regulation, ruling, judgment, order or injunction of any court or governmental
instrumentality to which APP is a party or by which APP or its properties are
subject or bound; (iv) will not conflict with, constitute grounds for
termination of, result in a breach of, constitute a default under, require any
notice under, or accelerate or permit the acceleration of any performance
required by the terms of any agreement, instrument, license or permit, material
to this transaction, to which APP is a party or by which APP or any of its
properties are bound except for such conflict, termination, breach or default,
the occurrence of which would not result in a Material Adverse Effect on APP;
and (v) will not create any Encumbrance or restriction upon APP Common Stock or
any of the assets or properties of APP.  The financial statements of APP
contained in the Registration Statements (a) have been prepared in accordance
with generally accepted accounting principles consistently applied (except as
may be indicated therein or in the notes thereto), (b) present fairly the
financial position of APP and APP Subsidiaries as of the dates indicated and
present fairly the results of APP's and APP Subsidiaries' operations for the
periods then ended, and (c) are in accordance with the books and records of APP
and APP Subsidiaries, which have been properly maintained and are complete and
correct in all material respects.

contemplated by this Agreement, since March 31, 1997, there has not been (i)
any change in the working capital, condition (financial or otherwise), assets,
liabilities, reserves, business or operations of APP that has had or is
reasonably likely to have a Material Adverse Effect on APP; or (ii) any
declaration, setting aside or payment of any dividend or other distribution
(whether in cash, stock or property) with respect to the APP Common Stock.

Effect on APP.

which it is a party or any occurrence or state of facts whatsoever), in
violation of any applicable local, state or federal law, ordinance, regulation,
order, injunction or decree, or any other requirement of any governmental body,
agency or authority or court binding on it, or relating to its property or
business or its advertising, sales or pricing practices, except for violations
which are not reasonably likely, individually or in the aggregate, to have a
Material Adverse Effect on APP.

         APP agrees that between the date hereof and the Closing:

reasonably necessary to cause the consummation of the transactions contemplated

Agreement.

         Section 6.3      Notification of Certain Matters.  APP shall promptly
inform San Antonio in writing of (a) any notice of, or other communication

                    Covenants of APP, Seller and San Antonio

         APP, Seller and San Antonio agree as follows:

         Section 7.1      Filings; Other Action.

         (a)     San Antonio shall cooperate with APP to promptly prepare and
file with the SEC the Registration Statements on Form S-1 and Form S-4 (or
other appropriate Forms) to be filed by APP in connection with its Initial
Public Offering and offering of the shares of APP Common Stock to the Target
Interest Holders pursuant to the transactions contemplated by this Agreement
and the Other Agreements (including the prospectus constituting parts thereof,
the "Registration Statements").  APP shall obtain all necessary state
securities law or "Blue Sky" permits and approvals required to carry out the
transactions contemplated by this Agreement.  Seller and San Antonio shall
cooperate with APP in the preparation of the Registration Statements and shall
furnish all information concerning San Antonio as may be reasonably requested
in connection with any such action in a timely manner.

         (b)     Seller, San Antonio and APP and each separately represent and
warrant that (i) in the case of Seller and San Antonio, none of the written

<PAGE>   32
Seller and San Antonio specifically for inclusion in the Registration
Statements, by exhibit or otherwise and (ii) in the case of APP, will, at the
time the Registration Statements and each amendment and supplement thereto, if
any, becomes effective under the Securities Act, none of them contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading.  Seller and
San Antonio shall be entitled to review the Registration Statements and each of
the amendments thereto, if any, prior to the time each becomes effective under
the Securities Act.  Seller and San Antonio shall have no responsibility for
information contained in the Registration Statements except for information
provided by Seller or San Antonio specifically for inclusion therein.  Seller's
and San Antonio's review of the Registration Statements shall not diminish or
otherwise affect the representations, covenants and warranties of APP contained
in this Agreement.

         (c)     Seller and San Antonio shall, upon request, furnish APP with
all information concerning San Antonio, its subsidiaries, partners and
officers, and such other matters as may be reasonably requested by APP in
connection with the preparation of the Registration Statements and each of the
amendments or supplements thereto, or any other statement, filing, notice or
application made by or on behalf of each such party or any of its subsidiaries
to any governmental entity in connection with the transactions contemplated by
this Agreement.

         Section 7.2      Amendments of Schedules.  Each party hereto agrees
that, with respect to the representations and warranties of such party
contained in this Agreement, such party shall have the continuing obligation
until the Closing to supplement or amend promptly the Schedules with respect to
any matter that would have been or would be required to be set forth or
described in the Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Schedule that constitutes or reflects a
Material Adverse Effect on San Antonio may be made unless APP consents to such
amendment or supplement, and no amendment or supplement to a Schedule that
constitutes or reflects a Material Adverse Effect on APP may be made unless
Sellers and San Antonio consent to such amendment or supplement.  For purposes
of this Agreement, including without limitation for purposes of determining
whether the conditions set forth in Sections 8.1 and 9.1 have been fulfilled,
the Disclosure Schedules hereto shall be deemed to be the Disclosure Schedules
as amended or supplemented pursuant to this Section 7.2.  In the event that
Sellers or San Antonio seek to amend or supplement a Disclosure Schedule
pursuant to this Section 7.2 and APP does not consent to such amendment or
supplement, or APP seeks to amend or supplement a Disclosure Schedule pursuant
to this Section 7.2, and Seller and San Antonio do not consent, this Agreement
shall be deemed terminated by mutual consent as set forth in Section 13.1(a)
hereof.

         Section 7.3      Actions Contrary to Stated Intent.  No party hereto
will knowingly, either before or after the Closing Date, take any action that
would prevent the Exchange from qualifying as a tax-free exchange within the
meaning of Section 351 of the Code.

         Section 7.4      Public Announcements.  The parties hereto will
consult with each other before issuing any press release or making any public
statement with respect to this Agreement and the transactions contemplated
hereby and, except as may be required by applicable law, will not issue any
such press release or make any such public statement prior to such
consultation, although the foregoing shall not apply to any disclosure by APP
in any filing with the DOJ, FTC or SEC.

         Section 7.5      Expenses.  Each party to this Agreement shall be
solely responsible for their own fees and expenses with respect to the
transactions contemplated herein including, without limitation, the fees
charged by attorneys, accountants and financial advisors retained by such
parties.  The fees and





                                       27
<PAGE>   33
expenses incurred by Seller and San Antonio shall be paid by Seller in full
immediately prior to the Closing.

         Section 7.6      Registration Statements.  APP shall prepare and file
the Registration Statements with the SEC, and shall use its reasonable good
faith efforts to cause the Registration Statements to become effective under
the Securities Act and take any action required to be taken under the
applicable state "Blue Sky" or other securities laws in connection with the

                 (c)      any liability under the Securities Act, the Exchange
Act or any other federal or state "Blue Sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any (i) untrue
statement of a material fact in any Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto relating
to San Antonio (including any Partnership Subsidiary) or (ii) failure to state
information necessary to make the statements required to be stated therein not
misleading arising (in the case of either (i) or (ii)) solely from information
provided in writing to APP or its counsel by San Antonio or any Seller or their
agents specifically for inclusion in any such Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto (including, without limitation, schedules, exhibits and certifications
delivered by San Antonio or any of its agents in connection with this
Agreement).

         Notwithstanding anything herein to the contrary, nothing contained in
this Agreement shall relieve any Seller or San Antonio of any liability or
limit any liability that he, she or it may have in the case of fraud in
connection with the transactions contemplated by this Agreement.

         Section 12.2     Indemnification by APP.  Subject to the terms,
limitations and conditions of this Agreement, APP (an "Indemnifying Party")
hereby agrees to indemnify, defend and hold the Sellers, and, as applicable,
their respective directors, partners, officers, stockholders, employees,
agents, attorneys, consultants and Affiliates (each an "Indemnified Party" and
collectively, the "Indemnified Parties") harmless from and against all Damages
asserted against or incurred by such individuals and/or entities arising out of
or resulting from:

                 (a)      a breach by APP of any representation or warranty
(without giving effect to any Material Adverse Effect qualifier contained as
part of any such representation or warranty) or covenant of APP contained in
this Agreement or in any schedule or certificate delivered hereunder; and

                 (b)      any liability under the Securities Act, the Exchange
Act or any other federal or state "Blue Sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any (i) untrue
statements of a material fact in any Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto, or (ii)
failure to state information necessary to make the statements required to be
stated therein not misleading (except for any liability based upon any actual
or alleged untrue statement of material fact or an omission to state a material
fact relating to San Antonio or any Seller which was derived from any
information provided in writing by the Company or a Company Subsidiary or any
of their agents contained in the representations and warranties set forth in
this Agreement or any certificate, exhibit, schedule or instrument required to
be delivered under this Agreement.)

         Notwithstanding anything herein to the contrary, nothing contained in
this Agreement shall relieve APP of any liability or limit any liability that
it may have in the case of fraud in connection with the transactions
contemplated by this Agreement.

         Section 12.3     Conditions of Indemnification.  All claims for
indemnification under this Agreement shall be asserted and resolved as follows:





                                       33
<PAGE>   39
                 (a)      The Indemnified Party shall promptly (and, in any
event, at least ten (10) days prior to the due date for any responsive
pleadings, filings or other documents) (i) notify each Indemnifying Party of
any third-party claim or claims asserted against the Indemnified Party ("Third
Party Claim") that could give rise to a right of indemnification under this
Agreement and (ii) transmit to the Indemnifying Parties a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of Damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement.  The failure to promptly deliver a Claim Notice shall not relieve
any Indemnifying Party of its obligations to any Indemnified Party with respect
to the related Third Party Claim except to the extent that the resulting delay
is materially prejudicial to the defense of such claim.  Within thirty (30)
days after receipt of any Claim Notice (the "Election Period"), the
Indemnifying Parties shall notify the Indemnified Party (x) whether the
Indemnifying Parties dispute their potential liability to the Indemnified Party
under this Agreement with respect to such Third Party Claim and (y) whether the
Indemnifying Parties desire, at the sole cost and expense of each Indemnifying
Party, to defend the Indemnified Party against such Third Party Claim.

                 (b)      If the Indemnifying Parties notify the Indemnified
Party within the Election Period that the Indemnifying Parties elect to assume
the defense of the Third Party Claim, then the Indemnifying Parties shall have
the right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party or Indemnified Parties, such Third Party
Claim by all appropriate proceedings, which proceedings shall be prosecuted
diligently by the Indemnifying Parties to a final conclusion or settled at the
discretion of the Indemnifying Parties in accordance with this Section 12.3(b).
Except as set forth in Section 12.3(f) below, the Indemnifying Parties shall
have full control of such defense and proceedings, including any compromise or
settlement thereof.  The Indemnified Party is hereby authorized, at the sole
cost and expense of the Indemnifying Parties (but only if the Indemnified Party
is entitled to indemnification hereunder), to file, during the Election Period,
any motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Parties and not prejudicial to the Indemnifying Parties.  If requested by the
Indemnifying Parties, the Indemnified Party agrees, at the sole cost and
expense of the Indemnifying Parties, to cooperate with the Indemnifying Parties
and their counsel in contesting any Third Party Claim that the Indemnifying
Parties elect to contest, including, without limitation, the making of any
related counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person.  The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Parties pursuant to this Section 12.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Parties and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Parties, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Parties, and upon written
notification thereof, the Indemnifying Parties shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Parties shall not, in connection with any one
such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm
of attorneys at any time for the Indemnified Party, which firm shall be
designated in writing by the Indemnified Party.  Notwithstanding the foregoing,
the Indemnifying Parties shall be prohibited from confessing or settling any
criminal allegations brought against the Indemnified Party without the express
written consent of the Indemnified Party.





                                       34
<PAGE>   40
                 (c)      If the Indemnifying Parties fail to notify the
Indemnified Party within the Election Period that the Indemnifying Parties
elect to defend the Indemnified Party pursuant to Section 12.3(b), or if the
Indemnifying Parties elect to defend the Indemnified Party pursuant to Section
12.3(b) but fail diligently and promptly to prosecute or settle the Third Party
Claim, then the Indemnified Party shall have the right to defend, at the sole
cost and expense of the Indemnifying Parties (if the Indemnified Party is
entitled to indemnification hereunder), the Third Party Claim by all
appropriate proceedings, which proceedings shall be promptly and vigorously
prosecuted by the Indemnified Parties to a final conclusion or settled.  The
Indemnified Parties shall have full control of such defense and proceedings,
provided, however, that the Indemnified Parties may not enter into, without the
Indemnifying Parties' consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim.  Notwithstanding the
foregoing, if the Indemnifying Parties have delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement and if such
dispute is resolved in favor of the Indemnifying Parties, the Indemnifying
Parties shall not be required to bear the costs and expenses of the Indemnified
Parties' defense pursuant to this paragraph or of the Indemnifying Party's
participation therein at the Indemnified Party's request, and the Indemnified
Party shall reimburse the Indemnifying Parties in full for all costs and
expenses of such litigation.  The Indemnifying Parties may participate in, but
not control, any defense or settlement controlled by the Indemnified Party
pursuant to this Section 12.3(c), and the Indemnifying Parties shall bear their
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnifying Parties have been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnified Party, then the Indemnifying Parties may employ
separate counsel and upon written notification thereof, the Indemnified Party
shall not have the right to assume the defense of such action on behalf of the
Indemnifying Parties.

                 (d)      In the event any Indemnified Party should have a
claim against any Indemnifying Parties hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Parties a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification
under this Agreement.  If the Indemnifying Parties do not notify the
Indemnified Party within sixty (60) days from its receipt of the Indemnity
Notice that the Indemnifying Parties dispute such claim, the claim specified by
the Indemnified Party in the Indemnity Notice shall be deemed a liability of
the Indemnifying Parties hereunder.  If the Indemnifying Parties have timely
disputed such claim, as provided above, such dispute shall be resolved by the
procedures set forth in Section 12.7.

                 (e)      Payments of all amounts owing by any Indemnifying
Party pursuant to this Agreement relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Parties liability to the
Indemnified Party under this Agreement.  Payments of all amounts owing by the
Indemnifying Parties pursuant to Section 12.3(d) shall be made within thirty
(30) days after the later of (i) the expiration of the 60-day Indemnity Notice
period or (ii) the expiration of the period for appeal of a final adjudication
of the Indemnifying Parties liability to the Indemnified Party under this
Agreement.  During the two-year period following the Closing Date, each Seller
shall be entitled to satisfy payments owed to APP by transfer of APP Common
Stock from such Seller to APP.  For all purposes of this Agreement, the value
of each share of APP Common Stock transferred to APP pursuant to this Agreement
shall be calculated by averaging the daily closing prices for a share of APP
Common Stock for the twenty (20) consecutive trading days on which such shares
are actually traded on the Nasdaq





                                       35
<PAGE>   41
National Market preceding the date of the Claim Notice.  The number of shares
of APP Common Stock permitted to be transferred under this Section 12.3(e)
shall be diminished proportionately in accordance with the percentage of APP
Common Stock released under the Lock-Up Provisions set forth herein.  The
rights of any Seller to transfer shares of APP Common Stock in satisfaction of
payments owed to APP pursuant to this Agreement shall terminate upon the
earlier of (x) the termination of the Lock-Up Provisions set forth herein or
(y) at the end of the two-year period following the Closing Date.

                 (f)      The Indemnifying Parties shall provide the
Indemnified Party with written notice of any firm offer that is made to settle
or compromise a Third Party Claim against an Indemnified Party.  If a firm
offer is made to settle such a claim solely by the payment of money damages and
the Indemnifying Parties notify the Indemnified Party in writing that the
Indemnifying Parties agree to such settlement, but the Indemnified Party elects
not to accept and agree to it, the Indemnified Party may continue to contest or
defend such Third Party Claim and, in such event, the total maximum liability
of the Indemnifying Parties to indemnify or otherwise reimburse the Indemnified
Party hereunder with respect to such a claim shall be limited to and shall not
exceed the amount of such settlement offer, plus reasonable out-of-pocket costs
and reasonable expenses (including reasonable attorneys' fees and
disbursements) to the date of notice that the Indemnifying Parties desired to
accept such settlement.

                 (g)      Notwithstanding anything contained in this Agreement
to the contrary, Indemnifying Parties in the aggregate (i) shall have no
obligation hereunder to provide indemnification for the first $__________ of
Damages (without counting Immaterial Claims as defined below), and (ii) in no
event shall the Indemnifying Parties have any liability hereunder with respect
to any singular incident or a fact involving a breach or inaccuracy of San
Antonio if the Damages from such claim are equal to or less than $__________
("Immaterial Claims").  Notwithstanding anything to the contrary contained
herein, the obligations of each Seller hereunder shall not exceed the value of
the Exchange Consideration paid to such Seller pursuant to the Related
Acquisition, if any, on the Closing Date.

         Section 12.4     Remedies Exclusive.  The remedies provided in this
Agreement are the exclusive rights available to one party against the other,
either at law or in equity, except in the case of fraud.

         Section 12.5     Costs, Expenses and Legal Fees.  Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 12.6     Tax Benefits; Insurance Proceeds.  The total amount
of any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

         Section 12.7     Dispute Resolution.

                 (a)      Arbitration.  The parties hereto agree that any
claim, controversy, dispute or disagreement between or among any of the parties
arising out of or relating to this Agreement shall be governed exclusively by
the terms and provisions of this Section 12.7; provided, however, that within
ten (10) days from the date which any claim, controversy, dispute or
disagreement cannot be resolved and prior to commencing an arbitration
procedure pursuant to this Section 12.7, the parties shall meet to discuss and
consider other alternative dispute resolution procedures other than arbitration
including,





                                       36
<PAGE>   42
but not limited to, Judicial Arbitration & Mediation Services, Inc., if
applicable.  If at any time prior to the rendering of the decision by the
arbitrator (or pursuant to such other alternative dispute resolution procedure)
as contemplated in this Section 12.7 to the extent a party makes a written
offer to the other party proposing a settlement of the matter(s) at issue and
such offer is rejected, then the party rejecting such offer shall be obligated
to pay the costs and expenses (excluding the amount of the award granted under
the decision) of the party that offered the settlement from the date such offer
was received by such other party if the decision is for a dollar amount that is
less than the amount of such offer to settle.  Notwithstanding the foregoing,
the terms and provisions of this Section 12.7 shall not preclude any party
hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

                 (b)      Arbitrators.  In the event there is a claim,
controversy, dispute or disagreement among the parties hereto arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within thirty (30) days
of notice by a party to the other of its desire to seek arbitration under this
Section 12.7 one (1) arbitrator mutually acceptable to APP and the Sellers to
hear and decide all such claims under this Section 12.7.  Each of the
arbitrators proposed shall be impartial and independent of all parties.  If the
parties cannot agree on the selection of an arbitrator within said 30-day
period, then any party may in writing request the judge of the United States
District Court for the Western District of Texas senior in term of service to
appoint the arbitrator and, subject to this Section 12.7, such arbitrator shall
hear all arbitration matters arising under this Section 12.7.

                 (c)      Applicable Rules.

                          (1)     Each arbitration hearing shall be held at a
place in Boxar County, Texas acceptable to the arbitrator.  The arbitration
shall be conducted in accordance with the Commercial Arbitration Rules of the
American Arbitration Association to the extent such rules do not conflict with
the terms hereof; provided, however, that if the parties hereto agree to an
alternative to arbitration they may agree to an alternative set of rules,
including as to rules of evidence and procedure.  The decision of the
arbitrator shall be reduced to writing and shall be binding on the parties and
such decision shall contain a concise statement of the reasons in support of
such decision.  Judgment upon the award(s) rendered by the arbitrator may be
entered and execution had in any court of competent jurisdiction or application
may be made to such court for a judicial acceptance of the award and an order
of enforcement.  The charges and expenses of the arbitrator shall be shared
equally by the parties to the hearing.

                          (2)     The arbitration shall commence within ten
(10) days after the arbitrator is selected in accordance with the provisions of
this Section 12.7.  In fulfilling his duties with respect to determining the
amount of any loss, the arbitrator may consider such matters as, in the opinion
of the arbitrator, are necessary or helpful to make a proper valuation.  The
arbitrator may consult with and engage disinterested third parties to advise
the arbitrator.  The arbitrator shall not add any interest factor reflecting
the time value of money to the amount of any loss and shall not award any
punitive damages.

                          (3)     If the arbitrator selected hereunder should
die, resign or be unable to perform his or her duties hereunder, the parties,
or such senior judge (or such judge's successor) in the event the parties
cannot agree, shall select a replacement arbitrator.  The procedure set forth
in this Section 12.7 for selecting the arbitrator shall be followed from time
to time as necessary.

<PAGE>   43
                          (4)     As to any determination of the amount of any
loss, or as to the resolution of any other claim, controversy, dispute or
disagreement, that under the terms hereof is made subject to arbitration, no
lawsuit based on such claimed loss or such resolution shall be instituted by
the parties hereto, other than to compel arbitration proceedings or enforce the
award of the arbitrator, except as otherwise provided in Section 12.7(b).

                          (5)     All privileges under Texas and federal law,
including attorney-client and work-product privileges, shall be preserved and
protected to the same extent that such privileges would be protected in a
federal court proceeding applying Texas law.

                                  ARTICLE XIII

                                  Termination

         Section 13.1     Termination.  This Agreement may be terminated and
the Exchange may be abandoned:

                 (a)      at any time prior to the Closing Date by mutual
agreement of all parties;

                 (b)      at any time prior to the Closing Date by APP if any
material representation or warranty of any Seller or San Antonio contained in
this Agreement or in any certificate or other document executed and delivered
by any Seller or San Antonio pursuant to this Agreement is or becomes untrue or
breached in any material respect or if any Seller or San Antonio fails to
comply in any material respect with any material covenant or agreement
contained herein, and any such misrepresentation, noncompliance or breach is
not cured, waived or eliminated within thirty (30) days after receipt of
written notice thereof;

                 (c)      at any time prior to the Closing Date by Seller as to
Seller if any representation or warranty of APP contained in this Agreement or
in any certificate or other document executed and delivered by APP pursuant to
this Agreement is or becomes untrue in any material respect of if APP fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within thirty (30) days after receipt of written notice thereof;

                 (d)      at any time prior to the Closing Date by APP if, as a
result of the conduct of due diligence and regulatory compliance procedures,
APP deems termination to be advisable; or

                 (e)      by APP or Seller as to Seller if the Exchange shall
not have been consummated by September 30, 1997.

         Section 13.2     Effect of Termination.  Except as set forth in
Section 14.3, in the event this Agreement is terminated pursuant to this
Article XIV, this Agreement shall forthwith become void.

                                  ARTICLE XIV

                   Nondisclosure of Confidential Information

         Section 14.1     Non-Disclosure Covenant.  Seller and San Antonio
recognize and acknowledge that each has in the past, currently has, and in the
future may possibly have, access to certain Confidential Information of APP
that is valuable, special and a unique asset of such entity's business.  APP





                                       38
<PAGE>   44
acknowledges that it had in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of San Antonio that
is valuable, special and a unique asset of each such business.  Seller, San
Antonio and APP, severally, agree that they will not disclose such Confidential
Information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
APP, Seller and San Antonio and (b) to counsel and other advisers to APP,
Sellers and San Antonio provided that such advisers (other than counsel) agree
to the confidentiality provisions of this Section 14.1, unless (i) such
information becomes available to or known by the public generally through no
fault of San Antonio, Seller or APP, as the case may be, (ii) disclosure is
required by law or the order of any governmental authority under color of law,
provided, that prior to disclosing any information pursuant to this clause (ii)
San Antonio, Seller or APP, as the case may be, shall, if possible, give prior
written notice thereof to San Antonio, Seller or APP and provide San Antonio,
Seller or APP with the opportunity to contest such disclosure, (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, or (iv)
the disclosing party is the sole and exclusive owner of such Confidential
Information as a result of the Exchange or otherwise.  In the event of a breach
or threatened breach by Seller or San Antonio, on the one hand, and APP, on the
other hand, of the provisions of this Section, APP, Seller and San Antonio
shall be entitled to an injunction restraining the other party, as the case may
be, from disclosing, in whole or in part, such Confidential Information.
Nothing herein shall be construed as prohibiting any of such parties from
pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages.

         Section 14.2     Damages.  Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, APP, Seller and San Antonio agree
that, in the event of a breach by either of them of the foregoing covenant, the
covenant may be enforced against them by injunctions and restraining orders.

         Section 14.3     Survival.  The obligations of the parties under this
Article XIV shall survive the termination of this Agreement.

                                   ARTICLE XV

                                 Miscellaneous

         Section 15.1     Amendment; Waivers.  This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto.  Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto.  The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 15.2     Assignment.  Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any party hereto,
except by APP to a wholly owned subsidiary of APP; provided that any such
assignment shall not relieve APP of its obligations hereunder.

         Section 15.3     Parties in Interest; No Third Party Beneficiaries.
Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto.  Except as
otherwise provided herein, neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party
hereto or thereto any rights or remedies hereunder or thereunder.

         Section 15.4     Entire Agreement.  This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding
the subject matter hereof, and supersede all prior agreements and
understandings, both written and oral, among the parties, or any of them, with
respect to the subject matter hereof.

         Section 15.5     Severability.  If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 15.6     Survival of Representations, Warranties and
Covenants.  The representations, warranties and covenants contained herein
shall survive the Closing and all statements contained in any certificate,
exhibit or other instrument delivered by or on behalf of San Antonio, Seller or
APP pursuant to this Agreement shall be deemed to have been representations and
warranties made by San Antonio, Seller and APP, respectively.  Notwithstanding
any provision in this Agreement to the contrary, the representations and
warranties contained herein shall survive the Closing until the second
anniversary of the Closing Date except that (a) the representations and
warranties set forth in Section 3.20 with respect to environmental matters
shall survive for a period of ten (10) years, (b) the representations and
warranties set forth in Section 3.29 with respect to tax matters shall survive
until such time as the limitations period has run for all tax periods ended

                          CONVERTIBLE PROMISSORY NOTE

         Subject to the terms and conditions of this Note, for good and valuable
consideration received, American Physician Partners, Inc., a Delaware
corporation (the "Company"), promises to pay to the order of
_____________________________________________________________, whose address is
________________________________________________________________________________
_______________________________ (the "Holder"), the principal amount of
___________________ Dollars ($______________), plus simple interest accrued on
unpaid principal from the date of this Note until paid at the rate of six
percent (6.0%) per annum. All accrued but unpaid interest to date shall be due
and payable upon the closing of an initial public offering of the Company's
Common Stock. All remaining amounts of accrued but unpaid interest shall be due
and payable upon the earlier to occur of (i) payment of the principal amount of
this Note as provided in Section 1 hereof, (ii) redemption of the Note as
provided in Section 1(b) hereof, or (iii) conversion of the principal of this
Note as provided in Section 2 hereof. In the event the Notes are not converted
by January 31, 1998, all accrued but unpaid interest to date shall be due and
payable and the rate of interest hereunder will increase to prime rate as
published in The Wall Street Journal plus two percent (2%) per annum, and all
accrued but unpaid interest thereafter shall be due and payable on a quarterly
basis. This Note may be one of a series of Convertible Promissory Notes
(collectively, the "Notes") identical in substance to this Note except as to the
Holder and principal amount.

         The following is a statement of the rights of the Holder and the terms
and conditions to which this Note is subject, to which the Holder, by
acceptance of this Note by its signature below, and the Company, by issuance of
this Note, agrees:

         1.      PAYMENT

                 (a)      Obligation.  The outstanding principal under this
Note and the accrued interest thereon will be due and payable upon redemption
(as provided in Section 2(c) hereof) upon demand by the Holder at any time on
or after January 31, 1998, if this Note is not converted into Conversion Shares
(as defined in Section 2(a) hereof) prior thereto pursuant to Section 2 hereof.
All payments of principal and/or interest under this Note will be made at the
address of the Holder set forth above or at such other address as is provided
by the Holder to the Company in writing.



<PAGE>   2



                 (b)      Optional Redemption.  The Company may redeem the
Notes in whole or in part, upon or after the initial public offering, on at
least fifteen (15) days' notice together with accrued and unpaid interest.  All
amounts paid upon redemption will be applied to accrued but unpaid interest
first and then to unpaid principal.  Any payments upon redemption made by the
Company on any of the Notes will be made simultaneously on all Notes in
identical amount (if all Notes are of the same principal amount) or an amount
prorated among the Notes in proportion to the principal amounts of each Note
(if the Notes are in different principal amounts).  Upon distribution of
written notice of redemption by the Company, the Holders may convert the
principal of such Notes into Common Stock upon approval of at least fifty
percent (50%) of the outstanding principal amount of Notes.

         2.      CONVERSION

                 (a)      Conversion.  If prior to the date upon which payment
of this Note is lawfully demanded by the Holder, the Company completes a public
sale of its capital stock, in which at least an aggregate of $10,000,000 is
raised (a "Securities Sale"), all outstanding principal under this Note (and
all other Notes) will convert upon approval of the Holders of at least fifty
percent (50%) of the outstanding principal amount of the Notes (such date of
conversion is herein referred to as the "Conversion Date") into Common Stock
("Conversion Shares"); at the initial conversion rate of $8.00 per share;
provided that such conversion rate is subject to adjustment as described by the
terms of the Private Placement Memorandum dated September 12, 1996.

                 (b)      Mechanics and Effect of Conversion.  The conversion
of this Note into the Conversion Shares will be deemed to have been made
immediately upon the affirmative vote of the required principal amount of the
Notes and the Holder will be treated for all purposes as the record holder of
such Conversion Shares on the Conversion Date.  Upon conversion of this Note,
the Company will be forever released from all of its obligations and
liabilities under this Note.  No fractional shares will be issued upon
conversion of this Note.  In lieu of any fractional share to which the Holder
would otherwise be entitled, the Company will pay the cash value of that
fractional share to the Holder, as provided herein.  The Company will give
prompt written notice to the Holder and to all holders of the other Notes, of
the proposed Conversion Date.  The Holder will surrender this Note on or before
10 days following the Conversion Date at the principal offices of the Company
or its transfer agent.  The Company will, as soon as practicable thereafter,
issue and deliver to such Holder a certificate or certificates for the number
of Conversion Shares to which such Holder is entitled (bearing such legends as
may be required by applicable state and federal securities laws in the opinion
of legal counsel of the Company), including a check payable to the Holder for
any cash amounts payable for any fractional share resulting from the conversion
of this Note and a check for all interest due the Holder under the terms of the
Note.

         3.      TRANSFERABILITY.  This Note is not transferable.

         4.      GOVERNING LAW.  This Note will be governed by and construed in
accordance with the laws of the State of Texas, excluding that body of law
relating to conflict of laws.

         5.      WAIVER.  The Company hereby waives diligence, presentment,
                 demand, protest and notice of dishonor.

         6.      COLLECTION EXPENSES.  The Company promises and agrees to pay
all costs of collection of this Note including, but not limited to, reasonable
attorneys' fees, paid or incurred by the Holder on account of such collection,
whether or not suit is filed with respect thereto and whether or not such costs
are paid or incurred, or to be paid or incurred, prior to or after entry of
judgment.

         IN WITNESS WHEREOF, the Company has caused this Note to be issued as of
the date first written above.

Two and the Automatic Option Grant Program specified in Article Three. Under the

         IV.      ADMINISTRATION OF THE PLAN

with respect to all other persons eligible to participate in those programs may,
at the Board's discretion, be vested in the Primary Committee or a Secondary
Committee, or the Board may retain the power to administer those programs with
respect to all such persons. The members of the Secondary Committee may be Board
members who are Employees eligible to receive discretionary option grants or
direct stock issuances under the Plan or any other stock option, stock
appreciation, stock bonus or other stock plan of the Corporation (or any Parent
or Subsidiary).

                  C. Members of the Primary Committee or any Secondary Committee
shall serve for such period of time as the Board may determine and may be
removed by the Board at any time. The Board may also at any time terminate the
functions of any Secondary Committee and reassume all powers and authority
previously delegated to such committee.

                  D. Each Plan Administrator shall, within the scope of its
administrative functions under the Plan, have full power and authority (subject
to the provisions of the Plan) to establish such rules and regulations as it may
deem appropriate for proper administration of the Discretionary Option Grant
Program and to make such determinations under, and issue such interpretations
of, the provisions of such program and any outstanding options thereunder as it
may deem necessary or advisable. Decisions of the Plan Administrator within the
scope of its



                                       6.

administrative functions under the Plan shall be final and binding on all
parties who have an interest in the Discretionary Option Grant Program under its
jurisdiction or any option thereunder.

                  E. Service on the Primary Committee or the Secondary Committee
shall constitute service as a Board member, and members of each such committee
shall accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee. No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants under the Plan.

                  F. Administration of the Automatic Option Grant Program shall
be self- executing in accordance with the terms of that program, and no Plan
Administrator shall exercise any discretionary functions with respect to any
option grants made under that program.

         V.       ELIGIBILITY

                  A. The persons eligible to participate in the Discretionary
Option Grant Program under Article Two shall be limited to the following:

                     (i) Employees;

                    (ii) non-employee members of the Board or the non-employee
         members of the board of directors of any Parent or Subsidiary; and

                   (iii) consultants or other independent contractors who 
         provide valuable services to the Corporation (or any Parent or 
         Subsidiary).

                  B. The individuals who shall be eligible to participate in the
Automatic Option Grant Program shall be limited to (i) those individuals serving
as non-employee Board members on the Common Stock Registration Date who have not
previously received a stock option grant from the Corporation, (ii) those
individuals who first become non-employee Board members after the Common Stock
Registration Date, whether through appointment by the Board or election by the
Corporation's stockholders, and (iii) those individuals who continue to serve as
non-employee Board members after one or more Annual Stockholders Meetings held
after the Common Stock Registration Date. A non-employee Board member who has
previously been in the employ of the Corporation (or any Parent or Subsidiary)
shall not be eligible to receive an option grant under the Automatic Option
Grant Program on the date of the Common Stock Registration Date or at the time
he or she first becomes a non-employee Board member, but shall be eligible to
receive periodic option grants under the Automatic Option Grant Program while he
or she continues to serve as a non-employee Board member.

                  C. The Plan Administrator shall have full authority to
determine, with respect to the option grants made under the Discretionary Option
Grant Program, which eligible



                                       7.

<PAGE>   8

individuals are to receive option grants, the number of shares to be covered by
each such grant, the status of the granted option as either an Incentive Option
or a Non-Statutory Option, the time or times at which each granted option is to
become exercisable, the maximum term for which the option may remain outstanding
and the vesting schedule to be applicable to the option shares.

         VI.      STOCK SUBJECT TO THE PLAN

                  A. Shares of Common Stock shall be available for issuance
under the Plan and shall be drawn from either the Corporation's authorized but
unissued shares of Common Stock or from reacquired shares of Common Stock. The
maximum number of shares of Common Stock which may be issued over the term of
the Plan shall not exceed 3,000,000 shares, subject to adjustment from time to
time in accordance with the provisions of this Section VI.

                  B. From and after the Common Stock Registration Date, no
individual participating in the Plan shall be granted options and separately
exercisable stock appreciation rights for more than 1,000,000 shares of Common
Stock in the aggregate over the remaining term of the Plan. For purposes of such
limitation, no options and stock appreciation rights made prior to such Common
Stock Registration Date shall be taken into account.

                  C. Should one or more outstanding options under this Plan
expire or terminate for any reason prior to exercise in full (including any
option cancelled in accordance with the cancellation-regrant provisions of
Section IV of Article Two of the Plan), then the shares subject to the portion
of each option not so exercised shall be available for subsequent issuance under
the Plan. Shares subject to any option or portion thereof surrendered in
accordance with Section V of Article Two shall be added back to the number of
shares of Common Stock available for subsequent option grants under the Plan. In
addition, should the exercise price of an outstanding option under the Plan be
paid with shares of Common Stock, then the number of shares of Common Stock
available for issuance under the Plan shall be reduced by the gross number of
shares for which the option is exercised and not by the net number of shares of
Common Stock actually issued to the holder of such option.

                  D. Should any change be made to the Common Stock issuable
under the Plan by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, then appropriate adjustments shall be made to (i) the maximum
number and/or class of securities issuable under the Plan, (ii) the maximum
number and/or class of securities for which any one individual participating in
the Plan may be granted options and separately exercisable stock appreciation
rights in the aggregate after the Common Stock Registration Date, (iii) the
number and/or class of securities for which grants are subsequently to be made
under the Automatic Option Grant Program and (iv) the number and/or class of
securities and price per share in effect under each option outstanding under the
Plan. Such adjustments to the outstanding options are to be effected in a manner
which shall preclude the enlargement or dilution of rights and benefits under
such options. The adjustments determined by the Plan Administrator shall be
final, binding and conclusive.

                       DISCRETIONARY OPTION GRANT PROGRAM

         I.       TERMS AND CONDITIONS OF OPTIONS

                  Options granted pursuant to the Discretionary Option Grant
Program shall be authorized by action of the Plan Administrator and may, at the
Plan Administrator's discretion, be either Incentive Options or Non-Statutory
Options. Individuals who are not Employees of the Corporation or any Parent or
Subsidiary may only be granted Non-Statutory Options. Each granted option shall
be evidenced by one or more instruments in the form approved by the Plan
Administrator; provided, however, that each such instrument shall comply with
the terms and conditions specified below. Each instrument evidencing an
Incentive Option shall, in addition, be subject to the applicable provisions of
Section II of this Article Two.

                  A. Exercise Price.

                     1. The exercise price per share shall be fixed by the Plan
Administrator in accordance with the following provisions:

                           a. The exercise price per share of the Common Stock
         subject to an Incentive Option shall in no event be less than one
         hundred percent (100%) of the Fair Market Value of such Common Stock on
         the grant date.

                           b. The exercise price per share of the Common Stock
         subject to a Non-Statutory Option shall in no event be less than
         eighty-five percent (85%) of the Fair Market Value of such Common Stock
         on the grant date.

                     2. The exercise price shall become immediately due upon
exercise of the option and, subject to the provisions of Section I of Article
Four and the instrument evidencing the grant, shall be payable in cash or check
made payable to the Corporation. Should the option be exercised after the Common
Stock Registration Date, then the exercise price may also be paid in one of the
alternative forms specified below:

                           a. in shares of Common Stock held for the requisite
         period necessary to avoid a charge to the Corporation's earnings for
         financial reporting purposes and valued at Fair Market Value on the
         Exercise Date; or

                           b. to the extent the option is exercised through a
         broker-dealer sale and remittance procedure pursuant to which the
         Optionee shall provide concurrent irrevocable written instructions (i)
         to a Corporation-designated brokerage firm to effect the immediate sale
         of the purchased shares and remit to the Corporation, out of the sale
         proceeds available on the settlement date, sufficient funds to cover
         the aggregate exercise price payable for the purchased



                                       9.

<PAGE>   10

         shares plus all applicable Federal, state and local income and
         employment taxes required to be withheld by the Corporation in
         connection with such purchase and (ii) to the Corporation to deliver
         the certificates for the purchased shares directly to such brokerage
         firm in order to complete the sale transaction.

                     Except to the extent the sale and remittance procedure is
utilized in connection with the exercise of the option for shares, payment of
the exercise price for the purchased shares must accompany such notice.

                     B. Term and Exercise of Options. Each option granted under
this Discretionary Option Grant Program shall be exercisable at such time or
times and during such period as is determined by the Plan Administrator and set
forth in the instrument evidencing the grant. No such option, however, shall
have a maximum term in excess of ten (10) years measured from the grant date.

                     C. Termination of Service.

                        1. The following provisions shall govern the exercise
period applicable to any outstanding options held by the Optionee at the time of
cessation of Service.

                           a. Should an Optionee cease Service for any reason
         (including death or Permanent Disability) while holding one or more
         outstanding options under this Article Two, then none of those options
         shall (except to the extent otherwise provided pursuant to subparagraph
         3 below) remain exercisable for more than a thirty-six (36)-month
         period (or such shorter period determined by the Plan Administrator and
         set forth in the instrument evidencing the grant) measured from the
         date of such cessation of Service.

                           b. Any option held by the Optionee under this Article
         Two and exercisable in whole or in part on the date of his or her death
         may be subsequently exercised by the personal representative of the
         Optionee's estate or by the person or persons to whom the option is
         transferred pursuant to the Optionee's will or in accordance with the
         laws of descent and distribution. However, the right to exercise such
         option shall lapse upon the (i) the third anniversary of the date of
         the Optionee's death (or such shorter period determined by the Plan
         Administrator and set forth in the instrument evidencing the grant) or
         (ii) the specified expiration date of the option term. Accordingly,
         upon the occurrence of the earlier event, the option shall terminate
         and cease to remain outstanding.

                           c. Under no circumstances shall any such option be
         exercisable after the specified expiration date of the option term.



                                       10.

<PAGE>   11

                           d. During the applicable post-Service exercise
         period, the option may not be exercised in the aggregate for more than
         the number of shares (if any) in which the Optionee is vested at the
         time of his or her cessation of Service. Upon the expiration of the
         limited post-Service exercise period or (if earlier) upon the specified
         expiration date of the option term, each such option shall terminate
         and cease to remain outstanding with respect to any shares for which
         the option has not otherwise been exercised. However, each outstanding
         option shall immediately terminate and cease to remain outstanding, at
         the time of the Optionee's cessation of Service, with respect to any
         shares for which the option is not otherwise at that time exercisable.

                           e. Should (i) the Optionee's Service be terminated
         for Misconduct or (ii) the Optionee violate any covenant or agreement
         not to compete with the Corporation, any Parent, Subsidiary or
         professional medical entity affiliated with the Corporation, any Parent
         or Subsidiary, then in any such event all outstanding options held by
         the Optionee under this Article Two shall terminate immediately and
         cease to remain outstanding.

                        2. The Plan Administrator shall have complete
discretion, exercisable either at the time the option is granted or at any time
while the option remains outstanding, to permit one or more options held by the
Optionee under this Article Two to be exercised, during the limited post-Service
exercise period applicable under this paragraph C, not only with respect to the
number of shares of Common Stock for which each such option is exercisable at
the time of the Optionee's cessation of Service but also with respect to one or
more subsequent installments of shares for which the option would otherwise have
become exercisable had such cessation of Service not occurred.

                        3. The Plan Administrator shall also have full power and
authority, exercisable either at the time the option is granted or at any time
while the option remains outstanding, to extend the period of time for which the
option is to remain exercisable following the Optionee's cessation of Service or
death from the limited period in effect under subparagraph 1 above to such
greater period of time as the Plan Administrator shall deem appropriate. In no
event, however, shall such option be exercisable after the specified expiration
date of the option term.

                     D. Stockholder Rights. An Optionee shall have no
stockholder rights with respect to any shares covered by the option until such
individual shall have exercised the option and paid the exercise price for the
purchased shares.

                     E. First Refusal Rights. Until the Common Stock
Registration Date, the Corporation shall have the right of first refusal with
respect to any proposed sale or other disposition by the Optionee (or any
successor in interest by reason of purchase, gift or other transfer) of any
shares of Common Stock issued under the Plan. Such right of first refusal shall



                                       11.

<PAGE>   12

be exercisable in accordance with the terms and conditions established by the
Plan Administrator and set forth in the agreement evidencing such right.

                     F. Limited Transferability of Options. During the lifetime
of the Optionee, Incentive Options shall be exercisable only by the Optionee and
shall not be assignable or transferable other than by will or by the laws of
descent and distribution following the Optionee's death. However, a
Non-Statutory Option may, in connection with the Optionee's estate plan, be
assigned in whole or in part during the Optionee's lifetime to one or more
members of the Optionee's immediate family or to a trust established exclusively
for one or more such family members. The assigned portion may only be exercised
by the person or persons who acquire a proprietary interest in the option
pursuant to the assignment. The terms applicable to the assigned portion shall
be the same as those in effect for the option immediately prior to such
assignment and shall be set forth in such documents issued to the assignee as
the Plan Administrator may deem appropriate.

         II.         INCENTIVE OPTIONS

                     The terms and conditions specified below shall be
applicable to all Incentive Options granted under this Article Two. Incentive
Options may only be granted to individuals who are Employees. Options which are
specifically designated as Non-Statutory Options when issued under the Plan
shall not be subject to such terms and conditions.

                     A. Dollar Limitation. The aggregate Fair Market Value
(determined as of the respective date or dates of grant of options to purchase
Common Stock) of the Common Stock for which one or more options granted to any
Employee under this Plan (or any other option plan of the Corporation or any
Parent or Subsidiary) may for the first time become exercisable as incentive
stock options under the Federal tax laws during any one calendar year shall not
exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the
Employee holds two (2) or more such options which become exercisable for the
first time in the same calendar year, the foregoing limitation on the
exercisability of such options as incentive stock options under the Federal tax
laws shall be applied on the basis of the order in which such options are
granted. Should the number of shares of Common Stock for which any Incentive
Option first becomes exercisable in any calendar year exceed the applicable One
Hundred Thousand Dollar ($100,000) limitation, then that option may nevertheless
be exercised in such calendar year for the excess number of shares as a
Non-Statutory Option under the Federal tax laws.

                     B. 10% Stockholder. If any individual to whom an Incentive
Option is granted is the owner of stock (as determined under Section 424(d) of
the Code) possessing more than ten percent (10%) of the total combined voting
power of all classes of stock of the Corporation or any Parent or Subsidiary,
then the exercise price per share shall not be less than one hundred ten percent
(110%) of the Fair Market Value per share of Common Stock on the grant date, and
the option term shall not exceed five (5) years, measured from the grant date.



                                       12.

<PAGE>   13

                     Except as modified by the preceding provisions of this
Section II, the provisions of Articles One, Two and Four of the Plan shall apply
to all Incentive Options granted hereunder.

         III.        CORPORATE TRANSACTION/CHANGE IN CONTROL

                     A. In the event of any Corporate Transaction, each option
which is at the time outstanding under this Article Two shall automatically
accelerate so that each such option shall, immediately prior to the specified
effective date for the Corporate Transaction, become fully exercisable with
respect to the total number of shares of Common Stock at the time subject to
such option and may be exercised for all or any portion of such shares. However,
an outstanding option under this Article Two shall NOT so accelerate if and to
the extent: (i) such option is, in connection with the Corporate Transaction,
either to be assumed by the successor corporation or parent thereof or to be
replaced with a comparable option to purchase shares of the capital stock of the
successor corporation or parent thereof, (ii) such option is to be replaced with
a cash incentive program of the successor corporation which preserves the option
spread existing at the time of the Corporate Transaction and provides for
subsequent payout in accordance with the same vesting schedule applicable to
such option or (iii) the acceleration of such option is subject to other
limitations imposed by the Plan Administrator at the time of the option grant.
The determination of option comparability under clause (i) above shall be made
by the Plan Administrator, and its determination shall be final, binding and
conclusive.

                     B. Immediately following the consummation of the Corporate
Transaction, all outstanding options under this Article Two shall terminate and
cease to remain outstanding, except to the extent assumed by the successor
corporation or its parent company.

                     C. Each outstanding option under this Article Two which is
assumed in connection with the Corporate Transaction or is otherwise to continue
in effect shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply and pertain to the number and class of securities which
would have been issued to the option holder, in consummation of such Corporate
Transaction, had such person exercised the option immediately prior to such
Corporate Transaction. Appropriate adjustments shall also be made to the
exercise price payable per share, provided the aggregate exercise price payable
for such securities shall remain the same. In addition, the class and number of
securities available for issuance under the Plan on both an aggregate and per
individual basis following the consummation of the Corporate Transaction shall
be appropriately adjusted.

                     D. The Plan Administrator shall have the discretion,
exercisable either at the time the option is granted or at any time while the
option remains outstanding, to provide (upon such terms as it may deem
appropriate) for the automatic acceleration of one or more outstanding options
under this Article Two which are assumed or replaced in the Corporate
Transaction and do not otherwise accelerate at that time, in the event the
Optionee's Service should subsequently terminate by reason of an Involuntary
Termination within a designated period (not to exceed eighteen (18) months)
following such Corporate Transaction. Each option



                                       13.

<PAGE>   14

so accelerated shall remain exercisable for shares until the earlier of (i) the
expiration of the option term of (ii) the expiration of the one (1)-year period
measured from the effective date of the Involuntary Termination.

                     E. The Plan Administrator shall have the discretionary
authority, exercisable either in advance of any actually anticipated Change in
Control or at the time of an actual Change in Control, to provide for the
automatic acceleration of one or more outstanding options under this Article Two
upon the occurrence of the Change in Control. The Plan Administrator shall also
have full power and authority to condition any such option acceleration upon the
subsequent termination of the Optionee's Service within a specified period
following the Change in Control.

                     F. Any options accelerated in connection with the Change in
Control shall remain fully exercisable until the expiration or sooner
termination of the option term.

                     G. The grant of options under this Article Two shall in no
way affect the right of the Corporation to adjust, reclassify, reorganize or
otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

                     H. The portion of any Incentive Option accelerated under
this Section III in connection with a Corporate Transaction or Change in Control
shall remain exercisable as an incentive stock option under the Federal tax laws
only to the extent the dollar limitation of Section II of this Article Two is
not exceeded. To the extent such dollar limitation is exceeded, the accelerated
portion of such option shall be exercisable as a non-statutory option under the
Federal tax laws.

         IV.         CANCELLATION AND REGRANT OF OPTIONS

                     The Plan Administrator shall have the authority to effect,
at any time and from time to time, with the consent of the affected Optionees,
the cancellation of any or all outstanding options under the Plan and to grant
in substitution new options under the Plan covering the same or different
numbers of shares of Common Stock but with an exercise price per share not less
than (i) eighty-five percent (85%) of the Fair Market Value per share of Common
Stock on the new grant date in the case of a Non-Statutory Option or (ii) one
hundred percent (100%) of such Fair Market Value in the case of an Incentive
Option.

         V.          STOCK APPRECIATION RIGHTS

                     A. Provided and only if the Plan Administrator determines
in its discretion to implement the stock appreciation rights provisions of this
Section V, one or more Optionees may be granted the right, exercisable upon such
terms and conditions as the Plan Administrator may establish, to surrender all
or part of an unexercised option under this Article Two in exchange for a
distribution from the Corporation in an amount equal to the excess of (i) the
Fair



                                       14.

<PAGE>   15

Market Value (on the option surrender date) of the number of shares in which the
Optionee is at the time vested under the surrendered option (or surrendered
portion thereof) over (ii) the aggregate exercise price payable for such shares.

                     B. No surrender of an option shall be effective hereunder
unless it is approved by the Plan Administrator. If the surrender is so
approved, then the distribution to which the Optionee shall accordingly become
entitled under this Section V may be made in shares of Common Stock valued at
Fair Market Value on the option surrender date, in cash, or partly in shares and
partly in cash, as the Plan Administrator shall in its sole discretion deem
appropriate.

                     C. If the surrender of an option is rejected by the Plan
Administrator, then the Optionee shall retain whatever rights the Optionee had
under the surrendered option (or surrendered portion thereof) on the option
surrender date and may exercise such rights at any time prior to the later of
(i) five (5) business days after the receipt of the rejection notice or (ii) the
last day on which the option is otherwise exercisable in accordance with the
terms of the instrument evidencing such option, but in no event may such rights
be exercised more than ten (10) years after the date of the option grant.

                     D. One or more officers of the Corporation may, in the Plan
Administrator's sole discretion, be granted limited stock appreciation rights in
tandem with their outstanding options under this Article Two. Upon the
occurrence of a Hostile Take-Over after the Common Stock Registration Date, the
officer shall have a thirty (30)-day period in which he or she may surrender any
outstanding options with such a limited stock appreciation right, to the extent
such option is at the time exercisable for fully vested shares of Common Stock.
The officer shall in return be entitled to a cash distribution from the
Corporation in an amount equal to the excess of (i) the Take-Over Price of the
vested shares of Common Stock at the time subject to each surrendered option (or
surrendered portion of such option) over (ii) the aggregate exercise price
payable for such shares. The cash distribution shall be made within five (5)
days following the date the option is surrendered to the Corporation, and
neither the approval of the Plan Administrator nor the consent of the Board
shall be required in connection with the option surrender and cash distribution.
Any unsurrendered portion of the option shall continue to remain outstanding and
become exercisable in accordance with the terms of the instrument evidencing
such grant.

                     E. The shares of Common Stock subject to any option
surrendered for an appreciation distribution pursuant to this Section V shall
NOT be available for subsequent issuance under the Plan.

                         AUTOMATIC OPTION GRANT PROGRAM

         I.          OPTION TERMS

                     A. Grant Dates. Option grants shall be made on the dates
specified below:

                        1. Each individual serving as a non-employee Board
member shall automatically be granted on the date such individual is first
elected or appointed as a non-employee Board member a Non-Statutory Option to
purchase 30,000 shares of Common Stock, provided that such individual has not
previously been in the employ of the Corporation or any Parent or Subsidiary and
has not previously received a stock option grant from the Corporation.

                        2. On the date of each Annual Stockholders Meeting held
after the Common Stock Registration Date, each individual who is to continue to
serve as an Eligible Director, whether or not that individual is standing for
re-election to the Board at that particular Annual Stockholders Meeting, shall
automatically be granted a Non-Statutory Option to purchase 10,000 shares of
Common Stock, provided the initial 30,000-share option grant to such individual
was made at least 3 years prior to the date of such meeting. There shall be no
limit on the number of such 10,000-share option grants any one Eligible Director
may receive over his or her period of Board service, and non-employee Board
members who have previously been in the employ of the Corporation (or any Parent
or Subsidiary) shall be eligible to receive one or more such annual option
grants over their period of continued Board service.

                     B. Exercise Price.

                        1. The exercise price per share shall be equal to one
hundred percent (100%) of the Fair Market Value per share of Common Stock on the
option grant date.

                        2. The exercise price shall be payable in one or more of
the alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

                     C. Option Term. Each option shall have a term of ten (10)
years measured from the option grant date.

                     D. Exercise of Options. The automatic option grants
referred to in I.A.1 of this Article Three shall become exercisable (i) with
respect to 10,000 shares, on the first anniversary of the automatic grant date
and (ii) with respect to the remaining shares, in twenty-four (24) equal monthly
installments over the next twenty-four (24) months of Board service measured
from the first anniversary of the automatic grant date. Each annual 10,000-share



                                       16.

<PAGE>   17

option grant shall become exercisable in twelve (12) equal monthly installments
over the twelve (12) months of Board service measured from the automatic grant
date.

                     E. Termination of Board Service. The following provisions
shall govern the exercise of any options held by the Optionee at the time the
Optionee ceases to serve as a Board member:

                           (i) The Optionee shall have a twelve (12)-month
                  period following the date of such cessation of Board service
                  in which to exercise each such option.

                           (ii) During the twelve (12)-month exercise period,
                  the option may not be exercised in the aggregate for more than
                  the number of shares of Common Stock for which the option is
                  exercisable at the time of the Optionee's cessation of Board
                  service.

                           (iii) In no event shall the option remain exercisable
                  after the expiration of the option term. Upon the expiration
                  of the twelve (12)-month exercise period or (if earlier) upon
                  the expiration of the option term, the option shall terminate
                  and cease to be outstanding for any shares for which the
                  option has not been exercised. However, the option shall,
                  immediately upon the Optionee's cessation of Board service for
                  any reason other than death or Permanent Disability, terminate
                  and cease to be outstanding to the extent the option is not
                  otherwise at that time exercisable for shares.

         II.         CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

                     A. In the event of any Corporate Transaction, the shares of
Common Stock at the time subject to each outstanding option but not otherwise
exercisable shall become exercisable in full so that each such option shall,
immediately prior to the effective date of the Corporate Transaction, become
fully exercisable for all of the shares of Common Stock at the time subject to
such option and may be exercised for all or any portion of those shares of
Common Stock. Immediately following the consummation of the Corporate
Transaction, each automatic option grant shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

                     B. In connection with any Change in Control, the shares of
Common Stock at the time subject to each outstanding option but not otherwise
exercisable shall become exercisable in full so that each such option shall,
immediately prior to the effective date of the Change in Control, become fully
exercisable for all of the shares of Common Stock at the time subject to such
option and may be exercised for all or any portion of those shares of Common
Stock. Each such option shall remain exercisable for such option shares until
the expiration or



                                       17.

<PAGE>   18

sooner termination of the option term or the surrender of the option in
connection with a Hostile Take-Over.

                     C. Upon the occurrence of a Hostile Take-Over, the Optionee
shall have a thirty (30)-day period in which to surrender to the Corporation
each of his or her outstanding automatic option grants. The Optionee shall in
return be entitled to a cash distribution from the Corporation in an amount
equal to the excess of (i) the Take-Over Price of the shares of Common Stock at
the time subject to each surrendered option over (ii) the aggregate exercise
price payable for such shares. Such cash distribution shall be paid within five
(5) days following the surrender of the option to the Corporation. No approval
or consent of the Board or any Plan Administrator shall be required in
connection with such option surrender and cash distribution.

                     D. Each option which is assumed in connection with a
Corporate Transaction shall be appropriately adjusted, immediately after such
Corporate Transaction, to apply to the number and class of securities which
would have been issuable to the Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction. Appropriate adjustments shall also be made to the exercise price
payable per share under each outstanding option, provided the aggregate exercise
price payable for such securities shall remain the same.

                     E. The grant of options under the Automatic Option Grant
Program shall in no way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

         III.        REMAINING TERMS

                     The remaining terms of each option granted under the
Automatic Option Grant Program shall be the same as the terms in effect for
option grants made under the Discretionary Option Grant Program.

                                  ARTICLE FOUR
                                  MISCELLANEOUS

         I.          LOANS OR INSTALLMENT PAYMENTS

                     A. The Plan Administrator may, in its discretion, assist
any Optionee, to the extent such Optionee is an Employee (including an Optionee
who is an officer of the Corporation), in the exercise of one or more options
granted to such Optionee under the Discretionary Option Grant Program, including
the satisfaction of any Federal, state and local income and employment tax
obligations arising therefrom, by (i) authorizing the extension of a loan from
the Corporation to such Optionee or (ii) permitting the Optionee to pay the
exercise price for the purchased shares in installments over a period of years.
The terms of any loan or installment method of payment (including the interest
rate and terms of repayment) shall be upon



                                       18.

<PAGE>   19

such terms as the Plan Administrator specifies in the applicable option
agreement or otherwise deems appropriate under the circumstances. Loans or
installment payments may be authorized with or without security or collateral.
However, the maximum credit available to the Optionee may not exceed the
exercise price of the acquired shares plus any Federal, state and local income
and employment tax liability incurred by the Optionee in connection with the
acquisition of such shares.

                     B. The Plan Administrator may, in its absolute discretion,
determine that one or more loans extended under this financial assistance
program shall be subject to forgiveness by the Corporation in whole or in part
upon such terms and conditions as the Plan Administrator may deem appropriate.

         II.         TAX WITHHOLDING

                     The Corporation's obligation to deliver shares of Common
Stock upon the exercise of stock options for such shares under the Plan shall be
subject to the satisfaction of all applicable Federal, State and local income
and employment tax withholding requirements.

                     The Plan Administrator may, in its discretion, provide any
or all holders of non- statutory options under the Plan with the right to use
shares of the Corporation's Common Stock in satisfaction of all or part of the
Federal, state and local income and employment tax liabilities incurred by such
holders in connection with the exercise of their options (the "Taxes"). Such
right may be provided to any such holder in either or both of the following
formats:

                     a. Stock Withholding: The holder of the non-statutory
         option may be provided with the election to have the Corporation
         withhold, from the shares of Common Stock otherwise issuable upon the
         exercise of such non-statutory option, a portion of those shares with
         an aggregate Fair Market Value equal to the percentage of the
         applicable Taxes (not to exceed one hundred percent (100%)) designated
         by the holder.

                     b. Stock Delivery: The Plan Administrator may, in its
         discretion, provide the holder of the non-statutory option with the
         election to deliver to the Corporation, at the time the non-statutory
         option is exercised, one or more shares of Common Stock previously
         acquired by such individual (other than in connection with the option
         exercise triggering the Taxes) with an aggregate Fair Market Value
         equal to the percentage of the Taxes incurred in connection with such
         option exercise (not to exceed one hundred percent (100%)) designated
         by the holder.

         III.        AMENDMENT OF THE PLAN AND AWARDS

                     A. The Board has complete and exclusive power and authority
to amend or modify the Plan (or any component thereof) in any or all respects
whatsoever. However, no such amendment or modification shall adversely affect
rights and obligations with respect to options at the time outstanding under the
Plan, unless the Optionee consents to such amendment. In addition, certain
amendments may require stockholder approval pursuant to applicable laws or
regulations.

                     B. (i) Options to purchase shares of Common Stock may be
granted under the Discretionary Option Grant Program which are in excess of the
number of shares then available for issuance under the Plan, provided any excess
shares actually issued under the Discretionary Option Grant Program are held in
escrow until stockholder approval is obtained for a sufficient increase in the
number of shares available for issuance under the Plan. If such stockholder
approval is not obtained within twelve (12) months after the date the first such
excess option grants or excess share issuances are made, then (i) any
unexercised excess options shall terminate and cease to be exercisable and (ii)
the Corporation shall promptly refund the purchase price paid for any excess
shares actually issued under the Plan and held in escrow, together with interest
(at the applicable Short Term Federal Rate) for the period the shares were held
in escrow.

         IV.         EFFECTIVE DATE AND TERM OF PLAN

                     A. This Plan shall become effective immediately upon
adoption by the Board and stock options may be made under Articles Two and Three
of the Plan from and after such Effective Date. However, no options granted
under the Plan shall become exercisable unless and until the Plan is approved by
the Corporation's stockholders within twelve (12) months after the Effective
Date. Should such stockholder approval not be obtained, then all stock options
made under this Plan shall terminate and cease to remain outstanding, and no
further option grants shall be made under the Plan.

                     B. The Plan shall terminate upon the earliest of (i) April
30, 2006, (ii) the date on which all shares available for issuance under the
Plan shall have been issued as shares or (iii) the termination of all
outstanding options in connection with a Corporate Transaction. If the date of
termination is determined under clause (i) above, then all option grants
outstanding on such date shall thereafter continue to have force and effect in
accordance with the provisions of the instruments evidencing such grants.

         V.          USE OF PROCEEDS

                     Any cash proceeds received by the Corporation from the sale
of shares pursuant to option grants under the Plan shall be used for general
corporate purposes.



                                       20.

<PAGE>   21

         VI.         REGULATORY APPROVALS

                     The implementation of the Plan, the granting of any stock
option or stock appreciation right under the Plan and the issuance of Common
Stock upon the exercise of the stock options or stock appreciation rights
granted hereunder shall be subject to the Corporation's procurement of all
approvals and permits required by regulatory authorities having jurisdiction
over the Plan, the stock options and stock appreciation rights granted under it
and the Common Stock issued pursuant to it.

         VII.        NO EMPLOYMENT/SERVICE RIGHTS

                     Neither the action of the Corporation in establishing the
Plan, nor any action taken by the Plan Administrator hereunder, nor any
provision of the Plan shall be construed so as to grant any individual the right
to remain in the Service of the Corporation (or any Parent or Subsidiary) for
any period of specific duration, and the Corporation (or any Parent or
Subsidiary retaining the services of such individual) may terminate such
individual's Service at any time and for any reason, with or without cause.

         VIII.       MISCELLANEOUS PROVISIONS

                     A. Except to the extent otherwise expressly provided in the
Plan, the right to acquire Common Stock or other assets under the Plan may not
be assigned, encumbered or otherwise transferred by any Optionee.

                     B. The provisions of the Plan relating to the exercise of
options shall be governed by the laws of the State of Texas without resort to
that State's conflict-of-laws rules, as such laws are applied to contracts
entered into and performed in such State.

                     C. The provisions of the Plan shall inure to the benefit
of, and be binding upon, the Corporation and its successors or assigns, whether
by Corporate Transaction or otherwise, and the Optionees, the legal
representatives of their respective estates, their respective heirs or legatees
and their permitted assignees.

                              EMPLOYMENT AGREEMENT



         This Employment Agreement ("Agreement") is entered into as of April 1,
1996 between AMERICAN PHYSICIAN PARTNERS, INC., a Delaware corporation (the
"Company"), and Gregory L. Solomon ("Solomon").

         In consideration of the mutual covenants and conditions set forth
herein, the parties hereby agree as follows:

         1. EMPLOYMENT. The Company hereby employs Solomon in the capacity of
President and Chief Executive Officer. Solomon accepts such employment and
agrees to perform such services as are customary to such office and as shall
from time to time be assigned to him by the Board of Directors.

         2. TERM. The employment hereunder shall be for a period of 1 year,
commencing on April __, 1996 (the "Commencement Date") and shall be
automatically renewed for successive one year periods unless earlier terminated
as provided in Section 5. Solomon's employment will be on a full-time basis
requiring the devotion of such amount of his productive time as is necessary for
the efficient operation of the business of the Company.

         3. COMPENSATION AND BENEFITS

            3.1 SALARY. For the performance of Solomon's duties hereunder, the
Company shall pay Solomon an annual salary of $190,000, payable (less required
withholdings) no less frequently than twice monthly.

            3.2 BONUS. The Company shall also pay Solomon an annual cash bonus
for the first employment year, which bonus shall be payable in a single
installment within 30 days following the end of the employment year for which it
is earned. The annual bonus for the first employment year will be $35,000.
During the first employment year the Board of Directors and Solomon will
establish a mutually acceptable bonus plan for the second and subsequent
employment years, which plan (i) will provide Solomon with appropriate
incentives and the opportunity to earn bonus amounts comparable to those
available to top executive officers of similar companies, and (ii) may base the
bonus awards on the amount of earnings per share for the Company as defined by
Generally Accepted Accounting Principals (GAAP).

            3.3 STOCK OPTIONS. Upon commencement of Solomon's employment
hereunder, the Company shall grant to Solomon options under the Company's Stock
Option Plan to purchase 250,000 shares of the Company's common stock at an
exercise price of $.125 per share. The options will vest in accordance with the
Company's Stock Option Plan and each option will be exercisable for a period of
ten years from the



                                        1

<PAGE>   2

Commencement Date. This option shall become exercisable as to one sixtieth
(1.66667%) of the original option shares at the end of each monthly anniversary
of the grant date over a term of five years. In the event Solomon is employed by
the Company upon the closing of its Initial Public Offering, 50% of Solomon's
then granted options shall become vested. In the event the Initial Public
Offering is completed and 50% of Solomon's then granted options vest, the
remaining options will become exercisable evenly over the remaining months
ending on the fifth anniversary of the Commencement Date. Option shares will not
vest after Termination. Solomon shall be considered for participation in plans
granting additional options or stock awards to top executives.

            3.4 BENEFITS. Solomon shall be entitled to such medical, disability
and life insurance coverage and such vacation, sick leave and holiday benefits,
if any, and any other benefits as are made available to the Company's top
executive personnel, all in accordance with the Company's benefits program in
effect from time to time. The Company will assume Solomon's medical insurance
costs up to $500 per month until Solomon joins the Company provided plan.

            3.5 REIMBURSEMENT OF EXPENSES. Solomon shall be entitled to be
reimbursed for all reasonable expenses, including but not limited to expenses
for travel, meals and entertainment, incurred by Solomon in connection with and
reasonably related to the furtherance of the Company's business.

            3.6 ANNUAL REVIEW. On each anniversary of the Commencement Date, the
Board of Directors will review Solomon's performance and compensation hereunder
(including salary, bonus and stock options and/or other equity incentives) and
will consider whether to increase such compensation, but will not have
authority, as the result of such review, to decrease any portion of such
compensation without the written consent of Solomon.

         4. CHANGE OF CONTROL. In the event of a Change of Control of the
Company (as defined below), all options then granted to Solomon which are
unvested at the date of the Change of Control will be immediately vested. In
addition, notwithstanding the provisions of Section 5.2(b), in the event of a
termination of Solomon's employment hereunder by the Company following a Change
of Control, the Company will promptly pay Solomon, in addition to the amounts
required under Section 5.2(a), a lump sum severance amount, payable immediately
upon such termination of employment, equal to two (2) years of salary at the
then current rate, excluding bonus.

         As used herein, a "Change of Control" of the Company shall be deemed to
have occurred:

            a. Upon the consummation, in one transaction or a series of related
transactions, of the sale or other transfer of voting power (including voting
power exercisable on a contingent or deferred basis as well as immediately
exercisable voting power) representing effective control of the Company to a
person or group of related persons who,



                                        2

<PAGE>   3

on the date of this Agreement, does not have effective voting control of the
Company, whether such sale or transfer results from a tender offer or otherwise;
or

            b. Upon the consummation of a merger or consolidation in which the
Company is a constituent corporation and in which the Company's shareholders
immediately prior thereto will beneficially own, immediately thereafter,
securities of the Company or any surviving or new corporation resulting
therefrom having less than a majority of the voting power of the Company or any
such surviving or new corporation; or

            c. Upon the consummation of a sale, lease, exchange or other
transfer or disposition by the Company of all or substantially all its assets to
any person or group or related persons.

         5. TERMINATION

            5.1 TERMINATION EVENTS. The employment hereunder will terminate upon
the occurrence of any of the following events:

                a. Solomon dies;

                b. the Company, by written notice to Solomon or his personal
representative, discharges Solomon due to the inability to perform the duties
assigned to him hereunder for a continuous period exceeding 120 days by reason
of injury, physical or mental illness or other disability, which condition has
been certified by a physician; provided, however, that prior to discharging
Solomon due to such disability, the Company shall give a written statement of
findings to Solomon or his personal representative setting forth specifically
the nature of the disability and the resulting performance failures, and Solomon
shall have a period of ten (10) days thereafter to respond in writing to the
Board of Directors' findings;

                c. Solomon is discharged by the Board of Directors of the
Company for cause. As used in this Agreement, the term "cause" shall mean:

                  (1) Solomon's conviction of (or pleading guilty or nolo
contendere to) a felony or any misdemeanor involving dishonesty or moral
turpitude; provided, however, that prior to discharging Solomon for cause, the
Company shall give a written statement of findings to Solomon setting forth
specifically the grounds on which cause is based, and Solomon shall have a
period of ten (10) days thereafter to respond in writing to the Board of
Directors' findings;

                  (2) the willful and continued failure of Solomon to
substantially perform his duties with the Company (other than any such failure
resulting from illness or disability) after a written demand for substantial
performance is requested by the Company's Board of Directors, which specifically
identifies the manner in which it is claimed Solomon has not substantially
performed his duties, or Solomon is willfully engaged



                                        3

<PAGE>   4

in misconduct which has, or can reasonably be expected to have, a direct and
material adverse monetary effect on the Company. For purposes of this Section no
act or failure to act on Solomon's part shall be considered "willful" if done,
or omitted to be done, by Solomon in good faith and with reasonable belief that
Solomon's action or omission was in the best interest of the Company. No
termination shall be effected for Cause unless Solomon has been provided with
specific information as to the acts or omissions which form the basis of the
allegation of Cause, and Solomon has had an opportunity to be heard, with
counsel if he so desired, before the Board of Directors and such Board
determines, by majority vote, in good faith that Solomon was guilty of conduct
constituting "Cause" as herein defined, specifying the particulars thereof in
detail.

                d. Solomon is discharged by the Board of Directors of the
Company without cause, which the Company may do at any time, with at least 30
days advance written notice; or

                e. Solomon voluntarily terminates his employment due to either
(i) a default by the Company in the performance of any of its obligations
hereunder, or (ii) an Adverse Change in Duties (as defined below), which default
or Adverse Change in Duties remains unremedied by the Company for a period of
ten days following its receipt of written notice thereof from Solomon; or

                f. Solomon voluntarily terminates his employment for any reason
other than the Company's default or an Adverse Change in Duties, which Solomon
may do at any time with at least 30 days advance notice.

         As used herein, "Adverse Change in Duties" means an action or series of
actions taken by the Company, without Solomon's prior written consent, which
results in:

                  (1) A change in Solomon's reporting responsibilities, titles,
job responsibilities or offices which results in a material diminution of his
status, control or authority; or

                  (2) The assignment to Solomon of any positions, duties or
responsibilities which are materially inconsistent with Solomon's positions,
duties and responsibilities or status with the Company; or

                  (3) A requirement by the Company that Solomon be based or
perform his duties anywhere other than (i) at the Company's corporate office
location on the date of this Agreement, or (ii) if the Company's corporate
office location is moved after the date of this Agreement, at a new location
that is no more than 60 miles from such prior location; or

                  (4) A failure by the Company to provide for Solomon's
participation in any current or future benefits or plans at a level or to an
extent commensurate with that of other top executives of the Company.

            5.2 EFFECTS OF TERMINATION.

                (a) Upon termination of Solomon's employment hereunder for any
reason, the Company will promptly pay Solomon all compensation owed to Solomon
and unpaid through the date of termination (including, without limitation,
salary and employee expense reimbursements).

                (b) In addition, if the employment is terminated under Sections
5.1(b), (d) or (e), the Company shall also pay Solomon, immediately upon such
termination of employment, a lump sum severance amount equal to one-half of the
then applicable annual salary, excluding bonus.

         individual, employee, director, consultant or advisor, or in any other
         capacity whatsoever, provide services to any person, firm, corporation
         or other business enterprise which is involved in the acquisition or
         management of radiology physician practices or other service company
         that directly provides management services in the area of radiology
         where currently operating, unless he obtains the prior written consent
         of the Board of Directors.

                  ii) Solomon will not directly or indirectly encourage or

                              EMPLOYMENT AGREEMENT



         This Employment Agreement ("Agreement") is entered into as of June 12,
1996 between AMERICAN PHYSICIAN PARTNERS, INC., a Delaware corporation (the
"Company"), and Mike Martin ("Martin").

         In consideration of the mutual covenants and conditions set forth
herein, the parties hereby agree as follows:

         1. EMPLOYMENT. The Company hereby employs Martin in the capacity of
Chief Operating Officer. Martin accepts such employment and agrees to perform
such services as are customary to such office and as shall from time to time be
assigned to him by the Board of Directors.

         2. TERM. The employment hereunder shall be for a period of 1 year,
commencing on June 12, 1996 (the "Commencement Date") and shall be automatically
renewed for successive one year periods unless earlier terminated as provided in
Section 5. Martin's employment will be on a full-time basis requiring the
devotion of such amount of his productive time as is necessary for the efficient
operation of the business of the Company.

         3. COMPENSATION AND BENEFITS

            3.1 SALARY. For the performance of Martin's duties hereunder, the
Company shall pay Martin an annual salary of $160,000, payable (less required
withholdings) no less frequently than twice monthly.

            3.2 BONUS. The Company shall also pay Martin an annual cash bonus
for the first employment year, which bonus shall be payable in a single
installment within 30 days following the end of the employment year for which it
is earned. The annual bonus for the first employment year will be $30,000.
During the first employment year the Board of Directors and Martin will
establish a mutually acceptable bonus plan for the second and subsequent
employment years, which plan (i) will provide Martin with appropriate incentives
and the opportunity to earn bonus amounts comparable to those available to top
executive officers of similar companies, and (ii) may base the bonus awards on
the amount of earnings per share for the Company as defined by Generally
Accepted Accounting Principals (GAAP).

            3.3 STOCK OPTIONS. Upon commencement of Martin's employment
hereunder, the Company shall grant to Martin options under the Company's Stock
Option Plan to purchase 180,000 shares of the Company's common stock at an
exercise price of $.125 per share. The options will vest in accordance with the
Company's Stock Option Plan and each option will be exercisable for a period of
ten years from the Commencement Date.



                                        1

<PAGE>   2

This option shall become exercisable as to one sixtieth (1.66667%) of the
original option shares at the end of each monthly anniversary of the grant date
over a term of five years. In the event Martin is employed by the Company upon
the closing of its Initial Public Offering, 50% of Martin's then granted options
shall become vested. In the event the Initial Public Offering is completed and
50% of Martin's then granted options vest, the remaining options will become
exercisable evenly over the remaining months ending on the fifth anniversary of
the Commencement Date. Option shares will not vest after Termination. Martin
shall be considered for participation in plans granting additional options or
stock awards to top executives.

            3.4 BENEFITS. Martin shall be entitled to such medical, disability
and life insurance coverage and such vacation, sick leave and holiday benefits,
if any, and any other benefits as are made available to the Company's top
executive personnel, all in accordance with the Company's benefits program in
effect from time to time. The Company will assume Martin's medical insurance
costs up to $500 per month until Martin joins the Company provided plan.

            3.5 REIMBURSEMENT OF EXPENSES. Martin shall be entitled to be
reimbursed for all reasonable expenses, including but not limited to expenses
for travel, meals and entertainment, incurred by Martin in connection with and
reasonably related to the furtherance of the Company's business.

            3.6 RELOCATION EXPENSES. The Company will reimburse Martin for
reasonable relocation costs incurred by Martin in connection with his relocation
to the Dallas area.

            3.7 ANNUAL REVIEW. On each anniversary of the Commencement Date, the
Board of Directors will review Martin's performance and compensation hereunder
(including salary, bonus and stock options and/or other equity incentives) and
will consider whether to increase such compensation, but will not have
authority, as the result of such review, to decrease any portion of such
compensation without the written consent of Martin.

         4. CHANGE OF CONTROL. In the event of a Change of Control of the
Company (as defined below), all options then granted to Martin which are
unvested at the date of the Change of Control will be immediately vested. In
addition, notwithstanding the provisions of Section 5.2(b), in the event of a
termination of Martin's employment hereunder by the Company following a Change
of Control, the Company will promptly pay Martin, in addition to the amounts
required under Section 5.2(a), a lump sum severance amount, payable immediately
upon such termination of employment, equal to two (2) years of salary at the
then current rate, excluding bonus.

         As used herein, a "Change of Control" of the Company shall be deemed to
have occurred:



                                        2

<PAGE>   3

                a. Upon the consummation, in one transaction or a series of
related transactions, of the sale or other transfer of voting power (including
voting power exercisable on a contingent or deferred basis as well as
immediately exercisable voting power) representing effective control of the
Company to a person or group of related persons who, on the date of this
Agreement, does not have effective voting control of the Company, whether such
sale or transfer results from a tender offer or otherwise; or

                b. Upon the consummation of a merger or consolidation in which
the Company is a constituent corporation and in which the Company's shareholders
immediately prior thereto will beneficially own, immediately thereafter,
securities of the Company or any surviving or new corporation resulting
therefrom having less than a majority of the voting power of the Company or any
such surviving or new corporation; or

                c. Upon the consummation of a sale, lease, exchange or other
transfer or disposition by the Company of all or substantially all its assets to
any person or group or related persons.

         5. TERMINATION

            5.1 TERMINATION EVENTS. The employment hereunder will terminate upon
the occurrence of any of the following events:

                a. Martin dies;

                b. the Company, by written notice to Martin or his personal
representative, discharges Martin due to the inability to perform the duties
assigned to him hereunder for a continuous period exceeding 120 days by reason
of injury, physical or mental illness or other disability, which condition has
been certified by a physician; provided, however, that prior to discharging
Martin due to such disability, the Company shall give a written statement of
findings to Martin or his personal representative setting forth specifically the
nature of the disability and the resulting performance failures, and Martin
shall have a period of ten (10) days thereafter to respond in writing to the
Board of Directors' findings;

                c. Martin is discharged by the Board of Directors of the Company
for cause. As used in this Agreement, the term "cause" shall mean:

                   (1) Martin's conviction of (or pleading guilty or nolo
contendere to) a felony or any misdemeanor involving dishonesty or moral
turpitude; provided, however, that prior to discharging Martin for cause, the
Company shall give a written statement of findings to Martin setting forth
specifically the grounds on which cause is based, and shall have a period of ten
(10) days thereafter to respond in writing to the Board of Directors' findings;

                   (2) the willful and continued failure of Martin to
substantially perform his duties with the Company (other than any such failure
resulting from



                                        3

<PAGE>   4

illness or disability) after a written demand for substantial performance is
requested by the Company's Board of Directors, which specifically identifies the
manner in which it is claimed Martin has not substantially performed his duties,
or Martin is willfully engaged in misconduct which has, or can reasonably be
expected to have, a direct and material adverse monetary effect on the Company.
For purposes of this Section no act or failure to act on Martin's part shall be
considered "willful" if done, or omitted to be done, by Martin in good faith and
with reasonable belief that Martin's action or omission was in the best interest
of the Company. No termination shall be effected for Cause unless Martin has
been provided with specific information as to the acts or omissions which form
the basis of the allegation of Cause, and Martin has had an opportunity to be
heard, with counsel if he so desired, before the Board of Directors and such
Board determines, by majority vote, in good faith that Martin was guilty of
conduct constituting "Cause" as herein defined, specifying the particulars
thereof in detail;

                d. Martin is discharged by the Board of Directors of the Company
without cause, which the Company may do at any time, with at least 30 days
advance written notice; or

                e. Martin voluntarily terminates his employment due to either
(i) a default by the Company in the performance of any of its obligations
hereunder, or (ii) an Adverse Change in Duties (as defined below), which default
or Adverse Change in Duties remains unremedied by the Company for a period of
ten days following its receipt of written notice thereof from Martin; or

                f. Martin voluntarily terminates his employment for any reason
other than the Company's default or an Adverse Change in Duties, which Martin
may do at any time with at least 30 days advance notice.

         As used herein, "Adverse Change in Duties" means an action or series of
actions taken by the Company, without Martin's prior written consent, which
results in:

                   (1) A change in Martin's reporting responsibilities, titles,
job responsibilities or offices which results in a material diminution of his
status, control or authority; or

                   (2) The assignment to Martin of any positions, duties or
responsibilities which are materially inconsistent with Martin's positions,
duties and responsibilities or status with the Company; or

                   (3) A requirement by the Company that Martin be based or
perform his duties anywhere other than (i) at the Company's corporate office
location on the date of this Agreement, or (ii) if the Company's corporate
office location is moved after the date of this Agreement, at a new location
that is no more than 60 miles from such prior location; or



                                        4

<PAGE>   5

                   (4) A failure by the Company to provide for Martin's
participation in any current or future benefits or plans at a level or to an
extent commensurate with that of other top executives of the Company.

            5.2 EFFECTS OF TERMINATION.

                (a) Upon termination of Martin's employment hereunder for any
reason, the Company will promptly pay Martin all compensation owed to Martin and
unpaid through the date of termination (including, without limitation, salary
and employee expense reimbursements).

                (b) In addition, if the employment is terminated under Sections
5.1(b), (d) or (e), the Company shall also pay Martin, immediately upon such
termination of employment, a lump sum severance amount equal to one-half of the
then applicable annual salary, excluding bonus.

                (c) Upon termination of Martin's employment hereunder for any
reason, Martin agrees that for the one year period following the Termination
Event:

                  i) Martin will not directly or indirectly, whether as an
         individual, employee, director, consultant or advisor, or in any other
         capacity whatsoever, provide services to any person, firm, corporation
         or other business enterprise which is involved in the acquisition and
         management of radiology physician practices where currently operating,
         unless he obtains the prior written consent of the Board of Directors.

                  ii) Martin will not directly or indirectly encourage or
         solicit, or attempt to encourage or solicit, any individual to leave
         the Company's employ for any reason or interfere in any other manner
         with the employment relationships at the time existing between the
         Company and its current or prospective employees.

                  iii) Martin will not induce or attempt to induce any provider,
         payor, customer, supplier, distributor, licensee or other business
         relation of the Company to cease doing business with the Company or in
         any way interfere with the existing business relationship between any
         such customer, supplier, distributor, licensee or other business
         relation and the Company.

         Martin acknowledges that monetary damages may not be sufficient to
compensate the Company for any economic loss which may be incurred by reason of
breach of the foregoing restrictive covenants. Accordingly, in the event of any
such breach, the Company shall, in addition to any remedies available to the
Company at law, be entitled to obtain equitable relief in the form of an
injunction precluding Martin from continuing to engage in such breach.



                                        5

<PAGE>   6

unreasonable, then Martin and the Company agree, and hereby submit, to the
reduction and limitation of such prohibition to such area or period as shall be
deemed reasonable.

between the parties with respect to the subject matter hereof and supersedes any
and all prior agreements between the parties relating to such subject matter.

costs up to $500 per month until Abbasi joins the Company provided plan.

            3.5 REIMBURSEMENT OF EXPENSES. Abbasi shall be entitled to be

Board of Directors will review Abbasi's performance and compensation hereunder
(including salary, bonus and stock options and/or other equity incentives) and
will consider whether to increase such compensation, but will not have
authority, as the result of such review, to decrease any portion of such
compensation without the written consent of Abbasi.

         4. CHANGE OF CONTROL. In the event of a Change of Control of the
Company (as defined below), all options then granted to Abbasi which are
unvested at the date of the Change of Control will be immediately vested. In
addition, notwithstanding the provisions of Section 5.2(b), in the event of a
termination of Abbasi's employment hereunder by the Company following a Change
of Control, the Company will promptly pay Abbasi, in addition to the amounts
required under Section 5.2(a), a lump sum severance amount, payable immediately
upon such termination of employment, equal to two (2) years of salary at the
then current rate, excluding bonus.

         As used herein, a "Change of Control" of the Company shall be deemed to

            a. Upon the consummation, in one transaction or a series of related

power exercisable on a contingent or deferred basis as well as immediately
exercisable voting power) representing effective control of the Company to a
person or group of related persons who, on the date of this Agreement, does not
have effective voting control of the Company, whether such sale or transfer
results from a tender offer or otherwise; or

            b. Upon the consummation of a merger or consolidation in which the
Company is a constituent corporation and in which the Company's shareholders
immediately prior thereto will beneficially own, immediately thereafter,
securities of the Company or any surviving or new corporation resulting

such surviving or new corporation, or

            c. Upon the consummation of a sale, lease, exchange or other
transfer or disposition by the Company of all or substantially all its assets to
any person or group or related persons.

         5. TERMINATION

            5.1 TERMINATION EVENTS. The employment hereunder will terminate upon
the occurrence of any of the following events:

            a. Abbasi dies;

            b. the Company, by written notice to Abbasi or his personal
representative, discharges Abbasi due to the inability to perform the duties
assigned to him hereunder for a continuous period exceeding 120 days by reason
of injury, physical or mental illness or other disability, which condition has
been certified by a physician; provided, however, that prior to discharging
Abbasi due to such disability, the Company shall give a written statement of
findings to Abbasi or his personal representative setting forth specifically the
nature of the disability and the resulting performance failures, and Abbasi
shall have a period of ten (10) days thereafter to respond in writing to the
Board of Directors' findings;

            c. Abbasi is discharged by the Board of Directors of the Company for
cause. As used in this Agreement, the term "cause" shall mean:

                (1) Abbasi's conviction of (or pleading guilty or nolo
contendere to) a felony or any misdemeanor involving dishonesty or moral
turpitude; provided, however, that prior to discharging Abbasi for cause, the
Company shall give a written statement of findings to Abbasi setting forth
specifically the grounds on which cause is basedm and Abbasi shall have a period
of ten (10) days thereafter to respond in writing to the Board of Directors'
findings;

                (2) the willful and continued failure of Abbasi to substantially
perform his duties with the Company (other than any such failure resulting from



                                        3

<PAGE>   4

illness or disability) after a written demand for substantial performance is
requested by the Company's Board of Directors, which specifically identifies the
manner in which it is claimed Abbasi has not substantially performed his duties,
or Abbasi is willfully engaged in misconduct which has, or can reasonably be
expected to have, a direct and material adverse monetary effect on the Company.
For purposes of this Section no act or failure to act on Abbasi's part shall be
considered "willful" if done, or omitted to be done, by Abbasi in good faith and
with reasonable belief that Abbasi's action or omission was in the best interest
of the Company. No termination shall be effected for Cause unless Abbasi has
been provided with specific information as to the acts or omissions which form
the basis of the allegation of Cause, and Abbasi has had an opportunity to be
heard, with counsel if he so desired, before the Board of Directors and such
Board determines, by majority vote, in good faith that Abbasi was guilty of
conduct constituting "Cause" as herein defined, specifying the particulars
thereof in detail;

            d. Abbasi is discharged by the Board of Directors of the Company
without cause, which the Company may do at any time, with at least 30 days
advance written notice; or

            e. Abbasi voluntarily terminates his employment due to either (i) a
default by the Company in the performance of any of its obligations hereunder,
or (ii) an Adverse Change in Duties (as defined below), which default or Adverse
Change in Duties remains unremedied by the Company for a period of ten days
following its receipt of written notice thereof from Abbasi; or

            f. Abbasi voluntarily terminates his employment for any reason other
than the Company's default or an Adverse Change in Duties, which Abbasi may do
at any time with at least 30 days advance notice.

         As used herein, "Adverse Change in Duties" means an action or series of
actions taken by the Company, without Abbasi's prior written consent, which
results in:

                (1) A change in Abbasi's reporting responsibilities, titles, job
responsibilities or offices which results in a material diminution of his
status, control or authority; or

                (2) The assignment to Abbasi of any positions, duties or
responsibilities which are materially inconsistent with Abbasi's positions,
duties and responsibilities or status with the Company; or

                (3) A requirement by the Company that Abbasi be based or perform
his duties anywhere other than (i) at the Company's corporate office location on
the date of this Agreement, or (ii) if the Company's corporate office location
is moved after the date of this Agreement, at a new location that is no more
than 60 miles from such prior location; or



                                        4

<PAGE>   5

                (4) A failure by the Company to provide for Abbasi's
participation in any current or future benefits or plans at a level or to an
extent commensurate with that of other top executives of the Company.

            5.2 EFFECTS OF TERMINATION.

                (a) Upon termination of Abbasi's employment hereunder for any
reason, the Company will promptly pay Abbasi all compensation owed to Abbasi and
unpaid through the date of termination (including, without limitation, salary
and employee expense reimbursements).

                (b) In addition, if the employment is terminated under Sections
5.1(b), (d) or (e), the Company shall also pay Abbasi, immediately upon such
termination of employment, a lump sum severance amount equal to one-half of the
then applicable annual salary, excluding bonus.

                (c) Upon termination of Abbasi's employment hereunder for any
reason, Abbasi agrees that for the one year period following the Termination
Event:

                  i) Abbasi will not directly or indirectly, whether as an
         individual, employee, director, consultant or advisor, or in any other
         capacity whatsoever, provide services to any person, firm, corporation
         or other business enterprise which is involved in the acquisition or
         management of radiology physician practices or other service company
         that directly provides management services in the area of radiology
         where currently operating, unless he obtains the prior written consent
         of the Board of Directors.

                  ii) Abbasi will not directly or indirectly encourage or
         solicit, or attempt to encourage or solicit, any individual to leave
         the Company's employ for any reason or interfere in any other manner
         with the employment relationships at the time existing between the
         Company and its current or prospective employees.

                  iii) Abbasi will not induce or attempt to induce any provider,
         payor, customer, supplier, distributor, licensee or other business
         relation of the Company to cease doing business with the Company or in
         any way interfere with the existing business relationship between any
         such customer, supplier, distributor, licensee or other business
         relation and the Company.

         Abbasi acknowledges that monetary damages may not be sufficient to
compensate the Company for any economic loss which may be incurred by reason of
breach of the foregoing restrictive covenants. Accordingly, in the event of any
such breach, the Company shall, in addition to any remedies available to the
Company at law, be entitled to obtain equitable relief in the form of an
injunction precluding Abbasi from continuing to engage in such breach.



                                        5

         If any restriction set forth in this paragraph is held to be
unreasonable, then Abbasi and the Company agree, and hereby submit, to the
reduction and limitation of such prohibition to such area or period as shall be
deemed reasonable.

                              EMPLOYMENT AGREEMENT



         This Employment Agreement ("Agreement") is entered into as of July 31,
1996 between AMERICAN PHYSICIAN PARTNERS, INC., a Delaware corporation (the
"Company"), and Paul Jolas ("Jolas").

         In consideration of the mutual covenants and conditions set forth
herein, the parties hereby agree as follows:

         1. EMPLOYMENT. The Company hereby employs Jolas in the capacity of
General Counsel and Senior Vice President, reporting directly to the CEO. Jolas
accepts such employment and agrees to perform such services as are customary to
such office and as shall from time to time be assigned to him by the Board of
Directors.

         2. TERM. The employment hereunder shall be for a period of 1 year,
commencing on August 1, 1996 (the "Commencement Date") and shall be
automatically renewed for successive one year periods unless earlier terminated
as provided in Section 5. Jolas's employment will be on a full-time basis
requiring the devotion of such amount of his productive time as is necessary for
the efficient operation of the business of the Company.

         3. COMPENSATION AND BENEFITS

            3.1 SALARY. For the performance of Jolas's duties hereunder, the
Company shall pay Jolas an annual salary of $140,000, payable (less required
withholdings) no less frequently than twice monthly.

            3.2 BONUS. The Company shall also pay Jolas an annual cash bonus for
the first employment year, which bonus shall be payable in a single installment
within 30 days following the end of the employment year for which it is earned.
The annual bonus for the first employment year will be $10,000. During the first
employment year the Board of Directors and Jolas will establish a mutually
acceptable bonus plan for the second and subsequent employment years, which plan
(i) will provide Jolas with appropriate incentives and the opportunity to earn
bonus amounts comparable to those available to top executive officers of similar
companies, and (ii) may base the bonus awards on the amount of earnings per
share for the Company as defined by Generally Accepted Accounting Principals
(GAAP).


            3.3 STOCK OPTIONS. Upon commencement of Jolas's employment
hereunder, the Company shall grant to Jolas options under the Company's Stock
Option Plan to purchase 140,000 shares of the Company's common stock at an
exercise price of $.125 per share. The options will vest in accordance with the
Company's Stock Option Plan and each option will be exercisable for a period of
ten years from the Commencement Date. This option shall become exercisable as to
one sixtieth (1.66667%) of the original option



                                        1

<PAGE>   2

shares at the end of each monthly anniversary of the grant date over a term of
five years. In the event Jolas is employed by the Company upon the closing of
its Initial Public Offering, 25% of Jolas's then granted options shall become
vested. In the event the Initial Public Offering is completed and 25% of Jolas's
then granted options vest, the remaining options will become exercisable evenly
over the remaining months ending on the fifth anniversary of the Commencement
Date. Option shares will not vest after Termination. Jolas shall be considered
for participation in plans granting additional options or stock awards to top
executives.

            3.4 BENEFITS. Jolas shall be entitled to such medical, disability
and life insurance coverage and such vacation, sick leave and holiday benefits,
if any, and any other benefits as are made available to the Company's top
executive personnel, all in accordance with the Company's benefits program in
effect from time to time. The Company will assume Jolas's medical insurance
costs up to $500 per month until Jolas joins the Company provided plan.

            3.5 REIMBURSEMENT OF EXPENSES. Jolas shall be entitled to be
reimbursed for all reasonable expenses, including but not limited to expenses
for travel, meals and entertainment, incurred by Jolas in connection with and
reasonably related to the furtherance of the Company's business.

            3.6 ANNUAL REVIEW. On each anniversary of the Commencement Date, the
Board of Directors will review Jolas's performance and compensation hereunder
(including salary, bonus and stock options and/or other equity incentives) and
will consider whether to increase such compensation, but will not have
authority, as the result of such review, to decrease any portion of such
compensation without the written consent of Jolas.

            3.7 CONTINUING PROFESSIONAL EDUCATION. Employer shall pay for or
reimburse Jolas for all expenses incurred by Jolas in furtherance of Jolas's
duties hereunder, including, but not limited to (i) all taxes, fees, duties,
assessments, licenses, permits and franchises, applicable to attorneys licensed
to practice law in the jurisdictions where Jolas currently is, or may be
required to be, licensed to practice law, (ii) all fees, dues, assessments, and
other costs associated with Jolas's membership in all bar associations,
sections, and other professional organizations and groups, and (iii) all
expenses associated with Jolas's attendance at or participation in continuing
legal education seminars, programs or events, including, but not limited to,
travel, lodging, tuition, books, meals, and other expenses relating to such
continuing legal education events. Jolas's attendance at such continuing legal
events shall not be deemed or accounted for as vacation or personal days/time.

         4. CHANGE OF CONTROL. In the event of a Change of Control of the
Company (as defined below), all options then granted to Jolas which are unvested
at the date of the Change of Control will be immediately vested. In addition,
notwithstanding the provisions of Section 5.2(b), in the event of a termination
of Jolas's employment hereunder by the Company following a Change of Control,
the Company will promptly pay Jolas, in

<PAGE>   3

addition to the amounts required under Section 5.2(a), a lump sum severance
amount, payable immediately upon such termination of employment, equal to two
(2) years of salary at the then current rate, excluding bonus.

         As used herein, a "Change of Control" of the Company shall be deemed to
have occurred:

            a. Upon the consummation, in one transaction or a series of related

results from a tender offer or otherwise; or

            b. Upon the consummation of a merger or consolidation in which the
Company is a constituent corporation and in which the Company's shareholders
immediately prior thereto will beneficially own, immediately thereafter,
securities of the Company or any surviving or new corporation resulting
therefrom having less than a majority of the voting power of the Company or any
such surviving or new corporation; or

            c. Upon the consummation of a sale, lease, exchange or other
transfer or disposition by the Company of all or substantially all its assets to
any person or group or related persons.

         5. TERMINATION

            5.1 TERMINATION EVENTS. The employment hereunder will terminate upon
the occurrence of any of the following events:

            a. Jolas dies;

            b. the Company, by written notice to Jolas or his personal
representative, discharges Jolas due to the inability to perform the duties
assigned to him hereunder for a continuous period exceeding 120 days by reason
of injury, physical or mental illness or other disability, which condition has
been certified by a physician; provided, however, that prior to discharging
Jolas due to such disability, the Company shall give a written statement of
findings to Jolas or his personal representative setting forth specifically the
nature of the disability and the resulting performance failures, and Jolas shall
have a period of ten (10) days thereafter to respond in writing to the Board of
Directors' findings;

            c. Jolas is discharged by the Board of Directors of the Company for
cause. As used in this Agreement, the term "cause" shall mean:

                (1) Jolas's conviction of (or pleading guilty or nolo contendere
to) a felony or any misdemeanor involving dishonesty or moral turpitude;



                                        3

<PAGE>   4

provided, however, that prior to discharging Jolas for cause, the Company shall
give a written statement of findings to Jolas setting forth specifically the
grounds on which cause is based, and Jolas shall have a period of ten (10) days
thereafter to respond in writing to the Board of Directors' findings;

                (2) the willful and continued failure of Jolas to substantially
perform his duties with the Company (other than any such failure resulting from
illness or disability) after a written demand for substantial performance is
requested by the Company's Board of Directors, which specifically identifies the
manner in which it is claimed Jolas has not substantially performed his duties,
or Jolas is willfully engaged in misconduct which has, or can reasonably be
expected to have, a direct and material adverse monetary effect on the Company.
For purposes of this Section no act or failure to act on Jolas's part shall be
considered "willful" if done, or omitted to be done, by Jolas in good faith and
with reasonable belief that Jolas's action or omission was in the best interest
of the Company. No termination shall be effected for Cause unless Jolas has been
provided with specific information as to the acts or omissions which form the
basis of the allegation of Cause, and Jolas has had an opportunity to be heard,
with counsel if he so desired, before the Board of Directors and such Board
determines, by majority vote, in good faith that Jolas was guilty of conduct
constituting "Cause" as herein defined, specifying the particulars thereof in
detail;

            d. Jolas is discharged by the Board of Directors of the Company
without cause, which the Company may do at any time, with at least 30 days
advance written notice; or

            e. Jolas voluntarily terminates his employment due to either (i) a
default by the Company in the performance of any of its obligations hereunder,
or (ii) an Adverse Change in Duties (as defined below), which default or Adverse

following its receipt of written notice thereof from Jolas; or

            f. Jolas voluntarily terminates his employment for any reason other
than the Company's default or an Adverse Change in Duties, which Jolas may do at
any time with at least 30 days advance notice.

         As used herein, "Adverse Change in Duties" means an action or series of
actions taken by the Company, without Jolas's prior written consent, which
results in:

                (1) A change in Jolas's reporting responsibilities, titles, job
responsibilities or offices which results in a material diminution of his
status, control or authority; or

                (2) The assignment to Jolas of any positions, duties or
responsibilities which are materially inconsistent with Jolas's positions,
duties and responsibilities or status with the Company; or

extent commensurate with that of other top executives of the Company.

reason, the Company will promptly pay Jolas all compensation owed to Jolas and
unpaid through the date of termination (including, without limitation, salary
and employee expense reimbursements).

                (b) In addition, if the employment is terminated under Sections
5.1(b), (d) or (e), the Company shall also pay Jolas, immediately upon such
termination of employment, a lump sum severance amount equal to one-half of the
then applicable annual salary, excluding bonus.

                (c) Upon termination of Jolas's employment hereunder for any
reason, Jolas agrees that for the one year period following the Termination
Event:

                  i) Jolas will not directly or indirectly, whether as an
         individual, employee, director, consultant or advisor, or in any other

                  iii) Jolas will not induce or attempt to induce any provider,
         payor, customer, supplier, distributor, licensee or other business
         relation of the Company to cease doing business with the Company or in
         any way interfere with the existing business relationship between any
         such customer, supplier, distributor, licensee or other business
         relation and the Company.

         Jolas acknowledges that monetary damages may not be sufficient to
compensate the Company for any economic loss which may be incurred by reason of
breach of the foregoing restrictive covenants. Accordingly, in the event of any
such breach, the Company shall, in addition to any remedies available to the
Company at law, be entitled to obtain equitable relief in the form of an
injunction precluding Jolas from continuing to engage in such breach.

         If any restriction set forth in this paragraph is held to be
unreasonable, then Jolas and the Company agree, and hereby submit, to the
reduction and limitation of such prohibition to such area or period as shall be
deemed reasonable.

                           INDEMNIFICATION AGREEMENT


                 This INDEMNIFICATION AGREEMENT (the "Agreement") is entered
into this ___ day of ___________, 1997, by and between AMERICAN PHYSICIAN
PARTNERS, INC., a Delaware corporation ("APP"), and the individuals identified
on Exhibit A attached hereto (the "Stockholders").  Unless otherwise defined
herein, all capitalized terms shall have the meaning contained in that certain
Agreement and Plan of Reorganization and Merger dated ______________, 1997 (the
"Merger Agreement") by and among APP, APP Sub and _________________________, a
_____________ corporation (the "Company").

                                    RECITALS

                 A.       Concurrent with this Agreement, the Company shall
enter into the Merger Agreement and the Service Agreement whereby APP shall
acquire the assets, and manage the non-medical aspects of, the Company's
radiology practice.

                 B.       Pursuant to Section ____ of the Merger Agreement, the
Stockholders have, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, agreed to execute and deliver
this Agreement to APP and APP Sub.

                 NOW, THEREFORE, in consideration of the preceding recitals and
the covenants and agreements set forth herein, the parties agree as follows:

         1.      Indemnification by the Stockholders.  Subject to the terms,
limitations and conditions of this Agreement, the Stockholders (each an
"Indemnifying Party" and collectively, the "Indemnifying Parties"), severally,
and not jointly, agree to indemnify, defend and hold APP and its directors,
officers, stockholders, employees, agents, attorneys, consultants and
Affiliates (each an "Indemnified Party" and collectively, the "Indemnified
Parties"), harmless from and against all losses, claims, obligations, demands,
assessments, penalties, liabilities, costs, damages, reasonable attorneys' fees
and expenses (including, without limitation, all costs of experts and all costs
incidental to or in connection with any appellate process) (collectively,
"Damages") asserted against or incurred by an Indemnified Party arising out of
or resulting from:

                 a.       a breach of any representation, warranty or covenant
of the Company contained in the Merger Agreement (without giving effect to any
Material Adverse Effect qualifier contained as part of any such representation
or warranty or covenant of the Company contained in the Merger Agreement or in
any Disclosure Schedule or certificate delivered thereunder);

                 b.       any violation (or alleged violation) by the Company
and/or any of its past or present directors, officers, partners, stockholders,
employees (including, without limitation, any Physician Employee), agents,
attorneys, consultants and Affiliates of any state or federal law governing
health care fraud and abuse or prohibition on referral of patients to Persons
in which a licensed professional has a financial or other form of interest
(including, but not limited to, fraud and abuse in the Medicare and Medicaid
Programs) occurring on or before the Closing Date, or any overpayment or
obligation (or alleged overpayment or obligation) arising out of or resulting
from claims submitted to any Payor on or before the Closing Date; and



                                       1
<PAGE>   2
                 c.       any liability under the Securities Act, the Exchange
Act or any other federal or state "blue sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any (i) untrue
statement of a material fact in any Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto relating
to the Company (including any Company Subsidiary) or NewCo or (ii) failure to
state information necessary to make the statements required to be stated
therein not misleading, which untrue statement or failure to state information
arises or results solely from information provided in writing to APP or its
counsel by the Company or such Stockholder or their agents specifically for
inclusion in any such Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto (including, without
limitation, schedules, exhibits and certifications delivered by the Company or
any of its agents in connection with the Merger Agreement).

                 The provisions contained in Paragraph 2(g) shall not apply to
indemnification of claims listed in Exhibit B attached hereto.  In addition,
notwithstanding anything herein to the contrary, nothing contained in this
Agreement shall relieve any of the Stockholders of any liability or limit any
liability that he or she may have in the case of fraud in connection with the
transactions contemplated by the Merger Agreement.

         2.      Conditions of Indemnification.  All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

                 a.       The Indemnified Party shall promptly (and, in any
event, at least ten (10) days prior to the due date for any responsive
pleadings, filings or other documents) (i) notify each Indemnifying Party of
any third-party claim or claims asserted against the Indemnified Party ("Third
Party Claim") that could give rise to a right of indemnification under this
Agreement and (ii) transmit to the Indemnifying Parties a written notice
("Claim Notice") describing in reasonable detail the nature of the Third Party
Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of Damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement.  The failure to promptly deliver a Claim Notice shall not relieve
any Indemnifying Party of its obligations to any Indemnified Party with respect
to the related Third Party Claim except to the extent that the resulting delay
is materially prejudicial to the defense of such claim.  Within thirty (30)
days after receipt of any Claim Notice (the "Election Period"), the
Indemnifying Parties shall notify the Indemnified Party (x) whether the
Indemnifying Parties dispute their potential liability to the Indemnified Party
under this Agreement with respect to such Third Party Claim and (y) whether the
Indemnifying Parties desire, at the sole cost and expense of each Indemnifying
Party, to defend the Indemnified Party against such Third Party Claim.

                 b.       If the Indemnifying Parties notify the Indemnified
Party within the Election Period that the Indemnifying Parties elect to assume
the defense of the Third Party Claim, then the Indemnifying Parties shall have
the right to defend, at their sole cost and expense, with counsel reasonably
acceptable to such Indemnified Party or Indemnified Parties, such Third Party
Claim by all appropriate proceedings, which proceedings shall be prosecuted
diligently by the Indemnifying Parties to a final conclusion or settled at the
discretion of the Indemnifying Parties in accordance with this Paragraph 2(b).
Except as set forth in Paragraph 2(f) below, the Indemnifying Parties shall
have full control of such defense and proceedings, including any compromise or
settlement thereof.  The Indemnified Party is hereby authorized, at the sole
cost and expense of the Indemnifying Parties (but only if the Indemnified Party
is entitled to indemnification hereunder), to file, during the Election Period,
any motion, answer or other pleadings that the Indemnified Party shall deem
necessary or appropriate to protect its interests or those of the Indemnifying
Parties and not prejudicial to the Indemnifying Parties.  If requested by the
Indemnifying





                                       2
<PAGE>   3
Parties, the Indemnified Party agrees, at the sole cost and expense of the
Indemnifying Parties, to cooperate with the Indemnifying Parties and their
counsel in contesting any Third Party Claim that the Indemnifying Parties elect
to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person.  The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Parties pursuant to this Paragraph 2(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Parties and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Parties, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Parties, and upon written
notification thereof, the Indemnifying Parties shall not have the right to
assume the defense of such action on behalf of the Indemnified Party; provided
further that the Indemnifying Parties shall not, in connection with any one
such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm
of attorneys at any time for the Indemnified Party, which firm shall be
designated in writing by the Indemnified Party.  Notwithstanding the foregoing,
the Indemnifying Parties shall be prohibited from confessing or settling any
criminal allegations brought against the Indemnified Party without the express
written consent of the Indemnified Party.

                 c.       If the Indemnifying Parties fail to notify the
Indemnified Party within the Election Period that the Indemnifying Parties
elect to defend the Indemnified Party pursuant to Paragraph 2(b), or if the
Indemnifying Parties elect to defend the Indemnified Party pursuant to
Paragraph 2(b) but fail diligently and promptly to prosecute or settle the
Third Party Claim, then the Indemnified Party shall have the right to defend,
at the sole cost and expense of the Indemnifying Parties (if the Indemnified
Party is entitled to indemnification hereunder), the Third Party Claim by all
appropriate proceedings, which proceedings shall be promptly and vigorously
prosecuted by the Indemnified Parties to a final conclusion or settled.  The
Indemnified Parties shall have full control of such defense and proceedings,
provided, however, that the Indemnified Parties may not enter into, without the
Indemnifying Parties' consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim.  Notwithstanding the
foregoing, if the Indemnifying Parties have delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Parties dispute their
potential liability to the Indemnified Party under this Agreement and if such
dispute is resolved in favor of the Indemnifying Parties, the Indemnifying
Parties shall not be required to bear the costs and expenses of the Indemnified
Parties' defense pursuant to this Paragraph or of the Indemnifying Party's
participation therein at the Indemnified Party's request, and the Indemnified
Party shall reimburse the Indemnifying Parties in full for all costs and
expenses of such litigation.  The Indemnifying Parties may participate in, but
not control, any defense or settlement controlled by the Indemnified Party
pursuant to this Paragraph 2(c), and the Indemnifying Parties shall bear their
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnifying Parties have been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnified Party, then the Indemnifying Parties may employ
separate counsel and upon written notification thereof, the Indemnified Party
shall not have the right to assume the defense of such action on behalf of the
Indemnifying Parties.

                 d.       In the event any Indemnified Party should have a
claim against any Indemnifying Parties hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Parties a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature





                                       3
<PAGE>   4
of the claim, an estimate of the amount of damages attributable to such claim
and the basis of the Indemnified Party's request for indemnification under this
Agreement.  If the Indemnifying Parties do not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Parties dispute such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Parties hereunder.  If the Indemnifying Parties have timely disputed such
claim, as provided above, such dispute shall be resolved by the procedures set
forth in Paragraph 7.

                 e.       Payments of all amounts owing by any Indemnifying
Party pursuant to this Agreement relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Parties liability to the
Indemnified Party under this Agreement.  Payments of all amounts owing by the
Indemnifying Parties pursuant to Paragraph 2(d) shall be made within thirty
(30) days after the later of (i) the expiration of the 60-day Indemnity Notice
period or (ii) the expiration of the period for appeal of a final adjudication
of the Indemnifying Parties liability to the Indemnified Party under this
Agreement.

                          (1)     Within five (5) business days following
distribution by APP of a Claim Notice or Indemnity Notice, as the case may be,
each Stockholder shall elect the percentage of APP Common Stock he or she
desires to allocate (the "Stock Percentage Election") to satisfy any obligation
to APP contained in the Claim Notice or Indemnity Notice (the "Indemnification
Obligation") and shall submit such Stock Percentage Election in writing to APP
at the address listed in Paragraph 8 hereof or any other address requested by
APP.  Each Stockholder shall be entitled to make a Stock Percentage Election
equal to the percentage of APP Common Stock currently subject to such Lock-Up
Provisions (as that term is defined below).  By way of example, if the
percentage of APP Common Stock subject to the Lock-Up Provisions is
seventy-five percent (75%) at the time of a Claim Notice or Indemnity Notice,
each Stockholder's Stock Percentage Election may equal, but not exceed,
seventy-five percent (75%) of the amount of the Indemnification Obligation
regardless of the Stock Percentage Elections submitted by the other
Stockholders.  Failure to submit a complete Stock Percentage Election within
the time periods set forth in this Paragraph 2(e) shall be deemed to be an
election for such Stockholder to satisfy such Indemnification Obligation with
100% cash.

                 Each Stockholder's Stock Percentage Election shall be an
irrevocable election as to such Stockholder of the method of payment of the
applicable Indemnification Obligation, and such percentage election between APP
Common Stock and cash shall remain constant with respect to the final payment
of the Indemnification Obligation.  Following each Stockholder's Stock
Percentage Election, each Stockholder shall, in APP's sole discretion, either
(i) transfer the Reserved APP Stock (as that term is defined below) to an
escrow account (the "Escrow Account") established by APP or (ii) consent to a
stop transfer of such APP Common Stock by APP to be either (x) held in the
Escrow Account or (y) subject to such stop order, as the case may be, until
final payment of the Indemnification Obligation as set forth in Paragraph
2(e)(4).

                 The remaining portion of the Indemnification Obligation not
satisfied by the Stock Percentage Election shall be valued in cash, however,
the cash portion shall not be transferred to the Escrow Account.  By way of
example, if the Stock Percentage Election is 75%, the remaining 25% of the
Indemnification Obligation shall be paid in cash.

                          (2)     For purposes of this Agreement only and in
order to calculate the actual number of shares of Reserved APP Stock to be held
in the Escrow Account or subject the a stop order, the





                                       4
<PAGE>   5
value of each share of APP Common Stock transferred to the Escrow Account or be
subject to a stop transfer pursuant to the Stock Percentage Election shall be
calculated by averaging the daily closing prices for a share of APP Common
Stock for the twenty (20) consecutive trading days on which such shares are
actually traded on the Nasdaq National Market (or other national securities
exchange or inter-dealer quotation system) preceding the date of the Claim
Notice or Indemnity Notice, as the case may be (the "APP Stock Price").

                          (3)     The number of shares to be reserved by the
transfer to the Escrow Account or subject to a stop transfer to satisfy the
Indemnification Obligation (the "Reserved APP Stock") shall be calculated by
APP according to the following formula:

                                  (i)      Determine the dollar amount of each
Stockholder's proportionate amount of the Indemnification Obligation
("Proportionate Obligation");

                                  (ii)     Multiply the Proportionate
Obligation by the Stock Percentage Election to determine the dollar value of
the Stock Percentage Election ("Stock Election Value"); and

                                  (iii)    Divide the Stock Election Value by
the APP Stock Price to determine the Reserved APP Stock.

Except as set forth herein, the Reserved APP Stock shall remain constant until
the final payment of any Indemnification Obligation.  To determine the amount
of cash required to satisfy the Proportionate Obligation, subtract the Stock
Election Value from the Proportionate Obligation.

                          (4)     On the final payment date pursuant to this
Paragraph 2(e) (the "Actual Payment Date"), the parties hereto will be notified
of the actual dollar amount of the Indemnification Obligation.  On the Actual
Payment Date, if the amount owing by each Stockholder (1) equals the
Proportionate Obligation, then all of the Reserved APP Stock and the cash
portion of the Proportionate Obligation shall be transferred to APP, (2) is
less than the Proportionate Obligation, then the percentage of the Reserved APP
Stock and cash that is required to satisfy the actual Indemnification
Obligation shall be determined by multiplying (a) the total amount of the
actual Indemnification Obligation applicable to each Stockholder divided by the
Proportionate Obligation by the (b) number of shares of Reserved APP Stock for
such Stockholder and (c) the amount of cash that would have been required to
satisfy his or her Proportionate Obligation, or (3) is greater than the amount
of the Proportionate Obligation, then (a) all of the Reserved APP Stock and
cash that would have been required to satisfy his or her Proportionate
Obligation, plus (b) the amount by which the actual Indemnification Obligation
for such Stockholder exceeds the Proportionate Obligation, which additional
amount shall be payable by such Stockholder in cash, shall be transferred to
APP.  By way of example, assume that (i) the amount of the Proportionate
Obligation as of the date of the Claim Notice or Indemnity Notice was equal to
$100,000, (ii) such Stockholder's Stock Election Percentage was 75%, and (iii)
the APP Stock Price was $15.00.  The number of shares required to be placed
into the Escrow Account or subject to a stop transfer by such Stockholder would
be 5,000 shares of APP Common Stock ($100,000 X 75%/$15.00).  If the actual
Indemnification Obligation was (1) $100,000, then all of the Reserved APP
Stock, regardless of the then-current trading price of the APP Common Stock,
plus $25,000 cash would be required to be transferred to APP, (2) $50,000,
which is 50% of the Proportionate Obligation, then 50% of the Reserved APP
Stock held in the Escrow Account or subject to a stop transfer (5,000 shares X
50%), or 2,500 shares, regardless of the then-current trading price of APP
Common Stock, plus $12,500 cash would be required to be transferred to APP, or
(3) $150,000, then all of the Reserved APP Stock held in the Escrow Account or
subject to a stop transfer, regardless of the then-current trading price of APP
Common Stock, $25,000 cash, plus an





                                       5
<PAGE>   6
additional $50,000 cash (the difference between the actual Indemnification
Obligation and the Proportionate Obligation) would be required to be
transferred to APP.

All payments of cash in satisfaction of the actual Indemnification Obligation
pursuant to this Indemnification Agreement shall be made to APP by cashier's
check.

                          (5)     Notwithstanding any provision contained
herein to the contrary, (1) each Stockholder shall be entitled to transfer to
APP shares of APP Common Stock held by such Stockholder which are subject to
the Lock-Up Provisions contained in Paragraph 1 of the Stockholder
Representation Letter ("Lock-Up Provisions") and (2) the provisions of
Paragraphs 2(e)(1) through (5) shall have no further force or effect, and shall
not apply in any manner whatsoever, with respect to any Claim Notice or
Indemnity Notice which is given subsequent to the earlier of (x) the
termination of the Lock-Up Provisions or (y) the end of the two (2) year period
following the Effective Date.

                 f.       The Indemnifying Parties shall provide the
Indemnified Party with written notice of any firm offer that is made to settle
or compromise a Third Party Claim against an Indemnified Party.  If a firm
offer is made to settle such a claim solely by the payment of money damages and
the Indemnifying Parties notify the Indemnified Party in writing that the
Indemnifying Parties agree to such settlement, but the Indemnified Party elects
not to accept and agree to it, the Indemnified Party may continue to contest or
defend such Third Party Claim and, in such event, the total maximum liability
of the Indemnifying Parties to indemnify or otherwise reimburse the Indemnified
Party hereunder with respect to such a claim shall be limited to and shall not
exceed the amount of such settlement offer, plus reasonable out-of-pocket costs
and reasonable expenses (including reasonable attorneys' fees and
disbursements) to the date of notice that the Indemnifying Parties desired to
accept such settlement.

                 g.       Notwithstanding anything contained in this Agreement
or the Merger Agreement to the contrary, the Indemnifying Parties in the
aggregate (i) shall have no obligation hereunder to provide indemnification for
the first $100,000 of Damages (without counting Immaterial Claims as defined
below), and (ii) in no event shall the Indemnifying Parties have any liability
hereunder with respect to any singular incident or a fact involving a breach or
inaccuracy of the Company if the Damages from such claim are equal to or less
than $7,500 ("Immaterial Claims").  Notwithstanding anything to the contrary
contained herein or in the Merger Agreement, the obligations of each
Stockholder hereunder shall not exceed fifty percent (50%) of the aggregate
value of the Merger Consideration or Exchange Consideration, as the case may
be, paid to such Stockholder pursuant to any Related Acquisition on the Closing
Date.

         3.      Intentionally Omitted.

         4.      Remedies Exclusive.  The remedies provided in this Agreement
are the exclusive rights or remedies available to one party against the other
arising out of or with respect to the Merger Agreement, either at law or in
equity, except in the case of fraud.

         5.      Costs, Expenses and Legal Fees.  Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         6.      Tax Benefits; Insurance Proceeds.  The total amount of any
indemnity payments owed by one party to another party to this Agreement shall
be reduced by any correlative tax benefit received by





                                       6
<PAGE>   7
the party to be indemnified or the net proceeds received by the party to be
indemnified with respect to recovery from third parties or insurance proceeds,
and such correlative insurance benefit shall be net of the insurance premium,
if any, that becomes due as a result of such claim.

         7.      Dispute Resolution.

                 a.       Arbitration.  The parties hereto agree that any
claim, controversy, dispute or disagreement between or among any of the parties
arising out of or relating to this Agreement shall be governed exclusively by
the terms and provisions of this Paragraph 7; provided, however, that within
ten (10) days from the date any party gives notice to the others of its desire
to seek arbitration as provided in Paragraph 7(b) and prior to commencing an
arbitration procedure pursuant to this Paragraph 7, the parties shall meet to
discuss and consider alternative dispute resolution procedures other than
arbitration including, but not limited to Judicial Arbitration & Mediation
Services, Inc., if applicable.  If at any time prior to the rendering of the
decision by the arbitrator (or pursuant to such other alternative dispute
resolution procedure) as contemplated in this Paragraph 7 to the extent a party
makes a written offer to an opposing party proposing a settlement of the
matter(s) at issue and such offer is rejected, then the party rejecting such
offer shall be obligated to pay the costs and expenses (excluding the amount of
the award granted under the decision) of the party that offered the settlement
from the date such offer was received by such other party if the decision is
for a dollar amount that is less than the amount of such offer to settle.
Notwithstanding the foregoing, the terms and provisions of this Paragraph 7
shall not preclude any party hereto from seeking, or a court of competent
jurisdiction from granting, a temporary restraining order, temporary injunction
or other equitable relief for any breach of (i) any noncompetition or
confidentiality covenant or (ii) any duty, obligation, covenant, representation
or warranty, the breach of which may cause irreparable harm or damage.

                 b.       Arbitrators.  In the event there is a claim,
controversy, dispute or disagreement among the parties hereto arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select, within 30 days of
notice by a party to the other of its desire to seek arbitration under this
Paragraph 7 one (1) arbitrator mutually acceptable to the Company and the
Stockholders to hear and decide all such claims under this Paragraph 7.  Each
of the arbitrators proposed shall be impartial and independent of all parties.
If the parties cannot agree on the selection of an arbitrator within said
30-day period, then any party may in writing request the judge of the United
States District Court for the _____________ District of __________ senior in
term of service to appoint the arbitrator and, subject to this Paragraph 7,
such arbitrator shall hear all arbitration matters arising under this Paragraph
7.

                 c.       Applicable Rules.

                          (1)     Each arbitration hearing shall be held at a
place in _____________ acceptable to the arbitrator.  The arbitration shall be
conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof; provided, however, that if the parties hereto agree to an alternative
to arbitration they may agree to an alternative set of rules, including as to
rules of evidence and procedure.  The decision of the arbitrator shall be
reduced to writing and shall be binding on the parties and such decision shall
contain a concise statement of the reasons in support of such decision.
Judgment upon the award(s) rendered by the arbitrator may be entered and
execution had in any court of competent jurisdiction or application may be made
to such court for a judicial acceptance of the award and an order of
enforcement.  The charges and expenses of the arbitrator shall be shared
equally by the parties to the hearing.

                          (2)     The arbitration shall commence within ten
(10) days after the arbitrator is selected in accordance with the provisions of
this Paragraph 7.  In fulfilling his duties with respect to determining the
amount of any loss, the arbitrator may consider such matters as, in the opinion
of the arbitrator, are necessary or helpful to make a proper valuation.  The
arbitrator may consult with and engage disinterested third parties to advise
the arbitrator.  The arbitrator shall not add any interest factor reflecting
the time value of money to the amount of any loss and shall not award any
punitive damages.

                          (3)     If the arbitrator selected hereunder should
die, resign or be unable to perform his or her duties hereunder, the parties,
or such senior judge (or such judge's successor) in the event the parties
cannot agree, shall select a replacement arbitrator.  The procedure set forth
in this Paragraph 7 for selecting the arbitrator shall be followed from time to
time as necessary.

                          (4)     As to any determination of the amount of any
loss, or as to the resolution of any other claim, controversy, dispute or
disagreement, that under the terms hereof is made subject to arbitration, no
lawsuit based on such claimed loss or such resolution shall be instituted by
the parties hereto, other than to compel arbitration proceedings or enforce the
award of the arbitrator, except as otherwise provided in Paragraph 7.

                          (5)     All privileges under [state] and federal law,
including attorney-client and work-product privileges, shall be preserved and
protected to the same extent that such privileges would be protected in a
federal court proceeding applying [state] law.

         8.      Miscellaneous.

                 a.       Amendment; Waivers.  This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto.  Any waiver of any terms and conditions hereof must be in
writing, and signed by the party or parties making any such waiver.  The waiver
of any of the terms and conditions of this Agreement shall not be construed as
a waiver of any other terms and conditions hereof.

                 b.       Assignment.  Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any party hereto.

                 c.       Parties in Interest.  Except as otherwise provided
herein, the terms and conditions of this Agreement shall inure to the benefit
of and be binding upon the respective heirs, legal representatives, successors
and assigns of the parties hereto.

                 d.       Entire Agreement.  This Agreement, the Merger
Agreement and any agreements contemplated hereby constitute the entire
agreement of the parties regarding the subject matter hereof, and supersede all
prior agreements and understandings, both written and oral, among the parties,
or any of them, with respect to the subject matter hereof.

                 e.       Severability.  If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added





                                       8
<PAGE>   9
automatically as part of this Agreement a provision as similar in its terms to
such illegal, invalid or unenforceable provision as may be possible and be
legal, valid and enforceable.

                 f.       Governing Law.  THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF ______________.

                       AMERICAN PHYSICIAN PARTNERS, INC.
                         REGISTRATION RIGHTS AGREEMENT


         THIS REGISTRATION RIGHTS AGREEMENT is made as of the 1~, 1996, by and
between American Physician Partners, Inc., a Delaware corporation (the
"Company"), and each other person or entity executing this Agreement.

                                    RECITALS

         WHEREAS, certain investors (the "Investors") have purchased
Convertible Promissory Notes of the Company (the "Notes")  in connection with
the sale by the Company and the purchase by the Investors of Notes in a private
placement thereof by the Company (the "Private Placement");

         WHEREAS, the Company and the Investors desire to provide for certain
arrangements with respect to the registration of shares of Common Stock of the
Company, issued upon conversion of the Notes  held by the Investors as provided
in this Agreement:

         NOW, THEREFORE, in consideration of the mutual promises and agreements
contained herein and for other good and valuable consideration the receipt and
sufficiency of which are hereby acknowledged, the Company and the Investors
hereby agree as follows:

1.  Registration Rights.   The Company covenants and agrees as follows:

    1.1  Definitions.  For purposes of this Paragraph 1:

        (a)  The term "register", and "registered", and "registration" refer to
        a registration effected by preparing and filing a registration
        statement or similar document in compliance with the Securities Act of
        1933, as amended (the "Securities Act")and the declaration or ordering
        of effectiveness of such registration  statement or document;

        (b)  The term  "Registrable Securities" means (1) the shares of Common
        Stock issued or issuable upon conversion of the shares of Notes and (2)
        any Common Stock of the Company issued as (or issuable upon the
        conversion or exercise of any warrant, right or other security which is
        issued as) a dividend or other distribution with respect to, or in
        exchange for or in replacement of, such Notes or Common Stock,
        excluding in all cases, however, any Registrable Securities sold by a
        person in a transaction in which his rights under this Section 1 are
        not assigned or pursuant to an effective registration statement or to
        the public pursuant to an exemption from registration requirements
        under the Securities Act;

        (c)  The number of shares of "Registrable Securities then outstanding"
        shall be determined by the number of shares of Common Stock outstanding
        which are Registrable Securities, and the number of shares of Common
        Stock issuable pursuant to conversion of all outstanding Notes.

        (d)  The term "Holder" means any person owning or having the right to
        acquire Registrable Securities or any assignee thereof in accordance
        with Section 1.13 hereof; and

        (e)  The term "Form S-3" means such form under the Securities Act as in
        effect on the date hereof or any registration form under the Securities
        Act subsequently adopted by the Securities and Exchange Commission
        ("SEC") which permits inclusion or incorporation of substantial
        information by reference to other documents filed by the Company with
        the SEC.





                                       1

    1.2 Request for Registration.

        (a)  If the Company shall receive at any time one year or more after
        the effective date of the Company's first underwritten public offering
        of shares of Common Stock pursuant to a registration statement in which
        the aggregate gross proceeds to the Company equal or exceeds
        $10,000,000 (the "Initial Public Offering") and prior to September 30,
        2001, a written request from the Holders of more than fifty percent
        (50%) of the Registrable Securities then outstanding that the Company
        file a registration statement under the Securities Act covering the
        registration of at least fifty percent (50%) of the Registrable
        Securities then outstanding, then the Company shall promptly give
        written notice of such request to all Holders and shall, subject to the
        limitations of subsection 1.2 (b), effect as soon as practicable the
        registration under the Securities Act of all Registrable Securities
        which the Holders request to be registered within thirty (30) days of
        the mailing of such notice by the Company in accordance with Section
        2.5.

        (b)  If the Holders initiating the registration request hereunder
        ("Initiating Holders") intend to distribute the Registrable Securities
        covered by their request by means of an underwriting, they shall so
        advise the Company as a part of their request made pursuant to this
        Section 1.2 and the Company shall include such information in the
        written notice referred to in subsection 1.2(a).  The underwriter will
        be selected by a majority in interest of the Initiating Holders and
        approved by the Company, which approval shall not unreasonably be
        withheld.  In such event, the right of any Holder to include his
        Registrable Securities in such registration shall be conditioned upon
        such Holder's participation in such underwriting (unless otherwise
        mutually agreed by a majority in interest of the Initiating Holders and
        such Holder) to the extent provided herein.  All Holders proposing to
        distribute their securities through such underwriting shall (together
        with the Company as provided in subsection 1.4(e)) enter into an
        underwriting agreement in customary form with the underwriter or
        underwriters selected for such underwriting by a majority in interest
        of the Initiating Holders.  Notwithstanding any other provision of this
        Section 1.2, if the underwriter advises the Initiating Holders in
        writing that marketing factors require a limitation of the number of
        shares to be underwritten, then the Initiating Holder shall so advise
        all Holders of Registrable Securities that may be included in the
        underwriting that such number of Registrable Securities to be included
        shall be allocated among all such Holders thereof, including the
        Initiating Holders, in proportion (as nearly as practicable) to the
        amount of Registrable Securities of the Company owned by each Holder;
        provided, however, that the number of shares of Registrable Securities
        to be included in such underwriting shall not be reduced unless all
        other securities are first entirely excluded from the underwriting.

        (c)  The Company is obligated to effect only one (1) such registration
        pursuant to this Section 1.2.

        (d)  Notwithstanding the foregoing, if the Company shall furnish to
        Holders requesting a registration statement pursuant to this Section
        1.2 a certificate signed by the President of the Company stating that
        in the good faith judgment of the Board of Directors of the Company it
        would be seriously detrimental to the Company and its shareholders for
        such registration statement to be filed and it is therefore essential
        to defer the filing of such registration statement, the Company shall
        have the right to defer taking any action with respect to such filing
        for a period of not more than 90 days after receipt of the request of
        the Initiating Holders; provided, however, that the Company may not
        utilize this right more than once in any twelve month period.

    1.3 Company Registration.

        (a)  If (but without any obligation to do so) at any time one year or
        more after the Initial Public Offering and prior to September 30, 2001,
        the Company proposes to register (including for this purpose a
        registration effected by the Company for shareholders other than the
        Holders) any of its stock or other securities under the Securities Act
        in connection with the public offering of such securities solely for
        cash (other than a registration relating solely to the sale of
        securities to participants in a Company stock plan, a registration
        statement relating to a merger, a registration statement on Form S-4 or
        a registration on any





                                       2
<PAGE>   3

        form which does not include substantially the same information as would
        be required to be included in a registration statement covering the
        sale of the Registrable Securities), the Company shall, at such time,
        promptly give each Holder written notice of such registration.  Upon
        the written request of each Holder given within thirty (30) days after
        mailing of such notice by the Company in accordance with Section 2.5,
        the Company shall, subject to the provisions of Section 1.8, cause to
        be registered under the Securities Act all of the Registrable
        Securities that each such Holder has requested to be registered.

        (b)  The Company's obligations pursuant to subsection 1.3(a) above
        shall apply only to the first  two (2) Company Registrations described
        in subsection 1.3(a).

    1.4 Obligations of the Company.  Whenever required under this Paragraph 1
    to effect the registration of any Registrable Securities, the Company
    shall, as expeditiously as reasonably possible:

        (a)  Prepare and file with the SEC a registration statement with
        respect to such Registrable Securities and use its best efforts to
        cause such registration statement to become effective and, upon the
        request of the Holders of a majority of the Registrable Securities
        registered thereunder, keep such registration statement effective for
        up to one hundred twenty (120) days for the purpose of selling all
        stock or securities registered with the SEC.

        (b)  Prepare and file with the SEC such amendments and supplements to
        such registration statement and the prospectus used in connection with
        such registration statement as may be necessary to comply with the
        provisions of the Securities Act with respect to the disposition of all
        securities covered by such registration statement.

        (c)  Furnish to the Holders such numbers of copies of a prospectus,
        including a preliminary prospectus, in conformity with the requirements
        of the Securities Act, and such other documents as they may reasonably
        request in order to facilitate the disposition of Registrable
        Securities owned by them.

        (d)  Use its best efforts to register and qualify the securities
        covered by such registration statement under such other securities or
        Blue Sky laws of such jurisdictions as shall be reasonably requested by
        the Holders, provided that the Company shall not be required in
        connection therewith or as a condition thereto to qualify to do
        business or to file a general consent to service of process in any such
        states or jurisdictions.

        (e)  In the event of any underwritten public offering, enter into and
        perform its obligations under an underwriting agreement, in usual and
        customary form, with the managing underwriter or such offering.  Each
        Holder participating in such underwriting shall also enter into and
        perform its obligations under such an agreement.

        (f)  Notify each Holder of Registrable Securities covered by such
        registration statement at any time when a prospectus relating thereto
        is required to be delivered under the Securities Act of the happening
        of any event as a result of which the prospectus included in such
        registration statement, as then in effect, includes an untrue statement
        of a material fact or omits to state a material fact required to be
        stated therein or necessary to make the statements therein not
        misleading in the light of the circumstances then existing.

        (g)  Furnish, at the request of any Holder requesting registration of
        Registrable Securities pursuant to this Paragraph 1, on the date that
        such Registrable Securities are delivered to the underwriters for sale
        in connection with a registration pursuant to this Paragraph 1 if such
        securities are being sold through underwriters, or, if such securities
        are not being sold through underwriters on the date that the
        registration statement with respect to such securities becomes
        effective, (i) an opinion dated such date of the counsel representing
        the Company for the purposes of such registration, in form and
        substance as is customarily given to underwriters in an underwritten
        public offering, addressed to the underwriters, if any, and to the
        Holders requesting registration of Registrable Securities and (ii)  a
        "cold comfort" letter dated such date





                                       3
<PAGE>   4

        from the independent certified public accountants of the Company, in
        form and substance as is customarily given by independent certified
        public accountants to underwriters in an underwritten public offering,
        addressed to the underwriters, if any, and to the Holders requesting
        registration of Registrable Securities.

    1.5 Furnish Information.

        (a)  It shall be a condition precedent to the obligations of the
        Company to take any action pursuant to this Section 1 with respect to
        the Registrable Securities of any selling Holder that such Holder shall
        furnish to the Company such information regarding itself, the
        Registrable Securities held by it, and the intended method of
        disposition of such securities as shall be required to effect the
        registration of such Holder's Registrable Securities.

        (b)  The Company shall have no obligation with respect to any
        registration requested pursuant to Section 1.2 or Section 1.12 if, due
        to the operation of subsection 1.5(a), the number of shares or the
        anticipated aggregate offering price of the Registrable Securities to
        be included in the registration does not equal or exceed the number of
        shares or the anticipated aggregate offering price required to
        originally trigger the Company's obligation to initiate such
        registration as specified in subsection 1.2(a) or subsection
        1.12(b)(2), whichever is applicable.

    1.6 Expenses of Demand Registration.  All expenses other than underwriting
    discounts and commissions incurred in connection with registrations,
    filings, or qualifications pursuant to Section 1.2, including without
    limitation all registration, filing and qualification fees, printers' and
    accounting fees, fees and disbursements of counsel for the Company, and the
    reasonable fees and disbursements of one counsel for the selling Holders
    shall be borne by the Company; provided, however, that the Company shall
    not be required to pay for any expenses of any registration proceeding
    begun pursuant to Section 1.2 if the registration request is subsequently
    withdrawn at the request of the Holders of a majority of the Registrable
    Securities to be registered (in which case all Participating Holders shall
    bear such expenses), unless the Holders of a majority of the Registrable
    Securities agree to forfeit their right to demand registration pursuant to
    Section 1.2; provided further, however, that if at the time of such
    withdrawal, the Holders have learned of a material adverse change in the
    condition, business, or prospects of the Company from that known to the
    Holders at the time of their request and have withdrawn the request with
    reasonable promptness following disclosure by the Company of such material
    adverse change, then the Holders shall not be required to pay any of such
    expenses and shall retain their rights pursuant to Section 1.2.  Fees and
    disbursements of counsel and accountants for the selling Holders and any
    other expenses incurred by the selling Holders not expressly included above
    shall be borne by the selling Holders.

    1.7 Expenses of Company Registration.  The Company shall bear and pay all
    expenses incurred in connection with any registration, filing or
    qualification of Registrable Securities with respect to all registrations
    pursuant to Section 1.3 for each Holder (which right may be assigned as
    provided in Section 1.13), including without limitation all registration,
    filing, and qualification fees, printers and accounting fees relating or
    apportionable thereto and the fees and disbursements of one counsel for the
    selling Holders selected by them, but excluding underwriting discounts and
    commissions relating to Registrable Securities.

    1.8 Underwriting Requirements.  In connection with any offering involving
    an underwriting of shares of the Company's capital stock, the Company shall
    not be required under Section 1.3 to include any of the Holders' securities
    in such underwriting unless they accept the terms of the underwriting as
    agreed upon between the Company and the underwriters selected by it (or by
    other persons entitled to select the underwriters), and then only in such
    quantity as the underwriters determine in their sole discretion will not
    jeopardize the success of the offering by the Company.  If the total amount
    of securities, including Registrable Securities, requested by shareholders
    to be included in such offering exceeds the amount of securities sold other
    than by the Company that the underwriters determine in their sole
    discretion is compatible with the success of the offering, then the Company
    shall be required to include in the offering only that number of such
    securities, including Registrable





                                       4
<PAGE>   5
    Securities, which the underwriters determine in their sole discretion will
    not jeopardize the success of the offering (the securities so included to
    be apportioned pro rata among the selling shareholders according to the
    total amount of securities entitled to be included therein owned by each
    selling shareholder or in such other proportions as shall mutually be
    agreed to by such selling shareholders) but in no event shall (i) the
    amount of securities, including Registrable Securities and all other
    securities the holders of which have similar rights, of the selling
    shareholders included in the offering be reduced below thirty percent (30%)
    of the total amount of securities included in such offering, or (ii)
    notwithstanding (i) above, any shares being sold by a shareholder
    exercising a demand registration right similar to that granted in Section
    1.2 be excluded from such offering.  For purposes of the preceding
    parenthetical concerning apportionment of any selling shareholder which is
    a holder of Registrable Securities and which is a partnership or
    corporation, the partners, retired partners and shareholders of such
    holder, or the estates and family members of any such partners and retired
    partners and any trusts for the benefit of any of the foregoing persons
    shall be deemed to be a single "selling shareholder", and any pro-rata
    reduction with respect to such "selling shareholder" shall be based upon
    the aggregate amount of shares carrying registration rights owned by all
    entities and individuals included in such "selling shareholder", as defined
    in this sentence.

    1.9 Delay of Registration.  No Holder shall have any right to obtain or
    seek any injunction restraining or otherwise delaying any such registration
    as a result of any controversy that might arise with respect to the
    interpretation or implementation of this Paragraph 1.

    1.10  Indemnification.  In the event any Registrable Securities are
    included in a registration statement under this Paragraph 1:

        (a)  To the extent permitted by law, the Company will indemnify and
        hold harmless each Holder, any underwriter (as defined in the
        Securities Act) for such Holder and each person, if any, who controls
        such Holder or underwriter within the meaning of the Securities Act or
        the Securities and Exchange Act of 1934, as amended (the "1934 Act"),
        against any losses, claims, damages, or liabilities (joint or several)
        to which they may become subject under the Securities Act, or the 1934
        Act or other federal or state law, insofar as such losses, claims,
        damages, or liabilities (or actions in respect thereof) arise out of or
        are based upon any of the following statements, omissions or violations
        (collectively a "Violation:):  (i) any untrue statement or alleged
        untrue statement of a material fact contained in such registration
        statement, including any preliminary prospectus or final prospectus
        contained therein or any amendments or supplements thereto, (ii) the
        omission or alleged omission to state therein a material fact required
        to be stated therein, or necessary to make the statements therein not
        misleading, or (iii) any violation or alleged violation by the Company
        of the Securities Act, the 1934 Act, any state securities law or any
        rule or regulation promulgated under the Securities Act, or the 1934
        Act or any state securities law; and the Company will pay to each such
        Holder, underwriter or controlling person, as incurred, any legal or
        other expenses reasonably incurred by them in connection with
        investigating or defending any such loss, claim, damage, liability or
        action; provided, however, that the indemnity agreement contained in
        this subsection 1.10(a) shall not apply to amounts paid in settlement
        of any such loss, claim, damage, liability, or action if such
        settlement is effected without the consent of the Company (which
        consent shall not be unreasonably withheld), nor shall the Company be
        liable in any such case for any such loss, claim, damage, liability, or
        action to the extent that it arises out of or is based upon a Violation
        which occurs in reliance upon and in conformity with written
        information furnished expressly for use in connection with such
        registration by any such Holder, underwriter or controlling person.

        (b)  To the extent permitted by law, each selling Holder will indemnify
        and hold harmless the Company, each of its directors, each of its
        officers who has signed the registration statement, each person, if
        any, who controls the Company within the meaning of the Securities Act,
        any underwriter, any other Holder selling securities in such
        registration statement and any controlling person of any such
        underwriter or other Holder, against any losses, claims, damages, or
        liabilities (joint or several) to which any of the foregoing persons
        may become subject, under the Securities Act, or the 1934 Act or other
        federal or state law, insofar as such





                                       5
<PAGE>   6
        losses, claims, damages, or liabilities (or actions in respect thereto)
        arise out of or are based upon and in conformity with written
        information furnished by such Holder expressly for use in connection
        with such registration; and each such Holder will pay, as incurred, any
        legal or other expenses reasonably incurred by any person intended to
        be indemnified pursuant to this subsection 1.10(b), in connection with
        investigating or defending any such loss, claim, damage, liability, or
        action; provided, however, that the indemnity agreement contained in
        this subsection 1.10(b) shall not apply to amounts paid in settlement
        of any such loss, claim, damage, liability or action if such settlement
        is effected without the consent of the Holder, which consent shall not
        be unreasonably withheld; provided that in no event shall any indemnity
        under this subsection 1.10(b) exceed the gross proceeds from the
        offering received by such Holder.

        (c)  Promptly after receipt by an indemnified party under this Section
        1.10 of notice of the commencement of any action (including any
        governmental action), such indemnified party will, if a claim in
        respect thereof is to be made against any indemnifying party under this
        Section 1.10, deliver to the indemnifying party a written notice of the
        commencement thereof and the indemnifying party shall have the right to
        participate in, and, to the extent the indemnifying party so desires,
        jointly with any other indemnifying party similarly noticed, assume the
        defense thereof with counsel mutually satisfactory to the parties;
        provided, however, that an indemnified party (together with all other
        indemnified parties which may be represented without conflict by one
        counsel) shall have the right to retain one separate counsel, with the
        fees and expenses to be paid by the indemnifying party, if
        representation of such indemnified party by the counsel retained by the
        indemnifying party would be inappropriate due to actual or potential
        differing interests between such indemnified proceeding.  The failure
        to deliver written notice to the indemnifying party within a reasonable
        time of the commencement of any such action, if prejudicial to its
        ability to defend such action, shall relieve such indemnifying party of
        any liability to the indemnified party under this Section 1.10, but the
        omission to deliver written notice to the indemnifying party will not
        relieve it of any liability that it may have to any indemnified party
        otherwise than under this Section 1.10.

        (d)  If the indemnification provided for in this Section 1.10 is held
        by a court of competent jurisdiction to be unavailable to an
        indemnified party with respect to any loss, liability, claim, damage,
        or expenses referred to therein, then the indemnifying party, in lieu
        of indemnifying such indemnified party hereunder, shall contribute to
        the amount paid or payable by such indemnified party as a result of
        such loss, liability, claim, damage, or expense in such proportion as
        it appropriate to reflect the relative fault of the indemnifying party
        on the one hand and of the indemnified party on the other in connection
        with the statements or omissions that resulted in such loss, liability,
        claim, damage, or expense as well as any other relevant equitable
        considerations.  The relative fault of the indemnifying party and of
        the indemnified party shall be determined by reference to, among other
        things, whether the untrue or alleged untrue statement of a material
        fact or the omission to state a material fact relates to information
        supplied by the indemnifying party or by the indemnified party and the
        parties' relative intent, knowledge, access to information, and
        opportunity to correct or prevent such statement or omission.

        (e)  Notwithstanding the foregoing, to the extent that the provisions
        on indemnification and contribution contained in the underwriting
        agreement entered into in connection with the underwritten public
        offering are in conflict with the foregoing provisions, the provisions
        in the underwriting agreement shall control.

        (f)  The obligations of the Company and Holders under this Section 1.10
        shall survive the completion of any offering of Registrable Securities
        in a registration statement under this Paragraph 1, and otherwise.

    1.11 Reports Under Securities Exchange Act of 1934.  With a view to making
    available to the Holders the benefits of Rule 144 promulgated under the Act
    and any other rule or regulation of the SEC that may at any time permit a
    Holder to sell securities of the Company to the public without registration
    or pursuant to a registration on Form S-3, the Company agrees to:

        (a)  make and keep public information available, as those terms are
        understood and defined in SEC Rule





                                       6
<PAGE>   7
        144, at all times after ninety (90) days after the effective date of
        the Initial Public Offering filed by the Company for the offering of
        its securities to the general public;

        (b)  take such action as is necessary to enable the Holders to utilize
        Form S-3 for the sale of their Registrable Securities;

        (c)  file with the SEC in a timely manner all reports and other
        documents required of the Company under the Securities Act and 1934
        Act; and

        (d)  furnish to any Holder, so long as the Holder owns any Registrable
        Securities, forthwith upon request (i) a written statement by the
        Company that it has complied with the reporting requirements of SEC
        Rule 144 (at any time after ninety (90) days following the effective
        date of the Initial Public Offering), the Securities Act and the 1934
        Act (at any time after it has become subject to such reporting
        requirements), or that it qualifies as a registrant who securities may
        be resold pursuant to Form S-3 (at any time after it so qualifies),
        (ii) a copy of the most recent annual or quarterly report of the
        Company and such other reports and documents so filed by the Company,
        and (iii) such other information as may be reasonably requested in
        availing any Holder of any rule or regulation of the SEC which permits
        the selling of any such securities without registration or pursuant to
        such form.

    1.12 Form S-3 Registration.  In case the Company shall receive from any
    Holder or Holders a written request or requests that the Company effect a
    registration on Form S-3 and any related qualification or compliance with
    respect to all or a part of the Registrable Securities owned by such Holder
    or Holders, the Company will:

        (a)  promptly give written notice of the proposed registration, and any
        related qualification or compliance, to all other Holders; and

        (b)  as soon as practicable, effect such registration and all such
        qualifications and compliances as may be so requested and as would
        permit or facilitate the sale and distribution of all or such portion
        of such Holder's or Holders' Registrable Securities as are specified in
        such request, together with all or such portion of the Registrable
        Securities of any other Holder or Holders joining in such request as
        are specified in a written request given within 15 days after receipt
        of such written notice from the Company; provided, however, that the
        Company shall not be obligated to effect any such registration,
        qualification, or compliance, pursuant to this Section 1.12: (1) if
        Form S-3 is not available for such offering by the Holders; (2)  if the
        Holders, together with the holders of any other securities of the
        Company entitled to inclusion in such registration, propose to sell
        Registrable Securities and such other securities (if any) at an
        aggregate price to the public (net of any underwriters' discounts or
        commissions) of less than $250,000; (3) if the Company shall furnish to
        the Holders a certificate signed by the President of the Company
        stating that in the good faith judgment of the Board of Directors of
        the Company, it would be seriously detrimental to the Company and its
        shareholders for such Form S-3 registration to be effected at such
        time, in which event the Company shall have the right to defer the
        filing of the Form S-3 registration statement for a period of not more
        than 90 days after receipt of the request of the Holder or Holders
        under this Section 1.12; provided, however, that the Company shall not
        utilize this right more than once in any twelve month period; (4) if
        the Company has, within the twelve (12) month period preceding the date
        of such request, already effected a registration on Form S-3 for the
        Holders pursuant to this Section 1.12; (5) in any particular
        jurisdiction in which the Company would be required to qualify to do
        business or to execute a general consent to service of process in
        effecting such registration, qualification, or compliance; (6) if the
        Company has previously effected two (2) such registrations; or (7) if
        it is to be effected after September 30, 2001.

        (c)  Subject to the foregoing, the Company shall file a registration
        statement covering the Registrable Securities and other securities so
        requested to be registered as soon as practicable after receipt of the
        request or requests of the Holders.  All expenses incurred in
        connection with a registration requested





                                       7
<PAGE>   8
        pursuant to this Section 1.12, including (without limitation) all
        registration, filing, qualification, printing and accounting fees and
        the reasonable fees and disbursements of counsel of the Company shall
        be borne by the Company.  Registrations effected pursuant to this
        Section 1.12 shall not be counted as demands for registration or
        registrations effected pursuant to Section 1.2 or Section 1.3,
        respectively.

    1.13 Assignment of Registration Rights.  The rights to cause the Company to
    register Registrable Securities pursuant to this Paragraph 1 may be
    assigned (but only with all related obligations) by a Holder to a
    transferee or assignee of such securities provided the Company is within a
    reasonable time after such transfer furnished with written notice of the
    name and address of such transferee or assignee and the securities with
    respect to which such registration rights are being assigned; and provided,
    further, that such assignment shall be effective only if immediately
    following such transfer the further disposition of such securities by the
    transferee or assignee is restricted under the Securities Act.

    1.14 Limitation on Subsequent Registration Rights.  From and after the date
    of this Agreement, the Company shall not, without the prior written consent
    of the Holders of a majority of the outstanding Registrable Securities,
    enter into any agreement with any holder or prospective holder of any
    securities of the Company which would allow such holder or prospective
    holder (a) to include such securities in any registration filed under
    Section 1.2 hereof, unless under the terms of such agreement, such holder
    or prospective holder may include such securities in any such registration
    only to the extent that the inclusion of his securities will not reduce the
    amount of the Registrable Securities of the Holders which is included or
    (b) to make a demand registration which could result in such registration
    statement being declared effective prior to the first anniversary of the
    effective date of the Initial Public Offering.

    1.15 "Market Stand-Off" Agreement.  Each Investor hereby agrees that,
    during the period of duration specified by the Company and an underwriter
    of common stock or other securities of the Company, following the effective
    date of a registration statement of the Company filed under the Securities
    Act, it shall not, to the extent requested by the Company and such
    underwriter, directly or indirectly sell, offer to sell, contract to sell
    (including, without limitation, any short sale), grant any option to
    purchase or otherwise transfer or dispose of (other than to donees who
    agree to be similarly bound) any securities of the Company held by it at
    any time during such period except common stock included in such
    registration; provided however, that:

        (a)  such agreement shall be applicable only to the first such
        registration statement of the Company which covers common stock (or
        other securities) to be sold on its behalf to the public in an
        underwritten offering; and

        (b)  all officers and directors of the Company and all other persons
        with registration rights (whether or not pursuant to this Agreement)
        enter into similar agreements.

        In order to enforce the foregoing covenant, the Company may impose
        stop-transfer instructions with respect to the Registrable Securities
        of each Investor (and the shares or securities of every other person
        subject to the foregoing restriction) until the end of such period.

    1.16 Termination of Registration Rights.  No Holder shall be entitled to
    exercise any right provided for in this Section 1 after September 30, 2001.

2. Miscellaneous.

    2.1 Successors and Assigns.  Except as otherwise provided herein, the terms
    and conditions of this Agreement shall inure to the benefit of and be
    binding upon the respective successors and assigns of the parties
    (including transferees of the Notes or the Registrable Securities).
    Nothing in this Agreement, express or implied, is intended to confer upon
    any party other than the parties hereto or their respective successors and
    assigns any rights, remedies, obligations, or liabilities under or by
    reason of this Agreement, except as expressly provided





                                       8
<PAGE>   9

    in this Agreement.

    2.2 Governing Law.  This Agreement shall be governed by and construed under
    the laws of the State of Delaware without giving effect to principles of
    conflicts of laws.

    2.3 Counterparts.  This Agreement may be executed in two or more
    counterparts, each of which shall be deemed an original, but all of which
    together shall constitute one and the same instrument.

    2.4 Titles and Subtitles.  The titles and subtitles used in this Agreement
    are used for convenience only and are not to be considered in construing or
    interpreting this Agreement.

    holders of Common Stock of the Company on the date hereof (the "Common
    Holders") by a written instrument executed by the Company and each Common
    Holder electing to be included as a party hereto.  Any amendment or waiver
    effected in accordance with this Section 2.7 shall be binding upon each
    holder of any Registrable Securities then outstanding, each future holder
    of all such Registrable Securities, and the Company.

    2.7 Severability.  If one or more provisions of this Agreement are held to
    be unenforceable under applicable law, such provision shall be excluded
    from this Agreement and the balance of the Agreement shall be interpreted
    as if such provision were so excluded and shall be enforceable in

                                   ARTICLE III

                    Services to be Provided by Administrator

         Section 3.1 General.

         (a) Scope of Services Provided. Administrator shall provide or arrange
for the services set forth in this Article III, and the costs, fees, expenses
and other disbursements incurred by Administrator or Parent in connection
therewith shall be included in Practice Expenses, except to the extent such
costs, fees or expenses are expressly included in Excluded Practice Expenses or
Administrator Expenses. Administrator is authorized to perform its services
hereunder as is necessary or appropriate for the efficient operation of the
Practice, including, without limitation, performance of some of the business
office functions at locations other than the Practice. Except to the extent
necessary to comply with applicable laws, regulations or professional ethical
standards, the Group will not act in a manner which would prevent Administrator
from performing its duties hereunder and will provide such information and
assistance to Administrator as is reasonably required by Administrator to
perform its services hereunder. Administrator shall cause its employees, to
comply with all applicable federal, state and local laws, rules and regulations
in Administrator's provision of services hereunder.

         (b) Alternative Management Arrangements.

procedures Administrator, Parent or their Affiliates shall utilize to restore
the level of service contemplated by this Agreement. In the event Administrator
fails to restore the level of service contemplated by this Agreement in
accordance with such plan submitted or in any event within ninety (90) days, the
Group shall be entitled to reimbursement by Administrator for the reasonable
costs and expenses of obtaining such service on a temporary basis until such
time Administrator demonstrates its ability to perform such service at the level
contemplated by this Agreement. Nothing contained in this subsection (b)(i)

Administrator Default pursuant to Section 10.3(b) of this Agreement.

            (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service
is construed or deemed to constitute the practice of medicine, Administrator
shall deliver to the Group notice of such an event. The Group shall be entitled
to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

its exclusive manager and administrator of non-medical business services
relating to the operation of the Practice, subject to matters reserved for the
Group or referred to the Joint Planning Board as herein contemplated, and
Administrator shall have all necessary authority and hereby agrees to perform
such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

         (b) Billing and Collection.

            (i) Administrator shall, in the name of and on behalf of the Group,
bill patients, insurance companies, Managed Care Payors, and other third-party
payors and collect all fees for services rendered in connection with the
Practice at the Premises or any Practice Site(s) (including all fees generated
by both the Technical Operations and the Professional Operations), for services
performed outside the Practice for its hospitalized patients, and for all other
professional and Practice services. The Group hereby appoints Administrator for
the term of this Agreement to be its true and lawful attorney-in-fact, for the
following purposes:


                                       10


<PAGE>   16


                    (A) to bill patients, insurance companies, Managed Care
Payors, and other third-party payors in the Group's name and on its behalf;

                    (B) to collect accounts receivable resulting from such
billing not otherwise purchased by Administrator (as provided for in Section
3.2(e) hereof) in the Group's name and on its behalf;

                    (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                    (D) to ensure the collection and receipt in Administrator's
name and for Administrator's account of all accounts receivable of the Practice
purchased by Administrator, and to deposit such collections in the Account;

                    (E) to take possession of and endorse in the name of the
Group and deposit into the Deposit Account (and/or in the name of an individual
physician, such payment intended for purpose of payment of professional fees
related to the Practice) any notes, checks, money orders, insurance payments and
other instruments received in payment of accounts receivable not otherwise
purchased by Administrator; and

                    (F) upon the prior consent of the Group, which consent shall
not be unreasonably withheld or delayed, to initiate the institution of legal
proceedings in the name of the Group or a Physician Employee to collect any
accounts and monies owed to the Group or the Physician Employee, to enforce the
rights of the Group or the Physician Employee, as the case may be, as creditor
under any contract or in connection with the rendering of any service, and to
contest adjustments and denials by governmental agencies (or their fiscal
intermediaries) as third-party payors.

            (ii) The Group hereby appoints Administrator as its true and lawful
attorney-in-fact to deposit into the Deposit Account all Professional Revenues
and Technical Revenues collected by Administrator as provided for in this
Section 3.2(b). The Group covenants, and shall cause all Physician Employees and
Physician Extender Employees to covenant, to forward any payments received with
respect to any Professional Revenues or Technical Revenues generated for
services provided by the Group or any of its Physician Employees and Physician
Extender Employees to Administrator for deposit. Administrator shall have the
right to withdraw funds from the Deposit Account and all owners of the Deposit
Account shall execute a revocable standing transfer order (the "Transfer Order")
under which the bank maintaining the Deposit Account shall periodically transfer
the entire balance of the Deposit Account to a separate bank account owned
solely by Administrator (the "Administrator Account"). The Group and
Administrator hereby agree to execute from time to time such documents and
instructions as shall be required by the bank maintaining the Deposit Account
and mutually agreed upon to effectuate the foregoing provisions and to extend or
amend such documents and instructions. Any action by the Group that materially
interferes with the operation of this Section, including but not limited 


                                       11


<PAGE>   17

to, any failure to deposit or to have Administrator deposit any Professional
Revenues and/or Technical Revenues into the Deposit Account, any withdrawal of
any funds from the Deposit Account not authorized by the express terms of this
Agreement or any other written agreement executed by each of the parties, or any
revocation of or attempt to revoke the Transfer Order (otherwise than upon
expiration or termination of this Agreement), will constitute a breach of this
Agreement and will entitle Administrator, in addition to any other remedies it
may have at law or in equity, to seek a court ordered assignment of the rights
provided to Administrator pursuant to subparagraph (i) above.

            (iii) All monies shall be accounted for by Administrator as being
distinctly attributable to the Group. The Group may perform the functions or
exercise the rights set forth in this Section 3.2(b) only with the prior written
consent of Administrator. The Group shall execute such documents in form and
substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c) Accounting. Administrator shall administer and maintain the

representatives shall have the right to review all financial books and records
maintained by Administrator relating to the operation of the Practice and to the
cash management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the 


                                       12


<PAGE>   18


parties have agreed herein. The purchase price shall be an amount equal to the
aggregate face amount of the accounts receivable being sold less contractual
adjustments and estimated allowances for bad debt as determined from time to
time based on recent historical collection experience of one year or less.
Administrator shall make appropriate adjustments for bad debt and contractual
allowances following the close of each fiscal quarter of the Administrator.

Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group

later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

expenditures.

             (ii) Non-Budgeted Expenditures. Requests for non-budgeted capital
expenditures and improvement projects shall be evaluated and prepared by the
Joint Planning Board in consultation with the Group and Administrator. All

of Directors of Parent or by any committee specifically designated by the Board
of Directors of Parent for such purposes.

         (c) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance 


                                       17

companies, hospitals and other similar persons (collectively, "Managed Care
Payors"). Approval, disapproval, termination or amendment of any contract or
relationship of such Managed Care Payors with the Group shall, after
consultation with the Joint Planning Board, be the responsibility of the Group.
Notwithstanding the preceding language, if a contract or relationship between
any Managed Care Payor and the Group involves or affects a contract or
relationship with any other physician group or practice serviced or managed by
Administrator, Parent or any of their Affiliates (the "Other Practices") and a
consensus among the Group and the Other Practices cannot be reached regarding
the contract or relationship, then the ultimate decision as to the approval,
disapproval, termination or amendment of such contract or relationship involving
the Group, the Other Practices and such Managed Care Payor shall be determined
by the affirmative vote of the Physician Board Members (as defined below) who
hold a majority of the Group Voting Power (as defined below). For purposes of
this Section 3.7, (i) the term "Physician Board Members" shall mean (a) those
members appointed by the Group who serve on the Joint Planning Board and (b)
those persons appointed by the Other Practices who serve on the Other Practices'
joint boards (in a similar capacity to the Joint Planning Board) as part of
their contractual relationship with Parent, Administrator or any of their
Affiliates, and (ii) the term "Group Voting Power" shall mean the total voting
percentage which may be cast by the Physician Board Members on a collective
basis, with the percentage of votes able to be cast by any Group or Other
Practice, as applicable, shall be equal to the quotient determined by dividing
(x) the total estimated annual professional revenues to be generated by the
Group from such Managed Care Contract as determined by Administrator, Parent or
their Affiliates, as appropriate, in its sole discretion, by (y) the total
estimated annual professional revenues to be generated by the Group and all
Other Practices from such Managed Care Contract as determined by the
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion.

         Section 3.8 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.9 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and 


                                       18


<PAGE>   24


advertising programs shall be conducted in compliance with applicable standards
of medical ethics, laws and regulations.

         Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program
shall be included in Administrator Expenses; provided, however, that any
expenses related to such program that are incurred for services provided solely
for the direct benefit of the Practice shall be included in Practice Expenses.

         Section 3.11 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by
the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

         Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.

                                   ARTICLE IV

                            Obligations of the Group

         Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. 


                                       19

The Group shall cooperate in the obtaining and retaining of professional
liability insurance by ensuring that its Physician Employees and Physician
Extender Employees, and other employees who may have malpractice exposure or
liability, are insurable and by participating in an ongoing risk management
program.

         Section 4.2 Professional Services. The Group shall provide professional
services to its patients in compliance at all times with ethical standards,
laws, rules and regulations applicable to the operations of the Practice, the
Physician Employees and Physician ExtenderEmployees. The Group shall ensure that
each Physician Employee and each Physician Extender Employee has all required
licenses, credentials, approvals or other certifications to perform his or her
duties and services for the Practice and, in the event that the Group becomes
aware of any disciplinary actions or medical malpractice actions initiated
against any Physician Employee or Physician Extender Employee, the Group shall
promptly inform Administrator of such action and the underlying facts and
circumstances. If required by applicable law, any state or federal regulatory
agency or any contractual obligations, the Group shall carry out a program to
monitor the quality of medical care practiced at the Practice; provided,
however, that the preceding language shall not limit the Group's obligation to
participate in or comply with any programs established by Administrator or
Parent for purposes of ensuring that the Group complies with applicable law. The
Group shall employ Physician Employees and Physician Extender Employees as is
necessary to provide efficient medical care to patients of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery
items on prepaid Managed Care Contracts which are authorized and permitted by
such contracts. A copy of such agreements and any amendment thereto shall be
provided to Administrator for review no later than thirty (30) days prior to the
proposed effective date thereof.

to provide, distribution of professional fee income among the Group Physician
Stockholders, disposition of the Group's property and stock (subject to any
restrictions contained herein), hiring and firing of its employees, licensing
and implementing all compliance plans and procedures as described in Section

Agreement the names set forth on Schedule 4.5 as may be necessary or appropriate

comply and shall cause each Physician Employee, Physician Extender Employee and
other employee of the Group to comply, with all laws applicable to the operation
of the Practice in the generation, transportation, treatment, storage, disposal

waste, and the Group shall not, and shall use its best efforts to prohibit any
Physician Employee, Physician Extender Employee and any employee of the Group
from:

         (a) entering into any contract, lease, agreement or arrangement,

                                    ARTICLE V

                              Joint Planning Board

         Section 5.1 Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy 


                                       23


<PAGE>   29


is counted; provided, however, that no proxy shall be valid after the expiration
of eleven (11) months from the date of the proxy, unless otherwise provided in
the proxy.

         Section 5.2 Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

         (a) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess
of five percent (5%) to the annual capital or operating budgets.

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

         (d) Patient Fees. As a part of the annual operating budget, in

shall review and adopt the fee schedule for all professional services rendered
by the Practice.

         (e) Ancillary Services and Fees. The Joint Planning Board shall approve
Practice-provided non-medical ancillary services (including, without limitation,
fees for technical services which do not generate Professional Revenues) based
upon the pricing, access to, and quality of such services and shall review and
adopt the fee schedule for all ancillary services.

         (f) Provider and Payor Relationships. Subject to Section 3.7, decisions
regarding the establishment or maintenance of relationships with institutional
health care providers and payors shall be approved by the Group after
consultation with the Joint Planning Board.

priority of capital expenditures in accordance with Section 3.5(b) hereof.

         Section 5.3 Acts of the Joint Planning Board. Except as otherwise
specifically provided herein, the act of the members holding a majority of the
voting power of the Joint Planning Board shall be the act of the Joint Planning
Board. The Group agrees that, unless the following are approved in advance by
the Joint Planning Board and such act of the Joint Planning Board includes the
approval by both of the members designated by Administrator, it shall take no
action or implement any decision that would (i) require Administrator to expend
funds or incur obligations beyond those set forth under Sections 3.5 or 5.2 of
this Agreement; (ii) have a material adverse effect on the amount of
Administrator's management fee under Article VII; or (iii) otherwise have a
material adverse effect on Administrator's financial interests under this
Agreement. Except as provided in the prior sentence, the Group and Administrator
hereby agree to be bound by the act of the Joint Planning Board if such act was
approved by the members holding at least a majority of the voting power of the
Joint Planning Board. No action of the Joint Planning Board shall be effective
unless authorized by the members holding a majority of the voting power of the
Joint Planning Board present or represented by proxy at the applicable meeting.
In the event that a matter cannot be resolved by the Joint Planning Board due to
a tie vote, and no compromise can be reached, then either (x) the Board of
Directors of Parent or (y) a committee designated by the Board of Directors of
Parent containing at least one (1) physician member will make a final
determination on the matter in dispute provided that both the Group and
Administrator shall have had an opportunity to make a presentation to the Board
of Directors of Parent or a committee thereof, as applicable. A quorum of the
Joint Planning Board shall consist of the members holding a majority of the
voting power of the Joint Planning Board, present in person, by telephone, or by
proxy and the quorum must remain for the duration of the meeting.

         Section 5.4 Joint Planning Board Meetings. Meetings of the Joint
Planning Board may be held by telephone or similar communication equipment so
long as all members participating in a meeting can hear and speak to each other.

(15) business days following each meeting.

         (a) Regular Meetings. The Joint Planning Board shall hold not less than
four (4) regular meetings each year, at such specific times and places as the
members may determine.

         (b) Special Meetings. A special meeting of the Joint Planning Board may
be called by fifty percent (50%) of the votes.

<PAGE>   31


         (c) Notice Requirement. A member calling a special meeting must provide
all other members with ten (10) days' advance written or telephonic notice.
Notice must be given or sent to the member's address or telephone number as
shown on the records of the Joint Planning Board. Notice may be delivered
directly to each member or to a person at the member's principal place of
business who would reasonably be expected to communicate that notice promptly to
the member.

         (d) Waiver of Notice Requirement.

            (i) Written Waiver, Consent or Approval.  Notice of a special 
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the special meeting. Such waiver,
consent or approval need not specify the purpose of the special meeting. All
such waivers, consents, and approvals shall be filed with the Joint Planning
Board records or made a part of the minutes of the special meetings.

            (ii) Failure to Object. Notice of special meeting need not be given
to any member who attends the special meeting and does not protest before or at
the commencement of the special meeting such lack of notice.

            (iii) Quorum. The smallest number of members that hold votes that
exceed fifty percent (50%) of all voting power shall constitute a quorum of the
Joint Planning Board.

            (iv) Proxies. The Joint Planning Board shall provide for the use of
proxies, telephonic conference calls, written consents or other appropriate
methods by which the full participation of the Group members and Administrator
members can be assured.

                              Restrictive Covenants

         The parties recognize that the services to be provided by Administrator

         (f) Third Party Beneficiaries. The members of the APPI Group not party

Section 6.1, with the power to enforce the provisions hereof.

         Section 6.2 Restrictive Covenants. The Group shall obtain and enforce
formal agreements with each Physician Employee who is either (i) a Group
Physician Stockholder or (ii), to the extent permitted under applicable law, a
Full-time Physician Employee which each contain certain restrictive covenants
thereof pertaining to covenants not to compete and/or solicit with and not to
divulge the Confidential and Proprietary Information of any member of the APPI
Group or the Practice (the "Restrictive Covenants"). Except as otherwise
approved by the Joint Planning Board, each Group Physician Stockholder or
Full-time Physician Employee shall agree, during the term of his/her employment
or contractor agreement with the Practice and for a period of twenty-four (24)
months after any termination of such agreement: (i) not to establish, operate or
provide professional radiology services at any office, practice, hospital or
health care facility providing services substantially similar to those provided
by the Practice pursuant to this Agreement within 15 miles of any location of
any Practice Site(s) and (ii) to be bound by nonsolicitation, noncompetition and
nondisclosure of confidential/proprietary information and engagement of
Administrator covenants similar to those applicable to the Group as contained in
Section 6.1 hereof. Except as otherwise approved by the Joint Planning Board,
each Group Physician Stockholder or Full-time Physician Employee shall agree
that during the term of his/her employment or contractor agreement with the
Group (w) not to practice radiological medicine 


                                       30


<PAGE>   36


other than at the Premises or such other location or Practice Site(s) as
approved by the Joint Planning Board; (x) to devote substantially all of his or
her professional time, effort and ability to the Practice; (y) to request in
writing and receive in writing prior approval from the Joint Planning Board to
engage in any outside medical activities; and (z) to turn over to the Practice,
to be included in Professional Revenues attributed to the Practice, any income
derived by such Group Physician Stockholder or Full-time Physician Employee from
any outside medical activity or related source from the following medically-
related activities: teaching, consulting, medical research, inventions developed
utilizing the Group's or the Practice's time and material, testimony for
litigation, and insurance examinations. The Group shall not materially amend,
alter or otherwise change any term or provision of any Stockholder Employment
Agreement or Physician Employee Employment Agreement relating to the foregoing
covenants in this Section 6.2 without the prior written consent of
Administrator; notwithstanding the foregoing, any such amendment, alteration or
change shall not be inconsistent with the terms or provisions of this Agreement.
Following termination of this Agreement, the Group shall not amend, alter or
otherwise change any term or provision of the Restrictive Covenants, unless such
provisions are no longer in force and effect pursuant to the terms of the
applicable Stockholder Employment Agreement or Physician Employee Employment
Agreement at the time of termination of this Agreement. In the event the
Purchase Assets are acquired by the Group pursuant to Article X, the obligation
of the Group to enforce Restrictive Covenants shall be limited to enforcement of
non-solicitation and nondisclosure of confidential/proprietary information
covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Stockholder Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Stockholder Employment
Agreements and, to the extent permitted under applicable law, the Physician
Employee Employment Agreements, upon the request of Administrator, the Group
shall assign to Administrator such causes of action and/or other rights it has
related to such breach or default and shall cooperate with and provide
reasonable assistance to Administrator with respect thereto; in which case, all
costs and expenses incurred in connection therewith shall be borne by
Administrator and shall be included in Administrator Expenses, and Administrator
shall be entitled to all damages and other amounts recovered thereby. In the
event the Purchase Assets are acquired by the Group pursuant to Article X, the
obligation of the Group to enforce Restrictive Covenants shall be limited to
enforcement of non-solicitation and nondisclosure of confidential/proprietary
information covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any 


                                       31


<PAGE>   37


requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period, scope of activity restricted
and/or the geographical area applicable to such provision of the Restrictive
Covenants or this Article VI. The invalidity or non-enforceability of any
provision of the Restrictive Covenants or this Article VI in any respect shall
not affect the validity or enforceability of the remainder of the Restrictive
Covenants or this Article VI or of any other provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Stockholder or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Stockholder or Full-time Physician Employee from the restrictive
covenants contained in Section 6.2, above. In the event the Group elects to
release such Group Physician Stockholder or Full-time Physician Employee, the
Group hereby covenants that it shall obtain a formal agreement between each
Group Physician Stockholder or Full-time Physician Employee, as the case may be,
and Administrator which provides that, for a period of two (2) years following
termination of any employment agreement with the Group, such Group Physician
Stockholder or Full-time Physician Employee agrees to (a) engage Administrator
as the sole and exclusive manager and administrator of the non-medical functions
and services of said Group Physician Stockholder's or Full-time Physician
Employee's medical practice and (b) pay to Administrator the identical amount
[NY only] of revenues paid by the Group to the Administrator attributable to
such Group Physician Stockholder or Full-time Physician Employee derived from
such Group Physician Stockholder's or Full-time Physician Employee's performance
of professional medical services within 15 miles of any Practice Site.

         Section 6.6 Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary


                                       32


<PAGE>   38


information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and work effort
required and (y) the Group shall not be required to employ any Radiologist
previously associated with such Professional Service Opportunity.

         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half of the time during which the
Administrator, Parent or their Affiliates must respond to an offer described in
the Administrator's Notice, the Group shall deliver to Administrator a written
notice stating whether or not the Group elects to accept or reject the New
Professional Service Opportunity which election shall be binding on the Group.
If the Group does not elect to exercise the right or fails to provide the notice
to Administrator within the time frame herein provided, Administrator shall be
released from the right of first offer with respect to that particular New
Professional Service Opportunity. Prior to consummating any asset acquisition,
merger or other consolidation of any Radiologist, group of Radiologists, or
professional corporation or association (or other professional entity) whose
owners are Radiologists within any Secondary Service Area, Administrator shall
first consult with the Joint Planning Board.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service Opportunity as contemplated in
subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

         "Primary Service Area" shall mean that area within a five (5) mile
radius from any imaging center owned, operated or managed by Administrator,
Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.

         "Professional Service Opportunity" shall mean any opportunity to
perform professional Radiology services for any hospital, hospital system or

         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.

                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on
Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates based
upon available information for such month, and adjustments to the estimated
payments shall be made to reconcile final amounts due under Section 7.1 on the
next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and 


                                       35


<PAGE>   41


execute all necessary documents in connection with the pledge of such accounts
receivable to Administrator or at Administrator's option, its lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee and to other related provisions of
this Agreement shall be a joint decision of the parties, shall be memorialized
in a written amendment to this Agreement, and shall be based upon the
methodology used to generally determine Services Fees hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

         (a)      payment of all accrued Practice Expenses for the prior month
                  (subject to the proviso in the preceding sentence);

         (b)      payment of the Service Fee for the prior month;

         (c)      payment of the outstanding balance of all amounts advanced to
                  the Group through the end of the prior month, and applicable
                  interest thereon (as contemplated in Section 7.3); and

         (d)      payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).

all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter, the
Group or its agents shall have reasonable access during normal business hours to
the Group's and Administrator's personnel and financial records relating to the
Practice, including, but not limited to, records of collections, expenses and
disbursements as kept by Administrator in performing Administrator's obligations
under this Agreement, and the Group may copy any or all such records.

                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1 Insurance to be Maintained by the Group.

         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.

         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same


                                       38


<PAGE>   44


limits and deductibles as the insurance coverage provided pursuant to Section
9.1 upon the termination of such physician's relationship with the Group for any
reason, unless such physician was covered with an occurrence-based policy while
employed or retained by the Group. In the event that the Group, any Physician
Employee or Physician Extender Employees fails to obtain such continuing
liability insurance coverage, Administrator may do so. The cost of such
continuing liability insurance coverage shall be included in Practice Expenses
unless such cost is borne by the Physician Employee.

         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5 Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its shareholders, employees
and/or subcontractors (other than Administrator, Parent, Affiliates or their
employees, officers, directors, agents, attorneys and consultants) during the
term of this Agreement. Provided, however, that in the event an indemnification
obligation under the preceding sentence arises as of the result of any act or
omission of a person who is an officer, shareholder or other equity holder,
director, employee, agent, attorney or consultant of Administrator, Parent or
any of their Affiliates (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
the Group's indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or
incurred, that are caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts or omissions by Administrator, Parent or Affiliates and/or any of
their respective shareholders, employees and/or subcontractors (other than the
Group or its employees) during the term of this Agreement. Provided, however
that in the event an indemnification obligation under the preceding sentence
arises as a result of any act or omission of a person who is an officer,
shareholder or other equity holder, director, employee, agent, 


                                       39


<PAGE>   45


attorney or consultant of the Group (other than in connection with the
activities of the Joint Planning Board), such person shall not be entitled to
indemnification in connection therewith and any other adjustment as is equitable
shall be made to Administrator's or Parent's indemnification obligation arising
thereby.

                                    ARTICLE X

                              Term and Termination

         Section 10.1 Term of Agreement. This Agreement shall commence on the
date hereof and shall expire on the 40th anniversary hereof unless earlier
terminated pursuant to the terms of either Section 10.3 or Section 10.4 or
automatically extended pursuant to the terms of Section 10.2.

         Section 10.2 Extended Term. Unless earlier terminated as provided for
in either Section 10.3 or Section 10.4, the term of this Agreement shall be
automatically extended for additional terms of five (5) years each, unless
either party delivers to the other party, not less than twelve (12) months nor
earlier than fifteen (15) months prior to the expiration of the preceding term,
written notice of such party's intention not to extend the term of this
Agreement.

         Section 10.3 Termination by the Group. The Group may, in its sole
discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not the
obligation, to cure any Material Adminstrator Default. Notwithstanding anything
to the contrary in this Agreement, following receipt by Administrator of the
notice of a Material Administrator 


                                       40


<PAGE>   46


Default and until such Material Administrator Default shall be cured, the Group
may take such action as may be reasonably required to cover such Material
Administrator Default so as to maintain for the Group the same level of service
as before the Material Administrator Default, without prejudicing in any way the
Group's other rights and remedies, and may offset all of its costs from the
amounts which may otherwise be due to Administrator under this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that
individual from participating in or from receiving reimbursement under any
program funded by the federal government or by any state government,
notwithstanding any available post-sanction remedies, or (4) is otherwise
disciplined by any licensing, regulatory or professional entity or
institution, the result of any of which event does or 


                                      41


<PAGE>   47


is reasonably expected to materially adversely affect the Practice, the result
of any of which event described in subparagraphs (1) through (4) above, in the
absence of termination of a Physician Employee or a Physician Extender Employee
or other action of the Group to monitor and cure such act or conduct by such
employee, does or reasonably would be expected to materially and adversely
affect the Practice or the Group. Notwithstanding anything to the contrary in
this Agreement, following receipt by the Group of the notice of a Material Group
Default, and until such Material Group Default shall be cured, the Administrator
may take such action as may be reasonably required to cover such Material Group
Default so as to maintain for the Administrator the same level of service at the
Premises as before the Material Group Default, without prejudicing in any way
Administrator other rights and remedies, and may offset all of its costs of
cover from amounts which may otherwise due to the Group under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Stockholders and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee [or Physician Extender Employee] that intends to
retire prior to expiration of such five-year period, then such Physician
Employee or Physician Extender Employee shall not be counted for purposes of
determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         (b) Upon the expiration of this Agreement pursuant to Sections 10.1 or
10.2.

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to


                                       42


<PAGE>   48


require the Group to purchase from Administrator and/or Parent the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or its
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's or their Affiliates' accounting and financial records (the "Purchase
Assets"), including, but not limited to, without duplication, (i) all equipment,
furniture, fixtures, furnishings, inventory, supplies, improvements, additions
and leasehold improvements utilized by the Practice, (ii) any real estate owned
by Administrator, Parent or Affiliates that is occupied by or used primarily for
the benefit of the Practice, (iii) all unamortized intangible assets (including,
without limitation, goodwill) set forth on the financial statements of
Administrator, Parent or their Affiliates used solely in connection with the
Practice or otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and its Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c) Purchase Price. The Purchase Price shall be the lesser of (i) Fair
Market Value of the Purchase Assets subject to the assumption of the Practice
Related Liabilities or (ii) the value of the Actual Consideration (defined
below)(alternatively, the "Purchase Price"); provided, however, the Purchase
Price shall not be less than the net book value of the Purchase Assets at the
Termination Date. The Purchase Price shall be paid pursuant to Section 10.7. For
purposes of this subparagraph (c), the term "Actual Consideration" shall mean
(i) cash consideration paid to the Group pursuant to the Acquisition Agreement
and (2) an amount equal to the number of shares of Parent Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, reorganizations,
or any similar transaction whereby the Parent Common Stock is increased or
decreased or exchanged for a different number or kind of securities) issued
pursuant to the Acquisition Agreement multiplied by the fair market value of
Parent Common Stock immediately prior to the time that a Termination Notice is
provided pursuant to Section 10.7. The Purchase Price shall be appropriately
adjusted to offset and account for any monetary obligations of the Group or
Administrator owing to the other as provided herein.


                                       43


<PAGE>   49


         (d) Exercise of Option.

            (i) The Group. Upon a termination of this Agreement, the Group shall
be entitled to exercise its option to require Administrator, Parent or its
Affiliates to sell the Purchase Assets and shall assume the Practice Related
Liabilities pursuant to this Section 10.6 at any time (unless this Agreement is
terminated pursuant to Section 10.4(a) or 10.4(c)).

            (ii) Administrator. Upon termination of this Agreement, 
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

         (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at the Purchase Closing, Administrator and/or its Affiliates, as the case
may be, shall transfer and assign the Purchase Assets to the Group, and in
consideration therefor, the Group shall (a) pay to Administrator, Parent and/or
their Affiliates an amount in cash or, at the option of the Group (subject to
the conditions set forth below), Parent Common Stock (valued pursuant to Section
10.6(c) hereof), or some combination of cash and Parent Common Stock equal to
the Purchase Price and (b) assume the Practice Related Liabilities. The
structure of the transaction set forth in this Section 10.7 shall, if possible,
be structured as a tax-free transaction under applicable law. Each party shall
execute such documents or instruments as are reasonably necessary, in the
opinion of each party and its counsel, to effect the foregoing transaction. The
Group shall, and shall use its best efforts to cause each shareholder of the
Group to, execute such documents or instruments as may be necessary to cause the
Group to assume the Practice Related Liabilities and to release Administrator,
Parent and/or their Affiliates, as the case may be, from any liability or
obligation with respect thereto. In the event the Group desires to pay all or a
portion of the Purchase Price in shares of Parent Common Stock, such transaction
shall be subject to the satisfaction of each of the following conditions:

         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims,


                                       44


<PAGE>   50


proxies, options, stockholders' agreements and encumbrances (not including any
applicable securities restrictions and lock-up arrangements with the Parent or
any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain financing for such acquisition but is unable to
obtain such financing and (iii) there is either a Material Administrator Default
pursuant to Section 10.3(a) or (c) or a Material Group Default pursuant to
Section 10.4(b) triggering a sale of the Purchase Assets, the Group shall be
entitled to obtain financing from Administrator, Parent and/or their Affiliates,
but only for the difference between the Fair Market Value of the Purchase Assets
and the net book value of the Purchase Assets. The terms of such financing shall
be for a five (5) year period at an interest rate equal to the prime rate (as
published in the Wall Street Journal) plus four percent (4%) or such lesser rate
as is required to be in conformance with all applicable state and federal law.
In the event the Group is entitled to obtain financing from Administrator,
Parent and/or their Affiliates, the Group shall execute and deliver to
Administrator, Parent and/or their Affiliates all such documentation necessary
and appropriate to effectuate the financing transaction including, without
limitation, a secured promissory note, security agreement and financing
statements and such documentation shall contain such representations, warranties
and conditions customary to a secured transaction of this size.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator, Parent and/or their Affiliates to the
Group or the Group to the Administrator, Parent and/or their Affiliates
(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value),


                                       45


<PAGE>   51


except with respect to the obligations set forth below. The foregoing to the
contrary notwithstanding:

         (a) Administrator, Parent and/or their Affiliates shall use their best
efforts to cooperate with the Group for the appropriate transfer of management
services.

         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.

         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.

                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

         Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means set forth in Section 11.1 and prior to commencing
an arbitration procedure pursuant to this Article XI, the parties 


                                       46


<PAGE>   52


shall meet to discuss and consider other alternative dispute resolution
procedures other than arbitration, provided, however that if the parties hereto
agree to an alternative to arbitration they may agree to an alternative set of
rules, including rules of evidence and procedure. If at any time prior to the
rendering of the decision by the arbitrator (or pursuant to such other
alternative dispute resolution procedure) as contemplated in this Article XI to
the extent a party makes a written offer to the other party proposing a
settlement of the matter(s) at issue and such offer is rejected, then the party
rejecting such offer shall be obligated to pay the costs and expenses (excluding
the amount of the award granted under the decision) of the party that offered
the settlement from the date such offer was received by such other party if the
decision is for a dollar amount that is less than the amount of such offer to
settle. Notwithstanding the foregoing, the terms and provisions of this Article
XI shall not preclude any party hereto from seeking, or a court of competent
jurisdiction from granting, a temporary restraining order, temporary injunction
or other equitable relief for any breach of (i) any noncompetition or
confidentiality covenant or (ii) any duty, obligation, covenant, representation
or warranty, the breach of which may cause irreparable harm or damage.

         Section 11.3 Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among Administrator and the Group arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within 30 days of notice
by a party to the other of its desire to seek arbitration under this Article XI
one arbitrator mutually acceptable to Administrator and the Group to hear and
decide all such claims under this Article XI. If such matter or action involves
health-care issues, then the arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators proposed shall be impartial
and independent of all parties. If the parties cannot agree on the selection of
an arbitrator within said 30-day period, then any party may in writing request
the judge of the United States District Court for the District of Maryland,
Baltimore County, senior in term of service to appoint the arbitrator and,
subject to this Article XI, such arbitrator shall hear all arbitration matters
arising under this Article XI.

         Section 11.4 Applicable Rules.

         (a) Each arbitration hearing shall be held at a place in Maryland
acceptable to the arbitrator. The arbitration shall be conducted in accordance
with the Commercial Arbitration Rules of the American Arbitration Association to
the extent such rules do not conflict with the terms hereof. The decision of the
arbitrator shall be reduced to writing and shall be binding on the parties and
such decision shall contain a concise statement of the reasons in support of
such decision. Judgment upon the award(s) rendered by the arbitrator may be
entered and execution had in any court of competent jurisdiction or application
may be made to such court for a judicial acceptance of the award and an order of
enforcement. The charges and expenses of the arbitrator shall be shared equally
by the parties to the hearing.

         (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI. In
fulfilling his duties with respect to determining the amount of any loss, the
arbitrator may consider such matters as, in the opinion of the arbitrator, are
necessary or helpful to make a proper valuation. The arbitrator may consult with
and engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

         (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.

         (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e) All privileges under Maryland and federal law, including attorney-
client and work-product privileges, shall be preserved and protected to the same
extent that such privileges would be protected in a federal court proceeding
applying Maryland law.

                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment.

         (a) Administrator shall have the right to assign its rights hereunder
to Parent or any direct or indirect wholly-owned subsidiary of Administrator or
Parent (that remains a wholly-owned subsidiary of Administrator or Parent) or to
a financial institution as collateral security for the indebtedness of Parent,
Administrator or their Affiliates without the consent of the Group. No
assignment under subsection (a) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         (b) Administrator, Parent and their Affiliates shall provide notice to
the Group of Administrator's intent (i) to assign this Agreement (other than as
permitted in Section 12.1(a) herein), (ii) sell all or substantially all of the
assets of Administrator or (iii) effectuate a consolidation, merger or sale of a
majority of the capital stock of Administrator as soon as practicable following
a decision by the Parent's and Administrator's respective boards of directors to
seek such assignment or sale. The assignment of this Agreement (other than as
permitted in Section 12.1(a)), the sale of all or substantially all of the
assets of Administrator by Parent or a 


                                       48

<PAGE>   54


consolidation, merger or sale of a majority of the capital stock of
Administrator shall not be permitted unless Administrator shall give written
notice to the Group stating the party who made the offer and specifying the
purchase price offered (the "Notice"). The Group shall have the option to
repurchase the Purchase Assets on the same terms and conditions set forth in the
Notice. In the event the Group fails to provide written notice to Administrator
of its intent to exercise its option to repurchase the Purchase Assets pursuant
to this Section 12.1 within the earlier of (i) thirty (30) days or (ii) one-half
of the time during which Administrator, Parent or their Affiliates must respond
to an offer following the Group's receipt of the Notice, the option contained in
this Section 12.1 shall be deemed null and void and of no further force and
effect, and Administrator shall be free to assign the Agreement, sell all or
substantially all of the assets of Administrator or sell or transfer all of the
capital stock Administrator without the consent of the Group. No assignment
under this subsection (b) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

         Section 12.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 12.4 Additional Documents. Each of the parties hereto agrees to
execute any document or documents that may be reasonably requested from time to
time by the other party to implement or complete such party's obligations
pursuant to this Agreement.

         Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,
costs and expenses including, but not limited to, attorney's fees, costs and
expenses for trial, appellate proceedings and negotiations, in addition to any
other relief granted.

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group
and Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this
Agreement should be construed or deemed, by any governmental authority, agency
or court to constitute the practice of medicine, the performance of said act or
service by Administrator shall be deemed waived and forever unenforceable and
the provisions of this 


                                       49


<PAGE>   55


Section 12.6 shall be applicable. Neither party shall claim or assert illegality
as a defense to the enforcement of this Agreement or any provision hereof;
instead, any such purported illegality shall be resolved pursuant to the terms
of this Section 12.6 and Section 12.9.

         Section 12.7 Parties In Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto. Except
as provided in Section 6.1(g), neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party hereto
or thereto any rights or remedies hereunder or thereunder.

         Section 12.8 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

         Section 12.9 Severability. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 12.10 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULE GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF MARYLAND.

         Section 12.11 No Waiver; Remedies Cumulative. No party hereto shall by
any act (except by written instrument pursuant to Section 12.3 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default in or breach of any of the terms
and conditions hereof. No failure to exercise, nor any delay in exercising, on
the part of any party hereto,. any right, power or privilege hereunder shall
operate as a waiver thereof. No single or partial exercise of any right, power
or privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. No remedy set forth in this
Agreement or otherwise conferred upon or reserved to any party shall be
considered exclusive of any other remedy available to any party, but the same
shall be distinct, separate and cumulative and may be exercised from time to
time as often as occasion may arise or as may be deemed expedient.

acknowledge that neither Administrator nor Parent is authorized or qualified to
engage in any activity which may be construed or deemed to constitute the

required of Administrator is construed or deemed to constitute the practice of
medicine, Administrator is released from any obligation to provide, and the

arrange for the services set forth in this Article III, and the costs, fees,
expenses and other disbursements incurred by Administrator or Parent in
connection therewith shall be included in Practice Expenses, except to the
extent such costs, fees or expenses are expressly included in Excluded Practice
Expenses or Administrator Expenses.  Administrator is authorized to perform its
services hereunder as is necessary or appropriate for the efficient operation
of the Practice, including, without limitation, performance of some of the
business office functions at locations other than the Practice.  Except to the
extent necessary to comply with applicable laws, regulations or professional
ethical standards, the Group will not act in a manner which would prevent
Administrator from performing its duties hereunder and will provide such
information and assistance to Administrator as is reasonably required by
Administrator to perform its services hereunder.  Administrator shall cause its
employees, to comply with all applicable federal, state and local laws, rules
and regulations in Administrator's provision of services hereunder.

         (b)     Alternative Management Arrangements.

                 (i)        If Administrator fails to perform, provide or
arrange for the services set forth in this Article III in a manner reasonably
consistent with commercially available services offered by third party
providers of physician practice management services of the type and scope
offered by Administrator, then the Group shall provide written notice of such
event to Administrator, Parent or their Affiliates, including reasonable
evidence of such commercially available services.  Administrator shall deliver
to the Group within thirty (30) days after receipt by Administrator of such
written notice a written plan detailing the methods and procedures
Administrator, Parent or their Affiliates shall utilize to restore the level of
service contemplated by this Agreement.  In the event Administrator fails to
restore the level of service contemplated by this Agreement in accordance with
such plan submitted or in any event within ninety (90) days, the Group shall





                                       10

be entitled to reimbursement by Administrator for the reasonable costs and
expenses of obtaining such service on a temporary basis until such time
Administrator demonstrates its ability to perform such service at the level
contemplated by this Agreement.  Nothing contained in this subsection (b)(i)

Administrator Default pursuant to Section 10.3(b) of this Agreement.

                 (ii)       If Administrator is unable to perform or is
released from performing any service which is required of Administrator because

Administrator shall deliver to the Group notice of such an event.  The Group
shall be entitled to reimbursement by Administrator for the reasonable costs
and expenses of obtaining such services until such time Administrator is able
to perform or provide such service in accordance with applicable law.

aspects of the Practice.  Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice.  Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function.  Administrator may, however, advise the Group as to the

connection with the Practice at the Premises or any Practice Site(s) (including
all fees generated by both the Technical Operations and the Professional
Operations), for services performed outside the Practice for its hospitalized
patients, and for all other professional and Practice services.  The Group
hereby





                                       11
<PAGE>   17
appoints Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:

                            (A)     to bill patients, insurance companies,
Managed Care Payors, and other third-party payors in the Group's name and on
its behalf;

                            (B)     to collect accounts receivable resulting
from such billing not otherwise purchased by Administrator (as provided for in
Section 3.2(e) hereof) in the Group's name and on its behalf;

                            (C)     to receive payments on behalf of the Group
from insurance companies, prepayments received from health care plans,
Medicare, Medicaid, Managed Care Payors and all other third-party payors;

                            (D)     to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                            (E)     to take possession of and endorse in the
name of the Group and deposit into the Deposit Account (and/or in the name of
an individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                            (F)     upon the prior consent of the Group, which
consent shall not be unreasonably withheld or delayed, to initiate the
institution of legal proceedings in the name of the Group or a Physician
Employee to collect any accounts and monies owed to the Group or the Physician
Employee, to enforce the rights of the Group or the Physician Employee, as the
case may be, as creditor under any contract or in connection with the rendering
of any service, and to contest adjustments and denials by governmental agencies
(or their fiscal intermediaries) as third-party payors.

                 (ii)       The Group hereby appoints Administrator as its true
and lawful attorney-in-fact to deposit into the Deposit Account all
Professional Revenues and Technical Revenues collected by Administrator as
provided for in this Section 3.2(b).  The Group covenants, and shall cause all
Physician Employees and Physician Extender Employees to covenant, to forward
any payments received with respect to any Professional Revenues or Technical
Revenues generated for services provided by the Group or any of its Physician
Employees and Physician Extender Employees to Administrator for deposit.
Administrator shall have the right to withdraw funds from the Deposit Account
and all owners of the Deposit Account shall execute a revocable standing
transfer order (the "Transfer Order") under which the bank maintaining the
Deposit





                                       12
<PAGE>   18
Account shall periodically transfer the entire balance of the Deposit Account

Account").  The Group and Administrator hereby agree to execute from time to
time such documents and instructions as shall be required by the bank
maintaining the Deposit Account and mutually agreed upon to effectuate the
foregoing provisions and to extend or amend such documents and instructions.
Any action by the Group that materially interferes with the operation of this
Section, including but not limited to, any failure to deposit or to have
Administrator deposit any Professional Revenues and/or Technical Revenues into
the Deposit Account, any withdrawal of any funds from the Deposit Account not
authorized by the express terms of this Agreement or any other written
agreement executed by each of the parties, or any revocation of or attempt to
revoke the Transfer Order (otherwise than upon expiration or termination of
this Agreement), will constitute a breach of this Agreement and will entitle
Administrator, in addition to any other remedies it may have at law or in
equity, to seek a court ordered assignment of the rights provided to
Administrator pursuant to subparagraph (i) above.

                 (iii)      All monies shall be accounted for by Administrator
as being distinctly attributable to the Group.  The Group may perform the
functions or exercise the rights set forth in this Section 3.2(b) only with the
prior written consent of Administrator.  The Group shall execute such documents
in form and substance as approved by Administrator and its legal counsel to
permit Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b).  The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein.  In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c)     Accounting.  Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of

equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and

that Administrator disburse funds in fulfillment of the obligations of the
Group and Administrator under this Agreement.

all times during and after the term of this Agreement, including any extensions
or renewals hereof, all business records, including but not limited to,
business agreements, books of account, personnel records, general
administrative records and all information generated under or contained in the
management information system pertaining to Administrator's obligations
hereunder, and other business information of Administrator of any kind or
nature, except for patient medical records and the Group's Records (as defined

information, including the right to obtain copies thereof in any media
reasonably requested by the Group, for any purpose related to patient care or
the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years.  Administrator hereby
agrees to preserve the confidentiality of such patient medical records and to
use the information in such records only for the limited purposes necessary to
perform management services and, within the limits of its responsibilities
hereunder, to ensure that provision is made for appropriate care for patients
of the Practice.

                 (ii)       The Practice's Business and Financial Records.  At

to which it has access pursuant to this subparagraph (iii).

                 (iv)       Compliance with Law.  The management of all files

         (h)     Collections.  Subject to the consent requirement contained in
Section 3.2(b)(i)(F),  Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees
and pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

         Section 3.3        Facilities.

         (a)     Premises.  Administrator shall make available to the Group the
Premises that are described in Exhibit 3.3(a) attached hereto and such other
improvements made by Administrator or Parent for the use of the Group
hereunder.  The Premises shall be subject to such expansion or reduction as
reviewed and approved by the Joint Planning Board.  Administrator shall obtain
for the Group all utilities reasonably required in connection with the use of
the Premises and shall provide for the proper cleanliness of the Premises,
including normal janitorial and maintenance services and refuse disposal,
including medical waste.  Administrator shall maintain the Premises in good
condition and make or cause to be made all necessary repairs thereto.

         (b)     Personal Property.  Administrator shall provide the Group with
the use of the equipment, furniture, fixtures, furnishings and other personal

acquired by Administrator or Parent (subject to review and approval of the
Joint Planning Board) for the use of the Group pursuant to the terms hereof
(collectively, the "Personal Property").  Administrator shall maintain the
Personal Property in good condition and make or cause to be made all necessary
repairs thereto.

         (c)     Expenses.  All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the

refuse disposal, real or personal property lease cost payments and expenses,
interest, refinancing expenses, depreciation, loss on disposition of assets,

connection with the Professional Operations, the costs and expenses associated
with such usage shall be allocated between Professional Expenses and Technical
Expenses as approved by the Joint Planning Board.

         (d)     Disposition.  Subject to provisions contained in existing
agreements to which Administrator or Parent is or becomes a party and, where
necessary and appropriate for the efficient operation of





                                       16
<PAGE>   22
the Practice, nothing herein shall be construed as precluding Administrator or
Parent from selling, leasing or otherwise disposing of all or any part of the
Premises, Personal Property, real property, improvements, trade names,
trademarks and other intangible property; provided, however, any such sale,
lease or disposition shall be subject to the prior review and approval of the
Joint Planning Board and shall not eliminate or diminish Administrator's
obligations hereunder.

         (e)     No Warranties or Representations.  The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

         Section 3.4        Acquisition and Assistance.

         (a)     Employment of Physicians.  Subject to consultation with the
Joint Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice.  Subject to
consultation with the Joint Planning Board, in the event that a decision is
made by the Group to pursue the employment of selected physicians, if requested
by the Group, Administrator will provide recruiting, consulting, negotiating
and other advisory services in connection with such transaction.
Notwithstanding the preceding, as set forth in and subject to the provisions of
Section 4.1 hereof, the Group shall have complete control of and responsibility
for the hiring of all Physician Employees and Physician Extender Employees.

         (b)     Acquisitions.  In the event that the Group contemplates
acquiring or affiliating with a physician group, practice or other entity, and
such acquisition or affiliation involves the use or expenditure of
Administrator's and/or Parent's cash or other resources including the
assumption of any Practice Expenses or liabilities incurred or reasonably
expected to be incurred as a result of such an acquisition or affiliation
including, without limitation, capital and personnel (collectively, the
"Resources"), then the Group shall first consult with the Joint Planning Board
and Administrator, and any decision to make such affiliation or acquisition
shall be subject to prior approval of Administrator, which decision of the
Administrator shall be provided to the Group in a reasonable and timely manner
following satisfactory review of the physician group, practice or other entity
to be acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto.  If such contemplated acquisition or affiliation does not
involve the use or expenditure





                                       17
<PAGE>   23
of any of Administrator's and/or Parent's Resources, then such decision shall
be in the sole discretion of the Group.  Notwithstanding any provision
contained herein to the contrary, any person or entity with which the Group
affiliates or acquires shall be subject to the terms and conditions of this
Agreement.  If a decision is made to proceed with any affiliation or
acquisition of a physician group or practice, the Group may seek from
Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

         Section 3.5        Financial Planning and Budgeting.

         (a)     Budgeting.  Administrator shall collaborate with the Group and
the Joint Planning Board in the preparation of all annual capital and operating
budgets.  These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors.  For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board.
The projected annual operating budget for each subsequent year shall be subject
to the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice.  For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

         (b)     Capital Expenditures.  Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

                 (i)        Budgeted Expenditures.  All budgeted capital
expenditures and improvement projects shall be subject to final review and
approval by the Joint Planning Board prior to the making of any actual
expenditure.  Such review and approval shall be based on confirming that the
assumption, facts and circumstances on which the decision to budget for such
expenditure was based still support and justify the actual expenditures.

                 (ii)       Non-Budgeted Expenditures.  Requests for
non-budgeted capital expenditures and improvement projects shall be evaluated
and prepared by the Joint Planning Board in consultation





                                       18
<PAGE>   24
with the Group and Administrator.  All requests for non-budgeted capital
expenditures and improvements at or for the benefit of the Practice in excess
of either $75,000 individually or an aggregate amount equivalent to $2,500
multiplied by the number of Full-time Physician Employees employed at the time
the capital budget for such Group for the applicable year is determined
(provided, however, that such aggregate amount shall not exceed $250,000 for
any calendar year) must be approved by the Board of Directors of Parent or by
any committee specifically designated by the Board of Directors of Parent for
such purposes.

         (c)     Capital Improvements and Expansion.  Subject to Section
3.5(b), any site or Premises renovation, expansion or reduction plans and/or
capital equipment expenditures with respect to the Practice shall be reviewed
and approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6        Personnel.  Administrator shall provide
non-physician professional support (other than Physician Extender Employees)
including, without limitation, nurses, technologists, physicists and
administrative, clerical, secretarial, bookkeeping and collection personnel as
is reasonably necessary for the efficient conduct of the Practice's operations.
All such personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law.  Such personnel shall be employees of Administrator, and Administrator
shall determine and cause to be paid the salaries and benefits of all such
personnel.  Such personnel shall be supervised by and comply with the
directions and orders of Administrator, except as otherwise required by
applicable law.  If the Group is dissatisfied with the services of any such
personnel who provide services primarily for the Practice at the Premises, the
Group shall consult with Administrator, and Administrator shall in good faith
determine whether the performance of that employee could be brought to
acceptable levels through counsel and assistance, or whether such employee
should be considered for termination.  If Administrator determines to retain
such employee and the Group is still dissatisfied with the services provided by
such employee after a reasonable period of time, Administrator shall either
relocate such employee or otherwise cease to utilize such employee in providing
services to the Practice hereunder.  Administrator shall maintain established
working relationships wherever possible and Administrator shall make every
effort consistent with sound business practices to honor the specific requests
of the Group with regard to the assignment of Administrator's employees.

         Section 3.7        Provider and Payor Relationships.  Administrator
shall provide financial and business assistance to the Group in the
negotiation, establishment, supervision and maintenance of contracts and
relationships (collectively, the





                                       19
<PAGE>   25
"Managed Care Contracts") with all managed care, institutional health care
providers and payors, health maintenance organizations, preferred provider
organizations, exclusive provider organizations, Medicare, Medicaid, insurance
companies, hospitals and other similar persons (collectively, "Managed Care
Payors").  Approval, disapproval, termination or amendment of any contract or
relationship of such Managed Care Payors with the Group shall, after
consultation with the Joint Planning Board, be the responsibility of the Group.
Notwithstanding the preceding language, if a contract or relationship between
any Managed Care Payor and the Group involves or affects a contract or
relationship with any other physician group or practice serviced or managed by
Administrator, Parent or any of their Affiliates (the "Other Practices") and a
consensus among the Group and the Other Practices cannot be reached regarding
the contract or relationship, then the ultimate decision as to the approval,
disapproval, termination or amendment of such contract or relationship
involving the Group, the Other Practices and such Managed Care Payor shall be
determined by the affirmative vote of the Physician Board Members (as defined
below) who hold a majority of the Group Voting Power (as defined below).  For
purposes of this Section 3.7, (i) the term "Physician Board Members" shall mean
(a) those members appointed by the Group who serve on the Joint Planning Board
and (b) those persons appointed by the Other Practices who serve on the Other
Practices' joint boards (in a similar capacity to the Joint Planning Board) as
part of their contractual relationship with Parent, Administrator or any of
their Affiliates, and (ii) the term "Group Voting Power" shall mean the total
voting percentage which may be cast by the Physician Board Members on a
collective basis, with the percentage of votes able to be cast by any Group or
Other Practice, as applicable, shall be equal to the quotient determined by
dividing (x) the total estimated annual professional revenues to be generated
by the Group from such Managed Care Contract as determined by Administrator,
Parent or their Affiliates, as appropriate, in its sole discretion, by (y) the
total estimated annual professional revenues to be generated by the Group and
all Other Practices from such Managed Care Contract as determined by the
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion.

         Section 3.8        Inventory and Supplies.  Administrator shall order,
purchase and provide to the Group on a timely basis inventory and supplies, and
such other ordinary, necessary or appropriate materials which are requested by
the Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator.  Such inventory, supplies and other materials shall be included
in Practice Expenses at their cost to Parent or Administrator, as the case may
be.

         Section 3.9        Advertising and Public Relations.  In consultation
with the Joint Planning Board, Administrator shall implement (and design where
requested) an appropriate local public





                                       20
<PAGE>   26
relations or advertising program on behalf of the Practice, with appropriate
emphasis on public awareness of the availability of services at the Practice.
Prior to publication or distribution of such marketing or public relations
material or information, Administrator shall submit such material to the Group
for its review and approval, which shall not be unreasonably withheld.
Administrator shall also design and implement all national or other non-local
public relations or advertising programs on behalf of the Practice, the cost of
which shall be included in Administrator Expenses, except to the extent such
national programs are reasonably designed to replace or supplement the
marketing benefits derived from local public relations or advertising programs,
in which case, a pro rata share of such costs will be included in Practice
Expenses as determined by the Joint Planning Board.  The parties hereto agree
that all public relations and advertising programs shall be conducted in
compliance with applicable standards of medical ethics, laws and regulations.

         Section 3.10       Quality Assurance.  Subject to Article II,
Administrator shall assist the Group in fulfilling its obligations to its
patients to maintain a high quality of medical and professional services.  Any
expenses that are related to the overall maintenance of Administrator's quality
assurance program shall be included in Administrator Expenses; provided,
however, that any expenses related to such program that are incurred for
services provided solely for the direct benefit of the Practice shall be
included in Practice Expenses.

         Section 3.11       Other Consulting and Advisory Services.
Administrator will provide such consulting and other advisory services as
reasonably requested by the Group in all areas of the Group's business
functions, including, without limitation, financial planning, acquisition and
expansion strategies, development of long-term business objectives and other
related matters.

         Section 3.12       Events Excusing Performance.  In the event of
strikes, lock-outs, calamities, acts of God, unavailability of supplies or
other events over which Administrator has no control, Administrator shall not
be liable to the Group for failure to perform any of the services required
hereunder and the Group shall not have the right to terminate this Agreement
pursuant to Section 10.3(b), for so long as such events continue and for a
reasonable period of time thereafter; provided however that if such events
continue and Administrator is not able to perform any material portion of the
services required hereunder for a period of 120 consecutive days or more,
either Administrator or Group may terminate this Agreement by written notice to
the other.

                            Obligations of the Group

         Section 4.1        Employment of Physician Employees and Physician
Extender Employees.  Except as set forth in Article V, the Group shall have
complete control of and responsibility for the hiring, compensation,
supervision, training, evaluation and termination of its Physician Employees
and Physician Extender Employees.  The Group shall conduct an appropriate and
reasonable due diligence review in connection with the hiring of any physician
or the acquisition of any physician group or practice.  Although Administrator
may provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now
or hereafter applicable to their employment.  The Group and its Physician
Employees and Physician Extender Employees shall not have any claim under this
Agreement or otherwise against Administrator or Parent for workers'
compensation, unemployment compensation or Social Security benefits, all of
which shall be the sole responsibility of the Group.  The Group shall only
employ or contract with licensed physicians or other persons meeting applicable
credentialing guidelines established by the Group after consultation with the
Joint Planning Board.  The Group shall cooperate in the obtaining and retaining
of professional liability insurance by ensuring that its Physician Employees
and Physician Extender Employees, and other employees who may have malpractice
exposure or liability, are insurable and by participating in an ongoing risk
management program.

         Section 4.2        Professional Services.  The Group shall provide
professional services to its patients in compliance at all times with ethical
standards, laws, rules and regulations applicable to the operations of the
Practice, the Physician Employees and Physician Extender Employees.  The Group
shall ensure that each Physician Employee and each Physician Extender Employee
has all required licenses, credentials, approvals or other certifications to
perform his or her duties and services for the Practice and, in the event that
the Group becomes aware of any disciplinary actions or medical malpractice
actions initiated against any Physician Employee or Physician Extender
Employee, the Group shall promptly inform Administrator of such action and the
underlying facts and circumstances.  If required by applicable law, any state
or federal regulatory agency or any contractual obligations, the Group shall
carry out a program to monitor the quality of medical care practiced at the
Practice; provided, however, that the preceding language shall not limit the
Group's obligation to participate in or comply with any programs established by
Administrator or Parent for purposes of ensuring that the Group complies with
applicable law.  The Group shall employ Physician Employees and Physician
Extender Employees as is





                                       22
<PAGE>   28
necessary to provide efficient medical care to patients of the Practice.

         Section 4.3        Medical Practice.  The Group shall use and occupy
the Premises exclusively for the practice of medicine and for providing other
related services and products.  Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional
medical practice or practices conducted at the Premises shall be conducted
solely by Physician Employees, and, no other physician or medical practitioner
shall be permitted to use or occupy the Premises; provided, however, if any
test or procedure is required to be performed jointly with another physician
who is not a Physician Employee or Physician Extender Employee, then such
physician may use and occupy the Premises for purposes of performing such
procedure or test so long as the Group receives usual and customary fees in
connection with such procedure or test.  The Group shall be solely and
exclusively in control of all aspects of the practice of medicine and the
delivery of medical services at the Group's facilities and at such outpatient
surgery centers, acute care hospitals and other facilities as the Group may
deem appropriate from time to time.  The rendition of all professional medical
services, including, but not limited to, diagnosis, treatment, therapy, the
prescription of medicine and drugs, and the supervision and preparation of
medical reports shall be the sole responsibility of the Group.  From time to
time the Group, after consultation with the Joint Planning Board, will adopt
and implement fee schedules for (i) non-prepaid patients which shall be
reasonable in relation to fees generally being charged in the same or similar
market areas and (ii) for all rebillings and recovery items on prepaid Managed
Care Contracts which are authorized and permitted by such contracts.  A copy of
such agreements and any amendment thereto shall be provided to Administrator
for review no later than thirty (30) days prior to the proposed effective date
thereof.

         Section 4.4        Group's Internal Matters.  The Group shall be
responsible for matters involving its corporate governance, employees and
similar internal matters, including, but not limited to, preparation and
contents of such reports to regulatory authorities governing the Group that the

among the Group Physician Stockholders, disposition of the Group's property and
stock (subject to any restrictions contained herein), hiring and firing of its
employees, licensing and implementing all compliance plans and procedures as

which will be included in Excluded Practice Expenses, the costs incurred in
connection with the foregoing matters shall be Practice Expenses.

foregoing, the Group shall comply and shall cause each Physician Employee,

for the furnishing or arranging for the furnishing of any item or service for
which payment may be made in whole or in part by Medicare or Medicaid, or (ii)
in return





                                       24

without the express written consent of Administrator, which consent shall not
be unreasonably withheld.

         Section 4.10       Events Excusing Performance.  In the event of
strikes, lock-outs, calamities, acts of God, unavailability of supplies or

         Section 5.1        Formation and Operation of the Joint Planning
Board.

         (a)     The parties hereto shall establish the Joint Planning Board
which shall be responsible for developing long-term strategic planning
objectives and management policies for the overall operation of the Practice
and shall facilitate communication and interaction between Administrator and
the Practice.  The Joint Planning Board shall consist of no less than three (3)
or more than six (6) members.  Administrator shall designate, in its sole
discretion, two (2) members of the Joint Planning Board, who shall serve at the
pleasure of Administrator and who may be removed or replaced by Administrator
at any time.  The Group shall designate, in its sole discretion, no less than
one (1) or more than four (4) members of the Joint Planning Board, who shall
serve at the pleasure of the Group and who may be removed and replaced by the
Group at any time.  Each member appointed by Administrator shall be entitled to
one (1) vote per member, and each member appointed by the Group shall be
entitled to that number of votes equal to the quotient determined by dividing
(x) two (2) votes by (y) the number of members designated by the Group to the
Joint Planning Board.  The act of the members holding a majority of the voting
power of the Joint Planning Board shall be the act of the Joint Planning Board.

         (b)     Each member of the Joint Planning Board shall have the right
to vote on every matter either in person, by telephone, by written consent or
by one or more agents, who are also members of the Joint Planning Board,
authorized by a written proxy signed by the member and filed with the Joint
Planning Board.  A proxy shall state that it either shall be voted for or
against a specific matter or matters identified in the proxy or shall be voted
identically to the vote of the agent specified in the proxy on any and all
matters that may come before and be voted on by the Joint Planning Board.  A
validly executed proxy which does not state that it is irrevocable shall
continue in full force and effect unless (i) revoked by the member executing
it, before the vote pursuant to that proxy, by a writing delivered to the Joint
Planning Board stating that the proxy is revoked, or by a subsequent proxy
executed by, or attendance at the meeting and voting in person by, the member
executing the proxy; or (ii) written notice of the death





                                       26
<PAGE>   32
or incapacity of the maker of that proxy is received by the Joint Planning
Board before the vote pursuant to that proxy is counted; provided, however,
that no proxy shall be valid after the expiration of eleven (11) months from
the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2        Duties and Responsibilities of the Joint Planning
Board.  The Joint Planning Board shall advise the Group on the following
matters:

         (a)     Capital Improvements and Expansion.  Subject to Section
3.5(b), any site or Premises renovation, expansion or reduction plans and/or
capital equipment expenditures with respect to the Practice shall be reviewed
and approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         (b)     Annual Budgets.  The Joint Planning Board shall collaborate
with Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board.  For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in
excess of five percent (5%) to the annual capital or operating budgets.

         (c)     Advertising.  The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

         (d)     Patient Fees.  As a part of the annual operating budget, in
consultation with and upon recommendation of the Joint Planning Board, the
Group shall review and adopt the fee schedule for all professional services
rendered by the Practice.

         (e)     Ancillary Services and Fees.  The Joint Planning Board shall
approve  Practice-provided non-medical ancillary services (including, without
limitation, fees for technical services which do not generate Professional
Revenues) based upon the pricing, access to, and quality of such services and
shall review and adopt the fee schedule for all ancillary services.

         (f)     Provider and Payor Relationships.  Subject to Section 3.7,
decisions regarding the establishment or maintenance of relationships with
institutional health care providers and payors shall be approved by the Group
after consultation with the Joint Planning Board.

         (g)     Strategic Planning.  The Joint Planning Board shall develop a
plan which depicts the strategic direction of the





                                       27
<PAGE>   33
Practice, as updated from time to time.  Such plan will, among other things,
identify opportunities, objectives, and the resources required to effect such
plan.

         (h)     Capital Expenditures.  The Joint Planning Board shall
determine the priority of capital expenditures in accordance with Section
3.5(b) hereof.

         (i)     Provider Hiring.  The Joint Planning Board shall consult with
the Group to recommend the number and type of Physician Employees and Physician
Extender Employees required for the efficient operation of the Practice.

         (j)     Non-Physician Personnel.  The Joint Planning Board shall
consult with Administrator to recommend the number and type of non- physician
employees required for the efficient operation of the Practice.

         Section 5.3        Acts of the Joint Planning Board.  Except as
otherwise specifically provided herein, the act of the members holding a
majority of the voting power of the Joint Planning Board shall be the act of
the Joint Planning Board.  The Group agrees that, unless the following are
approved in advance by the Joint Planning Board and such act of the Joint
Planning Board includes the approval by both of the members designated by
Administrator, it shall take no action or implement any decision that would (i)
require Administrator to expend funds or incur obligations beyond those set
forth under Sections 3.5 or 5.2 of this Agreement; (ii) have a material adverse
effect on the amount of Administrator's management fee under Article VII; or
(iii) otherwise have a material adverse effect on Administrator's financial
interests under this Agreement.  Except as provided in the prior sentence, the
Group and Administrator hereby agree to be bound by the act of the Joint
Planning Board if such act was approved by the members holding at least a
majority of the voting power of the Joint Planning Board.  No action of the
Joint Planning Board shall be effective unless authorized by the members
holding a majority of the voting power of the Joint Planning Board present or
represented by proxy at the applicable meeting.  In the event that a matter
cannot be resolved by the Joint Planning Board due to a tie vote, and no
compromise can be reached, then either (x) the Board of Directors of Parent or
(y) a committee designated by the Board of Directors of Parent containing at
least one (1) physician member will make a final determination on the matter in
dispute provided that both the Group and Administrator shall have had an
opportunity to make a presentation to the Board of Directors of Parent or a
committee thereof, as applicable.  A quorum of the Joint Planning Board shall
consist of the members holding a majority of the voting power of the Joint
Planning Board, present in person, by telephone, or by proxy and the quorum
must remain for the duration of the meeting.

law, a Full-time Physician Employee which each contain certain restrictive
covenants thereof pertaining to covenants not to compete and/or solicit with
and not to divulge the Confidential and Proprietary Information of any member
of the APPI Group or the Practice (the "Restrictive Covenants").  Except as
otherwise approved by the Joint Planning Board, each Group Physician
Stockholder or Full-time Physician Employee shall agree, during the term of
his/her employment or contractor agreement with the Practice and for a period
of twenty-four (24) months after any termination of such agreement:  (i) not to
establish, operate or provide professional radiology services at any office,
practice, hospital or health care facility providing services substantially





                                       34
<PAGE>   40
similar to those provided by the Practice pursuant to this Agreement within 15
miles of any location of any Practice Site(s) and (ii) to be bound by
non-solicitation, noncompetition and nondisclosure of confidential/proprietary
information and engagement of Administrator covenants similar to those
applicable to the Group as contained in Section 6.1 hereof.  Except as
otherwise approved by the Joint Planning Board, each Group Physician
Stockholder or Full-time Physician Employee shall agree that during the term of
his/her employment or contractor agreement with the Group (w) not to practice
radiological medicine other than at the Premises or such other location or
Practice Site(s) as approved by the Joint Planning Board; (x) to devote
substantially all of his or her professional time, effort and ability to the
Practice; (y) to request in writing and receive in writing prior approval from
the Joint Planning Board to engage in any outside medical activities; and (z)
to turn over to the Practice, to be included in Professional Revenues
attributed to the Practice, any income derived by such Group Physician
Stockholder or Full-time Physician Employee from any outside medical activity
or related source from the following medically-related activities: teaching,
consulting, medical research, inventions developed utilizing the Group's or the
Practice's time and material, testimony for litigation, and insurance
examinations.  The Group shall not materially amend, alter or otherwise change
any term or provision of any Stockholder Employment Agreement or Physician
Employee Employment Agreement relating to the foregoing covenants in this
Section 6.2 without the prior written consent of Administrator; notwithstanding
the foregoing, any such amendment, alteration or change shall not be
inconsistent with the terms or provisions of this Agreement.  Following
termination of this Agreement, the Group shall not amend, alter or otherwise
change any term or provision of the Restrictive Covenants, unless such
provisions are no longer in force and effect pursuant to the terms of the
applicable Stockholder Employment Agreement or Physician Employee Employment
Agreement at the time of termination of this Agreement.  In the event the
Purchase Assets are acquired by the Group pursuant to Article X, the obligation
of the Group to enforce Restrictive Covenants shall be limited to enforcement
of non-solicitation and nondisclosure of confidential/proprietary information
covenants.

         Section 6.3        Enforcement of Restrictive Covenants and Other
Provisions.  The Group shall enforce the Stockholder Employment Agreements and,
to the extent permitted under applicable law, the Physician Employee Employment
Agreements, including, without limitation, the Restrictive Covenants.  The
costs and expenses of such enforcement shall be included in Professional
Expenses and all damages and other amounts recovered thereby shall be included
in Professional Revenues.  In the event that, after a request by Administrator,
the Group does not pursue any remedy that may be available to it by reason of a
breach or default of the Restrictive Covenants or any other provision of the
Stockholder Employment Agreements and, to the extent permitted under applicable
law, the Physician Employee Employment Agreements, upon the request of





                                       35
<PAGE>   41
Administrator, the Group shall assign to Administrator such causes of action
and/or other rights it has related to such breach or default and shall
cooperate with and provide reasonable assistance to Administrator with respect
thereto; in which case, all costs and expenses incurred in connection therewith
shall be borne by Administrator and shall be included in Administrator
Expenses, and Administrator shall be entitled to all damages and other amounts
recovered thereby.  In the event the Purchase Assets are acquired by the Group
pursuant to Article X, the obligation of the Group to enforce Restrictive
Covenants shall be limited to enforcement of non-solicitation and nondisclosure
of confidential/proprietary information covenants.

         Section 6.4        Remedies.  Administrator and the Group acknowledge
and agree that a remedy at law for any breach or attempted breach of the
provisions of this Article VI shall be inadequate, and therefore, either party
shall be entitled to specific performance and injunctive or other equitable
relief in the event of any such breach or attempted breach, in addition to any
other rights or remedies available to either party at law or in equity.  Each
party hereto waives any requirement for the securing or posting of any bond in
connection with the obtaining of any such injunctive or other equitable relief.
If any provision of the Restrictive Covenants or this Article VI relating to
the restrictive period, scope of activity restricted and/or the territory
described therein shall be declared by a court of competent jurisdiction to
exceed the maximum time period, scope of activity restricted or geographical
area such court deems reasonable and enforceable under applicable law, the time
period, scope of activity restricted and/or area of restriction held reasonable
and enforceable by the court shall thereafter be the restrictive period, scope
of activity restricted and/or the geographical area applicable to such
provision of the Restrictive Covenants or this Article VI.  The invalidity or
non-enforceability of any provision of the Restrictive Covenants or this
Article VI in any respect shall not affect the validity or enforceability of
the remainder of the Restrictive Covenants or this Article VI or of any other
provisions of this Agreement.

         Section 6.5        Condition Precedent to Release of Obligations.  In
the event a Group Physician Stockholder or Full-time Physician Employee
terminates his/her employment agreement with the Group, the Group shall be
entitled to release (with the consent of Administrator in its sole and absolute
discretion) such Group Physician Stockholder or Full-time Physician Employee
from the restrictive covenants contained in Section 6.2, above.  In the event
the Group elects to release such Group Physician Stockholder or Full-time
Physician Employee, the Group hereby covenants that it shall obtain a formal
agreement between each Group Physician Stockholder or Full-time Physician
Employee, as the case may be, and Administrator which provides that, for a
period of two (2) years following termination of any employment agreement with
the Group, such Group Physician Stockholder or Full-time Physician





                                       36
<PAGE>   42
Employee agrees to (a) engage Administrator as the sole and exclusive manager
and administrator of the non-medical functions and services of said Group
Physician Stockholder's or Full-time Physician Employee's medical practice and
(b) pay to Administrator the identical amount [NY only] of revenues paid by the
Group to the Administrator attributable to such Group Physician Stockholder or
Full-time Physician Employee derived from such Group Physician Stockholder's or
Full-time Physician Employee's performance of professional medical services
within 15 miles of any Practice Site.

         Section 6.6        Service Area Rights and Obligations.

         (a)     Primary Service Area.  During the term of this Agreement and
within any Primary Service Area, Parent, Administrator or their Affiliates
shall not, without the prior written consent of the Group, (i) acquire or lease
the non-medical assets (through an asset acquisition, merger or other
consolidation or otherwise) of any Radiologist, group of Radiologists or
professional corporation or association (or other professional entity) whose
owners are Radiologists, (ii) acquire any imaging center where, within a
reasonable time period following such acquisition, the Group will not be
entitled to provide professional Radiology services for such imaging center, or
(iii) contract to provide management and administrative services similar to
those provided under this Agreement to any Radiologist, group of Radiologists
or professional corporation or association (or other professional entity) whose
owners are Radiologists.  Following a request for written consent by
Administrator, Parent or their Affiliates hereunder, the Group shall respond
upon the earlier of (i) within thirty (30) days from receipt of such request
and all other necessary information related thereto or (ii) one-half of the
time during which Administrator, Parent or their Affiliates must respond.  In
the event the Group, Parent, Administrator or their Affiliates acquire a
Professional Service Opportunity, the Group shall accept such Professional
Service Opportunity and shall perform any and all professional Radiology
services that are reasonably required at such location(s) in accordance with
the terms and provisions of this Agreement; provided (x) that the professional
reimbursement for such services is reasonable in relation to the overall market
environment and work effort required and (y) the Group shall not be required to
employ any Radiologist previously associated with such Professional Service
Opportunity.

         (b)     Secondary Service Area.  During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity.  Within the earlier
of (i) thirty





                                       37
<PAGE>   43
(30) days or (ii) one-half of the time during which the Administrator, Parent or
their Affiliates must respond to an offer described in the Administrator's
Notice, the Group shall deliver to Administrator a written notice stating
whether or not the Group elects to accept or reject the New Professional
Service Opportunity which election shall be binding on the Group.  If the Group
does not elect to exercise the right or fails to provide the notice to
Administrator within the time frame herein provided, Administrator shall be
released from the right of first offer with respect to that particular New
Professional Service Opportunity.  Prior to consummating any asset acquisition,
merger or other consolidation of any Radiologist, group of Radiologists, or
professional corporation or association (or other professional entity) whose
owners are Radiologists within any Secondary Service Area, Administrator shall
first consult with the Joint Planning Board.

         (c)     Determination of Primary and Secondary Service Area.  The
existence and location of each of the Group's Primary Service Areas and
Secondary Service Areas shall be determined each time the Group, Parent,
Administrator or their Affiliates propose an acquisition, management
relationship, Professional Service Opportunity or New Professional Service
Opportunity as contemplated in subsections (a) and (b) above.

         (d)     Dispute Resolution.  Any disputes regarding the interpretation
of the provisions of this Section 6.6 shall be referred to and decided by the
Joint Planning Board as provided in Section 5.3 of this Agreement.

         (e)     Definitions.  The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

                 "New Professional Service Opportunity" shall mean a
Professional Service Opportunity pursuant to which the Group or any other
member of an APPI Group managed by Parent, Administrator or their Affiliates is
not currently providing professional Radiology services.

                 "Primary Service Area" shall mean that area within a five (5)
mile radius from any imaging center owned, operated or managed by
Administrator, Parent or their Affiliates for which the Group provides
professional Radiology services or any hospital at which on-site professional
Radiology services are then provided by Physician Employee(s) or Physician
Extender Employee(s) of the Group.

                 "Professional Service Opportunity" shall mean any opportunity
to perform professional Radiology services for any hospital, hospital system or
imaging center under a formal agreement with such entity.

                 "Radiologist" shall mean and include both radiologists and
radiation oncologists.





                                       38
<PAGE>   44
                 "Radiology" shall mean and include diagnostic imaging,
interventional radiology and radiation oncology services.

                 "Secondary Service Area" shall mean (i) during the 12-month
period following the Acquisition Effective Date, that area which extends ten
(10) miles beyond the boundary of any Primary Service Area and (ii) during the
remaining term of this Agreement, that area which extends five (5) miles beyond
the boundary of any Primary Service Area.

         Section 6.7        Survival of Certain Covenants.  If this Agreement
is terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section
6.2 and Section 6.3 shall survive such termination if the actions or events
giving rise to a breach of the Restrictive Covenants or other provisions
occurred prior to such termination.  If the Agreement is terminated pursuant to
the preceding sentence, all of the provisions of Section 6.1 shall survive.
However, regardless of the reason for termination, or upon expiration of this
Agreement, the provisions of Section 6.1(d),(e),(f) and (g) shall survive such
termination or expiration indefinitely unless otherwise expressly limited as to
a period of time.

         Section 6.8        Definition.  The term "Full-time Physician
Employee" as used in Sections 6.2 and 6.5 of this Article VI only, shall mean a
Full-time Physician Employee who shall have been employed by the Group for two
(2) years; provided, that such Full-time Physician Employee shall enter into a
written agreement at the commencement of the later of (i) his/her employment or
(ii) the Acquisition, which includes the provisions set forth in Sections 6.2
and 6.5, above, and acknowledges his/her understanding that such provisions
will be enforceable against such Full-time Physician Employee following such
two (2) year period.  Notwithstanding the foregoing, the Group shall be
entitled to apply to the Joint Planning Board for the purpose of requesting
that a particular Full-time Physician Employee not be required to execute an
employment agreement that contains the provisions contained in Sections 6.2 and
6.5, which such release by Administrator shall not be unreasonably withheld.

                                  ARTICLE VII

                      Financial and Security Arrangements

         Section 7.1        Service Fee.  The Group and Administrator agree
that the compensation set forth in this Article VII is being paid to
Administrator in consideration of the services provided and the substantial
commitment and effort made by Administrator hereunder and that such fees have
been negotiated at arms' length and are fair, reasonable and consistent with
fair market value.  Administrator shall be paid the service fee (the "Service
Fee") as set forth on Exhibit 7.1 hereto.  Payment of the Service Fee is not





                                       39
<PAGE>   45
intended to and shall not be interpreted or implied as permitting Administrator
to share in the Group's fees for medical services but is acknowledged as the
negotiated fair market value compensation to Administrator considering the
scope of services and the business risks assumed by Administrator.

         Section 7.2        Payments.  Except as otherwise set forth on Exhibit
7.1 hereto, the amounts to be paid to Administrator under this Article VII
shall be calculated by Administrator on the accrual basis of accounting and
shall be payable monthly.  Payments due for any Service Fee shall be made by
the Group each calendar month as provided herein and shall be paid on the 15th
day following the end of such month (or the first preceding day that is a
business day if the 15th day is not a business day) (a "Payment Date").  Except
as otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates
based upon available information for such month, and adjustments to the
estimated payments shall be made to reconcile final amounts due under Section
7.1 on the next Payment Date.

         Section 7.3        Advances.  The Group shall be entitled to an
advance from Administrator of such additional sums, over and above the Group's
right to the amounts otherwise set forth in this Article VII, as shall be
required by the Group to pay Practice Expenses (excluding Technical Expenses)
consistent with the annual capital and operating budgets of the Practice
(prepared as provided in Section 3.5 hereof), the Service Fee as provided in
Exhibit 7.1 hereto and Excluded Practice Expenses at the discretion of
Administrator.  Any amounts advanced to the Group pursuant to this Section 7.3
shall be repaid by the Group in such priority as set forth in Section 7.6 below
and shall bear interest at Parent's then available, borrowing rate offered by
Administrator's or Parent's senior lender (which rate shall be charged
consistently to each physician group who enters into a Service Agreement with
Administrator) until all such amounts of principal and interest are repaid to
Administrator as provided herein.  Notwithstanding the foregoing, no interest
shall accrue or be paid by the Group for amounts advanced to the Group pursuant
to this Section 7.3 during the forty-five (45)-day period immediately following
the Acquisition Effective Date.

         Section 7.4        Security Agreement.  In order to enforce its rights
granted hereunder and subject to applicable law, the Group shall execute a
Security Agreement in substantially the form attached hereto as Exhibit 7.4
(the "Security Agreement"), which Security Agreement grants a security interest
in all of the Group's accounts receivable (as more fully described in the
Security Agreement) to Administrator.  In addition, the Group shall cooperate
with Administrator and execute all necessary documents in connection with the
pledge of such accounts receivable to Administrator or at Administrator's
option, its lenders.





                                       40
<PAGE>   46
         Section 7.5        Adjustment of Fees.  In addition to the adjustments
provided for in Section 7.2, Service Fees payable by Group pursuant to this
Article VII shall be adjusted as appropriate upon agreement of the parties upon
the divestiture or acquisition by the Group of, or affiliation with, a
radiology or diagnostic practice group.  Whether or not Parent capital stock or
funds are utilized to fund the acquisition or affiliation, the Service Fee and
other related provisions of this Agreement shall be adjusted as agreed upon by
the parties on a case by case basis.  Under either acquisition or affiliation
model, the precise adjustment to the Service Fee and to other related
provisions of this Agreement shall be a joint decision of the parties, shall be
memorialized in a written amendment to this Agreement, and shall be based upon
the methodology used to generally determine Services Fees hereunder.

         Section 7.6        Priority of Payments.  Administrator shall
administer and make disbursements from amounts deposited into the Deposit
Account or transferred from the Deposit Account to pay (including, without
limitation the making of advances as provided in Section 7.3) the Practice
Expenses and Excluded Practice Expenses as the same become due and payable, and
for which the Group shall remain responsible; provided, however, that if
Technical Expenses exceed Technical Revenues, then the amount by which
Technical Expenses exceed Technical Revenues shall be excluded for purposes of
the priority of payments set forth below and the Group shall not be responsible
for such amount.  In performing its obligations pursuant to Article III, on the
fifteenth (15th) day following the end of each calendar month, Administrator
shall apply an amount equal to the aggregate face amount of the prior month's
accounts receivables, less contractual adjustments and estimated allowances for
bad debt as determined in accordance with Section 3.2(e), in the following
order of priority:

         (a)     payment of all accrued Practice Expenses for the prior month
                 (subject to the proviso in the preceding sentence);

         (b)     payment of the accrued Service Fee for the prior month;

         (c)     payment of the outstanding balance of all amounts advanced to
                 the Group through the end of the prior month, and applicable
                 interest thereon (as contemplated in Section 7.3); and

         (d)     payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account
on the fifteenth (15th) day following the end of each calendar month (or the
first preceding day if the 15th day is not a business day).

<PAGE>   47
                                  ARTICLE VIII

                                    Records

         Section 8.1        Records.  All records relating in any way to the
operation of the Practice (other than Group Records) shall, subject to the
obligations of the Practice to maintain patient medical records pursuant to
Section 3.2(g), at all times be the property of Administrator as set forth in
Section 3.2(g).  During the term of this Agreement, and for a reasonable time
thereafter, the Group or its agents shall have reasonable access during normal
business hours to the Group's and Administrator's personnel and financial
records relating to the Practice, including, but not limited to, records of
collections, expenses and disbursements as kept by Administrator in performing
Administrator's obligations under this Agreement, and the Group may copy any or
all such records.

                                   ARTICLE IX

                         Insurance and Indemnification

         Section 9.1        Insurance to be Maintained by the Group.

         (a)     During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties.  Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group.  All comprehensive professional
medical/malpractice liability insurance premiums and deductibles shall be
included in Practice Expenses; provided, that if the Group elects to maintain
coverage that exceeds minimum requirements, such additional premiums shall be
included in Excluded Practice Expenses.  All costs, expenses and liabilities
incurred by the Group in excess of the limits of such policies identified in
the preceding sentence shall be included in Excluded Practice Expenses.
Administrator, Parent or their Affiliates shall attempt to secure excess
liability for the types of coverages contemplated by this Section 9.1(a).  If
successful, the Group shall have the opportunity to purchase at Administrator's
cost, as an Excluded Practice Expense, such coverage to the extent permitted by
the then-applicable restrictions set forth in such policy.

         (b)     The Group, Administrator and Parent each waives any right one
may have against the other, to the extent allowed by the waiving party's
insurance coverage, on account of any loss or damage occasioned to any party by
another party, their respective





                                       42
<PAGE>   48
real and personal property, the Premises or its contents, arising from any risk
generally covered by fire and extended coverage insurance or from vandalism or
malicious mischief; and the parties, on behalf of their respective insurance
companies, waive any right to subrogation, except when such loss or damage is
due to the gross negligence or willful misconduct of the other party.

         Section 9.2        Insurance to be Maintained by Administrator.
During the term of this Agreement, Administrator will provide and maintain (i)
as a Technical Expense, comprehensive professional medical/malpractice
liability insurance for all applicable employees of Administrator and (ii) as a
Practice Expense, comprehensive general liability and property insurance
covering the Practice's premises (including, without limitation, the Premises),
personal property and operations with such limits and coverages as a reasonable
business person under similar circumstances would maintain.  All costs,
expenses and liabilities incurred by Administrator in excess of the limits of
such policies identified in subsections (i) and (ii) hereof shall be included
in Administrator Expenses.

         Section 9.3        Continuing Liability Insurance Coverage.  The Group
shall obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a
"tail policy" or a "prior acts policy," with the same limits and deductibles as
the insurance coverage provided pursuant to Section 9.1 upon the termination of
such physician's relationship with the Group for any reason, unless such
physician was covered with an occurrence-based policy while employed or
retained by the Group.  In the event that the Group, any Physician Employee or
Physician Extender Employees fails to obtain such continuing liability
insurance coverage, Administrator may do so.  The cost of such continuing
liability insurance coverage shall be included in Practice Expenses unless such
cost is borne by the Physician Employee.

         Section 9.4        Additional Insureds.  The Group and Administrator
agree to use their reasonable efforts to have each other named as an additional
insured on the other's respective professional liability insurance programs.
The additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5        Indemnification.

         (a)     By the Group.  The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred,





                                       43
<PAGE>   49
that are caused or asserted to have been caused, directly or indirectly, by or
as a result of the performance of medical services or the performance of any
intentional acts, negligent acts or omissions by the Group and/or its
shareholders, employees and/or subcontractors (other than Administrator,
Parent, Affiliates or their employees, officers, directors, agents, attorneys
and consultants) during the term of this Agreement.  Provided, however, that in
the event an indemnification obligation under the preceding sentence arises as
of the result of any act or omission of a person who is an officer, shareholder
or other equity holder, director, employee, agent, attorney or consultant of
Administrator, Parent or any of their Affiliates (other than in connection with
the activities of the Joint Planning Board), such person shall not be entitled
to indemnification in connection therewith and any other adjustment as is
equitable shall be made to the Group's indemnification obligation arising
thereby.

         (b)     By the Administrator.  Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or
incurred, that are caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts or omissions by Administrator, Parent or Affiliates and/or any
of their respective shareholders, employees and/or subcontractors (other than
the Group or its employees) during the term of this Agreement.  Provided,
however that in the event an indemnification obligation under the preceding
sentence arises as a result of any act or omission of a person who is an
officer, shareholder or other equity holder, director, employee, agent,
attorney or consultant of the Group (other than in connection with the
activities of the Joint Planning Board), such person shall not be entitled to
indemnification in connection therewith and any other adjustment as is
equitable shall be made to Administrator's or Parent's indemnification
obligation arising thereby.

                                   ARTICLE X

                              Term and Termination

         Section 10.1       Term of Agreement.  This Agreement shall commence
on the date hereof and shall expire on the 40th anniversary hereof unless
earlier terminated pursuant to the terms of either Section 10.3 or Section 10.4
or automatically extended pursuant to the terms of Section 10.2.

         Section 10.2       Extended Term.  Unless earlier terminated as
provided for in either Section 10.3 or Section 10.4, the term of





                                       44
<PAGE>   50
this Agreement shall be automatically extended for additional terms of five (5)
years each, unless either party delivers to the other party, not less than
twelve (12) months nor earlier than fifteen (15) months prior to the expiration
of the preceding term, written notice of such party's intention not to extend
the term of this Agreement.

         Section 10.3       Termination by the Group.  The Group may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a)     Administrator or Parent shall admit in writing its inability
to generally pay its debts when due, apply for or consent to the appointment of
a receiver, trustee or liquidator of all or substantially all of its assets,
file a petition in bankruptcy or make an assignment for the benefit of
creditors, or upon other action taken or suffered by Administrator or Parent,
voluntarily or involuntarily, under any federal or state law for the benefit of
creditors, except for the filing of a petition in involuntary bankruptcy
against Administrator or Parent which is dismissed within ninety (90) days
thereafter.

         (b)     Administrator or Parent shall default in the performance of
any material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group.  The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not the
obligation, to cure any Material Adminstrator Default.  Notwithstanding
anything to the contrary in this Agreement, following receipt by Administrator
of the notice of a Material Administrator Default and until such Material
Administrator Default shall be cured, the Group may take such action as may be
reasonably required to cover such Material Administrator Default so as to
maintain for the Group the same level of service as before the Material
Administrator Default, without prejudicing in any way the Group's other rights
and remedies, and may offset all of its costs from the amounts which may
otherwise be due to Administrator under this Agreement.

         (c)     An independent law firm with nationally recognized expertise
in health care law and acceptable to the parties hereto renders an opinion to
the parties hereto that (i) a material provision of this Agreement is in
violation of applicable law or any court or regulatory agency enters an order
finding a material provision of this Agreement is in violation of applicable
law and





                                       45
<PAGE>   51
(ii) this Agreement can not be amended pursuant to Section 11.6 hereof to cure
such violation.

         Section 10.4       Termination by Administrator.  Administrator may,
in its sole discretion, terminate this Agreement by giving written notice
thereof to the Group (after the giving of any required notices and the
expiration of any applicable waiting periods set forth below) upon the
occurrence of any of the following events:

         (a)     The Group shall default in the performance of any material
duty or material obligation imposed upon it by this Agreement (a "Material
Group Default") and (i) the Group fails to deliver to Administrator within
thirty (30) days after written notice of such Material Group Default has been
given to Group a written plan (reasonably acceptable to Administrator)
detailing the methods and procedures that the Group shall utilize to cure such
Material Group Default, (ii) the Group has delivered a plan but has failed to
utilize its best efforts to cure such Material Group Default within sixty (60)
days after written notice thereof has been given to the Group by Administrator
or (iii) the Group has delivered the plan but, after utilizing its best
efforts, is unable to cure such Material Group Default within ninety (90) days
after written notice thereof has been given to the Group by Administrator.  The
term "Material Group Default" for purposes of this Section 10.4 shall include,
but not be limited to, (A) the Group's admission in writing of its inability to
generally pay its debts when due, application for or consent to the appointment
of a receiver, trustee or liquidator of all or substantially all of its assets,
filing of a petition in bankruptcy or making an assignment for the benefit of
creditors, or upon other action taken or suffered by the Group, voluntarily or
involuntarily, under any federal or state law for the benefit of debtors,
except for the filing of a petition in involuntary bankruptcy against the Group
which is dismissed within ninety (90) days thereafter or (B) the Group or any
Physician Employee (1) fails to adhere to any compliance plan, policy, or
manual as described in Section 4.6 hereof that has been approved by the Group
and made applicable to all shareholders and employees of the Group, or (2)
engages in any conduct or is formally accused of conduct for which the Group's
ability or license, or a Physician Employee's license to practice medicine
reasonably would be expected to be subject to revocation or suspension, whether
or not actually revoked or suspended, or (3) is notified in writing of any
adverse action by any state or federal department or agency that has the effect
of either excluding that individual from participating in or from receiving
reimbursement under any program funded by the federal government or by any
state government, notwithstanding any available post-sanction remedies, or (4)
is otherwise disciplined by any licensing, regulatory or professional entity or
institution, the result of any of which event does or is reasonably expected to
materially adversely affect the Practice, the result of any of which event
described in subparagraphs (1) through (4) above, in





                                       46
<PAGE>   52
the absence of termination of a Physician Employee or a Physician Extender
Employee or other action of the Group to monitor and cure such act or conduct
by such employee, does or reasonably would be expected to materially and
adversely affect the Practice or the Group.  Notwithstanding anything to the
contrary in this Agreement, following receipt by the Group of the notice of a
Material Group Default, and until such Material Group Default shall be cured,
the Administrator may take such action as may be reasonably required to cover
such Material Group Default so as to maintain for the Administrator the same
level of service at the Premises as before the Material Group Default, without
prejudicing in any way Administrator other rights and remedies, and may offset
all of its costs of cover from amounts which may otherwise due to the Group
under this Agreement.

         (b)     An independent law firm with nationally recognized expertise
in health care law and acceptable to the parties hereto renders an opinion to
the parties hereto that (i) a material provision of this Agreement is in
violation of applicable law or any court or regulatory agency enters an order
finding a material provision of this Agreement is in violation of applicable
law and (ii) this Agreement can not be amended pursuant to Section 11.6 hereof
to cure such violation.

         (c)     At any time during the five-year period following the
Acquisition Effective Date if more than thirty-three and one-third percent
(33 1/3%) of the total number of Group Physician Stockholders and Full-time
Physician Employees retained or employed by the Group at the time of the
Acquisition Effective Date are no longer employed or retained by the Group for
reasons other than (i) death, (ii) permanent disability, (iii) loss of a
hospital contract or privileges for reasons other than voluntary resignation by
the Group or a failure to renew or a failure to respond to a reasonable proposal
to extend the term of such contract or (iv) voluntary closing of facilities by
Administrator.  For purposes of this Section 10.4(c), if Parent and/or
Administrator are notified in writing by the Group at or prior to the
Acquisition Effective Date of any Physician Employee [or Physician Extender
Employee] that intends to retire prior to expiration of such five-year period,
then such Physician Employee or Physician Extender Employee shall not be counted
for purposes of determining the above percentage.

         Section 10.5       Effective Date of Termination.  Any termination of
this Agreement shall be effective (the "Termination Date") as follows:

         (a)     Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         (b)     Upon the expiration of this Agreement pursuant to Sections
10.1 or 10.2.

         Section 10.6       Purchase of Assets.  Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the
option to require Administrator and/or Parent to sell to the Group, and if the
Group is the defaulting party, Administrator and/or Parent shall have the
option to require the Group to purchase from Administrator and/or Parent, the
Purchase Assets and assume the Practice Related Liabilities below:

         (a)     Purchase Assets.  The Group shall purchase, free and clear of
all liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or their
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's and/or their Affiliates' accounting and financial records (the
"Purchase Assets"), including, but not limited to, without duplication, (i) all
equipment, furniture, fixtures, furnishings, inventory, supplies, improvements,
additions and leasehold improvements utilized by the Practice, (ii) any real
estate owned by Administrator, Parent or Affiliates that is occupied by or used
primarily for the benefit of the Practice, (iii) all unamortized intangible
assets (including, without limitation, goodwill) set forth on the financial
statements of Administrator, Parent or their Affiliates used solely in
connection with the Practice or otherwise resulting from the Acquisition;
provided, however, that no amortization with respect to the goodwill associated
with the Acquisition shall be set forth on such financial statements, (iv) all
Confidential and Proprietary Information that relates solely to the Practice,
and (v) all other assets that would be set forth on a balance sheet of
Administrator, Parent or their Affiliates prepared as of the date of the
Purchase Closing relating primarily to the Practice.

         (b)     Practice Related Liabilities.  The Group shall assume all of
Administrator's and its Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c)     Purchase Price.  The Purchase Price shall be the lesser of (i)
Fair Market Value of the Purchase Assets subject to the assumption of the
Practice Related Liabilities or (ii) the value of the Actual Consideration
(defined below)(alternatively, the "Purchase Price"); provided, however, the
Purchase Price shall not be less than the net book value of the Purchase Assets
at the Termination Date.  The Purchase Price shall be paid pursuant to Section
10.7.  For purposes of this subparagraph (c), the term "Actual Consideration"
shall mean (i) cash consideration paid to





                                       48
<PAGE>   54
the Group pursuant to the Acquisition Agreement and (2) an amount equal to the
number of shares of Parent Common Stock (as adjusted for stock splits, stock
dividends, recapitalizations, reorganizations, or any similar transaction
whereby the Parent Common Stock is increased or decreased or exchanged for a
different number or kind of securities) issued pursuant to the Acquisition
Agreement multiplied by the fair market value of Parent Common Stock
immediately prior to the time that a Termination Notice is provided pursuant to
Section 10.7.  The Purchase Price shall be appropriately adjusted to offset and
account for any monetary obligations of the Group or Administrator owing to the
other as provided herein.

         (d)     Exercise of Option.

                 (i)        The Group.  Upon a termination of this Agreement,
the Group shall be entitled to exercise its option to require Administrator,
Parent or their Affiliates to sell the Purchase Assets and shall assume the
Practice Related Liabilities pursuant to this Section 10.6 at any time (unless
this Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                 (ii)       Administrator.  Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

         (e)     Notice.  Each party shall exercise its option under this
Section 10.6 by giving written notice thereof in the Termination Notice, if
applicable, or prior to ninety (90) days before the Termination Date if this
Agreement expires pursuant to Sections 10.1 or 10.2.

         Section 10.7       Terms of Purchase.  The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice.  The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses.  Subject to the conditions set forth
below, at the Purchase Closing, Administrator and/or its Affiliates, as the
case may be, shall transfer and assign the Purchase Assets to the Group, and in
consideration therefor, the Group shall (a) pay to Administrator, Parent and/or
their Affiliates an amount in cash or, at the option of the Group (subject to
the conditions set forth below), Parent Common Stock (valued pursuant to
Section 10.6(c) hereof), or some





                                       49
<PAGE>   55
combination of cash and Parent Common Stock equal to the Purchase Price and (b)
assume the Practice Related Liabilities.  The structure of the transaction set
forth in this Section 10.7 shall, if possible, be structured as a tax-free
transaction under applicable law.  Each party shall execute such documents or
instruments as are reasonably necessary, in the opinion of each party and its
counsel, to effect the foregoing transaction.  The Group shall, and shall use
its best efforts to cause each shareholder of the Group to, execute such
documents or instruments as may be necessary to cause the Group to assume the
Practice Related Liabilities and to release Administrator, Parent and/or their
Affiliates, as the case may be, from any liability or obligation with respect
thereto.  In the event the Group desires to pay all or a portion of the
Purchase Price in shares of Parent Common Stock, such transaction shall be
subject to the satisfaction of each of the following conditions:

         (a)     The holders of such shares of Parent Common Stock shall
transfer to Administrator, Parent and/or their Affiliates good, valid and
marketable title to the shares of Parent Common Stock, free and clear of all
adverse claims, security interests, liens, claims, proxies, options,
stockholders' agreements and encumbrances (not including any applicable
securities restrictions and lock-up arrangements with the Parent or any
underwriter); and

         (b)     The holders of such shares of Parent Common Stock shall make
such representations and warranties as to title to the stock, absences of
security interests, liens, claims, proxies, options, stockholders' agreements
and other encumbrances and other matters as reasonably requested by
Administrator, Parent and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain financing for such acquisition but is unable to
obtain such financing and (iii) there is either a Material Administrator
Default pursuant to Section 10.3(a) or (c) or a Material Group Default pursuant
to Section 10.4(b) triggering a sale of the Purchase Assets, the Group shall be
entitled to obtain financing from Administrator, Parent and/or their
Affiliates, but only for the difference between the Fair Market Value of the
Purchase Assets and the net book value of the Purchase Assets.  The terms of
such financing shall be for a five (5) year period at an interest rate equal to
the prime rate (as published in the Wall Street Journal) plus four percent (4%)
or such lesser rate as is required to be in conformance with all applicable
state and federal law.  In the event the Group is entitled to obtain financing
from Administrator, Parent and/or their Affiliates the Group shall execute and
deliver to Administrator, Parent and/or their Affiliates all such documentation
necessary and appropriate to effectuate the financing transaction including,
without limitation, a secured promissory note, security agreement and financing
statements and such





                                       50
<PAGE>   56
documentation shall contain such representations, warranties and conditions
customary to a secured transaction of this size.

         Section 10.8       Exception to Purchase.  Notwithstanding anything
contained herein to the contrary, Administrator, Parent and/or their Affiliates
shall not be obligated to sell the Purchase Assets to the Group as provided in
Section 10.6(d)(i) above if the Group is not able to pay the Purchase Price
pursuant to the terms set forth above and assume the Practice Related
Liabilities at the Purchase Closing.  In such event, the Group shall surrender
the Purchase Assets to Administrator, Parent and/or their Affiliates as of the
Purchase Closing.  If the Practice fails to so surrender the Purchase Assets,
Administrator, Parent and/or their Affiliates may, if permitted by applicable
law, without prejudice to any other remedy which it may have hereunder or
otherwise, enter the Premises and take possession of the Purchase Assets and
expel or remove the Group and any other person who may be occupying the
Premises or any part thereof, by force if necessary, without being liable for
prosecution or any claim for damages therefor.

         Section 10.9       Effect Upon Termination.  Upon the Termination
Date, except as provided below, this Agreement shall terminate and shall be of
no further force and effect and all further obligations of Administrator,
Parent, and/or their Affiliates and the Group under this Agreement shall
terminate without further liability of the Administrator, Parent and/or their
Affiliates to the Group or the Group to the Administrator, Parent and/or their
Affiliates (including, without limitation, any liability for loss of
anticipated profits over the remaining term of this Agreement or from a sale of
the Purchase Assets pursuant to this Article X at less than Fair Market Value),
except with respect to the obligations set forth below.  The foregoing to the
contrary notwithstanding:

         (a)     Administrator, Parent and/or their Affiliates shall use their
best efforts to cooperate with the Group for the appropriate transfer of
management services.

         (b)     Each party hereto shall provide the other party with
reasonable access to books and records owned by it to permit such requesting
party to satisfy reporting and contractual obligations which may be required of
it.

         (c)     Any other amounts due and owing but unpaid to either
Administrator, Parent and/or their Affiliates or the Group as of the
Termination Date shall be paid promptly by the appropriate party.

         (d)     Any and all covenants and obligations of either party hereto
which by their terms or by reasonable implication are to be performed, in whole
or in part, after the termination of this Agreement, shall survive such
termination, including, without limitation, the obligations of the parties
pursuant to the





                                       51
<PAGE>   57
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.

                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1       Informal Dispute Resolution.  In the event of any
claim, controversy, dispute or disagreement between or among the parties hereto
which is not subject to the dispute resolution methodology set forth in Article
V hereof, the parties hereto agree that such other claims, controversies,
disputes or disagreements shall be presented to the Joint Planning Board for
hearing and resolution.  In the event the Joint Planning Board is unable to
resolve such matter within a reasonable period following presentation to the
Joint Planning Board, such matter shall be presented to either (a) the Board of
Directors of Parent or (b) a committee designated by the Board of Directors of
Parent which contains at least one (1) physician member.  The Board of
Directors of Parent or such committee shall meet within thirty (30) days to
attempt to resolve such claim, controversy, dispute or disagreement.

         Section 11.2       Arbitration.  If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V
hereof, cannot be resolved by the informal means set forth in Section 11.1, the
parties hereto agree that any such claim, controversy, dispute or disagreement
between or among any of the parties shall be governed exclusively by the terms
and provisions of this Article XI; provided, however, that within ten (10) days
from the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means set forth in Section 11.1 and prior to
commencing an arbitration procedure pursuant to this Article XI, the parties
shall meet to discuss and consider other alternative dispute resolution
procedures other than arbitration, provided, however that if the parties hereto
agree to an alternative to arbitration they may agree to an alternative set of
rules, including rules of evidence and procedure.  If at any time prior to the
rendering of the decision by the arbitrator (or pursuant to such other
alternative dispute resolution procedure) as contemplated in this Article XI to
the extent a party makes a written offer to the other party proposing a
settlement of the matter(s) at issue and such offer is rejected, then the party
rejecting such offer shall be obligated to pay the costs and expenses
(excluding the amount of the award granted under the decision) of the party
that offered the settlement from the date such offer was received by such other
party if the decision is for a dollar amount that is less than the amount of
such offer to settle.  Notwithstanding the foregoing, the terms and provisions
of this Article XI shall not preclude any party hereto from seeking,





                                       52
<PAGE>   58
or a court of competent jurisdiction from granting, a temporary restraining
order, temporary injunction or other equitable relief for any breach of (i) any
noncompetition or confidentiality covenant or (ii) any duty, obligation,
covenant, representation or warranty, the breach of which may cause irreparable
harm or damage.

         Section 11.3       Arbitrators.  In the event there is a claim,
controversy, dispute or disagreement among Administrator and the Group arising
out of or relating to this Agreement (including any claim based on or arising
from an alleged tort) and the parties hereto have not reached agreement
regarding an alternative to arbitration, the parties agree to select within 30
days of notice by a party to the other of its desire to seek arbitration under
this Article XI one arbitrator mutually acceptable to Administrator and the
Group to hear and decide all such claims under this Article XI.  If such matter
or action involves health-care issues, then the arbitrator shall have such
qualifications as would satisfy the requirements of the National Health Lawyers
Association Alternative Dispute Resolution Service.  Each of the arbitrators
proposed shall be impartial and independent of all parties.  If the parties
cannot agree on the selection of an arbitrator within said 30-day period, then
any party may in writing request the judge of the United States District Court
for the Western District of New York senior in term of service to appoint the
arbitrator and, subject to this Article XI, such arbitrator shall hear all
arbitration matters arising under this Article XI.

         Section 11.4       Applicable Rules.

         (a)     Each arbitration hearing shall be held at a place in Monroe
County, New York acceptable to the arbitrator.  The arbitration shall be
conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof.  The decision of the arbitrator shall be reduced to writing and shall
be binding on the parties and such decision shall contain a concise statement
of the reasons in support of such decision.  Judgment upon the award(s)
rendered by the arbitrator may be entered and execution had in any court of
competent jurisdiction or application may be made to such court for a judicial
acceptance of the award and an order of enforcement.  The charges and expenses
of the arbitrator shall be shared equally by the parties to the hearing.

         (b)     The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI.
In fulfilling his duties with respect to determining the amount of any loss,
the arbitrator may consider such matters as, in the opinion of the arbitrator,
are necessary or helpful to make a proper valuation.  The arbitrator may
consult with and engage disinterested third parties to advise the arbitrator.
The arbitrator shall not add any interest factor reflecting the time value of
money to the amount of any loss and shall not award any punitive damages.





                                       53
<PAGE>   59
         (c)     If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior
judge (or such judge's successor) in the event the parties cannot agree, shall
select a replacement arbitrator.  The procedure set forth in this Article XI
for selecting the arbitrator shall be followed from time to time as necessary.

         (d)     As to any determination of the amount of any loss, or as to
the resolution of any other claim, controversy, dispute or disagreement, that
under the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e)     All privileges under New York and federal law, including
attorney-client and work-product privileges, shall be preserved and protected
to the same extent that such privileges would be protected in a federal court
proceeding applying New York law.

                                  ARTICLE XII

                               General Provisions

         Section 12.1       Assignment.

         (a)     Administrator shall have the right to assign its rights
hereunder to Parent or any direct or indirect wholly-owned subsidiary of
Administrator or Parent (that remains a wholly-owned subsidiary of
Administrator or Parent) or to a financial institution as collateral security
for the indebtedness of Parent, Administrator or their Affiliates without the
consent of the Group.  No assignment under subsection (a) shall relieve
Administrator or Parent of their obligations hereunder without the consent of
the Group.

         (b)     Administrator, Parent and their Affiliates shall provide
notice to the Group of Administrator's intent (i) to assign this Agreement
(other than as permitted in Section 12.1(a) herein), (ii) sell all or
substantially all of the assets of Administrator or (iii) effectuate a
consolidation, merger or sale of a majority of the capital stock of
Administrator as soon as practicable following a decision by the Parent's and
Administrator's respective boards of directors to seek such assignment or sale.
The assignment of this Agreement (other than as permitted in Section 12.1(a)),
the sale of all or substantially all of the assets of Administrator by Parent
or a consolidation, merger or sale of a majority of the capital stock of
Administrator shall not be permitted unless Administrator shall give written
notice to the Group stating the party who made the offer and specifying the
purchase price offered (the "Notice").  The Group shall have the option to
repurchase the Purchase Assets on the same terms and conditions set forth in
the Notice.  In the event the Group fails to provide written notice to
Administrator of its intent to exercise its option to repurchase the Purchase
Assets pursuant to this Section 12.1 within the earlier of (i) thirty (30) days
or (ii) one-half of the time during which Administrator, Parent or their
Affiliates must respond to an offer following the Group's receipt of the
Notice, the option contained in this Section 12.1 shall be deemed null and void
and of no further force and effect, and Administrator shall be free to assign
the Agreement, sell all or substantially all of the assets of Administrator or
sell or transfer all of the capital stock Administrator without the consent of
the Group.  No assignment under this subsection (b) shall relieve Administrator
or Parent of their obligations hereunder without the consent of the Group.

         Section 12.2       Amendments.  This Agreement shall not be modified
or amended except by a written document executed by all parties to this
Agreement, and such written modification(s) or amendment(s) shall be attached
hereto.

         Section 12.3       Waiver of Provisions.  Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto.  The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 12.4       Additional Documents.  Each of the parties hereto
agrees to execute any document or documents that may be reasonably requested
from time to time by the other party to implement or complete such party's
obligations pursuant to this Agreement.

         Section 12.5       Attorneys' Fees.  If legal action is commenced by
either party to enforce or defend its rights under this Agreement, the
prevailing party in such action shall be entitled to recover all reasonable
attorneys' fees, costs and expenses including, but not limited to, attorney's
fees, costs and expenses for trial, appellate proceedings and negotiations, in
addition to any other relief granted.

         Section 12.6       Contract Modifications for Prospective Legal
Events.  In the event any state or federal laws or regulations, now existing or
enacted or promulgated after the date hereof, are interpreted by judicial
decision, a regulatory agency or independent legal counsel in such a manner as
to indicate that this Agreement or any provision hereof may be in violation of
such laws or regulations, the Group and Administrator shall amend this
Agreement as necessary to preserve the underlying economic and financial
arrangements between the Group and Administrator and without substantial
economic detriment to either party.  If this Agreement cannot be so amended,
the terms of Section 10.3(c) and 10.4(b) shall apply.  To the extent any act or
service required of Administrator in this Agreement should be construed or
deemed, by any governmental authority, agency or court to constitute the
practice of medicine, the performance of said act or service by Administrator
shall be deemed waived and forever unenforceable and the provisions of this
Section 12.6 shall be applicable.  Neither party shall claim or assert
illegality as a defense to the enforcement of this Agreement or any provision
hereof; instead, any such purported illegality shall be resolved pursuant to
the terms of this Section 12.6 and Section 12.9.

         Section 12.7       Parties In Interest; No Third Party Beneficiaries.
Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto.
Except as provided in Section 6.1(g), neither this Agreement nor any other
agreement contemplated hereby shall be deemed to confer upon any person not a
party hereto or thereto any rights or remedies hereunder or thereunder.

         Section 12.8       Entire Agreement.  This Agreement and the
agreements contemplated hereby or delivered in connection herewith constitute
the entire agreement of the parties regarding the subject matter hereof, and
supersede all prior agreements and understandings, both written and oral, among
the parties, or any of them, with respect to the subject matter hereof.

         Section 12.9       Severability.  If any provision of this Agreement
is held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 12.10      Governing Law.  THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULE GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

         Section 12.11      No Waiver; Remedies Cumulative.  No party hereto
shall by any act (except by written instrument pursuant to Section 12.3 hereof),
delay, indulgence, omission or otherwise be deemed to have waived any right or
remedy hereunder or to have acquiesced in any default in or breach of any of the
terms and conditions hereof.  No failure to exercise, nor any delay in
exercising, on the part of any party hereto, any right, power or privilege
hereunder shall operate as a waiver thereof.  No single or partial exercise of
any right, power or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power or privilege.  No
remedy set forth in this Agreement or otherwise conferred upon or reserved to
any party shall be considered exclusive of any other remedy available to any
party, but the same shall be distinct, separate and cumulative and may be
exercised from time to time as often as occasion may arise or as may be deemed
expedient.

         Section 12.12      Communications.  The Group and Administrator,
Parent and their Affiliates agree that good communication between the parties
is essential to the successful performance of this Agreement, and each pledges
to communicate fully and clearly with the other on matters relating to the
successful operation of the Practice.

         Section 12.13      Captions.  The captions in this Agreement are for
convenience of reference only and shall not limit or otherwise affect any of

                                SERVICE AGREEMENT


            This Service Agreement (this "Agreement"), dated effective as of
_______________, 1997, is entered into by and among American Physician Partners,
Inc., a Delaware corporation ("Parent"), M & S X-Ray Associates, P.A., a Texas
professional association ("Administrator"), and M & S Imaging Associates, P.A.,
a Texas professional association ("Group").

                                R E C I T A L S:

            A. The Group owns and operates a radiology medical practice in the
San Antonio, Texas Metropolitan area including at five (5) hospitals and
provides professional and technical radiology services to the general public
through individual physicians who are licensed to practice medicine in the State
of Texas and who are employed or otherwise retained by the Group.

            B. Administrator is in the business of owning certain assets of
medical practices and providing management, administrative, and other
non-medical radiological support services to radiological and radiation oncology
medical practices including, without limitation, furnishing necessary
facilities, equipment, non-physician personnel, supplies and non-physician
support staff services.

            C. The Group desires to obtain the services of Administrator in
performing such non-medical business functions so as to permit the Group to
devote its full professional time and attention to the rendering of professional
and technical radiology and related services to its patients.

            D. The Group and Administrator have determined a fair market value
for the services to be rendered by Administrator, and based on this fair market

            Section 3.1 General.

arrange for the services set forth in this Article III, and the costs, fees,
expenses and other disbursements incurred by Administrator or Parent in
connection therewith shall be included in Practice Expenses, except to the
extent such costs, fees or expenses are expressly included in Excluded Practice

services hereunder as is necessary or appropriate for the efficient operation of
the Practice, including, without limitation, performance of some of the business
office functions at locations other than the Practice. Except to the extent
necessary to comply with applicable laws, regulations or professional ethical

assistance to Administrator as is reasonably required by Administrator to
perform its services hereunder. Administrator shall cause its employees, to
comply with all applicable federal, state and local laws, rules and regulations
in Administrator's provision of services hereunder.

            (b) Alternative Management Arrangements.

the services set forth in this Article III in a manner reasonably consistent
with commercially available services offered by third party providers of
physician practice management services of the type and scope offered by

commercially available services. Administrator shall deliver to the Group within
thirty (30) days after receipt by Administrator of such written notice a written
plan detailing the methods and procedures Administrator, Parent or their
Affiliates shall utilize to restore the level of service contemplated by this
Agreement. In the event Administrator fails to restore the level of service
contemplated by this Agreement in accordance with such plan submitted or in any
event within ninety (90) days, the Group shall be entitled to reimbursement by
Administrator for the reasonable costs and expenses of obtaining such service on
a temporary basis until such time Administrator demonstrates its ability to
perform such service at the level contemplated by this Agreement. Nothing
contained in this subsection (b)(i) shall be construed to limit the Group's
ability to provide notice of a Material Administrator Default pursuant to
Section 10.3(b) of this Agreement.

                (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service

to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

Administrator deposit any Professional Revenues and/or Technical Revenues into
the Deposit Account, any withdrawal of any funds from the Deposit Account not
authorized by the express terms of this Agreement or any other written agreement
executed by each of the parties, or any revocation of or attempt to revoke the
Transfer Order (otherwise than upon expiration or termination of this
Agreement), will constitute a breach of this Agreement and will entitle
Administrator, in addition to any other remedies it may have at law or in
equity, to seek a court ordered assignment of the rights provided to
Administrator pursuant to subparagraph (i) above.

                (iii) All monies shall be accounted for by Administrator as
being distinctly attributable to the Group. The Group may perform the functions
or exercise the rights set forth in this Section 3.2(b) only with the prior
written consent of Administrator. The Group shall execute such documents in form
and substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

            (c) Accounting. Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of
the Practice, and Administrator shall perform all bookkeeping and accounting
services necessary or appropriate for the efficient operation of the Practice,
including the maintenance, custody and supervision of business records, ledgers
and reports;



                                       13

the establishment, administration and implementation of accounting procedures,
controls and systems; and implementation and management of computer-based
management information systems. The Group and its authorized representatives
shall have the right to review all financial books and records maintained by
Administrator relating to the operation of the Practice and to the cash
management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

            (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

            (e) Purchase of Accounts Receivable and Right of Offset. Effective
each business day of the month and subject to applicable law, Administrator
shall purchase all accounts receivable of the Group arising during the day or
days just ended and shall make payment to Group therefor or offset, without
further notice or authorization, sums owed Administrator by Group as the parties
have agreed herein. The purchase price shall be an amount equal to the aggregate
face amount of the accounts receivable being sold less contractual adjustments
and estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

            (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication
services and medical transcribing services; provided, however, that the Group
may elect to prepare its own Tax Returns, in which case, the cost of preparing
such Tax Returns in excess of $2,500 per annum shall be included in Excluded
Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group
containing a balance sheet, income statement and monthly operational reports
which detail payments, charges and accounts receivable statistics, monthly
reconciliation reports on cash management and any other financial reports
reasonably requested by a member of the Joint Planning Board designated by the
Group, which shall be delivered to the Group as soon as practicable, but no



                                       14

<PAGE>   20

later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

            (g) Records and Files.

                (i) Administrator's Business and Financial Records. At all times
during and after the term of this Agreement, including any extensions or
renewals hereof, all business records, including but not limited to, business
agreements, books of account, personnel records, general administrative records
and all information generated under or contained in the management information
system pertaining to Administrator's obligations hereunder, and other business
information of Administrator of any kind or nature, except for patient medical
records and the Group's Records (as defined in subparagraph (ii) below), shall
be and remain the sole property of Administrator; provided that during and after
termination of this Agreement, the Group shall be entitled to reasonable access
to such records and information, including the right to obtain copies thereof in
any media reasonably requested by the Group, for any purpose related to patient
care or the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years. Administrator hereby agrees
to preserve the confidentiality of such patient medical records and to use the
information in such records only for the limited purposes necessary to perform
management services and, within the limits of its responsibilities hereunder, to
ensure that provision is made for appropriate care for patients of the Practice.

                (ii) The Practice's Business and Financial Records. At all times
during and after the term of this Agreement, the business agreements, financial,
operational, corporate and personnel records and information relating
exclusively to the business and activities of the Group and patient medical
records and charts (hereinafter referred to as the "Group's Records") shall be
and remain the sole property of the Group.

                (iii) Access to Records. At all times during and after the term
of this Agreement, each party and its authorized agents shall be entitled, upon
request and with reasonable advance notice, to obtain access (within not more
than 30 days following receipt of such notice by the other party or parties) to
all records of the other party directly related to the performance of such
party's



                                       15

<PAGE>   21

obligations pursuant to this Agreement; provided, however, that such right shall
not allow for access to patient, medical and other records that must be kept
confidential as required by law. Either party, at its expense, shall have the
right to make copies in any media of any records to which it has access pursuant
to this subparagraph (iii).

                (iv) Compliance with Law. The management of all files and
records by Administrator and the Group shall comply with all applicable federal,
state and local statutes and regulations.

            (h) Collections. Subject to the consent requirement contained in
Section 3.2(b)(i)(F), Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees and
pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

            Section 3.3 Facilities.

            (a) Premises. Administrator shall make available to the Group the
Premises that are described in Exhibit 3.3(a) attached hereto and such other
improvements made by Administrator or Parent for the use of the Group hereunder.
The Premises shall be subject to such expansion or reduction as reviewed and
approved by the Joint Planning Board. Administrator shall obtain for the Group
all utilities reasonably required in connection with the use of the Premises and
shall provide for the proper cleanliness of the Premises, including normal
janitorial and maintenance services and refuse disposal, including medical
waste. Administrator shall maintain the Premises in good condition and make or
cause to be made all necessary repairs thereto.

            (b) Personal Property. Administrator shall provide the Group with
the use of the equipment, furniture, fixtures, furnishings and other personal

such other equipment, furniture, fixtures, furnishings and other personal
property necessary or appropriate for the efficient operation of the Practice
acquired by Administrator or Parent (subject to review and approval of the Joint
Planning Board) for the use of the Group pursuant to the terms hereof
(collectively, the "Personal Property"). Administrator shall maintain the
Personal Property in good condition and make or cause to be made all necessary
repairs thereto.

            (c) Expenses. All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the
Premises and the Personal Property, including, without limitation, all
reasonably necessary costs of repairs, maintenance and improvements, utility
expenses (i.e., telephone, electric, gas and water), janitorial services, refuse
disposal, real or personal property lease cost payments and



                                       16

<PAGE>   22

expenses, interest, refinancing expenses, depreciation, loss on disposition of
assets, taxes and casualty, liability and other insurance, shall be included in
Practice Expenses. To the extent the Premises or Personal Property are used in
connection with the Professional Operations, the costs and expenses associated
with such usage shall be allocated between Professional Expenses and Technical
Expenses as approved by the Joint Planning Board.

            (d) Disposition. Subject to provisions contained in existing
agreements to which Administrator or Parent is or becomes a party and, where
necessary and appropriate for the efficient operation of the Practice, nothing
herein shall be construed as precluding Administrator or Parent from selling,
leasing or otherwise disposing of all or any part of the Premises, Personal
Property, real property, improvements, trade names, trademarks and other
intangible property; provided, however, any such sale, lease or disposition
shall be subject to the prior review and approval of the Joint Planning Board
and shall not eliminate or diminish Administrator's obligations hereunder.

            (e) No Warranties or Representations. The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

            Section 3.4 Acquisition and Assistance.

            (a) Employment of Physicians. Subject to consultation with the Joint
Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice. Subject to
consultation with the Joint Planning Board, in the event that a decision is made
by the Group to pursue the employment of selected physicians, if requested by
the Group, Administrator will provide recruiting, consulting, negotiating and
other advisory services in connection with such transaction. Notwithstanding the
preceding, as set forth in and subject to the provisions of Section 4.1 hereof,
the Group shall have complete control of and responsibility for the hiring of
all Physician Employees and Physician Extender Employees.

            (b) Acquisitions. In the event that the Group contemplates acquiring
or affiliating with a physician group, practice or other entity, and such
acquisition or affiliation involves the use or expenditure of Administrator's
and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a
result of such an acquisition or affiliation including, without limitation,
capital and personnel (collectively, the "Resources"),



                                       17

<PAGE>   23

then the Group shall first consult with the Joint Planning Board and
Administrator, and any decision to make such affiliation or acquisition shall be
subject to prior approval of Administrator, which decision of the Administrator
shall be provided to the Group in a reasonable and timely manner following
satisfactory review of the physician group, practice or other entity to be
acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto. If such contemplated acquisition or affiliation does not
involve the use or expenditure of any of Administrator's and/or Parent's
Resources, then such decision shall be in the sole discretion of the Group.
Notwithstanding any provision contained herein to the contrary, any person or
entity with which the Group affiliates or acquires shall be subject to the terms
and conditions of this Agreement. If a decision is made to proceed with any
affiliation or acquisition of a physician group or practice, the Group may seek
from Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

            Section 3.5 Financial Planning and Budgeting.

            (a) Budgeting. Administrator shall collaborate with the Group and
the Joint Planning Board in the preparation of all annual capital and operating
budgets. These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors. For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board. The
projected annual operating budget for each subsequent year shall be subject to
the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice. For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

            (b) Capital Expenditures. Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:



                                       18

<PAGE>   24

                (i) Budgeted Expenditures. All budgeted capital expenditures and
improvement projects shall be subject to final review and approval by the Joint
Planning Board prior to the making of any actual expenditure. Such review and
approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.

                (ii) Non-Budgeted Expenditures. Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared by
the Joint Planning Board in consultation with the Group and Administrator. All
requests for non-budgeted capital expenditures and improvements at or for the
benefit of the Practice in excess of either $75,000 individually or an aggregate
amount equivalent to $2,500 multiplied by the number of Full-time Physician
Employees employed at the time the capital budget for such Group for the
applicable year is determined (provided, however, that such aggregate amount
shall not exceed $250,000 for any calendar year) must be approved by the Board
of Directors of Parent or by any committee specifically designated by the Board
of Directors of Parent for such purposes.

            (c) Capital Improvements and Expansion. Subject to Section 3.5(b),
any site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

            Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise



                                       19

<PAGE>   25

cease to utilize such employee in providing services to the Practice hereunder.
Administrator shall maintain established working relationships wherever possible
and Administrator shall make every effort consistent with sound business
practices to honor the specific requests of the Group with regard to the
assignment of Administrator's employees.

            Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors"). Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning Board,
be the responsibility of the Group. Notwithstanding the preceding language, if a
contract or relationship between any Managed Care Payor and the Group involves
or affects a contract or relationship with any other physician group or practice
serviced or managed by Administrator, Parent or any of their Affiliates (the
"Other Practices") and a consensus among the Group and the Other Practices
cannot be reached regarding the contract or relationship, then the ultimate
decision as to the approval, disapproval, termination or amendment of such
contract or relationship involving the Group, the Other Practices and such
Managed Care Payor shall be determined by the affirmative vote of the Physician
Board Members (as defined below) who hold a majority of the Group Voting Power
(as defined below). For purposes of this Section 3.7, (i) the term "Physician
Board Members" shall mean (a) those members appointed by the Group who serve on
the Joint Planning Board and (b) those persons appointed by the Other Practices
who serve on the Other Practices' joint boards (in a similar capacity to the
Joint Planning Board) as part of their contractual relationship with Parent,
Administrator or any of their Affiliates, and (ii) the term "Group Voting Power"
shall mean the total voting percentage which may be cast by the Physician Board
Members on a collective basis, with the percentage of votes able to be cast by
any Group or Other Practice, as applicable, shall be equal to the quotient
determined by dividing (x) the total estimated annual professional revenues to
be generated by the Group from such Managed Care Contract as determined by
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion, by (y) the total estimated annual professional revenues to be
generated by the Group and all Other Practices from such Managed Care Contract
as determined by the Administrator, Parent or their Affiliates, as appropriate,
in its sole discretion.

            Section 3.8 Inventory and Supplies. Administrator shall order,
purchase and provide to the Group on a timely basis



                                       20

<PAGE>   26

inventory and supplies, and such other ordinary, necessary or appropriate
materials which are requested by the Group and which the Group shall reasonably
determine to be necessary in the operation of the Practice on the same terms
commercially available to Administrator. Such inventory, supplies and other
materials shall be included in Practice Expenses at their cost to Parent or
Administrator, as the case may be.

            Section 3.9 Advertising and Public Relations. In consultation with
the Joint Planning Board, Administrator shall implement (and design where
requested) an appropriate local public relations or advertising program on
behalf of the Practice, with appropriate emphasis on public awareness of the
availability of services at the Practice. Prior to publication or distribution
of such marketing or public relations material or information, Administrator
shall submit such material to the Group for its review and approval, which shall
not be unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and advertising programs shall be
conducted in compliance with applicable standards of medical ethics, laws and
regulations.

            Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program
shall be included in Administrator Expenses; provided, however, that any
expenses related to such program that are incurred for services provided solely
for the direct benefit of the Practice shall be included in Practice Expenses.

            Section 3.11 Other Consulting and Advisory Services. Administrator
will provide such consulting and other advisory services as reasonably requested
by the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

            Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to



                                       21

<PAGE>   27

Section 10.3(b), for so long as such events continue and for a reasonable period
of time thereafter; provided however that if such events continue and
Administrator is not able to perform any material portion of the services
required hereunder for a period of 120 consecutive days or more, either
Administrator or Group may terminate this Agreement by written notice to the
other.


                                   ARTICLE IV

                            Obligations of the Group

            Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender
Employees, and other employees who may have malpractice exposure or liability,
are insurable and by participating in an on-going risk management program.

            Section 4.2 Professional Services. The Group shall provide
professional services to its patients in compliance at all times with ethical
standards, laws, rules and regulations applicable to the operations of the
Practice, the Physician Employees and Physician Extender Employees. The Group
shall ensure that each Physician Employee and each Physician Extender Employee
has all required licenses, credentials, approvals or other certifications to
perform his or her duties and services for the Practice and, in the event that
the Group becomes aware of any disciplinary actions or medical malpractice
actions initiated against any Physician Employee or Physician Extender Employee,
the Group shall promptly inform Administrator of such action and the underlying
facts and circumstances. If required by applicable law, any state or federal
regulatory agency or any contractual



                                       22

<PAGE>   28

obligations, the Group shall carry out a program to monitor the quality of
medical care practiced at the Practice; provided, however, that the preceding
language shall not limit the Group's obligation to participate in or comply with
any programs established by Administrator or Parent for purposes of ensuring
that the Group complies with applicable law. The Group shall employ Physician
Employees and Physician Extender Employees as is necessary to provide efficient
medical care to patients of the Practice.

            Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery
items on prepaid Managed Care Contracts which are authorized and permitted by
such contracts. A copy of such agreements and any amendment thereto shall be
provided to Administrator for review no later than thirty (30) days prior to the
proposed effective date thereof.

            Section 4.4 Group's Internal Matters. The Group shall be responsible
for matters involving its corporate governance, employees and similar internal
matters, including, but not limited to, preparation and contents of such reports
to regulatory authorities governing the Group that the Group is required by law
to provide, distribution of professional fee income among the Group Physician
Stockholders, disposition of the Group's property and stock (subject to any
restrictions contained herein), hiring and firing of its employees, licensing
and implementing all compliance



                                       23

<PAGE>   29

plans and procedures as described in Section 4.6. Except for the expenses
attributable to the distribution of professional fee income among the Group
Physician Stockholders, which will be included in Excluded Practice Expenses,
the costs incurred in connection with the foregoing matters shall be Practice
Expenses.

            Section 4.5 Name. Administrator agrees that the Group shall be
entitled to use on a non-exclusive and non-transferable basis for the term of
this Agreement the names set forth on Schedule 4.5 as may be necessary or
appropriate in the performance of the Group's services and obligations
hereunder.

            Section 4.6 Compliance with Laws. The Group shall, and shall use its
best efforts to cause the Physician Employees, Physician Extender Employees and
other employees of the Group to, comply with all applicable federal, state and
local laws, rules, regulations and restrictions in the conduct of the Practice's
business. Without limiting the generality of the foregoing, the Group shall
comply and shall cause each Physician Employee, Physician Extender Employee and
other employee of the Group to comply, with all laws applicable to the operation
of the Practice in the generation, transportation, treatment, storage, disposal
or other handling of radioactive, medical, biological or hazardous materials or
waste, and the Group shall not, and shall use its best efforts to prohibit any
Physician Employee, Physician Extender Employee and any employee of the Group
from:

            (a) entering into any contract, lease, agreement or arrangement,
including, but not limited to, any joint venture or consulting agreement, to
provide services, lease space, lease equipment or engage in any other venture or
activity with any physician, hospital, pharmacy, home health agency or other
person or entity which is in a position to make or influence referrals to, or
otherwise generate business for, the Practice, if such transaction is in
violation of any applicable law, rule or regulation;

            (b) knowingly and willfully making or causing to be made a false
statement or representation of a material fact in any application for any
benefit or payment from a Managed Care Payor or any other Payor;

                              Joint Planning Board

            Section 5.1 Formation and Operation of the Joint Planning Board.

            (a) The parties hereto shall establish the Joint Planning Board
which shall be responsible for developing long-term strategic planning
objectives and management policies for the overall operation of the Practice and
shall facilitate communication and interaction between Administrator and the
Practice. The Joint Planning Board shall consist of no less than three (3) or
more than six (6) members. Administrator shall designate, in its sole
discretion, two (2) members of the Joint Planning Board, who shall serve at the
pleasure of Administrator and who may be removed or replaced by Administrator at
any time. The Group shall designate, in its sole discretion, no less than one
(1) or more than four (4) members of the Joint Planning Board, who shall serve
at the pleasure of the Group and who may be removed and replaced by the Group at
any time. Each member appointed by Administrator shall be entitled to one (1)
vote per member, and each member appointed by the Group shall be entitled to
that number of votes equal to the quotient determined by dividing (x) two (2)
votes by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

            (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint



                                       26

<PAGE>   32

Planning Board. A validly executed proxy which does not state that it is
irrevocable shall continue in full force and effect unless (i) revoked by the
member executing it, before the vote pursuant to that proxy, by a writing
delivered to the Joint Planning Board stating that the proxy is revoked, or by a
subsequent proxy executed by, or attendance at the meeting and voting in person
by, the member executing the proxy; or (ii) written notice of the death or
incapacity of the maker of that proxy is received by the Joint Planning Board
before the vote pursuant to that proxy is counted; provided, however, that no
proxy shall be valid after the expiration of eleven (11) months from the date of
the proxy, unless otherwise provided in the proxy.

            Section 5.2 Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

            (a) Capital Improvements and Expansion. Subject to Section 3.5(b),
any site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

            (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess
of five percent (5%) to the annual capital or operating budgets.

            (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

            (d) Patient Fees. As a part of the annual operating budget, in
consultation with and upon recommendation of the Joint Planning Board, the Group
shall review and adopt the fee schedule for all professional services rendered
by the Practice.

            (e) Ancillary Services and Fees. The Joint Planning Board shall
approve Practice-provided non-medical ancillary services (including, without
limitation, fees for technical services which do not generate Professional
Revenues) based upon the pricing, access to, and quality of such services and
shall review and adopt the fee schedule for all ancillary services.

the priority of capital expenditures in accordance with Section 3.5(b) hereof.

specifically provided herein, the act of the members holding a majority of the
voting power of the Joint Planning Board shall be the act of the Joint Planning
Board. The Group agrees that, unless the following are approved in advance by
the Joint Planning Board and such act of the Joint Planning Board includes the
approval by both of the members designated by Administrator, it shall take no
action or implement any decision that would (i) require Administrator to expend
funds or incur obligations beyond those set forth under Sections 3.5 or 5.2 of
this Agreement; (ii) have a material adverse effect on the amount of
Administrator's management fee under Article VII; or (iii) otherwise have a
material adverse effect on Administrator's financial interests under this
Agreement. Except as provided in the prior sentence, the Group and Administrator
hereby agree to be bound by the act of the Joint Planning Board if such act was
approved by the members holding at least a majority of the voting power of the
Joint Planning Board. No action of the Joint Planning Board shall be effective
unless authorized by the members holding a majority of the voting power of the
Joint Planning Board present or represented by proxy at the applicable meeting.
In the event that a matter cannot be resolved by the Joint Planning Board due to
a tie vote, and no compromise can be reached, then either (x) the Board of
Directors of Parent or (y) a committee designated by the Board of Directors of
Parent containing at least one (1) physician member will make a final
determination on the matter in dispute provided that both the Group and
Administrator shall have had an opportunity



                                       28

<PAGE>   34

(15) business days following each meeting.

            (a) Regular Meetings. The Joint Planning Board shall hold not less

the members may determine.

            (b) Special Meetings. A special meeting of the Joint Planning Board
may be called by fifty percent (50%) of the votes.

            (c) Notice Requirement. A member calling a special meeting must
provide all other members with ten (10) days' advance written or telephonic
notice. Notice must be given or sent to the member's address or telephone number
as shown on the records of the Joint Planning Board. Notice may be delivered
directly to each member or to a person at the member's principal place of
business who would reasonably be expected to communicate that notice promptly to
the member.

            (d) Waiver of Notice Requirement.

                (i) Written Waiver, Consent or Approval. Notice of a special
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the special meeting. Such waiver,
consent or approval need not specify the purpose of the special meeting. All
such waivers, consents, and approvals shall be filed with the Joint Planning
Board records or made a part of the minutes of the special meetings.

                (ii) Failure to Object. Notice of special meeting need not be

Agreements, including, without limitation, the Restrictive Covenants. The costs
and expenses of such enforcement shall be included in Professional Expenses and
all damages and other amounts recovered thereby shall be included in
Professional Revenues. In the event that, after a request by



                                       35

<PAGE>   41

Administrator, the Group does not pursue any remedy that may be available to it
by reason of a breach or default of the Restrictive Covenants or any other
provision of the Stockholder Employment Agreements and, to the extent permitted
under applicable law, the Physician Employee Employment Agreements, upon the
request of Administrator, the Group shall assign to Administrator such causes of
action and/or other rights it has related to such breach or default and shall
cooperate with and provide reasonable assistance to Administrator with respect
thereto; in which case, all costs and expenses incurred in connection therewith
shall be borne by Administrator and shall be included in Administrator Expenses,
and Administrator shall be entitled to all damages and other amounts recovered
thereby. In the event the Purchase Assets are acquired by the Group pursuant to
Article X, the obligation of the Group to enforce Restrictive Covenants shall be
limited to enforcement of non-solicitation and nondisclosure of
confidential/proprietary information covenants.

            Section 6.4 Remedies. Administrator and the Group acknowledge and
agree that a remedy at law for any breach or attempted breach of the provisions
of this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period, scope of activity restricted
and/or the geographical area applicable to such provision of the Restrictive
Covenants or this Article VI. The invalidity or non-enforceability of any
provision of the Restrictive Covenants or this Article VI in any respect shall
not affect the validity or enforceability of the remainder of the Restrictive
Covenants or this Article VI or of any other provisions of this Agreement.

            Section 6.5 Condition Precedent to Release of Obligations. In the
event a Group Physician Stockholder or Full-time Physician Employee terminates
his/her employment agreement with the Group, the Group shall be entitled to
release (with the consent of Administrator in its sole and absolute discretion)
such Group Physician Stockholder or Full-time Physician Employee from the
restrictive covenants contained in Section 6.2, above. In the event the Group
elects to release such Group Physician Stockholder or Full-time Physician
Employee, the Group hereby covenants that it



                                       36

<PAGE>   42

shall obtain a formal agreement between each Group Physician Stockholder or
Full-time Physician Employee, as the case may be, and Administrator which
provides that, for a period of two (2) years following termination of any
employment agreement with the Group, such Group Physician Stockholder or
Full-time Physician Employee agrees to (a) engage Administrator as the sole and
exclusive manager and administrator of the non-medical functions and services of
said Group Physician Stockholder's or Full-time Physician Employee's medical
practice and (b) pay to Administrator the identical amount [NY only] of revenues
paid by the Group to the Administrator attributable to such Group Physician
Stockholder or Full-time Physician Employee derived from such Group Physician
Stockholder's or Full-time Physician Employee's performance of professional
medical services within 15 miles of any Practice Site.

            Section 6.6 Service Area Rights and Obligations.

            (a) Primary Service Area. During the term of this Agreement and
within any Primary Service Area, Parent, Administrator or their Affiliates shall
not, without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary
information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and work effort
required and (y) the Group shall not be required to employ any Radiologist
previously associated with such Professional Service Opportunity.

            (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a



                                       37

<PAGE>   43

Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half of the time during which the
Administrator, Parent or their Affiliates must respond to an offer described in
the Administrator's Notice, the Group shall deliver to Administrator a written
notice stating whether or not the Group elects to accept or reject the New
Professional Service Opportunity which election shall be binding on the Group.
If the Group does not elect to exercise the right or fails to provide the notice
to Administrator within the time frame herein provided, Administrator shall be
released from the right of first offer with respect to that particular New
Professional Service Opportunity. Prior to consummating any asset acquisition,
merger or other consolidation of any Radiologist, group of Radiologists, or
professional corporation or association (or other professional entity) whose
owners are Radiologists within any Secondary Service Area, Administrator shall
first consult with the Joint Planning Board.

            (c) Determination of Primary and Secondary Service Area. The
existence and location of each of the Group's Primary Service Areas and
Secondary Service Areas shall be determined each time the Group, Parent,
Administrator or their Affiliates propose an acquisition, management
relationship, Professional Service Opportunity or New Professional Service
Opportunity as contemplated in subsections (a) and (b) above.

            (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

            (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

            "New Professional Service Opportunity" shall mean a Professional
Service Opportunity pursuant to which the Group or any other member of an APPI
Group managed by Parent, Administrator or their Affiliates is not currently
providing professional Radiology services.

            "Primary Service Area" shall mean that area within a five (5) mile
radius from any imaging center owned, operated or managed by Administrator,
Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.

            "Professional Service Opportunity" shall mean any opportunity to
perform professional Radiology services for any



                                       38

<PAGE>   44

hospital, hospital system or imaging center under a formal agreement with such
entity.

            "Radiologist" shall mean and include both radiologists and radiation
oncologists.

            "Radiology" shall mean and include diagnostic imaging,
interventional radiology and radiation oncology services.

            "Secondary Service Area" shall mean (i) during the 12- month period
following the Acquisition Effective Date, that area which extends ten (10) miles
beyond the boundary of any Primary Service Area and (ii) during the remaining
term of this Agreement, that area which extends five (5) miles beyond the
boundary of any Primary Service Area.

            Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

            Section 6.8 Definition. The term "Full-time Physician Employee" as
used in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.


                                   ARTICLE VII

                       Financial and Security Arrangements

            Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being



                                       39

<PAGE>   45

paid to Administrator in consideration of the services provided and the
substantial commitment and effort made by Administrator hereunder and that such
fees have been negotiated at arms' length and are fair, reasonable and
consistent with fair market value. Administrator shall be paid the service fee
(the "Service Fee") as set forth on Exhibit 7.1 hereto. Payment of the Service
Fee is not intended to and shall not be interpreted or implied as permitting
Administrator to share in the Group's fees for medical services but is
acknowledged as the negotiated fair market value compensation to Administrator
considering the scope of services and the business risks assumed by
Administrator.

            Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates based
upon available information for such month, and adjustments to the estimated
payments shall be made to reconcile final amounts due under Section 7.1 on the
next Payment Date.

            Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

            Section 7.4 Security Agreement. In order to enforce its rights
granted hereunder and subject to applicable law, the Group shall execute a
Security Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security



                                       40

<PAGE>   46

Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

            Section 7.5 Adjustment of Fees. In addition to the adjustments
provided for in Section 7.2, Service Fees payable by Group pursuant to this
Article VII shall be adjusted as appropriate upon agreement of the parties upon
the divestiture or acquisition by the Group of, or affiliation with, a radiology
or diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee and to other related provisions of
this Agreement shall be a joint decision of the parties, shall be memorialized
in a written amendment to this Agreement, and shall be based upon the
methodology used to generally determine Services Fees hereunder.

            Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

            (a)         payment of all accrued Practice Expenses for the prior
                        month (subject to the proviso in the preceding
                        sentence);

            (b)         payment of the accrued Service Fee for the prior month;

            (c)         payment of outstanding balance of all amounts advanced
                        to the Group through the end of the prior month, and
                        applicable interest thereon (as contemplated in Section
                        7.3); and

            (d)         payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the



                                       41

<PAGE>   47
end of each calendar month (or the first preceding day if the 15th day is not a
business day).


                                  ARTICLE VIII

                                     Records

            Section 8.1 Records. All records relating in any way to the
operation of the Practice (other than Group Records) shall, subject to the
obligations of the Practice to maintain patient medical records pursuant to
Section 3.2(g), at all times be the property of Administrator as set forth in
Section 3.2(g). During the term of this Agreement, and for a reasonable time
thereafter, the Group or its agents shall have reasonable access during normal
business hours to the Group's and Administrator's personnel and financial
records relating to the Practice, including, but not limited to, records of
collections, expenses and disbursements as kept by Administrator in performing
Administrator's obligations under this Agreement, and the Group may copy any or
all such records.


                                   ARTICLE IX

                          Insurance and Indemnification

            Section 9.1 Insurance to be Maintained by the Group.

            (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.



                                       42

<PAGE>   48

            (b) The Group, Administrator and Parent each waives any right one
may have against the other, to the extent allowed by the waiving party's
insurance coverage, on account of any loss or damage occasioned to any party by
another party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

            Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.

            Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.

            Section 9.4 Additional Insureds. The Group and Administrator agree
to use their reasonable efforts to have each other named as an additional
insured on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

            Section 9.5 Indemnification.

            (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the



                                       43

<PAGE>   49

Group) harmless, from and against any and all liabilities, losses, damages,
claims, causes of action and expenses (including reasonable attorneys' fees),
not covered by insurance (including self-insured insurance and reserves),
whenever arising or incurred, that are caused or asserted to have been caused,
directly or indirectly, by or as a result of the performance of medical services
or the performance of any intentional acts, negligent acts or omissions by the
Group and/or its shareholders, employees and/or subcontractors (other than
Administrator, Parent, Affiliates or their employees, officers, directors,
agents, attorneys and consultants) during the term of this Agreement. Provided,
however, that in the event an indemnification obligation under the preceding
sentence arises as of the result of any act or omission of a person who is an
officer, shareholder or other equity holder, director, employee, agent, attorney
or consultant of Administrator, Parent or any of their Affiliates (other than in
connection with the activities of the Joint Planning Board), such person shall
not be entitled to indemnification in connection therewith and any other
adjustment as is equitable shall be made to the Group's indemnification
obligation arising thereby.

            (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or
incurred, that are caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts or omissions by Administrator, Parent or Affiliates and/or any of
their respective shareholders, employees and/or subcontractors (other than the
Group or its employees) during the term of this Agreement. Provided, however
that in the event an indemnification obligation under the preceding sentence
arises as a result of any act or omission of a person who is an officer,
shareholder or other equity holder, director, employee, agent, attorney or
consultant of the Group (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
Administrator's or Parent's indemnification obligation arising thereby.


                                    ARTICLE X

                              Term and Termination

            Section 10.1 Term of Agreement. This Agreement shall commence on the
date hereof and shall expire on the 40th anniversary hereof unless earlier
terminated pursuant to the terms



                                       44

<PAGE>   50

of either Section 10.3 or Section 10.4 or automatically extended pursuant to the
terms of Section 10.2.

            Section 10.2 Extended Term. Unless earlier terminated as provided
for in either Section 10.3 or Section 10.4, the term of this Agreement shall be
automatically extended for additional terms of five (5) years each, unless
either party delivers to the other party, not less than twelve (12) months nor
earlier than fifteen (15) months prior to the expiration of the preceding term,
written notice of such party's intention not to extend the term of this
Agreement.

            Section 10.3 Termination by the Group. The Group may, in its sole
discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

            (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

            (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not the
obligation, to cure any Material Administrator Default. Notwithstanding anything
to the contrary in this Agreement, following receipt by Administrator of the
notice of a Material Administrator Default and until such Material Administrator
Default shall be cured, the Group may take such action as may be reasonably
required to cover such Material Administrator Default so as to maintain for the
Group the same level of service as before the Material Administrator Default,
without prejudicing in any way the Group's other rights and remedies, and may
offset all of its costs from the amounts which may otherwise be due to
Administrator under this Agreement.

<PAGE>   51

            (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

            Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

            (a) The Group shall default in the performance of any material duty
or material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that
individual from participating in or from receiving reimbursement under any
program funded by the federal government or



                                       46

by any state government, notwithstanding any available post-sanction remedies,
or (4) is otherwise disciplined by any licensing, regulatory or professional
entity or institution, the result of any of which event does or is reasonably
expected to materially adversely affect the Practice, the result of any of which
event described in subparagraphs (1) through (4) above, in the absence of
termination of a Physician Employee or a Physician Extender Employee or other
action of the Group to monitor and cure such act or conduct by such employee,
does or reasonably would be expected to materially and adversely affect the
Practice or the Group. Notwithstanding anything to the contrary in this
Agreement, following receipt by the Group of the notice of a Material Group
Default, and until such Material Group Default shall be cured, the Administrator
may take such action as may be reasonably required to cover such Material Group
Default so as to maintain for the Administrator the same level of service at the
Premises as before the Material Group Default, without prejudicing in any way
Administrator other rights and remedies, and may offset all of its costs of
cover from amounts which may otherwise due to the Group under this Agreement.

            (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

            (c) At any time during the five-year period following the
Acquisition Effective Date if more than thirty-three and one-third percent (33
1/3%) of the total number of Group Physician Stockholders and Full-time
Physician Employees retained or employed by the Group at the time of the
Acquisition Effective Date are no longer employed or retained by the Group for
reasons other than (i) death, (ii) permanent disability, (iii) loss of a
hospital contract or privileges for reasons other than voluntary resignation by
the Group or a failure to renew or a failure to respond to a reasonable proposal
to extend the term of such contract or (iv) voluntary closing of facilities by
Administrator. For purposes of this Section 10.4(c), if Parent and/or
Administrator are notified in writing by the Group at or prior to the
Acquisition Effective Date of any Physician Employee [or Physician Extender
Employee] that intends to retire prior to expiration of such five-year period,
then such Physician Employee or Physician Extender Employee shall not be counted
for purposes of determining the above percentage.

            Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:



                                       47

<PAGE>   53

            (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

            (b) Upon the expiration of this Agreement pursuant to Sections 10.1
or 10.2.

            Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator, and/or Parent the Purchase
Assets and assume the Practice Related Liabilities below:

            (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator, and/or Parent or its
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's or their Affiliates' accounting and financial records (the "Purchase
Assets"), including, but not limited to, without duplication, (i) all equipment,
furniture, fixtures, furnishings, inventory, supplies, improvements, additions
and leasehold improvements utilized by the Practice, (ii) any real estate owned
by Administrator, Parent or Affiliates that is occupied by or used primarily for
the benefit of the Practice, (iii) all unamortized intangible assets (including,
without limitation, goodwill) set forth on the financial statements of
Administrator, Parent or their Affiliates used solely in connection with the
Practice or otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

            (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and its Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

            (c) Purchase Price. The Purchase Price shall be the lesser of (i)
Fair Market Value of the Purchase Assets subject to the



                                       48

<PAGE>   54

assumption of the Practice Related Liabilities or (ii) the value of the Actual
Consideration (defined below)(alternatively, the "Purchase Price"); provided,
however, the Purchase Price shall not be less than the net book value of the
Purchase Assets at the Termination Date. The Purchase Price shall be paid
pursuant to Section 10.7. For purposes of this subparagraph (c), the term
"Actual Consideration" shall mean (i) cash consideration paid to the Group
pursuant to the Acquisition Agreement and (2) an amount equal to the number of
shares of Parent Common Stock (as adjusted for stock splits, stock dividends,
recapitalizations, reorganizations, or any similar transaction whereby the
Parent Common Stock is increased or decreased or exchanged for a different
number or kind of securities) issued pursuant to the Acquisition Agreement
multiplied by the fair market value of Parent Common Stock immediately prior to
the time that a Termination Notice is provided pursuant to Section 10.7. The
Purchase Price shall be appropriately adjusted to offset and account for any
monetary obligations of the Group or Administrator owing to the other as
provided herein.

            (d) Exercise of Option.

                (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

            (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

            Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to



                                       49

<PAGE>   55

the conditions set forth below, at the Purchase Closing, Administrator and/or
its Affiliates, as the case may be, shall transfer and assign the Purchase
Assets to the Group, and in consideration therefor, the Group shall (a) pay to
Administrator, Parent and/or their Affiliates an amount in cash or, at the
option of the Group (subject to the conditions set forth below), Parent Common
Stock (valued pursuant to Section 10.6(c) hereof), or some combination of cash
and Parent Common Stock equal to the Purchase Price and (b) assume the Practice
Related Liabilities. The structure of the transaction set forth in this Section
10.7 shall, if possible, be structured as a tax-free transaction under
applicable law. Each party shall execute such documents or instruments as are
reasonably necessary, in the opinion of each party and its counsel, to effect
the foregoing transaction. The Group shall, and shall use its best efforts to
cause each shareholder of the Group to, execute such documents or instruments as
may be necessary to cause the Group to assume the Practice Related Liabilities
and to release Administrator, Parent and/or their Affiliates, as the case may
be, from any liability or obligation with respect thereto. In the event the
Group desires to pay all or a portion of the Purchase Price in shares of Parent
Common Stock, such transaction shall be subject to the satisfaction of each of
the following conditions:

            (a) The holders of such shares of Parent Common Stock shall transfer
to Administrator, Parent and/or their Affiliates good, valid and marketable
title to the shares of Parent Common Stock, free and clear of all adverse
claims, security interests, liens, claims, proxies, options, stockholders'
agreements and encumbrances (not including any applicable securities
restrictions and lock-up arrangements with the Parent or any underwriter); and

            (b) The holders of such shares of Parent Common Stock shall make
such representations and warranties as to title to the stock, absences of
security interests, liens, claims, proxies, options, stockholders' agreements
and other encumbrances and other matters as reasonably requested by
Administrator, Parent and/or their Affiliates.

            In the event (i) the Fair Market Value of the Purchase Assets
exceeds net book value of the Purchase Assets, (ii) the Group has utilized
commercially reasonable efforts to obtain financing for such acquisition but is
unable to obtain such financing and (iii) there is either a Material
Administrator Default pursuant to Section 10.3(a) or (c) or a Material Group
Default pursuant to Section 10.4(b) triggering a sale of the Purchase Assets,
the Group shall be entitled to obtain financing from Administrator, Parent
and/or their Affiliates but only for the difference between the Fair Market
Value of the Purchase Assets and the net book value of the Purchase Assets. The
terms of such financing shall be for a five (5) year period at an interest rate
equal to the prime rate (as published in the Wall Street Journal) plus four
percent (4%) or such lesser rate as is required to be in conformance with all



                                       50

<PAGE>   56

applicable state and federal law. In the event the Group is entitled to obtain
financing from Administrator, Parent and/or their Affiliates the Group shall
execute and deliver to Administrator, Parent and/or their Affiliates all such
documentation necessary and appropriate to effectuate the financing transaction
including, without limitation, a secured promissory note, security agreement and
financing statements and such documentation shall contain such representations,
warranties and conditions customary to a secured transaction of this size.

            Section 10.8 Exception to Purchase. Notwithstanding anything
contained herein to the contrary, Administrator, Parent and/or their Affiliates
shall not be obligated to sell the Purchase Assets to the Group as provided in
Section 10.6(d)(i) above if the Group is not able to pay the Purchase Price
pursuant to the terms set forth above and assume the Practice Related
Liabilities at the Purchase Closing. In such event, the Group shall surrender
the Purchase Assets to Administrator, Parent and/or their Affiliates as of the
Purchase Closing. If the Practice fails to so surrender the Purchase Assets,
Administrator, Parent and/or their Affiliates may, if permitted by applicable
law, without prejudice to any other remedy which it may have hereunder or
otherwise, enter the Premises and take possession of the Purchase Assets and
expel or remove the Group and any other person who may be occupying the Premises
or any part thereof, by force if necessary, without being liable for prosecution
or any claim for damages therefor.

            Section 10.9 Effect Upon Termination. Upon the Termination Date,
except as provided below, this Agreement shall terminate and shall be of no
further force and effect and all further obligations of Administrator, Parent
and/or their Affiliates and the Group under this Agreement shall terminate
without further liability of the Administrator or Parent and/or their Affiliates
to the Group or the Group to the Administrator or Parent and/or their Affiliates
(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

            (a) Administrator and Parent and/or their Affiliates shall use their
best efforts to cooperate with the Group for the appropriate transfer of
management services.

            (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.

            (c) Any other amounts due and owing but unpaid to either
Administrator, Parent and/or their Affiliates or the Group as of



                                       51

<PAGE>   57

the Termination Date shall be paid promptly by the appropriate party.

            (d) Any and all covenants and obligations of either party hereto
which by their terms or by reasonable implication are to be performed, in whole
or in part, after the termination of this Agreement, shall survive such
termination, including, without limitation, the obligations of the parties
pursuant to the following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2,
6.3, 9.5, Article VIII and the applicable provisions of Article X and XI.


                                   ARTICLE XI

                               Dispute Resolution

            Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

            Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means set forth in Section 11.1 and prior to commencing
an arbitration procedure pursuant to this Article XI, the parties shall meet to
discuss and consider other alternative dispute resolution procedures other than
arbitration, provided, however that if the parties hereto agree to an
alternative to arbitration they may agree to an alternative set of rules,
including rules of evidence and procedure. If at any time prior to the rendering
of the decision by the arbitrator (or pursuant to such other alternative dispute
resolution procedure) as contemplated in this Article XI to the extent a party
makes a written offer to the other party proposing a settlement of the



                                       52

<PAGE>   58

matter(s) at issue and such offer is rejected, then the party rejecting such
offer shall be obligated to pay the costs and expenses (excluding the amount of
the award granted under the decision) of the party that offered the settlement
from the date such offer was received by such other party if the decision is for
a dollar amount that is less than the amount of such offer to settle.
Notwithstanding the foregoing, the terms and provisions of this Article XI shall
not preclude any party hereto from seeking, or a court of competent jurisdiction
from granting, a temporary restraining order, temporary injunction or other
equitable relief for any breach of (i) any noncompetition or confidentiality
covenant or (ii) any duty, obligation, covenant, representation or warranty, the
breach of which may cause irreparable harm or damage.

            Section 11.3 Arbitrators. In the event there is a claim,
controversy, dispute or disagreement among Administrator and the Group arising
out of or relating to this Agreement (including any claim based on or arising
from an alleged tort) and the parties hereto have not reached agreement
regarding an alternative to arbitration, the parties agree to select within 30
days of notice by a party to the other of its desire to seek arbitration under
this Article XI one arbitrator mutually acceptable to Administrator and the
Group to hear and decide all such claims under this Article XI. If such matter
or action involves health-care issues, then the arbitrator shall have such
qualifications as would satisfy the requirements of the National Health Lawyers
Association Alternative Dispute Resolution Service. Each of the arbitrators
proposed shall be impartial and independent of all parties. If the parties
cannot agree on the selection of an arbitrator within said 30-day period, then
any party may in writing request the judge of the United States District Court
for the Western District of Texas senior in term of service to appoint the
arbitrator and, subject to this Article XI, such arbitrator shall hear all
arbitration matters arising under this Article XI.

            Section 11.4 Applicable Rules.

            (a) Each arbitration hearing shall be held at a place in San
Antonio, Texas acceptable to the arbitrator. The arbitration shall be conducted
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association to the extent such rules do not conflict with the terms hereof. The
decision of the arbitrator shall be reduced to writing and shall be binding on
the parties and such decision shall contain a concise statement of the reasons
in support of such decision. Judgment upon the award(s) rendered by the
arbitrator may be entered and execution had in any court of competent
jurisdiction or application may be made to such court for a judicial acceptance
of the award and an order of enforcement. The charges and expenses of the
arbitrator shall be shared equally by the parties to the hearing.

            (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of



                                       53

<PAGE>   59

this Article XI. In fulfilling his duties with respect to determining the amount
of any loss, the arbitrator may consider such matters as, in the opinion of the
arbitrator, are necessary or helpful to make a proper valuation. The arbitrator
may consult with and engage disinterested third parties to advise the
arbitrator. The arbitrator shall not add any interest factor reflecting the time
value of money to the amount of any loss and shall not award any punitive
damages.

            (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.

            (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

            (e) All privileges under Texas and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying Texas law.


                                   ARTICLE XII

                               General Provisions

            Section 12.1 Assignment.

            (a) Administrator shall have the right to assign its rights
hereunder to Parent or any direct or indirect wholly-owned subsidiary of
Administrator or Parent (that remains a wholly-owned subsidiary of Administrator
or Parent) or to a financial institution as collateral security for the
indebtedness of Parent, Administrator or their Affiliates without the consent of
the Group. No assignment under subsection (a) shall relieve Administrator or
Parent of their obligations hereunder without the consent of the Group.

            (b) Administrator, Parent and their Affiliates shall provide notice
to the Group of Administrator's intent (i) to assign this Agreement (other than
as permitted in Section 12.1(a) herein), (ii) sell all or substantially all of
the assets of Administrator or (iii) effectuate a consolidation, merger or sale
of a majority of the capital stock of Administrator as soon as practicable
following a decision by the Parent's and Administrator's respective



                                       54

<PAGE>   60

boards of directors to seek such assignment or sale. The assignment of this
Agreement (other than as permitted in Section 12.1(a)), the sale of all or
substantially all of the assets of Administrator by Parent or a consolidation,
merger or sale of a majority of the capital stock of Administrator shall not be
permitted unless Administrator shall give written notice to the Group stating
the party who made the offer and specifying the purchase price offered (the
"Notice"). The Group shall have the option to repurchase the Purchase Assets on
the same terms and conditions set forth in the Notice. In the event the Group
fails to provide written notice to Administrator of its intent to exercise its
option to repurchase the Purchase Assets pursuant to this Section 12.1 within
the earlier of (i) thirty (30) days or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond to an offer following the
Group's receipt of the Notice, the option contained in this Section 12.1 shall
be deemed null and void and of no further force and effect, and Administrator
shall be free to assign the Agreement, sell all or substantially all of the
assets of Administrator or sell or transfer all of the capital stock
Administrator without the consent of the Group. No assignment under this
subsection (b) shall relieve Administrator or Parent of their obligations
hereunder without the consent of the Group.

            Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

            Section 12.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

            Section 12.4 Additional Documents. Each of the parties hereto agrees
to execute any document or documents that may be reasonably requested from time
to time by the other party to implement or complete such party's obligations
pursuant to this Agreement.

            Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,
costs and expenses including, but not limited to, attorney's fees, costs and
expenses for trial, appellate proceedings and negotiations, in addition to any
other relief granted.

            Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or



                                       55

<PAGE>   61

independent legal counsel in such a manner as to indicate that this Agreement or
any provision hereof may be in violation of such laws or regulations, the Group
and Administrator shall amend this Agreement as necessary to preserve the
underlying economic and financial arrangements between the Group and
Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this
Agreement should be construed or deemed, by any governmental authority, agency
or court to constitute the practice of medicine, the performance of said act or
service by Administrator shall be deemed waived and forever unenforceable and
the provisions of this Section 12.6 shall be applicable. Neither party shall
claim or assert illegality as a defense to the enforcement of this Agreement or
any provision hereof; instead, any such purported illegality shall be resolved
pursuant to the terms of this Section 12.6 and Section 12.9.

            Section 12.7 Parties In Interest; No Third Party Beneficiaries.
Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto. Except
as provided in Section 6.1(g), neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party hereto
or thereto any rights or remedies hereunder or thereunder.

            Section 12.8 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

            Section 12.9 Severability. If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

            Section 12.10 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULE GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF TEXAS.

            Section 12.11 No Waiver; Remedies Cumulative. No party hereto shall
by any act (except by written instrument pursuant to Section 12.3 hereof),
delay, indulgence, omission or otherwise be deemed to have waived any right or
remedy hereunder or to have acquiesced in any default in or breach of any of the
terms and conditions hereof. No failure to exercise, nor any delay in
exercising, on the part of any party hereto,. any right, power or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. No
remedy set forth in this Agreement or otherwise conferred upon or reserved to

fails to restore the level of service contemplated by this Agreement in
accordance with such plan submitted or in any event within ninety (90) days, the
Group shall be entitled to reimbursement by Administrator for the reasonable
costs and expenses of obtaining such service on a temporary basis until such
time Administrator demonstrates its ability to perform such service at the level
contemplated by this Agreement. Nothing contained in this subsection (b)(i)
shall be construed to limit the Group's ability to provide notice of a Material
Administrator Default pursuant to Section 10.3(b) of this Agreement.

                  (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service
is construed or deemed to constitute the practice of medicine, Administrator
shall deliver to the Group notice of such an event. The Group shall be entitled
to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

         Section 3.2 General Administrative Services.

         (a) Exclusive Management Services; Scope of Services. Except as
provided in Exhibit 3.2(a), the Group hereby engages Administrator to serve as
its exclusive manager and administrator of non-medical business services
relating to the operation of the Practice, subject to matters reserved for the
Group or referred to the Joint Planning Board as herein contemplated, and
Administrator shall have all necessary authority and hereby agrees to perform
such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

         (b) Billing and Collection.

                  (i) Administrator shall, in the name of and on behalf of the
Group, bill patients, insurance companies, Managed Care Payors, and other
third-party payors and collect all fees for services rendered in connection with
the Practice at the Premises or any Practice Site(s) (including all fees
generated by both the Technical Operations and the Professional Operations), for
services performed outside the Practice for its hospitalized patients, and for
all other professional and Practice services. The Group hereby appoints
Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:


                                       10
<PAGE>   16
                           (A) to bill patients, insurance companies, Managed
Care Payors, and other third-party payors in the Group's name and on its behalf;

                           (B) to collect accounts receivable resulting from
such billing not otherwise purchased by Administrator (as provided for in
Section 3.2(e) hereof) in the Group's name and on its behalf;

                           (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                           (D) to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                           (E) to take possession of and endorse in the name of
the Group and deposit into the Deposit Account (and/or in the name of an
individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                           (F) upon the prior consent of the Group, which
consent shall not be unreasonably withheld or delayed, to initiate the
institution of legal proceedings in the name of the Group or a Physician
Employee to collect any accounts and monies owed to the Group or the Physician
Employee, to enforce the rights of the Group or the Physician Employee, as the
case may be, as creditor under any contract or in connection with the rendering
of any service, and to contest adjustments and denials by governmental agencies
(or their fiscal intermediaries) as third-party payors.

                  (ii) The Group hereby appoints Administrator as its true and
lawful attorney-in-fact to deposit into the Deposit Account all Professional
Revenues and Technical Revenues collected by Administrator as provided for in
this Section 3.2(b). The Group covenants, and shall cause all Physician
Employees and Physician Extender Employees to covenant, to forward any payments
received with respect to any Professional Revenues or Technical Revenues
generated for services provided by the Group or any of its Physician Employees
and Physician Extender Employees to Administrator for deposit. Administrator
shall have the right to withdraw funds from the Deposit Account and all owners
of the Deposit Account shall execute a revocable standing transfer order (the
"Transfer Order") under which the bank maintaining the Deposit Account shall
periodically transfer the entire balance of the Deposit Account to a separate
bank account owned solely by Administrator (the "Administrator Account"). The
Group and Administrator hereby agree to execute from time to time such documents
and instructions as shall be required by the bank maintaining the Deposit
Account and mutually agreed upon to effectuate the foregoing provisions and to
extend or amend such documents and instructions. Any action by the Group that
materially interferes with the operation of this Section, including but not
limited to, any failure to deposit or to have Administrator deposit any


                                       11
<PAGE>   17
Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit Account not authorized by the express
terms of this Agreement or any other written agreement executed by each of the
parties, or any revocation of or attempt to revoke the Transfer Order (otherwise
than upon expiration or termination of this Agreement), will constitute a breach
of this Agreement and will entitle Administrator, in addition to any other
remedies it may have at law or in equity, to seek a court ordered assignment of
the rights provided to Administrator pursuant to subparagraph (i) above.

                  (iii) All monies shall be accounted for by Administrator as
being distinctly attributable to the Group. The Group may perform the functions
or exercise the rights set forth in this Section 3.2(b) only with the prior
written consent of Administrator. The Group shall execute such documents in form
and substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c) Accounting. Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of
the Practice, and Administrator shall perform all bookkeeping and accounting
services necessary or appropriate for the efficient operation of the Practice,
including the maintenance, custody and supervision of business records, ledgers
and reports; the establishment, administration and implementation of accounting
procedures, controls and systems; and implementation and management of
computer-based management information systems. The Group and its authorized
representatives shall have the right to review all financial books and records
maintained by Administrator relating to the operation of the Practice and to the
cash management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the parties have
agreed herein. The purchase price shall be an amount equal to the aggregate face
amount of the accounts receivable being sold less contractual adjustments and


                                       12
<PAGE>   18
estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

         (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication
services and medical transcribing services; provided, however, that the Group
may elect to prepare its own Tax Returns, in which case, the cost of preparing
such Tax Returns in excess of $2,500 per annum shall be included in Excluded
Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group
containing a balance sheet, income statement and monthly operational reports
which detail payments, charges and accounts receivable statistics, monthly
reconciliation reports on cash management and any other financial reports
reasonably requested by a member of the Joint Planning Board designated by the
Group, which shall be delivered to the Group as soon as practicable, but no
later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

         (g) Records and Files.

                  (i) Administrator's Business and Financial Records. At all
times during and after the term of this Agreement, including any extensions or
renewals hereof, all business records, including but not limited to, business
agreements, books of account, personnel records, general administrative records
and all information generated under or contained in the management information
system pertaining to Administrator's obligations hereunder, and other business
information of Administrator of any kind or nature, except for patient medical
records and the Group's Records (as defined in subparagraph (ii) below), shall
be and remain the sole property of Administrator; provided that during and after
termination of this Agreement, the Group shall be entitled to reasonable access
to such records and information, including the right to obtain copies thereof in
any media reasonably requested by the Group, for any purpose related to patient
care or the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years. Administrator hereby agrees
to preserve the confidentiality of such patient medical records and to use the
information in such records only for the limited purposes necessary to perform
management services and, within the limits of its responsibilities hereunder, to
ensure that provision is made for appropriate care for patients of the Practice.


                                       13
<PAGE>   19
                  (ii) The Practice's Business and Financial Records. At all
times during and after the term of this Agreement, the business agreements,
financial, operational, corporate and personnel records and information relating
exclusively to the business and activities of the Group and patient medical
records and charts (hereinafter referred to as the "Group's Records") shall be
and remain the sole property of the Group.

                  (iii) Access to Records. At all times during and after the
term of this Agreement, each party and its authorized agents shall be entitled,
upon request and with reasonable advance notice, to obtain access (within not
more than 30 days following receipt of such notice by the other party or
parties) to all records of the other party directly related to the performance
of such party's obligations pursuant to this Agreement; provided, however, that
such right shall not allow for access to patient, medical and other records that
must be kept confidential as required by law. Either party, at its expense,
shall have the right to make copies in any media of any records to which it has
access pursuant to this subparagraph (iii).

                  (iv) Compliance with Law. The management of all files and
records by Administrator and the Group shall comply with all applicable federal,
state and local statutes and regulations.

         (h) Collections. Subject to the consent requirement contained in
Section 3.2(b)(i)(F), Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees and
pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

         Section 3.3 Facilities.

         (a) Premises. Administrator shall make available to the Group the
Premises that are described in Exhibit 3.3(a) attached hereto and such other
improvements made by Administrator or Parent for the use of the Group hereunder.

all utilities reasonably required in connection with the use of the Premises and
shall provide for the proper cleanliness of the Premises, including normal

waste. Administrator shall maintain the Premises in good condition and make or
cause to be made all necessary repairs thereto.

property necessary or appropriate for the efficient operation of the Practice
acquired by Administrator or Parent (subject to review and approval of the Joint
Planning Board) for the use of the Group pursuant to the terms hereof
(collectively, the "Personal Property"). Administrator shall maintain the
Personal Property in good condition and make or cause to be made all necessary
repairs thereto.


                                       14
<PAGE>   20
         (c) Expenses. All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the
Premises and the Personal Property, including, without limitation, all
reasonably necessary costs of repairs, maintenance and improvements, utility
expenses (i.e., telephone, electric, gas and water), janitorial services, refuse
disposal, real or personal property lease cost payments and expenses, interest,
refinancing expenses, depreciation, loss on disposition of assets, taxes and
casualty, liability and other insurance, shall be included in Practice Expenses.
To the extent the Premises or Personal Property are used in connection with the
Professional Operations, the costs and expenses associated with such usage shall
be allocated between Professional Expenses and Technical Expenses as approved by
the Joint Planning Board.

         (d) Disposition. Subject to provisions contained in existing agreements
to which Administrator or Parent is or becomes a party and, where necessary and
appropriate for the efficient operation of the Practice, nothing herein shall be
construed as precluding Administrator or Parent from selling, leasing or
otherwise disposing of all or any part of the Premises, Personal Property, real
property, improvements, trade names, trademarks and other intangible property;
provided, however, any such sale, lease or disposition shall be subject to the
prior review and approval of the Joint Planning Board and shall not eliminate or
diminish Administrator's obligations hereunder.

         (e) No Warranties or Representations. The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

         Section 3.4 Acquisition and Assistance.

         (a) Employment of Physicians. Subject to consultation with the Joint
Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice. Subject to
consultation with the Joint Planning Board, in the event that a decision is made
by the Group to pursue the employment of selected physicians, if requested by
the Group, Administrator will provide recruiting, consulting, negotiating and
other advisory services in connection with such transaction. Notwithstanding the
preceding, as set forth in and subject to the provisions of Section 4.1 hereof,
the Group shall have complete control of and responsibility for the hiring of
all Physician Employees and Physician Extender Employees.

         (b) Acquisitions. In the event that the Group contemplates acquiring or
affiliating with a physician group, practice or other entity, and such
acquisition or affiliation involves the use or expenditure of Administrator's
and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a
result of such an acquisition or affiliation including, without limitation,
capital and personnel (collectively, the "Resources"), then the Group shall
first consult with the Joint Planning Board and Administrator, and any decision
to make such affiliation or acquisition shall


                                       15
<PAGE>   21
be subject to prior approval of Administrator, which decision of the
Administrator shall be provided to the Group in a reasonable and timely manner
following satisfactory review of the physician group, practice or other entity
to be acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto. If such contemplated acquisition or affiliation does not
involve the use or expenditure of any of Administrator's and/or Parent's
Resources, then such decision shall be in the sole discretion of the Group.
Notwithstanding any provision contained herein to the contrary, any person or
entity with which the Group affiliates or acquires shall be subject to the terms
and conditions of this Agreement. If a decision is made to proceed with any
affiliation or acquisition of a physician group or practice, the Group may seek
from Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

         Section 3.5 Financial Planning and Budgeting.

         (a) Budgeting. Administrator shall collaborate with the Group and the
Joint Planning Board in the preparation of all annual capital and operating
budgets. These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors. For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board. The
projected annual operating budget for each subsequent year shall be subject to
the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice. For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

         (b) Capital Expenditures. Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

                  (i) Budgeted Expenditures. All budgeted capital expenditures
and improvement projects shall be subject to final review and approval by the
Joint Planning Board prior to the making of any actual expenditure. Such review
and approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.


                                       16
<PAGE>   22
                  (ii) Non-Budgeted Expenditures. Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared by
the Joint Planning Board in consultation with the Group and Administrator. All
requests for non-budgeted capital expenditures and improvements at or for the
benefit of the Practice in excess of either $75,000 individually or an aggregate
amount equivalent to $2,500 multiplied by the number of Full-time Physician
Employees employed at the time the capital budget for such Group for the
applicable year is determined (provided, however, that such aggregate amount
shall not exceed $250,000 for any calendar year) must be approved by the Board
of Directors of Parent or by any committee specifically designated by the Board
of Directors of Parent for such purposes.

         (c) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors"). Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning


                                       17
<PAGE>   23
Board, be the responsibility of the Group. Notwithstanding the preceding
language, if a contract or relationship between any Managed Care Payor and the
Group involves or affects a contract or relationship with any other physician
group or practice serviced or managed by Administrator, Parent or any of their
Affiliates (the "Other Practices") and a consensus among the Group and the Other
Practices cannot be reached regarding the contract or relationship, then the
ultimate decision as to the approval, disapproval, termination or amendment of
such contract or relationship involving the Group, the Other Practices and such
Managed Care Payor shall be determined by the affirmative vote of the Physician
Board Members (as defined below) who hold a majority of the Group Voting Power
(as defined below). For purposes of this Section 3.7, (i) the term "Physician
Board Members" shall mean (a) those members appointed by the Group who serve on
the Joint Planning Board and (b) those persons appointed by the Other Practices
who serve on the Other Practices' joint boards (in a similar capacity to the
Joint Planning Board) as part of their contractual relationship with Parent,
Administrator or any of their Affiliates, and (ii) the term "Group Voting Power"
shall mean the total voting percentage which may be cast by the Physician Board
Members on a collective basis, with the percentage of votes able to be cast by
any Group or Other Practice, as applicable, shall be equal to the quotient
determined by dividing (x) the total estimated annual professional revenues to
be generated by the Group from such Managed Care Contract as determined by
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion, by (y) the total estimated annual professional revenues to be
generated by the Group and all Other Practices from such Managed Care Contract
as determined by the Administrator, Parent or their Affiliates, as appropriate,
in its sole discretion.

         Section 3.8 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.9 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and advertising programs shall be
conducted in compliance with applicable standards of medical ethics, laws and
regulations.

<PAGE>   24
         Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program
shall be included in Administrator Expenses; provided, however, that any
expenses related to such program that are incurred for services provided solely
for the direct benefit of the Practice shall be included in Practice Expenses.

         Section 3.11 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by
the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

         Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.


                                   ARTICLE IV

                            Obligations of the Group

         Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender
Employees, and other employees who may have malpractice exposure or liability,

         Section 4.2 Professional Services. The Group shall provide professional
services to its patients in compliance at all times with ethical standards,
laws, rules and regulations applicable to the operations of the Practice, the
Physician Employees and Physician Extender Employees. The Group shall ensure
that each Physician Employee and each Physician Extender Employee has all
required licenses, credentials, approvals or other certifications to perform his
or her duties and services for the Practice and, in the event that the Group
becomes aware of any disciplinary actions or medical malpractice actions
initiated against any Physician Employee or Physician Extender Employee, the
Group shall promptly inform Administrator of such action and the underlying
facts and circumstances. If required by applicable law, any state or federal
regulatory agency or any contractual obligations, the Group shall carry out a
program to monitor the quality of medical care practiced at the Practice;
provided, however, that the preceding language shall not limit the Group's
obligation to participate in or comply with any programs established by
Administrator or Parent for purposes of ensuring that the Group complies with
applicable law. The Group shall employ Physician Employees and Physician
Extender Employees as is necessary to provide efficient medical care to patients
of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery
items on prepaid Managed Care Contracts which are authorized and permitted by
such contracts. A copy of such agreements and any amendment thereto shall be
provided to Administrator for review no later than thirty (30) days prior to the
proposed effective date thereof.

         Section 4.4 Group's Internal Matters. The Group shall be responsible
for matters involving its corporate governance, employees and similar internal
matters, including, but not limited to, preparation and contents of such reports
to regulatory authorities governing the Group that the Group is required by law
to provide, distribution of professional fee income among the Group Physician
Stockholders, disposition of the Group's property and stock (subject to any


                                       20

restrictions contained herein), hiring and firing of its employees, licensing
and implementing all compliance plans and procedures as described in Section
4.6. Except for the expenses attributable to the distribution of professional
fee income among the Group Physician Stockholders, which will be included in
Excluded Practice Expenses, the costs incurred in connection with the foregoing
matters shall be Practice Expenses.

         Section 4.5 Name. Administrator agrees that the Group shall be entitled
to use on a non-exclusive and non-transferable basis for the term of this
Agreement the names set forth on Schedule 4.5 as may be necessary or appropriate
in the performance of the Group's services and obligations hereunder.

         Section 4.6 Compliance with Laws. The Group shall, and shall use its
best efforts to cause the Physician Employees, Physician Extender Employees and
other employees of the Group to, comply with all applicable federal, state and
local laws, rules, regulations and restrictions in the conduct of the Practice's
business. Without limiting the generality of the foregoing, the Group shall
comply and shall cause each Physician Employee, Physician Extender Employee and
other employee of the Group to comply, with all laws applicable to the operation
of the Practice in the generation, transportation, treatment, storage, disposal
or other handling of radioactive, medical, biological or hazardous materials or
waste, and the Group shall not, and shall use its best efforts to prohibit any
Physician Employee, Physician Extender Employee and any employee of the Group

                              Joint Planning Board

         Section 5.1 Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy is counted;
provided, however, that no proxy shall be valid after the expiration of eleven
(11) months from the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2 Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

         (a) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital

the particular project and the Group as a whole.

         (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess
of five percent (5%) to the annual capital or operating budgets.

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

shall review and adopt the fee schedule for all professional services rendered
by the Practice.

         (e) Ancillary Services and Fees. The Joint Planning Board shall approve
Practice-provided non-medical ancillary services (including, without limitation,

upon the pricing, access to, and quality of such services and shall review and
adopt the fee schedule for all ancillary services.

         (f) Provider and Payor Relationships. Subject to Section 3.7, decisions
regarding the establishment or maintenance of relationships with institutional
health care providers and payors shall be approved by the Group after
consultation with the Joint Planning Board.

         (g) Strategic Planning. The Joint Planning Board shall develop a plan

priority of capital expenditures in accordance with Section 3.5(b) hereof.

Board. The Group agrees that, unless the following are approved in advance by
the Joint Planning Board and such act of the Joint Planning Board includes the

this Agreement; (ii) have a material adverse effect on the amount of
Administrator's management fee under Article VII; or (iii) otherwise have a

approved by the members holding at least a majority of the voting power of the
Joint Planning Board. No action of the Joint Planning Board shall be effective
unless authorized by the members holding a majority of the voting power of the
Joint Planning Board present or represented by proxy at the applicable meeting.
In the event that a matter cannot be resolved by the Joint Planning Board due to
a tie vote, and no compromise can be reached, then either (x) the Board of
Directors of Parent or (y) a committee designated by the Board of Directors of
Parent containing at least one (1) physician member will make a final
determination on the matter in dispute provided that both the Group and
Administrator shall have had an opportunity to make a presentation to the Board
of Directors of Parent or a committee thereof, as applicable. A quorum of the
Joint Planning Board shall consist of the members holding a majority of the
voting power of the Joint Planning Board, present in person, by telephone, or by
proxy and the quorum must remain for the duration of the meeting.

         Section 5.4 Joint Planning Board Meetings. Meetings of the Joint
Planning Board may be held by telephone or similar communication equipment so
long as all members participating in a meeting can hear and speak to each other.

(15) business days following each meeting.

         (c) Notice Requirement. A member calling a special meeting must provide
all other members with ten (10) days' advance written or telephonic notice.
Notice must be given or sent to the member's address or telephone number as
shown on the records of the Joint Planning Board. Notice may be delivered
directly to each member or to a person at the member's principal place of
business who would reasonably be expected to communicate that notice promptly to
the member.

         (d) Waiver of Notice Requirement.

                  (i) Written Waiver, Consent or Approval. Notice of a special
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the special meeting. Such waiver,
consent or approval need not specify the purpose of the special meeting. All
such waivers, consents, and approvals shall be filed with the Joint Planning
Board records or made a part of the minutes of the special meetings.

                  (ii) Failure to Object. Notice of special meeting need not be
given to any member who attends the special meeting and does not protest before
or at the commencement of the special meeting such lack of notice.

                  (iii) Quorum. The smallest number of members that hold votes
that exceed fifty percent (50%) of all voting power shall constitute a quorum of
the Joint Planning Board.

                  (iv) Proxies. The Joint Planning Board shall provide for the

agreement upon request, valid under the law of the jurisdiction in which such
agreement is executed, and in a form acceptable to Administrator, Parent and
their Affiliates and its counsel, committing themselves to maintain the
Administrator's Confidential and Proprietary Information in strict confidence
and not to disclose it to any unauthorized person or entity. Upon termination


                                       29
<PAGE>   35
of this Agreement for any reason, the Group and their employees shall cease all
use of any of the Administrator's Confidential and Proprietary Information and
shall execute such documents as may be reasonably necessary to evidence their
abandonment of any claim thereto.

                  (iii) Return of Materials. In the event of any termination of
this Agreement for any reason whatsoever, or at any time upon the request of
Administrator, Parent or their Affiliates, the Group will promptly deliver or
cause to be delivered to Administrator, Parent and their Affiliates all
documents, data and other information in their possession that contains any
Administrator's Confidential and Proprietary Information regarding
Administrator, Parent and their Affiliates. The Group shall not take or retain
any documents or other information, or any reproduction or excerpt thereof,
containing any Administrator's Confidential and Proprietary Information, unless
otherwise authorized in writing by the party possessing such Administrator's
Confidential and Proprietary Information. In the event of termination of this
Agreement, the Group will deliver to Administrator, Parent and their Affiliates
all documents and data pertaining to Administrator's Confidential and
Proprietary Information of the other parties not otherwise purchased as part of
the Purchased Assets.

         (f) Third Party Beneficiaries. The members of the APPI Group not party
to this Agreement are hereby specifically made third party beneficiaries of this
Section 6.1, with the power to enforce the provisions hereof.

         Section 6.2 Restrictive Covenants. The Group shall obtain and enforce
formal agreements with each Physician Employee who is either (i) a Group
Physician Stockholder or (ii), to the extent permitted under applicable law, a
Full-time Physician Employee which each contain certain restrictive covenants
thereof pertaining to covenants not to compete and/or solicit with and not to
divulge the Confidential and Proprietary Information of any member of the APPI
Group or the Practice (the "Restrictive Covenants"). Except as otherwise
approved by the Joint Planning Board, each Group Physician Stockholder or
Full-time Physician Employee shall agree, during the term of his/her employment
or contractor agreement with the Practice and for a period of twenty-four (24)
months after any termination of such agreement: (i) not to establish, operate or
provide professional radiology services at any office, practice, hospital or
health care facility providing services substantially similar to those provided
by the Practice pursuant to this Agreement within 15 miles of any location of
any Practice Site(s) and (ii) to be bound by non-solicitation, noncompetition
and nondisclosure of confidential/proprietary information and engagement of
Administrator covenants similar to those applicable to the Group as contained in
Section 6.1 hereof. Except as otherwise approved by the Joint Planning Board,
each Group Physician Stockholder or Full-time Physician Employee shall agree
that during the term of his/her employment or contractor agreement with the
Group (w) not to practice radiological medicine other than at the Premises or
such other location or Practice Site(s) as approved by the Joint Planning Board;
(x) to devote substantially all of his or her professional time, effort and
ability to the Practice; (y) to request in writing and receive in writing prior
approval from the Joint Planning Board to engage in any outside medical
activities; and (z) to turn over to the Practice, to be included in Professional
Revenues attributed to the Practice, any income derived by such Group Physician
Stockholder or Full-time Physician Employee from any outside medical activity or
related source from the following medically-related activities: teaching,
consulting,


                                       30
<PAGE>   36
medical research, inventions developed utilizing the Group's or the Practice's
time and material, testimony for litigation, and insurance examinations. The
Group shall not materially amend, alter or otherwise change any term or
provision of any Stockholder Employment Agreement or Physician Employee
Employment Agreement relating to the foregoing covenants in this Section 6.2
without the prior written consent of Administrator; notwithstanding the
foregoing, any such amendment, alteration or change shall not be inconsistent
with the terms or provisions of this Agreement. Following termination of this
Agreement, the Group shall not amend, alter or otherwise change any term or
provision of the Restrictive Covenants, unless such provisions are no longer in
force and effect pursuant to the terms of the applicable Stockholder Employment
Agreement or Physician Employee Employment Agreement at the time of termination
of this Agreement. In the event the Purchase Assets are acquired by the Group
pursuant to Article X, the obligation of the Group to enforce Restrictive
Covenants shall be limited to enforcement of non-solicitation and nondisclosure
of confidential/proprietary information covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Stockholder Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Stockholder Employment
Agreements and, to the extent permitted under applicable law, the Physician
Employee Employment Agreements, upon the request of Administrator, the Group
shall assign to Administrator such causes of action and/or other rights it has
related to such breach or default and shall cooperate with and provide
reasonable assistance to Administrator with respect thereto; in which case, all
costs and expenses incurred in connection therewith shall be borne by
Administrator and shall be included in Administrator Expenses, and Administrator
shall be entitled to all damages and other amounts recovered thereby. In the
event the Purchase Assets are acquired by the Group pursuant to Article X, the
obligation of the Group to enforce Restrictive Covenants shall be limited to
enforcement of non-solicitation and nondisclosure of confidential/proprietary
information covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period,


                                       31
<PAGE>   37
scope of activity restricted and/or the geographical area applicable to such
provision of the Restrictive Covenants or this Article VI. The invalidity or
non-enforceability of any provision of the Restrictive Covenants or this Article
VI in any respect shall not affect the validity or enforceability of the
remainder of the Restrictive Covenants or this Article VI or of any other
provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Stockholder or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Stockholder or Full-time Physician Employee from the restrictive
covenants contained in Section 6.2, above. In the event the Group elects to
release such Group Physician Stockholder or Full-time Physician Employee, the
Group hereby covenants that it shall obtain a formal agreement between each
Group Physician Stockholder or Full-time Physician Employee, as the case may be,
and Administrator which provides that, for a period of two (2) years following
termination of any employment agreement with the Group, such Group Physician
Stockholder or Full-time Physician Employee agrees to (a) engage Administrator
as the sole and exclusive manager and administrator of the non-medical functions
and services of said Group Physician Stockholder's or Full-time Physician
Employee's medical practice and (b) pay to Administrator the identical amount
[NY only] of revenues paid by the Group to the Administrator attributable to
such Group Physician Stockholder or Full-time Physician Employee derived from
such Group Physician Stockholder's or Full-time Physician Employee's performance
of professional medical services within 15 miles of any Practice Site.

         Section 6.6 Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary
information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and


                                       32
<PAGE>   38
work effort required and (y) the Group shall not be required to employ any
Radiologist previously associated with such Professional Service Opportunity.

         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half of the time during which the
Administrator, Parent or their Affiliates must respond to an offer described in
the Administrator's Notice, the Group shall deliver to Administrator a written
notice stating whether or not the Group elects to accept or reject the New
Professional Service Opportunity which election shall be binding on the Group.
If the Group does not elect to exercise the right or fails to provide the notice
to Administrator within the time frame herein provided, Administrator shall be
released from the right of first offer with respect to that particular New
Professional Service Opportunity. Prior to consummating any asset acquisition,
merger or other consolidation of any Radiologist, group of Radiologists, or
professional corporation or association (or other professional entity) whose
owners are Radiologists within any Secondary Service Area, Administrator shall
first consult with the Joint Planning Board.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service
Opportunity as contemplated in subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

             "New Professional Service Opportunity" shall mean a Professional

Group managed by Parent, Administrator or their Affiliates is not currently
providing professional Radiology services.

             "Primary Service Area" shall mean that area within a five (5) mile
radius from any imaging center owned, operated or managed by Administrator,
Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.


                                       33
<PAGE>   39
             "Professional Service Opportunity" shall mean any opportunity to

interventional radiology and radiation oncology services.

             "Secondary Service Area" shall mean (i) during the 12-month period
following the Acquisition Effective Date, that area which extends ten (10) miles
beyond the boundary of any Primary Service Area and (ii) during the remaining
term of this Agreement, that area which extends five (5) miles beyond the
boundary of any Primary Service Area.


         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.


                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on


                                       34
<PAGE>   40
Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates based
upon available information for such month, and adjustments to the estimated
payments shall be made to reconcile final amounts due under Section 7.1 on the
next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee


                                       35
<PAGE>   41
and to other related provisions of this Agreement shall be a joint decision of
the parties, shall be memorialized in a written amendment to this Agreement, and
shall be based upon the methodology used to generally determine Services Fees
hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

         (a)      payment of all accrued Practice Expenses for the prior month
                  (subject to the proviso in the preceding sentence;

         (b)      payment of the accrued Service Fee for the prior month;

         (c)      payment of outstanding balance of all amounts advanced to the
                  Group, through the end of the prior month, and applicable
                  interest thereon (as contemplated in Section 7.3); and

         (d)      payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).


                                  ARTICLE VIII

                                     Records

         Section 8.1 Records. All records relating in any way to the operation
of the Practice (other than Group Records) shall, subject to the obligations of
the Practice to maintain patient medical records pursuant to Section 3.2(g), at
all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter, the
Group or its agents shall have reasonable access during normal business hours to
the Group's and Administrator's personnel and financial records relating to the
Practice, including, but not limited to, records of collections, expenses and
disbursements as kept by Administrator in


                                       36
<PAGE>   42
performing Administrator's obligations under this Agreement, and the Group may
copy any or all such records.


                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1 Insurance to be Maintained by the Group.

         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.


                                       37
<PAGE>   43
         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.

         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5 Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its shareholders, employees
and/or subcontractors (other than Administrator, Parent, Affiliates or their
employees, officers, directors, agents, attorneys and consultants) during the
term of this Agreement. Provided, however, that in the event an indemnification
obligation under the preceding sentence arises as of the result of any act or
omission of a person who is an officer, shareholder or other equity holder,
director, employee, agent, attorney or consultant of Administrator, Parent or
any of their Affiliates (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
the Group's indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or
incurred, that are caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts or omissions by Administrator, Parent or Affiliates and/or any of
their respective shareholders, employees and/or subcontractors (other than the
Group or its employees) during the term of this Agreement. Provided, however
that


                                       38
<PAGE>   44
in the event an indemnification obligation under the preceding sentence arises
as a result of any act or omission of a person who is an officer, shareholder or
other equity holder, director, employee, agent, attorney or consultant of the
Group (other than in connection with the activities of the Joint Planning
Board), such person shall not be entitled to indemnification in connection
therewith and any other adjustment as is equitable shall be made to
Administrator's or Parent's indemnification obligation arising thereby.

Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not


                                       39
<PAGE>   45
the obligation, to cure any Material Adminstrator Default. Notwithstanding
anything to the contrary in this Agreement, following receipt by Administrator
of the notice of a Material Administrator Default and until such Material
Administrator Default shall be cured, the Group may take such action as may be
reasonably required to cover such Material Administrator Default so as to
maintain for the Group the same level of service as before the Material
Administrator Default, without prejudicing in any way the Group's other rights
and remedies, and may offset all of its costs from the amounts which may
otherwise be due to Administrator under this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that


                                       40
<PAGE>   46
individual from participating in or from receiving reimbursement under any
program funded by the federal government or by any state government,
notwithstanding any available post-sanction remedies, or (4) is otherwise
disciplined by any licensing, regulatory or professional entity or institution,
the result of any of which event does or is reasonably expected to materially
adversely affect the Practice, the result of any of which event described in
subparagraphs (1) through (4) above, in the absence of termination of a
Physician Employee or a Physician Extender Employee or other action of the Group
to monitor and cure such act or conduct by such employee, does or reasonably
would be expected to materially and adversely affect the Practice or the Group.
Notwithstanding anything to the contrary in this Agreement, following receipt by
the Group of the notice of a Material Group Default, and until such Material
Group Default shall be cured, the Administrator may take such action as may be
reasonably required to cover such Material Group Default so as to maintain for
the Administrator the same level of service at the Premises as before the
Material Group Default, without prejudicing in any way Administrator other
rights and remedies, and may offset all of its costs of cover from amounts which
may otherwise due to the Group under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Stockholders and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
(with the exception of Hector Correa, Nancy Sussman, M.D., or Herbert Z. Geller)
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee [or Physician Extender Employee] that intends to
retire prior to expiration of such five-year period, then such Physician
Employee or Physician Extender Employee shall not be counted for purposes of
determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator and/or Parent, the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or their
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's or their Affiliates' accounting and financial records (the "Purchase
Assets"), including, but not limited to, without duplication, (i) all equipment,
furniture, fixtures, furnishings, inventory, supplies, improvements, additions
and leasehold improvements utilized by the Practice, (ii) any real estate owned
by Administrator, Parent or Affiliates that is occupied by or used primarily for
the benefit of the Practice, (iii) all unamortized intangible assets (including,
without limitation, goodwill) set forth on the financial statements of
Administrator, Parent or their Affiliates used solely in connection with the
Practice or otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and their Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c) Purchase Price. The Purchase Price shall be the lesser of (i) Fair
Market Value of the Purchase Assets subject to the assumption of the Practice
Related Liabilities or (ii) the value of the Actual Consideration (defined
below)(alternatively, the "Purchase Price"); provided, however, the Purchase
Price shall not be less than the net book value of the Purchase Assets at the
Termination Date. The Purchase Price shall be paid pursuant to Section 10.7. For
purposes of this subparagraph (c), the term "Actual Consideration" shall mean
(i) cash consideration paid to the Group pursuant to the Acquisition Agreement
and (2) an amount equal to the number of shares of Parent Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, reorganizations,
or any similar transaction whereby the Parent Common Stock is increased or
decreased or exchanged for a different number or kind of securities) issued
pursuant to the Acquisition Agreement multiplied by the fair market value of
Parent Common Stock immediately prior to the time that a Termination Notice is
provided pursuant to Section 10.7. The Purchase Price shall be appropriately
adjusted to offset and account for any monetary obligations of the Group or
Administrator owing to the other as provided herein.


                                       42

         (d) Exercise of Option.

                  (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                  (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

         (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at the Purchase Closing, Administrator and/or its Affiliates, as the case
may be, shall transfer and assign the Purchase Assets to the Group, and in
consideration therefor, the Group shall (a) pay to Administrator, Parent and/or
their Affiliates an amount in cash or, at the option of the Group (subject to
the conditions set forth below), Parent Common Stock (valued pursuant to Section
10.6(c) hereof), or some combination of cash and Parent Common Stock equal to
the Purchase Price and (b) assume the Practice Related Liabilities. The
structure of the transaction set forth in this Section 10.7 shall, if possible,
be structured as a tax-free transaction under applicable law. Each party shall
execute such documents or instruments as are reasonably necessary, in the
opinion of each party and its counsel, to effect the foregoing transaction. The
Group shall, and shall use its best efforts to cause each shareholder of the
Group to, execute such documents or instruments as may be necessary to cause the
Group to assume the Practice Related Liabilities and to release Administrator,
Parent and/or their Affiliates, as the case may be, from any liability or
obligation with respect thereto. In the event the Group desires to pay all or a
portion of the Purchase Price in shares of Parent Common Stock, such transaction
shall be subject to the satisfaction of each of the following conditions:


                                       43
<PAGE>   49
         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims, proxies, options, stockholders' agreements
and encumbrances (not including any applicable securities restrictions and
lock-up arrangements with the Parent or any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain financing for such acquisition but is unable to
obtain such financing and (iii) there is either a Material Administrator Default
pursuant to Section 10.3(a) or (c) or a Material Group Default pursuant to
Section 10.4(b) triggering a sale of the Purchase Assets, the Group shall be
entitled to obtain financing from Administrator, Parent and/or their Affiliates
but only for the difference between the Fair Market Value of the Purchase Assets
and the net book value of the Purchase Assets. The terms of such financing shall
be for a five (5) year period at an interest rate equal to the prime rate (as
published in the Wall Street Journal) plus four percent (4%) or such lesser rate
as is required to be in conformance with all applicable state and federal law.
In the event the Group is entitled to obtain financing from Administrator,
Parent and/or their Affiliates, the Group shall execute and deliver to
Administrator, Parent and/or their Affiliates all such documentation necessary
and appropriate to effectuate the financing transaction including, without
limitation, a secured promissory note, security agreement and financing
statements and such documentation shall contain such representations, warranties
and conditions customary to a secured transaction of this size.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator, Parent and/or their Affiliates to the
Group or the Group to the Administrator, Parent and/or their Affiliates


                                       44
<PAGE>   50
(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

         (a) Administrator, Parent and/or their Affiliates shall use their best
efforts to cooperate with the Group for the appropriate transfer of management
services.

         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.

         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.


                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

         Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means


                                       45
<PAGE>   51
set forth in Section 11.1 and prior to commencing an arbitration procedure
pursuant to this Article XI, the parties shall meet to discuss and consider
other alternative dispute resolution procedures other than arbitration,
provided, however that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including rules of
evidence and procedure. If at any time prior to the rendering of the decision by
the arbitrator (or pursuant to such other alternative dispute resolution
procedure) as contemplated in this Article XI to the extent a party makes a
written offer to the other party proposing a settlement of the matter(s) at
issue and such offer is rejected, then the party rejecting such offer shall be
obligated to pay the costs and expenses (excluding the amount of the award
granted under the decision) of the party that offered the settlement from the
date such offer was received by such other party if the decision is for a dollar
amount that is less than the amount of such offer to settle. Notwithstanding the
foregoing, the terms and provisions of this Article XI shall not preclude any
party hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

         Section 11.3 Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among Administrator and the Group arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within 30 days of notice
by a party to the other of its desire to seek arbitration under this Article XI
one arbitrator mutually acceptable to Administrator and the Group to hear and
decide all such claims under this Article XI. If such matter or action involves
health-care issues, then the arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators proposed shall be impartial
and independent of all parties. If the parties cannot agree on the selection of
an arbitrator within said 30-day period, then any party may in writing request
the judge of the United States District Court for the Southern District of New
York (White Plains) senior in term of service to appoint the arbitrator and,
subject to this Article XI, such arbitrator shall hear all arbitration matters
arising under this Article XI.

         Section 11.4 Applicable Rules.

         (a) Each arbitration hearing shall be held at a place in Weschester or
Rockland Counties, New York, acceptable to the arbitrator. The arbitration shall
be conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof. The decision of the arbitrator shall be reduced to writing and shall be
binding on the parties and such decision shall contain a concise statement of
the reasons in support of such decision. Judgment upon the award(s) rendered by
the arbitrator may be entered and execution had in any court of competent
jurisdiction or application may be made to such court for a judicial acceptance
of the award and an order of enforcement. The charges and expenses of the
arbitrator shall be shared equally by the parties to the hearing.


                                       46
<PAGE>   52
         (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI. In
fulfilling his duties with respect to determining the amount of any loss, the
arbitrator may consider such matters as, in the opinion of the arbitrator, are
necessary or helpful to make a proper valuation. The arbitrator may consult with
and engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

         (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.

         (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e) All privileges under New York and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying New York law.


                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment.

         (a) Administrator shall have the right to assign its rights hereunder
to Parent or any direct or indirect wholly-owned subsidiary of Administrator or
Parent (that remains a wholly-owned subsidiary of Administrator or Parent) or to
a financial institution as collateral security for the indebtedness of Parent,
Administrator or their Affiliates without the consent of the Group. No
assignment under subsection (a) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         (b) Administrator, Parent and their Affiliates shall provide notice to
the Group of Administrator's intent (i) to assign this Agreement (other than as
permitted in Section 12.1(a) herein), (ii) sell all or substantially all of the
assets of Administrator or (iii) effectuate a consolidation, merger or sale of a
majority of the capital stock of Administrator as soon as practicable following
a decision by the Parent's and Administrator's respective boards of directors to
seek such assignment or sale. The assignment of this Agreement (other than as
permitted in Section 12.1(a)), the sale of all or substantially all of the
assets of Administrator by Parent or a consolidation, merger or sale of a
majority of the capital stock of Administrator


                                       47
<PAGE>   53
shall not be permitted unless Administrator shall give written notice to the
Group stating the party who made the offer and specifying the purchase price
offered (the "Notice"). The Group shall have the option to repurchase the
Purchase Assets on the same terms and conditions set forth in the Notice. In the
event the Group fails to provide written notice to Administrator of its intent
to exercise its option to repurchase the Purchase Assets pursuant to this
Section 12.1 within the earlier of (i) thirty (30) days or (ii) one-half of the
time during which Administrator, Parent or their Affiliates must respond to an
offer following the Group's receipt of the Notice, the option contained in this
Section 12.1 shall be deemed null and void and of no further force and effect,
and Administrator shall be free to assign the Agreement, sell all or
substantially all of the assets of Administrator or sell or transfer all of the
capital stock Administrator without the consent of the Group. No assignment
under this subsection (b) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

         Section 12.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 12.4 Additional Documents. Each of the parties hereto agrees to
execute any document or documents that may be reasonably requested from time to
time by the other party to implement or complete such party's obligations
pursuant to this Agreement.

         Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,
costs and expenses including, but not limited to, attorney's fees, costs and
expenses for trial, appellate proceedings and negotiations, in addition to any
other relief granted.

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group
and Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this
Agreement should be construed or deemed, by any governmental authority, agency

for the services set forth in this Article III, and the costs, fees, expenses
and other disbursements incurred by Administrator or Parent in connection
therewith shall be included in Practice Expenses, except to the extent such

hereunder as is necessary or appropriate for the efficient operation of the
Practice, including, without limitation, performance of some of the business

perform its services hereunder. Administrator shall cause its employees, to
comply with all applicable federal, state and local laws, rules and regulations
in Administrator's provision of services hereunder.

costs and expenses of obtaining such service on a temporary basis until such
time Administrator demonstrates its ability to perform such service at the level
contemplated by this Agreement. Nothing contained in this subsection (b)(i)

Administrator Default pursuant to Section 10.3(b) of this Agreement.

                  (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service
is construed or deemed to constitute the practice of medicine, Administrator
shall deliver to the Group notice of such an event. The Group shall be entitled
to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

attorney-in-fact, for the following purposes:

3.2(e) hereof) in the Group's name and on its behalf;

                         (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                         (D) to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                         (E) to take possession of and endorse in the name of
the Group and deposit into the Deposit Account (and/or in the name of an
individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                         (F) upon the prior consent of the Group, which consent
shall not be unreasonably withheld or delayed, to initiate the institution of
legal proceedings in the name of the Group or a Physician Employee to collect
any accounts and monies owed to the Group or the Physician Employee, to enforce
the rights of the Group or the Physician Employee, as the case may be, as
creditor under any contract or in connection with the rendering of any service,
and to contest adjustments and denials by governmental agencies (or their fiscal
intermediaries) as third-party payors.

                  (ii) The Group hereby appoints Administrator as its true and
lawful attorney-in-fact to deposit into the Deposit Account all Professional
Revenues and Technical Revenues collected by Administrator as provided for in
this Section 3.2(b). The Group covenants, and shall cause all Physician
Employees and Physician Extender Employees to covenant, to forward any payments
received with respect to any Professional Revenues or Technical Revenues
generated for services provided by the Group or any of its Physician Employees
and Physician Extender Employees to Administrator for deposit. Administrator
shall have the right to withdraw funds from the Deposit Account and all owners
of the Deposit Account shall execute a revocable standing transfer order (the
"Transfer Order") under which the bank maintaining the Deposit Account shall
periodically transfer the entire balance of the Deposit Account to a separate
bank account owned solely by Administrator (the "Administrator Account"). The
Group and Administrator hereby agree to execute from time to time such documents
and instructions as shall be required by the bank maintaining the Deposit
Account and mutually agreed upon to effectuate the foregoing provisions and to
extend or amend such documents and instructions. Any action by the Group that
materially interferes with the operation of this Section, including but not
limited to, any failure to deposit or to have Administrator deposit any


                                       11
<PAGE>   17

Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit Account not authorized by the express
terms of this Agreement or any other written agreement executed by each of the
parties, or any revocation of or attempt to revoke the Transfer Order (otherwise
than upon expiration or termination of this Agreement), will constitute a breach
of this Agreement and will entitle Administrator, in addition to any other
remedies it may have at law or in equity, to seek a court ordered assignment of
the rights provided to Administrator pursuant to subparagraph (i) above.

                  (iii) All monies shall be accounted for by Administrator as
being distinctly attributable to the Group. The Group may perform the functions
or exercise the rights set forth in this Section 3.2(b) only with the prior
written consent of Administrator. The Group shall execute such documents in form
and substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c) Accounting. Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of
the Practice, and Administrator shall perform all bookkeeping and accounting
services necessary or appropriate for the efficient operation of the Practice,
including the maintenance, custody and supervision of business records, ledgers
and reports; the establishment, administration and implementation of accounting
procedures, controls and systems; and implementation and management of
computer-based management information systems. The Group and its authorized
representatives shall have the right to review all financial books and records
maintained by Administrator relating to the operation of the Practice and to the
cash management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the parties have
agreed herein. The purchase price shall be an amount equal to the aggregate face
amount of the accounts receivable being sold less contractual adjustments and


                                       12
<PAGE>   18

estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

         (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication
services and medical transcribing services; provided, however, that the Group
may elect to prepare its own Tax Returns, in which case, the cost of preparing
such Tax Returns in excess of $2,500 per annum shall be included in Excluded
Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group
containing a balance sheet, income statement and monthly operational reports
which detail payments, charges and accounts receivable statistics, monthly
reconciliation reports on cash management and any other financial reports
reasonably requested by a member of the Joint Planning Board designated by the
Group, which shall be delivered to the Group as soon as practicable, but no
later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

         (g)      Records and Files.

                  (i) Administrator's Business and Financial Records. At all
times during and after the term of this Agreement, including any extensions or
renewals hereof, all business records, including but not limited to, business
agreements, books of account, personnel records, general administrative records
and all information generated under or contained in the management information
system pertaining to Administrator's obligations hereunder, and other business
information of Administrator of any kind or nature, except for patient medical
records and the Group's Records (as defined in subparagraph (ii) below), shall
be and remain the sole property of Administrator; provided that during and after
termination of this Agreement, the Group shall be entitled to reasonable access
to such records and information, including the right to obtain copies thereof in
any media reasonably requested by the Group, for any purpose related to patient
care or the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years. Administrator hereby agrees
to preserve the confidentiality of such patient medical records and to use the
information in such records only for the limited purposes necessary to perform
management services and, within the limits of its responsibilities hereunder, to
ensure that provision is made for appropriate care for patients of the Practice.

times during and after the term of this Agreement, the business agreements,
financial, operational, corporate and personnel records and information relating
exclusively to the business and activities of the Group and patient medical
records and charts (hereinafter referred to as the "Group's Records") shall be

                  (iii) Access to Records. At all times during and after the
term of this Agreement, each party and its authorized agents shall be entitled,
upon request and with reasonable advance notice, to obtain access (within not
more than 30 days following receipt of such notice by the other party or
parties) to all records of the other party directly related to the performance
of such party's obligations pursuant to this Agreement; provided, however, that
such right shall not allow for access to patient, medical and other records that
must be kept confidential as required by law. Either party, at its expense,
shall have the right to make copies in any media of any records to which it has
access pursuant to this subparagraph (iii).

                  (iv) Compliance with Law. The management of all files and
records by Administrator and the Group shall comply with all applicable federal,
state and local statutes and regulations.

         (h) Collections. Subject to the consent requirement contained in
Section 3.2(b)(i)(F), Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees and
pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

         Section 3.3         Facilities.

Premises that are described in Exhibit 3.3(a) attached hereto and such other

property necessary or appropriate for the efficient operation of the Practice
acquired by Administrator or Parent (subject to review and approval of the Joint

repairs thereto.


                                       14
<PAGE>   20

         (c) Expenses. All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the
Premises and the Personal Property, including, without limitation, all
reasonably necessary costs of repairs, maintenance and improvements, utility
expenses (i.e., telephone, electric, gas and water), janitorial services, refuse
disposal, real or personal property lease cost payments and expenses, interest,
refinancing expenses, depreciation, loss on disposition of assets, taxes and

To the extent the Premises or Personal Property are used in connection with the
Professional Operations, the costs and expenses associated with such usage shall
be allocated between Professional Expenses and Technical Expenses as approved by
the Joint Planning Board.

         (d) Disposition. Subject to provisions contained in existing agreements
to which Administrator or Parent is or becomes a party and, where necessary and
appropriate for the efficient operation of the Practice, nothing herein shall be
construed as precluding Administrator or Parent from selling, leasing or
otherwise disposing of all or any part of the Premises, Personal Property, real
property, improvements, trade names, trademarks and other intangible property;
provided, however, any such sale, lease or disposition shall be subject to the
prior review and approval of the Joint Planning Board and shall not eliminate or
diminish Administrator's obligations hereunder.

         (e) No Warranties or Representations. The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

         Section 3.4         Acquisition and Assistance.

         (a) Employment of Physicians. Subject to consultation with the Joint
Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice. Subject to
consultation with the Joint Planning Board, in the event that a decision is made
by the Group to pursue the employment of selected physicians, if requested by
the Group, Administrator will provide recruiting, consulting, negotiating and
other advisory services in connection with such transaction. Notwithstanding the
preceding, as set forth in and subject to the provisions of Section 4.1 hereof,
the Group shall have complete control of and responsibility for the hiring of
all Physician Employees and Physician Extender Employees.

         (b) Acquisitions. In the event that the Group contemplates acquiring or
affiliating with a physician group, practice or other entity, and such
acquisition or affiliation involves the use or expenditure of Administrator's
and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a
result of such an acquisition or affiliation including, without limitation,
capital and personnel (collectively, the "Resources"), then the Group shall
first consult with the Joint Planning Board and Administrator, and any decision
to make such affiliation or acquisition shall


                                       15
<PAGE>   21

be subject to prior approval of Administrator, which decision of the
Administrator shall be provided to the Group in a reasonable and timely manner
following satisfactory review of the physician group, practice or other entity
to be acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto. If such contemplated acquisition or affiliation does not
involve the use or expenditure of any of Administrator's and/or Parent's
Resources, then such decision shall be in the sole discretion of the Group.
Notwithstanding any provision contained herein to the contrary, any person or
entity with which the Group affiliates or acquires shall be subject to the terms
and conditions of this Agreement. If a decision is made to proceed with any
affiliation or acquisition of a physician group or practice, the Group may seek
from Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

         Section 3.5         Financial Planning and Budgeting.

         (a) Budgeting. Administrator shall collaborate with the Group and the
Joint Planning Board in the preparation of all annual capital and operating
budgets. These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors. For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board. The
projected annual operating budget for each subsequent year shall be subject to
the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice. For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

        (b) Capital Expenditures. Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

                  (i) Budgeted Expenditures. All budgeted capital expenditures
and improvement projects shall be subject to final review and approval by the
Joint Planning Board prior to the making of any actual expenditure. Such review
and approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.


                                       16
<PAGE>   22

                  (ii) Non-Budgeted Expenditures. Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared by
the Joint Planning Board in consultation with the Group and Administrator. All
requests for non-budgeted capital expenditures and improvements at or for the
benefit of the Practice in excess of either $75,000 individually or an aggregate
amount equivalent to $2,500 multiplied by the number of Full-time Physician
Employees employed at the time the capital budget for such Group for the
applicable year is determined (provided, however, that such aggregate amount
shall not exceed $250,000 for any calendar year) must be approved by the Board
of Directors of Parent or by any committee specifically designated by the Board
of Directors of Parent for such purposes.

         (c) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors"). Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning


                                       17
<PAGE>   23

Board, be the responsibility of the Group. Notwithstanding the preceding
language, if a contract or relationship between any Managed Care Payor and the
Group involves or affects a contract or relationship with any other physician
group or practice serviced or managed by Administrator, Parent or any of their
Affiliates (the "Other Practices") and a consensus among the Group and the Other
Practices cannot be reached regarding the contract or relationship, then the
ultimate decision as to the approval, disapproval, termination or amendment of
such contract or relationship involving the Group, the Other Practices and such
Managed Care Payor shall be determined by the affirmative vote of the Physician
Board Members (as defined below) who hold a majority of the Group Voting Power
(as defined below). For purposes of this Section 3.7, (i) the term "Physician
Board Members" shall mean (a) those members appointed by the Group who serve on
the Joint Planning Board and (b) those persons appointed by the Other Practices
who serve on the Other Practices' joint boards (in a similar capacity to the
Joint Planning Board) as part of their contractual relationship with Parent,
Administrator or any of their Affiliates, and (ii) the term "Group Voting Power"
shall mean the total voting percentage which may be cast by the Physician Board
Members on a collective basis, with the percentage of votes able to be cast by
any Group or Other Practice, as applicable, shall be equal to the quotient
determined by dividing (x) the total estimated annual professional revenues to
be generated by the Group from such Managed Care Contract as determined by
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion, by (y) the total estimated annual professional revenues to be
generated by the Group and all Other Practices from such Managed Care Contract
as determined by the Administrator, Parent or their Affiliates, as appropriate,
in its sole discretion.

         Section 3.8 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.9 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and advertising programs shall be
conducted in compliance with applicable standards of medical ethics, laws and
regulations.

         Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program
shall be included in Administrator Expenses; provided, however, that any
expenses related to such program that are incurred for services provided solely
for the direct benefit of the Practice shall be included in Practice Expenses.

         Section 3.11 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by
the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

         Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.


                                   ARTICLE IV

                            Obligations of the Group

         Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender
Employees, and other employees who may have malpractice exposure or liability,
are insurable and by participating in an ongoing risk management program.


                                       19
<PAGE>   25

         Section 4.2 Professional Services. The Group shall provide professional
services to its patients in compliance at all times with ethical standards,
laws, rules and regulations applicable to the operations of the Practice, the
Physician Employees and Physician Extender Employees. The Group shall ensure
that each Physician Employee and each Physician Extender Employee has all
required licenses, credentials, approvals or other certifications to perform his
or her duties and services for the Practice and, in the event that the Group
becomes aware of any disciplinary actions or medical malpractice actions
initiated against any Physician Employee or Physician Extender Employee, the
Group shall promptly inform Administrator of such action and the underlying
facts and circumstances. If required by applicable law, any state or federal
regulatory agency or any contractual obligations, the Group shall carry out a
program to monitor the quality of medical care practiced at the Practice;
provided, however, that the preceding language shall not limit the Group's
obligation to participate in or comply with any programs established by
Administrator or Parent for purposes of ensuring that the Group complies with
applicable law. The Group shall employ Physician Employees and Physician
Extender Employees as is necessary to provide efficient medical care to patients
of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery
items on prepaid Managed Care Contracts which are authorized and permitted by
such contracts. A copy of such agreements and any amendment thereto shall be
provided to Administrator for review no later than thirty (30) days prior to the
proposed effective date thereof.

         Section 4.4 Group's Internal Matters. The Group shall be responsible
for matters involving its corporate governance, employees and similar internal
matters, including, but not limited to, preparation and contents of such reports
to regulatory authorities governing the Group that the Group is required by law

         Section 5.1  Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy is counted;
provided, however, that no proxy shall be valid after the expiration of eleven
(11) months from the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2  Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

regarding the establishment or maintenance of relationships with institutional

a tie vote, and no compromise can be reached, then either (x) the Board of
Directors of Parent or (y) a committee designated by the Board of Directors of
Parent containing at least one (1) physician member will make a final
determination on the matter in dispute provided that both the Group and
Administrator shall have had an opportunity to make a presentation to the Board
of Directors of Parent or a committee thereof, as applicable. A quorum of the

meeting need not be given to any member who, either before or after the meeting,

such other location or Practice Site(s) as approved by the Joint Planning Board;
(x) to devote substantially all of his or her professional time, effort and
ability to the Practice; (y) to request in writing and receive in writing prior
approval from the Joint Planning Board to engage in any outside medical
activities; and (z) to turn over to the Practice, to be included in Professional
Revenues attributed to the Practice, any income derived by such Group Physician
Stockholder or Full-time Physician Employee from any outside medical activity or
related source from the following medically-related activities: teaching,
consulting,


                                       30

medical research, inventions developed utilizing the Group's or the Practice's
time and material, testimony for litigation, and insurance examinations. The
Group shall not materially amend, alter or otherwise change any term or
provision of any Stockholder Employment Agreement or Physician Employee
Employment Agreement relating to the foregoing covenants in this Section 6.2
without the prior written consent of Administrator; notwithstanding the
foregoing, any such amendment, alteration or change shall not be inconsistent
with the terms or provisions of this Agreement. Following termination of this
Agreement, the Group shall not amend, alter or otherwise change any term or
provision of the Restrictive Covenants, unless such provisions are no longer in
force and effect pursuant to the terms of the applicable Stockholder Employment
Agreement or Physician Employee Employment Agreement at the time of termination
of this Agreement. In the event the Purchase Assets are acquired by the Group
pursuant to Article X, the obligation of the Group to enforce Restrictive
Covenants shall be limited to enforcement of non-solicitation and nondisclosure
of confidential/proprietary information covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Stockholder Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Stockholder Employment
Agreements and, to the extent permitted under applicable law, the Physician
Employee Employment Agreements, upon the request of Administrator, the Group
shall assign to Administrator such causes of action and/or other rights it has
related to such breach or default and shall cooperate with and provide
reasonable assistance to Administrator with respect thereto; in which case, all
costs and expenses incurred in connection therewith shall be borne by
Administrator and shall be included in Administrator Expenses, and Administrator
shall be entitled to all damages and other amounts recovered thereby. In the
event the Purchase Assets are acquired by the Group pursuant to Article X, the
obligation of the Group to enforce Restrictive Covenants shall be limited to
enforcement of non-solicitation and nondisclosure of confidential/proprietary
information covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period,


                                       31
<PAGE>   37

scope of activity restricted and/or the geographical area applicable to such
provision of the Restrictive Covenants or this Article VI. The invalidity or
non-enforceability of any provision of the Restrictive Covenants or this Article
VI in any respect shall not affect the validity or enforceability of the
remainder of the Restrictive Covenants or this Article VI or of any other
provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Stockholder or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Stockholder or Full-time Physician Employee from the restrictive
covenants contained in Section 6.2, above. In the event the Group elects to
release such Group Physician Stockholder or Full-time Physician Employee, the
Group hereby covenants that it shall obtain a formal agreement between each
Group Physician Stockholder or Full-time Physician Employee, as the case may be,
and Administrator which provides that, for a period of two (2) years following
termination of any employment agreement with the Group, such Group Physician
Stockholder or Full-time Physician Employee agrees to (a) engage Administrator
as the sole and exclusive manager and administrator of the non-medical functions
and services of said Group Physician Stockholder's or Full-time Physician
Employee's medical practice and (b) pay to Administrator the identical amount
[NY only] of revenues paid by the Group to the Administrator attributable to
such Group Physician Stockholder or Full-time Physician Employee derived from
such Group Physician Stockholder's or Full-time Physician Employee's performance
of professional medical services within 15 miles of any Practice Site.

         Section 6.6 Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary
information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and


                                       32
<PAGE>   38

work effort required and (y) the Group shall not be required to employ any
Radiologist previously associated with such Professional Service Opportunity.

         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half of the time during which the
Administrator, Parent or their Affiliates must respond to an offer described in
the Administrator's Notice, the Group shall deliver to Administrator a written
notice stating whether or not the Group elects to accept or reject the New
Professional Service Opportunity which election shall be binding on the Group.
If the Group does not elect to exercise the right or fails to provide the notice
to Administrator within the time frame herein provided, Administrator shall be
released from the right of first offer with respect to that particular New
Professional Service Opportunity. Prior to consummating any asset acquisition,
merger or other consolidation of any Radiologist, group of Radiologists, or
professional corporation or association (or other professional entity) whose
owners are Radiologists within any Secondary Service Area, Administrator shall
first consult with the Joint Planning Board.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service Opportunity as contemplated in 
subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

                  "New Professional Service Opportunity" shall mean a
Professional Service Opportunity pursuant to which the Group or any other member
of an APPI Group managed by Parent, Administrator or their Affiliates is not
currently providing professional Radiology services.

                  "Primary Service Area" shall mean that area within a five (5)
mile radius from any imaging center owned, operated or managed by Administrator,
Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.


                                       33
<PAGE>   39

                  "Professional Service Opportunity" shall mean any opportunity
to perform professional Radiology services for any hospital, hospital system or
imaging center under a formal agreement with such entity.

                  "Radiologist" shall mean and include both radiologists and 
radiation oncologists.

                  "Radiology" shall mean and include diagnostic imaging,
interventional radiology and radiation oncology services.

                  "Secondary Service Area" shall mean (i) during the 12-month
period following the Acquisition Effective Date, that area which extends ten
(10) miles beyond the boundary of any Primary Service Area and (ii) during the
remaining term of this Agreement, that area which extends five (5) miles beyond
the boundary of any Primary Service Area.

         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.


                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on


                                       34
<PAGE>   40

Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates based
upon available information for such month, and adjustments to the estimated
payments shall be made to reconcile final amounts due under Section 7.1 on the
next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee


                                       35
<PAGE>   41

and to other related provisions of this Agreement shall be a joint decision of
the parties, shall be memorialized in a written amendment to this Agreement, and
shall be based upon the methodology used to generally determine Services Fees
hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

         (a)      payment of all accrued Practice Expenses for the prior month 
                  (subject to the proviso in the preceding sentence;

         (b)      payment of the accrued Service Fee for the prior month;

         (c)      payment of outstanding balance of all amounts advanced to the 
                  Group, through the end of the prior month, and applicable
                  interest thereon (as contemplated in Section 7.3); and

         (d)      payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).


                                  ARTICLE VIII

                                     Records

         Section 8.1 Records. All records relating in any way to the operation
of the Practice (other than Group Records) shall, subject to the obligations of
the Practice to maintain patient medical records pursuant to Section 3.2(g), at
all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter, the
Group or its agents shall have reasonable access during normal business hours to
the Group's and Administrator's personnel and financial records relating to the
Practice, including, but not limited to, records of collections, expenses and
disbursements as kept by Administrator in


                                       36
<PAGE>   42

performing Administrator's obligations under this Agreement, and the Group may
copy any or all such records.


                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1  Insurance to be Maintained by the Group.

         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.

                                       37
<PAGE>   43

         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.

         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5  Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its shareholders, employees
and/or subcontractors (other than Administrator, Parent, Affiliates or their
employees, officers, directors, agents, attorneys and consultants) during the
term of this Agreement. Provided, however, that in the event an indemnification
obligation under the preceding sentence arises as of the result of any act or
omission of a person who is an officer, shareholder or other equity holder,
director, employee, agent, attorney or consultant of Administrator, Parent or
any of their Affiliates (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
the Group's indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or
incurred, that are caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts or omissions by Administrator, Parent or Affiliates and/or any of
their respective shareholders, employees and/or subcontractors (other than the
Group or its employees) during the term of this Agreement. Provided, however
that

                                       38
<PAGE>   44

in the event an indemnification obligation under the preceding sentence arises
as a result of any act or omission of a person who is an officer, shareholder or
other equity holder, director, employee, agent, attorney or consultant of the
Group (other than in connection with the activities of the Joint Planning
Board), such person shall not be entitled to indemnification in connection
therewith and any other adjustment as is equitable shall be made to
Administrator's or Parent's indemnification obligation arising thereby.


                                    ARTICLE X

                              Term and Termination

         Section 10.1 Term of Agreement. This Agreement shall commence on the
date hereof and shall expire on the 40th anniversary hereof unless earlier
terminated pursuant to the terms of either Section 10.3 or Section 10.4 or
automatically extended pursuant to the terms of Section 10.2.

         Section 10.2 Extended Term. Unless earlier terminated as provided for
in either Section 10.3 or Section 10.4, the term of this Agreement shall be
automatically extended for additional terms of five (5) years each, unless
either party delivers to the other party, not less than twelve (12) months nor
earlier than fifteen (15) months prior to the expiration of the preceding term,
written notice of such party's intention not to extend the term of this
Agreement.

         Section 10.3 Termination by the Group. The Group may, in its sole
discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not

                                       39
<PAGE>   45

the obligation, to cure any Material Adminstrator Default. Notwithstanding
anything to the contrary in this Agreement, following receipt by Administrator
of the notice of a Material Administrator Default and until such Material
Administrator Default shall be cured, the Group may take such action as may be
reasonably required to cover such Material Administrator Default so as to
maintain for the Group the same level of service as before the Material
Administrator Default, without prejudicing in any way the Group's other rights
and remedies, and may offset all of its costs from the amounts which may
otherwise be due to Administrator under this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that

                                       40

individual from participating in or from receiving reimbursement under any
program funded by the federal government or by any state government,
notwithstanding any available post-sanction remedies, or (4) is otherwise
disciplined by any licensing, regulatory or professional entity or institution,
the result of any of which event does or is reasonably expected to materially
adversely affect the Practice, the result of any of which event described in
subparagraphs (1) through (4) above, in the absence of termination of a
Physician Employee or a Physician Extender Employee or other action of the Group
to monitor and cure such act or conduct by such employee, does or reasonably
would be expected to materially and adversely affect the Practice or the Group.
Notwithstanding anything to the contrary in this Agreement, following receipt by
the Group of the notice of a Material Group Default, and until such Material
Group Default shall be cured, the Administrator may take such action as may be
reasonably required to cover such Material Group Default so as to maintain for
the Administrator the same level of service at the Premises as before the
Material Group Default, without prejudicing in any way Administrator other
rights and remedies, and may offset all of its costs of cover from amounts which
may otherwise due to the Group under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Stockholders and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
(with the exception of Hector Correa, Nancy Sussman, M.D., or Herbert Z. Geller)
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee [or Physician Extender Employee] that intends to
retire prior to expiration of such five-year period, then such Physician
Employee or Physician Extender Employee shall not be counted for purposes of
determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         (b) Upon the expiration of this Agreement pursuant to Sections 10.1 or
10.2.

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator and/or Parent, the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or their
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's or their Affiliates' accounting and financial records (the "Purchase
Assets"), including, but not limited to, without duplication, (i) all equipment,
furniture, fixtures, furnishings, inventory, supplies, improvements, additions
and leasehold improvements utilized by the Practice, (ii) any real estate owned
by Administrator, Parent or Affiliates that is occupied by or used primarily for
the benefit of the Practice, (iii) all unamortized intangible assets (including,
without limitation, goodwill) set forth on the financial statements of
Administrator, Parent or their Affiliates used solely in connection with the
Practice or otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and their Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c) Purchase Price. The Purchase Price shall be the lesser of (i) Fair
Market Value of the Purchase Assets subject to the assumption of the Practice
Related Liabilities or (ii) the value of the Actual Consideration (defined
below)(alternatively, the "Purchase Price"); provided, however, the Purchase
Price shall not be less than the net book value of the Purchase Assets at the
Termination Date. The Purchase Price shall be paid pursuant to Section 10.7. For
purposes of this subparagraph (c), the term "Actual Consideration" shall mean
(i) cash consideration paid to the Group pursuant to the Acquisition Agreement
and (2) an amount equal to the number of shares of Parent Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, reorganizations,
or any similar transaction whereby the Parent Common Stock is increased or
decreased or exchanged for a different number or kind of securities) issued
pursuant to the Acquisition Agreement multiplied by the fair market value of
Parent Common Stock immediately prior to the time that a Termination Notice is
provided pursuant to Section 10.7. The Purchase Price shall be appropriately
adjusted to offset and account for any monetary obligations of the Group or
Administrator owing to the other as provided herein.

         (d)      Exercise of Option.

                  (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                  (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

         (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at the Purchase Closing, Administrator and/or its Affiliates, as the case
may be, shall transfer and assign the Purchase Assets to the Group, and in
consideration therefor, the Group shall (a) pay to Administrator, Parent and/or
their Affiliates an amount in cash or, at the option of the Group (subject to
the conditions set forth below), Parent Common Stock (valued pursuant to Section
10.6(c) hereof), or some combination of cash and Parent Common Stock equal to
the Purchase Price and (b) assume the Practice Related Liabilities. The
structure of the transaction set forth in this Section 10.7 shall, if possible,
be structured as a tax-free transaction under applicable law. Each party shall
execute such documents or instruments as are reasonably necessary, in the
opinion of each party and its counsel, to effect the foregoing transaction. The
Group shall, and shall use its best efforts to cause each shareholder of the
Group to, execute such documents or instruments as may be necessary to cause the
Group to assume the Practice Related Liabilities and to release Administrator,
Parent and/or their Affiliates, as the case may be, from any liability or
obligation with respect thereto. In the event the Group desires to pay all or a
portion of the Purchase Price in shares of Parent Common Stock, such transaction
shall be subject to the satisfaction of each of the following conditions:


                                       43
<PAGE>   49

         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims, proxies, options, stockholders' agreements
and encumbrances (not including any applicable securities restrictions and
lock-up arrangements with the Parent or any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain financing for such acquisition but is unable to
obtain such financing and (iii) there is either a Material Administrator Default
pursuant to Section 10.3(a) or (c) or a Material Group Default pursuant to
Section 10.4(b) triggering a sale of the Purchase Assets, the Group shall be
entitled to obtain financing from Administrator, Parent and/or their Affiliates
but only for the difference between the Fair Market Value of the Purchase Assets
and the net book value of the Purchase Assets. The terms of such financing shall
be for a five (5) year period at an interest rate equal to the prime rate (as
published in the Wall Street Journal) plus four percent (4%) or such lesser rate
as is required to be in conformance with all applicable state and federal law.
In the event the Group is entitled to obtain financing from Administrator,
Parent and/or their Affiliates, the Group shall execute and deliver to
Administrator, Parent and/or their Affiliates all such documentation necessary
and appropriate to effectuate the financing transaction including, without
limitation, a secured promissory note, security agreement and financing
statements and such documentation shall contain such representations, warranties
and conditions customary to a secured transaction of this size.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator, Parent and/or their Affiliates to the
Group or the Group to the Administrator, Parent and/or their Affiliates


                                       44
<PAGE>   50

(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

         (a) Administrator, Parent and/or their Affiliates shall use their best
efforts to cooperate with the Group for the appropriate transfer of management
services.

         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.

         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.


                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

         Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means


                                       45
<PAGE>   51

set forth in Section 11.1 and prior to commencing an arbitration procedure
pursuant to this Article XI, the parties shall meet to discuss and consider
other alternative dispute resolution procedures other than arbitration,
provided, however that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including rules of
evidence and procedure. If at any time prior to the rendering of the decision by
the arbitrator (or pursuant to such other alternative dispute resolution
procedure) as contemplated in this Article XI to the extent a party makes a
written offer to the other party proposing a settlement of the matter(s) at
issue and such offer is rejected, then the party rejecting such offer shall be
obligated to pay the costs and expenses (excluding the amount of the award
granted under the decision) of the party that offered the settlement from the
date such offer was received by such other party if the decision is for a dollar
amount that is less than the amount of such offer to settle. Notwithstanding the
foregoing, the terms and provisions of this Article XI shall not preclude any
party hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

         Section 11.3 Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among Administrator and the Group arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within 30 days of notice
by a party to the other of its desire to seek arbitration under this Article XI
one arbitrator mutually acceptable to Administrator and the Group to hear and
decide all such claims under this Article XI. If such matter or action involves
health-care issues, then the arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators proposed shall be impartial
and independent of all parties. If the parties cannot agree on the selection of
an arbitrator within said 30-day period, then any party may in writing request
the judge of the United States District Court for the Southern District of New
York (White Plains) senior in term of service to appoint the arbitrator and,
subject to this Article XI, such arbitrator shall hear all arbitration matters
arising under this Article XI.

         Section 11.4 Applicable Rules.

         (a) Each arbitration hearing shall be held at a place in Weschester or
Rockland Counties, New York, acceptable to the arbitrator. The arbitration shall
be conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof. The decision of the arbitrator shall be reduced to writing and shall be
binding on the parties and such decision shall contain a concise statement of
the reasons in support of such decision. Judgment upon the award(s) rendered by
the arbitrator may be entered and execution had in any court of competent
jurisdiction or application may be made to such court for a judicial acceptance
of the award and an order of enforcement. The charges and expenses of the
arbitrator shall be shared equally by the parties to the hearing.

                                       46
<PAGE>   52

         (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI. In
fulfilling his duties with respect to determining the amount of any loss, the
arbitrator may consider such matters as, in the opinion of the arbitrator, are
necessary or helpful to make a proper valuation. The arbitrator may consult with
and engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

         (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.

         (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e) All privileges under New York and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying New York law.


                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment.

         (a) Administrator shall have the right to assign its rights hereunder
to Parent or any direct or indirect wholly-owned subsidiary of Administrator or
Parent (that remains a wholly-owned subsidiary of Administrator or Parent) or to
a financial institution as collateral security for the indebtedness of Parent,
Administrator or their Affiliates without the consent of the Group. No
assignment under subsection (a) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         (b) Administrator, Parent and their Affiliates shall provide notice to
the Group of Administrator's intent (i) to assign this Agreement (other than as
permitted in Section 12.1(a) herein), (ii) sell all or substantially all of the
assets of Administrator or (iii) effectuate a consolidation, merger or sale of a
majority of the capital stock of Administrator as soon as practicable following
a decision by the Parent's and Administrator's respective boards of directors to
seek such assignment or sale. The assignment of this Agreement (other than as
permitted in Section 12.1(a)), the sale of all or substantially all of the
assets of Administrator by Parent or a consolidation, merger or sale of a
majority of the capital stock of Administrator

                                       47
<PAGE>   53

shall not be permitted unless Administrator shall give written notice to the
Group stating the party who made the offer and specifying the purchase price
offered (the "Notice"). The Group shall have the option to repurchase the
Purchase Assets on the same terms and conditions set forth in the Notice. In the
event the Group fails to provide written notice to Administrator of its intent
to exercise its option to repurchase the Purchase Assets pursuant to this
Section 12.1 within the earlier of (i) thirty (30) days or (ii) one-half of the
time during which Administrator, Parent or their Affiliates must respond to an
offer following the Group's receipt of the Notice, the option contained in this
Section 12.1 shall be deemed null and void and of no further force and effect,
and Administrator shall be free to assign the Agreement, sell all or
substantially all of the assets of Administrator or sell or transfer all of the
capital stock Administrator without the consent of the Group. No assignment
under this subsection (b) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

         Section 12.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 12.4 Additional Documents. Each of the parties hereto agrees to
execute any document or documents that may be reasonably requested from time to
time by the other party to implement or complete such party's obligations
pursuant to this Agreement.

         Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,
costs and expenses including, but not limited to, attorney's fees, costs and
expenses for trial, appellate proceedings and negotiations, in addition to any
other relief granted.

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group
and Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this
Agreement should be construed or deemed, by any governmental authority, agency
or court to constitute the practice of medicine, the performance of said act or
service by Administrator shall be deemed waived and forever unenforceable and
the provisions of this Section 12.6 shall be applicable. Neither party shall
claim or assert illegality as a defense to the enforcement of this Agreement or
any provision

                                       48
<PAGE>   54

hereof; instead, any such purported illegality shall be resolved pursuant to the
terms of this Section 12.6 and Section 12.9.

         Section 12.7 Parties In Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto. Except
as provided in Section 6.1(g), neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party hereto
or thereto any rights or remedies hereunder or thereunder.

         Section 12.8 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

         Section 12.9 Severability. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 12.10 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULE GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

         Section 12.11 No Waiver; Remedies Cumulative. No party hereto shall by
any act (except by written instrument pursuant to Section 12.3 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default in or breach of any of the terms
and conditions hereof. No failure to exercise, nor any delay in exercising, on
the part of any party hereto, any right, power or privilege hereunder shall
operate as a waiver thereof. No single or partial exercise of any right, power
or privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. No remedy set forth in this

         Section 3.1 General.

         (a) Scope of Services Provided. Administrator shall provide or arrange
for the services set forth in this Article III, and the costs, fees, expenses
and other disbursements incurred by Administrator or Parent in connection
therewith shall be included in Practice Expenses, except to the extent such
costs, fees or expenses are expressly included in Excluded Practice Expenses or
Administrator Expenses. Administrator is authorized to perform its services
hereunder as is necessary or appropriate for the efficient operation of the
Practice, including, without limitation, performance of some of the business
office functions at locations other than the Practice. Except to the extent
necessary to comply with applicable laws, regulations or professional ethical

assistance to Administrator as is reasonably required by Administrator to
perform its services hereunder. Administrator shall cause its employees, to
comply with all applicable federal, state and local laws, rules and regulations
in Administrator's provision of services hereunder.

         (b) Alternative Management Arrangements.

procedures Administrator, Parent or their Affiliates shall utilize to restore
the level of service contemplated by this Agreement. In the event Administrator
fails to restore the level of service contemplated by this Agreement in
accordance with such plan submitted or in any event within ninety (90) days, the
Group shall be entitled to reimbursement by Administrator for the reasonable
costs and expenses of obtaining such service on a temporary basis until such
time Administrator demonstrates its ability to perform such service at the level
contemplated by this Agreement. Nothing contained in this subsection (b)(i)
shall be construed to limit the Group's ability to provide notice of a Material
Administrator Default pursuant to Section 10.3(b) of this Agreement.

                  (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service
is construed or deemed to constitute the practice of medicine, Administrator
shall deliver to the Group notice of such an event. The Group shall be entitled
to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

its exclusive manager and administrator of non-medical business services

Administrator shall have all necessary authority and hereby agrees to perform
such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

         (b) Billing and Collection.

                  (i) Administrator shall, in the name of and on behalf of the

the Practice at the Premises or any Practice Site(s) (including all fees
generated by both the Technical Operations and the Professional Operations), for
services performed outside the Practice for its hospitalized patients, and for
all other professional and Practice services. The Group hereby appoints
Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:


                                       10
<PAGE>   16
                           (A) to bill patients, insurance companies, Managed
Care Payors, and other third-party payors in the Group's name and on its behalf;

                           (B) to collect accounts receivable resulting from
such billing not otherwise purchased by Administrator (as provided for in
Section 3.2(e) hereof) in the Group's name and on its behalf;

                           (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                           (D) to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                           (E) to take possession of and endorse in the name of
the Group and deposit into the Deposit Account (and/or in the name of an
individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                           (F) upon the prior consent of the Group, which
consent shall not be unreasonably withheld or delayed, to initiate the
institution of legal proceedings in the name of the Group or a Physician
Employee to collect any accounts and monies owed to the Group or the Physician
Employee, to enforce the rights of the Group or the Physician Employee, as the
case may be, as creditor under any contract or in connection with the rendering
of any service, and to contest adjustments and denials by governmental agencies
(or their fiscal intermediaries) as third-party payors.

                  (ii) The Group hereby appoints Administrator as its true and
lawful attorney-in-fact to deposit into the Deposit Account all Professional
Revenues and Technical Revenues collected by Administrator as provided for in
this Section 3.2(b). The Group covenants, and shall cause all Physician
Employees and Physician Extender Employees to covenant, to forward any payments
received with respect to any Professional Revenues or Technical Revenues
generated for services provided by the Group or any of its Physician Employees
and Physician Extender Employees to Administrator for deposit. Administrator
shall have the right to withdraw funds from the Deposit Account and all owners
of the Deposit Account shall execute a revocable standing transfer order (the
"Transfer Order") under which the bank maintaining the Deposit Account shall
periodically transfer the entire balance of the Deposit Account to a separate
bank account owned solely by Administrator (the "Administrator Account"). The
Group and Administrator hereby agree to execute from time to time such documents
and instructions as shall be required by the bank maintaining the Deposit
Account and mutually agreed upon to effectuate the foregoing provisions and to
extend or amend such documents and instructions. Any action by the Group that
materially interferes with the operation of this Section, including but not
limited to, any failure to deposit or to have Administrator deposit any


                                       11
<PAGE>   17
Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit Account not authorized by the express
terms of this Agreement or any other written agreement executed by each of the
parties, or any revocation of or attempt to revoke the Transfer Order (otherwise
than upon expiration or termination of this Agreement), will constitute a breach
of this Agreement and will entitle Administrator, in addition to any other
remedies it may have at law or in equity, to seek a court ordered assignment of
the rights provided to Administrator pursuant to subparagraph (i) above.

                  (iii) All monies shall be accounted for by Administrator as
being distinctly attributable to the Group. The Group may perform the functions
or exercise the rights set forth in this Section 3.2(b) only with the prior
written consent of Administrator. The Group shall execute such documents in form
and substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c) Accounting. Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of
the Practice, and Administrator shall perform all bookkeeping and accounting
services necessary or appropriate for the efficient operation of the Practice,
including the maintenance, custody and supervision of business records, ledgers
and reports; the establishment, administration and implementation of accounting
procedures, controls and systems; and implementation and management of
computer-based management information systems. The Group and its authorized
representatives shall have the right to review all financial books and records
maintained by Administrator relating to the operation of the Practice and to the
cash management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the parties have
agreed herein. The purchase price shall be an amount equal to the aggregate face
amount of the accounts receivable being sold less contractual adjustments and


                                       12
<PAGE>   18
estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

         (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication
services and medical transcribing services; provided, however, that the Group
may elect to prepare its own Tax Returns, in which case, the cost of preparing
such Tax Returns in excess of $2,500 per annum shall be included in Excluded
Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group
containing a balance sheet, income statement and monthly operational reports
which detail payments, charges and accounts receivable statistics, monthly
reconciliation reports on cash management and any other financial reports
reasonably requested by a member of the Joint Planning Board designated by the
Group, which shall be delivered to the Group as soon as practicable, but no
later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

         (g) Records and Files.

                  (i) Administrator's Business and Financial Records. At all
times during and after the term of this Agreement, including any extensions or
renewals hereof, all business records, including but not limited to, business
agreements, books of account, personnel records, general administrative records
and all information generated under or contained in the management information
system pertaining to Administrator's obligations hereunder, and other business
information of Administrator of any kind or nature, except for patient medical
records and the Group's Records (as defined in subparagraph (ii) below), shall
be and remain the sole property of Administrator; provided that during and after
termination of this Agreement, the Group shall be entitled to reasonable access
to such records and information, including the right to obtain copies thereof in
any media reasonably requested by the Group, for any purpose related to patient
care or the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years. Administrator hereby agrees
to preserve the confidentiality of such patient medical records and to use the
information in such records only for the limited purposes necessary to perform
management services and, within the limits of its responsibilities hereunder, to
ensure that provision is made for appropriate care for patients of the Practice.

<PAGE>   19
                  (ii) The Practice's Business and Financial Records. At all
times during and after the term of this Agreement, the business agreements,
financial, operational, corporate and personnel records and information relating
exclusively to the business and activities of the Group and patient medical
records and charts (hereinafter referred to as the "Group's Records") shall be
and remain the sole property of the Group.

                  (iii) Access to Records. At all times during and after the
term of this Agreement, each party and its authorized agents shall be entitled,
upon request and with reasonable advance notice, to obtain access (within not
more than 30 days following receipt of such notice by the other party or
parties) to all records of the other party directly related to the performance
of such party's obligations pursuant to this Agreement; provided, however, that
such right shall not allow for access to patient, medical and other records that
must be kept confidential as required by law. Either party, at its expense,
shall have the right to make copies in any media of any records to which it has
access pursuant to this subparagraph (iii).

                  (iv) Compliance with Law. The management of all files and
records by Administrator and the Group shall comply with all applicable federal,
state and local statutes and regulations.

         (h) Collections. Subject to the consent requirement contained in
Section 3.2(b)(i)(F), Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees and
pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

         Section 3.3 Facilities.

Premises that are described in Exhibit 3.3(a) attached hereto and such other
improvements made by Administrator or Parent for the use of the Group hereunder.

property necessary or appropriate for the efficient operation of the Practice
acquired by Administrator or Parent (subject to review and approval of the Joint

(collectively, the "Personal Property"). Administrator shall maintain the
Personal Property in good condition and make or cause to be made all necessary
repairs thereto.


                                       14
<PAGE>   20
         (c) Expenses. All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the
Premises and the Personal Property, including, without limitation, all
reasonably necessary costs of repairs, maintenance and improvements, utility
expenses (i.e., telephone, electric, gas and water), janitorial services, refuse
disposal, real or personal property lease cost payments and expenses, interest,
refinancing expenses, depreciation, loss on disposition of assets, taxes and
casualty, liability and other insurance, shall be included in Practice Expenses.
To the extent the Premises or Personal Property are used in connection with the
Professional Operations, the costs and expenses associated with such usage shall
be allocated between Professional Expenses and Technical Expenses as approved by
the Joint Planning Board.

         (d) Disposition. Subject to provisions contained in existing agreements
to which Administrator or Parent is or becomes a party and, where necessary and
appropriate for the efficient operation of the Practice, nothing herein shall be
construed as precluding Administrator or Parent from selling, leasing or
otherwise disposing of all or any part of the Premises, Personal Property, real
property, improvements, trade names, trademarks and other intangible property;
provided, however, any such sale, lease or disposition shall be subject to the
prior review and approval of the Joint Planning Board and shall not eliminate or
diminish Administrator's obligations hereunder.

         (e) No Warranties or Representations. The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

         Section 3.4 Acquisition and Assistance.

         (a) Employment of Physicians. Subject to consultation with the Joint
Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice. Subject to
consultation with the Joint Planning Board, in the event that a decision is made
by the Group to pursue the employment of selected physicians, if requested by
the Group, Administrator will provide recruiting, consulting, negotiating and
other advisory services in connection with such transaction. Notwithstanding the
preceding, as set forth in and subject to the provisions of Section 4.1 hereof,
the Group shall have complete control of and responsibility for the hiring of
all Physician Employees and Physician Extender Employees.

         (b) Acquisitions. In the event that the Group contemplates acquiring or
affiliating with a physician group, practice or other entity, and such
acquisition or affiliation involves the use or expenditure of Administrator's
and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a
result of such an acquisition or affiliation including, without limitation,
capital and personnel (collectively, the "Resources"), then the Group shall
first consult with the Joint Planning Board and Administrator, and any decision
to make such affiliation or acquisition shall


                                       15
<PAGE>   21
be subject to prior approval of Administrator, which decision of the
Administrator shall be provided to the Group in a reasonable and timely manner
following satisfactory review of the physician group, practice or other entity
to be acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto. If such contemplated acquisition or affiliation does not
involve the use or expenditure of any of Administrator's and/or Parent's
Resources, then such decision shall be in the sole discretion of the Group.
Notwithstanding any provision contained herein to the contrary, any person or
entity with which the Group affiliates or acquires shall be subject to the terms
and conditions of this Agreement. If a decision is made to proceed with any
affiliation or acquisition of a physician group or practice, the Group may seek
from Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

         Section 3.5 Financial Planning and Budgeting.

         (a) Budgeting. Administrator shall collaborate with the Group and the
Joint Planning Board in the preparation of all annual capital and operating
budgets. These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors. For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board. The
projected annual operating budget for each subsequent year shall be subject to
the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice. For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

         (b) Capital Expenditures. Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

                  (i) Budgeted Expenditures. All budgeted capital expenditures
and improvement projects shall be subject to final review and approval by the
Joint Planning Board prior to the making of any actual expenditure. Such review
and approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.


                                       16
<PAGE>   22
                  (ii) Non-Budgeted Expenditures. Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared by
the Joint Planning Board in consultation with the Group and Administrator. All
requests for non-budgeted capital expenditures and improvements at or for the
benefit of the Practice in excess of either $75,000 individually or an aggregate
amount equivalent to $2,500 multiplied by the number of Full-time Physician
Employees employed at the time the capital budget for such Group for the
applicable year is determined (provided, however, that such aggregate amount
shall not exceed $250,000 for any calendar year) must be approved by the Board
of Directors of Parent or by any committee specifically designated by the Board
of Directors of Parent for such purposes.

         (c) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors"). Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning


                                       17
<PAGE>   23
Board, be the responsibility of the Group. Notwithstanding the preceding
language, if a contract or relationship between any Managed Care Payor and the
Group involves or affects a contract or relationship with any other physician
group or practice serviced or managed by Administrator, Parent or any of their
Affiliates (the "Other Practices") and a consensus among the Group and the Other
Practices cannot be reached regarding the contract or relationship, then the
ultimate decision as to the approval, disapproval, termination or amendment of
such contract or relationship involving the Group, the Other Practices and such
Managed Care Payor shall be determined by the affirmative vote of the Physician
Board Members (as defined below) who hold a majority of the Group Voting Power
(as defined below). For purposes of this Section 3.7, (i) the term "Physician
Board Members" shall mean (a) those members appointed by the Group who serve on
the Joint Planning Board and (b) those persons appointed by the Other Practices
who serve on the Other Practices' joint boards (in a similar capacity to the
Joint Planning Board) as part of their contractual relationship with Parent,
Administrator or any of their Affiliates, and (ii) the term "Group Voting Power"
shall mean the total voting percentage which may be cast by the Physician Board
Members on a collective basis, with the percentage of votes able to be cast by
any Group or Other Practice, as applicable, shall be equal to the quotient
determined by dividing (x) the total estimated annual professional revenues to
be generated by the Group from such Managed Care Contract as determined by
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion, by (y) the total estimated annual professional revenues to be
generated by the Group and all Other Practices from such Managed Care Contract
as determined by the Administrator, Parent or their Affiliates, as appropriate,
in its sole discretion.

         Section 3.8 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.9 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and advertising programs shall be
conducted in compliance with applicable standards of medical ethics, laws and
regulations.


                                       18
<PAGE>   24
         Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program
shall be included in Administrator Expenses; provided, however, that any
expenses related to such program that are incurred for services provided solely
for the direct benefit of the Practice shall be included in Practice Expenses.

         Section 3.11 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by
the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

         Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.


                                   ARTICLE IV

                            Obligations of the Group

         Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender
Employees, and other employees who may have malpractice exposure or liability,
are insurable and by participating in an ongoing risk management program.


                                       19
<PAGE>   25
         Section 4.2 Professional Services. The Group shall provide professional
services to its patients in compliance at all times with ethical standards,
laws, rules and regulations applicable to the operations of the Practice, the
Physician Employees and Physician Extender Employees. The Group shall ensure
that each Physician Employee and each Physician Extender Employee has all
required licenses, credentials, approvals or other certifications to perform his
or her duties and services for the Practice and, in the event that the Group
becomes aware of any disciplinary actions or medical malpractice actions
initiated against any Physician Employee or Physician Extender Employee, the
Group shall promptly inform Administrator of such action and the underlying
facts and circumstances. If required by applicable law, any state or federal
regulatory agency or any contractual obligations, the Group shall carry out a
program to monitor the quality of medical care practiced at the Practice;
provided, however, that the preceding language shall not limit the Group's
obligation to participate in or comply with any programs established by
Administrator or Parent for purposes of ensuring that the Group complies with
applicable law. The Group shall employ Physician Employees and Physician
Extender Employees as is necessary to provide efficient medical care to patients
of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery
items on prepaid Managed Care Contracts which are authorized and permitted by

         Section 5.1 Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy is counted;
provided, however, that no proxy shall be valid after the expiration of eleven
(11) months from the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2 Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

the particular project and the Group as a whole.

         (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess
of five percent (5%) to the annual capital or operating budgets.

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

adopt the fee schedule for all ancillary services.

         (f) Provider and Payor Relationships. Subject to Section 3.7, decisions
regarding the establishment or maintenance of relationships with institutional
health care providers and payors shall be approved by the Group after
consultation with the Joint Planning Board.

         (g) Strategic Planning. The Joint Planning Board shall develop a plan

priority of capital expenditures in accordance with Section 3.5(b) hereof.

Board. The Group agrees that, unless the following are approved in advance by
the Joint Planning Board and such act of the Joint Planning Board includes the

Joint Planning Board. No action of the Joint Planning Board shall be effective
unless authorized by the members holding a majority of the voting power of the
Joint Planning Board present or represented by proxy at the applicable meeting.

a tie vote, and no compromise can be reached, then either (x) the Board of
Directors of Parent or (y) a committee designated by the Board of Directors of
Parent containing at least one (1) physician member will make a final
determination on the matter in dispute provided that both the Group and
Administrator shall have had an opportunity to make a presentation to the Board
of Directors of Parent or a committee thereof, as applicable. A quorum of the
Joint Planning Board shall consist of the members holding a majority of the
voting power of the Joint Planning Board, present in person, by telephone, or by
proxy and the quorum must remain for the duration of the meeting.

Notice must be given or sent to the member's address or telephone number as

business who would reasonably be expected to communicate that notice promptly to
the member.

                  (i) Written Waiver, Consent or Approval. Notice of a special
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the special meeting. Such waiver,
consent or approval need not specify the purpose of the special meeting. All
such waivers, consents, and approvals shall be filed with the Joint Planning
Board records or made a part of the minutes of the special meetings.

                  (ii) Failure to Object. Notice of special meeting need not be

and nondisclosure of confidential/proprietary information and engagement of
Administrator covenants similar to those applicable to the Group as contained in
Section 6.1 hereof. Except as otherwise approved by the Joint Planning Board,
each Group Physician Stockholder or Full-time Physician Employee shall agree
that during the term of his/her employment or contractor agreement with the
Group (w) not to practice radiological medicine other than at the Premises or
such other location or Practice Site(s) as approved by the Joint Planning Board;
(x) to devote substantially all of his or her professional time, effort and
ability to the Practice; (y) to request in writing and receive in writing prior
approval from the Joint Planning Board to engage in any outside medical
activities; and (z) to turn over to the Practice, to be included in Professional
Revenues attributed to the Practice, any income derived by such Group Physician
Stockholder or Full-time Physician Employee from any outside medical activity or
related source from the following medically-related activities: teaching,
consulting,


                                       30
<PAGE>   36
medical research, inventions developed utilizing the Group's or the Practice's
time and material, testimony for litigation, and insurance examinations. The
Group shall not materially amend, alter or otherwise change any term or
provision of any Stockholder Employment Agreement or Physician Employee
Employment Agreement relating to the foregoing covenants in this Section 6.2
without the prior written consent of Administrator; notwithstanding the
foregoing, any such amendment, alteration or change shall not be inconsistent
with the terms or provisions of this Agreement. Following termination of this
Agreement, the Group shall not amend, alter or otherwise change any term or
provision of the Restrictive Covenants, unless such provisions are no longer in
force and effect pursuant to the terms of the applicable Stockholder Employment
Agreement or Physician Employee Employment Agreement at the time of termination
of this Agreement. In the event the Purchase Assets are acquired by the Group
pursuant to Article X, the obligation of the Group to enforce Restrictive
Covenants shall be limited to enforcement of non-solicitation and nondisclosure
of confidential/proprietary information covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Stockholder Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Stockholder Employment
Agreements and, to the extent permitted under applicable law, the Physician
Employee Employment Agreements, upon the request of Administrator, the Group
shall assign to Administrator such causes of action and/or other rights it has
related to such breach or default and shall cooperate with and provide
reasonable assistance to Administrator with respect thereto; in which case, all
costs and expenses incurred in connection therewith shall be borne by
Administrator and shall be included in Administrator Expenses, and Administrator
shall be entitled to all damages and other amounts recovered thereby. In the
event the Purchase Assets are acquired by the Group pursuant to Article X, the
obligation of the Group to enforce Restrictive Covenants shall be limited to
enforcement of non-solicitation and nondisclosure of confidential/proprietary
information covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period,


                                       31
<PAGE>   37
scope of activity restricted and/or the geographical area applicable to such
provision of the Restrictive Covenants or this Article VI. The invalidity or
non-enforceability of any provision of the Restrictive Covenants or this Article
VI in any respect shall not affect the validity or enforceability of the
remainder of the Restrictive Covenants or this Article VI or of any other
provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Stockholder or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Stockholder or Full-time Physician Employee from the restrictive
covenants contained in Section 6.2, above. In the event the Group elects to
release such Group Physician Stockholder or Full-time Physician Employee, the
Group hereby covenants that it shall obtain a formal agreement between each
Group Physician Stockholder or Full-time Physician Employee, as the case may be,
and Administrator which provides that, for a period of two (2) years following
termination of any employment agreement with the Group, such Group Physician
Stockholder or Full-time Physician Employee agrees to (a) engage Administrator
as the sole and exclusive manager and administrator of the non-medical functions
and services of said Group Physician Stockholder's or Full-time Physician
Employee's medical practice and (b) pay to Administrator the identical amount
[NY only] of revenues paid by the Group to the Administrator attributable to
such Group Physician Stockholder or Full-time Physician Employee derived from
such Group Physician Stockholder's or Full-time Physician Employee's performance
of professional medical services within 15 miles of any Practice Site.

         Section 6.6 Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary
information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and


                                       32
<PAGE>   38
work effort required and (y) the Group shall not be required to employ any
Radiologist previously associated with such Professional Service Opportunity.

         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half of the time during which the
Administrator, Parent or their Affiliates must respond to an offer described in
the Administrator's Notice, the Group shall deliver to Administrator a written
notice stating whether or not the Group elects to accept or reject the New
Professional Service Opportunity which election shall be binding on the Group.
If the Group does not elect to exercise the right or fails to provide the notice
to Administrator within the time frame herein provided, Administrator shall be
released from the right of first offer with respect to that particular New
Professional Service Opportunity. Prior to consummating any asset acquisition,
merger or other consolidation of any Radiologist, group of Radiologists, or
professional corporation or association (or other professional entity) whose
owners are Radiologists within any Secondary Service Area, Administrator shall
first consult with the Joint Planning Board.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service Opportunity as contemplated in
subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

            "New Professional Service Opportunity" shall mean a Professional
Service Opportunity pursuant to which the Group or any other member of an APPI
Group managed by Parent, Administrator or their Affiliates is not currently
providing professional Radiology services.

            "Primary Service Area" shall mean that area within a five (5) mile
radius from any imaging center owned, operated or managed by Administrator,
Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.


                                       33
<PAGE>   39
            "Professional Service Opportunity" shall mean any opportunity to

            "Radiology" shall mean and include diagnostic imaging,
interventional radiology and radiation oncology services.

            "Secondary Service Area" shall mean (i) during the 12-month period
following the Acquisition Effective Date, that area which extends ten (10) miles
beyond the boundary of any Primary Service Area and (ii) during the remaining
term of this Agreement, that area which extends five (5) miles beyond the
boundary of any Primary Service Area.

         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.


                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on


                                       34
<PAGE>   40
Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates based
upon available information for such month, and adjustments to the estimated
payments shall be made to reconcile final amounts due under Section 7.1 on the
next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee


                                       35
<PAGE>   41
and to other related provisions of this Agreement shall be a joint decision of
the parties, shall be memorialized in a written amendment to this Agreement, and
shall be based upon the methodology used to generally determine Services Fees
hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

         (a)      payment of all accrued Practice Expenses for the prior month
                  (subject to the proviso in the preceding sentence;

         (b)      payment of the accrued Service Fee for the prior month;

         (c)      payment of outstanding balance of all amounts advanced to the
                  Group, through the end of the prior month, and applicable
                  interest thereon (as contemplated in Section 7.3); and

         (d)      payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).


                                  ARTICLE VIII

                                     Records

         Section 8.1 Records. All records relating in any way to the operation
of the Practice (other than Group Records) shall, subject to the obligations of
the Practice to maintain patient medical records pursuant to Section 3.2(g), at
all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter, the
Group or its agents shall have reasonable access during normal business hours to
the Group's and Administrator's personnel and financial records relating to the
Practice, including, but not limited to, records of collections, expenses and
disbursements as kept by Administrator in


                                       36
<PAGE>   42
performing Administrator's obligations under this Agreement, and the Group may
copy any or all such records.


                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1 Insurance to be Maintained by the Group.

         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.


                                       37
<PAGE>   43
         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.

         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5 Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its shareholders, employees
and/or subcontractors (other than Administrator, Parent, Affiliates or their
employees, officers, directors, agents, attorneys and consultants) during the
term of this Agreement. Provided, however, that in the event an indemnification
obligation under the preceding sentence arises as of the result of any act or
omission of a person who is an officer, shareholder or other equity holder,
director, employee, agent, attorney or consultant of Administrator, Parent or
any of their Affiliates (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
the Group's indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or
incurred, that are caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts or omissions by Administrator, Parent or Affiliates and/or any of
their respective shareholders, employees and/or subcontractors (other than the
Group or its employees) during the term of this Agreement. Provided, however
that


                                       38
<PAGE>   44
in the event an indemnification obligation under the preceding sentence arises
as a result of any act or omission of a person who is an officer, shareholder or
other equity holder, director, employee, agent, attorney or consultant of the
Group (other than in connection with the activities of the Joint Planning
Board), such person shall not be entitled to indemnification in connection
therewith and any other adjustment as is equitable shall be made to
Administrator's or Parent's indemnification obligation arising thereby.


                                    ARTICLE X

                              Term and Termination

         Section 10.1 Term of Agreement. This Agreement shall commence on the
date hereof and shall expire on the 40th anniversary hereof unless earlier
terminated pursuant to the terms of either Section 10.3 or Section 10.4 or
automatically extended pursuant to the terms of Section 10.2.

         Section 10.2 Extended Term. Unless earlier terminated as provided for
in either Section 10.3 or Section 10.4, the term of this Agreement shall be
automatically extended for additional terms of five (5) years each, unless
either party delivers to the other party, not less than twelve (12) months nor
earlier than fifteen (15) months prior to the expiration of the preceding term,
written notice of such party's intention not to extend the term of this
Agreement.

         Section 10.3 Termination by the Group. The Group may, in its sole
discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not


                                       39
<PAGE>   45
the obligation, to cure any Material Adminstrator Default. Notwithstanding
anything to the contrary in this Agreement, following receipt by Administrator
of the notice of a Material Administrator Default and until such Material
Administrator Default shall be cured, the Group may take such action as may be
reasonably required to cover such Material Administrator Default so as to
maintain for the Group the same level of service as before the Material
Administrator Default, without prejudicing in any way the Group's other rights
and remedies, and may offset all of its costs from the amounts which may
otherwise be due to Administrator under this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that


                                       40

individual from participating in or from receiving reimbursement under any
program funded by the federal government or by any state government,
notwithstanding any available post-sanction remedies, or (4) is otherwise
disciplined by any licensing, regulatory or professional entity or institution,
the result of any of which event does or is reasonably expected to materially
adversely affect the Practice, the result of any of which event described in
subparagraphs (1) through (4) above, in the absence of termination of a
Physician Employee or a Physician Extender Employee or other action of the Group
to monitor and cure such act or conduct by such employee, does or reasonably
would be expected to materially and adversely affect the Practice or the Group.
Notwithstanding anything to the contrary in this Agreement, following receipt by
the Group of the notice of a Material Group Default, and until such Material
Group Default shall be cured, the Administrator may take such action as may be
reasonably required to cover such Material Group Default so as to maintain for
the Administrator the same level of service at the Premises as before the
Material Group Default, without prejudicing in any way Administrator other
rights and remedies, and may offset all of its costs of cover from amounts which
may otherwise due to the Group under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Stockholders and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
(with the exception of Hector Correa, Nancy Sussman, M.D., or Herbert Z. Geller)
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee [or Physician Extender Employee] that intends to
retire prior to expiration of such five-year period, then such Physician
Employee or Physician Extender Employee shall not be counted for purposes of
determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         (b) Upon the expiration of this Agreement pursuant to Sections 10.1 or
10.2.

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator and/or Parent, the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or their
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's or their Affiliates' accounting and financial records (the "Purchase
Assets"), including, but not limited to, without duplication, (i) all equipment,
furniture, fixtures, furnishings, inventory, supplies, improvements, additions
and leasehold improvements utilized by the Practice, (ii) any real estate owned
by Administrator, Parent or Affiliates that is occupied by or used primarily for
the benefit of the Practice, (iii) all unamortized intangible assets (including,
without limitation, goodwill) set forth on the financial statements of
Administrator, Parent or their Affiliates used solely in connection with the
Practice or otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and their Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c) Purchase Price. The Purchase Price shall be the lesser of (i) Fair
Market Value of the Purchase Assets subject to the assumption of the Practice
Related Liabilities or (ii) the value of the Actual Consideration (defined
below)(alternatively, the "Purchase Price"); provided, however, the Purchase
Price shall not be less than the net book value of the Purchase Assets at the
Termination Date. The Purchase Price shall be paid pursuant to Section 10.7. For
purposes of this subparagraph (c), the term "Actual Consideration" shall mean
(i) cash consideration paid to the Group pursuant to the Acquisition Agreement
and (2) an amount equal to the number of shares of Parent Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, reorganizations,
or any similar transaction whereby the Parent Common Stock is increased or
decreased or exchanged for a different number or kind of securities) issued
pursuant to the Acquisition Agreement multiplied by the fair market value of
Parent Common Stock immediately prior to the time that a Termination Notice is
provided pursuant to Section 10.7. The Purchase Price shall be appropriately
adjusted to offset and account for any monetary obligations of the Group or
Administrator owing to the other as provided herein.

         (d) Exercise of Option.

                  (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                  (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

         (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at the Purchase Closing, Administrator and/or its Affiliates, as the case
may be, shall transfer and assign the Purchase Assets to the Group, and in
consideration therefor, the Group shall (a) pay to Administrator, Parent and/or
their Affiliates an amount in cash or, at the option of the Group (subject to
the conditions set forth below), Parent Common Stock (valued pursuant to Section
10.6(c) hereof), or some combination of cash and Parent Common Stock equal to
the Purchase Price and (b) assume the Practice Related Liabilities. The
structure of the transaction set forth in this Section 10.7 shall, if possible,
be structured as a tax-free transaction under applicable law. Each party shall
execute such documents or instruments as are reasonably necessary, in the
opinion of each party and its counsel, to effect the foregoing transaction. The
Group shall, and shall use its best efforts to cause each shareholder of the
Group to, execute such documents or instruments as may be necessary to cause the
Group to assume the Practice Related Liabilities and to release Administrator,
Parent and/or their Affiliates, as the case may be, from any liability or
obligation with respect thereto. In the event the Group desires to pay all or a
portion of the Purchase Price in shares of Parent Common Stock, such transaction
shall be subject to the satisfaction of each of the following conditions:


                                       43
<PAGE>   49
         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims, proxies, options, stockholders' agreements
and encumbrances (not including any applicable securities restrictions and
lock-up arrangements with the Parent or any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain financing for such acquisition but is unable to
obtain such financing and (iii) there is either a Material Administrator Default
pursuant to Section 10.3(a) or (c) or a Material Group Default pursuant to
Section 10.4(b) triggering a sale of the Purchase Assets, the Group shall be
entitled to obtain financing from Administrator, Parent and/or their Affiliates
but only for the difference between the Fair Market Value of the Purchase Assets
and the net book value of the Purchase Assets. The terms of such financing shall
be for a five (5) year period at an interest rate equal to the prime rate (as
published in the Wall Street Journal) plus four percent (4%) or such lesser rate
as is required to be in conformance with all applicable state and federal law.
In the event the Group is entitled to obtain financing from Administrator,
Parent and/or their Affiliates, the Group shall execute and deliver to
Administrator, Parent and/or their Affiliates all such documentation necessary
and appropriate to effectuate the financing transaction including, without
limitation, a secured promissory note, security agreement and financing
statements and such documentation shall contain such representations, warranties
and conditions customary to a secured transaction of this size.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator, Parent and/or their Affiliates to the
Group or the Group to the Administrator, Parent and/or their Affiliates


                                       44
<PAGE>   50
(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

         (a) Administrator, Parent and/or their Affiliates shall use their best
efforts to cooperate with the Group for the appropriate transfer of management
services.

         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.

         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.


                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

         Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means


                                       45
<PAGE>   51
set forth in Section 11.1 and prior to commencing an arbitration procedure
pursuant to this Article XI, the parties shall meet to discuss and consider
other alternative dispute resolution procedures other than arbitration,
provided, however that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including rules of
evidence and procedure. If at any time prior to the rendering of the decision by
the arbitrator (or pursuant to such other alternative dispute resolution
procedure) as contemplated in this Article XI to the extent a party makes a
written offer to the other party proposing a settlement of the matter(s) at
issue and such offer is rejected, then the party rejecting such offer shall be
obligated to pay the costs and expenses (excluding the amount of the award
granted under the decision) of the party that offered the settlement from the
date such offer was received by such other party if the decision is for a dollar
amount that is less than the amount of such offer to settle. Notwithstanding the
foregoing, the terms and provisions of this Article XI shall not preclude any
party hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

         Section 11.3 Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among Administrator and the Group arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within 30 days of notice
by a party to the other of its desire to seek arbitration under this Article XI
one arbitrator mutually acceptable to Administrator and the Group to hear and
decide all such claims under this Article XI. If such matter or action involves
health-care issues, then the arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators proposed shall be impartial
and independent of all parties. If the parties cannot agree on the selection of
an arbitrator within said 30-day period, then any party may in writing request
the judge of the United States District Court for the Southern District of New
York (White Plains) senior in term of service to appoint the arbitrator and,
subject to this Article XI, such arbitrator shall hear all arbitration matters
arising under this Article XI.

         Section 11.4 Applicable Rules.

         (a) Each arbitration hearing shall be held at a place in Weschester or
Rockland Counties, New York, acceptable to the arbitrator. The arbitration shall
be conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof. The decision of the arbitrator shall be reduced to writing and shall be
binding on the parties and such decision shall contain a concise statement of
the reasons in support of such decision. Judgment upon the award(s) rendered by
the arbitrator may be entered and execution had in any court of competent
jurisdiction or application may be made to such court for a judicial acceptance
of the award and an order of enforcement. The charges and expenses of the
arbitrator shall be shared equally by the parties to the hearing.


                                       46
<PAGE>   52
         (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI. In
fulfilling his duties with respect to determining the amount of any loss, the
arbitrator may consider such matters as, in the opinion of the arbitrator, are
necessary or helpful to make a proper valuation. The arbitrator may consult with
and engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

         (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.

         (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e) All privileges under New York and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying New York law.


                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment.

         (a) Administrator shall have the right to assign its rights hereunder
to Parent or any direct or indirect wholly-owned subsidiary of Administrator or
Parent (that remains a wholly-owned subsidiary of Administrator or Parent) or to
a financial institution as collateral security for the indebtedness of Parent,
Administrator or their Affiliates without the consent of the Group. No
assignment under subsection (a) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         (b) Administrator, Parent and their Affiliates shall provide notice to
the Group of Administrator's intent (i) to assign this Agreement (other than as
permitted in Section 12.1(a) herein), (ii) sell all or substantially all of the
assets of Administrator or (iii) effectuate a consolidation, merger or sale of a
majority of the capital stock of Administrator as soon as practicable following
a decision by the Parent's and Administrator's respective boards of directors to
seek such assignment or sale. The assignment of this Agreement (other than as
permitted in Section 12.1(a)), the sale of all or substantially all of the
assets of Administrator by Parent or a consolidation, merger or sale of a
majority of the capital stock of Administrator


                                       47
<PAGE>   53
shall not be permitted unless Administrator shall give written notice to the
Group stating the party who made the offer and specifying the purchase price
offered (the "Notice"). The Group shall have the option to repurchase the
Purchase Assets on the same terms and conditions set forth in the Notice. In the
event the Group fails to provide written notice to Administrator of its intent
to exercise its option to repurchase the Purchase Assets pursuant to this
Section 12.1 within the earlier of (i) thirty (30) days or (ii) one-half of the
time during which Administrator, Parent or their Affiliates must respond to an
offer following the Group's receipt of the Notice, the option contained in this
Section 12.1 shall be deemed null and void and of no further force and effect,
and Administrator shall be free to assign the Agreement, sell all or
substantially all of the assets of Administrator or sell or transfer all of the
capital stock Administrator without the consent of the Group. No assignment
under this subsection (b) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

         Section 12.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 12.4 Additional Documents. Each of the parties hereto agrees to
execute any document or documents that may be reasonably requested from time to
time by the other party to implement or complete such party's obligations
pursuant to this Agreement.

         Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,
costs and expenses including, but not limited to, attorney's fees, costs and
expenses for trial, appellate proceedings and negotiations, in addition to any
other relief granted.

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group
and Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this
Agreement should be construed or deemed, by any governmental authority, agency
or court to constitute the practice of medicine, the performance of said act or
service by Administrator shall be deemed waived and forever unenforceable and
the provisions of this Section 12.6 shall be applicable. Neither party shall
claim or assert illegality as a defense to the enforcement of this Agreement or
any provision


                                       48
<PAGE>   54
hereof; instead, any such purported illegality shall be resolved pursuant to the
terms of this Section 12.6 and Section 12.9.

         Section 12.7 Parties In Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto. Except
as provided in Section 6.1(g), neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party hereto
or thereto any rights or remedies hereunder or thereunder.

         Section 12.8 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

         Section 12.9 Severability. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 12.10 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULE GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

         Section 12.11 No Waiver; Remedies Cumulative. No party hereto shall by
any act (except by written instrument pursuant to Section 12.3 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default in or breach of any of the terms
and conditions hereof. No failure to exercise, nor any delay in exercising, on
the part of any party hereto,. any right, power or privilege hereunder shall

         (b) Alternative Management Arrangements.

                  (i) If Administrator fails to perform, provide or arrange for
the services set forth in this Article III in a manner reasonably consistent
with commercially available services offered by third party providers of
physician practice management services of the type and scope offered by
Administrator, then the Group shall provide written notice of such event to
Administrator, Parent or their Affiliates, including reasonable evidence of such
commercially available services. Administrator shall deliver to the Group within
thirty (30) days after receipt



                                       9
<PAGE>   15
by Administrator of such written notice a written plan detailing the methods and
procedures Administrator, Parent or their Affiliates shall utilize to restore
the level of service contemplated by this Agreement. In the event Administrator
fails to restore the level of service contemplated by this Agreement in
accordance with such plan submitted or in any event within ninety (90) days, the
Group shall be entitled to reimbursement by Administrator for the reasonable
costs and expenses of obtaining such service on a temporary basis until such
time Administrator demonstrates its ability to perform such service at the level
contemplated by this Agreement. Nothing contained in this subsection (b)(i)
shall be construed to limit the Group's ability to provide notice of a Material
Administrator Default pursuant to Section 10.3(b) of this Agreement.

                  (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service
is construed or deemed to constitute the practice of medicine, Administrator
shall deliver to the Group notice of such an event. The Group shall be entitled
to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

         Section 3.2 General Administrative Services.

         (a) Exclusive Management Services; Scope of Services. Except as
provided in Exhibit 3.2(a), the Group hereby engages Administrator to serve as
its exclusive manager and administrator of non-medical business services
relating to the operation of the Practice, subject to matters reserved for the
Group or referred to the Joint Planning Board as herein contemplated, and
Administrator shall have all necessary authority and hereby agrees to perform
such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

         (b) Billing and Collection.

                  (i) Administrator shall, in the name of and on behalf of the
Group, bill patients, insurance companies, Managed Care Payors, and other
third-party payors and collect all fees for services rendered in connection with
the Practice at the Premises or any Practice Site(s) (including all fees
generated by both the Technical Operations and the Professional Operations), for
services performed outside the Practice for its hospitalized patients, and for
all other professional and Practice services. The Group hereby appoints
Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:



                                       10
<PAGE>   16
                           (A) to bill patients, insurance companies, Managed
Care Payors, and other third-party payors in the Group's name and on its behalf;

                           (B) to collect accounts receivable resulting from
such billing not otherwise purchased by Administrator (as provided for in
Section 3.2(e) hereof) in the Group's name and on its behalf;

                           (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                           (D) to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                           (E) to take possession of and endorse in the name of
the Group and deposit into the Deposit Account (and/or in the name of an
individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                           (F) upon the prior consent of the Group, which
consent shall not be unreasonably withheld or delayed, to initiate the
institution of legal proceedings in the name of the Group or a Physician
Employee to collect any accounts and monies owed to the Group or the Physician
Employee, to enforce the rights of the Group or the Physician Employee, as the
case may be, as creditor under any contract or in connection with the rendering
of any service, and to contest adjustments and denials by governmental agencies
(or their fiscal intermediaries) as third-party payors.

                  (ii) The Group hereby appoints Administrator as its true and
lawful attorney-in-fact to deposit into the Deposit Account all Professional
Revenues and Technical Revenues collected by Administrator as provided for in
this Section 3.2(b). The Group covenants, and shall cause all Physician
Employees and Physician Extender Employees to covenant, to forward any payments
received with respect to any Professional Revenues or Technical Revenues
generated for services provided by the Group or any of its Physician Employees
and Physician Extender Employees to Administrator for deposit. Administrator
shall have the right to withdraw funds from the Deposit Account and all owners
of the Deposit Account shall execute a revocable standing transfer order (the
"Transfer Order") under which the bank maintaining the Deposit Account shall
periodically transfer the entire balance of the Deposit Account to a separate
bank account owned solely by Administrator (the "Administrator Account"). The
Group and Administrator hereby agree to execute from time to time such documents
and instructions as shall be required by the bank maintaining the Deposit
Account and mutually agreed upon to effectuate the foregoing provisions and to
extend or amend such documents and instructions. Any action by the Group that
materially interferes with the operation of this Section, including but not
limited to, any failure to deposit or to have Administrator deposit any



                                       11
<PAGE>   17
Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit Account not authorized by the express
terms of this Agreement or any other written agreement executed by each of the
parties, or any revocation of or attempt to revoke the Transfer Order (otherwise
than upon expiration or termination of this Agreement), will constitute a breach
of this Agreement and will entitle Administrator, in addition to any other
remedies it may have at law or in equity, to seek a court ordered assignment of
the rights provided to Administrator pursuant to subparagraph (i) above.

                  (iii) All monies shall be accounted for by Administrator as
being distinctly attributable to the Group. The Group may perform the functions
or exercise the rights set forth in this Section 3.2(b) only with the prior
written consent of Administrator. The Group shall execute such documents in form
and substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c) Accounting. Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of
the Practice, and Administrator shall perform all bookkeeping and accounting
services necessary or appropriate for the efficient operation of the Practice,
including the maintenance, custody and supervision of business records, ledgers
and reports; the establishment, administration and implementation of accounting
procedures, controls and systems; and implementation and management of
computer-based management information systems. The Group and its authorized
representatives shall have the right to review all financial books and records
maintained by Administrator relating to the operation of the Practice and to the
cash management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the parties have
agreed herein. The purchase price shall be an amount equal to the aggregate face
amount of the accounts receivable being sold less contractual adjustments and



                                       12
<PAGE>   18
estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

         (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication
services and medical transcribing services; provided, however, that the Group
may elect to prepare its own Tax Returns, in which case, the cost of preparing
such Tax Returns in excess of $2,500 per annum shall be included in Excluded
Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group
containing a balance sheet, income statement and monthly operational reports
which detail payments, charges and accounts receivable statistics, monthly
reconciliation reports on cash management and any other financial reports
reasonably requested by a member of the Joint Planning Board designated by the
Group, which shall be delivered to the Group as soon as practicable, but no
later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

         (g) Records and Files.

                  (i) Administrator's Business and Financial Records. At all
times during and after the term of this Agreement, including any extensions or
renewals hereof, all business records, including but not limited to, business
agreements, books of account, personnel records, general administrative records
and all information generated under or contained in the management information
system pertaining to Administrator's obligations hereunder, and other business
information of Administrator of any kind or nature, except for patient medical
records and the Group's Records (as defined in subparagraph (ii) below), shall
be and remain the sole property of Administrator; provided that during and after
termination of this Agreement, the Group shall be entitled to reasonable access
to such records and information, including the right to obtain copies thereof in
any media reasonably requested by the Group, for any purpose related to patient
care or the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years. Administrator hereby agrees
to preserve the confidentiality of such patient medical records and to use the
information in such records only for the limited purposes necessary to perform
management services and, within the limits of its responsibilities hereunder, to
ensure that provision is made for appropriate care for patients of the Practice.



                                       13
<PAGE>   19
                  (ii) The Practice's Business and Financial Records. At all
times during and after the term of this Agreement, the business agreements,
financial, operational, corporate and personnel records and information relating
exclusively to the business and activities of the Group and patient medical
records and charts (hereinafter referred to as the "Group's Records") shall be
and remain the sole property of the Group.

                  (iii) Access to Records. At all times during and after the
term of this Agreement, each party and its authorized agents shall be entitled,
upon request and with reasonable advance notice, to obtain access (within not
more than 30 days following receipt of such notice by the other party or
parties) to all records of the other party directly related to the performance
of such party's obligations pursuant to this Agreement; provided, however, that
such right shall not allow for access to patient, medical and other records that
must be kept confidential as required by law. Either party, at its expense,
shall have the right to make copies in any media of any records to which it has
access pursuant to this subparagraph (iii).

                  (iv) Compliance with Law. The management of all files and
records by Administrator and the Group shall comply with all applicable federal,
state and local statutes and regulations.

         (h) Collections. Subject to the consent requirement contained in
Section 3.2(b)(i)(F), Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees and
pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

         Section 3.3 Facilities.

Premises that are described in Exhibit 3.3(a) attached hereto and such other
improvements made by Administrator or Parent for the use of the Group hereunder.

property necessary or appropriate for the efficient operation of the Practice
acquired by Administrator or Parent (subject to review and approval of the Joint
Planning Board) for the use of the Group pursuant to the terms hereof
(collectively, the "Personal Property"). Administrator shall maintain the
Personal Property in good condition and make or cause to be made all necessary
repairs thereto.


                                       14
<PAGE>   20
         (c) Expenses. All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the
Premises and the Personal Property, including, without limitation, all
reasonably necessary costs of repairs, maintenance and improvements, utility
expenses (i.e., telephone, electric, gas and water), janitorial services, refuse
disposal, real or personal property lease cost payments and expenses, interest,
refinancing expenses, depreciation, loss on disposition of assets, taxes and
casualty, liability and other insurance, shall be included in Practice Expenses.
To the extent the Premises or Personal Property are used in connection with the
Professional Operations, the costs and expenses associated with such usage shall
be allocated between Professional Expenses and Technical Expenses as approved by
the Joint Planning Board.

         (d) Disposition. Subject to provisions contained in existing agreements
to which Administrator or Parent is or becomes a party and, where necessary and
appropriate for the efficient operation of the Practice, nothing herein shall be
construed as precluding Administrator or Parent from selling, leasing or
otherwise disposing of all or any part of the Premises, Personal Property, real
property, improvements, trade names, trademarks and other intangible property;
provided, however, any such sale, lease or disposition shall be subject to the
prior review and approval of the Joint Planning Board and shall not eliminate or
diminish Administrator's obligations hereunder.

         (e) No Warranties or Representations. The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

         Section 3.4 Acquisition and Assistance.

         (a) Employment of Physicians. Subject to consultation with the Joint
Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice. Subject to
consultation with the Joint Planning Board, in the event that a decision is made
by the Group to pursue the employment of selected physicians, if requested by
the Group, Administrator will provide recruiting, consulting, negotiating and
other advisory services in connection with such transaction. Notwithstanding the
preceding, as set forth in and subject to the provisions of Section 4.1 hereof,
the Group shall have complete control of and responsibility for the hiring of
all Physician Employees and Physician Extender Employees.

         (b) Acquisitions. In the event that the Group contemplates acquiring or
affiliating with a physician group, practice or other entity, and such
acquisition or affiliation involves the use or expenditure of Administrator's
and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a
result of such an acquisition or affiliation including, without limitation,
capital and personnel (collectively, the "Resources"), then the Group shall
first consult with the Joint Planning Board and Administrator, and any decision
to make such affiliation or acquisition shall


                                       15
<PAGE>   21
be subject to prior approval of Administrator, which decision of the
Administrator shall be provided to the Group in a reasonable and timely manner
following satisfactory review of the physician group, practice or other entity
to be acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto. If such contemplated acquisition or affiliation does not
involve the use or expenditure of any of Administrator's and/or Parent's
Resources, then such decision shall be in the sole discretion of the Group.
Notwithstanding any provision contained herein to the contrary, any person or
entity with which the Group affiliates or acquires shall be subject to the terms
and conditions of this Agreement. If a decision is made to proceed with any
affiliation or acquisition of a physician group or practice, the Group may seek
from Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

         Section 3.5 Financial Planning and Budgeting.

         (a) Budgeting. Administrator shall collaborate with the Group and the
Joint Planning Board in the preparation of all annual capital and operating
budgets. These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors. For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board. The
projected annual operating budget for each subsequent year shall be subject to
the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice. For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

         (b) Capital Expenditures. Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

                  (i) Budgeted Expenditures. All budgeted capital expenditures
and improvement projects shall be subject to final review and approval by the
Joint Planning Board prior to the making of any actual expenditure. Such review
and approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.


                                       16
<PAGE>   22
                  (ii) Non-Budgeted Expenditures. Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared by
the Joint Planning Board in consultation with the Group and Administrator. All
requests for non-budgeted capital expenditures and improvements at or for the
benefit of the Practice in excess of either $75,000 individually or an aggregate
amount equivalent to $2,500 multiplied by the number of Full-time Physician
Employees employed at the time the capital budget for such Group for the
applicable year is determined (provided, however, that such aggregate amount
shall not exceed $250,000 for any calendar year) must be approved by the Board
of Directors of Parent or by any committee specifically designated by the Board
of Directors of Parent for such purposes.

         (c) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors"). Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning


                                       17
<PAGE>   23
Board, be the responsibility of the Group. Notwithstanding the preceding
language, if a contract or relationship between any Managed Care Payor and the
Group involves or affects a contract or relationship with any other physician
group or practice serviced or managed by Administrator, Parent or any of their
Affiliates (the "Other Practices") and a consensus among the Group and the Other
Practices cannot be reached regarding the contract or relationship, then the
ultimate decision as to the approval, disapproval, termination or amendment of
such contract or relationship involving the Group, the Other Practices and such
Managed Care Payor shall be determined by the affirmative vote of the Physician
Board Members (as defined below) who hold a majority of the Group Voting Power
(as defined below). For purposes of this Section 3.7, (i) the term "Physician
Board Members" shall mean (a) those members appointed by the Group who serve on
the Joint Planning Board and (b) those persons appointed by the Other Practices
who serve on the Other Practices' joint boards (in a similar capacity to the
Joint Planning Board) as part of their contractual relationship with Parent,
Administrator or any of their Affiliates, and (ii) the term "Group Voting Power"
shall mean the total voting percentage which may be cast by the Physician Board
Members on a collective basis, with the percentage of votes able to be cast by
any Group or Other Practice, as applicable, shall be equal to the quotient
determined by dividing (x) the total estimated annual professional revenues to
be generated by the Group from such Managed Care Contract as determined by
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion, by (y) the total estimated annual professional revenues to be
generated by the Group and all Other Practices from such Managed Care Contract
as determined by the Administrator, Parent or their Affiliates, as appropriate,
in its sole discretion.

         Section 3.8 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.9 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and advertising programs shall be
conducted in compliance with applicable standards of medical ethics, laws and
regulations.

<PAGE>   24
         Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program
shall be included in Administrator Expenses; provided, however, that any
expenses related to such program that are incurred for services provided solely
for the direct benefit of the Practice shall be included in Practice Expenses.

         Section 3.11 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by
the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

         Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.


                                   ARTICLE IV

                            Obligations of the Group

         Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender
Employees, and other employees who may have malpractice exposure or liability,
are insurable and by participating in an ongoing risk management program.

         Section 4.2 Professional Services. The Group shall provide professional
services to its patients in compliance at all times with ethical standards,
laws, rules and regulations applicable to the operations of the Practice, the
Physician Employees and Physician Extender Employees. The Group shall ensure
that each Physician Employee and each Physician Extender Employee has all
required licenses, credentials, approvals or other certifications to perform his
or her duties and services for the Practice and, in the event that the Group
becomes aware of any disciplinary actions or medical malpractice actions
initiated against any Physician Employee or Physician Extender Employee, the
Group shall promptly inform Administrator of such action and the underlying
facts and circumstances. If required by applicable law, any state or federal
regulatory agency or any contractual obligations, the Group shall carry out a
program to monitor the quality of medical care practiced at the Practice;
provided, however, that the preceding language shall not limit the Group's
obligation to participate in or comply with any programs established by
Administrator or Parent for purposes of ensuring that the Group complies with
applicable law. The Group shall employ Physician Employees and Physician
Extender Employees as is necessary to provide efficient medical care to patients
of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery
items on prepaid Managed Care Contracts which are authorized and permitted by
such contracts. A copy of such agreements and any amendment thereto shall be
provided to Administrator for review no later than thirty (30) days prior to the
proposed effective date thereof.

         Section 4.4 Group's Internal Matters. The Group shall be responsible
for matters involving its corporate governance, employees and similar internal
matters, including, but not limited to, preparation and contents of such reports
to regulatory authorities governing the Group that the Group is required by law
to provide, distribution of professional fee income among the Group Physician
Stockholders, disposition of the Group's property and stock (subject to any


                                       20
<PAGE>   26
restrictions contained herein), hiring and firing of its employees, licensing
and implementing all compliance plans and procedures as described in Section
4.6. Except for the expenses attributable to the distribution of professional
fee income among the Group Physician Stockholders, which will be included in
Excluded Practice Expenses, the costs incurred in connection with the foregoing
matters shall be Practice Expenses.

         Section 4.5 Name. Administrator agrees that the Group shall be entitled
to use on a non-exclusive and non-transferable basis for the term of this
Agreement the names set forth on Schedule 4.5 as may be necessary or appropriate
in the performance of the Group's services and obligations hereunder.

         Section 4.6 Compliance with Laws. The Group shall, and shall use its
best efforts to cause the Physician Employees, Physician Extender Employees and
other employees of the Group to, comply with all applicable federal, state and
local laws, rules, regulations and restrictions in the conduct of the Practice's
business. Without limiting the generality of the foregoing, the Group shall
comply and shall cause each Physician Employee, Physician Extender Employee and
other employee of the Group to comply, with all laws applicable to the operation
of the Practice in the generation, transportation, treatment, storage, disposal
or other handling of radioactive, medical, biological or hazardous materials or
waste, and the Group shall not, and shall use its best efforts to prohibit any
Physician Employee, Physician Extender Employee and any employee of the Group

payment may be made in whole or in part by Medicare or Medicaid, or (ii) in

                              Joint Planning Board

         Section 5.1 Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy is counted;
provided, however, that no proxy shall be valid after the expiration of eleven
(11) months from the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2 Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

         (a) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital

the particular project and the Group as a whole.

         (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess
of five percent (5%) to the annual capital or operating budgets.

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

by the Practice.

         (e) Ancillary Services and Fees. The Joint Planning Board shall approve
Practice-provided non-medical ancillary services (including, without limitation,
fees for technical services which do not generate Professional Revenues) based
upon the pricing, access to, and quality of such services and shall review and
adopt the fee schedule for all ancillary services.

         (f) Provider and Payor Relationships. Subject to Section 3.7, decisions
regarding the establishment or maintenance of relationships with institutional
health care providers and payors shall be approved by the Group after
consultation with the Joint Planning Board.

         (g) Strategic Planning. The Joint Planning Board shall develop a plan

priority of capital expenditures in accordance with Section 3.5(b) hereof.

         (i) Provider Hiring. The Joint Planning Board shall consult with the

Board. The Group agrees that, unless the following are approved in advance by
the Joint Planning Board and such act of the Joint Planning Board includes the
approval by both of the members designated by Administrator, it shall take no
action or implement any decision that would (i) require Administrator to expend
funds or incur obligations beyond those set forth under Sections 3.5 or 5.2 of
this Agreement; (ii) have a material adverse effect on the amount of
Administrator's management fee under Article VII; or (iii) otherwise have a
material adverse effect on Administrator's financial interests under this

approved by the members holding at least a majority of the voting power of the
Joint Planning Board. No action of the Joint Planning Board shall be effective
unless authorized by the members holding a majority of the voting power of the
Joint Planning Board present or represented by proxy at the applicable meeting.
In the event that a matter cannot be resolved by the Joint Planning Board due to
a tie vote, and no compromise can be reached, then either (x) the Board of
Directors of Parent or (y) a committee designated by the Board of Directors of
Parent containing at least one (1) physician member will make a final
determination on the matter in dispute provided that both the Group and
Administrator shall have had an opportunity to make a presentation to the Board
of Directors of Parent or a committee thereof, as applicable. A quorum of the
Joint Planning Board shall consist of the members holding a majority of the
voting power of the Joint Planning Board, present in person, by telephone, or by
proxy and the quorum must remain for the duration of the meeting.

         Section 5.4 Joint Planning Board Meetings. Meetings of the Joint
Planning Board may be held by telephone or similar communication equipment so
long as all members participating in a meeting can hear and speak to each other.

(15) business days following each meeting.

members may determine.

         (b) Special Meetings. A special meeting of the Joint Planning Board may
be called by fifty percent (50%) of the votes.

         (c) Notice Requirement. A member calling a special meeting must provide
all other members with ten (10) days' advance written or telephonic notice.
Notice must be given or sent to the member's address or telephone number as
shown on the records of the Joint Planning Board. Notice may be delivered
directly to each member or to a person at the member's principal place of
business who would reasonably be expected to communicate that notice promptly to
the member.

         (d) Waiver of Notice Requirement.

                  (i) Written Waiver, Consent or Approval. Notice of a special
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the special meeting. Such waiver,
consent or approval need not specify the purpose of the special meeting. All
such waivers, consents, and approvals shall be filed with the Joint Planning
Board records or made a part of the minutes of the special meetings.

                  (ii) Failure to Object. Notice of special meeting need not be
given to any member who attends the special meeting and does not protest before
or at the commencement of the special meeting such lack of notice.

                  (iii) Quorum. The smallest number of members that hold votes
that exceed fifty percent (50%) of all voting power shall constitute a quorum of
the Joint Planning Board.

                  (iv) Proxies. The Joint Planning Board shall provide for the

Information, without the prior written consent of Administrator, Parent and
their Affiliates; unless (i) such information becomes known or available to the
public generally through no wrongful act of the Group or its employees or (ii)
disclosure is required by law or the rule, regulation or order of any
governmental authority under color of law; provided, that prior to disclosing
any Administrator's Confidential and Proprietary Information pursuant to this
clause (iii), the Group shall, if possible, give prior written notice thereof to
Administrator, Parent and their Affiliates and provide such parties with the
opportunity to contest such disclosure. The Group shall take all necessary and
proper precautions against disclosure of any Administrator's Confidential and
Proprietary Information to unauthorized persons by any of its officers,
directors, employees or agents. All officers, directors, employees, and agents
of the Group who will have access to all or any part of the Administrator's
Confidential and Proprietary Information will be required to execute an
agreement upon request, valid under the law of the jurisdiction in which such
agreement is executed, and in a form acceptable to Administrator, Parent and
their Affiliates and its counsel, committing themselves to maintain the
Administrator's Confidential and Proprietary Information in strict confidence
and not to disclose it to any unauthorized person or entity. Upon termination


                                       29
<PAGE>   35
of this Agreement for any reason, the Group and their employees shall cease all
use of any of the Administrator's Confidential and Proprietary Information and
shall execute such documents as may be reasonably necessary to evidence their
abandonment of any claim thereto.

                  (iii) Return of Materials. In the event of any termination of
this Agreement for any reason whatsoever, or at any time upon the request of
Administrator, Parent or their Affiliates, the Group will promptly deliver or
cause to be delivered to Administrator, Parent and their Affiliates all
documents, data and other information in their possession that contains any
Administrator's Confidential and Proprietary Information regarding
Administrator, Parent and their Affiliates. The Group shall not take or retain
any documents or other information, or any reproduction or excerpt thereof,
containing any Administrator's Confidential and Proprietary Information, unless
otherwise authorized in writing by the party possessing such Administrator's
Confidential and Proprietary Information. In the event of termination of this
Agreement, the Group will deliver to Administrator, Parent and their Affiliates
all documents and data pertaining to Administrator's Confidential and
Proprietary Information of the other parties not otherwise purchased as part of
the Purchased Assets.

         (f) Third Party Beneficiaries. The members of the APPI Group not party
to this Agreement are hereby specifically made third party beneficiaries of this
Section 6.1, with the power to enforce the provisions hereof.

         Section 6.2 Restrictive Covenants. The Group shall obtain and enforce
formal agreements with each Physician Employee who is either (i) a Group
Physician Stockholder or (ii), to the extent permitted under applicable law, a
Full-time Physician Employee which each contain certain restrictive covenants
thereof pertaining to covenants not to compete and/or solicit with and not to
divulge the Confidential and Proprietary Information of any member of the APPI
Group or the Practice (the "Restrictive Covenants"). Except as otherwise
approved by the Joint Planning Board, each Group Physician Stockholder or
Full-time Physician Employee shall agree, during the term of his/her employment
or contractor agreement with the Practice and for a period of twenty-four (24)
months after any termination of such agreement: (i) not to establish, operate or
provide professional radiology services at any office, practice, hospital or
health care facility providing services substantially similar to those provided
by the Practice pursuant to this Agreement within 15 miles of any location of
any Practice Site(s) and (ii) to be bound by non-solicitation, noncompetition
and nondisclosure of confidential/proprietary information and engagement of
Administrator covenants similar to those applicable to the Group as contained in
Section 6.1 hereof. Except as otherwise approved by the Joint Planning Board,
each Group Physician Stockholder or Full-time Physician Employee shall agree
that during the term of his/her employment or contractor agreement with the
Group (w) not to practice radiological medicine other than at the Premises or
such other location or Practice Site(s) as approved by the Joint Planning Board;
(x) to devote substantially all of his or her professional time, effort and
ability to the Practice; (y) to request in writing and receive in writing prior
approval from the Joint Planning Board to engage in any outside medical
activities; and (z) to turn over to the Practice, to be included in Professional
Revenues attributed to the Practice, any income derived by such Group Physician
Stockholder or Full-time Physician Employee from any outside medical activity or
related source from the following medically-related activities: teaching,
consulting,


                                       30
<PAGE>   36
medical research, inventions developed utilizing the Group's or the Practice's
time and material, testimony for litigation, and insurance examinations. The
Group shall not materially amend, alter or otherwise change any term or
provision of any Stockholder Employment Agreement or Physician Employee
Employment Agreement relating to the foregoing covenants in this Section 6.2
without the prior written consent of Administrator; notwithstanding the
foregoing, any such amendment, alteration or change shall not be inconsistent
with the terms or provisions of this Agreement. Following termination of this
Agreement, the Group shall not amend, alter or otherwise change any term or
provision of the Restrictive Covenants, unless such provisions are no longer in
force and effect pursuant to the terms of the applicable Stockholder Employment
Agreement or Physician Employee Employment Agreement at the time of termination
of this Agreement. In the event the Purchase Assets are acquired by the Group
pursuant to Article X, the obligation of the Group to enforce Restrictive
Covenants shall be limited to enforcement of non-solicitation and nondisclosure
of confidential/proprietary information covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Stockholder Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Stockholder Employment
Agreements and, to the extent permitted under applicable law, the Physician
Employee Employment Agreements, upon the request of Administrator, the Group
shall assign to Administrator such causes of action and/or other rights it has
related to such breach or default and shall cooperate with and provide
reasonable assistance to Administrator with respect thereto; in which case, all
costs and expenses incurred in connection therewith shall be borne by
Administrator and shall be included in Administrator Expenses, and Administrator
shall be entitled to all damages and other amounts recovered thereby. In the
event the Purchase Assets are acquired by the Group pursuant to Article X, the
obligation of the Group to enforce Restrictive Covenants shall be limited to
enforcement of non-solicitation and nondisclosure of confidential/proprietary
information covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period,


                                       31
<PAGE>   37
scope of activity restricted and/or the geographical area applicable to such
provision of the Restrictive Covenants or this Article VI. The invalidity or
non-enforceability of any provision of the Restrictive Covenants or this Article
VI in any respect shall not affect the validity or enforceability of the
remainder of the Restrictive Covenants or this Article VI or of any other
provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Stockholder or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Stockholder or Full-time Physician Employee from the restrictive
covenants contained in Section 6.2, above. In the event the Group elects to
release such Group Physician Stockholder or Full-time Physician Employee, the
Group hereby covenants that it shall obtain a formal agreement between each
Group Physician Stockholder or Full-time Physician Employee, as the case may be,
and Administrator which provides that, for a period of two (2) years following
termination of any employment agreement with the Group, such Group Physician
Stockholder or Full-time Physician Employee agrees to (a) engage Administrator
as the sole and exclusive manager and administrator of the non-medical functions
and services of said Group Physician Stockholder's or Full-time Physician
Employee's medical practice and (b) pay to Administrator the identical amount
[NY only] of revenues paid by the Group to the Administrator attributable to
such Group Physician Stockholder or Full-time Physician Employee derived from
such Group Physician Stockholder's or Full-time Physician Employee's performance
of professional medical services within 15 miles of any Practice Site.

         Section 6.6 Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary
information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and


                                       32
<PAGE>   38
work effort required and (y) the Group shall not be required to employ any
Radiologist previously associated with such Professional Service Opportunity.

         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half of the time during which the
Administrator, Parent or their Affiliates must respond to an offer described in
the Administrator's Notice, the Group shall deliver to Administrator a written
notice stating whether or not the Group elects to accept or reject the New
Professional Service Opportunity which election shall be binding on the Group.
If the Group does not elect to exercise the right or fails to provide the notice
to Administrator within the time frame herein provided, Administrator shall be
released from the right of first offer with respect to that particular New
Professional Service Opportunity. Prior to consummating any asset acquisition,
merger or other consolidation of any Radiologist, group of Radiologists, or
professional corporation or association (or other professional entity) whose
owners are Radiologists within any Secondary Service Area, Administrator shall
first consult with the Joint Planning Board.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service
Opportunity as contemplated in subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.


                                       33
<PAGE>   39
             "Professional Service Opportunity" shall mean any opportunity to

following the Acquisition Effective Date, that area which extends ten (10) miles
beyond the boundary of any Primary Service Area and (ii) during the remaining

         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.


                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on


                                       34
<PAGE>   40
Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates based
upon available information for such month, and adjustments to the estimated
payments shall be made to reconcile final amounts due under Section 7.1 on the
next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee


                                       35
<PAGE>   41
and to other related provisions of this Agreement shall be a joint decision of
the parties, shall be memorialized in a written amendment to this Agreement, and
shall be based upon the methodology used to generally determine Services Fees
hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

         (a)      payment of all accrued Practice Expenses for the prior month
                  (subject to the proviso in the preceding sentence;

         (b)      payment of the accrued Service Fee for the prior month;

         (c)      payment of outstanding balance of all amounts advanced to the
                  Group, through the end of the prior month, and applicable
                  interest thereon (as contemplated in Section 7.3); and

         (d)      payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).


                                  ARTICLE VIII

                                     Records

         Section 8.1 Records. All records relating in any way to the operation
of the Practice (other than Group Records) shall, subject to the obligations of
the Practice to maintain patient medical records pursuant to Section 3.2(g), at
all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter, the
Group or its agents shall have reasonable access during normal business hours to
the Group's and Administrator's personnel and financial records relating to the
Practice, including, but not limited to, records of collections, expenses and
disbursements as kept by Administrator in


                                       36
<PAGE>   42
performing Administrator's obligations under this Agreement, and the Group may
copy any or all such records.


                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1 Insurance to be Maintained by the Group.

         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.


                                       37
<PAGE>   43
         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.

         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5 Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its shareholders, employees
and/or subcontractors (other than Administrator, Parent, Affiliates or their
employees, officers, directors, agents, attorneys and consultants) during the
term of this Agreement. Provided, however, that in the event an indemnification
obligation under the preceding sentence arises as of the result of any act or
omission of a person who is an officer, shareholder or other equity holder,
director, employee, agent, attorney or consultant of Administrator, Parent or
any of their Affiliates (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
the Group's indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or
incurred, that are caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts or omissions by Administrator, Parent or Affiliates and/or any of
their respective shareholders, employees and/or subcontractors (other than the
Group or its employees) during the term of this Agreement. Provided, however
that


                                       38
<PAGE>   44
in the event an indemnification obligation under the preceding sentence arises
as a result of any act or omission of a person who is an officer, shareholder or
other equity holder, director, employee, agent, attorney or consultant of the
Group (other than in connection with the activities of the Joint Planning
Board), such person shall not be entitled to indemnification in connection
therewith and any other adjustment as is equitable shall be made to
Administrator's or Parent's indemnification obligation arising thereby.

                              Term and Termination

         Section 10.1 Term of Agreement. This Agreement shall commence on the
date hereof and shall expire on the 40th anniversary hereof unless earlier
terminated pursuant to the terms of either Section 10.3 or Section 10.4 or
automatically extended pursuant to the terms of Section 10.2.

         Section 10.2 Extended Term. Unless earlier terminated as provided for
in either Section 10.3 or Section 10.4, the term of this Agreement shall be
automatically extended for additional terms of five (5) years each, unless
either party delivers to the other party, not less than twelve (12) months nor
earlier than fifteen (15) months prior to the expiration of the preceding term,
written notice of such party's intention not to extend the term of this
Agreement.

         Section 10.3 Termination by the Group. The Group may, in its sole
discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not


                                       39
<PAGE>   45
the obligation, to cure any Material Adminstrator Default. Notwithstanding
anything to the contrary in this Agreement, following receipt by Administrator
of the notice of a Material Administrator Default and until such Material
Administrator Default shall be cured, the Group may take such action as may be
reasonably required to cover such Material Administrator Default so as to
maintain for the Group the same level of service as before the Material
Administrator Default, without prejudicing in any way the Group's other rights
and remedies, and may offset all of its costs from the amounts which may
otherwise be due to Administrator under this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that


                                       40
<PAGE>   46
individual from participating in or from receiving reimbursement under any
program funded by the federal government or by any state government,
notwithstanding any available post-sanction remedies, or (4) is otherwise
disciplined by any licensing, regulatory or professional entity or institution,
the result of any of which event does or is reasonably expected to materially
adversely affect the Practice, the result of any of which event described in
subparagraphs (1) through (4) above, in the absence of termination of a
Physician Employee or a Physician Extender Employee or other action of the Group
to monitor and cure such act or conduct by such employee, does or reasonably
would be expected to materially and adversely affect the Practice or the Group.
Notwithstanding anything to the contrary in this Agreement, following receipt by
the Group of the notice of a Material Group Default, and until such Material
Group Default shall be cured, the Administrator may take such action as may be
reasonably required to cover such Material Group Default so as to maintain for
the Administrator the same level of service at the Premises as before the
Material Group Default, without prejudicing in any way Administrator other
rights and remedies, and may offset all of its costs of cover from amounts which
may otherwise due to the Group under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Stockholders and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
(with the exception of Hector Correa, Nancy Sussman, M.D., or Herbert Z. Geller)
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee [or Physician Extender Employee] that intends to
retire prior to expiration of such five-year period, then such Physician
Employee or Physician Extender Employee shall not be counted for purposes of
determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator and/or Parent, the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or their
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's or their Affiliates' accounting and financial records (the "Purchase
Assets"), including, but not limited to, without duplication, (i) all equipment,
furniture, fixtures, furnishings, inventory, supplies, improvements, additions
and leasehold improvements utilized by the Practice, (ii) any real estate owned
by Administrator, Parent or Affiliates that is occupied by or used primarily for
the benefit of the Practice, (iii) all unamortized intangible assets (including,
without limitation, goodwill) set forth on the financial statements of
Administrator, Parent or their Affiliates used solely in connection with the
Practice or otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and their Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c) Purchase Price. The Purchase Price shall be the lesser of (i) Fair
Market Value of the Purchase Assets subject to the assumption of the Practice
Related Liabilities or (ii) the value of the Actual Consideration (defined
below)(alternatively, the "Purchase Price"); provided, however, the Purchase
Price shall not be less than the net book value of the Purchase Assets at the
Termination Date. The Purchase Price shall be paid pursuant to Section 10.7. For
purposes of this subparagraph (c), the term "Actual Consideration" shall mean
(i) cash consideration paid to the Group pursuant to the Acquisition Agreement
and (2) an amount equal to the number of shares of Parent Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, reorganizations,
or any similar transaction whereby the Parent Common Stock is increased or
decreased or exchanged for a different number or kind of securities) issued
pursuant to the Acquisition Agreement multiplied by the fair market value of
Parent Common Stock immediately prior to the time that a Termination Notice is
provided pursuant to Section 10.7. The Purchase Price shall be appropriately
adjusted to offset and account for any monetary obligations of the Group or
Administrator owing to the other as provided herein.

         (d) Exercise of Option.

                  (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                  (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

         (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at the Purchase Closing, Administrator and/or its Affiliates, as the case
may be, shall transfer and assign the Purchase Assets to the Group, and in
consideration therefor, the Group shall (a) pay to Administrator, Parent and/or
their Affiliates an amount in cash or, at the option of the Group (subject to
the conditions set forth below), Parent Common Stock (valued pursuant to Section
10.6(c) hereof), or some combination of cash and Parent Common Stock equal to
the Purchase Price and (b) assume the Practice Related Liabilities. The
structure of the transaction set forth in this Section 10.7 shall, if possible,
be structured as a tax-free transaction under applicable law. Each party shall
execute such documents or instruments as are reasonably necessary, in the
opinion of each party and its counsel, to effect the foregoing transaction. The
Group shall, and shall use its best efforts to cause each shareholder of the
Group to, execute such documents or instruments as may be necessary to cause the
Group to assume the Practice Related Liabilities and to release Administrator,
Parent and/or their Affiliates, as the case may be, from any liability or
obligation with respect thereto. In the event the Group desires to pay all or a
portion of the Purchase Price in shares of Parent Common Stock, such transaction
shall be subject to the satisfaction of each of the following conditions:


                                       43
<PAGE>   49
         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims, proxies, options, stockholders' agreements
and encumbrances (not including any applicable securities restrictions and
lock-up arrangements with the Parent or any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain financing for such acquisition but is unable to
obtain such financing and (iii) there is either a Material Administrator Default
pursuant to Section 10.3(a) or (c) or a Material Group Default pursuant to
Section 10.4(b) triggering a sale of the Purchase Assets, the Group shall be
entitled to obtain financing from Administrator, Parent and/or their Affiliates
but only for the difference between the Fair Market Value of the Purchase Assets
and the net book value of the Purchase Assets. The terms of such financing shall
be for a five (5) year period at an interest rate equal to the prime rate (as
published in the Wall Street Journal) plus four percent (4%) or such lesser rate
as is required to be in conformance with all applicable state and federal law.
In the event the Group is entitled to obtain financing from Administrator,
Parent and/or their Affiliates, the Group shall execute and deliver to
Administrator, Parent and/or their Affiliates all such documentation necessary
and appropriate to effectuate the financing transaction including, without
limitation, a secured promissory note, security agreement and financing
statements and such documentation shall contain such representations, warranties
and conditions customary to a secured transaction of this size.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator, Parent and/or their Affiliates to the
Group or the Group to the Administrator, Parent and/or their Affiliates


                                       44
<PAGE>   50
(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

         (a) Administrator, Parent and/or their Affiliates shall use their best
efforts to cooperate with the Group for the appropriate transfer of management
services.

         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.

         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.


                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

         Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means


                                       45
<PAGE>   51
set forth in Section 11.1 and prior to commencing an arbitration procedure
pursuant to this Article XI, the parties shall meet to discuss and consider
other alternative dispute resolution procedures other than arbitration,
provided, however that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including rules of
evidence and procedure. If at any time prior to the rendering of the decision by
the arbitrator (or pursuant to such other alternative dispute resolution
procedure) as contemplated in this Article XI to the extent a party makes a
written offer to the other party proposing a settlement of the matter(s) at
issue and such offer is rejected, then the party rejecting such offer shall be
obligated to pay the costs and expenses (excluding the amount of the award
granted under the decision) of the party that offered the settlement from the
date such offer was received by such other party if the decision is for a dollar
amount that is less than the amount of such offer to settle. Notwithstanding the
foregoing, the terms and provisions of this Article XI shall not preclude any
party hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

         Section 11.3 Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among Administrator and the Group arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within 30 days of notice
by a party to the other of its desire to seek arbitration under this Article XI
one arbitrator mutually acceptable to Administrator and the Group to hear and
decide all such claims under this Article XI. If such matter or action involves
health-care issues, then the arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators proposed shall be impartial
and independent of all parties. If the parties cannot agree on the selection of
an arbitrator within said 30-day period, then any party may in writing request
the judge of the United States District Court for the Southern District of New
York (White Plains) senior in term of service to appoint the arbitrator and,
subject to this Article XI, such arbitrator shall hear all arbitration matters
arising under this Article XI.

         Section 11.4 Applicable Rules.

         (a) Each arbitration hearing shall be held at a place in Weschester or
Rockland Counties, New York, acceptable to the arbitrator. The arbitration shall
be conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof. The decision of the arbitrator shall be reduced to writing and shall be
binding on the parties and such decision shall contain a concise statement of
the reasons in support of such decision. Judgment upon the award(s) rendered by
the arbitrator may be entered and execution had in any court of competent
jurisdiction or application may be made to such court for a judicial acceptance
of the award and an order of enforcement. The charges and expenses of the
arbitrator shall be shared equally by the parties to the hearing.


                                       46
<PAGE>   52
         (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI. In
fulfilling his duties with respect to determining the amount of any loss, the
arbitrator may consider such matters as, in the opinion of the arbitrator, are
necessary or helpful to make a proper valuation. The arbitrator may consult with
and engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

         (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.

         (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e) All privileges under New York and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying New York law.


                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment.

         (a) Administrator shall have the right to assign its rights hereunder
to Parent or any direct or indirect wholly-owned subsidiary of Administrator or
Parent (that remains a wholly-owned subsidiary of Administrator or Parent) or to
a financial institution as collateral security for the indebtedness of Parent,
Administrator or their Affiliates without the consent of the Group. No
assignment under subsection (a) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         (b) Administrator, Parent and their Affiliates shall provide notice to
the Group of Administrator's intent (i) to assign this Agreement (other than as
permitted in Section 12.1(a) herein), (ii) sell all or substantially all of the
assets of Administrator or (iii) effectuate a consolidation, merger or sale of a
majority of the capital stock of Administrator as soon as practicable following
a decision by the Parent's and Administrator's respective boards of directors to
seek such assignment or sale. The assignment of this Agreement (other than as
permitted in Section 12.1(a)), the sale of all or substantially all of the
assets of Administrator by Parent or a consolidation, merger or sale of a
majority of the capital stock of Administrator


                                       47
<PAGE>   53
shall not be permitted unless Administrator shall give written notice to the
Group stating the party who made the offer and specifying the purchase price
offered (the "Notice"). The Group shall have the option to repurchase the
Purchase Assets on the same terms and conditions set forth in the Notice. In the
event the Group fails to provide written notice to Administrator of its intent
to exercise its option to repurchase the Purchase Assets pursuant to this
Section 12.1 within the earlier of (i) thirty (30) days or (ii) one-half of the
time during which Administrator, Parent or their Affiliates must respond to an
offer following the Group's receipt of the Notice, the option contained in this
Section 12.1 shall be deemed null and void and of no further force and effect,
and Administrator shall be free to assign the Agreement, sell all or
substantially all of the assets of Administrator or sell or transfer all of the
capital stock Administrator without the consent of the Group. No assignment
under this subsection (b) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

         Section 12.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 12.4 Additional Documents. Each of the parties hereto agrees to
execute any document or documents that may be reasonably requested from time to
time by the other party to implement or complete such party's obligations
pursuant to this Agreement.

         Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,
costs and expenses including, but not limited to, attorney's fees, costs and
expenses for trial, appellate proceedings and negotiations, in addition to any
other relief granted.

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group
and Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this
Agreement should be construed or deemed, by any governmental authority, agency
or court to constitute the practice of medicine, the performance of said act or
service by Administrator shall be deemed waived and forever unenforceable and
the provisions of this Section 12.6 shall be applicable. Neither party shall
claim or assert illegality as a defense to the enforcement of this Agreement or
any provision


                                       48

hereof; instead, any such purported illegality shall be resolved pursuant to the
terms of this Section 12.6 and Section 12.9.

         Section 12.7 Parties In Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto. Except
as provided in Section 6.1(g), neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party hereto
or thereto any rights or remedies hereunder or thereunder.

         Section 12.8 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

         Section 12.9 Severability. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 12.10 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULE GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

         Section 12.11 No Waiver; Remedies Cumulative. No party hereto shall by
any act (except by written instrument pursuant to Section 12.3 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default in or breach of any of the terms
and conditions hereof. No failure to exercise, nor any delay in exercising, on
the part of any party hereto,. any right, power or privilege hereunder shall
operate as a waiver thereof. No single or partial exercise of any right, power
or privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. No remedy set forth in this
Agreement or otherwise conferred upon or reserved to any party shall be
considered exclusive of any other remedy available to any party, but the same
shall be distinct, separate and cumulative and may be exercised from time to
time as often as occasion may arise or as may be deemed expedient.

for the services set forth in this Article III, and the costs, fees, expenses
and other disbursements incurred by Administrator or Parent in connection
therewith shall be included in Practice Expenses, except to the extent such
costs, fees or expenses are expressly included in Excluded Practice Expenses or

hereunder as is necessary or appropriate for the efficient operation of the
Practice, including, without limitation, performance of some of the business
office functions at locations other than the Practice. Except to the extent
necessary to comply with applicable laws, regulations or professional ethical

perform its services hereunder. Administrator shall cause its employees, to
comply with all applicable federal, state and local laws, rules and regulations
in Administrator's provision of services hereunder.

procedures Administrator, Parent or their Affiliates shall utilize to restore
the level of service contemplated by this Agreement. In the event Administrator
fails to restore the level of service contemplated by this Agreement in
accordance with such plan submitted or in any event within ninety (90) days, the
Group shall be entitled to reimbursement by Administrator for the reasonable
costs and expenses of obtaining such service on a temporary basis until such
time Administrator demonstrates its ability to perform such service at the level
contemplated by this Agreement. Nothing contained in this subsection (b)(i)
shall be construed to limit the Group's ability to provide notice of a Material
Administrator Default pursuant to Section 10.3(b) of this Agreement.

                  (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service
is construed or deemed to constitute the practice of medicine, Administrator
shall deliver to the Group notice of such an event. The Group shall be entitled
to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

its exclusive manager and administrator of non-medical business services
relating to the operation of the Practice, subject to matters reserved for the
Group or referred to the Joint Planning Board as herein contemplated, and
Administrator shall have all necessary authority and hereby agrees to perform
such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

         (b)  Billing and Collection.

                  (i) Administrator shall, in the name of and on behalf of the
Group, bill patients, insurance companies, Managed Care Payors, and other

the Practice at the Premises or any Practice Site(s) (including all fees
generated by both the Technical Operations and the Professional Operations), for
services performed outside the Practice for its hospitalized patients, and for
all other professional and Practice services. The Group hereby appoints
Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:

                                       10
<PAGE>   16

                         (A) to bill patients, insurance companies, Managed Care
Payors, and other third-party payors in the Group's name and on its behalf;

                         (B) to collect accounts receivable resulting from such
billing not otherwise purchased by Administrator (as provided for in Section
3.2(e) hereof) in the Group's name and on its behalf;

                         (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                         (D) to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                         (E) to take possession of and endorse in the name of
the Group and deposit into the Deposit Account (and/or in the name of an
individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                         (F) upon the prior consent of the Group, which consent
shall not be unreasonably withheld or delayed, to initiate the institution of
legal proceedings in the name of the Group or a Physician Employee to collect
any accounts and monies owed to the Group or the Physician Employee, to enforce
the rights of the Group or the Physician Employee, as the case may be, as
creditor under any contract or in connection with the rendering of any service,
and to contest adjustments and denials by governmental agencies (or their fiscal
intermediaries) as third-party payors.

                  (ii) The Group hereby appoints Administrator as its true and
lawful attorney-in-fact to deposit into the Deposit Account all Professional
Revenues and Technical Revenues collected by Administrator as provided for in
this Section 3.2(b). The Group covenants, and shall cause all Physician
Employees and Physician Extender Employees to covenant, to forward any payments
received with respect to any Professional Revenues or Technical Revenues
generated for services provided by the Group or any of its Physician Employees
and Physician Extender Employees to Administrator for deposit. Administrator
shall have the right to withdraw funds from the Deposit Account and all owners
of the Deposit Account shall execute a revocable standing transfer order (the
"Transfer Order") under which the bank maintaining the Deposit Account shall
periodically transfer the entire balance of the Deposit Account to a separate
bank account owned solely by Administrator (the "Administrator Account"). The
Group and Administrator hereby agree to execute from time to time such documents
and instructions as shall be required by the bank maintaining the Deposit
Account and mutually agreed upon to effectuate the foregoing provisions and to
extend or amend such documents and instructions. Any action by the Group that
materially interferes with the operation of this Section, including but not
limited to, any failure to deposit or to have Administrator deposit any


                                       11
<PAGE>   17

Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit Account not authorized by the express
terms of this Agreement or any other written agreement executed by each of the
parties, or any revocation of or attempt to revoke the Transfer Order (otherwise
than upon expiration or termination of this Agreement), will constitute a breach
of this Agreement and will entitle Administrator, in addition to any other
remedies it may have at law or in equity, to seek a court ordered assignment of
the rights provided to Administrator pursuant to subparagraph (i) above.

                  (iii) All monies shall be accounted for by Administrator as
being distinctly attributable to the Group. The Group may perform the functions
or exercise the rights set forth in this Section 3.2(b) only with the prior
written consent of Administrator. The Group shall execute such documents in form
and substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c) Accounting. Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of
the Practice, and Administrator shall perform all bookkeeping and accounting
services necessary or appropriate for the efficient operation of the Practice,
including the maintenance, custody and supervision of business records, ledgers
and reports; the establishment, administration and implementation of accounting
procedures, controls and systems; and implementation and management of
computer-based management information systems. The Group and its authorized
representatives shall have the right to review all financial books and records
maintained by Administrator relating to the operation of the Practice and to the
cash management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the parties have
agreed herein. The purchase price shall be an amount equal to the aggregate face
amount of the accounts receivable being sold less contractual adjustments and


                                       12
<PAGE>   18

estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

         (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication
services and medical transcribing services; provided, however, that the Group
may elect to prepare its own Tax Returns, in which case, the cost of preparing
such Tax Returns in excess of $2,500 per annum shall be included in Excluded
Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group
containing a balance sheet, income statement and monthly operational reports
which detail payments, charges and accounts receivable statistics, monthly
reconciliation reports on cash management and any other financial reports
reasonably requested by a member of the Joint Planning Board designated by the
Group, which shall be delivered to the Group as soon as practicable, but no
later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

         (g)  Records and Files.

                  (i) Administrator's Business and Financial Records. At all
times during and after the term of this Agreement, including any extensions or
renewals hereof, all business records, including but not limited to, business
agreements, books of account, personnel records, general administrative records
and all information generated under or contained in the management information
system pertaining to Administrator's obligations hereunder, and other business
information of Administrator of any kind or nature, except for patient medical
records and the Group's Records (as defined in subparagraph (ii) below), shall
be and remain the sole property of Administrator; provided that during and after
termination of this Agreement, the Group shall be entitled to reasonable access
to such records and information, including the right to obtain copies thereof in
any media reasonably requested by the Group, for any purpose related to patient
care or the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years. Administrator hereby agrees
to preserve the confidentiality of such patient medical records and to use the
information in such records only for the limited purposes necessary to perform
management services and, within the limits of its responsibilities hereunder, to
ensure that provision is made for appropriate care for patients of the Practice.

<PAGE>   19

                  (ii) The Practice's Business and Financial Records. At all
times during and after the term of this Agreement, the business agreements,
financial, operational, corporate and personnel records and information relating
exclusively to the business and activities of the Group and patient medical
records and charts (hereinafter referred to as the "Group's Records") shall be
and remain the sole property of the Group.

                  (iii) Access to Records. At all times during and after the
term of this Agreement, each party and its authorized agents shall be entitled,
upon request and with reasonable advance notice, to obtain access (within not
more than 30 days following receipt of such notice by the other party or
parties) to all records of the other party directly related to the performance
of such party's obligations pursuant to this Agreement; provided, however, that
such right shall not allow for access to patient, medical and other records that
must be kept confidential as required by law. Either party, at its expense,
shall have the right to make copies in any media of any records to which it has
access pursuant to this subparagraph (iii).

                  (iv) Compliance with Law. The management of all files and
records by Administrator and the Group shall comply with all applicable federal,
state and local statutes and regulations.

         (h) Collections. Subject to the consent requirement contained in
Section 3.2(b)(i)(F), Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees and
pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

         Section 3.3  Facilities.

Premises that are described in Exhibit 3.3(a) attached hereto and such other
improvements made by Administrator or Parent for the use of the Group hereunder.

property necessary or appropriate for the efficient operation of the Practice
acquired by Administrator or Parent (subject to review and approval of the Joint

repairs thereto.

                                       14
<PAGE>   20

         (c) Expenses. All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the
Premises and the Personal Property, including, without limitation, all
reasonably necessary costs of repairs, maintenance and improvements, utility
expenses (i.e., telephone, electric, gas and water), janitorial services, refuse
disposal, real or personal property lease cost payments and expenses, interest,
refinancing expenses, depreciation, loss on disposition of assets, taxes and
casualty, liability and other insurance, shall be included in Practice Expenses.
To the extent the Premises or Personal Property are used in connection with the
Professional Operations, the costs and expenses associated with such usage shall
be allocated between Professional Expenses and Technical Expenses as approved by
the Joint Planning Board.

         (d) Disposition. Subject to provisions contained in existing agreements
to which Administrator or Parent is or becomes a party and, where necessary and
appropriate for the efficient operation of the Practice, nothing herein shall be
construed as precluding Administrator or Parent from selling, leasing or
otherwise disposing of all or any part of the Premises, Personal Property, real
property, improvements, trade names, trademarks and other intangible property;
provided, however, any such sale, lease or disposition shall be subject to the
prior review and approval of the Joint Planning Board and shall not eliminate or
diminish Administrator's obligations hereunder.

         (e) No Warranties or Representations. The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

         Section 3.4  Acquisition and Assistance.

         (a) Employment of Physicians. Subject to consultation with the Joint
Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice. Subject to
consultation with the Joint Planning Board, in the event that a decision is made
by the Group to pursue the employment of selected physicians, if requested by
the Group, Administrator will provide recruiting, consulting, negotiating and
other advisory services in connection with such transaction. Notwithstanding the
preceding, as set forth in and subject to the provisions of Section 4.1 hereof,
the Group shall have complete control of and responsibility for the hiring of
all Physician Employees and Physician Extender Employees.

         (b) Acquisitions. In the event that the Group contemplates acquiring or
affiliating with a physician group, practice or other entity, and such
acquisition or affiliation involves the use or expenditure of Administrator's
and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a
result of such an acquisition or affiliation including, without limitation,
capital and personnel (collectively, the "Resources"), then the Group shall
first consult with the Joint Planning Board and Administrator, and any decision
to make such affiliation or acquisition shall

                                       15
<PAGE>   21

be subject to prior approval of Administrator, which decision of the
Administrator shall be provided to the Group in a reasonable and timely manner
following satisfactory review of the physician group, practice or other entity
to be acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto. If such contemplated acquisition or affiliation does not
involve the use or expenditure of any of Administrator's and/or Parent's
Resources, then such decision shall be in the sole discretion of the Group.
Notwithstanding any provision contained herein to the contrary, any person or
entity with which the Group affiliates or acquires shall be subject to the terms
and conditions of this Agreement. If a decision is made to proceed with any
affiliation or acquisition of a physician group or practice, the Group may seek
from Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

         Section 3.5  Financial Planning and Budgeting.

         (a) Budgeting. Administrator shall collaborate with the Group and the
Joint Planning Board in the preparation of all annual capital and operating
budgets. These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors. For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board. The
projected annual operating budget for each subsequent year shall be subject to
the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice. For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

         (b) Capital Expenditures. Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

                  (i) Budgeted Expenditures. All budgeted capital expenditures
and improvement projects shall be subject to final review and approval by the
Joint Planning Board prior to the making of any actual expenditure. Such review
and approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.


                                       16
<PAGE>   22

                  (ii) Non-Budgeted Expenditures. Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared by
the Joint Planning Board in consultation with the Group and Administrator. All
requests for non-budgeted capital expenditures and improvements at or for the
benefit of the Practice in excess of either $75,000 individually or an aggregate
amount equivalent to $2,500 multiplied by the number of Full-time Physician
Employees employed at the time the capital budget for such Group for the
applicable year is determined (provided, however, that such aggregate amount
shall not exceed $250,000 for any calendar year) must be approved by the Board
of Directors of Parent or by any committee specifically designated by the Board
of Directors of Parent for such purposes.

         (c) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors"). Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning


                                       17
<PAGE>   23

Board, be the responsibility of the Group. Notwithstanding the preceding
language, if a contract or relationship between any Managed Care Payor and the
Group involves or affects a contract or relationship with any other physician
group or practice serviced or managed by Administrator, Parent or any of their
Affiliates (the "Other Practices") and a consensus among the Group and the Other
Practices cannot be reached regarding the contract or relationship, then the
ultimate decision as to the approval, disapproval, termination or amendment of
such contract or relationship involving the Group, the Other Practices and such
Managed Care Payor shall be determined by the affirmative vote of the Physician
Board Members (as defined below) who hold a majority of the Group Voting Power
(as defined below). For purposes of this Section 3.7, (i) the term "Physician
Board Members" shall mean (a) those members appointed by the Group who serve on
the Joint Planning Board and (b) those persons appointed by the Other Practices
who serve on the Other Practices' joint boards (in a similar capacity to the
Joint Planning Board) as part of their contractual relationship with Parent,
Administrator or any of their Affiliates, and (ii) the term "Group Voting Power"
shall mean the total voting percentage which may be cast by the Physician Board
Members on a collective basis, with the percentage of votes able to be cast by
any Group or Other Practice, as applicable, shall be equal to the quotient
determined by dividing (x) the total estimated annual professional revenues to
be generated by the Group from such Managed Care Contract as determined by
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion, by (y) the total estimated annual professional revenues to be
generated by the Group and all Other Practices from such Managed Care Contract
as determined by the Administrator, Parent or their Affiliates, as appropriate,
in its sole discretion.

         Section 3.8 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.9 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and advertising programs shall be
conducted in compliance with applicable standards of medical ethics, laws and
regulations.

<PAGE>   24

         Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program
shall be included in Administrator Expenses; provided, however, that any
expenses related to such program that are incurred for services provided solely
for the direct benefit of the Practice shall be included in Practice Expenses.

         Section 3.11 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by
the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

         Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.


                                   ARTICLE IV

                            Obligations of the Group

         Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender
Employees, and other employees who may have malpractice exposure or liability,
are insurable and by participating in an ongoing risk management program.


                                       19
<PAGE>   25

         Section 4.2 Professional Services. The Group shall provide professional
services to its patients in compliance at all times with ethical standards,
laws, rules and regulations applicable to the operations of the Practice, the
Physician Employees and Physician Extender Employees. The Group shall ensure
that each Physician Employee and each Physician Extender Employee has all
required licenses, credentials, approvals or other certifications to perform his
or her duties and services for the Practice and, in the event that the Group
becomes aware of any disciplinary actions or medical malpractice actions
initiated against any Physician Employee or Physician Extender Employee, the
Group shall promptly inform Administrator of such action and the underlying
facts and circumstances. If required by applicable law, any state or federal
regulatory agency or any contractual obligations, the Group shall carry out a
program to monitor the quality of medical care practiced at the Practice;
provided, however, that the preceding language shall not limit the Group's
obligation to participate in or comply with any programs established by
Administrator or Parent for purposes of ensuring that the Group complies with
applicable law. The Group shall employ Physician Employees and Physician
Extender Employees as is necessary to provide efficient medical care to patients
of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery

                              Joint Planning Board

         Section 5.1  Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy is counted;
provided, however, that no proxy shall be valid after the expiration of eleven
(11) months from the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2  Duties and Responsibilities of the Joint Planning Board.  
The Joint Planning Board shall advise the Group on the following matters:

the particular project and the Group as a whole.

         (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess
of five percent (5%) to the annual capital or operating budgets.

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

upon the pricing, access to, and quality of such services and shall review and
adopt the fee schedule for all ancillary services.

         (f) Provider and Payor Relationships. Subject to Section 3.7, decisions
regarding the establishment or maintenance of relationships with institutional
health care providers and payors shall be approved by the Group after
consultation with the Joint Planning Board.

         (g) Strategic Planning. The Joint Planning Board shall develop a plan

priority of capital expenditures in accordance with Section 3.5(b) hereof.

Board. The Group agrees that, unless the following are approved in advance by
the Joint Planning Board and such act of the Joint Planning Board includes the

Joint Planning Board. No action of the Joint Planning Board shall be effective
unless authorized by the members holding a majority of the voting power of the
Joint Planning Board present or represented by proxy at the applicable meeting.
In the event that a matter cannot be resolved by the Joint Planning Board due to
a tie vote, and no compromise can be reached, then either (x) the Board of
Directors of Parent or (y) a committee designated by the Board of Directors of
Parent containing at least one (1) physician member will make a final
determination on the matter in dispute provided that both the Group and
Administrator shall have had an opportunity to make a presentation to the Board
of Directors of Parent or a committee thereof, as applicable. A quorum of the
Joint Planning Board shall consist of the members holding a majority of the
voting power of the Joint Planning Board, present in person, by telephone, or by
proxy and the quorum must remain for the duration of the meeting.

         Section 5.4 Joint Planning Board Meetings. Meetings of the Joint
Planning Board may be held by telephone or similar communication equipment so
long as all members participating in a meeting can hear and speak to each other.

may be called by fifty percent (50%) of the votes.

         (c) Notice Requirement. A member calling a special meeting must provide
all other members with ten (10) days' advance written or telephonic notice.
Notice must be given or sent to the member's address or telephone number as

directly to each member or to a person at the member's principal place of
business who would reasonably be expected to communicate that notice promptly to
the member.

                  (i) Written Waiver, Consent or Approval. Notice of a special
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the special meeting. Such waiver,
consent or approval need not specify the purpose of the special meeting. All
such waivers, consents, and approvals shall be filed with the Joint Planning
Board records or made a part of the minutes of the special meetings.

                  (ii) Failure to Object. Notice of special meeting need not be

any Practice Site(s) and (ii) to be bound by non- solicitation, noncompetition
and nondisclosure of confidential/proprietary information and engagement of
Administrator covenants similar to those applicable to the Group as contained in
Section 6.1 hereof. Except as otherwise approved by the Joint Planning Board,
each Group Physician Stockholder or Full-time Physician Employee shall agree
that during the term of his/her employment or contractor agreement with the
Group (w) not to practice radiological medicine other than at the Premises or
such other location or Practice Site(s) as approved by the Joint Planning Board;
(x) to devote substantially all of his or her professional time, effort and
ability to the Practice; (y) to request in writing and receive in writing prior
approval from the Joint Planning Board to engage in any outside medical
activities; and (z) to turn over to the Practice, to be included in Professional
Revenues attributed to the Practice, any income derived by such Group Physician
Stockholder or Full-time Physician Employee from any outside medical activity or
related source from the following medically-related activities: teaching,
consulting,


                                       30

medical research, inventions developed utilizing the Group's or the Practice's
time and material, testimony for litigation, and insurance examinations. The
Group shall not materially amend, alter or otherwise change any term or
provision of any Stockholder Employment Agreement or Physician Employee
Employment Agreement relating to the foregoing covenants in this Section 6.2
without the prior written consent of Administrator; notwithstanding the
foregoing, any such amendment, alteration or change shall not be inconsistent
with the terms or provisions of this Agreement. Following termination of this
Agreement, the Group shall not amend, alter or otherwise change any term or
provision of the Restrictive Covenants, unless such provisions are no longer in
force and effect pursuant to the terms of the applicable Stockholder Employment
Agreement or Physician Employee Employment Agreement at the time of termination
of this Agreement. In the event the Purchase Assets are acquired by the Group
pursuant to Article X, the obligation of the Group to enforce Restrictive
Covenants shall be limited to enforcement of non-solicitation and nondisclosure
of confidential/proprietary information covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Stockholder Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Stockholder Employment
Agreements and, to the extent permitted under applicable law, the Physician
Employee Employment Agreements, upon the request of Administrator, the Group
shall assign to Administrator such causes of action and/or other rights it has
related to such breach or default and shall cooperate with and provide
reasonable assistance to Administrator with respect thereto; in which case, all
costs and expenses incurred in connection therewith shall be borne by
Administrator and shall be included in Administrator Expenses, and Administrator
shall be entitled to all damages and other amounts recovered thereby. In the
event the Purchase Assets are acquired by the Group pursuant to Article X, the
obligation of the Group to enforce Restrictive Covenants shall be limited to
enforcement of non-solicitation and nondisclosure of confidential/proprietary
information covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period,


                                       31
<PAGE>   37

scope of activity restricted and/or the geographical area applicable to such
provision of the Restrictive Covenants or this Article VI. The invalidity or
non-enforceability of any provision of the Restrictive Covenants or this Article
VI in any respect shall not affect the validity or enforceability of the
remainder of the Restrictive Covenants or this Article VI or of any other
provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Stockholder or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Stockholder or Full-time Physician Employee from the restrictive
covenants contained in Section 6.2, above. In the event the Group elects to
release such Group Physician Stockholder or Full-time Physician Employee, the
Group hereby covenants that it shall obtain a formal agreement between each
Group Physician Stockholder or Full-time Physician Employee, as the case may be,
and Administrator which provides that, for a period of two (2) years following
termination of any employment agreement with the Group, such Group Physician
Stockholder or Full-time Physician Employee agrees to (a) engage Administrator
as the sole and exclusive manager and administrator of the non-medical functions
and services of said Group Physician Stockholder's or Full-time Physician
Employee's medical practice and (b) pay to Administrator the identical amount
[NY only] of revenues paid by the Group to the Administrator attributable to
such Group Physician Stockholder or Full-time Physician Employee derived from
such Group Physician Stockholder's or Full-time Physician Employee's performance
of professional medical services within 15 miles of any Practice Site.

         Section 6.6 Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary
information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and

                                       32
<PAGE>   38

work effort required and (y) the Group shall not be required to employ any
Radiologist previously associated with such Professional Service Opportunity.

         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half of the time during which the
Administrator, Parent or their Affiliates must respond to an offer described in
the Administrator's Notice, the Group shall deliver to Administrator a written
notice stating whether or not the Group elects to accept or reject the New
Professional Service Opportunity which election shall be binding on the Group.
If the Group does not elect to exercise the right or fails to provide the notice
to Administrator within the time frame herein provided, Administrator shall be
released from the right of first offer with respect to that particular New
Professional Service Opportunity. Prior to consummating any asset acquisition,
merger or other consolidation of any Radiologist, group of Radiologists, or
professional corporation or association (or other professional entity) whose
owners are Radiologists within any Secondary Service Area, Administrator shall
first consult with the Joint Planning Board.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service Opportunity as contemplated in 
subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

                  "New Professional Service Opportunity" shall mean a
Professional Service Opportunity pursuant to which the Group or any other member
of an APPI Group managed by Parent, Administrator or their Affiliates is not
currently providing professional Radiology services.

                  "Primary Service Area" shall mean that area within a five (5)
mile radius from any imaging center owned, operated or managed by Administrator,
Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.


                                       33
<PAGE>   39

                  "Professional Service Opportunity" shall mean any opportunity
to perform professional Radiology services for any hospital, hospital system or
imaging center under a formal agreement with such entity.

                  "Radiologist" shall mean and include both radiologists and

radiation oncologists.

                  "Radiology" shall mean and include diagnostic imaging,
interventional radiology and radiation oncology services.

                  "Secondary Service Area" shall mean (i) during the 12-month
period following the Acquisition Effective Date, that area which extends ten
(10) miles beyond the boundary of any Primary Service Area and (ii) during the
remaining term of this Agreement, that area which extends five (5) miles beyond
the boundary of any Primary Service Area.

         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.


                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on


                                       34
<PAGE>   40

Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates based
upon available information for such month, and adjustments to the estimated
payments shall be made to reconcile final amounts due under Section 7.1 on the
next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee


                                       35
<PAGE>   41

and to other related provisions of this Agreement shall be a joint decision of
the parties, shall be memorialized in a written amendment to this Agreement, and
shall be based upon the methodology used to generally determine Services Fees
hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

               (a) payment of all accrued Practice Expenses for the prior month
                   (subject to the proviso in the preceding sentence;

               (b) payment of the accrued Service Fee for the prior month;

               (c) payment of outstanding balance of all amounts advanced to the
                   Group, through the end of the prior month, and applicable
                   interest thereon (as contemplated in Section 7.3); and

               (d) payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).


                                  ARTICLE VIII

                                     Records

         Section 8.1 Records. All records relating in any way to the operation
of the Practice (other than Group Records) shall, subject to the obligations of
the Practice to maintain patient medical records pursuant to Section 3.2(g), at
all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter, the
Group or its agents shall have reasonable access during normal business hours to
the Group's and Administrator's personnel and financial records relating to the
Practice, including, but not limited to, records of collections, expenses and
disbursements as kept by Administrator in


                                       36
<PAGE>   42

performing Administrator's obligations under this Agreement, and the Group may
copy any or all such records.


                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1 Insurance to be Maintained by the Group.

         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.

                                       37
<PAGE>   43

         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.

         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5 Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its shareholders, employees
and/or subcontractors (other than Administrator, Parent, Affiliates or their
employees, officers, directors, agents, attorneys and consultants) during the
term of this Agreement. Provided, however, that in the event an indemnification
obligation under the preceding sentence arises as of the result of any act or
omission of a person who is an officer, shareholder or other equity holder,
director, employee, agent, attorney or consultant of Administrator, Parent or
any of their Affiliates (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
the Group's indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or
incurred, that are caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts or omissions by Administrator, Parent or Affiliates and/or any of
their respective shareholders, employees and/or subcontractors (other than the
Group or its employees) during the term of this Agreement. Provided, however
that

                                       38
<PAGE>   44

in the event an indemnification obligation under the preceding sentence arises
as a result of any act or omission of a person who is an officer, shareholder or
other equity holder, director, employee, agent, attorney or consultant of the
Group (other than in connection with the activities of the Joint Planning
Board), such person shall not be entitled to indemnification in connection
therewith and any other adjustment as is equitable shall be made to
Administrator's or Parent's indemnification obligation arising thereby.


                                    ARTICLE X

                              Term and Termination

         Section 10.1 Term of Agreement. This Agreement shall commence on the
date hereof and shall expire on the 40th anniversary hereof unless earlier
terminated pursuant to the terms of either Section 10.3 or Section 10.4 or
automatically extended pursuant to the terms of Section 10.2.

         Section 10.2 Extended Term. Unless earlier terminated as provided for
in either Section 10.3 or Section 10.4, the term of this Agreement shall be
automatically extended for additional terms of five (5) years each, unless
either party delivers to the other party, not less than twelve (12) months nor
earlier than fifteen (15) months prior to the expiration of the preceding term,
written notice of such party's intention not to extend the term of this
Agreement.

         Section 10.3 Termination by the Group. The Group may, in its sole
discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not

                                       39
<PAGE>   45

the obligation, to cure any Material Adminstrator Default. Notwithstanding
anything to the contrary in this Agreement, following receipt by Administrator
of the notice of a Material Administrator Default and until such Material
Administrator Default shall be cured, the Group may take such action as may be
reasonably required to cover such Material Administrator Default so as to
maintain for the Group the same level of service as before the Material
Administrator Default, without prejudicing in any way the Group's other rights
and remedies, and may offset all of its costs from the amounts which may
otherwise be due to Administrator under this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that

                                       40

individual from participating in or from receiving reimbursement under any
program funded by the federal government or by any state government,
notwithstanding any available post-sanction remedies, or (4) is otherwise
disciplined by any licensing, regulatory or professional entity or institution,
the result of any of which event does or is reasonably expected to materially
adversely affect the Practice, the result of any of which event described in
subparagraphs (1) through (4) above, in the absence of termination of a
Physician Employee or a Physician Extender Employee or other action of the Group
to monitor and cure such act or conduct by such employee, does or reasonably
would be expected to materially and adversely affect the Practice or the Group.
Notwithstanding anything to the contrary in this Agreement, following receipt by
the Group of the notice of a Material Group Default, and until such Material
Group Default shall be cured, the Administrator may take such action as may be
reasonably required to cover such Material Group Default so as to maintain for
the Administrator the same level of service at the Premises as before the
Material Group Default, without prejudicing in any way Administrator other
rights and remedies, and may offset all of its costs of cover from amounts which
may otherwise due to the Group under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Stockholders and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
(with the exception of Hector Correa, Nancy Sussman, M.D., or Herbert Z. Geller)
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee [or Physician Extender Employee] that intends to
retire prior to expiration of such five-year period, then such Physician
Employee or Physician Extender Employee shall not be counted for purposes of
determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         (b) Upon the expiration of this Agreement pursuant to Sections 10.1 or
10.2.

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator and/or Parent, the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or their
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's or their Affiliates' accounting and financial records (the "Purchase
Assets"), including, but not limited to, without duplication, (i) all equipment,
furniture, fixtures, furnishings, inventory, supplies, improvements, additions
and leasehold improvements utilized by the Practice, (ii) any real estate owned
by Administrator, Parent or Affiliates that is occupied by or used primarily for
the benefit of the Practice, (iii) all unamortized intangible assets (including,
without limitation, goodwill) set forth on the financial statements of
Administrator, Parent or their Affiliates used solely in connection with the
Practice or otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and their Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c) Purchase Price. The Purchase Price shall be the lesser of (i) Fair
Market Value of the Purchase Assets subject to the assumption of the Practice
Related Liabilities or (ii) the value of the Actual Consideration (defined
below)(alternatively, the "Purchase Price"); provided, however, the Purchase
Price shall not be less than the net book value of the Purchase Assets at the
Termination Date. The Purchase Price shall be paid pursuant to Section 10.7. For
purposes of this subparagraph (c), the term "Actual Consideration" shall mean
(i) cash consideration paid to the Group pursuant to the Acquisition Agreement
and (2) an amount equal to the number of shares of Parent Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, reorganizations,
or any similar transaction whereby the Parent Common Stock is increased or
decreased or exchanged for a different number or kind of securities) issued
pursuant to the Acquisition Agreement multiplied by the fair market value of
Parent Common Stock immediately prior to the time that a Termination Notice is
provided pursuant to Section 10.7. The Purchase Price shall be appropriately
adjusted to offset and account for any monetary obligations of the Group or
Administrator owing to the other as provided herein.

         (d)      Exercise of Option.

                  (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                  (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

         (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at the Purchase Closing, Administrator and/or its Affiliates, as the case
may be, shall transfer and assign the Purchase Assets to the Group, and in
consideration therefor, the Group shall (a) pay to Administrator, Parent and/or
their Affiliates an amount in cash or, at the option of the Group (subject to
the conditions set forth below), Parent Common Stock (valued pursuant to Section
10.6(c) hereof), or some combination of cash and Parent Common Stock equal to
the Purchase Price and (b) assume the Practice Related Liabilities. The
structure of the transaction set forth in this Section 10.7 shall, if possible,
be structured as a tax-free transaction under applicable law. Each party shall
execute such documents or instruments as are reasonably necessary, in the
opinion of each party and its counsel, to effect the foregoing transaction. The
Group shall, and shall use its best efforts to cause each shareholder of the
Group to, execute such documents or instruments as may be necessary to cause the
Group to assume the Practice Related Liabilities and to release Administrator,
Parent and/or their Affiliates, as the case may be, from any liability or
obligation with respect thereto. In the event the Group desires to pay all or a
portion of the Purchase Price in shares of Parent Common Stock, such transaction
shall be subject to the satisfaction of each of the following conditions:


                                       43
<PAGE>   49

         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims, proxies, options, stockholders' agreements
and encumbrances (not including any applicable securities restrictions and
lock-up arrangements with the Parent or any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain financing for such acquisition but is unable to
obtain such financing and (iii) there is either a Material Administrator Default
pursuant to Section 10.3(a) or (c) or a Material Group Default pursuant to
Section 10.4(b) triggering a sale of the Purchase Assets, the Group shall be
entitled to obtain financing from Administrator, Parent and/or their Affiliates
but only for the difference between the Fair Market Value of the Purchase Assets
and the net book value of the Purchase Assets. The terms of such financing shall
be for a five (5) year period at an interest rate equal to the prime rate (as
published in the Wall Street Journal) plus four percent (4%) or such lesser rate
as is required to be in conformance with all applicable state and federal law.
In the event the Group is entitled to obtain financing from Administrator,
Parent and/or their Affiliates, the Group shall execute and deliver to
Administrator, Parent and/or their Affiliates all such documentation necessary
and appropriate to effectuate the financing transaction including, without
limitation, a secured promissory note, security agreement and financing
statements and such documentation shall contain such representations, warranties
and conditions customary to a secured transaction of this size.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator, Parent and/or their Affiliates to the
Group or the Group to the Administrator, Parent and/or their Affiliates


                                       44
<PAGE>   50

(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

         (a) Administrator, Parent and/or their Affiliates shall use their best
efforts to cooperate with the Group for the appropriate transfer of management
services.

         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.

         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.


                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

         Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means


                                       45
<PAGE>   51

set forth in Section 11.1 and prior to commencing an arbitration procedure
pursuant to this Article XI, the parties shall meet to discuss and consider
other alternative dispute resolution procedures other than arbitration,
provided, however that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including rules of
evidence and procedure. If at any time prior to the rendering of the decision by
the arbitrator (or pursuant to such other alternative dispute resolution
procedure) as contemplated in this Article XI to the extent a party makes a
written offer to the other party proposing a settlement of the matter(s) at
issue and such offer is rejected, then the party rejecting such offer shall be
obligated to pay the costs and expenses (excluding the amount of the award
granted under the decision) of the party that offered the settlement from the
date such offer was received by such other party if the decision is for a dollar
amount that is less than the amount of such offer to settle. Notwithstanding the
foregoing, the terms and provisions of this Article XI shall not preclude any
party hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

         Section 11.3 Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among Administrator and the Group arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within 30 days of notice
by a party to the other of its desire to seek arbitration under this Article XI
one arbitrator mutually acceptable to Administrator and the Group to hear and
decide all such claims under this Article XI. If such matter or action involves
health-care issues, then the arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators proposed shall be impartial
and independent of all parties. If the parties cannot agree on the selection of
an arbitrator within said 30-day period, then any party may in writing request
the judge of the United States District Court for the Southern District of New
York (White Plains) senior in term of service to appoint the arbitrator and,
subject to this Article XI, such arbitrator shall hear all arbitration matters
arising under this Article XI.

         Section 11.4 Applicable Rules.

         (a) Each arbitration hearing shall be held at a place in Weschester or
Rockland Counties, New York, acceptable to the arbitrator. The arbitration shall
be conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof. The decision of the arbitrator shall be reduced to writing and shall be
binding on the parties and such decision shall contain a concise statement of
the reasons in support of such decision. Judgment upon the award(s) rendered by
the arbitrator may be entered and execution had in any court of competent
jurisdiction or application may be made to such court for a judicial acceptance
of the award and an order of enforcement. The charges and expenses of the
arbitrator shall be shared equally by the parties to the hearing.

                                       46
<PAGE>   52

         (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI. In
fulfilling his duties with respect to determining the amount of any loss, the
arbitrator may consider such matters as, in the opinion of the arbitrator, are
necessary or helpful to make a proper valuation. The arbitrator may consult with
and engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

         (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.

         (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e) All privileges under New York and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying New York law.


                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment.

         (a) Administrator shall have the right to assign its rights hereunder
to Parent or any direct or indirect wholly-owned subsidiary of Administrator or
Parent (that remains a wholly-owned subsidiary of Administrator or Parent) or to
a financial institution as collateral security for the indebtedness of Parent,
Administrator or their Affiliates without the consent of the Group. No
assignment under subsection (a) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         (b) Administrator, Parent and their Affiliates shall provide notice to
the Group of Administrator's intent (i) to assign this Agreement (other than as
permitted in Section 12.1(a) herein), (ii) sell all or substantially all of the
assets of Administrator or (iii) effectuate a consolidation, merger or sale of a
majority of the capital stock of Administrator as soon as practicable following
a decision by the Parent's and Administrator's respective boards of directors to
seek such assignment or sale. The assignment of this Agreement (other than as
permitted in Section 12.1(a)), the sale of all or substantially all of the
assets of Administrator by Parent or a consolidation, merger or sale of a
majority of the capital stock of Administrator

                                       47
<PAGE>   53

shall not be permitted unless Administrator shall give written notice to the
Group stating the party who made the offer and specifying the purchase price
offered (the "Notice"). The Group shall have the option to repurchase the
Purchase Assets on the same terms and conditions set forth in the Notice. In the
event the Group fails to provide written notice to Administrator of its intent
to exercise its option to repurchase the Purchase Assets pursuant to this
Section 12.1 within the earlier of (i) thirty (30) days or (ii) one-half of the
time during which Administrator, Parent or their Affiliates must respond to an
offer following the Group's receipt of the Notice, the option contained in this
Section 12.1 shall be deemed null and void and of no further force and effect,
and Administrator shall be free to assign the Agreement, sell all or
substantially all of the assets of Administrator or sell or transfer all of the
capital stock Administrator without the consent of the Group. No assignment
under this subsection (b) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

         Section 12.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 12.4 Additional Documents. Each of the parties hereto agrees to
execute any document or documents that may be reasonably requested from time to
time by the other party to implement or complete such party's obligations
pursuant to this Agreement.

         Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,
costs and expenses including, but not limited to, attorney's fees, costs and
expenses for trial, appellate proceedings and negotiations, in addition to any
other relief granted.

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group
and Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this
Agreement should be construed or deemed, by any governmental authority, agency
or court to constitute the practice of medicine, the performance of said act or
service by Administrator shall be deemed waived and forever unenforceable and
the provisions of this Section 12.6 shall be applicable. Neither party shall
claim or assert illegality as a defense to the enforcement of this Agreement or
any provision

                                       48
<PAGE>   54

hereof; instead, any such purported illegality shall be resolved pursuant to the
terms of this Section 12.6 and Section 12.9.

         Section 12.7 Parties In Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto. Except
as provided in Section 6.1(g), neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party hereto
or thereto any rights or remedies hereunder or thereunder.

         Section 12.8 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

         Section 12.9 Severability. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 12.10 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULE GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF NEW YORK.

         Section 12.11 No Waiver; Remedies Cumulative. No party hereto shall by

the level of service contemplated by this Agreement. In the event Administrator
fails to restore the level of service contemplated by this Agreement in
accordance with such plan submitted or in any event within ninety (90) days, the
Group shall be entitled to reimbursement by Administrator for the reasonable
costs and expenses of obtaining such service on a temporary basis until such
time Administrator demonstrates its ability to perform such service at the level
contemplated by this Agreement. Nothing contained in this subsection (b)(i)
shall be construed to limit the Group's ability to provide notice of a Material
Administrator Default pursuant to Section 10.3(b) of this Agreement.

                  (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service
is construed or deemed to constitute the practice of medicine, Administrator
shall deliver to the Group notice of such an event. The Group shall be entitled
to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

         Section 3.2 General Administrative Services.

         (a) Exclusive Management Services; Scope of Services. Except as
provided in Exhibit 3.2(a), the Group hereby engages Administrator to serve as
its exclusive manager and administrator of non-medical business services
relating to the operation of the Practice, subject to matters reserved for the
Group or referred to the Joint Planning Board as herein contemplated, and
Administrator shall have all necessary authority and hereby agrees to perform
such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

         (b) Billing and Collection.

                  (i) Administrator shall, in the name of and on behalf of the
Group, bill patients, insurance companies, Managed Care Payors, and other
third-party payors and collect all fees for services rendered in connection with
the Practice at the Premises or any Practice Site(s) (including all fees
generated by both the Technical Operations and the Professional Operations), for
services performed outside the Practice for its hospitalized patients, and for
all other professional and Practice services. The Group hereby appoints
Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:


                                       10
<PAGE>   16
                           (A) to bill patients, insurance companies, Managed
Care Payors, and other third-party payors in the Group's name and on its behalf;

                           (B) to collect accounts receivable resulting from
such billing not otherwise purchased by Administrator (as provided for in
Section 3.2(e) hereof) in the Group's name and on its behalf;

                           (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                           (D) to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                           (E) to take possession of and endorse in the name of
the Group and deposit into the Deposit Account (and/or in the name of an
individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                           (F) upon the prior consent of the Group, which
consent shall not be unreasonably withheld or delayed, to initiate the
institution of legal proceedings in the name of the Group or a Physician
Employee to collect any accounts and monies owed to the Group or the Physician
Employee, to enforce the rights of the Group or the Physician Employee, as the
case may be, as creditor under any contract or in connection with the rendering
of any service, and to contest adjustments and denials by governmental agencies
(or their fiscal intermediaries) as third-party payors.

                  (ii) The Group hereby appoints Administrator as its true and
lawful attorney-in-fact to deposit into the Deposit Account all Professional
Revenues and Technical Revenues collected by Administrator as provided for in
this Section 3.2(b). The Group covenants, and shall cause all Physician
Employees and Physician Extender Employees to covenant, to forward any payments
received with respect to any Professional Revenues or Technical Revenues
generated for services provided by the Group or any of its Physician Employees
and Physician Extender Employees to Administrator for deposit. Administrator
shall have the right to withdraw funds from the Deposit Account and all owners
of the Deposit Account shall execute a revocable standing transfer order (the
"Transfer Order") under which the bank maintaining the Deposit Account shall
periodically transfer the entire balance of the Deposit Account to a separate
bank account owned solely by Administrator (the "Administrator Account"). The
Group and Administrator hereby agree to execute from time to time such documents
and instructions as shall be required by the bank maintaining the Deposit
Account and mutually agreed upon to effectuate the foregoing provisions and to
extend or amend such documents and instructions. Any action by the Group that
materially interferes with the operation of this Section, including but not
limited to, any failure to deposit or to have Administrator deposit any


                                       11
<PAGE>   17
Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit Account not authorized by the express
terms of this Agreement or any other written agreement executed by each of the
parties, or any revocation of or attempt to revoke the Transfer Order (otherwise
than upon expiration or termination of this Agreement), will constitute a breach
of this Agreement and will entitle Administrator, in addition to any other
remedies it may have at law or in equity, to seek a court ordered assignment of
the rights provided to Administrator pursuant to subparagraph (i) above.

                  (iii) All monies shall be accounted for by Administrator as
being distinctly attributable to the Group. The Group may perform the functions
or exercise the rights set forth in this Section 3.2(b) only with the prior
written consent of Administrator. The Group shall execute such documents in form
and substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c) Accounting. Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of
the Practice, and Administrator shall perform all bookkeeping and accounting
services necessary or appropriate for the efficient operation of the Practice,
including the maintenance, custody and supervision of business records, ledgers
and reports; the establishment, administration and implementation of accounting
procedures, controls and systems; and implementation and management of
computer-based management information systems. The Group and its authorized
representatives shall have the right to review all financial books and records
maintained by Administrator relating to the operation of the Practice and to the
cash management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the parties have
agreed herein. The purchase price shall be an amount equal to the aggregate face
amount of the accounts receivable being sold less contractual adjustments and


                                       12
<PAGE>   18
estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

         (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication
services and medical transcribing services; provided, however, that the Group
may elect to prepare its own Tax Returns, in which case, the cost of preparing
such Tax Returns in excess of $2,500 per annum shall be included in Excluded
Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group
containing a balance sheet, income statement and monthly operational reports
which detail payments, charges and accounts receivable statistics, monthly
reconciliation reports on cash management and any other financial reports
reasonably requested by a member of the Joint Planning Board designated by the
Group, which shall be delivered to the Group as soon as practicable, but no
later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

         (g) Records and Files.

                  (i) Administrator's Business and Financial Records. At all
times during and after the term of this Agreement, including any extensions or
renewals hereof, all business records, including but not limited to, business
agreements, books of account, personnel records, general administrative records
and all information generated under or contained in the management information
system pertaining to Administrator's obligations hereunder, and other business
information of Administrator of any kind or nature, except for patient medical
records and the Group's Records (as defined in subparagraph (ii) below), shall
be and remain the sole property of Administrator; provided that during and after
termination of this Agreement, the Group shall be entitled to reasonable access
to such records and information, including the right to obtain copies thereof in
any media reasonably requested by the Group, for any purpose related to patient
care or the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years. Administrator hereby agrees
to preserve the confidentiality of such patient medical records and to use the
information in such records only for the limited purposes necessary to perform
management services and, within the limits of its responsibilities hereunder, to
ensure that provision is made for appropriate care for patients of the Practice.


                                       13
<PAGE>   19
                  (ii) The Practice's Business and Financial Records. At all
times during and after the term of this Agreement, the business agreements,
financial, operational, corporate and personnel records and information relating
exclusively to the business and activities of the Group and patient medical
records and charts (hereinafter referred to as the "Group's Records") shall be
and remain the sole property of the Group.

                  (iii) Access to Records. At all times during and after the
term of this Agreement, each party and its authorized agents shall be entitled,
upon request and with reasonable advance notice, to obtain access (within not
more than 30 days following receipt of such notice by the other party or
parties) to all records of the other party directly related to the performance
of such party's obligations pursuant to this Agreement; provided, however, that
such right shall not allow for access to patient, medical and other records that
must be kept confidential as required by law. Either party, at its expense,
shall have the right to make copies in any media of any records to which it has
access pursuant to this subparagraph (iii).

                  (iv) Compliance with Law. The management of all files and
records by Administrator and the Group shall comply with all applicable federal,
state and local statutes and regulations.

         (h) Collections. Subject to the consent requirement contained in
Section 3.2(b)(i)(F), Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees and
pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

         Section 3.3 Facilities.

Premises that are described in Exhibit 3.3(a) attached hereto and such other
improvements made by Administrator or Parent for the use of the Group hereunder.

property necessary or appropriate for the efficient operation of the Practice
acquired by Administrator or Parent (subject to review and approval of the Joint
Planning Board) for the use of the Group pursuant to the terms hereof
(collectively, the "Personal Property"). Administrator shall maintain the
Personal Property in good condition and make or cause to be made all necessary
repairs thereto.


                                       14
<PAGE>   20
         (c) Expenses. All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the
Premises and the Personal Property, including, without limitation, all
reasonably necessary costs of repairs, maintenance and improvements, utility
expenses (i.e., telephone, electric, gas and water), janitorial services, refuse
disposal, real or personal property lease cost payments and expenses, interest,
refinancing expenses, depreciation, loss on disposition of assets, taxes and
casualty, liability and other insurance, shall be included in Practice Expenses.
To the extent the Premises or Personal Property are used in connection with the
Professional Operations, the costs and expenses associated with such usage shall
be allocated between Professional Expenses and Technical Expenses as approved by
the Joint Planning Board.

         (d) Disposition. Subject to provisions contained in existing agreements
to which Administrator or Parent is or becomes a party and, where necessary and
appropriate for the efficient operation of the Practice, nothing herein shall be
construed as precluding Administrator or Parent from selling, leasing or
otherwise disposing of all or any part of the Premises, Personal Property, real
property, improvements, trade names, trademarks and other intangible property;
provided, however, any such sale, lease or disposition shall be subject to the
prior review and approval of the Joint Planning Board and shall not eliminate or
diminish Administrator's obligations hereunder.

         (e) No Warranties or Representations. The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

         Section 3.4 Acquisition and Assistance.

         (a) Employment of Physicians. Subject to consultation with the Joint
Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice. Subject to
consultation with the Joint Planning Board, in the event that a decision is made
by the Group to pursue the employment of selected physicians, if requested by
the Group, Administrator will provide recruiting, consulting, negotiating and
other advisory services in connection with such transaction. Notwithstanding the
preceding, as set forth in and subject to the provisions of Section 4.1 hereof,
the Group shall have complete control of and responsibility for the hiring of
all Physician Employees and Physician Extender Employees.

         (b) Acquisitions. In the event that the Group contemplates acquiring or
affiliating with a physician group, practice or other entity, and such
acquisition or affiliation involves the use or expenditure of Administrator's
and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a
result of such an acquisition or affiliation including, without limitation,
capital and personnel (collectively, the "Resources"), then the Group shall
first consult with the Joint Planning Board and Administrator, and any decision
to make such affiliation or acquisition shall


                                       15
<PAGE>   21
be subject to prior approval of Administrator, which decision of the
Administrator shall be provided to the Group in a reasonable and timely manner
following satisfactory review of the physician group, practice or other entity
to be acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto. If such contemplated acquisition or affiliation does not
involve the use or expenditure of any of Administrator's and/or Parent's
Resources, then such decision shall be in the sole discretion of the Group.
Notwithstanding any provision contained herein to the contrary, any person or
entity with which the Group affiliates or acquires shall be subject to the terms
and conditions of this Agreement. If a decision is made to proceed with any
affiliation or acquisition of a physician group or practice, the Group may seek
from Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

         Section 3.5 Financial Planning and Budgeting.

         (a) Budgeting. Administrator shall collaborate with the Group and the
Joint Planning Board in the preparation of all annual capital and operating
budgets. These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors. For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board. The
projected annual operating budget for each subsequent year shall be subject to
the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice. For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

         (b) Capital Expenditures. Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

                  (i) Budgeted Expenditures. All budgeted capital expenditures
and improvement projects shall be subject to final review and approval by the
Joint Planning Board prior to the making of any actual expenditure. Such review
and approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.


                                       16
<PAGE>   22
                  (ii) Non-Budgeted Expenditures. Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared by
the Joint Planning Board in consultation with the Group and Administrator. All
requests for non-budgeted capital expenditures and improvements at or for the
benefit of the Practice in excess of either $75,000 individually or an aggregate
amount equivalent to $2,500 multiplied by the number of Full-time Physician
Employees employed at the time the capital budget for such Group for the
applicable year is determined (provided, however, that such aggregate amount
shall not exceed $250,000 for any calendar year) must be approved by the Board
of Directors of Parent or by any committee specifically designated by the Board
of Directors of Parent for such purposes.

         (c) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors"). Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning


                                       17
<PAGE>   23
Board, be the responsibility of the Group. Notwithstanding the preceding
language, if a contract or relationship between any Managed Care Payor and the
Group involves or affects a contract or relationship with any other physician
group or practice serviced or managed by Administrator, Parent or any of their
Affiliates (the "Other Practices") and a consensus among the Group and the Other
Practices cannot be reached regarding the contract or relationship, then the
ultimate decision as to the approval, disapproval, termination or amendment of
such contract or relationship involving the Group, the Other Practices and such
Managed Care Payor shall be determined by the affirmative vote of the Physician
Board Members (as defined below) who hold a majority of the Group Voting Power
(as defined below). For purposes of this Section 3.7, (i) the term "Physician
Board Members" shall mean (a) those members appointed by the Group who serve on
the Joint Planning Board and (b) those persons appointed by the Other Practices
who serve on the Other Practices' joint boards (in a similar capacity to the
Joint Planning Board) as part of their contractual relationship with Parent,
Administrator or any of their Affiliates, and (ii) the term "Group Voting Power"
shall mean the total voting percentage which may be cast by the Physician Board
Members on a collective basis, with the percentage of votes able to be cast by
any Group or Other Practice, as applicable, shall be equal to the quotient
determined by dividing (x) the total estimated annual professional revenues to
be generated by the Group from such Managed Care Contract as determined by
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion, by (y) the total estimated annual professional revenues to be
generated by the Group and all Other Practices from such Managed Care Contract
as determined by the Administrator, Parent or their Affiliates, as appropriate,
in its sole discretion.

         Section 3.8 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.9 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and advertising programs shall be
conducted in compliance with applicable standards of medical ethics, laws and
regulations.

<PAGE>   24
         Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program
shall be included in Administrator Expenses; provided, however, that any
expenses related to such program that are incurred for services provided solely
for the direct benefit of the Practice shall be included in Practice Expenses.

         Section 3.11 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by
the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

         Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.


                                   ARTICLE IV

                            Obligations of the Group

         Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender

         Section 4.2 Professional Services. The Group shall provide professional
services to its patients in compliance at all times with ethical standards,
laws, rules and regulations applicable to the operations of the Practice, the
Physician Employees and Physician Extender Employees. The Group shall ensure
that each Physician Employee and each Physician Extender Employee has all
required licenses, credentials, approvals or other certifications to perform his
or her duties and services for the Practice and, in the event that the Group
becomes aware of any disciplinary actions or medical malpractice actions
initiated against any Physician Employee or Physician Extender Employee, the
Group shall promptly inform Administrator of such action and the underlying
facts and circumstances. If required by applicable law, any state or federal
regulatory agency or any contractual obligations, the Group shall carry out a
program to monitor the quality of medical care practiced at the Practice;
provided, however, that the preceding language shall not limit the Group's
obligation to participate in or comply with any programs established by
Administrator or Parent for purposes of ensuring that the Group complies with
applicable law. The Group shall employ Physician Employees and Physician
Extender Employees as is necessary to provide efficient medical care to patients
of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery
items on prepaid Managed Care Contracts which are authorized and permitted by
such contracts. A copy of such agreements and any amendment thereto shall be
provided to Administrator for review no later than thirty (30) days prior to the
proposed effective date thereof.

         Section 4.4 Group's Internal Matters. The Group shall be responsible
for matters involving its corporate governance, employees and similar internal
matters, including, but not limited to, preparation and contents of such reports
to regulatory authorities governing the Group that the Group is required by law
to provide, distribution of professional fee income among the Group Physician
Stockholders, disposition of the Group's property and stock (subject to any


                                       20

restrictions contained herein), hiring and firing of its employees, licensing
and implementing all compliance plans and procedures as described in Section
4.6. Except for the expenses attributable to the distribution of professional
fee income among the Group Physician Stockholders, which will be included in
Excluded Practice Expenses, the costs incurred in connection with the foregoing
matters shall be Practice Expenses.

         Section 4.5 Name. Administrator agrees that the Group shall be entitled
to use on a non-exclusive and non-transferable basis for the term of this
Agreement the names set forth on Schedule 4.5 as may be necessary or appropriate
in the performance of the Group's services and obligations hereunder.

         Section 4.6 Compliance with Laws. The Group shall, and shall use its
best efforts to cause the Physician Employees, Physician Extender Employees and
other employees of the Group to, comply with all applicable federal, state and
local laws, rules, regulations and restrictions in the conduct of the Practice's
business. Without limiting the generality of the foregoing, the Group shall
comply and shall cause each Physician Employee, Physician Extender Employee and
other employee of the Group to comply, with all laws applicable to the operation
of the Practice in the generation, transportation, treatment, storage, disposal
or other handling of radioactive, medical, biological or hazardous materials or
waste, and the Group shall not, and shall use its best efforts to prohibit any
Physician Employee, Physician Extender Employee and any employee of the Group

                              Joint Planning Board

         Section 5.1 Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy is counted;
provided, however, that no proxy shall be valid after the expiration of eleven
(11) months from the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2 Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

the particular project and the Group as a whole.

         (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess
of five percent (5%) to the annual capital or operating budgets.

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

by the Practice.

         (e) Ancillary Services and Fees. The Joint Planning Board shall approve
Practice-provided non-medical ancillary services (including, without limitation,

upon the pricing, access to, and quality of such services and shall review and
adopt the fee schedule for all ancillary services.

         (f) Provider and Payor Relationships. Subject to Section 3.7, decisions
regarding the establishment or maintenance of relationships with institutional
health care providers and payors shall be approved by the Group after
consultation with the Joint Planning Board.

         (g) Strategic Planning. The Joint Planning Board shall develop a plan

priority of capital expenditures in accordance with Section 3.5(b) hereof.

Board. The Group agrees that, unless the following are approved in advance by
the Joint Planning Board and such act of the Joint Planning Board includes the
approval by both of the members designated by Administrator, it shall take no

this Agreement; (ii) have a material adverse effect on the amount of
Administrator's management fee under Article VII; or (iii) otherwise have a

approved by the members holding at least a majority of the voting power of the
Joint Planning Board. No action of the Joint Planning Board shall be effective
unless authorized by the members holding a majority of the voting power of the
Joint Planning Board present or represented by proxy at the applicable meeting.
In the event that a matter cannot be resolved by the Joint Planning Board due to
a tie vote, and no compromise can be reached, then either (x) the Board of
Directors of Parent or (y) a committee designated by the Board of Directors of
Parent containing at least one (1) physician member will make a final
determination on the matter in dispute provided that both the Group and
Administrator shall have had an opportunity to make a presentation to the Board
of Directors of Parent or a committee thereof, as applicable. A quorum of the
Joint Planning Board shall consist of the members holding a majority of the
voting power of the Joint Planning Board, present in person, by telephone, or by
proxy and the quorum must remain for the duration of the meeting.

         Section 5.4 Joint Planning Board Meetings. Meetings of the Joint
Planning Board may be held by telephone or similar communication equipment so
long as all members participating in a meeting can hear and speak to each other.

(15) business days following each meeting.

         (c) Notice Requirement. A member calling a special meeting must provide
all other members with ten (10) days' advance written or telephonic notice.
Notice must be given or sent to the member's address or telephone number as

directly to each member or to a person at the member's principal place of
business who would reasonably be expected to communicate that notice promptly to
the member.

         (d) Waiver of Notice Requirement.

                  (i) Written Waiver, Consent or Approval. Notice of a special
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the special meeting. Such waiver,
consent or approval need not specify the purpose of the special meeting. All
such waivers, consents, and approvals shall be filed with the Joint Planning
Board records or made a part of the minutes of the special meetings.

                  (ii) Failure to Object. Notice of special meeting need not be
given to any member who attends the special meeting and does not protest before
or at the commencement of the special meeting such lack of notice.

of the Group who will have access to all or any part of the Administrator's
Confidential and Proprietary Information will be required to execute an
agreement upon request, valid under the law of the jurisdiction in which such
agreement is executed, and in a form acceptable to Administrator, Parent and
their Affiliates and its counsel, committing themselves to maintain the
Administrator's Confidential and Proprietary Information in strict confidence
and not to disclose it to any unauthorized person or entity. Upon termination


                                       29
<PAGE>   35
of this Agreement for any reason, the Group and their employees shall cease all
use of any of the Administrator's Confidential and Proprietary Information and
shall execute such documents as may be reasonably necessary to evidence their
abandonment of any claim thereto.

                  (iii) Return of Materials. In the event of any termination of
this Agreement for any reason whatsoever, or at any time upon the request of
Administrator, Parent or their Affiliates, the Group will promptly deliver or
cause to be delivered to Administrator, Parent and their Affiliates all
documents, data and other information in their possession that contains any
Administrator's Confidential and Proprietary Information regarding
Administrator, Parent and their Affiliates. The Group shall not take or retain
any documents or other information, or any reproduction or excerpt thereof,
containing any Administrator's Confidential and Proprietary Information, unless
otherwise authorized in writing by the party possessing such Administrator's
Confidential and Proprietary Information. In the event of termination of this
Agreement, the Group will deliver to Administrator, Parent and their Affiliates
all documents and data pertaining to Administrator's Confidential and
Proprietary Information of the other parties not otherwise purchased as part of
the Purchased Assets.

         (f) Third Party Beneficiaries. The members of the APPI Group not party
to this Agreement are hereby specifically made third party beneficiaries of this
Section 6.1, with the power to enforce the provisions hereof.

         Section 6.2 Restrictive Covenants. The Group shall obtain and enforce
formal agreements with each Physician Employee who is either (i) a Group
Physician Stockholder or (ii), to the extent permitted under applicable law, a
Full-time Physician Employee which each contain certain restrictive covenants
thereof pertaining to covenants not to compete and/or solicit with and not to
divulge the Confidential and Proprietary Information of any member of the APPI
Group or the Practice (the "Restrictive Covenants"). Except as otherwise
approved by the Joint Planning Board, each Group Physician Stockholder or
Full-time Physician Employee shall agree, during the term of his/her employment
or contractor agreement with the Practice and for a period of twenty-four (24)
months after any termination of such agreement: (i) not to establish, operate or
provide professional radiology services at any office, practice, hospital or
health care facility providing services substantially similar to those provided
by the Practice pursuant to this Agreement within 15 miles of any location of
any Practice Site(s) and (ii) to be bound by non-solicitation, noncompetition
and nondisclosure of confidential/proprietary information and engagement of
Administrator covenants similar to those applicable to the Group as contained in
Section 6.1 hereof. Except as otherwise approved by the Joint Planning Board,
each Group Physician Stockholder or Full-time Physician Employee shall agree
that during the term of his/her employment or contractor agreement with the
Group (w) not to practice radiological medicine other than at the Premises or
such other location or Practice Site(s) as approved by the Joint Planning Board;
(x) to devote substantially all of his or her professional time, effort and
ability to the Practice; (y) to request in writing and receive in writing prior
approval from the Joint Planning Board to engage in any outside medical
activities; and (z) to turn over to the Practice, to be included in Professional
Revenues attributed to the Practice, any income derived by such Group Physician
Stockholder or Full-time Physician Employee from any outside medical activity or
related source from the following medically-related activities: teaching,
consulting,


                                       30
<PAGE>   36
medical research, inventions developed utilizing the Group's or the Practice's
time and material, testimony for litigation, and insurance examinations. The
Group shall not materially amend, alter or otherwise change any term or
provision of any Stockholder Employment Agreement or Physician Employee
Employment Agreement relating to the foregoing covenants in this Section 6.2
without the prior written consent of Administrator; notwithstanding the
foregoing, any such amendment, alteration or change shall not be inconsistent
with the terms or provisions of this Agreement. Following termination of this
Agreement, the Group shall not amend, alter or otherwise change any term or
provision of the Restrictive Covenants, unless such provisions are no longer in
force and effect pursuant to the terms of the applicable Stockholder Employment
Agreement or Physician Employee Employment Agreement at the time of termination
of this Agreement. In the event the Purchase Assets are acquired by the Group
pursuant to Article X, the obligation of the Group to enforce Restrictive
Covenants shall be limited to enforcement of non-solicitation and nondisclosure
of confidential/proprietary information covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Stockholder Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Stockholder Employment
Agreements and, to the extent permitted under applicable law, the Physician
Employee Employment Agreements, upon the request of Administrator, the Group
shall assign to Administrator such causes of action and/or other rights it has
related to such breach or default and shall cooperate with and provide
reasonable assistance to Administrator with respect thereto; in which case, all
costs and expenses incurred in connection therewith shall be borne by
Administrator and shall be included in Administrator Expenses, and Administrator
shall be entitled to all damages and other amounts recovered thereby. In the
event the Purchase Assets are acquired by the Group pursuant to Article X, the
obligation of the Group to enforce Restrictive Covenants shall be limited to
enforcement of non-solicitation and nondisclosure of confidential/proprietary
information covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period,


                                       31
<PAGE>   37
scope of activity restricted and/or the geographical area applicable to such
provision of the Restrictive Covenants or this Article VI. The invalidity or
non-enforceability of any provision of the Restrictive Covenants or this Article
VI in any respect shall not affect the validity or enforceability of the
remainder of the Restrictive Covenants or this Article VI or of any other
provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Stockholder or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Stockholder or Full-time Physician Employee from the restrictive
covenants contained in Section 6.2, above. In the event the Group elects to
release such Group Physician Stockholder or Full-time Physician Employee, the
Group hereby covenants that it shall obtain a formal agreement between each
Group Physician Stockholder or Full-time Physician Employee, as the case may be,
and Administrator which provides that, for a period of two (2) years following
termination of any employment agreement with the Group, such Group Physician
Stockholder or Full-time Physician Employee agrees to (a) engage Administrator
as the sole and exclusive manager and administrator of the non-medical functions
and services of said Group Physician Stockholder's or Full-time Physician
Employee's medical practice and (b) pay to Administrator the identical amount
[NY only] of revenues paid by the Group to the Administrator attributable to
such Group Physician Stockholder or Full-time Physician Employee derived from
such Group Physician Stockholder's or Full-time Physician Employee's performance
of professional medical services within 15 miles of any Practice Site.

         Section 6.6 Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary
information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and


                                       32
<PAGE>   38
work effort required and (y) the Group shall not be required to employ any
Radiologist previously associated with such Professional Service Opportunity.

         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half of the time during which the
Administrator, Parent or their Affiliates must respond to an offer described in
the Administrator's Notice, the Group shall deliver to Administrator a written
notice stating whether or not the Group elects to accept or reject the New
Professional Service Opportunity which election shall be binding on the Group.
If the Group does not elect to exercise the right or fails to provide the notice
to Administrator within the time frame herein provided, Administrator shall be
released from the right of first offer with respect to that particular New
Professional Service Opportunity. Prior to consummating any asset acquisition,
merger or other consolidation of any Radiologist, group of Radiologists, or
professional corporation or association (or other professional entity) whose
owners are Radiologists within any Secondary Service Area, Administrator shall
first consult with the Joint Planning Board.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service
Opportunity as contemplated in subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

             "New Professional Service Opportunity" shall mean a Professional
Service Opportunity pursuant to which the Group or any other member of an APPI
Group managed by Parent, Administrator or their Affiliates is not currently
providing professional Radiology services.

             "Primary Service Area" shall mean that area within a five (5) mile
radius from any imaging center owned, operated or managed by Administrator,
Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.


                                       33
<PAGE>   39
             "Professional Service Opportunity" shall mean any opportunity to

             "Radiology" shall mean and include diagnostic imaging,
interventional radiology and radiation oncology services.

             "Secondary Service Area" shall mean (i) during the 12-month period
following the Acquisition Effective Date, that area which extends ten (10) miles
beyond the boundary of any Primary Service Area and (ii) during the remaining
term of this Agreement, that area which extends five (5) miles beyond the
boundary of any Primary Service Area.

         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.


                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on


                                       34
<PAGE>   40
Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates based
upon available information for such month, and adjustments to the estimated
payments shall be made to reconcile final amounts due under Section 7.1 on the
next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee


                                       35
<PAGE>   41
and to other related provisions of this Agreement shall be a joint decision of
the parties, shall be memorialized in a written amendment to this Agreement, and
shall be based upon the methodology used to generally determine Services Fees
hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

         (a)      payment of all accrued Practice Expenses for the prior month
                  (subject to the proviso in the preceding sentence;

         (b)      payment of the accrued Service Fee for the prior month;

         (c)      payment of outstanding balance of all amounts advanced to the
                  Group, through the end of the prior month, and applicable
                  interest thereon (as contemplated in Section 7.3); and

         (d)      payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).


                                  ARTICLE VIII

                                     Records

         Section 8.1 Records. All records relating in any way to the operation
of the Practice (other than Group Records) shall, subject to the obligations of
the Practice to maintain patient medical records pursuant to Section 3.2(g), at
all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter, the
Group or its agents shall have reasonable access during normal business hours to
the Group's and Administrator's personnel and financial records relating to the
Practice, including, but not limited to, records of collections, expenses and
disbursements as kept by Administrator in


                                       36
<PAGE>   42
performing Administrator's obligations under this Agreement, and the Group may
copy any or all such records.


                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1 Insurance to be Maintained by the Group.

         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.


                                       37
<PAGE>   43
         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.

         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5 Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its shareholders, employees
and/or subcontractors (other than Administrator, Parent, Affiliates or their
employees, officers, directors, agents, attorneys and consultants) during the
term of this Agreement. Provided, however, that in the event an indemnification
obligation under the preceding sentence arises as of the result of any act or
omission of a person who is an officer, shareholder or other equity holder,
director, employee, agent, attorney or consultant of Administrator, Parent or
any of their Affiliates (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
the Group's indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or
incurred, that are caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts or omissions by Administrator, Parent or Affiliates and/or any of
their respective shareholders, employees and/or subcontractors (other than the
Group or its employees) during the term of this Agreement. Provided, however
that


                                       38
<PAGE>   44
in the event an indemnification obligation under the preceding sentence arises
as a result of any act or omission of a person who is an officer, shareholder or
other equity holder, director, employee, agent, attorney or consultant of the
Group (other than in connection with the activities of the Joint Planning
Board), such person shall not be entitled to indemnification in connection
therewith and any other adjustment as is equitable shall be made to
Administrator's or Parent's indemnification obligation arising thereby.

written notice of such party's intention not to extend the term of this
Agreement.

         Section 10.3 Termination by the Group. The Group may, in its sole
discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not


                                       39
<PAGE>   45
the obligation, to cure any Material Adminstrator Default. Notwithstanding
anything to the contrary in this Agreement, following receipt by Administrator
of the notice of a Material Administrator Default and until such Material
Administrator Default shall be cured, the Group may take such action as may be
reasonably required to cover such Material Administrator Default so as to
maintain for the Group the same level of service as before the Material
Administrator Default, without prejudicing in any way the Group's other rights
and remedies, and may offset all of its costs from the amounts which may
otherwise be due to Administrator under this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that


                                       40
<PAGE>   46
individual from participating in or from receiving reimbursement under any
program funded by the federal government or by any state government,
notwithstanding any available post-sanction remedies, or (4) is otherwise
disciplined by any licensing, regulatory or professional entity or institution,
the result of any of which event does or is reasonably expected to materially
adversely affect the Practice, the result of any of which event described in
subparagraphs (1) through (4) above, in the absence of termination of a
Physician Employee or a Physician Extender Employee or other action of the Group
to monitor and cure such act or conduct by such employee, does or reasonably
would be expected to materially and adversely affect the Practice or the Group.
Notwithstanding anything to the contrary in this Agreement, following receipt by
the Group of the notice of a Material Group Default, and until such Material
Group Default shall be cured, the Administrator may take such action as may be
reasonably required to cover such Material Group Default so as to maintain for
the Administrator the same level of service at the Premises as before the
Material Group Default, without prejudicing in any way Administrator other
rights and remedies, and may offset all of its costs of cover from amounts which
may otherwise due to the Group under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Stockholders and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
(with the exception of Hector Correa, Nancy Sussman, M.D., or Herbert Z. Geller)
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee [or Physician Extender Employee] that intends to
retire prior to expiration of such five-year period, then such Physician
Employee or Physician Extender Employee shall not be counted for purposes of
determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator and/or Parent, the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or their
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's or their Affiliates' accounting and financial records (the "Purchase
Assets"), including, but not limited to, without duplication, (i) all equipment,
furniture, fixtures, furnishings, inventory, supplies, improvements, additions
and leasehold improvements utilized by the Practice, (ii) any real estate owned
by Administrator, Parent or Affiliates that is occupied by or used primarily for
the benefit of the Practice, (iii) all unamortized intangible assets (including,
without limitation, goodwill) set forth on the financial statements of
Administrator, Parent or their Affiliates used solely in connection with the
Practice or otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and their Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c) Purchase Price. The Purchase Price shall be the lesser of (i) Fair
Market Value of the Purchase Assets subject to the assumption of the Practice
Related Liabilities or (ii) the value of the Actual Consideration (defined
below)(alternatively, the "Purchase Price"); provided, however, the Purchase
Price shall not be less than the net book value of the Purchase Assets at the
Termination Date. The Purchase Price shall be paid pursuant to Section 10.7. For
purposes of this subparagraph (c), the term "Actual Consideration" shall mean
(i) cash consideration paid to the Group pursuant to the Acquisition Agreement
and (2) an amount equal to the number of shares of Parent Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, reorganizations,
or any similar transaction whereby the Parent Common Stock is increased or
decreased or exchanged for a different number or kind of securities) issued
pursuant to the Acquisition Agreement multiplied by the fair market value of
Parent Common Stock immediately prior to the time that a Termination Notice is
provided pursuant to Section 10.7. The Purchase Price shall be appropriately
adjusted to offset and account for any monetary obligations of the Group or
Administrator owing to the other as provided herein.


                                       42

         (d) Exercise of Option.

                  (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                  (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

         (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at the Purchase Closing, Administrator and/or its Affiliates, as the case
may be, shall transfer and assign the Purchase Assets to the Group, and in
consideration therefor, the Group shall (a) pay to Administrator, Parent and/or
their Affiliates an amount in cash or, at the option of the Group (subject to
the conditions set forth below), Parent Common Stock (valued pursuant to Section
10.6(c) hereof), or some combination of cash and Parent Common Stock equal to
the Purchase Price and (b) assume the Practice Related Liabilities. The
structure of the transaction set forth in this Section 10.7 shall, if possible,
be structured as a tax-free transaction under applicable law. Each party shall
execute such documents or instruments as are reasonably necessary, in the
opinion of each party and its counsel, to effect the foregoing transaction. The
Group shall, and shall use its best efforts to cause each shareholder of the
Group to, execute such documents or instruments as may be necessary to cause the
Group to assume the Practice Related Liabilities and to release Administrator,
Parent and/or their Affiliates, as the case may be, from any liability or
obligation with respect thereto. In the event the Group desires to pay all or a
portion of the Purchase Price in shares of Parent Common Stock, such transaction
shall be subject to the satisfaction of each of the following conditions:


                                       43
<PAGE>   49
         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims, proxies, options, stockholders' agreements
and encumbrances (not including any applicable securities restrictions and
lock-up arrangements with the Parent or any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain financing for such acquisition but is unable to
obtain such financing and (iii) there is either a Material Administrator Default
pursuant to Section 10.3(a) or (c) or a Material Group Default pursuant to
Section 10.4(b) triggering a sale of the Purchase Assets, the Group shall be
entitled to obtain financing from Administrator, Parent and/or their Affiliates
but only for the difference between the Fair Market Value of the Purchase Assets
and the net book value of the Purchase Assets. The terms of such financing shall
be for a five (5) year period at an interest rate equal to the prime rate (as
published in the Wall Street Journal) plus four percent (4%) or such lesser rate
as is required to be in conformance with all applicable state and federal law.
In the event the Group is entitled to obtain financing from Administrator,
Parent and/or their Affiliates, the Group shall execute and deliver to
Administrator, Parent and/or their Affiliates all such documentation necessary
and appropriate to effectuate the financing transaction including, without
limitation, a secured promissory note, security agreement and financing
statements and such documentation shall contain such representations, warranties
and conditions customary to a secured transaction of this size.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator, Parent and/or their Affiliates to the
Group or the Group to the Administrator, Parent and/or their Affiliates


                                       44
<PAGE>   50
(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

         (a) Administrator, Parent and/or their Affiliates shall use their best
efforts to cooperate with the Group for the appropriate transfer of management
services.

         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.

         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.


                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

         Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means


                                       45
<PAGE>   51
set forth in Section 11.1 and prior to commencing an arbitration procedure
pursuant to this Article XI, the parties shall meet to discuss and consider
other alternative dispute resolution procedures other than arbitration,
provided, however that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including rules of
evidence and procedure. If at any time prior to the rendering of the decision by
the arbitrator (or pursuant to such other alternative dispute resolution
procedure) as contemplated in this Article XI to the extent a party makes a
written offer to the other party proposing a settlement of the matter(s) at
issue and such offer is rejected, then the party rejecting such offer shall be
obligated to pay the costs and expenses (excluding the amount of the award
granted under the decision) of the party that offered the settlement from the
date such offer was received by such other party if the decision is for a dollar
amount that is less than the amount of such offer to settle. Notwithstanding the
foregoing, the terms and provisions of this Article XI shall not preclude any
party hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

         Section 11.3 Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among Administrator and the Group arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within 30 days of notice
by a party to the other of its desire to seek arbitration under this Article XI
one arbitrator mutually acceptable to Administrator and the Group to hear and
decide all such claims under this Article XI. If such matter or action involves
health-care issues, then the arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators proposed shall be impartial
and independent of all parties. If the parties cannot agree on the selection of
an arbitrator within said 30-day period, then any party may in writing request
the judge of the United States District Court for the Southern District of New
York (White Plains) senior in term of service to appoint the arbitrator and,
subject to this Article XI, such arbitrator shall hear all arbitration matters
arising under this Article XI.

         Section 11.4 Applicable Rules.

         (a) Each arbitration hearing shall be held at a place in Weschester or
Rockland Counties, New York, acceptable to the arbitrator. The arbitration shall
be conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof. The decision of the arbitrator shall be reduced to writing and shall be
binding on the parties and such decision shall contain a concise statement of
the reasons in support of such decision. Judgment upon the award(s) rendered by
the arbitrator may be entered and execution had in any court of competent
jurisdiction or application may be made to such court for a judicial acceptance
of the award and an order of enforcement. The charges and expenses of the
arbitrator shall be shared equally by the parties to the hearing.


                                       46
<PAGE>   52
         (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI. In
fulfilling his duties with respect to determining the amount of any loss, the
arbitrator may consider such matters as, in the opinion of the arbitrator, are
necessary or helpful to make a proper valuation. The arbitrator may consult with
and engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

         (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.

         (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e) All privileges under New York and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying New York law.


                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment.

         (a) Administrator shall have the right to assign its rights hereunder
to Parent or any direct or indirect wholly-owned subsidiary of Administrator or
Parent (that remains a wholly-owned subsidiary of Administrator or Parent) or to
a financial institution as collateral security for the indebtedness of Parent,
Administrator or their Affiliates without the consent of the Group. No
assignment under subsection (a) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         (b) Administrator, Parent and their Affiliates shall provide notice to
the Group of Administrator's intent (i) to assign this Agreement (other than as
permitted in Section 12.1(a) herein), (ii) sell all or substantially all of the
assets of Administrator or (iii) effectuate a consolidation, merger or sale of a
majority of the capital stock of Administrator as soon as practicable following
a decision by the Parent's and Administrator's respective boards of directors to
seek such assignment or sale. The assignment of this Agreement (other than as
permitted in Section 12.1(a)), the sale of all or substantially all of the
assets of Administrator by Parent or a consolidation, merger or sale of a
majority of the capital stock of Administrator


                                       47
<PAGE>   53
shall not be permitted unless Administrator shall give written notice to the
Group stating the party who made the offer and specifying the purchase price
offered (the "Notice"). The Group shall have the option to repurchase the
Purchase Assets on the same terms and conditions set forth in the Notice. In the
event the Group fails to provide written notice to Administrator of its intent
to exercise its option to repurchase the Purchase Assets pursuant to this
Section 12.1 within the earlier of (i) thirty (30) days or (ii) one-half of the
time during which Administrator, Parent or their Affiliates must respond to an
offer following the Group's receipt of the Notice, the option contained in this
Section 12.1 shall be deemed null and void and of no further force and effect,
and Administrator shall be free to assign the Agreement, sell all or
substantially all of the assets of Administrator or sell or transfer all of the
capital stock Administrator without the consent of the Group. No assignment
under this subsection (b) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

         Section 12.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 12.4 Additional Documents. Each of the parties hereto agrees to
execute any document or documents that may be reasonably requested from time to
time by the other party to implement or complete such party's obligations
pursuant to this Agreement.

         Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,
costs and expenses including, but not limited to, attorney's fees, costs and
expenses for trial, appellate proceedings and negotiations, in addition to any
other relief granted.

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group
and Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this

and that nothing herein shall be construed as the practice of medicine by
Administrator or Parent. To the extent any act or service required of
Administrator is construed or deemed to constitute the practice of medicine,
Administrator is released from any obligation to provide, and the Group shall be
deemed not to have requested Administrator to provide, such act or service
without otherwise affecting the other terms of this Agreement.

         Section 2.3 No Payment or Other Compensation for Referrals. The parties
hereby agree that the benefits to the Group hereunder do not require, are not
payment or compensation


                                       8
<PAGE>   14
in cash or in kind for, and are not in any way contingent upon the admission,
referral or any other arrangement for the provision of any item or service
offered by Administrator or any of its Affiliates to any of the Group's patients
in any facility controlled, managed or operated by Administrator.

         Section 2.4 Group's Internal Matters. The Group shall be solely
responsible for matters involving its corporate governance, employees and
similar internal matters, including, but not limited to, preparation and
contents of such reports to regulatory authorities governing the Professional
Operations that the Group is required by law to provide, and distribution of
salaries and professional fee income among the Group Physician Stockholders,
Physician Employees and Physician Extender Employees. Administrator shall assist
the Group, where necessary and appropriate, by providing the information and
data to be included in such reports.


                                   ARTICLE III

                    Services to be Provided by Administrator

         Section 3.1 General.

         (a) Scope of Services Provided. Administrator shall provide or arrange
for the services set forth in this Article III, and the costs, fees, expenses
and other disbursements incurred by Administrator or Parent in connection
therewith shall be included in Practice Expenses, except to the extent such
costs, fees or expenses are expressly included in Excluded Practice Expenses or
Administrator Expenses. Administrator is authorized to perform its services
hereunder as is necessary or appropriate for the efficient operation of the
Practice, including, without limitation, performance of some of the business
office functions at locations other than the Practice. Except to the extent
necessary to comply with applicable laws, regulations or professional ethical
standards, the Group will not act in a manner which would prevent Administrator
from performing its duties hereunder and will provide such information and
assistance to Administrator as is reasonably required by Administrator to
perform its services hereunder. Administrator shall cause its employees, to
comply with all applicable federal, state and local laws, rules and regulations
in Administrator's provision of services hereunder.

         (b) Alternative Management Arrangements.

                  (i) If Administrator fails to perform, provide or arrange for
the services set forth in this Article III in a manner reasonably consistent
with commercially available services offered by third party providers of
physician practice management services of the type and scope offered by
Administrator, then the Group shall provide written notice of such event to
Administrator, Parent or their Affiliates, including reasonable evidence of such
commercially available services. Administrator shall deliver to the Group within
thirty (30) days after receipt by Administrator of such written notice a written
plan detailing the methods and procedures Administrator, Parent or their
Affiliates shall utilize to restore the level of service contemplated


                                       9
<PAGE>   15
by this Agreement. In the event Administrator fails to restore the level of
service contemplated by this Agreement in accordance with such plan submitted or
in any event within ninety (90) days, the Group shall be entitled to
reimbursement by Administrator for the reasonable costs and expenses of
obtaining such service on a temporary basis until such time Administrator
demonstrates its ability to perform such service at the level contemplated by
this Agreement. Nothing contained in this subsection (b)(i) shall be construed
to limit the Group's ability to provide notice of a Material Administrator
Default pursuant to Section 10.3(b) of this Agreement.

                  (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service
is construed or deemed to constitute the practice of medicine, Administrator
shall deliver to the Group notice of such an event. The Group shall be entitled
to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

         Section 3.2 General Administrative Services.

         (a) Exclusive Management Services; Scope of Services. Except as
provided in Exhibit 3.2(a), the Group hereby engages Administrator to serve as
its exclusive manager and administrator of non-medical business services
relating to the operation of the Practice, subject to matters reserved for the
Group or referred to the Joint Planning Board as herein contemplated, and
Administrator shall have all necessary authority and hereby agrees to perform
such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

         (b) Billing and Collection.

                  (i) Administrator shall, in the name of and on behalf of the
Group, bill patients, insurance companies, Managed Care Payors, and other
third-party payors and collect all fees for services rendered in connection with
the Practice at the Premises or any Practice Site(s) (including all fees
generated by both the Technical Operations and the Professional Operations), for
services performed outside the Practice for its hospitalized patients, and for
all other professional and Practice services. The Group hereby appoints
Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:


                                       10
<PAGE>   16
                           (A) to bill patients, insurance companies, Managed
Care Payors, and other third-party payors in the Group's name and on its behalf;

                           (B) to collect accounts receivable resulting from
such billing not otherwise purchased by Administrator (as provided for in
Section 3.2(e) hereof) in the Group's name and on its behalf;

                           (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                           (D) to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                           (E) to take possession of and endorse in the name of
the Group and deposit into the Deposit Account (and/or in the name of an
individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                           (F) upon the prior consent of the Group, which
consent shall not be unreasonably withheld or delayed, to initiate the
institution of legal proceedings in the name of the Group or a Physician
Employee to collect any accounts and monies owed to the Group or the Physician
Employee, to enforce the rights of the Group or the Physician Employee, as the
case may be, as creditor under any contract or in connection with the rendering
of any service, and to contest adjustments and denials by governmental agencies
(or their fiscal intermediaries) as third-party payors.

                  (ii) The Group hereby appoints Administrator as its true and
lawful attorney-in-fact to deposit into the Deposit Account all Professional
Revenues and Technical Revenues collected by Administrator as provided for in
this Section 3.2(b). The Group covenants, and shall cause all Physician
Employees and Physician Extender Employees to covenant, to forward any payments
received with respect to any Professional Revenues or Technical Revenues
generated for services provided by the Group or any of its Physician Employees
and Physician Extender Employees to Administrator for deposit. Administrator
shall have the right to withdraw funds from the Deposit Account and all owners
of the Deposit Account shall execute a revocable standing transfer order (the
"Transfer Order") under which the bank maintaining the Deposit Account shall
periodically transfer the entire balance of the Deposit Account to a separate
bank account owned solely by Administrator (the "Administrator Account"). The
Group and Administrator hereby agree to execute from time to time such documents
and instructions as shall be required by the bank maintaining the Deposit
Account and mutually agreed upon to effectuate the foregoing provisions and to
extend or amend such documents and instructions. Any action by the Group that
materially interferes with the operation of this Section, including but not
limited to, any failure to deposit or to have Administrator deposit any


                                       11
<PAGE>   17
Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit Account not authorized by the express
terms of this Agreement or any other written agreement executed by each of the
parties, or any revocation of or attempt to revoke the Transfer Order (otherwise
than upon expiration or termination of this Agreement), will constitute a breach
of this Agreement and will entitle Administrator, in addition to any other
remedies it may have at law or in equity, to seek a court ordered assignment of
the rights provided to Administrator pursuant to subparagraph (i) above.

                  (iii) All monies shall be accounted for by Administrator as
being distinctly attributable to the Group. The Group may perform the functions
or exercise the rights set forth in this Section 3.2(b) only with the prior
written consent of Administrator. The Group shall execute such documents in form
and substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c) Accounting. Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of
the Practice, and Administrator shall perform all bookkeeping and accounting
services necessary or appropriate for the efficient operation of the Practice,
including the maintenance, custody and supervision of business records, ledgers
and reports; the establishment, administration and implementation of accounting
procedures, controls and systems; and implementation and management of
computer-based management information systems. The Group and its authorized
representatives shall have the right to review all financial books and records
maintained by Administrator relating to the operation of the Practice and to the
cash management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the parties have
agreed herein. The purchase price shall be an amount equal to the aggregate face
amount of the accounts receivable being sold less contractual adjustments and


                                       12
<PAGE>   18
estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

         (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication
services and medical transcribing services; provided, however, that the Group
may elect to prepare its own Tax Returns, in which case, the cost of preparing
such Tax Returns in excess of $2,500 per annum shall be included in Excluded
Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group
containing a balance sheet, income statement and monthly operational reports
which detail payments, charges and accounts receivable statistics, monthly
reconciliation reports on cash management and any other financial reports
reasonably requested by a member of the Joint Planning Board designated by the
Group, which shall be delivered to the Group as soon as practicable, but no
later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

         (g) Records and Files.

                  (i) Administrator's Business and Financial Records. At all
times during and after the term of this Agreement, including any extensions or
renewals hereof, all business records, including but not limited to, business
agreements, books of account, personnel records, general administrative records
and all information generated under or contained in the management information
system pertaining to Administrator's obligations hereunder, and other business
information of Administrator of any kind or nature, except for patient medical
records and the Group's Records (as defined in subparagraph (ii) below), shall
be and remain the sole property of Administrator; provided that during and after
termination of this Agreement, the Group shall be entitled to reasonable access
to such records and information, including the right to obtain copies thereof in
any media reasonably requested by the Group, for any purpose related to patient
care or the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years. Administrator hereby agrees
to preserve the confidentiality of such patient medical records and to use the
information in such records only for the limited purposes necessary to perform
management services and, within the limits of its responsibilities hereunder, to
ensure that provision is made for appropriate care for patients of the Practice.

<PAGE>   19
                  (ii) The Practice's Business and Financial Records. At all
times during and after the term of this Agreement, the business agreements,
financial, operational, corporate and personnel records and information relating
exclusively to the business and activities of the Group and patient medical
records and charts (hereinafter referred to as the "Group's Records") shall be

                  (iii) Access to Records. At all times during and after the
term of this Agreement, each party and its authorized agents shall be entitled,
upon request and with reasonable advance notice, to obtain access (within not
more than 30 days following receipt of such notice by the other party or
parties) to all records of the other party directly related to the performance
of such party's obligations pursuant to this Agreement; provided, however, that
such right shall not allow for access to patient, medical and other records that
must be kept confidential as required by law. Either party, at its expense,
shall have the right to make copies in any media of any records to which it has
access pursuant to this subparagraph (iii).

                  (iv) Compliance with Law. The management of all files and
records by Administrator and the Group shall comply with all applicable federal,
state and local statutes and regulations.

         (h) Collections. Subject to the consent requirement contained in
Section 3.2(b)(i)(F), Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees and
pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

         Section 3.3 Facilities.

acquired by Administrator or Parent (subject to review and approval of the Joint

                                       14
<PAGE>   20
         (c) Expenses. All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the
Premises and the Personal Property, including, without limitation, all
reasonably necessary costs of repairs, maintenance and improvements, utility

disposal, real or personal property lease cost payments and expenses, interest,
refinancing expenses, depreciation, loss on disposition of assets, taxes and

To the extent the Premises or Personal Property are used in connection with the
Professional Operations, the costs and expenses associated with such usage shall
be allocated between Professional Expenses and Technical Expenses as approved by
the Joint Planning Board.

         (d) Disposition. Subject to provisions contained in existing agreements
to which Administrator or Parent is or becomes a party and, where necessary and
appropriate for the efficient operation of the Practice, nothing herein shall be
construed as precluding Administrator or Parent from selling, leasing or
otherwise disposing of all or any part of the Premises, Personal Property, real
property, improvements, trade names, trademarks and other intangible property;
provided, however, any such sale, lease or disposition shall be subject to the
prior review and approval of the Joint Planning Board and shall not eliminate or
diminish Administrator's obligations hereunder.

         (e) No Warranties or Representations. The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

         Section 3.4 Acquisition and Assistance.

         (a) Employment of Physicians. Subject to consultation with the Joint
Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice. Subject to
consultation with the Joint Planning Board, in the event that a decision is made
by the Group to pursue the employment of selected physicians, if requested by
the Group, Administrator will provide recruiting, consulting, negotiating and
other advisory services in connection with such transaction. Notwithstanding the
preceding, as set forth in and subject to the provisions of Section 4.1 hereof,
the Group shall have complete control of and responsibility for the hiring of
all Physician Employees and Physician Extender Employees.

         (b) Acquisitions. In the event that the Group contemplates acquiring or
affiliating with a physician group, practice or other entity, and such
acquisition or affiliation involves the use or expenditure of Administrator's
and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a
result of such an acquisition or affiliation including, without limitation,
capital and personnel (collectively, the "Resources"), then the Group shall
first consult with the Joint Planning Board and Administrator, and any decision
to make such affiliation or acquisition shall


                                       15
<PAGE>   21
be subject to prior approval of Administrator, which decision of the
Administrator shall be provided to the Group in a reasonable and timely manner
following satisfactory review of the physician group, practice or other entity
to be acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto. If such contemplated acquisition or affiliation does not
involve the use or expenditure of any of Administrator's and/or Parent's
Resources, then such decision shall be in the sole discretion of the Group.
Notwithstanding any provision contained herein to the contrary, any person or
entity with which the Group affiliates or acquires shall be subject to the terms
and conditions of this Agreement. If a decision is made to proceed with any
affiliation or acquisition of a physician group or practice, the Group may seek
from Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

         Section 3.5 Financial Planning and Budgeting.

         (a) Budgeting. Administrator shall collaborate with the Group and the
Joint Planning Board in the preparation of all annual capital and operating
budgets. These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors. For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board. The
projected annual operating budget for each subsequent year shall be subject to
the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice. For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

         (b) Capital Expenditures. Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

                  (i) Budgeted Expenditures. All budgeted capital expenditures
and improvement projects shall be subject to final review and approval by the
Joint Planning Board prior to the making of any actual expenditure. Such review
and approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.

                  (ii) Non-Budgeted Expenditures. Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared by
the Joint Planning Board in consultation with the Group and Administrator. All
requests for non-budgeted capital


                                       16
<PAGE>   22
expenditures and improvements at or for the benefit of the Practice in excess of
either $75,000 individually or an aggregate amount equivalent to $2,500
multiplied by the number of Full-time Physician Employees employed at the time
the capital budget for such Group for the applicable year is determined
(provided, however, that such aggregate amount shall not exceed $250,000 for any
calendar year) must be approved by the Board of Directors of Parent or by any
committee specifically designated by the Board of Directors of Parent for such
purposes.

         (c) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
[If the Group is dissatisfied with the services of any such personnel who
provide services primarily for the Practice at the Premises, the Group shall
consult with Administrator, and Administrator shall in good faith determine
whether the performance of that employee could be brought to acceptable levels
through counsel and assistance, or whether such employee should be considered
for termination. Such Personnel shall be supervised by and comply with the
directions and orders of Administrator, except as otherwise required by
applicable law. If Administrator determines to retain such employee and the
Group is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors"). Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning Board,
be the responsibility of the Group. Notwithstanding the preceding language, if a
contract or relationship between any Managed Care Payor and the Group involves
or affects a contract or relationship with any other physician group or practice
serviced or managed by Administrator,


                                       17
<PAGE>   23
Parent or any of their Affiliates (the "Other Practices") and a consensus among
the Group and the Other Practices cannot be reached regarding the contract or
relationship, then the ultimate decision as to the approval, disapproval,
termination or amendment of such contract or relationship involving the Group,
the Other Practices and such Managed Care Payor shall be determined by the
affirmative vote of the Physician Board Members (as defined below) who hold a
majority of the Group Voting Power (as defined below). For purposes of this
Section 3.7, (i) the term "Physician Board Members" shall mean (a) those members
appointed by the Group who serve on the Joint Planning Board and (b) those
persons appointed by the Other Practices who serve on the Other Practices' joint
boards (in a similar capacity to the Joint Planning Board) as part of their
contractual relationship with Parent, Administrator or any of their Affiliates,
and (ii) the term "Group Voting Power" shall mean the total voting percentage
which may be cast by the Physician Board Members on a collective basis, with the
percentage of votes able to be cast by any Group or Other Practice, as
applicable, shall be equal to the quotient determined by dividing (x) the total
estimated annual professional revenues to be generated by the Group from such
Managed Care Contract as determined by Administrator, Parent or their
Affiliates, as appropriate, in its sole discretion, by (y) the total estimated
annual professional revenues to be generated by the Group and all Other
Practices from such Managed Care Contract as determined by the Administrator,
Parent or their Affiliates, as appropriate, in its sole discretion.

         Section 3.8 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.9 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and advertising programs shall be
conducted in compliance with applicable standards of medical ethics, laws and
regulations.

         Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain

<PAGE>   24
provided, however, that any expenses related to such program that are incurred
for services provided solely for the direct benefit of the Practice shall be
included in Practice Expenses.

         Section 3.11 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by

limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

         Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.


                                   ARTICLE IV

                            Obligations of the Group

         Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender
Employees, and other employees who may have malpractice exposure or liability,
are insurable and by participating in an ongoing risk management program.

         Section 4.2 Professional Services. The Group shall provide professional
services to its patients in compliance at all times with ethical standards,
laws, rules and regulations applicable to the operations of the Practice, the
Physician Employees and Physician Extender


                                       19
<PAGE>   25
Employees. The Group shall ensure that each Physician Employee and each
Physician Extender Employee has all required licenses, credentials, approvals or
other certifications to perform his or her duties and services for the Practice
and, in the event that the Group becomes aware of any disciplinary actions or
medical malpractice actions initiated against any Physician Employee or
Physician Extender Employee, the Group shall promptly inform Administrator of
such action and the underlying facts and circumstances. If required by
applicable law, any state or federal regulatory agency or any contractual
obligations, the Group shall carry out a program to monitor the quality of
medical care practiced at the Practice; provided, however, that the preceding
language shall not limit the Group's obligation to participate in or comply with
any programs established by Administrator or Parent for purposes of ensuring
that the Group complies with applicable law. The Group shall employ Physician
Employees and Physician Extender Employees as is necessary to provide efficient
medical care to patients of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery
items on prepaid Managed Care Contracts which are authorized and permitted by
such contracts. A copy of such agreements and any amendment thereto shall be
provided to Administrator for review no later than thirty (30) days prior to the
proposed effective date thereof.

         Section 4.4 Group's Internal Matters. The Group shall be responsible
for matters involving its corporate governance, employees and similar internal
matters, including, but not limited to, preparation and contents of such reports
to regulatory authorities governing the Group that the Group is required by law
to provide, distribution of professional fee income among the Group Physician
Stockholders, disposition of the Group's property and stock (subject to any
restrictions contained herein), hiring and firing of its employees, licensing
and implementing all compliance plans and procedures as described in Section
4.6. Except for the expenses attributable to the distribution of professional
fee income among the Group Physician

<PAGE>   26
Stockholders, which will be included in Excluded Practice Expenses, the costs
incurred in connection with the foregoing matters shall be Practice Expenses.

         Section 4.5 Name. Administrator agrees that the Group shall be entitled
to use on a non-exclusive and non-transferable basis for the term of this
Agreement the names set forth on Schedule 4.5 as may be necessary or appropriate
in the performance of the Group's services and obligations hereunder.

         Section 4.6 Compliance with Laws. The Group shall, and shall use its
best efforts to cause the Physician Employees, Physician Extender Employees and
other employees of the Group to, comply with all applicable federal, state and
local laws, rules, regulations and restrictions in the conduct of the Practice's
business. Without limiting the generality of the foregoing, the Group shall
comply and shall cause each Physician Employee, Physician Extender Employee and
other employee of the Group to comply, with all laws applicable to the operation
of the Practice in the generation, transportation, treatment, storage, disposal
or other handling of radioactive, medical, biological or hazardous materials or
waste, and the Group shall not, and shall use its best efforts to prohibit any
Physician Employee, Physician Extender Employee and any employee of the Group

otherwise generate business for, the Practice, if such transaction is in
violation of any applicable law, rule or regulation;

         (b) knowingly and willfully making or causing to be made a false
statement or representation of a material fact in any application for any
benefit or payment from a Managed Care Payor or any other Payor;

any event affecting the initial or continued right to any benefit or payment on
its own behalf or on behalf of another, with intent to fraudulently secure such

remuneration (i) in return for referring an individual to a person for the
furnishing or arranging for the furnishing of any item or service for which
payment may be made in whole or in part by Medicare or Medicaid, or (ii) in
return for purchasing, leasing, or ordering, or arranging for or recommending
purchasing, leasing, or


                                       21
<PAGE>   27
ordering any good, facility, service, or item for which payment may be made in
whole or in part by Medicare or Medicaid; and

         (f) referring a patient for health services or products to or providing
health services to a patient upon a referral from an entity or person with which
the physician or an immediate family member has a financial relationship, other

or regulations; and

         (g) undertaking any action that is not in accord with the regulatory
compliance plans, policies and manuals developed by or in conjunction with
Administrator.

         Section 4.7 Ancillary Services. Except as set forth in Section 3.4(b),

the express written consent of Administrator, which consent shall not be
unreasonably withheld.

         Section 4.10 Events Excusing Performance. In the event of strikes,

         Section 5.1 Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy is counted;
provided, however, that no proxy shall be valid after the expiration of eleven
(11) months from the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2 Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

         (a) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be


                                       23
<PAGE>   29
based upon economic feasibility, productivity and then current market conditions
in light of both the particular project and the Group as a whole.

         (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess
of five percent (5%) to the annual capital or operating budgets.

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

         (d) Patient Fees. As a part of the annual operating budget, in
consultation with and upon recommendation of the Joint Planning Board, the Group
shall review and adopt the fee schedule for all professional services rendered
by the Practice.

         (e) Ancillary Services and Fees. The Joint Planning Board shall approve
Practice-provided non-medical ancillary services (including, without limitation,
fees for technical services which do not generate Professional Revenues) based
upon the pricing, access to, and quality of such services and shall review and
adopt the fee schedule for all ancillary services.

         (f) Provider and Payor Relationships. Subject to Section 3.7, decisions
regarding the establishment or maintenance of relationships with institutional
health care providers and payors shall be approved by the Group after
consultation with the Joint Planning Board.

         (g) Strategic Planning. The Joint Planning Board shall develop a plan
which depicts the strategic direction of the Practice, as updated from time to
time. Such plan will, among other things, identify opportunities, objectives,
and the resources required to effect such plan.

         (h) Capital Expenditures. The Joint Planning Board shall determine the
priority of capital expenditures in accordance with Section 3.5(b) hereof.

         (i) Provider Hiring. The Joint Planning Board shall consult with the
Group to recommend the number and type of Physician Employees and Physician
Extender Employees required for the efficient operation of the Practice.

         (j) Non-Physician Personnel. The Joint Planning Board shall consult
with Administrator to recommend the number and type of non-physician employees
required for the efficient operation of the Practice.

         Section 5.3 Acts of the Joint Planning Board. Except as otherwise
specifically provided herein, the act of the members holding a majority of the
voting power of the Joint Planning Board shall be the act of the Joint Planning
Board. The Group agrees that, unless the

<PAGE>   30
following are approved in advance by the Joint Planning Board and such act of
the Joint Planning Board includes the approval by both of the members designated
by Administrator, it shall take no action or implement any decision that would
(i) require Administrator to expend funds or incur obligations beyond those set
forth under Sections 3.5 or 5.2 of this Agreement; (ii) have a material adverse
effect on the amount of Administrator's management fee under Article VII; or
(iii) otherwise have a material adverse effect on Administrator's financial
interests under this Agreement. Except as provided in the prior sentence, the
Group and Administrator hereby agree to be bound by the act of the Joint
Planning Board if such act was approved by the members holding at least a
majority of the voting power of the Joint Planning Board. No action of the Joint
Planning Board shall be effective unless authorized by the members holding a
majority of the voting power of the Joint Planning Board present or represented
by proxy at the applicable meeting. In the event that a matter cannot be
resolved by the Joint Planning Board due to a tie vote, and no compromise can be
reached, then either (x) the Board of Directors of Parent or (y) a committee
designated by the Board of Directors of Parent containing at least one (1)
physician member will make a final determination on the matter in dispute
provided that both the Group and Administrator shall have had an opportunity to
make a presentation to the Board of Directors of Parent or a committee thereof,
as applicable. A quorum of the Joint Planning Board shall consist of the members
holding a majority of the voting power of the Joint Planning Board, present in
person, by telephone, or by proxy and the quorum must remain for the duration of
the meeting.

         Section 5.4 Joint Planning Board Meetings. Meetings of the Joint
Planning Board may be held by telephone or similar communication equipment so
long as all members participating in a meeting can hear and speak to each other.

meetings and shall provide a copy of the minutes to the members within fifteen
(15) business days following each meeting.

         (a) Regular Meetings. The Joint Planning Board shall hold not less than
four (4) regular meetings each year, at such specific times and places as the
members may determine.

         (b) Special Meetings. A special meeting of the Joint Planning Board may
be called by fifty percent (50%) of the votes.

         (c) Notice Requirement. A member calling a special meeting must provide
all other members with ten (10) days' advance written or telephonic notice.
Notice must be given or sent to the member's address or telephone number as
shown on the records of the Joint Planning Board. Notice may be delivered
directly to each member or to a person at the member's principal place of
business who would reasonably be expected to communicate that notice promptly to
the member.

         (d) Waiver of Notice Requirement.

                  (i) Written Waiver, Consent or Approval. Notice of a special
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the


                                       25
<PAGE>   31
special meeting. Such waiver, consent or approval need not specify the purpose
of the special meeting. All such waivers, consents, and approvals shall be filed
with the Joint Planning Board records or made a part of the minutes of the
special meetings.

                  (ii) Failure to Object. Notice of special meeting need not be
given to any member who attends the special meeting and does not protest before
or at the commencement of the special meeting such lack of notice.

                  (iii) Quorum. The smallest number of members that hold votes
that exceed fifty percent (50%) of all voting power shall constitute a quorum of
the Joint Planning Board.

                  (iv) Proxies. The Joint Planning Board shall provide for the
use of proxies, telephonic conference calls, written consents or other

                              Restrictive Covenants

         The parties recognize that the services to be provided by Administrator

Practice devote their full medical time and attention. Accordingly, the parties 
hereto agree as follows:

         Section 6.1 Restrictive Covenants of the Group.

         (a) Noncompetition. During the term of this Agreement, the Group shall
not, without the prior written consent of Administrator, (i) establish, operate

enter into an agreement with any third party payor to provide such services,
(ii) enter into any other management or administrative services agreement or
other arrangement with any other person or entity (other than with
Administrator) for purposes of obtaining management, administrative or other

         (b) Covenant Not to Solicit. During the term of this Agreement and for
twenty-four (24) months following the termination of this Agreement, the Group
shall not, without the prior written consent of Administrator: (i) unless the

recruit or hire, or induce any party to recruit or hire any person who is an
employee of, or who has entered into an independent contractor arrangement with,
any member of the APPI Group; (ii) directly or indirectly, whether for itself or

         (c) Engagement of Administrator. If (i) this Agreement is terminated
pursuant to Section 10.4(a) or (c), and (ii) the Group does not acquire the
Purchase Assets as provided in Article X, then if the Group establishes,
operates or provides professional services at any office, practice, diagnostic
imaging center, hospital or other health care facility providing services
substantially similar to those provided by the Practice pursuant to this
Agreement anywhere within 15 miles of any location of any Practice Site(s), the
Group or any successor thereto shall engage Administrator as the sole and
exclusive manager and administrator of the nonprofessional functions and
services of such other office, practice, hospital or health care facility on the
same terms and conditions as contained herein.

         (d) Administration's Obligations Regarding Proprietary Interest.

                  (i) Acknowledgement of Proprietary Interest. Administrator,
Parent or their Affiliates hereto recognize the proprietary interest of the
Group in any Confidential and Proprietary Information (as hereinafter defined).
Administrator, Parent and their Affiliates acknowledge and agree that any and
all Confidential and Proprietary Information of the Group ("Group's Confidential
and Proprietary Information") communicated to, learned of, developed or
otherwise acquired by Administrator, Parent and their Affiliates during the term
of this Agreement shall be the property of the Group. Administrator, Parent and
their Affiliates further acknowledge and understand that disclosure of any of
Group's Confidential and Proprietary Information will result in irreparable
injury and damage to the Group. As used herein, "Group's Confidential and
Proprietary Information" means all trade secrets and other confidential and/or
proprietary information of the Group, including information derived from
reports, investigations, research, work in progress, codes, marketing and sales
programs, financial projections, cost summaries, pricing formula, contract
analyses, financial information, projections, confidential filings with any
state or federal agency, and all other confidential concepts, methods of doing

                  (ii) Covenant Not-to-Divulge Confidential and Proprietary
Information. Administrator, Parent and their Affiliates acknowledge and agree
that the Group is entitled to prevent the disclosure of Group's Confidential and
Proprietary Information. Administrator, Parent and their Affiliates agree at all
times during the term of this Agreement and thereafter to hold in strictest
confidence and not to disclose to any person, firm or corporation, except as


                                       27
<PAGE>   33
may be necessary for the discharge of its obligations under this Agreement, and
not to use, except in the pursuit of the business of the Practice, Group's
Confidential and Proprietary Information, without the prior written consent of
the Group; unless (i) such information becomes known or available to the public
generally through no wrongful act of Administrator, Parent or their Affiliates
or their employees or (ii) disclosure is required by law or the rule, regulation
or order of any governmental authority under color of law; provided, that prior
to disclosing any Group's Confidential and Proprietary Information pursuant to
this clause (iii), Administrator, Parent or their Affiliates shall, if possible,

opportunity to contest such disclosure. Administrator, Parent and their
Affiliates shall take all necessary and proper precautions against disclosure of
any of Group's Confidential and Proprietary Information to unauthorized persons
by any of its officers, directors, employees or agents. All officers, directors,
employees, and agents of Administrator, Parent and their Affiliates who will
have access to all or any part of the Group's Confidential and Proprietary
Information will be required to execute an agreement upon request, valid under
the law of the jurisdiction in which such agreement is executed, and in a form
acceptable to Administrator, Parent or their Affiliates and their counsel,
committing themselves to maintain the Group's Confidential and Proprietary
Information in strict confidence and not to disclose it to any unauthorized
person or entity. Upon termination of this Agreement for any reason, the

this Agreement for any reason whatsoever, or at any time upon the request of the
Group, the Administrator, Parent and their Affiliates will promptly deliver or
cause to be delivered to the Group all documents, data and other information in
their possession that contain any Group's Confidential and Proprietary
Information. The Administrator, Parent and their Affiliates shall not take or
retain any documents or other information, or any reproduction or excerpt
thereof, containing any Group's Confidential and Proprietary Information, unless
otherwise authorized in writing by the Group. In the event of termination of
this Agreement, Administrator, Parent and their Affiliates will deliver to the
Group all documents and data pertaining to Group's Confidential and Proprietary
Information not otherwise purchased as part of the Acquisition.

         (e) Group's Obligations Regarding Proprietary Interest.

                  (i) Acknowledgement of Proprietary Interest. The Group
recognizes the proprietary interest of the Administrator, Parent and their
Affiliates in any Confidential and Proprietary Information (as hereinafter
defined). The Group acknowledges and agrees that any and all Confidential and
Proprietary Information of Administrator, Parent or their Affiliates
("Administrators's Confidential and Proprietary Information") communicated to,
learned of, developed or otherwise acquired by the Group during the term of this
Agreement shall be the property of Administrator, Parent or their Affiliates.
The Group further acknowledges and understands that its disclosure of
Administrator's Confidential and Proprietary Information will result in
irreparable injury and damage to Administrator, Parent or their Affiliates. As
used herein, "Confidential and Proprietary Information" means all trade secrets
and other confidential


                                       28

and/or proprietary information of the Administrator, Parent or their Affiliates,
including information derived from reports, investigations, research, work in
progress, codes, marketing and sales programs, financial projections, cost
summaries, pricing formula, contract analyses, financial information,
projections, confidential filings with any state or federal agency, and all
other confidential concepts, methods of doing business, ideas, materials or
information (other than the Group's patient records) prepared or performed for,
by or on behalf of the parties hereto by its employees, officers, directors,
agents, representatives, or consultants. Confidential and Proprietary
Information shall not include any information which: (i) was known to the
parties hereto prior to its disclosure by the Administrator, Parent or their
Affiliate; (ii) is or becomes publicly known through no wrongful act of the
Group or any of its employees; (iii) is disclosed pursuant to a statute,
regulation or the order of a court of competent jurisdiction, provided that the
Group provides prior notice to Administrator, Parent or its Affiliates.

                  (ii) Covenant Not-to-Divulge Confidential and Proprietary
Information. The Group acknowledges and agrees that Administrator, Parent or
their Affiliates are entitled to prevent the disclosure of Confidential and
Proprietary Information. The Group agrees at all times during the term of this
Agreement and thereafter to hold in strictest confidence and not to disclose to
any person, firm or corporation, except as may be necessary for the discharge of
its obligations under this Agreement, and not to use, except in the pursuit of
the business of the Practice, Administrator's Confidential and Proprietary
Information, without the prior written consent of Administrator, Parent and
their Affiliates; unless (i) such information becomes known or available to the
public generally through no wrongful act of the Group or its employees or (ii)
disclosure is required by law or the rule, regulation or order of any
governmental authority under color of law; provided, that prior to disclosing
any Administrator's Confidential and Proprietary Information pursuant to this
clause (iii), the Group shall, if possible, give prior written notice thereof to
Administrator, Parent and their Affiliates and provide such parties with the
opportunity to contest such disclosure. The Group shall take all necessary and
proper precautions against disclosure of any Administrator's Confidential and
Proprietary Information to unauthorized persons by any of its officers,
directors, employees or agents. All officers, directors, employees, and agents
of the Group who will have access to all or any part of the Administrator's
Confidential and Proprietary Information will be required to execute an
agreement upon request, valid under the law of the jurisdiction in which such
agreement is executed, and in a form acceptable to Administrator, Parent and
their Affiliates and its counsel, committing themselves to maintain the
Administrator's Confidential and Proprietary Information in strict confidence
and not to disclose it to any unauthorized person or entity. Upon termination of
this Agreement for any reason, the Group and their employees shall cease all use
of any of the Administrator's Confidential and Proprietary Information and shall
execute such documents as may be reasonably necessary to evidence their
abandonment of any claim thereto.

                  (iii) Return of Materials. In the event of any termination of
this Agreement for any reason whatsoever, or at any time upon the request of
Administrator, Parent or their Affiliates, the Group will promptly deliver or
cause to be delivered to Administrator, Parent and their Affiliates all
documents, data and other information in their possession that contains any
Administrator's Confidential and Proprietary Information regarding
Administrator, Parent and their Affiliates. The Group shall not take or retain
any documents or other information, or any


                                       29
<PAGE>   35
reproduction or excerpt thereof, containing any Administrator's Confidential and
Proprietary Information, unless otherwise authorized in writing by the party
possessing such Administrator's Confidential and Proprietary Information. In the
event of termination of this Agreement, the Group will deliver to Administrator,
Parent and their Affiliates all documents and data pertaining to Administrator's
Confidential and Proprietary Information of the other parties not otherwise
purchased as part of the Purchased Assets.

         (f) Third Party Beneficiaries. The members of the APPI Group not party
to this Agreement are hereby specifically made third party beneficiaries of this
Section 6.1, with the power to enforce the provisions hereof.

         Section 6.2 Restrictive Covenants. The Group shall obtain and enforce
formal agreements with each Physician Employee who is either (i) a Group
Physician Stockholder or (ii), to the extent permitted under applicable law, a
Full-time Physician Employee which each contain certain restrictive covenants
thereof pertaining to covenants not to compete and/or solicit with and not to
divulge the Confidential and Proprietary Information of any member of the APPI
Group or the Practice (the "Restrictive Covenants"). Except as otherwise
approved by the Joint Planning Board, each Group Physician Stockholder or
Full-time Physician Employee shall agree, during the term of his/her employment
or contractor agreement with the Practice and for a period of twenty-four (24)
months after any termination of such agreement: (i) not to establish, operate or
provide professional radiology services at any office, practice, hospital or
health care facility providing services substantially similar to those provided
by the Practice pursuant to this Agreement within 15 miles of any location of
any Practice Site(s) and (ii) to be bound by non-solicitation, noncompetition
and nondisclosure of confidential/proprietary information and engagement of
Administrator covenants similar to those applicable to the Group as contained in
Section 6.1 hereof. Except as otherwise approved by the Joint Planning Board,
each Group Physician Stockholder or Full-time Physician Employee shall agree
that during the term of his/her employment or contractor agreement with the
Group (w) not to practice radiological medicine other than at the Premises or
such other location or Practice Site(s) as approved by the Joint Planning Board;
(x) to devote substantially all of his or her professional time, effort and
ability to the Practice; (y) to request in writing and receive in writing prior
approval from the Joint Planning Board to engage in any outside medical
activities; and (z) to turn over to the Practice, to be included in Professional
Revenues attributed to the Practice, any income derived by such Group Physician
Stockholder or Full-time Physician Employee from any outside medical activity or
related source from the following medically-related activities: teaching,
consulting, medical research, inventions developed utilizing the Group's or the
Practice's time and material, testimony for litigation, and insurance
examinations. The Group shall not materially amend, alter or otherwise change
any term or provision of any Stockholder Employment Agreement or Physician
Employee Employment Agreement relating to the foregoing covenants in this
Section 6.2 without the prior written consent of Administrator; notwithstanding
the foregoing, any such amendment, alteration or change shall not be
inconsistent with the terms or provisions of this Agreement. Following
termination of this Agreement, the Group shall not amend, alter or otherwise
change any term or provision of the Restrictive Covenants, unless such
provisions are no longer in force and effect pursuant to the terms of the
applicable Stockholder Employment Agreement or Physician Employee Employment
Agreement at the time of termination of this


                                       30
<PAGE>   36
Agreement. In the event the Purchase Assets are acquired by the Group pursuant
to Article X, the obligation of the Group to enforce Restrictive Covenants shall
be limited to enforcement of non-solicitation and nondisclosure of
confidential/proprietary information covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Stockholder Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Stockholder Employment
Agreements and, to the extent permitted under applicable law, the Physician
Employee Employment Agreements, upon the request of Administrator, the Group
shall assign to Administrator such causes of action and/or other rights it has
related to such breach or default and shall cooperate with and provide
reasonable assistance to Administrator with respect thereto; in which case, all
costs and expenses incurred in connection therewith shall be borne by
Administrator and shall be included in Administrator Expenses, and Administrator
shall be entitled to all damages and other amounts recovered thereby. In the
event the Purchase Assets are acquired by the Group pursuant to Article X, the
obligation of the Group to enforce Restrictive Covenants shall be limited to
enforcement of non-solicitation and nondisclosure of confidential/proprietary
information covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period, scope of activity restricted
and/or the geographical area applicable to such provision of the Restrictive
Covenants or this Article VI. The invalidity or non-enforceability of any
provision of the Restrictive Covenants or this Article VI in any respect shall
not affect the validity or enforceability of the remainder of the Restrictive
Covenants or this Article VI or of any other provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Stockholder or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Stockholder or Full-time


                                       31
<PAGE>   37
Physician Employee from the restrictive covenants contained in Section 6.2,
above. In the event the Group elects to release such Group Physician Stockholder
or Full-time Physician Employee, the Group hereby covenants that it shall obtain
a formal agreement between each Group Physician Stockholder or Full-time
Physician Employee, as the case may be, and Administrator which provides that,
for a period of two (2) years following termination of any employment agreement
with the Group, such Group Physician Stockholder or Full-time Physician Employee
agrees to (a) engage Administrator as the sole and exclusive manager and
administrator of the non-medical functions and services of said Group Physician
Stockholder's or Full-time Physician Employee's medical practice and (b) pay to
Administrator the identical amount [NY only] of revenues paid by the Group to
the Administrator attributable to such Group Physician Stockholder or Full-time
Physician Employee derived from such Group Physician Stockholder's or Full-time
Physician Employee's performance of professional medical services within 15
miles of any Practice Site.

         Section 6.6 Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary
information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and work effort
required and (y) the Group shall not be required to employ any Radiologist
previously associated with such Professional Service Opportunity.

         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half


                                       32
<PAGE>   38
of the time during which the Administrator, Parent or their Affiliates must
respond to an offer described in the Administrator's Notice, the Group shall
deliver to Administrator a written notice stating whether or not the Group
elects to accept or reject the New Professional Service Opportunity which
election shall be binding on the Group. If the Group does not elect to exercise
the right or fails to provide the notice to Administrator within the time frame
herein provided, Administrator shall be released from the right of first offer
with respect to that particular New Professional Service Opportunity. Prior to
consummating any asset acquisition, merger or other consolidation of any
Radiologist, group of Radiologists, or professional corporation or association
(or other professional entity) whose owners are Radiologists within any
Secondary Service Area, Administrator shall first consult with the Joint
Planning Board.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service Opportunity as contemplated in 
subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

             "New Professional Service Opportunity" shall mean a Professional
Service Opportunity pursuant to which the Group or any other member of an APPI
Group managed by Parent, Administrator or their Affiliates is not currently
providing professional Radiology services.

             "Primary Service Area" shall mean that area within a five (5) mile
radius from any imaging center owned, operated or managed by Administrator,
Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.

             "Professional Service Opportunity" shall mean any opportunity to
perform professional Radiology services for any hospital, hospital system or
imaging center under a formal agreement with such entity.

             "Radiologist" shall mean and include both radiologists and

                                       33
<PAGE>   39
             "Secondary Service Area" shall mean (i) during the 12-month period
following the Acquisition Effective Date, that area which extends ten (10) miles
beyond the boundary of any Primary Service Area and (ii) during the remaining
term of this Agreement, that area which extends five (5) miles beyond the
boundary of any Primary Service Area.

         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.


                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on
Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on


                                       34
<PAGE>   40
the 15th day following the end of such month (or the first preceding day that is
a business day if the 15th day is not a business day) (a "Payment Date"). Except
as otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates
based upon available information for such month, and adjustments to the
estimated payments shall be made to reconcile final amounts due under Section
7.1 on the next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee and to other related provisions of
this Agreement shall be a joint decision of the parties, shall be memorialized
in a written amendment to this Agreement, and shall be based upon the
methodology used to generally determine Services Fees hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses


                                       35
<PAGE>   41
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

         (a)      payment of all accrued Practice Expenses for the prior month
                  (subject to the proviso in the preceding sentence);

         (b)      payment of the accrued Service Fee for the prior month;

         (c)      payment of the outstanding balance of all amounts advanced to
                  the Group through the end of the prior month, and applicable
                  interest thereon (as contemplated in Section 7.3); and

         (d)      payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited in the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).


                                  ARTICLE VIII

                                     Records

         Section 8.1 Records. All records relating in any way to the operation
of the Practice (other than Group Records) shall, subject to the obligations of
the Practice to maintain patient medical records pursuant to Section 3.2(g), at
all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter, the
Group or its agents shall have reasonable access during normal business hours to
the Group's and Administrator's personnel and financial records relating to the
Practice, including, but not limited to, records of collections, expenses and
disbursements as kept by Administrator in performing Administrator's obligations
under this Agreement, and the Group may copy any or all such records.


                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1 Insurance to be Maintained by the Group.


                                       36
<PAGE>   42
         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.

         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.


                                       37
<PAGE>   43
         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5 Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,

liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its shareholders, employees
and/or subcontractors (other than Administrator, Parent, Affiliates or their

Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
the Group's indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,

                              Term and Termination

         Section 10.1 Term of Agreement. This Agreement shall commence on the
date hereof and shall expire on the 40th anniversary hereof unless earlier
terminated pursuant to the terms of either Section 10.3 or Section 10.4 or
automatically extended pursuant to the terms of Section 10.2.

         Section 10.2 Extended Term. Unless earlier terminated as provided for
in either Section 10.3 or Section 10.4, the term of this Agreement shall be
automatically extended for additional terms of five (5) years each, unless
either party delivers to the other party, not less than twelve (12) months nor
earlier than fifteen (15) months prior to the expiration of the preceding term,
written notice of such party's intention not to extend the term of this
Agreement.

         Section 10.3 Termination by the Group. The Group may, in its sole
discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not the
obligation, to cure any Material Adminstrator Default. Notwithstanding anything
to the contrary in this Agreement, following receipt by Administrator of the
notice of a Material Administrator Default and until such Material Administrator
Default shall be cured, the Group may take such action as may be reasonably
required to cover such Material Administrator Default so as to maintain for the
Group the same level of service as before the Material Administrator Default,
without prejudicing in any way the Group's other rights and remedies, and may
offset all of its costs from the amounts which may otherwise be due to
Administrator under this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that
individual from participating in or from receiving reimbursement under any
program funded by the federal government or by any state government,
notwithstanding any available post-sanction remedies, or (4) is otherwise
disciplined by any licensing, regulatory or professional entity or institution,
the result of any of which event does or is reasonably expected to materially
adversely affect the Practice, the result of any of which event described in
subparagraphs (1) through (4) above, in the absence of termination of a
Physician Employee or a Physician Extender Employee or other action of the Group
to monitor and cure such act or conduct by such employee, does or reasonably
would be expected to materially and adversely affect the Practice or the Group.
Notwithstanding anything to the contrary in this Agreement, following


                                       40
<PAGE>   46
receipt by the Group of the notice of a Material Group Default, and until such
Material Group Default shall be cured, the Administrator may take such action as
may be reasonably required to cover such Material Group Default so as to
maintain for the Administrator the same level of service at the Premises as
before the Material Group Default, without prejudicing in any way Administrator
other rights and remedies, and may offset all of its costs of cover from amounts
which may otherwise due to the Group under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Stockholders and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee [or Physician Extender Employee] that intends to
retire prior to expiration of such five-year period, then such Physician
Employee or Physician Extender Employee shall not be counted for purposes of
determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         (b) Upon the expiration of this Agreement pursuant to Sections 10.1 or
10.2.

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator and/or Parent, the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or their
Affiliates, as the case may be, pursuant to subparagraph


                                       41
<PAGE>   47
(c) below, all assets, tangible or intangible real or personal, of
Administrator, Parent or their Affiliates that relate primarily to the Practice
other than Administrator's, Parent's or their Affiliates' accounting and
financial records (the "Purchase Assets"), including, but not limited to,
without duplication, (i) all equipment, furniture, fixtures, furnishings,
inventory, supplies, improvements, additions and leasehold improvements utilized
by the Practice, (ii) any real estate owned by Administrator, Parent or
Affiliates that is occupied by or used primarily for the benefit of the
Practice, (iii) all unamortized intangible assets (including, without
limitation, goodwill) set forth on the financial statements of Administrator,
Parent or their Affiliates used solely in connection with the Practice or
otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and its Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c) Purchase Price. The Purchase Price shall be the lesser of (i) Fair
Market Value of the Purchase Assets subject to the assumption of the Practice
Related Liabilities or (ii) the value of the Actual Consideration (defined
below)(alternatively, the "Purchase Price"); provided, however, the Purchase
Price shall not be less than the net book value of the Purchase Assets at the
Termination Date. The Purchase Price shall be paid pursuant to Section 10.7. For
purposes of this subparagraph (c), the term "Actual Consideration" shall mean
(i) cash consideration paid to the Group pursuant to the Acquisition Agreement
and (2) an amount equal to the number of shares of Parent Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, reorganizations,
or any similar transaction whereby the Parent Common Stock is increased or
decreased or exchanged for a different number or kind of securities) issued
pursuant to the Acquisition Agreement multiplied by the fair market value of
Parent Common Stock immediately prior to the time that a Termination Notice is
provided pursuant to Section 10.7. The Purchase Price shall be appropriately
adjusted to offset and account for any monetary obligations of the Group or
Administrator owing to the other as provided herein.

         (d) Exercise of Option.

                  (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                  (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and


                                       42
<PAGE>   48
assume the Practice Related Liabilities pursuant to this Section 10.6 (i) during
the five-year period following the Acquisition Effective Date if this Agreement
is terminated pursuant to Sections 10.3(c), 10.4(b) or 10.4(c) and (ii) at any
time in the event of a termination pursuant to Section 10.4(a).

         (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at the Purchase Closing, Administrator and/or their Affiliates, as the
case may be, shall transfer and assign the Purchase Assets to the Group, and in
consideration therefor, the Group shall (a) pay to Administrator, Parent and/or
their Affiliates an amount in cash or, at the option of the Group (subject to
the conditions set forth below), Parent Common Stock (valued pursuant to Section
10.6(c) hereof), or some combination of cash and Parent Common Stock equal to
the Purchase Price and (b) assume the Practice Related Liabilities. The
structure of the transaction set forth in this Section 10.7 shall, if possible,
be structured as a tax-free transaction under applicable law. Each party shall
execute such documents or instruments as are reasonably necessary, in the
opinion of each party and its counsel, to effect the foregoing transaction. The
Group shall, and shall use its best efforts to cause each shareholder of the
Group to, execute such documents or instruments as may be necessary to cause the
Group to assume the Practice Related Liabilities and to release Administrator,
Parent and/or their Affiliates, as the case may be, from any liability or
obligation with respect thereto. In the event the Group desires to pay all or a
portion of the Purchase Price in shares of Parent Common Stock, such transaction
shall be subject to the satisfaction of each of the following conditions:

         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims, proxies, options, stockholders' agreements
and encumbrances (not including any applicable securities restrictions and
lock-up arrangements with the Parent or any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain


                                       43
<PAGE>   49
financing for such acquisition but is unable to obtain such financing and (iii)
there is either a Material Administrator Default pursuant to Section 10.3(a) or
(c) or a Material Group Default pursuant to Section 10.4(b) triggering a sale of
the Purchase Assets, the Group shall be entitled to obtain financing from
Administrator, Parent and/or their Affiliates but only for the difference
between the Fair Market Value of the Purchase Assets and the net book value of
the Purchase Assets. The terms of such financing shall be for a five (5) year
period at an interest rate equal to the prime rate (as published in the Wall
Street Journal) plus four percent (4%) or such lesser rate as is required to be
in conformance with all applicable state and federal law. In the event the Group
is entitled to obtain financing from Administrator, Parent and/or their
Affiliates the Group shall execute and deliver to Administrator, Parent and/or
their Affiliates all such documentation necessary and appropriate to effectuate
the financing transaction including, without limitation, a secured promissory
note, security agreement and financing statements and such documentation shall
contain such representations, warranties and conditions customary to a secured
transaction of this size.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator, Parent and/or their Affiliates to the
Group or the Group to the Administrator, Parent and/or their Affiliates
(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

         (a) Administrator, Parent and/or their Affiliates shall use their best
efforts to cooperate with the Group for the appropriate transfer of management
services.

         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.


                                       44
<PAGE>   50
         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.


                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

         Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means set forth in Section 11.1 and prior to commencing
an arbitration procedure pursuant to this Article XI, the parties shall meet to
discuss and consider other alternative dispute resolution procedures other than
arbitration, provided, however that if the parties hereto agree to an
alternative to arbitration they may agree to an alternative set of rules,
including rules of evidence and procedure. If at any time prior to the rendering
of the decision by the arbitrator (or pursuant to such other alternative dispute
resolution procedure) as contemplated in this Article XI to the extent a party
makes a written offer to the other party proposing a settlement of the matter(s)
at issue and such offer is rejected, then the party rejecting such offer shall
be obligated to pay the costs and expenses (excluding the amount of the award
granted under the decision) of the party that offered the settlement from the
date such offer was received by such other party if the decision is for a dollar
amount that is less than the amount of such offer to settle. Notwithstanding the
foregoing, the terms and provisions of this Article XI shall not preclude any


                                       45
<PAGE>   51
party hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

         Section 11.3 Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among Administrator and the Group arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within 30 days of notice
by a party to the other of its desire to seek arbitration under this Article XI
one arbitrator mutually acceptable to Administrator and the Group to hear and
decide all such claims under this Article XI. If such matter or action involves
health-care issues, then the arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators proposed shall be impartial
and independent of all parties. If the parties cannot agree on the selection of
an arbitrator within said 30-day period, then any party may in writing request
the judge of the United States District Court for the Northern District of
California senior in term of service to appoint the arbitrator and, subject to
this Article XI, such arbitrator shall hear all arbitration matters arising
under this Article XI.

         Section 11.4 Applicable Rules.

         (a) Each arbitration hearing shall be held at a place in _____________
acceptable to the arbitrator. The arbitration shall be conducted in accordance
with the Commercial Arbitration Rules of the American Arbitration Association to
the extent such rules do not conflict with the terms hereof. The decision of the
arbitrator shall be reduced to writing and shall be binding on the parties and
such decision shall contain a concise statement of the reasons in support of
such decision. Judgment upon the award(s) rendered by the arbitrator may be
entered and execution had in any court of competent jurisdiction or application
may be made to such court for a judicial acceptance of the award and an order of
enforcement. The charges and expenses of the arbitrator shall be shared equally
by the parties to the hearing.

         (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI. In
fulfilling his duties with respect to determining the amount of any loss, the
arbitrator may consider such matters as, in the opinion of the arbitrator, are
necessary or helpful to make a proper valuation. The arbitrator may consult with
and engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

         (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.


                                       46
<PAGE>   52
         (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e) All privileges under California and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying California law.


                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment.

         (a) Administrator shall have the right to assign its rights hereunder
to Parent or any direct or indirect wholly-owned subsidiary of Administrator or
Parent (that remains a wholly-owned subsidiary of Administrator or Parent) or to
a financial institution as collateral security for the indebtedness of Parent,
Administrator or their Affiliates without the consent of the Group. No
assignment under subsection (a) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         (b) Administrator, Parent and their Affiliates shall provide notice to
the Group of Administrator's intent (i) to assign this Agreement (other than as
permitted in Section 12.1(a) herein), (ii) sell all or substantially all of the
assets of Administrator or (iii) effectuate a consolidation, merger or sale of a
majority of the capital stock of Administrator as soon as practicable following
a decision by the Parent's and Administrator's respective boards of directors to
seek such assignment or sale. The assignment of this Agreement (other than as
permitted in Section 12.1(a)), the sale of all or substantially all of the
assets of Administrator by Parent or a consolidation, merger or sale of a
majority of the capital stock of Administrator shall not be permitted unless
Administrator shall give written notice to the Group stating the party who made
the offer and specifying the purchase price offered (the "Notice"). The Group
shall have the option to repurchase the Purchase Assets on the same terms and
conditions set forth in the Notice. In the event the Group fails to provide
written notice to Administrator of its intent to exercise its option to
repurchase the Purchase Assets pursuant to this Section 12.1 within the earlier
of (i) thirty (30) days or (ii) one-half of the time during which Administrator,
Parent or their Affiliates must respond to an offer following the Group's
receipt of the Notice, the option contained in this Section 12.1 shall be deemed
null and void and of no further force and effect, and Administrator shall be
free to assign the Agreement, sell all or substantially all of the assets of
Administrator or sell or transfer all of the capital stock Administrator without
the consent of the Group. No assignment under this subsection (b) shall relieve
Administrator or Parent of their obligations hereunder without the consent of
the Group.

         Section 12.3 Waiver of Provisions. Any waiver of any terms and

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group

this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)

or court to constitute the practice of medicine, the performance of said act or
service by Administrator shall be deemed waived and forever unenforceable and
the provisions of this Section 12.6 shall be applicable. Neither party shall
claim or assert illegality as a defense to the enforcement of this Agreement or
any provision hereof; instead, any such purported illegality shall be resolved
pursuant to the terms of this Section 12.6 and Section 12.9.

         Section 12.7 Parties In Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto. Except
as provided in Section 6.1(g), neither this Agreement nor any other agreement

subject matter hereof, and

<PAGE>   54
supersede all prior agreements and understandings, both written and oral, among
the parties, or any of them, with respect to the subject matter hereof.

         Section 12.9 Severability. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 12.10 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULE GOVERNING

         Section 12.11 No Waiver; Remedies Cumulative. No party hereto shall by
any act (except by written instrument pursuant to Section 12.3 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default in or breach of any of the terms
and conditions hereof. No failure to exercise, nor any delay in exercising, on
the part of any party hereto,. any right, power or privilege hereunder shall
operate as a waiver thereof. No single or partial exercise of any right, power
or privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. No remedy set forth in this
Agreement or otherwise conferred upon or reserved to any party shall be
considered exclusive of any other remedy available to any party, but the same
shall be distinct, separate and cumulative and may be exercised from time to
time as often as occasion may arise or as may be deemed expedient.

         Section 12.12 Communications. The Group and Administrator, Parent and
their Affiliates agree that good communication between the parties is essential

this Agreement. Nothing contained in this subsection (b)(i) shall be construed
to limit the Group's ability to provide notice of a Material Administrator
Default pursuant to Section 10.3(b) of this Agreement.

                  (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service
is construed or deemed to constitute the practice of medicine, Administrator
shall deliver to the Group notice of such an event. The Group shall be entitled
to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

         Section 3.2   General Administrative Services.

         (a) Exclusive Management Services; Scope of Services. Except as
provided in Exhibit 3.2(a), the Group hereby engages Administrator to serve as
its exclusive manager and administrator of non-medical business services
relating to the operation of the Practice, subject to matters reserved for the
Group or referred to the Joint Planning Board as herein contemplated, and
Administrator shall have all necessary authority and hereby agrees to perform
such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

         (b)      Billing and Collection.

                  (i) Administrator shall, in the name of and on behalf of the
Group, bill patients, insurance companies, Managed Care Payors, and other
third-party payors and collect all fees for services rendered in connection with
the Practice at the Premises or any Practice Site(s) (including all fees
generated by both the Technical Operations and the Professional Operations), for
services performed outside the Practice for its hospitalized patients, and for
all other professional and Practice services. The Group hereby appoints
Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:

                                       10
<PAGE>   16

                         (A) to bill patients, insurance companies, Managed Care
Payors, and other third-party payors in the Group's name and on its behalf;

                         (B) to collect accounts receivable resulting from such
billing not otherwise purchased by Administrator (as provided for in Section
3.2(e) hereof) in the Group's name and on its behalf;

                         (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                         (D) to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                         (E) to take possession of and endorse in the name of
the Group and deposit into the Deposit Account (and/or in the name of an
individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                         (F) upon the prior consent of the Group, which consent
shall not be unreasonably withheld or delayed, to initiate the institution of
legal proceedings in the name of the Group or a Physician Employee to collect
any accounts and monies owed to the Group or the Physician Employee, to enforce
the rights of the Group or the Physician Employee, as the case may be, as
creditor under any contract or in connection with the rendering of any service,
and to contest adjustments and denials by governmental agencies (or their fiscal
intermediaries) as third-party payors.

                  (ii) The Group hereby appoints Administrator as its true and
lawful attorney-in-fact to deposit into the Deposit Account all Professional
Revenues and Technical Revenues collected by Administrator as provided for in
this Section 3.2(b). The Group covenants, and shall cause all Physician
Employees and Physician Extender Employees to covenant, to forward any payments
received with respect to any Professional Revenues or Technical Revenues
generated for services provided by the Group or any of its Physician Employees
and Physician Extender Employees to Administrator for deposit. Administrator
shall have the right to withdraw funds from the Deposit Account and all owners
of the Deposit Account shall execute a revocable standing transfer order (the
"Transfer Order") under which the bank maintaining the Deposit Account shall
periodically transfer the entire balance of the Deposit Account to a separate
bank account owned solely by Administrator (the "Administrator Account"). The
Group and Administrator hereby agree to execute from time to time such documents
and instructions as shall be required by the bank maintaining the Deposit
Account and mutually agreed upon to effectuate the foregoing provisions and to
extend or amend such documents and instructions. Any action by the Group that
materially interferes with the operation of this Section, including but not
limited to, any failure to deposit or to have Administrator deposit any


                                       11
<PAGE>   17

Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit Account not authorized by the express
terms of this Agreement or any other written agreement executed by each of the
parties, or any revocation of or attempt to revoke the Transfer Order (otherwise
than upon expiration or termination of this Agreement), will constitute a breach
of this Agreement and will entitle Administrator, in addition to any other
remedies it may have at law or in equity, to seek a court ordered assignment of
the rights provided to Administrator pursuant to subparagraph (i) above.

                  (iii) All monies shall be accounted for by Administrator as
being distinctly attributable to the Group. The Group may perform the functions
or exercise the rights set forth in this Section 3.2(b) only with the prior
written consent of Administrator. The Group shall execute such documents in form
and substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c) Accounting. Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of
the Practice, and Administrator shall perform all bookkeeping and accounting
services necessary or appropriate for the efficient operation of the Practice,
including the maintenance, custody and supervision of business records, ledgers
and reports; the establishment, administration and implementation of accounting
procedures, controls and systems; and implementation and management of
computer-based management information systems. The Group and its authorized
representatives shall have the right to review all financial books and records
maintained by Administrator relating to the operation of the Practice and to the
cash management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the parties have
agreed herein. The purchase price shall be an amount equal to the aggregate face
amount of the accounts receivable being sold less contractual adjustments and


                                       12
<PAGE>   18

estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

         (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication
services and medical transcribing services; provided, however, that the Group
may elect to prepare its own Tax Returns, in which case, the cost of preparing
such Tax Returns in excess of $2,500 per annum shall be included in Excluded
Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group
containing a balance sheet, income statement and monthly operational reports
which detail payments, charges and accounts receivable statistics, monthly
reconciliation reports on cash management and any other financial reports
reasonably requested by a member of the Joint Planning Board designated by the
Group, which shall be delivered to the Group as soon as practicable, but no
later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

         (g)      Records and Files.

                  (i) Administrator's Business and Financial Records. At all
times during and after the term of this Agreement, including any extensions or
renewals hereof, all business records, including but not limited to, business
agreements, books of account, personnel records, general administrative records
and all information generated under or contained in the management information
system pertaining to Administrator's obligations hereunder, and other business
information of Administrator of any kind or nature, except for patient medical
records and the Group's Records (as defined in subparagraph (ii) below), shall
be and remain the sole property of Administrator; provided that during and after
termination of this Agreement, the Group shall be entitled to reasonable access
to such records and information, including the right to obtain copies thereof in
any media reasonably requested by the Group, for any purpose related to patient
care or the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years. Administrator hereby agrees
to preserve the confidentiality of such patient medical records and to use the
information in such records only for the limited purposes necessary to perform
management services and, within the limits of its responsibilities hereunder, to
ensure that provision is made for appropriate care for patients of the Practice.


                                       13
<PAGE>   19

                  (ii) The Practice's Business and Financial Records. At all
times during and after the term of this Agreement, the business agreements,
financial, operational, corporate and personnel records and information relating
exclusively to the business and activities of the Group and patient medical
records and charts (hereinafter referred to as the "Group's Records") shall be
and remain the sole property of the Group.

                  (iii) Access to Records. At all times during and after the
term of this Agreement, each party and its authorized agents shall be entitled,
upon request and with reasonable advance notice, to obtain access (within not
more than 30 days following receipt of such notice by the other party or
parties) to all records of the other party directly related to the performance
of such party's obligations pursuant to this Agreement; provided, however, that
such right shall not allow for access to patient, medical and other records that
must be kept confidential as required by law. Either party, at its expense,
shall have the right to make copies in any media of any records to which it has
access pursuant to this subparagraph (iii).

                  (iv) Compliance with Law. The management of all files and
records by Administrator and the Group shall comply with all applicable federal,
state and local statutes and regulations.

         (h) Collections. Subject to the consent requirement contained in
Section 3.2(b)(i)(F), Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees and
pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

         Section 3.3   Facilities.

         (a) Premises. Administrator shall make available to the Group the
Premises that are described in Exhibit 3.3(a) attached hereto and such other
improvements made by Administrator or Parent for the use of the Group hereunder.

waste. Administrator shall maintain the Premises in good condition and make or
cause to be made all necessary repairs thereto.

         (b) Personal Property. Administrator shall provide the Group with the
use of the equipment, furniture, fixtures, furnishings and other personal
property acquired in the Acquisition or any replacements thereto, together with

property necessary or appropriate for the efficient operation of the Practice
acquired by Administrator or Parent (subject to review and approval of the Joint

(collectively, the "Personal Property"). Administrator shall maintain the
Personal Property in good condition and make or cause to be made all necessary
repairs thereto.

                                       14
<PAGE>   20

         (c) Expenses. All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the
Premises and the Personal Property, including, without limitation, all
reasonably necessary costs of repairs, maintenance and improvements, utility
expenses (i.e., telephone, electric, gas and water), janitorial services, refuse
disposal, real or personal property lease cost payments and expenses, interest,
refinancing expenses, depreciation, loss on disposition of assets, taxes and
casualty, liability and other insurance, shall be included in Practice Expenses.
To the extent the Premises or Personal Property are used in connection with the
Professional Operations, the costs and expenses associated with such usage shall
be allocated between Professional Expenses and Technical Expenses as approved by
the Joint Planning Board.

         (d) Disposition. Subject to provisions contained in existing agreements
to which Administrator or Parent is or becomes a party and, where necessary and
appropriate for the efficient operation of the Practice, nothing herein shall be
construed as precluding Administrator or Parent from selling, leasing or
otherwise disposing of all or any part of the Premises, Personal Property, real
property, improvements, trade names, trademarks and other intangible property;
provided, however, any such sale, lease or disposition shall be subject to the
prior review and approval of the Joint Planning Board and shall not eliminate or
diminish Administrator's obligations hereunder.

         (e) No Warranties or Representations. The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

         Section 3.4   Acquisition and Assistance.

         (a) Employment of Physicians. Subject to consultation with the Joint
Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice. Subject to
consultation with the Joint Planning Board, in the event that a decision is made
by the Group to pursue the employment of selected physicians, if requested by
the Group, Administrator will provide recruiting, consulting, negotiating and
other advisory services in connection with such transaction. Notwithstanding the
preceding, as set forth in and subject to the provisions of Section 4.1 hereof,
the Group shall have complete control of and responsibility for the hiring of
all Physician Employees and Physician Extender Employees.

         (b) Acquisitions. In the event that the Group contemplates acquiring or
affiliating with a physician group, practice or other entity, and such
acquisition or affiliation involves the use or expenditure of Administrator's
and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a
result of such an acquisition or affiliation including, without limitation,
capital and personnel (collectively, the "Resources"), then the Group shall
first consult with the Joint Planning Board and Administrator, and any decision
to make such affiliation or acquisition shall

                                       15
<PAGE>   21

be subject to prior approval of Administrator, which decision of the
Administrator shall be provided to the Group in a reasonable and timely manner
following satisfactory review of the physician group, practice or other entity
to be acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto. If such contemplated acquisition or affiliation does not
involve the use or expenditure of any of Administrator's and/or Parent's
Resources, then such decision shall be in the sole discretion of the Group.
Notwithstanding any provision contained herein to the contrary, any person or
entity with which the Group affiliates or acquires shall be subject to the terms
and conditions of this Agreement. If a decision is made to proceed with any
affiliation or acquisition of a physician group or practice, the Group may seek
from Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

         Section 3.5   Financial Planning and Budgeting.

         (a) Budgeting. Administrator shall collaborate with the Group and the
Joint Planning Board in the preparation of all annual capital and operating
budgets. These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors. For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board. The
projected annual operating budget for each subsequent year shall be subject to
the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice. For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

         (b) Capital Expenditures. Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

                  (i) Budgeted Expenditures. All budgeted capital expenditures
and improvement projects shall be subject to final review and approval by the
Joint Planning Board prior to the making of any actual expenditure. Such review
and approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.

                  (ii) Non-Budgeted Expenditures. Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared by
the Joint Planning Board in consultation with the Group and Administrator. All
requests for non-budgeted capital


                                       16
<PAGE>   22

expenditures and improvements at or for the benefit of the Practice in excess of
either $75,000 individually or an aggregate amount equivalent to $2,500
multiplied by the number of Full-time Physician Employees employed at the time
the capital budget for such Group for the applicable year is determined
(provided, however, that such aggregate amount shall not exceed $250,000 for any
calendar year) must be approved by the Board of Directors of Parent or by any
committee specifically designated by the Board of Directors of Parent for such
purposes.

         (c) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such Personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors"). Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning Board,
be the responsibility of the Group. Notwithstanding the preceding language, if a
contract or relationship between any Managed Care Payor and the Group involves
or affects a contract or relationship with any other physician group or practice
serviced or managed by Administrator,


                                       17
<PAGE>   23

Parent or any of their Affiliates (the "Other Practices") and a consensus among
the Group and the Other Practices cannot be reached regarding the contract or
relationship, then the ultimate decision as to the approval, disapproval,
termination or amendment of such contract or relationship involving the Group,
the Other Practices and such Managed Care Payor shall be determined by the
affirmative vote of the Physician Board Members (as defined below) who hold a
majority of the Group Voting Power (as defined below). For purposes of this
Section 3.7, (i) the term "Physician Board Members" shall mean (a) those members
appointed by the Group who serve on the Joint Planning Board and (b) those
persons appointed by the Other Practices who serve on the Other Practices' joint
boards (in a similar capacity to the Joint Planning Board) as part of their
contractual relationship with Parent, Administrator or any of their Affiliates,
and (ii) the term "Group Voting Power" shall mean the total voting percentage
which may be cast by the Physician Board Members on a collective basis, with the
percentage of votes able to be cast by any Group or Other Practice, as
applicable, shall be equal to the quotient determined by dividing (x) the total
estimated annual professional revenues to be generated by the Group from such
Managed Care Contract as determined by Administrator, Parent or their
Affiliates, as appropriate, in its sole discretion, by (y) the total estimated
annual professional revenues to be generated by the Group and all Other
Practices from such Managed Care Contract as determined by the Administrator,
Parent or their Affiliates, as appropriate, in its sole discretion.

         Section 3.8 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.9 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or
advertising programs, in which case, a pro rata share of such costs will be
included in Practice Expenses as determined by the Joint Planning Board. The
parties hereto agree that all public relations and advertising programs shall be
conducted in compliance with applicable standards of medical ethics, laws and
regulations.

         Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program
shall be included in Administrator Expenses;


                                       18
<PAGE>   24

provided, however, that any expenses related to such program that are incurred
for services provided solely for the direct benefit of the Practice shall be
included in Practice Expenses.

         Section 3.11 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by
the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,
development of long-term business objectives and other related matters.

         Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.


                                   ARTICLE IV

                            Obligations of the Group

Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender
Employees, and other employees who may have malpractice exposure or liability,
are insurable and by participating in an ongoing risk management program.

         Section 4.2 Professional Services. The Group shall provide
professional services to its patients in compliance at all times with ethical
standards, laws, rules and regulations applicable to the operations of the
Practice, the Physician Employees and Physician Extender

Employees. The Group shall ensure that each Physician Employee and each
Physician Extender Employee has all required licenses, credentials, approvals or
other certifications to perform his or her duties and services for the Practice
and, in the event that the Group becomes aware of any disciplinary actions or
medical malpractice actions initiated against any Physician Employee or
Physician Extender Employee, the Group shall promptly inform Administrator of
such action and the underlying facts and circumstances. If required by
applicable law, any state or federal regulatory agency or any contractual
obligations, the Group shall carry out a program to monitor the quality of
medical care practiced at the Practice; provided, however, that the preceding
language shall not limit the Group's obligation to participate in or comply with
any programs established by Administrator or Parent for purposes of ensuring
that the Group complies with applicable law. The Group shall employ Physician
Employees and Physician Extender Employees as is necessary to provide efficient
medical care to patients of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery
items on prepaid Managed Care Contracts which are authorized and permitted by
such contracts. A copy of such agreements and any amendment thereto shall be
provided to Administrator for review no later than thirty (30) days prior to the
proposed effective date thereof.

         Section 4.4 Group's Internal Matters. The Group shall be responsible
for matters involving its governance, employees and similar internal matters,
including, but not limited to, preparation and contents of such reports to
regulatory authorities governing the Group that the Group is required by law to
provide, distribution of professional fee income among the Group Physician
Members, disposition of the Group's property and membership interests (subject
to any restrictions contained herein), hiring and firing of its employees,
licensing and implementing all compliance plans and procedures as described in
Section 4.6. Except for the expenses attributable to the distribution of
professional fee income among the Group Physician Members,

         Section 4.5 Name. Administrator agrees that the Group shall be entitled

         Section 4.6 Compliance with Laws. The Group shall, and shall use its
best efforts to cause the Physician Employees, Physician Extender Employees and

local laws, rules, regulations and restrictions in the conduct of the Practice's
business. Without limiting the generality of the foregoing, the Group shall
comply and shall cause each Physician Employee, Physician Extender Employee and
other employee of the Group to comply, with all laws applicable to the operation
of the Practice in the generation, transportation, treatment, storage, disposal
or other handling of radioactive, medical, biological or hazardous materials or

furnishing or arranging for the furnishing of any item or service for which
payment may be made in whole or in part by Medicare or Medicaid, or (ii) in
return for purchasing, leasing, or ordering, or arranging for or recommending
purchasing, leasing, or

         Section 5.1 Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy is counted;
provided, however, that no proxy shall be valid after the expiration of eleven
(11) months from the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2 Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

         (a) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and

based upon economic feasibility, productivity and then current market conditions
in light of both the particular project and the Group as a whole.

         (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess
of five percent (5%) to the annual capital or operating budgets.

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

         (d) Patient Fees. As a part of the annual operating budget, in
consultation with and upon recommendation of the Joint Planning Board, the Group
shall review and adopt the fee schedule for all professional services rendered
by the Practice.

         (e) Ancillary Services and Fees. The Joint Planning Board shall approve
Practice-provided non-medical ancillary services (including, without limitation,
fees for technical services which do not generate Professional Revenues) based
upon the pricing, access to, and quality of such services and shall review and
adopt the fee schedule for all ancillary services.

         (f) Provider and Payor Relationships. Subject to Section 3.7, decisions
regarding the establishment or maintenance of relationships with institutional
health care providers and payors shall be approved by the Group after
consultation with the Joint Planning Board.

         (g) Strategic Planning. The Joint Planning Board shall develop a plan

time. Such plan will, among other things, identify opportunities, objectives,
and the resources required to effect such plan.

         (h) Capital Expenditures. The Joint Planning Board shall determine the
priority of capital expenditures in accordance with Section 3.5(b) hereof.

         (i) Provider Hiring. The Joint Planning Board shall consult with the
Group to recommend the number and type of Physician Employees and Physician
Extender Employees required for the efficient operation of the Practice.

         (j) Non-Physician Personnel. The Joint Planning Board shall consult
with Administrator to recommend the number and type of non-physician employees
required for the efficient operation of the Practice.

         Section 5.3 Acts of the Joint Planning Board. Except as otherwise
specifically provided herein, the act of the members holding a majority of the
voting power of the Joint Planning Board shall be the act of the Joint Planning
Board. The Group agrees that, unless the

<PAGE>   30

following are approved in advance by the Joint Planning Board and such act of
the Joint Planning Board includes the approval by both of the members designated
by Administrator, it shall take no action or implement any decision that would
(i) require Administrator to expend funds or incur obligations beyond those set
forth under Sections 3.5 or 5.2 of this Agreement; (ii) have a material adverse
effect on the amount of Administrator's management fee under Article VII; or
(iii) otherwise have a material adverse effect on Administrator's financial
interests under this Agreement. Except as provided in the prior sentence, the
Group and Administrator hereby agree to be bound by the act of the Joint
Planning Board if such act was approved by the members holding at least a
majority of the voting power of the Joint Planning Board. No action of the Joint
Planning Board shall be effective unless authorized by the members holding a
majority of the voting power of the Joint Planning Board present or represented
by proxy at the applicable meeting. In the event that a matter cannot be
resolved by the Joint Planning Board due to a tie vote, and no compromise can be
reached, then either (x) the Board of Directors of Parent or (y) a committee
designated by the Board of Directors of Parent containing at least one (1)
physician member will make a final determination on the matter in dispute
provided that both the Group and Administrator shall have had an opportunity to
make a presentation to the Board of Directors of Parent or a committee thereof,
as applicable. A quorum of the Joint Planning Board shall consist of the members
holding a majority of the voting power of the Joint Planning Board, present in
person, by telephone, or by proxy and the quorum must remain for the duration of
the meeting.

         Section 5.4 Joint Planning Board Meetings. Meetings of the Joint
Planning Board may be held by telephone or similar communication equipment so

may be called by fifty percent (50%) of the votes.

         (c) Notice Requirement. A member calling a special meeting must provide
all other members with ten (10) days' advance written or telephonic notice.
Notice must be given or sent to the member's address or telephone number as
shown on the records of the Joint Planning Board. Notice may be delivered
directly to each member or to a person at the member's principal place of
business who would reasonably be expected to communicate that notice promptly to
the member.

         (d)  Waiver of Notice Requirement.

              (i) Written Waiver, Consent or Approval. Notice of a special
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the


                                       25
<PAGE>   31

special meeting. Such waiver, consent or approval need not specify the purpose
of the special meeting. All such waivers, consents, and approvals shall be filed
with the Joint Planning Board records or made a part of the minutes of the
special meetings.

                  (ii) Failure to Object. Notice of special meeting need not be
given to any member who attends the special meeting and does not protest before
or at the commencement of the special meeting such lack of notice.

and not to disclose it to any unauthorized person or entity. Upon termination of
this Agreement for any reason, the Group and their employees shall cease all use
of any of the Administrator's Confidential and Proprietary Information and shall
execute such documents as may be reasonably necessary to evidence their
abandonment of any claim thereto.

                  (iii) Return of Materials. In the event of any termination of
this Agreement for any reason whatsoever, or at any time upon the request of
Administrator, Parent or their Affiliates, the Group will promptly deliver or
cause to be delivered to Administrator, Parent and their Affiliates all
documents, data and other information in their possession that contains any
Administrator's Confidential and Proprietary Information regarding
Administrator, Parent and their Affiliates. The Group shall not take or retain
any documents or other information, or any


                                       29
<PAGE>   35

reproduction or excerpt thereof, containing any Administrator's Confidential and
Proprietary Information, unless otherwise authorized in writing by the party
possessing such Administrator's Confidential and Proprietary Information. In the
event of termination of this Agreement, the Group will deliver to Administrator,
Parent and their Affiliates all documents and data pertaining to Administrator's
Confidential and Proprietary Information of the other parties not otherwise
purchased as part of the Purchased Assets.

         (f) Third Party Beneficiaries. The members of the APPI Group not party
to this Agreement are hereby specifically made third party beneficiaries of this
Section 6.1, with the power to enforce the provisions hereof.

         Section 6.2 Restrictive Covenants. The Group shall obtain and enforce
formal agreements with each Physician Employee who is either (i) a Group
Physician Stockholder or (ii), to the extent permitted under applicable law, a
Full-time Physician Employee which each contain certain restrictive covenants
thereof pertaining to covenants not to compete and/or solicit with and not to
divulge the Confidential and Proprietary Information of any member of the APPI
Group or the Practice (the "Restrictive Covenants"). Except as otherwise
approved by the Joint Planning Board, each Group Physician Member or Full-time
Physician Employee shall agree, during the term of his/her employment or
contractor agreement with the Practice and for a period of twenty-four (24)
months after any termination of such agreement: (i) not to establish, operate or
provide professional radiology services at any office, practice, hospital or
health care facility providing services substantially similar to those provided
by the Practice pursuant to this Agreement within 15 miles of any location of
any Practice Site(s) and (ii) to be bound by non- solicitation, noncompetition
and nondisclosure of confidential/proprietary information and engagement of
Administrator covenants similar to those applicable to the Group as contained in
Section 6.1 hereof. Except as otherwise approved by the Joint Planning Board,
each Group Physician Member or Full-time Physician Employee shall agree that
during the term of his/her employment or contractor agreement with the Group (w)
not to practice radiological medicine other than at the Premises or such other
location or Practice Site(s) as approved by the Joint Planning Board; (x) to
devote substantially all of his or her professional time, effort and ability to
the Practice; (y) to request in writing and receive in writing prior approval
from the Joint Planning Board to engage in any outside medical activities; and
(z) to turn over to the Practice, to be included in Professional Revenues
attributed to the Practice, any income derived by such Group Physician Member or
Full-time Physician Employee from any outside medical activity or related source
from the following medically-related activities: teaching, consulting, medical
research, inventions developed utilizing the Group's or the Practice's time and
material, testimony for litigation, and insurance examinations. The Group shall
not materially amend, alter or otherwise change any term or provision of any
Member Employment Agreement or Physician Employee Employment Agreement relating
to the foregoing covenants in this Section 6.2 without the prior written consent
of Administrator; notwithstanding the foregoing, any such amendment, alteration
or change shall not be inconsistent with the terms or provisions of this
Agreement. Following termination of this Agreement, the Group shall not amend,
alter or otherwise change any term or provision of the Restrictive Covenants,
unless such provisions are no longer in force and effect pursuant to the terms
of the applicable Member Employment Agreement or Physician Employee Employment
Agreement at the time of termination of this


                                       30
<PAGE>   36

Agreement. In the event the Purchase Assets are acquired by the Group pursuant
to Article X, the obligation of the Group to enforce Restrictive Covenants shall
be limited to enforcement of non-solicitation and nondisclosure of
confidential/proprietary information covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Member Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Member Employment Agreements
and, to the extent permitted under applicable law, the Physician Employee
Employment Agreements, upon the request of Administrator, the Group shall assign
to Administrator such causes of action and/or other rights it has related to
such breach or default and shall cooperate with and provide reasonable
assistance to Administrator with respect thereto; in which case, all costs and
expenses incurred in connection therewith shall be borne by Administrator and
shall be included in Administrator Expenses, and Administrator shall be entitled
to all damages and other amounts recovered thereby. In the event the Purchase
Assets are acquired by the Group pursuant to Article X, the obligation of the
Group to enforce Restrictive Covenants shall be limited to enforcement of
non-solicitation and nondisclosure of confidential/proprietary information
covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period, scope of activity restricted
and/or the geographical area applicable to such provision of the Restrictive
Covenants or this Article VI. The invalidity or non-enforceability of any
provision of the Restrictive Covenants or this Article VI in any respect shall
not affect the validity or enforceability of the remainder of the Restrictive
Covenants or this Article VI or of any other provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Member or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Member or Full-time Physician Employee


                                       31
<PAGE>   37

from the restrictive covenants contained in Section 6.2, above. In the event the
Group elects to release such Group Physician Stockholder or Full-time Physician
Employee, the Group hereby covenants that it shall obtain a formal agreement
between each Group Physician Member or Full- time Physician Employee, as the
case may be, and Administrator which provides that, for a period of two (2)
years following termination of any employment agreement with the Group, such
Group Physician Member or Full-time Physician Employee agrees to (a) engage
Administrator as the sole and exclusive manager and administrator of the
non-medical functions and services of said Group Physician Member's or Full-time
Physician Employee's medical practice and (b) pay to Administrator the identical
amount [NY only] of revenues paid by the Group to the Administrator attributable
to such Group Physician Member or Full-time Physician Employee derived from such
Group Physician Member's or Full-time Physician Employee's performance of
professional medical services within 15 miles of any Practice Site.

         Section 6.6 Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary
information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and work effort
required and (y) the Group shall not be required to employ any Radiologist
previously associated with such Professional Service Opportunity.

         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half of the time during which the
Administrator, Parent or their Affiliates must respond to an offer

                                       32
<PAGE>   38

described in the Administrator's Notice, the Group shall deliver to
Administrator a written notice stating whether or not the Group elects to accept
or reject the New Professional Service Opportunity which election shall be
binding on the Group. If the Group does not elect to exercise the right or fails
to provide the notice to Administrator within the time frame herein provided,
Administrator shall be released from the right of first offer with respect to
that particular New Professional Service Opportunity. Prior to consummating any
asset acquisition, merger or other consolidation of any Radiologist, group of
Radiologists, or professional corporation or association (or other professional
entity) whose owners are Radiologists within any Secondary Service Area,
Administrator shall first consult with the Joint Planning Board.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service Opportunity as contemplated in 
subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

                  "New Professional Service Opportunity" shall mean a
Professional Service Opportunity pursuant to which the Group or any other member
of an APPI Group managed by Parent, Administrator or their Affiliates is not
currently providing professional Radiology services.

                  "Primary Service Area" shall mean that area within a five (5)
mile radius from any imaging center owned, operated or managed by Administrator,
Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.

                  "Professional Service Opportunity" shall mean any opportunity
to perform professional Radiology services for any hospital, hospital system or
imaging center under a formal agreement with such entity.

                  "Radiologist" shall mean and include both radiologists and
radiation oncologists.

                  "Radiology" shall mean and include diagnostic imaging,
interventional radiology and radiation oncology services.

                  "Secondary Service Area" shall mean (i) during the 12-month
period following the Acquisition Effective Date, that area which extends ten
(10) miles beyond the boundary of


                                       33
<PAGE>   39

any Primary Service Area and (ii) during the remaining term of this Agreement,
that area which extends five (5) miles beyond the boundary of any Primary
Service Area.

         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.


                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on
Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on


                                       34
<PAGE>   40

Exhibit 7.1, such amounts paid shall be estimates based upon available
information for such month, and adjustments to the estimated payments shall be
made to reconcile final amounts due under Section 7.1 on the next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee and to other related provisions of
this Agreement shall be a joint decision of the parties, shall be memorialized
in a written amendment to this Agreement, and shall be based upon the
methodology used to generally determine Services Fees hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the


                                       35
<PAGE>   41

Group shall not be responsible for such amount. In performing its obligations
pursuant to Article III, on the fifteenth (15th) day following the end of each
calendar month, Administrator shall apply an amount equal to the aggregate face
amount of the prior month's accounts receivables, less contractual adjustments
and estimated allowances for bad debt as determined in accordance with Section
3.2(e), in the following order of priority:

          (a) payment of all accrued Practice Expenses for the prior month
             (subject to the proviso in the preceding sentence);
     
          (b) payment of the accrued Service Fee for the prior month;

          (c) payment of the outstanding balance of all amounts advanced to the
              Group through the end of the prior month, and applicable interest
              thereon (as contemplated in Section 7.3); and

          (d) payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).


                                  ARTICLE VIII

                                     Records

         Section 8.1 Records. All records relating in any way to the operation
of the Practice (other than Group Records) shall, subject to the obligations of
the Practice to maintain patient medical records pursuant to Section 3.2(g), at
all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter, the
Group or its agents shall have reasonable access during normal business hours to
the Group's and Administrator's personnel and financial records relating to the
Practice, including, but not limited to, records of collections, expenses and
disbursements as kept by Administrator in performing Administrator's obligations
under this Agreement, and the Group may copy any or all such records.


                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1  Insurance to be Maintained by the Group.

                                       36
<PAGE>   42

         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in excess of the limits of such policies
identified in subsections (i) and (ii) hereof shall be included in Administrator
Expenses.

         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.

                                       37
<PAGE>   43

         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5 Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other
than such persons who are also officers, directors, shareholders, employees,
agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its members, employees and/or
subcontractors (other than Administrator, Parent, Affiliates or their employees,
officers, directors, agents, attorneys and consultants) during the term of this
Agreement. Provided, however, that in the event an indemnification obligation
under the preceding sentence arises as of the result of any act or omission of a
person who is an officer, member or other equity holder, director, employee,
agent, attorney or consultant of Administrator, Parent or any of their
Affiliates (other than in connection with the activities of the Joint Planning
Board), such person shall not be entitled to indemnification in connection
therewith and any other adjustment as is equitable shall be made to the Group's
indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers, members,
directors, employees, agents, attorneys and consultants, harmless from and
against any and all liabilities, losses, damages, claims, causes of action and
expenses (including reasonable attorneys' fees), not covered by insurance
(including self-insured insurance and reserves), whenever arising or incurred,
that are caused or asserted to have been caused, directly or indirectly, by or
as a result of the performance of any intentional acts, negligent acts or
omissions by Administrator, Parent or Affiliates and/or any of their respective
shareholders, employees and/or subcontractors (other than the Group or its
employees) during the term of this Agreement. Provided, however that in the
event an indemnification obligation under the preceding sentence arises as a
result of any act or omission of a person who is an officer, member or other
equity holder, director, employee, agent, attorney or consultant of the Group
(other than in connection with the activities of the Joint Planning Board), such
person shall not be entitled to indemnification in connection therewith and any
other adjustment as is equitable shall be made to Administrator's or Parent's
indemnification obligation arising thereby.

terminated pursuant to the terms of either Section 10.3 or Section 10.4 or

         Section 10.2 Extended Term. Unless earlier terminated as provided for

following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate this Agreement, if and only if, such termination shall have been
approved by the affirmative vote of the holders of two-thirds of the interests
of the equity holders of the Group. The Group agrees that the financial
institution contemplated in Section 12.1(a) shall have the right, but not the
obligation, to cure any Material Adminstrator Default. Notwithstanding anything
to the contrary in this Agreement, following receipt by Administrator of the
notice of a Material Administrator Default and until such Material Administrator
Default shall be cured, the Group may take such action as may be reasonably
required to cover such Material Administrator Default so as to maintain for the
Group the same level of service as before the Material Administrator Default,
without prejudicing in any way the Group's other rights and remedies, and may
offset all of its costs from the amounts which may otherwise be due to
Administrator under this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in

to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license to practice medicine reasonably would be expected
to be subject to revocation or suspension, whether or not actually revoked or
suspended, or (3) is notified in writing of any adverse action by any state or
federal department or agency that has the effect of either excluding that
individual from participating in or from receiving reimbursement under any
program funded by the federal government or by any state government,
notwithstanding any available post-sanction remedies, or (4) is otherwise
disciplined by any licensing, regulatory or professional entity or institution,
the result of any of which event does or is reasonably expected to materially
adversely affect the Practice, the result of any of which event described in
subparagraphs (1) through (4) above, in the absence of termination of a
Physician Employee or a Physician Extender Employee or other action of the Group
to monitor and cure such act or conduct by such employee, does or reasonably
would be expected to materially and adversely affect the Practice or the Group.
Notwithstanding anything to the contrary in this Agreement, following


                                       40
<PAGE>   46

receipt by the Group of the notice of a Material Group Default, and until such
Material Group Default shall be cured, the Administrator may take such action as
may be reasonably required to cover such Material Group Default so as to
maintain for the Administrator the same level of service at the Premises as
before the Material Group Default, without prejudicing in any way Administrator
other rights and remedies, and may offset all of its costs of cover from amounts
which may otherwise due to the Group under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Members and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee [or Physician Extender Employee] that intends to
retire prior to expiration of such five-year period, then such Physician
Employee or Physician Extender Employee shall not be counted for purposes of
determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or

         (b) Upon the expiration of this Agreement pursuant to Sections 10.1 or
10.2.

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator and/or Parent, the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or their
Affiliates, as the case may be, pursuant to subparagraph


                                       41
<PAGE>   47

(c) below, all assets, tangible or intangible real or personal, of
Administrator, Parent or their Affiliates that relate primarily to the Practice
other than Administrator's, Parent's or their Affiliates' accounting and
financial records (the "Purchase Assets"), including, but not limited to,
without duplication, (i) all equipment, furniture, fixtures, furnishings,
inventory, supplies, improvements, additions and leasehold improvements utilized
by the Practice, (ii) any real estate owned by Administrator, Parent or
Affiliates that is occupied by or used primarily for the benefit of the
Practice, (iii) all unamortized intangible assets (including, without
limitation, goodwill) set forth on the financial statements of Administrator,
Parent or their Affiliates used solely in connection with the Practice or
otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and its Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c) Purchase Price. The Purchase Price shall be the lesser of (i) Fair
Market Value of the Purchase Assets subject to the assumption of the Practice
Related Liabilities or (ii) the value of the Actual Consideration (defined
below)(alternatively, the "Purchase Price"); provided, however, the Purchase
Price shall not be less than the net book value of the Purchase Assets at the
Termination Date. The Purchase Price shall be paid pursuant to Section 10.7. For
purposes of this subparagraph (c), the term "Actual Consideration" shall mean
(i) cash consideration paid to the Group pursuant to the Acquisition Agreement
and (2) an amount equal to the number of shares of Parent Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, reorganizations,
or any similar transaction whereby the Parent Common Stock is increased or
decreased or exchanged for a different number or kind of securities) issued
pursuant to the Acquisition Agreement multiplied by the fair market value of
Parent Common Stock immediately prior to the time that a Termination Notice is
provided pursuant to Section 10.7. The Purchase Price shall be appropriately
adjusted to offset and account for any monetary obligations of the Group or
Administrator owing to the other as provided herein.

         (d) Exercise of Option.

             (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

             (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and


                                       42
<PAGE>   48

assume the Practice Related Liabilities pursuant to this Section 10.6 (i) during
the five-year period following the Acquisition Effective Date if this Agreement
is terminated pursuant to Sections 10.3(c), 10.4(b) or 10.4(c) and (ii) at any
time in the event of a termination pursuant to Section 10.4(a).

         (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at the Purchase Closing, Administrator and/or its Affiliates, as the case
may be, shall transfer and assign the Purchase Assets to the Group, and in
consideration therefor, the Group shall (a) pay to Administrator, Parent and/or
their Affiliates an amount in cash or, at the option of the Group (subject to
the conditions set forth below), Parent Common Stock (valued pursuant to Section
10.6(c) hereof), or some combination of cash and Parent Common Stock equal to
the Purchase Price and (b) assume the Practice Related Liabilities. The
structure of the transaction set forth in this Section 10.7 shall, if possible,
be structured as a tax-free transaction under applicable law. Each party shall
execute such documents or instruments as are reasonably necessary, in the
opinion of each party and its counsel, to effect the foregoing transaction. The
Group shall, and shall use its best efforts to cause each shareholder of the
Group to, execute such documents or instruments as may be necessary to cause the
Group to assume the Practice Related Liabilities and to release Administrator,
Parent and/or their Affiliates, as the case may be, from any liability or
obligation with respect thereto. In the event the Group desires to pay all or a
portion of the Purchase Price in shares of Parent Common Stock, such transaction
shall be subject to the satisfaction of each of the following conditions:

         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims, proxies, options, stockholders' agreements
and encumbrances (not including any applicable securities restrictions and
lock-up arrangements with the Parent or any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain


                                       43
<PAGE>   49

financing for such acquisition but is unable to obtain such financing and (iii)
there is either a Material Administrator Default pursuant to Section 10.3(a) or
(c) or a Material Group Default pursuant to Section 10.4(b) triggering a sale of
the Purchase Assets, the Group shall be entitled to obtain financing from
Administrator, Parent and/or their Affiliates, but only for the difference
between the Fair Market Value of the Purchase Assets and the net book value of
the Purchase Assets. The terms of such financing shall be for a five (5) year
period at an interest rate equal to the prime rate (as published in the Wall
Street Journal) plus four percent (4%) or such lesser rate as is required to be
in conformance with all applicable state and federal law. In the event the Group
is entitled to obtain financing from Administrator, Parent and/or their
Affiliates, the Group shall execute and deliver to Administrator, Parent and/or
their Affiliates all such documentation necessary and appropriate to effectuate
the financing transaction including, without limitation, a secured promissory
note, security agreement and financing statements and such documentation shall
contain such representations, warranties and conditions customary to a secured
transaction of this size.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator, Parent and/or their Affiliates to the
Group or the Group to the Administrator, Parent and/or their Affiliates
(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

         (a) Administrator, Parent and/or their Affiliates shall use their best
efforts to cooperate with the Group for the appropriate transfer of management
services.

         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.


                                       44
<PAGE>   50

         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.


                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

         Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means set forth in Section 11.1 and prior to commencing
an arbitration procedure pursuant to this Article XI, the parties shall meet to
discuss and consider other alternative dispute resolution procedures other than
arbitration, provided, however that if the parties hereto agree to an
alternative to arbitration they may agree to an alternative set of rules,
including rules of evidence and procedure. If at any time prior to the rendering
of the decision by the arbitrator (or pursuant to such other alternative dispute
resolution procedure) as contemplated in this Article XI to the extent a party
makes a written offer to the other party proposing a settlement of the matter(s)
at issue and such offer is rejected, then the party rejecting such offer shall
be obligated to pay the costs and expenses (excluding the amount of the award
granted under the decision) of the party that offered the settlement from the
date such offer was received by such other party if the decision is for a dollar
amount that is less than the amount of such offer to settle. Notwithstanding the
foregoing, the terms and provisions of this Article XI shall not preclude any


                                       45
<PAGE>   51

party hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

         Section 11.3 Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among Administrator and the Group arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within 30 days of notice
by a party to the other of its desire to seek arbitration under this Article XI
one arbitrator mutually acceptable to Administrator and the Group to hear and
decide all such claims under this Article XI. If such matter or action involves
health-care issues, then the arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators proposed shall be impartial
and independent of all parties. If the parties cannot agree on the selection of
an arbitrator within said 30-day period, then any party may in writing request
the judge of the United States District Court for the _____________ District of
__________ senior in term of service to appoint the arbitrator and, subject to
this Article XI, such arbitrator shall hear all arbitration matters arising
under this Article XI.

         Section 11.4 Applicable Rules.

         (a) Each arbitration hearing shall be held at a place in _____________
acceptable to the arbitrator. The arbitration shall be conducted in accordance
with the Commercial Arbitration Rules of the American Arbitration Association to
the extent such rules do not conflict with the terms hereof. The decision of the
arbitrator shall be reduced to writing and shall be binding on the parties and
such decision shall contain a concise statement of the reasons in support of
such decision. Judgment upon the award(s) rendered by the arbitrator may be
entered and execution had in any court of competent jurisdiction or application
may be made to such court for a judicial acceptance of the award and an order of
enforcement. The charges and expenses of the arbitrator shall be shared equally
by the parties to the hearing.

         (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI. In
fulfilling his duties with respect to determining the amount of any loss, the
arbitrator may consider such matters as, in the opinion of the arbitrator, are
necessary or helpful to make a proper valuation. The arbitrator may consult with
and engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

         (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.

                                       46
<PAGE>   52

         (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e) All privileges under Kansas and federal law, including
attorney-client and work- product privileges, shall be preserved and protected
to the same extent that such privileges would be protected in a federal court
proceeding applying Kansas law.


                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment.

         (a) Administrator shall have the right to assign its rights hereunder
to Parent or any direct or indirect wholly-owned subsidiary of Administrator or
Parent (that remains a wholly-owned subsidiary of Administrator or Parent) or to
a financial institution as collateral security for the indebtedness of Parent,
Administrator or their Affiliates without the consent of the Group. No
assignment under subsection (a) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         (b) Administrator, Parent and their Affiliates shall provide notice to
the Group of Administrator's intent (i) to assign this Agreement (other than as
permitted in Section 12.1(a) herein), (ii) sell all or substantially all of the
assets of Administrator or (iii) effectuate a consolidation, merger or sale of a
majority of the capital stock of Administrator as soon as practicable following
a decision by the Parent's and Administrator's respective boards of directors to
seek such assignment or sale. The assignment of this Agreement (other than as
permitted in Section 12.1(a)), the sale of all or substantially all of the
assets of Administrator by Parent or a consolidation, merger or sale of a
majority of the capital stock of Administrator shall not be permitted unless
Administrator shall give written notice to the Group stating the party who made
the offer and specifying the purchase price offered (the "Notice"). The Group
shall have the option to repurchase the Purchase Assets on the same terms and
conditions set forth in the Notice. In the event the Group fails to provide
written notice to Administrator of its intent to exercise its option to
repurchase the Purchase Assets pursuant to this Section 12.1 within the earlier
of (i) thirty (30) days or (ii) one-half of the time during which Administrator,
Parent or their Affiliates must respond to an offer following the Group's
receipt of the Notice, the option contained in this Section 12.1 shall be deemed
null and void and of no further force and effect, and Administrator shall be
free to assign the Agreement, sell all or substantially all of the assets of
Administrator or sell or transfer all of the capital stock Administrator without
the consent of the Group. No assignment under this subsection (b) shall relieve
Administrator or Parent of their obligations hereunder without the consent of
the Group.

<PAGE>   53

         Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

         Section 12.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 12.4 Additional Documents. Each of the parties hereto agrees to
execute any document or documents that may be reasonably requested from time to
time by the other party to implement or complete such party's obligations
pursuant to this Agreement.

         Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,
costs and expenses including, but not limited to, attorney's fees, costs and
expenses for trial, appellate proceedings and negotiations, in addition to any
other relief granted.

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group
and Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this
Agreement should be construed or deemed, by any governmental authority, agency
or court to constitute the practice of medicine, the performance of said act or
service by Administrator shall be deemed waived and forever unenforceable and
the provisions of this Section 12.6 shall be applicable. Neither party shall
claim or assert illegality as a defense to the enforcement of this Agreement or
any provision hereof; instead, any such purported illegality shall be resolved
pursuant to the terms of this Section 12.6 and Section 12.9.

         Section 12.7 Parties In Interest; No Third Party Beneficiaries. Except

and that nothing herein shall be construed as the practice of medicine by
Administrator or Parent. To the extent any act or service required of
Administrator is construed or deemed to constitute the practice of medicine,
Administrator is released from any obligation to provide, and the Group shall be
deemed not to have requested Administrator to provide, such act or service
without otherwise affecting the other terms of this Agreement.

         Section 2.3 No Payment or Other Compensation for Referrals. The parties
hereby agree that the benefits to the Group hereunder do not require, are not
payment or compensation in cash or in kind for, and are not in any way
contingent upon the admission, referral or any other arrangement for the
provision of any item or service offered by Administrator or any of its
Affiliates to any of the Group's patients in any facility controlled, managed or
operated by Administrator.

         Section 2.4 Group's Internal Matters. The Group shall be solely
responsible for matters involving its corporate governance, employees and
similar internal matters, including, but not limited to, preparation and
contents of such reports to regulatory authorities governing the Professional
Operations that the Group is required by law to provide, and distribution of
salaries and professional fee income among the Group Physician Stockholders,
Physician Employees and Physician Extender Employees. Administrator shall assist
the Group, where necessary and appropriate, by providing the information and
data to be included in such reports.


                                   ARTICLE III

                    Services to be Provided by Administrator

         Section 3.1 General.

         (a) Scope of Services Provided. Administrator shall provide or arrange
for the services set forth in this Article III, and the costs, fees, expenses
and other disbursements incurred by Administrator or Parent in connection
therewith shall be included in Practice Expenses, except to the extent such
costs, fees or expenses are expressly included in Excluded Practice Expenses or
Administrator Expenses. Administrator is authorized to perform its services
hereunder as is necessary or appropriate for the efficient operation of the
Practice, including, without limitation, performance of some of the business
office functions at locations other than the Practice. Except to the extent
necessary to comply with applicable laws, regulations or professional ethical
standards, the Group will not act in a manner which would prevent Administrator
from performing its duties hereunder and will provide such information and
assistance to Administrator as is reasonably required by Administrator to
perform its services hereunder. Administrator shall cause its employees, to
comply with all applicable federal, state and local laws, rules and regulations
in Administrator's provision of services hereunder.

         (b) Alternative Management Arrangements.

                  (i) If Administrator fails to perform, provide or arrange for
the services set forth in this Article III in a manner reasonably consistent
with commercially available services offered by third party providers of
physician practice management services of the type and scope offered by
Administrator, then the Group shall provide written notice of such event to
Administrator, Parent or their Affiliates, including reasonable evidence of such
commercially available services. Administrator shall deliver to the Group within
thirty (30) days after receipt


                                       9
<PAGE>   15
by Administrator of such written notice a written plan detailing the methods and
procedures Administrator, Parent or their Affiliates shall utilize to restore
the level of service contemplated by this Agreement. In the event Administrator
fails to restore the level of service contemplated by this Agreement in
accordance with such plan submitted or in any event within ninety (90) days, the
Group shall be entitled to reimbursement by Administrator for the reasonable
costs and expenses of obtaining such service on a temporary basis until such
time Administrator demonstrates its ability to perform such service at the level
contemplated by this Agreement. Nothing contained in this subsection (b)(i)
shall be construed to limit the Group's ability to provide notice of a Material
Administrator Default pursuant to Section 10.3(b) of this Agreement.

                  (ii) If Administrator is unable to perform or is released from
performing any service which is required of Administrator because such service
is construed or deemed to constitute the practice of medicine, Administrator
shall deliver to the Group notice of such an event. The Group shall be entitled
to reimbursement by Administrator for the reasonable costs and expenses of
obtaining such services until such time Administrator is able to perform or
provide such service in accordance with applicable law.

         Section 3.2 General Administrative Services.

         (a) Exclusive Management Services; Scope of Services. Except as
provided in Exhibit 3.2(a), the Group hereby engages Administrator to serve as
its exclusive manager and administrator of non-medical business services
relating to the operation of the Practice, subject to matters reserved for the
Group or referred to the Joint Planning Board as herein contemplated, and
Administrator shall have all necessary authority and hereby agrees to perform
such services. The Group agrees that the purpose and intent of this Agreement is
to relieve the Group to the maximum extent possible of the administrative,
accounting, purchasing, non-physician personnel and other non-medical business
aspects of the Practice. Administrator agrees that the Group, Physician
Employees and Physician Extender Employees, and only the Group, Physician
Employees and Physician Extender Employees, will perform the professional
medical functions of the Practice. Administrator shall have no authority,
directly or indirectly, to perform, and shall not perform, any professional
medical function. Administrator may, however, advise the Group as to the
relationship between the Group's performance of professional medical functions
and the overall administrative and business functions of the Practice to the
extent permitted by applicable law.

         (b) Billing and Collection.

                  (i) Administrator shall, in the name of and on behalf of the
Group, bill patients, insurance companies, Managed Care Payors, and other
third-party payors and collect all fees for services rendered in connection with
the Practice at the Premises or any Practice Site(s) (including all fees
generated by both the Technical Operations and the Professional Operations), for
services performed outside the Practice for its hospitalized patients, and for
all other professional and Practice services. The Group hereby appoints
Administrator for the term of this Agreement to be its true and lawful
attorney-in-fact, for the following purposes:



                                       10
<PAGE>   16
                           (A) to bill patients, insurance companies, Managed
Care Payors, and other third-party payors in the Group's name and on its behalf;

                           (B) to collect accounts receivable resulting from
such billing not otherwise purchased by Administrator (as provided for in
Section 3.2(e) hereof) in the Group's name and on its behalf;

                           (C) to receive payments on behalf of the Group from
insurance companies, prepayments received from health care plans, Medicare,
Medicaid, Managed Care Payors and all other third-party payors;

                           (D) to ensure the collection and receipt in
Administrator's name and for Administrator's account of all accounts receivable
of the Practice purchased by Administrator, and to deposit such collections in
the Account;

                           (E) to take possession of and endorse in the name of
the Group and deposit into the Deposit Account (and/or in the name of an
individual physician, such payment intended for purpose of payment of
professional fees related to the Practice) any notes, checks, money orders,
insurance payments and other instruments received in payment of accounts
receivable not otherwise purchased by Administrator; and

                           (F) upon the prior consent of the Group, which
consent shall not be unreasonably withheld or delayed, to initiate the
institution of legal proceedings in the name of the Group or a Physician
Employee to collect any accounts and monies owed to the Group or the Physician
Employee, to enforce the rights of the Group or the Physician Employee, as the
case may be, as creditor under any contract or in connection with the rendering
of any service, and to contest adjustments and denials by governmental agencies
(or their fiscal intermediaries) as third-party payors.

                  (ii) The Group hereby appoints Administrator as its true and
lawful attorney-in-fact to deposit into the Deposit Account all Professional
Revenues and Technical Revenues collected by Administrator as provided for in
this Section 3.2(b). The Group covenants, and shall cause all Physician
Employees and Physician Extender Employees to covenant, to forward any payments
received with respect to any Professional Revenues or Technical Revenues
generated for services provided by the Group or any of its Physician Employees
and Physician Extender Employees to Administrator for deposit. Administrator
shall have the right to withdraw funds from the Deposit Account and all owners
of the Deposit Account shall execute a revocable standing transfer order (the
"Transfer Order") under which the bank maintaining the Deposit Account shall
periodically transfer the entire balance of the Deposit Account to a separate
bank account owned solely by Administrator (the "Administrator Account"). The
Group and Administrator hereby agree to execute from time to time such documents
and instructions as shall be required by the bank maintaining the Deposit
Account and mutually agreed upon to effectuate the foregoing provisions and to
extend or amend such documents and instructions. Any action by the Group that
materially interferes with the operation of this Section, including but not
limited to, any failure to deposit or to have Administrator deposit any


                                       11
<PAGE>   17
Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit Account not authorized by the express
terms of this Agreement or any other written agreement executed by each of the
parties, or any revocation of or attempt to revoke the Transfer Order (otherwise
than upon expiration or termination of this Agreement), will constitute a breach
of this Agreement and will entitle Administrator, in addition to any other
remedies it may have at law or in equity, to seek a court ordered assignment of
the rights provided to Administrator pursuant to subparagraph (i) above.

                  (iii) All monies shall be accounted for by Administrator as
being distinctly attributable to the Group. The Group may perform the functions
or exercise the rights set forth in this Section 3.2(b) only with the prior
written consent of Administrator. The Group shall execute such documents in form
and substance as approved by Administrator and its legal counsel to permit
Administrator to exercise the rights and powers granted to Administrator
pursuant to this Section 3.2(b). The Group shall cooperate with, and at the
request of Administrator shall provide reasonable assistance to, Administrator
with the functions set forth herein. In the performance of the services
described in this Section 3.2(b), Administrator shall use commercially
reasonable efforts to collect such professional fees and shall comply with all
applicable Managed Care Contracts and all applicable laws, rules and
regulations.

         (c) Accounting. Administrator shall administer and maintain the
operation of an appropriate accounting system with respect to the operation of
the Practice, and Administrator shall perform all bookkeeping and accounting
services necessary or appropriate for the efficient operation of the Practice,
including the maintenance, custody and supervision of business records, ledgers
and reports; the establishment, administration and implementation of accounting
procedures, controls and systems; and implementation and management of
computer-based management information systems. The Group and its authorized
representatives shall have the right to review all financial books and records
maintained by Administrator relating to the operation of the Practice and to the
cash management transfer and uses contemplated by Section 3.2(d) hereof. Such
information shall be provided by Administrator to the Group in any media
reasonably requested upon reimbursement of Administrator's actual cost.

         (d) Cash Management. Administrator shall manage the cash and cash
equivalents of the Group and Administrator shall be entitled (and is hereby
authorized) to transfer such cash to the account of Administrator and to use
such cash for purposes as Administrator deems appropriate, subject to and
consistent with the terms and provisions of this Agreement. Nothing in this
Section 3.2(d) shall be construed to limit or otherwise modify the requirement
that Administrator disburse funds in fulfillment of the obligations of the Group
and Administrator under this Agreement.

         (e) Purchase of Accounts Receivable and Right of Offset. Effective each
business day of the month and subject to applicable law, Administrator shall
purchase all accounts receivable of the Group arising during the day or days
just ended and shall make payment to Group therefor or offset, without further
notice or authorization, sums owed Administrator by Group as the parties have
agreed herein. The purchase price shall be an amount equal to the aggregate face
amount of the accounts receivable being sold less contractual adjustments and


                                       12
<PAGE>   18
estimated allowances for bad debt as determined from time to time based on
recent historical collection experience of one year or less. Administrator shall
make appropriate adjustments for bad debt and contractual allowances following
the close of each fiscal quarter of the Administrator.

         (f) Obligations of Administrator. Administrator shall supply to the
Group all ordinary, necessary or appropriate services for the efficient
operation of the Practice, including without limitation, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services, information
management, preparation of Tax Returns, printing, postage and duplication
services and medical transcribing services; provided, however, that the Group
may elect to prepare its own Tax Returns, in which case, the cost of preparing
such Tax Returns in excess of $2,500 per annum shall be included in Excluded
Practice Expenses. Administrator shall prepare monthly unaudited accrual or
cash-basis (as designated by the Group) financial statements for the Group
containing a balance sheet, income statement and monthly operational reports
which detail payments, charges and accounts receivable statistics, monthly
reconciliation reports on cash management and any other financial reports
reasonably requested by a member of the Joint Planning Board designated by the
Group, which shall be delivered to the Group as soon as practicable, but no
later than thirty (30) days after the end of each calendar month. The Group may
elect to have an audit conducted with respect to such financial statements by an
accounting firm selected by Group in its sole discretion, in which case the cost
of such audit shall be included in Excluded Practice Expenses unless such audit
discloses a material discrepancy, equal to or greater than ten percent (10%) of
the residual amount to which the Group is entitled following application of the
priority of payment set forth in Section 7.6 below in which case the cost shall
be an Administrator Expense.

         (g) Records and Files.

                  (i) Administrator's Business and Financial Records. At all
times during and after the term of this Agreement, including any extensions or
renewals hereof, all business records, including but not limited to, business
agreements, books of account, personnel records, general administrative records
and all information generated under or contained in the management information
system pertaining to Administrator's obligations hereunder, and other business
information of Administrator of any kind or nature, except for patient medical
records and the Group's Records (as defined in subparagraph (ii) below), shall
be and remain the sole property of Administrator; provided that during and after
termination of this Agreement, the Group shall be entitled to reasonable access
to such records and information, including the right to obtain copies thereof in
any media reasonably requested by the Group, for any purpose related to patient
care or the defense of any claim relating to patient care or the business of
Administrator or the Group or to the relationships of the parties hereto, and
the Administrator agrees to safeguard such records for such period as may be
required by applicable federal or state law following termination of this
Agreement, but in no event less than six (6) years. Administrator hereby agrees
to preserve the confidentiality of such patient medical records and to use the
information in such records only for the limited purposes necessary to perform
management services and, within the limits of its responsibilities hereunder, to
ensure that provision is made for appropriate care for patients of the Practice.

<PAGE>   19
                  (ii) The Practice's Business and Financial Records. At all
times during and after the term of this Agreement, the business agreements,
financial, operational, corporate and personnel records and information relating
exclusively to the business and activities of the Group and patient medical
records and charts (hereinafter referred to as the "Group's Records") shall be
and remain the sole property of the Group.

                  (iii) Access to Records. At all times during and after the
term of this Agreement, each party and its authorized agents shall be entitled,
upon request and with reasonable advance notice, to obtain access (within not
more than 30 days following receipt of such notice by the other party or
parties) to all records of the other party directly related to the performance
of such party's obligations pursuant to this Agreement; provided, however, that
such right shall not allow for access to patient, medical and other records that
must be kept confidential as required by law. Either party, at its expense,
shall have the right to make copies in any media of any records to which it has
access pursuant to this subparagraph (iii).

                  (iv) Compliance with Law. The management of all files and
records by Administrator and the Group shall comply with all applicable federal,
state and local statutes and regulations.

         (h) Collections. Subject to the consent requirement contained in
Section 3.2(b)(i)(F), Administrator shall take such action as is reasonably or
lawfully necessary in the name of and on behalf of the Group to collect fees and
pay in a timely manner on behalf of Group all Practice Expenses, except as
otherwise agreed between Administrator and the Group.

         Section 3.3 Facilities.

Premises that are described in Exhibit 3.3(a) attached hereto and such other
improvements made by Administrator or Parent for the use of the Group hereunder.

property necessary or appropriate for the efficient operation of the Practice
acquired by Administrator or Parent (subject to review and approval of the Joint

(collectively, the "Personal Property"). Administrator shall maintain the
Personal Property in good condition and make or cause to be made all necessary
repairs thereto.


                                       14
<PAGE>   20
         (c) Expenses. All costs, fees, expenses and other disbursements
incurred by Administrator, Parent or their Affiliates in connection with the
Premises and the Personal Property, including, without limitation, all
reasonably necessary costs of repairs, maintenance and improvements, utility
expenses (i.e., telephone, electric, gas and water), janitorial services, refuse
disposal, real or personal property lease cost payments and expenses, interest,
refinancing expenses, depreciation, loss on disposition of assets, taxes and
casualty, liability and other insurance, shall be included in Practice Expenses.
To the extent the Premises or Personal Property are used in connection with the
Professional Operations, the costs and expenses associated with such usage shall
be allocated between Professional Expenses and Technical Expenses as approved by
the Joint Planning Board.

         (d) Disposition. Subject to provisions contained in existing agreements
to which Administrator or Parent is or becomes a party and, where necessary and
appropriate for the efficient operation of the Practice, nothing herein shall be
construed as precluding Administrator or Parent from selling, leasing or
otherwise disposing of all or any part of the Premises, Personal Property, real
property, improvements, trade names, trademarks and other intangible property;
provided, however, any such sale, lease or disposition shall be subject to the
prior review and approval of the Joint Planning Board and shall not eliminate or
diminish Administrator's obligations hereunder.

         (e) No Warranties or Representations. The Group acknowledges that
Administrator makes no warranties or representations, express or implied, as to
the fitness, suitability or adequacy of the Premises or the Personal Property,
or any other property furnished under this Agreement, for the conduct of a
medical practice or for any other particular purpose.

         Section 3.4 Acquisition and Assistance.

         (a) Employment of Physicians. Subject to consultation with the Joint
Planning Board, in the event a decision is made by the Group to employ
additional physicians, if requested by the Group, Administrator will assist the
Group in the identification and selection of physicians or physician groups or
practices that may be beneficial in the operation of the Practice. Subject to
consultation with the Joint Planning Board, in the event that a decision is made
by the Group to pursue the employment of selected physicians, if requested by
the Group, Administrator will provide recruiting, consulting, negotiating and
other advisory services in connection with such transaction. Notwithstanding the
preceding, as set forth in and subject to the provisions of Section 4.1 hereof,
the Group shall have complete control of and responsibility for the hiring of
all Physician Employees and Physician Extender Employees.

         (b) Acquisitions. In the event that the Group contemplates acquiring or
affiliating with a physician group, practice or other entity, and such
acquisition or affiliation involves the use or expenditure of Administrator's
and/or Parent's cash or other resources including the assumption of any Practice
Expenses or liabilities incurred or reasonably expected to be incurred as a
result of such an acquisition or affiliation including, without limitation,
capital and personnel (collectively, the "Resources"), then the Group shall
first consult with the Joint Planning Board and Administrator, and any decision
to make such affiliation or acquisition shall


                                       15
<PAGE>   21
be subject to prior approval of Administrator, which decision of the
Administrator shall be provided to the Group in a reasonable and timely manner
following satisfactory review of the physician group, practice or other entity
to be acquired or affiliated with and the terms and provisions of the proposed
affiliation or acquisition and in any event within 30 days following
notification of proposed transaction and receipt of all necessary information
related thereto. If such contemplated acquisition or affiliation does not
involve the use or expenditure of any of Administrator's and/or Parent's
Resources, then such decision shall be in the sole discretion of the Group.
Notwithstanding any provision contained herein to the contrary, any person or
entity with which the Group affiliates or acquires shall be subject to the terms
and conditions of this Agreement. If a decision is made to proceed with any
affiliation or acquisition of a physician group or practice, the Group may seek
from Administrator, and Administrator shall provide the Group with, consulting,
negotiation and other services including without limitation, legal, accounting
and other professional advisory services in connection with such affiliation or
acquisition, provided, however, that if the Group does not utilize the
Resources, the transaction costs including legal, accounting or other advisory
services of such affiliation or acquisition shall be the sole responsibility of
the Group.

         Section 3.5 Financial Planning and Budgeting.

         (a) Budgeting. Administrator shall collaborate with the Group and the
Joint Planning Board in the preparation of all annual capital and operating
budgets. These annual budgets shall be subject to the review, amendment and
approval or disapproval of the Board of Directors of Parent or a committee
designated by such Board of Directors. For purposes of developing the initial
annual operating budget, the Joint Planning Board shall take into account the
categories of expenses determined by Administrator and Joint Planning Board. The
projected annual operating budget for each subsequent year shall be subject to
the approval of the Joint Planning Board and shall reflect the Group's
anticipated staffing requirements for the next fiscal year, as well as other
anticipated expenses of the Practice. For purposes of developing the annual
capital budget, the Joint Planning Board will include budgeted amounts for any
anticipated expansion of existing facilities, acquisition of new facilities,
acquisition or upgrades of equipment, any practice asset acquisitions, and any
other anticipated capital expenses of the Practice.

         (b) Capital Expenditures. Subject to the terms contained herein,
Administrator will make funds available for capital expenditures and
improvements by Administrator on behalf of the Practice as follows:

                  (i) Budgeted Expenditures. All budgeted capital expenditures
and improvement projects shall be subject to final review and approval by the
Joint Planning Board prior to the making of any actual expenditure. Such review
and approval shall be based on confirming that the assumption, facts and
circumstances on which the decision to budget for such expenditure was based
still support and justify the actual expenditures.


                                       16
<PAGE>   22
                  (ii) Non-Budgeted Expenditures. Requests for non-budgeted
capital expenditures and improvement projects shall be evaluated and prepared by
the Joint Planning Board in consultation with the Group and Administrator. All
requests for non-budgeted capital expenditures and improvements at or for the
benefit of the Practice in excess of either $75,000 individually or an aggregate
amount equivalent to $2,500 multiplied by the number of Full-time Physician
Employees employed at the time the capital budget for such Group for the
applicable year is determined (provided, however, that such aggregate amount
shall not exceed $250,000 for any calendar year) must be approved by the Board
of Directors of Parent or by any committee specifically designated by the Board
of Directors of Parent for such purposes.

         (c) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital
equipment expenditures with respect to the Practice shall be reviewed and
approved by the Joint Planning Board and shall be based upon economic
feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         Section 3.6 Personnel. Administrator shall provide non-physician
professional support (other than Physician Extender Employees) including,
without limitation, nurses, technologists, physicists and administrative,
clerical, secretarial, bookkeeping and collection personnel as is reasonably
necessary for the efficient conduct of the Practice's operations. All such
personnel shall be duly qualified by education or experience for their
respective positions and shall possess all licenses which may be required by
law. Such personnel shall be employees of Administrator, and Administrator shall
determine and cause to be paid the salaries and benefits of all such personnel.
Such personnel shall be supervised by and comply with the directions and orders
of Administrator, except as otherwise required by applicable law. If the Group
is dissatisfied with the services of any such personnel who provide services
primarily for the Practice at the Premises, the Group shall consult with
Administrator, and Administrator shall in good faith determine whether the
performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether such employee should be considered for
termination. If Administrator determines to retain such employee and the Group
is still dissatisfied with the services provided by such employee after a
reasonable period of time, Administrator shall either relocate such employee or
otherwise cease to utilize such employee in providing services to the Practice
hereunder. Administrator shall maintain established working relationships
wherever possible and Administrator shall make every effort consistent with
sound business practices to honor the specific requests of the Group with regard
to the assignment of Administrator's employees.

         Section 3.7 Provider and Payor Relationships. Administrator shall
provide financial and business assistance to the Group in the negotiation,
establishment, supervision and maintenance of contracts and relationships
(collectively, the "Managed Care Contracts") with all managed care,
institutional health care providers and payors, health maintenance
organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid, insurance companies, hospitals and other
similar persons (collectively, "Managed Care Payors"). Approval, disapproval,
termination or amendment of any contract or relationship of such Managed Care
Payors with the Group shall, after consultation with the Joint Planning


                                       17
<PAGE>   23
Board, be the responsibility of the Group. Notwithstanding the preceding
language, if a contract or relationship between any Managed Care Payor and the
Group involves or affects a contract or relationship with any other physician
group or practice serviced or managed by Administrator, Parent or any of their
Affiliates (the "Other Practices") and a consensus among the Group and the Other
Practices cannot be reached regarding the contract or relationship, then the
ultimate decision as to the approval, disapproval, termination or amendment of
such contract or relationship involving the Group, the Other Practices and such
Managed Care Payor shall be determined by the affirmative vote of the Physician
Board Members (as defined below) who hold a majority of the Group Voting Power
(as defined below). For purposes of this Section 3.7, (i) the term "Physician
Board Members" shall mean (a) those members appointed by the Group who serve on
the Joint Planning Board and (b) those persons appointed by the Other Practices
who serve on the Other Practices' joint boards (in a similar capacity to the
Joint Planning Board) as part of their contractual relationship with Parent,
Administrator or any of their Affiliates, and (ii) the term "Group Voting Power"
shall mean the total voting percentage which may be cast by the Physician Board
Members on a collective basis, with the percentage of votes able to be cast by
any Group or Other Practice, as applicable, shall be equal to the quotient
determined by dividing (x) the total estimated annual professional revenues to
be generated by the Group from such Managed Care Contract as determined by
Administrator, Parent or their Affiliates, as appropriate, in its sole
discretion, by (y) the total estimated annual professional revenues to be
generated by the Group and all Other Practices from such Managed Care Contract
as determined by the Administrator, Parent or their Affiliates, as appropriate,
in its sole discretion.

         Section 3.8 Inventory and Supplies. Administrator shall order, purchase
and provide to the Group on a timely basis inventory and supplies, and such
other ordinary, necessary or appropriate materials which are requested by the
Group and which the Group shall reasonably determine to be necessary in the
operation of the Practice on the same terms commercially available to
Administrator. Such inventory, supplies and other materials shall be included in
Practice Expenses at their cost to Parent or Administrator, as the case may be.

         Section 3.9 Advertising and Public Relations. In consultation with the
Joint Planning Board, Administrator shall implement (and design where requested)
an appropriate local public relations or advertising program on behalf of the
Practice, with appropriate emphasis on public awareness of the availability of
services at the Practice. Prior to publication or distribution of such marketing
or public relations material or information, Administrator shall submit such
material to the Group for its review and approval, which shall not be
unreasonably withheld. Administrator shall also design and implement all
national or other non-local public relations or advertising programs on behalf
of the Practice, the cost of which shall be included in Administrator Expenses,
except to the extent such national programs are reasonably designed to replace
or supplement the marketing benefits derived from local public relations or

         Section 3.10 Quality Assurance. Subject to Article II, Administrator
shall assist the Group in fulfilling its obligations to its patients to maintain
a high quality of medical and professional services. Any expenses that are
related to the overall maintenance of Administrator's quality assurance program

expenses related to such program that are incurred for services provided solely
for the direct benefit of the Practice shall be included in Practice Expenses.

         Section 3.11 Other Consulting and Advisory Services. Administrator will
provide such consulting and other advisory services as reasonably requested by
the Group in all areas of the Group's business functions, including, without
limitation, financial planning, acquisition and expansion strategies,

         Section 3.12 Events Excusing Performance. In the event of strikes,
lock-outs, calamities, acts of God, unavailability of supplies or other events
over which Administrator has no control, Administrator shall not be liable to
the Group for failure to perform any of the services required hereunder and the
Group shall not have the right to terminate this Agreement pursuant to Section
10.3(b), for so long as such events continue and for a reasonable period of time
thereafter; provided however that if such events continue and Administrator is
not able to perform any material portion of the services required hereunder for
a period of 120 consecutive days or more, either Administrator or Group may
terminate this Agreement by written notice to the other.

                            Obligations of the Group

         Section 4.1 Employment of Physician Employees and Physician Extender
Employees. Except as set forth in Article V, the Group shall have complete
control of and responsibility for the hiring, compensation, supervision,
training, evaluation and termination of its Physician Employees and Physician
Extender Employees. The Group shall conduct an appropriate and reasonable due
diligence review in connection with the hiring of any physician or the
acquisition of any physician group or practice. Although Administrator may
provide payroll and other related services to the Group, the Group shall be
solely responsible for the payment of such Physician Employees' and Physician
Extender Employees' salaries and wages, payroll taxes and all other taxes now or
hereafter applicable to their employment. The Group and its Physician Employees
and Physician Extender Employees shall not have any claim under this Agreement
or otherwise against Administrator or Parent for workers' compensation,
unemployment compensation or Social Security benefits, all of which shall be the
sole responsibility of the Group. The Group shall only employ or contract with
licensed physicians or other persons meeting applicable credentialing guidelines
established by the Group after consultation with the Joint Planning Board. The
Group shall cooperate in the obtaining and retaining of professional liability
insurance by ensuring that its Physician Employees and Physician Extender
Employees, and other employees who may have malpractice exposure or liability,
are insurable and by participating in an ongoing risk management program.

         Section 4.2 Professional Services. The Group shall provide professional
services to its patients in compliance at all times with ethical standards,
laws, rules and regulations applicable to the operations of the Practice, the
Physician Employees and Physician Extender Employees. The Group shall ensure
that each Physician Employee and each Physician Extender Employee has all
required licenses, credentials, approvals or other certifications to perform his
or her duties and services for the Practice and, in the event that the Group
becomes aware of any disciplinary actions or medical malpractice actions
initiated against any Physician Employee or Physician Extender Employee, the
Group shall promptly inform Administrator of such action and the underlying
facts and circumstances. If required by applicable law, any state or federal
regulatory agency or any contractual obligations, the Group shall carry out a
program to monitor the quality of medical care practiced at the Practice;
provided, however, that the preceding language shall not limit the Group's
obligation to participate in or comply with any programs established by
Administrator or Parent for purposes of ensuring that the Group complies with
applicable law. The Group shall employ Physician Employees and Physician
Extender Employees as is necessary to provide efficient medical care to patients
of the Practice.

         Section 4.3 Medical Practice. The Group shall use and occupy the
Premises exclusively for the practice of medicine and for providing other
related services and products. Unless otherwise approved in writing in advance
by Administrator, which approval shall not be unreasonably withheld or delayed,
it is expressly acknowledged by the parties hereto that the professional medical
practice or practices conducted at the Premises shall be conducted solely by
Physician Employees, and, no other physician or medical practitioner shall be
permitted to use or occupy the Premises; provided, however, if any test or
procedure is required to be performed jointly with another physician who is not
a Physician Employee or Physician Extender Employee, then such physician may use
and occupy the Premises for purposes of performing such procedure or test so
long as the Group receives usual and customary fees in connection with such
procedure or test. The Group shall be solely and exclusively in control of all
aspects of the practice of medicine and the delivery of medical services at the
Group's facilities and at such outpatient surgery centers, acute care hospitals
and other facilities as the Group may deem appropriate from time to time. The
rendition of all professional medical services, including, but not limited to,
diagnosis, treatment, therapy, the prescription of medicine and drugs, and the
supervision and preparation of medical reports shall be the sole responsibility
of the Group. From time to time the Group, after consultation with the Joint
Planning Board, will adopt and implement fee schedules for (i) non-prepaid
patients which shall be reasonable in relation to fees generally being charged
in the same or similar market areas and (ii) for all rebillings and recovery
items on prepaid Managed Care Contracts which are authorized and permitted by
such contracts. A copy of such agreements and any amendment thereto shall be
provided to Administrator for review no later than thirty (30) days prior to the
proposed effective date thereof.

         Section 4.4 Group's Internal Matters. The Group shall be responsible
for matters involving its corporate governance, employees and similar internal
matters, including, but not limited to, preparation and contents of such reports
to regulatory authorities governing the Group that the Group is required by law
to provide, distribution of professional fee income among the Group Physician
Stockholders, disposition of the Group's property and stock (subject to any


                                       20

restrictions contained herein), hiring and firing of its employees, licensing
and implementing all compliance plans and procedures as described in Section
4.6. Except for the expenses attributable to the distribution of professional
fee income among the Group Physician Stockholders, which will be included in
Excluded Practice Expenses, the costs incurred in connection with the foregoing
matters shall be Practice Expenses.

         Section 4.5 Name. Administrator agrees that the Group shall be entitled
to use on a non-exclusive and non-transferable basis for the term of this
Agreement the names set forth on Schedule 4.5 as may be necessary or appropriate
in the performance of the Group's services and obligations hereunder.

         Section 4.6 Compliance with Laws. The Group shall, and shall use its
best efforts to cause the Physician Employees, Physician Extender Employees and
other employees of the Group to, comply with all applicable federal, state and
local laws, rules, regulations and restrictions in the conduct of the Practice's
business. Without limiting the generality of the foregoing, the Group shall
comply and shall cause each Physician Employee, Physician Extender Employee and
other employee of the Group to comply, with all laws applicable to the operation
of the Practice in the generation, transportation, treatment, storage, disposal

payment may be made in whole or in part by Medicare or Medicaid, or (ii) in
return for purchasing, leasing, or ordering, or arranging for or recommending

                              Joint Planning Board

         Section 5.1 Formation and Operation of the Joint Planning Board.

         (a) The parties hereto shall establish the Joint Planning Board which
shall be responsible for developing long-term strategic planning objectives and
management policies for the overall operation of the Practice and shall
facilitate communication and interaction between Administrator and the Practice.
The Joint Planning Board shall consist of no less than three (3) or more than
six (6) members. Administrator shall designate, in its sole discretion, two (2)
members of the Joint Planning Board, who shall serve at the pleasure of
Administrator and who may be removed or replaced by Administrator at any time.
The Group shall designate, in its sole discretion, no less than one (1) or more
than four (4) members of the Joint Planning Board, who shall serve at the
pleasure of the Group and who may be removed and replaced by the Group at any
time. Each member appointed by Administrator shall be entitled to one (1) vote
per member, and each member appointed by the Group shall be entitled to that
number of votes equal to the quotient determined by dividing (x) two (2) votes
by (y) the number of members designated by the Group to the Joint Planning
Board. The act of the members holding a majority of the voting power of the
Joint Planning Board shall be the act of the Joint Planning Board.

         (b) Each member of the Joint Planning Board shall have the right to
vote on every matter either in person, by telephone, by written consent or by
one or more agents, who are also members of the Joint Planning Board, authorized
by a written proxy signed by the member and filed with the Joint Planning Board.
A proxy shall state that it either shall be voted for or against a specific
matter or matters identified in the proxy or shall be voted identically to the
vote of the agent specified in the proxy on any and all matters that may come
before and be voted on by the Joint Planning Board. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the member executing it, before the vote pursuant
to that proxy, by a writing delivered to the Joint Planning Board stating that
the proxy is revoked, or by a subsequent proxy executed by, or attendance at the
meeting and voting in person by, the member executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by the
Joint Planning Board before the vote pursuant to that proxy is counted;
provided, however, that no proxy shall be valid after the expiration of eleven
(11) months from the date of the proxy, unless otherwise provided in the proxy.

         Section 5.2 Duties and Responsibilities of the Joint Planning Board.
The Joint Planning Board shall advise the Group on the following matters:

         (a) Capital Improvements and Expansion. Subject to Section 3.5(b), any
site or Premises renovation, expansion or reduction plans and/or capital

feasibility, productivity and then current market conditions in light of both
the particular project and the Group as a whole.

         (b) Annual Budgets. The Joint Planning Board shall collaborate with
Administrator on all annual capital and operating budgets prepared by
Administrator, as set forth in Section 3.5(b) and after the annual capital and
operating budgets have been approved as provided in Section 3.5(b), no
substantial changes may be made in such budgets without the approval of the
Joint Planning Board. For purposes of this Section 5.2, substantial means any
change individually or in the aggregate which would result in a change in excess
of five percent (5%) to the annual capital or operating budgets.

         (c) Advertising. The Joint Planning Board shall consult with
Administrator on all local advertising and other marketing of the services
performed by or for the Group.

upon the pricing, access to, and quality of such services and shall review and
adopt the fee schedule for all ancillary services.

         (f) Provider and Payor Relationships. Subject to Section 3.7, decisions
regarding the establishment or maintenance of relationships with institutional
health care providers and payors shall be approved by the Group after
consultation with the Joint Planning Board.

         (g) Strategic Planning. The Joint Planning Board shall develop a plan

time. Such plan will, among other things, identify opportunities, objectives,
and the resources required to effect such plan.

priority of capital expenditures in accordance with Section 3.5(b) hereof.

         (i) Provider Hiring. The Joint Planning Board shall consult with the

specifically provided herein, the act of the members holding a majority of the
voting power of the Joint Planning Board shall be the act of the Joint Planning
Board. The Group agrees that, unless the following are approved in advance by
the Joint Planning Board and such act of the Joint Planning Board includes the
approval by both of the members designated by Administrator, it shall take no
action or implement any decision that would (i) require Administrator to expend
funds or incur obligations beyond those set forth under Sections 3.5 or 5.2 of
this Agreement; (ii) have a material adverse effect on the amount of
Administrator's management fee under Article VII; or (iii) otherwise have a
material adverse effect on Administrator's financial interests under this

hereby agree to be bound by the act of the Joint Planning Board if such act was
approved by the members holding at least a majority of the voting power of the
Joint Planning Board. No action of the Joint Planning Board shall be effective
unless authorized by the members holding a majority of the voting power of the
Joint Planning Board present or represented by proxy at the applicable meeting.
In the event that a matter cannot be resolved by the Joint Planning Board due to
a tie vote, and no compromise can be reached, then either (x) the Board of
Directors of Parent or (y) a committee designated by the Board of Directors of
Parent containing at least one (1) physician member will make a final
determination on the matter in dispute provided that both the Group and
Administrator shall have had an opportunity to make a presentation to the Board
of Directors of Parent or a committee thereof, as applicable. A quorum of the
Joint Planning Board shall consist of the members holding a majority of the
voting power of the Joint Planning Board, present in person, by telephone, or by
proxy and the quorum must remain for the duration of the meeting.

         Section 5.4 Joint Planning Board Meetings. Meetings of the Joint
Planning Board may be held by telephone or similar communication equipment so
long as all members participating in a meeting can hear and speak to each other.

(15) business days following each meeting.

be called by fifty percent (50%) of the votes.

         (c) Notice Requirement. A member calling a special meeting must provide
all other members with ten (10) days' advance written or telephonic notice.
Notice must be given or sent to the member's address or telephone number as
shown on the records of the Joint Planning Board. Notice may be delivered
directly to each member or to a person at the member's principal place of
business who would reasonably be expected to communicate that notice promptly to
the member.

<PAGE>   31
         (d) Waiver of Notice Requirement.

                  (i) Written Waiver, Consent or Approval. Notice of a special
meeting need not be given to any member who, either before or after the meeting,
signs a waiver of notice or a written consent to the holding of the special
meeting, or an approval of the minutes of the special meeting. Such waiver,
consent or approval need not specify the purpose of the special meeting. All
such waivers, consents, and approvals shall be filed with the Joint Planning
Board records or made a part of the minutes of the special meetings.

                  (ii) Failure to Object. Notice of special meeting need not be
given to any member who attends the special meeting and does not protest before
or at the commencement of the special meeting such lack of notice.

                  (iii) Quorum. The smallest number of members that hold votes
that exceed fifty percent (50%) of all voting power shall constitute a quorum of
the Joint Planning Board.

                  (iv) Proxies. The Joint Planning Board shall provide for the

                              Restrictive Covenants

         The parties recognize that the services to be provided by Administrator

<PAGE>   32
         (b) Covenant Not to Solicit. During the term of this Agreement and for
twenty-four (24) months following the termination of this Agreement, the Group

         (c) Engagement of Administrator. If (i) this Agreement is terminated

Group or any successor thereto shall engage Administrator as the sole and
exclusive manager and administrator of the nonprofessional functions and
services of such other office, practice, hospital or health care facility on the
same terms and conditions as contained herein.

         (d) Administration's Obligations Regarding Proprietary Interest.

                  (i) Acknowledgement of Proprietary Interest. Administrator,
Parent or their Affiliates hereto recognize the proprietary interest of the
Group in any Confidential and Proprietary Information (as hereinafter defined).
Administrator, Parent and their Affiliates acknowledge and agree that any and
all Confidential and Proprietary Information of the Group ("Group's Confidential
and Proprietary Information") communicated to, learned of, developed or
otherwise acquired by Administrator, Parent and their Affiliates during the term
of this Agreement shall be the property of the Group. Administrator, Parent and
their Affiliates further acknowledge and understand that disclosure of any of
Group's Confidential and Proprietary Information will result in irreparable
injury and damage to the Group. As used herein, "Group's Confidential and
Proprietary Information" means all trade secrets and other confidential and/or
proprietary information of the Group, including information derived from
reports, investigations, research, work in progress, codes, marketing and sales
programs, financial projections, cost summaries, pricing formula, contract

                  (ii) Covenant Not-to-Divulge Confidential and Proprietary
Information. Administrator, Parent and their Affiliates acknowledge and agree
that the Group is entitled to prevent the disclosure of Group's Confidential and
Proprietary Information. Administrator, Parent and their Affiliates agree at all
times during the term of this Agreement and thereafter to hold in strictest
confidence and not to disclose to any person, firm or corporation, except as may
be necessary for the discharge of its obligations under this Agreement, and not
to use, except in the pursuit of the business of the Practice, Group's
Confidential and Proprietary Information, without the prior written consent of
the Group; unless (i) such information becomes known or available to the public
generally through no wrongful act of Administrator, Parent or their Affiliates
or their employees or (ii) disclosure is required by law or the rule, regulation
or order of any governmental authority under color of law; provided, that prior

Affiliates shall take all necessary and proper precautions against disclosure of
any of Group's Confidential and Proprietary Information to unauthorized persons
by any of its officers, directors, employees or agents. All officers, directors,
employees, and agents of Administrator, Parent and their Affiliates who will
have access to all or any part of the Group's Confidential and Proprietary
Information will be required to execute an agreement upon request, valid under
the law of the jurisdiction in which such agreement is executed, and in a form
acceptable to Administrator, Parent or their Affiliates and their counsel,
committing themselves to maintain the Group's Confidential and Proprietary
Information in strict confidence and not to disclose it to any unauthorized
person or entity. Upon termination of this Agreement for any reason, the
Administrator, Parent and their Affiliates and their employees shall cease all
use of any of the Group's Confidential and Proprietary Information and shall
execute such documents as may be reasonably necessary to evidence their
abandonment of any claim thereto.

                  (iii) Return of Materials. In the event of any termination of
this Agreement for any reason whatsoever, or at any time upon the request of the
Group, the Administrator, Parent and their Affiliates will promptly deliver or
cause to be delivered to the Group all documents, data and other information in
their possession that contain any Group's Confidential and Proprietary
Information. The Administrator, Parent and their Affiliates shall not take or

                  (i) Acknowledgement of Proprietary Interest. The Group
recognizes the proprietary interest of the Administrator, Parent and their
Affiliates in any Confidential and Proprietary Information (as hereinafter
defined). The Group acknowledges and agrees that any and all Confidential and
Proprietary Information of Administrator, Parent or their Affiliates
("Administrators's Confidential and Proprietary Information") communicated to,
learned of, developed or otherwise acquired by the Group during the term of this
Agreement shall be the property of Administrator, Parent or their Affiliates.
The Group further acknowledges and understands that its disclosure of
Administrator's Confidential and Proprietary Information will result in
irreparable injury and damage to Administrator, Parent or their Affiliates. As

financial projections, cost summaries, pricing formula, contract analyses,
financial information, projections, confidential filings with any state or
federal agency, and all other confidential concepts, methods of doing business,
ideas, materials or information (other than the Group's patient records)
prepared or performed for, by or on behalf of the parties hereto by its
employees, officers, directors, agents, representatives, or consultants.
Confidential and Proprietary Information shall not include any information
which: (i) was known to the parties hereto prior to its disclosure by the
Administrator, Parent or their Affiliate; (ii) is or becomes publicly known
through no wrongful act of the Group or any of its employees; (iii) is disclosed
pursuant to a statute, regulation or the order of a court of competent
jurisdiction, provided that the Group provides prior notice to Administrator,

                  (ii) Covenant Not-to-Divulge Confidential and Proprietary
Information. The Group acknowledges and agrees that Administrator, Parent or
their Affiliates are entitled to prevent the disclosure of Confidential and
Proprietary Information. The Group agrees at all times during the term of this
Agreement and thereafter to hold in strictest confidence and not to disclose to
any person, firm or corporation, except as may be necessary for the discharge of
its obligations under this Agreement, and not to use, except in the pursuit of
the business of the Practice, Administrator's Confidential and Proprietary
Information, without the prior written consent of Administrator, Parent and
their Affiliates; unless (i) such information becomes known or available to the
public generally through no wrongful act of the Group or its employees or (ii)
disclosure is required by law or the rule, regulation or order of any
governmental authority under color of law; provided, that prior to disclosing
any Administrator's Confidential and Proprietary Information pursuant to this
clause (iii), the Group shall, if possible, give prior written notice thereof to
Administrator, Parent and their Affiliates and provide such parties with the
opportunity to contest such disclosure. The Group shall take all necessary and
proper precautions against disclosure of any Administrator's Confidential and
Proprietary Information to unauthorized persons by any of its officers,
directors, employees or agents. All officers, directors, employees, and agents
of the Group who will have access to all or any part of the Administrator's
Confidential and Proprietary Information will be required to execute an
agreement upon request, valid under the law of the jurisdiction in which such
agreement is executed, and in a form acceptable to Administrator, Parent and
their Affiliates and its counsel, committing themselves to maintain the
Administrator's Confidential and Proprietary Information in strict confidence
and not to disclose it to any unauthorized person or entity. Upon termination


                                       29
<PAGE>   35
of this Agreement for any reason, the Group and their employees shall cease all
use of any of the Administrator's Confidential and Proprietary Information and
shall execute such documents as may be reasonably necessary to evidence their
abandonment of any claim thereto.

                  (iii) Return of Materials. In the event of any termination of
this Agreement for any reason whatsoever, or at any time upon the request of
Administrator, Parent or their Affiliates, the Group will promptly deliver or
cause to be delivered to Administrator, Parent and their Affiliates all
documents, data and other information in their possession that contains any
Administrator's Confidential and Proprietary Information regarding
Administrator, Parent and their Affiliates. The Group shall not take or retain
any documents or other information, or any reproduction or excerpt thereof,
containing any Administrator's Confidential and Proprietary Information, unless
otherwise authorized in writing by the party possessing such Administrator's
Confidential and Proprietary Information. In the event of termination of this
Agreement, the Group will deliver to Administrator, Parent and their Affiliates
all documents and data pertaining to Administrator's Confidential and
Proprietary Information of the other parties not otherwise purchased as part of
the Purchased Assets.

         (f) Third Party Beneficiaries. The members of the APPI Group not party
to this Agreement are hereby specifically made third party beneficiaries of this
Section 6.1, with the power to enforce the provisions hereof.

         Section 6.2 Restrictive Covenants. The Group shall obtain and enforce
formal agreements with each Physician Employee who is either (i) a Group
Physician Stockholder or (ii), to the extent permitted under applicable law, a
Full-time Physician Employee which each contain certain restrictive covenants
thereof pertaining to covenants not to compete and/or solicit with and not to
divulge the Confidential and Proprietary Information of any member of the APPI
Group or the Practice (the "Restrictive Covenants"). Except as otherwise
approved by the Joint Planning Board, each Group Physician Stockholder or
Full-time Physician Employee shall agree, during the term of his/her employment
or contractor agreement with the Practice and for a period of twenty-four (24)
months after any termination of such agreement: (i) not to establish, operate or
provide professional radiology services at any office, practice, hospital or
health care facility providing services substantially similar to those provided
by the Practice pursuant to this Agreement within 15 miles of any location of
any Practice Site(s) and (ii) to be bound by non-solicitation, noncompetition
and nondisclosure of confidential/proprietary information and engagement of
Administrator covenants similar to those applicable to the Group as contained in
Section 6.1 hereof. Except as otherwise approved by the Joint Planning Board,
each Group Physician Stockholder or Full-time Physician Employee shall agree
that during the term of his/her employment or contractor agreement with the
Group (w) not to practice radiological medicine other than at the Premises or
such other location or Practice Site(s) as approved by the Joint Planning Board;
(x) to devote substantially all of his or her professional time, effort and
ability to the Practice; (y) to request in writing and receive in writing prior
approval from the Joint Planning Board to engage in any outside medical
activities; and (z) to turn over to the Practice, to be included in Professional
Revenues attributed to the Practice, any income derived by such Group Physician
Stockholder or Full-time Physician Employee from any outside medical activity or
related source from the following medically-related activities: teaching,
consulting,


                                       30
<PAGE>   36
medical research, inventions developed utilizing the Group's or the Practice's
time and material, testimony for litigation, and insurance examinations. The
Group shall not materially amend, alter or otherwise change any term or
provision of any Stockholder Employment Agreement or Physician Employee
Employment Agreement relating to the foregoing covenants in this Section 6.2
without the prior written consent of Administrator; notwithstanding the
foregoing, any such amendment, alteration or change shall not be inconsistent
with the terms or provisions of this Agreement. Following termination of this
Agreement, the Group shall not amend, alter or otherwise change any term or
provision of the Restrictive Covenants, unless such provisions are no longer in
force and effect pursuant to the terms of the applicable Stockholder Employment
Agreement or Physician Employee Employment Agreement at the time of termination
of this Agreement. In the event the Purchase Assets are acquired by the Group
pursuant to Article X, the obligation of the Group to enforce Restrictive
Covenants shall be limited to enforcement of non-solicitation and nondisclosure
of confidential/proprietary information covenants.

         Section 6.3 Enforcement of Restrictive Covenants and Other Provisions.
The Group shall enforce the Stockholder Employment Agreements and, to the extent
permitted under applicable law, the Physician Employee Employment Agreements,
including, without limitation, the Restrictive Covenants. The costs and expenses
of such enforcement shall be included in Professional Expenses and all damages
and other amounts recovered thereby shall be included in Professional Revenues.
In the event that, after a request by Administrator, the Group does not pursue
any remedy that may be available to it by reason of a breach or default of the
Restrictive Covenants or any other provision of the Stockholder Employment
Agreements and, to the extent permitted under applicable law, the Physician
Employee Employment Agreements, upon the request of Administrator, the Group
shall assign to Administrator such causes of action and/or other rights it has
related to such breach or default and shall cooperate with and provide
reasonable assistance to Administrator with respect thereto; in which case, all
costs and expenses incurred in connection therewith shall be borne by
Administrator and shall be included in Administrator Expenses, and Administrator
shall be entitled to all damages and other amounts recovered thereby. In the
event the Purchase Assets are acquired by the Group pursuant to Article X, the
obligation of the Group to enforce Restrictive Covenants shall be limited to
enforcement of non-solicitation and nondisclosure of confidential/proprietary
information covenants.

         Section 6.4 Remedies. Administrator and the Group acknowledge and agree
that a remedy at law for any breach or attempted breach of the provisions of
this Article VI shall be inadequate, and therefore, either party shall be
entitled to specific performance and injunctive or other equitable relief in the
event of any such breach or attempted breach, in addition to any other rights or
remedies available to either party at law or in equity. Each party hereto waives
any requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or other equitable relief. If any provision of
the Restrictive Covenants or this Article VI relating to the restrictive period,
scope of activity restricted and/or the territory described therein shall be
declared by a court of competent jurisdiction to exceed the maximum time period,
scope of activity restricted or geographical area such court deems reasonable
and enforceable under applicable law, the time period, scope of activity
restricted and/or area of restriction held reasonable and enforceable by the
court shall thereafter be the restrictive period,


                                       31
<PAGE>   37
scope of activity restricted and/or the geographical area applicable to such
provision of the Restrictive Covenants or this Article VI. The invalidity or
non-enforceability of any provision of the Restrictive Covenants or this Article
VI in any respect shall not affect the validity or enforceability of the
remainder of the Restrictive Covenants or this Article VI or of any other
provisions of this Agreement.

         Section 6.5 Condition Precedent to Release of Obligations. In the event
a Group Physician Stockholder or Full-time Physician Employee terminates his/her
employment agreement with the Group, the Group shall be entitled to release
(with the consent of Administrator in its sole and absolute discretion) such
Group Physician Stockholder or Full-time Physician Employee from the restrictive
covenants contained in Section 6.2, above. In the event the Group elects to
release such Group Physician Stockholder or Full-time Physician Employee, the
Group hereby covenants that it shall obtain a formal agreement between each
Group Physician Stockholder or Full-time Physician Employee, as the case may be,
and Administrator which provides that, for a period of two (2) years following
termination of any employment agreement with the Group, such Group Physician
Stockholder or Full-time Physician Employee agrees to (a) engage Administrator
as the sole and exclusive manager and administrator of the non-medical functions
and services of said Group Physician Stockholder's or Full-time Physician
Employee's medical practice and (b) pay to Administrator the identical amount
[NY only] of revenues paid by the Group to the Administrator attributable to
such Group Physician Stockholder or Full-time Physician Employee derived from
such Group Physician Stockholder's or Full-time Physician Employee's performance
of professional medical services within 15 miles of any Practice Site.

         Section 6.6 Service Area Rights and Obligations.

         (a) Primary Service Area. During the term of this Agreement and within
any Primary Service Area, Parent, Administrator or their Affiliates shall not,
without the prior written consent of the Group, (i) acquire or lease the
non-medical assets (through an asset acquisition, merger or other consolidation
or otherwise) of any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists, (ii) acquire any imaging center where, within a reasonable time
period following such acquisition, the Group will not be entitled to provide
professional Radiology services for such imaging center, or (iii) contract to
provide management and administrative services similar to those provided under
this Agreement to any Radiologist, group of Radiologists or professional
corporation or association (or other professional entity) whose owners are
Radiologists. Following a request for written consent by Administrator, Parent
or their Affiliates hereunder, the Group shall respond upon the earlier of (i)
within thirty (30) days from receipt of such request and all other necessary
information related thereto or (ii) one-half of the time during which
Administrator, Parent or their Affiliates must respond. In the event the Group,
Parent, Administrator or their Affiliates acquire a Professional Service
Opportunity, the Group shall accept such Professional Service Opportunity and
shall perform any and all professional Radiology services that are reasonably
required at such location(s) in accordance with the terms and provisions of this
Agreement; provided (x) that the professional reimbursement for such services is
reasonable in relation to the overall market environment and


                                       32
<PAGE>   38
work effort required and (y) the Group shall not be required to employ any
Radiologist previously associated with such Professional Service Opportunity.

         (b) Secondary Service Area. During the term of this Agreement and
within any Secondary Service Area, Parent, Administrator or their Affiliates
shall first offer to the Group any New Professional Service Opportunity;
provided, however, that this provision shall not be applicable to any merger of
a Radiologist, group of Radiologists or professional corporation or association
(or other professional entity) whose owners are Radiologists with the Group.
Administrator shall give written notice (the "Administrator Notice") to the
Group describing the New Professional Service Opportunity. Within the earlier of
(i) thirty (30) days or (ii) one-half of the time during which the
Administrator, Parent or their Affiliates must respond to an offer described in
the Administrator's Notice, the Group shall deliver to Administrator a written
notice stating whether or not the Group elects to accept or reject the New
Professional Service Opportunity which election shall be binding on the Group.
If the Group does not elect to exercise the right or fails to provide the notice
to Administrator within the time frame herein provided, Administrator shall be
released from the right of first offer with respect to that particular New
Professional Service Opportunity. Prior to consummating any asset acquisition,
merger or other consolidation of any Radiologist, group of Radiologists, or
professional corporation or association (or other professional entity) whose
owners are Radiologists within any Secondary Service Area, Administrator shall
first consult with the Joint Planning Board.

         (c) Determination of Primary and Secondary Service Area. The existence
and location of each of the Group's Primary Service Areas and Secondary Service
Areas shall be determined each time the Group, Parent, Administrator or their
Affiliates propose an acquisition, management relationship, Professional Service
Opportunity or New Professional Service
Opportunity as contemplated in subsections (a) and (b) above.

         (d) Dispute Resolution. Any disputes regarding the interpretation of
the provisions of this Section 6.6 shall be referred to and decided by the Joint
Planning Board as provided in Section 5.3 of this Agreement.

         (e) Definitions. The definitions utilized in connection with this
Section 6.6 shall have the following meanings:

             "New Professional Service Opportunity" shall mean a Professional
Service Opportunity pursuant to which the Group or any other member of an APPI
Group managed by Parent, Administrator or their Affiliates is not currently
providing professional Radiology services.

             "Primary Service Area" shall mean that area within a five (5) mile

Parent or their Affiliates for which the Group provides professional Radiology
services or any hospital at which on-site professional Radiology services are
then provided by Physician Employee(s) or Physician Extender Employee(s) of the
Group.


                                       33
<PAGE>   39

             "Professional Service Opportunity" shall mean any opportunity to

following the Acquisition Effective Date, that area which extends ten (10) miles
beyond the boundary of any Primary Service Area and (ii) during the remaining

boundary of any Primary Service Area.

         Section 6.7 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 10.4(a),(b) or (c), the provisions of Section 6.2
and Section 6.3 shall survive such termination if the actions or events giving
rise to a breach of the Restrictive Covenants or other provisions occurred prior
to such termination. If the Agreement is terminated pursuant to the preceding
sentence, all of the provisions of Section 6.1 shall survive. However,
regardless of the reason for termination, or upon expiration of this Agreement,
the provisions of Section 6.1(d),(e),(f) and (g) shall survive such termination
or expiration indefinitely unless otherwise expressly limited as to a period of
time.

         Section 6.8 Definition. The term "Full-time Physician Employee" as used
in Sections 6.2 and 6.5 of this Article VI only, shall mean a Full-time
Physician Employee who shall have been employed by the Group for two (2) years;
provided, that such Full-time Physician Employee shall enter into a written
agreement at the commencement of the later of (i) his/her employment or (ii) the
Acquisition, which includes the provisions set forth in Sections 6.2 and 6.5,
above, and acknowledges his/her understanding that such provisions will be
enforceable against such Full-time Physician Employee following such two (2)
year period. Notwithstanding the foregoing, the Group shall be entitled to apply
to the Joint Planning Board for the purpose of requesting that a particular
Full-time Physician Employee not be required to execute an employment agreement
that contains the provisions contained in Sections 6.2 and 6.5, which such
release by Administrator shall not be unreasonably withheld.


                                   ARTICLE VII

                       Financial and Security Arrangements

         Section 7.1 Service Fee. The Group and Administrator agree that the
compensation set forth in this Article VII is being paid to Administrator in
consideration of the services provided and the substantial commitment and effort
made by Administrator hereunder and that such fees have been negotiated at arms'
length and are fair, reasonable and consistent with fair market value.
Administrator shall be paid the service fee (the "Service Fee") as set forth on


                                       34
<PAGE>   40
Exhibit 7.1 hereto. Payment of the Service Fee is not intended to and shall not
be interpreted or implied as permitting Administrator to share in the Group's
fees for medical services but is acknowledged as the negotiated fair market
value compensation to Administrator considering the scope of services and the
business risks assumed by Administrator.

         Section 7.2 Payments. Except as otherwise set forth on Exhibit 7.1
hereto, the amounts to be paid to Administrator under this Article VII shall be
calculated by Administrator on the accrual basis of accounting and shall be
payable monthly. Payments due for any Service Fee shall be made by the Group
each calendar month as provided herein and shall be paid on the 15th day
following the end of such month (or the first preceding day that is a business
day if the 15th day is not a business day) (a "Payment Date"). Except as
otherwise set forth on Exhibit 7.1, such amounts paid shall be estimates based
upon available information for such month, and adjustments to the estimated
payments shall be made to reconcile final amounts due under Section 7.1 on the
next Payment Date.

         Section 7.3 Advances. The Group shall be entitled to an advance from
Administrator of such additional sums, over and above the Group's right to the
amounts otherwise set forth in this Article VII, as shall be required by the
Group to pay Practice Expenses (excluding Technical Expenses) consistent with
the annual capital and operating budgets of the Practice (prepared as provided
in Section 3.5 hereof), the Service Fee as provided in Exhibit 7.1 hereto and
Excluded Practice Expenses at the discretion of Administrator. Any amounts
advanced to the Group pursuant to this Section 7.3 shall be repaid by the Group
in such priority as set forth in Section 7.6 below and shall bear interest at
Parent's then available, borrowing rate offered by Administrator's or Parent's
senior lender (which rate shall be charged consistently to each physician group
who enters into a Service Agreement with Administrator) until all such amounts
of principal and interest are repaid to Administrator as provided herein.
Notwithstanding the foregoing, no interest shall accrue or be paid by the Group
for amounts advanced to the Group pursuant to this Section 7.3 during the
forty-five (45)-day period immediately following the Acquisition Effective Date.

         Section 7.4 Security Agreement. In order to enforce its rights granted
hereunder and subject to applicable law, the Group shall execute a Security
Agreement in substantially the form attached hereto as Exhibit 7.4 (the
"Security Agreement"), which Security Agreement grants a security interest in
all of the Group's accounts receivable (as more fully described in the Security
Agreement) to Administrator. In addition, the Group shall cooperate with
Administrator and execute all necessary documents in connection with the pledge
of such accounts receivable to Administrator or at Administrator's option, its
lenders.

         Section 7.5 Adjustment of Fees. In addition to the adjustments provided
for in Section 7.2, Service Fees payable by Group pursuant to this Article VII
shall be adjusted as appropriate upon agreement of the parties upon the
divestiture or acquisition by the Group of, or affiliation with, a radiology or
diagnostic practice group. Whether or not Parent capital stock or funds are
utilized to fund the acquisition or affiliation, the Service Fee and other
related provisions of this Agreement shall be adjusted as agreed upon by the
parties on a case by case basis. Under either acquisition or affiliation model,
the precise adjustment to the Service Fee


                                       35
<PAGE>   41
and to other related provisions of this Agreement shall be a joint decision of
the parties, shall be memorialized in a written amendment to this Agreement, and
shall be based upon the methodology used to generally determine Services Fees
hereunder.

         Section 7.6 Priority of Payments. Administrator shall administer and
make disbursements from amounts deposited into the Deposit Account or
transferred from the Deposit Account to pay (including, without limitation the
making of advances as provided in Section 7.3) the Practice Expenses and
Excluded Practice Expenses as the same become due and payable, and for which the
Group shall remain responsible; provided, however, that if Technical Expenses
exceed Technical Revenues, then the amount by which Technical Expenses exceed
Technical Revenues shall be excluded for purposes of the priority of payments
set forth below and the Group shall not be responsible for such amount. In
performing its obligations pursuant to Article III, on the fifteenth (15th) day
following the end of each calendar month, Administrator shall apply an amount
equal to the aggregate face amount of the prior month's accounts receivables,
less contractual adjustments and estimated allowances for bad debt as determined
in accordance with Section 3.2(e), in the following order of priority:

         (a)      payment of all accrued Practice Expenses for the prior month
                  (subject to the proviso in the preceding sentence);

         (b)      payment of the accrued Service Fee for the prior month;

         (c)      payment of the outstanding balance of all amounts advanced to
                  the Group through the end of the prior month, and applicable
                  interest thereon (as contemplated in Section 7.3); and

         (d)      payment of all Excluded Practice Expenses.

Any amounts which remain following the payment of the items set forth in
subparagraphs (a) through (d) above shall be deposited into the Group Account on
the fifteenth (15th) day following the end of each calendar month (or the first
preceding day if the 15th day is not a business day).


                                  ARTICLE VIII

                                     Records

         Section 8.1 Records. All records relating in any way to the operation
of the Practice (other than Group Records) shall, subject to the obligations of
the Practice to maintain patient medical records pursuant to Section 3.2(g), at
all times be the property of Administrator as set forth in Section 3.2(g).
During the term of this Agreement, and for a reasonable time thereafter,


                                       36
<PAGE>   42
the Group or its agents shall have reasonable access during normal business
hours to the Group's and Administrator's personnel and financial records
relating to the Practice, including, but not limited to, records of collections,
expenses and disbursements as kept by Administrator in performing
Administrator's obligations under this Agreement, and the Group may copy any or
all such records.


                                   ARTICLE IX

                          Insurance and Indemnification

         Section 9.1 Insurance to be Maintained by the Group.

         (a) During the term of this Agreement, the Group shall maintain
comprehensive professional medical/malpractice liability insurance with such
carrier as determined jointly by Administrator and the Group with minimum legal
limits or such higher limits as shall be required under the Group's contracts
with hospitals or other third parties. Such insurance shall be on a per claim
and per physician basis and a separate limit for the Group to the extent
available and permitted by law with such deductible as is mutually agreeable by
Administrator and the Group. All comprehensive professional medical/malpractice
liability insurance premiums and deductibles shall be included in Practice
Expenses; provided, that if the Group elects to maintain coverage that exceeds
minimum requirements, such additional premiums shall be included in Excluded
Practice Expenses. All costs, expenses and liabilities incurred by the Group in
excess of the limits of such policies identified in the preceding sentence shall
be included in Excluded Practice Expenses. Administrator, Parent or their
Affiliates shall attempt to secure excess liability for the types of coverages
contemplated by this Section 9.1(a). If successful, the Group shall have the
opportunity to purchase at Administrator's cost, as an Excluded Practice
Expense, such coverage to the extent permitted by the then-applicable
restrictions set forth in such policy.

         (b) The Group, Administrator and Parent each waives any right one may
have against the other, to the extent allowed by the waiving party's insurance
coverage, on account of any loss or damage occasioned to any party by another
party, their respective real and personal property, the Premises or its
contents, arising from any risk generally covered by fire and extended coverage
insurance or from vandalism or malicious mischief; and the parties, on behalf of
their respective insurance companies, waive any right to subrogation, except
when such loss or damage is due to the gross negligence or willful misconduct of
the other party.

         Section 9.2 Insurance to be Maintained by Administrator. During the
term of this Agreement, Administrator will provide and maintain (i) as a
Technical Expense, comprehensive professional medical/malpractice liability
insurance for all applicable employees of Administrator and (ii) as a Practice
Expense, comprehensive general liability and property insurance covering the
Practice's premises (including, without limitation, the Premises), personal
property and operations with such limits and coverages as a reasonable business
person under similar circumstances would maintain. All costs, expenses and
liabilities incurred by Administrator in


                                       37
<PAGE>   43
excess of the limits of such policies identified in subsections (i) and (ii)
hereof shall be included in Administrator Expenses.

         Section 9.3 Continuing Liability Insurance Coverage. The Group shall
obtain or require each of its Physician Employees and Physician Extender
Employees to obtain continuing liability insurance coverage under either a "tail
policy" or a "prior acts policy," with the same limits and deductibles as the
insurance coverage provided pursuant to Section 9.1 upon the termination of such
physician's relationship with the Group for any reason, unless such physician
was covered with an occurrence-based policy while employed or retained by the
Group. In the event that the Group, any Physician Employee or Physician Extender
Employees fails to obtain such continuing liability insurance coverage,
Administrator may do so. The cost of such continuing liability insurance
coverage shall be included in Practice Expenses unless such cost is borne by the
Physician Employee.

         Section 9.4 Additional Insureds. The Group and Administrator agree to
use their reasonable efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs. The
additional cost, if any, associated therewith shall be a Practice Expense.

         Section 9.5 Indemnification.

         (a) By the Group. The Group shall indemnify, defend and hold
Administrator, Parent, their Affiliates and their respective officers,
directors, shareholders, employees, agents, attorneys and consultants (other

agents or consultants of the Group) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), not covered by insurance (including self-insured
insurance and reserves), whenever arising or incurred, that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the
performance of medical services or the performance of any intentional acts,
negligent acts or omissions by the Group and/or its shareholders, employees
and/or subcontractors (other than Administrator, Parent, Affiliates or their
employees, officers, directors, agents, attorneys and consultants) during the
term of this Agreement. Provided, however, that in the event an indemnification
obligation under the preceding sentence arises as of the result of any act or
omission of a person who is an officer, shareholder or other equity holder,
director, employee, agent, attorney or consultant of Administrator, Parent or
any of their Affiliates (other than in connection with the activities of the
Joint Planning Board), such person shall not be entitled to indemnification in
connection therewith and any other adjustment as is equitable shall be made to
the Group's indemnification obligation arising thereby.

         (b) By the Administrator. Administrator and Parent, jointly and
severally, shall indemnify, defend and hold the Group and its officers,
shareholders, directors, employees, agents, attorneys and consultants, harmless
from and against any and all liabilities, losses, damages, claims, causes of
action and expenses (including reasonable attorneys' fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or

of the performance of any intentional acts, negligent acts or omissions by
Administrator, Parent or Affiliates and/or any of their respective shareholders,
employees and/or subcontractors (other than the Group or its employees) during
the term of this Agreement. Provided, however that in the event an
indemnification obligation under the preceding sentence arises as a result of
any act or omission of a person who is an officer, shareholder or other equity
holder, director, employee, agent, attorney or consultant of the Group (other
than in connection with the activities of the Joint Planning Board), such person
shall not be entitled to indemnification in connection therewith and any other
adjustment as is equitable shall be made to Administrator's or Parent's
indemnification obligation arising thereby.

                              Term and Termination

         Section 10.1 Term of Agreement. This Agreement shall commence on the
date hereof and shall expire on the 40th anniversary hereof unless earlier
terminated pursuant to the terms of either Section 10.3 or Section 10.4 or
automatically extended pursuant to the terms of Section 10.2.

         Section 10.2 Extended Term. Unless earlier terminated as provided for
in either Section 10.3 or Section 10.4, the term of this Agreement shall be
automatically extended for additional terms of five (5) years each, unless
either party delivers to the other party, not less than twelve (12) months nor
earlier than fifteen (15) months prior to the expiration of the preceding term,
written notice of such party's intention not to extend the term of this
Agreement.

         Section 10.3 Termination by the Group. The Group may, in its sole
discretion, terminate this Agreement by giving written notice thereof to
Administrator (after the giving of any required notices and the expiration of
any applicable waiting periods set forth below) upon the occurrence of any the
following events:

         (a) Administrator or Parent shall admit in writing its inability to
generally pay its debts when due, apply for or consent to the appointment of a
receiver, trustee or liquidator of all or substantially all of its assets, file
a petition in bankruptcy or make an assignment for the benefit of creditors, or
upon other action taken or suffered by Administrator or Parent, voluntarily or
involuntarily, under any federal or state law for the benefit of creditors,
except for the filing of a petition in involuntary bankruptcy against
Administrator or Parent which is dismissed within ninety (90) days thereafter.

         (b) Administrator or Parent shall default in the performance of any
material duty or material obligation imposed upon it by this Agreement (a
"Material Administrator Default") and such default shall continue for a period
of sixty (60) days after written notice thereof has been given to Administrator
by the Group with a copy to the financial institution contemplated in Section
12.1(a) at the address provided by Administrator, provided that the Group may
terminate


                                       39
<PAGE>   45
this Agreement, if and only if, such termination shall have been approved by the
affirmative vote of the holders of two-thirds of the interests of the equity
holders of the Group. The Group agrees that the financial institution
contemplated in Section 12.1(a) shall have the right, but not the obligation, to
cure any Material Administrator Default. Notwithstanding anything to the
contrary in this Agreement, following receipt by Administrator of the notice of
a Material Administrator Default and until such Material Administrator Default
shall be cured, the Group may take such action as may be reasonably required to
cover such Material Administrator Default so as to maintain for the Group the
same level of service as before the Material Administrator Default, without
prejudicing in any way the Group's other rights and remedies, and may offset all
of its costs from the amounts which may otherwise be due to Administrator under
this Agreement.

         (c) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         Section 10.4 Termination by Administrator. Administrator may, in its
sole discretion, terminate this Agreement by giving written notice thereof to
the Group (after the giving of any required notices and the expiration of any
applicable waiting periods set forth below) upon the occurrence of any of the
following events:

         (a) The Group shall default in the performance of any material duty or
material obligation imposed upon it by this Agreement (a "Material Group
Default") and (i) the Group fails to deliver to Administrator within thirty (30)
days after written notice of such Material Group Default has been given to Group
a written plan (reasonably acceptable to Administrator) detailing the methods
and procedures that the Group shall utilize to cure such Material Group Default,
(ii) the Group has delivered a plan but has failed to utilize its best efforts
to cure such Material Group Default within sixty (60) days after written notice
thereof has been given to the Group by Administrator or (iii) the Group has
delivered the plan but, after utilizing its best efforts, is unable to cure such
Material Group Default within ninety (90) days after written notice thereof has
been given to the Group by Administrator. The term "Material Group Default" for
purposes of this Section 10.4 shall include, but not be limited to, (A) the
Group's admission in writing of its inability to generally pay its debts when
due, application for or consent to the appointment of a receiver, trustee or
liquidator of all or substantially all of its assets, filing of a petition in
bankruptcy or making an assignment for the benefit of creditors, or upon other
action taken or suffered by the Group, voluntarily or involuntarily, under any
federal or state law for the benefit of debtors, except for the filing of a
petition in involuntary bankruptcy against the Group which is dismissed within
ninety (90) days thereafter or (B) the Group or any Physician Employee (1) fails
to adhere to any compliance plan, policy, or manual as described in Section 4.6
hereof that has been approved by the Group and made applicable to all
shareholders and employees of the Group, or (2) engages in any conduct or is
formally accused of conduct for which the Group's ability or license, or a
Physician Employee's license


                                       40
<PAGE>   46
to practice medicine reasonably would be expected to be subject to revocation or
suspension, whether or not actually revoked or suspended, or (3) is notified in
writing of any adverse action by any state or federal department or agency that
has the effect of either excluding that individual from participating in or from
receiving reimbursement under any program funded by the federal government or by
any state government, notwithstanding any available post-sanction remedies, or
(4) is otherwise disciplined by any licensing, regulatory or professional entity
or institution, the result of any of which event does or is reasonably expected
to materially adversely affect the Practice, the result of any of which event
described in subparagraphs (1) through (4) above, in the absence of termination
of a Physician Employee or a Physician Extender Employee or other action of the
Group to monitor and cure such act or conduct by such employee, does or
reasonably would be expected to materially and adversely affect the Practice or
the Group. Notwithstanding anything to the contrary in this Agreement, following
receipt by the Group of the notice of a Material Group Default, and until such
Material Group Default shall be cured, the Administrator may take such action as
may be reasonably required to cover such Material Group Default so as to
maintain for the Administrator the same level of service at the Premises as
before the Material Group Default, without prejudicing in any way Administrator
other rights and remedies, and may offset all of its costs of cover from amounts
which may otherwise due to the Group under this Agreement.

         (b) An independent law firm with nationally recognized expertise in
health care law and acceptable to the parties hereto renders an opinion to the
parties hereto that (i) a material provision of this Agreement is in violation
of applicable law or any court or regulatory agency enters an order finding a
material provision of this Agreement is in violation of applicable law and (ii)
this Agreement can not be amended pursuant to Section 11.6 hereof to cure such
violation.

         (c) At any time during the five-year period following the Acquisition
Effective Date if more than thirty-three and one-third percent (33 1/3%) of the
total number of Group Physician Stockholders and Full-time Physician Employees
retained or employed by the Group at the time of the Acquisition Effective Date
are no longer employed or retained by the Group for reasons other than (i)
death, (ii) permanent disability, (iii) loss of a hospital contract or
privileges for reasons other than voluntary resignation by the Group or a
failure to renew or a failure to respond to a reasonable proposal to extend the
term of such contract or (iv) voluntary closing of facilities by Administrator.
For purposes of this Section 10.4(c), if Parent and/or Administrator are
notified in writing by the Group at or prior to the Acquisition Effective Date
of any Physician Employee [or Physician Extender Employee] that intends to
retire prior to expiration of such five-year period, then such Physician
Employee or Physician Extender Employee shall not be counted for purposes of
determining the above percentage.

         Section 10.5 Effective Date of Termination. Any termination of this
Agreement shall be effective (the "Termination Date") as follows:

         (a) Immediately upon receipt of a termination notice pursuant to
Section 10.3 or Section 10.4 (a "Termination Notice") and expiration of
applicable cure periods; or


                                       41
<PAGE>   47
         (b) Upon the expiration of this Agreement pursuant to Sections 10.1 or
10.2.

         Section 10.6 Purchase of Assets. Upon the termination of this
Agreement, subject to the provisions of subparagraphs (a) through (e) set forth
below, if Administrator is the defaulting party, the Group shall have the option
to require Administrator and/or Parent to sell to the Group, and if the Group is
the defaulting party, Administrator and/or Parent shall have the option to
require the Group to purchase from Administrator and/or Parent, the Purchase
Assets and assume the Practice Related Liabilities below:

         (a) Purchase Assets. The Group shall purchase, free and clear of all
liens and encumbrances other than those arising from Practice Related
Liabilities (as defined below), from Administrator and/or Parent or its
Affiliates, as the case may be, pursuant to subparagraph (c) below, all assets,
tangible or intangible real or personal, of Administrator, Parent or their
Affiliates that relate primarily to the Practice other than Administrator's,
Parent's or their Affiliates' accounting and financial records (the "Purchase
Assets"), including, but not limited to, without duplication, (i) all equipment,
furniture, fixtures, furnishings, inventory, supplies, improvements, additions
and leasehold improvements utilized by the Practice, (ii) any real estate owned
by Administrator, Parent or Affiliates that is occupied by or used primarily for
the benefit of the Practice, (iii) all unamortized intangible assets (including,
without limitation, goodwill) set forth on the financial statements of
Administrator, Parent or their Affiliates used solely in connection with the
Practice or otherwise resulting from the Acquisition; provided, however, that no
amortization with respect to the goodwill associated with the Acquisition shall
be set forth on such financial statements, (iv) all Confidential and Proprietary
Information that relates solely to the Practice, and (v) all other assets that
would be set forth on a balance sheet of Administrator, Parent or their
Affiliates prepared as of the date of the Purchase Closing relating primarily to
the Practice.

         (b) Practice Related Liabilities. The Group shall assume all of
Administrator's and its Affiliates' liabilities, debt, payables and other
obligations (including lease and other contractual obligations), or portions
thereof, which relate directly or are directly attributable to the Practice
and/or the Purchase Assets other than previously accrued Practice Expenses (the
"Practice Related Liabilities").

         (c) Purchase Price. The Purchase Price shall be the lesser of (i) Fair
Market Value of the Purchase Assets subject to the assumption of the Practice
Related Liabilities or (ii) the value of the Actual Consideration (defined
below)(alternatively, the "Purchase Price"); provided, however, the Purchase
Price shall not be less than the net book value of the Purchase Assets at the
Termination Date. The Purchase Price shall be paid pursuant to Section 10.7. For
purposes of this subparagraph (c), the term "Actual Consideration" shall mean
(i) cash consideration paid to the Group pursuant to the Acquisition Agreement
and (2) an amount equal to the number of shares of Parent Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, reorganizations,
or any similar transaction whereby the Parent Common Stock is increased or
decreased or exchanged for a different number or kind of securities) issued
pursuant to the Acquisition Agreement multiplied by the fair market value of
Parent Common Stock immediately prior to the time that a Termination Notice is
provided pursuant to Section 10.7. The Purchase


                                       42
<PAGE>   48
Price shall be appropriately adjusted to offset and account for any monetary
obligations of the Group or Administrator owing to the other as provided herein.

         (d) Exercise of Option.

                  (i) The Group. Upon a termination of this Agreement, the Group
shall be entitled to exercise its option to require Administrator, Parent or
their Affiliates to sell the Purchase Assets and shall assume the Practice
Related Liabilities pursuant to this Section 10.6 at any time (unless this
Agreement is terminated pursuant to Section 10.4(a) or 10.4(c)).

                  (ii) Administrator. Upon termination of this Agreement,
Administrator shall be entitled to exercise its option to require the Practice
to purchase the Purchase Assets and assume the Practice Related Liabilities
pursuant to this Section 10.6 (i) during the five-year period following the
Acquisition Effective Date if this Agreement is terminated pursuant to Sections
10.3(c), 10.4(b) or 10.4(c) and (ii) at any time in the event of a termination
pursuant to Section 10.4(a).

         (e) Notice. Each party shall exercise its option under this Section
10.6 by giving written notice thereof in the Termination Notice, if applicable,
or prior to ninety (90) days before the Termination Date if this Agreement
expires pursuant to Sections 10.1 or 10.2.

         Section 10.7 Terms of Purchase. The closing of the transactions
contemplated by Section 10.6 (the "Purchase Closing") shall occur (a) on the
Termination Date if this Agreement expires pursuant to the terms of Sections
10.1 and 10.2, or (b) on a date mutually acceptable to the parties hereto that
shall be within 180 days after receipt of a Termination Notice. The parties
shall enter into an asset purchase agreement containing representations,
warranties and conditions customary to a transaction of this size involving the
purchase and sale of similar businesses. Subject to the conditions set forth
below, at the Purchase Closing, Administrator, Parent and/or their Affiliates,
as the case may be, shall transfer and assign the Purchase Assets to the Group,
and in consideration therefor, the Group shall (a) pay to Administrator, Parent
and/or their Affiliates an amount in cash or, at the option of the Group
(subject to the conditions set forth below), Parent Common Stock (valued
pursuant to Section 10.6(c) hereof), or some combination of cash and Parent
Common Stock equal to the Purchase Price and (b) assume the Practice Related
Liabilities. The structure of the transaction set forth in this Section 10.7
shall, if possible, be structured as a tax-free transaction under applicable
law. Each party shall execute such documents or instruments as are reasonably
necessary, in the opinion of each party and its counsel, to effect the foregoing
transaction. The Group shall, and shall use its best efforts to cause each
shareholder of the Group to, execute such documents or instruments as may be
necessary to cause the Group to assume the Practice Related Liabilities and to
release Administrator, Parent and/or their Affiliates, as the case may be, from
any liability or obligation with respect thereto. In the event the Group desires
to pay all or a portion of the Purchase Price in shares of Parent Common Stock,
such transaction shall be subject to the satisfaction of each of the following
conditions:


                                       43
<PAGE>   49
         (a) The holders of such shares of Parent Common Stock shall transfer to
Administrator, Parent and/or their Affiliates good, valid and marketable title
to the shares of Parent Common Stock, free and clear of all adverse claims,
security interests, liens, claims, proxies, options, stockholders' agreements
and encumbrances (not including any applicable securities restrictions and
lock-up arrangements with the Parent or any underwriter); and

         (b) The holders of such shares of Parent Common Stock shall make such
representations and warranties as to title to the stock, absences of security
interests, liens, claims, proxies, options, stockholders' agreements and other
encumbrances and other matters as reasonably requested by Administrator, Parent
and/or their Affiliates.

         In the event (i) the Fair Market Value of the Purchase Assets exceeds
net book value of the Purchase Assets, (ii) the Group has utilized commercially
reasonable efforts to obtain financing for such acquisition but is unable to
obtain such financing and (iii) there is either a Material Administrator Default
pursuant to Section 10.3(a) or (c) or a Material Group Default pursuant to
Section 10.4(b) triggering a sale of the Purchase Assets, the Group shall be
entitled to obtain financing from Administrator, Parent and/or their Affiliates,
but only for the difference between the Fair Market Value of the Purchase Assets
and the net book value of the Purchase Assets. The terms of such financing shall
be for a five (5) year period at an interest rate equal to the prime rate (as
published in the Wall Street Journal) plus four percent (4%) or such lesser rate
as is required to be in conformance with all applicable state and federal law.
In the event the Group is entitled to obtain financing from Administrator,
Parent and/or their Affiliates, the Group shall execute and deliver to
Administrator, Parent and/or their Affiliates all such documentation necessary
and appropriate to effectuate the financing transaction including, without
limitation, a secured promissory note, security agreement and financing
statements and such documentation shall contain such representations, warranties
and conditions customary to a secured transaction of this size.

         Section 10.8 Exception to Purchase. Notwithstanding anything contained
herein to the contrary, Administrator, Parent and/or their Affiliates shall not
be obligated to sell the Purchase Assets to the Group as provided in Section
10.6(d)(i) above if the Group is not able to pay the Purchase Price pursuant to
the terms set forth above and assume the Practice Related Liabilities at the
Purchase Closing. In such event, the Group shall surrender the Purchase Assets
to Administrator, Parent and/or their Affiliates as of the Purchase Closing. If
the Practice fails to so surrender the Purchase Assets, Administrator, Parent
and/or their Affiliates may, if permitted by applicable law, without prejudice
to any other remedy which it may have hereunder or otherwise, enter the Premises
and take possession of the Purchase Assets and expel or remove the Group and any
other person who may be occupying the Premises or any part thereof, by force if
necessary, without being liable for prosecution or any claim for damages
therefor.

         Section 10.9 Effect Upon Termination. Upon the Termination Date, except
as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of Administrator, Parent and/or
their Affiliates and the Group under this Agreement shall terminate without
further liability of the Administrator, Parent and/or its their Affiliates to
the Group or the Group to the Administrator, Parent and/or their Affiliates


                                       44
<PAGE>   50
(including, without limitation, any liability for loss of anticipated profits
over the remaining term of this Agreement or from a sale of the Purchase Assets
pursuant to this Article X at less than Fair Market Value), except with respect
to the obligations set forth below. The foregoing to the contrary
notwithstanding:

         (a) Administrator, Parent and/or their Affiliates shall use their best
efforts to cooperate with the Group for the appropriate transfer of management
services.

         (b) Each party hereto shall provide the other party with reasonable
access to books and records owned by it to permit such requesting party to
satisfy reporting and contractual obligations which may be required of it.

         (c) Any other amounts due and owing but unpaid to either Administrator,
Parent and/or their Affiliates or the Group as of the Termination Date shall be
paid promptly by the appropriate party.

         (d) Any and all covenants and obligations of either party hereto which
by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination,
including, without limitation, the obligations of the parties pursuant to the
following Sections: 6.1(b), 6.1(c), 6.1(d), 6.1(e), 6.1(g), 6.2, 6.3, 9.5,
Article VIII and the applicable provisions of Article X and XI.


                                   ARTICLE XI

                               Dispute Resolution

         Section 11.1 Informal Dispute Resolution. In the event of any claim,
controversy, dispute or disagreement between or among the parties hereto which
is not subject to the dispute resolution methodology set forth in Article V
hereof, the parties hereto agree that such other claims, controversies, disputes
or disagreements shall be presented to the Joint Planning Board for hearing and
resolution. In the event the Joint Planning Board is unable to resolve such
matter within a reasonable period following presentation to the Joint Planning
Board, such matter shall be presented to either (a) the Board of Directors of
Parent or (b) a committee designated by the Board of Directors of Parent which
contains at least one (1) physician member. The Board of Directors of Parent or
such committee shall meet within thirty (30) days to attempt to resolve such
claim, controversy, dispute or disagreement.

         Section 11.2 Arbitration. If a claim, controversy, dispute or
disagreement arising out of or relating to this Agreement, which is not subject
to the alternative dispute resolution methodology contained in Article V hereof,
cannot be resolved by the informal means set forth in Section 11.1, the parties
hereto agree that any such claim, controversy, dispute or disagreement between
or among any of the parties shall be governed exclusively by the terms and
provisions of this Article XI; provided, however, that within ten (10) days from
the date which any claim, controversy, dispute or disagreement cannot be
resolved by the informal means


                                       45
<PAGE>   51
set forth in Section 11.1 and prior to commencing an arbitration procedure
pursuant to this Article XI, the parties shall meet to discuss and consider
other alternative dispute resolution procedures other than arbitration,
provided, however that if the parties hereto agree to an alternative to
arbitration they may agree to an alternative set of rules, including rules of
evidence and procedure. If at any time prior to the rendering of the decision by
the arbitrator (or pursuant to such other alternative dispute resolution
procedure) as contemplated in this Article XI to the extent a party makes a
written offer to the other party proposing a settlement of the matter(s) at
issue and such offer is rejected, then the party rejecting such offer shall be
obligated to pay the costs and expenses (excluding the amount of the award
granted under the decision) of the party that offered the settlement from the
date such offer was received by such other party if the decision is for a dollar
amount that is less than the amount of such offer to settle. Notwithstanding the
foregoing, the terms and provisions of this Article XI shall not preclude any
party hereto from seeking, or a court of competent jurisdiction from granting, a
temporary restraining order, temporary injunction or other equitable relief for
any breach of (i) any noncompetition or confidentiality covenant or (ii) any
duty, obligation, covenant, representation or warranty, the breach of which may
cause irreparable harm or damage.

         Section 11.3 Arbitrators. In the event there is a claim, controversy,
dispute or disagreement among Administrator and the Group arising out of or
relating to this Agreement (including any claim based on or arising from an
alleged tort) and the parties hereto have not reached agreement regarding an
alternative to arbitration, the parties agree to select within 30 days of notice
by a party to the other of its desire to seek arbitration under this Article XI
one arbitrator mutually acceptable to Administrator and the Group to hear and
decide all such claims under this Article XI. If such matter or action involves
health-care issues, then the arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators proposed shall be impartial
and independent of all parties. If the parties cannot agree on the selection of
an arbitrator within said 30-day period, then any party may in writing request
the judge of the United States District Court for the Northern District of
California senior in term of service to appoint the arbitrator and, subject to
this Article XI, such arbitrator shall hear all arbitration matters arising
under this Article XI.

         Section 11.4 Applicable Rules.

         (a) Each arbitration hearing shall be held at a place in Santa Clara
County, California acceptable to the arbitrator. The arbitration shall be
conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association to the extent such rules do not conflict with the terms
hereof. The decision of the arbitrator shall be reduced to writing and shall be
binding on the parties and such decision shall contain a concise statement of
the reasons in support of such decision. Judgment upon the award(s) rendered by
the arbitrator may be entered and execution had in any court of competent
jurisdiction or application may be made to such court for a judicial acceptance
of the award and an order of enforcement. The charges and expenses of the
arbitrator shall be shared equally by the parties to the hearing.


                                       46
<PAGE>   52

         (b) The arbitration shall commence within ten (10) days after the
arbitrator is selected in accordance with the provisions of this Article XI. In
fulfilling his duties with respect to determining the amount of any loss, the
arbitrator may consider such matters as, in the opinion of the arbitrator, are
necessary or helpful to make a proper valuation. The arbitrator may consult with
and engage disinterested third parties to advise the arbitrator. The arbitrator
shall not add any interest factor reflecting the time value of money to the
amount of any loss and shall not award any punitive damages.

         (c) If the arbitrator selected hereunder should die, resign or be
unable to perform his or her duties hereunder, the parties, or such senior judge
(or such judge's successor) in the event the parties cannot agree, shall select
a replacement arbitrator. The procedure set forth in this Article XI for
selecting the arbitrator shall be followed from time to time as necessary.

         (d) As to any determination of the amount of any loss, or as to the
resolution of any other claim, controversy, dispute or disagreement, that under
the terms hereof is made subject to arbitration, no lawsuit based on such
claimed loss or such resolution shall be instituted by Administrator, or the
Group, other than to compel arbitration proceedings or enforce the award of the
arbitrator, except as otherwise provided in Section 11.2.

         (e) All privileges under California and federal law, including
attorney-client and work-product privileges, shall be preserved and protected to
the same extent that such privileges would be protected in a federal court
proceeding applying California law.


                                   ARTICLE XII

                               General Provisions

         Section 12.1 Assignment.

         (a) Administrator shall have the right to assign its rights hereunder
to Parent or any direct or indirect wholly-owned subsidiary of Administrator or
Parent (that remains a wholly-owned subsidiary of Administrator or Parent) or to
a financial institution as collateral security for the indebtedness of Parent,
Administrator or their Affiliates without the consent of the Group. No
assignment under subsection (a) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         (b) Administrator, Parent and their Affiliates shall provide notice to
the Group of Administrator's intent (i) to assign this Agreement (other than as
permitted in Section 12.1(a) herein), (ii) sell all or substantially all of the
assets of Administrator or (iii) effectuate a consolidation, merger or sale of a
majority of the capital stock of Administrator as soon as practicable following
a decision by the Parent's and Administrator's respective boards of directors to
seek such assignment or sale. The assignment of this Agreement (other than as

assets of Administrator by Parent or a consolidation, merger or sale of a
majority of the capital stock of Administrator


                                       47

shall not be permitted unless Administrator shall give written notice to the
Group stating the party who made the offer and specifying the purchase price
offered (the "Notice"). The Group shall have the option to repurchase the
Purchase Assets on the same terms and conditions set forth in the Notice. In the
event the Group fails to provide written notice to Administrator of its intent
to exercise its option to repurchase the Purchase Assets pursuant to this
Section 12.1 within the earlier of (i) thirty (30) days or (ii) one-half of the
time during which Administrator, Parent or their Affiliates must respond to an
offer following the Group's receipt of the Notice, the option contained in this
Section 12.1 shall be deemed null and void and of no further force and effect,
and Administrator shall be free to assign the Agreement, sell all or
substantially all of the assets of Administrator or sell or transfer all of the
capital stock Administrator without the consent of the Group. No assignment
under this subsection (b) shall relieve Administrator or Parent of their
obligations hereunder without the consent of the Group.

         Section 12.2 Amendments. This Agreement shall not be modified or
amended except by a written document executed by all parties to this Agreement,
and such written modification(s) or amendment(s) shall be attached hereto.

         Section 12.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

         Section 12.4 Additional Documents. Each of the parties hereto agrees to
execute any document or documents that may be reasonably requested from time to
time by the other party to implement or complete such party's obligations
pursuant to this Agreement.

         Section 12.5 Attorneys' Fees. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover all reasonable attorneys' fees,
costs and expenses including, but not limited to, attorney's fees, costs and
expenses for trial, appellate proceedings and negotiations, in addition to any
other relief granted.

         Section 12.6 Contract Modifications for Prospective Legal Events. In
the event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or independent legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Group and Administrator shall amend this Agreement as necessary
to preserve the underlying economic and financial arrangements between the Group
and Administrator and without substantial economic detriment to either party. If
this Agreement cannot be so amended, the terms of Section 10.3(c) and 10.4(b)
shall apply. To the extent any act or service required of Administrator in this
Agreement should be construed or deemed, by any governmental authority, agency
or court to constitute the practice of medicine, the performance of said act or
service by Administrator shall be deemed waived and forever unenforceable and
the provisions of this Section 12.6 shall be applicable. Neither party shall
claim or assert illegality as a defense to the enforcement of this Agreement or
any provision


                                       48
<PAGE>   54
hereof; instead, any such purported illegality shall be resolved pursuant to the
terms of this Section 12.6 and Section 12.9.

         Section 12.7 Parties In Interest; No Third Party Beneficiaries. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto. Except
as provided in Section 6.1(g), neither this Agreement nor any other agreement
contemplated hereby shall be deemed to confer upon any person not a party hereto
or thereto any rights or remedies hereunder or thereunder.

         Section 12.8 Entire Agreement. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

         Section 12.9 Severability. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 12.10 Governing Law. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULE GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF CALIFORNIA.

         Section 12.11 No Waiver; Remedies Cumulative. No party hereto shall by
any act (except by written instrument pursuant to Section 12.3 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default in or breach of any of the terms
and conditions hereof. No failure to exercise, nor any delay in exercising, on
the part of any party hereto,. any right, power or privilege hereunder shall
operate as a waiver thereof. No single or partial exercise of any right, power
or privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. No remedy set forth in this
Agreement or otherwise conferred upon or reserved to any party shall be
considered exclusive of any other remedy available to any party, but the same
shall be distinct, separate and cumulative and may be exercised from time to
time as often as occasion may arise or as may be deemed expedient.
