               AMERICAN PHYSICIAN PARTNERS, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

       The accompanying consolidated unaudited financial statements have been
prepared by American Physician Partners, Inc. (the "Company" or "APPM") pursuant
to the rules and regulations of the Securities and Exchange Commission, and
reflect all adjustments (all of which are of a normal recurring nature) which,
in the opinion of management, are necessary for a fair statement of the results
of the interim periods presented. These financial statements do not include all
disclosures associated with the annual financial statements and, accordingly,
should be read in conjunction with the attached Management's Discussion and
Analysis of Financial Condition and Results of Operations and the consolidated
financial statements and footnotes for the year ended December 31, 1997,
included in APPM's Form 10-K filed with the Securities and Exchange Commission
on March 31, 1998.

1.   BASIS OF PRESENTATION

      The consolidated financial statements have been prepared on the accrual
basis of accounting and include the accounts of the Company and its wholly-owned
subsidiaries. All intercompany accounts and transactions have been eliminated in
consolidation.

      The Company does not consolidate the operating results and accounts of the
physician practices with which it affiliates (the "Affiliated Practices"). For
display purposes, the Company has presented physician groups revenue and amounts
retained by physician groups in the accompanying consolidated statements of
income to arrive at the Company's service fee revenue.

Service Fee Revenue

      Service fee revenue represents physician groups revenue less amounts
retained by physician groups. The amounts retained by physician groups
represents amounts paid to the physicians pursuant to the service agreements
between the Company and the Affiliated Practices. Under the service agreements,
the Company provides each physician group with the facilities and equipment used
in its medical practice, assumes responsibility for the management of the
operations of the practice, and employs substantially all of the non-physician
personnel utilized by the group.

      The Company's service fee revenues are dependent upon the operating
results of the Affiliated Practices. Where state law allows, service fees due
under the service agreements are derived from two distinct revenue streams: (1)
a negotiated percentage (typically 20% to 30%) of the adjusted professional
revenues as defined in the service agreement; and (2) 100% of the adjusted
technical revenues as defined in the service agreements. In states where the law
requires a flat fee structure, the Company has negotiated a base service fee,
which is equal to the fair market value of the services provided under the
service agreement and which is renegotiated each year to equal the fair market
value of the services provided under the service agreement. The fixed fee
structure should result in the Company receiving substantially the same amount
of service fee as it would have received under its negotiated percentage fee
structure. The service fees received by the Company under either fee structure
provide the Company with a net profits or equivalent interest in the Affiliated
Practices and, as a result, the Company displays the revenues, net of amounts
retained by physicians, and expenses of the Affiliated Practices. Adjusted
professional revenues and adjusted technical revenues are determined by
deducting certain contractually agreed-upon expenses (non-physician salaries and
benefits, rent, depreciation, insurance, interest and other physician costs)
from physician groups revenue.

      Service fee revenue in the first quarter of 1998 consists of the following
(in thousands):

2.   ACQUISITIONS AND PRACTICE AFFILIATIONS

      In January 1998, the Company announced its affiliation with Community
Radiology Associates, Inc., a ten-physician radiology practice based in
Rockville, Maryland. The Company also announced the acquisition of Community
Radiology Associates' seven imaging centers and the acquisition of four
independent imaging centers in the Greater Bay Area of Northern California. The
total consideration for these transactions was approximately $41,133,000
consisting of issuance of (or the obligation to issue) 1,019,018 shares of the
Company's common stock, cash and assumed debt. These transactions will be
accounted for under the purchase method.

3.   EARNINGS PER SHARE

      Net income (loss) per share (basic and diluted) were calculated using the
weighted average number of common shares outstanding during the period plus the
net additional number of shares which would be issuable upon the exercise of
stock options, assuming the Company used the proceeds received to purchase
additional shares at market value. The Company adopted Statement of Financial
Accounting Standards No. 128 ("SFAS 128"), "Earnings per Share," effective
December 15, 1997. SFAS 128 requires that the calculation of basic earnings per
share be calculated by dividing net income by the weighted average number of
shares of common stock outstanding during the period and diluted earnings per
common share be calculated using the weighted average number of shares of common
stock and common stock equivalents. As required, the Company reported earnings
per share in accordance with SFAS 128.

4.   SUBSEQUENT EVENTS

      In April 1998, the Company announced its affiliation with Radiology
Imaging Associates, Inc., an eight-physician radiology practice based in Fort
Pierce, Florida. The total consideration for this transaction was approximately
$11,800,000 consisting of the issuance of 433,662 shares of the Company's common
stock, cash and assumed debt. This transaction will be accounted for under the
purchase method.

ITEM 2.           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
                  AND RESULTS OF OPERATIONS (DOLLARS IN THOUSANDS)

         The following discussion of the results of operations and financial
condition of the Company should be read in conjunction with the Company's
consolidated financial statements and notes thereto included in the Annual
Report on Form 10-K for the year ended December 31, 1997, and with the
consolidated financial statements included in this Form 10-Q.

OVERVIEW

         American Physician Partners, Inc. ("APPM" or the "Company") is a
leading provider of physician practice management services to radiology
practices. The Company's focus is on the development, consolidation and
management of integrated radiology and imaging center networks. As of May 12,
1998, APPM provided management services to nine Affiliated Practices consisting
of 241 physicians practicing at 47 hospitals and 70 owned, operated or managed
diagnostic imaging centers ("ICs") in California, Florida, Kansas, Maryland, New
York and Texas. The Company provides Affiliated Practices with the 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.

RESULTS OF OPERATIONS

Three Months Ended March 31, 1998

      The Company conducted no significant operations before its initial public
offering ("IPO") in November 1997 when the Company acquired the tangible and
intangible non-medical assets and certain liabilities, and entered into service
agreements with seven radiology practices (the "Founding Affiliated Practices").
The acquisitions that occurred simultaneously with the IPO are referred to 
herein as the "Reorganizations". As a result, the Company's comparative 
first-quarter 1997 results are not meaningful.

Service Fee Revenue

      The Company generated service fee revenue of $29,716 for the three months
ended March 31, 1998. There was no service fee revenue generated during the same
period ended March 31, 1997.

Salaries and Benefits

      Salaries and benefits for the three months ended March 31, 1998, were
$9,368. Salaries and benefits include certain costs of non-physician clinical
employee expenses paid by the Company pursuant to the terms of the service
agreements. The percentage of salaries and benefits to total service fee revenue
was 31.5% for the three months ended March 31, 1998.

Practice Supplies

      Practice supplies expenses for the three months ended March 31, 1998, were
$2,186. Practice supplies expenses include costs of film, contrast and other 
related supplies paid by the Company pursuant to the terms of the service
agreements. The percentage of practice supplies expenses to total service fee
revenue was 7.4% for the three months ended March 31, 1998.

Practice Rent and Lease Expense

      Practice rent and lease expenses for the three months ended March 31,
1998, were $2,360. Practice rent and lease expenses include costs of the
facilities used to provide the medical services and lease costs for equipment
used in the performance of certain medical procedures. The percentage of
practice rent and lease expenses to total service fee revenue was 7.9% for the
three months ended March 31, 1998. 



                                       6
<PAGE>   9

Other Practice Expenses

      Other practice expenses for the three months ended March 31, 1998, were
$5,343. Other practice expenses include all other costs associated with the
maintenance and continued operation of the Affiliated Practices. The percentage
of other practice expenses to total service fee revenue was 18.0% for the three
months ended March 31, 1998.

Corporate General and Administrative

      Corporate general and administrative expenses for the three months ended
March 31, 1998, were $2,010 compared to $844 for the three months ended March
31, 1997 representing an increase of $1,166 or 138.2%. The percentage of
corporate general and administrative expenses to total service fee revenue was
6.8% for the three months ended March 31, 1998. Corporate general and
administrative expenses increased due to the continued building of the Company's
infrastructure prior to and following its IPO.

Depreciation and Amortization

      Depreciation and amortization expenses for the three months ended March
31, 1998, were $2,472 compared to $4 for the three months ended March 31, 1997
representing an increase of $2,468. The percentage of depreciation and
amortization expenses to total service fee revenue was 8.3% for the three months
ended March 31, 1998. Depreciation and amortization expenses increased from the
1997 amount due to the Reorganizations and the subsequent acquisitions completed
in the first quarter of 1998.

Interest Expense

      Interest expense for the three months ended March 31, 1998, was $1,400
compared to $32 for the three months ended March 31, 1997 representing an
increase of $1,368. The percentage of interest expense to total service fee
revenue was 4.7% for the three months ended March 31, 1998. Interest expense
increased due the cost of borrowings under the Company's $115 million credit
facility (the "Credit Facility") entered into on November 26, 1997, the 
assumption of certain indebtedness of the Founding Affiliated Practices in
connection with the Reorganizations and certain capital lease obligations.

Income Taxes

      Income taxes were provided on the taxable income of the Company for
federal and state reporting purposes using the applicable effective rates. The
Company did not recognize any income tax benefit for the operating losses
incurred in prior periods. The Company will recognize these benefits in future
periods.

Net Income

     As a result of the foregoing factors, the Company generated a net income of
$3,073 for the three months ended March 31, 1998, or diluted income per share of
$0.16 on 18,841,000 shares outstanding, compared to a net loss of $880 for the
three months ended March 31, 1997, or diluted loss per share of $(0.44) on
2,000,000 shares outstanding.

Three Months Ended March 31, 1997

      Prior to November 26, 1997, the Company had no revenue while incurring
corporate overhead expenses associated with building its management
infrastructure. As a result, the Company's comparative first-quarter 1997
results are not meaningful.

Liquidity and Capital Resources

      Net cash from operations for the three months ended March 31, 1998, was
$359. Net cash from operations includes a use of cash in the amount of $3,400
for deferred income taxes as a result of the conversion of the Founding
Affiliated Practices from cash basis to accrual basis. The Company files a
consolidated annual return on the accrual basis. The 



                                       7
<PAGE>   10

Company also experienced an increase in its accounts receivable due to the time
required to obtain new Medicare provider numbers for several of the Founding
Affiliated Practices. The Company was successful in obtaining the required
provider numbers in the latter half of the first quarter.

      Net cash used in investing activities for the three months ended March 31,
1998, was $27,893. During the three months ended March 31,1998, the Company
expended $26,054 in consideration for acquisitions. These expenditures were
funded primarily from borrowings under the Company's Credit Facility.

      Net cash flows from financing activities for the three months ended March
31, 1998, were $29,895. Borrowings during the three months ended March 31,
1998, under the Credit Facility were $30,800 and were used to finance the 
Company's ongoing development activities, the acquisition of equipment and for
working capital purposes.

      Under the terms of the Credit Facility dated November 26, 1997, the
Company may borrow, repay and reborrow amounts during the first three years of
the Credit Facility. Amounts outstanding under the Credit Facility at the end of
three years are required to be repaid in quarterly installments of varying
amounts commencing September 30, 2000. The Credit Facility expires and all loans
thereunder mature on the sixth anniversary of the closing date of the Credit
Facility. Borrowings under the Credit Facility at any time may not exceed the
lesser of $115.0 million or 2.75 times the consolidated EBITDA of the Company
giving pro forma effect to acquisitions made with such borrowings. At March 31,
1998, the Company was eligible to borrow up to $115.0 million under the Credit
Facility, and the Company had outstanding borrowings of $80.4 million under the
Credit Facility. At the Company's option, the interest rate is (i) an adjusted
LIBOR rate plus an applicable margin which can vary from 1.0% to 1.75% dependent
on certain financial ratios or (ii) the prime rate plus an applicable margin
which can vary from 0% to 0.75%. In each case the applicable margin varies based
on financial ratios maintained by the Company. The Credit Facility includes
certain restrictive covenants including prohibitions on the payment of dividends
and the maintenance of certain financial ratios (including minimum debt-service
coverage and maximum debt-to-EBITDA coverage, as defined). Borrowings under the
Credit Facility are secured by all service agreements of which the Company is or
becomes a party and a pledge of the stock of the Company's subsidiaries.
Approximately $21.5 million of borrowings under the Credit Facility were used to
pay a portion of the cash portion due pursuant to the Reorganizations.

      On April 13, 1998, the Company announced that it planned to make a private
offering of $100.0 million aggregate principal amount of Senior Subordinated
Notes Due 2008 (the "Notes") to certain initial purchasers who will resell the
Notes in reliance on the exemption from registration contained in Rule 144A
under the Securities Act of 1933, as amended.

      On May 12, 1998, the Company announced that it received a firm commitment
from its existing group of lenders to increase its Credit Facility to $160 
million from the current $115 million. Closing is conditioned upon execution of
an amended credit agreement, which is anticipated before the end of May 1998. As
a result, the Company has elected not to pursue the previously announced private
offering of Notes.

      The Company anticipates that funds generated from operations, cash and
cash equivalents, and funds available under the Credit Facility will be
sufficient to meet the Company's working capital requirements and debt
obligations and to finance any necessary capital expenditures at least through
the end of 1998. Expansion of the Company's business through acquisitions may
require additional funds, which, to the extent not provided by
internally-generated sources, cash, and the Credit Facility, would require the
Company to seek additional debt or equity financing.

the assumptions described in this report underlying such forward-looking
statements. Actual results and developments could differ materially from those
expressed in or implied by such statements due to a number of factors,

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company's exposure to market risk for changes in interest rates
relates primarily to the Company's cash equivalents and its Credit Facility.

                           PART II: OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

      The Company is a party to one suit relating to services provided by a
Founding Affiliated Practice. There can be no assurances that additional claims
will not be asserted against the Company in the future. The Company became
subject to certain pending claims as the result of successor liability in
connection with the acquisition of the Founding Affiliated Practices; 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.

      There can be no assurance that the Company will not subsequently be named
as a defendant in additional lawsuits. Each existing Affiliated Practice has
retained responsibility for, and agreed to indemnify the Company in full
against, the liabilities associated with these lawsuits. In the event the
Company is subsequently added as a party in any of these lawsuits, or a monetary
judgment is entered against the Company and indemnification is unavailable for
any reason, the Company's business, financial condition and results of
operations could be materially adversely affected.

                            determined based on the average closing sale price
                            of the APPM Stock for the twenty (20) trading days
                            prior to the Closing Date.

pursuant to Article XIV hereof.

       The exercise by Buyer or APPM, in good faith, of Buyer's or APPM's right

determination pursuant to Section 4.1(c) that any shares of APPM Stock
deposited with APPM are to be retained by APPM, including without limitation
the rights to vote such shares and receive distributions thereon and the
obligations to pay all taxes, assessments, and charges with respect thereto

dispose of such shares is limited and subject to all applicable laws relating
to sales of securities); provided, however, that any distribution, on or with
respect to such shares and any other shares or securities into which such

       Section 5.14  Contracts and Commitments.

              (a)    Schedule 5.14 contains a true, accurate and complete list,
and Seller has delivered to APPM true and complete copies, of each contract,
agreement and other instrument (other than insurance contracts identified in
Schedule 5.24 or Lease Agreements identified in Schedule 5.20) to which Seller

including, without limitation, (i) all agreements between Seller, on the one

the other hand, 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 acquisitions involving an amount of $75,000 in any fiscal year or $75,000 in

of Seller (or any Physician Employee of Seller) to compete in any line of

as noted in Schedule 5.14, there are no contracts, agreements or other
instruments to which Seller 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 Buyer of the
Purchased Assets, or which could inhibit or prevent Seller from transferring to
or vesting in Buyer good and sufficient title to the Purchased Assets.  For
each of the Assumed Liabilities, in every instance where consent is necessary,
Seller obtained and delivered to Buyer in writing, effective as of the date
hereof, such consents as are necessary to effect a valid and binding transfer
or assignment so as to enable Buyer to enjoy all of the rights now enjoyed by
Seller under such contracts.  Notwithstanding the foregoing, Seller shall not
transfer to Buyer any contracts or agreements relating to the provision of
professional medical services or other such agreements and contracts that Buyer
consents to in writing to be retained by Seller.  Except as set forth in
Schedule 5.14, no contract with a health care provider or Payor has been
materially amended or terminated within the last twelve (12) months.

              (b)    Except as disclosed in Schedule 5.14, (i) Seller has not
received notice of any plan or intention of any other party to exercise any
right to cancel or terminate such contract, agreement or instrument, and Seller
is not aware of any fact(s) that would justify the exercise of such a right;
and (ii) Seller 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.

the subject of an audit, investigation, enforcement action or other similar

              (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 could
result, directly or indirectly, (including through any obligation of
indemnification or contribution), in any taxes, penalties or other liability to
Seller, APPM or any of their respective Affiliates.

              (e)    Claims and Litigation.  Except as set forth in Schedule

knowledge of Seller and each Principal 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 have been threatened that
could result in the revocation of any such favorable determination letter or
ruling.

              (g)    Funding Status.  Except as set forth in Schedule 5.19(g),
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 Seller is a member (a
"Controlled Group").  Except as set forth in Schedule 5.19(g), 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.  Schedule 5.19(g) contains a

Plan which has been subject to Title IV of ERISA or Section 412 of the Code.

              (j)    PBGC.  No facts or circumstances exist that would result
in the imposition of liability against APPM, Buyer or any of its Affiliates by
the Pension Benefit Guaranty Corporation ("PBGC") as a result of any act or
omission by Seller 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.  Seller 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.  Except as set forth in
Schedule 5.19(l), neither Seller nor any Principal Stockholder or Physician
Employee of Seller 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 Seller.

       Section 5.20  Lease Agreements.  Schedule 5.20 contains a true, accurate
and complete list of all the lease agreements and license agreements to which
Seller or any Seller Subsidiary is a party and pursuant to which Seller or any
Seller 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 $10,000 per year (the
"Lease Agreements").  Seller has delivered to Buyer 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 Seller or any Seller Subsidiary
(as applicable) or event of material default or event which with notice or





                                       18
<PAGE>   25
lapse of time, or both, would constitute a material default by Seller or any
Seller Subsidiary (as applicable) and, individually or in the aggregate, result
in a Material Adverse Effect on Seller; or (ii) any existing material default
by any other party under any of the Lease Agreements or, to the knowledge of
Seller, 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, neither Seller nor any Principal Stockholder has received
notice of any pending or threatened reassessment of any property covered by the
Lease Agreements.  Seller or a Seller Subsidiary (as applicable) has obtained
the consent of each landlord or lessor whose consent is required to the
assignment of the Lease Agreements and has delivered to Buyer in writing such
consents as are necessary to effect a valid and binding transfer or assignment
of Seller's or any Seller Subsidiary's rights thereunder.  Seller has a good,
clear, valid and enforceable leasehold interest under each of the Lease
Agreements.  The Lease Agreements are in compliance with all applicable safe
harbor provisions promulgated by the Department of Health and Human Services in
connection with the enforcement of the federal Fraud and Abuse Statute, 42 CFR
Part 1001 and any similar applicable state law safe harbor or other exemption
provisions.

limitation, all the property and assets reflected in Seller 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).  Seller Financial Statements reflect all personal
property used in connection with the operation of the business subject to
disposition in the ordinary course of business and such personal property are
the necessary assets to continue operation of Seller and any Seller Subsidiary.

       Section 5.22  Environmental Matters.

              (a)    Neither Seller nor any Seller Subsidiary has, within the

entity, or any other Person, any written notice, demand, citation, summons,
complaint or order or any notice of any penalty, lien or assessment, and no
investigation or review is pending by any governmental entity, with respect to
any (i) alleged violation by Seller of any Environmental Law (as defined in

defined in subsection (e) below) for Seller under any applicable Environmental
Law that had, or could likely have, a Material Adverse Effect on Seller.
Neither Seller nor any Seller Subsidiary has engaged in any activity or failed
to undertake any activity which action or failure to act has given, or could
likely give, rise to any Environmental Liabilities or enforcement action by any
federal, state or local regulatory agency or authority, or has resulted,





                                       19
<PAGE>   26
or could likely result, in any fine or penalty imposed pursuant to any
Environmental Law.  Schedule 5.22(b) discloses any known presence of asbestos
in or on Seller's or any Seller Subsidiary's owned or leased premises.  There
is no friable asbestos in or on Seller's or any Seller Subsidiary's owned or
leased premises.

              (c)    No soil or water in or under any assets currently or

has received any notice or other 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 the Principal
Stockholders, no such cancellation or increase of deductibles, retainages or

any Affiliate thereof has filed a written application for any professional
liability insurance coverage which has been denied by an insurance agency or
carrier.  Schedule 5.24 also sets forth a list of all claims under any
Insurance Policy in excess of $10,000 per occurrence filed by Seller or any

practicing the same type of medicine in the same geographic area.

       Section 5.25  Accounts Receivable; Payors.

              (a)    Attached hereto as Schedule 5.25(a) is a list and aging of
all accounts receivable of Seller as of December 15, 1997, which list is

list of the names and addresses of each Payor including, but not limited to,
all private-pay patients as a single Payor, of Seller which accounted for more

payment submitted to any such party.

thereto (calculated consistent with past practice), of items of a quality and a
quantity usable and saleable in the ordinary course of Seller's business and
conform to generally accepted standards in the industry of which Seller is a
part.  The value of the inventories reflected on Seller Current Balance Sheet
contained in Seller Financial Statements are net of adequate reserves for
damaged, excess, and unusable items.  Purchase commitments of Seller 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.

permits, registrations, qualifications and other rights and authorizations
required by law, ordinance, regulation or ruling of any governmental regulatory
authority necessary to operate its/his/her business and (ii) is certified for
participation under Titles XVIII and XIX of the Social Security Act (the
"Medicare and Medicaid Programs") (Medicare and Medicaid Programs and such
other similar federal, state or local reimbursement or governmental programs

Programs and with such private non-governmental programs (including without
limitation any private insurance program) under which Seller is presently
receiving payments directly or indirectly from any Payor for patient care (such
non-governmental programs herein referred to as "Private Programs").  A true,
correct and complete list of such licenses, permits and other authorizations,
and provider agreements, is set forth in Schedule 5.28(a), true, complete and
correct copies of which have been provided to APPM.  No violation, default,
order or deficiency exists with respect to any of the items listed in Schedule
5.28(a) except for such violations, defaults, orders or deficiencies which
would not be reasonably likely to have a Material Adverse Effect on Seller, and
there is no action pending or recommended by any state or federal agencies
having jurisdiction over the items listed in Schedule 5.28(a), either to
revoke, withdraw or suspend any material license or to terminate the
participation of Seller 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 Schedule 5.28(a) or to revoke, withdraw or suspend
any material license to operate its business as is presently being conducted by
it.  To the knowledge of Seller, there has been no decision not to renew any
existing agreement with any provider or Payor relating to Seller's business as
presently being conducted by it.  Except as set forth in Schedule 5.28(a) or
Schedule 5.12 hereof, neither Seller 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

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.  Except as set forth and described in Schedule 5.29, 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 license suspended or revoked by any governmental regulatory authority or
agency, hospital, integrated delivery system,  trade association, professional

disagreements with respect to any such agreement.

              (c)    Seller owns or has the legal right to use the Proprietary

all Damages asserted against or incurred by such Seller Indemnities arising out

              (b)    all Assumed Liabilities.

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

              (a)    A party claiming indemnification under this Agreement (an
"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 the party from 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.  Except as set forth in Section 14.6, the failure to promptly
deliver a Claim Notice shall not relieve the Indemnifying Party of its
obligations to the 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 (i) whether the Indemnifying Party disputes its potential liability to
the Indemnified Party under this Article XIV with respect to such Third Party
Claim; and (ii) whether the Indemnifying Party desires, at the sole cost and
expense of the Indemnifying Party, to defend the Indemnified Party against such
Third Party Claim.





                                       31
<PAGE>   39
              (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 its sole cost and expense, 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).  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 (it being understood and agreed that if an Indemnified Party
takes any such action that is prejudicial and causes a final adjudication that
is adverse to the Indemnifying Party, the Indemnifying Party shall be relieved
of its obligations hereunder with respect to such Third Party Claim).  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 its 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.

              (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 its 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





                                       32
<PAGE>   40
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 an 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 an
Indemnifying Party pursuant to Section 14.3(d) shall be made within 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)    Notwithstanding any provision herein to the contrary, the
obligation of APPM or Buyer, on the one hand, or Seller or any Principal
Stockholder, on the other hand, to provide indemnification for breach of any
representation or warranty as provided in Section 14.1(a) or Section 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 APPM or Buyer, on the
one hand, or Seller, on the other hand, as a result of such a breach or
breaches exceeds $10,000.00, and then such Indemnifying Party shall indemnify
the Indemnified Party to the full amount of such Damages.

              (g)    Notwithstanding any provision herein to the contrary, the
Principal Stockholders shall not have any liability to Buyer or APPM under this
Agreement after the Principal Stockholders have, collectively, paid to Buyer or
APPM pursuant to this Article XIV indemnification payments in an aggregate
amount (together with the applicable value (as determined pursuant to Section
14(c)) of any APPM Shares retained by APPM pursuant to Section 4.1(c)), equal
to $_______________.

       Section 14.4  Remedies Not Exclusive.

              (a)    The Buyer Indemnitees' rights to be indemnified, defended
and held harmless by Seller and the Principal Stockholders shall be the Buyer
Indemnitees' exclusive remedy against Seller and the Principal Stockholders for
matters arising out of this Agreement; provided, however, that the limitation
set forth in this sentence shall not limit any Buyer Indemnitee's remedies
against Seller and the Principal





                                       33
<PAGE>   41
Stockholders for matters arising out of this Agreement that constitute fraud or
intentional misrepresentation by any Seller or Principal Stockholder, failure
of any Seller or Principal Stockholder to deliver to Buyer or APPM good, valid
and marketable title to the Purchased Assets, or failure of any Seller or
Principal Stockholder to pay any taxes or any penalties, assessments or
interest relating thereto.  This Section shall not limit APPM's right to
injunctive relief against a breach by any Seller or Principal Stockholder of
any covenant set forth in this Agreement.

              (b)    The Seller Indemnitees' rights to be indemnified, defended
and held harmless by Buyer and APPM shall be the Seller Indemnitees' exclusive
remedy against Buyer and APPM for matters arising out of this Agreement;
provided, however, that the limitation set forth in this sentence shall not
limit any Seller Indemnitee's remedies against Buyer or APPM for matters
arising out of this Agreement that constitute fraud or intentional
misrepresentation by Buyer or APPM.  This Section shall not limit Seller's
right to injunctive relief against a breach by APPM or Buyer of any covenant
set forth in this Agreement.

              (c)    Except as set forth in Sections 14.4(a) or 14.4(b) above,
the remedies provided in this Agreement shall not be exclusive of any other
rights or remedies available to one party against the other, either at law or
in equity.

       Section 14.5  No Effect on Liability.  None of (i) the consummation of
the transactions contemplated by this Agreement or the Other Agreements, (ii)
the delay or omission of any party to exercise any of its rights under this
Agreement or any Other Agreement or (iii) any investigation or disclosure that
any party makes, any notice that any party gives, or any knowledge that any
party obtains as a result thereof, or otherwise, shall (A) affect the liability
of the parties to one another for breaches of this Agreement, any Other
Agreement or any related agreement between the parties hereto, or (B) prevent
any party from relying on the representations or warranties contained in this
Agreement, any Other Agreement or any related agreement between the parties
hereto.

       Section 14.6  Commencing Actions.  Any action against any party hereto
that is not commenced on or before the second anniversary of the Closing Date
shall be deemed waived, and no person shall have any remedy against any party
therefor; provided, however, that actions by Buyer or APPM against any Seller
or Principal Stockholder may be commenced at any time with respect to actions
(i) that constitute fraud or intentional misrepresentation by any Seller or
Principal Stockholder;  (ii) that result from the failure of any Seller or
Principal Stockholder to pay any taxes or any penalties, assessments or
interest thereon; (iii) that result from the failure of any Seller or Principal
Stockholder to deliver to Buyer or APPM good, valid and marketable title to the
Purchased Assets; or (iv) that result from any breach of Section 5.22 or
Section 5.13 or any misrepresentation relating to the representations and
warranties set forth therein.

       Section 14.7  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 14.8  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 XVI
                   NONDISCLOSURE OF CONFIDENTIAL INFORMATION

       Section 16.1  Non-Disclosure Covenant.  Seller recognizes and
acknowledges that it has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APPM that is
valuable, special and unique assets of APPM's businesses.  Seller shall not
disclose such Confidential Information to any person, firm, corporation,
association or other entity for any purpose or reason whatsoever, unless (i)
such information becomes available to or known by the public generally through
no fault of Seller; (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), Seller shall, if possible, give
prior written notice thereof to APPM and provide APPM with the opportunity to
contest such disclosure; or (iii) the disclosing party reasonably believes that
such disclosure is required by applicable law in connection with the defense of
a lawsuit against the disclosing party.  In the event of a breach or threatened
breach by Seller of the provisions of this Section, APPM 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 APPM 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, Seller agrees that, in the event of a breach by it of
the foregoing covenant, the covenant may be enforced against it by injunctions
and restraining orders.

       Section 16.3  Survival.  The obligations of Seller under this Article
XVI shall survive the consummation of the transactions as described in 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 APPM to
a wholly owned subsidiary of APPM, provided that any such assignment shall not
relieve APPM 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.  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, covenants and undertakings contained herein
shall survive the consummation of the transactions described herein and all
statements contained in any certificate, exhibit or other instrument delivered
by or on behalf of Seller, any Principal Stockholder, APPM or Buyer pursuant to
this Agreement shall be deemed to have been representations and warranties by
such Seller, such Principal Stockholder, APPM or Buyer.

       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 MARYLAND.

       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 Reference to Agreement.  Use of the words "herein,"
"hereof," "hereto" and the like in this Agreement shall be construed as
references to this Agreement as a whole and not to any particular Article,
Section or provision of this Agreement, unless otherwise noted.

       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 APPM has
determined in its good faith judgment 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 APPM in connection with conducting an examination of the
operations and assets of Seller; provided that APPM shall reasonably promptly
provide notice of any release.

       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,
facsimile or courier service, when actually received by the party to whom
notice is sent; or (ii) if delivered by mail

operations and changes in financial position for the periods then ended,
subject to normal year-end adjustments (the effect of which will not
individually or in the aggregate result in a Material Adverse Effect on Seller)
and lack of footnotes thereto.

       Section 5.11  No Undisclosed Liabilities.  Except as listed in Schedule
5.11 hereto, Seller does not have any liabilities or obligations of any nature,
whether known or unknown and whether accrued, absolute, contingent or

condition, (financial or otherwise), or results of operations or the prospects
of Seller, the Business or the Centers which (i) if successful, may,
individually or in the aggregate, have a Material Adverse Effect on Seller, the
Business or the Centers or (ii) could adversely affect the ability of Seller to
effect the transactions contemplated hereby, and there is no basis for any such
action or any state of facts or occurrence of any event which might give rise
to the foregoing.  There are no unsatisfied judgments against Seller or any
licensed professional or other individual affiliated with Seller relating to
services provided on behalf of Seller or any consent decrees to which any of
the foregoing is subject.  Except as set forth in Schedule 5.12, each of the
matters, if any, set forth in Schedule 5.12 is fully covered by policies of

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 reasonably, individually or in the
aggregate, would not have a Material Adverse Effect on Seller.

       Section 5.14  Contracts and Commitments.

              (a)    Schedule 5.14 contains a true, accurate and complete list,
and Seller has delivered to APP true and complete copies, of each contract,
agreement and other instrument (other than insurance contracts identified in
Schedule 5.24 or Lease Agreements identified in Schedule 5.20 to which Seller
is a party or by which it or any of its properties or assets are bound
including, without limitation, (i) all agreements between Seller, 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, 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
Seller to make, or setting forth conditions under which Seller would be
required to make, aggregate future payments in excess of $5,000 in any fiscal
year or $10,000 in the aggregate, (iii) all agreements for capital improvements
or acquisitions involving an amount of $5,000 in any fiscal year or $10,000 in
the aggregate, (iv) all agreements containing a covenant limiting the freedom
of Seller (or any provider employee of Seller) to compete in any line of
business with any person or entity or in any geographic area or (v) all written
contracts and commitments to which aggregate future payments by Seller in
excess of $5,000 in any fiscal year or $10,000 in the aggregate and that are
not cancelable by providing notice of sixty (60) days or less.  Except as noted
in Schedule 5.24, 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, each constituting an
Assumed Contract will continue to be binding in accordance with their terms
after consummation of the transaction contemplated herein; except as noted in
Schedule 5.24, there are no contracts, agreements or other instruments to which
Seller 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 Buyer of the Purchased Assets, or which
could inhibit or prevent Seller from transferring to or vesting in Buyer good
and sufficient title to the Purchased Assets.  For each of the Assumed
Liabilities, in every instance where consent is necessary, Seller shall, on or
before the Closing Date, obtain and deliver to Buyer in writing, effective as
of the Closing Date, such consents as are necessary to effect a valid and
binding transfer or assignment so as to enable Buyer to enjoy all of the rights
now enjoyed by Seller under such contracts.  Said consent shall be in a form
acceptable to Buyer and shall contain an acknowledgment by the consenting party
that Seller has fully complied with and is not in default under any provision
of the particular contract or agreement.  Notwithstanding the foregoing, Seller
shall not transfer to Buyer any contracts or agreements relating to the
provision of professional medical services or other such agreements and
contracts that Buyer consents to in writing to be retained by Seller.  Except
as set forth in Schedule 5.14, no contract with a health care provider or Payor
has been materially amended or terminated within the last twelve (12) months.

received notice of any plan or intention of any other party to exercise any
right to cancel or terminate such contract, agreement or instrument, and Seller
is not aware of any fact(s) that would justify the exercise of such a right;
and (ii) Seller 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 5.15  No Brokers.  Seller has not entered into and will not
enter into any agreement, arrangement or understanding with any person or firm
which will result in the obligation of Buyer to pay any finder's fee, brokerage
commission or similar payment.

<PAGE>   19
       Section 5.16  No Other Agreements to Sell the Assets of the Seller's
Business.  Seller does not have any legal obligation, absolute or contingent,
to any other individual or entity to sell any of the Purchased Assets (other
than agreements for the sale of Inventory in the ordinary course), or to effect
any sale of the Centers or to enter into any agreement with respect thereto.

       Section 5.17  Employee Matters.

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

Section 3.1 of ERISA) of or pertaining to Seller and any of its present or
former employees, or any predecessors in interest.

              (b)  Employees.  As of December 15, 1997, Seller employed a

combined salary, benefits and bonuses in 1997 in excess of $25,000.  Seller is
not delinquent in payment to any of its employees or Physician Employees for
wages, salaries, bonuses or other direct compensation for any services

purchase of the Centers pursuant hereto;

              (b)    There is no unfair labor practice, charge or complaint or
any other employment-related matter against or involving Seller pending or

discrimination (including discrimination based upon sex, age, marital status,
race, national origin, the making of workers' compensation claims, sexual
preference, handicap or veteran status) pending or threatened before the Equal
Employment Opportunity Commission or any federal, state or local agency or
court against Seller.  There have been no governmental audits of the equal
employment opportunity practices of Seller and no basis for any such audit
exists which, if conducted would result in a Material Adverse Effect on Seller;

              (d)    Except as set forth in Schedule 5.18(d), there are no
inquiries, investigations or monitoring activities of any licensed, registered,
or certified professional personnel employed or retained by, credentialed or
privileged, or otherwise affiliated with Seller pending or threatened by any
state professional board or agency charged with regulating the professional
activities of health care practitioners.

              (a)    Identification.  Schedule 5.19 contains a complete and
accurate list of all employee benefit plans (within the meaning of Section 3(3)
of ERISA) sponsored by Seller or to which Seller 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").  Seller has provided to Buyer copies of all

Seller has provided or made available to Buyer a written description of all
existing practices engaged in by Seller that constitute Employee Benefit Plans.
Except as set forth in Schedule 5.19(a) subject to the requirements of ERISA,
each of the Employee Benefit Plans can be terminated or amended at will by
Seller without any further liability or obligation on the part of such entity
to make further contributions or payments in connection therewith following
such termination.  Except as set forth in Schedule 5.19(a), 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.  Except as set forth in Schedule 5.19(c),
Seller has not received any notice that any Employee Benefit Plan is currently
the subject of an audit, investigation, enforcement action or other similar

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 could
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.  Except as set forth in Schedule

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 Seller and each Stockholder, has been

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.  Schedule 5.19(g) contains 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.

<PAGE>   21
              (i)    Multiemployer Plans.  Neither Seller 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 exist that would result
in the imposition of liability against APP, Buyer or any of its Affiliates by
the Pension Benefit Guaranty Corporation ("PBGC") as a result of any act or
omission by Seller 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.  Seller has no obligation or commitment to

Seller 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 Seller.

       Section 5.20  Lease Agreements.  Schedule 5.20 contains a true, accurate
and complete list of all the lease agreements and license agreements to which
Seller is a party and pursuant to which Seller leases (whether as lessor or
lessee) or licenses (whether as licensor or licensee) any real or personal
property related to the operation of the Centers and which requires payments in
excess of $10,000 per year (the "Lease Agreements").  Seller has delivered to
Buyer 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 Seller or event of material default or event which with notice or
lapse of time, or both, would constitute a material default by Seller and,
individually or in the aggregate, may reasonably result in a Material Adverse
Effect on the Centers, or (ii) any existing material default by any other party
under any of the Lease Agreements or, to the knowledge of Seller, 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.  There is no pending or
threatened reassessment of any property covered by the Lease Agreements.
Seller has obtained the consent of each landlord or lessor whose consent is
required to the assignment of the Lease Agreements and has delivered to Buyer
in writing such consents as are necessary to effect a valid and binding
transfer or assignment of Seller's rights thereunder.  Seller has a good,
clear, valid and enforceable leasehold interest under each of the Lease
Agreements.  The Lease Agreements are in compliance with all applicable safe

Part 1001 and any similar applicable state law safe harbor or other exemption
provisions.

does not own interest (other than the Lease Agreements) in real property.

                     (ii)   Except as set forth in Schedule 5.3, Seller (i) has
good and marketable title to all of its properties and assets (real, personal

       Section 5.23  Filing Reports.  All returns, reports, plans and filings
of any kind or nature necessary to be filed by Seller 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 Seller.

       Section 5.24  Insurance Policies.  Schedule 5.24 lists and briefly
describes Seller's policies of insurance to which Seller or any Affiliate is a
party or under which Seller or any Affiliate, 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 Seller or any of its Affiliates
(the "Insurance Policies").  Except as set forth in Schedule 5.24, all of the
Insurance Policies are issued by insurers that are financially sound and
reputable, and 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 are currently paid.  All Insurance Policies
currently maintained by Seller or any Affiliate thereof ("Current Policies")
taken together, (i) provide adequate insurance coverage for the assets,
properties and operations of Seller and its Affiliates for all risks normally
insured against by a Person carrying on a substantially similar business or
businesses as Seller and its Affiliates, (ii) are sufficient for compliance
with legal and contractual requirements to which Seller 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.  Except as set forth in Schedule 5.24, neither Seller nor any of its
Affiliates nor any officer or director thereof has received any notice or other
communication from any issuer of any Current Policy canceling 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 Stockholders, no such cancellation or increase of
deductibles, retainages or premiums is threatened.  Except as set forth in
Schedule 5.24, there are no outstanding claims, settlements or premiums owed
against any Insurance Policy, and all have been given and all potential or
actual claims under any Insurance Policy have been presented in due and timely
fashion.  Except as set forth in Schedule 5.24, since January 1, 1993, neither
Seller nor any Affiliate thereof has filed a written application for any
professional liability insurance coverage which has been denied by an insurance
agency or carrier.  Schedule 5.24 also sets forth a list of all claims under
any Insurance Policy in excess of $10,000 per occurrence filed by Seller or any
Affiliate thereof during the immediately preceding three-year period.

       Section 5.25  Accounts Receivable; Payors.

              (a)    Attached hereto as Schedule 5.25(a) is a list and aging of
all accounts receivable of Seller as of November 30, 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,
collectible in the ordinary course of business, net of reserves for doubtful
and uncollectible accounts shown in Seller Financial Statements or on the
accounting records of Seller (which reserves are adequate and calculated
consistent with past practice).  Notwithstanding the foregoing, nothing shall
be construed hereunder as a guarantee by Seller of the collectibility of the
accounts receivable.

              (b)    Schedule 5.25(b) sets forth a true, correct and complete
list of the names and addresses of each Payor including, but not limited to,
all private-pay patients as a single Payor, of Seller which accounted for more
than 5% of the revenues of Seller in the fiscal year ended December 31, 1996,
or which is reasonably expected to account for more than 5% of the revenues of
Seller for the fiscal year to end December 31, 1997.  Except as set forth in
Schedule 5.25(b), Seller has satisfactory relations with such Payors and none
of such Payors has notified Seller that it intends to discontinue its
relationship with Seller or to deny any payments due from, or any claims for
payment submitted to any such party.

       Section 5.26  Accounts Payable; Suppliers.  Intentionally omitted.

       Section 5.27  Inventory.  All items of inventory on Seller Current
Balance Sheet contained in Seller 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





                                       17
<PAGE>   24
ordinary course of Seller's business and conform to generally accepted
standards in the industry of which Seller is a part.  The value of the
inventories reflected on Seller Current Balance Sheet contained in Seller
Financial Statements are net of adequate reserves for damaged, excess, and
unusable items.  Purchase commitments of Seller 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 5.28  Licenses, Authorization and Provider Programs.

other licensed employee or independent contractor of Seller, other than any

registrations, qualifications and other rights and authorizations required by
law, ordinance, regulation or ruling of any governmental regulatory authority
necessary to operate the Business and (ii) is certified for participation under
Titles XVIII and XIX of the Social Security Act (the "Medicare and Medicaid
Programs") (Medicare and Medicaid Programs and such other similar federal,
state or local reimbursement or governmental programs for which Seller is
eligible are hereinafter referred to collectively as the "Governmental
Programs") and has current provider numbers for such Governmental Programs and
with such private non-governmental programs (including without limitation any
private insurance program) under which Seller is presently receiving payments
directly or indirectly from any Payor for patient care (such non-governmental
programs herein referred to as "Private Programs").  A true, correct and
complete list of such licenses, permits and other authorizations, and provider
agreements, is set forth in Schedule 5.28(a), 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 Schedule 5.28(a) except for
such violations, defaults, orders or deficiencies which would not be reasonably
likely to have a Material Adverse Effect on Seller, and there is no action
pending or recommended by any state or federal agencies having jurisdiction
over the items listed in Schedule 5.28(a), either to revoke, withdraw or
suspend any material license or to terminate the participation of Seller 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
Schedule 5.28(a) or to revoke, withdraw or suspend any material license to
operate its business as is presently being conducted by it.  To the knowledge
of Seller, there has been no decision not to renew any existing agreement with
any provider or Payor relating to the Centers as presently being conducted by
it.  Except as set forth in Schedule 5.28(a) or Schedule 5.12 hereof, neither
Seller nor either Center (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,

disciplined by any licensing board, state agency, regulatory body or authority,
hospital, Payor or specialty board, or (iii) has had a final judgment or
settlement entered against him/her/its in connection with a malpractice or
similar action.

              (b)    Except as set forth in Schedule 5.28(b), neither Seller
nor the Centers have been 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 5.29  Inspections and Investigations.  Neither the right of
Seller, the Centers, nor the right of any licensed professional or other
individual affiliated with Seller 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.  Except as set forth and described in Schedule 5.29, no licensed
professional or other individual affiliated with the Centers has, during the
past three (3) years prior to the Effective Time, had their license suspended
or revoked by any governmental regulatory authority or agency, hospital,
integrated delivery system,  trade association, professional review
organization, accrediting organization or certifying agency.  True, correct and
complete copies of all reports, correspondence, notices and other documents
relating to any matter described or referenced in Schedule 5.29 have been
provided to Buyer.

effect to any Material Adverse Effect qualifier contained as part of any such
representation or warranty) of Seller contained herein or in any Schedule or
certificate delivered hereunder;





                                       24
<PAGE>   31
              (b)  any violation (or alleged violation) by Seller and/or any of

forming a part thereof, or any amendment thereof or supplement thereto),
arising out of or based upon any omission or alleged omission to state therein
a material fact relating to Seller (including its Subsidiaries) required to be
stated therein or necessary to make the statements therein not misleading.

       APP and Buyer hereby agree to seek indemnification hereunder in the
following priority:  (1) Parent and (2) Principal Stockholders.

       Section 14.2  Indemnification by APP and Buyer.  Subject to the terms
and conditions of this Article XIV, APP and Buyer jointly and severally hereby
agree to indemnify, defend and hold Seller and its respective agents, attorneys
and Affiliates harmless from and against all Damages asserted against or
incurred by such indemnities arising out of or resulting from a breach by APP
or Buyer of any representation, warranty or covenant (without giving effect to
any Material Adverse Effect qualifier contained as part of any such
representation or warranty) of APP or Buyer contained herein or in any schedule
or certificate delivered hereunder.

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

              (a)    A party claiming indemnification under this 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 from 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.  Except as set forth in Section 14.6, the failure to promptly
deliver a Claim Notice shall not relieve the Indemnifying Party of its
obligations to the 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 (i) whether the Indemnifying Party disputes its potential liability to
the Indemnified Party under this Article XIV with respect to such Third Party
Claim and (ii) whether the Indemnifying Party desires, at the sole cost and
expense of the 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 its sole cost and expense, 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).  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





                                       25
<PAGE>   32
Indemnifying Party (it being understood and agreed that if an Indemnified Party
takes any such action that is prejudicial and causes a final adjudication that
is adverse to the Indemnifying Party, the Indemnifying Party shall be relieved
of its obligations hereunder with respect to such Third Party Claim).  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 its 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.

              (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 its 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 an 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 an
Indemnifying Party pursuant to Section 14.3(d) shall be made within 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)    Notwithstanding any provision herein to the contrary, the
obligation of APP or Buyer on the one hand, or Seller or the Principal
Stockholders, on the other hand, to provide indemnification for breach of any
representation or warranty as provided in Section 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 APP or Buyer, on the one hand, or
Seller or the Principal Stockholders, on the other hand, as a result of such a
breach or breaches exceeds $15,000.

       Section 14.4  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 14.5  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 14.6  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.

                                  TERMINATION

                             Intentionally Omitted.


                                  ARTICLE XVI

                   NONDISCLOSURE OF CONFIDENTIAL INFORMATION

       Section 16.1  Non-Disclosure Covenant.  Seller and each Principal
Stockholder recognize and acknowledge that it 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 unique assets of APP's businesses.  APP
and Buyer acknowledge that they had in the past, currently have, and in the
future may possibly have, access to certain Confidential Information of Seller
that is valuable, special and unique assets of Seller's business.  Seller, and
Principal Stockholder and APP 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 and (b) to counsel and other advisers to APP 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 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) Seller or APP, as the case may be, shall, if possible, give
prior written notice thereof to Seller and APP and provide Seller and 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





                                       27
<PAGE>   34
is the sole and exclusive owner of such Confidential Information as a result of
the Acquisition or otherwise.  In the event of a breach or threatened breach by
Seller or APP of the provisions of this Section, APP and Seller 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 APP and Seller 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 and Seller agree that, in the event of a breach
by any 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.

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 with respect to the Parent for a period of two (2) years, and with
respect to the Principal Stockholders for a period of one (1) year from the

pursuant to this Agreement shall be deemed to have been representations and
warranties by such Seller, such Principal Stockholder, APP or Buyer and,
notwithstanding any provision in this Agreement to the contrary, the
representations and warranties contained herein shall survive the Closing for
the periods of time set forth in this Section 17.6.

     Section 5.14    Contracts and Commitments.

             (a)     Schedule 5.14 attached hereto contains a true, accurate
and complete list, and Seller has delivered to APP true and complete copies, of
each contract, agreement and other instrument (other than insurance contracts
identified in Schedule 5.24 or Lease Agreements identified in Schedule 5.20 to

bound including, without limitation, (i) all agreements between Seller, on the

provider, on the other hand, 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

requiring Seller to make, or setting forth conditions under which Seller would
be required to make, aggregate future payments in excess of $5,000 in any
fiscal year or $10,000 in the aggregate, (iii) all agreements for capital
improvements or acquisitions involving an amount of $5,000 in any fiscal year

written contracts and commitments to which aggregate future payments by Seller

after consummation of the transaction contemplated herein; except as noted in
Schedule 5.24, there are no contracts, agreements or other instruments to which
Seller 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 Buyer of the Purchased Assets, or which
could inhibit or prevent Seller from transferring to or vesting in Buyer good
and sufficient title to the Purchased Assets.  For each of the Assumed
Liabilities, in every instance where consent is necessary, Seller shall, on or
before the Closing Date, obtain and deliver to Buyer in writing, effective as
of the Closing Date, such consents as are necessary to effect a valid and
binding transfer or assignment so as to enable Buyer to enjoy all of the rights
now enjoyed by Seller under such contracts.  Said consent shall be in a form
acceptable to Buyer and shall contain an acknowledgment by the consenting party
that Seller has fully complied with and is not in default under any provision
of the particular contract or agreement.  Notwithstanding the foregoing, Seller
shall not transfer to Buyer any contracts or agreements relating to the
provision of professional medical services or other such agreements and
contracts that Buyer consents to in writing to be retained by Seller.  Except
as set forth in Schedule 5.14, no contract with a health care provider or Payor

received notice of any plan or intention of any other party to exercise any
right to cancel or terminate such contract, agreement or instrument, and Seller
is not aware of any fact(s) that would justify the exercise of such a right;
and (ii) Seller 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 5.15    No Brokers.  Seller has not entered into and will not
enter into any agreement, arrangement or understanding with any person or firm
which will result in the obligation of Buyer to pay any finder's fee, brokerage
commission or similar payment.

Business.  Seller does not have any legal obligation, absolute or contingent,
to any other individual or entity to sell any of the Purchased Assets (other
than agreements for the sale of Inventory in the ordinary course), or to effect
any sale of the Centers or to enter into any agreement with respect thereto.

present or former employees, or any predecessors in interest.

             (b)     Employees.  As of December 15, 1997, Seller employed a
collective total of one (1) part-time and two (2) full-time employees.

combined salary, benefits and bonuses for 1996 in excess of $25,000 or who is
expected to receive combined salary, benefits and bonuses in 1997 in excess of
$25,000.  Seller 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

based upon sex, age, marital status, race, national origin, the making of
workers' compensation claims, sexual preference, handicap or veteran status)
pending or threatened before the Equal Employment Opportunity Commission or any
federal, state or local agency or court against Seller.  There have been no
governmental audits of the equal employment opportunity practices of Seller and
no basis for any such audit exists which, if conducted would result in a
Material Adverse Effect on Seller; and

             (d)     There are no inquiries, investigations or monitoring
activities of any licensed, registered, or certified professional personnel
employed or retained by, credentialed or privileged, or otherwise affiliated

attached hereto, Seller has not received any notice that any Employee Benefit
Plan is currently the subject of an audit, investigation, enforcement action or

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.

(within the meaning of Section 4043 of ERISA) for which the notice requirement

             (k)     Retirees.  Seller has no obligation or commitment to

of $10,000 per year (the "Lease Agreements").  Seller has delivered to Buyer
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
Seller [or any Seller 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 Seller or any Seller Subsidiary (as applicable) and,

disposition in the ordinary course of business and such personal property are
the necessary assets to continue operation of Seller and any Seller Subsidiary.

(e) below) for Seller under any applicable Environmental Law that had, or could
likely have, a Material Adverse Effect on Seller.  Neither Seller nor any
Seller Subsidiary has engaged in any activity or failed to undertake any
activity which action or failure to act has given, or could likely give, rise

local regulatory agency or authority, or has resulted, or could likely result,

5.22(b) attached hereto discloses any known presence of asbestos in or on

friable asbestos in or on Seller's or any Seller Subsidiary's owned or leased

Affiliate is a party or under which Seller or any Affiliate, 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 Seller
or any of its Affiliates (the "Insurance Policies").  Except as set forth in
Schedule 5.24, all of the Insurance Policies are issued by insurers that are
financially sound and reputable, and 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 are currently paid.
All Insurance Policies currently maintained by Seller or any Affiliate thereof

Affiliates nor any officer or director thereof has received any notice or other
communication from any issuer of any Current Policy canceling 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 the Stockholders, no such cancellation or increase
of deductibles, retainages or premiums is threatened.  Except as set forth in
Schedule 5.24, there are no outstanding claims, settlements or premiums owed
against any Insurance Policy, and all have been given and all potential or
actual claims under any Insurance Policy have been presented in due and timely
fashion.  Except as set forth in Schedule 5.24, since January 1, 1993, neither
Seller nor any Affiliate thereof has filed a written application for any
professional liability insurance coverage which has been denied by an insurance
agency or carrier.  Schedule 5.24 also sets forth a list of all claims under
any Insurance Policy in excess of $10,000 per occurrence filed by Seller or any
Affiliate thereof during the immediately preceding three-year period.

all accounts receivable of Seller as of December 15, 1997, which list is

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,
collectible in the ordinary course of business, net of reserves for doubtful
and uncollectible accounts shown in Seller Financial Statements or on the
accounting records of Seller (which reserves are adequate and calculated
consistent with past practice).  Nothing contained in this Section 5.25 shall
be construed as a guarantee of collectibility of the accounts receivable.

would not be reasonably likely to have a Material Adverse Effect on Seller, and
there is no action pending or recommended by any state or federal agencies
having jurisdiction over the items listed in Schedule 5.28(a), either to
revoke, withdraw or suspend any material license or to terminate the
participation of Seller in any Governmental Program or Private Program, and no

would constitute grounds for a violation, order or deficiency with respect to
any of the items listed in Schedule 5.28(a) or to revoke, withdraw or suspend
any material license to operate its business as is presently being conducted by
it.  To the knowledge of Seller, there has been no decision not to renew any

APP is a party or by which APP or any of its respective properties are bound.

                                    REMEDIES


     Section 13.1    Indemnification by Seller and the Principal Stockholders.
Subject to the terms and conditions of this Article XIV, Seller and the
Principal Stockholders jointly and severally agree to indemnify, defend and
hold APP and Buyer and their respective directors, officers, members, managers,
employees, agents, attorneys and Affiliates harmless from and against all
losses, claims,  obligations, demands, assessments, penalties, liabilities,
costs, damages, reasonable attorneys' fees and expenses (collectively,
"Damages") asserted against or incurred by such indemnities arising out of or
resulting from:

             (a)     a breach of any representation or warranty (without giving
effect to any Material Adverse Effect qualifier contained as part of any such
representation or warranty) of Seller contained herein or in any Schedule or
certificate delivered hereunder; and

             (b)     any violation (or alleged violation) by Seller and/or any
of its past or present directors, officers, partners, shareholders, employees,
agents, consultants and Affiliates of state or federal laws governing health
care fraud and abuse (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.

     Section 13.2    Indemnification by APP and Buyer.  Subject to the terms
and conditions of this Article XIV, APP and Buyer jointly and severally hereby
agree to indemnify, defend and hold Seller and its respective agents, attorneys
and Affiliates harmless from and against all Damages asserted against or
incurred by such indemnities arising out of or resulting from (a) a breach by
APP or Buyer of any representation or warranty (without giving effect to any
Material Adverse Effect qualifier contained as part of any such representation
or warranty) of APP or Buyer contained herein or in any schedule or certificate
delivered hereunder.

     Section 13.3    Conditions of Indemnification.  All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

             (a)     A party claiming indemnification under this 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 from whom indemnification is sought (the "Indemnifying
Party") of any third-party claim or claims asserted against the Indemnified
Party ("Third Party Claim") that





                                       25
<PAGE>   31
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.  Except as set forth
in Section 14.3 attached hereto, the failure to promptly deliver a Claim Notice
shall not relieve the Indemnifying Party of its obligations to the 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.
Damages awarded shall be reduced by the costs incurred as a result of such
delays.

                     Within thirty (30) days after receipt of any Claim Notice
(the "Election Period"), the Indemnifying Party shall notify the Indemnified
Party (i) whether the Indemnifying Party disputes its potential liability to
the Indemnified Party under this Article XIV with respect to such Third Party
Claim and (ii) whether the Indemnifying Party desires, at the sole cost and
expense of the 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 its sole cost and expense, 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).  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 (it being understood and agreed that if an Indemnified Party
takes any such action that is prejudicial and causes a final adjudication that
is adverse to the Indemnifying Party, the Indemnifying Party shall be relieved
of its obligations hereunder with respect to such Third Party Claim).  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 its 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.

             (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





                                       26
<PAGE>   32
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes its
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 an 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 an
Indemnifying Party pursuant to Section 14.3(d) shall be made within 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)     Notwithstanding any provision herein to the contrary, the
obligation of APP or Buyer on the one hand, or Seller or the Principal
Stockholders, on the other hand, to provide indemnification for breach of any
representation or warranty as provided in Section 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 APP or Buyer, on the one hand, or
Seller or the Principal Stockholders, on the other hand, as a result of such a
breach or breaches exceeds $10,000.

     Section 13.4    Remedies Exclusive.  The remedies provided in this
Agreement shall be 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 13.5    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 13.6    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





                                       27
<PAGE>   33
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.

that they will not disclose such Confidential Information to any person, firm,

becomes available to or known by the public generally through no fault of
Seller or APP, as the case may be, (ii) disclosure is required by law or the

disclosing any information pursuant to this clause (ii) Seller or APP, as the
case may be, shall, if possible, give prior written notice thereof to Seller
and APP and provide Seller and 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 Acquisition or otherwise.  In the
event of a breach or threatened breach by Seller or APP of the provisions of
this Section, APP and Seller 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 APP
and Seller from pursuing any other available remedy for such breach or
threatened breach, including the recovery of damages.

     Section 15.2    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 and Seller agree that, in the event of a breach
by any of them of the foregoing covenant, the covenant may be enforced against
them by injunctions and restraining orders.

     Section 15.3    Survival.  The obligations of the parties under this
Article XVI shall survive the termination of this Agreement.

                                  ARTICLE XVI

writing, and signed by the parties hereto.  The waiver of any of the terms and

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 16.6    Survival of Representations, Warranties and Covenants.
The representations, warranties and covenants contained herein shall survive

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

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 conducting an examination of the

are not intended to create any partnership, joint venture, agency or employment

       Section 2.2   Practice of Medicine.  The parties hereto acknowledge that
neither Administrator nor Parent is authorized or qualified to engage in any
activity which may be construed or deemed to constitute the practice of
medicine and that nothing herein shall be construed as the practice of medicine

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

parties hereby agree that the benefits to the Group hereunder do not require,

                     (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
Professional Revenues and/or Technical Revenues into the Deposit Account, any
withdrawal of any funds from the Deposit

<PAGE>   16
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.

       (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
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 in the state of
Maryland (unless the Group shall consent to the transfer of such records to
another state, which consent shall not be unreasonably withheld) 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

shall be and remain the sole property of the Group.





                                       12
<PAGE>   18
              (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.  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

interest, refinancing expenses, depreciation, loss on disposition of assets,

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 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





                                       14
<PAGE>   20
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 expenditures and improvements at or for
the benefit of the Practice in excess of either $50,000 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 $100,000 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.





                                       15
<PAGE>   21
       (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, 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





                                       16
<PAGE>   22
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





                                       17
<PAGE>   23
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.





                                       18
<PAGE>   24
       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

       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





                                       21

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 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 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.

(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 including, but not limited to, 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 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





                                       29
<PAGE>   35
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 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 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   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





                                       30
<PAGE>   36
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 6.7   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





                                       31
<PAGE>   37
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 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;





                                       32
<PAGE>   38
       (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 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 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





                                       34
<PAGE>   40
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,
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 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.





                                       36
<PAGE>   42
       (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 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





                                       37
<PAGE>   43
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 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,





                                       38
<PAGE>   44
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 in connection with the Practice or otherwise
resulting from the Acquisition, (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 (ii) 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).





                                       39
<PAGE>   45
       (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 at the fair market
value immediately prior to the Purchase Closing), or some combination of cash
and Parent Common Stock equal to the Purchase Price and (b) assume the Practice
Related Liabilities.  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.

       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.

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:

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

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), 6.2, 6.3,
9.5, Article VIII and the applicable provisions of Article X and 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.

                               General Provisions

       Section 12.1  Assignment.

       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.

       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.

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

       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
