     The following summary is qualified in its entirety by the more detailed
information and financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. Simultaneously with the closing of this offering,
American Physician Partners, Inc. ("APPI") will acquire certain tangible and
intangible assets, and assume certain liabilities, of seven radiology practices
located in California, Kansas, Maryland, New York and Texas (each radiology
practice, a "Founding Affiliated Practice" and, collectively, the "Founding
Affiliated Practices") in exchange for cash and shares of its Common Stock (each
a "Reorganization" and, collectively, the "Reorganizations"). As used herein,
"Affiliated Practices" refers to the Founding Affiliated Practices and such
additional radiology practices, management service organizations, diagnostic
imaging centers and other related businesses that the Company may acquire in the
future. Unless otherwise indicated, all references to "APPI" mean American
Physician Partners, Inc. prior to the consummation of the Reorganizations and
references herein to the "Company" include APPI and its subsidiaries.
 
                                  THE COMPANY
 
     The Company was formed in April 1996 to provide practice management
services to radiology practices with a focus on the development, consolidation
and management of integrated radiology and imaging center networks. Upon
completion of this offering, the Company will provide practice management
services to seven radiology practices consisting of 223 physicians practicing at
42 hospitals and 65 diagnostic imaging centers ("ICs") in California, Kansas,
Maryland, New York and Texas. The Company will derive its revenue from service
fees in exchange for the provision of management, administrative, technical and
other non-medical services to the Affiliated Practices.
 
     Radiology services in the United States are delivered through a fragmented
system of local providers, including small to medium-sized groups of diagnostic
and interventional radiologists and radiation oncologists. According to a 1995
report prepared by SMG Marketing Group, total spending on diagnostic imaging
services is estimated at $56 to $70 billion annually. According to the American
College of Radiology, approximately 27,000 radiologists were actively involved
in patient care in the United States in 1996, practicing in more than 3,200
groups with a typical size of six radiologists per group.
 
     Cost-containment pressures on health care providers have placed small to
medium-sized physician groups at a competitive disadvantage, since their
practices typically have relatively high operating costs and often lack the
capital, information systems and management expertise necessary to provide both
high-quality and cost-effective medical care. To remain competitive, physician
practices are seeking to affiliate with larger organizations that manage the
non-medical aspects of their practices and provide access to greater capital
resources, more efficient cost structures and more favorable relationships with
payors. The Company believes that an integrated network of radiologists and
facilities offering a comprehensive array of radiology services can provide
significant advantages to patients, physicians, hospitals and payors.
 
     The Founding Affiliated Practices provide a wide range of diagnostic and
therapeutic services, including x-ray and fluoroscopy, magnetic resonance
imaging, computed tomography, mammography, ultrasound, nuclear medicine,
radiation oncology and interventional radiology. The Founding Affiliated
Practices were selected based on a variety of factors, including: physician and
practice credentials and reputation; competitive market position; subspecialty
mix of physicians; historical financial performance and growth potential; and
willingness to embrace the Company's vision and philosophy regarding the
provision of radiology services. The Company intends to provide Affiliated
Practices with the necessary capital resources and expertise to invest in new
technologies, complete consolidating acquisitions, implement sophisticated
management information systems, promote efficient practice patterns, develop
coordinated marketing efforts and realize purchasing economies of scale.
 
     The Company's objective is to develop integrated networks of radiology
groups and ICs that can provide wide geographic coverage and subspecialty
expertise. The Company intends to provide the networks with sophisticated
management, state-of-the-art information systems and appropriate capital for
expansion. The Company's strategy is to (i) emphasize quality service, (ii)
expand within its selected markets, (iii) improve
                                        3
<PAGE>   5
 
operating efficiencies within the Affiliated Practices and (iv) expand into new
regional markets through acquisitions of or affiliations with additional
radiology practices and ICs.
 
                              THE REORGANIZATIONS
 
   
     Simultaneously with the closing of this offering, the Company will acquire
certain tangible and intangible non-medical assets (i.e., assets other than
patient records, payor contracts and provider contracts) and liabilities of the
Founding Affiliated Practices (including interests in imaging center joint
ventures with third-parties) in connection with the Reorganizations.
Substantially all of the proceeds of this offering will be used to fund the cash
portion of the consideration to be paid for the non-medical assets of the
Founding Affiliated Practices and to repay approximately $12.2 million of
indebtedness assumed in connection with the Reorganizations. See "Use of
Proceeds." Upon consummation of the Reorganizations, the Company will enter into
long-term service agreements (the "Service Agreements") with the Founding
Affiliated Practices pursuant to which the Company will provide management,
administrative, technical, and non-medical business services (including the
provision of facilities, equipment and non-medical personnel) to the Founding
Affiliated Practices in exchange for a service fee.
    
 
   
     The Service Agreements have a 40-year term, subject to earlier termination
under certain circumstances. The service fees represent physician groups
revenue, net less amounts retained by physician groups. Physician groups
revenue, net consists of the revenue of the Affiliated Practices reported at the
estimated realizable amounts from patients, third-party payors and others for
services rendered, net of contractual and other adjustments. The service fees
payable to the Company by the Affiliated Practices under the Service Agreements
vary based on the fair market value, as determined in arms' length negotiations,
and the nature and extent of services provided. Where state law allows, the
service fees due under the Service Agreements are derived from two distinct
revenue streams: (i) the Affiliated Practice pays a service fee based on a
negotiated percentage (Founding Affiliated Practice service fees range from 20%
to 25%) of the adjusted professional revenues as defined in the Service
Agreement; and (ii) the Affiliated Practice pays a service fee based on 100% of
the adjusted technical revenues as defined in the Service Agreement, which
equals the fair value of the services provided. 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. 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 non-physician costs) from physician
groups revenue of the Affiliated Practice. In addition, the Company receives
income from joint ventures in which the Affiliated Practices hold ownership
interests. Physician compensation is determined by the Affiliated Practices
pursuant to employment arrangements between the Affiliated Practice and the
individual physicians. See "Business -- Service Agreements." The Company does
not participate in the negotiation of physician employment arrangements.
Pursuant to the terms of the Service Agreements, the Founding Affiliated
Practices will continue to provide professional radiological services and will
maintain full control over the provision of professional radiological services.
The Company will not engage in the practice of medicine or provide professional
radiological services. As a result of the Reorganizations and upon completion of
this offering, the Founding Affiliated Practices and certain officers and
directors of the Company will own approximately 70.6% of the outstanding shares
of Common Stock. See "Certain Transactions -- Reorganizations" and "Principal
Stockholders."
    
                         ------------------------------
 
   
     The Underwriters have reserved $5.0 million of shares of the Common Stock
offered hereby to offer to GE Capital at the initial public offering price.
    
 
     Prior to this offering and consummation of the Reorganizations, the Company
has not conducted any significant operations. The Company's principal offices
are located at 2301 NationsBank Plaza, 901 Main Street, Dallas, Texas 75202, and
its telephone number at that address is (214) 761-3100.

Stock at a conversion price of $8.00 per share (assuming an initial public
offering price of at least $14.00 per share).

                             SUMMARY FINANCIAL DATA
              (IN THOUSANDS, EXCEPT STATEMENT OF OPERATIONS DATA)
 
   
     Upon the completion of this offering and pursuant to the Reorganizations,
the Company will acquire certain assets and liabilities of, and enter into the
Service Agreements with, the Founding Affiliated Practices. Due to the fact that
the Company has had no significant operations to date, no pro forma statement of
operations has been included in this Prospectus. The amount and composition of
costs to be incurred by the Company related to the provision of management
services to the Founding Affiliated Practices may differ from the costs
historically incurred by the Founding Affiliated Practices; therefore, the costs
presented in the individual financial statements of the Founding Affiliated
Practices may not be representative of the Company's costs on a pro forma basis.
The following pro forma as adjusted balance sheet data gives effect to the
Reorganizations, the conversion of the Convertible Notes, borrowings of
approximately $13.6 million under the Credit Facility to refinance substantially
all funded debt previously incurred by the Founding Affiliated Practices, the
completion of this offering and the application of the estimated net proceeds
therefrom as if they had occurred on June 30, 1997 (all assuming a public
offering price of $15.00 per share). Since APPI and the Founding Affiliated
Practices were not under common control or management as of June 30, 1997, the
pro forma as adjusted balance sheet data is not necessarily indicative of the
financial position that would have been achieved had these events actually
occurred on such date. The following financial data should be read in
conjunction with the information set forth under "Use of Proceeds," "American
Physician Partners, Inc. Unaudited Pro Forma Combined Balance Sheet" and
"Selected Financial Data" and in the historical financial statements of APPI and
the Founding Affiliated Practices included elsewhere herein.

                                  RISK FACTORS
 
   
     In addition to the other information contained in this Prospectus,
prospective investors should consider carefully the factors listed below in
evaluating an investment in the shares of Common Stock offered hereby. This
Prospectus contains forward-looking statements that include risks and
uncertainties, and address, among other things, acquisition and expansion
strategy, use of proceeds, projected capital expenditures, liquidity, possible
third-party payor arrangements, cost reduction strategies, integration of the
Affiliated Practices, possible effects of changes in government regulation and
managed care and availability of insurance. These statements may be found under
"Prospectus Summary," "Risk Factors," "Use of Proceeds," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business" and elsewhere in this Prospectus. Actual events or results may differ
materially from those discussed in forward-looking statements as a result of
various factors, including, without limitation, those discussed in the risk
factors set forth below and matters set forth elsewhere in this Prospectus.
    
 
ABSENCE OF COMBINED OPERATING HISTORY; NO PRIOR OPERATING EXPERIENCE
 
     APPI was incorporated in April 1996, has generated no revenue to date and
has conducted no significant operations other than in connection with this
offering and the pending Reorganizations. The Company will derive a substantial
portion of its revenue from service fees it receives from the Affiliated
Practices for managing certain non-medical aspects of their operations. The
service fees paid to the Company generally will be based on the revenue of the
Affiliated Practices. The Company's success will depend in large part on its
ability to apply its management experience and implement practices, systems and
marketing plans to enhance the revenue and profitability of the Affiliated
Practices. To date, the Founding Affiliated Practices have been operated as
independent entities without common management. Moreover, the Company has no
preexisting relationship with any of the Founding Affiliated Practices and has
not managed any physician groups in the past. Due to this lack of prior
operating experience, there can be no assurance that the Company will be able to
integrate successfully the assets and personnel of the Founding Affiliated
Practices or to successfully implement its operating strategies with and
profitably provide management and administrative services to the Founding
Affiliated Practices or any other Affiliated Practices. There can be no
assurance that the Company will be profitable on a quarterly or annual basis in
the future.
 
DEPENDENCE ON AFFILIATED RADIOLOGISTS; RISK OF TERMINATION OF SERVICE AGREEMENTS
 
   
     The Company's operations are entirely dependent on its continued
affiliation through Service Agreements with the Founding Affiliated Practices
and any other practices with which it may affiliate in the future. There can be
no assurance that the Founding Affiliated Practices or any other Affiliated
Practices will operate profitably or that the Service Agreements will not be
terminated. Two of the Founding Affiliated Practices (Advanced Radiology, LLC
and The Ide Group, P.C.) are expected to contribute in the aggregate
approximately 50% of the service fees to be paid to the Company by the Founding
Affiliated Practices, based on their historical net patient revenue and
expenses. The Service Agreements with the Founding Affiliated Practices will
have terms of 40 years, but may be terminated by either party if (i) the other
party (a) files a petition in bankruptcy or other similar events occur or (b)
defaults in the performance of a material duty or obligation, which default
continues for a specified period after notice or (ii) an opinion is rendered by
a law firm of nationally-recognized expertise in health care law that a material
term of the Service Agreement is in violation of applicable law (or a court or
regulatory agency finds as such) and such violation cannot be cured. The Company
generates its revenue through the service fees it receives pursuant to the
Service Agreements. The termination of any of the Founding Affiliated Practices'
Service Agreements could have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business --
Service Agreements." The Company anticipates that, to the extent that it enters
into management relationships with additional practices, the Service Agreements
entered into with such Affiliated Practices will have provisions providing for
the terms, termination and repurchase of assets similar to those contained in
the Service Agreements with the Founding Affiliated Practices. Any termination
of the Service Agreements with such Affiliated Practices could have a material
adverse effect on the Company's business, financial condition and results of
operations. In addition, the Company has executed a $115 million credit facility
(the "Credit
    
 
                                        7
<PAGE>   9
 
   
Facility") with GE Capital and other lenders and granted a security interest in
the Service Agreements to the lenders to secure the Company's payment and
performance obligations under the Credit Facility. The Credit Facility is
expected to become effective upon completion of this offering and consummation
of the Reorganizations. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources" and
"Business -- Service Agreements."
    
 
     Each Founding Affiliated Practice will enter into employment agreements
with the key radiologists associated with each such Founding Affiliated
Practice. The employment agreements generally will be for a term of five years.
Although the Company, in conjunction with the Founding Affiliated Practices,
will endeavor to maintain and renew such contracts, in the event a significant
number of such radiologists terminate their relationships with the Company, the
Company's business could be adversely affected. The Company anticipates that, to
the extent it enters into Service Agreements with other Affiliated Practices,
similar employment agreements will be entered into between such Affiliated
Practices and the key radiologists associated with their respective practices;
as such, the Company will face similar risks if a significant number of such
radiologists terminate their relationships with the Affiliated Practices.
Further, if a significant number of radiologists or other medical service
providers become unable or unwilling to continue in their roles, the Company's
business could be adversely affected. Neither the Company nor the Founding
Affiliated Practices maintains insurance on the lives of any affiliated
physician for the benefit of the Company. See "Business -- Affiliation
Structure."
 
UNCERTAINTY REGARDING THE ENFORCEABILITY OF NONCOMPETITION PROVISIONS
 
     The Service Agreements require the Founding Affiliated Practices to enter
into and enforce agreements with the stockholders and full-time radiologists at
each Founding Affiliated Practice (subject to certain exceptions) that include
covenants not to compete with the Company for a period of two years after
termination of employment. See "Business -- Service Agreements." The Company
anticipates that Service Agreements that may be entered into with Affiliated
Practices in the future will also contain similar covenants requiring such
Affiliated Practices to restrict the ability of the stockholders and full-time
radiologists at such Affiliated Practices to compete with the Company. In most
states, a covenant not to compete will be enforced only to the extent it is
necessary to protect a legitimate business interest of the party seeking
enforcement, does not unreasonably restrain the party against whom enforcement
is sought and is not contrary to public interest. This determination is made
based on all of the facts and circumstances of the specific case at the time
enforcement is sought. For this reason, it is not possible to predict with
certainty whether a court will enforce such a covenant in a given situation. In
addition, the Company is not aware of any judicial precedents which have
addressed whether a management company's interest under a management agreement
will be viewed as the type of protectable business interest that would permit it
to enforce such a covenant. The inability of the Company to enforce such
anti-competition covenants could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
RELIANCE ON REFERRALS
 
   
     The Company is dependent on referrals from third parties to its owned,
operated or managed ICs and to other ICs or hospitals to which the Affiliated
Practices provide professional services in each of the markets where the Company
conducts business. A substantial portion of these referrals are made by
physicians who have no contractual obligation or economic incentive to refer
patients to those ICs or hospitals. The Company's owned, operated or managed ICs
and the Founding Affiliated Practices compete with local radiologists and
technical imaging service providers, including non-profit and for profit
hospitals and health systems. The Company generates revenue from fees charged
for technical services provided at its owned, operated or managed ICs and from
service fees that it receives from the Affiliated Practices. Neither the Company
nor any Founding Affiliated Practice is dependent on any single referral source
for a material portion of its revenue. If a sufficiently large number of
physicians elected at any time to discontinue referring patients to the ICs
affiliated with the Company, the Company's business, financial condition and
results of operations would be materially adversely affected. In addition, there
is potential for disruption of relationships in connection with the acquisition
or assumption of control of a particular IC by the Company, and there can be
    
 
                                        8
<PAGE>   10
 
no assurance that the Company will retain all of the business conducted by that
IC at the time of acquisition or assumption of control by the Company.
 
     Further, in an effort to control costs, non-governmental health care payors
have implemented cost containment programs which could limit the ability of
physicians to refer patients to the Company's owned, operated or managed ICs.
For example, persons enrolled in prepaid health care plans, such as health
maintenance organizations ("HMOs"), often are not free to choose where they
obtain diagnostic imaging, interventional radiology or radiation oncology
services. Rather, the health plan provides these services directly or contracts
with providers and requires its enrollees to obtain such services only from such
providers. Some insurance companies and self-insured employers also limit such
services to contracted providers. Such "closed panel" systems are now common in
the managed care environment. Other systems create an economic disincentive for
referrals to providers outside of the plan's designated panel of providers.
Although the Company intends to seek managed care contracts for its owned,
operated or managed ICs and to assist the Affiliated Practices to obtain
contracts to provide professional and technical radiology services, there can be
no assurance that the Company will be able to compete successfully for managed
care contracts against larger companies with greater resources.
 
RISKS ASSOCIATED WITH ACQUISITIONS AND EXPANSION STRATEGY
 
  General
 
     The Company's business strategy includes growth through the acquisition of
radiology practice assets, management service organizations ("MSOs"), ICs and
related businesses and entry into and maintenance of agreements to provide
management and administrative services to radiology practices, including
services designed to improve operating efficiencies. There can be no assurance
that the Company will be able to acquire and retain the assets of, or provide
management and administrative services to, additional radiology practices, MSOs
or ICs, profitably provide such services or successfully integrate such
additional relationships, or successfully improve operating efficiencies of the
Affiliated Practices. In addition, there can be no assurance that the assets of
radiology practices acquired in the future, or the relationships entered into in
the future, will be beneficial to the successful implementation of the Company's
overall strategy or that such assets and relationships will ultimately produce
returns that justify their related investment or implementation by the Company.
See "Business -- Business Strategy." Affiliated Practices acquired in the future
may have disparate cultures, operating and information systems and
organizational structures. Failure of the Company to acquire additional
practices and to successfully integrate and profitably manage or improve the
operating efficiencies of the Affiliated Practices could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     The Company's ability to expand its operations is dependent upon factors
such as its ability to (i) identify attractive and willing candidates for
acquisition, (ii) adapt or amend the Company's structure to comply with present
or future federal and state legal requirements affecting the Company's
arrangements with physician practice groups, including state prohibitions on
fee-splitting, corporate practice of medicine and referrals to facilities in
which physicians have a financial interest (see "-- Government Regulation"),
(iii) obtain regulatory approvals and certificates of need, where necessary, and
comply with licensing requirements applicable to the Company, the Affiliated
Practices and the physicians associated with the Affiliated Practices, including
their respective facilities (see "-- Government Regulation"), and (iv) expand
the Company's infrastructure and management to accommodate expansion. There can
be no assurance that the Company will be able to achieve these objectives or its
planned growth, that the assets of radiology practices, MSOs or ICs will
continue to be available for acquisition by the Company or that the addition of
such assets or management relationships will be profitable. Further,
acquisitions involve a number of special risks, including possible adverse
effects on the Company's operating results, diversion of management's attention
and resources, failure to retain key acquired personnel, amortization or
write-off of acquired intangible assets and risks associated with unanticipated
events or liabilities, some or all of which could have a material adverse effect
on the Company's business, financial condition and results of operations.
 
                                        9
<PAGE>   11
 
  Potential Need for Additional Capital
 
   
     The Company intends to finance future acquisitions by using shares of the
Common Stock for all or a portion of the consideration to be paid. In the event
that the Common Stock does not maintain a sufficient valuation, or potential
acquisition candidates are otherwise unwilling to accept Common Stock as part of
the consideration for the sale of the assets of their businesses, the Company
may be required to utilize more of its cash resources in order to pursue its
acquisition program. The Company may also incur indebtedness to fund future
acquisitions. The Company has executed the Credit Facility; however, the
availability of the Credit Facility is subject to a number of closing
conditions, including the consummation of this offering and the Reorganizations
as well as other customary closing and borrowing conditions. The Company's
growth could be limited and its existing operations impaired unless it is able
to obtain additional capital through subsequent debt or equity financings. There
can be no assurance that borrowing capacity under the Credit Facility will be
available to the Company when needed or that the Company will be able to obtain
additional financing or that, if available, such financing will be on terms
acceptable to the Company. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources." As a result, there can be no assurance that the Company will be able
to implement its acquisition strategy successfully.
    
 
  Risks Relating to Antitrust Laws
 
     The Company intends to expand both in areas where the Founding Affiliated
Practices currently operate as well as in new markets. Although the Company will
continue to structure its operations in an effort to comply with applicable
antitrust laws, there can be no assurance that federal or state governmental
authorities would not view the Company as being dominant in a particular market
and, therefore, cause the Company to divest itself of any particular Affiliated
Practice or related assets. In addition, these laws could prevent acquisitions
of practices that would be integrated into existing Affiliated Practices if such
acquisitions substantially lessen competition or tend to create a monopoly.
 
GOVERNMENT REGULATION
 
  State and Federal Fraud and Abuse, Anti-Kickback and Anti-Referral Laws
 
   
     Various federal and state laws regulate the relationships between providers
of health care services, physicians and other clinicians. See
"Business -- Government Regulation and Supervision." These laws include the
fraud and abuse provisions of the Social Security Act, which include the federal
"anti-kickback" and Stark or anti-referral laws. The "anti-kickback" laws
prohibit the offering, payment, solicitation or receipt of any direct or
indirect remuneration for the referral of Medicare, Medicaid or other
governmental program patients or for the recommendation, leasing, arranging,
purchasing, ordering or providing of Medicare or Medicaid covered services,
items or equipment. Violations of the "anti-kickback" laws may result in
substantial civil or criminal penalties for individuals or entities, including
large civil monetary penalties and exclusion from participation in Medicare,
Medicaid and other governmental programs. The Balanced Budget Act of 1997
("BBA97") contains certain reform provisions relating to Medicare, Medicaid and
other governmental programs, that are intended to assist the government in its
efforts to enforce the "anti-kickback" laws, including adding a civil money
penalty and broadening the scope of circumstances under which mandatory or
permissive exclusion from the programs may apply. Such exclusion and penalties,
if applied to the Company's owned, operated or managed ICs, the Affiliated
Practices or physicians affiliated with the Affiliated Practices, could result
in significant loss of reimbursement to the affected individuals and entities. A
determination of liability under any such laws could have a material adverse
effect on the Company's business, financial condition and results of operations.
    
 
   
     Certain provisions contained in the Omnibus Budget Reconciliation Act of
1989 ("Stark I") and the Omnibus Budget Reconciliation Act of 1993 ("Stark II"),
and subsequent amendments, prohibit physician referrals for certain "designated
health services," including, without limitation, radiology services to entities
with which a physician or an immediate family member has a financial
relationship (collectively, the "Stark Law"). The Stark Law also prohibits
entities from presenting or causing to be presented a claim or bill to any
individual, third-party payor, or other entity for designated health services
furnished under a prohibited
    
 
                                       10
<PAGE>   12
 
   
referral. A violation of the Stark Law by the Company, an Affiliated Practice or
physicians affiliated with the Affiliated Practices, may result in significant
civil penalties, which may include exclusion or suspension of the physician or
entity from future participation in the Medicare and Medicaid programs and
substantial fines. A determination of violation under such law by any of these
persons or entities could have a material adverse effect on the Company's
business, financial condition and results of operations.
    
 
   
     Several states have adopted laws similar to the federal "anti-kickback" and
Stark Law that cover patients in private programs as well as government
programs. All of the states in which the Founding Affiliated Practices are
located have adopted a form of "anti-kickback" law and almost all of those
states (California, Kansas, Maryland and New York) have also adopted a form of
anti-referral law. These laws and the interpretations thereof vary from state to
state and are enforced by the courts and regulatory authorities, each with broad
discretion. A determination of liability under any such laws could have a
material adverse effect on the Company's business, financial condition and
results of operations.
    
 
  Corporate Practice of Medicine; Fee Splitting
 
   
     The laws of many states, including each of the states in which the Founding
Affiliated Practices are located, also prohibit business corporations, such as
the Company, from exercising control over the medical judgments or decisions of
physicians and from engaging in certain financial arrangements, such as fee-
splitting, with physicians. These laws and their interpretations vary from state
to state and are enforced by both the courts and regulatory authorities, each
with broad discretion. The Company's strategy is to acquire certain assets and
assume certain liabilities of, and to enter into Service Agreements with,
Affiliated Practices. Pursuant to the Service Agreements, the Company will
provide management, administrative, technical and other non-medical services to
the Affiliated Practices in exchange for a service fee. The Company intends to
structure its relationships with the Affiliated Practices (including the
purchase of assets and the provision of services under the Service Agreements)
to keep the Company from engaging in the practice of medicine or exercising
control over the medical judgments or decisions of the Affiliated Practices or
their physicians. There can be no assurance that regulatory authorities or other
parties will not assert that the Company is engaged in the corporate practice of
medicine in such states or that the payment of service fees to the Company by
the Affiliated Practices pursuant to the Service Agreements constitutes
fee-splitting or the corporate practice of medicine. If such a claim was
successfully asserted, the Company could be subject to civil and criminal
penalties and could be required to restructure or terminate its contractual
arrangements. Such results or the inability of the Company to successfully
restructure its relationships to comply with such statutes could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business -- Service Agreements."
    
 
  Licensing and Certification Laws
 
     The ownership, construction, operation, expansion and acquisition of ICs
are subject to various federal and state laws, regulations and approvals
concerning the licensing of facilities, personnel, certificates of need and
other required certificates for certain types of health care facilities and
major medical equipment. Although the laws of the five states in which the
Founding Affiliated Practices are located do not subject ICs to certificate of
need or separate licensing requirements as stand-alone imaging centers, the laws
of other states could limit the Company's ability to acquire new imaging
equipment or expand or replace its equipment at ICs in other states. No
assurances can be given that the required regulatory approvals for any future
acquisitions, expansions or replacements will be granted to the Company, and the
failure to obtain such approvals could materially and adversely affect the
Company's business, financial condition and results of operations. See
"Business -- Government Regulation and Supervision."
 
  Compliance
 
   
     Although the Company intends to structure and conduct its proposed
operation so as to comply with applicable federal and state laws, neither the
Company's current or anticipated business operations nor the operations of the
Founding Affiliated Practices have been the subject of judicial or regulatory
interpretation. There can be no assurance that a review of the Company's
business by courts or regulatory authorities will not
    
 
                                       11
<PAGE>   13
 
   
result in determinations that could adversely affect the operations of the
Company or that the health care regulatory environment will not change so as to
restrict the Company's operations. In addition, the regulatory framework of
certain jurisdictions may limit the Company's expansion into or ability to
continue operations within such jurisdictions, unless the Company is able to
modify its operational structure to conform with such regulatory framework. Any
limitation on the Company's ability to expand could have a material adverse
effect on the Company's business, financial condition and results of operations.
    
 
  Reform Initiatives; Increased Enforcement
 
   
     In addition to existing government health care regulations, there have been
numerous initiatives at the federal and state levels for comprehensive reforms
affecting the payment for and availability of health care services. The Company
believes that such initiatives will continue for the foreseeable future. Certain
aspects of these reforms as proposed in the past, such as further reductions in
Medicare and Medicaid payments, if adopted, could materially and adversely
affect the Company's business, financial condition and results of operations.
    
 
   
     Federal regulatory and law enforcement authorities have recently increased
enforcement activities with respect to Medicare and Medicaid fraud and abuse
regulations and other reimbursement laws and rules, including laws and
regulations that govern the Company's activities. There can be no assurance that
the Company's activities will not be investigated, that claims will not be made
against the Company or that increased enforcement activities will not directly
or indirectly have an adverse effect on the Company's business, financial
condition and results of operations or the market price of the Common Stock.
    
 
  Insurance Laws and Regulations
 
     Certain states have enacted statutes or adopted regulations affecting risk
assumption in the health care industry, including statutes and regulations that
subject any physician or physician network engaged in risk-based contracting to
applicable insurance laws and regulations, which may include, among other
things, laws and regulations providing for minimum capital requirements and
other safety and soundness requirements. Failure to comply with these statutes
and regulations could have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, implementation of
additional regulations or compliance requirements could result in substantial
costs to the Company and the Affiliated Practices. The inability to enter into
capitated or other risk-sharing arrangements or the cost of complying with
certain applicable laws that would permit expansion of the Company's risk-based
contracting activities could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
REIMBURSEMENT TRENDS AND COST CONTAINMENT
 
   
     The Company's revenue will be derived from service fees paid to the Company
by the Affiliated Practices pursuant to the Service Agreements and through its
ownership, operation and management of ICs. Substantially all of the revenue of
the Affiliated Practices and such ICs is currently derived from government
sponsored health care programs (principally, Medicare and Medicaid) and private
third-party payors. During the six month period ended June 30, 1997,
approximately 21% of the combined medical service revenues, net of the Founding
Affiliated Practices was derived from government approved health care programs
and approximately 79% of the combined medical service revenues, net of the
Founding Affiliated Practices was derived from private third-party payors. The
health care industry is experiencing a trend toward cost containment as
government and private third-party payors seek to impose lower reimbursement and
utilization rates and negotiate reduced payment schedules with service
providers. The Company believes that these trends will continue to result in a
reduction from historical levels in per-patient revenue for its Affiliated
Practices and ICs and that the results of operations of the Affiliated Practices
are likely to continue to be affected by lower reimbursement levels. Further
reductions in payments or other changes in reimbursement for health care
services could have a material adverse effect on the Company's business,
financial condition and results of operations unless the Company is otherwise
able to offset such payment reductions.
    
 
                                       12
<PAGE>   14
 
     Rates paid by private third-party payors are based on established physician
and hospital charges and are generally higher than Medicare reimbursement rates.
Any decrease in the relative number of patients covered by private insurance
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
   
     The federal government has implemented, through the Medicare program, a
resource-based relative value scale ("RBRVS") payment methodology for physician
services. The RBRVS is a fee schedule that, except for certain geographical and
other adjustments, pays similarly-situated physicians the same amount for the
same services. The RBRVS is adjusted each year and is subject to increases or
decreases at the discretion of Congress. To date, the implementation of the
RBRVS has reduced payment rates for certain of the procedures historically
provided by the Affiliated Practices. BBA 97 provides for reductions in the rate
of growth of payments for physician services, including services historically
provided by the Affiliated Practices, in the amount of $5.3 billion over a
five-year period ending in 2002. In addition, BBA 97 provides for the
implementation of a resource-based methodology for payment of physician practice
expenses under the physician fee schedule over a four-year period beginning in
fiscal year 1999. Adoption of this methodology is expected to reduce payments
for services historically provided by the Affiliated Practices.
    
 
     RBRVS-type payment systems also have been adopted by certain private
third-party payors and the Company believes that it is likely that other private
third-party payors will adopt this payment methodology in the future.
Wider-spread implementation of such programs could reduce payments by private
third-party payors and could indirectly reduce the Company's operating margins
to the extent that the costs of providing management, administrative, technical
and non-medical services related to such procedures could not be proportionately
reduced. There can be no assurance that such cost reduction efforts by
governmental or private third-party payors will not have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business -- Government Regulation and Supervision."
 
   
     Private third-party payors and Medicare and Medicaid have increased their
use of managed care as a means of cost containment. Increasingly, private
third-party payors negotiate discounts from established physician and hospital
charges or require capitation or other risk sharing arrangements as a condition
of patient referral to physician groups such as the Affiliated Practices. BBA 97
also includes provisions designed to increase the enrollment of Medicare and
Medicaid participants in managed care programs. The inability of the Company to
negotiate satisfactory arrangements with managed care companies could have a
material adverse effect on the Company's business, financial condition and
results of operations.
    
 
RISKS ASSOCIATED WITH MANAGED CARE CONTRACTS AND CAPITATED FEE ARRANGEMENTS
 
   
     During the six month period ended June 30, 1997, approximately 94% of the
combined medical service revenues, net of the Founding Affiliated Practices was
derived from payments made on a fee-for-service basis by patients and
third-party payors (including government programs) and approximately 6% of the
combined medical service revenues, net of the Founding Affiliated Practices was
derived from capitated arrangements. Under capitated or other risk-sharing
arrangements, the health care provider typically is paid a pre-determined amount
per-patient per-month from the payor in exchange for providing all necessary
covered services to patients covered under the arrangement. Such contracts pass
much of the financial risk of providing care, including the risk of
over-utilization, from the payor to the provider. The Company believes that its
success will, in part, depend on the Company's ability to negotiate, on behalf
of the Affiliated Practices and the Company's owned, operated or managed ICs,
contracts with HMOs, employer groups and other third-party payors pursuant to
which services will be provided on a risk-sharing or capitated basis by some or
all of such Affiliated Practices or ICs. Risk-sharing arrangements result in
greater predictability of revenue but greater unpredictability of expenses and,
consequently, profitability. There can be no assurance that the Company will be
able to negotiate, on behalf of its Affiliated Practices or the Company's owned,
operated or managed ICs, satisfactory arrangements on a capitated or other
risk-sharing basis. In addition, to the extent that patients or enrollees
covered by such contracts require more frequent or extensive care than is
anticipated, the Company would incur unanticipated costs not offset by
additional revenue, which would reduce operating margins. In the worst case, the
revenue derived from such contracts may be insufficient to cover the costs of
the services
    
 
                                       13
<PAGE>   15
 
provided. Any such reduction or elimination of earnings could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
   
     Furthermore, various quality assurance programs and organizations have been
created to scrutinize managed care organizations and their providers. In
response to such programs, managed care organizations and providers have
developed their own quality assurance programs to address a variety of areas,
including patient access to services, patient satisfaction, outcomes and
performance measures and utilization of services. These quality assurance
measures involve various costs associated with their implementation and
operation and depend, in part, upon the sophistication and compatibility of
existing systems and operations of the Affiliated Practices as well as the
Company's ability to integrate those systems and operations. The Company's
inability to develop strong quality assurance measures in conjunction with its
Affiliated Practices could place the Company and its Affiliated Practices at a
competitive disadvantage and have a material adverse effect on the Company's
business, financial condition and results of operations.
    
 
COMPETITION
 
   
     The Company is under competitive pressure to acquire and retain the assets
of, and to provide management and administrative services to, additional
radiology practices, MSOs and ICs. There are a number of publicly-traded
companies focused on owning or managing ICs, including U.S. Diagnostic, Inc.,
Medical Resources, Inc., TeamHealth (a subsidiary of MedPartners, Inc.) and
Health Images (a division of HEALTHSOUTH Corporation). The Company is aware of
at least two privately-held physician practice management companies focused on
professional and technical radiology services. Several companies, both publicly
and privately held, that have established operating histories and, in some
instances, greater resources than the Company are pursuing the acquisition of
general and specialty physician practices (including radiology in the case of
TeamHealth) and the management of such practices. Additionally, some hospitals,
clinics, health care companies, HMOs and insurance companies engage in
activities similar to those of the Company. There can be no assurance that the
Company will be able to compete effectively for the acquisition of, or
affiliation with, radiology practices, that additional competitors will not
enter the market, that such competition will not make it more difficult or
expensive to acquire the assets of, and provide management and administrative
services to, radiology practices on terms beneficial to the Company, or that
competitive pressures will not otherwise adversely affect the Company. See
"Business -- Competition."
    
 
   
     The Affiliated Practices and the Company's owned, operated or managed ICs
compete with numerous local radiology and imaging service providers. The Company
believes that changes in governmental and private reimbursement policies and
other factors have resulted in increased competition among providers for the
provision of medical services to consumers. There can be no assurance that the
Affiliated Practices and the Company's owned, operated or managed ICs will be
able to compete effectively in the markets they serve, which inability to
compete could materially and adversely affect the Company's business, financial
condition and results of operations.
    
 
   
     Further, the Affiliated Practices will compete with other providers for
managed care contracts. The Company believes that trends toward managed care
have resulted, and will continue to result, in increased competition for such
contracts. Other radiology practices and MSOs may have more experience than the
Affiliated Practices and the Company in obtaining such contracts. There can be
no assurance that the Affiliated Practices and the Company will be able to
obtain future business from managed care entities which will allow the Company
to compete effectively in the markets they serve, which inability to compete
could materially and adversely affect the Company's business, financial
condition and results of operations.
    
 
POTENTIAL LIABILITY AND INSURANCE; LEGAL PROCEEDINGS
 
     The provision of medical services entails an inherent risk of professional
malpractice and other similar claims. Although the Company intends to structure
its relationships with the Affiliated Practices under the Service Agreements in
a manner that will not constitute the practice of medicine, there can be no
assurance that claims, suits or complaints relating to services and products
provided by Affiliated Practices will not be asserted against the Company in the
future. Additionally, the Company owns, operates and manages ICs,
 
                                       14
<PAGE>   16
 
which exposes the Company to professional liability claims. The Company
maintains insurance policies with coverages that it believes are appropriate in
light of the risks attendant to its business. In addition, pursuant to the
Service Agreements, the Affiliated Practices are required to maintain
professional liability insurance. Nevertheless, there can be no assurance that
successful malpractice or other claims will not be asserted against the
Affiliated Practices or the Company that exceed the scope of coverage or
applicable policy limits or which could otherwise have a material adverse effect
on the Company's business, financial condition and results of operations.
 
   
     The availability and cost of professional liability insurance has been
affected by various factors, many of which are beyond the control of the Company
and the Affiliated Practices. There can be no assurance that adequate liability
insurance will be available to the Company and the Affiliated Practices in the
future at acceptable costs or that the future cost of such insurance to the
Company and the Affiliated Practices will not have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Business -- Corporate Liability and Insurance."
    
 
   
     In connection with the Reorganizations, the Company will assume and succeed
to substantially all of the obligations of each Founding Affiliated Practice.
Further, in connection with the acquisition of the assets of other Affiliated
Practices in the future, the Company anticipates that it will typically succeed
to some or all of the liabilities of such Affiliated Practices. Therefore,
claims may be asserted against the Company for events that occurred prior to the
acquisition of the assets of the Affiliated Practices.
    
 
   
     The physicians employed by the Founding Affiliated Practices are from time
to time subject to malpractice claims. Such malpractice claims, if successful,
could result in damages which may exceed applicable insurance coverage for such
malpractice claims. While each Founding Affiliated Practice and the Company
maintains insurance consistent with industry practice, there can be no assurance
that the amount of insurance currently maintained by them will satisfy all
claims made against them or that a Founding Affiliated Practice or the Company
will be able to obtain insurance in the future at satisfactory rates or in
adequate amounts. Further, there are certain claims against the Founding
Affiliated Practices which are not covered by insurance (see note 11 to the
Consolidated Financial Statements of Advanced Radiology, LLC and Subsidiary).
The Company cannot predict the effect that any such claims, regardless of their
outcome, might have on its business or reputation.
    
 
   
     The Company has not been named in any of the lawsuits against a Founding
Affiliated Practice; however, there can be no assurance that the Company will
not subsequently be named as a defendant in one or more of these lawsuits
following consummation of the Reorganizations. Each Founding 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 a Founding Affiliated Practice is
not required or is unable to satisfy its indemnification obligations to the
Company, the Company's business, results of operations and financial condition
could be materially adversely affected.
    
 
   
     On September 1, 1997, a new law became effective in the state of Texas that
permits injured patients to sue health insurance carriers, HMOs and other
managed care entities for medical malpractice. There can be no assurance that
this law will not increase the cost of liability insurance to the Company for
services provided in Texas or any other states in which the Company does
business if similar legislation is adopted in those states.
    
 
   
     In connection with the Reorganizations, the shareholders of the Founding
Affiliated Practices have agreed to indemnify the Company for certain claims.
There can be no assurance that the Company will be able to receive payment under
any such indemnity agreements or that the failure to fully recover such amounts
will not have a material adverse effect on the Company's business, financial
condition and results of operations.
    
 
                                       15

DEPENDENCE ON INFORMATION SYSTEMS
 
   
     The current information systems of the Founding Affiliated Practices
consist of disparate, non-integrated accounting, practice management and other
information systems. In order to facilitate the extensive information management
requirements necessary to effectively manage operations, compete for managed
care contracts and achieve standardization and economies of scale, the Company
intends to create a network infrastructure and deploy two company-wide
information systems. The design, selection and implementation of the various
components of these systems and the integration throughout the Company and the
Affiliated Practices will entail an aggregate estimated expenditure of
approximately $3.0 million and significant management resources. The Company
intends to implement such systems within the first 12 months following this
offering, but may experience unanticipated delays, complications and expenses in
implementing, integrating and operating such systems. Furthermore, such systems
may require modifications, improvements or replacements as the Company expands
or if new technologies become available. Such modifications, improvements or
replacements may require substantial expenditures and may require interruptions
in operations during periods of implementation. There can be no assurance that
the Company will be able to implement and operate these information systems
effectively or that these systems will produce the expected benefits. The
failure to successfully implement and maintain operational and financial
information systems could prevent the Company from efficiently accumulating data
from disparate systems maintained by the Affiliated Practices and generating
operational data necessary to more effectively manage the Affiliated Practices
which could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Operations and
Development -- Information Management."
    
 
DEPENDENCE ON KEY PERSONNEL
 
   
     The Company is dependent upon the ability and experience of its executive
officers and key personnel for the management of the Company and the
implementation of its business strategy. The Company currently has employment
contracts with four of its executive officers and a consulting agreement (which
will become effective immediately following this offering) with one other
executive officer. Because of the difficulty in finding adequate replacements
for such personnel, the loss of the services of any such personnel or the
Company's inability in the future to attract and retain management and other key
personnel could have a material adverse effect on the Company's business,
financial condition and results of operations. The Company does not maintain key
man insurance for any of its executive officers. See "Management -- Employment
Agreements; Covenants-Not-to-Compete" and "Certain Transactions."
    
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
     The market price of the Common Stock could be adversely affected by the
sale of substantial amounts of Common Stock in the public market following this
offering. Upon the completion of the Reorganizations, the conversion of the
Convertible Notes and completion of this offering, the Company will have
outstanding 18,321,982 shares of Common Stock, assuming an initial public
offering price of $15.00 per share. The 5,000,000 shares of Common Stock to be
sold in this offering will be freely tradable without restriction under the
Securities Act of 1993, as amended (the "Securities Act"), unless acquired by
"affiliates" of the Company, as that term is defined under the Securities Act or
contractually restricted.
    
 
   
     Simultaneously with the closing of this offering, security holders of the
Founding Affiliated Practices will receive, in the aggregate, 10,884,482 shares
of Common Stock as a portion of the consideration for their practices, which
shares will have been registered under the Securities Act. Certain other
stockholders of the Company will hold, in the aggregate, an additional 2,000,000
shares of Common Stock, none of which are being offered by this Prospectus and
none of which were acquired in transactions registered under the Securities Act.
Such unregistered shares may not be sold except in transactions registered under
the Securities Act or pursuant to an exemption from registration. The holders of
these 12,884,482 shares of Common Stock have entered into agreements with the
Company pursuant to which such holders have agreed not to sell any shares of
Common Stock owned by them at the time of consummation of the Reorganizations
for a period of 12 months following this offering, and to thereafter limit the
sale of such Common Stock to 25% of such
    
 
                                       16
<PAGE>   18
 
shares upon expiration of such 12-month period following this offering; up to an
additional 25% of such shares upon expiration of the 18-month period following
this offering, and the remaining 50% of such shares upon expiration of a
24-month period following this offering. Further, each of the holders of the
Convertible Notes have entered into agreements with the Company pursuant to
which each holder has agreed not to sell any portion of the Convertible Notes or
any shares of the Common Stock issued or issuable upon conversion thereof for a
period of the 24 months following the date the Convertible Notes were issued to
such holder (which Notes were issued between September 30, 1996 and December 31,
1996). The Company has agreed with the Underwriters not to waive the restrictive
provisions of those agreements for 180 days after the date of this Prospectus
without the prior written consent of Smith Barney Inc. Upon expiration of these
agreements, the registered shares of Common Stock will be eligible for resale in
the public market and the unregistered shares of Common Stock, the Convertible
Notes and the shares of Common Stock issued or issuable upon conversion of the
Convertible Notes will become eligible for sale in the public market, subject to
the provisions of Rule 144 of the Securities Act. See "Shares Eligible for
Future Sale."
 
   
     In addition, the Company and its officers and directors and substantially
all other holders of Common Stock and securities convertible into or exercisable
or exchangeable for Common Stock have agreed that for a period of 180 days after
the date of this Prospectus they will not, without the prior written consent of
Smith Barney Inc., offer, sell, contract to sell or otherwise dispose of Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock except, in the case of the Company, in certain limited
circumstances. See "Shares Eligible for Future Sale."
    
 
CONTROL BY EXISTING STOCKHOLDERS
 
   
     Following the completion of the Reorganizations, the conversion of the
Convertible Notes and completion of this offering, members of the Board of
Directors and the executive officers of the Company will own approximately 12.3%
of the outstanding shares of Common Stock and the security holders of the
Founding Affiliated Practices will own approximately 59.4% of the outstanding
shares of Common Stock (including shares received by Directors of the Company
who are also security holders of Founding Affiliated Practices). The Company's
Amended and Restated Bylaws do not provide for cumulative voting. The Company's
Amended and Restated Bylaws provide that, following the consummation of this
offering, the Board of Directors must nominate two physicians licensed to
practice medicine from the Affiliated Practices for election to the Board of
Directors at each annual meeting of the Company's stockholders (three physicians
licensed to practice medicine from the Affiliated Practices if the size of the
Board of Directors increases to nine). Although to the knowledge of the Company
such directors and other persons do not have any arrangements or understandings
among themselves with respect to the voting of the shares of Common Stock
beneficially owned by such persons, following the completion of this offering,
such persons will be able to control the affairs of the Company. See "Principal
Stockholders."
    
 
ANTI-TAKEOVER CONSIDERATIONS
 
     Certain provisions of the Company's Restated Certificate of Incorporation,
the Company's Amended and Restated Bylaws and Delaware law could discourage
potential acquisition proposals, delay or prevent a change in control of the
Company and, consequently, limit the price that investors might be willing to
pay in the future for shares of the Common Stock. These provisions include the
inability to remove directors except for cause and the Company's ability to
issue, without further stockholder approval, shares of preferred stock with
rights and privileges senior to the Common Stock. The Company also is subject to
Section 203 of the Delaware General Corporation Law which, subject to certain
exceptions, prohibits a Delaware corporation from engaging in any of a broad
range of business combinations with an "interested stockholder" for a period of
three years following the date that such stockholder became an interested
stockholder. See "Description of Capital Stock."
 
   
     The Company has entered into employment agreements with four of its
executive officers which contain provisions that require the Company to pay
certain amounts to such employees upon their termination following certain
events, including a change of control of the Company. Such agreements may delay
or prevent
    
 
                                       17
<PAGE>   19
 
a change of control of the Company. See "Management -- Employment Agreements;
Covenants-Not-to-Compete."
 
NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to this offering, there has been no public market for the Common
Stock, and there can be no assurance that an active public market for the Common
Stock will develop or continue after this offering. The initial public offering
price has been determined by negotiations among the Company and the several
Underwriters named herein, and may not be indicative of the market price for the
Common Stock after this offering. See "Underwriting" for factors considered in
determining the initial public offering price. There can be no assurance that
the market price for the Common Stock will not decline below the initial market
price. From time to time after this offering, there may be significant
volatility in the market price for the Common Stock. The trading price of the
Common Stock could be subject to significant fluctuations in response to
variations in the Company's quarterly operating results, general trends in the
Company's industry, regulatory and reimbursement developments, changes in
earnings estimates by securities analysts and other factors affecting the
Company's industry or the securities market as a whole. Any such fluctuations
may adversely affect the market price of the Common Stock.
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
   
     The purchasers of the shares of Common Stock offered hereby will experience
immediate and substantial dilution in the net tangible book value of their
shares of Common Stock in the amount of $13.17 per share (based on an assumed
public offering price of $15.00 per share and after giving effect to the
Reorganizations and conversion of the Convertible Notes). See "Dilution." In the
event the Company issues additional Common Stock in the future, including shares
that may be issued in connection with future acquisitions, or upon the exercise
of options, purchasers of Common Stock in this offering may experience further
dilution in the net tangible book value per share of Common Stock.

<PAGE>   20
 
                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby, based upon an assumed initial public offering price of $15.00
per share and after deducting the estimated offering expenses payable by the
Company and the underwriting discounts and commissions ("Net Proceeds"), are
estimated to be approximately $66.7 million ($77.1 million if the Underwriters'
over-allotment option is exercised in full). Of this amount, approximately $54.4
million will be used to pay the cash portion of the consideration for the assets
of the Founding Affiliated Practices and approximately $12.2 million will be
used to repay certain indebtedness previously incurred by the Founding
Affiliated Practices. The indebtedness to be repaid from the Net Proceeds bears
interest at annual rates ranging from 5.35% to 10.36% with a weighted average
interest rate of 8.20% and would otherwise mature at various dates through the
year 2001. The indebtedness incurred by the Founding Affiliated Practices within
the last year that is to be repaid with portions of the Net Proceeds was
incurred for capital expenditures, acquisitions and working capital.
    
 
                                DIVIDEND POLICY
 
   
     APPI has not paid any cash dividends since its inception. The Company
currently intends to retain all future earnings for the operation and expansion
of its business and, accordingly, the Company does not anticipate that any cash
dividends will be declared or paid on its Common Stock in the foreseeable
future. In addition, the Credit Facility prohibits the payment of dividends on
the Common Stock. Any payment of such dividends in the future will be at the
discretion of the Board of Directors and will depend upon the earnings and
financial position of the Company, its results of operations, its capital needs,
plans for expansion, contractual restrictions to which the Company may be
subject (including pursuant to the Credit Facility) and such other factors as
the Board of Directors may deem appropriate. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."

     The following table sets forth the capitalization of the Company (i) as of
June 30, 1997, (ii) on a pro forma basis giving effect to the Reorganizations
and the distribution to the Founding Affiliated Practices and (iii) on a pro
forma basis as adjusted to give effect to (a) the sale of the 5,000,000 shares

$15.00 per share and after deducting underwriting discounts and commissions and
estimated offering expenses) and the application of the estimated Net Proceeds
therefrom as described under "Use of Proceeds," (b) the conversion of the
Convertible Notes and (c) borrowings of approximately $13.6 million under the
Credit Facility to occur upon the consummation of this offering to refinance
substantially all funded debt previously incurred by the Founding Affiliated

Pro Forma Combined Balance Sheet," "Selected Financial Data," and the financial
statements of APPI and the Founding Affiliated Practices included elsewhere
herein.
    
 
   
     The Reorganizations include (a) the issuance of 10,884,482 shares of Common
Stock to the Founding Affiliated Practices, (b) the payment of $54.4 million,
all of which is to be paid to the Founding Affiliated Practices in cash at
closing and (c) the receipt of assets used by the Founding Affiliated Practices,
and the assumption of related debt, with a net book value of $22.2 million at
June 30, 1997.

                                    DILUTION
 
   
     The net tangible book value of the Company at June 30, 1997 was
approximately $(3.1 million) or $(1.55) per share. Giving effect to the
Reorganizations and the conversion of the Convertible Notes (but not this
offering), the pro forma net tangible book value of the Company at June 30, 1997
would have been approximately $21.8 million or $1.63 per share. Therefore, the
increase in pro forma net tangible book value per share due to the
Reorganizations is $3.18 per share. After giving effect to the sale of the
shares of Common Stock offered hereby (assuming a public offering price of
$15.00 per share and after deducting underwriting discounts and commissions and
estimated offering expenses), the adjusted pro forma net tangible book value of
the Company at June 30, 1997 would have been approximately $33.6 million or
$1.83 per share, representing an immediate increase in net tangible book value
of $.20 per share to existing stockholders and an immediate dilution of $13.17
per share to the investors purchasing shares in this offering ("New Investors").
The following table illustrates this per share dilution to New Investors:

(1) Consists of management, the holders of the Convertible Notes, John
    Pappajohn, Derace L. Schaffer, M.D., and persons receiving Common Stock in
    connection with the Reorganizations. Total consideration for existing
    stockholders represents the combined stockholders' equity before this
    offering adjusted to reflect the payment of approximately $54.4 million in
    cash by the Company in connection with the Reorganizations and the
    conversion of the Convertible Notes. The tangible assets received in
    exchange for this consideration includes the net book value of the Founding
    Affiliated Practices of approximately $22.2 million. See "Capitalization."
    
 
    As of September 12, 1997, there were 1,421,000 shares issuable upon the
    exercise of stock options having a weighted average exercise price of $1.68
    per share. To the extent these options are exercised, there will be further
    dilution to New Investors.

                   UNAUDITED PRO FORMA COMBINED BALANCE SHEET
 
   
     The following unaudited pro forma combined balance sheet gives effect to
the Reorganizations as a combination of promoter interests, at historical costs,
and is based upon the historical financial statements of APPI and each of the
Founding Affiliated Practices. In addition, the unaudited pro forma combined
balance sheet gives effect to this offering (assuming an initial public offering
price of $15.00 per share), the conversion of the Convertible Notes and
borrowings of approximately $13.6 million under the Credit Facility to refinance
certain indebtedness previously incurred by the Founding Affiliated Practices.
The unaudited pro forma combined balance sheet gives effect to the completion of
such transactions as if they had occurred on June 30, 1997. Due to the fact that
the Company has had no significant operations to date, no pro forma statement of
operations has been included in this Prospectus. The amount and composition of
costs to be incurred by the Company related to the provision of management
services to the Founding Affiliated Practices may differ from the costs
historically incurred by the Founding Affiliated Practices; therefore, the costs
presented in the individual financial statements of the Founding Affiliated
Practices may not be representative of the Company's costs on a pro forma basis.
The unaudited pro forma combined balance sheet and notes thereto should be read
in connection with the other financial information, including the audited
financial statements of APPI and each of the Founding Affiliated Practices and
notes thereto, included elsewhere in this Prospectus.
    
 
     The unaudited pro forma combined balance sheet is presented for
illustrative purposes only and is not necessarily indicative of the financial
position that would have been achieved if the Reorganizations, the conversion of
the Convertible Notes and this offering had been consummated on June 30, 1997.

                   NOTES TO PRO FORMA COMBINED BALANCE SHEET
    
 
     APPI was incorporated in April 1996 and has conducted no significant
operations and generated no revenue to date other than in connection with this
offering and the Reorganizations. The following is a summary of the adjustments
reflected in the Unaudited Pro Forma Combined Balance Sheet assuming the
Reorganizations, this offering and conversion of the Convertible Notes. The
Reorganizations will be accounted for as a combination of promoter interests, at
historical costs, under generally accepted accounting principles. APPI will not
be acquiring equity interests in the Founding Affiliated Practices, but will be
acquiring substantially all of the assets of the Founding Affiliated Practices.
 
     Upon completion of the Reorganizations, the Company will not consolidate
the financial position of the Founding Affiliated Practices.
 
     The adjustments reflected in the unaudited pro forma combined balance sheet
are as follows:
 
   
        (a)  To eliminate assets not acquired and liabilities not assumed by the
             Company and to reflect the $54.4 million distribution to the
             Founding Affiliated Practices. The Company will not be assuming any
             physician related assets and liabilities, such as notes receivable
             from physicians, accrued physician compensation, deferred physician
             compensation, and assets and liabilities related to other physician
             benefit plans.
    
 
        (b)  To record the establishment of deferred income taxes for the
             Company after the Reorganizations.
 
        (c)  To record the issuance of Common Stock to the Founding Affiliated
             Practices.
 
        (d)  To record the reclassification of the Founding Affiliated
             Practices's earnings (deficit) accumulated prior to this offering
             to additional paid-in capital.
 
   
        (e)  To reflect the effects of this offering, including the use of
             estimated Net Proceeds from the issuance of Common Stock, to pay
             the $54.4 million distribution to the Founding Affiliated Practices
             and to reduce debt.
    
 
   
        (f)  To reflect borrowings under the $115,000,000 credit facility (the
             "Credit Facility") with GE Capital Corporation ("GE Capital") which
             will occur contemporaneously with this offering. The proceeds from
             these borrowings will be used to refinance all remaining funded
             debt, except capital leases and one note payable.
    
 
   
        (g)  To reflect estimated deferred financing costs related to the Credit
             Facility.
    
 
   
        (h)  To reflect the conversion of all $3,500,000 of Convertible Notes
             issued by the Company into 437,500 shares of Common Stock.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   
     The following discussion and analysis contains certain statements of a
forward-looking nature relating to future events or the future financial
performance of the Company. Such statements are only predictions and the actual
events or results may differ materially from the results discussed in the
forward-looking statements. Factors that could cause or contribute to such
differences include, but are not limited to, those discussed in "Risk Factors,"
as well as those discussed elsewhere in this Prospectus. The historical results
set forth in this discussion and analysis are not indicative of trends with
respect to any actual or projected future financial performance of the Company.
This discussion and analysis should be read in conjunction with the audited
financial statements of APPI and Notes thereto included elsewhere in this
Prospectus.
    
 
OVERVIEW
 
   
     APPI has conducted no significant operations to date but will be acquiring,
in connection with the Reorganizations and this offering, tangible and
intangible assets and liabilities of, and entering into Service Agreements with,
the Founding Affiliated Practices. Through the Service Agreements, the Company
will be providing management, administrative, technical and non-medical services
to the Affiliated Practices in return for service fees. The service fees
represent the physician groups revenue, net less amounts retained by physician
groups. Physician groups revenue, net consists of the revenue of the Affiliated
Practices reported at the estimated realizable amounts from patients,
third-party payors and others for services rendered, net of contractual and
other adjustments. The service fees payable to the Company by the Affiliated
Practices under the Service Agreements vary based on the fair market value, as
determined in arms' length negotiations, and the nature and extent of services
provided. Where state law allows, the service fees due under the Service
Agreements are derived from two distinct revenue streams: (i) the Affiliated
Practice pays a service fee based on a negotiated percentage (Founding
Affiliated Practice service fees range from 20% to 25%) of the adjusted
professional revenues as defined in the Service Agreement; and (ii) the
Affiliated Practice pays a service fee based on 100% of the adjusted technical
revenues as defined in the Service Agreement, which equals the fair value of the
services provided. 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. As structured, the base service fee will 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 will display the revenues, net of the amounts retained by
physicians, and expenses of the Affiliated Practices in its historical
consolidated statement of operations once the Reorganizations have occurred. The
aggregate initial base service fees in states where the law requires a flat fee
structure are $9,261,000. 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 non-physician costs) from physician groups revenue of the Affiliated
Practice. In addition, the Company receives income from joint ventures in which
the Affiliated Practices hold ownership interests. Physician compensation is
determined by the Affiliated Practices pursuant to employment arrangements
between the Affiliated Practice and the individual physicians. The Company does
not participate in the negotiation of physician employment arrangements.
    
 
   
     The Company expects that the expenses incurred by the Company associated
with its obligations under the Service Agreements generally will be the same as
the operating costs and expenses that would have otherwise been incurred by the
Founding Affiliated Practices, including: the salaries, wages and benefits of
non-physician personnel; medical supplies expenses involved in administering
technical aspects of the practices; the office (general and administrative)
expenses of the practices; depreciation and amortization of assets acquired from
the Affiliated Practices; and certain other items. As further described in
"Business -- Business Strategy," the Company intends to implement measures
designed to reduce these operating costs and expenses through purchase
discounts, economies of scale, benchmarking programs and more effective
equipment utilization. In addition to the operating costs and expenses discussed
above, the Company will be
    
 
                                       26
<PAGE>   28
 
incurring additional personnel and administrative expenses in connection with
establishing and maintaining corporate and regional offices, which will provide
management, administrative, marketing and acquisition services.
 
   
     In accordance with Staff Accounting Bulletin ("SAB") No. 48, "Transfers of
Nonmonetary Assets by Promoters or Shareholders," published by the Securities
and Exchange Commission (the "Commission"), the acquisition of the assets and
assumption of certain liabilities for all of the Founding Affiliated Practices
pursuant to the Reorganizations is accounted for by the Company at the
transferors' historical cost basis with the shares of Common Stock to be issued
in those transactions being valued at the historical cost of the non-monetary
assets acquired net of liabilities assumed. Each of the securityholders of the
Founding Affiliated Practices is deemed to be a promoter of this offering. The
cash consideration will be reflected as a dividend by APPI to the owners of the
Founding Affiliated Practices. SAB No. 48 will not be applicable to any
acquisitions made by the Company subsequent to this offering. It is currently
anticipated that the Company's future acquisitions of certain assets and
liabilities of Affiliated Practices may result in substantial annual non-cash
amortization charges for intangible assets in the Company's statements of
operations.
    
 
     An integral part of the Company's business strategy is to grow through
acquisitions and to expand the Affiliated Practices. Although the Company is
currently engaged in discussions with several such potential acquisition
candidates, except as disclosed in this Prospectus, the Company has not entered
into any letters of intent or definitive purchase agreements with respect to any
such acquisitions. No assurance can be provided that any such acquisitions will
be consummated.
 
RESULTS OF OPERATIONS
 
   
     APPI has conducted no significant operations to date and will not conduct
significant operations until the Reorganizations and this offering are
completed. APPI has incurred and continues to incur various legal, accounting,
travel and marketing costs in connection with the Reorganizations and this
offering. As of June 30, 1997, such expenses had been funded primarily by the
proceeds received from the issuance of $3.5 million in Convertible Notes. In
addition, during 1996, APPI borrowed $0.4 million in the form of notes from its
stockholders. As of June 30, 1997, these notes were fully repaid.
    
 
     APPI has recorded a full valuation allowance against its deferred tax
assets because of its current financial condition, its limited operating history
and its operating losses recorded to date. If the Company does achieve
profitability in the future, the valuation allowance will be reduced by a credit
to income.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     If the Reorganizations and this offering had occurred on June 30, 1997, the
Company would have had pro forma working capital of $17.2 million (assuming an
initial offering price of $15.00 per share and after giving effect to the use of
proceeds from this offering in the manner set forth in "Use of Proceeds").
    
 
   
     The Company anticipates making capital expenditures during the remainder of
1997 of approximately $7.0 million, primarily for the purchase of imaging and
teleradiology equipment. In addition to these capital expenditures, the Company
is working to establish relationships with third-party vendors regarding the
potential purchase and implementation of management information systems that
could involve additional expenditures of approximately $2.4 million during the
remainder of 1997. The Company also expects to make acquisitions of the assets
of practices during 1997 that will involve the use of cash and Common Stock.
    
 
   
     The Company has executed the $115 million Credit Facility with GE Capital,
as agent, and other lenders, which Credit Facility is expected to become
effective upon completion of this offering and consummation of the
Reorganizations. Under the terms of the Credit Facility, 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 three
    
 
                                       27
<PAGE>   29
 
   
times the consolidated EBITDA of the Company giving pro forma effect to
acquisitions made with such borrowings. At the Company's option, the interest
rate shall be (i) an adjusted LIBOR rate plus an applicable margin which can
vary from 1.0% to 1.75% or (ii) the prime rate plus an applicable margin which
can vary from 0 to .75%. In each case the applicable margin varies based on
financial ratios maintained by the Company. The Credit Facility will include
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, as defined). Borrowings under the Credit
Facility are secured by all Service Agreements to which APPI is or becomes a
party and a pledge of the stock of APPI's subsidiaries.
    
 
   
     Upon consummation of this offering, the Company intends to borrow
approximately $17,000,000 under the Credit Facility to refinance existing
indebtedness of the Founding Affiliated Practices and fund working capital. The
Company anticipates that it will use future borrowings under the Credit Facility
to fund capital expenditures for the Affiliated Practices, make acquisitions and
for general corporate purposes.
    
 
   
     The availability of the Credit Facility is subject to satisfaction of a
number of closing conditions, including consummation of this offering with Net
Proceeds to the Company of at least $60 million, consummation of the
Reorganizations and other closing and borrowing conditions. There can be no
assurance that borrowing capacity under the Credit Facility will be available to
the Company when needed.
    
 
   
     The Company anticipates that funds generated from this offering, after
giving effect to the use of proceeds from this offering in the manner set forth
in "Use of Proceeds," funds generated from operations, cash and cash
equivalents, and funds expected to be 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 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 Company intends to call the Convertible Notes for redemption upon
completion of this offering. Upon the call, the Convertible Notes may, at the
election of the noteholders of at least 50% of the outstanding principal amount,
be converted into shares of Common Stock at a conversion price of $8.00 per
share. The Company believes that all of the holders of the Convertible Notes
will elect to convert to Common Stock prior to the redemption. In the event that
some or all of the holders of the Convertible Notes fail to convert their
respective Convertible Notes into Common Stock, the Company intends to make the
redemption payment of up to $3,500,000 plus accrued interest with the proceeds
from the proposed Credit Facility.

                                    BUSINESS
 
GENERAL
 
   
     The Company was formed in April 1996 to provide physician practice
management and administrative services to radiology practices with a focus on
the development, consolidation and management of integrated radiology and
imaging center networks. Upon completion of this offering, the Company will
provide practice management services to seven radiology practices consisting of
223 physicians practicing at 42 hospitals and 65 diagnostic imaging centers
("ICs") in California, Kansas, Maryland, New York and Texas. The Company will
derive its revenue from service fees paid by Affiliated Practices for
management, administrative, technical and other non-medical services provided by
the Company.
    
 
   
     The typical relationship with an Affiliated Practice is expected to involve
the acquisition by the Company of all of the non-medical assets (tangible and
intangible) of the Affiliated Practice and entry into a long-term Service
Agreement with the Affiliated Practice at the time of acquisition pursuant to
which the Company would provide a wide range of management, administrative,
technical and non-medical services in exchange for a service fee. If the
Affiliated Practice owns and operates an IC, the Company would typically acquire
all of the IC-related assets (e.g., x-ray, MRI and CT equipment). As a result,
the Affiliated Practice would rely on the Company to provide all necessary
non-medical business and administrative services and the Affiliated Practice
would continue to employ all of the professional personnel (i.e., the
radiologists) who would continue to provide professional medical services for
and on behalf of the Affiliated Practice.
    
 
     The Founding Affiliated Practices provide a wide range of diagnostic and
therapeutic services, including x-ray and fluoroscopy, magnetic resonance
imaging, computed tomography, mammography, ultrasound, nuclear medicine,
radiation oncology and interventional radiology. The Founding Affiliated
Practices were selected based on a variety of factors, including: physician and
practice credentials and reputation; competitive market position; subspecialty
mix of physicians; historical financial performance and growth potential; and
willingness to embrace the Company's vision and philosophy regarding the
provision of radiology services. The Company intends to provide Affiliated
Practices with the necessary capital resources and expertise to invest in new
technologies, complete consolidating acquisitions, implement sophisticated
management information systems, promote efficient practice patterns, develop
coordinated marketing efforts and realize purchasing economies of scale.
 
     The Company's objective is to develop integrated networks of radiology
groups and ICs that can provide wide geographic coverage and subspecialty
expertise. The Company intends to provide the networks with sophisticated
management, state-of-the-art information systems and appropriate capital for
expansion. The Company's strategy is to (i) emphasize quality service, (ii)
expand within its selected markets, (iii) improve operating efficiencies within
the Affiliated Practices and (iv) expand into new regional markets through
acquisitions of or affiliations with additional radiology practices and ICs.
 
     The Company was incorporated in Delaware in April 1996, and prior to this
offering has not conducted any significant operations. In connection with the
Reorganizations, APPI will acquire certain assets and liabilities of, and enter
into long-term Service Agreements with, the Founding Affiliated Practices.
Pursuant to the Service Agreements, the Company will provide management,
administrative, technical and non-medical business services to the Founding
Affiliated Practices in exchange for a service fee. The Service Agreements have
a 40-year term, subject to earlier termination under certain circumstances. See
"-- Service Agreements" and "Certain Transactions -- The Reorganizations."
 
INDUSTRY BACKGROUND
 
  Market Overview
 
     The Health Care Financing Administration estimates that national health
care spending in 1995 was approximately $1 trillion, including approximately
$200 billion for physician services and an additional $600 billion for health
care expenditures under the control or influence of physicians. According to the
American College of Radiology, an estimated 350 million radiological procedures
were performed in the
 
                                       29
<PAGE>   31
 
United States during 1995. Total spending on radiology services including
diagnostic imaging, interventional radiology and radiation oncology was
estimated at $56 to $70 billion according to a 1995 report prepared by SMG
Marketing Group. Diagnostic imaging, including interventional radiology
procedures, accounted for approximately 82% of the aggregate amount spent on
radiological services performed in the United States, with radiation oncology
services accounting for approximately 18%.
 
     Fees charged for diagnostic imaging, interventional radiology and radiation
oncology procedures consist generally of a technical component relating to
facilities, equipment and non-physician personnel and a professional component
consisting of fees paid to physicians for the interpretation of diagnostic
images, the performance of interventional radiology procedures and the treatment
of radiation oncology patients. Technical facilities are located within
hospitals and in approximately 2,200 outpatient centers throughout the United
States. Professional radiology services are provided by board certified
radiologists, general practitioners and other specialists. There are
approximately 3,200 radiology groups in the United States comprised of
approximately 27,000 practicing radiologists. These groups have a typical size
of six members, but vary in size up to approximately 100 physicians serving a
specific market. Approximately 88% of all radiologists perform diagnostic
procedures, including interventional radiology procedures, and approximately 12%
practice radiation oncology.
 
  Radiology
 
     In general, radiology includes diagnostic imaging, interventional radiology
and radiation oncology. Imaging procedures use energy waves to penetrate human
tissue and generate images of the body, which can be recorded on film or
digitized for display on a video monitor. Diagnostic imaging procedures are used
to diagnose diseases and physical injuries and are performed in hospitals,
physicians' offices, outpatient centers and ICs. Interventional radiology
procedures include the use of radiological methods to monitor and guide
catheters, stents, drains and needles to open clogged vessels, relieve
obstructed kidneys, perform biopsies of mass lesions, drain abscess collections
and lower pressure in certain vessels. Generally, these interventional
procedures are more time efficient, more cost-effective and less invasive than
surgical alternatives and have historically been performed in a hospital setting
to enable utilization of hospital support services. Radiation oncology
procedures use a variety of radiation sources to treat cancer and/or relieve
pain caused by certain tumors and are performed in hospitals and free-standing
outpatient centers.
 
     The principal diagnostic imaging modalities include the following, all of
which are non-invasive:
 
          General Radiology: X-Ray and Fluoroscopy. X-rays utilize roentgen rays
     to penetrate the body and record images of organs and structures on film.
     Fluoroscopy utilizes ionizing radiation combined with a video viewing
     system for real time monitoring of organs. X-ray and fluoroscopy are the
     most frequently used imaging modalities.
 
          Computed Tomography ("CT"). CT utilizes a computer to direct the
     movement of an x-ray tube to produce multiple cross sectional images of a
     particular organ or area of the body. CT is used to detect tumors and other
     conditions affecting bones and internal organs. It is also used to detect
     the occurrence of strokes, hemorrhages and infections. CT provides higher
     resolution images than conventional x-rays, but generally not as well
     defined as those produced by magnetic resonance.
 
          Magnetic Resonance Imaging ("MRI"). MRI utilizes a strong magnetic
     field in conjunction with low energy electromagnetic waves which are
     processed by a computer to produce high-resolution images of body tissue
     including the brain, spine, abdomen, heart and extremities. Unlike CT and
     conventional x-rays, MRI does not utilize ionizing radiation, which can
     cause tissue damage in high doses.
 
          Mammography. Mammography is a specialized form of radiology utilizing
     low dosage x-rays to visualize breast tissue and is the primary screening
     tool for breast cancer. Mammography procedures also include the biopsy of
     cells to assist in the diagnosis of breast cancer.
 
          Ultrasound. Ultrasound imaging utilizes high-frequency sound waves to
     develop images of internal organs, unborn fetuses and the vascular system.
     Ultrasound has widespread applications, particularly for procedures in
     obstetrics, gynecology and cardiology.

          Nuclear Medicine. Nuclear medicine utilizes short-lived radioactive
     isotopes which release small amounts of radiation that can be recorded by a
     gamma camera and processed by a computer to produce an image of various
     anatomical structures or to assess the function of various organs such as
     the heart, kidneys, thyroid and bones. Nuclear medicine is used primarily
     to study anatomic and metabolic functions.
 
  Trends In Radiology
 
     Technological Advancements. The Company believes that advances in
technology, including the development and continued enhancements of MRI, CT,
nuclear medicine, ultrasound and interventional radiology have contributed to
the growth of the diagnostic imaging industry. These technological advances have
resulted in increased professional and technical utilization and have produced
diagnostic procedures that are safer, more accurate and less-invasive than
techniques previously utilized. While traditional x-rays continue to be the
primary imaging modality based on the number of procedures performed, the use of
advanced diagnostic imaging modalities such as MRI and CT has increased rapidly
in recent years because these modalities allow physicians to diagnose a wide
variety of diseases and injuries quickly and accurately without exploratory
surgery or other surgical or invasive procedures, which are usually more
expensive, involve greater risk to the patient and result in longer
rehabilitation time. As a result, hospital days are shortened or eliminated and
time lost from work is significantly reduced. In addition, diagnostic imaging is
increasingly used as a screening tool for preventive care. The Company believes
that future technological advances will enhance the ability of radiologists to
diagnose and direct treatment, thereby lowering overall health care costs.
 
     Recent technological advancements include: magnetic resonance spectroscopy,
which can differentiate malignant from benign lesions; magnetic resonance
angiography, which can produce three-dimensional images of body parts and assess
the status of blood vessels; spiral computed tomography, which permits three-
dimensional images of body parts; monoclonal antibody studies utilizing nuclear
medicine to localize certain cancers that would otherwise be difficult to detect
or treat; and the development of teleradiology, which digitally transmits
radiological images from one location to another for interpretation. The Company
believes that the utilization of both the diagnostic and therapeutic
capabilities of radiology will continue to increase because of its
cost-effective, time-efficient and risk/benefit advantages over alternative
procedures (including surgery) and that newer technologies and future
technological advancements will result in further sub-specialization and
increased utilization of professional and technical radiological services.
 
     Reimbursement Patterns. Payment for radiology services comes primarily from
third-party payors such as private insurers (including traditional indemnity
insurance plans), managed care plans (including HMOs and PPOs) and governmental
payors (including Medicare and Medicaid). Historically, radiologists and other
physicians generally provided medical services on a fee-for-service basis. The
fee-for-service model provides few incentives for the efficient utilization of
resources and has contributed to increases in health care costs at rates
significantly higher than inflation. As managed care entities and other payors
have focused on providing care in a more cost-effective manner, they have
demanded and received significant discounts from fee-for-service rates charged
for radiological procedures. As a result, physicians have seen a decrease in per
procedure reimbursements from managed care and governmental entities for such
procedures. More recently, payors have focused on shifting more of the financial
risk for the provision of cost-effective services to providers through
capitation and other risk-sharing arrangements. Significant changes of this type
will require the Company to become more actively involved in assisting its
Affiliated Practices in developing practice guidelines and appropriateness
criteria and managing the utilization of radiological procedures.
 
     The Company believes that the shift in financial risk from payors to
providers decreases the attractiveness of under-utilized imaging equipment
within a general practitioner's office and will accelerate the centralization of
resources to high-volume centers. According to an article published in the
American Journal of Radiology in 1993, approximately 64% of all radiological
procedures (primarily x-rays and ultrasound) performed in freestanding ICs and
physicians' offices were performed by non-radiologist physicians including
internists, family and general practitioners and orthopedists. The Company
believes that the general diagnostic imaging services performed by
non-radiologists may be directed to radiologists by managed care entities
seeking to have services performed at the lowest overall cost. As a result, the
Company believes that managed care
 
                                       31
<PAGE>   33
 
entities, provided with utilization reports, will focus on reducing costs by
shifting radiological procedures performed by non-radiologists to radiologists.
 
     Consolidation of ICs. Concurrent with the growth of managed care and strict
controls on Medicare reimbursement for inpatient costs, diagnostic imaging
services began to shift from hospital settings to ICs in the early 1980s. While
many of these ICs were developed by physicians and hospitals, a subsequent
change in federal law restricted the referral of patients by a physician to a
facility in which the physician maintained an ownership interest. As a result,
many physicians sold their interests in ICs to hospitals, radiologists and
companies engaged exclusively in the ownership, operation and management of ICs.
The Company believes that many of these entities have and will continue to
consolidate the ownership of ICs.
 
     Referral Sources. Non-radiologists, including specialists and primary care
physicians, direct the utilization of radiology services. Most industry
marketing has been focused on developing relationships with these referring
physicians. As more patients move to managed care plans, the Company believes
physicians will have fewer referral options for diagnostic imaging procedures.
In addition, the Company believes that managed care entities will increasingly
demand that providers of radiology services share in the financial risks
associated with providing services for the lives covered by the managed care
entities. As the choices for radiology referrals decrease, the Company believes
that quality of care, subspecialty expertise and patient and referring physician
satisfaction will be important factors in determining referral patterns.
 
     Trends in Radiology Organizations. The trends toward managed care, cost
containment and health care consolidation have combined to limit the number of
positions available and the salaries paid to radiologists. In addition, small
independent physician groups and individual practices are typically at a
competitive disadvantage to larger associations or networks of physicians
because they lack the capital necessary to (i) expand the geographic coverage of
the practice and the imaging modalities offered, (ii) develop state-of-the-art
information systems and (iii) purchase costly new imaging technologies, each of
which can improve quality of care and reduce costs. Generally, they also lack
the cost accounting and quality management systems necessary to allow physicians
to price and monitor complex risk-sharing arrangements with third-party payors.
Additionally, small to medium-sized groups and individual practices often do not
have contractual ties with other providers nor do they have the ability to offer
a broad range of subspecialty imaging services. Small practices often have
higher operating costs (since overhead must be spread over a relatively small
revenue base) and minimal vendor purchasing power. In order to remain
competitive in the changing medical service environment, radiologists are
beginning to affiliate with or create larger organizations by adding
radiologists to their groups, creating or joining a network or an independent
physician association or affiliating with a physician practice management entity
such as the Company.
 
BUSINESS STRATEGY
 
     The Company's objective is to develop integrated networks of radiology
groups and ICs that can provide wide geographic coverage and subspecialty
expertise. The Company intends to provide the networks with sophisticated
management, state-of-the-art information systems and appropriate capital for
expansion. The Company's strategy is to (i) emphasize quality service, (ii)
expand within its selected markets, (iii) improve operating efficiencies within
the Affiliated Practices and (iv) expand into new regional markets through
acquisitions of or affiliations with additional radiology practices and ICs.
 
  Emphasize Quality Service
 
     The Company plans to make patient service and referring physician
satisfaction a key element of its strategy. The Company intends to form regional
service networks and invest in advanced teleradiology technologies to provide
greater geographic coverage, improve response time and increase overall patient
accessibility. The Company will seek to offer, through its Affiliated Practices,
subspecialty expertise such as interventional radiology and radiation oncology
to address the full range of radiology service needs of patients, referring
physicians, hospitals and payors. The Company also intends to provide capital to
the Affiliated Practices to upgrade existing imaging equipment and purchase
equipment for newer modalities. In addition, the Company plans to implement
information systems which will provide the Company's payors and referral
 
                                       32
<PAGE>   34
 
sources with outcomes data, cost analyses, utilization management data and other
analyses, in each case with the objective of maximizing patient, referring
physician, hospital and payor satisfaction.
 
  Expand Within Existing Regional Markets
 
   
     A key element of the Company's strategy is to expand and leverage the
resources and capabilities of its Affiliated Practices to offer high-quality,
comprehensive and competitively priced diagnostic, interventional and
therapeutic radiology programs within selected markets. The Company believes
that cost-conscious payors, particularly those interested in utilizing or
implementing risk-sharing or global capitation arrangements, will prefer to
contract with a single provider for a full range of radiology services within
select geographic markets. The Company plans to acquire and affiliate with
additional complementary radiology practices and, when feasible, acquire,
operate and manage ICs to broaden the range of, and increase the capacity to
deliver, services within its markets. The Company intends to market its
comprehensive service offerings and geographic coverage to obtain payor
contracts.
    
 
  Improve Operating Efficiencies
 
     The Company intends to utilize its management infrastructure and the
collective knowledge of and information generated by its Affiliated Practices to
identify and promote practice operating efficiencies that benefit all Affiliated
Practices. The Company believes that information technology is critical to such
efforts and plans to implement sophisticated management and financial
information systems to obtain and disseminate information relating to practice
patterns, equipment utilization, facilities and personnel and operating
profitability. The Company believes such information will enable Affiliated
Practices to enhance quality of care, increase revenue, improve cash management
and more effectively control costs. The Company believes that the establishment
of systems that promote "best practices" and operating efficiencies can provide
the Company and its Affiliated Practices with a competitive advantage in
negotiating and obtaining managed care contracts. In addition, the Company
intends to capitalize on the size and purchasing power of the combined
Affiliated Practices to take advantage of economies of scale and to reduce the
cost of administering and operating such practices.
 
  Expand into New Markets
 
     The Company plans to expand into new geographic markets by acquiring and
affiliating with profitable radiology practices that have strong reputations and
competitive positions in their local markets. The Company intends to focus on
markets where there are significant prospects for physician networking and
practice consolidation, high patient-provider ratios and favorable overall
economic conditions. The Company intends to focus on acquiring and affiliating
with platform practices allowing the Company to pursue the expansion strategy
discussed above. The Company believes that it will be attractive to potential
Affiliated Practices because of its (i) exclusive focus on radiology, (ii)
governance structure which promotes physician input, (iii) service fee structure
which aligns the Company's revenue growth incentives with those of the
Affiliated Practices and (iv) transaction structure which permits physicians to
become stockholders of the Company and further aligns the interests of the
Company and the Affiliated Practices. The Company expects that its Affiliated
Practices will be instrumental in identifying potential acquisitions and
affiliations with future Affiliated Practices or ICs.
 
AFFILIATION STRUCTURE
 
     APPI was formed to provide physician practice management and administrative
services to radiology practices and to own, operate and manage ICs. The
Company's business model is based on a "partnership" with its Affiliated
Practices in which the Company manages the non-medical functions of the
Affiliated Practices in a manner that promotes physician participation and input
in areas such as practice enhancement and operating efficiencies, marketing and
long-term strategy development. The Company believes that its partnering
approach (i.e., shared ownership, economic interest and governance) enables
physicians to provide input in the management and affairs of their practice and
aligns the interests of physicians in the Affiliated Practices with those of the
Company in promoting practice growth and operating efficiencies. The Company
 
                                       33
<PAGE>   35
 
believes its model will be attractive to potential practice acquisition
candidates. For a discussion of the contractual arrangements between the Company
and its Affiliated Practices, see "Business -- Service Agreements."
 
     In connection with the Reorganizations, the Company will acquire certain
tangible and intangible assets and assume certain liabilities of the Founding
Affiliated Practices. The Company will pay the purchase price for such
transactions in shares of its Common Stock and, to a lesser extent, cash. At the
time of the Reorganizations, the Company will enter into a 40-year Service
Agreement with each Founding Affiliated Practice pursuant to which the Company
will provide a wide range of management, administrative, technical and
non-medical services. For providing services under the Service Agreement, the
Company will receive a fee which is structured to align the interests of the
Company and the Founding Affiliated Practices. Additionally, the Service
Agreements restrict the Founding Affiliated Practices from competing with the
Company and other Affiliated Practices within a specified geographic area during
the term of the Service Agreements and also require each Affiliated Practice to
obtain and enforce similar restrictive covenants with the full-time physicians
affiliated with their practices. As part of its growth strategy, the Company
intends to acquire the assets of and enter into similar long-term Service
Agreements with additional radiology practices based on the partnership model it
has established with the Founding Affiliated Practices.
 
   
     Additionally, pursuant to the Reorganizations, the Company will acquire
interests in certain joint venture arrangements currently held by the Founding
Affiliated Practices and certain physicians associated with the Founding
Affiliated Practices. The joint venture arrangements represent partnerships with
various hospitals or health systems serviced by certain of the Founding
Affiliated Practices and were formed for the purpose of owning and operating
ICs. Professional services at the joint venture ICs are performed by certain of
the Founding Affiliated Practices. With respect to the six joint venture
interests acquired from Advanced Radiology, LLC, the Company will acquire a 50%
interest in five joint ventures and a controlling interest in one joint venture.
With respect to M&S X-Ray Practices, the Company will acquire a controlling
interest in one joint venture and a minority interest in three joint ventures.
With respect to Radiology and Nuclear Medicine, P.A., the Company will acquire a
minority interest in one joint venture.
    
 
     The Company believes a shared governance approach is critical to the
long-term success of a physician practice management company. While the Company
will have the primary responsibility for managing the non-medical functions of
its Affiliated Practices, it will operate within a governance structure which
promotes physician involvement in the direction and management of the Affiliated
Practices and the Company. This will be accomplished by the Company and each
Affiliated Practice establishing a Joint Planning Board consisting of three to
six members. The Joint Planning Boards will have responsibility for (i)
establishing payor contracting guidelines, (ii) making recommendations with
respect to operating budgets and capital expenditures and (iii) developing
marketing strategies and long-term objectives for their respective practices.
The Company believes the Joint Planning Boards will promote participation by
physicians in the overall management of their practices and serve as a means for
the Company and its Affiliated Practices to communicate effectively and exchange
information. In addition, the Company intends to establish a Physician Advisory
Board, the primary focus of which will be to enhance the quality of services
provided by the Company and its Affiliated Practices. The Physician Advisory
Board will consist of 9 to 12 practicing physicians from the Affiliated
Practices and will be chaired by the Company's Senior Vice President of
Physician Affairs. This board will serve as a forum in which members can discuss
and make recommendations regarding clinical applications, practice protocols,
appropriateness criteria, utilization guidelines, best practices and managed
care issues. Recommendations will be communicated to all Affiliated Practice
physicians, however, the adoption of such recommendations will be at the
discretion of the Affiliated Practices.
 
OPERATIONS AND DEVELOPMENT
 
  General
 
     The Founding Affiliated Practices consist of seven radiology practices,
comprised of 223 radiologists, located in five states. All of the Founding
Affiliated Practices provide professional services, which consist of the
supervision, performance and interpretation of radiological procedures in
hospitals, ICs or other settings.
 
                                       34
<PAGE>   36
 
As a result of the Reorganizations, the Company will own and operate 54 ICs and
operate and manage 11 additional ICs through joint venture relationships. In
addition, the Founding Affiliated Practices currently provide professional
radiology services to 42 hospitals. In the aggregate, the Founding Affiliated
Practices will provide all subspecialty diagnostic and interventional radiology
and radiation oncology services. Substantially all of the 223 radiologists are
board certified.
 
     The number and type of modalities offered at the Company's owned, operated
or managed ICs are determined by the demand for such services within their
respective market areas. Presently, 55 of these ICs offer multiple modalities
including various combinations of MRI, CT, mammography, ultrasound, nuclear
medicine, fluoroscopy and traditional radiography. By offering a wide spectrum
of imaging modalities, the Company intends to market itself as a full-service
provider of diagnostic imaging services. In addition to the ICs, the Founding
Affiliated Practices provide professional services to hospitals, hospital
outpatient facilities, physicians' offices, mobile imaging units and nursing
homes.
 
     The Company intends to expand its operations into new markets principally
through the acquisition of platform practices. Prior to entering a new market,
the Company will consider various factors including the population,
demographics, market potential, competitive environment, degree of managed care
penetration, supply of radiologists, existing imaging services and general
economic conditions within the market. The Company will seek to identify and
affiliate with group practices which have a significant market presence or which
the Company believes can achieve such a presence in the near term. The Company
will identify potential acquisition candidates through a variety of means,
including targeted contacts of radiologists by the Company, participation in
professional conferences, referrals from Affiliated Practices and direct
inquiries by radiologists.

  Information Management
 
   
     The Company believes that integrated radiology networks require extensive
information management systems to effectively manage operations, compete for
managed care contracts and achieve standardization and economies of scale. The
Company intends to create a network infrastructure, including a Financial
Accounting System ("FAS") and Executive Information System ("EIS"), which may
utilize components of the Founding Affiliated Practices' existing information
systems. The Company is also evaluating the feasibility of deploying other
standard information systems, including a managed care system and a radiology
information system.
    
 
     The Company intends to implement its initial information management plans
in two phases. During the first phase, the Company intends to focus on building
basic infrastructure. Specifically, the Company intends to create a network
communications infrastructure and implement the FAS during the remainder of
1997. The network communications infrastructure will provide access to the FAS
and EIS, facilitate the gathering of key operational data and increase internal
communications capabilities through the enterprise-wide deployment of standard
office automation applications. The Company expects that the network
infrastructure will provide the foundation for the sharing and utilization of
certain information among the Affiliated Practices and the Company. The network
will be created with standard components to be managed centrally in order to
minimize the need for local information systems personnel.
 
     The Company intends to deploy the FAS to facilitate timely and accurate
financial reporting throughout the Company. Specifically, the Company intends to
deploy general ledger, accounts payable, payroll and materials management
systems at each of the Affiliated Practices. The FAS will be designed to
facilitate the consistent, efficient reporting of financial information across
all practices using one standard chart of accounts with a single set of
accounting practices and financial controls. The Company expects that the
deployment of the FAS will streamline and simplify the financial reporting
process and will provide a tool for managing practice efficiency benchmarks.
 
   
     During phase two, the Company expects to focus on assimilating and
analyzing data from its Affiliated Practices' disparate information systems. In
this phase, the Company intends to deploy an EIS that will facilitate the
management reporting of key operational data. The Company anticipates that the
EIS will provide a repository to store pertinent encounter data and initially
will use the Affiliated Practices' practice management systems, radiology
information systems and the FAS as primary data sources. It is anticipated that
the EIS will provide variance, utilization, reimbursement efficiency and trend
analysis reporting capabilities. The Company believes that the EIS will enable
Affiliated Practices to enhance the quality of information, increase revenue,
improve operating efficiencies and more effectively control costs. There can be
no assurance that the Company will be able to implement the FAS or EIS on a
timely basis, if at all, or that these systems will produce the expected
benefits. See "Risk Factors -- Dependence on Information Systems."
    
 
SERVICE AGREEMENTS
 
     Upon consummation of the Reorganizations, the Company will be a party to a
Service Agreement with each Founding Affiliated Practice under which the Company
will become the exclusive manager and administrator of non-medical services
relating to the operation of the Founding Affiliated Practice. The following
summary of the Service Agreement is intended to be a brief description of the
standard form of the Service Agreement that the Company will be a party to with
each Founding Affiliated Practice. The Service Agreements may vary from the
description below depending on the requirements of local regulations and
negotiations with the individual Founding Affiliated Practices. The Company
expects to enter into agreements with similar provisions with Affiliated
Practices in the future.
 
   
     The service fees payable to the Company by the Affiliated Practices under
the Service Agreements vary based on fair market value, as determined in arms'
length negotiations, and the nature and extent of services provided. Where state
law allows, service fees due under the Service Agreements are derived from two
distinct revenue streams: (i) the Affiliated Practice pays a service fee based
on a negotiated percentage (Founding Affiliated Practice service fees range from
20% to 25%) of the adjusted professional revenues as defined in the Service
Agreement; and (ii) the Affiliated Practice pays a service fee based on 100% of
the adjusted technical
    
 
                                       37
<PAGE>   39
 
   
revenues as defined in the Service Agreement, which equals the fair value of the
services provided. 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. 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 non-physician costs) from physician groups revenue of the
Affiliated Practice. In addition, the Company will receive income from joint
ventures in which the Company will hold ownership interests. Revenues will be
billed by the Company on behalf of the Affiliated Practices. Payments will be
received by the Affiliated Practice and transferred to the Company on a daily
basis. On a monthly basis the Company will calculate the amount of service fees
due and remit to the Affiliated Practices an amount equal to the difference
between the net revenues of the Affiliated Practice and the service fees
calculated by the Company. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Overview."
    
 
   
     Set forth below is a sample calculation of the service fees under the two
fee structures described above and the respective income statements of a
hypothetical Affiliated Practice and the Company related to such service fee
calculation. The following examples are for illustrative purposes only and do
not represent the actual or potential service fee that would be payable by any
Affiliated Practice, the operating results of any Affiliated Practice or the
relationship of revenues and expenses.

     Pursuant to the Service Agreement, the Company will, among other things:
(i) act as the exclusive manager and administrator of non-physician services
relating to the operation of the Founding Affiliated Practice, subject to
matters reserved to the Founding Affiliated Practice or referred to the Joint
Planning Board; (ii) aid in the billing of hospitals, insurance companies and
other third-party payors and collect on behalf of the Founding Affiliated
Practice the fees for professional medical and other services rendered by the
Founding Affiliated Practice; (iii) provide, as necessary, clerical, accounting,
purchasing, payroll, legal, bookkeeping and computer services and personnel,
information management, preparation of certain tax returns and medical
transcribing services; (iv) supervise and maintain custody of substantially all
files and records; (v) provide facilities for the Founding Affiliated Practice;
(vi) prepare, in consultation with the Joint Planning Board and the Founding
Affiliated Practice, all annual operating and capital budgets; (vii) order and
purchase inventory and supplies as necessary; (viii) implement, in consultation
with the Joint Planning Board and the Founding Affiliated Practice, national and
local public relations or advertising programs; (ix) provide financial and
business assistance in the negotiation, establishment, supervision and
maintenance of contracts and relationships with managed care and other similar
providers and payors; and (x) assist the Founding Affiliated Practice with
obtaining medical malpractice insurance for its physicians and other medical
professionals.
 
   
     The Service Agreements require the Company and each Founding Affiliated
Practice to establish a Joint Planning Board consisting of not less than three
nor more than six members; two designees of the Company (each with one vote) and
no less than one or more than four designee(s) of the Founding Affiliated
Practice (representing two votes in the aggregate). Each Joint Planning Board
will have responsibilities that include developing long-term strategic
objectives relating to practice expansion and payor contracting guidelines,
promoting practice efficiencies, recommending capital expenditures and generally
serving as a means by which the Company and each of the Founding Affiliated
Practices will communicate and exchange information. The Company intends to
continue to establish Joint Planning Boards in the future, some of which may be
on a regional level.
    
 
   
     Under the Service Agreements, each Founding Affiliated Practice will remain
responsible for (i) hiring and compensating its physicians and certain other
medical professionals, (ii) the licensing, credentialling and certification
necessary to conduct its practice, (iii) obtaining and maintaining medical
malpractice insurance for the professional entity and its physician employees,
(iv) providing professional radiological services and (v) complying with federal
and state laws, regulations and other ethical standards applicable to the
practice of radiology. Pursuant to the Service Agreements, the Founding
Affiliated Practices will maintain full control over the provision of
professional radiological services. The Company will not engage in the practice
of medicine or provide professional radiological services. In addition, the
Service Agreements with the Founding Affiliated Practices also contain
provisions whereby both the Company and each Founding Affiliated Practice have
agreed to certain restrictions on accepting or pursuing radiology opportunities
within a 15-mile radius (decreasing to 10 miles upon the expiration of 12
months) of any of the Company's owned, operated or managed ICs at which the
Founding Affiliated Practice provides professional radiology services or any
hospital at which a Founding Affiliated Practice provides on-site professional
radiology services. Each Service Agreement also restricts the applicable
Founding Affiliated Practice from competing with the Company and other
Affiliated Practices within a specified geographic area during the term of such
Service Agreement. In addition, the Service Agreements require the Founding
Affiliated Practices to enter into and enforce agreements with the stockholders
and full-time radiologists at each Founding Affiliated Practice (subject to
certain exceptions) that include covenants not to compete with the Company for a
period of two years after termination of employment.
    
 
     The Service Agreements are for an initial term of 40 years, with automatic
extensions of five years unless notice of termination is given. The Service
Agreements may be terminated by either party if (i) the other party (a) files a
petition in bankruptcy or other similar events occur or (b) defaults in the
performance of a material duty or obligation, which default continues for a
specified period after notice or (ii) an opinion is rendered by a law firm of
nationally-recognized expertise in health care law that a material term of the
Service Agreement is in violation of applicable law (or a court or regulatory
agency finds as such) and such violation cannot be cured.
 
                                       39
<PAGE>   41
 
     Each Service Agreement may also be terminated by the Company if the
Founding Affiliated Practice or a physician employee engages in conduct, or is
formally accused of conduct, for which the physician employee's license to
practice medicine reasonably would be expected to be subject to revocation or
suspension or is otherwise disciplined by any licensing, regulatory or
professional entity or institution, the result of any of which (in the absence
of termination of such physician or other action to monitor or cure such act or
conduct) does or reasonably would be expected to materially adversely affect the
Founding Affiliated Practice. In addition, the Company may terminate each
Service Agreement with any Founding Affiliated Practice if, during the first
five years of the Service Agreement, more than 33 1/3% of the total number of
physicians employed or retained by such practice are no longer employed or
retained by such practice other than because of certain events, including death,
permanent disability, pre-qualified retirement or involuntary loss of hospital
contracts or privileges.
 
     Upon termination of a Service Agreement with a Founding Affiliated
Practice, depending upon the termination event, the Company may have the right
to require such Founding Affiliated Practice to purchase and assume, or the
Founding Affiliated Practice may have the right to require the Company to sell,
assign and transfer to it, the assets and related liabilities and obligations
associated with the professional and technical radiology services provided by
the Founding Affiliated Practice immediately prior to such termination. The
purchase price for such assets, liabilities and obligations will be the lesser
of fair market value thereof or the return of the consideration received in the
Reorganization; provided, however, that the purchase price shall not be less
than the net book value of the assets being purchased.
 
PRACTICE MARKETING
 
     The Company intends to focus its marketing efforts on referring physicians,
hospitals and managed care organizations. Prior to the Reorganizations, the
Founding Affiliated Practices' marketing efforts were based primarily upon the
professional reputations and individual efforts of such practices and its
radiologists. The Company believes there is an opportunity to capitalize on the
professional reputations of the Founding Affiliated Practices by applying
professional sales and marketing techniques to increase the Affiliated
Practices' volume of business and expand the potential geographic market for
each Affiliated Practice beyond its local physician community.
 
     In addition, the Company will seek to secure new contracts and expand
existing contracts with managed care organizations for the provision of
radiology services. The Company is prepared to negotiate flexible arrangements
with managed care organizations on behalf of the Affiliated Practices.
 
GOVERNMENT REGULATION AND SUPERVISION
 
  General
 
     The health care industry is highly regulated, and there can be no assurance
that the regulatory environment in which the Company operates will not change
significantly in the future. The ability of the Company to operate profitably
will depend in part upon the Company, the Affiliated Practices and their
affiliated physicians obtaining and maintaining all necessary licenses,
certificates of need and other approvals and operating in compliance with
applicable health care regulations. The Company believes that health care
regulations will continue to change and, therefore, intends to monitor
developments in health care law and the Company expects to modify its operations
from time to time as the business and regulatory environment changes. There can
be no assurance that the Company will be able to modify its operations so as to
address changes in the regulatory environment.
 
  Licensing and Certification Laws
 
   
     Every state imposes licensing requirements on individual physicians and on
facilities operated, or services performed, by physicians and others. In
addition, federal and state laws regulate HMOs and other managed care
organizations with which Affiliated Practices or their affiliated physicians may
have contracts. Many states require regulatory approval, including certificates
of need and/or licensing, before establishing or expanding certain types of
health care facilities, offering certain services or making expenditures in
excess of
    
 
                                       40
<PAGE>   42
 
statutory thresholds for health care equipment, facilities or programs. In
connection with the expansion of existing operations and the entry into new
markets, the Company, the Affiliated Practices or their affiliated physicians
may become subject to additional regulation.
 
  Fee-Splitting; Corporate Practice of Medicine
 
     The laws of many states (including each of the states in which the Founding
Affiliated Practices are located) prohibit physicians from splitting fees with
non-physicians and prohibit non-physician entities from practicing medicine.
These laws vary from state to state and are enforced by the courts and by
regulatory authorities with broad discretion. Although the Company intends to
structure its proposed operating structures and methods as described in this
Prospectus so as to comply with existing applicable laws, the Company's business
operations have not been the subject of judicial or regulatory interpretation.
There can be no assurance that a review of the Company's business by courts or
regulatory authorities will not result in determinations that could adversely
affect the operations of the Company or that the health care regulatory
environment will not change so as to restrict the Company's planned operations
and expansion. In addition, the regulatory framework of certain jurisdictions
may limit the Company's expansion into such jurisdictions if the Company is
unable to modify its operational structure to conform with such regulatory
framework.
 
  Medicare Physician Payment System
 
     The Company believes that regulatory trends in cost containment will
continue to result in a reduction from historical levels in per-patient revenue
for medical practices. The federal government has implemented, through the
Medicare program, the RBRVS payment methodology for physician services. The
RBRVS is a fee schedule that, except for certain geographical and other
adjustments, pays similarly situated physicians the same amount for the same
services. The RBRVS is adjusted each year and is subject to increases or
decreases at the discretion of Congress. To date, the implementation of the
RBRVS has reduced payment rates for certain of the procedures historically
provided by the Founding Affiliated Practices. BBA 97 provides for reductions in
the rate of growth of payments for physician services, including services
historically provided by the Affiliated Practices, in the amount of $5.3 billion
over a five-year period ending in 2002. In addition, BBA 97 provides for the
implementation of a resource-based methodology for payment of physician practice
expenses under the physician fee schedule over a four-year period beginning in
1999. Adoption of this methodology is expected to reduce payments for services
historically provided by the Affiliated Practices. There can be no assurance
that any reduced operating margins could be offset by the Company through cost
reductions, increased volume, the introduction of additional procedures or
otherwise. Private third-party payors and Medicare and Medicaid have increased
their use of managed care as a means of cost containment. Increasingly, private
third-party payors negotiate discounts from established physician and hospital
charges or require capitation or other risk sharing arrangements as a condition
of patient referral to physician groups such as the Affiliated Practices. BBA 97
also includes provisions designed to increase the enrollment of Medicare and
Medicaid participants in managed care programs. The inability of the Company to
negotiate satisfactory arrangements with managed care companies would have a
material adverse effect on the Company's business, financial condition and
results of operation.
 
     Rates paid by non-governmental insurers, including those that provide
Medicare supplemental insurance, are based on established physician and hospital
charges and are generally higher than Medicare payment rates. A change in the
makeup of the patient mix of the medical practices that results in a decrease in
patients covered by private insurance plans could adversely affect the Company's
revenue and income.
 
     Medicare and Medicaid have increased their use of managed care as a means
of cost containment. As with private third party payors, Medicare and Medicaid
managed care contractors negotiate discounts from established physician and
hospital charges or require capitation or other risk sharing arrangements as a
condition of patient referral to physician groups such as the Affiliated
Practices. BBA 97 includes provisions designed to increase the enrollment of
Medicare and Medicaid participants in managed care programs. The inability of
the Company to negotiate satisfactory arrangements with Medicare and Medicaid
managed care contractors could have a material adverse effect on the Company's
business, financial condition and results of operation.

  Medicare and Medicaid Fraud and Abuse
 
   
     Federal law prohibits the offer, payment, solicitation or receipt of any
form of remuneration in return for, or in order to induce, (i) the referral of a
person, (ii) the furnishing or arranging for the furnishing of items or services
reimbursable under the Medicare, Medicaid or other governmental programs or
(iii) the purchase, lease or order or arranging or recommending purchasing,
leasing or ordering of any item or service reimbursable under the Medicare,
Medicaid or other governmental programs. Pursuant to this anti-kickback law, the
federal government has recently announced a policy of increased scrutiny of
joint ventures and other transactions among health care providers in an effort
to reduce potential fraud and abuse relating to Medicare costs. The
applicability of these provisions to many business transactions in the health
care industry has not yet been subject to judicial and regulatory
interpretation. Noncompliance with the federal anti-kickback legislation can
result in exclusion from the Medicare, Medicaid, or other governmental programs
and civil and criminal penalties.
    
 
   
     The Company believes that although it will receive fees under the Service
Agreements for management and administrative services, it is not in a position
to make or influence referrals of patients or services reimbursed under the
Medicare, Medicaid or other governmental programs to Affiliated Practices or
their affiliated physicians, or to receive such referrals. Such service fees are
intended by the Company to be consistent with fair market value in arms' length
transactions for the nature and amount of management and administrative services
rendered. For these reasons, the Company does not believe that fees payable to
it should be viewed as remuneration for referring or influencing referrals of
patients or services covered by such programs as prohibited by statute. If,
however, the Company is deemed to be in a position to make, influence or receive
referrals from or to physicians, or the Company is deemed to be a provider under
the Medicare or Medicaid programs, the operations of the Company could be
subject to scrutiny under federal and state anti-kickback and anti-referral laws
and the Company's operations could be materially and adversely affected.
    
 
     Significant prohibitions against physician referrals have been enacted by
Congress. These prohibitions, commonly known as "Stark II," amended prior
physician self-referral legislation known as "Stark I" by dramatically enlarging
the field of physician-owned or physician-interested entities to which the
referral prohibitions apply. Stark II prohibits a physician from referring
Medicare or Medicaid patients to an entity providing "designated health
services", including without limitation radiology services, in which the
physician has an ownership or investment interest, or with which the physician
has entered into a compensation arrangement. The penalties for violating Stark
II include a prohibition on payment by these government programs and civil
penalties of as much as $15,000 for each violative referral and $100,000 for
participation in a "circumvention scheme." The Company believes that although it
will receive fees under the Service Agreements for management and administrative
services, it is not in a position to make or influence referrals of patients.
 
     In addition, the Company intends to structure its acquisition of the assets
of existing practices so as to not violate the anti-kickback and Stark II laws
and regulations. Specifically, the Company believes the consideration paid by
the Company to physicians to acquire the tangible and intangible assets
associated with their practices is consistent with fair market value in arms'
length transactions and not intended to induce the referral of patients. Should
this practice be deemed to constitute an arrangement designed to induce the
referral of Medicare or Medicaid patients, then the Company's acquisitions could
be viewed as possibly violating anti-kickback and anti-referral laws and
regulations. A determination of liability under any such laws could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
   
     Federal regulatory and law enforcement authorities have recently increased
enforcement activities with respect to Medicare and Medicaid fraud and abuse
regulations and other reimbursement laws and rules, including laws and
regulations that govern the Company's contemplated activities. There can be no
assurance that the Company's contemplated activities will not be investigated,
that claims will not be made against the Company or that these increased
enforcement activities will not directly or indirectly have an adverse effect on
the Company's business, financial condition and results of operation.

  HealthCare Reform Initiatives
 
     In addition to existing government health care regulation, there have been
numerous initiatives on the federal and state levels for comprehensive reforms
affecting the payment for and availability of health care services. The Company
believes that such initiatives will continue during the foreseeable future.
Certain aspects of these reforms as proposed in the past, such as further
reductions in Medicare and Medicaid payments and additional prohibitions on
physician ownership, directly or indirectly, of facilities to which they refer
patients, if adopted, could adversely affect the Company. Concern about the
potential effects of such reform measures has contributed to the volatility of
stock prices of many companies in health care and related industries and may
similarly affect the market price of the Common Stock.
 
  Compliance Program
 
     With the assistance of the Company's special health care regulatory
counsel, the Company intends to implement a program to monitor compliance with
federal and state laws and regulations applicable to health care entities. The
Company intends to appoint a compliance officer who will be charged with
implementing and supervising the Company's compliance program, which will
involve the adoption of (i) "Standards of Conduct" for its employees and
affiliates and (ii) an "Ethics Process" that will specify how employees,
affiliates and others may report regulatory or ethical concerns to the Company's
compliance officer. As part of the Ethics Process, the Company intends to
introduce various methods designed to facilitate the reporting of any regulatory
and ethical issues to the compliance officer for investigation or appropriate
corrective action. In addition, the Company intends to conduct or have its
special health care regulatory counsel conduct periodic audits of various
aspects of its operations, including the Affiliated Practices. The Company also
intends to initiate a training program designed to familiarize its employees
with the regulatory requirements and the elements of the Company's compliance
program.
 
  Insurance Laws and Regulation
 
     Certain states have enacted statutes or adopted regulations affecting risk
assumption in the health care industry, including statutes and regulations that
subject any physician or physician network engaged in risk-based contracting to
applicable insurance laws and regulations, which may include, among other
things, laws and regulations providing for minimum capital requirements and
other safety and soundness requirements. The Company believes that it and the
Affiliated Practices are currently in compliance with such insurance laws and
regulations. However, implementation of additional regulations or compliance
requirements could result in substantial costs to the Company and the Affiliated
Practices. The inability to enter into capitated or other risk-sharing
arrangements or the cost of complying with certain applicable laws that would
permit expansion of the Company's risk-based contracting activities could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
   
COMPETITION
    
 
   
     The Affiliated Practices and the Company's owned, operated or managed ICs
will compete with local radiologists and technical imaging service providers,
including for profit and non-profit hospitals and health systems, in each of the
markets served by the Company. The Company believes that changes in governmental
and private reimbursement policies and other factors have resulted in increased
competition among providers for medical services to consumers and that cost,
accessibility, quality and scope of services provided are the principal factors
that affect competition. There can be no assurance that the Affiliated Practices
and the Company's owned, operated or managed ICs will be able to compete
effectively in the markets that they serve, which inability to compete could
adversely affect the Company.
    
 
     The Company believes that the current trends in the hospital industry have
resulted in increased competition by radiology groups for hospital contracts.
Each of the Founding Affiliated Practices provides radiology services to
hospitals. These relationships can be affected through competition with other
radiology groups, the outsourcing of the radiology and imaging functions within
the hospital or closure of the hospital due to consolidation or financial
instability. There can be no assurance that each of the Founding Affiliated
 
                                       43
<PAGE>   45
 
Practices will maintain its current hospital relationships and be able to renew
or extend its current arrangements under favorable terms or effectively compete
for new relationships.
 
   
     The Company is under competitive pressures for the acquisition and
retention of the assets of, and the provision of management, technical and
administrative services to, additional radiology practices, MSOs and ICs. There
are a number of publicly-traded companies focused on owning or managing ICs,
including U.S. Diagnostic, Inc., Medical Resources, Inc., TeamHealth (a
subsidiary of MedPartners, Inc.) and Health Images (a division of HEALTHSOUTH
Corporation). The Company is aware of at least two privately-held physician
practice management companies focused on professional and technical radiology
services. Several companies, both publicly and privately held, that have
established operating histories and, in some instances, greater resources than
the Company are pursuing the acquisition of general and specialty physician
practices (including radiology in the case of TeamHealth) and the management of
such practices. Additionally, some hospitals, clinics, health care companies,
HMOs and insurance companies engage in activities similar to those of the
Company. There can be no assurance that the Company will be able to compete
effectively with such competitors for the acquisition of, or affiliation with,
radiology practices, that additional competitors will not enter the market, that
such competition will not make it more difficult or expensive to acquire the
assets of, and provide management, administrative, technical and non-medical
services to, radiology practices on terms beneficial to the Company or that
competitive pressures will not otherwise adversely affect the Company.
    
 
FACILITIES AND EMPLOYEES
 
   
     The Company's corporate headquarters are located at 2301 NationsBank Plaza,
901 Main Street, Dallas, Texas 75202, in approximately 13,349 square feet
occupied under a lease which expires on September 30, 2001. As of September 12,
1997, the Company had 19 employees and, upon consummation of the
Reorganizations, the Company expects that it will have approximately 1,100
employees, approximately 30 of which will be employed at the Company's
headquarters and regional offices and the remainder of which will be employed at
the Founding Affiliated Practices. The Company believes that its relationship
with its employees is good. See "Business -- Development and Operations."
    
 
CORPORATE LIABILITY AND INSURANCE
 
   
     The Founding Affiliated Practices maintain professional liability insurance
coverage primarily on a claims made basis. Such insurance provides coverage for
claims asserted when the policy is in effect regardless of when the events that
caused the claim occurred. As a result of the Reorganizations, the Company will
in some cases succeed to certain liabilities of the Founding Affiliated
Practices. Therefore, claims may be asserted after the Reorganizations against
the Company for events which occurred prior to the Reorganizations. Following
the Reorganizations, the Company and the Affiliated Practices intend to maintain
insurance coverage similar to the coverage previously maintained by the Founding
Affiliated Practices. On September 1, 1997, a new law became effective in the
state of Texas that permits injured patients to sue health insurance carriers,
HMOs and other managed care entities for medical malpractice. There can be no
assurance that this law will not increase the cost of liability insurance to the
Company for services provided in Texas or any other states in which the Company
does business if similar legislation is adopted in those states.
    
 
   
     The provision of medical services entails an inherent risk of professional
malpractice and other similar claims. The Company's intent is to not influence
or control the practice of medicine by physicians or have responsibility for
compliance with certain regulatory and other requirements directly applicable to
physicians and physician groups. As a result of the relationship between the
Company and the Affiliated Practices, however, the Company may become subject to
medical malpractice actions under various theories, including successor
liability. There can be no assurance that claims, suits or complaints relating
to services provided by Affiliated Practices will not be asserted against the
Company in the future. The Company maintains insurance coverage that it believes
will be adequate. The Company anticipates that such insurance will extend to
professional liability claims that may be asserted against employees of the
Company that work on site at Affiliated Practice locations. In addition,
pursuant to the Service Agreements, the Founding Affiliated Practices are
required (and the Company intends to require any other Affiliated Practices) to
maintain comprehensive professional liability insurance. The availability and
cost of such insurance is affected by
    
 
                                       44
<PAGE>   46
 
various factors, many of which are beyond the control of the Company and
Affiliated Practices. The cost of such insurance to the Company and the
Affiliated Practices may have an adverse effect on the Company's operations. In
addition, successful malpractice or other claims asserted against Affiliated
Practices or the Company that exceed applicable policy limits could have a
material adverse effect on the Company.
 
     In connection with the Reorganizations, the shareholders of the Founding
Affiliated Practices have agreed to indemnify the Company for certain claims.
There can be no assurance that the Company will be able to receive payments
under any such indemnity agreements or that the failure to fully recover such
amounts will not have a material adverse effect on the Company's business,
financial condition or results of operations.
 
     Following the Reorganizations, the Founding Affiliated Practices will be
required by the terms of the Service Agreements to maintain medical malpractice
liability insurance consistent with minimum limits mandated in their hospital
contracts or by applicable state law. It is anticipated that the minimum amounts
to be maintained will be $1 million per occurrence and $3 million in the
aggregate. The Company intends to maintain general liability and umbrella
coverage of $5 million per occurrence and $5 million in the aggregate.
Additionally, the Company will maintain workers' compensation insurance on all
employees. Coverage will be placed on a statutory basis and will respond to each
state's specific requirements.
 
LEGAL PROCEEDINGS
 
   
     The Company is not a party to any suits or complaints relating to services
provided by the Company or the Founding Affiliated Practices, although there can
be no assurances that claims will not be asserted against the Company in the
future. The Company will become subject to certain pending claims as the result
of successor liability in connection with the Reorganizations; 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.
    
 
   
     Although the Company has not been named in any of the lawsuits against a
Founding Affiliated Practice, there can be no assurance that the Company will
not subsequently be named as a defendant in one or more of these lawsuits
following consummation of the Reorganizations. Each Founding 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.

(1) All options were granted at fair market value at the date of grant, as
    determined by the Board of Directors. These options vest monthly over a
    five-year period.
 
(2) The option exercise price may be paid in shares of Common Stock owned by the
    executive officer, in cash, or in any other form of valid consideration as
    determined by the Compensation and Stock Plan Administration Committee in
    its discretion.
 
(3) The dollar amounts in these columns represent the potential realizable value
    that might be realized upon exercise of the options immediately prior to the
    expiration of their term, assuming that the market price of Common Stock
    appreciates in value from the date of grant at assumed annual rates of 5%
    and 10%. These assumed rates of appreciation are prescribed by the rules and
    regulations of the Securities and Exchange Commission, and therefore are not
    intended to forecast possible future appreciation, if any, of the price of
    the Common Stock. These numbers do not take into account provisions of
    certain options providing for termination of the option following
    termination of employment, nontransferability or vesting over periods.
 
(4) Upon consummation of this offering, this option becomes exercisable with
    respect to the greater of 50% of the shares covered thereby or the actual
    number of shares that have vested. The remainder of the shares underlying
    the option become exercisable in equal monthly installments over the
    remaining vesting period. These numbers do not take into account provisions
    of certain options providing for termination of the option following
    termination of employment, nontransferability or vesting over periods.
 
(5) As to 200,000 shares, upon consummation of this offering, this option
    becomes exercisable with respect to the greater of 100,000 shares or the
    actual number of shares that have vested, and the remainder of such shares
    become exercisable in equal monthly installments over the remaining vesting
    period. As to 30,000 shares, 10,000 shares become exercisable on the first
    anniversary of the date of grant and the remaining shares become exercisable
    in 24 equal monthly installments over the next 24 months. These numbers do
    not take into account provisions of certain options providing for
    termination of the option following termination of consulting relationships,
    cessation of services as a director of the Company or nontransferability.
 
(6) Upon consummation of this offering, this option becomes exercisable with
    respect to the greater of 25% of the shares covered thereby or the actual
    number of shares that have vested upon consummation of this offering. The
    remainder of the shares underlying the option become exercisable in equal
    monthly installments over the remaining vesting period. These numbers do not
    take into account provisions of certain options providing for termination of
    the option following termination of employment, nontransferability or
    vesting over periods.

STOCK OPTION PLAN
 
     In May 1996, the Board of Directors adopted, and the stockholders of the
Company subsequently approved, the Company's 1996 Stock Option Plan (the
"Plan"). The purpose of the Plan is to provide directors, key employees and
certain advisors with additional incentives by increasing their proprietary
interest in the Company. Under the Plan, the aggregate amount of Common Stock
with respect to which options may be granted may not exceed 3,000,000 shares.
The Plan is intended to qualify for favorable treatment under Section 16 of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), pursuant to
Rule 16b-3 promulgated thereunder ("Rule 16b-3").
 
     The Plan provides for the grant of incentive stock options ("ISOs") as
defined in Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), and non-qualified stock options (collectively, "Awards"). Following the
consummation of this offering, the Plan will be administered by the Compensation
and Stock Plan Administration Committee, which will be comprised of two or more
non-employee directors who are "disinterested" within the meaning of Rule 16b-3
(the "Committee"). Prior to the consummation of this offering, the Plan has been
administered by the Company's full Board of Directors. The Board of Directors
currently has, and the Committee will have, following consummation of this
offering, subject to the terms of the Plan, the sole authority to grant Awards
under the Plan, to construe and interpret the Plan and to make all other
determinations and take any and all actions necessary or advisable for the
administration of the Plan.
 
     All of the Company's employees, non-employee directors and advisors are
eligible to receive Awards under the Plan, but only employees of the Company are
eligible to receive ISOs. Options will be exercisable during the period
specified in each option agreement and will generally be exercisable in
installments pursuant to a vesting schedule to be designated by the Committee.
Notwithstanding the provisions of any option agreement, options will become
immediately exercisable in the event of a "change in control" (as defined in the
Plan) of the Company and in the event of certain mergers and reorganizations of
the Company. No option will remain exercisable later than ten years after the
date of grant (or five years from the date of grant in the case of ISOs granted
to holders of more than 10% of the Common Stock).
 
     The exercise price for ISOs granted under the Plan may be no less than the
fair market value of the Common Stock on the date of grant (110% of fair market
value in the case of ISOs granted to holders of more than 10% of the Company's
Common Stock). The exercise price for nonqualified options granted under the
Plan may be no less than 85% of the fair market value of the Common Stock on the
date of grant.
 
   
     The Plan provides for automatic grants of non-qualified options to purchase
30,000 shares of Common Stock to non-employee directors at the time a director
is first elected or appointed as a non-employee director, which vest with
respect to 10,000 shares on the first anniversary of the date of the grant and
the remaining
    
 
                                       51
<PAGE>   53
 
   
shares become exercisable in 24 equal monthly installments over the next 24
months, provided that such person continues to serve as a director of the
Company. In addition, upon expiration of the 36-month period following the
initial option grant to such non-employee director, such non-employee director
shall automatically be granted at each annual stockholders meeting a
non-qualified option to purchase 10,000 shares of Common Stock vesting over a
term of 12 months. Each such option entitles the director to purchase shares of
Common Stock at an exercise price equal to the fair market value of the Common
Stock on the automatic grant date. Each option shall have a ten year term
measured from the automatic grant date.
    
 
     The Plan will also permit the Company to grant stock options to advisors
and consultants of the Company who are employed as physicians of an Affiliated
Practice. Generally, such options will expire upon the termination of employment
with the Affiliated Practice or the advisory or consultant relationship with the
Company or on the day prior to the tenth anniversary of the date of grant,
whichever occurs first.
 
     The Company anticipates that upon the consummation of this offering it will
have outstanding options to purchase a total of approximately 1,681,000 shares
of Common Stock to its employees, directors and consultants. Generally, the
outstanding options are exercisable based on a monthly vesting schedule over 60
months. The Company anticipates that it will issue additional options
concurrently with or shortly following consummation of this offering. Such
options will be exercisable at the fair market value of the Common Stock on the
date of grant.
 
CASH BONUS PROGRAM
 
     In April 1997, the Board of Directors adopted, and the stockholders of the
Company subsequently approved, the Company's Cash Bonus Program (the "Program").
The purpose of the Program is to establish a bonus plan pursuant to which
eligible employees will be entitled to receive cash bonuses based on the
performance of the Company. Those employees eligible to receive cash bonuses
under the Program include the executive officers of the Company and certain key
employees whose responsibilities and activities are closely connected to the
Company's overall performance.
 
     Under the Program, cash bonuses are calculated as a percentage of each
eligible employee's base salary, with such percentage being determined based
upon the annual increase in the Company's earnings per share. In addition, each
eligible employee may receive a cash bonus based upon the achievement of certain
individual objectives and the Company's overall performance. The Program will
become effective upon consummation of this offering and will be administered by
the Compensation and Stock Plan Administration Committee of the Board of
Directors.
 
EMPLOYMENT AGREEMENTS; COVENANTS-NOT-TO-COMPETE
 
     The Company has entered into employment agreements with Gregory L. Solomon,
Mark S. Martin, Sami S. Abbasi and Paul M. Jolas, each of whom shall receive
following this offering annual salaries at the rate of $225,000, $190,000,
$190,000 and $150,000, respectively. Each employment agreement has a term of one
year with automatic successive one-year renewal periods. Each employment
agreement provides that in the event of a termination of employment by the
Company (i) other than for cause, (ii) upon disability or (iii) upon voluntary
termination by employee due to an adverse change in duties, such employee shall
be entitled to receive from the Company a payment equal to one-half of the
amount of such employee's then current annual base salary, to be paid in one
lump sum, plus a payment for all accrued but unpaid wages and expense
reimbursements. Such employment agreements provide that in the event such
employee's employment terminates following a change in control transaction (as
defined in such employment agreements) of the Company, the Company shall pay
such employee two times such employee's then current annual base salary.
 
     Each such employment agreement contains a covenant-not-to-compete with the
Company for a period of one year following termination of employment.

                              CERTAIN TRANSACTIONS
 
   
     On April 30, 1996, Derace L. Schaffer, M.D., a director of the Company,
purchased 1,000,000 shares of Common Stock in the Company for $125,000 and John
Pappajohn, a director of the Company, and his affiliates purchased 1,000,000
shares of Common Stock for $125,000. During August 1996, Mr. Pappajohn and Dr.
Schaffer advanced a total of $400,000 to the Company as loans which were repaid
on October 31, 1996, out of the proceeds of the Company's private placement of
the Convertible Notes. Dr. Schaffer owns $107,500 in principal amount of the
Convertible Notes. Mr. Pappajohn owns $250,000 in principal amount of the
Convertible Notes. On July 17, 1997, Mr. Pappajohn advanced $150,000 to the
Company as a loan bearing interest at an annual rate of 6%. On July 25, 1997,
Mr. Pappajohn and Dr. Schaffer personally guaranteed a $1,000,000 line of credit
for the benefit of the Company. The Company repaid the $150,000 loan from Mr.
Pappajohn on August 21, 1997 out of the proceeds of the $1,000,000 line of
credit. On October 3, 1997, Mr. Pappajohn advanced $100,000 to the Company as a
loan bearing interest at an annual rate of 6%. Mr. Pappajohn has agreed to loan
an additional $250,000 to the Company on the same terms prior to the
consummation of this offering, if needed by the Company. The Company intends to
repay the $100,000 and any such additional amounts borrowed from Mr. Pappajohn
upon the consummation of this offering through borrowings under the Credit
Facility.
    
 
   
     The Company and Lawrence R. Muroff, M.D., Chairman of the Board of
Directors of the Company and Senior Vice President of Physician Affairs, entered
into a consulting agreement in October 1997 pursuant to which Dr. Muroff will
receive annual compensation of $112,500 (prorated for actual months worked) in
exchange for rendering consulting services to the Company. This agreement will
become effective on the date following the consummation of this offering. In
1996, Dr. Muroff received option grants for 200,000 shares of Common Stock in
connection with his employment by the Company. In addition, he received option
grants for 30,000 shares for his services as a member of the Company's Board of
Directors. See "Business -- Management -- Option Grants During 1996." Dr. Muroff
owns $40,000 in principal amount of the Convertible Notes.
    
 
   
     The Company and Michael L. Sherman, M.D., a director nominee of the
Company, entered into a consulting agreement in August 1996 pursuant to which
Dr. Sherman received an option grant for 20,000 shares of Common Stock. In
addition, the Company and Dr. Sherman entered into a consulting agreement for
which Dr. Sherman will receive annual compensation of $100,000 commencing on the
date following the consummation of this offering. The Company has agreed to
nominate Dr. Sherman for election to the Board of Directors at the next two
annual meetings of stockholders.
    
 
   
     Mr. Solomon, the President, Chief Executive Officer and a director, owns
$40,000 in principal amount of the Convertible Notes.
    
 
   
     In connection with the Reorganizations of Advanced Radiology, LLC, Ide
Group, P.C. and Pacific Imaging Consultants, Dr. Sherman will receive 65,014
shares of Common Stock and $325,068, Dr. Schaffer will receive 94,256 shares of
Common Stock and $471,279 and Dr. Less T. Chafen will receive 31,994 shares of
Common Stock and $159,972, respectively.
    
 
REORGANIZATIONS
 
     The Company will consummate the Reorganizations simultaneously with the
closing of this offering.
 
   
     The total consideration to be paid to each Founding Affiliated Practice and
its respective securityholders in connection with the Reorganizations described
below was determined by management based on an analysis of each practice's
relative cash flows and operating cash flows before physician costs and was
determined on a consistent basis. To the extent that the initial public offering
price exceeds $14.00 per share the total consideration paid to the
securityholders of each Founding Affiliated Practice will increase in amount;
and to the extent that the initial public offering price is less than $14.00 per
share, the total number of shares issued to the securityholders of each Founding
Affiliated Practice will increase. The amount to be paid to each physician owner
is based on his/her ownership interest in the Founding Affiliated Practice.
There has been and is no relationship between the Company and any person making
any determination of amounts to be paid to the individual physician owners of
the Founding Affiliated Practices.

<PAGE>   55
 
     In connection with each Reorganization, the medical assets (e.g., payor
contracts and patient records) will be transferred to a new professional entity
that will be owned by the physicians of the respective Founding Affiliated
Practice. The Company will acquire the remaining non-medical assets from each
Founding Affiliated Practice. As a result of the Reorganizations, the Company
will not own an equity interest in the professional entities.
 
   
     The following is a brief discussion of the Reorganizations and assumes an
initial public offering price of $15.00 per share.
    
 
  Advanced Radiology, LLC
 
   
     Advanced Radiology, LLC ("Advanced") is a Maryland limited liability
company comprised of six professional association members which, in the
aggregate, have 64 physician shareholders. In June 1997, the Company entered
into agreements to acquire certain tangible and intangible assets, and assume
certain liabilities, of Advanced, pursuant to which, upon completion of the
Reorganization, the Company will have acquired all of the non-medical assets of
Advanced. Pursuant to the terms of the agreements, the securityholders of
Advanced will receive 3,562,500 shares of Common Stock valued at $53,437,500 in
the aggregate and $17,812,500 in cash.
    
 
  The Ide Group, P.C.
 
   
     The Ide Group, P.C. ("Ide") is a New York corporation which has 22
physician shareholders. In June 1997, the Company entered into an agreement to

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

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The Company's authorized capital stock consists of 50,000,000 shares of
Common Stock, par value $.0001 per share, and 10,000,000 shares of preferred
stock, par value $.0001 per share (the "Preferred Stock").
 
   
     As of the date of this Prospectus and giving effect to the Reorganizations,
the conversion of the Convertible Notes, and the completion of this offering,
the Company will have outstanding 18,321,982 shares of Common Stock (assuming an
initial public offering price of $15.00 per share) and no shares of Preferred
Stock.
    
 
COMMON STOCK
 
     The holders of Common Stock are entitled to one vote for each share on all
matters voted upon by stockholders, including the election of directors.
 
     Subject to the rights of any then outstanding shares of Preferred Stock,
the holders of the Common Stock are entitled to such dividends as may be
declared in the discretion of the Board of Directors out of funds legally
available therefor. Holders of the Common Stock are entitled to share ratably in
the net assets of the Company upon liquidation after payment or provision for
all liabilities and any preferential liquidation rights of any Preferred Stock
then outstanding. The holders of Common Stock have no preemptive rights to
purchase shares of stock of the Company. Shares of Common Stock are not subject
to any redemption provisions and are not convertible into any other securities
of the Company. All outstanding shares of Common Stock are, and the shares of
Common Stock being offered hereby will be, upon payment of consideration
therefor, fully paid and nonassessable.
 
PREFERRED STOCK
 
     Preferred Stock may be issued from time to time at the discretion of the
Board of Directors as shares of one or more series. Subject to the provisions of
the Company's Restated Certificate of Incorporation and limitations prescribed
by law, the Board of Directors is expressly authorized to adopt resolutions to
issue the shares, to fix the number of shares and to change the number of shares
constituting any series, and to provide for or change the voting powers,
designations, preferences and relative, participating, optional or other special
rights, qualifications, limitations or restrictions thereof, including dividend
rights (including whether dividends are cumulative), dividend rates, terms of
redemption (including sinking fund provisions), redemption prices, conversion
rights and liquidation preferences of the shares constituting any class or
series of Preferred Stock, in each case without any further action or vote by
the stockholders.
 
     One of the effects of undesignated Preferred Stock may be to enable the
Board of Directors to render more difficult or to discourage an attempt to
obtain control of the Company by means of a tender offer, proxy contest, merger
or otherwise, and thereby to protect the continuity of the Company's management.
The issuance of shares of Preferred Stock pursuant to the Board of Directors'
authority described above may adversely affect the rights of the holders of
Common Stock. For example, Preferred Stock issued by the Company may rank prior
to the Common Stock as to dividend rights, liquidation preference or both, may
have full or limited voting rights and may be convertible into shares of Common
Stock. Accordingly, the issuance of shares of Preferred Stock may discourage
bids for the Common Stock at a premium to, or may otherwise adversely affect,
the market price of the Common Stock.
 
CONVERTIBLE NOTES
 
     The following summaries of certain provisions of the Convertible Notes and
the Registration Rights Agreement do not purport to be complete and are subject
to, and are qualified in their entirety by reference to, all provisions of the
Convertible Notes and the Registration Rights Agreement.
 
                                       64
<PAGE>   66
 
  General
 
     The Convertible Notes represent unsecured general obligations of the
Company and are convertible into Common Stock as described below. The
Convertible Notes bear interest at the annual rate of 6%, and all accrued but
unpaid interest shall be due and payable upon the closing of this offering. In
the event the Convertible Notes are not converted into Common Stock by January
31, 1998, all accrued interest is due and payable immediately and the interest
rate will increase to the prime rate as published in The Wall Street Journal
plus 2% per annum thereafter, payable quarterly. Interest will be computed on
the basis of a 360-day year comprised of 12 30-day months. As of the date of
this Prospectus, the outstanding principal amount of the Convertible Notes was
$3,500,000.
 
  Optional Redemption
 
     The Convertible Notes are redeemable at the option of the Company, in whole
or in part, at the time of or any time after this offering. The Convertible
Notes are redeemable in their principal amount on at least 15 days' written
notice at the option of the Company, in whole or in part, together with accrued
and unpaid interest. The Company intends to call the Convertible Notes for
redemption as soon as practicable following the date of this Prospectus.
 
  Conversion Rights
 
     Upon receipt of written notice of redemption by the Company, the holders
may convert the principal of such Convertible Notes into Common Stock upon
approval of at least 50% of the outstanding principal of the Convertible Notes.
Upon conversion, holders of the Convertible Notes will receive shares of Common
Stock at the rate of one share of Common Stock for each $8.00 of Convertible
Note principal (the "Conversion Price"). Proportional adjustments shall be made
to the conversion ratio for splits, dividends, recapitalizations, and other
distributions of the Common Stock. The Conversion Price shall be reduced,
subject to several exceptions, if the Company sells any of its Common Stock for
less than $8.00 per share, to a price determined by dividing (i) an amount equal
to the sum of (A) the number of shares of Common Stock outstanding immediately
prior to such sale (including as outstanding all shares of Common Stock issuable
upon conversion of Convertible Notes) multiplied by the then existing Conversion
Price, and (B) the consideration, if any, received by the Company upon such
sale, by (ii) the total number of shares of Common Stock outstanding immediately
after the sale, including those issuable upon conversion of the Convertible
Notes. No adjustment is made to the Conversion Price for options granted to
officers, employees, directors and consultants of the Company pursuant to any
stock option plan of the Company, including the Plan.
 
     Each Convertible Note may be converted into shares of Common Stock at the
then effective Conversion Price (i) upon approval of the holders of at least 50%
of the outstanding principal amount of the Convertible Notes following the
closing of an initial public offering of the Common Stock pursuant to an
effective registration statement under the Securities Act in which the aggregate
gross proceeds received by the Company equals or exceeds $10,000,000 prior to
January 31, 1998, or (ii) upon approval of the holders of at least 50% of the
outstanding principal amount of the Convertible Notes on or after January 31,
1998.
 
     If the Company sells shares of Common Stock for less than $14.00 per share
in this offering, the conversion rate shall be adjusted so that at the time of
conversion the aggregate market value of the Common Stock into which the
Convertible Notes are converted will equal the principal of the Convertible
Notes times 1.75.
 
  Lock-up
 
     Each of the holders of the Convertible Notes has entered into a lock-up
agreement with the Company, pursuant to which each such holder has agreed with
the Company not to sell the Convertible Notes or the shares of Common Stock
issued or issuable upon conversion thereof owned by them at the time for a
period of 24 months following issuance of such Convertible Notes (which Notes
were issued between September 30 and December 31, 1996). The Company has agreed
with the Underwriters not to waive this lock-up agreement for 180 days following
the date of this Prospectus.
 
                                       65
<PAGE>   67
 
  Registration Rights
 
     The holders of the Convertible Notes have certain registration rights upon
conversion of the Convertible Notes into Common Stock. At any time from and
after 12 months following this offering, and not later than September 30, 2001,
holders owning 50% or more of the aggregate of the shares of Common Stock into
which any of the Convertible Notes have been or can be converted shall have the
right on one occasion to require the Company to prepare and file a registration
statement under the Securities Act covering such shares of Common Stock, and the
Company, at its expense, will use its best efforts to cause such registration
statement to become effective as soon as possible.
 
     In addition, the holders of Convertible Notes shall be entitled, subject to
the approval of the underwriter, to two "piggyback" registrations at the
Company's expense, as part of a registration by the Company of its shares of
Common Stock at any time subsequent to 12 months after the date of this
offering, but prior to September 30, 2001. Holders of the Convertible Notes are
granted the right on up to two occasions at the Company's expense, and prior to
September 30, 2001, to have their shares registered on Form S-3, if such form is
available for use by the Company and such holder or holders. The registration
rights are subject to a number of terms and conditions, including but not
limited to, requirements as to minimum offering size and reaching satisfactory
underwriting terms.
 
STATUTORY BUSINESS COMBINATION PROVISION
 
     The Company is subject to the provisions of Section 203 ("Section 203") of
the Delaware General Corporation Law (the "DGCL"). Section 203 provides, with
certain exceptions, that a Delaware corporation may not engage in any of a broad
range of business combinations with a person or an affiliate, or associate of
such person, who is an "interested stockholder" for a period of three years from
the date that such person became an interested stockholder unless: (i) the
transaction resulting in a person becoming an interested stockholder, or the
business combination, is approved by the Board of Directors of the corporation
before the person becomes an interested stockholder; (ii) the interested
stockholder acquired 85% or more of the outstanding voting stock of the
corporation in the same transaction that makes such person an interested
stockholder (excluding shares owned by the persons who are both officers and
directors of the corporation, and shares held by certain employee stock
ownership plans); or (iii) on or after the date the person becomes an interested
stockholder, the business combination is approved by the corporation's board of
directors and by the holders of at least 66% of the corporation's outstanding
voting stock at an annual or special meeting, excluding the shares owned by the
interested stockholder. Under Section 203, an "interested stockholder" is
defined as any person who is (i) the owner of 15% or more of the outstanding
voting stock of the corporation or (ii) an affiliate or associate of the
corporation and who was the owner of 15% or more of the outstanding voting stock
of the corporation at any time within the three-year period immediately prior to
the date on which it is sought to be determined whether such person is an
interested stockholder.
 
     A corporation may, at its option, exclude itself from the coverage of
Section 203 by amending its certificate of incorporation or bylaws by action of
its stockholders to exempt itself from coverage. The Company has not adopted
such an amendment to the Company's Restated Certificate of Incorporation or
Amended and Restated Bylaws. The applicability of Section 203 to the Company
could delay or prevent a change in control of the Company and, consequently,
could adversely affect the market price for the Common Stock.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
   
     Under Section 145 of the DGCL, the Company can indemnify its directors and
officers against liabilities they may incur in such capacities, including
liabilities under the Securities Act. The Company's Amended and Restated Bylaws
provide that the Company will indemnify its directors and officers to the
fullest extent permitted by law and require the Company to advance litigation
expenses upon receipt by the Company of an undertaking by the director or
officer to repay such advances if it is ultimately determined that the director
or officer is not entitled to indemnification. The Amended and Restated Bylaws
further provide that rights
    
 
                                       66
<PAGE>   68
 
conferred under such Bylaws do not exclude any other right such persons may have
or acquire under any bylaw, agreement, vote of stockholders or disinterested
directors or otherwise.
 
     The Company's Restated Certificate of Incorporation provides that, pursuant
to Delaware law, its directors shall not be liable for monetary damages for
breach of the directors' fiduciary duty of care to the Company and its
stockholders. This provision in the Restated Certificate of Incorporation does
not eliminate the duty of care, and in appropriate circumstances equitable
remedies such as injunctive or other forms of nonmonetary relief will remain
available under Delaware law. In addition, each director will continue to be
subject to liability for breach of the director's duty of loyalty to the Company
or its stockholders, for acts or omissions not in good faith or involving
intentional misconduct or knowing violations of law, for actions leading to
improper personal benefit to the director, and for payment of dividends or
approval of stock repurchases or redemptions that are unlawful under Delaware
law. The provision also does not affect a director's responsibilities under any
other law, such as the federal securities laws or state or federal environmental
laws.
 
     The Company intends to enter into agreements to indemnify its directors and
certain of its officers in addition to the indemnification provided for in the
Restated Certificate of Incorporation and Amended and Restated Bylaws. These
agreements, among other things, will indemnify the Company's directors and
certain of its officers for certain expenses (including attorneys' fees),
judgments, fines and settlement amounts incurred by such person in any action or
proceeding, including any action by or in the right of the Company, on account
of services as a director or officer of the Company, or as a director or officer
of any other company or enterprise to which the person provides services at the
request of the Company.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock is Chase Mellon
Shareholder Services, LLC.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     The market price of the Common Stock could be adversely affected by the
sale of substantial amounts of Common Stock in the public market following this
offering. Upon the completion of this offering, the Company will have
outstanding 18,321,982 shares of Common Stock. The 5,000,000 shares of Common
Stock to be sold in this offering will be freely tradable without restriction
under the Securities Act unless acquired by "affiliates" of the Company, as that
term is defined under the Securities Act or contractually restricted.
    
 
   
     Simultaneously with the closing of this offering, securityholders of the
Founding Affiliated Practices will receive, in the aggregate, 10,884,482 shares
of Common Stock as a portion of the consideration for their practices, which
shares will have been registered under the Securities Act. Certain other
stockholders of the Company will hold, in the aggregate, an additional 2,000,000
shares of Common Stock, none of which are being offered by this Prospectus and
none of which were acquired in transactions registered under the Securities Act.
Such unregistered shares may not be sold except in transactions registered under
the Securities Act or pursuant to an exemption from registration. The holders of
these 12,884,482 shares of Common Stock have entered into agreements with the
Company pursuant to which such holders have agreed not to sell any shares of
Common Stock owned by them at the time of consummation of the Reorganization for
a period of 12 months following this offering, and to thereafter limit the sale
of such Common Stock to 25% of such shares upon expiration of such 12-month
period following this offering; up to an additional 25% of such shares upon
expiration of an 18-month period following this offering, and the remaining 50%
of such shares upon expiration of a 24-month period following this offering.
Further, each of the holders of the Convertible Notes have also entered into
agreements with the Company pursuant to which each holder has agreed not to sell
any portion of the Convertible Notes or any shares of the Common Stock issued or
issuable upon conversion thereof for a period of 24 months following the date
the Convertible Notes were issued to such holder (which Convertible Notes were
issued between September 30, 1996 and December 31, 1996). If GE Capital
purchases Common Stock in this offering, it is expected that GE Capital would
agree not to sell any shares of Common Stock owned by them for a period of 12
months following this offering. The Company has agreed with the Underwriters not
to waive the restrictive provisions of these agreements for 180 days after the
date of
    
 
                                       67
<PAGE>   69
 
this Prospectus without the prior written consent of Smith Barney Inc. Upon
expiration of these agreements, the registered shares of Common Stock will be
eligible for resale in the public market and the unregistered shares of Common
Stock, the Convertible Notes and the shares of Common Stock issued or issuable
upon conversion of the Convertible Notes will become eligible for sale in the
public market, subject to the provisions of Rule 144 of the Securities Act.
 
   
     In addition, the Company and its officers and directors and substantially
all other holders of Common Stock and securities convertible into or exercisable
or exchangeable for Common Stock have agreed that for a period of 180 days after
the date of this Prospectus they will not, without the prior written consent of
Smith Barney Inc., offer, sell, contract to sell or otherwise dispose of Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock except, in the case of the Company, in certain limited
circumstances.
    
 
   
     The Company anticipates that prior to the consummation of this offering,
the Company will have outstanding under its Plan options to purchase
approximately 1,681,000 shares of Common Stock, and at or shortly following
consummation of this offering the Company anticipates that it will issue options
to purchase up to 275,000 shares of Common Stock under the Plan. The Company
intends to register the shares of Common Stock issuable upon exercise of the
options granted under the Plan so that such shares will be eligible for resale
in the public market. The sale of the shares will be subject to the lock-up
provisions described above.
    
 
     In general, under Rule 144 as currently in effect, if one year has elapsed
since the later of the date of the acquisition of restricted shares of Common
Stock from the Company or any affiliate of the Company, the acquiror or
subsequent holder thereof may sell, within any three-month period, a number of
shares that does not exceed the greater of 1% of the then-outstanding shares of
Common Stock or the average weekly trading volume of the Common Stock on all
exchanges and/or reported through the automated quotation system of a registered
securities association during the four calendar weeks preceding the date on
which notice of the sale is filed with the Securities and Exchange Commission.
Sales under Rule 144 are also subject to certain manner of sale provisions,
notice requirements and the availability of current public information about the
Company. If two years have elapsed since the later of the date of acquisition of
restricted shares of Common Stock from the Company or any affiliate of the
Company and the acquiror or subsequent holder thereof is deemed not to have been
an affiliate of the Company at any time during the 90 days preceding a sale,
such person will be entitled to sell such shares under Rule 144(k) without
regard to the limitations described above.
 
     Prior to this offering there has been no market for the Common Stock, and
no prediction can be made as to the effect, if any, that the sale of shares or
the availability of shares for sale will have on the market price prevailing
from time to time. Nevertheless, sales of substantial amounts of the Common

     The Underwriters are obligated to take and pay for all shares of Common
Stock offered hereby (other than those covered by the over-allotment option
described below) if any such shares are taken.
 
   
     The Underwriters, for whom Smith Barney Inc., BancAmerica Robertson
Stephens, Cowen & Company and Piper Jaffray Inc. are acting as representatives
(the "Representatives"), propose initially to offer part of the shares of Common
Stock directly to the public at the public offering price set forth on the cover
page hereof and part to certain dealers at a price that represents a concession
not in excess of $          per share under the public offering price. The
Underwriters may allow, and such dealers may reallow, a concession not in excess
of $          per share to other Underwriters or to certain other dealers. After
the initial public offering, the public offering price and such concessions may
be changed by the Underwriters. The Representatives have informed the Company
that the Underwriters do not intend to confirm sales to accounts over which they
exercise discretionary authority.
    
 
     The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an aggregate of 750,000
additional shares of Common Stock at the public offering price set forth on the
cover page hereof less underwriting discounts and commissions. The Underwriters
may exercise such option to purchase additional shares solely for the purpose of
covering over-allotments, if any, incurred in connection with the sale of the
shares offered hereby. To the extent such option is exercised, each Underwriter
will become obligated, subject to certain conditions, to purchase approximately
the same percentage of such additional shares as the number set forth next to
such Underwriter's name in the preceding table bears to the total number of
shares in such table.
 
   
     The Underwriters have reserved $5.0 million of shares of the Common Stock
offered hereby to offer to GE Capital at the initial public offering price. The
Underwriters will not receive any underwriting discounts or commissions with
respect to any shares sold to GE Capital.
    
 
     The Company and the Underwriters have agreed to indemnify each other
against certain liabilities, including liabilities under the Securities Act.
 
     Each holder of Convertible Notes and each holder of shares of Common Stock
to be issued in the Reorganizations has agreed with the Company to certain
contractual restrictions on resales of such securities and, in the case of the
Convertible Notes, the underlying Common Stock. The Company has agreed with the
 
                                       69
<PAGE>   71
 
   
Underwriters not to waive the restrictive provisions of these agreements for 180
days after the date of this Prospectus without the prior written consent of
Smith Barney Inc. In addition, the Company and its officers and directors and
substantially all other holders of Common Stock and securities convertible into
or exercisable or exchangeable for Common Stock have agreed that for a period of
180 days after the date of this Prospectus they will not, without the prior
written consent of Smith Barney Inc., offer, sell, contract to sell or otherwise
dispose of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock except, in the case of the Company, in certain
limited circumstances. See "Shares Eligible for Future Sale."
    
 
     In connection with this offering and in accordance with applicable law and
industry practice, the Underwriters may over-allot or effect transactions which
stabilize, maintain or otherwise affect the market price of the Common Stock at
levels above those which might otherwise prevail in the open market, including
by entering stabilizing bids, effecting syndicate covering transactions or
imposing penalty bids. A stabilizing bid means the placing of any bid, or the
effecting of any purchase, for the purpose of pegging, fixing or maintaining the
price of a security. A syndicate covering transaction means the placing of any
bid on behalf of the underwriting syndicate or the effecting of any purchase to
reduce a short position created in connection with the offering. A penalty bid
means an arrangement that permits Smith Barney Inc., as managing underwriter, to
reclaim a selling concession from a syndicate member in connection with the
offering when shares of Common Stock originally sold by the syndicate member are
purchased in syndicate covering transactions. Such transactions may be effected
on the Nasdaq National Market, in the over-the-counter market, or otherwise. The
Underwriters are not required to engage in any of these activities. Any such
activities, if commenced, may be discontinued at any time.
 
     Cowen & Company, one of the Representatives, purchased $200,000 principal
amount of the Convertible Notes in December 1996 at a purchase price equal to
100% of the principal amount thereof. The Convertible Notes held by Cowen &
Company were purchased on the same terms as, are pari passu with, and provide
the same privileges as, all of the Convertible Notes sold by the Company.
 
   
     Prior to this offering, there has been no public market for the Common
Stock. Consequently, the initial public offering price for the Common Stock has
been determined by negotiations between the Company and the Representatives.
Among the factors considered in determining the initial public offering price
were the history of, and the prospects for, the Company's business and the
industry in which it competes, an assessment of the Company's management, its
past and present operations, the past and present earnings of the Company and
the trend of such earnings, the prospects for earnings of the Company, the
present state of the Company's development, the general condition of the
securities market at the time of this offering and the market prices of similar
securities of comparable companies at the time of this offering.
    
 
                                 LEGAL MATTERS
 
   
     The validity of the Common Stock offered hereby will be passed upon for the
Company by Brobeck, Phleger & Harrison LLP, Newport Beach, California and for
the Underwriters by Dewey Ballantine LLP, New York, New York. As of the date of
this Prospectus, certain members and investment partnerships of Brobeck, Phleger
& Harrison LLP beneficially own $67,500 in principal amount of the Convertible
Notes.

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

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
1. DESCRIPTION OF BUSINESS:
 
     American Physician Partners, Inc. -- A Development Stage Company (the
"Company"), a Delaware corporation, is a radiology practice management entity.
The Company is a development stage company which through December 31, 1996, had
no revenue or significant operations. During the period from inception (April
30, 1996) to December 31, 1996, the Company reported a net loss of approximately
$1.6 million primarily as a result of general and administrative expenses
incurred during its startup and organizational stage. The Company's operating
prospects are dependent upon a number of factors including the ability to
attract physicians to its business concept and integrate their operations,
competition from similar entities as the Company and overall trends in the
healthcare industry (including the effects of government regulation and
reimbursement trends).
 
2. SIGNIFICANT ACCOUNTING POLICIES:
 
  Basis of Presentation
 
     The financial statements have been prepared on the accrual basis of
accounting and include the accounts of the Company.
 
     The Company's financial statements have been prepared in anticipation of an
initial public offering of the Company's common stock (the "offering").
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with original
maturities of three months or less when purchased to be cash equivalents.
 
  Property and Equipment
 
     Property and equipment, consisting of furniture, fixtures, and equipment,
are stated at cost. Depreciation is calculated using the straight-line method
over the estimated useful lives of the assets (five years).
 
  Net Loss Per Share
 
     Net loss per share data has not been presented as historical information
does not reflect the distribution to the promoters (see Note 8) which will occur
in conjunction with the offering and will be paid with the proceeds thereof.
 
   
     In February 1997, the Financial Accounting Standards Board issued Statement
128, "Earnings Per Share" (FASB No. 128.) This Statement simplifies the
standards for computing earnings per share previously found in APB No. 15,
"Earnings Per Share," and applies to entities with publicly held common stock or
potential publicly held common stock. FASB No. 128 is effective for financial
statements for both interim and annual periods ending after December 31, 1997,
early application is not permitted.
    
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Basis of Presentation -- Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim period from January 1, 1997, to June 30, 1997, has been included
herein. The results of operations for the interim period is not necessarily
indicative of the results for the full year.
 
3. CONVERTIBLE NOTES PAYABLE:
 
     During 1996, the Company issued $3,500,000 in convertible notes (the
"Notes"). As of December 31, 1996, $40,000 and $357,000 of the Notes are held by
employees and shareholders, respectively. The interest rate on the Notes is 6%
and they mature on January 31, 1998. The Notes may, at the election of the
noteholders of at least 50% of the outstanding principal amount, be converted
into shares of common stock at a conversion price of $8 per share, subject to
certain limitations, as defined in the Note agreement. In addition, upon or
after the effective date of the offering, the Company may redeem the Notes at
par in whole or in part. The Company expects that the note holders will elect
conversion upon the Company's request for redemption.
 
     If the Notes remain outstanding at January 31, 1998, the interest rate
increases to the prime rate plus 2% per annum.
 
     The Company issued $400,000 in notes to stockholders during 1996. The
interest rate on these notes was the bank base lending rate. These notes were
paid in full prior to December 31, 1996.
 
4. COMMON STOCK AND STOCK OPTION PLAN:
 
  Common Stock
 
     During 1996, the Company's Board of Directors issued 2,000,000 shares of
common stock. No shares of stock were held by employees at December 31, 1996.
 
  Stock Option Plan
 
     During 1996, the Company's Board of Directors approved a Stock Option Plan
(the "Plan") under which 3,000,000 options to purchase shares of the Company's
common stock may be granted to key directors, employees and other health care
professionals associated with the Company, as defined by the Plan. Options
granted under the Plan may be either incentive stock options (ISO) or
nonqualified stock options (NQSO). The option price per share under the Plan may
not be less than 100% of the fair market value at the grant date for ISO and may
not be less than 85% of the fair market value at the grant date for NQSO.
Generally, options vest over a 5-year period.
 
     The Company accounts for its stock-based compensation arrangements under
the provisions of Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" (APB No. 25). In 1995, Financial Accounting Standards
Board Statement No. 123, "Accounting for Stock-Based Compensation" (FASB No.
123), was issued, whereby companies may elect to account for stock-based
compensation using a fair value based method or continue measuring compensation
expense using the intrinsic value method prescribed in APB No. 25. FASB No. 123
requires that companies electing to continue to use the intrinsic

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
value method make pro forma disclosure of net income and net income per share as
if the fair value based method of accounting had been applied.
 
     The Company used the minimum value method to estimate the fair value of
options. For purposes of the minimum value method, the Company used U.S.
Treasury strip rates for its risk-free interest rates, assumed no volatility or
future dividends, and assumed the expected life of the options through the
applicable expiration dates. The pro forma effects of adopting FASB No. 123's
fair value based method for the period ended December 31, 1996 were not
materially different from the corresponding APB No. 25 intrinsic value
methodology because the weighted average grant-date fair value of options
granted during the period was negligible. However, the effects of applying FASB
No. 123 during 1996 are not likely to be representative of the effects on pro
forma net income for future years because the vesting of options will cause
additional incremental expense to be recognized in future periods.
 
     As of December 31, 1996, 1,210,000 options were granted and 1,790,000
options were available to be granted under the Plan. The weighted average
exercise prices for total granted options and total exercisable options were
$.74 and $.20, respectively, at December 31, 1996. The following table
summarizes information for the significant option groups outstanding at December
31, 1996:
 
<TABLE>
<CAPTION>
EXERCISE     OPTIONS      REMAINING    EXERCISABLE
 PRICE     OUTSTANDING      LIFE         OPTIONS
- --------   -----------   -----------   -----------
                           (YEARS)
<C>        <C>           <C>           <C>
 $ .125     1,115,000        10            99,083
   8.00        95,000        10               917
</TABLE>
 
     Upon the effective date of the offering, the vesting period of 480,000
options will accelerate. Acceleration of the vesting period does not change the
measurement date pursuant to the provisions of APB 25 and accordingly no
compensation expense will be recognized.
 
5. INCOME TAXES:
 
     The Company has incurred losses since inception. At December 31, 1996, the
Company has a net operating loss carryforward for income tax purposes of
approximately $1,647,000 available to reduce future amounts of taxable income.
If not utilized to offset future taxable income, the net operating loss
carryforward will expire in 2011.
 
     The deferred tax benefit of approximately $600,000 generated during 1996
has been fully offset by a valuation allowance. The Company has recorded a full
valuation allowance against its deferred tax asset because of the Company's
current financial condition, its limited operating history, and its operating
losses recorded to date. If the Company does achieve profitability in the
future, the valuation allowance will be reduced by a credit to income.
 
6. DISCLOSURES ABOUT THE FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107, "Disclosures About
Fair Value of Instruments," requires disclosure about the fair value of
financial instruments. The carrying amounts and the estimated fair values for
these financial instruments as of December 31, 1996, were as follows:

8. SUBSEQUENT EVENTS:
 
     The Company plans to reorganize and complete an initial public offering. As
part of this transaction, all nonmonetary assets and certain monetary assets
(primarily accounts receivable, cash, and other monetary assets such as
inventory, deposits, prepaids and miscellaneous other receivables, but excluding
notes receivable from physicians) and liabilities, excluding those liabilities
payable to physicians such as accrued or defined physician compensation, and
certain other liabilities payable to physicians related to other benefit plans
of seven radiology practices (the "Founding Affiliated Practices") will be
exchanged for the Company's common stock and cash. Each of the stockholders of
the Founding Affiliated Practices is deemed to be a promoter of the offering.
The exchange will be accounted for at the historical cost basis with the stock
being valued at the historical cost of the net assets exchanged. The cash
payments to the owners of the Founding Affiliated Practices will be reflected as
dividends paid by the Company. Concurrent with these exchanges, the physicians
will create new medical professional corporations (PC's) which will enter into
40-year service agreements with the Company. Additionally, all physicians will
enter into employment and noncompete agreements with the new PC's.
 
     As of the closing date, the Company will agree to pay the owners of the
Founding Affiliated Practices amounts equal to their existing cash and net
accounts receivable, less certain accounts payable and accrued liabilities of
the Founding Affiliated Practices.
 
     The following summarized unaudited pro forma information assumes the
exchange between the Company and the Founding Affiliated Practices, but does not
give effect to the offering or the distribution to promoters. This pro forma

Company's management. Our responsibility is to express an opinion on these

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        DECEMBER 31, 1994, 1995 AND 1996
 
1. BUSINESS, ORGANIZATION AND BASIS OF PRESENTATION:
 
     Advanced Radiology, LLC (the "Company") is a Maryland limited liability
company organized to provide radiology and imaging healthcare services. Its
offices are located in the Baltimore, Maryland, metropolitan area. The Company
was organized in October 1994 and began providing healthcare services in January
1995.
 
     The consolidated financial statements include the accounts of the Company
and its seventy-three percent owned subsidiary, MRI at St. Joseph Medical
Center, LLC ("MRI"). All significant intercompany accounts and transactions have
been eliminated in consolidation.
 
   
     The Company was formed through the contribution of assets and medical
business of five existing radiology practices -- Drs. Copeland, Hyman, and
Shackman, P.A. ("Copeland"); Drs. Thomas, Wallop, Kim, and Lewis, P.A.
("Arundel"); Diagnostic Imaging Associates, P.A. (DIAPA); Drs. DeCarlo, Lyon,
Hearn, and Pazourek, P.A. ("DeCarlo"); and Carroll Imaging Associates, P.A.
("Carroll") (collectively, the "Practices"). Effective January 1, 1995, the
Practices contributed certain assets (primarily fixed assets and investments in
joint ventures) and the debt related to those assets in exchange for ownership
interests in the Company. The Company did not acquire the ownership interests of
the Practices; however, the Company became the sole provider of medical
services. The Practices remain in existence and continue to employ all
physician-owners. Distributions are made by the Company to the Practices, who
then pay all physician-owner salaries. Such distributions have been included as
operating expenses in the consolidated statements of income.
    
 
   
     The initial formation of the Company has been accounted for as a purchase
under APB No. 16. Based on the asset sizes of the individual contributed
radiology practices, Copeland was identified as the accounting acquirer, and
accordingly, all balances prior to January 1, 1995, represent the activities of
Copeland on a stand alone basis. The net assets contributed by Arundel, DIAPA,
DeCarlo, and Carroll were recorded at the estimated fair value of the assets
contributed and liabilities assumed. The excess purchase price (goodwill) was
determined based upon the fair value of the ownership interest received relative
to Copeland less the fair value of net assets contributed. Following are the
assets and liabilities, by practice.

     In addition, as part of the initial formation of the Company, all of the
assets and liabilities of Copeland, other than fixed assets, debt, and certain
miscellaneous assets, were maintained by Copeland and were not contributed to
the Company. Net assets in the amount of $6,471,600 (consisting primarily of
accounts receivable) were not contributed to the Company by Copeland. This
amount, less the $6,711,808 described above, has been reflected as a
contribution of $240,208 in the accompanying consolidated statements of owners'
equity.

     Each of the Practices received Class B membership interests in the Company.
Such Class B interests represent in excess of 99% of the Company's ownership.
The Class A members are approximately 50 physicians, each owning an .01%
interest. The Class B members appoint the Management Committee, which has the
authority to manage regular operations of the Company.
 
     In April 1996, Harbor Radiologists, P.A. ("Harbor") was admitted as a
14.30% Class B member of the Company. Its shareholders were also admitted as
Class A members. The estimated fair market values of assets and liabilities
contributed by Harbor in exchange for an interest in the Company are as follows:

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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Medical Service Revenues
 
     Medical service revenue are accounted for in the period in which the
services are provided. The revenue are reported at the estimated realizable
amounts from patients, third party payors and others. Provisions for estimated
third party payor adjustments are estimated and recorded in the period the
related services are provided. Any adjustment to the amounts is recorded in the
period in which the revised amount is determined. A significant portion of the
Company's medical service revenue are related to Medicare and other governmental
programs. Medicare and other governmental programs reimburse physicians based on
fee schedules which are determined by the related governmental agency.
Additionally, the Company participates in agreements with managed care
organizations to provide services at negotiated rates.
 
   
     All physician owners are employed by the Practices. Distributions are made
by the Company to the Practices, who then pay all physician owner salaries. Such
distributions have been included as an operating expense in the consolidated
statements of income.
    
 
  Costs of Affiliated Physician Services
 
   
     Costs of Affiliated Physician Services include all compensation to
non-owner physicians, as well as certain benefits, educational and travel costs
paid to non-owner physicians and physician owners.
    
 
  Income Taxes
 
   
     There is no provision for income taxes in the accompanying consolidated
financial statements. The members include their respective share of Company
profits and losses in their individual and corporate tax returns. In 1994,
Copeland was an S corporation, and accordingly all profits and losses were
reported by the individual physicians in their individual corporate returns.
    
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Basis of Presentation -- Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim periods from January 1, 1996, to June 30, 1996, and from January
1, 1997, to June 30, 1997, have been included herein. The results of operations
for the interim periods are not necessarily indicative of the results for the
full year.

3. INVESTMENTS IN AFFILIATED ENTITIES:
 
     In 1995, investments in affiliated entities consist of 50% interests in two

outstanding balances on two of the term loan note payables described above, are
limited to $20,000,000 in total. At December 31, 1996, the maximum amount of
funds available under the credit facility approximated $8,200,000. Advances are
collateralized by a first lien on all assets of the Company and the guarantees
of the five Class B members.
 
     In connection with the term and revolving credit facility to Mercantile,
the Company is required to maintain a liabilities to net worth ratio not
exceeding 1 to 1, and a minimum cash flow coverage ratio of at least 1.25 to 1.

     The Company performs radiology and imaging healthcare services under
managed care contracts entered into and administered by AMI (see Note 3), and
remits a management fee to AMI. Such management fees were not significant in
1995 and 1996. In addition, the Company pays certain expenses on behalf of AMI
and is periodically reimbursed. There are no significant amounts due from or to
AMI at December 31, 1995 and 1996.
 
   
     The Company leases seven of its office facilities from entities in which
certain of the Company's members have ownership interests. Rent expense relating
to such facilities was approximately $800,000 in 1995 and $796,000 in 1996.

9. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. The carrying amounts of accounts receivable, accounts payable and
accrued expenses approximate fair value due to the short maturity of these
instruments. The carrying amount of the Company's long-term debt also
approximates fair value.
 
10. MEMBERSHIP REDEMPTION OPTION:
 
     Under the terms of the Company's operating agreement, at any time on or
after October 17, 1999, the Company has the option to redeem the membership
interests of all of the Class B members (which are the corporate members of the
Company) at a price equal to the then positive capital account balances of such
members, or, if such balances are zero or negative, for a price of $10.
Twenty-five percent of the redemption price is to be paid no later than six
months after the exercise of the option with the remainder generally being paid
in three annual installments, including interest.
 
11. CONTINGENCIES:
 
     The Company is a defendant in certain claims arising from alleged acts of
malpractice. Legal counsel for the Company is of the opinion that such claims
are adequately covered by malpractice insurance.
 
     The Company is a defendant in a lawsuit brought by two former employees of
a Class B member alleging employment discrimination. Total damages claimed are
$80 million. The case has been compelled to binding arbitration; however, no
Scheduling Order has been issued, and no substantive discovery has taken place.
In the opinion of management, the ultimate disposition of this case will not
have a material adverse effect on the Company's financial condition or results
of operations.

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

                          INDEPENDENT AUDITORS' REPORT
 
To the Shareholders of
The Ide Group, P.C.:
 
     We have audited the accompanying combined balance sheets of The Ide Group,
P.C. (a New York professional corporation) and Ide Diagnostic Imaging Associates
(a New York general partnership) as of June 30, 1997, 1996 and 1995, and the
related combined statements of income, changes in stockholders' equity and
partners' capital, and cash flows for the three years then ended. These
financial statements are the responsibility of the Companies' management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free from
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of The Ide Group, P.C.
and Ide Diagnostic Imaging Associates as of June 30, 1997, 1996, and 1995, and
the results of their operations and their cash flows for the years then ended in
conformity with generally accepted accounting principles.

                          JUNE 30, 1997, 1996 AND 1995
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Presentation and Principles of Combination
 
     The accompanying combined financial statements present the combined
financial position, results of operations, and cash flows of The Ide Group, P.C.
("Ide"), a New York professional corporation, and Ide Diagnostic Imaging
Associates ("IDIA"), a New York general partnership. Ide was formed to practice
medicine specializing in radiology and radiation oncology in the Rochester, New
York region. IDIA provided magnetic resonance imaging services in the Rochester,
New York region. Effective January 1, 1996, substantially all of the operations
of IDIA were assumed by Ide.
 
     Ide and IDIA are affiliated through common ownership. All material
intercompany balances and transactions are eliminated in combination.
 
  Basis of Accounting
 
     The accompanying financial statements are prepared using the accrual basis
of accounting.
 
  Use of estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and reported amounts of revenue and expenses
during the reporting periods. Actual results could differ from these estimates.
 
  Revenue Recognition
 
     Revenue is recognized when the related service is performed. Revenue is
recorded net of allowances for contractual adjustments and estimated
uncollectible accounts.
 
  Supplies on Hand
 
     Supplies on hand are stated at the lower of cost, determined on the
first-in, first-out basis, or market.
 
  Property and Equipment
 
     Depreciation and amortization of property and equipment are computed using
methods and lives prescribed under the Internal Revenue Code, which are as
follows:

- ---------------
 
(a) During fiscal 1996, Ide refinanced its term loan agreement with M&T Bank
    ("The Bank"). The term loan agreement requires 60 equal monthly principal
    payments of $31,667 through January 2001 plus interest. Interest on the term
    loan is fixed at 7.74%. The term loan is secured by substantially all of
    Ide's assets. Ide has received a commitment from the Bank to allow
    borrowings up to a maximum of $3,000,000.
 
(b) The term loan agreement requires 60 equal monthly installments of $6,674
    including interest through June 2002. Interest on the term loan is fixed at
    8.54%. The term loan is secured by substantially all of Ide's assets.
 
(c) Ide refinanced this term loan agreement in fiscal 1996.
 
     As part of the financial covenants contained in Ide's agreements with M&T
     Bank, Ide must generate no less than zero taxable income as reflected in
     Ide's federal tax return and tangible net worth is not to decline by more
     than 20% during any fiscal year. At June 30, 1997, Ide was in default of
     both of these covenants. Waivers of these defaults have been obtained from
     the bank.
 
     The aggregate annual maturities of long-term debt are as follows:

3. LINES OF CREDIT:
 
     Ide has a line of credit facility with M&T Bank under which Ide may borrow
up to $1,300,000 at the prime rate (8.5% at June 30, 1997). There were no
borrowings outstanding under this line at June 30, 1997 and 1996. The line of
credit agreement requires that there be no outstanding borrowings under the line
for at least thirty consecutive days each year.
 
                                      F-31
<PAGE>   104
 
                              THE IDE GROUP, P.C.
 
                       IDE DIAGNOSTIC IMAGING ASSOCIATES
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Ide previously had an agreement with Chase Manhattan Bank, N.A. which
permitted Ide to borrow up to $600,000 through February 28, 1996. Borrowings
under the agreement were $200,000 at June 30, 1995. The note was repaid in full
and terminated in February 1996.
 
4. LIFE INSURANCE LOANS PAYABLE:
 
     Ide's life insurance loans payable are secured by the cash surrender value
of the related policies. These policies bear interest at rates which range from
a fixed rate of five percent to rates which float with the prime rate. It is
Ide's intention to not repay these loans during the next year. Therefore, the
loans are reflected as a long-term liability in the accompanying balance sheets.
 
5. INCOME TAXES:
 
     Ide follows the provisions of Statement of Financial Accounting Standards
Number 109, "Accounting for Income Taxes."
 
     Deferred taxes are recognized for temporary differences between the basis
of assets and liabilities for financial statement and income tax purposes. The
differences result from the use of the cash basis of accounting for income tax
purposes and the use of the accrual basis of accounting for financial statement
purposes, and consist primarily of accounts receivable, accounts payable,
accrued liabilities and net operating loss carryforwards. It is Ide's intention
in future years to pay compensation to employees in amounts sufficient to reduce
taxable income to zero each year.
 
     For federal tax return purposes, Ide has approximately $500,000 of net
operating loss carryforwards as of June 30, 1997, which expire in the years 2006
through 2012.
 
     The results of the Partnerships' operations are reported in the individual
federal and state income tax returns of the partners. The Partnership files
informational returns and, therefore, no provision for income taxes is recorded.
 
6. REFUNDABLE BONDS:
 
     Refundable bonds consist of deposits required for each Ide physician by
Ide's medical malpractice mutual insurance carrier. The bonds are refundable
from the free and divisible surplus of the insurance company upon cessation of
medical practice of the Ide physician. The bonds earn interest at the rate of
6%.
 
7. EMPLOYEE BENEFIT PLANS:
 
     Ide maintains a discretionary qualified defined contribution 401(k) and
profit sharing plan ("the Plan"), covering substantially all employees of Ide
and IDIA who have attained the age of 21 and who have met certain minimum
eligibility requirements. The plan is subject to provisions of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"). The plan also
provides that participants will be able to contribute up to 15% of their
compensation not to exceed $9,500. Ide contributes an amount equal to 25% of an
employee elective deferrals up to 4% of each employee's compensation.
 
     In addition, Ide maintains a qualified discretionary supplemental profit
sharing plan which is subject to provisions of ERISA. The profit sharing expense
under these plans was $490,769, $539,737 and $518,107 for the years ended June
30, 1997, 1996 and 1995, respectively.

8. COMMITMENTS AND CONTINGENCIES:
 
  Deferred Compensation Agreements
 
     Each Ide shareholder physician's employment contract contains a deferred
compensation agreement. Under the terms of these agreements, these individuals
will receive payments at retirement or death for past services performed. At
June 30, 1997, 1996 and 1995 the vested amount of deferred compensation balances
total approximately $8,966,681, $9,015,593, and $7,329,000, respectively. These
balances will be paid out over time at indeterminable future dates and in
indeterminable future amounts. As such, the amount of liability that would be
recorded in the balance sheet is not reasonably estimable.
 
  Leases
 
     Ide occupies certain offices under lease agreements expiring at various
dates through December, 2000. The minimum rental commitment under all leases in
effect at June 30, 1997 are as follows:

     The Partnership leases office space under leases expiring through 1998. The
Partnership is fully reimbursed for its office space rental expense under the
terms of its agreement with MICA (see Note 12).
 
9. RELATED PARTIES:
 
     On January 1, 1996, Ide purchased the property and equipment of a related
entity, IDIA.
 
     Ide has an agreement with an affiliated company whereby the affiliate
performs billing and collection functions for services rendered by Ide. Ide pays
the affiliate a fee based on the amount of billings collected. Payments to this
affiliate were $1,348,805, $1,547,143, and $1,324,882 in fiscal 1997, 1996 and
1995, respectively.
 
10. CREDIT RISK CONCENTRATIONS:
 
     Ide and IDIA maintain bank account balances which, at times, exceeded the
federally insured limit during the years ended June 30, 1997, 1996 and 1995. The
Companies have not experienced losses related to these deposits and management
does not believe that the Companies are exposed to any significant credit risk
with respect to these accounts.
 
     At June 30, 1997, Ide has approximately $1,465,416 of accounts receivable
due from Health Maintenance Organizations ("HMOs") which is subject to
retrospective adjustment. This amount represents withholdings by the HMOs to be
used against any operating losses incurred by the HMO. In fiscal 1996, Ide
received 80% of funds withheld under its contract with one HMO relating to
calendar 1995. Other than fiscal 1996, Ide has historically collected the full
amount of withheld funds each year.
 
     Substantially all of the Companies' revenue is derived from services
performed in the greater Rochester, New York metropolitan area.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Substantially all of the Companies' revenue is derived from providing
medical services to patients covered under contracts with Blue Cross/Blue Shield
of Greater Rochester or affiliates, Blue Choice, Preferred Care, Medicare, or
Medicaid. Changes in the reimbursement rates Ide receives under these contracts
could have a material effect on Ide's financial position and operations.
 
     Subsequent to June 30, 1996, Ide's management became aware of the intention
of the Rochester Community Individual Practice Association and the Rochester
Individual Practice Association, with whom Ide is a participating provider, to
adopt Resource-Based Relative Value Scale ("RBRVS") fee schedule methodologies.
These fee schedules will be implemented effective October 1, 1997. These
Individual Practice Associations ("IPA's") contract with Blue Choice and
Preferred Care, respectively. Approximately 60% of Ide's revenue is derived from
services provided to patients of Blue Choice and Preferred Care. The IPA's have
proposed community-wide budgets for imaging services based upon 1996
community-wide reimbursement levels. These budgets may reflect reductions in
community-wide imaging reimbursement of 12% in 1998 and 26% in 1999 and
thereafter.
 
11. SUPPLEMENTARY CASH FLOW DISCLOSURES:
 
     Ide considers all highly liquid instruments purchased with an original
maturity of three months or less to be cash equivalents.
 
     Cash payments for income taxes and interest are as follows for the years
ended June 30:

12. EXCLUSIVE SUPPLY AGREEMENT:
 
     On January 1, 1996, Ide assumed the obligations of an agreement between
IDIA and MICA Imaging and Medical Imaging Centers of America, Inc. ("MICA") in
which IDIA agreed to sell to MICA its magnetic resonance imaging ("MRI")
equipment and not to compete with MICA for the provision of MRI services in the
City of Rochester ("City") and within a twenty-five mile radius of the City.
This covenant not to compete also applies to all shareholders of Ide for the
duration of their participation as shareholders and for two years thereafter.
 
     In accordance with the agreement, Ide has the right of first refusal for
the thirty year term of the agreement to provide professional radiology services
at facilities located in specified states in the Northeast except under certain
circumstances as outlined in the agreement.
 
     MICA has the right of first refusal to provide MRI equipment, cryogens
and/or maintenance at any location in specific states in the Northeast where Ide
obtains the right to provide MRI equipment, cryogens and/or maintenance or where
Ide owns, leases or subleases office space for the purposes of providing MRI

13. ACQUISITION AGREEMENT:
 
     During fiscal 1997, the Company entered into an acquisition agreement with
American Physician Partners, Inc. ("APPI") under which APPI will acquire all of
the non-medical assets of Ide through a merger transaction.
 
     The non-medical assets consist of cash, imaging equipment, accounts
receivable, supplies on hand and other assets. These non-medical assets will be
separated from the medical assets through a reorganization of Ide to be
completed before the transaction with APPI. This reorganization will result in
the creation of a new entity ("New Ide") to provide regulated medical services.
APPI will assume certain liabilities of Ide pursuant to the agreement.
 
     Completion of the transaction is subject to certain conditions, including
the execution of a forty-year service agreement, stockholder approval by both
parties and successful completion of an initial public offering by APPI. Under
the terms of the service agreement, APPI will provide practice management,
administration and other services to New Ide for a negotiated service fee. All
non-professional employees shall become employees of APPI. In addition, APPI
will assume responsibility for all maintenance, repairs, improvements, lease and
other general operating expenses.
 
   
     The President of the Company is also a Shareholder of APPI.

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

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

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

     The Company also collects the receivables of the joint ventures, and then
periodically remits the collections to them. In addition, the Company pays
certain expenses on behalf of the joint ventures, and is periodically reimbursed
by them. At December 31, 1996, there were no significant balances due from (to)
the joint ventures.
 
10. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. Accordingly, the carrying amounts of accounts receivable, accounts
payable and accrued expenses approximate fair value due to the short maturity of
these instruments. The carrying amount of the Company's long-term debt and
capital lease obligations also approximates fair value.
 
11. CONTINGENCIES:
 
     The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the
Company's financial position or results of operations.
 
12. SUBSEQUENT EVENTS:
 
     On September 24, 1996, the Company entered into a letter of intent with
American Physician Partners, Inc. (APPI) under which APPI will acquire certain
assets and liabilities of the Company in exchange for common stock and cash.
Completion of the transaction is subject to certain conditions, including the
execution of a forty-year service agreement, stockholder approval by both
parties and successful completion of an initial public offering by APPI. Under
the terms of the service agreement, APPI will provide practice management,
administration and other services to the physicians for a negotiated service
fee. All nonprofessional employees shall become employees of APPI. In addition,
APPI will assume responsibility for all maintenance, repairs, improvements,
lease and other general operating expenses.

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

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

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Costs of Affiliated Physician Services
 
     Costs of Affiliated Physician Services include physician compensation and
benefits paid or payable to owner and non-owner physicians during the period.
 
  Income Taxes
 
     Pacific accounts for income taxes under the liability method which states
that deferred income taxes are determined based on the estimated future tax
effects of differences between the financial reporting and income tax basis of
assets and liabilities given the provisions of enacted tax laws. Deferred income
tax provisions are based on the changes to the asset or liability from period to
period. TMI is an S-corporation and LMI is a general partnership, and
accordingly, there is no provision for income taxes related to these entities.
The individual owners include their respective share of profits and losses in
their tax returns.
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the combined
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Basis of Presentation -- Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim periods from January 1, 1996, to June 30, 1996, and from January
1, 1997, to June 30, 1997, have been included herein. The results of operations
for the interim periods are not necessarily indicative of the results for the
full year.

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

8. RELATED-PARTY TRANSACTIONS:
 
     The Company has a non-interest bearing note receivable from an employee.

respectively. The note has no stated maturity date.
 
     The Company has a note receivable from a physician which bears interest at
8.5% and matures in August, 1995. Amounts outstanding at December 31, 1995 and
1996 were $38,936 and $36,173, respectively.

     At December 31, 1996, the Company had a $10,000 note receivable from a
physician which bears interest at 8.25% and matures in 1997. In addition, in
1996, the Company made non-interest bearing advances totaling $70,287 to certain
physicians. These advances are to be repaid in 1997.
 
     The Company has an ownership interest in a real estate partnership. Rent

9. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. Accordingly, the carrying amounts of accounts receivable, accounts
payable and accrued expenses approximate fair value due to the short maturity of
these instruments. The carrying amount of the Company's long-term debt also
approximates fair value.
 
10. CONTINGENCIES:
 
     The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the
Company's financial position or results of operation.
 
11. SUBSEQUENT EVENTS:
 
     On February 26, 1997, the Company entered into a letter of intent with
American Physician Partners, Inc. (APPI) under which APPI will acquire certain
assets and liabilities of the Company in exchange for common stock and cash.
Completion of the transaction is subject to certain conditions, including the
execution of a forty-year service agreement, stockholder approval by both
parties and successful completion of an initial public offering by APPI. Under
the terms of the service agreement, APPI will provide practice management,
administration and other services to the physicians for a negotiated service
fee. All nonprofessional employees shall become employees of APPI. In addition,
APPI will assume responsibility for all maintenance, repairs, improvements,
lease and other general operating expenses.
 
     Effective January 1, 1997, the Company and Valley Radiology Group, a group
of radiologists in San Jose, California, formed a management services
organization to manage their operations.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
1. BUSINESS, ORGANIZATION AND BASIS OF PRESENTATION:
 
     Radiology and Nuclear Medicine, a Professional Association (the "Company"),
is a professional corporation organized under the laws of the State of Kansas to
provide diagnostic radiology medical imaging and radiation oncology services.
Its offices are located in Topeka, Kansas and the surrounding area.
 
     The accompanying financial statements have been prepared on the accrual
basis of accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with maturities of
three months or less when purchased to be cash equivalents.
 
  Accounts Receivable
 
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payors for medical services
provided by physicians. Such amounts are reduced by an allowance for contractual
adjustments and other uncollectible amounts.
 
  Property and Equipment
 
     Property and equipment are recorded at cost. Depreciation on furniture,
fixtures and equipment is computed using straight-line methods over the
estimated useful lives of the assets. Leasehold improvements are amortized on
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Investments in Affiliated Entities
 
     The Company has investments in two partnerships, Magnetic Resonance Imaging
Center of Kansas ("MRI") and Medical Building West Associates, LP ("MBW") which
are accounted for using the equity method and the cost method, respectively (see
Note 3).
 
  Other Noncurrent Assets
 
     Other noncurrent assets consist of deposits with insurance companies and a
note receivable.
 
  Medical Service Revenues
 
     Medical service revenue are accounted for in the period in which the
services are provided. Revenues are reported at the estimated realizable amounts
from patients, third party payors and others. Provisions for estimated third
party payor adjustments are estimated and recorded in the period the related
services are provided. Any adjustment to the amounts is recorded in the period
in which the revised amount is determined. A significant portion of the
Company's medical service revenue are related to Medicare and other governmental
programs. Medicare and other governmental programs reimburse physicians based on
fee schedules which are determined by the related governmental agency.
Additionally, the Company participates in agreements with managed care
organizations to provide services at negotiated rates.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Income Taxes
 
     The Company accounts for income taxes under the liability method which
states that deferred income taxes are to be determined based on the estimated
future tax effects of differences between the financial reporting and income tax
bases of assets and liabilities given the provisions of enacted tax laws.
Deferred income tax provisions are based on the changes to the asset or
liability from period to period.
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Basis of Presentation - Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim periods from January 1, 1996, to June 30, 1996, and from January
1, 1997, to June 30, 1997, have been included herein. The results of operations
for the interim periods are not necessarily indicative of the results for the
full year.
 
3. INVESTMENTS:
 
     Investments in affiliated entities primarily consist of a 22% interest in
MRI and a 15% interest in MBW. The purpose of MRI is to own and operate real and
personal property. The purpose of MBW is to acquire/own land for the production
of income. The initial amount contributed to MBW was $1,000,000.

maintenance of its radiology and imaging equipment. The fees paid are expected
to approximate $57,000 per year.
 
9. EMPLOYEE BENEFIT PLAN:
 
     The Company sponsors a defined contribution pension plan for employees of
the Company who have completed one year of service, with a minimum of 1,000
hours worked. The plan provides for employer contributions of 10% of
compensation up to a maximum eligible compensation of $150,000. The Company's
contribution for 1995 and 1996 was approximately $472,000 and $477,000,
respectively.

     The Company also sponsors a 401(k) plan for employees of the Company who
have completed one year of service, with a minimum 1,000 hours worked. The plan
provides for employer matching contributions of one-half of employee
contributions, up to 2% of the employee's salary. The plan also allows for
employer discretionary contributions. The Company's contributions for 1995 and
1996 were approximately $189,000 and $185,000, respectively.
 
10. RELATED-PARTY TRANSACTIONS:
 
     As indicated in Note 3, the Company has a 15% partnership interest in MBW
from which the Company leases its office space. Rent expense relating to such
facilities was approximately $150,000 in 1995 and 1996.
 
11. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. Accordingly, the carrying amounts of accounts receivable, accounts
payable, accrued expenses, short-term borrowings and long-term debt approximate
fair value due to the short maturity of these instruments.
 
12. CONTINGENCIES:
 
  Litigation
 
     The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the
Company's financial position or results of operations.
 
  Insurance
 
     The Company is self-insured for employee health benefits. Stop-loss
insurance coverage has been purchased to cover claims exceeding certain
retention limits. At December 31, 1996, the Company's maximum exposure for
health insurance claims was $20,000 per family with an aggregate maximum limit
of 125% of expected claims, as determined by the insurance company
(approximately $379,000 in 1996.) An estimate of the amount due and payable on
existing claims for which the Company is liable is included in accrued expenses.
 
13. SUBSEQUENT EVENTS:
 
     On January 20, 1997, the Company entered into a letter of intent with
American Physician Partners, Inc. (APPI) under which APPI will acquire certain
assets and liabilities of the Company in exchange for common stock and cash.
Completion of the transaction is subject to certain conditions, including the
execution of a forty-year service agreement, stockholder approval by both
parties and successful completion of an initial public offering by APPI. Under
the terms of the service agreement, APPI will provide practice management,
administration and other services to the physicians for a negotiated service
fee. All nonprofessional employees shall become employees of APPI. In addition,
APPI will assume responsibility for all maintenance, repairs, improvements,
lease and other general operating expenses.

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

                       SEPTEMBER 30, 1994, 1995, AND 1996
 
1. BUSINESS, ORGANIZATION AND BASIS OF PRESENTATION:
 
     The accompanying financial statements combine the accounts of nine entities
under common ownership: Mid Rockland Imaging Associates, P.C. ("MRI"), Rockland
Radiological Group, P.C. ("RRG"), Nyack Magnetic Resonance Imaging, P.C.
("NMR"), Central Imaging Associates, P.C., Advanced Imaging of Bergen, P.A.,
Pelham Imaging Associates, P.C., Women's Imaging Consultants, P.C., Montvale
Regional Imaging of Bergen, P.A., and Advanced Imaging of Orange County, P.C.
(collectively the "Company"), all of which are located in the states of New York
and New Jersey and specialize in the practice of radiological medicine. All
intercompany items and transactions have been eliminated.
 
     The accompanying financial statements have been prepared on the accrual
basis of accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Cash and cash equivalents
 
     The Company considers all highly liquid investments with maturities of
three months or less when purchased to be cash equivalents.
 
  Accounts Receivable
 
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payors for medical services
provided by physicians. Such amounts are reduced by an allowance for contractual
adjustments and other uncollectible amounts.
 
  Property and Equipment
 
     Property and equipment is recorded at cost. Depreciation on furniture,
fixtures and equipment is computed using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are amortized on
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Deferred Compensation
 
     Under the terms of the physician employment agreements, physicians who have
completed a minimum of eight years of service are entitled to a payment of up to
one hundred percent of their final compensation upon retirement or when they
cease to be employees of the Company. The percentage of salary received by the
physician varies based upon the number of years of service. These payments are
made in 36 equal monthly payments beginning upon attainment of age 70 or the
date when the physician leaves the Company. The estimated present value of these
obligations is being accrued ratably during the eight year service period.
 
  Medical Service Revenue
 
     Medical service revenues are accounted for in the period in which the
services are provided. The revenues are reported at the estimated realizable
amounts from patients, third party payors and others. Provisions for estimated
third party payor adjustments are estimated and recorded in the period the
related services are provided. Any adjustment to the amounts is recorded in the
period in which the revised amount is determined. A significant portion of the
Company's medical service revenues are related to Medicare and other
governmental programs. Medicare and other governmental programs reimburse
physicians based on fee

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
schedules which are determined by the related governmental agency. Additionally,
the Company participates in agreements with managed care organizations to
provide services at negotiated rates.
 
  Costs of Affiliated Physician Services
 
     Costs of Affiliated Physician Services include physician compensation and
benefits paid or payable to owner and non-owner physicians during the period.
 
  Income Taxes
 
     MRI and RRG account for income taxes under the liability method which
states that deferred income taxes are to be determined based on the estimated
future tax effects of differences between the financial reporting and income tax
basis of assets and liabilities given the provisions of enacted tax laws.
Deferred income tax provisions are based on the changes to the asset or
liability from period to period. The remaining companies included in the
accompanying combined financial statements are S corporations, and accordingly,
there is no provision for income taxes related to these entities. The individual
owners include their respective share of Company profits and losses in their tax
returns.
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the combined
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
  Basis of Presentation -- Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim periods from October 1, 1995, to June 30, 1996, and from October
1, 1996, to June 30, 1997, have been included herein. The results of operations
for the interim periods are not necessarily indicative of the results for the
full year.

8. EMPLOYEE BENEFIT PLAN:
 
     The Company sponsors a profit sharing and 401(k) plan for employees of the
Company, who have completed one year of service and are at least age 21. The
plan provides for employer profit sharing contributions, depending upon the
level of the employee. The plan also provides for employees matching
contributions of 100% of employee contributions, up to 3% of the employee's
salary. The Company's contributions for 1994, 1995, and 1996 were $253,656,
$363,809, and, $404,047 respectively.
 
9. RELATED-PARTY TRANSACTIONS:

     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. The carrying amounts of accounts receivable, accounts payable and
accrued expenses approximate fair value due to the short maturity of these
instruments. The carrying amount of the Company's long-term debt and capital
leases also approximates fair value.
 
11. CONTINGENCIES:
 
     The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the
Company's financial position or results of operations.
 
12. SUBSEQUENT EVENTS:
 
     On November 15, 1996, the Company entered into a letter of intent with
American Physician Partners, Inc. (APPI) under which APPI will acquire certain
assets and liabilities of the Company in exchange for common stock and cash.
Completion of the transaction is subject to certain conditions, including the
execution of a forty-year service agreement, stockholder approval by both
parties and successful completion of an initial public offering by APPI. Under
the terms of the service agreement, APPI will provide practice management,
administration and other services to the physicians for a negotiated service
fee. All nonprofessional employees shall become employees of APPI. In addition,
APPI will assume responsibility for all maintenance, repairs, improvements,
lease and other general operating expenses.
 
     In April, 1997, the Company entered into an agreement to purchase certain
assets of Kingston Diagnostic Radiology, P.C. for $2,000,000 in cash and certain
assumed liabilities of approximately $1,850,000. Completion of the transaction
is subject to execution of a five-year service contract.
 
     On March 11, 1997, Wallkill Radiology Associates, P.C. ("Wallkill")
contributed all of its assets to the Company. In exchange, the sole stockholder
of Wallkill was made an equal partner of the Company. At December 31, 1996,
Wallkill had total assets of approximately $480,000. For the year ended December
31, 1996, Wallkill had total revenues of approximately $1,480,000.

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

                           DECEMBER 31, 1995 AND 1996
1. BUSINESS, ORGANIZATION AND BASIS OF PRESENTATION:
 
     The accompanying financial statements combine the accounts of three
entities under common ownership: Valley Radiologists Medical Group, Inc.
("Valley"), a California corporation; LXL, Ltd. ("LXL"), a California general
partnership; and LXL Building Partnership ("LXLB"), a California general
partnership (collectively the "Company"), all of which are located in northern
California and specialize in the practice of radiological medicine and the
ownership and operation of diagnostic imaging equipment. All intercompany
transactions have been eliminated.
 
     The accompanying financial statements have been prepared on the accrual
basis of accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Cash and Cash equivalents
 
     The Company considers all highly liquid investments with maturities of
three months or less when purchased to be cash equivalents.
 
  Accounts Receivable
 
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payors for medical services
provided by physicians. Such amounts are reduced by an allowance for contractual
adjustments and other uncollectible amounts.
 
  Property and Equipment
 
     Property and equipment are recorded at cost. Depreciation on furniture,
fixtures and equipment is computed using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are amortized on
the straight-line method over the shorter of the noncancelable lease term or
estimated useful life of the asset. However, if the noncancelable lease term
expires in the near future and if the lease contains a renewal option of which
management is reasonably assured of exercising, the amortization period is the
shorter of the lease term including the renewal option period or the estimated
useful life.
 
  Investments in Affiliated Entities
 
     Investments in affiliated entities are accounted for using the equity
method.
 
  Other Assets
 
     Other assets are comprised of organization costs, noncompete agreements and
security deposits. Organization costs are being amortized on a straight-line
basis over a five-year period. Noncompete agreements are amortized on a
straight-line basis over the life of the agreements.
 
  Medical Service Revenues
 
     Medical service revenues are accounted for in the period in which the
services are provided. The revenues are reported at the estimated realizable
amounts from patients, third party payors and others. Provisions for estimated
third party payor adjustments are estimated and recorded in the period in which
the related services are provided. Any adjustment to the amounts is recorded in
the period in which the revised amount is determined. A significant portion of
the Company's medical service revenues are related to Medicare and other
governmental programs. Medicare and other governmental programs reimburse
physicians based on fee schedules which are determined by the related
governmental agency. Additionally, the Company participates in agreements with
managed care organizations to provide services at negotiated rates.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                           DECEMBER 31, 1995 AND 1996
 
  Costs of Affiliated Physician Services
 
     Costs of Affiliated Physician Services include physician compensation and
benefits paid or payable to owner and non-owner physicians during the period.
 
  Income Taxes
 
     Valley accounts for income taxes under the liability method which states
that deferred income taxes are determined based on the estimated future tax
effects of differences between the financial reporting and income tax basis of
assets and liabilities given the provisions of enacted tax laws. Deferred income
tax provisions are based on the changes to the asset or liability from period to
period. LXL and LXLB are partnerships, and accordingly, there is no provision
for income taxes related to these entities. The individual owners include their
respective share of profits and losses in their tax returns.
 
  Concentration of Credit Risk
 
     The Company extends credit to patients covered by programs such as Medicare
and Medicaid and private insurers. The Company manages credit risk with the
various public and private insurance providers, as appropriate. Allowances for
bad debts have been made for potential losses when appropriate.
 
  Use of Estimates
 
     The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the combined
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
  Basis of Presentation - Interim Financial Statements
 
     The interim financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of Accounting Principles Board
("APB") Opinion No. 28, "Interim Financial Reporting." Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to APB Opinion No. 28; nevertheless, management of the Company
believes that the disclosures herein are adequate to prevent the information
presented from being misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position of the Company with respect to the results of its operations
for the interim periods from January 1, 1996, to June 30, 1996, and from January
1, 1997, to June 30, 1997, have been included herein. The results of operations
for the interim periods are not necessarily indicative of the results for the
full year.
 
3. NOTES RECEIVABLE:
 
     Notes receivable primarily consist of a $400,000 note receivable from a
third party, due July 18, 1999 with monthly interest only payments until that
date. The note bears interest of 8.0%.
 
4. INVESTMENTS IN AFFILIATED ENTITIES:
 
     Investments in affiliated entities primarily consist of 40% interests in
two partnerships (Santa Clara Valley MRI ("Santa Clara") and Sunnyvale MRI
("Sunnyvale"), each of which perform radiology and

11. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     Statement of Financial Accounting Standards No. 107 requires all entities
to disclose the fair value of certain financial instruments in their financial
statements. The carrying amounts of accounts receivable, accounts payable and
accrued expenses approximate fair value due to the short maturity of these
instruments. The carrying amount of the Company's long-term debt also
approximates fair value.
 
12. CONTINGENCIES:
 
     The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the
Company's financial position or results of operations.
 
13. SUBSEQUENT EVENTS:
 
     On March 6, 1997, the Company entered into a letter of intent with American
Physician Partners, Inc. (APPI) under which APPI will acquire certain assets and
liabilities of the Company in exchange for common stock and cash. Completion of
the transaction is subject to certain conditions, including the execution of a
forty-year service agreement, stockholder approval by both parties and
successful completion of an initial public offering by APPI. Under the terms of
the service agreement, APPI will provide practice management, administration and
other services to the physicians for a negotiated service fee. All
nonprofessional employees shall become employees of APPI. In addition, APPI will
assume responsibility for all maintenance, repairs, improvements, lease and
other general operating expenses.
 
     In 1997, the Company refinanced its $900,000 line of credit with a term
note. The term note provides for borrowings of $925,000 due February 2002.
 
     Effective January 1, 1997, the Company and Pacific Imaging Consultants, a
group of radiologists in Oakland, California, formed a management services
organization to manage their operations.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Company's Amended Bylaws provide that the Company shall, to the fullest
extent permitted by Section 145 of the DGCL, as amended from time to time,
indemnify all persons whom it may indemnify pursuant thereto.
 
     Section 145 of the DGCL permits a corporation, under specified
circumstances, to indemnify its directors, officers, employees or agents against
expenses (including attorney's fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by them in connection with any
action, suit or proceeding brought by third parties by reason of the fact that
they were or are directors, officers, employees or agents of the corporation, if
such directors, officers, employees or agents acted in good faith and in a
manner they reasonably believed to be in or not opposed to the best interests of
the corporation and, with respect to any criminal action or proceeding, had no
reason to believe their conduct was unlawful. In a derivative action, i.e., one
by or in the right of the corporation, indemnification may be made only for
expenses actually and reasonably incurred by directors, officers, employees or
agents in connection with the defense or settlement of an action or suit, and
only with respect to a matter as to which they shall have acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification shall be made if
such person shall have been adjudged liable to the corporation, unless and only
to the extent that the court in which the action or suit was brought shall
determine upon application that the defendant directors, officers, employees or
agents are fairly and reasonably entitled to indemnity for such expenses despite
such adjudication of liability.
 
     Article VI of the Company's Restated Certificate of Incorporation, as
amended, provides that the Company's directors will not be personally liable to
the Company or its stockholders for monetary damages resulting from breaches of

     Act, the information omitted from the form of prospectus filed as part of a
     registration statement in reliance upon Rule 430A and contained in the form
     of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For purposes of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registration pursuant to the provisions described in Item 14 hereof, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                           INDEMNIFICATION AGREEMENT


              THIS AGREEMENT (the "Agreement") is made and entered into this
____ day of _______________, 1997 between American Physician Partners, Inc., a
Delaware corporation (the "Company") and ____________________ ("Indemnitee").

                                WITNESSETH THAT:

              WHEREAS, Indemnitee performs a valuable service for the Company;
and

              WHEREAS, the Board of Directors of the Company have adopted a
Restated Certificate of Incorporation (the "Certificate") permitting the Board
of Directors to indemnify the officers and directors of the Company; and

              WHEREAS, the Certificate and Section 145 of the Delaware General
Corporation Law, as amended ("Law"), by their nonexclusive nature permit
contracts between the Company and the officers and directors of the Company
with respect to indemnification of such officers and directors; and

              WHEREAS, in accordance with the authorization as provided by the
Law, the Company may purchase and maintain a policy or policies of directors'
and officers' liability insurance ("D & O Insurance"), covering certain
liabilities which may be incurred by its officers and directors in the
performance of their obligations as officers and directors of the Company; and

              WHEREAS, as a result of recent developments affecting the terms,
scope and availability of D & O Insurance there exists general uncertainty as
to the extent of protection afforded the Company's officers and directors by
such D & O Insurance and said uncertainty also exists under statutory and bylaw
indemnification provisions; and

              WHEREAS, in recognition of past services and in order to induce
Indemnitee to continue to serve as an officer and/or a director of the Company,
the Company has determined and agreed to enter into this contract with
Indemnitee;

              NOW, THEREFORE, in consideration of Indemnitee's continued
service as an officer and/or a director after the date hereof, the parties
hereto agree as follows:

              1.     INDEMNITY OF INDEMNITEE.  The Company hereby agrees to
hold harmless and indemnify Indemnitee to the full extent authorized or
permitted by the provisions of the Law, as such may be amended from time to
time, and Article VI of the Certificate, as such may be amended.  In
furtherance of the foregoing indemnification, and without limiting the
generality thereof:

                     (a)    Proceedings Other Than Proceedings by or in the
Right of the Company.  Indemnitee shall be entitled to the rights of
indemnification provided in this
<PAGE>   2
Section 1(a) if, by reason of his Corporate Status (as hereinafter defined), he
is, or is threatened to be made, a party to or participant in any Proceeding
(as hereinafter defined) other than a Proceeding by or in the right of the
Company.  Pursuant to this Section 1(a), Indemnitee shall be indemnified
against all Expenses (as hereinafter defined), judgments, penalties, fines and
amounts paid in settlement actually and reasonably incurred by him or on his
behalf in connection with such Proceeding or any claim, issue or matter
therein, if he acted in good faith and in a manner he reasonably believed to be
in or not opposed to the best interests of the Company and, with respect to any
criminal Proceeding, had no reasonable cause to believe his conduct was
unlawful.

                     (b)    Proceedings by or in the Right of the Company.
Indemnitee shall be entitled to the rights of indemnification provided in this
Section 1(b) if, by reason of his Corporate Status, he is, or is threatened to
be made, a party to or participant in any Proceeding brought by or in the right
of the Company to procure a judgment in its favor.  Pursuant to this Section
1(b), Indemnitee shall be indemnified against all Expenses actually and
reasonably incurred by him or on his behalf in connection with such Proceeding
if he acted in good faith and in a manner he reasonably believed to be in or
not opposed to the best interests of the Company; provided, however, that, if
applicable law so provides, no indemnification against such Expenses shall be
made in respect of any claim, issue or matter in such Proceeding as to which
Indemnitee shall have been adjudged to be liable to the Company unless and to
the extent that the Court of Chancery of the State of Delaware, or the court in
which such Proceeding shall have been brought or is pending, shall determine
that such indemnification may be made.

                     (c)    Indemnification for Expenses of a Party Who is
Wholly or Partly Successful.  Notwithstanding any other provision of this
Agreement, to the extent that Indemnitee is, by reason of his Corporate Status,
a party to and is successful, on the merits or otherwise, in any Proceeding, he
shall be indemnified to the maximum extent permitted by law against all
Expenses actually and reasonably incurred by him or on his behalf in connection
therewith.  If Indemnitee is not wholly successful in such Proceeding but is
successful, on the merits or otherwise, as to one or more but less than all
claims, issues or matters in such Proceeding, the Company shall indemnify
Indemnitee against all Expenses actually and reasonably incurred by him or on
his behalf in connection with each successfully resolved claim, issue or
matter.  For purposes of this Section and without limitation, the termination
of any claim, issue or matter in such a Proceeding by dismissal, with or
without prejudice, shall be deemed to be a successful result as to such claim,
issue or matter.

              2.     ADDITIONAL INDEMNITY.

                     (a)    Subject only to the exclusions set forth in Section
2(b) hereof, the Company hereby further agrees to hold harmless and indemnify
Indemnitee against any and all Expenses, judgments, penalties, fines and
amounts paid in settlement actually and reasonably incurred by Indemnitee in
connection with any Proceeding (including an action by or on behalf of the
Company) to which Indemnitee is, was or at any time becomes a party, or is
threatened to be made a party, by reason of his Corporate Status; provided,
however, that with respect to actions by or on behalf of the Company,
indemnification of Indemnitee against any judgments shall be made by the
Company only as authorized in the specific case upon a determination that
Indemnitee acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Company; and

                     (b)    No indemnity pursuant to this Section 2 shall be
paid by the Company:

                            (i)    In respect to remuneration paid to
Indemnitee if it shall be determined by a final judgment or other final
adjudication that such remuneration was in violation of law;

                            (ii)   On account of any suit in which judgment is
rendered against Indemnitee for an accounting of profits made from the purchase
or sale by Indemnitee of securities of the Company pursuant to the provisions
of Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto
or similar provisions of any federal, state or local statutory law;

                            (iii)  On account of Indemnitee's conduct which is
finally adjudged to have been knowingly fraudulent or deliberately dishonest,
or to constitute willful misconduct; or

                            (iv)   If a final decision by a court having
jurisdiction in the matter shall determine that such indemnification is not
lawful.

              3.     CONTRIBUTION.   If the indemnification provided in
Sections 1 and 2 is unavailable and may not be paid to Indemnitee for any
reason other than those set forth in paragraphs (i), (ii) and (iii) of Section
2(b), then in respect to any Proceeding in which the Company is jointly liable
with Indemnitee (or would be if joined in such Proceeding), the Company shall
contribute to the amount of Expenses, judgments, fines and amounts paid in
settlement actually and reasonably incurred and paid or payable by Indemnitee
in such proportion as is appropriate to reflect (i) the relative benefits
received by the Company on the one hand and by the Indemnitee on the other hand
from the transaction from which such Proceeding arose, and (ii) the relative
fault of the Company on the one hand and of the Indemnitee on the other hand in
connection with the events which resulted in such Expenses, judgments, fines or
settlement amounts, as well as any other relevant equitable





                                       3.
<PAGE>   4
considerations.  The relative fault of the Company on the one hand and of the
Indemnitee on the other hand shall be determined by reference to, among other
things, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent the circumstances resulting in such Expenses,
judgments, fines or settlement amounts.  The Company agrees that it would not
be just and equitable if contribution pursuant to this Section 3 were
determined by pro rata allocation or any other method of allocation which does
not take account of the foregoing equitable considerations.

              4.     INDEMNIFICATION FOR EXPENSES OF A WITNESS.
Notwithstanding any other provision of this Agreement, to the extent that
Indemnitee is, by reason of his Corporate Status, a witness in any Proceeding
to which Indemnitee is not a party, he shall be indemnified against all
Expenses actually and reasonably incurred by him or on his behalf in connection
therewith.

              5.     ADVANCEMENT OF EXPENSES.  Notwithstanding any other
provision of this Agreement, the Company shall advance all reasonable Expenses
incurred by or on behalf of Indemnitee in connection with any Proceeding by
reason of Indemnitee's Corporate Status within ten days after the receipt by
the Company of a statement or statements from Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding.  Such statement or statements shall reasonably
evidence the Expenses incurred by Indemnitee and shall include or be preceded
or accompanied by an undertaking by or on behalf of Indemnitee to repay any
Expenses advanced if it shall ultimately be determined that Indemnitee is not
entitled to be indemnified against such Expenses.  Any advances and
undertakings to repay pursuant to this Section 5 shall be unsecured and
interest free.  Notwithstanding the foregoing, the obligation of the Company to
advance Expenses pursuant to this Section 5 shall be subject to the condition
that, if, when and to the extent that the Company determines that Indemnitee
would not be permitted to be indemnified under applicable law, the Company
shall be entitled to be reimbursed, within thirty (30) days of such
determination, by Indemnitee (who hereby agrees to reimburse the Company) for
all such amounts theretofore paid; provided, however, that if Indemnitee has
commenced or thereafter commences legal proceedings in a court of competent
jurisdiction to secure a determination that Indemnitee should be indemnified
under applicable law, any determination made by the Company that Indemnitee
would not be permitted to be indemnified under applicable law shall not be
binding and Indemnitee shall not be required to reimburse the Company for any
advance of Expenses until a final judicial determination is made with respect
thereto (as to which all rights of appeal therefrom have been exhausted or
lapsed).

              6.     PROCEDURE FOR DETERMINATION OF ENTITLEMENT TO
INDEMNIFICATION.

                     (a)    To obtain indemnification (including, but not
limited to, the advancement of Expenses and contribution by the Company) under
this Agreement, Indemnitee shall submit to the Company a written request,
including therein or therewith such documentation and information as is
reasonably available to Indemnitee and is reasonably necessary to determine
whether and to what extent Indemnitee is entitled to indemnification.  The
Secretary of the Company shall, promptly upon receipt of such a request for
indemnification, advise the Board of Directors in writing that Indemnitee has
requested indemnification.

                     (b)    Upon written request by Indemnitee for
indemnification pursuant to the first sentence of Section 6(a) hereof, a
determination, if required by applicable law, with respect to Indemnitee's
entitlement thereto shall be made in the specific case:  (i) if a Change in
Control (as hereinafter defined) shall have occurred, by Independent Counsel
(as hereinafter defined) in a written opinion to the Board of Directors, a copy
of which shall be delivered to Indemnitee (unless Indemnitee shall request that
such determination be made by the Board of Directors or the stockholders, in
which case the determination shall be made in the manner provided in Clause
(ii) below), or (ii) if a Change in Control shall not have occurred, (A) by the
Board of Directors by a majority vote of a quorum consisting of Disinterested
Directors (as hereinafter defined), or (B) if a quorum of the Board of
Directors consisting of Disinterested Directors is not obtainable or, even if
obtainable, if said Disinterested Directors so direct, by Independent Counsel
in a written opinion to the Board of Directors, a copy of which shall be
delivered to Indemnitee, or (C) if so directed by said Disinterested Directors,
by the stockholders of the Company; and, if it is determined that Indemnitee is
entitled to indemnification, payment to Indemnitee shall be made within ten
(10) days after such determination.  Indemnitee shall cooperate with the
person, persons or entity making such determination with respect to
Indemnitee's entitlement to indemnification, including providing to such
person, persons or entity upon reasonable advance request any documentation or
information which is not privileged or otherwise protected from disclosure and
which is reasonably available to Indemnitee and reasonably necessary to such
determination.  Any Independent Counsel, member of the Board of Directors, or
stockholder of the Company shall act reasonably and in good faith in making a
determination under the Agreement of the Indemnitee's entitlement to
indemnification.  Any costs or expenses (including attorneys' fees and
disbursements) incurred by Indemnitee in so cooperating with the person,
persons or entity making such determination shall be borne by the Company
(irrespective of the determination as to Indemnitee's entitlement to
indemnification) and the Company hereby indemnifies and agrees to hold
Indemnitee harmless therefrom.

                     (c)    If the determination of entitlement to
indemnification is to be made by Independent Counsel pursuant to Section 6(b)
hereof, the Independent Counsel shall be selected as provided in this Section
6(c).  If a Change in Control shall not have occurred, the Independent Counsel
shall be selected by the Board of Directors, and the





                                       5.
<PAGE>   6
Company shall give written notice to Indemnitee advising him of the identity of
the Independent Counsel so selected.  If a Change in Control shall have
occurred, the Independent Counsel shall be selected by Indemnitee (unless
Indemnitee shall request that such selection be made by the Board of Directors,
in which event the preceding sentence shall apply), and Indemnitee shall give
written notice to the Company advising it of the identity of the Independent
Counsel so selected.  In either event, Indemnitee or the Company, as the case
may be, may, within 10 days after such written notice of selection shall have
been given, deliver to the Company or to Indemnitee, as the case may be, a
written objection to such selection; provided, however, that such objection may
be asserted only on the ground that the Independent Counsel so selected does
not meet the requirements of "Independent Counsel" as defined in Section 14 of
this Agreement, and the objection shall set forth with particularity the
factual basis of such assertion.  Absent a proper and timely objection, the
person so selected shall act as Independent Counsel.  If a written objection is
made and substantiated, the Independent Counsel selected may not serve as
Independent Counsel unless and until such objection is withdrawn or a court has
determined that such objection is without merit.  If, within 20 days after
submission by Indemnitee of a written request for indemnification pursuant to
Section 6(a) hereof, no Independent Counsel shall have been selected and not
objected to, either the Company or Indemnitee may petition the Court of
Chancery of the State of Delaware or other court of competent jurisdiction for
resolution of any objection which shall have been made by the Company or
Indemnitee to the other's selection of Independent Counsel and/or for the
appointment as Independent Counsel of a person selected by the court or by such
other person as the court shall designate, and the person with respect to whom
all objections are so resolved or the person so appointed shall act as
Independent Counsel under Section 6(b) hereof.  The Company shall pay any and
all reasonable fees and expenses of Independent Counsel incurred by such
Independent Counsel in connection with acting pursuant to Section 6(b) hereof,
and the Company shall pay all reasonable fees and expenses incident to the
procedures of this Section 6(c), regardless of the manner in which such
Independent Counsel was selected or appointed.  Upon the due commencement of
any judicial proceeding or arbitration pursuant to Section 8(a)(iii) of this
Agreement, Independent Counsel shall be discharged and relieved of any further
responsibility in such capacity (subject to the applicable standards of
professional conduct then prevailing).

                     (d)    The Company shall not be required to obtain the
consent of the Indemnitee to the settlement of any Proceeding which the Company
has undertaken to defend if the Company assumes full and sole responsibility
for such settlement and the settlement grants the Indemnitee a complete and
unqualified release in respect of the potential liability.

             7.     PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS.

                     (a)    In making a determination with respect to
entitlement to indemnification hereunder, the person or persons or entity
making such determination shall presume that Indemnitee is entitled to
indemnification under this Agreement if Indemnitee





                                       6.
<PAGE>   7
has submitted a request for indemnification in accordance with Section 6(a) of
this Agreement, and the Company shall have the burden of proof to overcome that
presumption in connection with the making by any person, persons or entity of
any determination contrary to that presumption.

                     (b)    If the person, persons or entity empowered or
selected under Section 6 of this Agreement to determine whether Indemnitee is
entitled to indemnification shall not have made a determination within thirty
(30) days after receipt by the Company of the request therefor, the requisite
determination of entitlement to indemnification shall be deemed to have been
made and Indemnitee shall be entitled to such indemnification, absent (i) a
misstatement by Indemnitee of a material fact, or an omission of a material
fact necessary to make Indemnitee's statement not materially misleading, in
connection with the request for indemnification, or (ii) a prohibition of such
indemnification under applicable law; provided, however, that such 30-day
period may be extended for a reasonable time, not to exceed an additional
fifteen (15) days, if the person, persons or entity making the determination
with respect to entitlement to indemnification in good faith requires such
additional time for the obtaining or evaluating documentation and/or
information relating thereto; and provided, further, that the foregoing
provisions of this Section 7(b) shall not apply (i) if the determination of
entitlement to indemnification is to be made by the stockholders pursuant to
Section 6(b) of this Agreement and if (A) within fifteen (15) days after
receipt by the Company of the request for such determination the Board of
Directors or the Disinterested Directors, if appropriate, resolve to submit
such determination to the stockholders for their consideration at an annual
meeting thereof to be held within seventy five (75) days after such receipt and
such determination is made thereat, or (B) a special meeting of stockholders is
called within fifteen (15) days after such receipt for the purpose of making
such determination, such meeting is held for such purpose within sixty (60)
days after having been so called and such determination is made thereat, or
(ii) if the determination of entitlement to indemnification is to be made by
Independent Counsel pursuant to Section 6(b) of this Agreement.

                     (c)    The termination of any Proceeding or of any claim,
issue or matter therein, by judgment, order, settlement (with or without court
approval), conviction, or upon a plea of nolo contendere or its equivalent,
shall not (except as otherwise expressly provided in this Agreement) of itself
adversely affect the right of Indemnitee to indemnification or create a
presumption that Indemnitee did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Company or, with respect to any criminal Proceeding, that Indemnitee had
reasonable cause to believe that his conduct was unlawful.

                     (d)    For purposes of any determination of good faith,
Indemnitee shall be deemed to have acted in good faith if Indemnitee's action
is based on the records or books of account of the Enterprise (as hereinafter
defined), including financial statements, or on information supplied to
Indemnitee by the officers and directors of the Enterprise in the course of
their duties, or on the advice of legal counsel for the Enterprise





                                       7.
<PAGE>   8
or on information or records given or reports made to the Enterprise by an
independent certified public accountant or by an appraiser or other expert
selected with reasonable care by the Enterprise.  In addition, the knowledge
and/or actions, or failure to act, of any director, officer, agent or employee
of the Enterprise shall not be imputed to Indemnitee for purposes of
determining the right to indemnification under this Agreement.  The provisions
of this Section 7(d) shall not be deemed to be exclusive or to limit in any way
the other circumstances in which the Indemnitee may be deemed to have met the
applicable standard of conduct set forth in this Agreement.

              8.     REMEDIES OF INDEMNITEE.

                     (a)    In the event that (i) a determination is made
pursuant to Section 6 of this Agreement that Indemnitee is not entitled to
indemnification under this Agreement, (ii) advancement of Expenses is not
timely made pursuant to Section 5 of this Agreement, (iii) no determination of
entitlement to indemnification shall have been made pursuant to Section 6(b) of
this Agreement within 90 days after receipt by the Company of the request for
indemnification, (iv) payment of indemnification is not made pursuant to
Section 3 or 4 of this Agreement within ten (10) days after receipt by the
Company of a written request therefor, or (v) payment of indemnification is not
made within ten (10) days after a determination has been made that Indemnitee
is entitled to indemnification or such determination is deemed to have been
made pursuant to Section 6 or 7 of this Agreement, Indemnitee shall be entitled
to an adjudication in an appropriate court of the State of Delaware, or in any
other court of competent jurisdiction, of his entitlement to such
indemnification.  Alternatively, Indemnitee, at his option, may seek an award
in arbitration to be conducted by a single arbitrator pursuant to the
Commercial Arbitration Rules of the American Arbitration Association.
Indemnitee shall commence such proceeding seeking an adjudication or an award
in arbitration within 180 days following the date on which Indemnitee first has
the right to commence such proceeding pursuant to this Section 8(a).  The
Company shall not oppose Indemnitee's right to seek any such adjudication or
award in arbitration.

                     (b)    In the event that a determination shall have been
made pursuant to Section 6(b) of this Agreement that Indemnitee is not entitled
to indemnification, any judicial proceeding or arbitration commenced pursuant
to this Section 8 shall be conducted in all respects as a de novo trial, or
arbitration, on the merits and Indemnitee shall not be prejudiced by reason of
that adverse determination.

                     (c)    If a determination shall have been made pursuant to
Section 6(b) of this Agreement that Indemnitee is entitled to indemnification,
the Company shall be bound by such determination in any judicial proceeding or
arbitration commenced pursuant to this Section 8, absent (i) a misstatement by
Indemnitee of a material fact, or an omission of a material fact necessary to
make Indemnitee's statement not materially misleading, in connection with the
request for indemnification, or (ii) a prohibition of such indemnification
under applicable law.





                                       8.
<PAGE>   9
                     (d)    In the event that Indemnitee, pursuant to this
Section 8, seeks a judicial adjudication of or an award in arbitration to
enforce his rights under, or to recover damages for breach of, this Agreement,
Indemnitee shall be entitled to recover from the Company, and shall be
indemnified by the Company against, any and all expenses (of the types
described in the definition of Expenses in Section 16 of this Agreement)
actually and reasonably incurred by him in such judicial adjudication or
arbitration, but only if he prevails therein.  If it shall be determined in
said judicial adjudication or arbitration that Indemnitee is entitled to
receive part but not all of the indemnification sought, the expenses incurred
by Indemnitee in connection with such judicial adjudication or arbitration
shall be appropriately prorated.  The Company shall indemnify Indemnitee
against any and all expenses and, if requested by Indemnitee, shall (within ten
(10) days after receipt by the Company of a written request therefor) advance
such expenses to Indemnitee, which are incurred by Indemnitee in connection
with any action brought by Indemnitee to recover under any directors' and
officers' liability insurance policies maintained by the Company, regardless of
whether Indemnitee ultimately is determined to be entitled to such
indemnification, advancement of expenses or insurance recovery, as the case may
be.

                     (e)    The Company shall be precluded from asserting in
any judicial proceeding or arbitration commenced pursuant to this Section 8
that the procedures and presumptions of this Agreement are not valid, binding
and enforceable and shall stipulate in any such court or before any such
arbitrator that the Company is bound by all the provisions of this Agreement.

              9.     NONEXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE;
SUBROGATION.

                     (a)    The rights of indemnification as provided by this
Agreement shall not be deemed exclusive of any other rights to which Indemnitee
may at any time be entitled under applicable law, the Certificate, any
agreement, a vote of stockholders or a resolution of directors, or otherwise.
No amendment, alteration or repeal of this Agreement or of any provision hereof
shall limit or restrict any right of Indemnitee under this Agreement in respect
of any action taken or omitted by such Indemnitee in his Corporate Status prior
to such amendment, alteration or repeal.  To the extent that a change in the
Law, whether by statute or judicial decision, permits greater indemnification
than would be afforded currently under the Certificate and this Agreement, it
is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits so afforded by such change.  No right or remedy
herein conferred is intended to be exclusive of any other right or remedy, and
every other right and remedy shall be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise.  The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other right or remedy.

                     (b)    To the extent that the Company maintains an
insurance policy or policies providing liability insurance for directors,
officers, employees, or agents or fidu-





                                       9.
<PAGE>   10
ciaries of the Company or of any other corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise which such person serves at
the request of the Company, Indemnitee shall be covered by such policy or
policies in accordance with its or their terms to the maximum extent of the
coverage available for any such director, officer, employee or agent under such
policy or policies.

                     (c)    In the event of any payment under this Agreement,
the Company shall be subrogated to the extent of such payment to all of the
rights of recovery of Indemnitee, who shall execute all papers required and
take all action necessary to secure such rights, including execution of such
documents as are necessary to enable the Company to bring suit to enforce such
rights.

                     (d)    The Company shall not be liable under this
Agreement to make any payment of amounts otherwise indemnifiable hereunder if
and to the extent that Indemnitee has otherwise actually received such payment
under any insurance policy, contract, agreement or otherwise.

              10.    EXCEPTION TO RIGHT OF INDEMNIFICATION.  Notwithstanding
any other provision of this Agreement, Indemnitee shall not be entitled to
indemnification under this Agreement with respect to any Proceeding brought by
Indemnitee, or any claim therein, unless (a) the bringing of such Proceeding or
making of such claim shall have been approved by the Board of Directors or (b)
such Proceeding is being brought by the Indemnitee to assert his rights under
this Agreement.

              11.    DURATION OF AGREEMENT.  All agreements and obligations of
the Company contained herein shall continue during the period Indemnitee is an
officer and/or a director of the Company (or is or was serving at the request
of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise) and shall
continue thereafter so long as Indemnitee shall be subject to any Proceeding
(or any proceeding commenced under Section 8 hereof) by reason of his Corporate
Status, whether or not he is acting or serving in any such capacity at the time
any liability or expense is incurred for which indemnification can be provided
under this Agreement.  This Agreement shall be binding upon and inure to the
benefit of and be enforceable by the parties hereto and their respective
successors (including any direct or indirect successor by purchase, merger,
consolidation or otherwise to all or substantially all of the business or
assets of the Company), assigns, spouses, heirs, executors and personal and
legal representatives.  This Agreement shall continue in effect regardless of
whether Indemnitee continues to serve as an officer and/or a director of the
Company or any other enterprise at the Company's request.

              12.    SECURITY.  To the extent requested by the Indemnitee and
approved by the Board of Directors, the Company may at any time and from time
to time provide security to the Indemnitee for the Company's obligations
hereunder through an irrevocable





                                      10.
<PAGE>   11
bank line of credit, funded trust or other collateral.  Any such security, once
provided to the Indemnitee, may not be revoked or released without the prior
written consent of the Indemnitee.

              13.    ENFORCEMENT.

                     (a)    The Company expressly confirms and agrees that it
has entered into this Agreement and assumed the obligations imposed on it
hereby in order to induce Indemnitee to serve as an officer and/or a director
of the Company, and the Company acknowledges that Indemnitee is relying upon
this Agreement in serving as      an officer and/or a director of the Company.

                     (b)    This Agreement constitutes the entire agreement
between the parties hereto with respect to the subject matter hereof and
supersedes all prior agreements and understandings, oral, written and implied,
between the parties hereto with respect to the subject matter hereof.

              14.    DEFINITIONS.  For purposes of this Agreement:

                     (a)    "Change in Control" means a change in control of
the Company occurring after the date of this Agreement of a nature that would
be required to be reported in response to Item 6(e) of Schedule 14A of
Regulation 14A (or in response to any similar item on any similar schedule or
form) promulgated under the Securities Exchange Act of 1934 (the "Act"),
whether or not the Company is then subject to such reporting requirement;
provided, however, that, without limitation, such a Change in Control shall be
deemed to have occurred if after the date of this Agreement (i) any "person"
(as such term is used in Sections 13(d) and 14(d) of the Act, as amended) other
than a trustee or other fiduciary holding securities under an employee benefit
plan of the Company or a corporation owned directly or indirectly by the
stockholders of the Company in substantially the same proportions as their
ownership of stock of the Company, is or becomes the "beneficial owner" (as
defined in Rule 13d-3 under the Act), directly or indirectly, of securities of
the Company representing 15% or more of the combined voting power of the
Company's then outstanding securities (other than any such person or any
affiliate thereof that is such a 15% beneficial owner as of the date hereof)
without the prior approval of at least two-thirds of the members of the Board
of Directors in office immediately prior to such person attaining such
percentage interest; (ii) there occurs a proxy contest, or the Company is a
party to a merger, consolidation, sale of assets, plan of liquidation or other
reorganization, as a consequence of which members of the Board of Directors in
office immediately prior to such transaction or event constitute less than a
majority of the Board of Directors thereafter; or (iii) during any period of
two consecutive years, other than as a result of an event described in clause
(a)(ii) of this Section 16, individuals who at the beginning of such period
constituted the Board of Directors (including for this purpose any new director
whose election or nomination for election by the Company's stockholders was
approved by a vote of at least two-thirds of the directors





                                      11.
<PAGE>   12
then still in office who were directors at the beginning of such period) cease
for any reason to constitute at least a majority of the Board of Directors.  A
Change in Control shall not be deemed to have occurred under item (i) above if
the "person" described under item (i) is entitled to report its ownership on
Schedule 13G promulgated under the Act and such person is able to represent
that it acquired such securities in the ordinary course of its business and not
with the purpose nor with the effect of changing or influencing the control of
the Company, nor in connection with or as a participant in any transaction
having such purpose or effect.  If the "person" referred to in the previous
sentence would at any time not be entitled to continue to report such ownership
on Schedule 13G pursuant to Rule 13d-1(b)(3)(i)(B) of the Act, then a Change in
Control shall be deemed to have occurred at such time.

                     (b)    "Corporate Status" describes the status of a person
who is or was a director, officer, employee or agent or fiduciary of the
Company or of any other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise which such person is or was serving
at the express written request of the Company.

                     (c)    "Disinterested Director" means a director of the
Company who is not and was not a party to the Proceeding in respect of which
indemnification is sought by Indemnitee.

                     (d)    "Enterprise" shall mean the Company and any other
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise of which Indemnitee is or was serving at the express written request
of the Company as a director, officer, employee, agent or fiduciary.

                     (e)    "Expenses" shall include all reasonable attorneys'
fees, retainers, court costs, transcript costs, fees of experts, witness fees,
travel expenses, duplicating costs, printing and binding costs, telephone
charges, postage, delivery service fees, and all other disbursements or
expenses of the types customarily incurred in connection with prosecuting,
defending, preparing to prosecute or defend, investigating, participating, or
being or preparing to be a witness in a Proceeding.

                     (f)    "Independent Counsel" means a law firm, or a member
of a law firm, that is experienced in matters of corporation law and neither
presently is, nor in the past five years has been, retained to represent: (i)
the Company or Indemnitee in any matter material to either such party (other
than with respect to matters concerning the Indemnitee under this Agreement, or
of other indemnitees under similar indemnification agreements), or (ii) any
other party to the Proceeding giving rise to a claim for indemnification
hereunder.  Notwithstanding the foregoing, the term "Independent Counsel" shall
not include any person who, under the applicable standards of professional
conduct then prevailing, would have a conflict of interest in representing
either the Company or Indemnitee in an action to determine Indemnitee's rights
under this Agreement.  The Company agrees to pay the reasonable fees of the
Independent Counsel referred to above





                                      12.
<PAGE>   13
and to fully indemnify such counsel against any and all Expenses, claims,
liabilities and damages arising out of or relating to this Agreement or its
engagement pursuant hereto.

                     (g)    "Proceeding" includes any threatened, pending or
completed action, suit, arbitration, alternate dispute resolution mechanism,
investigation, inquiry, administrative hearing or any other actual, threatened
or completed proceeding, whether brought by or in the right of the Company or
otherwise and whether civil, criminal, administrative or investigative, in
which Indemnitee was, is or will be involved as a party or otherwise, by reason
of the fact that Indemnitee is or was an officer and/or a director of the
Company, by reason of any action taken by him or of any inaction on his part
while acting as an officer and/or a director of the Company, or by reason of
the fact that he is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise; in each case whether or not he is acting or serving
in any such capacity at the time any liability or expense is incurred for which
indemnification can be provided under this Agreement; including one pending on
or before the date of this Agreement; and excluding one initiated by an
Indemnitee pursuant to Section 8 of this Agreement to enforce his rights under
this Agreement.

              15.    SEVERABILITY.  If any provision or provisions of this
Agreement shall be held by a court of competent jurisdiction to be invalid,
void, illegal or otherwise unenforceable for any reason whatsoever:  (a) the
validity, legality and enforceability of the remaining provisions of this
Agreement (including without limitation, each portion of any section of this
Agreement containing any such provision held to be invalid, illegal or
unenforceable, that is not itself invalid, illegal or unenforceable) shall not
in any way be affected or impaired thereby and shall remain enforceable to the
fullest extent permitted by law; and (b) to the fullest extent possible, the
provisions of this Agreement (including, without limitation, each portion of
any section of this Agreement containing any such provision held to be invalid,
illegal or unenforceable, that is not itself invalid, illegal or unenforceable)
shall be construed so as to give effect to the intent manifested thereby.

              16.    MODIFICATION AND WAIVER.  No supplement, modification,
termination or amendment of this Agreement shall be binding unless executed in
writing by both of the parties hereto.  No waiver of any of the provisions of
this Agreement shall be deemed or shall constitute a waiver of any other
provisions hereof (whether or not similar) nor shall such waiver constitute a
continuing waiver.

              17.    NOTICE BY INDEMNITEE.  Indemnitee agrees promptly to
notify the Company in writing upon being served with any summons, citation,
subpoena, complaint, indictment, information or other document relating to any
Proceeding or matter which may be subject to indemnification covered hereunder.
The failure to so notify the Company shall not relieve the Company of any
obligation which it may have to the Indemnitee under this Agreement or
otherwise.

                              CONSULTING AGREEMENT


         This CONSULTING AGREEMENT (the "Agreement") is entered into as of
August 21, 1997, by and between American Physician Partners, Inc., a Delaware
corporation (the "Company"), and Michael L. Sherman, M.D., a resident of the
state of Maryland (the "Consultant").

                                    RECITALS

         The Consultant has gained valuable management knowledge and experience 
as the President of Advanced Radiology, L.L.C. and as a radiologist.

         The Company desires to benefit from such knowledge and experience by
obtaining consulting services from the Consultant, and the Consultant is
willing to provide such consulting services to the Company.

                                   AGREEMENT

         Based on the recitals set forth above and the mutual promises
contained herein, the parties agree as follows:

                                   ARTICLE 1

         1.1 Engagement. The Company hereby engages the Consultant as
         consultant and advisor, effective as of the date immediately following
         the consummation of the Company's initial public offering (the
         "Effective Time"), with respect to the matters specified herein,
         subject to the terms and conditions hereof, and for the compensation
         provided herein. The Consultant accepts this engagement, effective as
         of the Effective Time, as a consultant and advisor to the Company,
         subject to the terms and conditions hereof.

         1.2  Tasks and Duties.

              (a) Commitment.  Throughout the Term (defined below), the 
                  Consultant, on a part-time basis, shall devote his
                  professional time, energy, skill and efforts to the
                  performance of the Consultant's tasks and duties hereunder in
                  a manner that will faithfully and diligently further the
                  business and interests of the Company, its subsidiaries and
                  the medical practices, diagnostic imaging centers and other
                  entities affiliated or that potentially may be affiliated
                  with the Company. The Company recognizes that the Consultant
                  (i) shall continue as the President of the professional
                  entity that succeeds Advanced Radiology, L.L.C. (the
                  "Advanced Professional Entity") following the Effective Time,
                  (ii) shall continue to provide medical services, and (iii)
                  (so long as there is not any breach of any restrictive
                  covenant between the Company and the Consultant including,

<PAGE>   2

                  but not limited to, (i) the restrictions regarding
                  non-solicitation and non-competition set forth in this
                  Agreement and the exhibit hereto, (ii) the Consultant's
                  employment agreement with the Advanced Professional Entity,
                  (iii) the Service Agreement between the Company and the
                  Advanced Professional Entity or (iv) the Agreement and Plan
                  of Reorganization and Merger by and between Advanced
                  Radiology, L.L.C. and the Company (collectively, the
                  "Restrictive Covenants") may pursue other professional and
                  business efforts. The Consultant, without his prior written
                  consent, shall not be required to commit more than twenty
                  percent (20%) of his annual professional time providing
                  services under this Agreement.

              (b) Tasks and Responsibilities of Parties.  During the Term 
                  hereof, Consultant will be subject to the general direction
                  of the Company and will perform the consulting services
                  requested by the Company, at times and places as are mutually
                  agreed upon by Consultant and the Company; provided, however,
                  that Consultant, subject to his other responsibilities and
                  long-standing commitments, shall be available for
                  assignments, meetings, and other projects during reasonable
                  business hours with reasonable advance notice from the
                  Company. Consultant's duties shall include, but not be
                  limited to, assisting the Company in recruiting, screening,
                  evaluating and recommending radiology practices and imaging
                  centers for affiliation with or acquisition by the Company.
                  In addition, Consultant shall assist the Company in its
                  efforts to develop and expand its (i) networks through the
                  addition of hospitals and/or managed care organizations, (ii)
                  strategic alliances with other health care providers and
                  payors, (iii) relationships with equipment and supply vendors
                  and (iv) plan for outsourcing imaging services from

                  apply reasonable efforts and skills to his duties hereunder
                  and shall make available to the Company his judgment and
                  experience in the areas of radiology and radiology management
                  services.

              (d) Cooperation.  The Consultant shall use diligent efforts to aid
                  the Company, its subsidiaries, and the medical practices they
                  affiliate with in establishing and maintaining the Company's
                  and its subsidiaries' goodwill and reputation with other
                  medical groups, suppliers, customers, creditors, and the
                  investment and business communities generally.

         1.3 Term. The Term (herein so called) hereof shall be for a period of
         three years, commencing on the date immediately following the
         consummation of the Company's initial public offering.

         1.4  Compensation and Expenses.

              (a) Compensation.  Subject to the terms and conditions hereof, in
                  consideration of the consulting services to be rendered by
                  the Consultant to the Company hereunder, and in consideration
                  of the covenants of the Consultant set forth herein, the
                  Company hereby agrees to pay the Consultant as compensation
                  $100,000 per annum, payable monthly. The Consultant shall be
                  responsible for all federal, state and local income taxes,
                  Social Security, FICA, FUTA and other amounts required by
                  law.

              (b) Payment and Reimbursement of Expenses.  During the Term, the
                  Company shall pay or reimburse the Consultant for all
                  reasonable travel and other expenses incurred by the
                  Consultant in performing the Consultant's obligations
                  hereunder in accordance with the policies and procedures of
                  the Company for its consultants, provided that the Consultant
                  properly accounts therefor in accordance with the regular
                  policies of the Company. Any single expense (other than an
                  air fare shown to be the best rate then available) in excess
                  of the greater of (i) the threshold amount established by the
                  Company immediately following the commencement of the
                  Consultant's duties hereunder and on or near the annual
                  anniversary of such date during the Term or (ii) $1,000
                  individually shall be approved in advance by the Company in
                  writing.

              (c) Annual Review.  On each anniversary of the date of this
                  Agreement, the Board of Directors will review Consultant's
                  performance and establish assignments for the Consultant
                  hereunder for the up-coming year.

              (d) Stock Options for Board of Directors.  The compensation 
                  provided to the Consultant by this Agreement shall be
                  distinct and separate from any stock option grants or other
                  compensation hereafter committed to be made by the Company to
                  the Consultant for service upon the Company's Board of
                  Directors or any committee thereof.

         1.5 Independent Contractor. While serving as a Consultant, the
         Consultant shall at all times be an independent contractor rather than
         a co-venturer, agent, employee or representative of the Company or its
         subsidiaries and, as a result, Consultant shall have no authority to
         bind the Company.

         1.6 Termination. This Agreement will terminate upon the occurrence of
         any of the following events:

              (a) the Consultant dies;

              (b) the Company, by written notice to the Consultant or his
                  court-appointed guardian, after a determination by the
                  Company's Board of Directors, terminates this Agreement due
                  to the inability of the Consultant to perform the duties,
                  tasks and responsibilities under this Agreement for a period
                  exceeding 90 days by reason of injury, physical or mental
                  illness

                  or other disability, which condition has been certified by a
                  physician; provided, however, that prior to terminating this
                  Agreement due to such disability, the Company shall give a
                  written statement of findings to the Consultant or his
                  court-appointed guardian setting forth specifically the
                  nature of the disability and the resulting performance
                  failures, and the Consultant shall have a period of twenty
                  (20) days thereafter to respond in writing to the Board of
                  Directors' findings;

              (c) the Consultant is convicted of (or pleads guilty or nolo
                  contendre to) a felony or any misdemeanor involving
                  dishonesty or moral turpitude; after a determination by the
                  Company's Board of Directors, provided, however, that prior
                  to terminating this Agreement pursuant to this subsection,
                  the Company shall give a written statement of findings to the
                  Consultant setting forth specifically the grounds on which
                  cause is based, and the Consultant shall have a period of
                  twenty (20) days thereafter to respond in writing to the
                  Board of Directors' findings;

              (d) the willful and continued failure of the Consultant to
                  substantially perform his services pursuant to the terms of
                  this Agreement (other than any such failure resulting from
                  illness or disability) after a written demand for substantial
                  performance is requested by the Company's Board of Directors,
                  which demand specifically identifies the manner in which it
                  is claimed that (i) the Consultant has not substantially
                  performed his duties or (ii) the Consultant is willfully
                  engaged in misconduct which has, or can reasonably be
                  expected to have, a direct and material adverse monetary
                  effect on the Company.

              (e) The Consultant terminates this Agreement due to the default by
                  the Company in the performance of any of its obligations
                  hereunder and such default remains unremedied by the Company
                  for a period of twenty (20) days following its receipt of
                  written notice thereof from the Consultant;

              (f) The Consultant voluntarily terminates this Agreement for any
                  reason upon at least 30 days advance written notice;

              (g) The Consultant breaches any Restrictive Covenant; or

              (h) For purposes of this section, no act or failure to act on the
                  Consultant's part shall be considered "willful" if done, or
                  omitted to be done by the Consultant in good faith and with
                  reasonable belief that the Consultant's action or omission
                  was in the best interest of the Company. No termination shall
                  be effected under subsections (d) or (g) unless the
                  Consultant has been provided with specific information in the
                  form of a notice as to the acts or omissions which form the
                  basis of the allegation of the reasons for termination and
                  the Consultant has had an opportunity to be heard, with
                  counsel if so desired, before the Board of Directors and

                  such Board determines, by majority vote, in good faith that
                  the Consultant (i) for purposes of subsection (g), breached a
                  Restrictive Convenant and failed to cure such breach within
                  20 days of such notice or (ii) for purposes of subsection
                  (c), was guilty of conduct resulting in the basis of
                  termination under such subsection, specifying the particulars
                  thereof in detail.

         1.7  Effects of Termination.

              (a) Upon termination of this Agreement for any reason, the
                  Company will pay the Consultant all compensation owed to the
                  Consultant and unpaid through the date of termination
                  (including expense reimbursements).

              (b) In addition, if this Agreement is terminated under Section 
                  1.6 (e), then the Company shall also pay the Consultant a
                  lump sum equal to the number of months remaining in the
                  original Term from the termination date at the
                  then-applicable annual rate.

              (c) Upon termination of this Agreement for any reason (other
                  than under Section 1.6(e)), the Consultant agrees that for
                  the one-year period following the termination of this
                  Agreement:

                  (i)   The Consultant shall not directly or indirectly, whether
                        as an individual, employee, director, consultant or
                        advisor, or in any other capacity whatsoever, provide
                        services to any person, firm, corporation or other
                        business enterprise (other than the Advanced
                        Professional Entity or its affiliated entities;
                        provided, that the Advanced Professional Entity or any
                        of its affiliated entities remains a party to and is in
                        compliance with a service agreement with the Company)
                        which is involved in the acquisition or management of
                        radiology physician practices or other service company
                        that provides management services in the area of
                        radiology where the Company is operating at the time of
                        termination, unless the Consultant obtains the prior
                        written consent of the Company's Board of Directors.

                  (ii)  The Consultant will not directly or indirectly encourage
                        or solicit, or attempt to encourage or solicit, any
                        individual to leave the Company's employ for any reason
                        or materially interfere with the employment
                        relationships at the time existing between the Company
                        and its current or prospective (individuals involved in
                        discussions with the Company regarding employment
                        arrangements) employees.

                  (iii) The Consultant will not induce or attempt to induce any
                        provider, payor, customer, supplier, distributor,
                        licensee or other business relation of the Company to
                        cease doing business with the Company or materially
                        interfere with the existing business relationship
                        between any 




                                       5
<PAGE>   6

                        such customer, supplier, distributor, licensee or other
                        business relation and the Company.

         The Consultant acknowledges that monetary damages may not be
         sufficient to compensate the Company for any economic loss which may
         be incurred by reason of breach of the foregoing restrictive
         covenants. Accordingly, in the event of any such breach, the Company
         shall, in addition to any remedies available to the Company at law, be
         entitled to obtain equitable relief in the form of an injunction
         precluding the Consultant from continuing to engage in such breach. If
         any restriction set forth in this paragraph is held to be
         unreasonable, then the Consultant and the Company agree, and hereby
         submit, to the reduction and limitation of such prohibition to such
         area or period as shall be deemed reasonable.

         1.8  General Provisions.

              (a) Assignment. Neither party may assign or delegate any of his
                  or its rights or obligations under this Agreement without the
                  prior written consent of the other party.

              (b) Entire Agreement.  This Agreement, including Exhibit 1 
                  attached hereto, contains the entire agreement between the
                  parties with respect to the subject matter hereof and
                  supersedes any and all prior agreements between the parties
                  relating to such subject matter.

              (c) Modifications. This Agreement may be changed or modified
                  only by an agreement in writing signed by both parties
                  hereto.

              (d) Period of Limitations.  No legal action shall be brought and 
                  no cause of action shall be asserted by or on behalf of the
                  Consultant, the Consultant's spouse, heirs, assigns,
                  executors or personal or legal representatives (collectively,
                  the "Consultant's Affiliates") against the Company or any
                  Company Affiliate (defined below) after the expiration of two
                  years from the date of accrual of such cause of action, and
                  any claim or cause of action of the Consultant or any
                  Consultant Affiliate shall be extinguished and deemed
                  released unless asserted by the timely filing of a legal
                  action within such two-year period.

              (e) Indulgences, Etc.  Neither the failure nor any delay on the 
                  part of either party to exercise any right, remedy, power or
                  privilege hereunder shall operate as a waiver thereof, nor
                  shall any single or partial exercise of any right, remedy,
                  power or privilege preclude any other or further exercise of
                  the same or of any right, remedy, power or privilege, nor
                  shall any waiver of any right, remedy, power, or privilege
                  with respect to any occurrence be construed as a waiver of
                  such right, remedy, power or privilege with respect to any
                  other occurrence.

              (f) Successors and Assigns.  The provisions of this Agreement
                  shall inure to the benefit of, and be binding upon the
                  Company, its successors and permitted assigns, and the
                  purchaser of all or substantially all of the assets of the
                  Company and the Consultant whether or not any such person
                  shall have become a party to this Agreement and have agreed
                  in writing to join and be bound by the terms and conditions
                  hereof.

              (g) Governing Law.  This Agreement shall be governed by and
                  construed, interpreted and applied in accordance with the
                  laws of the State of Maryland, excluding any choice-of-law
                  rules that would refer the matter to the laws of another
                  jurisdiction.

              (h) Provisions Separable.  The provisions hereof are independent
                  of and separable from each other, and no provision shall be
                  affected or rendered invalid or unenforceable by virtue of
                  the fact that for any reason any other or others of them may
                  be invalid or unenforceable in whole or in part. If any
                  provision hereof, or the application thereof to any situation
                  or circumstance, shall be invalid or unenforceable in whole
                  or in part, then the parties shall seek in good faith to
                  replace any such legally invalid provision or portion thereof
                  with a valid provision that, in effect, will most nearly
                  effectuate the parties' intentions in entering into this
                  Agreement.

              (i) The Consultant's Sole Remedy. The Consultant's sole remedy
                  shall be against the Company (or any assignee or successor to
                  all or substantially all the assets of the Company or any
                  transferee in receipt of material assets of the Company
                  transferred in fraud of creditors (collectively, "Assigns"))
                  for any Consultant Claim (defined below). The Consultant
                  shall have no claim or right of any nature whatsoever against
                  any of the Company's or any of its subsidiaries' directors,
                  officers, employees, direct and indirect stockholders,
                  owners, trustees, beneficiaries or agents, irrespective of
                  when any such person held such status (collectively, the
                  "Company Affiliates") (other than Assigns) arising out of any
                  Consultant Claim (unless the conduct of such persons
                  constitutes intentional or grossly negligent conduct on the
                  part of such persons). The Consultant, on his own behalf and
                  on behalf of the Consultant Affiliates, hereby releases and
                  covenants not to sue any person other than the Company or its
                  Assigns over any Consultant Claim. The Company Affiliates
                  shall be third-party beneficiaries of this Agreement for
                  purposes of enforcing the terms of this Section 1.8(i)
                  ("Consultant's Sole Remedy") against the Consultant and the
                  Consultant Affiliates. Except as set forth in the immediately
                  preceding sentence, nothing herein, express or implied, is
                  intended to confer upon any party, other than the parties
                  hereto, any rights, remedies, obligations or liabilities
                  under or by reason hereof and no person who is not a party
                  hereto may rely on the terms hereof.

                           Upon termination of the Consultant's engagement, the
                  sole claim of the Consultant and the Consultant Affiliates
                  against the Company and its Assigns for the Consultant Claims
                  will be for the amounts described in Section 1.4
                  (Compensation and Expenses) and Section 1.7, as applicable,
                  and the Consultant and the Consultant Affiliates shall have
                  no claim against the Company or its Assigns for any
                  Consultant Claim, other than those set forth in Sections 1.4
                  and 1.7 or against any Company Affiliate (other than Assigns)
                  for the Consultant Claims, including without limitation any
                  claim for damages of any nature, be they actual, direct,
                  indirect, special, punitive or consequential. The Consultant,
                  on his own behalf and on behalf of the Consultant Affiliates,
                  hereby releases and covenants not to sue for, collect or
                  otherwise recover any amount against the Company or its
                  Assigns for any Consultant Claim, other than the amounts set
                  forth in Sections 1.4 and 1.7, or against any Company
                  Affiliate (other than Assigns) for any Consultant Claim.

                           "The Consultant Claim" shall mean any claim,
                  liability or obligation of any nature whatsoever arising out
                  of this Agreement or an alleged breach of this Agreement or
                  the termination of this Agreement; provided, however, that
                  the term "The Consultant Claim" shall not include claims
                  arising in favor of creditors of the Company generally,
                  including claims arising out of any fraudulent conveyance or
                  other transfer of assets in fraud of creditors or claims not
                  directly relating to this Agreement.

         (j)      Indemnification by the Company.

                  (a)      The Company shall indemnify the Consultant who was or
                  is a party or is threatened to be made a party to any
                  threatened, pending or completed action, suit, or proceeding,
                  whether civil, criminal, administrative or investigative
                  (other than an action by or in the right of the Company) by
                  reason of the fact that he is or was a Consultant against
                  expenses (including attorneys' fees), judgments, fines and
                  amounts paid in settlement actually and reasonably incurred
                  by him in connection with such action, suit, or proceeding if
                  he acted in good faith and a manner he reasonably believed to
                  be in or not opposed to the best interests of the Company,
                  and with respect to any criminal action or proceeding, had no
                  reasonable cause to believe his conduct was unlawful. The
                  determination of any action, suit or proceeding by judgment,
                  order, settlement, conviction or upon a plea of nolo
                  contendere or its equivalent, shall not, of itself, create a
                  presumption that the Consultant did not act in good faith and
                  in a manner which he reasonably believed to be in or not
                  opposed to the best interests of the Company, and with
                  respect to any criminal action or proceeding, had reasonable
                  cause to believe that his conduct was unlawful.

<PAGE>   9

                  (b)      Any indemnification under this subsection (j) shall 
                  be made by the Company only as authorized in the specific
                  case upon its determination that indemnification of the
                  Consultant is proper in the circumstances because he has met
                  the applicable standard of conduct set forth in the preceding
                  paragraph. Such determination shall be made (1) by a majority
                  vote of the directors who are not parties to such action,
                  suit, or proceeding, even though less than a quorum, or (2)
                  if there are no such directors or if such directors so
                  direct, by independent legal counsel in a written opinion or
                  (3) by the stockholders. Expenses (including attorneys' fees)
                  incurred by the Consultant in defending any civil, criminal,
                  administrative or investigative action, suit or proceeding
                  shall be paid by the Company following final disposition of
                  such action, suit or proceeding if it is determined that he

                                   EXHIBIT 1

                  CONFIDENTIALITY, PROPRIETARY INFORMATION AND
                              INVENTIONS AGREEMENT

This Agreement (the "Agreement"), is made and entered into as of August 21,
1997 by and between American Physician Partners, Inc., a Delaware corporation
(hereafter together with its affiliates known as the "Company"), and Michael L.
Sherman, M.D. (the "Consultant"), a resident of the State of Maryland as of the
date of this Agreement. In consideration of the Consultant's continued
retention by the Company and in further consideration of the mutual covenants,
promises and conditions set forth in this Agreement and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties agree as follows:

         1.      Treatment of Confidential Information. The Consultant
recognizes and acknowledges that the trade secrets and confidential information
of the Company (the "Proprietary Information"), as they may exist from time to
time, are valuable, special and unique assets of the Company's Business (as
defined below). The Consultant further acknowledges that access to such
Proprietary Information is essential to the performance of the Consultant's
duties as a Company consultant. Therefore, in order to obtain access to such
Proprietary Information, the Consultant agrees that the Consultant will not in
whole or in part, disclose such Proprietary Information to any person, firm,
corporation, association or any other entity for any reason or purpose
whatsoever (other than in furtherance of his duties as Consultant, e.g.,
negotiations with other parties), nor will the Consultant make use of any
such information for the Consultant's own purposes or for the benefit of any
person, firm, corporation, association, or other entity (except the Company,
its directors, officers, employees, attorneys, accountants and other advisors)
under any circumstances. For purposes of this Agreement, the term "trade
secrets" means the whole or any portion of any scientific or technical or
non-technical information, design, process, procedure, formula, computer
software product, documentation or improvement relating to the Company's
Business which (1) derives economic value, actual or potential, from not being
generally known to other persons who can obtain economic value from its
disclosure or use and (2) is the subject of efforts that are reasonable under
the circumstances to maintain its secrecy or confidentiality, including, but
not limited to: (i) any technical or non-technical data, design, process,
procedure, formula, pattern, compilation, program, device, method, technique,
drawing, financial data, financial plan, product plan; (ii) computer software
programs including application operating system, data base, communication and
other computer software whether now or hereafter existing or developed for use
on any operating system; (iii) all modifications, enhancements and all options
available with respect thereto, and all future products developed or derived
therefrom; (iv) source and object codes, flow charts, coding sheets, routines,
subroutines, compilers, assemblers, designs, and related documentation and
manuals; (v) production processes, marketing techniques, arrangements, and
plans, mailing lists, purchasing information, pricing policies, quoting
procedures, financial information, strategies, forecasts, the compensation and
terms of employment of other consultants, customer and prospect names and
requirements,





                                       1
<PAGE>   12
consultant, customer, supplier, and distributor data and other materials or
information; and (vi) results of research and development activities, including
new processes, formulas, inventions, computer related equipment or technology,
and design drawings and specifications.

   
The term "confidential information" means any and all data and information
relating to the Company's Business, other than trade secrets (1) which has
value to the company; (2) is not generally known by its competitors or the
public; and (3) is treated as confidential by the Company. The provisions of
this Section 1 will apply during the Consultant's retention by the Company and
for a three (3)-year period thereafter with respect to confidential
information, and during the Consultant's retention by the Company and at any
and all times thereafter with respect to trade secrets.
    

   
The restrictions of this Section 1 will not apply to any Proprietary
Information which, (a) is, at the time of disclosure, in the public domain,
provided that the Consultant was not responsible, directly or indirectly, for
such Proprietary Information entering the public domain without the Company's
prior written consent, or (b) such Proprietary Information as was known to the
Consultant upon the signing of this Agreement (excluding Proprietary
Information obtained from the Company) or becomes so known to the Consultant
solely from other sources. This Section 1, along with Sections 2, 3, and 4 of
this Agreement will survive any termination of this Agreement.
    

All documents, charts, graphs, notebooks, customer lists, computer disks, tapes
or printouts and other printed, typewritten or handwritten documents, whether
or not pertaining to Proprietary Information (collectively, "Company
Materials") furnished to the Consultant by the Company or the Business or
produced by the Consultant or others in connection with the Consultant's
retention shall be and remain the sole property of the Company. The Consultant
agrees that during the Consultant's retention by the Company, the Consultant
will not remove any Company Materials from the business premises of the Company
or deliver any Company Materials to any person or entity outside the Company,
except in connection with performing the duties of the Consultant's retention
by the Company.

The Consultant acknowledges, warrants and agrees to return to the Company all
Company assets, apparatus, equipment, other physical property, and Proprietary
Information, and Company Materials, in the Consultant's possession or to which
the Consultant has access including, without limitation, documents, drawings,
manuals, specifications, notes, computer programs, and other proprietary
materials, and any copies or excerpts thereof, and any other properties, client
lists, client contracts, files or documents obtained as a result of the
Consultant's retention by the Company immediately upon the termination of the
Consultant's consulting agreement with the Company by the Consultant or the
Company for any reason (or no reason) or during the term of the Consultant's
retention by the Company if requested by the Company; provided, however, that
the Consultant shall not be required to return (i) the Consultant's personal
copies of records relating to the Consultant's compensation, (ii) the
Consultant's personal copies of any materials previously distributed generally
to stockholders of the





                                       2
<PAGE>   13
Company, and (iii) the Consultant's copy of this Agreement. The Company
recognizes that the Consultant is considerably experienced in the Company's
line of business and, while engaged with the Company, shall continue to pursue
compatible endeavors which are reviewed and approved in advance by the
Company's Board of Directors.

         If the Consultant is requested or becomes compelled pursuant to a
civil lawsuit or any criminal investigation, indictment, or proceeding (by oral
questions, interrogatories, requests for information or documents, subpoena,
civil investigative demand or similar process) to disclose any of the
Confidential Information, the Consultant shall provide the Company with prompt
written notice prior to such request or demand for disclosure so that the
Company may seek a protective order or other appropriate remedy and the
Consultant agrees to use his best efforts to assist the Company in such matter.
In the event that such protective order or other remedy is not obtained, the
Company shall furnish only that portion of the Confidential Information that is
legally required, in the opinion of legal counsel reasonably acceptable to the
Company and shall exercise his best efforts to obtain reliable assurance that
confidential treatment will be accorded the Confidential Information.

2.A.     Non-Solicitation Covenants. The Consultant agrees that, during the
Consultant's retention by the Company and for a period of one (1) year
following the termination of the Consultant's consulting agreement for whatever
reason (other than as set forth in Section 1.6(e) therein), the Consultant will
not directly or indirectly, on the Consultant's own behalf or in the service or
on behalf of any other individual or entity, with respect to the business of
the Company, (i) divert, solicit, or attempt to solicit any individual or
entity (a) who is a Client of the Company at any time during the twelve
(12)-month period prior to the Consultant's termination with the Company, or
was within such period actively sought by the Company as a prospective client,
and (b) with whom the Consultant had material contact while retained by the
Company, to provide Business services to such Clients or prospects; or (ii)
divert, solicit or hire away, or attempt to divert, solicit or hire away, to or
for any individual or entity which is engaged in providing Business services,
any person employed by the Company, whether or not such consultant is a
full-time consultant or temporary consultant, whether or not such consultant is
retained pursuant to written agreement and whether or not such consultant is
retained for a determined period or at will. For purposes of this Agreement,
"material contact" exists between the Consultant and each Client or actively
sought prospective client (i) with whom the Consultant dealt on behalf of the
Company; (ii) whose dealings with the Company were coordinated or supervised by
the Consultant; or (iii) about whom the Consultant obtained confidential
information in the course of the Consultant's retention by the Company.

For purposes of this Agreement, (i) "Business" means rendering billing,
accounts receivable, management and collection services, financial management
services, and practice management services to physicians and physician groups;
(ii) "Client" means any individual or entity to whom the Consultant has
provided services at any time during the period of the Consultant's retention
by the Company, as well as any entity employing or made up in part of an
individual who was the recipient (whether directly or indirectly





                                       3
<PAGE>   14
through another entity) of the Company's Business services provided by the
Consultant at any time during the Consultant's retention.

2.B.     Non-Interference. During the Consultant's retention by the Company and
for a one (1)-year period thereafter, the Consultant will not, directly or
indirectly, on the Consultant's own behalf or in the service of or on behalf of
any other individual or entity, interfere with, impair, disrupt, or attempt to
disrupt the Business, for the purpose of assisting a competitor of the Company
or for the purpose of intentionally harming the Company, whether by way of
interfering with (i) or raiding its consultants or employees, (ii) past,
present, or prospective relationships, contractual or otherwise, between the
Company and any supplier, vendor, consultant, distributor, representative, or
(iii) a Client of the Company with whom the Consultant had material contact
during the Consultant's retention. The term "prospective relationship" means
any relationship where the Company has actively sought an individual or entity
as a prospective supplier, consultant or client.

2.C.     Construction. It is the primary goal of the Company to protect its
interests while preserving the Consultant's ability to earn a livelihood in the
Consultant's present domicile and to continue performing the approved
activities set forth in the Consultant's Consulting Agreement with the Company
and such other professional endeavors subject to review and approval in advance
by the Company's Board of Directors. Accordingly, this Section 2 will not
prohibit the Consultant from establishing the Consultant's own company,
provided however, that the Consultant, in any event is bound by Sections 2A and
2B above and by Sections 3 and 4 below. For purposes of these covenants, the
Consultant acknowledges that (i) the Company's business is or may become
national or international in scope, (ii) the number of potential persons and
entities for whom the Consultant can provide Business services (other than
Clients and prospective clients) is vast and consequently these covenants will
not unreasonably impair the Consultant's ability to engage in Business
activities after the termination of the Consultant's retention by the Company,
and (iii) the Consultant's training experience or technical skills are of such
breadth that they can be employed to advantage in other ways and consequently
the foregoing obligation will not unreasonably impair the Consultant's ability
to engage in business activities after the termination of the Consultant's
retention by the Company. The Company recognizes the Consultant's present
professional endeavors. Furthermore, the parties hereto agree that any judicial
authority construing all or any portion of this Section 2 will be empowered to
sever any portion of the applicable area, client base, prospective relationship
or prospect list of any prohibited business activity from the coverage of this
Section and to apply the provisions of this Section to the remaining portion of
the applicable area, the client base or the prospective relationship or
prospect list, or the remaining business activities not so severed by such
judicial authority. In addition, it is the intent of the parties that the
judicial authority replace each severed provision with a provision as similar
in terms to such severed provision as may be possible and be legal, valid, and
enforceable. It is the intent of the parties that this Section be enforced to
the maximum extent permitted by law. In the event that any provision of this
Section is determined not to be specifically enforceable, the Company





                                       4
<PAGE>   15
will nevertheless be entitled to recover monetary damages as a result of the
breach of such provision by the Consultant.

3.       Existing Restrictive Covenants. The Consultant represents and warrants
that the Consultant's retention by the Company, including the performance of
and compliance with all of the terms and provisions of this Agreement, do not
and will not breach any agreement which the Consultant has with any person,
entity, or former employer to keep in confidence confidential information or
not to compete with any such person, entity, or former employer. The Consultant
will not disclose to the Company or use on its behalf any confidential
information of any other party required to be kept confidential by the
Consultant.

4.       Proprietary Rights. During the course of the Consultant's retention by
the Company and in the fulfillment of the Consultant's services to the Company,
and for a period of one (1) year thereafter, the Consultant may, either alone
or jointly with others, make, develop, or have developed or conceive or reduce
to practice any useful process, machine, composition of matter, computer
software or program, algorithm, work of authorship expressing such algorithm,
or any other discovery, document, invention, design, data or improvement which
relates to or is useful to the Company's Business (the "Inventions") whether or
not subject to copyright or patent protection, which relate to or are useful in
the business activities of the Company and which may or may not be considered
Proprietary Information. The Consultant acknowledges that all such Inventions
will be promptly disclosed to the Company's President and will be "works made
for hire" and will remain the sole and exclusive property of the Company. The
Consultant also hereby assigns and agrees to assign to the Company, in
perpetuity, all right, title and interest the Consultant may have in and to
such Inventions, including without limitation, all copyrights, and the right to
apply for any form of patent, utility model, industrial design or similar
proprietary right recognized by any state, country, or jurisdiction. The
Consultant further agrees, at the Company's request and expense, to do all
things and sign all documents or instruments necessary, in the opinion of the
Company, to eliminate any ambiguity as to the ownership of, and rights of the
Company to, such Inventions, including filing copyright and patent
registrations and defending and enforcing in litigation or otherwise all such
rights. The Company shall compensate the Consultant at a reasonable rate after
termination of the consulting agreement for time actually spent by the
Consultant at the Company's request on such assistance. In the event that the
Company is unable for any reason whatsoever to secure the Consultant's
signature to any lawful and necessary documents required to apply for or
execute any patent, copyright, or other applications with respect to such
Inventions and improvements (including renewals, extensions, continuations,
divisions or continuations in part thereof), the Consultant hereby irrevocably
designates and appoints the Company and its duly authorized officers and
agents, and each of them, as the Consultant's agents and attorneys-in-fact to
act for and in the Consultant's behalf and instead of the Consultant, to
execute and file any such application and to do all other lawfully permitted
acts to further the prosecution and issuance of patents, copyrights or other
rights thereof with the same legal force and effect as if executed by the
Consultant. The Consultant will not be obligated to assign to the Company any
Invention made by the Consultant while engaged





                                       5
<PAGE>   16
by the Company which does not relate to any business or activity in which the
Company is or may become engaged, except that the Consultant is so obligated if
the same relates to or is based on Proprietary Information to which the
Consultant will have had access during and by virtue of the Consultant's
employment or which arises out of work assigned to the Consultant by the
Company. The Consultant will not be obligated to assign any Invention which may
be wholly conceived by the Consultant after the Consultant's consulting
agreement with the Company is terminated, except that the Consultant is so
obligated if such Invention involves the utilization of Proprietary Information
obtained while retained by the Company. The Consultant is not obligated to
assign any Invention which relates to or would be useful in any business or
activities in which the Company is engaged if such Invention was conceived and
reduced to practice by the Consultant prior to the Consultant's retention by
the Company.

5.       Remedies. The Consultant agrees and acknowledges that the violation of
any of the covenants or agreements contained in Sections 1, 2, 3 and 4 of this
Agreement would cause irreparable injury to the Company, that the remedy at law
for any such violation or threatened violation thereof would be inadequate and
that the Company will be entitled, in addition to any other remedy, temporary
and permanent injunctive or other equitable relief without the necessity of
proving actual damages or posting a bond. The Consultant also acknowledges that
a breach of any of the terms of this agreement may result in action against the
Consultant, including immediate termination of the Consultant's retention by
the Company.

6.       The Consultant's Status. Nothing in this Agreement will be construed
constituting a commitment, guarantee, agreement, or understanding of any kind
or nature that the Company will continue to retain the Consultant, nor will
this Agreement affect in any way the right of the Company, as expressly
provided therein, to terminate the consulting agreement of the Consultant at
any time and for any reason whatsoever. No change of the Consultant's duties as
a consultant of the Company will result in, or be deemed to be, a modification
of the terms of this Agreement.

7.       Severability. Subject to the application of Section 2.C. to the
interpretation of Section 2, in case one or more of the provisions contained in
this Agreement is for any reason held to be invalid, illegal or unenforceable
in any respect, the same will not affect any other provision in this Agreement,
and this Agreement will be construed as if such invalid or illegal or
unenforceable provision had never been contained herein. It is the intent of
the parties that this Agreement be enforced to the maximum extent permitted by
law.

8.       Miscellaneous. This Agreement and the Consulting Agreement executed
contemporaneously herewith embody the entire Agreement of the parties relating
to the narrow subject matter of this Agreement and specifically supersedes any
previously existing written or verbal, express or implied consulting agreements
between the Consultant and the Company.  No amendment or modification of this
Agreement will be valid or binding upon the parties until made in writing and
signed by the parties. This Agreement will be binding upon the parties and
their respective heirs, representatives,





                                       6
<PAGE>   17
successive transferees and permitted assigns. This Agreement is one for
personal service and will not be assigned by the Consultant. The Company may
assign this Agreement to any of its subsidiaries or affiliated companies,
provided that parent or any subsidiary or Affiliate fulfills the obligations of
the Company under the Consulting Agreement. This Agreement is entered into and
will be interpreted and enforced pursuant to the laws of the State of Texas
(without regard for conflicts of law), as of the date of this Agreement, as
first reflected above.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and
year first above written.

1.102  AGREED RENTABLE AREA. The agreed rentable area of the Premises is hereby
       stipulated to be the "Agreed Rentable Area of the Premises" set forth in
       Item 2b of the Basic Lease Provisions and shall not be changed for any
       reason other than an agreed upon addition or reduction of rentable area
       of the Premises after the date hereof. The agreed rentable area of the
       Tower and the agreed rentable area of the Building are hereby stipulated
       to be the "Agreed Rentable Area of the Tower" and the "Agreed Rentable
       Area of the Building", respectively, set forth in Item 1b of the Basic
       Lease Provisions and shall not be changed for any reason other than an
       agreed upon addition or reduction of rentable area of the Building after
       the date hereof.

1.103  INITIAL TERM AND COMMENCEMENT. The initial term of this Lease shall be
       the period of time specified in Item 6 of the Basic Lease Provisions.
       The initial term shall commence on the Commencement Date set forth in
       Item 7 of the Basic Lease Provisions (as such Commencement Date may be
       adjusted pursuant to Section 3 of the Work Letter (herein so called)
       attached hereto as EXHIBIT D) and, unless sooner terminated pursuant to
       the terms of this Lease, the initial term of this Lease shall expire,
       without notice to Tenant, on the Expiration Date set forth in Item 8 of
       the Basic Lease Provisions.

SECTION 1.2 INSPECTION AND DELIVERY OF PREMISES, CONSTRUCTION OF
LEASE SPACE IMPROVEMENTS AND POSSESSION.

1.201  DELIVERY. Tenant hereby accepts delivery of the Premises. Tenant

       (as hereinafter defined) and, except for latent defects discovered and
       reported to Landlord by Tenant within 180 days from the Commencement
       Date and subject to Landlord's obligations under this Lease, hereby (i)
       accepts the Common Areas in "as is" condition for all purposes and (ii)

<PAGE>   10




1.203  ACCEPTANCE OF PREMISES MEMORANDUM. Upon Substantial Completion (as
       defined in the Work Letter) of Tenant's Improvements, Landlord and
       Tenant shall execute the Acceptance of Premises Memorandum (herein so
       called) attached hereto as EXHIBIT E. If Tenant occupies the Premises
       and commences business therein without executing an Acceptance of
       Premises Memorandum, Tenant shall be deemed to have accepted the
       Premises for all purposes and Substantial Completion shall be deemed to
       have occurred on the earlier to occur of (i) actual occupancy or (ii)
       the Commencement Date set forth in Item 7 of the Basic Lease Provisions.

SECTION 1.3 DELIVERY OF THE PREMISES.

1.301  OBLIGATION TO REDELIVER. Upon the expiration or earlier termination of
       this Lease or upon the exercise by Landlord of its right to re-enter the
       Premises pursuant to subsection 13.202 below and subject to Tenant's
       remaining obligations under this Section, Tenant shall immediately
       deliver to Landlord the Premises free of offensive odors and in a safe,
       clean, neat, sanitary and operational condition (ordinary wear and tear
       and damage caused by condemnation or casualty excepted), together with
       all keys and parking and access cards (it being understood that each
       parking card not returned to Landlord shall be treated as a lost card
       and Tenant shall pay Landlord an amount determined in accordance with
       EXHIBIT F attached to these Supplemental Lease Provisions). Tenant
       shall, upon the expiration or earlier termination of this Lease or
       Landlord's re-entry of the Premises pursuant to subsection 13.202,
       remove from the Premises, at the sole expense of Tenant, all equipment,
       appliances, machinery, trade fixtures, furnishings and personalty
       installed or placed in the Premises by or on behalf of Tenant.
       Notwithstanding the foregoing, if Landlord is exercising its lien rights
       against any such equipment, machinery, fixtures, furnishings and
       personalty, then Tenant shall not remove same from the Premises. If
       requested by Landlord in writing within thirty (30) days after the
       expiration or earlier termination of this Lease or Landlord's re-entry
       of the Premises pursuant to subsection 13.202, Tenant shall remove all
       improvements made to the Premises by or on behalf of Tenant (other than
       Tenant's Improvements and Installations approved by Landlord without the
       written requirement that same be removed upon expiration or earlier
       termination of the Lease) and restore the Premises to the condition
       existing prior to the installation of such improvements (ordinary wear
       and tear and damage caused by condemnation or casualty excepted). All
       removals and work described above shall be accomplished in a good and
       workmanlike manner and shall be conducted in a fashion so as not to
       damage the Premises or the Building or any portion thereof or the
       plumbing, electrical lines or other utilities serving the Building.
       Tenant shall, at its expense, promptly repair any damage caused by any
       such removal or work. If Tenant fails to deliver the Premises in the
       condition aforesaid, then Landlord may restore the Premises to such a
       condition at Tenant's expense. All property required to be removed
       pursuant to this Section not removed within the time period required
       hereunder shall thereupon be conclusively presumed to have been
       abandoned by Tenant and Landlord may, at its option, take over
       possession of such property and either (x) declare the same to be the
       property of Landlord by written notice to Tenant at the address provided
       herein or at such other address which Tenant provides to Landlord in
       accordance with the provisions of Article

       14 below or (y) at the sole cost and expense of Tenant, remove and store
       and/or dispose of the same  or any part thereof in any manner that
       Landlord shall choose without incurring liability to Tenant or any other
       person on account thereof, including damage to such property (EVEN IF
       SUCH DAMAGE IS CAUSED BY THE  NEGLIGENCE OF LANDLORD, LANDLORD'S MOVERS
       OR ANY STORAGE FACILITY).     
                                                                               
1.302  FAILURE TO DELIVER. Notwithstanding any provision or inference to the
       contrary herein contained, in the event that Tenant fails to deliver to
       Landlord (and surrender possession of) all of the Premises upon the
       expiration or earlier termination of this Lease (or the applicable
       portion of the Premises if this Lease expires or terminates as to only a
       portion of the Premises), then Landlord may, without judicial process
       and without notice of any kind, immediately enter upon and take absolute
       possession of the Premises or applicable portion thereof, expel or
       remove Tenant and any other person or entity who may be occupying the
       Premises or applicable portion thereof, change the locks to the Premises
       or applicable portion thereof(in which event, Tenant shall have no right
       to any key for the new locks), limit elevator access to the Premises or
       applicable portion thereof, and take any other actions as are necessary
       for Landlord to take absolute possession of the Premises or applicable
       portion thereof. The foregoing rights are without prejudice and in
       addition to, and shall not in any way limit Landlord's rights under,
       Section 1.4 below or Landlord's remedies under Article 13 below.

SECTION 1.4 HOLDING OVER. In the event Tenant or any party under Tenant
claiming rights to this Lease, retains possession of the Premises after the
expiration or earlier termination of this Lease without the express written
consent of Landlord (each such retention of possession, a "HOLDOVER"), such
Holdover shall constitute and be construed as a tenancy at will only, subject,
however, to all of the terms, provisions, covenants and agreements on the part
of Tenant hereunder. In the event of any such Holdover, the parties holding
over shall be subject to immediate eviction and removal and Tenant or any such
party shall pay Landlord as rent for the period of such holdover an amount
equal to (i) the greater of the fair market rental value of the Premises (as
reasonably determined by Landlord) or one and one-half (1 1/2) times the Basic
Annual Rent in effect immediately preceding expiration or termination of this
Lease, plus (ii) Additional Rent (as hereinafter defined) in effect immediately
preceding expiration or termination of this Lease. Tenant shall also pay any
and all damages (including, without limitation, consequential damages)
sustained by Landlord as a result of such Holdover. The rent during such
Holdover period shall be payable to Landlord from time to time on demand;
provided, however, if no demand is made during a particular month, holdover
rent accruing during such month shall be paid in accordance with the provisions
of Article 2. No holding over by Tenant, whether with or without consent of
Landlord, shall operate to extend the term of this Lease; no payments of money
by Tenant to Landlord after the expiration or earlier termination of this Lease
shall reinstate, continue or extend the Term of this Lease; and no extension of
this Lease after the expiration or earlier termination thereof shall be valid
unless and until the same shall be reduced to writing and signed by both
Landlord and Tenant. If Landlord elects to cause Tenant to be ejected from the
Premises through judicial process and without in any way limiting Landlord's
rights under subsection 1.302 above, Tenant agrees that Landlord will not be
required to deliver Tenant more than one (1) day's notice to vacate prior to
Landlord's filing a forcible detainer suit. In addition, Tenant agrees that
Landlord shall be entitled to the payment of its reasonable legal fees in the
event that Landlord prevails in a forcible detainer action 


                                       3
<PAGE>   12

brought by Landlord. Landlord agrees that Tenant shall be entitled to payment
of its reasonable legal fees in the event that Tenant prevails in a forcible
detainer action brought by Landlord.

                                ARTICLE 2--RENT

SECTION 2.1 BASIC RENT. Tenant shall pay as annual rent for the Premises the
applicable Basic Annual Rent shown in Item 3 of the Basic Lease Provisions. The
Basic Annual Rent shall be payable in monthly installments equal to the
applicable Basic Monthly Rent shown in Item 3 of the Basic Lease Provisions in
advance, without offset, deduction or, except as otherwise expressly provided
herein, demand. The monthly installments of Basic Monthly Rent shall commence
on the Commencement Date and shall continue on the first (1st) day of each
calendar month thereafter. If the Commencement Date occurs on a day other than
the first day of a calendar month or the Expiration Date occurs on a day other
than the last day of a calendar month, the Basic Monthly Rent for such partial
month shall be prorated based on a fraction, the numerator of which shall be
the number of days from the first day of such month through and including the
day of termination and the denominator of which shall be the total number of
days in such month.

        the rental reserved hereunder or on Landlord's business of leasing the
        Premises, excepting only Landlord's income, franchise, death, gift and
        transfer taxes. In the event that Landlord pays any portion of the 
        foregoing as rental under a ground lease arrangement with the fee 
        simple titleholder to the land upon which the Building is, or is to be, 
        constructed, Landlord shall have the right to include same in Real 
        Estate Taxes. In no event will Real Estate Taxes include interest or
        late charges or other costs attributable to Landlord's failure to pay 
        taxes prior to delinquency, unless such interest, late charges or 
        other costs are the result of Landlord's good faith contest of the 
        amount, validity or applicability of such taxes.

 (d)"ADDITIONAL PASS THROUGH COSTS" shall mean the following costs and expenses 
        incurred by Landlord from and after January 1, 1996: (i) subject
        to the limitations of clause (ii) following, the cost of any improvement
        made to the Property by Landlord that is required under any governmental
        law or regulation which was not promulgated, or which was promulgated
        but was not applicable to the Building, at the date of this Lease,
        amortized on a straight line basis over its useful life, together with
        an amount equal to interest at the rate of ten percent (10%) per annum
        (the "AMORTIZATION RATE") on the unamortized balance thereof; (ii) the
        cost of any improvement made to the Common Areas of the Property that is
        required under interpretations or regulations issued after the
        Commencement Date under, or amendments made after the Commencement Date
        to, the provisions of Tex. Rev. Civ. Stat. Ann. art. 9102 and the
        provisions of the Americans With Disabilities Act of 1990, 42
        U.S.C.ss.ss.12101-12213 (collectively, the "DISABILITY ACTS"), amortized
        on a straight-line basis over its useful life, together with an amount
        equal to interest at the Amortization Rate on the unamortized balance
        thereof; (iii) the cost of any labor-saving or energy-saving device or
        other equipment installed in the Building (provided Landlord reasonably
        anticipates that the installation thereof will reduce Operating Costs),
        amortized on a straight-line basis over its useful life, together with
        an amount equal to interest at the Amortization Rate on the unamortized
        balance thereof; and (iv) all other capital costs which are amortizable
        over a period of five (5) years or less, and which would generally be
        viewed as an operating cost.

2.202 Payment of Additional Rent.

     (a) For each calendar year during the Term of this Lease (including any
            extensions thereof), Tenant shall (in accordance with the
            provisions of paragraphs (c), (d),and (e) of this subsection) pay
            to Landlord Additional Rent, which is hereby defined to mean the
            following:

            (i) the amount by which (a) the sum of the per square foot Fixed
                Operating Costs for the applicable calendar year and the per
                square foot Variable Operating Costs Attributable to All
                Tenants for such calendar year, MULTIPLIED BY the square feet
                of Agreed Rentable area of the Premises exceeds (b) Landlord's
                Annual Operating Costs Contribution set forth in Item 4 of the
                Basic Lease Provisions; plus

           (ii) the sum of (a) the per square foot Fixed Energy Costs and the
                per square foot Variable Energy Costs Attributable to All
                Tenants for the applicable calendar year, multiplied by (b) the
                square feet of Agreed Rentable Area of the Premises; plus

          (iii) the amount by which the per square foot Real Estate Taxes for
                the applicable calendar year MULTIPLIED BY the square feet of
                Agreed Rentable Area of the Premises exceeds Landlord's Annual
                Real Estate Taxes Contribution; plus

           (iv) the per square foot Additional Pass Through Costs for the
                applicable calendar year, MULTIPLIED BY the square feet of
                Agreed Rentable Area of the Premises, plus

            (v) Tenant's Share of Variable Operating and Energy Costs Allocable
                to Some Rentable Area (hereinafter defined).

            To arrive at the per square foot Fixed Operating Costs and per
            square foot Fixed Energy Costs, Landlord will divide the applicable
            costs by the Agreed Rentable Area of the Tower. To arrive at the
            per square foot Variable Operating Costs Attributable to All
            Tenants and Variable Energy Costs Attributable to All Tenants,
            Landlord will divide the applicable costs by the average occupied
            rentable area of the Tower for the applicable period.

     (b) At least thirty (30) days prior to January 1 of each calendar year
            during the term of this Lease (or as soon thereafter as is
            reasonably possible), Landlord shall give Tenant written notice of
            Tenant's reasonably estimated Additional Rent (other than Tenant's
            Share of Variable Operating and Energy Costs Allocable to Some
            Rentable Area) for the applicable calendar year and the amount of
            the monthly installment due for each month during such year.

     (c) Tenant shall pay to Landlord on the Commencement Date and on the first
            day of each month thereafter the amount of the applicable monthly
            installment of Additional 


                                       6
<PAGE>   15

            Rent (other than Tenant's Share of Variable Operating and Energy 
            Costs Allocable to Some Rentable Area, which shall be controlled by
            paragraph (d) following).

    (d) Landlord will invoice Tenant monthly for "TENANT'S SHARE OF
            VARIABLE OPERATING AND ENERGY COSTS ALLOCABLE TO SOME RENTABLE
            AREA", which is hereby defined to mean the sum of Tenant's share of
            each Variable Operating Cost and Variable Tower Energy Cost
            incurred at the request of Tenant during the applicable month that
            is attributable both to a portion (but not all) of the Premises and
            to a portion (but not all) of other premises within the Tower.
            Tenant's share of each such Variable Operating Cost and each such
            Variable Tower Energy Cost shall be equal to the applicable costs,
            multiplied by a fraction, the numerator of which shall be the
            Agreed Rentable Area of the Premises to which such cost is
            attributable and the denominator of which shall be the average
            occupied rentable area of the Tower (for the applicable period) to
            which such cost is attributable.

    (e) Within ninety (90) days after the end of each calendar year, or as soon
            thereafter as is reasonably possible, Landlord shall prepare and
            deliver to Tenant a statement showing (i) Tenant's actual
            Additional Rent for the applicable calendar year, and (ii) a
            reasonable breakdown of the component elements in determining such
            Additional Rent. Landlord's obligation to deliver such an annual
            statement for the year during which this Lease expires or is
            terminated shall survive the expiration or earlier termination of
            this Lease. If Tenant's monthly payments of Additional Rent are
            less than Tenant's actual Additional Rent reflected in the
            applicable annual statement, Tenant shall pay the amount of the
            underpayment to Landlord within thirty (30) days after such annual
            statement is furnished to Tenant. If Tenant's total monthly
            payments of Additional Rent for the applicable year are more than
            Tenant's actual Additional Rent reflected in the applicable annual
            statement, then Landlord shall credit against the next Rent payment
            or payments due from Tenant the amount of such overpayment,
            provided, however, with respect to the year in which this Lease
            expires or is terminated, (i) Tenant's Additional Rent shall be
            deemed to be an amount equal to the actual Additional Rent set
            forth in the annual statement for such year, multiplied by a
            fraction, the numerator of which is the number of days occurring
            from and including January 1 of such year and ending on and
            including the date of termination and the denominator of which
            shall be 365, (ii) Landlord shall forward to Tenant the annual
            statement for such year at the same time as Landlord forwards such
            annual statement to tenants of the Building, (iii) Landlord shall
            pay to Tenant the amount of any overpayment of Additional Rent for
            such year (less any amounts Tenant then owes Landlord) within
            thirty (30) days after Landlord delivers the annual statement to
            Tenant, and (iv) Tenant shall pay Landlord the amount of any
            underpayment of Additional Rent for such year within thirty (30)
            days after Tenant receives such annual statement. Unless Tenant
            takes written exception to any item within ninety (90) days after
            the furnishing of an annual statement, such statement shall be
            considered as final and accepted by Tenant.

2.203 BILLING DISPUTES. If there exists any dispute as to (i) the amount
      of Additional Rent, (ii) whether a particular expense is properly
      included in Additional Rent or (iii) Landlord's calculation of Additional
      Rent (each an "ADDITIONAL RENT DISPUTE"), the events, errors, acts 


                                       7
<PAGE>   16

      or omissions giving rise to such Additional Rent Dispute shall not
      constitute a breach or default by Landlord under this Lease and even if a
      judgment resolving the Additional Rent Dispute is entered against
      Landlord, this Lease shall remain in full force and effect and Landlord
      shall not be liable for any consequential damages resulting from the
      event, error, act or omission giving rise to such Additional Rent
      Dispute. Notwithstanding the existence of an Additional Rent Dispute,
      Tenant shall pay timely the amount of Additional Rent which is in dispute
      and will continue to make all subsequent payments of Additional Rent as
      and when required under this Lease, provided that the payment of such
      disputed amount and other amounts shall be without prejudice to Tenant's
      position. If an Additional Rent is resolved in favor of Tenant, Landlord
      shall forthwith pay to Tenant the amount of Tenant's overpayment of
      Additional Rent, together with interest from the time of such overpayment
      at the annual rate of ten percent (10%).

2.204 REVISIONS IN ESTIMATED ADDITIONAL RENT. If Real Estate Taxes,
      Insurance Premiums, Utility Expenses or Additional Pass Through Costs
      increase during a calendar year or if the number of square feet of
      rentable area in the Premises increases, Landlord may revise the
      estimated Additional Rent during such year by giving Tenant written
      notice to that effect and thereafter Tenant shall pay to Landlord, in
      each of the remaining months of such year, an additional amount equal to
      the amount of such increase in the estimated Additional Rent divided by
      the number of months remaining in such year.

      2.205 TENANT'S AUDIT RIGHT. Subject to the remaining terms of this
      subsection, if Landlord does not audit the Operating Expenses and other
      components of Additional Rent for a given calendar year and Tenant timely
      objects to the calculation of the Additional Rent reflected on the
      applicable Annual Statement, Tenant shall have the right, at Tenant's
      sole cost and expense, to perform an annual audit on Landlord's books and
      records which reflect Additional Rent for such year to verify Landlord's
      calculation of actual Additional Rent for such prior year, provided that
      such audit shall be conducted, if at all, (i) within the ninety (90) days
      period following Tenants receipt of the Annual Statement for the
      Additional Rent which Tenant elects to audit, (ii) during Landlord's
      normal business hours, (iii) at the Property or such other place in
      Dallas, Texas where Landlord maintains its records and (iv) only after
      Landlord has received thirty (30) days prior written notice. Tenant shall
      require its auditors to use reasonable efforts to complete its audit
      within thirty (30) days after Landlord makes available its books and
      records reflecting the Additional Rent for the applicable calendar
      year(s). Tenant shall reimburse Landlord for any actual out-of-pocket
      costs incurred by Landlord as result of complying with the requests of
      Tenant's auditor. Tenant shall bear the cost of any audit performed on
      behalf of Tenant pursuant to this subsection. No audit conducted pursuant
      to this paragraph shall be binding on Landlord. If Landlord agrees with
      Tenant's audit and such audit reflects that the Additional Rent reflected
      in the applicable Annual Statement is more than 105% of the Additional
      Rent reflected in Tenant's audit approved by Landlord or if Tenant's
      auditor determines that the Additional Rent reflected in the applicable
      Annual Statement is more than 105% of the actual Additional Rent that
      should have been charged to Tenant for the applicable calendar year and a
      final non-appealable judgment agreeing with Tenant's auditor's
      determination is entered against Landlord, then in either such event
      Landlord will pay the reasonable cost of Tenant's audit.

SECTION 2.3 RENT DEFINED AND NO OFFSETS. Basic Annual Rent, Additional Rent and
all other sums (whether or not expressly designated as rent) required to be
paid to Landlord by Tenant under this Lease (including, without limitation, any
sums payable to Landlord under any addendum, exhibit, rider or schedule
attached hereto) shall constitute rent and are sometimes collectively referred
to as "Rent". Each payment of Rent shall be paid by Tenant when due, without
deduction, setoff or, except as otherwise expressly provided in this Lease,
prior demand.

SECTION 2.4 LATE CHARGES. If any installment of Basic Annual Rent or Additional
Rent or any other payment of Rent under this Lease shall not be paid when due,
a "Late Charge" of five cents ($.05) per dollar so overdue may be charged by
Landlord to defray Landlord's administrative expense incident to the handling
of such overdue payments. Each Late Charge shall be payable on demand.

                          ARTICLE 3--SECURITY DEPOSIT

Tenant will pay Landlord on the date this Lease is executed by Tenant the
Security Deposit set forth in Item 9 of the Basic Lease Provisions as security
for the performance of the terms hereof by Tenant. Tenant shall not be entitled
to interest thereon and Landlord may commingle such Security Deposit with any
other funds of Landlord. The Security Deposit shall not be considered an
advance payment of rental or a measure of Landlord's damages in case of default
by Tenant. If Tenant defaults with respect to any provision of this Lease,
Landlord may, but shall not be required to, from time to time, without
prejudice to any other remedy, use, apply or retain all or any part of this
Security Deposit for the payment of any Rent or any other sum in default or for
the payment of any other amount which Landlord may spend or become obligated to
spend by reason of Tenant's default or to compensate Landlord for any other
loss or damage which Landlord may suffer by reason of Tenant's default,
including, without limitation, costs and reasonable attorneys' fees incurred by
Landlord to recover possession of the Premises. If Tenant shall fully and
faithfully perform every provision of this Lease to be performed by it, the
Security Deposit shall be returned to Tenant within thirty (30) days after the
Expiration Date. Tenant agrees that it will not assign or encumber or attempt
to assign or encumber the monies deposited herein as the Security Deposit and
that Landlord and its successors and assigns shall not be bound by any such
actual or attempted assignment or encumbrance. Regardless of any assignment of
this Lease by Tenant, Landlord may return the Security Deposit to the original
Tenant, in the absence of evidence satisfactory to Landlord of an assignment of
the right to receive the Security Deposit or any part of the balance thereof.

                          ARTICLE 4--OCCUPANCY AND USE

SECTION 4.1 USE OF PREMISES.

4.101 GENERAL. The Premises shall, subject to the remaining provisions of this
      Section, be used solely for the Permitted Use (herein so called)
      specified in Item 11 of the Basic Lease Provisions. Without in any way
      limiting the foregoing, Tenant will not use, occupy or permit the use or
      occupancy of the Premises for any purpose (and the Permitted Use shall
      not include any use) which is forbidden by or in violation of any law,
      ordinance or governmental or municipal regulation, order, or certificate
      of occupancy, or which may be dangerous to life, limb or property; or
      permit the maintenance of any public or private nuisance; or do or permit
      any other thing which may unreasonably disturb the quiet enjoyment of any
      other tenant of the Property; or keep any substance or carry on or permit
      any operation which 

                                       9
<PAGE>   18

      could be reasonably expected to emit offensive odors or conditions from 
      the Premises; or commit or suffer or permit any waste in or upon the
      Premises; or sell, purchase or give away, or permit the sale, purchase or
      gift of food in any form by or to any of Tenant's agents or employees or
      other parties in the Premises except through vending machines in employee
      lunch or rest areas within the Premises for use by Tenant's employees
      only; or use any apparatus which might make undue noise or set up
      vibrations in the Building; or permit anything to be done which would
      increase the fire and extended coverage insurance rate on the Building or
      Building contents and, if there is any increase in such rate by reason of
      acts of Tenant, then Tenant agrees to pay such increase upon demand
      therefor by Landlord. Payment by Tenant of any such rate increase shall
      not be a waiver of Tenant's duty to comply herewith. Tenant shall keep
      the Premises neat and clean at all times.

4.102 HAZARDOUS AND TOXIC MATERIALS.

     (a) For purposes of this Lease, hazardous or toxic materials shall mean
            asbestos containing materials ("ACM") and all other materials,
            substances, wastes and chemicals classified as hazardous or toxic
            substances, materials, wastes or chemicals under then-current
            applicable governmental laws, rules or regulations or that are
            subject to any right-to- know laws or requirements.

     (b) Tenant shall not knowingly incorporate into, or use or otherwise place
            or dispose of any hazardous or toxic materials at or on the
            Premises or the Property except for use and storage of cleaning and
            office supplies used in the ordinary course of Tenant's business
            and then only if (i) such materials are in small quantities,
            properly labeled and contained, (ii) such materials are handled and
            disposed of in accordance with the generally accepted industry
            standards for safety, storage, use and disposal, (iii) notice of
            and a copy of the current material safety data sheet is provided to
            Landlord for each such hazardous or toxic material and (iv) such
            materials are used, transported, stored, handled and disposed of in
            accordance with all applicable governmental laws, rules and
            regulations. Landlord shall have the right to periodically inspect,
            take samples for testing and otherwise investigate the Premises for
            the presence of hazardous or toxic materials. Landlord shall not
            knowingly dispose of any hazardous or toxic materials on the
            Property and shall otherwise deal with all hazardous or toxic
            materials at the Property in a manner that will not materially and
            adversely affect Tenant's access, use or occupancy of the Premises.
            If Landlord or Tenant ever has knowledge of the presence of
            hazardous or toxic materials on the Property that affect the
            Premises, the party having knowledge shall notify the other party
            thereof in writing promptly after obtaining such knowledge.

     (c) If Tenant or its employees, agents or contractors shall ever violate
            the provisions of paragraph (b) of this subsection 4.102 or
            otherwise contaminate the Premises or the Property with hazardous
            or toxic materials, then Tenant shall clean-up, remove and dispose
            of the material causing the violation, in compliance with all
            applicable governmental standards, laws, rules and regulations and
            then prevalent industry practice and standards and shall repair any
            damage to the Premises or Building within such period of time as
            may be reasonable under the circumstances after written notice by
            Landlord. Tenant shall notify Landlord of its method, time and

                                      10
<PAGE>   19

            procedure for any clean-up or removal and Landlord shall have the
            right to require reasonable changes in such method, time or
            procedure or to require the same to be done after normal business
            hours. Tenant's obligations under this subsection 4.102(c) shall
            survive the termination of this Lease. Tenant represents to
            Landlord that, except as has been disclosed to Landlord, Tenant has
            never been cited for or convicted of any hazardous or toxic
            materials violations under applicable laws, rules or regulations.

SECTION 4.2 PERMITS. Tenant shall obtain the certificate of occupancy, if any,
required for occupancy of the Premises following construction of Tenant
Improvements. Tenant shall pay for the cost of any such certificate of
occupancy, provided that Tenant shall be entitled to have such cost funded from
the Finish Allowance, if any, provided for in the Work Letter. If any
governmental license or permit shall be required for the proper and lawful
conduct of Tenant's business in the Premises or any part thereof, Tenant, at
its expense, shall procure and thereafter maintain such license or permit.
Additionally, if Tenant's Improvements or any subsequent alteration or
improvement made to the Premises by Tenant or Tenant's use of the Premises
require any modification or amendment of any certificate of occupancy for the
Building or the issuance of any other permit of any nature whatsoever, Tenant
shall, at its expense, take all actions to procure any such modification or
amendment or additional permit.

SECTION 4.3 COMPLIANCE WITH LAWS.

4.301 TENANT'S COMPLIANCE OBLIGATION.

      (a) Tenant shall comply with all laws, statutes, ordinances, orders,
            permits and regulations (collectively "Laws") affecting (i)

                     ARTICLE 5--UTILITIES AND SERVICES

SECTION 5.1 SERVICES TO BE PROVIDED.

Landlord agrees to furnish or cause to be furnished to the Premises, the
utilities and services described in subsections 5.101 through 5.107 below,
subject to all other provisions of this Lease.

5.101 ELEVATOR SERVICE. Except for Recognized Holidays (as defined in the Rules
      and Regulations) and emergencies, Landlord shall provide during Normal
      Business Hours (as defined in the Rules and Regulations) automatic
      passenger elevator facilities to all floors of the Building and have at
      least one (1) passenger elevator available for use to all floors of the
      Building at all other times (including Recognized Holidays).

5.102 HEAT AND AIR CONDITIONING. Except for Recognized Holidays and
      emergencies, Landlord shall during Normal Business Hours ventilate the
      Premises and furnish heat or air conditioning, at such temperatures and
      in such amounts as is customary in buildings of comparable size, quality
      and in the general vicinity of the Building, with such adjustments as
      Landlord reasonably deems necessary for the comfortable occupancy of the
      Premises, subject to events of force majeure and any governmental
      requirements, ordinances, rules, regulations, guidelines or standards
      relating to, among other things, energy conservation. Upon request and
      provided Tenant is not then in breach of its obligation to pay Rent as
      and when required hereunder, Landlord shall make available, at Tenant's
      expense, after hours heat or air conditioning. The minimum charge and the
      hourly rate for the use of after hours heat or air conditioning shall be
      determined from time to time by Landlord and confirmed in writing to
      Tenant.

5.103 ELECTRICITY.

     (a) Landlord shall furnish to the Premises electric current not in excess
            of that required by the office lighting and receptacles included in
            Tenant's Improvements, provided, however, Tenant shall be solely
            responsible for the costs of electrical consumption (without
            duplication) (i) by equipment which requires a voltage other than
            120 volts single phase, (ii) in excess of that currently supplied
            to the Premises or (iii) by any single piece of equipment in excess
            of 0.5 kilowatts at rated capacity (any such consumption, "EXCESS
            CONSUMPTION" and the costs of such Excess Consumption, "EXCESS
            CONSUMPTION COSTS").

     (b) Landlord may, from time to time, engage a reputable consultant to
            conduct a survey of electrical usage within the Premises or install
            one or more submeters to measure electrical usage within the
            Premises or a particular floor of the Premises. If the survey or
            submeters reflect Excess Consumption, then (i) Tenant shall be
            responsible for the costs of any such surveys and submeters, (ii)
            Landlord shall have the right to install permanent submeters to
            measure the electrical consumption within the Premises (which
            permanent submeters shall constitute a part of Tenant's Submeters,
            as hereinafter defined), and (iii) Tenant shall pay for the cost of
            acquiring, maintaining, repairing and reading such submeters.

     (c) Tenant shall not (i) without the express prior written consent of
            Landlord (which consent shall not be unreasonably withheld) install
            or use or permit the installation or use of 


                                      13
<PAGE>   22

            any computer or electronic data processing equipment or any other
            electrical equipment which (singly) consumes more than 0.5
            kilowatts at rated capacity or requires a voltage other than 120
            volts single phase or otherwise has high electrical consumption,
            (ii) use electric current in excess of the capacity of the feeders
            or lines to the Building or the risers or wiring installation of
            the Building or the Premises, or (iii) without the prior written
            consent of Landlord (which consent shall not be unreasonably
            withheld) install any electrical plugs, connections or outlets
            which supply a voltage greater than 120 volts single phase. As a
            condition to obtaining Landlord's consent to any equipment
            described in clause (i) or any plugs, connections or outlets
            described in clause (iii), Tenant shall arrange for the
            installation of a permanent submeter (all submeters installed as
            part of or in connection with Tenant's Improvements or
            Installations or pursuant to this paragraph are herein collectively
            referred to as "TENANT'S SUBMETERS"), at Tenant's expense, to
            measure the electrical power consumed by the equipment and/or
            machinery hooked or plugged into such plugs, connections or
            outlets. Without in any way limiting the meaning of reasonable,
            Landlord shall be deemed to have reasonably withheld its consent to
            the matters described in clauses (i) and (ii) if the installation
            of the applicable equipment or the use of the plugs, outlets or
            connections could, in Landlord's judgment, interfere with
            Landlord's ability to provide Building standard electricity to any
            other tenant of the Building or Landlord's ability to fulfill any
            of its obligations under any other lease.

     (d) On or about the first day of each month thereafter during the Term of
            this Lease, Landlord will, at Tenant's cost, read Tenant's
            Submeters and record such readings for purposes of determining
            Metered Electrical Expenses pursuant to paragraph (e) immediately
            following. Landlord will maintain and repair Tenant's Submeters, at
            Tenant's cost.

     (e) The cost of electricity consumed within each separately metered
            portion of the Premises and by each separately metered piece of
            equipment within the Premises ("METERED ELECTRICAL EXPENSES") shall
            be equal to the sum of (i) the kilowatts of electricity consumed
            within the separately metered portions of the Premises (as measured
            by the applicable Tenant's Submeters) during the applicable month
            (or other applicable period) and (ii) the kilowatts of electricity
            consumed by each separately metered equipment within the Premises
            (as measured by the applicable Tenant's Submeters), MULTIPLIED BY
            (iii) the cost per kilowatt of electricity charged to Landlord by
            the public utility for electricity consumed within the Building
            during the applicable month (or other applicable period). Landlord
            may, from time to time, invoice Tenant for Metered Electrical
            Expenses (as well as any Excess Consumption Costs determined by a
            reputable consultant) and Tenant shall, within ten (10) days after
            receiving an invoice therefor, pay Landlord the amount of the
            Metered Electrical Expenses (and/or, as applicable, any Excess
            Consumption Costs determined by a reputable consultant) covered by
            such invoice. Each such invoice submitted by Landlord to Tenant
            shall include (i) the period of consumption covered by such
            invoice, (ii) the beginning and ending readings for each of
            Tenant's Submeters for such period, (iii) Landlords calculation of
            the Metered Electrical Expenses covered


                                      14
<PAGE>   23



            by such invoice, and (iv) if applicable, the independent electrical
            consultant's calculation of Excess Consumption and the Excess
            Consumption Costs.

5.104 WATER. Landlord shall furnish water for drinking, cleaning and lavatory 
      purposes only.

5.105 JANITORIAL SERVICES. Landlord shall provide janitorial services to the
      Premises, comparable to that provided in other office buildings of
      similar size, quality and in the general vicinity of the Building,
      provided the Premises are used exclusively as offices and further
      provided Tenant complies with subsection 6.201 below.

5.106 COMMON AREAS. Landlord shall perform routine maintenance in the Common
      Areas (hereinafter defined) and otherwise maintain the Common Areas in a
      state of repair that is comparable to that provided in other comparable
      buildings in the general vicinity of the portion of the Dallas Central
      Business District in which the Building is located, but in no event will
      the foregoing standard be interpreted to require Landlord to perform
      renovations of or make capital improvements to the Common Areas (other
      than those in the nature of repairs).

5.107 BULBS AND BALLASTS. Landlord shall provide Building standard bulbs and
      ballasts as necessary in the Premises. Landlord shall also provide
      non-building standard bulbs and ballasts provided Tenant shall pay the
      cost thereof, together with an administrative fee equal to ten percent
      (10%) of such cost. All amounts due under this subsection for such
      non-building standard bulbs shall be paid to Landlord within thirty (30)
      days after receipt of an invoice therefor.

5.108 SECURITY GUARD AND ACCESS SYSTEM. Landlord shall provide Building
      standard security to the Property on a 24-hour basis on all days of the
      year, which security may include limited access entry cards to the
      Building and Parking Facilities and security personnel in stationary
      locations or in mobile patrols. Tenant acknowledges that the security
      services to be provided by Landlord hereunder are not a guaranty or a
      representation of the safety of Tenant or Tenant's employees, invitees,
      guests or any other person or of any property, or that the Property is
      secure.

SECTION 5.2 ADDITIONAL SERVICES. Landlord may impose a reasonable charge for
any utilities and services, including without limitation, air conditioning,
electrical current and water, provided by Landlord by reason of any use of the
services at any time other than the hours set forth in subsection 5.102 above
or beyond the levels or quantities that Landlord agrees herein to furnish or
because of special electrical, cooling or ventilating needs created by Tenant's
hybrid telephone equipment, computers or other equipment. In no event will
Landlord be required to provide any additional services if Tenant is in breach
of its obligation to pay any Rent hereunder as and when due and payable.

SECTION 5.3 TENANT'S OBLIGATION. Tenant agrees to cooperate fully at all times
with Landlord and to abide by all regulations and requirements which Landlord
reasonably prescribes for the use of the above utilities and services.

      LANDLORD'S FAILURE TO MAINTAIN TEMPERATURE OR ELECTRICAL CONSTANCY LEVELS
      OR TO FURNISH ANY OF THE FOREGOING SERVICES when such failure is caused
      by accident, breakage, repairs, strikes, lockouts or other labor
      disturbance or labor dispute of any character, governmental regulation,
      moratorium or other governmental action, inability to obtain electricity,
      water or fuel, or by any cause beyond Landlord's reasonable control
      (collectively, "UNCONTROLLABLE EVENTS"), NOR SHALL ANY SUCH
      UNCONTROLLABLE EVENT OR RESULTS OR EFFECTS THEREOF BE CONSTRUED AS AN
      EVICTION (CONSTRUCTIVE OF ACTUAL) OF TENANT OR AS A BREACH OF THE IMPLIED
      WARRANTY OF SUITABILITY, OR RELIEVE TENANT FROM THE OBLIGATION TO PERFORM
      ANY COVENANT OR AGREEMENT HEREIN AND IN NO EVENT SHALL LANDLORD BE LIABLE
      FOR DAMAGE TO PERSONS OR PROPERTY (INCLUDING, WITHOUT LIMITATION,
      BUSINESS INTERRUPTION) OR BE IN DEFAULT HEREUNDER, AS A RESULT OF ANY
      SUCH UNCONTROLLABLE EVENT OR RESULTS OR EFFECTS THEREOF.

5.402 LIMITED RIGHT TO ABATEMENT OF RENT. If any portion of the Premises
      becomes unfit for occupancy and Tenant vacates such portion of the
      Premises because Landlord fails to deliver any service as required under
      Section 5.1 above for any period (other than a reconstruction period
      conducted pursuant to Section 7.1 or Article 8 below) exceeding ten (10)
      consecutive days after written notice by Tenant to Landlord and provided
      such failure is not caused by Tenant, Tenant's Contractors or any of
      their respective agents or employees, Tenant shall be entitled to a fair
      partial abatement of Basic Annual Rent and Additional Rent for any such
      portion of the Premises from the expiration of such ten (10) day period

      than Tenant's Improvements under the Work Letter) to, or install any
      equipment or machinery (other than office equipment and unattached
      personal property) on, the Premises (all such changes, modifications,
      alterations, additions, improvements (other than Tenant's Improvements
      under the Work Letter) and installations approved by Landlord are herein
      collectively referred to as "INSTALLATIONS") if any such Installations
      would (i) affect any structural or load bearing portions of the Building,
      (ii) result in a material increase of electrical usage above the normal
      type and amount of electrical current to be provided by Landlord, (iii)
      result in an increase in Tenant's usage of heating or air conditioning,
      (iv) impact mechanical, electrical or plumbing systems in the Premises or

      which consent shall not be unreasonably withheld or delayed. All
      Installations shall be at Tenant's sole cost and expense. Without in any
      way limiting Landlord's consent rights, Landlord shall not be required to
      give its consent until (a) Landlord approves the contractor or person
      making such Installations and approves such contractor's insurance
      coverage to be provided in connection with the work, (b) if plans and
      specifications are reasonably required for the performance of the
      applicable work, Landlord

                                      18
<PAGE>   27


      approves final and complete plans and specifications for such work and
      (c) the appropriate governmental agency, if any, has approved the plans
      and specifications for such work. All work performed by Tenant or its
      contractor relating to the Installations shall conform to applicable
      governmental laws, rules and regulations, including, without limitation,
      the Disability Acts. Upon completion of the Installations for which plans
      and specifications are required, Tenant shall deliver to Landlord "as
      built" plans. If Landlord performs such Installations, Tenant shall pay
      Landlord, as additional Rent, the cost thereof plus ten percent (10%) as
      reimbursement for Landlord's overhead. Each payment shall be made to
      Landlord within thirty (30) days after receipt of an invoice from
      Landlord. All Installations (other than Tenant's trade fixtures) that
      constitute improvements constructed within the Premises shall be

      this Lease, unless Landlord requests that same be removed pursuant to
      Section 1.3 above. Tenant shall indemnify and hold Landlord harmless
      from, and reimburse Landlord for and with respect to, any and all costs,
      expenses (including reasonable attorneys' fees), demands, claims, causes
      of action and liens arising from or in connection with any Installations
      performed by or on behalf of Tenant.. All Installations performed by or
      on behalf of Tenant will be performed diligently and in a first-class
      workmanlike manner and in compliance with all applicable laws,
      ordinances, regulations and rules of any public authority having
      jurisdiction over the Building and/or Tenant's and Landlord's insurance
      carriers. Landlord will have the right, but not the obligation, to
      inspect periodically the work on the Premises and may require reasonable
      changes in the method or quality of the work.

6.304 APPROVALS. Any approval by Landlord (or Landlord's architect and/or
      engineers) of any of Tenant's contractors or Tenant's drawings, plans or
      specifications which are prepared in connection with any construction of
      improvements (including without limitation, Tenant's Improvements) in the
      Premises shall not in any way be construed as or constitute a
      representation or warranty of Landlord as to the abilities of the
      contractor or the adequacy or sufficiency of such drawings, plans or
      specifications or the improvements to which they relate, for any use,
      purpose or condition.

                    ARTICLE 7--INSURANCE, FIRE AND CASUALTY

SECTION 7.1 TOTAL OR PARTIAL DESTRUCTION OF THE BUILDING OR THE PREMISES. In
the event that the Building should be totally destroyed by fire or other
casualty or in the event the Building (or any portion thereof) should be so
damaged that rebuilding or repairs cannot be completed, in Landlord's
reasonable opinion, within one hundred eighty (180) days after commencement of
repairs to the Building, Landlord may, at its option, terminate this Lease, in
which event Basic Annual Rent and Additional Rent shall be abated during the
unexpired portion of this Lease effective with the date of such damage.
Landlord shall exercise the termination right pursuant to the preceding
sentence, if at all, by delivering written notice of 


                                      17
<PAGE>   28

termination to Tenant within ten (10) days after determining that the repairs
cannot be completed within such one hundred eighty (180) day period. In the
event that the Premises should be so damaged by fire or other casualty that
rebuilding or repairs cannot be completed, in Landlord's reasonable opinion,
within one hundred eighty (180) days after the commencement of repairs to the
Premises, Tenant may, at its option terminate this Lease, in which event Basic
Annual Rent and Additional Rent shall be abated during the unexpired portion of
this Lease, effective the date of termination. Tenant shall exercise the
termination right pursuant to the preceding sentence, if at all, by delivering
written notice of termination to Landlord within ten (10) days after being
advised by Landlord that the repairs cannot be completed within such one
hundred eighty (180) day period. In the event the Building or the Premises
should be damaged by fire or other casualty and, in Landlord's reasonable
opinion, the rebuilding or repairs can be completed within one hundred eighty
(180) days after the commencement of repairs to the Building or Premises, as
applicable, or if the damage should be more serious but neither Landlord nor
Tenant elect to terminate this Lease pursuant to this Section, in either such
event Landlord shall, within sixty (60) days after the date of such damage,
commence (and thereafter pursue with reasonable diligence) repairing the
Building and the Premises (including Tenant's Improvements), but only to the
extent of insurance proceeds actually received by Landlord for such repairs, to
substantially the same condition which existed immediately prior to the
happening of the casualty. In no event shall Landlord be required to rebuild,
repair or replace any part of the furniture, equipment, fixtures, inventory,
supplies or any other personalty or any other improvements (except Tenant's
Improvements to the extent set forth in the preceding sentence), which may have
been placed by Tenant within the Building or at the Premises. Landlord shall
allow Tenant a fair diminution of Basic Annual Rent and Additional Rent during
the time the Premises are unfit for the conduct of Tenant's business; provided,
that if such casualty was caused primarily by Tenant, its agents, employees,
licensees, contractors or invitees, Basic Annual Rent and Additional Rent shall
be abated only to the extent Landlord is compensated for such Basic Annual Rent
and Additional Rent by loss of rents insurance, if any. Notwithstanding
Landlord's restoration obligation, in the event any mortgagee under a deed of
trust, security agreement or mortgage on the Building should require that the
insurance proceeds be used to retire or reduce the mortgage debt or if the
insurance company issuing Landlord's fire and casualty insurance policy fails
or refuses to pay Landlord the proceeds under such policy, Landlord shall have
no obligation to rebuild and this Lease shall terminate upon notice by Landlord
to Tenant. Subject to the provisions of subsection 7.201(c) below, any
insurance which may be carried by Landlord or Tenant against loss or damage to
the Building or to the Premises shall be for the sole benefit of the party
carrying such insurance and under its sole control.

SECTION 7.2 TENANT'S INSURANCE.

7.201 TYPES OF COVERAGE. Tenant covenants and agrees that from and after the
      date which is ten (10) days prior to Tenant's occupancy of the Premises,
      Tenant will carry and maintain, at its sole cost and expense, the
      insurance set forth in paragraphs (a), (b) and (c) of this subsection.

     (a) Commercial General Liability Insurance covering the Premises and
            Tenant's use thereof against claims for personal or bodily injury
            or death or property damage occurring upon, in or about the
            Premises (including contractual indemnity and liability coverage),
            such insurance to insure both Tenant and, as additional named
            insureds, Landlord and the Property Manager, and to afford
            protection to the limit of not less than $2,000,000.00, combined
            single limit, in respect to injury or death to any number of
            persons and all property damage arising out of any one (1)
            occurrence, with a deductible acceptable to Landlord. This
            insurance coverage shall (i) extend to any liability of Tenant
            arising out of the indemnities provided for in this Lease and (ii)
            be issued on an "occurrence" basis, as opposed to a "claims made"
            basis.

     (b) Property insurance on an all-risk basis (including, without
            limitation, coverage against fire, wind, tornado, vandalism,
            malicious mischief, water damage and sprinkler

            in the Premises and endorsed to provide one hundred percent (100%)
            replacement cost coverage. Such policy will be written in the names
            of Tenant, Landlord and any other parties reasonably designated by
            Landlord from time to time, as their respective interests may
            appear. The property insurance may, with the consent of the
            Landlord, provide for a reasonable deductible.

     (c) Worker's compensation insurance insuring against and satisfying
            Tenant's obligations and liabilities under the worker's
            compensation laws of the State of Texas, together with employer's
            liability insurance in an amount not less than $1,000,000.00.

7.202 OTHER REQUIREMENTS OF INSURANCE. All such insurance will be issued and
      underwritten by companies reasonably acceptable to Landlord and will
      contain endorsements that (a) such insurance may not lapse with respect
      to Landlord or Property Manager or be canceled or amended with respect to
      Landlord or Property Manager without the insurance company giving
      Landlord and Property Manager at least thirty (30) days prior written
      notice of such cancellation or amendment, (b) Tenant will be solely
      responsible for payment of premiums, (c) in the event of payment of any
      loss covered by such policy, Landlord or Landlord's designees will be
      paid first by the insurance company for Landlord's loss and (d) Tenant's
      insurance is primary in the event of overlapping coverage which may be
      carried by Landlord.

7.203 PROOF OF INSURANCE. Tenant shall deliver to Landlord duplicate originals
      of all policies of insurance required by this Section 7.2 or duly
      executed originals of the evidence of such insurance (on ACORD form 27 or
      a similar form) evidencing in-force coverage, stating that Landlord is an
      additional insured thereunder, agreeing to give Landlord at least thirty
      (30) days written notice prior to termination, cancellation or any
      modification adversely affecting Landlord within ten (10) days before
      Tenant's occupancy of the Premises and providing such other information
      as is required by subsection 7.202 above. Further, Tenant shall deliver
      to Landlord renewals thereof at least thirty (30) days prior to the
      expiration of the respective policy terms.

SECTION 7.3 LANDLORD'S INSURANCE.

7.301 TYPES OF COVERAGE. Landlord covenants and agrees that from and after the
      date of delivery of the Premises from Landlord to Tenant, Landlord will
      carry and maintain, at its sole cost and expense, the insurance set forth
      in paragraphs (a) and (b) of this subsection.

      (a) Commercial General Liability Insurance covering the Building and all
      Common Areas, but excluding the Premises, insuring against claims for
      personal or bodily injury or death or property damage occurring upon, in
      or about the Building or Common Areas to afford protection to the limit
      of not less than $2,000,000.00 combined single limit in respect to injury
      or death to any number of persons and property damage arising out of any
      one (1) occurrence. This insurance coverage shall extend to any liability
      of Landlord arising out of the indemnities provided for in this Lease.

      (b) Landlord shall at all times during the term hereof maintain in effect
      a policy or policies of all risk extended coverage insurance covering the
      Building (excluding property required 


                                      21

<PAGE>   30

      to be insured by Tenant) endorsed to provide full replacement cost
      coverage and providing protection against perils included within the
      standard Texas form of fire and extended coverage insurance policy,
      together with insurance against sprinkler damage, vandalism, malicious
      mischief and such other risks as Landlord may from time to time determine
      and with any such deductibles as Landlord may from time to time
      determine.

7.302 SELF INSURANCE AND BLANKET INSURANCE. Any insurance provided for in
      subsection 7.301 above may be effected by self-insurance or by a policy
      or policies of blanket insurance covering additional items or locations
      or assureds, provided that the requirements of this Section 7.3 are
      otherwise satisfied. Tenant shall have no rights in any policy or
      policies maintained by Landlord.

SECTION 7.4 WAIVER OF SUBROGATION. Landlord and Tenant each hereby waives any
rights it may have against the other (including, but not limited to, a direct
action for damages) on account of any loss or damage occasioned to Landlord or
Tenant, as the case may be (EVEN IF (X) SUCH LOSS OR DAMAGE (A) IS CAUSED BY
THE FAULT, NEGLIGENCE OR OTHER TORTIOUS CONDUCT, ACTS OR OMISSIONS OF THE
RELEASED PARTY OR THE RELEASED PARTY'S DIRECTORS, EMPLOYEES, AGENTS OR INVITEES
AND/OR (B) THE RELEASED PARTY IS STRICTLY LIABLE FOR SUCH LOSS OR DAMAGE), to
their respective property, the Premises, its contents or to any other portion
of the Building or the Property arising from any risk (without regard to the
amount of coverage or the amount of deductible) covered by the property
insurance required to be carried by Tenant and Landlord, respectively, under
subsections 7.201(b) and 7.301(b) above. The foregoing waiver shall be
effective even if either or both parties fail to carry the property insurance
required by Sections 7.201(b) and 7.301(b) above. If a party waiving rights
under this Section is carrying an all risk property insurance policy in the
promulgated form used in the State of Texas and an amendment to such
promulgated form is passed, such amendment shall be deemed not a part of such
promulgated form until it applies to the policy being carried by the waiving
party. Without in any way limiting the foregoing waivers and to the extent
permitted by applicable law, the parties hereto each, on behalf of their
respective insurance companies insuring the property of either Landlord or
Tenant against any such loss, waive any right of subrogation that Landlord or
Tenant or their respective insurers may have against the other party or their
respective officers, directors, employees, agents or invitees and all rights of
their respective insurance companies based upon an assignment from its insured.
Each party to this Lease agrees immediately to give to each such insurance
company written notification of the terms of the mutual waivers contained in
this Section and to have said insurance policies properly endorsed, if
necessary, to prevent the invalidation of said insurance coverage by reason of
said waivers. The foregoing waiver shall be effective whether or not the
parties maintain the required insurance.

SECTION 7.5 INDEMNITY.

7.501 TENANT'S INDEMNITY. Subject to the limitation and exclusions set forth
      below in this subsection, Tenant will indemnify and hold harmless
      Landlord, Property Manager, their respective officers, directors, and
      employees and any other parties for whom Landlord and/or Property Manager
      are legally responsible (each a "LANDLORD INDEMNIFIED PARTY") from, and
      shall reimburse each Landlord Indemnified Party for and with respect to,
      any and all costs, expenses (including, without limitation, reasonable
      attorneys fees), claims, demands, actions, proceedings, judgments,
      hearings, damages, losses and liabilities brought or asserted by or
      

                                      22

<PAGE>   31

      payable to any third party on account of personal injury, death, property
      damage or any other form of injury or damage (each a "CLAIM" and
      collectively the "CLAIMS") arising out of or relating to (a) an incident
      or event which occurred within or on the Premises, EVEN IF THE (X)
      INCIDENT OR EVENT IS THE RESULT OF OR CAUSED BY THE NEGLIGENT ACTS OR
      OMISSIONS OF ANY LANDLORD INDEMNIFIED PARTY OR (Y) THE LANDLORD
      INDEMNIFIED PARTY IS STRICTLY LIABLE FOR ANY CLAIM ARISING FROM SUCH
      INCIDENT OR EVENT, (b) the use or occupancy of the Premises, EVEN IF (X)
      THE CLAIM IS THE RESULT OF OR CAUSED BY THE NEGLIGENT ACTS OR OMISSIONS
      OF ANY LANDLORD INDEMNIFIED PARTY OR (Y) THE LANDLORD INDEMNIFIED PARTY
      IS STRICTLY LIABLE FOR SUCH CLAIM, or (c) any breach of this Lease by
      Tenant and which resulted in a Claim. The indemnification and
      reimbursement obligations of Tenant under this subsection (i) shall be
      limited to the greater of the amount of Commercial General Liability
      Insurance required to be carried by Tenant under this Lease or $5,000,000
      and (ii) shall not apply to a Claim (a) waived by Landlord under Section
      7.4 above or any other provision of this Lease, (b) related to hazardous
      or toxic materials and caused by an act or omission that does not
      constitute a breach by Tenant of the provisions of subsection 4.102 above
      or EXHIBIT H attached hereto, (c) arising out of the gross negligence or
      intentional misconduct of the Landlord Indemnified Party or (d) resulting
      from host liquor liability. If a third party files a lawsuit or brings
      any other legal action asserting a Claim against a Landlord Indemnified
      Party and that is covered by Tenant's indemnity, then Tenant, upon notice
      from the Landlord Indemnified Party, shall resist and defend such Claim
      through counsel reasonably satisfactory to the Landlord Indemnified
      Party. Tenant's obligations under this subsection shall survive the
      termination of this Lease.

7.502 LANDLORD'S INDEMNITY. Subject to the limitation and exclusions set forth
      below in this subsection, Landlord will indemnify and hold harmless
      Tenant and its officers, directors, and employees and any other parties
      for whom Tenant is legally responsible (each a "TENANT INDEMNIFIED
      PARTY") from, and shall reimburse each Tenant Indemnified Party for and
      with respect to, any and all Claims (as defined in subsection 7.501
      preceding) arising out of or relating to (a) an incident or event which
      occurred within or on the Common Areas, EVEN IF THE (X) INCIDENT OR EVENT
      IS THE RESULT OF OR CAUSED BY THE NEGLIGENT ACTS OR OMISSIONS OF ANY
      TENANT INDEMNIFIED PARTY OR (Y) THE TENANT INDEMNIFIED PARTY IS STRICTLY
      LIABLE FOR ANY CLAIM ARISING FROM SUCH INCIDENT OR EVENT, (b) the use of
      the Common Areas, EVEN IF (X) THE CLAIM IS THE RESULT OF OR CAUSED BY THE
      NEGLIGENT ACTS OR OMISSIONS OF ANY TENANT INDEMNIFIED PARTY OR (Y) THE
      TENANT INDEMNIFIED PARTY IS STRICTLY LIABLE FOR SUCH CLAIM, or (c) any
      breach of this Lease by Landlord and which resulted in a Claim. The
      indemnification and reimbursement obligations of Landlord under this
      subsection (i) shall be limited to the greater of the amount of
      Commercial General Liability Insurance required to be carried by Landlord
      under this Lease or $5,000,000 and (ii) shall not apply to a Claim (a)
      waived by Tenant under Section 7.4 above or any other provision of this
      Lease, (b) related to hazardous or toxic materials and caused by an act
      or omission that does not constitute a breach by Landlord of the
      provisions of subsection 4.102 above or EXHIBIT H attached hereto, (c)
      arising out of the gross negligence or intentional misconduct of the
      Tenant Indemnified Party or (d) resulting from host liquor liability. If
      a third party files a 


                                      23

<PAGE>   32

      lawsuit or brings any other legal action asserting a Claim against a 
      Tenant indemnified Party and that is covered by Landlord's indemnity, then
      Landlord, upon notice from the Tenant Indemnified Party, shall resist and
      defend such Claim through counsel reasonably satisfactory to the Tenant
      Indemnified Party. Landlord's obligations under this subsection shall
      survive the termination of this Lease.

                            ARTICLE 8--CONDEMNATION

SECTION 8.1 CONDEMNATION--CONTINUED USE NOT FEASIBLE. If the Property or any
portion thereof that, in Landlord's reasonable opinion, is necessary to the
continued efficient and/or economically feasible use of the Property shall be
taken or condemned in whole or in part for public purposes, or sold to a
condemning authority in lieu of taking, then the term of this Lease shall, at
the option of Landlord, forthwith cease and terminate.

SECTION 8.2 TOTAL CONDEMNATION OF PREMISES. In the event that all or
substantially all of the Premises is taken or condemned or sold in lieu thereof
or Tenant will be unable to use a substantial portion of the Premises for a
period of one hundred eighty (180) consecutive days by reason of a temporary
taking, either Landlord or Tenant may terminate this Lease by delivering
written notice thereof to the other within ten (10) business days after the
taking, condemnation or sale in lieu thereof.

SECTION 8.3 CONDEMNATION WITHOUT TERMINATION. If upon a taking or condemnation
or sale in lieu of the taking of all or less than all of the Property which
gives either Landlord or Tenant the right to terminate this Lease pursuant to
Section 8.1 or 8.2 above and neither Landlord nor Tenant elect to exercise such
termination right, then this Lease shall continue in full force and effect,
provided that, if the taking, condemnation or sale includes any portion of the
Premises, the Basic Annual Rent and Additional Rent shall be redetermined on
the basis of the remaining square feet of Agreed Rentable Area of the Premises.
Landlord, at Landlord's sole option and expense, shall restore and reconstruct
the Building to substantially its former condition to the extent that the same
may be reasonably feasible, but such work shall not be required to exceed the
scope of the work done by Landlord in originally constructing the Building, nor
shall Landlord in any event be required to spend for such work an amount in
excess of the amount received by Landlord as compensation or damages (over and
above amounts going to the mortgagee of the property taken) for the part of the
Building or the Premises so taken.

SECTION 8.4 CONDEMNATION PROCEEDS. Landlord shall receive the entire award
(which shall include sales proceeds) payable as a result of a condemnation,
taking or sale in lieu thereof. Tenant hereby expressly assigns to Landlord any
and all right, title and interest of Tenant now or hereafter arising in and to
any such award. Tenant shall, however, have the right to recover from such
authority through a separate award which does not reduce Landlord's award, any
compensation as may be awarded to Tenant on account of moving and relocation
expenses and depreciation to and removal of Tenant's physical property.

                                ARTICLE 9--LIENS

Tenant shall keep the Premises and the Property free from all liens arising out
of any work performed, materials furnished or obligations incurred by or for
Tenant and Tenant shall indemnify


                                      24
<PAGE>   33

and hold harmless Landlord from and against, and reimburse Landlord for and
with respect to, any and all Claims, arising from or in connection with any
such liens. In the event that Tenant shall not, within ten (10) days following
written notification from Landlord to Tenant of the imposition of any such
lien, cause the same to be released of record by payment or the posting of a
bond in amount, form and substance acceptable to Landlord, Landlord shall have,
in addition to all other remedies provided herein and by law, the right but not
the obligation, to cause the same to be released by such means as it shall deem
proper, including payment of or defense against the claim giving rise to such
lien. All amounts paid or incurred by Landlord in connection therewith shall be
paid by Tenant to Landlord on demand and shall bear interest from the date of
demand until paid at the rate set forth in Section 15.10 below. Nothing in this
Lease shall be deemed or construed in any way as constituting the consent or
request of Landlord, express or implied, by inference or otherwise, to any
contractor, subcontractor, laborer or materialman for the performance of any
labor or the furnishing of any materials for any specific improvement,
alteration or repair of or to the Building or the Premises or any part thereof,
nor as giving Tenant any right, power or authority to contract for or permit
the rendering of any services or the furnishing of any materials that would
give rise to the filing of any mechanic's or other liens against the interest
of Landlord in the Property or the Premises.

                     ARTICLE 10--TAXES ON TENANT'S PROPERTY

Tenant shall be liable for and shall pay, prior to their becoming delinquent,
any and all taxes and assessments levied against, and any increases in Real
Estate Taxes as a result of, any personal property or trade or other fixtures
placed by Tenant in or about the Premises. In the event Landlord pays any such
additional taxes or increases, Tenant will, within thirty (30) days after
demand, reimburse Landlord for the amount thereof. Without in any way limiting
the foregoing provisions, if any authority levying real and personal property
taxes against the Tower as a standard practice for determining the value of the
Tower for tax purposes includes a component for tenant improvements or
non-movable trade fixtures of individual tenants, Tenant will pay Landlord any
portion of such taxes which is equal to the product of (i) the total of such
taxes multiplied by (ii) the fraction the numerator of which is the cost of
tenant improvements or non-movable trade fixtures in the Premises in excess of
the Building standard or existing improvements (collectively, "ABOVE STANDARD
IMPROVEMENTS") and the denominator of which is the cost of all tenant
improvements in the Tower. Upon receipt of any such tax statement, Landlord
will compute Tenant's share of taxes attributable to Above Standard
Improvements, and submit a statement to Tenant evidencing the method of
calculation. Tenant will pay to Landlord together with the next monthly
installment of Base Annual Rent due after the receipt of Landlord's statement
the entire amount due under this Article. The method of calculation of the
share of taxes attributable to Above Standard Improvements will be subject to
adjustment by Landlord from time to time in order to reflect the method
currently utilized by taxing authorities to calculate taxes for Above Standard
Improvements. If Tenant is assessed for taxes for Above Standard Improvements
directly by the taxing authorities, Tenant will pay the same before delinquency
and deliver to Landlord copies of receipts for payment of such taxes and
assessments no later than ten (10) days prior to the deadline for payment
without imposition of penalty.

                      ARTICLE 11--SUBLETTING AND ASSIGNING

SECTION 11.1 SUBLEASE AND ASSIGNMENT.

11.101 GENERAL PROHIBITION ON ASSIGNMENT AND SUBLEASING. Except as permitted by
       subsection 11.102, Tenant shall not assign this Lease, or allow it to be
       assigned, in whole or in part, by operation of law or otherwise (it
       being agreed that for purposes of this Lease, assignment shall include,
       without limitation, the transfer of a majority interest of stock,
       partnership or other forms of ownership interests, merger or
       dissolution) or mortgage or pledge the same, or sublet the Premises or
       any part thereof or permit the Premises to be occupied by any firm,
       person, partnership or corporation or any combination thereof, other
       than Tenant, without the prior written consent of Landlord.
       Notwithstanding any subletting or assignment by Tenant hereunder or any
       provision herein to the contrary, Tenant shall remain fully liable for
       the performance of all the covenants, agreements, terms, provisions and
       conditions contained in this Lease on the part of Tenant to be
       performed, including without limitation, Tenant's obligation to pay
       Basic Rent and Additional Rent during the entire Term. Tenant shall
       deliver to Landlord a copy of each assignment or sublease entered into
       by Tenant promptly after the execution thereof, whether or not
       Landlord's consent is required in connection therewith. No assignee or
       sublessee of the Premises or any portion thereof may assign or sublet
       the Premises or any portion thereof. Consent by Landlord to one or more
       assignments or sublettings shall not operate as a waiver of Landlord's
       rights as to any subsequent assignments and/or sublettings. Any
       assignment made by Tenant shall be in recordable form and shall contain
       a covenant of assumption by the assignee running to Landlord. All
       reasonable legal fees and expenses incurred by Landlord in connection
       with any assignment or sublease proposed by Tenant will be the
       responsibility of Tenant and will be paid by Tenant within thirty (30)
       days of receipt of an invoice from Landlord.

11.102 ASSIGNMENT TO AFFILIATE AND PERMITTED OFFERINGS.

       (a) Notwithstanding the prohibition against assignment and subleasing
              contained in subsection 11.101, Tenant may, without the prior
              written consent of Landlord, but only after giving Landlord at
              least thirty (30) days prior written notice (which notice shall
              include the identity of the Affiliate [hereinafter defined], the
              relationship of the Affiliate to Tenant and the form of the
              proposed assignment or sublease, which shall be in form
              reasonably satisfactory to Landlord), sublet the Premises or any
              part thereof to an Affiliate or assign this Lease to an Affiliate
              or permit occupancy of any portion of the Premises by an
              Affiliate. The term "Affiliate" shall mean (i) any corporation
              which, directly or indirectly, controls or is controlled by or is
              under common control with Tenant or (ii) any corporation not less
              than fifty percent (50%) of whose outstanding stock shall, at the
              time, be owned directly or indirectly by Tenant or Tenant's
              parent corporation, or (iii) any entity which merges with Tenant
              or a new entity which results from a merger between Tenant and
              another entity, provided such merged entity or new resulting
              entity has a financial net worth at least equal to the greater of
              (a) the net worth of Tenant on the date of this Lease or (b) the
              net worth of Tenant immediately prior to the merger. For purposes
              of this subsection (b), "control" shall mean the possession,
              directly or indirectly, of the power to direct or cause the
              direction of the management and policies of such corporation,
              whether

            through the ownership of voting securities or by contract or 
            otherwise and ownership of the liabilities, losses, profits and 
            tax benefits for such entity.

     (b) Notwithstanding any provision or inference in this Lease to the
            contrary, Tenant may issue new stock in connection with any public
            offering or private placement of such stock.                      

SECTION 11.2 LANDLORD'S RIGHTS.

11.201 LANDLORD'S TERMINATION AND CONSENT RIGHTS.

     (a) If Tenant desires to assign any portion of this Lease or sublease
            any portion of the Premises to any party other than an Affiliate,
            Tenant shall submit to Landlord (a) in writing the name of the
            proposed assignee or subtenant, as applicable, the nature of the
            proposed assignee or subtenant's business and, as applicable, the
            portion of this Lease Tenant desires to assign or the portion of
            the Premises which Tenant desires to sublease, (b) a current
            balance sheet and income statement for such proposed assignee or
            subtenant, as applicable, (c) a copy of the proposed form of
            sublease (THE "PROPOSED SUBLEASE") or proposed form of assignment
            ("PROPOSED ASSIGNMENT"), as applicable, (d) recommendations for the
            proposed assignee or subtenant, as applicable from two (2) prior
            landlords of the proposed assignee or subtenant (with the
            understanding that if such proposed assignee or subtenant does not
            have two prior landlords, then recommendations will be required
            only from such proposed assignee's or subtenant's prior landlord,
            if any), (e) the portion of the Premises which Tenant proposes to
            sublease or the percentage of Tenant's leasehold estate that Tenant
            proposes to assign, as applicable, and (e) such other information
            as Landlord may reasonably request (such documents and information,
            collectively the "REQUIRED INFORMATION").

     (b) Subject to Tenant's right under the next following sentence, Landlord
            shall have the right to terminate this Lease as to the Applicable
            Portion of the Premises (hereinafter defined), by delivering to
            Tenant, within fifteen (15) days after Landlord receives the
            Required Information, a written notice in which (i) Landlord elects
            to terminate this Lease to the Applicable Portion of the Premises
            and (ii) Landlord specifies the date on which this Lease will
            terminate as to the Applicable Portion of the Premises (the
            "SPECIFIED TERMINATION DATE"), which Specified Termination Date
            shall not be sooner than 30 days after the date of the applicable
            notice of termination, nor later than 90 days after the date of the
            applicable notice of termination. If Landlord forwards a notice of
            termination in accordance with the preceding provisions, Tenant
            shall have the right to withdraw its request for Landlord's consent
            to a Proposed Sublease or Proposed Assignment by delivering
            Landlord written notice thereof (each such notice a "NOTICE OF
            WITHDRAWAL") within five (5) days after receiving Landlord's
            termination notice. If Tenant timely delivers a Notice of
            Withdrawal, the applicable termination notice shall be deemed null
            and void and this Lease shall not terminate with respect to the
            Applicable Portion of the Premises. If Tenant fails to deliver a
            Notice of Withdrawal within the required 3-day period, then
            Landlord's

                                      27

<PAGE>   36

            applicable notice of termination shall be and remain in full force
            and effect and this Lease shall terminate on the Specified 
            Termination Date with respect to the Applicable Portion of the 
            Premises (the Applicable Portion of the Premises covered by each 
            such notice of termination which remains in full force and effect,
            the "TERMINATED SPACE"). The "APPLICABLE PORTION OF THE PREMISES" 
            shall mean the following: (A) if the applicable Proposed Sublease 
            is for the entire Premises or the applicable Proposed Assignment 
            is for Tenant's leasehold estate in all of the Premises, the 
            Applicable Portion of the Premises shall mean the entire Premises;
            (B) if the Proposed Sublease covers less than all of the Premises 
            or the Proposed Assignment is an assignment of Tenant's leasehold 
            estate in less than all of the Premises, the Applicable Portion of
            the Premises shall mean the portion of the Premises that is the 
            subject of the applicable Proposed Sublease or the portion of the 
            Premises with respect to which Tenant proposes to assign its 
            leasehold estate pursuant to the applicable Proposed Assignment.

     (c) If Landlord does not exercise its termination right with respect to
            the Applicable Portion of the Premises within the required 15-day
            period, then Landlord shall be deemed to have waived its right to
            terminate this Lease with respect to the Applicable Portion of the
            Premises, but shall have the right to consent or withhold its
            consent to the applicable Proposed Assignment or Proposed Sublease
            by delivering written notice thereof to Tenant within five (5) days
            after such 15-day period. If Landlord does not exercise its right
            to consent or withhold its consent in respect of a Proposed
            Assignment or Proposed Sublease, as applicable, within such 5-day
            period, then Landlord shall be deemed to have consented to the
            Proposed Assignment or Proposed Sublease, as applicable.

11.202 EFFECT OF TERMINATION. If the Terminated Space is the entire Premises,
       Base Rent and Additional Rent shall be prorated to the Termination Date.
       If the Terminated Space is less than the entire Premises, then, from and
       after the applicable Specified Termination Date, (i) the Base Rent shall
       be reduced by the amount of Base Rent that was being paid in respect of
       the Terminated Space as of the applicable Specified Termination Date,
       (iii) the Agreed Rentable Area of the Premises shall be decreased by the
       square feet of rentable area of the Terminated Space, (iv) Tenant's
       estimated payments of Additional Rent shall be recalculated on the basis
       of the revised Agreed Rentable Area of the Premises, (v) if the
       Terminated Space adjoins another portion of the Premises, Tenant shall,
       at Tenant's sole cost and expense, construct and finish such demising
       walls as are necessary to physically separate the Premises from the
       Terminated Space, and (vi) if the Terminated Space is part of a floor
       which is fully included in the Premises, Landlord shall have the right
       (a) to construct and finish in accordance with Building standards or to
       cause Tenant to construct and finish in accordance with Building
       standards such demising walls as are necessary (x) to construct a public
       corridor so as to convert the floor to a multi-tenant floor and (y) to
       convert the restrooms on such floor (including access thereto) to
       restrooms which will serve the entire floor, as opposed to only the
       Premises and (b) to make such revisions, if any, are necessary, to
       properly light, heat, cool and ventilate the public corridor and public
       restrooms. The alterations performed by Tenant pursuant to this
       paragraph shall be deemed Installations and therefore subject to the
       provisions of subsection 6.303.

SECTION 11.3 LANDLORD'S RIGHTS RELATING TO ASSIGNEE OR SUBTENANT. Without
limiting Landlord's consent rights and as a condition to obtaining Landlord's
consent, (i) each assignee must assume all obligations under this Lease, and
(ii) each sublessee must confirm that its sublease is subject and subordinate
to this Lease. In addition, each assignee and sublessee shall agree to cause
the Premises to comply at all times with all requirements of the Disability
Acts (as amended), including, but not limited to, obligations arising out of or
associated with such assignee's or subtenant's use of or activities or business
operations conducted within the Premises. No assignee or sublessee of the
Premises or any portion thereof may assign or sublet the Premises or any
portion thereof. To the extent the rentals or income derived from any sublease
or assignment exceed the sum of the rentals payable under this Lease in respect
of the portion of the Premises covered by such sublease or assignment (such
excess, the "EXCESS SUBLEASE RENTS"), Landlord shall be entitled to fifty
percent (50%) of such Excess Sublease Rents and Tenant shall pay Landlord its
share of Excess Sublease Rents promptly after receipt thereof. If this Lease or
any part hereof is assigned or the Premises or any part thereof are sublet,
Landlord may at its option collect directly from such assignee or sublessee all
rents becoming due to Tenant under such assignment or sublease, in which event
Landlord shall first apply such rent against any sums due to Landlord by Tenant
hereunder and Tenant shall be entitled to the remainder, if any, but only to
the extent of Tenant's share of Excess Sublease Rents. Tenant hereby authorizes
and directs any such assignee or sublessee to make such payments of rent direct
to Landlord upon receipt of notice from Landlord and Tenant agrees that any
such payments made by an assignee or sublessee to Landlord shall, to the extent
of the payments so made, be a full and complete release and discharge of rent
owed to Tenant by such assignee or sublessee. No direct collection by Landlord
from any such assignee or sublessee shall be construed to constitute a novation
or a release of Tenant or any guarantor of Tenant from the further performance
of its obligations hereunder. Receipt by Landlord of rent from any assignee,
sublessee or occupant of the Premises or any part thereof shall not be deemed a
waiver of the above covenant in this Lease against assignment and subletting or
a release of Tenant under this Lease. In the event that, following an
assignment or subletting, this Lease or the rights and obligations of Tenant
hereunder are terminated for any reason, including without limitation in
connection with an Event of Default by or bankruptcy of Tenant (which, for the
purposes of this Section 11.3, shall include all persons or entities claiming
by or through Tenant), Landlord may, at its sole option, consider this Lease to
be thereafter a direct lease to the assignee or subtenant of Tenant upon the
terms and conditions contained in this Lease.

SECTION 11.4 ASSIGNMENT AND BANKRUPTCY.

11.401 ASSIGNMENTS AFTER BANKRUPTCY. If, pursuant to applicable bankruptcy law
       (as hereinafter defined), Tenant (or its successor in interest
       hereunder) is permitted to assign this Lease in disregard of the
       restrictions contained in this Article 11 (or if this Lease shall be
       assumed by a trustee for such person), the trustee or assignee shall
       cure any default under this Lease and shall provide adequate assurance
       of future performance by the trustee or assignee including (1) of the
       source of payment of Basic Annual Rent and performance of other
       obligations under this Lease (for which adequate assurance shall mean
       the deposit of cash security with Landlord in an amount equal to the sum
       of one (1) year's Basic Annual Rent, Additional Rent and other Rent then
       reserved hereunder for the calendar year preceding the year in which
       such assignment is intended to become effective, which deposit shall be
       held by Landlord, 


                                      29

<PAGE>   38

       without interest, for the balance of the Term as security for the full
       and faithful performance of all of the obligations under this Lease on
       the part of Tenant yet to be performed) and that any such assignee of
       this Lease shall have a net worth exclusive of good will, computed in
       accordance with the generally accepted accounting principles, equal to
       at least ten (10) times the aggregate of the Basic Annual Rent reserved
       hereunder; and (2) that the use of the Premises shall be in accordance
       with the requirements of Article 3 hereof and, further, shall in no way
       diminish the reputation of the Building as a first-class office building
       or impose any additional burden upon the Building or increase the
       services to be provided by Landlord. If all defaults are not cured and
       such adequate assurance is not provided within sixty (60) days after
       there has been an order for relief under applicable bankruptcy law, then
       this Lease shall be deemed rejected, Tenant or any other person in
       possession shall vacate the Premises, and Landlord shall be entitled to
       retain any Basic Annual Rent, Additional Rent and any other Rent,
       together with any security deposit previously received from the Tenant,
       and shall have no further liability to Tenant or any person claiming
       through Tenant or any trustee.

11.402 BANKRUPTCY OF ASSIGNEE. If Tenant assigns this Lease to any party and
       such party or its successors or representatives causes termination or
       rejection of this Lease pursuant to applicable bankruptcy law, then,
       notwithstanding any such termination or rejection, Tenant (A) shall
       remain fully liable for the performance of all covenants, agreements,
       terms, provisions and conditions contained in this Lease, as though the
       assignment never occurred and (B) shall, without in any way limiting the
       foregoing, in writing ratify the terms of this Lease, as same existed
       immediately prior to the termination or rejection.

              ARTICLE 12--TRANSFERS BY LANDLORD, SUBORDINATION AND
                         TENANT'S ESTOPPEL CERTIFICATE

SECTION 12.1 SALE OF THE PROPERTY. In the event of any transfer of title to the
Building, the transferor shall automatically be relieved and freed of all
obligations of Landlord under this Lease accruing after such transfer, provided
that if a Security Deposit has been made by Tenant, Landlord shall not be
released from liability with respect thereto unless Landlord transfers the
Security Deposit to the transferee.

SECTION 12.2 SUBORDINATION, ATTORNMENT AND NOTICE. This Lease is subject and
subordinate to (i) any lease now or hereafter existing wherein Landlord is the
tenant (each such lease, a "GROUND LEASE") and to the liens of any and all now
or hereafter existing mortgages and deeds of trust affecting the Property or
any portion thereof (each such mortgage and deed of trust, a "MORTGAGE"), (ii)
any and all advances (including interest thereon) to be made under any such
Ground Lease or Mortgage and (iii) all modifications, consolidations, renewals,
replacements and extensions of any such Ground Lease or Mortgage; provided that
the foregoing subordination is conditioned upon and subject to the lessor under
any such Ground Lease and the holder of any such Mortgage delivering to and
entering into with Tenant a non-disturbance (each a "NON-DISTURBANCE
AGREEMENT"). Tenant also agrees that any lessor under a Ground Lease and any
mortgagee or trustee under a Mortgage may elect (which election shall be
revocable) to have this Lease superior to any Ground Lease or lien of its
Mortgage, as applicable, and, in the event of such election and upon
notification by such lessor, mortgagee or trustee to Tenant to that effect,
this Lease shall be deemed superior to the said Ground Lease or Mortgage, as
applicable, whether this Lease 

                                      30

<PAGE>   39

is dated prior to or subsequent to the date of said Ground Lease or Mortgage.
Tenant shall, in the event of the sale or assignment of Landlord's interest in
the Premises (except in a sale-leaseback financing transaction), or in the
event of the termination of any Ground Lease, attorn to and recognize such
purchaser, assignee, mortgagee or lessor, as applicable, as Landlord under this
Lease, provided that the lessor under such Ground Lease or the holder of any
such Mortgage has delivered to and entered into with Tenant a Non-Disturbance
Agreement. Tenant shall, in the event of a termination of a Ground Lease or any
proceedings brought for the foreclosure of, or in the event of the exercise of
the power of sale under, any mortgage or deed of trust covering the Premises,
attorn to and recognize the lessor under such Ground Lease or the purchaser at
such sale, assignee or mortgagee, as the case may be, as Landlord under this
Lease, provided that the lessor under such Ground Lease or the holder of any
such mortgage or deed of trust has delivered to and entered into with Tenant a
Non-Disturbance Agreement. Provided a Non-Disturbance Agreement has been
entered into by the parties, the above subordination and attornment clauses
shall be self-operative and no further instruments of subordination or
attornment need be required by any mortgagee, trustee, lessor, purchaser or
assignee. In confirmation thereof, Tenant agrees that, upon the request of
Landlord, or any such lessor, mortgagee, trustee, purchaser or assignee, Tenant
shall execute and deliver a subordination and attornment agreement in form
reasonably satisfactory to Tenant.

SECTION 12.3 TENANT'S ESTOPPEL CERTIFICATE. Tenant shall, within five (5) days
after receiving a written request from Landlord or any mortgagee of Landlord,
without additional consideration, deliver an estoppel certificate, consisting
of reasonable statements required by Landlord, any mortgagee or purchaser of
any interest in the Property, which statements may include but shall not be
limited to the following: this Lease is in full force and effect, with rental
paid through a specified date; this Lease has not been modified or amended;
Landlord is not in default and Landlord has fully performed all of Landlord's
obligations hereunder; and such other statements as may reasonably be required
by the requesting party. If Tenant is unable to make any of the statements
contained in the estoppel certificate because the same is untrue, Tenant shall
with specificity state the reason why such statement is untrue. Tenant shall,
if requested by Landlord or any such mortgagee, deliver to Landlord a fully
executed instrument in form reasonably satisfactory to Landlord evidencing the
agreement of Tenant to the mortgage or other hypothecation by Landlord of the
interest of Landlord hereunder.

                              ARTICLE 13--DEFAULT

SECTION 13.1 DEFAULTS BY TENANT. The occurrence of any of the events described
in subsections 13.101 through 13.108 shall constitute a default by Tenant under
this Lease.

13.101 FAILURE TO PAY RENT. With respect to the first two payments of Rent not
       made by Tenant when due in any twelve (12) month period, the failure by
       Tenant to make either such payment to Landlord within three (3) business
       days after Tenant receives written notice specifying that the payment
       was not made when due. With respect to any other payment of Rent, the
       failure by Tenant to make such payment of Rent to Landlord when due, no
       notice of any such failure being required.

13.102 FAILURE TO PERFORM. Except for a failure covered by subsection 13.101
       above or 13.103 below, any failure by Tenant to observe and perform any
       provision of this Lease to be 

                                      31

<PAGE>   40

       observed or performed by Tenant where such failure continues for thirty
       (30) days after written notice to Tenant, provided that if such failure
       cannot be cured within said thirty (30) day period, Tenant shall not be
       in default hereunder so long as Tenant commences curative action within
       such thirty (30) day period, diligently and continuously pursues the
       curative action and fully and completely cures the failure within ninety
       (90) days after such written notice to Tenant.

13.103 CONTINUAL FAILURE TO PERFORM. The third failure by Tenant in any twelve
       (12) month period to perform and observe a particular provision of this
       Lease to be observed or performed by Tenant (other than the failure to
       pay Rent, which in all instances will be covered by subsection 13.101
       above), no notice being required for any such third failure.

13.104 BANKRUPTCY, INSOLVENCY, ETC. Tenant or any guarantor of Tenant's
       obligations hereunder (hereinafter called "GUARANTOR", whether one (1)
       or more), (i) cannot meet its obligations as they become due, (ii)
       becomes or is declared insolvent according to any law, (iii) makes a
       transfer in fraud of creditors according to any applicable law, (iv)
       assigns or conveys all or a substantial portion of its property for the
       benefit or creditors or (v) Tenant or Guarantor files a petition for
       relief under the Federal Bankruptcy Code or any other present or future
       federal or state insolvency, bankruptcy or similar law (collectively,
       "applicable bankruptcy law"); a receiver or trustee is appointed for
       Tenant or Guarantor or its property; the interest of Tenant or Guarantor
       under this Lease is levied on under execution or under other legal
       process; any involuntary petition is filed against Tenant or Guarantor
       under applicable bankruptcy law; or any action under applicable
       bankruptcy law is taken to reorganize or modify Tenant's or Guarantor's
       capital structure if either Tenant or Guarantor be a corporation or
       other entity (provided that no such levy, execution, legal process or
       petition filed against Tenant or Guarantor shall constitute a breach of
       this Lease if Tenant or Guarantor shall vigorously contest the same by
       appropriate proceedings and shall remove or vacate the same within
       ninety (90) days from the date of its creation, service or filing).

13.105 LOSS OF RIGHT TO DO BUSINESS. If Tenant is a corporation or limited
       partnership, Tenant fails to maintain its right to do business in the
       State of Texas or fails to pay any applicable annual franchise taxes as
       and when same become finally due and payable and such failure continues
       for ten (10) business days after Tenant receives written notice thereof
       from the State of Texas.

13.106 DISSOLUTION OR LIQUIDATION. If Tenant is a corporation or partnership,
       Tenant dissolves or liquidates or otherwise fails to maintain its
       corporate or partnership structure, as applicable.

With respect to the defaults described in subsections 13.103 through 13.105,
Landlord shall not be obligated to give Tenant notices of default and Tenant
shall have no right to cure such defaults.

SECTION 13.2 REMEDIES OF LANDLORD.

13.201 TERMINATION OF THE lEASE. Upon the occurrence of a default by Tenant
       hereunder, Landlord may, without judicial process, terminate this Lease
       by giving written notice thereof to Tenant (whereupon all obligations
       and liabilities of Landlord hereunder shall terminate) and, without

                                      32
<PAGE>   41


       further notice and without liability, repossess the Premises. Landlord
       shall be entitled to recover all loss and damage Landlord may suffer by
       reason of such termination, whether through inability to relet the
       Premises on satisfactory terms or otherwise, including without
       limitation, the following (without duplication of any element of
       damages):

     (a) accrued Rent to the date of termination and Late Charges, plus
            interest thereon at the rate established under Section 15.10 below
            from the date due through the date paid or date of any judgment or
            award by any court of competent jurisdiction, the unamortized cost
            of Tenant's Improvements, brokers' fees and commissions, attorneys'
            fees, moving allowances and any other costs incurred by Landlord in
            connection with making or executing this Lease, the cost of
            recovering the Premises and the costs of reletting the Premises
            (including, without limitation, advertising costs, brokerage fees,
            leasing commissions, reasonable attorneys' fees and refurbishing
            costs and other costs in readying the Premises for a new tenant);

     (b) the present value of the Rent (discounted at a rate of interest equal
            to eight percent [8%] per annum [the "DISCOUNT RATE"]) that would
            have accrued under this Lease for the balance of the Lease term but
            for such termination, reduced by the reasonable fair market rental
            value of the Premises for such balance of the Lease term
            (determined from the present value of the actual base rents,
            discounted at the Discount Rate, received and to be received from
            Landlord's reletting of the Premises or, if the Premises are not
            relet, the base rents, discounted at the Discount Rate, that would
            be received from a comparable lease and comparable tenant for a
            comparable term and taking into account among other things, the
            condition of the Premises, market conditions and the period of time
            the Premises may reasonably remain vacant before Landlord is able
            to re-lease the same to a suitable replacement tenant, it being
            agreed that Landlord shall have no obligation to relet or attempt
            to relet the Premises);

     (c) plus any other costs or amounts necessary to compensate Landlord
            for its damages.

      Notwithstanding the preceding provisions, Tenant shall not be liable for
      consequential damages incurred by Landlord, save and except for
      consequential damages incurred by Landlord as a result of Tenant's
      holdover in the Premises following the expiration or earlier termination
      of this Lease.

13.202 REPOSSESSION AND RE-ENTRY. Upon the occurrence of a default by Tenant
       hereunder, Landlord may, without judicial process, immediately terminate
       Tenant's right of possession of the Premises (whereupon all obligations
       and liability of Landlord hereunder shall terminate), but not terminate
       this Lease, and, without notice, demand or liability, enter upon the
       Premises or any part thereof, take absolute possession of the same,
       expel or remove Tenant and any other person or entity who may be
       occupying the Premises and change the locks. If Landlord terminates
       Tenant's possession of the Premises under this subsection 13.202, (i)
       Landlord shall have no obligation whatsoever to tender to Tenant a key
       for new locks installed in the Premises, (ii) Tenant shall have no
       further right to possession of the Premises and (iii) Landlord shall
       have no obligation whatsoever to relet or attempt to relet the Premises.
       Landlord may, however, at its sole option relet the Premises or any part

                                      33

<PAGE>   42


       thereof for such terms and such rents as Landlord may in its sole        
       discretion elect. If Landlord elects to relet the Premises, rent
       received by Landlord from such reletting shall be applied first, to the
       payment of any indebtedness other than Rent due hereunder from Tenant to
       Landlord (in such order as Landlord shall designate), second, to the
       payment of any cost of such reletting, including, without limitation,
       refurbishing costs, reasonable attorneys' fees, advertising costs,
       brokerage fees and leasing commissions and third, to the payment of Rent
       due and unpaid hereunder (in such order as Landlord shall designate),
       and Tenant shall Satisfy and pay to Landlord any deficiency upon demand
       therefor from time to time. Landlord shall not be responsible or liable
       for any failure to relet the Premises or any part thereof or for any
       failure to collect any rent due upon any such reletting. No such
       re-entry or taking of possession of the Premises by Landlord shall be
       construed as an election on Landlord's part to terminate this Lease
       unless a written notice of such termination is given to Tenant pursuant
       to subsection 13.201 above. If Landlord relets the Premises, either
       before or after the termination of this Lease, all such rentals received
       from such lease shall be and remain the exclusive property of Landlord
       and Tenant shall not be, at any time, entitled to recover any such
       rental. Landlord may at any time after a reletting elect to terminate
       this Lease.

13.203 CURE OF DEFAULT. Upon the occurrence of a default hereunder by Tenant,
       Landlord may, without judicial process and without having any liability
       therefor, enter upon the Premises and do whatever Tenant is obligated to
       do under the terms of this Lease and Tenant agrees to reimburse Landlord
       on demand for any expenses which Landlord may incur in effecting
       compliance with Tenant's obligations under this Lease, and Tenant
       further agrees that Landlord shall not be liable for any damages
       resulting to Tenant from such action, whether caused by the negligence
       of Landlord or otherwise.

13.204 CONTINUING OBLIGATIONS. No repossession of or re-entering upon the
       Premises or any part thereof pursuant to subsection 13.202 or 13.203
       above or otherwise and no reletting of the Premises or any part thereof
       pursuant to subsection 13.202 above shall relieve Tenant or any
       Guarantor of its liabilities and obligations hereunder, all of which
       shall survive such repossession or re-entering. In the event of any such
       repossession of or re-entering upon the Premises or any part thereof by
       reason of the occurrence of a default, Tenant will continue to pay to
       Landlord Rent required to be paid by Tenant.

SECTION 13.3 DEFAULTS BY LANDLORD. Landlord shall be in default under this
Lease if and only if Landlord fails to perform any of its obligations hereunder
and said failure continues for a period of thirty (30) days after Tenant
delivers written notice thereof to Landlord (to each of the addresses required
by this Section) and each mortgagee who has a lien against any portion of the
Property and whose name and address has been provided to Tenant, provided that
if such failure cannot reasonably be cured within said thirty (30) day period,
Landlord shall not be in default hereunder if the curative action is commenced
within said thirty (30) day period and is thereafter diligently pursued until
cured. In no event shall (i) Tenant claim a constructive or actual eviction or
that the Premises have become unsuitable hereunder or (ii) a constructive or
actual eviction or breach of the implied warranty of suitability be deemed to
have occurred under this Lease, prior to the expiration of the notice and cure
periods provided under this Section 13.3. Any notice of a failure to perform by
Landlord shall be sent to Landlord at the addresses and to the attention of the


                                      34

<PAGE>   43

parties set forth in the Basic Lease Provisions. Any notice of a failure to
perform by Landlord not sent to Landlord at all addresses and/or to the
attention of all parties required under this Section and to each mortgagee who
is entitled to notice or not sent in compliance with Article 14 below shall be
of no force or effect.

SECTION 13.4 LANDLORD'S LIABILITY.

13.401 TENANT'S RIGHTS IN RESPECT OF LANDLORD DEFAULT. Tenant is granted no
       contractual right of termination by this Lease, except to the extent and
       only to the extent set forth in Articles 7 and 8 above. If Tenant shall
       recover a money judgment against Landlord, such judgment shall be
       satisfied only out of the right, title and interest of Landlord in the
       Property as the same may then be encumbered and Landlord shall not be
       liable for any deficiency. If Landlord is found to be in default
       hereunder by reason of its failure to give a consent that it is required
       to give hereunder, Tenant's sole remedy will be an action for specific
       performance or injunction. The foregoing sentence shall in no event be
       construed as mandatorily requiring Landlord to give consents under this
       Lease. In no event shall Landlord be liable to Tenant for consequential
       or special damages by reason of a failure to perform (or a default) by
       Landlord hereunder or otherwise. In no event shall Tenant have the right
       to levy execution against any property of Landlord other than its
       interest in the Property as hereinbefore expressly provided.

13.402 CERTAIN LIMITATIONS ON LANDLORD'S LIABILITY. UNLESS COVERED BY
       SUBSECTION 7.502 ABOVE OR CAUSED BY LANDLORD'S GROSS NEGLIGENCE OR
       WILLFUL MISCONDUCT AND WITHOUT LIMITING THE PROVISIONS OF SECTION 7.4,
       LANDLORD SHALL NOT BE LIABLE TO TENANT FOR ANY CLAIMS, ACTIONS, DEMANDS,
       COSTS, EXPENSES, DAMAGE OR LIABILITY OF ANY KIND (i) arising out of the
       use, occupancy or enjoyment of the Premises by Tenant or any person
       therein or holding under Tenant or by or through the acts or omissions
       of any of their respective employees, officers, agents, invitees or
       contractors, (ii) caused by or arising out of fire, explosion, falling
       sheetrock, gas, electricity, water, rain, snow or dampness, or leaks in
       any part of the Premises, (iii) caused by or arising out of damage to
       the roof, pipes, appliances or plumbing works or any damage to or
       malfunction of heating, ventilation or air conditioning equipment, (iv)
       caused by tenants or any persons either in the Premises or elsewhere in
       the Building (other than Common Areas) or by occupants of property
       adjacent to the Building or Common Areas or by the public or by the
       construction of any private, public or quasi-public work or (v) caused
       by any act, neglect or negligence of Tenant. In no event shall Landlord
       be liable to Tenant for any loss of or damage to property of Tenant or
       of others located in the Premises, the Building or any other part of the
       Property by reason of theft or burglary.

on any permitted assign or successor of Tenant under this Lease. The provisions
of this Section shall survive any termination of this Lease. Tenant represents
to Landlord:

lien on and security interest in and to all goods, equipment, furnishings,

secured party under the Texas Business and Commerce Code and this lien and
security interest may be foreclosed by process of law. The requirement of
reasonable notice prior to any sale under Article 9 of the Texas Business and
Commerce Code shall be met if such notice is given in the manner prescribed

the provisions of this Section shall be deemed to have been a public sale
conducted in a commercially reasonable manner if held in the Premises after the
time, place and method of sale and a general description of the types of
property to be sold have been advertised for ten (10) consecutive days prior to
the date of sale in a daily newspaper published in the county in Texas where
the Building is located.

SECTION 13.7 CUMULATIVE REMEDIES. No right or remedy herein conferred upon or
reserved to Landlord or Tenant is intended to be exclusive of any other right
or remedy set forth herein or otherwise available to Landlord or Tenant at law
or in equity and each and every right and remedy shall be cumulative and in
addition to any other right or remedy given hereunder or now or hereafter
existing at law or in equity or by statute. In addition to the other remedies
provided in this Lease and without limiting the preceding sentence, Landlord
and Tenant shall be entitled, to the extent permitted by applicable law, to
injunctive relief in case of the violation, or attempted or threatened
violation, of any of the covenants, agreements, conditions or provisions of
this Lease, or to a decree compelling performance of any of the covenants,
agreements, conditions or provisions of this Lease, or to any other remedy
allowed to Landlord or Tenant, as applicable, at law or in equity.

SECTION 13.8 VACATING PREMISES. In the event that Tenant ceases all or
substantially all of its business operations in the Premises for a period of
more than ninety (90) calendar days, Landlord shall have the right to terminate

                              ARTICLE 14--NOTICES

Any notice or communication required or permitted in this Lease shall be given
in writing, sent by (a) personal delivery, with proof of delivery, (b)
expedited delivery service, with proof of delivery, (c) United States mail,

such other address or to the attention of such other person as shall be
designated from time to time in writing by the applicable party and sent in
accordance herewith. Notice also may be given by telex or fax, provided each
such transmission is confirmed (and such confirmation is supported by
documented evidence) as received and further provided a telex or fax number, as
the case may be, is set forth in Item 14 of the Basic Lease Provisions. Any
such notice or communication shall be deemed to have been given either at the
time of personal delivery or, in the case of delivery service or mail, as of
the date of first attempted delivery at the address and in the manner provided
herein, or in the case of telegram or telex or fax, upon receipt.

                      ARTICLE 15--MISCELLANEOUS PROVISIONS

SECTION 15.1 BUILDING NAME AND ADDRESS. Tenant shall not, without the written
consent of Landlord, use the name of the Building for any purpose other than as
the address of the business to be conducted by Tenant in the Premises and in no
event shall Tenant acquire any rights in or to such names. Landlord shall have
the right at any time to change the name, number or designation by which the
Building is known.

SECTION 15.2 SIGNAGE. Tenant shall not inscribe, paint, affix or display any
signs, advertisements or notices on or in the Building, except for such tenant
identification information as Landlord customarily permits to be included or
shown on the directory in the main lobby and adjacent to or on the access door
or doors to the Premises. Directory information customarily shown on the
directory in the main lobby shall be a Landlord's cost.

SECTION 15.3 NO WAIVER. No waiver by Landlord or by Tenant of any provision of
this Lease shall be deemed to be a waiver by either party of any other
provision of this Lease. No waiver by Landlord of any breach by Tenant shall be
deemed a waiver of any subsequent breach by Tenant of the same or any other
provision. No waiver by Tenant of any breach by Landlord shall be deemed a
waiver of any subsequent breach by Landlord of the same or any other provision.
The failure of Landlord or Tenant to insist at any time upon the strict
performance of any covenant or agreement or to exercise any option, right,
power or remedy contained in this Lease shall not be construed as a waiver or a
relinquishment thereof for the future. Landlord's consent to or approval of any
act by Tenant requiring Landlord's consent or approval shall not be deemed to
render unnecessary the obtaining of Landlord's consent to or approval of any
subsequent act of Tenant. Tenant's consent to or approval of any act by
Landlord requiring Tenant's consent or approval shall not be deemed to render
unnecessary the obtaining of Tenant's consent to or approval of any subsequent
act of Landlord. No act or thing done by Landlord or Landlord's agents during
the term of this Lease shall

                                      37

<PAGE>   46

be deemed an acceptance of a surrender of the Premises, unless done in writing
signed by Landlord. The delivery of the keys to any employee or agent of
Landlord shall not operate as a termination of this Lease or a surrender of the
Premises. The acceptance of any Rent by Landlord following a breach of this
Lease by Tenant shall not constitute a waiver by Landlord of such breach or any
other breach. The payment of Rent by Tenant following a breach of this Lease by
Landlord shall not constitute a waiver by Tenant of any such breach or any
other breach. No waiver by Landlord or Tenant of any provision of this Lease
shall be deemed to have been made unless such waiver is expressly stated in
writing signed by the waiving party. No payment by Tenant or receipt by
Landlord of a lesser amount than the monthly installment of Rent due under this
Lease shall be deemed to be other than on account of the earliest Rent due
hereunder, nor shall any endorsement or statement on any check or any letter
accompanying any check or payment as Rent be deemed an accord and satisfaction
and Landlord may accept such check or payment without prejudice to Landlord's
right to recover the balance of such rent or pursue any other remedy which may
be available to Landlord.

SECTION 15.4 APPLICABLE LAW. This Lease shall be governed by and construed in
accordance with the laws of the State of Texas.

SECTION 15.5 COMMON AREAS, SERVICE CORRIDORS AND SERVICE AREAS. "COMMON AREAS"
will mean all areas, spaces, facilities and equipment (whether or not located
within the Building) made available by Landlord for the common and joint use of
Landlord, Tenant and others designated by Landlord using or occupying space in
the Building, including but not limited to, tunnels, walkways, sidewalks and
driveways necessary for access to the Building, Building lobbies, landscaped

the public, service elevators (provided that such service elevators shall be

such parking areas shall be subject to the provisions of EXHIBIT F attached
hereto. "SERVICE CORRIDORS" shall mean all loading docks, loading areas and all
corridors that are not open to the public but which are available for use by
Tenant and others designated by Landlord. "SERVICE AREAS" will refer to areas,
spaces, facilities and equipment serving the Building (whether or not located
within the Building) but to which Tenant and other occupants of the Building
will not have access, including, but not limited to, mechanical, telephone,
electrical and similar rooms and air and water refrigeration equipment. Tenant
is hereby granted a nonexclusive right to use the Common Areas and Service
Corridors during the term of this Lease for their intended purposes, in common
with others designated by Landlord, subject to the terms and conditions of this
Lease, including, without limitation, the Rules and Regulations. The Building,
Common Areas, Service Corridors and Service Areas will be at all times under
the exclusive control, management and operation of the Landlord. Tenant agrees
and acknowledges that the Premises (whether consisting of less than one floor
or consisting of one or more full floors within the Building) do not include,
and Landlord hereby expressly reserves for its sole and exclusive use, any and
all mechanical, electrical, telephone and similar rooms, janitor closets,
elevator, pipe and other vertical shafts and ducts, flues, stairwells, any area
above the acoustical ceiling and any other areas not specifically shown on
EXHIBIT B as being part of the Premises. Tenant acknowledges that pipes, ducts,
conduits, wires and equipment serving

                                      38

<PAGE>   47

other parts of the Building may be located above acoustical ceiling surfaces,
below floor surfaces or within walls in the Premises.

SECTION 15.6 SUCCESSORS AND ASSIGNS. Subject to Article 11 hereof, all of the
covenants, conditions and provisions of this Lease shall be binding upon and
shall inure to the benefit of the parties hereto and their respective heirs,
personal representatives, successors and assigns.

SECTION 15.7 BROKERS. Tenant warrants that it has had no dealings with any real
estate broker or agent in connection with the negotiation of this Lease,
excepting only the brokers named in Item 10. of the Basic Lease Provisions and
that it knows of no other real estate brokers or agents who are or might be
entitled to a commission in connection with this Lease. Tenant agrees to
indemnify and hold harmless Landlord from and against any liability or claim,
whether meritorious or not, arising in respect to brokers and/or agents not so
named. Landlord has agreed to pay the fees of the brokers (but only the broker)
named in Item 10 of the Basic Lease Provisions to the extent that Landlord has
agreed to do so pursuant to a written agreement with such broker.

SECTION 15.8 SEVERABILITY. If any provision of this Lease or the application
thereof to any person or circumstances shall be invalid or unenforceable to any
extent, the application of such provisions to other persons or circumstances
and the remainder of this Lease shall not be affected thereby and shall be
enforced to the greatest extent permitted by law.

SECTION 15.9 EXAMINATION OF LEASE. Submission by Landlord of this instrument to
Tenant for examination or signature does not constitute a reservation of or
option for lease. This Lease will be effective as a lease or otherwise only
upon execution by and delivery to both Landlord and Tenant.

SECTION 15.10 INTEREST ON TENANT'S OBLIGATIONS. Any amount due from Tenant to
Landlord which is not paid within thirty (30) days after the date due shall
bear interest at the lower of (i) eighteen percent (18%) per annum or (ii) the
highest rate from time to time allowed by applicable law, from the date such
payment is due until paid, but the payment of such interest shall not excuse or
cure the default.

SECTION 15.11 TIME. Time is of the essence in this Lease and in each and all of
the provisions hereof. Whenever a period of days is specified in this Lease,
such period shall refer to calendar days unless otherwise expressly stated in
this Lease.

SECTION 15.12 DEFINED TERMS AND MARGINAL HEADINGS. The words "Landlord" and
"Tenant" as used herein shall include the plural as well as singular. If more
than one person is named as Tenant, the obligations of such persons are joint

construction or interpretation of any part of this Lease.

SECTION 15.14 FORCE MAJEURE. Whenever a period of time is herein prescribed for
action to be taken by Landlord or Tenant, the party taking the action shall not
be liable or responsible for, and there shall be excluded from the computation
for any such period of time, any delays due to strikes, riots, acts of God,
shortages of labor or materials, war, governmental laws, regulations or
restrictions or any other causes of any kind whatsoever which are beyond the
reasonable control of such party (each of the foregoing is herein referred to
as an "event of force majeure" or "force majeure"); provided, however, in no

Building or the Property), except as herein expressly set forth and no rights,
easements or licenses are acquired by Tenant by implication or otherwise except
as expressly set forth in the provisions of this Lease.

SECTION 15.17 PARKING. EXHIBIT F attached hereto sets forth the agreements
between Landlord and Tenant relating to parking. Parking and delivery areas for

only permit parking by its employees, customers and agents of automobiles in
appropriate designated parking areas.

SECTION 15.18 ATTORNEYS' FEES. In the event of any legal action or proceeding
brought by either party against the other arising out of this Lease, the

recover reasonable attorneys' fees and costs incurred in such action
(including, without limitation, all costs of appeal) and such amount shall be
included in any judgment rendered in such proceeding.

SECTION 15.19 NO LIGHT, AIR OR VIEW EASEMENT. Any diminution or shutting off of
light, air or view by any structure which may be erected on the Property or
lands adjacent to the Property shall in no way affect this Lease or impose any
liability on Landlord (even if Landlord is the adjacent land owner).

SECTION 15.20 RELOCATION. Upon 120 days advance written notice to Tenant (the
"RELOCATION NOTICE"), Landlord shall have the right to relocate Tenant to other
space in the Building above the 23rd floor of the Building (the "SUBSTITUTE
PREMISES") provided the rentable area of such other space is not more than 110%
or less than 90% of the rentable area of the Premises, and further provided the
ratio of interior space to exterior window space is substantially similar to
such ratio for the current premises. Landlord shall pay all reasonable
out-of-pocket expenses of any such relocation, including the expenses of moving

B attached hereto. If requested by Landlord, Tenant shall execute an amendment
to this Lease evidencing the foregoing.

SECTION 15.21 SURVIVAL OF INDEMNITIES. Each indemnity agreement and hold
harmless agreement contained herein shall survive the expiration or termination
of this Lease.

SECTION 15.22 ENTIRE AGREEMENT. This Lease contains all of the agreements of
the parties hereto with respect to any matter covered or mentioned in this
Lease and no prior agreement, understanding or representation pertaining to any
such matter shall be effective for any purpose. No provision of this Lease may

                                FINISH ALLOWANCE

    This Exhibit is attached to and a part of that certain Lease Agreement
dated as of ______________________, 199___, executed by and between DALLAS MAIN
CENTER LIMITED PARTNERSHIP, a Delaware limited partnership, and AMERICAN
PHYSICIAN PARTNERS, INC., a Delaware corporation (the "Lease"). Any capitalized
term not defined herein shall have the meaning assigned to it in the provisions
of the Lease identified as the Basic Lease Provisions or Supplemental Lease
Provisions, as applicable. Landlord and Tenant mutually agree as follows:

1.      PLANS.
   
1.1     Space Plan. Landlord and Tenant have agreed to a space plan for the
        Premises dated ___________, 1996, prepared by _______________. Tenant 
        represents to Landlord that it provided the space planner and/or 
        architect, as applicable, with all information needed to cause
        compliance with the Disability Acts. TENANT SHALL BE RESPONSIBLE FOR
        AND SHALL INDEMNIFY AND HOLD HARMLESS LANDLORD FROM AND AGAINST ANY AND
        ALL CLAIMS, LIABILITIES AND EXPENSES (INCLUDING, WITHOUT LIMITATION
        REASONABLE ATTORNEYS' FEES AND EXPENSES) INCURRED BY OR ASSERTED
        AGAINST LANDLORD BY REASON OF OR IN CONNECTION WITH ANY VIOLATION OF
        THE DISABILITY ACTS ARISING FROM OR OUT OF (x) information or design
        and space plans furnished to Landlord by Tenant (or the lack of
        complete and accurate information so furnished) concerning Tenant's
        Improvements, (y) Tenant's employer-employee obligations, or (z) after
        the Commencement Date, violations by Tenant and/or Tenant's
        Improvements or the Premises not being in compliance with the
        Disability Acts as the result of changes in regulations or law or
        interpretations thereof not in effect on the Commencement Date. The
        foregoing indemnity shall not include any claims, liabilities or
        expenses (including reasonable attorneys' fees and expenses) arising
        out of the negligence or gross negligence of Landlord or Landlord's
        employees, agents or contractors. Without limiting the foregoing, if
        Landlord constructs Tenant's Improvements based on any special
        requirements or improvements required by Tenant, or upon information
        furnished by Tenant that later proves to be inaccurate or incomplete
        resulting in any violation of the Disability Acts, Tenant shall be
        solely liable to correct such violations and to bring the improvements
        into compliance with the Disability Acts as promptly as is practicable.
    

1.2     Changes to Approved Plans. If any re-drawing or re-drafting of either
        the Space Plan is necessitated by Tenant's requested changes (all of
        which shall be subject to approval by Landlord and, if applicable, the
        Texas Department of Licensing & Regulation and any other governmental
        agency or authority to which the plans and specifications are required
        to be submitted), the expense of any such re-drawing or re-drafting
        required in connection therewith and the expense of any work and
        improvements necessitated by such re-drawing or re-drafting will be
        charged to Tenant.

2.      CONSTRUCTION AND COSTS OF TENANT'S IMPROVEMENTS.

2.1     Construction Obligation and Finish Allowance.

        (a)    Landlord agrees to construct Tenant's Improvements, at Tenant's
               cost and expense; provided, however, Landlord shall provide
               Tenant with an allowance up to $1.00 per square foot of Rentable
               Area in the Premises (the "FINISH ALLOWANCE"), which allowance
               shall be disbursed by Landlord, from time to time, for payment
               of (in the following priority) the following costs (collectively
               referred to as the "PERMITTED COSTS"): (i) the contract sum
               required to be paid to the general contractor engaged to
               construct Tenant's Improvements (the "CONTRACT SUM"), (ii) the
               fees of the preparer of the Construction Plans, and (iii) such
               other costs related to relocating to or moving into the
               Premises.

        (b)    Title to any equipment, appliances, furnishings or personalty
               installed in the Premises and purchased with any portion of the
               Finish Allowance shall pass to Landlord upon payment of the
               invoice cost thereof and Tenant shall not remove any such
               equipment, appliances, furnishings or personalty from the
               Premises without Landlord's express, prior written consent or
               unless requested by Landlord in connection with the expiration
               or earlier termination of the Lease.

        (c)    "TENANT'S IMPROVEMENTS" are hereby defined to mean the
               following:

                (a) changing existing hardware in the Premises to Building
                    standard levard hardware;

                (b) cleaning carpets; and

                (c) install demising wall shown on Schedule I attached to this
                    Work Letter.

2.2     Bidding. Within five (5) days after both Landlord and Tenant agree to
        the Construction Plans, Landlord shall request at least three (3)
        mutually acceptable contractors authorized to perform work in the
        Building to bid the construction of Tenant's Improvements under a lump
        sum contract. Landlord agrees that Tenant shall have the right to
        participate in the preparation of the bid instructions, attend the bid
        opening, and clarify and qualify all bids. Tenant shall have three (3)
        business days after the bid opening within which to accept one of the
        submitted bids. Tenant shall have the right to required submitters of
        bids to clarify their bids, if necessary, provided, however, no
        contractor shall be permitted to deliver clarifications more than three
        (3) business days after bid opening. If Tenant fails to accept one of
        the submitted bids by the expiration of the third business day
        following opening of bids, then Tenant shall be deemed to have approved
        the lowest submitted bid. Landlord and Tenant must approve (or be
        deemed to have approved) the Contract Sum for the construction of
        Tenant's Improvements in writing prior to the commencement of
        construction.


                                       2


<PAGE>   59

2.3     Excess Costs. If the sum of the Permitted Costs exceeds the Finish
        Allowance, then Tenant shall pay all such excess costs ("EXCESS
        COSTS"). Tenant shall remit to Landlord an amount (the "PREPAYMENT")
        equal to the projected Excess Costs, if any, within five (5) working
        days after commencement of construction by Landlord. On or prior to the
        Commencement Date, Tenant shall deliver to Landlord the actual Excess
        Costs, minus the Prepayment previously paid. Failure by Tenant to
        timely tender to Landlord the full Prepayment shall permit Landlord to
        stop all work until the Prepayment is received. All sums due Landlord
        under this Section 2.3 shall be considered Rent under the terms of the
        Lease and nonpayment shall constitute a default under the Lease and
        entitle Landlord to any and all remedies specified in the Lease.

2.4     Liens Arising from Excess Costs. Tenant agrees to keep the Premises
        free from any liens arising out of nonpayment of Excess Costs. In the
        event that any such lien is filed and Tenant, within ten (10) days
        following such filing fails to cause same to be released of record by
        payment or posting of a proper bond, Landlord shall have, in addition
        to all other remedies provided herein and by law, the right, but not
        the obligation, to cause the same to be released by such means as it in
        its sole discretion deems proper, including payment of or defense
        against the claim giving rise to such lien. All sums paid by Landlord
        in connection therewith shall constitute Rent under the Lease and a
        demand obligation of Tenant to Landlord and such obligation shall bear
        interest at the rate provided for in Section 15.10 of the Supplemental
        Lease Provisions from the date of payment by Landlord until the date
        paid by Tenant.

3.      DELAYS. Delays in the completion of construction of Tenant's
        Improvements or in obtaining a certificate of occupancy, if
        required by the applicable governmental authority, caused by Tenant,
        Tenant's Contractors (hereinafter defined) or any person, firm or
        corporation employed by Tenant or Tenant's Contractors shall constitute
        "TENANT DELAYS". In the event that Tenant's Improvements are not
        Substantially Complete by the Commencement Date referenced in Item 7 of
        the Basic Lease Provisions, then the Commencement Date referenced in
        Item 7 shall be amended to be the Adjusted Substantial Completion Date
        (hereinafter defined) and the Expiration Date referenced in Item 8 of
        the Basic Lease Provisions shall be adjusted forward by the same number
        of days as is the Commencement Date, provided, however, if the such
        adjusted Expiration Date is a day other than the last day of a calendar
        month, the Expiration Date shall be further adjusted to the last day of
        the applicable calendar month so that the term of the Lease will be the
        term set forth in Item 6 of the Basic Lease Provisions. The Adjusted
        Substantial Completion Date shall be the date Tenant's Improvements are
        Substantially Complete, adjusted backward, however, by one day for each
        day of Tenant Delays, if any. The foregoing adjustments in the
        Commencement Date and the Expiration Date shall be Tenant's sole and
        exclusive remedy in the event Tenant's Improvements are not
        Substantially Complete by the initial Commencement Date set forth in
        Item 8 of the Basic Lease Provisions.

4.      SUBSTANTIAL COMPLETION AND PUNCH LIST. The terms "SUBSTANTIAL
        COMPLETION" and "SUBSTANTIALLY COMPLETE", as applicable, shall mean
        when Tenant's Improvements are sufficiently completed in accordance
        with the Construction Plans so that Tenant can reasonably use the
        Premises for the Permitted Use (as described in Item 11 of the Basic
        Lease Provisions). When Landlord considers Tenant's Improvements to be
        Substantially Complete, Landlord will notify Tenant and within two (2)
        business days thereafter, Landlord's 

                                       3

<PAGE>   60

        representative and Tenant's representative shall conduct a walk-through
        of the Premises and identify any necessary touch-up work, repairs and
        minor completion items as are necessary for final completion of
        Tenant's Improvements. Neither Landlord's representative nor Tenant's
        representative shall unreasonably withhold his agreement on punch list
        items. Landlord will use reasonable efforts to cause the contractor to
        complete all punch list items within thirty (30) days after agreement
        thereon.

5.      TENANT'S CONTRACTORS. If Tenant should desire to enter the Premises or
        authorize its agent to do so prior to the Commencement Date of the
        Lease, to perform approved work not requested of the

        Landlord, Landlord shall permit such entry if:

        (a)     Tenant shall use only such contractors which Landlord shall
                approve in its reasonable discretion and Landlord shall have
                approved the plans to be utilized by Tenant, which approval
                will not be unreasonably withheld; and

        (b)     Tenant, its contractors, workmen, mechanics, engineers, space
                planners or such others as may enter the Premises
                (collectively, "TENANT'S CONTRACTORS"), work in harmony with
                and do not in any way disturb or interfere with Landlord's
                space planners, architects, engineers, contractors, workmen,
                mechanics or other agents or independent contractors in the
                performance of their work (collectively, "LANDLORD'S
                CONTRACTORS"), it being understood and agreed that if entry of
                Tenant or Tenant's Contractors would cause, has caused or is
                causing a material disturbance to Landlord or Landlord's
                Contractors, then Landlord may, with notice, refuse admittance
                to Tenant or Tenant's Contractors causing such disturbance; and

        (c)     Tenant (notwithstanding the first sentence of subsection 7.201
                of the Supplemental Lease Provisions), Tenant's Contractors and
                other agents shall provide Landlord sufficient evidence that
                each is covered under such Worker's Compensation, public
                liability and property damage insurance as Landlord may
                reasonably request for its protection.

        Landlord shall not be liable for any injury, loss or damage to any of
        Tenant's installations or decorations made prior to the Commencement
        Date and not installed by Landlord. Tenant shall indemnify and hold
        harmless Landlord and Landlord's Contractors from and against any and
        all costs, expenses, claims, liabilities and causes of action arising
        out of or in connection with work performed in the Premises by or on
        behalf of Tenant (but excluding work performed by Landlord or
        Landlord's Contractors). Landlord is not responsible for the function
        and maintenance of Tenant's Improvements which are different than
        Landlord's standard improvements at the Property or improvements,
        equipment, cabinets or fixtures not installed by Landlord. Such entry
        by Tenant and Tenant's Contractors pursuant to this Section 5 shall be
        deemed to be under all of the terms, covenants, provisions and
        conditions of the Lease except the covenant to pay Rent.

        for coordination of construction and approval of change orders will be

                                   EXHIBIT F
                            GARAGE PARKING AGREEMENT

    This Exhibit is attached to and a part of that certain Lease Agreement
dated as of ___________________, 199___, executed by and between DALLAS MAIN
CENTER LIMITED PARTNERSHIP, a Delaware limited partnership, and AMERICAN
PHYSICIAN PARTNERS, INC., a Delaware corporation (the "LEASE"). Any capitalized
term not defined herein shall have the meaning assigned to it in the provisions
of the Lease identified as the Basic Lease Provisions or Supplemental Lease
Provisions, as applicable. Landlord and Tenant mutually agree as follows:

1.      PARKING SPACES.

        (a)     So long as the Lease of which this Exhibit is a part shall
                remain in effect, Tenant may rent in the Parking Garage up to a
                number of parking spaces equal to 1 space per square feet of
                rentable area from time to time included in the office use
                portion of the Premises (such spaces, the "PARKING GARAGE
                SPACES"). The number of Parking Garage Spaces to which Tenant
                is entitled in respect of the initial Premises is hereby agreed
                to be eight (8), up to _______ of which Tenant may elect to be
                reserved.

        (b)     Tenant may elect to convert three (3) non-reserved Parking
                Garage Spaces to one (1) parking space in the Executive Parking
                Garage. If Tenant makes such election, Tenant shall have the
                right to reconvert the one parking space in the Executive
                Parking Garage to three (3) non-reserved Parking Spaces in the
                Parking Garage.

2.      PARKING RENTAL. For each Parking Garage Space used by Tenant, Tenant
        shall pay rent equal to the market rent from time to time charged by
        Landlord for parking spaces in the Parking Garage, which market rent is
        currently $110.00 per month per unreserved space and $157.50 per month
        per reserved space. Landlord shall give Tenant at least thirty (30)
        written days' notice of any change in the monthly parking rate for
        Parking Garage Spaces prior to instituting such new monthly rate. All
        payments of rent for parking spaces shall be made (i) at the same time
        as Basic Monthly Rent is due under the Lease and (ii) to Landlord or to
        such persons (for example but without limitation, the manager of the
        Parking Garage) as Landlord may direct from time to time.

3.      PARKING CARDS. Landlord will provide Tenant with an access card for
        each parking space to which Tenant is entitled. Parking cards and
        stickers or any other device or form of identification supplied by
        Landlord shall remain the property of Landlord and shall not be
        transferable. There will be a reasonable replacement charge payable by
        Tenant equal to the amount posted from time to time by Landlord for
        loss of any magnetic parking card or parking sticker issued by
        Landlord.

4.      VALIDATION. Tenant may validate visitor parking, by such method or
        methods as Landlord or the Parking Facility operator may approve, at
        the validation rate from time to time generally applicable to visitor
        parking. Tenant shall pay Landlord for the parking rent generated
        through Tenant's validations within thirty (30) days after receiving a
        written demand therefor. Landlord expressly reserves the right to
        redesignate parking areas and to modify the parking structure for other
        uses or to any extent, but in no event will Tenant's parking spaces be
        reduced by reason of any such redesignation or modification.

5.      DAMAGE TO OR CONDEMNATION OF GARAGE. If Landlord fails or is unable to
        provide any parking space to Tenant in either Parking Facility because
        of damage or condemnation, such failure or inability shall never be
        deemed to be a default by Landlord as to permit Tenant to terminate the
        Lease, either in whole or in part, but Tenant's obligation to pay rent
        for any such parking space which is not provided by Landlord shall be
        abated for so long as Tenant does not have the use of such parking
        space and such abatement shall constitute full settlement of all claims
        that Tenant might otherwise have against Landlord by reason of such
        failure or inability to provide Tenant with such parking space.

6.      RULES AND REGULATIONS. A condition of any parking shall be compliance
        by the parker with Parking Facility rules and regulations, including
        any sticker or other identification system established by Landlord.
        Parking Facility managers or attendants are not authorized to make or
        allow any exceptions to these Rules and Regulations. The following
        rules and regulations are in effect until notice is given to Tenant of
        any change. Landlord reserves the right to modify and/or adopt such
        other reasonable and generally applicable rules and regulations for a
        Parking Facility as it deems necessary for the operation of such
        Parking Facility.

        (a)     Cars must be parked entirely within the stall lines painted on
                the floor.

        (b)     All directional signs and arrows must be observed.

        (c)     The speed limit shall be five (5) miles per hour.

        (d)     Parking is prohibited in areas not striped for parking, aisles,
                areas where "no parking" signs are posted, in cross hatched
                areas and in such other areas as may be designated by Landlord
                or Landlord's agent(s) including, but not limited to, areas
                designated as "Visitor Parking" or reserved spaces not rented
                under this Exhibit.

        (e)     Every parker is required to park and lock his own car. All
                responsibility for damage to cars or persons or loss of
                personal possessions is assumed by the parker.

        (f)     Spaces which are designated for small, intermediate or
                full-sized cars shall be so used. No intermediate or full-size
                cars shall be parked in parking spaces limited to compact cars.

7.      DEFAULT. If Tenant fails to pay the rent for and Parking Garage Space
        as and when due hereunder and such failure continues for a period of
        thirty (30) days after Tenant receives written notice of such failure,
        then, in addition to any other remedies permitted under the Lease,
        Landlord may terminate Tenant's right to use of such Parking Garage
        Space or Spaces, as applicable. In addition, if Tenant has an
        arrangement with any of its employees or other permitted users of its
        Parking Spaces to pay the rent for the Parking Space used by such
        employee or other user, (i) such arrangement will in no way affect
        Tenant's obligation to pay rent for such space as and when due
        hereunder, and (ii) if Landlord does not receive the rent for the space
        used by such party more than two (2) times in any 12-month period, then
        Landlord may prohibit that party from any further use of the Parking
        Facilities. Landlord may refuse to permit any person who violates the
        rules to park in the Parking Facilities and any violation of the rules
        shall subject the car to removal at the car owner's expense. No such
        refusal or removal shall create any liability on Landlord or be deemed
        to interfere with Tenant's right to quiet possession of the Premises.

                             RULES AND REGULATIONS

    This Exhibit is attached to and a part of that certain Lease Agreement
dated as of _____________________, 199____, executed by and between DALLAS MAIN
CENTER LIMITED PARTNERSHIP, a Delaware Limited Partnership and AMERICAN
PHYSICIAN PARTNERS, INC., a Delaware corporation (the "Lease"). Any capitalized
term not defined herein shall have the meaning assigned to it in the provisions
of the Lease identified as the Basic Lease Provisions or Supplemental Lease
Provisions, as applicable.

1.      Except as specifically provided for in this Lease, no sign, placard,
        picture, advertisement, name or notice will be inscribed, displayed or
        printed or affixed on or to any part of the outside or inside of the
        Building or the Premises without the written consent of Landlord first
        having been obtained.

2.      Any directory of the Building provided by Landlord will be exclusively
        for the display of the name and location of tenants in the Building,
        and, subject to Tenant's rights under the Supplemental Lease
        Provisions, Landlord reserves the right to exclude any other names
        therefrom and may limit the number of listings per tenant.

3.      Tenant will not place anything or allow anything to be placed near the
        glass of any window, door, partition or wall which may appear unsightly
        from outside the Premises. No awnings or other projections will be
        attached to the outside walls and roof of the Building without prior
        written consent of Landlord. No curtains, blinds, shades or screens
        will be attached to or hung in or used in connection with any window or
        door of the premises without the prior consent of Landlord.

4.      "NORMAL BUSINESS HOURS" for purposes of Landlord's obligation to
        provide air conditioning (both heating and cooling) will mean 7:00 a.m.

        elevators, stairways, terraces and roof are not for the use of the
        general public, and Landlord will in all cases retain the right to

        the judgment of Landlord, will be prejudicial to the safety, character,
        reputation and interest of the Building and its tenants, provided that
        nothing herein contained will be construed to prevent such access to
        persons with whom Tenant normally deals in the ordinary course of
        business, unless such persons are engaged in illegal activities. No
        tenant and no employee or invitee of any tenant will go upon the roof

        lock it installs on the Premises without charge to Tenant. Landlord
        will make a reasonable charge for any additional keys requested by
        Tenant, and Tenant will not duplicate or obtain keys from any other
        source. Tenant will upon the termination of the Term of this Lease

        into or out of the Building will be done at such time and in such
        manner as Landlord will designate. No furniture, packages, supplies,
        equipment or merchandise will be received in the Building or carried up
        or down in the elevators except between such hours and in such
        elevators that will be designated by Landlord. There will not be used
        in any space or in the public areas of the Building, either by Tenant
        or others, any hand trucks except those equipped with rubber tires and
        side guards.

10.     No tenant will make or permit to be used any unseemly or disturbing
        noises, or disturb or interfere with occupants of this or neighboring
        buildings or leased premises, whether by the use of any musical
        instrument, radio, phonograph, unusual noise or in any other way. No
        tenant will throw anything out of doors or down the passage ways.

11.     Tenant will not use or keep in the Premises or the Building any
        kerosine, gasoline, or any flammable, combustible or explosive fluid,

        other than those supplied or approved by Landlord.

12.     Tenant will see that the windows and doors of the Premises are closed
        and securely locked before leaving the Building. No tenant will permit
        or suffer any windows to be opened in its premises while the air

        conditioning will likewise be carefully shut off so as to prevent waste
        or damage.

        person who, in the judgment of Landlord, is intoxicated or under the
        influence of liquor or drugs, or who will in any manner do any act in
        violation of any of the rules or regulations of the Building.

14.     The requirements of Tenant will be attended to only upon application at
        the office of the Building. Employees of Landlord will not perform any
        work or do anything outside of their regular duties unless under
        special instructions from Landlord, and no employees will admit any
        person (Tenant or otherwise) to any office without specific
        instructions from Landlord.

15.     No tenant will disturb, solicit or canvass any occupant of the
        Building, nor will Tenant permit or cause others to do so, and Tenant
        will cooperate to prevent same by others.

16.     No vending machine or machines of any description will be installed,
        maintained or operated upon the Premises without the written consent of
        Landlord. Tenant will not permit in the Premises any cooking or the use
        of apparatus for the preparation of any food or beverages (except for
        use by Tenant's employees and where the Landlord has approved the
        installation of cooking facilities as part of Tenant's leasehold
        improvements), nor the use of any electrical apparatus likely to cause
        an overload of the electrical circuits.

17.     All persons entering and leaving the Building at any time other than
        during normal business hours will register in the books kept by
        Landlord at or near the night entrance or entrances, and Landlord will
        have the right to prevent any persons entering or leaving the Building
        unless provided with a key to the Premises to which such person seeks
        entrance, and a pass in a form to be approved by Landlord and provided
        at Tenant's expense. Any persons found in the Building at such times
        without such keys or passes will be subject to the surveillance of the
        employees and agents of Landlord. Landlord will be under no
        responsibility for failure to enforce this rule.

18.     Tenant will not use any janitor closets or telephone or electrical
        closets for anything other than their originally intended purposes. In
        the event Tenant will purchase privately owned communications equipment
        for which telephone closets were not installed in connection with
        initial occupancy of Tenant, such equipment will not be installed in
        existing telephone closets.

19.     Tenant's right to have heavy furnishings, equipment and files in the
        Premises will be limited to items weighing less than the load-bearing
        limits of floors within the Premises as established by Landlord. Heavy
        items must be placed in locations approved in advance by Landlord. Upon
        written demand from Landlord, Tenant will promptly remove from the
        Premises any items which, in the judgment of Landlord, constitute a
        structural overload on floors within the Premises. If Landlord approves
        the presence of a heavy item for which reinforcement of the floor or
        other precautionary measures are necessary, Tenant will bear the entire
        cost of such reinforcement or other precautionary measures. If the
        services of a structural engineer are, in the judgment of Landlord,
        necessary to determine the location for and/or precautionary measures
        to be taken in connection with any heavy load, Landlord will engage
        such engineer, but the fees and expenses of such engineer will be paid
        by Tenant upon demand.

                                       3

20.     Tenant will not, without the prior written consent of Landlord, use the
        name or any photograph, drawing or other likeness of the Building for
        any purpose other than as the address of the business to be conducted
        by Tenant in the Premises, nor will Tenant do or permit anything to be
        done in connection with Tenant's business or advertising which, in the
        reasonable judgment of Landlord, might mislead the public as to any
        apparent connection or relationship between Landlord, the Building and
        Tenant.

    In the event there is any conflict between these Rules and Regulations and
the Supplemental Lease Provisions, the Supplemental Lease Provisions will
control.

                                   EXHIBIT H

          ASBESTOS CONTAINING MATERIALS AND OTHER HAZARDOUS SUBSTANCES

    This Exhibit is attached to and a part of that certain Lease Agreement
dated as of January 1, 1996, executed by and between DALLAS MAIN CENTER LIMITED
PARTNERSHIP, a Delaware limited partnership, and AMERICAN PHYSICIAN PARTNERS,
INC., a Delaware corporation ("Lease"). Any capitalized term not defined herein
shall have the meaning assigned to it in the provisions of the Lease identified
as the Basic Lease Provisions or Supplemental Lease Provisions, as applicable.

(a)      A copy of the survey prepared by the independent contractor set forth
         below (the "HAZARDOUS SUBSTANCE SURVEY") is available for Tenant's
         inspection at the office of the Landlord. The purpose of the Hazardous
         Substance Survey is to indicate the presence or absence of hazardous
         or toxic materials (as defined in the Lease) at the Building based on
         the present levels or content of said hazardous or toxic materials as
         presently set by the U.S. Environmental Protection Agency ("EPA") or
         the U.S. Occupational Safety and Health Administration ("OSHA").
         However, Landlord has been advised by the independent contractor that
         any such presence reflected in the Hazardous Substance Survey
         identified below does not violate applicable Laws relating to such
         materials or require removal or controls beyond those already
         implemented by Landlord. Landlord makes no representations or
         warranties whatsoever (express or implied) to Tenant regarding: (x)
         the Hazardous Substance Survey (including, without limitation, the
         contents, accuracy and/or scope thereof) and Landlord has informed
         Tenant that said Hazardous Substance Survey is not a comprehensive
         survey of the Building for all forms of hazardous or toxic materials,
         including, but not limited to asbestos containing materials ("ACM"),
         and cannot be relied upon as a representation that there are no other
         hazardous or toxic materials, including but not limited to asbestos
         and ACM, at the Premises or Building, whether addressed therein or
         not; or (y) the presence or absence of other hazardous or toxic
         materials in, at, or under the Premises or the Building. Tenant (a)
         shall not rely on and has not relied on the Hazardous Substance
         Survey, the same having been provided for informational purposes only
         and (b) acknowledges that Tenant has taken such actions as Tenant
         deems appropriate to fairly evaluate the Premises and has otherwise
         satisfied itself that the Premises are acceptable and suitable from an
         environmental perspective. Tenant shall furnish Landlord with a
         complete and legible copy of any study, report, test, survey or
         investigation performed by or on behalf of Tenant at any time
         involving the Premises and shall fully restore all areas and
         improvements where samples were taken or work performed and repair all
         damage resulting from any of the same.

(b)      Landlord shall, at its sole expense, have the right to conduct such
         other surveys of the Building as Landlord shall elect for the purpose
         of indicating the presence or absence of hazardous or toxic materials
         at the Building based on the present levels or content of said
         hazardous or toxic materials as presently set by the EPA or OSHA. In
         the event that any such additional survey is performed and a copy
         thereof is delivered to Tenant, such additional survey shall become a
         part of the Hazardous Substance Survey.

(c)      In the event that Landlord ever implements an Operations and
         Maintenance Program (the "O&M PROGRAM") with respect to any ACM
         located in the Building, Tenant will be advised of such fact and shall
         be give the opportunity to review the written document setting forth
         the O&M Program. To reduce the risk that the ACM, if any, at the
         Building is improperly disturbed or handled by untrained persons, all
         maintenance, repairs and/or renovations by Tenant to any area of the
         Premises or Building shown on the survey reflecting the existence of
         ACM in the Building must be coordinated with and approved in advance
         by Landlord. Tenant shall insure and hereby agrees that all
         contractors and subcontractors engaged by Tenant agree in writing to
         be bound by and will perform their work subject to the O&M Program.
         Tenant agrees to cooperate with Landlord in all reasonable procedures
         or actions necessary for the conduct of the O&M Program.

(d)      TENANT SHALL INDEMNIFY AND HOLD LANDLORD HARMLESS FROM AND AGAINST ALL
         CLAIMS, ACTIONS, LIABILITIES, DAMAGES, LOSSES, INJURIES OR DEATHS IN
         CONNECTION WITH OR ARISING OUT OF OR FROM ANY INSPECTION, TESTING,
         SAMPLING OR SIMILAR OR DISSIMILAR ACTIVITY CONDUCTED BY TENANT,
         TENANT'S AGENTS OR CONTRACTORS AT THE PREMISES OR THE BUILDING FOR
         HAZARDOUS OR TOXIC MATERIALS, WHETHER UNDER THIS RIDER OR OTHERWISE

                         TENANT'S RIGHT OF OPPORTUNITY
                     (BASIC RENT EQUAL TO FAIR MARKET RENT)

    This Rider is attached to and a part of that certain Lease Agreement dated
as of ______________________, 199___, executed by and between DALLAS MAIN
CENTER LIMITED PARTNERSHIP, a New Jersey corporation and AMERICAN PHYSICIAN
PARTNERS, INC., a Delaware corporation (the "LEASE"). Any capitalized term not
defined herein shall have the meaning assigned to it in the provisions of the
Lease identified as the Basic Lease Provisions or Supplemental Lease
Provisions, as applicable. Landlord and Tenant mutually agree as follows:

A.       Prior to leasing to a third party any of the portion of the
         crosshatched area on the 23rd floor of the Building more particularly
         described in Schedule A attached to this Rider (the "OPPORTUNITY
         EXPANSION SPACE"), Landlord shall deliver to Tenant a written
         statement ("Statement") setting forth (a) the name of a prospective
         tenant interested in all or a portion of the Opportunity Expansion
         Space and (b) Landlord's determination of the Fair Market Rent for the
         applicable Opportunity Expansion Space. Tenant shall have five (5)
         days after receipt of the Statement within which to notify Landlord in
         writing that it elects to lease the applicable Opportunity Expansion
         Space (each such written notice is herein referred to as a "Notice").
         If Tenant elects to lease the applicable Opportunity Expansion Space
         within such five (5) day period, then Tenant's election shall be
         irrevocable and Tenant shall be deemed to have accepted Landlord's
         determination of the Fair Market Rent. Failure by Tenant to notify
         Landlord within such five (5) day period shall be deemed an election
         by Tenant not to lease the applicable Opportunity Expansion Space and
         Landlord shall have the right to lease such space. If Tenant elects
         not to lease the applicable Opportunity Expansion Space or fails to
         elect to lease the applicable Opportunity Expansion Space within such
         5-day period, then Tenant's rights under this Exhibit shall be of no
         further force or effect. Tenant understands and agrees that its rights
         under this Rider with respect to the portion of the Opportunity
         Expansion Space shall be subordinate to any expansion any renewal
         rights granted in a lease executed prior to the date of this Lease.

B.       The applicable Opportunity Expansion Space shall be leased to Tenant
         upon all terms and conditions of this Lease with the following
         exceptions:

         (a)      All Opportunity Expansion Space shall be delivered to Tenant
                  in "as is" condition.

         (b)      Basic Annual Rent for the applicable Opportunity Expansion
                  Space will be equal to the Fair Market Rent, which is hereby
                  defined to mean the then prevailing rents similar to the
                  Basic Annual Rent payable by tenants for premises within the
                  Building of equivalent quality, size, and utility as the
                  applicable Opportunity Expansion Space and leased for a term
                  approximately equal to the then remaining term of the Lease.
                  The Fair Market Rent will take into consideration, and Tenant
                  shall be entitled to, only the tenant inducements (inclusive
                  of the finish allowance) agreed to in the transactions
                  considered by Landlord in determining the Fair Market Rent.

<PAGE>   73

         (c)      the Basic Monthly Rent for the agreed rentable area of the
                  Opportunity Expansion Space will be equal to one-twelfth
                  (1/12th) of the Basic Annual Rent for the applicable
                  Opportunity Expansion Space.

         (d)      The Operating Expenses Stop and Real Estate Taxes Stop for
                  the entire Premises shall each be recalculated based on the
                  rentable area of the Premises following the addition of the
                  applicable Opportunity Expansion Space to the Premises.

         (e)      The dates for submission of the initial space plan and
                  construction plans shall be agreed to by Landlord and Tenant
                  within five (5) days after Tenant elects to lease the
                  applicable Opportunity Expansion Space.

         (f)      The rent commencement date with respect to the applicable
                  Opportunity Expansion Space shall be the earlier to occur of
                  (x) substantial completion of the tenant improvements to be
                  installed in such space and (y) thirty days (30) days after
                  the date Landlord delivers to Tenant the initial space plan
                  for the applicable Opportunity Expansion Space (the date
                  determined pursuant to this clause (y), the "SCHEDULED RENT
                  COMMENCEMENT DATE"), provided, however, such Scheduled Rent
                  Commencement Date shall be subject to adjustment to the same
                  extent that the Commencement Date for the initial Premises is
                  subject to adjustment under Section 3 of the Work Letter.

         (g)      Tenant shall have no right to occupy any portion of the
                  Opportunity Expansion Space prior to the applicable Scheduled
                  Rent Commencement Date and in no event shall Tenant occupy
                  any Opportunity Expansion Space prior to (i) Substantial
                  Completion of the leasehold improvements being constructed in
                  the applicable Opportunity Expansion Space, (ii) issuance of
                  a certificate of completion or other document or permit
                  issued by the applicable governmental authority authorizing
                  Tenant's occupancy of the applicable Opportunity Expansion
                  Space and (iii) Landlord's receipt of an Acceptance of
                  Premises Memorandum covering the applicable Opportunity
                  Expansion Space executed by Tenant.

C.       Within fifteen (15) days after Landlord's receipt of a Notice, Tenant
         and Landlord will enter into a work letter substantially in the form
         of Exhibit D attached to the Lease, provided that such form shall be
         amended to (i) set forth provisions for preparation of constrution
         drawings and approval dates thereof, (ii) amend the finish allowance
         to be the amount of finish allowance, if any, considered in
         calculating the Fair Market Rent and (iii) provide for such other
         matters as are necessary to reflect the agreements of the parties with
         respect to the finish out of the applicable Opportunity Expansion
         Space. Pursuant to the work letter, Landlord shall construct or cause
         to be constructed improvements in the applicable Opportunity Expansion
         Space in substantial accordance with construction plans agreed to by
         Landlord and Tenant.

D.       Upon substantial completion of the applicable Opportunity Expansion
         Space improvements, Landlord and Tenant shall execute an Acceptance of
         Premises Memorandum in substantially the form of Exhibit E attached to
         the Lease. If Tenant occupies any Opportunity Expansion Space without
         executing the Acceptance of Premises Memorandum, Tenant shall be
         deemed to have accepted such Opportunity Expansion Space for all
         purposes.

         Operating Costs and Energy Costs shall be adjusted to include the

         3.      Exhibit I.  Landlord and Tenant acknowledge and agree that

benefit of and be binding upon the parties hereto and their respective heirs,
successors in interest and legal representatives.  The terms and conditions of
this Amendment may not be modified, amended, altered or otherwise affected
except by instrument in writing executed by Landlord and Tenant.  THIS
AMENDMENT REPRESENTS THE FINAL AGREEMENT BETWEEN LANDLORD AND TENANT WITH
RESPECT TO THE AMENDMENT OF THE LEASE, AND MAY NOT BE CONTRADICTED BY EVIDENCE

TENANT.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN LANDLORD AND TENANT.

         7.      Counterparts.    This Amendment may be executed in multiple

which constitutes collectively but one instrument; but in making proof of this
Amendment, it shall not be necessary to produce or account for more than one
(1) counterpart.

         CREDIT AGREEMENT, dated ________ __, 1997 among AMERICAN PHYSICIAN
PARTNERS, INC., a Delaware corporation ("Borrower"), and GENERAL ELECTRIC
CAPITAL CORPORATION, a New York corporation (in its individual capacity, "GE
Capital"), for itself, as Lender, and as Agent for Lenders, and the other
Lenders signatory hereto from time to time.

                                    RECITALS

         WHEREAS, Borrower desires that Lenders extend revolving credit
facilities to Borrower of up to One Hundred Fifteen Million Dollars
($115,000,000.00) in the aggregate for the purpose of refinancing certain
indebtedness of Borrower and the seven (7) radiology practices to be acquired
by the Borrower on the date hereof and to provide working capital financing for
Borrower and funds for other general corporate purposes of Borrower; and for
these purposes, Lenders are willing to make certain loans and other extensions
of credit to Borrower of up to such amount upon the terms and conditions set
forth herein; and

         WHEREAS, Borrower desires to secure all of its obligations under the
Loan Documents by pledging to Agent, for the benefit of Agent and Lenders, all
of the issued and outstanding capital stock of Borrower's Subsidiaries and all
the Borrower's or any Subsidiary's right, title and interest in the equity of
any partnership, joint venture or other business organization and all
intercompany notes, and granting to Agent for the benefit of Agent and Lenders
a security interest in all Service Agreements; and

         WHEREAS, capitalized terms used in this Agreement shall have the
meanings ascribed to them in Annex A. All Annexes, Disclosure Schedules,
Exhibits and other attachments (collectively, "Appendices") hereto, or
expressly identified to this Agreement, are incorporated herein by reference,
and taken together, shall constitute but a single agreement. These Recitals
shall be construed as part of the Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants hereinafter contained, and for other good and valuable consideration,
the parties hereto agree as follows:

1. AMOUNT AND TERMS OF CREDIT

         1.1 REVOLVING CREDIT FACILITY. (a) Subject to the terms and conditions
hereof, each Lender agrees to make available from time to time until the
Commitment Termination Date its Pro Rata Share of advances (each, a "Revolving
Credit Advance"). The Pro Rata Share of the Revolving Loan of any Lender shall
not at any time exceed its separate Revolving Loan Commitment. The obligations
of each Lender hereunder shall be several and not joint. The aggregate amount
of Revolving Credit Advances outstanding shall not exceed at any time the
lesser of (A) the Maximum Amount and (B) the Revolving Credit Availability, in
each case less the sum of the Letter of Credit Obligations and the Swing Line
Loan outstanding at such time ("Borrowing



                                      -1-
<PAGE>   7


Availability"). Until the Availability Termination Date, Borrower may from time
to time borrow, repay and reborrow under this Section 1.1. Each Revolving
Credit Advance shall be made on notice by Borrower to the representative of
Agent identified on Schedule 1.1 at the address specified thereon. Those
notices must be given no later than (1) 2:00 p.m. (New York time) on the
Business Day prior to the date of the proposed Revolving Credit Advance, in the
case of an Index Rate Loan, or (2) 1:00 p.m. (New York time) on the date which
is three (3) Business Days prior to the proposed Revolving Credit Advance, in
the case of a LIBOR Loan. Each such notice (a "Notice of Revolving Credit
Advance") must be given in writing (by telecopy or overnight courier)
substantially in the form of Exhibit 1.1(a), and shall include the information
required in such Exhibit and such other information as may be required by
Agent. If Borrower desires to have the Revolving Credit Advances bear interest
by reference to a LIBOR Rate, it must comply with Section 1.5(e).

         (b) Borrower shall execute and deliver to each Lender a note to
evidence the Revolving Loan Commitment of that Lender. Each note shall be in
the principal amount of the Revolving Loan Commitment of the applicable Lender,
dated the Closing Date and substantially in the form of Exhibit 1.1(b) (each a
"Revolving Note" and, collectively, the "Revolving Notes"). Each Revolving Note
shall represent the obligation of Borrower to pay the amount of each Lender's
Revolving Loan Commitment or, if less, the applicable Lender's Pro Rata Share
of the aggregate unpaid principal amount of all Revolving Credit Advances to
Borrower together with interest thereon as prescribed in Section 1.5. The
entire unpaid balance of the Revolving Loan and all other noncontingent
Obligations shall be immediately due and payable in full in immediately
available funds on the Commitment Termination Date.

         (c) SWING LINE FACILITY. (i) Agent shall notify the Swing Line Lender
upon Agent's receipt of any Notice of Revolving Credit Advance. Subject to the
terms and conditions hereof, the Swing Line Lender shall make available from
time to time until the Availability Termination Date advances (each, a "Swing
Line Advance") in accordance with any such notice to the extent that such
notice requests the Borrower to make such Advance as a Swing Line Advance. The
aggregate amount of Swing Line Advances outstanding shall not exceed the lesser
of (A) the Swing Line Commitment and (B) the Revolving Credit Availability less
the outstanding balance of the Revolving Loan and the Letter of Credit
Obligations at such time ("Swing Line Availability"). Until the Availability
Termination Date, Borrower may from time to time borrow, repay and reborrow
under this Section 1.1(c). Each Swing Line Advance shall be made pursuant to a
Notice of Revolving Credit Advance delivered by Borrower to Agent in accordance
with Section 1.1(a) which requests a Swing Line Advance. Those notices must be
given no later than 12:00 noon (New York time) on the Business Day of the
proposed Swing Line Advance. Notwithstanding any other provision of this
Agreement or the other Loan Documents, the Swing Line Loan shall constitute an
Index Rate Loan. Borrower shall repay the aggregate outstanding principal
amount of the Swing Line Loan (i) in the absence of the occurrence and
continuance of an Event of Default, within one Business Day following the Swing
Line Lender's demand therefor, and (ii) during the occurrence and continuance
of an Event of Default, upon demand therefor by the Swing Line Lender.



                                      -2-
<PAGE>   8


         (ii) Borrower shall execute and deliver to the Swing Line Lender a
promissory note to evidence the Swing Line Commitment. Such note shall be in
the principal amount of the Swing Line Commitment of the Swing Line Lender,
dated the Closing Date and substantially in the form of Exhibit 1.1(c)(ii) (the
"Swing Line Note"). The Swing Line Note shall represent the obligation of
Borrower to pay the amount of the Swing Line Commitment or, if less, the
aggregate unpaid principal amount of all Swing Line Advances made to Borrower
together with interest thereon as prescribed in Section 1.5. The entire unpaid
balance of the Swing Line Loan and all other non-contingent Obligations shall
be immediately due and payable in full in immediately available funds on the
Commitment Termination Date if not sooner paid in full.

         (iii) REFUNDING OF SWING LINE LOANS. The Swing Line Lender, at any
time and from time to time in its sole and absolute discretion, may on behalf
of Borrower (and Borrower hereby irrevocably authorizes the Swing Line Lender
to so act on its behalf) request each Revolving Lender (including the Swing
Line Lender) to make a Revolving Credit Advance to Borrower (which shall be an
Index Rate Loan) in an amount equal to such Revolving Lender's Pro Rata Share
of the principal amount of the Swing Line Loan (the "Refunded Swing Line Loan")
outstanding on the date such notice is given. Unless any of the events
described in Sections 8.1(h) or 8.1(i) shall have occurred (in which event the
procedures of Section 1.1(c)(iv) shall apply) and regardless of whether the
conditions precedent set forth in this Agreement to the making of a Revolving
Credit Advance are then satisfied, each Revolving Lender shall disburse
directly to Agent, its Pro Rata Share of a Revolving Credit Advance on behalf
of the Swing Line Lender, prior to 3:00 p.m. (New York time), in immediately
available funds on the Business Day next succeeding the date such notice is
given. The proceeds of such Revolving Credit Advances shall be immediately paid
to the Swing Line Lender and applied to repay the Refunded Swing Line Loan.

         (iv) PARTICIPATION IN SWING LINE LOANS. If, prior to refunding a Swing
Line Loan with a Revolving Credit Advance pursuant to Section 1.1(c)(iii), one
of the events described in Sections 8.1(h) or 8.1(i) shall have occurred, then,
subject to the provisions of Section 1.1(c)(v) below, each Revolving Lender
will, on the date such Revolving Credit Advance was to have been made for the
benefit of Borrower, purchase from the Swing Line Lender an undivided
participation interest in the Swing Line Loan in an amount equal to its Pro
Rata Share of such Swing Line Loan. Upon request, each Revolving Lender will
promptly transfer to the Swing Line Lender, in immediately available funds, the
amount of its participation and upon receipt thereof the Swing Line Lender will
deliver to such Revolving Lender a Swing Line Loan Participation Certificate,
substantially the form of Exhibit 1.1(c)(iv), dated the date of receipt of such
funds and in such amount.

         (v) REVOLVING LENDERS' OBLIGATIONS UNCONDITIONAL. Each Revolving
Lender's obligation to make Revolving Credit Advances in accordance with
Section 1.1(c)(iii) and to purchase participating interests in accordance with
Section 1.1(c)(iv) shall be absolute and unconditional and shall not be
affected by any circumstance, including (A) any setoff, counterclaim,
recoupment, defense or other right which such Revolving Lender



                                      -3-
<PAGE>   9


may have against the Swing Line Lender, Borrower or any other Person for any
reason whatsoever; (B) the occurrence or continuance of any Default or Event of
Default; (C) any inability of Borrower to satisfy the conditions precedent to
borrowing set forth in this Agreement on the date upon which such participating
interest is to be purchased or (D) any other circumstance, happening or event
whatsoever, whether or not similar to any of the foregoing. If any Revolving
Lender does not make available to Agent or the Swing Line Lender, as
applicable, the amount required pursuant to Section 1.1(c)(iii) or 1.1(c)(iv),
as the case may be, the Swing Line Lender shall be entitled to recover such
amount on demand from such Revolving Lender, together with interest thereon for
each day from the date of non-payment until such amount is paid in full at the
Federal Funds Rate for the first two Business Days and at the Index Rate
thereafter.

         1.2 LETTERS OF CREDIT. Subject to and in accordance with the terms and
conditions contained herein and in Annex B, Borrower shall have the right to
request, and Lenders agree to incur, or purchase participations in, Letter of
Credit Obligations in respect of Borrower.

         1.3 PREPAYMENTS AND COMMITMENT REDUCTIONS.

         (a) VOLUNTARY COMMITMENT REDUCTIONS. Borrower may at any time on at
least fifteen (15) Business Days' prior written notice to Agent voluntarily and
permanently reduce or terminate the Revolving Loan Commitment; provided that
(A) any such partial reduction shall be in a minimum amount of $5,000,000 and
integral multiples of $250,000 in excess of such amount and (B) the Revolving
Loan Commitment shall not be reduced to an amount less than the L/C Sublimit
plus the Swing Line Commitment. Upon the effective date of any such termination
all Advances and other Obligations shall be immediately due and payable in
full. Any such voluntary reduction or termination of the Revolving Loan
Commitment must be accompanied by the payment, if any, required by Section
1.3(b)(i) below, plus any LIBOR funding breakage costs resulting therefrom in
accordance with Section 1.10(b). Each notice of partial reduction shall
designate whether such reduction shall apply to reduce the L/C Sublimit or the
Swing Line Commitment. Upon any such reduction or termination of the Revolving
Loan Commitment, Borrower's right to request Revolving Credit Advances, or
request that Letter of Credit Obligations be incurred on its behalf, or request
Swing Line Advances, shall simultaneously be permanently reduced or terminated,
as the case may be. Any voluntary prepayment made after the Availability
Termination Date shall be deemed a voluntary commitment reduction pursuant to
this Section and such reduction shall be applied against installments due under
Section 1.3(b)(iv) pro rata.

         (b) Mandatory Prepayments and Commitment Reductions. (i) If at any
time the outstanding balance of the Revolving Loan exceeds the lesser of (A)
the Maximum Amount and (B) the Revolving Credit Availability, less, in each
case, the outstanding Swing Line Loan at such time, Borrower shall



                                      -4-
<PAGE>   10


immediately repay the outstanding Revolving Credit Advances to the extent
required to eliminate such excess. If any such excess remains after repayment
in full of the aggregate outstanding Revolving Credit Advances, Borrower shall
provide cash collateral for the Letter of Credit Obligations in the manner set
forth in Annex B to the extent required to eliminate such excess.

         (ii) (A) Immediately upon receipt by any Credit Party of proceeds of
any asset disposition (including condemnation proceeds, but excluding proceeds
of asset dispositions permitted by Section 6.8(a) or (b)), Borrower shall
prepay the Loans in an amount equal to the amount by which all such proceeds,
net of (1) commissions and other reasonable and customary transaction costs,
fees and expenses properly attributable to such transaction and payable by
Borrower in connection therewith (in each case, paid to non- Affiliates), (2)
transfer taxes, (3) amounts payable to holders of senior Liens (to the extent
such Liens constitute Permitted Encumbrances hereunder), if any, and (4) an
appropriate reserve for income taxes in accordance with GAAP in connection
therewith, exceeds one million five hundred thousand dollars ($1,500,000) in
any Fiscal Year; provided that such prepayments shall be made in increments of
$100,000 only (any amount not paid as a result of this requirement shall be
accumulated and paid when the aggregate amount of such accumulation shall meet
the required prepayment increment). For the purposes of this Section
1.3(b)(ii)(A) the Credit Parties shall not be deemed to have received proceeds
of any disposition permitted pursuant to Section 6.8(c) or (d) to the extent
that such proceeds are redeployed to replace the asset disposed of in the
manner and within the time period provided in such sections. To the extent that
such proceeds are not so redeployed within such time period, such proceeds
shall be deemed received by the Credit Parties upon the expiration of such
period. Any such prepayment shall be applied in accordance with clause (c)
below.

         (B) Immediately upon receipt by any Credit Party of proceeds of any
sale of Stock or of all or substantially all of the assets of any Subsidiary or
Permitted Joint Venture in accordance with Section 6.8(e), the Borrower shall
prepay the Loans in an amount equal to all such proceeds, net of: (i)
commissions and other reasonable and customary transaction costs, fees and
expenses properly attributable to such transaction and payable by Borrower in
connection therewith (in each case, paid to non-Affiliates), (ii) transfer
taxes, (iii) amounts payable to holders of senior Liens (to the extent such
Liens constitute Permitted Encumbrances hereunder), if any, and (iv) an
appropriate reserve for income taxes in accordance with GAAP in connection
therewith.

         (iii) If Borrower issues Stock or any Indebtedness, other than Stock
or Indebtedness issued as a part of the consideration for a Permitted
Acquisition and other than Indebtedness permitted pursuant to Section 6.3, then
no later than the Business Day following the date of receipt of the proceeds
thereof, Borrower shall prepay the Revolving Loan in an amount equal to all
such proceeds, net of underwriting discounts and commissions and other
reasonable costs paid to non-Affiliates in connection therewith. Any such
prepayment shall be applied in accordance with clause (c) below.

         (iv) Commencing on September 30, 2000 (the "Amortization Commencement
Date") and on the last business day of each Fiscal Quarter thereafter until the
Commitment Termination Date, the Borrower shall repay the Revolving Loan
outstanding in quarterly installments equal to the lesser of: (x) the
percentage of the aggregate principal amount of the Revolving Loan outstanding
on the Amortization Commencement Date set forth opposite the period in which
such fiscal quarter ends below and (y) the amount of Revolving Loan outstanding
concurrent on the date of such installment:

                       and thereafter
</TABLE>

         (v) Notwithstanding anything else in this Agreement to the contrary,
all Obligations shall be due and payable, and all Letters of Credit (or standby
guarantees therefor) shall be cancelled or returned or cash collateralized in
accordance with Annex B, on the Commitment Termination Date.

         (c) APPLICATION OF CERTAIN MANDATORY PREPAYMENTS. Any prepayments made
by Borrower pursuant to clause (b)(ii) or (b)(iii) above shall be applied as
follows: first, to Fees and reimbursable expenses of Agent then due and payable
pursuant to any of the Loan Documents; second, to interest then due and payable
on the Swing Line Loan; third, to the principal balance of the Swing Line Loan
until the same shall have been repaid in full; fourth, to interest then due and
payable on the Revolving Credit Advances; fifth, to the outstanding principal
balance of Revolving Credit Advances until the same shall have been paid in
full; and sixth, to any Letter of Credit Obligations or to provide cash
collateral therefor in the manner set forth in Annex B, until all such Letter
of Credit Obligations have been fully cash collateralized or secured in the
manner set forth in Annex B.

         (d) COMMITMENT REDUCTIONS. The Revolving Loan Commitment shall be
permanently reduced (i) to the amount of the aggregate outstanding principal
amount of the Revolving Loan on the Availability Termination Date, and (ii) by
the amount of any payment or prepayment pursuant to Sections 1.3(b)(ii), (iii)
or (iv) made subsequent to the Availability Termination Date. Any prepayments
described in clause (ii) of this subsection (d) that permanently reduce the
Revolving Loan Commitment shall be applied against installments due pursuant to
Section 1.3(b)(iv) in inverse order of the occurrence thereof. The Swing Line
Commitment shall terminate on the Availability Termination Date.



                                      -6-
<PAGE>   12


         (e) Nothing in this Section 1.3 shall be construed to constitute
Agent's or any Lender's consent to any transaction referred to in clauses
(b)(ii) or (b)(iii) above which is not permitted by other provisions of this
Agreement or the other Loan Documents.

         1.4 USE OF PROCEEDS. Borrower shall utilize the proceeds of the
Revolving Loan and the Swing Line Loan solely for funding Permitted
Acquisitions, the Refinancing (and to pay any related transaction expenses),
and for the financing of Borrower's ordinary working capital, Capital
Expenditures and for other lawful purposes. Disclosure Schedule (1.4) contains
a description of Borrower's sources and uses of funds as of the Closing Date,
including Revolving Credit Advances and Letter of Credit Obligations to be made
or incurred on that date, and a funds flow memorandum detailing how funds from
each source are to be transferred to particular uses.

         1.5 INTEREST AND APPLICABLE MARGINS. (a) Borrower shall pay interest
to Agent, (i) for the ratable benefit of Lenders in accordance with the
Revolving Credit Advances being made by each Lender, in arrears on each
applicable Interest Payment Date, at the Index Rate plus the Applicable
Revolver Index Margin per annum or, at the election of Borrower, the applicable
LIBOR Rate plus the Applicable Revolver LIBOR Margin per annum, on the
aggregate Revolving Credit Advances outstanding from time to time, (ii) for the
benefit of the Swing Line Lender with respect to the Swing Line Loan, at the
Index Rate plus the Applicable Revolver Index Margin per annum, (A) in the
absence of the occurrence and continuance of an Event of Default, within one
Business Day following the Swing Line Lender's demand therefor, and (B) during
the occurrence and continuance of an Event of Default, upon demand therefor by
the Swing Line Lender.

         The Applicable Revolver Index Margin, Applicable Revolver LIBOR Margin
and the Applicable L/C Margin will be 0.375%, 1.375% and 1.375% per annum,
respectively, as of the Closing Date. Commencing with the date that the
Borrower delivers consolidated quarterly Financial Statements for the first
Fiscal Quarter that ends at least six (6) months after the Closing Date, the
Applicable Margins will be adjusted (up or down) prospectively on a quarterly
basis based upon Borrower and its Restricted Subsidiaries' Senior Debt Leverage
Ratio for the applicable test period ended on the last day of such Fiscal
Quarter. Adjustments in Applicable Margins will be determined by reference to
the following grids:

</TABLE>

         All adjustments in the Applicable Margins based on the foregoing ratio
will be implemented quarterly on a prospective basis, for each calendar month
commencing at least five (5) days after the date of delivery to Lenders of the
quarterly unaudited or annual audited (as applicable) Financial Statements of
Borrower evidencing the need for an adjustment. Concurrently with the delivery
of those Financial Statements, Borrower shall deliver to Agent and Lenders a
certificate, signed by its chief financial officer, setting forth in reasonable
detail the basis for the continuance of, or any change in, the Applicable
Margins. If an Event of Default shall have occurred and be continuing, at the
election of the Agent (or upon the written request of the Requisite Lenders),
the Applicable Margins shall immediately increase to the highest level set
forth on the foregoing grid effective as of the initial date of such Event of
Default until the date on which such Event of Default is waived or cured.

         (b) If any payment on any Obligation becomes due and payable on a day
other than a Business Day, the maturity thereof will be extended to the next
succeeding Business Day (except as set forth in the definition of LIBOR Period)
and, with respect to payments of principal, interest thereon shall be payable
at the then applicable rate during such extension.

         (c) All computations of Fees calculated on a per annum basis and
interest shall be made by Agent on the basis of a three hundred and sixty (360)
day year, in each case for the actual number of days occurring in the period
for which such interest and Fees are payable. The Index Rate shall be
determined each day based upon the Index Rate as in effect each day. Each
determination by Agent of an interest rate hereunder shall be conclusive,
absent manifest error.

         (d) So long as an Event of Default described in Section 8.1(a)
resulting from the failure to pay principal, interest or letter of credit fees
shall have occurred and be continuing (a "Payment Default"), and at the
election of Agent (or upon the written request of Requisite Lenders) confirmed
by written notice from Agent to Borrower, the interest rates applicable to the
Obligations and the Letter of Credit Fees shall be increased by two percentage
points (2%) per annum above the rates of interest or the rate of such Fees
("Default Rate"), and all outstanding Obligations shall bear interest at the
Default Rate applicable to such Obligations. Interest and Letter of Credit Fees
at the Default Rate shall accrue from the initial date of such Event of Default
until the date on which such Event of Default is cured or waived and shall be
payable upon demand.



                                      -8-
<PAGE>   14


         (e) So long as no Default or Event of Default shall have occurred and
be continuing, and subject to the additional conditions precedent set forth in
Section 2.2, Borrower shall have the option to: (i) request that any Revolving
Credit Advances be made as a LIBOR Loan, (ii) convert at any time all or any
part of outstanding Revolving Credit Advances from Index Rate Loans to LIBOR
Loans, (iii) convert any LIBOR Loan to an Index Rate Loan, subject to payment
of LIBOR breakage costs in accordance with Section 1.10(b) if such conversion
is made prior to the expiration of the LIBOR Period applicable thereto, or (iv)
continue all or any portion of any Revolving Credit Advances as a LIBOR Loan
upon the expiration of the applicable LIBOR Period and the succeeding LIBOR
Period of that continued LIBOR Loan shall commence on the last day of the LIBOR
Period of the Loan to be continued. The aggregate amount of Revolving Credit
Advances to be made or continued as, or converted into, a LIBOR Loan must be in
a minimum amount of $1,000,000 and integral multiples of $250,000 in excess of
such amount. Any such election must be made by 1:00 p.m. (New York time) on the
third (3rd) Business Day prior to (1) the date of any proposed Advance which is
to be made as part of a LIBOR Loan, (2) the end of each LIBOR Period with
respect to any LIBOR Loans to be continued as such, or (3) the date on which
Borrower wishes to convert any Index Rate Loan to a LIBOR Loan. If no election
is received with respect to a LIBOR Loan by 1:00 p.m. (New York time) on the
third (3rd) Business Day prior to the end of the LIBOR Period with respect
thereto (or if a Default or an Event of Default shall have occurred and be
continuing or the additional conditions precedent set forth in Section 2.2
shall not have been satisfied), that LIBOR Loan shall be converted to an Index
Rate Loan at the end of its LIBOR Period. Borrower must make such election by
notice to Agent in writing, by telecopy or overnight courier. In the case of
any conversion or continuation, such election must be made pursuant to a
written notice (a "Notice of Conversion/Continuation") in the form of Exhibit
1.5(e).

         (f) Notwithstanding anything to the contrary set forth in this Section
1.5, if a court of competent jurisdiction determines in a final order that the
rate of interest payable hereunder exceeds the highest rate of interest
permissible under law (the "Maximum Lawful Rate"), then so long as the Maximum
Lawful Rate would be so exceeded, the rate of interest payable hereunder shall
be equal to the Maximum Lawful Rate; PROVIDED, HOWEVER, that if at any time
thereafter the rate of interest payable hereunder is less than the Maximum
Lawful Rate, Borrower shall continue to pay interest hereunder at the Maximum
Lawful Rate until such time as the total interest received by Agent, on behalf
of Lenders, is equal to the total interest which would have been received had
the interest rate payable hereunder been (but for the operation of this
paragraph) the interest rate payable since the Closing Date as otherwise
provided in this Agreement. Thereafter, interest hereunder shall be paid at the
rate(s) of interest and in the manner provided in



                                      -9-
<PAGE>   15


Sections 1.5(a) through (e) above, unless and until the rate of interest again
exceeds the Maximum Lawful Rate, and at that time this paragraph shall again
apply. In no event shall the total interest received by any Lender pursuant to
the terms hereof exceed the amount which such Lender could lawfully have
received had the interest due hereunder been calculated for the full term
hereof at the Maximum Lawful Rate. If the Maximum Lawful Rate is calculated
pursuant to this paragraph, such interest shall be calculated at a daily rate
equal to the Maximum Lawful Rate divided by the number of days in the year in
which such calculation is made. If, notwithstanding the provisions of this
Section 1.5(f), a court of competent jurisdiction shall finally determine that
a Lender has received interest hereunder in excess of the Maximum Lawful Rate,
Agent shall, to the extent permitted by applicable law, promptly apply such
excess in the order specified in Section 1.8 and thereafter shall refund any
excess to Borrower or as a court of competent jurisdiction may otherwise order.

         1.6 FEES. (a) Borrower shall pay to GE Capital, individually, the Fees
specified in that certain fee letter dated June 16, 1997, between Borrower and
GE Capital (the "GE Capital Fee Letter"), at the times specified for payment
therein.

         (b) As additional compensation for the Lenders, Borrower agrees to pay
to Agent, for the ratable benefit of such Lenders, in arrears, on the first
Business Day of each Fiscal Quarter that occurs following the Closing Date and
prior to the Availability Termination Date and on the Availability Termination
Date, for each day from and including the Execution Date, to but excluding the
Availability Termination Date, a fee for the Lenders making available the
Revolving Credit Commitment in an amount equal to one quarter of one percent
(.25%) per annum (calculated on the basis of a 360 day year for actual days
elapsed) of the difference between (x) the Maximum Amount (as in effect from
time to time) and (y) the average for the period of the daily closing principal
balance of the Revolving Loan outstanding during the period for which such fee
is due.

         1.7 RECEIPT OF PAYMENTS. Borrower shall make each payment under this
Agreement not later than 12:00 noon (New York time) on the day when due in
immediately available funds in Dollars to the Collection Account. For purposes
of computing interest and Fees and determining Borrowing Availability or Net
Borrowing Availability as of any date, all payments shall be deemed received on
the day of receipt of immediately available funds therefor in the Collection
Account prior to 12:00 noon New York time. Payments received after 12:00 noon
New York time on any Business Day shall be deemed to have been received on the
following Business Day.

         1.8 APPLICATION AND ALLOCATION OF PAYMENTS. So long as no Event of
Default shall have occurred and be continuing, (i) payments matching specific
scheduled payments then due shall be applied to those scheduled payments; (ii)
voluntary prepayments shall be applied as determined by Borrower, subject to
the last sentence of Section 1.3(a); and (iii) mandatory prepayments shall be
applied as set forth in Section 1.3. As to each other payment, and as to all
payments made when an Event of Default shall have



                                      -10-
<PAGE>   16


occurred and be continuing or following the Commitment Termination Date,
Borrower hereby irrevocably waives the right to direct the application of any
and all payments received from or on behalf of Borrower, and Borrower hereby
irrevocably agrees that Agent shall have the continuing exclusive right to
apply any and all such payments against the Obligations as Agent may deem
advisable notwithstanding any previous entry by Agent in the Loan Account or
any other books and records. In the absence of a specific determination by
Agent with respect thereto, and except as provided above, payments shall be
applied to amounts then due and payable in the following order: (1) to Fees and
Agent's expenses reimbursable hereunder; (2) to interest on the Swing Line
Loan; (3) to principal payments on the Swing Line Loan; (4) to interest on the
Revolving Credit Advances and Letter of Credit Fees; (5) to principal payments
on the Revolving Credit Advances and to provide cash collateral for Letter of
Credit Obligations in the manner described in Annex B, ratably to the
aggregate, combined principal balance of the Advances and outstanding Letter of
Credit Obligations; and (6) to all other Obligations including expenses of
Lenders to the extent reimbursable under Section 11.3.

         1.9 LOAN ACCOUNT AND ACCOUNTING. Agent shall maintain a loan account
(the "Loan Account") on its books to record: (a) all Advances and Letter of
Credit Obligations, (b) all payments made by Borrower, and (c) all other debits
and credits as provided in this Agreement with respect to the Loans or any
other Obligations. All entries in the Loan Account shall be made in accordance
with Agent's customary accounting practices as in effect from time to time. The
balance in the Loan Account, as recorded on Agent's most recent printout or
other written statement, shall be presumptive evidence of the amounts due and
owing to Agent and Lenders by Borrower; provided that any failure to so record
or any error in so recording shall not limit or otherwise affect Borrower's
duty to pay the Obligations. Agent shall render to Borrower a monthly
accounting of transactions with respect to the Revolving Loan setting forth the
balance of the Loan Account. Unless Borrower notifies Agent in writing of any
objection to any such accounting (specifically describing the basis for such
objection), within thirty (30) days after the Borrower's receipt thereof, each
and every such accounting shall (absent manifest error) be deemed final,
binding and conclusive upon Borrower in all respects as to all matters
reflected therein. Only those items expressly objected to in such notice shall
be deemed to be disputed by Borrower.

         1.10 INDEMNITY. (a) Whether or not any Advance is ever made or Letter
of Credit ever issued hereunder, Borrower shall indemnify and hold harmless
each of Agent, the L/C Issuers, Lenders and their respective Affiliates, and
each such Person's respective officers, directors, employees, attorneys, agents
and representatives (each, an "Indemnified Person"), from and against any and
all suits, actions, proceedings, claims, damages, losses, liabilities and
expenses (including attorneys' fees and disbursements and other costs of
investigation or defense, including those incurred upon any appeal) which may
be instituted or asserted against or incurred by any such Indemnified Person as
the result of credit having been extended, suspended or terminated under this
Agreement and the other Loan Documents or the administration of such credit, or
the execution, delivery or performance of the Loan Documents, or otherwise in
connection with or arising out of the transactions contemplated hereunder



                                      -11-
<PAGE>   17


and thereunder (including, without limitation, the IPO, any Acquisition or
Permitted Acquisition) and any actions or failures to act in connection
therewith, including any and all Environmental Liabilities and legal costs and
expenses arising out of or incurred in connection with disputes between or
among any parties to any of the Loan Documents (collectively, "Indemnified
Liabilities"); provided, that Borrower shall not be liable for any
indemnification to an Indemnified Person to the extent that any such suit,
action, proceeding, claim, damage, loss, liability or expense results from that
Indemnified Person's gross negligence or willful misconduct, as finally
determined by a court of competent jurisdiction. NO INDEMNIFIED PERSON SHALL BE
RESPONSIBLE OR LIABLE TO ANY OTHER PARTY TO ANY LOAN DOCUMENT, ANY SUCCESSOR,
ASSIGNEE OR THIRD PARTY BENEFICIARY OF SUCH PERSON OR ANY OTHER PERSON
ASSERTING CLAIMS DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE,
EXEMPLARY OR CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT
HAVING BEEN EXTENDED, SUSPENDED OR TERMINATED UNDER ANY LOAN DOCUMENT OR AS A
RESULT OF ANY OTHER TRANSACTION CONTEMPLATED HEREUNDER OR THEREUNDER.

         (b) To induce Lenders to provide the LIBOR Rate option on the terms
provided herein, if (i) any LIBOR Loans are repaid in whole or in part prior to
the last day of any applicable LIBOR Period (whether that repayment is made
pursuant to any provision of this Agreement or any other Loan Document or is
the result of acceleration, by operation of law or otherwise); (ii) Borrower
shall default in payment when due of the principal amount of or interest on any
LIBOR Loan; (iii) Borrower shall default in making any borrowing of, conversion
into or continuation of LIBOR Loans after Borrower has given notice requesting
the same in accordance herewith; or (iv) Borrower shall fail to make any
prepayment of a LIBOR Loan after Borrower has given a notice thereof in
accordance herewith, then Borrower shall indemnify and hold harmless each
Lender from and against all losses, costs and expenses resulting from or
arising from any of the foregoing. Such indemnification shall include any loss
(including loss of margin) or expense arising from the reemployment of funds
obtained by it or from fees payable to terminate deposits from which such funds
were obtained. For the purpose of calculating amounts payable to a Lender under
this subsection, each Lender shall be deemed to have actually funded its
relevant LIBOR Loan through the purchase of a deposit bearing interest at the
LIBOR Rate in an amount equal to the amount of that LIBOR Loan and having a
maturity comparable to the relevant Interest Period; provided, however, that
each Lender may fund each of its LIBOR Loans in any manner it sees fit, and the
foregoing assumption shall be utilized only for the calculation of amounts
payable under this subsection. This covenant shall survive the termination of
this Agreement and the payment of the Notes and all other amounts payable
hereunder. As promptly as practicable under the circumstances, each Lender
shall provide Borrower with its written calculation of all amounts payable
pursuant to this Section 1.10(b), and such calculation shall be binding on the
parties hereto unless Borrower shall object in writing within ten (10) Business
Days of receipt thereof, specifying the basis for such objection in detail.



                                      -12-
<PAGE>   18


         1.11 ACCESS. Borrower and each of its Subsidiaries shall, during
normal business hours, from time to time upon five (5) Business Days' prior
notice as frequently as Agent reasonably determines to be appropriate: (a)
provide Agent and any of its officers, employees and agents access to its
properties, facilities, advisors and employees (including officers) and (b)
permit Agent, and any of its officers, employees and agents, to inspect, audit
and make extracts from its books and records. If an Event of Default shall have
occurred and be continuing, each of the Borrower and its Subsidiaries shall
provide such access to Agent at all times and without advance notice.

         1.12 TAXES. (a) Any and all payments by Borrower hereunder or under
the Notes shall be made, in accordance with this Section 1.12, free and clear
of and without deduction for any and all present or future Taxes. If Borrower
shall be required by law to deduct any Taxes from or in respect of any sum
payable hereunder or under the Notes, (i) the sum payable shall be increased as
much as shall be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
1.12) Agent, the L/C Issuers or Lenders, as applicable, receive an amount equal
to the sum they would have received had no such deductions been made, (ii)
Borrower shall make such deductions, and (iii) Borrower shall pay the full
amount deducted to the relevant taxing or other authority in accordance with
applicable law. Within thirty (30) days after the date of any payment of Taxes,
Borrower shall furnish to Agent the original or a certified copy of a receipt
evidencing payment thereof.

         (b) Borrower shall indemnify and, within ten (10) days of demand
therefor, pay Agent, each L/C Issuer and each Lender for the full amount of
Taxes (including any Taxes imposed by any jurisdiction on amounts payable under
this Section 1.12) paid by Agent, such L/C Issuer or such Lender, as
appropriate, and any liability (including penalties, interest and expenses)
arising therefrom or with respect thereto, whether or not such Taxes were
correctly or legally asserted.

         (c) Each Lender organized under the laws of a jurisdiction outside the
United States (a "Foreign Lender") as to which payments to be made under this
Agreement or under the Notes are exempt from United States withholding tax
under an applicable statute or tax treaty shall provide to Borrower and Agent a
properly completed and executed IRS Form 4224 or Form 1001 or other applicable
form, certificate or document prescribed by the IRS or the United States
certifying as to such Foreign Lender's entitlement to such exemption (a
"Certificate of Exemption"). Any foreign Person that seeks to become a Lender
under this Agreement shall provide a Certificate of Exemption to Borrower and
Agent prior to becoming a Lender hereunder. No foreign Person may become a
Lender hereunder if such Person is unable to deliver a Certificate of
Exemption.

         (d) Each Lender also agrees to deliver to Borrower and the Agent such
other supplemental forms as may at any time be required as a result of the
passage of time or changes in applicable law or regulation in order to confirm
or maintain in effect its entitlement to exemption from U.S. withholding tax on



                                      -13-
<PAGE>   19


any payments hereunder, provided, that the circumstances of the Lender at the
relevant time and applicable laws permit it to do so. If a Lender determines,
as a result of any change in either (1) applicable law, regulation or treaty,
or in any official application thereof or (2) its circumstances, that it is
unable to submit any form or certificate that it is obligated to submit
pursuant to this Section 1.12(d), or that it is required to withdraw or cancel
any such form or certificate previously submitted, it shall promptly notify the
Lender and the Agent of such fact. If a Lender is organized under the laws of a
jurisdiction outside the United States, and Borrower and the Agent have not
received forms, certificates or other instruments indicating to their
satisfaction that all payments to be made to such Lender hereunder are not
subject to U.S. withholding tax, Borrower shall withhold taxes from such
payments at the applicable statutory rate. Each Lender shall indemnify and hold
Borrower and the Agent harmless from any United States taxes, penalties,
interest and other expenses, costs and losses incurred or payable by them as a
result of either (A) such Lender's failure to submit any form or certificate
that it is required to provide pursuant to this Section 1.12(d) or (B) reliance
by Borrower or the Agent on any such form or certificate which such Lender has
provided to them pursuant to this Section 1.12(d), but in the case of (B), only
to the extent accrued or incurred with respect to payments made prior to such
certificate being withdrawn.

         1.13 CAPITAL ADEQUACY; INCREASED COSTS; ILLEGALITY. (a) If the Agent,
any L/C Issuer or any Lender shall have determined that the adoption after the
date hereof of any law, treaty, governmental (or quasi-governmental) rule,
regulation, guideline or order regarding capital adequacy, reserve requirements
or similar requirements or compliance by the Agent, any L/C Issuer or any
Lender after the date hereof with any request or directive regarding capital
adequacy, reserve requirements or similar requirements (whether or not having
the force of law) from any central bank or other Governmental Authority
increases or would have the effect of increasing the amount of capital,
reserves or other funds required to be maintained by the Agent, such L/C Issuer
or such Lender and thereby reducing the rate of return on such Person's capital
as a consequence of its obligations hereunder, then Borrower shall from time to
time upon demand by such Person (with a copy of such demand to Agent) pay to
Agent, for the account of such Person, additional amounts sufficient to
compensate such Person for such reduction but only to the extent that such
Person reasonably determines such increase in capital to be allocable to the
existence of such Person's Commitment, Loans or interest in Letter of Credit
Obligations hereunder and similar amounts are being charged generally to other
companies with similar commitments from such Person. A certificate as to the
amount of that reduction and showing the basis of the computation thereof
submitted by such Person to Borrower and to Agent shall, absent manifest error,
be final, conclusive and binding for all purposes.

         (b) If, due to either (i) the introduction of or any change in any law
or regulation (or any change in the interpretation thereof) after the date
hereof or (ii) the compliance with any guideline or request from any central
bank or other Governmental Authority (whether or not having the force of law)
after the date hereof, there shall be any increase in the cost to any Lender or
L/C Issuer of agreeing to make or making, funding or maintaining any Advance



                                      -14-
<PAGE>   20


or of agreeing to issue or purchase a participation interest in or in issuing
or purchasing a participation interest in any Letter of Credit or Letter of
Credit Obligation, then Borrower shall from time to time, upon demand by such
Lender or L/C Issuer (with a copy of such demand to Agent), pay to Agent for
the account of such Lender or L/C Issuer additional amounts sufficient to
compensate such Lender or L/C Issuer for such increased cost. A certificate as
to the amount of such increased cost, submitted to Borrower and to Agent by
such Lender or L/C Issuer, shall be conclusive and binding on Borrower for all
purposes, absent manifest error. Each Lender or L/C Issuer agrees that, as
promptly as practicable after it becomes aware of any circumstances referred to
above which would result in any such increased cost, the affected Lender or L/C
Issuer shall, to the extent not inconsistent with such Lender's or L/C Issuer's
internal policies of general application, use reasonable commercial efforts to
minimize costs and expenses incurred by it and payable to it by Borrower
pursuant to this Section 1.13(b).

         (c) Notwithstanding anything to the contrary contained herein, if the
introduction of or any change after the date hereof in any law or regulation
(or any change after the date hereof in the interpretation thereof) shall make
it unlawful, or any central bank or other Governmental Authority shall assert
that it is unlawful, for any Lender to agree to make or to make or to continue
to fund or maintain any LIBOR Loan, then, unless that Lender is able to make or
to continue to fund or to maintain such LIBOR Loan at another branch or office
of that Lender without, in that Lender's sole good faith determination,
adversely affecting it or its Loans or the income obtained therefrom, on notice
thereof and demand therefor by such Lender to Borrower through Agent, (i) the
obligation of such Lender to agree to make or to make or to continue to fund or
maintain LIBOR Loans shall terminate and (ii) Borrower shall forthwith prepay
in full all outstanding LIBOR Loans owing to such Lender, together with
interest accrued thereon, unless Borrower, within five (5) Business Days after
the delivery of such notice and demand, converts all such Loans into Advances
bearing interest based on the Index Rate.

         (d) REPLACEMENT OF LENDER IN RESPECT OF INCREASED COSTS. Within
fifteen (15) days after receipt by Borrower of written notice and demand from
any Lender (an "Affected Lender") for payment of additional amounts or
increased costs as provided in Section 1.12(a), 1.12(b), 1.13(a) or 1.13(b),
Borrower may, at its option, notify Agent and such Affected Lender of its
intention to replace the Affected Lender. So long as no Default or Event of
Default shall have occurred and be continuing, Borrower, with the consent of
Agent, may obtain, at Borrower's expense, a replacement Lender ("Replacement
Lender") for the Affected Lender, which Replacement Lender must be satisfactory
to Agent. If Borrower obtains a Replacement Lender within ninety (90) days
following notice of its intention to do so, the Affected Lender must sell and
assign its Advances, its interest in the Letter of Credit Obligations and
Commitments to such Replacement Lender for an amount equal to the principal
balance of the Revolving Loan held by the Affected Lender and all accrued
interest and Fees with respect thereto through the date of such sale, provided
that Borrower shall have reimbursed such Affected Lender for the additional
amounts or increased costs that it is entitled to receive under this Agreement
through the date of such sale and assignment.



                                      -15-
<PAGE>   21


Notwithstanding the foregoing, Borrower shall not have the right to obtain a
Replacement Lender if the Affected Lender rescinds its demand for increased
costs or additional amounts within fifteen (15) days following its receipt of
Borrower's notice of intention to replace such Affected Lender. Furthermore, if
Borrower gives a notice of intention to replace and does not so replace such
Affected Lender within ninety (90) days thereafter, Borrower's rights under
this Section 1.13(d) shall terminate.

         (e) Each Lender will notify Borrower of any event occurring after the
date of this Agreement which will entitle such Lender to compensation pursuant
to this Section 1.13 as promptly as practicable, and in any event within ninety
(90) days, after such Lender obtains knowledge of the occurrence of such event.
In no event will Borrower be obligated to compensate any Lender pursuant to
this Section 1.13 for any amounts described in clauses (a) or (b) above that
accrued more than ninety (90) days prior to the date that delivery of such
notice was required.

         1.14 SINGLE LOAN. All Advances to Borrower, all Letter of Credit
Obligations and all of the other Obligations of Borrower arising under this
Agreement and the other Loan Documents shall constitute one general obligation
of Borrower secured, until the Termination Date, by all of its Collateral.

2.   CONDITIONS PRECEDENT

         2.1 CONDITIONS TO THE INITIAL LOANS.

cash proceeds from the sale of its common stock in an initial registered
offering of its common stock (the "IPO") and shall have paid the Founder's

         2.2 FURTHER CONDITIONS TO EACH LOAN. Except as otherwise expressly
provided herein, no Lender shall be obligated to fund any Advance, convert or
continue any Advance as a LIBOR Loan or incur any Letter of Credit Obligation,
and no L/C Issuer shall be required to issue any Letter of Credit if, as of the
date thereof:

         (a) Any representation or warranty by any Credit Party contained

or expressly contemplated by this Agreement; or

         (b) Any event or circumstance having a Material Adverse Effect shall

<PAGE>   23


         (c) (i) Any Event of Default shall have occurred and be continuing or
would result after giving effect to any Advance or the incurrence of any Letter

         (d) After giving effect to any Advance or the incurrence of any Letter
of Credit Obligation, the outstanding principal amount of the Revolving Loan
would exceed the lesser of the Revolving Credit Availability and the Maximum
Amount, less, in each case, the then outstanding principal amount of the Swing
Line Loan; or

         (e) After giving effect to any Swing Line Advance, the outstanding
principal amount of the Swing Line Loan would exceed the Swing Line
Availability.

The request and acceptance by Borrower of the proceeds of any Advance, the
incurrence, or request for the incurrence of any Letter of Credit Obligations
or the conversion or continuation of any Loan into, or as, a LIBOR Loan or any
request therefor, as the case may be, shall be deemed to constitute, as of the
date of such request or acceptance, (i) a representation and warranty by
Borrower that the conditions in this Section 2.2 have been satisfied and (ii) a
reaffirmation by Borrower of the granting and continuance of Agent's Liens, on
behalf of itself and Lenders, pursuant to the Collateral Documents.

all of which will have been duly obtained, made or complied with prior to the
Closing Date. On or prior to the Execution Date the Credit Agreement and on or
prior to the Closing Date each of the other Loan Documents, shall have been

all Financial Statements concerning Borrower and its Subsidiaries or any
Founding Radiology Practice which are referenced below have been prepared in
accordance with GAAP consistently applied throughout the periods covered

reasonably be expected to have a Material Adverse Effect, (b) no contract,
lease or other agreement or instrument has been entered into by the Borrower or
any of its Subsidiaries or has become binding upon any such Person's assets and

Adverse Effect, and (c) neither the Borrower nor any of its Subsidiaries is in

other such events, could reasonably be expected to have or result in a Material
Adverse Effect. Since December 31, 1996 no event has occurred, which alone or
together with other events, has had, or could reasonably be expected to have or
result in a Material Adverse Effect.

         3.6 OWNERSHIP OF PROPERTY; LIENS. As of the Closing Date, the real

         3.7 LABOR MATTERS. As of the Closing Date (a) no strikes or other
material labor disputes against any Credit Party or, to the Borrower's
knowledge, any Founding Radiology Practice are pending or, to the Borrower's
knowledge, threatened; (b) hours worked by and payment made to employees of
each Credit Party and, to the Borrower's knowledge, the Founding Radiology
Practices comply with the Fair Labor Standards Act and each other federal,

payments due from any Credit Party or, to



                                      -21-

charges against any Credit Party or, to the Borrower's knowledge, any Founding
Radiology Practice pending or, to the knowledge of the Borrower, threatened to

of, in connection with, or otherwise relating to the employment or termination
of employment by any such Person of any individual.

         3.8 VENTURES, SUBSIDIARIES AND AFFILIATES; OUTSTANDING STOCK AND

Affiliate of any other Person, (c) each of Borrower's Restricted Subsidiaries
and each Permitted Joint Venture Holding Company is a wholly-owned Subsidiary
of Borrower and (d) there are no outstanding rights to purchase, options,
warrants or similar rights or agreements pursuant to which any Credit Party may

of its Subsidiaries. All outstanding Indebtedness of the Borrower and its
Subsidiaries as of the Closing Date is described in Section 6.3 (including
Disclosure Schedule (6.3)).

         3.9 GOVERNMENT REGULATION. No Credit Party is an "investment company"
or an "affiliated person" of, or "promoter" or "principal underwriter" for, an
"investment company," as such terms are defined in the Investment Company Act
of 1940 as amended. No Credit Party is subject to regulation under the Public
Utility Holding Company Act of 1935, the Federal Power Act, or any other
federal or state statute that restricts or limits its ability to incur
Indebtedness or to perform its obligations hereunder. The making of the
Advances by Lenders to Borrower, the incurrence of the Letter of Credit
Obligations on behalf of Borrower, the application of the proceeds thereof and
repayment thereof and the consummation of the Related Transactions will not
violate any provision of any such statute or any rule, regulation or order
issued by the Securities and Exchange Commission.

         3.10 MARGIN REGULATIONS. No Credit Party is engaged, nor will it
engage, principally or as one of its important activities, in the business of
extending credit for the purpose of "purchasing" or



                                      -22-
<PAGE>   28


"carrying" any "margin security" as such terms are defined in Regulation U or G
of the Federal Reserve Board as now and from time to time hereafter in effect
(such securities being referred to herein as "Margin Stock"). No Credit Party
owns any Margin Stock (except for investments permitted pursuant to Section
6.2(a)(v)), and none of the proceeds of the Loans or other extensions of credit
under this Agreement will be used, directly or indirectly, for the purpose of
purchasing or carrying any Margin Stock, for the purpose of reducing or
retiring any Indebtedness which was originally incurred to purchase or carry
any Margin Stock or for any other purpose which might cause any of the Loans or
other extensions of credit under this Agreement to be considered a "purpose
credit" within the meaning of Regulation G, T, U or X of the Federal Reserve
Board. No Credit Party will take or permit to be taken any action which might
cause any Loan Document to violate any regulation of the Federal Reserve Board.

         3.11 TAXES. All tax returns, reports and statements, including
information returns, required by any Governmental Authority to be filed by any
Credit Party have been filed with the appropriate Governmental Authority and
all Charges have been paid prior to the date on which any fine, penalty,
interest or late charge may be added thereto for nonpayment thereof (or any
such fine, penalty, interest, late charge or loss has been paid), excluding
Charges or other amounts being contested in accordance with Section 5.2(b),
except for such filings or payments, the non-payment of which, individually or
in the aggregate, have not had and could not reasonably be expected to have or
result in a Material Adverse Effect. Proper and accurate amounts have been
withheld by each Credit Party from its respective employees for all periods in
full and complete compliance with all applicable federal, state, local and
foreign law and such withholdings have been timely paid to the respective
Governmental Authorities except for such withholdings and payments, the failure
to make which, individually or in the aggregate, have not had and could not
reasonably be expected to have or result in a Material Adverse Effect.
Disclosure Schedule (3.11) sets forth as of the Closing Date those taxable
years for which any Credit Party's tax returns are currently being audited by
the IRS or any other applicable Governmental Authority and any assessments or
threatened assessments in connection with such audit, or otherwise currently
outstanding. Except as described on Disclosure Schedule (3.11), no Credit Party
has executed or filed with the IRS or any other Governmental Authority any
agreement or other document extending, or having the effect of extending, the
period for assessment or collection of any Charges. No Credit Party or, to the
Borrower's knowledge, their respective predecessors are liable for any Charges:
(a) under any agreement (including any tax sharing agreements) or (b) to
Borrower's knowledge, as a transferee.

         3.12 ERISA. (a) As of the Closing Date, Disclosure Schedule (3.12)
lists and separately identifies all Title IV Plans, Multiemployer Plans, ESOPs
and Retiree Welfare Plans. Copies of all such listed Plans, together with a
copy of the latest form 5500 for each such Plan, have been delivered to Agent.
Each Qualified Plan has been determined by the IRS to qualify under Section 401
of the IRC, and the trusts created thereunder have been determined to be exempt
from tax under the provisions of Section 501 of the IRC, and nothing has
occurred which would cause the loss of such qualification or tax-exempt status.
Each Plan is in material compliance with the applicable provisions of ERISA and
the IRC,



                                      -23-
<PAGE>   29


including the filing of reports required under the IRC or ERISA. Neither the
Borrower nor any ERISA Affiliate has failed to make any contribution or pay any
amount due as required by either Section 412 of the IRC or Section 302 of ERISA
or the terms of any such Plan. Neither the Borrower nor any ERISA Affiliate has
engaged in a prohibited transaction, as defined in Section 4975 of the IRC, in
connection with any Plan, which would subject any of the Borrower's or its
Subsidiaries to a material tax on prohibited transactions imposed by Section
4975 of the IRC.

         (b) Except as set forth in Disclosure Schedule (3.12): (i) no Title IV
Plan has any Unfunded Pension Liability; (ii) no ERISA Event or event described
in Section 4062(e) of ERISA with respect to any Title IV Plan has occurred or
is reasonably expected to occur, which individually or in the aggregate, has
had or could reasonably be expected to have or result in a Material Adverse
Effect; (iii) there are no pending, or to the knowledge of Borrower, threatened
claims (other than claims for benefits in the normal course), sanctions,
actions or lawsuits, asserted or instituted against any Plan or any Person as
fiduciary or sponsor of any Plan, which have a reasonable risk of being
determined adversely and which, if so determined, individually or in the
aggregate, could have a Material Adverse Effect; (iv) neither the Borrower nor
any ERISA Affiliate has incurred or reasonably expects to incur any liability
as a result of a complete or partial withdrawal from a Multiemployer Plan; (v)
within the last five years no Title IV Plan with Unfunded Pension Liabilities
has been transferred outside of the "controlled group" (within the meaning of
Section 4001(a)(14) of ERISA) of the Borrower or any ERISA Affiliate; and (vi)
no liability under any Title IV Plan has been satisfied with the purchase of a
contract from an insurance company that is not rated AAA by the Standard &
Poor's Corporation or the equivalent by another nationally recognized rating
agency.

         3.13 NO LITIGATION. No action, claim, lawsuit, demand, investigation
or proceeding is now pending or, to the knowledge of Borrower, threatened
against any of the Borrower, any of its Subsidiaries or, to the knowledge of
the Borrower, any Managed Practice, before any Governmental Authority or before
any arbitrator or panel of arbitrators (collectively, "Litigation"), (a) which
challenges any Credit Party's or any Managed Practice's right or power to enter
into or perform any of its obligations under the Related Transaction Documents
to which it is a party, or the validity or enforceability of any Related
Transaction Document or any action taken thereunder, or (b) which has a
reasonable risk of being determined adversely to any of the Borrower, any of
its Subsidiaries or, to the knowledge of the Borrower, any Managed Practice and
which, if so determined, could have a Material Adverse Effect. Except as set
forth on Disclosure Schedule (3.13), as of the Closing Date there is no
Litigation pending or threatened which seeks damages in excess of $500,000 in
excess of acknowledged insurance coverage from a recognized carrier or
injunctive relief or alleges criminal misconduct of any of the Borrower, any of
its Subsidiaries or, to the knowledge of the Borrower, any Founding Radiology
Practice. There is no pending investigation of any of the Borrower, any of its
Subsidiaries, any Permitted Joint Venture or, to the knowledge of the Borrower,
any Managed Practice by HCFA or any other Governmental Authority, which
investigation is not otherwise conducted in the ordinary course of business and
no criminal, civil or administrative action, audit, or investigation by a
fiscal intermediary or by or



                                      -24-
<PAGE>   30


on behalf of any Governmental Authority exists or, to the best knowledge of the
Borrower, is threatened with respect to any of the Borrower, any of its
Subsidiaries or, to the knowledge of the Borrower, any Managed Practice, which
has had or could reasonably be expected to have or result in a Material Adverse
Effect (including by way of an adverse effect on such Person's right to receive
Medicare, Medicaid, CHAMPUS or CHAMPVA reimbursement to which such Person would
otherwise be entitled, or right to participate in the Medicare, Medicaid,
CHAMPUS or CHAMPVA programs or on the ability of such Person to engage in the
practice of medicine or to fulfill its obligations as contemplated under the
Loan Documents or any Service Agreement), and, to the best knowledge of the
Borrower, no such Person is subject to any pending but unassessed Medicare,
Medicaid, CHAMPUS or CHAMPVA claim payment adjustments, except to the extent
that such Person is contesting such assessment in good faith by appropriate
proceedings diligently pursued and has established and will maintain adequate
reserves for such adjustments in accordance with GAAP, except to the extent
that any such payment adjustment, individually or in the aggregate, has not had
and could not reasonably be expected to have or result in a Material Adverse
Effect.

         3.14 BROKERS. No broker or finder acting on behalf of any Credit Party
brought about the obtaining, making or closing of the Loans or the Related
Transactions, and no Credit Party has any obligation to any Person in respect
of any finder's or brokerage fees in connection therewith.

         3.15 INTELLECTUAL PROPERTY. As of the Closing Date, each Credit Party
owns or has rights to use all Intellectual Property necessary to continue to
conduct its business as now or heretofore conducted by it or proposed to be
conducted by it, and each Patent, Trademark, Copyright and License is listed,
together with application or registration numbers, as applicable, in Disclosure
Schedule (3.15) hereto. Each Credit Party conducts its business and affairs
without infringement of or interference with any Intellectual Property of any
other Person in any manner that, individually or in the aggregate, has had or
could reasonably be expected to have or result in a Material Adverse Effect.

         3.16 FULL DISCLOSURE. No information contained in this Agreement, any
of the other Loan Documents, any Projections, the Disclosure Documents or
Financial Statements or other reports from time to time delivered hereunder or
any written statement furnished by Borrower or on its behalf or on behalf of
any of its Subsidiaries or Permitted Joint Venture or, to the knowledge of the
Borrower, any Managed Practice to Agent or any Lender pursuant to the terms of
this Agreement contains or will contain any untrue statement of a material fact
or omits or will omit to state a material fact necessary to make the statements

which they were made. The Liens granted to Agent, on behalf of itself and
Lenders, pursuant to the Collateral Documents will at all times be fully

Agreement complies with, and the Acquisition has been consummated in accordance
with, all applicable laws. Each Acquisition Agreement and each Service
Agreement is in full force and effect as of the Closing Date and has not been
terminated, rescinded or withdrawn. All requisite approvals by Governmental
Authorities having jurisdiction over any Credit Party or, to the knowledge of
Borrower, any Managed Practice or any other Persons referenced therein, with
respect to the transactions contemplated by the Acquisition Agreements and the
Service Agreements, have been obtained, and no such approvals impose any
conditions to the consummation of the transactions contemplated by the
Acquisition Agreements or to the conduct by any Credit Party or, to the
knowledge of Borrower, any Managed Practice of its business thereafter as
contemplated by the Service Agreements. To Borrower's knowledge, none of the
Founding Radiology Practices' representations or warranties in the Acquisition
Agreements contains any untrue statement of a material fact or omits any fact
necessary to make the statements therein not misleading. Each of the
representations and warranties given by each of the Borrower, its Subsidiaries
or (to Borrower's knowledge) any Founding Radiology Practice in the Acquisition
Agreements is true and correct in all material respects. Notwithstanding
anything contained in the Acquisition Agreements to the contrary, such
representations and warranties of the Credit Parties are incorporated into this
Agreement by this Section 3.24 and shall, solely for purposes of this Agreement
and the benefit of Agent and Lenders, survive the consummation of such
Acquisitions.

Payors, to the Borrower's knowledge, (a) none of such audits provides for
adjustments in reimbursable costs or asserts claims for reimbursement or
repayment by such Person of costs and/or payments theretofore made by such

in the aggregate, could reasonably be expected to have or result in a Material
Adverse Effect and (b) no Managed Practice has had requests or assertions of

made by any other Third Party Payor that, if adversely determined, individually

an Existing Permitted Joint Venture or Acquired Permitted Joint Venture to the
extent that the organizational documents of such Existing Permitted Joint
Venture or Acquired Permitted Joint Venture in effect at the time of the
acquisition thereof prohibit the pledge of its Stock, and (iv) the investment
in which complies with Section 6.2), or (y) merge with, consolidate with,

Stock of any radiology practice or practice group or imaging center or other
business providing similar services, including services ancillary to such

substantially all of the assets of any practice or practice group shall not be
deemed to require the acquisition of assets customarily retained by a Managed
Practice following such an acquisition) or of a Person (a "PPM") that owns,
operates or manages such groups or businesses (the "Acquisition Target") that
meets each of the following conditions (each, a "Permitted Acquisition"):

                                      -32-
<PAGE>   38


          (iii) the Agent shall have received on or within 10 days following
     the closing date of any such Permitted Acquisition: (A)(1) with respect to
     a Practice Acquisition, copies of each of the Service Agreements,
     acquisition or merger agreements, professional employment and
     non-competition agreements and all other agreements executed in connection
     with such acquisition, the terms and conditions of which agreements shall
     be substantially similar to the terms and conditions of the Service
     Agreements, Acquisition Agreements and other Related Transaction Documents
     executed in connection with the Related Transactions (which terms and
     conditions shall include, without limitation, the duration of the Service
     and Employment Agreements, the termination and practice repurchase
     provisions, practice governance provisions and provisions regarding the
     assignability as security to the Agent and which terms and conditions the
     Borrower shall use its reasonable best efforts to cause to include
     limitations on Managed Practice liabilities), and (2) with respect to
     other acquisitions, copies of the acquisition or merger agreements and all
     other agreements executed in connection with such acquisition, and (B)
     such opinions, certificates, lien search results and other documents as

     to be paid (whether by cash, stock, assumption of debt or otherwise) by
     the Borrower and its Restricted Subsidiaries equals or exceeds $3,500,000,
     Borrower shall have delivered to Agent, in form and substance satisfactory
     to Agent, a certificate of the chief financial officer of Borrower in the
     form of Schedule 6.1(b) to the effect that: (A) at the time of such
     Permitted Acquisition and after giving effect thereto, no Default or Event
     of Default will have occurred and be continuing; and (B) on a pro forma
     basis Borrower would have been in compliance with the financial covenants
     set forth in Annex E as of the most recent test period for which such
     covenants were tested, which covenants shall be calculated (in addition to
     the assumptions specified in Annex E) as if: (x) such acquisition and all
     other acquisitions closed or to be closed following such test period and
     prior to the proposed closing date of the proposed Permitted Acquisition
     had occurred at the beginning of such test period and Borrower had
     received income attributable to such Acquisition Target and such other
     acquired entities based on the actual performance of such Acquisition
     Target and such other acquired entities over such period (adjusted to
     reflect the pro forma effect of Borrower's physician compensation model as
     appropriate) and had incurred the Indebtedness and expenses incurred to
     purchase such Acquisition Target and such other acquired entity at the
     beginning of such period and repaid, retired, disposed of or refinanced
     any Indebtedness repaid, retired, disposed of or refinanced or to be
     repaid, retired, disposed of or refinanced in such acquisition at the
     beginning of such period, and (y) any disposition of Stock or of all or
     substantially all of the assets of any Subsidiary or Permitted Joint
     Venture by Borrower or any of its Subsidiaries and any termination of a
     Service Agreement (which Service Agreement is not contemporaneously
     replaced by a Service Agreement with the same Managed Practice that
     provides substantially the same EBITDA to Borrower and its



                                      -33-

     Subsidiaries as the terminated Service Agreement) that have occurred or
     are to occur following such test period and prior to the proposed closing
     date of the proposed Permitted Acquisition had occurred at the beginning
     of such test period and the Borrower had not received any EBITDA
     attributable to such entity disposed of or to such terminated Service
     Agreement over such period and had incurred any Indebtedness or expense
     incurred in connection with such disposition or termination at the
     beginning of such period and had repaid, retired, disposed of or
     refinanced any Indebtedness that was or is to be repaid, retired or
     disposed of or refinanced in connection with such disposition or
     termination (to the extent that the Borrower and its Subsidiaries have
     been, or are to be, released from all liability with respect thereto) at
     the beginning of such period; and

          (v) on or prior to the date of such Permitted Acquisition, Agent
     shall have received, in form and substance satisfactory to Agent, such
     documents and instruments as it shall require to evidence the joinder of
     any new Subsidiary, other than a Permitted Joint Venture, to the
     Subsidiary Guaranty and Subsidiary Pledge and Security Agreement and the
     perfection of all liens created thereunder (subject, in the case of an
     Acquired Permitted Joint Venture, to the provisions of Subsection
     6.1(b)(iv)).

         (b) (i) The Borrower shall not and shall not permit any of its
Subsidiaries to, create, own or acquire any Stock in any Person other than: (A)
Stock in itself to the extent permitted elsewhere in this Agreement, (B) Stock
in a Subsidiary created, owned or acquired in accordance with Section 6.1(a),
(C) Stock that constitutes a permitted investment by virtue of clauses (A)
through (H) of subsection (v) of Section 6.2(a), or (D) Stock in a Permitted
Joint Venture in compliance with this Section 6.1(b).

         (ii) Any Existing Permitted Joint Venture is listed on Disclosure
Schedule 6.1(b), along with a description of its ownership and organizational
structure and Indebtedness, and each is designated as either a Levered
Permitted Joint Venture or an Unlevered Permitted Joint Venture..

         (iii) (A) Neither the Borrower nor any of its Subsidiaries shall
create or acquire any Stock in any Permitted Joint Venture after the Closing
Date unless it shall notify the Agent thereof within five (5) days following
such creation or acquisition. Such notice shall include a description of the
ownership, organizational structure and Indebtedness of such Permitted Joint
Venture and shall designate such Permitted Joint Venture as either a Levered
Permitted Joint Venture or an Unlevered Permitted Joint Venture. If such
Permitted Joint Venture is an Acquired Permitted Joint Venture, such notice
shall also describe the circumstances of such acquisition except to the extent
that such description is already being provided pursuant to Section 6.1(a). No
Credit Party may hold Stock in any Permitted Joint Venture that is not a
corporation except through a Permitted Joint Venture Holding Company.

         (B) If the aggregate consideration paid or invested upon the creation
or acquisition of Stock in any Permitted Joint Venture (other than an Acquired
Permitted Joint



                                      -34-

Venture) shall exceed $3,500,000, the Borrower shall also comply with the
provisions of paragraphs (i) and (iv) of clause (3) of the second sentence of
Section 6.1(a) with respect to such creation or acquisition.

         (iv) At the Closing Date, in the case of Existing Permitted Joint
Ventures, and otherwise at the time of the acquisition or creation of any Stock
therein, the Borrower shall deliver and/or shall cause the applicable
Subsidiary to deliver to the Agent in pledge as security for the Obligations,
all Stock that the Borrower or any of its Subsidiaries holds in such Permitted
Joint Venture, PROVIDED that the pledge of the Stock in the Permitted Joint
Venture shall not be required if such Permitted Joint Venture is an Existing
Permitted Joint Venture or an Acquired Permitted Joint Venture to the extent
that, at the time of the acquisition thereof, the organizational documents
thereof prohibit such pledge.

         (v) If at the time any Permitted Joint Venture is acquired or created
it shall have outstanding Indebtedness or liabilities in excess of $5,000,000,
then the Borrower shall submit to the Agent evidence satisfactory to the Agent
in its good faith discretion that none of the Indebtedness or liabilities of
such Permitted Joint Venture are, or could reasonably be expected to become,
Indebtedness or liabilities of the Borrower or any other Subsidiary other than
the Permitted Joint Venture Holding Company that owns the Stock in such
Permitted Joint Venture, except that this paragraph (v) shall not apply to the
extent that any such Indebtedness constitutes Permitted Recourse Debt.

         (vi) No Restricted Subsidiary may become an Unrestricted Subsidiary,
no Unrestricted Subsidiary may become a Restricted Subsidiary, no Levered
Permitted Joint Venture may become an Unlevered Permitted Joint Venture and no
Unlevered Permitted Joint Venture may become a Levered Permitted Joint Venture;

and be continuing or would result therefrom, Borrower may upon prior written
notice to the Agent redesignate an Levered Permitted Joint Venture that
otherwise meets the requirements of an Unlevered Permitted Joint Venture to be
an Unlevered Permitted Joint Venture. Upon any such redesignation, the Borrower
may reclassify amounts invested in such Permitted Joint Venture during the
Fiscal Year in which such redesignation occurs and prior to such redesignation
from investments in Levered Permitted Joint Ventures to investments in
Unlevered Permitted Joint Ventures for the purpose of Section 6.2(a)(iii)(A).

         6.2 INVESTMENTS; LOANS AND ADVANCES. (a) Except as otherwise expressly
permitted by this Section 6.2, no Credit Party shall make or permit to exist

money to, any Person, through the direct or indirect lending of money, holding
of securities or otherwise, except that:

            (i) any Credit Party may make loans or advances to employees for
     reimbursable expenses in the ordinary course of business and as permitted
     in Section 6.4(b);

           (ii) the Borrower may make and maintain equity investments in its
     Restricted Subsidiaries and may make and maintain loans or advances to its
     Restricted Subsidiaries and the Restricted Subsidiaries may make and
     maintain loans and advances to the Borrower, provided that such loans or
     advances are evidenced by notes and all such equity investments and loans
     or advances are pledged to the Agent as security for the Obligations;

           (iii) any Credit Party may make and maintain equity investments in,
     and make loans and advances to, Permitted Joint Ventures and Permitted
     Joint Venture Holding Companies and subject to the following limitations:

               (A) the aggregate amount that may be invested in Permitted Joint
          Ventures by the Borrower and its Subsidiaries, taken as a whole,
          shall not exceed $20,000,000 in any Fiscal Year, and, of that amount,
          the aggregate amount that may be invested in Levered Permitted Joint
          Ventures shall not exceed $10,000,000 in any Fiscal Year, provided,
          that for the purposes of this Section 6.2(a)(iii)(A), there shall be
          excluded from the amount invested in Permitted Joint Ventures the
          amount invested in any (x) Existing Permitted Joint Venture on the
          Closing Date and (y) Acquired Permitted Joint Venture in connection
          with the initial acquisition thereof except to the extent that the
          EBITDA of such Acquired Permitted Joint Venture exceeds 25% of the
          total EBITDA of the Acquisition Target the purchase of which resulted
          in the acquisition of such Acquired Permitted Joint Venture (the
          "Excess EBITDA;" in such case the amount deemed invested in such
          Acquired Permitted Joint Venture for the purpose of this Section
          6.2(a)(iii)(A) shall equal the aggregate consideration paid for such
          Acquisition Target, multiplied by a fraction, the numerator of which
          is the amount of such Excess EBITDA, and the denominator of which is
          the total EBITDA of such Acquisition Target),

               (B) if such investment constitutes an equity investment, such
          investment shall be pledged to the Agent as security for the
          Obligations to the extent provided in Section 6.1(b)(iv),

               (C) all investments constituting loans or advances shall be
          evidenced by a note and pledged to the Agent as additional security
          for the Obligations,

               (D) if the aggregate amount invested in any one Permitted Joint

writing its inability to, or shall be generally unable to, pay its debts as
such debts become due.

         (j) A final judgment or judgments for the payment of money in excess
of $2,000,000 in the aggregate at any time outstanding shall be rendered
against any Credit Party and the same shall not, within thirty (30) days after
the entry thereof, have been discharged or execution thereof stayed or bonded
pending appeal, or shall not have been discharged prior to the expiration of
any such stay.

         (k) Any material provision of any Loan Document shall for any reason
cease to be valid, binding and enforceable in accordance with its terms (or any
Credit Party shall challenge the enforceability of any Loan Document or shall
assert in writing, or engage in any action or inaction based on any such
assertion, that any provision of any of the Loan Documents has ceased to be or
otherwise is not valid, binding and enforceable in accordance with its terms),
or any security interest created under any Loan Document shall cease to be a
valid and perfected first priority security interest or Lien (except as
otherwise permitted herein or therein) in any of the Collateral purported to be
covered thereby other than as a result of the failure of the Agent to timely
file any continuation statement or maintain possession of any collateral under
its control.

         (l) Any Change of Control shall occur.

         (m) The termination of, or the receipt by any Credit Party of notice
of the termination of, or the occurrence of any event or condition which would,
with the passage of time or the giving of notice or both, constitute an event
of default under or permit the termination of, any one or more Service
Agreements with respect to any Material Managed Practice.

         (n) Any Credit Party or any Managed Practice shall be prohibited or
otherwise restrained from conducting the business theretofor conducted by it in
any manner that has or could reasonably be expected to have or result in a
Material Adverse Effect by virtue of any determination, ruling, decision,
decree or order of any court or Governmental Authority of competent
jurisdiction.

         (o) The introduction of, or any change in, any law or regulation
governing or affecting a physician practice management company or any practice
or practice group managed thereby, including without limitation any Healthcare
Laws, which could reasonably be expected to have a Material Adverse Effect.



                                      -46-
<PAGE>   52


         (p) A default or breach shall occur under any other agreement,
document or instrument to which any Material Managed Practice is a party which
is not cured within any applicable grace period, and such default or breach,
individually or when aggregated with all such defaults or breaches, could
reasonably be expected to have or result in a Material Adverse Effect.

         8.2 REMEDIES. (a) If any Event of Default shall have occurred and be
continuing, or if a Default shall have occurred and be continuing and Agent or
Requisite Lenders shall have determined not to make any Advances or incur any
Letter of Credit Obligations so long as that specific Default is continuing,
Agent may (and at the written request of the Requisite Lenders shall), without
notice, suspend this facility with respect to further Advances and/or the
incurrence of further Letter of Credit Obligations whereupon any further
Advances and Letter of Credit Obligations shall be made or extended in Agent's
sole discretion (or in the sole discretion of the Requisite Lenders, if such
suspension occurred at their direction) so long as such Default or Event of
Default is continuing. If any Payment Default shall have occurred and be
continuing, Agent may (and at the written request of Requisite Lenders shall),
without notice except as otherwise expressly provided herein, increase the rate
of interest applicable to the Loans and the Letter of Credit Fees to the
Default Rate.

         (b) If any Event of Default shall have occurred and be continuing,
Agent may (and at the written request of the Requisite Lenders shall), without
notice, (i) terminate this facility with respect to further Advances or the
incurrence of further Letter of Credit Obligations; (ii) declare all or any
portion of the Obligations, including all or any portion of any Loan to be
forthwith due and payable, and require that the Letter of Credit Obligations be
cash collateralized as provided in Annex B, all without presentment, demand,
protest or further notice of any kind, all of which are expressly waived by
Borrower and each other Credit Party; and (iii) exercise any rights and
remedies provided to Agent under the Loan Documents and/or at law or equity,
including all remedies provided under the Code; provided, however, that upon
the occurrence of an Event of Default specified in Sections 8.1(h) or (i), all
of the Obligations, including the Revolving Loan, shall become immediately due
and payable without declaration, notice or demand by any Person.

         8.3 WAIVERS BY CREDIT PARTIES. Except as otherwise provided for in
this Agreement or by applicable law, each of Borrower and its Subsidiaries
waives: (a) presentment, demand and protest and notice of presentment,
dishonor, notice of intent to accelerate, notice of acceleration, protest,
default, nonpayment, maturity, release, compromise, settlement, extension or
renewal of any or all commercial paper, accounts, contract rights, documents,
instruments, chattel paper and guaranties at any time held by Agent on which
any Credit Party may in any way be liable, and hereby ratifies and confirms
whatever Agent may do in this regard, (b) all rights to notice and a hearing
prior to Agent's taking possession or control of, or to Agent's replevy,



                                      -47-
<PAGE>   53


attachment or levy upon, the Collateral or any bond or security which might be
required by any court prior to allowing Agent to exercise any of its remedies,
and (c) the benefit of all valuation, appraisal, marshaling and exemption laws.

9.   ASSIGNMENT AND PARTICIPATIONS; APPOINTMENT OF AGENT

         9.1 ASSIGNMENT AND PARTICIPATIONS. Subject to the provisions of
paragraphs (a) and (b) below, the Borrower hereby consents to any Lender's
assignment of, and/or sale of participations in, at any time or times, the Loan
Documents, Loans, Letter of Credit Obligations and any Commitment or of any
portion thereof or interest therein, including any Lender's rights, title,
interests, remedies, powers or duties thereunder, whether evidenced by a
writing or not.

         (a) Any assignment by a Lender shall (i) require the consent of Agent
and, absent the occurrence and continuance of an Event of Default, Borrower
(which consent, in each case, shall not be unreasonably withheld or delayed)
and the execution of an assignment agreement (an "Assignment Agreement"
substantially in the form attached hereto as Exhibit 9.1(a) and otherwise in
form and substance satisfactory to, and acknowledged by, Agent); (ii) be
conditioned on such assignee Lender representing to the assigning Lender and
Agent that it is purchasing the applicable Loans to be assigned to it for its
own account, for investment purposes and not with a view to the distribution
thereof; (iii) if a partial assignment, be in an amount at least equal to
$5,000,000 and, after giving effect to any such partial assignment, the
assigning Lender shall have retained Commitments in an amount at least equal to
$5,000,000; (iv) include a payment to Agent of an assignment fee of $3,500; and
(v) absent the occurrence and continuance of an Event of Default, be only to an
Eligible Assignee. In the case of an assignment by a Lender under this Section
9.1, the assignee shall have, to the extent of such assignment, the same
rights, benefits and obligations as it would if it were a Lender hereunder. The
assigning Lender shall be relieved of its obligations hereunder with respect to
its Commitments or assigned portion thereof from and after the date of such
assignment. Borrower hereby acknowledges and agrees that any assignment will
give rise to a direct obligation of Borrower to the assignee and that the
assignee shall be considered to be a "Lender". In all instances, each Lender's
liability to make Loans hereunder shall be several and not joint and shall be
limited to such Lender's Pro Rata Share of the applicable Commitment. In the
event Agent or any Lender assigns or otherwise transfers all or any part of a
Note, Agent or any such Lender shall so notify Borrower and Borrower shall,
upon the request of Agent or such Lender, execute new Notes in exchange for the
Notes being assigned. Notwithstanding the foregoing provisions of this Section
9.1(a), any Lender may at any time pledge or assign all or any portion of such
Lender's rights under this Agreement and the other Loan Documents to a Federal
Reserve Bank; provided, however, that no such pledge or assignment shall
release such Lender from such Lender's obligations hereunder or under any other
Loan Document.

         (b) Any participation by a Lender of all or any part of its
Commitments shall be in an amount at least equal to $5,000,000, and with the
understanding that all amounts payable by Borrower hereunder shall be
determined as if that Lender had not sold such participation, and that the
holder of any such participation shall not be entitled



                                      -48-
<PAGE>   54


to require such Lender to take or omit to take any action hereunder except
actions directly affecting (i) any reduction in the principal amount of, or
interest rate or Fees payable with respect to, any Loan in which such holder
participates, (ii) any extension of the scheduled amortization of the principal
amount of any Loan in which such holder participates or the final maturity date
thereof, and (iii) any release of all or substantially all of the Collateral
(other than in accordance with the terms of this Agreement, the Collateral
Documents or the other Loan Documents). Solely for purposes of Sections 1.10,
1.12, 1.13 and 9.8, Borrower acknowledges and agrees that a participation shall
give rise to a direct obligation of Borrower to the participant and the
participant shall be considered to be a "Lender". Except as set forth in the
preceding sentence neither Borrower nor any other Credit Party shall have any
obligation or duty to any participant. Neither Agent nor any Lender (other than
the Lender selling a participation) shall have any duty to any participant and
may continue to deal solely with the Lender selling a participation as if no
such sale had occurred.

         (c) Except as expressly provided in this Section 9.1, no Lender shall,
as between Borrower and that Lender, or Agent and that Lender, be relieved of
any of its obligations hereunder as a result of any sale, assignment, transfer
or negotiation of, or granting of participation in, all or any part of the
Loans, the Notes or other Obligations owed to such Lender.

         (d) Borrower and each of its Subsidiaries shall assist any Lender
permitted to sell assignments or participations under this Section 9.1 as
reasonably required to enable the assigning or selling Lender to effect any
such assignment or participation, including the execution and delivery of any
and all agreements, notes and other documents and instruments as shall be
requested and the delivery of informational materials for, and the
participation of management in meetings with, potential assignees or
participants. Borrower and each of its Subsidiaries shall certify the
correctness, completeness and accuracy of all descriptions of such Credit Party
and their affairs contained in any selling materials provided by it and all
other information provided by it and included in such materials, except that
any Projections delivered by Borrower shall only be certified by Borrower as
having been prepared by Borrower in compliance with the representations
contained in Section 3.4(c).

         (e) A Lender may furnish any information concerning Borrower in the
possession of such Lender from time to time to assignees and participants
(including prospective assignees and participants). Each Lender shall obtain
from assignees or participants confidentiality covenants substantially
equivalent to those contained in Section 11.8.

         (f) So long as no Event of Default shall have occurred and be
continuing, no Lender shall assign or sell participations in any portion of its
Loans or Commitments to a potential Lender or participant, if, as of the date
of the proposed assignment or sale, the assignee Lender or participant would be
subject to capital adequacy or similar requirements under Section 1.13(a),
increased costs under Section 13(b), an inability to fund LIBOR Loans under
Section 1.13(c), or withholding taxes in accordance with Section 1.13(d).

         9.2 APPOINTMENT OF AGENT. GE Capital is hereby appointed to act on
behalf of all Lenders as Agent under this Agreement and the other Loan
Documents. The provisions of this Section 9.2 are solely for the benefit of
Agent and Lenders and no Credit Party nor any other Person shall have any
rights as a third party beneficiary of any of the provisions hereof. In
performing its functions and duties under this Agreement and the other Loan
Documents, Agent shall act solely as an agent of Lenders and does not assume
and shall not be deemed to have assumed any obligation toward or relationship
of agency or trust with or for any Credit Party or any other Person. Agent
shall have no duties or responsibilities except for those expressly set forth
in this Agreement and the other Loan Documents. The duties of Agent shall be
mechanical and administrative in nature and Agent shall not have, or be deemed
to have, by reason of this Agreement, any other Loan Document or otherwise a
fiduciary relationship in respect of any Lender. Neither Agent nor any of its
Affiliates nor any of their respective officers, directors, employees, agents
or representatives shall be liable to any Lender for any action taken or
omitted to be taken by it hereunder or under any other Loan Document, or in
connection herewith or therewith, except for damages caused by its or their own
gross negligence or willful misconduct.

         If Agent shall request instructions from Requisite Lenders or all
affected Lenders with respect to any act or action (including failure to act)
in connection with this Agreement or any other Loan Document, then Agent shall
be entitled to refrain from such act or taking such action unless and until
Agent shall have received instructions from Requisite Lenders or all affected
Lenders, as the case may be, and Agent shall not incur liability to any Person
by reason of so refraining. Agent shall be fully justified in failing or
refusing to take any action hereunder or under any other Loan Document (a) if
such action would, in the opinion of Agent, be contrary to law or the terms of
this Agreement or any other Loan Document, (b) if such action would, in the
opinion of Agent, expose Agent to Environmental Liabilities or (c) if Agent
shall not first be indemnified to its satisfaction against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. Without limiting the foregoing, no Lender
shall have any right of action whatsoever against Agent as a result of Agent
acting or refraining from acting hereunder or under any other Loan Document in
accordance with the instructions of Requisite Lenders or all affected Lenders,
as applicable.

         9.3 AGENT'S RELIANCE, ETC. Neither Agent nor any of its Affiliates nor
any of their respective directors, officers, agents or employees shall be
liable for any action taken or omitted to be taken by it or them under or in
connection with this Agreement or the other Loan Documents, except for damages
caused by its or their own gross negligence or willful misconduct. Without
limitation of the generality of the foregoing, Agent: (a) may treat the payee
of any Note as the holder thereof until Agent receives written notice of the
assignment or transfer thereof signed by such payee and in form satisfactory to
Agent; (b) may consult with legal counsel, independent public accountants and
other experts selected by it and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts; (c) makes no warranty or representation to any
Lender and shall not be responsible to any Lender for any statements,
warranties or representations made in or in connection with this Agreement or



                                      -50-
<PAGE>   56


the other Loan Documents; (d) shall not have any duty to ascertain or to
inquire as to the performance or observance of any of the terms, covenants or
conditions of this Agreement or the other Loan Documents on the part of any
Credit Party or to inspect the Collateral (including the books and records) of
any Credit Party; (e) shall not be responsible to any Lender for the due
execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or the other Loan Documents or any other instrument or
document furnished pursuant hereto or thereto; and (f) shall incur no liability
under or in respect of this Agreement or the other Loan Documents by acting
upon any notice, consent, certificate or other instrument or writing (which may
be by telecopy, telegram, cable or telex) believed by it to be genuine and
signed or sent by the proper party or parties.

         9.4 GE CAPITAL AND AFFILIATES. With respect to its Commitments
hereunder, GE Capital shall have the same rights and powers under this
Agreement and the other Loan Documents as any other Lender and may exercise the
same as though it were not Agent; and the term "Lender" or "Lenders" shall,
unless otherwise expressly indicated, include GE Capital in its individual
capacity. GE Capital and its Affiliates may lend money to, invest in, and
generally engage in any kind of business with, any Credit Party, any of their
Affiliates and any Person who may do business with or own securities of any
Credit Party or any such Affiliate, all as if GE Capital were not Agent and
without any duty to account therefor to Lenders. GE Capital and its Affiliates
may accept fees and other consideration from any Credit Party for services in
connection with this Agreement or otherwise without having to account for the
same to Lenders. Each Lender acknowledges the potential conflict of interest
between GE Capital as a Lender holding disproportionate interests in the Loans
and GE Capital as Agent.

         9.5 LENDER CREDIT DECISION. Each Lender acknowledges that it has,
independently and without reliance upon Agent or any other Lender and based on
the Financial Statements referred to in Section 3.4(a) and such other documents
and information as it has deemed appropriate, made its own credit and financial
analysis of the Credit Parties and its own decision to enter into this
Agreement. Each Lender also acknowledges that it will, independently and
without reliance upon Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement. Each
Lender acknowledges the potential conflict of interest of each other Lender as
a result of Lenders holding disproportionate interests in the Loans, and
expressly consents to, and waives any claim based upon, such conflict of
interest.

         9.6 INDEMNIFICATION. Lenders agree to indemnify Agent (to the extent
not reimbursed by Borrower and without limiting the obligations of Borrower
hereunder), ratably according to their respective Pro Rata Shares, from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by, or asserted against
Agent in any way relating to or arising out of this Agreement or any other Loan
Document or any action taken or omitted by Agent in connection therewith;
PROVIDED, HOWEVER, that no Lender shall be liable for any portion of such
liabilities,



                                      -51-
<PAGE>   57


obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from Agent's gross negligence or willful
misconduct. Without limiting the foregoing, each Lender agrees to reimburse
Agent promptly upon demand for its ratable share of any out-of-pocket expenses
(including reasonable counsel fees) incurred by Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement
and each other Loan Document, to the extent that Agent is not reimbursed for
such expenses by Borrower and its Subsidiaries.

         9.7 Successor Agent. Agent may resign at any time by giving not less
than thirty (30) days' prior written notice thereof to Lenders and Borrower.
Upon any such resignation, the Requisite Lenders shall have the right to
appoint a successor Agent, which successor, absent the occurrence and
continuance of any Event of Default, shall be consented to by the Borrower
(such consent not to be unreasonably withheld or delayed). If no successor
Agent shall have been so appointed by the Requisite Lenders and shall have
accepted such appointment within 30 days after the resigning Agent's giving
notice of resignation, then the resigning Agent may, on behalf of Lenders,
appoint a successor Agent, which shall be a Lender, if a Lender is willing to
accept such appointment, or otherwise shall be a commercial bank or financial
institution or a subsidiary of a commercial bank or financial institution if
such commercial bank or financial institution is organized under the laws of
the United States of America or of any State thereof and has a combined capital
and surplus of at least $300,000,000. If no successor Agent has been appointed
pursuant to the foregoing, by the 30th day after the date such notice of
resignation was given by the resigning Agent, such resignation shall become
effective and the Requisite Lenders shall thereafter perform all the duties of
Agent hereunder until such time, if any, as the Requisite Lenders appoint a
successor Agent as provided above. Any successor Agent appointed by Requisite
Lenders hereunder shall be subject to the approval of Borrower, such approval
not to be unreasonably withheld or delayed; provided that such approval shall
not be required if a Default or an Event of Default shall have occurred and be
continuing. Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall succeed to and become vested with
all the rights, powers, privileges and duties of the resigning Agent. Upon the
earlier of the acceptance of any appointment as Agent hereunder by a successor
Agent or the effective date of the resigning Agent's resignation, the resigning
Agent shall be discharged from its duties and obligations under this Agreement
and the other Loan Documents, except that any indemnity rights or other rights
in favor of such resigning Agent shall continue. After any resigning Agent's
resignation hereunder, the provisions of this Section 9 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement and the other Loan Documents. Agent may be removed at the
written direction of the holders (other than Agent) of two-thirds or more of
the Commitments (excluding Agent's Commitment); provided that in so doing, such
Lenders shall be deemed to have waived and released any and all claims they may
have against Agent.

         9.8 SETOFF AND SHARING OF PAYMENTS. In addition to any rights now or
hereafter granted under applicable law and not by way of limitation



                                      -52-
<PAGE>   58


of any such rights, upon the occurrence and during the continuance of any Event
of Default, each Lender and each holder of any Note is hereby authorized at any
time or from time to time, without notice to Borrower or any of its
Subsidiaries or to any other Person, any such notice being hereby expressly
waived, to set off and to appropriate and to apply any and all balances held by
it at any of its offices for the account of Borrower or any of its Subsidiaries
(regardless of whether such balances are then due to Borrower) and any other
properties or assets any time held or owing by that Lender or that holder to or
for the credit or for the account of Borrower or any of its Subsidiaries
against and on account of any of the Obligations which are not paid when due.
Any Lender or holder of any Note exercising a right to set off or otherwise
receiving any payment on account of the Obligations in excess of its Pro Rata
Share thereof shall purchase for cash (and the other Lenders or holders shall
sell) such participations in each such other Lender's or holder's Pro Rata
Share of the Obligations as would be necessary to cause such Lender to share
the amount so set off or otherwise received with each other Lender or holder in
accordance with their respective Pro Rata Shares. Borrower and each of its
Subsidiaries agree, to the fullest extent permitted by law, that (a) any Lender
or holder may exercise its right to set off with respect to amounts in excess
of its Pro Rata Share of the Obligations and may sell participations in such
amount so set off to other Lenders and holders and (b) any Lender or holders so
purchasing a participation in the Loans made or other Obligations held by other
Lenders or holders may exercise all rights of set-off, bankers' lien,
counterclaim or similar rights with respect to such participation as fully as
if such Lender or holder were a direct holder of the Loans and the other
Obligations in the amount of such participation. Notwithstanding the foregoing,
if all or any portion of the set-off amount or payment otherwise received is
thereafter recovered from the Lender that has exercised the right of set-off,
the purchase of participations by that Lender shall be rescinded and the
purchase price restored without interest.

         9.9 ADVANCES; PAYMENTS; NON-FUNDING LENDERS; INFORMATION; ACTIONS IN
CONCERT.

         (a) ADVANCES; PAYMENTS. (i) Revolving Lenders shall refund or
participate in the Swing Line Loan in accordance with clauses (iii) and (iv) of
Section 1.1(c). If the Swing Line Lender declines to make a Swing Line Loan or
if Swing Line Availability is zero, the Agent shall promptly upon receipt of
any Notice of Revolving Credit Advance or L/C Request, forward a copy of such
request to each of the Lenders. Each Lender shall make the amount of such
Lender's Pro Rata Share of each Advance available to Agent in same day funds by
wire transfer to Agent's account as set forth in Annex F not later than 12:00
noon (New York time) on the requested funding date. After receipt of such wire
transfers (or, in the Agent's sole discretion, before receipt of such wire
transfers), subject to the terms hereof, Agent shall make the requested Advance
to Borrower. All payments by each Lender shall be made without setoff,
counterclaim or deduction of any kind.

         (ii) Upon the receipt of any payment from the Borrower with respect to
any Obligation (other than the Swing Line Loan), Agent will advise each Lender
by telephone, or telecopy of the amount of such Lender's Pro Rata Share of
principal, interest and Fees paid for the benefit of Lenders with respect to
each



                                      -53-
<PAGE>   59


applicable Loan. Provided that such Lender has made all payments required to be
made by it under this Agreement and the other Loan Documents as of such
Settlement Date, Agent will pay to each Lender such Lender's Pro Rata Share of
principal, interest and Fees paid by Borrower since the previous Settlement
Date for the benefit of that Lender on the Loans held by it. Such payments
shall be made by wire transfer to such Lender's account (as specified by such
Lender in Annex F or the applicable Assignment Agreement) not later than 3:00
p.m. (New York time) on the Business Day of such receipt.

         (b) AVAILABILITY OF LENDER'S PRO RATA SHARE. Agent may assume that
each Lender will make its Pro Rata Share of each Revolving Credit Advance
available to Agent on each funding date. If such Pro Rata Share is not, in
fact, paid to Agent by such Lender when due, Agent will be entitled to recover
such amount on demand from such Lender without set-off, counterclaim or
deduction of any kind. If any Lender fails to pay the amount of its Pro Rata
Share forthwith upon Agent's demand, Agent shall promptly notify Borrower and
Borrower shall immediately repay such amount to Agent. Nothing in this Section
9.9(b) or elsewhere in this Agreement or the other Loan Documents shall be
deemed to require Agent to advance funds on behalf of any Lender or to relieve
any Lender from its obligation to fulfill its Commitments hereunder or to
prejudice any rights that Borrower may have against any Lender as a result of
any default by such Lender hereunder. To the extent that Agent advances funds
to Borrower on behalf of any Lender and is not reimbursed therefor on the same
Business Day as such Advance is made, Agent shall be entitled to retain for its
account all interest accrued on such Advance until reimbursed by the applicable
Lender.

         (c) RETURN OF PAYMENTS. (i) If Agent pays an amount to a Lender under
this Agreement in the belief or expectation that a related payment has been or
will be received by Agent from Borrower and such related payment is not
received by Agent, then Agent will be entitled to recover such amount from such
Lender on demand without set-off, counterclaim or deduction of any kind.

         (ii) If Agent determines at any time that any amount received by Agent
    under this Agreement must be returned to Borrower or paid to any other
    Person pursuant to any insolvency law or otherwise, then, notwithstanding
    any other term or condition of this Agreement or any other Loan Document,
    Agent will not be required to distribute any portion thereof to any Lender.
    In addition, each Lender will repay to Agent on demand any portion of such
    amount that Agent has distributed to such Lender, together with interest at
    such rate, if any, as Agent is required to pay to Borrower or such other
    Person, without set-off, counterclaim or deduction of any kind.

         (d) NON-FUNDING LENDERS. The failure of any Lender (such Lender, a
"Non-Funding Lender") to make any Revolving Credit Advance or to purchase any
participation in any Swing Line Loan to be made or purchased by it on the date
specified therefor shall not relieve any other Lender (each such other Lender,
an "Other Lender") of its obligations to make such Advance, but neither any
Other Lender nor Agent shall be responsible for the failure of any Non-Funding



                                      -54-
<PAGE>   60


Lender to make an Advance to be made by such Non-Funding Lender, and no
Non-Funding Lender shall have any obligation to Agent or any Other Lender for
the failure by such Non-Funding Lender. Notwithstanding anything set forth
herein to the contrary, a Non- Funding Lender shall not have any voting or
consent rights under or with respect to any Loan Document or constitute a
"Lender" or a "Lender" (or be included in the calculation of "Requisite
Lenders" hereunder) for any voting or consent rights under or with respect to
any Loan Document.

         (e) DISSEMINATION OF INFORMATION. Agent will use reasonable efforts to
provide Lenders with any notice of Default or Event of Default received by
Agent from, or delivered by Agent to, any Credit Party, with notice of any
Event of Default of which Agent has actually become aware and with notice of
any action taken by Agent following any Event of Default; provided, however,
that Agent shall not be liable to any Lender for any failure to do so, except
to the extent that such failure is attributable to Agent's gross negligence or
willful misconduct. Lenders acknowledge that Borrower is required to provide
Financial Statements to Lenders in accordance with Annex D hereto and agree
that Agent shall have no duty to provide the same to Lenders.

         (f) ACTIONS IN CONCERT. Anything in this Agreement to the contrary
notwithstanding, each Lender hereby agrees with each other Lender that no
Lender shall take any action to protect or enforce its rights arising out of
this Agreement or the Notes (including exercising any rights of set-off)
without first obtaining the prior written consent of Agent or Requisite
Lenders, it being the intent of Lenders that any such action to protect or
enforce rights under this Agreement and the Notes shall be taken in concert and
at the direction or with the consent of Agent.

constitute the complete agreement between the parties with respect to the
subject matter thereof and may not be modified, altered or amended except as
set forth in Section 11.2 below. Any letter of interest, commitment letter, fee
letter (other than the GE Capital Fee Letter) or confidentiality agreement
between any Credit Party and Agent or any Lender or any of their respective
affiliates, predating this Agreement and relating to a financing of
substantially similar form, purpose or effect shall be superseded by this
Agreement.

         11.2 AMENDMENTS AND WAIVERS. (a) Except for actions expressly
permitted to be taken by Agent, no amendment, modification, termination or
waiver of any provision of this Agreement or any of the Notes or any other Loan
Documents, or any consent to any departure by any Credit Party therefrom, shall
in any event be effective unless the same shall be in writing and signed by
Borrower and by Requisite Lenders, Supermajority Lenders or all Lenders, as
applicable. Except as set forth in clauses (b) and (c) below, all such
amendments, modifications, terminations or waivers requiring the consent of any
Lenders shall require the written consent of Requisite Lenders.

         (b) No amendment, modification, termination or waiver of or consent
with respect to any provision of this Agreement which waives compliance with
the provisions of Section 6.10, or modifies any of the definitions of the terms
used in such Sections shall be effective unless the same shall be in writing
and signed by the Supermajority Lenders and Borrower.

         (c) No amendment, modification, termination or waiver shall, unless in
writing and signed by each Lender, do any of the following: (i) increase the
principal amount of any Lender's Commitment or subject the Lenders to any
additional monetary obligation; (ii) reduce the principal of, rate of interest
on or Fees payable with respect to any Loan or Letter of Credit Obligations;

Lenders or any of them to take any action hereunder; and (vii) amend or waive
this Section 11.2 or the definitions of the term "Requisite Lenders" or
"Supermajority Lenders" insofar as such definitions affect the substance of
this Section 11.2. Furthermore, no amendment, modification, termination or
waiver affecting the rights or duties of Agent or any L/C Issuer under this
Agreement or any other Loan Document shall be effective unless in writing and
signed by Agent or such L/C Issuer, as applicable, in addition to Lenders
required hereinabove to take such action. Each amendment, modification,
termination or waiver shall be effective only in the specific instance and for
the specific purpose for which it was given. No amendment, modification,
termination or waiver shall be required for Agent



                                      -56-
<PAGE>   62


to take additional Collateral pursuant to any Loan Document. No amendment,
modification, termination or waiver of any provision of any Note shall be
effective without the written concurrence of the holder of that Note. No notice
to or demand on any Credit Party in any case shall entitle such Credit Party or
any other Credit Party to any other or further notice or demand in similar or
other circumstances. Any amendment, modification, termination, waiver or
consent effected in accordance with this Section 11.2 shall be binding upon
each holder of the Notes at the time outstanding and each future holder of the
Notes.

         (d) If, in connection with any proposed amendment, modification,
waiver or termination (a "Proposed Change") requiring the consent of all
Lenders or the Supermajority Lenders, the consent of Requisite Lenders is
obtained, but the consent of other Lenders whose consent is required is not
obtained (any such Lender whose consent is not obtained being referred to as a
"Non-Consenting Lender") then, so long as Agent is not a Non-Consenting Lender,
at Borrower's request Agent, or a Person acceptable to Agent, shall have the
right with Agent's consent and in Agent's sole discretion (but shall have no
obligation) to purchase from such Non-Consenting Lenders, and such
Non-Consenting Lenders agree that they shall, upon Agent's request, sell and
assign to Agent or such Person, all of the Commitments of such Non-Consenting
Lender for an amount equal to the principal balance of all Loans held by the
Non-Consenting Lender and all accrued interest and Fees with respect thereto
through the date of sale, such purchase and sale to be consummated pursuant to
an executed Assignment Agreement.

         (e) Upon indefeasible payment in full in cash and performance of all
of the Obligations (other than indemnification Obligations under Section 1.10),
termination of the Commitments and a release of all claims against Agent and
Lenders, and so long as no suits, actions proceedings, or claims are pending or
threatened against any Indemnified Person asserting any damages, losses or
liabilities that are Indemnified Liabilities, Agent shall deliver to Borrower
termination statements, mortgage releases and other documents necessary or
appropriate to evidence the termination of the Liens securing payment of the
Obligations.

         11.3 FEES AND EXPENSES. Borrower shall reimburse Agent for all
out-of-pocket expenses incurred in connection with the preparation of the Loan
Documents (including the reasonable fees and expenses of all of its special
loan counsel, advisors, consultants and auditors retained in connection with
the Loan Documents and the Related Transactions and advice in connection
therewith). Borrower shall reimburse Agent (and, with respect to clauses (c)
and (d) below, all Lenders) for all fees, costs and expenses, including the
fees, costs and expenses of counsel or other advisors (including environmental
and management consultants and appraisers) for advice, assistance, or other
representation in connection with:

         (a) the forwarding to Borrower or any other Person on behalf of
Borrower by Agent of the proceeds of the Loans;

         (b) any amendment, modification or waiver of, or consent with respect
to, any of the Loan Documents or Related Transactions Documents or advice in
connection with the administration of the Loans made pursuant hereto or its
rights hereunder or thereunder;



                                      -57-
<PAGE>   63


         (c) any litigation, contest, dispute, suit, proceeding or action
(whether instituted by Agent, any Lender, Borrower or any other Person) in any
way relating to the Collateral, any of the Loan Documents or any other
agreement to be executed or delivered in connection therewith or herewith,
whether as party, witness, or otherwise, including any litigation, contest,
dispute, suit, case, proceeding or action, and any appeal or review thereof, in
connection with a case commenced by or against Borrower or any other Person
that may be obligated to Agent by virtue of the Loan Documents; including any
such litigation, contest, dispute, suit, proceeding or action arising in
connection with any work-out or restructuring of the Loans during the pendency
of one or more Events of Default; provided that in the case of reimbursement of
counsel for Lenders other than Agent, such reimbursement shall be limited to
one counsel for all such Lenders;

         (d) any attempt to enforce any remedies of Agent or any Lender against
any or all of the Credit Parties or any other Person that may be obligated to
Agent or any Lender by virtue of any of the Loan Documents; including any such
attempt to enforce any such remedies in the course of any work-out or
restructuring of the Loans during the pendency of one or more Events of
Default; provided that in the case of reimbursement of counsel for Lenders
other than Agent, such reimbursement shall be limited to one counsel for all
such Lenders;

         (e) any work-out or restructuring of the Loans during the pendency of
one or more Events of Default;

         (f) efforts to verify, protect, evaluate and assess and (following the
occurrence of any Event of Default) to appraise, collect, sell, liquidate or
otherwise dispose of any of the Collateral; including all attorneys' and other
professional and service providers' fees arising from such services, including
those in connection with any appellate proceedings; and all expenses, costs,
charges and other fees incurred by such counsel and others in any way or
respect arising in connection with or relating to any of the events or actions
described in this Section 11.3 shall be payable, on demand, by Borrower to
Agent. Without limiting the generality of the foregoing, such expenses, costs,
charges and fees may include: fees, costs and expenses of accountants,
environmental advisors, appraisers, investment bankers, management and other
consultants and paralegals; court costs and expenses; photocopying and
duplication expenses; court reporter fees, costs and expenses; long distance
telephone charges; air express charges; telegram or telecopy charges;
secretarial overtime charges; and expenses for travel, lodging and food paid or
incurred in connection with the performance of such legal or other advisory
services.

         11.4 NO WAIVER. Agent's or any Lender's failure, at any time or times,
to require strict performance by the Credit Parties of any provision of this
Agreement and any of the other Loan Documents shall not waive, affect or
diminish any right of Agent or such Lender thereafter to demand strict
compliance and performance therewith. Any suspension or waiver of an Event of
Default shall not suspend, waive or affect any other Event of Default whether
the same is prior or subsequent thereto and whether the same or of a



                                      -58-
<PAGE>   64


different type. Subject to the provisions of Section 11.2, none of the
undertakings, agreements, warranties, covenants and representations of any
Credit Party contained in this Agreement or any of the other Loan Documents and
no Default or Event of Default by any Credit Party shall be deemed to have been
suspended or waived by Agent or any Lender, unless such waiver or suspension is
by an instrument in writing signed by an officer of or other authorized
employee of Agent and the applicable required Lenders and directed to Borrower
specifying such suspension or waiver.

         11.5 REMEDIES. Agent's and Lenders' rights and remedies under this
Agreement shall be cumulative and nonexclusive of any other rights and remedies
which Agent or any Lender may have under any other agreement, including the
other Loan Documents, by operation of law or otherwise. Recourse to the
Collateral shall not be required.

         11.6 SEVERABILITY. Wherever possible, each provision of this Agreement
and the other Loan Documents shall be interpreted in such a manner as to be
effective and valid under applicable law, but if any provision of this
Agreement shall be prohibited by or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or invalidity,
without invalidating the remainder of such provision or the remaining
provisions of this Agreement.

         11.7 CONFLICT OF TERMS. Except as otherwise provided in this Agreement
or any of the other Loan Documents by specific reference to the applicable
provisions of this Agreement, if any provision contained in this Agreement is
in conflict with, or inconsistent with, any provision in any of the other Loan
Documents, the provision contained in this Agreement shall govern and control.

         11.8 CONFIDENTIALITY. Agent and each Lender agree to use commercially
reasonable efforts (equivalent to the efforts Agent or such Lender applies to
maintain the confidentiality of its own confidential information) to maintain
as confidential all confidential information provided to them by the Credit
Parties and designated as confidential for a period of two (2) years following
receipt thereof, and further agree not to use such confidential information
except in connection with the evaluation and administration of the credit
relationship governed by this Agreement; except that Agent and each Lender may
disclose such information (a) to Persons employed or engaged by Agent or such
Lender in evaluating, approving, structuring or administering the Loans and the
Commitments who agree to be bound by the terms of this Section; (b) to any bona
fide assignee or participant or potential assignee or participant that has
agreed to comply with the covenant contained in this Section 11.8 (and any such
bona fide assignee or participant or potential assignee or participant may
disclose such information to Persons employed or engaged by them as described
in clause (a) above); (c) as required or requested by any Governmental
Authority or reasonably believed by Agent or such Lender to be compelled by any
court decree, subpoena or legal or administrative order or process; (d) as, in
the opinion of Agent's or such Lender's counsel, required by law; (e) in
connection with the exercise of any right or remedy under the Loan Documents or
in connection with any Litigation to which



                                      -59-
<PAGE>   65


Agent or such Lender is a party; or (f) which ceases to be confidential through
no fault of Agent or such Lender. The Agent and the Lenders acknowledge that
the confidential information may from time to time include material non-public
information relating to the Borrower or its Subsidiaries, including information
regarding potential Permitted Acquisitions.

         11.9 GOVERNING LAW. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN ANY OF
THE LOAN DOCUMENTS, IN ALL RESPECTS, INCLUDING ALL MATTERS OF CONSTRUCTION,
VALIDITY AND PERFORMANCE, THE LOAN DOCUMENTS AND THE OBLIGATIONS SHALL BE
GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED IN THAT STATE) AND
ANY APPLICABLE LAWS OF THE UNITED STATES OF AMERICA. BORROWER HEREBY CONSENTS
AND AGREES THAT THE STATE OR FEDERAL COURTS LOCATED IN THE BOROUGH OF MANHATTAN
IN THE CITY AND STATE OF NEW YORK SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND
DETERMINE ANY CLAIMS OR DISPUTES BETWEEN BORROWER, AGENT AND LENDERS PERTAINING
TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR TO ANY MATTER ARISING
OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS,
PROVIDED, THAT AGENT, LENDERS AND BORROWER ACKNOWLEDGE THAT ANY APPEALS FROM
THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE THE BOROUGH OF
MANHATTAN IN THE CITY AND STATE OF NEW YORK AND, PROVIDED, FURTHER NOTHING IN
THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE AGENT FROM BRINGING SUIT
OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO REALIZE ON THE
COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A JUDGMENT
OR OTHER COURT ORDER IN FAVOR OF AGENT. BORROWER EXPRESSLY SUBMITS AND CONSENTS
IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH
COURT, AND BORROWER HEREBY WAIVES ANY OBJECTION WHICH SUCH CREDIT PARTY MAY
HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON
CONVENIENS AND HEREBY CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE
RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT. BORROWER HEREBY WAIVES PERSONAL
SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION
OR SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINTS AND OTHER PROCESS
MAY BE MADE BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO BORROWER AT THE
ADDRESS SET FORTH IN ANNEX G OF THIS AGREEMENT AND THAT SERVICE SO MADE SHALL
BE DEEMED COMPLETED UPON THE EARLIER OF BORROWER'S ACTUAL RECEIPT THEREOF OR
THREE (3) DAYS AFTER DEPOSIT IN THE U.S. MAIL, PROPER POSTAGE PREPAID.

         11.10 NOTICES. Except as otherwise provided herein, whenever it is
provided herein that any notice, demand, request, consent, approval,
declaration or other communication shall or may be given to or served upon any
of the parties by any other parties, or whenever any of the parties desires to
give or serve upon any other parties any communication with respect to this
Agreement, each such notice, demand, request, consent, approval, declaration or
other communication shall be in writing and shall be deemed to have been
validly served, given or delivered (a) upon the earlier of actual receipt and
three (3) Business Days after deposit in the United States Mail, registered or
certified mail, return receipt requested, with proper postage prepaid, (b) upon
transmission, when sent by telecopy or other similar facsimile transmission
(with such telecopy or facsimile promptly confirmed by delivery of a copy by
personal delivery or United States Mail as otherwise provided in this Section
11.10), (c) one (1) Business Day after deposit with a reputable overnight
courier with all charges prepaid or (d) when delivered, if hand-delivered by
messenger, all of which shall be addressed to the party to be notified and sent
to the address or facsimile number indicated on Annex G or to such other
address (or facsimile number) as may be substituted by notice given as herein
provided. The giving of any notice required hereunder may be waived in writing
by the party entitled to receive such notice. Failure or delay in delivering
copies of any notice, demand, request, consent, approval, declaration or other
communication to any Person (other than Borrower or Agent) designated on Annex
G to receive copies shall in no way adversely affect the effectiveness of such
notice, demand, request, consent, approval, declaration or other communication.

         11.11 SECTION TITLES. The Section titles and Table of Contents
contained in this Agreement are and shall be without substantive meaning or
content of any kind whatsoever and are not a part of the agreement between the
parties hereto.

         11.12 COUNTERPARTS. This Agreement may be executed in any number of
separate counterparts, each of which shall collectively and separately
constitute one agreement. To the extent executed in counterparts, this
Agreement shall become effective when the Agent shall have notified the
Borrower that the Borrower's signature pages have been accepted by the Agent in
New York, New York.

         11.13 WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN CONNECTION
WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED
BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND
FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT
THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE,
TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF
ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER SOUNDING IN
CONTRACT, TORT OR



                               -61-
<PAGE>   67


OTHERWISE, AMONG AGENT, LENDERS AND BORROWER ARISING OUT OF, CONNECTED WITH,
RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED AMONG THEM IN
CONNECTION WITH, THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR THE
TRANSACTIONS RELATED THERETO.

         11.14 PRESS RELEASES. The Borrower agrees that neither it nor its
Affiliates will in the future issue any press releases or other public
disclosure using the name of GE Capital or its affiliates or referring to this
Agreement, the other Loan Documents or the Related Transactions Documents
without at least two (2) Business Days' prior notice to GE Capital and without
the prior written consent of GE Capital unless (and only to the extent that)
Borrower or its Affiliate is required to do so under law and then, in any
event, Borrower or its Affiliate will consult with GE Capital before issuing
such press release or other public disclosure. The Borrower consents to the
publication by Agent or any Lender of a tombstone or similar advertising
material relating to the financing transactions contemplated by this Agreement.

         11.15 REINSTATEMENT. This Agreement shall remain in full force and
effect and continue to be effective should any petition be filed by or against
Borrower for liquidation or reorganization, should Borrower become insolvent or
make an assignment for the benefit of any creditor or creditors or should a
receiver or trustee be appointed for all or any significant part of Borrower's
assets, and shall continue to be effective or to be reinstated, as the case may
be, if at any time payment and performance of the Obligations, or any part
thereof, is, pursuant to applicable law, rescinded or reduced in amount, or
must otherwise be restored or returned by any obligee of the Obligations,
whether as a "voidable preference," "fraudulent conveyance," or otherwise, all
as though such payment or performance had not been made. In the event that any
payment, or any part thereof, is rescinded, reduced, restored or returned, the
Obligations shall be reinstated and deemed reduced only by such amount paid and
not so rescinded, reduced, restored or returned.

         11.16 ADVICE OF COUNSEL. Each of the parties represents to each other
party hereto that it has discussed this Agreement and, specifically, the
provisions of Sections 11.9 and 11.13, with its counsel.

         11.17 NO STRICT CONSTRUCTION. The parties hereto have participated
jointly in the negotiation and drafting of this Agreement. In the event an
ambiguity or question of intent or interpretation arises, this Agreement shall
be construed as if drafted jointly by the parties hereto and no presumption or
burden of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any provisions of this Agreement.

         11.18 NO THIRD-PARTY BENEFICIARY. Borrower's covenants in Article 5,
to cause, or to use its reasonable best efforts to cause, the Managed Practices
to take certain actions, are not intended to: (i) imply that Borrower, or any
of its Subsidiaries, has the power and authority to control a Managed Practice;
(ii) constitute an assumption by Borrower of any obligations of a Managed
Practice to any Person; or (iii) waive or release any claim or cause of action
that Borrower or a Subsidiary may have against a Managed Practice for failing
to comply with any of such Managed Practice's obligations under a Service
Agreement.

                             ANNEX B (Section 1.2)
                                       to
                                CREDIT AGREEMENT

                               LETTERS OF CREDIT

         (a) ISSUANCE. Subject to the terms and conditions of the Agreement,
Agent and Lenders agree to incur, from time to time prior to the Commitment
Termination Date, upon the request of Borrower and for Borrower's account,
Letter of Credit Obligations by causing Letters of Credit to be issued (by a
bank or other legally authorized Person selected by or acceptable to Agent in
its sole discretion (each, an "L/C Issuer")) for Borrower's account and
guaranteed by Agent; provided, however, that if the L/C Issuer is a Lender,
then such Letters of Credit shall not be guaranteed by Agent but rather each
Lender shall, subject to the terms and conditions hereinafter set forth,
purchase (or be deemed to have purchased) risk participations in all such
Letters of Credit issued with the written consent of Agent, as more fully
described in paragraph (b)(ii) below. The aggregate amount of all such Letter
of Credit Obligations shall not at any time exceed the least of (i) Ten Million
Dollars ($10,000,000.00) (the "L/C Sublimit"), (ii) the Maximum Amount less the
aggregate outstanding principal balance of the Revolving Credit Advances and
the Swing Line Loan, and (iii) the Revolving Credit Availability less the
aggregate outstanding principal balance of the Revolving Credit Advances and
the Swing Line Loan. No such Letter of Credit shall have an expiry date which
is more than one year following the date of issuance thereof, and neither Agent
nor Lenders shall be under any obligation to incur Letter of Credit Obligations
in respect of, or purchase risk participations in, any Letter of Credit having
an expiry date which is later than the Commitment Termination Date.

         (b) (i) ADVANCES AUTOMATIC; PARTICIPATIONS. In the event that Agent or
any Lender shall make any payment on or pursuant to any Letter of Credit
Obligation, such payment shall then be deemed automatically to constitute a
Revolving Credit Advance under Section 1.1(a) of the Agreement regardless of
whether a Default or Event of Default shall have occurred and be continuing and
notwithstanding Borrower's failure to satisfy the conditions precedent set
forth in Section 2, and each Lender shall be obligated to pay its Pro Rata
Share thereof in accordance with the Agreement. The failure of any Lender to
make available to Agent for Agent's own account its Pro Rata Share of any such
Revolving Credit Advance or payment by Agent under or in respect of a Letter of
Credit shall not relieve any other Lender of its obligation hereunder to make
available to Agent its Pro Rata Share thereof, but no Lender shall be
responsible for the failure of any other Lender to make available such other
Lender's Pro Rata Share of any such payment.

          (ii) If it shall be illegal or unlawful for Borrower to incur
     Revolving Credit Advances as contemplated by paragraph (b)(i) above
     because of an Event of Default described in Section 8.1(h) or (i) or
     otherwise or if it shall be illegal or unlawful for any Lender to be
     deemed to have assumed a ratable share of the reimbursement obligations
     owed to an L/C Issuer, or if the L/C Issuer is a Lender, then (i)
     immediately and without further action whatsoever, each Lender shall be
     deemed to have irrevocably



                              B-1
<PAGE>   98


     and unconditionally purchased from Agent (or such L/C Issuer, as the case
     may be) an undivided interest and participation equal to such Lender's Pro
     Rata Share (based on the Revolving Loan Commitments) of the Letter of
     Credit Obligations in respect of all Letters of Credit then outstanding
     and (ii) thereafter, immediately upon issuance of any Letter of Credit,
     each Lender shall be deemed to have irrevocably and unconditionally
     purchased from Agent (or such L/C Issuer, as the case may be) an undivided
     interest and participation in such Lender's Pro Rata Share (based on the
     Revolving Loan Commitments) of the Letter of Credit Obligations with
     respect to such Letter of Credit on the date of such issuance. Each Lender
     shall fund its participation in all payments or disbursements made under
     the Letters of Credit in the same manner as provided in the Agreement with
     respect to Revolving Credit Advances.

         (c) CASH COLLATERAL. If Borrower is required to provide cash
collateral for any Letter of Credit Obligations pursuant to the Agreement prior
to the Commitment Termination Date, Borrower will pay to Agent for the benefit
of Lenders cash or cash equivalents acceptable to Agent ("Cash Equivalents") in
an amount equal to 105% of the maximum amount then available to be drawn under
each applicable Letter of Credit outstanding. Such funds or Cash Equivalents
shall be held by Agent in a cash collateral account (the "Cash Collateral
Account") maintained at a bank or financial institution acceptable to Agent.
The Cash Collateral Account shall be in the name of Borrower and shall be
pledged to, and subject to the control of, Agent, for the benefit of Agent and
Lenders, in a manner satisfactory to Agent. Borrower hereby pledges and grants
to Agent, on behalf of Lenders, a security interest in all such funds and Cash
Equivalents held in the Cash Collateral Account from time to time and all
proceeds thereof, as security for the payment of all amounts due in respect of

due. The Agreement, including this Annex B, shall constitute a security
agreement under applicable law.

         If any Letter of Credit Obligations, whether or not then due and
payable, shall for any reason be outstanding on the Commitment Termination
Date, Borrower shall either (i) provide cash collateral therefor in the manner
described above, or (ii) cause all such Letters of Credit and guaranties
thereof to be canceled and returned, or (iii) deliver a stand-by letter (or
letters) of credit in guarantee of such Letter of Credit Obligations, which
stand-by letter (or letters) of credit shall be of like tenor and duration as,

discretion.

Account by Borrower, whether before or after the Commitment Termination Date,
Agent may apply such funds or Cash Equivalents then held in the Cash Collateral
Account to the payment of any amounts, in such order as Agent may elect, as
shall be or shall become due and payable by Borrower to Lenders with respect to
such Letter of Credit Obligations of Borrower and, upon the satisfaction in
full of all Letter of Credit

Obligations of Borrower, to any other Obligations then due and payable.

         Neither Borrower nor any Person claiming on behalf of or through
Borrower shall have any right to withdraw any of the funds or Cash Equivalents
held in the Cash Collateral Account, except that upon the termination of all
Letter of Credit Obligations and the payment of all amounts payable by Borrower
to Lenders in respect thereof, any funds remaining in the Cash Collateral
Account shall be applied to other Obligations when due and owing and upon
payment in full of such Obligations, any remaining amount shall be paid to
Borrower or as otherwise required by law; provided that, prior to the
Commitment Termination Date and absent the occurrence and continuation of an
Event of Default, any amounts remaining in the Cash Collateral account upon the
termination of all Letter of Credit Obligations and the payment of all amounts
payable by Borrower to Lenders in respect thereof shall be returned to the
Borrower upon the Borrower's request therefor.

         (d) FEES AND EXPENSES. Borrower agrees to pay to Agent for the benefit
of Lenders, as compensation to such Lenders for Letter of Credit Obligations

on account of such Letter of Credit Obligations, and (y) for each month during
which any Letter of Credit Obligation shall remain outstanding, a fee (the

time to time in effect multiplied by the daily average the amount undrawn under
the Letter of Credit for such month. The Letter of Credit Fee shall be paid to
Agent for the benefit of the Lenders in arrears, on the first day of each
month. In addition, Borrower shall pay to any L/C Issuer, on demand, such fees
(including all per annum fees), charges and expenses of such L/C Issuer in
respect of the issuance, negotiation, acceptance, amendment, transfer and
payment of such Letter of Credit or otherwise payable pursuant to the
application and related documentation under which such Letter of Credit is
issued.

         (e) REQUEST FOR INCURRENCE OF LETTER OF CREDIT OBLIGATIONS. Borrower
shall give Agent at least five (5) Business Days prior written notice (the "L/C
Request") requesting the incurrence of any Letter of Credit Obligation,
specifying the date such Letter of Credit Obligation is to be incurred,
identifying the beneficiary to which such Letter of Credit Obligation relates
and describing the nature of the transactions proposed to be supported thereby.
The notice shall be accompanied by the form of the Letter of Credit (which
shall be acceptable to the L/C Issuer) to be guarantied. Notwithstanding
anything contained herein to the contrary, Letter of Credit applications by
Borrower and approvals by Agent may be made and transmitted pursuant to
electronic codes and security measures mutually agreed upon and established by
and among Borrower, Agent and the L/C Issuer.

         (f) OBLIGATION ABSOLUTE. The obligation of Borrower to reimburse Agent
and Lenders for payments made with respect to any Letter of Credit Obligation

     which Borrower or any of its Affiliates or any Lender may at any time have
     against a beneficiary or any transferee of any Letter of Credit (or any
     Persons or entities for whom any such transferee may be acting), Agent,
     any Lender, or any other Person, whether in connection with the Agreement,
     the Letter of Credit, the transactions contemplated herein or therein or
     any unrelated transaction (including any underlying transaction between
     Borrower or any of its Affiliates and the beneficiary for which the Letter
     of Credit was procured);

          (iii) any draft, demand, certificate or any other document presented
     under any Letter of Credit proving to be forged, fraudulent, invalid or
     insufficient in any respect or any statement therein being untrue or
     inaccurate in any respect;

          (iv) payment by Agent (except as otherwise expressly provided in
     paragraph (g)(ii)(C) below) or any L/C Issuer under any Letter of Credit
     or guaranty thereof against presentation of a demand, draft or certificate
     or other document which does not comply with the terms of such Letter of
     Credit or such guaranty;

          (v) any other circumstance or happening whatsoever, which is similar
     to any of the foregoing; or

          (vi) the fact that a Default or an Event of Default shall have
     occurred and be continuing.

         (g) Indemnification; Nature of Lenders' Duties. (i) In addition to
amounts payable as elsewhere provided in the Agreement, Borrower hereby agrees
to pay and to protect, indemnify, and save harmless Agent and each Lender from
and against any and all claims, demands, liabilities, damages, losses, costs,
charges and expenses (including attorneys' fees and allocated costs of internal
counsel) which Agent or any Lender may incur or be subject to as a consequence,
direct or indirect, of (A) the issuance of any Letter of Credit or guaranty
thereof, or (B) the failure of Agent or any Lender seeking indemnification or
of any L/C Issuer to honor a demand for payment under any Letter of Credit or
guaranty thereof as a result of any act or omission, whether rightful or
wrongful, of any present or future de jure or de facto government or
Governmental Authority, in each case other than to the extent resulting from
the gross negligence or willful misconduct of Agent or such Lender (as finally
determined by a court of competent jurisdiction).

          (ii) As between Agent and any Lender and Borrower, Borrower assumes
     all risks of the acts and omissions of, or misuse of any Letter of Credit
     by beneficiaries of any Letter of Credit. In furtherance and not in

<PAGE>   101


     neither Agent nor any Lender shall be responsible: (A) for the form,
     validity, sufficiency, accuracy, genuineness or legal effect of any
     document issued by any party in connection with the application for and
     issuance of any Letter of Credit, even if it should in fact prove to be in
     any or all respects invalid, insufficient, inaccurate, fraudulent or
     forged; (B) for the validity or sufficiency of any instrument transferring
     or assigning or purporting to transfer or assign any Letter of Credit or
     the rights or benefits thereunder or proceeds thereof, in whole or in
     part, which may prove to be invalid or ineffective for any reason other
     than, only in the case of a purported transfer of the entire Letter of
     Credit and not a right to draw or receive payment thereunder, the fact
     that the instrument purports to transfer a Letter of Credit which states
     on its face that it is non-transferable; (C) for failure of the
     beneficiary of any Letter of Credit to comply fully with conditions
     required in order to demand payment under such Letter of Credit; provided
     that, in the case of any payment by Agent or L/C Issuer under any Letter
     of Credit or guaranty thereof, Agent or such L/C Issuer, as the case may
     be, shall be liable to the extent such payment was made as a result of its
     gross negligence or willful misconduct (as finally determined by a court
     of competent jurisdiction) in determining that the demand for payment
     under such Letter of Credit or guaranty thereof complies on its face with
     any applicable requirements for a demand for payment under such Letter of
     Credit or guaranty thereof; (D) for errors, omissions, interruptions or
     delays in transmission or delivery of any messages, by mail, cable,
     telegraph, telex or otherwise, whether or not they be in cipher; (E) for
     errors in interpretation of technical terms; (F) for any loss or delay in
     the transmission or otherwise of any document required in order to make a
     payment under any Letter of Credit or guaranty thereof or of the proceeds
     thereof; (G) for the credit of the proceeds of any drawing under any
     Letter of Credit or guaranty thereof; and (H) for any consequences arising
     from causes beyond the control of Agent or any Lender. None of the above
     shall affect, impair, or prevent the vesting of any of Agent's or any
     Lender's rights or powers hereunder or under the Agreement.

          (iii) Nothing contained herein shall be deemed to limit or to expand
     any waivers, covenants or indemnities made by Borrower in favor of any L/C
     Issuer in any letter of credit application, reimbursement agreement or
     similar document, instrument or agreement between Borrower and such L/C
     Issuer.

          (iv) Nothing contained herein shall waive, release or limit the
     Borrower's rights, claims and remedies as against any beneficiary of a
     Letter of Credit.

                             ANNEX E (Section 6.10)
                                       to
                                CREDIT AGREEMENT

                              FINANCIAL COVENANTS


         Borrower shall not breach or fail to comply with any of the following
financial covenants, each of which shall be calculated in accordance with GAAP:

         (a) MINIMUM FIXED CHARGE COVERAGE RATIO. Each of (i) the Borrower and
its Restricted Subsidiaries and (ii) the Borrower and its Subsidiaries, shall
have on a consolidated basis at the end of each Fiscal Quarter set forth below,
a Fixed Charge Coverage Ratio for the number of Fiscal Quarters ended since the
Closing Date, or, if the number of Fiscal Quarters ended since the Closing Date
exceeds 4 quarters, then for the four (4) Fiscal Quarters then ended, of not
less than the following for each of the following periods:

                          Period                               Ratio
                          ------                               -----
     Fiscal Quarter ending September 30, 1997
       through the Fiscal Quarter ending June 30, 2000;     2.65 to 1.00

     Fiscal Quarter ending September 30, 2000; and          1.35 to 1.00
       each Fiscal Quarter ended thereafter                 1.10 to 1.00

         (b) MAXIMUM LEVERAGE RATIO. Each of (i) the Borrower and its
Restricted Subsidiaries and (ii) the Borrower and its Subsidiaries, on a
consolidated basis shall have, at the end of each Fiscal Quarter a Total Debt
Leverage Ratio not in excess of 4.0 to 1.0.

         (c) MAXIMUM SENIOR DEBT LEVERAGE RATIO. Each of (i) the Borrower and
its Restricted Subsidiaries and (ii) the Borrower and its Subsidiaries, on a
consolidated basis shall have at the end of each Fiscal Quarter a Senior Debt
Leverage Ratio not in excess of 3.0 to 1.0.

         (d) PRO FORMA ADJUSTMENTS. In calculating quarterly compliance with
the covenants specified in paragraphs (a), (b) and (c) above, the following
adjustments shall be made to reflect the effect of acquisitions, dispositions
and terminations of Service Agreements (which are not contemporaneously
replaced by Service Agreements with the same Managed Practices and which new
agreements provide substantially the same EBITDA to the Borrower and its
Subsidiaries as the terminated Service Agreements) occurring after the Closing
Date and during the relevant test period:

          (i) For the purposes of paragraphs (a), (b) and (c) the EBITDA
     attributable to such acquisition, based on the actual EBITDA of such
     acquired entity for such period, shall be included as if such entity had
     been acquired on the first day of such period but shall be adjusted to
     reflect the APPI Physician compensation model, and shall be adjusted to
     eliminate, as of the first day of such period, any Indebtedness repaid,
     retired, disposed of or refinanced in



                                      E-1
<PAGE>   109


     such acquisition and to include any Indebtedness incurred in connection
     with such acquisition (including any portion thereof used to fund the
     aforementioned refinancing);

          (ii) For the purposes of paragraph (a), Fixed Charges shall include,
     as of the first day of such period and for the entire period, any Fixed
     Charges associated with any acquired entity, including, any interest
     attributable to any Indebtedness incurred in connection with such
     acquisition, but excluding any interest or other Fixed Charges
     attributable to any Indebtedness repaid, retired, disposed of or
     refinanced in such acquisition (including any portion thereof used to fund
     the aforementioned refinancing);

          (iii) For the purposes of paragraph (a), for any test period which
     occurs prior to the date when four (4) Fiscal Quarters have ended since
     the Closing Date, and that requires adjustments pursuant to clauses (i)
     and (ii) above, the Fixed Charge Coverage Ratio shall be calculated by
     annualizing the results for the Company and its Subsidiaries before making
     the adjustments referred to in such clauses and then making the adjustment
     described in such clauses based on the actual results of the newly
     acquired entities for the four (4) quarters ended as of the end of the
     relevant test period; and

          (iv) For the purposes of paragraphs (b) and (c), Indebtedness and
     Senior Debt of the Borrower and its Subsidiaries shall be adjusted (A)
     upward to reflect any Indebtedness or Senior Debt incurred or assumed in
     connection with such acquisition or disposition and (B) downward to
     reflect any Indebtedness or Senior Debt repaid, retired or disposed of in
     connection with such acquisition, disposition or Service Agreement
     termination to the extent that the Borrower and/or its Subsidiaries have
     been released from all liability therefor.

          (v) For the purposes of paragraphs (a), (b) and (c), the EBITDA
     attributable to any entity all or substantially all of whose Stock or
     assets were disposed of or to any terminated Service Agreement shall be
     excluded as if such entity had been disposed of, or such Service Agreement
     terminated, on the first day of such period and shall be adjusted to
     eliminate, as of the first day of such period, any Indebtedness repaid,
     retired or disposed of in connection with such disposition or termination
     to the extent that the Borrower and/or the remaining Subsidiaries have
     been released from all liability therefor.

          (vi) For the purposes of paragraph (a), Fixed Charges shall exclude,
     as of the first day of such period and for the entire period, any Fixed
     Charges associated with any entity disposed of or with any terminated
     Service Agreement, including, any interest or other Fixed Charges
     attributable to any Indebtedness repaid, retired or disposed of in such
     disposition or termination, to the extent that the Borrower and/or the
     remaining Subsidiaries have been released from all liability therefor.

         (e) CERTAIN OTHER ADJUSTMENTS. In calculating the covenants for the
Borrower and its Restricted Subsidiaries above: (i) EBITDA shall be calculated
so as to exclude all items



                                      E-2
<PAGE>   110


included in EBITDA with respect to any Permitted Joint Venture or any
Unrestricted Subsidiary; (ii) Fixed Charges shall be calculated to exclude any
such amounts attributable to any Permitted Joint Venture or any Unrestricted
Subsidiary; and (iii) Senior Debt and Indebtedness of the Borrower and its
Restricted Subsidiaries shall not include any Indebtedness of any Unrestricted
Subsidiary or that constitutes Permitted Recourse Debt.
