information in this Prospectus assumes: (i) a 0.314-for-1 stock split with
respect to the Common Stock and Non-Voting Common Stock (the "Reverse Stock

Series B Redeemable Convertible Preferred Stock, Series B Non-Voting Redeemable

                                  THE COMPANY
   
  Physician Health Corporation is a physician management company focusing on
the value-added integration of practice management, ancillary health care
services, network development and administration, and payor contracting in
selected markets. As of December 31, 1997, the Company provided payor contract
administration and related services to 25 physician networks, one of which is
owned by the Company, one of which is a nonprofit corporation of which the
Company is the sole member (together, the "PHC Networks") and the remainder of
which are independent entities that receive services from the Company (the
"Affiliated Networks"). The PHC Networks and Affiliated Networks included
approximately 3,300 physicians and 2.3 million covered lives under 29 managed
care contracts including specialty capitated and global risk contracts. As of
December 31, 1997, the Company provided practice management services to 34
physician practices ("PHC Practices") including 171 physicians ("PHC
Physicians"). The Company was a party to practice management agreements with 26
of the PHC Practices that employed 113 PHC Physicians. The Company directly
owned and operated the remaining eight PHC Practices through which it directly
employed 58 PHC Physicians.     
   
  The Company's objective is to continue building comprehensive and integrated
networks of physicians in selected regional markets in order to: (i) establish
a significant market presence enabling it to negotiate favorable payor
contracts and (ii) provide a broad range of physicians and ancillary health
care services to payors and patients. To achieve these objectives, the Company
seeks to: (a) leverage contracting expertise to enhance its strategic position
in its markets; (b) selectively acquire key practices to strengthen market
presence; (c) provide management expertise and capital for development of
ancillary health care services; (d) negotiate and administer beneficial payor
contracts; and (e) utilize information technology to improve practice
performance and meet payor requirements and patient needs. The Company believes
that the expertise of its management team in network development, payor
contracting and ancillary health care services, as well as PHC's flexible
approach to entering new markets and structuring its operations, differentiate
PHC from traditional physician practice management companies ("PPMs") and
enhance its ability to attract physicians and to negotiate favorable payor
contracts. PHC's acquisition of key practices is a part of its overall strategy
of strengthening its networks and market presence and enhancing the Company's
ability to contract with managed care payors and providers.     
   
  The Company commenced operations in 1994 as a wholly-owned subsidiary (the
"Predecessor") of Surgical Health Corporation. PHC was incorporated in Delaware
in August 1995 and acquired the Predecessor in November 1995. Prior to the
acquisition of the first PHC Practice in November 1996, the Company principally
engaged in network development and administration, payor contracting, practice
administration, and development activities related to potential acquisitions.
The Company's current regional markets are centered in Atlanta, Georgia;
Cincinnati, Ohio; Dallas/Ft. Worth, Texas; Memphis, Tennessee; Orlando,
Florida; and St. Louis, Missouri. The Company will continue to evaluate
expansion into additional regional markets. The principal executive offices of
the Company are located at One Lakeside Commons, Suite 300, 990 Hammond Drive,
Atlanta, Georgia 30328 and its telephone number is (770) 673-1964.

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, the following risk
factors should be considered carefully in evaluating the Company and its
business before purchasing any of the shares of the Common Stock offered
hereby. This Prospectus contains forward-looking statements that involve risks
and uncertainties. Actual results could differ materially from those discussed
in the forward-looking statements as a result of certain factors, including
those set forth below and elsewhere in this Prospectus.
 
LIMITED OPERATING HISTORY; LOSSES
   
  The Company's predecessor commenced operations in 1994 and the Company
acquired its first physician practice in November 1996. To date, the Company
has not achieved profitability. For the years ended December 31, 1995 and 1996
and the nine months ended September 30, 1997, the Company incurred net losses
of approximately $531,000, $2.9 million and $16.8 million, respectively. There
can be no assurance that the Company will be able to generate sufficient
revenue to achieve profitability on a quarterly or annual basis or to sustain
or increase its revenue growth or profitability in future periods. See
"Selected Consolidated Financial Data" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."     
 
RISKS RELATED TO GROWTH STRATEGY; INTEGRATION AND MANAGEMENT OF OPERATIONS
   
  The Company intends to pursue growth primarily through the acquisition of
physician practices, growth of PHC Practices, the acquisition and development
of ancillary health care services, and the development of physician networks
and managed care contracts. As of December 31, 1997, the Company had acquired
34 physician practices, 26 of which are managed practices and eight of which
are owned practices, had interests in two businesses delivering ancillary
health care services and was providing services to 23 Affiliated Networks and
two PHC Networks. There can be no assurance that the Company will be able to:
(i) identify appropriate acquisition candidates; (ii) acquire and profitably
provide management services to additional practices; (iii) integrate such
practices successfully; (iv) develop or acquire, and operate profitably,
ancillary health care services; (v) affiliate with or develop physician
networks; and (vi) negotiate and administer additional managed care contracts.
See "Management's Discussion and Analysis of Financial Condition and Results
of Operations--Overview" and "Business--Strategy."     
   
  A significant part of the Company's growth has been and continues to be
generated by practice acquisitions. PHC's physician practice and ancillary
health care services acquisitions have all occurred since November 1996. The
Company's acquisition strategy focuses on increasing the Company's presence in
selected regional markets, thereby enhancing the Company's ability to
integrate practice management, ancillary health care services, network
development and administration, and payor contracting in its markets. Prior to
their acquisition by the Company, two practices in Orlando, Florida, Internal
Medicine Specialists, Inc. ("IMS") and Primary Care Specialists, Inc. ("PCS"),
one practice in St. Louis, Missouri, Metropolitan Plastic and Reconstructive
Surgery, Ltd. ("Metropolitan Plastic"), and an ambulatory surgery center in
Orlando, Florida were managed by persons affiliated with the Company. The
remaining practices and sleep center acquired by the Company were, at the time
of the acquisitions, managed by persons unaffiliated with the Company. The
principal benefits that PHC hopes to derive from its acquisitions are
increased revenues and profitability as well as network stability. If PHC is
to realize the anticipated benefits of its acquisitions, the operations of the
acquired practices must be efficiently integrated and, where appropriate,
combined. The process of integrating management services, administrative
organizations, facilities, management information systems and other aspects of
operations, while managing a larger and geographically expanded entity,
presents a significant management challenge. In particular, the Company must
implement an integrated financial management system that includes financial
controls and the ability to coordinate disparate financial systems. In
addition, the Company must coordinate geographically separated organizations
and integrate personnel with dissimilar business backgrounds. The dedication
of management resources to such integration efforts may detract management
attention from     
 
                                       7

acquisition and development efforts or from the day-to-day operations of the
Company. The Company first began integrating practice operations immediately
following its first practice acquisition in November 1996 and has continued to
focus on integrating practice operations as additional practices were acquired
during 1997. There can be no assurance that the integration process will be
successful, that there will not be substantial costs associated with such
activities or that such integration efforts will not have a material adverse
effect on the Company's business, financial condition or results of
operations.     
   
DEPENDENCE ON THE PHC PRACTICES AND PRACTICE MANAGEMENT AGREEMENTS     
   
  The Company's revenues are dependent on its affiliation with, and the
success of, PHC Practices and PHC Physicians, and on PHC's long-term
management contracts (the "Practice Management Agreements") with the PHC
Practices. A substantial portion of the Company's total revenues are derived
from management fees payable to the Company under the Practice Management
Agreements and patient service revenues generated by PHC Practices owned by
the Company. The management fees generally consist of combinations of the
following: (i) percentages of the earnings of the PHC Practices; (ii)
operating and non-operating expenses of the PHC Practices paid by the Company
pursuant to the Practice Management Agreements; and (iii) certain negotiated
performance and other adjustments. In Florida and Missouri the Company owns
certain PHC Practices and employs physicians under long-term employment
agreements. PHC's management fees and patient services revenue are dependent
on the productivity of the PHC Physicians. Some of the PHC Practices derive a
significant portion of their revenues from a limited number of physicians.
Although the Practice Management Agreements are generally for terms of 40
years and generally may be terminated only for cause, and the employment
agreements pursuant to which the Company directly employs physicians in states
in which it is permitted to do so (the "Direct Employment Agreements") also
may be terminated by the PHC Physicians under limited circumstances, any
termination or significant deterioration of the Company's relationship with
any of the PHC Practices or PHC Physicians could have a material adverse
effect upon the Company's business, financial condition or results of
operations. There can be no assurance that the Company or the PHC Practices
will maintain cooperative relationships with key physicians. In addition, such
physicians could retire, become disabled or otherwise become unable or
unwilling to continue generating revenues at their current level or practicing
medicine with such PHC Practice. The loss by a PHC Practice of one or more key
physicians could have a material adverse effect on the revenue of such PHC
Practice and on the Company. Additionally, although each PHC Practice and PHC
Physician is subject to a noncompete agreement, there can be no assurance that
the noncompete agreements can be enforced. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Overview" and
"Business--Contractual Agreements with PHC Practices."     
 
CONCENTRATION OF REVENUE
   
  On a pro forma basis for the year ended December 31, 1996 and for the nine-
month period ended September 30, 1997, 24% and 13%, respectively, of the
Company's net revenues were derived from Metroplex Hematology/Oncology
Associates, L.L.P. (the "Arlington Cancer Center") in Dallas/Fort Worth,
Texas, and 54% and 39%, respectively, of the Company's net revenues were
derived from a total of six PHC Practices including the Arlington Cancer
Center. In addition, most of the PHC Practices operate within a limited
geographic area, and a deterioration of economic or other conditions within
such area could have a material adverse effect on the PHC Practice and, in
turn, the Company and its business, financial condition or results of
operations.     
   
  In connection with a practice management agreement with the Arlington Cancer
Center, the Company is entitled to a management fee equal to 12% of the
practice's net revenues, plus 55% of the practice's net income after physician
compensation. Pursuant to a management services agreement with Southern
Dependacare, Inc. and its affiliates ("Southern Dependacare"), the Company is
entitled to a fee equal to the sum of: (i) 20% of the practice's income from
its Mississippi operations before physician compensation; (ii) 20% of the
practice's income from its Virginia operations before physician compensation;
and (iii) a flat fee related to its Illinois operations, which currently is
$1.6 million per year. In connection with employment agreements between 12
physicians and IMS, a practice owned by the Company, the Company is entitled
to fees during the first

five years aggregating $595,000 a year plus 15% of the income attributable to
each physician in excess of a calculated amount, and during the remainder of
each agreement a fee equal to 15% of the income attributable to each
physician. Pursuant to three management services agreements assumed by the
Company in connection with its acquisition of MidSouth Practice Management,
Inc. ("MidSouth"), a physician practice management company, the Company is
entitled to management fees equal to 12% of the income from three practices.
Pursuant to a management services agreement with P.S.A. Medical Group, Inc., a
corporation formed by the former shareholders of Parkcrest Surgical
Associates, Inc. ("Parkcrest"), the Company is entitled to a management fee
equal to a percentage of physician income attributed to each of the 14
physicians affiliated with the practice. In connection with a management
services agreement with GCGA Physicians, Inc., a corporation formed by the
former shareholders of Greater Cincinnati Gastroenterology Associates, Inc.
("Greater Cincinnati Gastro"), the Company is entitled to: (i) a management
fee equal to 20% of the practice's income before physician compensation up to
a predetermined cap; (ii) a practice development fee equal to the product of
20% of the amount by which adjusted net income exceeds a predetermined amount
multiplied by five; and (iii) a managed care development fee equal to 0.5% of
the collected revenue of the practice generated from contracts with new
managed care payors. The Company's management fee also generally includes all
direct operating expenses incurred in connection with the management of each
practice not owned by the Company.     
   
DIRECT CAPITATION AND OTHER RISKS ASSOCIATED WITH MANAGED CARE CONTRACTS     
   
  Under some managed care contracts, Affiliated Networks receive a
predetermined payment per covered member per month in exchange for providing a
potentially unlimited quantity of specified services to covered members. Such
contracts transfer much of the economic risk of providing care from the payor
to the providers, who are compensated out of a finite pool of available funds.
To the extent that covered members require more frequent or extensive care
than is anticipated, increased claims by providers for such funds may result
in reduced reimbursement to network providers. Reductions in reimbursement to
providers could adversely affect on the providers' willingness to provide
services to the Affiliated Networks or the Affiliated Networks' relationships
with contracted payors. For the nine months ending September 30, 1997, the
Company received 23% on a historical basis, and 5% on a pro forma basis, of
its revenues from the administration of managed care agreements for Affiliated
Networks. Physician dissatisfaction or defection from the Affiliated Networks,
whether due to reduced reimbursement or otherwise, or payor contract
termination could have a material adverse effect on the Company's business,
financial condition or results of operations.     
   
  In some cases, the Company enters into capitated or financial risk-sharing
managed care contracts directly with a payor. In these cases, the Company
receives the managed care payments and retains financial risk for the
provision of medical care, including responsibility for paying contracted
providers for medical services. For the nine months ending September 30, 1997,
the Company received 10% on a historical basis, and 2% on a pro forma basis,
of its total revenues from direct capitated contracts with managed care
payors. If the Company underestimates the amount of services that will be
required, it would experience reduced profitability or operating losses, which
may not be recoverable through reductions in reimbursements to providers.
Certain PHC Practices have also directly entered into capitated or financial
risk-sharing managed care contracts with payors. In the case of owned PHC
practices, the Company is directly at risk for excess utilization of medical
services. In the case of managed PHC Practices, to the extent that management
fees are calculated as a percentage of practice income, excess utilization
would result in reduced management fees.     
   
  As an increasing percentage of individuals participate in managed care
plans, the Company believes that its success will be, in part, dependent on
its ability to obtain, retain and successfully manage favorable capitated or
financial risk-sharing contracts with HMOs, employer groups, other private
third-party payors and Medicare and Medicaid. There can be no assurance that
the Company will be able to establish or maintain satisfactory relationships
with third-party payors on terms acceptable to the Company and contracted
providers. Many payors already have existing provider structures in place and
may not desire the services of the Company or the PHC Networks, and payors may
also elect to contract directly with providers on a fee-for-service, capitated
or other basis. In addition, many managed care contracts are terminable upon
short notice.

INTENSE COMPETITION     
 
  The Company, PHC Physicians, PHC Networks and Affiliated Networks face
intense competition in all aspects of their businesses. The Company believes
that changes in governmental and private reimbursement policies, among other
factors, have resulted in increased competition among providers of medical
services and among networks for payor contracts. The Company itself faces
intense competition to acquire or provide management services to physician
practices; to acquire or develop and operate ancillary health care services;
and to provide management services, including payor contracting services, to
physician networks. A number of hospitals, clinics, health care companies,
HMOs, insurance companies and physician practice management companies, both
publicly and privately held, some of which have established operating
histories and greater resources than the Company, engage in activities similar
to those of the Company. There can be no assurance that the Company will be
able to compete effectively with its competitors, that additional competitors
will not enter its markets, or that the Company will be able to acquire or
manage physician practices, acquire or develop ancillary health care services,
affiliate with or develop networks, or negotiate payor contracts on terms
beneficial to the Company. Any such failure could have a material adverse
effect on the Company's business, financial condition or results of
operations.
   
INSURANCE COVERAGE; PROFESSIONAL LIABILITY CLAIMS     
 
  All of the PHC Physicians, PHC Practices, PHC Networks, Affiliated Networks
and the Company are involved in the delivery of health care services and,
therefore, are exposed to the risk of professional or other liability claims.
Claims of this nature, if successful, could result in substantial damage
awards which may exceed the limits of any applicable insurance coverage.
Insurance against losses related to claims of this type can be expensive and
varies widely in costs and coverage. Liability claims successfully asserted
against a PHC Physician, PHC Practice, PHC Network, Affiliated Network or the
Company could have a material adverse effect on the Company's business,
financial condition or results of operations. See "Business--Corporate
Liability and Insurance."
   
NEED FOR ADDITIONAL FINANCINGS     
   
  The Company's plans to acquire and expand practices and to acquire and
develop ancillary health care services require substantial capital resources.
The Company expects that its capital needs over the next several years will
exceed capital generated from operations. In the past, the Company has funded
acquisitions of physician practices through the issuance of debt and equity
securities to sellers, the sale of equity to venture capital and other
investors and the incurrence of indebtedness. Management believes that the
Company will incur indebtedness and issue, from time to time, additional debt
or equity securities in connection with its future acquisition and development
activities, including acquisitions of physician practices, and to raise
working capital. There can be no assurance that sufficient financing will be
available on terms satisfactory to the Company. The inability to obtain
additional financing could have a material adverse effect on the Company's
business, financial condition or results of operations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."     
   
INTEGRATION OF MANAGEMENT INFORMATION SYSTEMS; RELIANCE ON THIRD-PARTY VENDOR
    
  The Company's success is dependent in part on its access to sophisticated
information systems and its ability to integrate these systems into the
existing operational, financial and clinical information systems of the PHC
Practices, PHC Networks and Affiliated Networks. Management information
systems are critical to negotiating, pricing and managing payor contracts.
These systems help PHC and the PHC Practices, PHC Networks and Affiliated
Networks realize operating efficiencies and enable them to capture, maintain,
monitor and analyze cost, quality and utilization data. In addition, PHC
Practices utilize different billing and collection systems requiring the
Company to collect manually and assimilate financial and operating data. The
Company will need to continue to invest in and administer sophisticated
management information systems to support these activities. The Company may
experience unanticipated delays, complications and expenses in implementing,
integrating and operating such systems. Furthermore, such systems may require
modifications, improvements or
 
                                      10
<PAGE>
 
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
implementation. The failure to implement successfully and maintain
operational, financial and clinical information systems could have a material
adverse effect on the Company's business, financial condition or results of
operations.
   
  PHC's current clinical information system requires software and support from
one third-party vendor to process submitted claims. Termination by such vendor
of its relationship with PHC, or a default in the performance of such vendor's
contractual obligations to PHC, could have a material adverse effect on the
Company's business, financial condition or results of operations. There can be
no assurance that such vendor's systems or support could be replaced by the
Company in a reasonable time or at a reasonable cost.     
   
RISK RELATED TO INTANGIBLE ASSETS     
   
  As a result of the Company's various acquisition transactions, the Company
has recorded approximately $63.6 million in intangible assets, net of
accumulated amortization, on a pro forma basis as of September 30, 1997.
Substantially all of such intangible assets are being amortized over 25-year
periods. The Company expects the amount allocable to intangible assets on its
balance sheet to increase in the future in connection with additional
acquisition transactions, which will increase the Company's amortization
expense. In the event of any sale or liquidation of the Company or a portion
of its assets, there can be no assurance that the value of the Company's
intangible assets will be realized. In addition, the Company regularly
evaluates whether events and circumstances have occurred indicating that any
portion of the remaining balance of amounts allocable to the Company's
intangible assets may not be recoverable. When factors indicate that the
carrying value of the Company's intangible assets may be impaired, the Company
may be required to reduce the carrying value of such assets. Any future
determination requiring the write-off of a significant portion of unamortized
intangible assets could have a material adverse effect on the Company's
business, financial condition and results of operations. See Note 1 of Notes
to Consolidated Financial Statements.     
 
GOVERNMENT REGULATION
   
  General; Federal and State Regulation     
 
  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 Company believes that health care regulations
will continue to change. The Company expects to modify its agreements and
operations from time to time as the business and regulatory environment
changes. While the Company believes it will be able to structure its
agreements and operations in accordance with applicable law, there can be no
assurance that its business or such agreements or operations will not be
successfully challenged.
 
  Every state imposes licensing requirements on individual physicians and on
facilities and services operated by physicians. In addition, federal and state
laws regulate HMOs and other managed care organizations ("MCOs") with which
the Company, PHC Physicians, PHC Practices, PHC Networks and Affiliated
Networks may have contracts. Many states require regulatory approval,
including certificates of need, before establishing or expanding certain types
of health care facilities, offering certain services or making expenditures in
excess of statutory thresholds for health care equipment, facilities or
programs. In connection with the expansion of existing operations and the
entry into new markets, the Company, PHC Physicians, PHC Practices, PHC
Networks and Affiliated Networks may become subject to compliance with
additional regulation.
 
  The United States Congress and many state legislatures routinely consider
proposals to reform or modify the health care system, including measures that
would control health care spending, convert all or a portion of government
reimbursement programs to managed care arrangements, and balance the federal
budget by reducing spending for Medicare and state health programs. These
measures can affect a health care company's cost of doing business and
contractual relationships. For example, recent developments that affect the
Company's
 
                                      11
<PAGE>
 
activities include: (i) federal legislation requiring a health plan to
continue coverage for individuals who are no longer eligible for group health
benefits and prohibiting the use of "pre-existing condition" exclusions that
limit the scope of coverage; (ii) a Health Care Financing Administration
("HCFA") policy prohibiting restrictions in Medicare HMOs or physicians
recommending to patients other health plans and treatment options; and
(iii) regulations imposing restrictions on physician incentive provisions in
physician provider agreements. There can be no assurance that such
legislation, programs and other regulatory changes will not have a material
adverse effect on the Company's business, financial condition or results of
operations.
   
  The ability of the Company to operate profitably will depend in part upon
the ability of the Company, PHC Physicians, PHC Practices, PHC Networks and
Affiliated Networks to obtain and maintain all necessary licenses,
certificates of need and other approvals and to operate in compliance with
applicable health care regulations.     
 
  Fee-Splitting; Corporate Practice of Medicine
 
  The laws of many states prohibit physicians from splitting fees with non-
physicians (or other 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. The Company's
business operations have not been the subject of judicial or regulatory
interpretation; thus, there can be no assurance that 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
existing operations or their 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.
   
  In particular, at least one Texas court has held that control by a
management company over certain medical related business aspects of a medical
practice effectively is the prohibited corporate practice of medicine by the
management company. PHC has structured the management services agreement
related to the PHC Practice managed by PHC in Texas to comply with Texas law,
although no assurance can be given that a party could not successfully assert
that such management services agreement violates Texas law. Illinois courts
have indicated that employment of physicians by for-profit corporations that
are not hospitals violates Illinois law related to the corporate practice of
medicine and that management fees based on a percentage of revenue or income
violate Illinois' prohibitions on fee-splitting. Accordingly, in Illinois PHC
does not employ physicians and the management fee charged under its Practice
Management Agreement is a flat fee. The Florida Board of Medicine recently
entered a final order in a case titled In Re: The Petition For Declaratory
Statement of Magan L. Bakarania, M.D. stating that a management fee based on a
specified percentage of net income without direct relation to the services
provided violates Florida law related to fee-splitting. That case has been
stayed pending appeal. The Company cannot predict the ultimate outcome of this
case. If the Florida Board of Medicine order is affirmed by a Florida court,
the Company will seek to restructure certain of the practice management
agreements to which it is a party in Florida, although there can be no
assurance that the Company will be successful in doing so. Three of the four
agreements that the Company may seek to restructure in Florida require the
parties to negotiate in good faith to reform the agreements to comply with
applicable law and for the matter to be referred to arbitration in the event
that agreement with respect to restructured terms cannot be reached.     
   
  Except as indicated in this Prospectus, the Company is not aware of
significant litigation related to the corporate practice of medicine or state
laws prohibiting or limiting fee-splitting that the Company anticipates will
materially affect its business. A determination in any state that the Company
is engaged in the corporate practice of medicine or any unlawful fee-splitting
arrangement could render any Practice Management Agreement between the Company
and a PHC Practice located in such state unenforceable or subject to
modification, which could have a material adverse effect on the Company's
business, financial condition and results of operations. There can be no
assurance that regulatory authorities or other parties will not assert that
the Company or a PHC Practice is engaged in the corporate practice of medicine
in such states or that the management fees paid to the Company by the
Practices constitute unlawful fee-splitting or the corporate practice     
 
                                      12
<PAGE>
 
   
of medicine. If such a claim were asserted successfully, the Company could be
subject to civil and criminal penalties and the Company or the PHC Practices
could be required to restructure their contractual arrangements. Such results
or the inability of the Company or the Practices to restructure their
relationships to comply with such prohibitions could have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Business--Government Regulation."     
 
  Changes in Payment for Medical Services
 
  The Company believes that trends in cost containment in the health care
industry will continue to result in a reduction from historical levels in per-
patient revenue for PHC Practices. The federal government has implemented,
through the Medicare program, the 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 RBRVS has reduced
payment rates for certain of the procedures historically performed by PHC
Physicians. There can be no assurance that any reduced operating margins could
be recouped by the Company through cost reductions, increased volume,
introduction of additional procedures or otherwise.
 
  Rates paid by nongovernmental insurers, including those that provide
Medicare supplemental insurance, are based on established physician,
ambulatory surgery center and hospital charges, and are generally higher than
Medicare payment rates. A change in the makeup of the patient mix of the
medical practices under Company management that results in a decrease in
patients covered by private insurance or a shift by private payors to RBRVS or
similar payment structures could adversely affect the Company's business,
financial condition or results of operations.
 
  Medicare and Medicaid Fraud and Abuse
   
  Federal law prohibits the offer, payment, solicitation or receipt of any
form of remuneration in return for, or in order to induce: (i) the referral of
a person; (ii) the furnishing or arranging for the furnishing of items or
services reimbursable under Medicare or Medicaid programs; or (iii) the
purchase, lease or order or arranging or recommending purchasing, leasing or
ordering of any item or service reimbursable under Medicare or Medicaid (the
"Anti-Kickback Law"). Pursuant to the Anti-Kickback Law, the federal
government has 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 Anti-Kickback Law can result in exclusion from Medicare and Medicaid
programs and civil and criminal penalties. The PHC Practices collectively
derived approximately 30% of their revenues on a pro forma basis for the nine
months ended September 30, 1997 from Medicare or Medicaid payments.     
   
  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 substantially
enlarging the field of physician-owned or physician-interested entities to
which the referral prohibitions apply. Stark II prohibits a physician from
referring Medicare or Medicaid patients to an entity providing "designated
health services" in which the physician has an ownership or investment
interest, or with which the physician has entered into a compensation
arrangement. The designated health services include, for example, prosthetic
devices, clinical laboratory services, radiology (such as ultrasound, MRI and
CT), home health, physical and occupational therapy, prescription drugs and
inpatient and outpatient hospital services. 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 referral violation and $100,000 for
participation in a "circumvention scheme." To the extent that the Company or
any PHC Practice is deemed to be subject to the prohibitions contained in
Stark II, the Company believes its activities fall within the permissible
activities defined in Stark II, including, but not limited to, the provision
of in-office ancillary services.     
 
                                      13
<PAGE>
 
  The Company believes that although it will receive service fees under its
agreements for management and administrative services, it is not generally in
a position to make or receive referrals of patients for services reimbursed
under the Medicare or Medicaid programs. Such service fees are intended by the
Company to be consistent with fair market value in arm's-length transactions
for the nature and amount of management services rendered and, therefore,
would not constitute unlawful remuneration under Anti-Kickback Law and
regulations. For these reasons, the Company does not believe that fees payable
to it would be viewed as remuneration for referring or influencing referrals
of patients or services covered by such programs as prohibited by statute. If
the Company is deemed to be in a position to make, influence or receive
referrals from or to physicians, the operations of the Company could be
subject to scrutiny under federal and state anti-kickback and anti-referral
laws.
 
  In certain jurisdictions that do not prohibit the corporate practice of
medicine, the Company owns practices and employs physicians. Thus, with
respect to such practices, the Company is a provider of services and would be
capable of receiving referrals from other physicians affiliated with PHC in
those markets. In these circumstances, PHC Practices either will not accept
referrals involving designated health services from other physicians
affiliated with PHC or will form group practices comprised of PHC Practices in
that market.
 
  In addition, the Company also believes that the methods used to acquire the
assets of existing practices do not violate anti-kickback and anti-referral
laws and regulations. Specifically, the Company believes the consideration
paid by the Company to physicians to acquire assets in their practices is
consistent with fair market value in arm's-length transactions and not
intended to induce the referral of patients. Should this or any other Company
practice be deemed to constitute an arrangement designed to induce the
referral of Medicare or Medicaid patients, then such 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 or results of
operations.
 
  Antitrust Issues
   
  Federal and state antitrust statutes prohibit conduct such as price fixing,
market allocation and other anti-competitive activities by groups of
competitors. The federal and state antitrust enforcement agencies have not
hesitated to bring civil and criminal enforcement actions against the joint
activities of physician organizations that violate the antitrust laws.
Collaboration regarding the pricing of services, market allocation and certain
other types of joint action, however, may be permissible in the context of an
integrated joint venture if those activities are ancillary to otherwise
legitimate purposes of the joint venture. The federal antitrust agencies, the
Federal Trade Commission and the United States Department of Justice, have
established "antitrust safety zones" for physician networks that meet certain
criteria. The antitrust safety zones are for networks in which providers share
substantial financial risk (e.g., capitation or substantial withholding) or
are engaged in designing or implementing clinical pathways with a view to
improving medical outcomes, and in which the providers constitute less than
specified percentages (20% for exclusive networks and 30% for non-exclusive
networks) of total providers in a specialty or subspecialty in the market.
Conduct outside the safety zones is not necessarily unlawful, but antitrust
regulatory authorities will give greater scrutiny to the potential impact on
overall competition. State antitrust agencies may or may not rely on antitrust
analysis similar to that of the federal agencies.     
   
  The two PHC Networks are non-exclusive networks that operate in the greater
Atlanta and greater Orlando metropolitan areas, respectively. Except for one
fee-for-service contract in Orlando, all of their contracts are capitated or
global risk contracts in which the providers share substantial financial risk.
The Atlanta PHC Network is comprised of primary care physicians constituting
less than 30% of the market practitioners of family/general, internal and
pediatric medicine. The Company believes that the Atlanta PHC Network is
within the antitrust safety zone for non-exclusive networks. The Orlando PHC
Network is a multi-specialty network including physicians of many specialties.
The Company believes that physician representation in the Orlando PHC Network
may exceed the non-exclusive safety zone in several non-primary care
specialties. The antitrust agencies emphasize, however, that even if a
physician network does not come within a safety zone, it is not necessarily
unlawful under the antitrust laws. For the following reasons, the Company
believes that its activities     
 
                                      14
<PAGE>
 
   
in the greater Orlando metropolitan area are pro-competitive and have the
potential to benefit purchasers of the physician services offered by its
providers. First, physician participation in the network is non-exclusive, and
physician members do in fact contract with other networks and health plans.
Second, physician members share inherent substantial financial risk by
providing services for global risk contracts and have the incentive to provide
high quality, cost-effective care in an environment of increasing managed care
penetration. Third, there are competing physician networks in the greater
Orlando area. Fourth, the specialties in which the Orlando PHC Network may
exceed the safety zone are generally ones characterized by a limited number of
practices and physicians within the market.     
 
  Insurance Regulatory Risks
   
  An important element of the Company's business and strategy includes acting
as an agent for PHC Physicians, PHC Networks and Affiliated Networks to
negotiate with insurance companies, HMOs, employer self-funded plans, health
plans and other MCOs for the provision of health care services to the
subscribers or beneficiaries of the health plans operated by such parties.
Under some of these contracts, the Company receives capitated payments on
behalf of a network and reimburses participating physicians on a fee-for-
service basis. Under the laws of some states, this contracting arrangement
could be determined to involve an insurance risk. Therefore, to the extent the
Company is deemed to be in the business of insurance in a particular state,
the Company, PHC Physicians and PHC Networks could be subject to insurance
regulatory scrutiny; regulators could require restructuring of a specific
arrangement; and the Company's operations could be restricted, its expansion
limited, or certain of its operations prohibited.     
   
  Medicare Developments     
   
  The recently adopted Balanced Budget Act of 1997 ("BBA") enacted a Medicare
Plus/Medicare Choice Program for Medicare enrollees. The program would broaden
the coverage options available to Medicare recipients, would authorize broader
use of medical savings accounts, and would allow physicians and patients to
contract for health care services at rates beyond what is paid by Medicare.
Such changes potentially could increase the services utilized by Medicare
recipients. In addition, the BBA allows provider-sponsored organizations
("PSOs") to contract directly with Medicare, instead of contracting through an
HMO. If the PHC Practices, PHC Networks and Affiliated Networks participate in
such PSOs, they could increase the percentage of Medicare-related business,
which would also increase the exposure for losses if Medicare revenues fall
short of the cost of services actually utilized by Medicare beneficiaries. If
PHC does not participate in such PSOs, whether by choice or because it does
not obtain a required license to act as a PSO, PHC's ability to participate in
Medicare programs could be limited. The BBA also amends the fraud and abuse
laws to require permanent exclusion from Medicare of anyone convicted of three
Medicare program-related crimes and to impose new civil monetary penalties to
anyone contracting with an excluded health care provider. These changes
increase the regulatory and other risks encountered by the Company. See "--
Direct Capitation and Other Risks Associated With Managed Care Contracts."
       
 Legislative Developments     
 
  In addition, proposed legislation regarding health care reform has been
introduced before many state legislatures. Any such reform at the federal or
state level could significantly alter patient-provider relationships. State
and federal agency rule-making addressing these issues is also expected. No
predictions can be made as to whether future health care reform legislation,
similar legislation or rule-making will be enacted or, if enacted, its effect
on the Company. Any federal or state legislation prohibiting investment
interests in, or contracting with, the Company by health care providers for
which there is no statutory exception would have a material adverse effect on
the Company's business, financial condition or results of operations.
 
DEPENDENCE ON KEY PERSONNEL
   
  The development of the Company's business and its operations have been
materially dependent upon the active participation of the Company's executive
officers and key employees. The loss of the services of one or more of these
persons could have a material adverse effect on the business, financial
condition or results of operations of the Company. The Company maintains a key
person life insurance policy in the amount of $3.0 million on the life of its
Chief Executive Officer and President, Sarah C. Garvin. See "Management."     
 
                                      15

CONTROL BY EXISTING STOCKHOLDERS
   
  Upon completion of this Offering, the officers and directors of the Company,
together with their affiliates, will own beneficially approximately 22.9% of
the outstanding shares of Common Stock (22.0% if the Underwriters' over-
allotment option is exercised in full). Such persons acting together could
have a significant influence on matters requiring stockholder approval,
including the election of directors, mergers and other extraordinary corporate
events. See "Management" and "Principal Stockholders."     
 
SHARES ELIGIBLE FOR FUTURE SALE
   
  The market price of the Common Stock of the Company could be adversely
affected by the sale of substantial amounts of the Common Stock in the public
market following the Offering. The shares being sold in the Offering will be
freely tradable unless acquired by affiliates of the Company. Certain
stockholders of the Company hold, in the aggregate, 7,093,240 shares of Common
Stock and 288,193 shares of Non-Voting Common Stock, none of which were
acquired in transactions registered under the Securities Act. Accordingly,
such shares may not be sold except in transactions registered under the
Securities Act or pursuant to an exemption from registration. The Company and
its directors, executive officers and current stockholders holding an
aggregate of            shares have agreed not to offer or sell any shares of
Common Stock for a period of 180 days (the "180-Day Lockup Period") following
the date of this Prospectus without the prior written consent of BancAmerica
Robertson Stephens, except that the Company may, subject to certain
conditions, issue Common Stock in connection with acquisitions and with awards
under the 1995 Stock Option Plan. After the expiration of the 180-Day Lockup
Period, such shares may be sold in accordance with Rule 144 under the
Securities Act, subject to the applicable volume limitations, holding period
and other requirements of Rule 144.     
   
  The Company intends to register an additional 1,500,000 shares of its Common
Stock under the Securities Act subsequent to completion of the Offering for
use by the Company as all or a portion of the consideration to be paid in
future acquisitions. Those shares, if issued, will be freely tradable by
nonaffiliates after their issuance, unless the resale thereof is contractually
restricted, and resales of any such shares during the 180-Day Lockup Period
would require the prior written consent of BancAmerica Robertson Stephens.
       
  The Company anticipates that, prior to the consummation of the Offering, the
Company will have outstanding under the 1995 Stock Option Plan options to
purchase approximately 1,623,442 shares of Common Stock. The Company intends
to register the shares issuable upon exercise of options granted under the
1995 Stock Option Plan. See "Management--1995 Stock Option Plan" and "Shares
Eligible for Future Sale."     
 
NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
  Prior to the Offering, there has been no public market for the Common Stock,
and there can be no assurance that an active trading market will develop or,
if a trading market does develop, that it will continue after the Offering.
The initial public offering price of the Common Stock will be determined
through negotiations between the Company and the Underwriters and may not be
indicative of the price at which the Common Stock will trade after the
Offering. See "Underwriting" for a description of the factors to be considered
in determining the initial public offering price. The securities markets have,
from time to time, experienced significant price and volume fluctuations that
may be unrelated to the operating performance of particular companies. These
fluctuations often substantially affect the market price of a company's stock.
The market prices for securities of health care practice management companies
have been and continue to be particularly volatile. The market price of the
Common Stock could be subject to significant fluctuations in response to
numerous factors, including variations in financial results or announcements
of material events by the Company or its competitors. Regulatory changes,
developments in the health care industry or changes in general conditions in
the economy or the financial markets could also adversely affect the market
price of the Common Stock.
   
POTENTIAL ANTI-TAKEOVER EFFECTS OF CHARTER AND BYLAW PROVISIONS; POSSIBLE
ISSUANCES OF PREFERRED STOCK     
 
  Certain provisions of the Company's Certificate of Incorporation and Bylaws
and Delaware law could, together or separately, discourage potential
acquisition proposals, delay or prevent a change in control of the
 
                                      16
<PAGE>
 
Company or limit the price that certain investors may be willing to pay in the
future for shares of the Common Stock. The Certificate of Incorporation also
permits the Board of Directors to determine the rights, preferences and
restrictions of unissued series of the Company's authorized Preferred Stock
and to fix the number of shares and the designation of and to nominate
directors, to submit proposals to be considered at stockholders' meetings and
to adopt amendments to the Bylaws. Such provisions of the Certificate of
Incorporation and Bylaws: (i) divide the Company's Board of Directors into
three classes, each of which will serve for different three-year periods and
(ii) restrict the right of stockholders to call a special meeting of
stockholders. The Company also is subject to Section 203 of the Delaware
General Corporation Law ("DGCL"), which, subject to certain exceptions,
prohibits a Delaware corporation from engaging in any of a broad range of
business acquisitions with an "interested stockholder" for a period of three
years following the date such stockholder became an interested stockholder.
See "Description of Capital Stock."
 
RISKS ASSOCIATED WITH UNSPECIFIED USE OF PROCEEDS
 
  A significant portion of the net proceeds of the Offering will be available
for working capital and general corporate purposes, including the acquisition
of physician practices, the acquisition and development of ancillary health
care services and development of physician networks and payor contracts. The
Company's management, subject to approval by the Board of Directors, will have
broad discretion with respect to the use of such proceeds of the Offering. See
"Use of Proceeds."
 
IMMEDIATE AND SUBSTANTIAL DILUTION
   
  Purchasers of shares of Common Stock offered hereby will experience
immediate and substantial dilution in the pro forma net tangible book value of
their shares in the amount of $12.55 per share. In the event the Company
issues additional Common Stock in the future, including shares that may be
issued in connection with future acquisitions, purchasers of Common Stock in
the Offering may experience further dilution in the net tangible book value
per share of Common Stock. See "Dilution."     
 
ABSENCE OF DIVIDENDS
 
  The Company has never paid any cash dividends and does not anticipate paying
cash dividends on its Common Stock in the foreseeable future. See "Dividend
Policy."
 
                                      17
<PAGE>
 
                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby (after deducting the underwriting discounts and commissions and
estimated Offering expenses) are estimated to be approximately $39.3 million
(approximately $45.6 million if the Underwriters' over-allotment option is
exercised in full), assuming an initial public offering price of $15.00 per
share (the midpoint of the estimated initial public offering price range). Of
such net proceeds: (i) approximately $21.0 million will be used to repay
certain of the Company's indebtedness immediately following the Offering; (ii)
$6.2 million will be used to repay certain indebtedness of the Company in
April 1998; (iii) $300,000 will be used to pay accrued but unpaid dividends on
the Class A Stock; and (iv) the remainder will be available for working
capital and general corporate purposes, including the acquisition of physician
practices, the acquisition and development of ancillary health care services
and the development of physician networks and payor contracts. The Company has
no present agreements for the acquisition of physician practices or ancillary
health care services. Pending such uses, the net proceeds will be invested in
short-term, interest bearing, investment grade securities. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."     
   
  The indebtedness to be retired with the proceeds of the Offering is
comprised of approximately $12.0 million outstanding under the Company's
senior credit facility (the "Senior Debt") and approximately $9.0 million in
senior subordinated debt (the "Subordinated Debt"). The Company is required to
retire the Subordinated Debt with the proceeds of this Offering. The Company
is required to use net proceeds to the Company from this Offering in excess of
$40 million to retire the Senior Debt. The Senior Debt was incurred in
November and December 1997 to finance acquisitions, pay transaction expenses
and for general corporate purposes, bears interest at a floating rate equal
to, at the Company's option, prime plus 1.75% or LIBOR (the London InterBank
Offered Rate) plus 3.0%, and is payable in quarterly installments until
maturity in April 2002.     
   
  The Subordinated Debt bears interest at the rate of 12.0% per annum and is
payable in full in November 2004. The proceeds of the Subordinated Debt, which
were obtained by the Company in November 1997, were used by the Company to
refinance certain prior acquisitions, finance acquisitions and pay transaction
costs. In April 1998, the Company also will use the proceeds of the Offering
to retire a $6.2 million unsecured non-interest bearing note that matures at
that time and constituted a portion of the consideration paid in the
acquisition of the Arlington Cancer Center. The proceeds of the Senior Debt
and Subordinated Debt were used to finance the acquisitions of Louisville
Cardiology Medical Group, PSC, Physicians Strategic Alliance, Inc., Southern
Dependacare, Healthcare Strategic Initiatives LLP, Pulmonary Sleep
Consultants, Inc., Diagnostic Internists, Inc., Parkcrest Surgical Associates,
Inc., IMS, Primary Care Specialists, Inc., Larach, Williamson & Ferrara, Inc.,
National Sleep Dynamics, Inc., Home Care for Sleep Disorders, Inc., Greater
Cincinatti Gastro, Northside Ob-Gyn, P.C. and Eagles Landing Ob-Gyn
Associates, P.C.     
 
                                DIVIDEND POLICY
 
  It is the Company's current intention to retain earnings for the foreseeable
future to support operations and finance expansion. The payment of any future
dividends will be at the discretion of the Company's Board of Directors and
will depend upon, among other things, the Company's earnings, financial
condition, cash flow from operations, capital requirements, expansion plans,
the income tax laws then in effect, the requirements of Delaware law and
restrictions that may be imposed in the Company's future financing
arrangements. In addition, the Company's senior credit facility prohibits the
payment of dividends.

  The following table sets forth the short-term debt and the capitalization of
the Company: (i) at September 30, 1997; (ii) on a pro forma basis to reflect
the acquisitions of PHC Practices since September 30, 1997 and the conversion
of the Company's Prime Common Stock, Class A Stock (Series 1 and Series 2),
Series B Redeemable Convertible Preferred Stock (the "Series B Voting
Preferred Stock") and Series B Non-Voting Redeemable Convertible Preferred
Stock (the "Series B Non-Voting Preferred Stock"); and (iii) on a pro forma
basis as adjusted to give effect to the receipt and application of the net
proceeds of the Offering. See "Use of Proceeds." The Series B Voting Preferred
Stock and the Series B Non-Voting Preferred Stock are collectively referred to
as the "Series B Preferred Stock." This table should be read in conjunction
with "Unaudited Pro Forma Combined Financial Statements," "Management's

                                   DILUTION
   
  The net tangible book value (deficit) of the Company as of September 30,
1997 was approximately $(29.0) million, or approximately $(10.82) per share.
The pro forma net tangible book value of the Company as of September 30, 1997
was approximately $(13.8) million, or approximately $(1.88) per share. Pro
forma net tangible book value (deficit) per share is determined by dividing
the net tangible book value of the Company (tangible assets less total
liabilities) by the number of shares of Common Stock outstanding, giving pro
forma effect to the conversion of all outstanding shares of Prime Common
Stock, Class A Stock, Series B Preferred Stock into 3,685,889 shares of Common
Stock and 288,193 shares of Non-Voting Common Stock. After giving effect to
the sale by the Company of 3,000,000 shares of Common Stock offered at a price
of $15.00 per share (the midpoint of the estimated initial public offering
price range) and the application of the estimated net proceeds therefrom as
set forth under "Use of Proceeds," the pro forma net tangible book value of
the Company as of September 30, 1997 would have been $2.45 per share. This
represents an immediate increase in the net tangible book value of
approximately $39.3 million, or approximately $4.33 per share to existing
stockholders and an immediate dilution to new investors purchasing Common
Stock in the Offering of approximately $12.55 per share. The following table
illustrates the per share dilution to new investors purchasing Common Stock in
the Offering:

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
   
  The following unaudited pro forma combined financial statements include the
unaudited pro forma combined balance sheet of the Company as of September 30,
1997, and the unaudited pro forma combined statements of operations for the
year ended December 31, 1996 and nine months ended September 30, 1997.     
   
  The accompanying unaudited pro forma financial statements give effect to the
following pro forma adjustments (collectively, the "Transactions"): (i) the
asset acquisitions of the PHC Practices at fair market value and related
purchase accounting adjustments; (ii) the entering into of a $62.5 million
credit agreement with a syndicate of banks led by Banque Paribas; (iii) the
entering into of a $15.0 million subordinated credit agreement with an
affiliate of Banque Paribas; (iv) the issuance of equity securities to an
affiliate of Banque Paribas; and (v) the consummation of the Offering.     
   
  The asset acquisitions of physician practices have been accounted for under
the purchase method of accounting, and pro forma adjustments include: (i) the
elimination of patient service revenue for all practices in which the Company
does not have an equity ownership interest; (ii) the addition of management
fee revenue for practices in which the Company does not have an equity
ownership interest; (iii) the payment of cash and the issuance of Common Stock
and notes to the former practice owners; and (iv) the allocation of purchase
price in excess of net assets to intangibles.     
   
  The accompanying unaudited pro forma combined balance sheet gives effect to
the Transactions occurring after September 30, 1997 as if they had occurred on
September 30, 1997. The accompanying unaudited pro forma combined statements
of operations give effect to the Transactions as if they had occurred on
January 1, 1996.     
   
  The Company has performed a preliminary analysis of the savings that it
expects to realize as a result of: (i) consolidating certain general and
administrative functions; (ii) the reduction in interest payments related to
the repayment of certain outstanding acquisition debt; (iii) its ability to
borrow at lower interest rates than the individual practices; (iv) the
interest earned on the net proceeds of the Offering remaining after
applications of proceeds as described in "Use of Proceeds;" and (v)
efficiencies in other general and administrative areas. The Company has not
and cannot quantify these savings until after completion of the Offering and
acquisitions. It is anticipated that these savings will be partially offset by
the costs of the Company's recent additions to senior management and expenses
associated with being a public company. These costs cannot be quantified
accurately. Accordingly, only those anticipated savings and costs that are
factually supportable have been included in the accompanying pro forma
financial information of the Company.     
   
  The unaudited pro forma combined financial statements are not necessarily
indicative of the Company's financial condition or results of operations that
would have been achieved if the Transactions had occurred as of September 30,
1997 or January 1, 1996 or of future operations. See "Risk Factors."     
   
  The unaudited pro forma combined financial statements should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the historical financial statements and notes
of the Company; Arlington Cancer Center; Greater Cincinnati Gastro; IMS;
Parkcrest; and Southern Dependacare, which are included elsewhere in this
Prospectus.

          NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
1. BACKGROUND
   
  Physician Health Corporation is a physician management company focusing on
the value-added integration of practice management, ancillary health care
services, network development and administration, and payor contracting in
selected markets. As of December 31, 1997, the Company provided payor contract
administration and related services to 25 physician networks, one of which is
owned by the Company, one of which is a nonprofit corporation of which the
Company is the sole member (together, the "PHC Networks") and the remainder of
which are independent entities that receive services from the Company (the
"Affiliated Networks"). The PHC Networks and Affiliated Networks included
approximately 3,300 physicians and 2.3 million covered lives under 29 managed
care contracts including specialty capitated and global risk contracts. As of
December 31, 1997, the Company provided practice management services to 34
physician practices ("PHC Practices") including 171 physicians (the "PHC
Physicians"). The Company was a party to Practice Management Agreements with
26 of the PHC Practices that employed 113 PHC Physicians. The Company directly
owned and operated the remaining eight PHC Physicians through which it
directly employed 58 PHC Physicians.     
   
  There are three types of economic models that the Company has under its
management services agreement: (i) a designated percentage of net patient
service revenue, ranging from 10% to 25%; (ii) a designated percentage of net
patient service revenue, with potential adjustments based on income before
physician compensation above certain negotiated levels; and (iii) a guaranteed
dollar fee. See "Management's Discussion and Analysis of Financial Condition
and Results of Operation--Overview."     
 
2. HISTORICAL FINANCIAL STATEMENTS
   
  The historical financial statements represent the financial position and
results of operations of the Company and physician practices and were derived
from the respective financial statements where indicated. All entities
acquired in the asset acquisitions have a December 31 year end, except for
Parkcrest whose fiscal year end is March 31. Since Parkcrest's year end is
within 93 days of December 31, its results have not been recast. The audited
historical financial statements included elsewhere in this Prospectus have
been included in accordance with applicable Securities and Exchange Commission
rules and regulations. The Company will continue to have a December 31 year
end.     
   
  Arlington Cancer Center and Southern Dependacare were acquired by Physician
Health Corporation as of June 1, 1997 and September 1, 1997, respectively.
Their operating results after their respective acquisition dates are included
in the results of operations of Physician Health Corporation for the nine
months ended September 30, 1997.     
 
3. PHYSICIAN PRACTICE ASSET ACQUISITIONS
 
  The Company has acquired substantially all of the net assets of the
physician practices. See "Business-- Operations." These asset acquisitions
will be accounted for using the purchase method of accounting.
   
  The Company had acquired 12 physician practices through asset acquisitions
as of September 30, 1997. See Note 2 to the Notes to the Consolidated
Financial Statements of the Company.

  The holders of most shares of PHC stock issued as consideration in the asset
acquisitions since mid-October 1997 have contractually agreed with the Company
not to offer, sell, or otherwise dispose of any of those shares for a holding
period ranging from 14 months to 42 months after the respective asset
acquisitions. The fair value of these shares reflects this restriction.
   
  The estimated total purchase price (based on the fair value of the shares to
be issued) of the asset acquisitions since September 30, 1997 is allocated as
follows (in thousands):     
 
<TABLE>

  Based on management's preliminary analysis, it is anticipated that the
historical carrying value of the acquisitions' assets and liabilities will
approximate fair value. Management of the Company has not identified any other
material tangible or identifiable intangible assets of the acquisitions to
which a portion of the purchase price could reasonably be allocated. This
preliminary allocation is not expected to differ materially from the final
allocation.     
 
  The following is a summary of the adjustments reflected in the Unaudited Pro
Forma Financial Statements giving effect to the completion of the asset
acquisitions of the PHC Practices. The Company has not acquired equity
interests in most of the PHC Practices, but has acquired substantially all of
the non-medical assets of the Practices and, in most cases, will have a 40-
year Practice Management Agreement with each practice.

  (a) Reflects the adjusted net assets acquired, at fair-market value, from
      the asset acquisitions since September 30, 1997. See Note 3.     
     
  (b) Reflects the adjusted intangible amount associated with the asset
      acquisitions since September 30, 1997. The ending intangibles amount of
      $63.6 million as of September 30, 1997 also includes estimated
      capitalized costs associated with the asset acquisitions of $1.2
      million.

    NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  (e) Reflects the elimination of patient service revenue for all physician
      practices with which the Company has a Practice Management Agreement,
      but will not directly employ the physicians of such practices. See (h).
 
  (f) Reflects the management service revenue received from the Practice
      Management Agreements. Pursuant to Practice Management Agreements, the
      Company will act as the exclusive manager and administrator of a PHC
      Practice. The Practice Management Agreements provide for the PHC
      Practice to assign to the Company all or substantially all of its
      rights and interests in the proceeds of its non-governmental accounts
      receivable (or the revenue it receives) and grants to the Company the
      right to collect and retain the proceeds of governmental accounts
      receivable (or revenue) for the Company's account to be applied in
      accordance with the agreement. Although such proceeds of the accounts
      receivable (or revenue) are collected by the Company on behalf of the
      practice, the practice grants to the Company the right to grant a
      security interest and factor such accounts, and such receivables secure
      Company borrowings under its credit facility.
 
  (g) Reflects the elimination of physician compensation at the practices in
      which the Company does not have an equity ownership interest. After the
      Company collects its management fees pursuant to the Practice
      Management Agreements, the remaining revenues will be remitted to the
      PHC Practice to pay physician compensation and benefits pursuant to
      employment agreements between the practice and each individual
      physician and to pay physician assistant compensation and benefits.
 
  (h) Reflects the cost of salaries of the physicians employed by the Company
      after the asset acquisition of the various practices.
     
  (i) Intentionally not used.     
     
  (j) Reflects the adjusted depreciation of the property and equipment
      acquired and amortization of the intangibles associated with the asset
      acquisitions. Substantially all of the intangibles are being amortized
      over 25-year periods. See Note 3.     
 
  (k) Reflects the reversal of one-time write offs recorded by the Company in
      connection with the purchase of research and development acquired in
      the Arlington Cancer Center acquisition. See the Consolidated Financial
      Statements of the Company and the Notes thereto.
 
  (l) Reflects interest expense on asset acquisition indebtedness based on
      the interest rate applicable to each instrument.
 
  (m) Includes the elimination of the minority interest portion of one-time
      write offs at the Arlington Cancer Center. See (k). Also includes the
      minority interest in the net income of Arlington Cancer Center and
      Jones Eyecare Center.
 
  (n) Reflects the establishment of a provision for income taxes. Most of the
      practices are S corporations with such corporations owing no federal or
      state taxes and the shareholders of each such entity being responsible
      for their payment.

  (p) Certain stock options have been granted by the Company. Stock options
      granted at fair market value to employees are accounted for under APB
      No. 25 and do not require compensation cost to be recognized. Stock
      options granted below fair market value to employees do require
      compensation costs to be recognized. Stock options granted to
      nonemployees are accounted for under SFAS No. 123. This accounting
      standard requires options to be recorded at fair value, which normally
      entails compensation expense.     
   
  The Company has entered into an agreement with Banque Paribas for a $20.0
million term loan facility, a $32.5 million acquisition line facility, a $10.0
million working capital revolving loan facility, and an approximately $15.0
million subordinated debt loan facility. All the facilities will bear interest
at a floating rate of prime plus 1.75% or, at the Company's option, LIBOR plus
3.0%, with the exception of the subordinated debt which bears interest at
12.0%. Additionally, an affiliate of Banque Paribas purchased approximately
553,683 shares of Series B Voting Preferred Stock of the Company for
approximately $2.2 million. In connection with this investment and the
subordinated debt, the Company issued Banque Paribas affiliates warrants
exercisable for 376,800 shares of Non-Voting Common Stock and 58,090 shares of
Common Stock. If the Company completes an initial public offering by February
28, 1998 or April 27, 1998, respectively, the Banque Paribas affiliates will
forfeit warrants exercisable for 226,080 or 188,400 shares of Non-Voting
Common Stock, respectively, retaining warrants exercisable for 150,720 or
188,400 shares of Non-Voting Common Stock, respectively as well as retaining
the warrants exercisable for 58,090 shares of Common Stock.     
   
  The Company used $12.0 million of the $20.0 million term loan and $9.0
million of the subordinated debt to pay or refinance the cash component of the
acquisitions consummated since September 30, 1997 and to pay transaction
costs. See Note 3. The remaining $8 million under the term loan and $6 million
under the subordinated loan is available only to pay certain other outstanding
indebtedness of the Company. Approximately $2.1 million of the acquisition
line facility has been drawn to pay the cash component of acquisition
consummated following September 30, 1997, and the remaining $30.4 million is
available for future acquisitions. The $2.2 million equity infusion has been
will be used for general corporate purposes, including working capital.

Company. The selected consolidated financial data for the period from
inception to December 31, 1995, the year ended December 31, 1996 and the nine
month period ended September 30, 1997 are derived from the audited
consolidated financial statements of the Company, and the selected
consolidated financial data for the year ended December 31, 1994 and for the
period from January 1, 1995 to October 31, 1995 are derived from the audited
financial statements of the Predecessor. The selected consolidated financial
data for the nine month period ended September 30, 1996 are derived from the
unaudited financial statements of the Company. As a result of acquisitions
occurring in 1997, the Company's historical financial statements are not

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion and analysis contains certain forward-looking
statements 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. As a result of the substantial
number of recent acquisitions, 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 Unaudited Pro
Forma Combined Financial Statements and the Financial Statements and related
Notes thereto included elsewhere in this Prospectus.
 
OVERVIEW
   
  Physician Health Corporation is a physician management company focusing on
the value-added integration of practice management, ancillary health care
services, network development and administration, and payor contracting in
selected markets. As of December 31, 1997, the Company provided payor contract
administration and related services to 23 Affiliated Networks and two PHC
Networks. The PHC Networks and Affiliated Networks included approximately
3,300 physicians and had approximately 2.3 million covered lives under 29
managed care contracts including specialty capitated and global risk
contracts. As of December 31, 1997, the Company also provided practice
management services to 34 PHC Practices including 171 PHC Physicians. The
Company was a party to Practice Management Agreements with 26 of the PHC
Practices that employed 113 PHC Physicians through practice management
agreements. The Company directly owned and operated the remaining eight PHC
Practices through which directly employed 58 PHC Physicians.     
   
  The Company commenced operations in 1994 as a wholly-owned subsidiary of
Surgical Health Corporation. PHC was incorporated in Delaware in August 1995
and acquired the Predecessor in November 1995. The Company's current regional
markets are centered in Atlanta, Georgia; Cincinnati, Ohio; Dallas/Ft. Worth,
Texas; Memphis, Tennessee; Orlando, Florida; and St. Louis, Missouri. The
Company also provides services in Alabama, Arizona, Illinois, Kentucky,
Mississippi and Virginia.     
   
  The Company derives its revenues from five primary sources: (i) management
fees from management of PHC Practices; (ii) patient service revenues generated
by PHC Practices owned by the Company; (iii) reimbursements of operating
expenses paid by PHC on behalf of the managed PHC Practices; (iv) management
fees from management of Affiliated Networks and administering managed care
contracts; and (v) revenues from the operation of ancillary health care
services. The practice management fees payable to PHC by the PHC Practices
vary based on the nature and amount of services provided. The practice
management fees are payable monthly and generally consist of percentages of
revenues or the income of the PHC Practices. For the nine months ended
September 30, 1997 revenues from the Company's practice management business,
ancillary health care services business and contracting business constituted
approximately 77%, 0%, and 23% of the Company's total revenues, respectively.
On a pro forma basis for the nine months ended September 30, 1997, revenues
from the Company's practice management business, ancillary health care
services business and contracting business constituted approximately 93%, 2%,
and 5% of the Company's total revenues, respectively.     
   
  Management fees payable to the Company under the Practice Management
Agreements are determined in arm's-length negotiations based on the nature and
amount of services provided. Such fees generally consist of combinations of
the following: (i) percentages (generally ranging from 10% to 25%) of the
earnings of the PHC Practices; (ii) operating and non-operating expenses of
the PHC Practices paid by the Company pursuant to the Practice Management
Agreements; and (iii) certain negotiated performance and other adjustments. In
negotiating performance and other adjustments, the principal factor considered
by the Company and the PHC Practice is the potential for growth in the revenue
or profitability of the PHC Practice and whether adjustments to the base fee
are appropriate as any such growth occurs. In the case of the Arlington Cancer
Center, the Company's     
 
                                      31
<PAGE>
 
   
management fee is 12% of revenues plus 55% of the practice's income after
physician compensation. In Illinois where fees based on percentages of
revenues or income are not permissible, PHC charges a flat fee. In many
instances, for the first five years of the term of a Practice Management
Agreement the service fee is the greater of the fee determined by the
applicable formula or a fixed minimum amount. The base minimum amounts
typically are determined by multiplying the percentage of earnings that has
been agreed upon as the base management fee by the historical earnings of the
PHC Practice for a recent period. Payment of this minimum is, in many
instances, guaranteed by the physicians and the practice. For a description of
the terms of the Practice Management Agreements and Direct Employment
Agreements, see "Business--Contractual Agreements with PHC Practices."     
       
       
       
       
          
  Operating expenses include the expenses incurred by the Company in
fulfilling its obligations under the Practice Management Agreements. These
expenses are the same as the operating costs and expenses that would have been
incurred by the PHC Practices, including salaries, employee benefits, medical
supplies, building rent, equipment leases, malpractice insurance premiums,
management information systems, and other expenses related to practice
operations. In addition to the practice expenses discussed above, the Company
also incurs personnel and administrative expenses in connection with
maintaining a corporate office that provides management, administrative,
marketing and acquisition services to the PHC Practices, organizes networks
and negotiates and administers payor contracts, and manages and develops
ancillary health care services. The Company can only indirectly manage the
profitability of the PHC Practices the Company does not own. To the extent
that a PHC Practice, with the assistance of the Company pursuant to the
Practice Management Agreement, increases its revenues or decreases its
operating expenses, the practice management fee payable to the Company may
increase.     
       
          
  The Company earns management fees from management of networks and managed
care contracts under agreements between the Company and the PHC Networks or
Affiliated Networks. These agreements generally provide that the Company is
entitled to receive a percentage of the payments made by payors to the
network, ranging from 4.5% to 10.0%. The agreements with the networks
generally have terms of from one to five years, with provisions for automatic
renewal at the end of the term. See "Business--Operations."     
   
  In some cases, the Company enters into capitated or financial risk-sharing
managed care contracts directly with the payors. In these cases, the Company
receives the managed care payments and retains financial risk for care,
including responsibility for paying contracted providers for medical services.
To the extent that the cost of services falls below expectations, the Company
retains a larger portion of the managed dollar. Excess services, on the other
hand, would result in reduced profitability or operating losses to the
Company. See "Business--Operations."     
   
  The structure of the financial interest held by the Company in ancillary
health care services delivered by the Company or the PHC Practices will differ
based on the Company's evaluation of the requirements of state laws
prohibiting the corporate practice of medicine, as well as federal and state
anti-kickback and self-referral laws. Where legally permissible, the Company
may own all or part of an ancillary health care service provider. In other
instances the Company may manage the delivery of ancillary health care
services through a PHC Practice in exchange for a management fee. Currently,
the Company has an interest in a wholly-owned sleep laboratory located in
Atlanta, Georgia and a 51% partnership interest in an ambulatory surgery
center located in Orlando, Florida. The Company derives revenue from the sleep
laboratories through the conduct of sleep studies and the sale of durable
medical equipment related to sleep disorders. Revenues from the ambulatory
surgery center are derived from facility fees charged by the center. The
Company also manages this ambulatory surgery center for a fee of 6% of the
center's revenues. The Company has options, commencing in June 1998, to
purchase a 51% interest in two other ambulatory surgery centers located in
Orlando, Florida.

  Since November 1996, the Company has acquired 34 PHC Practices that are
affiliated with 171 PHC Physicians. Aggregate consideration paid in connection
with these acquisitions was approximately $88.5 million, consisting of
approximately $29.2 million in cash, approximately $14.8 million in promissory
notes, approximately $44.6 million in Company stock and 20% interests in three
Company subsidiaries that are convertible into a total of approximately
693,000 shares of Common Stock. In connection with these acquisitions, PHC has
recognized or will recognize approximately $63.6 million in intangibles.     
   
  On June 16, 1997, the Company acquired substantially all of the assets of
the Arlington Cancer Center for approximately $11.8 million in cash, $12.6
million in promissory notes and a 20% membership interest in MHOA Texas I,
LLC, the subsidiary of the Company that purchased such assets and manages the
Arlington Cancer Center. On September 12, 1997, the Company acquired
substantially all of the assets of Southern Dependacare for approximately $4.5
million in cash, $1.8 million in promissory notes and 540,000 shares of Prime
Common Stock. On November 10, 1997, pursuant to an Agreement and Plan of
Merger, a wholly-owned subsidiary of the Company was merged with and into
Greater Cincinnati Gastro, all of the shares of capital stock of Greater
Cincinnati Gastro were converted into the right to receive, in the aggregate,
approximately $3.5 million in cash and approximately 410,000 shares of Common
Stock, and Greater Cincinnati Gastro became a wholly-owned subsidiary of the
Company. On November 12, 1997 pursuant to an Agreement and Plan of Merger,
Parkcrest was merged with and into a wholly-owned subsidiary of the Company,
all of the outstanding shares of capital stock of Parkcrest were converted
into the right to receive, in the aggregate, $348,148 in cash and
approximately 406,400 shares of Common Stock, and Parkcrest became a wholly-
owned subsidiary of the Company. On November 12, 1997, pursuant to an
Agreement and Plan of Merger, a wholly-owned subsidiary of the Company was
merged with and into IMS, all of the outstanding capital stock of IMS
converted into the right to receive, in the aggregate, approximately $3.7
million in cash and 351,867 shares of Common Stock, and IMS became a wholly-
owned subsidiary of the Company. On November 12, 1997, pursuant to an
Agreement and Plan of Merger, MidSouth merged with and into a wholly-owned
subsidiary of the Company, all of the outstanding shares of capital stock of
MidSouth were converted into the right to receive, in the aggregate,
approximately $2.5 million in cash and 272,521 shares of Common Stock and
MidSouth became a wholly-owned subsidiary of the Company.     
 
RESULTS OF OPERATIONS
   
  As a result of the Company's recent acquisitions and limited period of
affiliation with PHC Practices, the Company believes that the period-to-period
comparisons and percentage relationships within the periods set forth below
are not meaningful. The Company acquired its first PHC Practice in November
1996. The Company acquired 11 additional PHC Practices during the first nine
months of 1997. Changes in results of operations for the year ended December
31, 1996 as compared to the year ended December 31, 1995 and for the nine
months ended September 30, 1997 as compared to the nine months ended September
30, 1996 were caused primarily by the acquisitions of those PHC Practices.

  Nine Months Ended September 30, 1997 Compared to Nine Months Ended September
30, 1996     
   
  Net revenue increased to $15.9 million for the nine months ended September
30, 1997 from $2.7 million for the same period in 1996, an increase of $13.3
million or 488%. This increase was primarily due to approximately $11.6
million in additional revenues from the 12 PHC Practices acquired since
November 1996. This additional revenue was comprised of approximately $1.8 in
management fee revenue, approximately $1.9 in net patient revenues related to
employed physicians, and approximately $7.9 million in reimbursement of
clinical operating expenses. The remaining increase of approximately $1.5
million was due primarily to the start-up of global risk contracting in
September 1996, increased capitation contract revenues and revenues generated
by five new employee physicians in the Orlando market.     
   
  Salaries and benefits increased to $4.9 million for the nine months ended
September 30, 1997 from $2.1 million for the same period in 1996, an increase
of $2.8 million or 130%. The addition of staff related to the acquisitions of
12 PHC Practices constituted approximately $4.0 million of this increase.
Approximately $370,000 of this increase related to the addition of five
physician employees in the Orlando market. Additional amounts of approximately
$376,000 related to the addition of staff in support of growth in revenues. As
a percentage of net revenues, salaries and benefits expense decreased to 31%
for the nine months ended September 30, 1997 from 78% for the same period in
1996.     
   
  Contract and professional services expense increased to $746,000 for the
nine months ended September 30, 1997 from $370,000 for the same period in
1996, an increase of $376,000 or 102%. This increase was primarily due to the
acquisitions of six PHC Practices as well as increased legal fees associated
with new capitated contracts. As a percentage of net revenues, contract and
professional services expense decreased to 5% for the nine months ended
September 30, 1997 from 14% for the same period in 1996.     
   
  Provision for bad debts increased to $938,000 for the nine months ended
September 30, 1997 from $104,000 for the same period in 1996, an increase of
$388,000 or 797%. This increase primarily related to reserves established
based on historical collection experience for accounts receivable generated by
PHC Practices. As a percentage of net revenues, provision for bad debts
increased to 6% for the nine months ended September 30, 1997 from 4% for the
same period in 1996.     
   
  General and administrative expenses increased to $11.9 million for the nine
months ended September 30, 1997 from $1.2 for the same period in 1996, an
increase of $10.7 million or 857%. This increase was due to the asset
acquisitions of PHC Practices, the addition of four physician employees in the
Orlando market, as well as other increases in staffing levels. As a percentage
of net revenues, general and administrative     
 
                                      34
<PAGE>
 
   
expenses increased to 74% for the nine months ended September 30, 1997 from
45% for the same period in 1996.     
   
  Depreciation and amortization expense increased to $732,000 for the nine
months ended September 30, 1997 from $81,000 for the same period in 1996, an
increase of $651,000 or 804%. This increase was directly related to fixed
assets and goodwill acquired in the acquisitions of six PHC Practices. As a
percentage of net revenues, depreciation and amortization expense increased to
4% for the nine months ended September 30, 1997 from 3% for the same period in
1996.     
   
  The write down of assets for the nine months ended September 30, 1997
relates to the expense of certain loan issuance costs related to a terminated
credit arrangement.     
   
  Purchased research and development expense for the nine months ended
September 30, 1997 relates to a non-recurring expense of writing off an
intangible asset of a PHC Practice acquired in June 1997 based on management's
assessment that such asset had no future alternative benefit for the Company.
       
  Interest expense increased to $1.8 million for the nine months ended
September 30, 1997 from $1,000 for the same period in 1996. The increase was
due to the debt incurred in connection with asset acquisitions and working
capital borrowings.     
   
  As a result of the foregoing, net loss increased to $16.8 million for the
nine months ended September 30, 1997 from $1.2 million for the same period in
1996.     
 
  Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
  On November 3, 1995, the Company acquired the Predecessor by merger. Prior
to such acquisition, the Company did not have significant operations. The
Predecessor commenced operations in 1994. The operations for 1995 for the
Predecessor and the Company have been combined for presentation purposes. The
combined presentation is not in accordance with generally accepted accounting
principles.
 
  Net revenue increased to $4.0 million in 1996 from $2.4 million in 1995, an
increase of $1.6 million or 66%. This increase was due primarily to an
increase in single specialty contracting as well as the commencement of global
risk contracting in September 1996. Additionally, a portion of the increase
relates to the acquisition of Metropolitan Plastic & Reconstructive Surgery,
Ltd. ("Metropolitan Plastic") in November 1996.
 
  Salaries and benefits increased to $2.9 million in 1996 from $1.9 million in
1995, an increase of $1.0 million or 53%. This increase was due to additional
staffing added to support the growth in revenues as well as the hiring of
employees of Metropolitan Plastic in November 1996. As a percentage of net
revenues, salaries and benefits expenses decreased to 72% for 1996 compared to
79% for 1995.
 
  Contract and professional services expense was $194,000 in 1996 compared to
$195,000 in 1995. As a percentage of net revenues, contract and professional
services expense decreased to 5% in 1996 from 8% in 1995.
   
  Provision for bad debts increased to $660,000 in 1996 from $40,000 in 1995,
an increase of $620,000 or 1550%. This amount primarily related to reserves
established for contracts that were entered into by the predecessor and did
not conform to the Company's business plan.     
 
  General and administrative expenses increased to $2.7 million in 1996 from
$594,000 in 1995 an increase of $2.1 million or 355%. This increase was
related to increased staffing levels for anticipated growth in 1997 as well as
the acquisition of Metropolitan Plastic. As a percentage of net revenues,
general and administrative expenses increased to 68% for 1996 compared to 25%
for 1995.

  Depreciation and amortization expenses increased to $161,000 in 1996 from
$120,000 in 1995, an increase of $41,000 or 34%. This increase was directly
related to fixed assets and goodwill acquired in connection with an
acquisition of Metropolitan Plastic. As a percentage of net revenues,
depreciation and amortization expenses decreased to 4% for 1996 from 5% in
1995.
 
  The write down of assets in 1996 relates to the write off of operating
assets related to certain terminated physician arrangements.
 
  Interest expense decreased to $30,000 in 1996 from $93,000 in 1995, a
decrease of $63,000. The decrease was due to the reduction of certain above-
market rate debt.
 
  As a result of the foregoing, net loss increased to $2.9 million in 1996
from $531,000 in 1995.
 
  Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
  Net revenue increased to $2.4 million in 1995 from $812,000 in 1994, an
increase of $1.6 million or 197%. The increase was due to an increase in the
number of payor contracts administered in 1995.
 
  Salaries and benefits increased to $1.9 million in 1995 from $531,000 in
1994, an increase of $1.4 million or 263%. The increase was due to an increase
in the number of employees to administer payor contracts. As a percentage of
revenues, salary and benefits expenses increased to 79% in 1995 from 65% in
1994.
 
  Contract and professional services expense increased to $195,000 in 1995
from $37,000 in 1994, an increase of $158,000 or 427%. As a percentage of
revenues, contract and professional services expense increased to 8% in 1995
from 5% in 1994.
 
  Provision for bad debts increased to $40,000 in 1995 from $0 in 1994.
 
  General and administrative expenses increased to $594,000 in 1995 from
$225,000 in 1994, an increase of $369,000 or 164%. As a percentage of
revenues, general and administrative expenses decreased to 25% in 1995 from
28% in 1994.
 
  Depreciation and amortization expenses increased to $120,000 in 1995 from
$58,000 in 1994, an increase of $62,000 or 107%. As a percentage of revenues,
depreciation and amortization expenses decreased to 5% in 1995 from 7% in
1994.
 
  Interest expense increased to $93,000 in 1995 from $24,000 in 1994, an
increase of $69,000 or 288%. The increase was due to the acquisition debt
incurred to purchase the Predecessor.
 
  As a result of the foregoing, net loss increased to $531,000 in 1995 from
$63,000 in 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
   
  At September 30, 1997, working capital was $(5.2) million, a decrease of
$5.4 million during the first nine months of 1997, and cash and cash
equivalents were $5.2 million. At September 30, 1997, net accounts receivable
increased to approximately $8.1 million compared to approximately $465,000 at
December 31, 1996. The increase is attributable to growth in revenues and
acquired assets due to the acquisition of PHC Practices.     
   
  Capital expenditures during the first nine months of 1997 totaled
approximately $341,000. The Company is committed to make specified levels of
capital expenditures under certain of its Practice Management Agreements.     
 
  During June 1997, the Company completed a private placement of its Series B
Preferred Stock (the "Series B Offering"). Pursuant to the Series B Offering,
the Company received net proceeds of approximately
 
                                      36
<PAGE>
 
   
$9.8 million at the initial closing in June 1997 (substantially all of which
was used in connection with the acquisition of the assets of the Arlington
Cancer Center by the Company). At the second closing in July 1997,
approximately $5.5 million was deposited into an escrow account which was
accessed by the Company in connection with its acquisition of practices
meeting certain agreed upon criteria. Although the Company expects to retire
approximately $6.2 million in indebtedness incurred in connection with the
Arlington Cancer Center acquisition with the proceeds of the Offering, the
Company has the ability instead to require the holders of its Series B
Preferred Stock to purchase shares of Common Stock at $4.00 per share
sufficient to retire this indebtedness in April 1998, pursuant to an equity
call agreement.     
   
  In October 1997, the Company entered into a credit agreement with a group of
banks led by Banque Paribas (the "Bank Group") under which agreement, as
amended and restated in December 1997, the Bank Group agreed to provide the
Company with up to $62.5 million in senior debt (the "Senior Facility"). The
Senior Facility is comprised of a term loan in an amount up to $20.0 million
(the "Term Loan"), a revolving loan in an amount up to $10.0 million (the
"Revolving Loan") and an acquisition loan in an amount up to $32.5 million
(the "Acquisition Loan"). The Senior Facility is secured by substantially all
of the Company's assets. At December 31, 1997, approximately $12.0 million was
outstanding under the Term Loan, approximately $1.5 million was outstanding
under the Revolving Loan and approximately $1.1 million was outstanding under
the Acquisition Loan. In connection with the Senior Facility, the Company sold
to Paribas Principal Incorporated ("PPI"), an affiliate of Banque Paribas, for
approximately $2.2 million, 553,683 shares of Series B Preferred Stock and
warrants exercisable for 58,090 shares of Common Stock at a nominal exercise
price. Further, in October 1997, the Company obtained from Paribas Capital
Funding LLC ("PCF"), an affiliate of Banque Paribas, a senior subordinated
loan (the "Subordinated Loan") in the amount of $15.0 million (of which $9.0
million was advanced), and sold to PCF warrants exercisable for 376,800 shares
of the Company's Non-Voting Common Stock. If the Company completes an initial
public offering by February 27, 1998 or April 27, 1998, respectively, PCF will
forfeit warrants exercisable for 226,080 or 188,400 shares of Non-Voting
Common Stock, respectively, retaining warrants exercisable for 150,720 or
188,400 shares of Non-Voting Common Stock, respectively. The Company will
repay the Subordinated Debt with the net proceeds of the Offering and will use
$12.0 million of such net proceeds to repay indebtedness under the Term Loan.
Commitments under the Term Loan will be extinguished upon repayment. Following
such required repayments, such financing must be paid down with excess cash
flow. Following repayment of the indebtedness, neither the Bank Group nor the
Company's subordinated lenders will have any obligation to advance additional
funds to the Company.     
 
  The Company historically has funded its acquisitions and operations through
cash flow from operations, borrowings and sales of equity securities. In
addition to the proceeds from the offering, funds available under its bank
borrowings, cash reserves and cash flow from operations, the Company expects
to incur, from time to time, short-term and long-term bank indebtedness and to
issue equity and debt securities, the availability and terms of which will
depend upon market and other conditions, to meet the Company's current planned
acquisition, capital expenditure and working capital needs for the next 12
months and to provide the funds necessary for the continued pursuit of the
Company's long-term expansion strategy. There can be no assurance that such
additional financing will be available on terms acceptable to the Company.
 
RECENT PRONOUNCEMENTS
       
       
   
  New Accounting Pronouncements     
   
  In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings Per Share." SFAS No. 128 is designed to improve the
earnings per share information provided in the financial statements by
simplifying the existing computational guidelines, revising the disclosure
requirements, and increasing the comparability of earnings per share data.
SFAS No. 128 is effective for periods ending after December 15, 1997,
including interim periods. The Company will adopt SFAS No. 128 for the fiscal
and interim     
 
                                      37
<PAGE>
 
   
periods ending December 31, 1997. As of September 30, 1997, the disclosure
requirements of SFAS No. 128 would not require a different presentation of
earnings per share than currently presented due to the antidilutive effect of
all common stock equivalents.     
   
  In February 1997, the Financial Accounting Standards Board issued SFAS No.
129, "Disclosure of Information About Capital Structure." SFAS No. 129
requires companies to disclose descriptive information about an entity's
capital structure. It also requires disclosure of information about the
liquidation preference of preferred stock and redeemable stock. SFAS No. 129
is effective for the Company's fiscal year ending December 31, 1998. The
Company does not expect that SFAS No. 129 will require significant revision of
prior disclosures.     
   
  In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income." SFAS No. 130 is designed to improve the
reporting of changes in equity from period to period. SFAS No. 130 is
effective for fiscal years beginning after December 15, 1997. The Company will
adopt SFAS No. 130 for fiscal 1998. Management does not expect SFAS No. 130 to
have a significant impact on the Company's financial statements.     
   
  In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information." SFAS
No. 131 requires that an enterprise disclose certain information about
operating segments. SFAS No. 131 is effective for financial statements for the
Company's fiscal year ending December 31, 1998. The Company does not expect
that SFAS No. 131 will require significant revision of prior disclosures.     
   
  The Emerging Issues Task Force of the FASB has recently issued its Consensus
Opinion 97-2 ("EITF 97-2"). EITF 97-2 addresses certain specific matters
pertaining to the physician practice management industry. EITF 97-2 would be
effective for the Company for its year ending December 31, 1998. EITF 97-2
addresses the ability of physician practice management companies to
consolidate the results of physician practices with which it has an existing
contractual relationship. The Company is still in the process of analyzing the
effect on all of its contractual relationships, but currently believes that
certain contracts would meet the criteria of EITF 97-2 for consolidating their
results of operations, which would require the Company to restate its
financial statements to reflect such consolidation. EITF 97-2 also has
addressed the accounting method for future combinations with individual
physician practices. The Company believes that, based upon the criteria set
forth in EITF 97-2, virtually all of its future acquisitions of individual
physician practices will continue to be accounted for under the purchase
method of accounting.

OVERVIEW
   
  Physician Health Corporation is a physician management company focusing on
the value-added integration of practice management, ancillary health care
services, network development and administration, and payor contracting in
selected markets. As of December 31, 1997, the Company provided payor contract
administration and related services to 23 Affiliated Networks and two PHC
Networks. The PHC Networks and Affiliated Networks included approximately
3,300 physicians and had approximately 2.3 million covered lives under 29
managed care contracts including specialty capitation contracts and global
risk contracts. As of December 31, 1997, the Company also provided practice
management services to 34 PHC Practices, including 171 PHC Physicians. The
Company was a party to Practice Management Agreements with 26 of the PHC
Practices that employed 113 PHC Physicians. The Company directly owned and
operated the remaining eight of the PHC Practices through which it directly
employed 58 PHC Physicians.     
          
  The Company's objective is to continue building comprehensive and integrated
networks of physicians in selected regional markets in order to: (i) establish
a significant market presence enabling it to negotiate favorable payor
contracts and (ii) provide a broad range of physicians and ancillary health
care services to payors and patients. To achieve these objectives, the Company
seeks to: (a) leverage contracting expertise to enhance its strategic position
in its markets; (b) selectively acquire key practices to strengthen market
presence; (c) provide management expertise and capital for development of
ancillary health care services; (d) negotiate and administer beneficial payor
contracts; and (e) utilize information technology to improve practice
performance and meet payor requirements and patient needs. The Company
believes that the expertise of its management team in network development,
payor contracting and ancillary health care services, as well as PHC's
flexible approach to entering new markets and structuring its operations,
differentiates it from traditional physician practice management companies
("PPMs") and enhance its ability to attract physicians and to negotiate
favorable payor contracts. PHC's acquisition of key practices is a part of its
overall strategy of strengthening its networks and market presence and
enhancing the Company's ability to contract with managed care payors and
providers.     
   
  The Company commenced operations in 1994 as a wholly-owned subsidiary of
Surgical Health Corporation. PHC was incorporated in Delaware in August 1995
and acquired the Predecessor in November 1995. Prior to the acquisition of the
first PHC Practice in November 1996, the Company principally engaged in
network development and administration, payor contracting, practice
administration, and development activities related to potential acquisitions.
The Company's current regional markets are centered in Atlanta, Georgia;
Cincinnati, Ohio; Dallas/Ft. Worth, Texas; Memphis, Tennessee; Orlando,
Florida; and St. Louis, Missouri. The Company also provides services in
Alabama, Arizona, Illinois, Kentucky, Mississippi and Virginia.     
 
INDUSTRY BACKGROUND
 
  The Health Care Financing Administration ("HCFA") has estimated that
national health care spending increased to approximately $1.0 trillion, or
approximately 14% of GDP, in 1995 from $247 billion, or approximately 9% of
GDP, in 1980. HCFA projects that annual health care spending will increase at
a compounded annual growth rate of over 8% to $1.5 trillion and approximately
16% of the GDP by the year 2000. HCFA also has estimated that approximately
$200 billion, or approximately 20%, of total health care expenditures, in 1995
were directly attributable to physician services, and an additional amount of
approximately $515 billion or 52% of such expenditures were under physician
direction.
   
  As a result of escalating health care expenditures, governmental and other
payors have adopted cost containment initiatives in an effort to control
spending. These initiatives have resulted in a shift from traditional fee-for-
service provider reimbursement to an evolving array of managed care
arrangements, varying from discounted fee-for-service to fully capitated plans
in which providers assume the financial risks related to service utilization
for a defined group of covered members and services. The industry has also
experienced a decrease in inpatient occupancies as payors have implemented
incentives for providing care in a more cost-effective setting, which is often
an outpatient surgery center, in-office laboratory or similar outpatient
location.     
 
                                      39
<PAGE>
 
   
  Cost-containment initiatives, including reduced reimbursement, have hindered
physician practice profitability while demands for increased clinical
documentation, cost, quality and utilization data have increased physicians'
administrative duties. Small and mid-sized practices generally do not have the
market presence, expertise or sophisticated cost accounting and quality
management systems required, and may not have the time necessary, to evaluate
and enter into informed capitated risk-sharing arrangements or to continue
practicing profitably under reduced reimbursement. In addition, these
practices often lack the capital required to purchase new medical equipment
and information systems to enhance the efficiency and quality of their
practices. As a result, individual physicians and small group practices are
increasingly consolidating, either by affiliating with larger group practices
and PPMs or by forming networks or independent practice associations. By
consolidating into larger organizations, physicians can achieve lower
administrative costs, gain leverage in negotiating with managed care
organizations and position themselves to attract needed capital resources.
       
  Although the larger organizations resulting from these consolidations have
often improved practice profitability through reductions in overhead and
centralization of certain administrative functions, the Company believes that
many such organizations lack the expertise and market presence to negotiate
successful managed care contracts. In addition, the Company believes that many
PPMs do not offer opportunities for practices and physicians to integrate
complementary ancillary health care services and share in the resulting
income.     
 
THE PHC PHILOSOPHY
   
  The Company seeks to affiliate with physicians who are leaders in the
delivery of medical care and who apply sound business principles to the
operation of their practices. The Company believes that physicians are best
qualified to develop appropriate treatment protocols, and as a result, the
Company provides PHC Physicians, PHC Networks and Affiliated Networks with the
resources necessary to enhance their decision making. The Company also
believes that health care is essentially a regional or local business.
Therefore, PHC aims to integrate practice management, ancillary health care
services, network development and administration and payor contracting at a
regional level. Through such integration and by supporting physicians with
strong, experienced local management teams, the Company believes it provides
physicians with the tools necessary to compete in a changing and increasingly
competitive health care environment.     
 
STRATEGY
   
  The Company's objective is to continue building comprehensive and integrated
networks of physicians in selected regional markets in order to: (i) establish
a significant market presence enabling it to negotiate favorable payor
contracts and (ii) provide a broad range of providers to payors and patients.
To achieve its objectives, the Company seeks to:     
   
  Leverage Contracting Expertise to Enhance its Strategic Position in its
Markets. The Company enters markets both by providing network development and
contracting services and, in certain cases, by acquiring practices that the
Company believes can serve as foundations for future networks. As it enters
markets, the Company seeks to form comprehensive provider panels and provide
managed care contracting services to physician practices and networks in order
to gain negotiating leverage with payors and to achieve economies of scale.
The Company believes its network development and contracting services model
enables it to establish a significant market platform with less initial
management time and capital than PPM models based solely on acquisitions. In
addition, the Company believes its network development and contracting
expertise enhances its credibility with market participants and enables it to
identify new markets in which managed care contracting is likely to grow and
the key practices in these markets. Where appropriate, the Company enters a
new market through selective acquisitions of such key practices.     
 
  Selectively Acquire Key Practices to Strengthen Market Presence. The Company
selectively acquires key physician practices from its networks and from the
suburban and rural communities surrounding these markets to solidify its
market position, to strengthen its existing networks and to establish,
organize and support new networks. Through network development and contracting
services, the Company establishes relationships with
 
                                      40
<PAGE>
 
   
physicians and identifies leading physicians and practices who apply sound
business principles and are attractive to patients and payors. By acquiring
physician practices from within its networks or existing markets, the Company
believes it makes informed decisions about practice acquisitions and the
allocation of capital resources. The Company also may acquire non-network
practices that it believes will serve as foundations for building new
networks. PHC's acquisition of key practices is a part of its overall strategy
of strengthening its networks and market presence and enhancing the Company's
ability to contract with managed care payors and providers.     
   
  Provide Management Expertise and Capital for Development of Ancillary Health
Care Services. The Company intends to acquire and develop ancillary health
care services in order to improve the revenues and operating margins of the
Company and the PHC Practices. The Company believes that the availability of
ancillary health care services provides physicians with scheduling flexibility
and greater practice efficiency. Additionally, ancillary health care services
provided in an outpatient setting are attractive to payors because they
generally are less expensive than similar inpatient services. By providing
ancillary health care services, the Company also increases its flexibility in
negotiating global risk contracts. The Company's management team has
experience in the successful development of outpatient surgery centers and
other ancillary health care services.     
 
  Negotiate and Administer Beneficial Payor Contracts. The Company focuses on
negotiating and administering payor contracts on behalf of the PHC Practices,
Affiliated Networks and PHC Networks. The Company believes that its
contracting expertise helps it develop and improve relationships with
physicians and payors, and that its contracting services can result in
increased revenues and profits for PHC, the PHC Physicians, PHC Practices, PHC
Networks and Affiliated Networks. The Company believes that its strategy of
providing network development and administration services and specialty and
other contracting services also enables it to establish: (i) a strong market
position; (ii) stable networks of high quality providers; (iii) strong payor
relationships; (iv) integration of ancillary health care services; and (v)
access to cost, quality and utilization data, all of which are essential to
entering into profitable partial and global risk contracts.
   
  Utilize Information Technology to Improve Practice Performance and Meet
Payor Requirements and Patient Needs. The Company intends to provide its
physicians access to information and technologies that will enhance their
ability to deliver care more efficiently and profitably in a managed care
environment. The Company's clinical information system collects network data
that enable it to price and manage specialty capitation contracts as well as
partial and global risk contracts. The system also provides a broad range of
statistical data to support utilization analysis, to identify physician
outliers and to develop practice protocols. With the data it collects, the
Company can also meet various requirements of payors, including supplying
information to support accreditation of providers and networks by health care
industry organizations such as the National Committee for Quality Assurance
("NCQA") and the Utilization Review Accreditation Committee ("URAC").     
 
OPERATIONS
   
  PHC acquires and manages practices, acquires or develops and manages
ancillary health care services, develops and administers networks, and
negotiates and administers payor contracts in its selected markets. In
choosing new markets, the Company analyzes the population, demographics,
market potential, competitive environment, supply of physicians, needs of
managed care plans or other large payors and general economic conditions. The
Company seeks markets in which it believes it can achieve a significant market
share and, in particular, in which there is evidence of risk shifting from
payors to providers. PHC enters new markets where it has identified an
opportunity or where payors or providers have requested its services.

  The following table sets forth certain information regarding the PHC
Networks, Affiliated Networks, PHC Physicians and the managed care contracts
administered by the Company as of December 31, 1997. Markets identified as
integrated regional markets are those in which the Company has affiliated with
a network and has acquired selected PHC Practices affiliated with the
contracting networks. Developing regional markets are those in which the
Company has affiliated with PHC Physicians but does not yet manage a
corresponding network. Additional contracting markets are those in which PHC
is administering active managed care contracts and has not yet determined
whether to seek physician practice acquisitions. For additional detailed
information regarding individual networks and practices see Appendix A.

  Practice Acquisition and Management
   
  A part of the Company's strategy is to acquire leading medical practices in
markets in which the Company believes it can establish a significant market
presence and in which it provides significant contracting services and has
significant local management relationships. The Company selectively acquires
key physician practices from its networks and from the suburban and rural
communities surrounding these markets in order to solidify its market position
and strengthen its networks. Additionally, in markets where the Company has
identified an attractive opportunity, the Company will acquire selected
physician practices. PHC's acquisition of key practices is a part of its
overall strategy of strengthening its networks and market presence and
enhancing the Company's ability to contract with managed care providers.     
   
  The Company seeks to acquire practices of physicians who: (i) are viewed by
the Company as important to the long-term success of its networks; (ii) apply
sound business principles in the operation of their practices and are high
growth oriented; (iii) have reputations in the market as leaders in the
delivery of medical care; and (iv) embrace new medical technologies and
procedures. As part of this process, the Company often targets a particular
type of practice or specialty that the Company believes contains physician
leaders in the specific market.     
   
  The Company believes that the following characteristics differentiate it from
other alternatives available to physicians and physician networks and position
it to succeed in acquiring physicians and practices: (i) its contracting
expertise; (ii) the quality, experience and credibility of its local management
teams and its knowledge of the markets in which it operates; (iii) its
ancillary health care services expertise; (iv) its governance structure, which
fosters physician autonomy while promoting physician participation; and (v) its
flexible approach to entering new markets and structuring its operations.     
   
  Acquisition Process. The Company's business development team identifies,
pursues and negotiates practice acquisitions. After identifying a practice or
physician, the Company meets with the physicians to determine whether they meet
the Company's criteria and have an interest in affiliating with PHC. The
Company's business, financial and legal due diligence includes site visits,
analysis of financial and other data and analysis of the group's operations,
leadership, clinical practices and commitment to long-term growth.
Additionally, the Company reviews the medical professionals' training,
licensure and experience and the practice's Medicare and Medicaid compliance,
billing practices and operating history. Upon successful completion of due
diligence, the Company structures and negotiates the acquisition terms,
including the type and amount of consideration as well as noncompete
agreements. The consideration paid in the Company's acquisitions is designed to
align its interests with those of the physicians and includes a combination of
Company stock, cash and, sometimes, notes. The consideration for each practice
varies on a case-by-case basis, depending on a variety of factors including
historical operating results, the future prospects of the practice and the
ability of the practice to complement the services offered by other PHC
Practices. When the Company acquires the non medical assets of a physician
practice that it will not directly own, it generally purchases all of the
tangible and intangible assets of the practice with the exception of patient
medical records and real estate. Patient medical records are retained by the
selling practice or a new entity formed by the practice's physicians, and the
practice or new entity enters into a Practice Management Agreement in
connection with the acquisition. When the Company acquires a physician practice
that the Company will own, the Company generally purchases all of the tangible
and intangible assets of the practice, including medical records, and employs
the practice's physicians.     
 
  Practice Management Services. Pursuant to its Practice Management Agreements,
the Company provides a range of services including among other things: (i)
acting as manager and administrator of non-medical services relating to the
operation of the PHC Practice; (ii) billing patients, insurance companies and
other third-party payors and collecting the fees for professional medical
services and other services rendered and products sold by the PHC Practice;
(iii) providing, as necessary or requested, clerical, accounting, purchasing,
payroll, legal, bookkeeping and computer services and personnel, information
management, preparation of certain tax returns, printing, postage and
duplication services and medical transcribing services; (iv) supervising and
maintaining custody of substantially all files and records; (v) providing
facilities for the PHC Practice; (vi) preparing, in
 
                                       43
<PAGE>
 
   
consultation with a joint policy board and the PHC Practice, all capital
expenditure and operating budgets; (vii) ordering and purchasing inventory and
supplies as reasonably requested by the PHC Practice; and (viii) providing
financial and business assistance in the negotiation, establishment,
supervision and maintenance of contracts and relationships with managed care
and similar payors. Management fees payable to the Company under the Practice
Management Agreement are determined in arm's-length negotiations based on the
nature and amount of services provided. Many of the Company's services are
designed to reduce the amount of time physicians must spend on administrative
matters, thereby enabling the physicians to focus on the delivery of health
care. The Company also assists in the development of ancillary health care
services by conducting feasibility studies and providing project development
services and capital resources.     
   
  The Company employs most of the PHC Practices' non-physician personnel. These
non-physician personnel, along with additional personnel at the local
management level, manage the day-to-day non-medical operations of each of the
PHC Practices, including, among other things, secretarial, bookkeeping,
scheduling and other business services. In Florida, Missouri and other states
that permit the corporate practice of medicine, the Company may employ
physicians as well as non-physician personnel. The PHC Physicians in the owned
PHC Practices continue to control the medical aspects of the practice and have
input with respect to strategic planning and budgeting. PHC has direct
responsibility for all non-medical aspects of the operation of the owned PHC
Practices.     
 
  Ancillary Health Care Services
   
  In evaluating a market, the Company analyzes opportunities to develop or
acquire ancillary health care services. Where appropriate, PHC intends to
acquire and to develop ancillary health care services to complement its local
PHC Practices, PHC Networks and Affiliated Networks. Ancillary health care
services include those that are: (i) part of a practice such as a single-
purpose, office-based surgery suite; (ii) connected with a group practice,
which may consist of several otherwise independent practices, such as a
birthing center; or (iii) affiliated with a coherent specialty network such as
a lithotripter with a urologist network or a sleep lab with a network of
otolaryngology (ENT) physicians. The Company encourages physician participation
in these ancillary health care services, either through an ownership interest
in a joint venture established to own and operate a facility or through
clinical participation. The Company believes that ancillary health care
services provide physicians with scheduling flexibility and greater practice
efficiency. Additionally, ancillary health care services provided in an
outpatient setting are attractive to payors because they generally are less
expensive than similar inpatient services. By providing ancillary health care
services, the Company also increases its flexibility in negotiating global risk
contracts. The Company's management team has experience in the successful
development of outpatient surgery centers and other ancillary health care
services.     
   
  The structure of the financial interest held by the Company in ancillary
services delivered by the Company or the PHC Practices will differ based on the
Company's evaluation of the requirements of state laws prohibiting the
corporate practice of medicine, as well as federal and state anti-kickback and
self-referral laws. Where legally permissible, the Company may own all or part
of an ancillary health care service provider. In other instances the Company
may manage the delivery of ancillary health care services through a PHC
Practice in exchange for a management fee.     
   
  Currently, the Company has an interest in a wholly-owned sleep laboratory
located in Atlanta, Georgia and a 51% partnership interest in an ambulatory
surgery center located in Orlando, Florida. The Company derives revenue from
the sleep laboratory through the conduct of sleep studies and the sale of
durable medical equipment related to sleep disorders. Revenues from the
ambulatory surgery center are derived from facility fees charged by the center.
The Company also manages this ambulatory surgery center for a fee of 6% of the
revenues of the ambulatory surgery center. The Company has options, commencing
in June 1998, to purchase a 51% interest in two other ambulatory surgery
centers located in Orlando, Florida.     
       
  Network Services
   
  Network Formation and Development. In forming networks, the Company focuses
on developing networks of sufficient size and specialties to respond
successfully to payors' geographic, service and utilization     
 
                                       44
<PAGE>
 
   
management needs. The Company contacts physicians that it believes offer the
medical expertise and quality of care that are attractive to payors. In both
network formation and network development, the Company assists physicians in
determining the number and types of specialists, subspecialists and hospitals
required for a network to be attractive to payors and to meet the needs of a
particular payor's contract. The Company then aids in selecting and
credentialing the panel of physicians. After the panel of physicians is
selected, the Company assists in forming protocol, finance, utilization,
credentialing and quality assurance (peer review) committees composed of
network physicians. In addition, the Company assists physicians in developing
or revising protocols, although physicians in each network retain ultimate
responsibility for selecting and adopting appropriate protocols for their
market. In the PHC Network model, network physicians contract directly with the
PHC Network to provide medical services. The physicians do not contract among
themselves, except where they may have formed their own group practices. In the
PHC Network model, each physician must elect to participate in any new managed
care agreement, although the Company is attempting to shift its model to one in
which the network is permitted to commit its providers to providing services
under managed care contracts. For the Affiliated Networks, the Company
contracts with the network to provide services to the network. No contracts are
executed between the Company and the Affiliated Network physicians.     
   
  Network Services Agreements. The Company provides a variety of services to
physician networks under its network services agreements. Networks can elect to
receive all or only a selection of the available services, which include
network formation and development, contract marketing, negotiation and pricing,
contract administration and other custom services, as further described below.
Some networks request the Company's assistance with the earliest stages of
building the network and others already have executed managed care agreements
prior to hiring the Company for administrative and claims processing services.
Fees paid to the Company under the network services agreements are generally
structured as a percentage of payments made by the payor to the network. The
precise percentage depends on the nature and extent of services provided, and
currently ranges from 4.5% to 10.0%. For capitated and other financial risk-
sharing contracts that are directly held by the Company, the service fee is in
addition to amounts that may be earned by the Company through management of
utilization resulting in an excess of payments from the payor over provider
claims.     
   
  Contract Marketing, Negotiation and Pricing. An integral element of the
Company's network services is its contracting expertise. The Company also can
provide marketing services such as conducting payor surveys to determine payor
interest in managed care contracting in the market, preparing descriptive
materials and marketing the networks to payors. Once interest is established,
the Company's contracting team, on behalf of the network, works closely with
physicians to prepare contract proposals, analyze contract pricing and
negotiate with payors. The Company has developed a database of managed care
cost and utilization information collected from its networks that it can
utilize to predict the type and quantity of services that will be required by
many different types of contracts. Based upon this information, the Company is
able to formulate different service offerings and pricing models for use in
contract negotiations.     
   
  Contract Administration Services. After a network executes a contract, the
Company implements and administers the contract on behalf of the network and
serves as the interface between the network physicians and the payor. The
Company prepares an administrative manual for each managed care contract for
use by the providers, provides claims processing and utilization reporting
services, administers and distributes funds, and assists in designing
compensation methods and schedules for the network providers consistent with
the managed care environment. Claims processing services generally include
verification of claim eligibility, matching claims to pre-certification
approvals, reviewing claims for completeness, providing coordination of
benefits services, submitting claims to payors, acting as an interface among
the network, providers and payors with respect to claims issues, maintaining an
accounting of amounts due from and paid by payors, calculating amounts due to
providers, preparing explanations of benefits ("EOBs") and, if requested by the
network, distributing EOBs and payments to network participants.     
   
  The Company believes that managed care contracts are most successful when the
economic interests of the providers and payors are aligned. Therefore, the
Company works with both the network and the payor to develop payment structures
and protocols that encourage optimization of facility usage through the use of
the most     
 
                                       45


<PAGE>
 
   
appropriate type of facility for each procedure, often reducing overall
facility costs. The Company's standard form of reports relating to incidence
rates, utilization, flow of funds and treatment outcomes are included in most
packages, with custom reports available for an additional fee. Such information
is used by both the network and the payors in developing or refining protocols,
identifying physician outliers, ensuring that standards of care are met,
determining cost-effective treatment plans and meeting NCQA and Health Employer
Data Information System requirements. Additional custom services may include
conducting adverse outcome and patient and provider satisfaction surveys, as
well as conducting site surveys, record reviews and education and consulting
services to meet NCQA level compliance. The Company is URAC certified, which
enables the Company to manage the pre-admission certification process for major
procedures and hospital stays under the supervision of the network's physician
medical director.     
   
  Managed Care Contracts. As of December 31, 1997 all of the capitated and
other financial risk-sharing contracts managed by the Company for Affiliated
Networks were directly between the Affiliated Network and the payor. Under this
structure, the affiliated network and the providers directly benefit if
decreased utilization of medical services results in a surplus of funds
available to pay providers, and have the risk that increased utilization will
result in funding deficiencies that could result in decreased reimbursement to
the providers. Payments by payors under the managed care agreements are made
either directly to the network, or to the Company on behalf of the network, and
the Company is paid its percentage management fee out of such funds. As of
December 31, 1997, the Company, through a 51% owned subsidiary, directly holds
three global risk contracts for which services are provided largely by
agreement with the non-profit PHC Network. The PHC Network providers are paid
by the Company on a fee-for-service basis. Thus, the Company both receives the
financial benefit of decreased utilization and takes the primary risk of
increased utilization. Some PHC Practices individually are parties to specialty
capitated contracts directly with payors. As a result, the Company also manages
these capitated contracts.     
   
  The Company is experienced in negotiating and implementing a variety of
managed care contracts, including single- and multi-specialty capitated
contracts, partial risk contracts and global risk contracts. Single-specialty
capitated contracts are contracts that carve out treatment by physicians of a
single medical specialty. Multi-specialty capitated contracts usually involve a
range of specialists required to provide a defined spectrum of care. The
network is usually paid on a capitated per member per month basis for both
single- and multi- specialty capitated contracts, and in some cases the
contracts also have a facility/total cost share component. Partial risk
contracts are contracts for most professional services of most physician
specialties to be rendered to the plan members but do not include the provision
of facility-based care. If the network lacks specialties it must expand or
subcontract with a single- or multi-specialty network to provide such services.
Global risk contracts are contracts for all professional, technical and
facilities services, supporting a spectrum of health care needs for plan
members. The network may be paid on either a capitated per member per month
basis or on a percentage of premium basis for both partial risk and global risk
contracts and the contracts have a facility/total cost share component.     
   
  In addition to the types of managed care contracts discussed above, the
Company administered one disease state management contract covering 60 lives
and two access fee contracts as of December 31, 1997. Disease state management
contracts are contracts for professional services and facilities necessary to
provide the full spectrum of services required to treat a chronic disease. The
network is paid either on a capitated per member per month basis or on a case
rate basis. Access fee contracts are contracts pursuant to which the Company
makes available physicians in one of its networks to a payor on a fee-for-
service basis. A physician invoices the payor if and when services are
provided. The Company receives a percentage of the physician's reimbursement as
an access fee.     
   
  The Company began administering its first specialty capitated contract in
June 1994 and its first global risk contract in September 1996. Company
employees have expertise in managed care contracting. The Company's Executive
Vice President of Networking and Contracting has been negotiating and managing
capitated and risk-sharing managed care contracts since 1982. The Company's
Senior Vice President of Specialty Contracting has negotiated and managed at
least 50 single specialty capitated contracts since 1990 with the assistance of
one of the contracting division's vice presidents, who specializes in
utilization data management and reporting.     
 
                                       46
<PAGE>
 
   
Additional team members include a divisional Vice President with ten years of
managed care experience, including network and contract administration,
operations and claims and a recently hired divisional Assistant Vice President
with four years of experience in network management and managed care contract
administration, including management of at least five global contracts. As of
December 31, 1997, the Company had 29 managed care contracts with
approximately 2.3 million covered lives. For the nine months ended September
30, 1997, the Company received 10% on a historical basis, and 2% or a pro
forma basis, of its total revenues from direct contracts with managed care
payors.     
 
MANAGEMENT INFORMATION SYSTEMS
   
   Upon the acquisition of a practice, the Company maintains the clinical
medical records and financial systems in place at the PHC Practice. Clinical
and financial data collected at the practice are sent to the Company's
corporate headquarters on a monthly basis through network interfaces,
electronic data interchange or manually. The Company intends to maintain local
systems in an effort to minimize the disruption that can occur when local
systems are replaced with corporate-mandated systems. The Company uses its
management information systems to generate information that will assist the
PHC Practices in the maintenance and selection of appropriate practice
protocols, and in the management of quality improvement procedures and
utilization. The Company currently collects cost and utilization data from the
PHC Networks and Affiliated Networks for managed care contract pricing and
administration, and intends to collect such data at the PHC Practices. The
Company intends also to use this information to improve operating efficiency
and to encourage the development and implementation of best clinical
practices.     
 
GOVERNANCE AND QUALITY ASSURANCE
   
  The Company's current governance structure promotes physician participation
in the management of the Company. Certain physicians who are or have been
associated with PHC Practices serve on the Board of Directors. Each PHC
Practice has a Joint Policy Board whose membership includes physician
representatives from the Company and the PHC Practice. The Joint Policy Boards
have responsibilities that include developing long-term strategic objectives,
developing practice expansion and payor contracting guidelines, promoting
practice efficiencies, recommending significant capital expenditures and
facilitating communication and information exchange between the Company and
each of the PHC Practices.     
   
  The Company has established a Compliance Committee of the Board of Directors
that consists of physician and management members of the Board. The Compliance
Committee is responsible for approving the Company's health care compliance
objectives and developing and implementing the Company's health care
compliance programs at the practice and Company level. To facilitate this
process, the Company is establishing compliance committees at the PHC Practice
level comprised of representatives of the PHC Practice and the Company to
oversee development and implementation of compliance programs at the PHC
Practice level. Through counsel, the Company has retained outside consultants
to assist with practice and Company assessments that will assist the
Compliance Committee of the Board of Directors, the local compliance
committees and management in developing the Company's compliance programs.
    
CONTRACTUAL AGREEMENTS WITH PHC PRACTICES
 
  The Company's practice acquisition structure is designed to align the
interests of the Company with those of PHC Physicians. When a physician group
has agreed to enter into a practice management or employment relationship with
the Company, the Company purchases the group's operating assets typically in
exchange for a combination of Company stock, cash and notes. The Company
intends to continue to use Common Stock as a significant portion of its
consideration in future practice acquisitions. Typically, upon the acquisition
of a PHC Practice, the Company enters into a Practice Management Agreement
with a professional corporation or other entity that will employ the
physicians associated with the PHC Practice.
 
  The following summary is intended to be a brief summary of the typical terms
of Practice Management Agreements, Physician Employment Agreements and Direct
Employment Agreements to which the Company or a
 
                                      47
<PAGE>
 
PHC Practice is a party and intends to enter in the future. The actual terms of
these agreements vary on a case by case basis, depending on the negotiations
with the individual practices and physicians.
   
  Service Fees. Management fees payable to the Company under the Practice
Management Agreements are determined in arm's-length negotiations and based on
the nature and amount of services provided. Such fees generally consist of
combinations of the following: (i) percentages (generally ranging from 10% to
25%) of the earnings of the PHC Practices; (ii) operating and non-operating
expenses of the PHC Practices paid by the Company pursuant to the Practice
Management Agreements; and (iii) certain negotiated performance and other
adjustments. In the case of the Arlington Cancer Center, the Company's
management fee is 12% of the practice's revenues plus 55% of the practice's
income after physician compensation. Some of these services result in operating
expenses that are directly reimbursed to the Company. Currently, Illinois is
the only state in which the Company is paid a flat fee because fees based on
percentages of revenues or income are not permissible. In certain states where
fees based on percentages of revenue or income are not permissible, the Company
charges a flat fee. In many instances, for the first five years of the Practice
Management Agreement the service fee is the greater of the fee determined by
the applicable formula or a fixed minimum amount. Payment of this minimum is,
in most instances, guaranteed by the physicians and the practice for five
years.     
 
  Services Provided. Pursuant to the various Practice Management Agreements,
the Company provides a range of services in consultation with the PHC Practice
including, among other things: (i) acting as manager and administrator of non-
medical services relating to the operation of the PHC Practice; (ii) billing
patients, insurance companies and other third-party payors and collecting the
fees for professional medical services and other services and products rendered
or sold by the PHC Practice; (iii) providing, as necessary or requested,
clerical, accounting, purchasing, payroll, legal, bookkeeping and computer
services and personnel, information management, preparation of certain tax
returns, printing, postage and duplication services and medical transcribing
services; (iv) supervising and maintaining custody of substantially all files
and records; (v) providing facilities for the PHC Practice; (vi) preparing, in
consultation with the Joint Policy Board and the PHC Practice, all capital
expenditure and operating budgets; (vii) ordering and purchasing inventory and
supplies as reasonably requested by the PHC Practice; and (viii) providing
financial and business assistance in the negotiation, establishment,
supervision and maintenance of contracts and relationships with managed care
and other payors.
 
  PHC Practice Responsibilities. Under the Practice Management Agreements, the
PHC Practices retain the responsibility for, among other things: (i) hiring and
compensating physician employees and other medical professionals; (ii) ensuring
that physicians and other medical professionals have the required licenses,
credentials, approvals and other certifications needed to perform their duties;
and (iii) complying with certain federal and state laws and regulations
applicable to the practice of medicine. In addition, the PHC Practices retain
exclusive control of all aspects of the practice of medicine and the delivery
of medical services.
   
  Term and Termination. The Practice Management Agreements are generally for
initial terms of 40 years. Practice Management Agreements may be terminated by
either party if the other party: (i) files a petition in bankruptcy or other
similar events occur or (ii) defaults in the performance of a material
financial obligation, which default continues for a specified term after
notice. In addition, certain Practice Management Agreements may also be
terminated by the Company if the PHC 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
does or reasonably would be expected to materially adversely affect the PHC
Practice. Certain PHC Practices may terminate their respective Practice
Management Agreements, subject to repurchase of their respective practice
assets, after the expiration of 66 months from the dates of such agreements,
for the original purchase price (including goodwill) with appropriate
adjustments.     
 
  Breach. The Company includes in all standard Practice Management Agreements
breach provisions that it believes to be stronger than those used by other
PPMs. The Company believes that these provisions discourage frivolous claims
that the Company has breached its obligations as a means of causing the
Practice Management
 
                                       48

Agreement to terminate early. In the event of a non-financial breach by either
party to the Practice Management Agreement, the non-breaching party typically
must, prior to termination, submit to an arbitrator the question of whether:
(i) a material breach has occurred and, if so, (ii) the amount of lost income,
exclusive of punitive or consequential damages (the "Lost Income Amount"),
suffered by the non-breaching party as the result of the breach. Typically, the
non-breaching party may terminate the Practice Management Agreement only if the
arbitrator determines a Lost Income Amount and the breaching party fails to pay
the Lost Income Amount within a specified time following determination of the
Lost Income Amount. Generally, upon termination of the Practice Management
Agreement, the PHC Practice is required to repurchase the assets used in the
operation of the PHC Practice, including assets such as goodwill.
   
  Physician Employment Agreements. The Practice Management Agreements require
the PHC Practice to enforce restrictive covenants contained in the employment
agreements (the "Physician Employment Agreements") between the PHC Practice and
the physicians associated with the PHC Practice. Typically, the Physician
Employment Agreements provide for an initial term of five years, require the
PHC Practice to compensate the PHC Physician on the basis negotiated between
the PHC Practice and the PHC Physician and require that the physician not
compete with the PHC Practice or the Company within a specified geographic area
during the term of the Physician Employment Agreement and for a period of up to
two years thereafter. In addition, certain Physician Employment Agreements
provide that if such physician's employment is terminated during the initial
five-year term for any reason other than the physician's death or disability or
the occurrence of certain events outside the physician's control, the physician
will be required to pay liquidated damages to the PHC Practice which the PHC
Practice in turn is obligated to remit to the Company. In most instances, the
Company is named as a third-party beneficiary of the Physician Employment
Agreements, with the right to enforce provisions of the Physician Employment
Agreements.     
   
  Owned Practices; Direct Employment. In states that permit such structures,
the Company directly employs physicians associated with the PHC Practice
pursuant to employment agreements (the "Direct Employment Agreements"). Florida
and Missouri are currently the only states in which PHC does business that
permit such employment arrangements. In such instances, each physician's annual
compensation is determined based generally on the net profits generated by the
physician. The physicians continue to control the medical aspects of the
practice and have input with respect to budgeting and strategic planning for
the PHC Practice. The Company has direct responsibility for all non-medical
aspects of the operation of the owned PHC Practices. Typically, the Company is
entitled to terminate the Direct Employment Agreement for cause as defined in
the relevant agreement. In addition, the Company may terminate the Direct
Employment Agreement if the physician materially breaches the Direct Employment
Agreement (as determined by an arbitrator) and either: (i) fails to pay the
Lost Income Amount suffered by PHC (as determined by an arbitrator) as a result
of the breach or (ii) continues to breach the Direct Employment Agreement,
despite having paid the Lost Income Amount.     
   
  Under a Direct Employment Agreement, the physician may voluntarily terminate
the physician's employment thereunder, at any time during the five-year term,
by delivering to the Company written notice of such intention not less than one
year prior to the effective date of termination. The physician may also
terminate the Direct Employment Agreement if: (i) the Company materially
breaches, and does not cure within the specified period, any of its financial
obligations under the Direct Employment Agreement or (ii) upon the occurrence
of an event of bankruptcy by PHC. Additionally, the physician, in conjunction
with the other physicians who sold the practice to PHC, may terminate the
Direct Employment Agreement if the Company materially breaches a non-financial
obligation (as determined by an arbitrator) and either: (a) fails to pay the
Lost Income Amount suffered by the physician (as determined by an arbitrator)
as a result of the breach or (b) continues to breach the Direct Employment
Agreement, despite having paid the Lost Income Amount. However, if the
physician terminates the physician's employment for any reason, other than upon
scheduled retirement, death or disability, or if the Company terminates the
physician's employment for cause within the first five years, then the
physician is required to pay to the Company liquidated damages. Two owned
practices in the Orlando area may be repurchased by their former physician
shareholders in the event all such physicians' employment agreements
simultaneously terminate as a result of a material breach by the Company. The
Company believes     
 
                                       49
<PAGE>
 
that these limitations on the physician's ability to terminate his or her
Direct Employment Agreement discourage frivolous claims that the Company has
breached its obligations thereunder as a means of causing the early termination
of a Direct Employment Agreement.
   
  Restrictive Covenants. The Direct Employment Agreements include several
restrictive covenants, including a covenant not to compete which prohibits the
physician from practicing the same type of medicine the physician practices for
the Company for two years following the date of cessation of employment by PHC
within a specified radius of the medical offices of the Company in which the
physician practiced. The Direct Employment Agreements also generally include
restrictions on the physician's right to solicit employees or patients of the
Company for a period of two years following the termination of physician's
employment with the Company. Certain physicians in the Orlando area have the
option of returning a portion of the acquisition consideration in lieu of
refraining from competition with the Company upon the expiration of their
Direct Employment Agreements. Finally, the Direct Employment Agreements
typically prohibit the disclosure of trade secrets and other confidential
information regarding the Company. The Practice Management Agreements require
the managed PHC Practices, and in many cases per next PHC, to enforce
restrictive covenants contained in the Physician Employment Agreements.     
COMPETITION
 
 
  The Company, PHC Physicians, PHC Networks and Affiliated Networks face
intense competition in all aspects of their businesses. The Company believes
that changes in governmental and private reimbursement policies, among other
factors, have resulted in increased competition among providers of medical
services and among networks for managed care contracts. The Company itself
faces intense competition to acquire or provide management services to
physician practices; to acquire or develop and operate ancillary health care
service facilities; and to provide management services, including contracting
services, to physician networks. A number of hospitals, clinics, health care
companies, HMOs, insurance companies and physician practice management
companies, both publicly and privately held, some of which have established
operating histories and greater resources that the Company, engage in
activities similar to those of the Company. There can be no assurance that the
Company will be able to compete effectively with its competitors, that
additional competitors will not enter the market, or that the Company will be
able to acquire or manage physician practices, acquire or develop ancillary
health care services, affiliate with or develop networks, or negotiate payor
contracts on terms beneficial to the Company. Any such failure could have a
material adverse effect on the Company's business, financial condition or
results of operations.
 
GOVERNMENT REGULATION
 
 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 Company believes that health care regulations
will continue to change. The Company expects to modify its agreements and
operations from time to time as the business and regulatory environment
changes. While the Company believes it will be able to structure its agreements
and operations in accordance with applicable law, there can be no assurance
that its business or such agreements or operations will not be successfully
challenged.
 
  Every state imposes licensing requirements on individual physicians and on
facilities and services operated by physicians. In addition, federal and state
laws regulate HMOs and other MCOs with which the Company, PHC Physicians, PHC
Practices, PHC Networks and Affiliated Networks may have contracts. Many states
require regulatory approval, including certificates of need, before
establishing or expanding certain types of health care facilities, offering
certain services or making expenditures in excess of statutory thresholds for
health care equipment, facilities or programs. In connection with the expansion
of existing operations and the entry into new markets, the Company, PHC
Physicians, PHC Practices, PHC Networks and Affiliated Networks may become
subject to compliance with additional regulation.
 
  The United States Congress and many state legislatures routinely consider
proposals to reform or modify the health care system, including measures that
would control health care spending, convert all or a portion of
 
                                       50
<PAGE>
 
government reimbursement programs to managed care arrangements, and balance the
federal budget by reducing spending for Medicare and state health programs.
These measures can affect a health care company's cost of doing business and
contractual relationships. For example, recent developments that affect the
Company's activities include: (i) federal legislation requiring a health plan
to continue coverage for individuals who are no longer eligible for group
health benefits and prohibiting the use of "pre-existing condition" exclusions
that limit the scope of coverage; (ii) a HCFA policy prohibiting restrictions
in Medicare HMOs or physicians recommending to patients other health plans and
treatment options; and (iii) regulations imposing restrictions on physician
incentive provisions in physician provider agreements. There can be no
assurance that such legislation, programs and other regulatory changes will not
have a material adverse effect on the Company's business, financial condition
or results of operations.
   
  The ability of the Company to operate profitably will depend in part upon the
ability of the Company, PHC Physicians, PHC Practices, PHC Networks and
Affiliated Networks obtaining and maintaining all necessary licenses,
certificates of need and other approvals and to operate in compliance with
applicable health care regulations.     
 
 Fee-Splitting; Corporate Practice of Medicine
 
  The laws of many states prohibit physicians from splitting fees with non-
physicians (or other physicians) and prohibit non-physician entities from
practicing medicine. These laws vary from state to state and are enforced by
the courts and by regulatory authorities with broad discretion. Although the
Company believes its operations are in material compliance with existing
applicable laws, the Company's business operations have not been the subject of
judicial or regulatory interpretation; thus, there can be no assurance that
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 existing operations or their 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.
   
  In particular, at least one Texas court has taken the position that control
by a management company over certain medical related business aspects of a
medical practice effectively is the prohibited corporate practice of medicine
by the management company. PHC has structured the management services agreement
related to the PHC Practice managed by PHC in Texas to comply with Texas law,
although no assurance can be provided that a party could not successfully
assert that management services agreement violates Texas law. Illinois courts
have indicated that employment of physicians by for profit corporations that
are not hospitals violates Illinois law related to the corporate practice of
medicine and that management fees based on a percentage of revenue or income
violate Illinois' prohibitions on fee-splitting. Accordingly, in Illinois PHC
does not employ physicians and the management fee charged under its practice
management agreement is a flat fee. The Florida Board of Medicine recently
entered a final order in a case titled In Re: The Petition For Declaratory
Statement of Magan L. Bakarania, M.D., supported by a prior Florida Board of
Medicine Order, stating that a management fee based on a specified percentage
of net income without direct relation to the services provided violates Florida
law related to fee-splitting. That case has been stayed pending appeal. The
Company cannot predict the ultimate outcome of this case. If the Florida Board
of Medicine order is affirmed by the Florida Court, the Company will seek to
restructure certain of the practice management agreements to which it is a
party in Florida, although there can be no assurance that the Company will be
successful in doing so. Three of the four agreements that the Company may seek
to restructure in Florida require the parties to negotiate in good faith to
reform the agreements to comply with applicable law and for the matter to be
referred to arbitration in the event that agreement with respect to
restructured terms cannot be reached.     
   
  Except as indicated in this Prospectus, the Company is not aware of
significant litigation related to the corporate practice of medicine or state
laws prohibiting or limiting fee-splitting that the Company anticipates will
materially affect its business. A determination in any state that the Company
is engaged in the corporate practice of medicine or any unlawful fee-splitting
arrangement could render any Practice Management     
 
                                       51
<PAGE>
 
   
Agreement between the Company and a PHC Practice located in such state
unenforceable or subject to modification, which could have a material adverse
effect on the Company. There can be no assurance that regulatory authorities
or other parties will not assert that the Company or a PHC Practice is engaged
in the corporate practice of medicine in such states or that the management
fees paid to the Company by the Practices constitute unlawful fee-splitting or
the corporate practice of medicine. If such a claim were asserted
successfully, the Company could be subject to civil and criminal penalties and
the Company or the PHC Practices could be required to restructure their
contractual arrangements. Such results or the inability of the Company or the
Practices to restructure their relationships to comply with such prohibitions
could have a material adverse effect on the Company's financial condition and
results of operations. See "Business--Government Regulation."     
 
 Changes in Payment for Medical Services
 
  The Company believes that trends in cost containment in the health care
industry will continue to result in a reduction from historical levels in per-
patient revenue for PHC 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
RBRVS has reduced payment rates for certain of the procedures historically
performed by PHC Physicians. There can be no assurance that any reduced
operating margins could be recouped by the Company through cost reductions,
increased volume, introduction of additional procedures or otherwise.
 
  Rates paid by nongovernmental insurers, including those that provide
Medicare supplemental insurance, are based on established physician,
ambulatory surgery center and hospital charges, and are generally higher than
Medicare payment rates. A change in the makeup of the patient mix of the
medical practices under Company management that results in a decrease in
patients covered by private insurance or a shift by private payors to RBRVS or
similar payment structures could adversely affect the Company's business,
financial condition or results of operations.
 
 Medicare and Medicaid Fraud and Abuse
   
  The Anti-Kickback Law prohibits the offer, payment, solicitation or receipt
of any form of remuneration in return for, or in order to induce: (i) the
referral of a person; (ii) the furnishing or arranging for the furnishing of
items or services reimbursable under Medicare or Medicaid programs; or (iii)
the purchase, lease or order or arranging or recommending purchasing, leasing
or ordering of any item or service reimbursable under Medicare or Medicaid.
Pursuant to the Anti-Kickback Law, the federal government has 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 Anti-Kickback
Law can result in exclusion from Medicare and Medicaid programs and civil and
criminal penalties. The PHC Practices collectively derive approximately 30% of
their revenues on a pro forma basis for the nine months ended September 30,
1997 from Medicare or Medicaid payments.     
   
  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 substantially
enlarging the field of physician-owned or physician-interested entities to
which the referral prohibitions apply. Stark II prohibits a physician from
referring Medicare or Medicaid patients to an entity providing "designated
health services" in which the physician has an ownership or investment
interest, or with which the physician has entered into a compensation
arrangement. The designated health services include, for example, prosthetic
devices, clinical laboratory services, radiology (such as ultrasound, MRI and
CT), home health, physical and occupational therapy, prescription drugs and
inpatient and outpatient hospital services. 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 referral violation and $100,000 for
participation in a "circumvention scheme." To the extent that the Company or
any PHC Practice is deemed to be subject to the prohibitions     
 
                                      52
<PAGE>
 
contained in Stark II, the Company believes its activities fall within the
permissible activities defined in Stark II, including, but not limited to, the
provision of in-office ancillary services.
 
  The Company believes that although it will receive service fees under its
agreements for management and administrative services, it is not generally in a
position to make or receive referrals of patients or services reimbursed under
the Medicare or Medicaid programs. Such service fees are intended by the
Company to be consistent with fair market value in arm's-length transactions
for the nature and amount of management services rendered and, therefore, would
not constitute unlawful remuneration under Anti-Kickback Law and regulations.
For these reasons, the Company does not believe that fees payable to it would
be viewed as remuneration for referring or influencing referrals of patients or
services covered by such programs as prohibited by statute. If the Company is
deemed to be in a position to make, influence or receive referrals from or to
physicians, the operations of the Company could be subject to scrutiny under
federal and state anti-kickback and anti-referral laws.
 
  In some jurisdictions that do not prohibit the corporate practice of
medicine, the Company owns practices and employs physicians. Thus, with respect
to such practices, the Company is a provider of services and would be capable
of receiving referrals from other physicians affiliated with PHC in those
markets. In these circumstances, PHC Practices either will not accept referrals
involving designated health services from other physicians affiliated with PHC
or will form group practices comprised of PHC Practices in that market.
 
  In addition, the Company also believes that the methods used to acquire the
assets of existing practices do not violate anti-kickback and anti-referral
laws and regulations. Specifically, the Company believes the consideration paid
by the Company to physicians to acquire assets in their practices is consistent
with fair market value in arm's-length transactions and not intended to induce
the referral of patients. Should this or any other Company practice be deemed
to constitute an arrangement designed to induce the referral of Medicare or
Medicaid patients, then such 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 or results of operations.
 
 Antitrust Issues
   
  Federal and state antitrust statutes prohibit conduct such as price fixing,
market allocation and other anti- competitive activities by groups of
competitors. The federal and state antitrust enforcement agencies have not
hesitated to bring civil and criminal enforcement actions against the joint
activities of physician organizations that allegedly violate the antitrust
laws. Collaboration regarding the pricing of services, market allocation and
certain other types of joint action, however, may be permissible in the context
of an integrated joint venture if those activities are ancillary to the
otherwise legitimate purposes of the joint venture. The federal antitrust
enforcement agencies, the FTC and the DOJ, have established "antitrust safety
zones" for physician networks that meet certain criteria. To the extent
physician providers in a network constitute less than 20% of the total
physicians in a specialty or sub-specialty which compete in the market and such
providers are either integrated in terms of sharing substantial financial risk
in their joint activities or are engaged in designing or implementing clinical
pathways with a view to improving medical outcomes, the network should fall
within one of the DOJ/FTC antitrust safety zones. To the extent that the
physician network is non-exclusive, i. e., physicians may provide services
outside the confines of the network, individually or as part of other groups or
networks, the federal antitrust enforcement authorities have indicated that
they will not challenge joint pricing or market allocation actions of an
integrated network of up to 30% of the physicians in a particular specialty or
sub-specialty. Conduct outside the antitrust safety zones is not necessarily
unlawful, but greater scrutiny will be given to the potential impact on overall
competition by regulatory authorities. State antitrust agencies may or may not
rely on antitrust analysis similar to that of the federal agencies.     
 
  While the federal antitrust enforcement authorities generally view
"substantial risk" as capitation or substantial withholding with respect to the
specific contracts or negotiations by the physician network, the
 
                                       53
<PAGE>
 
antitrust enforcement agencies have indicated that networks engaging in other
forms of financial risk-sharing may also be considered "integrated joint
ventures" for purposes of antitrust analysis. As yet, it is unclear whether
the agencies or the courts will consider arrangements in which providers have
an investment risk with actual capital contributed to the entity to be
sufficient financial integration. Nevertheless, to the extent that the
physician members will be at financial risk in terms of compensation under
proposed joint contracting under capitation or substantial withhold
arrangements, the agencies have indicated that these forms of risk-sharing are
sufficient to show the existence of an integrated joint venture. In addition,
demonstration of actual "clinical integration" by a physician network is
sufficient to avoid per se violations, according to the FTC and the DOJ.
   
  The two PHC Networks are non-exclusive networks that operate in the greater
Atlanta and greater Orlando metropolitan areas, respectively. As of December
31, 1997, except for one fee-for-service contract in Orlando, all of their
contracts are capitated or global risk contracts in which the providers share
substantial financial risk. The Atlanta PHC Network is comprised of primary
care physicians constituting less than 30% of the market practitioners of
family/general, internal and pediatric medicine. The Company believes that the
Atlanta PHC Network is within the antitrust safety zone for non-exclusive
networks. The Orlando PHC Network is a multi-specialty network including
physicians of many specialties. The Company believes that physician
representation in the Orlando PHC Network may exceed the non-exclusive safety
zone in several non-primary care specialties. The antitrust agencies
emphasize, however, that even if a physician network does not come within a
safety zone, it is not necessarily unlawful under the antitrust laws. For the
following reasons, the Company believes that its activities in the greater
Orlando metropolitan areas are pro-competitive and have the potential to
benefit purchasers of the physician services offered by its providers. First,
physician participation in the network is non-exclusive, and physician members
do in fact contract with other networks and health plans. Second, physician
members share inherent substantial financial risk by providing services for
global risk contracts and have the incentive to provide high quality, cost-
effective care in an environment of increasing managed care penetration.
Third, there are competing physician networks in the greater Orlando area.
Fourth, the specialties with respect to which the Orlando PHC Network may
exceed the safety zone are generally ones characterized by a limited number of
practices and physicians within the market.     
 
 Insurance Regulatory Risks
 
  An important element of the Company's business and strategy includes acting
as an agent for PHC Physicians, PHC Networks and Affiliated Networks to
negotiate with insurance companies, HMOs, employer self-funded plans, health
plans and other MCOs for the provision of health care services to the
subscribers or beneficiaries of the health plans operated by such parties.
Under some of these contracts, the Company receives capitation payments on
behalf of a network and reimburses participating physicians on a fee-for-
service basis. Under the laws of some states, this contracting arrangement
could be determined to involve an insurance risk. Therefore, to the extent the
Company is deemed to be in the business of insurance in a particular state,
the Company, PHC Physicians and PHC Networks could be subject to insurance
regulatory scrutiny; regulators could require restructuring of a specific
arrangement; and the Company's operations could be restricted, its expansion
limited, or certain of its operations prohibited.
   
 Medicare Developments     
 
  The recently adopted Balanced Budget Act of 1997 (the "BBA") enacted a
Medicare Plus/Medicare Choice Program for Medicare enrollees. The program
would broaden the coverage options available to Medicare recipients, would
authorize broader use of medical savings accounts, and would allow physicians
and patients to contract for health care services at rates beyond what is paid
by Medicare. Such changes potentially could increase the services utilized by
Medicare recipients. In addition, the BBA allows provider sponsored
organizations ("PSOs") to contract directly with Medicare, instead of
contracting through an HMO. If the PHC Practices, PHC Networks and Affiliated
Networks participate in such PSOs, they could increase the percentage of
Medicare-related business, which would also increase the exposure for losses
if Medicare revenues fall short of the cost of services actually utilized by
Medicare beneficiaries. If PHC does not participate in such PSOs, whether by
choice or because it does not obtain a required license to act as a PSO, PHC's
ability to participate
 
                                      54
<PAGE>
 
   
in Medicare programs could be limited. The BBA also amends the fraud and abuse
laws to require permanent exclusion from Medicare of anyone convicted of three
Medicare program-related crimes and to impose new civil monetary penalties to
anyone contracting with an excluded health care provider. These changes
increase the regulatory and other risks encountered by the Company. See "Risk
Factors--Direct Capitation; Risks Associated With Managed Care Contracts."
       
 Legislative Developments     
 
  In addition, proposed legislation regarding health care reform has been
introduced before many state legislatures. Any such reform at the federal or
state level could significantly alter patient-provider relationships. State
and federal agency rule-making addressing these issues is also expected. No
predictions can be made as to whether future health care reform legislation,
similar legislation or rule-making will be enacted or, if enacted, its effect
on the Company. Any federal or state legislation prohibiting investment
interests in, or contracting with, the Company by health care providers for
which there is no statutory exception would have a material adverse effect on
the Company's business, financial condition or results of operations.
 
EMPLOYEES
   
  As of December 31, 1997 the Company had approximately 477 employees, of
which approximately 52 were employed at the corporate or regional
administrative offices.     
   
PROPERTIES     
   
  The Company leases office space and practice facilities for the PHC
Practices. The Company also leases its headquarters under lease agreements for
approximately 8,849 square feet expiring in March 31, 1999 and approximately
6,500 square expiring in January, 2000.     
 
LEGAL PROCEEDINGS
 
  Certain PHC Physicians and PHC Practices are named defendants in malpractice
cases. By virtue of acquisition of certain of these practices by merger or
stock purchase transactions, certain Company subsidiaries are or are expected
to be defendants in these cases. Although there can be no assurance regarding
the eventual outcome of any particular malpractice case, the Company believes
that it has commercially reasonable malpractice insurance and limits in place
with respect to these subsidiaries. PHC, the parent company, is not a party to
any claims, suits or complaints relating to services and products provided by
the Company, the PHC Physicians or PHC Practices or the networks. There can be
no assurance, however, that such claims will not be asserted against the
Company in the future or that the Company will not become subject to certain
claims as the result of successor liability in connection with the acquisition
of any practice or network.
 
CORPORATE LIABILITY AND INSURANCE
 
  The provision of medical services entails an inherent risk of professional
malpractice and other similar claims. The Company does not influence or
control the practice of medicine by physicians or the compliance with certain
regulatory and other requirements directly applicable to physicians and
physician groups. There can be no assurance that claims, suits or complaints
relating to services and products provided by physicians or networks will not
be asserted against the Company in the future. The Company currently maintains
insurance coverage that it believes will be adequate both as to risks and
amounts. Such insurance currently extends to professional liability claims
that may be asserted against PHC Physicians or against employees of the
Company that work locally at the PHC Practices or at the networks. In
addition, pursuant to the network service agreements and Practice Management
Agreements, the physicians and networks are required to maintain comprehensive
professional liability insurance. The availability and cost of such insurance
has been affected by various factors, many of which are beyond the control of
the Company, the physicians and the networks. The cost of such insurance to
the Company, PHC Physicians and PHC Networks may have a material adverse
effect on the Company's business, financial condition or results of
operations. In addition, successful malpractice or other claims asserted
against PHC Physicians, PHC Networks or the Company that exceed applicable
policy limits could have a material adverse effect on the Company's business,
financial condition or results of operations.

BOARD COMMITTEES
 
 
  The Company maintains an Executive Committee, a Compensation Committee, an
Audit Committee and a Compliance Committee. These committees have the following
functions:
 
  The Executive Committee has broad authority to take certain actions on behalf
of the Board of Directors between meetings of the Board of Directors. This
committee currently consists of Ms. Garvin, Mr. Rodgers, Dr. Ribaudo, Mr.
Anantharaman and Mr. Cronin.
 
  The Compensation Committee reviews and approves the salaries, bonuses and
other compensation and benefits of executive officers and advises management
regarding benefits and other terms and conditions of compensation. Ms. Garvin,
Mr. Rodgers and Mr. Cronin currently serve on this committee.
 
  The Audit Committee makes recommendations to the Board of Directors with
respect to the appointment of independent auditors, reviews significant audit
and accounting policies and practices, meets with the Company's independent
public accountants concerning, among other things, the scope of audits and
reports, and reviews the performance of the overall accounting and financial
controls of the Company. This committee currently consists of Mr. Anantharaman
and Mr. Cronin.
   
  The Compliance Committee establishes and communicates to the Company's
officers, employees, agents and the PHC Practices and PHC Physicians certain
guidelines with regard to compliance with the Company's mission, legal and
regulatory matters (including Medicare/Medicaid compliance) and other Company
policies. The Compliance Committee consults with and advises the Board of

regarding operational compliance with the established guidelines and procedures
for reporting and investigating instances of noncompliance. This committee has
three voting members, Ms. Garvin, Mr. Rodgers and Dr. DiStefano. Advisory
members include Ms. Moore, Stephen R. Mintz, M.D. and Daniel M. Epstein, M.D.
    
  The Company intends to establish a committee of non-employee directors to
administer the Company's stock option plans on consummation of the Offering.
 
BOARD OF DIRECTOR COMPENSATION
   
  The Company's Bylaws provide that Directors of the Company may be paid their
expenses of attending Board of Director and Committee meetings and may also be
paid a fixed sum for attendance at such meetings or a retainer for service as a
director. Currently, directors are only reimbursed for expenses and do not
receive any compensation for serving as a director or attending meetings.
Directors are also eligible for discretionary option grants under the 1995
Stock Option Plan. On March 7, 1996, Carl Schramm and Jack Keane (who served on
the Board of Directors from March 1996 to June 1997) were granted options to
purchase 300,000 shares of the Common Stock, at an exercise price of $3.18 per
share, for services rendered and to be rendered to the Company. Of each of
their grants, 23,550 options vested immediately, 17,663 vested on March 7, 1997
and 17,662 will vest on each of March 7, 1998, March 7, 1999 and March 7, 2000.
No other compensation was received by any director in 1997 for his or her
service as a director.     
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
  Delaware law authorizes corporations to limit or eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach of a director's fiduciary duty of care. Delaware law enables
corporations to limit available relief to equitable remedies such as injunction
or rescission. The Certificate of Incorporation limits the liability of
directors of the Company to the Company or its stockholders to the fullest
extent permitted by Delaware law. Specifically, directors of the Company will
not personally be liable for monetary damages for breach of a director's
fiduciary duty as a director, except for liability for unlawful payments of
dividends or unlawful stock repurchases or redemptions as provided in the DGCL.
 
                                       59
<PAGE>
 
  The inclusion of this provision in the Certificate of Incorporation may have
the effect of reducing the likelihood of derivative litigation against
directors and may discourage or deter stockholders or management from bringing
a lawsuit against directors for breach of their duty of care, even though such
an action, if successful, might otherwise have benefitted the Company and its
stockholders. The Company's Bylaws provide indemnification to the Company's
officers and directors and certain other persons with respect to certain
matters.
 
1995 STOCK OPTION PLAN
   
  In October, 1995, the Board of Directors adopted, and the stockholders of the
Company approved, the 1995 Stock Option Plan. The purpose of the 1995 Stock
Option Plan is to provide directors, key employees and certain advisors with
additional incentives by increasing their proprietary interest in the Company.
The aggregate amount of Common Stock with respect to which options may be
granted may not exceed 2,198,000 shares prior to consummation of the Offering
and 3,140,000 shares thereafter.     
 
  The 1995 Stock Option 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 nonqualified stock options (collectively "Awards").
The 1995 Stock Option Plan will be administered by a committee of non-employee
director upon consummation of the Offering. The committee will have, subject to
the terms of the 1995 Stock Option Plan, the sole authority to grant Awards
under the 1995 Stock Option Plan, to construe and interpret the 1995 Stock
Option Plan, and to make all other determinations and take any and all actions
necessary or advisable for the administration of the 1995 Stock Option Plan.
 
  All of the Company's key employees, non-employee directors and advisors are
eligible to receive Awards under the 1995 Stock Option 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 become
exercisable in installments pursuant to a vesting schedule designated by the
Committee. In the discretion of the Committee, option agreements may provide
that options will become immediately exercisable in the event of a "change in
control" (as defined in the 1995 Stock Option Plan) of the Company. A "change
of control" is deemed to have occurred if the Company is a party to merger,
share exchange or other business combination pursuant to which the Company does
not remain independent or if substantially all of the assets of the Company are
sold or otherwise transferred. 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 voting capital stock of the
Company).
 
  The exercise price for ISOs granted under the 1995 Stock Option Plan may be
no less than the fair market value of the Common Stock on the date of grant (or
110% in the case of ISOs granted to employees owning more than 10% of the
voting capital stock).
 
401(K) PLAN
 
  Effective January 1996, the Company adopted the Physician Health Corporation
401(k) Plan (the "Savings Plan"). The Savings Plan is intended to provide PHC
employees with retirement benefits. The Savings Plan is intended to constitute
a qualified cash or deferred profit sharing plan within the meaning of Sections
401(a) and 401(k) of the Internal Revenue Code of 1986.
 
  All employees of the Company are eligible to participate in the Savings Plan
who have reached the age of 21 years and have completed six months of service
with the Company as of any January 1 or July 1. The Savings Plan is
administered by the Board of Directors, which has full power to administer and
interpret the Savings Plan. The assets of the Savings Plan are held by a trust
administered by a trustee pursuant to a trust agreement.
 
  Eligible employees may contribute a portion of their annual compensation, in
the form of payroll deductions, up to the legal maximum established by the
Internal Revenue Service for each plan year. The
 
                                       60
<PAGE>
 
Company may make profit sharing contributions, employee matching contributions
and other additional employer contributions of any amount at the Company's
sole discretion. Employee contributions are fully vested immediately. Company
contributions are vested over the first five years of employment. No Company
contributions have been made.

EMPLOYMENT AGREEMENTS; TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL
ARRANGEMENTS
   
  The Company is party to Employment Agreements (collectively, the "Employment
Agreements") with each of Ms. Garvin, Mr. Rodgers and Dr. Ribaudo. Each of the
Employment Agreements provides for a specified base salary subject to annual
adjustment by the Board of Directors or the Compensation Committee of the
Board of Directors. Currently, the salaries payable under the Employment
Agreements are $210,000 for Ms. Garvin (subject to increase to $270,000 upon
consummation of the Offering), $205,000 for Mr. Rodgers (subject to increase
to $260,000 upon consummation of the Offering and $200,000 for Dr. Ribaudo
(subject to increase upon consummation of the Offering). In the event that the
Employment Agreements are terminated by the Company for cause (as defined in
the Employment Agreements) or by the employee without cause, the employee is
not entitled to severance pay. In the event that the Company terminates the
employee's employment by the Company without cause, the employee is entitled
to severance pay equal to 12 months' salary.     
       
  If the employee's employment with the Company is terminated following a
change in control of the Company (as defined in the Employment Agreement): (i)
by the Company without cause or (ii) by the employee because she or he is
required to relocate, her or his salary is reduced from the amount in effect
immediately prior to the change in control, her or his title is reduced or her
or his duties and responsibilities are substantially diminished, then the
employee is entitled to severance pay equal to 36 months' salary.
   
  The Company and its Founders are parties to a Restated and Amended
Stockholder Agreement dated November 1, 1996, as amended in February 1997 (the
"Stockholder Agreement"). For each Founder 94,200 shares of Common Stock
("Founder Stock") are subject to the Stockholder Agreement. Pursuant to the
Stockholder Agreement, 41,213 shares of Founder Stock have vested, and
17,662.50 shares of the remaining shares will vest on each of January 1, 1998,
January 1, 1999 and January 1, 2000 if the Founder remains a full-time
employee of the Company until the applicable vesting date; provided, however,
that, with respect to 11,775 shares that would otherwise vest on January 1,
2000, the Company shall have met certain performance criteria by December 31,
1998. The Stockholder Agreement provides that all shares of Founder Stock will
vest immediately upon the merger, consolidation or sale of the Company with or
to any other entity if the Company is not the surviving entity, or upon the
sale of substantially all of the Company's assets.     
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  In 1997, the Board of Directors established a compensation committee
composed of Ms. Garvin and Messrs. Cronin and Rodgers. Prior to establishment
of the Compensation Committee, compensation for the Company's
 
                                      62
<PAGE>
 
   
executive officers was determined by the entire Board of Directors. Mr. Rodgers
participated in deliberations of the Board of Directors concerning executive
officer compensation prior to his election to the Board of Directors in June
1997.     
   
  On May 1, 1997, Ms. Garvin loaned the principal amount of $250,000 to the
Company. On May 1, 1997, Thomas M. Rodgers, Jr. Defined Benefit Keogh Plan
11/15/82 also loaned the principal amount of $50,000 to the Company. Both notes
bear simple interest on principal at 12.0% per year, require payment of a 1%
origination fee upon retirement of the Notes and provide for payment on demand
after the earlier of closing of a venture capital investment by Weston Presidio
Capital or May 1, 1998. Such venture capital investment closed on June 16, 1997
but neither Ms. Garvin nor Mr. Rodgers has demanded payment of these notes.
       
  The Company and its Founders, including Ms. Garvin, are parties to a Restated
and Amended Stockholder Agreement dated November 1, 1996, as amended in
February 1997 (the "Stockholder Agreement"). For each Founder 94,200 shares of
Common Stock ("Founder Stock") are subject to the Stockholder Agreement.
Pursuant to the Stockholder Agreement, 41,213 shares of Founder Stock have
vested, and 17,662.50 shares of the remaining shares will vest on each of
January 1, 1998, January 1, 1999 and January 1, 2000 if the Founder remains a
full-time employee of the Company until the applicable vesting date; provided,
however, that, with respect to 11,775 shares that would otherwise vest on
January 1, 2000, the Company shall have met certain performance criteria by
December 31, 1998. The Stockholder Agreement provides that all shares of
Founder Stock will vest immediately upon the merger, consolidation or sale of
the Company with or to any other entity if the Company is not the surviving
entity, or upon the sale of substantially all of the Company's assets.     
   
  Prior to becoming an employee in January 1997, Mr. Rodgers provided financial
consulting services to the Company. His compensation for these services was to
be primarily based on the Company's successful capital raising activities. In
June, 1997, Mr. Rodgers and the Company agreed to terminate this compensation
agreement and to settle all fees earned and expected to be earned for his
financial consulting services. Accordingly, Mr. Rodgers was granted an option
to purchase 7,648 shares of Prime Common Stock at $0.011 per share, an option
to purchase 37,500 shares of Prime Common Stock at an exercise price of $1.10
per share and an option to purchase 76,302 shares of Common Stock (vesting over
four years) at $12.74 per share. In addition, the settlement provided for the
full vesting of previously granted options to purchase 350,000 shares of Prime
Common Stock at $1.15 per share. Mr. Rodgers was also granted piggyback
registration rights with respect to the 350,000 shares and 76,302 shares. Upon
consummation of the Offering and giving effect to the reverse Stock Split, each
share of Prime Common Stock will convert into .314 share of Common Stock. As
cash consideration, Mr. Rodgers has received $810,000. As provided in his
original consulting agreement, the Company has agreed to pay Mr. Rodgers an
amount equal to the difference between the state and federal taxes he will owe
resulting from the exercise of the option to purchase 350,000 shares and the
state and federal taxes that he would have paid had the options received
incentive stock option treatment.     
   
  Also as part of this settlement, the Company loaned Mr. Rodgers approximately
$442,000 to exercise his options for 37,500 and 350,000 shares of Prime Common
Stock. The loans are non-recourse but are secured by the stock purchased with
the proceeds of the loan. The loans bear simple interest at a rate of 6.80% per
year. The notes are payable at the earlier of the sale of such stock or June
16, 2007. Interest on these notes will be reimbursed to Mr. Rodgers by the
Company (and grossed up based on applicable tax rates to Mr. Rodgers).     
   
  Mr. Cronin is a General Partner of Weston Presidio Capital, which manages
venture capital funds including Weston Presidio Capital II, L.P. ("Weston II").
On June 16, 1997, the Company entered into a Series B Securities Purchase
Agreement among the Company, Weston II, Asset Management plc, on behalf of
Rowan Nominees Limited ("Mercury") Mercury, NatWest Ventures Investments Ltd
("NatWest") and certain other investors. Pursuant to the Series B Securities
Purchase Agreement, in June 1997 the Company sold 2,447,772 shares of Series B
Stock for an aggregate purchase price of $9,791,088, of which 1,529,958 shares
were purchased by Weston II for an aggregate purchase price of $6,119,832,
305,938 shares were purchased by Mercury for an aggregate purchase price of
$1,223,752 and 152,969 shares were purchased by NatWest for an aggregate
purchase price of $611,876. Upon consummation of the Offering, each share of
Series B Voting Preferred Stock will be converted into .314 share of Common
Stock and the holder of such converted stock may     
 
                                       63

<PAGE>
 
   
be entitled to an extraordinary dividend per share equal to the amount by
which $22.29 exceeds the initial offering price per share of Common Stock. See
"Description of Capital Stock-Authorized Capital Stock." As part of that
transaction, Weston II was granted a warrant to purchase 160,135 shares of
Common Stock for an aggregate purchase price of $5,099.86, Mercury was granted
a warrant to purchase 32,021 shares of Common Stock for an aggregate purchase
price of $1019.79 and NatWest was granted a warrant to purchase 16,010 shares
of Common Stock for an aggregate purchase price of $509.90. All such warrants
have an exercise price of $0.03 per share. The proceeds of the Series B
Securities Purchase Agreement were used to fund the acquisition of certain PHC
Practices. Pursuant to an Equity Call Agreement entered into on June 16, 1997
(the "Equity Call Agreement") the Company has the ability to require the
holder of its Series B Preferred Stock to purchase shares of Common Stock at
$12.74 per share sufficient to retire a $6.2 million note payable by the
Company on April 1, 1998 in connection with the purchase of the Arlington
Cancer Center. Weston II, Mercury and NatWest are obligated to purchase, at
the request of the Company, 170,336, 34,067 and 17,033 shares of Common Stock,
respectively, pursuant to such arrangement. The Series B Securities Purchase
Agreement and the Equity Call Agreement have been amended to include
subsequent purchasers of Series B Preferred Stock. Upon such further
investment, Weston II, Mercury and NatWest would receive additional warrants
to purchase 17,033, 3,406 and 1,703 shares of Common Stock, respectively, at
an exercise price of $0.03 per share. In connection with the Series B
Securities Purchase Agreement, Weston II, Mercury, NatWest, EGL Holdings, Ms.
Garvin, Mr. Rodgers, Mr. Holt, Ms. Moore, Dr. Fagin, Mr. Scott, Dr. Ribaudo
and certain other investors entered into a Second Amended and Restated
Stockholders' Agreement, which granted Weston II, Mercury, NatWest and EGL
Holdings co-sale rights and certain other voting agreements all of which
expire upon consummation of the Offering. The Second Amended and Restated
Stockholders' Agreement was amended on October 27, 1997 to include Paribas
Principal, Inc. and Paribas Capital Funding L.L.C. The Second Amended and
Restated Stockholders' Agreement will terminate upon consummation of the
Offering.     
   
  In September 1997, the Company borrowed $3.0 million from Southwest Bank
(the "Southwest Loan") to help finance the acquisition of Southern
Dependacare. The Company executed a demand note in connection with this loan,
payment of which was guaranteed by certain holders of the Series B Preferred
Stock (including without limitation Weston II, Mercury and NatWest). In
exchange for the guaranty, the Company issued to the guarantors warrants to
purchase a total of 26,840 shares of Common Stock at an exercise price of
$12.74 per share. The Southwest Loan was paid in full in November 1997 using
proceeds from the Banque Paribas financing.     
       
                             CERTAIN TRANSACTIONS
          
  Mr. Anantharaman is an executive officer and an owner of EGL Holdings. EGL
Holdings from time to time represents Mercury and NatWest, in venture capital
investments. Pursuant to a Stock and Warrant Purchase Agreement dated December
29, 1995, a group of investors led by EGL Holdings, including Mercury and
NatWest, made a $3.0 million investment in the Company through the Class A
Stock. In connection with the Stock and Warrant Purchase Agreement, the
Company issued 95,700 shares of Series 1 Class A Stock and contingent warrants
to purchase up to 95,700 shares of Series 1 Class A Stock to NatWest for an
aggregate purchase price of $1,435,500 and 95,700 shares of Series 2 Class A
Stock and contingent warrants to purchase up to 95,700 shares of Class A Stock
to Mercury Asset for an aggregate purchase price of $1,435,500. The contingent
warrants are exercisable upon a redemption of the Class A Stock by the Company
at an exercise price of $15.00 per share. The Company also issued to EGL
Holdings warrants to purchase up to 59,660 shares of Common Stock at an
exercise price of $.03 per share. In connection with this transaction, Ms.
Garvin, Dr. Fagin, Ms. Moore, Mr. Scott and Mr. Holt each executed a Non-
Competition and Non-Disclosure Agreement. The Company also agreed to engage
EGL Holdings to act as an advisor to the Company, at a fee of $6,000 per month
plus reimbursement of reasonable expenses, from January 1, 1996 until such
time as there are no longer any shares of the Company's Class A Stock
outstanding. The Company paid EGL Holdings approximately $73,000 during 1997
pursuant to this agreement. Upon consummation of the Offering and after giving
effect to the Reverse Split, each share of Class A Stock will be converted
into 3.01 shares of Common Stock. Mercury and NatWest are also parties to the
Series B Securities Purchase Agreement and the Equity Call Agreement.

  Dr. DiStefano is the managing partner of the Arlington Cancer Center.
Pursuant to an Asset Purchase and Contribution Agreement, dated June 16, 1997,
among the Company, the Arlington Cancer Center, the individual physicians
named therein (the "Arlington Physicians"), each of the Arlington Physicians
wholly-owned professional associations (the "Physician Professional
Associations") and MHOA Texas I, L.L.C., a subsidiary of the Company ("MHOA
Texas"), (the "Arlington Purchase Agreement"), the Arlington Cancer Center
sold substantially all of its assets to MHOA Texas for an aggregate purchase
price of $24.5 million, of which $11.8 million was paid in cash, $6.2 million
was paid in the form of a promissory note and $6.5 million was paid in the
form of a subordinated promissory note. In addition to the cash consideration,
the Physician Professional Associations received in the aggregate a 20.0%
interest in MHOA Texas. The aggregate 20.0% interest in MHOA Texas held by the
Physician Professional Associations may be exchanged for a total of 480,420
shares of Common Stock under certain circumstances pursuant to an exchange
rights agreement. The $6.2 million promissory note is non-interest bearing and
the entire principal balance is due on April 1, 1998. The subordinated
promissory note is non-interest bearing and is payable in four annual
installments beginning on April 1, 1999. Through his interest in the Arlington
Cancer Center, Dr. DiStefano has a 4.6% interest in MHOA Texas. Pursuant to
the Arlington Purchase Agreement, the Company also agreed to appoint
Dr. DiStefano to the Board of Directors of the Company. The Company, MHOA
Texas and the Arlington Cancer Center have entered into a management services
agreement with a term of 40 years pursuant to which MHOA Texas provides
physician practice management services to the Arlington Cancer Center for an
annual fee equal 12.0% of the Arlington Cancer Center's net practice revenue,
an additional 55.0% of the practice pre-tax income and the reimbursement of
certain interest and depreciation expenses. Physicians salaries and operating
expenses, including the reimbursable interest and depreciation expenses, are
paid before PHC's management fees are paid. The annual management fee accrues
each year whether or not there are sufficient practice revenues remaining that
year after payment of physician salaries and operational expenses.     
   
  In connection with the purchase of the Arlington Cancer Center assets, MHOA
Texas obtained $8.0 million term debt financing from DVI Financial Services,
Inc. through six separate loans, and $5.0 million revolving credit facility
from DVI Business Credit Corporation. The interest rate on the DVI Financial
Services, Inc. loans is 12.25% simple interest and the loans mature in August,
2002. The interest rate on the DVI Business Credit Corporation facility loan
is 2.5% above the variable rate set by Bank of America, NT&SA in San
Francisco, California and that facility may be terminated by the Company in
August, 1999. The Company agreed to act as guarantor in connection with the
debt financing. The Company issued to DVI Financial Services, Inc. warrants to
purchase up to 15,700 shares of Common Stock at an exercise price of $15.92
per share in consideration of making the loans.     
   
  In November 1996, Metropolitan Plastic, of which Dr. Ribaudo is the sole
shareholder, sold substantially all of its assets to the Company in exchange
for: (i) $500,000 payable in the form of a convertible promissory note (the
"Convertible Note"); (ii) 125,000 shares of Prime Common Stock; and (iii) the
assumption of certain liabilities in the amount of $20,718. The promissory
note bore interest at a rate of 5.0% per annum and would have mature on
November 26, 1999. Prior to maturity but after an initial public offering by
the Company, the promissory note was convertible in $100,000 increments by the
holder into Common Stock at a price of $4.00 per share. The Company reimbursed
Dr. Ribaudo for approximately $32,000 in legal fees incurred by him in
connection with this transaction. Contemporaneously with the purchase of
substantially all of the assets of Metropolitan Plastic: (a) the Company
entered into an Undertaking Agreement with Dr. Ribaudo and Metropolitan
Plastic (the "Ribaudo Undertaking Agreement"); and (b) Metropolitan Plastic
entered into a Practice Management Agreement with the Company with a term of
40 years. Pursuant to the Practice Management Agreement, the Company agreed to
provide practice management and development services to Metropolitan Plastic
for an annual base fee of $100,000 plus 20.0% of the net practice revenue of
the practice less its operating expenses in excess of $550,000 per year during
the first five years of the agreement, and 20.0% of the net practice revenue
of the practice less operational expenses during the remainder of the
agreement. In addition, Metropolitan Plastic agreed to pay to the Company a
development fee equal to 7.0% of the revenues generated by new practice
physicians recruited by the Company.     
 
                                      65

  Pursuant to the Ribaudo Undertaking Agreement the Company agreed to: (i)
employ Dr. Ribaudo on an at-will basis at an annual salary of $100,000 and to
increase his salary to $250,000 after the completion of an initial public
offering of Common Stock; (ii) appoint Dr. Ribaudo to the Board of Directors
of the Company; (iii) sell to him 31,400 shares of Common Stock at $12.74 per
share (which he has purchased); and (iv) provide him with a quarterly "draw"
as described below. The Ribaudo Undertaking Agreement also granted Dr.
Ribaudo: (a) an option to purchase 94,200 shares of Common Stock at $12.74 per
share, vesting over a period of four years (with accelerated vesting if PHC
completes a single sale of securities resulting in a change of control of the
Company); and (b) options to purchase 47,100 shares of Common Stock at $12.74
per share, 31,400 of which are vested, with options to purchase 7,850 shares
of Common Stock vesting on each of December 31, 1998 and 1999. The Ribaudo
Undertaking Agreement originally provided that Dr. Ribaudo would be paid
$600,000 upon the Company's achievement of $1.5 million in projected annual
practice revenue from Missouri and central and southern Illinois. The parties
revised the geographic area subject to this target several times, ultimately
determining that Dr. Ribaudo should receive credit toward meeting this target
from all practice acquisitions in which he played a substantial role. As a
result of several PHC Practice acquisitions in mid-November, it was determined
that the revenue goals were met and Dr. Ribaudo was paid $600,000.     
   
  Under the "draw" arrangement, for any month in which Dr. Ribaudo received
less than $29,167 in revenue from his medical practice, he was advanced the
deficiency from the Company. The advance was subject to offset, less his
"earned draw", against amounts due to Dr. Ribaudo or Metropolitan Plastic. The
earned draw was calculated as a percentage, ranging from 0.5% to 2.5%
depending on his role, of the initial annual management fee payable by PHC
Practices in which Dr. Ribaudo had a substantial role in the acquisition. Dr.
Ribaudo was paid approximately $248,000 pursuant to this arrangement for the
twelve months ended December 31, 1997. For that same period, his earned draw
was approximately $   , reducing to approximately $    the amount to be repaid
to the Company through offsets.     
   
  Effective December 31, 1997, Dr. Ribaudo and Company entered into a
settlement agreement (the "Settlement Agreement") pursuant to which the "draw"
arrangement was terminated, Dr. Ribaudo forgave amounts owed by PHC under the
Convertible Note and PHC forgave the approximately $    owed to PHC by Ribaudo
under the draw arrangement, as well a $30,000 loan made by PHC to Dr. Ribaudo.
Under the Settlement Agreement the Company also granted Dr. Ribaudo options to
purchase 47,100 shares of Common Stock at an exercise price of $12.74 per
share. Further, the Company and Dr. Ribaudo agreed that the Practice
Management Agreement between Metropolitan Plastic and the Company would
terminate on the earlier to occur of June 30, 1998 and the date that Dr.
Ribaudo ceases to practice medicine. The Company agreed to reimburse Dr.
Ribaudo for: (i) reasonable moving expenses related to the relocation of his
residence from St. Louis to Atlanta; (ii) malpractice premium expense; (iii)
legal fees up to $5,000 incurred by him in connection with negotiation of the
Settlement Agreement; (iv) rental expense for an apartment in Atlanta for a
period of up to 12 months; and (v) annual continuing medical education expense

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 incur any further indebtedness to, or make any loans to,
any of its executive officers, directors or other affiliates.

                         DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED CAPITAL STOCK
   
  Upon completion of the Offering, the Company's authorized capital stock will
consist of 100,000,000 shares of Voting Common Stock, par value $0.0025 per
share (the "Common Stock"), 40,000,000 shares of Non-Voting Common Stock, par
value $0.0025 per share (the "Non-Voting Common Stock") and 18,000,000 shares
of Preferred Stock, par value $0.01 per share (the "Preferred Stock"). At
December 31, 1997 (without giving effect to the Reverse Split) there were:
(i) 500,000 shares of Class A Stock authorized and 200,000 shares of Class A
Stock outstanding; (ii) 9,000,000 shares of Series B Voting Preferred Stock
authorized and 3,460,362 shares of Series B Voting Preferred Stock
outstanding; (iii) 6,000,000 shares of Series B Non-Voting Preferred Stock
authorized and 917,814 shares of Series B Non-Voting Preferred Stock
outstanding; (iv) 20,000,000 shares of Prime Common Stock authorized and
6,358,140 shares of Prime Common Stock outstanding; (v) 40,000,000 shares of
Non-Voting Common Stock authorized, none of which are outstanding; and (vi)
100,000,000 shares of Common Stock authorized and 8,604,239 shares of Common
Stock outstanding. All of the currently outstanding shares of Common Stock,
Non-Voting Common Stock, Prime Common Stock, Class A Stock, Series B Voting
Preferred Stock and Series B Non-Voting Preferred Stock are validly issued,
fully paid and nonassessable under the Delaware General Corporation Law (the
"DGCL"). As of December 31, 1997, the Company had approximately 202
stockholders of record.     
   
  Upon the consummation of the Offering: (i) each share of Class A Stock will
convert into 3.01 shares of Common Stock; (ii) each share of Prime Common
Stock and Series B Voting Preferred Stock will convert into 0.314 of a share
of Common Stock; and (iii) each share of Series B Non-Voting Preferred Stock
will convert into 0.314 of a share of Non-Voting Common Stock. If the initial
Offering price is less than $22.29 per share of Common Stock, the Company will
be required to accrue an extraordinary dividend payable with respect to each
share of Series B Preferred Stock equal to $22.29 per share less the initial
Offering price per share of Common Stock. This extraordinary dividend would be
payable one year after the consummation of the Offering and could be paid
either in cash or in Common Stock. The requirement to pay such dividend will
be terminated if, at any time during the one-year period after consummation of
the Offering, the average price of the Common Stock on the Nasdaq National
Market is greater than $22.29 per share for any 20 consecutive trading days.
       
  The following summary describes the capital stock of the Company to be
authorized on completion of the Offering. This summary describes the material
elements of the Company's Fourth Amended and Restated Certificate of
Incorporation (the "Certificate") as it relates to the Company's capital stock
but is subject to, and qualified in its entirety by, the provisions of the
Certificate and by the provisions of applicable law, including the DGCL.     
 
COMMON STOCK AND NON-VOTING COMMON STOCK
 
  Voting Rights
 
  Each holder of Common Stock is entitled to one vote per share in the
election of directors and for all other purposes. The holders of Non-Voting
Common Stock do not have voting rights unless otherwise required by law or by
the Certificate. Except as otherwise provided, there are no cumulative voting
or preemptive rights applicable to any shares of the Company's stock.
 
  Dividends and Other Distributions
 
  All shares of Common Stock and Non-Voting Common Stock are entitled to
participate pro rata in distributions and in such dividends as may be declared
by the Board of Directors of the Company out of funds legally available
therefor, subject to any preferential dividend rights of outstanding shares of
Preferred Stock.
 
                                      67
<PAGE>
 
  Subject to the prior rights of creditors, all shares of Common Stock and Non-
Voting Common Stock are entitled in the event of any voluntary or involuntary
liquidation, dissolution or winding up of the Company, or upon the sale of
substantially all of the assets of the Company or upon a merger of the Company
in which the Company is not the surviving entity (each a "Distribution Event")
to participate ratably, share and share alike, in the distribution of all the
remaining assets of the Company after distribution in full of preferential
amounts, if any, to be distributed to holders of Preferred Stock.
 
  Conversion Rights
   
  At the option of Regulated Stockholders (as defined below), each share of
Common Stock and Non-Voting Common Stock is convertible into one share of Non-
Voting Common Stock or Common Stock, as the case may be, at any time and from
time to time, upon delivery to the Company of a certificate signed on behalf of
the holder seeking such conversion. The Company will not convert, redeem,
purchase, acquire or take any other action affecting the outstanding shares of
Common Stock or Non-Voting Common Stock if such action would, with respect to:
(i) any legal entity that is subject to Regulation Y of the Board of Governors
of the Federal Reserve System (12 C.F.R. Part 225) (a "Regulated Stockholder")
or (ii) any affiliate of any such Regulated Stockholder, increase the
percentage of outstanding voting securities owned or controlled by such
Regulated Stockholder to more than 4.9% or increase the percentage of the total
equity or the value of all of the capital stock of the Company owned or
controlled by such Regulated Stockholder to more than 24.9% unless the Company
gives written notice of such action to each Regulated Stockholder or affiliate.
The terms of the Common Stock and Non-Voting Common Stock are the same with the
exception of voting rights. The Company may not redeem or take any other action
affecting outstanding shares of Common Stock or Non-Voting Common Stock, if
after giving effect to such redemption a Regulated Stockholder would own more
than 4.9% of any class of voting securities of the Company, 24.9% of the total
equity of the Company or more than 24.9% of the total capital stock of the
Company. The rights, preferences and privileges of holders of Common Stock are
subject to, and may be adversely affected by, the rights of any shares of
Preferred Stock that may be issued by the Company from time to time.     
 
PREFERRED STOCK
 
  The Preferred Stock may be issued from time to time by the Board of Directors
as shares of one or more series. Subject to the provisions of the 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, exchange 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 the Preferred Stock, in each case without any further action or vote
by the holders of Common Stock.
 
  Although the Company has no present intention to issue shares of Preferred
Stock, the issuance of shares of Preferred Stock, or the issuance of rights to
purchase such shares, could be used to discourage an unsolicited acquisition
proposal. For example, the issuance of a series of Preferred Stock might impede
a business combination by including class voting rights that would enable the
holders to block such a transaction; or such issuance might facilitate a
business combination by including voting rights that would provide a required
percentage vote of the stockholders. In addition, under certain circumstances,
the issuance of Preferred Stock could adversely affect the voting power of the
holders of the Common Stock. Although the Board of Directors is required to
make any determination to issue such stock based on its judgment as to the best
interests of the stockholders of the Company, the Board of Directors could act
in a manner that would discourage an acquisition attempt or other transaction
that some or a majority of the stockholders might believe to be in their best
interests or in which stockholders might receive a premium for their stock over
the then-market price of such stock. The Board of Directors does not at present
intend to seek stockholder approval prior to any issuance of currently
authorized stock, unless otherwise required by law or the rules of any market
on which the Company's securities are traded.

STATUTORY BUSINESS COMBINATION PROVISION
 
  The Company is a Delaware corporation and is subject to Section 203 of the
DGCL. In general, Section 203 prevents an "interested stockholder" (defined
generally as a person owning 15% or more of a corporation's outstanding voting
stock) from engaging in a "business combination" (as defined) with a Delaware
corporation for three years following the date such person became an interested
stockholder unless: (i) before such person became an interested stockholder,
the board of directors of the corporation approved the transaction in which the
interested stockholder became an interested stockholder or approved the
business combination; (ii) upon consummation of the transaction that resulted
in the interested stockholder's becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced (excluding stock
held by directors who are also officers of the corporation and by employee
stock plans that do not provide employees with the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer); or (iii) following the transaction in which such
person became an interested stockholder, the business combination was approved
by the board of directors of the corporation and authorized at a meeting of
stockholders by the affirmative vote of the holders of 66 2/3% of the
outstanding voting stock of the corporation not owned by the interested
stockholder. Under Section 203, the restrictions described above also do not
apply to certain business combinations proposed by an interested stockholder
following the announcement or notification of certain extraordinary
transactions involving the corporation and a person who had not been an
interested stockholder during the previous three years or who became an
interested stockholder with the approval of a majority of the corporation's
directors, if such extraordinary transaction is approved or not opposed by a
majority of the directors who were directors prior to any person becoming an
interested stockholder during the previous three years or were recommended for
election or elected to succeed such directors by a majority of such directors.
 
OTHER MATTERS
 
  Delaware law authorizes corporations to limit or eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach of a director's fiduciary duty of care. The duty of care
requires that, when acting on behalf of the corporation, directors must
exercise an informed business judgment based on all material information
reasonably available to them. Absent the limitations authorized by Delaware
law, directors are accountable to corporations and their stockholders for
monetary damages for conduct constituting gross negligence in the exercise of
their duty of care. Delaware law enables corporations to limit available relief
to equitable remedies such as injunction or rescission. The Certificate of
Incorporation limits the liability of directors of the Company to the Company
or its stockholders to the fullest extent permitted by Delaware law.
Specifically, directors of the Company will not be personally liable for
monetary damages for breach of a director's fiduciary duty as a director,
except for liability for unlawful payments of dividends or unlawful stock
repurchases or redemptions as provided in Section 174 of the DGCL.
 
  The inclusion of this provision in the Certificate of Incorporation may have
the effect of reducing the likelihood of derivative litigation against
directors and may discourage or deter stockholders or management from bringing
a lawsuit against directors for breach of their duty of care, even though such
an action, if successful, might otherwise have benefitted the Company and its
stockholders. The Company's Bylaws provide indemnification to the Company's
officers and directors and certain other persons with respect to certain
matters.
 
  The Bylaws provide that stockholders may act only at an annual or special
meeting of stockholders and may not act by written consent. The Bylaws provide
that special meetings of the stockholders can be called only by the Chairman of
the Board, the Chief Executive Officer, the President or the Board of
Directors.
 
  The Certificate of Incorporation provides that the Board of Directors shall
consist of three classes of directors serving for staggered terms. As a result,
it is currently contemplated that approximately one-third of the Company's
Board of Directors will be elected each year. The classified board provision
could prevent a party who acquires control of a majority of the outstanding
voting stock of the Company from obtaining control of the Board of Directors
until the second annual stockholders meeting following the date the acquiror
obtains the controlling interest. See "Management--Directors and Executive
Officers."
 
                                       69
<PAGE>
 
  The Certificate of Incorporation provides that the number of directors shall
be as determined by the Board of Directors from time to time, but shall be at
least one and not more than nineteen. It also provides that directors may be
removed only for cause, and then only by the affirmative vote of the holders of
at least a majority of all outstanding voting stock entitled to vote. This
provision, in conjunction with the provision of the Bylaws authorizing the
Board of Directors to fill vacant directorships, will prevent stockholders from
removing incumbent directors without cause and filling the resulting vacancies
with their own nominees.
 
STOCKHOLDER PROPOSALS
 
  The Company's Bylaws contain provisions: (i) requiring that advance notice be
delivered to the Company of any business to be brought by a stockholder before
an annual meeting of stockholders and (ii) establishing certain procedures to
be followed by stockholders in nominating persons for election to the Board of
Directors. Generally, such advance notice provisions provide that written
notice must be given to the Secretary of the Company by a stockholder: (a) in
the event of business to be brought by a stockholder before an annual meeting,
not less than 90 days prior to the anniversary date of the immediately
preceding annual meeting of stockholders (with certain exceptions if the date
of the annual meeting is different by more than specified amounts from the
anniversary date), and (b) in the event of nominations of persons for election
to the Board of Directors by any stockholder, (i) with respect to an election
to be held at the annual meeting of stockholders, not less than 90 days prior
to the anniversary date of the immediately preceding annual meeting of
stockholders (with certain exceptions if the date of the annual meeting is
different by more than specified amounts from the anniversary date), and (ii)
with respect to an election to be held at a special meeting of stockholders for
the election of directors, not later than the close of business on the 10th day
following the day on which notice of the date of the special meeting was mailed
to stockholders or public disclosure of the date of the special meeting was
made, whichever first occurs. Such notice must set forth specific information
regarding such stockholder and such business or director nominee, as described
in the Company's Bylaws. The foregoing summary is qualified in its entirety by
reference to the Company's Bylaws, which are included as an exhibit to the
Registration Statement of which this Prospectus is a part.

                            PRINCIPAL STOCKHOLDERS
   
  The following table sets forth certain information, on a pro forma basis as
of December 31, 1997 to reflect the mandatory conversion to Common Stock of
certain classes of the Company's capital stock and other convertible
securities upon completion of the Offering, and after giving effect to the
completion of the Offering and such mandatory conversion, with respect to the

known by the Company to be a beneficial owner of more than 5% of any class of
the Company's voting capital stock; (ii) each executive officer and director

they have sole voting and investment power with respect to the shares of
capital stock shown as beneficially owned by them. Unless otherwise indicated,
each person or group has sole voting and investment power with respect to all
such shares. Unless otherwise indicated, the number of shares and percentage
of ownership of Common Stock for each of the named stockholders, directors,
director nominee and executive officers assumes that shares of Common Stock
that the stockholders, directors, director nominee and executive officers may
acquire within 60 days are outstanding.

                        SHARES ELIGIBLE FOR FUTURE SALE
   
  Upon consummation of the Offering, the Company will have 10,381,433 shares
of Common Stock outstanding (10,831,433 if the Underwriters' over-allotment
option is exercised in full) of which 3,000,000 shares sold in the Offering
(3,450,000 if the Underwriters' over-allotment option is exercised in full)
will be freely tradable without restriction or further registration under the
Securities Act unless purchased by "affiliates" of the Company (as defined in
the Securities Act). The remaining 7,093,240 shares of Common Stock and
288,193 shares of Non- Voting Common Stock are deemed "restricted securities"
under Rule 144 in that they were originally issued and sold by the Company in
private transactions in reliance upon exemptions under the Securities Act, and
may be publicly sold only if registered under the Securities Act or sold in
accordance with an applicable exemption from registration, such as those
provided by Rule 144 promulgated under the Securities Act as described below.
    
  In general, under Rule 144 as currently in effect, if a minimum of one year
has elapsed since the later of the date of acquisition of restricted
securities from the issuer or from an affiliate of the issuer, the acquiror or
subsequent holder would be entitled to sell within any three-month period a
number of those shares that does not exceed the greater of one percent of the
number of shares of such class of stock then outstanding or the average weekly
trading volume of the shares of such class of stock during the four calendar
weeks preceding the filing of a Form 144 with respect to such sale. Sales
under Rule 144 are also subject to certain manner of sale provisions and
notice requirements and to the availability of current public information
about the issuer. In addition, if a period of at least two years has elapsed
since the later of the date of acquisition of restricted securities from the
issuer or from any affiliate of the issuer, and the acquiror or subsequent
holder thereof has not been an affiliate of the issuer at any time during the
90 days preceding a sale, such person would be entitled to sell such
restricted securities under Rule 144(k) without regard to the volume
limitations and manner of sale and notice requirements described above. Rule
144 does not require the same person to have held the securities for the
applicable periods. The foregoing summary of Rule 144 is not intended to be a
complete description thereof. The Commission has proposed certain amendments
to Rule 144 that would, among other things, eliminate the manner of sale
requirements and revise the notice provisions of that rule. The SEC has also
solicited comments on other possible changes to Rule 144, including possible
revisions to the one- and two-year holding periods and the volume limitations
referred to above.
   
  As of December 31, 1997, options to purchase an aggregate of 1,623,442
shares of Common Stock were outstanding under the 1995 Stock Option Plan. See
"Management--1995 Stock Option Plan." In general, pursuant to Rule 701 under
the Securities Act, any employee, officer or director of, or consultant to,
the Company who purchased his or her shares pursuant to a written compensatory
plan or contract is entitled to rely on the resale provisions of Rule 701,
which permit non-affiliates to sell such shares without compliance with the
public information, holding period, volume limitation or notice provisions of
Rule 144, and permit affiliates to sell such shares without compliance with
the holding period provisions of Rule 144, in each case commencing 90 days
after the date of this Prospectus. In addition, the Company intends to file a
registration statement covering the 1,980,517 shares issuable upon exercise of
stock options that may be granted in the future under the 1995 Stock Option
Plan, in which case such shares of Common Stock generally will be freely
tradable by non-affiliates in the public market without restriction under the
Securities Act.     
 
  The Company, its executive officers, directors, and current stockholders
have agreed not to offer, sell, contract to sell, grant any option or other
right for the sale of, or otherwise dispose of any shares of Common Stock or
any securities, indebtedness or other rights exercisable for or convertible or
exchangeable into Common Stock owned or acquired in the future in any manner
prior to the expiration (the "180-Day Lockup Period") without the prior
written consent of BancAmerica Robertson Stephens, except that the Company
may, subject to certain conditions, issue Common Stock in connection with
acquisitions and may grant Awards (or Common Stock upon exercise of Awards)
under the 1995 Stock Option Plan. These restrictions will be applicable to any
shares acquired by any of those persons in the Offering or otherwise during
the 180-Day Lockup Period. Approximately     shares of Common Stock issued by
the Company in October and November, 1997 were
 
                                      73
<PAGE>
 
issued subject to agreements in which the persons who received the shares of
Common Stock in connection with acquisitions agreed not to transfer the shares
for periods ranging from 14 to 42 months following consummation of the
Offering.
 
  Prior to the Offering, there has been no established public market for the
Common Stock. No prediction can be made of the effect, if any, that sales of
shares under Rule 144, or otherwise, or the availability of shares for sale
will have on the market price of the Common Stock prevailing from time to time
after the Offering. The Company is unable to estimate the number of shares that
may be sold in the public market under Rule 144, or otherwise, because such
amount will depend on the trading volume in, and market price for, the Common
Stock and other factors. Nevertheless, sales of substantial amounts of shares
in the public market, or the perception that such sales could occur, could
adversely affect the market price of the Common Stock of the Company. See
"Underwriting."

  The Underwriting Agreement provides that the obligations of the Underwriters
to purchase the shares of Common Stock are subject to certain conditions, and
that, if any of the foregoing shares of Common Stock are purchased by the
Underwriters pursuant to the Underwriting Agreement, then all the shares of
Common Stock agreed to be purchased by the Underwriters pursuant to the
Underwriting Agreement must be so purchased.
 
  The Representatives have advised the Company that the Underwriters propose to
offer the shares of Common Stock in part directly to the public at the public
offering price set forth on the cover page of this Prospectus and to certain
dealers at such public offering price less a selling concession not in excess
of $    per share, of which $    may be reallowed to other dealers. After the
consummation of this Offering, the public offering price, the concession to
selected dealers and the reallowance may be changed by the Underwriters. No
such reductions shall change the amount of proceeds to be received by the
Company as set forth on the cover page of this Prospectus.
   
  The Company has granted the Underwriters an option to purchase up to 450,000
additional shares of Common Stock at the initial public offering price less the
underwriting discounts and commissions shown on the cover page of this
Prospectus, solely to cover over-allotments, if any. Such option may be
exercised at any time until 30 days after the date of the Underwriting
Agreement. To the extent that the option is exercised, each Underwriter will be
committed, subject to certain conditions, to purchase a number of additional
shares of Common Stock proportionate to such Underwriter's initial commitment
as indicated in the preceding table.     
 
  The Underwriting Agreement contains covenants of indemnity among the
Underwriters and the Company against certain civil liabilities, including
liabilities under the Securities Act.
 
  The Company, its executive officers, directors and current stockholders have
agreed not to, directly or indirectly, offer for sale, sell, contract to sell,
grant any option or other right for the sale of, or otherwise dispose of (or
enter into any transaction or device which is designed to, or could be expected
to, result in the disposition by any person at any time in the future of) any
shares of Common Stock or any securities, indebtedness or other rights
exercisable for or convertible or exchangeable into shares of Common Stock
prior to the expiration of 180 days after the date of this Prospectus, without
the prior written consent of BancAmerica Robertson Stephens, except that the
Company may, subject to certain conditions, issue shares of Common Stock in
connection with acquisitions and grant Awards (or issue shares of Common Stock
upon exercise of Awards) under the 1995 Stock Option Plan. For information
respecting additional restrictions on sales by the Company's executive
officers, directors and current stockholders, see "Shares Eligible for Future
Sale."

  The Representatives have advised the Company that, pursuant to Regulation M
under the Securities Act, certain persons participating in the Offering may
engage in transactions, including stabilizing bids, syndicate covering
transactions or the imposition of penalty bids, which may have the effect of
stabilizing or maintaining the market price of the Common Stock at a level
above that which might otherwise prevail in the open market. A "stabilizing
bid" is a bid for or the purchase of the Common Stock on behalf of the
Underwriters for the purpose of fixing or maintaining the price of the Common
Stock. A "syndicate covering transaction" is the bid for or the purchase of the
Common Stock on behalf of the Underwriters to reduce a short position incurred
by the Underwriters in connection with the Offering. A "penalty bid" is an
arrangement permitting the Representatives to reclaim the selling concession
otherwise accruing to an Underwriter or syndicate member in connection with the
Offering if the Common Stock originally sold by such Underwriter or syndicate
member is purchased by the Representatives in a syndicate covering transaction
and has, therefore, not been effectively placed by such Underwriter or
syndicate member. The Representatives have advised the Company that such
transactions may be effected on the Nasdaq National Market or otherwise and, if
commenced, may be discontinued at any time.
 
  Prior to the Offering, there has been no public market for the Company's
securities. The initial public offering price of the Common Stock will be
determined by negotiation among the Company and the Representatives. Among the
factors to be considered in such negotiations will be prevailing market
conditions, the results of operations of the Company in recent periods, market
valuations of publicly traded companies that the Company and the
Representatives believe to be comparable to the Company, estimates of the
business potential of the Company, the present state of the Company's
development, the current state of the industry and the economy as a whole, and
other factors deemed relevant.
   
  The Company has applied to have the Common Stock approved for quotation on
the Nasdaq Stock Markets National Market under the symbol "PHCO." There can be
no assurance, however, that an active or orderly trading market will develop
for the Common Stock or that the Common Stock will trade in the public markets
subsequent to the offering at or above the initial public offering price.     
 
  The Representatives have informed the Company that the Underwriters do not
intend to confirm sales of shares of Common Stock offered hereby to accounts
over which they exercise discretionary authority.
 
                                 LEGAL MATTERS
 
  The validity of the shares of Common Stock offered hereby will be passed upon
for the Company by Jackson Walker L.L.P., Dallas, Texas. Certain legal matters
in connection with the sale of the Common Stock offered hereby will be passed
upon for the Underwriters by Alston & Bird LLP, Atlanta, Georgia.

  After the reverse stock split discussed in Note 10 to the financial
statements of Physician Health Corporation and Subsidiaries is effected, we
expect to be in a position to render the following audit report.     
   
ARTHUR ANDERSEN LLP     
   
Atlanta, Georgia     
   
December 15, 1997     
 
                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Physician Health Corporation
and Subsidiaries:
   
  We have audited the accompanying consolidated balance sheets of PHYSICIAN
HEALTH CORPORATION (a Delaware corporation) AND SUBSIDIARIES (Successor
Company) as of December 31, 1995 and 1996 and September 30, 1997, and the
related consolidated statements of operations, stockholders' equity (deficit),
and cash flows for the period from inception (August 29, 1995) through
December 31, 1995, the year ended December 31, 1996, and the nine months ended
September 30, 1997. We have also audited for Physician Health Corporation and
Subsidiaries (Predecessor Company) the accompanying consolidated statements of
operations, stockholders' equity (deficit), and cash flows for the year ended
December 31, 1994 and the period from January 1, 1995 to October 31, 1995.
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 Physician Health
Corporation and Subsidiaries (Successor Company) as of December 31, 1995 and
1996 and September 30, 1997, and the results of their operations and their
cash flows for the period from inception (August 29, 1995) through December
31, 1995, the year ended December 31, 1996, and the nine months ended
September 30, 1997 and for the Predecessor Company for the year ended December
31, 1994 and the period from January 1, 1995 to October 31, 1995 in conformity
with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
         
      DECEMBER 31, 1995 AND DECEMBER 31, 1996 AND SEPTEMBER 30, 1997     
    
 (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 IS UNAUDITED)     
 
1. OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Description of Business
   
  PHC Merger Corporation (the "Company") was incorporated on August 29, 1995
as a Delaware corporation. On November 3, 1995, the Company acquired, in a
transaction accounted for as a purchase, all of the outstanding common stock
of Physician Health Corporation (the "Predecessor Company"), a wholly owned
subsidiary of Surgical Health Corporation, which was a wholly owned subsidiary
of HealthSouth Corporation. The purchase price was approximately $1,325,000.
The Predecessor Company commenced operations during 1994. Upon completion of
the merger, the Company changed its name to Physician Health Corporation (the
"Successor Company"). The Company is a physician management company focusing
on the integration of managed care contracting, network development and
administration, physician practice management and ancillary health care
services development in selected markets. The Company provides these services
to independent physician networks and Company sponsored physician networks and
to physicians who affiliate with the Company through practice management or
employment agreements. The Company currently provides services described above
in the following geographical markets: Virginia, Georgia, Texas, Alabama,
Tennessee, Florida, Missouri, and Arizona.     
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of the Company
and its wholly owned and greater than 50%-owned subsidiaries. Significant
intercompany accounts and transactions have been eliminated in consolidation.
 
 Minority Interests
   
  Minority interests represents the minority shareholders' proportionate share
of the equity of three of the Company's subsidiaries. The Company owns 80% of
the capital stock of two of these subsidiaries with 20% owned by minority
interests. These two subsidiaries were acquired in 1997. The Company owns 51%
of another subsidiary with 49% owned by minority interests.     
   
  As of December 31, 1995 and 1996 and September 30, 1997, the minority
interests are recorded at zero as cumulative losses applicable to minority
interests exceeded the minority interests in the subsidiaries' capital. For
the period ended December 31, 1995, the year ended December 31, 1996, and the
nine months ended September 30, 1997, the minority interests' net loss was
recorded at $797, $0, and $2,080,975, respectively, and $20,100, $268,824, and
$451,963, respectively, of the net loss was absorbed by the Company.     
 
 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 revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Net Loss Per Common and Common Equivalent Share
 
  Net loss per common and common equivalent share is computed using the
weighted average number of shares of common stock and dilutive common stock
equivalent shares ("CSEs") from stock options using the treasury stock method.
Pursuant to the Securities and Exchange Commission Staff Accounting Bulletins,
common stock and CSEs issued at prices below the expected public offering
price during the 12-month period

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
prior to filing of the registration statement in connection with the Company's
planned Offering have been included in the calculation as if they were
outstanding for all periods presented prior to the Offering, regardless of
whether they are dilutive.
 
 New Accounting Pronouncements
   
  In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings Per Share." SFAS No. 128 is designed to improve the
earnings per share information provided in the financial statements by
simplifying the existing computational guidelines, revising the disclosure
requirements, and increasing the comparability of earnings per share data.
SFAS No. 128 is effective for periods ending after December 15, 1997,
including interim periods. The Company will adopt SFAS No. 128 for the fiscal
and interim periods ending December 31, 1997. As of September 30, 1997, the
disclosure requirements of SFAS No. 128 would not require a different
presentation of earnings per share than currently presented due to the
antidilutive effect of all common stock equivalents.     
 
  In February 1997, the Financial Accounting Standards Board issued SFAS No.
129, "Disclosure of Information About Capital Structure." SFAS No. 129
requires companies to disclose descriptive information about an entity's
capital structure. It also requires disclosure of information about the
liquidation preference of preferred stock and redeemable stock. SFAS No. 129
is effective for the Company's fiscal year ending December 31, 1998. The
Company does not expect that SFAS No. 129 will require significant revision of
prior disclosures.
 
  In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income." SFAS No. 130 is designed to improve the
reporting of changes in equity from period to period. SFAS No. 130 is
effective for fiscal years beginning after December 15, 1997. The Company will
adopt SFAS No. 130 for fiscal 1998. Management does not expect SFAS No. 130 to
have a significant impact on the Company's financial statements.
 
  In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information." SFAS
No. 131 requires that an enterprise disclose certain information about
operating segments. SFAS No. 131 is effective for financial statements for the
Company's fiscal year ending December 31, 1998. The Company does not expect
that SFAS No. 131 will require significant revision of prior disclosures.
   
  The Emerging Issues Task Force of the FASB has recently issued its Consensus
Opinion 97-2 ("EITF 97-2"). EITF 97-2 addresses certain specific matters
pertaining to the physician practice management industry. EITF 97-2 would be
effective for the Company for its year ending December 31, 1998. EITF 97-2
addresses the ability of physician practice management companies to
consolidate the results of physician practices with which it has an existing
contractual relationship. The Company is still in the process of analyzing the
effect on all of its contractual relationships, but currently believes that
certain contracts would meet the criteria of EITF 97-2 for consolidating their
results of operations, which would require the Company to restate its
financial statements to reflect such consolidation. EITF 97-2 also has
addressed the accounting method for future combinations with individual
physician practices. The Company believes that, based upon the criteria, set
forth in EITF 97-2, that virtually all of its future acquisitions of
individual physician practices will continue to be accounted for under the
purchase method of accounting.     
 
 Interim Unaudited Financial Information
   
  The financial statements for the nine months ended September 30, 1996 are
unaudited; however, in the opinion of management, all adjustments (consisting
solely of normal recurring adjustments) necessary for a fair presentation of
the unaudited financial statements for these interim periods have been
included. The results of interim periods are not necessarily indicative of the
results to be obtained for a full year.

 Prior Year Reclassifications
 
  Certain prior year and period amounts have been reclassified to conform with
the current year presentation.
 
 Cash Equivalents
 
  The Company considers cash on deposit with financial institutions and all
highly liquid investments with original maturities of three months or less to
be cash equivalents.
 
 Revenue
   
  The Company primarily generates management fee revenues from contracts for
providing management services to physician practices, for organizing and
managing capitated network contracts, and for providing administrative
services such as accounting, billing, and collections. The Company also
generates net patient revenues through employed physicians.     
   
  Revenue is recognized as services are performed. The Company had two
practices that represented 35% of total revenues for the year ended December
31, 1996 and three practices that represented 73% of total revenues for the
nine months ended September 30, 1997.     
   
  Net patient revenues are recorded based on standard charges applicable to
all patients. Under Medicare, Medicaid, and other reimbursement programs, each
practice is reimbursed for services rendered to covered program patients as
determined by reimbursement formulas. The differences between established
billing rates and the amounts reimbursable by the programs and patient
payments are recorded as contractual adjustments and deducted from revenues.
    
 Accounts Receivable and Allowance for Doubtful Accounts
 
  The Company provides an allowance for doubtful accounts equal to the
estimated losses expected to be incurred in the collection of accounts
receivable.
   
 Capitated Contracts     
   
  The Company establishes accruals for its capitated contracts reimbursements
based upon historical trends. Any contracts that would have a guaranteed loss
would be immediately accrued for and the loss would be charged to operations.
    
 Industry Risks
 
  The health care industry is subject to numerous laws and regulations at all
levels of government. These laws and regulations include, but are not
necessarily limited to, matters such as licensure, accreditation, government
health care program participation requirements, reimbursement for patient
services, and Medicare and Medicaid fraud and abuse. Recently, government
activity has increased with respect to investigations and allegations
concerning possible violations of fraud and abuse statutes and regulations by
health care providers. Violations of these laws could result in significant
fines and penalties as well as significant payments for services previously
billed. The Company is subject to similar regulatory reviews. A determination
of liability under any such laws could have a material effect on the Company's
financial position, results of operations, changes in stockholders' equity,
and cash flows.
 
 Property and Equipment
 
  Property and equipment are recorded at cost and are depreciated on a
straight-line basis over the estimated useful lives of the assets, which are
as follows:
 
<TABLE>
   <S>                                                      <C>
   Equipment............................................... Five years
   Furniture and fixtures.................................. Five to seven years
   Leasehold improvements.................................. Ten years
</TABLE>
 
                                     F-13
<PAGE>
 
                 PHYSICIAN HEALTH CORPORATION AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Additions that extend the lives of the assets are capitalized, while repairs
and maintenance costs are expensed as incurred. When property and equipment is
retired, the cost of the property and equipment and the related accumulated
depreciation or amortization are removed from the balance sheet and any
resulting gain or loss is recorded.
 
 Intangible Assets
 
  The Company's acquisitions involve the purchase of tangible and intangible
assets and the assumption of certain liabilities of the affiliated physician
groups. The Company allocates the purchase price to the tangible assets
acquired and liabilities assumed based on estimated fair market values. In
connection with each acquisition, the Company enters into long-term service
agreements with the affiliated physician groups. The service agreements are
for terms of 40 years and cannot be terminated by either party without cause,
primarily bankruptcy or material default. The service agreement intangible is
being amortized using a straight-line method over an average life of 25 years.
 
  In connection with the allocation of the purchase price to identifiable
intangible assets, the Company analyzes the nature of each group with which a
service agreement is entered into, including the number of physicians in each
group, number of service sites, ability to recruit additional physicians, the
group's relative market position, the length of time the group has been in
existence, and the term and enforceability of the service agreement.
 
  The physician groups continually recruit physicians and, as appropriate and
necessary, add qualified physicians to the group. This manner of operations
allows the physician group to perpetuate itself as individual physicians
retire or are otherwise replaced. Therefore, the Company believes that the
physician groups with which it has service agreements are entities with
indeterminable life.
       
 Income Taxes
 
  The Company is a corporation subject to federal and state income taxes.
Income taxes have been provided using the liability method in accordance with
the Statement of financial accounting standards ("SFAS") No. 109, "Accounting
for Income Taxes."
 
 Impairment of Long-Lived Assets
 
  On January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of."
Under SFAS No. 121, intangibles are reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of the asset may
not be recoverable. If this review indicates that the carrying amount of the
asset may not be recoverable, as determined based on the undiscounted cash
flows of the operations acquired over the remaining amortization period, the
carrying value of the asset is reduced to fair value. Among the factors that
the Company will continually evaluate are unfavorable changes in each
physician group's relative market share and local market competitive
environment, current period and forecasted operations, cash flow levels of the
physician group, and its impact on the management fee earned by the Company,
and legal factors governing the practice of medicine. In 1996, the Company
wrote off certain fixed assets for $195,236. In 1997, the Company wrote off
certain fixed assets and intangible assets for $714,665.
 
2. ACQUISITIONS
   
  During the year ended December 31, 1996, the Company purchased the assets of
one physician practice ("Metropoliton Plastic & Reconstructive Surgery"). The
Company issued a note in the amount of $500,000 and issued 125,000 shares of
the Company's prime stock.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
   
  During the nine months ended September 30, 1997, the Company acquired
certain assets and assumed certain liabilities of eleven physician practices
located in Texas, Missouri, Georgia, Illinois and Arizona. These practices
were:     
                    
                 Surgical Group South        Ream Optometry     

                    
                 Eye Medical and Surgical    Tri-County Eye Center      
                                                 
                                                                        
                 The Heart Health Center     Atlanta Center for Medicine      

                                                                              
                 Jones Eye Center            Southern Dependacare      

                                                                       
                 Arlington Cancer Center     Surgical Associates      

                                                                      
                 Payson Family Care     
   
Total tangible assets acquired were $9,188,823 and total liabilities assumed
were $2,000,762. To consummate these eleven 1997 acquisitions and reflect
entry into related practice management agreements, the Company paid
$18,325,928 in cash, issued debt in the aggregate amount of $13,177,187, and
issued 2,833,613 and 97,407 shares of the Company's prime and common stock
respectively. In addition, consideration was given in the form of a 20%
interest in two newly formed subsidiaries. This 20% minority interest in the
subsidiaries are convertible into 2,080,975 shares of common stock in the
Company. The aggregate value of common and prime stock issued was $6,155,553.
As a result of these acquisitions, the Company recorded intangibles of
approximately $17,000,000 (after purchased research and development), which is
being amortized over 25 years. These acquisitions were accounted for as
purchase transactions, and the acquired net assets and post acquisition
operating results are included in the September 30, 1997 consolidated
financial statements.     

   
  In connection with the acquisition of a physician practice during the nine
months ended September 30, 1997, the Company allocated $13,251,860 to
purchased research and development. Based on management's assessment of no
alternative future benefit to the Company, this amount was charged against
operations on the date of the acquisition.

5. RELATED-PARTY TRANSACTIONS
 
  At December 31, 1995, the Company had outstanding notes payable to officers
and shareholders totaling $363,375. The notes bear interest at 10%. The
proceeds from these notes were used to repay a portion of the line of credit
to Surgical Health Corporation. The notes payable were paid in full in January
1996. Interest paid to related parties was $5,874.
 
  The Company had an intercompany line of credit with Surgical Health
Corporation prior to November 3, 1995 totaling $1,342,893. This line of credit
was paid in full on November 3, 1995, with the proceeds from the issuance of
shares of common stock and related party loans.
   
  The Company maintains management services agreements to provide services to
and receive compensation from physicians that own stock in the Company or the
Company's subsidiaries and physicians that are on the Company's board of
directors. At September 30, 1997, the Company maintains eight management
service contracts that were initiated in connection with asset purchases in
which the Company issued common stock as consideration (Note 2). For the year
ended December 31, 1996 and the nine months ended September 30, 1997, the
Company recognized total management service fees from the contracts of
approximately $62,000 and $9,500,000, respectively. The Company also recorded
capitated contract fees of $140,000 between two of its subsidiaries, however,
amounts eliminate in consolidation.     
   
  The Company pays monthly consulting fees to affiliated investors and members
of the board for consulting services received. For the nine months ended
September 30, 1997, the Company paid approximately $1,410,000 in consulting
fees to affiliates.     
   
  At September 30, 1997, the Company has fourteen promissory notes due to
shareholders of the Company. The total amount due to shareholders is
$2,524,692.     
   
  In connection with the exercise of stock options during 1997, the Company
received a note in the amount of $443,750 from a stockholder of the Company.
    
6. REDEEMABLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY (DEFICIT)
 
 Class A Redeemable Convertible Preferred Stock
   
  During 1995, 200,000 shares of class A redeemable convertible preferred
stock were issued to certain investors of the Company. At any time prior to
December 29, 2005, each share of preferred stock is convertible into 3.01
common shares, as adjusted.     
   
  The conversion rate of the Class A stock shall be adjusted in the event that
the Company: (1) has a liquidity event, as defined, on or prior to December
31, 1997, (2) attains certain levels of profitability, (3) issues common

then in effect, (4) declares a stock dividend, (5) declares a stock split, or
(6) is recapitalized. Automatic conversion will occur upon the closing of a
liquidity event (including an initial public offering).     
   
  The holders of Class A stock are entitled to dividends on a converted basis,
if declared by the Company's board of directors, at a per share amount, if
any, of any dividend declared for the common stock during the period. In
addition, the stockholders are entitled to receive cumulative dividends of
$1.50 per share (subject to adjustment for any stock splits) per annum. Such
dividends began accruing on December 31, 1996 and are payable annually
beginning in 1998. Dividends have been accrued as of September 30, 1997.     
   
  The Class A holders have a liquidation preference of $15 per share plus 12%
per annum from the date of purchase. The 12% compounded annual rate of return
shall be in lieu of, not in addition to, the dividends paid or payable by the
Company. The Class A stock is senior to the common stock with respect to
liquidation and dividends.     
          
  After December 31, 2000, each share of Class A stock is redeemable at the
request of the holder. The redemption price is equal to the greater of $15 per
share plus any declared and unpaid dividends or the fair market value of the
Class A stock at the time of redemption. The Class A stock is required to be
redeemed, at the holders request if the principals, as defined, sell 20% or
more of the outstanding shares of capital stock of the Company, become
insolvent, have a breach of warranty under the purchase agreement, or have an
acceleration of debt in excess of $500,000 in the aggregate. No shares have
been redeemed as of September 30, 1997. At September 30, 1997, the Company
recorded accretion of preferred stock of $104,492. Accretion is being
calculated on a straight-line basis, which approximates the interest method.
    
 Series B Redeemable Convertible Preferred Stock
   
  The Company is authorized to issue 15,000,000 shares of Series B Redeemable
Convertible Preferred Stock at $.01 par value in one or more series. This type
of stock has been issued pursuant to several securities purchase agreements
among the Company, and certain other investors. Holders of Series B
Convertible Preferred Preferred Stock are generally entitled to (1) accrue a
dividend in an amount equal to 20% per annum, compounded annually, on $4,
beginning on the later of the original issue date or the date on which the
purchase price for such shares was first released from the applicable purchase
price escrow (holders will also receive a special contingent dividend upon the
consummation of a Liquidity Event), (2) liquidation preference over holders of
common and prime stock in the amount of $4 per share plus accrued and unpaid
dividends, and (3) vote as a single class with the holders of common stock
based on the number of shares of common stock into which the Series B
preferred stock may be converted. All regular dividends are forgiven upon the
occurrence of a Liquidity Event.     
   
  Under mandatory redemption, Series B Redeemable Convertible Preferred Stock
is redeemable at a price equal to $4 per share, as adjusted, plus accrued and
unpaid dividends. Mandatory redemption will commence in 2003.     
   
  Each share of Series B Redeemable Convertible Preferred Stock is convertible
at the option of the holder at any time into the number of shares of the
common stock of the Company obtained by dividing $4 by the then effective
conversion price of the Series B Redeemable Convertible Preferred Stock.
Provided that a liquidity event has not occurred prior to May 1, 2002, the
conversion price will be $4 per share, and after May 1, 2002, the conversion
price will be $3 per share. Automatic conversion will occur upon the closing
of a liquidity event (including an initial public offering).     
   
  The conversion rate of the Series B Redeemable Convertible Preferred Stock
shall be adjusted in the event (1) the Company issues additional shares of
common stock at a price that is less than the applicable conversion price in
effect on the date of, and immediately prior to, such issue, (2) stock is
issued as a dividend, (3) stock is subdivided or diluted, or (4) the
outstanding shares of common stock are combined or consolidated into a lesser
number of shares of common stock.

 Common Stock
   
  On October 6, 1995, 706,500 shares of common stock were issued to certain
employees at a price of $.0025 per share of which 1,125,000 shares were vested
immediately. Subject to each stockholder maintaining full-time employment, the
unvested shares of common stock shall vest ratably over future periods. The
shares of the unvested stock have been placed in escrow. The holders of these
unvested shares have full voting rights through the escrow agent. All of the
common stock shall vest immediately in the event the Company: (1) achieves a
certain minimum market value and is merged with another company; (2)
consummates an initial public offering with a certain minimum level of
proceeds; or (3) is merged, consolidated, or reorganized resulting in a change
of control of the Company. These shares are subject to certain transfer
restrictions and may be forfeited if an employee leaves the Company for
reasons other than retirement, disability or death, absent a change in control
of the Company.     
   
  Through a private placement offering which closed on November 3, 1995, an
additional 345,400 shares of common stock were issued at a price of $3.18 per
share.

the Company has a management agreement.     
   
  During the nine-month period ended September 30, 1997, the Company issued
217,904 shares to various shareholders for cash of $2,611,464 and for the
final settlement to NationsCredit in the amount of $160,000 in connection with
the termination of the credit agreement.     
 
 Prime Common Stock
   
  The Company has been authorized to issue 20 million shares of prime common
stock with a par value of $.0025 per share. Holders of prime common stock are
entitled to the following: (1) to vote one-tenth of one share with respect to
any matters voted upon by the stockholders of the Company, (2) the right to
receive dividends when declared by the Board of Directors of the Company,
provided that the per share amount is at least equal to the per share amount
declared for common stockholders, and (3) the right to receive a pro rata
share of distributions upon a "distribution event" by the Company after
payment of outstanding debt and other obligations, subject to the preferences
of Class A, Class B, and common stockholders. The fair market value of prime
common stock is determined periodically by outside appraisers. Outstanding
shares of prime common stock will convert to common stock, on a .314 to 1
basis, as adjusted, upon the Company's completion of a public offering in
which the sale of common stock results in net proceeds of $20 million or more.
    
  On November 26, 1996, the Company issued 125,000 shares of prime common
stock at $1 per share in connection with the acquisition of the assets of

  During the nine months ended September 30, 1997, the Company issued
3,385,518 shares of prime common stock in connection with the purchase of nine
physician practices (Note 2). The Company also issued 166,152 shares related
to exercise of stock options. The consideration for this exercise was in the
form of cash and issuance of notes receivable.     
 
 Employee Stock Option Plans and Investor Warrants
 
  The Company has nonqualified and incentive stock option plans to provide key
employees and directors and consultants of the Company with an increased
incentive to work for the success of the Company. The Company also issues
investor warrants to investors of the Company. The option price for all stock
options and warrants is usually the market value at the date of grants and
thus, the plans are generally noncompensatory. The options and warrants expire
ten years after the dates of their respective grants.
   
  The Company accounts for the stock options and warrants under APB Opinion
No. 25, which requires compensation costs to be recognized only when the
option price differs from the market price at the grant date. FASB Statement
No. 123 allows a company to follow APB Opinion No. 25 with an additional
disclosure that shows what the Company's pro forma net loss would have been
using the compensation model under FASB Statement No. 123. The pro forma loss
for the year ended December 31, 1996 and the nine-month period ended June 30,
1997 was $3,605,446 and $17,235,754, respectively. The Company used the
minimum value method to estimate the fair values of options and warrants for
the pro forma determination. For purposes of the minimum value method, the
Company used U.S. Treasury strip rates for its risk-free rates, assumed no
volatility or future dividends, and assumed the expected lives of the options
and warrants through the applicable expiration dates.     
   
  The Company reserved a total of approximately 9,000,000 shares of common
stock for issuance to holders of employee stock options and investor warrants.
       
  Stock option activity (adjusting prime stock options for their common stock
conversion) from inception date, August 29, 1995 to September 30, 1997 is
summarized as follows:

7. INCOME TAXES
 
  Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and unused tax operating loss carryforwards.
   
  Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts for income tax purposes. Significant components of
the Company's deferred tax liabilities and assets are as follows at December
31, 1995 and 1996 and September 30, 1997:

8. CONTINGENCIES
   
  The Company and its affiliated physician groups are insured with respect to
medical malpractice risks on a claims-made basis. In the opinion of
management, the amount of potential liability with respect to these claims
will not materially affect the Company's financial position or results of
operations.     
 
  Under the terms of a management service agreement to provide medical service
to a managed care organization in Central Florida, the Company, through a 51%-
owned subsidiary, is required to place $250,000 in escrow after a minimum
number of members are assigned to the Company for medical care. The escrow
fund is to be used to fund quarterly losses, if any, for the provision of
medical care. The Company currently has $50,000

in escrow, as the minimum number of participants has not been obtained. Losses
beyond the amount placed in escrow are the responsibility of the managed care
organization. If a quarterly profit exists for two consecutive quarterly
periods, any amounts remaining in escrow are paid to the Company. The
agreement does not require amounts withdrawn from escrow to be replenished.
 
9. COMMITMENTS
   
  The Company leases office space and certain equipment under operating lease
agreements which expire at various years through 2002. Operating leases may be
renewed for periods ranging from three to five years. At September 30, 1997,
minimum annual rental commitments under capital leases and noncancellable

(August 29, 1995) to December 31, 1995, the year ended December 31, 1996, and
the nine months ended September 30, 1997, respectively.     
 
10. SUBSEQUENT EVENTS
   
  Since September 30, 1997, the Company purchased 18 physician practices
located in Atlanta, Cincinnati, Memphis, Orlando, and St. Louis. The total
purchase price for the acquisitions was approximately $42 million, which was
paid for through the issuance of common stock, debt, and payment of cash. The
practices will be accounted for as asset acquisitions by the Company under the
purchase method of accounting.     
   
  Subsequent to September 30, 1997, the Company entered into a line of credit
with a bank for a maximum amount of $62,500,000 to fund the acquisitions noted
above.     
   
  The board of directors has approved a .314 to 1 reverse stock split. This
reverse stock split is awaiting and will be effective upon receipt of
shareholder approval. Accordingly, the financial statements reflect the
reverse stock split as if it had occurred at the beginning of each period
presented.

standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of

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 Metroplex

                          DECEMBER 31, 1995 AND 1996
   
(INFORMATION AS OF MAY 31, 1997 AND FOR THE FIVE MONTHS ENDED MAY 31, 1996 AND
                           1997 IS UNAUDITED).     
 
1. ORGANIZATION
 
  Metroplex Hematology/Oncology Associates, L.L.P. (the Partnership) is a
Texas limited liability partnership formed in January 1980. The Partnership
operates and manages a medical practice in Arlington, Texas, specializing in
internal medicine, hematology, oncology, diagnostic radiology and
radiotherapy, and provides related laboratory and clinical services.
 
  The Partnership has a term until December 31, 2050 or until a terminating
event (as defined) occurs. The formation as a limited liability partnership
during 1994 allows for a limitation to the partners on their exposure to
professional liability claims.
 
2. ACCOUNTING POLICIES
 
 Partnership Basis of Presentation
 
  The financial statements include only those assets, liabilities and results
of operations that relate to the business of the Partnership. The statements
do not include assets, liabilities or results of operations attributable to
the partners' individual activities.
 
 Income Taxes
 
  Income taxes are an obligation of the partners and, accordingly, are not
provided for in the financial statements. The partners include their
proportionate shares of Partnership net income or loss in their individual
income tax returns.
 
 Property and Equipment
 
  Property and equipment are recorded at cost. Depreciation and amortization
of assets owned or under capital leases are computed using straight-line and
accelerated methods over estimated useful lives ranging from 5 to 31 years.
 
 Cash and Cash Equivalents
 
  Cash equivalents are highly liquid money market instruments with original
maturities of less than 90 days.
 
 Concentration of Credit Risk
 
  Cash and cash equivalents used in operations consist primarily of cash in
financial institutions in checking and money market accounts and investments
in short-term money market mutual funds.
 
  Concentration of credit risk relating to accounts receivable is limited to
some extent by the diversity and number of patients and payors. The
Partnership performs ongoing credit evaluations of its payors and maintains
allowances for potential credit losses.
 
 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 amounts reported in the financial statements and
 
                                     F-27

               METROPLEX HEMATOLOGY/ONCOLOGY ASSOCIATES, L.L.P.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
related notes. Actual results could differ from these estimates and
assumptions. The primary areas of estimation affecting the accompanying
financial statements include the determination of the allowance for doubtful
accounts, contractual adjustments and the liability for medical malpractice
risks.
 
 Health Insurance Program Reimbursement
 
  The Partnership operates and manages a medical practice in Arlington, Texas.
Revenues from the Medicare and Medicaid programs combined accounted for
approximately 22% of the Partnership's net medical fees for the years ended
December 31, 1995 and 1996. Laws and regulations governing the Medicare and
Medicaid programs are complex and subject to interpretation. The Partnership
believes that it is in compliance with all applicable laws and regulations and
is not aware of any pending or threatened investigations involving allegations
of potential wrongdoing. While no such regulatory inquires have been made,
compliance with such laws and regulations can be subject to future government
review and interpretation as well as significant regulatory action including
fines, penalties, and exclusion from the Medicare and Medicaid programs.
 
 Revenue Recognition
 
  Patient revenues are recognized net of contractual adjustments related to
third-party payors and the Medicare and Medicaid programs. The amount paid by
the third-party payors is dependent upon the benefit included in the patient's
policy or amounts contractually established between the Partnership and the
third-party payors.
   
 Interim Unaudited Financial Information     
   
  The financial statements as of May 31, 1997 and for the five months ended
May 31, 1996 and 1997 are unaudited; however, in the opinion of management,
all adjustments (consisting solely of normal recurring adjustments) necessary
for a fair presentation of the unaudited financial statements for these
interim periods have been included. The results of interim periods are not
necessarily indicative of the results to be obtained for a full year.     
 
3. PROPERTY AND EQUIPMENT
 
  Property and equipment consist of the following at December 31:

  The Partnership maintains a $250,000 revolving line of credit. There were no
borrowings outstanding at December 31, 1995 or 1996. Additionally, the note
agreements contain certain restrictive covenants that require the Partnership
to maintain minimum net worth, as defined in the note agreements, of
$1,500,000.
 
  The Partnership's debt approximates fair value based on current incremental
borrowing rates for similar types of borrowing arrangements.
 
  Maturities of long-term debt for the three years succeeding December 31,
1996, are as follows:

5. OPERATING LEASES
 
  The Partnership leases office space and equipment under operating leases
expiring at various dates through 2004. Some of the office space lease
agreements include an escalation clause based on increases in the U.S.
Consumer Price Index (CPI). Such possible increases are not considered in
computing future minimum lease payments.
 
  Future minimum annual rental payments under noncancelable operating leases
are as follows at December 31, 1996:

6. RELATED PARTY TRANSACTIONS
 
  The partners, individually, have invested in certain ventures outside of the
Partnership and are guarantors of the debt of such ventures.
 
  The partners are also partners of R-M Medical Plaza I, L.P. (RM-I) and
certain partners are partners of R-M Medical Plaza II, L.P. (RM-II), which are
real estate partnerships whose sole purpose is to purchase and operate medical
office buildings. Included in rent expense is rent of $1,056,000 for 1995 and
1996 related to RM-I and $185,000 for 1995 and $202,000 for 1996 relating to
RM-II.
 
  During the year, the Partnership advanced funds on behalf of RM-II. Amounts
owed the Partnership by RM-II were approximately $80,000 as of December 31,
1995 and $102,000 as of December 31, 1996.
 
7. COMMITMENTS AND CONTINGENCIES
 
  The partnership agreement provides that partners terminating after December
31, 1995 with ten or more years of service to the Partnership will receive an
additional payment. The additional payment is determined by multiplying the
partner's interest in the Partnership by the profits of the Partnership for
the fiscal year preceding the terminating event and this amount is payable
over 60 months. At December 31, 1996, two of the seven partners were eligible
for this additional payment in the amount of $1,447,887. This amount is not
accrued in the financial statements and is unfunded.
 
  During 1994, a partner retired from the practice and the Partnership
obligated itself to pay him $555,000 for consulting services to be performed.
The obligation bears no interest and is payable ratably over the next five
years regardless of when consulting services are requested by the Partnership.
Of the obligation, $304,000 has been paid through December 31, 1996. The
related asset has been amortized in full as of December 31, 1996.
 
  An RM-II loan from a bank is secured by guarantees of certain partners and
of the Partnership who are each jointly and severally liable for the balance
of the loan ($1,791,410 at December 31, 1996). Additionally, the Partnership
has agreed to certain covenants in the loan agreement that, among other
things, require the

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
maintenance of certain financial ratios, restrict the issuance of new debt,
limit the amount of future investments, and restrict the amount of
distributions to the partners.
 
8. EMPLOYEE BENEFIT PLAN
 
  The Partnership participates in a defined contribution plan, established in
May 1989. Employees who have completed one year of service and attained the
age of 21 are eligible to participate. Participants contribute a voluntary
amount that is matched by the Partnership at 50% of the employee's
contribution, up to 5% of the employee's salary. Participants are fully vested
in their voluntary contributions. Participants vest in the Partnership's
contributions 20% upon completion of two years of vesting service and 20% for
each of the next four years. The Partnership contributed to the plan
approximately $91,000 in 1995 and $98,000 in 1996, which amounts are included
in salaries and benefits in the accompanying statements of income.
 
9. LITIGATION
 
  In the ordinary course of business, the partners and or the Partnership are
sometimes named as defendants in various legal proceedings although there are
no current matters pending. The results of litigation cannot be predicted with
certainty; however, the Partnership maintains claims-made insurance coverage
and historically litigation, when it arises, will be adequately covered by
insurance and will not have a material adverse effect on the Partnership's
financial statements.
 
10. AGREEMENT TO SELL CERTAIN ASSETS
 
  Subsequent to December 31, 1996, the Partnership formally entered into an
agreement to sell certain assets of the Partnership, as well as, an agreement
whereby an independent company will manage the physicians' medical practice.
The agreements are contingent upon the closing of the transaction, which is
expected to include cash, notes and stock in the newly created company. The
Partnership is expected to continue operations after the transaction.
   
11. PRO FORMA INCOME TAXES (UNAUDITED)     
   
  The income taxes on earnings of the partnership is the responsibility of the
partners. The pro forma adjustments reflected on the statements of income
assume this partnership was subject to income taxes. Pro forma income tax
expense has been calculated using statutory federal and state tax rates,
estimated at 39%.

            NINE MONTHS ENDED SEPTEMBER 30, 1996 IS UNAUDITED)     
 
1. ORGANIZATION AND OPERATIONS
 
  Greater Cincinnati Gastroenterology Associates, Inc., an Ohio corporation,
(the "Company") was incorporated in 1968. The Company currently employs nine
physicians and over 30 employees. The physicians specialize in the diagnosis
and treatment of diseases of the digestive system. There are currently twelve
office locations throughout the Greater Cincinnati area.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Unaudited Financial Information
   
  The financial statements for the nine months ended September 30, 1996 are
unaudited; however, in the opinion of management, all adjustments (consisting
solely of normal recurring adjustments) necessary for a fair presentation of
the unaudited financial statements for these interim periods have been
included. The results of interim periods are not necessarily indicative of the
results to be obtained for a full year.     
 
 Cash and Cash Equivalents
 
  Cash and cash equivalents include cash on hand and in checking and money
market accounts.
 
 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 the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
 Accounts Receivable
 
  Accounts receivable principally represents receivable from patients and
third-party payers for medical services provided by physician-owners and
employees. Such amounts are recorded net of estimated contractual allowances.
Contractual adjustments result from the differences between the rates charged
by the physicians for services performed and the amounts allowed by the
Medicare and Medicaid programs and other public and private insurers.
 
 Property and Equipment
 
  Property and equipment are recorded at cost. Depreciation is computed using
the straight-line method for financial reporting purposes and accelerated
methods for tax purposes.
 
  The useful lives of property and equipment are as follows:
 
<TABLE>
   <S>                                                        <C>
   Equipment................................................. Five years
   Furniture and fixtures.................................... Seven years
   Leasehold improvements.................................... Life of the lease
</TABLE>
 
  Maintenance and repairs are charged to expense as incurred. The cost of
renewals and betterments is capitalized and depreciated over the applicable
estimated useful lives.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Owners' Equity
 
  Owners' equity includes the respective capital stock owned by physician-
owners, additional paid-in capital, and retained earnings of the Company.
Various types of agreements exist among the owners which call for the transfer
of a physician's ownership interest to the continuing owners in the case of
certain events such as the owner's retirement or death.
 
 Net Patient Service Revenues
 
  Patient service revenues are reported at the estimated realizable amounts
from patients, third-party payers (which include managed care providers,
commercial insurance carriers, and health maintenance organizations), and
others for services rendered. Additionally, the Company participates in
agreements with managed care organizations to provide services at negotiated
rates.
 
 Concentration of Credit Risk
 
  The Company extends credit to patients covered by governmental programs such
as Medicare and Medicaid and by private insurers. The Company manages credit
risks with the various public and private insurance providers as appropriate.
Allowances for doubtful accounts have been made for potential losses where
appropriate.
 
3. PROPERTY AND EQUIPMENT

4. INCOME TAXES

financial reporting purposes. Deferred income taxes arise from temporary
differences between financial and income tax reporting of various items
(principally revenue recognition).

rise to the deferred tax assets and liabilities at December 31, 1996 and
September 30, 1997:

7. LEGAL PROCEEDINGS
 
  The Company is subject to legal proceedings and third-party claims which
arise in the ordinary course of business. In the opinion of management, the
amount of potential liability with respect to these actions will not

8. RELATED-PARTY TRANSACTIONS
   
  For the year ended December 31, 1996 and the nine months ended September 30,
1997, the Company expensed approximately $150,500 and $118,000, respectively,
in rent and maintenance for one of its locations in Cincinnati which is owned
by certain physician-owners.     
   
  The Company provides medical treatment of endoscopic patients for a clinical
research company owned by certain physician-owners. For the year ended
December 31, 1996, and the nine months ended September 30, 1997 the Company
recognized approximately $64,000 and $59,000, respectively, in fee income and
was reimbursed for approximately $208,000 and $142,000, respectively, for

owners. These operating expenses primarily were specifically incurred by the
physician-owners with minimal allocation of expenses.     
   
  The Company shares certain operating costs with a surgical center owned by
an independent third party. During 1996 and the first nine months of 1997, the
Company was reimbursed approximately $31,000 and $18,800, respectivley, for
such specifically identifiable costs. In addition, certain patients received a
global charge for services performed by the Company and the surgical center.
The global fee is then paid to the Company. In 1996 and the nine months of
1997, the Company paid $27,000 and $2,300, respectively, to the surgical
center for its share of global fees received by the Company.     
 
  During the first five months of 1996, the Company leased office space from a
partnership owned by certain physician-owners. The Company expensed

31, 1996.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Internal Medicine Specialists, Inc.:
   
  We have audited the accompanying balance sheet of INTERNAL MEDICINE
SPECIALISTS, INC., (a Florida corporation), as of December 31, 1996 and
September 30, 1997 and the related statements of operations, owners' equity,
and cash flows for the year ended December 31, 1996 and the nine months ended
September 30, 1997. 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.

                         NOTES TO FINANCIAL STATEMENTS
                    
                 DECEMBER 31, 1996 AND SEPTEMBER 30, 1997     
       
    (INFORMATION FOR THE NINE MONTHS ENDED JUNE 30, 1996 IS UNAUDITED)     
       
1. ORGANIZATION AND OPERATIONS
 
  Internal Medicine Specialists, Inc. (the "Company") was incorporated in the
state of Florida on October 27, 1971. The Company currently has 14 physicians,
7 nephrologists, and 7 gastroenterologists. The physicians within the group
primarily focus on kidney and stomach surgery. There are currently three
office locations in Orlando and Ocoee, Florida.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Unaudited Financial Information
   
  The financial statements for the nine months ended September 30, 1996 are
unaudited; however, in the opinion of management, all adjustments (consisting
solely of normal recurring adjustments) necessary for a fair presentation of
the unaudited financial statements for these interim periods have been
included. The results of interim periods are not necessarily indicative of the
results to be obtained for a full year.     
 
 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 the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
 Cash and Cash Equivalents
 
  Cash and cash equivalents include cash on hand and in checking and money
market accounts.
 
 Accounts Receivable
 
  Accounts receivable principally represent receivables from patients and
third-party payers for medical services provided by physician owners and
employees. Such amounts are recorded net of estimated contractual allowances
and bad debts. Contractual adjustments result from the differences between the
rates charged by the physicians for services performed and the amounts allowed
by the Medicare and Medicaid programs and other public and private insurers.
 
 Property and Equipment
 
  Property and equipment are recorded at cost. Depreciation is computed using
the straight-line method over the estimated service lives of depreciable
assets (five years for equipment, five to seven years for furniture and
fixtures, and ten years for leasehold improvements). Maintenance and repairs
are charged to expense as incurred. The cost of renewals and betterments is
capitalized and depreciated over the applicable estimated useful lives. The
cost and accumulated depreciation of assets sold, retired, or otherwise
disposed of are removed from the accounts, and the related gain or loss is
credited or charged to income.
 
 Owners' Equity
 
  Owners' equity includes the respective capital stock owned by 12 physician-
owners and treasury stock repurchased by the Company from two terminated
physician-owners, recorded at cost. Various types of

                      INTERNAL MEDICINE SPECIALISTS, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
agreements exist among the owners which call for the repurchase of a
physician's ownership interest by the Company in the case of certain events,
such as the owner's termination, retirement, or death.
 
 Net Patient Service Revenues
 
  Patient service revenues are reported at the estimated realizable amounts
from patients, third-party payers (which include managed care providers,
commercial insurance carriers, and health maintenance organizations), and
others for services rendered. Additionally, the Company participates in
agreements with managed care organizations to provide services at negotiated
rates or for capitated payments.
 
 Concentration of Credit Risk
 
  The Company extends credit to patients covered by insurance programs,
including governmental 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 doubtful accounts have
been made for potential losses, where appropriate.

  Property and equipment at December 31, 1996 and September 30, 1997 consisted

1. ORGANIZATION AND OPERATIONS
   
  Parkcrest Surgical Associates, Inc. (the "Company") was incorporated in
1969. The Company operates a medical practice at various locations and
provides surgical and other health care services to individuals in the St.
Louis Metropolitan Area. The physicians within the group specialize in general
surgery, spinal surgery, colo-rectal surgery, vascular surgery, sports
medicine, orthopedic surgery, surgical oncology, plastic and reconstructive
surgery, hand surgery, podiatric surgery, and physical medicine and
rehabilitation. There are currently 17 physicians and 5 physician assistants.
    
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Unaudited Financial Information
   
  The financial statements for the six months ended September 30, 1996 are
unaudited; however, in the opinion of management, all adjustments (consisting
solely of normal recurring adjustments) necessary for a fair presentation of
the unaudited financial statements for these interim periods have been
included. The results of interim periods are not necessarily indicative of the
results to be obtained for a full year.     
   
 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 the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
   
 Cash and Cash Equivalents     
 
  Cash and cash equivalents include cash on hand and in checking and money
market accounts.
 
 Property and Equipment
 
  Equipment and leasehold improvements are carried at cost, less accumulated
depreciation and amortization computed using straight-line and accelerated
methods. Equipment and furniture and fixtures are depreciated over periods
ranging from 3 to 5 years. Leasehold improvements are amortized over periods
ranging from 3 to 40 years.
 
 Accounts Receivable
 
  Accounts receivable principally represent receivables from patients and
third-party payers for medical services provided by physician owners and
employees. Such amounts are recorded net of estimated contractual allowances.
Contractual adjustments result from the differences between the rates charged
by the physicians for services performed and the amounts allowed by the
Medicare and Medicaid programs and other public and private insurers.
 
 Net Patient Service Revenues
 
  Patient service revenues are reported at the estimated realizable amounts
from patients, third-party payers (which include managed care providers,
commercial insurance carriers, and health maintenance organizations),

and others for services rendered. Additionally, the Company participates in
agreements with managed care organizations to provide services at negotiated
rates.
 
 Owners' Equity
 
  Owners' equity includes the respective capital stock owned by various
physician-owners and treasury stock repurchased by the Company from terminated
physician-owners, recorded at cost. Various types of agreements exist among
the owners which call for the repurchase of a physician's ownership interest
by the Company in the case of certain events, such as the owner's termination,
retirement, or death.
 
 Concentration of Credit Risk
 
  The Company extends credit to patients covered by insurance programs such as
governmental programs like Medicare and Medicaid and private insurers. The
Company manages credit risk with the various public and private insurance
providers, as appropriate. Allowances for doubtful accounts have been made for
potential losses, where appropriate.

7. INCOME TAXES
 
  The provision for income taxes is based on net income reported for financial
reporting purposes. Deferred income taxes arise from temporary differences
between financial and income tax reporting of various items (principally
revenue recognition).
   
  The following details the temporary differences and carryforwards giving
rise to the deferred tax assets and liabilities at March 31, 1997 and
September 30, 1997:

conduct, salary, and benefits provisions.

amount of potential liability with respect to these actions will not
materially affect the Company's financial position or results of operations.

                         NOTES TO FINANCIAL STATEMENTS
                     
                  DECEMBER 31, 1996 AND AUGUST 31, 1997     
     
  (INFORMATION FOR THE EIGHT MONTHS ENDED AUGUST 31, 1996 IS UNAUDITED)     
       
1. THE ORGANIZATION AND OPERATIONS
 
  Southern Dependacare, Inc., an Alabama corporation, (the "Company") was
organized in 1990. The Company currently has 4 physicians, specializing in
oncology and cancer care. There are 3 rural networks of clinics located in
Carbondale, Illinois; Natchez, Mississippi; and Abbington, Virginia.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Unaudited Financial Information
   
  The financial statements for the eight months ended August 31, 1996 are
unaudited; however, in the opinion of management, all adjustments (consisting
solely of normal recurring adjustments) necessary for a fair presentation of
the unaudited financial statements for these interim periods have been
included. The results of interim periods are not necessarily indicative of the
results to be obtained for a full year.     
 
 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 the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
 Cash and Cash Equivalents
 
  Cash and cash equivalents include cash on hand and in checking and money
market accounts.
 
 Accounts Receivable
 
  Accounts receivable principally represent receivables from patients and
third-party payers for medical services provided by physician owners and
employees. Such amounts are recorded net of estimated contractual allowances
and bad debts. Contractual adjustments result from the differences between the
rates charged by the physicians for services performed and the amounts allowed
by the Medicare and Medicaid programs and other public and private insurers.
 
 Property and Equipment
 
  Property and equipment are recorded at cost. Depreciation is computed on the
straight-line method over the estimated service lives of depreciable assets
(five to seven years for equipment, and seven years for furniture and
fixtures). Maintenance and repairs are charged to expense as incurred. The
cost of renewals and betterments is capitalized and depreciated over the
applicable estimated useful lives. The cost and accumulated depreciation of
assets sold, retired, or otherwise disposed of are removed from the accounts,
and the related gain or loss is credited or charged to income.
 
 Owner's Equity
 
  Owner's equity includes the respective capital stock, partnership capital
and retained earnings of the Company. The capital stock of the Company is
wholly-owned by one physician.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Net Patient Service Revenues
 
  Patient service revenues are reported at the estimated realizable amounts
from patients, third-party payers (which include managed care providers,
commercial insurance carriers, and health maintenance organizations), and
others for services rendered. Additionally, the Company participates in
agreements with managed care organizations to provide services at negotiated
rates or for capitated payments.
 
 Concentration of Credit Risk
 
  The Company extends credit to patients covered by insurance programs such as
governmental programs like Medicare and Medicaid and private insurers. The
Company manages credit risk with the various public and private insurance
providers, as appropriate. Allowances for doubtful accounts have been made for
potential losses, where appropriate.
 
3. PROPERTY AND EQUIPMENT
   
  Property and equipment at December 31, 1996 and August 31, 1997 consists of
the following:

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Delaware General Corporation Law
 
  Section 145(a) of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a corporation may indemnify any person 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 corporation)
by reason of the fact that he is or was a director, officer, employee or agent
of the corporation, or is or was serving at the request of the corporation as
a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, 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 in a manner he 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 reasonable cause to believe his conduct
was unlawful. The termination 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 person 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 corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his
conduct was unlawful.
 
  Section 145(b) of the DGCL states that a corporation may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he
is or was a director, officer, employee or agent of the corporation, or is or
was serving at the request or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection with the defense
or settlement of such action or suit 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
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in
 
                                     II-1
<PAGE>
 
which such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.
 
  Section 145(c) of the DGCL provides that to the extent that a director,
officer, employee or agent of a corporation has been successful on the merits
or otherwise in defense of any action, suit or proceeding referred to in
subsections (a) and (b) of Section 145, or in defense of any claim, issue or
matter therein, he shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection therewith.
 
  Section 145(d) of the DGCL states that any indemnification under subsections
(a) and (b) of Section 145 (unless ordered by a court) shall be made by the
corporation only as authorized in the specific case upon a determination that
indemnification of the director, officer, employee or agent is proper in the
circumstances because he has met the applicable standard of conduct set forth
in subsections (a) and (b). Such determination shall be made (1) by the board
of directors by a majority vote of a quorum consisting of directors who were
not parties to such action, suit or proceeding, or (2) if such a quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (3) by the
stockholders.
 
  Section 145(e) of the DGCL provides that expenses (including attorneys'
fees) incurred by an officer or director in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such director or
officer to repay such amount if it shall ultimately be determined that he is
not entitled to be indemnified by the corporation as authorized in Section
145. Such expenses (including attorneys' fees) incurred by other employees and
agents may be so paid upon such terms and conditions, if any, as the board of
directors deems appropriate.
 
  Section 145(f) of the DGCL states that the indemnification and advancement
of expenses provided by, or granted pursuant to, the other subsections of
Section 145 shall not be deemed exclusive of any other rights to which those
seeking indemnification or advancement of expenses may be entitled under any
bylaw, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office.
 
  Section 145(g) of the DGCL provides that a corporation shall have the power
to purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the corporation
would have the power to indemnify him against such liability under the
provisions of Section 145.
 
  Section 145(j) of the DGCL states that the indemnification and advancement
of expenses provided by, or granted pursuant to, Section 145 shall, unless
otherwise provided when authorized or ratified, continue as to a person who
has ceased to be a director, officer, employee or agent, and shall inure to
the benefit of the heirs, executors and administrators of such a person.
 
 Certificate of Incorporation
 
  The Certificate of Incorporation provides that a director of the Company
shall not be personally liable to the Company or its stockholders for monetary
damages for breach of fiduciary duty as a director, except for liability for
unlawful payments of dividends or unlawful stock repurchases or redemptions as
provided for in Section 174 of the DGCL. If the DGCL is amended to authorize
the further elimination or limitation of the liability of directors, then the
liability of a director of the Company, in addition to the limitation on
personal liability described above, shall be limited to the fullest extent
permitted by the amended DGCL. Further, any
 
                                     II-2
<PAGE>
 
repeal or modification of such provision of the Certificate of Incorporation
by the stockholders of the Company shall be prospective only, and shall not
adversely affect any limitation on the personal liability of a director of the
Company existing at the time of such repeal or modification.
 
 Bylaws
 
  The Bylaws of the Company provide that the Company will indemnify and hold
harmless any director or officer of the Company to the fullest extent
permitted by applicable law, as in effect as of the date of the adoption of
the Bylaws or to such greater extent as applicable law may thereafter permit,
from and against all losses, liabilities, claims, damages, judgments,
penalties, fines, amounts paid in settlement and expenses (including
attorneys' fees) whatsoever arising out of any event or occurrence related to
the fact that such person is or was a director or officer of the Company and
further provide that the Company may, but is not required to, indemnify and
hold harmless any employee or agent of the Company or a director, officer,
employee or agent of any other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise who is or was serving in such
capacity at the written request of the Company; provided, however, that the
Company is only required to indemnify persons serving as directors, officers,
employees or agents of the Company for the expenses incurred in a proceeding
if such person has met the standards of conduct that make it permissible under
the laws of the State of Delaware for the Company to indemnify the claimant
for the amount claimed, but the burden of proving such defense will be on the
Company. The Bylaws further provide that, in the event of any threatened, or
pending action, suit or proceeding in which any of the persons referred to
above is a party or is involved and that may give rise to a right of
indemnification under the Bylaws, following written request by such person,
the Company will promptly pay to such person amounts to cover expenses
reasonably incurred by such person in such proceeding in advance of its final
disposition upon the receipt by the Company of (i) a written undertaking
executed by or on behalf of such person providing that such person will repay
the advance if it is ultimately determined that such person is not entitled to
be indemnified by the Company as provided in the Bylaws and (ii) satisfactory
evidence as to the amount of such expenses.
 
 Underwriting Agreement
 
  The Underwriting Agreement provides for the indemnification of the directors
and officers of the Company in certain circumstances.
 
 Insurance
 
  The Company intends to maintain liability insurance for the benefit of its
directors and officers.

ITEM 17. UNDERTAKINGS.
 
  The undersigned registrant hereby undertakes as follows:
 
    (1) To provide to the Underwriters at the closing specified in the
  Underwriting Agreement certificates in such denominations and registered in
  such names as required by the Underwriters to permit prompt delivery to
  each purchaser.
 
    (2) Insofar as indemnification for liabilities arising under the
  Securities Act may be permitted to directors, officers and controlling
  persons of the registrant pursuant to the provisions described in Item 14,
  or otherwise, the registrant has been advised that in the opinion of the
  Commission such indemnification is against public policy as expressed in
  the Securities Act and is, therefore, unenforceable. In the event that a
  claim for indemnification against such liabilities (other than the payments
  by the registrant of expenses incurred or paid by a director, officer or
  controlling person of the registrant in the successful defense of any
  action, suit or proceeding) is asserted by such director, officer or
  controlling person in connection with the securities being registered, the
  registrant will, unless in the opinion of its counsel the matter has been
  settled by controlling precedent, submit to a court of appropriate
  jurisdiction the question whether such indemnification by it is against
  public policy as expressed in the Securities Act and will be governed by
  the final adjudication of such issue.
 
    (3) That, for the purposes of determining any liability under the
  Securities Act, the information omitted from the form of prospectus filed
  as part of this registration statement in reliance upon Rule 430A and
  contained in a 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.
 
    (4) That, for the purpose 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.

     Re:  Registration Statement on Form S-1 of Physician Health Corporation
          ------------------------------------------------------------------


Ladies and Gentlemen:

     We are acting as counsel for Physician Health Corporation, Inc., a Delaware
Corporation (the "Company"), in connection with the registration under the
Securities Act of 1933, as amended (the "Act"), of the offering and sale of up
to 3,000,000 shares (and up to an additional 450,000 shares to cover
Underwriters' overallotments) of the Company's Common Stock, par value $0.0025
per share (the "Shares"), which Shares are issuable in connection with the
Company's initial public offering. A Registration Statement (as amended, the
"Registration Statement") on Form S-1 (No. 333-40073) covering the offering and
sale of the Shares was filed with the Securities and Exchange Commission (the
"Commission") on November 12, 1997.

     In reaching the conclusions expressed in this opinion, we have examined and
relied upon originals or certified copies of all documents, certificates, and
instruments as we have deemed necessary to the opinions expressed herein.  In
making the foregoing examinations, we have assumed the genuineness of all
signatures on original documents, the authenticity of all documents  submitted
to us as originals and the conformity to original documents to all copies
submitted to us.

     Based solely upon the foregoing, subject to the comments hereinafter
stated, and limited in all respects to the laws of the State of Texas, the
General Corporation Law of the State of Delaware and the federal laws of the
United States of America, it is our opinion that the Shares, when sold in
accordance with the terms of the Underwriting Agreement, the form of which forms
an exhibit to the Registration Statement, will be validly and legally issued,
fully paid and nonassessable.

     You should be aware that we are not admitted to practice law in the State
of Delaware.  Accordingly, any opinion herein as to the laws of the State of
Delaware is based solely upon the latest generally available compilation of the
statutes and case law of such state.

within the category of persons whose consent is required under Section 7 of the
Act or the rules and regulations of the Commission promulgated thereunder.


                                       Very truly yours,

         I.7      Conversion of Shares.
                  --------------------
 
                  (a) On the Effective Date, all of the then outstanding shares
of capital stock of Target (the "Target Shares") shall be converted into a total
of four hundred thousand eight hundred and sixty eight dollars ($429,865) in
cash and 786,098 shares of the Voting Common Stock of PHC (the "PHC Shares"),
and all outstanding certificates evidencing shares of capital stock of Target
shall be canceled.

                                                                          Page 2
<PAGE>
 
                  (b) In addition to the shares to be issued by PHC to the
Shareholders pursuant to Section 1.7(a) above, PHC shall issue and deliver to
the Shareholders additional shares of its Voting Common Stock (the "Contingent
Shares") pursuant to the terms and conditions set forth in Section 1.7(c) below;
provided, however, in no event shall the number of Contingent Shares to be
issued to the Shareholders under this Section 1.7(b) exceed the number of PHC
Shares initially issued to the Shareholders pursuant to Section 1.7(a) above.

                  (c) The determination of the amount, if any, of the Contingent
Shares that shall be issued to the Shareholders, shall be made pursuant to the
terms and conditions set forth in this Section 1.7(c) as follows:

                      (i) The parties hereby acknowledge and agree that a
portion of the PHC Shares to be issued to the Shareholders pursuant to Section
1.7(a) hereof was determined by reference to an amount equal to one hundred
percent (100%) of the "Adjusted Accounts Receivable" (as defined below) of
Target as of the Closing Date. The "Adjusted Accounts Receivable" of Target
shall be determined by taking the actual amount of accounts receivable on
Target's books and records as of the Closing Date, less any of Target's accounts
receivable that, in the aggregate (1) are more than one (1) year old with no
payments having been made to Target during the twelve (12) consecutive months
ending on the Closing Date, or (2) were turned over to a collection agency, an
attorney or a third party for collection prior to such date, and multiplying
such remainder by Target's accounts receivable collection ratio (as determined
by dividing Target's total collections by Target's total charges) for the twelve
(12) consecutive month period preceding the Closing Date.

                      (ii) On the one hundred eightieth (180th) day following
the Closing Date, the Adjusted Accounts Receivable shall be compared to the
actual collections during said one hundred eighty (180) day period of those
accounts receivable on the books and records of Target on the Closing Date. In
the event that the actual collections during said one hundred eighty (180) day
period exceeds the Adjusted Accounts Receivable, PHC shall issue to the
Shareholders (on a pro rata basis) that number of Contingent Shares under this
Section 1.7(c) (based on a value of Four Dollars ($4.00) per share) necessary to
equal such excess amount. In the event that the Adjusted Accounts Receivable
exceeds the actual collections during said one hundred eighty (180) day period
of those accounts receivable on the books and records of Target on the Closing
Date, the Shareholders, on a pro rata basis, shall return to PHC that number of
PHC Shares (based on a value of Four Dollars ($4.00) per share) necessary to
equal such excess amount.

                  (d) The parties hereby acknowledge and agree that the
Contingent Shares shall not be issued by PHC, and shall not be considered
outstanding stock, until such time as the certificates for any Contingent Shares
hereunder are actually delivered to the Shareholders in accordance with this
Section 1.7, that no party shall have any voting rights with respect to the
Contingent Shares until actually issued to the Shareholders in accordance with
this Section 1.7, and that the Shareholders' rights to receive the Contingent
Shares shall be nontransferable and nonassignable.

                                                                          Page 3

         (d) The parties hereby acknowledge and agree that the Contingent
Shares shall not be issued by PHC, and shall not be considered outstanding

are actually delivered to the Shareholders in accordance with this Section 1.7,
that no party shall have any voting rights with respect to the Contingent Shares
until actually issued to the Shareholders in accordance with this Section 1.7,
and that the Shareholders' rights to receive the Contingent Shares shall be
nontransferable and nonassignable.

                  --------------------------------------------

         From and after the Effective Date and until surrendered and exchanged,
each outstanding certificate formerly representing Target Shares shall be deemed
for all purposes to represent only the right to receive the PHC Shares specified
in Section 1.7 hereof. From and after the Effective Date, the stock transfer
books of Target shall be closed, and no transfer of shares on the books of
Target shall be made or recorded.

         I.10     Closing.
                  -------

         The Closing shall occur at such time as all the conditions precedent to

to qualify as a tax-free reorganization within the meaning of (S)(S)

substantially all of Acquisition Subsidiary's properties (except for any assets
of Acquisition Subsidiary distributed to the Shareholders pursuant to the Merger
and any cash of Acquisition Subsidiary used to pay Target's reorganization
expenses as set forth in Section 9.11 hereof). Notwithstanding any other
provision contained in this Agreement to the contrary, the PHC Shares to be
issued to the Shareholders pursuant to the Merger shall in no event constitute
less than eighty percent (80%) of the total consideration to be exchanged
pursuant to the Merger for the Target Shares owned by the Shareholders. Any
adjustment required to be made by this Section 1.12 to the amount of PHC Shares

by all the parties, executed by the parties hereto prior to Closing.

         Schedule 2.4 hereto contains a current list of all the lease agreements

which Target leases (whether as lessor or lessee) or licenses (whether as
licensor or licensee) any real or personal property related to the operation of
the Practice (the "Lease Agreements"). Target has delivered to PHC true and
complete copies of all of the Lease Agreements. Each of the Lease Agreements is
valid and effective in accordance with its terms, and there is not under any of
such Lease Agreements (a) any existing or claimed material default by Target or
event of default or event which with notice or lapse of time, or both, would
constitute a default by Target, or (b) any existing material default by any

received by the Shareholder pursuant to this Agreement as of the Closing Date.
The obligation of Target to indemnify PHC and/or Acquisition Subsidiary shall be

                                                                         Page 30
<PAGE>
 
         VIII.4    Offset.
                   ------

         The foregoing rights of indemnification are cumulative and without
prejudice to any other remedies which a party hereto may have against another
party hereto under applicable law or otherwise. Each Shareholder, Target,
Acquisition Subsidiary and PHC expressly agree that PHC shall have the right to
offset any amounts owed by any Shareholder and/or Target to PHC under this
Article VIII against any amounts payable by PHC to such Shareholder and/or
Target; provided, however, if any such offset amount is disputed in good faith
by Target or any Shareholder, such party shall provide written notice of the
facts in dispute in accordance with the procedures set forth in Section 8.8
hereof and PHC shall only be entitled to offset an amount determined by mutual
agreement of the parties or as awarded in the final decision of the arbitrator.
Each Shareholder, Target, Acquisition Subsidiary and PHC expressly agree that
Target and each Shareholder shall have the right to offset any amounts owed by
PHC and/or Acquisition Subsidiary to Target or the Shareholders under this
Article VIII against any amounts payable by any Shareholder and/or Target to
PHC; provided, however, if any such offset amount is disputed in good faith by
PHC, PHC shall provide written notice of the facts in dispute in accordance with
the procedures set forth in Section 8.8 hereof and Target and/or the
Shareholders shall only be entitled to offset an amount determined by the mutual
agreement of the parties or as awarded in the final decision of the arbitrator.

         VIII.5    Notice and Opportunity to Defend.
                   --------------------------------

                   (a) Attorney-in-Fact is hereby designated the representative
of each Shareholder pursuant to the terms and conditions of Section 4.5 above,
to the extent necessary to give effect to the provisions of this Article VIII,
and in that representative capacity, Attorney-in-Fact is referred to as
Indemnified Party or Indemnifying Party, as appropriate.

                   (b) The party indemnified hereunder (the "Indemnified Party")
shall notify in writing the indemnifying party (the "Indemnifying Party") within
thirty (30) days after a claim is presented to the Indemnified Party, and the
Indemnifying Party shall defend such claim at its expense. If the Indemnifying
Party does not defend or settle such claim, the Indemnified Party may do so
without the Indemnifying Party's participation, in which case the Indemnifying
Party shall pay the expenses of such defense; provided, however, that the
Indemnified Party may not settle or compromise such claim without the consent of
the Indemnifying Party or a majority of the Indemnifying Parties, as the case
may be, which consent shall not be unreasonably withheld. An Indemnifying
Party's failure to object to the settlement of any claim within fifteen (15)
days of receiving written notice thereof shall be deemed to constitute the
Indemnifying Party's consent to such settlement. If the Indemnified Party fails
to notify the Indemnifying Party, and if the Indemnifying Party is thereby
materially prejudiced by such failure of notice in its defense of the claim, the
Indemnifying Party's obligation of indemnity hereunder shall be extinguished
with respect to such claim to the extent that the Indemnifying Party has been
prejudiced by the failure to give such notice.

                                                                         Page 31
<PAGE>
 
                   (c) Anything herein to the contrary notwithstanding, PHC
shall not make any claim against Target or any Shareholder pursuant to this
Article VIII unless the dollar amount of all Losses suffered or incurred by PHC
shall exceed, in the aggregate, the amount of One Hundred Fifty Thousand and
No/100 Dollars ($150,000.00), but, if such amount is exceeded, the Indemnifying
Party shall be required to pay the full amount of such aggregate Losses (with a
deduction for such One Hundred Fifty Thousand and No/100 Dollars ($150,000.00)
threshold amount) for which indemnification rights and obligations are provided
under this Article VIII.

                   (d) Anything herein to the contrary notwithstanding, neither
Target nor any Shareholder shall make any claim against PHC pursuant to this
Article VIII unless the dollar amount of all Losses suffered or incurred by the
party seeking indemnification shall exceed, in the aggregate, the amount of
Fifty Thousand and No/100 Dollars ($50,000.00), but, if such amount is exceeded,
PHC shall be required to pay the full amount of such aggregate Losses (without
deduction for such Fifty Thousand and No/100 Dollars ($50,000.00) threshold
amount) for which indemnification rights and obligations are provided under this
Article VIII.

                   (e) Anything herein to the contrary notwithstanding, no party
shall be liable to any other party under this Article VIII for punitive or
consequential damages, including lost profits, except to the extent contained in
a settlement, award or judgment obtained by a third party.

         VIII.6    Effect of Investigation by PHC.
                   ------------------------------

         No investigation or inquiry made by PHC or Acquisition Subsidiary of
any Shareholder or Target or its books and records and financial condition
shall, regardless of the Closing of the transactions contemplated hereby, affect
or limit any representation or warranty made by any of the Shareholders or
Target to PHC or Acquisition Subsidiary in this Agreement or in any Schedule
delivered by any of them pursuant hereto or any right of indemnification of PHC
or Acquisition Subsidiary under Section 8.1 hereof.

         VIII.7    Effect of Investigation by Target and Shareholders.
                   --------------------------------------------------

         No investigation or inquiry made by the Shareholders or Target of PHC
or Acquisition Subsidiary or their respective books and financial condition
shall, regardless of the Closing of the transactions contemplated hereby, affect
or limit any representation or warranty made by PHC or Acquisition Subsidiary to
Target or the Shareholders in this Agreement or in any Schedule delivered by any
of them pursuant hereto or any right of indemnification of Target or the
Shareholders under Section 8.1 hereof.

                                                                         Page 32

         VIII.8    Dispute Resolution.
                   ------------------

         Any controversy, dispute or claim arising out of or relating to this
Agreement or the breach hereof which cannot be settled by mutual agreement shall
be settled by binding arbitration as follows: Any party who is aggrieved shall
deliver written notice to the other party or parties setting forth the specific
points in dispute. Any points remaining in dispute twenty (20) days after the
giving of such notice shall be submitted to binding arbitration in Atlanta,
Georgia, to the American Arbitration Association, before a single arbitrator
appointed from the members of the National Panel of Arbitrators in accordance
with the rules of the American Arbitration Association, modified only as
expressly provided herein. After such twenty (20) day period, any party, upon
ten (10) days written notice to the other parties, may so submit the points in
dispute to arbitration. The arbitrator may enter a default decision against any
party who fails to participate in the arbitration proceedings. The decision of
the arbitrator on the points in dispute will be final, unappealable and binding,
and judgment on the award may be entered in any court having jurisdiction
thereof. The arbitrator will be authorized to apportion its fees and expenses
and the reasonable attorney fees and expenses of the parties as the arbitrator
deems appropriate. In the absence of any such apportionment, the fees and
expenses of the arbitrator will be borne equally by each party, and each party
will bear the fees and expenses of its own attorney. The parties agree that this
paragraph has been included to rapidly and inexpensively resolve any disputes
between them with respect to this Agreement, that it contains the sole and
exclusive remedy (other than equitable remedies) of the parties with respect to
any disputes arising under this Agreement, and that this paragraph shall be
grounds for dismissal of any court action commenced by either party with respect
to this Agreement, other than post-arbitration actions seeking to enforce an
arbitration award or any court action seeking equitable relief. The parties
shall keep confidential, and shall not disclose to any person, except as may be
required by law, the existence of any controversy hereunder, the referral of any
such controversy to arbitration or the status or resolutions thereof.

     8.3  Definition of Losses.
          -------------------- 
          For the purposes of this Article VIII, "Losses" shall mean any and all
demands, claims, actions or causes of action, assessments, losses, damages,
liabilities, costs, and expenses, including, without limitation, interest,
penalties, and reasonable attorneys' and other professional fees, and expenses
incurred in the investigation, preparation, defense, and settlement of any
claim, loss, damage, or liability as to which a party is entitled to
indemnification hereunder.

     8.4  Offset.
          ------ 
          The foregoing rights of indemnification are cumulative and without
prejudice to any other remedies which PHC and/or Acquisition Subsidiary may have
against any Shareholder, and vice versa, under applicable law or otherwise.
Each Shareholder, Practice Group, Acquisition Subsidiary and PHC expressly agree
that (i) PHC shall have the right to offset any amounts owed by any Shareholder
to PHC under this Article VIII against any amounts payable by PHC to any
Shareholder and (ii) any Shareholder shall have the right to offset any amounts
owed by PHC and/or Acquisition Subsidiary to such Shareholder under this Article
VIII against any amounts payable by such Shareholder to PHC and/or Acquisition
Subsidiary.

     8.5  Notice and Opportunity to Defend.
          -------------------------------- 

    (a)   Attorney-in-Fact is hereby designated the representative of each
          Shareholder pursuant to the terms and conditions of Section 4.6 above,
          to the extent necessary to give effect to the provisions of this
          Article VIII, and in that representative capacity, Attorney-in-Fact is
          referred to as Indemnified Party or Indemnifying Party, as
          appropriate.

    (b)   The party indemnified hereunder (the "Indemnified Party") shall notify
          in writing the indemnifying party (the "Indemnifying Party") within
          thirty (30) days after a claim is presented to the Indemnified Party,
          and the Indemnifying Party shall defend such claim at its expense.  If
          the Indemnifying Party does not defend or settle such claim, the
          Indemnified Party may do so without the Indemnifying Party's
          participation, in which case the Indemnifying Party shall pay the
          expenses of such defense, and the Indemnified Party may settle or
          compromise such claim without the Indemnifying Party's consent.  If
          the Indemnified Party fails to notify the Indemnifying Party, and if
          the Indemnifying Party is thereby materially prejudiced by such
          failure of notice in its defense of the claim, the Indemnifying
          Party's obligation of indemnity hereunder shall be extinguished with
          respect to such claim to the extent that the Indemnifying Party has
          been prejudiced by the failure to give such notice.

    (c)   Anything herein to the contrary notwithstanding, (other than for
          liability related to Section 2.27), no party shall make any claim
          against any other party pursuant to this Article VIII unless the
          dollar amount of all Losses suffered or incurred by the party seeking
          such indemnity hereunder shall exceed, in the aggregate, the amount of
          Fifteen Thousand and No/100 Dollars ($15,000.00), but, if such amount
          is exceeded, the Indemnifying Party shall be required to pay the full
          amount of such aggregate Losses (without deduction for such Fifteen
          Thousand and No/100 Dollars ($15,000.00), threshold amount) for which
<PAGE>
 
          indemnification rights and obligations are provided under this Article
          VIII.  Notwithstanding the foregoing, the indemnification obligation
          of those Shareholders listed on SCHEDULE 8.5 attached hereto shall be
                                          ------------                         
          limited, except with respect to liability relating to Section 2.27, to
          the aggregate amount of consideration they received pursuant to this
          Agreement.

     (d)  Anything herein to the contrary notwithstanding, no party shall be
          liable to any other party under this Article VIII for punitive or
          consequential damages, including lost profits, except to the extent
          contained in a settlement, award or judgment obtained by a third
          party.

     8.6  Effect of Investigation by PHC.
          ------------------------------ 
          No investigation or inquiry made by PHC or Acquisition Subsidiary of
any Shareholder or Practice Group or its books and records and financial
condition shall, regardless of the Closing of the transactions contemplated
hereby, affect or limit any representation or warranty made by any of the
Shareholders or Practice Group to PHC or Acquisition Subsidiary in this
Agreement or in any Schedule delivered by any of them pursuant hereto or any
right of indemnification of PHC or Acquisition Subsidiary under Section 8.1
hereof; provided however, that PHC shall provide written notice to the
Shareholders prior to Closing of any material inaccuracy or deficiency known to
PHC in any of the Schedules hereto delivered by the Shareholders.

     discretion), PHC-SUB shall have the right to bill and collect from patients
     all professional fees for medical services and for ancillary services
     performed at or on behalf of the Service Provider and the Service Provider
     Employees.  The Service Provider hereby appoints PHC-SUB for the term of
     this Agreement as its true and lawful attorney in fact for the following
     purposes:


               (1) To bill patients in the Service Provider's name and on the

          Service Provider Employees;


               (2) To collect accounts receivable generated by such billings in
          the Service Provider's name and on the Service Provider's behalf, and

          the Service Provider hereby covenants to forward such payments to PHC-
          SUB for deposit;


               (4) To take possession of and endorse in the name of the Service
          Provider, or in the name of any Service Provider Employee, any notes,

          received as payment of such accounts receivable; and


               (5) To initiate and pursue legal proceedings in the name of the
          Service Provider: (i) to collect any accounts and moneys owed to the
          Service Provider or any Service Provider Employee; (ii) to enforce the
          rights of the Service Provider as creditors under any contract or in
          connection with the rendering of any service; and (iii) to contest
          adjustments and denials by governmental agencies (or its fiscal
          intermediaries) as third-party payors; provided the initiation and
          pursuit of any such legal proceeding shall require the prior written
          consent of the Service Provider, such consent not to be unreasonably
          withheld.


     (b) PHC-SUB agrees that the Service Provider and only the Service Provider
will perform the medical functions of its practice.  PHC-SUB will have no
authority, directly or indirectly, to perform, and will not perform, any medical
function.  PHC-SUB may, however, advise the Service Provider as to the
relationship (if any) between its performance of medical functions and the
overall administrative and business functioning of its practice.  To the extent

                                       12

that they assist the Service Provider in performing medical functions, all
clinical personnel provided by PHC-SUB who perform patient care services shall
be subject to the professional direction and supervision of the Service Provider
and, in the performance of such medical functions, shall not be subject to any
direction or control by, or create any liability on behalf of, PHC-SUB, except
as may be specifically authorized by PHC-SUB.


     3.6.  PATIENT AND FINANCIAL RECORDS.


     PHC-SUB shall own and maintain all files and records (other than medical

method as reasonably directed by the Service Provider, including, but not
limited to, customary financial records and patient files.  PHC-SUB shall use
its best efforts to manage all files and records in compliance with all
applicable federal, state and local statutes and regulations, and all files and
records shall be located so that they are readily accessible for patient care,
consistent with ordinary records management practices.


     The Service Provider shall supervise the preparation of, and direct the
contents of, patient medical records, all of which shall be and remain
confidential and the property of the Service Provider.  PHC-SUB shall have
reasonable access to such records and, subject to applicable laws, regulations
and accreditation policies, PHC-SUB shall be permitted to retain true and
complete copies of such records.


     3.7.  FINANCIAL STATEMENTS.


     PHC-SUB shall prepare and deliver to the Service Provider monthly financial

with PHC-SUB and contribute reasonable efforts to assist PHC-SUB in its efforts
to pursue Managed Care Relationships.  All decisions regarding initiating or
terminating Managed Care Relationships shall be subject to the review and
approval of the Joint Policy Board. All costs and expenses related to services
provided under this Section 4.3 shall be PHC-SUB Expenses and not Operational

     5.4.  RESTRICTIVE COVENANTS.


     (a) The Service Provider acknowledges and agrees that the services to be
provided by PHC-SUB hereunder are feasible only if the Service Provider operates
a vigorous medical practice to which the Service Provider Employees devote their
full time and attention.  Accordingly, the Service Provider agrees that it shall
not, without the prior written consent of PHC-SUB: (i) during the term of this
Agreement, establish, operate or provide physician services substantially
similar to those professional medical, surgical and related ancillary services
offered by the Service Provider other than pursuant to this Agreement, and (ii)
for a period of 12 months following termination of this Agreement, establish or
otherwise operate a medical office or practice for the purpose of providing
physician services substantially similar to those professional medical, surgical
and related ancillary services offered by the Service Provider pursuant to this
Agreement within five (5) automobile driving miles (as determined in good faith
by PHC-SUB) of the Service Provider's office located at 675 Old Ballas Road,
Suite 200, Creve Coeur, Missouri (the "Restricted Territory"); provided however,
that this sentence shall not prohibit Service Provider after termination of this
Agreement from (i) performing medical services at a hospital or surgical
facility within the Restricted Territory so long as the physicians providing
such services do not establish, or otherwise operate a medical office inside the
Restricted Territory, or (ii) performing medical services at the outpatient
surgery center located at 415 N. New Ballas Road, Creve Coeur, Missouri (the
"Permitted Activities").


     The Service Provider shall obtain, maintain, update (as new Medical
Offices, if any, are established) and reasonably enforce agreements with all its
physician Service Provider Employees except as provided in Section I of EXHIBIT
5.4(A) attached hereto, satisfactory in form and substance to PHC-SUB, pursuant
to which physician Service Provider Employees shall agree: (i) not to establish,
operate or provide physician medical or surgical services substantially similar
to those professional medical, surgical and related ancillary services offered
by the Service Provider other than on behalf of the Service Provider and
pursuant to this Agreement, without the prior written consent of PHC-SUB, during
the term of this Agreement and during such time that such physician is a Service
Provider Employee; and (ii) not to establish or otherwise operate a medical
office for the purpose of providing physician services substantially similar to
those professional medical, surgical and related ancillary services provided by
such physician on behalf of the Service Provider within the Restricted
Territory, for a period of two (2) years following the termination of the
professional relationship between such physician and the Service Provider;
provided however, that this sentence shall not prohibit a physician from
performing Permitted Activities following such termination.  PHC-SUB shall be
expressly named as a third-party beneficiary to such agreements between the
Service Provider and each physician Service Provider Employee.

     (b) In the event that, during the first five (5) years of this Agreement, a
"Covered Physician" (as defined in Section 7.1(a)) terminates his or her
relationship with the Service Provider, other than (i) as a result of death or
permanent disability or (ii) under such circumstances as are set forth in
EXHIBIT 5.4(C) attached hereto, such Covered Physician shall pay to PHC-SUB the
Liquidated Damages as are set forth in EXHIBIT 5.4(B) attached hereto.  Upon the
payment of the Liquidated Damages by a Covered Physician set forth in EXHIBIT
5.4(B) hereto, the Service Provider shall be required to maintain the

                                       16
<PAGE>
 
restrictive covenants set forth in Sections 5.4(a) and 5.4(d) hereof with
respect to such Covered Physician, PHC-SUB shall remain a third-party
beneficiary to such agreement between the Service Provider and such Covered
Physician, and the Covered Physician shall honor the terms and obligations of
the restrictive covenants set forth in Sections 5.4(a) and 5.4(d) hereof with
respect to such agreement between the Service Provider and such Covered
Physician.


     (c) Under such circumstances and upon the payment to PHC-SUB by a Covered
Physician of such Liquidated Damages as are set forth in EXHIBIT 5.4(C) attached
hereto, the Service Provider shall not be required to maintain the restrictive
covenants set forth in Section 5.4(a) hereof with respect to such Covered
Physician and PHC-SUB shall be removed as a third-party beneficiary to such
agreement between the Service Provider and such Covered Physician.


     (d) During the term of this Agreement and for a period of eighteen (18)
months following the termination or expiration of this Agreement, the Service
Provider shall not, without the prior written consent of PHC-SUB, employ, hire
or contract for services with any employee or former employee of PHC-SUB, nor
shall the Service Provider solicit any such person to leave the employ of PHC-
SUB.  For purposes of this Section 5.4(d), a "former employee" shall be any
person who was employed by PHC-SUB within the six (6) months prior to the
termination or expiration of this Agreement.  The Service Provider shall cause
its Service Provider Employees to enter into written agreements, satisfactory in
form and substance to PHC-SUB, pursuant to which such persons shall agree to be
bound by the same restrictions as set forth in this Section 5.4(d) with respect
to the Service Provider and PHC-SUB, and PHC-SUB shall be expressly named as a
third-party beneficiary to such agreements between the Service Provider and each
physician Service Provider Employee.


     (e) If this Agreement is terminated pursuant to Section 8.2(a), 8.2(b),
8.2(c)(iv), 8.2(c)(v) or 8.2(e) hereof, the Service Provider shall not, directly
or indirectly, for a period of two years following the date of such termination,
sell, transfer or otherwise convey all or substantially all of its stock or
assets to, or merge with or into, any other person or entity (or group of
affiliated entities) (an "Acquirer") in connection with which the Acquirer or
any of its affiliates shall provide or arrange for the provision to the Service
Provider of comprehensive management services of the kind contemplated by this
Agreement.


     (f) Notwithstanding any provisions of this Agreement providing for
mandatory arbitration, PHC-SUB and the Service Provider acknowledge and agree
that PHC-SUB's remedy at law for any breach or attempted breach of the foregoing
provisions of this Section 5.4 will be inadequate and that PHC shall be entitled
to specific performance, injunction or other equitable relief in the event of
any such breach or attempted breach, in addition to any other remedies which
might be available at law or in equity.


     5.5.  CONTINUING PROFESSIONAL EDUCATION.


     The Service Provider shall ensure that each of its Service Provider
Employees participates in such continuing medical education activities as are

                                       17
<PAGE>
 
necessary for such physicians or other employees to remain current in their
respective specialties, including, but not limited to, the minimum continuing
medical education requirements imposed by applicable laws and policies of
applicable specialty boards.


     5.6.  CONTRACTS WITH SERVICE PROVIDER EMPLOYEES.


     Decisions regarding the addition of a New Service Provider Employee shall
be made by the Joint Policy Board pursuant to Section 6.1 hereof.  In addition,
the Service Provider shall use its best efforts to consult with PHC-SUB prior to
terminating the employment by the Service Provider of any Service Provider
Employee. The Service Provider shall also, during the term of this Agreement,
use its reasonable efforts to consult with PHC-SUB with regard to the terms and
conditions of contracts or other arrangements entered into between the Service
Provider and Service Provider Employees.  Notwithstanding the foregoing, all
decisions with respect to removing Service Provider Employees, and with respect
to the terms and conditions of contracts or other arrangements in connection
therewith, shall be made by the Service Provider, in its sole and absolute
discretion.


     5.7.  COOPERATION.


     The Service Provider shall cooperate in the obtaining and maintaining of
professional liability insurance coverage on Service Provider and Service
Provider Employees by assuring that it and its Service Provider Employees are
insurable, and by participating in an on-going risk management program.  The
Service Provider shall, and shall cause its Service Provider Employees to, use
their respective good faith efforts to exercise diligence in assisting PHC-SUB
to control costs and expenses of the Service Provider without sacrificing
professional standards or high quality patient care.  The Service Provider
shall, and shall require Service Provider Employees to, exercise due care to
ensure that, when being used by Service Provider Employees, medical equipment
utilized by the Service Provider is being used in a safe and efficient manner,
and shall timely report any unsafe or unsatisfactory equipment of which the
Service Provider, or any of its  Service Provider Employees, is aware.  The
Service Provider acknowledges and agrees that on execution of this Agreement,
PHC-SUB intends to implement its own policies and procedures, including, but not
limited to, policies and procedures regarding cash management and revenue
controls.  The implementation of such policies and procedures shall be subject
to the approval of the Service Provider, such approval not to be unreasonably
withheld.  These policies and procedures will be implemented as soon as
reasonably practicable after execution of this Agreement and may be revised or
amended by PHC-SUB from time to time thereafter during the term of this
Agreement, subject to the approval of the Service Provider.  Upon their
approval, the Service Provider agrees to cooperate with any such implementation,
revision, or enactment of PHC-SUB's policies and procedures. The Service
Provider also agrees to cooperate with, and participate in, any patient
satisfaction surveys and/or outcomes management surveys or programs instituted
or implemented by PHC-SUB, subject to approval by the Service Provider.


     5.8.  COVENANTS RELATING TO CREDIT AGREEMENT.


     (a) The Service Provider will cause to be reasonably promptly and duly

                                       18
<PAGE>
 
taken, executed, acknowledged, and delivered all such further acts, documents,

     (i) as may from time-to-time be necessary or as the secured party to the
Professional Service Provider Security Agreement may from time to time
reasonably request in order to carry out the intent and purposes of that
document and the transactions contemplated thereby, including all such actions
to establish, preserve, protect, and perfect the estate, right, title, and
interest to the Collateral (including Collateral acquired after the date hereof)
including first priority liens thereon; and


     (ii) as the secured party under the Professional Service Provider Security

date hereof.


     (b) The Service Provider will use its best efforts to assist PHC-SUB in
keeping accurate and complete records of its Receivables.


     (c)  At the request of the Secured Party, the Service Provider will appoint
the Secured Party as its attorney-in-fact for the purpose of collecting the
Service Provider's Receivables, including, without limitation, its Governmental
Receivables, consistent with any limitations provided by law and will cooperate
with the Secured Party in signing or otherwise providing notices to Third Party
Payors with respect to this agency.


     (d) Nothing in this Section 5.8 shall require the Service Provider to grant
any security interest in or lien on that portion of Service Provider Revenues
which have properly been distributed by PHC-SUB pursuant to this Agreement to
the Service Provider or at Service Provider's request to any person (other than
PHC-SUB).

     with any managed care contracting policies established by PHC-SUB or
     conflicts with any existing Managed Care Relationship of Service Provider,
     PHC-SUB or its affiliates, as determined by PHC-SUB in its reasonable

is a divided vote among the members of the Joint Policy Board, the Joint Policy
Board shall consider the matter for at least thirty (30) days from the date of

consensus. If such a unanimous consensus cannot be reached within thirty (30)
days, the Joint Policy Board, by majority vote, shall select any other PHC (or
PHC Affiliate) designated representative to another Joint Policy Board of
another PHC (or PHC Affiliate) affiliated practice, who shall consider the
matter in good faith and whose decision on such matter shall be final.

     6.3.  ANNUAL BUDGET AND BUSINESS PLAN.


     PHC-SUB shall be authorized to incur any operational, capital or other
expense approved by the Joint Policy Board pursuant to the Annual Budget.  PHC-

twelve (12) month period; (ii) the total expenses for the applicable budget
year, on an annualized basis, do not exceed the total amount budgeted for such
year by more than five percent (5%); or (iii) the expenditure is consented to by
the Joint Policy Board or the Service Provider.  Notwithstanding the foregoing,
PHC-SUB may exceed budgeted amounts in the event the increase in the expenditure
is reasonable and is the result of an event beyond the control of PHC-SUB (e.g.,
increases in tax rates or utility charges, Acts of God, strikes and labor
disputes) provided that PHC-SUB shall provide notice of such a situation to the
Service Provider.


     SECTION 7.  FINANCIAL ARRANGEMENTS.


     7.1.  PHC-SUB COMPENSATION.


     The Service Provider and PHC-SUB agree that the compensation described in

(5) years of this Agreement in the form attached to EXHIBIT 7.1 hereto.
Notwithstanding the foregoing, in the event (i) of death or permanent disability
of a Covered Physician, (ii) that a Covered Physician terminates his or her
affiliation with the Service Provider and pays the Liquidated Damages to PHC-SUB
pursuant to Section 5.4(b) or 5.4(c), the guarantee of payment of such
physician's proportionate share of the General Management Fee for the first five
(5) years of this Agreement shall be released; provided, however, that in such
event the Joint Policy Board shall agree to the addition of a New Service
Provider Employee if so requested by PHC-SUB.


          (b) PRACTICE DEVELOPMENT FEE.  As compensation for the provision by
     PHC-SUB of the Practice Development Services, PHC-SUB shall receive a

     exceeds (A) the aggregate Total Physician Revenue less (B) the aggregate
     physician New Service Provider Employees' allocable share of Common
     Operational Expenses (as defined in Exhibit 7.1) for physician New Service
     Provider Employees.  Notwithstanding the foregoing, unless otherwise agreed
     in writing between Service Provider and PHC-SUB at the time of approval by
     the Joint Policy Board of the hiring of a physician New Service Provider
     Employee, Service Provider shall not be entitled to all or any portion of
     the monthly credit under subsection (c) of this Section 7.1 for a physician
     New Service Provider Employee after 36 months employment by service
     Provider, if PHC-SUB delivers 90 days written notice to Service Provider of
     its intent to curtail all or any portion of such credit.


     7.2.  RECRUITMENT AND PRODUCTIVITY INCENTIVES.


     The Joint Policy Board, by a unanimous vote, may from time to time
establish performance and productivity incentives for the Service Provider and
the Service Provider Employees in addition to the financial arrangements set
forth in Section 7.1 hereof.  At the request of the Service Provider, PHC-SUB
will also advise and assist the Service Provider in establishing its own
productivity incentives for the Service Provider and the individual Service
Provider Employees.  The initial performance and productivity incentives for the
Service Provider shall be as set forth in EXHIBIT 7.2 hereto.


     7.3.  REVIEW OF FINANCIAL ARRANGEMENTS BY THE JOINT POLICY BOARD.


     The Joint Policy Board shall have the right to review PHC-SUB's
calculations of all payments, fees and expenses due by any party to any other
party or a third party under this Agreement.  In the event the Joint Policy
Board desires to review PHC-SUB's calculations or allocation of any such
payments, fees or expenses, the Joint Policy Board shall be provided, upon
reasonable notice to the PHC-SUB, the documents used in determining such amounts
(the "Compensation Documents").  Not later than fifteen (15) business days
following the delivery of the Compensation Documents to the Joint Policy Board,
the Joint Policy Board, pursuant to a majority determination and vote, may
furnish PHC-SUB with written notification of any dispute concerning any items
shown thereon or omitted therefrom, together with a detailed explanation in
support of the Joint Policy Board's position in respect thereof.  PHC-SUB and
the Joint Policy Board shall consult to resolve any dispute for a period of
fifteen (15) business days following such notification to PHC-SUB.  If such
fifteen (15) business day consultation period expires and the dispute has not
been fully resolved, the matter shall be referred to an independent public
accounting firm chosen by a unanimous vote of the Joint Policy Board (the
"Accountants"), which shall resolve the dispute and render its decision
(together with a brief explanation of the basis therefor) to the Joint Policy
Board and PHC-SUB not later than twenty (20) business days following submission
of the dispute to it; provided, however, that if the Joint Policy Board is
unable to agree by unanimous vote upon an independent public accounting firm,

                                       22
<PAGE>
 
then the Joint Policy Board, by majority vote, and PHC-SUB shall each choose an
independent public accounting firm and those firms shall appoint a third
independent public accounting firm to act as the Accountants. The decision of
such Accountants shall be a final determination of such amounts. The fees and
expenses of the Accountants shall be paid fifty percent (50%) by PHC-SUB and
fifty percent (50%) by the Service Provider.


     7.4.  CALCULATION OF PAYMENTS BASED ON ACCOUNTS RECEIVABLE.


     (a) Except for the first month of the term of this Agreement, on or before
the twentieth day of each month, PHC-SUB shall purchase the accounts receivable
of the Service Provider arising during the previous month, by payment of cash or
other readily available funds into the operating account of the Service Provider
to accelerate the cash flow to the Service Provider arising from such accounts
receivable.  The amount of monthly payment shall be an estimate based upon the
previous operating results of the Service Provider, shall take into account all
reasonable adjustments to the accounts receivable and the historical collection
rate on such receivables by the Service Provider, shall be discounted by three
percent (3%) with respect to those accounts receivable generated by or
attributable to (pursuant to the allocation of revenue by the Service Provider
as set forth in Table 1 to EXHIBIT 7.1 hereof) those physicians listed in
Section I of EXHIBIT 5.4(A) hereof, and shall be less all fees due PHC-SUB
pursuant to this Section 7 (the "Monthly Payment").


     (b) Adjustments to the Monthly Payments shall be made to reconcile actual
amounts due under this Section 7 within forty-five (45) days after the end of
each calendar quarter during the term of this Agreement.  At such quarterly
intervals, PHC-SUB shall determine the actual amounts due PHC-SUB pursuant to
this Section 7 for each such calendar quarter, with such amounts to be
calculated on an annualized basis for such quarters.  PHC-SUB shall notify the
Service Provider of the amount of payments, if any, due from one party to
another as a result of such adjustments within sixty (60) days of the end of
each calendar quarter.  If payment is due from one party to the other, such
amount shall be paid in full within ten (10) days of such notification of the
Service Provider; provided, however, that in the case such amounts are due PHC-
SUB on such calculations, PHC-SUB may, at its discretion, offset such amounts
due from the Service Provider against the Monthly Payment due the Service
Provider for succeeding calendar months.


     (c) Within one hundred twenty (120) days after the end of each calendar
year, PHC-SUB will determine the actual amounts due PHC-SUB pursuant to this
Section 7 for such calendar year (prorated for any calendar year for which this
Agreement has been in effect less than the entire year).


     If, after taking into account the Monthly Payments and any quarterly
adjustments for such calendar year, payment is due from one party to the other,
such amount shall be paid in full within ten (10) business days after such
calculations are made final; provided, however, that in the case amounts are due
PHC-SUB on such calculations, PHC-SUB may, at its discretion, offset such
amounts due from the Service Provider against the Monthly Payment due the
Service Provider for succeeding calendar months. This year-end reconciliation

                                       23
<PAGE>
 
shall include reconciliation of any amounts owed by one party to another with
respect to any expenses of any party, as set forth hereunder, paid by any other
party.


     (d) In order to secure the PHC-SUB loans used to purchase the accounts
receivable and to assure that PHC-SUB becomes owner of the accounts receivable
of the Service Provider, in case such purchase shall be ineffective for any
reason, the Service Provider is concurrently herewith entering into the
Professional Service Provider Security Agreement in the form attached as EXHIBIT
7.4(D) to grant a security interest in the accounts receivable to PHC-SUB.  In
addition, the Service Provider shall cooperate with PHC-SUB and execute all
necessary documents in connection with the pledge of such accounts receivable to
PHC-SUB or at PHC-SUB's option, its lenders.  All collections in respect of such
accounts receivable shall be deposited in a Service Provider bank account at a
bank designated by PHC-SUB.  To the extent the Service Provider comes into
possession of any payments in respect of such accounts receivable, the Service
Provider shall transfer such payments to PHC-SUB for deposit in bank accounts
designated by PHC-SUB and as further security for PHC-SUB advances.


     (e) During the first month of the term of this Agreement, PHC-SUB shall
provide to Service Provider an initial salary funding of up to $250,000 to the
extent necessary (together with Service Provider's available funds) for Service
Provider to pay its Service Provider Employees an aggregate of up to $350,000 in
compensation during the first 30 days of the term of this Agreement (the
"Initial Salary Funding").  The Initial Salary Funding shall be included as an
Operational Expense for the month immediately preceding termination of this
Agreement only in the event this Agreement is terminated pursuant to Section
8.2(c)(iv) hereof.


     7.5.  NEW ANCILLARY SERVICES.


     The Service Provider and PHC-SUB jointly acknowledge that a primary
motivation for their entering into an affiliation is to expand the Service
Provider and develop New Ancillary Services for the Service Provider.  In
consultation with the Service Provider, PHC-SUB will identify and evaluate such
New Ancillary Service opportunities, and, consistent with and subject to all
applicable state and federal laws and regulations, the Service Provider and PHC-
SUB will mutually agree upon and determine the financial arrangements with
respect to the New Ancillary Service Revenue and New Ancillary Service Expenses
related thereto.  The Service Provider agrees and shall require all Covered
Physicians to agree that, subject to all applicable state and federal laws
regulations, the Service Provider and such employee shall develop, invest or
participate in New Ancillary Services and facilities only in partnership or
other business arrangement with PHC-SUB.

including, without limitation, PHC-SUB's provision to the Service Provider of

that, upon termination or expiration of this Agreement: (a) PHC-SUB shall retain
all right, title and interest in and to all of its proprietary software and
systems, including software and systems licensed by PHC-SUB from others, used in

right to license such software and systems from PHC-SUB on commercially
reasonable terms for a one (1) year period, and (b) the Service Provider shall
be responsible for obtaining its own software and systems to take over the
General Management Services from PHC-SUB.  Upon expiration or termination of the
Agreement (except pursuant to Section 8.2(c)(i), (ii) or (iii)) and payment of
all amounts due to the Service Provider hereunder through the date of expiration
or termination, the Service Provider shall fully and completely assign to PHC-

expiration or earlier termination of this Agreement, neither party shall have
any further obligation hereunder with the exception of obligations accruing
prior to the date of such expiration or earlier termination and obligations,

                                       28
<PAGE>
 
Service Provider. The funds for settlement of such financial arrangements shall
be disbursed on the closing date of the repurchase of assets provided for in

      8.4  REPURCHASE OF ASSETS.


     (a) Upon termination of this Agreement pursuant to Section 8.1 or 8.2
hereof, other than pursuant to Section 8.2(a)(v) or 8.2(c)(iv) or 8.2(c)(v), the
Service Provider shall purchase from PHC-SUB those tangible and intangible
assets (including the name "Parkcrest Surgical Associates, Inc.") owned by PHC-
SUB that primarily relate to the operation of the Service Provider, including
all FF&E and all real estate ("Real Estate") owned by PHC-SUB and associated
primarily with the operation of the Service Provider (collectively the
"Repurchase Assets") at a purchase price (the "Buyout Amount") as set forth in
EXHIBIT 8.4(A) attached hereto.  Upon termination of this Agreement pursuant to
Section 8.2(a)(v) or 8.2(c)(iv) or 8.2(c)(v) hereof, the Service Provider shall
purchase from PHC-SUB the Repurchase Assets for the following Buyout Amount:


          All the cash and all the shares of PHC "Prime Common Stock" (or Common
          Stock, if the Prime Common Stock has converted into Common Stock as of
          the date of termination of the Agreement) paid by PHC in connection
          with the Merger Agreement (the "Total Merger Consideration") less the
          aggregate amount of any Liquidated Damages previously paid to PHC-SUB
          by Service Provider Employees pursuant to Section 5.4 and EXHIBIT 5.4
          hereof, adjusted in cash for any increase or decrease in the book
          value of the FF&E and the Real Estate (on PHC's books and records)
          from the Effective Date until the date of termination (the "Tangible
          Asset Cash Adjustment").


     (b) In addition to the payment of the Buyout Amount as set forth in Section
8.4(a), upon termination of this Agreement, the Service Provider shall pay all
debt and assume without recourse against PHC-SUB all contracts, payables and
leases which are obligations of PHC-SUB and which relate exclusively to the
performance of its obligations under this Agreement or the properties subleased
by PHC-SUB, other than such contracts, payables and leases that are between the
Service Provider and PHC-SUB or its affiliates.  The Buyout Amount shall be
reduced by the amount of debt and liabilities of PHC-SUB assumed by the Service
Provider and by any payment PHC-SUB has failed to make under this Agreement
(other than any such payments constituting all or a portion of the Service
Provider Lost Income Amount).  The Service Provider and any physician
shareholder of the Service Provider shall execute such documents as may be
required to assume the liabilities set forth in this Section 8.4 and to remove
or indemnify PHC-SUB to its reasonable satisfaction from any liability with
respect to such repurchased assets and with respect to any property leased or
subleased by PHC-SUB. The closing date for the repurchase shall be determined by
the Service Provider, but shall in no event occur later than 60 days from the
date of the notice of termination. The termination of this Agreement shall

                                       29
<PAGE>
 
become effective upon the closing of the sale of the assets and the Service
Provider and the Service Provider Employees shall be released from the
restrictive covenants as and to the extent set forth in Section 8.4(c) on the
closing date. PHC-SUB shall have the right, in its sole and absolute discretion,
to waive the repurchase requirements of the Service Provider, in which event,
the termination of this Agreement shall become effective upon the execution and
delivery of such waiver.


     (c) Release from Certain Restrictive Covenants.


          (i) Upon termination of this Agreement pursuant to Sections 8.2(a),
     8.2(b), 8.2(c)(iv), 8.2(c)(v) or 8.2(e), if the Service Provider remits the
     Buyout Amount to PHC-Sub in accordance with this Section 8.4 within 60 days
     after determination of such Buyout Amount, the Service Provider and the
     Service Provider Employees shall be released from the restrictive covenants
     of Sections 5.4(a) and 5.4(d) but not 5.4(e).


          (ii) Upon termination of this Agreement pursuant to Sections
     8.2(c)(i), 8.2(c)(ii), 8.2(c)(iii), or 8.2(d), if the Service Provider
     remits the Buyout Amount to PHC-Sub in accordance with this Section 8.4
     within 60 days after determination of such Buyout Amount, the Service
     Provider and the Service Provider Employees shall be released from the
     restrictive covenants of Sections 5.4(a), 5.4(d) and 5.4(e).


          (iii)  If the Service Provider does not remit the Buyout Amount to
     PHC-SUB in accordance with Section 8.4(a) hereof within 60 days after
     determination of such Buyout Amount, all the provisions of Section 5.4 of
     this Agreement shall survive in their entirety for a period of two years
     following the date of termination of this Agreement.

TERMINATION.


     In taking action to terminate this Agreement the parties shall comply with
the following procedures:

     the expiration of any cure periods.


          (b) The taking by the Practice of any action with respect to
     termination of this Agreement shall require the affirmative vote of the
     holders of two-thirds of the equity interests of the shareholders of the
     Practice.

perform this Agreement and all agreements executed and delivered by it pursuant

Certificate of Incorporation, its Bylaws or otherwise to authorize the
execution, delivery and performance of this Agreement and such related
documents.  The execution and delivery of this Agreement does not and, subject
to the consummation of the transactions contemplated hereby, will not, violate
any provisions of the Articles or Certificate of Incorporation or Bylaws of the
Service Provider or any provisions of, or result in the acceleration of, any
obligation under any mortgage, lien, lease, agreement, instrument, order,
arbitration award, judgment or decree, to which the Service Provider is a party,

the Service Provider and constitutes the legal, valid and binding obligation of
the Service Provider, enforceable in accordance with its terms.

     (a) There is no action, suit, or proceeding pending against, or to the best
knowledge of the Service Provider threatened against or affecting, the Service
Provider or any Service Provider Employee before any court or arbitrator or any

the validity of the Professional Service Provider Security Agreement.


     (b) There is no pending investigation of the Service Provider or any of its
members, partners, or Service Provider Employees, or any one or more of them, as
the case may be, by HCFA or any other governmental authority, which

<PAGE>
 
no criminal, civil or administrative action, audit, or investigation by a fiscal
intermediary or by or on behalf of any governmental authority exists against the
Service Provider or any of its members, partners, or Service Provider Employees,
or any one or more of them, as the case may be, or to the best knowledge of the
Service Provider, is threatened with respect to such persons or any one of them
which could reasonably be expected to materially and adversely affect the right
of such person or persons to receive Medicare, Medicaid, CHAMPUS or CHAMPVA
reimbursement to which such person or persons would otherwise be entitled, or
right to participate in the Medicare, Medicaid, CHAMPUS or CHAMPVA programs, or
otherwise have a Material Adverse Effect on the receipt of Medicare, Medicaid,
CHAMPUS or CHAMPVA reimbursement by such person or persons.


     (c) To the best knowledge of the Service Provider, neither the Service
Provider nor any of its members, partners or Service Provider Employees or any
one or more of them, as the case may be, is subject to any pending but
unassessed Medicare, Medicaid, CHAMPUS or CHAMPVA claim payment adjustments,
except to the extent that such person or persons is contesting such assessment
in good faith by appropriate proceedings diligently pursued and has established
or caused to be established by his or her employer, limited liability company,
or partnership, as the case may be, adequate reserves for such adjustments in
accordance with GAAP.


     9.5.  NO DEFAULT.


     Neither the Service Provider nor its members, partners, Service Provider
Employees, or any one or more of them has received notification from any
governmental authority that any such governmental authority has taken or intends

certificate, accreditation or permit of such person to operate a healthcare
facility or to participate under Medicare, Medicaid, CHAMPUS or CHAMPVA.


     9.6.  THIRD PARTY REIMBURSEMENT.


     If the Service Provider or any Service Provider Employee is being audited
or has been audited by Medicare, Medicaid, CHAMPUS or CHAMPVA or similar
governmental Third Party Payors:


          (a) none of such audits provides for adjustments in reimbursable costs
     or assets, claims for reimbursement or repayment by the Service Provider or
     any Service Provider Employee of costs and/or payments theretofore made by
     such governmental Third Party Payor that, if adversely determined, could
     reasonably be expected to have or result in a Material Adverse Effect; and


          (b) neither the Service Provider nor any Service Provider Employee has
     had requests or assertions of claims for reimbursement or repayment by it,
     or him or her, as the case may be, of costs and/or payments heretofore made
     by any other Third Party Payor that, if adversely determined, could
     reasonably be expected to have or result in a Material Adverse Effect.

     10.1.  INSURANCE  MAINTAINED BY THE SERVICE PROVIDER.

termination of this Agreement for any reason so as to cover any and all
professional liability claims or causes of action caused or asserted to have
been caused as a result of the performance of medical services by the Service
Provider and its employees or agents during the term of this Agreement.  The
Service Provider shall provide, or shall arrange for the provision of, and shall
maintain throughout the entire term of this Agreement, workers' compensation
insurance coverage on the Service Provider and each of its employees and agents
in the amounts required by law.  The Service Provider shall provide to PHC-SUB
written documentation evidencing such insurance coverage.


     10.2.  INSURANCE MAINTAINED BY PHC-SUB.

shall be an Operational Expense.  If so requested by the Service Provider,
PHC-SUB shall provide written documentation evidencing such insurance coverage.


     10.3.  CONTINUING LIABILITY INSURANCE COVERAGE.


     The Service Provider shall obtain, or shall ensure that each Service

                                       33
<PAGE>
 
Provider Employee or agent obtains, continuing liability insurance coverage
under either a "tail policy" or a "prior acts policy," with the same limits and
deductibles as the insurance coverage provided pursuant to Section 10.1, for
each of the Service Provider's employees and agents upon the termination of such
employee's or agent's relationship with the Service Provider for any reason.
The Service Provider shall provide to PHC-SUB written documentation evidencing
such insurance coverage.  In the event the Service Provider does not obtain such
continuing liability insurance coverage, PHC-SUB may do so and the cost of such
coverage shall be included as an Operational Expense.  The Service Provider's
obligation to obtain, or ensure that each of the Service Provider's employees
and agents obtains, such continuing liability insurance coverage shall survive
the termination of this Agreement for any Service Provider employee or agent
associated with the Service Provider during the term of this Agreement.


     10.4.  INDEMNIFICATION.


     PHC-SUB hereby agrees to  indemnify, hold harmless and defend the Service
Provider from and against any and all liability, loss, damages, claims, causes
of action and expenses associated therewith (including reasonable attorneys'
fees) caused or asserted to have been caused, directly or indirectly, by or as a
result of the performance of management services by PHC-SUB, its employees or
agents during the term hereof.  The Service Provider hereby agrees to indemnify,
hold harmless and defend PHC-SUB from and against any and all liability, loss,
damages, claims, causes of action and expenses associated therewith (including
reasonable attorneys' fees) caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of medical services by the
Service Provider and its employees or agents during the term hereof.  The
provisions of this Section 10.4 shall survive the expiration or earlier
termination of this Agreement.  Each party, if so requested, shall provide the
other with written documentation evidencing notification of such party's
insurance carrier of the provisions of this Section 10.4.  A party seeking
indemnification pursuant to this Section 10.4 shall promptly notify the other
party by specifying the basis on which indemnification is sought and the amount
of asserted losses as such information becomes known to such party.


     10.5.  KEY PERSON INSURANCE.


     The Service Provider agrees, and shall cause its Service Provider Employees
to agree, that PHC-SUB may obtain, at its sole expense and for its sole benefit,
"key person" life and/or disability insurance policies on any or all Service
Provider Employees.  Neither the Service Provider nor any Service Provider
Employee shall have any right, title or interest, in or to the proceeds of any
such insurance policies.  The Service Provider shall cause its Service Provider
Employees to cooperate with PHC-SUB, as reasonably requested by PHC-SUB from
time to time, in obtaining any such insurance policies, including, but not
limited to, causing such Service Provider Employees to submit to such physical
examinations and providing such information relating to insurability as PHC-SUB
may reasonably request from time to time.

     SECTION 11.  COMPLIANCE WITH REGULATIONS.


     11.1.  SUBCONTRACTS.


     Pursuant to Title 42 of the United States Code and applicable rules and
regulations thereunder, until the expiration of four (4) years after termination
of this Agreement, PHC-SUB shall make available, upon appropriate written
request by the Secretary of the United States Department of Health and Human
Services or the Comptroller General of the United States General Accounting
Office, or any of their duly authorized representatives, a copy of this
Agreement and such books, documents and records as are necessary to certify the
nature and extent of the costs of the services provided by PHC-SUB under this
Agreement.  PHC-SUB further agrees that if it carries out any of its duties
under this Agreement through a subcontract with a value or cost of Ten Thousand
Dollars ($10,000.00) or more over a twelve (12) month period with a related
organization, such subcontract shall contain a clause to the effect that until
the expiration of four (4) years after the furnishing of such services pursuant
to such subcontract, the related organization shall make available, upon
appropriate written request by the Secretary of the United States Department of
Health and Human Services or the Comptroller General of the United States
General Accounting Office, or any of their duly authorized representatives, a
copy of such subcontract and such books, documents and records of such
organization as are necessary to verify the nature and extent of such costs.
Disclosure pursuant to this Section shall not be construed as a waiver of any
other legal right to which PHC-SUB or the Service Provider may be entitled under
law or regulation.


     SECTION 12.  RELATIONSHIP OF THE PARTIES.


     12.1.  INDEPENDENT CONTRACTOR STATUS.


     (a) It is acknowledged and agreed that the Service Provider and PHC-SUB are
at all times acting and performing hereunder as independent contractors.  PHC-
SUB shall neither have nor exercise any control or direction over the methods by
which the Service Provider and Service Provider Employees practice medicine.
PHC-SUB shall not, by entering into and performing its obligations under this
Agreement, become liable for any of the existing obligations, liabilities or
debts of the Service Provider unless otherwise specifically provided for under
the terms of this Agreement or the Purchase Agreement.  In its management role,
PHC-SUB will have only an obligation to exercise reasonable care in the
performance of the management services.  PHC-SUB shall have no liability
whatsoever for damages suffered on account of the willful misconduct or
negligence of any employee, agent or independent contractor of the Service
Provider.  Each party hereto shall be solely responsible for compliance with all
state and federal laws pertaining to employment taxes, income withholding,
unemployment compensation contributions and other employment related statutes
regarding their respective employees, agents and servants.


     (b) In the event any state or federal laws or regulations, now existing or
enacted or promulgated after the date hereof, are interpreted by judicial
decision, a regulatory agency or legal counsel in such a manner as to indicate

                                       35
<PAGE>
 
that this Agreement or any provision hereof may be in violation of such laws or
regulations, the Service Provider and PHC-SUB shall amend this Agreement as
necessary to preserve the underlying economic and financial arrangements between
the Practice and PHC-SUB and without substantial economic detriment to either
party. To the extent any act or service required of PHC-SUB in this Agreement
should be construed or deemed, by any governmental authority, agency or court,
to constitute the unauthorized practice of medicine, the performance of said act
or service by PHC-SUB shall be deemed waived and forever unenforceable and the
provisions of this Section 12.1(b) shall be applicable. Neither party shall
claim or assert illegality as a defense to the enforcement of this Agreement or
any provision hereof; instead, any such purported illegality shall be resolved
pursuant to the terms of this Section 12.1(b).


     12.2.  REFERRAL ARRANGEMENTS.


     The parties hereby acknowledge and agree that no benefits to the Service
Provider hereunder require or are in any way contingent upon the admission,
recommendation, referral or any other arrangement for the provision of any item
or service offered by PHC-SUB or any of its Affiliates, to any patients of the
Service Provider, the Service Provider's employees or agents.


     SECTION 13.  CONFIDENTIAL INFORMATION AND INSPECTION RIGHTS.


     (a) At no time during the term of this Agreement or the five (5) year
period after any termination or expiration of this Agreement for any reason
shall Service Provider or any of its employees or agents, on the one hand, or
PHC-SUB or any of its employees or agents, on the other hand, disclose to
anyone, other than its attorneys, accountants or other  financial advisors, the
material terms of this Agreement or any other written agreement between the
parties hereto, or any confidential or secret information concerning (a) the
business, affairs or operations, (b) any trade secrets, new product
developments, special or unique processes or methods, or (c) any marketing,
sales, advertising or other concepts or plans, of PHC-SUB or any of its
Affiliates, on the one hand, or of the Service Provider, its Service Provider
Employees, subsidiaries or Affiliates, on the other hand.


         The covenants contained in this Section 13 shall not apply to any
information which (i) was already known to such party at the time of receipt
thereof, (ii) was readily available to the general public at the time of receipt
thereof, (iii) subsequently becomes known to the general public through no fault
or omission on the part of such party, (iv) is subsequently disclosed by a third
party which has the bona fide right to make such disclosure, or (v) is required
to be disclosed by law or governmental agency.


         Each of PHC-SUB and the Service Provider hereby acknowledges that if
it or any of its employees or agents engage in activities within the limitations
of this Section 13, money damages shall be an inadequate remedy, and each of
PHC-SUB and the Service Provider agree that the nonbreaching party shall be
entitled to obtain, in addition to any other remedy provided by law or equity,
an injunction against the violation of breaching party's obligation to the
nonbreaching party hereunder.

                                       36
<PAGE>
 
     (b) The Service Provider shall have reasonable access to the files and
records relating to such revenue and expenses and the overall operation of the
Service Provider. The Service Provider, at its expense, may have its accountants
review such records, at reasonable intervals, to confirm the accuracy of such
records and fees paid by the Service Provider to PHC-SUB under this Agreement.


     SECTION 14.  ARBITRATION.


     (a) Except as contemplated by Section 5.4(f) hereof, any and all disputes
arising out of or in connection with the negotiation, execution, interpretation,
performance, nonperformance or arbitrability of this Agreement shall be solely
and finally settled by arbitration, which shall be conducted in St. Louis,
Missouri, or at such other location as the parties may agree in writing. The
arbitrator shall conduct the proceedings in accordance with the Commercial
Arbitration Rules of the American Arbitration Association, as supplemented by
the American Arbitration Association's Supplementary Procedures for Large,
Complex Disputes (the "Rules"). The arbitration proceeding shall be initiated in
accordance with the Rules. Except as contemplated by Section 5.4(f) hereof, the
parties hereby renounce all recourse to litigation and agree that any
arbitration award shall be final and subject to no judicial review. The
arbitration shall be conducted before three arbitrators, chosen in accordance
with the Rules. The arbitrator(s) shall decide the issues submitted in
accordance with (i) the language and commercial purposes of this Agreement; and
(ii) what is just and equitable under the circumstances, provided that all
substantive questions of law (excluding principles of conflicts of laws) shall
be determined under the laws of the State of Missouri. Except as contemplated by
Section 5.4(f) hereof, all damage awards related to a breach of this Agreement
shall be monetary and based on the lost income of the nonbreaching party as the
result of the breach without giving effect to any consequential or punitive
damages. In addition, the arbitrator shall decide certain termination matters as
provided in Sections 8.2 (b), (d) and (e). Nothing in this Article 14 shall
require arbitration of matters relating to termination of this Agreement
pursuant to Section 8.2(a) or 8.2(c).

     (b) The parties agree to facilitate the arbitration by: (i) making
available to one another and to the arbitrator for examination, inspection and
extraction all documents, books, records and personnel under their control
determined by the arbitrator to be relevant to the dispute (ii) conducting
arbitration hearings to the greatest extent possible on successive days; and
(iii) observing strictly the time periods established by the Rules, or by the
arbitrator, for submission of evidence or briefs.

     (c) Judgment on the award of the arbitrator may be entered in any court
having jurisdiction over the party against which enforcement of the award is
being sought. All deposits and other costs (other than fees of counsel) incurred
in conducting the arbitration shall be borne equally by the parties. Each party
shall be solely responsible for its own attorney's fees incurred in connection
with the arbitration.

     (d) This section shall survive completion or termination of this Agreement,
and shall be specifically enforceable in any court of competent jurisdiction.
In no event shall a demand for arbitration be made after the date when any
applicable statute of limitations, or period for claims

                                       37
<PAGE>
 
under the Agreement, would bar institution of a legal or equitable proceeding
based on such dispute or subject matter in question.


     SECTION 15.  MISCELLANEOUS.


     15.1.  ASSIGNMENT AND DELEGATION.


     PHC-SUB shall have the right to assign its rights hereunder to any
Affiliate of PHC-SUB and to any lending institution, for security purposes or as
collateral, from which PHC, PHC-SUB or such person, firm or corporation obtains
financing.  Except as set forth in this Section 15.1, neither PHC-SUB nor the
Service Provider shall have the right to assign their respective rights and
obligations hereunder without the written consent  of the other party.  The
Service Provider may not delegate any of its duties hereunder, except as
expressly contemplated herein; however, PHC-SUB  may delegate some or all of its
duties hereunder to the extent it concludes, in its sole discretion, that such
delegation is in the mutual interest of the parties hereto.


     15.2.  OTHER CONTRACTUAL ARRANGEMENTS.


     The parties acknowledge and agree that they have been advised and consent
to the fact that PHC-SUB or its Affiliates (i) may have, prior to the date of
this Agreement, discussed proposals with respect to, or (ii) may, from time to
time hereafter enter agreements with one or more Service Provider Employees  to
provide consulting, medical direction, advisory or similar services relating to
activities of PHC-SUB or its Affiliates in clinical areas.  The parties agree
that such agreements, if any, shall be entered into at the sole discretion of
the parties thereto and subject to such terms and conditions  to which such
parties may agree, and any compensation payable to or by PHC-SUB, on the one
hand, and such Service Provider Employees, on the other hand, shall not
constitute Service Provider Revenues and shall otherwise not be subject to the
provisions of this Agreement.  Each current physician shareholder of the Service
Provider by his or her execution of this Agreement as provided on the signature
page hereof, agrees that neither the negotiation nor the entry into any
agreement or arrangement of a type described in this Section 15.2 shall
constitute a breach of fiduciary or other duty owed by any such physician to
another or to any Service Provider Employee, or by PHC-SUB, to the Service
Provider or any such physician or Service Provider Employee.


     15.3.  NOTICES.

the PHC-SUB will make under this Agreement to maintain, develop and expand the

I.  COVERED PHYSICIANS WHO ARE ORIGINAL PHYSICIAN SERVICE PROVIDER
    --------------------------------------------------------------
    EMPLOYEES
    ---------

      A.  At the end of the seventh year of the Agreement, the physician
will be granted the following:


          Options to purchase 200 shares of common stock of PHC at the
          then-current share price at the end of year seven for each $1,000
          of management fees generated by the physician during year seven
          of the Agreement.  Twenty-five percent (25%) of the options
          earned in year seven would vest annually at the end of each of
          the four years after the year in which they were earned (i.e.,
          the end of years eight through eleven).


      B.  At the end of year eleven of the Agreement, the physician will be
granted options to purchase the following number of shares of the common
stock of PHC at the then-current share price:


          Three (3) times the management fees generated by the physician in
          year eleven divided by the current market price per share of PHC
          Stock at the end of year eleven (e.g., if the Physician generates
          $100,000 in management fees in year eleven and the price per
          share of PHC Stock at the end of year eleven is $30, then the
          Physician would be granted options to purchase [3 x 100,000]/30 
          = 10,000 shares of PHC Stock).  Twenty-five percent (25%) of the
          options earned in year eleven would vest annually at the end of
          each of the four years after the year in which they were earned
          (i.e., the end of years twelve through fifteen).

II.  PHYSICIANS JOINING THE PRACTICE AFTER THE EFFECTIVE DATE
     --------------------------------------------------------

     At the end of the fourth year after the new physician joins the practice,
the physician will be granted options to acquire the following number of shares
of PHC Stock:


          200 shares per $1,000 of management fees generated by the
          physician in year four at the then-current share price at the end
          of year four.  The options earned in year four would vest pro-
          rata annually at the end of each of years five through ten after
          the physician joins the practice.

other physician's PHYSICIAN'S INITIAL GENERAL MANAGEMENT FEE.  Service Provider

                                                                       --------
                    , 1997 (the "PM Agreement").  This Guaranty is executed and
- -------------------
delivered pursuant to Section 7.1(a) of the PM Agreement.


     1.02  Statement of Agreement.  For and in consideration of the sum of
           ----------------------                                         
$10.00 and other valuable consideration, the receipt and sufficiency of which
are hereby acknowledged by Guarantor, and for the purpose of seeking to induce
PHC-SUB to enter into the PM Agreement,  Guarantor does hereby make the
following guarantees to and agreements with PHC-SUB.


                            ARTICLE II - GUARANTEES
                            -----------------------


     2.01  Guaranty of Payment.  Except as limited by Sections 2.02 and 4.05
           -------------------                                              
below, (a) Guarantor does hereby unconditionally guarantee to PHC-SUB the full
and prompt payment when due of an amount not to exceed up to $[PHYSICIAN'S
INITIAL GENERAL MANAGEMENT FEE] per year (the "Fee Amount"), which Fee Amount
represents Guarantor's share of the General Management Fee payable by the
Service Provider to PHC-SUB pursuant to Section 7.1(a) of the PM Agreement (the
"General Management Fee") when due, during the five (5) year period following
the date hereof; (b) Guarantor does hereby agree that if Service Provider does
not pay Guarantor's share of the General Management Fee as required by the PM
Agreement, Guarantor will immediately make such payments and (c) Guarantor
further agrees to pay PHC-SUB all expenses (including, without limitation,
reasonable attorneys' fees actually paid) paid by  PHC-SUB in endeavoring to
collect all or any portion of the indebtedness evidenced by the General
Management Fee, to enforce any other obligations guaranteed hereby, or to

     2.02  Limitations on Guaranty.  Notwithstanding anything to the contrary in
           -----------------------                                             
this Guaranty, (a) PHC-SUB shall not be entitled to enforce its rights under
this Guaranty against Guarantor if Guarantor is then generating sufficient net
revenues for Service Provider to pay Guarantor's share of the General Management
Fee equal to the Fee Amount, or Service Provider otherwise causes to be paid the
entire General Management Fee; and (b) PHC-SUB shall not be entitled to enforce
its rights under this Guaranty as to any portion of the General Management Fees
first becoming due after the date on which Guarantor dies or becomes
"Permanently Disabled" or if this Guaranty is terminated pursuant to Section
4.05 hereof.  For the purpose of this Agreement, Permanent Disability or
Permanently Disabled shall have the same meaning as is given to the term in the
permanent disability policy maintained by the Guarantor for himself or herself
on the date of such permanent disability, provided the physician has such a
policy and provided the policy is a commercially reasonable one, or, in the
event no such policy exists, then permanent disability shall be determined by an
independent physician mutually agreed upon between Guarantor (or his/her
representative, if he/she is unable) and PHC-SUB.


                    ARTICLE III - AGREEMENTS AND WARRANTIES
                    ---------------------------------------


     3.01  Consents.  Guarantor hereby consents and agrees that PHC-SUB may at
           --------                                                           
any time, and from time to time, without notice to or further consent from
Guarantor, either with or without consideration: release and surrender any
property or other security of any kind or nature whatsoever hereafter held by it
or by any person or entity on its behalf or for its account, securing any
indebtedness or liability hereby guaranteed, if any; extend or renew the time
for payment of the General Management Fee for any period; grant releases,
compromises and indulgences with respect to the General Management Fee to any
other persons or entities now or hereafter liable thereunder or hereunder;
release any other guarantor or endorser of or other person or entity liable for
the General Management Fee; or take or fail to take any action of any type
whatsoever.  No such action which PHC-SUB shall take or fail to take in
connection with the General Management Fee, nor any course of dealing with the
Service Provider or any other person, shall limit, impair or release Guarantor's
obligations hereunder, affect this Guaranty in any way or afford Guarantor any
recourse against PHC-SUB.  Nothing contained in this section shall be construed
to require PHC-SUB to take or refrain from taking any action referred to herein.


     3.02  Waiver.  Guarantor hereby expressly waives any right of contribution
           ------                                                              
from or indemnity against the Service Provider, whether at law or in equity,
arising from any payments made by Guarantor pursuant to the terms of this
Guaranty, and Guarantor acknowledges that Guarantor has no right whatsoever to
proceed against the Service Provider for reimbursement of any such payments.


     3.03  Waiver of Defenses.  Guarantor hereby waives and agrees not to assert
           ------------------                                                   
or take advantage of any defense based upon: (a) any incapacity or lack of
authority (b) any failure of PHC-SUB to commence an action against the Service
Provider or any other person or entity (including, without limitation, other
guarantors, if any), or to file or enforce a claim against the estate (either in
administration, bankruptcy, or any other proceeding) of the Service Provider or
any other person or entity, whether or not demand is made upon PHC-SUB to file
or enforce such claim; (c) any lack of acceptance or notice of acceptance of
this Guaranty by PHC-SUB; (d) any

                                       53
<PAGE>
 
lack of presentment, demand, protest, or notice of demand, protest or nonpayment
with respect to any indebtedness or obligations under the PM Agreement; (e) any
invalidity, irregularity or unenforceability in part, of the PM Agreement; and
(f) any action, occurrence, event or matter consented to by Guarantor under
Section 3.01 hereof, under any other provision hereof, or otherwise.


     3.04  Liability of Guarantor.  This is a guaranty of payment and
           ----------------------                                    
performance and not of collection.  The liability of Guarantor under this
Guaranty shall be direct and immediate and not conditional or contingent upon
the pursuit of any remedies against the Service Provider or any other person
(including, without limitation, other guarantors, if any).  Guarantor waives any
right to require that an action be brought against the Service Provider or any
other person or to require that resort be had to any collateral or to any
balance of any deposit account or credit on the books of PHC-SUB in favor of the
Service Provider or any other person.  In the event that, on account of the
Bankruptcy Reform Act of 1978, as amended, or any other debtor relief law
(whether statutory, common law, case law or otherwise) of any jurisdiction
whatsoever, now or hereafter in effect, which may be or become applicable, the
Service Provider shall be relieved of or fail to incur any debt, obligation or
liability as provided in the PM Agreement, Guarantor shall nevertheless be fully
liable therefor.  In the event of a default under the PM Agreement, PHC-SUB
shall have the  right to enforce its rights, powers and remedies thereunder or
hereunder, in any order, and all rights, powers and remedies available to PHC-
SUB in such event shall be nonexclusive and cumulative of all other rights,
powers and remedies provided thereunder or hereunder or by law or in equity.  If
the indebtedness guaranteed hereby is partially paid by reason of the election
of PHC-SUB to pursue any of the remedies available to PHC-SUB, or is otherwise
partially paid, this Guaranty shall nevertheless remain in full force and
effect, and Guarantor shall remain liable for the entire remaining unpaid
balance of the indebtedness guaranteed hereby, even though any rights which
Guarantor may have against the Service Provider may be destroyed or diminished
by the exercise of any such remedy.


                        ARTICLE IV - GENERAL CONDITIONS
                        -------------------------------


     4.01  Irrevocability and Revival.  Subject to the termination provisions
           --------------------------                                        
contained in Section 4.05, this Guaranty shall be irrevocable by Guarantor and
shall remain in effect until all indebtedness guaranteed hereby has been
completely repaid.  This Guaranty shall continue to be effective or be revived
and reinstated, as the case may be, in the event that any payment received by
PHC-SUB of any of the indebtedness guaranteed hereby is returned or rescinded by
reason of any present or future federal, state or other law or regulation
relating to bankruptcy, insolvency or other relief of debtors or for any other
reason.


     4.02  Limit of Validity.  If from any circumstances whatsoever fulfillment
           -----------------                                                   
of any provisions of this Guaranty, at the time performance of such provision
shall be due, shall involve transcending the limit of validity presently
prescribed by any applicable usury statute or any other applicable law, with
regard to obligations of like character and amount, then ipso facto the
                                                         ---- -----    
obligation to be fulfilled shall be reduced to the limit of such validity, so
that in no event shall any exaction be possible under this Guaranty that is in
excess of the current limit of such validity, but such obligation shall be
fulfilled to the limit of such validity.  The provisions of this section shall

                                       54
<PAGE>
 
control every other provision of this Guaranty.


     4.03  Applicable Law.  This Guaranty shall be interpreted, construed and

           -------------                                                  
obligation of Guarantor can be released or waived by PHC-SUB or any officer or

the guarantying of the General Management Fee by Guarantor and supersedes
entirely any and all prior written or oral agreements with respect thereto; and
Guarantor and PHC-SUB acknowledge that there are no contemporaneous oral
agreements with respect to the subject matter hereof.


     4.05  Termination.  This Guaranty shall terminate on the later of (a) the
           -----------                                                        
fifth anniversary of the date hereof or (b) the date that Guarantor's Fee Amount

require the return of any PHC Stock.

termination of this Agreement of (x) all the shares of PHC Prime Common Stock
(or PHC Common Stock, if the PHC Prime Common Stock has converted into PHC

pursuant to the Merger Agreement, minus (y) those shares of PHC stock delivered

          (ii) if this Agreement is terminated pursuant to Section 8.2(c)(i) or
(ii), or 8.2(d) or 8.2(e), the PHC Stock Value will be reduced by (x) all

otherwise paid to PHC-SUB); and
 

          (iv) the PHC Stock Value, as adjusted pursuant to items (ii) and (iii)
above, shall be multiplied by the following amounts based on the date of
termination of this Agreement to determine the Buyout Amount:

Common Stock as of the date of termination of this Agreement) at fair market
value.


     B.  TERMINATION AFTER FIRST FIVE YEARS.  If this Agreement is terminated
after the first five years of this Agreement, the Buyout Amount shall be:

          (i) All the PHC Prime Common Stock paid by PHC to the Shareholders
pursuant to the Merger Agreement (the "Merger Agreement Consideration"), less
the number of shares of PHC Prime Common Stock equal to (based on an assumed
$4.00 value per share): (A) the total General Management Fees paid by the
Service Provider prior to such termination; (B) minus the Service Provider Lost
Income Amount (if applicable); (C) plus the PHC-SUB Lost Income Amount (if
applicable); plus or minus (as applicable) the Tangible Asset Cash Adjustment;
provided, however, that the Buyout Amount shall not be less than 50% of the
- --------  -------                                                          
Merger Agreement Consideration.

          (ii) If prior to the date of Termination of this Agreement, PHC has
completed an initial public offering of PHC Common Stock, the Service Provider
may pay such portion of the Buyout Amount through paying cash in the amount of
$4.00 per share of PHC Prime Common or PHC Common Stock not paid to PHC.


     C.  GENERAL. For purposes of this Exhibit 8.4(a), "fair market value" of
PHC Prime Common Stock or PHC Common Stock: (i) if determined prior to any
initial public offering of PHC Common Stock, shall be determined by PHC's Board
of Directors in good faith based on the most recently completed sale of PHC
Prime Common Stock (or PHC Common Stock, as applicable) by PHC, and (ii) if
determined after any initial public offering of PHC Common Stock, shall be the
average closing sale price of PHC Common Stock for the ten trading days prior to
the closing of the repurchase.

     For purposes of this Exhibit 8.4(a), all share amounts and assumed values
per share shall be adjusted as necessary to reflect any stock splits, dividends,
reverse splits or other recapitalizations to the PHC Prime Common Stock or PHC
Common Stock (as applicable) after the date hereof.

              extensions) and are true, correct and complete in all material
              respects.  Except as disclosed in SCHEDULE 4.24,  (i) the

              has ever been made by any governmental authority in a
              jurisdiction where the Practice Group does not file Tax Returns

              jurisdiction.

          (d) All Taxes of the Practice Group which have become due (without
              regard to any extension of the time for payment and whether or not

              Capital Amount. For this purpose, the portion of any Tax imposed
              on a periodic basis that is attributable to a taxable period
              beginning before and ending after the Closing Date shall be
              determined by apportioning the Tax for the entire period based
              upon the number of days in the period, except that any such Tax
              measured by income or receipts shall be apportioned based upon
              actual results of operations through the end of the Closing Date.

              process, pending or, to Physician's or Practice Group's knowledge,
              threatened (verbally or in writing). No waiver or extension of any
              statute of limitations relating to the assessment or collection of
              any Tax of the Practice Group is in effect. There are no
              outstanding requests for rulings with any taxing authority
              relating to Taxes of the Practice Group.

asserted against, relating to, imposed upon, or incurred by PHC by reason of,
resulting from, based upon, or arising out of:

          (a) The inaccuracy, untruth, or incompleteness of any representation
              or warranty of Practice Group and/or Physician contained in or
              made pursuant to this Agreement;

          (b) The failure of Practice Group and/or any physician to comply with

made by PHC or PHC-SUB in this Agreement or any Schedules delivered by any of
them pursuant hereto or any right of indemnification of Physician under Section
                                                                        -------

          (b) The failure of PHC or PHC-SUB to comply with any of the covenants
              made by PHC in this Agreement.

     10.3 Definition of Losses.  For the purposes of this ARTICLE X, "Losses"
          --------------------                            ---------          
shall mean any and all demands, claims, actions or causes of action,
assessments, losses, damages, liabilities, costs, and expenses, including,
without limitation, interest, penalties, and reasonable attorneys' and other
professional fees, and expenses incurred in the investigation, preparation,
defense, and settlement of any claim, loss, damage, or liability as to which a
party is entitled to indemnification hereunder.

     10.4 Notice and Opportunity to Defend.
          -------------------------------- 

          (a) The party indemnified hereunder (the "Indemnified Party") shall
              notify in writing the indemnifying party (the "Indemnifying
              Party") within thirty (30) days after a claim is presented to the
              Indemnified Party, and the Indemnifying Party shall defend such
              claim at its expense. If the Indemnifying Party does not defend or
              settle such claim, the Indemnified Party may do so without the
              Indemnifying Party's participation, in which case the Indemnifying
              Party shall pay the reasonable expenses of such defense, and the
              Indemnified Party may settle or compromise such claim without the
              Indemnifying Party's consent. If the Indemnified Party fails to
              notify the Indemnifying Party, and if the Indemnifying Party is
              thereby materially prejudiced by such failure of notice in its
              defense of the claim, the

<PAGE>
 
              Indemnifying Party's obligation of indemnity hereunder shall be
              extinguished with respect to such claim to the extent that the
              Indemnifying Party has been prejudiced by the failure to give such
              notice.

          (b) Anything herein to the contrary notwithstanding, no party shall
              make any claim against any other party pursuant to this ARTICLE X
                                                                      ---------
              unless the dollar amount of all Losses suffered or incurred by the
              party seeking such indemnity hereunder shall exceed, in the
              aggregate, the amount of Twenty-Five Thousand and No/100 Dollars
              ($25,000.00), but, if such amount is exceeded, the Indemnifying
              Party shall be required to pay the full amount of such aggregate
              Losses (up to nine million dollars ($9,000,000) (the "Cap Amount")
              and without deduction for such Twenty-Five Thousand and No/100
              Dollars ($25,000.00) threshold amount) for which indemnification
              rights and obligations are provided under this ARTICLE X.
                                                             --------- 

              The foregoing notwithstanding, the Cap Amount shall not apply to
              Losses suffered or incurred in connection with (i) medical
              malpractice or professional liability claims in excess of the
              insured limits provided for in the professional liability
              insurance policies maintained for the benefit of the Practice
              Group and professional employees and/or Physician of the

               arbitrator's final decision. Other than petitioning a court to
               enter a judgment based upon the arbitrator's final decision, the
               parties, their representatives, other participants and the

this Agreement and all agreements and documents contemplated hereby by Acquiror

provided, however, that Closing is subject to approval by the Acquiror's Board
of Directors.  This Agreement constitutes, and all agreements and documents
contemplated hereby (when executed and delivered pursuant hereto for value
received) will constitute, the valid and legally binding obligations of Acquiror
and Merger Sub, enforceable in accordance with their terms, except as the same

the parties cannot agree upon a mediator.  The parties shall bear their own
costs associated with the mediation and shall share equally the costs of the
mediator.  If the parties do not resolve the dispute within sixty (60) days from
the commencement of the mediation and do not mutually agree to extend the sixty
(60) day period, either party may elect to submit the dispute to binding
arbitration.  The parties, their representatives, other participants and the
mediator shall hold the existence, content and result of the mediation in

              ---------------                                                
the dispute to binding arbitration, the dispute shall be submitted to a sole
arbitrator, whose decision shall be final and binding on the parties.  The
parties shall select the arbitrator by mutual agreement or, if the parties fail
to agree upon an arbitrator within thirty (30) days from the date of the
election to arbitrate, the arbitrator shall be selected by the American
Arbitration Association.  The Commercial Arbitration Rules of the American
Arbitration Association shall govern the arbitration, including the selection of
the arbitrator if the parties cannot agree upon the arbitrator.  The parties
shall bear their own costs associated with the arbitration and shall share
equally the costs of the arbitrator.   In the event that either party fails to
comply with the terms of the arbitrator's final decision within twelve (12)
months of said decision, either party may petition a court of competent
jurisdiction to enter a judgment  based upon the arbitrator's final decision.
Other than petitioning a court to enter a judgment based upon the arbitrator's
final decision, the parties, their representatives, other participants and the
arbitrator shall hold the existence, content and result of the arbitration in
confidence.  The arbitration shall be held in Atlanta, Georgia.

(the "Purchase Price") will be equal to the face amount of the Accounts
Receivable recorded each month in a final billable form, less (i) any non-
allowed contractual adjustments imposed by Third Party Payor Programs, and (ii)
any reserve for uncollectible Accounts Receivable. The Purchase Price will be
estimated each month to take into account contractual adjustments and
uncollectible Accounts Receivable based on the most recently completed six (6)
month historical experience of the Practice or the predecessor of the Practice,

intent of the parties that the Purchase Price reflect the actual net realizable
value of the Accounts Receivable.

Receivable, MidSouth shall remit the amount of the underpayment to the Practice
on the next date on which MidSouth purchases Accounts Receivable from the
Practice. In the event the Yearly Adjustments to the Purchase Price indicate
that MidSouth has overpaid for Purchased Accounts Receivable, the Practice shall
remit to MidSouth the amount of such overage on the next date on which MidSouth
purchases Accounts Receivable from the Practice. MidSouth shall pay the Practice
for all Purchased Accounts Receivable by check, wire transfer or intrabank
transfer to the Practice Account. The purchase of Accounts Receivable shall be
evidenced by the Practice sending MidSouth (i) a copy of each invoice with
respect to each third-party payor on the Purchased Accounts Receivable; and (ii)
any other information or documentation (including all required Uniform
Commercial Code ("UCC") releases or financing statements) MidSouth may
reasonably need to identify the Purchased Accounts Receivable and obtain payment
from the Account Debtors; provided that the failure to send any documentation
shall not affect the obligation of the Practice to sell the Purchased Accounts
Receivable or MidSouth to purchase the Purchased Accounts Receivable. As
consideration for the acquisition of the Purchased Accounts Receivable by
MidSouth pursuant to this Section 6.2, MidSouth promises to pay and shall be
obligated to pay the Purchase Price for the Purchased Accounts Receivable at the
time and in the manner provided above. To the extent permissible by Applicable
Law, the Practice will be deemed to have sold to MidSouth all of the Practice's
right, title and interest in the Purchased Accounts Receivable and in any
proceeds thereof, and MidSouth will be the sole and absolute owner thereof and
will own all of the Practice's rights and remedies

reason; (i) all Accounts Receivable purchased by MidSouth shall remain the

                                       21
<PAGE>
 
to each Account Debtor on the related Non-Governmental Receivable regarding
making payments to the Lockbox Account. Any action shall be considered a breach
of this Agreement for which MidSouth shall be entitled to all remedies under
Applicable Law and in equity, including obtaining an injunction.

     (iii) The Practice will cooperate with MidSouth and its agents in the
identification of sums deposited into the Non-Governmental Lockbox Account,
which cooperation shall continue until all Purchased Accounts Receivable sold
hereunder have been collected.

     (iv) The Practice agrees to pay, on demand, a finance charge equal to the
Finance Charge Rate, on any Non-Governmental Receivable received by the Practice
that is not deposited in the Non-Governmental Lockbox Account within two (2)
business days after receipt by the Practice.

     (c) PROCEDURES WITHOUT LOCKBOX. It is MidSouth's intention to utilize the
         --------------------------                                         
Governmental Lockbox Account and Non-Governmental Lockbox Account procedure as
provided in Section 6.2.6(a) and (b) unless circumstances change which would
make the Governmental Lockbox Account and Non-Governmental Lockbox Account
procedures inappropriate. The procedures under this subsection (c) for the
collection of Accounts Receivable without a lockbox will not be instituted
without approval of the Management Team. The Practice and MidSouth shall
instruct the Collecting Bank to transfer automatically all amounts constituting
good funds in the account or accounts of the Practice established for the
collection of Governmental Receivables and Non-Governmental Receivables to the
bank account established with the Lender pursuant to a standing order in a form
acceptable to MidSouth's legal counsel (the "Bank Account"). In the event
MidSouth exercises this option, the Practice shall instruct each Account Debtor
with respect to the Purchased Accounts Receivable to remit all payments directly
to the Collecting Bank account or accounts pursuant to a Notification Letter. In
addition, the Practice shall attach written instructions to each invoice
representing the Purchased Account Receivable generated subsequent to the date
of this Agreement instructing such third-party payor or Account Debtor that
payment under the invoice is to be paid to the Collecting Bank account or
accounts. The Practice shall not, so long as any Purchased Accounts Receivable
remain outstanding, change or cancel such standing order at any time, or,
without the prior written consent of MidSouth, change the instructions to each
Account Debtor on each Governmental Receivable and Non-Governmental Receivable
to make its payments to such account. Any such action shall be considered a
breach of this Agreement for which MidSouth shall be entitled to all remedies
under Applicable Law and in equity, including obtaining an injunction.

     (d) MISDIRECTED PAYMENTS. (i) If after the date of this Agreement, an
         --------------------                                           
Account Debtor shall make a payment on the Purchased Accounts Receivable to a
location other than is provided in the Notification Letter or the Practice
otherwise receives payments on Purchased Accounts Receivable under the terms of
this Agreement ("Misdirected Payments"), the Practice (at its own cost and
expense) shall promptly take all necessary steps to effect collection of the
Misdirected Payment from any other party claiming an interest therein or having
possession thereof and (A) hold the Misdirected Payment in trust for MidSouth,
(B) segregate the Misdirected Payment, (C) use its

                                       22
<PAGE>
 
best efforts not to commingle the Misdirected Payment with the Practice's own
funds or other assets, and (D) deliver the Misdirected Payment no later than two
(2) business days from the day of receipt to the Collecting Bank account or
accounts, as applicable.

     (ii) The Practice agrees to pay, on demand, the Finance Charge Rate on any
Misdirected Payment received by the Practice that is not deposited in the
appropriate account within two (2) business days after receipt by the Practice.

     (e) All Purchased Accounts Receivable of the Practice pursuant to this
Section 6.2 hereof will, as the Purchased Accounts Receivable are purchased, be
treated as Practice Revenues for accounting and financial purposes.

     SECTION 6.3. EARLY TERMINATION OF PHYSICIAN MEMBERS. The Physician Members
                  --------------------------------------                     
hereby acknowledge that the terms and conditions of this Agreement are based
upon numerous factors, including the Physician Members continuing to practice
medicine in the future. In connection therewith, each Physician Shareholder
agrees as follows:

     (a) RETIREMENT. If at any time during the Term hereof, a Physician
         ----------                                                    
Shareholder desires to retire, or assume full-time teaching responsibilities,
the Physician Shareholder shall notify MidSouth in writing at least twelve (12)
months prior to the date of such retirement or start of teaching position;
provided, however, that if such retiring physician elects to, and has located a
replacement physician suitable to the Practice, MidSouth shall waive the
remaining months of said twelve (12) month notice period, and such retirement
shall be effective upon the earlier of twelve (12) months from the date of
notice or commencement of the replacement physician's employment. Upon such
retirement or start of the teaching position, the Physician Shareholder shall
have no further obligations under this Agreement; provided, however, the
restrictive covenants provided for under Article Section 7 shall remain in full
force and effect. In fulfilling any such full-time teaching responsibilities,
the Physician Shareholder will be permitted to attend patients in a manner
normal and customary for such faculty position; provided, however, such services
must be incident to the academic/teaching aspects of the institution, and not
incident to the regular examination of patients for a fee whether billed in the
name of the institution or the name of the attending physician. It is not the
intent of the parties to permit a retired physician to conduct a medical
practice through an academic institution.

     (b) PHYSICIAN SHAREHOLDER CHANGE IN PRACTICE/GROUP AFFILIATION. In the
         ----------------------------------------------------------        
event that a Physician Shareholder leaves the employment of or terminates his or
her affiliation with the Practice, the terminating Physician Shareholder may
join or establish another group/practice which has or will enter into a service
agreement with MidSouth, subject to any other existing agreements between
Physician Shareholder and Practice. Upon entering into such new service
agreement with MidSouth, the terminating Physician Shareholder shall, except as
limited by separate employment agreements between the Practice and the Physician
Members, be released from any obligation under this Agreement. In the event the
(i) Practice consents to MidSouth entering into a new service agreement; (ii)
service agreement will not adversely affect the operations and earnings of
MidSouth; and (iii) new group/practice can satisfy the representations and
warranties set forth in Article 12

                                       23
<PAGE>
 
hereof, then MidSouth will not unreasonably withhold or refrain from entering
into a new service agreement with the terminating Physician Shareholder's new
group/practice. Except as set forth herein, in the event the Physician
Shareholder affiliates with a new group/practice that is not a party to a
service agreement with MidSouth, then MidSouth, will terminate this Agreement
solely with respect to the terminating Physician Shareholder; provided, however,
that the provisions of Article 7 hereof shall apply. In the event that MidSouth
does not enter into a new service agreement, then MidSouth shall terminate this
Agreement with respect to the Physician Shareholder, and the terminating
Physician Shareholder shall be obligated as set forth in Article 7 hereof

     (c) DEATH OR DISABILITY. In the event that a Physician Shareholder dies or
         -------------------                                                 
becomes disabled, then the Physician Shareholder shall have no continuing
obligations under this Agreement; provided, however, in the event of disability,
the restrictive covenants described in Article 7 hereof shall remain in full
force and effect.

               ARTICLE 7. RESTRICTIVE COVENANTS AND ENFORCEMENT.
                          ------------------------------------- 

     MidSouth and the Practice recognize that the benefits each is to receive
under this Agreement shall be realized only if the Practice operates an active
medical practice to which the physicians associated with the Practice devote
their full time and attention to the extent of their arrangement with the
Practice. Accordingly, MidSouth and the Practice desire to set forth the
following reasonable restrictions and agreements regarding competition by the
physicians during the term of this Agreement and after the termination of this
Agreement.

     SECTION 7.1. EXCLUSIVE ARRANGEMENT. During the term of this Agreement,
                  ---------------------                                   
MidSouth shall be the Practice's and the Physician Members' sole provider of the
management services described in this Agreement and neither the Practice, the
Physician Members nor any of the Practice's or the Physician Members' employees
shall provide similar management services. During the term of this Agreement,
the Practice and the Physician Members agree that neither the Practice nor
Physician Members will enter into any similar agreement with any physician
practice management company or entity.

     SECTION 7.2. RESTRICTIVE COVENANTS BY THE PRACTICE. The Practice agrees
                  -------------------------------------                     
that, during the term hereof, neither the Practice or its Physician Employees
will engage, directly or indirectly, as a principal owner, shareholder (other
than a holder of fewer than 5% of the outstanding shares of a publicly-traded
company), partner, joint venturer, employee, agent, equity owner, or in any
other capacity whatsoever, in any corporation, partnership, joint venture, or
other business association or entity that operates ambulatory surgery or
diagnostic centers, imaging centers, physical therapy centers, or rehabilitation
centers, or provides management services of the nature provided by MidSouth
pursuant to this Agreement in the Restricted Area. Provided that this Agreement
may allow any Physician Employee to own any ownership interest in the above
facilities which was acquired prior to the execution this Agreement. If this
Agreement is terminated by MidSouth for breach by the Practice, pursuant to 10.4
hereof, neither the Practice nor its current or future Physician Employees shall
establish, operate, or provide physician services at any medical office, clinic,

                                       24
<PAGE>
 
ambulatory surgery or diagnostic centers, imaging centers, physical therapy
centers, rehabilitation centers or other health care facility providing services
substantially similar to those provided by the Practice within the Restricted
Area for a period of twenty-four (24) months ("Restricted Period") after the
termination of the Agreement.

     SECTION 7.3. RESTRICTIVE COVENANTS BY CURRENT PHYSICIAN EMPLOYEES.
                  ---------------------------------------------------- 
Contemporaneous with the execution of this Agreement, the Practice shall obtain
formal agreements from its current Physician Employees, pursuant to which each
agrees during the term of their respective employment and for the Restricted
Period after any termination of employment with the Practice, they will not (i)
establish, operate or engage, directly or indirectly, as a principal owner,
shareholder (other than a holder of fewer than 5% of the outstanding shares of a
publicly-traded company), partner, joint venturer, employee, agent, equity
owner, or in any other capacity whatsoever, in any corporation, partnership,
joint venture, or other business association or entity that operates ambulatory
surgery or diagnostic centers, imaging centers, physical therapy, or
rehabilitation centers providing services similar to those provided by the
Practice within the Restricted Area; or (ii) solicit, induce or attempt to
induce any Practice patient, employee, consultant or other persons associated or
affiliated with MidSouth or any Affiliate of MidSouth to leave the care of a
Physician Employee, to leave the employment of, or to discontinue their
association with the Practice, MidSouth or such affiliate of the Practice or
MidSouth within the Restricted Area. Provided that the employment agreements may
exclude from the restrictive covenant the employment of Physician Employees in
facilities that have historically been deemed emergency room facilities once the
Physician Employee's employment has been terminated if the Physician Employee
has no private practice. The employment agreements shall provide that MidSouth
is an intended third-party beneficiary to such agreements and that such third-
party beneficiary rights may be assigned to any Lender. The Practice agrees to
enforce the restrictive covenants. The cost and expense of such enforcement
shall be a Practice Expense, and all damages and other amounts recovered thereby
shall be considered Practice Revenue. In the event that after a request by
MidSouth, the Practice does not pursue any remedy that may be available to it by
reason of a breach or Default of a restrictive covenant, such event shall not be
a Default or breach of this Agreement and upon the request of MidSouth, the
Practice shall assign to MidSouth such causes of action and/or other rights it
has related to such breach or Default and shall cooperate with and provide
reasonable assistance to MidSouth with respect thereto; in which case, all costs
and expenses incurred in connection therewith shall be MidSouth Expenses, and
MidSouth shall be entitled to all damages and other amounts recovered thereby.
If the Practice and/or any Physician Employee violate the covenants set forth in
this Section 7.3, then the duration of the restrictions contained in this
Section 7.3 shall be extended an additional month against the violator for each
month during which such violation occurred but was not discovered by MidSouth,
beginning upon the date that MidSouth learns of the violation and so notifies
the Practice and/or the Physician Employee in writing.

     SECTION 7.4. RESTRICTIVE COVENANTS BY FUTURE PHYSICIAN EMPLOYEES. The
                  ---------------------------------------------------   
Practice shall obtain and enforce formal agreements from each of its future
Physician Employees hired or contracted, pursuant to which each agrees to be
bound by an agreement containing the terms and conditions as contained in
Section 7.3 hereof.

                                       25
<PAGE>
 
     SECTION 7.5. PHYSICIAN EMPLOYEE LIQUIDATED DAMAGES. The restrictive
                  -------------------------------------                 
covenants described above may provide that the Physician Employees (current or
future) may be released from their Restrictive Covenants by paying liquidated
damages in an amount as follows:

     (a) if the Practice were the breaching party or the party desiring to be
released from the covenant, the Practice shall be liable to MidSouth for an
amount equal to the reasonably estimated fee payable to MidSouth hereunder for
one hundred twenty (120) months following the termination; and

     (b) if a Physician Employee was the breaching party or the party desiring
to be released from the covenant, then S200,000.00 per breaching party or party
desiring to be released from the covenant must be paid to MidSouth in order to
obtain Physician Employee's release from Article 7 of this Agreement.

     SECTION 7.6. RIGHTS OF MIDSOUTH. During the term of this Agreement and
                  ------------------                                     
thereafter, MidSouth shall at all times of this Agreement have the right to
enter into additional service agreements with other physicians and practices,
regardless of where such physicians and/or practices are located, providing for
management services and facilities to such physicians and/or practices.

     SECTION 7.7. EXCLUDED ACTIVITIES. Physician Employees shall be allowed to
                  -------------------                                       
participate in Excluded Activities and retain Excluded Revenues, at any time so
long as the Excluded Activities do not materially interfere with any rights,
responsibilities or obligations as contained in this Agreement or any employment
agreement by and between the Practice and the Physician Employee.

     SECTION 7.8. ENFORCEMENT. MidSouth, the Practice and the Physician Members
                  -----------                                                  
acknowledge and agree that since a remedy under Applicable Law for any breach or
attempted breach of the provisions of this Article 7 shall be inadequate,
MidSouth shall be entitled to specific performance and injunctive or other
equitable relief in the event of any breach or attempted breach, in addition to
whatever other remedies may exist under Applicable Law or in equity. If any
provision of Article 7 relating to any applicable Restrictive Period, scope of
activity restricted or the Restricted Area described therein shall be declared
by a court of competent jurisdiction to exceed the maximum time period, scope of
activity restricted or geographical area the court deems reasonable and
enforceable under Applicable Law, the time period, scope of activity restricted
and/or area of restriction held reasonable and enforceable by the court shall
thereafter be the Restrictive Period, scope of activity restricted and/or the
Restricted Area applicable to the restrictive covenant provisions in this
Article 7. The invalidity or non-enforceability of this Article 7 in any respect
shall not affect the validity or enforceability of the remainder of this Article
7 or of any other provisions of this Agreement.

Commissioner of the State. If the Practice's existing professional liability
insurance program is canceled and replaced by a professional liability insurance

indirectly, by or as a result of the performance of medical services or the
performance of any intentional acts, negligent acts or omissions by the Practice
and/or its members, agents, employees and/or subcontractors (other than MidSouth
or any other party engaged by MidSouth) during the

directly or indirectly, by or as a result of the performance of any intentional
acts, negligent acts or omissions by MidSouth and/or its members, agents,
employees and/or subcontractors (other than the Practice) during the term of
this Agreement or as a result of a breach of the representations and warranties
contained in Article 13 of this Agreement. In addition, MidSouth shall

a claim for indemnification under either the Merger Agreement or this Agreement
(the "Indemnified Party"), then the party who must provide indemnity (the
"Indemnifying Party"), shall have the right, to the extent it owes
indemnifications, to pay amounts owed to the Indemnified Party under the Merger
Agreement or this Agreement into an escrow account (established pursuant to an
escrow agreement to be agreed upon by the parties) to be held by the escrow
agent in an interest bearing account until a determination by either (i) the
parties, (ii) a court of proper jurisdiction or (iii) an agreed upon panel of
arbitrators, has been made regarding the Indemnified Party's right to
indemnification. In the event that the Indemnified Party is entitled to
indemnification, then such escrowed funds shall be paid to the Indemnified Party
in partial or complete satisfaction of such indemnification obligation. Any
excess funds remaining in the escrow account after the payment of the
indemnification obligation or any funds held in escrow account if it is
determined that no indemnification obligation is owed shall be paid to the
Indemnifying Party.

their mutual objectives is the development of Proprietary Information to be used
in connection with MidSouth's operations or which MidSouth intends to use or
license in its relationship with third parties, including other

the Practice acknowledges that as of the Closing Date, by virtue of execution

Information, as well as existing Proprietary Information, excluding patient
medical records, regardless of whether the new Proprietary Information is
developed by one or more physicians in the Practice or Affiliates. The Practice
agrees to execute and deliver such documentation as may be requested by MidSouth
from time to time to evidence such ownership. During the term of this Agreement,
MidSouth shall license and provide access to all existing Proprietary
Information to the Practice.

provision of its services under this Agreement shall remain the property of
MidSouth and may be removed by MidSouth upon any termination of this Agreement;
provided, however, that the Practice shall be entitled, upon reasonable written
request, to access such records and make copies or extracts thereof to the
extent necessary to prosecute or defend against any tax or other liabilities
imposed on the Practice by any Governmental Authority or other party.

provided in this Agreement, the parties shall safeguard all records maintained
by them pursuant to this Agreement for a period of time specified by the
Management Team from the date of the last activity recorded in such records. In
particular, the parties agree, to the extent necessary to permit receipt of
reimbursement for services by the Practice, to make available to the Secretary
of the United States Department of Health and Human Services, the Comptroller
General at the General Accounting Office, or their authorized representatives,
any books, documents and records in their possession relating to the nature and
extent of the costs of services hereunder for a period of four (4) years after
the provision of such services. Each party further agrees that, if it contracts
with any third party to provide services that are valued in excess of $10,000,
it shall require the contracting party to comply with the requirements of the
previous sentence. During the term of this Agreement, and thereafter, the
Practice or its designee shall have reasonable access during normal business
hours to the Practice's and MidSouth's financial and accounting, including, but
not limited to, records of collections, expenses and disbursements as kept by
MidSouth in performing MidSouth's obligations under this Agreement, and the
Practice may copy any or all records at its expense. Nothing in this Section
11.3 constitutes the waiver of any attorney-client privilege, and neither party
shall be required hereunder to give the other party document if, as a result, an
existing attorney-client privilege would be waived.

     SECTION 11.4. PATIENT RECORDS. Upon termination of this Agreement, the
                   ---------------                                         
Practice shall retain all patient medical records maintained by the Practice or
MidSouth in the name of the Practice.

     SECTION 11.5. ACCESS TO RECORDS. During the term of this Agreement, and
                   -----------------                                      
thereafter, the Practice or its designee shall have reasonable access during
normal business hours to the Practice's and MidSouth's financial records,
including, but not limited to, records of collections, expenses and

                          ARTICLE 15. MISCELLANEOUS.
                                      -------------

     SECTION 15.1. ASSIGNMENT. MidSouth shall have the right to assign without
                   ----------                                                 
the consent of the Practice all of its rights hereunder to any person, firm or
corporation (i) under common control with MidSouth, (ii) to any lending
institution, for security purposes or as collateral, from which MidSouth obtains
financing, or (iii) that is an affiliate of MidSouth, including, but not limited
to, a parent, subsidiary, or brother-sister corporation, and MidSouth shall have
the right to assign with the consent of the Practice (which shall not be
unreasonably withheld) all rights hereunder to any firm, person or corporation
that merges, reorganizes, or otherwise consolidates with MidSouth and further
agrees that upon receipt of notice from such assignee, the Practice shall pay to
the assignee or cause to be paid to the assignee all amounts due and payable to
MidSouth pursuant to this Agreement. Without limiting the foregoing, the
Practice acknowledges that, as collateral for certain obligations, MidSouth has
assigned all of its rights hereunder to a Lender as Agent (the "Agent") for
itself and other banks and institutional lenders from time to time (collectively
the "Banks") and has granted the Agent for the benefit of the Banks a lien and
security interest upon all real and personal property

                                       42
<PAGE>
 
owned by MidSouth ("Pledged Assets"). As an inducement for the Banks to extend
or continue the extension of credit to MidSouth, the Practice (i) acknowledges
that the collateral assignment to the Agent covers all rights of MidSouth
hereunder, including, but not limited to, rights arising from warranties and
representations made by the Practice, rights to enforce covenants made by the
Practice, and rights to receive all payments due MidSouth; (ii) agrees to regard
the Agent as the owner of any and all of the assigned rights upon written notice
to the Practice of this election from the Agent; (iii) agrees that neither the
Agent nor any of the Banks has obligation for the performance of the duties of
MidSouth hereunder, and shall not assume any such duty by the exercise of rights
as a secured lender; (iv) agrees to give the Agent written notice of any
Material Default hereunder on MidSouth's part at the address provided in writing
to Practice by the Agent and to allow cure periods as provided in Section 10.3
thereafter for the cure of Default before the Practice terminates this
Agreement; (v) agrees that the rights of the Practice under this Agreement,
including, but not limited to, the right to the use of the Pledged Assets, are
and shall be junior to any security interest that the Agent and the Banks, their
successors or assigns may have in the Pledged Assets at any time; (vi) agrees
that the benefits of the above undertakings in favor of the Agent and Banks
shall further extend to all successors and assigns of the Agent and Banks,
provided that any notices given by the Practice under this Section 15.1 shall be
given to the Agent at the foregoing address unless the Practice has received
written notice of a change thereof; and (vii) agrees that this Section 15.1 may
not be modified, and no provision of this Section 15.1 may be waived, absent the
written approval of the Agent and Banks. Further, if a majority of the
shareholders of MidSouth entitled to vote on a sale of all of the assets or
substantially all of the assets or common stock of MidSouth authorize the sale
or transfer of all or substantially all of the assets or common stock of
MidSouth to a third party (the "Acquiring Party"), this Agreement shall be
deemed automatically assigned and transferred to the Acquiring Party without the
necessity of obtaining the consent of the Practice. Except as set forth above,
neither MidSouth nor the Practice shall have the right to assign their
respective rights and obligations hereunder without the written consent of the
other party.

     SECTION 15.2. THIS AGREEMENT. This Agreement sets forth the entire
                   ----------------

supersedes and discharges all prior agreements (written or oral) and
negotiations and all contemporaneous oral agreements concerning the subject
matter. There are no oral conditions precedent to the effectiveness of this
Agreement.

     SECTION 15.3. NO PRACTICE OF MEDICINE. The parties acknowledge that
                   -----------------------
MidSouth is not authorized or qualified to engage in any activity which may be
construed or deemed to constitute the practice of medicine. To the extent any
act or service required of MidSouth in this Agreement should be construed or
deemed by any Governmental Authority or court to constitute the practice of
medicine, the performance of said act or service by MidSouth shall be deemed
waived and unenforceable to the minimum extent required to comply with
Applicable Law.

     SECTION 15.4. NON-WAIVER. Neither the failure of nor any delay by any party
                   ----------
to this Agreement to enforce any right hereunder or to demand compliance with
its terms is a waiver of any right hereunder. No action or inaction taken
pursuant to this Agreement on one or more occasions is a waiver of any right
hereunder or constitutes a course of dealing that modifies this Agreement.

the party to be charged. No waiver of any right or remedy under any term of this
Agreement shall in any event be deemed to apply to any subsequent Default under
the same of any other term contained herein.

the invalidity of all or any part of any term of this Agreement shall not render
invalid the remainder of this Agreement or the remainder of the term. If any
term of this Agreement is so broad as to be unenforceable, the term shall be
interpreted to be only so broad as is enforceable.

     SECTION 15.8. SUCCESSORS. The terms of this Agreement shall be binding upon
                   ----------                                                
and inure to the benefit of the parties, their respective successors, assigns,
heirs and beneficiaries.

     (b)(l) Billing and Collecting. MidSouth shall, on behalf of the Practice,
            ----------------------                                            
bill patients and Third Party Payor Programs and collect the fees for medical
services rendered by the Practice regardless of when or where such services are
rendered. All billings for Technical Employees' and Physician Employees'
services shall be made in the name of and under the provider number of the
Practice. The Practice hereby appoints MidSouth for the term hereof to be its
true and lawful attorney-in-fact, for the following purposes: (i) to bill
patients in the Practice's name and on its behalf; (ii) to collect Accounts
Receivable resulting from billing in the Practice's name and on its behalf;
(iii) to receive payments and prepayments from Third Party Payor Programs; (iv)
to take possession of and endorse in the name of the Practice (and/or in the
name of an individual physician, the payment intended for purpose of payment of
a bill) any notes, checks, money orders, insurance payments and other
instruments received in payment of Accounts Receivable; and (v) at the direction
of the Management Team to initiate the institution of legal proceedings in the
name of the Practice to collect any Accounts Receivable and monies owed to the
Practice, to enforce the rights of the Practice as creditors under any Contract
or in connection with the rendering of any service, and to contest adjustments
and denials by governmental agencies (or its fiscal intermediaries) as third
party payors. All adjustments made for uncollectible accounts, professional
courtesies and other activities that do not generate a collectible fee shall be
performed in a reasonable and consistent manner approved by the Management Team.

     (b)(2) Bank Accounts. All cash, checks and credit card purchases paid at
            -------------
the time of the delivery of medical services by the Practice shall be remitted

the Purchased Accounts Receivable shall be deposited into the respective
Governmental Lockbox Account or Non-Governmental Lockbox Account. Proceeds
collected in the Governmental Lockbox Account and the Non-Governmental Lockbox
Account shall be automatically swept daily into the Disbursement Account.
MidSouth will transfer monies from the Disbursement Account to the Practice
Account for the payment of the Purchase Price. On the Settlement Date pursuant
to Article VI hereof, Practice shall transfer monies from the Practice Account
to the Disbursement Account to pay the Service Fee due to MidSouth for all cash,
checks, and credit card purchases and other payments received (i.e., prepay
capitation fees) prior to the time of delivery of medical services. The Practice
shall establish and maintain a separate account for the Practice, which is the
Practice Account. The Practice Account shall be controlled solely by the
Practice. The parties acknowledge and agree that in the event that the mix
between Accounts Receivable and non-Accounts Receivable receipts is altered to
the point where proceeds from Accounts Receivable are not sufficient to pay for
the Service Fee, the parties will establish mutually agreeable terms to allow
MidSouth access to the Practice Account to pay the Service Fee. The Practice
shall use the monies in the Practice Account to pay all the Excluded Expenses.
MidSouth will transfer monies to the Practice Account to remit, on a monthly
basis, the Purchase Price for the Purchased Accounts Receivables. The
calculation of the Purchase Price will be made so that the Practice will receive
an amount equal to the face amount of the Accounts Receivable recorded each
month, less any non-allowed contractual and instruments and net of any reserve

     SECTION 6.2. PURCHASE OF ACCOUNTS RECEIVABLE.
                  -------------------------------

     Section 6.2.l. On the date hereof, MidSouth has purchased the Accounts
Receivable set forth on Schedule 6.2.1 attached hereto (the "Initial Purchased
Accounts Receivable"). The Initial Purchased Accounts Receivable shall be billed
and collected in accordance with the provisions of the Agreement. During the
Term of this Agreement, the Practice hereby agrees to sell and assign to
MidSouth and MidSouth agrees to purchase, all of the Practice's Accounts
Receivable generated each month ("Purchased Accounts Receivable"). Purchased
Accounts Receivable shall not include, and MidSouth shall not purchase, any
cash, checks or credit card receivables.

     Section 6.2.2. The purchase price for the Purchased Accounts Receivable
(the "Purchase Price") will be equal to the face amount of the Accounts
Receivable recorded each month in a final billable form, less (i) any non-
allowed contractual adjustments imposed by Third Party Payors 

                                       19
<PAGE>
 
Program, and (ii) any reserve for uncollectible Accounts Receivable. The
Purchase Price will be estimated each month to take into account contractual
adjustments and uncollectible Accounts Receivable based on the most recently
completed six (6) month historical experience of the Practice or the predecessor
of the Practice, calculated on a rolling basis, as determined by MidSouth. It is
the intent of the parties that the Purchase Price reflect the actual net
realizable value of the Accounts Receivable.

     Section 6.2.3. The Practice will sell all Accounts Receivable to MidSouth
and each purchase will be deemed to be made on the day after which the Accounts
Receivable are created. MidSouth shall pay the estimated Purchase Price for the
Purchased Accounts Receivable no later than the tenth (lOth) day of each month
following the month in which the Purchased Accounts Receivable are created (the
"Settlement Date"). MidSouth and the Practice will determine the actual Purchase
Price based on the actual amount realized from the Purchased Accounts Receivable
on an annual basis as set forth in Section 6.1(b). MidSouth shall pay the
Practice for all Purchased Accounts Receivable by check, wire transfer or
intrabank transfer to the Practice Account. The purchase of Accounts Receivable
shall be evidenced by the Practice sending MidSouth (i) a copy of each invoice
with respect to each third-party payor on the Purchased Accounts Receivable; and
(ii) any other information or documentation (including all required Uniform
Commercial Code ("UCC") releases or financing statements) MidSouth may
reasonably need to identify the Purchased Accounts Receivable and obtain payment
from the Account Debtors; provided that the failure to send any documentation
shall not affect the obligation of the Practice to sell the Purchased Accounts
Receivable or MidSouth to purchase the Purchased Accounts Receivable. As
consideration for the acquisition of the Purchased Accounts Receivable by
MidSouth pursuant to this Section 6.2. MidSouth promises to pay and shall be
obligated to pay the Purchase Price for the Purchased Accounts Receivable at the
time and in the manner provided above. To the extent permissible by Applicable
Law, the Practice will be deemed to have sold to MidSouth all of the Practice's
right, title and interest in the Purchased Accounts Receivable and in any
proceeds thereof, and MidSouth will be the sole and absolute owner thereof and
will own all of the Practice's rights and remedies represented by the Purchased
Accounts Receivable (including, without limitation, rights to payment from the
respective Account Debtors on the Purchased Accounts Receivable), and MidSouth
will have obtained all of the Practice's rights under all guarantees,
assignments and securities with respect to all of the Purchased Accounts
Receivable.

     Section 6.2.4. MidSouth hereby grants the Practice a subordinated security
interest in the amount necessary to fund MidSouth's obligation to pay the
Purchase Price for the Purchased Accounts Receivable which will be transferred
on a daily basis pursuant to Section 6.2.3. until the Purchase Price is paid.
Practice's security interest shall only be subordinate to the Lender's security
interest in the Purchased Accounts Receivable. MidSouth shall execute any and
all documentation necessary to evidence Practice's subordinated security
interest in the Purchased Account's Receivable until the Purchase Price has been
paid.

     Section 6.2.5. Upon expiration or termination of this Agreement for any
reason; (i) all Accounts Receivable purchased by MidSouth shall remain the
property of MidSouth; and (ii) all 

                                       20
<PAGE>
 
Accounts Receivable purchased and not paid for at the termination or expiration
of this Agreement shall be paid for by the 10th day of the following month for
all Purchased Accounts Receivable as of the date of the expiration or
termination date, less the amount of any Service Fees earned by MidSouth at the
termination or expiration pursuant to Section 6.1 of this Agreement.

     Section 6.2.6. In connection with the initial purchase of Accounts
Receivable by MidSouth and pursuant to this Agreement, the Practice will execute
all financing statements or amendments under the UCC (naming MidSouth as secured
party and Lender as assignee) as MidSouth may reasonably request with respect to
any Purchased Accounts Receivable.

     Section 6.2.7. The Practice agrees to cooperate with MidSouth in the
collection of the Purchased Accounts Receivable transferred pursuant to Section
6.2. At the option of and upon the request of MidSouth, the Practice shall
execute any and all documentation necessary for the transfer of amounts
constituting Purchased Accounts Receivables and/or the establishment of the
Lockbox Agreement as follows:

     (a) COLLECTION OF GOVERNMENTAL RECEIVABLES. With respect to payments on
         --------------------------------------
Governmental Receivables, at the request and option of MidSouth, the Practice
agrees that the following procedures shall apply:

     (i) The Practice shall enter into a Lockbox Agreement applicable to
Governmental Receivables in a form acceptable to counsel for MidSouth and in a
form reasonably acceptable to the Practice which shall establish a Governmental
Lockbox Account. The Governmental Lockbox Account shall be an account in the
name of the Practice. All payments with respect to the Practice's Governmental
Receivables are to be made directly to the Governmental Lockbox Account. In the
event MidSouth exercises this option, the Practice shall instruct each Account
Debtor with respect to the Practice's Governmental Receivables to remit all such
payments directly to such Governmental Lockbox Account pursuant to a
Notification Letter. In addition, the Practice shall attach written instructions
to each invoice representing such Governmental Receivables generated subsequent
to the date of this Agreement which will instruct such third-party payor or
Account Debtor that payment under such invoice is to be paid to the Governmental
Lockbox Account. The Practice agrees that it shall not deposit any funds other
than payments on Governmental Receivables into, nor make any withdrawals from,
the Governmental Lockbox Account without the prior written consent of MidSouth.
The Practice further agrees that it shall not during the term of this Agreement
terminate, modify or amend in any manner the Lockbox Agreement applicable to the
Governmental Lockbox Account.

     (ii) In accordance with the Lockbox Agreement pertaining to Governmental
Receivables, the Practice shall instruct the Collecting Bank to transfer
automatically all amounts deposited in Governmental Lockbox Account constituting
good funds to the Disbursement Account in accordance with Section 3.l(b)(2).
The Practice shall have no right or interest in the Disbursement Account. The
Practice shall not, so long as this Agreement has not been terminated pursuant
to Section 10.3 or so long as any Purchased Accounts Receivable remains
outstanding, change or cancel such 

                                       21
<PAGE>
 
automatic transfer order at any time, or, without the prior written consent of
MidSouth, change either the identity of Governmental Lockbox Account or the
instructions to each Account Debtor on the related Governmental Receivable
regarding making payments to such account. Any such action shall be considered a
breach of this Agreement for which MidSouth shall be entitled to all remedies at
Applicable Law and in equity, including obtaining an injunction.

     (iii) The Practice will cooperate with MidSouth and its agents in the
identification of sums deposited into Governmental Lockbox Account, which
cooperation shall continue until all Purchased Accounts Receivable sold
hereunder have been collected.

     (iv) The Practice agrees to pay, on demand, a finance charge equal to the
Finance Charge Rate, on any payment on a Governmental Receivable received by the
Practice that is not deposited in Governmental Lockbox Account within two (2)
business days after receipt by the Practice. Except that the finance charge
shall not apply to payments made on Purchased Accounts Receivables which are
made as part of a cash, check or credit card payment at the time of the delivery
of medical services by the Practice which are remitted to the Practice Account
("Joint Payment"). All Joint Payments shall be allocated and remitted to the
appropriate party on the Settlement Date.

          (b) COLLECTION OF NON-GOVERNMENTAL RECEIVABLES. With respect to
              ------------------------------------------
payments on Non-Governmental Receivables, at the request and option of MidSouth,
the Practice agrees that the following procedures shall apply:

     (i) The Practice, Collecting Bank and Lender (if requested by Lender) shall
enter into a Lockbox Agreement applicable to Non-Governmental Receivables in a
form acceptable to counsel for Practice, MidSouth and Lender, which shall
establish a Non-Governmental Lockbox Account. The Non-Governmental Lockbox
Account shall be an account in the name of the Practice. Practice agrees to
enter into additional agreements with the Lender to acknowledge the Lender's
security interest in the Purchased Accounts Receivable and to set forth the
procedures to account for and reconcile the Non-Governmental Lockbox Account.
All payments with respect to the Practice's Non-Governmental Receivables are to
be made directly to the Non-Governmental Lockbox Account. In the event MidSouth
exercises this option, the Practice shall instruct each Account Debtor with
respect to the Practice's Non-Governmental Receivables to remit all such
payments directly to such Non-Governmental Lockbox Account pursuant to a
Notification Letter. In addition, the Practice shall attach written instructions
to each invoice representing such Non-Governmental Receivables generated
subsequent to the date of this Agreement which will instruct such third-party
payor or Account Debtor that payment under such invoice is to be paid to the
Non-Governmental Lockbox Account. So long as this Agreement has not been
terminated pursuant to Section 10.3, the Practice agrees that it shall not
deposit any funds other than payments on Non-Governmental Receivables into, nor
make any withdrawals from, the Non-Governmental Lockbox Account without the
prior written consent of MidSouth. The Practice further agrees that it shall
not during the term of this Agreement terminate, modify or amend in any manner
the Lockbox Agreement applicable to the Non-Governmental Lockbox Account.

                                       22
<PAGE>
 
     (ii) In accordance with the Lockbox Agreement, Practice shall instruct the
Collecting Bank to transfer all amounts deposited in the Non-Governmental
Lockbox Account constituting good funds to the Disbursement Account in
accordance with Section 3.1(b)(2). So long as this Agreement has not been
terminated pursuant to Section 10.3, or so long as any Purchased Accounts
Receivable remains outstanding, and in any event, during the term of this
Agreement, at any time, or, without the prior written consent of MidSouth, the
Practice shall not change the instructions to each Account Debtor on the related
Non-Governmental Receivable regarding making payments to the Lockbox Account.
Any action shall be considered a breach of this Agreement for which MidSouth
shall be entitled to all remedies under Applicable Law and in equity, including
obtaining an injunction.

     (iii) The Practice will cooperate with MidSouth and its agents in the
identification of sums deposited into the Non-Governmental Lockbox Account,
which cooperation shall continue until all Purchased Accounts Receivable sold
hereunder have been collected.

     (iv) The Practice agrees to pay, on demand, a finance charge equal to the
Finance Charge Rate, on any Non-Governmental Receivable received by the Practice
that is not deposited in the Non-Governmental Lockbox Account within two (2)
business days after receipt by the Practice. Except that the finance charge
shall not apply to payments made on Purchased Accounts Receivables which are
made as part of a cash, check or credit card payment at the time of the delivery
of medical services by the Practice which are remitted to the Practice Account.
All Joint Payments shall be allocated and remitted to the appropriate party on
the Settlement Date.

     (c) PROCEDURES WITHOUT LOCKBOX. It is MidSouth's intention to utilize the
         --------------------------
Governmental Lockbox Account and Non-Governmental Lockbox Account procedure as
provided in Section 6.2.6(a) and (b) unless circumstances change which would
make the Governmental Lockbox Account and Non-Governmental Lockbox Account
procedures inappropriate. The procedures under this subsection (c) for the
collection of Accounts Receivable without a lockbox will not be instituted
without approval of the Management Team. The Practice and MidSouth shall
instruct the Collecting Bank to transfer automatically all amounts constituting
good funds in the account or accounts of the Practice established for the
collection of Governmental Receivables and Non-Governmental Receivables to the
Bank Account established with the Lender pursuant to a standing order in a form
acceptable to MidSouth's legal counsel (the "Bank Account"). In the event
MidSouth exercises this option, the Practice shall instruct each Account Debtor
with respect to the Purchased Accounts Receivable to remit all payments directly
to the Collecting Bank account or accounts pursuant to a Notification Letter. In
addition, the Practice shall attach written instructions to each invoice
representing the Purchased Account Receivable generated subsequent to the date
of this Agreement instructing such third-party payor or Account Debtor that
payment under the invoice is to be paid to the Collecting Bank account or
accounts. So long as this Agreement has not been terminated pursuant to Section
10.3 or so long as any Purchased Accounts Receivable remain outstanding, the
Practice shall not change or cancel such standing order at any time, or, without
the prior written consent of MidSouth, change the instructions to each Account
Debtor on each Governmental Receivable end Nor-Governmental Receivable to make
its payments to such account. Any such action shall be considered a breach of
this Agreement for which MidSouth shall be entitled to all remedies under
Applicable Law and in equity, including obtaining an injunction.

                                       23
<PAGE>
 
     (d) MISDIRECTED PAYMENTS. (i) If after the date of this Agreement, an
         --------------------
Account Debtor shall make a payment on the Purchased Accounts Receivable to a
location other than is provided in the Notification Letter or the Practice
otherwise receives payments on Purchased Accounts Receivable under the terms of
this Agreement ("Misdirected Payments"), the Practice (at its own cost and
expense) shall promptly take all necessary steps to effect collection of the
Misdirected Payment from any other party claiming an interest therein or having
possession thereof and (A) hold the Misdirected Payment in trust for MidSouth,
(B) segregate the Misdirected Payment, (C) use its best efforts not to commingle
the Misdirected Payment with the Practice's own funds or other assets, and (D)
deliver the Misdirected Payment no later than two (2) business days from the day

     SECTION 6.3. EARLY TERMINATION OF PHYSICIAN MEMBERS. The Physician Members
                  --------------------------------------
hereby acknowledge that the terms and conditions of this Agreement are based
upon numerous factors, including the Physician Members continuing to practice
medicine in the future. ln connection therewith, each Physician Member agrees as
follows:

     (a) RETIREMENT. If at any time during the Term hereof, a Physician Member
         ----------                                                           
desires to retire, or assume full-time teaching responsibilities, the Physician
Member shall notify MidSouth in writing at least twelve (12) months prior to the
date of such retirement or start of teaching position; provided, however, that
if such retiring physician elects to, and has located a replacement physician
suitable to the Practice, MidSouth shall waive the remaining months of said
twelve (12) month notice period, and such retirement shall be effective upon
the earlier of twelve (12) months from the date of notice or commencement of the
replacement physician's employment. Upon such retirement or start of the
teaching position, the Physician Member shall have no further obligations under
this Agreement; provided, however, the restrictive covenants provided for under
Article Section 7 shall remain in full force and effect. In fulfilling any such
full-time teaching responsibilities, the Physician Member will be permitted to
attend patients in a manner normal and customary for such faculty position;
provided, however, such services must be incident to the academic/teaching
aspects of the institution, and not incident to the regular examination of
patients for a fee whether billed in the name of the institution or the name of
the attending physician. It is not the intent of the parties to permit a retired
physician to conduct a medical practice through an academic institution.

                                       24
<PAGE>
 
     (b) PHYSICIAN MEMBER CHANGE IN PRACTICE/GROUP AFFILIATION. In the event
         -----------------------------------------------------
that a Physician Member leaves the employment of or terminates his or her
affiliation with the Practice, the terminating Physician Member may join or
establish another group/practice which has or will enter into a service
agreement with MidSouth, subject to any other existing agreements between
Physician Member and Practice. Upon entering into such new service agreement
with MidSouth, the terminating Physician Member shall, except as limited by
separate employment agreements between the Practice and the Physician Members,
be released from any obligation under this Agreement. MidSouth shall have the
right to enter into a new service agreement without satisfying the requirements
of Article 7 hereof. In the event the (i) Practice consents to MidSouth
entering into a new service agreement; (ii) service agreement will not adversely
affect the operations and earnings of MidSouth; and (iii) new group/practice can
satisfy the representations and warranties set forth in Article 12 hereof, then
MidSouth will not unreasonably withhold or refrain from entering into a new
service agreement with the terminating Physician Member's new group/practice.
Except as set forth herein, in the event the Physician Member affiliates with a
new group/practice that is not a party to a service agreement with MidSouth,
then MidSouth, will terminate this Agreement solely with respect to the
terminating Physician Member; provided, however, that the provisions of 
Article 7 hereof shall apply. In the event that MidSouth does not enter into a
new service agreement, then MidSouth shall terminate this Agreement with respect
to the Physician Member, and the terminating Physician Member shall be obligated
as set forth in Article 7 hereof.

     (c) DEATH OR DISABILITY. In the event that a Physician Member dies or
         -------------------
becomes disabled, then the Physician Member shall have no continuing obligations
under this Agreement; provided, however, in the event of disability, the
restrictive covenants described in Article 7 hereof shall remain in full force
and effect.

               ARTICLE 7. RESTRICTIVE COVENANTS AND ENFORCEMENT.
                          -------------------------------------

     MidSouth and the Practice recognize that the benefits each is to receive

medical practice to which the Physicians Members associated with the Practice
devote their full time and attention to the extent of their arrangement with the
Practice. Accordingly, MidSouth and the Practice desire to set forth the
following reasonable restrictions and agreements regarding competition by the
Physicians Members during the term of this Agreement and after the termination
of this Agreement.

     SECTION 7.1. EXCLUSIVE ARRANGEMENT. During the term of this Agreement,

the Practice and the Physician Members agree that neither the Practice nor
Physician Members will enter into any similar agreement with any physician
practice management company or entity.

employment by the Practice during the term of the employment agreement and after
the termination of the employment agreement. Provided also, that the employment
agreements may exclude from the restrictive covenant the employment of Physician
Members in facilities that have historically been deemed emergency room

but was not discovered by MidSouth, beginning upon the date that MidSouth learns
of the violation and so notifies the Practice and/or the Physician Member in
writing.

Article 7. The invalidity or non-enforceability of this Article 7 in any respect
shall not affect the validity or enforceability of the remainder of this Article
7 or of any other provisions of this Agreement.

                                 -----------------------

     SECTION 9.1. INSURANCE TO BE MAINTAINED BY THE PRACTICE. Throughout the
                  ------------------------------------------                
term of this Agreement, subject to the provisions of Section 3.1(m) providing
for malpractice premiums and deductibles to be a Practice Expense, the Practice
shall maintain comprehensive professional liability insurance with limits of not
less than $1,000,000 per claim and with aggregate policy limits of not less than
$3,000,000 per Physician Employee and Physician Extender Employee and a separate
limit for the Practice with the carrier which shall be determined by Practice
upon recommendation by the MidSouth. The Practice shall be responsible for all
liabilities in excess of the limits of the policies, and under no circumstances
shall any excess be deemed a Practice Expense. MidSouth shall have the option,
with Management Team approval, of providing the professional liability insurance
through an alternative program, provided the program meets the requirements of
the Insurance Commissioner of the State. If the Practice's existing professional
liability insurance program is canceled and replaced by a professional liability
insurance program initiated by MidSouth, MidSouth shall pay over to the
Practice any unearned professional liability insurance premiums paid by the
Practice to the extent the Practice's carrier pays the amounts to MidSouth. Any
insurance program for the Practice shall include director and officer liability
insurance for the Practice, and the cost of the coverages shall be a Practice
Expense.

     SECTION 9.2. INSURANCE TO BE MAINTAINED BY MIDSOUTH. Throughout the term of
                  --------------------------------------

Expense, comprehensive general liability and property insurance covering the
Practice premises and operations.

     SECTION 9.3. TAIL INSURANCE COVERAGE. Tail insurance coverage shall be
                  -----------------------

     9.3.1. The Practice will cause each Physician Employee associated with the
Practice to enter into an agreement with the Practice that upon termination of
the physician's relationship with the Practice, for any reason, tail insurance
coverage will be purchased by the individual physician to the extent that it can
not be purchased by the Practice. The provisions may be contained in employment
agreements, restrictive covenant agreements or other agreements entered into by
the Practice and the Physician Employees, and the Practice hereby covenants with
MidSouth to enforce the provisions relating to the tail insurance coverage or to
provide the coverage, which will be a Practice Expense.

                                       30
<PAGE>
 
     9.3.2. The Practice shall obtain continuing liability insurance under
either a tail policy or an acts policy with the same limits and deductibles as
the comprehensive professional liability insurance at the time of the
termination of this Agreement pursuant to Article 10, which will not be a
Practice Expense.

     SECTION 9.4. ADDITIONAL INSURED. The Practice and MidSouth agree to use
                  ------------------
their reasonable best efforts to have each other named as an additional insured
on the other's respective professional liability insurance programs, which will
be a Practice Expense.

     SECTION 9.5. INDEMNIFICATION.
                  ----------------

     9.5.1. The Practice Indemnification.
            ----------------------------

     (a) The Practice shall indemnify, hold harmless and defend MidSouth, its
officers, directors, Members and employees, from and against any and all
liability, loss, damage, claim, causes of action, and expenses (including
reasonable attorneys' fees), to the extent not covered by insurance in the name
of the Practice, caused or asserted to have been caused, directly or indirectly,
by or as a result of the performance of medical services or the performance of
any intentional acts, negligent acts or omissions by the Practice and/or its
Members, agents, employees and/or subcontractors (other than MidSouth or any
other party engaged by MidSouth) during the term hereof, or as a result of a
breach of the representations and warranties contained in Article 12 of this
Agreement or a breach of any covenant in Article 14 of this Agreement.

     (b) The Practice shall not be liable to MidSouth for any claims under
Section 9.5.1(a) above until the claims exceed in the aggregate S25,000.00 that
would otherwise be subject to indemnification under said provisions, and then
only for the amount by which the claims exceed $25,000.00.

     9.5.2. MidSouth Indemnification. MidSouth shall indemnify, hold harmless
            ------------------------
and defend the Practice, its officers, Members, directors and employees, from
and against any and all liability, loss, damage, claim, causes of action, and
expenses (including reasonable attorneys' fees), to the extent not covered by
insurance in the name of MidSouth, caused or asserted to have been caused,
directly or indirectly, by or as a result of the performance of any intentional
acts, negligent acts or omissions by MidSouth and/or its Members, agents,
employees and/or subcontractors (other than the Practice) during the term of
this Agreement or as a result of a breach of the representations and warranties
contained in Article 13 of this Agreement. In addition, MidSouth shall
indemnify, hold harmless and defend the Practice, its officers, Members,
directors and employees, from and against any and all liability, loss, damage,
claim, causes of action, and expenses (including reasonable attorneys' fees)
caused by any claim against the Practice relating to liabilities of the Practice
assumed by MidSouth as a result of the Exchange which were disclosed by the
Practice in the Exchange Agreement and for which the Practice does not have an
obligation to indemnify MidSouth as provided above.

     9.5.3. Indemnification Payment Escrow. In the event that either party makes
            ------------------------------
a claim for indemnification under either the Exchange Agreement or this
Agreement (the "Indemnified Party"), 

                                       31
<PAGE>
 
then the party who must provide indemnity (the "Indemnifying Party"), shall have
the right, to the extent it owes indemnifications, to pay amounts owed to the
Indemnified Party under the Exchange Agreement or this Agreement into an escrow
account (established pursuant to an escrow agreement to be agreed upon by the
parties) to be held by the escrow agent in an interest bearing account until a
determination by either (i) the parties, (ii) a court of proper jurisdiction or
(iii) an agreed upon panel of arbitrators, has been made regarding the
Indemnified Party's right to indemnification. In the event that the Indemnified
Party is entitled to indemnification, then such escrowed funds shall be paid to
the Indemnified Party in partial or complete satisfaction of such
indemnification obligation. Any excess funds remaining in the escrow account
after the payment of the indemnification obligation or any funds held in escrow
account if it is determined that no indemnification obligation is owed shall be
paid to the Indemnifying Party.

                       ARTICLE 10. TERM AND TERMINATION.

     SECTION 10.5. ACTIONS AFTER TERMINATION. Upon termination of this
                   -------------------------
Agreement by either party, the Practice (and/or its Physician Members) shall:

     (a) Purchase from MidSouth at book value all intangible assets set forth on
the Opening Balance Sheet, as adjusted through the last day of the month most
recently ended prior to the date of the termination or expiration to reflect
amortization or depreciation of the "service agreement costs" and intangibles in
accordance with GAAP if terminated by MidSouth or upon the expiration of this
Agreement. If the Agreement is terminated by Practice for MidSouth's breach of
the Agreement, all intangible assets shall be repurchased at the fair market
value;

     (b) Purchase all improvements, additions or leasehold improvements to
Practice Facilities which have been made by MidSouth and which relate solely to
the performance of its obligations under this Agreement at book value;

     (c) Assume all debt and all contracts, payables incurred as Practice
Expenses and leases which are obligations of MidSouth and which relate
principally to the performance of its obligations under this Agreement or the
properties subleased by MidSouth;

     (d) Purchase from MidSouth at book value all of the equipment acquired in
the Exchange, including all replacements and additions thereto made by MidSouth
pursuant to the performance of its obligations under this Agreement, and all
other assets, including inventory, Purchased Accounts Receivable and supplies,
tangibles and intangibles, set forth on the Opening Balance Sheet as adjusted
through the last day of the month most recently ended prior to the date of the
termination or expiration in accordance with GAAP to reflect operations of the

and other adjustments of assets shown on the Opening Balance Sheet; and

     (e) Prior to any initial public offering of MidSouth's Common Stock or
MidSouth's merger into publicly traded company, endorse in blank and deliver to
MidSouth all shares of common stock and all debt instruments, whether or not
convertible into common stock of MidSouth acquired by Physician Members or
Practice in the merger for a credit of five (5) dollars per share. Subsequent to
any initial public offering of MidSouth's Common Stock or MidSouth's merger into
a publicly traded company, Member Physicians or Practice shall have the option
of endorsing in blank and delivering the amount of publicly traded stock at the
value on the transaction date or in the alternative to pay cash equal to the

of a termination by the Practice pursuant to Section 10.3 in which case Practice
shall retain any stock received as part of the Exchange.

     SECTION 10.6. CLOSING OF REPURCHASE BY THE PRACTICE AND EFFECTIVE DATE OF
                   -----------------------------------------------------------
TERMINATION. The Practice shall pay cash to repurchase the assets (the
- -----------
"Repurchase Price"); provided, however, prior to an initial public offering of
the common stock of MidSouth, the Practice shall receive a credit against the
Repurchase Price of a sum equal to the price per share of the common stock of
MidSouth received by the Physician Members of the Practice in the Exchange times
the number of shares of common stock of MidSouth that the Physician Members
received in the Exchange.

                                       34
<PAGE>
 
Subsequent to an initial public offering, the Repurchase Price shall be all
cash. The amount of the Repurchase Price shall be reduced by the amount of debt
and liabilities of MidSouth assumed by the Practice and shall also be reduced by
any payment MidSouth has failed to make under this Agreement. The Practice and
any physician associated with the Practice shall execute all documents as may be
required to assume the liabilities set forth in Section 10.5, to remove MidSouth
from any liability with respect to the repurchased assets and with respect to
any property leased or subleased by MidSouth, and to carry out the transactions
contemplated herein. The closing date for the repurchase shall be determined by
the Practice, but shall in no event occur later than ninety (90) days from the
date of the notice of termination. The termination of this Agreement shall
become effective upon the closing of the sale of the assets. On the date of
termination, but only in the event that the termination of the Agreement was the
result of a breach by MidSouth, the Practice and the Members shall be released
from the restrictive covenants provided for in Article 7. MidSouth shall have
the right, in its sole and absolute discretion, to waive the repurchase
requirements of the Practice, in which event, the termination of this Agreement
shall become effective upon the execution and delivery of the waiver. From and
after any termination, each party shall provide the other party with reasonable
access to books and records then owned by it to permit the requesting party to
satisfy reporting and contractual obligations which may be required of it.
Except as otherwise provided herein, the restrictive covenants contained in
Article 7 shall survive the termination of this Agreement.

                ARTICLE 11. INTELLECTUAL PROPERTY AND RECORDS.
                            ---------------------------------

     SECTION 11.1. PROPRIETARY INFORMATION. The Practice acknowledges that
                   -----------------------
MidSouth possess significant proprietary and confidential know-how, technology
and business information, including but not limited to, utilization protocols,
practice guidelines and proprietary management software and data ("Proprietary
Information"), which MidSouth has developed and will continue to develop on its
own, in its relationship with vendors, practitioner groups, integrated delivery
systems and other providers. The Practice and MidSouth acknowledge that one of
their mutual objectives is the development of Proprietary Information to be used
in connection with MidSouth's operations or which MidSouth intends to use or
license in its relationship with third parties, including other medical groups,
integrated delivery systems and other providers. In addition, the Practice
acknowledges that as of the Closing Date, by virtue of execution and delivery of
the Exchange Agreement, MidSouth will have acquired all of the Practice's
existing Proprietary Information, excluding patient medical records. Therefore,
the parties agree that MidSouth shall own all new Proprietary Information, as
well as existing Proprietary Information, excluding patient medical records,
regardless of whether the new Proprietary Information is developed by one or
more physicians in the Practice or Affiliates. The Practice agrees to execute
and deliver such documentation as may be requested by MidSouth from time to time
to evidence such ownership. During the term of this Agreement, MidSouth shall
license and provide access to all existing Proprietary Information to the
Practice.

     SECTION 11.2. OWNERSHIP OF MIDSOUTH'S BUSINESS RECORDS AND SYSTEMS. All
                   ----------------------------------------------------     
business records, information, software and systems of MidSouth relating to the
provision of its services under this Agreement shall remain the property of
MidSouth and may be removed by MidSouth upon

                                       35
<PAGE>
 
any termination of this Agreement; provided, however, that the Practice shall be
entitled, upon reasonable written request, to access such records and make
copies or extracts thereof to the extent necessary to prosecute or defend
against any tax or other liabilities imposed on the Practice by any Governmental
Authority or other party.

     SECTION 11.3. MAINTENANCE AND ACCESS OF RECORDS. Except as otherwise
                   ---------------------------------                     
provided in this Agreement, the parties shall safeguard all records maintained
by them pursuant to this Agreement for a period of time specified by the
Management Team from the date of the last activity recorded in such records. In
particular, the parties agree, to the extent necessary to permit receipt of
reimbursement for services by the Practice, to make available to the Secretary
of the United States Department of Health and Human Services, the Comptroller
General at the General Accounting Office, or their authorized representatives,
any books, documents and records in their possession relating to the nature and
extent of the costs of services hereunder for a period of four (4) years after
the provision of such services. Each party further agrees that, if it contracts
with any third party to provide services that are valued in excess of $10,000,
it shall require the contracting party to comply with the requirements of the
previous sentence. During the term of this Agreement, and thereafter, the
Practice or its designee shall have reasonable access during normal business
hours to the Practice's and MidSouth's financial and accounting, including, but
not limited to, records of collections, expenses and disbursements as kept by
MidSouth in performing MidSouth's obligations under this Agreement, and the
Practice may copy any or all records at its expense. Nothing in this Section
11.3 constitutes the waiver of any attorney-client privilege, and neither party
shall be required hereunder to give the other party documents if, as a result,
an existing attorney-client privilege would be waived.

     SECTION 11.4. PATIENT RECORDS. Upon termination of this Agreement, the
                   ---------------
Practice shall retain all patient medical records maintained by the Practice or
MidSouth in the name of the Practice.

     SECTION 11.5. ACCESS TO RECORDS. During the term of this Agreement, and
                   -----------------
thereafter, the Practice or its designee shall have reasonable access during
normal business hours to the Practice's and MidSouth's financial records,
including, but not limited to, records of collections, expenses and
disbursements as kept by MidSouth in performing MidSouth's obligations under
this Agreement, and the Practice may copy any or all records at its expense.

<PAGE>
 
     12.10.10. Except with respect to Governmental Receivables, the insurance
policy, Contract or other instrument obligating an Account Debtor to make

Schedule 12.10.10, (ii) has been duly authorized by the Practice and to the
knowledge of the Practice has been duly authorized by the Account Debtor and,

to the consideration received by the Member under the Asset Exchange Agreement.
It is the intent of this Section 12.11 that once MidSouth has recovered the
Purchase Price received by a Member from the Member (whether the basis for such
recovery is the inaccuracy of a representation in this Agreement, the inaccuracy
of a representation in the Exchange Agreement, or the breach of the Exchange
Agreement or any combination of the above), MidSouth will have no further rights
or remedies against the Member.

     SECTION 12.12. EXHIBITS. All the facts recited in Exhibits annexed hereto
                    --------

                                      -------------

     SECTION 15.1. ASSIGNMENT. MidSouth shall have the right to assign without
                   ----------
the consent of the Practice all of its rights hereunder to any person, firm or
corporation (i) under common control with MidSouth, (ii) to any lending
institution, for security purposes or as collateral, from which MidSouth obtains
financing, (iii) that is an affiliate of MidSouth, including, but not limited
to, a parent, subsidiary, or brother-sister corporation, or (iv) that merges,
reorganizes, or otherwise consolidates with MidSouth and further agrees that
upon receipt of notice from such assignee, the Practice shall pay to the
assignee or cause to be paid to the assignee all amounts due and payable to
MidSouth pursuant to this Agreement. Without limiting the foregoing, the
Practice acknowledges that, as collateral for certain obligations, MidSouth has
assigned all of its rights hereunder to a Lender as Agent (the "Agent") for
itself and other banks and institutional lenders from time to time (collectively
the "Banks") and has granted the Agent for the benefit of the Banks a lien and
security interest upon all real and personal property owned by MidSouth
("Pledged Assets"). As an inducement for the Banks to extend or continue the
extension of credit to MidSouth, the Practice (i) acknowledges that the
collateral assignment to the Agent covers all rights of MidSouth hereunder,
including, but not limited to, rights arising from warranties and
representations made by the Practice, rights to enforce covenants made by the
Practice, and rights to receive all payments due MidSouth; (ii) agrees to regard
the Agent as the owner of any and all of the assigned rights upon written notice
to the Practice of this election from the Agent; (iii) agrees that neither the
Agent nor any of the Banks has obligation for the performance of the duties of
MidSouth hereunder, and shall not assume any such duty by the exercise of rights
as a secured lender; (iv) agrees to give the Agent written notice of any
material Default hereunder on MidSouth's part at the address provided by the
Agent in writing to Practice, and to allow cure periods as provided in Section
10.3 thereafter for the cure of Default before the Practice terminates this
Agreement; (v) agrees that the rights of the Practice under this Agreement,
including, but not limited to, the right to the use of the Pledged Assets, are
and shall be junior to any security interest that the Agent and the Banks, their
successors or assigns may have in the Pledged Assets at any time; (vi) agrees
that the benefits of the above undertakings in favor of the Agent and Banks
shall further extend to all successors and assigns of the Agent and Banks,
provided that any notices given by the Practice under this Section 15.1 shall be
given to the Agent at the foregoing address unless the Practice has received
written notice of a change thereof; and (vii) agrees that this Section 15.1 may
not be modified, and no provision of this Section 15.1 may be waived, absent the
written approval of the Agent and Banks. Further, if a majority of the Members
of MidSouth entitled to vote on a sale of all of the assets or substantially all
of the assets or common stock of MidSouth authorize the sale or transfer of all
or substantially all of the assets or common

                                       44
<PAGE>
 
stock of MidSouth to a third party (the "Acquiring Party"), this Agreement shall
be deemed automatically assigned and transferred to the Acquiring Party without
the necessity of obtaining the consent of the Practice. Except as set forth
above, neither MidSouth nor the Practice shall have the right to assign their
respective rights and obligations hereunder without the written consent of the
other party.

     SECTION 15.2. THIS AGREEMENT. This Agreement sets forth the entire
                   --------------
agreement of the parties with respect to the subject matter hereof and it
supersedes and discharges all prior agreements (written or oral) and
negotiations and all contemporaneous oral agreements concerning the subject
matter. There are no oral conditions precedent to the effectiveness of this

by the Management Team. The Practice hereby appoints MidSouth to be its true and
lawful attorney-in-fact to incur all expenses and to perform all functions in
the name and on behalf of the Practice pursuant to the policies and procedures
adopted by the Management Team. MidSouth will have no authority, directly or
indirectly, to perform, and will not perform, any medical function. MidSouth
may, however, advise the Practice to the relationship between the Practice's
performance of medical functions and the overall administrative and business
functioning of the Practice. To the extent that a MidSouth employee assists
Physician Employees in performing medical functions, such employees shall be
subject to the professional direction and supervision of Physician Employees and
in the performance of such medical functions shall not be subject to any
direction or control by, or liability to, MidSouth, except as may be
specifically authorized in writing by MidSouth.

     (b)(1) Billing and Collecting. MidSouth shall, on behalf of the Practice,
            ------------------------

Receivable resulting from billing in the Practice's name and on its behalf;

Practice, to enforce the rights of the Practice as creditors under any Contract
or in connection with the rendering of any service, and to contest adjustments

courtesies and other activities that do not generate a collectible fee shall be
performed in a reasonable and consistent manner approved by the Management Team.

account for the Practice, which is the Practice Account. The Practice Account
shall be controlled solely by the Practice. The parties acknowledge and agree
that in the event that the mix between Accounts Receivable and non-Accounts
Receivable receipts is altered to the point where proceeds from the Accounts
Receivable are not sufficient to pay for the Service Fee, the parties will
establish mutually agreeable terms to allow MidSouth access to the Practice
Account to pay the Service Fee. The Practice shall use the monies in the
Practice Account to pay all the Excluded Expenses. MidSouth will transfer monies
to the Practice Account to remit, on a monthly basis, the Purchase Price for the

              ------------------------                                         
the properties and facilities owned by the Practice on the date of this
Agreement and/or more fully described in Schedule 1.1.47 attached hereto (the
"Practice Facilities "), and shall pay the lease payments, costs of repairs,
maintenance and improvements, utility (telephone, electric, gas, water)
expenses, normal janitorial services, refuse disposal and all other costs and
expenses reasonably incurred in conducting operations of the Practice during the
term of this Agreement. All of these costs shall be Practice Expenses; however,
the costs of debt service on any real property owned by the Practice shall not
be a Practice Expense. Nothing contained herein is intended to require the
MidSouth to provide the foregoing services if the services are required to be
provided by the landlord under a lease for a specific property. The Management
Team shall make all determinations regarding the condition, use and needs for
the offices, facilities and improvements. The Management Team shall determine

Practice during the term of this Agreement. The Practice shall not enter into
any new leases or subleases or agree to amend any currently existing lease or
sublease without the express written consent of the Management Team. The right

premises, shall not constitute an assignment of any of the Practice's rights
under existing leases, and shall not be construed as an assignment or other
transfer of any rights of the Practice to its owned property or any rights under
any existing leases.

                           ARTICLE 6. COMPENSATION.
                                     -------------

(10%) of Practice Net Revenue plus the amount of Practice Expenses incurred by
MidSouth. Physician Shareholder hereby guarantees that Practice shall pay a
minimum annual Service Fee of Sixty Thousand Dollars ($60,000) for each year up

Service Fee guaranteed shall increase to $75,000 if and when Dr. Rebecca Rezaei,
M.D. commences full-time employment by the Practice during the first year of the
Term. The guaranteed minimum annual Service Fee for the first year of the Term

<PAGE>
 
     (b) The amounts to be paid to MidSouth under this Section 6.1 shall be
payable monthly and shall reflect the Service Fee for payments deposited into
the Practice Account, at the time that MidSouth pays the Practice for the
Purchased Accounts Receivable as described in Section 6.2 below. The Practice
shall receive the Purchase Price as defined below, plus other payments (less any
applicable Service Fee) received by MidSouth to the extent such payments are not
reflected as Accounts Receivable of the Practice. The amount of the Service Fee
payable shall be estimated based upon the previous month's operating results of
the Practice. Any amounts due to MidSouth as a result of a Monthly Adjustment to
the Service Fee shall be paid by the Practice on the next succeeding date on
which MidSouth purchases Accounts Receivable from the Practice. The Yearly
Adjustments to the Service Fee and any amount owed shall be calculated and paid
within ninety (90) days following date upon which the Practice receives notice
of the amount of the Yearly Adjustment. The Physician Shareholder acknowledges
and agrees that he is a party, individually, to this Agreement and that if the
Practice fails to pay the Service Fees herein described, MidSouth shall have the
right to collect the Service Fees from the Physician Shareholder. The Management
Team shall establish the relative amount of the Service Fees applicable to each
Physician Shareholder.

     SECTION 6.2. PURCHASE OF ACCOUNTS RECEIVABLE AND OTHER PAYMENT
                  -------------------------------------------------

     Section 6.2.1. During the Term of this Agreement, the Practice hereby
agrees to sell and assign to MidSouth and MidSouth agrees to purchase, all of
the Practice's Accounts Receivable each month ("Purchased Accounts Receivable").
Purchased Accounts Receivable shall not include, and MidSouth shall not
purchase, any cash, checks or credit card receivables (not related to previously
Purchased Accounts Receivable) received by the Practice, all of which shall be
deposited into the Practice Account and calculated as part of the Practice Net
Revenues.

     Section 6.2.2. The purchase price for the Purchased Accounts Receivable
(the "Purchase Price") will be equal to the face amount of the Accounts
Receivable recorded each month in a final billable form, less (i) any non-
allowed contractual adjustments imposed by Third Party Payor Programs, and (ii)
any reserve for uncollectible Accounts Receivable. The Purchase Price will be
estimated each month to take into account contractual adjustments and
uncollectible Accounts Receivable based on the most recently completed six (6)
month historical experience of the Practice or the predecessor of the Practice,
calculated on a rolling basis, as determined by MidSouth. It is the intent of
the parties that the Purchase Price reflect the actual net realizable value of
the Accounts Receivable. 

     Section 6.2.3. The Practice will sell all Accounts Receivable to MidSouth
and each purchase will be deemed to be made on the day after which the Accounts
Receivable are created. MidSouth shall pay the estimated Purchase Price for the
Purchased Accounts Receivable no later than the 15th day of each month
following the month in which the Purchased Accounts Receivable are created (the
"Settlement Date"). In the event the Yearly Adjustments to the Purchase Price
indicate that MidSouth has underpaid the Practice for the Purchased Accounts
Receivable, MidSouth shall remit the amount of the underpayment to the Practice
on the next date on which MidSouth purchases Accounts Receivable from the
Practice. In the event the Yearly Adjustments to the Purchase Price indicate
that MidSouth has overpaid for Purchased Accounts Receivable, the Practice shall

                                       19
<PAGE>
 
remit to MidSouth the amount of such overage on the next date on which MidSouth
purchases Accounts Receivable from the Practice. MidSouth shall pay the Practice
for all Purchased Accounts Receivable by check, wire transfer or intrabank
transfer to the Practice Account. The purchase of Accounts Receivable shall be
evidenced by the Practice sending MidSouth (i) a copy of each invoice with
respect to each third-party payor on the Purchased Accounts Receivable; and (ii)
any other information or documentation (including all required Uniform
Commercial Code ("UCC") releases or financing statements) MidSouth may
reasonably need to identify the Purchased Accounts Receivable and obtain payment
from the Account Debtors; provided that the failure to send any documentation
shall not affect the obligation of the Practice to sell the Purchased Accounts
Receivable or MidSouth to purchase the Purchased Accounts Receivable. As
consideration for the acquisition of the Purchased Accounts Receivable by
MidSouth pursuant to this Section 6.2, MidSouth promises to pay and shall be
obligated to pay the Purchase Price for the Purchased Accounts Receivable at the
time and in the manner provided above. To the extent permissible by Applicable
Law, the Practice will be deemed to have sold to MidSouth all of the Practice's
right, title and interest in the Purchased Accounts Receivable and in any
proceeds thereof, and MidSouth will be the sole and absolute owner thereof and
will own all of the Practice's rights and remedies represented by the Purchased
Accounts Receivable (including, without limitation, rights to payment from the
respective Account Debtors on the Purchased Accounts Receivable), and MidSouth
will have obtained all of the Practice's rights under all guarantees,
assignments and securities with respect to all of the Purchased Accounts
Receivable.

     Section 6.2.4. Upon expiration or termination of this Agreement for any
reason; (i) all Accounts Receivable purchased by MidSouth shall remain the
property of MidSouth; and (ii) all Accounts Receivable purchased and not paid
for at the termination or expiration of this Agreement shall be paid for by the
15th day of the following month for all Purchased Accounts Receivable as of the
date of the expiration or termination date, less the amount of any Service Fees
earned by MidSouth at the termination or expiration pursuant to Section 6.1 of
this Agreement.

     Section 6.2.5. In connection with the initial purchase of Accounts
Receivable by MidSouth and pursuant to this Agreement, the Practice will execute
all financing statements or amendments under the UCC (naming MidSouth as secured
party and Lender as assignee) as MidSouth may reasonably request with respect to
any Purchased Accounts Receivable.

     Section 6.2.6. The Practice agrees to cooperate with MidSouth in the
collection of the Purchased Accounts Receivable transferred pursuant to Section
6.2. At the option of and upon the request of MidSouth, the Practice shall
execute any and all documentation necessary for the transfer of amounts
constituting Purchased Accounts Receivables and/or the establishment of the
Lockbox Agreement as follows:

     (A) COLLECTION OF GOVERNMENTAL RECEIVABLES. With respect to payments on
         --------------------------------------                             
Governmental Receivables, at the request and option of MidSouth, the Practice
agrees that the following procedures shall apply:

                                       20
<PAGE>
 
     (i) The Practice shall enter into a Lockbox Agreement applicable to
Governmental Receivables in a form acceptable to counsel for MidSouth and in a
form reasonably acceptable to the Practice which shall establish a Governmental
Lockbox Account. The Governmental Lockbox Account shall be an account in the
name of the Practice. All payments with respect to the Practice's Governmental
Receivables are to be made directly to the Governmental Lockbox Account. In the
event MidSouth exercises this option, the Practice shall instruct each Account
Debtor with respect to the Practice's Governmental Receivables to remit all such
payments directly to such Governmental Lockbox Account pursuant to a
Notification Letter. In addition, the Practice shall attach written instructions
to each invoice representing such Governmental Receivables generated subsequent
to the date of this Agreement which will instruct such third-party payor or
Account Debtor that payment under such invoice is to be paid to the Governmental
Lockbox Account. So long as this Agreement has not been terminated pursuant to
Section 10.3 or so long as any Purchased Accounts Receivable remain outstanding,
the Practice agrees that it shall not deposit any funds other than payments on
Governmental Receivables into, nor make any withdrawals from, the Governmental
Lockbox Account without the prior written consent of MidSouth. The Practice
further agrees that it shall not during the term of this Agreement terminate,
modify or amend in any manner the Lockbox Agreement applicable to the
Governmental Lockbox Account.

     (ii) In accordance with the Lockbox Agreement pertaining to Governmental
Receivables, the Practice shall instruct the Collecting Bank to transfer
automatically on a daily basis all amounts deposited in Governmental Lockbox
Account constituting good funds to the Disbursement Account in accordance with
Section 3.1(b)(2). The Practice shall have no right or interest in the
Disbursement Account. The Practice shall not, so long as any Purchased Accounts
Receivable remains outstanding, change or cancel such automatic transfer order
at any time, or, without the prior written consent of MidSouth, change either
the identity of Governmental Lockbox Account or the instructions to each Account
Debtor on the related Governmental Receivable regarding making payments to such
account. Any such action shall be considered a breach of this Agreement for
which MidSouth shall be entitled to all remedies at Applicable Law and in
equity, including obtaining an injunction.

     (iii) The Practice will cooperate with MidSouth and its agents in the
identification of sums deposited into Governmental Lockbox Account, which
cooperation shall continue until all Purchased Accounts Receivable sold
hereunder have been collected.

     (iv) The Practice agrees to pay, on demand, a finance charge equal to the
Finance Charge Rate, on any payment on a Governmental Receivable received by the
Practice that is not deposited in Governmental Lockbox Account within two (2)
business days after receipt by the Practice.

          (B) COLLECTION OF NON-GOVERNMENTAL RECEIVABLES. With respect to
              -------------------------------------------               
payments on Non-Governmental Receivables, at the request and option of MidSouth,
the Practice agrees that the following procedures shall apply:

                                       21
<PAGE>
 
     (i) Prior to the acquisition of the Purchased Accounts Receivable,
MidSouth, the Collecting Bank and Lender (if requested by Lender) shall enter
into the Lockbox Agreement applicable to Non-Governmental Receivables in a form
acceptable to counsel for MidSouth and MidSouth shall establish the Non-
Governmental Lockbox Account. All payments with respect to the Non-Governmental
Receivables are to be made directly to the Non-Governmental Lockbox Account. If
MidSouth exercises its option herein, the Practice shall instruct each Account
Debtor with respect to the Practice's Non-Governmental Receivables to remit all
payments directly to the Non-Governmental Lockbox Account pursuant to a
Notification Letter. In addition, the Practice shall attach written instructions
to each invoice representing a Non-Governmental Receivable generated subsequent
to the date of this Agreement instructing such third-party payor or Account
Debtor that payment under the invoice is to be paid to the Non-Governmental
Lockbox Account.

     (ii) In accordance with the Lockbox Agreement, Practice shall instruct the
Collecting Bank to transfer automatically on a daily basis all amounts deposited
in the Non-Governmental Lockbox Account constituting good funds to the
Disbursement Account in accordance with Section 3.1(b)(2). The Practice shall
not, so long as any Purchased Accounts Receivable remains outstanding, and in
any event, during the term of this Agreement, at any time, or, without the prior
written consent of MidSouth, change the instructions to each Account Debtor on
the related Non-Governmental Receivable regarding making payments to the Lockbox
Account. Any action shall be considered a breach of this Agreement for which
MidSouth shall be entitled to all remedies under Applicable Law and in equity,
including obtaining an injunction.

     (iii) The Practice will cooperate with MidSouth and its agents in the
identification of sums deposited into the Non-Governmental Lockbox Account,
which cooperation shall continue until all Purchased Accounts Receivable sold
hereunder have been collected.

     (iv) The Practice agrees to pay, on demand, a finance charge equal to the
Finance Charge Rate, on any Non-Governmental Receivable received by the Practice
that is not deposited in the Non-Governmental Lockbox Account within two (2)
business days after receipt by the Practice.

     (C) PROCEDURES WITHOUT LOCKBOX. It is MidSouth's intention to utilize the
         ----------------------------                                         
Governmental Lockbox Account and Non-Governmental Lockbox Account procedure as
provided in Section 6.2.6(a) and (b) unless circumstances change which would
make the Governmental Lockbox Account and Non-Governmental Lockbox Account
procedures inappropriate. The procedures under this subsection (c) for the
collection of Accounts Receivable without a lockbox will not be instituted
without approval of the Management Team. The Practice and MidSouth shall
instruct the Collecting Bank to transfer automatically all amounts constituting
good funds in the account or accounts of the Practice established for the
collection of Governmental Receivables and Non-Governmental Receivables to the
bank account established with the Lender pursuant to a standing order in a form
acceptable to MidSouth's legal counsel (the "Bank Account"). In the event
MidSouth exercises this option, the Practice shall instruct each Account Debtor
with respect to the Purchased Accounts Receivable to remit all payments directly
to the Collecting Bank account or accounts pursuant to a Notification Letter. In
addition, the Practice shall attach written instructions to each invoice

                                       22

<PAGE>
 
representing the Purchased Account Receivable generated subsequent to the date
of this Agreement instructing such third-party payor or Account Debtor that
payment under the invoice is to be paid to the Collecting Bank account or
accounts. The Practice shall not, so long as any Purchased Accounts Receivable
remain outstanding, change or cancel such standing order at any time, or,
without the prior written consent of MidSouth, change the instructions to each
Account Debtor on each Governmental Receivable and Non-Governmental Receivable
to make its payments to such account. Any such action shall be considered a
breach of this Agreement for which MidSouth shall be entitled to all remedies
under Applicable Law and in equity, including obtaining an injunction.

     (D) MISDIRECTED PAYMENTS. (i) If after the date of this Agreement, an
         --------------------
Account Debtor shall make a payment on the Purchased Accounts Receivable to a
location other than is provided in the Notification Letter or the Practice
otherwise receives payments on Purchased Accounts Receivable under the terms of
this Agreement ("Misdirected Payments"), the Practice (at its own cost and
expense) shall promptly take all necessary steps to effect collection of the
Misdirected Payment from any other party claiming an interest therein or having
possession thereof and (A) hold the Misdirected Payment in trust for MidSouth,
(B) segregate the Misdirected Payment, (C) use its best efforts not to commingle
the Misdirected Payment with the Practice's own funds or other assets, and (D)
deliver the Misdirected Payment no later than two (2) business days from the day
of receipt to the Collecting Bank account or accounts, as applicable.

     (ii) The Practice agrees to pay, on demand, the Finance Charge Rate on any
Misdirected Payment received by the Practice that is not deposited in the
appropriate account within two (2) business days after receipt by the Practice.

     (e) All Purchased Accounts Receivable of the Practice pursuant to this
Section 6.2 hereof will, as the Purchased Accounts Receivable are purchased, be
treated as Practice Revenues for accounting and financial purposes.

     SECTION 6.3. EARLY TERMINATION OF PHYSICIAN SHAREHOLDER. The Physician
                  ------------------------------------------
Shareholder hereby acknowledges that the terms and conditions of this Agreement
are based upon numerous factors, including the Physician Shareholder continuing
to practice medicine in the future. In connection therewith, the Physician
Shareholder agrees as follows:

     (A) RETIREMENT. If at any time during the Term hereof, the Physician
         ----------                                                      
Shareholder desires to retire, or assume full-time teaching responsibilities,
the Physician Shareholder shall notify MidSouth in writing at least twelve (12)
months prior to the date of such retirement or start of teaching position;
provided, however, that if such retiring physician elects to, and has located a
replacement physician suitable to the Practice, MidSouth shall waive the
remaining months of said twelve (12) month notice period, and such retirement
shall be effective upon the earlier of twelve (12) months from the date of
notice or commencement of the replacement physician's employment. Upon such
retirement or start of the teaching position, the Physician Shareholder shall
have no further obligations under this Agreement; provided, however, the
restrictive covenants provided for under Article Section 7 shall remain in full
force and effect. In fulfilling any such full-time teaching

                                       23
<PAGE>
 
responsibilities, the Physician Shareholder will be permitted to attend patients
in a manner normal and customary for such faculty position; provided, however,
such services must be incident to the academic/teaching aspects of the
institution, and not incident to the regular examination of patients for a fee
whether billed in the name of the institution or the name of the attending
physician. It is not the intent of the parties to permit a retired physician to
conduct a medical practice through an academic institution.

     (B) PHYSICIAN SHAREHOLDER CHANGE IN PRACTICE/GROUP AFFILIATION. In the
         ----------------------------------------------------------
event that a Physician Shareholder leaves the employment of or terminates his or
her affiliation with the Practice, the terminating Physician Shareholder may
join or establish another group/practice which has or will enter into a service
agreement with MidSouth, subject to any other existing agreements between
Physician Shareholder and Practice. Upon entering into such new service
agreement with MidSouth, the terminating Physician Shareholder shall, except as
limited by separate employment agreements between the Practice and the Physician
Shareholder, be released from any obligation under this Agreement. MidSouth
shall have the right to enter into a new service agreement without satisfying
the requirements of Article 7 hereof. In the event the (i) Practice
consents to MidSouth entering into a new service agreement; (ii) service
agreement will not adversely affect the operations and earnings of MidSouth; and
(iii) new group/practice can satisfy the representations and warranties set
forth in Article 12 hereof, then MidSouth will not unreasonably withhold or
refrain from entering into a new service agreement with the terminating
Physician Shareholder's new group/practice. Except as set forth herein, in the
event the Physician Shareholder affiliates with a new group/practice that is not
a party to a service agreement with MidSouth, then MidSouth, will terminate this
Agreement solely with respect to the terminating Physician Shareholder;
provided, however, that the provisions of Article 7 hereof shall apply. In the
event that MidSouth does not enter into a new service agreement, then MidSouth
shall terminate this Agreement with respect to the Physician Shareholder, and
the terminating Physician Shareholder shall be obligated as set forth in Article
7 hereof.

     (c) DEATH OR DISABILITY. In the event that a Physician Shareholder dies or
         --------------------                                                 
becomes disabled, then the Physician Shareholder shall have no continuing
obligations under this Agreement; provided, however, in the event of disability,
the restrictive covenants described in Article 7 hereof shall remain in full
force and effect.

               ARTICLE 7. RESTRICTIVE COVENANTS AND ENFORCEMENT.
                          ------------------------------------- 

     MidSouth and the Practice recognize that the benefits each is to receive
under this Agreement shall be realized only if the Practice operates an active
medical practice to which the physicians associated with the Practice devote
their full time and attention to the extent of their arrangement with the
Practice. Accordingly, MidSouth and the Practice desire to set forth the
following reasonable restrictions and agreements regarding competition by the
physicians during the term of this Agreement and after the termination of this
Agreement.

                                       24
<PAGE>
 
     SECTION 7.1. EXCLUSIVE ARRANGEMENT. During the term of this Agreement,
                  ---------------------                                   
MidSouth shall be the Practice's and the Physician Shareholder' sole provider
of the management services described in this Agreement and neither the Practice,
the Physician Shareholder nor any of the Practice's or the Physician
Shareholder' employees shall provide similar management services. During the
term of this Agreement, the Practice and the Physician Shareholder agree that
neither the Practice nor Physician Shareholder will enter into any similar
agreement with any physician practice management company or entity.

     SECTION 7.2. RESTRICTIVE COVENANTS BY THE PRACTICE. The Practice agrees
                  -------------------------------------
that, during the term hereof, neither the Practice nor its Physician Shareholder
will engage, directly or indirectly, as a principal owner, shareholder (other
than a holder of fewer than 5% of the outstanding shares of a publicly-traded
company), partner, joint venturer, employee, agent, equity owner, or in any
other capacity whatsoever, in any corporation, partnership, joint venture, or
other business association or entity that operates ambulatory surgery or
diagnostic centers, imaging centers, physical therapy centers, or rehabilitation
centers, or provides management services of the nature provided by MidSouth
pursuant to this Agreement, within a thirty (30) mile radius from any of the
Practice Facilities (the "Restricted Area"). Provided that this Agreement may
allow any Physician Shareholder to own any ownership interest in the above
facilities which was acquired prior to the execution of this Agreement. If this
Agreement is terminated by MidSouth for breach by the Practice, pursuant to 
l0.4 hereof, neither the Practice nor its current or future Physician
Shareholders shall establish, operate, or provide physician services at any
medical office, clinic, ambulatory surgery or diagnostic centers, imaging
centers, physical therapy centers, rehabilitation centers or other health care
facility providing services substantially similar to those provided by the
Practice within the Restricted Area for a period of twenty-four (24) months
("Restricted Period") after the termination of the Agreement.

     SECTION 7.3. RESTRICTIVE COVENANTS BY CURRENT PHYSICIAN SHAREHOLDER.
                  ------------------------------------------------------
Physician Shareholder agrees that during the term of his employment and for the
Restricted Period after any termination of employment with the Practice, he will
not (i) establish, operate or engage, directly or indirectly, as a principal
owner, shareholder (other than a holder of fewer than 5% of the outstanding
shares of a publicly-traded company), partner, joint venturer, employee, agent,
equity owner, or in any other capacity whatsoever, in any corporation,
partnership, joint venture, or other business association or entity that
operates ambulatory surgery or diagnostic centers, imaging centers, physical
therapy, or rehabilitation centers providing services similar to those provided
by the Practice within the Restricted Area; or (ii) solicit, induce or attempt
to induce any Practice patient, employee, consultant or other persons associated
or affiliated with MidSouth or any Affiliate of MidSouth to leave the care of a
Physician Employee, to leave the employment of, or to discontinue their
association with the Practice, MidSouth or such affiliate of the Practice or
MidSouth within the Restricted Area. Provided that the employment agreements may
exclude from the restrictive covenant the employment of Physician Shareholder in
facilities that have historically been deemed emergency room facilities once the
Physician Shareholder's employment has been terminated if the Physician
Shareholder has no private practice. The Practice agrees to enforce the
restrictive covenants. The cost and expense of such enforcement shall be a
Practice Expense, and all damages and other amounts recovered thereby shall be
considered Practice Revenue. In the event that after

                                       25
<PAGE>
 
a request by MidSouth, the Practice does not pursue any remedy that may be
available to it by reason of a breach or Default of a restrictive covenant, upon
the request of MidSouth, the Practice shall assign to MidSouth such causes of
action and/or other rights it has related to such breach or Default and shall
cooperate with and provide reasonable assistance to MidSouth with respect
thereto; in which case, all costs and expenses incurred in connection therewith
shall be MidSouth Expenses, and MidSouth shall be entitled to all damages and
other amounts recovered thereby. If the Practice and/or Physician Shareholder
violate the covenants set forth in this Section 7.3, then the duration of the
restrictions contained in this Section 7.3 shall be extended an additional month
against the violator for each month during which such violation occurred but was
not discovered by MidSouth, beginning upon the date that MidSouth learns of the
violation and so notifies the Practice and/or the Physician Shareholder in
writing.

     SECTION 7.4. RESTRICTIVE COVENANTS BY FUTURE PHYSICIAN SHAREHOLDERS. The
                  ------------------------------------------------------     
Practice shall obtain and enforce formal agreements from each of its future
Physician Shareholders hired or contracted, pursuant to which each agrees to be
bound by an agreement containing the terms and conditions as contained in
Section 7.3 hereof. The agreements shall provide that MidSouth is an intended
third-party beneficiary to such agreements and that such third-party beneficiary
rights may be assigned to any Lender.

     SECTION 7.5. PHYSICIAN SHAREHOLDERS LIQUIDATED DAMAGES. The restrictive
                  -----------------------------------------
covenants described above may provide that any Physician Shareholders (current
or future) may be released from his or her Restrictive Covenants by paying
liquidated damages in an amount as follows:

     (a) if the Practice were the breaching party or the party desiring to be
released from the covenant, the Practice shall be liable to MidSouth for an
amount equal to the estimated fee payable to MidSouth hereunder for one hundred
twenty (120) months following the termination; and

     (b) if a Physician Shareholder was the breaching party or the party
desiring to be released from the covenant, then $200,000.00 per breaching party
or party desiring to be released from the covenant must be paid to MidSouth in
order to obtain Physician Shareholder's release from Article 7 of this
Agreement.

     SECTION 7.6. RIGHTS OF MIDSOUTH. During the term of this Agreement and
                  ------------------
thereafter, MidSouth shall at all times of this Agreement have the right to
enter into additional service agreements with other physicians and practices,
regardless of where such physicians and/or practices are located, providing for
management services and facilities to such physicians and/or practices.

     SECTION 7.7. EXCLUDED ACTIVITIES. Physician Employees shall be allowed to
                  -------------------
participate in Excluded Activities and retain Excluded Revenues, at any time so
long as the Excluded Activities do not interfere with any rights,
responsibilities or obligations as contained in this Agreement or any employment
agreement by and between the Practice and the Physician Employee. 

                                       26
<PAGE>
 
     SECTION 7.8. ENFORCEMENT. MidSouth, the Practice and the Physician
                  -----------
Shareholder acknowledge and agree that since a remedy under Applicable Law for
any breach or attempted breach of the provisions of this Article 7 shall be
inadequate, MidSouth shall be entitled to specific performance and injunctive or
other equitable relief in the event of any breach or attempted breach, in
addition to whatever other remedies may exist under Applicable Law or in equity.
All parties hereto also waive any requirement for the securing or posting of any
bond in connection with the obtaining of any injunctive or other equitable
relief. If any provision of Article 7 relating to any applicable Restrictive
Period, scope of activity restricted or the Restricted Area described therein
shall be declared by a court of competent jurisdiction to exceed the maximum
time period, scope of activity restricted or geographical area the court deems
reasonable and enforceable under Applicable Law, the time period, scope of
activity restricted and/or area of restriction held reasonable and enforceable
by the court shall thereafter be the Restrictive Period, scope of activity
restricted and/or the Restricted Area applicable to the restrictive covenant
provisions in this Article 7. The invalidity or non-enforceability of this
Article 7 in any respect shall not affect the validity or enforceability of the
remainder of this Article 7 or of any other provisions of this Agreement.

shall any excess be deemed a Practice Expense. MidSouth shall have the option,
with Management Team approval, of providing the professional liability insurance
through an alternative program, provided the program meets the requirements of
the Insurance Commissioner of the State. If the Practice's existing professional
liability insurance program is canceled and replaced by a professional liability
insurance program initiated by MidSouth, MidSouth shall pay over to the Practice
any unearned professional liability insurance premiums paid by the Practice to
the extent the Practice's carrier pays the amounts to MidSouth. Any insurance
program for the Practice shall include director and officer liability insurance
for the Practice, and the cost of the coverages shall be a Practice Expense.

employment agreement with Practice for a term of not less than three (3) years,
or will purchase equivalent insurance coverage. The provisions may be contained
in employment agreements, restrictive covenant agreements or other agreements
entered into by the Practice and the Physician Employees, and the Practice
hereby covenants with MidSouth to enforce the provisions relating to 

                                       29

the continuing or tail insurance coverage or to provide the coverage, which will
be a Practice Expense.

     9.3.2. The Practice shall obtain continuing liability insurance under
either a tail policy or an acts policy with the same limits and deductibles as
the comprehensive professional liability insurance at the time of the

            ------------------------------
a claim for indemnification under either the Merger Agreement or this Agreement
(the "Indemnified Party"), then the party who must provide indemnity (the
"Indemnifying Party"), shall have the right, to the extent it owes
indemnifications, to pay amounts owed to the Indemnified Party under the Merger
Agreement or this Agreement into an escrow account (established pursuant to an
escrow agreement to be agreed upon by the parties) to be held by the escrow
agent in an interest bearing account until a determination by either (i) the
parties, (ii) a court of proper jurisdiction or (iii) an agreed upon panel of
arbitrators, has been made regarding the Indemnified Party's right to
indemnification. In the event that the Indemnified Party is entitled to
indemnification, then such escrowed funds shall be paid to the Indemnified Party
in partial or complete satisfaction of such indemnification obligation. Any
excess funds remaining in the escrow account after the payment of the
indemnification obligation or any funds held in escrow account if it is
determined that no indemnification obligation is owed shall be paid to the
Indemnifying Party.

                                       32
<PAGE>
 
     (a) If this Agreement is terminated by MidSouth pursuant to Section 10.4 or
upon the expiration of the Term of this Agreement, purchase from MidSouth at
book value all intangible assets acquired in the Merger, as adjusted through the
last day of the month most recently ended prior to the date of the termination
or expiration to reflect amortization or depreciation of the "service agreement

    SECTION 10.6. CLOSING OF REPURCHASE BY THE PRACTICE AND EFFECTIVE DATE OF
                  -----------------------------------------------------------
TERMINATION. Except as provided in this Section 10.6, the Practice shall pay
- ------------
cash to repurchase the practice assets as provided in Section 10.5 (the
"Repurchase Price"). The Repurchase Price shall be reduced by the amount of debt
and liabilities of MidSouth assumed by the Practice and shall also be reduced by
any payment MidSouth has failed to make under this Agreement. The Practice and
any physician associated with the Practice shall execute all documents as may be
required to assume the liabilities set forth in Section 10.5, to remove MidSouth
from any liability with respect to the repurchased assets and with respect to
any property leased or subleased by MidSouth, and to consummate the transactions
contemplated by Section 10.5. The closing date for the purchase shall be
determined by the Practice, but shall in no event occur later than ninety (90)
days from the date of the notice of termination. The termination or expiration
of this Agreement shall become effective upon the closing of the sale of the
assets. On the date of termination or expiration, but only in the event the
termination or expiration of the Agreement was the result of the expiration of
the Term of this Agreement or a termination pursuant to Section 10.3, the
Practice shall be released from the restrictive covenants provided from in
Article 7. From and after any termination or expiration, each party shall
provide the other party with reasonable access to books and records then owned
by it to permit the requesting party to satisfy reporting and contractual
obligations which may be required of it. Except as otherwise provided herein,
the restrictive covenants contained in Article 7 shall survive the expiration or
earlier termination of this Agreement. MidSouth shall give the Practice   

                                       33
<PAGE>
 
credit toward the Repurchase Price for the fair market value of any of
MidSouth's Common Stock or the stock of any successor (whose stock is exchanged
for MidSouth Common Stock) tendered to MidSouth in exchange for such assets. As
used in this Section 10.6, the term "fair market value" with respect to a single
share of MidSouth Common Stock shall mean; (i) in the event this Agreement is
terminated for any reason prior to an initial public offering of MidSouth's
Common Stock or MidSouth's merger into a publicly traded company, five dollars
($5.00) per share (as adjusted by any conversion ratio applicable in a merger of
MidSouth into a non-public company); (ii) in the event MidSouth terminates this
Agreement pursuant to the terms of Section 10.4 subsequent to an initial public
offering of MidSouth's Common Stock or MidSouth's merger into a publicly traded
company, five dollars per share ($5.00) (as adjusted by any conversion ratio
applicable in a merger of MidSouth into a non-public company); or (iii) in the
event the Practice terminates this Agreement pursuant to the terms of Section
10.3 or the Term of this Agreement expires subsequent to an initial public
offering of MidSouth's Common Stock or MidSouth's merger into a publicly traded
company, the closing "asking price" for a single share of MidSouth's Common
Stock as of the date on which the repurchase is consummated, as reported on a
securities exchange or quoted on a national quotation system upon which the
MidSouth Common Stock is traded or quoted.

                ARTICLE 11. INTELLECTUAL PROPERTY AND RECORDS.
                            ----------------------------------

     SECTION 11.1. PROPRIETARY INFORMATION.  The Practice acknowledges that
                   ------------------------                              
MidSouth possess significant proprietary and confidential know-how, technology
and business information, including but not limited to, utilization protocols,
practice guidelines and proprietary management software and data ("Proprietary
Information"), which MidSouth has developed and will continue to develop on its
own, in its relationship with vendors, practitioner groups, integrated delivery
systems and other providers. The Practice and MidSouth acknowledge that one of
their mutual objectives is the development of Proprietary Information to be used
in connection with MidSouth's operations or which MidSouth intends to use or
license in its relationship with third parties, including other medical groups,
integrated delivery systems and other providers. In addition, the Practice
acknowledges that as of the Closing Date, by virtue of execution and delivery of
the Merger Agreement, MidSouth will have acquired all of the Practice's existing
Proprietary Information, excluding patient medical records. Therefore, the
parties agree that MidSouth shall own all new Proprietary Information, as well
as existing Proprietary Information, excluding patient medical records,
regardless of whether the new Proprietary Information is developed by one or
more physicians in the Practice or Affiliates. The Practice agrees to execute
and deliver such documentation as may be requested by MidSouth from time to time
to evidence such ownership. During the term of this Agreement, MidSouth shall
license and provide access to all existing Proprietary Information to the
Practice.

     SECTION 11.2. OWNERSHIP OF MIDSOUTH'S BUSINESS RECORDS AND SYSTEMS. All
                   ----------------------------------------------------
business records, information, software and systems of MidSouth relating to the
provision of its services under this Agreement shall remain the property of
MidSouth and may be removed by MidSouth upon any termination of this Agreement;
provided, however, that the Practice shall be entitled, upon reasonable written
request, to access such records and make copies or extracts thereof to the
extent 

                                       34
<PAGE>
 
necessary to prosecute or defend against any tax or other liabilities
imposed on the Practice by any Governmental Authority or other party.

     SECTION 11.3. MAINTENANCE AND ACCESS OF RECORDS. Except as otherwise
                   ----------------------------------                   
provided in this Agreement, the parties shall safeguard all records maintained
by them pursuant to this Agreement for a period of time specified by the
Management Team from the date of the last activity recorded in such records. In
particular, the parties agree, to the extent necessary to permit receipt of
reimbursement for services by the Practice, to make available to the Secretary
of the United States Department of Health and Human Services, the Comptroller
General, the General Accounting Office, or their authorized representatives or
analogous state officials, any books, documents and records in their possession
relating to the nature and extent of the costs of services hereunder for a
period of five (5) years after the provision of such services. Each party
further agrees that, if it contracts with any third party to provide services
that are valued in excess of $10,000, it shall require the contracting party to
comply with the requirements of the previous sentence. During the term of this
Agreement, and thereafter, the Practice or its designee shall have reasonable
access during normal business hours to the Practice's and MidSouth's financial
and accounting, including, but not limited to, records of collections, expenses
and disbursements as kept by MidSouth in performing MidSouth's obligations under
this Agreement, and the Practice may copy any or all records at its expense.
Nothing in this Section 11.3 constitutes the waiver of any attorney-client
privilege, and neither party shall be required hereunder to give the other party
documents if, as a result, an existing attorney-client privilege would be
waived.

     SECTION 11.4. PATIENT RECORDS. Upon termination of this Agreement, the
                   -----------------                                       
Practice shall retain all patient medical records maintained by the Practice or
MidSouth in the name of the Practice.

     SECTION 11.5. ACCESS TO RECORDS. During the term of this Agreement, and
                   -------------------                                      
thereafter, the Practice or its designee shall have reasonable access during
normal business hours to the Practice's and MidSouth's financial records,
including, but not limited to, records of collections, expenses and
disbursements as kept by MidSouth in performing MidSouth's obligations under
this Agreement, and the Practice may copy any or all records at its expense.

terms. The Practice and each Physician Shareholder have obtained all third-party
consents necessary to enter into and consummate the transaction contemplated by
this Agreement. Neither the execution and delivery of this Agreement, the
consummation of the transactions contemplated hereby, nor compliance by the
Practice or any Physician Shareholder with any of the provisions hereof, will:

certifications and contracts required for participation in such programs are in
full force and effect and have not been amended or otherwise modified, 
rescinded, revoked or assigned as of the date hereof, and no condition exists or
to the knowledge of the Practice no event has occurred which in itself or with
the giving of notice or the lapse of time or both would result in the

of all the Third Party Payor Programs applicable thereto.

     SECTION 12.7. FRAUD AND ABUSE. The Practice, the Practice Employees and

other persons and entities providing professional services for the Practice have
not, to the knowledge of the Practice and each Physician Shareholder, after due
inquiry, engaged in any activities which are prohibited by or are in violation

Price with respect to the Purchased Accounts Receivable and with respect to
Governmental Receivables, to the extent permissible by Applicable Law, all
right, title and interest of the Practice with respect thereto shall be vested
in MidSouth, free and clear of any lien, security interest, claim or encumbrance
of any kind, and the Practice agrees to defend the same against the claims of
all persons.

Practice and MidSouth, any purchase of Purchased Accounts Receivable is not
characterized as a sale, the Practice shall, effective as of the date hereof, be
deemed to have granted and the Practice does hereby grant to MidSouth a first
priority security interest in and to any and all of the Purchased Accounts
Receivable and the proceeds thereafter secure the repayment of all amounts

                          ARTICLE 15. MISCELLANEOUS.
                                      -------------

     SECTION 15.1. ASSIGNMENT. MidSouth shall have the right to assign without
                   ----------
the consent of the Practice all of its rights hereunder to any person, firm or
corporation (i) under common control with MidSouth, (ii) to any lending
institution, for security purposes or as collateral, from which MidSouth obtains
financing, or (iii) that is an affiliate of MidSouth, including, but not limited
to, a parent, subsidiary, or brother-sister corporation, and MidSouth shall have
the right to assign with the consent of the Practice (which shall not be
unreasonably withheld) all rights hereunder to any firm, person or corporation
that merges, reorganizes, or otherwise consolidates with MidSouth and further
agrees that upon receipt of notice from such assignee, the Practice shall pay to
the assignee or cause to be paid to the assignee all amounts due and payable to
MidSouth pursuant to this Agreement. Without limiting the foregoing, the
Practice acknowledges that, as collateral for certain obligations, MidSouth has
assigned all of its rights hereunder to a Lender as agent (the "Agent") for
itself and other banks and institutional lenders from time to time (collectively
the "Banks") and has granted the Agent for the benefit of the Banks a lien and
security interest upon all real and personal property owned by MidSouth
("Pledged Assets"). As an inducement for the Banks to extend or continue the
extension of credit to MidSouth, the Practice (i) acknowledges that the
collateral assignment to the Agent covers all rights of MidSouth hereunder,
including, but not limited to, rights arising from warranties and
representations made by the Practice, rights to enforce covenants made by the
Practice, and rights to receive all payments due MidSouth; (ii) agrees to regard
the Agent as the owner of any and all of the assigned rights upon written notice
to the Practice of this election from the Agent; (iii) agrees that neither the
Agent nor any of the Banks has obligation for the performance of the duties of
MidSouth hereunder, and shall not assume any such duty by the exercise of rights
as a secured lender; (iv) agrees to give the Agent written notice of any
Material Default hereunder on MidSouth's part at the address provided in writing
to Practice by the Agent and to allow cure periods as provided in Section 10.3
thereafter for the cure of Default before the Practice terminates this
Agreement; (v) agrees that the rights of the Practice under this Agreement,
including, but not limited to, the right to the use of the Pledged Assets, are
and shall be junior to any security interest that the Agent and the Banks, their
successors or assigns may have in the Pledged Assets at any time; (vi) agrees
that the benefits of the above undertakings in favor of the Agent and Banks
shall further extend to all successors and assigns of the Agent and Banks,
provided that any notices given by the Practice under this Section 15.1 shall be
given to the Agent at the foregoing address unless the Practice has received
written notice of a change thereof; and (vii) agrees that this Section 15.1 may
not be modified, and no provision of this Section 15.1 may be waived, absent the
written approval 

                                       43
<PAGE>
 
of the Agent and Banks. Further, if a majority of the shareholders of MidSouth
entitled to vote on a sale of all of the assets or substantially all of the
assets or common stock of MidSouth authorize the sale or transfer of all or
substantially all of the assets or common stock of MidSouth to a third party
(the "Acquiring Party"), this Agreement shall be deemed automatically assigned
and transferred to the Acquiring Party without the necessity of obtaining the
consent of the Practice. Except as set forth above, neither MidSouth nor the
Practice shall have the right to assign their respective rights and obligations
hereunder without the written consent of the other party.

     SECTION 15.2. THIS AGREEMENT. This Agreement sets forth the entire
                   --------------

negotiations and all contemporaneous oral agreements concerning the subject
matter. There are no oral conditions precedent to the effectiveness of this
Agreement.

     SECTION 15.3. NO PRACTICE OF MEDICINE. The parties acknowledge that
                   -----------------------                              
MidSouth is not authorized or qualified to engage in any activity which may be
construed or deemed to constitute the practice of medicine. To the extent any
act or service required of MidSouth in this Agreement should be construed or
deemed by any Governmental Authority or court to constitute the practice of
medicine, the performance of said act or service by MidSouth shall be deemed
waived and unenforceable to the minimum extent required to comply with
Applicable Law.

     SECTION 15.4. NON-WAIVER. Neither the failure of nor any delay by any party
                   ----------                                                   
to this Agreement to enforce any right hereunder or to demand compliance with
its terms is a waiver of any right hereunder. No action or inaction taken
pursuant to this Agreement on one or more occasions is a waiver of any right
hereunder or constitutes a course of dealing that modifies this Agreement.

     SECTION 15.5. WAIVERS. No waiver of any right or remedy under this
                   -------
Agreement shall be binding on any party, unless it is in writing and is signed
by the party to be charged. No waiver of any right or remedy under any term of
this Agreement shall in any event be deemed to apply to any subsequent Default
under the same of any other term contained herein.

     SECTION 15.6. AMENDMENTS. No amendment, modification or termination of this
                   ----------
Agreement shall be binding on any party hereto unless it is in writing and is
signed by the party to be charged.

     SECTION 15.7. SEVERABILITY. The terms of this Agreement are severable and
                   ------------
the invalidity of all or any part of any term of this Agreement shall not render
invalid the remainder of this Agreement or the remainder of the term. If any
term of this Agreement is so broad as to be unenforceable, the term shall be
interpreted to be only so broad as is enforceable.

     SECTION 15.8. SUCCESSORS. The terms of this Agreement shall be binding upon
                   ----------
and inure to the benefit of the parties, their respective successors, assigns,
heirs and beneficiaries.

     SECTION 15.9. THIRD PARTIES. Nothing herein expressed or implied is
                   -------------
intended or shall be construed to give any person other than the parties hereto
any rights or remedies under this Agreement.

into by and among Physician Health Corporation, a Delaware corporation ("PHC"),
PHC St Louis Acquisition Subsidiary I, Inc., a Georgia corporation
("Subsidiary"), Metropolitan Plastic and Reconstructive Surgery, Ltd., a
Missouri corporation ("MPRS") and J. Michael Ribaudo, M.D.,an individual
resident of the State of Missouri ("Ribaudo").

     PHC and the Subsidiary are hereinafter collectively referred to as PHC
entities.  MPRS and Ribaudo are hereinafter collectively referred to as the
Ribaudo entities.

     WHEREAS, Ribaudo is sole shareholder of MPRS;

     WHEREAS, the parties to this Agreement, simultaneously with execution of
this Agreement have entered into that certain Asset Purchase Agreement
("Purchase Agreement") pursuant to which MPRS shall become a subsidiary of PHC
and certain additional agreements with respect to the provision of services by
and among the parties hereto have been entered into by including but not limited
to that certain Practice Management Agreement, of even date herewith, and other
documents;

     NOW, THEREFORE, in consideration of the mutual promises and covenants set
out in the Purchase Agreement, and the Agreements delivered pursuant to it, One
Dollar ($1.00), and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged by the parties hereto, the parties
agree as follows:

     1. Ribaudo: ISO Shares At Closing.  PHC agrees that upon closing it shall
        ------------------------------                                        
grant to Ribaudo stock options to purchase 300,000 shares of PHC common stock
which options shall vest over four (4) years and which options shall be issued
in accordance with the terms and conditions of the PHC Incentive Stock Option
Plan; provided that such vesting shall be accelerated to 100% vesting at such
time as PHC completes a single sale of securities resulting in a change in
control in PHC.  The strike price of such options shall be $4.00 per share.

     2. Ribaudo: ISO Shares Upon Meeting Earnings Target.  PHC agrees to grant
        ------------------------------------------------                       
Ribaudo stock options immediately to purchase 150,000 shares of PHC common
stock, which shall begin to vest (the "Vesting Start Date") upon achievement of
$1.5 Million in projected annual practice management revenue from the Missouri
and central and southern Illinois markets by PHC for the period commencing on
the date hereof and ending on June 1, 1997.  Such stock options shall be issued
in accordance with the terms and conditions of the PHC Stock Option Plan.  Of
such options, 25,000 vest on the Vesting Start Date, and 31,250 shall vest on
each of the next four anniversaries of the Vesting Start Date; provided, that if
the Vesting Start Date conditions are met, all such stock options shall fully
vest at such time as PHC completes an initial public offering of its stock or
upon a single sale of securities resulting in a change in control of PHC.  The
strike price for such options shall be $4.00 per share.  Should Ribaudo not
exercise such options until immediately 
<PAGE>
 
prior to the initial public offering or a change in control of PHC, PHC will pay
Ribaudo $600,000 at such time (and Ribaudo shall retain the right to also
exercise such options).

     3. Ribaudo: Additional Stock Purchase At Closing.  At closing, PHC agrees
        ---------------------------------------------                         
to sell and Ribaudo agrees to purchase an additional 100,000 shares of PHC
common stock at a purchase price of $4.00 per share for an aggregate purchase
price of $400,000.00 paid in cash.  Such purchase and sale shall be achieved in
compliance with and subject to obtaining appropriate state and federal
securities laws exemptions, along with all other stock transactions contemplated
in the Purchase Agreement and this Agreement.

     4. Ribaudo: Standard Compensation.  PHC agrees to employ Ribaudo, on an at-
        ------------------------------                                         
will basis, with standard compensation from the date of Closing of the Asset
Purchase Agreement and calculated at an annual rate of $100,000.00.  Such amount
shall be adjusted from time to time as deemed appropriate by the Board of
Directors of PHC.  In addition, PHC agrees that if Ribaudo continues to be
employed by the Company after the completion of an initial public offering of
the shares of PHC, then Ribaudo's compensation shall be increased to an annual
rate of $250,000.00.

     5. Ribaudo: Additional Compensation.  PHC agrees to provide Ribaudo with a
        --------------------------------                                       
quarterly draw in the amount of $87,500, to be paid in monthly installments, one
month in arrears, commencing with the closing of Subsidiary's purchase of MPRS's
assets, until PHC has completed an initial public offering of its common stock
("Quarterly Draw").  At the end of each applicable quarter, the then-outstanding
Quarterly Draw shall be compared with new earnings from new physician practices
acquired by PHC (other than Ribaudo's practice) for which Ribaudo had a
substantial role (as determined in good faith by PHC) so that Ribaudo receives
credit as specified below for the specified percent of the annualized earnings
amounts used by PHC in determining the purchase price for such new practices
acquired in such quarter, provided that Ribaudo's Earned Quarterly Draw shall
not exceed $87,500:

     a. (2.5%) (Annualized new practice management earnings acquired from
        practices in transactions during the applicable quarter for which
        Ribaudo was the procuring party for the transaction), plus

     b. For the first 12-month period only, (0.5%) (Annualized new practice
        management earnings acquired from practices in transactions during the
        applicable quarter for which Ribaudo had a substantial role but was not
        the procuring party for the transaction) = Earned Quarterly Draw.

Should the Earned Quarterly Draw, calculated according to the formula set out
above, be less than the Quarterly Draw actually received by Ribaudo, PHC shall
offset such deficiency first against all 
<PAGE>
 
payments owed to Ribaudo by PHC under that certain $500,000 promissory note
issued by PHC to Ribaudo in connection with the sale of his practice to PHC, and
second, against all other amounts owed or due to Ribaudo from PHC until such
deficit is satisfied. Once the actual Quarterly Draw received by Ribaudo for
such quarter has been offset to the extent provided above, Ribaudo shall receive
an Earned Quarterly Draw for the next quarter in the same amount of $87,500 and
subject to the same quarterly reconciliation. Notwithstanding anything to the
contrary, the Earned Quarterly Draw can only he drawn upon by Ribaudo in each
month to the extent necessary to allow Ribaudo to receive, together with all
revenue received by Ribaudo from his medical practice, $29,166.66. Upon any
public offering of PHC common stock, Ribaudo's additional compensation hereunder
shall cease, and Ribaudo's Earned Quarterly Draw for any partial quarter up to
that date shall be determined and compared with the actual Earned Quarterly Draw
taken during such partial quarter by Ribaudo and any deficiency in the amount of
the Earned Quarterly Draw may be offset by PHC against any amounts owed or due
to Ribaudo from PHC.

     6. Ribaudo: Board Seat.  PHC agrees that shortly after closing it
        -------------------                                           
shall cause Ribaudo to be named as a member of the Board of Directors of PHC.
Ribaudo shall serve in such capacity in accordance with the Articles of
Incorporation and Bylaws of PHC.

     7. Ribaudo:  Profit Representation.  Ribaudo hereby represents and
        -------------------------------                                
covenants to PHC that MPRS shall have a profit for the twelve (12) month period
commencing with the closing of Subsidiary's purchase of MPRS's assets, before
payment of the Practice Management Fee otherwise agreed between the parties, in
excess of $100,000.00.  To the extent that such profit is not achieved, PHC may
offset any deficiency against any payment or other compensation owed or due to
Ribaudo by PHC.

     8. [Reserved.]

     9. MPRS:  Adjustment for Tax Effect.  PHC shall loan MPRS such funds
        --------------------------------                                 
as necessary to manage the taxable effect incurred in connection with the
Purchase Agreement (as compared to a merger transaction) taking into account the
time value of money and the increase in basis of MPRS as calculated by Arthur
Andersen or other accountants suitable to the parties ("Tax Loan").  Such Tax
Loan shall be secured by common stock received in connection with the Purchase
Agreement, paid at the time of any public offering of PHC stock.

    10. Block:  ISO Shares.  Provided that Peggy Block becomes a full-
        ------------------                                           
time employee of PHC, PHC agrees to grant Peggy Block stock options to purchase
75,000 shares of PHC common stock, which shall begin to vest (the "Vesting Start
Date") upon achievement of $1.5 Million in projected annual practice management
revenue from the Missouri and central and southern Illinois markets by PHC for
the period commencing on the date hereof and ending on June 1, 1997.  Such stock
options shall be issued in accordance with the terms and conditions of the PHC
Stock Option Plan.  Of such options, 12,500 shall vest on the Vesting Start
Date, and 15,625 shall vest on each of the next four anniversaries of the
Vesting Start Date; provided, that if the Vesting Start Date 
<PAGE>
 
conditions are met, all such stock options shall fully vest at such time as PHC
completes an initial public offering of its stock or upon a single sale of
securities resulting in a change in control of PHC. The strike price for such
options shall be $4.00 per share. Peggy Block shall be permitted to work, on her
own time, not more than five (5) hours per month in supervising the financial
aspects of the personal business interest of Ribaudo and MPRS without being
considered other than a full-time employee of PHC.

    11. Block:  Additional Performance Shares.  Provided that Peggy Block
        -------------------------------------                            
becomes a full-time employee of PHC, PHC agrees to grant Peggy Block an
additional 25,000 shares under its Incentive Stock Option Plan provided that PHC
achieves $1.5 million of projected annual practice management revenue from the
Missouri-central and southern Illinois markets in the twelve (12) month period
commencing with the Closing of Subsidiary's purchase of MPRS's assets, in
accordance with the terms and conditions of PHC Incentive Stock Option Plan.
The strike price for such shares shall be $4.00 per share.

    12. Block:  Title and Compensation.  PHC agrees to employ Peggy
        ------------------------------                             
Block, on an at-will basis, under title of "Vice President of Operations" or
similar title at Closing.  Such title shall be adjusted at the discretion of the
President and the Board of Directors of PHC from time to time.  PHC agrees to
provide her with standard compensation of $75,000 per year, payable in equal
monthly installments.

    13. "B" Stock.  MPRS agrees to negotiate with PHC prior to the
        ---------                                                 
closing of Subsidiary's purchase or MPRS's shares for the substitution of a "B"
common stock as the share consideration under the Purchase Agreement; provided
(i) such "B" common stock shall convert fully into "A" common stock as of the
earlier of the date of PHC's initial public offering or the date of PHC's
otherwise accessing the public securities market; and (ii) such "B" common stock
shall reduce the tax effects of the transactions contemplated in the Asset
Purchase Agreement and all related agreements, or otherwise provide a direct
benefit to both parties.

    14. The obligations of both parties under this Agreement shall not be
enforceable until this Agreement has been approved by the Board of Directors of
PHC.

    15. Ribaudo (for himself and on behalf of Peggy Block) and PHC agree that if
the Board of Directors of PHC, based upon the advice of legal counsel and/or
investment bankers engaged for the purpose of assisting in a public offering or
extraordinary private placement of PHC stock, determines in good faith that any
one or more terms of this Agreement will or could have a significant adverse
affect on PHC's ability to complete a registration of its shares or otherwise to
complete such proposed public offering or private placement in the manner and on
the terms proposed by such counsel or bankers, then Ribaudo and Block will
negotiate in good faith with PHC with the purpose of amending this Agreement and
any other applicable agreements entered into in connection herewith to the
extent necessary to eliminate such adverse affect, so long as any such
<PAGE>
 
amendments do not materially reduce the total economic benefits to Ribaudo and
Block provided under this Agreement.

     IN WITNESS WHEREOF, the parties hereto have affixed their signatures
effective as of the date first written above.

indemnified by the Investors and the Company from all losses, costs and expenses
that may be incurred by it as a result of its involvement in any arbitration or
litigation arising from the performance of its duties hereunder, provided that
such arbitration or litigation shall not result from any action taken or omitted
by the Escrow Agent for which it shall have been adjudged to have failed to
comply with the standards of conduct in Section 4.3. The Investors (on a joint
and several basis), on one hand, and the Company, on the other hand, shall each
be liable for one-half of any amount paid to the Escrow Agent as indemnification

of all Warrants). Such indemnification shall survive termination of this
Agreement until extinguished by any applicable statute of limitations.

  3.11. No Ownership Interest. The Escrow Agent does not have any interest in
        ---------------------
the Escrow Assets hereunder but is serving as escrow holder only and having only
possession thereof. This paragraph shall survive notwithstanding any termination

  3.12. Resignation. The Escrow Agent (and any successor Escrow Agent) may at
        -----------
any time resign by delivering the Investor Securities in the Securities Escrow
to any successor Escrow Agent jointly designated by the other parties hereto in
writing or to any court of competent jurisdiction, whereupon the Escrow Agent
shall be discharged from any further obligations arising in connection with this
Agreement. The resignation of the Escrow Agent will take effect on the earlier
of (a) the appointment of a successor (including an order by a court of
competent jurisdiction) or (b) the day that is 30 days after the date of
delivery of its written notice of resignation to the other parties hereto. If at
that time the Escrow Agent has not received a designation of a successor Escrow
Agent, the Escrow Agent's sole responsibility after that time shall be to
safekeep the Escrow Assets until receipt of a designation of successor Escrow
Agent, or a joint written instruction as to disposition of the Escrow Assets by
the other parties hereto, or a final order of a court of competent jurisdiction
mandating disposition of Escrow Assets. If no successor

                                      -4-
<PAGE>
 
escrow agent  is appointed at the end of such 30 day period, the Escrow Agent
may apply to a court of competent jurisdiction for such appointment.

  3.13. Acceptance of Duties: Payment of Costs. The Escrow Agent hereby accepts
        --------------------------------------
its appointment and agrees to act as escrow agent under the terms and conditions
of this Agreement and acknowledges receipt of the Investor Securities in respect

reasonable administrative charges, out-of-pocket expenses, disbursements and
advances incurred or made by the Escrow Agent in performance of its duties
hereunder (including reasonable fees, and out-of-pocket expenses and
disbursements, of its counsel), not to exceed $2,000, unless there is a dispute
between the parties arising from the Escrow Agent's performance of its duties or
this Agreement.

  3.14. No Offset. The Escrow Agent shall have no right to offset against any
        ---------                                                            
Escrow Assets for any debts, claims or other obligations owing to it by the
Company, the Investors or any other person. The Escrow Agent shall have no lien
against the Escrow Assets.

  3.15. General Action. The Escrow Agent may execute any of its powers or 
        --------------
responsibilities hereunder and exercise any rights hereunder either directly or
by or through its agents or attorneys. Nothing in this Agreement shall be deemed
to impose upon the Escrow Agent any duty to qualify to do business or to act as
fiduciary or otherwise in any jurisdiction other than The Commonwealth of
Massachusetts. The Escrow Agent shall not be responsible for and shall not be
under a duty to examine into or opine upon the validity, binding effect,
execution or sufficiency of this Agreement or of any agreement amendatory or
supplemental hereto.

          WHEREAS, the Borrower has requested that the Original Credit Agreement
be amended and restated and the Banks and the Agent are willing to amend and
restate the same upon the terms and conditions set forth below;

          NOW, THEREFORE, the parties hereto agree that the Original Credit

                      -------------------------- 

          1.01  The Commitments.  (a)  Subject to and upon the terms and
                ---------------

agrees to make, on the Initial Borrowing Date and on the DVI Payment Date (so
long as the DVI Payment Date occurs prior to the Term Loan Commitment
Termination Date), a term loan (each, a "Term Loan" and, collectively, the "Term
Loans") to the Borrower, which Term Loans (i) shall be Base Rate Loans or
Eurodollar Loans; provided that (x) except as otherwise specifically provided in
                  --------                                                      
Section 1.10(b), all Term Loans comprising the same Borrowing shall at all times
be of the same Type and (y) no Eurodollar Loans may be incurred prior to the
Syndication Termination Date and (ii) shall not exceed for any Bank, in initial
aggregate principal amount, that amount which equals the Term Loan Commitment of
such Bank on such date (before giving effect to any reductions thereto on such
date pursuant to Section 3.03(b)(i), 3.03(b)(iii) and 3.03(b)(v) but after
giving effect to any reductions thereto on
<PAGE>
 
or prior to such date pursuant to Section 3.03(b)(ii) and 3.03(b)(iv)) less such
Bank's Term Loan Commitment Percentage of the Blocked Commitment; provided,
                                                                  --------
however that Term Loans made after the Initial Borrowing Date shall be made from
- -------
the Blocked Commitment for each Bank and shall be in an amount equal to such
Bank's Term Loan Commitment Percentage of the Blocked Commitment. Once repaid,
Term Loans incurred hereunder may not be reborrowed. In addition, on the
Restatement Effective Date, the Borrower and Banque Paribas agree that $2
million of the Acquisition Loans which had been made pursuant to the Original
Credit Agreement prior to the Restatement Effective Date shall be deemed
automatically converted into an additional Borrowing of Term Loans.

          (b)  Subject to and upon the terms and conditions set forth herein,
each Bank with an Acquisition Loan Commitment severally agrees to make, at any
time and from time to time after the Acquisition Loan Commencement Date and
prior to the Acquisition Loan Termination Date, a loan or loans (each an
"Acquisition Loan" and, collectively, the "Acquisition Loans") to the Borrower,
which Acquisition Loans (i) shall, at the option of the Borrower, be Base Rate
Loans or Eurodollar Loans; provided that (x) except as otherwise specifically
                           --------                                          
provided in Section 1.10(b), all Acquisition Loans comprising the same Borrowing
shall at all times be of the same Type and (y) no Eurodollar Loans may be
incurred prior to the Syndication Termination Date and (ii) shall not exceed for
any Bank, in initial aggregate principal amount, that amount which equals the
Acquisition Loan Commitment of such Bank at such time (before giving effect to
any reductions thereto on such date pursuant to Section 3.03(c)(i) or Section
3.03(c)(ii) but after giving effect to any reductions thereto on or prior to
such date pursuant to Section 3.03(c)(iii)).  Once repaid, Acquisition Loans
incurred may not be reborrowed; provided, however that the $2 million of
                                --------  -------                       
Acquisition Loans converted to Term Loans or Revolving Loans in accordance with
the next succeeding sentence and any Acquisition Loans repaid in accordance with
Section 4.02(A)(e)(i) from the proceeds of the initial public offering of common
equity of Holdings shall be permitted to be reborrowed.  After giving effect to
the conversion of $2 million of the Acquisition Loans to Term Loans in
accordance with Section 1.01(a) on the Restatement Effective Date, Acquisition
Loans in an amount set forth on Part B of Schedule I shall be outstanding on the
Restatement Effective Date.  No Acquisition Loans may be incurred on the
Restatement Effective Date.

          (c)  Subject to and upon the terms and conditions set forth herein,
each Bank with a Revolving Loan Commitment severally agrees at any time and from
time to time after the Initial Borrowing Date and prior to the Revolving Loan
Maturity Date, to make a loan or loans (each a "Revolving Loan" and,
collectively, the "Revolving Loans") to the Borrower, which Revolving Loans (i)
shall, at the option of the Borrower, be Base Rate Loans or Eurodollar Loans;
provided that (x) except as otherwise specifically provided in Section 1.10(b),
- --------                                                                       
all Revolving Loans comprising the same Borrowing shall at all times be of the
same Type and (y) no Eurodollar Loans may be incurred prior to the Syndication
Termination Date, (ii) may be repaid and reborrowed in accordance with the
provisions hereof, (iii) shall not exceed for any Bank at any time outstanding
that aggregate principal 

                                      -2-
<PAGE>
 
amount which, when added to the product of (x) such Bank's Percentage and (y)
the sum of (I) the aggregate amount of all Letter of Credit Outstandings
(exclusive of Unpaid Drawings which are repaid with the proceeds of, and
simultaneously with the incurrence of, the respective incurrence of Revolving
Loans) and (II) the aggregate principal amount of all Swingline Loans then
outstanding (exclusive of Swingline Loans which are repaid with the proceeds of,
and simultaneously with the incurrence of, the respective incurrence of
Revolving Loans), equals the Revolving Loan Commitment of such Bank at such time
and (iv) shall not exceed for all Banks at any time that aggregate principal
amount which, when added to the aggregate principal amount of all Swingline
Loans then outstanding and the aggregate amount of all Letter of Credit
Outstandings at such time, equals the Borrowing Base at such time.

          (d)  Subject to and upon the terms and conditions herein set forth,
the Swingline Bank agrees to make at any time and from time to time after the
Initial Borrowing Date and prior to the Swingline Expiry Date, a loan or loans
to the Borrower (each a "Swingline Loan," and collectively, the "Swingline
Loans"), which Swingline Loans (i) shall be made and maintained as Base Rate
Loans; (ii) may be repaid and reborrowed in accordance with the provisions
hereof; (iii) shall not exceed in aggregate principal amount at any time
outstanding, when combined with the aggregate principal amount of (x) all
Revolving Loans then outstanding and (y) all Letter of Credit Outstandings at
such time (exclusive of Unpaid Drawings which are repaid with the proceeds of,
and simultaneously with the incurrence of, the respective incurrence of
Swingline Loans), an amount equal to the lesser of (A) the Total Revolving Loan
Commitment at such time (after giving effect to any reductions to the Total
Revolving Loan Commitment on such date) and (B) the Borrowing Base at such time;
and (iv) shall not exceed in aggregate principal amount at any time outstanding
the Maximum Swingline Amount.  The Swingline Bank shall not be obligated to make
any Swingline Loans at a time when a Bank Default exists unless the Swingline
Bank has entered into arrangements satisfactory to it and the Borrower to
eliminate the Swingline Bank's risk with respect to the Defaulting Bank's or
Banks' participation in such Swingline Loans, including by cash collateralizing
such Defaulting Bank's or Banks' Percentage of the outstanding Swingline Loans.
The Swingline Bank shall not make any Swingline Loan after receiving a written
notice from the Borrower or the Required Banks stating that a Default or an
Event of Default exists and is continuing until such time as the Swingline Bank
shall have received written notice of (i) rescission of all such notices from
the party or parties originally delivering such notice, (ii) the waiver of such
Default or Event of Default by the Required Banks, (iii) the Agent in good faith
believes that such Default or Event of Default has ceased to exist or (iv) the
consent of the Required Banks to make Swingline Loans notwithstanding the
existence of such Default or Event of Default.

          (e)  On any Business Day, the Swingline Bank may, in its sole
discretion, give notice to the Banks that its outstanding Swingline Loans shall
be funded with a 

                                      -3-
<PAGE>
 
Borrowing of Revolving Loans, provided that such notice shall be deemed to have
                              --------
been automatically given upon the occurrence of a Default or an Event of Default
under Section 10.05 or upon the exercise of any of the remedies provided in the
last paragraph of Section 10, in which case a Borrowing of Revolving Loans
constituting Base Rate Loans (each such Borrowing, a "Mandatory Borrowing")
shall be made on the immediately succeeding Business Day from all Banks with a
Revolving Loan Commitment (without giving effect to any terminations and/or
reductions thereto pursuant to the last paragraph of Section 10) pro rata on the
                                                                 --- ----
basis of their respective Percentages (determined before giving effect to any
termination of the Revolving Loan Commitments pursuant to the last paragraph of
Section 10) and the proceeds thereof shall be applied directly to the Swingline
Bank to repay the Swingline Bank for such outstanding Swingline Loans. Each such
Bank hereby irrevocably agrees to make Revolving Loans upon one Business Day's
notice pursuant to each Mandatory Borrowing in the amount and in the manner
specified in the preceding sentence and on the date specified in writing by the
Swingline Bank notwithstanding (i) the amount of the Mandatory Borrowing may not
comply with the minimum amount for Borrowings otherwise required hereunder, (ii)
whether any conditions specified in Section 6 are then satisfied, (iii) whether
a Default or an Event of Default then exists, (iv) the date of such Mandatory
Borrowing and (v) any reduction in the Total Revolving Loan Commitment after any
such Swingline Loans were made. In the event that any Mandatory Borrowing cannot
for any reason be made on the date otherwise required above (including, without
limitation, as a result of the commencement of a proceeding under the Bankruptcy
Code with respect to the Borrower), then each such Bank hereby agrees that it
shall forthwith purchase (as of the date the Mandatory Borrowing would otherwise
have occurred, but adjusted for any payments received from the Borrower on or
after such date and prior to such purchase) from the Swingline Bank (without
recourse or warranty) such participations in the outstanding Swingline Loans as
shall be necessary to cause such Banks to share in such Swingline Loans ratably
based upon their respective Percentages (determined before giving effect to any
termination of the Revolving Loan Commitments pursuant to the last para graph of
Section 10); provided that (x) all interest payable on the Swingline Loans shall
             --------
be for the account of the Swingline Bank until the date as of which the
respective participation is required to be purchased and, to the extent
attributable to the purchased participation, shall be payable to the participant
from and after such date and (y) at the time any purchase of participations
pursuant to this sentence is actually made, the purchasing Bank shall be
required to pay the Swingline Bank interest on the principal amount of
participation purchased for each day from and including the day upon which the
Mandatory Borrowing would otherwise have occurred to but excluding the date of
payment for such participation, at the rate otherwise applicable to Revolving
Loans maintained as Base Rate Loans here under for each day thereafter.

          (f)  (i) Each New Bank shall purchase by assignment and assumption
from Banque Paribas on the Restatement Effective Date (without recourse to,
representation or warranty by (other than as expressly provided in this Section
1.01(f)), Banque Paribas), 

                                      -4-
<PAGE>
 
outstanding Loans made by Banque Paribas to the Borrower pursuant to the
Original Credit Agreement, with each New Bank to purchase Loans in an aggregate
principal amount so that after giving effect to all such assignments the
outstanding principal amount of Loans of each Bank under each facility shall be
as set forth on Part B of Schedule I. Each of the Banks hereby further agree
that such assignments shall be effected on the Restatement Effective Date as a
result of the New Banks making to Agents for the account of Banque Paribas
payments in an amount equal to the total outstanding amount of Loans of such
Bank as set forth on Part B of Schedule I.

          (ii)  (x) on the Restatement Effective Date all accrued (but
theretofore unpaid) interest with respect to all outstanding Loans under the
Original Credit Agreement immediately prior to the Restatement Effective Date
shall be paid by the Borrower and (y) all Fees under, and as defined in, the
Original Credit Agreement (including, without limitation, Commitment Commissions
(as defined in the Original Credit Agreement)) accrued prior to the Restatement
Effective Date shall be paid on the Restatement Effective Date by the Borrower.

          (iii) Banque Paribas hereby represents and warrants to each New Bank
purchasing Loans from Banque Paribas by way of assignment pursuant to this
Section that it is the legal and beneficial owner of such Loans being assigned
by it under this Section to such New Bank and that such Loans are free and clear
of any adverse claim with respect to its legal and beneficial ownership thereof.

          1.02  Minimum Amount of Each Borrowing.  The aggregate principal
                --------------------------------                          
amount of each Borrowing under a Facility hereunder shall not be less than the
Minimum Borrowing Amount for such Facility and, if greater, shall be in integral
multiples of $100,000 in the case of all Loans (other than Swingline Loans) and
$50,000 in the case of Swingline Loans.  More than one Borrowing may occur on
the same date, but at no time shall there be outstanding more than five
Borrowings of Eurodollar Loans.

          1.03  Notice of Borrowing.  (a)  Whenever the Borrower desires to make
                -------------------                                             
a Borrowing hereunder (excluding Borrowings of Swingline Loans and Mandatory
Borrowings), it shall give the Agent at its Notice Office, prior to 11:00 A.M.
(New York time) at least one Business Day's prior written notice (or telephonic
notice promptly confirmed in writing) of each Borrowing of Base Rate Loans and
at least three Business Days' prior written notice (or telephonic notice
promptly confirmed in writing) of each Borrowing of Eurodollar Loans. Each such
notice (each a "Notice of Borrowing"), except as otherwise expressly provided in
Section 1.10, shall be irrevocable and shall be given by the Borrower in the
form of Exhibit A-1, appropriately completed to specify (i) the aggregate
principal amount of the Loans to be made pursuant to such Borrowing, (ii) the
date of such Borrow ing (which shall be a Business Day), (iii) whether the Loans
being made pursuant to such Borrowing shall constitute Term Loans, Revolving
Loans or Acquisition Loans and (iv)

                                      -5-
<PAGE>
 
whether the Loans being made pursuant to such Borrowing are to be initially
maintained as Base Rate Loans or Eurodollar Loans and, if Eurodollar Loans, the
initial Interest Period to be applicable thereto. Any notice received after
11:00 A.M. (New York time) shall be deemed to be received on the next succeeding
Business Day. The Agent shall promptly give each Bank which is required to make
Loans of the Tranche specified in the respective Notice of Borrowing notice of
such proposed Borrowing, of such Bank's proportionate share thereof and of the
other matters specified in the Notice of Borrowing.

          (b)  (i)  Whenever the Borrower desires to make a Borrowing of
Swingline Loans hereunder, it shall give the Swingline Bank not later than 11:00
A.M. (New York time) on the date that the Swingline Loan is to be made, written
notice (or telephonic notice confirmed in writing) of each Swingline Loan to be
made hereunder.  Each such notice shall be irrevocable and specify in each case
(A) the date of Borrowing (which shall be a Business Day) and (B) the aggregate
principal amount of Swingline Loans to be made pursuant to such Borrowing.

          (ii)  Without in any way limiting the obligation of the Borrower to
confirm in writing any telephonic notice permitted to be given hereunder, the
Agent, the respective Issuing Bank (in the case of Letters of Credit) or the
Swingline Bank, as the case may be, may, prior to receipt of written
confirmation, act without liability upon the basis of telephonic notice believed
by the Agent, the respective Issuing Bank (in the case of Letters of Credit) or
the Swingline Bank, as the case may be, in good faith to be from the Chief
Executive Officer, President, Chief Financial Officer or Controller of the
Borrower.  In each such case, the Agent's, such Issuing Bank's or the Swingline
Bank's record of the terms of such telephonic notice shall be conclusive absent
manifest error.

          (iii) Mandatory Borrowings shall be made upon the notice specified in
Section 1.01(e), with the Borrower irrevocably agreeing, by its incurrence of
any Swingline Loan, to the making of the Mandatory Borrowings as set forth in
Section 1.01(e).

          1.04  Disbursement of Funds.  No later than 12:00 Noon (New York time)
                ---------------------                                           
on the date specified in each Notice of Borrowing (or (x) in the case of
Swingline Loans, no later than the close of business on the date specified
pursuant to Section 1.03(b)(i) or (y) in the case of Mandatory Borrowings, not
later than 12:00 Noon (New York time) on the date specified in Section 1.01(e)),
each Bank with a Commitment of the respective Tranche will make available its
pro rata portion (determined in accordance with Section 1.07) of each such
- --- ----                                                                  
Borrowing requested to be made on such date (or in the case of Swingline Loans,
the Swingline Bank shall make available the full amount thereof). All such
amounts shall be made available in Dollars and in immediately available funds at
the Payment Office, and the Agent will immediately make available to the
Borrower at the Payment Office the aggregate of the amounts so made available by
the Banks. Unless the Agent shall have been notified in writing by any Bank
prior to the date of Borrowing that

                                      -6-
<PAGE>
 
such Bank does not intend to make available to the Agent such Bank's portion of
any Borrowing to be made on such date, the Agent may assume that such Bank has
made such amount available to the Agent on such date of Borrowing and the Agent
may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. If such corresponding amount is not in fact made available
to the Agent by such Bank, the Agent shall be entitled to recover such
corresponding amount on demand from such Bank. If such Bank does not pay such
corresponding amount forthwith upon the Agent's demand therefor, the Agent shall
promptly notify the Borrower, and Borrower shall immediately pay such
corresponding amount to the Agent. The Agent shall also be entitled to recover
on demand from such Bank or Borrower, as the case may be, interest on such
corresponding amount in respect of each day from the date such corresponding
amount was made available by the Agent to such Borrower, until the date such
corresponding amount is recovered by the Agent, at a rate per annum equal to (i)
if recovered from such Bank, the Federal Funds Rate and (ii) if recovered from
either Borrower, the rate of interest applicable to the respective Borrowing,
as determined pursuant to Section 1.08. Nothing in this Section 1.04 shall be
deemed to relieve any Bank from its obligation to make Loans hereunder or to
prejudice any rights which Borrower may have against any Bank as a result of any
failure by such Bank to make Loans hereunder.

          1.05  Notes.  (a)  The Borrower's obligation to pay the principal of,
                -----

          (i)   except as otherwise provided in Section 1.10(b), Eurodollar
     Loans may be converted into Base Rate Loans only on the last day of an
     Interest Period applicable to the Loans being converted and no such partial

Borrowing(s) pursuant to which such Loans were made and, if to be converted into
Eurodollar Loans, the Interest Period to be initially applicable thereto.  The
Agent shall give each Bank prompt notice of any such proposed conversion
affecting any of its Loans.

                -------------------                                      
Swingline Loans) under this Agreement shall be incurred from the Banks pro rata
                                                                       --- ----

Borrowings of Revolving Loans made pursuant to a Mandatory Borrowing shall be
incurred by the Borrower from the Banks pro rata on the basis of their

Percentages. It is understood that no Bank shall be responsible for any default
by any other Bank of its obligation to make Loans hereunder and that each Bank
shall be obligated to make the Loans provided to be made by it hereunder
regardless of the failure of any other Bank to make its Loans hereunder.

          1.08  Interest.  (a)  The Borrower agrees to pay interest in respect
                --------                                                      
of the unpaid principal amount of each Base Rate Loan made to it from the date
of the Borrowing thereof (or with respect to Loans incurred prior to the
Restatement Effective Date, from the Restatement Effective Date,) until the
earlier of (i) the maturity thereof (whether by acceleration or otherwise) of
such Base Rate Loan and (ii) the conversion of such Base Rate Loan to a
Eurodollar Loan pursuant to Section 1.06, at a rate per annum which shall at all
times be equal to the sum of the Applicable Margin plus the Base Rate in effect
from time to time.

          (b)  The Borrower agrees to pay interest in respect of the unpaid
principal amount of each Eurodollar Loan made to it from the date of the
Borrowing thereof (or with respect to Loans incurred prior to the Restatement
Effective Date, from the Restatement Effective Date) until the earlier of (i)
the maturity thereof (whether by acceleration or otherwise) of such Eurodollar
Loan and (ii) the conversion of such Eurodollar Loan to a Base Rate Loan
pursuant to Section 1.06, 1.09 or 1.10(b), as applicable, at a rate per annum
which shall, during each Interest Period applicable thereto, be equal to the sum
of the Applicable Margin plus the Quoted Rate for such Interest Period.

          (c)  Overdue principal and, to the extent permitted by law, overdue
interest in respect of each Loan and any other overdue amount payable hereunder
shall, in each case, bear interest at a rate per annum equal to the greater of
(x) 2% per annum in excess of the rate otherwise applicable to Base Rate Loans
of the respective Tranche of Loans from time to time and (y) the rate which is
2% in excess of the rate borne by such Loans.  Interest which accrues under this
Section 1.08(c) shall be payable on demand.

          (d)  Accrued (and theretofore unpaid) interest shall be payable (i) in
respect of each Base Rate Loan, quarterly in arrears on each Quarterly Payment
Day, (ii) in respect of each Eurodollar Loan on (x) the date of any prepayment
or repayment thereof (on the amount prepaid or repaid), (y) the date of any
conversion into a Base Rate Loan pursuant to Section 1.06, 1.09 or 1.10(b), as
applicable (on the amount converted) and (z) on the last day of each Interest
Period applicable thereto and, in the case of an Interest Period in excess of
three months, on each date occurring at three month intervals after the first
day of such Interest Period and (iii) in respect of each Loan, at maturity
(whether by acceleration or otherwise) and, after such maturity, on demand.
Notwithstanding anything to the contrary in this Agreement or in the Original
Credit Agreement, all accrued (but theretofore unpaid) interest with respect to
Loans which were outstanding prior to the Restatement Effective Date shall be
payable on the Restatement Effective Date.

          (e)  Upon each Interest Determination Date, the Agent shall determine
the Quoted Rate for the Interest Period applicable to Eurodollar Loans and shall
promptly notify the Borrower and the Banks thereof.  Each such determination
shall, absent manifest error, be final and conclusive and binding on all parties
hereto.

                ----------------                                               
or Notice of Conversion in respect of the making of, or conversion into, a
Eurodollar Loan (in the case of the initial Interest Period applicable thereto)
or prior to 11:00 A.M. (New York time) on the third Business Day prior to the
expiration of an Interest Period applicable to such Eurodollar Loan (in the case
of any subsequent Interest Period), the Borrower shall have the right to elect,
by giving the Agent notice thereof, the interest period (each an "Interest
Period") applicable to such Eurodollar Loan, which Interest Period shall, at the
option of the Borrower, be a one, two, three or six-month period; provided that:
                                                                  --------      

          (i)   all Eurodollar Loans comprising a single Borrowing shall at
     all times have the same Interest Period;

          (ii)  the initial Interest Period for any Eurodollar Loan shall
     commence on the date of Borrowing of such Loan (including the date of any
     conversion thereto from a Borrowing of Base Rate Loans) and each Interest
     Period occurring thereafter in respect of such Loan shall commence on the
     day on which the next preceding Interest Period applicable thereto expires;

          (iii) if any Interest Period relating to a Eurodollar Loan begins
     on a day for which there is no numerically corresponding day in the
     calendar month at the end of such Interest Period, such Interest Period
     shall end on the last Business Day of such calendar month;

          (iv)  if any Interest Period would otherwise expire on a day which
     is not a Business Day, such Interest Period shall expire on the next
     succeeding Business Day; provided, however, that if any Interest Period for
                              --------  -------                                 
     a Eurodollar Loan would otherwise expire on a day which is not a Business
     Day but is a day of the month after which no further Business Day occurs in
     such month, such Interest Period shall expire on the next preceding
     Business Day;

          (v)   no Interest Period for a Borrowing under a Tranche shall be
     selected which extends beyond the respective Maturity Date of such Tranche;

          (vi)  no Interest Period may be selected at any time when any
     Default or Event of Default is then in existence;


          (vii) no Interest Period in respect of any Borrowing of Term Loans
     or Acquisition Loans, as the case may be, shall be selected which extends
     beyond any date upon which a mandatory repayment of such Term Loans or
     Acquisition Loans 

                                      -11-
<PAGE>
 
     will be required to be made under Section 4.02(A)(c) or (d), as the case
     may be, if, after giving effect to the selection of such Interest Period,
     the aggregate principal amount of such Term Loans or Acquisition Loans, as
     the case may be, maintained as Eurodollar Loans which have Interest Periods
     expiring after such date will be in excess of the aggregate principal
     amount of such Term Loans or Acquisition Loans, as the case may be, then
     outstanding less the aggregate amount of such required prepayment; and

          (viii)  no Interest Period may be selected prior to the Syndication
     Termination Date.

If upon the expiration of any Interest Period applicable to a Borrowing of
Eurodollar Loans the Borrower has failed to elect a new Interest Period to be
applicable to such Eurodollar Loans as provided above or a Default or Event of
Default then exists, the Borrower shall be deemed to have elected to convert
such Eurodollar Loans into Base Rate Loans effective as of the expiration date
of such current Interest Period.

          1.10  Increased Costs, Illegality, etc.  (a)  In the event that any
                ---------------------------------                            
Bank shall have determined (which determination shall, absent manifest error, be
final and conclusive and binding upon all parties hereto but, with respect to
clause (i) below, may be made only by the Agent):

          (i)   on any Interest Determination Date that, by reason of any
     changes arising after the date of this Agreement affecting the interbank
     Eurodollar market, adequate and fair means do not exist for ascertaining
     the applicable interest rate on the basis provided for in the definition of
     Quoted Rate; or

          (ii)  at any time, that such Bank shall incur increased costs or
     reductions in the amounts received or receivable hereunder with respect to
     any Eurodollar Loan because of (x) any change since the date of this
     Agreement in any applicable law or governmental rule, regulation, order,
     guideline or request (whether or not having the force of law) or in the
     interpretation or administration thereof and including the introduction of
     any new law or governmental rule, regulation, order, guideline or request,
     such as, for example, but not limited to: (A) a change in the basis of
     taxation of payments to any Bank of the principal of or interest on the
     Notes or any other amounts payable hereunder (except for changes in the
     rate of tax on, or determined by reference to, the net income or profits of
     such Bank imposed by the jurisdiction in which its principal office or
     applicable lending office is located) or (B) a change in official reserve
     requirements (but, in all events, excluding reserves required under
     Regulation D to the extent included in the computation of the Quoted Rate)
     and/or (y) other circumstances since the date of this Agreement

                                      -12-
<PAGE>
 
     affecting such Bank or the interbank Eurodollar market or the position of
     such Bank in such market; or

          (iii)  at any time, that the making or continuance of any
     Eurodollar Loan has been made (x) unlawful by any law or governmental rule,
     regulation or order, (y) impossible by compliance by any Bank in good faith
     with any governmental request (whether or not having the force of law) or
     (z) impracticable as a result of a contingency occurring after the date of
     this Agreement which materially and adversely affects the interbank
     Eurodollar market;

then, and in any such event, such Bank (or the Agent, in the case of clause (i)
above) shall promptly give notice (if by telephone, promptly confirmed in
writing) to the Borrower, and, except in the case of clause (i) above, to the
Agent of such determination (which notice the Agent shall promptly transmit to
each of the other Banks).  Thereafter (x) in the case of clause (i) above,
Eurodollar Loans shall no longer be available until such time as the Agent
notifies the Borrower and the Banks that the circumstances giving rise to such
notice by the Agent no longer exist, and any Notice of Borrowing or Notice of
Conversion given by the Borrower with respect to Eurodollar Loans which have not
yet been incurred (including by way of conversion) shall be deemed rescinded by
the Borrower, (y) in the case of clause (ii) above, the Borrower shall pay to
such Bank, upon written demand therefor, such additional amounts (in the form
of an increased rate of, or a different method of calculating, interest or
otherwise as such Bank in its sole discretion shall determine) as shall be
required to compensate such Bank for such increased costs or reductions in
amounts received or receivable hereunder (a written notice as to the additional
amounts owed to such Bank, showing in reasonable detail the basis for the
calculation thereof, submitted to the Borrower by such Bank shall, absent
manifest error, be final and conclusive and binding on all the parties hereto)
and (z) in the case of clause (iii) above, the Borrower shall take one of the
actions specified in Section 1.10(b) as promptly as possible and, in any event,
within the time period required by law.

          (b)  At any time that any Eurodollar Loan is affected by the
circumstances described in Section 1.10(a)(ii) or (iii), the Borrower may (and
in the case of a Eurodollar Loan affected by the circumstances described in
Section 1.10(a)(iii) shall) either (i) if the affected Eurodollar Loan is then
being made initially or pursuant to a conversion, by giving the Agent telephonic
notice (confirmed in writing) on the same date that such Borrower was notified
by the affected Bank or the Agent pursuant to Section 1.10(a)(ii) or (iii),
cancel the respective Borrowing or conversion, or (ii) if the affected
Eurodollar Loan is then outstanding, upon at least three Business Days' written
notice to the Agent, require the affected Bank to convert such Eurodollar Loan
into a Base Rate Loan; provided that if more than one Bank is affected at any
                       --------
time, then all affected Banks must be treated the same pursuant to this Section
1.10(b).

          (c)  If any Bank shall have determined that after the date hereof, the
adoption or effectiveness of any applicable law, rule or regulation regarding
capital adequacy, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by such Bank or any corporation controlling such Bank with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Bank's or such other corporation's
capital or assets as a consequence of such Bank's Commitment or Commitments
hereunder or its obligations hereunder to a level below that which such Bank or
such other corporation could have achieved but for such adoption, effectiveness,
change or compliance (taking into consideration such Bank's or such other
corporation's policies with respect to capital adequacy), then from time to
time, upon written demand by such Bank (with a copy to the Agent), accompanied
by the notice referred to in the second to the last sentence of this clause (c),
the Borrower shall pay to such Bank such additional amount or amounts as will
compensate such Bank or such other corporation for such reduction.  In
determining such additional amounts, each Bank will act reasonably and in good
faith and will use reasonable averaging and attribution methods.  Each Bank,
upon determining that any additional amounts will be payable pursuant to this
Section 1.10(c), will give prompt written notice thereof to the Borrower (a copy
of which shall be sent by such Bank to the Agent), which notice shall set forth
the basis of the calculation of such additional amounts, although the failure to
give any such notice shall not release or diminish the Borrower's obligations to
pay additional amounts pursuant to this Section 1.10(c) upon the subsequent
receipt of such notice.  A Bank's reasonable good faith determination of
compensation owing under this Section 1.10(c) shall, absent manifest error, be
final and conclusive and binding on all the parties hereto.

          1.11  Compensation.  The Borrower shall compensate each Bank, upon its
                ------------                                                    
written request (which request shall set forth in reasonable detail the basis
for requesting such compensation), for all losses, expenses and liabilities
(including, without limitation, any loss, expense or liability incurred by
reason of the liquidation or reemployment of deposits or other funds required by
such Bank to fund its Eurodollar Loans) which such Bank may sustain:  (i) if for
any reason (other than a default by such Bank or the Agent) a Borrowing of, or
conversion from or into, Eurodollar Loans does not occur on a date specified
therefor in a Notice of Borrowing or Notice of Conversion (whether or not
withdrawn by such Borrower or deemed withdrawn pursuant to Section 1.10(a));
(ii) if any repayment (including any repayment made pursuant to Section 4.02 or
as a result of an acceleration of the Loans pursuant to Section 10 or as a
result of the replacement of a Bank pursuant to Section 1.12) or conversion of
any of its Eurodollar Loans occurs on a date which is not the last day of an
Interest Period with respect thereto; (iii) if any prepayment of any of its
Eurodollar Loans is not made on any date specified in a notice of prepayment
given by such Borrower; or (iv) as a consequence of (x) any other default by the
Borrower

                                      -14-
<PAGE>
 
to repay its Loans when required by the terms of this Agreement or any Note held
by such Bank or (y) any election made pursuant to Section 1.10(b). A Bank's
basis for requesting compensation pursuant to this Section, and a Bank's
calculations of the amount thereof, shall, absent manifest error, be final and
conclusive and binding on all the parties hereto.

          1.12  Replacement of Banks.  (x) If any Bank becomes a Defaulting Bank
                --------------------                                            
or otherwise defaults in its obligations to make Loans or fund Unpaid Drawings,
or (y) if any Bank (other than the Agent) refuses to consent to certain proposed
changes, waivers, discharges or terminations with respect to this Agreement
which have been approved by the Required Banks as provided in Section 14.12(b),
then the Borrower shall have the right, if no Default or Event of Default then
exists, to replace such Bank (the "Replaced Bank") with any other Bank or with
one or more Eligible Transferee or Transferees, none of whom shall constitute a
Defaulting Bank or shall be in default in its obligations to make Loans or fund
Unpaid Drawings at the time of such replacement (collectively, the "Replacement
Banks") reasonably acceptable to the Agent, the Swingline Bank and each Issuing
Bank with outstanding Letters of Credit (unless the respective Replacement Bank
is not acquiring any Revolving Loan Commitment); provided that:
                                                 --------      

          (i)  at the time of any replacement pursuant to this Section 1.12,
     the Replacement Bank shall enter into one or more assignment agreements
     pursuant to Section 14.04(b) (and with all fees payable pursuant to said
     Section 14.04(b) to be paid by the Replacement Bank) pursuant to which the
     Replacement Bank shall acquire all of the Commitments and outstanding Loans
     of, and participations in Letters of Credit by, the Replaced Bank and, in
     connection therewith, shall pay to (x) the Replaced Bank in respect thereof
     an amount equal to the sum of (A) an amount equal to the principal of, and
     all accrued interest on, all outstanding Loans of the Replaced Bank, and
     (B) an amount equal to such Replaced Bank's Percentage of all Unpaid
     Drawings that have been funded by (and not reimbursed to) such Replaced
     Bank, together with all then unpaid interest with respect thereto at such
     time and (C) an amount equal to all accrued, but theretofore unpaid, Fees
     owing to the Replaced Bank pursuant to Section 3.01 hereof, (y) the Issuing
     Bank or Banks an amount equal to such Replaced Bank's Percentage of any
     Unpaid Drawing (which at such time remains an Unpaid Drawing) to the extent
     such amount was not theretofore funded by such Replaced Bank and (z) the
     Swingline Bank an amount equal to such Bank's Percentage of any Mandatory
     Borrowing to the extent such amount was not theretofore funded by such
     Replaced Bank; and

          (ii) all obligations of the Borrower owing to the Replaced Bank
     (other than those specifically described in clause (i) above in respect of
     which the assignment purchase price has been, or is concurrently being,
     paid) shall be paid in full by the Borrower to such Replaced Bank
     concurrently with such replacement.

                                      -15-

Upon the execution of the respective assignment documentation, the payment of
amounts referred to in clauses (i) and (ii) above, recordation of the assignment
on the Register by the Agent pursuant to Section 8.16 and, if so requested by
the Replacement Bank, delivery to the Replacement Bank of the appropriate Notes
executed by the Borrower, the Replacement Bank shall become a Bank hereunder
and the Replaced Bank shall cease to constitute a Bank hereunder with respect to
the Loans and Commitments so transferred, except with respect to indemnification
provisions under this Agreement, which shall survive as to such Replaced Bank
and the Percentages of the Banks shall be automatically adjusted at such time to
the extent necessary to give effect to such replacement.

                      ----------------- 

          2.01  Letters of Credit.  (a)  Subject to and upon the terms and
                -----------------                                         
conditions herein set forth, the Borrower may request any Issuing Bank at any
time and from time to time after the Initial Borrowing Date and prior to the
tenth Business Day immediately preceding the Revolving Loan Maturity Date to
issue, for the account of the Borrower and for the benefit of any holder (or any
trustee, agent or other similar representative for any such holders) of L/C
Supportable Indebtedness, an irrevocable standby letter of credit in a form
customarily used by such Issuing Bank or in such other form as has been approved
by such Issuing Bank in support of said L/C Supportable Indebtedness (each such
letter of credit, a "Letter of Credit" and, collectively, the "Letters of
Credit").  All Letters of Credit shall be denominated in Dollars.

     (b)  Each Issuing Bank (other than Banque Paribas) may agree in its sole
discretion and Banque Paribas hereby agrees that it will (subject to the terms
and conditions contained herein), at any time and from time to time after the
Initial Borrowing Date and prior to the Revolving Loan Maturity Date, following
its receipt of the respective Letter of Credit Request, issue for the account of
the Borrower one or more Letters of Credit in support of such L/C Supportable
Indebtedness as is permitted to remain outstanding without giving rise to a
Default or Event of Default hereunder; provided that the respective Issuing Bank
                                       --------                                 
shall be under no obligation to issue any Letter of Credit if at the time of
such issuance:

          (i) any order, judgment or decree of any governmental authority or
     arbitrator shall purport by its terms to enjoin or restrain such Issuing
     Bank from issuing such Letter of Credit or any requirement of law
     applicable to such Issuing Bank or any request or directive (whether or not
     having the force of law) from any governmental authority with jurisdiction
     over such Issuing Bank shall prohibit, or request that such Issuing Bank
     refrain from, the issuance of letters of credit generally or such Letter of
     Credit in particular or shall impose upon such Issuing Bank with respect to
     such Letter of Credit any restriction or reserve or capital requirement
     (for which such Issuing Bank is not otherwise compensated) not in effect on
     the date

                                      -16-

     hereof, or any unreimbursed loss, cost or expense which was not applicable,
     in effect or known to such Issuing Bank as of the date hereof and which
     such Issuing Bank in good faith deems material to it;

          (ii)  such Issuing Bank shall have received a notice of the type
     described in the second sentence of Section 2.03(b) from any Bank prior to
     the issuance of such Letter of Credit; or

          (iii) a Bank Default exists, unless such Issuing Bank has entered
     into arrangements satisfactory to it and the Borrower to eliminate such
     Issuing Bank's risk with respect to the Bank which is the subject of the
     Bank Default, including by cash collateralizing such Bank's Percentage of
     the Letter of Credit Outstandings.

          (c)   Notwithstanding the foregoing, (i) no Letter of Credit shall be
issued the Stated Amount of which, when added to the Letter of Credit
Outstandings (exclusive of Unpaid Drawings which are repaid on the date of,
prior to the issuance of, the respective Letter of Credit) at such time, would
exceed (x) $2,000,000 or (y) when added to the aggregate principal amount of all
Revolving Loans then outstanding and Swingline Loans then outstanding, the
lesser of (A) the Total Revolving Loan Commitment then in effect (after giving
effect to any reductions to the Total Revolving Loan Commitment on such date) or
(B) the Borrowing Base at such time and (ii) each Letter of Credit shall by its
terms terminate on or before the earlier of (x) the date which occurs 12 months
after the date of the issuance thereof (although the Letter of Credit issued in
connection with the acquisition of the Greater Cincinnati Gastro-Intestinal
Medical Practice may terminate 18 months after the date of the issuance thereof
and any other Letter of Credit may be renewable for successive periods of up to
12 months, but not beyond the Revolving Loan Maturity Date, on terms acceptable
to the Issuing Bank) and (y) the tenth Business Day immediately preceding the
Revolving Loan Maturity Date.

          2.02  Minimum Stated Amount.  The Stated Amount of each Letter of
                ---------------------                                      
Credit shall be not less than $100,000 or such lesser amount as is acceptable to
the Issuing Bank and in no event shall there be more than five Letters of Credit
outstanding at any time or such greater amount as is acceptable to the Issuing
Bank.

          2.03  Letter of Credit Requests.  (a)  Whenever the Borrower desires
                -------------------------                                     
that a Letter of Credit be issued for its account, the Borrower shall give the
Agent and the respective Issuing Bank at least 10 Business Days' (or such
shorter period as is acceptable to the respective Issuing Bank in any given
case) written notice prior to the proposed date of issuance (which shall be a
Business Day). Each notice shall be in the form of Exhibit C (each a "Letter of
Credit Request").

                                      -17-
<PAGE>
 
          (b)  The making of each Letter of Credit Request shall be deemed to be
a representation and warranty by the Borrower that such Letter of Credit may be
issued in accordance with, and will not violate the requirements of, Section
2.01(c).  Unless the Issuing Bank has received notice from any Bank before it
issues a Letter of Credit that one or more of the conditions specified in
Section 6 are not then satisfied, or that the issuance of such Letter of Credit
would violate Section 2.01(c), then such Issuing Bank may issue the requested
Letter of Credit for the account of the Borrower in accordance with the Issuing
Bank's usual and customary practices.

          2.04 Letter of Credit Participations.  (a)  Immediately upon the
               -------------------------------                            
issuance by the respective Issuing Bank of any Letter of Credit, such Issuing
Bank shall be deemed to have sold and transferred to each Bank with a Revolving
Loan Commitment, other than such Issuing Bank (each such Bank, in its capacity
under this Section 2.04, a "Participant"), and each such Participant shall be
deemed irrevocably and unconditionally to have purchased and received from such
Issuing Bank, without recourse or warranty, an undivided interest and
participation, to the extent of such Participant's Percentage in such Letter of
Credit, each substitute letter of credit, each drawing made thereunder and the
obligations of the Borrower under this Agreement with respect thereto, and any
security therefor or guaranty pertaining thereto.  Upon any change in the
Revolving Loan Commitments of the Banks pursuant to Section 14.04 or on the
Restatement Effective Date, it is hereby agreed that, with respect to all
outstanding Letters of Credit and Unpaid Drawings, there shall be an automatic
adjustment to the participations pursuant to this Section 2.04 to reflect the
new Percentages of the assignor and assignee Bank or of all Banks with Revolving
Loan Commitments, as the case may be.

          (b)  In determining whether to pay under any Letter of Credit, the
Issuing Bank shall not have any obligation relative to the respective
Participants other than to confirm that any documents required to be delivered
under such Letter of Credit appear to have been delivered and that they appear
to comply on their face with the requirements of such Letter of Credit.  Any
action taken or omitted to be taken by any Issuing Bank under or in connection
with any Letter of Credit if taken or omitted in the absence of gross negligence
or willful misconduct, shall not create for such Issuing Bank any resulting
liability to the Borrower, any Bank, any Participant or any other Person.

          (c)  In the event that any Issuing Bank makes any payment under any
Letter of Credit and the Borrower shall not have reimbursed such amount in full
to the Issuing Bank pursuant to Section 2.05(a), such Issuing Bank shall
promptly notify the Agent, which shall promptly notify each Participant of such
failure, and each Participant shall promptly and unconditionally pay to the
Agent for the account of such Issuing Bank the amount of such Participant's
Percentage of such unreimbursed payment in Dollars and in same day funds. If the
Agent so notifies, prior to 11:00 A.M. (New York time) on any Business Day, any
Participant required to fund a payment under a Letter of Credit, such
Participant

                                      -18-
<PAGE>
 
shall make available to the Agent at the Payment Office of the Agent for the
account of such Issuing Bank in Dollars such Participant's Percentage of the
amount of such payment on such Business Day in same day funds. If and to the
extent such Participant shall not have so made its Percentage of the amount of
such payment available to the Agent for the account of such Issuing Bank, such
Participant agrees to pay to the Agent for the account of such Issuing Bank,
forthwith on demand such amount, together with interest thereon, for each day
from such date until the date such amount is paid to the Agent for the account
of such Issuing Bank at the Federal Funds Rate. The failure of any Participant
to make available to the Agent for the account of such Issuing Bank its
Percentage of any payment under any Letter of Credit shall not relieve any other
Participant of its obligation hereunder to make available to the Agent for the
account of such Issuing Bank its Percentage of any Letter of Credit on the date
required, as specified above, but no Participant shall be responsible for the
failure of any other Participant to make available to the Agent for the account
of such Issuing Bank such other Participant's Percentage of any such payment.

          (d)  Whenever any Issuing Bank receives a payment of a reimbursement
obligation as to which the Agent has received for the account of such Issuing
Bank any payments from the Participants pursuant to clause (c) above, such
Issuing Bank shall pay to the Agent and the Agent shall promptly pay each
Participant which has paid its Percentage thereof, in Dollars and in same day
funds, an amount equal to such Participant's share (based on the proportionate
aggregate amount funded by such Participant to the aggregate amount funded by
all Participants) of the principal amount of such reimbursement obligation and
interest thereon accruing after the purchase of the respective participations.

          (e)  The obligations of the Participants to make payments to the Agent
for the account of each Issuing Bank with respect to Letters of Credit issued
shall be irrevocable and not subject to any qualification or exception
whatsoever and shall be made in accordance with the terms and conditions of this
Agreement under all circumstances, including, without limitation, any of the
following circumstances:

          (i)  any lack of validity or enforceability of this Agreement or any
     of the Credit Documents;

          (ii) the existence of any claim, setoff, defense or other right which
     the Borrower may have at any time against a beneficiary named in a Letter
     of Credit, any transferee of any Letter of Credit (or any Person for whom
     any such transferee may be acting), the Agent, any Participant, or any
     other Person, whether in connection with this Agreement, any Letter of
     Credit, the transactions contemplated herein or any unrelated transactions
     (including any underlying transaction between the Borrower and the
     beneficiary named in any such Letter of Credit);

                                      -19-
<PAGE>
 
          (iii) any draft, 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)  the surrender or impairment of any security for the
     performance or observance of any of the terms of any of the Credit
     Documents; or

          (v)   the occurrence of any Default or Event of Default.

          2.05  Agreement to Repay Letter of Credit Drawings.  (a)  The Borrower
                --------------------------------------------                    
hereby agrees to reimburse the respective Issuing Bank, by making payment to the
Agent in immediately available funds at the Payment Office (or by making the
payment directly to such Issuing Bank at such location as may otherwise have
been agreed upon by the Borrower and such Issuing Bank), for any payment or
disbursement made by such Issuing Bank under any Letter of Credit (each such
amount so paid until reimbursed, an "Unpaid Drawing"), immediately after, and in
any event on the date of, notification by the Issuing Bank to the Borrower of
such payment or disbursement, with interest on the amount so paid or disbursed
by such Issuing Bank, to the extent not reimbursed prior to 12:00 Noon (New York
time) on the date of such payment or disbursement, from and including the date
paid or disbursed to but excluding the date such Issuing Bank is reimbursed by
the Borrower therefor at a rate per annum which shall be the Base Rate in effect
from time to time plus 1-3/4% until the date on which the Borrower is so
notified and 3-3/4% thereafter, in each case with such interest to be payable on
demand.

          (b)   The obligations of the Borrower under this Section 2.05 to
reimburse the respective Issuing Bank with respect to Unpaid Drawings
(including, in each case, interest thereon) shall be absolute and unconditional
under any and all circumstances and irrespective of any setoff, counterclaim or
defense to payment which the Borrower may have or have had against any Bank
(including in its capacity as Issuing Bank or as Participant), including,
without limitation, any defense based upon the failure of any drawing under a
Letter of Credit (each a "Drawing") to conform to the terms of the Letter of
Credit or any nonapplication or misapplication by the beneficiary of the
proceeds of such Drawing; provided, however, that the Borrower shall not be
                          --------  -------                                
obligated to reimburse any Issuing Bank for any wrongful payment made by such
Issuing Bank under a Letter of Credit as a result of acts or omissions
constituting willful misconduct or gross negligence on the part of such Issuing
Bank.

          2.06  Increased Costs.  If at any time after the date hereof any
                ---------------                                           
Issuing Bank or any Participant determines that the introduction of or any
change in any applicable law, rule, regulation, order, guideline or request or
in the interpretation or administration thereof by any governmental authority
charged with the interpretation or administration thereof, or compliance by such
Issuing Bank or any Participant, or any corporation controlling such

                                      -20-
<PAGE>
 
Person, with any request or directive by any such authority (whether or not
having the force of law), shall either (i) impose, modify or make applicable any
reserve, deposit, capital adequacy or similar requirement against letters of
credit issued by such Issuing Bank or participated in by any Participant, or
(ii) impose on such Issuing Bank or any Participant, or any corporation
controlling such Person, any other conditions relating, directly or indirectly,
to this Agreement or any Letter of Credit; and the result of any of the
foregoing is to increase the cost to such Issuing Bank or any Participant of
issuing, maintaining or participating in any Letter of Credit, or reduce the
amount of any sum received or receivable by such Issuing Bank or any Participant
hereunder or reduce the rate of return on its capital with respect to Letters of
Credit, then, upon demand to the Borrower by such Issuing Bank or any
Participant (a copy of which demand shall be sent by such Issuing Bank or such
Participant to the Agent), the Borrower shall pay to such Issuing Bank or such
Participant such additional amount or amounts as will compensate such Bank for
such increased cost or reduction in the amount receivable or reduction on the
rate of return on its capital. Such Issuing Bank or any Participant, upon
determining that any additional amounts will be payable pursuant to this
Section 2.06, will give prompt written notice thereof to the Borrower, which
notice shall include a certificate submitted to the Borrower by such Issuing
Bank or such Participant (a copy of which certificate shall be sent by such
Issuing Bank or such Participant to the Agent), setting forth in reasonable
detail the basis for the calculation of such additional amount or amounts
necessary to compensate such Issuing Bank or such Participant, although failure
to give any such notice shall not release or diminish the Borrower's obligations
to pay additional amounts pursuant to this Section 2.06. The certificate
required to be delivered pursuant to this Section 2.06 shall, absent manifest
error, be final, conclusive and binding on Holdings.

          Section 3.  Fees; Reductions of Commitment.
                      ------------------------------ 

          3.01  Fees.  (a)  The Borrower agrees to pay to the Agent for

distribution to each Bank with a Revolving Loan Commitment, a Term Loan
Commitment or an Acquisition Loan Commitment a commitment commission (the
"Commitment Commission") for the period from and including the Restatement

Loan Commitment and the Acquisition Loan  Commitment and 3% per annum with
respect to the Term Loan Commitment on the daily Aggregate Unutilized Commitment
of such Bank.  Accrued Commitment Commission shall be due and payable quarterly
in arrears on each Quarterly Payment Date and on the Revolving Loan Maturity

          (b)   The Borrower agrees to pay to each Issuing Bank, for its own
account, a facing fee in respect of each Letter of Credit issued by such Issuing
Bank hereunder (the 

                                      -21-
<PAGE>
 
"Facing Fee"), for the period from and including the date of issuance of such
Letter of Credit to and including the date of termination of such Letter of
Credit, equal to 1/4 of 1% per annum of the daily Stated Amount of such Letter
of Credit; provided that in no event shall the annual Facing Fee with respect to

including the date of issuance of such Letter of Credit to and including the
date of termination of such Letter of Credit, computed at a rate per annum equal
to the Applicable Margin for Revolving Loans which are maintained as Eurodollar
Loans of the daily Stated Amount of such Letter of Credit.  Letter of Credit
Fees shall be distributed by the Agent to the Banks on the basis of the
respective Percentages as in effect from time to time.  Accrued Letter of Credit
Fees shall be due and payable quarterly in arrears on each Quarterly Payment
Date and on the first date after the termination of the Total Revolving Loan
Commitment on which no Letters of Credit remain outstanding.

          (d)  The Borrower hereby agrees to pay in immediately available funds
directly to the Issuing Bank upon each issuance of, drawing under, and/or
amendment of, a Letter of Credit issued by the Issuing Bank such amount as shall
at the time of such issuance, drawing or amendment be the administrative charge
which the Issuing Bank is customarily charging for issuances of, drawings under
(including wire charges) or amendments of, letters of credit issued by it or
such alternative amounts as may have been agreed upon in writing by the Borrower
and the Issuing Bank.

          (e)  The Borrower shall pay to the Agent when and as due, for its own
account, such fees as may be agreed to in writing from time to time between the
Borrower and the Agent.

          (f)  Notwithstanding anything to the contrary contained in this
Agreement or in the Original Credit Agreement, all unpaid Fees under, and as
defined in, the Original Credit Agreement (including, without limitation,
Commitment Commissions (as defined in the Original Credit Agreement)) accrued
prior to the Restatement Effective Date shall be payable on the Restatement
Effective Date.

                -----------------------------------------------               
least three Business Days' prior written notice (or telephonic notice promptly
confirmed in writing) to the Agent at its Notice Office (which notice the Agent
shall promptly transmit to each of the Banks), the Borrower shall have the
right, without premium or penalty, to terminate or reduce the Total Acquisition
Loan Commitment and/or the Total Revolving Loan Commitment, in whole or in part;
provided that (i) each such reduction shall apply proportionately to reduce the

Agreement which have been approved by the Required Banks as provided in Section
14.12(b), the Borrower shall have the right, upon five Business Days' prior
written notice to the Agent at its Notice Office (which notice the Agent shall
promptly transmit to each of the Banks), to terminate all of the Acquisition
Loan Commitment and/or the Revolving Loan Commitment of such Bank, so long as
all Loans, together with accrued and unpaid interest, Fees and all other
amounts, owing to such Bank (other than amounts owing in respect of any Tranche
of Term Loans or Acquisition Loans maintained by such Bank, if such Term Loans
or Acquisition Loans are not being repaid pursuant to Section 14.12(b)) are
repaid concurrently with the effectiveness of such termination pursuant to
Section 4.01(b) and the Borrower shall pay to the Agent at such time an amount
in cash and/or Cash Equivalents equal to such Bank's applicable Percentage of
the outstanding Letters of Credit (which cash and/or Cash Equivalents shall be
held by the Agent as security for the obligations of the Borrower hereunder in
respect of the outstanding Letters of Credit pursuant to a cash collateral
agreement to be entered into in form and substance reasonably satisfactory to
the Agent (at which time Part A of Schedule I shall be deemed modified to
reflect such changed amounts), and at such time, unless the respective Bank
continues to act as a Bank with respect to any Tranche of Term Loans or
Acquisition Loans or has a Revolving Loan Commitment, or  Acquisition Loan
Commitment hereunder, such Bank shall no longer constitute a "Bank" for purposes
of this Agreement, except with respect to indemnifications and similar
provisions under this Agreement, which shall survive as to such repaid Bank.

          3.03  Mandatory Reduction of Commitments.  (a)  The Total Commitment
                ----------------------------------

          (b)   In addition to any other mandatory commitment reductions
pursuant to this Section 3.03, the Total Term Loan Commitment (and the Term Loan
Commitment of each Bank with such a Commitment) shall (i) be reduced on the
Initial Borrowing Date 

                                      -23-

principal is made on the DVI Indebtedness, be reduced in an amount equal to the
amount of such payment, and (v) terminates in its entirety on the Term Loan

such date). Notwithstanding anything to the contrary contained in this
Agreement, after giving effect to the Restatement Effective Date and the
conversion of Acquisition Loans to Term Loans the Total Term Loan Commitment
shall be $8 million.

          (c)  In addition to any other mandatory commitment reductions pursuant
to this Section 3.03, the Total Acquisition Loan Commitment (and the Acquisition
Loan Commitment of each Bank with such a Commitment) shall (i) be reduced on
each date on which a Borrowing of Acquisition Loans is effected by an amount
equal to the amount of such Borrowing of Acquisition Loans made on such date,
(ii) terminate in its entirety on the Acquisition Loan Termination Date (after

required by Section 4.02; provided, however notwithstanding any mandatory

commitment reductions pursuant to this Section 3.03, the Total Acquisition Loan
Commitment on the Restatement Effective Date shall be $32.5 million.  In
addition, notwithstanding any other mandatory commitment reduction pursuant to
this Section 3.03, on the date that Holdings applies any proceeds from the
initial public offering of common equity of Holdings to repay Acquisition Loans,
the Total Acquisition Loan Commitment (and the Acquisition Loan Commitment of
each Bank with such a Commitment) shall be increased by an amount equal to the
amount of Acquisition Loans repaid on such date.

          (d)  In addition to any other mandatory commitment reductions pursuant
to this Section 3.03, the Total Revolving Loan Commitment (and the Revolving
Loan Commitment of each Bank) shall terminate on the Revolving Loan Maturity
Date.

          (e)  In addition to any other mandatory commitment reductions pursuant
to this Section 3.03, the Total Revolving Loan Commitment (and the Revolving
Loan Commitment of each Bank with such a Commitment) shall be reduced at the
time any payment is required to be made on the principal amount of Revolving
Loans (or would be required to be made if Revolving Loans were then outstanding)

public offering of Holdings common stock), by an amount equal to the maximum
amount of Revolving Loans that would be required to be repaid pursuant to
Section 4.02(B)(a) assuming that Revolving

                                      -24-

Loans were outstanding in an aggregate principal amount equal to the Total
Revolving Loan Commitment.

          (f)  In addition to any other mandatory commitment reductions pursuant
to this Section 3.03, the Total Acquisition Loan Commitment (and the Acquisition
Loan Commitment of each Bank with such a Commitment) shall be reduced at the
time any payment is required to be made on the principal amount of Acquisition
Loans (or would be required to be made of Acquisition Loans then outstanding)
pursuant to Section 4.02(B)(a) (except in the case of proceeds from the initial
public offering of Holdings common stock), by an amount equal to the maximum
amount of Acquisition Loans that would be required to be repaid pursuant to
Section 4.02(B)(a) assuming that Acquisition Loans were outstanding in an
aggregate principal amount equal to the Total Acquisition Loan Commitment.

          (g)  Each reduction (or increase in accordance with Section in 3.03)
to the Total Term Loan Commitment, the Total Acquisition Loan Commitment and the
Total Revolving Loan Commitment, pursuant to this Section 3.03 shall be applied
proportionately to reduce (or increase, as the case may be) the Term Loan
Commitment, the Acquisition Loan Commitment or the Revolving Loan Commitment, as
the case may be, of each Bank with such a Commitment.

any amounts are payable in respect of Taxes pursuant to the preceding sentence,
then the Borrower and Holdings shall jointly and severally be obligated to
reimburse each Bank, upon the written request of such Bank, for taxes imposed on

jurisdiction or any political subdivision or taxing authority thereof or therein
in which the principal office or applicable lending office of such Bank is
located as such Bank shall determine are payable by such Bank in respect of such
amounts so paid to or on behalf of such Bank pursuant to the preceding sentence
and in respect of any amounts paid to or on behalf of such Bank pursuant to this
sentence. The Borrower or Holdings, as the case may be, will furnish to the
Agent within 45 days after the date of the payment of any Taxes due pursuant to
applicable law certified copies of tax receipts evidencing such payment by the
Borrower or Holdings. The Borrower and Holdings jointly and severally agree to
indemnify and hold harmless each Bank, and reimburse such Bank upon its written
request, for the amount of any Taxes so levied or imposed and paid by such Bank.

defined in Section 7701(a)(30) of the Code) agrees to deliver to the Borrower
and the Agent on or prior to the Effective Date, or in the case of a Bank that

(financial or otherwise) or prospects of Holdings and its Subsidiaries taken as
a whole.

(or participate in) the Letters of Credit as provided herein, each of Holdings
and the Borrower makes the following representations, warranties and agreements
as to itself and as to each of its Subsidiaries, as of the Initial Borrowing
Date (both before and after giving effect to the Credit Events occurring on such
date, the Transaction and the other transactions contem plated by the Documents,
and all references to Holdings and the Borrower herein and elsewhere in this
Agreement, shall, unless otherwise specifically indicated, be references to
Holdings and the Borrower after giving effect to the Transaction) and as of the

true and correct on and as of the Initial Borrowing Date and on the date of each
such Credit Event:

the aggregate, could not reasonably be expected to have a material adverse
effect on the performance, business, assets, nature of assets, liabilities,
operations, properties, condition (financial or otherwise) or prospects of
Holdings and its Subsidiaries taken as a whole.

          7.02  Corporate Power and Authority.  Each of Holdings and its

Documents constitutes its legal, valid and binding obligation enforceable in
accordance with its terms, except as the enforceability thereof may be limited
by bankruptcy, reorganization, moratorium or similar laws relating to or
limiting creditors'

rights generally or by general equitable principles (regardless of whether the
issue of enforceability is considered in a proceeding in equity or at law).

          7.03  No Violation.  Neither the execution, delivery or performance by
                ------------

compliance by it with the terms and provisions thereof, (i) will contravene any
provision of any applicable law, statute, rule or regulation or any order,
writ, injunction or decree of any court or governmental instrumentality, (ii)
will conflict with or result in any breach of any of the terms, covenants,
conditions or provisions of, or constitute a default under, or result in the
creation or imposition of (or the obligation to create or impose) any Lien

of Holdings or any of its Subsidiaries pursuant to the terms of any indenture,
mortgage, deed of trust, credit agreement or loan agreement, or any other
agreement, contract or instrument to which Holdings or its Subsidiaries is a
party or by which it or any of its property or assets is bound or to which it
may be subject or (iii) will violate any provision of the Certificate of
Incorporation or By-Laws (or similar organizational documents) of Holdings or
any of its Subsidiaries.

          7.04  Governmental Approvals.  No order, consent, approval, license,

Liabilities; Projections; etc.  (a)  (i) The audited consolidated balance sheets
- ------------------------------                                                  
of Holdings for the fiscal years ended December 31, 1995 and December 31, 1996
and the audited consolidated balance sheet of Holdings at June 30, 1997 and the
related consolidated statements of operations and cash flows of Holdings for the
fiscal year or six month period, as the case may be, ended as of such dates, and
the financial statements of each Company listed on Schedule III at the dates
listed on Schedule III and for the fiscal periods ended as of the dates listed
on Schedule III, which, in the case of the annual statements, have been audited
by Arthur Andersen L.L.P., in the case of the financial statements of Holdings
and have been examined or reviewed by the independent certified public
accountants listed on Schedule III, in the case of the other financial
statements, who delivered unqualified opinions in respect thereto and (ii) the
pro forma (after giving effect to the Transaction and the related financing
thereof) consolidated balance sheet of Holdings as at the Initial Borrowing
Date, copies of all of which financial statements referred to in the preceding
clauses (i) and (ii) have heretofore been furnished to the Agent, present fairly
the financial position of the respective entities at the dates of said
statements and the results of operations for the period covered thereby (or, in
the case of the pro forma balance sheet, present a

                                      -47-
<PAGE>
 
good faith estimate of the pro forma financial condition of Holdings and its
Subsidiaries (after giving effect to the Transaction) on a consolidated basis at
the date thereof).  All such financial statements have been prepared in
accordance with generally accepted accounting principles and practices
consistently applied except to the extent provided in the notes to said
financial statements and with respect to interim financial statements, subject
to normal year end adjustments.  Since June 30, 1997, there has been no material
adverse change in the performance, business, assets, nature of assets,
liabilities, operations, properties, condition (financial or otherwise) or
prospects of Holdings and its Subsidiaries taken as a whole.

          (b)  On and as of the Initial Borrowing Date, on a pro forma basis
after giving effect to the Transaction and all other transactions contemplated
by the Documents as of such date and to all Indebtedness (including, without
limitation, the Loans) being incurred in connection with the Transaction, and
Liens created, and to be created, by each Credit Party in connection therewith:
(a) the sum of the assets (including all contribution and subrogation rights and
other intangible assets), at a fair valuation, of each Credit Party will exceed
its debts; (b) no Credit Party has incurred or intends to, or believes that it
will, incur debts beyond its ability to pay such debts as such debts mature; and
(c) each Credit Party will have sufficient capital with which to conduct its
business.  For purposes of this Section 7.05(b) "debt" means any liability on a
claim, and "claim" means (i) right to payment, whether or not such a right is
reduced to judgment, liquidated, unliquidated, fixed, contingent, matured,
unmatured, disputed, undisputed, legal, equitable, secured, or unsecured or
(ii) right to an equitable remedy for breach of performance if such breach gives
rise to a payment, whether or not such right to an equitable remedy is reduced
to judgment, fixed, contingent, matured, unmatured, subordinated, disputed,
undisputed, secured or unsecured.

          (c)  Except as fully reflected in the financial statements and the
notes related thereto described in Section 7.05(a), there were as of the Initial
Borrowing Date (and after giving effect to the Transaction and the other
transactions contemplated hereby and by the Documents) no liabilities or
obligations with respect to Holdings or any of its Subsidiaries of any nature
whatsoever (whether absolute, accrued, contingent or otherwise and whether or
not due) which, either individually or in aggregate, could reasonably be
expected to be material to Holdings and its Subsidiaries taken as a whole.  As
of the Initial Borrowing Date, neither Holdings nor any of its Subsidiaries
knows of any basis for the assertion against Holdings or any of its Subsidiaries
of any liability or obligation of any nature whatsoever that is not fully
reflected in the financial statements and the notes related thereto described in
Section 7.05(a) which, either individually or in the aggregate, could reasonably
be expected to be material to Holdings and its Subsidiaries taken as a whole.
As of the Initial Borrowing Date (and after giving effect to the Transaction)
none of Holdings or any of its Subsidiaries will have any outstanding
Indebtedness or preferred stock other than (i)

                                      -48-
<PAGE>
 
the Loans, (ii) the Existing Indebtedness, (iii) the Senior Subordinated Notes
and (iv) Holdings Preferred Stock set forth on Schedule VII.

          (d)  On and as of the Initial Borrowing Date, the Projections have
been prepared in good faith by Holdings and there are no statements or
conclusions in any of the Projections which are based upon or include
information known to Holdings or the Borrower to be misleading or which fail to
take into account material information regarding the matters reported therein.
On the Initial Borrowing Date, each of Holdings and the Borrower believes that
the Projections were reasonable and attainable (although actual results may
differ from the Projections and no representation is made that the Projections
will in fact be attained).

          7.06  Litigation.  There are no actions, suits or proceedings pending
                ----------                                                     
or, to the best knowledge of Holdings, threatened (i) with respect to any
Document, or (ii) that are reasonably likely to materially and adversely affect
the performance, business, assets, nature of assets, liabilities, operations,
properties, condition (financial or otherwise) or prospects of Holdings and its
Subsidiaries taken as a whole.

          7.07  True and Complete Disclosure.  All factual information (taken as
                ----------------------------                                    
a whole) heretofore or contemporaneously furnished by or on behalf of Holdings
or any Subsidiary of Holdings in writing to any Bank (including, without
limitation, all information contained in the Documents) for purposes of or in
connection with this Agreement or any transaction contemplated herein is, and
all other such factual information (taken as a whole with all information
previously furnished) hereafter furnished by or on behalf of Holdings or any
Subsidiary of Holdings in writing to any Bank will be, true and accurate in all
material respects on the date as of which such information is dated or
certified and not incomplete by omitting to state any material fact.

          7.08  Use of Proceeds; Margin Regulations.  (a)  All proceeds of the
                -----------------------------------                           
Term Loans incurred on the Initial Borrowing Date shall be used to finance, in
part, the Purchase Price of the Contemporaneous Acquisitions, directly or
indirectly to repay the Indebtedness of the Companies incurred to finance the
Pre-Closing Acquisitions and to pay Transaction Fees and Expenses.  All proceeds
of the Term Loans incurred on a DVI Payment Date shall be used to repay DVI
Indebtedness.  In addition, proceeds of the Term Loans incurred on the Initial
Borrowing Date in excess of the amounts used in accordance with the first
sentence of this Section 7.08 shall be deposited in the Cash Collateral Account
to be utilized solely to pay the Purchase Price and closing costs with respect
to the Post-Closing Acquisitions or other acquisitions approved by the Required
Banks or to pay amounts owing pursuant to the DVI Revolver in accordance with
the terms of the Cash Collateral Agreement.

                                      -49-
<PAGE>
 
          (b)  All proceeds of Revolving Loans and Swingline Loans shall be used
by the Borrower for general corporate and working capital purposes of the
Borrower and its Subsidiaries but shall not be permitted to be used to effect
Permitted Acquisitions.

          (c)  All proceeds of Acquisition Loans shall be used by the Borrower
only to effect Permitted Acquisitions and to pay fees, costs and expenses
related to such acquisitions; provided, however, proceeds of Acquisition Loans
may be dividended by the Borrower to Holdings to be used by Holdings to effect
Permitted Acquisitions.

          (d)  No part of the proceeds of any Loan will be used to purchase or
carry any Margin Stock or to extend credit for the purpose of purchasing or
carrying any Margin Stock.  Neither the making of any Loan nor the use of the
proceeds thereof nor the occurrence of any other Credit Event will violate or
be inconsistent with the provisions of Regulation G, T, U or X of the Board of
Governors of the Federal Reserve System.

          7.09  Tax Returns and Payments.  Each of Holdings and its Subsidiaries
                ------------------------                                        
has timely filed or caused to be timely filed (including pursuant to any valid
extensions of time for filing) with the appropriate taxing authority, all
material returns, statements, forms and reports for taxes (the "Returns")
required to be filed by or with respect to the income, properties or operations
of Holdings and/or any of its Subsidiaries.  The Returns accurately reflect in
all material respects all liability for taxes of Holdings and its Subsidiaries
as a whole for the periods covered thereby.  Each of Holdings and its
Subsidiaries have paid all material taxes payable by them which have become due
other than those contested in good faith and for which adequate reserves have
been established in accordance with generally accepted accounting principles.
There is no material action, suit, proceeding, investigation, audit, or claim
now pending or, to the best knowledge of Holdings or any of its Subsidiaries,
threatened by any authority regarding any taxes relating to Holdings or any of
its Subsidiaries.  As of the Initial Borrowing Date, neither Holdings nor any of
its Subsidiaries has entered into an agreement or waiver or been requested to
enter into an agreement or waiver extending any statute of limitations relating
to the payment or collection of taxes of Holdings or any of its Subsidiaries, or
is aware of any circumstances that would cause the taxable years or other
taxable periods of Holdings or any of its Subsidiaries not to be subject to the
normally applicable statute of limitations.  Neither Holdings nor any of its
Subsidiaries has provided, with respect to themselves or property held by them,
any consent under Section 341 of the Code.  None of Holdings or any of its
Subsidiaries has incurred, or will incur, any material tax liability in
connection with the Transaction or any other transactions contemplated hereby
(it being understood that the representation contained in this sentence does not
cover any future tax liabilities of Holdings or any of its Subsidiaries arising
as a result of the operation of their businesses in the ordinary course of
business).

     pursuant to the Securities Purchase Agreement and such other information
     related to the Person or business, division or product line being acquired

               (vi) calculations are made by the Borrower of the Consolidated
     EBITDA of the Person or business, division or product line being acquired
     pursuant to the respective Permitted Acquisition (determined in accordance
     with the definition of Consolidated EBITDA contained herein, but treating
     references therein and in any other defined terms used in determining
     Consolidated EBITDA to "Holdings" to instead be references to the Person or
     business, division or product line being acquired pursuant to the
     respective Permitted Acquisition), and the amount thereof shall exceed zero
     for the period of four consecutive fiscal quarters (taken as one accounting
     period) most recently ended prior to the date of the Permitted Acquisition
     (the "Calculation Period"); provided, however, in the case of calculations
                                 --------  -------                              
     based on financial statements not audited by a "big-six accounting firm" or
     other nationally recognized accounting firm reasonably acceptable to the
     Agent, the Agent and the Required Banks shall be satisfied that the
     Consolidated EBITDA of such Person or business, division or product line
     being acquired pursuant to the respective Permitted Acquisition exceeds
     zero for the Calculation Period;

                                      -68-
<PAGE>
 
               (vii)  the Agent shall be satisfied in its reasonable discretion
     that the proposed Permitted Acquisition will not be reasonably likely to
     result in materially increased liabilities (contingent or otherwise) of
     Holdings or any of its Subsidiaries other than Permitted Seller Notes and
     Permitted Earn-Out Debt incurred in accordance with the provisions of this
     Agreement (including, without limitation, tax, ERISA or environmental
     liabilities);
                                                                              
     provided that, so long as the Permitted Acquisition Notice has been given
     --------                                                                 
     as required above and so long as Holdings has furnished each Bank,
     following request by the Agent, information with respect to liabilities of
     the type described in this clause with all information so requested, if the
     Agent has not notified the Borrower on or prior to the tenth day prior to
     the consummation of the Permitted Acquisition that Agent has not yet been
     satisfied that the proposed Permitted Acquisition would not be reasonably
     likely to result in materially increased liabilities of the Borrower or any
     of its Subsidiaries, such Bank shall be deemed for purposes of this clause
     (vii) to be so satisfied;

               (viii) in the case of both Permitted Acquisitions and repayment
     of DVI Indebtedness, after giving effect to any additional indebtedness to
     be incurred in connection therewith and, in the case of Permitted
     Acquisitions only, the Consolidated EBITDA of the Person or business,
     division or product line being acquired pursuant to the respective
     Permitted Acquisition determined in accordance with clause 8.15(a)(vi)
     above for the Calculation Period, (I) the ratio of Consolidated
     Indebtedness on the last day of the Calculation Period to Consolidated
     EBITDA of Holdings and its Subsidiaries for the Calculation Period, on a
     Pro Forma Basis shall be equal to or less than 3.50:1 and (II) the ratio of
     Consolidated Senior Indebtedness on the last day of the Calculation Period
     to Consolidated EBITDA of Holdings and its Subsidiaries for the Calculation
     Period, on a Pro Forma Basis shall be equal to or less than the lesser of
     2.50:1;

               (ix)   in the case of both Permitted Acquisitions and repayment
     of DVI Indebtedness, recalculations are made by the Borrower of compliance
     with the covenants contained in Sections 9.09 through 9.13, inclusive, for
     the Calculation Period in a Pro Forma Basis, and such recalculations shall
     show that all such covenants would have been complied with throughout the
     Calculation Period on a Pro Forma Basis;

               (x)    in the case of both Permitted Acquisitions and repayment
     of DVI Indebtedness, the Borrower in good faith believes, on a Pro Forma
     Basis (as if the Calculation Period were the one-year period following the
     date of the consummation of the respective Permitted Acquisition) that the
     financial covenants contained in such Sections 9.09 through 9.13,
     inclusive, will continue to be met for the one year period following the
     date of the consummation of the respective Permitted Acquisition;

                                      -69-
<PAGE>
 
               (xi)    in the case of a repayment of the DVI Indebtedness, the
     consent of the Required Banks shall have been obtained; provided, however,
                                                             --------  -------
     this restriction shall not prevent any mandatory payments on the DVI
     Indebtedness from sources other than Term Loans;

               (xii)   in the case of Permitted Acquisitions, the purchase price
     for any Permitted Acquisition may not exceed ten times the Consolidated
     EBITDA of the Person or business, division or product line being acquired
     for the Calculation Period;

               (xiii)  in the case of Permitted Acquisitions, the Borrower shall
     not draw more than $2 million from the Acquisition Loan Facility to be used
     to purchase any one Person or business, division or product line;

               (xiv)   in the case of Permitted Acquisitions, the sum of the
     items described in clauses (I) - (IV) of Section 8.15(a)(v) in connection
     with each Permitted Acquisition shall not exceed $5 million;

               (xv)    with respect to the Permitted Acquisitions effected
     during a twelve month period, the Borrower shall not draw more than $7
     million from the Acquisition Loan Facility during any twelve month period;

               (xvi)   the aggregate amount (determined by using the face amount
     of the debt or the amount payable at maturity, whichever is greater) of
     Permitted Seller Notes and Permitted Earn-Out Debt issued by Holdings after
     the date hereof shall not exceed $19.5 million and (A) such Indebtedness
     shall have an average maximum current pay interest of no more than 8% per
     annum, with no single item of Indebtedness bearing interest at a rate
     greater than 10% per annum, (B) no single item of Indebtedness shall have a
     final maturity of less than two years and (C) all such Indebtedness shall
     have an average weighted-life to maturity of not less than 2.5 years.

               (xvii)  in the case of Permitted Acquisitions, the Borrower shall
     only include for any Person or business, division or product line acquired,
     100% of audited financial statement based Consolidated EBITDA calculated on
     a Pro Forma Basis and 75% of personally guaranteed unaudited financial
     statement based Consolidated EBITDA calculated on a Pro Forma Basis with
     respect to calculation made in connection with the covenants contained in
     this Section 8.15 and Sections 9.09 through 9.13, inclusive; and

               (xviii) prior to the consummation of the respective Permitted
     Acquisition or repayment of DVI Indebtedness, as the case may be, the
     Borrower shall furnish

                                      -70-
<PAGE>
 
     the Agent and the Banks an officer's certificate executed by the chief
     financial officer of Holdings, certifying as to compliance with the
     requirements of the applicable preceding clauses (i) through (xvii) and
     containing the calculations required by preceding clauses (v), (vi),
     (viii), (ix), (xii), (xiv), (xv) and (xvi).  The consummation of each
     Permitted Acquisition or the repayment of the DVI Indebtedness, as the case
     may be, shall be deemed to be a representation and warranty by Holdings
     that all conditions thereto have been satisfied and that same is permitted
     in accordance with the terms of this Agreement, which representation and
     warranty shall be deemed to be a representation and warranty for all
     purposes hereunder, including, without limitation, Sections 6 and 10;

          (b)  At the time of each Permitted Acquisition involving the creation
or acquisition of a Subsidiary, not less than 100% of the capital stock of such
Subsidiary shall be directly owned by the Borrower and such 100% owned by the
Borrower shall be pledged for the benefit of the Secured Creditors pursuant to
the Pledge Agreement or pursuant to a similar agreement satisfactory to the
Agent; provided, however, for up to three (3) Business Day after such Permitted
       --------  -------                                                       
Acquisition, Holdings may own such Subsidiary.

          (c)  The Borrower shall cause each Subsidiary which is formed to
effect, or is acquired pursuant to, a Permitted Acquisition to execute and
deliver, prior to the date of the respective Permitted Acquisition, the
Subsidiaries Guaranty (or by an amendment thereto pursuant to which it shall be
a party thereto) or a substantially similar guaranty, in either case with the
documentation to be in form and substance satisfactory to the Agent.

          (d)  The Borrower shall on the date of a Permitted Acquisition cause
the respective Subsidiary of the Borrower to, grant to the Collateral Agent, for
the benefit of the Secured Creditors, first priority perfected security
interests in all property of the Borrower or such Subsidiaries (whether real,
personal or otherwise) acquired in connection with the Permitted Acquisition and
to take, or cause such Subsidiary to take, all actions requested by the Agent or
the Required Banks (including, without limitation, the obtaining of UCC-11's,
the filing of UCC-1's and the obtaining of mortgage policies, title surveys and
real estate appraisals) in connection with the granting of such security
interests.  All security interests required to be granted pursuant to this
Section 8.15(d) shall be granted pursuant to such security documentation (which
shall be substantially similar to the analogous Security Documents already
executed and satisfactory in form and substance to the Agent) and shall (except
as otherwise consented to by the Agent and the Required Banks) constitute valid
and enforceable perfected security interests prior to the rights of all third
Persons and subject to no other Liens except Permitted Liens.  The security
documents and other instruments related thereto shall be duly recorded or filed
in such manner and in such places as are required by law to establish, perfect,
preserve and protect the Liens, in favor of the Collateral Agent for the benefit
of the Secured Creditors, required to be granted pursuant to the respective
Additional Security Documents and all taxes, fees

                                      -71-

and other charges payable in connection therewith shall be paid in full by the
Borrower.  At the time of the execution and delivery of Additional Security
Documents, the Borrower shall cause to be delivered to the Collateral Agent such
opinions of counsel, mortgage policies, environmental appraisals, surveys and
other related documents as may be reasonably requested by the Collateral Agent
or the Required Banks to assure themselves that this Section has been complied
with.  All actions required to be taken by this Section 8.15(d) with respect to
the Additional Collateral shall be completed no later than the date on which the
Permitted Acquisition is effected.

          8.16  Registry.  The Borrower hereby designates the Agent to serve as
                --------                                                       
the Borrower's agent, solely for purposes of this Section 8.16, to maintain a
register (the "Register") on which it will record the Commitments from time to
time of each of the Banks, the Loans made by each of the Banks and each
repayment in respect of the principal amount of the Loans of each Bank.  Failure
to make any such recordation, or any error in such recordation shall not affect
the Borrower's obligations in respect of such Loans.  With respect to any Bank,
the transfer of the Commitments of such Bank and the rights to the principal of,
and interest on, any Loan made pursuant to such Commitments shall not be
effective until such transfer is recorded on the Register maintained by the
Agent with respect to ownership of such Commitments and Loans and prior to such
recordation all amounts owing to the transferor with respect to such Commitments
and Loans shall remain owing to the transferor.  The registration of an
assignment or transfer of all or part of any Commitments and Loans shall be
recorded by the Agent on the Register only upon the acceptance by the Agent of a
properly executed and delivered assignment and assumption agreement pursuant to
Section 14.04(b).  Coincident with the delivery of such an assignment and
assumption agreement to the Agent for acceptance and registration of assignment
or transfer of all or part of a Loan, or as soon thereafter as practicable, the
assigning or transferor Bank shall surrender the Note evidencing such Loan, and
thereupon one or more new Notes in the same aggregate principal amount shall be
issued to the assigning or transferor Bank and/or the new Bank.  The Borrower
agrees to indemnify the Agent from and against any and all losses, claims,
damages and liabilities of whatsoever nature which may be imposed on, asserted
against or incurred by the Agent in performing its duties under this Section
8.16.

          8.17  Further Actions.  (a)  Each Credit Party shall grant to the
                ---------------                                            
Collateral Agent, for the benefit of the Secured Creditors, at the request of
the Agent or the Required Banks, at any time, a security interest in any Real
Property or vehicles owned by any such Credit Party and any other assets of such
Credit Party not already subject to a Mortgage or other Security Document.  Each
Credit Party shall take all actions requested by the Agent or the Required Banks
(including, without limitation, the obtaining of mortgage policies, title
surveys and real estate appraisals satisfying the requirements of all applicable
laws) in connection with the granting of such security interests; provided,
                                                                  -------- 
however, in no event shall the Agent or the Required Banks request a security
- -------                                                                      
interest in any Leaseholds

                                      -72-
<PAGE>
 
unless the Agent or the Required Banks has reasonably determined that such
Leasehold has material value.

          (b)  The security interests required to be granted pursuant to clause
(a) above shall be granted pursuant to mortgages, deeds of trust and security
agreements, in each case satisfactory in form and substance to the Agent and the
Required Banks, which mortgages and security agreements shall create valid and
enforceable perfected security interests prior to the rights of all third
Persons and subject to no other Liens except Permitted Liens.  The mortgages and
other instruments related thereto and security agreements shall be duly recorded
or filed in such manner and in such places and at such times as are required by
law to establish, perfect, preserve and protect the Liens, in favor of the
Collateral Agent for the benefit of the Secured Creditors, required to be
granted pursuant to such documents and all taxes, fees and other charges payable
in connection therewith shall be paid in full by the Borrower.  At the time of
the execution and delivery of the additional documents, the Borrower shall cause
to be delivered to the Collateral Agent such opinions of counsel, mortgage
policies, title surveys, real estate appraisals, certificates of title and other
related documents as may be reasonably requested by the Agent or the Required
Banks to assure themselves that this Section 8.17 has been complied with.

          (c)  Each Credit Party agrees that each action required by Section
8.17(a), or (b) shall be completed within 60 days of the date such action is
requested to be taken.

and the Concentration Account Bank, acknowledging that the Concentration Account
listed on a notice sent by Holdings or any of its Subsidiaries to the Collateral
Agent at the time of creation of such account maintained at the Concentration

and that all moneys, instruments and other securities deposited in such
Concentration Account are to be held by the Concentration Account Bank for the
benefit of the Collateral Agent subject to the right of the account parties to
utilize such deposited amounts in accordance with the Concentration Deposit
Account Consent Letter.  Each of Holdings and its Subsidiaries represents and
warrants that it does not now maintain, and will not in the future maintain, any
other Concentration Account with any Concentration Account Bank other than the
applicable Concentration Account; provided, however, that Holdings and its
                                  --------  -------                       
Subsidiaries shall be permitted to establish new Concentration Accounts pursuant
to the terms of the Security Agreement.

                ----------------------                                        
will take all such action as is necessary to keep the operations of each such
Person separate and apart from those of each such other Person, including,
without limitation, ensuring that all customary corporate formalities, including

                 -----------                                               
Agent (for purposes of this Section 12, the term "Agent" shall include Banque
Paribas in its capacity as Collateral Agent pursuant to the Security Documents)
to act as specified herein and in the other Credit Documents.  Each Bank hereby
irrevocably authorizes, and each holder of any Note by the acceptance of such
Note shall be deemed irrevocably to authorize, the Agent to take such action on
its behalf under the provisions of this Agreement, the

                                     -120-

other Credit Documents and any other instruments and agreements referred to
herein or therein and to exercise such powers and to perform such duties
hereunder and thereunder as are specifically delegated to or required of the
Agent by the terms hereof and thereof and such other powers as are reasonably
incidental thereto.  The Agent may perform any of its duties hereunder by or
through its officers, directors, agents or employees.

          12.02  Nature of Duties.  The Agent shall have no duties or
                 ----------------

Security Documents.  Neither the Agent nor any of its officers, directors,
agents or employees shall be liable for any action taken or omitted by it or
them hereunder or under any other Credit Document or in connection herewith or
therewith, unless caused by its or their gross negligence or willful misconduct.
The duties of the Agent shall be mechanical and administrative in nature; the
Agent shall not have by reason of this Agreement or any other Credit Document a
fiduciary relationship in respect of any Bank or the holder of any Note; and
nothing in this Agreement or any other Credit Document, expressed or implied,
is intended to or shall be so construed as to impose upon the Agent any
obligations in respect of this Agreement or any other Credit Document except as
expressly set forth herein.

          12.03  Lack of Reliance on the Agent.  Independently and without
                 -----------------------------                            
reliance upon the Agent, each Bank and the holder of each Note, to the extent it
deems appropriate, has made and shall continue to make (i) its own independent
investigation of the financial condition and affairs of Holdings and its
Subsidiaries in connection with the making and the continuance of the Loans and
the participation in Letters of Credit and the taking or not taking of any
action in connection herewith and (ii) its own appraisal of the creditworthiness
of Holdings and its Subsidiaries and, except as expressly provided in this
Agreement, the Agent shall have no duty or responsibility, either initially or
on a continuing basis, to provide any Bank or the holder of any Note with any
credit or other information with respect thereto, whether coming into its
possession before the making of the Loans, the participation in the Letters of
Credit or at any time or times thereafter.  The Agent shall not be responsible
to any Bank or the holder of any Note for any recitals, statements, information,
representations or warranties herein or in any document, certificate or other
writing delivered in connection herewith or for the execution, effectiveness,
genuineness, validity, enforceability, perfection, priority or sufficiency of
this Agreement or any other Credit Document or the financial condition of
Holdings or its Subsidiaries or be required to make any inquiry concerning
either the performance or observance of any of the terms, provisions or
conditions of this Agreement or any other Credit Document, or the financial
condition of Holdings or its Subsidiaries or the existence or possible existence
of any Default or Event of Default.  In no event shall the Agent be required in
contravention of applicable law or if such action would cause it, in its sole
determination, to incur any risk or liability for which it is not adequately
indemnified for to its satisfaction.

instructions from the Required Banks with respect to any act or action
(including failure to act) in connection with this Agreement or any other Credit
Document, the Agent shall be entitled to refrain from such act or taking such
action unless and until the Agent shall have received instructions from the
Required Banks; and the Agent shall not incur liability to any Person by reason
of so refraining. Without limiting the foregoing, no Bank or the holder of any
Note shall have any right of action whatsoever against the Agent as a result of
the Agent acting or refraining from acting hereunder or under any other Credit
Document in accordance with the instructions of the Required Banks.

          12.05  Reliance.  The Agent shall be entitled to rely, and shall be
                 --------                                                    
fully protected in relying, upon any note, writing, resolution, notice,
statement, certificate, telex, teletype or facsimile message, cablegram,
radiogram, legal opinion, order or other document or telephone message signed,
sent or made by any Person that the Agent believed to be the proper Person, and,
with respect to all legal matters pertaining to this Agreement and any other
Credit Document and its duties hereunder and thereunder, upon advice of counsel
selected by it.

          12.06  Indemnification.  (a)  To the extent the Agent is not
                 ---------------                                      
reimbursed and indemnified by the Borrower, the Banks will reimburse and

determining the Required Banks, for and against any and all liabilities,
obligations, losses, damages, penalties, claims, actions, judgments, suits,
costs, expenses or disbursements of whatsoever kind or nature which may be
imposed on, asserted against or incurred by the Agent in performing its duties
hereunder or under any other Credit Document, in any way relating to or arising
out of this Agreement or any other Credit Document; provided that no Bank shall
                                                    --------                   
be liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the Agent's gross negligence or willful misconduct.

          (b)  The Agent shall be fully justified in failing or refusing to take
any action hereunder and under any other Credit Document (except actions
expressly required to be taken by it hereunder or under the Credit Documents)
unless it shall first be indemnified to its satisfaction by the Banks pro rata
                                                                      --- ----
against any and all liability, cost and expense that it may incur by reason of
taking or continuing to take any such action.

          12.07  The Agent in Its Individual Capacity.  With respect to its
                 ------------------------------------                      
obligation to make Loans under this Agreement, the Agent shall have the rights
and powers specified herein for a "Bank" and may exercise the same rights and
powers as though it were not performing the duties specified herein; and the
term "Banks," "Required Banks," "holders of Notes" or any similar terms shall,
unless the context clearly otherwise indicates, include the Agent in its
individual capacity.  The Agent may accept deposits from, lend money to,

                                     -122-

Credit Party or any Affiliate of any Credit Party as if it were not performing
the duties specified herein, may hold equity interests in the Borrower or any of
its Affiliates and may accept fees and other consideration from the Borrower or
any other Credit Party for services in connection with this Agreement and
otherwise without having any liability to, and without having to account for the
same to, the Banks.

          12.08  Holders.  The Agent may deem and treat the payee of any Note as
                 -------                                                        
the owner thereof for all purposes hereof unless and until a written notice of
the assignment, transfer or endorsement thereof, as the case may be, shall have
been filed with the Agent.  Any request, authority or consent of any Person who,
at the time of making such request or giving such authority or consent, is the
holder of any Note shall be conclusive and binding on any subsequent holder,
transferee, assignee or indorsee, as the case may be, of such Note or of any
Note or Notes issued in exchange therefor.

          12.09  Resignation by the Agent.  (a)  The Agent may resign from the
                 ------------------------                                     
performance of all its functions and duties hereunder and/or under the other
Credit Documents at any time by giving 15 Business Days' prior written notice to
the Borrower and the Banks.  Such resignation shall take effect upon the
appointment of a successor Agent pursuant to clauses (b) and (c) below or as
otherwise provided below.

          (b)  Upon any such notice of resignation, the Required Banks shall
appoint a successor Agent hereunder or thereunder who shall be a commercial bank
or trust company reasonably acceptable to the Borrower.

          (c)  If a successor Agent shall not have been so appointed within such
15 Business Day period, the Agent, with the consent of the Borrower, shall then
appoint a successor Agent who shall serve as Agent hereunder or thereunder
until such time, if any, as the Banks appoint a successor Agent as provided
above.

          (d)  If no successor Agent has been appointed pursuant to clause (b)
or (c) above by the 30th Business Day after the date such notice of resignation
was given by the Agent, the Agent's resignation shall become effective and the

successor Agent as provided above.


          Section 13.  Guaranty.
                       -------- 

          13.01  The Guaranty.  In order to induce the Banks to enter into this
                 ------------

issuance of the Letters of

                                     -123-

Credit, Holdings hereby agrees with the Banks as follows:  Holdings hereby
unconditionally and irrevocably guarantees as primary obligor and not merely as
surety the full and prompt payment when due, whether upon maturity, by
acceleration or otherwise, of any and all indebtedness of the Borrower to the
Banks under this Agreement and the other Credit Documents and under each
Interest Rate Protection or Other Hedging Agreement entered into by a Bank or an
affiliate of a Bank with the Borrower.  If any or all of the indebtedness of the
Borrower to the Banks becomes due and payable hereunder or under such other
Credit Documents or Interest Rate Protection or Other Hedging Agreements,
Holdings unconditionally promises to pay such indebtedness to the Banks, or
order, on demand, together with any and all expenses which may be incurred by
the Agent or the Banks in collecting any of the indebtedness.  The word
"indebtedness" is used in this Section 13 in its most comprehensive sense and
means any and all advances, debts, obligations and liabilities of the Borrower
arising in connection with this Agreement or any other Credit Documents or under
any Interest Rate Protection or Other Hedging Agreement with a Bank or an
affiliate of the Bank, in each case, heretofore, now, or hereafter made,
incurred or created, whether voluntarily or involuntarily, absolute or
contingent, liquidated or unliquidated, determined or undetermined, whether or
not such indebtedness is from time to time reduced, or extinguished and
thereafter increased or incurred, whether the Borrower may be liable
individually or jointly with others, whether or not recovery upon such
indebtedness may be or hereafter become barred by any statute of limitations,
and whether or not such indebtedness may be or hereafter become otherwise
unenforceable.

          13.02  Bankruptcy.  Additionally, Holdings unconditionally and
                 ----------                                             
irrevocably guarantees the payment of any and all indebtedness of the Borrower
to the Banks whether or not due or payable by the Borrower upon the occurrence
of any of the events specified in Section 10.05, and unconditionally and
irrevocably promises to pay such indebtedness to the Banks, or order, on demand,
in lawful money of the United States.

          13.03  Nature of Liability.  The liability of Holdings hereunder is
                 -------------------                                         
exclusive and independent of any security for or other guaranty of the
indebtedness of the Borrower whether executed by Holdings, any other guarantor
or by any other party, and the liability of Holdings hereunder shall not be
affected or impaired by (a) any direction as to application of payment by the
Borrower or by any other party, or (b) any other continuing or other guaranty,
undertaking or maximum liability of a guarantor or of any other party as to the
indebtedness of the Borrower, or (c) any payment on or in reduction of any such
other guaranty or undertaking, or (d) any dissolution, termination or increase,
decrease or change in personnel by the Borrower, or (e) any payment made to the
Agent or the Banks on the indebtedness which the Agent or such Banks repay the
Borrower pursuant to court order in any bankruptcy, reorganization, arrangement,
moratorium or other debtor relief proceeding, and Holdings waives any right to
the deferral or modification of its obligations hereunder by reason of any such
proceeding.

          13.04  Guaranty Absolute.  No invalidity, irregularity or
                 -----------------                                 
unenforceability of all or any part of the indebtedness guaranteed hereby or of
any security therefor shall affect, impair or be a defense to this Guaranty, and
this Guaranty shall be primary, absolute and unconditional notwithstanding the
occurrence of any event or the existence of any other circumstances which might
constitute a legal or equitable discharge of a surety or guarantor except
payment in full of the indebtedness guaranteed herein.

          13.05  Independent Obligation.  The obligations of Holdings hereunder
                 ----------------------                                        
are independent of the obligations of any other guarantor or the Borrower, and a
separate action or actions may be brought and prosecuted against Holdings
whether or not action is brought against any other guarantor or the Borrower and
whether or not any other guarantor or the Borrower be joined in any such action
or actions.  Holdings waives, to the fullest extent permitted by law, the
benefit of any statue of limitations affecting its liability hereunder or the
enforcement thereof.  Any payment by the Borrower or other circumstance which
operates to toll any statute of limitations as to the Borrower shall operate to
toll the statute of limitations as to Holdings.

          13.06  Authorization.  Holdings authorizes the Agent and the Banks
                 -------------                                              
without notice or demand to Holdings, and without affecting or impairing its
liability hereunder, from time to time to:

          (a)  change the manner, place or terms of payment of, and/or change or
     extend the time of payment of, renew, increase, accelerate or alter, any of
     the indebtedness (including any increase or decrease in the rate of
     interest thereon), any security therefor, or any liability incurred
     directly or indirectly in respect thereof, and the Guaranty herein made
     shall apply to the indebtedness as so changed, extended, renewed or
     altered;

          (b)  take and hold security for the payment of the indebtedness and
     sell, exchange, release, surrender, realize upon or otherwise deal with in
     any manner and in any order any property by whomsoever at any time pledged
     or mortgaged to secure, or howsoever securing, the indebtedness or any
     liabilities (including any of those hereunder) incurred directly or
     indirectly in respect thereof or hereof, and/or any offset thereagainst;

          (c)  exercise or refrain from exercising any rights against the
     Borrower or others or otherwise act or refrain from acting;

          (d)  release or substitute any one or more endorsers, guarantors, the
     Borrower or other obligors;

                                     -125-
<PAGE>
 
          (e)  settle or compromise any of the indebtedness, any security
     therefor or any liability (including any of those hereunder) incurred
     directly or indirectly in respect thereof or hereof, and may subordinate
     the payment of all or any part thereof to the payment of any liability
     (whether due or not) of the Borrower to its creditors other than the Banks;

          (f)  apply any sums by whomsoever paid or howsoever realized to any
     liability or liabilities of the Borrower to the Banks regardless of what
     liability or liabilities of Holdings or the Borrower remain unpaid;

          (g)  consent to or waive any breach of, or any act, omission or
     default under, this Agreement or any of the instruments or agreements
     referred to herein, or otherwise amend, modify or supplement this Agreement
     or any of such other instruments or agreements; and/or

          (h)  take any other action which would, under otherwise applicable
     principles of common law, give rise to a legal or equitable discharge of
     Holdings from its liabilities under this Section 13.

          13.07  Reliance.  It is not necessary for the Agent or the Banks to
                 --------                                                    
inquire into the capacity or powers of the Borrower or its Subsidiaries or the
officers, directors, partners or agents acting or purporting to act on its
behalf, and any indebtedness made or created in reliance upon the professed
exercise of such powers shall be guaranteed hereunder.

          13.08  Subordination.  Any indebtedness of the Borrower now or
                 -------------                                          
hereafter held by Holdings is hereby subordinated to the indebtedness of the
Borrower to the Agent and the Banks; and such indebtedness of the Borrower to
Holdings, if the Agent (at the direction of the Required Banks), after an Event
of Default has occurred, so requests, shall be collected, enforced and received
by Holdings as trustee for the Banks and be paid over to the Banks on account of
the indebtedness of the Borrower to the Banks, but without affecting or
impairing in any manner the liability of Holdings under the other provisions of
this Guaranty.  Prior to the transfer by Holdings of any note or negotiable
instrument evidencing any indebtedness of the Borrower to Holdings, Holdings
shall mark such note or negotiable instrument with a legend that the same is
subject to this subordination.

          13.09  Waiver.  (a)  Holdings waives any right to require the Agent or
                 ------                                                         
the Banks to (i) proceed against the Borrower, any other guarantor or any other
party, (ii) proceed against or exhaust any security held from the Borrower, any
other guarantor or any other party or (iii) pursue any other remedy in the
Agent's or the Banks' power whatsoever.  Holdings waives any defense based on or
arising out of any defense of the Borrower, any other guarantor or any other
party other than payment in full of the indebtedness (other than

                                     -126-
<PAGE>
 
payment), including, without limitation, any defense based on or arising out of
the disability of the Borrower, any other guarantor or any other party, or the
unenforceability of the indebtedness or any part thereof from any cause, or the
cessation from any cause of the liability of the Borrower other than to the
extent of payment in full of the indebtedness.  The Agent and the Banks may, in
accordance with the Credit Documents, at their election, foreclose on any
security held by the Agent, the Collateral Agent or the Banks by one or more
judicial or nonjudicial sales, whether or not every aspect of any such sale is
commercially reasonable (to the extent such sale is permitted by applicable
law), or exercise any other right or remedy the Agent and the Banks may have
against the Borrower or any other party, or any security, without affecting or
impairing in any way the liability of Holdings hereunder except to the extent
the indebtedness has been paid.  Holdings waives any defense arising out of any
such election by the Agent and the Borrower, even though such election operates
to impair or extinguish any right of reimbursement or subrogation or other right
or remedy of Holdings against the Borrower or any other party or any security.

          (b)  Except as otherwise specifically required hereunder, Holdings
waives all presentments, demands for performance, protests and notices,
including, without limitation, notices of nonperformance, notices of protest,
notices of dishonor, notices of acceptance of this Guaranty, and notices of the
existence, creation or incurring of new or additional indebtedness.  Holdings
assumes all responsibility for being and keeping itself informed of the
Borrower's financial condition and assets, and of all other circumstances
bearing upon the risk of non-payment of the indebtedness and the nature, scope
and extent of the risks which Holdings assumes and incurs hereunder, and agrees
that the Agent and the Banks shall have no duty to advise Holdings of
information known to them regarding such circumstances or risks.

          13.10  Guaranty Continuing.  This Guaranty is a continuing one and all
                 -------------------                                            
liabilities to which it applies or may apply under the terms hereof shall be
conclusively presumed to have been created in reliance hereon.  No failure or
delay on the part of any Bank, of any holder of any Note, or issuer of, or
participant in, any Letter of Credit in exercising any right, power or privilege
hereunder shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies herein expressly specified are cumulative and not
exclusive of any rights or remedies which any Bank or any subsequent holder of a
Note, or issuer of, or participant in, a Letter of Credit would otherwise have.
No notice to or demand on Holdings in any case shall entitle Holdings to any
other or further notice or demand in similar or other circumstances or
constitute a waiver of the rights of the Bank or any holder, creator or
purchaser to any other or further action in any circumstances without notice or
demand.

subsequent holder of a Note or issuer of, or participant in, any Letter of
Credit for repayment or recovery of any amount or amounts received in payment or
on account of any of the indebtedness and any of the aforesaid payees repays all
or part of said amount by reason of (a) any judgment, decree or order of any
court or administrative body having jurisdiction over such payee or any of its
property, or (b) any settlement or compromise of any such claim effected by such
payee with any such claimant (including the Borrower) then and in such event
Holdings agrees that any such judgment, decree, order, settlement or compromise
shall be binding upon Holdings, notwithstanding any revocation hereof or the can
cellation of any Note, or other instrument evidencing any liability of the
Borrower, and Holdings shall be and remain liable to the aforesaid payees
hereunder for the amount so repaid or recovered to the same extent as if such
amount had never originally been received by any such payee.

Agreement or under any of the other Credit Documents, including, without
limitation, all interests in Obligations purchased by such Bank pursuant to
Section 14.06(b), and all other claims of any nature or description arising out
of or connected with this Agreement or any other Credit Document, irrespective
of whether or not such Bank shall have made any demand hereunder and although
said Obligations, liabilities or claims, or any of them, shall be contingent or
unmatured.

          14.04  Benefit of Agreement.  (a)  This Agreement shall be binding
                 --------------------                                       
upon and inure to the benefit of and be enforceable by the respective successors
and assigns of the parties hereto; provided, however, no Credit Party may assign
                                   --------  -------                            
or transfer any of its rights, obligations or interest hereunder or under any
other Credit Document without the prior written consent of the Banks; and
provided further, that although any Bank may transfer, assign or grant
- ----------------                                                       
participations in its rights hereunder, such Bank shall remain a "Bank" for all
purposes hereunder (and may not transfer or assign all or any portion of its
Commitments or Loans hereunder except as provided in Section 14.04(b)) and the
transferee, assignee or participant, as the case may be, shall not constitute a
"Bank" hereunder; and provided further, that no Bank shall transfer or grant any
                      ----------------                                          
participation under which the participant shall have rights to approve any
amendment to or waiver of this Agreement or any other Credit Document except to
the extent such amendment or waiver would (i) extend the final scheduled
maturity of any Loan, Note or Letter of Credit (unless such Letter of Credit is
not extended beyond the Revolving Loan Maturity Date) in which such participant
is participating, or reduce the rate or extend the time of payment of interest
or Fees thereon (except in connection with a waiver of applicability of any
post-default increase in interest rates) or reduce the principal amount thereof,
or increase the Commitments in which such participant is participating over the
amount thereof then in effect (it being understood that a waiver of any Default
or Event of Default or of a mandatory reduction in the Total Commitment shall
not constitute a change in the terms of any Commitment, and that an increase in
any Commitment shall be permitted without the consent of any participant if the
participant's participation is not increased as a result thereof), (ii) consent
to the assignment or transfer by any Credit Party of any of its rights and
obligations under this Agreement or (iii) release all or substantially all of
the Collateral under all of the Security Documents (except as expressly provided
in the Credit Documents) supporting the Loans hereunder in which such
participant is participating.  In the case of any such participation, the
participant shall not have any rights under this Agreement or any of the other
Credit Documents (the participant's rights against such Bank in respect of such
participation to be those set forth in the agreement executed by such Bank in
favor of the participant relating thereto) and all

                                     -130-
<PAGE>
 
amounts payable by the Borrower hereunder shall be determined as if such Bank
had not sold such participation.

          (b)  Notwithstanding the foregoing, any Bank (or any Bank together
with one or more other Banks) may (x) (A) pledge its Loans and/or Notes
hereunder to a Federal Reserve Bank in support of borrowings made by such Bank
from such Federal Reserve Bank or (B) assign all or a portion of its Loans or
Commitments and related outstanding Obligations hereunder to its parent company,
principal office and/or any Affiliate of such Bank which is at least 50% owned
by such Bank or its parent company or to one or more other Banks or to a Related
Fund or (y) assign all or a portion equal to at least $5,000,000, of such Loans
or Commitments and related outstanding Obligations hereunder to one or more
Eligible Transferees each of which assignees shall become a party to this
Agreement as a Bank by execution of an assignment and assumption agreement
substantially in the form of Exhibit L (appropriately completed); provided that:
                                                                  --------
(i) at such time Part A of Schedule I shall be deemed modified to reflect the
Commitments of such new Bank and of the existing Banks; (ii) new Notes will be
issued to such new Bank and to the assigning Bank upon the request of such new
Bank or assigning Bank, such new Notes to be in conformity with the requirements
of Section 1.05 to the extent needed to reflect the revised Commitments; (iii)
the consent of the Agent, which consent shall not be unreasonably withheld,
shall be required in connection with any assignment (provided, however, that no
                                                     --------  -------         
such consent shall be required in the case of any assignment to another Bank,
any Bank's Affiliate or a Related Fund); and (iv) the Agent shall receive at the
time of each such assignment, from the assigning Bank, the payment of a non-
refundable assignment fee of $3,000.  To the extent of any assignment pursuant
to this Section 14.04(b), the assigning Bank shall be relieved of its
obligations hereunder with respect to its assigned Commitments.  No transfer or
assignment under this Section 14.04(b) will be effective until recorded by the
Agent on the Register pursuant to Section 8.16.  At the time of each assignment
pursuant to this Section 14.04(b) to a Person which is not already a Bank
hereunder and which is not a United States person (as such term is defined in
Section 7701(a)(30) of the Code) for Federal income tax purposes, the respective
assignee Bank shall provide to Holdings and the Agent the appropriate Internal
Revenue Service Forms (and, if applicable, a Section 4.04(b)(ii) Certificate)
required by Section 4.04(b).

          14.05  No Waiver; Remedies Cumulative.  No failure or delay on the
                 ------------------------------                             
part of the Agent or any Bank or any holder of any Note in exercising any right,
power or privilege hereunder or under any other Credit Document and no course
of dealing between Holdings or any other Credit Party and the Agent or any Bank
or the holder of any Note shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, power or privilege hereunder or under
any other Credit Document preclude any other or further exercise thereof or the
exercise of any other right, power or privilege hereunder or thereunder.  The
rights, powers and remedies herein or in any other Credit Document expressly
provided are cumulative and not exclusive of any rights, powers or remedies

                                     -131-
<PAGE>
 
which the Agent or any Bank or the holder of any Note would otherwise have.  No
notice to or demand on any Credit Party in any case shall entitle any Credit
Party to any other or further notice or demand in similar or other circumstances
or constitute a waiver of the rights of the Agent or any Bank or the holder of
any Note to any other or further action in any circumstances without notice or
demand.

          14.06  Payments Pro Rata.  (a)  The Agent agrees that promptly after
                 -----------------                                            
its receipt of each payment from or on behalf of either Borrower in respect of
any Obligations hereunder, it shall distribute such payment to the Banks pro
                                                                         ---
rata based upon their respective shares, if any, of the Obligations with respect
- ----                                                                            
to which such payment was received.

          (b)  Each of the Banks agrees that, if it should receive any amount
hereunder (whether by voluntary payment, by realization upon security, by the
exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Credit Documents, or
otherwise), which is applicable to the payment of the principal of, or interest
on, the Loans, Unpaid Drawings or Fees, of a sum which with respect to the
related sum or sums received by other Banks is in a greater proportion than the
total of such Obligation then owed and due to such Bank bears to the total of
such Obligation then owed and due to all of the Banks immediately prior to such
receipt, then such Bank receiving such excess payment shall purchase for cash
without recourse or warranty from the other Banks an interest in the Obligations
of the respective Credit Party to such Banks in such amount as shall result in a
proportional participation by all the Banks in such amount; provided that if all
                                                            --------            
or any portion of such excess amount is thereafter recovered from such Bank,
such purchase shall be rescinded and the purchase price restored to the extent
of such recovery, but without interest.

          14.07  Calculations; Computations.  (a)  The financial statements to
                 --------------------------                                   
be furnished to the Banks pursuant hereto shall be made and prepared in
accordance with generally accepted accounting principles in the United States
consistently applied throughout the periods involved (except as set forth in the
notes thereto or as otherwise disclosed in writing by the Borrower to the
Banks); provided that, except as otherwise specifically provided herein, all
        --------                                                             
computations of Excess Cash Flow and all computations determining compliance
with Sections 9.04 and 9.08 through 9.13, inclusive, including the definitions
used therein, shall utilize accounting principles and policies in conformity
with those used to prepare the historical financial statements delivered to the
Banks pursuant to Section 5.15.

          (b)  All computations of interest and Fees hereunder shall be made on
the basis of a year of 360 days for the actual number of days (including the
first day but excluding the last day) occurring in the period for which such
interest or Fees are payable.

          SENIOR SUBORDINATED LOAN AGREEMENT, dated as of October 27, 1997,
among Physician Health Corporation, a corporation organized and existing under
the laws of the State of Delaware ("Holdings"), PHC Holding Corporation, a
corporation organized and existing under the laws of the State of Georgia and a
wholly-owned Subsidiary of Holdings (the "Borrower"), the financial institutions
party hereto from time to time (each a "Lender" and, collectively, the
"Lenders"), and Paribas Capital Funding LLC ("PCF"), as agent (in such capacity,
the "Agent") for the Lenders.  Unless otherwise defined herein, all capitalized
terms used herein and defined in Section 8 are used herein as therein defined.


                             W I T N E S S E T H :


          WHEREAS, the Borrower has requested that the Lenders lend to the
Borrower $15,000,000 for the purposes specified herein; and

          WHEREAS, subject to and upon the terms and conditions herein set
forth, the Lenders are willing to make loans to the Borrower in an aggregate
amount of $15,000,000;

          NOW, THEREFORE, IT IS AGREED:

          Section 1.  Amount and Terms of Loans.
                      ------------------------- 

          1.01 The Loans. (a) Subject to and upon the terms and conditions set
               ---------
forth herein, each Lender severally agrees to make, on the Initial Funding Date
and on the Subsequent Funding Date, a loan in Dollars (each a "Loan" and,
collectively, the "Loans") to the Borrower in a principal amount equal to such
Lender's Initial Commitment and Subsequent Commitment, respectively. Any amount
of any Loan prepaid or repaid may not be reborrowed. The Loans shall be made on
notice given by the Borrower to the Agent at its Notice Office no later than
1:00 P.M. (New York time) on the Business Day preceding the applicable Funding
Date, which notice shall be in writing and shall be irrevocable and shall
specify the Funding Date (which shall be a Business Day). The Agent shall
promptly give each Lender notice of the Agent's receipt from the Borrower of
such written notice.

          (b)  No later than 12:00 noon (New York time) on the applicable
Funding Date, each Lender will make available at the Payment Office of the Agent
the amount of the Loan to be made by it, in immediately available funds, and the
Agent will make available to the Borrower at the Payment Office the aggregate of
the amounts so made available by the Lenders. Unless the Agent shall have been
notified by any Lender prior 
<PAGE>
 
to such Funding Date that such Lender does not intend to make available to the
Agent on such Funding Date funds in the amount of such Lender's Commitment, the
Agent may assume that such Lender has made such amount available to the Agent
and the Agent may, in reliance upon such assumption, make available to the
Borrower a corresponding amount. If such corresponding amount is not in fact
made available to the Agent by such Lender, the Agent shall be entitled to
recover such corresponding amount on demand from such Lender. If such Lender
does not pay such corresponding amount forthwith upon the Agent's demand
therefor, the Agent shall promptly notify the Borrower and the Borrower shall
immediately pay such corresponding amount to the Agent. The Agent shall also be
entitled to recover on demand from such Lender or the Borrower, as the case may
be, interest on such corresponding amount in respect of each day from the date
such corresponding amount was made available by the Agent to the Borrower until
the date such corresponding amount is recovered by the Agent, at a rate per
annum equal to (i) if recovered from such Lender, the cost to the Agent of
acquiring overnight federal funds and (ii) if recovered from the Borrower, the
rate of interest applicable to the Loans, as determined pursuant to Section
1.02. Nothing in this subsection (b) shall be deemed to relieve any Lender from
its obligation to make its Loan hereunder or to prejudice any rights which the
Borrower may have against any Lender as a result of any failure by such Lender
to make its Loan hereunder. It is understood that no Lender shall be responsible
for any default by any other Lender of its obligation to make its Loan hereunder
and that each Lender shall be obligated to make its Loan provided to be made by
it hereunder regardless of the failure of any other Lender to make its Loan
hereunder.

          (c)  The Borrower's obligation to pay the principal of, and interest
on, the Loans made by each Lender shall be evidenced by a promissory note to the
order of such Lender, in substantially in the form of Exhibit A, duly executed
and delivered by the Borrower on the Initial Funding Date or the Subsequent
Funding Date, as the case may be (each a "Note" and, collectively, the "Notes"),
and in a stated principal amount equal to the Commitment of such Lender in
respect of such Funding Date.

          1.02 Interest. (a) The Borrower agrees to pay interest in respect of
               --------
the unpaid principal amount of each Loan from the date such Loan is made until
the maturity thereof (whether by acceleration or otherwise), at a rate which (i)
shall at all times be equal to 12% per annum with respect to Loans made on the
Initial Funding Date and (ii) shall be the rate that is, on the Subsequent
Funding Date, the greater of 12% per annum or the rate per annum for 5 year U.S.
Treasuries (as determined by the Agent) plus 6%; with respect to Loans made on
the Subsequent Funding Date.

          (b)  Overdue principal and, to the extent permitted by law, overdue
interest in respect of each Loan and any other overdue amount payable hereunder
shall, in each case, bear interest at a rate per annum equal to the then
applicable interest rate plus 2%, in each case with such interest to be payable
on demand.

                                       2
<PAGE>
 
          (c)  Accrued and unpaid interest shall be payable quarterly in arrears
on each Quarterly Payment Date, on any repayment (on the amount repaid), at
maturity (whether by acceleration or otherwise) and, after such maturity, on
demand.

          1.03 Fees. The Borrower agrees to pay to the Agent for distribution to
               ---- 
each Lender, quarterly in arrears on each Quarterly Payment Date and on the date
of each reduction or termination of the Subsequent Commitment, a fee (the
"Unused Commitment Fee") computed at a rate for each day equal to .50% per annum
of the Subsequent Commitment of such Lender.

          1.04 Mandatory Reduction and Termination of Subsequent Commitment. (a)
               ------------------------------------------------------------
The Subsequent Commitment of each Lender shall automatically be reduced as of
the date of any payment (including scheduled payments) of the principal of the
Metroplex Note by an amount equal to the amount of such payment; and

          (b)  The Subsequent Commitment shall terminate upon the earliest to
occur of (i) repayment in full of the outstanding Loans, (ii) the thirtieth day
after the delivery by Holdings or the Borrower of a report pursuant to Section
5.01 which evidences that a Credit Event Date has occurred, (iii) the fifth day
after the consummation of a Qualified IPO or (iv) April 1, 2002.

          Section 2.  Repayment; Prepayments; Payments; Taxes.
                      --------------------------------------- 

          2.01 Payment of Loan. The unpaid principal amount of each Loan plus
               ---------------
all accrued and unpaid interest thereon and all other amounts owed hereunder
with respect thereto shall be paid in full in cash on the Maturity Date.

          2.02 Mandatory and Voluntary Prepayments. (a) The Borrower may, upon
               -----------------------------------
not less than two Business Days' and not more than five Business Days' prior
written notice to the Lenders (which notice shall be irrevocable), at any time
and from time to time, prepay the Loans, in whole; provided, however, that no
                                                   --------  -------
such prepayment shall be made unless (x) there is no Senior Debt outstanding and
all commitments under the Senior Credit Agreement have been terminated or (y)
the Senior Credit Agreement expressly permits such payments or the required
Banks thereunder have consented to such payment. In connection with any
voluntary prepayment in whole, the Borrower shall prepay the Loan at the
prepayment price set forth below (plus all accrued interest):

Prepayment Date During the Period                                  Being Paid
- ---------------------------------                                 --------------

From the Initial Funding Date to                                      105%
     but not including the first
     anniversary of the Initial Funding Date

From the first anniversary of the Initial Funding                     104%
     Date to but not including the second
     anniversary of the Initial Funding Date

     Date to but not including the third
     anniversary of the Initial Funding Date

From the fifth anniversary of the Initial Funding                     100%
     Date and at any time thereafter

          (b)  The Borrower shall notify the Bank Agent of any prepayment to be
made pursuant to Section 2.02(a) at least five Business Days prior to such
prepayment (unless shorter notice is satisfactory to the Bank Agent).
Notwithstanding the foregoing or the provisions of Section 2.02(d) below, the
Lenders and the Borrower agree and acknowledge that the Senior Credit Agreement
prohibits any payments that would otherwise be made to the Lenders under Section
2.02(a) or (d) and, as a result thereof, no payment shall be made to the Lenders
under Section 2.02(a) or (d) unless and only to the extent the Senior Credit
Agreement is amended or modified to provide that such amounts may be paid to the
Lenders.

          (c)  All prepayments (whether voluntary or mandatory) shall include
payment of accrued interest on the principal amount of the Loans so prepaid and
shall be applied to payment of accrued interest before application to principal.
Mandatory prepayments under Section 2.02(d) made on or before November 5, 1999
shall not include any prepayment premiums. Any mandatory prepayment made after
November 5, 1999 shall include a prepayment premium equal to 103% of the
principal being paid. Any

                                       4
<PAGE>
 
payment of the Loans as a result of an Event of Default resulting from a Change
of Control shall be deemed a voluntary prepayment for the purposes of this
Section 2 and shall be paid at the payment price specified in Section 2.02(a) as
if such payment had been voluntary. All prepayments which are applied to
principal will be applied on a pro rata basis to all Loans.
                               --- ----

          (d)  The Borrower will apply, or cause its applicable Subsidiaries to
apply, the following amounts first to the permanent reduction of the then
                             -----                                       
outstanding Senior Debt and any commitments thereunder to make revolving loans,
acquisition loans or issue letters of credit (if required under the terms of the
Senior Debt) and next, to the extent not used to prepay the Senior Debt in
                 ----                                                     
permanent reduction thereof or to permanently reduce the commitments therefor,
to the Obligations in the manner set forth in Section 2.02(c):

          (i)  on the date of the receipt thereof by Holdings or any Subsidiary
     of Holdings, the Borrower shall repay, in accordance with Section 2.02(c),
     an amount equal to (A) 100% of the cash proceeds (net of underwriting
     discounts and commissions and all other reasonable costs associated with
     such transaction) from any sale or issuance after the Effective Date of
     equity of Holdings or any Subsidiary of Holdings, other than proceeds of
     (v) equity issued on the Initial Funding Date and after the Initial Funding
     Date as consideration to be paid for Post-Closing Acquisitions, (w) the
     equity issued under the Equity Call Agreement, (x) Permitted Equity
     Issuances (as defined in the Senior Credit Agreement), (y) equity issued to
     the Bank Agent or an Affiliate thereof in connection with its investment of

     Offering Proceeds; provided that, with respect to any proceeds of equity
     sold or issued to officers or employees of Holdings or the Borrower
     ("Employee Stock Proceeds"), such Employee Stock Proceeds shall only be
     required to be paid at such time or times that the aggregate amount thereof
     not previously applied to the Loans equals or exceeds $100,000, and
     provided further that from and after April 30, 1998, Holdings shall not use
     or permit to be used any Excluded Public Offering Proceeds to make any
     voluntary prepayment of any Indebtedness (other than Senior Debt or the
     Loans); and (B) 100% of the cash proceeds (net of underwriting discounts
     and commissions, loan fees and all other reasonable costs associated with
     such transaction) from any incurrence of any Indebtedness by Holdings or
     any Subsidiary of Holdings (other than Indebtedness permitted to be
     incurred pursuant to Section 6.04 as said Section is in effect on the
     Effective Date);

          (ii) on each date after the Effective Date on which Holdings or any
     Subsidiary of Holdings receives Net Sale Proceeds from any sale or other
     disposition of assets (including capital stock and securities other than
     capital stock or securities the proceeds from the sale of which are
     recaptured pursuant to Section 2.02(d)(i)(A) or would be recaptured under
     Section 2.02(d)(i)(A) but for the proviso

     course of business, (B) other sales of assets the proceeds of which are
     used, or irrevocably committed to be used, to purchase, within 180 days
     from the date of sale, properties or assets to be used in the business of
     Holdings or its Subsidiaries, provided that the aggregate amount of Net
     Sale Proceeds excluded pursuant to this clause (B) shall not exceed
     $600,000 in the aggregate in any one fiscal year, and (C) other sales of
     assets the Net Sale Proceeds of which do not exceed, in the aggregate,
     $100,000 in any one fiscal year;

          (iii) on each date after the Effective Date on which Holdings or any
     Subsidiary of Holdings receives cash proceeds of any Recovery Event, an

     Event of Default then exists and (A) such proceeds are not in excess of
     $500,000 for any one occurrence and $1,500,000 for all occurrences after

     on or prior to such date stating that such proceeds shall be used to
     replace or restore any properties or assets in respect of which such

     a Subsidiary of Holdings and pursuant to the terms of such lease Holdings

     such proceeds to replace the leased equipment, then such proceeds shall not
     be required to be repaid pursuant to the provisions of this Section

     used to replace the leased equipment; and

          (iv) on each date after the Effective Date upon which Holdings or any

     reasonable expenses incurred in connection with obtaining such proceeds).

          (e)  If Holdings has not consummated an initial public offering of
Holdings capital stock on or before the date that is eighteen months after the
date hereof, then the entire outstanding principal amount of the Loans shall be
due and payable, and shall be repaid, in full on December 31, 2002.

          2.03 Method and Place of Payment. Except as otherwise specifically
               ---------------------------                                   
provided herein, all payments under this Agreement or any Note shall be made to
the Agent for the account of the Lenders not later than 12:00 noon (New York
time) on the date when due and shall be made in Dollars and in immediately
available funds at the Payment Office of the Agent. Whenever any payment to be
made hereunder or under any Note shall be stated to be due on a day which is not
a Business Day, the due date thereof shall be extended to the next succeeding
Business Day and, with respect to payments of principal, interest shall be
payable at the applicable rate during such extension.

          2.04 Net Payments. (a) All payments made by Holdings or the Borrower
               ------------                                                  
hereunder or under any Note will be made without setoff, counterclaim or other
defense.  Except as provided in Section 2.04(b), all such payments will be made
free and clear of, and without deduction or withholding for, any present or
future taxes, levies, imposts, duties, fees, assessments or other charges of
whatever nature now or hereafter imposed by any jurisdiction or by any political
subdivision or taxing authority thereof or therein with respect to such payments
(but excluding, except as provided in the second succeeding sentence, any tax
imposed on or measured by the net income of a Lender pursuant to the laws of the
jurisdiction or any political subdivision or taxing authority thereof or therein
in which the principal office or applicable lending office of such Lender is
located) and all interest, penalties or similar liabilities with respect thereto
(collectively, "Taxes").  If any Taxes are so levied or imposed, the Borrower
and Holdings jointly and severally agree to

                                       7
<PAGE>
 
pay the full amount of such Taxes, and such additional amounts as may be
necessary so that every payment of all amounts due hereunder or under any Note,
after withholding or deduction for or on account of any Taxes, will not be less
than the amount provided for herein or in such Note. If any amounts are payable
in respect of Taxes pursuant to the preceding sentence, then Holdings and the
Borrower jointly and severally shall be obligated to reimburse each Lender, upon
the written request of such Lender, for taxes imposed on or measured by the net
income of such Lender pursuant to the laws of the jurisdiction or any political
subdivision or taxing authority thereof or therein in which the principal office
or applicable lending office of such Lender is located as such Lender shall
determine are payable by such Lender in respect of such amounts so paid to or on
behalf of such Lender pursuant to the preceding sentence and in respect of any
amounts paid to or on behalf of such Lender pursuant to this sentence. The
Borrower or Holdings, as the case may be, will furnish to the Agent within 45
days after the date of the payment of any Taxes due pursuant to applicable law
certified copies of tax receipts evidencing such payment by the Borrower or
Holdings. The Borrower and Holdings jointly and severally agree to indemnify and
hold harmless each Lender, and reimburse such Lender upon its written request,
for the amount of any Taxes so levied or imposed and paid by such Lender.

          (b)  Each Lender that is not a United States person (as such term is
defined in Section 7701(a)(30) of the Code) agrees to deliver to the Borrower
and the Agent on or prior to the Effective Date, or in the case of a Lender that
is an assignee or transferee of an interest under this Agreement pursuant to
Section 12.04 (unless the respective Lender was already a Lender hereunder
immediately prior to such assignment or transfer), on the date of such
assignment or transfer to such Lender, (i) two accurate and complete original
signed copies of Internal Revenue Service Form 4224 or 1001 (or successor forms)
certifying to such Lender's entitlement to a complete exemption from United
States withholding tax with respect to payments to be made under this Agreement
and under any Note, or (ii) if the Lender is not a "bank" within the meaning of
Section 881(c)(3)(A) of the Code and cannot deliver either Internal Revenue
Service Form 4224 or 1001 pursuant to clause (i) above, (x) a certificate
substantially in the form of Exhibit B (any such certificate, a "Section
2.04(b)(ii) Certificate") and (y) two accurate and complete original signed
copies of Internal Revenue Service Form W-8 (or successor form) certifying to
such Lender's entitlement to a complete exemption from United States withholding
tax with respect to payments of interest to be made under this Agreement and
under any Note. In addition, each Lender agrees that from time to time after the
Effective Date, when a lapse in time or change in circumstances renders the
previous certification obsolete or inaccurate in any material respect, it will
deliver to the Borrower and the Agent two new accurate and complete original
signed copies of Internal Revenue Service Form 4224 or 1001, or Form W-8 and a
Section 2.04(b)(ii) Certificate, as the case may be, and such other forms as may
be required in order to confirm or establish the entitlement of such Lender to a
continued exemption from or reduction in United States withholding tax with
respect to payments under this Agreement and any Note, or it shall immediately
notify the Borrower and the

                                       8
<PAGE>
 
Agent of its inability to deliver any such Form or Certificate, in which case
such Lender shall not be required to deliver any such Form or Certificate
pursuant to this Section 2.04(b). Notwithstanding anything to the contrary
contained in Section 2.04(a), but subject to the immediately succeeding
sentence, (x) the Borrower shall be entitled, to the extent it is required to do
so by law, to deduct or withhold income or similar taxes imposed by the United
States (or any political subdivision or taxing authority thereof or therein)
from interest, fees or other amounts payable hereunder for the account of any
Lender that is not a United States person (as such term is defined in Section
7701(a)(30) of the Code) for U.S. Federal income tax purposes to the extent that
such Lender has not provided to the Borrower U.S. Internal Revenue Service Forms
that establish a complete exemption from such deduction or withholding and (y)
the Borrower shall not be obligated pursuant to Section 2.04(a) hereof to gross-
up payments to be made to a Lender in respect of income or similar taxes imposed
by the United States if (I) such Lender has not provided to the Borrower the
Internal Revenue Service Forms required to be provided to the Borrower pursuant
to this Section 2.04(b) or (II) in the case of a payment, other than interest,
to a Bank described in clause (ii) above, to the extent that such forms do not
establish a complete exemption from withholding of such taxes. Notwithstanding
anything to the contrary contained in the preceding sentence or elsewhere in
this Section 2.04, the Borrower agrees to pay additional amounts and to
indemnify each Lender in the manner set forth in Section 2.04(a) (without regard
to the identity of the jurisdiction requiring the deduction or withholding) in
respect of any amounts deducted or withheld by it as described in the
immediately preceding sentence as a result of any changes after the Effective
Date in any applicable law, treaty, governmental rule, regulation, guideline or
order, or in the interpretation thereof, relating to the deducting or
withholding of income or similar Taxes.

               -----------------

payment by Holdings or any of its Subsidiaries of any amounts with respect to

that such Subsidiary shall be released from all of its obligations under such
indebtedness and such indebtedness is assumed by Holdings and shall be
subordinated to all indebtedness under this Agreement and refinancings thereof
with such subordination provisions to be in form and substance satisfactory to
the Required Lenders; provided, however, that notwithstanding the foregoing,
                      --------  -------

reasonably be expected to have a material adverse effect on the rights or
remedies of the Lenders or the Agent, or on the ability of any Loan Party to

occurrence of the Subsequent Funding Date being deemed to constitute a
representation and warranty that the matters specified in this Section 4 are
true and correct on and as of such date:

          4.01 Corporate Status. Each Loan Party and its Subsidiaries (other

assets and to transact the business in which it is engaged and presently
proposes to engage and (iii) is duly qualified and is authorized to do business
and is in good standing in each jurisdiction where the ownership, leasing or

performance, business, assets, nature of assets, liabilities, operations,

                                       17
<PAGE>
 
properties, condition (financial or otherwise) or prospects of such Loan Party

and provisions of each of the Documents to which it is party and has taken all
necessary corporate action (or limited liability company or partnership action
if applicable) to authorize the execution, delivery and performance by it of
each of such Documents. Each Loan Party and its Subsidiaries has duly executed
and delivered each of the Documents to which it is party, and each of such
Documents constitutes its legal, valid and binding obligation enforceable in
accordance with its terms, except as the enforceability thereof may be limited
by bankruptcy, reorganization, moratorium or similar laws relating to or

(regardless of whether the issue of enforceability is considered in a proceeding
in equity or at law).

          4.03 No Violation. Neither the execution, delivery or performance by
               ------------

Party or its Subsidiaries pursuant to the terms of any indenture, mortgage, deed
of trust, credit agreement or loan agreement, or any other agreement, contract
or instrument to which any of them are a party or by which any of their property
or assets is bound or to which any of them may be subject or (iii) will violate

          4.05 Financial Statements; Financial Condition; Undisclosed
               ------------------------------------------------------
Liabilities; Projections; Etc. (i) The audited consolidated balance sheets of
- -----------------------------
Holdings as at December 31, 1996 and June 30, 1997 and the related consolidated
statements of operations and cash flows of Holdings for the fiscal year or six
month period, as the case may be, ended as of such dates, and the financial
statements of each company listed on Schedule X

                                       18
<PAGE>
 
at the dates listed on Schedule X and for the fiscal periods ended as of the
dates listed on Schedule X, which, in the case of the annual statements, have
been audited by Arthur Andersen L.L.P., in the case of the financial statements
of Holdings and have been examined or reviewed by the independent certified
public accountants listed on Schedule X, in the case of the other financial
statements, who delivered unqualified opinions in respect thereto and (ii) the
pro forma (after giving effect to the Transaction and the related financing
thereof) consolidated balance sheet of Holdings and the Borrower as at the
Initial Funding Date, copies of all of which financial statements referred to in
the pre ceding clauses (i) and (ii) have heretofore been furnished to the Agent,
present fairly the financial position of the respective entities at the dates of
said statements and the results of operations for the period covered thereby
(or, in the case of the pro forma balance sheet, present a good faith estimate
of the pro forma finan cial condition of Holdings and its Subsidiaries (after
giving effect to the Transaction) on a consolidated basis at the date thereof).
All such financial statements have been prepared in accordance with generally
accepted accounting principles and practices consistently applied except to the
extent provided in the notes to said financial statements and with respect to
interim financial statements, subject to normal year end adjustments. Since June
30, 1997, there has been no material adverse change in the performance,
business, assets, nature of assets, liabilities, operations, properties,
condition (financial or otherwise) or prospects of Holdings and its Subsidiaries
taken as a whole.

          (b)  On and as of the Initial Funding Date, on a pro forma basis after
giving effect to the Transaction and all other transactions contemplated by the
Documents as of such date and to all Indebted  ness (including, without
limitation, the Loans) being incurred in connection with the Transaction, and
Liens created, and to be created, by each Loan Party in connection therewith:
(a) the sum of the assets (including all contribution and subrogation rights and
other intangible assets), at a fair valuation, of each Loan Party will exceed
its debts; (b) no Loan Party has incurred or intends to, or believes that it
will, incur debts beyond its ability to pay such debts as such debts mature; and
(c) each Loan Party will have sufficient capital with which to conduct its
business.  For purposes of this Section 4.05(b) "debt" means any liability on a
claim, and "claim" means (i) right to payment, whether or not such a right is
reduced to judgment, liquidated, unliquidated, fixed, contingent, matured,
unmatured, disputed, undisputed, legal, equitable, secured, or unsecured or (ii)
right to an equitable remedy for breach of performance if such breach gives rise
to a payment, whether or not such right to an equitable remedy is reduced to
judgment, fixed, contingent, matured, unmatured, subordinated, disputed,
undisputed, secured or unsecured.

          (c)  Except as fully reflected in the financial statements and the
notes related thereto described in Section 4.05(a), there were as of the Initial
Funding Date (and after giving effect to the Transaction and the other
transactions contemplated hereby and by the Documents) no liabilities or
obligations with respect to Holdings or any of its Subsidiaries of any nature
whatsoever (whether absolute, accrued, contingent or otherwise and whether

                                       19
<PAGE>
 
or not due) which, either individually or in aggregate, could reasonably be
expected to be material to Holdings and its Subsidiaries taken as a whole. As of
the Initial Funding Date, neither Holdings nor any of its Subsidiaries knows of
any basis for the assertion against Holdings or any of its Subsidiaries of any
liability or obligation of any nature whatsoever that is not fully reflected in
the financial statements and the notes related thereto described in Section
4.05(a) which, either individually or in the aggregate, could reasonably be
expected to be material to Holdings and its Subsidi aries taken as a whole. As
of the Initial Funding Date (and after giving effect to the Transaction) none of
Holdings or any of its Subsidiaries will have any outstanding Indebtedness or
preferred stock other than (i) the Loans, (ii) the Senior Debt, (iii) the
Existing Indebtedness and (iv) Holdings Preferred Stock.

          (d)  On and as of the Initial Funding Date, the Projections have been
prepared in good faith by Holdings and there are no statements or conclusions in
any of the Projections which are based upon or include information known to
Holdings to be misleading or which fail to take into account material infor
mation regarding the matters reported therein.  On the Initial Funding Date,
each of Holdings and the Borrower believes that the Projections were reasonable
and attainable (although actual results may differ from the Projections and no
representation is made that the Projections will in fact be attained).

          4.06 Litigation. There are no actions, suits or proceedings pending
               ----------
or, to the best knowledge of each Loan Party and its Subsidiaries, threatened
(i) with respect to any Document or the transactions contemplated thereby, or
(ii) that are reasonably likely to materially and adversely affect the
performance, business, assets, nature of assets, liabilities, operations,
properties, condition (financial or otherwise) or prospects of the Loan Parties
and their Subsidiaries taken as a whole.

          4.07 True and Complete Disclosure. All factual information (taken as a
               ----------------------------  
whole) heretofore or contemporaneously furnished by or on behalf of any of the
Loan Parties or their Subsidiaries in writing to any Lender (including, without
limitation, all information contained in the Documents) for purposes of or in
connection with this Agreement, the other Loan Documents or Warrant Documents or
any transaction contemplated herein is, and all other such factual information
(taken as a whole) hereafter furnished by or on behalf of any of the Loan
Parties and their Subsidiaries in writing to any Lender or the Agent will be,
true and accurate in all material respects on the date as of which such
information is dated or certified and not incomplete by omitting to state any
material fact.

          4.08 Use of Proceeds; Margin Regulations. (a) All proceeds of the
               -----------------------------------
Loans shall be used by the Borrower to (i) finance, in part, the consummation of
the Transaction and (ii) pay Transaction Fees and Expenses; provided, however,
                                                            --------  -------
that the proceeds of Loans

                                       20
<PAGE>
 
made on a Subsequent Funding Date occurring after June 30, 1998 may only be used
to pay in full the Metroplex Note.

          (b)  No part of the proceeds of any Loan will be used to purchase or
carry any Margin Stock or to extend credit for the purpose of purchasing or
carrying any Margin Stock. Neither the making of any Loan nor the use of the
proceeds thereof will violate or be inconsistent with the provisions of
Regulation G, T, U or X of the Board of Governors of the Federal Reserve System.

          4.09  Tax Returns and Payments. Each of the Loan Parties and each of
                ------------------------
their Subsidiaries has timely filed or caused to be timely filed (including
pursuant to any valid extensions of time for filing) with the appropriate taxing
authority, all material returns, statements, forms and reports for taxes (the
"Returns") required to be filed by or with respect to the income, properties or
operations of such Loan Party or such Subsidiary. The Returns accurately reflect
in all material respects all liability for taxes of such Loan Party or such
Subsidiary as a whole for the periods covered thereby. Each of the Loan Parties
and each of their Subsidiaries has paid all material taxes payable by it which
have become due other than those contested in good faith and for which adequate
reserves have been established in accordance with generally accepted accounting
principles. There is no material action, suit, proceeding, investigation, audit,
or claim now pending or, to the best knowledge of any of the Loan Parties and
each of their Subsidiaries, threatened by any authority regarding any taxes
relating to any Loan Party or any of its Subsidiaries. As of the Initial Funding
Date, none of the Loan Parties or their Subsidiaries has entered into an
agreement or waiver or has been requested to enter into an agreement or waiver
extending any statute of limitations relating to the payment or collection of
taxes of any of the Loan Parties or their Subsidiaries, or is aware of any
circumstances that would cause the taxable years or other taxable periods of any
of the Loan Parties or their Subsidiaries not to be subject to the normally
applicable statute of limitations. None of the Loan Parties or their
Subsidiaries has provided, with respect to themselves or property held by them,
any consent under Section 341 of the Code. None of the Loan Parties or their
Subsidiaries has incurred, or will incur, any material tax liability in
connection with the Transaction or any other transactions contemplated hereby
(it being understood that the representation contained in this sentence does not
cover any future tax liabilities of Holdings or any of its Subsidiaries arising
as a result of the operation of their businesses in the ordinary course of
business).

                ---------------------                                          
Plan (and each related trust, insurance contract or fund) is in substantial
compliance with its terms and with all applicable laws, including, without
limitation, ERISA and the Code; each Plan (and each related trust, if any) which

period, within the meaning of Section 412 of the Code or Section 303 or 304 of
ERISA; all contributions required to be made with respect to a Plan have been
timely made; neither Holdings nor any Subsidiary of Holdings nor any ERISA
Affiliate has incurred any material liability (including any indirect,
contingent or secondary liability) to or on account of a Plan pursuant to

of them without incurring any material liability.

                --------------

Subsidiaries taken as a whole.

          5.12  Register.  The Borrower hereby designates the Agent to serve as

the Borrower's agent, solely for purposes of this Section 5.13, to maintain a
register (the "Register") on which it will record the Loans made by each of the
Lenders and each repayment in respect of the principal amount of the Loans of
each Lender.  Failure to make any such recordation, or any error in such
recordation shall not affect the Borrower's obligations in respect of such
Loans.  With respect to any Lender, the transfer of the rights to the principal
of, and interest on, any Loan shall not be effective until such transfer is
recorded on the Register maintained by the Agent with respect to ownership of
such Loans and prior to such recordation all amounts owing to the transferor
with respect to such Loans shall remain owing to the transferor.  The
registration of an assignment or transfer of all or part of any Loans shall be
recorded by the Agent on the Register only upon the acceptance by the Agent of a
properly executed and delivered assignment and assumption agreement pursuant to
Section 12.04(b).  Coincident with the delivery of such an assignment and
assumption agreement to the Agent for acceptance and registration of assignment
or transfer of all or part of a Loan, or as soon thereafter as practicable, the
assigning or transferor Lender shall surrender the Note evidencing such Loan,
and thereupon one or more new Notes in the same aggregate principal amount shall
be issued to the assigning or transferor Lender and/or the new Lender.  Holdings
and the Borrower jointly and severally agree to indemnify the Agent from and
against any and all losses, 

                                       34

set forth on Schedule VI, 100% of the capital stock and stock equivalents of
each of its Subsidiaries (other than Immaterial Subsidiaries and other than as
permitted in Section 5.15) provided that if the Borrower indirectly owns less
than 100% of the capital stock and stock equivalents of any such Subsidiary on
the Effective Date, the Borrower shall maintain, at least, its percentage of the
capital stock and stock equivalents of such Subsidiary as of the Effective Date
as is set forth on Schedule VI.

          5.14  Observation of Board of Directors.  PCF may designate one
                ---------------------------------                        
individual (the "Observer") to attend all meetings of the Board of Directors of
Holdings (and any committees thereof) in a non-voting observer capacity.  The
Observer shall be entitled to receive all reports, presentations and materials
as if the Observer were a member of the Board of Directors.  Notwithstanding the
foregoing and Section 13(d) of the Warrant Agreement, PCF agrees that PCF and
Paribas Principal Incorporated shall together be entitled to designate only one
observer, as shall be mutually agreed upon by them from time to time.

     representations and warranties contained herein and in the other Documents
     shall be true and correct in all material respects with the same effect as
     though such representations and warranties were made on and as of the date
     of such Permitted Acquisition (both before and after giving effect thereto)
     and no other agreement, contract or instrument to which the Borrower or any
     of its Subsidiaries is a party restricts such Permitted Acquisition;

     Permitted Equity Issuances to be effected by Holdings in connection with
     such Permitted Acquisition;

          (iii) the Borrower shall have provided the Lenders with all
     information provided to its Board of Directors or any of its shareholders
     with respect to such Permitted Acquisition, including without limitation,
     all information required pursuant to the Securities Purchase Agreement and
     such other information related to the Person or business, division or
     product line being acquired and the Permitted Acquisition as the Agent
     shall reasonably request, including without limitation expert reports
     prepared by such accounting, environmental, and/or other experts as the
     Agent shall reasonably request;

          (iv)  (I) as soon as available but not less than three days after the
     execution thereof, a copy of the executed purchase agreement and all

          (v)   calculations are made by the Borrower of the Consolidated EBITDA
     of the Person or business, division or product line being acquired pursuant
     to the respective Permitted Acquisition (determined in accordance with the
     definition of Consolidated EBITDA contained herein, but treating references
     therein and in any other defined terms used in determining Consolidated
     EBITDA to "Holdings" to instead be references to the Person or business,
     division or product line being acquired pursuant to the respective
     Permitted Acquisition), and the amount thereof shall exceed zero for the
     period of four consecutive fiscal quarters (taken as one accounting period)
     most recently ended prior to the date of the Permitted Acquisition (the
     "Calculation Period"); provided, however, in the case of calculations based
                            --------  -------
     on financial statements not audited by a "big-six accounting firm" or other
     nationally recognized accounting firm reasonably acceptable to the Agent,
     the Agent and the Required Lenders shall be satisfied that the Consolidated

                                       36
<PAGE>
 
     EBITDA of such Person or business, division or product line being acquired
     pursuant to the respective Permitted Acquisition exceeds zero for the
     Calculation Period;

          (vi)  the Agent shall be satisfied in its reasonable discretion that
     the proposed Permitted Acquisition will not be reasonably likely to result
     in materially increased liabilities (contingent or otherwise) of Holdings
     or any of its Subsidiaries other than Permitted Seller Notes and Permitted
     Earn-Out Debt incurred in accordance with the provisions of this Agreement
     (including, without limitation, tax, ERISA or environmental liabilities);
     provided, that, so long as the Permitted Acquisition Notice has been given
     --------
     as required above and so long as Holdings has furnished each Lender,
     following request by the Agent, information with respect to liabilities of
     the type described in this clause with all information so requested, if the
     Agent has not notified the Borrower on or prior to the tenth day prior to
     the consummation of the Permitted Acquisition that the Agent has not yet
     been satisfied that the proposed Permitted Acquisition would not be
     reasonably likely to result in materially increased liabilities of Holdings
     or any of its Subsidiaries, such Lender shall be deemed for purposes of
     this clause (vii) to be so satisfied;

          (vii) after giving effect to any additional indebtedness to be
     incurred in the connection therewith and the Consolidated EBITDA of the
     Person or business, division or product line being acquired pursuant to the
     respective Permitted Acquisition determined in accordance with clause
     5.15(a)(vi) above for the Calculation Period, the ratio of Consolidated
     Indebtedness on the last day of the Calculation Period to Consolidated
     EBITDA of Holdings and its Subsidiaries for the Calculation Period, on a
     Pro Forma Basis shall be equal to or less than 3.50:1;

          (xii) recalculations are made by the Borrower of compliance with the
     covenants contained in Sections 6.06 through 6.09, inclusive, for the
     Calculation Period on a Pro Forma Basis, and such recalculations shall show
     that all such covenants would have been complied with throughout the
     Calculation Period on a Pro Forma Basis;

          (ix)  the Borrower in good faith believes, on a Pro Forma Basis (as if
     the Calculation Period were the one-year period following the date of the
     consummation of the respective Permitted Acquisition) that the financial
     covenants contained in such Sections 6.06 through 6.09, inclusive, will
     continue to be met for the one year period following the date of the
     consummation of the respective Permitted Acquisition;

                                       37
<PAGE>
 
          (x)     the purchase price for any Permitted Acquisition may not
     exceed ten times the Consolidated EBITDA of the Person or business,
     division or product line being acquired for the Calculation Period;

          (xi)    the sum of the items described in clauses (I) - (IV) of
     Section 5.15(a)(v) in connection with any single Permitted Acquisition
     shall not exceed $10 million and in connection with all Permitted
     Acquisitions shall not exceed $30 million in the aggregate;

          (xii)   the aggregate amount (determined by using the face amount of
     the debt or the amount payable at maturity, whichever is greater) of
     Permitted Seller Notes and Permitted Earn-Out Debt issued by Holdings after
     the date hereof shall not exceed $20,000,000;

          (xiii)  the Borrower shall only include for any Person or business,
     division or product line acquired, 100% of audited financial statement
     based Consolidated EBITDA calculated on a Pro Forma Basis and 75% of
     personally guaranteed unaudited financial statement based Consolidated
     EBITDA calculated on a Pro Forma Basis with respect to calculations made in
     connection with the covenants contained in this Section 5.15 and Sections
     6.06 through 6.09, inclusive; and

          (xiv)   prior to the consummation of the respective Permitted
     Acquisition, the Borrower shall furnish the Agent and the Lenders an
     officer's certificate executed by the chief financial officer of Holdings,
     certifying as to compliance with the requirements of the applicable
     preceding clauses (i) through (xiii) and containing the calculations
     required by preceding clauses (v), (vii), (viii), (x), (xi) and (xii). The
     consummation of each Permitted Acquisition shall be deemed to be a
     representation and warranty by Holdings that all conditions thereto have
     been satisfied and that same is permitted in accordance with the terms of
     this Agreement, which representation and warranty shall be deemed to be a
     representation and warranty for all purposes hereunder, including, without
     limitation, Sections 3.02 and 7.

          (b)  At the time of each Permitted Acquisition involving the creation
or acquisition of a Subsidiary, not less than 100% of the capital stock of such
Subsidiary shall be directly owned by the Borrower; provided, however, for up to
one Business Day after such Permitted Acquisition, Holdings may own such
Subsidiary; and provided, further, that either Holdings or the Borrower may own
less than 100% (but more than 50%) of the capital stock or other equity or
beneficial ownership interests of Subsidiaries for which the Borrower has paid
(in the aggregate) no more than $5 million in consideration.

          (c)  The Borrower shall cause each Subsidiary which is formed to
effect, or is acquired pursuant to, a Permitted Acquisition to execute and
deliver, prior to the date of 

                                       38
<PAGE>
 
the respective Permitted Acquisition, the Subsidiaries Guaranty (or an amendment
thereto pursuant to which it shall become a guarantor thereunder) or a
substantially similar guaranty, in either case with the documentation to be in
form and substance satisfactory to the Agent.

          5.16  Subsidiary Metroplex Note.  In connection with any payment with
                -------------------------                                      
respect to the Subsidiary Metroplex Note, Holdings shall make the necessary
requests under the Equity Call Agreement in order to obtain all funds necessary
to make such payment from the shareholders of Holdings party to the Equity Call
Agreement unless the funds necessary to make such payment consist of Excluded
Public Offering Proceeds; provided, however, in the event that neither Holdings
nor the Bank Agent makes the necessary requests under the Equity Call Agreement,
then the Agent shall be entitled to make such request.

          5.17. Default on Metroplex Note.  Upon the occurrence of a default in
                -------------------------

Subsequent Commitment remains outstanding, at the request of the Agent, the
Borrower will borrow an amount equal to the Subsequent Commitment in accordance
with the terms of this Agreement and will use the proceeds of such borrowing to
pay in full the Metroplex Note.

          5.18. Corporate Separateness.  Holdings and each of its Subsidiaries
                ----------------------                                        
will take all such action as is necessary to keep the operations of each such
Person separate and apart from those of each such other Person, including,
without limitation, ensuring that all customary corporate formalities, including
the maintenance of corporate records and holding regular meetings of
shareholders and directors are followed.  None of Holdings or any of its
Subsidiaries shall take any action, or conduct its affairs in a manner, which is
likely to result in the corporate existence of Holdings or any of its
Subsidiaries being disregarded, or in the assets and liabilities of Holdings or
any of its Subsidiaries being substantively consolidated with those of Holdings
or any of its Subsidiaries in a bankruptcy, reorganization or other insolvency
proceeding.

respect to any of their respective property or assets (real or personal,
tangible or intangible), whether now owned or hereafter acquired, or sell any
such property or assets subject to an understanding or

(including sales of accounts receivable with recourse to Holdings or any of its
Subsidiaries, or assign any right to receive income or permit the filing of any
financing statement under the UCC or any other similar notice of Lien under any
similar recording or notice statute; provided, however, that the provisions of
                                     --------  -------
this Section 6.01 shall not prevent Holdings or any of its Subsidiaries from

     established in accordance with generally accepted accounting principles;

          (ii)  Liens in respect of property or assets of the Borrower or any
     Subsidiary of the Borrower imposed by law, which were incurred in the

     money, such as carriers', warehousemen's, materialmen's, mechanics' and
     landlords' liens and other similar Liens arising in the ordinary course of
     business, and (x) which do not in the aggregate materially detract from the
     value of the Borrower's or any of its Subsidiaries' property or assets or
     materially impair the use thereof in the operation of the business of the
     Borrower or the Subsidiaries of the Borrower or (y) which are being
     contested in good faith by appropriate proceedings, which proceedings have
     the effect of preventing the forfeiture or sale of the property or assets
     subject to any such Lien;

          (iii) Liens of the Borrower or the Subsidiaries of the Borrower in
     existence on the Effective Date which are listed, and the property subject

          Section 9.  The Agent.
                      --------- 

          9.01  Appointment. The Lenders hereby designate PCF as Agent to act as
                ----------- 
specified herein and in the other Loan Documents. Each Lender hereby irrevocably

                                       74
<PAGE>
 
authorizes, and each holder of any Note by the acceptance of such Note shall be
deemed irrevocably to authorize, the Agent to take such action on its behalf
under the provisions of this Agreement, the other Loan Documents and any other
instruments and agreements referred to herein or therein and to exercise such
powers and to perform such duties hereunder and thereunder as are specifically
delegated to or required of the Agent by the terms hereof and thereof and such
other powers as are reasonably incidental thereto. The Agent may perform any of
its duties hereunder by or through its officers, directors, agents or employees.

          9.02  Nature of Duties. The Agent shall have no duties or
                ----------------    
responsibilities except those expressly set forth in this Agreement and the
other Loan Documents. Neither the Agent nor any of its officers, directors,
agents, employees or affiliates shall be liable for any action taken or omitted
by it or them hereunder or under any other Loan Document or in connection
herewith or therewith, unless caused by its or their gross negligence or willful
misconduct. The duties of the Agent shall be mechanical and administrative in
nature; the Agent shall not have by reason of this Agreement or any other Loan
Document a fiduciary relationship in respect of any Lender or the holder of any
Note; and nothing in this Agreement or any other Loan Document, expressed or
implied, is intended to or shall be so construed as to impose upon the Agent any
obligations in respect of this Agreement or any other Loan Document except as
expressly set forth herein.

          9.03  Lack of Reliance on the Agent. Independently and without
                ----------------------------- 
reliance upon the Agent, each Lender and the holder of each Note, to the extent
it deems appropriate, has made and shall continue to make (i) its own
independent investigation of the financial condition and affairs of Holdings and
its Subsidiaries in connection with the making and the continuance of the Loans
and the taking or not taking of any action in connection herewith and (ii) its
own appraisal of the creditworthiness of Holdings and its Subsidiaries and,
except as expressly provided in this Agreement, the Agent shall have no duty or
responsibility, either initially or on a continuing basis, to provide any Lender
or the holder of any Note with any credit or other information with respect
thereto, whether coming into its possession before the making of the Loans or at
any time or times thereafter. The Agent shall not be responsible to any Lender
or the holder of any Note for any recitals, statements, information,
representations or warranties herein or in any document, certificate or other
writing delivered in connection herewith or for the execution, effectiveness,
genuineness, validity, enforceability, perfection, priority or sufficiency of
this Agreement or any other Loan Document or the financial condition of Holdings
or its Subsidiaries or be required to make any inquiry concerning either the
performance or observance of any of the terms, provisions or conditions of this
Agreement or any other Loan Document, or the financial condition of Holdings or
its Subsidiaries or the existence or possible existence of any Default or Event
of Default. In no event shall the Agent be required to take any action in
contravention of applicable law or if such action would cause

                                       75
<PAGE>
 
it, in its sole determination, to incur any risk or liability for which it is
not adequately indemnified for to its sole satisfaction.

          9.04  Certain Rights of the Agent. If the Agent shall request
                ---------------------------  
instructions from the Required Lenders with respect to any act or action
(including failure to act) in connection with this Agreement or any other Loan
Document, the Agent shall be entitled to refrain from such act or taking such
action unless and until the Agent shall have received instructions from the
Required Lenders; and the Agent shall not incur liability to any Person by
reason of so refraining. Without limiting the foregoing, no Lender or the holder
of any Note shall have any right of action whatsoever against the Agent as a
result of the Agent acting or refraining from acting hereunder or under any
other Loan Document in accordance with the instructions of the Required Lenders.

          9.05  Reliance. The Agent shall be entitled to rely, and shall be
                --------
fully protected in relying, upon any note, writing, resolution, notice,
statement, certificate, telex, teletype or facsimile message, cablegram,
radiogram, legal opinion, order or other document or telephone message signed,
sent or made by any Person that the Agent believed to be the proper Person, and,
with respect to all legal matters pertaining to this Agreement and any other
Loan Document and its duties hereunder and thereunder, upon advice of counsel
selected by it.

          9.06  Indemnification. To the extent the Agent is not reimbursed and
                ---------------                                                
indemnified by the Borrower, the Lenders will reimburse and indemnify the Agent,
in proportion to their respective "percentages" as used in determining the
Required Lenders, for and against any and all liabilities, obligations, losses,
damages, penalties, claims, actions, judgments, suits, costs, expenses or
disbursements of whatsoever kind or nature which may be imposed on, asserted
against or incurred by the Agent in performing its duties hereunder or under any
other Loan Document, in any way relating to or arising out of this Agreement or
any other Loan Document; provided, that no Lender shall be liable for any
                         --------                                        
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Agent's
gross negligence or willful misconduct.

          9.07  The Agent in Its Individual Capacity. With respect to its
                ------------------------------------ 
obligation to make Loans under this Agreement, the Agent shall have the rights
and powers specified herein for a "Lender" and may exercise the same rights and
powers as though it were not performing the duties specified herein; and the
term "Lenders," "Required Lenders," "holders of Notes" or any similar terms
shall, unless the context clearly otherwise indicates, include the Agent in its
individual capacity. The Agent and its Affiliates may accept deposits from, lend
money to, and generally engage in any kind of banking, trust or other business
with the Borrower and its Subsidiaries or any Affiliate thereof as if it were
not performing the duties specified herein, and may accept fees and other
consideration from

                                       76
<PAGE>
 
Holdings and its Subsidiaries for services in connection with this Agreement and
otherwise without having to account for the same to the Lenders.

          9.08  Holders. The Agent may deem and treat the payee of any Note as
                -------   
the owner thereof for all purposes hereof unless and until a written notice of
the assignment, transfer or endorsement thereof, as the case may be, shall have
been filed with the Agent. Any request, authority or consent of any Person who,
at the time of making such request or giving such authority or consent, is the
holder of any Note shall be conclusive and binding on any subsequent holder,
transferee, assignee or indorsee, as the case may be, of such Note or of any
Note or Notes issued in exchange therefor.

          9.09  Resignation by the Agent. The Agent may resign from the
                ------------------------
performance of all its functions and duties hereunder and/or under the other
Loan Documents at any time by giving fifteen Business Days' prior written notice
to the Borrower and the Lenders. Such resignation shall take effect upon the
appointment of a successor Agent pursuant to clauses (b) and (c) below or as
otherwise provided below.

          (b)   Upon any such notice of resignation, the Required Lenders shall
appoint a successor Agent hereunder or thereunder who shall be a commercial bank
or trust company reasonably acceptable to the Borrower.

          (c)   If a successor Agent shall not have been so appointed within
such 15 Business Day period, the Agent, with the consent of the Borrower, shall
then appoint a successor Agent who shall serve as Agent hereunder or thereunder
until such time, if any, as the Lenders appoint a successor Agent as provided
above.

          (d)   If no successor Agent has been appointed pursuant to clause (b)
or (c) above by the 20th Business Day after the date such notice of resignation
was given by the Agent, the Agent's resignation shall become effective and the
Lenders shall thereafter perform all the duties of the Agent hereunder and/or
under any other Loan Document until such time, if any, as the Lenders appoint a
successor Agent as provided above.

          Section 10.  Subordinated Guaranty of Holdings
                       ---------------------------------

          10.01 The Guaranty.  In order to induce the Lenders to enter into this
                ------------                                                    
Agreement and to extend credit hereunder and in recognition of the direct
benefits to be received by Holdings from the proceeds of the Loans, Holdings
hereby agrees with the Lenders as follows:  Holdings hereby unconditionally and
irrevocably guarantees as primary obligor and not merely as surety the full and
prompt payment when due, whether upon maturity, by acceleration or otherwise, of
any and all indebtedness of the Borrower to the Lenders under this Agreement and
the other Loan Documents.  If any or all of the indebtedness of the Borrower to
the Lenders becomes due and payable hereunder or under 

                                       77
<PAGE>
 
such other Loan Documents, Holdings unconditionally promises to pay such
indebtedness to the Lenders, or order of demand, together with any and all
expenses which may be incurred by the Agent or the Lenders in collecting any of
the indebtedness. The word "indebtedness" is used in this Section 10 in its most
comprehensive sense and means any and all advances, debts, obligations and
liabilities of the Borrower arising in connection with this Agreement or any
other Loan Documents, in each case, heretofore, now, or hereafter made, incurred
or created, whether voluntarily or involuntarily, absolute or contingent,
liquidated or unliquidated, determined or undetermined, whether or not such
indebtedness is from time to time reduced, or extinguished and thereafter
increased or incurred, whether the Borrower may be liable individually or
jointly with others, whether or not recovery upon such indebtedness may be or
hereafter become barred by any statute of limitations, and whether or not such
indebtedness may be or hereafter become otherwise unenforceable.

          10.02  Bankruptcy. Additionally, Holdings unconditionally and
                 ----------
irrevocably guarantees the payment of any and all indebtedness of the Borrower
to the Lenders whether or not due or payable by the Borrower upon the occurrence
of any of the events specified in Section 7.05, and unconditionally and
irrevocably promises to pay such indebtedness to the Lenders, or order, on
demand, in lawful money of the United States.

          10.03  Nature of Liability. The liability of Holdings hereunder is
                 ------------------- 
exclusive and independent of any security for or other guaranty of the
indebtedness of the Borrower whether executed by Holdings, any other guarantor
or by any other party, and the liability of Holdings hereunder shall not be
affected or impaired by (a) any direction as to application of payment by the
Borrower or by any other party, or (b) any other continuing or other guaranty,
undertaking or maximum liability of a guarantor or of any other party as to the
indebtedness of the Borrower, or (c) any payment on or in reduction of any such
other guaranty or undertaking, or (d) any dissolution, termination or increase,
decrease or change in personnel by the Borrower, or (e) any payment made to the
Agent or the Lenders on the indebtedness which the Agent or such Banks repay the
Borrower pursuant to court order in any bankruptcy, reorganization, arrangement,
moratorium or other debtor relief proceeding, and Holdings waives any right to
the deferral or modification of its obligations hereunder by reason of any such
proceeding.

          10.04  Guaranty Subordinate to Senior Indebtedness. Holdings covenants
                 ------------------------------------------- 
and agrees, and the Agent and the Lenders, by acceptance of this Holdings
Guaranty likewise covenant and agree, that, (a) to the extent and in the manner
hereinafter set forth in this Section 10.04, this Holdings Guaranty, including
pursuant to any amendment, modification, restatement or renewal thereof, is
hereby expressly made subordinated and subject in right of payment to the prior
payment in full of all Senior Debt and (b) the terms and conditions of such
subordination is for the benefit of the holders of the Senior Debt and each such
holder may enforce such subordination.

                                       78
<PAGE>
 
          10.05  Guaranty Absolute. No invalidity, irregularity or
                 ----------------- 
unenforceability of all or any part of the indebtedness guaranteed hereby or of
any security therefor shall affect, impair or be a defense to this Guaranty, and
this Guaranty shall be primary, absolute and unconditional notwithstanding the
occurrence of any event or the existence of any other circumstances which might
constitute a legal or equitable discharge of a surety or guarantor except
payment in full of the indebtedness guaranteed herein.

          10.06  Independent Obligation. The obligations of Holdings hereunder
                 ---------------------- 
are independent of the obligations of any other guarantor or the Borrower, and a
separate action or actions may be brought and prosecuted against Holdings
whether or not action is brought against any other guarantor or the Borrower and
whether or not any other guarantor the Borrower be joined in any such action or
actions. Holdings waives, to the fullest extent permitted by law the benefit of
any statute of limitations affecting its liability hereunder or the enforcement
thereof. Any payment by the Borrower or other circumstance which operates to
toll any statute of limitations as to the Borrower shall operate to toll the
statute of limitations as to Holdings.

          10.07  Authorization. Holdings authorizes the Agent and the Lenders
                 -------------  
without notice or demand to Holdings, and without affecting or impairing its
liability hereunder, from time to time to:

          (a)  change the manner, place or terms of payment of, and/or change or
     extend the time of payment of, renew, increase, accelerate or alter, any of
     the indebtedness (including any increase or decrease in the rate of
     interest thereon), any security therefor, or any liability incurred
     directly or indirectly in respect thereof, and the Guaranty herein made
     shall apply to the indebtedness as so changed, extended, renewed or
     altered;

          (b)  take and hold security for the payment of the indebtedness and
     sell, exchange, release, surrender, realize upon or otherwise deal with in
     any manner and in any order any property by whomsoever at any time pledged
     or mortgaged to secure, or howsoever securing, the indebtedness or any
     liabilities (including any of those hereunder) incurred directly or
     indirectly in respect thereof or hereof, and/or any offset thereagainst;

          (c)  exercise or refrain from exercising any rights against the
     Borrower or others or otherwise act or refrain from acting;

          (d)  release or substitute any one or more endorsers, guarantors, the
     Borrower or other obligors;

                                       79
<PAGE>
 
          (e)  settle or compromise any of the indebtedness, any security
     therefor or any liability (including any of those hereunder) incurred
     directly or indirectly in respect thereof or hereof, and may subordinate
     the payment of all or any part thereof to the payment of any
     liability(whether due or not) of the Borrower to its creditors other than
     the Lenders;

          (f)  apply any sums by whomsoever paid or howsoever realized to any
     liability or liabilities of the Borrower to the Lenders regardless of what
     liability or liabilities of Holdings or the Borrower remain unpaid;

          (g)  consent to or waive any breach of, or any act, omission or
     default under, this Agreement or any of the instruments or agreements
     referred to herein, or otherwise amend, modify or supplement this Agreement
     or any of such other instruments or agreements; and/or

          (h)  take any other action which would, under otherwise applicable
     principles of common law, give rise to a legal or equitable discharge of
     Holdings from its liabilities under this Section 10.

          10.08  Reliance. It is not necessary for the Agent or the Lenders to
                 --------     
inquire into the capacity or powers of the Borrower or its Subsidiaries or the
officers, directors, partners or agents acting or purporting to act on its
behalf, and any indebtedness made or created in reliance upon the professed
exercise of such powers shall be guaranteed hereunder.

          10.09  Subordination. Any indebtedness of the Borrower now or
                 -------------                                     
hereafter held by Holdings is hereby subordinated to the indebtedness of the
Borrower to the Agent and the Lenders, and such indebtedness of the Borrower to
Holdings, if the Agent (at the direction of the Required Lenders), after an
Event of Default has occurred, so requests, shall be collected, enforced and
received by Holdings as trustee for the Lenders and be paid over to the Lenders
on account of the indebtedness of the Borrower to the Lenders, but without
affecting or impairing in any manner the liability of Holdings under the other
provisions of this Guaranty. Prior to the transfer by Holdings of any note or
negotiable instrument evidencing any indebtedness of the Borrower to Holdings,
Holdings shall mark such note or negotiable instrument with a legend that the
same is subject to this subordination.

          10.10  Waiver. (a)  Holdings waives any right to require the Agent or
                 ------                                                         
the Lenders to (i) proceed against the Borrower, any other guarantor or any
other party, (ii) proceed against or exhaust any security held from the
Borrower, any other guarantor or any other party or (iii) pursue any other
remedy in the Agent's or the Lenders' power whatsoever.  Holdings waives any
defense based on or arising out of any defense of the 

                                       80
<PAGE>
 
Borrower, any other guarantor or any other party other than payment in full of
the indebtedness (other than payment), including, without limitation, any
defense based on or arising out of the disability of the Borrower, any other
guarantor or any other party, or the unenforceability of the indebtedness or any
party thereof from any cause, or the cessation from any cause of the liability
of the Borrower other than to the extent of payment in full of the indebtedness.
The Agent and the Lenders may, in accordance with the Loan Documents, at their
election, foreclose on any security held by the Agent or the Lenders by one or
more judicial or nonjudicial sales, whether or not every aspect of any such sale
is commercially reasonable (to the extent such sale is permitted by applicable
law), or exercise any other right or remedy the Agent and the Lenders may have
against the Borrower or any other party, or any security, without affecting or
impairing in any way the liability of Holdings hereunder except to the extent
the indebtedness has been paid. Holdings waives any defense arising out of any
such election by the Agent and the Borrower, even though such election operates
to impair or extinguish any right of reimbursement or subrogation or other right
or remedy of Holdings against the Borrower or any other party or any security.

          (b)   Except as otherwise specifically required hereunder, Holdings
waives all presentments, demands for performance, protests and notices,
including, without limitation, notices of nonperformance, notices of protest,
notices of dishonor, notices of acceptance of this Guaranty, and notices of the
existence, creation or incurring of new or additional indebtedness. Holdings
assumes all responsibility for being and keeping itself informed of the
Borrower's financial condition and assets, and of all other circumstances
bearing upon the risk of non-payment of the indebtedness and the nature, scope
and extent of the risks which Holdings assumes and incurs hereunder, and agrees
that the Agent and the Lenders shall have no duty to advise Holdings of
information known to them regarding such circumstances or risks.


          10.11 Guaranty Continuing. This Guaranty is a continuing one and all
                -------------------                                            
liabilities to which it applies or may apply under the terms hereof shall be
conclusively presumed to have been created in reliance hereon.  No failure or
delay on the part of any Lender or any holder of any Note, in exercising any
right, power or privilege hereunder shall operate as a waiver thereof, nor shall
any single or partial exercise of any right, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege.  The rights and remedies herein expressly specified
are cumulative and not exclusive of any rights or remedies which any Lender or
any subsequent holder of a Note would otherwise have.  No notice  to or demand
on Holdings in any case shall entitle Holdings to any other or further notice or
demand in similar or other circumstances or constitute a waiver of the rights of
the Lender or any holder, creator or purchaser to any other or further action in
any circumstances without notice or demand.

          10.12  Binding Nature of Guaranties.  This Guaranty shall be binding
                 ----------------------------

the Lender and their successors and assigns.

          10.13  Judgments Binding.  If claim is ever made upon any Lender or
                 -----------------                                           
any subsequent holder of a Note for repayment or recovery of any amount or
amounts received in payment or on account of any of the indebtedness and any of
the aforesaid payees repays all or part of said amount by reason of (a) any
judgment, decree or order of any court or administrative body having
jurisdiction over such payee or any of its property, or (b) any settlement or
compromise of any such claim effected by such payee with any such claimant
(including the Borrower) then and in such event Holdings agrees that any such
judgment, decree, order, settlement or compromise shall be binding upon
Holdings, notwithstanding any revocation hereof or the cancellation of any Note,
or other instrument evidencing any liability of the Borrower, and Holdings shall
be and remain liable to the aforesaid payees hereunder for the amount so repaid
or recovered to the same extent as if such amount had never originally been
received by any such payee.

          Section 11.  Subordination
                       -------------

          (a)  the holders of Senior Indebtedness shall be entitled to receive
payment in full in cash of all amounts due or to become due on or in respect of

by reason of the payment of any other Indebtedness of the Borrower being
subordinated to the payment of Subordinated Obligations (except for any such
payment or distribution (1) authorized by an unstayed, final, nonappealable

described herein) shall be paid by the liquidating trustee or agent or other
Person making such payment or distribution, whether a trustee in bankruptcy, a
receiver or liquidating trustee or otherwise, directly to the holders of all
Senior Indebtedness or their representative or representatives or to the trustee
or trustees under any indenture under which any instruments evidencing any of
such Senior Indebtedness may have been issued, ratably according to the
aggregate amounts remaining unpaid on account of the principal of, and interest
on, such Senior Indebtedness held or represented by each, to the extent
necessary to make payment in full of all such Senior Indebtedness remaining
unpaid, after giving effect to any concurrent payment or distribution to the
holders of such Senior Indebtedness; and

          (c)  in the event that, notwithstanding the foregoing provisions of
this Section 11, any Lender shall have received any such payment or distribution
of assets of the Borrower of any kind or character, whether, property or
securities, including any such payment or distribution which may be payable or
deliverable by reason of the payment of any other Indebtedness of the Borrower
being subordinated to the payment of the Subordinated Obligations (but excluding
any payment of the character described in the parenthetical clause in the
foregoing paragraph (b)) before all Senior Indebtedness is paid

                                       83
<PAGE>
 
in full or payment thereof is provided for, then and in such event such payment
or distribution shall be paid over or delivered forthwith to the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other
Person making payment or distribution of assets of the Borrower for application
to the payment of all such Senior Indebtedness remaining unpaid, to the extent
necessary to pay such Senior Indebtedness in full, after giving effect to any
concurrent payment or distribution to or for the holders of such Senior
Indebtedness.

          If, notwithstanding the provisions of this Agreement, there shall
occur any consolidation of the Borrower with, or any merger of the Borrower
into, another corporation or the liquidation or dissolution of the Borrower
following any conveyance, transfer or lease of its properties and assets
substantially as an entirety to another corporation, such consolidation, merger
or liquidation shall not be deemed a Bankruptcy Event; provided, that no other
Bankruptcy Event shall have occurred and be continuing at the time of such
consolidation, merger or liquidation.  The Bank Agent is hereby authorized to
file an appropriate claim on behalf of the Lenders if the Lenders do not file
such claim or there is not filed on behalf of the Lenders a proper proof of
claim in the form required in any Bankruptcy Event prior to thirty (30) days
before the expiration of the time to file such claim or claims.

          11.03  No Payment in Certain Circumstances.  In the event that (i) the
                 -----------------------------------                            
Borrower shall fail to pay when due (after giving effect to any applicable grace
periods), upon acceleration or otherwise, any amount or obligation with respect
to Senior Indebtedness (a "Payment Default") which Payment Default shall not
have been cured or waived, or (ii) an event of default (other than a Payment
Default) under the Senior Credit Agreement shall occur and be continuing, which
shall not have been cured or waived (a "Non-Payment Default"), and the Borrower
and the Agent receive written notice of such Non-Payment Default from either the
Bank Agent or the holders of at least a majority in aggregate principal amount
of the Senior Debt under the Senior Credit Agreement at the time outstanding (a
"Non-Payment Blockage Notice"), then no payment on account of the Subordinated
Obligations shall be made by the Borrower (x) in the case of any Payment
Default, unless and until such Senior Indebtedness shall have been paid in full
or until such Payment Default shall have been cured or waived, or (y) in the
case of any Non-Payment Default, from the earlier of the date on which the
Borrower and the Agent receive such Non-Payment Blockage Notice until the
earlier of (1) 179 days after such date and (2) the date, if any, on which the
Senior Debt under the Senior Credit Agreement is paid in full or such Non-
Payment Default is waived by the holders of such Senior Debt or otherwise cured
(a "Blockage Period"); provided, that only one Non-Payment Blockage Notice may
be given in any 360-day period.

          In the event that, notwithstanding the foregoing, the Borrower shall
make any payment to any Lender prohibited by the foregoing provisions of this
Section 11.03, 

                                      84
<PAGE>
 
then and in such event such payment shall be paid over and delivered forthwith
to the holders (or their agent or trustee) of the relevant Senior Indebtedness.
The provisions of this Section 11.03 shall not apply to any payment with respect
to which Section 11.02 would be applicable.

          11.04  Acceleration Rights; Remedies. If an Event of Default, other
                 -----------------------------
than an Event of Default under Section 7.05, shall exist at any time that any
Senior Debt under the Senior Credit Agreement shall be outstanding, no Lender
nor any other holder of the Notes nor the Agent shall take any action, judicial
or otherwise, to accelerate or collect payment on the Subordinated Obligations
or to pursue any other remedy with respect to the Subordinated Obligations prior
to the earlier of (i) the expiration of five Business Days immediately following
the receipt by the Bank Agent of notice of the occurrence of such Event of
Default from the Agent or from the holder or holders entitled to accelerate
payments on the Subordinated Obligations or (ii) acceleration of the Senior
Debt, but such action may only be taken if at the end of such period such Event
of Default has not been cured or waived; provided, that any amount received by
the Agent or any of the Lenders as a result of any acceleration permitted above
prior to payment in full in cash of the Senior Debt under the Senior Credit
Agreement shall be paid to the Bank Agent in accordance with the provisions of
this Section 11.

          11.05  Payment Otherwise Permitted. Nothing contained in this Section
                 ---------------------------
11 or elsewhere in this Agreement or in the Notes shall prevent the Borrower, at
any time except as set forth in Section 11.02 or under the conditions described
in Section 11.03, from making payments at any time of principal of and interest
on the Loans or any other amount payable by the Borrower under the Notes or this
Agreement. Notwithstanding the provisions of this Section 10, neither the Agent
nor any Lender shall be charged with knowledge of the existence of any facts,
including of the occurrence of a Payment Default, which would prohibit the
making of any payment or distribution by the Borrower or the receipt or
retention thereof by the Agent or any Lender, or the taking of any action by the
Agent or any Lender of the type referred to in Section 11.04, unless the Agent
or such Lender as the case may be, shall have received at least two Business
Day's prior written notice of such facts.

          11.06  Subrogation to Rights of Holders of Senior Indebtedness.
                 -------------------------------------------------------
Subject to, and solely effective following, the final payment in full of all
Senior Indebtedness the Lenders shall be subrogated to the rights of the holders
of Senior Indebtedness to receive payments and distributions of cash, property
and securities applicable to such Senior Indebtedness to the extent of the
payments or distributions made to the Banks, or otherwise applied to payment of,
the Senior Indebtedness pursuant to the provisions of this Section 11 until the
principal of and interest on the Loans and the Notes shall be paid in full. For
purposes of such subrogation, no payments or distributions to the holders of
Senior Indebtedness of any cash, property or securities to which the Lenders
would be entitled 

                                      85
<PAGE>
 
except for the provisions of this Section 11, and no payments over pursuant to
the provisions of this Section 11 to the holders of Senior Indebtedness by the
Lenders shall, as among the Borrower, its creditors (other than holders of
Senior Indebtedness) and the Lenders, be deemed to be a payment or distribution
by the Borrower to or on account of the Senior Indebtedness.

          11.07  Provisions Solely to Define Relative Rights. The provisions of
                 -------------------------------------------
this Section 11 are and are intended solely for the purpose of defining the
relative rights of the holders of the Notes on the one hand and the holders of
Senior Indebtedness on the other hand. Nothing contained in this Section 11 or
elsewhere in this Agreement or in the Notes is intended to or shall (i) impair,
as among the Borrower, its creditors (other than holders of Senior Indebtedness)
and the Lenders, the obligation of the Borrower, which is absolute and
unconditional, to pay to the Lenders the principal of, and premium and interest
on, and any other amount payable by the Borrower under, the Loans, the Notes or
this Agreement as and when the same shall become due and payable in accordance
with its terms; or (ii) affect the relative rights against the Borrower of the
Lenders and its creditors (other than the holders of Senior Indebtedness); or
(iii) prevent the Lenders from accelerating the Loans and exercising all other
remedies otherwise permitted by applicable law upon default under this
Agreement, subject to the rights, if any, under this Section 11 of the holders
of Senior Indebtedness (x) upon the occurrence of a Bankruptcy Event, to
receive, pursuant to and in accordance with Section 11.02, cash, property and
securities otherwise payable or deliverable to the Lenders, (y) under the
conditions specified in Section 11.03, to prevent any payment prohibited by such
Section or (z) Section 11.04.

          11.08  No Waiver of Subordination Provisions; Amendment. No right of
                 ------------------------------------------------
any present or future holder of any Senior Indebtedness to enforce subordination
as herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Borrower or by any act or failure to
act, in good faith, by any such holder, or by any non-compliance by the Borrower
with the terms, provisions, and covenants of this Agreement, regardless of any
knowledge thereof any such holder may have or be otherwise charged with. Without
in any way limiting the generality of the foregoing, the holders of Senior
Indebtedness may at any time and from time to time, without the consent of or
notice to the Lenders or any other holder of the Notes, without incurring
responsibility to the Lenders or such holders and without impairing or releasing
the subordination provided in this Section 11 or the obligations hereunder of
the Lenders and such holders to the holders of Senior Indebtedness, do any one
or more of the following: (i) change the manner, place or terms of payment or
extend the time of payment of, or renew or alter, Senior Indebtedness or any
instrument evidencing the same or any agreement under which Senior Indebtedness
is outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any
Person liable in any manner for the collection of Senior 

                                      86
<PAGE>
 
Indebtedness; and (iv) exercise or refrain from exercising any rights against
the Borrower and any other Person.

          11.09  Reliance on Judicial Order or Certificate of Liquidating Agent.
                 --------------------------------------------------------------
Upon any payment or distribution of assets of the Borrower referred to in this
Section 11, the Lenders shall be entitled to rely upon any unstayed, final,
nonappealable order or decree entered by any court of competent jurisdiction in
which a Bankruptcy Event is pending, for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of Senior
Indebtedness of the Borrower, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Section 11.

          11.10  Turnover; Miscellaneous Subordination Provisions.  (a)  If a
                 ------------------------------------------------            
distribution is made to any holder of Subordinated Obligations that because of
this Section 11 should not have been made to it, such holder shall segregate
such distribution from its other funds and property and hold it in trust for the
benefit of, and, upon written request, pay it over (in the same form as
received, with any necessary endorsement) to, the holders of Senior Indebtedness
as their interests may appear, or their agent or representative or the trustee
under the indenture or other agreement (if any) pursuant to which Senior
Indebtedness may have been issued, as their respective interests may appear, for
application (in the case of cash) to, or as collateral (in the case of non-cash
property or securities) for the payment or prepayment of, all obligations with
respect to Senior Indebtedness remaining unpaid to the extent necessary to pay
such obligations in full in accordance with their terms, after giving effect to
an concurrent payment or distribution to or for the holders of Senior
Indebtedness.

          (b)  A distribution may consist of cash, securities or other property,
by set-off or otherwise, and a payment or distribution on account of any
obligations with respect to the holders of Subordinated Obligations shall
include any redemption, purchase or other acquisition of the Subordinated
Obligations.

          (c)  For the purpose of this Section 11, all indebtedness now or
hereafter existing under the Senior Credit Agreement shall not be deemed to have
been paid in full unless the holders or owners thereof shall have received
payment in full in cash.

          (d)  The agreements contained in this Section 11 shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any of the Senior Indebtedness is rescinded or must otherwise be returned by any
holder of Senior Indebtedness upon any Bankruptcy Event of the Borrower, all as
though such payment had not been made.

                                      87
<PAGE>
 
          (e)  All rights and interests under this Agreement of the holders of
Senior Debt, and all agreements and obligations of the holders of Subordinated
Obligations and the Borrower under this Section 11, shall remain in full force
and effect irrespective of (i) any lack of validity or enforceability of the
Senior Credit Agreement, any promissory notes evidencing the Indebtedness
thereunder, or any other agreement or instrument relating thereto or to any
other Senior Debt, including, without limitation, any agreement referred to in
the definition of Senior Credit Agreement, or (ii) any other circumstance that
might otherwise constitute a defense available to, or a discharge of, any
holders of Subordinated Obligations or the Borrower.

          (f)  The provisions set forth in this Section 11 constitute a
continuing agreement and shall (i) be and remain in full force and effect until
payment in full of all Indebtedness under the Senior Credit Agreement at such
time when no Bank shall have any obligation to make advances under the Senior
Credit Agreement, (ii) be binding upon the holders of Subordinated Obligations
and the Borrower and its respective successors, transferees and assigns, and
(iii) inure to the benefit of, and be enforceable directly by, each of the
holders of Senior Indebtedness and their respective successors, transferees and
assigns.

                 -------
notices and other communications provided for hereunder shall be in writing

following delivery to an overnight courier, as the case may be, or sent by telex
or facsimile device, except that notices and communications to the Agent shall

          12.04  Benefit of Agreement. This Agreement shall be binding upon and
                 --------------------
inure to the benefit of and be enforceable by the respective successors and
assigns of the parties hereto; provided, however, that no Loan Party may assign
                               --------  -------
or transfer any of its rights, obligations or interest hereunder or under any
other Loan Document without the prior written consent of the Lenders; and

- --------  -------
participations in its rights hereunder, such Lender shall remain a "Lender" for

Loans hereunder except as provided in Section 12.04(b)) and the transferee,
assignee or participant, as the case may be, shall not constitute a "Lender"
hereunder; and provided, further, that no Lender shall transfer or grant any
               --------  -------
participation under which the participant shall have rights to approve any
amendment to or waiver of this Agreement or any other Loan Document except to
the extent such amendment or waiver would: (i) extend the final scheduled
maturity of any Loan or Note in which such participant is participating, or
reduce the rate or extend the time of payment of interest (except in connection
with a waiver of applicability of any post-default increase in interest rates)
or reduce the principal amount thereof over the amount thereof then in effect
(it being understood that waivers or modifications of conditions precedent,
covenants, Defaults or Events of Default or of a mandatory repayment shall not
constitute a change in the terms of such participation), or (ii) consent to the
assignment or transfer by or a release of the Borrower or any Subordinated
Guarantor of any of its rights and obligations under this Agreement or any

                                      90
<PAGE>
 
other Loan Document other than, in the case of any Subordinated Guaranty, as
otherwise provided therein. In the case of any such participation, the
participant shall not have any rights under this Agreement or any of the other
Loan Documents (the participant's rights against such Lender in respect of such
participation to be those set forth in the agreement executed by such Lender in
favor of the participant relating thereto) and all amounts payable by any Loan
Party hereunder and thereunder shall be determined as if such Lender had not
sold such participation.

          (b)  Notwithstanding the foregoing, any Lender (or any Lender together
with one or more other Lenders) may assign all or a portion of its outstanding
principal amount of Loans to one or more Eligible Transferees each of which
assignees shall become a party to this Agreement as a Lender by execution of an
assignment and assumption agreement substantially in the form of Exhibit J
(appropriately completed); provided that: (i) at such time Schedule I shall be
                           --------
deemed modified to reflect the outstanding Loans of such new Lender and of the
existing Lenders; (ii) new Notes will be issued, at the Borrower's expense, to
such new Lender and to the assigning Lender upon the request of such new Lender
or assigning Lender, such new Notes to be in conformity with the requirements of
Section 1.01 (with appropriate modifications) to the extent needed to reflect
the revised outstanding Loans; (iii) the consent of the Agent shall be required
in connection with any such assignment pursuant to this Section 12.04(b)(which
consent shall not be unreasonably withheld or delayed); and (iv) the Agent shall
receive at the time of each such assignment, from the assigning Lender, the
payment of a non-refundable assignment fee of $3,500. No transfer or assignment
under this Section 12.04(b) will be effective until recorded by the Agent on the
Register pursuant to Section 5.13. At the time of each assignment pursuant to
this Section 12.04(b) to a Person which is not already a Lender hereunder and
which is not a United States person (as such term is defined in Section
7701(a)(30) of the Code) for Federal income tax purposes, the respective
assignee Lender shall provide to the Borrower and the Agent the appropriate
Internal Revenue Service Forms (and, if applicable, a Section 2.04(b)(ii)
Certificate) required by Section 2.04(b). The Agent shall provide notice to the
Borrower of any such assignment effected pursuant to this Section 12.04(b);
provided, that the failure to give such notice shall not prohibit, affect or
- --------
otherwise impair any such assignment.

          12.05  No Waiver; Remedies Cumulative. No failure or delay on the part
                 ------------------------------
of the Agent or any Lender or any holder of any Note in exercising any right,
power or privilege hereunder or under any other Loan Document and no course of
dealing between Holdings or any of their Subsidiaries and the Agent or any
Lender or the holder of any Note shall operate as a waiver thereof; nor shall
any single or partial exercise of any right, power or privilege hereunder or
under any other Loan Document preclude any other or further exercise thereof or
the exercise of any other right, power or privilege hereunder or thereunder. The
rights, powers and remedies herein or in any other Loan Document expressly
provided are cumulative and not exclusive of any rights, powers or remedies

                                      91
<PAGE>
 
which the Agent or any Lender or the holder of any Note would otherwise have. No
notice to or demand on the Borrower or any of their Subsidiaries in any case
shall entitle any such Person to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the Agent
or any Lender or the holder of any Note to any other or further action in any
circumstances without notice or demand.

          12.06  Payments Pro Rata. Except as otherwise provided in this
                 -----------------
Agreement, the Agent agrees that promptly after its receipt of each payment from
or on behalf of the Borrower or any Subordinated Guarantor in respect of any
Obligations hereunder, it shall distribute such payment to the Lenders pro rata
                                                                       --------
based upon their respective shares, if any, of the Obligations with respect to
which such payment was received.

          (b)  Each of the Lenders agrees that, if it should receive any amount
hereunder (whether by voluntary payment, by realization upon security, by the
exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Loan Documents, or otherwise),
which is applicable to the payment of the principal of, or interest on, the
Loans, of a sum which with respect to the related sum or sums received by other
Lenders is in a greater proportion than the total of such Obligations then owed
and due to such Lender bears to the total of such Obligations then owed and due
to all of the Lenders immediately prior to such receipt, then such Lender
receiving such excess payment shall purchase for cash without recourse or
warranty from the other Lenders an interest in the Obligations to such other
Lenders in such amount as shall result in a proportional participation by all
the Lenders in such amount; provided, that if all or any portion of such excess
                            --------                                           
amount is thereafter recovered from such purchasing Lender, such purchase shall
be rescinded and the purchase price restored to the extent of such recovery, but

                   RESTATED AND AMENDED STOCKHOLDER AGREEMENT
                   ------------------------------------------
                                        

     THIS STOCKHOLDER AGREEMENT (this "Agreement") is made and entered into as
of this _____ day of ____________, 1997, by and among PHYSICIAN HEALTH
CORPORATION, a Delaware corporation (the "Company"), SARAH C. GARVIN, HOWARD E.
FAGIN, Ph.D., H. THOMAS SCOTT, JULIE RAWLS MOORE, and SHAMUS HOLT (collectively,
the "Stockholders" and individually, a "Stockholder").

                              W I T N E S S E T H:
                              - - - - - - - - - - 

     WHEREAS, the Company and the Stockholders desire to designate 300,000
shares issued to each Stockholder restricted stock (the "Shares"), subject to
the vesting and other provisions contained herein.

     NOW, THEREFORE, in consideration of the premises and mutual covenants and
agreements contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties hereto
agree as follows:

                                   ARTICLE I
                                   ---------
                                    VESTING
                                    -------
                                        
     1.1  Vesting Schedule.  As of the date of this Agreement, twenty-five
          ----------------                                                
percent (25%) of each Stockholder's Shares have vested.  Of the remaining
seventy-five percent (75%) (the "Remaining Shares"), subject to each Stockholder
remaining a full-time employee of the Company and continuing in such employment
throughout the vesting period, twenty-five percent (25%) of the Remaining Shares
shall vest on January 30, 1997, and twenty-five percent (25%) of the Remaining
Shares vesting on January 30, 1998, January 30, 1999, and January 30, 2000,
respectively.

     1.2  Effects of Vesting.  Those Shares that have vested pursuant to Section
          ------------------                                                    
1.1 above shall thereafter be released from the restrictions contained in this
Agreement.

     1.3  Termination of Employment.  In the event the employment of any
          -------------------------                                     
Stockholder is terminated due to death or Disability prior to January 30, 2000,
all unvested Shares issued in the name of such Stockholder shall immediately
vest.  For purposes of this Agreement, "Disability" shall be defined as a
<PAGE>
 
Stockholder becoming mentally or physically unable to perform his or her usual
employment duties for 180 days in any twelve (12) month period.

     1.4  Termination of Employment Not Due to Death or Disability.  In the
          --------------------------------------------------------         
event the employment of any Stockholder is terminated other than due to death or
Disability prior to January 30, 2000, a portion of the Stockholder's unvested
Shares equal to the amount of Shares that would have vested under Section 1.1
for the twelve (12) month period ending on the subsequent January 30 multiplied
by a fraction, the numerator of which is the number of days elapsed since the
last January 30 and the denominator of which is 365, will vest as of the date of
termination.

     1.5  Acceleration Upon a Change of Control.  Notwithstanding any other term
          -------------------------------------                                 
or condition contained herein, immediately prior to a "Change of Control" of the
Company, all unvested Shares shall immediately vest and each Stockholder shall
be the record and beneficial owner of all such Shares without regard to the
vesting schedule contained in Section 1.1 hereof or any other restrictions
contained in this Agreement.  For the purposes of this Agreement, the term
"Change of Control" means the merger, consolidation or sale of the Company with
or to any other entity if the Company is not the surviving entity, or the sale
of all or substantially all of the assets of the Company.

                                   ARTICLE II
                                   ----------
                                ESCROW OF SHARES
                                ----------------

     2.1  Establishment of Escrow.  By execution of this Agreement, each
          -----------------------                                       
Stockholder appoints Mr. Scott, in his capacity as an officer of the Company, as
escrow agent (the "Escrow Agent") to hold the Shares on behalf of and as a
convenience to each Stockholder with the same force and effect as if such Shares
had been delivered by the Company to each Stockholder and subsequently delivered
by such Stockholder to the Escrow Agent.  The Escrow Agent shall hold the Shares
for the benefit of each Stockholder pursuant to the terms of this Agreement
pending vesting or acceleration.

     2.2  Delivery of Shares.  Upon the complete vesting of all Shares subject
          ------------------                                                  
to the terms of this Agreement, the Escrow Agent shall deliver to each
Stockholder the stock certificate issued by the Company in such Stockholder's
name evidencing the Shares.  Upon the request of any Stockholder, the Escrow
Agent shall cause to be delivered to such Stockholder a stock certificate
representing those shares that have particularly vested pursuant to Section 1.1
hereof.

     2.3  Voting Rights.  Each Stockholder shall have the right to vote the
          -------------                                                    
Shares being held by the Escrow Agent on behalf of such Stockholder or direct
the Escrow Agent in writing as to the exercise of his or her voting rights with
respect to such Shares, and the Escrow Agent shall comply with any such
directors so received.  In the absence of such directions, the Escrow Agent
shall not vote any such Shares held in escrow, other than those Shares held by
the Escrow Agent in his individual capacity.

     2.4  Effect of Final Delivery.  The terms of this Article II shall continue
          ------------------------                                              
in full force and effect until the Escrow Agent has delivered or caused to be
canceled all of the Shares pursuant to the terms of this Agreement.  After all
of the Shares have been so delivered or canceled, all rights, duties and
obligations of the respective parties under this Article II shall terminate.

     2.5  Successor Escrow Agent.  Upon the resignation of the Escrow Agent, the
          ----------------------                                                
Company has the right to appoint any other officer of the Company as successor

                                      -2-
<PAGE>
 
Escrow Agent.  The Company shall also have the right to remove the Escrow Agent
or any successor thereof, with or without cause, at any time and from time to
time.

                                  ARTICLE III
                                  -----------
                                 MISCELLANEOUS
                                 -------------
                                        
     3.1  Termination of Prior Stockholder Agreement.  This Agreement supersedes
          ------------------------------------------                            
the Stockholders' Agreement dated October 6, 1995, as amended on December 28,
1995, by and among the Stockholders.

     3.2  Specific Performance.  In any action or proceeding to specifically
          --------------------

or proceeding is brought hereby waives the claim or defense therein that the
plaintiff or claimant has an adequate remedy at law, and such person shall not
urge in any such action or proceeding the claim or defense that such remedy at
law exists.  The provisions of this Article 4.1, however, shall not prevent any
party from seeking a remedy at law in connection with any breach of this
Agreement.

     3.3  Notices.  Any and all notices, designations, consents, offers,
          -------                                                       
acceptances, or any other communications provided for in this Agreement shall be
given in writing by personal delivery or by registered or certified mail which
shall be addressed, in the case of the Company, to its principal office, and in
the case of a Stockholder to his or her principal office or such other address
as may be designated by such Stockholder.

     3.4  Severability of Provisions.  If any one or more of the provisions of
          --------------------------                                          
this Agreement shall be determined to be invalid, illegal, or unenforceable in
any respect for any reason, the validity, legality, and enforceability of any
such provision in every other respect and of the remaining provisions of this
Agreement shall not be impaired in any way.

     3.5  Amendments.  No change, amendment, or modification of this Agreement
          ----------                                                          
shall be valid unless it is in writing and signed by all the parties hereto.

     3.6  Legend on Stock Certificates.  Upon the execution of this Agreement,
          ----------------------------                                        
the certificates representing the Shares subject hereto shall be surrendered to

legends) substantially as follows:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
          INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933 (THE "ACT") OR ANY STATE SECURITIES LAW OR REGULATION.

          THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
          RESTRICTIONS ON TRANSFERABILITY CONTAINED IN A STOCKHOLDER AGREEMENT

                                      -3-
<PAGE>
 
          DATED THE 6th DAY OF OCTOBER, 1995, BETWEEN AND AMONG THE PARTIES

          EXCEPT IN ACCORDANCE WITH SUCH AGREEMENT.

After endorsement, the certificates shall be returned to the Escrow Agent who
shall, subject to the terms of this Agreement, hold the certificates for the
benefit of each Stockholder.

     3.7  Waivers.  Nothing contained in this Agreement shall prevent the waiver
          -------                                                               
of the provisions of this Agreement by the parties hereto.  No party to this
Agreement, however, shall be deemed to have waived any of its rights under this
Agreement unless such waiver shall be in writing and signed by such party.  A
waiver on any one occasion shall not be construed as a bar or waiver of any
right on any future occasion.

     3.8  Counterparts.  This Agreement may be executed in any number of
          ------------

constitute one and the same instrument.

     3.9  Benefits.  All of the terms, covenants, agreements and conditions
          --------                                                         
contained in this Agreement shall be binding upon and . . . to the benefit of
all of the parties hereto, and their respective heirs, executors,
administrators, successors as assigned.

     3.10  Governing Law.  This Agreement shall be governed by and construed and
           -------------                                                        
enforced in accordance with the laws of the State of Georgia.

     3.11  Conflict with Bylaws.  In the event of any conflict between the terms
           --------------------                                                 
and provisions of this Agreement and the terms and provisions of the Bylaws of
the Company, the terms and provisions of this Agreement shall control.

     3.12  Applicability of Laws.  Any transfer of Shares made pursuant to and
           ---------------------

             NON-COMPETITION AND NON-DISCLOSURE FORM OF AGREEMENT
             ----------------------------------------------------

     In consideration and as a condition of my employment or continued
employment by Physician Health Corporation (the "Company"), I hereby agree with
the Company as follows:

     1.   I covenant and agree that for so long as I am employed by the Company
and for a two (2) year period thereafter, I will not, without the prior written
consent of the Company, directly or indirectly, within the metropolitan
statistical service areas identified on Exhibit A attached hereto (i) provide as
a manager, employee, officer or consultant any services of the type included in
my employment duties described below for any medical management services company
which develops or manages physician networks or provides management or contract
negotiation services to physician practices or (ii) solicit or attempt to
solicit any employee of the Company either to work for me personally or on
behalf of any other person or entity.  The parties acknowledge that this
Agreement may be amended from time to time by substituting a new Exhibit A to
expand the geographic scope of the restrictions contained in this Article 3.1 to
include each of the new markets in which the Company is then doing business.
For purposes of this section, my employment duties shall include _______________
________________________________________________________________________________
Notwithstanding the foregoing, if my employment is terminated "without cause,"
then the restrictions contained in clause (i) above shall terminate.  For
purposes of this paragraph, termination "without cause" shall mean termination
of my employment for any reason other than resignation, death, disability (as
such term is defined in the Amended and Restated Stockholder Agreement of even
date herewith), conviction of a felony or violation of this Agreement.

     2.   I will not at any time, whether during or after the termination of my
employment, reveal to any person or entity any of the trade secrets or
confidential information concerning the organization, business or finances of
the Company or of any third party which the Company is under an obligation to
keep confidential (including but not limited to trade secrets or confidential
information respecting inventions, products, designs, methods, know-how,
techniques, systems, processes, software programs, works of authorship, customer
lists, projects, plans and proposals), except as may be required in the ordinary
course of performing my duties as an employee of the Company, and I shall keep
secret all matters entrusted to me and shall not use or attempt to use any such
information in any manner which may injure or cause loss or may be calculated to
injure or cause loss whether directly or indirectly to the Company.

     Further, I agree that during my employment I shall not make, use or permit
to be used any notes, memoranda, reports, lists, records, drawings, sketches,
specifications, software programs, data, documentation or other materials of any
nature relating to any matter within the scope of the business of the Company or
concerning any of its dealings or affairs otherwise than for the benefit of the
Company.  I further agree that I shall not, after the termination of my
employment, use or permit to be used any such notes, memoranda, reports, lists,
records, drawings, sketches, specifications, software programs, data,
documentation or other materials, it being agreed that all of the foregoing
shall be and remain the sole and exclusive property of the Company and that
immediately upon the termination of my employment I shall deliver all of the
foregoing, and all copies thereof, to the Company, at its main office.

     3.   If at any time or times during my employment, I shall (either alone or
with others) make, conceive, create, discover or reduce to practice any
invention, modification, discovery, design, development, improvement, process,
software program, work of authorship, documentation, formula, data, technique,
know-how, secret or intellectual property right whatsoever or any interest
therein (whether or not patentable or registrable under copyright, trademark or
similar statutes or subject to analogous protection) (herein called
"Developments") that (a) relates to the business of the Company or any customer
of or supplier to the Company or any of the products or services being
developed, manufactured or sold by the Company or which may be used in relation
therewith, (b) results from tasks assigned me by the Company or (c) results from
the use of premises or personal property (whether tangible or intangible) owned,
leased or contracted for by the Company, such Developments and the benefits
thereof 

                                                                          Page 1
<PAGE>
 
are and shall immediately become the sole and absolute property of the Company
and its assigns, and I shall promptly disclose to the Company (or any persons
designated by it) each such development and, as may be necessary to ensure the
Company's ownership of such Developments, I hereby assign any rights including,
but not limited to, any copyrights and trademarks) I may have or acquire in the
Developments and benefits and/or rights resulting therefrom to the Company and
its assigns without further compensation and shall communicate, without cost or
delay, and without disclosing to others the same, all available information
relating thereto (with all necessary plans and models) to the Company.

     Upon disclosure of each Development to the Company, I will, during my
employment and at any time thereafter, at the request and cost of the Company,
sign, execute, make and do all such deeds, documents, acts and things as the
Company and its duly authorized agents may reasonably require:

     (a)  to apply for, obtain, register and vest in the name of the Company
          alone (unless the Company other-wise directs) letters patent,
          copyrights, trademarks or other analogous protection in any country
          throughout the world and when so obtained or vested to renew and
          restore the same; and

     (b)  to defend any opposition or other administrative proceedings in 
          respect of such applications and any opposition proceedings or
          petitions or applications for cancellation or revocation of such 
          letters patent, copyright or other analogous protection.

     In the event the Company is unable, after reasonable effort, to secure my
signature on any letters patent, copyright or trademark registration
applications or other documents regarding any legal protection relating to a
Development, whether because of my physical or mental incapacity or for any
other reason whatsoever, I hereby irrevocably designate and appoint the Company
and its duly authorized officers and agents as my agent and attorney-in-fact, to
act for and in my behalf and stead to execute and file any such application or
applications or other documents and to do all other lawfully permitted acts to
further the prosecution and issuance of letters patent, copyright or trademark
registrations or other legal protection thereon with the same legal force and
effect as if executed by me.

     4.   I agree that any breach of this Agreement by me will cause irreparable
damage to the Company and that in the event of such breach the Company shall
have, in addition to any and all remedies of law, the right to an injunction,
specific performance or other equitable relief to prevent the violation of my
obligations hereunder.

     5.   I understand that this Agreement does not create an obligation on the
Company or any other person or entity to continue my employment.

     6.   I represent that the Developments identified in the pages, if any,
attached hereto comprise all the unpatented and unregistered copyrightable
Developments which I have created, made or conceived prior to my employment by
the Company, which Developments are excluded from this Agreement.  I understand
that it is only necessary to list the title and purpose of such Developments but
not details thereof.

     I further represent that my performance of all of the terms of this
Agreement and as an employee of the Company does not and will not breach any
agreement to keep in confidence proprietary information acquired by me in
confidence or in trust prior to my employment by the Company.  I have not
entered into, and I agree will not enter into, any agreement either written or
oral in conflict herewith.

     7.   Any waiver by the Company of a breach of any provision of this
Agreement shall not operate or be construed as a waiver of any subsequent breach
of such provision or any other provision hereof.

     8.   I hereby agree that each provision herein shall be treated as a
separate and

                                                                          Page 2
<PAGE>
 
independent clause, and the unenforceability of any one clause shall in no way
impair the enforceability of any of the other clauses herein.  Moreover, if one
or more of the provisions contained in this Agreement shall for any reason be
held to be excessively broad as to scope, activity, subject or otherwise so as
to be unenforceable at law, such provision or provisions shall be construed by
the appropriate judicial body by limiting, or reducing it or them, so as to be
enforceable to the maximum extent compatible with the applicable law as it shall
then appear.

     9.   My obligations under this Agreement shall survive the termination of
my employment regardless of the manner of such termination and shall be binding
upon my heirs, executors, administrators and legal representatives.

     10.  The term "Company" shall include Physician Health Corporation and any
of its subsidiaries, subdivisions or affiliates.  The Company shall have the
right to assign this Agreement to its successors and assigns, and all covenants
and agreements hereunder shall inure to the benefit of and be enforceable by
said successors or assigns.

     11.  This Agreement shall be governed by and construed in accordance with
the laws of the State of Georgia.

     IN WITNESS WHEREOF, the undersigned has executed this Agreement as a sealed
instrument as of the 28th day of December, 1995.
