                               PROSPECTUS SUMMARY

               The following summary is qualified in its entirety by the more
     detailed information and the Financial Statements and notes thereto
     appearing elsewhere in this Prospectus, including the information under
     "Risk Factors."

                                  The Company

               Physicians Quality Care, Inc. ("PQC" or the "Company") provides
     practice management services for multi-specialty medical practice groups.
     The Company's objective is to establish networks of primary and specialty
     care physicians and related diagnostic and therapeutic support services
     which can provide comprehensive healthcare services in targeted geographic
     areas.

               PQC was incorporated in March 1995 as a Delaware corporation.
     The Company's executive offices are located at 950 Winter Street, Suite
     2410, Waltham, Massachusetts 02154 and its telephone number is (617) 890-
     5560.

               PQC's strategy has four central elements:

     .  developing economies of scale and geographic penetration by affiliating
        with large numbers of qualified physicians;

     .  assisting the affiliated practices in providing cost-effective
        healthcare to special populations;

     .  building comprehensive local healthcare networks by developing
        contractual or strategic relationships with providers of, or eventually
        itself providing, a full continuum of health care services in the
        community; and

     .  improving practice performance by seeking to maximize the value of each
        physician encounter.

       The Company believes that this strategy will enable it to generate
increased demand for the services and capabilities of its affiliated physicians,
treat patients in lower cost settings and negotiate favorable managed care
contracts. The Company intends to achieve growth through the recruitment of
additional physicians, the expansion of managed care relationships and the
development of contractual or strategic relationships with providers of
ancillary services.

       The core of PQC's proposed integrated healthcare delivery system is its
affiliation with groups of physicians who enter into long-term management
agreements with the Company. The Company assumes responsibility for non-medical
aspects of an affiliated physician's practice and focuses its efforts on
increasing revenues and improving operating margins, implementing management
information systems and negotiating managed care contracts. The physicians
remain responsible for, among other things, the medical, professional and
ethical aspects of their practices. By affiliating with the Company, physicians
have increased opportunity to access capital, continue to participate in the
profitability of their individual practices and, through stock ownership, share
a financial interest in the overall performance of the Company.

       General Affiliation Model. Although the details of each affiliation
transaction may differ, the Company has developed a general affiliation model
designed to capture the benefits of integration while preserving significant
physician autonomy (the "General Affiliation Model"). In the General Affiliation
Model, physicians initially affiliating with the Company in each geographic area
become stockholders of the Company and transfer their practices by mergers or
asset sales to a newly-formed professional

                                       4
<PAGE>
 
     corporation or professional association permitted to practice medicine
     under applicable law (each, an "Affiliated Group").  These physicians,
     along with other physicians in that geographic area who subsequently become
     part of an Affiliated Group and become stockholders of the Company
     (collectively, the "Stockholder Physicians"), execute multi-year employment
     agreements (each, an "Employment Agreement") with the Affiliated Group at
     the time that they transfer their practice assets.  The Affiliated Group,
     in turn, enters into a 40-year agreement (a "Services Agreement") with the
     Company pursuant to which the Company agrees to provide the physicians in
     the Affiliated Group with comprehensive management services in exchange for
     a fee.  As consideration for transferring their practices to and becoming
     employed by the Affiliated Group, Stockholder Physicians receive shares of
     the Company's Class A Common Stock, $.01 par value (the "Class A Common
     Stock") and in some cases cash, the amount of which is negotiated on an
     individual basis between each Stockholder Physician and the Company.
     Physicians who are not stockholders of the Company may also be employed by
     the Affiliated Group.

       The Employment Agreements with the Stockholder Physicians contain certain
     restrictive covenants, including covenants relating to noncompetition,
     confidentiality and nonsolicitation of employees. Each Employment Agreement
     generally is terminable by the Affiliated Group with respect to any
     individual Stockholder Physician upon the death or disability of such
     Stockholder Physician or upon the occurrence of certain events that either
     interfere with the ability of such Stockholder Physician to practice
     medicine or significantly diminish the value of such Stockholder
     Physician's affiliation to the Affiliated Group.  Each Stockholder
     Physician may terminate his or her Employment Agreement under certain
     circumstances, including without cause upon six months notice to the
     Affiliated Group.

       Established Affiliations.  The Company is in the early stages of its
     development.  The Company has completed affiliation transactions with (i)
     thirty-nine (39) physicians in the Springfield, Massachusetts area who
     transferred their practices to, and became employees of, a newly formed
     Massachusetts professional corporation, Medical Care Partners, P.C. (the
     "Springfield Affiliated Group"), that has a long-term Services Agreement
     with PQC and (ii) fifty-nine (59) physicians in the greater Baltimore-
     Annapolis, Maryland area who transferred their practices to, and became
     employees of, a newly formed Maryland professional association, Flagship
     Health, P.A. (the "Flagship Affiliated Group"), that also has a long-term
     Services Agreement with PQC.  The physicians in the Springfield Affiliated
     Group and Flagship Affiliated Group remain in their pre-affiliation
     locations offering their patients the continuity and convenience of
     decentralized offices.  Laboratory and administrative services are provided
     on a centralized basis, however, thereby providing the Company with the
     potential for economies of scale in purchasing and other administrative
     efficiencies.

       The physicians in the Springfield Affiliated Group treat patients in
     western Massachusetts and northern Connecticut.  Twenty-four (24) of the
     physicians are engaged in primary care practices and fifteen (15) are
     engaged in specialist practices including pulmonology, cardiology,
     oncology, infectious diseases, rheumatology and gastroenterology.  During
     1996, the practices combined into the Springfield Affiliated Group
     generated approximately $16.5 million in patient revenue.  The physicians
     in the Flagship Affiliated Group serve patients in the Baltimore-Annapolis,
     Maryland area.  Forty-one (41) of the Flagship physicians are engaged in
     primary care practices, including twenty (20) physicians with pediatric
     practices.  Eighteen (18) of the Flagship physicians are engaged in
     specialist practices, including hematology, cardiology, oncology,
     infectious diseases, rheumatology, gastroenterology and neurology.  The
     practices combined into the Flagship Affiliated Group generated
     approximately $25 million in patient revenue in 1996.

Stock, $.01 par value per share (the "Class B-1 Common Stock") and Class B-2
Common Stock, $.01 par value per share (the "Class B-2 Common Stock," and
together with the Class B-1 Common Stock, the "Class B Common Stock"). The
number of shares to be outstanding after the offering does not include any
shares of Class A or Class B Common Stock that may be issued by the Company to
finance its operations or cash payments in Affiliations or shares issuable
pursuant to outstanding options or warrants. Such sources of equity financing
may include certain institutional funds affiliated with Bain Capital, Inc. that
have entered into a Stock Purchase Agreement with the Company, pursuant to which
the Company, subject to certain conditions, may sell an additional 8,000,000
shares of Class B Common Stock to certain institutional investors affiliated
with Bain Capital, Inc. See "Business -- The Bain Financing." On a fully diluted
basis, assuming exercise of all outstanding warrants and options, and the
issuance of shares under certain earn-out agreements, 40,800,157 shares of Class
A and Class B Common Stock were outstanding on March 31, 1997.

                                     RISK FACTORS



       In evaluating the Company and its business, prospective investors should
carefully consider the following risk factors, in addition to the other
information contained elsewhere in this Prospectus.

Lack of Operating History; History of Operating Losses



       The Company was formed in March 1995, the first group of physicians
affiliated with the Company in August 1996 and a majority of the current
physicians affiliated with the Company in December 1996. Accordingly, the
Company's historical financial condition and results of operations should not be
relied upon in making an investment decision. For the period from March 20, 1995
(inception) to December 31, 1995, the Company recorded a net loss of $2,082,264
and for the year ended December 31, 1996, the Company recorded a net loss of
$4,973,188. The Company expects to incur operating losses for at least the
immediate future and to fund such operating losses through the issuance of
additional equity and debt securities. See "-- Need for Substantial Additional
Capital." There can be no assurance that the Company will achieve or maintain
profitability.

Need for Substantial Additional Capital

       The Company will require substantial capital resources to obtain the
necessary scale to become profitable and to fulfill its business plan.
Additional funds will be required to fund the acquisition, integration,
operation and expansion of affiliated practices, capital expenditures including
the development of the information systems to manage such practices, operating
losses and general corporate purposes. As of March 31, 1997, the Company has
satisfied its capital requirements through the issuance of $10 million of Class
B Common Stock to affiliates of Bain Capital, Inc. ("Bain Capital") pursuant to
a contractual arrangement with the Company providing for the purchase of up to
$30 million of Class B Common Stock (the "Bain Financing"), private offerings of
Class A Common Stock and a $3.5 million line of credit with Banker's Trust
Company ("Banker's Trust") as Agent, and the lenders from time to time a party
thereto (the "Credit Agreement"). The Company expects that the capital that
remains available under the Bain Financing and the Credit Agreement will be
sufficient, depending upon the Company's operating results and the consideration
paid in connection with the Affiliations, to satisfy the Company's projected
capital requirements for the next two years. To date, a significant portion of
the consideration paid in affiliation transactions has been in the form of Class
A Common Stock. If the percentage of cash required to finance future affiliation
transactions increases significantly, the Company's capital requirement will
also significantly increase. Each of the Bain Financing and the Credit Agreement
has significant financial and other conditions to their continued availability
(and in the case of the Credit Agreement to avoid a default) and there can be no
assurance that such conditions will be satisfied when capital is sought. The
Company's ability to meet the financial conditions is dependent upon a
significant increase in revenues and income from future affiliation transactions
and improved productivity of the Springfield and Flagship Affiliated Groups. The
Bain Financing also restricts the sources of capital available to the Company
without the consent of the Bain Investors. There can also be no assurance that
the Company will be able to refinance the Credit Agreement when the outstanding
balance becomes due in January 1998. See "Business -- The Bain Financing" and
"Business -- The Credit Agreement." Except for the Bain Financing and the Credit
Agreement, the Company has no committed external sources of capital. With the
consent of the director elected by the stockholders of the Class B-1 Common
Stock (the "Class B-1 Director") and the director elected by the stockholders of
the Class B-2 Common Stock (the "Class B-2 Director," and together with the
Class B-1 Director the "Class B Directors"), the Company may obtain additional
financing through external borrowings or the issuance of additional securities,
which could have an adverse effect on the value of the shares of Common Stock
held by the then existing stockholders. See "-- Dilution." There can be no
assurance that the Class B Directors will approve such capital raising
activities or that the Company will be able to raise additional capital when
needed on satisfactory terms or at all. The failure to obtain additional
financing when needed and on appropriate terms could have a material adverse
effect on the Company.

Absence of Trading Market for Common Stock

       No trading market for the Common Stock of the Company currently exists.
The Common Stock is not listed on a stock exchange or traded through the
National Association of Securities Dealers, Inc. There can be no assurance that
a public market in the Common Stock will develop in the future and the Company
does not expect such a market to develop until such time, if any, that the
Company completes a public offering of its securities other than to Stockholder
Physicians. Also, the Bain Financing requires that most current and all future
stockholders of the Company become parties to a Stockholders Agreement dated as
of August 30, 1996 (the "Stockholders Agreement"), which agreement, among other
things, contains provisions which significantly limit the transferability of the
Class A Common Stock and provide the Company with a right to purchase Class A
Common Stock from Stockholder Physicians who are parties to such Stockholders
Agreement upon their termination of employment. Consequently, an investment in
the Common Stock should only be considered as a long-term investment and is
extremely illiquid. Stockholders will be required to make their own judgment as
to the value of their shares without the benefit of an independent market price.
In circumstances where the Company is entitled to repurchase the Common Stock of
a Physician Stockholder upon death or termination of the Physician Stockholder's
employment by an Affiliated Group or the right of the Physician Stockholders to
sell the Common Stock to the Company upon a Physician Stockholder's death, the
fair market value of the Common Stock, if a public market has not yet developed,
will be determined by the Board of Directors of the Company. See "Description of
Capital Stock --Stockholders Agreement."

Risk that Future Affiliation Transactions Will Not Be Consummated; Costs of
Affiliation Transactions

       There can be no assurance that any future affiliation transactions will
be consummated. There is no assurance that the Company would be able to use the
shares registered in this offering to affiliate with additional medical
practices on acceptable terms. In consummating these future affiliation
transactions, the Company will rely upon certain representations, warranties and
indemnities made by sellers with respect to the affiliation transaction, as well
as its own due diligence investigation. There can be no assurance that such
representations and warranties will be true and correct, that the Company's due
diligence will uncover all material adverse facts relating to the operations and
financial condition of the affiliated medical practices or that all of the
conditions to the Company's obligations to consummate these future affiliations
will be satisfied. Any material misrepresentations could have a material adverse
effect on the Company's financial condition and results of operations.

       The Company has incurred significant accounting, legal and other costs in
developing its affiliation structure and completing its initial affiliation
transactions. The Company's ability to enter into affiliation transactions with
a significant number of physicians and to achieve positive cash flow will be
adversely affected unless it is able to reduce the expenses associated with
future transactions. There can be no assurance that the Company will be able to
reduce transaction costs on a per affiliated physician basis in the future.

Dependence upon Affiliated Medical Practices

       Although the Company does not and will not employ physicians or control
the medical aspects of the practices of the physicians employed by the
Springfield Affiliated Group, the Flagship Affiliated Group or similar
Affiliated Groups, the Company's revenue and profitability are directly
dependent on the revenue generated by the operation and performance of and
referrals among the affiliated medical practices. The compensation to the
Company under its Service Agreements with the Affiliated Groups is based upon a
percentage of the profits generated by the Affiliated Groups' practices with a
substantial portion of the profits being allocated to the physicians until
threshold levels of income, based upon the physicians' historical compensation,
are achieved. Accordingly, the performance of affiliated physicians affects the
Company's profitability and the success of the Company depends, in part, upon an
increase in net revenues from the practice of affiliated physicians compared to
historical levels. The inability of the Company's Affiliated Groups to attract
and retain patients, to manage patient care effectively and to generate
sufficient revenue or a material decrease in the revenues of the Affiliated
Groups would have a material adverse effect on the financial performance of the
Company. To the extent that the physicians affiliated with the Company are
concentrated

                                       9
<PAGE>
 
in a limited number of target markets, as is currently the case in western
Massachusetts and Maryland, deterioration in the economies of such markets could
have a material adverse effect upon the Company.

Need to Hire, Retain and Integrate Physicians

       The success of the Company is dependent upon its ability to affiliate
with a significant number of qualified physicians and the willingness of such
affiliated physicians to maintain and enhance the productivity of their
practices following affiliation with PQC. The market for affiliation with
physicians is highly competitive, and the Company expects this competition to
increase. The Company competes for physician affiliations with many other
entities, some of which have substantially greater resources, greater name
recognition and a longer operating history than the Company and some of which
offer alternative affiliation strategies which the Company may not be able to
offer. In addition, under current law the Company has no or only limited ability
to enforce restrictive covenants in the employment agreements with the
physicians with whom the Company affiliates. The Company is subject to the risk
that physicians who receive affiliation payments may discontinue such
affiliation with the Company, resulting in a significant loss to the Company and
a decrease in the patient base associated with such affiliated physicians. There
can be no assurance that PQC will be able to attract and retain a sufficient
number of qualified physicians. If the Company were unable to affiliate with and
retain a sufficient number of physicians, the Company's operating results and
financial condition would be materially adversely affected. A material increase
in costs of affiliations could also adversely affect PQC and its stockholders.

       In the Springfield and greater Baltimore-Annapolis areas and in other
potential affiliation markets, the Company is integrating physician practice
groups that have previously operated independently. The Company may encounter
difficulties in integrating the operations of such physician practice groups and
the benefits expected from such affiliations may not be realized. Any delays or
unexpected costs incurred in connection with integrating such operations could
have an adverse effect on the Company's business, operating results or financial
condition.

Management of Expanding Operations

       The Company is seeking to expand its operations rapidly, which, if
successful, will create significant demands on the Company's administrative,
operational and financial personnel and systems. There can be no assurance that
the Company's systems, procedures, controls and staffing will be adequate to
support the proposed expansion of the Company's operations. The Company's future
operating results will substantially depend on the ability of its officers and
key employees to integrate the management of the Affiliated Groups, to implement
and improve operational, financial control and reporting systems and to manage
changing business conditions.

Dependence upon Growth of Managed Healthcare Plans

       The Company believes that the future growth in the demand for its
practice management services is dependent, among other things, upon the
enrollment of managed healthcare plans and the ability of the Company to help
Affiliated Groups attract managed healthcare contracts. There can be no
assurance, however, that such growth in enrollment will occur, that growth in
the demand for practice management services will follow, or that the Company
will be able to assist the Affiliated Groups in attracting such contracts. Such
developments could have a material adverse effect on the Company's prospects.

Industry Integration and Consolidation

       The healthcare industry is in the process of rapid and fundamental
change, triggered by the deregulation of the acute care hospital reimbursement
system in many states and the growing strength of managed care plans. The growth
of the managed care industry is being driven, in part, by increasing pressure
from employers and other purchasers who are seeking to reduce their healthcare
premium costs. As the healthcare market in many states shifts from a heavily
regulated, largely fee-for-service payment system towards a deregulated,
capitated payment system, large integrated delivery systems are developing.
These

                                       10
<PAGE>
 
systems are intended to provide adequate geographical coverage for major
purchasers of healthcare and to provide a system in which significant cost
savings can be realized from efficiencies resulting from the alignment of the
financial interests of physicians and other providers. Many of these integrated
systems may be substantially larger and better capitalized than the Company. In
addition, the rapidly changing alignment of numerous market participants creates
an uncertain environment in which it may be difficult for smaller market
participants, such as the Company, to implement an effective strategic plan. The
Company's inability to implement its business strategy could have a material
adverse effect on the Company.

Regulatory Environment

       The healthcare industry is subject to extensive federal and state
regulation. Changes in the regulations or interpretations of existing
regulations could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business -- Governmental
Regulations."

       Prohibition on Corporate Practice of Medicine. The laws of most states,
including Massachusetts and Maryland, prohibit business corporations such as the
Company from practicing medicine or employing physicians to do so. The
contractual relationships with the Affiliated Groups are designed to comply with
these laws. Because there is very limited judicial or regulatory interpretation
of the scope of these laws in most states, however, there can be no assurance
that the Company's contractual arrangements will be found to comply with such
laws. Any determination that such contractual relationships violate such laws
could have a material adverse effect on the Company, and there can be no
assurance that the Company would be able to restructure its arrangements on
favorable terms or at all.

       The Massachusetts Board of Registration in Medicine (the "BRM") has
proposed regulations that, if promulgated as proposed, might limit physicians
licensed within the Commonwealth of Massachusetts in entering into management
contracts with proprietary business entities unless a majority of the governing
board of those business entities are licensed physicians and certain other
conditions are met. The BRM also indicated that it may seek to limit
significantly the extent to which proprietary business entities may have control
or consultation rights with respect to medical decisions or business decisions
that may affect patient care, such as the amount of time each physician spends
with a patient. Extensive commentary has been filed in opposition to the
proposed regulations, and it is not known whether, when or in what form final
regulations will be promulgated. The final regulations may have a material
adverse effect on the Company's relationship with the Springfield Affiliated
Group and its ability to operate in Massachusetts as currently contemplated.
Comparable regulations have not been proposed in Maryland, but there can be no
assurance that such regulations will not be proposed or adopted.

       Stark Law. The federal law commonly known as the "Stark law"
significantly limits the ability of physicians to maintain any ownership or
other financial relationship with an entity (including their own group practice)
to which they refer patients for a broad class of "designated health services",
including ancillary services such as laboratory and radiology services. The
Stark law is extremely broad and complex, and extensive regulations have been
promulgated governing the application of the Stark law to physician
relationships with clinical laboratories. These clinical laboratory regulations
are difficult to apply to many common situations, and regulations have not yet
been issued applying the law to other designated health services. However, the
government has indicated that it will look to the regulations applicable to
clinical laboratories for guidance with respect to the law's application to
other designated health services. Significant monetary penalties and denial of
reimbursement may be assessed for violation of the Stark law, and a provider may
be excluded from the Medicare and state health programs in certain instances. In
addition, violation of the Stark law may result in assertion of a federal false
claim, which could result in civil and criminal penalties. The assertion or
determination that the Company's contractual relationship with the physicians
employed by the Affiliated Groups or the relationship of the physicians within
one or more Affiliated Groups was in violation of the Stark law could have a
material adverse effect on the Company. In addition, there can be no assurance
that, in the event of such assertion, the Company would be able to restructure
its relationships with the Affiliated Groups upon favorable terms or at all.

                                       11
<PAGE>
 
       Fraud and Abuse Laws. Federal law and the laws of many states prohibit
the offer, payment, solicitation or receipt of any form of remuneration in
return for the referral of Medicare or state health program (such as Medicaid)
patients or in return for the purchase or order of items or services that are
covered by Medicare or state health programs. These laws are commonly referred
to as the "fraud and abuse" laws. Violations of the fraud and abuse laws may
result in substantial civil or criminal penalties for individuals or entities,
including large monetary penalties and exclusion from participation in the
Medicare and state health programs. The Company has attempted to structure its
contractual relationships with the Affiliated Groups so as to avoid violating
the fraud and abuse laws, but in view of the broad and ambiguous nature of such
laws and the lack of applicable safe harbor exceptions, there can be no
assurance that the Company's contractual relationships with the Affiliated
Groups comply with such laws. Any allegation or determination that the Company
or the Affiliated Groups have violated the fraud and abuse laws could have a
material adverse effect on the Company.

       Healthcare Reform. The United States Congress has considered various
types of healthcare reform, including comprehensive revisions to the current
healthcare system. It is uncertain what legislative proposals will be adopted in
the future, if any, or what actions federal or state legislatures or third party
payors may take in anticipation of or in response to any healthcare reform
proposals or legislation. Healthcare reform legislation adopted by Congress
could, among other things, result in lower payment levels for the services of
physicians managed by the Company and lower profitability for the Affiliated
Groups, which could have a material adverse effect on the operations of the
Company.

Risks of Capitated Contracts

       The physician groups with which the Company is affiliated and proposes to
affiliate with are parties to certain capitated contracts with third party
payors, such as insurance companies. The Company intends to seek to expand the
capitated patient base of its Affiliated Groups, particularly for Medicare
enrollees. In general, risk contracts pay a flat dollar amount per enrollee in
exchange for the physician's obligation to provide or arrange for the provision
of a broad range of healthcare services (including in-patient care) to the
enrollee. A significant difference between a full risk capitated contract and
traditional managed care contracts is that the physician is sometimes
responsible for both professional physician services and many other healthcare
services, e.g., hospital, laboratory, nursing home and home health. The
physician is not only the "gatekeeper" for enrollees, but is also financially at
risk for over-utilization and for the actuarial risk that certain patients may
consume significantly more healthcare resources than average for patients of
similar age and sex (such patients are referred to herein as "high risk
patients"). While physicians often purchase reinsurance to cover some of the
actuarial risk associated with high risk patients, such insurance typically does
not apply with respect to the risk of over-utilization until a relatively high
level of aggregate claims has been experienced. If over-utilization occurs with
respect to a given physician's enrollees (or the physician's panel of enrollees
includes a disproportionate share of high risk patients not covered by
reinsurance), the physician is typically penalized by failing to receive some or
all of the physician's compensation under the contract that is contingent upon
the attainment of negotiated financial targets, or the physician may be required
to reimburse the payor for excess costs. In addition, a physician may be liable
for over-utilization by other physicians in the same "risk pool" and for
utilization of ancillary, in-patient hospital and other services when the
physician has agreed contractually to manage the use of those services. Because
the Company's financial results are dependent upon the profitability of such
capitated contracts, the Company's results will reflect the financial risk
associated with such capitated contracts. See "Business -- Industry Overview."
Liabilities or insufficient revenues under capitated and other risk-sharing
arrangements could have a material adverse effect on the Company.

Exposure to Professional Liability; Liability Insurance

       In recent years, physicians, hospitals and other participants in the
healthcare industry have become subject to an increasing number of lawsuits
alleging medical malpractice, negligent credentialing of physicians, and related
legal theories. Many of these lawsuits involve large claims and substantial
defense costs. There can be no assurance that the Company will not become
involved in such litigation in the future. Through its management of practice
locations and provision of non-physician healthcare personnel, the Company could

                                       12
<PAGE>
 
be named in actions involving care rendered to patients by physicians or other
practitioners employed by Affiliated Groups. In addition, to the extent that
affiliated physicians are subject to such claims, the physicians may need to
devote time to defending such claims, adversely affecting their financial
performance for the Company, and potentially having an adverse effect upon their
reputations and client base. The Company and the Affiliated Groups maintain
professional and general liability insurance. Nevertheless, certain types of
risks and liabilities are not covered by insurance, and there can be no
assurance that the limits of coverage will be adequate to cover losses in all
instances.

Certain Federal Income Tax Considerations

       Physician groups which operated as professional corporations ("PCs") in
Springfield prior to affiliating with the Company were merged into the
Springfield Affiliated Group, with stockholders of each PC receiving shares of
Common Stock of the Company in exchange for their capital stock in the PC.
Physician groups which operated as professional associations ("PAs") in the
greater Baltimore-Annapolis area prior to affiliating with the Company were
similarly merged into the Flagship Affiliated Group, with stockholders of each
PA receiving shares of Common Stock of the Company in exchange for their capital
stock in the PA. Each such merger is intended to qualify as a "reorganization"
under Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"Code"), in which case no gain or loss would generally be recognized by the PC
or PA or the stockholders of the PC or PA. If a merger were not to so qualify,
the exchange of shares would be taxable to both the PC or PA and the
stockholders of the PC or PA, and the shares of Common Stock issued in
connection with the merger would be taxable to the Affiliated Group into which
such PC or PA was merged. The Company has not sought or obtained a ruling from
the Internal Revenue Service or an opinion of counsel with respect to the tax
treatment of the mergers of PCs or PAs into the Springfield or Flagship
Affiliated Groups. The failure of a merger or mergers to qualify as tax-free
reorganizations could have a material adverse effect on the applicable
Affiliated Group and the Company.

New Management; Dependence on Key Personnel

       The current management structure and the senior management team of the
Company have been in place for a relatively short time. The Company's future
success depends, in large part, on the continued service of its key management,
and on its ability to continue to attract, motivate and retain highly qualified
employees. As a development stage company, PQC has experienced some turnover in
staff, including two of the founding officers. The Company and one of the
departed founders are currently in a dispute with respect to the contractual
right of the Company to repurchase certain of the founder's shares and the
founder's right to severance payments. While the Company believes that it will
prevail in such dispute, if litigation were brought and adjudicated adversely to
the Company, the Company would be adversely effected. Although the Company has
entered into employment agreements with certain of its key executives that
contain covenants not to compete with the Company, there can be no assurance
that the Company will be able to retain such key executives or its senior
managers and employees. The inability to hire and retain qualified personnel or
the loss of the services of key personnel could have a material adverse effect
upon the Company's business and future business prospects.

Voting Control

       Pursuant to the Company's Restated Certificate of Incorporation (the
"Restated Certificate") and the Stockholders Agreement, affiliates of Bain
Capital (the "Institutional Investors") as the holders of Class B Common Stock
have the right to appoint the Class B Directors, two of the eleven members of
the Board of Directors of the Company and the Institutional Investors have the
right to approve seven of the other directors. The Class B Directors are
entitled to five votes each, giving them a majority of the voting power of the
Board of Directors, (i) with respect to certain actions of the Company,
including public offerings, issuances and redemptions of equity securities,
declarations of dividends, incurrences of debt, mergers, assets sales and
liquidation of the Company and its affiliates, material amendments to the
management agreements between the Company and its affiliates and employment of
the Chief Executive Officer, and (ii) with respect to any matter before the
Board of Directors upon the occurrence of certain events, including the failure
of the Company to meet certain financial objectives. In addition to being
approved by the Board of Directors, certain

                                       13
<PAGE>
 
actions of the Company, including mergers, material asset sales, liquidation,
certain medical practice affiliation transactions, dividends, material changes
in the business of the Company or its affiliates, retention and dismissal of the
Chief Operating and Financial Officers, transactions with affiliates and
commencement and management of material litigation, must be approved by the
Institutional Investors. See "Business -- Bain Financing" and "Description of
Capital Stock." As a result of those provisions of the Restated Certificate and
"drag-along" rights in the Stockholders Agreement, the Institutional Investors
and Bain Capital have significant control over the actions of the Company
including if and when the Company is sold to a third party or a public market
for the Company's Common Stock is established.

Dilution

       The Company expects to continue to issue Class A Common Stock as a
principal component of the consideration for future affiliation transactions. To
the extent that all or a portion of future affiliation transactions are paid in
cash, the Company may need to issue additional equity securities to fund such
payment or to fund anticipated operating losses. If the Company achieves its
goal of affiliating with a significant number of physicians, the number of
shares issued may be substantial. Accordingly, the percentage ownership interest
of each then existing stockholder in the Company will be reduced proportionately
and, depending upon the valuation at which such securities are issued and the
method for determining the value of practices that enter into affiliation
transactions, such issuances may be dilutive to the then existing stockholders.
Certain officers of the Company also acquired their interest in the Company at a
substantially lower cost per share than the value being place upon the Common
Stock in the Affiliations. See "Dilution."

Potential Conflicts of Interest

       Certain conflicts of interest are inherent in the structure of the
Company and its contractual and organizational relationships. The President of
the Springfield Affiliated Group (who is also a director of the Company) is a
practicing physician in the Springfield Affiliated Group, the president of the
Flagship Affiliated Group is a practicing physician in the Flagship Affiliated
Group and two directors of the Company, one of whom is also President of the
Company, are practicing physicians in the Flagship Affiliated Group. Two
directors of the Company are affiliated with Bain Capital, Inc. which, through
the Institutional Investors, is the primary financing source for the Company.
From time to time, the interests of such persons, and persons serving in
multiple roles in existing and future affiliation transactions, may conflict
with those of the Company due to such relationships. See also "-- Voting
Control" and "Certain Transactions."

Antitrust Considerations

       The Company, its affiliated physicians and other entities with which it
contracts are subject to the United States and state antitrust statutes. Because
the Company will be contracting with third party payors and other entities who
could be deemed to compete with the Company or its Affiliated Groups, and for
other reasons, the Company, its affiliated physicians and other entities with
which it contracts could be subject to public and private investigations and
enforcement actions under such statutes.

Forward-Looking Statements

       Certain statements made in this Prospectus are forward-looking, including
without limitation statements with respect to the future affiliations, capital
requirements, future plans for expansion and future success of the Company, and
future development of the healthcare industry. Forward-looking statements made
herein are not guarantees of future performance and are subject to risks and
uncertainties, including without limitation the factors discussed in this "Risk
Factors" section, that could cause actual results to differ materially from
those described in the forward-looking statements.

                                USE OF PROCEEDS

       In exchange for the Common Stock (and other consideration in certain
cases), PQC expects that its Affiliated Groups will receive certain assets of or
ownership interests in the physician practices, as well as certain contractual
rights.

                                DIVIDEND POLICY

       PQC has not declared or paid any dividends on its Common Stock and does
not anticipate paying cash dividends in the foreseeable future. The terms of the
Bain Financing restrict the payment of dividends. It is the present intention of
the Board of Directors to reinvest any earnings in the business of the Company
to support growth of its operations.

                            Selected Financial Data

                     (in thousands, except per share data)



       The following selected financial data for the Company and the Predecessor
should be read in conjunction with the financial statements and notes thereto,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the pro forma financial statements of the Company and the notes
thereto, included elsewhere in this Prospectus. The selected financial data of
the Predecessor as of December 31, 1993, 1994 and 1995 and for the period from
January 1, 1996 to August 30, 1996, have been derived from the financial
statements of the Predecessor, which have been audited by Ernst & Young LLP,
independent auditors. The selected financial data of the Company for the period
from March 20, 1995 (inception) through December 31, 1995 and for the year ended
December 31, 1996, have been derived from financial statements of the Company
which have been audited by Ernst & Young LLP, independent auditors. Ernst &
Young LLP's report on the financial statements of the Company for the year ended
December 31, 1996 and Note 2 to such financial statements which are included in
this Prospectus describe an uncertainty about the Company's ability to continue
as a going concern. The pro forma selected financial data for the Predecessor
for the year ended December 31, 1996 is unaudited. However, such financial
statements have been derived from the financial statements of the Predecessor
for the period from January 1, 1996 to August 30, 1996, which have been audited
by Ernst & Young LLP, and the unaudited financial statements of the Predecessor
for the period August 31, 1996 to December 31, 1996. These unaudited financial
statements include all adjustments consisting of normal, recurring accruals the
Company considers necessary for a fair presentation of the financial position
and the results of operations for this period.

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



     The following discussion should be read in conjunction with "Selected
Financial Data, the Company's Financial Statements and Notes thereto and the
Predecessor's Financial Statements and Notes thereto, included elsewhere in this
Prospectus.

Overview

     The Company affiliates with and operates multi-specialty medical practice
groups. The first physician affiliation took place on August 30, 1996, with 32
physicians in the Springfield, Massachusetts and Enfield, Connecticut area,
including the Predecessor. On December 11, 1996, PQC consummated the affiliation
with the Flagship Affiliated Group, which consisted of 59 physicians in
Baltimore and Annapolis, Maryland. PQC is working with these groups of
physicians to improve operating practices and to obtain managed care contracts.

     Financial information prior to March 20, 1995 represents the results of
operations of the Predecessor. Because the Springfield Affiliation was
consummated on August 30, 1996 and the Flagship Affiliation was completed on
December 11, 1996, the financial statements of PQC are not directly comparable
to those of the Predecessor. For purposes of comparison, this discussion reviews
the actual results of PQC and the pro forma results of the operations of the
Company as if the affiliation transactions had occurred at the beginning of 1996
and the aggregate results of operations for the Predecessor.

Results of Operations

The Company

Pro Forma Results of Operations for Year Ended December 31, 1996

     PQC on a proforma basis, as if the Springfield and Baltimore transactions
had been completed at the beginning of the period for the year ended December
31, 1996, had management fee revenue of approximately $22.5 million. Operating
expenses were $27.4 million, the most significant of which included $18.1
million of non-physician practice expenses and $6.3 million of general corporate
expense. The net loss for the period was $4.6 million.

  Year Ended December 31, 1996 and Period from March 20, 1995 to December 31,
1995

     Although the completion of the Springfield and Baltimore affiliation
transactions resulted in the Company having revenue of $3.8 million for the year
ended December 31, 1996 as compared to no revenue in the period from March 20,
1995 to December 31, 1995, increases in expense, particularly corporate expense,
exceeded the growth of revenues. The $3.9 million increase in general corporate
expense in fiscal 1996 as compared to the period from inception to December 31,
1995 reflects the increase in corporate and regional office level personnel
necessary to support operations, finance and affiliations. Due to the completion
of the affiliation transactions, depreciation, amortization and the provision
for bad debts are significantly higher. Amortization of goodwill acquired in the
transactions will increase in future periods as it is reflected for a full year
and as future transactions are completed. The profitability of the Company in
future periods will be dependent upon an increase in the revenues of the
affiliated physicians and the Company's ability to control general corporate and
other expenses.

The Predecessor

Year Ended December 31, 1996 (pro forma) and December 31, 1995

     The Predecessor's net patient revenue from fiscal 1996 to fiscal 1995
increased by 27.7% from $7.0 million in 1995 to $9.0 million in 1996. Revenue
growth was driven by the maturing practices of new

                                       17
<PAGE>
 
physicians joining the second Springfield, Massachusetts facility in 1994 and
1995 and increased patient visits and fees generated for sub-speciality services
through the capitated Medicare Risk contract with Tufts Health Plan's Secured
Horizons product. Physician compensation and benefits declined 13.2% from $2.3
million in 1995 to $2.0 million in 1996, but the recorded physician compensation
does not include the distribution of net income to physicians. Physician
compensation and net income combined increased by 1.2% from $2.4 million in 1995
to $2.43 million in 1996. Non-physician salaries and benefits increased by 9.5%
from $1.9 million in 1995 to $2.1 million in 1996 due to a partial year of
increased staffing necessary to support higher practice volume. Other non-salary
practice expenses increased 41.4% from $2.9 million in fiscal 1995 to $4.1
million in fiscal 1996 and as a percentage of revenue increased from 41.8% to
46.3%. The most significant reason for the increase of non-salary practice
expenses was an increased reserve for bad debt expense in the first eight months
of 1996. For the last four months of 1996, the Predecessor paid a management fee
of $71,310 to PQC reflecting the new compensation arrangement as part of the
affiliation. Income taxes were deducted in 1996 at a 40% rate due to the
profitability of the business as compared to a tax benefit in 1995. Net income
in 1996 was $420,548 in 1996 as compared to $86,160 in 1995, an increase of
388%.

Year Ended December 31, 1995 and December 31, 1994

     Net patient service revenue increased by 5.4% to $7.02 million for the year
ended December 31, 1995 from $6.66 million for the year ended December 31, 1994.
The increase was driven by continued patient volume growth from the established
physicians plus the full year revenues from a second primary care physician
("PCP") satellite facility and an additional specialist physician. The earnings
retained by physicians declined by 6.3% from $2.47 million in fiscal 1994 to
$2.32 million in fiscal 1995 due primarily to the fact that partner physicians
were subsidizing the start-up of the new PCP facility. Non-physician salaries
and benefits grew 6.4% from $1.81 million in fiscal 1994 to $1.93 million in
fiscal 1995, reflecting a growth of facilities and number of physicians. Other
practice expenses grew 19.1% over this same period from $1.61 million to $1.92
million due to a full year impact of the opening of the PCP satellite facility.
Depreciation and amortization increased 32.0% from $97,000 in the year ended
December 31, 1994 to $128,000 in the year ended December 31, 1995 due to the
increase in fixed assets associated with the satellite PCP facility. Provision
for bad debts increased by 17.2% from $0.76 million to $0.89 to match an
increase in accounts receivable and to reflect different collection assumptions
in the payor base. The net income over this period increased from a loss of
$62,000 to a profit of $86,000 due to lower revenue retained by physicians.

Year Ended December 31, 1994 and December 31, 1993

     Net patient service revenue increased by 7.7% to $6.66 million in the year
ended December 31, 1994 from $6.19 million for the year ended December 31, 1993.
The increase was driven by continued growth of patient volume through the group
and its PCP satellite facility in Enfield, Connecticut. The earnings retained by
physicians increased by 3.7% from $2.38 million to $2.47 million due to
increased revenues. Non-physician salaries and benefits grew 12.3% over this
period from $1.62 million to $1.81 million, reflecting the increase in support
cost when two new physicians joined the group in August 1994. The physicians
included one specialist and one PCP who staffed a second PCP satellite facility
at a second site in Springfield, Massachusetts. Other practice expenses grew
17.4% over this period from $1.37 million to $1.61 million due primarily to the
set-up of the second PCP satellite facility. Depreciation and amortization
effectively was flat over this period--$97.000 in 1994 and $98,000 in 1993. The
provision for bad debts increased by 12.9% from $0.67 million to $0.76 million
to match an increase in accounts receivable and to reflect different collection
assumptions given changes in the payor base. The net income over this period
decreased from a profit of $35,000 to a loss of $62,000 due to increased costs
related to the satellite facility opening.

Liquidity and Capital Resources

     The Company's principal requirements for capital are payments to physicians
in connection with affiliation transactions with the Company and its Affiliated
Groups, transaction costs associated with such affiliation transactions, working
capital requirements for its Affiliated Groups and the funding of operating
losses. Due to its start-up status, the Company has incurred significant
operating losses to date and does not have operating cash flow to fund growth or
further losses. The Company cannot continue as a going concern

                                       18
<PAGE>
 
without external capital sources. The Company's principal sources of capital to
date have been the issuance of Class B Common Stock under the Bain Financing,
issuances of Class A Common Stock to Physician Stockholders, other issuances of
Class A Common Stock to private investors and borrowing under a Credit Agreement
with Bankers Trust Company.

     During 1996, the Company paid aggregate consideration of approximately
$29.5 million in connection with affiliation transactions. Of such amount,
approximately $5.9 million was paid in cash and approximately $23.6 million was
paid in Class A Common Stock. The majority of such payments were accounted for
as an addition to goodwill, which represented $28 million of the Company's total
assets of $39 million at December 31, 1996. The Company is amortizing the
goodwill over 40 years.

     The Company has generally purchased the working capital of practices in
affiliation transactions. Therefore, additional working capital investment is
generally only required to the extent billing processing is slowed during payor
administrative changes after an affiliation and also to fund growth of revenues.
At December 31, 1996, the Company and its affiliated entities had total net
accounts receivable of $5.4 million and the Predecessor had aggregate accounts
receivable of approximately $900,000 at each of December 31, 1995 and 1994.

     The Company has executed a contract with HBO and Company that obligates the
Company to purchase $1.1 million worth of equipment and licenses pertaining to
practice management systems. The term of the contract is five years.

     At March 31, 1997, Bain Capital had $20 million of unused commitment to
purchase the Company's Class B Common Stock. The Institutional Investors'
obligations to fund such commitments are subject to numerous conditions and
there can be no assurance that such equity capital will be available when
needed. Pursuant to the Bain Financing, the Company has also agreed that it will
not use other sources of equity or debt financing, other than bank financing,
without the consent of the Bain Capital. See "Business -- The Bain Financing."

     On January 16, 1997, the Company entered into the Credit Agreement with
Bankers Trust, as Agent, and the lenders from time to time a party thereto,
pursuant to which the lenders have agreed, subject to the terms and conditions
set forth in the Credit Agreement, to provide a revolving credit facility (the
"Facility") to the Company in an aggregate amount of up to $3.5 million (subject
to downward adjustment in the event that the Company and the Affiliated Groups
do not maintain an adequate amount of accounts receivable). On March 31, 1997,
the Company's outstanding borrowings under the Facility were $3.0 million and
the remaining available commitment on such date was $500,000. The Company will
need to repay or refinance the outstanding balance under the Credit Agreement
when the facility terminates in January 1998. While the Company currently
expects to enter into a replacement credit facility there can be no assurance
that the Company will be able to do so or to do so on terms favorable to the
Company. See "Business -- The Credit Agreement."

     In addition to the Bain Financing, borrowing under the Credit Agreement and
cash generated by the operations of the Affiliated Groups, the Company has also
obtained capital to fund operating losses and affiliation payments through the
private placement of Common Stock. In August 1996, the Company issued $1.0
million of convertible notes, all of which were converted into Common Stock at a
conversion price of $2.50 per share on August 30, 1996. On December 31, 1996 and
February 12, 1997, the Company issued an aggregate of 614,000 additional shares
of Common Stock at $2.50 per share for a total consideration of $1.535 million.

                                    BUSINESS

The Company

     Physicians Quality Care, Inc., which was incorporated in March 1995,
provides practice management services for multi-specialty medical practice
groups. The Company's objective is to establish networks of primary and
specialty care physicians and related diagnostic and therapeutic support
services which can provide comprehensive healthcare services in targeted
geographic areas.

     PQC's strategy has four central elements: developing economies of scale and
geographic penetration by affiliating with large numbers of qualified physicians
in targeted geographic areas, assisting the affiliated practices in providing
cost-effective healthcare to special populations, building comprehensive local
healthcare networks by developing contractual or strategic relationships with
providers of, or eventually itself providing, ancillary services such as home
healthcare and weight and health management and improving practice performance
by seeking to maximize the value of each physician encounter. To date, the
Company has focused upon developing its presence in western Massachusetts,
northern Connecticut and Maryland. The Company believes that once the Company
has developed a large base of affiliated physicians its strategy will enable the
Company to generate increased demand for the services and capabilities of its
affiliated physicians, treat patients in lower cost settings and negotiate
favorable managed care contracts. The Company intends to achieve growth through
the recruitment of additional physicians, the expansion of managed care
relationships and the development of contractual or strategic relationships with
providers of ancillary services.

     The core of PQC's proposed integrated healthcare delivery system is its
affiliation with groups of physicians who enter into long-term management
agreements with the Company. The Company assumes responsibility for non-medical
aspects of an affiliated physician's practice and focuses its efforts on seeking
to increase revenues and improve operating margins, implementing management
information systems and negotiating managed care contracts. The physicians
remain responsible for, among other things, the medical, professional and
ethical aspects of their practices. By affiliating with the Company, physicians
have increased opportunity to access capital, continue to participate in the
profitability of their individual practices and, through stock ownership, share
a financial interest in the overall performance of the Company.

Industry Overview

     Traditionally, health insurance plans reimbursed providers on a fee-for-
service basis, a system that offered very little incentive for efficiency. In
recent years, the healthcare industry has undergone significant changes as both
the private and public sectors seek to slow spending growth. Since the early
1980s, much of the healthcare coverage in the U.S. has shifted to managed care
systems which offer cost savings in exchange for limiting the utilization of
services. Moreover, there has been a shift to prepaid insurance plans that offer
comprehensive healthcare services to enrollees and pay providers a fixed,
prepaid monthly premium. The most prevalent of these prepaid health insurance
alternatives is the health maintenance organization ("HMO"). To remain
competitive, HMOs and other similar payors seek to align themselves with the
most cost- and service-effective providers, generally channeling patient volume
to such providers.

     In the managed care environment, doctors must contract or affiliate with
leading insurers or healthcare networks in their practice area. The third-party
payors rely on primary care physicians to play a "gatekeeping" role and to make
important medical decisions for the patient. Many payors look to share the risk
of providing services through capitation arrangements which provide for fixed
payments for patient care over a specified period of time. In general, capitated
contracts pay a flat dollar amount per enrollee in exchange for the physician's
obligation to provide or arrange for the provision of a broad range of
healthcare services (including inpatient care) to the enrollee. A significant
difference between a capitated contract and traditional managed care contracts
is that the physician is sometimes responsible for both professional physician
services and many other healthcare services, e.g., hospital, laboratory, nursing
home and home health. The physician is not only the "gatekeeper" for enrollees,
but is also financially at risk for over-utilization and for the actuarial risk
that certain patients may consume significantly more healthcare resources than
average for patients of similar age and sex (such patients being referred to as
"high risk

                                       20
<PAGE>
 
patients"). Although physicians often purchase reinsurance to cover some of the
actuarial risk associated with high risk patients, such insurance typically does
not apply with respect to the risk of over-utilization until a relatively high
level of aggregate claims has been experienced. If over-utilization occurs with
respect to a given physician's enrollees (or if the physician's panel of
enrollees includes a disproportionate share of high risk patients not covered by
reinsurance), the physician typically is penalized by failing to receive some or
all of the physician's compensation under the contract that is contingent upon
the attainment of negotiated financial targets, or the physician may be required
to reimburse the payor for excess costs. In addition, a physician may be liable
for over-utilization by other physicians in the same "risk pool" and for
utilization of ancillary, inpatient hospital and other services when the
physician has agreed contractually to manage the use of those services. Under
this payment system, primary care physicians have important economic incentives
to reduce costs by ensuring the efficient utilization of other providers of
care, shifting care to outpatient settings where feasible, monitoring the
progress of patients throughout the course of treatment and encouraging
preventive healthcare.

     In this environment, physicians are facing reimbursement pressures, greater
administrative burdens, increasing financial responsibility for the risk of
patient care, and a shift in demand from specialty to primary care. In addition,
legislative changes have substantially limited a physician's ability to maintain
an ownership interest in entities that provide ancillary services such as
outpatient laboratories, infusion centers and diagnostic and rehabilitation
facilities. These factors have all contributed to a moderation, if not
reduction, in the growth of many physicians' incomes. With greater oversight by
third-party payors, physicians are also facing a decrease in control over
medical decisions and the administration of their practices.

     In response to these changes in the marketplace, many physicians are
joining together to maintain clinical autonomy, create greater negotiating
leverage vis-a-vis HMOs and other third party payors and reduce escalating
administrative costs. Physicians also are increasingly abandoning traditional
private practice which typically has higher operating costs and little
purchasing power with suppliers and must spread overhead over a relatively small
revenue base in favor of affiliations with larger organizations. Three basic
groups have emerged as managers of physician practices each of which encompasses
several variations in format: hospitals, which may employ physicians directly or
provide support through a management services organization ("MSO"); insurance
companies, which may employ physicians directly through HMOs or may provide
management services through an affiliated MSO; and independent, investor-owned
physician practice management companies.

Company Strategy

     The Company believes that physician practice management companies ("PPMs"),
such as PQC, offer physicians significant advantages over other alternatives in
the industry consolidation. PPMs provide physicians with improved practice
management and an opportunity to participate in the growth of the PPM through
stock ownership while maintaining control over medical decisions. The physician
market is currently highly fragmented, and PPMs and other organizations
providing physicians with management alternatives have thus far captured only a
small portion of this potential market. Thus, the Company believes there is a
significant opportunity to expand the number of its affiliated physicians.

     In addition, the Company believes that because physicians can serve as
gatekeepers for patient care, they can exercise direct control over healthcare
spending and should be in a position to share in the savings generated by the
cost containment practices they adopt. For a fee or a percentage of the group's
earnings, a PPM provides physician groups with administrative and practice
management services that are needed for a physician group to realize these cost
savings and to seek to optimize contractual relationships with managed care
organizations, thus retaining some or most of the cost savings so generated.

     The central elements of the Company's strategy are to develop long-term
affiliations with physicians, focus on cost effective healthcare delivery to
special populations, and build comprehensive local healthcare networks. To date,
the Company has focused upon developing a network of affiliated physicians. The
Company believes that its strategy will enable the Company to generate increased
demand for the services

                                       21
<PAGE>
 
and capabilities of its affiliated physicians, treat patients in lower cost
settings and negotiate favorable managed care contracts.

     Develop long-term affiliations with physicians. PQC seeks to affiliate with
physicians in solo or group practices by entering into contractual arrangements
pursuant to which PQC, or a professional corporation or professional association
affiliated with PQC, assumes management of non-medical aspects of the practices.
Upon affiliation, PQC seeks to provide the physicians with, among other things,
increased opportunity to access capital, management experience, improved
information systems and increased opportunity to participate in favorable
managed care contracts. The Company intends to assist affiliated physicians in
improving clinical outcomes and seeks to keep medical costs down by merging
physicians into Affiliated Groups. The Company's structure allows physicians to
continue to practice in their existing locations with no disruption to patient
flow patterns while providing access to coordinated ancillary services. By
affiliating with PQC, physicians, through the revenue sharing provisions of
their employment agreements and the Services Agreements between the Affiliated
Group and PQC, continue to participate in the profitability of their individual
practices and, through stock ownership, share a financial interest in the
overall performance of the Company. Physicians constitute a majority of the
Board of the Directors of PQC and all local advisory boards, which control such
decisions as clinical protocols and utilization review, payor relations and the
addition of ancillary services.

     Balance of Primary Care Physicians and Specialists. PQC believes that a
successful system should be balanced between primary care physicians and
specialists to provide efficient coordination and utilization of the appropriate
levels of care, and PQC intends to seek to develop this balance in the physician
groups with which it affiliates. Of the 98 physicians currently affiliated with
the Company at March 31, 1997, 65 are engaged in primary care practices and 33
are engaged in specialist practices. The Company believes the industry trend
toward integrated delivery systems will result in an increasing demand for
primary care physicians because a higher degree of coordination of care and 
risk-sharing will be required than that which can be achieved in a system
controlled by specialists. The Company's strategy is to have the primary care
physician serve as the central manager in the patient system and to develop
effective coordination between specialists and the primary care physicians
within its network.

     Focus on special populations. PQC believes that the management of
healthcare costs for certain populations provides significant opportunities that
are not being addressed in the marketplace. Special populations, including the
elderly, the disabled and those with debilitating chronic or high-cost, complex
diseases represent a minority of the population but account for a
disproportionately high percentage of the healthcare costs in the United States.
The Company believes that a significant portion of these costs can be avoided
with effective case management, use of information systems, and coordinated use
of the full continuum of healthcare. At present, a relatively small percentage
of these patients are enrolled under capitated contracts. However, the Company
believes that the cost pressures that fostered the development of managed care
for other segments of the population should have an even more significant impact
on the rapid development of managed care for such patients. Through affiliation
with physicians and academic experts who specialize in geriatrics and medical
conditions that disproportionately affect these population segments, effective
use of case management techniques designed specifically for such populations,
and management information systems, the Company believes that its affiliated
physicians should be able to manage cost effectively the risks of providing care
to these populations on a capitated basis.

     Improved Medical Quality and Performance. Over time, the Company intends
that its affiliated physicians will devise medical protocols and the Company
will perform outcome analyses, such that the most effective medical practices in
each network can be shared across physician groups. The Company is in the
process of establishing a quality assurance program that will incorporate peer
review, self-critiquing mechanisms, patient satisfaction surveys, continuing
medical staff development and regular continuing medical education seminars.
Once a large base of affiliated physicians at Affiliated Groups is established,
medical directors of each local care network will participate in the Company's
National Medical Advisory Board that will meet regularly to establish and review
medical standards, policies and procedures for all physicians affiliated with
the Company.

                                       22

Affiliation Structure

     General Affiliation Model. Although the details of each affiliation
transaction may differ, the Company has developed the General Affiliation Model,
designed to capture the benefits of integration while preserving significant
physician autonomy. In the General Affiliation Model, physicians initially
affiliating with the Company in each geographic area who will become
stockholders of the Company transfer their practices by mergers or asset sales
to an Affiliated Group, a newly-formed professional corporation or professional
association permitted to practice medicine under applicable law. These
physicians, along with other physicians in that geographic area who subsequently
become part of an Affiliated Group and become stockholders of the Company, the
Stockholder Physicians, execute an Employment Agreement with the Affiliated
Group at the time that they transfer their practice assets. The Affiliated
Group, in turn, enters into a 40-year Services Agreement with the Company
pursuant to which the Company agrees to provide the physicians in the Affiliated
Group with comprehensive management services in exchange for a fee. As
consideration for transferring their practices to and becoming employed by the
Affiliated Group, Stockholder Physicians receive shares of the Company's Common
Stock and in some cases cash, the amount of which is negotiated on an individual
basis between each Stockholder Physician and the Company. Physicians who are not
stockholders of the Company may also be employed by the Affiliated Group.

     All of the outstanding capital stock of each Affiliated Group is held by a
Stockholder Physician designated by the Company (the "Affiliated Group
Stockholder"). At the time of the affiliation, the Affiliated Group Stockholder
enters into an agreement with the Company and the Affiliated Group pursuant to
which he or she agrees to consult with the Company in voting the stock and
agrees to transfer the stock without consideration to another licensed physician
at the direction of the Company (the "Designation Agreement"). The Designation
Agreement provides, however, that the Affiliated Group Stockholder is not
required to consult with the Company as to matters requiring the exercise of
professional medical judgment.

     The Employment Agreements contain certain restrictive covenants, including
covenants relating to noncompetition, confidentiality and nonsolicitation of
employees. Under current law, the Company may not be able to enforce the
covenants not to compete. Each Employment Agreement generally is terminable by
the Affiliated Group with respect to any individual Stockholder Physician upon
the death or disability of such Stockholder Physician or upon the occurrence of
certain events that either interfere with the ability of such Stockholder
Physician to practice medicine or significantly diminish the value of such
Stockholder Physician's affiliation to the Affiliated Group. Each Stockholder
Physician may terminate his or her Employment Agreement under certain
circumstances, including without cause upon six months notice to the Affiliated
Group. With respect to the Flagship Stockholder Physicians (as defined below),
such notice may only be given after the first anniversary of the Employment
Agreement. The Employment Agreements also contain terms permitting or requiring
a Stockholder Physician upon certain termination events to repurchase from the
Affiliated Group the restrictive covenants and his or her practice assets upon
termination of employment. The terms of such repurchase provision may not permit
the Company to fully recover its affiliation payments to the physician or
reflect the cost of affiliation transactions at the time of termination.

     Pursuant to the Services Agreement, the Company provides (or arranges for
the provision of) a comprehensive package of services to the Affiliated Group
and its physicians, including offices and facilities, equipment, nursing and
other non-physician professional support, administrative personnel, information
systems, comprehensive professional liability insurance and general management
and financial advisory services. The Company, on behalf of the physicians in the
Affiliated Group, supervises the billing of all patients, insurance companies
and third-party payors and negotiates all contracts and relationships with
payors. The physicians remain responsible for, among other things, the medical,
professional and ethical aspects of their practices.

     Generally, under a Services Agreement, profits from patient care are first
applied to the payment of the operating expenses of the practices. Any remaining
profits are allocated between a pool from which physician compensation is paid
("Compensation Pool") and the Company. The majority of the profits are initially
allocated to the Compensation Pool until the physicians receive as compensation
a minimum level of income based upon a significant percentage of their
historical compensation. The Company receives a

                                       23
<PAGE>
 
portion of the profits as the revenues exceed such base levels. Profits from
integrated health services that may be established by the Company or an
Affiliated Group are allocated separately and will be determined based upon the
nature of the integrated health service, or in the absence of such an agreement,
50% of the profit from such services will be allocated to the Company. Because
compensation of Stockholder Physicians is a function of many factors including
the financial performance of such physicians, neither the Company nor an
Affiliated Group can guarantee that a Stockholder Physician will receive any
minimum level of compensation, and the Stockholder Physicians are not entitled
to any compensation other than their allocated share of the Compensation Pool.

     The Company believes that its General Affiliation Model offers a number of
advantages. For example, physicians remain in their pre-affiliation locations,
offering their patients the continuity and convenience of decentralized offices.
At the same time, laboratory and administrative services generally are provided
on a centralized basis, allowing the Affiliated Groups to achieve economies of
scale in purchasing and other administrative efficiencies. Moreover, the Company
believes that as it completes its initial affiliation transactions in particular
geographic markets, Affiliated Groups will provide it with both a visible
business presence and a corporate framework for securing additional affiliations
with physicians in those markets.

     The Company also believes that the decision making structure that it
establishes in connection with each Affiliated Group facilitates information
sharing and cooperation between the affiliated physicians and the Company. Each
Affiliated Group maintains its own policy making structure, including a Joint
Policy Board and a Medical Advisory Board. The Joint Policy Board is charged
with, among other things, developing certain management and administrative
policies for the Affiliated Group, approving operating and capital expenditure
budgets, approving the establishment of managed care contracts and determining
of the number and type of physicians required for the operation of the
Affiliated Group. Certain decisions that may have a material impact upon the
business, results of operation or financial condition of the Affiliated Group
must also be approved by the Affiliated Group Stockholder. The current Joint
Policy Boards have nine members: the President of the Affiliated Group (selected
by the Affiliated Group Stockholder from physicians nominated by the Stockholder
Physicians), four persons designated by the Company and four persons designated
by the Stockholder Physicians. The Medical Advisory Board, which is responsible
for providing medical input on managed care contracting by the Affiliated Group
and leading the development and dissemination of medical protocols among the
physicians, is chaired by the Medical Director of the Affiliated Group (selected
by the Affiliated Group Stockholder from physicians nominated by the Stockholder
Physicians) and consists of six other physicians elected by the Stockholder
Physicians.

     Although the Springfield and Flagship Affiliations generally track the
General Affiliation Model, the Company may depart to some extent or
significantly from it or pursue an altogether different approach in completing
future physician affiliations.

The Springfield Affiliated Group

     The Company has entered into affiliation transactions with nine medical
practices located in western Massachusetts, consisting of a total of 39
physicians, 34 of whom are stockholders in the Company (the "Springfield
Stockholder Physicians") and 5 of whom are employed by the Springfield
Affiliated Group as employees (the "Springfield Affiliation"). These physicians
treat patients from 28 towns in western Massachusetts and northern Connecticut,
which area had a total population in 1990 of approximately 650,000. Twenty-four
of the physicians are engaged in primary care practices, including two
physicians with pediatric practices. Fifteen of the physicians are engaged in
specialist practices, including pulmonology, cardiology, oncology/hematology,
infectious disease, rheumatology and gastroenterology. The Springfield
Affiliated Group leases offices in 11 locations, of which 9 are located in
Springfield, Massachusetts. Certain of the offices are leased from Springfield
Stockholder Physicians. The Springfield Affiliated Group had total patient
revenue of approximately $16.5 million for the year ended December 31, 1996. At
December 31, 1996, the Springfield Affiliates Group had a patient base of
approximately 50,000.

     The Springfield Affiliated Group has a capitated Medicare Risk contract
with Tufts Health Plan's Secure Horizons product. As of March 31, 1997, there
were 1,975 covered lives. Profitability of the Secure

                                       24
<PAGE>
 
Horizons contract is dependent upon many factors including regular utilization
review of inpatient, skilled nursing facility, home care and outpatient
services, subcapitations, close collaboration with the partner hospital, primary
care and specialist physician communication, data analysis and review and
physician leadership.

     The Springfield Affiliated Group also participates in managed care plans of
Aetna, Blue Cross and Blue Shield of Massachusetts, Cigna, Fallon Health Plan,
Health New England, Pioneer (PPO), and Tufts Health Plan.

     Consistent with the General Affiliation Model, the Springfield Stockholder
Physicians, or the professional corporations and other entities with whom they
were affiliated, merged or sold their practice assets to the Springfield
Affiliated Group in exchange for an aggregate of approximately 3,164,738 shares
of Common Stock of the Company and approximately $4.1 million in cash. The 29
initial Stockholder Physicians entered into a three-year employment agreement
with the Springfield Affiliated Group, pursuant to which each physician received
options to purchase 2,500 shares of Common Stock of PQC at an exercise price of
$2.50 per share. The options expire on the earlier of termination of employment
or three years from commencement of employment. The Physicians who subsequently
affiliated with the Springfield Affiliated Group entered into ten-year
employment agreements with the Springfield Affiliated Group. Four of these
Springfield Physician Stockholders each received options to purchase 37,500
shares of Class A Common Stock at an exercise price of $1.00 per share which
options are subject to certain vesting conditions. In addition, up to $2.15
million, payable in Class A Common Stock at $2.50 per share, may be paid in the
future to certain Springfield Stockholder Physicians provided that certain
revenue goals are met. The Springfield Affiliated Group in turn entered into a
40-year services agreement with the Company pursuant to which the Company (on
behalf of the Springfield Affiliated Group) agreed to provide management
services to the Springfield Affiliated Group physicians.

     Under the Employment Agreements with the twenty-nine initial Springfield
Stockholder Physicians, revenues from patient care remaining after payment of
operating expenses, including expenses of the Springfield Affiliated Group
("Gross Margin") are allocated first between the Springfield Affiliated Group's
Compensation Pool (the "Springfield Compensation Pool") and the Springfield
Affiliated Group in a 95%/5% proportion until 95% of the base compensation of
the Springfield Stockholder Physicians is achieved, then to payment of certain
non-operating expenses, and then 80% to the Springfield Affiliated Group and 20%
to the Springfield Compensation Pool until the Springfield Affiliated Group has
been allocated $1.5 million, with any remaining Gross Margin being divided
evenly between the Springfield Affiliated Group and the Springfield Compensation
Pool. Under the Employment Agreements with the Springfield Stockholder
Physicians who subsequently affiliated with the Springfield Affiliate Group any
Gross Margin attributable to these physicians are allocated between the
Springfield Compensation Pool and the Springfield Affiliated Group in a 80%/20%
proportion until the physicians receive 80% of their base compensation, and then
to payment of certain non-operating expenses attributable to the Springfield
Affiliated Group, with any remaining Gross Margin being divided evenly between
the Springfield Compensation Pool and the Springfield Affiliated Group. The base
compensation of the Springfield Stockholder Physicians is $6.7 million. The
allocation of Gross Margin to the Springfield Compensation Pool is calculated
separately for each fiscal period. If the Gross Margin for any such period is
negative, such negative amount constitutes an operating expense in the next
fiscal period. Pursuant to the Springfield Services Agreement, all amounts
allocated to the Springfield Affiliated Group in any fiscal period are remitted
to the Company.

     Six months prior to the third anniversary of the closing of the initial
Springfield Affiliation, the Springfield Affiliated Group (on behalf of the
Company) or a majority of the Springfield Shareholder Physicians may amend the
financial arrangements, effective as of the third anniversary of such closing,
such that the economic terms of the Springfield Stockholder Physicians'
employment agreements, taken as a whole (and giving effect to any payments or
other compensation received by the Springfield Stockholder Physicians in
connection with their affiliation), are adjusted to reflect the terms being
entered into by independent third parties for similar affiliation and employment
relationships at that time.

                                       25

     The Flagship Affiliation. On December 11, 1996, pursuant to affiliation
transactions with the Company, 15 existing professional practices located in the
greater Baltimore-Annapolis, Maryland area, consisting of a total of 59
physicians, transferred their practice assets to and became employed by the
Flagship Affiliated Group. In exchange for such affiliation, the physicians
received a combination of approximately $2.3 million in cash and 6,842,675
shares of Class A Common Stock (the "Flagship Affiliation") affiliated with
Flagship. Forty-one of the physicians are engaged in primary care practices,
including 20 physicians with pediatric practices. Eighteen of the physicians are
engaged in specialist practices, including pulmonology, cardiology,
oncology/hematology, infectious disease, rheumatology, gastroenterology and
neurology. Fifty-five physicians are stockholders in the Company (the "Flagship
Stockholder Physicians") and 4 physicians are employed by the Flagship
Affiliated Group as employees. The Flagship Affiliated Group leases 15 practice
locations in Maryland, some of which are leased from the Flagship Stockholder
Physicians. The practices included in the Flagship Affiliated Group had total
patient revenue of approximately $25 million for the year ended December 31,
1996. During the year ended December 31, 1996, the Flagship Affiliated Group had
a patient base of approximately 100,000. The majority of patient revenues are
fee-for-service rather than capitated.

     In order to effectuate the Flagship Affiliation, the Flagship Stockholder
Physicians, or the professional associations, business corporations and limited
liability partnerships with whom they were affiliated, transferred their
practice assets to the Flagship Affiliated Group by merger or by sale of assets.
The Company entered into a 40-year management services agreement with the
Flagship Affiliated Group (the "Flagship Services Agreement"), which entered
into a five-year Employment Agreement with each Flagship Stockholder Physician.
In addition, the Company entered into an agreement with the Flagship Affiliated
Group pursuant to which the Company agreed to grant options to purchase, subject
to certain conditions, up to 400,000 shares of Common Stock to the Flagship
Stockholder Physicians.

     Pursuant to the Flagship Services Agreement and the Employment Agreements
with the Flagship Stockholder Physicians, revenues from patient services
remaining after payment of third-party operating expenses ("Net Margin") will be
allocated between the Flagship Stockholder Physicians' Compensation Pool (the
"Flagship Compensation Pool") and reimbursement of the Company's direct expenses
relating to the Flagship Affiliated Group, based on a ratio of such budgeted
compensation to such budgeted expenses. Once both the Company's direct expenses
and the aggregate base physician compensation have been fully satisfied, any
remaining Net Margin will be divided evenly between the Company and the Flagship
Compensation Pool. The base compensation of the Flagship physicians is $8.15
million.

     Future Affiliation Transactions. The Company's current primary focus is on
expanding the Springfield Affiliated Group and the Flagship Affiliated Group,
and developing additional Affiliated Groups in the eastern United States. The
Company will determine which geographic markets to enter in the future based
upon consideration of the following factors (among others): (i) population and
economic profile, (ii) level of managed care penetration and effectiveness of
providers in coping with the managed care environment, (iii) physician practice
density, specialty composition, and average group size, (iv) receptivity of the
medical community to the Company's management philosophy, (v) local competition
in the physician practice management business and (vi) commercial and Medicare
reimbursement rates. The Company also regularly considers the addition of
physicians on an employee, rather than a Stockholder Physician, basis.

Ancillary Services

     In general, the Company anticipates that it will obtain access to ancillary
services, such as laboratories, skilled nursing facility services, and home
healthcare, for its Affiliated Groups through contractual relationships or
strategic alliances with other healthcare providers. The Company anticipates
that these services will be closely coordinated with services provided by its
physicians. Over time, the Company, to the extent permitted by federal and state
regulations, may seek to own some of these ancillary services, if cost and
effectiveness considerations indicate that it would be beneficial to do so and
if favorable strategic alliances cannot be entered into. As of the date of this
prospectus, the Company and its affiliated entities do not own any ancillary
services other than the Springfield and Flagship laboratories and do not have
any contractual relationships with respect to any other ancillary services. See
"-- Company Strategy."

                                       26
<PAGE>
 
Relationship With Other Provider Organizations

     The Company may, in the future, contract with other provider organizations
such as independent provider associations ("IPA") and physician hospital
organizations ("PHOs") on a selective basis. Such contracts may provide
management services, including claims processing, member services and
administrative support, for a management fee. In other areas, PQC's role may
include providing policy guidelines, medical management, credentialing and
provider contracting.

The Bain Financing

     In order to finance the cash payments made to the Springfield and Flagship
Stockholder Physicians, to fund the Company's operating expenses and to finance
subsequent affiliation and working capital requirements, PQC entered into a
financing transaction with the Institutional Investors, consisting of Bain
Capital Fund V, L.P., Bain Capital Fund V-B, L.P., BCIP Associates and BCIP
Trust Associates, L.P., on August 30, 1996. Pursuant to the Class B Stock and
Warrant Purchase Agreement entered into as of that date (the "Bain Purchase
Agreement"), the Institutional Investors are obligated to purchase and the
Company is required to sell, in each case subject to certain conditions, up to
12,000,000 shares of the Company's Class B Common Stock at a price of $2.50 per
share, together with warrants to purchase 13,000,000 shares of Class B Common
Stock (the "Class B Warrants"), of which 4,000,000 shares of Class B Common
Stock and Class B Warrants to purchase 5,549,500 shares of Class B Common Stock
have been purchased as of March 31, 1997. An additional 600,000 shares of Class
B Common Stock and 865,500 Class B Warrants were acquired on April 18, 1997 for
aggregate consideration of $1.5 million. The Class B Warrants entitle the holder
to purchase the shares of Class B Common Stock at $2.50 per share (the "Exercise
Price"). The Exercise Price is subject to adjustment (i) to reflect any stock
dividends, stock splits, reverse stock splits, reorganizations and
recapitalizations of the Company's capital stock and (ii) to prevent dilution,
on a weighted-average basis, in the event that the Company issues additional
securities at a purchase price less than the applicable Exercise Price (with the
exception of securities issued or reserved for issuance to employees pursuant to
stock option plans approved by the Company's Board of Directors).

     Pursuant to the Bain Purchase Agreement, the Company may draw down the
remaining available commitment of $20 million in two additional tranches, each
at any time prior to December 31, 1999, provided that certain conditions are
met, including without limitation the Company having met certain financial
targets, certain representations and warranties of the Company remaining true
and correct, and the Company having performed and complied in all material
respects with the terms of the Bain Purchase Agreement.

     The Institutional Investors' commitment to purchase additional Class B
Common Stock is subject to a number of conditions including the attainment of
earning before interest, taxes, depreciation and amortization ("EBITDA") and net
sales (consolidated revenues net of reserves for bad debts) targets. The
Institutional Investors are not required to (but may) purchase additional Class
B Common Stock unless EBITDA and net sales for each of the three month periods
ending on the dates specified below are equal to the minimum set forth below:

     For the three month period ended December 31, 1996, EBITDA was $(1,478,431)
and net sales were $4,932,653. There can be no assurances that the Company will
be able to achieve such EBITDA and net sales levels in the future. The Company's
ability to achieve such level of EBITDA and net sales is dependent upon the
Company increasing the number of physicians who are employed by an affiliate
with its Affiliated Groups.

     The Company has also agreed that it will not take certain actions unless
the Company receives the prior approval of the Institutional Investors. Such
actions involving the Company, its subsidiaries or any Affiliated Groups include
mergers, sales of assets, affiliation transactions, declarations of dividends or
other distributions, material changes in business, amendments to the Restated
Certificate or By-laws, the hiring, firing and compensation of the Company's
chief executive and chief financial officers, adoption of annual operating
budget, transactions with affiliates and the commencement or settlement of any
litigation.

     The Company's Class A Common Stock and Class B Common Stock are identical
except for certain special voting rights of the directors appointed by the
holders of each class. See "Description of Capital Stock."

     In connection with the Bain Financing, the Company entered into a
Management Agreement dated as of August 30, 1996 with Bain Capital Partners, V,
L.P. ("BCP V"). See "Certain Transactions."

The Credit Agreement

     On January 16, 1997, the Company entered into the Credit Agreement with
Bankers Trust, as Agent, and the lenders from time to time a party thereto,
pursuant to which the lenders agreed, subject to the terms and conditions set
forth in the Credit Agreement, to provide an aggregate amount of up to $3.5
million to the Company under the Facility. On March 31, 1997, the Company's
outstanding borrowings under the Facility were $3.0 million and the remaining
available commitment at such date was $500,000.

     Loans under the Facility (the "Loans") bear interest at (i) the higher of
(A) 0.5% over the "Adjusted Certificate of Deposit Rate" or (B) the prime rate
announced by Bankers Trust Company from time to time, plus 1.5% or (ii) the
"Eurodollar Rate," plus 2.5%, and are payable upon the earlier of a "Change of
Control Event" or January 16, 1998. The Company may use the Facility to provide
financing for general corporate and working capital purposes including, subject
to the terms and conditions set forth in the Credit Agreement, establishment by
the Company of Affiliated Groups and acquisitions by the Affiliated Groups of
physician practice groups.

     The Loans are secured by all of the assets of the Company and its
subsidiaries, including subsequently created subsidiaries, and the receivables
of the Affiliated Groups, including the Flagship Affiliated Group and
subsequently created Affiliated Groups. The Loans are guaranteed by the Flagship
Affiliated Group and the Springfield Affiliated Group and must be guaranteed by
any subsequently created Affiliated Group.

     The Credit Agreement contains various representations and covenants of the
Company, including a covenant to maintain a minimum amount of accounts
receivable of the Affiliated Groups. Certain other covenants, among other
things, limit the ability of the Company or the Affiliated Groups to (i) amend
or terminate the Stockholders Agreement, the Services Agreements and certain
other agreements set forth in the Credit Agreement, (ii) make capital
expenditures, (iii) sell assets, (iv) incur additional debt, (v) make
investments or loans, (vi) pay dividends or distributions and (vii) issue
capital stock. In addition, the Company is required to maintain a minimum EBITDA
equal or exceeding a loss of $830,000 for the fiscal quarter ended March 31,
1997, a loss of $1.4 million for the six months ended June 30, 1997, a loss of
$1.5 million for the nine-months ended September 30, 1997 and a loss of $1.1
million for the year ended December 31, 1997. Failure to comply with such
covenants, as well as other events, including a payment default, a default under
certain agreements, a change in control, adverse judgments in excess of $25,000
and a default under any security documents constitute events of default under
the loans.

     In connection with the Credit Agreement, Bankers Trust received a
commitment fee of $157,500, which fee was converted into 63,000 shares of Class
A Common Stock on February 15, 1997.

Governmental Regulation

     As a participant in the healthcare industry, the Company's operations and
relationships, and the business and activities of its affiliated physicians,
will be subject to extensive and increasing regulation by a number of
governmental entities at the federal, state and local levels and by fiscal
intermediates appointed by various payors and other private brokers. The Company
will also be subject to laws and regulations relating to business corporations
in general. Because of the uniqueness of the structure of the relationship with
the physician groups, many aspects of the Company's business operations have not
been the subject of state or federal regulatory interpretation, and there can be
no assurance that a review of the business of the Company or its affiliated
physicians by courts or regulatory authorities will not result in a
determination that could adversely affect the operations of the Company or the
affiliated physicians. In addition, there can be no assurance that the
healthcare regulatory environment will not change so as to restrict the
Company's or the affiliated physicians' existing operations or their expansion.

     Prohibition on Corporate Practice of Medicine. The laws of most states,
including Massachusetts and Maryland, prohibit business corporations such as the
Company from practicing medicine or employing physicians to do so. The
contractual relationships the Company has entered into with the Affiliated
Groups attempt to comply with these laws. Because there is very limited judicial
or regulatory interpretation of the scope of the corporate practice of medicine
prohibition in most states, however, there can be no assurance that the
Company's contractual arrangements will be found to comply with such laws. Any
determination that the contractual relationships violate such laws could have a
material adverse effect on the Company, and there can be no assurance that the
Company would be able to restructure its arrangements on favorable terms or at
all.

     The BRM has proposed regulations that, if promulgated as proposed, might
prohibit physicians licensed within the Commonwealth of Massachusetts from
entering into management contracts with proprietary business entities unless a
majority of the governing board of those business entities are licensed
physicians and certain other conditions are met. The BRM also indicated that it
may seek to limit significantly the extent to which proprietary business
entities may have control or consultation rights with respect to medical
decisions or business decisions that may affect patient care, such as the amount
of time each physician spends with a patient. Extensive commentary has been
filed in opposition to the proposed regulations, and it is not known when or in
what form final regulations will be promulgated. The final regulations may have
a material adverse effect on the Company's relationship with the Springfield
Affiliated Group and its ability to operate in Massachusetts as currently
contemplated. Comparable regulations have not been proposed in Maryland, but
there can be no assurance that such regulations will not be proposed or adopted.

     Restrictions on Referrals and Fee-Splitting. In addition to prohibiting the
practice of medicine, numerous states prohibit entities such as the Company from
engaging in certain healthcare-related activities such as fee-splitting with
physicians or from making referrals to entities in which the referring physician
has an ownership interest. For example, Maryland has enacted legislation that
significantly restricts patient referrals for certain services, and requires
disclosure of ownership in businesses to which patients are referred and places
other regulations on healthcare providers. The Company has structured its
arrangements with the practices in the Flagship Affiliation to fit within the
group practice exemption contained in the Maryland act; however, investments or
contractual relationships with businesses not specifically operated by the
Flagship Affiliated Group would, in some cases, be prohibited. The Company
believes it is likely that other states will adopt similar legislation.
Accordingly, expansion of the operations of the Company to certain jurisdictions
may require it to comply with such jurisdictions' regulations which could lead
to structural and organizational modifications of the Company's anticipated form
of relationships with physician groups. Such changes, if any, could have an
adverse effect on the Company.

     Certain provisions of the Social Security Act, commonly referred to as the
"Anti-kickback Statute," prohibit the offer or receipt of any form of
remuneration in return for the referral of Medicare or state health

                                       29
<PAGE>
 
program (such as Medicaid) patients, or in return for the recommendation,
arrangement, purchase, lease, or order of items or services that are covered by
Medicare or state health programs. The Anti-kickback Statute is broad in scope
and has been broadly interpreted by courts in many jurisdictions. Read
literally, the statute places at risk many customary business arrangements,
potentially subjecting such arrangements to lengthy, expensive investigations
and prosecutions initiated by federal and state governmental officials. Many
states have adopted similar prohibitions against payments intended to induce
referrals of state health program and other third-party payor patients. While
the Company has attempted to structure its contractual relationships so as to
comply with the Anti-kickback Statute, there can be no assurance that such
relationships do in fact comply with the Anti-kickback Statute given the broad
wording of the statute. While the federal government has promulgated or proposed
various "safe harbor" exceptions to the Anti-kickback Statute, the Company does
not expect its operations to fit within any of the safe harbors. Violation of
the Anti-kickback Statute is a felony, punishable by fines up to $25,000 per
violation and imprisonment for up to five years. In addition, the Department of
Health and Human Services may impose civil penalties excluding violators from
participation in Medicare or state health programs.

     Significant prohibitions against physician referrals were enacted by
Congress in the Omnibus Budget Reconciliation Act of 1993. These prohibitions,
commonly known as "Stark II," amended prior physician self-referral legislation
known as "Stark I" by dramatically enlarging the field of physician-owned or
physician-interested entities to which the referral prohibitions apply. Stark II
prohibits, subject to certain exemptions, a physician or a member of his or her
immediate family from referring Medicare or state health program patients for
"designated health services" to an entity in which the physician has an
ownership or investment interest or with which the physician has entered into a
compensation arrangement including the physician's own group practice. The
designated health services include radiology and other diagnostic services,
radiation therapy services, physical and occupational therapy services, durable
medical equipment, parenteral and enteral nutrients, equipment, and supplies,
prosthetics, orthotics, outpatient prescription drugs, home health services, and
inpatient and outpatient hospital services. The penalties for violating Stark II
include a prohibition on payment by these government programs for services
rendered pursuant to such references and civil penalties of as much as $15,000
for each violative referral and $100,000 for participation in a "circumvention
scheme." In addition, the provider may be disqualified from participating in the
Medicare and state health care programs based on the submission of a false claim
or participation in a circumventive scheme. The Company has attempted to
structure its activities in compliance with Stark I and Stark II. However, the
Stark legislation is broad and the Stark I regulations are complex and do not
provide clear guidance on how Stark II will be interpreted. A finding that the
Company or its Affiliated Groups has violated Stark could have a material
adverse effect on the Company. In addition, future regulations or clarification
of the existing regulations could require the Company to modify the form of its
relationships with physician groups and may limit the Company's ability to
implement fully its plan for integrated care.

     Prohibition on False Claims. There are also state and federal civil and
criminal statutes imposing substantial penalties, including civil and criminal
fines and imprisonment, on healthcare providers who fraudulently or wrongfully
bill governmental or other third-party payors for healthcare services. The
federal law prohibiting false billings allows a private person to bring a civil
action in the name of the United States government for violations of its
provisions. There can be no assurance that the Company's activities will not be
challenged or scrutinized by governmental authorities. Moreover, technical
Medicare and other reimbursement rules affect the structure of physician billing
arrangements. Regulatory authorities might challenge the billing arrangements
with the Affiliated Groups and, in such event, the Company may have to modify
its relationship with physician groups. Noncompliance with such regulations may
adversely affect the operation of the Company and subject the Company and
Affiliated Groups to lost reimbursement, penalties and additional costs.

     Direct Provision of Healthcare Services. The Company plans to develop a
network of integrated healthcare services (other than acute care) in the future,
depending on market conditions. If the Company determines that it is
advantageous to provide such services through a wholly-owned subsidiary or other
controlled relationship, it is possible that one or more subsidiaries or
affiliates of the Company could become licensed providers of healthcare
services. Any such provider would have to comply with applicable regulatory

                                       30
<PAGE>
 
requirements. In addition, the direct provision of healthcare services by a
subsidiary or affiliate might increase the risk to the Company of regulatory or
other investigation or litigation.

     Healthcare Reform. A portion of the revenues of the Company's Affiliated
Groups is derived from payments made by governmental sponsored healthcare
programs (principally, Medicare and Medicaid). Government revenue sources are
subject to statutory and regulatory changes, administrative rulings,
interpretations of policy, determinations by fiscal intermediaries, and
government funding restrictions, all of which may materially decrease the rates
of payment and cash flow to physicians and other healthcare providers. The
federal Medicare program adopted a system of reimbursement of physician
services, known as the resource based relative value scale schedule ("RBRVS"),
which took effect in 1992 and is expected to be fully implemented by December
31, 1996. The Company expects that the RBRVS fee schedule and other future
changes in Medicare reimbursement will, in some cases, result in a reduction
from historical levels in the per patient Medicare revenue received by certain
of the Affiliated Groups with which the Company may contract, which in turn may
result in a decrease in revenues to the Company.

     In addition to current regulation, the United States Congress has
considered various types of healthcare reform, including comprehensive revisions
to the current healthcare system. It is uncertain what legislative proposals
will be adopted in the future, if any, or what actions federal or state
legislatures or third party payors may take in anticipation of or in response to
any healthcare reform proposals or legislation. Healthcare reform legislation
adopted by Congress could result in lower payment levels for the services of
physicians managed by the Company and lower profitability of the Affiliated
Groups, which could have a material adverse effect on the operations of the
Company.

     Insurance Laws. Laws in all states regulate the business of insurance and
the operation of HMOs. Many states also regulate the establishment and operation
of networks of healthcare providers. While these laws do not generally apply to
the hiring and contracting of physicians by other healthcare providers, there
can be no assurance that regulatory authorities of the states in which the
Company operates would not apply these laws to require licensure of the
Company's operations as an insurer, as an HMO or as a provider network.

     Antitrust Laws. Because the affiliated practice groups are not subsidiaries
of the Company and thus remain separate legal entities for antitrust purposes,
they may be deemed competitors subject to a range of antitrust laws which
prohibit anti-competitive conduct, including price fixing, concerted refusals to
deal and division of market. The Company intends to comply with such state and
federal laws as they may affect its development of integrated healthcare
delivery networks, but there is no assurance that the review of the Company's
business by courts or regulatory authorities will not result in a determination
that could adversely affect the operation of the Company and its affiliated
physician groups.

Competition

     The Company faces competition for both the recruitment and retention of
affiliated physicians. The market for affiliation with physicians is highly
competitive, and the Company expects this competition to increase. The Company
competes for physician affiliations with many other entities, some of whom have
substantially greater resources, greater name recognition and a longer operating
history than the Company and some of whom offer alternative affiliation
strategies which the Company may not be able to offer.

     The provision of physician practice management services is a highly
competitive business in which the Company will compete for contracts with
several national and many regional and local providers of such services. Certain
of the Company's competitors will have access to substantially greater resources
than the Company. Although the nature of the competition may vary, competition
is generally based on cost and quality of care.

                                       31

Facilities

     The Company leases a 6,358 square foot facility in Waltham, Massachusetts
for its headquarters and also leases office space in Springfield, Massachusetts
and Baltimore, Maryland. The Company also leases premises used by the
Springfield and Flagship Affiliated Groups.

Employees

     As of March 31, 1997, the Company had 34 employees and the Affiliated
Groups had 553 employees, including 98 physicians.

Employment Agreements

      The Company has entered into the following employment agreements with
Jerilyn P. Asher and Arlan F. Fuller.

      The Company is a party to an employment agreement with Ms. Asher pursuant
to which Ms. Asher serves as Chief Executive Officer of the Company for the
three-year period ending June 21, 1998. The term of the agreement will be
automatically extended for successive one-year terms, unless the Company
notifies Ms. Asher to the contrary at least 90 days prior to the expiration of
the then current term. For her services, Ms. Asher is entitled to an initial
base salary of $250,000 per year (subject to periodic increases as determined by
the Board) and is eligible to receive bonuses under the Company's management
incentive program, if such a program is adopted, in an amount up to 100% of her
base pay based upon individual and Company performance. Pursuant to an amendment
to the employment agreement dated August 30, 1996, Ms. Asher waived the right to
receive any unpaid amounts of base salary and bonus to which she was entitled
and had not received as of August 1, 1996. Ms. Asher is also entitled to receive
other benefits available to the Company's senior management generally. Pursuant
to a stock restriction agreement executed as of the date of the employment
agreement, the Company issued 4,162,500 shares of Series A Common Stock to Ms.
Asher at a purchase price of $.01 per share, 693,750 (50% of which vest on June
1997 and 50% in June 1998) of which remain subject to vesting based on duration
of employment, which vesting will be accelerated in the event of a Change in
Control. A Change in Control is defined to include a person or group becoming
the beneficial owner of 50% or more of the outstanding voting securities of the
Company, certain changes to the composition of the Board of Directors, certain
mergers and a liquidation of the Company. A percentage of the vested shares (50%
in the case of termination for cause and 35% in the case of voluntary
termination) are subject to the Company's repurchase rights in certain
circumstances, including termination of Ms. Asher for "cause" or Ms. Asher's
voluntary resignation, at the fair market value at the time of repurchase.

      The Company may terminate Ms. Asher's employment at any time without cause
and upon 10 days' written notice with cause. Ms. Asher may terminate her
employment for any reason upon 90 days' written notice. If Ms. Asher's
employment is terminated by the Company without cause, or if Ms. Asher
terminates her employment for good reason, the Company must pay Ms. Asher an
amount equal to two times her annual salary. Cause, for purposes of the
termination provisions, means willful and continued failure to perform her
duties, willful engagement in misconduct materially injurious to the Company or
her conviction for a felony, fraud or embezzlement of the Company's property. In
addition, the Company must also make such payment if Ms. Asher's employment is
terminated at any time within 24 months after a "Change in Control" for any
reason other than (i) death or disability, (ii) by the Company for Cause or
(iii) by Ms. Asher other than for Good Reason.

      During the term of the agreement, the Company must nominate Ms. Asher to
and Ms. Asher will be eligible to serve on the Board of Directors. Ms. Asher
also agreed to standard non-competition and non-disclosure terms with the
Company.

      The Company is also party to an employment agreement with Dr. Fuller,
pursuant to which Dr. Fuller serves as Executive Vice President, Medical
Information Systems and Academic Development of the Company for the three-year
period ending June 20, 1998. The term of the agreement will be automatically
extended for successive one-year terms, unless the Company notifies Dr. Fuller
to the contrary at least 90 days prior to the expiration of the then current
term. Dr. Fuller was required to devote 40% of his time to the Company and, for
such services, was entitled to an initial base salary of $175,000 per year
(subject to

                                       36
<PAGE>
 
periodic increases as determined by the Board). Dr. Fuller reduced his base
annual salary to $50,000 beginning in December 1996. Pursuant to a stock
restriction agreement executed as of the date of the employment agreement, the
Company issued 618,750 shares of Common Stock to Dr. Fuller at a purchase price
of $.01 per share. These shares are subject to vesting based on individual
performance and duration of employment, which vesting will be accelerated in the
event of a "Change in Control." The Company may terminate Dr. Fuller's
employment at any time with cause and upon 60 days' notice without cause. Dr.
Fuller may terminate his employment for any reason upon 60 days' written notice.

      During the term of the agreement, the Company must nominate Dr. Fuller to
and Dr. Fuller will be eligible to serve on the Board of Directors. Dr. Fuller
also agreed to standard non-competition and non-disclosure terms with the
Company.

Compensation Committee Interlocks and Insider Participation

      The Compensation Committee of the Board of Directors generally consists of
two non-employee directors, Dr. Fang is currently the only member. The
Compensation Committee makes recommendations to the Board of Directors
concerning salaries and incentive compensation for employees of and consultants
to the Company. No interlocking relationships exists between any member of the
Compensation Committee and any member of any other company's board of directors
or compensation committee.

1995 Equity Incentive Plan

      The Company's 1995 Equity Incentive Plan (the "1995 Plan") was adopted by
the Board of Directors and approved by the stockholders of the Company in June
1995. The 1995 Plan provides for the grant of stock options and the issuance of
shares of restricted stock to employees, officers and directors of, and
consultants or advisers to, the Company and its subsidiaries. Under the 1995
Plan, the Company may grant options that are intended to qualify as incentive
stock options within the meaning of Section 422 of the Internal Revenue Code of
1986, as amended (the "Code") ("incentive stock options"), or options not
intended to qualify as incentive stock options ("non-statutory options").
Incentive stock options may only be granted to employees of the Company.

      A total of 1,875,000 shares of Common Stock (adjustable up or down in
response to a change in the number of outstanding shares of Common Stock due to
any merger, consolidation, reorganization, recapitalization, reclassification,
stock dividend, stock split or other similar transaction) may be issued under
the 1995 Plan. In the event that additional securities of the Company are to be
issued in connection with future affiliation transactions, the Company may
initially use such authorized but unissued shares. The maximum number of shares
with respect to which options or awards may be granted to any employee under the
1995 Plan in any calendar year shall not exceed 500,000 shares of Common Stock.
Additionally, for so long as the Code shall so provide, incentive stock options
granted to an employee under the 1995 Plan will not, in any calendar year, have
an aggregate fair market value of more than $100,000. If not previously
terminated, the 1995 Plan will terminate on June 20, 2005 and options still
outstanding at that time will continue to have force and effect in accordance
with the provisions of the instruments evidencing such options.

      The 1995 Plan is administered by the Board of Directors whose duties are
delegable to a committee. Subject to the provisions of the 1995 Plan, the Board
of Directors has the authority to select the employees to whom options are
granted and awards of restricted stock are made and determine the terms of each
option or award, including (i) the number of shares subject to the option or
award, (ii) the vesting schedule of the option or award, (iii) the option
exercise price, which, in the case of incentive stock options, must be at least
100% (110% in the case of incentive stock options granted to a shareholder
owning in excess of 10% of the Company's Common Stock) of the fair market value
of the Common Stock as of the date of grant, and (iv) the duration of the option
(which, in the case of incentive stock options, may not exceed five years if
granted to a shareholder owning in excess of 10% of the Company's Common Stock
or ten years for all other recipients). As a condition to the grant of an option
under the 1995 Plan, each recipient of an option must execute an option
agreement, which may differ among recipients. The 1995 Plan may be modified,
amended or terminated at any time by the Board of Directors but such a
modification, amendment or termination will

                                       37
<PAGE>
 
not, without the consent of the optionee or recipient affect his or her rights
under any option or award previously granted to him or her. In addition, the
Board of Directors may, in its sole discretion (i) include additional provisions
in any option or award granted or made under the 1995 Plan (including
restrictions on transfer, repurchase rights, commitments to pay cash bonuses, to
make or guarantee loans or to transfer other property to optionees upon exercise
of options, or such other provisions as may be determined by the Board of
Directors) so long as such provisions are not inconsistent with the 1995 Plan or
applicable law and (ii) accelerate or extend dates on which options granted
under the 1995 Plan may be exercised.

      Payment of the option exercise price may be made in cash and/or Common
Stock or by any other method (including delivery of a promissory note payable on
terms approved by the Board of Directors and consistent with Section 422 of the
Code, Rule 16b-3 under the Securities Exchange Act of 1934, as amended, and
Regulation T promulgated by the Federal Reserve Board). Options are not
assignable or transferable except by will or the laws of descent and
distribution and, in the case of non-statutory options, pursuant to a qualified
domestic relations order (as defined in the Code).

      As of March 31, 1997, the Company had 34 employees, all of whom were
eligible to participate in the 1995 Plan. As of March 31, 1997, options to
purchase an aggregate of 574,836 shares of Common Stock were outstanding
pursuant to the 1995 Plan.

                              CERTAIN TRANSACTIONS

      As of March 31, 1997, pursuant to the Bain Financing, the Institutional
Investors purchased an aggregate of 4,000,000 shares of Class B Common Stock and
warrants exercisable for 5,549,500 shares of Class B Common Stock for an
aggregate purchase price of $10,000,000. See "Business -- The Bain Financing."
In connection with the Bain Financing, the Company entered into a Management
Agreement dated as of August 30, 1996 with BCP V, pursuant to which the Company
will pay BCP V (or an affiliate designated by BCP V) a management fee of
$500,000 per year, plus 1% of any financings from parties other than affiliates
of Bain Capital, for services including advice in connection with financings and
financial, managerial and operational advice in connection with day-to-day
operations (the "Management Agreement"). The Company is also obligated to pay
certain expenses, not to exceed $100,000 per year without the Company's consent,
of BCP V, Bain Capital and the Institutional Investors in connection with the
Management Agreement. Each of Stephen G. Pagliuca and Marc Wolpow is a Director
of the Company, a limited partner of BCP V, which is the general partner of Bain
Capital Fund V, L.P. and Bain Capital Fund V-B, L.P., and a general partner of
BCIP Associates, L.P. and BCIP Trust Associates, L.P., and a Managing Director
of Bain Capital, which manages each of the Institutional Investors.

      Alphonse Calvanese, M.D., is a director of the Company and transferred his
practice to the Springfield Affiliated Group for which he received his allocable
portion of the $11.8 million total consideration paid to the physicians who
transferred their practices to the Springfield Affiliated Group.

      Ira Fine, M.D. and Dana Frank, M.D., each a Director of the Company, are
members of medical practice groups which transferred their practice assets to
the Flagship Affiliated Group in the Flagship Affiliation. Upon consummation of
the Flagship Affiliation, Dr. Fine received his allocable share of the total
consideration of $566,580 payable to his existing practice group, and Dr. Frank
received his allocable share of the total consideration of $3,647,064 payable to
his existing practice group.

                              PLAN OF DISTRIBUTION

      Shares of Common Stock will be offered in connection with PQC's (or a
subsidiary's) acquisition of businesses, properties or equity and/or debt
securities in business combination transactions from time to time. A maximum of
8,000,000 shares of Common Stock may be issued and sold pursuant to this
Prospectus. These shares will ordinarily represent consideration paid directly
upon the acquisition of businesses, properties or securities, in some cases
together with additional consideration consisting of cash, debt or other
securities

                                       38
<PAGE>
 
(which may be convertible into shares covered by this Prospectus) or assumption
by the Company of liabilities of the businesses being acquired, or a combination
thereof. The shares may also include shares to be delivered upon the exercise or
satisfaction of conversion or purchase rights which are created in connection
with acquisitions or which were previously created or assumed by the companies
whose businesses or properties are acquired by PQC (or a subsidiary).

                                    DILUTION

      Jerilyn Asher, the Chief Executive Officer, Arlan Fuller, M.D., a
director, and Jay Greenberg, a former Executive Vice President of the Company,
received restricted stock grants of 4,162,500, 618,750 and 1,012,500 shares,
respectively, in connection with the formation of the Company and their
employment agreements. Such stock is subject to vesting and partial forfeiture
in certain circumstances, including termination of employment with the Company.
The purchase price of the restricted stock was $0.01 per share. Officers and
employees of the Company have also received, as of March 31, 1997, options to
purchase an aggregate of 574,836 shares of Class A Common Stock at a weighted
average exercise price of $0.49 per share. Other non-employees hold additional
options to purchase 17,500 shares of Class A Common Stock with an exercise price
of $0.85 per share. All other options or shares of the Company's outstanding
Class A and Class B Common Stock were issued at prices between $2.40 and $2.50
per share. Since there is no public market for the Class A Common Stock, future
issuance of the Common Stock (except for shares issued pursuant to the Bain
Financing and related warrants which provided for the purchase of shares,
subject to adjustment to prevent dilution, of $2.50 per share) will be issued at
prices negotiated with physicians affiliating with the Company and determined to
reflect fair value at the time of issuance by the Board of Directors. The net
tangible book value per share at December 31, 1996 was $1.31. The offering price
for the Common Stock in the offering has not yet been determined but is expected
to be substantially in excess of the net tangible book value per share before
and immediately after such sale.

of Preferred Stock, $.01 par value per share, and 100,000,000 shares of common
stock, $.01 par value per share, of which (i) 75,000,000 shares are designated
as Class A Common Stock, (ii) 15,267,915 shares are designated as Class B-1
Common Stock, and (iii) 9,732,085 shares are designated as Class B-2 Common
Stock. As of March 31, 1997, there were issued and outstanding (i) 20,071,614
shares of Class A Common Stock held by approximately 160 stockholders and (ii)
2,442,866 shares of Class B-1 Common Stock and 1,557,134 shares of Class B-2
Common Stock held by 4 stockholders. There were no outstanding Shares of
Preferred Stock.

Class A Common Stock and Class B Common Stock

     Except as otherwise provided below, all shares of Class A Common Stock and
Class B Common Stock are identical in all respects and entitle the holders
thereof to the same rights, privileges and preferences and are subject to the
same qualifications, limitations and restrictions. Holders of the Class A Common
Stock and the Class B Common Stock are entitled to one vote per share with
respect to all matters to be voted on by the stockholders of the Company and do
not have cumulative voting rights. There are no sinking fund provisions with
respect to any of the Company's Class A Common Stock or Class B Common Stock. No
distribution (whether in cash, securities or otherwise) may be made in respect
of either the Class A Common Stock or the Class B Common Stock unless an
equivalent distribution is made with respect to each outstanding share of the
other class.

     Class B Common Stock. Shares of Class B Common Stock are convertible into
shares of Class A Common Stock at the option of the holder, and automatically
convert into shares of Class A Common Stock upon the earlier of a "Qualified
Public Offering" or a reduction in the number of shares of Class B Common Stock
below certain thresholds. A "Qualified Public Offering" is a public offering (i)
in which the net proceeds of the sale of such shares by the Company and any
stockholder of the Company equal or exceed $50,000,000, provided that the net
proceeds of the sale thereof to the Institutional Investors equal or exceed the
greater of (x) fifty percent of the purchase price paid by the Institutional
Investors in any closing under the Bain Purchase Agreement or (y) $10,000,000;
and (ii) involving a firm commitment underwriting by a nationally recognized
underwriter acceptable to the Class B Directors (as defined below). In any such
conversion, each outstanding share of Class B Common Stock converts into the
number of shares of Class A Common Stock determined by application of the
conversion ratio (the "Class B Conversion Factor") in effect, which was one as
of March 31, 1997, subject to adjustment in order to reflect any stock
dividends, stock splits, reverse stock splits, reorganizations or
recapitalizations of the Company's capital stock.

      Subject to the special voting rights of the Class B Directors and the
approval rights of the Institutional Investors described below, the Board of
Directors of the Company may, at any time, without any vote of the holders of
the Company's capital stock, issue all or any part of the unissued capital stock
of the Company from time to time authorized under the Restated Certificate and
may determine, subject to any requirements of law, the consideration for which
such stock is to be issued and the manner of allocating such consideration
between capital and surplus.

      Election of Directors. The holders of the Class A Common Stock, voting
separately as a single class, are entitled to elect two of the eleven directors
of the Company (each, a "Class A Director"), there currently being one vacancy.
Any vacancy in the seats held by the Class A Directors shall be filled only by
vote of a majority of the outstanding shares of Class A Common Stock, and no
Class A Director may be removed without the consent of a majority of the holders
of the Class A Common Stock. The Company may not in any manner subdivide or
increase (by stock split, stock dividend or other similar manner) reclassify or
combine in any manner the outstanding shares of Class A Common Stock unless a
proportional adjustment is made to the Class B Conversion Factor.

                                       42
<PAGE>
 
      The holders of the Class B-1 Common Stock, voting separately as a single
class, are entitled to elect one of the eleven directors of the Company, the
Class B-1 Director and the holders of the Class B-2 Common Stock, voting
separately as a single class, are entitled to elect one director of the Company,
the Class B-2 Director. Any vacancy in the seats held by the Class B Directors
shall be filled only by vote of a majority of the outstanding shares of Class B-
1 Common Stock or Class B-2 Common Stock, as applicable, and no Class B Director
may be removed without the consent of a majority of the holders of the Class B-1
Common Stock or Class B-2 Common Stock, as applicable. The Company may not in
any manner subdivide or increase (whether by stock split, stock dividend or
other similar manner), reclassify or combine in any manner the outstanding
shares of the Class B Common Stock unless a proportional adjustment is made to
the Common Stock.

     The holders of the Class A Common Stock and the Class B Common Stock,
voting together as a single class, are entitled to elect seven of the eleven
directors of the Company (each, a "Class A/Class B Common Stock Director"). Any
vacancy in the seats held by the Class A/Class B Common Stock Directors shall be
filled only by vote of a majority of the outstanding shares of Common Stock and
Class B Common Stock, and no Class A/Class B Common Stock Director may be
removed without the consent of a majority of the holders of the Class A Common
Stock and Class B Common Stock. Except as provided below, each director of the
Company is entitled to one vote on all matters to be voted on by the directors,
and the directors vote together as a single class on all matters.

     Pursuant to the Stockholders Agreement, the Institutional Investors and the
Class A Common Stockholders who are parties to such agreement are required to
elect as Class A Directors two individuals who are employees of the Company and
are selected by the Chief Executive Officer and seven other Directors who are
physicians and are selected by the Chief Executive Officer and approved by the
Institutional Investors. See " -- Stockholders' Agreement."

     Special Rights of Class B Directors. The Class B Directors are entitled to
one vote on any matter before the Board of Directors, except that each Class B
Director is entitled to five votes (providing the Class B Directors with a
majority of the voting power of the Board) (i) with respect to any Class B
Director Action and (ii) with respect to all matters in the event that any Class
B Director Control Event remains uncured.

     "Class B Director Actions" include (i) the issuance, redemption or similar
disposition of capital stock or securities convertible into capital stock of the
Company or any of its subsidiaries or affiliates (including its Affiliated
Groups), (ii) the declaration of dividends or other distributions in respect of
the capital stock of the Company or any of its subsidiaries or affiliates
(including its Affiliated Groups), (iii) the incurrence of indebtedness by the
Company or any of its subsidiaries or the incurrence of material indebtedness by
any of its affiliates (including its Affiliated Groups), (iv) a merger, sale,
liquidation or similar transfers involving the Company or any of its
subsidiaries or affiliates (including its Affiliated Groups), (v) public
offerings, (vi) material amendments to any management or similar agreement by
the Company or any of its subsidiaries with its affiliates (including its
Affiliated Groups) or with the shareholder of any of its Affiliated Groups and
(vii) the employment, termination and compensation of the Chief Executive
Officer.

     "Class B Director Control Event" means any of the following: (i) the
Company fails to achieve earnings before interest, taxes, depreciation and
amortization ("EBITDA") targets, which targets increase quarterly; (ii) the
Company fails to achieve minimum net sales levels, which levels increase
quarterly; (iii) Jerilyn Asher is no longer employed on a full time basis as
Chief Executive Officer for any reason other than her employment having been
terminated without Cause (as defined in the Restated Certificate) or (iv) the
Company shall have taken a "Restricted Action" (as described below) without the
prior approval of the Institutional Investors. The EBITDA and net sales targets
are the same as set forth under "Business -- Bain Financing" as conditions for
the commitments of the Institutional Investors.

     Certain "Restricted Actions," in addition to being approved by the Board of
Directors, must be approved by the Institutional Investors. Restricted Actions
include (without limitation) (i) a merger, sale, liquidation or

                                       43
<PAGE>
 
similar transaction involving disposition of all, substantially all, or a
material part of, the property, business or assets of the Company or any of its
subsidiaries or affiliates (including its Affiliated Groups), (ii) any agreement
by the Company or any of its subsidiaries or affiliates (including its
Affiliated Groups) for an acquisition or affiliation transaction (other than
acquisitions or affiliations not in excess of $1 million in any 12-month
period), (iii) dividends and other distributions by the Company or any of its
subsidiaries, (iv) any material change in the business of the Company or any of
its subsidiaries or affiliates (including its Affiliated Groups), (v) any
amendment to the charter or by-laws of the Company or its subsidiaries, (vi)
retention or dismissal of the Chief Operating Officer or Chief Financial Officer
of the Company, (vii) transactions by the Company or any of its subsidiaries
with affiliates (including its Affiliated Groups) and (viii) commencement and
management of any material litigation.

     The Restated Certificate provides that upon conversion of all outstanding
shares of Class B Common Stock into Common Stock, the holders of the Common
Stock will be entitled to elect all the directors, each director will have one
vote on all matters to be voted on by the directors, and the provisions therein
granting the Class B Directors special voting rights will be eliminated.

     Other Obligations. Under the Bain Purchase Agreement, the Company has
certain other obligations relating to its capital stock that are not reflected
in the Restated Certificate. Subject to certain conditions, the Bain Purchase
Agreement requires that the Company provide the Institutional Investors with an
opportunity to participate in future financings by the Company involving debt or
equity securities in lieu of and on the same conditions as other potential
investors. The Agreement, independently from the Restated Certificate, also
requires that the Company not engage in any Restricted Action without the prior
approval of the Institutional Investors. Both of these obligations terminate
only upon a Qualified Public Offering.

     Certain Corporate Provisions. The Restated Certificate authorizes
10,000,000 shares of Preferred Stock and grants the Board of Directors the
authority to issue series of Preferred Stock with such voting rights and other
powers as the Board of Directors may determine (subject to the special voting
rights of the Class B Directors and the approval rights of the Institutional
Investors). Those provisions, as well as the voting rights of the Class B
Directors and the approval rights of the Institutional Investors, may be deemed
to have an "anti-takeover" effect in that they may delay, defer or prevent a
change of control of the Company.

Preferred Stock

     The Board of Directors is authorized, subject to any limitations prescribed
by law, without further stockholder approval, to issue from time to time up to
an aggregate of 10,000,000 shares of preferred stock, in one or more series.
Each such series of preferred stock shall have such number of shares,
designations, preferences, voting powers, qualifications and special relative
rights or privileges as shall be determined by the Board of Directors, which may
include among others, dividend rights, voting rights, redemption and sinking
fund provisions, liquidation preferences, conversion rights and preemptive
rights.

     The stockholders of the Company have granted the Board of Directors
authority to issue the preferred stock and to determine its rights and
preferences in order to eliminate delays associated with a stockholder vote on
specific issuances. The rights of the holders of Common Stock will be subject to
the rights of holders of any preferred Stock issued in the future. The issuance
of preferred stock, while providing desirable flexibility in connection with
possible acquisitions and other corporate purposes, could have the effect of
making it more difficult for a third party to acquire, or of discouraging a
third party from attempting to acquire, a majority of the outstanding voting
stock of the Company. The Company has no present plans to issue any shares of
preferred stock.

Warrants

     At March 31, 1997, the Company has issued Class B Warrants to acquire up to
5,549,500 shares of Class B Common Stock to the Institutional Investors at an
exercise price of $2.50 per share of Class B Common Stock. Pursuant to the Bain
Financing, the Company may be obligated to issue Class B Warrants to purchase an
additional 7,450,500 shares of Class B Common Stock. The Class B Warrants expire
on August 30, 2003. The number of shares of Class B Common Stock issuable upon
exercise and the exercise price are subject to adjustment to prevent dilution,
including adjustment in the event that any Class A Common Stock is issued at a
price less than Exercise Price. The Class B Warrants become warrants to purchase
Class A Common Stock at such time as the Class B Common Stock is converted to
Class A Common Stock. The Company has also issued warrants to purchase 853,076
shares of Class A Common Stock at $2.40 per share, of which 436,538 expire in
2000 and 416,538 expire in 2001, warrants to purchase 50,000 shares of Class A
Common Stock at $3.00 per share, all of which expire in 2003, and 201,150
warrants to purchase Class A Common Stock at $5.00 per share which expire in
2003.

Stockholders Agreement

     The Company, the Institutional Investors, management holders of the
Company's equity securities, the Flagship Stockholder Physicians, certain
Springfield physicians and all other holders of the Company's equity securities
(other than the Springfield Stockholder Physicians) are parties to the
Stockholders Agreement dated as of August 30, 1996. The 28 Springfield
Stockholder Physicians are parties to a separate stockholders agreement and
registration rights agreement described below. In addition, approximately 7
Flagship Shareholder Physicians nearing retirement age entered into an
additional agreement containing provisions with respect to the treatment of
Securities (as defined below) held by them at retirement.

     The Stockholders Agreement requires each Stockholder (as defined in the
Agreement) to vote his or her shares of the Company to elect as directors of the
Company: (i) two employees designated by the Chief Executive Officer, and (ii)
seven physicians designated by the Chief Executive Officer and approved by the
Institutional Investors. Pursuant to the Company's Restated Certificate, the
Institutional Investors have the right to designate the two other directors of
the Company. See "Description of Capital Stock."

     The Stockholders Agreement prohibits the transfer of shares of the Company
held by officers and employees (except shares issuable pursuant to certain
incentive stock options granted to employees) ("Management Shares") and options,
warrants and shares issued in affiliation transactions ("Physician Shares")
(collectively, "Restricted Shares") except under certain limited circumstances,
such as transfer of such Restricted Shares to members of the holder's immediate
family or to the holder's estate and heirs provided that they agree to become
bound by the Stockholders Agreement.

     Except with respect to Management Shares held by Ms. Asher, upon
termination of a holder's employment with the Company or an Affiliated Group,
the Company has the right to acquire Restricted Shares held by such holder,
together with any exercisable warrants or options held by such holder (such
warrants, options and Restricted Shares, collectively, "Securities") at fair
market value (or, in the event of termination for cause, at the lower of cost or
fair market value). Upon the death of any officer, employee or affiliated
physician, the estate of such holder has the right, subject to certain
limitations, to sell all or any part of the holder's Securities to the Company
at fair market value. The Stockholders Agreement also provides for certain take
along obligations pursuant to which, at the request of the Institutional
Investors, holders are required to sell a proportionate amount of their shares
to persons who are acquiring shares from the Institutional Investors on the same
terms and conditions. In addition, subject to certain conditions, all holders
have the right to join pro rata in any sale of shares by another holder.

     All holders have so-called "piggyback registration rights" which permit
them to cause the Company to use its best efforts to add their shares (subject
to certain limitations) to registration statements filed by the

                                       45
<PAGE>
 
Company under the Securities Act for any public offering, other than
registration statements pertaining to employee benefit plans or acquisitions.
The Institutional Investors have so-called "demand registration rights" which
permit them, subject to certain conditions, to cause the Company to use its best
efforts to effect a registration under the Securities Act of all or a part of
their shares. These demand registration rights may only be exercised with
respect to three such registrations. Each holder agrees that upon the request of
the underwriters managing any underwritten public offering of the Company's
securities, it will not transfer any shares for a period beginning not more than
seven days immediately preceding and ending not more than 180 days following the
public offering without the prior written consent of the underwriters.

     The Stockholders Agreement further provides that the Company shall not,
without the prior written consent of the Institutional Investors, enter into any
agreement with any holder or prospective holder of any securities of the Company
relating to registration rights unless such agreement (to the extent the
agreement would allow such holder or prospective holder to include such
securities in any registration filed under the provisions of the Stockholders
Agreement) includes a provision that such holder or prospective holder may
include such securities in any such registration only to the extent that the
inclusion of its securities will not (i) reduce the amount of the securities
held by the Institutional Investors which would otherwise be included in such
registration and (ii) otherwise diminish the rights provided in the Stockholders
Agreement.

     Subject to certain limited exceptions, each holder agrees that it will not
transfer any shares to any person unless such person has delivered to the
Company a written acknowledgment and agreement that the shares to be received
are subject to all of the provisions of the Stockholders Agreement and that such
person agrees to be bound by and party to the Agreement to the same extent as if
it were the original holder and an original signatory thereto.

     The Springfield Stockholder Physicians who entered into affiliation
transaction on August 30, 1996, are subject to a separate stockholders agreement
with the Company dated as of August 9, 1996 (the "Springfield Stockholders
Agreement"). The Springfield Stockholders Agreement provides that no Springfield
Stockholder Physician may transfer, assign or pledge his or her rights in shares
of the Company until August 9, 1998, unless the Company concludes that such
transfer will not prevent the merger pursuant to which such physician became
affiliated with the Company from qualifying as a tax free transaction. In
addition to that limitation, the Company has a right of first refusal for 60
days upon a Springfield Stockholder Physician's decision to transfer his or her
shares pursuant to which the Company must purchase all or none of such shares.
The Company's right of first refusal does not extend to transfers (i) pursuant
to a registration statement, (ii) as part of a sale of substantially all shares
of the Company, and (iii) to a family member, heir or entity controlled by the
physician. As a condition to each such exempt transfer, the transferee must
agree to be bound by the terms of the Springfield Stockholders Agreement. The
Company's right of first refusal terminates upon an initial public offering or
merger, sale of the Company, or similar transaction. The Company also has the
right to redeem the shares held by a physician at fair market value upon
termination of his or her employment for any reason prior to August 9, 1999. The
shares subject to the Springfield Stockholders Agreement are held in an escrow
account controlled jointly by the Company and each physician.

     The Springfield Stockholder Physicians who entered into affiliation
transaction on August 30, 1996, are also subject to a separate registration
rights agreement with the Company dated as of August 9, 1996 (the "Springfield
Registration Rights Agreement"). The Springfield Registration Rights Agreement
grants the Springfield Stockholder Physicians unlimited piggy-back registration
rights with respect to any registration statement (other than a registration
statement on Form S-8 or Form S-4) filed by the Company for a public offering,
except the registration statement relating to the initial public offering of the
Company's stock. The shares to be registered may be limited by the underwriters,
provided that the physicians who have elected to participate in the offering
will participate pro rata with all other holders registering shares. The
Springfield Registration Rights Agreement terminates on August 9, 1998.

                                       46
<PAGE>
 
     Pursuant to the Stockholders Agreement and the Springfield Registration
Rights Agreement, at March 31, 1997, 4,000,000 Class B Shares are entitled to
demand registration rights and all outstanding shares of Common Stock are
entitled to piggy-back registration rights.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Shares offered hereby may generally be resold by the persons acquiring them
without further registration under the Securities Act, unless such persons are
"affiliates" or "underwriters" within the meaning of the Securities Act.
However, it is expected that each future stockholder, including physicians
entering into affiliation transactions with the Company, will enter into a
Stockholders Agreement which impose certain restrictions upon the resale of
shares of the Company's Common Stock.

     At March 31, 1997, the Company had outstanding 24,071,614 shares of Class A
Common Stock and Class B Common Stock (before giving effect to any future
exercise of outstanding warrants and options). 1,666,151 shares of Class A
Common Stock are freely tradeable without restriction under Rule 144(k) of the
Securities Act. None of the outstanding shares of Class A Common Stock and Class
B Common Stock (collectively, the "Restricted Shares"), including Restricted
Shares to be issued in connection with the exercise of outstanding warrants and
options, have been registered under the Securities Act, and they may be resold
publicly only upon registration under the Securities Act or in compliance with
an exemption from the registration requirements of the Securities Act.

     At present, Rule 144 provides generally that if one year has elapsed since
the later of the date of the acquisition of Restricted Shares from the Company
or any affiliate of the Company, the acquiror or subsequent holder thereof may
sell, within any three-month period, a number of shares that does not exceed the
greater of 1% of the then outstanding shares of Common Stock or the average
weekly trading volume of the Common Stock during the four calendar weeks
preceding the date on which notice of the sale if filed with the Commission.
Sales under Rule 144 are also subject to certain manner of sale provisions,
notice requirements and the availability of current public information about the
Company. If two years have elapsed since the later of the date of acquisition of
Restricted Shares from the Company or from any affiliate of the Company, and the
acquiror or subsequent holder thereof is deemed not to have been an affiliate of
the Company at any time during the 90 days preceding a sale, such person would
be entitled to sell such shares without regard to the limitations described
above. As of March 31, 1997, holders of 14,313,295, 6,984,676, 440,000 and
667,493 Restricted Shares will be eligible to sell such shares pursuant to Rule
144 under the Securities Act, subject to the manner of sale, volume, notice and
information requirements of Rule 144, beginning in September 1997, December
1997, January 1998 and February 1998, respectively.

                                 LEGAL MATTERS

     The validity of the Common Stock offered hereby has been passed upon for
the Company by Hale and Dorr LLP, Boston, Massachusetts. As of the date of this
Prospectus, H&D Investments II, a general partnership in which certain members
of Hale and Dorr LLP are partners, beneficially owns 20,833 shares of the
Company's Class A Common Stock.

              Unaudited Pro Forma Combined Statement of Operations


     The Unaudited Pro Forma Combined Statement of Operations for the year ended
December 31, 1996 combine the historical results of PQC with the historical
results of the following entities, giving effect to the affiliation transactions
for each such entity as if it had occurred on January 1, 1996: Springfield
Medical Associates, Inc. ("SMA"); Alphonse F. Calvanese, M.D., Cardiology and
Internal Medicine Associates, Inc., James F. Haines and William J. Belcastro,
Partnership, Jay M. Ungar, M.D. and Western Massachusetts Medical Group, Inc.
(the "Remaining Springfield Practices"), and Annapolis Medical Specialists,
L.L.P., Drs. Fortier, Libber, Clemmens & Weimer, P.A., Drs. Goldgeier, Levine &
Friedman, P.A., Koeppel, Rosen, Rudikoff, M.D., P.C., Drs. Pakula, Davick &
Bogue, P.A., Park Medical Associates and Affiliate, and Drs. Sigler, Roskes,
Holden & Schuberth, P.A. (the "Specified Flagship Practices").

     The Specified Flagship Practices are only a portion of the practices that
constitute the Flagship Affiliation, and the Remaining Springfield Practices,
which along with SMA constitute the Springfield Affiliation, exclude one
practice.  In accordance with the regulations of the Securities and Exchange
Commission, the other practices which are part of those affiliations have not
been audited and accordingly have not been included in the pro forma financial
information.

     The Unaudited Pro Forma Combined Statement of Operations may not be
indicative of the results that actually would have resulted had the above
affiliations occurred as of the date indicated, or of future earnings or of the
future financial position of the Company.  The Unaudited Pro Forma Combined
Statement of Operations should be read in conjunction with the accompanying
Notes to the Unaudited Pro Forma Combined Statement of Operations and the
financial statements of the affiliated practices included elsewhere in this
Registration Statement and Prospectus.

         Notes To Unaudited Pro Forma Combined Statement of Operations


1.  Basis of Presentation

The Unaudited Pro Forma Combined Statement of Operations for the year ended
December 31, 1996 assumes that the affiliations with SMA, the Remaining
Springfield Practices and the Specified Flagship Practices were consummated on
January 1, 1996.


2.  Proforma Adjustments

(A) To adjust amounts retained by physician groups reflecting actual physician
    compensation based on employment agreements as if they were entered into on
    January 1, 1996.

(B) To reflect amortization of goodwill for the SMA and Remaining Springfield
    Practices' Affiliations.  The adjustment records amortization expense for
    the period January 1, 1996 through August 30, 1996, the Springfield
    Affiliation date.

(C) To reflect the annual management fee of $500,000 to Bain Capital.  The
    adjustment records  expense for the period January 1, 1996 through 
    August 30, 1996, the date of the SMA and Remaining Springfield Affiliations.

(D) To reflect amortization of goodwill for the Specified Flagship Practices.
    The adjustment records amortization expense for the period January 1, 1996
    through December 11, 1996, the Flagship Affiliation date.

(E) Reversal of income taxes recorded for PQC and the affiliated practices
    which include income taxes calculated at individual and corporate tax rates.
    No provision for income taxes is recorded in the unaudited pro forma
    statements of operations as operating losses from PQC would be significant
    to offset taxable income in the affiliated practices.

3.  Net Loss per Share and Supplemental Net Loss per Share

Net loss per share of common stock on a pro forma basis reflects the issuance of
2,592,245 shares of Class A common stock in connection with the SMA and
Remaining Springfield Affiliations, 6,842,675 shares of Class A common stock in
connection with the Specified Flagship Affiliations, and 4,000,000 shares of
Class B common stock in connection with the Bain Financing,  all at January 1,
1996.  The effect of options and warrants is not considered as their effect
would be antidilutive. Net loss available to common stock reflects an adjustment
to accrete common stock subject to put to fair value at December 31, 1996.

Supplemental net loss per share on a proforma basis for the year ended 
December 31, 1996 is as follows:

</TABLE>

   Supplemental net loss per share assumes the conversion of  1,666,151 shares
   of convertible preferred stock to common stock on a one for one basis, the
   conversion of a convertible promissory note payable into 625,000 shares of
   common stock and the conversion of a convertible bridge loan into 402,301
   shares of common stock,   all as of January 1, 1996. Supplemental net loss
   available to common stock excludes interest expense related to the
   convertible promissory note payable and the convertible bridge loan.

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.


We have audited the accompanying balance sheets of Physicians Quality Care, Inc.
(the Company) as of December 31, 1995 and 1996, and the related statements of
operations, changes in stockholders' equity (deficit) and common stock subject
to put, and cash flows for the period from March 20, 1995 (inception) to
December 31, 1995 and the year ended December 31, 1996.  These financial
statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our 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 Physicians Quality Care, Inc.
as of December 31, 1995 and 1996 and the results of its operations and its cash
flows for the period from March 20, 1995 (inception) to December 31, 1995 and
the year ended December 31, 1996, in conformity with generally accepted
accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern.  As discussed in Note 2 to the
financial statements, the Company's ability to continue as a going concern will
be dependent upon obtaining adequate financing and consummating future
affiliations with physician practices.  In addition, the recoverability of
assets and payment of liabilities will be dependent upon the Company's ability
to continue as a going concern.  These uncertainties raise substantial doubt
about the Company's ability to continue as a going concern.  The financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

                         Notes to Financial Statements

                               December 31, 1996



1. Business and Organization

Formed in March 1995, Physicians Quality Care, Inc. (PQC or the Company)
provides complete practice management for multi-specialty medical practice
groups.  The Company's objective is to establish and manage networks of
specialty and primary care physicians and related diagnostic and therapeutic
support services which can provide comprehensive health care services in
targeted geographic areas.

On August 30, 1996, the Company consummated affiliations with seven physician
practices (32 physicians and a physician-owned laboratory) in Springfield,
Massachusetts, and on December 11, 1996, the Company consummated affiliations
with fifteen physician practices (59 physicians and a physician-owned
laboratory) in the Baltimore/Annapolis, Maryland area.  As of the date of the
affiliations the Company began providing management services to the physicians
under long-term management agreements and recognizing revenues from these
physician practices (the Physician Practices).  Prior to August 30, 1996, the
Company's operations consisted primarily of seeking affiliations with physician
practices and negotiating the terms of the affiliations and management
agreements with such physician practices.

2. Operations and Basis of Presentation

The accompanying financial statements have been prepared assuming the Company
will continue as a going concern. Since its inception, the activities of the
Company have been primarily devoted to seeking affiliations with physician
practices, negotiating the terms of the affiliations with and management
agreements with, physician practices. The Company consummated affiliations with
91 physicians during 1996, the terms of which are more fully disclosed in Note
4. Due to the absence of significant revenues prior to the affiliations, the
Company has predictably incurred significant operating losses and currently does
not have working capital available to fund its growth strategy or operating
losses expected during the next year. These conditions raise substantial doubt
about the Company's ability to continue as a going concern.

Management expects to finance its future affiliations with sales of equity
pursuant to existing financing agreements with its Institutional Investors (see
Note 10). In addition, management expects to fund operations in the short term
with proceeds of an equity offering to private investors and a working capital
line of credit (see Note 13) and with management fee income and positive cash
flow from existing physician practices. However, no assurances can be provided
that the Company will successfully complete these financings. Should any of the
planned financing not be completed, management

                                                                               6

2. Operations and Basis of Presentation (continued)

will seek financing through other sources; however, there can be no assurance
that other sources of capital will be available on terms and conditions
acceptable to the Company or at all. The financial statements do not include any
adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.

3. Summary of Significant Accounting Policies

Basis of Presentation

The financial statements have been prepared on the accrual basis of accounting.
The Company enters into long-term affiliation arrangements with physician
practices, and through mergers and asset purchases, the assets and liabilities
of the physician practices are transferred to a professional corporation
affiliated with the Company. The Company does not consolidate the operating
results and accounts of the physician practices. For display purposes, the
Company has presented the physician practice revenues and amounts retained by
the physician practices in the accompanying statements of operations to arrive
at the Company's gross management fee revenue. See further discussion below.

Net Patient Service Revenue

Net patient service revenue represents the revenue of the physician practices
reported at the estimated realizable amounts from patients, third-party payors
and others for services rendered, net of contractual and other adjustments.

During 1996, the Company estimates that approximately 40% of net patient service
revenue was received under government-sponsored healthcare programs
(principally, the Medicare and Medicaid programs).

The Company has agreements with various Health Maintenance Organizations (HMOs)
to provide medical services to subscribing participants. Under these agreements,
the Company receives monthly capitation payments based on the number of each
HMO's participants.

                                                                               7

3. Summary of Significant Accounting Policies (continued)

Management Fee Revenue

Management fee revenue represents net patient service revenue less amounts
retained by physician practices.  The amounts retained by physician practices
represents amounts paid to the physicians pursuant to the service agreements
between the Company and the physician practices, consisting of (a) baseline
compensation which is a significant percentage (80% to 95%) of the physicians'
historic compensation levels, and (b) an allocation of the physician practices'
net profits after payment of operating expenses and compensation to physicians.
Under the service agreements, the Company provides each physician practice with
a comprehensive package of services, including office and facilities, equipment,
nursing and other non-physician professional support, administrative support,
information systems, comprehensive professional liability insurance, and general
management and financial advisory services.  The Company also bills all
patients, insurance companies and third-party payors and negotiates all
contracts and relationships with payors.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of three
months or less at the time of purchase to be cash equivalents.  The carrying
amount reported in the balance sheet for cash and cash equivalents approximates
its fair value.

Property and Equipment

Property and equipment is carried at cost.  Depreciation is calculated using the
straight-line method over the useful lives of the assets.

Professional Liability Insurance

The Company has obtained professional liability coverage for the Physician
Practices through commercial insurance carriers on either a claims-made or
occurrence basis.  The Company has purchased additional insurance to cover the
tail portion of the claims made policies.  Management believes that there are no
claims that may result in a loss in excess of amounts covered by its existing
insurance.

                                                                               8

3. Summary of Significant Accounting Policies (continued)

Goodwill

The cost of the long-term affiliation agreements, which represents the
affiliation consideration over the fair value of identifiable assets acquired,
has been reflected as goodwill and is being amortized over 40 years, the life of
the long-term affiliation agreements.

Impairment of Long-Lived Assets

On January 1, 1996, the Company adopted Statement of Financial Accounting
Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed Of."  Under SFAS 121, the carrying
value of long-lived assets are reviewed if the facts and circumstances suggest
they may be impaired. If this review indicates that the affected assets may not
be recoverable, as determined based upon a projection of undiscounted operating
cash flows, the carrying value of the affected assets would be reduced to fair
value.

Capital Leases

Assets and liabilities relating to capital leases are recorded at the present
value of the future minimum rental payments using interest rates appropriate at
the inception of the lease.  Capital lease amortization is provided on a
straight-line basis over the initial term of the lease and is included with
depreciation expense.

Deferred Affiliation and Equity Offering Costs

Deferred affiliation costs consist of amounts paid in connection with proposed
affiliations with physician practices and related negotiations to provide
management services to such practices.  Costs are capitalized in connection with
affiliations that are considered probable and included in the consideration for
the practices upon consummation of affiliation and management agreements.
Affiliation costs deferred at December 31, 1995 and 1996 amounted to
approximately $315,000 and $113,000, respectively. If a proposed  affiliation is
no longer considered to be probable, the related deferred affiliation costs are
written off.

Costs incurred in connection with the Company's equity offerings are deferred
until the offering is consummated, at which time they are netted against the
proceeds of the equity

                                                                               9

offering to which they pertain.  Equity offering  costs deferred at December 31,
1995 and December 31, 1996 amounted to approximately $457,000 and $25,000,
respectively.

Stock Compensation Arrangements

The Company accounts for its stock compensation arrangements under the
provisions of APB Opinion No. 25, "Accounting for Stock Issued to Employees",
and intends to continue to do so.

The Company has adopted disclosure-only provisions of Statement of Financial
Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation".
These provisions require the Company to disclose pro forma net income and
earnings per share amounts as if compensation expense related to grants of stock
options were recognized based on new fair value accounting rules.

Fair Value of Financial Instruments

The Company's financial instruments consist of accounts receivable, accounts
payable, accrued expenses and other liabilities.  The Company believes that the
carrying value of its financial instruments approximate fair value.

Net Loss Per Common Share

Net loss per share of common stock is computed by dividing the net loss
available to common stock by the weighted-average number of shares of common and
common equivalent shares outstanding during each period presented.  The net loss
available to common stock reflects the accretion of common stock subject to put
to fair value at December 31, 1996 (see Note 10).  The effect of options and
warrants is not considered as it would be antidilutive.  Fully diluted loss per
share is not presented because the effect would be antidilutive.

Risks and Uncertainties

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.

                                                                              10

4. Affiliations

Springfield

Effective August 30, 1996, the Company entered into affiliation arrangements
with 7 physician practices (32 physicians) located in Western Massachusetts (the
Springfield Affiliation).  In connection with this transaction, through mergers
and asset purchases, the assets and liabilities of the physician practices were
transferred to a newly formed professional corporation affiliated with the
Company, Medical Care Partners, P.C. (MCP) and the physicians became employees
of MCP.  The aggregate total consideration paid to the physicians for the
mergers and asset purchases was approximately $9.7 million, of which  $3.2
million was paid in cash and $6.5 million was paid by the issuance of 2,592,245
shares of common stock.  Up to an additional $2.15 million, payable in common
stock, may be paid in the future to certain of the physicians if revenue goals
are met. Such consideration, if and when paid, would be reflected as an expense
in the statement of operations.  In addition, 29 physicians received 2,500
options to purchase common stock at an exercise price of $2.50 per share.

Baltimore

Effective December 11, 1996, the Company entered into affiliation arrangements
with 15 physician practices (59 physicians) located in the Baltimore/Annapolis,
Maryland area  (the Flagship Affiliation).  In connection with this transaction,
through mergers and sales, the assets and liabilities of the physician practices
were transferred to a newly formed professional corporation affiliated with the
Company, Flagship Health, P.A. (Flagship) and the physicians became employees of
Flagship.  The aggregate consideration paid to the physicians at the
consummation of the mergers and asset purchases was approximately $19.8 million,
of which $2.7 million was paid in cash and $17.1 million was paid by the
issuance of 6,842,675 shares of common stock.  Final total consideration is
subject to working capital adjustments within 120 days after closing.  

The Springfield affiliation and the Flagship affiliation have been accounted for
by the purchase method of accounting and accordingly, the purchase price has
been allocated to the tangible assets acquired and liabilities assumed based on
the estimated fair value at affiliation date.

                                                                              11

Company's Class A Common Stock.

7. Leases

The Company maintains operating leases for property and certain office equipment
at its corporate headquarters and a subsidiary site.  The property leases
contain renewal options and escalation clauses and require the Company to pay
certain utilities and taxes over established base amounts.  In addition, the
Company is obligated under operating lease agreements acquired in connection
with the Springfield and Flagship affiliations (see Note 4).

Operating lease expense amounted to $14,679 and $535,479 for the period from
inception to December 31, 1995 and for the year ended December 31, 1996,
respectively.

                                                                              13

8. Letter of Credit

At December 31, 1996, the Company had a letter of credit outstanding in the
amount of $85,000 securing the Company's payment for office improvements at a
subsidiary site.

9. Transactions with Related Parties

The amounts due from related parties at December 31, 1996 represent working
capital and other adjustments in connection with the affiliations (see Note 4).
Because of the nature of the Company's arrangements with the affiliated
physician groups, substantially all transactions included in net patient service
revenues and amounts retained by physician groups in the accompanying financial
statements are viewed as related-party transactions.

9.  Transactions with Related Parties (continued)

During the year ended December 31, 1996, the Company entered into affiliation
transactions with three of its directors who are physicians.  The physicians
received 498,602 shares of Class A common stock, 2,500 options to acquire Class
A common stock, with an exercise price of $2.50 per share and cash in the amount
of $315,000 as consideration for the affiliations.  These transactions were
entered into on commercially reasonable terms, substantially similar to the
terms of its affiliation transactions with other affiliated physicians (see Note
4), and the consideration paid in connection with such affiliations was based on
the fair market value of the medical practice assets or services acquired.

At December 31, 1996, the Company had a promissory note with a face value of
$200,000 with a director of the Company.  The note bears interest at prime plus
2%.  This note, along with accrued interest, was paid by the Company on 
February 4, 1997.

10.  Stockholders' Equity

Common Stock
- ------------

During the period from March 20, 1995 (inception) to December 31, 1995, the
Company issued 7,706,250 shares of $.01 par value common stock to its founders
in exchange for cash of $15,188 and notes of $61,875.  During the year ended
December 31, 1996, 1,012,500 shares of common stock were reacquired by the
Company at a cost of $10,125 in the form of cancellation of a like amount of a
note due from the shareholder.  These shares are subject to certain restrictions
which lapse in August 1998.

Effective August 30, 1996, the Company recapitalized.  All shares of then-
existing common stock were canceled (Old Common Stock) and three new classes of
common stock (Class A, Class B-1 and Class B-2) were authorized.  Holders of
Class A, Class B-1 and Class B-2 common shares are entitled to elect two, one
and one members of the Company's Board of Directors, respectively.  The
remaining seven directors are elected collectively by the holders of Class A,
Class B-1 and Class B-2 common shares, with each share having a single vote.  



                                                                           15

10.  Stockholders' Equity (continued)

Class A common shares were distributed to holders of Old Common Stock on a one-
for-one basis.

On August 30, 1996, 402,301 of Class A common shares were issued in connection
with the conversion of a bridge loan.  The bridge loan, in the amount of $1.0
million, (1) was outstanding during July and August 1996;  (2) bore interest at
10.25% and (3) was convertible into Class A common shares at a conversion rate
of $2.50 per share.  Warrants to purchase 201,150 shares of common stock at
$5.00 per share were issued in connection with the bridge loan.

During June 1995, the Company issued 1,666,151 shares of Series A Convertible
Preferred Stock (Preferred Stock), par value $.01, which effective August 30,
1996, was converted to Class A common stock on a one-for-one basis. Warrants to
purchase 416,538 shares of Common Stock at $2.40 per share were issued upon the
closing of the sale of the Preferred Stock. Warrants to purchase an additional
416,538 shares of common stock were required to be issued to the holders of the
Preferred Stock in the event that the Company did not complete an initial public
offering on or before June 30, 1996.  Accordingly, on August 30, 1996, the
Company  issued an additional 416,538 warrants at $2.40 per share. A total value
of $300,000 were assigned to these warrants.

As discussed in Note 6, 625,000 shares of Class A common stock were issued in
connection with the conversion of a promissory note.

As discussed in Note 4, 2,592,245 Class A common shares were issued in
connection with the Springfield Affiliation, and 6,842,675 Class A common shares
were issued in connection with the Baltimore Affiliation.

In connection with the Springfield Affiliation described in Note 4, on 
August 30, 1996, the Company issued 1,587,863 Class B-1 common shares, 1,012,137
Class B-2 common shares and warrants to purchase 3,750,500 shares of Class B
common stock at $2.50 per share to the Institutional Investors in exchange for
cash proceeds of $6.5 million, which after issuance costs of approximately $1.4
million, netted to approximately $5.1 million. In connection with the Baltimore
Affiliation described in Note 4, on December 11, 1996, the Company issued
855,003 Class B-1 common shares, 544,997 Class B-2 common shares and warrants to
purchase 1,799,000 shares of Class B common stock at $2.50 per share to the
Institutional Investors in exchange for cash proceeds of $3.5 million, which
after issuance costs of approximately $640,000, netted to approximately $2.9
million.




                                                                            16

10.  Stockholders' Equity (continued)

Subject to certain conditions, the Institutional Investors are required to
purchase up to 8,000,000 additional shares of Class B common stock, together
with warrants to purchase up to 7,450,500 shares of Class B common stock, for
aggregate consideration of $20,000,000.  These shares may be sold no later than
December 31, 1999.  The number of shares of common stock issuable upon exercise
of the warrants is subject to adjustment based on the Company's future financial
performance.

During December 1996, the Company issued 142,000 shares of Class A common stock
at $2.50 per share to shareholders for cash.

Puts and Calls
- --------------

Of the Company's outstanding common stock, 12,740,589 shares are subject to a 
put option which provides for the put of the shares back to the Company at fair 
value upon the death of the holder.  In addition, 1,072,285 of such shares are 
also subject to a fair value put option back to the Company at the later of the 
shareholder's retirement from the Company or 18 months after the date
(December 11, 1996) of the shareholders' agreement.  Consequently, these 
12,740,589 shares have been recorded at fair value outside of permanent equity 
in the accompanying balance sheet.

The Company's shareholder agreements also provide that in connection with 
10,053,670 shares of common stock, the Company has the right to purchase such 
shares for fair value if the shareholder's termination from the Company is 
without cause or is by resignation, and for the lower of cost or fair value if 
termination is with cause.

All of the above put and call provisions expire on the date of a Qualified
Public Offering (QPO), defined as a public offering of the Company's common
stock with proceeds to the Company of at least $50 million.

Because the Company's shares are subject to a number of restrictions in the 
shareholders' agreements and will not trade until the occurrence of a QPO, the 
Company believes it is a nonpublic entity for compensation accounting purposes 
and, accordingly, has not recorded any compensation expense for these puts and 
calls.  As noted above, at the date of the QPO, the put and call provisions of 
the shareholder agreements will expire.


Warrants
- --------

In May 1995, the Company issued a stock purchase warrant for consideration of
$90,000, which provided the holder the right to purchase 100,000 shares of
common stock at $20.00 per share.  The warrant expired unexercised on 
December 31, 1995.

In September 1996, the Company issued a stock purchase warrant for consideration
of $115,000, which provided the holder the right to purchase 50,000 shares of
Class A common stock at $3.00 per share.

At December 31, 1996, warrants to purchase 6,653,726 shares of Class A and Class
B common stock  were outstanding as follows:

Net Loss per Common Share
- -------------------------

Net loss per common share disclosed in the statement of operations is calculated
using the methodology discussed in Note 3.  In February 1997, the Financial
Accounting Standards Board (FASB) issued Statement of Financial Accounting
Standards (SFAS) No. 128 "Earnings Per Share," which is required to change the
method currently used to compute earnings per share and to restate all prior
periods.  Under the new requirements for calculating primary earnings per share,
the dilutive effect of stock options will be excluded.  The impact of SFAS 128
on the calculation of net loss per common share for the first quarter ended
March 31, 1997 and March 31, 1996 is not expected to be material.

Supplemental net loss per common share assumes the conversion of 1,666,151
shares of the convertible preferred stock to common stock on a one for one
basis, the conversion of the convertible promissory note payable (see Note 6)
into 625,000 shares of common stock and the conversion of the convertible bridge
loan into 402,301 shares of common stock, all as of January 1, 1996.  The
supplemental net loss per common share for the year ended December 31, 1996 is
as follows:

11.  Employee Compensation Plans

Equity Incentive Plan
- ---------------------

The Company's 1995 Equity Incentive Plan provides the opportunity for employees,
consultants, officers and directors to be granted options to purchase, receive
awards or make direct purchases of up to 1,875,000 shares of the Company's
common stock.  Options granted under the Plan may be "Incentive Stock Options"
or "Nonqualified Options" under the applicable provisions of the Internal
Revenue Code.



                                                                           18

                   Notes to Financial Statements (continued)



11.  Employee Compensation Plans (continued)

Incentive Stock Options are granted at the fair market value of the Company's
common stock at the date of the grant as determined by the Board of Directors.
Incentive Stock Options granted to employees who own more than 10% of the voting
power of all classes of stock will be granted at 110% of the fair market value
of the Company's common stock at the date of the grant.  Nonqualified options
may be granted at amounts up to the fair market value of the Company's common
stock on the date of the grant, as determined by the Board of Directors.

Although FAS 123 requires the presentation of pro forma information to reflect
the fair value method of accounting for employee stock option grants, such
information has not been presented because the pro forma effects are not
material.  The fair value for these options was estimated at the date of grant
using the "minimum value method" prescribed by FAS 123.  The following weighted-
average assumptions were used to determine the fair value for 1995 and 1996,
respectively: a risk-free interest rate of 6.0% and 6.2%, an expected dividend
yield of 0% each year, and a weighted-average expected life of the options of
six years.

A summary of the Company's stock option activity and related information is as

No options were exercised during the period from March 20, 1995 (inception) to
December 31, 1996.  All options granted vest equally over a range of three to
four years.

Profit Sharing Plan
- -------------------

The Board of Directors of the Company approved the adoption of a qualified
401(k) profit sharing plan (the Plan) for all employees meeting certain
eligibility requirements.  Under the Plan, the participants may make
contributions to the Plan of up to 15% of their compensation, up to the Internal
Revenue Service limitation.  Effective December 1, 1996, the Company may make
discretionary contributions to the Plan as  determined by the Board of
Directors.  Contributions for the year ended December 31, 1996 were
approximately $86,000.

Money Purchase Pension Plan
- ---------------------------

The Board of Directors of the Company approved the adoption of a qualified money
purchase pension plan for the employees of MCP.  Effective on August 30, 1996
the Company may provide a contribution on wages up to the Social Security
limitation and up to 9.27% on wages in excess of the Social Security limitation.
The Company contributed approximately $187,000 to the money purchase pension
plan in 1996.

12.  Income Taxes

The Company provides for income taxes under the liability method.  Deferred
income taxes arise principally from temporary differences related to capitalized
start-up costs, depreciation, net operating losses, certain accruals, and a
change from the cash to accrual method of accounting for tax purposes.  The
components of the Company's deferred income taxes are as follows:



                                                                           20

For financial reporting purposes, a valuation allowance of $707,000 and
$2,109,984 at December 31, 1995 and 1996, respectively, has been recognized to
offset deferred tax assets since uncertainty exists with respect to future
realization of deferred tax assets.

12.  Income Taxes (continued)

At December 31, 1996, the Company had net operating loss carryforwards for
federal income tax purposes of approximately $4,460,000 which expire through the
year 2011.  The utilization of net operating losses may be subject to limitation
under the change in stock ownership rules of the Internal Revenue Code.  For
financial reporting purposes, a valuation allowance of approximately $2,109,984
has been recognized to offset the deferred tax assets, including these
carryforwards, since uncertainty exist with respect to future realization of
such carryforwards.

13.  Subsequent Events

In January and February 1997, the Company entered into affiliation arrangements
with 6 physicians located in the Springfield, Massachusetts area (the
Springfield II Affiliation).  Through mergers and asset purchases, the
Springfield II practices were transferred to MCP and the physicians became
employees of MCP.  The aggregate total consideration paid to the physicians or
their practices in connection with the Springfield II Affiliation was
approximately $2.3 million, payable in a combination of cash and common stock.

In January 1997, the Company entered into a $3.5 million line of credit
agreement with a bank.  The line carries an interest rate of prime plus 1.5%.

In February 1997, the Company issued 472,000 shares of Class A common stock for
$1,180,000 to shareholders and friends of the Company.

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.

We have audited the accompanying consolidated balance sheets of Springfield
Medical Associates, Inc. (the Company) as of December 31, 1994 and 1995, and
August 30, 1996 and the related consolidated statements of operations,
stockholders' equity, and cash flows for each of the three years ended December
31, 1995 and the period January 1, 1996 through August 30, 1996.  These
financial statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
Springfield Medical Associates, Inc. at December 31, 1994, 1995, and August 30,
1996 and the consolidated results of its operations and its cash flows for each
of the three years ended December 31, 1995 and the period January 1, 1996
through August 30, 1996, in conformity with generally accepted accounting
principles.

                   Notes to Consolidated Financial Statements

                               December 31, 1995

1.  Summary of Significant Accounting Policies

Description of Business

Springfield Medical Associates, Inc. (the Company) is a taxable entity organized
under the laws of Massachusetts.  The Company offers a variety of medical
services including cardiology, cancer treatment and primary care in Western
Massachusetts.

Principles of Consolidation

The consolidated financial statements of the Company include the accounts of
Springfield Medical Associates and its wholly-owned subsidiaries.  All
intercompany transactions have been eliminated in consolidation.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred, while costs of betterments and renewals are capitalized.

Income Taxes

Deferred income taxes are provided for temporary differences between the
carrying amounts of assets and liabilities for financial reporting purposes and
the amounts used for income tax purposes.

Professional Liability Insurance

The Company has obtained professional liability coverage through commercial
insurance carriers on the occurrence basis.  Management believes that there are

1.  Summary of Significant Accounting Policies (continued)

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  The Company has negotiated
numerous agreements with managed care organizations to provide physician
services based on fee schedules.  No individual managed care contract is
material to the Company.

Risks and Uncertainties

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.

Unaudited Consolidated Financial Statements

The unaudited consolidated financial statements have been prepared by management
in accordance with generally accepted accounting principles.  In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.  Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

                                                                           7

7.  Affiliation

On August 30, 1996, the Company consummated a long-term affiliation arrangement
with Physicians Quality, Inc. (PQC).  Under this arrangement, the physicians
transferred their practices to, and became employees of, a newly formed
professional corporation that is affiliated with PQC.  The aggregate
consideration paid to the physicians for the asset purchases and affiliations
was in a combination of cash and PQC common stock.

The results of operations for the period January 1, 1996 through August 30, 1996
do not reflect an annual physicians bonus accrual which the Company's physicians
elected not to receive prior to the affiliation arrangement with PQC.

                                                                          13

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.

We have audited the accompanying balance sheet of Alphonse F. Calvanese, M.D.,
P.C. (the Practice) as of September 30, 1995, and the related statements of
operations, stockholder's equity, and cash flows for the year then ended.  These
financial statements are the responsibility of management.  Our responsibility
is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Alphonse F. Calvanese, M.D.,
P.C. at September 30, 1995, and the results of operations and cash flows for the
year then ended in conformity with generally accepted accounting principles.

1.  Summary of Significant Accounting Policies

Description of Business

The medical practice of Alphonse F. Calvanese, M.D. (the Practice) is organized
under the laws of Massachusetts.  The practice offers a variety of primary care
medical services in western Massachusetts.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred, while costs of betterments and renewals are capitalized.

Income Taxes

Deferred income taxes are provided for temporary differences between the
carrying amounts of assets and liabilities for financial reporting purposes and
the amounts used for income tax purposes.

Professional Liability Insurance

The practice has obtained professional liability coverage through commercial
insurance carriers on the claims-made basis.  Management believes that there are
no claims that may result in a loss in excess of amounts covered by its existing
insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  The Practice has negotiated
numerous agreements with managed care organizations to provide physician
services based on fee schedules.  No individual managed care contract is
material to the Practice.

                                                                               6

                 Notes to the Financial Statements (continued)



1.  Summary of Significant Accounting Policies (continued)

Risks and Uncertainties

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.

Unaudited Financial Statements

The unaudited financial statements have been prepared by management in
accordance with generally accepted accounting principles.  In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.  Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

2.  Property and Equipment

Property and equipment consisted of the following:

4.  Income Taxes

Deferred income taxes reflect the net effects of temporary differences between
the carrying amounts of assets and liabilities for financial reporting purposes
and the amounts used for income tax purposes.  The Company is a cash-basis
taxpayer.  Significant components of the Company's deferred tax liabilities and
assets were as follows:

5.  Affiliation

On August 31, 1996, the Practice consummated a long-term affiliation arrangement
with Physicians Quality Care, Inc. (PQC).  Under this arrangement, the
physicians transferred their practices to, and became employees of, a newly
formed professional corporation that is affiliated with PQC.  The aggregate
consideration paid to the physicians for the assets purchased and affiliations
was in a combination of cash and PQC common stock.

                         Report of Independent Auditors


The Board of Directors
Cardiology and Internal Medicine Associates, Inc.

We have audited the accompanying balance sheets of Cardiology and Internal
Medicine Associates, Inc. (the Group) as of December 31, 1995 and 1994, and the
related statements of operations, stockholder's equity, and cash flows for the
years then ended.  These financial statements are the responsibility of the
Group'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 Cardiology and Internal
Medicine Associates, Inc. at December 31, 1995 and 1994, and the results of its
operations and its cash flows for each of the years then ended, in conformity
with generally accepted accounting principles.

1.  Summary of Significant Accounting Policies

Description of Business

Cardiology and Internal Medicine Associates, Inc. (CIMA) is a taxable entity
organized under the laws of Massachusetts.  CIMA offers a variety of medical
services, including cardiology and primary care in Western Massachusetts.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred, while costs of betterments and renewals are capitalized.

Income Taxes

CIMA is taxable under the provisions of the Internal Revenue Code. Deferred
income taxes are provided for temporary differences between the carrying amounts
of assets and liabilities for financial reporting purposes and the amounts used
for income tax purposes.

Professional Liability Insurance

CIMA has obtained professional liability coverage through commercial insurance
carriers on an occurrence basis.  Management believes that there are no claims
that may result in a loss in excess of amounts covered by its existing
insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  CIMA has negotiated several
agreements with managed care organizations to provide physician services based
on fee schedules.  No individual managed care contract is material to CIMA.

                                                                               6

1.  Summary of Significant Accounting Policies (continued)

Risks and Uncertainties

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.

Unaudited Financial Statements

The unaudited financial statements as of September 30, 1996 and for the nine
months ended September 30, 1995 and 1996 have been prepared by management in
accordance with generally accepted accounting principles.  In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.  Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

2.  Property and Equipment

Property and equipment consisted of the following:

3.  Line of Credit

CIMA has negotiated a line of credit with a local bank at an interest rate of
9.72%.  This line of credit is secured by all of the practice's assets.  At
December 31, 1994 and 1995 the outstanding balance on the line of credit was
$13,000 and $6,960, respectively.  The available credit under this line was
$5,000 and $11,040 at December 31, 1994 and 1995.

                                                                               7

5.  Income Taxes (continued)

For financial reporting purposes, a valuation allowance of $16,107 and $14,669
at December 31, 1994 and 1995, respectively, has been recognized to offset
certain deferred tax assets since uncertainty exists with respect to future
realization of these tax assets.

Significant components of the provision (benefit) for income taxes attributable
to continuing operations are as follows:

6.  Affiliation

On August 30, 1996, CIMA consummated a long-term affiliation arrangement with
Physicians Quality, Inc. (PQC).  Under this arrangement, the physicians
transferred their practices to, and became employees of, a newly formed
professional corporation that is affiliated with PQC.  The aggregate
consideration paid to the physicians for the asset purchases and affiliations
was in a combination of cash and PQC common stock.

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.

We have audited the accompanying balance sheet of James F. Haines and William J.
Belcastro, Partnership as of December 31, 1995, and the related statements of
operations, partners' capital, and cash flows for the year then ended.  These
financial statements are the responsibility of management.  Our responsibility
is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of James F. Haines and William J.
Belcastro, Partnership at December 31, 1995, and the results of its operations
and its cash flows for the year then ended, in conformity with generally
accepted accounting principles.

1.  Summary of Significant Accounting Policies

Description of Business

The medical practice of James F. Haines and William J. Belcastro, Partnership
(the Partnership) is a general partnership organized under the laws of
Massachusetts.  The practice offers primary care medical services in Western
Massachusetts.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred, while costs of betterments and renewals are capitalized.

Income Taxes

The Partnership is a nontaxable entity under the provisions of the Internal
Revenue Code. The taxable income or loss of the Partnership is allocated to the
partners and then is reported on the partners' individual tax returns.
Therefore, no provision for income taxes is included in these financial
statements.

Professional Liability Insurance

The Partnership has obtained professional liability coverage through commercial
insurance carriers on the claims-made basis.  Management believes that there are
no claims that may result in a loss in excess of amounts covered by its existing
insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  The Partnership has negotiated
agreements with managed care organizations to provide physician services based
on fee schedules.  No individual managed care contract is material to the
Partnership.

                                                                               6

1.  Summary of Significant Accounting Policies (continued)

Risks and Uncertainties

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.

Unaudited Financial Statements

The unaudited financial statements have been prepared by management in
accordance with generally accepted accounting principles.  In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.  Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

2.  Property and Equipment

Property and equipment consisted of the following:

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.

We have audited the accompanying balance sheet of Jay M. Ungar, M.D. as of
December 31, 1995, and the related statements of operations, and cash flows for
the year then ended.  These financial statements are the responsibility of
management.  Our responsibility is to express an opinion on these financial
statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Jay M. Ungar, M.D. at December
31, 1995, and the results of operations and cash flows for the year then ended,
in conformity with generally accepted accounting principles.

1.  Summary of Significant Accounting Policies

Description of Business

The medical practice of Dr. Jay M. Ungar, M.D. (the Practice) is a sole
proprietorship which offers primary care medical services.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred, while costs of betterments and renewals are capitalized.

Professional Liability Insurance

The Practice has obtained professional liability coverage through commercial
insurance carriers on a claims-made basis.  Management believes that there are
no claims that may result in a loss in excess of amounts covered by its existing
insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  The practice has negotiated
numerous agreements with managed care organizations to provide physician
services based on fee schedules.

Risks and Uncertainties

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.


                                                                               5

The unaudited financial statements at August 30, 1996 and for the nine months
ended September 30, 1995 and the period January 1, 1996 through August 30, 1996
have been prepared by management in accordance with generally accepted
accounting principles.  In the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation have been included.  Operating results of the interim periods are
not necessarily indicative of the results that may be expected for a full year.

3.  Affiliation

On August 31, 1996, Jay M. Ungar, M.D. consummated a long-term affiliation
arrangement with Physicians Quality Care, Inc. (PQC).  Under this arrangement,
the physician transferred his practices to, and became an employee of, a newly
formed professional corporation that is affiliated with PQC.  The aggregate
consideration paid to the physician for the asset purchases and affiliations was
in a combination of cash and PQC common stock.

                                                                               6

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.

We have audited the accompanying balance sheets Western Massachusetts Medical
Group, Inc. as of November 30, 1995, and the related statements of operations,
stockholder's equity, and cash flows for the year then ended.  These financial
statements are the responsibility of the Group's management.  Our responsibility
is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Western Massachusetts Medical
Group, Inc. at November 30, 1995, and the results of its operations and its cash
flows for the year then ended in conformity with generally accepted accounting
principles.

1. Summary of Significant Accounting Policies

Description of Business

Western Massachusetts Medical Group, Inc. (the Group) is a taxable entity
organized under the laws of Massachusetts.  The Group offers primary medical
services in Western Massachusetts.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred, while costs of betterments and renewals are capitalized.

Income Taxes

The Group is taxable under the provisions of the Internal Revenue Code. Deferred
income taxes are provided for temporary differences between the carrying amounts
of assets and liabilities for financial reporting purposes and the amounts used
for income tax purposes.

Professional Liability Insurance

The Group has obtained professional liability coverage through commercial
insurance carriers on the occurrence basis.  Management believes that there are
no claims that may result in a loss in excess of amounts covered by its existing
insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  The Group has negotiated numerous
agreements with managed care organizations to provide physician services based
on fee schedules.  No individual managed care contract is material to the Group.

                                                                               6

1.  Summary of Significant Accounting Policies (continued)

Risks and Uncertainties

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.

Unaudited Financial Statements

The unaudited financial statements have been prepared by management in
accordance with generally accepted accounting principles. In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included. Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

2.  Property and Equipment

Property and equipment consisted of the following:

7.  Affiliation

On August 30, 1996, the Western Massachusetts Medical Group, Inc. consummated a
long-term affiliation arrangement with Physicians Quality Care, Inc.  (PQC).
Under this arrangement, the physicians transferred their practices to, and
became employees of, a newly formed professional corporation that is affiliated
with PQC.  The aggregate consideration paid to the physicians for the asset
purchases and affiliations was in a combination of cash and PQC common stock.

                                                                              11

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.

We have audited the accompanying balance sheets of Annapolis Medical
Specialists, LLP (the Partnership) as of December 31, 1994 and 1995 and the
related statements of operations, partners capital, and cash flows each of the
three years in the period ended December 31, 1995.  These financial statements
are the responsibility of 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 Annapolis Medical Specialists,
LLP, at December 31, 1994 and 1995 and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1995, in
conformity with generally accepted accounting principles.

1.  Summary of Significant Accounting Policies

Description of Business

Annapolis Medical Specialists, LLP (the Partnership) is a limited liability
partnership organized under the laws of Maryland.  The Partnership offers a
variety of medical services, including cardiology, hematology/oncology,
infectious disease, pulmonary/critical care and internal medicine, in the
greater Annapolis, Maryland area.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred.  Amortization of assets recorded under capital lease transactions is
included in depreciation expense.

Income Taxes

For tax purposes, Annapolis Medical Specialists, LLP is treated as a partnership
and a pass-through entity.  The taxable income or loss of the practice is
allocated to the partners and reported on the partners' tax returns.  Therefore,
no provision for income taxes is included in these financial statements.

Professional Liability Insurance

The Partnership has obtained professional liability coverage through commercial
insurance carriers on a claims-made basis.  Management believes that there are
no claims that may result in a loss in excess of amounts covered by its existing
insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  The Partnership has negotiated
numerous agreements with managed care organizations to provide physician
services based on fee schedules.  No individual managed care contract is
material to the Partnership.

                                                                               7

1.  Summary of Significant Accounting Policies (continued)

Risks and Uncertainties

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.

Unaudited Financial Statements

The unaudited financial statements as of September 30, 1996 and for the nine
months ended September 30, 1995 and 1996 have been prepared by management in
accordance with generally accepted accounting principles.  In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.  Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

2.  Property and Equipment

Property and equipment consisted of the following:

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.


We have audited the accompanying balance sheet of Drs. Fortier, Libber, Clemmens
& Weimer, P.A. as of December 31, 1995, and the related statements of
operations, shareholders' equity, and cash flows for the year then ended.  These
financial statements are the responsibility of management.  Our responsibility
is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Drs. Fortier, Libber, Clemmens
& Weimer, P.A. at December 31, 1995, and the results of its operations and its
cash flows for the year then ended in conformity with generally accepted
accounting principles.

1.  Summary of Significant Accounting Policies

Description of Business

Drs. Fortier, Libber, Clemmens & Weimer, P.A. (Pediatrics) is a professional
association organized under the laws of Maryland.  Pediatrics offers a variety
of medical services, including pediatrics and primary care, in the greater
Annapolis, Maryland area.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred.  Amortization of assets recorded under capital lease transactions is
included in depreciation expense.

Income Taxes

Pediatrics is taxable under the provisions of the Internal Revenue Code.
Pediatrics files its federal and state income tax return on the cash basis
method of accounting.  Deferred income taxes are provided for temporary
differences between the carrying amount of assets and liabilities for financial
reporting purposes and the amounts used for income tax purposes (see Note 8).

Professional Liability Insurance

Pediatrics has obtained professional liability coverage through commercial
insurance carriers on the claims-made basis.  Management believes that there are
no claims that may result in a loss in excess of amounts covered by its existing
insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  Pediatrics has negotiated numerous
agreements with managed care organizations to provide physician services based
on fee schedules.  No individual managed care contract is material to
Pediatrics.

                                                                               6

1.  Summary of Significant Accounting Policies (continued)

Risks and Uncertainties

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.

Unaudited Financial Statements

The unaudited financial statements as of September 30, 1996 and for the nine
months ended September 30, 1995 and 1996 have been prepared by management in
accordance with generally accepted accounting principles.  In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.  Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

2.  Property and Equipment

Property and equipment consisted of the following at December 31, 1995:

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.


We have audited the accompanying balance sheet of Drs. Goldgeier, Levine &
Friedman, P.A. as of December 31, 1995, and the related statements of
operations, shareholders' equity, and cash flows for the year then ended.  These
financial statements are the responsibility of management.  Our responsibility
is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Drs. Goldgeier, Levine &
Friedman, P.A. at December 31, 1995, and the results of its operations and its
cash flows for the year then ended in conformity with generally accepted
accounting principles.

1.  Summary of Significant Accounting Policies

Description of Business

Drs. Goldgeier, Levine & Friedman, P.A. (the Company) is a professional
association organized under the laws of Maryland.  The Company offers a variety
of medical services including pediatrics and primary care in the greater
Baltimore, Maryland area.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred.  Amortization of assets recorded under capital lease transactions is
included in depreciation expense.

Income Taxes

The Company is taxable under the provisions of the Internal Revenue Code.  The
Company files its federal and state income tax return on the cash basis method
of accounting.  Deferred income taxes are provided for temporary differences
between financial and income tax reporting (see Note 8).

Professional Liability Insurance

The Company has obtained professional liability coverage through commercial
insurance carriers on the claims made basis.  Management believes that there are
no claims that may result in a loss in excess of amounts covered by its existing
insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered. The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency. The Company has negotiated numerous
agreements with managed care organizations to provide physician services based
on fee schedules. No individual managed care contract is material to the
Company.

                                                                               6

1.  Summary of Significant Accounting Policies (continued)

Risks and Uncertainties

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.

Unaudited Financial Statements

The unaudited financial statements as of September 30, 1996 and for the nine
months ended September 30, 1995 and 1996 have been prepared by management in
accordance with generally accepted accounting principles.  In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.  Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

2.  Property and Equipment

Property and equipment consisted of the following at December 31, 1995:

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.

We have audited the accompanying balance sheet of Koeppel, Rosen, Rudikoff,
M.D., P.C., as of December 31, 1995, and the related statement of operations,
stockholders' equity, and cash flows for the year then ended.  These financial
statements are the responsibility of management. Our responsibility is to
express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Koeppel, Rosen, Rudikoff, M.D.,
P.C. at December 31, 1995, and the results of its operations and its cash flows
for the year then ended, in conformity with generally accepted accounting
principles.

1.  Summary of Significant Accounting Policies

Description of Business

The medical practice of Koeppel, Rosen, Rudikoff, M.D., P.C, (the Company), is a
professional corporation organized under the laws of Maryland.  The Company
offers a variety of medical services including cardiology, pediatrics, cancer
treatment, gastrointestinal and primary care.


Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred.

Income Taxes

The Company has elected, by consent of its shareholders, to be taxed as an S
Corporation under the provisions of the Internal Revenue Code (the Code).
Pursuant to the Code, S Corporations are taxed as pass-through entities.  The
taxable income or loss of the Company is allocated to the Company's shareholders
and reported on the shareholders' tax returns.  Accordingly, there is no
provision for income taxes included in these financial statements.

Professional Liability Insurance

The Company has obtained professional liability coverage through commercial
insurance carriers on a modified claims made basis, which excludes tail
coverage.  Management believes that there are no claims that may result in a
loss in excess of amounts covered by its existing insurance.

                                                                               6

1.  Summary of Significant Accounting Policies (continued)

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  The Company has negotiated
numerous agreements with managed care organizations to provide physician
services based on fee schedules.  No individual managed care contract is
material to the Company.

Risks and Uncertainties

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.

Unaudited Financial Statements

The unaudited statements of operations for nine months ended September 30, 1996
and for the nine months ended September 30, 1995 have been prepared by
management in accordance with generally accepted accounting principles.  In the
opinion of management, all adjustments (consisting of normal recurring accruals)
considered necessary for a fair presentation have been included.  Operating
results of the interim periods are not necessarily indicative of the results
that may be expected for a full year.

2.  Property and Equipment

Property and equipment consisted of the following:

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.

We have audited the accompanying balance sheet of Drs. Pakula, Davick & Bogue,
P.A. as of December 31, 1995, and the related statements of operations,
stockholders' equity, and cash flows for the year then ended.  These financial
statements are the responsibility of management. Our responsibility is to
express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Drs. Pakula, Davick & Bogue,
P.A. at December 31, 1995, and the results of its operations and its cash flows
for the year then ended, in conformity with generally accepted accounting
principles.

1.  Summary of Significant Accounting Policies

Description of Business

The medical practice of Drs. Pakula, Davick & Bogue, P.A. (the Company) is a 
professional association organized under the laws of Maryland.  The Company 
offers a variety of medical services, including cardiology, pediatrics, cancer 
treatment, gastrointestinal and primary care.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and 
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as 
incurred.

Income Taxes

The Company is taxable under the provisions of the Internal Revenue Code.  The 
Company files its federal and state income tax return on the cash basis of 
accounting.  Deferred income taxes are provided for temporary differences 
between financial and income tax reporting (see Note 5).

Professional Liability Insurance

The Company has obtained professional liability coverage through commercial 
insurance carriers on a claims-made basis.  Management believes that there are 
no claims that may result in a loss in excess of amounts covered by its existing
insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered. The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency. The Company has negotiated numerous
agreements with managed care organizations to provide physician services based
on fee schedules. No individual managed care contract is material to the
Company.


                                                                               6

1. Summary of Significant Accounting Policies (continued)

Risks and Uncertainties

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 these estimates.

Unaudited Financial Statements

Unaudited statements of operations for nine months ended September 30, 1996 and 
for the nine months ended September 30, 1995 have been prepared by management in
accordance with generally accepted accounting principles. In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included. Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

2. Property and Equipment

Property and equipment consisted of the following:

5.  Income Taxes

The Company accounts for income taxes using the liability method required by 
Financial Accounting Standards Board (FASB) Statement No. 109, "Accounting for 
Income Taxes."

the carrying amounts of assets and liabilities for financial reporting purposes 
and the amounts used for income tax purposes. Significant components of the 
Company's deferred tax liabilities and assets were as follows:

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.


We have audited the accompanying consolidated balance sheets of Park Medical
Associates, P.A. and Park Medical Labs, Inc. (the Companies) as of December 31,
1995 and 1994, and the related consolidated statements of operations, owners'
equity, and cash flows for each of the three years in the period ended December
31, 1995.  These financial statements are the responsibility of the Companies'
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 consolidated financial position of Park Medical
Associates, P.A. and Park Medical Labs, Inc. at December 31, 1995 and 1994, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended December 31, 1995, in conformity with
generally accepted accounting principles.

1.  Summary of Significant Accounting Policies

Description of Business

Park Medical Associates, P.A. and Park Medical Labs, Inc. (the Companies) are
taxable entities organized under the laws of Maryland.  The Companies offer a
variety of medical services, including internal medicine, neurology and
obstetrics/gynecology, in the greater Baltimore, Maryland area.

Principles of Consolidation

The accompanying consolidated financial statements reflect the accounts of the
Companies. These Companies are affiliated through, and managed by, common
ownership.  All significant intercompany accounts and transactions are
eliminated upon consolidation.

Cash Equivalents

Cash equivalents consist of cash in banks and an interest-bearing money market
accounts.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred.  Amortization of assets recorded under capital leases is included in
depreciation expense.

Income Taxes

Park Medical Associates, P.A. is taxable under the provisions of the Internal
Revenue Code and files a separate cash-basis federal and state income tax
return, reporting only its own taxable income (loss) for the year.  No provision
for federal income tax is required for Park Medical Laboratories since this
entity, with consent of its shareholders, has elected to be taxed as an S
corporation under the provisions of the Internal Revenue Code. Deferred income
taxes are provided for temporary differences between the carrying amounts of
assets and liabilities for financial reporting purposes and the amounts used for
income tax purposes (see Note 7).

                                                                               6

1.  Summary of Significant Accounting Policies (continued)

Professional Liability Insurance

The Companies have obtained professional liability coverage through commercial
insurance carriers on both the occurrence and claims-made basis.  Management
believes that there are no claims that may result in a loss in excess of amounts
covered by its existing insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  The Companies have negotiated
numerous agreements with managed care organizations to provide physician
services based on fee schedules.  No individual managed care contract is
material to the Companies.

Risks and Uncertainties

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.

Unaudited Financial Statements

The unaudited financial statements as of September 30, 1996 and for the nine
months ended September 30, 1995 and 1996 have been prepared by management in
accordance with generally accepted accounting principles.  In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.  Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

                                                                               7

                         Report of Independent Auditors


The Board of Directors
Physicians Quality Care, Inc.

We have audited the accompanying balance sheets of Drs. Sigler, Roskes, Holden &
Schuberth, P.A. as of December 31, 1994 and 1995, and the related statements of
operations, shareholders' equity, and cash flows for the years then ended.
These financial statements are the responsibility of 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 Drs. Sigler, Roskes, Holden &
Schuberth, P.A. at December 31, 1994 and 1995, and the results of its operations
and its cash flows for the years then ended in conformity with generally
accepted accounting principles.

1.  Summary of Significant Accounting Policies

Description of Business

Drs. Sigler, Roskes, Holden & Schuberth, P.A. (the Company) is a taxable entity
organized under the laws of Maryland.  The Company offers a variety of medical
services, including pediatrics and primary care, in the greater Baltimore,
Maryland area.

Property and Equipment

Property and equipment are stated at cost.  Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets.  Routine maintenance and repairs are charged to expense as
incurred.  Amortization of assets recorded under capital lease transactions is
included in depreciation expense.

Income Taxes

The Company is taxable under the provisions of the Internal Revenue Code.  The
Company files its federal and state income tax return on the cash-basis method
of accounting.  Deferred income taxes are provided for temporary differences
between the carrying amount of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes (see Note 7).

Professional Liability Insurance

The Company has obtained professional liability coverage through commercial
insurance carriers on the claims-made basis.  Management believes that there are
no claims that may result in a loss in excess of amounts covered by its existing
insurance.

Net Patient Service Revenue

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered.  The Medicare and
Medicaid programs pay physician services based on fee schedules which are
determined by the related government agency.  The Company has negotiated
numerous agreements with managed care organizations to provide physician
services based on fee schedules.  No individual managed care contract is
material to the Company.
                              

                                                                           6

1.  Summary of Significant Accounting Policies (continued)

Risks and Uncertainties

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.

Unaudited Financial Statements

The unaudited financial statements as of September 30, 1996 and for the nine
months ended September 30, 1995 and 1996 have been prepared by management in
accordance with generally accepted accounting principles.  In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.  Operating results of the
interim periods are not necessarily indicative of the results that may be
expected for a full year.

2.  Property and Equipment

Property and equipment consisted of the following:

Item 14.  Indemnification of Directors and Officers

     Section 145 of the General Corporation Law of Delaware provides that a
corporation has the power to indemnify a director, officer, employee or agent of
the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceedings to which he or she is or is threatened
to be made a party by reason of such position, if such person shall have acted
in good faith and in a manner he or she reasonably believed to be in or not
opposed to the best interest of the corporation, and, in any criminal
proceedings, if such person had no reasonable cause to believe his or her
conduct was unlawful; provided that, in the case of actions brought by or in the
right of the corporation, no indemnification shall be made with respect to any
matter as to which such person shall have been adjudged to be liable to the
corporation unless and only to the extent that the adjudicating court determines
that such indemnification is proper under the circumstances.

     Article SIXTH of the Registrant's Restated Certificate of Incorporation
provides that a director or officer of the Registrant (a) shall be indemnified
by the Registrant against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement reasonably incurred in connection with any
litigation or other legal proceedings (other than an action by or in the right
of the Registrant) brought against such person by virtue of his or her position
as a director or officer of the Registrant if he or she acted in good faith and
in a manner he or she reasonably believed to be in or not opposed to the best
interests of the Registrant, and, with respect to any criminal action or
proceedings, had no reasonable cause to believe his or her conduct was unlawful
and (b) shall be indemnified by the Registrant against expenses (including
attorneys' fees) and amounts paid in settlement reasonably incurred in
connection with any action by or in the right of the Registrant if such person
acted in a manner he or she reasonably believed to be in or not opposed to the
best interests of the Registrant, except that no indemnification shall be made
with respect to any such matter as to which such director or officer shall have
been adjudged to be liable to the Registrant, unless and only to the extent that
a court determines 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 as the court deems proper. Notwithstanding the
foregoing, to the extent that a director or officer has been successful, on the
merits or otherwise, such person shall be indemnified against all expenses
(including attorneys' fees) reasonably incurred by him in connection therewith.
Expenses incurred in defending a civil or criminal action, suit or proceedings
shall be advanced by the


                                     II-1
<PAGE>
 
Registrant to a director or officer, at his or her request, upon receipt of an
undertaking by the director or officer to repay such amount if it is
ultimately determined that he or she is not entitled to indemnification.

     Indemnification is required to be made unless the Registrant determines (in
the manner provided in the Restated Certificate of Incorporation) that the
applicable standard of conduct required for indemnification has not been met. In
the event of a determination by the Registrant that the director or officer did
not meet the applicable standard of conduct required for indemnification, or if
the Registrant fails to make an indemnification payment within 60 days after
such payment is claimed by such person, such person is permitted to petition a
court to make an independent determination as to whether such person is entitled
to indemnification. As a condition precedent to the right of indemnification,
the director or officer must give the Registrant notice of the action for which
indemnity is sought and the Registrant has the right to participate in such
action or assume the defense thereof.

     Article SIXTH of the Registrant's Restated Certificate of Incorporation
further provides that the indemnification provided therein is not exclusive, and
provides that in the event that the Delaware General Corporation Law is amended
to expand the indemnification permitted to directors or officer, the Registrant
must indemnify those persons to the fullest extent permitted by such law as so
amended.

     The Registrant intends to purchase a general liability insurance policy
which covers certain liabilities of directors and officers of the Registrant
arising out of claims based on acts or omissions in their capacity as directors
or officers.

     Article FIFTH of the Registrant's Restated Certificate of Incorporation
provides that, except to the extent that the General Corporation Law of Delaware
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no directors of the Registrant shall be personally liable to
the Registrant or its stockholders for monetary damages for any breach of
fiduciary duty as a director.

Item 17.  Undertakings

     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 contained in the



                                     II-5
<PAGE>
 
Restated Certificate of Incorporation and Amended and Restated By-Laws of the
Registrant and the laws of the State of Delaware, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

     The undersigned Registrant hereby undertakes:

            (1)     To file, during any period in which offers or sales are
     being made, a post-effective amendment to this Registration Statement:

              (i)   To include any prospectus required by section 10(a)(3) of
                    the Securities Act of 1933;

              (ii)  To reflect in the prospectus any facts or events arising
                    after the effective date of the registration statement (or
                    the most recent post-effective amendment thereof) which,
                    individually or in the aggregate, represent a fundamental
                    change in the information set forth in the registration
                    statement. Notwithstanding the foregoing, any increase or
                    decrease in volume of securities offered (if the total
                    dollar value of securities offered would not exceed that
                    which was registered) and any deviation from the low or high
                    end of the estimated maximum offering range may be reflected
                    in the form of prospectus filed with the Commission pursuant
                    to Rule 424(b) if, in the aggregate, the changes in volume
                    and price represent no more than a 20% change in the maximum
                    aggregate offering price set forth in the "Calculation of
                    Registration Fee" table in the effective registration
                    statement.

              (iii) To include any material information with respect to the plan
                    of distribution not previously disclosed in the registration
                    statement or any material change to such information in the
                    registration statement.

              (2)   That, for the purpose of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered therein, and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

              (3)   To remove from registration by means of a post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the offering

          Directors (the "Number of Directors") shall be eleven. The directors
          shall be divided into classes, elected as follows:

          (a) Class A Directors. The holders of record of outstanding shares of
              Class A Common Stock, voting separately as a single class, shall
              be entitled to elect two directors of the Corporation (such
              directors to be designated and referred to herein as the "Class A
              Directors");

          (b) Class B-1 Directors. The holders of record of outstanding shares
              of Class B-1 Common Stock, voting separately as a single class,
              shall be entitled to elect one director of the Corporation (such
              director to be designated and referred to herein as the "Class B-1
              Director");

          (c) Class B-2 Directors. The holders of record of outstanding shares
              of Class B-2 Common Stock, voting separately as a single class,
              shall be entitled to elect one director of the Corporation (such
              director to be designated and referred to herein as the "Class B-2
              Director," together with the Class B-1 Director, the "Class B
              Directors"); and

          (d) Common Stock Directors. The holders of record of outstanding
              shares of Common Stock, voting together as a single class, shall
              be entitled to elect seven directors of the Corporation (such
              directors to be designated and referred to herein as the "Common
              Stock Directors").

   4.5.1  Except as otherwise provided in this Article Fourth, each Class A
          Director, Class B Director and Common Stock Director shall be entitled
          to one vote on all matters to be voted on by the directors. The
          Directors shall vote together as a single class on all matters to
          which the Board of Directors shall be entitled to vote.

   4.5.2  Any vacancy in the Board of Directors shall be filled only by vote of
          the holders of a majority of the outstanding shares of the class or
          classes of Common Stock which was entitled to elect the director whose
          office is vacant. The Board of Directors shall be deemed to be duly
          constituted notwithstanding one or more vacancies in its membership,
          whether because of the failure of

                                      -11-
<PAGE>
 
                 any class of stockholders to elect the full number of directors
                 of which such class is entitled or otherwise. Any such vacancy
                 shall automatically reduce the Number of Directors pro tanto
                 until such time as the holders of the class of Common Stock
                 which was entitled to elect the director whose office is vacant
                 shall have exercised their right to elect a director to fill
                 such vacancy, whereupon the Number of Directors shall be
                 automatically increased pro tanto.

          4.5.3  No Class A Director, Class B Director or Common Stock Director
                 may be removed without the consent of the holders of such class
                 or classes of Common Stock entitled to elect such director.

          4.5.4  With respect to each Class B Director Action, each of the Class
                 B Directors shall be entitled to five votes.

          4.5.5  Upon the occurrence of any Class B Director Control Event and
                 for so long as such Class B Director Control Event or any other
                 Class B Director Control Event shall continue in effect, each
                 Class B Director shall be entitled to five votes.

     4.6  Stock Splits and Stock Dividends. The Corporation shall not in any
          manner subdivide or increase (by stock split, stock dividend or other
          similar manner) reclassify or combine in any manner the outstanding
          shares of Class A Common Stock unless a proportional adjustment is
          made to the Class B Conversion Factor. The Corporation shall not in
          any manner subdivide or increase (whether by stock split, stock
          dividend or other similar manner), reclassify or combine in any manner
          the outstanding shares of the Class B Common Stock unless a
          proportional adjustment is made to the Class A Common Stock.

     4.7  Mandatory Conversion of Class B Common Stock. Upon the earlier to
          occur of (i) a Qualified Public Offering, and (ii) the date on which
          the number of outstanding shares of Class B Common Stock equals the
          lesser of (a) 30% of the number of shares of Class B Common Stock
          issued and outstanding and (b)(1) 1,200,000, in the event the number
          of shares of Class B Common Stock issued equals or exceeds 4,000,000
          and is less than 8,000,000, (2) 1,600,000, in the event the number of
          shares of Class B Common Stock issued and equals or exceeds 8,000,000
          and is less than 12,000,000 and (3) 2,000,000 in the event the number
          of shares of Class B Common Stock issued equals or exceeds 12,000,000.
          Each outstanding share of Class B Common Stock shall automatically
          convert into the number of shares of Class A Common Stock determined
          by application of the Class B Conversion Factor. Fractional shares
          shall be converted

                                      -12-
<PAGE>
 
          into equivalent fractional shares of Class A Common Stock (or, at the
          discretion of the Board of Directors, eliminated in return for payment
          therefor in cash at the fair market value thereof, as determined in
          good faith by the Board of Directors). From and after such conversion,
          (a) such shares of Class B Common Stock shall be retired and shall not
          be reissued, (b) notwithstanding anything to the contrary in this
          Article Fourth, the holders of the Class A Common Stock shall be
          entitled to elect the entire Number of Directors consisting of the
          full Board of Directors and each such director shall have one vote on
          all matters to be voted on by the directors, (c) the Restated
          Certificate of Incorporation shall automatically be amended to
          eliminate Sections 4.2.6, 4.2.7, 4.2.23, 4.5.4, and 4.5.5 and (d) upon
          the filing of a certificate in accordance with Section 243 of the
          General Corporation Law of the State of Delaware, the authorized
          shares of Class B Common Stock shall be eliminated.

     4.8  Optional Conversion of Class B Common Stock. At the option of any
          holder of the shares of Class B Common Stock, exercisable at any time,
          in whole or in part, each outstanding share of Class B Common Stock
          held by such holder shall convert into the number of shares of Class A
          Common Stock as determined by application of the Class B Conversion
          Factor. From and after such optional conversion, such shares of Class
          B Common Stock shall be retired and shall not be reissued, and upon
          the conversion of all outstanding shares of Class B Common Stock and
          upon the filing of a certificate in accordance with Section 243 of the
          General Corporation Law of the State of Delaware, the authorized
          shares of Class B Common Stock shall be eliminated.

     4.9  Effect of Conversion. Upon conversion of any share of Class B Common
          Stock, the holder shall surrender the certificate evidencing such
          shares to the Corporation at its principal place of business. Promptly
          after receipt of such certificate, the Corporation shall issue and
          send to such holder a new certificate, registered in the name of such
          holder, evidencing the number of shares of Class A Common Stock into
          which such share has been converted. From and after the time of
          conversion of any share of Class B Common Stock, the rights of the
          holder thereof as such shall cease; the certificate formerly
          evidencing such share shall, until surrendered and reissued as
          provided above, evidence the applicable number of shares of Class B
          Common Stock; and such holder shall be deemed to have become the
          holder of record of the same number of shares of the Class A Common
          Stock.

     4.10 Replacement.  Upon receipt of an affidavit of the registered owner of
          one or more shares of any class of Common Stock (or such other
          evidence as may be reasonably satisfactory to the Corporation) with
          respect to the

                                      -13-
<PAGE>
 
          ownership and the loss, theft, destruction or mutilation of any
          certificate evidencing such shares of Common Stock, and in the case of
          any such loss, theft or destruction, upon receipt of indemnity
          reasonably satisfactory to the Corporation (it being understood that
          if the holder is a Bain Capital Investor, or any other holder of
          shares of Common Stock of the Corporation which is an entity regularly
          engaged in the business of investing in companies and meets such
          requirements of creditworthiness as may reasonably be imposed by the
          Corporation in connection with the provisions of this paragraph, its
          own agreement will be satisfactory), or, in the case of any such
          mutilation upon surrender of such certificate, the Corporation shall
          execute and deliver in lieu of such certificate a new certificate of
          like kind representing the number of shares of such class represented
          by such lost, stolen, destroyed or mutilated certificate and dated the
          date of such lost, stolen, destroyed or mutilated certificate.

     4.11 Amendment; Waiver. No amendment or waiver of any provision of this
          Article Fourth shall be effective without the prior written consent of
          the holders of a majority of the then outstanding shares of the Class
          B Common Stock voting as a single class and no amendment or waiver of
          any provision of this Article Fourth which adversely affects the
          holders of Class A Common Stock or increased the rights of the Class B
          Common Stock shall be effective without the prior written consent of
          the holders of a majority of the then outstanding shares of the Class
          A Common Stock voting as a single class; provided, however, that as
          stipulated in Section 242(b)(2) of the Delaware General Corporation
          Law no amendment to any class of Common Stock that alters or changes
          the powers, preferences or special rights of such class of Common
          Stock so as to affect them adversely shall be effective without the
          prior consent of the holders of a majority of the then outstanding
          shares of such class of Common Stock.

     FIFTH: Except to the extent that the General Corporation Law of Delaware
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, notwithstanding any provision of law imposing such
liability.  No amendment to or repeal of this provision shall apply to or have
any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions occurring prior to such
amendment.

     SIXTH:

     6.1  Actions, Suits and Proceedings Other than by or in the Right of the
          -------------------------------------------------------------------
          Corporation. The Corporation shall indemnify each 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 such person is
          or was, or is or was serving, or has agreed to serve, at the request
          of the Corporation, as a director, officer of trustee of, or in a
          similar capacity with, another corporation, partnership, joint
          venture, trust or other enterprise (including any employee benefit
          plan) (all such persons being referred to hereafter as an
          "Indemnitee"), or by reason of any action alleged to have been taken
          or omitted in such capacity, against all expenses (including
          attorneys' fees), judgments, fines and amounts paid in settlement
          actually and reasonably incurred by such person or on such person's
          behalf in connection with such action, suit or proceeding and any
          appeal therefrom, if such person acted in good faith and in a manner
          such person 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 such person's
          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 such person reasonably believed to be in, or not opposed to, the
          best interest of the Corporation, and, with respect to any criminal
          action or proceeding, had reasonable cause to believe that such
          person's conduct was unlawful. Notwithstanding anything to the
          contrary in this Article, except as set forth in Section 6.7 below,
          the Corporation shall not indemnify an Indemnitee seeking
          indemnification in connection with a proceeding (or part thereof)
          initiated by the Indemnitee unless the initiation thereof was approved
          by the Board of Directors of the Corporation. Notwithstanding anything
          to the contrary in this Article, the Corporation shall not indemnify
          an Indemnitee to the extent such Indemnitee is reimbursed from the
          proceeds of insurance, and in the event the Corporation makes any
          indemnification payments to an Indemnitee and such Indemnitee is
          subsequently reimbursed from the proceeds of insurance, such
          Indemnitee shall promptly refund such indemnification payments to the
          Corporation to the extent of such insurance reimbursement.

     6.2  Actions or Suits by or in the Right of the Corporation.  The
          ------------------------------------------------------      
          Corporation shall indemnify any Indemnitee who was or is a party or is
          threatened

                                      -15-
<PAGE>
 
          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 such person is or was, or has
          agreed to become, a director or officer of the Corporation, or is or
          was serving, or has agreed to serve, at the request of the
          Corporation, as a director, officer or trustee of, or in a similar
          capacity with, another corporation, partnership, joint venture, trust
          or other enterprise (including any employee benefit plan), or by
          reason of any action alleged to have been taken or omitted in such
          capacity, against all expenses (including attorneys' fees) and, to the
          extent permitted by law, amounts paid in settlement actually and
          reasonably incurred by such person or on such person's behalf in
          connection with such action, suit or proceeding and any appeal
          therefrom, if such person acted in good faith and in a manner
          reasonably believed to be in, or not opposed to, the best interests of
          the Corporation, 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 of Delaware shall determine upon
          application that, despite the adjudication of such liability but in
          view of all the circumstances of the case, such person is fairly and
          reasonably entitled to indemnify for such expenses (including
          attorneys' fees) which the Court of Chancery of Delaware shall deem
          proper.

     6.3  Indemnification for Expenses of Successful Party.  Notwithstanding the
          ------------------------------------------------                      
          other provisions of this Article, to the extent than an Indemnitee has
          been successful, on the merits or otherwise, in defense of any action,
          suit or proceeding referred to in Sections 6.1 and 6.2 of this
          Article, or in defense of any claim, issue or matter therein, or on
          appeal from any such action, suit or proceeding, the Indemnitee shall
          be indemnified against all expenses (including attorneys' fees)
          actually and reasonably incurred by the Indemnitee or on the
          Indemnitee's behalf in connection therewith. Without limiting the
          foregoing, if any action, sit or proceeding is disposed of, on the
          merits or otherwise (including a disposition without prejudice),
          without (i) the disposition being adverse to the Indemnitee, (ii) an
          adjudication that the Indemnitee was liable to the Corporation, (iii)
          a plea of guilty or nolo contendere by the Indemnitee, (iv) an
          adjudication that the Indemnitee did not act in good faith and in a
          manner the Indemnitee reasonably believed to be in or not opposed to
          the best interests of the Corporation, and (v) with respect to any
          criminal proceeding, an adjudication that the Indemnitee had
          reasonable cause to believe the Indemnitee's conduct was unlawful, the
          Indemnitee shall be considered for the purposes hereof to have been
          wholly successful with respect thereto.

     6.4  Notification and Defense of Claim.  As a condition precedent to the
          ---------------------------------                                  
          right to be indemnified, the Indemnitee must notify the Corporation in
          writing as soon as practicable of any action, suit, proceeding or
          investigation involving the Indemnitee for which indemnity will or
          could be sought. With respect to any action, suit, proceeding or
          investigation of which the Corporations is so notified, the
          Corporation will be entitled to participate therein at is own expense
          and/or to assume the defense thereof at its own expense, with legal
          counsel reasonably acceptable to the Indemnitee. After notice from the
          Corporation to the Indemnitee of its election so to assume such
          defense, the Corporation shall not be liable to the Indemnitee for any
          legal or other expenses subsequently incurred by the Indemnitee in
          connection with such claim, other than as provided below in this
          Section 6.4. The Indemnitee shall have the right to employ the
          Indemnitee's own counsel in connection with such claim, but the fees
          and expenses of such counsel incurred after notice from the
          Corporation or its assumption of the defense thereof shall be at the
          expense of the Indemnitee unless (i) the employment of counsel by the
          Indemnitee has been authorized by the Corporation, (ii) counsel to the
          Indemnitee shall have reasonably concluded that there may be a
          conflict of interest or position on any significant issue between the
          Corporation and the Indemnitee in the conduct of the defense of such
          action or (iii) the Corporation shall not in fact have employed
          counsel to assume the defense of such action, in each of which cases
          the fees and expenses of counsel for the Indemnitee shall be at the
          expense of the Corporation, except as otherwise expressly provided by
          this Article. The Corporation shall not be entitled, without the
          consent of the Indemnitee, to assume the defense of any claim brought
          by or in the right of the Corporation or as to which counsel for the
          Indemnitee shall have reasonably made the conclusion provided for in
          clause (ii) above.

     6.5  Advance of Expenses.  Subject to the provisions of Section 6.6 below,
          -------------------                                                  
          in the event that the Corporation does not assume the defense pursuant
          to Section 6.4 of this Article of any action, suit, proceeding or
          investigation of which the Corporation receives notice under this
          Article, any expenses (including attorneys' fees) incurred by an
          Indemnitee in defending a civil or criminal action, suit, proceeding
          or investigation or any appeal therefrom shall be paid by the
          Corporation in advance of the final disposition of such matter;
          provided, however, that the payment of such expenses incurred by an
          --------  -------
          Indemnitee in advance of the final disposition of such matter shall be
          made only upon receipt of an undertaking by or on behalf of the
          Indemnitee to repay all amounts so advanced in the event that it shall
          ultimately be determined that the Indemnitee is not entitled to be
          indemnified by the Corporation as

                                      -17-
<PAGE>
 
          authorized in this Article. Such undertaking shall be accepted without
          reference to the financial ability of the Indemnitee to make such
          repayment.

     6.6  Procedure for Indemnification.  In order to obtain indemnification or
          -----------------------------                                        
          advancement of expenses pursuant to Section 6.1, 6.2, 6.3 or 6.5 of
          this Article, the Indemnitee shall submit to the Corporation a written
          request, including in such request such documentation and information
          as is reasonably available to the Indemnitee and is reasonably
          necessary to determine whether and to what extent the Indemnitee is
          entitled to indemnification or advancement of expenses. Any such
          indemnification or advancement of expenses shall be made promptly, and
          in any event within 60 days after receipt by the Corporation of the
          written request of the Indemnitee, unless with respect to requests
          under Section 6.1, 6.2 or 6.5 the Corporation determines within such
          60-day period that the Indemnitee did not meet the applicable standard
          of conduct set forth in Section 1 or 2, as the case may be. Such
          determination shall be made in each instance by (a) a majority vote of
          the directors of the Corporation consisting of persons who are not at
          that time parties to the action, suit or proceeding in question
          ("disinterested directors"), whether or not a quorum, (b) a majority
          vote of a quorum of the outstanding shares of stock of all classes
          entitled to vote for directors, voting as a single class, which quorum
          shall consist of stockholders who are not at that time parties to the
          action, suit or proceeding in question, (c) independent legal counsel
          (who may, to the extent permitted by law, be regular legal counsel to
          the Corporation), or (d) a court of competent jurisdiction.

     6.7  Remedies.  The right to indemnification or advances as granted by this
          --------                                                              
          Article shall be enforceable by the Indemnitee in any court of
          competent jurisdiction if the Corporation denies such request, in
          whole or in part, or if no disposition thereof is made within the 60-
          day period referred to above in Section 6.6. Unless otherwise required
          by law, the burden of proving that the Indemnitee is not entitled to
          indemnification or advancement of expenses under this Article shall be
          on the Corporation. Neither the failure of the Corporation to have
          made a determination prior to the commencement of such action that
          indemnification is proper in the circumstances because the Indemnitee
          has met the applicable standard of conduct, nor an actual
          determination by the Corporation pursuant to Section 6.6 that the
          Indemnitee has not met such applicable standard of conduct, shall be a
          defense to the action or create a presumption the Indemnitee has not
          met the applicable standard of conduct. The indemnitee's expenses
          (including attorney' fees) incurred in connection with successfully
          establishing the Indemnitee's right to

                                      -18-
<PAGE>
 
          indemnification, in whole or in part, in any such proceeding shall
          also be indemnified by the Corporation.

     6.8  Subsequent Amendment.  No amendment, termination or repeal of this
          --------------------                                              
          Article or of the relevant provisions of the General Corporation Law
          of Delaware or any other applicable laws shall affect or diminish in
          any way the rights of any Indemnitee to indemnification under the
          provisions hereof with respect to any action, suit, proceeding or
          investigation arising out of or relating to any actions, transactions
          or facts occurring prior to the final adoption of such amendment,
          termination or repeal.

     6.9  Other Rights.  The indemnification and advancement of expenses
          ------------                                                  
          provided by this Article shall not be deemed exclusive of any other
          rights to which an Indemnitee seeking indemnification or advancement
          of expenses may be entitled under any law (common or statutory),
          agreement or vote of stockholders or disinterested directors or
          otherwise, both as to action in such person's official capacity and as
          to action in any other capacity while holding office for the
          Corporation, and shall continue as to an Indemnitee who has ceased to
          be a director or officer, and shall inure to the benefit of the
          estate, heirs, executors and administrators of the Indemnitee. Nothing
          contained in this Article shall be deemed to prohibit, and the
          Corporation is specifically authorized to enter into, agreements with
          officers and directors providing indemnification rights and procedures
          different from those set forth in this Article. In addition, the
          Corporation may, to the extent authorized from time to time by its
          Board of Directors, grant indemnification rights to other employees or
          agents of the Corporation or other persons serving the Corporation and
          such rights may be equivalent to, or greater or less than, those set
          forth in this Article.

     6.10 Partial Indemnification.  If an Indemnitee is entitled under any
          -----------------------                                         
          provision of this Article to indemnification by the Corporation for
          some or a portion of the expenses (including attorneys' fees),
          judgments, fines or amounts paid in settlement actually and reasonably
          incurred by such person or on such person's behalf in connection with
          any action, suit, proceeding or investigation and any appeal therefrom
          but not, however, for the total amount thereof, the Corporation shall
          nevertheless indemnify the Indemnitee for the portion of such expenses
          (including attorneys' fees), judgments, fines or amounts paid in
          settlement to which the Indemnitee is entitled.

     6.11 Insurance.  The Corporation may purchase and maintain insurance, at
          ---------                                                          
          its expenses, to protect itself and any director, officer, employee or
          agent

                                      -19-
<PAGE>
 
          of the Corporation or another corporation, partnership, joint venture,
          trust or other enterprise (including any employee benefit plan)
          against any expense, liability or loss incurred by such person in any
          such capacity, or arising out of such person's status as such, whether
          or not the Corporation would have the power to indemnify such person
          against such expense, liability or loss under the General Corporation
          Law of Delaware.

     6.12 Merger or Consolidation.  If the Corporation is merged into or
          -----------------------                                       
          consolidated with another corporation and the Corporation is not the
          surviving corporation, the surviving corporation shall assume the
          obligations of the Corporation under this Article with respect to any
          action, suit, proceeding or investigation arising out of or relating
          to any actions, transactions or facts occurring prior to the date of
          such merger or consolidation.

     6.13 Savings Clause.  If this Article or any portion hereof shall be
          --------------                                                 
          invalidated on any ground by any court of competent jurisdiction, then
          the Corporation shall nevertheless indemnity each Indemnitee as to any
          expenses (including attorneys' fees), judgements, fines and amounts
          paid in settlement in connection with any action, suit, proceeding or
          investigation, whether civil, criminal or administrative, including an
          action by or in the right of the Corporation, to the fullest extent
          permitted by any applicable portion of this Article that shall not
          have been invalidated and to the fullest extent permitted by
          applicable law.

     6.14 Definitions.  Terms used herein and defined in Section 145(h) and
          -----------                                                      
          Section 145(i) of the General Corporation Law of Delaware shall have
          the respective meanings assigned to such terms in such Section 145(h)
          and Section 145(i).

     6.15 Subsequent Legislation.  If the General Corporation Law of Delaware is
          ----------------------                                                
          amended after adoption of this Article to expand further the
          indemnification permitted to Indemnities, then the Corporation shall
          indemnify such persons to the fullest extent permitted by the General
          Corporation Law of Delaware, as so amended.

     SEVENTH: The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute and this Certificate of
Incorporation, and all rights conferred upon stockholders herein are granted
subject to this reservation.

                           ARTICLE 1  -  Stockholders
                           --------------------------

     1.1.  Place of Meetings.  All meetings of stockholders shall be held at 
           -----------------
such place within or without the State of Delaware as may be designated from
time to time by the Board of Directors or the President or, if not so
designated, at the registered office of the corporation.

     1.2.  Annual Meeting.  The annual meeting of stockholders for the election
           --------------
of directors and for the transaction of such other business as may properly be
brought before the meeting shall be held on a date to be fixed by the Board of
Directors or the President (which date shall not be a legal holiday in the place
where the meeting is to be held) at the time and place to be fixed by the Board
of Directors or the President and stated in the notice of the meeting. If no
annual meeting is held in accordance with the foregoing provisions, the Board of
Directors shall cause the meeting to be held as soon thereafter as convenient.
If no annual meeting is held in accordance with the foregoing provisions, a
special meeting may be held in lieu of the annual meeting, and any action taken
at that special meeting shall have the same effect as if it had been taken at
the annual meeting, and in such case all references in these By-laws to the
annual meeting of the stockholders shall be deemed to refer to such special
meeting.

     1.3.  Special Meetings.  Special meetings of stockholders may be called 
           ----------------
at any time by the President or by the Board of Directors. Business transacted
at any special meeting of stockholders shall be limited to matters relating to
the purpose or purposes stated in the notice of the meeting.

     1.4.  Notice of Meetings.  Except as otherwise provided by law, written 
           ------------------
notice of each meeting of stockholders, whether annual or special, shall be
given not less than 10 nor more than 60 days before the date of the meeting to
each stockholder entitled to vote at such meeting. The notices of all meetings
shall state the place, date and hour of the meeting. The notice of a special
meeting shall state, in addition, the purpose or purposes for which the meeting
is called. If mailed, notice is given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation.

     1.5.  Voting List.  The officer who has charge of the stock ledger of the
           -----------                                                        
corporation shall prepare, at least 10 days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during
<PAGE>
 
ordinary business hours, for a period of at least 10 days prior to the meeting,
at a place within the city where the meeting is to be held.  The list shall also
be produced and kept at the time and place of the meeting during the whole time
of the meeting, and may be inspected by any stockholder who is present.

     1.6.  Quorum.  Except as otherwise provided by law, the Certificate of
           ------                                                          
Incorporation or these By-laws, the holders of a majority of the shares (or, if
there are two or more classes of stock entitled to vote as separate classes, the
holders of a majority of the shares of such class) of the capital stock of the
corporation issued and outstanding and entitled to vote at the meeting, present
in person or represented by proxy, shall constitute a quorum for the transaction
of business.

     1.7.  Adjournments.  Any meeting of stockholders may be adjourned to any 
           ------------
other time and to any other place at which a meeting of stockholders may be held
under these By-laws by the stockholders present or represented at the meeting
and entitled to vote, although less than a quorum, or, if no stockholder is
present, by any officer entitled to preside at or to act as Secretary of such
meeting. It shall not be necessary to notify any stockholder of any adjournment
of less than 30 days if the time and place of the adjourned meeting are
announced at the meeting at which adjournment is taken, unless after the
adjournment a new record date is fixed for the adjourned meeting. At the
adjourned meeting, the corporation may transact any business which might have
been transacted at the original meeting.

     1.8.  Voting and Proxies.  Each stockholder shall have one vote for each 
           ------------------
share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
in the Certificate of Incorporation. Each stockholder of record entitled to vote
at a meeting of stockholders, or to express consent or dissent to corporate
action in writing without a meeting, may vote or express such consent or dissent
in person or may authorize another person or persons to vote or act for him by
written proxy executed by the stockholder or his authorized agent and delivered
to the Secretary of the corporation. No such proxy shall be voted or acted upon
after three years from the date of its execution, unless the proxy expressly
provides for a longer period.

     1.9.  Acting at Meeting.  When a quorum is present at any meeting, the 
           -----------------
holders of shares of stock representing a majority of the votes cast on a matter
(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of shares of stock of
that class representing a majority of the votes cast on a matter) shall decide
any matter to be voted upon by the stockholders at such meeting, except when a
different vote is required by express provision of law, the Certificate of
Incorporation or these By-Laws. When a quorum is present at any meeting, any
election of directors by stockholders shall be determined by a majority of the
votes cast on the election.

                                      -2-
<PAGE>
 
     1.10.  Action without Meeting.  Any action required or permitted to be 
            ----------------------
taken at any annual or special meeting of stockholders of the corporation may be
taken without a meeting, without prior notice and without a vote, if a consent
in writing, setting forth the action so taken, is signed by the holders of
outstanding stock (or, if there are two or more classes of stock entitled to
vote as separate classes, by the holders of outstanding stock of that class
entitled to vote on such action) having not less than the minimum number of
votes that would be necessary to authorize or take such action at a meeting at
which all shares entitled to vote on such action were present and voted. Prompt
notice of the taking of corporate action without a meeting by less than
unanimous written consent shall be given to those stockholders who are entitled
to vote on such action and have not consented in writing.


                            ARTICLE 2  -  Directors
                            -----------------------

     2.1.  General Powers.  The business and affairs of the corporation shall be
           --------------                                                       
managed by or under the direction of a Board of Directors, who may exercise all
of the powers of the corporation except as otherwise provided by law or the
Certificate of Incorporation.  In the event of a vacancy in the Board of
Directors, the remaining directors, except as otherwise provided by law, may
exercise the powers of the full Board until the vacancy is filled.

     2.2.  Number, Election and Qualification.
           ---------------------------------- 

           2.2.1.  The number of directors which shall constitute the whole 
     Board of Directors shall be eleven. The number of directors may be
     decreased at any time and from time to time either by the stockholders or
     by a majority of the directors then in office, but only to eliminate
     vacancies existing by reason of the death, resignation, removal or
     expiration of the term of one or more directors. The directors shall be
     elected at the annual meeting of stockholders by such stockholders as have
     the right to vote on such election. Directors need not be stockholders of
     the corporation.

           2.2.2.  As used in these By-laws, the term Class B Directors shall
     mean directors of the corporation who are elected directors in manner
     specified in Sections 2.2.3(b) and 2.2.3(c), the term Class A Directors
     shall mean directors of the corporation who are elected directors in the
     manner specified in Sections 2.2.3.(a) and the term Common Stock Directors
     shall mean directors of the corporation who are elected directors in the
     manner specified in Section 2.2.3.(d).

           2.2.3. So long as there are issued and outstanding shares of Class B-
     1 and Class B-2 Common Stock, the number of directors shall be set at

<PAGE>
 
Section 5 shall take place as soon as reasonably practicable at the principal
office of the Company, or at such other time and location as the parties to such
purchase may mutually determine.  In the event the price of any securities to be
purchased pursuant to this Section 5 is specified to be Fair Market Value, such
Fair Market Value shall be determined as of the date of the applicable
Termination Event.  At the closing of any purchase and sale pursuant to this
Section 5, the holder of securities to be sold shall deliver to the Company a
certificate or certificates representing the Shares, Warrants and Options to be

issued by the Company, bearing interest at the Prime Rate, all such interest and
principal to be payable at maturity and subordinated on such terms as may be
required by any agreement (a "Material Loan Agreement") to which the Company or

any of subsidiaries may be or hereafter become a party relating to indebtedness
for borrowed money in a principal amount outstanding (including, without
limitation, unused availability under a line of credit) in excess of $5,000,000,
which note shall be prepayable without premium or penalty.  The delivery of a
certificate or certificates for Shares, Warrants or Options by any Person
selling securities pursuant to this Section 5 shall be deemed a representation
and warranty by such Person that: (i) such Person has full right, title and
interest in and to such securities; (ii) such Person has all necessary power and
authority and has taken all necessary action to sell such securities as
contemplated; and (iii) such securities are free and clear of any and all liens
or encumbrances.  The Company shall have the right, but no obligation, to assign
to any holder of Bain Investor Shares all or any portion of its right to
purchase any securities pursuant to this Section 5.

     5.5.   Determination of Fair Market Value.  (a) For purposes of this
            ----------------------------------                           
Section 5, the term "Fair Market Value" shall mean, as of any date, the fair
value of any Share as of the applicable date on the basis of a sale of such
Share in an arms length private sale between a willing buyer and a willing
seller, neither acting under compulsion (or, in the case of a Warrant or Option,
the fair value of the Shares that may then be purchased by the holder of such
Warrant or Option upon exercise thereof, determined as described in this Section
5.5, minus the exercise price applicable thereto), as determined by the Board;
(b) at any time when more than 15% of the Shares then outstanding has been
offered and sold pursuant to one or more Public Offerings, the Fair Market Value
of any Share shall be equal to the average of the sum of the closing prices of
the Shares for the 30 trading days immediately prior to the date on which Share
becomes subject to repurchase under this Section 5. In determining Fair Market
Value, the Board shall (a) consider, in addition to other factors that it
determines in good faith to be relevant, the purchase price of the Shares in
recent (i) arms-length sales of Shares by the Company, (ii) transfers of Shares
by a Stockholder in an arms-length transaction and (b) not give effect to any
discount which may otherwise be attributable to the fact that such Shares which
are the subject of such valuation constitute less than a majority of the Shares
outstanding.

     5.6.  Period.  The foregoing provisions of this Section 5 shall expire on
           ------

the restrictions on transfer, vesting requirements or termination provisions

Company's 1995 Restricted Stock Plan, Equity Incentive Plan or other equity or
option plan pursuant to which such Share or Option was granted or other
governing documentation.

6.   "TAKE ALONG" RIGHTS.  Each holder of Shares, Warrants or Options hereby
agrees, if requested by the Bain Investor Majority Holders (which request shall

Section 6, a "Sale") a specified percentage (for purposes of this Section 6, the
              ----                                                              
"Sale Percentage") of the securities then owned by such holder to a third party
 ---------------                                                               
which is not a Bain Investor or an Affiliate of any Bain Investor Majority
Holder (for purposes of this Section 6, the "Proposed Buyer") in the manner and
                                             --------------                    
on the terms set forth in this Section 6 in connection with the Sale by such
Bain Investor (collectively, the "Proposed Bain Investor Seller") of the Sale
                                  -----------------------------             
Percentage of the total number of Bain Investor Shares held by all holders of
Bain Investor Shares on a fully diluted basis to the Proposed Buyer.

     6.1.  Procedure.  If the Bain Investor Majority Holders elect to exercise
           ---------                                                          
their rights under this Section 6, a notice (the "Come Along Notice") shall be
                                                  -----------------          
furnished by the Proposed Bain Investor Seller to each holder of Shares,
Warrants and Options.  The Come Along Notice shall set forth the principal terms
of the proposed Sale insofar as it relates to the Shares, including the Sale
Percentage and the purchase price.  No fee or additional consideration shall be
paid to a Bain Investor in connection with such Sale which is not contemplated
or permitted by the Management Agreement (as defined in Section 13) and relates
to services rendered by such Bain Investor or its Affiliates in connection
therewith.  If the Bain Investor Majority Holders consummate the Sale referred
to in the Come Along Notice, each other holder of Shares, Warrants or Options
(each a "Participating Seller") shall be bound and obligated to Sell the Sale
         --------------------                                             
Percentage of the Shares, Warrants and Options in the Sale on the same terms and
conditions with respect to each Share sold, as the Bain Investor shall Sell each
Bain Investor Share in the Sale, and, in the case of Warrants or Options, have
the opportunity to either (i) exercise such Warrants or Options (if then
exercisable) and participate in such sale as holders of Shares issuable upon
such exercise or (ii) upon the consummation of the Sale, receive in exchange for
such Warrants or Options (to the extent exercisable at the time of such Sale)
consideration equal to the amount determined by multiplying (1) the same amount
of consideration per Share received by the holders of the Shares of the same
class of common stock for which the Warrants or Option is exercisable in
connection with the Sale less the exercise price per share of such Warrants or
Option by (2) the number of Shares of such class represented by such rights.  If
at the end of the one hundred eightieth (180th) day following the date of the
effectiveness of the Come Along Notice the Proposed Bain Investor Seller has not
completed the Sale, each Participating Seller shall be released from his
obligation under the Come Along Notice, the Come Along Notice shall be null and
void, and it shall be necessary for a separate Come Along Notice to have been
furnished and the terms and provisions of this Section 6 separately complied
with, in order to consummate such Sale pursuant to this Section 6, unless the
failure to complete such Sale resulted from any failure by any Participating
Seller to comply in any material respect with the terms of this Section 6.

       6.2. Certain Legal Requirements.  In the event the consideration to be
            --------------------------                                       
paid in exchange for Shares in the proposed Sale pursuant to Section 6.1
includes any securities and the receipt thereof by any Stockholder as a
Participating Seller would require under applicable law (i) the registration or
qualification of such securities or of any person as a broker or dealer or agent
with respect to such securities or (ii) the provision to any participant in the
Sale of any information other than such information as would be required under
Regulation D of the Securities and Exchange Commission or similar rule then in
effect in an offering made pursuant to said Regulation D solely to "accredited
investors" as defined in said Regulation D, the Proposed Bain Investor Seller
may, but shall not be obligated to, cause to be paid to such Participating
Seller in lieu of such Securities, against surrender of the Shares, Warrants and
Options (in accordance with Section 6.4 hereof) which would have otherwise been
Sold by such Participating Seller to the Proposed Buyer in the Sale, an amount
in cash equal to the fair market value of the securities which such
Participating Seller would otherwise receive, as determined in good faith by the
Board.  Any attempt by the Proposed Bain Investor Seller to permit a
Participating Seller to receive such securities may be conditioned on such
Participating Seller executing such documents and instruments, and taking such
other actions (including without limitation, if required by the Proposed Bain
Investor Seller, agreeing to be represented during the course of such
transaction by a "purchaser representative" (as defined in Regulation D) in
connection with evaluating the merits and risks of the prospective investment
and acknowledging that he was so represented), as the Proposed Bain Investor
Seller shall reasonably request in order to permit such legal requirements to
have been complied with.

       6.3. Further Assurances. Each Participating Seller and each Stockholder
            ------------------                                                
to whom the Shares held by such Participating Seller (or Warrants or Options to
purchase such Shares) were originally issued, shall, whether in his capacity as
a Participating Seller, stockholder, officer or director of the Company, or
otherwise, take or cause to be taken all such actions as may be reasonably
requested in order expeditiously to consummate each Sale pursuant to Section
6.1. Each such Participating Seller or Stockholder agrees (i) to vote all Shares
with respect to which he holds power to vote in favor of any proposal to
stockholders in connection with the Sale which is approved by the holders of a
majority of the outstanding Shares entitled to vote with respect to such matter
and (ii) to execute and deliver such agreements as may be necessary for the
Participating Seller to be subject to the same terms and conditions with respect
to the Sale as apply to the Proposed Bain Investor Seller, including without
limitation, an agreement by such Participating Seller to be subject to such
purchase price escrow or adjustment provisions as may apply to Stockholders
generally and to be liable in respect of any individual representations,
warranties, agreements and indemnities to be given by selling Stockholders in
the Sale.

       6.4. Closing. The closing of a Sale pursuant to Section 6.1 shall take
            -------                                                          
place at such time and place as the Bain Investor Majority Holders shall specify
by notice to each Participating Seller. At the closing of any Sale under this
Section 6, each Participating Seller shall deliver the certificates evidencing
the Shares, Warrants or Options to be sold by such Participating Seller, duly
endorsed, or with stock powers or other appropriate instruments duly endorsed,
for transfer with signature guaranteed, free and clear of any liens or
encumbrances, with any stock transfer tax stamps affixed, against delivery of
the applicable consideration.

       6.5. Period. The foregoing provisions of this Section 6 shall expire on
            ------                                                            
the date of a Qualified Public Offering.

                       (b) An offer by the Proposed Seller to include, at the
            option of each Tag Along Offeree, in the Sale to the Proposed Buyer
            such number of Shares and Underlying Shares (not in any event to
            exceed the Sale Percentage of the total number of Shares and
            Underlying Shares held by such Tag Along Offeree) owned by each Tag
            Along Offeree determined in accordance with Section 7.1.2 hereof, on
            the same terms and conditions, with respect to each Share Sold, as
            the Proposed Seller shall Sell each of his, her or its Shares. No
            fee or additional consideration shall be paid to a Bain Investor in
            connection with such Sale which is not contemplated or permitted by
            the Management Agreement and relates to services rendered by such
            Bain Investor or its Affiliates in connection therewith.

            7.1.2.     Exercise. Each Tag Along Offeree desiring to accept the
                       --------
       offer contained in the Tag Along Notice shall send a written commitment
       to the Proposed Seller specifying the number of Shares and Underlying
       Shares (not in any event to exceed the Sale Percentage of the total
       number of Shares and Underlying Shares held by such Tag Along Offeree)
       which such Tag Along Offeree desires to have included in the Sale within
       30 days after the effectiveness of the Tag Along Notice (each a
       "Participating Seller"). Each Tag Along Offeree who has not so accepted
        --------------------
       such offer shall be deemed to have waived all of his or her rights with
       respect to the Sale, and the Proposed Seller and the Participating
       Sellers shall thereafter be free to Sell to the Proposed Buyer, at a
       price no greater than 105% of the price set forth in the Tag Along Notice
       and otherwise on terms not more favorable in any material respect to them
       than those set forth in the Tag Along Notice, without any further
       obligation to such non-accepting Tag Along Offerees. If, prior to
       consummation, the terms of such proposed Sale shall change with the
       result that the price shall be greater than 105% of the price set forth
       in the Tag Along Notice or the other terms shall be more favorable in any
       material respect than as set forth in the Tag Along Notice, it shall be
       necessary for a separate Tag Along Notice to have been furnished, and the
       terms and provisions of this Section 7 separately complied with, in order
       to consummate such proposed Sale pursuant to this Section 7.

                                      -15-
<PAGE>
 
            The acceptance of each Participating Seller shall be irrevocable
       except as hereinafter provided, and each such Participating Seller shall
       be bound and obligated to Sell in the Sale, on the same terms and
       conditions specified in the Tag Along Notice with respect to each of the
       Shares to be sold (including Underlying Shares), and on the same terms
       and conditions as apply to each of the Shares sold by the Proposed
       Seller, such number of Shares (including any Underlying Shares) as such
       Participating Seller shall have specified in such Participating Seller's
       written commitment. In the event the Proposed Seller shall be unable
       (otherwise than by reason of the circumstances described in Section 7.2)
       to obtain the inclusion in the Sale of all Shares (including Underlying
       Shares) which the Proposed Seller and each Participating Seller desires
       to have included in the Sale (as evidenced in the case of the Proposed
       Seller by the Tag Along Notice and in the case of each Participating
       Seller by such Participating Seller's written commitment), the number of
       Shares (including Underlying Shares) to be sold in the Sale by the
       Proposed Seller and each Participating Seller shall be reduced on a pro
       rata basis according to the proportion which the number of Shares
       (including Underlying Shares) which each such Seller desires to have
       included in the Sale bears to the total number of Shares desired
       (including Underlying Shares) by all such Sellers to have included in the
       Sale.

            If at the end of the ninetieth (90th) day following the date of the
       effectiveness of the Tag Along Notice the Proposed Seller has not
       completed the Sale as provided in the foregoing provisions of this
       Section 7.1, each Participating Seller shall be released from his
       obligations under his written commitment, the Tag Along Notice shall be
       null and void, and it shall be necessary for a separate Tag Along Notice
       to have been furnished, and the terms and provisions of this Section 7
       separately complied with, in order to consummate such Sale pursuant to
       this Section 7, unless the failure to complete such Sale resulted from
       any failure by any Tag Along Offeree to comply in any material respect
       with the terms of this Section 7.

       7.2. Excluded Transactions. Notwithstanding the preceding provisions of
            ---------------------                                             
this Section 7 and subject to the provisions of Section 7 and Section 8 below,
the preceding provisions of this Section 7 shall not restrict any Transfer
pursuant to the provisions of Section 6 or 7 of this Agreement, and no holder of
Shares shall have pursuant to the provisions of this Section 7 any right of
participation or otherwise with respect to any Transfer of Shares:

                     (a) to a Bain Investor;

                     (b) to an Affiliated Fund which exists as of the date of
            this Agreement or with respect to which the investment in such Bain
            Investor Shares does not represent more than 10% of assets under
            management provided;

                     (c) by a Bain Investor or an Affiliated Fund: (i) to any
            director, officer or employee of the Company or its principal
            subsidiary; or (ii) to any trust established for the benefit of its
            partners or pro rata to its partners;

                     (d) in a Public Offering or other Public Event or to the
            public under Rule 144;

                                      -16-
<PAGE>
 
                     (e) to a Transfer permitted by Section 4; or

                     (f) to a Transfer by a holder of Shares in an amount less
            than 1% of the aggregate capital stock outstanding at such time;

provided (except with respect to Section 7.2(d)) that such transferee shall have
- --------                                                                        
executed and delivered to the Company an agreement to be bound by this Agreement
to the same extent as the transferor and provided that no such transfer shall
result in the Company being required to register the transfer of such Shares or
other securities under the Securities Act or Exchange Act or any similar state
law.

       7.3. Termination. The foregoing provisions of this Section 7 shall
            -----------                                                  
terminate immediately following the closing of a Qualified Public Offering.

8.     CERTAIN ISSUANCES AND TRANSFERS, ETC. Each holder of Shares agrees that
it will not transfer any Shares to any Person unless the transferee has
delivered to the Company a written acknowledgment and agreement that the Shares
to be received by such transferee are subject to all of the provisions of this
Agreement (as Bain Investor Shares in the case of a transfer from a holder of
Bain Investor Shares, as Management Shares in the case of a transfer from a
holder of Management Shares, and as Physician Shares in the case of a transfer
from a holder of Physician Shares) and that such transferee is bound by and a
party to this Agreement to the same extent as if it were an original signatory
hereto as a Stockholder hereunder; provided, however, notwithstanding any other
                                   -----------------                           
provision of this Agreement, (i) Shares transferred pursuant to and in
accordance with Section 6 or 7 to any Proposed Buyer (as defined in such
Sections) hereof or in a Public Offering or to the public under Rule 144 shall
be conclusively deemed thereafter not to be Shares under this Agreement and not
to be subject to any of the provisions hereof or entitled to the benefit of any
of the provisions hereof, and (ii) any Shares acquired by a holder of Bain
Investor Shares shall upon such acquisition be deemed for all purposes hereof to
be Bain Investor Shares, of like kind with the other Shares held by such holder.
Without limiting the generality of the foregoing, in the event that a Bain
Investor transfers Shares, in accordance with the provisions of this Section 8,
to any Affiliated Fund, such Affiliated Fund shall be deemed for all purposes
hereunder to be a Bain Investor with all of the rights and obligations of an
Initial Bain Investor hereunder.

9.     REGISTRATION RIGHTS. The Company will perform and comply, and cause each
of its subsidiaries to perform and comply, with such of following provisions as
are applicable to it. Each holder of Shares will perform and comply with such of
the following provisions as are applicable to such holder.

       9.1. Piggyback Registration Rights.
            ----------------------------- 

            9.1.1.     Election. Whenever the Company proposes to register any
                       --------
       shares of its Common Stock for its own or others' account under the
       Securities Act for a public offering (each a "Public Offering"), the
                                                     ---------------
       Company shall furnish each holder of Shares prompt written notice of its
       intent to do so. Upon the request of any such holder given by notice to
       the Company within twenty (20) days after the effectiveness of such
       notice from the Company, the Company will use its best efforts to cause
       to be included in such

                                      -17-
<PAGE>

foregoing provisions of this Section 9.1.1, if the Company is advised in writing
in good faith by any managing underwriter of the securities being offered
pursuant to any Public Offering under this Section 9.1 (including, without
limitation, Sections 9.2.1 and 9.2.2) that the number of shares to be sold by
Persons other than the Company in such Public Offering is greater than the
number of such shares which can be included in such Public Offering without
adversely affecting such Public Offering, the Company may reduce pro rata (based
upon the number of Shares requested to be included by such Persons other than
the Company) the number of Shares offered for the accounts of such Persons other
than the Company to a number of Shares deemed satisfactory by such managing
underwriter; provided, however, that (i) the number of Shares offered for the
             -----------------                                               
account of the Bain Investors pursuant to Section 9.1.1 shall not be reduced to
an amount less than the percentage of the number of Shares offered equal to the
percentage of Shares outstanding owned by the Bain Investors and (ii) the number
of Shares offered for the account of the Bain Investors pursuant to Section
9.2.1 shall not be reduced unless and until all other Shares held by such
Persons other than the Bain Investors have been reduced.

       9.1.2.     Further Assurances. Holders of Shares participating in any
                  ------------------                                        
Public Offering shall take all such actions and execute all such documents and
instruments that are reasonably requested by the Company to effect the sale of
their Shares in such Public Offering, including without limitation being parties
to the underwriting agreement entered into by the Company and any other selling
stockholders in connection therewith (and being liable in respect of the
representations and warranties made by such holder in respect of its legal
capacity or due organization, authority to sell Shares being registered by such
holder and ownership (free and clear of liens) of such Shares), and any
indemnification agreements or "lock-up" agreements for the benefit of the
underwriters in such underwriting agreement; provided, however, that the
                                             -----------------          
aggregate amount of such liability shall not exceed the net proceeds to such
holder from the disposition of such Shares.

       9.1.3.     Expenses. The Company shall pay all expenses of the holders of
                  --------                                                      
Shares participating in any Public Offering pursuant to this Section 9.1, other
than underwriting discounts and commissions, if any, applicable transfer taxes,
if any, and fees and charges of any attorneys or other advisors (other than
attorneys and advisors retained by the Company to advise it in connection with
such Public Offering) retained by any such holders.

       9.1.4.     Excluded Transactions. Notwithstanding the preceding
                  ---------------------                               
provisions of this Section 9.1, no holder of Shares shall have any right of
participation or otherwise with respect to the following Public Offerings:

                  (a) Any Public Offering relating to employee benefit plans on
       Form S-8 or any similar form then in effect.

                  (b) Any Public Offering relating to the acquisition after the
       date hereof by the Company or any of its subsidiaries of any acquired
       businesses.

                       ---------------------------------------------------
       Shares. One or more holders of Bain Investor Shares that wish to register
       ------
       securities representing at least twenty-five percent (25%) of the sum of
       the total number of Bain Investor Shares then outstanding requested to be
       registered pursuant to this Section 9.2.1 ("Initiating Holders") may, by
                                                   ------------------
       notice to the Company specifying the intended method or methods of
       disposition, request that the Company effect the registration under the
       Securities Act of all or a specified part of the Registrable Securities
       held by such Initiating Holders. For purposes of this Agreement, the term
       "Registrable Securities" shall mean, at any time, Shares that have not
        ----------------------
       previously been sold in a Public Offering or in a "brokers transaction"
       within the meaning of Rule 144 and "Registrable Bain Investor Securities"
                                           ------------------------------------
       shall mean Registrable Securities constituting Bain Investor Shares. The
       Company will then use its best efforts to effect the registration under
       the Securities Act of the Registrable Securities which the Company has
       been requested to register by such Initiating Holders.

            9.2.2.     Form. Each registration requested pursuant to this
                       ----
       Section 9.2 shall be effected by the filing of a registration statement
       on Form S-1 (or any other form which includes substantially the same
       information as would be required to be included in a registration
       statement on such form as currently constituted), unless the use of a
       different form has been agreed to in writing by holders of at least a
       majority of the Registrable Securities initially requesting such
       registration (the "Majority Requesting Holders").
                          ---------------------------

            9.2.3.     Registrations Pursuant to Section 9.2. In the case of a
                       -------------------------------------
       registration pursuant to Section 9.2 hereof, whenever the Majority
       Requesting Holders shall request that such registration shall be effected
       pursuant to an underwritten offering, such registration shall be so
       effected, and all Registrable Bain Investor Securities to be included in
       such registration shall be included in such underwritten offering. If
       requested by such underwriters, the Company will enter into an
       underwriting agreement with such underwriters for such offering
       containing such representations and warranties by the Company and such
       other terms and provisions as are customarily contained in underwriting
       agreements with respect to secondary distributions, including, without
       limitation, customary indemnity and contribution provisions.

            9.2.4.     Number. The Company is obligated to effect only three
                       ------
       such registrations pursuant to this Section 9.2.

       9.3. Obligations of the Company. Whenever required under this Section 9
            --------------------------                                        
to use its best efforts to effect the registration of any Registrable
Securities, the Company shall, as expeditiously as reasonably possible: Prepare
and file with the SEC a registration statement with respect to such Registrable
Securities and use its best efforts to cause such registration statement to
become effective, and, upon the request of the holders of a majority of the
Registrable Securities registered thereunder, keep such registration statement
effective until the Holders have informed the Company in writing that the
distribution of their securities has been completed provided that the Company
shall not be required to keep any registration statement which is not

                                      -19-
<PAGE>
 
a shelf registration or similar registration (including any successor thereto
such as a Company registration) effective for a period of more than 30 days; and
shall:

            (a) Prepare and file with the SEC such amendments and supplements to
       such registration statement and the prospectus used in connection with
       such registration statement, and use its best efforts to cause each such
       amendment to become effective, as may be necessary to comply with the
       provisions of the 1933 Act with respect to the disposition of all
       securities covered by such registration statement.

            (b) Furnish to the Holders such reasonable number of copies of a
       prospectus, including a preliminary prospectus, in conformity with the
       requirements of the 1933 Act, and such other documents as they may
       reasonably request in order to facilitate the public offering of
       Registrable Securities owned by them.

            (c) Use its best efforts to register or qualify the securities
       covered by such registration statement under such securities or Blue Sky
       laws of such jurisdictions as shall be reasonably requested by the
       Holders provided that the Company shall not be required to register in
       any jurisdictions which require it, in connection therewith or as a
       condition thereto, to qualify to do business or to file a general consent
       to service of process or to subject itself to taxation in any such states
       or jurisdiction.

            (d) In the event of any underwritten public offering, enter into and
       perform its obligations under an Underwriting Agreement, in which the
       Company addresses its representations and warranties to the underwriters
       and the Holders participating in such offering, with the managing
       underwriter of such offering. Each Holder participating in such
       underwriting shall also enter into and perform its obligations under such
       Underwriting Agreement, including furnishing any opinion of counsel or
       entering into a lock-up and indemnification agreement reasonably
       requested by the managing underwriter.

            (e) Notify each Holder of Registrable Securities covered by such
       registration statement, at any time when a prospectus relating thereto
       covered by such registration statement is required to be delivered under
       the 1933 Act, of the happening of any event as a result of which the
       prospectus included in such registration statement, as then in effect,
       includes an untrue statement of a material fact or omits to state a
       material fact required to be stated therein or necessary to make the
       statements therein not misleading in the light of the circumstances then
       existing and promptly file such amendments and supplements which may be
       required pursuant to subparagraph (b) of this Section 9.3 on account of
       such event and use its best efforts to cause each such amendment and
       supplement to become effective.

            (f) Furnish, at the request of any Holder requesting registration of
       Registrable Securities pursuant to this Section 9, on the date that such
       Registrable

                                      -20-
<PAGE>
 
       Securities are delivered to the underwriters for sale in connection with
       a registration pursuant to this Section 9, if such securities are being
       sold through underwriters, or, if such securities are not being sold
       through underwriters on the date that the registration statement with
       respect to such securities becomes effective, (i) an opinion or opinions,
       dated such date, of the counsel representing the Company for the purposes
       of such registration, in form and substance as is customarily given by
       company counsel to the underwriters in an underwritten public offering,
       addressed to the underwriters, if any, and to the Holders requesting
       registration of Registrable Securities and (ii) a letter dated such date,
       from the independent certified public accountant of the Company, in form
       and substance as is customarily given by independent certified public
       accountants to underwriters in an underwritten public offering, addressed
       to the underwriters, if any, and to the Holders requesting registration
       of Registrable Securities.

            (g) Apply for listing and use its best efforts to list the
       Registrable Securities being registered on any national securities
       exchange on which a class of the Company's equity securities is listed
       or, if the Company does not have a class of equity securities listed on a
       national securities exchange, apply for qualification and use its best
       efforts to qualify the Registrable Securities being registered for
       inclusion on the NASDAQ National Market System.

            (h) Without in any way limiting the types of registrations to which
       this Section 9 shall apply, in the event that the Company shall effect a
       "shelf registration" under Rule 415 promulgated under the 1933 Act, the
       Company shall take all necessary action, including, without limitation,
       the filing of post-effective amendments, to permit the Holders, who have
       exercised their rights under Section 9. 1, to maintain the inclusion of
       their Registrable Securities in such registration in accordance with the
       terms of this Section 9.

fact required to be stated therein or necessary to make the statements therein
not misleading, and will reimburse such Covered Person for any legal or any
other expenses incurred by it in connection with investigating or defending any
such loss, claim, damage, liability, action or proceeding; provided, however,
                                                           ----------------- 
that the Company shall not be liable to any Covered Person in any such case to
the extent that any such loss, claim, damage, liability, action or proceeding
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in such registration statement, any such
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement, incorporated document or other such disclosure document in reliance
upon and in conformity with written information furnished to the Company through
an instrument duly executed by such Covered Person specifically stating that it
is for use in the preparation thereof. The indemnities of the Company and of its
subsidiaries contained in this Section 9.4.1 shall remain in full force and
effect regardless of any investigation made by or on behalf of such Covered
Person and shall survive any transfer of securities.

       9.4.2.     Indemnities to the Company. The Company may require, as a
                  --------------------------                               
condition to including any securities in any registration statement filed
pursuant to this Section 9, that the Company shall have received an undertaking
satisfactory to it from each prospective seller of such securities, to indemnify
and hold harmless the Company, each director of the Company, each officer of the
Company who shall sign such registration statement and each other Person (other
than such seller), if any, who controls the Company within the meaning of
Section 15 of the Securities Act, with respect to any statement in or omission
from such registration statement, any preliminary prospectus or final prospectus
included therein, or any amendment or supplement thereto, or any document
incorporated therein, if such statement or omission was made in reliance upon
and in conformity with written information furnished to the Company through an
instrument executed by such seller specifically stating that it is for use in
the preparation of such registration statement, preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement, or incorporated
document. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Company or any such director, officer
or controlling Person and shall survive any transfer of securities.

       9.4.3.     Third Party Claims. Each party entitled to indemnification
                  ------------------                                        
under this Agreement (the "Indemnified Party") shall give notice to the party
required to provide indemnification (the "Indemnifying Party") promptly after
such Indemnified Party has actual knowledge of any claim as to which indemnity
may be sought, and shall permit the Indemnifying Party to assume the defense of
any such claim or any litigation resulting therefrom; provided, that counsel for
                                                      --------                  
the Indemnifying Party, who shall conduct

                                      -22-
<PAGE>
 
the defense of such claim or litigation, shall be approved by the Indemnified
Party (whose approval shall not be unreasonably withheld); and, provided,
                                                                -------- 
further, that  the failure of any Indemnified Party to give notice as provided
- -------                                                                       
herein shall not relieve the Indemnifying Party of its obligations under this
Section 9. The Indemnified Party may participate in such defense at such party's
expense; provided, however, that the Indemnifying Party shall pay such expense
         -----------------                                                    
if representation of such Indemnified Party by the counsel retained by the
Indemnifying Party would be inappropriate due to actual or potential differing
interests between the Indemnified Party and any other party represented by such
counsel in such proceeding.  In Indemnifying Party, in the defense of any such
claim or litigation shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect of such
claim or litigation, and no Indemnified Party shall consent to entry of any
judgment or settle such claim or litigation without the prior written consent of
the Indemnifying Party.

       9.4.4.     Contribution. If the indemnity provided for in Sections 9.4.1
                  ------------                                                 
or 9.4.2 is available, each Indemnified Party will be indemnified thereunder to
the full extent provided in such section without regard to the relative fault of
the Indemnifying Party or the Indemnified Party or the other equitable
considerations referenced in this Section 9.4.4. If the indemnification provided
for in Sections 9.4.1 or 9.4.2 hereof is unavailable to a party that would have
been an Indemnified Party under any such Section in respect of any losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
referred to therein, then each party that would have been an Indemnifying Party
thereunder shall, in lieu of indemnifying such Indemnified Party, contribute to
the amount paid or payable by such Indemnified Party as a result of such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof) in
such proportion as is appropriate to reflect the relative fault of such
Indemnifying Party on the one hand and such Indemnified Party on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof).
The relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by such Indemnifying Party or such Indemnified Party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The parties agree that it would not be just
or equitable if contribution pursuant to this Section 9.4.4 were determined by
pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the preceding sentence.
The amount paid or payable by a contributing party as a result of the losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
referred to above in this Section 9.4.4 shall include any legal or other
expenses reasonably incurred by such Indemnified Party in connection with
investigating or defending any such action or claim. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.

           9.4.5.  Limitation on Liability of Holders of Registrable Securities.
                   ------------------------------------------------------------
       The liability of each holder of Registrable Securities in respect of any
       indemnification or contribution obligation of such holder arising under
       this Section 9.4 shall not in any event exceed an amount equal to the net
       proceeds to such holder (after deduction of all underwriters' discounts
       and commissions and all other expenses paid by such holder in connection
       with the registration in question) from the disposition of the
       Registrable Securities disposed of by such holder pursuant to such
       registration.

       9.5. Selection of Underwriter. Any and all underwriters to be engaged in
            ------------------------                                           
connection with any public offering of Shares pursuant to a registration
effected pursuant to Section 9.2 shall be selected by the Bain Investors and
shall be reasonably acceptable to the Company.

       9.6. Lock-up. Each holder of Shares (including Underlying Shares) agrees
            -------                                                            
that upon the request of the underwriters managing any underwritten Public
Offering, it shall not Transfer any Shares (including Underlying Shares) for a
period beginning not more than seven days immediately preceding and ending not
more than 180 days following any Public Offering without the prior written
consent of the underwriters, if any, managing the offering.

       9.7. Limitations on Other Registration Rights. From and after the date of
            ----------------------------------------                            
this Agreement, the Company shall not, without the prior written consent of the
holders of a majority of the Bain Investor Shares then outstanding, enter into
any agreement with any holder or prospective holder of any securities of the
Company relating to registration rights unless such agreement includes to the
extent the agreement would allow such holder or prospective holder to include
such securities in any registration filed under Section 9.1 or 9.2 hereof, a
provision that such holder or prospective holder may include such securities in
any such registration only to the extent that the inclusion of its securities
will not reduce the amount of the Registrable Securities, and the amount of the
Registrable Bain Investor Securities of the Holders and the Bain Investors which
would otherwise be included and does otherwise not diminish the rights provided
in this Section 9 above.

            In the event of any conflict between this Section 9 and any
       agreement to which the Company or its subsidiaries is a party or by which
       any of them are bound, the provisions of this Section 9 shall govern.

       9.8. Availability of Information. If the Company shall have filed a
            ---------------------------                                   
registration statement pursuant to the requirements of Section 12 of the
Exchange Act or a registration statement pursuant to the requirements of the
Securities Act, the Company shall comply with the reporting requirements of
Sections 13 and 15(d) of the Exchange Act and shall comply with all other public
information reporting requirements of the Commission (including Rule 144
promulgated by the Commission under the Securities Act) from time to time in
effect and relating to the availability of an exemption from the Securities Act
for the sale of any Shares. The Company shall also cooperate with each holder of
any Shares in supplying such information as may be necessary for such holder to
complete and file any information reporting forms presently or hereafter
required by the Commission as a condition to the availability of an exemption
from the Securities Act for the sale of any Shares.

the event of any breach or violation of this Agreement or any default hereunder
by the Company or any holder of Shares, Warrants or Options. The parties
acknowledge and agree that in the event of any breach of this Agreement, in

hereto shall be entitled to specific performance of the obligations of the other
parties hereto and, in addition, to such other equitable remedies (including,
without limitation, preliminary or temporary relief) as may be appropriate in
the circumstances.

       10.2.  Deposit. Without limiting the generality of Section 10.1, if any
              -------

sold pursuant to any provision of this Agreement in accordance with the terms
hereof, the Company or other Person entitled to purchase such securities may, at
its option, in addition to all other remedies it may have, deposit the purchase
price for such Shares with any national bank or trust company having combined
capital, surplus and undivided profits in excess of one hundred million dollars
($100,000,000) and which has agreed to act as escrow agent in the manner
contemplated by this Section 10.2 and shall furnish or make available to all
interested Persons satisfactory evidence of such deposit and thereupon the
Company shall cancel on its books the certificate or certificates representing
such securities and, in the case of any such purchase of securities by a Person
other than the Company issue, in lieu thereof and in the name of such Person, a
new certificate or certificates representing such securities, and thereupon all

terminate. Thereafter, upon delivery to the Company by such Non-Complying
Stockholder of the certificate or certificates evidencing such securities (duly
endorsed, or with stock powers or other appropriate instruments of transfer duly
endorsed, for transfer, with signature guaranteed, free and clear of any liens
or encumbrances, and with any stock transfer tax stamps affixed), the Company
shall instruct the escrow agent referred to above to deliver the purchase price

any such interest to accrue to the Person who deposited the purchase price for
such securities) to such Non-Complying Stockholder.

11.    LEGENDS. Each certificate representing Shares shall have the following
legend endorsed conspicuously thereupon:

            "The securities represented by this certificate were issued in a

       otherwise transferred in the absence of an effective registration under
       the Act covering the transfer or an opinion of counsel, satisfactory to
       the issuer, that registration under the Act is not required.

             The shares of stock represented by this certificate are subject to
       restrictions on transfer and requirements of sale set forth in the
       Stockholders Agreement dated as of _________ 1996, as amended and in
       effect from time to time. The Company will furnish a copy of such

                            STOCKHOLDERS' AGREEMENT
                            -----------------------


     AGREEMENT made this 9th day of August, 1996, between Physicians Quality
Care, Inc., a Delaware corporation (the "Company"), and the Stockholders of the
Company named on the signature page of this Agreement (the "Physicians").

     WHEREAS, the Company and the Physicians are parties to either (i) a merger
agreement or (ii) an asset purchase agreement and an affiliation agreement (the
"Agreements") that, among other things, provide for the issuance of shares of
common stock, par value $0.01 per share (the "Common Stock"), of the Company
(any Common Stock beneficially owned by such Physicians whether now or
hereinafter acquired being referred to herein as the "Shares").

     WHEREAS, the Company and the Physicians agree that the Shares shall be
subject to the restrictions on transfer set forth herein.

     NOW THEREFORE, for valuable consideration, receipt and sufficiency of which
is hereby acknowledged, the parties hereto agree as follows:

     1.  Restrictions on Transfer.
         ------------------------ 

         (a) Until August 9, 1998, no Physician shall, directly or indirectly,
offer, sell, assign, transfer, grant a participation in, pledge, or otherwise
dispose of, or encumber any of the Shares, or any interest therein (each, a
"Transfer"); unless and until such Transfer has been approved by the Company (it
being understood that the Company intends to consent to such Transfer (subject
to the Company's rights under Sections 2 and 3 hereof) unless the Company
reasonable concludes that the Transfer, together with the Transfers by other
shareholders of the Company, may cause any merger pursuant to which such
Physician becomes a stockholder of the Company not to qualify as a tax-free
reorganization pursuant to Section 365 of the Internal Revenue Code of 1986, as
amended).

         (b) Subject to Section 1(a), a Physician may Transfer Shares (i) only
in accordance with Section 2 below or (ii) to (A) an individual, partnership,
joint venture, corporation, company, trust, estate, unincorporated association
or other entity of whatever nature which is directly or indirectly controlled by
such Physician, (B) any family member of such Physician or such Physician's
family members, and (C) a third party granted an interest in the Shares in the
will of such Physician or by the laws of descent or distribution (each
transferee as set forth in clauses (A)-(C), a "Permitted Transferee"); provided
                                                                       --------
that, such Shares shall remain subject to this Agreement (including without
- ----
limitation the restrictions on transfer set forth in this Section 1) and such
Permitted Transferee shall, as a condition to such Transfer, deliver to the
Company a written instrument confirming that such Permitted Transferee shall be
bound by all of the terms and conditions of this Agreement.
<PAGE>
 
     2.  Right of First Refusal.
         ---------------------- 

         (a) If a Physician proposes to Transfer any Shares other than as set
forth in paragraph 2(d) below, then the Physician shall first give written
notice of the proposed transfer (the "Transfer Notice") to the Company. The
Transfer Notice shall name the proposed transferee and state the number of such
Shares the Physician proposes to transfer the ("Offered Shares"), the price per
share and all other material terms and conditions of the Transfer.

         (b) For sixty (60) days following its receipt of such Transfer Notice,
the Company shall have the option to purchase all (but not less than all) of the
Offered Shares at the price and upon the terms set forth in the Transfer Notice.
In the event the Company elects to purchase all of the Offered Shares, it shall
give written notice of such election to the Physician within such sixty (60) day
period. Within ten (10) days after receipt of such notice, the Physician shall
tender to the Company at its principal offices the certificate or certificates
representing the Offered Shares, duly endorsed in blank by the Physician or with
duly endorsed stock powers attached thereto, all in form suitable for transfer
of the Offered Shares to the Company. Upon receipt of such certificate or
certificates, the Company shall deliver or mail to the Physician a check in
payment of the purchase price for the Offered Shares; provided that if the terms
                                                      -------------
of payment set forth in the Transfer Notice were other than cash against
delivery, the Company may pay for the Offered Shares on the same terms and
conditions as were set forth in the Transfer Notice.

         (c) If the Company does not elect to acquire all of the Offered Shares,
the Physician may, within the sixty (60) day period following the expiration of
the rights granted to the Company under subsection (b) above, transfer the
Offered Shares to the proposed transferee or any other transferee, provided that
                                                                   -------------
such transfer shall not be on terms and conditions more favorable to the
transferee than those contained in the Transfer Notice. Notwithstanding any of
the above, all Offered Shares transferred pursuant to this Section 2 shall
remain subject to this Agreement (including without limitation the restrictions
on transfer set forth in Section 1 and the right of first refusal set forth in
this Section 2) and such transferee shall, as a condition to such transfer,
deliver to the Company a written instrument confirming that such transferee
shall be bound by all of the terms and conditions of this Agreement.

         (d) The following transactions shall be exempt from the provisions of
this Section 2:

             (i)   A Transfer of Shares to or for the benefit of a Permitted
Transferee;

                                      -2-
<PAGE>
 
             (ii)  Any Transfer pursuant to an effective registration statement
filed by the Company under the Securities Act of 1933, as amended (the
"Securities Act"); and

             (iii) The sale of all or substantially all of the shares of capital
stock of the Company (including pursuant to a merger or consolidation);
provided, however, that in any such case, unless the provisions of this Section
- --------  -------                                                              
2 shall be thereby terminated pursuant to subsection (f) below, such Shares
shall remain subject to this Agreement (including without limitation the
restrictions on transfer set forth in Section 1 and the right of first refusal
set forth in this Section 2) and such transferee shall, as a condition to such
Transfer, deliver to the Company a written instrument confirming that such
transferee shall be bound by all of the terms and conditions of this Agreement.

         (e) The Company may assign its rights to purchase Shares in any
particular transaction under this Section 2 to one or more persons or entities.

         (f) The provisions of this Section 2 shall terminate upon the earlier
of the following events:

             (i)   The closing of the sale of shares of Common Stock in a public
offering pursuant to an effective registration statement filed by the Company
under the Securities Act; or

             (ii)  upon the sale of all or substantially all of the capital
stock, assets or business of the Company, by merger, consolidation, sale of
assets or otherwise.

     3.  Right of the Company to Reacquire The Shares.  In the event that a
         --------------------------------------------                      
Physician ceases to be an employee of Medical Care Partners, P.C.  or another
professional corporation affiliated with the Company at any time prior to August
9, 1999, the Company shall have the right, exercisable within 30 days of such
termination, to require such Physician to sell all Shares then held by such
Physician to the Company at their Fair Market Value.  For purposes of the
foregoing, the Fair Market Value of the Shares shall mean: (a) if the Shares are
listed on a national securities exchange or the National Association of
Securities Dealers, Inc.'s National Market System, the last sales price on the
date of termination and (b) if the Shares are not listed on a national
securities exchange or the National Market System at the fair value thereof as
determined by an independent financial advisor reasonably satisfactory to the
Company and the Physician based upon recent sale of shares of the Company's
Common Stock, or in the absence of any such sale, sales of the equity securities
of comparable companies.  The Company's rights pursuant to this Section 3

                                      -3-
<PAGE>
 
shall not otherwise restrict the Physician's ability to Transfer the Share and
shall not be binding upon any subsequent holder of the Shares.

     4.  Effect of Prohibited Transfer.  The Company shall not be required (a)
         -----------------------------                                        
to transfer on its books any of the Shares which shall have been sold or
transferred in violation of any of the provisions set forth in this Agreement,
or (b) to treat as owner of such Shares or to pay dividends to any transferee to
whom any such Shares shall have been so sold or transferred.

     5.  Restrictive Legend.
         ------------------ 

         (a) All certificates representing Shares shall have affixed thereto a
legend in substantially the following form, in addition to any other legends
that may be required under federal or state securities laws:

         restrictions on transfer and an option to purchase set forth in a
         certain Stock Restriction Agreement between the corporation and the
         registered owner of these shares (or his predecessor in interest), and
         such Agreement is available for inspection without charge at the office
         of the Secretary of the corporation."

         (b) An original copy of this Agreement, duly executed by each of the
parties hereto, shall be delivered to the Secretary of the Company and
maintained at the principal executive office of the Company and made available
for inspection by any person requesting it.

         ------

Joint Escrow Instructions shall be delivered to the Secretary of the Company, as
escrow agent thereunder.  Each Physician shall deliver to such escrow agent a
stock assignment duly endorsed in blank and hereby instructs the Company to
deliver to such escrow agent, on behalf of such Physician, the certificate(s)
evidencing the Shares.  Such materials shall be held by such escrow agent
pursuant to the terms of such Joint Escrow Instructions.

     7.  Severability.  The invalidity or unenforceability of any provision of
         ------------

authority or rights of the parties executing or delivering or purporting to

                         REGISTRATION RIGHTS AGREEMENT
                         -----------------------------


     This Agreement dated as of August 9, 1996 is entered into by and among
Physicians Quality Care, Inc., a Delaware corporation (the "Company"), and the
shareholders of the Company listed on the signature page of this Agreement (the
"Physicians").

     WHEREAS, the Company and each Physician have entered into either (1) a
merger agreement or (ii) an asset purchase agreement and an affiliation
agreement of even date herewith (the "Agreements"); and

     WHEREAS, the Company and the Physicians desire to provide for certain
arrangements with respect to the registration of shares of capital stock of the
Company under the Securities Act of 1933;

     NOW, THEREFORE, in consideration of the mutual promises and covenants
contained in this Agreement, the parties hereto agree as follows:

     1.   Certain Definitions.  As used in this Agreement, the following terms
          -------------------                                                 
shall have the following respective meanings:

          "Commission" means the Securities and Exchange Commission, or any 
           ----------
other Federal agency at the time administering the Securities Act.

          "Common Stock" means the common stock, $0.01 par value per share, of 
           ------------
the Company.

          "Exchange Act" means the Securities Exchange Act of 1934, as amended,
           ------------
or any similar Federal statute, and the rules and regulations of the Commission
issued under such Act, as they each may, from time to time, be in effect.

          "Registration Statement" means a registration statement filed by the
           ----------------------                                             
Company with the Commission for a public offering and sale of Common Stock
(other than a registration statement on Form S-B or Form S-4, or their
successors, or any other form for a similar limited purpose, or any registration
statement covering only securities proposed to be issued in exchange for
securities or assets of another corporation).

          "Registration Expenses" means the expenses described in Section 4.
           ---------------------                                            

          "Registrable Shares" means (i) the shares of Common Stock issued or
           ------------------                                                
issuable upon conversion of the capital stock of the Company issued to the
Physicians pursuant to the Affiliation Agreements and (ii) any other shares of
Common Stock issued in respect of such shares (because of stock splits, stock
dividends, reclassifications, recapitalizations, or similar events); provided,
                                                                     ---------
however,
- ------- 
<PAGE>
 
that shares of Common Stock which are Registrable Shares shall cease to be
Registrable Shares upon any sale or transfer whether pursuant to a Registration
Statement, Rule 144 under the Securities Act or otherwise.

          "Securities Act" means the Securities Act of 1933, as amended, or any
           --------------                                                      
similar Federal statute, and the rules and regulations of the Commission issued
under such Act, as they each may, from time to time, be in effect.

          "Shares" shall mean the Shares of Common Stock issued upon conversion 
           ------
of the capital stock of the Company issued to the Physicians pursuant to the
Agreements.

          "Stockholders" means the Physicians and any persons or entities to 
           ------------ 
whom the rights granted under this Agreement are transferred by a Stockholder
pursuant to Section 11 of this Agreement.

     2.   Registration.
          ------------ 

          (a)  Whenever the Company proposes to file a Registration Statement
registering shares of its Common Stock under the Securities Act at any time and
from time to time, it will, prior to such filing, give written notice to all
Stockholders of its intention to do so and, upon the written request of a
Stockholder or Stockholders given within twenty (20) days after the Company
provides such notice (which request shall state the intended method of
disposition of such Registrable Shares), the Company shall use its best efforts
to cause all Registrable Shares which the Company has been requested by such
Stockholder or Stockholders to register to be registered under the Securities
Act to the extent necessary to permit their sale or other disposition in
accordance with the intended methods of distribution specified in the request of
such Stockholder or Stockholders; provided that the Company shall have the right
to postpone or withdraw any registration effected pursuant to this Section 2
without obligation to any Stockholder; provided, further, that a Physician's
rights under this Agreement shall not apply to a Registration Statement filed in
connection with the Company's initial public offering of its Common Stock
registered under the Securities Act.

          (b)  In connection with any registration under this Section 2
involving an underwriting, the Company shall not be required to include any
Registrable Shares in such registration unless the holders thereof accept the
terms of the underwriting as agreed upon between the Company and the
underwriters selected by it. If in the opinion of the managing underwriter it is
appropriate because of marketing factors to limit the number of Registrable
Shares to be included in the offering, then the Company shall be required to
include in the registration only that number of Registrable Shares, if any,
which the managing underwriter believes should be included therein; provided
that if the number of Registrable Shares to be included in the offering in
accordance with the foregoing is less than the total number of shares which the
holders of Registrable Shares have requested to be
<PAGE>
 
included, then the holders of Registrable Shares who have requested registration
and other holders of securities entitled to include them in such registration
shall participate in the registration pro rata based upon their total ownership
of shares of Common Stock (giving effect to the conversion into Common Stock of
all securities convertible thereinto).  If any holder would thus be entitled to
include more securities than such holder requested to be registered, the excess
shall be allocated among other requesting holders pro rata in the manner
described in the preceding sentence.

     3.   Registration Procedures.  If and whenever the Company is required by
          -----------------------                                             
the provisions of this Agreement to use its best efforts to effect the
registration of any of the Registrable Shares under the Securities Act, the
Company shall:

          (a)  file with the Commission a Registration Statement with respect to
such Registrable Shares and use its best efforts to cause that Registration
Statement to become and remain effective;

          (b)  as expeditiously as possible prepare and file with the Commission
any amendments and supplements to the Registration Statement and the prospectus
included in the Registration Statement as may be necessary to keep the
Registration Statement effective, in the case of a firm commitment underwritten
public offering, until each underwriter has completed the distribution of all
securities purchased by it and, in the case of any other offering, until the
earlier of the sale of all Registrable Shares covered thereby or one hundred
twenty (120) days after the effective date thereof;

          (c)  as expeditiously as possible furnish to each selling Stockholder
such reasonable numbers of copies of the prospectus, including a preliminary
prospectus, in conformity with the requirements of the Securities Act, and such
other documents as the selling Stockholder may reasonably request in order to
facilitate the public sale or other disposition of the Registrable Shares owned
by the selling Stockholder; and

          (d)  as expeditiously as possible use its best efforts to register or
qualify the Registrable Shares covered by the Registration Statement under the
securities or Blue Sky laws of such states as the selling Stockholders shall
reasonably request, and do any and all other acts and things that may be
necessary or desirable to enable the selling Stockholders to consummate the
public sale or other disposition in such states of the Registrable Shares owned
by the selling Stockholder; provided, however, that the Company shall not be
                            -----------------                               
required in connection with this paragraph (d) to qualify as a foreign
corporation or execute a general consent to service of process in any
jurisdiction.

     If the Company has delivered preliminary or final prospectuses to the
selling Stockholders and after having done so the prospectus is amended to
comply with the requirements of the Securities Act, the Company shall promptly
notify the selling Stockholders and, if requested, the selling Stockholders
shall immediately cease
<PAGE>
 
making offers of Registrable Shares and return all prospectuses to the Company.
The Company shall promptly provide the selling Stockholders with revised
prospectuses and, following receipt of the revised prospectuses, the selling
Stockholders shall be free to resume making offers of the Registrable Shares.

     4.   Allocation of Expenses.  The Company will pay all Registration 
          ----------------------                                          
Expenses of all registrations under this Agreement. For purposes of this Section
4, the term "Registration Expenses" shall mean all expenses incurred by the
Company in complying with this Agreement, including, without limitation, all
registration and filing fees, exchange listing fees, printing expenses, fees and
expenses of counsel for the Company, state Blue Sky fees and expenses, and the
expense of any special audits incident to or required by any such registration.
Registration Expenses shall not include any underwriting discounts, selling
commissions or the fees and expenses of selling Stockholders' own counsel.

     5.   Indemnification and Contribution.
          -------------------------------- 

          (a)  In the event of any registration of any of the Registrable Shares
under the Securities Act pursuant to this Agreement, the Company will indemnify
and hold harmless the seller of such Registrable Shares, each underwriter of
such Registrable Shares, and each other person, if any, who controls such seller
or underwriter within the meaning of the Securities Act or the Exchange Act
against any losses, claims, damages or liabilities, joint or several, to which
such seller, underwriter or controlling person may become subject under the
Securities Act, the Exchange Act, state securities or Blue Sky laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any Registration Statement
under which such Registrable Shares were registered under the Securities Act,
any preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or supplement to such Registration Statement, or
arise out of or are based upon the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading; and the Company will reimburse such seller, underwriter
and each such controlling person for any legal or any other expenses reasonably
incurred by such seller, underwriter or controlling person in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the Company will not be liable in any such case to the
- -----------------                                                             
extent that any such loss, claim, damage or liability arises out of or is based
upon any untrue statement or omission made in such Registration Statement,
preliminary prospectus or final prospectus, or any such amendment or supplement,
in reliance upon and in conformity with information furnished to the Company, in
writing, by or on behalf of such seller, underwriter or controlling person
specifically for use in the preparation thereof.

          (b)  In the event of any registration of any of the Registrable Shares
under the Securities Act pursuant to this Agreement, each seller of Registrable
Shares,
<PAGE>
 
severally and not jointly, will indemnify and hold harmless the Company, each of
its directors and officers and each underwriter (if any) and each person, if
any, who controls the Company or any such underwriter within the meaning of the
Securities Act or the Exchange Act, against any losses, claims, damages or
liabilities, joint or several, to which the Company, such directors and
officers, underwriter or controlling person may become subject under the
Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement under which
such Registrable Shares were registered under the Securities Act, any
preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or supplement to the Registration Statement, or
arise out of or are based upon any omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, if the statement or omission was made in reliance upon
and in conformity with information relating to such seller furnished in writing
to the Company by or on behalf of such seller specifically for use in connection
with the preparation of such Registration Statement, prospectus, amendment or
supplement; provided, however, that the obligations of such Stockholders
            -----------------                                           
hereunder shall be limited to an amount equal to the proceeds to each
Stockholder of Registrable Shares sold in connection with such registration.

          (c)  Each party entitled to indemnification under this Section 5 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; provided, that counsel for the Indemnifying
                                --------                                   
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld); and, provided, further, that the failure of any Indemnified Party to
                -----------------                                              
give notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Section 5. The Indemnified Party may participate in such
defense at such party's expense; provided, however, that the Indemnifying Party
                                 -----------------                             
shall pay such expense if representation of such Indemnified Party by the
counsel retained by the Indemnifying Party would be inappropriate due to actual
or potential differing interests between the Indemnified Party and any other
party represented by such counsel in such proceeding. No Indemnifying Party, in
the defense of any such claim or litigation shall, except with the consent of
each Indemnified Party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect of such claim or litigation, and no Indemnified Party shall
consent to entry of any judgment or settle such claim or litigation without the
prior written consent of the Indemnifying Party.
<PAGE>
 
          (d)  In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which either (i) any holder of
Registrable Shares exercising rights under this Agreement, or any controlling
person of any such holder, makes a claim for indemnification pursuant to this
Section 5 but it is judicially determined (by the entry of a final judgment or
decree by a court of competent jurisdiction and the expiration of time to appeal
or the denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 5 provides for
indemnification in such case, or (ii) contribution under the Securities Act may
be required on the part of any such selling Stockholder or any such controlling
person in circumstances for which indemnification is provided under this Section
5; then, in each such case, the Company and such Stockholder will contribute to
the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in such proportions so that such holder
is responsible for the portion represented by the percentage that the public
offering price of its Registrable Shares offered by the Registration Statement
bears to the public offering price of all securities offered by such
Registration Statement, and the Company is responsible for the remaining
portion; provided, however, that, in any such case, (A) no such holder will be
         -----------------                                                    
required to contribute any amount in excess of the proceeds to it of all
Registrable Shares sold by it pursuant to such Registration Statement, and (B)
no person or entity guilty of fraudulent misrepresentation, within the meaning
of Section 11(f) of the Securities Act, shall be entitled to contribution from
any person or entity who is not guilty of such fraudulent misrepresentation.

     6.   Information by Holder.  Each Stockholder including Registrable Shares
          ---------------------                                                
in any registration shall furnish to the Company such information regarding such
Stockholder and the distribution proposed by such Stockholder as the Company may
reasonably request in writing and as shall be required in connection with any
registration, qualification or compliance referred to in this Agreement.

     7.   "Stand-Off" Agreement.  Each Stockholder, if requested by the Company
           --------------------                                                
and the managing underwriter of an offering by the Company of Common Stock or
other securities of the Company pursuant to a Registration Statement, shall
agree not to sell publicly or otherwise transfer or dispose of any Registrable
Shares or other securities of the Company held by such Stockholder for a
specified period of time (not to exceed one hundred and eighty (180) days)
following the effective date of such Registration Statement.

     8.   Rule 144 Requirements.  After the earliest of (i) the closing of the
          ---------------------                                               
sale of securities of the Company pursuant to a Registration Statement, (ii) the
registration by the Company of a class of securities under Section 12 of the
Exchange Act, or (iii) the issuance by the Company of an offering circular
pursuant to Regulation A under the Securities Act, the Company agrees to:

          (a)  comply with the requirements of Rule 144(c) under the Securities 
Act with respect to current public information about the Company;
<PAGE>
 
          (b)  use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements); and

          (c)  furnish to any holder of Registrable Shares upon request (i) a
written statement by the Company as to its compliance with the requirements of
said Rule 144(c), and the reporting requirements of the Securities Act and the
Exchange Act (at any time after it has become subject to such reporting
requirements), (ii) a copy of the most recent annual or quarterly report of the
Company, and (iii) such other reports and documents of the Company as such
holder may reasonably request to avail itself of any similar rule or regulation
of the Commission allowing it to sell any such securities without registration.

     9.   Mergers, Etc.  The Company shall not, directly or indirectly, enter
          ------------                                                       
into any merger, consolidation or reorganization in which the Company shall not
be the surviving corporation unless the proposed surviving corporation shall,
prior to such merger, consolidation or reorganization, agree in writing to
assume the obligations of the Company under this Agreement, and for that purpose
references hereunder to "Registrable Shares" shall be deemed to be references to
the securities which the Stockholders would be entitled to receive in exchange
for Registrable Shares under any such merger, consolidation or reorganization;
provided, however, that the provisions of this Section 9 shall not apply in the
- -----------------                                                              
event of any merger, consolidation or reorganization in which the Company is not
the surviving corporation if all Stockholders are entitled to receive in
exchange for their Registrable Shares consideration consisting solely of (i)
cash, (ii) securities of the acquiring corporation which may be immediately sold
to the public without registration under the Securities Act, or (iii) securities
of the acquiring corporation which the acquiring corporation has agreed to
register within ninety (90) days of completion of the transaction for resale to
the public pursuant to the Securities Act.

     10.  Termination.  All of the Company's obligations to register Registrable
          -----------

     1.  Grant of Option.  Physicians Quality Care, Inc., a Delaware corporation
         ---------------

Agreement, this option shall be exercised by the Optionee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
Shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 5.  Such exercise
shall be effective upon receipt by the Treasurer of the Company of such written
notice together with the required payment.  The Optionee may purchase less than

option may be for any fractional share or for fewer than ten whole Shares.

         (c) Continuous Relationship with the Company or its Affiliate Required.
             -----------------------------------------------------------------  
Except as otherwise provided in this Section 4, this option may not be exercised

Affiliate (an "Eligible Optionee").

         (d) Termination of Relationship with the Company or its Affiliate.  
             -------------------------------------------------------------     
If the Optionee ceases to be an Eligible Optionee for any reason, then, except

                  -------- ----                                             
extent that the Optionee was entitled to exercise this option on the date of
such cessation. Notwithstanding the foregoing, if the Optionee, prior to the
Expiration Date, materially violates the non-competition or confidentiality
provisions of any employment contract, confidentiality and nondisclosure
agreement or other agreement between the Optionee and the Company or its
Affiliate, the right to exercise this option shall terminate immediately upon
such violation.

employment agreement with Flagship dated as of the date hereof (the "Employment

                                      -3-
<PAGE>
 
or Section 8(b) thereof prior to the Expiration Date while he or she is an
Eligible Optionee, or if the Optionee dies within thee months after the Optionee
ceases to be an Eligible Optionee (other than as the result of termination of
Optionee's employment agreement by Flagship for "Cause" pursuant to Section 8(c)
of the Employment Agreement), this option shall be exercisable, within the
period of three months following the date of such termination of the Optionee
(whether or not such exercise occurs before the Expiration Date), by the
Optionee or by the person to whom this option is transferred by will or by the
laws of descent and distribution, provided that this option shall be exercisable
                                  -------- ----                                 
only to the extent that this option was exercisable by the Optionee on the date
of his or her termination.  Except as otherwise indicated by the context, the
term "Optionee," as used in this option, shall be deemed to include the estate
of the Optionee or any person who acquires the right to exercise this option by
bequest or inheritance or otherwise by reason of the death of the Optionee.

         (f) Discharge for Cause.  If the Optionee's Employment Agreement is
             -------------------                                            
terminated by Flagship for "Cause" pursuant to Section 8(c) thereof prior to the
Expiration Date, the right to exercise this option shall terminate immediately
upon such cessation of employment.

         (g) Calculation of Fair Market Value.  On any date specified herein, 
             -------------------------------- 
the term "Fair Market Value" shall mean the amount per share of Common Stock
equal to (a) the last sale price of Common Stock on such date or, if no such
sale takes place on such date, the average of the closing bid and asked prices
thereof on such date, in each case as officially reported on the principal
national securities exchange on which Common Stock is then listed or admitted to
trading, or (b) if Common Stock is not then listed or admitted to trading on any
national securities exchange but is designated as a national market system
security by the NASD, the last trading price of Common Stock on such date, or
(c) if there shall have been no trading on such date or if Common Stock is not
so designated, the average of the closing bid and asked prices of Common Stock
on such date as shown by the NASD automated quotation system, or (d) if Common
Stock is not then listed or admitted to trading on any national exchange or
quoted in the over-the-counter market, the fair value thereof determined in good
faith by the Board of Directors of the Company as of a date which is within 15
days of the date as of which the determination is to be made.

     5.  Payment of Purchase Price; Method of Payment.  Payment of the purchase
         --------------------------------------------                          
price for the Shares shall be made (i) by delivery to the Company of cash or a
check to the order of the Company in an amount equal to the purchase price of
such Shares, (ii) by any other means which the Board of Directors determines are
consistent with the purpose of the Plan and with applicable laws and regulations
(including without limitation, the provisions of Rule 16b-3 under the Securities
Exchange Act of 1934 and Regulation T promulgated by the Federal Reserve Board),
or (iii) by any combination of such methods of payment.

     6.  Nontransferability of Option.  This option is personal and no rights
         ----------------------------                                        
granted hereunder may be transferred, assigned, pledged or hypothecated in any
way (whether by operation of law or otherwise) nor shall any such rights be
subject to execution, attachment or similar process, except that this option may
be transferred (i) by will or the laws of descent and distribution or (ii)
pursuant to a qualified domestic relations order as defined in Section 414(p) of
the Code.  Upon any attempt to transfer, assign, pledge, hypothecate or
otherwise dispose of this option or of such rights contrary to the provisions
hereof, or upon the levy of any attachment or similar process upon this option
or such rights, this option and such rights shall, at the election of the
Company, become null and void.

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

         (a) General.  The Company shall, upon payment of the option price for 
             -------

to the Optionee, provided that if any law or regulation requires the Company to
take any action with respect to such Shares before the issuance thereof, then
the date of delivery of such Shares shall be extended for the period necessary
to complete such action.

         (b) Listing Qualification, Etc.  This option shall be subject to the
             --------------------------                                      
requirement that if, at any time, counsel to the Company shall determine that
the listing, registration or qualification of the Shares subject hereto upon any
securities exchange or under any state or federal law, or the consent or
approval of any governmental or regulatory body, or that the disclosure of non-
public information or the satisfaction of any other condition is necessary as a
condition of, or in connection with, the issuance or purchase of Shares
hereunder, this option may not be exercised, in whole or in part, unless such
listing, registration, qualification, consent or approval, disclosure or
satisfaction of such other condition shall have been effected or obtained on
terms acceptable to the Board of Directors.  Nothing herein shall be deemed to
require the Company to apply for, effect or obtain such listing, registration,
qualification or disclosure, or to satisfy such other condition.

          ---------------------------------------
Plan or this option shall be construed or deemed by any person under any
circumstances to bind the Company or its Affiliate to continue the employment or
other relationship of the Optionee with the Company or its Affiliate for the
period within which this option may be exercised.

     10.  Rights as a Stockholder.  The Optionee shall have no rights as a
          -----------------------                                         
stockholder with respect to any Shares which may be purchased by exercise of
this option (including, without limitation, any rights to receive dividends or
non-cash distributions with respect to such Shares) unless and until a
certificate representing such Shares is duly issued and delivered to the
Optionee.  No adjustment shall be made for dividends or other rights for which
the record date is prior to the date such stock certificate is issued.

     11.  Adjustment Provisions.

binding and conclusive.  No fractional shares will be issued pursuant to this
option on account of any such adjustments.

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

          (a)  Representations.  The Optionee represents, warrants and 
               ---------------                                                  
covenants that:
              
               (i)   Any Shares purchased upon exercise of this option shall be
          acquired for the Optionee's account for investment only, and not with
          a view to or for the sale in connection with any distribution of the
          Shares in violation of the Securities Act of 1933 (the "Securities
          Act"), or any rule or regulation under the Securities Act.

               (ii)  The Optionee has had such opportunity as he or she has
          deemed adequate to obtain from representatives of the Company such
          information as is necessary to permit the Optionee to evaluate the
          merits and risks of his or her investment in the Company.

               (iii) The Optionee is able to bear the economic risk of holding
          such Shares acquired pursuant to the exercise of this option for an
          indefinite period.

               (iv)  The Optionee understands that (A) the Shares acquired
          pursuant to the exercise of this option will not be registered under
          the Securities Act and are "restricted securities" within the meaning
          of Rule 144 under the Securities Act; (B) such Shares cannot be sold,
          transferred or otherwise disposed of unless they are subsequently
          registered under the Securities Act or an exemption from registration
          is then available; (C) in any event, an exemption from registration
          under Rule 144 or otherwise under the Securities Act may not be
          available for at least two years and even then will not be available
          unless a public market then exists for the Common Stock, adequate
          information concerning the Company is then available to the public,
          and other terms and conditions of Rule 144 are complied with; and (D)
          there is now no registration statement on file with the Securities and
          Exchange Commission with respect to any stock of the Company and the
          Company has no obligation or current intention to register any Shares
          acquired pursuant to the exercise of this option under the Securities
          Act.

               (v)   The Optionee agrees, that, if the Company offers any of its
          Common Stock for sale pursuant to a registration statement under the
          Securities Act, the Optionee will not, without the prior written
          consent of the Company, offer, sell, contract to sell or otherwise
          dispose of,

          exercise of this option for a period of 90 days after the effective
          date of such registration statement.

By making payment upon exercise of this option, the Optionee shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 14.

          registration under the Act covering the transfer or an opinion of
          counsel, satisfactory to the issuer, that registration under the Act
          is not required."

              "The shares of stock represented by this certificate are subject

                              MANAGEMENT AGREEMENT

     This Management Agreement (this "Agreement") is entered into as of the 30th
day of August 1996 by and between Physicians Quality Care, Inc., a Delaware

          Whereas, subject to the terms and conditions of this Agreement, the
     Company desires to retain Bain to provide certain management and advisory
     services to the Company, and Bain desires to provide such services;

     Now, therefore, in consideration of the mutual covenants contained herein,
and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto, intending to be legally
bound, hereby agree as follows:

1.   Services.   Bain hereby agrees to, during the term of this Agreement
(the "Term"):

     a. provide the Company with advice in connection with the negotiation and
        consummation of agreements, contracts, documents and instruments
        necessary to provide the Company with financing from banks or other
        financial institutions or other entities on terms and conditions
        satisfactory to the Company; and

     b. provide the Company with financial, managerial and operational advice in
        connection with its day-to-day operations, including, without
        limitation:

        i.   advice with respect to the investment of funds;

        ii.  advice with respect to the development and implementation of
             strategies for improving the operating, marketing and financial

        iii. advice with respect to the development, structuring and
             implementation of strategic acquisitions and physician practice
             affiliations; and

        iv.  advice in respect of telecommunications and information system and
             accounting and administration.

2.   Payment of Fees.  The Company hereby agrees to:

        a management fee of $500,000 per annum in exchange for the services
        provided to the Company by Bain, as more fully described in Section 1 of
        this Agreement, such fee being payable by the Company quarterly in
        advance, the first such payment to be made at the closing of the first
        Equity Investment; and 

                                      -1-

     b. during the Term, allow Bain to participate in the negotiation and
        consummation of financing for the Company or any of its direct or
        indirect subsidiaries or affiliates, and pay to Bain (or an affiliate of
        Bain designated by it) a fee in connection therewith equal to one
        percent (1%) of the gross amount of such financings, such fee to be due
        and payable for the foregoing services at the closing of such financing;
        provided, however, that the foregoing fee shall not be payable in
        --------  -------

        working capital and other similar requirements; (ii) capital lease
        obligations; (iii) equipment lease financings; (iv) letters of credit;

     Each payment made pursuant to this Section 2 shall be paid by wire transfer
     of immediately available federal funds to the account specified on Schedule
     1 hereto, or to such other account(s) as Bain may specify to the Company in
     writing prior to such payment.

3.   Term. This Agreement shall continue in full force and effect, unless and
     until terminated by mutual consent of the parties, for so long as Bain (or
     any successor or permitted assign, as the case may be) continues to carry
     on the business of providing services of the type described in Section 1
     above; provided, however, that (i) this Agreement shall terminate on the
     later to occur of (a) the five year anniversary of the date hereof and (b)
     twelve (12) months after the date of a Qualified Public Offering (as

     provided further either party may terminate this Agreement following a

     and a failure to cure such breach within 30 days following written notice
     thereof; and provided further that each of (i) the obligations of the
     Company under Section 4 below, (ii) any and all accrued and unpaid

        operations hereunder or otherwise incurred in connection with the

        consultants or advisors retained by Bain, Bain Capital, Inc., the Bain
        Funds or either of the parties identified in clauses (A) and (B) arising
        in connection therewith (including but not limited to the preparation,
        negotiation and execution of this Agreement and any other agreement
        executed in connection herewith or the consummation of the other
        transactions contemplated hereby (and any and all amendments,
        modifications, restructurings and waivers, and exercises and
        preservations of rights and remedies hereunder or thereunder) and the
        operations of the Company and any of its subsidiaries), and (ii) any out
        of-pocket expenses incurred by Bain in connection with the provision of
        services hereunder or the attendance at any meeting of the board of
        directors (or any committee thereof) of the Company or any of its
        affiliates, such fees and disbursements in (i) and (ii) above not to
        exceed $100,000 per annum without the consent of the Company. 

     b. Indemnity and Liability. In consideration of the execution and delivery
        of this Agreement by Bain, the Company hereby agrees to indemnify,
        exonerate and hold each of Bain, Bain Capital, Inc. and each Bain Fund,
        and each of their respective partners, shareholders, affiliates,
        directors, officers, fiduciaries, employees and agents and each of the
        partners, shareholders, affiliates, directors, officers, fiduciaries,
        employees and agents of each of the foregoing (collectively, the
        "Indemnitees") free and harmless from and against any and all actions,
        causes of action, suits, losses, liabilities and damages, and expenses
        in connection therewith, including without limitation attorneys' fees
        and disbursements (collectively, the "Indemnified Liabilities"),
        incurred by the Indemnitees or any of them as a result of, or arising
        out of, or relating to the execution, delivery, performance, enforcement
        or existence of this Agreement, except for any such Indemnified
        Liabilities arising on account of such Indemnitee's gross negligence,
        bad faith or willful misconduct, and if and to the extent that the
        foregoing undertaking may be unenforceable for any reason, the Company
        hereby agrees to make the maximum contribution to the payment and
        satisfaction of each of the Indemnified Liabilities which is permissible
        under applicable law. None of the Indemnitees shall be liable to the
        Company or any of its affiliates, agents, advisors, representatives, or
        accountants for any act or omission suffered or taken by such Indemnitee
        that does not constitute gross negligence, bad faith or willful
        misconduct. The Indemnitees agree that none of them will enter into a
        settlement agreement for any Indemnified Liabilities without the prior
        Consent of the Company. The Company shall have the right to participate
        in any action which shall be the subject of this paragraph 4(b) at its
        own cost and expense.

5.   Assignment, etc. Neither party shall have the right to assign this
     Agreement. Bain acknowledges that its services under this Agreement are
     unique. Accordingly, any purported assignment by Bain shall be void.
     Notwithstanding the foregoing, (a) Bain may assign all or part of its
     rights and obligations hereunder to any affiliate of Bain which provides
     services similar to those called for by this Agreement which shall be
     acceptable to the Company in its reasonable discretion, in which event Bain
     shall 

                                      -3-
<PAGE>
 
     be released of all of its rights and obligations hereunder, and (b) the
     provisions hereof for the benefit of the Bain Funds shall inure to the
     benefit of their successors and assigns.

6.   Amendments and Waivers. No amendment or waiver of any term, provision or
     condition of this Agreement shall be effective, unless in writing and
     executed by each of Bain and the Company. No waiver on any one occasion
     shall extend to or effect or be construed as a waiver of any right or
     remedy on any future occasion. No course of dealing of any person nor any
     delay or omission in exercising any right or remedy shall constitute an
     amendment of this Agreement or a waiver of any right or remedy of any party
     hereto.

7.   Additional Services. Nothing contained herein shall limit the right of the
     Bain Funds, Bain or Bain Capital, Inc. to provide for consideration to any
     person, including the Company, any additional services and advice in
     connection with the sale or merger of the Company, its subsidiaries or any
     affiliates thereof or any securities of such entities.

8.   Miscellaneous.

     a. Choice of Law. This Agreement shall be governed by and construed in
        accordance with the domestic substantive laws of The Commonwealth of
        Massachusetts without giving effect to any choice or conflict of law

     b. Consent to Jurisdiction. Each of the parties agrees that all actions,
        suits or proceedings arising out of or based upon this Agreement or the
        subject matter hereof shall be brought and maintained exclusively in the

        the parties hereto by execution hereof (i) hereby irrevocably submits to
        the jurisdiction of the federal and state courts in The Commonwealth of
        Massachusetts for the purpose of any action, suit or proceeding arising
        out of or based upon this Agreement or the subject matter hereof and
        (ii) hereby waives to the extent not prohibited by applicable law, and
        agrees not to assert, by way of motion, as a defense or otherwise, in
        any such action, suit or proceeding, any claim that it is not subject
        personally to the jurisdiction of the above-named courts, that it is
        immune from extraterritorial injunctive relief or other injunctive
        relief, that its property is exempt or immune from attachment or
        execution, that any such action, suit or proceeding may not be brought
        or maintained in one of the above-named courts, that any such action,
        suit or proceeding brought or maintained in one of the above-named

        transferred to any court other than one of the above-named courts,
        should be stayed by virtue of the pendency of any other action, suit or
        proceeding in any court other than one of the above-named courts, or
        that this Agreement or the subject matter hereof may not be enforced in
        or by any of the above-named courts. Each of the parties hereto hereby
        consents to service of process in any such suit, action or 

                                      -4-
<PAGE>
 
        proceeding in any manner permitted by the laws of The Commonwealth of
        Massachusetts, agrees that service of process by registered or certified
        mail, return receipt requested, at the address specified in or pursuant
        to Section 9 is reasonably calculated to give actual notice and waives
        and agrees not to assert by way of motion, as a defense or otherwise, in
        any such action, suit or proceeding any claim that service of process
        made in accordance with Section 9 does not constitute good and
        sufficient service of process. The provisions of this Section 7(b) shall
        not restrict the ability of any party to enforce in any court any
        judgment obtained in a federal or state court of The Commonwealth of
        Massachusetts.

     c. Waiver of Jury Trial. To THE EXTENT NOT PROHIBITED BY APPLICABLE LAW
        WHICH CANNOT BE WAIVED, EACH OF THE PARTIES HERETO HEREBY WAIVES, AND
        COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT, OR
        OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY
        ISSUE, CLAIM, DEMAND, CAUSE OF ACTION, ACTION, SUIT OR PROCEEDING
        ARISING OUT OF OR BASED UPON THIS AGREEMENT OR THE SUBJECT MATTER
        HEREOF, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING AND
        WHETHER IN CONTRACT OR TORT OR OTHERWISE. Each of the parties hereto
        acknowledges that it has been informed by each other party that the
        provisions of this Section 7(c) constitute a material inducement upon
        which such party is relying and will rely in entering into this
        Agreement and the transactions contemplated hereby. Any of the parties
        hereto may file an original counterpart or a copy of this Agreement with
        any court as written evidence of the consent of each of the parties
        hereto to the waiver of its right to trial by jury.

     of the parties with respect to the subject matter hereof and supersedes any
     prior communication or agreement with respect thereto.

Landlord, for parking by its customers, employees, suppliers and visitors.
Landlord reserves the right from time to time, and at Landlord's sole
discretion, to alter or redesign the parking area, to temporarily close portions
of the parking area and/or to relocate the ingress and egress to and from the
parking area and Building provided, however, that Landlord will use reasonable
efforts to minimize interference with Tenant's use and enjoyment of the

provided that substitutions are substantially equivalent or better.  However,
with respect to any such activities within the Premises, Landlord shall act
diligently to minimize interference with Tenant's activities, so as to assure
that there will be no material interference with Tenant's use and enjoyment of
the Premises.  Landlord reserves the exclusive use of all fan rooms, electric
and telephone closets, janitor closets, freight elevator vestibules, pipes,
ducts, conduits, wires and appurtenant fixtures located within the Premises

          (a) Tenant agrees to pay to Landlord, or as directed by Landlord,
without offset, abatement (except as provided in Section 12.1), deduction or
demand, Basic Rent and Tenant's Electrical Charge.  Basic Rent and Tenant's
Electrical Charge shall be payable in equal monthly installments, in advance, on

Landlord's Address, or at such other place as Landlord shall from time to time
designate by notice.

          (b) Basic Rent and Tenant's Electrical Charge for any partial month
shall be prorated on a daily basis, and if the Initial Term commences on a day
other than the first day of a calendar month, the first payment which Tenant
shall make to Landlord shall be payable on the Commencement Date and shall be
equal to a proportionate part of the monthly installment of Basic Rent and
Tenant's Electrical Charge for the partial month from the Commencement Date to
the last day of the month in which the Commencement Date occurs plus the
installment of Tenant's Electrical Charge and Basic Rent for the succeeding
calendar month.  In addition to any charges pursuant to Section 14.16, Tenant
shall pay a late charge equal to 5% of the amount of any Basic Rent payment or
Escalation Charge not paid when due (unless such late charge is prohibited by
any applicable law).

                                  ARTICLE  IV
                                 TERM OF LEASE

     4.1  COMMENCEMENT DATE.  The Commencement Date shall be the date on which
Landlord tenders the Premises to Tenant for Tenant's possession; provided,
however, that if the date of tender is earlier than December 1, 1995, then the
Commencement Date shall be the earlier of (a) the date on which Tenant accepts
possession of the Premises and (b) December 1, 1995.  At such time as the
Commencement Date has occurred, Landlord and Tenant shall enter into a written
instrument, confirming the exact date of the Commencement Date.

     If Landlord shall be unable to give possession of the Premises on the
Anticipated Term Commencement Date because the previous occupant of the Premises
has not vacated the Premises, Landlord shall not be subject to any liability for
failure to give possession on said date, nor shall such failure affect the
validity of this Lease.

     4.2  INITIAL CONDITION OF THE PREMISES.  Tenant expressly agrees that it
will accept possession of the Premises in a totally "as-is" condition; that
Landlord has made no representation or warranty concerning the fitness of the
Premises for Tenant's intended use of the Premises; and that Landlord shall have
no obligation to alter, renovate or improve the Premises in any way.

     4.4  [INTENTIONALLY OMITTED.]

     4.5  GENERAL PROVISIONS APPLICABLE TO CONSTRUCTION.  All of Tenant's
alterations, additions and installation of furnishings shall be coordinated with
any work being performed by Landlord and in such manner as to maintain
harmonious labor relations and not damage the Property or interfere with
Building construction or operation and, except for installation of furnishings,
shall, at Landlord's option, be performed by Landlord's general contractor or by
contractors or workmen first approved by Landlord.  If Landlord shall require
that Tenant retain Landlord's contractor, Landlord's contractor shall provide
its services at costs reasonably comparable to the charges imposed by other
reputable contractors in the Metropolitan Boston area; and Landlord shall
provide supervisory services (for which Tenant shall pay to Landlord a
reasonable supervisory fee).  If Landlord shall not require that Tenant retain
Landlord's contractor, Landlord shall not unreasonably withhold or delay its
approval of contractors and workmen chosen by Tenant.  Except for work by
Landlord's general contractor, Tenant before its work is started shall: secure
all licenses and permits necessary therefor; deliver to Landlord a statement of
the names of all of its contractors and subcontractors and the estimated cost of
all labor and material to be furnished by them; and cause each contractor to
carry workmen s compensation insurance in statutory amounts covering all of the
contractor's and subcontractor's employees and comprehensive public liability
insurance and property damage insurance with such limits as Landlord may
reasonably require but in no event less than, with respect to public liability
insurance, the amount specified in Section 1.2 (all such insurance to be written
in companies approved by Landlord and insuring Landlord and Tenant as well as
the contractors), and to deliver to Landlord certificates of all such insurance.
Tenant agrees to pay promptly when due the entire cost of any work done on the
Premises by Tenant, its agents, employees, or independent contractors, and not
to cause or permit any liens for labor or materials performed or furnished in
connection therewith to attach to the Premises or the Property and immediately
to discharge any such liens which may so attach and, at the request of Landlord,
to deliver to Landlord security satisfactory to Landlord against liens arising
out of the furnishing of such labor and materials.  Upon completion of any work
done on the Premises by Tenant, its agents, employees or independent
contractors, Tenant shall promptly deliver to Landlord original lien releases
and waivers executed by each contractor, subcontractor, supplier, materialman,
architect, engineer or other party which furnished labor, materials or other
services in connection with such work and pursuant to which all liens, claims
and other rights of such party with respect to labor, material or services
furnished in connection with such work are unconditionally released and waived.
No material or equipment shall be incorporated in the Premises by Tenant which
is subject to any lien, charge, mortgage or other encumbrance of any kind
whatsoever, or subject to any conditional sale, or other similar or dissimilar
title retention agreement.  If Tenant fails to comply with any of the foregoing
obligations, then, in addition to all other rights and remedies hereunder,
Landlord may by notice to Tenant require Tenant to cease the performance of any
alteration, addition or installation until the offending condition has been
remedied.

     All construction work required or permitted by this Lease shall be done in
a good and workmanlike manner and in compliance with all applicable laws and
lawful ordinances, regulations and orders of governmental authority and insurers
of the Property.  Each party may inspect the work of the other at reasonable
times (and without causing interference with 

                                      -6-
<PAGE>
 
on-going construction activities) and shall promptly give notice of observed
defects. Each party authorizes the other to rely, in connection with design and
construction, upon approval and other actions on the party's behalf by the
Construction Representative of the party, if any, named in Article I or any
person named in substitution or addition by notice to the party relying.

     The foregoing provisions of this Section 4.5 shall apply from and after the
execution of this Lease, and thereafter for so long as this Lease shall remain
in force and effect.

     4.6  CHANGES IN THE OFFICE PARK.  Landlord expressly reserves the right to
change the layout, design and plans for the Office Park and the Common Property
at any time and to add to or reduce the size of the Land; provided that no
reduction in the size of the Land may result in a permanent material adverse
effect upon the Building or the parking areas, streets or sidewalks serving the
Building.  Landlord hereby expressly reserves the right to dedicate the roads
within the Office Park for public use.

                                  ARTICLE  V
                               REAL ESTATE TAXES

     5.1  PAYMENTS ON ACCOUNT OF REAL ESTATE TAXES.

          (a) For the purpose of this Article, the term "Tax Year" shall mean
the twelve-month period commencing on the July 1 immediately preceding the
Commencement Date and each twelve-month period thereafter occurring wholly or
partially during the Term, and the term "Taxes" shall mean all taxes and special
assessments of every kind and nature assessed by any governmental authority upon
or against the Land and/or the Building and/or the Property or any part thereof,
or payments in lieu thereof, or which Landlord shall become obligated to pay
because of or in connection with the ownership, leasing and operation of the
Land and/or the Building and/or the Property and reasonable expenses of any
proceedings for abatement of Taxes.  "Taxes" shall also include, if any, such
portion of any taxes and special assessments assessed against the remainder of
the Office Park as may be allocated to Landlord as owner of the Land and/or the
Building and/or the Property, pursuant to any joint operating agreement or other
similar arrangement between Landlord and the owner(s) of the remaining portions
of the Office Park.  The amount of special taxes or special assessments to be
included shall be limited to the amount of the installment (plus any interest,
other than penalty interest, payable thereon) of such special tax or special
assessment required to be paid during the year in respect of which such taxes
are being determined.  There shall be excluded from Taxes (i) any federal, state
or local income, profit, franchise, privilege, capital levy, excise,
inheritance, estate, succession, gift, deed, conveyance or transfer taxes, and
(ii) so long as Tenant has satisfied its obligations under this Article V on a
timely basis, any penalties or interest resulting from the late payment of
Taxes: provided, however, that if at any time during the Term the present system
of ad valorem tax on real property shall be changed so that, in lieu of the
whole or any part of the ad valorem tax on real property, there shall be
assessed to Landlord a capital levy or other tax on the gross rents received
with respect to the Property, or a federal, state, county, municipal, or other
local income, franchise, excise or similar tax, assessment, levy or charge
(distinct from any now in effect in the jurisdiction in which the Property is
located) measured by or based, 

                                      -7-
<PAGE>
 
in whole or in part, upon any such gross rents, then any and all of such capital
levy or taxes shall be included within the term "Taxes", but only to the extent
that the same would be payable if the Property were the only property of
Landlord.

          (b) In the event that, for any reason, Taxes shall be greater during
any Tax Year than the Tax Base, Tenant shall pay to Landlord, as an Escalation
Charge, an amount (the "Tax Excess") equal to the excess of Taxes over the Tax
Base multiplied by Tenant's Tax and Operating Percentage, such amount to be
apportioned for any fraction of a Tax Year in which the Commencement Date falls
or the Term ends.,

          (c) Payment of Tenant's Tax Excess shall be made to Landlord within
twenty (20) days from the date Landlord shall give written notice to Tenant
that, based upon a bill received for Taxes (or partial Taxes), or other form of
notice received from any governmental authority responsible for Taxes, there is
due from Tenant any Tax Excess (which collection notice shall set forth the
manner of computation of any Tax Excess due from Tenant).  At Landlord's
election, simultaneously with Tenant's monthly payments of Basic Rent, Tenant
shall remit to Landlord one-twelfth of Landlord's estimate of the Tax Excess for
the then-current Tax Year.  If the total of such monthly remittances is greater
than the Tax Excess for such Tax Year, Landlord shall credit the difference
against the next installment of Tax Excess due to Landlord hereunder (except,
that, upon Tenant's request, and so long as Tenant is not then in default in the
performance of its obligations hereunder, Landlord shall pay such excess
directly to Tenant, in cash); and if the total of such remittances is less than
the Tax Excess for such Tax Year, Tenant shall pay the difference at the time
any Tax Excess becomes due and payable as hereinabove provided.

          (d) If Landlord shall receive any refund of Taxes as to which Tenant
has paid Tax Excess, Tenant shall be entitled to receive a refund from Landlord
in an amount equal to the smaller of (i) the amount of Tax Excess paid by Tenant
with respect to the Tax Year as to which the refund was obtained by Landlord and
(ii) Tenant's Tax and Operating Percentage multiplied by the amount (if any) by
which the amount of the refund received by Landlord exceeds the costs and
expenses incurred by Landlord in obtaining such refund.

     5.2  ALTERNATE TAXES.  If some method of taxation shall replace the current
method of assessment of real estate taxes, or the type thereof, Tenant agrees
that Tenant shall pay an equitable share of the same computed in a fashion
consistent with the method of computation herein provided, to the end that
Tenant's share thereof shall be, to the maximum extent practicable, comparable
to that which Tenant would bear under the foregoing provisions.

     5.3  PERSONAL PROPERTY TAXES.  Tenant shall pay, promptly when due, all
taxes which may be imposed upon personal property (including, without
limitation, fixtures and equipment) in the Premises to whomever assessed.

                              OPERATING EXPENSES

     6.1  DEFINITIONS.  For the purpose of this Article, the following terms
shall have the following respective meanings:

          Operating Year:  Each calendar year in which any part of the Term
          shall fall.

          Operating Expenses:  All costs and expenses incurred with respect to

     respect to the remainder of the Office Park and allocated to Landlord as
     owner of the Land and/or the Building and/or the Property), including
     without limiting the generality of the foregoing:

                    (a) all salaries, wages, fringe benefits, payroll taxes and
          workmen's compensation insurance premiums related thereto with respect
          to any employees of Landlord engaged in security, operation,
          management and maintenance of the Property and the Common Property,
          exclusive, however, of the allocable share of all management personnel
          expenses not related to the operation, maintenance or upkeep of the
          Property and the Common Property;

                    (b) all utilities and other costs related to provision of
          heat (including oil and/or gas), air-conditioning, lighting, and water
          (including sewer charges) and other utilities to the Property and the
          Common Property;

                    (c) all costs, including, without limitation, material and
          equipment costs, for cleaning, maintenance, replacement, repair and
          upkeep of the Property (including without limitation window cleaning
          of the Building) and/or the Common Property, and of all parking areas,
          roads and landscaping located on the Property and the Common Property;

                    (d) all costs of any insurance carried by Landlord relating

          condition (including, but not limited to, snow removal, security,
          operation and repair of heating and air-conditioning equipment,
          elevators, and any other common Building equipment or system), as well
          as the cost of all repairs and replacements other than repairs for
          which Landlord has received full reimbursement from contractors, other
          tenants of the Building or others;

                                      -9-
<PAGE>
 
                    (f) all legal, accounting, management and other fees and
          charges directly related to the operation, management and
          administration of the Property and the Common Property (including any
          management fee charged by Landlord for its services in connection with
          the operation, management and administration of the Property);

                    (g) all costs for electricity supplied to the Property
          and/or the Common Property after deducting (i) Tenant's Electrical
          Charge paid by Tenant for such period and (ii) all payments of
          electricity charges from other tenants in the Property for such period
          which are separately stated in such other tenant leases as "Tenant's
          Electrical Charge". The cost of electricity supplied to Tenant and to
          other tenants of the Building which is separately metered shall not be
          included in Operating Expenses (but, in such case, the Operating
          Expense Base shall be reduced as and to the extent such Operating
          Expense includes sums attributable to the electricity being metered);

                    (h) all costs of disposal of refuse from the Property and/or
          the Common Property;

                    (i) all license, permit and inspection fees relating to the

                    (j) all capital expenses incurred for the purpose of
          reducing Operating Expenses (even if no such reduction in fact
          results) or required to be made by federal, state or local regulation
          or ordinance not in effect as of the Commencement Date;

                    (k) if during the Term, Landlord shall add or replace a
          capital item other than as provided in Item (j), there shall be
          included in Operating Expenses for that and each succeeding calendar
          year the amount of the annual charge-off (determined as hereinafter
          provided) of such capital expenditure together with interest at an
          annual rate equal to 2% over the "prime rate" of Bank of Boston in
          effect at the time of making such capital expenditure (less insurance
          or other proceeds, if any, collected by Landlord by reason of damage
          to, or destruction of' any capital item so replaced). (Annual charge-
          off shall be determined by dividing the original cost of a capital
          item or a capital expenditure made during the Term by the number of
          years of useful life of the item acquired, and the useful life shall
          be determined by Landlord's accountants in accordance with generally
          accepted accounting principles and practices in effect at the time of
          acquisition of the capital item.); and

                    (1) all costs and fees payable under service and management
          contracts relating to matters referred to in Items (a) through (i)
          hereof.

                                      -10-
<PAGE>
 
          There shall not be included in Operating Expenses:

                    (i) Painting, decoration or other work which Landlord
          performs for any other tenant or prospective tenant of the Building
          other than painting, decoration or other work which is standard for
          the Building and performed for tenants subsequent to their initial
          occupancy;

                    (ii) Leasing commissions and expenses of procuring tenants,
          including lease concessions and lease takeover obligations;

                    (iii)  Legal fees incurred in connection with the execution
          or enforcement of any other lease concerning premises in the Building;

                    (iv) Depreciation;

                    (v) Interest on and amortization of debt;

                    (vi) Wages or salaries of employees over the rank of
          building manager;

                    (vii)  Taxes; and

                    (viii)  Rents payable under any ground lease affecting the
          Property.

     If, during any portion of the Operating Year for which Operating Expenses
are being computed, less than 95% of Building Rentable Area was occupied by
tenants, actual Operating Expenses incurred shall be reasonably extrapolated by
Landlord on an item by item basis to the estimated Operating Expenses that would
have been incurred if the Building were 95% occupied for such year, and such
extrapolated amount shall, for the purpose hereof be deemed to be Operating
Expenses for such Year.

     Tenant acknowledges that Landlord's formula for sharing of Operating
Expenses stated in this Lease is based on the assumption that Landlord will be
providing substantially similar services to all tenants in the Property from
year to year.  If this assumption is not, in fact, correct (that is, if Landlord
is not furnishing any particular work or service (the cost of which, if
performed by Landlord, would be included in Operating Expenses) to a tenant who
has undertaken to perform such work or service in lieu of the performance
thereof by Landlord), Operating Expenses shall be deemed, for purposes of this
paragraph, to be increased by an amount equal to the additional Operating
Expenses which would reasonably have been incurred during such period by
Landlord if it had, at its own expense, furnished such work or service to such
tenant.

     6.2  TENANT'S PAYMENTS.  In the event that Operating Expenses for any
Operating Year shall exceed the Operating Expense Base, Tenant shall pay to
Landlord, as an Escalation Charge, an amount (the "Operating Expense Excess")
equal to Tenant's Tax and 

                                      -11-
<PAGE>
 
Operating Percentage multiplied by the sum of (i) 100% of such increase in
Operating Expenses related to the Property plus (ii) the percentage of any such
increase in Operating Expenses related to the Common Property which Landlord
fairly allocates to the Property, such amount to be apportioned for any
Operating Year in which the Commencement Date falls or the Term ends.

     Payment of any Operating Expense Excess shall be made to Landlord within
twenty (20) days from the date Landlord shall furnish to Tenant an itemized
statement of Tenant's share of any such excess, prepared, allocated and computed
in accordance with generally accepted accounting principles.  At Landlord's
election, simultaneously with Tenant's monthly payments of Basic Rent, Tenant
shall remit to Landlord one-twelfth (1/12th) of Landlord's estimate of the
Operating Expense Excess for the then-current Operating Year.  If the total of
such monthly remittances is greater than the Operating Expense Excess for such
year, Landlord shall credit any such excess payments against the next
installment of Operating Expense Excess due to Landlord hereunder (except that,
upon Tenant's request, and so long as Tenant is not then in default in the
performance of its obligations hereunder, Landlord shall pay such excess
directly to Tenant, in cash); and if the total of such remittances is less than
the Operating Expense Excess for such year, Tenant shall pay the difference to
Landlord at the time the first monthly installment of Operating Expense Excess
with respect to the next succeeding Operating Year becomes due and payable as
hereinabove provided.

                                 ARTICLE  VII
                                USE OF PREMISES

     7.1  PERMITTED USES.

          (a) Tenant agrees that the Premises shall be used and occupied by
Tenant only for the Permitted Uses and for no other purposes.

          (b) Tenant agrees to conform to the following provisions during the
Term:

               (i)    Tenant shall cause all freight and other property to be
          delivered to or removed from the Building and the Premises in
          accordance with reasonable rules and regulations established by
          Landlord therefor.  Tenant shall not receive or ship articles of any
          kind except through loading and receiving facilities, if any, provided
          for those purposes by Landlord; and

               (ii)   Tenant will not place on the exterior of the Premises
          (including both interior and exterior surfaces of windows and
          door(s)), or on any part of the Land or Building outside the Premises,
          any sign, symbol, advertisement or the like visible to public view
          outside of the Premises.  Landlord will not unreasonably withhold
          consent for signs or lettering on the entry doors to the Premises
          provided such signs conform to Building standards adopted by Landlord
          and Tenant has submitted to Landlord a plan or sketch of the sign to
          be placed on such entry doors.  Landlord agrees, however, to maintain
          a 

                                      -12-
<PAGE>
 
          tenant directory in the lobby of the Building in which will be
          placed Tenant's name and the location of the Premises in the Building;
          and

               (iii)  Tenant shall not perform any act or carry on any practice
          which may injure the Premises, or any other part of the Property or
          the Office Park, or cause any offensive odors or loud noise or
          constitute a nuisance or a menace to any other tenant or tenants or
          other persons in the Building or the Office Park.  Tenant shall not
          overload or otherwise misuse the plumbing, electrical and other
          utilities systems serving the Premises and the Building. Tenant shall
          not use or devote the Premises or any part thereof for any use which
          is inconsistent with the maintenance of the Building as an office
          building of first class quality in maintenance, use and occupancy, or
          which is improper, offensive, contrary to law or ordinance or liable
          to render necessary any alteration or addition to the Building; and

               (iv)   Tenant shall not operate any cooking apparatus (except for
          coffee making equipment, a microwave oven and a refrigerator), or
          locate any vending machines in the Premises without Landlord's prior
          written consent; and

               (v)    Tenant shall continuously, throughout the Term of this
          Lease, occupy the Premises for the Permitted Uses; and

               (vi)   Tenant will comply with all laws, ordinances, rules and
          regulations of governmental authorities and recommendations of the
          Fire Underwriters Rating Bureau or any similar entity with respect to
          the condition, use or occupancy of the Premises and the use or
          occupancy of the Building; and

               (vii)  Tenant shall not obstruct in any manner any portion of the
          Building not hereby leased or of the Property or the Common Property
          used by Tenant in common with others.

     7.2  INSTALLATIONS AND ALTERATIONS BY TENANT.

          (a) Tenant shall make no alterations, additions (including, for the
purposes hereof, wall-to-wall carpeting), or improvements (including Tenant's
initial improvements) in or to the Premises without Landlord's prior written
consent (Landlord agreeing hereby that such consent shall not be unreasonably
withheld or delayed with respect to any proposed alteration or addition which
will not affect (i) the structural elements or utilities systems of the
Building, (ii) the exterior appearance of the Building or (iii) the appearance
of any common area of the Building or the Office Park).  Any such alterations,
additions or improvements shall (i) be performed in a good and workmanlike
manner and in compliance with Building standards, the applicable provisions of
Article IV, and all applicable laws (Without limitation, if, because of
alterations, additions or improvements undertaken (or proposed to be undertaken)
by or on behalf of Tenant, applicable laws require additional alterations,
additions or improvements to the Premises or the Building which would not have

                                      -13-
<PAGE>
 
been required but for Tenant's additions, etc.  (or proposed additions, etc.),
Tenant shall be obligated, at its sole cost and expense, to undertake and
complete all such additional alterations, additions or improvements.), (ii) be
made only by Landlord's contractor or by contractors or mechanics approved by
Landlord (all as provided in subsection 4.3(d), above), (iii) be made at
Tenant's sole expense and at such times as Landlord may designate, and (iv)
become part of the Premises and the property of Landlord.  Tenant agrees not to
employ or permit the use of any labor or otherwise take any action which might
result in a labor dispute involving personnel providing services, labor or
material in the Building or the Office Park pursuant to arrangements made by
Landlord or Landlord's contractor.  Furthermore, Tenant agrees that it will not
permit any contractors or other persons retained by Tenant to make alterations,
additions or improvements on the Premises to commence their activities until
such time as Landlord has received Certificates of Insurance confirming that
such persons maintain public liability, automobile liability, workmen's
compensation and other insurance required by Landlord, in amounts satisfactory
to Landlord.

          (b) All articles of personal property and all business fixtures,
machinery, equipment and furniture owned or installed by Tenant solely at its
expense in the Premises ("Tenant's Removable Property") shall remain the
property of Tenant and may be removed by Tenant at any time prior to the
expiration of the Term, provided that Tenant, at its expense, shall repair, to
the satisfaction of Landlord, any damage to the Property caused by such removal.

          (c) Notice is hereby given that Landlord shall not be liable for any
labor or materials furnished or to be furnished to Tenant upon credit, and that
no mechanic's or other lien for any such labor or materials shall attach to or
affect the reversion or other estate or interest of Landlord in and to the
Premises.  Whenever and as often as any mechanic's lien shall have been filed
against the Property based upon any act or interest of Tenant or of anyone
claiming through Tenant, Tenant shall forthwith take such action by bonding,
deposit or payment as will remove or satisfy the lien.

                                 ARTICLE  VIII
                           ASSIGNMENT AND SUBLETTING

     8.1  PROHIBITION.

          (a) Subject to the remaining provisions of this subsection (a), Tenant
covenants and agrees that neither this Lease nor the term and estate hereby
granted, nor any interest herein or therein, will be assigned, mortgaged,
pledged, encumbered or otherwise transferred, and that neither the Premises nor
any part thereof will be encumbered in any manner by reason of any act or
omission on the part of Tenant, or used or occupied or permitted to be used or
occupied by anyone other than Tenant, or for any use or purpose other than a
Permitted Use, or be sublet (which term, without limitation, shall include
granting of concessions, licenses and the like) in whole or in part, without in
each case having first obtained the express written consent of Landlord.  A
transfer or assignment of 50% (computed on a cumulative aggregate basis) or more
of the stock, equity or other indicia of ownership of Tenant shall be deemed to
constitute an assignment in breach of this Section 8.1; provided, however, that
the sale of corporate treasury stock in order to increase the 

                                      -14-
<PAGE>
 
capital of Tenant shall not be restricted. The foregoing restrictions shall not
be applicable to an assignment of this Lease or a subletting of the Premises by
Tenant to a subsidiary wholly-owned by Tenant or to a controlling corporation,
the stock of which is wholly-owned by the stockholders of Tenant. It shall be a
condition of the validity of any assignment, whether with the consent of
Landlord or to a subsidiary or controlling corporation, that the assignee agrees
directly with Landlord, by written instrument in form satisfactory to Landlord,
to be bound by all the obligations of Tenant hereunder including, without
limitation, the covenant against further assignment and subletting. No
assignment or subletting shall relieve Tenant from its obligations hereunder and
Tenant shall remain fully and primarily liable therefor.

     Landlord agrees that its consent to a proposed assignment or sublease shall
not be unreasonably withheld or delayed, and Tenant agrees to provide to
Landlord such information as Landlord may reasonably require in order to reach
an informed decision. Without limitation, Landlord shall not be deemed to be
unreasonable in withholding its consent to a proposed assignment or sublease
unless each of the following criteria has been satisfied: (i) the proposed
assignee or subtenant is of good reputation and character and is of sound
financial condition, (ii) the proposed assignee or subtenant is not otherwise a
tenant of the Office Park, (iii) the proposed assignee or subtenant will use the
Premises solely for the Permitted Uses, (iv) the proposed assignee or subtenant
does not intend to use the Premises for a "Prohibited Activity" (as hereinafter
defined), (v) the intended use of the Premises by the proposed assignee or
subtenant is consistent with the maintenance of the Building as a first-class
office building, and will not interfere with the business activities of other
occupants of the Office Park, and (vi) the rental and other economic terms of
the proposed assignment or sublease are not inconsistent with or deleterious to
the economic interests of Landlord as owner of the Building.  (Without
limitation, Tenant shall not advertise or otherwise offer any portion (or all)
of the Premises at a rental rate which is lower than the rental rate then being
quoted by Landlord for equivalent space in the Building.)

     For the purposes of the immediately preceding paragraph, a "Prohibited
Activity" is a use which will, in Landlord's reasonable judgment, (i) introduce
undue amounts of public traffic in the Building (in excess of average traffic
which Landlord reasonably believes is generated by other tenants in the
Building), or (ii) place a strain on the existing plumbing, electrical and
mechanical systems of the Building or (iii) generate unusually high densities of
employees or invitees per square foot of rentable space.

          (b) If this Lease be assigned, or if the Premises or any part thereof
be sublet or occupied by anyone other than Tenant, Landlord may, whether or not
it has consented to any such assignment, subletting or occupancy, at any, time
and from time to time collect rent and other charges from the assignee,
subtenant or occupant, and apply the net amount collected to the rent and other
charges herein reserved, but no such assignment, subletting, occupancy or
collection shall be deemed a waiver of any breach of Section 8.1 (a), or the
acceptance of the assignee, subtenant or occupant as a tenant or a release of
Tenant from the further performance by Tenant of its obligations hereunder.  In
the event that Basic Rent and other charges payable to Tenant under any
assignment or sublease exceed Basic Rent and other charges payable hereunder,
Basic Rent hereunder shall automatically be deemed to be increased by 75% of the
amount of such excess.  (If only a portion of the

                                      -15-
<PAGE>
 
Premises is subleased, determination of any excess shall be computed by
allocating Basic Rent and other charges hereunder on a per square foot basis,
between the portion of the Premises which is subject to the sublease and the
remainder of the Premises.) The consent by Landlord to an assignment or
subletting shall in no way be construed to relieve Tenant or any successor from
obtaining the express written consent of Landlord to any further assignment or
subletting. No assignment or subletting and no use of the Premises by a
subsidiary wholly-owned by Tenant or controlling corporation of Tenant shall
affect the Permitted Uses.

          (c) In the event of any request by Tenant for any consent to a
proposed assignment or sublease, Landlord shall have the option instead to
terminate this Lease.  In the case of a proposed sublease concerning only a
portion of the Premises, at Landlord's option, such termination shall apply only
to that portion of the Premises which is intended to be the subject of the
sublease.  In such event, Basic Rent and other charges hereunder shall be
reduced proportionately, to take account of the reduction in the size of the
Premises which will be occupied by Tenant following such termination.
Furthermore, in the case of a sublease which is intended to apply to only a
portion of the Term, at Landlord's option, this Lease shall be terminated only
for the period of the proposed sublease, and shall be reinstated upon the
expiration of the term of the proposed sublease.  Upon any termination, as
provided above, the Premises (or the portion of the Premises to which the
termination relates) shall be delivered to Landlord in the condition in which
the Premises are required to be delivered to Landlord upon the expiration of the
Term as provided herein.  Following any such termination, Landlord shall be
entitled to enter into any lease or occupancy arrangement concerning the
Premises (or portion of the Premises, as the case may be) with any party,
including, without limitation, the assignee or subtenant proposed by Tenant.

             RESPONSIBILITY FOR REPAIRS AND CONDITION OF PREMISES;
                     SERVICES TO BE FURNISHED BY LANDLORD

     9.1  LANDLORD REPAIRS.  Except as otherwise provided in this Lease,
Landlord agrees to make such repairs to the roof exterior walls, floor slabs,
common areas and common electrical, heating, air conditioning and other common
mechanical systems and facilities of the Building as may be necessary to keep
them in serviceable condition, all insofar only as they affect the Premises,
except that Landlord shall in no event be responsible to Tenant for the
condition of glass in and about the Premises or the doors leading to the
Premises, or for any condition in the Premises or the Building caused by any act
or neglect of Tenant, its invitees or contractors.  Landlord shall also perform
snow removal and resurfacing, repairs and replacements to the surface parking
areas and sidewalks of the Property.  Landlord shall not be responsible to make
any improvements or repairs to the Building, the Land or the Office Park other
than as expressly in this Section 9.1 provided, unless expressly provided
otherwise in this Lease.

                                      -16-
<PAGE>
 
     9.2  TENANT'S AGREEMENT.

          (a) Tenant will keep neat and clean and maintain in good order,
condition and repair the Premises and every part thereof excepting only those
repairs for which Landlord is responsible under the terms of this Lease,
reasonable wear and tear of the Premises, and damage by fire or other casualty
and as a consequence of the exercise of the power of eminent domain excepted;
and shall surrender the Premises, at the end of the Term, in such condition.
Without limitation, Tenant shall maintain and use the Premises in accordance
with all directions, rules and regulations of all governmental agencies having
jurisdiction, and shall, at Tenant's own expense, obtain all permits, licenses
and the like required by applicable law.  Tenant shall be responsible for the
cost of repairs which may be made necessary by reason of damage to common areas
in the Building and the parking areas, sidewalks, paved areas, landscaping,
lighting and other facilities on the Land or in the Office Park by Tenant,
Tenant's independent contractors, or Tenant's invitees.

          (b) If repairs are required to be made by Tenant pursuant to the terms
hereof Landlord may demand that Tenant make the same forthwith, and if Tenant
refuses or neglects to commence such repairs and complete the same with
reasonable dispatch, after such demand, Landlord may (but shall not be required
to do so) make or cause such repairs to be made and shall not be responsible to
Tenant for any loss or damage that may accrue to Tenant's stock or business by
reason thereof.  In the case of emergency (that is, any condition which, if not
remedied promptly, would result in additional damage or risk of damage to
persons or property), Landlord shall be permitted to act immediately, without
the requirement of demand or notice to Tenant.  If Landlord makes or causes such
repairs to be made, Tenant agrees that Tenant shall forthwith, on demand, pay to
Landlord the cost thereof with interest thereon at the Default Rate, as an
additional charge.

     9.3  FLOOR LOAD - HEAVY MACHINERY.

          (a) Tenant shall not place a load upon any floor in the Premises
exceeding 50 pounds (live load) per square foot of usable floor area of the
Premises.  Landlord reserves the right to prescribe the position of all heavy
business machines and mechanical equipment, including safes, which shall be
placed so as to distribute the weight thereof.  Business machines and mechanical
equipment shall be placed and maintained by Tenant at Tenant's expense in
settings sufficient, in Landlord's judgement, to absorb and prevent vibration,
noise and annoyance.  Tenant shall not move any safe, heavy machinery, heavy
equipment, freight, furniture, bulky matter or fixtures into or out of the
Building without Landlord's prior consent, which consent may include a
requirement to provide insurance in such amounts as Landlord may deem
reasonable.  Tenant shall protect all elevators, sidewalks and other areas of
the Property from possible damage prior to moving any such items and shall
comply with all requirements of Landlord in connection therewith.

          (b) If any such safe, machinery, equipment, freight, bulky matter or
fixture requires special handling, Tenant agrees to employ only persons holding
a Master Rigger's License to do such work, and all work in connection therewith
shall comply with applicable laws and regulations.  Any such moving shall be at
the sole risk and hazard of Tenant, and 

                                      -17-
<PAGE>
 
Tenant will exonerate, indemnify and save Landlord harmless against and from any
liability, loss, injury, claim or suit resulting directly or indirectly from
such moving.

     9.4  BUILDING SERVICES.

          (a) Landlord shall, on Business Days (except Saturdays) from 8:00 a.m.
to 6:00 p.m.  (and on Saturdays from 9:00 a.m.  to 1:00 p.m.), furnish heating
and cooling as normal seasonal changes may require to provide reasonably
comfortable space temperature and ventilation for occupants of the Premises
under normal business operation at an occupancy of not more than one person per
150 square feet of usable floor space.  If Tenant shall require air
conditioning, heating or ventilation outside the hours and days above specified,
Landlord shall furnish such service and Tenant shall pay to Landlord therefor
such charges as may from time to time be in effect.  In the event Tenant
introduces into the Premises personnel or equipment which overloads the capacity
of the Building system or in any other way interferes with the system's ability
to perform adequately its proper functions, or which affects the temperature
otherwise maintained by the air conditioning system, supplementary systems may,
if and as needed, at Landlord's option, be provided by Landlord, at Tenant's
expense.

          (b)  Landlord shall also provide:

               (i)   Hot water for lavatory purposes and cold water (at
          temperatures supplied by the utility service supplying same) for
          drinking, lavatory and toilet purposes.  If Tenant uses water for any
          purposes other than for ordinary lavatory and drinking purposes,
          Landlord may assess a reasonable charge for the additional water so
          used, or install a water meter and thereby measure Tenant's water
          consumption for all purposes.  In the latter event, Tenant shall pay
          the cost of the meter and the cost of installation thereof and shall
          keep such meter and equipment in good working order and repair.
          Tenant agrees to pay for water consumed, as shown on such meter,
          together with the sewer charge based on such meter charges, as and
          when bills are rendered, and in the event of any default in making
          such payment Landlord may pay such charges and collect the same from
          Tenant as an additional charge.

               (ii)  Cleaning and janitorial services to the Premises, provided
          the same are kept in order by Tenant, in accordance with the cleaning
          standards set forth in Exhibit E attached hereto.

               (iii) Passenger elevator service from the existing passenger
          elevator system, for use by Tenant in common with Landlord and other
          tenants of the Building.

     9.5  ELECTRICITY.

          (a) Landlord, in its sole discretion, will either (i) furnish
electricity to the Premises sufficient to operate normal lighting and business
machines approved by Landlord (exclusive, however, of Tenant's electrical needs
for computers and similar equipment having 

                                      -18-
<PAGE>
 
special power or environmental requirements), charging Tenant's Electrical
Charge for such service, to be paid by Tenant in equal monthly installments on
the same day in each month that rental payments are due and payable hereunder
(but in no event shall Landlord be obligated to furnish electricity to supply a
requirement in excess of 3.0 watts per square foot of the usable area of the
Premises), or (ii) elect, at any time during the Term, to cause electricity
furnished to the Premises to be separately metered, in which event all charges
for electricity consumed on the Premises will be billed directly to, and paid
for by, Tenant. The cost of any such electrical meter as well as the cost of
installation, repair and replacement shall be borne by Tenant, who shall
reimburse Landlord for the cost thereof within 30 days after receipt of written
demand therefor.

          (b) Whether or not Landlord is furnishing electricity to Tenant, if
Tenant shall require electricity in excess of the quantity which is to be
furnished as provided in Section 9.5(a), Tenant shall, upon demand, reimburse
Landlord for the cost of such excess electricity.  Further, if (i) in Landlord's
judgement, Landlord's facilities are inadequate for such excess requirements, or
(ii) such excess shall result in an additional burden on the Building's or the
Office Park's utility systems or additional cost on account thereof, as the case
may be, Tenant shall, upon demand, reimburse Landlord for all additional costs
related thereto.  Further, if Tenant requires electricity in excess of the
quantity which is to be furnished as provided in Section 9.5(a) above, Landlord,
at the sole cost and expense of Tenant, will furnish and install such additional
wires, conduits, feeders, switchboards and appurtenances as Landlord may require
to supply such additional requirements of Tenant (if electricity therefor is
then available to Landlord without affecting the Office Park or Landlord's plans
therefor); provided that Landlord shall have no obligation to furnish any such
excess electricity unless the same shall be permitted by applicable laws and
insurance regulations and shall not cause or threaten permanent damage or injury
to the Building or the Premises or cause or create a dangerous or hazardous
condition or entail excessive or unreasonable alterations or repairs, or
interfere with or disturb other tenants or occupants of the Building or the
Office Park or interfere with Landlord's plans for the Office Park.

          (c) Landlord shall furnish and install the bulbs required within the
Premises as of the Commencement Date.  Thereafter, Landlord, at Tenant's
expense, shall replace and install all ballasts, lamps and bulbs (including, but
not limited to, incandescent and fluorescent) used in the Premises.  All such
replacements shall be of such type, color and size as are approved by Landlord.

          (d) Landlord shall not in any way be liable or responsible for any
loss, damage or expense which Tenant may sustain or incur if the quantity,
character, or supply of electricity is changed or is no longer available or
suitable for Tenant's requirements.

          (e) Landlord shall have the right to discontinue furnishing electric
power to the Premises at any time upon not less than thirty (30) days' notice to
Tenant, provided Landlord shall first have arranged for the supply of power for
Tenant's use to be provided to the Premises by the public utility company
furnishing electric service to the Building and shall, at Tenant's expense,
separately meter the Premises.  If Landlord exercises such right, from and after
the effective date of such termination, Landlord shall not be obligated to

                                      -19-
<PAGE>
 
furnish electricity to the Premises, and Tenant shall have no obligation to pay
any portion of Tenant's Electrical Charge.

     9.6  PARKING.  Landlord shall make available to Tenant parking on a
nonexclusive basis on the Land as provided in Section 2.2 of this Lease, except
that Tenant shall not have the right to make use of parking spaces (if any)
marked for visitor or handicapped parking or which are otherwise regulated by
Landlord.

     9.7  ADDITIONAL SERVICES.  In the event Tenant wishes to provide outside
services for the Premises over and above those services to be provided by
Landlord as set forth herein, Tenant shall obtain the prior written approval of
Landlord for the installation and/or utilization of such services.  ("Outside
services" shall include, but shall not be limited to, cleaning services,
television, so-called "canned music," security services, catering and the like.)
In the event Landlord approves the installation and/or utilization of such
services, such installation and utilization shall be at Tenant's sole cost, risk
and expense and subject to such requirements as Landlord may from time to time
elect to impose in connection therewith.

     9.8  INTERRUPTION OF SERVICES.  Landlord reserves the right to curtail,
suspend, interrupt and/or stop the supply of water, sewage, electricity,
cleaning, parking and other services, and to curtail, suspend, interrupt and/or
stop the use of the roads providing access to the Building, without thereby
incurring any liability to Tenant, when necessary by reason of accident or
emergency, or for repairs, alterations, replacements or improvements in the
judgment of Landlord desirable or necessary, or when prevented from supplying
such services or use by strikes, lockouts, difficulty of obtaining materials,
accidents or any other cause beyond Landlord's reasonable control, or by laws,
orders or inability, by exercise of reasonable diligence, to obtain electricity,
water, gas, steam, coal, oil or other suitable fuel or power, or by any other
condition not reasonably within the control of Landlord.  Except as expressly
provided below, no diminution or abatement of rent or other compensation, nor
any direct, indirect or consequential damages shall or will be claimed by Tenant
as a result of' nor shall this Lease or any of the obligations of Tenant be
affected or reduced by reason of' any such interruption, curtailment or
suspension.  Failure or omission on the part of Landlord to furnish any of the
foregoing services or use shall not be construed as an eviction of Tenant,
actual or constructive, nor, except as expressly provided below, entitle Tenant
to an abatement of rent, nor render Landlord liable in damages, nor release
Tenant from prompt fulfillment of any of its covenants under this Lease.  If
there shall occur any interruption or reduction of service(s), and if (i) such
interruption or reduction materially interferes with Tenant's use and enjoyment
of the Premises, and (ii) such interruption or reduction shall continue for ten
(10) days, then, commencing with the eleventh (11th) day of such interruption or
reduction and continuing until such time as such service(s) have been restored
to the extent necessary to avoid material interference with Tenant's use and
enjoyment of the Premises, Tenant shall be entitled to a reasonable reduction or
abatement of rent (consistent with the extent of interference with Tenant's
activities); provided, however, that Tenant shall not be entitled to such an
abatement or reduction if the interruption or reduction of service(s) results
from any condition not reasonably within Landlord's control.

                            INDEMNITY AND INSURANCE

     10.1 TENANT'S INDEMNITY.  TO the maximum extent this agreement may be made
effective according to law, Tenant agrees to indemnify and save harmless
Landlord from and against all loss, costs, penalties and liability damage claims
of whatever nature arising from any act, omission or negligence of Tenant or
Tenant's contractors, licensees, agents, servants or employees or arising from
any death, accident, injury or damage whatsoever caused to any person, or to the
property of any person, occurring after the date of this Lease until the end of
the Term of this Lease and thereafter, so long as Tenant is in occupancy of any
part of the Premises, in or about the Premises; or arising from any death,
accident, injury or damage occurring outside of the Premises but on the Property
or the Office Park, where such accident, damage or injury results or is claimed
to have resulted from any act or omission on the part of Tenant or Tenant's
agents or employees or independent contractors or invitees or suppliers.  This
indemnity shall, to the maximum extent this agreement may be made effective
according to law, also extend to all loss, costs, penalties, damage and claims
of whatever nature asserted against Landlord arising out of the use or occupancy
of, passage or travel over or upon, the Property or the Office Park by Tenant or
by any person claiming by, through or under Tenant (including, without
limitation, all employees, agents, contractors and customers of Tenant), or
arising out of any delivery to or service supplied to the Premises, or on
account of or based on anything whatsoever done on the Premises, except if the
same was caused by the negligence, fault or misconduct of Landlord, its agents,
servants or employees.  This indemnity and hold harmless agreement shall include
indemnity against all costs, expenses and liabilities incurred in or in
connection with any such claim or proceeding brought thereon, and the defense
thereof with counsel approved by Landlord.

     10.2 LIABILITY INSURANCE.  Tenant shall keep in force, at its own expense,
so long as this Lease remains in effect and during such other times as Tenant
occupies the Premises or any part thereof, comprehensive general liability
insurance including broad form endorsement contractual liability, with respect
to the Premises, with combined single limits in an amount not less than the
amount specified in Section 1.2 (and in such higher amounts as may reasonably be
required by Landlord from time to time), and so-called "All Risk" insurance on
(and in an amount not less than the full replacement value of) Tenant's personal
property, including trade fixtures, floor coverings, furniture and other
property removable by Tenant.  All such insurance shall be written by companies
and on forms acceptable to Landlord.  Tenant will further deposit the policy or
policies of such insurance or certificates thereof with Landlord, which policies
shall name Landlord and/or its designee(s) as additional named insured, and
shall also contain a provision stating that such policy or policies shall not be
cancelled or amended except after thirty (30) days written notice to Landlord.
If the nature of Tenant's business is such as to place all or any of its
employees under the coverage of local workmen's compensation or similar
statutes, Tenant shall also keep in force, at its expense, so long as this Lease
remains in effect and during such other times as Tenant occupies the Premises or
any part thereof, workmen's compensation or similar insurance affording
statutory coverage and containing statutory limits.  If Tenant shall not comply
with its covenants made in this Section 10.2, Landlord may cause insurance as

                                      -21-
<PAGE>
 
aforesaid to be issued, and, in such event, Tenant agrees to pay, as additional
rent and charge, the premium for such insurance upon Landlord's demand.

     10.3 TENANT'S RISK.  To the maximum extent this agreement may be made
effective according to law, Tenant agrees to use and occupy the Premises and to
use such other portions of the Building, the Property and the Common Property as
Tenant is herein given the right to use at Tenant's own risk; and Landlord shall
have no responsibility or liability for any loss of or damage to Tenant's
Removable Property (including, without limitation, damage resulting from the
breaking, bursting, or leaking of pipes, conduits, electrical lines and the like
or from any other cause or condition).  The provisions of this Section shall be
applicable from and after the execution of this Lease and until the end of the
Term, and during such further period as Tenant may use or be in occupancy of any
part of the Premises or the Building.

     10.4 INJURY CAUSED BY THIRD PARTIES.  To the maximum extent this agreement
may be made effective according to law, Tenant agrees that Landlord shall not be
responsible or liable to Tenant, or to those claiming by, through or under
Tenant, for any loss or damage that may be occasioned by or through the acts or
omissions of persons occupying adjoining premises or any part of the premises
adjacent to or connecting with the Premises or any part of the Property or the
Office Park or otherwise.

     10.5 LANDLORD'S NEGLIGENCE.  Notwithstanding anything to the contrary set
forth in the foregoing provisions of this Article X, Landlord agrees to
indemnify and hold harmless Tenant from and against all loss, cost and expense
resulting from Landlord's negligence, or from any other tortious act of
Landlord.

                                  ARTICLE  XI
                         LANDLORD'S ACCESS TO PREMISES

     11.1 LANDLORD'S RIGHTS.  Landlord shall have the right to enter the
Premises at all reasonable hours for the purpose of inspecting or making repairs
to the same, and Landlord shall also have the right to make access available at
all reasonable hours to prospective or existing mortgagees, purchasers or
tenants of any part of the Property.

                                 ARTICLE  XII
                          FIRE, EMINENT DOMAIN, ETC.

     12.1 ABATEMENT OF RENT.  If the Premises shall be damaged by fire or
casualty, Basic Rent payable by Tenant shall abate proportionately for the
period in which, by reason of such damage, there is substantial interference
with Tenant's uses of the Premises, having regard to the extent to which Tenant
may be required to discontinue Tenant's use of all or a portion of the Premises,
but such abatement or reduction shall end if and when Landlord shall have
substantially restored the Premises to the condition which they were in prior to
such damage (subject, however, to the provisions of applicable zoning and
building regulations).  If the Premises shall be affected by any exercise of the
power of eminent domain, Basic Rent payable by Tenant shall be justly and
equitably abated and reduced according to the nature and extent of the loss of
use thereof suffered by Tenant.

                                      -22-
<PAGE>
 
     12.2 LANDLORD'S RIGHT OF TERMINATION.  If (a) the Premises or (b) the
Building or (c) the parking area serving the Building or (d) any roadway or
other facility within the Common Property necessary for the use and enjoyment of
the Premises (hereinafter referred to as "Critical Common Facilities") are
substantially damaged by fire or casualty (the term "substantially damaged"
meaning damage of such a character that the same cannot reasonably be expected
to be repaired within sixty (60) days from the time that repair work would
commence), or if access to the Property through the Common Property is, or if
(i) any part of the Building or (ii) a substantial part of the parking area
serving the Building or (iii) Critical Common Facilities are, taken by any
exercise of the right of eminent domain, then Landlord shall have the right to
terminate this Lease (even if Landlord's entire interest in the Premises may
have been divested) by giving notice of Landlord's election so to do within 90
days after the occurrence of such casualty or the effective date of such taking,
whereupon this Lease shall terminate 30 days after the date of such notice with
the same force and effect as if such date were the date originally established
as the expiration date hereof.

     12.3 RESTORATION.  IF this Lease shall not be terminated pursuant to
Section 12.2, Landlord shall thereafter use due diligence to restore the
Premises to proper condition for Tenant's use and occupation, provided that
Landlord's obligation shall be limited to the amount of insurance proceeds or
condemnation awards made available to Landlord therefor. If, for any reason,
such restoration shall not be substantially completed within six (6) months
after the occurrence of the casualty or taking (which six-month period may be
extended for such periods of time as Landlord is prevented from proceeding with
or completing such restoration for any cause beyond Landlord's reasonable
control).  Tenant shall have the right to terminate this Lease by giving notice
to Landlord thereof within thirty (30) days after the expiration of such period
(as so extended).  Upon the giving of such notice, this Lease shall cease and
come to an end without further liability or obligation on the part of either
party unless, within such 30-day period, Landlord substantially completes such
restoration.  Such right of termination shall be Tenant's sole and exclusive
remedy at law or in equity for Landlord's failure to complete such restoration.

     12.4 AWARD.  Landlord shall have and hereby reserves and excepts, and
Tenant hereby grants and assigns to Landlord, all rights to recover for damages
to the Property and the leasehold interest hereby created, and to compensation
accrued or hereafter to accrue by reason of taking, damage or destruction, and
by way of confirming the foregoing, Tenant hereby grants and assigns, and
covenants with Landlord to grant and assign to Landlord, all rights to such
damages or compensation.  Nothing contained herein shall be construed to prevent
Tenant from prosecuting in any separate condemnation proceedings a claim for the
value of any of Tenant's Removable Property installed in the Premises by Tenant
at Tenant's expense and for relocation expenses, provided that such action shall
not affect the amount of compensation otherwise recoverable by Landlord from the
taking authority and shall be prosecuted in a proceeding separate and apart from
Landlord.

     12.5 TEMPORARY TAKING.  In the event of taking of the Premises or any part
thereof for temporary use (that is, for a use which is expected to end prior to
the expiration of the Term), (i) this Lease shall be and remain unaffected
thereby and rent shall not abate, and (ii) Tenant shall be entitled to receive
for itself such portion or portions of any award 

                                      -23-
<PAGE>
 
made for such use with respect to the period of the taking which is within the
Term, provided that if such taking shall remain in force at the expiration or
earlier termination of this Lease, Tenant shall then pay to Landlord a sum equal
to the reasonable cost of performing Tenant's obligations under this Lease with
respect to surrender of the Premises and upon such payment shall be excused from
such obligations.

                                 ARTICLE  XIII
                                    DEFAULT

     13.1 TENANT'S DEFAULT.

          (a) If at any time subsequent to the date of this Lease any one or
more of the following events (each herein referred to as a "Default of Tenant")
shall happen:

                    (i)   Tenant shall fail to pay the Basic Rent, Escalation
          Charges or other charges hereunder when due and such failure shall
          continue for three (3) full business days after notice to Tenant from
          Landlord; or

                    (ii)  Tenant shall neglect or fail to perform or observe any
          other covenant herein contained on Tenant's part to be performed or
          observed and Tenant shall fall to remedy the same within thirty (30)
          days after written notice to Tenant specifying such neglect or failure
          (or, if such failure is of such a nature that Tenant cannot reasonably
          remedy the same within such thirty (30) day period, Tenant shall fail
          to commence promptly to remedy the same and to prosecute such remedy
          to completion with diligence and continuity); or

                    (iii) Tenant's leasehold interest in the Premises shall be
          taken on execution or by other process of law directed against Tenant;
          or

                    (iv)  Tenant shall make an assignment for the benefit of
          creditors or shall file a voluntary petition in bankruptcy or shall be
          adjudicated bankrupt or insolvent, or shall file any petition or
          answer seeking any reorganization,  arrangement,  composition,
          readjustment, liquidation, dissolution or similar relief for itself
          under any present or future Federal, State or other statute, law or
          regulation for the relief of debtors, or shall seek or consent to or
          acquiesce in the appointment of any trustee, receiver or liquidator of
          Tenant or of all or any substantial part of its property, or shall
          admit in writing its inability to pay its debts generally as they
          become due; or

                    (v)   A petition shall be filed against Tenant in bankruptcy
          or under any other law seeking any reorganization, arrangement,
          composition, readjustment, liquidation, dissolution, or similar relief
          under any present or future Federal, State or other statute, law or
          regulation and shall remain undismissed or unstayed for an aggregate

                                      -24-
<PAGE>
 
          of Sixty (60) days (whether or not consecutive), or if any debtor in
          possession (whether or not Tenant), trustee, receiver, or liquidator
          of Tenant or of all or any substantial part of its property or of the
          Premises shall be appointed without the consent or acquiescence of
          Tenant and such appointment shall remain unvacated or unstayed for an
          aggregate of sixty (60) days (whether or not consecutive); or

                    (vi)  Tenant shall abandon or vacate the Premises, or shall
          otherwise indicate its unwillingness to continue to perform its
          obligations hereunder;

then in any such case (1) if such Default of Tenant shall occur prior to the
Commencement Date, this Lease shall ipso facto, and without further act on the
part of Landlord, terminate, and (2) if such Default of Tenant shall occur after
the Commencement Date, Landlord may terminate this Lease by notice to Tenant,
and this Lease shall come to an end on the date of such notice, as fully and
completely as if such date were the date herein originally fixed for the
expiration of the Term; and Tenant will then quit and surrender the Premises to
Landlord, but Tenant shall remain liable as hereinafter provided.

          (b) If this Lease shall have been terminated as provided in this
Article, or if any execution or attachment shall be issued against Tenant or any
of Tenant's property whereupon the Premises shall be taken or occupied by
someone other than Tenant, then Landlord may, without notice, re-enter the
Premises, either by force, summary proceedings, ejectment or otherwise, and
remove and dispossess Tenant and all other persons and any and all property from
the same, as if this Lease had not been made, and Tenant hereby waives the
service of notice of intention to re-enter or to institute legal proceedings to
that end.

          (c) In the event of any termination, Tenant shall pay the Basic Rent,
Escalation Charges and other sums payable hereunder up to the time of such
termination, and thereafter Tenant, until what would have been the end of the
Term in the absence of such termination, and whether or not the Premises shall
have been relet, shall be liable to Landlord for, and shall pay to Landlord, as
liquidated current damages, the Basic Rent, Escalation Charges and other sums
which would be payable hereunder if such termination had not occurred, less the
net proceeds, if any, of any reletting of the Premises for the corresponding
period, after deducting all expenses in connection with such reletting,
including, without limitation, all repossession costs, brokerage commissions,
legal expenses, attorneys' fees, advertising costs, expenses of employees,
alteration costs and expenses of preparation for such reletting.  Tenant shall
pay such current damages to Landlord monthly on the days on which Basic Rent
would have been payable hereunder if this Lease had not been terminated.

          (d) At any time after such termination, whether or not Landlord shall
have collected any such current damages, as liquidated final damages and in lieu
of all such current damages beyond the date of such demand, Tenant shall pay to
Landlord upon demand an amount equal to the excess, if any, of the Basic Rent,
Escalation Charges and other sums as hereinbefore provided which would be
payable hereunder from the date of such demand (assuming that, for the purposes
of this paragraph, annual payments by Tenant 

                                      -25-
<PAGE>
 
on account of Taxes and Operating Expenses would be the same as the payments
required for the immediately preceding Operating or Tax Year) for what would be
the then unexpired Term if the same remained in effect, over the then fair net
rental value of the Premises for the same period.

          (e) In case of any Default by Tenant, following any re-entry,
termination and dispossession by summary proceedings or otherwise, Landlord may
(i) re-let the Premises or any part or parts thereof either in the name of
Landlord or otherwise, for a term or terms which may at Landlord's option be
equal to or less than or exceed the period which would otherwise have
constituted the balance of the Term of this Lease and may grant concessions or
free rent to the extent that Landlord considers advisable and necessary to re-
let the same and (ii) may make such alterations, repairs and decorations in the
Premises as Landlord in its sole judgment considers advisable and necessary for
the purpose of re-letting the Premises; and the making of such alterations,
repairs and decorations shall not operate or be construed to release Tenant from
liability hereunder as aforesaid.  Landlord shall in no event be liable in any
way whatsoever for failure to re-let the Premises, or, in the event that the
Premises are re-let, for failure to collect the rent under such re-letting.
Tenant hereby expressly waives any and all rights of redemption granted by or
under any present or future laws in the event of Tenant being evicted or
dispossessed, or in the event of Landlord obtaining possession of the Premises,
by reason of the violation by Tenant of any of the conditions of this Lease.

          (f) If a Guarantor of the Lease is named in Section 1.2, the happening
of any of the events described in paragraphs (a)(iv) or (a)(v) of this Section
13.1 with respect to the Guarantor shall constitute a Default of Tenant
hereunder.

          (g) The specified remedies to which Landlord may resort hereunder are
not intended to be exclusive of any remedies or means of redress to which
Landlord may at any time be entitled lawfully, and Landlord may invoke any
remedy (including the remedy of specific performance) allowed at law or in
equity as if specific remedies were not herein provided for.

          (h) All costs and expenses incurred by or on behalf of Landlord
(including, without limitation, attorneys' fees and expenses) in enforcing its
rights hereunder or occasioned by any Default of Tenant shall be paid by Tenant.

     13.2 LANDLORD'S DEFAULT.  Landlord shall in no event be in default in the
performance of any of Landlord's obligations hereunder unless and until Landlord
shall have failed to perform such obligation within thirty (30) days, or such
additional time as is reasonably required to correct any such default, after
notice by Tenant to Landlord specifying wherein Landlord has failed to perform
any such obligations.  After receipt of any such notice, Landlord shall commence
the curing of any such default with reasonable promptness.

                                 ARTICLE  XIV
                           MISCELLANEOUS PROVISIONS

      14.1  EXTRA HAZARDOUS USE.  Tenant covenants and agrees that Tenant
will not do or permit anything to be done in or upon the Premises, or bring in
anything or keep anything therein, which shall invalidate or increase the rate
of property or liability insurance on the Premises or the Property above the
standard rate applicable to premises being occupied for the Permitted Uses; and
Tenant agrees that, in the event that Tenant shall do any of the foregoing,
Tenant will promptly pay to Landlord, on demand, any such increase resulting
therefrom, which shall be due and payable as an additional charge hereunder.

      14.2  WAIVER.

            (a) Failure on the part of Landlord or Tenant to complain of any
action or non-action on the part of the other, no matter how long the same may
continue, shall never be a waiver by Tenant or Landlord, respectively, of any of
the other's rights hereunder. Further, no waiver at any time of any provisions
hereof by Landlord or Tenant shall be construed as a waiver of any of the other
provisions hereof' and a waiver at any time of any of the provisions hereof
shall not be construed as a waiver at any subsequent time of the same
provisions.  The consent or approval of Landlord or Tenant to or of any action
by the other requiring such consent or approval shall not be construed to waive
or render unnecessary Landlord's or Tenant's consent or approval to or of any
subsequent similar act by the other.

            (b) No payment by Tenant, or acceptance by Landlord, of a lesser
amount than shall be due from Tenant to Landlord shall be treated otherwise than
as a payment on account.  The acceptance by Landlord of a check for a lesser
amount with an endorsement or statement thereon, or upon any letter accompanying
such check, that such lesser amount is payment in full, shall be given no
effect, and Landlord may accept such check without prejudice to any other rights
or remedies which Landlord may have against Tenant.  The delivery of keys to any
employee of Landlord or to Landlord's agent or any employee thereof shall not
operate as a termination of this Lease or a surrender of the Premises.

      14.3  COVENANT OF QUIET ENJOYMENT.  Tenant, subject to the terms and
provisions of this Lease, on payment of the Basic Rent and Escalation Charges
and other sums and charges due hereunder and observing, keeping and performing
all of the other terms and provisions of this Lease on Tenant's part to be
observed, kept and performed, shall peaceably and quietly have, hold and enjoy
the Premises for the Term without hindrance or molestation by anyone claiming
by, through or under Landlord, subject, however, to the rights of the holders of
all mortgages affecting the property from time to time; provided, however,
Landlord may at any time and from time to time, without the same constituting a
breach of Landlord's covenant of quiet enjoyment or an actual or constructive
eviction, and without incurring any liability to Tenant or otherwise affecting
any of Tenant's obligations under this Lease, make such changes, alterations,
additions, improvements, repairs or replacements in or to the interior and
exterior of the Building (including the Premises) and the fixtures and equipment
thereof, and in or to the Property and the Office Park (including, without
limitation, landscaping, the construction of additional structures, signs and
buildings, 

                                      -27-
<PAGE>
 
the relocation of access roads situated within the Office Park and the redesign
or temporary closing of parking areas and other common facilities and roads
serving the Building and the Office Park) as Landlord may deem necessary or
desirable, and change the arrangement and/or location of entrances or
passageways, doors and doorways, corridors, elevators, or other public parts of
the Building, provided further, however, that there be no unreasonable
interference with the conduct of Tenant's business or obstruction of access to
the Premises by Tenant. Nothing contained in this Section 14.3 shall be deemed
to relieve Tenant of any duty, obligation or liability with respect to making
any repair, replacement or improvement or complying with any law, order or
requirement of any governmental or other authority. Landlord reserves the right,
at any time and from time to time, to change the name and address of the
Building and the Office Park.

      14.4  LANDLORD'S LIABILITY.

            (a) Tenant specifically agrees to look solely to Landlord's then
equity interest in the Property at the time owned by Landlord, for recovery of
any judgment from Landlord; it being specifically agreed that neither Landlord
(original or successor) nor any partner, beneficiary, shareholder, officer,
director, employee or any other party holding any interest in or being
affiliated with Landlord shall ever be personally liable for any such judgment,
or for the payment of any monetary obligation to Tenant.  The provision
contained in the foregoing sentence is not intended to, and shall not, limit any
right that Tenant might otherwise have to obtain injunctive relief against
Landlord or Landlord's successors in interest, or to take any action not
involving the personal liability of Landlord (original or successor) to respond
in monetary damages from Landlord's assets other than Landlord's equity interest
in the Property.

            (b) In no event shall Landlord ever be liable for any indirect or
consequential damages suffered by Tenant from whatever cause.

      14.5  RULES AND REGULATIONS.  Tenant shall abide by rules and
regulations from time to time established by Landlord (including, without
limitation, the Rules and Regulations annexed hereto as Exhibit B), it being
agreed that such rules and regulations will be established and applied by
Landlord in a non-discriminatory fashion, such that all rules and regulations
shall be generally applicable to other tenants of the Building of similar nature
to the Tenant named herein (having in mind the location and nature of the
Premises and the nature of Tenant's business activities).  Landlord agrees to
use reasonable efforts to insure that any such rules and regulations are
uniformly enforced, but Landlord shall not be liable to Tenant for violation of
the same by any other tenant or occupant of the Building, or persons having
business with them.  Landlord expressly reserves the right to waive application
of any rule or regulation as to any tenant.

      14.6  ADDITIONAL CHARGES.  If Tenant shall fail to pay when due any
sums under this Lease designated as an additional charge, additional rent or
Escalation Charge or any other charge hereunder, Landlord shall have the same
rights and remedies as Landlord has hereunder for failure to pay Basic Rent.

                                      -28-
<PAGE>
 
      14.7  INVALIDITY OF PARTICULAR PROVISIONS.  If any term or provision of
this Lease, or the application thereof to any person or circumstance, shall, to
any extent, be invalid or unenforceable, the remainder of this Lease, or the
application of such term or provision to persons or circumstances other than
those as to which it is held invalid or unenforceable, shall not be affected
thereby, and each term and provision of this Lease shall be valid and shall be
enforced to the fullest extent permitted by law.

      14.8  PROVISIONS BINDING, ETC.  Except as herein provided, the terms
hereof shall be binding upon and shall inure to the benefit of the successors
and assigns, respectively, of Landlord and Tenant, and, if Tenant shall be an
individual, upon and to his heirs, executors, administrators, successors and
assigns.  Each term and each provision of this Lease to be performed by Tenant
shall be construed to be both a covenant and a condition. The reference
contained to successors and assigns of Tenant is not intended to constitute a
consent to assignment by Tenant, but has reference only to those instances in
which Landlord may later give consent to a particular assignment (or as to which
Landlord's consent is not required), pursuant to Article VIII hereof.

      14.9  RECORDING.  Tenant agrees not to record this Lease, but each
party hereto agrees, on the request of the other, to execute a so-called notice
of lease in recordable form and complying with applicable law and reasonably
satisfactory to Landlord's attorneys.  In no event shall such document set forth
the rent or other charges payable by Tenant under this Lease; and any such
document shall expressly state that it is executed pursuant to the provisions
contained in this Lease, and is not intended to vary the terms and conditions of
this Lease.

      14.10 NOTICES.  Whenever, by the terms of this Lease, notice shall or
may be given either to Landlord or to Tenant, such notice shall be in writing
and shall be sent by registered mail, return receipt requested, postage prepaid,
or by prepaid Federal Express or other similar overnight delivery service:

     If intended for Landlord, addressed to Landlord at Landlord's Address (or
     to such other address or addresses as may from time to time hereafter be
     designated by Landlord by like notice); and

     If intended for Tenant, addressed to Tenant at the Premises (or to such
     other address or addresses as may from time to time hereafter be designated
     by Tenant by like notice); provided, however, that, prior to the
     Commencement Date, notices intended for Tenant shall be addressed to
     Tenant's Original Address.

     All such notices shall be effective upon receipt by or tender for delivery
to the intended recipient thereof.

      14.11 WHEN LEASE BECOMES BINDING.  The submission of this document for
examination and negotiation does not constitute an offer to lease, or a
reservation of' or option for, the Premises, and this document shall become
effective and binding only upon execution and delivery by both Landlord and
Tenant.  Except for the provisions of any written instrument or agreement
executed substantially concurrently herewith by Landlord 

                                      -29-
<PAGE>
 
and Tenant, all negotiations, considerations, representations and understandings
between Landlord and Tenant are incorporated herein and this Lease expressly
supersedes any proposals or other written documents executed prior hereto. This
Lease may be modified or altered only by written agreement between Landlord and
Tenant, and no act or omission of any employee or agent of Landlord shall alter,
change or modify any of the provisions hereof.

      14.12 PARAGRAPH HEADINGS.  The paragraph headings in this instrument
are for convenience and reference only, and the words contained therein shall in
no way be held to explain, modify, amplify or aid in the interpretation,
construction or meaning of the provisions of this Lease.

      14.13 SUBORDINATION; ATTORNMENT.

            (a) Tenant's rights under this Lease are and shall always be
subordinate to the operation and effect of any lease of land only or of land and
buildings in a sale-leaseback transaction, and any mortgage, deed of trust or
other security instrument now or hereafter placed upon the Property, or any part
or parts thereof' by Landlord.  This clause shall be self-operative, and no
further instrument of subordination shall be required.  In confirmation thereof
Tenant shall execute such further assurances as may be requisite.  In addition,
Tenant agrees to attorn to any successor in interest to Landlord whether by
purchase, foreclosure, sale in lieu of foreclosure, power of sale, termination
of any lease of land only or land and buildings in a sale-leaseback transaction
or otherwise, if so requested or required by such successor in interest, and
Tenant agrees, upon demand, to execute such agreement or agreements in
confirmation of such attornment as may be requested by Landlord.  However,
Tenant's obligation of subordination and attornment with respect to any mortgage
hereafter encumbering the Property shall be conditioned upon the execution by
the holder of such mortgage of an agreement, in the form then commonly used by
such holder, to the effect that, notwithstanding any foreclosure of such
mortgage or other exercise by the holder of its rights thereunder, Tenant shall
be permitted to continue to occupy the Premises and exercise its rights
hereunder, so long as there shall occur no condition which, pursuant to the
terms of this Lease, would have permitted Landlord to terminate this Lease or
otherwise interfere with Tenant's rights hereunder.  Landlord or its mortgagee,
any ground lessor or other similar secured party, may, at its option, make this
Lease superior to any such mortgage, ground lease or other security instrument
by giving Tenant ten (10) days prior written notice and no other documentation
shall be necessary to effect such change.

            (b) If any person shall succeed to all or part of Landlord's
interest in the Premises upon the exercise of any remedy provided for in any
mortgage of the Premises now or hereafter recorded, (i) Tenant shall attorn to
and recognize such person as Tenant's landlord as above provided and this Lease
shall continue in full force and effect as a direct lease between such person
and Tenant as fully and with the same force and effect as if this Lease had
originally been entered into by such person and Tenant, except that such person
shall not be liable for any act or omission of Landlord occurring prior to such
person's succession to title nor be subject to any offset, defense or
counterclaim accruing prior to such person S succession to title, nor be bound
by any modification of this Lease or any waiver, compromise, release or
discharge of any obligation of Tenant hereunder unless such 

                                      -30-
<PAGE>
 
modification, waiver, compromise, release or discharge shall have been
specifically consented to in writing by the mortgagee under said mortgage, nor
be bound by any payment of Basic Rent or Escalation Charges which Tenant has
paid more than one month in advance (other than deposits in the nature of
security deposits), and (ii) such person and each person succeeding to its
interest in the Premises shall not be liable for any warranty or guaranty of
Landlord under this Lease and shall be liable for the performance and observance
of the other covenants and conditions to be performed and observed by Landlord
under this Lease only with respect to the period during which such person shall
own such interest.

            (c) Concurrently with any notification from Tenant to Landlord
concerning any default by Landlord in the performance of its obligations
hereunder, Tenant shall provide a copy of such notice to any mortgagee or ground
lessor of the Property of which Tenant has received notice.  Thereafter, Tenant
will not exercise any right to terminate this Lease on account of such default
unless such mortgagee or ground lessor has failed, within a reasonable time
after its receipt of such notice from Tenant, to remedy such default on behalf
of Landlord.

            (d) Neither receipt of a collateral assignment of Landlord's
interest hereunder nor receipt of transfer of title to the Property when
followed by a ground lease back to Landlord shall be deemed to constitute an
assumption by the mortgagee or transferee (as the case may be) of the
obligations of Landlord hereunder, unless such obligations shall be expressly
assumed, in writing, by such mortgagee or transferee.

            (e) If, in connection with obtaining construction, interim or
permanent financing for the Property, the lender shall request reasonable
modifications in this Lease as a condition to such financing, Tenant will not
unreasonably withhold, delay or defer its consent thereto, provided that such
modifications do not increase the obligations of Tenant hereunder, or affect
Tenant's rental and other monetary obligations hereunder, the Term or any of the
other "business" terms contained herein, or materially adversely affect the
leasehold interest hereby created or Tenant's rights hereunder.

      14.14 ASSIGNMENT OF RENTS AND TRANSFER OF TITLE.

            (a) With reference to any assignment of Landlord's interest in this
Lease, or the rents payable hereunder, conditional in nature or otherwise, which
assignment is made to the holder of a mortgage on property which includes the
Premises, Tenant agrees that the execution thereof by Landlord, and the
acceptance thereof by the holder of such mortgage shall never be treated as an
assumption by such holder of any of the obligations of Landlord hereunder unless
such holder shall, by notice sent to Tenant, specifically otherwise elect, and
that, except as aforesaid, such holder shall be treated as having assumed
Landlord's obligations hereunder only upon foreclosure of such holder's mortgage
and the taking of possession of the Premises.

            (b) In the event of any transfer of title to the Property by
Landlord, Landlord shall thereafter be entirely freed and relieved from the
performance and observance of all covenants and obligations hereunder.
Furthermore, Landlord and each succeeding holder of Landlord's interest under
this Lease shall be responsible only for defaults

                                      -31-
<PAGE>
 
hereunder arising during or prior to the period during which such party holds
Landlord's interest hereunder.

      14.15 STATUS REPORT.  Tenant agrees that, at any time and from time to
time at reasonable intervals, within ten (10) days after written request by
Landlord, Tenant will execute, acknowledge and deliver to Landlord and/or to
Landlord's designee, mortgagee or other similar secured party as may be
designated by Landlord, a certificate stating that this Lease is unmodified and
in full force and effect (or that the same is in full force and effect as
modified, listing the instruments of modification), the dates to which rent and
other charges have been paid, and whether or not, to the best of Tenant's
knowledge, Landlord is in default hereunder (and if so, specifying the nature of
the default), and containing such other statements as to the status of matters
under this Lease as Landlord may require, it being intended that any such
statement delivered pursuant to this paragraph may be relied upon by any
mortgagee, ground lessor or assignee of Landlord's interest in the Premises.

      The failure of Tenant to execute and deliver such certificate shall
constitute a default hereunder, in which event, in addition to any other
remedies which Landlord may have under this Lease as a result of Tenant's
default, Landlord is hereby authorized, as attorney and agent of Tenant, to
execute such certificate; and in such event Tenant hereby confirms and ratifies
any such certificate executed by virtue of the power of attorney hereby granted.

      14.16 REMEDYING DEFAULTS.  Landlord shall have the right, but shall not
be required, to pay such sums or do any act which requires the expenditure of
monies which may be necessary or appropriate by reason of the failure or neglect
of Tenant to perform any of the provisions of this Lease, and in the event of
the exercise of such right by Landlord, Tenant agrees to pay Landlord forthwith
upon demand all such sums, together with interest thereon at a rate (the
"Default Rate") equal to the greater of (i) 3% over the "prime rate" in effect
from time to time at Bank of Boston and (ii) 18% per annum, as an additional
charge. (However, in no event shall the Default Rate be greater than the highest
rate of interest which may lawfully be charged.) Any payment of Basic Rent,
Escalation Charges or other sums payable hereunder not paid when due shall, at
the option of Landlord, bear interest at the Default Rate from the due date
thereof which interest shall be payable forthwith upon demand by Landlord.

      14.17 HOLDING OVER.  Any holding over by Tenant after the expiration or
earlier termination of the Term shall be treated as a daily tenancy at
sufferance at a rate equal to 1  1/2 times the sum of the Basic Rent and
Escalation Charges herein provided (prorated on a daily basis), and shall
otherwise be on the terms and conditions set forth in this Lease as far as
applicable.

      14.18 WAIVER OF SUBROGATION.  Landlord shall cause each insurance
policy carried by it insuring the Building against loss by fire or any of the
casualties covered by standard extended coverage to be written in such a manner
as to provide that the insurer waives all right of recovery by way of
subrogation against Tenant in connection with any loss or damage covered by the
policy.  Tenant shall cause each insurance policy carried by it insuring the
Premises as well as the contents thereof' including trade fixtures and personal
property, against loss by fire or any of the casualties covered by standard
extended coverage 

                                      -32-
<PAGE>
 
to be written in such a manner as to provide that the insurer waives all right
of recovery by way of subrogation against Landlord in connection with any loss
or damage covered by the policy. Neither party hereto shall be liable to the
other for any loss or damage caused by fire or any of the casualties covered by
standard extended coverage, which loss or damage is covered by the insurance
policies maintained by the other party, provided that such policies are not
invalidated by such waiver; and provided further that, if either party shall be
unable to obtain the waiver of subrogation required by this Section without
additional premium therefor, then unless the party claiming the benefit of such
waiver shall agree to pay such party for the cost of such additional premium
within thirty (30) days after notice of the statement setting forth such
requirement and the amount of additional premium, such waiver shall be of no
force and effect between such party and the claiming party; and provided further
that neither party hereto shall be freed of liability to the extent of any
deductible under the other party's insurance, or to the extent to which such
other party's loss is greater than the coverage provided by the insurance policy
to which the waiver of subrogation required by this Section applies.

      14.19 SURRENDER OF PREMISES.  Upon the expiration or earlier
termination of the Term, Tenant shall peaceably quit and surrender to Landlord
the Premises in neat and clean condition and in good order, condition and
repair, together with all alterations, additions and improvements which may have
been made or installed in, on or to the Premises prior to or during the Term,
excepting only ordinary wear and use and damage by fire or other casualty for
which, under other provisions of this Lease, Tenant has no responsibility of
repair or restoration.  Tenant shall remove all of Tenant's Removable Property
and, to the extent specified by Landlord, all alterations and additions made by
Tenant and all partitions wholly within the Premises unless installed initially
by Landlord in preparing the Premises for Tenant's occupancy pursuant to Article
IV; and shall repair, to the satisfaction of Landlord, any damage to the

                                     LEASE


     THIS Lease is between STEVEN M. ROBERTS, TRUSTEE OF NORTHERNEDGE/PLANT ONE
REALTY TRUST, under Declaration of Trust dated December 20, 1988, recorded with
the Hampden County Registry of Deeds at Book 7065, Page 1, with a usual place of
business at 93 West Broad Street, Springfield, Massachusetts, hereinafter
referred to as the "Lessor," and PHYSICIANS QUALITY CARE, INC., a Massachusetts
corporation with a usual place of business at 950 Winter Street, Suite 2410,
Waltham, Massachusetts, hereinafter referred to as the "Lessee."

     The Lessor and the Lessee agree as follows:

     1.   Leased Premises.

          (a) The Lessor hereby leases to the Lessee, and the Lessee hereby
leases from the Lessor, for the term and upon the conditions contained in this
Lease, that portion of the second floor of the building located at 354 Birnie
Avenue, Springfield, Massachusetts (the "Building") outlined in blue and labeled
as "Area #2" on Exhibit A, which is attached hereto and made a part hereof (the
"Leased Premises").  The Leased Premises consist of approximately 2,410 rentable
square feet of space.  The Building is located within and comprises part of
NorthernEdge Condominium (the "Project").

          (b) The Lessor leases the Leased premises to the Lessee together with
the following:

               (i) The nonexclusive right in favor of the Lessee, its agents,
          servants, employees and invitees, to park their automobiles within the
          common areas of the project which are identified as "Permitted Parking
          Areas" on Exhibit B.  All such parking rights are granted by the
          Lessor to the Lessee in common with all others entitled thereto and
          only to the extent available and on an equitable basis.  The Lessor
          agrees that it shall not change the Permitted Parking Areas in any
          manner that materially reduces the number of parking spaces available
          to the Lessee or in any manner that materially interferes with access
          to the Leased 
<PAGE>
 
          Premises from the Permitted Parking Areas or results in a substantial
          variation in the location of the Permitted Parking Areas; and

               (ii) The right of access, in common with all others entitled
          thereto, to the Leased Premises through the common areas located
          within the Buildings and the entrances to the Buildings, as more
          particularly described on Exhibit A.

          (c) Except as otherwise expressly provided in this Lease, the Lessor
hereby reserves to itself (i) the right to maintain, use, repair and replace
pipes, ducts, wires, meters and any other equipment, machinery, apparatus, and
fixtures located within or without the Leased Premises which service other parts
of the Building; (ii) the right to make changes, alterations, and additions to
the Building, common areas, and common facilities provided that any such
changes, alterations or additions do not unreasonably structurally change the
interior of the Leased Premises and provided that reasonable access and service
to the Leased Premises is provided; and (iii) the right to enter the Leased
Premises for repair and maintenance purposes upon reasonable prior notice to
Lessee, and for emergency purposes at any time, without notice.  The Lessor and
the Lessee agree that the requirement that the Lessor provide the Lessee with
reasonable prior notice in connection with the exercise by the Lessor of its
right of entry with respect to the Leased Premises shall be satisfied if the
Lessor provides the Lessee with prior notice at least twenty-four (24) hours
prior to the exercise by the Lessor of its right of entry, except in the event
of an emergency.

     2.   Use by Lessee.

     The Lessee agrees that it will use the Leased Premises only for general
office purposes.  The Lessee shall not use or occupy the Leased Premises for any
other purpose or business without the prior written consent of the Lessor.  The
Lessee shall observe and comply with the Lessor's reasonable Rules and
Regulations as promulgated from time to time 

                                      -2-
<PAGE>
 
by the Lessor with respect to the Buildings and/or the Project. The Rules and
Regulations shall be generally applicable to all tenants or other occupants of
the Buildings and/or the Project.

     3.   Commencement Date; Tenant Improvement Allowance.

          (a) The term of this Lease and the Lessee's obligation to pay rent
hereunder shall commence upon December 1, 1996 (the "Commencement Date").  The
Lessee agrees to accept possession of the Leased Premises on the Commencement
Date "AS IS, WHERE IS," without any requirement that the Lessor perform any work
or make any alterations with respect to the Leased Premises or any portion
thereof, subject to the Lessor's obligations pursuant to Paragraph 3(b) below.

          (b) The Lessor and the Lessee acknowledge that the Lessee intends to
make certain improvements to the Leased Premises (the "Lessee's Improvements").
The Lessee's Improvements shall be subject to the prior approval of the Lessor,
which shall not be unreasonably withheld or delayed.  The Lessor agrees to
reimburse the Lessee for the cost of the Lessee's Improvements, up to a total
reimbursement amount of Sixteen Thousand Eight Hundred Seventy ($16,870.00)
Dollars (the "Allowance").  The Allowance shall be paid by the Lessor to the
Lessee upon presentation by the Lessee to the Lessor of invoices confirming the
payment by the Lessee of costs and expenses incurred in connection with the
performance of the work required to complete the Lessee's Improvements.  The
Lessee shall make such payments to the Lessor within five (5) days from the date
of receipt by the Lessor of a request for payment from the Lessee, provided that
the Lessee shall not make any such request more frequently than every two (2)
weeks.

     4.   Term.

     The Lessee shall hold the Leased Premises for a term of five (5) lease
years, beginning upon the Commencement Date and ending on November 30, 2001.
The phrase "lease year" as used herein shall mean a period of twelve (12)
consecutive calendar months.

     5.   Rent.

          (a) The Lessor and the Lessee agree that the annual rent payable by
the Lessee during the term of this Lease shall be Thirty-Two Thousand Five
Hundred Sixty-Five ($32,565.00) Dollars, which is an amount equal to the product
of Thirteen ($13.00) Dollars times 2,505, the total number of rentable square
feet of space included within the Leased Premises.

          (b) The annual rent payable by the Lessee to the Lessor pursuant to
Paragraph 5(a) above shall be payable in equal monthly installments at the
office of the Lessor or of the Lessor's agent, in advance, upon the first day of
each calendar month during the term of this Lease.

          (c) The Lessee agrees to pay the rent provided for in this Lease as
and when due including any additional rent, as well as all sums of money,
charges or other amounts required to be paid by the Lessee to the Lessor or to
another person designated by the Lessor under this Lease, all of which shall be
deemed to be "rent" in addition to the rent expressly provided for herein. All
payments of rent and additional rent shall be due and payable without demand
therefor unless otherwise expressly provided in this Lease. Nonpayment of
additional rent when due shall constitute a default under this Lease to the same
extent, and shall entitle the Lessor to the same remedies, as nonpayment of
rent.

                                      -4-

Proportionate Share, as hereinafter defined, of any increase in "operating
expenses" for the Building and the common areas of the Project attributable to
the Building, as identified on Exhibit B (the "Building Common Areas") over the

Lessee agree that the Lessee's proportionate share of operating expenses for
purposes of this Paragraph 6(a) and real estate taxes for purposes of Paragraph
6(b) below shall be 12.91 percent.  Operating expenses shall include all
charges, costs and expenses incurred by the Lessor in connection with the
operation, maintenance and repair of the Building and the Building Common Areas,
including without limitation (i) the cost of maintenance, electricity and heat
for the common areas of the Building and the Building Common Areas; (ii) the

calendar year during the term of this Lease the Lessor shall furnish to the
Lessee the Lessor's calculation of the amount of operating expenses during the
immediately preceding calendar year and the Lessee's share of such operating
expenses. The Lessor's calculations shall be conclusive and binding upon the
Lessee in the event that the Lessee fails to object to such calculations within
one hundred eighty (180) days following the receipt by the Lessee of the
Lessor's calculations, specifying with reasonable specificity in any such
objection the reason or reasons why the Lessee objects to the Lessor's
calculations. The Lessor and the Lessee agree that during the one hundred eighty
(180) day period following the date of delivery by the Lessor to the Lessee of
the Lessor's calculation of the amount of operating expenses during the
immediately preceding calendar year and the Lessee's share of such operating
expenses, the Lessee and its authorized representatives shall have the right to
review the Lessor's books and records relating to the calculation of the
Lessor's operating expenses at any reasonable time upon reasonable prior notice
thereof.

          (b) The Lessee shall pay to the Lessor as additional rent the Lessee's
Proportionate Share of any increase in real estate taxes levied against the
Building over the real estate taxes payable during the 1996 fiscal tax year
ending June 30, 1996.

          (c) The Lessee shall pay to the Lessor as additional rent monthly in
advance, an amount equal to one-twelfth (1/12) of Lessee's proportionate share
of increases in operating expenses and real estate taxes as reasonably estimated
by the Lessor in accordance with Paragraphs 6(a) and (b) above.  In the event
that the additional rent paid by 

                                      -6-
<PAGE>
 
the Lessee as the Lessee's proportionate share of operating expenses and real
estate taxes based on the Lessor's estimates is greater or less than the amount
actually due (the "Difference") either the Lessor shall pay the Lessee the
Difference, or the Lessee shall pay the Lessor the Difference, each within
thirty (30) days after the receipt of a request therefor, as appropriate.

          (d) The additional rent payments described in this Paragraph 6 shall
be prorated in the event that this Lease commences or terminates before the end
of any calendar year or fiscal tax year.

     7.   Condition of Leased Premises, Improvements, Maintenance and Repairs;
          Surrender.

          (a) The Lessor has not made and the Lessee has not relied upon any
representations or warranties, whether express or implied, as to the condition
of the Leased Premises or their suitability for the Lessee's use other than
those which may be specifically set forth in this Lease.  The Lessee accepts the
Leased Premises in the condition existing upon the date of execution of this
Lease except for latent defects.

          (b) The Lessor agrees that during the term of this Lease it shall, at
its own expense, make all necessary structural repairs and replacements to the
Leased Premises and the Building and it shall maintain the concealed plumbing,
concealed electrical and air conditioning and heating systems which are
installed or furnished by the Lessor except as otherwise expressly provided
herein or unless necessitated by the negligent or tortious acts of the Lessee,
its agents, servants, employees, invitees or licensees, with damage by fire or
other casualty excepted.  The Lessor assumes limited responsibility for the
replacement of mechanical equipment when, in its reasonable judgment, repairs
cannot be made in a reasonable manner or at a reasonable cost.  The Lessor shall
not be obligated to make any 

                                      -7-
<PAGE>
 
such repairs until the expiration of a reasonable period of time after its
receipt of verbal or written notice from the Lessee that such repairs are
required. Notwithstanding the foregoing, however, the Lessor shall use
reasonable efforts to repair immediately any equipment or other condition that
the Lessor is required to repair pursuant to this Lease to the extent that the
Lessor's failure to repair any such equipment or other condition substantially
impairs the use and enjoyment by the Lessee of the Leased Premises. The Lessor
shall be responsible for the reasonable removal of snow and ice and shall clean
and maintain the Project's common areas, including all landscaped areas and all
parking areas, and shall keep them reasonably illuminated throughout all periods
of darkness.

          (c) The Lessee agrees that during the term of this Lease it shall, at
all times, keep the Leased Premises in a good, clean condition and in good order
and repair and it shall make all necessary repairs and perform all necessary
maintenance for such purposes, except to the extent that the Lessor is required
to make any such repairs or provide any maintenance as described in this
Paragraph 7 and in Paragraphs 8, 16 and 17 of this Lease. The Lessee shall be
responsible for all necessary repairs, replacements and maintenance of all
interior glass, floors and walls within or part of the Leased Premises.  If the
Lessee fails, refuses or neglects to make such repairs or fails to prosecute
diligently such repairs to completion within thirty (30) days after written
notice from the Lessor of the necessity therefor, the Lessor may make such
repairs at the expense of the Lessee, and such expenses shall be collectible as
additional rent.  The Lessee shall not permit the Leased Premises to be
overloaded, damaged, stripped or defaced, nor suffer any waste.

          (d) The Lessor shall not be liable for any injury to or interference
with the Lessee's business arising from or caused by the Lessor's reasonably
making any repairs, alterations, additions or improvements in or to the Leased
Premises or the Building or to any 

                                      -8-
<PAGE>
 
appurtenances thereto or equipment therein. The Lessor agrees to use reasonable
efforts to minimize any interference with the Lessee's business in connection
with the making of any such repairs, alterations, additions or improvements in
or to the Leased Premises or the Building. There shall be no abatement of rent
because of such repairs, alterations, additions or improvements, except as
otherwise expressly provided herein. The Lessor agrees that if the Leased
Premises are rendered substantially untenantable as a result of or in connection
with the making of any such repairs, alterations, additions or improvements by
the Lessor for a period of five (5) consecutive business days the rent payable
by the Lessee shall be abated for the remainder of any such period during which
the Leased Premises are rendered substantially untenantable.

          (e) The Lessee shall, at the end of the term of this Lease or upon the
earlier termination of this Lease, surrender the Leased Premises to the Lessor,
together with all signs and all alterations, additions and improvements thereto,
in broom clean condition and in good order and repair except for ordinary wear
and tear and damage for which the Lessee is not obligated to make repairs under
this Lease.  The Lessee shall have the right at the end of the term hereof to
remove any equipment, furniture, trade fixtures, telephone system and security
systems or other personal property placed in the Leased Premises by the Lessee,
and the Lessee shall promptly repair any damage to the Leased Premises caused by
such removal and restore the Leased Premises to the condition existing upon the
date of execution of this Lease, reasonable wear and tear excepted.  In the
event that the Lessee fails to repair and restore the Leased Premises as
provided herein, the Lessor may perform or cause such repairs and restoration to
be performed at the Lessee's expense.  In the event of the Lessee's failure to
remove any of the Lessee's property from the Leased Premises, the Lessor is
hereby authorized, without liability to the Lessee for loss or damage thereto,
and at the sole risk of 

                                      -9-
<PAGE>
 
the Lessee, to remove and store any of the property at the Lessee's expense, or
to retain same under the Lessor's control or to sell at public or private sale,
any or all of the property not so removed and to apply the net proceeds of such
sale to the payment of any sum due hereunder, or to destroy such property. The
Lessor shall provide the Lessee with written or verbal notice twenty-four (24)
hours prior to taking any of the actions described in this Paragraph 7(e) with
respect to the Lessee's property.

     8.   Building Services.

          (a) The Lessor shall provide the following services and facilities:

               (i)   Air conditioning, ventilation and heating, through the air
                     conditioning and heating systems of the Building, in
                     amounts generally agreed upon as sufficient in first class
                     office Building, on business days Monday through Friday
                     from 8:00 a.m. to 8:00 p.m., and on Saturdays from 8:00
                     a.m. to 1:00 p.m. The Lessee agrees to cooperate fully with
                     the Lessor and to abide by all the regulations and
                     requirements which the Lessor may reasonably prescribe for
                     the proper functioning and protection of the air
                     conditioning and heating systems;

               (ii)  Electric current for Building standard level of
                     illumination using fixtures acceptable to the Lessor and
                     all other purposes requiring electricity. The Lessee agrees
                     that the Lessee shall be responsible for the replacement of
                     all light bulbs, globes, fluorescent tubes and ballast with
                     respect to all light fixtures located within the Leased
                     Premises, regardless of whether or not such light fixtures
                     are installed by the Lessor or the Lessee. The Lessor's
                     obligation to furnish electricity for lighting does not,
                     however, include electricity for reproduction machinery,
                     other than normal 110 volt, 30 amp circuits. Such
                     additional electrical service will be furnished, if
                     reasonably available, upon the payment by the Lessee of all
                     costs of installation, including wiring and separate
                     metering, and agreeing in writing to pay the costs of
                     current as additional rent;

               (iii) Maintenance and service of the public lavatories in the
                     Building;

               (iv)  Cleaning and maintenance of the Leased Premises and the
                     common areas in the Building. The cleaning and maintenance
                     services to be provided by the Lessor with respect to the
                     Leased 

                                      -10-
<PAGE>
 
                     Premises are more particularly described upon Exhibit C,
                     which is attached hereto and made a part hereof. The Lessor
                     agrees to maintain the common areas in the Building in a
                     condition consistent with a first class office building;

               (v)   Hot and cold water for lavatories, air conditioning and
                     sinks within the Leased Premises. If the Lessee requires
                     water for additional purposes the Lessee shall pay the cost
                     thereof as shown on a meter to be installed and maintained
                     at the Lessee's expense to measure such consumption;

               (vi)  Elevator service and maintenance; and

               (vii) Parking lot and landscape maintenance, including snow
                     removal from the Permitted Parking Areas and related
                     walkways.

     (b)  The Lessor shall not be liable in damages or otherwise for any delay
or failure in furnishing any of the foregoing services or facilities where such
delay or failure is excusable pursuant to the provision of Paragraph 27 hereof.
In no event shall such delay or failure, regardless of cause, constitute an
eviction of the Lessee, termination of this Lease or other interference with the
Lessee's use and enjoyment of the Leased Premises, provided that such delay or
failure is excusable pursuant to Paragraph 27 below.

     9.   Indemnity and Liability Insurance.

          (a) The Lessee agrees that, unless caused by the negligent or tortious
acts or omissions of the Lessor, its agents, servants or employees, it will:
(1) indemnify the Lessor against any injury, loss, claim or damage to any person
or property, wherever located, if caused by the negligent or tortious acts or
omissions of the Lessee or its agents or servants; and (2) without limiting the
generality of the foregoing, the Lessee specifically agrees that it will not
make any claims against the Lessor based on the leakage of water, gas or other
substance from any pipes, sprinklers or equipment, or by reason of the
existence, use or misuse of water or plumbing, heating, electrical, gas or other
fixtures or equipment, unless due to the negligence of the Lessor.

                                      -11-
<PAGE>
 
     If the Lessor shall, without fault on its part, be made a party to any
litigation commenced by or against the Lessee, the Lessee shall protect and hold
the Lessor harmless and indemnified from and against any loss or damage
sustained by the Lessor as a result thereof, and the Lessee shall pay all costs
and expenses, including reasonable attorneys' fees, incurred or paid by the
Lessor in connection with such litigation.  The Lessor agrees that the Lessee
shall have the right to select counsel to defend the Lessor for purposes of this
paragraph, provided that any such counsel is reasonably acceptable to the
Lessor.  The Lessor agrees that counsel approved by the Lessee's insurer shall
be acceptable to the Lessor for purposes of this Paragraph.

     (b) The Lessee shall procure and maintain in full force a "Comprehensive
Commercial Liability" insurance policy under which the Lessor shall be named as
an Additional Insured. Under such policy Bodily Injury limits shall not be less
than $2,000,000 per person, per occurrence and property damage limits shall not
be less than $500,000 each occurrence.  Certificates of the insurance affected
under this paragraph, and certificates of any and all renewals or replacements
of this policy, shall be delivered to the Lessor as soon as possible after the
effective date of this Lease.  The policy or certificate shall provide that the
insurance shall not be cancelled or reduced in amounts of limits, or reduced in
breadth of coverage without ten (10) days' prior written notice to the Lessor,
and that no act or omission on the part of the Lessee shall invalidate such
policies as they apply to the Lessor.

     10.  Compliance with Law.

     The Lessee agrees that it shall, at its own expense, comply with all state
and federal statutes, municipal regulations, and all regulations and orders of
any public authority (the "Governmental Requirements") with respect to the use
and occupancy of the Leased Premises or with respect to such improvements,
alterations or repairs of the Leased Premises by the 

                                      -12-
<PAGE>
 
Lessee as may be required to comply therewith. The Lessee specifically agrees
that if any improvements, alterations or repairs are required by the
Governmental Requirements as a direct result of the Lessee's use of the Leased
Premises the Lessee shall make all such improvements, alterations or repairs, at
its sole cost and expense. The Lessor represents and warrants to the Lessee that
to the best knowledge of the Lessor the Leased Premises and the use of the
Leased Premises by the Lessee comply with the Governmental Requirements as of
the date of this Lease. The Lessor agrees that the Lessee shall not have any
obligation pursuant to this Lease with respect to the compliance of the Building
Common Areas with the Governmental Requirements.

     11.  Assignment and Sublease.

     The Lessee shall not assign this Lease or make any sublease for the whole
or any part of the Leased Premises to any entity, without the prior written
consent of the Lessor, which shall not be unreasonably withheld or delayed.  The
Lessee agrees to give the Lessor written notice of any such assignment or
sublease within thirty (30) days after the effective date thereof.  The Lessor
and the Lessee agree that in the event of any assignment or sublease to a
person, firm or entity that is approved by the Lessor pursuant to Paragraph 11
of this Lease, the Lessor shall be entitled to collect and the Lessee shall pay
to the Lessor promptly following its receipt from any such assignee or subtenant
fifty (50%) percent of all payments of rent, additional rent or other charges
payable by any such assignee or subtenant in excess of the rent, additional rent
and other charges payable by the Lessee pursuant to the terms of this Lease.
The Lessee shall include in its request for the Lessor's consent to any proposed
assignment or sublease a reasonably detailed summary of the terms of any such
proposed assignment or sublease.  If this Lease is assigned or if the Leased
Premises or any part thereof are occupied by anybody other than the Lessee, the
Lessor may collect rent from the 

                                      -13-
<PAGE>
 
assignee or occupant and apply the net amount collected to the rent reserved,
but no such assignment, underletting, occupancy or collection shall be deemed a
waiver of this provision or the acceptance of the assignee, undertenant or
occupant as lessee. Nothing herein contained shall relieve the Lessee from its
covenants and obligations for the term of this Lease. The Lessee agrees to
reimburse the Lessor for the Lessor's reasonable attorneys' fees incurred in
conjunction with the processing and documentation of any such requested
transfer, assignment, subletting, license or concession agreement, change of
ownership, mortgage or hypothecation of this Lease or the Lessee's interest in
and to the Leased Premises, excluding any attorneys' fees incurred by the Lessor
in connection with the review by the Lessor of the form of any proposed sublease
by the Lessee.

     12.  Alterations and Additions.

     The Lessee shall not make any alterations or additions to the Leased
Premises without the prior written consent of the Lessor, which shall not be
unreasonably withheld or delayed. Notwithstanding anything contained herein to
the contrary, the Lessor's prior consent shall not be required with respect to
any nonstructural alteration which does not affect the Building systems or any
other part of the Building (other than the Leased Premises), provided that the
estimated cost of the labor and materials for any such alteration or alterations
shall not exceed Ten Thousand ($10,000.00) Dollars in the aggregate within any
twelve (12) month period during the term of this Lease.  The Lessor and the
Lessee agree that the Lessor may, in its discretion, condition its approval of
any alterations or additions proposed to be made by the Lessee to the Leased
Premises upon the Lessee agreeing to restore the Leased Premises to the
condition existing prior to the installation of any alterations or additions, at
the Lessee's sole cost and expense, upon the expiration of the term 

                                      -14-
<PAGE>
 
of this Lease. The Lessor expressly reserves the right to make its own
alterations, additions or improvements to the Building.

     13.  Fire Insurance.

     The Lessor shall carry fire insurance with extended coverage on the
Building in an amount not less than the full insurable value of the Building,
exclusive of the foundations. The Lessee shall carry fire insurance with
extended coverage on all of the Lessee's fixtures, furniture, furnishings,
equipment and stock in trade to the extent of their full replacement value. Fire
insurance will be carried with companies qualified to do business in
Massachusetts, and the Lessee agrees to furnish the Lessor with certificates
evidencing such insurance upon the request of the Lessor therefor.  The Lessee
also agrees that all such insurance policies shall provide that they shall not
be cancelled or materially changed without at least ten (10) days' prior written
notice thereof to the Lessor and that no act or omission by the Lessee shall
invalidate such policies as they apply to the Lessor.

     14.  Access by Lessor.

     The Lessor shall have the right to enter the Leased Premises at reasonable
times during the Lessee's business hours for the purpose of inspection, making
such repairs as the Lessor may be obligated to make or may reasonably deem
necessary for curing any default of the Lessee.  The Lessor agrees that, except
in the event of an emergency, it shall provide the Lessor with twenty-four (24)
hours' prior notice of any exercise by the Lessor of the right of entry reserved
hereby.  The Lessor shall have the right of access to the Leased Premises at any
time in the event of an emergency, without prior notice, without liability to
the Lessee and without such entry constituting an eviction of the Lessee or
termination of the Lease. The Lessor agrees to use reasonable efforts to
minimize any interference with the Lessee's business in connection with the
exercise by the Lessor of the right of access reserved hereby.

                                      -15-
<PAGE>
 
     15.  Utilities.

     The Lessor agrees to provide and pay for electricity, heat and air
conditioning used or consumed by the Lessee in connection with its use and
occupancy of the Leased Premises during the entire term of this Lease, subject
to the Lessee's obligation to pay additional rent for increases in Operating
Expenses pursuant to Paragraph 6(a) above.  The Lessee agrees to take reasonable
steps to conserve energy during the entire term of this Lease.

     16.  Destruction of Leased Premises.

          (a) If the Leased Premises are damaged by fire, the elements,
unavoidable accident or other casualty, but are not thereby rendered
untenantable in whole or in part, the Lessor shall at its own expense cause such
damage to be repaired within one hundred fifty (150) days from the occurrence
thereof, or within such longer period of time as may be required exercising due
diligence, and the rent shall not be abated.  If by reason of such occurrence,
the Leased Premises are rendered untenantable only in part, the Lessor shall at
its own expense cause the damage to be repaired within one hundred fifty (150)
days from the occurrence thereof, and the rent shall be abated proportionately
as to the portion of the Leased Premises rendered untenantable.  If the Leased
Premises are rendered wholly untenantable, the Lessor shall at its own expense
cause such damage to be repaired as soon as practicable and the rent shall abate
until the Leased Premises have been restored and rendered tenantable, or the
Lessor or the Lessee may, at their election, terminate this Lease and the
tenancy hereby created by giving to the other, within the thirty (30) days
following the date of such occurrence, written notice of their election to
terminate this Lease and in that event the rent shall be adjusted as of the date
of such occurrence.

          (b) In the event that fifty (50%) percent or more of the rentable area
of the Leased Premises is damaged or destroyed the Lessor may terminate this
Lease and the 

                                      -16-
<PAGE>
 
tenancy hereby created by giving the Lessee ninety (90) days' prior written
notice of the Lessor's election to so terminate this Lease, with such notice
given, if at all, within the ninety (90) days following the date of said
occurrence. Rent shall be adjusted as of the effective date of such termination.
In the event that the Lessor does not exercise the right of termination set
forth herein the Lessor shall cause the damage to be repaired and rent shall be
abated as provided in Paragraph 16(a) above.

     17.  Eminent Domain.

          (a) If the whole of the Leased Premises or the Building are acquired
or condemned by eminent domain for any public or quasi-public use or purpose,
then the term of this Lease shall cease and terminate as of the date of title
vesting in such proceeding, all rentals shall be paid up to that date and the
Lessee shall have no claim against the Lessor or the condemning authority for
the value of any unexpired term of this Lease.

          (b) If any part of the Leased Premises or the Building is acquired or
condemned as aforesaid, and in the event that such partial taking or
condemnation shall render the Leased Premises unsuitable for the business of the
Lessee, as reasonably determined by the Lessee, then the term of this Lease
shall cease and terminate as of the date of title vesting in such proceeding.
The Lessee shall have no claim against the Lessor or the condemning authority
for the value of any unexpired term of this Lease and rent shall be adjusted to
the date of such termination. In the event of a partial taking or condemnation
which is not extensive enough to render the Leased Premises unsuitable for the
business of the Lessee, as reasonably determined by the Lessee, then the Lessor
shall promptly restore the Leased Premises to a condition comparable to its
condition at the time of such condemnation less the portion lost in the taking,
and this Lease shall continue in full force 

                                      -17-
<PAGE>
 
and effect with a proportionate reduction in rent and additional rent based upon
the nature and extent of any such taking.

          (c) In the event of any condemnation or taking as aforesaid, whether
whole or partial, the Lessee shall not be entitled to any part of the award paid
for such condemnation and the Lessor shall receive the full amount of such
award.  The Lessee hereby expressly waives any right to claim any part thereof.

          (d) Although all damages in the event of any condemnation are to
belong to the Lessor regardless of whether such damages are awarded as
compensation for diminution in value of the leasehold or to the fee of the
Leased Premises, the Lessee shall have the right to claim and recover from the
condemning authority, but not from the Lessor, such compensation as may be
separately awarded or recoverable by the Lessee in the Lessee's own right on
account of any and all damage to the Lessee's business by reason of the
condemnation and for or on account of any relocation allowance or any other cost
or loss to which the Lessee might be put in removing the Lessee's merchandise,
furniture, fixtures, leasehold improvements and equipment.

     18.  Lessee's Default.

     The occurrence of any of the following shall constitute an event of default
and breach of this Lease by the Lessee:

          (a) The vacation or abandonment of the Leased Premises by the Lessee
or the failure of the Lessee to continue in its regular business on a day-to-day
basis during the term of this Lease, subject to the Lessee's rights pursuant to
Paragraph 33(c) below;

          (b) The failure of the Lessee to pay, within ten (10) days of the date

any of the foregoing.

                                      -18-
<PAGE>
 
          (c) The failure of the Lessee to observe or perform any other
provisions, covenants or obligations of this Lease to be observed or performed
by the Lessee, where such failure continues for thirty (30) days after the
receipt by the Lessee of written notice thereof from the Lessor, unless the
Lessee begins promptly after the receipt of written notice thereof from the
Lessor to cure any such default and proceeds diligently and conscientiously to
cure such default; or

          (d) The making by the Lessee of any assignment for the benefit of
creditors; the adjudication that the Lessee is bankrupt, insolvent or unable to
pay its debts; the filing by or against the Lessee of a petition to have the
Lessee adjudged a bankrupt or a petition for reorganization or arrangement under
any law relating to bankruptcy unless, in the case of a petition filed against
the Lessee, such petition is dismissed within sixty (60) days after the filing
thereof; the appointment of a trustee or receiver to take possession of
substantially all of the Lessee's assets located in the Leased Premises or of
the Lessee's interest in this Lease, unless possession is restored to the Lessee
within thirty (30) days after such appointment; or the attachment, execution or
levy against, or other judicial seizure of, substantially all of the Lessee's
assets located in the Leased Premises or of the Lessee's interest in this Lease,
unless discharged within thirty (30) days after issuance thereof.

     19.  Lessor's Remedies.

     Upon the occurrence of any event of default as described in Paragraph 18:

          (a) The Lessor may perform for the account of the Lessee any
obligation with respect to which the Lessee is in default and immediately
recover as additional rent any expenditures made and the amount of any
obligations incurred in connection therewith plus interest at the Prime Rate
published in The Wall Street Journal plus three (3%) percent per 

                                      -19-
<PAGE>
 
annum for such expenditures from the date of any such expenditures, together
with a late charge for payments of rent past due at the same rate of interest;

          (b) The Lessor may accelerate all rent and additional rent due for the
balance of the term of this Lease and declare all such rent to be immediately
due and payable;

          (c) The Lessor, at its option, may serve notice upon the Lessee that
this Lease and the then unexpired term hereof shall cease and expire and become
absolutely void on the date specified in such notice, which shall be not less
than five (5) days after the date of such notice without any right on the part
of the Lessee to save forfeiture by payment of any sum due or by the performance
of any term, provision, covenant, agreement or condition broken.  This Lease and
the term hereof, as well as the right, title and interest of the Lessee
hereunder shall, upon the effective date of such notice, wholly cease and expire
and become void in the same manner and with the same force and effect, except as
to the Lessee's liability, as if the date fixed in such notice were the date
provided herein for the expiration of the term of this Lease.  Thereupon the
Lessee shall immediately quit and surrender to the Lessor the Leased Premises
and in any event, the Lessor may forcefully remove the property of the Lessee
without being liable either in damages or in a criminal prosecution.  No such
expiration or termination of this Lease shall relieve the Lessee of its
liability and obligations under this Lease, whether or not the Leased Premises
shall be relet. If the Lessee fails to remove any equipment, furniture, trade
fixtures or other property prior to any such repossession by the Lessor such
equipment, furniture, fixtures and other property shall be deemed abandoned by
the Lessee and shall become the property of the Lessor;

          (d) The Lessor may, at any time after written notice of the occurrence
of any event of default and the expiration of any applicable cure and/or notice
periods, re-enter 

                                      -20-
<PAGE>
 
and repossess the Leased Premises or any part thereof and attempt, in its own
name as agent for the Lessee if this Lease has not been terminated or on its own
behalf if this Lease has been terminated, to relet all or any part of such
Leased Premises for and upon such terms and to such persons, firm or corporation
and for such period or periods as the Lessor, in its sole discretion, shall
determine, including a term beyond the termination of this Lease. The Lessor
shall not be required to accept any tenant offered by the Lessee or observe any
instruction given by the Lessee with respect to such reletting. The cost of
reasonable brokerage and legal fees expended by the Lessor in connection with
the reletting of the Leased Premises as well as the reasonable cost of repairing
or restoring the Leased Premises arising out of damage caused by the Lessee or
improvements made by the Lessee to the Leased Premises that the Lessee is
required to remove pursuant to this Lease and failed to remove shall be charged
to and be payable by the Lessee as additional rent hereunder, and any sums
collected by the Lessor from any new tenant shall be credited against the
balance of the rent due hereunder for the remainder of the term of this Lease.
The Lessee shall pay to the Lessor monthly, on the date when the rent would have
been payable under this Lease, the amount of rent and additional rent due
hereunder less the amount obtained by the Lessor from any such new tenant; and

          (e) The rights and remedies given to the Lessor in this Lease are
distinct, separate and cumulative remedies, and no one of them, whether or not
exercised by the Lessor, shall be deemed in exclusion of any of the others.

     20.  Signs and Advertising.

     The Lessee agrees that it shall not erect, install or otherwise display any
signs, displays, advertisements or other means of identifying the Leased
Premises and the products and services available therein to the public on the
Leased Premises, or the Building without 

                                      -21-
<PAGE>
 
the prior written consent of the Lessor, which shall not be unreasonably
withheld or delayed. All signs erected or installed by the Lessee in accordance
with this Paragraph 20 shall be removed by the Lessee at its expense upon the
expiration of the initial or any extended term of this Lease and the Lessee
shall repair any damage caused by any such removal at the time that the Lessee
removes any such sign or signs.

     21.  Rules and Regulations.

     The Lessor shall have the right to make such reasonable rules and
regulations as, in the judgment of the Lessor are advisable for the safety, care
and preservation of the Leased Premises, the Building and the Project (the
"Rules and Regulations").  The Rules and Regulations shall be deemed to be
covenants of this Lease running with the land and any breach or violation
thereof shall be deemed a breach or default hereunder, subject to the thirty
(30) day notice required pursuant to Paragraph 18(c) above and subject to the
requirement that the Lessor deliver to the Lessee a written copy of the Rules
and Regulations at least fifteen (15) days prior to the date when the Rules and
Regulations shall be applicable to the Lessee's use and occupancy of the Leased
Premises.  The Lessor agree to enforce the Rules and Regulations in a non-
discriminatory manner with respect to all tenants occupying any portion of the
Project.

     22.  Mutual Subrogation Waiver.

     The Lessor and the Lessee agree that any claim by either of them against
the other for damages arising out of any peril, insured under any property
damage or earnings policy carried by either shall not be assignable, nor the
subject of a subrogation action by any third party.  Each of the parties agrees
to release the other party from any and all liability for damages for any claim
or claims arising out of any peril insured under any property damage or earnings
policy carried by either the Lessor or the Lessee.

                                      -22-
<PAGE>
 
     23.  Notice of Claims.

     In the event that any claim, cause of action or suit is made or brought
against the Lessee, or the Lessor, of which the Lessee shall have knowledge,
arising from the occupancy of the Lessee of or pertaining to the Leased
Premises, the Lessee shall immediately notify the Lessor thereof in writing.  In
the event that any claim, cause of action or suit is made or brought against the
Lessor, or the Lessee, of which the Lessor shall have knowledge, arising from
the occupancy of the Lessee of or pertaining to the Leased Premises, the Lessor
shall immediately notify the Lessee thereof in writing.

     24.  Quiet Enjoyment.

     The Lessor covenants and agrees that upon the Lessee's paying the rent
herein reserved and performing and observing all the other covenants to be
performed and observed on the part of the Lessee, the Lessee may use and occupy
the Leased Premises throughout the full term of this Lease and any renewals or
extensions thereof without any disturbance by any person whatsoever.

     25.  Subordination and Attornment.

     The Lessee accepts this Lease subject and subordinate to any mortgage or
mortgages, including without limitation the notes or other obligations secured
thereby and any and all renewals, modifications, consolidations, replacements or
extensions of any such mortgages or the notes or other obligations secured
thereby, any easement or restriction of record now in existence or hereafter
made from time to time, affecting the fee title or the leasehold estate to the
Building or premises which the Leased Premises are a part or any part thereof of
the Lessor's interest therein.  The Lessee also accepts this Lease subject and
subordinate to all instruments in the chain of fee title, including any and all
renewals, modifications, consolidations, replacements or extensions of such
instruments.  The Lessee shall execute, 

                                      -23-
<PAGE>
 
acknowledge and deliver to the holder of any such mortgage or to any of the
parties to such instruments, at any time upon demand by such holder or by any
such party, any release, certificates or other documents that may be required by
such holder or by any such party, for the purpose of evidencing the
subordination of this Lease to such mortgages or other instruments or to any
renewals, modifications, consolidations, replacements or extensions thereof. The
Lessor is authorized to execute any such documents as the Lessee's attorney-in-
fact if the Lessee fails or refuses to execute any such instruments or documents
within ten (10) days following the request of the Lessor therefor unless the
Lessee's failure or refusal is reasonable taking into account the circumstances
that exist at the time of any such request. In the event of a sale under any
mortgage or any note or other obligations secured thereby, to which this Lease
is subordinate, or a taking of possession of the Leased Premises by the
Mortgagee or other person acting for or through the Mortgagee under any mortgage
to which this Lease is subordinate, the Lessee agrees that it shall attorn to
and recognize as the Lessor hereunder the party who, but for this Lease, would
be entitled to possession of the Leased Premises, provided that any such party
recognizes this Lease and the Lessee's rights hereunder.

     26.  Estoppel Certificates.

     The Lessee and the Lessor shall, at any time and from time to time, within
twenty (20) days following its receipt of a written request from the other party
or any mortgagee, execute, acknowledge and deliver to such other party or
mortgagee a written statement certifying that this Lease is in full force and
effect and unmodified or, if modified, stating the nature of such modification,
certifying the date to which the rent reserved hereunder has been paid, and
certifying that there are not, to the knowledge of the party signing such
statement, any uncured defaults on the part of the other party or specifying
such defaults if 

                                      -24-
<PAGE>
 
any are claimed. Any such statement may be relied upon by any prospective
purchaser or mortgagee of all or any part of the Building or real property on
which the Building is located. The failure of the Lessor or the Lessee to
deliver such statement within such twenty (20) day period shall be conclusive
upon the other party that this Lease is in full force and effect and unmodified,
and that there have not been made any advance payments of rent except that may
have been made as security hereunder and that there are no uncured defaults with
respect to the other party's performance hereunder.

     27.  Unforeseen Delay.

     The provisions of this paragraph shall be applicable if there shall occur,
during the term hereof, or any renewal or extension thereof, any strike,
lockout, or labor dispute; inability to obtain labor or materials or reasonable
substitute thereof; inability in obtaining fuel, electricity, services or
supplies from the sources from which they are normally obtained or from
reasonably comparable substitute sources; or act of God, governmental
restriction, regulation, or control, enemy or hostile governmental action, civil
commotion, insurrection, revolution, sabotage, or fire or other casualty or any
other condition or cause beyond the reasonable control of the Lessor. If the
Lessor shall, as the result of any such event, fail reasonably to perform any
obligation required hereunder, then such obligation shall be reasonably
performed as soon as practicable after such event abates.  If the Lessor shall,
as a result of such event, be unable to exercise any right or option within any
time limit provided thereof or in this Lease, such time limit shall be deemed
extended for a period equal to the duration of such event.

     28.  Holding Over.

     If the Lessee retains possession of the Leased Premises or any part thereof
after the termination of the term, the Lessee shall pay the Lessor rent at one
and one-half (1 1/2) times 

                                      -25-
<PAGE>
 
the monthly rate specified herein as the last month of the term hereof for the
time the Lessee remains in possession. The provisions of this paragraph do not
exclude the Lessor's right to summary process or any other rights hereunder. The
Lessee shall indemnify and hold the Lessor harmless from and against any and all
loss or liability resulting from the failure of the Lessee to surrender
possession of the Leased Premises in accordance with the term and conditions of
this Lease.

     29.  Brokers.

     The Lessor and the Lessee hereby represent and warrant to each other that
no broker's commission or finder's fee is due in connection with the
consummation of this transaction except a broker's fee due to Colebrook Realty
Services, Inc. and R. J. Greeley & Company, L.L.C. (collectively, the "Broker"),
and that no real estate broker, agent or other third party has or will be
engaged to represent it in this transaction except the Broker. The Lessor shall
be responsible for the payment of all fees due the Broker arising out of this
transaction.

     30.  Waiver, Notices.

     No consent or waiver, express or implied by the Lessor to or of any breach
of any covenant, condition or duty of the Lessee shall be construed as a consent
or waiver to or of any other breach of the same or any other covenant, condition
or duty.  All notices, statements, demands, requests, consents, communications
and certificates from either party hereto to the other shall be made in writing
unless specified to the contrary herein and sent by certified mail, return
receipt requested, hand delivered or by Federal Express or similar overnight

     THIS LEASE is made and entered into as of the ______day of October, 1995,

by and between the MARYLAND STADIUM AUTHORITY, an instrumentality of the State

of Maryland ("Landlord") and PHYSICIANS QUALITY CARE, INC., a Delaware

corporation ("Tenant").

     In consideration of the rents hereinafter reserved and the agreements
hereinafter set forth, Landlord and Tenant mutually agree as follows:

     1.  SUMMARY OF TERMS.

     The following is a summary of the principal terms of the Lease.  Any
capitalized term set forth below shall, for the purposes of this Lease, have the
meaning ascribed to it in this Section 1.

     A.   Description of Premises

          (1) Building:  The northern portion of the Camden Yards Warehouse
Building located at 323 W. Camden Street, Baltimore, Maryland, being the

the 6th floor of the Building as shown on Schedule A.

     B.   Rent

          (1) Annual Basic Rent: The product of fifteen dollars ($15.00)
multiplied by the agreed rental area for purposes of rent calculation ("Agreed
Rental Area") of Two Thousand Two Hundred and Fifty (2,250) square feet.  The
Annual Basic Rent includes the Base PILOT and the Base Operating Costs.  The

      3.  LEASED PREMISES.

     Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord,
the Premises as shown on the plan attached hereto as Schedule A, together with
the non-exclusive easement, during the Term, for use of the Common Area and the
pedestrian walkways providing access to the Building.

     Tenant acknowledges that portions of the walkways surrounding the Building
constitute public right-of-way as well as part of the pedestrian access and
circulation system for the Oriole Park at Camden Yards and that during baseball
games, baseball-related events and events sponsored by Landlord, such walkways
shall be used by members of the public entering and leaving the Oriole Park at
Camden Yards.

      4.  TERM AND COMMENCEMENT OF TERM.

     4.1  Term.  The term of this Lease (the "Term") shall commence on the
earlier of:

          a.   the date on which Tenant shall take possession of all or any
portion of the Premises, for the purpose of commencing the operation of its
business therein, provided that such possession shall be only with the written
approval of the Landlord, which shall not be unreasonably withheld, or

          b.   fifteen (15) days following the date the Premises are Ready for
Occupancy, subject to further provisions of this Section 4.1, (the earlier of a
or b being hereinafter referred to as the "Lease Commencement Date") and shall
be for the period of time set forth in Section 1.D.(1), plus the part of the
month, if any, from the Lease Commencement Date to the first fill month of the
Term, unless earlier terminated pursuant to any other provision of this Lease or
pursuant to law.

     Notwithstanding anything contained in this Lease to the contrary, in the
event the Lease Commencement Date has not occurred by March 31.1995, this Lease
shall terminate and be of no further force and effect.

     4.1  Ready for Occupancy.  For purposes hereof, the Premises shall be
deemed conclusively ready for occupancy ("Ready for Occupancy") when Landlord
has substantially completed its work on the Tenant's Improvements.  Substantial
completion means that the Premises can be used for their intended purpose as
professional offices with only Punchlist Items not affecting use outstanding.

     4.2  Options to Renew.  Provided Tenant or an approved subtenant is in
possession of the Premises and an Event of Default does not exist under this
Lease, Tenant shall have one (1) option to renew the Term of this Lease for one
(1) additional period of five (5) years ("Renewal Term") to commence immediately
upon the expiration of the initial Term, or the immediately preceding Renewal
Term, as the case may be, upon the same terms, covenants and conditions as
contained in this Lease, except that (i) the rate of Annual Basic Rent payable
by Tenant during such Renewal Term shall be the amount agreed upon in writing by

                                       4
<PAGE>
 
Landlord and Tenant; which rate shall be based upon fair market rents of other
singular tenants at that time.

     In order to exercise the option granted herein, Tenant shall so notify
Landlord, in writing, not less than three (3) months prior to the expiration of
the initial Term, and if no such notice of exercise of the option is received,
the option shall be deemed waived.  In the event Tenant exercises its option,
Landlord and Tenant shall execute a modification to this Lease acknowledging
such renewal and setting forth the new Annual Basic Rent.

     An option shall be void if, at the time of exercise of such option, Tenant
or an approved subtenant is not in possession of the Premises, an Event of
Default exists under this Lease, or Tenant fails to deliver the requisite notice
thereof within the time period specified above.  The options granted herein
shall not be severed from this Lease, exercised collectively, or separately
sold, assigned or transferred.

      5.  TENANT IMPROVEMENTS AND ACCEPTANCE OF PREMISES.

     5.1  Base Building Improvements. Landlord shall, at its sole cost and
expense, provide the base building improvements ("Base Building Improvements")
described under the heading "Base Building Improvements" in the work letter
attached as Schedule C ("Work Letter").

     5.2  Tenant Improvements. Prior to the Lease Commencement Date, Landlord
shall make the improvements to the Premises described in the Plans and
Specifications to be developed under the heading "Tenant Improvements" ("Tenant
Improvements") in the Work Letter attached as Schedule C, in accordance with the
then-current Baltimore City building, health, fire, and other codes, rules and
ordinances applicable to office buildings in downtown Baltimore City regardless
of the applicability of such codes generally to real property owned by the State
of Maryland or its agencies or instrumentalities.  Landlord shall bear the cost
of the Tenant Improvements in an amount not to exceed Eighty-five Thousand
Dollars ($85,000.00).  Any cost in Tenant Improvements in excess of $85,000
shall be the sole responsibility of Tenant.

     Landlord and Tenant have agreed that Landlord shall finance the Tenant
Improvements ("Tenant Improvement Financing") in an amount not to exceed Eighty-
five Thousand Dollars ($85,000.00) at an interest rate of seven percent (7%) per
annum in accordance with the schedule for repayment attached hereto as Schedule
D. The Tenant Improvement Financing shall be secured by a letter of credit, in
an amount equal to the unamortized portion of the Tenant Improvement Financing,
which letter of credit shall be obtained by Tenant from a lender and on terms
satisfactory to Landlord.  The Tenant Improvement Financing shall be prepaid
upon the occurrence of an Event of Default under this Lease or in the event this
Lease is terminated and Landlord has not otherwise been paid the full
outstanding amount of the Tenant Improvement Financing from insurance proceeds
or taking awards.

     Landlord and Tenant acknowledge the desirability of limiting the costs of
the Tenant Improvements to $85,000 (the "Budget"), thereby limiting Tenant's
exposure for excess costs. 

                                       5
<PAGE>
 
Landlord and Tenant shall use all reasonable efforts to cause the architect
designing the Tenant Improvements to produce Plans and Specifications describing
Tenant Improvements which can be constructed within the Budget. Landlord shall
keep Tenant informed during the process of soliciting and reviewing bids from
contractors for performing the Tenant Improvements. In the event the contractor
submitting the best bid acceptable to both Landlord and Tenant estimates the
total cost of constructing the Tenant Improvements in accordance with the Plans
and Specifications to exceed the Budget, Landlord and Tenant shall cooperate in
good faith to reduce the total cost to Budget through value engineering. Tenant
covenants and agrees to promptly pay to Landlord upon receipt of invoice any
excess of the cost of Tenant Improvements over the Budget. If the cost of the
Tenant Improvements is less than the Budget, the Tenant Improvement Financing
shall be appropriately adjusted.

     5.3. Completion Schedule.  A schedule with time lines for completion of the
Base Building Improvements and Tenant Improvements is attached hereto as a part
of Schedule C and made a part hereof ("Completion Schedule").  Landlord and
Tenant shall use all reasonable efforts, and shall cause the architects,
designers and contractors to use all reasonable efforts, to adhere to the
Completion Schedule.

     5.4. Acceptance of Premises.  Landlord shall notice Tenant in writing at
least thirty (30) days prior to the date the Premises are expected to be Ready
for Occupancy so that Tenant may schedule its move to the Premises.  Within the
first ten (10) days after Landlord's notice, Landlord shall furnish Tenant with
a punchlist of items to be completed by Landlord ("Punchlist Items") and a
schedule for their completion, and shall make the Premises available for
inspection.  Tenant shall comment in writing upon the Punchlist Items and the
schedule within five (5) days following Landlord's submission, and in the
absence of such commentary within said five-day period Tenant shall be deemed to
have concurred with the Punchlist Items and schedule as submitted by Landlord.
Landlord and Tenant shall cooperate in good faith to resolve any disagreements
between them regarding the Punchlist Items and the schedule.  Occupancy of the
Premises by Tenant for the purpose of commencing operation of its business shall
be deemed to constitute acceptance of the Premises and acknowledgement by Tenant
that Landlord has fully complied with its obligations hereunder to construct and
deliver the Premises to Tenant, except the Punchlist Items, which shall be
completed by Landlord in accordance with the approved schedule. Landlord, its
agents, employees and contractors shall have the right to enter the Premises
before or after normal business hours, as set forth in Section 11, to complete
or repair any such Punchlist Items and such entry for such purpose shall not
constitute an actual or constructive eviction, in whole or in part, or entitle
Tenant to any abatement or diminution of rent or relieve Tenant of any of its
obligations under this Lease.

      6.  RENT.

     6.1. Annual Basic Rent.  Tenant shall pay to Landlord during each Rental
Year of the Term fixed rent equal to the Annual Basic Rent as set forth in
Section 1.B.(l).  Annual Basic Rent shall be payable in advance on the first day
of each month of the Term in equal monthly installments, without notice, demand,
abatement (except as otherwise specifically provided in this Lease), deduction
or set-off.  If the Term of this Lease shall commence on a day other than the
first day of a month, the first payment shall include any prorated Annual 

                                       6
<PAGE>
 
Basic Rent for the period from the Lease Commencement Date to the first day of
the first full calendar month of the Term.

     "Rental Year" shall mean each successive twelve (12) calendar month period
occurring during the Term of this Lease, or portion of such a period, with the
first Rental Year commencing as of the Lease Commencement Date and ending on the
last day of the twelfth full calendar month thereafter.  For any Rental Year of
less or more than twelve full months, Annual Basic Rent shall be adjusted
accordingly.  All Annual Basic Rent and Additional Rent shall be paid to
Landlord at the Landlord Payment Address.

     6.2. Additional Rent.  Tenant shall pay to Landlord as additional rent
("Additional Rent") all other sums of money which shall become due and payable
hereunder, including, but not limited to, the payment of the Tenant Improvement
Financing as set forth on Schedule D hereto and Monthly Parking Fees pursuant to
Section 12 hereof.  Unless a date for payment is otherwise specified herein, all
Additional Rent shall be due and payable within thirty (30) days of receipt of
invoice from Landlord.  Additional Rent shall be payable without notice, demand,
abatement (except as otherwise specifically provided in this Lease), deduction
or set-off.

     6.3. Late Charge.  If Tenant fails to make any payment of Annual Basic
Rent, Additional Rent, or other sums required to be paid hereunder on or before
the date when payment is due, Tenant shall pay to Landlord, as Additional Rent,
a late charge to cover extra administrative costs and loss of use of funds equal
to (a) two percent (2%) of the amount due for the first month or portion thereof
that such amount is past due plus (b) interest on the amount remaining unpaid
thereafter at the annual rate of two percent (2%) above the prime rate charged
by Citibank, N.A., as of the due date of such amount; provided, however, that
should such late charge at any time violate any applicable law, the late charge
shall be reduced to the highest rate permitted by law (the foregoing rate being
herein referred to as the "Default Rate"). Landlord's acceptance of any rent
after it has become due and payable shall not excuse any delays with respect to
future rental payments or constitute a waiver of any of Landlord's rights under
this Lease.

      7.  OPERATING COSTS; TAXES.

     7.1. Definitions.   For purposes of this Lease, the following definitions
shall apply:
          a.   "Base Operating Costs" has the meaning set forth in Section
l.C.(2).  In the second Rental Year, Operating Costs shall increase by three
percent (3%) of the Base Operating Costs and in subsequent Rental Years,
Operating Costs shall increase by three percent (3%) of the Operating Costs for
the immediately preceding Rental Year.  The annual increase in Operating Costs
over Base Operating Costs is hereinafter referred to as the "Operating Cost
Increase."

     The Base Operating Costs shall be adjusted at the beginning of each Renewal
Term to equal the actual Operating Costs incurred during the first Rental Year
during such Renewal Term.

                                       7
<PAGE>
 
          b.   "Fractional Share" shall be agreed upon by the Landlord and the
Tenant within ten (10) days of completion of the Tenant Improvements and shall
be based upon the proportion the Agreed Rental Area of the Premises bears to the
total rental area of the Building.

          c.   "Operating Costs" means all expenses and costs of every kind
and nature which Landlord shall pay or become obligated to pay because of or in
connection with operating, managing, painting, repairing, insuring and cleaning
the Building, including the Premises, the Common Area, and the pedestrian
walkways serving the Building, such costs including, but not limited to, the
following:

               (i) costs of all supplies and materials used, and labor charges
incurred, in the operation, maintenance, decoration, repairing and cleaning of
the Property, including janitorial service for all areas of the Building;

               (ii) cost of all equipment purchased or rented which is utilized
in the performance of Landlord's obligations hereunder, and the cost of
maintenance and operation of any such equipment;

               (iii) cost of all maintenance and service agreements for the
Property and the equipment therein, including, without limitation, alarm
service, security service, window cleaning, and elevator maintenance;

               (iv) accounting costs, including the cost of audits by certified
public accountants, outside legal and engineering fees and expenses incurred in
connection with the operation and management of the Property;

               (v) wages, salaries and related expenses of all on-site and off-
site agents or employees engaged in the operation, maintenance, security and
management of the Property;

               (vi) cost of all insurance coverage for the Property from time to
time maintained by Landlord, including but not limited to the costs of premiums
for commercially-obtained insurance or a self-insurance program with respect to
personal injury, bodily injury, including death, property damage, business
interruption, workmen's compensation insurance covering personnel and such other
insurance as Landlord shall deem necessary, which insurance Landlord may
maintain under policies covering other properties owned by Landlord in which
event the premium shall be reasonably allocated and documented by Landlord;

               (vii) cost of repairs, replacements, and general maintenance to
the Property, including without limitation the mechanical, electrical and
heating, ventilating and air conditioning equipment and/or systems;

               (viii) any and all Common Area maintenance, repair or
redecoration (including repainting) and exterior and interior landscaping;

                                       8
<PAGE>
 
          (ix) cost of removal of trash, rubbish, garbage and other refuse from
the Property as well as removal of ice and snow from the sidewalks on or
adjacent to the Property;

          (x)  all charges for electricity, gas, water, sewerage service,
heating, ventilation and air conditioning and other utilities furnished to the
Building (including legal, architectural and engineering fees incurred in
connection therewith);

          (xi)  amortization of capital improvements made to the Building after
the year of substantial completion of the Base Building Improvements, which
improvements were undertaken by Landlord with the reasonable expectation that
the same would result in more efficient operation of the Building or are made by
Landlord pursuant to any governmental law, regulation or action not applicable
to the Building at commencement of construction of the Building; provided that
the cost of each such capital improvement, together with any financing charges
incurred in connection therewith, shall be amortized over the useful life
thereof and only that portion attributable to each Operating Year shall be
included herein for such Operating Year;

          (xii) a management fee for the operation and management of the
Property, which shall be equal to three and one-half percent (3.5%) of gross
revenues; and

          (xiii) costs and expenses incurred in order to comply with covenants
and conditions contained in liens, encumbrances and other matters of public
record affecting the Property.

          Any of the foregoing costs which under generally accepted accounting
principles would be considered capital expenditures shall be amortized in
accordance with generally accepted accounting principles.

          d. "Tax Year" means the assessment and taxation year established by
the applicable taxing authority.

          e. "Taxes" means all real estate taxes, assessments (special or
otherwise), levies, ad valorem charges, benefit charges, rates and charges,
privilege permits and any other governmental liens, impositions or charges of a
similar or dissimilar nature, and any payments in lieu of such charges,
regardless of whether any such items shall be extraordinary or ordinary, general
or special, foreseen or unforeseen, levied, assessed or imposed on or with
respect to all or any part of the Building and the land upon which the Building
is situated ("Land") or upon the rent due and payable hereunder by any
governmental authority; provided, however, that if at any time during the Term
or any extension thereof the method of taxation prevailing at the commencement
of the Term shall be altered or eliminated so as to cause the whole or any part
of the above items which would otherwise be included in Taxes to be replaced by
a levy, assessment or imposition, which is (A) a tax assessment, levy,
imposition or charge based on the rents received from the Building and Land
whether or not wholly or partially a capital levy or otherwise, or (B) a tax,
assessment, levy, imposition or charge measured by or based in whole or in part
upon all or any portion of the Building and Land and imposed on Landlord, or (C)
a license fee measured by the 

                                       9
<PAGE>
 
rent payable by Tenant to Landlord, or (D) any other tax, levy, imposition,
charge or license fee, however described or imposed, then such levy, assessment
or imposition shall be included in Taxes.

     7.2. Payment of Operating Cost Increase.  Commencing with the second Rental
Year in the Term, Tenant shall pay the Operating Cost Increase in equal monthly
installments, in advance, on the first day of each calendar month during the
Term.

     7.3. Payment of Taxes.  For each Tax Year, Tenant shall pay its Fractional
Share of all Taxes, which shall be computed by multiplying the actual Taxes
assessed for the Tax Year in question by Tenant's Fractional Share, and which
shall be paid to Landlord as Additional Rent within thirty (30) days of
invoicing by Landlord; provided, however, for so long as an agreement is in
effect between Landlord and the City of Baltimore providing for a PILOT for real
estate taxes which would otherwise be payable with respect to the Premises,
Tenant shall pay to Landlord, in lieu of real estate taxes, the PILOT set forth
in Section 1.C.(1).  The Base PILOT is included in the Annual Basic Rent for the
first Rental Year.  For each Tax Year commencing after the first Rental Year,
Tenant shall pay, as Additional Rent, the PILOT Increase.  Nothing in this
paragraph shall be deemed to relieve Tenant from the payment of its Fractional
Share of Taxes which are not subsumed in the PILOT.

      8.  USE, CARE AND REPAIR OF PREMISES BY TENANT.

     8.1.      Permitted Uses.  Tenant shall use and occupy the Premises solely
for general office purposes in accordance with all applicable laws, codes, and
regulations and for no other purpose Tenant shall not do anything or permit
anything to be done in or on the Premises, or bring or keep anything therein
which will, in any way, obstruct, injure or interfere with the rights of
Landlord or other tenants, or subject Landlord to any liability for injury to
persons or damage to property, or interfere with, the good order of the
Building.

     8.2.      Care of Premises.  Tenant shall, at its sole expense, keep the
Premises and the improvements and appurtenances therein in good order and
condition consistent with the operation of a first-class office building, and at
the expiration of the Term, or at the sooner termination of this Lease as herein
provided, deliver up the same broom clean and in as good order and condition as
at the beginning of the Term, ordinary wear and tear and damage by fire or other
casualty excepted.  Tenant, at its sole expense, shall promptly replace damaged
or broken doors and glass in the interior of the Premises which are caused by
Tenant and shall be responsible for the repair and maintenance of all Tenant
Improvements (except in the event of a defect, which shall be the responsibility
of Landlord or its contractor) and Alterations, including, without limitation,
the repair and replacement of appliances and equipment installed specifically
for Tenant such as refrigerators, disposal, computer room air conditioning,,
sinks and special plumbing, special light fixtures and bulbs for those fixtures,
nor-standard outlets and plug-in strips, and special cabinetry.  Tenant shall
not operate any equipment within the Premises which will exceed the electric
load of six (6) watts per square foot of Rental Area (exclusive of lighting)
plus one and one half (1.5) warts of 277V power lighting.  Consistent with the
provisions of Section 22, Tenant shall pay for all damage to the Premises and
the Building and any fixtures and appurtenances related thereto, as well as for
all property damage sustained by other tenants or occupants of the Building, 

                                       10
<PAGE>
 
due to any waste, misuse or neglect of the Premises and any fixtures and
appurtenances related thereto or due to any breach of this Lease by Tenant, its
employees, agents, or representatives.

     8.3. Hazardous Substances. Tenant covenants and agrees that, other than the
use and storage of ordinary business office and cleaning supplies (such as
copier toner) in small quantities, it will not use or allow the Premises to be
used for the storage, use, treatment or disposal of any "hazardous substance,"
as defined under either the Comprehensive Environmental Response, Compensation
and Liability Act of 1980(42 U.S.C. (S)9601 et. seq, as amended) and similar
state and local statutes.

     Landlord shall be responsible for the containment and remediation of any
release of a hazardous substance within the Building to the extent such release
exists prior to the Tenant's work on the Tenant Improvements or arises directly
from the actions of Landlord, its agents, servants and employees, and not solely
from Landlord's position as an owner/operator of the Property.

     Tenant shall indemnify and hold harmless Landlord and its agents from and
against any damages, claims, judgments, fines, penalties, costs, liabilities
(including sums paid in settlement of claims) or loss including reasonable
attorneys' fees, reasonable consultants' fees, and reasonable expert fees
(collectively "Damage") incurred as a direct result of Tenant's use, handling,
generation, treatment, storage, disposal, other management or release of any
hazardous substance at or from the Premises, whether or not Tenant has acted
negligently with respect to such hazardous substance.  This indemnity shall
survive the expiration or earlier termination of this Lease.

     8.4. Compliance with Laws.

     Tenant, at its sole cost and expense, shall conform to and comply with and
shall cause the Premises to conform to and comply with all federal, state,
county, municipal and other governmental statutes, laws, rules, orders,
regulations, and ordinances applicable to Tenant or resulting from Tenant's use
or occupancy of the Premises.  The Tenant may, after notice to Landlord, by
appropriate proceedings conducted at the Tenant's expense, contest the validity
or enforcement of any such legal requirements or alleged violation thereof so
long as doing so does not result in any lien against the Building or claim
against Landlord.  Landlord shall be responsible at its own cost and expense,
for any repairs, alterations or Base Building Improvements, including the Land
and the Common Areas of the Building, to the extent required to comply with
applicable building codes, the American with Disabilities Act, and any other
applicable federal, state or local laws, rules, orders, regulations or
ordinances.

      9.  RULES AND REGULATIONS.

     Tenant and its agents and invitees shall abide by and observe the rules and
regulations attached hereto as Schedule E for the operation and maintenance of
the Building or any new rules and regulations which may from time to time be
issued by Landlord ("Rules and Regulations"), provided that any new rules or
regulations are not inconsistent with the provisions of this Lease.  Landlord
shall enforce such rules and regulations against 

                                       11
<PAGE>
 
all tenants in the Building in a non-discriminatory manner, but Landlord shall
not be liable to Tenant for any violation of these rules and regulations by any
other tenant or its agents or invitees.

      10. COMMON AREA.

     10.1. Definition of Common Area. As used herein, "Common Area" means those
areas and facilities furnished by Landlord in the Building and as designated by
Landlord from time to time, intended for the general common use and benefit of
all tenants of the Building and their agents, representatives, licensees,
employees and invitees, including, without limitation, any and all stairs,
landings, roof, utility and mechanical rooms and equipment, service closets,
corridors, elevators, lobbies, lavatories and other public areas of the
Building. In no event shall "Common Area" include any areas located within the
Premises as outlined on Schedule A.

     10.2. Use of Common Area. During the Term, Tenant shall have a non-
exclusive easement to use the Common Area in common with Landlord, other tenants
in the Building, and others entitled to the use thereof, subject to such
reasonable rules and regulations governing the use of the Common Area as
Landlord may from time to time prescribe and subject to such easements therein
as Landlord may from time to time grant to others. Tenant shall not obstruct in
any way any portion of the Common Area or in any way interfere with the rights
of other persons entitled to use the Common Area and shall not, without the
prior written consent of Landlord, use the Common Area in any manner, directly
or indirectly, for the location or display of any merchandise or property
belonging to Tenant or for the location of signs relating to Tenant's operations
in the Premises except that signs may be located in those locations provided in
this Lease or approved by Landlord. - The Common Area shall at all times be
subject to the exclusive control and management of Landlord.

     10.3. Alterations to the Common Area. Landlord reserves the right at any
time and from time to time, upon thirty (30) days' prior notice to Tenant, (i)
to change or alter the location, layout, nature or arrangement of the Common
Area or any portion thereof, including but not limited to the arrangement and/or
location of entrances, passageways, doors, corridors, stairs, lavatories,
elevators, and other public areas of the Building, and (ii) to construct
additional improvements adjacent to the Building, to make alterations thereof
and build additional stories on or in any such buildings or build adjoining
same; provided, however, that no such change or alteration shall (a) materially
interfere with Tenant's access to the Building or the Premises (b) reduce the
Rental Area of the Premises (unless such reduction is required by Federal, State
or local laws or regulations, in which event, the provisions of Section 18 shall
apply), (c) invite access by the general public into the lobby of the Building
used by Tenant, (d) materially diminish the availability of air and light to the
Premises, or (e) change or restrict freight access to the Premises. Tenant
acknowledges that retail operators located in the Building lobby may have an
entrance to the Building lobby for the convenience of the office tenants of the
Building, and Tenant agrees that such entrances shall not constitute a violation
of this Section 10.3. Landlord shall have the right to close temporarily all or
any portion of the Common Area to such extent as may, in the reasonable opinion
of Landlord, be necessary to prevent a dedication thereof to the public,
provided that Tenant retains reasonable access to the Premises, or for repairs,
replacements or maintenance 

                                       12
<PAGE>
 
to the Common Area, provided such repairs, replacements or maintenance are
performed expeditiously and in such a manner as not to materially restrict
Tenant's access to the Premises.

     10.4. Maintenance. Landlord covenants to keep, maintain, manage and operate
the Common Area in a manner consistent with the operation of a first class
office building. Landlord reserves the right of access to the Common Area
through the Premises for the purposes of operation, decoration, cleaning,
maintenance, safety, security, alterations and repairs with prior notice to
Tenant and at such time or times as are reasonably acceptable to Tenant except
in the case of an emergency.

     11. SERVICES AND UTILITIES.

     So long as an Event of Default does not exist under this Lease, Landlord
shall provide the following facilities and services to Tenant:

          a.   At least one (1) passenger elevator subject to call at all times,
including Sundays and holidays, subject to scheduled maintenance and repairs.

          b.   During "normal business hours" as hereinafter defined, central
heating and air conditioning during the seasons of the year when these services
are normally and usually furnished, and within the temperature ranges and in
such amounts normally or usually furnished in first-class office buildings in
downtown Baltimore City.  For the purposes of this paragraph b, the term "normal
business hours" shall mean the periods from 7:00 a.m. until 6:00 p.m. Monday
through Friday, excluding the holidays of New Year's Day, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Landlord shall
provide the aforesaid services at other times provided Tenant gives Landlord
notice by 1:00 p.m. on weekdays for after-hour service on the next weekday, by
1:00 p.m. the day before a holiday for service on a holiday, and by 1:00 p.m. on
Friday for service on Saturday or service on Sunday.  Landlord reserves the
right to adjust, from time to time, the rate at which such services shall be
provided corresponding to adjustments in Landlord's costs. Tenant shall pay for
such service, as Additional Rent, promptly upon receipt of an invoice with
respect thereto.

          c.   Electricity for lighting and power.

          d.   Cleaning in accordance with the specifications set forth in
Schedule F attached hereto and made a part hereof, pursuant to annual contracts
for such services with contractors selected through Landlord's customary bidding
process.

          e.   Rest room facilities and necessary lavatory supplies, including
hot and cold running water at the points of supply, as provided for general use
of all tenants in the Building and routine maintenance, painting, and electric
lighting service for all public areas of the Building in such manner as Landlord
deems reasonable.

          f.   Hot and cold running water to rest room facilities and kitchen
areas located within the Premises.

                                       13
<PAGE>
 
          g.   Security for the Building in accordance with the security plan
provided by Landlord and reasonably approved by Tenant.

     Unless a different standard is prescribed for such services, all services
shall be comparable to those supplied in first-class office buildings in
downtown Baltimore City.  Any failure by Landlord to furnish the foregoing
services, resulting from circumstances beyond Landlord's reasonable control or
from interruption of such services due to non-routine repairs or maintenance,
shall not render Landlord liable in any respect for damages to either person or
property, nor be construed as an eviction of Tenant, nor cause an abatement of
rent hereunder, nor relieve Tenant from any of its obligations hereunder
provided Landlord takes all commercially reasonable actions to rectify such
failure.  If any public utility or governmental body shall require Landlord or
Tenant to restrict the consumption of any utility or reduce any service for the
Premises or the Building, Landlord and Tenant shall comply with such
requirements, whether or not the utilities and services referred to in this
Section 11 are thereby reduced or otherwise affected, without any liability on
the part of Landlord to Tenant or any other person or any reduction or
adjustment in rent payable hereunder; provided, however, Tenant shall have the
right to contest or dispute such restriction or reduction by appropriate
proceedings provided such contest or dispute does not result in a lien against
the Building or a claim against Landlord.  Landlord and its agents shall be
permitted reasonable access to the Premises upon prior reasonable notice to
Tenant for the purpose of installing and servicing systems within the Premises
deemed necessary by Landlord to provide the services and utilities referred to
in this Section 11 to Tenant and other tenants in the Building.

      12. PARKING.

     During the Term, Tenant shall have the right to use (but shall not be
obligated to use) four (4) unassigned parking spaces in the parking area; two
(2) of which shall be in the North Warehouse Lot and two (2) of which shall be
in Lot A at the monthly rate of Seventy Dollars ($70.00) per space for the North
Warehouse Lot and Seventy-five Dollars ($75.00) per space for Lot A for the
first Rental Year ("Parking Fees"), such parking fees to increase each
subsequent Rental Year by three percent (3%) over the previous year's Parking
Fee.

     Tenant, or its employees wishing to use such spaces, shall enter into
separate monthly contracts for such spaces with Landlord's parking operator at
the rates described above. Tenant acknowledges that all parking spaces must be
vacated ninety (90) minutes before a scheduled game on those weekdays during the
major league baseball season (and post-season, if applicable) on which nighttime
games are scheduled and any time during the year when baseball related events
open to the public for use of field and stands are scheduled, and that the
parking operator shall have the right to have any vehicle parked in violation of
such contract removed from the parking lot at Tenant's or its employee's cost.
Tenant further acknowledges that such parking spaces shall not be used within
ninety (90) minutes of the scheduled game or event time on those weekdays during
the baseball season (and post-season, if applicable) on which daytime games are
scheduled and any time during the year when baseball related events open to the
public for use of field and stands are scheduled, unless the game or other event
is canceled.  Landlord shall have the right to relocate the parking spaces from
time to time during the Term.

                                       14
<PAGE>
 
     Tenant shall have the further right in common with others, without charge,
to use of bicycle parking areas.

     13. LOSS, DAMAGE AND INJURY.

     Subject to the terms of this Lease, Tenant shall occupy and use the
Premises, the Building and the Common Area at Tenant's own risk.  Consistent
with the provisions of subsection 16.4, Tenant's Personal Property and the
property of those claiming by, through or under Tenant, located in or on the
Premises or the Building, shall be and remain at the sole risk of Tenant or such
other person except for damage or loss caused by the gross negligence or willful
misconduct of the Landlord and not covered or required to be covered by Tenant's
insurance as provided under Section 16.1 hereof.

     Although Landlord shall use reasonable diligence in application of the
security plan, no representation, guaranty, assurance, or warranty is made or
given by Landlord that the communications or security systems, devices or
procedures used, if any, will be effective to prevent injury to Tenant or any
other person or damage to, or loss (by theft or otherwise) of any of Tenant's
Personal Property or of the property of any other person, and Landlord reserves
the right to modify the Security Plan at any time without liability to Tenant
provided that such modification does not effect a diminishment in the level of
security provided.

     14. REPAIRS BY LANDLORD.

     Landlord shall keep the Premises and the Building and all machinery,
equipment, fixtures and systems of every kind attached to, or used in connection
with the operation of, the Building, including all electrical, heating,
mechanical, sanitary, sprinkler, utility, power, plumbing, cleaning,
refrigeration, ventilating, air conditioning and elevator systems and equipment
(excluding, however, lines, improvements, systems and machinery for water, gas,
steam and electricity owned and maintained by any public utility company or
governmental agency or body) in good order and repair consistent with the
operation of the Building as a first-class office building.  Further, Landlord
shall keep the pedestrian walkways around the Building, the private driveways
and the Parking Areas in good repair and reasonably free of snow and ice.
Landlord, at its expense (subject to reimbursement by Tenant pursuant to Section
7), shall make all repairs and replacements necessary to comply with its
obligations set forth in the immediately preceding sentence, except for (a)
repairs required to be made by Tenant pursuant to Section 8 and (b)
notwithstanding the provisions of Section 16.4, repairs caused by the negligence
or willful misconduct of Tenant, its agents and employees, which repairs shall
be made by Landlord at the cost of Tenant, and for which Tenant shall pay
promptly, as Additional Rent, upon receipt of an invoice setting forth the cost
of such repairs.

     15. ALTERATIONS,  TITLE AND PERSONAL PROPERTY.

     15.1. Alterations.  Tenant shall in no event make or permit to be made
any alteration, modification, substitution or other change of any nature to the
mechanical, electrical, plumbing, HVAC and sprinkler systems within or serving
the Premises without the 

                                       15
<PAGE>
 
prior written approval of Landlord. After completion of Tenant's Improvements
within the Premises, Tenant shall not make or permit any other improvements,
alterations, fixed decorations, substitutions or modifications, structural or
otherwise, to the Premises or the Building ("Alterations") without the prior
written approval of Landlord. Landlord shall not unreasonably withhold or delay
its consent to Alterations which do not affect the structural, mechanical,
plumbing or electrical elements or systems of the Building and which are not
visible from outside the Premises, provided such work conforms with the general
design standards of the Building. Landlord's approval shall include the
conditions under which acceptable Alterations may be made. Alterations shall
include, but not be limited to, the installation or modification of carpeting,
walls, partitions, counters, doors, shelves, lighting fixtures, hardware, locks,
ceiling, window and wall coverings; but shall not include the initial Tenant's
Improvements placed within the Premises pursuant to Section 5.1. All Alterations
shall be based on complete plans and specifications prepared and submitted by
Tenant to Landlord for approval, except in the instance of cosmetic changes,
such as painting and carpeting, in which case Tenant shall provide Landlord with
samples showing colors, styles, etc. Alterations shall not be made until (a)
Landlord has approved Tenant's contractor, (b) Tenant has provided Landlord with
certificates of insurance meeting the requirements of Section 16.1.A.(iv), and
(c) Tenant has furnished Landlord with all necessary permits and licenses. If
required for issuance of a permit, Landlord agrees to execute, at no cost to
Landlord, any permit application for Alterations approved by Landlord. All such
work shall be subject to reasonable rules and regulations prescribed by Landlord
for tenant construction. Alterations made by Landlord at Tenant's request shall
be at Tenant's sole cost, payable by Tenant, as Additional Rent, within thirty
(30) days after receipt of an invoice for same from Landlord, which cost shall
include Landlord's standard construction management fee, which shall be agreed
upon between Landlord and Tenant prior to commencement of the Alterations.
Tenant shall be responsible for the cost of any additional improvements within
the Premises or the Common Area required by The Americans with Disabilities Act
of 1990 as a result of Tenant's Alterations.

     If Tenant makes any Alterations without the prior consent of Landlord,
then, in addition to Landlord's other remedies, Landlord may correct or remove
such Alterations and Tenant shall pay the cost thereof, as Additional Rent, on
demand.

     15.2.     Title.    The Tenant Improvements, all Alterations and all
equipment, fixtures, machinery, furnishings, and other improvements installed in
the Premises by or on behalf of Landlord or Tenant, other than Tenant's Personal
Property, (a) shall immediately become the property of Landlord upon
installation, and (b) shall remain upon and be surrendered to Landlord with the
Premises as a part thereof at the end of the Term.  Notwithstanding the
foregoing, Landlord may, upon notice to Tenant at the time Alterations are
submitted for approval, elect that any Alterations be removed at the end of the
Term, and thereupon, Tenant shall at its sole expense, cause such Alterations to
be removed and restore the Premises to its condition prior to the making of such
Alterations, reasonable wear and tear excepted.  If Tenant does not complete
such removal within a reasonable period, Landlord shall have the right to do so
and Tenant shall promptly reimburse Landlord, as Additional Rent, for the cost
of such work, which reimbursement obligation shall survive termination of the
Lease.

                                       16
<PAGE>
 
     15.3.     Tenant's Personal Property.  "Tenant's Personal Property" means
all equipment, machinery, furniture, furnishings and/or other property now or
hereafter installed or placed in or on the Premises by and at the sole expense
of Tenant with respect to which Tenant has not been granted any credit or
allowance by Landlord and which do not constitute Tenant Improvements or
Alterations or any substitute therefor or replacement thereof. Notwithstanding
any other provision of this Lease, Tenant's Personal Property shall not include
any Alterations or any improvements or other property installed or placed in or
on the Premises as part of Tenant's Improvements, whether or not installed at
Tenant's expense. Tenant shall promptly pay all personal property taxes on
Tenant's Personal Property, as applicable. Provided that there shall not have
been an Event of Default under this Lease, Tenant may remove all Tenant's
Personal Property from the Premises at the termination of this Lease. Any
property belonging to Tenant or any other person which is left in the Premises
after the Termination Date, or within ten (10) days after an earlier termination
of the Lease, shall be deemed to have been abandoned. In such event, Landlord
shall have the right to declare itself the owner of such property and to dispose
of it in whatever manner Landlord considers appropriate without waiving its
right to claim from Tenant all expenses and damages caused by Tenant's failure
to remove such property, and Tenant shall not have any right to compensation or
claim against Landlord as a result.

     15.4.     Tenant's Right to Certain Items.  Notwithstanding any of the
foregoing provisions of this Section 15 to the contrary, Tenant shall always be
entitled, following an Event of Default hereunder, to the possession of its
books and records, computer programs, stationery, standard office forms unique
to Tenant, currency, the property of third parties, to the extent any of the
foregoing is located within the Premises, and confidential customer information;
provided, however, in the event Landlord must remove any of the foregoing items
from the Premises in the course of the exercise by Landlord of its remedies
under this Lease, Landlord shall store the foregoing items in a secure place and
Tenant shall reimburse Landlord as Additional Rent or otherwise any and all
costs incurred by Landlord in connection therewith, including, but not limited
to, any removal and/or storage costs so incurred.  Notwithstanding the
immediately preceding sentence, if Landlord has given Tenant at least ten (10)
days' prior notice of Landlord's intent to remove any of the foregoing items
from the Premises and Tenant fails to remove all of such items from the Premises
within said ten (10) day period, Landlord, its agents, employees and contractors
shall have no liability in regard to the removal and/or storage thereof.

     16. INSURANCE.

     16.1.     Tenant's Insurance.  Tenant, at its expense, shall obtain and
maintain in effect as long as this Lease remains in effect and during such other
time as Tenant occupies the Premises or any part thereof insurance policies in
accordance with the following provisions, unless waived in writing by the
Landlord.  In addition, Tenant shall require any subtenant of the Premises to
obtain and maintain such policies.

     A.   Coverage.

          (i) commercial general liability insurance policy, including
contractual liability, with respect to the Building, to afford protection with
limits, per occurrence, of not 

                                       17
<PAGE>
 
less than Two Million Dollars ($2,000,000.00), combined single limit, with
respect to personal injury, bodily injury, including death, and property damage
and Two Million Dollars ($2,000,000.00) aggregate (occurrence form), such
insurance to provide for no deductible;

          (ii)  Special Form property insurance policy, including theft, written
at replacement cost value and with replacement cost endorsement, covering all of
Tenant's Personal Property in the Premises, and covering loss of income
resulting from casualty, such insurance to provide for no deductible greater
than Twenty-Five Thousand Dollars ($23,000.00).

          (iii)     worker's compensation or similar insurance policy offering
statutory coverage and containing statutory limits, which policy shall also
provide Employer's Liability Coverage of not less than Five Hundred Thousand
Dollars ($300,000. 00) per occurrence.

          (iv)   Notwithstanding anything set forth above in this subsection
16.1 to the contrary, all dollar limits specified herein shall be increased from
time to time, but not more often than every five (5) years, as reasonably
necessary to effect economically equivalent insurance coverage, or coverage
deemed adequate in light of then existing circumstances.

     B.   Policies.

     Such policies shall be maintained with companies licensed to do business in
the State where the Premises are located and in form reasonably acceptable to
Landlord and will be written as primary policy coverage and not contributing
with, or in excess of, any coverage which Landlord shall carry.  Such policies
shall be provided on an occurrence form basis unless otherwise approved by
Landlord and shall include Landlord and its managing agent as additional insured
as to coverage under paragraphs 16.1 .A.(i) and 16.1 .A.(iv).  Such policies
shall also contain a waiver of subrogation provision and a provision stating
that such policy or policies shall not be canceled, non-renewed, reduced in
coverage or materially altered except after thirty (30) day's written notice,
said notice to be given in the manner required by this Lease to Landlord,
Attention: Deputy Director.  All such policies of insurance shall be effective
as of the date Tenant occupies the Premises and shall be maintained in force at
all times during the Term of this Lease and all other times during which Tenant
shall occupy the Premises.  Tenant shall deposit the policy or policies of such
required insurance or certificates thereof with Landlord prior to the Lease
Commencement Date.

     16.2.     Tenant's Failure to Insure.  If Tenant shall fail to obtain
insurance as required under this Section 16, Landlord may, but shall not be
obligated to, obtain such insurance, and in such event, Tenant shall pay, as
Additional Rent, the premium for such insurance upon demand by Landlord.

     16.3.     Compliance with Policies.  Tenant shall not do or allow to be
done, or keep, or allow to be kept, anything in, upon or about the Premises
which will contravene Landlord's policies insuring against loss or damage by
fire, other casualty, or any other cause, including without limitation, public
liability, or which will prevent Landlord from procuring such policies in
companies acceptable to Landlord.  If any act or failure to act by Tenant in and

                                       18
<PAGE>
 
about the Building and the Premises shall cause the rates with respect to
Landlord's insurance policies to be increased beyond those rates that would
normally be applicable for such limits of coverage, Tenant shall pay, as
Additional Rent, the amount of any such increases upon demand by Landlord.

     16.4.     Waiver of Right of Recovery.  Neither party, including Landlord's
managing agent, shall be liable to the other party, including Landlord's
managing agent, or to any insurance company (by way of subrogation or otherwise)
insuring the other party, for any loss or damage to any building, structure or
other tangible property, or loss of income resulting therefrom, or losses under
worker's compensation laws and benefits even though such loss or damage might
have been occasioned by the negligence of such party, its agents or employees,
if, and to the extent, such loss or damage is covered by the insurance
benefitting the party suffering such loss or damage or is required to be covered
by insurance pursuant to subsections 16.1 or 16.3.

     16.5.     Landlord's Insurance.  Landlord shall carry insurance against
damage or destruction to the Building, including Tenant Improvements and
Alterations but excluding Tenant's Personal Property.  Landlord shall obtain
such insurance either through the self-insurance provided through the State
Insurance Trust Fund, through insurance purchased from commercial insurance
carriers, or through a combination of both, as determined by the Director of
Insurance, State Treasurer's Office.

     Landlord shall not be obligated to repair any damage to Tenant's Personal
Property or replace the same unless caused by Landlord's negligence or willful
misconduct and not covered by Tenant's insurance as required in this subsection
16.1. Neither party shall be responsible for any loss or damage falling under
any deductible applicable to the other party's insurance coverage.

     17. DAMAGE AND DESTRUCTION.

     17.1.     Landlord's Obligation to Repair and Reconstruct.  If, as the
result of fire, the elements, accident or other casualty (any of such causes
being referred to herein as a "Casualty"), the Premises shall be rendered wholly
or partially Untenantable, as hereinafter defined, then, subject to the
provisions of subsection 17.2, Landlord shall cause such damage to be repaired,
including Tenant Improvements and Alterations, to the extent proceeds of
insurance (including proceeds of insurance from the State Insurance Trust Fund)
are paid to Landlord, and the Annual Basic Rent and Additional Rent (but not any
Additional Rent due Landlord either by reason of Tenant's failure to perform any
of its obligations hereunder or by reason of Landlord's having provided Tenant
with additional services hereunder) shall be abated proportionately as to the
portion of the Premises rendered untenantable during the period of such
untenantability.  All such repairs shall be made at the expense of Landlord,
subject to the availability of proceeds of insurance and Tenant's
responsibilities set forth herein.  Landlord shall not be liable for
interruption to Tenant's business or for damage to or replacement or repair of
Tenant's Personal Property, all of which replacement or repair shall be
undertaken and completed by Tenant, at Tenant's expense.  For purposes of this
Lease, the Premises shall be deemed "Untenantable" if Tenant is unable to use
the Premises for the purposes originally intended.

                                       19
<PAGE>
 
     If the Premises shall be damaged by Casualty, but the Premises shall not be
thereby rendered wholly or partially untenantable, Landlord shall promptly cause
such damage to be repaired and there shall be no abatement of rent reserved
hereunder.

     17.2.     Termination of Lease.  If the Premises are (a) rendered wholly
untenantable, or (b) damaged as a result of any cause which is not covered by
Landlord's insurance, or if the Building is damaged to the extent of fifty
percent (50%) or more of the Rental Area thereof, or if, for reasons beyond
Landlord's control or by virtue of the terms of any financing of the Building,
sufficient insurance proceeds are not available for the reconstruction or
restoration of the Building or Premises, then, in any of such events, Landlord
may elect to terminate this Lease by giving to Tenant notice of such election
within ninety (90) days after the occurrence of such event, or after the
insufficiency of such proceeds becomes known to Landlord, whichever is
applicable.  If such notice is given, the rights and obligations of the parties
shall cease as of the date set forth in such notice, and the Annual Basic Rent
and Additional Rent (but not any Additional Rent due Landlord either by reason
of Tenant's failure to perform any of its obligations hereunder or by reason of
Landlord's having provided Tenant with additional services hereunder) shall be
adjusted as of the date set forth in such notice, or, if the Premises were
rendered untenantable, as of the date of the Casualty.

     Within ninety (90) days following a Casualty, Landlord shall notify Tenant
in writing of the date on which Landlord, in its best professional judgment,
estimates restoration to be substantially complete.  If restoration is expected
to exceed one hundred eighty (180) days from the date of the Casualty, then
Tenant shall have the right to terminate this Lease on written notice to
Landlord within fifteen (15) days after receipt of Landlord's notice.  If,
despite Landlord's estimate, restoration is not substantially complete within
one hundred eighty (180) days following the Casualty, then Tenant shall have the
right to terminate this Lease upon written notice to Landlord given within
fifteen (15) days after expiration of said 180-day period.

     17.3.  Demolition of the Building.  If the Building shall be so
substantially damaged that it is reasonably necessary, in Landlord's judgment,
to demolish the Building for the purpose of reconstruction, Landlord may
demolish the same, in which event the Annual Basic Rent and Additional Rent (but
not any Additional Rent due Landlord either by reason of Tenant's failure to
perform any of its obligations hereunder or by reason of Landlord's having
provided Tenant with additional services hereunder) shall be abated to the same
extent as if the Premises were rendered wholly untenantable by a Casualty.

     17.4.     Reinstatement of Lease.  If the Building is restored by Landlord
within one-year period without the benefit of insurance proceeds, then so long
as the Tenant named in this Lease was in occupancy of the Premises at the time
of the Casualty, Tenant shall have a right of first refusal to lease space in
the new building on the same terms and conditions as contained in this Lease.
Tenant shall respond to Landlord's notice of restoration within five (5) days
after receipt of such notice.

     17.5.     Insurance Proceeds.  If the Lease is not terminated pursuant to
subsection 17.2, Landlord shall, subject to the terms of any Mortgage or bond
repayment obligation, disburse and apply any insurance proceeds received by
Landlord to the restoration and rebuilding of 

                                       20
<PAGE>
 
the Building in accordance with subsection 17.1 hereof. All insurance proceeds
payable with respect to the Premises and the Building shall belong to and shall
be payable to Landlord.

     8.  CONDEMNATION.

     18.1.     Termination.  If either the entire Premises or the Building shall
be acquired or condemned by any governmental authority under its power of
eminent domain for any public or quasi-public use or purpose, this Lease shall
terminate as of the date of vesting or acquisition of title in the condemning
authority and the rents hereunder shall be abated on that date.  If less than
the whole but more than twenty-five percent (25 %) of the Agreed Rental Area of
the Premises or more than fifty percent (50%) of the total area of the Building
(even if the Premises are unaffected) or such portion of the Common Area as
shall render the Premises or the Building untenantable should be so acquired or
condemned, Landlord and Tenant shall each have the option to terminate this
Lease by notice given to the other within ninety (90) days of such taking.  In
the event that such a notice of termination is given, this Lease shall terminate
as of the date of vesting or acquisition of title in the condemning authority
and the Annual Basic Rent and Additional Rent (but not any Additional Rent due
Landlord either by reason of Tenant's failure to perform any of its obligations
hereunder, or by reason of Landlord's having provided Tenant with additional
services hereunder) shall be adjusted as of such date.

     If (a) neither Landlord nor Tenant shall exercise their respective options
to terminate this Lease, as hereinabove set forth, or (b)some lesser portion of
the Premises or the Building or Common Area, which does not give rise to a right
to terminate pursuant to this subsection 18.1, is taken by the condemning
authority, this Lease shall continue in force and effect, but from and after the
date of the vesting of title in the condemning authority, the Annual Basic Rent
payable hereunder during the unexpired portion of the Term shall be reduced in
proportion to the reduction in the total Rental Area of the Premises, and any
Additional Rent (but not any Additional Rent due Landlord either by reason of
Tenant's failure to perform any of its obligations hereunder, or by reason of
Landlord's having provided Tenant with additional services hereunder) payable
pursuant to the terms hereof shall be adjusted to reflect the diminution of the
Premises and/or the Building, as the case may be.

     18.2.     Rights to Award.  Tenant shall have no claim against Landlord
arising out of the taking or condemnation, or arising out of the cancellation of
this Lease as a result of any such taking or condemnation, or for any portion of
the amount that may be awarded to Landlord as damages as a result of any taking
or condemnation, or for the value of any unexpired portion of the Term, or for
any property lost through condemnation, and Tenant hereby assigns to Landlord
all its rights, title and interest in and to any such award with regard to the
Premises; provided, however that in the event of a total taking, Tenant may
assert any claim it may have against the condemning authority for compensation
for Tenant's Personal Property lost thereby, loss of income, and for any
relocation expenses compensable by statute and receive such awards therefor as
may be allowed in the condemnation proceedings provided that such awards shall
be made in addition to, and stated separately from, the award made to Landlord
for the Building, the underlying land and the Premises. Landlord shall have no
obligation to contest any taking or condemnation.  This Lease shall terminate as
of the date title vests in the condemning authority.  For the purposes of this

                                       21
<PAGE>
 
subsection, a substantial part of the Premises shall be considered to have been
taken if the entire Premises are considered untenantable as defined in
subsection 17.1.

     If less than twenty-five percent (25%) of the Premises is condemned or
acquired in lieu of condemnation by any governmental authority, the Rent shall
be equitably adjusted as of the date title vests in the governmental authority
and the Lease shall otherwise continue in full force and effect.

     19.   BANKRUPTCY.

     19.1. Event of Bankruptcy.  For purposes of this Lease, each of the
following shall be deemed an "Event of Tenant's Bankruptcy":

           (a)  if Tenant becomes insolvent, as defined in the Bankruptcy Code,
                or under the Insolvency Laws;

           (b)  the commencement of any action or proceeding for the dissolution
                or liquidation of Tenant or for the appointment of a receiver or
                trustee of the property of Tenant, whether instituted by or
                against Tenant, if not bonded or discharged within sixty (60)
                days of the date of the commencement of such proceeding or
                action;

           (c)  if Tenant files a voluntary petition under the Bankruptcy Code
                or Insolvency Laws;

           (d)  if there is filed an involuntary petition against Tenant as the
                subject debtor under the Bankruptcy Code or Insolvency laws,
                which is not dismissed within ninety (90) days of filing, or
                results in issuance of an order for relief against the debtor;
                and

           (e)  if Tenant makes or consents to an assignment of its assets, in
                whole or in part, for the benefit of creditors, or to a common
                law composition of creditors.

     As used herein, (i) "Bankruptcy Code" means title 11 of the United States
Code, 11 U.S.C. Section 101 et. seq. as amended or any successor statute and
(ii) Insolvency Laws means the insolvency laws of any state or territory of the
United States.

     19.2. Assumption by Trustee.  If Tenant becomes the subject debtor in a
case pending under the Bankruptcy Code, Landlord's right to terminate this Lease
under Section 20 hereof shall be subject to the applicable rights (if any) of
the Trustee in Bankruptcy to assume or assign this Lease as then provided for in
the Bankruptcy Code.  However, the Trustee in Bankruptcy must give to Landlord
and Landlord must receive proper written notice of the Trustee's assumption or
rejection of this Lease, within sixty (60) days (or such other applicable period
as is provided for in the Bankruptcy Code) after the date of the Trustee's
appointment.  The failure of the Trustee to give notice of the assumption within
the period shall conclusively and irrevocably constitute the Trustee's rejection
of this Lease and 

                                       22
<PAGE>
 
waiver of any rights of the Trustee to assume or assign this Lease. The Trustee
shall not have the right to assume or assign this Lease unless the Trustee (i)
promptly and fully cures all defaults under this Lease, (ii) promptly and fully
compensates Landlord for all monetary damages incurred as a result of such
default, and (iii) provides to Landlord adequate assurance of future
performance. In the event Tenant is unable to: (i) cure its defaults, (ii)
reimburse Landlord for its monetary damages, or (iii) pay the Rent due under
this Lease on time, then Tenant hereby agrees in advance that it has not met its
burden to provide adequate assurance of future performance, and this Lease may
be terminated by Landlord in accordance with Section 20.

     19.3. Tenant's Guarantor's Bankruptcy.  Notwithstanding any of the
other provisions of this Lease, in the event Tenant's obligations under this
Lease are guaranteed by a guarantor, and said guarantor shall voluntarily or
involuntarily come under the jurisdiction of the Bankruptcy Code, and thereafter
said guarantor or its trustee in bankruptcy, under the authority of and pursuant
to applicable provisions thereof, shall determine to assign the guarantee
obligations of said guarantor hereunder, Tenant and its said guarantor agree
that (a) said guarantor or its trustee will provide Landlord sufficient
information enabling it to independently determine whether Landlord will incur
actual and substantial detriment by reason of such assignment, and (b) "adequate
assurance of future performance" in regard to such guarantee obligations of said
guarantor, as that term is generally defined under the Bankruptcy Code, will be
provided to Landlord by said guarantor or its trustee and its assignee as a
condition of said assignment.

      20.  DEFAULT PROVISIONS AND REMEDIES.

     20.1. Events of Default.  Each of the following shall be deemed an
Event of Default by Tenant under this Lease:

           a. failure of Tenant to pay Annual Basic Rent, Additional Rent,
including the Tenant Improvement Financing, or any other sum required to be paid
under the terms of this Lease, including late charges, within five (5) days
after notice to Tenant of failure to pay, specifying the sums due;
 
           b. failure by Tenant to perform or observe any other term, covenant,
agreement or condition of this Lease, on the part of Tenant to be performed
(other than those obligations of Tenant set forth in subsection 16.2 for which
Tenant shall be entitled to receive no prior notice, and other than the
conditions set forth in paragraphs 20.1.a, c, d, e, f and g, which shall be
governed solely by the provisions set forth herein), within twenty (20) days
after notice thereof from the Landlord, unless such performance shall reasonably
require a longer period, in which case Tenant shall not be deemed in default if
Tenant commences the required performance promptly and thereafter pursues and
completes such action diligently and expeditiously;

           c. the filing of a tax or mechanic's lien against any property of
Tenant which is not bonded or discharged within forty-five (45) days of the date
such lien is filed;

           d. abandonment of the Premises by Tenant;

                                       23
<PAGE>
 
           e.   an Event of Tenant's Bankruptcy;

           f.   the sale of Tenant's interest in the Premises under attachment,
execution or similar legal process; and

           g.   the failure of Tenant to vacate the Premises upon the expiration
of the Term, or the earlier termination thereof pursuant to the other provisions
hereof.

     20.2. Remedies.  Upon the occurrence of an Event of Default, Landlord,
without notice to Tenant in any instance (except where expressly provided for
below or by applicable law) may do any one or more of the following:

           (a) Sell at public or private sale all or any part of the goods,
               chattels, fixtures and other Tenant's Personal Property which are
               or may be put into the Premises during the Term, whether exempt
               or not from sale under execution or attachment (it being agreed
               that said property shall at all times be bound within a lien in
               favor of Landlord and shall be chargeable for all Rent and for
               the fulfillment of the other covenants and agreements herein
               contained) and apply the proceeds of such sale, first, to the
               payment of all costs and expenses of conducting the sale or
               caring for or storing said property (including all attorneys'
               fees), second, toward the payment of any indebtedness, including
               (without limitation) indebtedness for Annual Basic Rent, which
               may be or may become due from Tenant to Landlord, and third, to
               pay Tenant, on demand in writing, any surplus remaining after all
               indebtedness of Tenant to Landlord has been fully paid;

           (b) perform, on behalf and at the expense of Tenant, any obligation
               of Tenant under this Lease which Tenant has failed to perform and
               of which Landlord shall have given Tenant notice, the cost of
               which performance by Landlord, together with interest thereon at
               the Default Rate from the date of such expenditure, shall be
               payable by Tenant to Landlord, as Additional Rent, upon demand.
               Notwithstanding the provisions of this clause (b) and regardless
               of whether an Event of Default shall have occurred, Landlord may
               exercise the remedy described in clause (b) without any notice to
               Tenant if Landlord, in its good faith judgment, believes it would
               be materially injured by failure to take rapid action or if the
               unperformed obligation of Tenant constitutes an emergency;

           (c) elect to terminate this Lease and the tenancy created hereby by
               giving notice of such election to Tenant, and reenter the
               Premises, by summary proceedings or otherwise, and remove Tenant
               and all other persons and property from the Premises, and store
               such property in a public warehouse or elsewhere at the cost of
               and for the account of Tenant without resort to legal process and
               without Landlord being deemed 

                                       24
<PAGE>
 
               guilty of trespass or becoming liable for any loss or damage
               occasioned thereby;

           (d) declare any option which Tenant may have to renew the Term or
               expand the Premises to be null and void and of no further force
               and effect; or

           (e) exercise any other legal or equitable right or remedy which it
               may have.

     Any costs and expenses incurred by Landlord (excluding, however, attorneys'
fees) in enforcing any of its rights or remedies under this Lease shall be paid
to Landlord by Tenant, as Additional Rent, upon demand.

     20.3. Damages.  If this Lease is terminated by Landlord pursuant to
Section 20.2.(c), Tenant nevertheless shall remain liable for (a) any Annual
Basic Rent, Additional Rent, including the Tenant Improvement Financing, and
damages which may be due or sustained prior to such termination, and (b) all
reasonable costs, fees and expenses incurred by Landlord in pursuit of its
remedies hereunder or in renting the Premises to others from time to time,
excluding attorneys' fees.  In addition, Landlord may recover from Tenant
additional damages to compensate Landlord for loss of rent resulting from
termination of the Lease, which, at the election of Landlord, shall be either:



           (i) An amount equal to the rent which, but for termination of this
               Lease, would have become due during the remainder of the Term,
               less the amount of rent, if any, which Landlord shall receive
               during such period from others to whom the Premises may be rented
               (other than any Additional Rent received by Landlord as a result
               of any failure of such other person to perform any of its
               obligations to Landlord), in which case such damages shall be
               computed and payable in monthly installments, in advance, on the
               first day of each calendar month following termination of the
               Lease and continuing until the date on which the Term would have
               expired but for such termination; any suit or action brought to
               collect any such damages for any month shall not in any manner
               prejudice the right of Landlord to collect any damages for any
               subsequent month by a similar proceeding; or

          (ii) an amount equal to the present worth (as of the date of such
               termination) of rent which, but for termination of this Lease,
               would have become due during the remainder of the Term, less the
               present worth of any leases of the Premises for the remainder of
               the Term, in which case such damages shall be payable to Landlord
               in one lump sum on demand and shall bear interest at the Default
               Rate until paid. For purposes of this clause (ii), "present
               worth" shall be computed by discounting such amount to present
               worth at a discount rate equal to one percentage point above the
               discount rate then in effect at the Federal Reserve Bank nearest
               to the location of the Building. If 

                                       25
<PAGE>
 
               Landlord later re-leases the Premises during the remainder of the
               Term it shall reimburse Tenant for such amounts as have been
               paid.

     Damages shall be due and payable immediately upon demand by Landlord
following any termination of this Lease pursuant to Section 20.2.

     If this Lease is terminated pursuant to Section 20.2., Landlord may re-
lease the Premises or any part thereof, alone or together with other premises,
for such term(s) (which may be greater or less than the period which otherwise
would have constituted the balance of the Term) and on such terms and conditions
(which may include concessions or free rent and alterations of the Premises) as
Landlord, in its reasonable discretion, may determine. The failure or refusal of
Landlord to re-lease the Premises or any part or parts thereof shall not release
or affect Tenant's liability for damages.

     Nothing contained in this Lease shall limit or prejudice the right of
Landlord to prove and obtain in proceedings for the termination of this Lease by
reason of bankruptcy or insolvency, an amount equal to the maximum allowed by
any statute or rule of law in effect at the time when, and governing the
proceedings in which, the damages are to be proved, whether or not the amount be
greater, equal to, or less than the amount of the loss or damages referred to
above.

     20.4.  No Waiver.  No act or omission by Landlord shall be deemed to be an
acceptance of a surrender of the Premises or a termination of Tenant's
liabilities hereunder, unless Landlord shall execute a written release of
Tenant.  Tenant's liability hereunder shall not be terminated by the execution
by Landlord of any new lease for all or any portion of the Premises or the
acceptance of rent from any assignee or subtenant.

     20.5.     Remedies Not Exclusive.  All rights and remedies of Landlord set
forth in this Lease shall be cumulative, and none shall exclude any other right
or remedy, now or hereafter allowed by or available under any statute,
ordinance, rule of court, or the common law, either at law or in equity, or
both.  For the purposes of any suit brought or based hereon, this Lease shall be
construed to be a divisible contract, to the end that successive actions may be
maintained on this Lease as successive periodic sums shall mature hereunder. The
failure of Landlord to insist, in any one or more instances, upon a strict
performance of any of the covenants, terms and conditions of this Lease or to
exercise any right or option herein contained shall not be construed as a waiver
or a relinquishment for the future, of such covenant, term, condition, right or
option, but the same shall continue and remain in full force and effect unless
the contrary is expressed by Landlord in writing.  The receipt by Landlord of
rents hereunder, with knowledge of the breach of any covenant hereof or the
receipt by Landlord of less than the full rent due hereunder, shall not be
deemed a waiver of such breach or of Landlord's right to receive the full rents
hereunder, and no waiver by Landlord of any provision hereof shall be deemed to
have been made unless expressed in writing and signed by Landlord.

     20.6.     Persistent Failure to Pay Rent.  In addition to any other
remedies available to Landlord pursuant to this Lease or by law, Landlord may,
at any time throughout the Term of this Lease, terminate this Lease upon
Tenant's default on three (3) separate occasions 

                                       26
<PAGE>
 
during any twelve (12) month period under subsection 20.1 a, regardless of
whether or not such prior defaults have been cured. Termination, pursuant to
this subsection 20.6, shall be effective upon Landlord's delivery to Tenant of a
notice of termination.

     20.7. Landlord's Default.  In the event Landlord fails to perform any
material term, covenant, agreement or condition of this Lease on the part of
Landlord to be performed for a period of five (5) days after notice thereof from
Tenant with respect to any monetary default and as to any other default thirty
(30) days after notice thereof from Tenant, (unless such performance shall
reasonably require a longer period, in which case Landlord shall not be deemed
in default if Landlord commences the required performance promptly and
thereafter continuously pursues and completes such action diligently and
expeditiously) (each of the foregoing being termed an "Event of Landlord's
Default"), Tenant shall be entitled to exercise any and all rights and seek any
and all remedies which Tenant may hold or to which it may be entitled at law or
in equity, including, but not limited to, an action in equity for injunctive
relief and/or the specific performance of this Lease by Landlord, and/or an
action at law for damages.  In the event Tenant is successful in any action or
suit brought against Landlord to assert its rights under the provisions of this
subsection 20.7, such sums shall bear interest at the Default Rate from and
after the date of judgment.

     In addition to the remedies specified above, in the event an Event of
Landlord's Default renders the Premises Untenantable, then Tenant may place Rent
as due in escrow with a mutually acceptable federally insured interest-bearing
bank account subject to Landlord's cure of such breach, and immediately upon
Landlord's cure of such Event of Landlord's Default, or upon a determination in
Landlord's favor (i.e., either that an Event of Landlord's Default does not
exist or has not rendered the Premises Untenantable), all sums so escrowed,
together with accrued interest thereon, shall be paid over to Landlord.  In
addition, in the event of a determination in Landlord's favor, the sums escrowed
shall bear interest at the Default Rate from the date such sums were due under
this Lease through the date of payment to Landlord.

      21.  LANDLORD'S LIEN.

     21.1. Subject to Section 15.4, Tenant hereby grants to Landlord a lien
and security interest on all tangible personal property of Tenant now or
hereafter placed in or upon the Premises, and such property shall be and remain
subject to such lien and security interest of Landlord for payment of all Rent
and other sums agreed to be paid by Tenant herein.  It is provided, however, the
Landlord shall not have a lien which would be superior to a lien from a lending
institution, supplier or leasing company, if such lending institution, supplier
or leasing company has a security interest in the equipment, furniture or other
tangible personal property and which security interest has its origin in a
transaction whereby Tenant (a) originally acquired such equipment, furniture or
other tangible personal property, or (b) with the prior approval of Landlord,
refinanced the debt for such equipment, furniture or other tangible personal
property.

     21.2. The provisions of this paragraph relating to such lien and security
interest shall constitute a security agreement under and subject to the Uniform
Commercial Code of the state where the Premises are located so that Landlord
shall have and may enforce 

                                       27
<PAGE>
 
a security interest on all property of Tenant now or hereafter placed in or on
the Premises, in addition to and cumulative of the Landlord's liens and rights
provided by law or by the other terms and provisions of this Lease.

      22.  INDEMNITY.

     To the maximum extent permitted by law, Tenant shall indemnify, hold
harmless and (at Landlord's option) defend Landlord, its agents, members,
officials, servants and employees from and against all claims, actions, losses,
costs and expenses (including attorneys' and other professional fees),
judgments, settlement payments, and, whether or not reduced to final judgment,
all liabilities, damages, or fines paid, incurred or suffered by any third
parties to the extent arising directly or indirectly from (a) any default by
Tenant under the terms of this Lease, (b) the use or occupancy of the Building
by Tenant or any person claiming through or under Tenant, and/or (c) any acts or
omissions of Tenant or any contractor, agent, employee, invitee or licensee of
Tenant in or about the Building.  The foregoing indemnity is in addition to, and
not in substitution for, any indemnity given by Tenant to Landlord under Section
8.3.

      23. LIMITATION ON LANDLORD LIABILITY.

     The term "Landlord" as used in this Lease shall mean only the owner or the
Mortgagee or its trustees, as the case may be, then in possession of the
Building so that in the event of any transfer by Landlord of its interest in the
Building, the Landlord in possession immediately prior to such transfer shall
be, and hereby is, entirely released and discharged from all covenants,
obligations and liabilities of Landlord under this Lease accruing after such
transfer.  In consideration of the benefits accruing hereunder, Tenant, for
itself, its successors and assigns, covenants and agrees that, in the event of
any actual or alleged failure, breach or default hereunder by the Landlord, and
notwithstanding anything to the contrary contained elsewhere in this Lease, the
remedies of Tenant under this Lease shall be solely and exclusively limited to
Landlord's interest in the Building, subject to the limitations set forth in the
following paragraph.

     Tenant understands and agrees that Landlord is an instrumentality of the
State of Maryland and can exercise only those powers expressly granted to it by
the pertinent Acts of Maryland or those that are necessarily implied from the
powers that are expressly granted, and in the event Landlord is temporarily or
permanently prevented, restricted or delayed in the performance of any or all of
the duties and obligations imposed upon it, or assumed by it by the terms and
provisions of this Lease, Landlord and its members, officers, agents and
employees shall not be liable directly or indirectly for any costs, losses,
damages, injuries or liabilities caused to or suffered or incurred by Tenant or
any other person or legal entity in connection with or as the result of or
growing Out of any such prevention, restriction or delay.

      24. LANDLORD OBLIGATIONS.

     Landlord agrees to perform all of its obligations under this Lease in a
manner consistent with the standards applicable to first-class office buildings
in downtown Baltimore 

                                       28
<PAGE>
 
City. Landlord shall be excused for the period of any delay in the performance
of any of its obligations when the delay is due to any cause or causes beyond
Landlord's control which include, without limitation, acts of God, all labor
disputes, governmental regulations or controls, civil unrest, war, extreme
adverse weather condition, fire or other casualty, inability to obtain any
material or services, unless otherwise provided for in this Lease. Except where
specifically set forth in this Lease, there shall be no abatement, set-off or
deduction of Annual Basic Rent or Additional Rent due under this Lease.

      25.  ASSIGNMENT AND SUBLETTING.

     25.1. Prohibited Without Landlord's Consent.  Tenant agrees for itself
and its permitted successors and assigns in interest hereunder that it will not
(a) assign or otherwise transfer, mortgage or otherwise encumber this Lease or
any of its rights hereunder; (b)sublet the Premises or any part thereof or
permit the occupancy or use of the Premises or any part thereof by any person
other than Tenant; and/or (c) permit the assignment or other transfer of this
Lease or any of Tenant's rights hereunder by operation of law, without the prior
written consent of Landlord in each instance first obtained, which consent shall
not be unreasonably withheld, and any consent given shall not constitute a
consent to any subsequent assignment or subletting. Tenant acknowledges that any
assignment or subletting is also subject to the approval of Baltimore Orioles
Limited Partnership with regard to any prospective use of the Premises.  Any
attempted assignment or subletting without Landlord's consent shall be null and
void and shall not confer any rights upon any purported transferee, assignee,
mortgagee, sublessee, or occupant.  No assignment or subletting, regardless of
whether Landlord's consent has been granted or withheld, shall be deemed to
release Tenant from any of its obligations hereunder or to alter, impair or
release the obligations of any person guaranteeing the obligations of Tenant
hereunder.  Tenant hereby indemnities Landlord against liability resulting from
any claim made against Landlord by any assignee or subtenant or by any broker
claiming a commission in connection with the proposed assignment or subletting.
In the event Landlord shall consent to an assignment of this Lease, any option
which Tenant may have to renew the Term shall be null and void.

     Notwithstanding the foregoing, Tenant shall have the right to assign this
Lease or sublet all or any part of the Premises to a corporation which controls,
is controlled by or is under common control with the corporation named as Tenant
in the introduction to this Lease or to any other entity which is controlled by
the share-holders controlling the Tenant as of the date of this Lease
("Affiliate"). Tenant shall notify Landlord in writing prior to any such
assignment or subletting.  No such assignment or subletting shall relieve the
Tenant named in the introduction to this Lease from its obligations under this
Lease.  If within one (1) year following the assignment or subletting to an
Affiliate, such Affiliate becomes unaffiliated with Tenant, then the assignment
or subletting shall be deemed to have occurred in violation of this Section
25.1.

     25.2. Stock Transfer.  If Tenant is a privately-held corporation, then
each of the following events are prohibited if such event results in a change in
control of Tenant or Guarantor: any transfer of Tenant's or Guarantor's issued
and outstanding capital stock; any issuance of additional capital stock (except
for the initial issuance of stock to investors in the Tenant); or the redemption
of any issued and outstanding stock.  If Tenant is a partnership, 

                                       29
<PAGE>
 
any transfer of any interest in the partnership, or any other change in the
composition of the partnership, which results in a change in management of
Tenant or Guarantor from the person or persons managing the partnership as of
the date hereof, is prohibited. The foregoing shall not be deemed to prohibit
the public issuance of Tenant's stock.

     Notwithstanding the foregoing, the sale of any securities of Tenant to
unrelated third parties pursuant to public or private offerings shall not be
deemed a violation of this Section 25.2 nor shall Tenant be prohibited from
redeeming any of its currently issued and outstanding stock, unless such events
result in a material change in the nature of the business conducted by Tenant
(i.e. administrative offices for a health care and ancillary service provider).

     25.3. Rents from Subletting or Assignment.  In the event Landlord shall
consent to an assignment of this Lease or a subletting of the Premises and the
amount of the rents (or other compensation) to be paid to Tenant by the assignee
or subtenant is greater than the rents required to be paid by Tenant to Landlord
pursuant to this Lease or a premium is to be paid to Tenant for an assignment of
this Lease, Tenant, after deducting its costs of assignment or subletting,
including but not limited to brokers' commissions and the cost of carrying
unused space, shall pay to Landlord (unless waived in writing by Landlord) any
such excess or any such premium, as the case may be, upon receipt thereof by
Tenant from such assignee or subtenant.

     25.4. Procedure for Obtaining Landlord's Consent.

     A.   In the event that, at any time or from time to time prior to or during
the Term, Tenant desires to assign this Lease, whether by operation of law or
otherwise, or sublease all or a portion of the Premises, Tenant shall submit to
Landlord for its consideration (a) in writing, the name and address of the
proposed subtenant or assignee, a reasonably detailed statement of the proposed
subtenant's or assignee's business and reasonably detailed financial references
and information concerning the financial condition of the proposed subtenant or
assignee, (b) a disclosure of the rents to be paid by any subtenant in excess of
the rents reserved hereunder or the premium to be paid for the assignment, and
(c) if a subletting, a description of the area of the Premises to be sublet,
Tenant agrees to pay Landlord, as Additional Rent, all costs incurred by
Landlord in connection with any actual or proposed assignment or subletting,
including, without limitation, the costs of making investigations as to the
acceptability of a proposed subtenant or assignee and legal costs incurred in
connection with any requested consent.

     B.    Landlord's consent to an assignment of this Lease shall be effective
upon the execution by Tenant, the assignee, and Landlord of an assignment
document prepared by Landlord in which the assignee shall agree to assume,
observe, perform, and be bound by, all of Tenant's obligations under this Lease
and Tenant shall agree to remain primarily liable for such obligations.

     Any consent by Landlord to a subletting of all or a portion of the Premises
shall be deemed to have been given only upon the delivery by Landlord to Tenant
of a consent document prepared and executed by Landlord expressly consenting to
such subletting.

     26. HOLDING OVER.

     Tenant agrees to vacate the Premises at the end of the Term, and Landlord
shall be entitled to the benefit of all summary proceedings to recover
possession of the Premises at the end of the Term.  If Tenant remains in
possession of the Premises after the expiration of the Term, such action shall
not renew this Lease by operation of law and nothing herein shall be deemed as a
consent by Landlord to Tenant's remaining in the Premises.  If Tenant fails to
vacate the Premises as required, Landlord may consider Tenant as either (a) a
"Tenant-at-Will" (i.e. month-to-month tenant) liable for the payment of rent at
the then market rate as determined by Landlord or (b) as a "Tenant-Holding Over"
liable for an amount equal to the actual damages incurred by Landlord as a
result of Tenant's holding over, including, without limitation, all actual and
consequential damages and attorney's fees, but in no event shall such amount be
less than an amount equal to one and one-fourth times the Annual Basic Rent, and
Additional Rent, reserved hereunder applicable to the period of the holdover, or
twice the Annual Basic Rent, and Additional Rent, if the Landlord has another
tenant who wishes to lease the Rental Area.  In either event, all other
covenants of this Lease shall remain in full force and effect.

     27. SUBORDINATION AND ATTORNMENT.

     This Lease shall be subject and subordinate to the liens of all mortgages,
deeds of trust and other security instruments now or hereafter placed upon the
Building or any portion thereof and all ground and other underlying leases from
which Landlord's interest is derived (said mortgages, deeds of trust, other
security instruments, and ground leases being hereinafter referred to as
"Mortgages" and the mortgagees, beneficiaries, secured parties, and ground
lessors thereunder from time to time being hereinafter called "Mortgagees"), and
to any and all renewals, extensions, modifications, or refinancing thereof,
without any further act of the Tenant.  If requested by Landlord, however,
Tenant shall promptly execute any certificate or other document confirming such
subordination.  Tenant agrees that, if any proceedings are brought for the
foreclosure of any of the Mortgages, Tenant, if requested to do so by the
purchaser at the foreclosure sale, shall attorn to the purchaser, recognize the
purchaser as the landlord under this Lease, and make all payments required
hereunder to such new landlord without any deduction or set-off of any kind
whatsoever.  Tenant waives the provisions of any law or regulation, now or
hereafter in effect, which may give, or purport to give, Tenant any right to
terminate this Lease or to alter the obligations of Tenant hereunder in the
event that any such foreclosure or termination or other proceeding is prosecuted
or completed.

     Notwithstanding anything contained herein to the contrary, any Mortgagee
may at any time subordinate the lien of its Mortgages to the operation and
effect of this Lease without obtaining the Tenant's consent thereto, by giving
the Tenant written notice thereof, in which event this Lease shall be deemed to
be senior to such Mortgages without regard to the respective dates of execution
and/or recordation of such Mortgages and this Lease and thereafter such
Mortgagee shall have the same rights as to this Lease as it would have had were
this Lease executed and delivered before the execution of such Mortgages.

                                       31
<PAGE>
 
     If, in connection with obtaining financing for the Building, a Mortgagee
shall request reasonable modifications in this Lease as a condition to such
financing, Tenant will not unreasonably withhold, delay or defer its consent
thereto, provided that such modifications do not materially adversely increase
the obligations of Tenant hereunder, or materially adversely affect the
leasehold interest hereby created or Tenant's use and enjoyment of the Premises,
or increase the amount of Annual Basic Rent or Additional Rent payable
hereunder.

     28. ESTOPPEL CERTIFICATES.

     Tenant shall, without charge, at any time and from time-to-time, within
fifteen (13) days after receipt of request therefor by Landlord, execute,
acknowledge and deliver to Landlord a written estoppel certificate, in such form
as may be reasonably determined by Landlord, certifying to Landlord, Landlord's
Mortgagee, any purchaser of Landlord's interest in the Building, or any other
person designated by Landlord, as of the date of such estoppel certificate, the
following, without limitation: (a) whether Tenant is in possession of the
Premises; (b)whether this Lease is in full force and effect; (c) whether there
have been any amendments to this Lease, and if so, specifying such amendments;
(d) whether there are then existing any set-offs or defenses against the
enforcement of any rights hereunder, and if so, specifying such matters in
detail; (e) the dates, if any, to which any rent or other charges have been paid
in advance and the amount of any Security Deposit held by Landlord; (f) that
Tenant has no knowledge of any then existing defaults of Landlord under this
Lease, or if there are such defaults, specifying them in detail; (g)that Tenant
has no knowledge of any event having occurred that authorizes the termination of
this Lease by Tenant, or if such event has occurred, specifying it in detail;
and (h) the address to which notices to Tenant under this Lease should be sent.
Any such certificate may be relied upon by the person or entity to whom it is
directed or by any other person or entity who could reasonably be expected to
rely on it in the normal course of business.  The failure of Tenant to execute,
acknowledge and deliver such a certificate in accordance with this Section 28
within fifteen (15) days after a request therefor by Landlord shall constitute
an acknowledgment by Tenant, which may be relied on by any person who would be
entitled to rely upon any such certificate, that such certificate as submitted
by Landlord to Tenant is true and correct.

     29. PEACEFUL AND QUIET POSSESSION.

     If and so long as Tenant pays all rents due hereunder and performs and
observes the other terms and covenants to be performed and kept by it as
provided in this Lease, Tenant shall and may enter on, have, hold and enjoy the
Premises demised under this Lease, with all the rights, privileges and
appurtenances belonging to it, without any eviction, interruption, suit, claim
or demand by the Landlord and free from any claim or demand by any other person
or entity claiming by, through or under Landlord, subject, however, to the terms
of this Lease, claims and demands arising through Tenant and to matters of
public record existing as of the date of this Lease.

     30. LANDLORD'S ACCESS TO PREMISES.

                                       32
<PAGE>
 
     Landlord and its agents may at any reasonable time and without incurring
any liability to Tenant, other than liability for personal injuries and damages
resulting solely from the negligence or intentional misconduct of Landlord or
its agents, enter the Premises to inspect them or to make alterations or repairs
or for any purpose which Landlord considers necessary for the repair, operation,
or maintenance of the Building; provided, however, that in the case of an
emergency, Landlord may enter the Premises at any time.  Tenant shall allow the
Premises to be exhibited by Landlord (a) at any time during normal business
hours with forty-eight (48) hours' prior notice to Tenant, to any representative
of a lender or to any prospective purchaser of the Building or Landlord's
interest therein or (b) within six (6) months of the end of the Term to any
persons who may be interested in leasing the Premises.

     31.  BROKERS, COMMISSIONS, ETC.

     Landlord and Tenant acknowledge, represent and warrant each to the other
that, no broker, real estate agent or consultant brought about or was involved
in the making of this Lease and that no brokerage fee or commission is due from
Landlord to Tenant or to any other party as a result of the execution of this
Lease.  Tenant agrees to indemnify and hold harmless Landlord against any claim
by any broker, agent, finder or consultant based upon the execution of this
Lease and predicated upon a breach of the above representation and warranty.

     32. RECORDATION.

     Neither Landlord nor Tenant shall record this Lease, any amendment to this
Lease or any other memorandum of this Lease without the prior written consent of
the other party, which consent may be withheld in the sole discretion of either
party and, in the event such consent is given, the party requesting such consent
and recording shall pay all transfer taxes, recording fees and other charges in
connection with such recording.  Notwithstanding the above, Tenant covenants
that if at any time any mortgagee or ground lessor relating to the financing of
the Building shall require the recordation of this Lease, or if the recordation
of this Lease shall be required by any valid governmental order, or if any
governmental authority having jurisdiction in the matter shall assess and be
entitled to collect transfer taxes, documentary stamp taxes, or both, on this
Lease, Tenant, upon the request of Landlord, shall execute such instruments,
including a Memorandum of this Lease, as may be necessary to record this Lease,
and the parties shall share equally all recording fees, transfer taxes and
documentary stamp taxes, payable on, or in connection with, this Lease or such
recordation; provided, however, if Landlord's mortgagee or bond holder requires
such recordation, Landlord shall pay all such fees, taxes and costs.

     33. MANDATORY STATE CLAUSES.

     A.   No employee of the State of Maryland, or any unit thereof, whose
duties as such employee include matters relating to or affecting the subject
matter of this Agreement, shall, while so employed, become or be an employee of
the party or parties hereby contracting with the State of Maryland, or any unit
thereof.  [COMAR Sec. 21.07.01.05]

                                       33
<PAGE>
 
     B.   Tenant shall comply with the provisions of Article 33, Sections 30-1
through 30-4 of the Annotated Code of Maryland, which require that every person
that enters into contracts, leases, or other agreements with the State of
Maryland, including its agencies, or a political subdivision of the State,
during a calendar year under which the person receives in the aggregate $10,000
or more, shall, on or before February 1 of the following year, file with the
Secretary of State of Maryland certain specified information to include
disclosure of political contributions in excess of $ 100 to a candidate for
elective office in any primary or general election.  [COMAR Sec. 21.07.01.20]

     C.   Tenant agrees: (a) not to discriminate in any manner against an
employee or applicant for employment because of race, color, religion, creed,
age, sex, marital status, national origin, ancestry or physical or mental
handicap unrelated in nature and extent so as reasonably to preclude the
performance of such employment; (b) to include a provision similar to that
contained in subsection (a) above in any subcontract except a subcontract for
standard commercial supplies or raw materials, and (c) to post and to cause
subcontractors to post in conspicuous places available to employees and
applicants for employment, notices setting forth the substance of this clause.
[COMAR Sec. 21.07.01.O8]

     D.   If the General Assembly fails to appropriate sufficient funds or if
sufficient funds from an alternative source are not otherwise made available for
continued performance by Landlord for any fiscal period of this Lease succeeding
the first fiscal period, this Lease shall be canceled automatically as of the
beginning of the fiscal year for which funds were not appropriated or otherwise
made available.  The effect of termination of this Lease hereunder will be to
discharge both Landlord and Tenant from future performance of this Lease, except
any obligations which by the terms of this I-ease survive such termination,
including, without limitation, indemnification relating to matters arising under
this Lease prior to the effective date of termination or Tenant's surrender of
the Premises, whichever occurs later. [COMAR Sec. 21.07.01.10]

     E.   Tenant hereby represents and warrants that:

          1.   It is qualified to do business in the State of Maryland and that
it will take such action as, from time to time hereafter, may be necessary to
remain so qualified;

          2.   It is not in arrears with respect to the payment of any monies
due and owing the State of Maryland, or any department or unit hereof,
including, but not limited to, the payment of taxes and employee benefits, and
that it shall not become so in arrears during the Term;

          3.   It shall comply with all federal, state and local laws,
regulations and ordinances applicable to its activities and obligations under
this Lease; and

          4.   It shall obtain at its expense all licenses, permits, insurance,
and governmental approvals, if any, necessary to the performance of its
obligations under this Lease. [COMAR 21.07.01.22]

<PAGE>
 
     F.    Tenant shall, simultaneously with the execution of this Lease,

hereof. [COMAR Sec. 21.07.01.25]

     34.   MISCELLANEOUS.

     34.1. Separability.  If any term or provision of this Lease or the
application thereof to any person or circumstance shall, to any extent, be
invalid or unenforceable, the remainder of this Lease or the application of such
term or provision to persons or circumstances other than those as to which it is
held invalid or unenforceable, shall not be affected thereby, and each term and
provision of this Lease shall be valid and enforceable to the fullest extent
permitted by law.

     34.2. Applicable Law.  This Lease shall be given effect and construed
by application of the laws of the state where the Building is located, and any
action or proceeding arising hereunder shall be brought in the courts in
Baltimore City.

     34.3. Authority.  If Tenant is a corporation or partnership, the person
executing this Lease on behalf of Tenant represents and warrants that Tenant is
duly organized and validly existing; that this Lease has been authorized by all
necessary parties, is validly executed by an authorized officer or agent of
Tenant and is binding upon and enforceable against Tenant in accordance with its
terms.  The person executing this Lease on behalf of Landlord represents that
Landlord has the necessary authority to enter into this Lease.

     34.4. Integration of Agreements.  This writing is intended by the parties
as a final expression of their agreement and is a complete and exclusive
statement of its terms, and all negotiations, considerations and representations
between the parties hereto are incorporated herein. No course of prior dealings
between the parties or their agents shall be relevant or admissible to
supplement, explain, or vary any of the terms of this Lease. Acceptance of, or
acquiescence to, a course of performance rendered under this Lease or any prior
agreement between the parties or their agents shall not be relevant or
admissible to determine the meaning of any of the terms or covenants of this
Lease.  Other than as specifically set forth in this Lease, no representations,
understandings or agreements have been made or relied upon in the making of this
Lease. This Lease can only be modified by a writing signed by each of the
parties hereto.

     34.5. Third Party Beneficiary.  Except as expressly provided elsewhere
in this Lease, nothing contained in this Lease shall be construed so as to
confer upon any other party the rights of a third party beneficiary.

     34.6. Captions; Gender.  The captions used in this Lease are for
convenience only and do not in any way limit or amplify the terms and provisions
hereof.  As used in this Lease and where the context so requires, the singular
shall be deemed to include the plural and the masculine shall be deemed to
include the feminine and neuter, and vice versa.

     34.7. Successors and Assigns.  Subject to the express provisions of
this Lease to the contrary (e.g., Section 25), the terms, provisions and
covenants contained in this Lease shall 

                                       35
<PAGE>
 
apply to, inure to the benefit of, and be binding upon the parties hereto and
their respective heirs, personal representatives, successors and assigns.

     34.8.  No Partnership.  No term, covenant or agreement contained in this
Lease shall act to or be deemed or constructed to create a partnership or joint
venture of or between Landlord and Tenant or to create any other relationship
between the parties other than that of lessor and lessee.

     34.9.  Notices.  All notices, demands and requests required under this
Lease shall be in writing.  All such notices, demands and requests shall he
deemed to have been properly given if sent by United States certified mall,
return receipt requested postage prepaid, or hand delivered, or overnight
delivery with receipt requested, addressed to Landlord or Tenant, at the
Landlord Notice Address and Tenant Notice Address, respectively.  Either party
may designate a change of address by written notice to the other party, in the
manner set forth above.  Notice, demand and requests which shall be served by
certified mail in the manner aforesaid, shall be deemed to have been given three
(3) days after mailing or upon earlier refusal of delivery by the addressee.
Notices sent by overnight delivery shall be deemed to have been given the day
actually delivered or upon earlier refusal of delivery by the addressee.
Without intending to limit the generality of the foregoing requirement that all
notices, demands and requests be in writing, there are certain provisions in
this Lease where, for emphasis alone, such requirement is reiterated.

     34.10. Effective Date of this Lease.  Unless otherwise expressly
provided, all terms, conditions and covenants by Tenant contained in this Lease
shall be effective as of the date first above written.

     34.11. Mechanics' Liens.  Except as to Tenant Improvements, Alterations
or other work at or for the Premises by Landlord, its contractors or agents, in
the event that any mechanics' or materialmen's liens shall at any time be filed
against the Premises purporting to be for work, labor, services or materials
performed or furnished to Tenant or anyone holding the Premises through or under
Tenant, Tenant shall cause the same to be discharged of record or bonded within
forty-five (45) days after the filing thereof.  If Tenant shall fail to cause
such lien to be discharged within forty-five (45) days after the filing thereof,
then, in addition to any other right or remedy of Landlord, Landlord may, but
shall not be obligated to, discharge the same by paying the amount claimed to be
due; and the amount so paid by Landlord, and all costs and expenses, including
reasonable attorneys' fees incurred by Landlord in procuring the discharge of
such lien, shall be due and payable by Tenant to Landlord, as Additional Rent,
on the first day of the next succeeding month.  Notice is hereby given that
Landlord shall not be liable for any labor or materials furnished to Tenant upon
credit and that no mechanics', materialmen's or other liens for any such labor
or materials shall attach to or affect the estate or interest of Landlord in and
to the land and improvements of which the Premises are a part.  Landlord shall
have the same obligations as Tenant and Tenant the same rights as Landlord under
this Section 34.11 with regard to the Common Area and other portions of the
Building, excluding the Premises.

     34.12. Waiver of Right of Redemption.  Tenant hereby expressly waives (to
the extent legally permissible) for itself and all persons claiming by, through
or under it, any right of 

                                       36
<PAGE>
 
redemption or right to restore the operation of this Lease under any present or
future law in the event Tenant is dispossessed for any proper cause, or in the
event Landlord shall obtain possession of the Premises pursuant to the terms of
this Lease. Tenant understands that the Premises are leased exclusively for
business, commercial and mercantile purposes and therefore shall not be
redeemable under any provision of law.

     34.13. Mortgagee's Performance.  If requested by any Mortgagee, Tenant
shall give such Mortgagee written notice of any default by Landlord under this
Lease and a reasonable opportunity to cure such default, provided that such
Mortgagee has entered into a non-disturbance agreement with Tenant.  Tenant
shall accept performance of any of Landlord's obligations hereunder by any
ground lessor or mortgagee relating to the financing of the Building.

     34.14. Mortgagee's Liability.  No mortgagee or ground lessor relating to
the financing of the Building, not in possession of the Premises or the
Building, shall have any liability whatsoever hereunder.

     34.15. Schedules. Each writing or plat referred to herein as being
attached hereto as a schedule or exhibit is hereby made a part hereof, with the
same full force and effect as if such writing or plat were set forth in the body
of this Lease.

     34.16. Time of Essence.  Time shall be of the essence of this Lease with
respect to the performance by Tenant of its obligations hereunder.

     34.17. Amendment.  This Lease may be amended by and only by an instrument
executed and delivered by each party hereto.  No amendments of this Lease
entered into by Landlord and Tenant, as aforesaid, shall impair or otherwise
affect the obligations of any guarantor of Tenant's obligations hereunder, all
of which obligations shall remain in full force and effect and pertain equally
to any such amendments, with the same full force and effect as if the substance
of such amendments was set forth in the body of this Lease.

     34.18. [Intentionally Left Blank]

     34.19. Landlord's Lease with Baltimore Orioles Limited Partnership.
Tenant acknowledges that Landlord has entered into agreements (with amendments,
the "Orioles Agreements") with the Baltimore Orioles Limited Partnership,
regarding, among other matters, uses of space, rights to parking, advertising,
promotions, intellectual property, concessions, maintenance and repair of not
only Oriole Park at Camden Yards (the "Ballpark"), the grounds and walkways
surrounding the Ballpark, the Camden Yards Warehouse Building and portions of
the pedestrian walkway known as Eutaw Street, but also other portions of the
area bounded by Camden Street on the north, Howard Street and Interstate 395 on
the east, Russell Street on the west and Ostend Street on the south ("Camden
Yards"), including parking areas, the exterior and certain interior spaces of
the Camden Yards Warehouse Building, Camden Station and pedestrian and vehicular
access to Camden Yards.  Tenant recognizes that Landlord's obligations under the
Orioles Agreements will affect, among other matters, the ability of Landlord to
approve any changes in use, implement or change the Rules and Regulations and
grant consents required to assign or 

                                       37
<PAGE>
 
sublet the Premises or to place signs, decorations or other material on the
exterior of the Building or portions of the Premises visible from the exterior.
Tenant acknowledges the existence of the Orioles Agreements and accepts the
Premises subject to Landlord's obligations thereunder.

     IN WITNESS WHEREOF, the parties hereto have executed this Lease under their
respective seals as of the day and year first above written.

any rule or regulation under the Securities Act.

              (ii)   The Stockholder has received a copy of the Confidential
Private Placement Memorandum, dated as of December 10, 1996, and the supplement

are subsequently registered under the Securities Act or an exemption from
registration is then available; (C) in any event, the exemption from

the public, and other terms and conditions of Rule 144 are complied with; and
(D) there is now no registration statement on file with the Securities and
Exchange Commission with respect to any stock of PQC and PQC has no obligation
or current intention to register the Common Stock under the Securities Act.

              (vi)   A legend substantially in the following form will be placed
on the certificate representing the Common Stock:

                                INDEMNIFICATION

     7.1  Indemnification.
          --------------- 

          (a) The Stockholders, severally and not jointly, shall indemnify,
defend, and hold harmless PQC, Flagship and their respective subsidiaries and
affiliates and their directors, officers, employees and agents or the successor
of any of the foregoing (collectively, the "PQC Indemnified Parties"), and
reimburse the PQC Indemnified Parties for, from and against all payments,
demands, claims, suits, judgments, liabilities, losses, costs, damages and
expenses, including, without limitation, interest, penalties and reasonable
attorneys' fees, disbursements and expenses (collectively, "Damages"), imposed
on or incurred by any PQC Indemnified Party which relate to or arise out of:

              (i)    breach of any representation and warranty of, or covenant
or agreement to be performed by, the Company or any Stockholder, in each case
contained in this Agreement or the Stockholders Agreement;

              (ii)   failure of any Stockholder to have good, valid and
marketable title to the issued and outstanding Shares held by such Stockholder,
free and clear of all liens, claims, pledges, options, adverse claims or charges
of any nature whatsoever;

              (iii)  any claim by a Stockholder or former stockholder of the
Company, or any other person, firm, corporation or entity, seeking to assert, or
based upon: (A) ownership or rights to ownership of any shares of stock of the
Company; (B) any rights of a stockholder, including any options, preemptive
rights or rights to notice or to vote; (C) any rights under the Articles of
Incorporation or bylaws of the Company; or (D) any claim that such stockholder's
shares were wrongfully repurchased by the Company;

              (iv)   any Tax liabilities of the Company or the Stockholders,
provided however, that with respect to any Stockholder, there is excluded from
Section 7.1 (a)(iv) any amounts actually deducted as a Deductible Expense of
such Stockholder under Section 10.4 of Appendix A of the Services Agreement;

              (v)    the conduct of the Practice prior to the Closing Date,
except for liabilities described in Section 2.8(a) or reflected in the
Settlement Date Financial Certificate required by Schedule 1.14;
                                                  ------------- 

              (vi)   any liability of the Company incurred prior to the Closing
Date that is not described in Schedule 2.8(a);
                              ---------------- 

              (vii)  any liability incurred by PQC or Flagship relating to
agreements or obligations of the Company or any Stockholder, whether written or
oral, that are not specifically identified on the Disclosure Schedule; and

              (viii) to the extent, if any, that on the Closing Date the accrued
but unpaid liabilities of the Company exceeds the sum of (i) the amount actually
collected from

                                      -25-
<PAGE>
 
accounts receivable that arose out of services prior to the Closing Date and
which were uncollected on the Closing Date, (ii) cash and cash equivalents held
by the Company on the Closing Date and (iii) prepaid expenses reflected on the
records of the Company on the Closing Date.

Notwithstanding the foregoing or any other term or condition contained herein or
in any other agreement or instrument referred to herein, the indemnification
obligations of each Stockholder under this Section 7.1(a)(i) - (viii) shall be
limited, in the aggregate, to the dollar value on the Closing Date of the Merger
Consideration paid to such Stockholder reduced by any amount deducted as a
Deductible Expense of such Stockholder under Section 10.4 of Appendix A of the
Services Agreement resulting from any Tax Liabilities of the Company, if, but
only if, the Company has filed all tax returns based on the good faith
determination of its accountants and paid all taxes shown to be due thereon
through the taxable year ending on the date of the Merger.

          (b) PQC and Flagship shall indemnify and hold harmless the Company and
the Stockholders and their respective agents or the successors of any of the
foregoing (collectively, the "Company Indemnified Parties") and together with
the PQC Indemnified Parties (the "Indemnified Parties"), and reimburse such
Company Indemnified Parties for, from, and against all Damages imposed on or
incurred by such Company Indemnified Parties which relate to or arise out of any
breach of any representation or warranty of, or covenant or agreement to be
performed by, PQC or Flagship, in each case contained in this Agreement.

     7.2  Method of Asserting Claims.
          -------------------------- 

          (a) An Indemnified Party shall give prompt written notice to an
indemnifying party (the "Indemnifying Party") of any payments, demands, claims,
suits, judgments, liabilities, losses, costs, damages or expenses (a "Claim") in
respect of which such Indemnifying Party has a duty to provide indemnity to such
Indemnified Party under this Article VII, except that any delay or failure so to
notify the Indemnifying Party only shall relieve the Indemnifying Party of its
obligations hereunder to the extent, if at all, that it is prejudiced by reason
of such delay or failure.

          (b) If a Claim is brought or asserted by a third party (a "Third-Party
Claim"), the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all expenses. The Indemnified Party shall have the right to employ
separate counsel in such Third-Party Claim and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the Indemnified Party.  In the event that the Indemnifying Party, within twenty
(20) days after written notice of any Third-Party Claim, fails to assume the
defense thereof, or in the event the Indemnifying Party fails to demonstrate, to
the reasonable satisfaction of the Indemnified Party, that it has sufficient
assets to meet its indemnification obligations hereunder, the Indemnified Party
shall have the right to undertake the defense, compromise or settlement of such
Third-Party Claim for the account of the Indemnifying Party.  Anything in this
Section 7.2(b) to the contrary notwithstanding, the Indemnifying Party shall
not, without the Indemnified Party's prior written consent, settle or compromise
any Third-Party Claim or consent to the entry of any judgment with respect to
any Third-

                                      -26-
<PAGE>
 
Party Claim which would have any adverse effect on the Indemnified Party, except
as provided immediately below. The Indemnifying Party may, without the
Indemnified Party's prior written consent, settle or compromise any such Third-
Party Claim or consent to entry of any judgment with respect to any Third-Party
Claim which requires solely money damages paid by the Indemnifying Party and
which includes as an unconditional term thereof the release by the claimant or
the plaintiff of the Indemnified Party from all liability in respect of such
Third-Party Claim.

          (c) With respect to any Claim other than a Third Party Claim, the
Indemnifying Party shall have thirty (30) days from receipt of written notice
from the Indemnified Party of such Claim within which to respond thereto.  If
the Indemnifying Party does not respond within such thirty (30) day period, the
Indemnifying Party shall be deemed to have accepted responsibility to make
payment and shall have no further right to contest the validity of such Claim.
If the Indemnifying Party notifies the Indemnified Party within such thirty (30)
day period that it rejects such Claim in whole or in part, the Indemnified Party
shall be free to pursue such remedies as may be available to the Indemnified
Party under applicable law.

     7.3  Survival.  All representations, warranties, covenants and agreements 
          --------                                                 
made by the Parties herein or in any instrument or document furnished in
connection herewith shall survive the Closing and any investigation at any time
made by or on behalf of the Parties hereto. All such representations and
warranties and the Stockholders' obligations pursuant to Sections 7.1(a)(i) and
(viii) and the obligations of PQC and Flagship pursuant to Section 7.1(b) shall
expire on the third anniversary of the Closing Date, except for Claims, if any,
asserted in writing prior to such third anniversary, which shall survive until
satisfied in full or otherwise finally resolved. The obligation of the
Stockholders pursuant to Section 7-1(a)(ii), (iii), (iv), (v), (vi) and (vii)
shall survive until six (6) months after the expiration of the applicable
statute of limitations with respect thereto. All Claims and actions for
indemnity pursuant to this Article VII shall be asserted or maintained in
writing by a Party hereto on or prior to the expiration of such periods.

     7.4  Set-off and Recoupment.  Any amount or amounts due from any
          ----------------------                                     
Indemnifying Party to PQC under this Article VII may be paid to PQC, at PQC's
option, by set-off or recoupment against any amounts due to the Indemnifying
Party pursuant to this Agreement or pursuant to any agreement between the
Indemnifying Party and PQC, Flagship or any of their respective affiliates.  Any
such set-off will be without prejudice to PQC's right to pursue any other
remedies at law or in equity available to it.

                                  TERMINATION

     8.1  Optional Termination.  This Agreement may be terminated and the
          --------------------                                           
transaction contemplated herein abandoned at any time prior to the Closing as

warranty, covenant or agreement on the part of PQC or Flagship set forth in this
Agreement, or if any representation or warranty of PQC or Flagship has become
materially untrue, in either case such that any of the conditions set forth in
Article VI would be incapable of being satisfied by December 20, 1996; provided,
that in any case, a willful breach will be deemed to cause such conditions to be
incapable of being satisfied for purposes of this paragraph (b).   Any breach on
the part of PQC or Flagship of the representations and warranties contained in
Article III or the covenants contained in Article IV, which permits termination
of this Agreement shall permit the Company and the Stockholders to immediately
terminate any other agreement between PQC or Flagship and the Company or any of
the Stockholders;

          (c) by PQC and Flagship upon a material breach of any representation,
warranty, covenant or agreement on the part of the Company or the Stockholders
set forth in this Agreement, or if any representation or warranty of the Company
has become materially untrue, in either case such that any of the conditions set
forth in Article V would be incapable of being satisfied by December 20, 1996;
provided, that in any case, a willful breach will be deemed to cause such
conditions to be incapable of being satisfied for purposes of this paragraph
(c).  Any breach on the part of the Company or the Stockholders of the
representations and warranties contained in Article II or the covenants
contained in Article IV, which permits termination of this Agreement shall
permit PQC and Flagship to immediately terminate any other agreement between the
Company or the Stockholder and PQC or Flagship; or

          (d) by either Party if the Closing shall not have occurred by December
20, 1996, or such other date agreed to by the Parties.

     8.2  Effect of Termination.  In the event this Agreement is terminated

shall, upon another Party's request, deliver to such other Party all documents
previously delivered (and copies thereof in its possession) concerning one
another and the transactions contemplated hereby as required by Section 4.10
above, and (b) none of the Parties nor any of their respective stockholders,
directors, officers or agents shall have any liability to the other Parties,
except for any deliberate breach or deliberate omission resulting in a material
breach of any of the provisions of this Agreement.  In such case, the breaching
Party shall be liable only for the expenses and costs of the non-breaching
Party, and in no event shall either Party be liable for anticipated profits or
consequential damages.  After termination each Party shall keep confidential all
information provided by the others pursuant to this Agreement which is not in
the public domain, shall exercise the same degree of care in handling such
information as it would exercise with similar information of its own, and shall
return any such information upon another Party's request.

                                  ARTICLE IX

                                 ARTICLE VIII

                         SURVIVAL AND INDEMNIFICATION

     8.01  Indemnification.
           --------------- 

     (a) Seller shall indemnify, defend, and hold harmless each of Flagship
and PQC and their respective subsidiaries and affiliates and their respective
directors, officers, employees and agents or the successor of any of the
forgoing (collectively, the "PQC Indemnified Persons"), and reimburse the PQC
Indemnified Persons for, from and against all payments, demands, claims, suits,
judgments, liabilities, losses, costs, damages and expenses, including, without
limitation, interest, penalties and reasonable attorneys' fees, disbursements
and expenses, ("Losses") imposed on or incurred by the PQC Indemnified Persons,
directly or indirectly, which relate to or arise out of any of:  (i) breach of
any representation and warranty of, or covenant or agreements to be performed
by, Seller contained in this Agreement, the Affiliation Agreement or the
Stockholders' Agreement and; (ii) any of the liabilities or obligations retained
by Seller pursuant to Section 1.02.  Notwithstanding the foregoing or any other
term or condition contained herein or in any other agreement or instrument
referred to herein, the indemnification obligations of Seller under this Section
8.01(a) and under the Affiliation Agreement shall be limited, in the aggregate,
to the dollar value on the Closing Date of the Purchase Price and the
consideration under the Affiliation Agreement between Seller and PQC or its
affiliates.

     (b) Flagship and PQC shall indemnify and hold harmless Seller and its
agents (collectively, "Seller Indemnified Persons" and together with the PQC
Indemnified Persons, the "Indemnified Persons"), and reimburse such Indemnified
Persons for, from, and against all Losses imposed on or incurred, directly or
indirectly, by such Indemnified Persons which relate to or arise out of (i)
breach of any representation or warranty of, or covenant or agreement to be
performed by, PQC or Flagship, in each case contained in this Agreement or the
Affiliation Agreement and (ii) the Assumed Liabilities.

     (c) An Indemnified Party shall give prompt written notice to an
indemnifying party (the "Indemnifying Party") of any payments, demands, claims,
suits, judgments, liabilities, losses, costs, damages or expenses (a "Claim") in
respect of which such Indemnifying Party has a duty to provide indemnity to such
Indemnified Party under this Section 8.01, except that any delay or failure so
to notify the Indemnifying Party only shall relieve the Indemnifying Party of
its obligations hereunder to the extent, if at all, that it is prejudiced by
reason of such delay or failure.

     (d) If a Claim is brought or asserted by a third party (a "Third-Party
Claim"), the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all expenses.  The Indemnified Party shall have the right to employ
separate counsel in such Third-Party Claim and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the Indemnified Party.  In the event that the Indemnifying Party, within twenty
(20) days after written notice of any Third-Party Claim, fails to assume the
defense thereof, or in the event the Indemnifying Party fails to demonstrate, to
the reasonable

                                      -22-
<PAGE>
 
satisfaction of the Indemnified Party, that it has sufficient assets to meet its
indemnification obligations hereunder, the Indemnified Party shall have the
right to undertake the defense, compromise or settlement of such Third-Party
Claim for the account of the Indemnifying Party.  Anything in this Section 8.01
to the contrary notwithstanding, the Indemnifying Party shall not, without the
Indemnified Party's prior written consent, settle or compromise any Third-Party
Claim or consent to the entry of any judgment with respect to any Third-Party
Claim which would have any adverse effect on the Indemnified Party, except as
provided immediately below.  The Indemnifying Party may, without the Indemnified
Party's prior written consent, settle or compromise any such Third-Party Claim
or consent to entry of any judgment with respect to any Third-Party Claim which
requires solely money damages paid by the Indemnifying Party and which includes
as an unconditional term thereof the release by the claimant or the plaintiff of
the Indemnified Party from all liability in respect of such Third-Party Claim.

     (e) With respect to any Claim other than a Third-Party Claim, the
Indemnifying Party shall have thirty (30) days from receipt of written notice
from the Indemnified Party of such Claim within which to respond thereto.  If
the Indemnifying Party does not respond within such thirty (30)-day period, the
Indemnifying Party shall be deemed to have accepted responsibility to make
payment and shall have no further right to contest the validity of such Claim.
If the Indemnifying Party notifies the Indemnified Party within such thirty
(30)-day period that it rejects such Claim in whole or in part, the Indemnified
Party shall be free to pursue such remedies as may be available to the
Indemnified Party under applicable law.

     8.02  Survival of Representations; Claims for Indemnification.  All
           -------------------------------------------------------      
representations, warranties, covenants and agreements made by the Parties herein
or in any instrument or document furnished in connection herewith shall survive
the Closing and any investigation at any time made by or on behalf of the
parties hereto.  All such representations and warranties and the Seller's
obligations pursuant to Sections 8.01(a)(i) and (ii) and PQC's and Flagship's
obligations pursuant to Section 8.01(b) shall expire on the third anniversary of
the Closing Date, except for claims, if any, asserted in writing prior to such
third anniversary, which shall survive until finally resolved and satisfied in
full.  All claims and actions for indemnity pursuant to this Section 8 shall be
asserted or maintained in writing by a Party hereto on or prior to the
expiration of such periods.

     8.03  Confidentiality.  The Parties hereto agree to use reasonable
           ---------------                                             
efforts to preserve in full the confidentiality of all confidential business
records and the attorney-client and work-product privileges.  In connection
therewith, each Party hereto agrees that:

     (a) it will use all reasonable efforts, in any action, suit or
proceeding in which it has assumed or participated in the defense, to avoid
production of confidential business records; and

     (b) all communications between any Party hereto and counsel
responsible for, or participating in, the defense of any action, suit or
proceeding shall, to the extent possible, be made so as to preserve any
applicable attorney-client or work-product privilege.

     8.04  Remedies Cumulative.  Except as otherwise provided herein, the
           -------------------                                           
remedies provided herein shall be cumulative and shall not preclude the
assertion by any Party hereto of any other rights or the seeking of any other
remedies against any other Party hereto.

     8.05  Set-off and Recoupment.  Any amount or amounts due from any
           ----------------------                                     
Indemnifying Party to PQC under this Section 8 may be paid to PQC, at PQC's
option, by set-off or recoupment against any amounts due to the Indemnifying
Party pursuant to this Agreement or pursuant to any agreement between the
Indemnifying Party and PQC or any of its affiliates.  Any such set-off will be
without prejudice to PQC's right to pursue any other remedies at law or in
equity available to it.

                                  TERMINATION

transaction contemplated herein abandoned at any time prior to the Closing as
follows:

     (a) by the mutual consent of the Seller, Flagship and PQC;

     (b) by the Seller, upon a material breach of any representation,
warranty, covenant or agreement on the part of PQC or Flagship set forth in this
Agreement, or if any representation or warranty of PQC and Flagship has become
materially untrue, in either case such that any of the conditions set forth in
Article VII would be incapable of being satisfied by December 20, 1996;
provided, that in any case, a willful breach will be deemed to cause such
conditions to be incapable of being satisfied for purposes of this paragraph
(b).  Any breach on the part of PQC or Flagship of the representations and
warranties contained in Article III or the covenants contained in Article IV and
V, which permits termination of this Agreement shall permit the Seller to
immediately terminate any other agreement between PQC and/or Flagship and the
Seller;

     (c) by PQC upon a material breach of any representation, warranty,
covenant or agreement on the part of the Seller set forth in this Agreement, or
if any representation or warranty of the Seller has become materially untrue, in
either case such that any of the conditions set forth in Article VI would be
incapable of being satisfied by December 20, 1996; provided, that in any case, a
willful breach will be deemed to cause such conditions to be incapable of being
satisfied for purposes of this paragraph (c).  Any breach on the part of the
Seller of the representations and warranties contained in Article II or the
covenants contained in Articles IV and V, which permits termination of this
Agreement shall permit PQC and/or Flagship to immediately terminate any other
agreement between Flagship and/or PQC and the Seller; or

     (d) by either party if the Closing shall not have occurred by December
20, 1996; or such other date agreed to by the Parties.

as provided above, (a) each of PQC, Flagship and Seller shall, upon another
Party's request, deliver to such other Party all documents previously delivered
(and copies thereof in its possession) concerning one another and the
transactions contemplated hereby, and (b) none of the Parties nor any of their
respective stockholders, directors, officers or agents shall have any liability
to the other Parties, except for any deliberate breach or deliberate omission
resulting in a material breach of any of the provisions of this Agreement.  In
such case, the breaching Party shall be liable only for the expenses and costs
of the non-breaching Party, and in no event shall either Party be liable for
anticipated profits or consequential damages.  After termination each Party
shall keep confidential all information provided by the others pursuant to this
Agreement which is not in the public domain, shall exercise the same degree of
care in handling such information as it would exercise with similar information
of its own, and shall return any such information upon another Party's request.

obligation, agreement or condition hereunder may only be waived in writing by
PQC if such failure is by Seller and by Seller if such failure is by PQC or
Flagship, but such waiver shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure.  No failure by any Party to take
any action against any breach of this Agreement or default by the other A Party

or to take any such action.

         (c) The Physician represents, warrants and covenants to PQC as follows:

                           Physician's own account for investment only, and not
                           with a view to, or for sale in connection with, any
                           distribution of the PQC Shares in violation of the
                           Securities Act of 1933, as amended (the "Securities
                           Act"), or any rule or regulation under the Securities
                           Act.

                  (ii)     The Physician has received a copy of the Confidential
                           Private Placement Memorandum, dated as of December,
                           1996, with respect to PQC and the PQC Shares and has
                           had such opportunity as the Physician has deemed
                           adequate to obtain from representatives of PQC such
                           information as is necessary to permit the Physician
                           to evaluate the merits and risks of his investment in
                           PQC.

                  (iii)    The Physician has sufficient experience in business,
                           financial and investment matters to be able to
                           evaluate the risks involved in the acquisition of the
                           PQC Shares and to make an informed investment
                           decision with respect to such acquisition.

                  (iv)     The Physician can afford a complete loss of the value
                           of the PQC Shares and is able to bear the economic
                           risk of holding such PQC Shares for an indefinite
                           period.

                  (v)      The Physician understands that (i) the PQC Shares
                           have not been registered under the Securities Act and
                           are "restricted securities" within the meaning of
                           Rule 144 under the Securities Act; (ii) the PQC
                           Shares cannot be sold, transferred or otherwise
                           disposed of unless they are subsequently registered
                           under the Securities Act or an exemption from
                           registration is then available; (iii) in any event,
                           the exemption from registration under Rule 144 will
                           not be available for at least two (2) years and even
                           then will not be available unless a public market
                           then exists for the common stock of PQC, adequate
                           information concerning PQC is then available to the
                           public, and other terms and conditions of Rule 144
                           are complied with; and (iv) there is now no
                           registration statement on file with the Securities
                           and Exchange Commission with respect to any stock of
                           PQC and PQC has no obligation or current intention to
                           register the PQC Shares under the Securities Act.

                  (vi)     A legend substantially in the following form will be 
                           placed on the certificate representing the PQC 
                           Shares:

                           "The shares represented by this certificate were
                           issued in a private placement, without registration
                           under the Securities Act of 1933, as

                           pledged or otherwise transferred in the absence of an
                           effective registration under the Act covering the
                           transfer or an opinion of counsel, satisfactory to
                           the issuer, that registration under the Act is not
                           required."

                  (vii)    The Physician is an "accredited investor" as defined
                           in Rule 501 of the rules and regulations under the
                           Securities Act.

                           the part of PQC or Flagship set forth in this

         5.02     Effect of Termination.
                  ---------------------

         (a) In the event this Agreement is terminated as provided in Section
5.01 above, (i) each of the parties shall deliver to the other parties all
documents previously delivered (and copies thereof in its possession) concerning
one another and the transactions contemplated hereby, and (ii) none of the
parties nor any of their respective stockholders, directors, officers or agents
shall have any liability to the other parties, except for any deliberate breach
or deliberate omission resulting in breach of any of the provisions of this
Agreement. In such case, the breaching party shall be liable only for the
expenses and costs of the non-breaching party, and in no event shall any party
be liable for anticipated profits or consequential damages.

         (b) After termination each party shall keep confidential all
information provided by the others pursuant to this Agreement which is not in
the public domain, shall exercise the same degree of care in handling such
information as it would exercise with similar information of its own, and shall
return any such information upon the other party's request.

                                  ARTICLE VI
                         SURVIVAL AND INDEMNIFICATION

         6.01     Indemnification.
                  ---------------

         (a) Physician shall indemnify, defend, and hold harmless each of
Flagship and PQC and their respective subsidiaries and affiliates and their
respective directors, officers, employees and agents or the successor of any of
the foregoing (collectively, the "PQC Indemnified Persons"), and reimburse the
PQC Indemnified Persons for, from and against all payments, demands, claims,
suits, judgments, liabilities, losses, costs, damages and expenses, including,
without limitation, interest, penalties and reasonable attorneys' fees,
disbursements and expenses ("Damages") imposed on or incurred by PQC Indemnified
Persons, directly or indirectly, which relate to or arise out of any of: (i)
breach of any representation and warranty of, or covenant or agreements to be
performed by, Physician contained in this Agreement, the Asset Purchase
Agreement or the Stockholders Agreement [or the Retiree Stockholders Agreement];
and (ii) any of the liabilities or obligations retained by Physician pursuant to
the Asset Purchase Agreement (which for purposes of this Article V shall be read
as if all qualifications as to the knowledge of the maker of such
representation, warranty or covenant and as to materiality or Material Adverse
Effects or changes were deleted therefrom). Notwithstanding the foregoing or any
other term or condition contained herein or in any other agreement or instrument
referred to herein, the indemnification obligations of Physician under this
Section 6.01(a) and under the Asset Purchase Agreement shall be

                                       -4-
<PAGE>
 
limited, in the aggregate, to the dollar value on the Closing Date of the
aggregate purchase price under the Asset Purchase Agreement and the
consideration under this Agreement.

         (b) Flagship and PQC shall indemnify and hold harmless Physician (the
"Indemnified Physician" and together with the PQC Indemnified Persons, the
"Indemnified Parties"), and reimburse such Indemnified Physician for, from, and
against all Damages imposed on or incurred, directly or indirectly, by such
Indemnified Physician which arise out of or relate to: (i) breach of any
representation or warranty of, or covenant to be performed by, PQC or Flagship,
in each case contained in this Agreement or the Asset Purchase Agreement; and
(ii) the Assumed Liabilities (as defined in the Asset Purchase Agreement).

         (c) An Indemnified Party shall give prompt written notice to an
indemnifying party (the "Indemnifying Party") of any payments, demands, claims,
suits, judgments, liabilities, losses, costs, damages or expenses (a "Claim") in
respect of which such Indemnifying Party has a duty to provide indemnity to such
Indemnified Party under this Section 6.01, except that any delay or failure so
to notify the Indemnifying Party only shall relieve the Indemnifying Party of
its obligations hereunder to the extent, if at all, that it is prejudiced by
reason of such delay or failure.

         (d) If a Claim is brought or asserted by a third party (a "Third-Party
Claim"), the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all expenses. The Indemnified Party shall have the right to employ
separate counsel in such Third-Party Claim and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the Indemnified Party. In the event that the Indemnifying Party, within twenty
(20) days after written notice of any Third-Party Claim, fails to assume the
defense thereof, or in the event the Indemnifying Party fails to demonstrate, to
the reasonable satisfaction of the Indemnified Party, that it has sufficient
assets to meet its indemnification obligations hereunder, the Indemnified Party
shall have the right to undertake the defense, compromise or settlement of such
Third-Party Claim for the account of the Indemnifying Party. Anything in this
Section 6.01(d) to the contrary notwithstanding, the Indemnifying Party shall
not, without the Indemnified Party's prior written consent, settle or compromise
any Third-Party Claim or consent to the entry of any judgment with respect to
any Third-Party Claim which would have any adverse effect on the Indemnified
Party, except as provided immediately below. The Indemnifying Party may, without
the Indemnified Party's prior written consent, settle or compromise any such
Third-Party Claim or consent to entry of any judgment with respect to any
Third-Party Claim which requires solely money damages paid by the Indemnifying
Party and which includes as an unconditional term thereof the release by the
claimant or the plaintiff of the Indemnified Party from all liability in respect
of such Third-Party Claim.

         (e) With respect to any Claim other than a Third-Party Claim, the
Indemnifying Party shall have thirty (30) days from receipt of written notice
from the Indemnified Party of such Claim within which to respond thereto. If the
Indemnifying Party does not respond within such thirty (30) day period, the
Indemnifying Party shall be deemed to have accepted responsibility to make
payment and shall have no further right to contest the validity of such Claim.
If the Indemnifying Party notifies the Indemnified Party within such thirty (30)
day

                                       -5-
<PAGE>
 
period that it rejects such Claim in whole or in part, the Indemnified Party
shall be free to pursue such remedies as may be available to the Indemnified
Party under applicable law.

         6.02     Survival of Representations: Claims for Indemnification. All
                  -------------------------------------------------------
                  representations and warranties made by the parties herein or
                  in any instrument or document furnished in connection herewith
                  shall survive the Closing and any investigation at any time
                  made by or on behalf of the parties hereto. All such
                  representations and warranties and the Physician's obligations
                  pursuant to Sections 6.1(a)(i) and (ii) and PQC's and
                  Flagship's obligations pursuant to Section 6.1(b) shall expire
                  on the third anniversary of the Closing Date, except for
                  claims, if any, asserted in writing prior to such third
                  anniversary, which shall survive until finally resolved and
                  satisfied in full. All claims and actions for indemnity
                  pursuant to this Section 6 shall be asserted or maintained in
                  writing by a party hereto on or prior to the expiration of
                  such periods.

         6.03     Set-off and Recoupment. Any amount or amounts due from any
                  ----------------------
                  Indemnifying Party to PQC under this Section 6 may be paid to
                  PQC, at PQC's option, by set-off or recoupment against any
                  amounts due to the Indemnifying Party pursuant to this
                  Agreement or pursuant to any agreement between the
                  Indemnifying Party and PQC, Flagship or any of their
                  respective affiliates. Any such set-off will be without
                  prejudice to PQC's right to pursue any other remedies at law
                  or in equity available to it.

                                  ARTICLE VII
                              GENERAL PROVISIONS

         7.01     Amendment and Waiver. No amendment of any provision of this
                  --------------------
                  Agreement shall in any event be effective unless the same
                  shall be in writing and signed by the parties hereto. Any
                  failure of any party to comply with any obligation, agreement
                  or condition hereunder may only be waived in writing by PQC
                  and Flagship if such failure is by Physician and by Physician
                  if such failure is by PQC and Flagship, but such waiver shall
                  not operate as a waiver of, or estoppel with respect to, any
                  subsequent or other failure. No failure by any party to take
                  any action against any breach of this Agreement or default by
                  the other party shall constitute a waiver of such party's
                  right to enforce any provision hereof or to take any such
                  action.

         7.02     Notices. All notices, requests, demands and other

                              FLAGSHIP HEALTH, P.A.
                               SERVICES AGREEMENT

         This Agreement (this "Agreement") is made as of November 30, 1996 by
and between Physicians Quality Care, Inc., a Delaware corporation ("PQC"), and
Flagship Health, P.A., a Maryland professional association ("Medical Group").
(All capitalized terms not defined below in this Agreement shall have the
meanings set forth in Appendix A or B attached hereto.)

         WHEREAS, Medical Group has entered into a business arrangement with PQC
in order to help effectuate the parties' mutual vision of establishing a high
quality, competitive, cost-effective health care delivery system, as part of
which Medical Group and PQC will work together to enhance the efficiency of the
business aspects of Medical Group's practice, to promote the quality of care and
patient satisfaction, and to create sufficient economies of scale to permit
Medical Group to undertake risk-based managed care obligations;

         WHEREAS, Medical Group engages in the provision of medical and surgical
services through its physicians (each a "Medical Group Physician" and
collectively the "Medical Group Physicians"), who currently practice in a number
of divisions (each a "Pod"), each of which may have one (1) or more Practice
Locations; and

         WHEREAS, Medical Group wishes to retain PQC to provide or arrange for
comprehensive management, administrative and other support services to manage
Medical Group and each Pod in order better to serve its patients, enhance
efficiency, and improve financial results of operation of the Medical Group's
activities.

         NOW, THEREFORE, in consideration of the mutual covenants and premises
herein contained, the parties hereby agree as follows:

         1.       APPOINTMENT OF PQC; RETENTION OF CLINICAL AUTHORITY

         1.1.     Appointment and Authority. Medical Group hereby appoints and
                  -------------------------
engages PQC as Medical Group's sole and exclusive business manager and PQC
accepts such appointment and engagement on and subject to the terms and
conditions set forth in this Agreement. Subject to the terms of this Agreement,
including applicable requirements of consultation and prior approval of the
Joint Policy Board, PQC shall have the authority and responsibility to: (i)
manage all business operations of Medical Group in an efficient and
cost-effective manner; (ii) provide or arrange for such services in any manner
as PQC, in the exercise of its reasonable business judgment, deems appropriate
to meet the day-to-day requirements of the business functions of Medical Group;
and (iii) negotiate and execute, on behalf of Medical Group, all contracts that,
in the exercise of PQC's reasonable business judgment, are necessary and
appropriate for the business and affairs of Medical Group, subject, in the case
of Payor Contracts, to the approval of the Joint Policy Board.

         1.2.     Retention of Authority.  Notwithstanding anything to the 
                  ----------------------
contrary in this Agreement, Medical Group will have exclusive authority and 
control over the provision of

                                       -1-
<PAGE>
 
medical services, including all diagnoses, treatment and ethical determinations
with respect to patients. All diagnoses, treatments, procedures and other
medical and professional services shall be provided and performed exclusively by
or under the supervision of a physician employed or otherwise engaged by Medical
Group who meets the qualifications set forth in this Agreement. It is
acknowledged that PQC is not authorized nor qualified to engage in any activity
that constitutes the practice of medicine. To the extent, if any, that any act
or service of PQC under this Agreement is determined to constitute the practice
of medicine, the performance of such act or service by PQC shall be deemed
waived and excused by Medical Group.

         2.   OBLIGATIONS OF MEDICAL GROUP

         2.1. Physician Personnel. Medical Group, subject to oversight by the
              -------------------
Medical Advisory Board, shall be solely responsible for all determinations with
respect to an individual physician concerning the recruitment, hiring,
termination, credentialing, training and supervision of such physician. PQC
shall not exercise any control over nor have any responsibility for Medical
Group Physicians or other Clinical Staff (as defined in Section 2.5) with
respect to the provision of clinical services.

         2.2. Credentialing of Medical Group Physicians. Medical Group, through
              -----------------------------------------
the Medical Advisory Board, shall credential its physicians in conformance with
the requirements imposed under state and federal law and by the terms of any
third party payment agreement to which the Medical Group is bound. Medical Group
shall assure that each Medical Group Physician at all times is: (i) duly
licensed to practice medicine by the applicable state within the Geographic Area
(as defined in Section 10.8 of Appendix A); and (ii) a member in good standing
of the medical staffs of hospitals designated from time to time by the Joint
Policy Board or as may be necessary in connection with the participation in one
(1) or more Payor Contracts negotiated on Medical Group's behalf by PQC. No
physician other than those Medical Group Physicians who meet the requirements
and qualifications of this Agreement, including without limitation Section 2.3,
shall be permitted: (a) to use or occupy the Pod Practice Locations, except as
approved by the Joint Policy Board; or (b) except as may be required to assure
appropriate medical care (e.g., locum tenens coverage), to render services to
patients of Medical Group. New physicians may be employed by Medical Group, or
physician groups or practices may be acquired by Medical Group, subject to
approval of the Joint Policy Board and the Medical Advisory Board.

         2.3. Employment and Engagement of Medical Group Physicians.
              -----------------------------------------------------

         (a)  General. During the term of this Agreement, Medical Group, through
              -------
              its Pods, shall operate and maintain a full-time practice of
              medicine providing primary care, medical and surgical specialty
              services and such other services as are agreed upon by the Joint
              Policy Board and PQC. Medical Group shall engage a sufficient
              number of Medical Group Physicians to provide services to patients
              of Medical Group during the normal office hours of the Practice
              Locations and to provide after hours coverage for all patients of
              Medical Group whether on an inpatient or outpatient basis;
              provided, however, that a Pod may close its practice to new
              patients for such period as the Joint Policy

                                       -2-
<PAGE>
 
              Board may determine to be necessary in the event the Pod has 
              reached capacity.

         (b)  Pods. Each Medical Group Physician hired or otherwise engaged by
              -----
              Medical Group shall be a member of a Pod and shall provide
              services at the Practice Locations associated with that Pod.

         (c)  Form of Agreements. Medical Group shall maintain employment
              -------------------
              agreements with all Medical Group Physicians (individually, an
              "Employment Agreement"). Such Employment Agreements shall be in
              substantially the form attached hereto as Annex A with such
              changes as may be agreed upon by PQC and Medical Group and
              approved by the Joint Policy Board. Except as otherwise expressly
              provided in this Agreement, Medical Group shall not amend any
              Employment Agreements nor waive any rights thereunder without the
              prior written approval of PQC. Except as otherwise expressly
              provided in this Agreement, Medical Group shall not offer, agree
              to or amend any salary, benefit or other compensation terms with a
              Medical Group Physician except as expressly approved by PQC in
              writing.

         (d)  Medical Group Physician Qualifications. Medical Group shall assure
              --------------------------------------
              that each Medical Group Physician meets at all times each of the
              qualifications set forth in the approved form of Employment
              Agreement in addition to any other qualifications reasonably
              established by the Medical Advisory Board and PQC. In the event
              that any disciplinary, malpractice or other actions are initiated
              against any Medical Group Physician, the Medical Group, through
              the Medical Advisory Board, shall immediately inform PQC of such
              action and shall inform PQC of the underlying facts and
              circumstances.

         2.4. Licensing and Accreditation. Medical Group, through the Medical
              ---------------------------
Advisory Board, shall ensure that all Medical Group Physicians maintain such
licenses and certifications as are reasonably necessary for the provision of
medical services by Medical Group and all Medical Group Physicians in a manner
that complies with all laws and applicable third-party payor requirements.
Medical Group shall obtain and maintain such additional licenses and
accreditations as the Medical Advisory Board and PQC mutually determine are
advisable. Medical Group shall conduct its medical practice in compliance with
all applicable laws and all applicable contractual requirements.

         2.5. Supervision and Direction of Clinical Staff. (As used in this
              --------------------------------------------
Agreement, the term "Clinical Staff" shall mean nurses and any other
non-physician clinical personnel and shall not include Medical Group Physicians
or any other physician.) Medical Group Physicians shall supervise and direct the
Clinical Staff. Medical Group shall assure that all Clinical Staff members
perform only those duties permitted by applicable law and regulation to be
performed by such personnel, and only under such supervision and in such a
manner as permitted by applicable law and regulation.

         2.6. Liability Insurance.  Medical Group shall assure that each 
              --------------------
Medical Group Physician maintains in effect a policy of professional liability 
insurance in accordance with

                                       -3-
<PAGE>
 
the Medical Group Physician's employment agreement. Medical Group shall maintain
in effect a policy of comprehensive general liability and professional liability
insurance in the minimum amount of $1,000,000 per occurrence or claim and
$3,000,000 annual aggregate, or such greater amount as is required by the Joint
Policy Board or by law, to cover Medical Group, Medical Group Physicians and
Clinical Staff. In addition, Medical Group shall maintain in effect (i)
comprehensive general liability insurance with limits and a deductible
reasonably determined by PQC and the Joint Policy Board and (ii) property damage
insurance covering all Practice Locations and equipment with limits and
deductibles reasonably determined by PQC and the Joint Policy Board. Each such
policy shall name PQC as an additional insured. As set forth in Section 3.15,
PQC shall be responsible for administering Medical Group's insurance policies
required under this Section 2.6.

         2.7. Medical Records. Medical Group, through its Pods, shall maintain
              ----------------
and cause each Medical Group Physician to maintain accurate and complete patient
records in accordance with all applicable laws and regulations. Such records
shall be maintained by Medical Group in a manner sufficient to enable PQC, on
behalf of Medical Group, to bill and collect for the services provided by
Medical Group and Medical Group Physicians. Subject to the requirements of
applicable law, Medical Group shall permit PQC to access the patient records to
perform its duties under this Agreement, including, without limitation, billing
and collection services. All patient medical records relating to services
rendered by Medical Group and Medical Group Physicians shall be and remain the
property of Medical Group.

         Medical Group hereby grants to PQC the exclusive right to develop and
commercialize any statistical data base or other quality assurance, utilization
review or medical management data base or software program derived from Medical
Group's medical records (collectively, "Medical Data") and agrees to include in
all patient consent forms a mutually agreeable provision permitting the
commercialization of such Medical Data; provided, however, that PQC shall in all
events delete or otherwise disguise any patient identifying information such as
the name or street address of a patient and comply with all applicable laws
concerning patient confidentiality. If PQC determines to commercialize any
Medical Data derived solely from medical records of Medical Group, then PQC
shall offer to Medical Group a right of first refusal to participate in the
effort to commercialize such Medical Data on terms consistent with those set
forth in Section 3.17 with respect to the development of Integrated Health
Services. If PQC determines to commercialize any Medical Data derived from both
Medical Group and other PQC-managed physician practices, then prior to entering
into any arrangement to commercialize such Medical Data, PQC shall solicit the
advice of the Medical Advisory Board, which may make a recommendation to PQC's
National Medical Advisory Board, concerning an allocation of revenue from such
commercialization to Medical Group and any other medical group or entity also
contributing data or software to the commercialization effort in a manner that
is fair and not inconsistent with PQC's legitimate business objectives and its
obligations to its shareholders. The recommendation, if any, of the National
Medical Advisory Board shall be considered by PQC in reaching its determination
concerning any commercialization of Medical Data and the allocation of proceeds
thereof, but ultimate decision-making authority with respect to such
commercialization and any recommended allocation of proceeds thereof shall
remain exclusively within the discretion of the Board of Directors of PQC and
Medical Group shall

                                       -4-
<PAGE>
 
have no right to any allocation of proceeds except and to the extent, if any,
authorized by the Board of Directors of PQC after consultation as set forth in
this Section 2.7.

         2.8. Assignment of Intellectual Property. Medical Group hereby assigns
              ------------------------------------
to PQC (i) any Intellectual Property rights that Medical Group acquires or
develops during the term of this Agreement and (ii) agrees to cause each Medical
Group Physician to assign to PQC such Intellectual Property rights as may be
specified in, and subject to the terms of, the applicable employment agreement,
as the case may be.

         3.   OBLIGATIONS OF PQC

         3.1. General. Subject to Medical Group's control of the practice of
              --------
medicine, PQC shall have authority and responsibility to conduct, supervise and
manage the day-to-day business operation of Medical Group and shall be
responsible for providing the services set forth in this Section 3 to Medical
Group. All services, facilities, furniture, fixtures and equipment provided by
PQC under this Agreement shall be in a manner consistent with community
standards for a medical practice of similar size. Notwithstanding anything in
this Agreement to the contrary, the parties realize that development of
appropriate reporting systems for financial and utilization information and
similar tools designed to support the efficient management and development of
Medical Group should be a collaborative process between the parties, and
accordingly the parties agree to work together to develop such tools,
particularly during the initial months following the Effective Date.

         3.2. Facilities. PQC shall arrange for Medical Group to use the
              -----------
premises at the locations listed on Schedule 2 which may be amended by PQC from
                                    ----------
time to time (collectively, the "Practice Locations"), subject to the terms of
any leases for the premises entered into from time to time by Medical Group or
PQC, as the case may be, and subject to approval of the Joint Policy Board. PQC
shall provide or arrange for routine maintenance and cleaning services for the
Practice Locations required to cause the Practice Locations to satisfy the
standard set forth in Section 3.1.

         3.3. Equipment and Office Furnishings. PQC shall arrange for Medical
              ---------------------------------
Group to have use of such equipment and office furnishings reasonably deemed
necessary by PQC, in consultation with the Joint Policy Board, for the operation
of Medical Group at each Practice Location (the "Equipment") in a manner
consistent with community standards for a medical practice of similar
characteristics. PQC shall arrange for reasonable and necessary repair and
maintenance of the Equipment. In connection with PQC's obligation hereunder,
Medical Group shall notify PQC immediately upon becoming aware of any Equipment
in need of repair.

         3.4. Personnel and Payroll. PQC shall arrange for the provision to
              ----------------------
Medical Group of all administrative personnel deemed necessary by PQC, in
consultation with the Joint Policy Board, for the operation of Medical Group
(the "Administrative Staff"). PQC shall also arrange for the provision to
Medical Group of all Clinical Staff reasonably deemed necessary by PQC, in
consultation with Medical Group and the Joint Policy Board, for the efficient,
professional operation of Medical Group. All members of the Clinical Staff shall
be employees of Medical Group. All members of the Administrative Staff on the
Effective Date

                                       -5-
<PAGE>
 
shall be employees of Medical Group. Subject to the provisions of Section 2.5
and this Section and in consultation with Medical Group and the Joint Policy
Board, PQC shall be responsible for recruiting, hiring, discharging and
determining the compensation, benefits and conditions of employment of the
Administrative Staff and Clinical Staff. PQC shall perform all payroll and
payroll accounting transactions for the Administrative Staff, the Clinical Staff
and the Medical Group Physicians. Any member of the Administrative Staff and
Clinical Staff may, upon assignment by PQC following consultation with the
affected Pods, provide services to more than one (1) Pod. If any Medical Group
Physician is dissatisfied with the services of any employee who provides
services for such Medical Group Physician at a Practice Location, PQC, after
consultation with the Joint Policy Board, shall in good faith determine whether
the performance of that employee could be brought to acceptable levels through
counsel and assistance, or whether the employment of such employee should be
terminated. If PQC determines to retain such employee and the Medical Group
Physician is still dissatisfied with such employee's services after a two (2)
month period, PQC shall either relocate such employee or otherwise cease to use
such employee unless PQC reasonably determines that such termination may expose
Medical Group to liability.

         3.5.     Borrowings.
                  -----------
         (a)      All borrowings of Medical Group shall be subject to prior
                  approval by the Joint Policy Board. Upon receipt of such
                  approval to borrow funds on behalf of Medical Group, PQC shall
                  arrange for such borrowing on behalf of Medical Group on terms
                  approved by the Joint Policy Board pursuant to Section 6.
                  1(b)(i) and in accordance with the Practice Expense definition
                  set forth provisions in Section 10.22 of Appendix A. In
                  addition to or in lieu of the foregoing, and subject always to
                  prior approval by the Joint Policy Board, PQC may in its sole
                  discretion make loans to Medical Group from time to time to
                  fund capital expenditures or working capital of the Medical
                  Group, in each case on such terms and conditions as are agreed
                  upon by the parties and the Joint Policy Board.

         (b)      In the event that during the Fiscal Periods ended December 31,
                  1997 and December 31, 1998, Medical Group does not receive
                  distributions under Appendix B hereto equal to the full
                  Baseline Amount (as defined in Section 10.2 of Appendix A)
                  (minus the amount necessary to pay all Deductible Expenses);
                  due to (a) a failure by PQC to assist Medical Group in
                  establishing additional revenue sources from services other
                  than professional services so as to increase Practice
                  Revenues, or (b) such other cause as may be approved by the
                  Joint Policy Board, PQC shall loan to Medical Group an amount
                  not to exceed an aggregate of $1,000,000 at any one time
                  outstanding on a non-interest bearing basis to cover such
                  shortfalls in Baseline Amount, and in no event shall PQC
                  Direct Expenses be included in determining whether a shortfall
                  in Baseline Amount exists (the "Loan"). The Loan shall be
                  carried on the balance sheet of Medical Group and shall be
                  repaid in successive Fiscal Periods from the first available
                  dollars of Net Margin allocable to Medical Group. In the event
                  PQC undertakes a public offering of securities at any time

                                       -6-
<PAGE>
 
                  prior to which the Loan has been repaid in full, the parties
                  agree to consider in good faith whether interest on the Loan
                  should be assessed at a fair market interest rate in order to
                  comply with then applicable health care laws.

         3.6. Supplies and Inventory. PQC shall be responsible for all inventory
              ----------------------
systems of Medical Group at each Practice Location and for the ordering,
purchasing and maintenance of all supplies and inventory necessary for the
operation of Medical Group. All drugs shall be purchased and maintained by
Medical Group or, at PQC's discretion and to the extent consistent with
applicable law, on behalf of Medical Group by PQC.

         3.7. Contracts. PQC shall negotiate and administer contracts for
              ----------
equipment, materials, supplies and data processing services for the Medical
Group and for each Pod. PQC shall seek, review, evaluate and negotiate Payor
Contracts on behalf of Medical Group. Medical Group agrees to enter into and be
bound by all such Payor Contracts negotiated on its behalf by PQC; provided,
however, that any such Payor Contract must be approved in advance by the Joint
Policy Board. If required by applicable law, such contracts will be entered into
in the name of Medical Group. PQC shall arrange for administrative support
appropriate to fulfill reporting requirements under Payor Contracts, such as
eligibility verification and financial and utilization reporting.

         3.8. Budgets.
              --------

         (a)      General Preparation Principles.
                  -------------------------------

                  (i)      PQC, acting through the Operating Manager in
                           cooperation with a Physician representative (the
                           "Representative") of the Pod, shall have
                           responsibility for the preparation of budgets for
                           each Pod (a "Pod Budget").

                  (ii)     Each Pod Budget shall consist of an operating budget
                           (revenues and expenses) and an annual capital
                           expenditures budget, prepared on an accrual basis of
                           accounting and in conformity with generally accepted
                           accounting principles.

                  (iii)    PQC shall prepare, with input from the Joint Policy
                           Board, budget guidelines ("Budget Guidelines") that
                           PQC shall then follow in the preparation of each Pod
                           Budget. Examples of possible Budget Guidelines
                           include but are not limited to the following:

                                    (A)     each Pod Budget shall be constructed
                                            on management policies that enable
                                            the Pod to achieve its financial
                                            goals (profit from operations);

                                    (B)     each Pod Budget shall provide
                                            specific detail sufficient for the
                                            Pod Physicians and PQC to evaluate
                                            and prioritize changes in programs
                                            and capital expenditures;

                                       -7-
<PAGE>
 
                                (C)     each Pod Budget period shall be for a
                                        twelve (12) month period ending December
                                        31 or, for the initial Pod Budget for
                                        each newly formed Pod, such shorter
                                        period ending December 31 as is
                                        appropriate; and

                                (D)     each Pod Budget shall be prepared on a
                                        pre-physician compensation, pre-
                                        management fee and pre-tax basis.

                  (iv)     PQC shall prepare the initial Pod Budgets for each
                           Pod using available historical financial information.
                           PQC shall follow the Budget Guidelines and identify
                           budget preparation assumptions that deviate from the
                           acquired medical group's historical financial
                           information. Subsequent Pod Budgets shall be prepared
                           in a similar manner by PQC (on the basis of the prior
                           year's results) and take into account deviations from
                           the Pod Budget that occurred in the prior year.

         (b)      Approval of Budgets. The Joint Policy Board shall have the
                  --------------------
                  responsibility for and authority to approve each Pod Budget.
                  PQC shall submit each Pod Budget to the Joint Policy Board for
                  approval on a timely basis. Once approved in accordance with
                  this Section 3.8(b), all of PQC, Pod and Pod Physicians shall
                  be bound by the terms of the approved Pod Budget for the
                  following twelve (12) month period or such lesser period as
                  may be provided for in the Budget Guidelines, subject only to
                  any modifications suggested by PQC and/or Pod Physicians and
                  approved by the Joint Policy Board. At any point during a
                  Fiscal Period, including for example if the actual Physician
                  Pod Practice Revenues less actual Physician Pod Practice
                  Expenses is below budgeted levels for such Physician Pod or if
                  there is an actual or projected negative Net Margin the Joint
                  Policy Board may review the budgets for such Physician Pod and
                  make such changes to such budgets, including the aggregate Pod
                  Distributions (as defined in Section 3 of Appendix A to the
                  Employment Agreements), as the Joint Policy Board deems to be
                  appropriate. All capital and operating budgets, and changes
                  thereto, also shall be subject to the approval of PQC. The
                  Joint Policy Board shall not unreasonably withhold its
                  approval of a Pod Budget but if such approval is not
                  forthcoming, the following process shall prevail so that the
                  Pod may remain open to treat patients:

                  (i)      If, prior to the commencement of any budget period,
                           the Joint Policy Board has not yet approved the Pod
                           Budget, then PQC and Medical Group will work
                           diligently in good faith to obtain such approval.
                           Until such approval is obtained, the following
                           procedures shall apply:

                                    (A)     as to any disputed line items, the
                                            immediately preceding budget
                                            period's Pod Budget shall be
                                            controlling until such time, if any,
                                            as agreement is reached on the
                                            amounts to be allocated to such
                                            disputed line items, except that:

                                       -8-
<PAGE>
 
                                     (1)    non-recurring extraordinary items
                                            shall not be continued from the Pod
                                            Budget for the immediately preceding
                                            budget period;

                                     (2)    if items such as lease payments or
                                            payroll taxes are subject to an
                                            automatic increase, such increases
                                            shall be effective at the increased

Affiliates proposes to provide any Integrated Health Service in the Geographic
Area, PQC shall notify Medical Group and the Joint Policy Board of the nature of
the service and the terms upon which PQC or its Affiliate proposes to provide
the service, and the Joint Policy Board, on behalf of Medical Group, shall have
forty-five (45) days during which to elect to participate in the provision of
such Integrated Health Service in the Geographic Area on such terms as are
mutually acceptable to Medical Group and PQC. Any such proposal shall specify
the proposed manner in which the net revenues (meaning all receipts from such
Integrated Health Services less all expenses attributable to such Integrated
Health Services, determined in accordance with generally accepted accounting
principles) shall be allocated between Medical Group and PQC, but to the extent
permitted by law in any event such proposal shall offer to Medical Group the
right to receive an allocation to the Variable Distribution Pool (as defined in
the Employment Agreements) of at least fifty percent (50%) of the net revenues
attributable to such Integrated Health Service provided that as a condition
thereof Medical Group shall agree that a percentage of any net loss attributable
to such Integrated Health Service equal to the percentage of net revenues
attributable to such Integrated Health Service shall be offset against amounts
otherwise allocable to Medical Group under Appendix B in any one (1) or more
Fiscal Periods thereafter occurring. Medical Group shall not agree to
participate in any Integrated Health Service or fail to elect to participate in
such Integrated Health Service except as approved by and on such terms as have

participate in such Integrated Health Service in the Geographic Area within such
forty-five (45) day period, PQC may, but shall not be obligated to, provide such
Integrated Health Service directly or through another Affiliate or subsidiary
(but in no event through or with any outside third party without the prior
consent of the Joint Policy Board) and Medical Group shall have no right to
participate in the revenues or income from such Integrated Health Service;
provided, however, that PQC shall not directly or indirectly provide such
Integrated Health Service if within such forty-five (45) day period the Medical
Advisory Board reasonably determines and notifies PQC that the provision of such
services have not been determined to be clinically efficacious, are clinically
dangerous, or would otherwise adversely affect the reputation of PQC and/or
Medical Group as to quality of care.

                  Members" means only those Medical Group Physicians whose
                  Employment Agreement permits them to share in Net Revenues as

                  of nine (9) individuals: four (4) elected by plurality vote of
                  the Physician Members (the "Medical Group Representatives"),

                  (4) appointed by PQC (the "PQC Representatives"), and the
                  President of Medical Group (who shall serve ex-officio with
                  vote). Each Medical Group Representative shall be a physician
                  selected for a three (3) year term by Physician Members. Each
                  Medical Group Representative may serve an unlimited number of
                  terms and shall serve until a successor is selected. The PQC
                  Representatives shall be appointed from time to time by PQC.
                  The Medical Group Representatives shall select, from among the
                  physicians who are members of the Joint Policy Board, the

                  and, to the extent expressly provided in this Agreement, shall
                  have the right to approve certain decisions by Medical Group
                  and PQC. Any amendment of this Agreement that would limit or

                  of the Joint Policy Board, including without limitation any
                  changes to this Section 6 or Appendix B, shall require the
                  prior approval of the Joint Policy Board. In addition, the
                  following actions shall require the affirmative vote of a
                  majority of the members of the Joint Policy Board:

                           majority of the members of the Joint Policy Board. A
                           quorum of the Joint Policy Board shall consist of at

                           of the Joint Policy Board by the attendance at such

physicians and who shall be Physician Members, for the position of President,
and the Medical Group Shareholder shall select one (1) candidate from among such

of President at any time for any reason, the Medical Group Shareholder shall
have the authority to appoint a person to serve as interim President until

procedures. The President shall serve part-time in this capacity until such time
as his responsibilities warrant full-time employment status. Notwithstanding the
foregoing, the President shall be a Medical Group Physician active in the

Shareholder for an interim period only until a successor to the position of
President has been appointed in accordance with the provisions of this Section
6.3(b). Medical Group shall assist in the development of procedures for the

ensure a smooth transition period in the medical practice of any individual who

                  fringe benefits of the Medical Director.

         (b)      Subject to the By-Laws of Medical Group (which shall not be 
                  amended to reduce the rights of the Medical Group under this
                  Section without the prior consent of a majority of Physician
                  Members), the Physician Members shall nominate by plurality
                  vote three (3) candidates who shall be Physician Members for

                  Shareholder shall select one (1) candidate from among such

                  any reason, the Medical Group Shareholder shall have the
                  authority to appoint a person to serve as interim Medical
                  Director until another person is duly appointed in accordance
                  with the above specified procedures. The Medical Director
                  shall serve part-time in this capacity until such time as his
                  responsibilities warrant full-time employment status.
                  Notwithstanding the foregoing, the Medical Director shall be a
                  Medical Group Physician active in the practice of medicine,
                  until such time as the Medical Director's responsibilities
                  warrant full-time employment status with the Medical Group.
                  The Medical Director shall serve for an initial period of two
                  (2) years, which may be renewed for a maximum of two (2)
                  additional two (2) year terms, subject to the control of and
                  review by Medical Group. Medical Group shall assist in the
                  development of procedures for the nomination, appointment and
                  replacement for the Medical Director in such a manner as to
                  ensure a smooth transition period in the medical practice of
                  any individual who assumes the position of the Medical
                  Director. The Physician Members shall have the right to remove
                  the Medical Director upon a two-thirds (2/3) vote of all
                  Physician Members, but in such event the position of Medical
                  Director may be filled only in accordance with the provisions
                  of this Section 6.4(b).

shall manage and administer all of the

<PAGE>
 
day-to-day business transactions necessary for the operation of Medical Group.

the Operating Manager shall implement the policies established by Medical Group
and the Joint Policy Board and shall generally perform the duties and have the
responsibilities of an administrator.

         7.   INTELLECTUAL PROPERTY

         Medical Group acknowledges that PQC will continually develop
Intellectual Property and that Medical Group may have access to and use
Intellectual Property during the term of this Agreement. Medical Group agrees
that, except as required for the proper operation of the medical practice in
accordance with applicable law and the terms of this Agreement, it will not,
directly or indirectly, use or disclose any Intellectual Property. Medical Group
understands and agrees that this restriction will continue to apply after the
termination of this Agreement for any reason.

         Medical Group agrees that all Intellectual Property to which it has
access as a result of its relationship with PQC under this Agreement is and
shall remain the sole and exclusive property of PQC. Except as required for the
proper operation of the medical practice in accordance with applicable law and
the terms of this Agreement, Medical Group will not copy any documents, tapes or
other media containing Intellectual Property ("Documents"). Medical Group will
return to PQC immediately after this Agreement terminates, and at such other
times as may be specified by PQC, all Documents and copies of Documents. Medical
Group shall use its best efforts to assure that all Medical Group Physicians and
other employees and agents of Medical Group are aware of and comply with the
restrictions on disclosure and use of Intellectual Property set forth in this
Section. (For purposes of this Section, references to PQC shall be deemed to
refer to PQC and any Affiliates.)

         8.   RESTRICTIVE COVENANTS

         The parties recognize that the services to be provided by PQC hereunder
shall be feasible only if Medical Group operates an active medical practice to
which the physicians associated with Medical Group devote their full time and
attention. Accordingly, the parties hereto agree as follows:

         8.1. Noncompetition. During the term of this Agreement, Medical Group
              ---------------
shall not, without the prior written consent of PQC, establish, operate or
provide physician or other medical services at any medical office, clinic or
other health care facility providing services similar to those provided by
Medical Group, PQC or any Affiliate of PQC, within the Geographic Area.

         8.2. Ancillary Enterprise. During the term of this Agreement, except as
              ---------------------
permitted by this Agreement, Medical Group shall not provide any of the
additional services that have been approved by the Joint Policy Board and PQC as
"Integrated Health Services" or any other services provided by PQC. For two (2)
years after termination of this Agreement, except as permitted by this
Agreement, Medical Group shall not provide any of the additional services that
have been approved by the Joint Policy Board and PQC as

                                      -20-
<PAGE>
 
"Integrated Health Services" or any other services provided by PQC, within
fifteen (15) miles of any Pod Practice Location.

         8.3. Non-solicitation of Employees and Patients. During the term of
              -------------------------------------------
this Agreement and for a two (2) year period thereafter, Medical Group shall not
recruit, solicit or induce or attempt to induce, any employee or employees of
Medical Group or PQC to terminate their employment with, or otherwise cease
their relationship with, Medical Group or PQC. During the term of this Agreement
and for a one (1) year period thereafter, Medical Group shall not solicit,
attempt to divert or to take away, the business or patronage of any of the
patients, clients, customers or accounts, or prospective patients, clients,
customers or accounts of Medical Group.

         8.4. Enforcement of Medical Group Physician Employment Agreements.
              -------------------------------------------------------------
Medical Group shall enforce the Employment Agreements of Medical Group
Physicians, including, without limitation, restrictive covenants and liquidated
damages provisions contained in such agreements. In the event that, after a
request by PQC, Medical Group does not pursue any remedy that may be available
to it by reason of a breach or default of the restrictive covenants and
liquidated damages provisions or any other provision of any Employment
Agreement, upon the request of PQC, and in addition to any rights PQC may have
under Section 9.13 hereunder, Medical Group shall assign to PQC such causes of
action and any other rights it has related to such breach or default and shall
cooperate with and provide reasonable assistance to PQC with respect thereto.

         8.5. Remedies. PQC and Medical Group acknowledge and agree that a
              ---------
remedy at law for any breach or attempted breach of the provisions of this
Section 8 shall be inadequate, and, therefore, either party shall be entitled to
specific performance and injunctive or other equitable relief in the event of
any such breach or attempted breach, in addition to any other rights or remedies
available to either party at law or in equity or under the Employment
Agreements, including without limitation provisions thereunder relating to the
repurchase by the Medical Group and/or the Medical Group Physicians of certain
assets. Each party hereto waives any requirement for the securing or posting of
any bond in connection with the obtaining of any such injunctive or other

conformable, so as not to affect the validity or enforceability of the remainder
of this Agreement.

         9.6. Waiver.  Failure of either party to enforce a right under 
              -------
this Agreement will not act as a waiver of that right or the ability to later

               --------------
accordance with the laws of the State of Maryland. Each of the parties hereto

obligation of PQC or of the Medical Group to, or any rights in, any person or
entity not a party to this Agreement. Notwithstanding the foregoing, in
accordance with and subject to the terms of the provisions of the Employment
Agreements between the Medical Group Physicians and Medical Group, the Medical
Group Physicians are hereby made third party beneficiaries of and may enforce
the obligations of PQC hereunder (as the same may be amended from time to time

amended by the parties in accordance with Section 9.9 without the consent of the
Medical Group Physicians.

         9.14. Contract Modifications for Prospective Legal Events. In the event
               ----------------------------------------------------
(a) any state or federal laws or regulations, now existing or enacted or
promulgated after the Effective Date are interpreted by judicial decision, a
regulatory agency, or legal counsel with a nationally recognized expertise in
the field of law in question in such a manner as to indicate that this Agreement
or any provision hereof may be in violation of such laws or regulations, or (b)
the Financial Accounting Standards Board, Emerging Issues Task Force or other
applicable accounting standard setting entity promulgates standards or issues a
consensus that would prevent PQC from consolidating for financial statement
presentation purposes all Practice Revenues of Medical Group on PQC's
consolidated financial statements, then PQC

                                      -23-
<PAGE>
 
shall propose to the Joint Policy Board and Medical Group for their approval
such amendments to this Agreement as necessary to conform the Agreement to all
applicable law and preserve the underlying economic and financial arrangements
between PQC and Medical Group without substantial economic detriment to either
PQC or Medical Group. Any such amendment approved by the Joint Policy Board and
Medical Group shall be binding upon Medical Group, and Medical Group hereby
consents to any such amendment. To the extent any act or service required of PQC
should be construed or deemed, by any governmental authority, agency or court,
to constitute the practice of medicine by PQC, the performance of said act or
service by PQC shall be deemed waived and forever unenforceable and the
provisions of this Section 9.14 shall be applicable. To the fullest extent
permitted by law, Medical Group hereby waives and agrees not to 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 9.14.

         9.15. Availability of Certain Documents. The parties agree, to the
               ----------------------------------
extent required by law necessary to permit receipt of reimbursement for services
by Medical Group, to make available to the Secretary of Health and Human
Services, the Comptroller General of 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.

                             FINANCIAL ARRANGEMENTS

         ARTICLE A.   COMPENSATION TO PQC
                      -------------------

         1. General. As set forth in greater detail below and subject to all of
            --------
the conditions and provisions hereof, the parties agree that the aggregate
compensation to be paid to PQC for services rendered under this Agreement shall
equal the sum of (1) all PQC Direct Expenses incurred in connection with the
provision of services to Medical Group and (2) additional compensation equal to
fifty percent (50%) of Net Margin of the Medical Group. This Appendix B also
provides for the priority of application of Practice Revenues to various
categories of expenditures.

         2. Application of Practice Revenues.
            ---------------------------------
         Practice Revenues shall be applied to expenses and other required
distributions under this Agreement in the following order of priority:

                                  (a)      Step 1 - Practice Revenues shall be
                                           ------
                                           applied to pay Practice Expenses.

                                  (b)      Step 2 - Any Gross Margin
                                           ------
                                           remaining after Step 1 above shall
                                           next be applied to payment of (i)
                                           the Baseline Amount (minus the
                                           amount necessary to pay all
                                           Deductible Expenses) and (b) PQC
                                           Direct Expenses on a proportional
                                           basis equal to the ratio of the
                                           Baseline Amount to PQC Direct
                                           Expenses as approved by the Joint
                                           Policy Board for the then current
                                           Fiscal Period or in the absence of
                                           approval of a budget for the then
                                           current Fiscal Period, in the ratio
                                           set forth on Schedule B-1 attached
                                           to this Agreement.  By way of
                                           example only and not as a
                                           limitation, if the Baseline Amount is
                                           $12 million and budgeted PQC
                                           Direct Expenses are $1 million, then
                                           under this Step 2 12/13ths or
                                           92.31% of each dollar of Gross
                                           Margin shall be allocated to
                                           Medical Group for payment of the
                                           Baseline Amount and the remaining

                                       B-1
<PAGE>
 
                                           1/13th or 7.69% of each dollar of
                                           Gross Margin shall be allocated to
                                           PQC.

                                  (c)      Step 3 - After completion of Step 2,
                                           ------
                                           any remaining Net Margin shall be
                                           allocated fifty percent (50%) to
                                           Medical Group for distribution to the
                                           Medical Group Physicians and fifty
                                           percent (50%) to PQC as additional
                                           compensation hereunder.

         Subject to review by the Joint Policy Board, PQC shall calculate the
amounts of Gross Margin and Net Margin to be allocated to each of Medical Group
and PQC under this Section 2. If the Gross Margin is negative in any Fiscal
Period, such negative amount shall constitute Practice Expenses for the next
following Fiscal Period. In the event Net Margin is negative in the Fiscal
Periods ending December 31, 1997 or December 31, 1998, PQC may be obligated to
make a loan to Medical Group in accordance with the provisions of Section 3.5 of
the Agreement.

         3. Payment of Physician Draw. On a bi-weekly basis, PQC shall
            --------------------------
distribute to Medical Group from the account referred to in Section 3.12 of this
Agreement ("Medical Group Account") an amount equal to one twenty-sixth of the
budgeted aggregate Physician Draw (minus the amount necessary to pay all
Deductible Expenses) for distribution by Medical Group to the Pods; provided,
however, if (a) at any time during a Fiscal Period, PQC determines that the
amount of Practice Revenues allocated to the payment of aggregate Physician Draw
under Section 2 of this Appendix B for any Fiscal Period may be less than
ninety-five percent (95%) of the budgeted aggregate Physician Draw for such
Fiscal Period, or (b) if PQC or the Joint Policy Board determines (1) the
aggregate Practice Expenses for such Fiscal Period will exceed the aggregate
budgeted Practice Expenses for such Fiscal Period, or (2) the aggregate Practice
Revenues will be less than the aggregate budgeted Practice Revenues, PQC may,
and upon direction from the Joint Policy Board, shall, reduce the aggregate
Physician Draw in such manner as PQC determines to be appropriate. Subject to
the provisions of Section 3.5 of this Agreement, the aggregate Physician Draw
shall be adjusted to reflect the addition of new Medical Group Physicians or the
termination or resignation of any Medical Group Physician or to reflect such
other factors as PQC and the Joint Policy board shall mutually agree to be
appropriate. PQC may, but shall not be required to, advance money to the
Compensation Pool as defined in Appendix A to the Employment Agreement to fund
such Physician Draw.

         4. Payment of Variable Distribution Pool. Within forty-five (45) days
            --------------------------------------
of the end of each of the first three (3) calendar quarters in each Fiscal
Period, PQC shall advise Medical Group's Compensation Committee (as defined in
Employment Agreements) of the amount (the "Variable Distribution"), if any, of
Net Margin allocable to Medical Group under Section 2 that has not been used, or
is not reasonably anticipated by PQC to be needed for Medical Group to fund, all
amounts required to be funded by Section 3. PQC shall disburse to Medical Group
from the account referred to in Section 3.12 of this Agreement the amount of

                                       B-2
<PAGE>
 
the Variable Distribution, which shall be distributed to the Physicians in such
manner consistent with law as is described in Section 4 of Appendix A to the
Employment Agreements.

         5. Annual Reconciliation of Distributions. Within sixty (60) days after
            ---------------------------------------
the end of each year, PQC shall (i) total and report Practice Revenues and
Practice Expenses for each Pod, (ii) total and report aggregate Practice
Revenues for all Pods and aggregate Practice Expenses for all Pods, (iii) total
and report PQC Direct Expenses, (iv) total and report all amounts advanced as
Physician Draws and Variable Distributions, (v) total and report the level of
Gross Margin, whether positive or negative, and (vi) total and report the level
of Net Margin, whether positive or negative (taking into account any adjustments
necessary in the event that distributions during the said Fiscal Period or any
prior Fiscal Periods have resulted in an over-advancement or under-advancement
of funds). Each Pod, as a Discretionary Expense of its Member Physicians, may
inspect Medical Group's books and records and PQC's books and records in order
to verify the amount and proper calculation of the sums to be determined
hereunder. PQC may not charge any Pod or Physician Member any access or similar
fee in connection with any request to review books and records. If such
independent accounting presents a report identifying a departure in such
financial reports from generally accepted accounting principles, which departure
has had a material adverse effect on the revenues allocated to Physician Group,
PQC shall reimburse the Physician Members for the cost of such report.

         6. Distribution in Event of Actual or Anticipated Negative Gross
            -------------------------------------------------------------
Margin. In the event that for any calendar quarter, Gross Margin is a negative
- -------
number or in the event either party gives notice to the other that there is
reason to believe Gross Margin may be a negative number, PQC shall promptly
propose a remedial plan of action to the Joint Policy Board and the parties
agree to cooperate in good faith in order to implement such remedial plan or
such other corrective action as shall be approved by the Joint Policy Board. At
PQC's sole discretion, PQC may elect to advance working capital funds to Medical
Group in such amounts and at such times, and from time to time, as PQC shall
determine necessary to satisfy aggregate Practice Expenses for all Pods, such
advances to be treated as loans, the repayment of which shall be required in
accordance with the definition of "Practice Expenses" in Section 10.22 of
Appendix A hereto. In the event PQC shall elect not to make advances sufficient
to satisfy aggregate Practice Expenses for all Pods and Medical Group has not
otherwise satisfied Practice Expenses from its own resources, either party shall
have the right to terminate this Agreement upon thirty (30) days' written
notice.

         7. Manner of Payment of Final Reconciliation. Within seventy (70) days
            ------------------------------------------
after the end of the Fiscal Period, Medical Group and PQC shall make such
payments, if any, to each other as may be required under the provisions of this
Appendix B. Medical Group covenants to distribute any amounts to the Physicians
in a manner that complies with all applicable law.

         8. Manner of Payment of PQC Direct Expenses and Compensation to PQC.
            -----------------------------------------------------------------
PQC shall arrange for the payment of PQC Direct Expenses and the compensation to
PQC itself in accordance with the terms of this Appendix and is hereby
authorized to make withdrawals from the Medical Group Account for such amounts
at the time or times that the amounts

                                       B-3
<PAGE>
 
become due. Medical Group hereby authorizes PQC to make such withdrawals from
the Medical Group Account for accrued but unpaid PQC Direct Expenses and
compensation owed to PQC under the provisions of this Appendix B after
termination of this Agreement.

            Group's expense) insurance under the professional liability policy
            or policies at a commercially reasonable cost for Physician's
            specialty as determined by Medical Group;

            programs and other carriers and managed care entities with which

            patients for care during such period, if any, as the Joint Policy
            Board shall have determined that Physician may reasonably close his

            regulations adopted from time to time by the Joint Policy Board;

                   (k)  promptly disclose to Medical Group the commencement or

                   (l)  abide by any reasonable guidelines adopted by the Joint
            Policy Board or, subject to the approval of the Joint Policy Board,
            any person or entity providing management services to Medical Group
            under the Services Agreement designed to encourage the appropriate,
            efficient and cost-effective delivery of medical services, subject
            always to the clinical judgment of Physician, and cooperate with and

            Advisory Board.

            3.3.   Outside Practice: Conflicts of Interest.
                   ----------------------------------------

                   (a)  Physician shall not, during the term of this Agreement,
            undertake any activity that interferes with, adversely affects, or
            represents a conflict of interest with Physician's obligations under
            this Agreement or that competes with Medical Group for patients, or
            (except as arranged by Medical Group) enter into any managed care
            contract or assume any liability under a risk pool or similar
            arrangement without Medical Group's consent. Physician shall, during
            the term of this Agreement, confine Physician's practice to Medical
            Group and its patients, except with respect to teaching and research
            activities approved by the Joint Policy Board. It is expressly
            understood and agreed that any medical services rendered by
            Physician to patients who express a wish to engage Physician
            personally shall be rendered by Physician as an employee of Medical
            Group.

                   (b)  Physician recognizes and agrees that the successful
            operation of Medical Group depends in large part upon the loyalty of
            Physician to Medical Group and upon the avoidance of conflicts of
            personal time and availability. Accordingly, as used in Section 1
            and in other sections of this Agreement, the term "fulltime" shall
            mean that Physician shall during the term hereof devote his full
            working time, attention, loyalty and best efforts to the affairs of
<PAGE>
 
            Medical Group, taking into account any vacation time and Continuing
            Medical Education time to which Physician is entitled and also
            taking into account any teaching, research, community activities,
            activities with professional organizations and care of indigent
            patients performed by Physician to the same extent that Physician
            historically has engaged in such activities. Upon the advance
            written approval of Medical Group, Physician may be relieved of
            Physician's obligation to provide services hereunder on a full-time
            basis for such professional purposes and such limited time period as
            may be so approved. Except to the extent the Joint Policy Board
            approves in writing Physician's retention of limited honoraria and
            similar amounts, any remuneration earned by Physician in connection
            with such approved professional activities shall be assigned to
            Medical Group; provided that no such exception shall take effect
            absent approval by the Joint Policy Board and PQC.

                   (c)  During the term of this Agreement, Physician shall not,
            and shall not undertake any planning (other than after the giving of
            notice under Section 8(d)(i)(C)) to, establish, operate or provide
            medical services to or practice medicine at any medical office,
            clinic or other health care facility other than pursuant to this
            Agreement, except as approved by Medical Group. 
                   
                   (d)  Physician understands and acknowledges that the
            foregoing provisions in this Section 3.3 are designed to preserve
            the goodwill of Medical Group and the goodwill of the other
            individual physicians of Medical Group. Accordingly, if Physician
            breaches any obligation of this Section 3.3, in addition to any
            other remedies available under this Agreement, at law or in equity,
            Medical Group shall be entitled to enforce this Agreement by
            injunctive relief and by specific performance of the Agreement, such
            relief to be without the necessity of posting a bond, cash or
            otherwise. Additionally, nothing in this paragraph shall limit
            Medical Group's right to recover any other damages to which it is
            entitled as result of Physician's breach.

            3.4.  Location of Practice. It is anticipated that Physician's
                  ---------------------
services hereunder will be performed at the location listed on Appendix C (the
"Practice Site"). In addition, Medical Group will consult with Physician before
assigning him to provide services at a different practice site, which assignment
may be made only with the approval of the Joint Policy Board and Physician.

            3.5.  Name.  Physician agrees that Medical Group shall be 
                  -----
entitled to use the name of Physician on a royalty free, non-exclusive basis for
the term of this Agreement, solely in connection with advertising for or
informational documents with respect to Medical Group or PQC.

            3.6.  Assignment of Intellectual Property. Physician agrees to
                  ------------------------------------
assign to PQC any Intellectual Property rights that Physician acquires during
the term of this Agreement; provided, however, that Physician shall not be
required to assign to PQC Intellectual Property rights that relate to (i)
non-medical studies and inventions, (ii) royalties from medical devices unless
developed as part of Physician's services to Medical Group, (iii) publications
on clinical aspects of a medical practice unless developed as a part of
Physician's services to Medical Group, (iv) medical books and articles designed
primarily for purchase by
<PAGE>
 
non-physicians, (v) any Intellectual Property developed by Physician prior to,
or in progress on, the date of this Agreement as disclosed on Schedule 3.6
hereto, and (vi) any Intellectual Property rights which Physician is, on the
date of this Agreement, obligated to assign to or share with the Johns Hopkins
Hospital, the Johns Hopkins University or any affiliated company or institution.
PQC will review the feasibility of commercializing any Intellectual Property
assigned to it pursuant to this Agreement. If PQC does not elect to
commercialize the Intellectual Property, it will reassign it to Physician. If
PQC elects to commercialize such Intellectual Property, PQC and Physician shall
enter into an agreement on mutually acceptable terms to share the costs and
revenues from such commercialization with Physician. Physician agrees for the
benefit of PQC, to execute, at PQC's expense, such further instruments or
agreements, to make such filing or registration and to take such other actions
as PQC determines to be necessary or desirable to give effect to the assignments
contemplated by this Section 3.6 or to protect, establish or record PQC's rights
to such Intellectual Property. Physician also agrees that PQC, the Joint Policy
Board and the Compensation Committee may consider the time devoted by Physician
to the development or promotion of Intellectual Property rights that are not
assigned to PQC in determining the operating budget of such Physician's
Physician Pod, including Physician Draw, and the allocation of the Compensation
Pool among Physician Pods.

         4. Compensation and Benefits.  Subject to performance of Physician's 
            --------------------------
duties and obligations to Medical Group pursuant to this Agreement or otherwise,
Physician shall be compensated as follows:

            4.1. Compensation.  As compensation for all services performed under
                 ------------
and during the term of this Agreement, Medical Group shall pay Physician in
accordance with the terms set forth on Appendix A, attached hereto and made a
                                       ----------
part hereof.

            4.2. Fringe Benefits. Physician shall be entitled during the
                 ----------------
term of this Agreement to participate in the employee fringe benefit plans
provided to other physician employees of Medical Group as set forth on 
Appendix B, attached hereto and made a part hereof, as amended from time to 
- ----------
time upon approval by the Joint Policy Board. Such participation shall be 
subject to (i) the terms of the applicable plan documents and (ii) generally 
applicable Medical Group policies.

             4.3. Professional Liability Insurance. During the term of this
                  ---------------------------------
Agreement, the Medical Group shall provide professional liability insurance
covering professional services provided by Physician in accordance with the
provisions of this Agreement with such limits of liability as determined by the
Joint Policy Board, which shall be initially not less than $1,000,000 per
occurrence and $3,000,000 annual aggregate. Medical Group's obligation to
provide such insurance is subject to Physician's compliance with any conditions
of such insurance other than the obligation to pay premiums.

         5. Warranties of Physician.  Physician represents and warrants that:
            ------------------------

                  (a)  Physician now possesses and will continue to possess 
         a valid and unlimited license to practice medicine pursuant to the laws
         of the State of Maryland;

                  (b)  Physician possesses a valid federal narcotics number

         papers;
<PAGE>
 
                  (c)  Physician's medical staff privileges at any hospital have
         never been (other than for delinquency in the completion of medical
         records) and are not in the process of being curtailed, suspended,
         revoked or otherwise the subject of any proceedings which can or could
         have resulted in the same;

                  (d)  Neither Physician's provider number for or eligibility to
         participate in Blue Shield, Medicare or Medicaid programs nor
         Physician's eligibility to participate in any other third-party payment
         system has ever been or is in the process of being curtailed,

         proceeding, whether civil, criminal or administrative in nature;

                  (g)  To the best of Physician's knowledge and belief,
         Physician is not now and never has been the subject of any
         investigation related to Physician's medical practice or qualifications
         for licensure as a physician other than that routinely conducted by a
         state' 8 board or agency with jurisdiction over the licensure of
         physicians in the usual course of initial and renewal licensure by the
         state; and

                  (h)  Physician's license to practice medicine in any state has
         never been revoked (not including revocation solely for non-payment of
         filing or renewal fees), suspended, restricted or otherwise curtailed
         nor has Physician been placed on probation by any medical licensing
         board.

         6. Charges.  Physician agrees that Medical Group, subject to the 
            --------
approval of the Joint Policy Board, shall set any and all charges to patients
for any professional services rendered by Physician during the term of this
Agreement.

         7. Billings, Assignment and Delivery of Revenues. As the employer of
            ----------------------------------------------
Physician, Medical Group has the right to bill for and to receive, hold, and
disburse all revenues (whether for professional services or ancillary services
such as laboratory services), generated by Physician. Physician hereby assigns,
and agrees to assign to Medical Group, all of his rights existing in said
revenues due on account of services rendered pursuant to this Agreement.
Physician acknowledges Medical Group's engagement of Physicians Quality Care,
Inc., a Delaware corporation pursuant to the Services Agreement, under which
Medical Group has authorized PQC to take those actions described below in this
Section 7 for and on behalf of and in the name of Medical Group and, as
necessary, for and on behalf of and in the name of Physician.

         If for any reason PQC cannot, on behalf of and in the name of Medical
Group, bill for and receive fees generated by any clinical services provided by
Physician, Physician hereby grants to PQC an exclusive power of attorney and
appoints PQC its exclusive true and lawful attorney-in-fact to take those
actions described below in this Section 7, including without
<PAGE>
 
limitation to bill for such services on behalf of Physician under Physician's
individual provider number or numbers.

         Physician acknowledges that, pursuant to the terms of the Services
Agreement, PQC shall:

                  (a)  bill in Medical Group's name, under its provider 
         number(s) when obtained within guidelines approved by the Joint Policy
         Board, and on its behalf, and

                  (b)  until such time as Medical Group has obtained its
         provider number(s), may bill in Physician's name, all claims (including
         co-payments due from patients) for reimbursement from Payors, as
         defined below, fiscal intermediaries or patients for all covered
         medical services provided by Physician or Medical Group to patients;

                  (c)  take possession of and endorse in the name of Physician
         or Medical Group all cash, notes, checks, money orders, insurance
         payments, and any other instruments received as payment of accounts
         receivable (and Physician covenants to transfer and deliver promptly to
         PQC all funds received by Physician from patients or Payors for medical
         services), all such funds to be deposited directly into a Medical Group
         account and to be applied in a manner consistent with the Services
         Agreement;

                  (d)  deposit all collections directly into a Medical Group
         account with a banking institution selected by PQC and approved by
         Medical Group and to make withdrawals from such Medical Group account
         for such purposes as are consistent with the Services Agreement;

                  (e)  collect and receive in: (i) Medical Group's name and on
         its behalf, and (ii) Physician's name and on his behalf, all accounts
         receivable generated by such billings and claims for reimbursement and
         to place such accounts for collection, settle and compromise claims,
         and institute legal action for the recovery of accounts; and

                  (f)  sign checks on behalf of the Medical Group and make
         withdrawals from Medical Group accounts for payments specified in the
         Services Agreement and as requested from time to time by Medical Group.

         Physician shall cooperate fully with Medical Group and PQC (1) in
facilitating such collections and (2) in collecting accounts receivable
transferred to PQC by Physician pursuant to this Agreement, including
endorsement of checks and delivery to PQC of all revenues, in whatever form,
received from patients or Payors on their behalf, and completion of all forms
necessary for the collection of said revenue, including, without limitation,
executing and delivering to each financial institution wherein Medical Group or
PQC maintains an account, such additional documents or instruments as may be
necessary to evidence or effect the power of attorney granted hereby to PQC. If
PQC assigns said power of attorney, then Physician shall execute a power of
attorney in favor of the assignee in a form acceptable to PQC.

         For purposes of this Section 7, "Payors" shall mean any persons that,
on behalf of a patient or enrollee or employee, pay or reimburse Physician or
Medical Group for providing health care services or for managing the provision
of health care services, such as insurance companies, managed care plans,
employers or the Medicare and Medicaid programs. The
<PAGE>
 
provisions of this Section 7 shall survive the termination of this Agreement.

         8. Termination. This Agreement shall terminate or be terminable at the
            ------------
end of the Employment Period, as it may be extended, or under any of the
circumstances set forth below. The "Termination Date" shall be the date as of
which all notice and cure periods, if any, have lapsed with respect to the
applicable provision under which either party is seeking to terminate this
Agreement.

            (a) Death  In the event of Physician's death, this Agreement 
                -----
         shall immediately and automatically terminate.

            (b) Disability. Either Medical Group or Physician may terminate this
                ----------
         Agreement, upon written notice to the other party, in the event that
         Physician becomes disabled through any illness, injury, accident or
         condition of either a physical or psychological nature and, as a
         result, is unable to perform substantially all of Physician's duties
         and responsibilities hereunder for ninety (90) consecutive days during
         any period of three hundred sixty-five (365) calendar days and Medical
         Group determines that there is no reasonable likelihood that Physician
         will be able to return to the performance of substantially all of
         Physician's duties and responsibilities on a regular basis within
         thirty (30) days thereafter; provided, however that the Joint Policy
         Board must approve any decision by the Medical Group to terminate a
         Physician pursuant to this Section 8(b), which approval shall not be
         unreasonably withheld. If any question arises as to whether Physician
         is so disabled, Physician shall, at Physician's election or at the
         request of Medical Group, submit to a medical examination by a
         physician selected by Medical Group, to whom Physician or Physician's
         guardian has no reasonable objection, to determine whether Physician is
         so disabled. If Physician (or his guardian) shall disagree with the
         determination of such physician, Physician, within thirty (30) days
         following the determination by the physician selected by Medical Group,
         may submit to a medical examination by a physician selected by
         Physician (or his guardian). If the determination of such second
         physician differs from that of the first, Medical Group and Physician
         (or his guardian), within thirty (30) days following the determination
         by such physician, shall agree upon a third physician, who shall
         examine Physician and whose determination shall be conclusive of the
         issue. If Physician does not request a second opinion, the
         determination of the first physician shall be conclusive of the issue.
         If this question arises and Physician does not submit to medical
         examination, Medical Group's determination of the issue shall be
         binding on Physician.

            (c) Termination by Medical Group for Cause.
                ---------------------------------------

                (i)  Medical Group may terminate this Agreement for cause at any
            time provided that Medical Group first gives ninety (90) days
            written notice to Physician setting forth in reasonable detail the
            nature of such cause and provides Physician with an opportunity to
            respond to the notice and discuss with the Medical Director of
            Medical Group the issues identified in the notice, and to cure the
            basis for the notice. If within that ninety (90) day period,
            Physician has not cured the problem described in the notice, then
            Medical Group may immediately terminate Physician's employment,
            without further notice provided, however, that Medical Group shall
            not be required to provide ninety (90) days notice or an opportunity
            to cure any cause that in the
<PAGE>
 
            reasonable judgment of Medical Group is not capable of being cured.
            Cause shall be determined by Medical Group in its reasonable
            judgment and shall include, but not be limited to:

                   (A)  Physician's fraud or dishonesty with respect to Medical
                   Group, its employees, patients or visitors;

                   (B)  Physician's suspension or termination from, or failure
                   to participate as an eligible provider in Medicare, Medicaid
                   or any third-party reimbursement program approved by the
                   Joint Policy Board, for cause such as quality of care,
                   utilization review, or quality assurance reasons; provided,
                   however, that termination or failure to renew Physician's
                   participation in a third-party reimbursement program due to
                   changes in the size or character of provider panels shall not
                   constitute cause under this Section 8(c)(i)(B);

                   (C)  Revocation, suspension, or failure to renew Physician's
                   Board Certifications (if any) in his primary area of
                   practice; provided, however, that such termination shall be
                   approved by Medical Advisory Board and the Joint Policy
                   Board;

                   (D)  Physician's material negligence in the performance of
                   Physician's duties or responsibilities to Medical Group;

                   (E)  Physician's breach of any material term of this
                   Agreement or any other agreement entered into in connection
                   with such Physician's affiliation with Medical Group;

                   (F)  the medical staff membership or clinical privileges of
                   Physician at any hospital in the State of Maryland or any
                   other jurisdiction: (1) being revoked or terminated, or not
                   being renewed at the election of the hospital or, without the
                   approval of the Medical Director, expiring; or (2) or being
                   reduced to a level which, in the sole judgment of the Medical
                   Director of Medical Group, would prevent Physician from
                   rendering the services contemplated by this Agreement in any
                   material respect. Medical Group may terminate this Agreement,
                   upon written notice to Physician, if Physician's medical
                   staff membership or clinical privileges at any hospital in
                   the State of Maryland or any other jurisdiction are suspended
                   other than (a) during a period of summary suspension pending
                   hearing and appeal, provided such hearing and appeal are
                   timely requested by Physician or (b) a nonrecurring,
                   temporary suspension arising solely out of failure to
                   complete medical records. During any period of summary
                   suspension of Physician's privileges (other than a
                   nonrecurring, temporary suspension arising solely out of
                   failure to complete medical records), Physician's employment
                   shall be suspended pending hearing and appeal as timely
                   requested by Physician and compensation and benefits shall be
                   continued to the extent provided by policies in effect at the
                   time;

                   (G)  Physician ceasing to be licensed to practice medicine
                   without
<PAGE>
 
                   restriction under the laws of any state in which 
                   Physician is licensed;

                   (H)  Physician ceasing to maintain a current and valid
                   Federal Drug Enforcement Agency license;

                   (I)  Physician ceasing to be covered by professional
                   liability insurance (other than as a result of Medical
                   Group's act or omission in connection with such insurance);

                   (J)  Physician being convicted of a felony or any crime
                   involving moral turpitude;

                   (K)  Physician being penalized with civil monetary fines or
                   assessment under any federal or state law involving Medicare,
                   Medicaid or any third-party reimbursement program;

                   (L)  Physician (a) engages in any conduct or is formally
                   accused of conduct for which Physician's license to practice
                   medicine reasonably would be expected to be subject to
                   revocation or suspension, whether or not actually revoked or
                   suspended, or (b) is otherwise disciplined by any licensing,
                   regulatory or professional entity or institution, the result
                   of any of which events described in clause (a) or (b) of this
                   Section 8(c)(i)(L) does, or reasonably would be expected to,
                   materially adversely affect Medical Group or significantly
                   impair the ability of Medical Group to perform medical
                   services in an amount and of a nature consistent with the
                   medical services performed at the time of such action; or

                   (M)  Medical Group or PQC is prevented by Physician or any
                   person under Physician's direction or control, from entering
                   any premises at which Medical Group provides services, and
                   such inability to enter such premises continues for more than
                   forty-eight (48) hours after written notice thereof to the
                   Joint Policy Board.

                   (ii)  Upon the termination of this Agreement pursuant to
            Section 8(c)(i) by Medical Group, subject to the provisions set
            forth below, Medical Group shall have the option to require
            Physician to:

                   (A)  Subject to cooperation from PQC and its Affiliates,
                   purchase from Medical Group, PQC or its Affiliates at Book
                   Value (as of the Purchase Closing) (1) all tangible assets of
                   Medical Group, PQC or their Affiliates that relate primarily
                   to Physician's practice or that were acquired, directly or
                   indirectly, from Physician, other than Medical Group's, PQC's
                   or its Affiliates' medical, accounting and financial records,
                   and (at a price equal to the unamortized balance of the
                   payments to Physician for intangibles (including goodwill as
                   set forth or reflected on the balance sheet of Medical Group,
                   PQC or its Affiliates) (2) a release from the restrictive
                   covenant set forth in Section 14 (the assets to be purchased
                   pursuant to (1) and (2) of this Section 8(c)(ii) referred to
                   hereinafter as the "Purchased Assets"); and
<PAGE>
 
                   (B)  Assume or pay all of Medical Group's, PQC's and its
                   Affiliates' liabilities, debts, payables and other
                   obligations (including lease and other contractual
                   obligations), or portions thereof, accrued and unpaid through
                   the Purchase Closing which relate directly or are directly
                   attributable to Physician or Physician's medical practice
                   (the "Physician Related Liabilities"). The parties agree that
                   if Physician is one (1) of a number of physicians practicing
                   within a Pod, then the parties will cooperate in good faith
                   to allocate fairly to Physician only those liabilities,
                   debts, payables and other obligations that relate directly to
                   Physician and not to other members of the Pod.

                   (iii)  The exercise of the option by Medical Group described
            in Section 8(c)(ii) shall be upon written notice thereof in the
            termination notice, if applicable, on or prior to ninety (90) days
            before the Purchase Closing. In connection with the purchase and
            sale of the Purchased Assets pursuant to this Section 8(c), Medical
            Group shall use its commercially reasonable efforts to cause such
            assets to be conveyed free of any lien, claim or encumbrance.

                   (iv)  Notwithstanding Section 8(c)(ii), this Agreement shall
            not constitute an agreement to assign any contract or asset, or any
            benefit arising thereunder or resulting therefrom, if any attempted
            assignment thereof, without the consent required or necessary for
            such assignment, would constitute a breach or violation of any
            agreement or restriction applicable to such contract or asset or in
            any way adversely affect the rights of Medical Group, Physician, or
            PQC thereunder. Medical Group agrees to use its commercially
            reasonable efforts to obtain any consent required for such
            assignment.

            (d) Termination by Physician.
                -------------------------

                      (i)  Physician may terminate this Agreement (A) upon
            written notice to Medical Group of the failure of Medical Group to
            make any payments of the compensation required under this Agreement
            when due and continued failure to pay such compensation after thirty
            (30) days notice of such failure to Medical Group unless the amount
            of such payment is being contested in good faith, (B) upon ninety
            (90) days written notice from Physician to Medical Group of Medical
            Group's failure to comply with any other material obligation of
            Medical Group under this Agreement, which failure is not cured
            within such ninety (90) day period, (C) after the first anniversary
            of the execution of this Agreement, upon not less than six (6)
            months written notice to Medical Group from Physician, and (D) upon
            written notice to Medical Group, in the event of the termination by
            Medical Group of the Services Agreement between PQC and Medical
            Group pursuant to Sections 5.2(a) [breach] or 5.2(c)(i) [breach for
            non-payment] of said Services Agreement by Medical Group or the
            termination by either party of the Services Agreement under Section
            6 [Negative Gross Margin] of Appendix B thereof.

                      (ii) Upon the termination of Physician's employment
            by Physician pursuant to Section 8(d)(i)(A), (B) or (D), Physician
            shall have the option to require Medical Group, subject to
            cooperation from PQC and its Affiliates, to
<PAGE>
 
                  sell all tangible assets of Medical Group, PQC or their
                  Affiliates that relate primarily to Physician's practice or
                  that were acquired, directly or indirectly, from Physician,
                  other than Medical Group's, PQC's or its Affiliates' medical,
                  accounting and financial records, collectively and not
                  individually, to Physician (the "Section 8(d)(ii) Assets") at
                  the lesser of (1) Book Value or (2) Fair Market Value as of
                  the date of termination. For the purposes of this Agreement,
                  "Book Value" shall have the meaning set forth in Section 10.3
                  of Appendix A of the Services Agreement, and "Fair Market
                  Value" shall mean, as to any asset, the fair market value of
                  such asset as agreed upon by Medical Group and Physician, or
                  in the event that Medical Group and Physician cannot agree to
                  such value by ninety (90) days prior to the Purchase Closing,
                  the fair market value of such assets as determined by an
                  entity (the "Independent Financial Expert") regularly engaged
                  in the business of evaluating assets of medical clinics and
                  associated businesses and that is mutually acceptable to
                  Medical Group and Physician. The Independent Financial Expert
                  may use any customary and generally accepted method of
                  determining fair market values, and shall take into account
                  the effect of any liens, claims or encumbrances (other than
                  those arising out of Physician Related Liabilities that may
                  reasonably be expected to have an effect on the value of such
                  assets. The cost of any Independent Financial Expert shall be
                  paid one-half (1/2) by Medical Group and one-half (1/2) by
                  Physician.

                      (iii)    In the event that Physician terminates this 
                  Agreement pursuant to Section 8(d)(i)(C), Physician shall have
                  the right to purchase the following assets (the "Section
                  8(d)(iii) Assets "):

                      (A)  All, but not less than all, of the physical assets
                      purchased by Medical Group from Physician as part of the
                      transaction simultaneous with which Physician became an
                      employee of Medical Group (an "Affiliation"), provided
                      that Medical Group, PQC or an Affiliate still owns such
                      physical assets. Medical Group and Physician may also
                      agree that Physician shall purchase other physician assets
                      acquired by Medical Group, PQC or an Affiliate after
                      Affiliation; provided that Medical Group shall not be
                      obligated to sell any assets acquired after Affiliation.
                      The purchase price of the physical assets shall be the
                      lesser of their Book Value or their Fair Market Value as
                      of the Purchase Closing.

                      (B)  If Physician requests, then, subject to the consent
                      of the lessor and release by the lessor of Medical Group
                      from any obligations under the lease, Medical Group agrees
                      to use commercially reasonable efforts to transfer to
                      Physician the lease relating to any premises occupied
                      solely by Physician prior to Affiliation and that
                      Physician continues to occupy at the time of termination
                      of this Agreement. In consideration of such transfer,
                      Physician shall pay Medical Group an amount equal to the
                      sum of (i) fifteen percent (15 %) of the total lease
                      obligations required to be paid during the remaining term
                      of the lease and (ii) to the extent not covered in (A)
                      above the Book Value of any leasehold improvements.
<PAGE>
 
                    (C)  Physician (notwithstanding Section 12 of this
                    Agreement) shall be entitled for a three (3) month period
                    commencing upon the delivery of Physician's termination
                    notice to solicit any employee of Medical Group directly
                    providing support for Physician's medical practice to leave
                    such employee's employment with Medical Group. Prior to
                    soliciting such employee, Physician shall notify Medical
                    Group of Physician's intent to solicit such employee and pay
                    Medical Group an amount equal to three (3) months salary and
                    benefits of any employee so solicited.

                    (D)  Medical Group shall not attempt to prevent Physician
                    from obtaining and using the telephone number that Physician
                    used prior to Affiliation if such telephone number has been
                    used by a Pod in which Physician is the sole physician
                    employee. Medical Group shall have no obligation to cause
                    such telephone number to be assigned to Physician and
                    Physician shall be responsible for all costs associated with
                    reestablishing such phone number.

                    (E)  Medical Group shall retain custody of patient records.
                    Physician shall be entitled, at Physician's cost and at the
                    written request or with the written approval of the patient,
                    to make copies of the patient record for any patient to whom
                    Physician provided services. If requested by a patient,
                    Medical Group shall transfer copies of each patient's
                    medical records as directed by the patient.

                    (F)  Medical Group will not interfere with Physician's
                    efforts to reactivate any provider numbers under any managed
                    care contracts that were assigned to Physician prior to the
                    date of his initial employment hereunder. Medical Group
                    shall not be obligated to terminate or transfer any provider
                    number that it possesses and shall not be liable to
                    Physician if Physician is unable to establish or re-
                    establish provider status under any managed care contract.

                    (G)  Except as provided in clause (C) of this Section
                    8(d)(iii), Physician shall continue to be subject to the
                    restrictive covenants and agreements in Sections 11, 12 and
                    14 of this Agreement.

                    (iv)  The exercise of the option by Physician described in
            Sections 8(d)(ii) and (iii) shall be upon written notice thereof in
            the termination notice, if applicable, on or prior to ninety (90)
            days before the Purchase Closing. In connection with the purchase
            and sale of the Section 8(d)(ii) Assets or the Section 8(d)(iii)
            Assets as appropriate, pursuant to Sections 8(d)(ii) or 8(d)(iii) as
            appropriate, Medical Group shall use its commercially reasonable
            efforts to cause such assets to be conveyed free of any lien, claim
            or encumbrance.

                     (v)  Notwithstanding Sections 8(d)(ii) and (iii), this
            Agreement shall not constitute an agreement to assign any contract
            or asset, or any benefit arising thereunder or resulting therefrom,
            if any attempted assignment thereof, without the consent required or
            necessary for such assignment, would constitute a breach or
            violation of any agreement or restriction applicable to
<PAGE>
 
            such contract or asset or m any way adversely affect the rights of
            Medical Group or Physician or PQC thereunder. Medical Group agrees
            to use its commercially reasonable efforts to obtain any consent
            required for such assignment.

            (e)  Mutual Termination.
                 -------------------

                 (i)  Either Physician or Medical Group may terminate this
            Agreement if (i) a law firm with a nationally recognized expertise
            in health care law and acceptable to Medical Group and the Joint
            Policy Board renders an opinion to Medical Group with a copy to the
            Joint Policy Board and Physician stating that a material provision
            of this Agreement is in violation of applicable law; or (ii) any
            court or regulatory agency enters an order finding a material
            provision of this Agreement is in violation of any applicable law
            and in either case (i) or (ii), the parties are unable, after a
            period of good faith negotiation not to exceed thirty (30) days
            after notice to either party to agree upon such amendments to this
            Agreement as are necessary to cause this Agreement to comply with
            applicable law and which preserve the underlying economic and
            financial arrangements between the parties without substantial
            economic detriment to either party.

                 (ii)  In the event of termination under this Section 8(e),
            Medical Group shall have the option to require Physician to
            purchase, and Physician shall have the option to require Medical
            Group to:

                 (A)  Subject to cooperation from PQC and its Affiliates,
                 purchase from Medical Group, PQC or its Affiliates at Book
                 Value, all tangible assets of Medical Group, PQC or their
                 Affiliates that relate primarily to Physician's practice or
                 that were acquired, directly or indirectly, from Physician,
                 other than Medical Group's, PQC's or its Affiliates' medical,
                 accounting and financial records (the "Section 8(e)(ii)
                 Assets"); and

                 (B)  Assume or pay all of the Physician Related Liabilities as
                 defined in Section 8(c)(ii)(B). The parties agree that if
                 Physician is one (I) of a number of physicians practicing
                 within a Pod, then the parties will cooperate m good faith to
                 allocate fairly to Physician only those liabilities, debts,
                 payables and other obligations that relate directly to
                 Physician and not to other members of the Pod.

                 (iii)  The exercise of the option by a party described in
            Section 8(e)(ii) shall be upon written notice thereof in the
            termination notice, if applicable, on or prior to ninety (90) days
            before the Purchase Closing. In connection with the purchase and
            sale of the Section 8(e)(ii) Assets pursuant to this Section 8(e),
            Medical Group shall use its commercially reasonable efforts to cause
            such assets to be conveyed free of any lien, claim or encumbrance.

                 (iv)   Notwithstanding Section 8(e)(ii), this Agreement shall
            not constitute an agreement to assign any contract or asset, or any
            benefit arising thereunder or resulting therefrom, if any attempted
            assignment thereof, without the consent required or necessary for
            such assignment, would
<PAGE>
 
                  constitute a breach or violation of any agreement or
                  restriction applicable to such contract or asset or in any way
                  adversely affect the rights of Medical Group or Physician
                  thereunder. Medical Group agrees to use its commercially
                  reasonable efforts to obtain any consent required for such
                  assignment.

                  (f) Effect of Termination on Accrued Salary and Benefits. In
                      -----------------------------------------------------
         the event that this Agreement is terminated, Medical Group shall pay to
         Physician the compensation and benefits otherwise payable to Physician
         under this Agreement through the last day of his actual employment by
         Medical Group.

                  If, but only if, this Agreement is terminated under Section
         8(a) [death], 8(b) [disability], 8(d) [termination by Physician] or
         8(e) [mutual termination], then in addition to amounts owed to
         Physician under the preceding sentence, Medical Group shall pay
         (without duplication of any amounts owed hereunder) such portion (if
         any) of the available Distribution Pool (if any) accrued on the
         financial statements of Medical Group prior to the date of termination
         as may be approved by the Compensation Committee in its sole discretion
         (the "Discretionary Amount"). No Discretionary Amount shall be payable
         in the event of termination under any other section of this Agreement,
         including without limitation Section 8(c).

                  (g) Terms of Purchase. The closing of the transactions
                      -----------------
         contemplated by Sections 8(c)(ii), 8(d)(ii), 8(d)(iii) or 8(e)(ii) (the
         "Purchase Closing") shall occur on a date mutually acceptable to
         Medical Group and Physician that shall be within one hundred and eighty
         (180) days after receipt of a termination notice (or such later date as
         is necessary for Medical Group to obtain lessor consents to the
         assignment to Physician of leases of real and personal property to be
         assumed by Physician). Subject to the conditions set forth below, at
         the Purchase Closing, Medical Group shall transfer and assign, or shall
         use its reasonable efforts to cause PQC or its Affiliates to transfer
         and convey, the Purchase Assets, the Section 8(d)(ii) Assets, the
         Section 8(d)(iii) Assets, or the Section 8(e)(ii) Assets, as the case
         may be, to Physician and in consideration therefor, Physician shall (a)
         pay to Medical Group the purchase price in cash and (b) assume, if
         applicable, Physician Related Liabilities. Each of Medical Group and
         Physician shall execute such documents or instruments as are reasonably
         necessary, in the opinion of Medical Group, Physician and their
         respective counsel, to effect the foregoing transaction.

                  (h) Exception to Purchase. Notwithstanding anything contained
                      ---------------------
         herein to the contrary, Medical Group shall not be obligated to sell
         the Purchase Assets, the Section 8(d)(ii) Assets, the Section 8(d)(iii)
         Assets, or the Section 8(e)(ii) Assets, as the case may be, to
         Physician if Physician is not able to pay the purchase price therefor
         pursuant to the terms set forth above at the Purchase Closing. In such
         event, Physician shall surrender the assets in Physician's possession
         or control to Medical Group as of the Purchase Closing. If Physician
         fails to so surrender the assets, Medical Group may, without prejudice
         to any other remedy which it may have hereunder or otherwise, enter the
         premises and take possession of the assets and expel or remove
         Physician and any other person who may be occupying the Premises or any
         part thereof, by force if necessary, without being liable for
         prosecution or any claim for damages therefor.

                  (i) Waiver of Restrictive Covenants. If Physician's employment
                      --------------------------------
         terminates
<PAGE>
 
         pursuant to Sections 8(b) (if but only if Physician, upon any recovery
         from disability during the original term hereof sufficient to permit
         him to return to medical practice, has first offered Medical Group the
         option to rehire him on the terms set forth herein), 8(d)(i)(A),
         8(d)(i)(B), 8(d)(i)(D), or 8(e), Physician's obligation to comply with
         the restrictions and obligations contained in Sections 11, 12 and 14
         hereof shall be waived, and those sections shall be of no force and
         effect.

         9.  Withholding.  All payments made by Medical Group under this 
             -----------
Agreement shall be reduced by any tax or other amounts required to be withheld 
by Medical Group under applicable law.

         10. Records.  Physician and Medical Group agree that, as between 
             -------
Medical Group and Physician, all patient records and other records are the 
property of Medical Group and not the property of Physician.

         11. Nonsolicitation of Patients. Physician agrees that, during the term
             ---------------------------
of this Agreement and for two (2) years thereafter, Physician will not solicit
any patients of Medical Group for whom Physician provides any services during
the term of this Agreement, nor suggest, request or direct that any such
patients change their health plan from one in which Medical Group participates
or plans to participate to a health plan in which Physician, directly or
indirectly, participates or plans to participate, nor, unless the patient asks
to use the services of Physician, suggest, request or direct that any such
patients request that their medical records be copied or otherwise removed or
transferred from Medical Group's office, nor remove or copy any medical records
or patient mailing lists. Medical Group acknowledges that neither advertising in
a "yellow pages" telephone directory nor inclusion of Physician's name in the
directory or similar advertising of a general nature of a medical plan shall be
deemed to be the solicitation of patients.

         12. Nonsolicitation of Employees. Physician agrees that, during the
             ----------------------------
term of this Agreement and for two (2) years thereafter, Physician will not
solicit, directly or indirectly, any physician, nurse or other medical or
administrative employee, any agent or any independent contractor of Medical
Group or induce or seek to induce, or take action which results in the
termination of employment or other arrangements between Medical Group and such
employee, agent or independent contractor or otherwise diminishes or interferes
with such employment or contractual arrangements.

         13. Referrals of Patients of Medical Group. Physician agrees that,
             --------------------------------------
during the term of this Agreement and for two (2) years thereafter, Physician
will give to all patients of Medical Group, or persons who contact Physician as
a result of Physician's association with Medical Group, who are seeking medical
services within the Practice Area (as defined in Section 14 below) the phone
number and address of Medical Group and any Medical Group physicians identified
by the patient and known to Physician.

         14. Noncompetition. Physician agrees that, during the term hereof and
             --------------
for a period of one (1) year after the termination of this Agreement, such
Physician shall not establish, operate or provide physician or other medical
services (whether as an employee, shareholder, partner, independent contractor,
manager, consultant or otherwise) at any medical office, clinic or other health
care facility providing services similar to those provided by Medical Group, PQC
or its Affiliates within fifteen (15) miles of the premises at which Physician
practiced at the time of such termination of employment as set forth in Appendix
<PAGE>
 
C (the "Practice Area"); provided, however, that Physician shall not be
prohibited from (i) working at a research or teaching facility if Physician does
not devote more than ten percent (10%) of Physician's time to clinical practice
or (ii) practicing medicine in the Practice Area either as a solo practitioner
or with one (1) other physician or (iii) admitting a patient to a hospital in
the Practice Area where such admission is in the best medical interest of the
patient. In addition, during the term of this Agreement, Physician shall not
directly or directly (whether as a shareholder, employee, individual, partner,
independent contractor, consultant or otherwise) establish, operate or provide
any Integrated Health Services or any medical practice management services
provided by Medical Group, PQC or its Affiliates in the Practice Area. Physician
agrees that, during the term hereof and for a period of two (2) years after the
termination of this Agreement, except as otherwise expressly permitted by this
Agreement, Physician shall not directly or indirectly (whether as a shareholder,
employee, individual, partner, independent contractor, consultant or otherwise)
establish, operate or provide any Integrated Health Services or any other
medical practice management services provided by Medical Group, PQC or its
Affiliates in the Practice Area. For purposes of this Agreement, "Integrated
Health Services" shall mean any business that Medical Group or PQC establishes
after the date of execution of the Services Agreement, whether directly or
through a subsidiary, which provides medical related services that are not
traditionally performed by physicians or physician practices at medical offices
(it being understood that in-office laboratory services are not Integrated
Health Services).

         15. Enforcement of Covenants. Physician acknowledges that he has
             ------------------------
carefully read and considered all the terms and conditions of this Agreement,
including the restraints imposed upon Physician pursuant to Sections 11, 12, 13,
14 and 16 hereof. Physician agrees that said restraints are necessary for the
reasonable and proper protection of Medical Group and its goodwill, confidential
information and relationships, and economic advantage and agrees that each and
every one of the restraints is reasonable in respect to subject matter, length
of time and geographic area. Physician further acknowledges that, were he to
breach any of the covenants contained in Sections 11, 12, 13, 14 or 16 hereof,
Medical Group would be harmed and the damage to Medical Group would be
irreparable. Accordingly, if Physician breaches any obligation of Sections 11,
12, 13, 14 or 16, in addition to any other remedies available under this
Agreement, at law or in equity, Medical Group shall be entitled to enforce this
Agreement by preliminary and permanent injunctive relief and by specific
performance of the Agreement. Additionally, nothing in this Section 15 shall
limit Medical Group's right to recover any other damages to which it is entitled
as result of Physician's breach.

         16. Confidentiality. Physician will not, directly or indirectly, use or
             ---------------
disclose any professional or trade secrets or confidential information with
respect to Medical Group, its medical practice or its patients except as
required by law or legal process. In addition to the restrictions set forth
above, Physician agrees to comply with and be bound by any restrictions on the
use or disclosure of Intellectual Property of PQC set forth in the Services
Agreement, a copy of which has been given to Physician. Physician shall not copy
any documents, tapes or other media containing Intellectual Property
("Documents") or remove any Documents or copies from Medical Group premises.
Physician will return to Medical Group immediately after Physician's employment
terminates, and at such other times as may be specified by Medical Group, all
Documents and copies and all other property of Medical Group then in Physician's
possession or control. "Intellectual Property" means all (i) patents, patent
applications, patent disclosures and all related continuation,
continuation-in-part, divisional, reissue, re-examination, utility model,
certificate of invention and design patents, registrations
<PAGE>
 
and applications for registrations, (ii) trademarks, services marks, trade
dress, logos, trade names and corporate names and registration and applications
for registration thereof, (iii) copyrights and registrations and applications
for registration thereof, (iv) mask works and registrations and applications for
registration thereof, (v) computer software, data and documentation, (vi) trade
secrets and confidential business information, whether patentable or
non-patentable and whether or not reduced to practice, know-how, clinical
product and service processes and techniques, research and development
information, medical protocols, copyrightable works, financial, marketing and
business data, pricing and cost information, business and marketing plans and
customer and supplier lists and information, (vii) other proprietary rights
relating to the foregoing (including, without limitation, remedies against
infringement thereof and rights of protection of interest therein under the laws
of all jurisdictions) and (viii) copies and tangible embodiments thereof.
Intellectual Property shall also include such information that Medical Group may
receive or has received belonging to patients, PQC or others who do business
with Medical Group. Intellectual Property does not include any information that
Physician can establish (a) is or becomes generally available to and known by
the public or in the trade (other than as a result of an unpermitted disclosure
directly or indirectly by Physician or another person who was not authorized by
Medical Group to make such disclosure); or (b) is or becomes available to
Physician on a nonconfidential basis from a source other than Medical Group, PQC
or its Affiliates, advisers, or representatives, provided that such source is
not and was not bound by a confidentiality agreement with or other obligation of
secrecy to Medical Group of which Physician has knowledge. Notwithstanding
anything to the contrary in this Section 16, the obligations of Physician not to
use or disclose Intellectual Property set forth in this Section 16 shall be in
effect during the entire duration of Physicians employment with Medical Group
and for three (3) years thereafter, except that Physician's obligations with
respect to any Intellectual Property that constitutes a "trade secret" under
applicable law shall be in effect during the entire duration of Physician's
employment with Medical Group and for as long thereafter as such information
continues to constitute a trade secret.

         17. Miscellaneous.
             -------------

             17.1. Arbitration. Any controversy or claim between Medical
                   -----------
Group, PQC and Physician arising under or relating to this Agreement or any
breach thereof (including the question of whether any particular matter is
arbitrable hereunder) shall be settled by arbitration in accordance with the
commercial arbitration rules of the American Arbitration Association then in
effect; provided, however, that no provision of this Agreement shall be
modified, deleted or added by reason of such arbitration. Medical Group and
Physician agree to abide by all awards rendered in such arbitration proceedings,
and all such awards may be filed by the prevailing party in any federal or state
court having proper jurisdiction, as a basis for judgment in the issuance of
execution thereon. Such arbitration shall be initiated by either Medical Group
or Physician by serving a written demand on the other party and the Joint Policy
Board stating the substance of the controversy and the contention of the party
requesting arbitration. The American Arbitration Association shall appoint or
provide the procedure for the determination of a single neutral arbitrator who
shall be a fit and impartial person. The fees and costs of the arbitrator and
related expenses of arbitration shall be borne by the non- prevailing party. If
the arbitrator determines that neither party has substantially prevailed, the
parties shall bear equally the fees and costs of the arbitrator and the related
expenses of arbitration.

             17.2. Contract Modifications for Prospective Legal Events.
                   ---------------------------------------------------
In the event any
<PAGE>
 
state or federal laws or regulations, now existing or enacted or promulgated
after the date of execution of this Agreement are interpreted by judicial
decision, a regulatory agency or legal counsel in such a manner as to indicate
that this Agreement or any provision hereof may be in violation of such laws or
regulations, Medical Group shall propose to the Joint Policy Board for its
approval such amendments to this Agreement as necessary to comply with
applicable law and preserve the underlying economic and financial arrangements
between Physician and Medical Group without substantial economic detriment to
either Medical Group or Physician. Any such amendment approved by the Joint
Policy Board shall be binding upon Physician, and Physician hereby consents to
any such amendment. To the fullest extent permitted by law, each of Physician
and Medical Group waives and agrees not to 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
17.2.

             17.3. No Waive, Remedies Cumulative. None of Medical Group,
                   -----------------------------
PQC or Physician shall by any act, delay, indulgence, omission or otherwise be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
default in or breach of any of the terms and conditions hereof. No failure to
exercise, nor any delay in exercising, on the part of either Medical Group, PQC
or Physician, any right, power or privilege hereunder shall operate as a waiver
thereof. No single or partial exercise of any right, power or privilege shall
operate as a waiver thereof. No single or partial exercise of any right, power
or privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. No remedy set forth in this
Agreement or otherwise conferred upon or reserved to either Medical Group or
Physician shall be considered exclusive of any other remedy available to either
Medical Group or Physician, but the same shall be distinct, separate and
cumulative and may be exercised from time to time as often as occasion may arise
or as may be deemed expedient.

             17.4. Availability of Certain Documents. The parties agree, to
                   ---------------------------------
the extent required by law necessary to permit receipt of reimbursement for
services by Medical Group, to make available to the Secretary of Health and
Human Services, the Comptroller General of 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.

             17.5. Severability. If any provision in this Agreement,
                   ------------
including without limitation any of the covenants set forth in Sections 3.3, 8,
11, 12, 13, 14, 15 or 16, is held by a court of competent jurisdiction to be
invalid or unenforceable for any reason, the parties desire, intend and agree
that it shall not affect any other provision and shall be construed by limiting
it so as to be enforceable to the maximum extent permissible by law.

             17.6. Assignment. This Agreement shall be binding upon and
                   ----------
shall inure to the benefit of Medical Group and any successor of Medical Group
by reorganization, merger, consolidation, acquisition, transfer of Medical Group
stock or liquidation and any assignee of all or substantially all of the
business or assets of Medical Group. Medical Group may assign this Agreement to
any of such persons without the consent of Physician. This Agreement shall be
binding upon and shall inure to the benefit of Physician and Physician's
personal and legal representatives. Medical Group requires the personal services
of Physician hereunder, and Physician may not assign this Agreement or delegate
any duties hereunder.
<PAGE>
 
             17.7. Notices. Any notices, requests, demands and other
                   -------
communications provided for by this Agreement shall be in writing and shall be
effective when delivered in person or deposited in the United States mail,
postage prepaid, registered or certified, and addressed to Physician at
Physician's last known address on the books of Medical Group or, in the case of

             17.8. Acknowledgment of Services Agreement. Physician
                   ------------------------------------
understands that, as a physician employed by Medical Group, he will be a member
of a Pod and that certain matters affecting the governance and operation of the
Pod are described in the Services Agreement. Physician acknowledges that certain
terms of the Services Agreement are applicable to him as a Pod Physician,
including but not limited to reasonably cooperating with Medical Group in
credentialing, utilization review, payor contracting and other activities
described in the Services Agreement. Pursuant to the Services Agreement,
Physician agrees that the provisions of the Services Agreement may be enforced
only upon written direction of a majority of the Physician Members of Medical
Group.

             17.9. No Obligation to Third Parties. Except as expressly set
                   ------------------------------
forth in this Section, none of the obligations and duties of Physician or
Medical Group under this Agreement shall in any way or in any manner be deemed
to create any obligation of Physician or Medical Group to, or any rights in, any
person or entity not a party to this Agreement. Notwithstanding the foregoing,
in accordance with and subject to the terms of the provisions of the Service
Agreement between Medical Group and PQC, PQC is hereby made a third party
beneficiary of and may enforce the obligations of Medical Group hereunder by any
means, at law or in equity.

             17.10. Gender.  References herein to the masculine shall be
                    ------
deemed to refer to the feminine or neuter gender as the context may require.

                              COMPENSATION FORMULA
                              ____________________


         Reference is made to Appendices A and B to the Services Agreement, the
definitions and provisions of which are incorporated herein by reference.

         1. Compensation Pool. As exclusive compensation for the services of
            -----------------
Medical Group Physician under this Agreement and all other Medical Group
Physician employees of Medical Group under their respective Employment
Agreements, Medical Group shall establish a compensation pool (the "Compensation
Pool") which, on an annual basis, shall be equal to all amounts distributed to
Medical Group pursuant to Section 2 of Article A of Appendix B of the Services
Agreement. The Compensation Pool shall be allocated among and distributed to
Medical Group Physician and other Medical Group Physician employees of Medical
Group as provided in this Appendix A. Medical Group Physician shall not be
entitled to any compensation for services under this Agreement except as
provided in this Appendix A.

         2. Establishment of Budgets for Medical Group Physician Pods. Prior to
            ---------------------------------------------------------
the beginning of each Fiscal Period, a capital and operating budget for each
Medical Group Physician Pod shall be established pursuant to Section 3.8 of the
Services Agreement. At any point during a Fiscal Period, the Joint Policy Board
may, and if the actual Medical Group Physician Pod Practice Revenues less actual
Medical Group Physician Pod Practice Expenses is below budgeted levels for such
Medical Group Physician Pod or if there is a projected negative Net Margin,
shall, review the budgets for such Medical Group Physician Pod and make such
changes to such budgets, including the aggregate Pod Distributions (as defined
in Section 3 below), as the Joint Policy Board deems to be appropriate. All
capital and operating budgets, and changes thereto, also shall be subject to the
approval of PQC.

         3. Allocation of the Compensation Pool among Medical Group Physicians.
            ------------------------------------------------------------------
(a) On a biweekly basis, Medical Group shall distribute to each Medical Group
Physician Pod from the Compensation Pool an amount equal to one twenty-sixth of
the aggregate Medical Group Physician Draw allocated to such Medical Group
Physician Pod pursuant to the operating budget approved by the Joint Policy
Board (the "Pod Distribution") less the Deductible Expenses allocated to such
Medical Group Physician Pod (which amount shall be distributed to Medical Group
to pay such Deductible Expenses); provided, however, if at any time during a
Fiscal Period: (1) Medical Group determines that the amount allocated to the
Compensation Pool for any Fiscal Period pursuant to Section 1 of this Appendix A
may be less than ninety-five percent (95 %) of the aggregate Medical Group
Physician Draw budgeted for such Fiscal Period, or (2) Medical Group or the
Joint Policy Board determine that: (a) the Medical Group Physician Pod's
Practice Expenses for such Fiscal Period will exceed the budgeted Medical Group
Physician Pod Practice Expenses for such Medical Group Physician Pod, or (b) the
Medical Group Physician Pod's Practice Revenues will be less than the Medical
Group Physician Pod's budgeted Practice Revenues, Medical Group may reduce the
Pod Distributions in such manner as Medical Group determines to be appropriate
in order that the aggregate Pod Distributions to all Medical Group Physician
Pods do not
<PAGE>
 
exceed the amount of the Compensation Pool for such Fiscal Period. The Pod
Distribution shall be allocated among the Medical Group Pod Physicians as
determined by the majority of the Medical Group Pod Physicians.

         4. Allocation of Variable Distribution Pool. There shall be a
            ----------------------------------------
Compensation Committee (the "Compensation Committee") consisting of at least
seven (7) Medical Group Physicians elected annually by the Physician Members of
Medical Group, a minimum of three (3) of whom shall be primary care physicians,
two (2) of whom shall be pediatricians and two (2) of whom shall be specialists.
Any action of the Compensation Committee shall require the affirmative vote of
at least one (1) primary care physician, one (1) pediatrician, and one (1)
specialist. Within forty-five (45) days of the end of each three (3) month
period, Medical Group shall advise the Compensation Committee of the amount, if
any, of Variable Distribution. The Compensation Committee, by the approval of a
majority of the members of such committee, shall determine how the Variable
Distribution, if any, shall be allocated among the Medical Group Physician Pods.
The Variable Distribution, if any, to a Medical Group Physician Pod shall be
allocated among the Medical Group Pod Physicians as determined by a majority of
the Medical Group Pod Physicians.

         5. Determination of Compensation Committee I Majority of Medical Group
            -------------------------------------------------------------------
Pod Physicians Final. The determination of the Compensation Committee (with
- --------------------
respect to allocating the Variable Distribution, if any, among Medical Group
Physician Pods) and the majority of Medical Group Pod Physicians (with respect
to allocating the Pod Distribution and any Variable Distribution granted to such
Medical Group Physician Pod among the Medical Group Pod Physicians) pursuant to
this Appendix A shall be binding upon Medical Group and Medical Group Physician,
and neither PQC nor Medical Group shall have any liability to Medical Group
Physician as a result of any determination of the Compensation Committee or
majority of Medical Group Pod Physicians; provided, however, that Medical Group
shall not be required to make any distribution in accordance with the
determinations of the Compensation Committee or majority of Medical Group Pod
Physicians that Medical Group reasonably believes to conflict with any federal
or state statute or regulation. In no event shall any Medical Group Physician be
entitled to any compensation in addition to that determined pursuant to this
Appendix A nor shall the aggregate compensation to all Medical Group Physicians
with respect to any Fiscal Period exceed the amount of the Compensation Pool for
such Fiscal Period.

         6. Initial Individual Draw. The portion of the aggregate Medical Group
            -----------------------
Physician Draw allocable to the Physician is (Draw) on an annualized basis
(payable on a bi-weekly basis as set forth in this Appendix A), for the one
month period ending December 31, 1996, and the Fiscal Period ending December 31,
1997, subject to adjustment from time to time as provided in the Services
Agreement; which number expressly includes Nine Thousand Six Hundred Eighty
Dollars ($9,680) (being an amount equal to the standard benefit package approved
by the Joint Policy Board); provided that at the direction of the Physician,
some or all of such $9,680 may be applied either to the payment of benefit
premiums (in which case such amount shall be treated as a Practice Expense) or
shall be paid to the Physician as Physician Draw.

         7. Threshold for Discretionary Expenses.  Expenditures by the 
            ------------------------------------
Physician's Medical Group Physician Pod in any Fiscal Period in excess of the

     15.9  Indemnification.
           --------------- 

               (a) PQC shall ensure that the directors and officers liability
insurance purchased by Flagship or PQC on behalf of Shareholder shall include
coverage for any claims against Shareholder or liabilities arising out of
Shareholder's performance of the Shareholder's obligations under this Agreement
or the Shareholder's involvement, in the Shareholder's capacity as a shareholder
of Flagship (but not in the Shareholder's capacity as a physician), in a
proceeding involving alleged medical malpractice by a physician employee of
Flagship, and PQC shall indemnify Shareholder for any costs and expenses arising
out of such a proceeding in the event such costs and expenses are not reimbursed
pursuant to such policy.

               (b) Notification and Defense of Claim.  Not later than thirty 
                   ---------------------------------      
(30) days after receipt by Shareholder of notice of the commencement of any
action, suit or proceeding, Shareholder will, if a claim in respect thereof is
to be made against PQC under this Agreement, notify PQC of the commencement
thereof but the omission so to notify PQC will not relieve PQC from any
liability which it may have to Shareholder otherwise than under this Agreement.
With respect to any such action, suit, or proceeding as to which Shareholder
notifies PQC of the commencement thereof:

                    (i)  PQC will be entitled to participate therein at its own
expense;

                    (ii) Except as otherwise provided below, to the extent that
it may wish, PQC jointly with any other indemnifying party similarly notified
will be entitled to assume the defense thereof, with counsel reasonably
satisfactory to Shareholder. After notice from PQC to Shareholder of its
election so as to assume the defense thereof, PQC will not be liable to
Shareholder under this Agreement for any legal or other expenses subsequently
incurred by Shareholder in connection with the defense thereof other than
reasonable costs of investigation or as otherwise provided below. Shareholder
shall have the right to employ separate Shareholder's counsel in such action,
suit, or proceeding but the fees and expenses of such counsel incurred after
notice from PQC of its assumption of the defense thereof shall be at the expense
of Shareholder unless (A) the employment of counsel by Shareholder has been
authorized by PQC, (B) Shareholder or Shareholder's counsel, in a written
opinion to PQC, shall have reasonably concluded that there may be a conflict of
interest between PQC and Shareholder in the conduct of the defense of such
action or (C) PQC shall not in fact have reasonably promptly employed counsel to
assume the defense of such action, in each of which cases the fees and expenses
of Shareholder's separate counsel shall be at the expense of PQC. PQC shall not
be entitled to assume the defense of any action, suit, or proceeding brought by
or on behalf of PQC or as to which Shareholder shall have made the conclusion
provided for in (B) above; and

                                      -7-
<PAGE>
 
                    (iii) PQC shall not be liable to indemnify Shareholder under
this Agreement for any amounts paid in settlement of any action or claim
effected without its written consent. PQC shall be permitted to settle any
action except that it shall not settle any action or claim in any manner which
would impose any penalty or limitation on Shareholder without Shareholder's
written consent. Neither PQC nor Shareholder will unreasonably withhold its
consent to any proposed settlement.

                (b)    The Stockholder agrees to enter into, and the shares of
Common Stock shall be subject to, the Stockholder's Agreement, dated as of

as follows:

                       (i)    The Stockholder is acquiring the Common Stock for
the Stockholder's own account for investment only, and not with a view to, or
for sale in connection with, any distribution of the shares of Common Stock in
violation of the Securities Act of 1933 (the "Securities Act"), or any rule or
regulation under the Securities Act.

                       (ii)   The Stockholder has received a copy of the 
Confidential Private Placement Memorandum, dated December 10, 1996, as
Supplement on December 12, 1996, with respect to PQC and the Common Stock and
has had such opportunity as the Stockholder has deemed adequate to obtain from
representatives of PQC such information as is necessary to permit the
Stockholder to evaluate the merits and risks of the Stockholder's investment in
PQC.

                       (iii)  The Stockholder has sufficient experience in 
business, financial and investment matters to be able to evaluate the risks
involved in the acquisition of the shares of Common Stock and to make an
informed investment decision with respect to such acquisition.

                       (iv)   The Stockholder can afford a complete loss of 
the value of the shares of Common Stock and is able to bear the economic risk of
holding such Common Stock for an indefinite period.

                       (v)    The Stockholder understands that (i) the shares 
of Common Stock have not been registered under the Securities Act and are
"restricted securities" within the meaning of Rule 144 under the Securities Act,
(ii) the Common Stock cannot be sold, transferred or otherwise disposed of
unless they are subsequently registered under the Securities Act or an exemption
from registration is then available; (iii) in any event, the exemption from
registration under Rule 144 will not be available for at least two (2) years and
even then will not be available unless a public market then exists for the
capital stock of PQC, adequate information concerning PQC is then available to
the public, and other terms

                                        3
<PAGE>
 
and conditions of Rule 144 are complied with; and (iv) there is now no
registration statement on file with the Securities and Exchange Commission with
respect to any stock of PQC and PQC has no obligation or current intention to
register the Common Stock under the Securities Act.

                       (vi)   A legend substantially in the following form 
will be placed on the certificate representing the Common Stock:

             "The shares represented by this certificate have not been
             registered under the Securities Act of 1933, as amended, and may
             not be sold, transferred or otherwise disposed of in the absence of
             an effective registration statement under such Act or an opinion of
             counsel satisfactory to the corporation to the effect that such
             registration is not required."

                       (vii)  The Stockholder is an "accredited investor" 
as defined in Rule 501 of the rules and regulations under the Securities Act.

         1.13   Certain Tax Agreements.  The parties intend to adopt this
                ----------------------
Agreement and Merger as a tax-free reorganization under Section 368(a) of the
Internal Revenue Code of 1986, as amended, (the "Code"). The parties shall not
take a position on any tax return or engage in any activities inconsistent with
this Section 1.13. Without limiting the foregoing the Stockholder agrees that:

                (a)     The Stockholder has not sold, exchanged, transferred or
disposed of or received any shares of the Company's capital stock in
contemplation of the Merger, and the Stockholder has no present intent to sell,
exchange, transfer, dispose of or receive the Company's capital stock in
contemplation of the Merger, nor has the Stockholder entered into any
discussions or negotiations with regard to the possible sale, exchange, transfer
or other disposition of such shares.

                (b)      The Stockholder is not subject to any obligation to
sell, exchange, transfer or otherwise dispose of all or any of the shares of PQC
to be received by the Stockholder in the Merger. The Stockholder has not entered
into any discussions or negotiations with regard to the possible sale, exchange,
transfer or other disposition of all or any of such shares. The Stockholder has
no plan or intent to engage in any transaction or arrangement that would reduce
the Stockholder's risk of ownership in any way, including without limitation a
short sale, hedging transaction or otherwise, with respect to all or any of such
shares.

                (c)      Until December 31, 1998, the Stockholder shall not,

covenant or agreements to be performed by, the Company or the Stockholder, in
each case contained in this Agreement or the Stockholders Agreement;

                      (ii)  failure of the Stockholder to have good, valid and

assert, or based upon: (A) ownership or rights to ownership of any shares of

from, and against all Damages imposed on or incurred by such Company Indemnified
Persons which relate to or arise out of any breach of any representation or
warranty of, or covenant to be performed by, PQC or MCP, in each case contained

         7.2 Method of Asserting Claims.
             ---------------------------
                  (a) An Indemnified Party shall give prompt written notice to
an indemnifying party (the "Indemnifying Party") of any payments, demands,
claims, suits, judgments, liabilities, losses, costs, damages or expenses (a
"Claim") in respect of which such Indemnifying Party has a duty to provide
indemnity to such Indemnified Party under this Article VII, except that any
delay or failure so to notify the Indemnifying Party only shall relieve the
Indemnifying Party of its obligations hereunder to the extent, if at all, that
it is prejudiced by reason of such delay or failure.

                  (b) If a Claim is brought or asserted by a third party (a
"Third-Party Claim"), the Indemnifying Party shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to the Indemnified
Party and the payment of all expenses. The Indemnified Party shall have the
right to employ separate counsel in such Third-Party Claim and participate in
the defense thereof, but the fees and expenses of such counsel shall be at the
expense of the Indemnified Party. In the event that the Indemnifying Party,
within twenty (20) days after written notice of any Third-Party Claim, fails to
assume the defense thereof, or in the event the Indemnifying Party fails to
demonstrate, to the reasonable satisfaction of the Indemnified Party, that it
has sufficient assets to meet its indemnification obligations hereunder, the
Indemnified Party shall have the right to undertake the defense, compromise or
settlement of such Third-Party Claim for the account of the Indemnifying Party.
Anything in this Section 7.2(b) to the contrary notwithstanding, the
Indemnifying Party shall not, without the Indemnified Party's prior written
consent, settle or compromise any Third-Party Claim or consent to the entry of
any judgment with respect to any ThirdParty Claim which would have any adverse
effect on the Indemnified Party, except as provided immediately below. The
Indemnifying Party may, without the Indemnified Party's prior written consent,
settle or compromise any such Third-Party Claim or consent to entry of any
judgment with respect to any Third-Party Claim which requires solely money
damages paid by the Indemnifying Party and which includes as an unconditional
term thereof the release by the claimant or the plaintiff of the Indemnified
Party from all liability in respect of such Third-Party Claim.

                  (c) With respect to any Claim other than a Third Party Claim,
the Indemnifying Party shall have thirty (30) days from receipt of written
notice from the Indemnified Party of such Claim within which to respond thereto.
If the Indemnifying Party does not respond within such thirty (30) day period,
the Indemnifying Party shall be deemed to have accepted responsibility to make
payment and shall have no further right to contest the validity of such Claim.
If the Indemnifying Party notifies the Indemnified Party within such thirty (30)
day period that it rejects such Claim in whole or in part, the Indemnified

                                       25
<PAGE>
 
Party shall be free to pursue such remedies as may be available to the
Indemnified Party under applicable law.

         7.3 Survival. All representations and warranties made by the Parties
             ---------
herein or in any instrument or document furnished in connection herewith shall
survive the Closing and any investigation at any time made by or on behalf of
the Parties hereto. All such representations and warranties and the
Stockholder's obligations pursuant to Section 7.1(a)(i) and PQC's obligations
pursuant to Section 7.1(b) shall expire on the third anniversary of the Closing
Date, except for claims, if any, asserted in writing prior to such third
anniversary, which shall survive until finally resolved and satisfied in full.
The obligation of the Stockholder pursuant to Section 7.1(a)(ii), (iii), (iv),
(v), (vi), (vii) and (viii) shall survive until six (6) months after the
expiration of the applicable statute of limitations with respect thereto. All
claims and actions for indemnity pursuant to this Article VII shall be asserted
or maintained in writing by a party hereto on or prior to the expiration of such
periods.

         7.4 Confidentiality. The Parties hereto agree to use reasonable efforts
             ----------------
to preserve in full the confidentiality of all confidential business records and
the attorney-client and work-product privileges. In connection therewith, each
Party hereto agrees that:

             (a) it will use all reasonable efforts, in any action, suit or
proceeding in which it has assumed or participated in the defense, to avoid
production of confidential business records; and

             (b) all communications between any Party hereto and counsel
responsible for, or participating in, the defense of any action, suit or
proceeding shall, to the extent possible, be made so as to preserve any
applicable attorney-client or work-product privilege.

         7.5 Remedies Cumulative. Except as otherwise provided herein, the
             --------------------
remedies provided herein shall be cumulative and shall not preclude the
assertion by any Party hereto of any other rights or the seeking of any other
remedies against any other Party hereto.

         7.6 Set-off and Recoupment. Any amount or amounts due from any
             -----------------------
Indemnifying Party to PQC under this Article VII may be paid to PQC, at PQC's
option, by set-off or recoupment against any amounts due to the Indemnifying
Party pursuant to this Agreement or pursuant to any agreement between the
Indemnifying Party and PQC, MCP or any of their respective affiliates. Any such
set-off will be without prejudice to PQC's right to pursue any other remedies at
law or in equity available to it.

warranty, covenant or agreement on the part of PQC or MCP set forth in this
Agreement, or if any representation or warranty of PQC or MCP has become
materially untrue, in either case such that the conditions set forth in Article

any case, a willful breach will be deemed to cause such conditions to be
incapable of being satisfied for purposes of this paragraph (b);

             (c) by PQC upon a material breach of any representation, warranty,
covenant or agreement on the part of the Company or the Stockholder set forth in

materially untrue, in either case such that the conditions set forth in Article
V would be incapable of being satisfied by January 31, 1997; provided, that (i)
in any case, a willful breach will be deemed to cause such conditions to be
incapable of being satisfied for purposes of this paragraph (c). Any breach on
the part of the Company or the Stockholder of the representations and warranties
contained in Article II or the covenants contained in Article IV, which permits
termination of this Agreement shall permit PQC to immediately terminate any
other agreement between the Company or the Stockholder and PQC or MCP; or

             (d) by either Party if the Closing shall not have occurred by
January 31, 1997, or such other date agreed to by the Parties.

request, deliver to the other Parties all documents previously delivered (and
copies thereof in its possession) concerning one another and the transactions
contemplated hereby, and (b) none of the Parties nor any of their respective
Stockholder, directors, officers or agents shall have any liability to the other
Parties, except for any deliberate breach or deliberate omission resulting in a
material breach of any of the provisions of this Agreement. In such case, the
breaching Party shall be liable only for the expenses and costs of the
non-breaching Party, and in no event shall either Party be liable for
anticipated profits or consequential damages. After termination each Party shall
keep confidential all information provided by the others pursuant to this
Agreement which is not in the public domain, shall exercise the same degree of
care in handling such information as it would exercise with similar information
of its own, and shall return any such information upon the other Party's
request.

property relating to the Practice, which listing sets forth a general
description of the leased property or items, the term, the annual rent, any and
all renewal options, and any requirements for the consent of third parties to
assignments thereof.  All such Leases are valid, binding and enforceable in
accordance with their terms and are in full force and effect; no event of
default has occurred which (whether with or without notice, lapse of time or
both or the happening or occurrence of any other event) would constitute a
default thereunder on the part of Seller; and Seller has no knowledge of the
occurrence of any event of default which (whether with or without notice, lapse
of time or both or the happening or occurrence of any other event) would
constitute a default thereunder by any other party.

                          SURVIVAL AND INDEMNIFICATION

     8.01 Indemnification.
          --------------- 

          (a)  Seller shall indemnify, defend, and hold harmless each of MCP and
PQC and their respective subsidiaries and affiliates and their respective
directors, officers, employees and agents or the successor of any of the
forgoing (collectively, "PQC Indemnified Persons"), and reimburse PQC
Indemnified Persons for, from and against all payments,

                                      -19-
<PAGE>
 
demands, claims, suits, judgments, liabilities, losses, costs, damages and
expenses, including, without limitation, interest, penalties and reasonable
attorneys' fees, disbursements and expenses, ("Losses") imposed on or incurred
by PQC Indemnified Persons, which relate to or arise out of (i) breach of any
representation and warranty of, or covenant or agreements to be performed by,
Seller contained in this Agreement, the Affiliation Agreement  or the
Stockholders' Agreement, (ii) any of the liabilities or obligations retained by
Seller pursuant to Section 1.02, (iii) the failure of Seller or of MCP to comply
with any bulk sales laws applicable to the transactions contemplated hereby,
(iv) any Tax liabilities of Seller; and (v) the conduct of the Practice prior to
the Closing Date.  Notwithstanding the foregoing or any other term or condition
contained herein or in any other agreement or instrument referred to herein, the
indemnification obligations of Seller under this Section 8.01(a) and under the
Affiliation Agreement shall be limited, in the aggregate, to the Purchase Price
and to the consideration under the Affiliation Agreement between Seller and PQC
or its affiliates.

     (b) MCP and PQC shall indemnify and hold harmless Seller and its
agents (collectively, "Seller Indemnified Persons" and together with the PQC
Indemnified Persons, the "Indemnified Persons"), and reimburse such Indemnified
Persons for, from, and against all Losses imposed on or incurred, by such
Indemnified Persons which relate to or arise out of (i) breach of any
representation or warranty of, or covenant to be performed by, PQC or MCP, in
each case contained in this Agreement or the Affiliation Agreement and (ii) the
Assumed Liabilities.

          (c) An Indemnified Party shall give prompt written notice to an
indemnifying party (the "Indemnifying Party") of any payments, demands, claims,
suits, judgments, liabilities, losses, costs, damages or expenses (a "Claim") in
respect of which such Indemnifying Party has a duty to provide indemnity to such
Indemnified Party under this Section 8.01, except that any delay or failure so
to notify the Indemnifying Party only shall relieve the Indemnifying Party of
its obligations hereunder to the extent, if at all, that it is prejudiced by
reason of such delay or failure.

          (d) If a Claim is brought or asserted by a third party (a "Third-Party
Claim"), the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all expenses.  The Indemnified Party shall have the right to employ
separate counsel in such Third-Party Claim and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the Indemnified Party.  In the event that the Indemnifying Party, within twenty
(20) days after written notice of any Third-Party Claim, fails to assume the
defense thereof, or in the event the Indemnifying Party fails to demonstrate, to
the reasonable satisfaction of the Indemnified Party, that it has sufficient
assets to meet its indemnification obligations hereunder, the Indemnified Party
shall have the right to undertake the defense, compromise or settlement of such
Third-Party Claim for the account of the Indemnifying Party.  Anything in this
Section 8.01 to the contrary notwithstanding, the Indemnifying Party shall not,
without the Indemnified Party's prior written consent, settle or compromise any
Third-Party Claim or consent to the entry of any judgment with respect to any
Third-Party Claim which would have any adverse effect on the Indemnified Party,
except as provided immediately below.  The Indemnifying Party may, without the
Indemnified Party's prior written consent, settle or compromise any such Third-
Party Claim or consent to entry of any judgment with respect  to

                                      -20-
<PAGE>
 
any Third-Party Claim which requires solely money damages paid by the
Indemnifying Party and which includes as an unconditional term thereof the
release by the claimant or the plaintiff of the Indemnified Party from all
liability in respect of such Third-Party Claim.

          (e) With respect to any Claim other than a Third Party Claim, the
Indemnifying Party shall have thirty (30) days from receipt of written notice
from the Indemnified Party of such Claim within which to respond thereto.  If
the Indemnifying Party does not respond within such thirty (30)-day period, the
Indemnifying Party shall be deemed to have accepted responsibility to make
payment and shall have no further right to contest the validity of such Claim.
If the Indemnifying Party notifies the Indemnified Party within such thirty
(30)-day period that it rejects such Claim in whole or in part, the Indemnified
Party shall be free to pursue such remedies as may be available to the
Indemnified Party under applicable law.

     8.02  Survival of Representations; Claims for Indemnification.  All
           -------------------------------------------------------      
representations and warranties made by the Parties herein or in any instrument
or document furnished in connection herewith shall survive the Closing and any
investigation at any time made by or on behalf of the parties hereto.  All such
representations and warranties and the Seller's obligations pursuant to Sections
8.01(a)(i), (ii) and (iii) and PQC's and MCP's obligations pursuant to Section
8.01(b) shall expire on the third anniversary of the Closing Date, except for
claims, if any, asserted in writing prior to such third anniversary, which shall
survive until finally resolved and satisfied in full.  The obligation of the
Seller pursuant to Section 8.01(a)(iv) and (v) shall survive until six (6)
months after the expiration of the applicable statute of limitations with
respect thereto.  All claims and actions for indemnity pursuant to this Section
8 shall be asserted or maintained in writing by a Party hereto on or prior to
the expiration of such periods.
 
     8.03  Confidentiality.  The Parties hereto agree to use reasonable
           ---------------                                             
efforts to preserve in full the confidentiality of all confidential business
records and the attorney-client and work-product privileges.  In connection
therewith, each Party hereto agrees that:

           (a)  it will use all reasonable efforts, in any action, suit or
proceeding in which it has assumed or participated in the defense, to avoid
production of confidential business records; and

           (b) all communications between any Party hereto and counsel
responsible for, or participating in, the defense of any action, suit or
proceeding shall, to the extent possible, be made so as to preserve any
applicable attorney-client or work-product privilege.

     8.04  Remedies Cumulative.  Except as otherwise provided herein, the
           -------------------                                           
remedies provided herein shall be cumulative and shall not preclude the
assertion by any Party hereto of any other rights or the seeking of any other
remedies against any other Party hereto.

     8.05  Set-off and Recoupment.  Any amount or amounts due from any
           ----------------------                                     
Indemnifying Party to PQC under this Section 8 may be paid to PQC, at PQC's
option, by set-off or recoupment against any amounts due to the Indemnifying
Party pursuant to this Agreement or pursuant to any agreement between the
Indemnifying Party and PQC or any of its affiliates.

                                      -21-
<PAGE>
 
Any such set-off will be without prejudice to PQC's right to pursue any other
remedies at law or in equity available to it.

medical care. If PQC or one of its Affiliates proposes to provide any Integrated
Health Service in the geographic area described on Exhibit B (the "MCP Region"),
PQC shall notify MCP and the Joint Policy Board and MCP shall have 30 days
during which to elect to participate in the provision of such Integrated Health
Service in the MCP Region on such terms as are mutually acceptable to MCP and

the terms of such participation have been approved by the Joint Policy Board. If
MCP does not elect to participate in such Integrated Health Service in the MCP

provide such Integrated Health Service directly or through another entity and
MCP shall have no right to participate in the revenues or income from such
Integrated Health Service. MCP shall not have the right to participate in the

by the Physician Members, the use of which premises shall be subject to the
approval of the Joint Policy Board, such approval not to be unreasonably
withheld. MCP shall not require a Physician Member to practice at any Premise

                 (d)   Disposition. Nothing herein shall be construed as
                       -----------
precluding MCP or any of its Affiliates from selling, lending or otherwise
disposing of all or any part of its real property, improvements, Personal
Property, trade names, trademarks and other intangible property; provided that

                       --------------------------------
annual budgets reflecting the anticipated revenues and expenses, sources and
uses of capital in the practice of each Physician Responsibility Center. Such
budgets shall be presented to the Joint Policy Board at least thirty (30) days
prior to the end of each Fiscal Period. All budgets are subject to the approval
of the Joint Policy Board and MCP. Subject to the powers assigned to the Joint
Policy Board pursuant to Article IV, PQC shall determine the amount and form of
capital to be invested annually in the assets to be utilized by MCP. MCP shall
specify the targeted profit margin for MCP, which shall be reflected in the
overall budget.

         Section 2.5.  Management Information Systems. MCP shall make available
                       ------------------------------

determines to be appropriate. Prior to publication or distribution of marketing
or public relations material or information, MCP shall submit such material to
the Joint Policy Board for its review and approval. MCP shall also design and
implement all other non-local public relations or advertising programs (together
with other professional corporations that utilize the services of Affiliates of
PQC). All public relations and advertising programs shall be conducted in
compliance with applicable standards of medical ethics, laws and regulations. In
the event that there is an adverse incident involving MCP or any Physician
Member or patient, any public statement or announcement by or on behalf of
either MCP or any Physician Member shall be approved in advance by MCP.

         Section 2.8. Personnel. (a) MCP shall retain such non-physician
                      ----------
professional support, including nursing and other non-physician professional
support, and administrative, clerical, secretarial, bookkeeping and collection
personnel, as is reasonably necessary for the efficient conduct of its
operations. The Joint Policy Board shall determine the salaries and benefits of
any Physician Associate. The salaries and benefits of Physician Extender
Employees shall be determined by MCP after consultation with the Joint Policy
Board and the Physician Responsibility Center utilizing such Physician Extender
Employee. Such personnel shall be under the direction, supervision and control
of MCP, except that those personnel performing patient care services shall be
subject to the professional supervision of the Physicians to whom they are
assigned. If any Physician Member is dissatisfied with the services of any
employee who provides services for such Physician Member at the Premises, MCP,
after consultation with the Joint Policy Board, shall in good faith determine
whether the performance of that employee could be brought to acceptable levels
through counsel and assistance, or whether such employee should be terminated.
If MCP determines to retain such employee and the Physician Member is still
dissatisfied with such employee's services after a two (2) month period, MCP
shall either relocate such employee or otherwise cease to utilize such employee
unless MCP reasonably determines that such termination may expose MCP to
liability.

                 (b)  The staffing of MCP shall be governed by the overriding
principle and goal of providing high-quality medical care. Employee assignments
shall be made to attempt to assure consistent and continued rendering of
high-quality medical and support services and to attempt to assure prompt
availability and accessibility of individual medical and support personnel to
the Physician Members in order to develop constant, familiar and routine working
relationships between individual physicians and individual members of the
medical support personnel. MCP shall maintain established working relationships
between Physician Members, Physician Associates, Physician Extender Employees
and non-physician employees wherever possible and MCP shall make every effort
consistent with sound business practices to honor the specific requests of a
Physician Member with regard to the assignment of MCP's employees. MCP agrees
not to terminate or transfer any employee listed on Exhibit D without the
consent of the Joint Policy Board, which consent shall not be unreasonably
withheld.

                 (c)  MCP and each Physician Member agree not to discriminate
unlawfully against any employee of MCP on the basis of race, religion, age, sex,
sexual orientation, disability or national origin, or any other basis proscribed

organizations, preferred provider organizations, exclusive provider
organizations, Medicare, Medicaid and other similar entities (collectively,
"Managed Care Payors"). Each Physician Member appoints MCP and PQC as the
Physician Member's exclusive agents for the negotiation and establishment of
Managed Care Contracts and shall not enter into a Managed Care Contract or
assume any liability under a risk pool or similar arrangement without MCP's and
Joint Policy Board's consent. Except as otherwise provided herein, approval,
disapproval, termination or amendment of any contract or relationship of such
Managed Care Payors with MCP shall be the joint responsibility of the Joint
Policy Board and MCP. The allocation of profits and losses with respect to risk
pools under any Managed Care Contract shall be allocated among Physician
Responsibility Centers in a manner mutually acceptable to each Physician
Responsibility Center which is participating in such Managed Care Contract, or,
in the event that such Physician Responsibility Centers can not agree upon such
allocation, as determined in good faith by MCP and approved by the Joint Policy
Board.

         Section 2.10. Events Excusing Performance. In the event of strikes,
                       ---------------------------
lock-outs, calamities, acts of God, or other events beyond the reasonable
control of MCP, MCP shall not be liable to any Physician Member for failure to
perform any of the services required hereunder and the Physician Members shall
not have the right, as a result of such events and their consequences, to
terminate their Employment Agreements pursuant to Article X of these Terms and
Conditions, for so long as such events continue and for a reasonable period of
time thereafter; provided that MCP uses its reasonable efforts to cure any
nonperformance capable of being cured as soon as practicable.

conditions may, at MCP's sole election, be provided through third parties,
including PQC or any of its Affiliates.

         Section 7.1.   Compensation Pool.  As exclusive compensation for the
                        -----------------
services of the Physician Members under their respective Employment Agreements,
MCP shall establish a compensation pool (the "Compensation Pool") which, on an
annual basis, shall be in an amount determined pursuant to this Section 7.1 and
Section 7.2 and shall be allocated among and distributed to the Physician
Members as provided in Section 7.4. No Physician Member shall be entitled to any
compensation for services under an Employment Agreement or these Terms and
Conditions except as provided in this Article VII. The amount of the
Compensation Pool with respect to each Fiscal Period shall be determined as an
allocation of Stage One Gross Margin between the Compensation Pool and MCP,
which allocation shall be determined as provided below:

         (a)     First, an amount equal to ninety-five percent (95%) of any
         Stage One Gross Margin with respect to any Fiscal Period shall be
         allocated to the Compensation Pool until the total allocation to the
         Compensation Pool for such Fiscal Period equals the ninety-five percent
         (95%) of the Base Compensation Pool Amount (or a proportionally lesser
         amount for any Fiscal Period that is less than twelve (12) calendar
         months) and five percent (5%) of Stage One Gross Margin shall be
         allocated to MCP Allocation Account until the total allocation to the
         MCP Allocation Account equals five percent (5%) of the Base
         Compensation Pool Amount (or a proportionally lesser amount for any
         Fiscal Period that is less than twelve (12) calendar months);

         (b)     Second, any Stage One Gross Margin with respect to any Fiscal
         Period that remain after allocation of the Stage One Gross Margin
         pursuant to Clause (a) ("Stage Two Gross Margin"), shall be allocated
         to the Practice Fund Account up to an amount sufficient to cause the
         balance in such account to be equal to zero;

         (c)     Third, any Stage Two Gross Margin with respect to any Fiscal
         Period that remain after allocation of the amounts pursuant to Clauses
         (a) and (b) shall be allocated twenty percent (20%) to the Compensation
         Pool and eighty percent (80%) to MCP Allocation Account until the
         amount of Stage One or Stage Two Gross Margin allocated to the MCP
         Allocation Account pursuant to Clause

                                      -20-
<PAGE>

         Margin with respect to any Fiscal Period; and

         (d)     Fourth, any Stage Two Gross Margin that remains after
         allocation of the amounts pursuant to (a), (b) and (c) ("Stage Three
         Gross Margin") shall be allocated fifty percent (50%) to the
         Compensation Pool and fifty percent (50%) to the MCP Allocation
         Account.

         The allocation of Stage One, Stage Two and Stage Three Gross Margins to
the Compensation Pool pursuant to this Section 7.1 shall be calculated
separately for each Fiscal Period. Subject to review by the Joint Policy Board,
MCP shall be responsible for the calculating of the amounts of Stage One, Stage
Two and Stage Three Gross Margins to be allocated to each of MCP and the
Compensation Pool. If the Stage One Gross Margin for any Fiscal Period is
negative, such negative amount shall be an Responsibility Center Operating
Expenses for the next following Fiscal Period.

         Section 7.2.   Integrated Health Services.  As additional compensation
                        --------------------------
for the services of the Physician Members under the Employment Agreements and
these Terms and Conditions, IHS Profits (whether a profit or loss) shall be
allocated fifty percent (50%) to the Compensation Pool and fifty percent (50%)
to the MCP Allocation Account; provided, however, that with respect to the
provision of individual Integrated Health Services, MCP and the Joint Policy
Board may approve a different allocation of revenues between the Compensation
Pool and the MCP Profit Account. The allocation of IHS Profits shall be
calculated separately for each Fiscal Period pursuant to this Section 7.2.

         Section 7.3.   Establishment of Budgets for Physician Responsibility
                        -----------------------------------------------------
Centers.  Prior to the end of each Fiscal Period, MCP shall establish a capital
- -------
and operating budget for each Physician Responsibility Center. The capital and
operating budgets for each Physician Member Responsibility Center shall
initially be jointly developed by the Operating Manager and a Physician
representative (the "Representative") of the Physician Responsibility Center.
Targeted Responsibility Center Operating Revenues and Targeted Responsibility
Center Operating Expenses shall be established for the next Fiscal Period with
respect to each Physician Responsibility Center. After the capital and operating
budgets have been established by the Operating Manager and the Representative,
the capital and operating budgets, including the Targeted Responsibility Center
Operating Revenues and Targeted Responsibility Center Operating Expenses for
each Physician Responsibility Center shall be submitted to the Joint Policy
Board. If the Operating Manager and the Representative can not agree upon
capital and operating budgets, each of the Operating Manager and the
Representative shall submit a proposed budget to the Joint Policy Board. The
Joint Policy Board shall approve or modify the budgets or the Targeted
Responsibility Center Operating Revenues and Targeted Responsibility Center
Operating Expenses with respect to any Physician Responsibility Center. At any
point during a Fiscal Period, the Joint Policy Board may, and if the actual
Physician Responsibility Center Net Revenues are below the projected Physician
Responsibility Center Net Revenues for such Physician Responsibility Center
shall, review the budgets for such Physician Responsibility Center and make such
changes to such budgets, including the Base Distributions, as the Joint Policy
Board deems to be appropriate. All capital and operating budgets, and changes
thereto, also shall be subject to the approval of PQC.

         Section 7.4.   Allocation of the Compensation Pool Among Physician
                        ---------------------------------------------------
Members.  (a) On a weekly basis, MCP shall distribute to each Physician
- -------
Responsibility Center (other than a Laboratory Center the contribution from
which will be allocated pursuant to Section 7.4(b)) from the Compensation Pool
an amount equal to 80% of one-fifty-second of the Base Compensation Pool Amount
allocated to such Physician Responsibility Center pursuant to the operating
budget approved by the Joint Policy Board (the "Base Distribution") less the
Deductible Expenses allocated to such Physician Responsibility Center (which
amount shall be distributed to MCP); provided, however. if at any time during a
Fiscal Period MCP determines that the amount of Revenues allocated to the
Compensation Pool for any Fiscal Period may be less than ninety-five percent
(95%) of the Base Compensation Pool Amount for such Fiscal Period, or if

                                      -21-
<PAGE>
 
MCP or the Joint Policy Board determine the Physician Responsibility Center
Operating Expenses for such Fiscal Period will exceed the Targeted Physician
Responsibility Center Operating Expenses for such Physician Responsibility
Center's or the Physician Responsibility Center's Operating Revenues will be
less than the Physician Responsibility Center's Targeted Responsibility Center
Operating Revenues, MCP may, subject to the approval of the Joint Policy Board,
which approval shall be granted unless the Joint Policy Board determines in good
faith that such shortfall in revenues or increase in operating expense is
primarily attributable to MCP, reduce the Base Distributions as MCP determines
to be appropriate in order that the aggregate Base Distributions to all
Physician Responsibility Centers do not exceed the amount of the Compensation
Pool for such Fiscal Period. MCP may, but shall not be required to, advance
money to the Compensation Pool to fund such Base Distributions. Within 45 days
of the end of each three-month period, the MCP shall advise the Compensation
Committee of the amount (the "Variable Distribution Pool"), if any, of the
Compensation Pool that has not been used, or is not reasonably anticipated by
MCP to be needed to fund, the Base Distributions. The Compensation Committee, by
the approval of a majority of the members of such committee, shall determine how
the Variable Distribution Pool, if any, shall be allocated among the Physician
Responsibility Centers. Distributions of the Base Distribution and, if
applicable, the Variable Distribution Pool to a Physician Responsibility Center
shall be allocated among the Physician Members of such Physician Responsibility
Center as determined by a majority of the Physician Members in such Physician
Responsibility Center.

         (b)     Within 45 days after the end of each calendar quarter, MCP
shall distribute to the Physician Responsibility Centers (other than a
Laboratory Center) from the Compensation Pool an amount in aggregate equal to
the net amount contributed to the Compensation Pool with respect to any
Laboratory Centers. If a Laboratory Center Physician Responsibility Center
Operating Revenues are less than the Laboratory Center Physician Responsibility
Center Operating Expenses. the amount of such difference shall be deducted from
distributions payable to the Physician Responsibility Centers pursuant to
Section 7.4(a). The Compensation Committee, by the approval of a majority of the
members of such committee, shall determine how the distributions from the
Compensation Pool with respect to Laboratory Centers shall be allocated among
the Physician Responsibility Centers. Distributions from the Compensation Pool
with respect to Laboratory Centers shall be allocated among the Physician
Members of the Physician Responsibility Centers as determined by a majority of
the Physician Members in such Physician Responsibility Center.

         (c)     The determination of the Compensation Committee and Physician
Responsibility Centers pursuant to this Section 7.4 shall be binding upon MCP
and each Physician Member, and neither PQC nor MCP shall not have any liability
to the Physician Members as a result of any determination of the Compensation
Committee or any Physician Responsibility Center; provided. however, that MCP
shall not be required to make any distribution in accordance with the
determinations of the Compensation Committee or any Physician Responsibility
Center that MCP reasonably believes to conflict with Stark or any other federal
or state statute or regulation. In no event shall any Physician Member be
entitled to any compensation in addition to that determined pursuant to this
Section 7.4 nor shall the aggregate compensation to all Physician Members with
respect to any Fiscal Period exceed the amount of the Compensation Pool for such
Fiscal Period.

         Section 7.5.   Modification to Sections 7.1 and 7.2.  Six months prior
                        ------------------------------------
to the third anniversary of the Effective Date, MCP or a majority of the
Physician Members shall be entitled to require that the provisions of Section
7.1 and Section 7.2 of these Terms and Conditions be amended, effective as of
the third anniversary of the Effective Date (for Fiscal Periods commencing after
such date), so that the economic terms of the Employment Agreements and the
Terms and Conditions, taken as a whole, (and giving effect to any payments or
other compensation received by the Physician Member in connection with their
Affiliation with MCP) are adjusted to reflect the terms being entered into by
independent third parties for similar affiliation and employment relationships
at such time. If MCP and a majority of the Physician Members are not able to
agree upon economic terms that are reflective of then current market practice
for

                                      -22-
<PAGE>
 
similar affiliation and employment relationships, the determination of market
practice shall be submitted to binding arbitration in accordance with Section
11.1.

agrees at all times during the term of the Physician Member's Employment
Agreement and thereafter to hold such Confidential and Proprietary Information

                        --------

                              Term and Termination

         Section 10.1.   Term of Employment.  Each Employment Agreement shall
                         ------------------
have the initial term (the "Employment Period") set forth therein. The
Employment Period under each Employment Agreement shall automatically extend for
an additional twelve (12) months at the end of the initial Employment Period and
on each anniversary of the end of the initial Employment Period thereafter
provided that neither the Physician Member nor MCP has provided at least one
hundred and twenty (120) days notice that the Employment Period shall not be
extended. MCP and each Physician Member intend that these Terms and Conditions
(as they may be amended or modified from time to time) shall be applicable to
any employment relationship between MCP and a Physician Member during the period
of thirty (30) years after the Effective Date.

         Section 10.2.   Termination.  An Employment Agreement shall terminate
                         -----------
or be terminable at the end of the Employment Period, as it may be extended, or

                 -----------
         MCP, subject to approval by the Joint Policy Board, which approval
shall be granted unless the Joint Policy Board determines in good faith that the
Physician Member is not disabled, may terminate an Employment Agreement, upon
written notice to the Physician Member, in the event that the Physician

                                      -25-
<PAGE>
 
Member becomes disabled during the Employment Period through any illness,
injury, accident or condition of either a physical or psychological nature and,
as a result, is unable to perform substantially all of the Physician Member's
duties and responsibilities hereunder for ninety (90) days during any period of
three hundred sixty-five (365) consecutive calendar days. If any question arises
as to whether during any period the Physician Member is so disabled, the
Physician Member shall, at the request of MCP, submit to a medical examination
by a physician selected by MCP, to whom the Physician Member or the Physician
Member's guardian has no reasonable objection, to determine whether the
Physician Member is so disabled. If the Physician Member (or his or her
guardian) shall disagree with the determination of such physician, the Physician
Member within thirty (30) days following the determination by the physician
selected by MCP may submit to a medical examination by a physician selected by
the Physician Member (or his or her guardian). If the determination of such
second physician differs from that of the first, MCP and the Physician Member
(or his or her guardian) within thirty (30) days following the determination by
such physician shall agree upon a third physician, who shall examine the
Physician Member and whose determination shall be conclusive of the issue. If
the Physician Member does not request a second opinion, the determination of the
first physician shall be conclusive of the issue. If this question arises and
the Physician Member does not submit to medical examination, MCP's determination
of the issue shall be binding on the Physician Member.

                 -----------------------------
         MCP may terminate a Physician Member's Employment Agreement for cause
at any time upon ninety (90) day's written notice to the Physician Member
setting forth in reasonable detail the nature of such cause. MCP shall provide
the Physician Member with an opportunity to respond to the notice and discuss
with the Medical Director of MCP the issues identified in the notice, and to
cure the basis for the notice; provided, however, that MCP shall not be required
to provide ninety (90) days notice of an opportunity to cure any cause that in
the reasonable judgment of MCP is not capable of being cured. Cause shall be
determined by MCP in its reasonable judgment and shall include, but not be
limited to: (i) the Physician Member's fraud or dishonesty with respect to MCP,
its employees, patients or visitors; (ii) the Physician Member's suspension or
termination from, or failure to participate, if so requested by MCP, as an
eligible provider in, Medicare, Medicaid or any third-party reimbursement
program, for cause other than the fact of the Physician Member's employment by
MCP; (iii) the Physician Member ceases to maintain without the approval of the
Medical Director, the Board Certifications in effect at any time during the
Employment Period; (iv) the Physician Member's material negligence in the
performance of the Physician Member's duties or responsibilities to MCP; (v) the
Physician Member's breach (or the breach by a professional corporation of which
the Physician Member was formerly a shareholder (other than a breach based upon
a misrepresentation regarding the conduct of another Physician Member)) of any
material term of any agreement entered into in connection with such Physician
Member's Affiliation; (vi) the medical staff membership or clinical privileges
of the Physician Member at any hospital in the Commonwealth of Massachusetts,
the State of Connecticut or any other jurisdiction: (I) shall be revoked or
shall terminate or shall not be renewed or, without the approval of the Medical
Director, shall expire; or (11) shall be reduced to a level which, in the sole
judgment of the Medical Director of MCP, would prevent the Physician Member from
rendering the services contemplated by the Employment Agreement and these Terms
and Conditions in any material respect. (MCP may terminate the Employment
Agreement, upon written notice to the Physician Member, if the Physician
Member's medical staff membership or clinical privileges at any hospital in the
Commonwealth of Massachusetts, the State of Connecticut or any other
jurisdiction shall be suspended (other than (i) during a period of summary
suspension pending hearing and appeal, provided such are timely requested by the
Physician Member or (ii) a nonrecurring, temporary suspension arising solely out
of failure to complete medical records. During any period of summary suspension
of the Physician Member's privileges (other than a nonrecurring, temporary
suspension arising solely out of failure to complete medical records), the
Physician Member's employment shall be suspended pending hearing and appeal
timely requested by the Physician Member; compensation and benefits shall be
continued to the extent provided by policies in effect at the time); (vii) the

which the Physician Member is licensed; (viii) the Physician Member ceases to

turpitude, (xi) the Physician Member is penalized with civil monetary fines or
assessment under any federal or state law involving Medicare, Medicaid or any
third- party reimbursement program (other than as a result of MCP's act or
omission); or (xii) the Physician Member (I) engages in any conduct or is
formally accused of conduct for which the Physician Member's license to practice
medicine reasonably would be expected to be subject to revocation or suspension,
whether or not actually revoked or suspended, or (II) is otherwise disciplined
by any licensing, regulatory or professional entity or institution, the result
of any of which event described in clause (I) or (II) does, or reasonably would
be expected to, materially adversely affect MCP or significantly impair the
ability of MCP to perform medical services in an amount and of a nature
consistent with the medical services performed at the time of such action.

         Physician Member shall be entitled, at the Physician Member's cost and
         with the written approval of the patient, to make copies of the patient
         record for any patient to whom the Physician Member provided services.
         If requested by a patient, MCP shall transfer each patient's medical
         records as directed by the patient.

                 (vi)    MCP agrees that it will not interfere with the
         Physician Member's ability to reactivate any provider numbers under any
         Managed Care Contract that were assigned to the Physician Member prior
         to Affiliation. MCP shall not be obligated to terminate or transfer any
         provider number that it possesses and shall not be liable to the
         Physician Member if the Physician Member is unable to establish or re-
         establish provider status under any Managed Care Contract.

on the Termination Date or (b) on a date mutually acceptable to MCP and the
Physician Member that shall be within one hundred and eighty (180) days after
receipt of a termination notice (or such later date as is necessary for MCP to
obtain lessor consents to the assignment to the Physician Member of leases of
real and personal property to be assumed by the Physician Member). Subject to
the conditions set forth below, at the Purchased Closing, MCP, PQC and/or their
Affiliates, as the case may be, shall transfer and assign the Purchase Assets or
the Section 10.5 Assets, as the case may be, to the Physician Member and in
consideration therefor, the Physician Member shall (a) pay to MCP the purchase
price in cash and assume, if applicable, Physician Related Liabilities. Each of
MCP and the Physician Member shall execute such documents or instruments as is
reasonably necessary, in the opinion of MCP, the Physician Member and their

contained herein to the contrary, MCP shall not be obligated to sell the assets
to the Physician Member if Physician Member is not able to pay the purchase
price therefor pursuant to the terms set forth above at the Purchase Closing. In
such event, the Physician Member shall surrender the assets in the Physician
Member's possession or control to MCP as of the Purchase Closing. If a Physician
Member fails to so surrender the assets, MCP may, without prejudice to any other
remedy which it may have hereunder or otherwise, enter the Premises and take
possession of the assets and expel or remove the Physician Member and any other
person who may be occupying the Premises or any part thereof, by force if

                         -----------
and any Physician Member arising under or relating to these Terms and Conditions
or any breach thereof (including the question of whether any particular matter
is arbitrable hereunder) shall be settled by arbitration in accordance with the
commercial arbitration rules of the American Arbitration Association then in
effect; provided, however, that no provision of these Terms and Conditions shall
be modified, deleted or added by reason of such arbitration; provided, further,
that no controversy or claim that may be brought before the Dispute Resolution
Subcommittee and no decision of such Subcommittee shall be submitted to
arbitration. MCP and each Physician Member agrees (subject to judicial review)
to abide by all awards rendered in such arbitration proceedings, and all such
awards may be filed by the prevailing party in any federal or state court having
proper jurisdiction, as a basis for judgment in the issuance of execution

permitted by the Federal Rules of Civil Procedure and the relevant arbitration
statute. Such arbitration shall be initiated by either MCP or a Physician Member
by serving a written demand on the other party and the Joint Policy Board
stating the substance of the controversy and the contention of the party
requesting arbitration. The American Arbitration Association shall appoint or
provide the procedure for the determination of a single neutral arbitrator who
shall be a fit and impartial person. The fees and costs of the arbitrator and
related expenses of arbitration shall be borne by the nonprevailing party. If
the arbitrator determines that neither party has substantially prevailed, the

or promulgated after the Effective Date are interpreted by judicial decision, a
regulatory agency or legal counsel in such a manner as to indicate that these

regulations, the Joint Policy Board and MCP shall agree upon such amendments to
these Terms and Conditions as necessary to preserve the underlying economic and
financial arrangements between the Physician Members and MCP and without
substantial economic detriment to either MCP or Physician Members. Any such
amendment approved by the Joint Policy Board shall be binding upon each
Physician Member. To the extent any act or service required of MCP should be
construed or deemed, by any governmental authority, agency or court, to
constitute the practice of medicine by PQC, the performance of said act or
service by MCP shall be deemed waived and forever unenforceable and the
provisions of this Section 11.2 shall be applicable. None of MCP nor any
Physician Member shall claim or assert illegality as a defense to the
enforcement of these Terms and Conditions or any provision hereof; instead, any
such purported illegality shall be resolved pursuant to the terms of this

                         ------------------------------
any Physician Member shall by any act, delay, indulgence, omission or otherwise
be deemed to have waived any right or remedy hereunder or to have acquiesced in
any default in or breach of any of the terms and conditions hereof. No failure
to exercise, nor any delay in exercising, on the part of either MCP, PQC or any
Physician Member, any right, power or privilege hereunder shall operate as a
waiver thereof. No single or partial exercise of any right, power or privilege
shall operate as a waiver thereof. No single or partial exercise of any right,
power or privilege hereunder shall preclude any other or further exercise
thereof or the exercise of any other right. power or privilege. No remedy set
forth in this these Terms and Conditions or the Employment Agreements or
otherwise conferred upon or reserved to either MCP or any Physician Member shall
be considered exclusive of any other remedy available to either MCP or any
Physician Member, but the same shall be distinct, separate and cumulative and
may be exercised from time to time as often as occasion may arise or as may be
deemed expedient.

         Section 11.5.   Availability of Certain Documents.  The parties agree,
                         ---------------------------------
to the extent required by law necessary to permit receipt of reimbursement for

Services, the Comptroller General of the General Accounting Office, or their

                      ADDENDUM DATED AS OF DECEMBER 31,1996
             TO GENERAL TERMS AND CONDITIONS OF PHYSICIAN EMPLOYMENT


         Section 1.      The General Terms and Conditions are amended to add an
additional Physician Responsibility Center as follows:

         Responsibility Center I:           Ronald H. Berger, M.D.
                                            John A. Egeihofer, M.D.
                                            David R. Fanti, M.D.
                                            James Hession, M.D.

         Responsibility Center J:           Barry Izenstein, M.D.

         Section 2.      Until August 30, 1999, a separate Compensation Pool
(the "Additional Responsibility Centers Pool,") shall be established with
respect to Responsibility Centers I, J and any other Physician Responsibility
Centers designated by the Joint Policy Board as participating in the Additional
Responsibility Centers Pool (the "Additional Responsibility Centers") and
Section 7.1 of the General Terms and Conditions shall not apply to the
Additional Responsibility Centers. Except with respect to Integrated Health
Services, all Stage One Gross Margin attributable to the Additional
Responsibility Centers Pool and MCP, as provided below and shall constitute the
exclusive compensation for the services of the Physician Member in the
additional Responsibility Centers under their respective Employment Agreements.
The Physician Members in the Additional Responsibility Centers shall not be
entitled to participate in the Compensation Pool prior to August 30, 1999 except
to the extent that the Physician Members in an Additional Responsibility Center
are allocated any portion of the Compensation Pool attributable to a Laboratory
Center pursuant Section 7.4(b) or to Integrated Health Services pursuant to
Section 7.2. No Physician Member in the Additional Responsibility Centers shall
be entitled to any compensation for services under an Employment Agreement or
the Terms and Conditions except as provided in Article VII as modified by this
Addendum. No Physician Member who is not included in an Additional
Responsibility Center shall be entitled to any portion of the Additional
Responsibility Centers Pool or to any Stage One Gross Margin attributable to an
Additional Responsibility Center allocated to the Compensation Pool.

         The amount of the Additional Responsibility Centers Pool with respect
to each Fiscal Period shall be determined as an allocation of Stage One Gross
Margin attributable to the Additional Responsibility Centers between the
Additional Responsibility Centers Pool and MCP, which allocation shall be
determined as provided below:

         (a)     First, an amount equal to eighty percent (80%) of any Stage One
         Gross Margin attributable to the Additional Responsibility Centers with
         respect to any Fiscal Period shall be allocated to the Additional
         Responsibility Centers Pool until the total allocation to the
         Additional Responsibility Center Pool for such Fiscal Period equals
         eighty percent (80%) of the Base Compensation Pool Amount with respect
         to the Additional Responsibility Centers (or a proportionally lesser
         amount for any Fiscal Period that is less than twelve (12) calendar
         months) and twenty percent (20%) of Stage One Gross Margin attributable
         to the Additional Responsibility Centers shall be allocated to MCP
         Allocation Account until the total allocation to the MCP Allocation
         Account equals twenty percent (20%) of the Base Compensation Pool
         Amount with respect to the Additional Responsibility Centers (or a
         proportionally lesser amount for any Fiscal Period that is less than
         twelve (12) calendar months);

                                      
<PAGE>
 
         (b)     Second, any Stage One Gross Margin attributable to Additional
         Responsibility Centers with respect to any Fiscal Period that remain
         after allocation of the Stage One Gross Margin pursuant to Clause (a)
         ("Additional Responsibility Centers Stage Two Gross Margin"), shall be
         allocated to the Practice Fund Account proportionately with the
         contributions of other Physician Responsible Centers up to an amount
         sufficient to cause the balance in such account to be equal to zero;
         and

         (c)     Third, any Additional Responsibility Centers Stage Two Gross
         margin that remains after allocation of the amounts pursuant to (a) and
         (b) ("the Additional Responsibility Centers Stage Three Gross Margin")
         shall be allocated fifty percent (50%) to the Additional Responsibility
         Centers Pool and fifty percent (50%) to the MCP Allocation Account.

         The allocation of Stage One, Stage Two and Stage Three Gross Margins to
the Additional Responsibility Centers Pool shall be calculated separately for
each Fiscal Period. Subject to review by the Joint Policy Board, MCP shall be
responsible for calculating the amounts of Stage One, Stage Two and Stage Three
Gross Margins to be allocated to each of MCP and the Additional Responsibility
Centers Pool. If the Stage One Gross Margin attributable to the Additional
Responsibility Centers for any Fiscal Period is negative, such negative amount
shall be an Additional Responsibility Centers Operating Expenses for the next
following Fiscal Period.

         Section 3.      Until August 30, 1999, Section 7.4(a) of the General
Terms and Conditions shall not apply to the Additional Responsibility Centers
and the following provision shall apply in lieu thereof:

Section 7.4. Allocation of the Compensation Pool among Physician Members in each
             -------------------------------------------------------------------
Additional Responsibility Center. (a) On a weekly basis, MCP shall distribute to
- --------------------------------
each Additional Responsibility Center from the Additional Responsibility Centers
Pool an amount equal to 80% of one-fifty-second of the Base Compensation Pool
Amount for the Additional Responsibility Centers (the "Base Distribution") less
the Deductible Expenses allocated to the Additional Responsibility Centers
(which amount shall be distributed to MCP); provided, however, if at any time
during a Fiscal Period MCP reasonably determines that the amount of Revenues
allocated to the Additional Responsibility Centers Pool for any Fiscal Period
may be less than eighty percent (80%) of the Additional Responsibility Centers'
Base Compensation Pool Amount for such Fiscal Period maybe less than eighty
percent (80%) of the Additional Responsibility Period, or if MCP or the Joint
Policy Board determines an Additional Responsibility Center's Physician
Responsibility Center Operating Expenses for such Fiscal Period will exceed such
Additional Responsibility Center's Targeted Physician Responsibility Center
Operating Expenses or an Additional Responsibility Center's Operating Revenues
will be less than such Responsibility Center's Targeted Responsibility Center
Operating Revenues, MCP may, subject to the approval of the Joint Policy Board,
which approval shall be granted unless the Joint Policy Board determines in good
faith that such shortfall in revenues or increase in operating expense is
primarily attributable to MCP, reduce the Base Distribution of an Additional
Responsibility Center as MCP determines to be appropriate in order that the
aggregate Base Distributions to the Additional Responsibility Centers do not
exceed the amount of the Additional Responsibility Centers Pool for such Fiscal
Period. MCP may, but shall not be required to, advance money to the Additional
Responsibility Centers Pool to fund such Base Distributions. Within 45 days of
the end of each three-month period, MCP shall advise the Compensation Committee
of the amount (the "Additional Variable Distribution Pool"), if any, of the
Additional Responsibility Centers Pool that has not been used, or is not
reasonably anticipated by MCP to be needed to fund, the Base Distributions. The
Compensation Committee, by the approval of a majority of the members of such
committee, shall determine how the Additional Variable Distribution Pool, if
any, shall be allocated among the Additional Responsibility Centers.
Distributions of the Base Distribution and, if applicable, the Additional
Variable Distribution Pool to an Additional Responsibility Center shall be
allocated among the Physician Members of such Additional Responsibility Center
as determined by a majority of the Physician Members in such Additional
Responsibility Center.

         Section 4.      From and after August 30, 1999, Article VII in its
entirety shall apply to Responsibility Center I and the provisions of Section 2

breaching party shall be liable only for the expenses and costs of the non-
breaching party, and in no event shall either party be liable for anticipated
profits or consequential damages.

          (b) After termination each party shall keep confidential all
information provided by the others pursuant to this Agreement which is not in

care in handling such information as it would exercise with similar information

                                   ARTICLE VI

                          SURVIVAL AND INDEMNIFICATION

     6.01 Indemnification.
          --------------- 

          (a) Physician shall indemnify, defend, and hold harmless each of MCP
and PQC and their respective subsidiaries and affiliates and their respective
directors, officers, employees and agents or the successor of any of the
forgoing (collectively, "PQC Indemnified Persons"), and reimburse any PQC
Indemnified Persons for, from and against all payments, demands, claims, suits,
judgments, liabilities, losses, costs, damages and expenses, including, without
limitation, interest, penalties and reasonable attorneys' fees, disbursements
and expenses, ("Damages") imposed on or incurred by PQC Indemnified Persons,
directly or indirectly, which relate to or arise out of (i) breach of any
representation and warranty of, or covenant or agreements to be performed by,
Physician contained in this Agreement, the Asset Purchase Agreement or the
Stockholders' Agreement, (ii) any of the liabilities or obligations retained by
Physician pursuant to the Asset Purchase Agreement, (iii) the failure of
Physician or of MCP to comply with any bulk sales laws applicable to the
transactions contemplated hereby, (iv) any Tax liabilities of Physician; and (v)
the conduct of the Practice prior to the Closing Date.  Notwithstanding the
foregoing or any other term or condition contained herein or in any other
agreement or instrument referred to herein, the indemnification obligations of
Physician under this Section 6.01(a) and under the Asset Purchase Agreement
shall be limited, in the aggregate, to the purchase price under the Asset
Purchase Agreement and to the consideration under this Agreement.

          (b) MCP and PQC shall indemnify and hold harmless Physician
(collectively, "Physician Indemnified Persons" and together with the PQC
Indemnified Persons, the "Indemnified Persons"), and reimburse such Physician
Indemnified Persons for, from, and against all Damages imposed on or incurred,
directly or indirectly, by such Physician Indemnified Persons which arise out of
or relate to (i) breach of any representation or warranty of, or covenant to be
performed by, PQC or MCP, in each case contained in this Agreement or the Asset
Purchase Agreement and (ii) the Assumed Liabilities (as defined in the Asset
Purchase Agreement).

          (c) An Indemnified Party shall give prompt written notice to an
indemnifying party (the "Indemnifying Party") of any payments, demands, claims,
suits, judgments, liabilities, losses, costs, damages or expenses (a "Claim") in
respect of which such Indemnifying Party has a duty to provide indemnity to such
Indemnified Party under this Section 6.01, except that any delay or failure so
to notify the Indemnifying Party only shall relieve the Indemnifying Party of
its obligations hereunder to the extent, if at all, that it is prejudiced by
reason of such delay or failure.

          (d) If a Claim is brought or asserted by a third party (a "Third-Party
Claim"), the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all expenses.  The Indemnified Party shall have the right to employ
separate counsel in such Third-Party Claim and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the Indemnified Party.  In the event that the Indemnifying Party, within twenty
(20) days after written notice of any Third-Party Claim, fails to assume the
defense thereof, or in the event the Indemnifying Party fails to demonstrate, to
the reasonable satisfaction of the Indemnified Party, that it has sufficient
assets to meet its indemnification obligations hereunder, the Indemnified Party
shall have the right to undertake the defense, compromise or settlement of such
Third-Party Claim for the account of the Indemnifying

                                      -4-
<PAGE>
 
Party.  Anything in this Section 6.01(d) to the contrary notwithstanding, the
Indemnifying Party shall not, without the Indemnified Party's prior written
consent, settle or compromise any Third-Party Claim or consent to the entry of
any judgment with respect to any Third-Party Claim which would have any adverse
effect on the Indemnified Party, except as provided immediately below.  The
Indemnifying Party may, without the Indemnified Party's prior written consent,
settle or compromise any such Third-Party Claim or consent to entry of any
judgment with respect to any Third-Party Claim which requires solely money
damages paid by the Indemnifying Party and which includes as an unconditional
term thereof the release by the claimant or the plaintiff of the Indemnified
Party from all liability in respect of such Third-Party Claim.

          (e) With respect to any Claim other than a Third Party Claim, the
Indemnifying Party shall have thirty (30) days from receipt of written notice
from the Indemnified Party of such Claim within which to respond thereto.  If
the Indemnifying Party does not respond within such thirty (30)-day period, the
Indemnifying Party shall be deemed to have accepted responsibility to make
payment and shall have no further right to contest the validity of such Claim.
If the Indemnifying Party notifies the Indemnified Party within such thirty
(30)-day period that it rejects such Claim in whole or in part, the Indemnified
Party shall be free to pursue such remedies as may be available to the
Indemnified Party under applicable law.

     6.02  Survival of Representations; Claims for Indemnification.  All
           -------------------------------------------------------      
representations and warranties made by the parties herein or in any instrument
or document furnished in connection herewith shall survive the Closing and any
investigation at any time made by or on behalf of the parties hereto.  All such
representations and warranties and the Physician's obligations pursuant to
Sections 6.1(a)(i), (ii) and (iii) and the PQC's and MCP's obligations pursuant
to Section 6.1(b) shall expire on the third anniversary of the Closing Date,
except for claims, if any, asserted in writing prior to such third anniversary,
which shall survive until finally resolved and satisfied in full.  The
obligation of the Physician pursuant to Section 6.1(a)(iv) and (v) shall survive
until six (6) months after the expiration of the applicable statute of
limitations with respect thereto.  All claims and actions for indemnity pursuant
to this Section 6 shall be asserted or maintained in writing by a party hereto
on or prior to the expiration of such periods.
 
     6.03 Confidentiality.  The Parties hereto agree to use reasonable
          ---------------                                             
efforts to preserve in full the confidentiality of all confidential business
records and the attorney-client and work-product privileges.  In connection
therewith, each party hereto agrees that:

          (a) it will use all reasonable efforts, in any action, suit or
proceeding in which it has assumed or participated in the defense, to avoid
production of confidential business records; and

          (b) all communications between any party hereto and counsel
responsible for, or participating in, the defense of any action, suit or
proceeding shall, to the extent possible, be made so as to preserve any
applicable attorney-client or work-product privilege.

     6.04 Remedies Cumulative.  Except as otherwise provided herein, the
          -------------------                                           
remedies provided herein shall be cumulative and shall not preclude the
assertion by any Party hereto of any other rights or the seeking of any other
remedies against any other Party hereto.

     6.05 Set-off and Recoupment.  Any amount or amounts due from any
          ----------------------                                     
Indemnifying Party to PQC under this Article VI may be paid to PQC, at PQC's
option, by set-off or recoupment against any amounts due to the Indemnifying
Party pursuant to this Agreement or pursuant to any agreement between the
Indemnifying Party and PQC, MCP or any of their respective affiliates.  Any such
set-off will be without prejudice to PQC's right to pursue any other remedies at
law or in equity available to it.

but such waiver shall not operate as a waiver of, or estoppel with respect to,

constitute a waiver of such Party's right to enforce any provision hereof or to
take any such action.

     10.  This Agreement may be amended or modified only by a written instrument

the transfer of the Shares to the Successor Shareholder. The Shareholder's only
remedy for the failure of the Successor Shareholder to pay the purchase price
for the Shares shall be money damages, and in no way shall such failure
jeopardize the temporary or permanent transfer of any rights as to the Shares.

involving alleged medical malpractice by a physician employee of MCP, and PQC
shall indemnify Shareholder for any costs and expenses arising out of such a
proceeding in the event such costs and expenses are not reimbursed pursuant to
such policy.

     (b)    Notification and Defense of Claim. Not later than thirty (30) days
            ---------------------------------                                 
after receipt by Shareholder of notice of the commencement of any action, suit
or proceeding, Shareholder will, if a claim in respect thereof is to be made
against PQC under this Agreement, notify PQC of the commencement thereof but the
omission so to notify PQC will not relieve PQC from any liability which it may
have to Shareholder otherwise than under this Agreement. With respect to any
such action, suit, or proceeding as to which Shareholder notifies PQC of the
commencement thereof:

     (i)    PQC will be entitled to participate therein at its own expense;

     (ii)   Except as otherwise provided below, to the extent that it may wish,
PQC jointly with any other indemnifying party similarly notified will be
entitled to assume the defense thereof, with counsel reasonably satisfactory to
Shareholder.  After notice from PQC to Shareholder of its election so as to
assume the defense thereof, PQC will not be liable to Shareholder under this
Agreement for any legal or other expenses subsequently incurred by Shareholder
in connection with the defense thereof other than reasonable costs of
investigation or as otherwise provided below. Shareholder shall have the right
to employ the Shareholder's counsel in such action, suit, or proceeding but the
fees and expenses of such counsel incurred after notice from PQC of its
assumption of the defense thereof shall be at the expense of Shareholder unless
(A) the employment of counsel by Shareholder has been authorized by PQC, (B)
Shareholder shall have reasonably concluded that there may be a conflict of
interest between PQC and Shareholder in the conduct of the defense of such
action or (C) PQC shall not in fact have reasonably promptly employed counsel to
assume the defense of such action, in each of which cases the fees and expenses
of Shareholder's separate counsel shall be at the expense of PQC. PQC shall not
be entitled to assume the defense of any action, suit, or proceeding brought by
or on behalf of PQC or as to which Shareholder shall have made the conclusion
provided for in (B) above; and

     (iii)  PQC shall not be liable to indemnify Shareholder under this
Agreement for any amounts paid in settlement of any action or claim effected
without its written consent. PQC shall be permitted to settle any action except
that it shall not settle any action or claim in any manner which would impose
any penalty or limitation on Shareholder without Shareholder's written consent.
Neither PQC nor Shareholder will unreasonably withhold its consent to any
proposed settlement.

covenants as follows:

     (a) The Purchaser is purchasing the Shares for his own account for
investment only, and not with a view to, or for sale in connection with, any
distribution of the Shares in violation of the Securities Act of 1933 (the
"Securities Act"), or any rule or regulation under the Securities Act.

     (b) The Purchaser has had such opportunity as he has deemed adequate to
obtain from representatives of the Company such information as is necessary to
permit him to evaluate the merits and risks of his investment in the Company.

investment matters to be able to evaluate the risks involved in the purchase of
the Shares and to make an informed investment decision with respect to such

is able to bear the economic risk of holding such Shares for an indefinite
period.

<PAGE>
 
Securities Act, (ii) the Shares cannot be sold, transferred or otherwise
disposed of unless they are subsequently registered under the Securities Act or
an exemption from registration is then available; (iii) in any event, the
exemption from registration under Rule 144 will not be available for at least
two years and even then will not be available unless a public market then exists
for the Common Stock, adequate information concerning the Company is then
available to the public, and other terms and conditions of Rule 144 are complied

certificate representing the Shares:

         transferred or otherwise disposed of in the absence of an effective
         registration statement under such Act or an opinion of counsel
         satisfactory to the corporation to the effect that such registration is
         not required."

     8.  Adjustments for Stock Splits, Stock Dividends, etc.
         -------------------------------------------------- 

     (a) If from time to time during the term of the Purchase Option there is
any stock split-up, stock dividend, stock distribution or other reclassification
of the Common Stock of the Company, any and all new, substituted or additional
securities to which the Purchaser is entitled by reason of his ownership of the
Shares shall be immediately subject to the Purchase Option, the restrictions on
transfer and other provisions of this Agreement in the same manner and to the
same extent as the Shares, and the Option Price shall be appropriately adjusted.

the Company receive by reason of any distribution in total or partial
liquidation, securities of another corporation, or other property (including
cash), pursuant to any merger of the Company or acquisition of its assets, then
the rights of the Company under this Agreement shall inure to the benefit of the
Company's successor and this Agreement shall apply to the securities or other
property received upon such conversion, exchange or distribution in the same
manner and to the same extent as the Shares.

     9.   Withholding Taxes.

Shares by the Purchaser.

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

         CREDIT AGREEMENT, dated as of January 16, 1997, among PHYSICIANS
QUALITY CARE, INC., a Delaware corporation (the "Borrower"), the lenders from
time to time party hereto (each, a "Bank" and, collectively, the "Banks"), and
BANKERS TRUST COMPANY, as Agent (in such capacity, the "Agent"). Unless
otherwise defined herein, all capitalized terms used herein and defined in
Section 9 are used herein as so defined.

                                   WITNESSETH:

         WHEREAS, subject to and upon the terms and conditions herein set forth,
the Banks are willing to make available the credit facility provided for herein;

         NOW, THEREFORE, IT IS AGREED:

         SECTION 1.  Amount and Terms of Credit.
                     ---------------------------
         1.01 Revolving Loan Commitments. Subject to and upon the terms and
              --------------------------
conditions herein set forth, each Bank severally agrees to make a loan or loans
under the Revolving Loan Facility (each, a "Revolving Loan" and, collectively,
the "Revolving Loans") to the Borrower, which Revolving Loans (i) may be
incurred by the Borrower at any time and from time to time on and after the
Initial Borrowing Date and prior to the Final Maturity Date, (ii) shall be
denominated in U.S. Dollars, (iii) except as hereinafter provided, may, at the
option of the Borrower, be incurred and maintained as and/or converted into Base
Rate Loans or Eurodollar Loans, provided, that all Revolving Loans made as part
of the same Borrowing shall, unless otherwise specifically provided herein,
consist of Revolving Loans of the same Type, (iv) may be repaid and reborrowed
in accordance with the provisions hereof and (v) shall not exceed for any Bank
at any time outstanding that aggregate principal amount which, when combined
with the aggregate principal amount of all other then outstanding Revolving
Loans made by such Bank, equals the Revolving Loan Commitment of such Bank at
such time.

         1.02 Minimum Borrowing Amounts, etc. The aggregate principal amount of
              ------------------------------
each Borrowing of Revolving Loans shall not be less than the Minimum Borrowing
Amount applicable thereto. More than one Borrowing may be incurred on any day;
provided, that 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 incur
              -------------------
(x) Eurodollar Loans hereunder, the Borrower shall give the Agent at its Notice
Office at least three Business Days' prior written notice (or telephonic notice
promptly confirmed in writing) of each Eurodollar Loan to be incurred hereunder
and (y) Base Rate Loans hereunder, the Borrower shall give the Agent at its
Notice Office written notice (or telephonic notice promptly confirmed in
writing) thereof no later than the date on which each Base Rate Loan is to be
incurred hereunder, provided that (in each case) any such notice shall be deemed
                    --------
to have been given on a certain day only if given before 11:00 A.M. (New York
time) on such day. Each such notice (each, a "Notice of Borrowing") shall,
except as provided in Section 1.10, be irrevocable, and, in the case of each
written notice and each confirmation of telephonic notice, shall be in the form
of Exhibit A, appropriately completed to specify (i) the

                                       -1-
<PAGE>
 
aggregate principal amount of the Revolving Loans to be made pursuant to such
Borrowing, (ii) the date of such Borrowing (which shall be a Business Day),
(iii) whether the respective Borrowing shall consist of Base Rate Loans or, to
the extent permitted hereunder, Eurodollar Loans and, if Eurodollar Loans, the
Interest Period to be initially applicable thereto and (iv) the specific
purposes for which the proceeds of such Revolving Loans are to be used. The
Agent shall promptly give each Bank written notice (or telephonic notice
promptly confirmed in writing) of each proposed Borrowing, of such Bank's
proportionate share thereof, if any, and of the other matters covered by the
Notice of Borrowing.

         (b) Without in any way limiting the obligation of the Borrower to
confirm in writing any telephonic notice permitted to be given hereunder, the
Agent may prior to receipt of written confirmation act without liability upon
the basis of such telephonic notice, believed by the Agent in good faith to be
from an Authorized Officer of the Borrower. In each such case, the Borrower
hereby waives the right to dispute the Agent's record of the terms of such
telephonic notice.

         1.04 Disbursement of Funds. (a) No later than 1:00 P.M. (New York time)
              ---------------------
(or 2:00 P.M. (New York time) in the case of a Borrowing of Base Rate Loans made
on same day notice) on the date specified in each Notice of Borrowing, each Bank
will make available its pro rata share, if any, of each Borrowing requested to
be made on such date in the manner provided below. All amounts shall be made
available to the Agent in U.S. Dollars and immediately available funds at the
Payment Office and the Agent promptly will make available to the Borrower by
depositing to its account at the Payment Office the aggregate of the amounts so
made available in the type of funds received. Unless the Agent shall have been
notified by any Bank prior to the date of Borrowing that such Bank does not
intend to make available to the Agent its portion of the Borrowing or Borrowings
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, in
reliance upon such assumption, may (in its sole discretion and without any
obligation to do so) make available to the Borrower a corresponding amount. If
such corresponding amount is not in fact made available to the Agent by such
Bank and the Agent has made available same to the Borrower, the Agent shall be
entitled to recover such corresponding amount 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 the Borrower shall immediately
pay such corresponding amount to the Agent. The Agent shall also be entitled to
recover from the Bank 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 to the date such
corresponding amount is recovered by the Agent, at a rate per annum equal to (x)
if paid by such Bank, the overnight Federal Funds rate or (y) if paid by the
Borrower, the then applicable rate of interest, calculated in accordance with
Section 1.08, for the respective Revolving Loans.

         (b) Nothing herein shall be deemed to relieve any Bank from its
obligation to fulfill its commitments hereunder or to prejudice any rights which
the Borrower may have against any Bank as a result of any default by such Bank
hereunder.

                                       -2-
<PAGE>
 
         1.05 Notes. (a) The Borrower's obligation to pay the principal of, and
              -----
interest on, all the Revolving Loans made to it by each Bank shall be evidenced
by a promissory note substantially in the form of Exhibit B with blanks
appropriately completed in conformity herewith (each, a "Revolving Note" and,
collectively, the "Revolving Notes").

         (b) The Revolving Note issued to each Bank shall (i) be executed by the
Borrower, (ii) be payable to the order of such Bank or its registered assigns
and be dated the Initial Borrowing Date, (iii) be in a stated principal amount
equal to the Revolving Loan Commitment of such Bank and be payable in the
principal amount of the Revolving Loans evidenced thereby, (iv) mature on the
Final Maturity Date, (v) bear interest as provided in the appropriate clause of
Section 1.08 in respect of the Base Rate Loans and Eurodollar Loans, as the case
may be, evidenced thereby, (vi) be subject to voluntary prepayment as provided
in Section 3.01, and mandatory repayment as provided in Section 3.02, and (vii)
be entitled to the benefits of this Agreement and the other Credit Documents.

         (c) Each Bank will note on its internal records the amount of each
Revolving Loan made by it and each payment in respect thereof and will prior to
any transfer of any of its Revolving Notes endorse on the reverse side thereof
the outstanding principal amount of Revolving Loans evidenced thereby. Failure
to make any such notation shall not affect the Borrower's obligations in respect
of such Revolving Loans.

         1.06 Conversions. The Borrower shall have the option to convert on any
              -----------
Business Day occurring on or after the Initial Borrowing Date, all or a portion
at least equal to the applicable Minimum Borrowing Amount of the outstanding
principal amount of the Revolving Loans owing by the Borrower into a Borrowing
or Borrowings of another Type of Revolving Loan; provided, that (i) except as
otherwise provided in Section 1.10(b), no partial conversion of a Borrowing of
Eurodollar Loans shall reduce the outstanding principal amount of the Eurodollar
Loans made pursuant to such Borrowing to less than the Minimum Borrowing Amount
applicable thereto, (ii) Base Rate Loans may only be converted into Eurodollar
Loans if no payment Default or Event of Default is in existence on the date of
the conversion, and (iii) Borrowings of Eurodollar Loans resulting from this
Section 1.06 shall be limited in number as provided in Section 1.02. Each such
conversion shall be effected by the Borrower by giving the Agent at its Notice
Office, prior to 11:00 A.M. (New York time), at least three Business Days' (or
one Business Day's in the case of a conversion into Base Rate Loans) prior
written notice (or telephonic notice promptly confirmed in writing) (each, a
"Notice of Conversion") specifying the Revolving Loans to be so converted, the
Type of Revolving Loans to be converted into and, if to be converted into a
Borrowing of 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 Revolving Loans.

         1.07 Pro Rata Borrowings. All Borrowings of Revolving Loans under this
              -------------------
Agreement shall be made by the Banks pro rata on the basis of their Revolving
                                     --- ----
Loan Commitments. It is understood that no Bank shall be responsible for any
default by any other Bank of its obligation to make Revolving Loans hereunder
and that each Bank shall be obligated to make the Revolving Loans to be made by
it hereunder, regardless of the failure of any other Bank to fulfill its
commitments hereunder.

                                       -3-
<PAGE>
 
         1.08 Interest. (a) The unpaid principal amount of each Base Rate Loan
              --------
shall bear interest from the date of the Borrowing thereof until the earlier of
(i) the maturity (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 the Applicable
Base Rate Margin plus the Base Rate in effect from time to time.

         (b) The unpaid principal amount of each Eurodollar Loan shall bear
interest from the date of the Borrowing thereof until the earlier of (i) the
maturity (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 at all
times be the Applicable Eurodollar Margin plus the relevant Eurodollar Rate.

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

         (d) Interest shall accrue from and including the date of any Borrowing
to but excluding the date of any repayment thereof and shall be payable (i) in
respect of each Base Rate Loan, quarterly in arrears on each Quarterly Payment
Date, (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) 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 Revolving Loan, at
maturity (whether by acceleration or otherwise) and, after such maturity, on
demand.

         (e) All computations of interest hereunder shall be made in accordance 
with Section 11.07(b).

         (f) The Agent, upon determining the interest rate for any Borrowing of
Eurodollar Loans for any Interest Period, shall promptly notify the Borrower and
the Banks thereof.

         1.09 Interest Periods. At the time the Borrower gives a Notice of
              ----------------
Borrowing or Notice of Conversion in respect of the making of, or conversion
into, a Borrowing of Eurodollar Loans (in the case of the initial Interest
Period applicable thereto) or prior to 12:00 Noon (New York time) on the third
Business Day prior to the expiration of an Interest Period applicable to a
Borrowing of Eurodollar Loans, it shall have the right to elect by giving the
Agent written notice (or telephonic notice promptly confirmed in writing) of the
Interest Period applicable to such Borrowing, which Interest Period shall, at
the option of the Borrower, be a one-, two-, three- or six-month period.
Notwithstanding anything to the contrary contained above:

                                       -4-
<PAGE>
 
                  (i) all Eurodollar Loans comprising a Borrowing shall 
         have the same Interest Period;

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

                  (iii) if any Interest Period 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, that if any Interest Period
                                       --------
         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 may be elected if it 
         would extend beyond the Final Maturity Date; and

                  (vi) no Interest Period may be elected at any time when a 
         payment Default, or an Event of Default, is then in existence.

If upon the expiration of any Interest Period, the Borrower has failed to elect,
or is not permitted to elect by virtue of the application of clause (v) or (vi)
above, a new Interest Period to be applicable to the respective Borrowing of
Eurodollar Loans as provided above, the Borrower shall be deemed to have elected
to convert such Borrowing into a Borrowing of 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 (x) in the
              --------------------------------
case of clause (i) below, the Agent or (y) in the case of clauses (ii) and (iii)
below, any Bank, shall have determined (which determination shall, absent
manifest error, be final and conclusive and binding upon all parties hereto):

                  (i) on any date for determining the Eurodollar Rate for any
         Interest Period, 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 Eurodollar 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 Loans (other than any increased cost or
         reduction in the amount received or receivable resulting from the
         imposition of or a change in the rate of net income taxes or similar
         charges) because of (x) any change since the date of this Agreement in
         any applicable

                                       -5-
<PAGE>
 
         law, governmental rule, regulation, guideline, order 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, guideline, order or request (such as,
         for example, but not limited to 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
         Eurodollar Rate) and/or (y) other circumstances affecting such Bank,
         the interbank Eurodollar market or the position of such Bank in such
         market; or

                  (iii) at any time since the date of this Agreement, that the
         making or continuance of any Eurodollar Loan has become unlawful by
         compliance by such Bank in good faith with any law, governmental rule,
         regulation, guideline or order (or would conflict with any such
         governmental rule, regulation, guideline or order not having the force
         of law but with which such Bank customarily complies even though the
         failure to comply therewith would not be unlawful), or has become
         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 (x) on such date and (y) as promptly as practicable (and in any
event within five Business Days) after the date on which such event no longer
exists give notice (by telephone confirmed in writing) to the Borrower and
(except in the case of clause (i)) 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 shall be
deemed rescinded by the Borrower, (y) in the case of clause (ii) above, the
Borrower agrees to pay to such Bank, upon written demand therefor (accompanied
by the written notice referred to below), 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 the basis for the calculation thereof,
submitted to the Borrower by such Bank shall, absent manifest error, be final
and conclusive and binding upon all 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 pursuant to Section 1.10(a)(iii) the
Borrower shall) either (i) if the affected Eurodollar Loan is then being made
pursuant to a Borrowing, cancel said Borrowing by giving the Agent telephonic
notice (confirmed promptly in writing) thereof on the same date that the
Borrower was notified by a Bank pursuant to Section 1.10(a)(ii) or (iii)), or
(ii) if the affected Eurodollar Loan is then outstanding, upon at least three
Business Days' notice to the Agent, require the affected Bank to convert each
such Eurodollar Loan into a Base Rate Loan

                                       -6-
<PAGE>
 
(which conversion, in the case of the circumstances described in Section
1.10(a)(iii), shall occur no later than the last day of the Interest Period then
applicable to such Eurodollar Loan (or such earlier date as shall be required by
applicable law)); 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 the National Association of Insurance Commissioners
("NAIC") or 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 the NAIC
or 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 Revolving Loan Commitment or
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 last sentence of this clause (c), the Borrower agrees to pay
to such Bank such additional amount or amounts as will compensate such Bank or
such other corporation for such reduction. Each Bank, upon determining in good
faith that any additional amounts will be payable pursuant to this Section
1.10(c), will give prompt written notice thereof to the Borrower, 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.

         1.11 Compensation. The Borrower agrees to compensate each Bank,
              ------------
promptly upon its written request (which request shall set forth the basis for
requesting such compensation and shall be made through the Agent), for all
reasonable 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
but excluding loss of anticipated profit with respect to any Revolving Loans)
which such Bank may sustain: (i) if for any reason (other than a default by such
Bank or the Agent) a Borrowing of Eurodollar Loans does not occur on a date
specified therefor in a Notice of Borrowing or Notice of Conversion (whether or
not withdrawn by the Borrower or deemed withdrawn pursuant to Section 1.10(a));
(ii) if any repayment (including any repayment made pursuant to Section 3.01 or
3.02 or as a result of an acceleration of the Revolving Loans pursuant to
Section 8) or conversion of any Eurodollar Loans occurs on a date which is not
the last day of an Interest Period applicable thereto; (iii) if any prepayment
of any Eurodollar Loans is not made on any date specified in a notice of
prepayment given by the Borrower; or (iv) as a consequence of (x) any other
default by the Borrower to repay its Eurodollar Loans when required by the terms
of this Agreement or (y) an election made pursuant to Section 1.10(b).
Calculation of all amounts payable to a Bank under this Section 1.11 shall be
made as though that Bank had actually funded its relevant Eurodollar Loan

                                       -7-

<PAGE>
 
through the purchase of a Eurodollar deposit bearing interest at the Eurodollar
Rate in an amount equal to the amount of that Eurodollar Loan, having a maturity
comparable to the relevant Interest Period and through the transfer of such
Eurodollar deposit from an offshore office of that Bank to a domestic office of
that Bank in the United States of America; provided, however, that each Bank may
                                           --------  -------
fund each of its Eurodollar Loans in any manner it sees fit and the foregoing
assumption shall be utilized only for the calculation of amounts payable under
this Section 1.11. It is further understood and agreed that if any repayment of
Eurodollar Loans pursuant to Section 3.01 or any conversion of Eurodollar Loans
pursuant to Section 1.06 in either case occurs on a date which is not the last
day of an Interest Period applicable thereto, such repayment or conversion shall
be accompanied by any amounts owing to any Bank pursuant to this Section 1.11.

         1.12 Change of Lending Office. Each Bank agrees that, upon the
              ------------------------
occurrence of any event giving rise to the operation of Section 1.10(a)(ii) or
(iii), 1.10(c) or 3.04 with respect to such Bank, it will, if requested by the
Borrower, use reasonable efforts (subject to overall policy considerations of
such Bank) to designate another lending office for any Revolving Loans affected
by such event; provided, that such designation is made on such terms that, in
               --------
the sole judgment of such Bank, such Bank and its lending office suffer no
economic, legal or regulatory disadvantage, with the object of avoiding the
consequences of the event giving rise to the operation of any such Section.
Nothing in this Section 1.12 shall affect or postpone any of the obligations of
the Borrower or the right of any Bank provided in Section 1.10 or 3.04.

         1.13 Replacement of Banks. (x) If any Bank becomes a Defaulting Bank,
              --------------------
(y) upon the occurrence of any event giving rise to the operation of Section
1.10(a)(ii) or (iii), Section 1.10(c) or Section 3.04 with respect to any Bank
which results in such Bank charging to the Borrower increased costs in excess of
those being generally charged by the other Banks or (z) in the case of a refusal
by a Bank to consent to a proposed change, waiver, discharge or termination with
respect to this Agreement which has been approved by the Required Banks as
provided in Section 11.12(b), the Borrower shall have the right, if no payment
Default, or Event of Default, then exists, to replace such Bank (the "Replaced
Bank") with one or more other Eligible Transferee or Transferees, none of whom
shall constitute a Defaulting Bank at the time of such replacement
(collectively, the "Replacement Bank") reasonably acceptable to the Agent,
provided that (i) at the time of any replacement pursuant to this Section 1.13,
- --------
the Replacement Bank shall enter into one or more Assignment and Assumption
Agreements pursuant to Section 11.04(b) (and with all fees payable pursuant to
said Section 11.04(b) to be paid by the Replacement Bank) pursuant to which the
Replacement Bank shall acquire all of the Revolving Loan Commitment and
outstanding Revolving Loans of the Replaced Bank and, in connection therewith,
shall pay to 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 Revolving Loans of the Replaced Bank and (B) an amount equal to all
accrued, but theretofore unpaid, Fees owing to the Replaced Bank pursuant to
Section 2.01 and (ii) all obligations (including, without limitation, all such
amounts, if any, due and owing under Section 1.11) of the Borrower due and 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 to such Replaced Bank
concurrently with such replacement. Upon the execution of the respective
Assignment and

                                       -8-
<PAGE>
 
Assumption Agreements, 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 6.13 and, if so requested by the Replacement Bank, delivery to the
Replacement Bank of the appropriate Revolving Note or Revolving Notes executed
by the Borrower, (x) the Replacement Bank shall become a Bank hereunder and the
Replaced Bank shall cease to constitute a Bank hereunder, except with respect to
indemnification provisions under this Agreement, which shall survive as to such
Replaced Bank and (y) Annex I shall be deemed modified to reflect the changed
Revolving Loan Commitments (and/or outstanding Revolving Loans, as the case may
be) resulting from the assignment from the Replaced Bank to the Replacement
Bank.

         SECTION 2.  Fees; Commitments.
                     -----------------
         2.01 Fees. (a) The Borrower shall pay to the Agent for distribution to
              ----
each Bank a commitment fee (the "Commitment Fee") for the period from the
Effective Date to but not including the date the Total Revolving Loan Commitment
has been terminated, computed at a rate for each day equal to 1/2 of 1% on the
daily Unutilized Revolving Loan Commitment of such Bank. Accrued Commitment Fees
shall be due and payable in arrears on each Quarterly Payment Date and the date
upon which the Total Revolving Loan Commitment is terminated.

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

         (c) All computations of Fees shall be made in accordance with 
Section 11.07(b).

         2.02 Voluntary Termination or Reduction of Total Unutilized Revolving
              ----------------------------------------------------------------
Loan Commitment. (a) Upon at least two 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
partially reduce the Total Unutilized Revolving Loan Commitment; provided that
                                                                 --------
(x) any such termination or partial reduction shall apply to proportionately and
permanently reduce the Revolving Loan Commitment of each of the Banks and (y)
any partial reduction pursuant to this Section 2.02(a) shall be in the amount of
at least $100,000.

         (b) In the event of certain refusals by a Bank 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
11.12(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 the Revolving Loan
Commitment of such Bank, so long as all Revolving Loans, together with accrued
and unpaid interest, Fees and all other amounts, due and owing to such Bank are
repaid concurrently with the effectiveness of such termination pursuant to
Section 3.01(b) (at which time Annex I shall be deemed modified to reflect such
changed Revolving Loan Commitments), and at such time, such Bank shall no longer
constitute a "Bank" for purposes of this Agreement, except with respect to
indemnifications under this Agreement (including,

                                       -9-
<PAGE>
 
without limitation, Sections 1.10, 1.11, 3.04, 11.01 and 11.06), which shall
survive as to such repaid Bank.

         2.03 Mandatory Reduction or Termination of Revolving Loan Commitments,
              ---------------------------------------------------------------- 
etc. (a) The Total Revolving Loan Commitment shall terminate in its entirety on
- ---
January 31, 1997 unless the Initial Borrowing Date has occurred on or before
such date.

         (b) The Total Revolving Loan Commitment (and the Revolving Loan
Commitment of each Bank) shall terminate on the earlier of (x) the date on which
a Change of Control Event occurs and (y) the Final Maturity Date.

         (c) Each reduction or termination of the Total Revolving Loan
Commitment pursuant to this Section 2.03 shall apply proportionately to the
Revolving Loan Commitment of each Bank.

         SECTION 3. Payments.
                    --------
         3.01 Voluntary Prepayments. (a) The Borrower shall have the right to
              ---------------------
prepay the Revolving Loans made to it, in whole or in part, without premium or
penalty, except as otherwise provided in this Agreement, from time to time on
the following terms and conditions: (i) the Borrower shall give the Agent at its
Notice Office written notice (or telephonic notice promptly confirmed in
writing) of its intent to prepay such Revolving Loans, the amount of such
prepayment and (in the case of Eurodollar Loans) the specific Borrowing(s)
pursuant to which made, which notice shall be given by the Borrower prior to
11:00 A.M. (New York time) (x) on or prior to the date of such prepayment in the
case of Base Rate Loans and (y) at least three Business Days prior to the date
of such prepayment in the case of Eurodollar Loans, which notice shall promptly
be transmitted by the Agent to each of the Banks; (ii) each prepayment shall be
in an aggregate principal amount of (A) at least $100,000 in the case of
Eurodollar Loans and (B) at least $25,000 in the case of Base Rate Loans;
provided, that no partial prepayment of Eurodollar Loans made pursuant to a
- --------
Borrowing shall reduce the aggregate principal amount of the Eurodollar Loans
outstanding pursuant to such Borrowing to an amount less than the Minimum
Borrowing Amount applicable thereto; and (iii) each prepayment in respect of any
Revolving Loans made pursuant to a Borrowing shall be applied pro rata among
such Revolving Loans; provided, that at the Borrower's election in connection
with any prepayment of Revolving Loans pursuant to this Section 3.01, such
prepayment shall not be applied to any Revolving Loans of a Defaulting Bank at
any time when the aggregate amount of Revolving Loans of any Non-Defaulting Bank
exceeds such Non-Defaulting Bank's Percentage of all Revolving Loans then
outstanding.

         (b) In the event of certain refusals by a Bank 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
11.12(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 repay all Revolving Loans, together
with accrued and unpaid interest, Fees and all other amounts due and owing to

Loan

                                      -10-
<PAGE>
 
Commitment of such Bank is terminated concurrently with such repayment pursuant
to Section 2.02(b) (at which time Annex I shall be deemed modified to reflect
the changed Revolving Loan Commitments) and (B) the consents required by Section
11.12(b) in connection with the repayment pursuant to this clause (b) shall have
been obtained.

         3.02  Mandatory Prepayments.
               ---------------------
         (A)   Requirements:
               -------------
               (a) If on any date the aggregate outstanding principal amount
         of Revolving Loans exceeds the Total Revolving Loan Commitment as then
         in effect, the Borrower shall repay on such date the principal of
         Revolving Loans in an aggregate amount equal to such excess.

               (b) Notwithstanding anything to the contrary contained in this
         Agreement, all outstanding Revolving Loans shall be repaid in full on
         the earlier of (x) the date on which a Change of Control Event occurs
         and (y) the Final Maturity Date.

         (B) Application: With respect to each repayment of Revolving Loans
             -----------
required by this Section 3.02, the Borrower may designate the Types of Revolving
Loans which are to be repaid and the specific Borrowing(s) pursuant to which
made; provided, that (i) Eurodollar Loans may be designated for repayment
      --------
pursuant to this Section 3.02 only on the last day of an Interest Period
applicable thereto unless all Eurodollar Loans with Interest Periods ending on
such date of required prepayment and all Base Rate Loans have been paid in full;
(ii) if any repayment of Eurodollar Loans made pursuant to a single Borrowing
shall reduce the outstanding Revolving Loans made pursuant to such Borrowing to
an amount less than the Minimum Borrowing Amount, such Borrowing shall be
immediately converted into Base Rate Loans; and (iii) each repayment of any
Revolving Loans made pursuant to a Borrowing shall be applied pro rata among
                                                              --- ----
such Revolving Loans; provided, that no repayment pursuant to Section 3.02(A)(a)
                      --------
shall be applied to any Revolving Loans of a Defaulting Bank at any time when
the aggregate amount of the Revolving Loans of any Non-Defaulting Bank exceeds
such Non-Defaulting Bank's Percentage of Revolving Loans then outstanding. In
the absence of a designation by the Borrower as described in the preceding
sentence, the Agent shall, subject to the above, make such designation in its
sole discretion with a view, but no obligation, to minimize breakage costs owing
under Section 1.11.

         3.03 Method and Place of Payment. Except as otherwise specifically
              ---------------------------
provided herein, all payments under this Agreement shall be made to the Agent
for the ratable account of the Banks entitled thereto, not later than 12:00 Noon
(New York time) on the date when due and shall be made in immediately available
funds and in U.S. Dollars at the Payment Office, it being understood that
written, telex or facsimile transmission notice by the Borrower to the Agent to
make a payment from the funds in the Borrower's account at the Payment Office
shall constitute the making of such payment to the extent of such funds held in
such account. Any payments under this Agreement which are made later than 12:00
Noon (New York time) shall be deemed to have been made on the next succeeding
Business Day. Whenever any payment to be made hereunder 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

                                      -11-
<PAGE>
 
Day and, with respect to payments of principal, interest shall be payable during
such extension at the applicable rate in effect immediately prior to such
extension.

         3.04 Net Payments. (a) All payments made by the Borrower hereunder or
              ------------
under any Revolving Note will be made without setoff, counterclaim or other
defense. Except as provided in Section 3.04(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 or net profits of a Bank pursuant to
the laws of the jurisdiction in which it is organized or the jurisdiction in
which the principal office or applicable lending office of such Bank is located
or any subdivision thereof or therein) and all interest, penalties or similar
liabilities with respect thereto (all such non-excluded taxes, levies, imposts,
duties, fees, assessments or other charges being referred to collectively as
"Taxes"). If any Taxes are so levied or imposed, the Borrower agrees to pay the
full amount of such Taxes, and such additional amounts as may be necessary so
that every payment of all amounts due under this Agreement or under any
Revolving 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 Revolving Note.
If any amounts are payable in respect of Taxes pursuant to the preceding
sentence, the Borrower agrees to reimburse each Bank, upon the written request
of such Bank, for taxes imposed on or measured by the net income or net profits
of such Bank pursuant to the laws of the jurisdiction in which the principal
office or applicable lending office of such Bank is located or under the laws of
any political subdivision or taxing authority of any such jurisdiction in which
the principal office or applicable lending office of such Bank is located and
for any withholding of taxes as such Bank shall determine are payable by, or
withheld from, 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 will
furnish to the Agent within 45 days after the date the payment of any Taxes is
due pursuant to applicable law certified copies of tax receipts evidencing such
payment by the Borrower. The Borrower agrees 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.

         (b) Each Bank 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 Bank that
is an assignee or transferee of an interest under this Agreement pursuant to
Section 1.13 or 11.04 (unless the respective Bank was already a Bank hereunder
immediately prior to such assignment or transfer), on the date of such
assignment or transfer to such Bank, (i) two accurate and complete original
signed copies of Internal Revenue Service Form 4224 or 1001 (or successor forms)
certifying to such Bank's entitlement to a complete exemption from United States
withholding tax with respect to payments to be made under this Agreement and
under any Revolving Note, or (ii) if the Bank is not a "bank" within the meaning
of Section 881(c)(3)(A) of the Code and cannot deliver either Internal Revenue
Service Form 1001 or 4224 pursuant to clause (i) above, (x) a certificate
substantially in the form of Exhibit C (any such certificate, a "Section

Existing Indebtedness and obligations arising under or out of the Stockholders'

assertion against the Borrower or any of its Consolidated Entities of any such
liability or obligation which, in the case of clause (i) or (ii) either
individually or in the aggregate, is or would be reasonably likely to have, a
Material Adverse Effect.

         (d)    The Projections are based on good faith estimates and
assumptions made by the management of the Borrower, and on the Initial Borrowing

                                      -25-
<PAGE>
 
the Additional Security Documents may be subject to Permitted Liens relating

         5.12   Transaction. At the time of consummation thereof, the
                -----------

registrations with, and all other actions in respect of, all governmental
agencies, authorities or instrumentalities required in order to make or
consummate the Transaction have been obtained, given, filed or taken or waived
and are or will be in full force and effect (or effective judicial relief with
respect thereto has been obtained), except where the failure to obtain, give,
file, or take would not reasonably be expected to have a Material Adverse
Effect. Additionally, there does not exist any judgment, order or injunction
prohibiting or imposing material adverse conditions upon the Transaction or the
performance by the Borrower and its Consolidated Entities of their obligations

made with respect to a Plan have been timely made; neither the Borrower nor any
Consolidated Entity nor any ERISA Affiliate has incurred any material liability
to or on account of a Plan pursuant to Section 409, 502(i), 502(l), 515, 4062,
4063, 4064, 4069, 4201, 4204 or 4212 of ERISA or Section 401(a)(29), 4971, 4975
or 4980 of the Code or reasonably expects to incur any material liability
(including any indirect, contingent or secondary liability) under any of the
foregoing Sections with respect to any Plan (other than liabilities of any ERISA
Affiliate which could not, by operation of law or otherwise, become a liability
of the Borrower or any of its Consolidated Entities); no proceedings have been
instituted to terminate, or to appoint a trustee to administer, any Plan; no
condition exists which presents a material risk to the Borrower or any
Consolidated Entity or any ERISA Affiliate of incurring a liability to or on
account of a Plan pursuant to the foregoing provisions of ERISA and the Code;
using actuarial assumptions and computation methods consistent with subpart 1 of
subtitle E of Title IV of ERISA, the aggregate liabilities of the Borrower and
its Consolidated Entities and its ERISA Affiliates to all Plans which are
multiemployer plans (as defined in Section 4001(a)(3) of ERISA) in the event of
a complete withdrawal therefrom, as of the close of the most recent fiscal year
of each such Plan ended prior to the date of the most recent incurrence of
Revolving Loans, would not result in a Material Adverse Effect; no lien imposed
under the Code or ERISA on the assets of the Borrower or any Consolidated Entity
or any ERISA Affiliate exists or is likely to arise on account of any Plan; and
the Borrower and its Consolidated Entities do not maintain or contribute to any
employee welfare benefit plan (as defined in Section 3(1) of ERISA) which
provides benefits to retired employees or

                                      -26-
<PAGE>
 
other former employees (other than as required by Section 601 of ERISA) or any
employee pension benefit plan (as defined in Section 3(2) of ERISA) the
obligations with respect to which could reasonably be expected to have a
Material Adverse Effect.

forth, as of the Initial Borrowing Date, the percentage ownership (direct and
indirect) of the Borrower, in each class of the capital stock of each of its
Subsidiaries and also identifies the direct owner thereof. All outstanding
shares of capital stock or other equity interests of each Subsidiary of the
Borrower and each Affiliated Business have been duly and validly issued, are
fully paid and nonassessable and have been issued free of preemptive rights.
Neither any Subsidiary of the Borrower nor any Affiliated Business has
outstanding any securities convertible into or exchangeable for its capital
stock or other equity interests or outstanding any right to subscribe for or to
purchase, or any options or warrants for the purchase of, or any agreement
providing for the issuance (contingent or otherwise) of or any calls,
commitments or claims of any character relating to, its capital stock or other
equity interests or any stock appreciation or similar rights.

         5.16 Intellectual Property. The Borrower and each of its Consolidated
              ---------------------
Entities owns or holds a valid license to use all the material patents,
trademarks, permits, service marks, trade names, technology, know-how and
formulas or other rights with respect to the foregoing, free from restrictions
that are materially adverse to the use thereof, that are used in the operation
of the business of the Borrower and each of its Consolidated Entities as
presently conducted.

         5.17 Compliance with Statutes, Permits, etc. (a) The Borrower and each
              --------------------------------------
of its Consolidated Entities, to the knowledge of the Borrower, is in compliance

(including compliance with all applicable Environmental Laws with respect to any
Real Property or governing its business and the requirements of any permits
issued under such Environmental Laws with respect to any such Real Property or
the operations of the Borrower or any of its Consolidated Entities), except such

Material Adverse Effect.

         (b)  The Borrower and each of the Consolidated Entities and all
physicians employed by such Consolidated Entities have all licenses, permits,
franchises, approvals, authorizations, consents or orders of, or filings with

<PAGE>
 
foreign or other governmental agency, instrumentality, commission, authority,
board or any other Person, necessary or desirable to conduct their business as
now being conducted except where the failure to have any such Permit does not
have a Material Adverse Effect. All Permits of the Borrower and the Consolidated
Entities and all physicians employed by the Consolidated Entities are valid and
in full force and effect except where the failure to have any such Permit does
not have a Material Adverse Effect.

         (c)  Neither the Borrower nor any of the Consolidated Entities, nor any
other persons or entities providing professional services for the Consolidated
Entities, have engaged in any activities which are prohibited under 42 U.S.C.
ss. 1320a-7b, or the regulations promulgated thereunder pursuant to such
statutes, or related state or local statutes or regulations, or which are

to fraudulently secure such benefit of payment; and (iv) knowingly and willfully
soliciting or receiving any remuneration (including any kickback, bribe or

              ---------------------
Consolidated Entities have complied with, and on the date of each Revolving Loan
are in compliance with, all applicable Environmental Laws and the requirements
of any permits issued under such Environmental Laws. There are no pending or, to
the best knowledge of the Borrower, past or threatened Environmental Claims
against the Borrower or any of its Consolidated Entities or any Real Property
owned or operated by the Borrower or any of its Consolidated Entities that
individually or in the aggregate would reasonably be expected to have a Material
Adverse Effect. There are no facts, circumstances, conditions or occurrences on
any Real Property owned or operated by the Borrower or any of its Consolidated
Entities or, to the best knowledge of the Borrower, on any property adjoining or
in the vicinity of any such Real Property that would reasonably be expected (i)
to form the basis of an Environmental Claim against the Borrower or any of its
Consolidated Entities or any such Real Property that individually or in the
aggregate would reasonably be expected to have a Material Adverse Effect or (ii)
to cause any such Real Property to be subject to any restrictions on the
ownership, occupancy, use or transferability of such Real Property by the
Borrower or any of its Consolidated Entities under any applicable Environmental
Law.

         (b)  Hazardous Materials have not at any time been generated, used,
treated or stored on, or transported to or from, any Real Property owned or

<PAGE>
 
violated or would reasonably be expected to violate any Environmental Law.
Hazardous Materials have not at any time been Released on or from any Real
Property owned or operated by the Borrower or any of its Consolidated Entities.
There are not now any underground storage tanks located on any Real Property
owned or operated by the Borrower or any of its Consolidated Entities.

         (c)  Notwithstanding anything to the contrary in this Section 5.18, the
representations made in this Section 5.18 shall only be untrue if the aggregate
effect of all restrictions, failures, noncompliance, Environmental Claims,
Releases and presence of underground storage tanks, in each case of the types
described above, would reasonably be expected to have a Material Adverse Effect.

         5.19 Properties. All Real Property owned or leased by the Borrower or
              ----------
any of its Consolidated Entities as of the Initial Borrowing Date and after

         SECTION 10.  The Agent.
                      ----------

         10.01 Appointment. Each Bank hereby irrevocably designates and appoints
               -----------
BTCo as Agent of such Bank (such term to include for purposes of this Section
10, BTCo acting as Collateral Agent) to act as specified herein and in the other
Credit Documents, and each such Bank hereby irrevocably authorizes BTCo as the
Agent to take such action on its behalf under the provisions of this Agreement
and the other Credit Documents and to exercise such powers and perform such
duties as are expressly delegated to the Agent by the terms of this Agreement
and the other Credit Documents, together with such other powers as are
reasonably incidental thereto. The Agent agrees to act as such upon the express
conditions contained in this Section 10. Notwithstanding any provision to the
contrary elsewhere in this Agreement or in any other Credit Document, the Agent
shall not have any duties or responsibilities, except those expressly set forth
herein or in the other Credit Documents, or any fiduciary relationship with any
Bank, and no implied covenants, functions, responsibilities, duties, obligations
or liabilities shall be read into this Agreement or otherwise exist against the
Agent. The provisions of this Section 10 are solely for the benefit of the Agent
and the Banks, and neither the Borrower nor any of its Consolidated Entities
shall have any rights as a third party beneficiary of any of the provisions
hereof. In performing its

                                      -63-
<PAGE>
 
functions and duties under this Agreement, the Agent shall act solely as agent
of the Banks and the Agent does not assume and shall not be deemed to have
assumed any obligation or relationship of agency or trust with or for the
Borrower or any of its Consolidated Entities.

         10.02 Delegation of Duties. The Agent may execute any of its duties
               --------------------
under this Agreement or any other Credit Document by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by it with
reasonable care except to the extent otherwise required by Section 10.03.

         10.03 Exculpatory Provisions. Neither the Agent nor any of its
               ----------------------
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(i) liable for any action lawfully taken or omitted to be taken by it or such
Person in its capacity as Agent under or in connection with this Agreement or
the other Credit Documents (except for its or such Person's own gross negligence
or willful misconduct) or (ii) responsible in any manner to any of the Banks for
any recitals, statements, representations or warranties made by the Borrower,
any of its Consolidated Entities or any of their respective officers contained
in this Agreement or the other Credit Documents, any other Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection with, this Agreement or any
other Document or for any failure of the Borrower or any of its Consolidated
Entities or any of their respective officers to perform its obligations
hereunder or thereunder. The Agent shall not be under any obligation to any Bank
to ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or the other
Documents, or to inspect the properties, books or records of the Borrower or any
of its Consolidated Entities. The Agent shall not be responsible to any Bank for
the effectiveness, genuineness, validity, enforceability, collectability or
sufficiency of this Agreement or any other Document or for any representations,
warranties, recitals or statements made herein or therein or made in any written
or oral statement or in any financial or other statements, instruments, reports,
certificates or any other documents in connection herewith or therewith
furnished or made by the Agent to the Banks or by or on behalf of the Borrower
or any of its Consolidated Entities to the Agent or any Bank or be required to
ascertain or inquire as to the performance or observance of any of the terms,
conditions, provisions, covenants or agreements contained herein or therein or
as to the use of the proceeds of the Revolving Loans or of the existence or
possible existence of any Default or Event of Default.

         10.04 Reliance by Agent. The Agent shall be entitled to rely, and shall
               -----------------
be fully protected in relying, upon any note, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, facsimile, telex
or teletype message, statement, order or other document or conversation believed
by it to be genuine and correct and to have been signed, sent or made by the
proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Borrower or any of its
Subsidiaries), independent accountants and other experts selected by the Agent.
The Agent shall be fully justified in failing or refusing to take any action
under this Agreement or any other Credit Document unless it shall first receive
such advice or concurrence of the Required Banks as it deems appropriate or it
shall first be indemnified to its satisfaction by the Banks against any and all
liability and expense which may be incurred by it by reason of taking or
continuing

                                      -64-
<PAGE>
 
to take any such action. The Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement and the other Credit
Documents in accordance with a request of the Required Banks (or all of the
Banks, to the extent required by this Agreement), and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the
Banks.

         10.05 Notice of Default. The Agent shall not be deemed to have
               -----------------
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Agent has actually received notice from a Bank or the
Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default." In the event that
the Agent receives such a notice, the Agent shall give prompt notice thereof to
the Banks. The Agent shall take such action with respect to such Default or
Event of Default as shall be reasonably directed by the Required Banks;
provided, that, unless and until the Agent shall have received such directions,
- --------
the Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interests of the Banks.

         10.06 Non-Reliance on Agent and Other Banks. Each Bank expressly
               -------------------------------------
acknowledges that neither the Agent nor any of its respective officers,
directors, employees, agents, attorneys-in-fact or affiliates have made any
representations or warranties to it and that no act by the Agent hereinafter
taken, including any review of the affairs of the Borrower or any of its
Consolidated Entities, shall be deemed to constitute any representation or
warranty by the Agent to any Bank. Each Bank represents to the Agent that it
has, independently and without reliance upon the Agent or any other Bank, and
based on such documents and information as it has deemed appropriate, made its
own appraisal of and investigation into the business, assets, operations,
property, financial and other condition, prospects and creditworthiness of the
Borrower and its Consolidated Entities and made its own decision to make its
Revolving Loans hereunder and enter into this Agreement. Each Bank also
represents that it will, independently and without reliance upon the Agent or
any other Bank, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement, and to make
such investigation as it deems necessary to inform itself as to the business,
assets, operations, property, financial and other condition, prospects and
creditworthiness of the Borrower and its Consolidated Entities. The Agent shall
not have any duty or responsibility to provide any Bank with any credit or other
information concerning the business, operations, assets, property, financial and
other condition, prospects or creditworthiness of the Borrower or any of its
Consolidated Entities which may come into the possession of the Agent or any of
its officers, directors, employees, agents, attorneys-in-fact or affiliates.

         10.07 Indemnification. The Banks agree to indemnify the Agent in its
               ---------------
capacity as such ratably according to their respective "percentages" as used in
determining the Required Banks at such time or, if the Total Revolving Loan
Commitment has terminated and all Revolving Loans have been repaid in full, as
determined immediately prior to such termination and repayment (with such
"percentages" to be determined as if there are no Defaulting Banks), from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, reasonable expenses or disbursements of any
kind

                                      -65-
<PAGE>
 
whatsoever which may at any time (including, without limitation, at any time
following the payment of the Obligations) be imposed on, incurred by or asserted
against the Agent in its capacity as such in any way relating to or arising out
of this Agreement or any other Credit Document, or any documents contemplated by
or referred to herein or the transactions contemplated hereby or any action
taken or omitted to be taken by the Agent under or in connection with any of the
foregoing, but only to the extent that any of the fore- going is not paid by the
Borrower or any of its Consolidated Entities; provided, that no Bank shall be
                                              --------
liable to the Agent for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting primarily from the gross negligence or
willful misconduct of the Agent. If any indemnity furnished to the Agent for any
purpose shall, in the opinion of the Agent be insufficient or become impaired
(other than as a result of the gross negligence or willful misconduct of the
Agent), the Agent may call for additional indemnity and cease, or not commence,
to do the acts indemnified against until such additional indemnity is furnished.
The agreements in this Section 10.07 shall survive the payment of all
Obligations.

         10.08 Agent in its Individual Capacity. The Agent and its affiliates
               --------------------------------
may make loans to, accept deposits from and generally engage in any kind of
business with the Borrower and its Subsidiaries as though the Agent were not the
Agent hereunder. With respect to the Revolving Loans made by it and all
Obligations owing to it, the Agent shall have the same rights and powers under
this Agreement as any Bank and may exercise the same as though it were not the
Agent and the terms "Bank" and "Banks" shall include the Agent in its individual
capacity. The Agent and/or its affiliates may own stock of the Borrower or any
Subsidiary of the Borrower and may accept deposits from, lend money to, and
generally engage in any kind of banking, trust or other business with the
Borrower or any Affiliate of the Borrower as if it were not performing the
duties specified herein, and may accept fees and other consideration from any
Credit Party for services in connection with this Agreement and otherwise
without having to account for the same to the Banks.

         10.09 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 or
entity who, at the time of making such request or giving such authority or
consent, is the holder of any Revolving Note shall be conclusive and binding on
any subsequent holder, transferee, assignee or indorsee, as the case may be, of
such Revolving Note or of any Revolving Note or Revolving Notes issued in
exchange therefor.

         10.10 Resignation of the Agent; Successor Agent. The Agent may resign
               -----------------------------------------
as the Agent upon 20 days' notice to the Banks and, unless a Default of the type
referred to in Section 8.05 has occurred and is continuing, to the Borrower.
Upon the resignation of the Agent, the Required Banks shall appoint from among
the Banks a successor Agent which is a bank or a trust company for the Banks
subject, to the extent that no payment Default or Event of Default has occurred
and is then continuing, to prior approval by the Borrower (such approval not to
be unreasonably withheld or delayed), whereupon such successor agent shall
succeed to the rights, powers and duties of the Agent, and the term "Agent"
shall include such successor agent effective upon its appointment, and the
resigning Agent's rights,

                                      -66-
<PAGE>
 
powers and duties as the Agent shall be terminated, without any other or further
act or deed on the part of such former Agent or any of the parties to this
Agreement. If a successor Agent shall not have been so appointed within such 20
day period after the date such notice of resignation was given by the Agent, the
Agent's resignation shall become effective and the Banks shall thereafter
perform all duties of the Agent hereunder and/or under any other Credit
Documents until such time, if any, as the Required Banks appoint a successor
Agent as provided above. After the resignation of the Agent hereunder, the
provisions of this Section 10 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Agent under this Agreement.

         SECTION 11. Miscellaneous.
                     --------------
         11.01 Payment of Expenses, etc. The Borrower hereby agrees to: (i)
               ------------------------

reasonable out-of-pocket costs and expenses of the Agent (including, without
limitation, the reasonable fees and disbursements of White & Case) in connection

Documents and the documents and instruments referred to therein and any
amendment, waiver or consent relating thereto and in connection with the Agent's

of the Banks thereunder (including, without limitation, the reasonable fees and
disbursements of counsel (including in-house counsel) for the Agent and for each
of the Banks); (iii) pay and hold each of the Banks harmless from and against
any and all present and future stamp and other similar taxes with respect to the
foregoing matters and save each of the Banks harmless from and against any and
all liabilities with respect to or resulting from any delay or omission (other
than to the extent attributable to such Bank) to pay such taxes; and (iv)
indemnify the Agent, the Collateral Agent and each Bank, its officers,
directors, trustees, employees, representatives and agents from and hold each of
them harmless against any and all losses, liabilities, claims, damages or
expenses incurred by any of them as a result of, or arising out of, or in any
way related to, or by reason of, (a) any investigation, litigation or other
proceeding (whether or not the Agent, the Collateral Agent or any Bank is a
party thereto and whether or not any such investigation, litigation or other
proceeding is between or among the Agent, the Collateral Agent, any Bank, any
Credit Party or any third Person or otherwise) related to the entering into
and/or performance of this Agreement or any other Document or the use of the
proceeds of any Revolving Loans hereunder or the Transaction or the consummation
of any other transactions contemplated in any Document (but excluding any such
losses, liabilities, claims, damages or expenses to the extent incurred by
reason of the gross negligence or willful misconduct of the Person to be
indemnified), or (b) the actual or alleged presence of Hazardous Materials in
the air, surface water or groundwater or on the surface or subsurface of any
Real Property or any Environmental Claim, in each case, including, without
limitation, the reasonable fees and disbursements of counsel and independent
consultants incurred in connection with any such investigation, litigation or
other proceeding.

         11.02 Right of Setoff. In addition to any rights now or hereafter
               ---------------
granted under applicable law or otherwise, and not by way of limitation of any
such rights, upon the occurrence and during the continuance of an Event of
Default, each Bank is hereby authorized at any time or from time to time,
without presentment, demand, protest or other notice of any kind to the Borrower
or any of its Subsidiaries or to any other Person, any such notice being hereby
expressly waived, to set off and to appropriate and apply any and all deposits
(general or special) and any other Indebtedness at any time held or owing by
such Bank (including, without limitation, by branches and agencies of such Bank
wherever located) to or for the credit or the account of the Borrower or any of
its Subsidiaries against and on account of the Obligations of the Borrower or
any of its Subsidiaries to such Bank under this Agreement or under any of the

Obligations of the Borrower or any of its Subsidiaries purchased by such Bank
pursuant to Section 11.06(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 shall be contingent or unmatured.

               -------
notices and other communications provided for hereunder shall be in writing

at the address specified opposite its signature below or in the other relevant
Credit Documents, as the case may be; if to any Bank, at its address specified
for such Bank on Annex II; or, at such other address as shall be designated by
any party in a written notice to the other parties hereto. All such notices and
communications shall be mailed, telegraphed, telexed, telecopied or cabled or
sent by overnight courier, and shall be effective when received.

         11.04 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 all of the Banks and,
provided further, that no Bank may assign or transfer all or any portion of its
- -------- -------
Revolving Loan Commitment and/or its outstanding Revolving Loans except as
provided in Section 11.04(b) and, provided further, that although any Bank may
                                  -------- -------
grant participations in its rights hereunder in accordance with this Section,
such Bank shall remain a "Bank" for all purposes hereunder and the participant
shall not constitute a "Bank" hereunder and, provided further, that no Bank
                                             -------- -------
shall 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 Revolving Loan or Revolving Note 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 amount of the participant's participation 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 Revolving Loan
Commitment shall not constitute a change in the terms of such participation, and
that an increase in any Revolving Loan Commitment or Revolving Loan

                                      -68-
<PAGE>
 
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 the Borrower 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 Revolving 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 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) assign all or a portion of its Revolving Loan
Commitment (and related outstanding Obligations hereunder) to its parent company
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 Banks or (y) assign all, or if less than
all, a portion equal to at least $1,000,000 in the aggregate for the assigning
Bank or assigning Banks, of such Revolving Loan Commitments (and related
outstanding Obligations) 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, provided that (i) at such time Annex I
                                     --------
shall be deemed modified to reflect the Revolving Loan Commitments of such new
Bank and of the existing Banks, (ii) upon surrender of the old Revolving Notes,
new Revolving Notes will be issued, at the Borrower's expense, to such new Bank
and to the assigning Bank, such new Revolving Notes to be in conformity with the
requirements of Section 1.05 (with appropriate modifications) to the extent
needed to reflect the revised Revolving Loan Commitments, (iii) the consent of
the Agent shall be required in connection with any such assignment pursuant to
clause (y) of this Section 11.04(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 or assignee Bank, the payment of a non-
refundable assignment fee of $3,500 and, provided further, that such transfer or
                                         -------- -------
assignment will not be effective until recorded by the Agent on the Register
pursuant to Section 6.13 hereof. To the extent of any assignment pursuant to
this Section 11.04(b), the assigning Bank shall be relieved of its obligations
hereunder with respect to its assigned Revolving Loan Commitment. At the time of
each assignment pursuant to this Section 11.04(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 the Borrower and the Agent the
appropriate Internal Revenue Service Forms (and, if applicable a Section
3.04(b)(ii) Certificate) described in Section 3.04(b). To the extent that an
assignment of all or any portion of a Bank's Revolving Loan Commitment and
related outstanding Obligations pursuant to Section 1.13 or this Section
11.04(b) would, at the time of such assignment, result in increased costs under
Section 1.10 or 1.11 from those being charged by the respective assigning Bank
prior to such assignment, then the Borrower shall not be obligated to pay such
increased costs (although the Borrower shall be obligated to pay any other
increased costs of the type described above resulting from changes after the
date of the respective assignment).

                                      -69-
<PAGE>
 
         (c)   Nothing in this Agreement shall prevent or prohibit any Bank from
pledging its Revolving Loans and Revolving Notes hereunder to a Federal Reserve
Bank in support of borrowings made by such Bank from such Federal Reserve Bank.

         11.05 No Waiver; Remedies Cumulative. No failure or delay on the part
               ------------------------------
of the Agent or any Bank in exercising any right, power or privilege hereunder
or under any other Credit Document and no course of dealing between any Credit
Party and the Agent or any Bank 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 and remedies herein expressly provided are cumulative and not exclusive
of any rights or remedies which the Agent or any Bank 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 the Banks to any other or
further action in any circumstances without notice or demand.

         11.06 Payments Pro Rata. (a) The Agent agrees that promptly after its
               -----------------
receipt of each payment from or on behalf of any Credit Party in respect of any
Obligations of such Credit Party, it shall, except as otherwise provided in this
Agreement, distribute such payment to the Banks (other than any Bank that has
consented in writing to waive its pro rata share of such payment) 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 Revolving Loans 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

               --------
limitation, in Section 1.10, 1.11, 3.04, 10.07 or 11.01, shall survive the

affiliate of such Bank; provided, that the Borrower shall not be responsible for
costs arising under Section 1.10, 1.11 or 3.04 resulting from any such transfer

company in its sole discretion determines that any such party should have access
to such information) any information with respect to the Borrower or any of its

                             EMPLOYMENT AGREEMENT
                             --------------------

         THIS EMPLOYMENT AGREEMENT (the "Agreement"), made this 21st day of
June, 1995, is entered into by Physicians Quality Care, Inc., a Delaware
corporation with its principal place of business at 950 Winter Street, Suite
2410, Waltham, MA 02154 (the "Company"), and Jerilyn P. Asher, residing at 3
Craigie Circle, Cambridge, MA 02138 ("Asher").

         The Company recognizes that the future growth, profitability and
success of the business of the Company will be enhanced by the employment of
Asher. The Company desires therefore to secure the benefit of Asher's experience
and ability. In order to retain the services of Asher, the Company desires to
offer Asher a compensation package which recognizes the significance of her
individual contribution to the future growth, profitability and success of the
Company and allows her to share in the same while allowing her to draw a salary
commensurate with her knowledge and experience.

         NOW, THEREFORE, on the basis of the foregoing facts and in

period of thirty-six (36) months, expiring on June 21, 1998 unless otherwise
extended as hereinafter provided. The Term shall be automatically extended for
additional twelve-month periods on June 21, 1998 and on each June 21 thereafter,
unless the Company notifies Asher in writing that such extension shall not take
place, ninety (90) days prior to any such June 21 extension date; provided 
                                                                  --------
that, if a Change of Control of the Company (as defined in Section 15(b)) shall
- ----
have
<PAGE>
 
occurred during the original or extended Term of this Agreement, this Agreement
shall continue in effect for a period of not less than twenty-four (24) months
beyond the month in which such Change of Control occurred, as provided in
Section 15(a).

         3.  Position; Duties.
             -----------------

             (a)  The Company and Asher agree that, subject to the provisions of
this Agreement and subject to the direction of the Board of Directors of the

perform her duties and responsibilities without her prior written consent.

             (b)  Asher hereby accepts such employment and agrees to undertake
the duties and responsibilities inherent in such position and such other duties
and responsibilities as the Board shall from time to time reasonably assign to
her. Asher agrees to devote her entire business time, attention and energies to
the business and interests of the Company during the Term. Asher agrees to abide
by the written rules, regulations, instructions, personnel practices and
policies of the Company and any changes therein which may be adopted from time
to time by the Company.

         4.  Member of the Board. Throughout the Term, Asher shall be eligible 
             -------------------
to serve as a Director of the Company and a member of the Board. The Company
agrees that it shall nominate Asher for election as a Director of the Company at
all elections of the members of the Board during the Term unless Asher declines
to stand for election.

                                      -2-
<PAGE>
 
         5.  Compensation. As compensation for Asher's employment hereunder, the
             ------------
Company shall pay to Asher a base salary payable in equal semi-monthly
installments at the annual rate of $240,000 or such greater base salary as the
Board may from time to time approve, commencing on December 1, 1995.

         6.  Bonus. The Company intends to adopt a management incentive program
             -----
under which executives of the Company such as Asher would be entitled to receive
bonus payments of up to 100% of their base salary based upon (i) the achievement
of certain performance targets by the Company as set by the Board and (ii) the
achievement of certain individual performance targets agreed upon between the
Board and Asher (collectively, the "Officer Incentive Bonus"). Asher shall be
eligible to receive an Officer Incentive Bonus during each calendar year during
the Term, the amount of such Officer Incentive Bonus to be set and approved by
the Board. For the calendar year 1995, Asher shall be entitled to receive a pro

based upon her commencement of employment on June 21, 1995.

         7.  Benefits. Upon meeting all applicable eligibility requirements,
             --------

available to other members of senior management of the Company including,
without limitation, sick pay, participation in any medical, disability,
retirement and dental insurance plans that may be adopted by the Company and
participation in equity incentive plans, including stock option plans, of the
Company; provided that, in the event Asher fails to qualify for any medical or
         -------- ----
disability insurance plan that may be adopted by the Company, the Company shall
pay to Asher an amount which would enable her to purchase an insurance plan from
another carrier which provides substantially similar benefits to those provided
to other members of senior

                                      -3-
<PAGE>
 
management under the Company's plans; provided however, that such amount may be
                                      -------- -------  
capped by the Board in its discretion. Asher represents that on the date hereof,
she has no knowledge of any medical condition which might prevent her from
qualifying as a beneficiary under a standard medical or disability plan. During
the Term, Asher's benefits shall be maintained at least at the same level as are
presently in effect on the date hereof.

         8.  Vacation.  Asher shall be entitled to four (4) weeks of vacation 
             --------
time each year, to be pro-rated monthly for partial years, during the Term. If
Asher does not utilize all vacation in the year earned, the unused vacation time
in any year shall not carry over to the next year.

         9.  Expenses. The Company shall reimburse Asher for all reasonable
             --------

statements, vouchers and/or such other supporting information as the Company may
request, provided, however, that the amount available for such travel,
         --------  -------
entertainment and other expenses may be fixed in advance by the Board.

         10. Restricted Stock Award. Pursuant to the Company's 1995 Restricted
             ----------------------
Stock Plan (the "Restricted Stock Plan"), the Company shall issue to Asher
4,162,500 shares of Common Stock of the Company, $.01 par value per share (the
"Founder's Shares"), at a purchase price of $.01 per share, subject to vesting
and the Company's right to repurchase at $.01 per share, in the event that all
of Asher's Founder Shares do not vest and are forfeited in accordance with the
Restricted Stock Plan (which shall provide for, among other things, a vesting
schedule based on (i) performance targets for the Company as set by the Board,
(ii) performance targets for executive recipients as agreed to between the Chief
Executive Officer

                                      -4-

responsibilities; or an adverse and material alteration in her reporting
responsibilities, titles or offices, or any removal of her or failure to re-
elect her to any of such positions, except in connection with the termination of
her employment or retirement (which shall mean her voluntary termination of
employment after having attained age 70);

                                      -5-
<PAGE>
 
                  (iv)  any reduction in Asher's annual base salary or a
material reduction in fringe benefits as in effect on the date hereof or as the
same may be increased during the Term; and

                  (v)   any material breach by the Company of any material
provision of this Agreement which the Company fails to correct within thirty
(30) working days after receiving written notice thereof.

             (c)  In the event Asher is terminated by the Company without Cause
or Asher terminates her employment with Good Reason, the Company shall pay to
Asher an amount equal to two (2) times Asher's annual base salary (based on
Asher's base salary prevailing at the time of the termination).

             (d)  Payment pursuant to Section 11(c) shall be made in twenty-four
(24) equal monthly installments on the last day of each month after termination
of this Agreement pursuant to this Section 11.

             (e)  The parties hereto expressly acknowledge and agree that the
compensation and benefits payable to Asher upon a termination as specified in
this Section 11 will constitute full, reasonable and adequate compensation for
any such termination and that the payment of such compensation and benefits
shall fully satisfy and discharge any and all obligations of the Company to
Asher in connection with such termination.

         12. Termination By Asher Without Cause. Asher may terminate her
             ----------------------------------
employment hereunder without Cause and without Good Reason, provided that Asher
first gives to the Company a written notice of intent to terminate at least
ninety (90) days prior to the effective date of any such termination. All rights
of Asher under this Agreement shall terminate upon the effective date of the
termination of employment; provided, however, the Company shall pay to Asher any
                           --------- -------
base salary earned through the effective date of the termination and a

                                      -6-
<PAGE>
 
pro-rata share of the Officer Incentive Bonus earned during the calendar year in
which the termination of employment occurs.

         13. Termination of Asher For Cause
             ------------------------------

             (a)  Notwithstanding anything in this Agreement to the contrary,
the Company shall have the right to terminate Asher's employment hereunder for
Cause (as defined in Subsection (b) of this Section 13) by giving to Asher
written notice of such termination as of a date (not earlier than ten (10) days
after such notice) to be specified in such notice, and her employment hereunder
shall terminate on the date so specified, whereupon Asher shall be entitled to
receive her salary at the rate provided in Section 5 and any other compensation
or benefits provided in Sections 6, 7 and 8, only to the date on which
termination shall take effect.

             (b)  For purposes of this Section 13, "Cause" shall mean (i)
Asher's willful and continued failure materially to perform her duties with the
Company (other than any such failure resulting from her incapacity due to
physical or mental illness or any such actual or anticipated failure after the
issuance of a notice by Asher of termination for Good Reason), which is not
remedied within a reasonable period after a written demand for performance is
delivered to Asher which specifically identifies the manner in which it is
believed that Asher has not materially performed her duties; (ii) the willful
engagement by Asher in misconduct materially and demonstrably injurious to the
Company, or (iii) Asher's conviction of a felony or of a fraud or embezzlement
of the Company's property. For purposes of this Subsection (b), no act or
failure to act by Asher shall be considered "willful" unless done, or omitted to
be done, by Asher without good faith and without reasonable belief that Asher's
action or omission was in the best interest of the Company. For purposes of this
Agreement, Asher shall not be deemed to have been terminated for Cause unless
and until there shall

                                      -7-
<PAGE>
 
have been delivered to Asher a copy of a resolution, duly adopted by the
affirmative vote of not less than 66 2/3% of the entire membership of the Board
of the Company (excluding Asher) at a meeting called and held for this purpose
after reasonable written notice to Asher and an opportunity for her, together
with her counsel, to be heard by the Board, finding, in the good faith opinion
of the Board, misconduct of the type described in this Section 13(b), and
specifying the particulars thereof in detail.

         14. Termination In the Event of Disability or Death.
             ------------------------------------------------

             (a)  Disability. In the event that Asher shall fail, because of
                  ----------
illness or injury, to render the services contemplated by this Agreement for six
(6) consecutive calendar months or for shorter periods aggregating one hundred
eighty (180) or more business days in any twelve (12) month period, the Company
shall have the right to terminate Asher's employment hereunder by giving to
Asher written notice of termination. In the event Asher's employment is
terminated within the meaning of this Section 14(a), Asher shall receive her
salary at the rate provided in Section 5 and any other compensation and benefits
provided in Sections 6, 7 and 8, to the effective date of such termination. Such
termination pursuant to this Section 14(a) shall not affect any rights which
Asher may have at the time of termination pursuant to any insurance or other
death benefit, bonus, retirement, severance pay or stock award plans or
arrangements of the Company, or any equity incentive plan or any restricted
stock award or options thereunder, which rights shall continue to be governed by
the terms and provisions of any such plans and agreements.

             (b)  Death. During the Term of this Agreement, the Company shall 
                  -----
maintain a life insurance policy in the amount of $500,000, to be paid to
Asher's named beneficiaries in accordance with standard policy terms and
conditions. This Agreement in all other respects will terminate upon the death
of Asher except for the payment of Asher's base

                                      -8-
<PAGE>
 
salary at the rate provided in Section 5 and any other compensation and benefits
provided in Sections 6, 7 and 8 to the date of her death.

         15. Termination in the Event of a Change of Control.
             ------------------------------------------------

             (a)  In the event a Change in Control (as defined in Subsection (b)
below) shall occur during the Term and Asher's employment with the Company is
subsequently terminated or terminates for any reason within twenty-four (24)
months after such Change in Control other than by reason of (i) disability or
death, (ii) termination by the Company for Cause or (iii) termination by Asher
other than for Good Reason, Asher shall be entitled to receive the payments as
set forth in Subsections (c) and (d) of Section 11 (all to the same extent and
with the same effect as if such termination occurred by Asher for Good Reason)
and the vesting of the Founder's Shares and the exercisability of stock options
Asher then holds as set forth in Subsection (c) of this Section 15.

             (b)  A "Change in Control" shall occur or be deemed to occur if 
                     -----------------
any of the following events occur:

                  (i)   any individual, entity or group (within the meaning of
Section 13(d) (3) or 14(d) (2) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act")) (a "Person") is or becomes the "beneficial owner"
(as defined in Rule l3d-3 under the Exchange Act), directly or indirectly, of
securities of the Company representing 50% or more of the combined voting power
of the Company's then outstanding voting securities entitled to vote generally
in the election of directors (the "Outstanding Company Voting Securities");
provided, however, that for purposes of this subsection (i), the following
- --------  -------
acquisitions shall not constitute a Change of Control: (A) any acquisition
directly from the Company, (B) any acquisition by the Company, (C) any
acquisition by any employee benefit plan (or related trust) sponsored or
maintained by the Company or any corporation

                                      -9-
<PAGE>
 
controlled by the Company, or (D) any acquisition by any corporation pursuant to
a transaction which complies with clauses (A), (B) and (C) of paragraph (iii)
below;
                  (ii)  Individuals who, as of the Commencement Date, constitute
the Board (as of such date, the "Incumbent Board") cease for any reason to
constitute at least a majority of the Board; provided, however, that any
                                             --------  -------
individual becoming a director subsequent to the date hereof whose election, or
nomination for election by the Company's stockholders, was approved by a vote of
at least a majority of the directors then comprising the Incumbent Board shall
be, for purposes of this Agreement, considered as though such person were a
member of the Incumbent Board, excluding any individual whose initial assumption
of office occurs as a result of an actual or threatened election contest with
respect to the election or removal of directors or other actual or threatened
solicitation of proxies or consents by or on behalf of a Person other than the
Board; or

                  (iii) the stockholders of the Company approve a
reorganization, merger or consolidation of the Company with any other
corporation or the sale or other disposition of all or substantially all of the
assets of the Company (a "Business Combination"), in each case, unless,
following such Business Combination, (A) all or substantially all of the
individuals and entities who were the beneficial owners, respectively, of the
Outstanding Company Voting Securities immediately prior to such Business
Combination beneficially own, directly or indirectly, more than 50% of the
combined voting power of the then outstanding voting securities entitled to vote
generally in the election of directors of the corporation resulting from such
Business Combination (including, without limitation, a corporation which as a
result of such transaction owns the Company or all or substantially all of the
Company's assets either directly or through one or more subsidiaries) in
substantially the same proportions as their ownership of the Outstanding Company
Voting

                                     -10-
<PAGE>
 
Securities immediately prior to such Business Combination, (B) no Person
(excluding any corporation resulting from such Business Combination or any
employee benefit plan (or related trust) of the Company or such corporation
resulting from such Business Combination) beneficially owns, directly or
indirectly, 50% or more of the then outstanding shares of common stock of the
corporation resulting from such Business Combination or the combined voting
power of the then outstanding voting securities of such corporation except to
the extent that such ownership existed prior to the Business Combination and (C)
at least a majority of the members of the Board of Directors of the corporation
resulting from such Business Combination were members of the Incumbent Board at
the time of the execution of the initial agreement, or of the action of the
board, providing for such Business Combination; or

                  (iv)  Approval by the shareholders of the Company of a
complete liquidation or dissolution of the Company.

             (c)  The Asher Stock Restriction Agreement and all stock options
for the purchase of the Company's Common Stock granted to Asher by the Company
under any of the Company's stock option plans shall provide for acceleration of
the vesting of the Founder's Shares and the full and immediate exercisability of
each such option upon the occurrence of a Change of Control.

             (d)  Notwithstanding any other provisions of this Agreement, in the
event that any payment or benefit received or to be received by Asher in
connection with a Change of Control or the termination of Asher's employment
(all such payments and benefits, including those set forth in Subsections (c)
and (d) of Section 11 and Section 15(c) being hereafter called "Total
Payments"), would be subject (in whole or part), to the excise tax imposed under
Section 4999 of the Internal Revenue Code ("IRC") (the "Excise Tax"), then

                                     -11-
<PAGE>
 
the Total Payments may be reduced, in such order and manner as Asher may elect,
so that no portion of the Total Payments is subject to the Excise Tax if (i) the
net amount of such Total Payments, as so reduced (and after deduction of the net
amount of federal, state and local income tax on such reduced Total Payments) is
greater than (ii) the excess of (A) the net amount of such Total Payments,
without reduction (but after deduction of the net amount of federal, state and
local income tax on such Total Payments), over (B) the amount of Excise Tax to
which Asher would be subject in respect of such Total Payments. For purposes of
determining whether and the extent to which the Total Payments will be subject
to the Excise Tax, (i) no portion of the Total Payments the receipt or enjoyment
of which Asher shall have effectively waived in writing prior to the date of her
termination shall be taken into account, (ii) no portion of the Total Payments
shall be taken into account which in the opinion of tax counsel selected by the
Company does not constitute a "parachute payment" within the meaning of Section
280G(b)(2) of the IRC (including by reason of Section 280G(b) (4) (A) of the
IRC) and, in calculating the Excise Tax, no portion of such Total Payments shall
be taken into account which constitutes reasonable compensation for services
actually rendered, within the meaning of Section 280G(b) (4) (B) of the IRC, and
(iii) the value of any non-cash benefit or any deferred payment or benefit
included in the Total Payments shall be determined by the Company in accordance
with the principles of Sections 280G(d) (3) and (4) of the IRC. Prior to the
payment of any of the Total Payments, the Company shall provide Asher with its
calculation of the amounts referred to in this Section and such supporting
materials as are reasonably necessary for Asher to evaluate the Company's
calculations.

         16. Indemnification.  Asher shall be fully indemnified by the Company 
             ---------------
in her capacity as an officer and director of the Company to the extent
permitted by Delaware law.

                                     -12-
<PAGE>
 
         17. Non-Compete.
             -----------

             (a)  So long as Asher is employed by the Company and for a period
of two years after the termination or expiration of her employment, Asher will
not directly or indirectly:

                  (i)   as an individual proprietor, partner, stockholder,
officer, employee, director, joint venturer, investor, lender, or in any other
capacity whatsoever (other than as the holder of not more than one percent (1%)
of the total outstanding stock of a publicly held company), engage directly or
indirectly in any business or entity which (i) operates, develops or manages
physician practice management entities or (ii) develops, designs, produces,
markets or sells managed care products or services, of the kind or type
developed or which were being developed, produced, marketed or sold by the
Company while Asher was employed by the Company, to the extent such engagement
assists such business or entity in competing with the business conducted by the
Company in any city in which the Company conducts material operations; or

                  (ii)  recruit, solicit or induce, or attempt to induce, any
employee or employees of the Company to terminate their employment with, or
otherwise cease their relationship with, the Company; or

                  (iii) solicit, divert or take away, or attempt to divert or to
take away, the business or patronage of any of the clients, customers or
accounts, or prospective clients, customers or accounts, of the Company which
were contacted, solicited or served by Asher while employed by the Company.

             (b)  If any restriction set forth in this Section 17 is found by
any court of competent jurisdiction to be unenforceable because it extends for
too long a period of time or over too great a range of activities or in too
broad a geographic area, it shall be interpreted to

                                     -13-
<PAGE>
 
extend only over the maximum period of time, range of activities or geographic
area as to which it may be enforceable.

             (c)  The restrictions contained in this Section 17 are necessary
for the protection of the business and goodwill of the Company and are
considered by Asher to be reasonable for such purpose. Asher agrees that any
breach of this Section 17 will cause the Company substantial and irrevocable
damage and therefore, in the event of any such breach, in addition to such other
remedies which may be available, the Company shall have the right to seek
specific performance and injunctive relief.

         18. Proprietary Information and Developments.
             ----------------------------------------

             (a)  Proprietary Information.
                  -----------------------

                  (i)   Asher agrees that all information and know-how, whether
or not in writing, of a private, secret or confidential nature concerning the
Company's business, business relationships or financial affairs (collectively,
"Proprietary Information") is and shall be the exclusive property of the
Company. By way of illustration, but not limitation, Proprietary Information may
include inventions, products, processes, methods, techniques, formulas,
compositions, compounds, projects, developments, plans, research data, clinical

others outside the Company or use the same for any unauthorized purposes without
written approval by an officer of the Company, either during or after her
employment, unless and until such Proprietary Information has become public
knowledge without fault by Asher.

                  (ii)  Asher agrees that all files, letters, memoranda,
reports, records, data, sketches, drawings, laboratory notebooks, program
listings, or other written,

                                     -14-
<PAGE>
 
photographic, or other tangible material containing Proprietary Information,
whether created by Asher or others, which shall come into her custody or
possession, shall be and are the exclusive property of the Company to be used by
Asher only in the performance of her duties for the Company.

              (iii) Asher agrees that her obligation not to disclose or use
information, know-how and records of the types set forth in Subsection (a) of
this Section 18 also extends to such types of information, know-how, records and
tangible property of customers of the Company or suppliers to the Company or
other third parties who may have disclosed or entrusted the same to the Company
or to Asher in the course of the Company's business.

         (b)  Developments.
              ------------

              (i)   Asher will make full and prompt disclosure to the Company of
all inventions, improvements, discoveries, methods, developments, software, and
works of authorship, whether patentable or not, which are created, made,
conceived or reduced to practice by Asher or under her direction or jointly with
others during her employment by the Company, whether or not during normal
working hours or on the premises of the Company (all of which are collectively
referred to in this Agreement as "Developments").

              (ii)  Asher agrees to assign and does hereby assign to the Company
(or any person or entity designated by the Company) all her right, title and
interest in and to all Developments and all related patents, patent
applications, copyrights and copyright applications. However, Subsection (b) of
this Section 18 shall not apply to Developments which do not relate to the
present or planned business or research and development of the Company and which
are made and conceived by Asher not during normal working hours,

                                      -15-
<PAGE>
 
not on the Company's premises and not using the Company's tools, devices, 
equipment or Proprietary Information.

              (iii) Asher agrees to cooperate fully with the Company, both
during and after her employment with the Company, with respect to the
procurement, maintenance and enforcement of copyrights and patents (both in the
United States and foreign countries) relating to Developments. Asher shall sign
all papers, including, without limitation, copyright applications, patent
applications, declarations, oaths, formal assignments, assignment of priority
rights, and powers of attorney, which the Company may deem necessary or
desirable in order to protect its rights and interests in any Development.

         (c)  Other Agreements. Asher hereby represents that she is not
              ----------------
bound by the terms of any agreement with any previous employer or other party to
refrain from using or disclosing any trade secret or confidential or proprietary
information in the course of her employment with the Company or to refrain from
competing, directly or indirectly, with the business of such previous employer
or any other party. Asher further represents that her performance of all 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, knowledge or
data acquired by her in confidence or in trust prior to her employment with the
Company.

     19. Assignment. Neither this Agreement nor any rights or benefits
         ----------
hereunder shall be subject to execution, attachment or similar process nor may
this Agreement or any rights or benefits hereunder be assigned, delegated,
transferred, pledged or hypothecated, without the written consent of both
parties hereto, and any such assignment, delegation, transfer, pledge,
hypothecation, execution, attachment or similar process shall be null and void.

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

         (a)  The Company shall require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company to assume expressly
in writing and to agree to perform its obligations under this Agreement in the
same manner and to the same extent that the Company would be required to perform
it if no such succession had taken place. Failure of the Company to obtain an
assumption of this Agreement prior to the effectiveness of succession shall be a
breach of this Agreement. As used in this Agreement, "the Company" shall mean
the Company as defined above and any successor to its business or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

         (b)  This Agreement shall inure to the benefit of and be enforceable by
Asher's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. Any amounts payable by
the Company to Asher after the date of her death, unless otherwise provided
herein, shall be paid in accordance with the terms of this Agreement to her
devisee, legatee or other designee, or if there is no such designee, to her
estate.

     21. Severability. Whenever possible, each provision of this Agreement
         ------------
shall be interpreted in such manner as to be valid and effective under
applicable law, but if any provision of this Agreement is found to be prohibited
or invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity without invalidating the remainder of
such provision or the remaining provisions of this Agreement.

     22. Notices.  All notices, requests, demands and other communication 
         -------
hereunder shall be in writing and shall be deemed to have been duly given if 
personally delivered or if mailed by United States Postal Service certified or

                              EMPLOYMENT AGREEMENT

         WHEREAS, pursuant to an Employment Agreement dated as of June 21, 
1995 (the "Agreement"), Physicians Quality Care, Inc. (the "Company") and 
Jerilyn P. Asher ("Asher") entered into an employment relationship.

         WHEREAS, the Company and Asher wish to clarify the Agreement and to

         NOW THEREFORE, in consideration of these premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto, intending to be legally bound, agree as

         1. Section 5 of the Agreement is hereby amended to provide that Asher
shall be paid a base annual salary of $250,000 retroactively effective as of
June 21, 1995.

         2. Section 6 of the Agreement is hereby clarified to correct the
reference to a pro-rata portion of the annual Officer Incentive Bonus for 1995
from "five-twelfths" to "six- twelfths" (i.e., the six month period from July
21, 1995 through December 31, 1995, being the six full calendar months of 1995
Asher has worked for the Company).

         3. Section 8 of the Agreement is hereby amended to add a new clause at
the end thereof, as follows: "; provided, however, that upon receipt of approval
from the Company's Compensation Committee or, if there is no Compensation
Committee, the Company's Board of Directors, Asher may elect to receive
additional salary in lieu of any unused vacation time at a rate per week equal
to her annual base salary divided by fifty-two."

         4. Section 14(b) of the Agreement is hereby amended by inserting a new
sentence after the first sentence thereof, as follows: "Such life insurance
policy shall be a group term policy or such other form of insurance as may be
mutually satisfactory to the parties; provided, however, that such policy shall
contain a so-called conversion provision permitting Asher to continue coverage
at her own expense at the same benefit level after termination of the Agreement.

         IN WITNESS WHEREOF, authorized signatories of the parties have hereunto
set their hands as of this     day of January, 1996.

law and at equity, which Executive now has, ever had, or may hereafter have
against the respective Releasees arising contemporaneously with or prior to the
Initial Closing A (as defined in the Purchase Agreement) including, but not
limited to any rights to receive salary and bonus or reimbursement from the
Company prior to August 1, 1996.

     d. The Company and Executive hereby confirm that Executive's annual

3.   Options to Purchase.
     --------------------

     a.  Call Options. Upon any termination of the employment by the Company
         ------------
of Executive, the Company (or its designee) shall have the right to purchase
Shares held by the Executive or originally issued to Executive but held by one
or more Permitted Transferees of Executive (collectively, the "Call
Stockholder Group") on the following terms:

         i. Termination by Company for Cause. If such termination is
            --------------------------------
     the result of termination of Executive's employment by the Company for
     Cause, the Company (or its designee), upon written notice delivered within
     90 days of termination, (a) may purchase 50% of the Shares that are vested
     in accordance with Schedule A hereto ("Vested Shares") at a price equal to
     the Fair Market Value of such securities and (b) may purchase all Shares
     that are unvested in accordance with Schedule A hereto at Cost (without any
     rate of return). If such termination is a result of termination of
     Executive's employment by the Company without Cause, the Company shall have
     no right to purchase any of the Vested Shares.

         ii. Resignation of the Executive. If such termination is the
             ----------------------------
     result of Executive's resignation, the Company (or its designee), upon
     written notice delivered within 90 days of termination, (a) may purchase
     all or any portion of 35% of the Vested Shares at a price equal to the Fair
     Market Value of such securities and (b) may purchase all Shares that are
     unvested in accordance with Schedule A hereto at Cost (without any rate of
     return).

                                       -2-
<PAGE>
 
         iii. Voting Trust. Upon termination of Executive's employment
              ------------
     with the Company for any reason, Executive agrees to deposit all Shares not
     purchased by the Company (or its designee) pursuant to Section 3 hereof in
     a voting trust mutually agreeable to Executive, the Company and Bain
     containing the following terms and conditions (a) the voting trust shall
     terminate upon the earlier to occur of (i) five years from the date it was
     entered into and (ii) the date of a Qualified Public Offering, (b) the
     trustee shall exercise all voting and other rights with respect to the
     Shares subject to the voting trust as directed by Bain, and (c) Executive
     shall have the right to transfer all or any portion of her beneficial
     interest in the voting trust subject to restrictions analogous to the
     restrictions on transfers of Shares contained in the Stockholders
     Agreement.

         iv. Sale or IPO. In the event the Company consummates the
             -----------
     initial Public Offering of its Shares or sells the Company or substantially
     all of its assets within twelve months of termination of Executive's
     employment, the Company shall promptly pay Executive with respect to each
     Share purchased at Fair Market Value pursuant to Section 3.1.2 hereof the
     positive difference, if any, between (a) the price that would have been
     paid for such Share if the Fair Market Value of a Share were equal to the
     net proceeds received by the Company with respect to each Share sold in the
     Public Offering or in the case of a sale of the Company, the amount per
     share paid to the shareholders of the Company (appropriately adjusted for
     stock splits, reverse stock splits, stock dividends and the like), and (b)
     the amount previously paid to Executive with respect to such Share pursuant
     to Section 3 hereof.

     b. Determination of Fair Market Value. (a) For purposes of this Section
        ----------------------------------
3, the term "Fair Market Value" shall mean, as of any date, the fair value of
any Share as of the applicable date on the basis of a sale of such Share in an
arms length private sale between a willing buyer and a willing seller, neither
acting under compulsion, as determined by the Board; (b) at any time when more
than 15% of the Shares then outstanding has been offered and sold pursuant to
one or more Public Offerings, the Fair Market Value of any Share shall be equal
to the average of the sum of the closing prices of the Shares for the 30 trading
days immediately prior to the date on which Share becomes subject to repurchase
under this Section 3. In determining Fair Market Value, the Board shall (a)
consider, in addition to other factors that it determines in good faith to be
relevant, the purchase price of the Shares in recent (i) arms-length sales of
Shares by the Company, (ii) transfers of Shares by a Stockholder in an
arms-length transaction and (b) not give effect to any discount which may
otherwise be attributable to the fact that such Shares which are the subject of
such valuation (i) constitute less than a majority of the Shares outstanding
and/or (ii) are restricted as to transfer as provided herein.

     c. "Cause" shall mean for purposes of Section 3 of this Agreement, in
         -----
the context of termination of the employment of the Executive, any of the
following events or conditions: (i) Executive's gross negligence or willful
misconduct which causes material injury to the Company or any of its Affiliates
and is not cured within twenty-one (21) days after written notice by the Company
to Executive, (ii) any act of fraud, embezzlement or other material dishonesty,
(iii) conviction of, or plea of nolo contendere to, any felony or any other
crime involving fraud, dishonesty or moral turpitude, or (iv) willful conduct
which causes criminal

                                       -3-
<PAGE>
 
or material civil liabilities to the Company or its Affiliates thereof. For
purposes of (iv) above, no act or failure to act on the part of the Executive
shall be considered "willful" unless it is done or omitted to be
done by the Executive in bad faith or without reasonable belief that the
Executive's action or omission was in the best interests of the Company and its
Subsidiaries. The cessation of employment of the Executive shall not be deemed
to be for Cause unless and until (i) a written notice has been delivered to the
Executive by the Board which specifically identifies the Cause which is the
Board's basis for termination and (ii) the Board has delivered to the Executive
a copy of a resolution duly adopted by the affirmative vote of not less than a
majority of the entire membership of the Board (excluding the Executive) at a
meeting of the Board called and held for such purpose (after reasonable notice
is provided to the Executive and the Executive is given an opportunity, together
with counsel, to be heard before the Board), finding that, in the good faith
opinion of the Board, the Executive has engaged in the conduct described in the
Board's notice and specifying the particulars thereof in detail.

     d. Period. The foregoing provisions of this Section 3 shall 
        ------
expire on the date of a Qualified Public Offering.

     e. Construction. The foregoing provisions of this Section 3 are not
        ------------
intended, and shall not be construed, to eliminate, waive or otherwise affect
(a) the restrictions on transfer, vesting requirements or termination provisions
which may apply to any Share or Option by its terms or under provisions of the
Company's 1995 Restricted Stock Plan, Equity Incentive Plan or other equity or
option plan pursuant to which such Share or Option was granted or other
governing documentation, or (b) any provisions of the Stockholders Agreement
except Section 5.1 thereof. Without limiting the foregoing, Sections 5.4 and 10
of the Stockholders Agreement shall be applicable to all matters contemplated by
Section 3 hereof.

4.   Assignment, etc.  None of the parties shall have the right to assign 
     ---------------
     this Agreement.

5.   Amendments and Waivers. No amendment or waiver of any term, provision
     ----------------------
     or condition of this Agreement shall be effective, unless in writing
     and executed by each of the Company, the Executive and Bain (which is
     an intended third party beneficiary hereof). No waiver on any one
     occasion shall extend to or effect or be construed as a waiver of any
     right or remedy on any future occasion. No course of dealing of any
     person nor any delay or omission in exercising any right or remedy
     shall constitute an amendment of this Agreement or a waiver of any
     right or remedy of any party hereto.

6.   Miscellaneous.

     a.  Choice of Law. This Agreement shall be governed by and construed in
         -------------

applicable thereto prior to such Transfer and that such Permitted Transferee is

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

<PAGE>
 
Company shall each select a physician and these two together shall select a
third physician, whose determination as to disability shall be binding on all
parties;

          (d) At the election of either party, upon not less than sixty (60)

Company shall pay to the estate of Fuller or to Fuller, as the case may be, the
compensation which would otherwise be payable to Fuller up to the end of the
month in which the termination of his employment because of death or disability
occurs.
          (c) Survival.  The provisions of Sections 13 and 14 shall survive the
termination of this Agreement.

     11.  Termination in the Event of a Change of Control.

          (a) In the event a Change in Control (as defined in Subsection (b)

subsequently terminated or terminates for any reason within twenty-four (24)
months after such Change in Control other than by reason of (i) disability or
death, or (ii) termination by the Company for 

                                       5
<PAGE>
 
Cause, Fuller shall be entitled to receive the vesting of the Founder's Shares
and the exercisability of stock options Fuller then holds as set forth in
Subsection (c) of this Section 11. 


          (b) A "Change in Control" shall occur or be deemed to occur if any of
the following events occur:

              (i)  any individual, entity or group (within the meaning of
Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act")) (a "Person") is or becomes the "beneficial owner" (as
defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of
securities of the Company representing 50% or more of the combined voting power
of the Company's then outstanding voting securities entitled to vote generally
in the election of directors (the "Outstanding Company Voting Securities");
provided however, that for purposes of this subsection (i), the following
acquisitions shall not constitute a Change of Control: (A) any acquisition
directly from the Company, (B) any acquisition by the Company, (C) any
acquisition by any employee benefit plan (or related trust) sponsored or
maintained by the Company or any corporation controlled by the Company, or (D)
any acquisition by any corporation pursuant to a transaction which complies with
clauses (A), (B) and (C) of paragraph (iii) below;

              (ii) Individuals who, as of the Commencement Date, constitute the
Board (as of such date, the "Incumbent Board") cease for any reason to
constitute at least a majority of the Board; provided however, that any
individual becoming a director subsequent to the date hereof whose election, or
nomination for election by the Company's stockholders, was approved by a vote of
at least a majority of the directors then comprising the Incumbent Board shall
be, for purposes of this Agreement, considered as though such person were a
member of the Incumbent Board, excluding any individual whose initial assumption
of office 

                                       6
<PAGE>
 
occurs as a result of an actual or threatened election contest with respect to
the election or removal of directors or other actual or threatened solicitation
of proxies or consents by or on behalf of a Person other than the Board; or

              (iii) the stockholders of the Company approve a reorganization,
merger or consolidation of the Company with any other corporation or the sale or
other disposition of all or substantially all of the assets of the Company (a
"Business Combination"), in each case, unless, following such Business
Combination, (A) all or substantially all of the individuals and entities who
were the beneficial owners, respectively, of the Outstanding Company Voting
Securities immediately prior to such Business Combination beneficially own,
directly or indirectly, more than 50% of the combined voting power of the then
outstanding voting securities entitled to vote generally in the election of
directors of the corporation resulting from such Business Combination
(including, without limitation, a corporation which as a result of such
transaction owns the Company or all or substantially all of the Company's assets
either directly or through one or more subsidiaries) in substantially the same
proportions as their ownership of the Outstanding Company Voting Securities
immediately prior to such Business Combination, (B) no Person (excluding any
corporation resulting from such Business Combination or any employee benefit
plan (or related trust) of the Company or such corporation resulting from such
Business Combination) beneficially owns, directly or indirectly, 50% or more of,
the then outstanding shares of common stock of the corporation resulting from
such Business Combination or the combined voting power of the then outstanding
voting securities of such corporation except to the extent that such ownership
existed prior to the Business Combination and (C) at least a majority of the
members of the Board of Directors of the corporation resulting from such
Business Combination were members of the Incumbent Board at the time of the
execution of 

                                       7
<PAGE>
 
the initial agreement, or of the action of the board, providing for such
Business Combination; or

               (iv) Approval by the shareholders of the Company of a complete
liquidation or dissolution of the Company.

          (c) The Fuller Stock Restriction Agreement and all stock options for
the purchase of the Company's Common Stock granted to Fuller by the Company
under any of the Company's stock option plans shall provide for acceleration of
the vesting of the Founder's Shares and the full and immediate exercisability of
each such option upon the occurrence of a Change of Control.

          (d) Notwithstanding any other provisions of this Agreement, in the
event that any payment or benefit received or to be received by Fuller in
connection with a Change of Control or the termination of Fuller's employment
(all such payments and benefits, including those set forth in Section 11(c)
being hereafter called "Total Payments"), would be subject (in whole or part),
to the excise tax imposed under Section 4999 of the Internal Revenue Code
("IRC") (the "Excise Tax"), then the Total Payments may be reduced, in such
order and manner as Fuller may elect, so that no portion of the Total Payments
is subject to the Excise Tax if (i) the net amount of such Total Payments, as so
reduced (and after deduction of the net amount of federal, state and local
income tax on such reduced Total Payments) is greater than (ii) the excess of
(A) the net amount of such Total Payments, without reduction (but after
deduction of the net amount of federal, state and local income tax on such Total
Payments), over (B) the amount of Excise Tax to which Fuller would be subject in
respect of such Total Payments.  For purposes of determining whether and the
extent to which the Total Payments will be subject to the Excise Tax, (i) no
portion of the Total Payments the receipt or enjoyment of which Fuller shall
have effectively waived in 

                                       8
<PAGE>
 
writing prior to the date of his termination shall be taken into account, (ii)
no portion of the Total Payments shall be taken into account which in the
opinion of tax counsel selected by the Company does not constitute a "parachute
payment" within the meaning of Section 280G(b)(2) of the IRC (including by
reason of Section 280G(b)(4)(A) of the IRC) and, in calculating the Excise Tax,
no portion of such Total Payments shall be taken into account which constitutes
reasonable compensation for services actually rendered, within the meaning of
Section 280G(b)(4)(B) of the IRC, and (iii) the value of any non-cash benefit or
any deferred payment or benefit included in the Total Payments shall be
determined by the Company in accordance with the principles of Sections
280G(d)(3) and (4) of the IRC. Prior to the payment of any of the Total
Payments, the Company shall provide Fuller with its calculation of the amounts
referred to in this Section and such supporting materials as are reasonably
necessary for Fuller to evaluate the Company's calculations.

     12.  Indemnification.  Fuller shall be fully indemnified by the Company in
his capacity as an officer and director of the Company to the extent permitted
by Delaware law.

     13.  Non-Compete.

          (a) So long as Fuller is employed by the Company and for a period of
one year after the termination or expiration of his employment, Fuller will not
directly or indirectly:

              (i)   as an individual proprietor, partner, stockholder, officer,
employee, director, joint venturer, investor, lender, or in any other capacity
whatsoever (other than as the holder of not more than one percent (1%) of the
total outstanding stock of a publicly held company), engage directly or
indirectly in any business or entity which (i) operates, develops or manages
physician practice management entities or (ii) develops, designs, produces,
markets or sells managed care products, of the kind or type developed or 

                                       9
<PAGE>
 
which were being developed, produced, marketed or sold by the Company while
Fuller was employed by the Company, to the extent such engagement assists such
business or entity in competing with the business conducted by the Company in
any city in which the Company conducts material operations; or

              (ii)  recruit, solicit or induce, or attempt to induce, any
employee or employees of the Company to terminate their employment with, or
otherwise cease their relationship with, the Company; or

              (iii) solicit, divert or take away, or attempt to divert or
to take away, the business or patronage of any of the clients, customers or
accounts, or prospective clients, customers or accounts, of the Company which
were contacted, solicited or served by Fuller while employed by the Company.

          (b) The Company acknowledges and agrees that, notwithstanding anything
else to the contrary contained herein, none of Fuller's activities undertaken in
connection with his employment by the Massachusetts General Hospital and the
Harvard Medical School, including but not limited to his activities as a
director or manager of any physician's network or physician's organization or of
any integrated healthcare delivery system developed by Massachusetts General
Hospital and Harvard Medical School, shall be deemed a violation of this Section
13.  If any restriction set forth in this Section 13 is found by any court of
competent jurisdiction to be unenforceable because it extends for too long a
period of time or over too great a range of activities or in too broad a
geographic area, it shall be interpreted to extend only over the maximum period
of time, range of activities or geographic area as to which it may be
enforceable.

          (c) The restrictions contained in this Section 13 are necessary for
the protection of the business and goodwill of the Company and are considered by
Fuller to be 

                                       10
<PAGE>
 
reasonable for such purpose. Fuller agrees that any breach of this Section 13
will cause the Company substantial and irrevocable damage and therefore, in the
event of any such breach, in addition to such other remedies which may be
available, the Company shall have the right to seek specific performance and
injunctive relief.

     14.  Proprietary Information and Developments.

          (a) Proprietary Information.

              (i)   Fuller agrees that all information and know-how, whether or
not in writing, of a private, secret or confidential nature concerning the
Company's business, business relationships or financial affairs (collectively,
"Proprietary Information") is and shall be the exclusive property of the
Company. By way of illustration, but not limitation, Proprietary Information may

compositions, compounds, projects, developments, plans, research data, clinical
data, financial data, personnel data, computer programs, and customer and
supplier lists and contracts at or knowledge of customers or prospective
customers of the Company. Fuller will not disclose any Proprietary Information
to others outside the Company or use the same for any unauthorized purposes
without written approval by an officer of the Company, either during or after
his employment, unless and until such Proprietary Information has become public
knowledge without fault by Fuller.

              (ii)  Fuller agrees that all files, letters, memoranda, reports,
records, data, sketches, drawings, laboratory notebooks, program listings, or
other written, photographic, or other tangible material containing Proprietary
Information, whether created by Fuller or others, which shall come into his
custody or possession, shall be and are the exclusive property of the Company to
be used by Fuller only in the performance of his duties for the Company.

                                       11
<PAGE>
 
              (iii) Fuller agrees that his obligation not to disclose or
use information, know-how and records of the types set forth in Subsection (a)
of this Section 14, also extends to such types of information, know-how, records
and tangible property of customers of the Company or suppliers to the Company or
other third parties who may have disclosed or entrusted the same to the Company
or to Fuller in the course of the Company's business.

          (b) Developments.

              (i)   Fuller will make full and prompt disclosure to the Company
of all inventions, improvements, discoveries, methods, developments, software,
and works of authorship, whether patentable or not, which are created, made,
conceived or reduced to practice by Fuller or under his direction or jointly
with others during his employment by the Company, whether or not during normal
working hours or on the premises of the Company (all of which are collectively
referred to in this Agreement as "Developments").

              (ii)  Fuller agrees to assign and does hereby assign to the
Company (or any person or entity designated by the Company) all his right, title
and interest in and to all Developments and all related patents, patent
applications, copyrights and copyright applications. However, Subsection (b) of
this Section 14 shall not apply to Developments which do not relate to the
present or planned business or research and development of the Company and which
are made and conceived by Fuller not during his working hours for the Company,
not on the Company's premises and not using the Company's tools, devices,
equipment or Proprietary Information.

              (iii) Fuller agrees to cooperate fully with the Company, both
during and after his employment with the Company, with respect to the
procurement, maintenance and enforcement of copyrights and patents (both in the
United States and foreign countries) 

                                       12
<PAGE>
 
relating to Developments. Fuller shall sign all papers, including, without
limitation, copyright applications, patent applications, declarations, oaths,
formal assignments, assignment of priority rights, and powers of attorney, which
the Company may deem necessary or desirable in order to protect its rights and
interests in any Development.

          (c) Other Agreements.  Fuller hereby represents that he is not bound
by the terms of any agreement with any previous employer or other party to
refrain from using or disclosing any trade secret or confidential or proprietary
information in the course of his employment with the Company or to refrain from
competing, directly or indirectly, with the business of such previous employer
or any other party.  Fuller further represents that his performance of all 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, knowledge or
data acquired by him in confidence or in trust prior to his employment with the
Company.

     15.  Assignment.  Neither this Agreement nor any rights or benefits
hereunder shall be subject to execution, attachment or similar process nor may
this Agreement or any rights or benefits hereunder be assigned, delegated,
transferred, pledged or hypothecated, without the written consent of both
parties hereto, and any such assignment, delegation, transfer, pledge,
hypothecation, execution, attachment or similar process shall be null and void.

     16.  Successors; Binding Agreement.

          (a) The Company shall require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company to assume expressly
in writing and to agree to perform its obligations under this Agreement in the
same manner and to the same extent that the Company would 

                                       13
<PAGE>
 
be required to perform it if no such succession had taken place. Failure of the
Company to obtain an assumption of this Agreement prior to the effectiveness of
succession shall be a breach of this Agreement. As used in this Agreement, "the
Company" shall mean the Company as defined above and any successor to its
business or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law, or otherwise.

          (b) This Agreement shall inure to the benefit of and be enforceable by

devisee, legatee or other designee, or if there is no such designee, to his
estate.

     l7.  Severability.  Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be valid and effective under
applicable law, but if any provision of this Agreement is found to be prohibited
or invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity without invalidating the remainder of
such provision or the remaining provisions of this Agreement.

     18.  Notices.  All notices, requests, demands and other communication
hereunder shall be in writing and shall be deemed to have been duly given if
personally delivered or if mailed by United States Postal Service certified or

     3.  TERM AND POSSESSION.

              ----

Termination Date as set forth in Section 1.10, unless sooner terminated as
provided in this Lease.

         3.2  Possession.   Tenant agrees that if Landlord is unable to deliver
              ----------                                                       
possession of the Premises to Tenant on the Estimated Commencement Date,
Landlord shall not be liable for any damage caused thereby, nor shall this Lease
be void or voidable. Under such circumstances, the term of this Lease shall not
commence and the rent and payments for expenses which Tenant is obligated to pay
shall not commence until the Premises are ready for occupancy by Tenant and the
Termination Date of this Lease shall be based on the Lease Term as stated in
Section 1.8 of this Lease, unless such delay is the fault or responsibility of
Tenant.  If Landlord tenders possession of the Premises to Tenant prior to the
Estimated Commencement Date, and if Tenant elects to accept such prior tender,
the term of this Lease shall commence on  the date Tenant takes possession of
the Premises and all of the terms, covenants, and conditions of this Lease,
including the payment of rent and other expenses, shall be effective as of such
date.  Notwithstanding the fact that the term of this Lease may commence earlier

              ---------------                                                   
provided in this Lease and observing and performing all of the terms, covenants,
and conditions to be observed and performed by Tenant hereunder, Tenant shall
peaceably

                                       3
<PAGE>
 
and quietly hold, occupy, enjoy, manage, and operate the Premises without
hindrance or molestation by Landlord during the term of this Lease or by any
person or persons claiming under Landlord, subject to all of the provisions of
this Lease.

         3.5  Security Deposit. On delivery to Landlord of a copy of this Lease
              ----------------                                                 
executed by Tenant, Tenant shall deposit with Landlord the amount set forth in
Section 1.13 as security for the performance by Tenant of its obligations under
this Lease. Landlord may apply all or any portion of such security deposit in
payment of any obligation of Tenant under this Lease in default.  If Landlord so
applies any portion of such security deposit, Tenant shall within ten (10) days
after written demand from Landlord, restore such deposit to the full amount
provided in this Lease.  Landlord shall not be required to pay interest to
Tenant on such security deposit or to keep such security deposit separate from
its general accounts.  Such deposit shall be returned to Tenant at the
termination of the Lease if Tenant has discharged its obligations under this
Lease in full.

     4.  RENT.
         ---- 

         4.1  Payment of Rent. Tenant shall pay the monthly Rental, without any
              ---------------
prior demand therefor and without any deduction or offset whatsoever, in lawful
money of the United States of America, to Landlord on the first day of each
calendar month during the term of this Lease as rent for the Premises for such
month. Tenant shall make payments of rent and other expenses to Landlord at the
Building Manager's office at the Building or at other such address as Landlord
may from time to time request in writing. If the term of this Lease commences
other than on the first day of a month or ends other than on the last day of a
month, the rent for a partial month shall be prorated on a thirty (30) day
month, based on the number of days in such month that this Lease is in effect.

         4.2  Monthly Rental.    The Monthly Rental from the commencement of the
              --------------                                                    
term of this Lease through December 31, 1997, shall be the Initial Monthly
Rental as provided in Section 1.11 hereof.  The Monthly Rental for any
succeeding calendar year shall be determined by (i) multiplying the difference
between the Monthly Rental for the immediately preceding calendar year and
$1,476.67 by the CPI Adjustment for such year and (ii) adding to such amount
$1,476.67;  however, in no event shall the Monthly Rental be less than the
Initial Monthly Rental.  The CPI Adjustment for a calendar year shall be a
fraction, the numerator of which shall be the average CPI for the twelve months
ending with the September immediately preceding such calendar year and the
denominator of which shall be the average CPI for the twelve months ending with
the September before the September immediately preceding such calendar year.
The term "CPI" as used in this Lease shall mean the Consumer Price Index for All
Urban Customers - All Items - U.S. City Average (1967=100 or the then current
basis, if changed by the United States Department of Labor) published by the
United States Department of Labor, Bureau of Statistics.  If the issuance of the
CPI by the federal government is

                                       4
<PAGE>
 
discontinued, the Landlord shall use for the CPI the official index published by
a  federal governmental agency which is most nearly equivalent to the CPI.  If
no such index is available, then Landlord shall use such index or procedure
which reasonably reflects increases or decreases in consumer prices in the
United States.  If the rental payments determined pursuant to this Section 4.2
exceed that allowed by the terms of any valid governmental restriction which
limits the amount of rent or if the rental payments described pursuant to this
Section 4.2 exceed any limitation otherwise imposed by this Lease, the amount of
rent or other payments shall be the maximum permitted by such governmental
restriction and by such limitation; however, all increases or decreases in rent
or other payments provided in this Lease shall be calculated thereafter based
upon the amount of the rent which would have been payable under the Lease as if
such government restriction or other limitation had not limited the rent payable
under the terms of this Lease.  As used herein "calendar year" means a period
ending December 31.

     5.  ADDITIONAL EXPENSES.
         ------------------- 

         5.1  Additional Expenses Payable By Tenant. Tenant shall pay a
              -------------------------------------

to be provided by Landlord by reason of any use by Tenant of any utilities or
services in excess of utilities or services customarily provided for general

any time other than the normal business hours of generally recognized business
days and shall also pay any costs reasonably incurred by Landlord to meter or
otherwise measure the amount of such utilities or services used by Tenant.
Tenant shall pay for any additional or unusual janitorial services required by
reason of Tenant's use of the Premises or by reason of improvements in the
Premises other than Landlord's "Building Standard" improvements. If the

cost if only Landlord's "Building Standard" improvements were installed in the
Premises or Tenant's use or the conduct of business on the Premises or in the
Building, whether or not with Landlord's consent and whether or not otherwise
permitted by this Lease, results in any increase in premiums for the insurance
carried by Landlord with respect to the Building, Tenant shall pay any such
increase in premiums within ten (10) days after being billed by Landlord.

to the telephone, plumbing, heating, ventilation, air conditioning, elevator,
electrical, or other mechanical systems or cleaning services, by reason of
accident, emergency, repairs, alterations, improvements, or shortages or lack of

Lease, any utilities or services may be conserved by Landlord without abatement

              -------------------------------                                
Landlord shall obtain and keep in full force and effect fire and extended
coverage insurance with a vandalism and malicious mischief endorsement for the
Building  and public liability insurance in such reasonable amounts with such
reasonable deductions as would be carried by a prudent owner of a similar
building in the area, or which the first mortgagee of the Building reasonably
deems necessary in connection with the operation of the Building.  Landlord may
obtain insurance for the Building and the rents from the Building against such
other perils as Landlord reasonably considers appropriate.  Tenant acknowledges
that it will not be a named insured in such policy and that it has no right to
receive any proceeds from any such insurance policies carried by Landlord.

         9.2 Tenant's Insurance. During the entire term of the Lease, Tenant
             ------------------
shall obtain and keep in full force and effect, at its sole cost and expense,
the following insurance: (i) fire and extended coverage insurance with a water
damage and sprinkler damage endorsement and with a vandalism and malicious
mischief endorsement for property of Tenant located in the Building in an amount
not less than ninety percent (90%) of its cash value for any property such as
standard office furniture, furnishings, equipment, files, and supplies and in an
amount of one hundred percent (100%) of its cash value for any properties such
as cash, antiques, art objects, and jewelry, (ii) comprehensive general
liability insurance, including personal injury and property damage insuring
against all claims and liability arising out of the use or occupancy of the
Premises with limits as appropriate to Tenant's use of the Premises but not less
than $2,000,000, and (iii) insurance against interruption of Tenant's business
and loss of Tenant's business records in such amount as appropriate to Tenant's
business, unless Tenant shall provide, in writing, evidence of self insurance
pertaining to interruption of Tenant's business and loss of Tenant's business
records. All insurance policies shall provide that they cannot be canceled
without twenty (20) days prior written notice to Landlord and any other person
holding an interest in the Building designated by Landlord. Tenant shall deliver
copies of such policies to Landlord on request. Tenant may, by written notice of
such election to Landlord, elect to be a self-insurer of its property such as
office furniture, furnishings, equipment, files and supplies, cash, securities,
antiques, art objects, and jewelry and against interruption of Tenant's business
and loss of Tenant's business records. As an alternate to copies of Tenant's
insurance policies, Landlord agrees to accept certificates of such insurance
which are in a form satisfactory to Landlord.

         9.3 Indemnification. Tenant hereby waives all claims against Landlord,
             ---------------
its agents and employees for loss, theft, or damage to equipment, furniture,
records, and other property on or about the Premises, for loss or damage to
Tenant's business or death or injury to persons on or about the Premises or the
Building, except to the extent

                                       8
<PAGE>
 
caused by the active negligence or willful misconduct of Landlord, its agents or
employees.  Tenant shall indemnify and hold harmless  Landlord, its agents and
employees from and against any and all claims and liability for the loss, theft,
or damage to property on or about the Premises except Tenant's indemnification
shall not include an indemnification for liability for the active negligence or
willful misconduct of Landlord, its agents or employees.  Tenant shall indemnify
and hold Landlord, its agents and employees harmless from and against any and
all claims and liability arising from any breach or default by Tenant in the
performance of any obligation of Tenant under this Lease or arising from the
negligence or willful misconduct of Tenant, its agents, employees, or visitors.
Landlord shall not be liable to Tenant for any negligence or act of any occupant
or invitee of any owner or occupant or invitee of any owner or occupant of any
property adjoining the Building other than Landlord, its agents and employees.

         9.4 Waiver of Subrogation. Without limiting the obligation of Tenant to
             ---------------------
maintain insurance which permits waiver of subrogation (unless otherwise
approved in writing by Landlord), Landlord and Tenant hereby waive all causes of
action and rights of recovery against each other, against all subtenants or
assignees of Tenant, against all other tenants of the Building and their
assignees and sublessees and against any other person or entity holding an
interest in the Building (together, the "Affected Parties"), and against the
agents, officers, and employees of the Affected Parties, for any loss occurring
to the property of the Affected Parties resulting from any of the perils insured
against under any and all casualty insurance policies in effect at the time of
any such loss regardless of cause of origin of such loss, including the
negligence of the Affected Parties or the agents, officers, or employees of the
Affected Parties, to the extent of any recovery on such policies of insurance,
except to the extent that any of such policies of insurance are invalidated, in
whole or part, by said waiver, and so long as such policies of insurance shall
contain (and Landlord and Tenant hereby agree to use their best efforts to cause
such policies to contain), by endorsement or otherwise, a clause in such form or
having substantially the same effect as the following: "It is hereby stipulated
that this insurance shall not be invalidated in whole or in part should the
insured or any of them waive in writing prior to a loss any or all rights of
recovery against any person or entity for loss occurring to the property
described herein." Any self-insurance by Tenant shall be deemed to include such
waiver of subrogation against the Affected Parties. The obligation of Landlord
to use its best efforts to cause such policies to contain the above-described
clause shall not obligate Landlord to obtain such insurance from insurance
companies unacceptable to Landlord nor to incur premium charges therefor which
exceed one hundred ten percent (110%) of the premium charges for such insurance
which does not include such a clause. The obligation of Tenant to use its best
efforts to cause such policies to contain the above-described clause shall not
obligate Tenant to obtain such insurance for the benefit of the Affected Parties
other than Landlord from insurance companies unacceptable to Tenant nor to incur
premium charges therefor which exceed one hundred ten percent (110%) of the
premium charges for such insurance which does not include such a clause
benefitting the Affected Parties other than Landlord. Landlord shall promptly
notify Tenant in writing if such policies

                                       9
<PAGE>
 
of Landlord do not contain the above-described clause.  Tenant shall promptly
notify Landlord in writing if such policies of Tenant do not contain the above-
described clause, and in such event, Landlord shall promptly endeavor to notify
the other Affected Parties of such event.

     10.  DAMAGE OR DESTRUCTION
          ---------------------

          10.1 Repair of Damage. If the Premises or the Building are damaged or
               ---------------- 
destroyed by fire or other casualty covered by the usual form of fire and
extended coverage, Landlord shall commence repair or restoration within sixty
(60) days of such damage or destruction and shall diligently pursue such repair
and restoration to completion unless this Lease is terminated as provided
herein. Landlord shall pay the cost of repair to any damage or destruction of
the Building or the Premises caused by the negligence or willful misconduct of
Landlord, its agents or employees. Tenant shall pay the reasonable cost of
repair of any damage or destruction of the Premises except to the extent caused
by defects in construction of the Building or the negligence or willful
misconduct of Landlord, its agents or employees. Tenant shall pay the reasonable
cost of repair of any damage or destruction of the Building caused by the
negligence or willful misconduct of Tenant, its employees, agents, or visitors.
The costs of repair of the Building or Premises shall include a reasonable
overhead and profit charge by Landlord. Tenant's obligation to pay the cost of
repairs for damage or destruction to the Premises or the Building shall be
reduced by any insurance proceeds payable to Landlord for such damage or
destruction, but only to the extent such insurance provides for a waiver of
subrogation which permits such reduction of Tenant's obligations. Tenant shall
vacate such portion of the Premises as Landlord reasonably requires to enable
Landlord to repair the Premises or Building.

         10.2 Abatement. If the Premises are damaged or destroyed by fire or
              ---------
other casualty not caused by the negligence or willful misconduct of Tenant, its
agents, employees, or visitors, the Monthly Rental shall abate until such damage
or destruction is repaired in proportion to the reduction of the area of the
Premises usable by Tenant. Except as specifically provided in this Lease, this
Lease shall not terminate, Tenant shall not be released from any of its
obligations under this Lease, the rent and other expenses payable by Tenant
under this Lease shall not abate and Landlord shall have no liability to Tenant
for any damage or destruction to the Premises or the Building of any
inconvenience or injury to Tenant by reason of any maintenance, repairs,
alterations, decoration, additions, or improvements to the Premises or the
Building.

         10.3 Termination by Landlord. If the Building is damaged or destroyed,
              -----------------------
Landlord shall have the option to terminate this Lease within sixty (60) days of
such damage, if Landlord reasonably determines that the cost of repair to the
Building exceeds thirty percent (30%) of the value of the Building exclusive of
the land prior to such damage. If the Premises are damaged or destroyed,
Landlord shall have the option to terminate the term of this Lease within sixty
(60) days of the date of such damage or

                                       10
<PAGE>
 
destruction if the cost of repair of the Premises, as reasonably determined by
Landlord, exceeds the insurance proceeds estimated by Landlord to be payable to
Landlord for such damage or destruction, unless the Tenant agrees in writing to
pay any cost of repairs of the Premises in excess of such insurance proceeds
within fifteen (15) days of receipt by Tenant of written notice from Landlord of
its intention to terminate this Lease pursuant to this sentence.

         10.4  End of Term. Landlord shall not have any obligation to repair,
               -----------                                                   
reconstruct or restore the Premises during the last twelve (12) months of the
term of this Lease or any extension thereof, as a result of any damage to the
Premises if the cost of any such repair, reconstruction, or restoration as
reasonably estimated by the Landlord exceeds the then Monthly Rental.  If
Landlord elects not to repair the Premises of the Building pursuant to this
Section 10.4, Tenant may elect to terminate this Lease within thirty (30) days
of receipt of Landlord's notification of its election not to repair pursuant to
this Section 10.4.  If Tenant elects to terminate this Lease as provided in this
Section, this Lease shall terminate thirty (30) days following the election by
Tenant to terminate this Lease.  If Tenant does not elect to terminate this
Lease in such thirty (30) day period, the rent and other expenses payable by
Tenant shall not abate, Landlord may repair the Premises at Tenant's cost and
expense, and Tenant shall deposit with Landlord in advance an amount estimated
by Landlord as the cost of such repair.

     11. CONDEMNATION.
         ------------ 

         11.1  The term of this Lease shall terminate as to the portion of the
Premises taken or condemned by any authority under the power of eminent domain
or transferred by Landlord by agreement with such authority under threat of
condemnation, with or without any condemnation action being instituted, as of
date such authority requests possession of such portion of the Premises.  The
Monthly Rental shall be adjusted in the proportion that the square footage of
the portion of the Premises taken bears to the total square footage of the
Premises prior to such taking.  Tenant shall not be entitled to any
compensation, allowance, claim, or offset of any kind against the Landlord or
any condemning authority, as damages or otherwise, by reason of being deprived
of the Premises or by the termination of this Lease, except that Tenant shall be
entitled to such portion of any separate award for any improvements to the
premises paid for by Tenant in an amount not to exceed the unamortized cost of
such improvements with such costs amortized over the term of this Lease without
reference to any unexercised options.  Any portion of the Building other than
the Premises taken by eminent domain or dedicated to public use shall upon such
taking or dedication be excluded from the area over which Tenant is granted
rights hereunder, and this Lease shall continue in full force and effect without
any reduction in rental.

                                       11

     12.  ASSIGNMENT, SUBLETTING, AND RECAPTURE.
          ------------------------------------- 

          12.1  Consent Required.  Tenant shall deliver to Landlord promptly
                ----------------                                            
following execution an executed copy of any assignment, sublease, or agreement
relating to the Premises, regardless of whether or not such assignment,
sublease, or agreement is permitted by this Lease or requires Landlord's
consent.  Tenant shall not assign, sublease or otherwise transfer by operation
of law or otherwise this Lease or any interest herein without the prior written
consent of Landlord.  If Tenant desires at any time to assign or otherwise
transfer this Lease or sublease all or a portion of the Premises, it shall first
notify Landlord of its desire to do so and shall submit in writing to Landlord:
(i) the name of the proposed assignee or sublessee, (ii) the nature of the
proposed assignee's or sublessee's business to be carried on in the Premises,
(iii) a copy of the proposed assignment or sublease and any other agreements to
be entered into concurrently with such assignment or sublease, and (iv) such
financial information as Landlord may reasonably request concerning the proposed
assignee or sublessee. Landlord may condition its consent to any assignment or
sublease on the execution by such assignee or sublessee of a written assumption
by such assignee or sublessee of the obligations of Tenant under this Lease.  A
transfer of control of Tenant shall be deemed an assignment of this Lease and
shall be subject to all of the provisions of this Section. Tenant shall pay to
Landlord a reasonable fee and Landlord's expenses in reviewing such proposed
assignment or sublease.  Landlord shall respond to Tenant's request to assign or
sublease this Lease in a timely manner.  This Lease may not be assigned or
sublet without complying with the provisions of this Section in reliance on any
law relating to bankruptcy or debtor's rights generally unless adequate
assurance of future performance is provided Landlord including adequate
assurance of the source of rent and other expenses due under this Lease for the
entire term of this Lease and unless the assignee or sublessee and the proposed
use of the Premises by the assignee or sublessee are consistent with the type of
other tenants in the Building and the use by such tenants of their Premises.

         12.2  Prohibitions.   Partial assignments of Tenant's interest in this
               ------------                                                    
Lease as prohibited.  Any sale, assignment, encumbrance or other transfer of
this Lease and any subleasings or occupation of the Premises which does not
comply with the provisions of this Section shall be void and shall be a default
under this Lease.

         12.3  Payments to Landlord.  Tenant shall pay to Landlord promptly
               --------------------                                        
following receipt the amount by which the value of any consideration received by
Tenant from any such assignments exceeds Tenant's unamortized cost of tenant
improvements in the Premises.  Tenant shall pay to Landlord promptly following
receipt the amount by which all sublease rental and other payments received by
Tenant from any subtenant or any other person occupying any portion of the
Premises exceeds the total of the rental or other amounts payable by Tenant
pursuant to Section 4 for the portion of the Premises subleased with the rental
or other amounts payable by Tenant for the Premises allocated on the basis of
square footage.   The provisions of this Section

                                       12
<PAGE>
 
shall apply regardless of whether or not such assignment, subleasing or
occupation is made in compliance with the terms of this Lease. Any payments made
to Landlord pursuant to this Section, or Landlord's acceptance or endorsement
thereof, shall not constitute a consent to any assignment, subleasing or
occupation or cure any default under this Lease.

         12.4 Recapture. If Tenant requests Landlord's consent to any assignment
              ---------
or sublease of this Lease, Landlord shall have the right, to be exercised by
giving written notice to Tenant within thirty (30) days of receipt by Landlord
of the information concerning such assignment or sublease required by Section
12.1 to terminate this Lease effective as of the date Tenant proposes to assign
this Lease or sublease all or a portion of the Premises. On termination of this
Lease by Landlord pursuant to this Section, Landlord shall pay to Tenant the
unamortized cost of any tenant improvements to the Premises paid by Tenant, with
such costs amortized over the term of this Lease without reference to any
unexercised options. Landlord's right to terminate this Lease on assignment or
sublease shall not terminate as a result of Landlord's consent to the assignment
of this Lease or sublease of all or a portion of the Premises, or Landlord's
failure to exercise this right with respect to an assignment or sublease.

         12.5  No Release.   Landlord's consent to any sale, assignment,
               ----------                                               
encumbrance, subleasing, occupation or other transfer shall not release Tenant
from any of Tenant's obligations hereunder or be deemed to be a consent to any
subsequent assignment, subleasing or occupation.  The collection or acceptance
of rent or other payment by Landlord from any person other than Tenant shall not
be deemed the acceptance of any assignee or subtenant as the Tenant hereunder or
a release of Tenant from any obligation under this Lease.  If any assignee,
sublessee or successor of Tenant defaults in the performance of any obligation
under this Lease, Landlord may proceed directly against Tenant without the
necessity of exhausting any remedies against such assignee, sublessees or
successors.  Landlord may consent to subsequent assignments or subleasing of
this Lease or amendments or modifications of this Lease with the assignee,
sublessees or successors of Tenant without notifying Tenant or such assignee,
sublessee or successors and without obtaining their consent and such action
shall not relieve Tenant or such assignee, sublessee or successors of any
liability under this Lease.

     13.  DEFAULT AND REMEDIES.
          -------------------- 

          13.1  Events of Default.  The occurrence of any one or more of the
                -----------------                                           
following events shall constitute an Event of Default: (i) the failure by Tenant
to make any payment of rent or any other payments required to be made by Tenant
under this Lease when due if such failure continues for ten (10) days after
written notice by Landlord to Tenant of such failure; (ii) the failure by Tenant
to observe or perform any of the provisions of this Lease to be observed or
performed by the Tenant if such failure continues for a period of ten (10) days,
or such other period if this Lease specifically provides a different period for
a particular failure, after written notice by Landlord to

                                       13
<PAGE>
 
Tenant of such failure, provided, however, that with respect to any failure
which cannot reasonably be cured within ten (10) days, an Event of Default shall
not be considered to have occurred if Tenant commences to cure such failure
within such ten (10) day period and continues to proceed diligently with the
cure of such failure; (iii) the failure by Tenant to pay its obligations as they
become due; the making of any general assignment or general arrangement for the
benefit of creditors by Tenant, or the filing by or against Tenant of a petition
to have Tenant adjudged bankrupt or a petition for reorganization or arrangement
under bankruptcy law or law affecting creditor's rights unless, in the case of a
petition filed against Tenant, such petition is dismissed within sixty (60)
days; the appointment of a trustee or a receiver to take possession of the
Premises where possession is not restored to Tenant within thirty (30) days; or
the attachment, execution or other judicial seizure of substantially all of
Tenant's assets located at the Premises or of Tenant's interest in this Lease,
where such seizure is not discharged in thirty (30) days; or (iv) Tenant
transfers or agrees to transfer this Lease or possession of all or any portion
of the Premises without Landlord's prior written consent.

         13.2 Remedies. On the occurrence of an Event of Default, Landlord may
              --------
at any time thereafter, with or without notice or demand and without limiting
Landlord in the exercise of a right or remedy which Landlord may have by reason
of such default or breach, do the following:

     (i) Landlord may elect to continue the term of this Lease in full force and
effect and not terminate Tenant's right to possession of the Premises, in which
event Landlord shall have the right to enforce any rights and remedies granted
by this Lease or by law against Tenant, including, without limitation, the right
to collect when due rental or other sums payable hereunder.  Landlord shall not
be deemed to have elected to terminate this Lease unless Landlord gives Tenant
written notice of such election to terminate.  Landlord's acts of maintenance or
preservation of the Premises or efforts to relet the Premises shall not
terminate this Lease.

     (ii) Landlord may elect by written notice to Tenant to terminate this Lease
at any time after the occurrence of an Event of Default, and in such event
Landlord may, at Landlord's option, declare this Lease and Tenant's right to
possession of the Premises terminated, re-enter the Premises, remove Tenant's
property therefrom and store it for Tenant's account and at Tenant's expense
(but Landlord shall not be required to effect such removal), eject all persons
from the Premises and recover damages from Tenant as hereinafter provided.  Any
such re-entry shall be permitted by Tenant without hindrance.  Landlord shall
not thereby be liable in damages for such re-entry or be guilty of trespass,
forcible entry or unlawful detainer.  If Landlord elects to so terminate this
Lease and Tenant's right to possession or if this Lease and Tenant's right to
possession are terminated by operation of law, such termination shall cancel all
Tenant's options, if any, to extend or renew the term of this Lease.

                                       14
<PAGE>
 
     (iii)  Landlord may notify any subtenant of the Premises of the existence
of an Event of Default by Tenant in writing and thereafter all rent or other
amounts due from any subtenant of the Premises shall be paid to Landlord and
Landlord shall apply such rent or other amounts in payment of the amounts due
from Tenant under this Lease. The delivery of such notice to any subtenant and
the collection of such rent or other amounts by Landlord shall not terminate
this Lease.

         13.3 Damages on Termination. On Termination of this Lease by reason of
              ----------------------
Tenant's breach, Landlord may recover as damages from Tenant, in addition to all
other remedies available, but without repeating or otherwise duplicating any
remedy heretofore granted to Landlord, an amount equal to the present value,
discounted by the then current discount rate at the Federal Reserve Bank of
Richmond, of the difference between the rent or other sums payable by Tenant to
Landlord for the term of this Lease after the date of termination, as if this
Lease were still in effect, and the reasonable rental value of the Premises for
such period as proved by Tenant. On termination of this Lease by reason of
Tenant's breach, Landlord may also recover as damages from Tenant all of the
rent or other sums payable by Tenant pursuant to this Lease after the date of
termination, as if this Lease were still in effect, until such time as Landlord
has released the entire Premises, reduced by any rent or other payments which
Landlord receives for the use of any portion of the Premises prior to releasing
the entire Premises. On termination of this Lease by reason of Tenant's breach,
Landlord may also recover as damages from Tenant that portion of any leasing
commissions paid or payable by Landlord applicable to the unexpired term of this
Lease and all costs incurred in releasing the Premises including advertising
costs, the costs of refurbishment and alterations of the Premises and the cost
of any concessions which the Landlord gives to release the Premises. If Landlord
releases the Premises following a termination by reason of Tenant's breach, the
rent charged by Landlord on such releasing shall be deemed to be the rental
value of the Premises for the purpose of calculation of the damages which
Landlord may recover from Tenant.

         13.4 Late Charge. If Tenant fails to make any payment of rent, expenses
              -----------
or other amounts required of Tenant under this Lease within ten (10) days of the
date such amount is due as set forth in this Lease, then, in addition to any
other amounts recoverable by Landlord hereunder, Tenant shall pay Landlord a
late charge in an amount equal to $0.06 for each dollar past due. If Tenant
fails, on three (3) separate occasions, to make any payment of rent, expenses or
other amounts required of Tenant under this Lease within three (3) days of the
date each such payment is due, then for the remainder of the Lease Term, Tenant
shall pay a late charge in an amount equal to $0.06 for each dollar past due if
Tenant thereafter fails to pay any payment of rent or other amount required
under this Lease promptly when due. Such late charge shall be due
notwithstanding the fact that no notice is given by Landlord to Tenant of such
failure to pay. Notwithstanding the foregoing, if on three (3) separate
occasions Tenant has received notice from Landlord that it has failed to pay
rent, expenses or other amounts promptly when due, Tenant shall pay Monthly
Rental for the balance of the term of this

                                       15
<PAGE>
 
Lease on a quarterly basis, in advance, on the first day of each such quarter.
Landlord and Tenant agree that it would be extremely difficult and impractical
to fix the actual damages sustained by Landlord for such default and that the
late charge or quarterly rental payment set forth in this Section is a
reasonable estimate of such damages at this time.  Landlord anticipates that
such damage would include the administrative costs and expenses, the cost of
arranging for borrowed funds and attorneys' fees.  The late charge provided in
this Section shall be the sole damages which Landlord may recover from Tenant
for the delay by Tenant in making any payment within ten (10) days from the date
such payment is due until thirty (30) days after the date such payment is due,
but this Section shall not limit Landlord's right to recover any other amount
due pursuant to this Lease, Landlord's damages equivalent to the amount of the
rent or other payments if this Lease is terminated, Landlord's damages or costs
for Tenant failure to pay for a period beyond thirty (30) days from the date
such payment is due, Landlord's cost and expense in connection with any
litigation and Landlord's right to any other remedy such as terminating this
Lease, recovering possession of the Premises or injunctive relief.

         13.5 Past Due Obligations. All amounts which Tenant is obligated to pay
              --------------------
Landlord pursuant to this Lease or when due shall bear interest at the maximum
interest rate chargeable by law, not to exceed twenty percent (20%) per annum
from the due date until paid, unless otherwise specifically provided herein. If
a late charge is due with respect to such amount pursuant to Section 13.4, such
interest shall commence to accrue thirty (30) days following the date such
amount is due. The payment of such interest shall not excuse or cure any default
by Tenant under this Lease.

         13.6 Non-Exclusive Remedies. The remedies of Landlord set forth in this
              ----------------------
Section 13 shall not be exclusive, but shall be cumulative and in addition to
all rights and remedies now or hereafter provided or allowed by law or equity,
including, but not limited to, the right of Landlord to seek and obtain an
injunction and the right of Landlord to damages in addition to those specified
herein, except that the provisions of Section 13.4 shall limit Landlord's right
to damages as specified therein. Tenant hereby expressly waives any and all
rights of redemption granted by or under any present or future law if Tenant is
evicted or dispossessed for any cause or if Landlord obtains possession of the
Premises by reason of the breach by Tenant of any of its obligations under this
Lease. Tenant hereby expressly waives (i) the service of any notice in writing
of intention to re-enter or to institute legal proceedings to that end and (ii)
any right which Tenant may have to a jury trial in connection with any such
legal proceedings.

         13.7 General Landlord Cure Provision. In the event Tenant defaults in
              -------------------------------
the performance of any of the terms, covenants, or conditions of this Lease, or
fails to comply with any of the laws, statutes, ordinances, rules, orders,
regulations or requirements of any governmental authority, then in such case
Landlord shall have the immediate right, in addition to all rights and remedies
outlined in this Section 13, to cure such default or noncompliance for the
account of and at the cost and expense of Tenant,

                                       16
<PAGE>
 
and the full amount so expended by Landlord, plus interest at the rate of
fifteen percent (15%) per annum thereon, shall immediately be due and owing by
Tenant to Landlord as additional rent hereunder.

     14.  ADDITIONAL RIGHTS OF LANDLORD.
          ----------------------------- 

          14.1 Entry by Landlord. Landlord and its agents and employees shall
               -----------------
have the right to enter the Premises at all times, to examine the same, to make
such maintenance and repairs of the Premises and such maintenance, repairs,
alterations, decorations, additions and improvements to other portions of the
Building as Landlord requires and to show the Premises at reasonable times to
prospective tenants during the last six (6) months of the term of this Lease.
Landlord may erect, use and maintain pipes and conduits in and through the
Premises provided such pipes and conduits do not detract from the appearance of
the Premises. Landlord shall take reasonable precautions to minimize the
disruption to Tenant of any entry to the Premises by Landlord as provided in
this Section.

         14.2 Building Planning. Landlord shall have the right at any time
              -----------------
during the term of this Lease, upon giving Tenant sixty (60) days notice in
writing, to provide and furnish Tenant with like space elsewhere in the Building
of approximately the same size and area as the Premises and to remove and place
Tenant in such new space at Landlord's sole cost and expense. On such
relocation, the terms and conditions of this Lease shall remain in full force
and effect, save and except that the Premises shall be in such new location
within the Building, a revised Exhibit "A" shall become part of this Lease and
shall reflect the location of the new space, Section 1 of this Lease shall be
amended to include and state all correct data as to the new space, and the
Monthly Rental shall be reduced, but not increased, by the reduction of the Area
of Premises, if any, on such relocation. However, if the new space does not meet
with Tenant's approval, Tenant shall have the right to cancel this Lease upon
giving Landlord thirty (30) days written notice within ten (10) days of receipt
of Landlord's notification.

         14.3  Transfer by Landlord.  Landlord may transfer its interest in the
               --------------------                                            
Premises and this Lease without the consent of Tenant, at any time and from time
to time.  The obligations of Landlord pursuant to this Lease shall be binding
upon Landlord and its successors only during their respective period of
ownership except that Landlord and its successors shall be relieved of their
obligation to refund security deposits and other funds to Tenant which they have
received from Tenant or a predecessor Landlord only to the extent they transfer
such amounts to their respective transferees.  In addition, Landlord may lease
any portion of the Building to others on such terms and for such purposes as
Landlord considers appropriate and may terminate or modify leases with others
for any portion of the Building without any obligation to Tenant and without
relieving Tenant of any obligation under this Lease.

                                       17
<PAGE>
 
         14.4  Default by Landlord.  Landlord shall not be liable to Tenant if
               -------------------                                            
Landlord is unable to fulfill any of its obligations under this Lease if
Landlord is prevented, delayed or curtailed from so doing by reason of any cause
beyond Landlord's reasonable control.  Landlord shall not be in default unless
Landlord fails to perform obligations required of Landlord within a reasonable
time, but in no event later than thirty (30) days after written notice by Tenant
to Landlord, specifying Landlord's failure to perform such obligation; provided,
however, that if the nature of Landlord's obligation is such that more than
thirty (30) days are required for performance, then Landlord shall not be in
default if Landlord commences performance within such thirty (30) day period and
thereafter diligently prosecutes  its efforts to satisfy such obligation.
Tenant may not offset against any rent or other amount due from Tenant under
this Lease any amount due or claimed to be due to Tenant from Landlord whether
arising pursuant to this Lease or otherwise.  Any notice to Landlord by Tenant
of Landlord's default under this Lease shall also be concurrently provided by
registered or certified mail, to any holder of a mortgage or similar security
instrument covering the Premises, whose address shall have been furnished to
Tenant ("Mortgagee Notice").  The Mortgagee's Notice shall offer such  mortgagee
a reasonable opportunity to cure the default, including the time to obtain
possession of the Premises by power of sale or judicial foreclosure, if such
action should be necessary to cure Landlord's default.

         14.5 Subordination. This Lease is subject and subordinate to all ground
              -------------
or underlying leases, mortgages and deeds of trust which now affect the Building
or any part of the Building and to all renewals, modifications, consolidations,
replacements and extensions thereof. This Lease may, at the option of Landlord,
be subordinate to any ground or underlying leases, mortgages, deeds of trust or
other lien which may hereafter affect the Building or any part thereof and
Tenant will execute and deliver upon the demand of Landlord from time to time
any and all instruments desired by Landlord, subordinating, in the manner
requested by Landlord, this Lease to such lease, mortgage, deed of trust or
other lien, provided such lease, mortgage, deed of trust or lien provides that
in the event of termination of such lease or foreclosure of such mortgage, deed
of trust or lien, any successor to any interest of Landlord in the Building will
not disturb Tenant's possession of the Premises if Tenant attorns to such
successor as Landlord and otherwise performs its obligations under this Lease.
Tenant agrees that Tenant shall attorn to any Landlord under any ground lease
affecting the Building in the event of the termination or cancellation of such
ground lease or to any purchaser upon foreclosure or sale pursuant to any lien.

mortgage, deed or trust or other lien, any successor to any interest of Landlord
in the Building shall have no liability to repay to Tenant any security deposit
paid to any prior Landlord. Landlord may from time to time grant or declare such
restrictions or covenants as may be reasonably required by Landlord or adopt and
record such parcel maps, subdivision maps or condominium plans as may be
reasonably required by Landlord relating to all or any portion of the Building
and the provisions of all such documents shall be senior to this Lease and

interfere with the use of the Premises by Tenant as permitted by this Lease.
Tenant acknowledges the right of the holder of any first mortgage or other first
security interest in all or any part of the Building to subordinate its first
mortgage or other first security interest either in whole or in part to this
Lease.  Tenant agrees at any time, and from time to time, upon not less than
five (5) days notice, to execute, acknowledge and deliver to such holder the
Tenant's agreement to such subordination in such form as such holder may
require.  Without limiting the generality of the foregoing, the form of
subordination of the first mortgage or other first security interest may provide
that it does not affect, is not applicable to, and expressly excludes the
following: (i) the prior right, claim and lien of the first mortgage or first
security interest in, to and upon any award or other compensation heretofore or
hereafter to be made for any taking by eminent domain of any part of the
Building, and to the right of disposition thereof in accordance with the
provisions of the first mortgage or first security interest; (ii) the prior
right, claim and lien of the first mortgage or first security interest in, to
and upon any proceeds payable under all policies of fire and rent insurance upon
the Building, or any part thereof, and as to the right of disposition thereof in
accordance with the terms of the first mortgage or first security interest; and
(iii) any lien, right, power or interest, if any, which may have arisen or
intervened in the period between the recording of the first mortgage or first
security interest and the execution of this Lease, or any lien or judgment which
may arise at any time under the terms of this Lease.

the endorsement or statement on any check or any letter accompanying any check
or other payment shall not be deemed an accord or satisfaction or a waiver of
any obligation of Tenant regardless of whether or not Landlord had knowledge of
any breach of such obligation.  Failure to insist on compliance with any of the
terms, covenants or conditions hereof shall not be deemed a waiver of such
terms, covenants or conditions nor shall any waiver or relinquishment of any
