                            ------------------------
 
   
     Doctors Health System, Inc., a Maryland corporation (the "Company"),
directly or through agents designated from time to time, may offer and issue
from time to time in connection with the acquisition of medical practices or
other transactions with physicians one or more of the following types of its
securities: (i) shares of its Class B common stock, par value $0.01 per share
("Class B Common Stock"); or (ii) Options to purchase Class B Common Stock
("Options," and collectively with the Class B Common Stock, the "Securities").
The Company will not receive cash proceeds in connection with the issuance of
the Securities.
    
 
     The Securities offered pursuant to this Prospectus may be issued in one or
more series, in amounts, at prices and on terms to be determined at the time of
the offering of each such series.
 
   
     It is anticipated that the acquisition of the medical practices will
involve the receipt by the Company primarily of enumerated tangible assets of
such practices and/or contractual rights. The consideration for acquisitions and
contractual rights will consist of shares of Class B Common Stock, cash,
Options, assumption of liabilities or a combination of some or all of them, as
determined from time to time by negotiations between the Company and the
physicians or physician groups operating such practices. In addition, such
physicians may enter into employment agreements and IPA participation
agreements, pursuant to which the Company may also issue Securities.
    
 
   
     The terms of a transaction are determined by negotiations between the
Company's representatives and physicians. Factors taken into account in such
transactions include the established size, quality and reputation of the
practice and the Company's estimate of the market value of the Class B Common
Stock. It is anticipated that shares of Class B Common Stock issued will, in
most cases, be valued at a price reasonably related to the current market value
of the Class B Common Stock, either at the time the terms of a transaction are
tentatively agreed upon, or at or about the time of closing, or during the
period or periods prior to delivery of the shares.
    
 
   
     The specific terms of each offering of Securities in respect of which this
Prospectus is being delivered are set forth in an accompanying Prospectus
Supplement (each, a "Prospectus Supplement") relating to such offering of
Securities. Such specific terms include, without limitation, to the extent
applicable (1) in the case of the Options, the Class B Common Stock for which
each such Option is exercisable, and the exercise price, duration,
detachability, restrictions, and call provisions of each such Option; and (2) in
the case of any offering of Securities, to the extent applicable, the offering
price or prices, and certain Federal income tax consequences. The resale or
transfer of the Securities will be subject to certain restrictions. See
"Description of Capital Stock."
    
 
     It is not expected that underwriting discounts or commissions will be paid
by the Company except that finders fees may be paid to persons from time to time
in connection with specific acquisitions. The Company may issue all or a portion
of any offering of its Securities through agents or directly to other
purchasers. The related Prospectus Supplement for each offering of Securities
sets forth the name of any agents involved in the issuance of such Securities
and any applicable fee, commission or indemnification arrangement with any such
party. See "Use of Proceeds."
 
     This Prospectus may not be used to consummate sales of Securities unless
accompanied by a Prospectus Supplement. The delivery in any jurisdiction of this
Prospectus together with a Prospectus Supplement relating to specific Securities
shall not constitute an offer in such jurisdiction of any other Securities
covered by this Prospectus but not described in such Prospectus Supplement.
 
   
     The Securities offered pursuant to this Prospectus will be subject to
significant contractual restrictions or transfer. Further, it is not currently
anticipated that any of the Securities will be listed on an exchange or other
public market. Accordingly, trades in the Securities may be subject to various
regulatory structures which could severely limit the liquidity of the
Securities.

                               PROSPECTUS SUMMARY

     THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY, AND SUBJECT TO, THE
MORE DETAILED INFORMATION AND FINANCIAL STATEMENTS (INCLUDING THE NOTES THERETO)
CONTAINED ELSEWHERE IN THIS PROSPECTUS. UNLESS OTHERWISE DEFINED HEREIN,
CAPITALIZED TERMS USED IN THIS SUMMARY HAVE THE RESPECTIVE MEANINGS ASSIGNED TO
THEM ELSEWHERE IN THIS PROSPECTUS. POTENTIAL INVESTORS SHOULD READ THIS
PROSPECTUS CAREFULLY IN ITS ENTIRETY.
 
THE COMPANY
 
   
     Doctors Health System, Inc., a Maryland corporation ("DHS" or the
"Company") was incorporated in June of 1994 and commenced operations in February
of 1995. The Company is the substitute corporate entity formed to reorganize the
business of Baltimore Medical Group, P.A. ("BMGPA"). BMGPA was incorporated in
January of 1993. The Company's executive offices are located at 10451 Mill Run
Circle, Owings Mills, Maryland 21117, telephone (410) 654-5800.
    
 
   
     The Company develops and consolidates individual and groups of internists,
pediatricians and family practitioners ("primary care physicians" or "PCPs"),
specialist physicians, hospitals and other health care providers into primary
care-driven, comprehensive managed care health delivery networks. Through
contracts with PCPs, specialists, hospitals and other health care providers, the
Company designs its networks: (i) to manage the provision of quality medical
services to patients; (ii) to furnish Network Physicians with access to managed
care contracts and related services; (iii) to establish a single source of
access for health maintenance organizations ("HMOs") and other Payors to a
comprehensive range of health care providers; and (iv) to offer patients a
comprehensive range of health care services. Currently, the Company is focusing
on the development and establishment of its networks in the Baltimore and
Washington metropolitan area and surrounding regions.
    
 
   
     As of October 4, 1996, the Company had approximately 694 Network Physicians
in six regional networks throughout the state of Maryland, including
approximately 176 PCPs, 95 obstetrician/gynecologists, and 423 specialist
physicians. Of these, 90 were Equity Physicians, of which 57 had transferred
their practice assets to the Company or one of its subsidiaries, 17 had entered
into binding agreements to complete such transactions, and 16 were subject to a
letter of intent with respect to an acquisition which the Company believes will
be completed by December 31, 1996. While primary care-based, the Company
encourages its Core Medical Groups to develop into multi-specialty group
practices and provides or arranges financing and other resources to enable such
Core Medical Groups to develop into diversified multi-specialty practices. The
Company also provides to Network Physicians certain patient care management,
administrative and financial services, including information systems,
contracting for and providing facilities, equipment and other goods. See
"Business--Development of Integrated Health Care Delivery System."
    
 
   
     The Company offers medical groups and independent physicians a variety of
methods of participating in the Company's Integrated Health Care Delivery
System. The Company may acquire certain medical practice assets or certain
contracting rights, either for cash or for Securities, or by execution of a
variety of Independent Physician Association ("IPA") participation agreements.
The Company typically enters into Physician Services Organization Agreements
("PSO Agreements") with the Core Medical Groups, pursuant to which the Company
provides care management, managed care contracting and related business
management services.
    
 
   
     The Company's strategy is to capitalize upon changes in the health care
industry by: (i) establishing networks of primary care physicians and specialist
physicians to integrate a full spectrum of health care providers into one or
more high quality, cost-effective health care delivery networks; (ii)
transitioning the patients of Network Physicians to the Company's Global
Capitated Contracts; (iii) providing HMOs and other Payors with a single source
of access to geographically proximate networks of physicians and other
providers; (iv) focusing on obtaining Global Capitated Contracts and operating
profitably under a capitated reimbursement system; (v) allowing physicians
greater access to managed care, while relieving physicians of some of the
administrative responsibilities and economic risks of providing managed care
services; (vi) effectively managing the cost and quality of providing care
through the use of sophisticated information systems and a broad range of
practice management and administrative services; and (vii) expanding
aggressively by recruiting additional physicians to networks that have already
been established and by establishing additional networks. See

                                  RISK FACTORS
 
     IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, PROSPECTIVE
INVESTORS SHOULD CONSIDER THE FACTORS LISTED BELOW IN EVALUATING AN INVESTMENT
IN THE SECURITIES OFFERED HEREBY.
 
LIMITED OPERATING HISTORY; LOSSES
 
   
     The Company was incorporated in June of 1994 and commenced operations as
DHS in February of 1995. The Company is the substitute corporate entity formed
to reorganize the business of Baltimore Medical Group, P.A. ("BMGPA"). BMGPA was
incorporated in January of 1993. Accordingly, the Company has a limited
operating history. For the year ended June 30, 1996, the Company recorded a net
loss of approximately $6.6 million. The Company is likely to record a net loss
for the year ending June 30, 1997, and at June 30, 1996 had an accumulated
deficit of approximately $9.1 million. There can be no assurance that future
operating losses would not have a material adverse effect on the operating
results and financial condition of the Company. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Results of
Operations."
    
 
LIQUIDITY; RESTRICTIONS ON FINANCING
 
   
     Until the Company and its Payors attract an adequate number of Capitated
Lives in the Company's Global Capitated Contracts, the Company expects to incur
operating losses and experience negative operating cash flows. The Company
believes that its cash on hand and the balance remaining available under the
NationsBank Credit Facility will be sufficient to meet the Company's immediate
working capital needs. However, in the event that the Company and its Payors
either have not attracted an adequate number of Capitated Lives in Global
Capitated Contracts sufficient to offset the Company's operating expenses, or
the Company has not secured a substantial amount of additional capital, the
Company's operating results and financial condition would be materially and
adversely affected. There can be no assurance that the Company will be able to
secure such additional capital, or that such capital, if available, will be on
terms favorable to the Company. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity, Cash Flow and Capital
Resources--Subsequent Events."
    
 
   
     The Company's Series A, Series B and Series C Preferred Stock Directors
have the right under the Company's constituent documents to approve the
incurrence by the Company of indebtedness (including both borrowed money and
capitalized leases) in excess of $1 million beyond the amount budgeted by the
Company from time to time. In addition, the Company's ability to conduct equity
financings may be affected by certain rights of consent of the holders of the
Company's Series A, Series B and Series C Preferred Stock. See "Description of
Capital Stock." There can be no assurance that such holders of Preferred Stock
will grant their consent to the terms of any such financings.
    
 
UNCERTAINTY OF STRATEGY; ACQUISITION RISKS
 
   
     The Company's strategy is based upon assumptions relating to the Company's
likely rate of growth of acquisitions of medical practices, the rate at which
capitated lives can be added to the Company's networks, the likely referral and
other business practices of physicians and health care institutions in the
Baltimore and Washington metropolitan area and surrounding regions, and
assumptions relating to the rate and character of reimbursement for services
provided through the various arrangements negotiated by the Company, including
the continued willingness of Payors to enter into risk sharing arrangements.
Certain of the Company's assumptions may prove to be incorrect, which could have
a material adverse effect on the operating results and financial condition of
the Company. Thus, no assurance can be given that the Company's strategy will be
successfully and profitably implemented.
    
 
   
     Further, the Company's strategy depends upon the successful recruitment of
physicians to join Core Medical Groups and Exclusive IPAs. There can be no
assurance that the Company will be able to grow in existing or new markets or
successfully identify, complete or integrate any acquisitions or IPA contracts.
The process of identifying suitable candidates, and proposing, negotiating and
implementing an economically feasible transaction with a physician group or
forming or managing a physician network, is lengthy and complex. The Company's
strategy involves focusing the development of its Integrated Health Care
Delivery System in the Baltimore and Washington metropolitan area and
surrounding regions. Accordingly, the Company is subject to and may be adversely
affected by any changes in laws and regulations in these areas pertaining to its
business. See "Business--Regulation." Further, currently substantially all of
the Company's net revenues are used to pay for costs of and in support of the
Core Medical Groups and Network Physicians. Thus, the Company's ability to
generate any profit is dependent upon its ability to transition its Network
Physicians and other providers in the Company's provider networks away from
unmanaged fee-for-service compensation arrangements and into a profitable
Managed Care
    
 
                                       6
 
<PAGE>
   
environment. The failure of the Company to execute its strategy effectively
could have a material adverse effect on the operating results and financial
condition of the Company. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
    
 
DEPENDENCE ON MANAGED CARE CONTRACTS
 
   
     The profitability of the Company depends on securing and maintaining
contractual relationships with Managed Care plans and other Payors and
successfully managing the expenses involved in the provision of services under
those contracts without sacrificing the quality of medical care. Such medical
expenses are subject to adverse selection and other utilization risks and are
not otherwise within the Company's or the Core Medical Groups' control. The
inability of the Company and its Network Physicians to obtain such contracts or
successfully manage such expenses could have a material adverse effect on the
operating results and financial condition of the Company. In addition, the
success of Payors depends substantially on their ability to reduce, or
significantly restrain the growth of, spending for health care services.
Accordingly, there is a risk that the Company will not be able to obtain or
maintain the numbers of Managed Care contracts presently contemplated or that,
if such contracts are obtained, payments from such Payors will decrease over
time, either of which could have a material adverse effect on the operating
results and financial condition of the Company. Further, the coverage of the
Managed Care plans with which the Company contracts may be limited to the State
of Maryland, the District of Columbia, Virginia or other limited geographic
regions. There can be no assurance that the coverage of such Managed Care plans
will extend beyond such areas. Finally, the Company's contracts with Payors are
generally for one year and may be terminated earlier upon notice. There can be
no assurance that Managed Care contracts will not be terminated. The loss of any
Payors or the failure to retain such Payors' Enrollees could have a material
adverse effect on the operating results and financial condition of the Company.
    
 
ENROLLMENT IN MEDICARE MANAGED CARE PLANS
 
   
     The Company has entered and will enter into Full Risk Contracts and Global
Capitated Contracts with HMOs and other Managed Care Plans covering Medicare
patients. The Company's profitability is highly dependent on the Company's
ability to attract existing patients and new Medicare patients who enroll in the
Medicare Managed Care contracts with licensed HMOs pursuant to Global Capitated
Contracts with the Company. See "Business--Strategy--Medicare Managed Care." The
Company's strategy depends on successful joint marketing efforts by HMOs and the
Company and the willingness of Medicare patients to enroll in Managed Care
plans. There can be no assurance that the Company will be able to successfully
attract a sufficient number of Medicare patients into Medicare Managed Care
plans under contract with the Company or that such patients can be converted in
accordance with the Company's strategy. The failure of the Company to attract a
sufficient number of Medicare patients to Medicare Managed Care plans could have
a material adverse effect on the operating results and financial condition of
the Company.
    
 
   
RISKS OF CHANGES IN PAYMENT FOR MEDICAL SERVICES
    
 
   
     The profitability of the Company may be adversely affected by Medicare and
Medicaid regulations, cost containment decisions of Payors and other payment
factors over which the Company has no control. The Federal Medicare program has
undergone significant legislative and regulatory changes in the reimbursement
and fraud and abuse areas, including the adoption of the resource-based relative
value scale ("RBRVS") schedule for physician compensation under Medicare, which
may have a negative impact on the Company's revenue. Efforts to control the cost
of health care services are increasing. Future profitability in the changing
health care environment, with differing methods of payment for medical services,
is likely to be affected significantly by management of health care costs,
pricing of services and agreements with Payors. Because the Company derives its
revenues from the revenues generated by Network Physicians, further reductions
in payments to physicians generally or other changes in payment for health care
services could have a material adverse effect on the operating results and
financial condition of the Company.
    
 
   
     HCFA recently announced its intention to conduct an experimental pilot
program designed to reduce expenditures under Medicare Managed Care plans in
selected areas, including the Baltimore metropolitan area. The effect of any
such experimental program, if implemented, cannot be predicted, but could have a
material adverse effect on the operating results and financial condition of the
Company. See "Business--Regulation."
    
 
DEPENDENCE OF THE COMPANY ON CORE MEDICAL GROUPS AND IPAS
 
   
     The Company enters into Managed Care contracts with Payors pursuant to
which the Company agrees to arrange for the delivery of medical services to
Enrollees in exchange for Managed Care compensation. The Company does not engage
in the
    
 
                                       7
 
<PAGE>
   
practice of medicine and will be largely dependent upon medical services
provided by Network Physicians for its revenues. The success of the Company
initially will be dependent in large part upon its ability to attract Network
Physicians to join Core Medical Groups or to participate in IPA arrangements
with the Company, and upon the Core Medical Groups' and the Network Physicians'
ability to deliver high quality patient care in a cost-efficient manner. There
can be no assurance that the Company will be able to attract and retain the
requisite number of PCPs and specialist physicians, or that such physicians will
deliver high quality medical services profitably, either of which could have a
material adverse effect on the operating results and financial condition of the
Company.
    
 
   
     With respect to Core Medical Groups, the Company enters into a PSO
Agreement which obligates the Core Medical Group to contract solely and
exclusively with the Company for 30 years (with automatic ten-year renewals) for
all managed care contracts, and for the provision of all of the non-medical
services, including provision of facilities, equipment, supplies and other goods
and assets, used by the Core Medical Groups and their employee physicians to
engage in the practice of medicine. See "Business--Development of Integrated
Health Care Delivery System--Focus on Primary Care Physicians." There can be no
assurance that the Company will be able to meet its contractual obligations to
the Core Medical Groups in a manner that is reasonably acceptable to the Core
Medical Groups. A failure of the Company to meet its contractual obligations
could result in the termination of such arrangements, which could have a
material adverse effect on the operating results and financial condition of the
Company.
    
 
COMPETITION
 
     The health care industry is highly competitive and is subject to continuing
changes in how services are provided and how health care providers are selected
and paid. Generally, the Company competes with any entity that contracts with
Payors for the provision of prepaid health services (including but not limited
to PHOs, IPAs and independent private practice physicians) and with hospitals
and Payors which own or operate health care delivery systems. The Company also
competes with other companies, including entities such as managed care
organizations which provide managed care and other services to health care
providers. Such competitors may include local, regional and national entities.
 
   
     Some of these companies provide traditional management services to primary
care, multi-specialty and specialty physician groups, while other companies
provide claims processing, utilization review and other more focused management
services. Some competitors are significantly larger and better capitalized than
the Company and have access to greater resources, provide a wider variety of
services, have greater experience in providing health care management services
and have longer established relationships with buyers of such services than does
the Company. To the extent that health care reform measures or any other factors
make the provision of prepaid managed medical care an attractive market to other
potential participants, the Company may encounter increased competition.
Additionally, there is increased competition among a wide range of entities to
acquire or contract with physician practices. Such competition could increase
the cost of making such acquisitions and contracts and could endanger the
success of the Company's strategy of acquiring or contracting with PCPs in
selected markets. There can be no assurance that the Company will be able to
acquire or contract with a sufficient number of physician practices and thereby
compete favorably in contracting with Payors or to expand or maintain its
physician networks in existing or new markets. Any of the foregoing could have a
material adverse effect on the operating results and financial condition of the
Company.
    
 
DILUTION
 
   
     The Company contemplates that it will acquire additional medical practices
for existing Core Medical Groups and will organize additional Core Medical
Groups. The Company also contemplates contracting with additional physicians
through IPAs and other arrangements and compensating IPAs for recruiting their
IPA Participant Physicians to contract with the Company. The Company may issue
Securities in connection with any of such transactions. The Company may make
such acquisitions and contracts if it believes, in the exercise of its
discretion, that such acquisitions are beneficial, and without any requirement
that the Company's stockholders approve such transactions, all on terms as may
be negotiated by the Company. In addition, the Company intends to obtain
additional financing, some of which could result in dilution to the then
existing Stockholders. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity, Cash Flow and Capital
Resources--Subsequent Events."
    

   
     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, such issuances may be
dilutive to the then existing stockholders. Although the Company contemplates
that additional securities will be issued in the future, there can be no
assurance as to the number, if any, of new physicians, IPAs or investors who
will become stockholders of the Company.

INTANGIBLES
    
 
   
     As a result of the Company's acquisitions during 1995 and 1996, intangibles
increased from $1,287 as of June 30, 1995 to $2,387,150 as of June 30, 1996. The
Company's policy is to amortize intangibles over a 10 to 40 year period. The
intangibles acquired during fiscal 1995 and fiscal 1996 are being amortized over
20 years using the straight-line method in the Company's consolidated financial
statements. Such amortization is expected to significantly affect the Company's
profitability in the near term. In addition, the Company's future acquisitions
may generate additional intangibles. As required under generally accepted
accounting principles, the Company reviews the carrying value of intangibles at
each reporting period to determine if facts or circumstances exist which suggest
that intangibles may be impaired. If impairment is determined to have occurred,
intangibles will be adjusted downward. There can be no assurance that impairment
of intangibles with respect to the Company's acquisitions will not occur. Such
adjustment, if required, could have a material adverse effect on the operating
results and financial condition of the Company. See Note 3 to Notes to
Consolidated Financial Statements.
    
 
VOTING LIMITATIONS; RESTRICTIONS ON RESALE OF SECURITIES
 
   
     Each of the classes of Common Stock is entitled to elect a certain number
of the Company's directors and has its own particular voting requirements. The
holders of the Class A Common Stock are entitled to elect five of the Company's
18 directors (each a "Class A Director") by an affirmative vote of a plurality
of all votes cast at a meeting at which a quorum of Class A Common Stock is
present. The holders of the Class B Common Stock are entitled to elect eight of
the Company's 18 directors (each a "Class B Director") by an affirmative vote of
a plurality of all votes cast at a meeting at which a quorum of Class B Common
Stock is present. The holders of the Series A Preferred Stock are entitled to
elect two of the Company's 18 directors (each a "Series A Preferred Director")
by an affirmative vote of a plurality of all votes cast at a meeting at which a
quorum of Series A Preferred Stock is present. The holders of the Series B
Preferred Stock are entitled to elect two of the Company's 18 directors (each a
"Series B Preferred Director") by an affirmative vote of a plurality of all
votes cast at a meeting at which a quorum of Series B Preferred Stock is
present. Prior to the Company's 1998 annual meeting, the holders of the Series C
Preferred Stock are entitled to elect one of the Company's 18 directors (each a
"Series C Preferred Director") by an affirmative vote of a plurality of all
votes cast at a meeting at which a quorum of Series C Preferred Stock is
present. At the Company's 1998 annual meeting of stockholders, the number of
directors of the Company shall be increased to 19, and thereafter, the holders
of the Series C Preferred Stock will be entitled to elect two of the Company's
directors. Upon conversion of all of the Series A, Series B and Series C
Preferred Stock to Class C Common Stock, the holders of shares of Class C Common
Stock shall be entitled to elect five directors of the Company prior to the
Company's 1998 annual meeting and six directors thereafter (each a "Class C
Common Director"). Further, the Company must obtain the consent of the holders
of the Company's Series A, Series B and Series C Preferred Stock (collectively,
the "Preferred Stock") in connection with a variety of significant corporate
activities. All of the Company's stockholders (with the exception of employee
participants in the Company's Omnibus Stock Option Plan which, by its terms,
restricts in certain ways the resale of stock issued thereunder) are parties to
a Stockholders Agreement which governs a variety of matters, including voting as
to directors. Purchasers of Securities will also be subject to significant
contractual restrictions on the resale of such Securities until an underwritten
initial public offering for cash of Common Stock, and all shares will carry a
legend to reflect such restrictions. There can be no assurance that such an
offering will occur. See "Management--Stockholders Agreement" and "Description
of Capital Stock."
    

ABSENCE OF PUBLIC MARKET
 
   
     It is not currently anticipated that any of the Securities described in
this Prospectus will be listed on an exchange or other public market or that a
trading market will develop for the Securities. Consequently, the price of the
Securities which may be obtained by a seller in a secondary resale may be
subject to volatility, and given the contractual restrictions or transfer
described in "--Voting Limitations; Restrictions on Resales of Securities" and
"Description of Capital Stock," the resale of such Securities may be difficult
to effect in any case.
    
 
PENNY STOCK RULES
 
   
     As described in "--Absence of Public Market," it is not currently
anticipated that any of the Securities described in this Prospectus will be
listed on an exchange or other public market or that a trading market will
develop for the Securities. As it is not expected that any of the Securities
will be traded on an exchange or quoted on Nasdaq, the Securities will be
subject to Rule 15g-9 under the Exchange Act, which, among other things,
requires that brokers/dealers satisfy special sales practice requirements,
including making individualized written suitability determinations and receiving
any purchaser's written consent prior to any transaction. If the Securities
could also be deemed penny stocks under the Securities Enforcement and Penny
    
 
                                       9
 
<PAGE>
Stock Reform Act of 1990, this would require additional disclosure in connection
with trades in the Securities, including the delivery of a disclosure schedule
explaining the nature and risks of the penny stock market. Such requirements
could severely limit the liquidity of the Securities and the ability of the
purchasers in this offering to sell their Securities in the secondary market.
 
   
OWNERSHIP OF STOCK BY DIRECTORS AND EXECUTIVE OFFICERS
    
 
   
     The executive officers and directors of the Company own 100% of the Class A
Common Stock of the Company (which as of October 4, 1996 represents
approximately 16% of the outstanding capital stock of the Company). The holders
of Class A Common Stock are entitled to elect five of the 18 members of the
Board of Directors.
    
 
   
     The executive officers and directors of the Company own, either directly or
indirectly through their equity interests in Medical Holdings Limited
Partnership ("MHLP") 23.4% of the Class B Common Stock (which as of October 4,
1996 represents approximately 10% of the Company's outstanding capital stock).
Five directors of the Company own 29.4% of the issued and outstanding capital
stock of BMGGP, Inc., the general partner of MHLP. MHLP owns 87.9% of the
Company's issued and outstanding Class B Common Stock (which as of October 4,
1996 represents 43.2% of the outstanding capital stock of the Company). The
holders of Class B Common are entitled to elect eight of the 18 members of the
Board of Directors.
    
 
   
     Two directors of the Company are executive officers of the holder of Series
A Preferred Stock. The holder of Series A Preferred Stock is entitled to elect
two of the Company's directors. Two directors of the Company are executive
officers or directors of the parent company of the holder of Series B Preferred
Stock. The holder of Series B Preferred Stock is entitled to elect two of the
Company's directors. One of the directors of the Company is an executive officer
of the holder of Series C Preferred Stock. The holder of Series C Preferred
Stock is entitled to elect one of the Company's directors.
    
 
   
     Accordingly, the executive officers and directors may have a significant
impact on the business, policies and affairs of the Company. See "Principal
Stockholders".
    
 
KEY EMPLOYEES
 
   
     The Company depends to a significant extent on key management, technical
and marketing personnel, and depends particularly on the efforts of Mr. Gold and
Drs. Rifkin and Kimmel. The Company's growth and future prospects will depend in
large part upon its ability to attract, motivate and retain highly qualified
personnel. The loss of any key personnel or the inability to hire or retain
qualified personnel could have a material adverse effect on the operating
results and financial condition of the Company. See "Management."
    
 
REGULATION
 
   
     While the Company is not currently subject to regulation as an insurer or
health care provider, the insurance and health care business generally and the
Company's business described generally herein are subject to extensive and
pervasive Federal and state regulation pursuant to current statutes and
regulations. Health care regulation has been subject to rapid and pervasive
change in recent years. Congress and various state legislatures are expected to
continue to consider various legislative proposals for health care reform,
including proposals intended to control public and private spending on health
care as well as provide increased public access to the health care system and
maintain broad physician access to health care delivery systems. Changes in the
regulations or reinterpretations of existing regulations may significantly
affect the Company. For example, the staff of the Maryland Insurance Commission
has published its view that certain of the Company's (and similar Managed Care
entities') proposed methods of payment to physicians and other providers may
require the Company and such other Managed Care entities to subject themselves
to regulation as insurance companies. There can be no assurance that the
Company's efforts to conduct itself in such a manner so as not to subject itself
to regulation will be successful, and the imposition of such regulation could
have a material adverse effect on the Company. Regulation which affects the
IPAs, Core Medical Groups, hospitals and other providers of health care could
have a material adverse effect on the operating results and financial condition
of the Company.
    
 
     Some of the Company's business relationships as presently contemplated may
not qualify for "safe harbor protection" under the Medicare Fraud and Abuse
Rules or for an exception under the Federal and Maryland laws discussed in
"Business--Regulation." Such laws are broadly drafted, and their application to
arrangements such as those described herein is often uncertain. Since inquiries
under such laws are highly factual, it is not possible to predict with certainty
how they may be applied to the arrangements in which the Company, the Core
Medical Groups and the Core Medical Group's employee physicians are anticipated
to participate. Although the Company believes that it is and will be in
compliance with these laws
 
                                       10
 
<PAGE>
   
with respect to its own operations, including its contractual relationship with
Core Medical Groups, IPAs and other providers, there can be no assurance that
enforcement authorities will not assert that the Company, or certain
transactions into which the Company has or will have entered, has violated or is
violating such laws, or that if any such assertion were made, that the Company
would prevail, or whether any sanction imposed would have a material adverse
effect on the operations of the Company. Even the assertion of a violation of
such laws could have a material adverse effect on the operating results and
financial condition of the Company.
    
 
   
     The Company enters into contracts with physicians, who are not employees of
Core Medical Groups, and other health care professionals as independent
contractors and, in accordance with federal and state tax guidelines pertaining
to independent contractors, and neither the Company nor any Core Medical Groups
withholds federal or state income taxes, make federal or state unemployment tax
payments or provide workers' compensation insurance with respect to such
independent contractors. However, a determination by taxing authorities to the
contrary with respect to the classification of such physicians or other health
care professionals as independent contractors could have a material adverse
effect on the operating results and financial condition of the Company.
    
 
   
     Finally, the body of law applicable to the delivery of, and payment for,
health care services, aspects of which are summarized in "Business--Regulation,"
is subject to rapid substantive change. All such laws, regulations, and
interpretations are subject to amendment or other substantive change at any
time. There can be no assurance that the business of the Company could have a
material adverse effect on the operating results and financial condition of the
Company.
    
 
POTENTIAL EXPOSURE TO PROFESSIONAL LIABILITY; AVAILABILITY OF INSURANCE
 
     In recent years, physicians, hospitals and other participants in the health
care industry have become subject to an increasing number of lawsuits alleging
medical malpractice and related legal theories. Many of these lawsuits involve
large claims and substantial defense costs. The Company does not engage in the
practice of medicine or provide medical services, nor does it control the
practice of medicine or the provision of health care services by physicians and
other providers within its provider networks or the compliance with regulatory
requirements directly applicable to such providers and the provider network
entities with whom they contract. Nonetheless, the Company maintains
professional malpractice and general liability insurance in amounts deemed
appropriate by management based on the nature and risks of the Company's
business. In addition, each physician, physician network entity and other
provider is required to maintain professional liability insurance coverage, and
the Company generally is indemnified under each of the management agreements by
such entity for liabilities resulting from the performance of services by such
providers. Although the Company currently is not a party to any material
litigation relating to the practice of medicine, there can be no assurance that
the Company will not become involved in such litigation in the future, that any
claim or claims arising from such litigation will not exceed the Company's
insurance coverage or that such coverage will continue to be available, any of
which could have a material adverse effect on the Company.
 
ANTI-TAKEOVER CONSIDERATIONS
 
     Certain provisions of the Company's Articles of Incorporation and Bylaws
and agreements to which the Company is a party could, together or separately,
discourage potential acquisition proposals or delay or prevent a change in
control of the Company, even when stockholders other than the Company's
principal stockholders consider such a transaction to be in their best interest.
Accordingly, such provisions may limit the price that certain investors might be
willing to pay in the future for Securities. See "Description of Capital Stock"
and "Management--Stockholders Agreement."
 
ANTITRUST CONSIDERATIONS
 
   
     The Company and its Network Physicians, and other entities with which it
contracts are subject to the United States, state and District of Columbia
antitrust statutes as well as to the interpretations of such statutes by the
courts. Because the Company will be contracting with Payors and with providers
for the provision of health care services by providers who could be deemed to
compete for the provision of such services, and for other reasons, the Company,
Network Physicians and other entities with which it contracts could be subject
to public and private investigations and enforcement actions under such
statutes. The health care sector is undergoing significant change and is highly
competitive. See "Risk Factors--Competition." The Company has consulted with
counsel concerning the appropriateness of its contracting activities under such
statutes and believes that all of its present and proposed activities are
consistent with such statutes and interpretive guidelines issued by the
Department of Justice, the Federal Trade Commission and other regulatory
agencies. There can, however, be no assurance that the Company will not be
challenged on these grounds.

<PAGE>
                                USE OF PROCEEDS
 
   
     Securities may be issued from time to time in connection with the
acquisition of medical practices or other transactions with physicians. In
exchange for such Securities (and other consideration), the Company expects to
receive certain assets and/or ownership interests of such practices, as well as
certain contractual rights. The Company will issue Securities only in connection
with the acquisition of medical practices or other transactions with physicians
and will not receive cash proceeds in connection with the issuance of the
Securities.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
   
     OVERVIEW. The Company was incorporated in June 1994 and commenced
operations in February 1995. The Company is the substitute corporate entity
formed to reorganize the business of Baltimore Medical Group, P.A. ("BMGPA").
BMGPA was incorporated in January of 1993.
    
 
   
     As of June 30, 1996, there were approximately 637 Network Physicians in
five regional networks throughout the State of Maryland, including approximately
155 PCPs, 92 obstetrician/gynecologists and 390 specialist physicians. Of these,
74 were Equity Physicians, of which 48 had transferred their practice assets to
the Company or one of its subsidiaries and 26 had entered into binding
agreements to complete such transactions. As of October 4, 1996, there were
approximately 694 Network Physicians in six regional networks throughout the
state of Maryland, including approximately 176 PCPs, 95
obstetrician/gynecologists, and 423 specialist physicians. Of these, 90 were
Equity Physicians, of which 57 had transferred their practice assets to the
Company or one of its subsidiaries, 17 had entered into binding agreements to
complete such transactions and 16 were subject to a letter of intent with
respect to an acquisition which the Company believes will be completed by
December 31, 1996.
    
 
   
     The Company provides services to its Network Physicians, who deliver health
care services to patients under various reimbursement mechanisms. The Company's
level of profitability depends on (i) increasing the number of Network
Physicians, (ii) attracting patients to enroll in benefit plans that enter into
Global Capitated Contracts with the Company (principally Medicare
beneficiaries), (iii) securing additional and maintaining Global Capitated
Contracts, with adequate reimbursement rates and (iv) generating earnings
through assisting Network Physicians in managing the delivery of high quality
care at a cost less than the reimbursement received under Global Capitated
Contracts.
    
 
   
     SOURCE OF REVENUES AND EARNINGS. The Company derives substantially all of
its net revenue from (i) direct patient and third party billings and, in the
case of primary care physicians, the capitated gatekeeper payments for medical
services provided by physicians within the Core Medical Groups ("Net Physician
Revenue") and (ii) payments made by Payors to the Company pursuant to Full Risk
Contracts or Global Capitated Contracts ("Global Capitation Revenue").
    

   
     Net Physician Revenue is recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between customary and usual rates for physician services and amounts
reimbursable by government sponsored healthcare programs (I.E., Medicare and
Medicaid), commercial insurance carriers and other health insurance programs.
Global Capitation Revenue is recognized when payments are received. As of June
30, 1996, approximately $1,200,000 of the Company's accounts receivable
represented amounts due from the Medicare and Medicaid programs.
    
 
   
     The Company acquires certain medical practices from Equity Physicians and
enters into long-term contracts with Core Medical Groups who employ the
physicians. The agreements entered into as part of the acquisitions convey to
the Company perpetual, unilateral control over the assets and operations of the
various Core Medical Groups. The Company's PSO Agreements have a 30 year term
with unlimited 10 year renewals. Perpetual control by the Company is evidenced
by (i) the Company's exclusive right to manage each Core Medical Group's
business (other than matters involving clinical judgment and certain health care
services), (ii) its control over the admission and withdrawal of the members of
the Core Medical Group, (iii) its responsibility for all liabilities and
obligations of the Core Medical Group, (iv) its exclusive right to contract for
the Core Medical Groups, (v) the length of the original term of the PSO
Agreements, (vi) the Company's ownership of the assets used by the Core Medical
Group, (vii) the commonality between the stockholders, officers and directors of
the Company and the Core Medical Groups, (viii) the continuing investment of
capital by the Company, (ix) the employment of and the incurrence of expenses
for the majority of the non-physician personnel and (x) the nature of the
services provided to the Core Medical Groups by the Company. The Company's
financial relationship with each practice offers the physicians access to
capital, management expertise, sophisticated information systems and Managed
Care contracts. Notwithstanding the lack of any ownership of the equity
interests in such entities, consolidation of the Core Medical Groups is
necessary to present fairly the financial position and results of operations of
the Company because there exists a parent-subsidiary relationship by means other
than record ownership of any equity interests.
    
 
   
     The historical results of operations presented herein are not necessarily
indicative of anticipated future results. Physicians, prior to becoming
employees of the Core Medical Groups, derived substantially all of their
revenues through activities related to Net Physician Revenue. The Company
derives minimal earnings from Net Physician Revenue as the proceeds from these
sources are paid to the Core Medical Groups for the accounts of the physicians
in Core Medical Groups ("Physician
    
 
                                       14

Services and Other Provider Costs") and are used by the Company to meet the
costs of services provided to the Core Medical Groups ("Care Center Costs"). A
central tenet of the Company's strategy is changing the revenue mix of its
Network Physicians from fee-for-service reimbursement to pre-paid arrangements,
principally those involving Global Capitated Contracts for Medicare
beneficiaries.
    
 
   
     The Company's primary source of future earnings is expected to be Global
Capitation Revenue. Under such arrangements, the Company receives a fixed fee
from a Payor in exchange for undertaking the obligation to provide or arrange
for the provision of substantially all of the health care services required by
the Enrollees (the majority of expenses associated with such activities are
reported as "Medical Services Expense"). These services include not only
services provided by the Company's Network Physicians but also hospitalization,
specialty care and ancillary services which are subcontracted by the Company.
    
 
   
     The inability of the Company to renew its current Payor contracts, to
maintain favorable terms of such contracts, to attract patients who enroll in
such benefit plans, to expand such contracts to other geographical areas in the
Baltimore and Washington metropolitan area and surrounding regions or to manage
successfully the cost of care would materially and adversely affect the
Company's revenues and primary source of earnings.
    
 
   
     As of October 4, 1996, the Company is working cooperatively with two Payors
to attract both Medicare and commercial patients who enroll in benefit plans
that enter into Global Capitated Contracts with the Company. As of June 30, 1996
and as of October 4, 1996, there were not a sufficient number of patients
enrolled in benefit plans under the Company's Global Capitated Contracts to
cover its operating costs. To the extent patients do not enroll in such benefit
plans in adequate numbers, it will have a material adverse effect on the
operating results and financial condition of the Company.
    
 
   
     The Company's ability to manage successfully the cost of care under such
contracts depends on the overall health of its patients, its ability to manage
appropriate and timely utilization of medical resources and its ability to
maintain favorable agreements with other health care providers (E.G., hospital
and ancillary services). To the extent the Company is unable to provide or
arrange for the provision of substantially all of the health care services
required by its patients at a cost less than the fixed fee received from a
Payor, it will have a material adverse effect on the operating results and
financial condition of the Company.
    
 
   
     In the future, the Company expects to derive meaningful revenues and
earnings from other sources including (i) the management of Specialty Care Core
Medical Groups, (ii) the management fees growth of multi-specialty Core Medical
Group revenue, (iii) other management fees and (iv) the growth of Core Medical
Groups revenue from increased physician productivity.
    
 
   
     ACQUISITIONS/OTHER PHYSICIAN TRANSACTIONS. The Company has acquired the
furniture, fixtures and equipment (at net book value, which the Company and each
Equity Physician agree approximates fair value), intangible assets, and the
accounts receivable of certain medical practices in exchange for consideration
of cash, stock and/or notes payable. In addition to such consideration,
substantially all direct costs associated with the acquisition are capitalized.
(See "History of the Company" for a description of the number of practices
acquired and the amount and form of consideration paid to consummate each
transaction.)
    
 
   
     At the time of acquisition, Equity Physicians typically enter into 10-year
employment agreements with a Core Medical Group. Further, each Core Medical
Group enters into a PSO Agreement with the Company generally for 30 years, with
automatic terms of renewal, pursuant to which the Company provides management
and administrative services to the Core Medical Group and the Core Medical Group
agrees to provide medical services to the Company's patients.
    
 
   
     Certain acquisitions are subject to reacquisition rights whereby the
physicians may rescind the transaction typically within a nine month period from
the date of closing. Pursuant to such reacquisition rights, such physicians may
repurchase substantially all of the assets previously acquired at the price paid
by the Company at the closing. To date, one physician had exercised his
reacquisition rights. In that instance, the practice had not actually been
consolidated into the operations of the Company and as a consequence had no
material financial effect on the Company. As of June 30, 1996, of the 44
physicians who had been granted reacquisition rights, 25 had such rights still
available. These physicians represented approximately $2,574,826 or 25% of the
Company's net revenue of $10,284,590. As of October 4, 1996, of the 53
physicians who had been granted reacquisition rights, 26 had such rights still
available. Although the Company does not believe that substantial rescissions
will occur, the exercise of such rights by a substantial number of physicians
would have a material and adverse effect on the operating results and financial
condition of the Company.
    
 
                                       15
 
<PAGE>
   
     Of the 74 Equity Physicians as of June 30, 1996, 26 had entered into
binding letters of intent to sell medical practices to the Company and become
employees of Core Medical Groups. As of the date of this Prospectus, 9 of these
physicians had consummated the aforementioned transactions. The Company expects
the remainder of these transactions to close by December 31, 1996.
    
 
   
     The Company intends to continue acquiring certain medical practices and
obtaining managed care contracting rights and is currently in active discussions
with a number of primary and specialty care physicians. The Company intends to
begin management of Specialty Care Core Medical Groups pursuant to a medical
practice asset acquisition of and merger with a 16-physician cardiology practice
and the formation of a Cardiology Core Medical Group. The consideration in such
transaction will consist of shares of Class B Common Stock and a note payable
for the accounts receivable.
    
 
   
     The Company also expects to derive revenues and earnings from the
participation of physicians in its IPAs. As of June 30, 1996, 29 Network PCPs
were participants in the Company's IPAs. As of October 4, 1996, 50 Network PCPs
were participants in the Company's IPAs. (See "Business--Development of
Integrated Health Care Delivery System--Independent Physician Associations").
    
 
RESULTS OF OPERATIONS
 
   
     The Company's operating results are significantly affected by the number of
Network PCPs, the number of Network PCPs participating in Global Capitated
Contracts, the number of executed Global Capitated Contracts, and the number of
patients enrolled in benefit plans under Global Capitated Contracts with the
Company. The following table summarizes the Company's history with respect to
Network PCPs, executed Global Capitated Contracts and patients enrolled in
benefit plans under Global Capitated Contracts with the Company:

(1) Represents physicians included in BMGPA as of June 30, 1994.
 
   
(2) There is a lag between when physicians join networks and when they become
    eligible to participate in Global Capitated Contracts as a result of the
    credentialing process and other internal Company controls.
    

   
     The increase in the number of Network Physicians has contributed to the
increase in revenue growth as well the increase in operating costs to support
physician growth. In preparation for the acquisition of medical practices and
other physician transactions, the Company had invested in the personnel and
infrastructure necessary to accommodate its anticipated growth, which resulted
in substantial increases in corporate expenses throughout 1996 and 1995.
    
 
   
     The Company's three Global Capitated Contracts noted above were effective
January 1, April 1 and June 1, 1996, respectively. Since the Company executed
its Global Capitated Contracts in the latter half of the year ended June 30,
1996 and its Network PCPs experienced the lag time in becoming eligible to
participate in such contracts, the Company's global capitated revenue was less
than expected.
    
 
   
     Due to the limited operating period of the Global Capitated Contracts, the
number of physicians eligible to participate in Global Capitated Contracts, the
resulting relatively small number of patients enrolled in benefit plans under
Global Capitated Contracts with the Company and the Company's limited experience
with the Payors, the Company has recognized a loss of approximately $280,000
related to such contracts for the year ended June 30, 1996.
    
 
   
     Although the Company expects that it will derive earnings from such
contracts in the future given larger numbers of Network PCPs participating in
Global Capitated Contracts, the expected larger number of enrolled patients and
greater experience with the Payors, there can be no assurance that this will be
the case. (See "Risk Factors--Dependence on Managed Care"). Because of the
Company's limited operating history, the limited period in which it has been
assisting and managing Network Physicians, its limited experience with full and
shared-risk capitated arrangements and the effects of the acquisitions, the
Company does not believe that the period to period comparisons, percentage
relationships within periods and apparent trends set forth below are necessarily
indicative of future operations.

     YEAR ENDED JUNE 30, 1996 COMPARED TO YEAR ENDED JUNE 30, 1995.
    

   
     NET REVENUES. The Company's net revenues increased to $10,284,590 for the
year ended June 30, 1996 from $3,315,332 for the year ended June 30, 1995. This
trend was attributable to (i) the increase in net physician revenue to
$9,902,528 or 96.3% of net revenue from $3,315,332 or 100% of net revenue and
(ii) the increase in global capitation revenue to $382,062 or 3.7% of net
revenue from $0 over the prior year. These increases resulted primarily from the
increase during the year ended June 30, 1996, in the number of Network
Physicians who had consummated underlying transactions, from 24 to 88, as well
as the increase in the number of Network PCPs participating in Global Capitated
Contracts from 0 to 45 and the increase in the number of Global Capitated
Contracts from 0 to 3 over the same time period.
    
 
   
     PHYSICIAN SERVICES AND OTHER PROVIDER COSTS. Physician services and other
provider costs were $4,525,340 or 44.0% of net revenue for the year ended June
30, 1996 compared to $1,760,245 or 53.1% of net revenue for the year ended June
30, 1995. The increases resulted from increases in the number of Network
Physicians who had consummated underlying transactions from 24 to 88 during the
year ended June 30, 1996. While these expenses are expected to increase as the
Company continues adding Network Physicians, the Company also expects that these
expenses will decline as a percentage of net revenues as the Company's medical
services expense grows as a result of the growth of the Company's Global
Capitated Contracts.
    
 
   
     MEDICAL SERVICES EXPENSE. Medical services expense was $662,671 or 6.4% of
net revenue for the year ended June 30, 1996 compared to $0 or 0% of net revenue
for the year ended June 30, 1995. These increases resulted from the increase in
the number of Network PCPs participating in Global Capitated Contracts from 0 to
45 and the increase in the number of Global Capitated Contracts from 0 to 3 over
the same time period. The Company expects these expenses to increase as the
number of Network PCPs participating in and the number of patients enrolled in
benefit plans under Global Capitated Contracts with the Company grows.
    
 
   
     CARE CENTER COSTS. Care center costs were $6,011,470 or 58.4% of net
revenue for the year ended June 30, 1996 compared to $2,157,549 or 65.1% of net
revenue for the year ended June 30, 1995. These increases resulted from the
increases in the number of Network Physicians who had consummated underlying
transactions from 24 to 88. While these expenses are expected to increase as the
Company continues adding Network Physicians, the Company expects that these
expenses will decline as a percentage of net revenue.
    
 
   
     GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
were $5,342,429 or 51.9% of net revenue for the year ended June 30, 1996
compared to $1,587,481 or 47.9% of net revenue for the year ended June 30, 1995.
These increases resulted primarily from (i) increased compensation expenses from
expansion of the Company's corporate management team, as well as its marketing,
acquisitions, network development and care management departments and (ii)
additional costs incurred in adding physicians to the Company's networks and
attracting patients who enroll in benefit plans under Global Capitated
Contracts. While these expenses are expected to increase as the Company adds
Network Physicians, the Company expects that these expenses will decline as a
percentage of net revenues.

     DEPRECIATION AND AMORTIZATION EXPENSES. Depreciation and amortization
expenses were $438,143 or 4.3% of net revenue for the year ended June 30, 1996
compared to $35,367 or 1.0% of net revenue for the year ended June 30, 1995.
These increases resulted primarily from intangibles acquired from, medical
practice assets acquired from and employment agreements executed with Equity
Physicians, as well as certain fixed asset additions. While these expenses are
expected to increase as the Company continues adding Equity Physicians, the
Company expects that these expenses will decline as a percentage of net revenue.
    
 
   
     INTEREST AND OTHER INCOME. Interest and other income was $291,553 or 2.8%
of net revenue for the year ended June 30, 1996 compared to $199,166 or 6.0% of
net revenue for the year ended June 30, 1995.
    
 
   
     INTEREST EXPENSE. Interest expense was $242,513 or 2.4% of net revenue for
the year ended June 30, 1996 compared to $30,690 or 0.9% of net revenue for the
year ended June 30, 1995. These increases resulted primarily from the increase
in the level of borrowings.
    
 
   
     INCOME TAX EXPENSE. In light of the Company's loss and its allowance for
deferred tax assets, for the years ended June 30, 1996 and June 30, 1995, the
Company did not require a provision for income taxes.
    
 
   
     NET INCOME (LOSS). The Company had a net loss of $6,646,423 for the year
ended June 30, 1996 compared to $2,056,834 for the year ended June 30, 1995.
    

   
     YEAR ENDED JUNE 30, 1995 COMPARED TO YEAR ENDED JUNE 30, 1994.
    
 
   
     NET REVENUES. The Company's net revenues increased to $3,315,332 for the
year ended June 30, 1995 from $2,166,419 for the year ended June 30, 1994. This
increase resulted primarily from the increase in the number of Network PCPs from
13 to 24 over the same time period. The Company did not have any Global
Capitated Contracts during this time period.
    
 
   
     PHYSICIAN SERVICES AND OTHER PROVIDER COSTS. Physician services and other
provider costs were $1,760,245 or 53.1% of net revenue for the year ended June
30, 1995 compared to $681,901 or 31.5% of net revenue for the year ended June
30, 1994. These increases resulted from the increases in the number of Network
PCPs from 13 to 24.
    

   
     CARE CENTER COSTS. Care center costs were $2,157,549 or 65.1% of net
revenue for the year ended June 30, 1995 compared to $1,075,365 or 49.6% of net
revenue for the year ended June 30, 1994. These increases resulted from the
increases in the number of Network PCPs from 13 to 24.
    
 
   
     GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
were $1,587,481 or 47.9% of net revenue for the year ended June 30, 1995
compared to $288,621 or 13.3% of net revenue for the year ended June 30, 1994.
These increases resulted primarily from (i) increased compensation expenses from
development of the Company's corporate management team, as well as the formation
of its marketing, acquisitions, network development and care management
functions and (ii) additional organizational costs from developing physician
networks.
    
 
   
     DEPRECIATION AND AMORTIZATION EXPENSES. Depreciation and amortization
expenses were $35,367 or 1.0% of net revenue for the year ended June 30, 1995
compared to $17,871 or 0.8% of net revenue for the year ended June 30, 1994.
These increases resulted primarily from acquiring intangibles from, acquiring
medical practice assets from and executing employment agreements with Equity
Physicians, as well as purchasing certain fixed assets.
    
 
   
     INTEREST AND OTHER INCOME. Interest and other income was $199,166 or 6.0%
of net revenue for the year ended June 30, 1995 compared to $85,442 or 3.9% of
net revenue for the year ended June 30, 1994.
    
 
   
     INTEREST EXPENSE. Interest expense was $30,690 or 0.9% of net revenue for
the year ended June 30, 1995 compared to $16,153 or 0.8% of net revenue for the
year ended June 30, 1994. These increases resulted primarily from the increase
in the level of borrowings.
    

   
     INCOME TAX EXPENSE. Because it incurred losses during 1995 and was an
S-corporation in 1994, the Company did not have a provision for income taxes.
    
 
   
     NET INCOME (LOSS). The Company had a net loss of $2,056,834 for the year
ended June 30, 1995 compared to net income of $171,950 for the year ended June
30, 1994.
    
 
LIQUIDITY, CASH FLOW AND CAPITAL RESOURCES
 
   
     OVERVIEW. The Company requires capital primarily to acquire certain medical
practices from Equity Physicians, to develop and install information systems for
care management functions (necessary for the management of provider risk-
    
 
                                       18

sharing contracts), for billing and collection services and to meet working
capital requirements to cover operating expenses. Through June 30, 1996, the
Company had met its cash requirements primarily through private placements of
preferred stock and through bank borrowings. As of June 30, 1996, the Company
had cash and cash equivalents of approximately $1,400,837, and as of September
30, 1996 had cash and cash equivalents of approximately $6,300,000. The Company
intends to meet its cash requirements after June 30, 1996 through a combination
of some or all of the following sources of capital: (i) up to $20,000,000 from
the proceeds of the sale of Series C Preferred Stock, (See "--Subsequent
Events"), (ii) up to $10,000,000 from the establishment of the First National
Bank Facility (See "--Subsequent Events"), (iii) up to $40,000,000 from the
private placement of subordinated notes (which may contain warrants) and (iv) up
to $20,000,000 from the private placement of Series D Preferred Stock (See
"--Subsequent Events").
    
 
   
     Capitation arrangements generally have a favorable impact on cash flow
because the Company receives capitation revenue prior to incurring costs
associated with services provided under those contracts. Certain risk pool
arrangements negatively impact cash flow because certain medical service
expenses in connection with these arrangements are not finalized and settled by
the Company until significantly after it has received payment for the services.
    
 
   
     LIQUIDITY. At June 30, 1996, the Company had working capital and available
credit facilities of approximately $1,431,204. At September 30, 1996, the
Company had working capital and available credit facilities of approximately
$5,500,000.
    
 
   
     CASH FLOW. Net cash used in operating activities was $5,095,979 for the
year ended June 30, 1996 compared to $1,373,833 for the year ended June 30,
1995. The use of cash for operating activities resulted primarily from (i)
$6,646,423 in net losses, (ii) a $1,271,016 increase in accounts receivable
offset by (iii) a $2,689,914 increase in accrued and other liabilities.
    
 
   
     Net cash used in investing activities was $2,006,362 for the year ended
June 30, 1996 compared to $380,362 for the year ended June 30, 1995. The Company
used $2,133,391 and $241,067 of cash for the acquisition of certain medical
practices and other fixed assets during the years ended June 30, 1996 and 1995,
respectively.
    
 
   
     Net cash provided by financing activities was $8,371,817 for the year ended
June 30, 1996 compared to $1,780,942 for the year ended June 30, 1995. (See
"--Capital Resources".)
    
 
   
     CAPITAL EXPENDITURES. The Company has entered into binding letters of
intent for the acquisition of certain medical practices which, if completed,
would require approximately $2,500,000 in cash and has not committed to any
material additional capital expenditures. Management intends to finance these
expenditures from available capital sources. If additional capital sources are
secured, the Company intends to acquire additional medical practices as well as
incur certain additional fixed assets (See "--Subsequent Events").
    
 
   
     CAPITAL RESOURCES. On February 24, 1995, the Company issued 1,000,000
shares of Series A Preferred Stock to St. Joseph's Medical Center, Inc. (the
"Series A Preferred Stockholder") in exchange for $2,000,000 in cash and
$3,000,000 in a note (the "Series A Note"). The proceeds from this initial
issuance were used to fund the formation of the Company and for the acquisition
of certain medical assets from medical practices of certain Equity Physicians,
the incurrence of corporate expenses and the development of infrastructure in
conjunction with the Company's business strategy.
    
 
   
     On September 27, 1995, the Company received $500,000 in cash payments on
the Series A Note from the Series A Preferred Stockholder. These proceeds were
used to fund corporate expenses and the continuing development of the Company's
infrastructure.
    
 
   
     On December 1, 1995, the Company issued 355,556 shares of Series B
Preferred Stock to Med-Lantic Management Services, Inc. ("the Series B Preferred
Stockholder") in exchange for $4,000,000 in cash and entered into an agreement
("the NationsBank Credit Facility Agreement") with NationsBank of Maryland, N.A.
("NationsBank") as agent, which provides a revolving bank credit facility ("the
NationsBank Credit Facility") with a maximum availability of $4,000,000.
Advances under the NationsBank Credit Facility bear interest at the Company's
option at either NationsBank prime rate or the Eurodollar rate plus 0.75%. The
NationsBank Credit Facility expires on December 31, 1997, and is renewable, at
the sole discretion of NationsBank, for two additional periods of one year each.
    
 
   
     Loans made pursuant to the NationsBank Credit Facility are guaranteed by
the Company's Series B Preferred Stockholder. In exchange for the guarantee of
the NationsBank Credit Facility, the Company issued 88,889 warrants to the
Series B Preferred Stockholder. The guarantee is collateralized by a security
interest in certain contract rights, including rights to the Company's patient
and global capitation receivables, under the PSO Agreements between the Company
and Core Medical
    
 
                                       19

Groups. Upon redemption of the Series B Preferred Stock in the event of the
issuance of junior preferred stock to a holder whose interest are deemed adverse
to the guarantor, the Company is required to obtain a release of the guarantee.
    
 
   
     The proceeds from the issuance of the Series B Preferred Stock were used
for the acquisition of certain medical practices from Equity Physicians, the
incurrence of corporate expenses and the development of the Company's
infrastructure in conjunction with the Company's business strategy. The proceeds
from the NationsBank Credit Facility were used for the acquisition of certain
medical practices from Equity Physicians, the funding of operating expenses and
the funding of capital expenditures. At June 30, 1996 and September 30, 1996
approximately $3,400,000 and $3,600,000, respectively were outstanding under the
NationsBank Credit Facility.
    
 
   
     On June 25, 1996, the Company received $1,000,000 in additional cash
payments on the Series A Note from the Series A Preferred Stockholder. These
proceeds were used to fund the incurrence of corporate expenses and the
continuing development of infrastructure in conjunction with the business
strategy.
    
 
   
     The Company may receive up to $1,500,000 in additional cash payments on the
Series A Note from the Series A Preferred Stockholder, subject to borrowings
under the Bridge Loan Facility described below.
    
 
   
     (For a discussion of the terms of conversion of the Preferred Stock into
Class C Common Stock, see "Description of Capital Stock".)
    
 
   
     SUBSEQUENT EVENTS. On August 15, 1996, the Company established a $1,500,000
bridge loan facility (the "Bridge Loan Facility") with First National Bank of
Maryland, N.A. ("First National"). The Bridge Loan Facility is collateralized by
certain assets of the Company and its affiliates and is guaranteed by the Series
A Preferred Stockholder. Advances under this facility bear interest at a rate of
6.71% per annum. Unless extended, the Bridge Loan Facility matures on October
14, 1996. The Company intends to replace the Bridge Loan Facility with a
$10,000,000 credit facility with First National (the "First National Credit
Facility"). As of October 4, 1996, approximately $983,000 had been advanced
under the Bridge Loan Facility to fund corporate expenses. Although there can be
no assurances the Company will obtain the First National Credit Facility, the
Company is proceeding with the loan approval process with the First National
Bank. The Company believes, based on discussions with First National and the
Series A Preferred Stockholder, that if the loan approval process is not
completed before the maturity date of the Bridge Loan Facility, that the
maturity date will be extended until such time that the loan approval process is
completed. In the event the Company is unable or unwilling to secure the First
National Bank Credit Facility or the maturity date of the Bridge Loan Facility
is not extended, the Bridge Loan Facility will be repaid from the Company's
available cash.
    
 
   
     On September 4, 1996, the Company issued 428,571 shares of Series C
Preferred Stock to Genesis Health Ventures, Inc. (the "Series C Preferred
Stockholder"), in exchange for $7,500,000 in cash. The Company will issue
142,857 additional shares of the Series C Preferred Stock in exchange for
$2,500,000 in cash prior to December 31, 1996 which represents an obligation of
Genesis that must be fulfilled unless the Company is in breach of any of its
loan agreements. The proceeds from these issuances (the "Initial Genesis
Funding") will be used to fund corporate expenses in conjunction with the
business strategy and the acquisition of medical practices or IPA contracting
rights. The Company may issue up to 500,000 additional shares of the Series C
Preferred Stock in exchange for up to $10,000,000 in cash (the "Additional
Genesis Funding") if certain Medicare capitated milestones are achieved.
    
 
   
     The Company intends to obtain up to $40,000,000 from the proceeds of
private placement of Subordinated Notes (the "Subordinated Notes"). Although the
terms of the Subordinated Notes have not been negotiated, the Subordinated Notes
are expected to include warrants to purchase shares of Class C Common Stock and
mandatory and optional redemption features. The Company also intends to obtain
up to $20,000,000 from the proceeds of a private placement of Series D Preferred
Stock, the terms of which have not yet been negotiated. The Company's ability to
consummate the First National Credit Facility or the Subordinated Notes is
subject to the consent of the holders of the Series A, Series B and Series C
Preferred Stock under certain circumstances. (See "Risk Factors--Liquidity:
Restrictions on Financing".)
    

   
     Until the Company and its Payors attract an adequate number of Capitated
Lives in Global Capitated Contracts, the Company expects to incur operating
losses and experience negative operating cash flows. The Company believes that
its cash on hand, the $2,500,000 to be received on or before December 27, 1996
from the holder of Series C Preferred Stock, and the balance remaining available
under the NationsBank Credit Facility, will be sufficient to meet the Company's
immediate working capital needs. However, in the event that the Company either
has not attracted an adequate number of Capitated Lives in Global Capitated
Contracts in order to offset operating expenses, or has not secured some
substantial portion of the additional capital described above, the Company's
operating results and financial condition could be materially and adversely
affected.
    
 
                                       20
 
<PAGE>
   
     In the event that the Company is successful in obtaining the additional
capital described above, in addition to the commitments for capital expenditures
described above (see "--Capital Expenditures"), the Company intends to expend
capital on improving information systems, expanding corporate infrastructure,
and to acquiring medical practices. There can be no assurance that the Company
will be able to establish a First National Credit Facility, consummate an
offering of Subordinated Notes, close the additional issuance of Series C
Preferred Stock pursuant to the Additional Genesis Funding, or consummate an
offering of Series D Preferred Stock on terms favorable or acceptable to the
Company. The inability of the Company to obtain such funding, either in whole or
part, would impair the Company's ability to make intended capital expenditures
and to execute its planned strategy and therefore could have a material adverse
effect on the Company's results of operations and financial condition.
    
 
   
FACTORS THAT MAY AFFECT FUTURE RESULTS
    
 
   
     The future operating results and financial condition of the Company could
be materially and adversely affected by a number of factors such as: risks
relating to the Company's growth strategy including competition for expansion
opportunities, integration risks, dependence on HMO Enrollee growth and the
ability to raise the capital required to support growth; the capitated nature of
revenues and control of healthcare costs; exposure to professional liability;
healthcare reform and government regulation; and the Company's ability to sell
its services profitably, successfully increase market share and manage expense
growth relative to revenue growth. See "Risk Factors."
    
 
                                    BUSINESS
 
INDUSTRY
 
   
     HCFA estimates that 1995 national health spending was approximately one
trillion dollars, with physicians controlling more than 80% of overall
expenditures. Physicians have traditionally provided medical care on a
fee-for-service basis, which provides few incentives for the efficient
utilization of resources and has contributed to increases in health care costs
that are significantly higher than historical inflation rates. Concerns over the
accelerating cost of health care have resulted in the increasing prominence of
managed care, and employers, individuals and the government have increasingly
turned to HMOs and other forms of managed care in an attempt to manage health
care costs more effectively. The number of individuals enrolled in HMOs grew
from 12.5 million Enrollees in 1983 to 54.0 million in 1994, a 14.6% compound
annual growth rate. According to industry sources, there are over 600 HMOs
currently operating in the United States, covering approximately 20% of the U.S.
population. Moreover, Federal and State governments are increasingly using HMOs
to cover health benefits under Medicare and Medicaid programs. The Company
believes that overall enrollment in HMOs will continue to increase due to the
fact that HMOs generally offer lower overall premium costs than traditional
fee-for-service indemnity health insurance.
    
 
   
     Health care in the United States historically has been delivered through a
fragmented system of health care providers, including individual or small groups
of PCPs and specialists. According to the American Medical Association,
approximately 565,000 physicians are actively involved in patient care in the
United States, with approximately 70% of these physicians, or 397,000,
practicing individually or in a two person group. Industry sources estimate that
the physician practice management market is $200 billion.
    
 
   
     In an effort to manage their costs and minimize their risk, HMOs are
shifting from fee-for-service payments for physicians and are increasingly
utilizing "capitation" arrangements. Under capitation arrangements, physicians
receive a fixed monthly fee per assigned enrollee, and in return provide all
services required by such Enrollee in specified areas. Under these arrangements,
physicians assume the risk that they will be able to provide medical care at
costs less than the capitation payment. The Company believes that traditional
PCP and small group specialty practices are at a disadvantage in a managed care
environment because they typically have high operating costs, little bargaining
power with HMOs and other Payors and little or no information or data regarding
utilization or the total health care costs of treating their patients, and
therefore are unable to assess the business risks of managed care. In addition,
these physician practices almost always have insufficient capital to purchase
new technologies and lack the sophisticated systems necessary to track patient
data and performance and to contract effectively with HMOs and other managed
care entities. As a result, PCPs and specialist physicians are increasingly
abandoning traditional practices in favor of affiliating with larger
organizations, such as the Company.
    
 
     Traditionally, the primary care or "general practice" physician has enjoyed
broad patient loyalty and continuity and has been the point of entry into the
health care system for many patients, including those who require the services
of a specialist physician. The traditional role of the PCP has been to refer the
patient to a specialist physician who is typically not affiliated with the PCP
in the practice of medicine. Fee-for-service reimbursement to, and therefore
compensation levels for, specialist
 
                                       21
 
<PAGE>
physicians have significantly exceeded the compensation levels for PCPs. The
result is that, under a traditional fee-for-service environment, the PCP largely
controls the amount of care their patients receive without any information about
the cost or efficacy of the care or sharing in any of the revenues generated by
that care.
 
     The Company believes that its strategy of establishing and consolidating
Core Medical Groups, IPAs and related networks based upon PCPs, and entering
into arrangements with specialist networks, to compete in the managed care
marketplace will result in significant revenues from capitated contracts with
HMOs and other Payors to pay for flexible managed care of patients.
 
STRATEGY
 
   
     The Company's strategy is based upon the concept that recent changes in the
health care industry have created an opportunity to establish physician provider
groups and IPAs that can provide a broad range of medical services to patients
and prepaid Managed Care members, more efficiently and profitably than is
possible under the traditional "fee-for-service" or "HMO network" models. The
Company believes that the development of an integrated health care delivery
system will allow it to negotiate Global Capitated Contracts with HMOs and other
Payors that will enable the Company to reduce administrative costs and derive
revenues by encouraging preventive medicine and by the appropriate utilization
of medical resources. The key elements of this strategy are as follows:
    
 
   
     INTEGRATING HEALTH CARE PROVIDERS INTO COMPREHENSIVE NETWORKS. The Company
consolidates individual or groups of PCPs, specialists, hospitals and other
providers in the Baltimore and Washington metropolitan areas and surrounding
regions into primary care-driven comprehensive health care networks, permitting
the Company to assume full risk under contracts with Managed Care Plans for
certain health care services. Physicians will enter employment, IPA, joint
venture or other contractual relationships with the Company, while the Company
will negotiate favorable rates, to the extent feasible, from hospitals and other
providers of medical services. All participants must agree to follow the
Company's PCP-driven clinical protocols and procedures, and are closely
supervised by the PCPs. The Company believes that its health care delivery
networks (i) provide physicians with greater access to managed care contracts by
facilitating contractual relationships with multiple HMOs or other Payors, (ii)
establish a single point of entry into an integrated health care delivery
network for HMOs and other Payors, and (iii) offer patients a comprehensive
range of high quality medical care. The Company's development of its healthcare
network is currently focused on the Baltimore and Washington metropolitan area
and surrounding areas. After the establishment of its network in this market,
the Company may expand outside of this region.
    
 
   
     ATTRACTIVE TO PHYSICIANS. The Company seeks to be attractive to physicians,
and particularly to PCPs. The Company is dedicated to the creation of
professionally managed networks that grant physicians clinical autonomy and the
ability to practice medicine using clinical protocols and procedures developed
in cooperation with fellow physicians. The Company's strategy is to have a
network structure that allows physicians greater access to managed care
contracts and hospital case management than they could obtain independently, and
relieves physicians of burdensome administrative responsibilities.
    
 
   
     FOCUS ON MANAGED CARE. The Company designs its physician-driven health care
delivery networks to meet the needs of HMOs, other Payors and patients, to
identify and recruit primary and specialty care physicians, hospitals and other
providers and to integrate such providers into networks that provide coordinated
medical coverage to such Payors' Enrollees. The Company seeks to benefit from
the desire of Payors and employers to reduce health care costs and risks, and
the trend toward prepaid managed health care. Rather than entering into an
exclusive arrangement with any single Payor, the Company seeks contracts with a
risk sharing arrangement, including Global Capitated Contracts, with each of the
HMO Payors in a region in which Network Physicians and other physicians operate
their medical practices. Because the Company's networks are PCP-driven and
patient-PCP relationships are typically strong, the Company expects that the
relatively large, pre-existing patient base of such PCP practices will be
attractive to Payors. The Company believes that its emphasis on wellness network
structure and management techniques (including the collection of meaningful
data, information systems, care utilization and quality management systems,
referral procedures, risk management programs, assistance with physician
credentialing and contracting with Payors) will enable it to effectively contain
costs and negotiate favorable capitation and shared risk arrangements.
    
 
   
     MEDICARE MANAGED CARE. An important component of the Company's strategy is
the enrollment of Medicare-eligible persons in the Medicare managed care plans
with which the Company contracts. Reimbursement rates for Medicare patients are
considerably higher than for non-Medicare patients, reflecting the greater
historical expense of providing care to Medicare patients. HCFA estimates that
as of 1993 there were approximately 546,000 Medicare recipients in Maryland,
including 306,000 in the greater Baltimore area, and that only approximately
39,000 are currently enrolled in HMOs in the state of Maryland. The Company's
results of operations are highly dependent on its ability to convert its present
portion of Network
    
 
                                       22
 
<PAGE>
Physicians' current Medicare fee-for-service patients to Medicare managed care
plans and attract new Medicare patients that enroll in Medicare HMOs with whom
the Company contracts.
 
   
     The Company currently has a Medicare Global Capitated Contract with Health
Care Corporation of the Mid-Atlantic and a Medicare Global Capitated Contract
with Chesapeake Health Plan under which the Company receives capitation payments
on a per member per month basis for each subscriber who participates in one of
the plans and is enrolled with a Network Physician. For the Medicare patients
enrolled in the plans contracting with a Network Physician, the Company receives
capitation payment revenue, assumes the risk of the cost of providing care to
the patients, and seeks to earn revenues by encouraging preventative medicine,
high quality care and appropriate utilization of medical resources.
    
 
   
     EFFECTIVELY MANAGE THE DELIVERY OF MEDICAL CARE. The Company seeks to
deliver quality medical care while controlling costs and ensuring patient
satisfaction. Accordingly, the Company seeks qualified physicians and
coordinates the provision of health care services among the physicians,
hospitals, and other providers within its networks. The Company seeks (i) to
change the focus of health care utilization to foster health promotion at the
PCP and care manager level, (ii) to reduce specialist and other provider costs
through early and aggressive intervention by affiliation with fewer specialists
who will benefit from increased Managed Care activities at lower reimbursement
rates, and (iii) to reduce hospital, particularly inpatient, costs through more
efficient utilization of lower cost components of the health care delivery
system when appropriate without sacrificing quality. In addition, the Company
will monitor the delivery of high-quality medical care through the development
and implementation of information systems tailored to managed care. The Company
believes that much of the high cost of health care is caused by the lack of
incentives in the health care system to help patients avoid high-cost, episodic
care, and excessive utilization of high cost services. The Company believes that
lower cost care, such as outpatient or home care, where appropriate, is both
preferable to the patient and less expensive to the Payor.
    
 
     EXPANSION STRATEGY. The Company must actively develop or consolidate
existing and new markets through selective acquisitions and joint ventures. The
Company develops existing markets by (i) capturing additional revenues from
existing practices as patients migrate from traditional fee-for-service plans to
capitated managed care programs, (ii) adding new physicians to existing
networks, and (iii) contracting with Payors to expand the number of capitated
lives within existing physician practices.
 
HISTORY OF THE COMPANY
 
   
     INITIAL TRANSACTIONS. The Company was incorporated in June 1994 and
commenced operations on February 24, 1995. The Company is the substitute
corporate entity formed to reorganize the business of Baltimore Medical Group,
P.A. ("BMGPA"). BMGPA was incorporated in January 1993 and commenced operations
in May 1993.
    
 
   
     At the time of the initial formation of BMGPA, the physician owners created
BMGPA as a primary care-driven provider group that would ultimately create
enough critical mass effectively to compete in the rapidly changing health care
market. The physicians of BMGPA also planned the formation of one or more
business entities to provide the management, administrative, contracting,
recruiting and marketing services needed by the physicians. The Company was
organized to provide, or cause to be provided, all of the business services that
were required by BMGPA other than the provision of medical care to patients. In
February 1995, the Company commenced operations by (i) reorganizing BMGPA and
facilitating the transfer of its laboratory assets to Baltimore Medical Group,
LLC, the Company's first Core Medical Group, (ii) assuming exclusive management
responsibility and control over the practice assets and employees of the 15
BMGPA physicians, and (iii) issuing Class B Common Stock of the Company to a
partnership owned primarily by the 15 BMGPA physicians. Scott Rifkin, M.D., Alan
Kimmel, M.D., J. David Nagel, M.D., Peter LoPresti, D.O. and Robert Ancona,
M.D., five of the original members of Baltimore Medical Group, LLC, are
currently directors of the Company.
    
 
   
     The Company received the BMGPA physicians' assets in a reorganization
through Medical Holdings Limited Partnership, a Maryland limited partnership
("MHLP"), a stockholder of the Company. In February 1995, at the time of the
establishment of Baltimore Medical Group, LLC, MHLP was formed and BMGPA
physicians transferred certain assets of their medical practices, excluding
laboratory and other ancillary assets, to MHLP in exchange for an aggregate
consideration of (i) limited partnership interests in MHLP that are currently
equal to approximately a 25.5% interest in MHLP, (ii) approximately $23,500 in
cash, and (iii) promissory notes with an aggregate face value of approximately
$471,200. In order to comply with applicable regulatory requirements, the
laboratory and other ancillary assets were transferred directly to Baltimore
Medical Group, LLC by BMGPA. MHLP simultaneously conveyed substantially all of
its remaining assets to the Company, and the Company issued to MHLP 1,100,000
shares of the Company's Class B Common Stock. As a result of a subsequent stock
split, MHLP now holds 2,200,000 shares of the Company's Class B Common Stock.
The physician owners of BMGPA became members and employees of Baltimore Medical
Group, LLC, and have continued the practice of medicine
    
 
                                       23
 
<PAGE>
   
through Baltimore Medical Group, LLC. The Company and Baltimore Medical Group,
LLC entered into a PSO Agreement pursuant to which the Company provides Managed
Care contracting and practice management services to Baltimore Medical Group,
LLC, leases to Baltimore Medical Group, LLC, the assets used by the physicians
in their medical practices, and provides non-medical employees to Baltimore
Medical Group, LLC. See "Development of Integrated Health Care Delivery
System--Focus on Primary Care Physicians."
    
 
   
     Under the Partnership Agreement and other documents related to MHLP, shares
of the Company's Class B Common Stock held by MHLP will be distributed to the
partners of MHLP upon a change in control of the Company, including an
underwritten public offering, or other event of liquidation of MHLP. The General
Partner of MHLP is BMGGP, Inc., a Maryland corporation, which owns a one percent
(1%) interest in MHLP. The stockholders of BMGGP, Inc., are 17 of the initial
members of Baltimore Medical Group, LLC, and the 17 initial limited partners of
MHLP, including Drs. Rifkin, Kimmel, Nagel, LoPresti and Ancona. Accordingly,
the members of Baltimore Medical Group, LLC, indirectly own shares of the Class
B Common Stock through their limited partnership interests in MHLP and, for the
initial 17 members of Baltimore Medical Group, LLC, as stockholders of BMGGP,
Inc.
    
 
   
     Since the formation of Baltimore Medical Group, LLC and MHLP, additional
physicians have sold their medical practices and acquired limited partnership
interests in MHLP and membership interests in Baltimore Medical Group, LLC,
Carroll Medical Group, LLC, Cumberland Valley Medical Group, LLC or Doctors
Health Montgomery, LLC. In addition, such Equity Physicians have become
employees of one of these Core Medical Groups. In some instances, Equity
Physicians received shares of the Company's Class B Common Stock directly in
lieu of partnership interests in MHLP. Following the reorganization of BMGPA in
February 1995, the Company acquired 15 practices during calendar year 1995 for
an aggregate consideration of (i) limited partnership interests in MHLP that are
currently equal to approximately a 21% interest in MHLP, (ii) approximately
$78,300 in cash, and (iii) promissory notes with an aggregate face value of
approximately $572,800. From January 1, 1996 through October 4, 1996, the
Company acquired 26 additional practices for an aggregate consideration of (i)
limited partnership interests in MHLP that are currently equal to approximately
a 14.1% interest in MHLP, (ii) 304,000 shares of the Company's Class B Common
Stock, (iii) approximately $656,381 in cash, and (iv) promissory notes with an
aggregate face value of approximately $1,521,461.

     The Company is constructing its Integrated Health Care Delivery System by
acquiring the assets and/or managed care contracting rights of medical practices
throughout the Baltimore-Washington metropolitan area and contiguous regions.
    
 
   
     EXPANSION INTO CARROLL COUNTY, MARYLAND. In November 1995, the Company
acquired the practices of five primary care physicians and formed Carroll
Medical Group, LLC ("Carroll Medical Group") located in Carroll County,
Maryland. Like the majority of the Baltimore Medical Group, LLC physicians,
these doctors acquired cash and limited partnership interests in MHLP and became
members of and employed by Carroll Medical Group. Carroll Medical Group entered
into a PSO Agreement with the Company on terms substantially identical to the
Baltimore Medical Group, LLC PSO Agreement. In September 1996, an additional
physician joined Carroll Medical Group.
    
 
   
     EXPANSION INTO MONTGOMERY COUNTY, MARYLAND. In February 1996, the Company
entered into binding letters of intent to acquire the primary care practices of
21 physicians in Montgomery County, Maryland. The Company consummated
transactions involving nine physicians through October 4, 1996 and formed
Doctors Health Montgomery, LLC ("Doctors Health Montgomery"). The Company
expects to consummate the remaining twelve transactions in October and November
1996. Doctors Health Montgomery entered into a PSO Agreement with the Company.
    
 
   
     EXPANSION INTO ANNE ARUNDEL COUNTY, MARYLAND. In February 1996, the Company
entered into binding letters of intent to acquire the primary care practices of
nine physicians in Anne Arundel County, Maryland. The Company expects to
consummate these transactions in October 1996.
    
 
   
     EXPANSION INTO ALLEGANY COUNTY, MARYLAND. In May 1996, the Company
consummated the acquisition of five primary care physician practices located in
Cumberland, Maryland, which on May 1, 1996, formed the Cumberland Valley Medical
Group ("CVMG"). Like Carroll Medical Group and Doctors Health Montgomery, CVMG
entered into a PSO Agreement with the Company on terms substantially identical
to the Baltimore Medical Group, LLC PSO Agreement. The Company is establishing
an IPA in Allegany County.
    
 
   
     EXPANSION INTO WASHINGTON COUNTY, MARYLAND. The Company has established an
exclusive Managed Care contracting arrangement with Quality Healthcare IPA
("QHC"), an IPA representing approximately 19 primary care physicians in
Washington County, Maryland. Eleven of the 19 physicians have agreed to conduct
all managed care contracting through the Company and QHC on an exclusive basis.
Pursuant to the IPA agreement, the Company is the exclusive Managed Care
contracting entity on behalf of the IPA's PCPs, and is developing a network of
specialists.
    
 
   
     EXPANSION INTO HARFORD COUNTY, MARYLAND. The Company has established a
Managed Care contracting arrangement with a group of 11 primary care physicians
in Harford County, Maryland. Pursuant to the IPA Agreement, the Company is the
exclusive Managed Care contracting entity for Medicare managed care patients of
this IPA.
    
 
   
     EXPANSION INTO NORTHERN VIRGINIA. The Company has entered into a letter of
intent with an IPA based in Springfield, Virginia. Pursuant to the letter of
intent, the Company will form a Core Medical Group and an Exclusive IPA
consisting of primary care physicians to provide medical care throughout
Northern Virginia. As of October 4, 1996, the IPA had approximately 126 PCP
participating physicians, approximately 60 of whom have indicated an interest in
joining a Core Medical Group or conducting managed care contracting solely
through the Company. Completion of the transaction is subject, among other
things, to compliance with Virginia blue sky laws and due diligence.
    
 
   
     JOINT CONTRACTING ARRANGEMENTS IN BALTIMORE. The Company has entered into a
Contracting and Managed Care Services Agreement with an organization which
operates health care facilities in Baltimore City and employs and contracts with
approximately 42 physicians in Maryland. Under the arrangement, the Company acts
as the organization's exclusive contracting entity for Medicare managed care
contracts. The arrangement involves a sharing of managed care surplus and
losses.
    
 
   
     FORMATION OF CARDIOLOGY CORE MEDICAL GROUP. The Company has entered into a
letter of intent with the Board of Directors of a 16-physician cardiology
practice, providing services to patients in the Baltimore metropolitan area, to
acquire the practice assets pursuant to a merger. The practice would receive
shares of Class B Common Stock and the practice would become a separate Core
Medical Group dedicated to cardiology (the "Cardiology Core Medical Group"). The
Company believes that it is probable that the acquisition will be completed in
October or November 1996. The Company intends to acquire additional specialists
and create either stand-alone Core Medical Groups or integrate such acquired
specialists into existing Core Medical Groups.
    
 
   
     The Company expects it will continue to expand by increasing the number of
physicians in each Core Medical Group, forming new Core Medical Groups, entering
into Non-Exclusive and Exclusive IPA Agreements with physicians and pursuing
acquisition and expansion opportunities in the Baltimore and Washington
metropolitan area and surrounding regions.

OVERVIEW OF BUSINESS ACTIVITIES
 
   
     The Company's Integrated Health Care Delivery Network includes PCPs and
other physicians who transfer certain medical practice assets to the Company and
become employees of a Core Medical Group, such as Baltimore Medical Group. PCPs
may also join Independent Practice Associations ("IPAs"). The Company also
enters into network contracts with specialists who agree to provide services to
managed care patients referred by PCPs and, in certain cases, acquires the
medical practices of such specialists. A Network Physician who becomes employed
by a Core Medical Group agrees to conduct his medical practice only through the
Core Medical Group and to permit the Company to act as his exclusive agent for
the purpose of negotiating managed care risk and other contracts in which the
PCP must participate. The PCP's obligation to participate in managed care
contracts negotiated by the Company is set forth in the PCP's Employment
Agreement with the Core Medical Group and the PSO Agreement between the Core
Medical Group and the Company. If a PCP joins a Company-sponsored IPA, the PCP
agrees to participate in managed care contracts negotiated and administered by
the Company on either an exclusive or non-exclusive basis.
    
 
     When a physician becomes an employee of one of the Company's Core Medical
Groups, the Company transitions any primary care Managed Care contracts in which
the physician participates into the Company's group contract or the applicable
Core Medical Group contract if any is in effect with respect to that Payor. If
the Company or the Core Medical Group does not have a PCP group contract in
place with the Payor and the Payor allows the contract to be assigned to the
Company, the Company will maintain the contract on the physician's behalf under
the same contract terms. The reimbursement provisions under such contracts are
exclusively for primary care on either a fee-for-service or capitated basis.
   
 
    
   
     The Company negotiates a variety of risk-sharing arrangements with HMOs and
other Payors, including global capitation contracts (and sub-capitation
contracts) pursuant to which (i) such Payors pay the Company a fixed amount per
Enrollee per month and the Company is responsible for meeting all of the primary
and specialty care, hospital and certain other related health care needs (or
specified portions thereof) of such Enrollee and (ii) the Company pays PCPs and
specialists, hospitals and other providers within its network or those having
other contractual arrangements with the Company for providing the required
medical care. The ability of the Company to achieve and maintain profitability
will depend to a great degree on (i) reducing the incidence of high cost acute
care episodes, primarily through wellness, prevention initiatives and aggressive
care management, and (ii) negotiating compensation arrangements that result in
payments to the Company that exceed the cost of care by the Company to PCPs,
specialists, hospitals and other providers. The Company will seek to achieve
this result by negotiating reduced fee-for-service, sub-capitation and other
arrangements with PCPs, specialists, hospitals and other health care providers,
creating economic incentives for all Network Physicians and other providers with
whom the Company contracts to utilize specialists and hospitals prudently,
carefully monitoring the quality and cost of care provided to patients and
developing programs to promote wellness among patients.
    
 
     The Company intends to earn most of its revenues from sources other than
the primary care component of Global Capitated Contracts, such as the
non-primary care component of any capitation fees which are payable to the Core
Medical Group, revenues for other services provided by the Core Medical Group
that the Core Medical Group is not entitled to retain and amounts earned as a
bonus or shared risk distribution under managed care contracts. The Company may
negotiate and/or establish the amount of some of such revenue sources without
consultation with the Core Medical Group.
 
     The Company intends to offset most of the cost of its centralized patient
data and information systems through profits earned from contracting and
practice management services and through profits earned from successful
management of global capitation agreements with HMOs, rather than through
separate fees charged for specific information systems and management services.
 
   
     Physicians participating in the Company's networks may derive benefit from
the successful implementation of the Company's strategy in several ways. A
physician to whom Securities are issued in the various affiliation transactions
described elsewhere herein will benefit through the ownership of Securities if
the Company achieves and grows in profitability. A physician, whether or not he
becomes an owner of Securities, may also receive capitated income from the
Company's managed care contracts and may also receive cash bonus payments out of
the bonus pool established by the Company for Network Physicians.
    
 
   
     As of October 4, 1996, there were 694 Network Physicians in six regional
networks throughout the state of Maryland, including approximately 176 PCPs, 95
obstetrician-gynecologists and 423 specialist physicians. Of these,
approximately 90 were Equity Physicians who had transferred, or entered into
binding letters of intent or otherwise agreed to convey, certain practice assets
of their practices to the Company and become employees of Core Medical Groups.
As of such time, the
    
 
                                       27
 
<PAGE>
   
networks established by the Company were providing services in Central and
Western Maryland. As described in "Strategy--Expansion Strategy," the Company
intends to enter into selective medical practice acquisitions and other
contractual arrangements that will result in the Company operating in areas
beyond those in which it currently operates.
    
 
OPERATIONS
 
   
     The Company's operations to date have consisted of recruiting and acquiring
PCP and other physician's practices, negotiating and managing risk, capitated or
fee-for-service contracts with HMOs and other Payors, contracting with
individual specialists, specialist networks and IPAs, developing and
implementing a marketing program to convert Medicare patients from traditional
fee-for-service insurance to Medicare HMO programs, and providing billing,
accounting, legal, contracting support and care management services to its
Equity Physicians and certain Network Physicians. Beginning in February 1995
with respect to Baltimore Medical Group, December 1995 with respect to Carroll
Medical, May 1996 with respect to Cumberland Valley Medical Group, June 1996
with respect to Quality Healthcare IPA, September 1996 with respect to the
Doctors Health Montgomery Medical Group, and October 1996 with respect to the
Harford County IPA physicians, the Company has negotiated managed care contracts
with HMOs and other Payors on behalf of the PCP practices of such medical
groups. The Company also manages primary care IPAs in Central and Western
Maryland.
    
 
     The Company also maintains primary care only contracts on behalf of Network
PCPs under similar or improved non-risk contract terms. The reimbursement
provisions under such contracts are exclusively for primary care on either a
fee-for-service (FFS) or capitated basis. The Company currently maintains such
contracts for certain of its PCPs with Payors including Aetna, CIGNA, NYL Care,
Health Plus, Principal Healthcare of the MidAtlantic, Prudential, Blue
Cross-Blue Shield of Maryland, USA Health Network and Preferred Health Network.
The Company also has entered into new group fee-for-service contracts with
various Payors including Preferred Health Network, Metra Health, MAMSI, U.S.
Healthcare, USA Health Network, Employee Health Plan and John Hancock Health
Plan.
 
   
     To date, the Company has entered into two Medicare Global Capitation
Contracts and one commercial Global Capitation Contract with Payors and is
continuing to negotiate Global Capitation Contracts with additional Payors who
conduct business in the Baltimore and Washington metropolitan area and
surrounding regions. Under these risk contracts, the Company receives a
capitation payment and must provide Enrollees with primary care and certain
specialist and hospitalization services.
    
 
   
     In October 1995, the Company entered into a contract with
CareFirst--Freestate, an affiliate of Blue Cross-Blue Shield of Maryland
("CareFirst") pursuant to which the Company's PCPs provide medical services to
commercially insured Enrollees on a global capitated basis (the "CareFirst
Commercial Contract"). In this contract, the Company assumes risk for all
professional services and shares risk with CareFirst on institutional services.
    
 
   
     In February 1996, the Company entered into a Global Capitated Contract with
CareFirst pursuant to which the Company's PCPs provide medical services to
Medicare patients on a global capitated basis (the "CareFirst Medicare
Contract"). The Company also receives capitation payments to provide all covered
medical services to members enrolled in that HMO and assigned to one of the
Company's PCPs. The CareFirst Medicare Contract provides that the Company will
receive a capitation payment per patient per month and pay for all medical
expenses for covered medical services based upon rates developed by the U.S.
Health Care Financing Administration ("HCFA").
    
 
   
     In May 1996, the Company entered into a Global Capitated Contract with
Chesapeake Health Plan, an affiliate of United Healthcare, pursuant to which the
Company's PCPs will provide medical services to Medicare patients (the
"Chesapeake Contract"). Under the Chesapeake Contract, Chesapeake pays a
capitation payment (which may be increased based on enrollment) to the Company
on a per member per month basis based on the projected demographic distribution
of the patients enrolled with the PCPs, as well as the age, sex and Medicaid
eligibility of the subscribers enrolled with a Network PCP in Chesapeake's
Advantage 65 Medicare HMO programs. Under the contract, Chesapeake has delegated
to the Company the right to manage the utilization of medical services.
    
 
   
     As of October 4, 1996, the Company had approximately 33,000 Capitated Lives
derived from the participation of 45 of the Company's 176 Network PCPs in the
Managed Care contracts of the Company, its subsidiaries and affiliates. Of these
33,000 capitated lives, approximately 30,000 participate in the Company's
commercial Gatekeeper Capitation contracts, approximately 2,200 participate in
commercial Global Capitation Contracts, and approximately 800 in Medicare Global
Capitation Contracts. The Company derives no earnings from the commercial
Gatekeeper Capitation Contracts and plans to
    
 
                                       28
 
<PAGE>
   
convert the managed care lives in commercial gatekeeper contracts to Full Risk
and/or Global Capitated commercial contracts. (See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Sources of Revenues
and Earnings.") The Company believes that there are approximately 50,000
additional Medicare subscribers who are patients of the Company's Network PCPs.
The Company's ability to derive earnings from any of its capitated lives is
affected by whether the Network Physician is a member of a Core Medical Group or
a participant in an IPA.
    
 
   
     The Company has developed and is implementing a marketing program in
conjunction with CareFirst and Chesapeake to enroll Medicare-eligible patients
in CareFirst's and Chesapeake's Medicare HMOs, respectively. The Company may
participate in other commercial and Medicare risk programs operated by other
HMOs and other Payors on a basis similar to the CareFirst and Chesapeake
arrangements.
    
 
   
     The Company's operations also include the recruitment of specialists into
Core Medical Groups and/or developing a network of preferred provider
specialists who are paid on a discounted fee-for-service or subcapitated basis.
As of October 4, 1996, the Company had access to approximately 423 specialists
in its network pursuant to direct or indirect contractual arrangements. The
Company expects that an increasing percentage of the specialist networks will
enter into contracts that provide for compensation on a capitated basis. The
Company currently has capitated payment arrangements with Womancare IPA, a
Company-developed network of 95 physicians providing obstetrical/gynecological
services, and with outside providers of radiology and laboratory services. Under
the Company's agreements with the respective specialty network, the
participating specialist providers provide services to the Company's members
referred by a Network Physician, and the network is reimbursed on a capitated
basis. The Company owns a majority interest in Womancare IPA.
    
 
   
     In addition, the Company's operations include the provision of traditional
management services to the individual medical practices of each Core Medical
Group, including administrative, legal and accounting services, lease
negotiations, and financial, billing and collection services. As of October 4,
1996, the Company has installed its information systems in 36 PCP offices to
facilitate development of a unified information system for referral management,
billing and collection activity, utilization review, and group purchasing and
risk management programs. As of October 4, 1996, the Company had assumed
responsibility for the billing operations of 34 PCP practices, representing 62
physicians, and one laboratory, which provides services to 31 physicians.
    
 
     As of the date of this prospectus, the Company has not yet conducted
material operations through Doctors Health System-Medalie Equipment Corporation,
a wholly-owned subsidiary of the Company, except to transfer certain cardiology
equipment, to the subsidiary, or through Doctors Health System Primary Care IPA,
Inc., a wholly-owned subsidiary of the Company.

DEVELOPMENT OF INTEGRATED HEALTH CARE DELIVERY SYSTEM
 
   
     CONTRACTS WITH PHYSICIANS.
    
 
   
     The Company contracts with Network Physicians and other physicians in one
of several ways: (1) through the transfer of certain of the medical practice
assets and contracts to the Company, as a result of which the physician may
obtain, directly or indirectly, cash and/or an equity interest in the Company;
(2) through an Exclusive IPA arrangement, pursuant to which such physician
agrees to conduct all managed care contracting activity exclusively through the
Company and to take as patients any capitated patient referred by the Company up
to a certain level; (3) through a Non-Exclusive IPA arrangement, in which the
physician may contract with or through other IPAs but agrees to take all managed
care patients referred by the Company; or (4) a myriad of other contractual
arrangements involving an IPA, joint venture or other arrangement in which the
physician may contract with others and may also elect to accept or not any
patients referred by the Company. The Company's goal is to remain flexible and
to accommodate the needs of physicians in each local market.
    
 
     The Company also enters into contracts with group practice entities,
clinics and IPAs through joint venture relationships as well as the contractual
relationships described above. The use of any particular contractual arrangement
is influenced by a number of factors, including the needs of the physicians, the
type of practice in which such physicians are engaged, the geographic location
of the practice, financial considerations, regulatory concerns, and pre-existing
contracts.
 
   
     FOCUS ON PRIMARY CARE PHYSICIANS.
    
 
     Consistent with the Company's primary care-driven strategy, the primary
focus of the Company's contractual arrangements with physicians has been
establishing relationships with PCPs. Since the Company's inception, entities
have been formed or consolidated to conduct group medical practices as Core
Medical Groups. Each Core Medical Group is comprised of a group of physicians
under common management and with a common information system and provider number
and is
 
                                       29
 
<PAGE>
designed to provide a full and coordinated spectrum of medical services to
patients and meet Payors' needs. To date, Core Medical Groups have been formed
in five geographic markets in Maryland using a limited liability company
organizational structure.
 
   
     From February of 1995 to December 31, 1995, the Company assumed exclusive
management responsibility for and became the sole contracting entity for an
additional 15 PCP practices through Baltimore Medical Group, LLC, and Carroll
Medical Group, for a total of 32 PCP practices. Since December 31, 1995, the
Company assumed, or entered into binding letters of intent to acquire certain
assets and became the sole contracting entity for an additional 42 PCP
practices. Thus, as of October 4, 1996, a total of approximately 74 PCPs have
transferred their medical practice assets and became employees of the various
Core Medical Groups, or have entered into binding letter agreements to transfer
their medical practices and become employees.
    
 
     Although the details of each transaction may differ, the practice of the
Company upon establishment of a Core Medical Group is to enter into a Practice
Participation Agreement with the Core Medical Group and each of the Equity
Physicians who is a member of such Core Medical Group, pursuant to which the
following transactions occur:
 
   
     TRANSFER OF MEDICAL PRACTICES. Under the Practice Participation Agreement,
an Equity Physician transfers to the Company certain medical practice assets as
well as contract rights under certain business contracts of the medical
practice, to the extent that such rights are assignable. Although the form of
consideration paid to such Physicians may vary, typically the Physician receives
a combination of cash and Securities of the Company. For a description of such
Securities, see "Description of Capital Stock." The amount and type of
consideration payable to each Physician is determined by negotiation between
such Equity Physician and the Company. Such transactions consist of an
acquisition by the Company of certain tangible and intangible assets of the
medical practice, including contract rights, and the collection by the Company
of the accounts receivable of the Physician.
    
 
   
     EMPLOYMENT OF PHYSICIANS BY THE CORE MEDICAL GROUP. Each Physician enters
into an Employment Agreement with the Core Medical Group of which he is a
member. Typically, Employment Agreements have a term of 10 years, during which
time the Physician will be obligated to devote his full professional time to the
practice of medicine with, for and through such Core Medical Group. As an
inducement to sign the agreement and as an incentive to remain as an
employee-physician, each "full time" PCP also may receive additional shares or
options of Class B Common Stock. The Employment Agreement provides for the
payment of a base salary and benefits and for the eligibility of such Physician
to participate in distributions from a bonus pool (each, a "Core Medical Group
Bonus Pool"). Each Core Medical Group Bonus Pool is distributed by the
Management Committee of the Core Medical Group and rewards high clinical
quality, appropriate utilization, patient satisfaction and retention, and
general cooperation and attitude. The employed physician may be eligible to
participate in such distributions in such years in which such physician meets or
exceeds such standards as may reasonably be required by the Management
Committee. See "--Operation of the Core Medical Group".
    
 
   
     The base salary of PCPs in most Core Medical Groups is generally an amount
equal to the sum of certain revenues collected on behalf of the Core Medical
Group by the Company in respect of the physician services provided by such
physician, less the allocated costs attributable to the medical practice of, and
provision of related health care services by, such physician. The Company and
certain of the Physicians employed by Doctors Health Montgomery agreed that
Doctors Health Montgomery will provide base salaries to such Physicians. In
return for its commitment to provide financial resources, if necessary, for such
Physician's salaries, the Company will receive a percentage of the growth in
revenues generated by their medical practices and other fees.
    
 
     PSO AGREEMENT WITH THE CORE MEDICAL GROUP. The Company provides managed
care contracting and practice management services to the Core Medical Groups
(and indirectly to its Physicians) through 30 year PSO Agreements (with
automatic, renewable 10 year terms) entered into between the Company and each
Core Medical Group. The following is a summary of the principal provisions of a
PSO Agreement.
 
     The PSO Agreement typically gives the Company the exclusive right to
provide to the Core Medical Group (i) all of the non-medical management and
financial services, including provision of non-physician employees, office space
and other facilities, equipment, assets, goods and supplies, that the Core
Medical Group and its Physicians will use to engage in the practice of medicine
and (ii) other related services.
 
   
     Pursuant to a typical PSO Agreement, the Company is given discretion and
authority to manage and conduct the business affairs of the Core Medical Group
and is appointed the agent and attorney-in-fact of the Core Medical Group to
enable the Company to fulfill these functions. The Company negotiates for and
enters into agreements with Payors for health care services, including managed
care contracts providing for compensation on a capitated basis, that will
obligate both the Core
    
 
                                       30
 
<PAGE>
Medical Group and its Physicians to provide medical services at the levels of
compensation negotiated solely by the Company. The Company also negotiates for,
and enters into agreements with, other providers of medical services for the
provision of medical services to the Core Medical Group or to the patients of
the Core Medical Group and for the provision of medical services to such
providers by the Core Medical Group and its Physicians, all on terms and for the
compensation determined solely by the Company. The Company has a broad range of
financial responsibility and authority by the Core Medical Group pursuant to the
PSO Agreement, leaving the Core Medical Group with the right to manage only
those professional components of its business requiring a license to practice
medicine.
 
   
     PSO Agreements provide that the Company is entitled to an amount equal to
the difference between the cash it collects on behalf of the Core Medical Group
and each of its physicians in receivables which have been conveyed to the
Company and the amount paid out by the Company in respect of the business costs
and expenses of the Core Medical Group. The Company will pay that amount over to
itself in each month during which there is sufficient cash in the Core Medical
Group's accounts, in the discretion of the Company, to pay the amount after
satisfying all of the Core Medical Group's business costs and expenses,
including such reserves therefor as the Company deems appropriate, and including
all accruals for unpaid base salaries of the physicians of the Core Medical
Group for prior periods. The Company may reserve the right to charge separate
fees for additional services, as agreed between the Company and the Core Medical
Group.
    
 
   
     PSO Agreements with PCP Core Medical Groups provide that the Company may
pay to the Core Medical Group, as a Managed Care Incentive Payment, an annual
negotiated amount of up to 25% of the total amount of all Company net income
before taxes and bonuses, attributable to the provision of health care to the
Core Medical Group's managed care patients during each calendar year, not to
exceed, in the aggregate, 25% of the base salaries paid to all PCPs of the Core
Medical Group. Such payments are not required if the Company has not earned net
income during the applicable years. Such payments may be utilized by the Core
Medical Group to fund the Core Medical Group Bonus Pool in which the physician
employees of the Core Medical Group may participate. See "--Employment of
Physicians by the Core Medical Group." It is anticipated that the full amount of
any Core Medical Group Bonus Pool will be paid out by the Core Medical Group to
its physicians as bonuses in each year.
    
 
     PSO Agreements that will govern the Company's relationship with specialists
will typically provide for (i) a term of 30 years with automatic, renewable 10
year terms; (ii) a commitment among the specialist group and the Company to
develop innovative, risk sharing payment arrangements; and (iii) use of
commercially reasonable efforts to provide the specialist group with managed
care referrals. Such specialist PSO Agreements will also provide for payment of
a management fee consisting of a negotiated percentage of actual operating costs
of the specialist Core Medical Group (excluding compensation to the group's
Physicians) and a percentage of collections available after payment of operating
costs, the Company's operating cost percentage, and the physician compensation.

   
     All of the PSO Agreements in effect have terms of 30 years (with automatic
10 year renewals) and generally may be terminated prior to expiration of its
term only under limited circumstances. Generally, absent insolvency, malfeasance
or a material uncured breach, the PSO Agreement cannot be terminated by the
Company or the Core Medical Group.
    
 
   
     OPERATION OF THE CORE MEDICAL GROUP. Each physician joining a Core Medical
Group enters into an Operating Agreement or similar agreement with each of the
other physicians in the Core Medical Group. Pursuant to the Operating Agreement,
the business and affairs of the Core Medical Group are managed under the
direction and control of a Management Committee, one of whom is the Chief
Executive Officer of the Company (or his designee) serving EX OFFICIO. The
Management Committee has the power, among other things, to determine the amount
of any or all bonuses payable pursuant to the Core Medical Group Bonus Pool
which it delegates to a Bonus Committee. The Members of the Management Committee
are elected by the affirmative vote of the Physicians of the Core Medical Group
(other than the Company designees). The Bonus Committee also establishes, in
consultation with the Company and the bonus committees of other Core Medical
Groups, practice protocols.
    
 
   
     INDEPENDENT PHYSICIAN ASSOCIATIONS.
    
 
     The Company has expanded its network by contracting with physicians in a
variety of ways through IPAs in which IPA Participant Physicians authorize the
IPA to negotiate service contracts on their behalf. In some cases, the Company
contracts with or through an existing IPA, while in other cases the Company
assists physicians who may wish to establish an IPA. The models utilized by the
Company involving IPAs consist of Exclusive IPAs, pursuant to which a physician
is obligated to conduct all managed care contracting through the Company,
Non-Exclusive IPAs, pursuant to which a physician may contract for managed care
with others but agrees to take all patients referred by the Company, and other
contractual arrangements which may involve a physician contracting for managed
care through others or choosing to accept or deny patients

                                       31
 
<PAGE>
referred by the Company. In some cases, the Company may issue Securities as
incentives for physicians to enter into Exclusive IPA Agreements. The Company
may also issue Securities as compensation for the recruitment of physicians to
join the Company's Core Medical Groups or Exclusive IPAs.
 
   
     COMPANY CREATED IPAS; PREVIOUSLY EXISTING IPAS: The Company may assist in
the creation of an IPA or may contract with a previously existing IPA or
independent medical group. In the case of previously existing IPAs or groups, in
addition to being subject to the various types of contractual arrangements
discussed below to which the Company is a party, the IPA and its network
physicians will also be subject to a previously existing participation agreement
among the previously existing IPA and its network physicians. In such cases, the
previously existing IPA also enters into a network agreement with the Company
which governs the contractual relations between the IPA and the Company. The
network agreement will contain provisions unique to the situation of each
existing IPA with which the Company contracts but should typically contemplate
the provision of various management services by the Company to the IPA and the
appointment of the Company as the IPAs agent and attorney-in-fact for the
purpose of negotiating managed care contracts with risk sharing arrangements for
the IPA on an exclusive or non-exclusive basis and providing other services such
as billing and information systems.
    
 
   
     ORGANIZATION OF THE IPA: The IPA is typically organized as a corporation or
limited liability company. Each of the IPA Participant Physicians enters into an
operating agreement among each of the other Participant Physicians in the IPA.
Pursuant to such operating agreement, each Participant Physician will agree to
be bound by the by-laws of the IPA which contain substantive requirements for
participation in the IPA.
    
 
   
     EXCLUSIVE IPAS: The IPA Participant Physician enters into an Exclusive IPA
Agreement with the Company and the IPA in which he participates, pursuant to
which the Company markets the physician to Payors, and includes the physician in
its provider network. The IPA Participant Physician may choose to participate in
Exclusive IPA Agreements for either Medicare or commercial products offered by
HMOs with whom the Company contracts, pursuant to which such physician agrees to
contract exclusively with the Company for Medicare or commercial managed care
contracts, respectively. As of the date of this Prospectus, 42 physicians were
participating with the Company's Exclusive IPAs. Although there can be no
assurances, the Company expects that additional physicians will commit to
participate in Exclusive IPAs.
    
 
   
     Under an Exclusive IPA Agreement, an initial primary care base capitation
rate and risk-sharing arrangements are negotiated between the Company and the
IPA. The IPA Participant Physician may also be eligible to participate in a
bonus pool. A one-time incentive payment, or periodic panel growth and managed
care bonuses which may include cash or Securities, may also be payable by the
Company pursuant to an Exclusive IPA Agreement. Further, the agreement may
contain a practice option, pursuant to which the physician may elect, subject to
the satisfaction of certain conditions, to sell his or her medical practice to
the Company.
    
 
   
     NON-EXCLUSIVE IPAS: The IPA Participant Physician enters into a
Non-Exclusive IPA Agreement with the Company and the IPA, pursuant to which the
Company markets the physician to Payors under capitation contracts and includes
the physician in its provider network. The physician reserves the right to
contract directly with HMOs or other Payors, and to participate in other IPAs,
but usually agrees to accept managed care patients referred by the Company, up
to agreed-upon levels. Other provisions of the Non-Exclusive IPA Agreement may
be similar to the provisions of the Exclusive IPA Agreement.
    
 
   
     JOINT VENTURE ARRANGEMENT. The Company has entered into a Contracting and
Managed Care Services Agreement with an organization which operates healthcare
facilities in Baltimore City, and employs and contracts with approximately 42
physicians in Maryland. Under the arrangement, the Company acts as the
organization's exclusive contracting entity for Medicare and Medicaid managed
care contracts. The arrangement involves a sharing of Managed Care surplus and
losses between the parties.
    
 
     OTHER CONTRACTUAL ARRANGEMENTS. Although other contractual arrangements may
take a variety of forms, generally these arrangements involve the IPA
Participant Physician entering into an agreement with the Company pursuant to
which the Company markets the physician to Payors but the physician reserves the
right to participate in other IPAs and to determine whether to accept managed
care patients referred by the Company.
 
     CONTRACTING WITH SPECIALISTS, HOSPITALS AND OTHER HEALTH CARE PROVIDERS
 
     The Company contracts with specialists, hospitals and other providers of
health care services as part of its effort to develop an integrated health care
delivery network.
 
   
     CONTRACTING WITH SPECIALISTS: The Company contracts with specialist
physicians for the provision of services to the Company and the Core Medical
Groups in a variety of ways, generally consisting of employment in a Core
Medical Group,
    
 
                                       32
 
<PAGE>
or contractual arrangements involving reduced fee-for-fee service or
sub-capitated arrangements. Other than employment in a Core Medical Group and
the formation of a cardiology Core Medical Group (see "Business--History of the
Company--Formation of Cardiology Core Medical Group"), arrangements with
specialists typically have terms of between one and five years. Specialists may
under appropriate circumstances also receive an equity interest in the Company.
 
   
     CONTRACTING WITH HOSPITALS AND OTHER PROVIDERS: The Company contracts with
hospitals ("Participant Hospitals") and other health care providers to
participate in its managed care networks. The Company envisions that many of its
arrangements with Participant Hospitals may involve "key hospital" arrangements.
The Company and the Participant Hospital will enter into a Hospital
Participation Agreement ("Hospital Participation Agreement"), pursuant to which
the Company will agree to make the hospital the referral hospital of choice for
specified categories of managed care patients and specified categories of
service. The Participant Hospital must meet cost and quality standards and agree
to cooperate with the Company in the implementation of utilization review, to
include preadmission guidelines and processes, patient care and cost tracking,
information exchanges and management reporting systems and the development of
innovative pricing arrangements. The Company also negotiates contractual
arrangements with other health care providers (for example, home health care
aides) as needed to deliver quality and cost-effective service to patients.
Although the term of such arrangements would vary, the Company expects to
negotiate discounted fee-for-service or sub-capitated arrangements with such
providers.

PHYSICIAN RECRUITMENT
 
   
     The Company recruits physicians through direct marketing efforts, Core
Medical Groups, and IPAs. The Company has a physician recruitment staff managed
jointly by the Company's Chairman, who is Director of Development, and the
Executive Vice President of Strategic Planning. The Company also employs a
Director of Recruiting, recruiting assistants and other staff. The Company also
recruits PCPs through relationships with current Core Medical Group physicians,
IPA Participants and other contacts. The Company also seeks assistance from
recruiting consulting arrangements. Such recruiting consultants provide the
Company with access to potential Network Physicians.
    
 
MANAGED CARE CONTRACTING
 
   
     CONTRACTS WITH PHYSICIANS, HOSPITALS AND OTHER PROVIDERS OF HEALTH CARE.
    
 
     As discussed above in "--PSO Agreement with the Core Medical Group" and
"--Independent Practice Associations," the Company is authorized to negotiate
for and enter into agreements with Payors for health care services, including
managed care contracts providing for compensation on a capitated basis, that
will or may obligate Core Medical Groups and their respective physicians, IPAs
and their respective IPA Participant Physicians and other physicians to provide
medical services at the levels of compensation negotiated solely by the Company.
Further, as described above in "--Contracting with Specialists, Hospitals and
other Health Care Providers," the Company is also authorized to negotiate for
and enter into agreements with Payors for the provision of services available
from such providers.

     The Company's goal is to enter into shared risk arrangements with HMOs and
other Payors and to enter into full capitation/full risk arrangements with such
Payors. The Company believes that its capabilities in information systems and
care management will allow it to operate successfully and manage patient care in
a rapidly changing environment. See "Control of Patient Data and Information
Systems." The Company believes that the access to the Company's information
management systems and bonus payments for Physicians in Core Medical Groups and
IPA Participant Physicians in IPAs will allow such physicians to exercise
appropriate control over the cost of health care, providing better care at lower
overall cost. See "--PSO Agreement with the Core Medical Group" and
"--Independent Practice Association."
 
   
     CONTRACTS WITH PAYORS.
    
 
     The Company enters into contracts with Payors on behalf of Network
Physicians. Global Capitated Contracts typically obligate the Company to provide
and pay for all physician services (except for negotiated carve-outs) and, in
certain contracts, hospital and ancillary services for a percentage of the
premium or a fixed capitated amount. The Company then subcontracts with
physicians and other health care providers to provide the required services in
compliance with the Company's care protocols when applicable. The payment from a
Payor to the Company is typically calculated based on the number of Members of
the HMO enrolled with the Company's PCPs. Such Payor contracts generally have
terms of approximately one year and, after the initial term, are renewable for
one-year terms unless canceled by either party. In its Payor contracts, the
Company currently attempts to assume risk for all services, except mental health
and pharmacy. Eye care, home health and durable medical equipment (DME) also may
be carved out of the Company's risk due to more competitive terms for these
services being available to Payors based on their existing national
relationships. The Payor in each contract also retains a percentage of the
premium to perform marketing, enrollment and some administrative services.
 
   
     In entering into or renewing Payor contracts, the Company considers a
number of specific factors which affect capitated rates, the amount of the
shared risk and scope of covered services for which the Company is responsible.
These factors include, but are not limited to, the demographic risk profile of
the enrollee pool, the premium received by the Payor, prior financial
experience, cost and availability of stop-loss protection and an understanding
of the fee-for-service equivalent charges. In addition, the Company will work
with certain HMOs to establish preferential and/or partnership type
relationships in which incentives are provided in the contract to reward the
Company for accepting and retaining a high number of the plan's Enrollees. In
undertaking this process, the Company analyzes pertinent data in order to assess
the providers' contractual and economic opportunity and exposure, and then
conducts the negotiations on behalf of the physician networks.
    
 
CONTROL OF PATIENT DATA AND INFORMATION SYSTEMS
 
     The Company recognizes the need for advanced information systems and
technology to allow it to operate successfully and manage patient care in a
rapidly changing environment. A significant investment has been made and will
continue to be made in systems that support the comprehensive automation of
traditional physician office functions, such as patient flow, electronic medical
records, and billing and collections.
 
                                       35
 
<PAGE>
     The Company's information systems strategy consists of using sophisticated
hardware and software to (i) monitor PCP referrals to specialists, hospitals and
other providers; (ii) collect information regarding PCP compliance with medical
care protocols; (iii) allow physician offices to use Company-installed hardware
for billing through the Company's billing and claims management staff; and (iv)
eventually provide the Company and its care management staff with direct
computer access to hospitals in order to facilitate quality and cost-effective
care of Core Medical Group patients.
 
   
     The Company believes that its information systems will encourage exchange
of information among the Company's utilization review and care management staff
and physician practices, hospitals and other providers in the Company's provider
network to allow the Company to react promptly to changes in patient care
requirements, costs and utilization issues. The Company makes its information
systems available to all Core Medical Groups and Equity Physicians currently
participating in its networks and will make such systems available on a uniform
basis to other providers when they meet certain threshold requirements, while
also tailoring the system to meet unique needs of individual medical practices
to best serve the patients.
    
 
CARE MANAGEMENT
 
     The Company seeks to promote the wellness of patients, control costs,
encourage patient satisfaction and provide better integrated health care with
services received in the health care system through its utilization review,
referral management and care management program. These programs seek to control
the cost of medical care through monitoring the appropriateness of inpatient
hospital admissions, referrals to specialists and use of ancillary services by
the Company's care management staff.
 
     The Company's care management program also focuses on patient satisfaction
and cost savings by identifying patients whose diagnosis will require
significant medical care. Staff care managers coordinate all aspects of the care
of such patients, including development of a care plan in coordination with the
patient's primary care physician, by evaluating whether a particular treatment
is appropriate, whether there are alternate sites to provide the treatment, and
the availability of community resources to meet treatment needs. Management
believes effective care management will assist PCPs and other health care
professionals to slow the progression of the disease, ensure patient compliance
with the required treatment, reduce hospital admissions and lengths of stay, as
well as improve patient satisfaction. The Company believes that integrated
health care, with the PCP at its core, is both less expensive and provides
better health care for the vast majority of patients.
 
     The Company employs 17 care management personnel with nursing, social work
and other patient care and management experience to assist in coordination of
quality health care for a potential population of 80,000 members.
 
COMPETITION
 
   
     The Company's provider network competes with other provider networks and
medical groups, including those established by hospitals and other individual
physicians, and IPAs in obtaining managed care contracts with health maintenance
organizations and other Payors. The competitive factors that the Company
encounters include the number of physicians in each group, geographical coverage
of Network Physicians, the quality of care that can be provided to the Payors'
enrollees, and the ability to effectively manage care. The Company believes that
it can successfully compete with other entities seeking managed care contracts
with Payors because of the Company's large number of Network Physicians, thereby
providing Payors with an extensive network of providers to offer the Enrollees
of the Payors with whom the Company contracts. The Company also has an
increasing geographic coverage of Network Physicians with extensive coverage in
the Baltimore metropolitan area and Core Medical Groups (either existing or with
letters of intent) or IPAs in Allegany, Carroll, Anne Arundel, Harford, and
Montgomery Counties. However, a large number of physicians remain who may join
other provider networks and who may be competing for managed care contracts. The
Company also believes it can effectively compete with other networks because it
was one of the first established physician owned networks in Maryland, although
other provider networks in the region have recently been developed and the
Company expects others to be established.
    
 
     The Company competes with certain HMOs, other Payors, other provider
networks, medical groups, and hospitals in acquiring physician practices.
Further, large established traditional indemnity insurance companies also are
entering the managed care field and may compete with the Company in acquiring
physician practices and developing physician networks. Competitive methods
include the type and amount of compensation offered to physicians in exchange
for their practices, the level of clinical autonomy afforded the physician,
terms of employment arrangements, the level and extent of care management
imposed on the physician, and the types of management services that will be
provided to physicians. The Company believes it can effectively compete with
other groups in acquiring physician practices because the Company is driven by
 
                                       36
 
<PAGE>
primary care physicians and primary care strategies. Although other entities may
offer cash consideration for physician practices in amounts greater than the
Company, the Company believes that offering an equity interest in the Company to
its physicians provides an incentive of ownership which will encourage the
implementation of managed care. The Company believes its physician ownership
will attract greater numbers of physicians to its network, and because of the
significant percentage of the Company which is owned by physicians, such
physicians will be better able and more willing to implement managed care.
Further, the Company believes that it provides its Network Physicians with
greater clinical autonomy than may be offered by hospitals, HMOs or insurance
companies.
 
     The Company also will compete with other management companies providing
management services to physicians. While many of these companies have greater
marketing and financial resources than the Company and may be better able to
provide services to its health care providers, the Company will provide
comprehensive business management services to its Equity Physicians and certain
of its other Network Physicians, including administrative, legal and accounting
services, billing and collection services, referral management, utilization
review, and computer systems and training, thereby providing such physicians
more time to devote to the practice of medicine. See "Risk
Factors--Competition."

corporate names "Doctors Health System Managing Quality Health Care", "Doctors
Health, The Sure Sign of Caring", and "WomanCare".
    
 
LEGAL PROCEEDINGS
 
     The Company is a party from time to time in lawsuits incidental to its
business. The Company is not currently subject to any material legal
proceedings.
 
REGULATION
 
     Both the health care business generally and the activities of the Company,
including those by or with managed care entities, the Core Medical Groups and
their employee physicians, are subject to extensive and pervasive Federal and
state regulation. The Company believes that its operations are in material
compliance with applicable laws and regulations, as currently interpreted and
applied. However, federal and state laws and regulations, including the federal
"fraud and abuse" laws, federal and state law restrictions on physician self
referral, and the pervasive regulation of the activities of managed care
entities, tend to be broadly written and lack extensive judicial interpretation.
There can be no assurance that a review of the Company's operations and
structure by regulatory authorities or courts might not result in a
determination that could adversely affect the Company. Moreover, the regulatory
environment in which the Company operates has changed materially over the past
ten years, and future changes are likely, some of which could restrict the
Company's existing structure or business relationships, limit its growth, or
inhibit its financial operations or opportunities for success.
 
   
     MEDICARE AND MEDICAID FRAUD AND ABUSE LIMITATIONS.
    
 
     Under the Social Security Act, it is a felony, punishable by imprisonment
or fines or both, to make false statements of material fact in Medicare or
Medicaid billing or benefit determination matters, or knowingly and willfully to
offer, pay,
 
                                       37
 
<PAGE>
solicit or receive, directly or indirectly, any form of remuneration in exchange
for referring any patients or arranging or furnishing any item or service
reimbursable by the Medicare or Medicaid programs (the "fraud and abuse" or
"anti-kickback" rules). Criminal prosecutions are controlled by the Justice
Department. The Department of Health and Human Services ("DHHS"), through the
Office of the Inspector General (the "OIG"), may bring civil actions for
monetary penalties and to exclude individuals from participating in the Medicare
or Medicaid programs for violations of the fraud and abuse rules. The fraud and
abuse rules are broadly drafted, and have been broadly interpreted by courts.
Read literally, the fraud and abuse rules may prohibit not only kick-backs but
many legitimate business arrangements and joint venture activities. Many States
have adopted rules similar to the fraud and abuse rules. While the Company
believes that its activities do not violate the fraud and abuse rules, there can
be no assurance that federal or state regulators might not challenge some of the
Company's activities.
 
     Concerned that legitimate business arrangements were being stifled by the
fraud and abuse rules, Congress directed DHHS to promulgate regulations which
establish strictly defined "safe harbor" exceptions to the fraud and abuse
rules. Initial safe harbors were adopted in July 1991, and others have been
adopted and proposed from time to time. Some of these safe harbors are
applicable to the activities of the Core Medical Groups, its employee
physicians, and the Company, including provisions related to space and equipment
leases, personal service and management contracts, the sale of practices, bona
fide employment relationships, group practices and managed care contracting
activities. All lease and services agreements must be in writing, have terms of
at least one year, specify services to be provided, require payment consistent
with fair market value in arms length transactions which is not determined by
taking into account the volume or value of referrals of Medicare and Medicaid
business. The Company believes that its lease, management and physician practice
acquisition activities generally fall within the safe harbors. However, no
independent appraisal or fairness opinion concerning the fair market value of
such leases or services agreements or the reasonableness of the consideration
received by the Company therefor has been secured, and there can be no assurance
that federal or state regulators might not challenge some of the transactions or
practices of the Company. Failure to comply with a safe harbor exception with
respect to a transaction does not itself result in, or constitute a violation
of, the fraud and abuse rules.
 
   
     FEDERAL AND MARYLAND LAW REGARDING RESTRICTIONS ON PHYSICIAN SELF-REFERRAL.
    
 
     Maryland law and Federal law, generally referred to as the "Stark II"
legislation, as well as the law of some other states in which the Company may
operate in the future, prohibit "physician self-referrals," which may be defined
generally as referrals to another provider by a physician with a financial
interest in the provider. If a physician has a financial interest in, including
a direct or indirect ownership or investment interest, or a compensation
arrangement with a provider (including the physician's own Core Medical Group),
and no exception is applicable, the physician may not refer to the provider, and
neither the physician nor the provider may bill for any service rendered
pursuant to a prohibited self-referral. The fundamental difference between the
fraud and abuse rules and Stark II is that the former require some form of
intent to induce referrals to support a finding of violation, while Stark II
makes intent irrelevant. Under Stark II, if a physician refers a Medicare or
Medicaid patient or test to an entity in which he or she has a financial
interest, and if no exception applies, a violation has occurred.
 
     Stark II extended a prior ban on physician self-referral on laboratory
services ("Stark I") to a broad list of designated health services payable under
Medicare and Medicaid, including radiology and other diagnostic services,
radiation therapy services, physical and occupational therapy, durable medical
equipment, enteral and parenteral supplies, equipment, orthotics, outpatient
prescription drugs, home health services, and inpatient and outpatient hospital
services. If a prohibited self-referral occurs in Maryland, where the Company
currently operates, and such self-referral is not within an exception, (i)
neither the patient nor the Payor may be billed; (ii) Payors can recover all
amounts previously billed and paid in respect of non-excepted self-referrals;
and (iii) the referring physician and the provider are jointly and severally
liable to repay any amounts paid in respect of non-excepted self-referrals.
Federal law also imposes substantial monetary (up to $15,000 for each prohibited
referral and up to $100,000 for participating in a "circumvention scheme") and
other penalties for violations, including possible exclusion from the Medicare
and Medicaid programs.
 
     The Maryland statute and Stark II have been recently enacted and there is
considerable uncertainty concerning how they will be interpreted, including
specifically how broadly the exemptions and exceptions to their application will
be applied. Regulations applying to Stark I and applicable to some, but not all,
of Stark II have recently been adopted. The Core Medical Groups, and the Equity
PCPs, as well as other entities that contract with the Company through
arrangements similar to the IPA arrangements described above, will have both an
ownership interest in and a compensation arrangement with the Company, and the
physicians will have similar relationships with the Core Medical Groups and with
IPAs. Physicians will refer
 
                                       38
 
<PAGE>
patients among themselves within their practices and as part of the managed care
networks which the Company will establish. The Company believes that it is not
an entity to which referrals can be made, and that the referrals of patients by
participating physicians within the managed care networks managed by the Company
should fall within one or more of the exceptions permitted by Stark II and the
state self referral laws. Future regulations, statutes or interpretations might
require the Company to restructure its relationships with the Core Medical
Groups and other managed care networks, and violation of Stark II by the Company
or its Core Medical Groups could result in significant fines and financial
losses which could adversely affect the Company.
 
   
     PROHIBITION AGAINST FEE SPLITTING.
    
 
     Physicians must be licensed in order to practice medicine. Maryland law,
the law of many other states, and the ethical rules of the American Medical
Association prohibit fee splitting, which is generally defined as a physician
soliciting professional patronage through an agent or a person who profits from
the act of the represented physician, or from paying or agreeing to pay any sum
to any person for bringing or referring a patient. Similar language in other
states has been coupled with the corporate practice of medicine doctrine to
prohibit or question management agreements pursuant to which non-physicians in a
management company obtain substantial financial benefits from a physician
practice. The Company will operate as a management company on behalf of the Core
Medical Groups and, potentially, other physician groups, and will enter into
managed care contracts with managed care companies in which the Core Medical
Groups and other physician groups participate. The Company believes that, under
the currently applicable interpretations of Maryland law and ethical rules
applicable to the practice of medicine in Maryland, the activities of the
Company under its management agreements are not in conflict with or violation of
any applicable legal or ethical requirements imposed on the practice of
medicine.
 
   
     ANTITRUST AND INSURANCE CONCERNS.
    
 
     The Core Medical Groups and the physicians who are members of the IPAs with
which the Company contracts are separate legal entities and may be deemed to be
competitors subject to a range of antitrust laws which prohibit anti competitive
behavior, including price fixing, division of markets, and group boycotts and
refusals to deal. The managed care network contracting activities which are the
Company's main business are susceptible to antitrust challenge. The Department
of Justice and the Federal Trade Commission have published guidelines for the
formation and activities of managed care contracting networks, and the Company
intends to comply with those guidelines in developing networks. However, there
is no assurance that review of the Company's business by courts or state or
federal regulatory authorities, or private antitrust challenges by competitors,
will not result in a determination that could adversely affect the operation of
the Company and its managed care networks.
 
     States heavily regulate the activities of insurance companies and health
maintenance organizations. The Company is not registered as an insurance company
or HMO with any state, and does not believe that its activities constitute the
business of insurance, but there can be no assurance that state regulators might
not challenge some of the Company's present or future activities as falling
within the business of insurance, or that the Company might not be required to
become a licensed insurer at some time in the future. See "Risk
Factors--Regulation." Some states impose requirements on entities which contract
with HMOs and insurers, and such requirements might impose significant costs on
the business of the Company, which might adversely affect the business or
operations of the Company.
 
   
     FUTURE REGULATION.
    
 
     The health care industry is subject to extensive regulation and is in a
state of change. A variety of legislative proposals substantially to reform the
payment for and delivery of health care services have been presented at both the
Federal and state levels in the past several years. Among issues addressed by
such legislation have been means to control or reduce public and private
spending on health care, to reform the payment methodology for health care goods
and services by both the public (Medicare and Medicaid) and private sectors,
limitations on federal spending for health care benefits, and universal access
to health care. Reform proposals may continue to be considered by the
legislatures of both the United States and states in the future; however, it is
uncertain what proposals may be made in the future or whether any such proposals
will be enacted as law. Elements of reform proposals, if acted upon by Federal,
State or private Payors for health care goods and services, may result in
reduced or limited payment for health care services or in controlled or limited
access to certain health care services generally. There can be no assurance what
effect such reforms may have on the business of the Company, and no assurance
can be given that any such reforms would not have an adverse effect on the
Company's revenues and/or earnings. There can be no assurance that future
statutes or regulations, or future interpretations of existing statutes or
regulations, will not make it difficult or impossible for the Company to conduct
its business in the manner presently contemplated and described herein. In any
such event, the management of the Company will attempt to restructure the
business of the Company in order to comply
 
                                       39
 
<PAGE>
with any such new statutes, regulations or interpretations. There can be no
assurance, however, that the Company will be able to do so, or that such
restructuring will not adversely impact the business of the Company.

     STOCK OPTION PLANS.
    

   
     OMNIBUS STOCK OPTION PLAN:
    

     On August 9, 1995, the Company adopted the Omnibus Stock Option Plan (the
"Omnibus Plan"). All employees, officers, directors and other key contributors
to the Company may participate in the Omnibus Plan. The aggregate number of
shares of Common Stock which may be issued under the Omnibus Plan is 6,175,000.
The Omnibus Plan authorizes the grant of options to purchase Common Stock
intended to qualify as incentive stock options or non-qualified options as well
as stock appreciation rights and restricted or unrestricted share awards. The
Omnibus Plan is administered by the Compensation Committee of the Board of
Directors which, subject to the provisions of the Omnibus Plan, has full
authority (i) to select the individuals to participate in the Omnibus Plan, (ii)
grant awards provided under the Omnibus Plan, (iii) modify, renew or extend
outstanding grants in accordance with the Omnibus Plan, (iv) interpret the
Omnibus Plan, and (v) adopt, amend or rescind rules and regulations for carrying
out the Omnibus Plan.

   
     The option exercise price for each option is determined by the Compensation
Committee, but in the case of incentive stock options shall not be less than
100% of the fair market value of the shares on the grant date and in the case of
non-qualified stock options shall be as determined by the Compensation
Committee. Incentive stock options may be granted only to employees of the
Company. The terms of each option may not exceed ten years from the grant date.
As of the date of this Prospectus, the Company has granted options to purchase
200,880 shares of Class A Common Stock under the Omnibus Plan and authorized the
issuance of additional options to purchase 5,000 shares of Class A Common Stock.
The exercise price of 130,880 of such options granted is $.01 per share, and
70,000 options have an exercise price of $11.00 per share. Of such options,
85,130 were granted on August 10, 1995, 33,250 shares were granted on October
18, 1995, 12,500 were granted on December 21, 1995, and 70,000 were granted in
May 1996. In April 1996, 2,500 options terminated due to termination of
employment as of June 1, 1996, 5,000 options were terminated June 30, 1996 due
to termination of employment, and 12,550 were terminated July 23, 1996 due to
termination of employment. As of the date of this Prospectus, 180,830 options to
purchase Class A Common Stock were issued and outstanding. The Company also has
granted options to purchase 117,000 shares of Class B Common Stock. 100,000 of
such options were issued in February 1995 at an exercise price of $.01 per
share, 5,000 of such options were issued as of October 1, 1995 at an exercise
price of $.01 per share, 3,000 of such options were issued on July 1, 1996 at an
exercise price of $.01 per share, 3,000 of such options were issued on September
12, 1996 at an exercise price of $15.00 per share, 2,000 of such options were
issued on October 1, 1996 at an exercise price of $15.00 per share and 4,000 of
such options were issued on October 3, 1996 at an exercise price of $15.00 per
share.
    

   
     Pursuant to the Omnibus Plan, the Company may award shares of Common Stock
to such participants and in such amounts and for such consideration, including
no consideration or such minimum consideration as may be required by law, as it
determines. Restricted shares may be issued pursuant to the Omnibus Plan,
subject to forfeiture if the restrictions do not lapse.
    

     The Company may also grant to any participant who holds an outstanding
stock option the right to surrender such option (to the extent such option is
otherwise exercisable) and to receive from the Company an amount equal to the
excess, if any, of

                                       44

<PAGE>
the fair market value of the Class A Common Stock with respect to which such
option is surrendered on the date of such surrender over the exercise price of
the surrendered option.

     Unless earlier terminated, the Omnibus Plan will terminate in 2005.

   
     ISSUANCE OF WARRANTS:
    

     On December 1, 1995, the Company issued to Medical Mutual Liability
Insurance Society of Maryland warrants to purchase 88,889 shares of Class A
Common Stock of the Company at an exercise price of $5.625 per share and issued
to each of Stephen Graham, Andrew Hamilton and John Dwyer, a director of the
Company, warrants to purchase 8,000 shares each of Class A Common Stock of the
Company at an exercise price of $11.25 per share.

awards to be made from the remainder of the Bonus Pool to employees of the

with Mr. Gold terminates in April of 2000, and unless notice of termination is

be entitled to all or a portion of his base salary and bonus in accordance with
the terms of his employment agreement.
 
   
     Pursuant to the employment agreement with Mr. Serini, Mr. Serini receives a
base salary of $175,000 per annum. Mr. Serini will be entitled to participate in
the Bonus Pool to the extent determined by the Chief Executive Officer, and the

be established upon agreement between Mr. Serini and the Chief Executive
Officer. For 1996, the Company and Mr. Serini have agreed upon a base bonus of
at least $50,000. Pursuant to the employment agreement, Mr. Serini received an
option to purchase 50,080 shares of Class A Common Stock. Mr. Serini may
exercise such option beginning on April 1, 1996, and will become fully vested in
such shares in April of 2000, or earlier under certain circumstances. The
employment agreement with Mr. Serini terminates in April of 2000, and unless
notice of termination is given will be automatically extended for succeeding 12
month periods. In the event that Mr. Serini is terminated by the Company other

bonus in accordance with the terms of his employment agreement.
    
 
     Pursuant to the employment agreement with Mr. Sanders, Mr. Sanders received
a base salary of $112,500 per annum. Pursuant to a stock option agreement, Mr.
Sanders received an option to purchase 22,550 shares of Class A Common Stock. In
connection with Mr. Sanders' resignation, 12,500 of such options were canceled.
The remaining 10,000 options are fully vested and exercisable. Mr. Sanders
resigned from the Company effective July 23, 1996 and his employment agreement
was terminated as of that date.
 
   
     Pursuant to the employment agreement with Dr. Rifkin, Dr. Rifkin receives a
base salary of $100,000 per year and at least 5% of the Bonus Pool. Dr. Rifkin
also received 100,000 shares of the Company's Class A Common Stock and was
granted an option to purchase an additional 100,000 shares of the Company's
Class B common stock that will vest upon the earlier to occur of (i) a Change in
Control of the Company, (ii) termination of his employment without cause or
under circumstances constituting "constructive termination", or (iii) December
9, 1996. The employment agreement with Dr. Rifkin terminates in April 2000, and
unless notice of termination is given, will be automatically extended for
succeeding 12 month periods on the same terms as previously in effect. In the
event that Dr. Rifkin's employment is terminated by the Company other than "for
cause," he will be entitled to all or a portion of his base salary and bonus in
accordance with the terms of his employment agreement.
    
 
   
     Pursuant to the employment agreement with Ms. Spoleti, Ms. Spoleti received
a base salary of $110,000 per year through June 4, 1996 and receives a Base

by the Company without cause, she will be entitled to accrued Base Salary and
benefits and an amount equal to the Base Salary that would have been payable

     COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION.
    
 
     Mr. Gold, the Company's President and Chief Executive Officer, is the only
officer or employee of the Company who serves on the Compensation Committee.
During the last completed fiscal year, the members of the Compensation Committee
were Messrs. Gold and Ellis, Ms. Dembiec and Dr. LoPresti. See " --Employment
Agreements" and "Certain Transactions."
 
STOCKHOLDERS AGREEMENT
 
     In December 1995, the "Management Stockholders" (consisting of Mr. Gold and
Drs. Rifkin and Kimmel), Medical Holdings Limited Partnership ("MHLP"), St.
Joseph Medical Center ("SJMC"), Medical Mutual Liability Insurance Society of
Maryland ("Med Mutual"), Med-Lantic Management Services, Inc., Genesis Health
Ventures, Inc. ("Genesis") and certain physician stockholders of the Company
(collectively, the "Stockholders") entered into a Stockholders Agreement, which
was amended in September 1996 (the "Stockholders Agreement") to which the
Company is also a party which governs certain aspects of the Company's
management plans and operations.
 
     Pursuant to the Stockholders Agreement, each of the Stockholders has agreed
to sell and transfer the stock of the Company held by them only pursuant to such
agreement. The Stockholders Agreement provides that upon the occurrence of the
termination of employment of any Management Stockholders (other than Drs. Kimmel
and Rifkin and except with respect to any "Involuntary Transfer" discussed
below), they will sell to the Company all of the stock then registered in the
name of such Management Stockholder. In the case of an "Involuntary Transfer"
(transfers defined in the Stockholders Agreement which include bankruptcy of a
Stockholder or transfer by divorce decree), the Company has the right for a 30
day period to purchase the stock held by such Stockholder. If the employment of
Mr. Gold is terminated, then the other Management Stockholders whose employment
with the Company has not been terminated have the option for a 60 day period to
purchase, in such proportions as they shall agree (or if they cannot so agree,
in proportion to their ownership of Class A Common Stock), on terms
substantially identical to those set forth in and for a price determined in
accordance with the Stockholders Agreement, the stock held by Mr. Gold. If all
of Mr. Gold's stock is not purchased by the other Management Stockholders, the
Company shall purchase all of Mr. Gold's stock. In such case the price that the
Company shall pay shall be as follows: (i) if Mr. Gold's employment is
terminated for cause (either pursuant to his employment agreement or pursuant to
law), or for reasons not constituting constructive termination, at a price equal
to the lower of acquisition cost or $1 per share, or (ii) if Mr. Gold's
employment is terminated by death, disability, the expiration of his employment
agreement, without good cause, or for reasons constituting constructive
termination under his employment agreement, then at an agreed upon price or at a
price determined through arbitration. In the event that the Company is required
to pay the price described in (ii), the Company, as a condition precedent to the
closing of such purchase, shall pay to SJMC and Med Mutual all of the dividends
then accrued but unpaid on the Series A Preferred Stock and Series B Preferred
Stock, respectively, plus all accrued and unpaid interest thereon.
 
     In the event that the employment of Drs. Kimmel or Rifkin is terminated (a)
by the Company for cause as defined under his employment agreement or under
applicable law, or (b) by such employee stockholder for any reason not
constituting "constructive termination" as defined in his employment agreement,
such Stockholder shall sell to the Company all of the stock then registered in
such Stockholder's name, at a price equal to the lower of his acquisition cost
per share or $1 per share; provided, that such provisions do not apply to (x)
the 100,000 shares held by Dr. Kimmel as of the date of the Stockholders
Agreement or, (y) the 100,000 shares held by Dr. Rifkin on the date of the
Stockholders Agreement, or (z) the 100,000 shares to be obtained by Dr. Rifkin
pursuant to his employment agreement. Upon the death or disability of either
Rifkin or Kimmel, such stockholder (or his personal representative) may offer to
the other Management Stockholders the option to purchase all of the Class A
Common Stock then held on terms substantially identical to those contained in
the Stockholders Agreement. If the employment of Kimmel or Rifkin is terminated
(a) by the expiration of his employment agreement, or (b) by the Company without
good cause, or (c) for reasons constituting "constructive termination" under
their employment agreements, then such Stockholder must sell to the Company all
of the Stock then held by such stockholder which is acquired after the date of
the Stockholders Agreement at a price to be agreed upon between the parties, or
failing such agreement, at a price determined through arbitration. In such
event, the Company must pay to SJMC and Med-Lantic all
 
                                       46
 
<PAGE>
of the dividends then accrued but unpaid on the Series A Preferred Stock and
Series B Preferred Stock, respectively, plus all accrued and unpaid interest
thereon.
 
     The Stockholders Agreement also provides that if the employment of Mr. Gold
is terminated without good cause or by Mr. Gold for reasons constituting
constructive termination, and there occurs a "Change in Control," of the Company
within 24 months following such termination, the Company must pay to Mr. Gold,
in addition to the purchase price, the value of his fair, allocative share of
any consideration that would have been payable to such terminated stockholder as
a result of such Change in Control.
 
     The Stockholders Agreement also provides that each of the holders of Class
A Common Stock agrees (i) to vote his shares to elect Stewart Gold, Alan Kimmel
and Scott Rifkin as three of the Company's Class A directors for as long as
their respective employment agreements are in force and (ii) if then serving as
a Class A Director, to offer to resign immediately upon termination of his
employment with the Company.
 
   
     Purchasers of Securities hereunder also will be required to execute and
become a party to the Stockholders Agreement or otherwise be subject to
significant contractual restrictions on the resale of such Securities until an
initial public offering for cash of Common Stock.
    
 
                              CERTAIN TRANSACTIONS
 
     Drs. Rifkin and Kimmel, who are directors, officers and stockholders of the
Company, and Drs. Ancona and Nagel, who are directors of the Company, are
members of the management committee, officers and employees of Baltimore Medical
Group, LLC. The Company and Baltimore Medical Group, LLC have entered into a PSO
Agreement and a Management Services Agreement pursuant to which Baltimore
Medical Group, LLC has accrued fees of $365,000 payable to the Company in
connection with certain professional management services rendered in 1995 and
the first six months of 1996. Dr. Lamm is the Chairman and an employee of
Cumberland Valley Medical Group, LLC, and an employee and director of the
Company. Dr. Rocha is the Chairman and an employee of Carroll Medical Group and
is a Director of the Company.
 
   
     The Company has agreed that it would consult with Med Mutual and follow Med
Mutual's recommendation regarding the provision of medical malpractice coverage
to Equity Physicians and certain of its other Network Physicians. Such decisions
include, but are not limited to, the selection of the underwriter, the form of
the insurance policy and the premium payment provisions. Med Mutual has agreed
to provide medical malpractice coverage to the Company for premiums consistent
with its rates as approved by the Maryland Insurance Administration. In
addition, Med Mutual will consider alternative insurance programs to meet the
Company's special needs and will request the necessary approvals for such
alternative programs from the Maryland Insurance Administration. This agreement
terminates upon the earlier of a change in control of the Company or termination
of the loan guarantee provided by Med Mutual. If the Company breaches this
agreement, the Company may be required to pay Med Mutual $400,000 and Med Mutual
could require the Company to redeem all or a portion of the Series B Preferred
Stock at the price equal to the greater of the fair market value per share or
the sum of the issue price per share and all accumulated and unpaid interest and
dividends.
    
 
   
     Pursuant to Stock Purchase Agreement dated September 4, 1996 (the "Stock
Purchase Agreement"), the Company agreed that it would (i) advise Genesis Health
Ventures, Inc., the Company's Series C Preferred stockholder ("Genesis"), of all
substantive discussions and plans with respect to the delivery of long term
care, pharmacy services, durable medical equipment and home health care services
(the "Services") for the Company, (ii) provide Genesis with all information
needed by Genesis to submit a proposal to provide the Services and (iii) provide
Genesis with an opportunity to provide the Services on commercially reasonable
terms. In addition, the Company has agreed that it will not enter into exclusive
arrangements with third parties that would preclude Genesis from competing to
provide Services to the Company. Genesis and the Company have agreed that
commitments regarding the Services shall not prevent the Company from purchasing
the Services from third parties other than Genesis.
    
 
     Mr. Zetzer, a Director of the Company, is a director of Med Mutual and is a
director of its subsidiary Med-Lantic Management Services, Inc., which is the
sole holder of the Series B Preferred Stock. Ms. Dembiec, a director of the
Company, is Senior Vice President and Chief Financial Officer of Med Mutual.
 
     Mr. Dwyer, who was named Executive Vice President, Chief Financial Officer
and Treasurer of the Company in May 1996, and is a Director of the Company, was
previously a principal of Graham, Hamilton & Dwyer ("GHD"), which provides
financial advisory services to the Company. In 1995, GHD received $100,000 for
such services, and in December 1995, the three principals of GHD each received
warrants to purchase 8,000 shares of Class A Common Stock. At that time, Mr.
Dwyer
 
                                       47
 
<PAGE>
was a principal at GHD and provided investment advice to the Company. The
Company continues to have a relationship with GHD for the provision of financial
advisory services, and GHD may be compensated in an amount up to $340,000 in
1996 in the event that certain financing or acquisition transactions are
consummated. Pursuant to his prior affiliation with GHD, Mr. Dwyer will be
entitled to receive a portion of any such compensation received by GHD.
 
                             PRINCIPAL STOCKHOLDERS
 
   
     The following tables set forth as of October 4, 1996, certain information
with respect to the beneficial ownership of each class of voting stock by: (i)
each person known by the Company to beneficially own more than 5% of each such
class; (ii) each director of the Company of each such class; (iii) each of the
Named Executive Officers of each such class; and (iv) all directors and
executive officers of each such class as a group. The Company believes that the
beneficial owners of the classes of stock listed below, based on information
furnished by such owners, have sole voting and investment power with respect to
such shares, except as noted below. Beneficial ownership is determined in
accordance with the rules of the Securities and Exchange Commission and includes
voting or investment power with respect to the shares. Shares of stock subject
to options currently exercisable or exercisable within 60 days of October 4,
1996 ("Current Options") are deemed outstanding for computing the percentage of
the person holding such options, but are not deemed outstanding for computing
the percentage of any other person.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The Company may offer under this Prospectus one or more of the following
categories of its Securities: (i) shares of its Class B Common Stock, par value
$0.01 per share; (ii) Options to purchase Class B Common Stock; and (iii) any
combination of the foregoing, either individually or as units consisting of one
or more of the types of Securities described in clauses (i) and (ii). The terms
of any specific offering of Securities, including the terms of any units
offered, will be set forth in a Prospectus Supplement relating to such offering.
 
   
     The Company is authorized to issue 20,700,000 shares of Class A Common
Stock, par value $0.01 per share (the "Class A Common Stock"), 10,000,000 shares
of Class B Common Stock, par value $0.01 per share (the "Class B Common Stock")
29,050,000 shares of Class C Common Stock, par value $0.01 per share (the "Class
C Common Stock") (the Class A Common Stock, the Class B Common Stock and the
Class C Common Stock are hereinafter collectively referred to as the "Common
Stock"), 1,000,000 shares of Series A Convertible Preferred Stock, par value
$5.00 per share (the "Series A Preferred Stock"), 355,556 shares of Series B
Convertible Preferred Stock, par value $11.25 per share (the "Series B Preferred
Stock"), 1,071,428 shares of Series C Convertible Preferred Stock, par value
$17.50 per share (the "Series C Preferred Stock") (the Series A Preferred Stock,
the Series B Preferred Stock and the Series C Preferred Stock are hereinafter
collectively referred to as the "Preferred Stock"), and 1,000,000 shares of
other preferred stock having a par value of one cent ($0.01) per share. Shares
of the Preferred Stock are convertible into shares of Class C Common Stock.
    
 
   
     As of October 4, 1996, 800,000 shares of Class A Common Stock are issued
and outstanding and held by three holders of record, 2,504,000 shares of Class B
Common Stock are issued and outstanding and held by fourteen holders of record,
1,000,000 shares of Series A Preferred Stock are issued and outstanding and held
by one holder of record, 355,556 shares of Series B Preferred Stock are issued
and outstanding and held by one holder of record and 428,571 shares of Series C
Preferred Stock are issued and outstanding and held by one holder of record.
    
 
     The following summary description of the capital stock of the Company is
qualified in its entirety by reference to the Company's Articles of Amendment
and Restatement (the "Charter") and Bylaws, copies of which are filed as
exhibits to the Registration Statement of which this Prospectus is a part.
Subject to the rights, privileges and restrictions described below, each issued
and outstanding share of the Common Stock and the Preferred Stock entitles the
holder thereof to one vote on all matters to be voted on by the stockholders of
the Company. There are no preemptive rights or sinking fund provisions with
respect to any of the Company's capital stock.
 
     All shares of the Company's capital stock are subject to significant
restrictions on transfer and will carry a legend to reflect such restrictions.
 
     Except as permitted by the Stockholders Agreement of the Company and the
Charter, the Securities cannot be transferred. The Stockholders Agreement
contemplates that the Company may redeem shares of its stock upon an
"Involuntary Transfer" resulting generally from the insolvency of a stockholder
or upon divorce of an individual stockholder. Voluntary transfers are permitted
only after a stockholder offers its stock, upon the same terms and conditions
contained in the offer it wishes to accept, to all other stockholders on the
terms set out in the Stockholders Agreement. See "Management--Stockholders
Agreement." Individual Stockholders may in certain circumstances make estate
planning transfers for the benefit of themselves or family members on certain
conditions.
 
COMMON STOCK
 
     Except as provided in the Charter, holders of Common Stock are entitled to
one vote per share with respect to all matters submitted to a vote of
stockholders and do not have cumulative voting rights. Subject to preferences
that may be applicable to any outstanding shares of Preferred Stock, holders of
Common Stock are entitled to receive dividends when, as and if declared by the
Board of Directors, out of funds legally available therefor. Upon liquidation,
dissolution or winding up of the Company, holders of Common Stock are entitled
to share ratably in assets available for distribution after payment of all debts
and other liabilities and subject to the prior rights of any holders of any
preferred stock then outstanding.
 
CLASS A COMMON STOCK
 
     The holders of the Class A Common Stock are entitled to elect five of the
18 directors of the Company (each a "Class A Director"). The affirmative vote of
a majority of the stock of Class A Common Stock represented at a meeting at
which a quorum is present is sufficient to approve any matter with respect to
which such holders are entitled to vote; provided, that
 
                                       50
 
<PAGE>
the affirmative vote of a plurality of all votes cast shall be sufficient to
elect a Class A Director. The holders of Class A Common Stock, at any annual
meeting or upon a special meeting called by the holders of not less than 25% of
the shares of Class A Common Stock then outstanding may remove any Class A
Director by the affirmative vote of 80% of all of the votes entitled to be cast
for such Class A Director.
 
CLASS B COMMON STOCK
 
     The holders of the Class B Common Stock are entitled to elect eight of the
18 directors of the Company (each a "Class B Director"). The affirmative vote of
a majority of the stock of Class B Common Stock represented at a meeting at
which a quorum is present is sufficient to approve any matter with respect to
which such holders are entitled to vote; provided, that the affirmative vote of
a plurality of all votes cast shall be sufficient to elect a Class B Director.
The holders of Class B Common Stock, at any annual meeting or upon a special
meeting called by the holders of not less than 25% of the shares of Class B
Common Stock then outstanding may remove any Class B Director by the affirmative
vote of at least a majority of all of the votes entitled to be cast for such
Class B Director. Upon issuance in accordance with the terms of this Prospectus,
the shares of Class B Common Stock being offered hereby will be fully paid and
non-assessable.
 
CLASS C COMMON STOCK
 
     Upon the conversion of all of the Series A Preferred Stock then outstanding
into shares of Class C Common Stock, the holders of such Class C Common Stock
into which such Series A Preferred Stock has been converted, voting as a single
sub-class (the "Series A Subclass"), shall be entitled to elect two of the 18
directors of the Company (each a "Converted Series A Class C Director"). Upon
the conversion of all of the Series B Preferred Stock then outstanding into
shares of Class C Common Stock, the holders of such Class C Common Stock into
which such Series B Preferred Stock has been converted, voting as a single
sub-class ("the Series B Subclass"), shall be entitled to elect two of the 18
directors of the Company (each a "Converted Series B Class C Director"). Upon
the conversion of all of the Series C Preferred Stock then outstanding into
shares of Class C Common Stock, the holders of such Class C Common Stock into
which such Series C Preferred Stock has been converted, voting as a single
sub-class ("the Series C Subclass"), shall, prior to the Company's 1998 annual
meeting of stockholders, be entitled to elect one of the 18 directors of the
Company. After the Company's 1998 annual meeting of stockholders, the Company
shall have 19 directors, and the Series C Subclass shall be entitled to elect
two directors of the Company (each a "Converted Series C Class C Director").
Except with respect to the election of Directors, the affirmative vote of a
majority of the stock of Class C Common Stock represented at a meeting at which
a quorum is present is sufficient to approve any matter with respect to which
such holders are entitled to vote; provided, that the affirmative vote of a
plurality of all votes cast by such Series A Subclass, Series B Subclass, or
Series C Subclass, as the case may be, shall be sufficient to elect a Converted
Series A Class C, Converted Series B Class C Director, or Converted Series C
Class C Director, respectively. The Series A Subclass, the Series B Subclass, or
the Series C Subclass, as the case may be, at any annual meeting or upon a
special meeting called by the holders of not less than 25% of the shares of such
subclass outstanding may remove the Converted Series A Class C, Converted Series
B Class C, or Converted Series C Class C Director, respectively, by the
affirmative vote of 80% of all of the votes entitled to be cast for such
director.
 
     The Charter of the Company includes a provision pursuant to which, upon
completion of a "Qualified" or "Non-Qualified" Public Offering, each share of
the Company's Class A Common Stock, Class B Common Stock, and Class C Common
Stock shall be converted, without any action on the part of the stockholder or
the Company, into an identical share of the Company's Class A Common Stock, and
all special rights granted to the holders of Class A, Class B, and Class C
Common Stock and to all holders of Series A, Series B and Series C Preferred
Stock shall cease and terminate.
 
SERIES A, SERIES B AND SERIES C PREFERRED STOCK
 
     VOTING RIGHTS. Except with respect to the election and removal of
directors, every holder of Series A Preferred Stock, Series B Preferred Stock,
and Series C Preferred Stock shall be entitled to cast that number of votes
equal to the full number of shares of Class C Common Stock into which such
holder's Preferred Stock is then convertible.
 
     SERIES A DIRECTORS. The holders of Series A Preferred Stock voting as a
single class, are entitled to elect two directors (each, a "Series A Director").
The affirmative vote of a majority of the shares of Series A Preferred Stock
represented at a meeting at which a quorum is present is sufficient to approve
any matter with respect to which such holders are entitled to vote; provided,
that the affirmative vote of a plurality of all votes cast shall be sufficient
to elect Series A Directors. The holders of Series A Preferred Stock, at any
annual meeting or upon a special meeting called by the holders of not less than
25% of the shares of Series A Preferred Stock then outstanding, may remove any
Series A Director by the affirmative vote of at least 80% of all of the votes
entitled to be cast for such Series A Director.

<PAGE>
     SERIES B DIRECTORS. The holders of Series B Preferred Stock, voting as a
single class, are entitled to elect two directors (each, a "Series B Director").
The affirmative vote of a majority of the shares of Series B Preferred Stock
represented at a meeting at which a quorum is present is sufficient to approve
any matter with respect to which such holders are entitled to vote; provided,
that the affirmative vote of a plurality of all votes cast shall be sufficient
to elect Series B Directors. The holders of Series B Preferred Stock, at any
annual meeting or upon a special meeting called by the holders of not less than
25% of the shares of Series B Preferred Stock then outstanding, may remove any
Series B Director by the affirmative vote of at least 80% of all of the votes
entitled to be cast for such Series B Director.
 
     SERIES C DIRECTORS. The holders of Series C Preferred Stock, voting as a
single class, are entitled to elect one director until the Company's 1998 annual
meeting of stockholders and thereafter, shall be entitled to elect two directors
(each, a "Series C Director"). The affirmative vote of a majority of the shares
of Series C Preferred Stock represented at a meeting at which a quorum is
present is sufficient to approve any matter with respect to which such holders
are entitled to vote; provided, that the affirmative vote of a plurality of all
votes cast shall be sufficient to elect Series C Directors. The holders of
Series C Preferred Stock, at any annual meeting or upon a special meeting called
by the holders of not less than 25% of the shares of Series C Preferred Stock
then outstanding, may remove any Series C Director by the affirmative vote of at
least 80% of all of the votes entitled to be cast for such Series C Director.
 
     SPECIAL DIRECTOR APPROVAL REQUIREMENT. Pursuant to the Charter, the Company
is generally prohibited from taking certain actions without the separate
affirmative vote of each of the Series A Directors, Series B Directors, and
Series C Directors including (i) the incurrence of certain indebtedness, (ii)
amendments of the Charter or By-Laws that adversely affect the holders of Series
A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock, as the
case may be, or Class C Common Stock, (iii) with respect to the Series A and
Series B Directors, amendments to any of the employment agreements between the
Company and a Management Stockholder, or (iv) with respect to the Series C
Directors, pay any dividend on the Series A or Series B Preferred Stock prior to
September 1, 1998 unless paid in connection with a redemption.
 
   
     SPECIAL PREFERRED STOCKHOLDER APPROVAL REQUIREMENT. Pursuant to the
Charter, the Company is generally prohibited from taking certain actions (each a
"Preferred Stockholder Major Decision") without the separate affirmative vote of
a majority of the shares of Series A Preferred Stock and Series B Preferred
Stock, represented at a meeting, including (i) the adoption of any business plan
of the Company, (ii) the issuance of shares or rights to acquire shares to
employees of the Company which, when aggregated with all other such issuances,
exceeds 10% of the fully diluted shares of capital stock of the Company
(provided; that shares of Class A Common Stock and rights to acquire such shares
issued to the Management Stockholders and other executive employees in amounts
not to exceed 25% of the fully diluted shares of capital stock of the Company as
of December 1, 1995 shall not be counted toward such 10% limitation), (iii) the
issuance of shares of capital stock to any person or entity which has legitimate
business interests that are materially adverse to the holders of Series A
Preferred Stock or the Series B Preferred Stock, as the case may be, (iv) any
sale or other disposition of all or any substantial portion of its assets, or
(v) certain mergers or consolidations of the Company, (vi) any underwritten
public offering other than an offering which is based upon a total market
capitalization of the Company, at the time of such offering, of at least $25
million and from which the Company receives net proceeds of not less than $15
million. Additionally, the separate vote of the holders of Series A Preferred
Stock is required for any optional redemption of the Series B Preferred Stock,
unless the Company has previously redeemed the Series A Preferred Stock. The
Charter provides that notwithstanding the failure to obtain the approval of such
Preferred Stockholder Major Decisions, the Company may nonetheless take such
actions; provided that the Company provide advance written notice of the action
and subject to the right of the holders of each Series of Preferred Stock to
require the Company to redeem all of each such Series in accordance with the
terms of the Charter.
    
 
     REDEMPTION. The Series A Preferred Stock, the Series B Preferred Stock and
the Series C Preferred Stock must be redeemed by the Company (unless such right
is waived in writing by the holder of Preferred Stock), or may be redeemed at
the request of the holders of Preferred Stock, in a number of different
circumstances, including: (i) sale of all or substantially all of the assets of
the Company; (ii) the filing by the Company of a voluntary or involuntary

     CONVERSION. All, but not less than all, of the shares of the Series A and
Series B Preferred Stock are convertible, one share for one share (subject to
increase if the Company issues shares at a dilutive price), into shares of Class
C Common Stock at the option of holders of the Series A and Series B Preferred
Stock at any time prior to 5:00 p.m. (EST) on February 24, 2000. However,
holders of the Series A Preferred Stock who have not made full payment in cash
to the Company for the shares of Series A Preferred Stock may not convert their
shares. All, but not less than all, of the shares of Series C Preferred Stock
are convertible, one share for one share (subject to increase if the Company
issues shares at a dilutive price), into shares of Class C Common Stock at the
option of holders of the Series C Preferred Stock at any time. Shares of
Preferred Stock will automatically be converted (unless redeemed), one share for
one share (subject to dilution adjustments), into shares of Class C Common Stock
upon the occurrence of a combination, consolidation or merger transaction
involving the Company in which the Company is not the survivor, the sale,
exchange or other disposition of all, or substantially all, of the Company's
assets, and upon the consummation of any public offering of securities of the
Company.
 
     The special voting and approval rights of the holders of the Preferred
Stock and their rights to require the redemption of the Preferred Stock or to
convert such Preferred Stock into Class C Common Stock may prevent the Company
from consummating one or more transactions, including equity and debt financings
that could be beneficial to the Company's stockholders.
 
   
     DIVIDENDS. Prior to April 1, 2000, cash dividends at the rate of $0.325 per
share per annum accrue on the Series A Preferred Stock. Such dividends are
cumulative and will accrue, whether or not earned or declared or payment is
legally available, from and after the 24th day of February, 1995 and bear
interest on accrued but unpaid amounts at the rate of 6.5% per annum, compounded
quarterly. Such accrued dividends and interest are payable only upon the
liquidation of the Company or the redemption or conversion of the Series A
Preferred Stock and if not paid prior to April 1, 2000, the amount of such
accrued but unpaid dividends and interest payments will become an unsecured
obligation of the Company. On or after April 1, 2000, holders of the Series A
Preferred Stock are entitled to receive, when and as declared by the directors
of the Company and when legally available, cash dividends at the per annum rate
of 100 basis points over the Wall Street Journal Prime Rate as of the last
business day prior to April 1, 2000 based on the original issue price of the
Series A Preferred Stock. So long as any shares of Series A Preferred Stock are
issued and outstanding, no dividends may be declared and no other distribution
may be made, with certain exceptions, with respect to any other class or series
of stock or equity interest of the Company without the consent of each director
elected by the holders of the Series A Preferred Stock.
    
 
   
     Prior to April 1, 2000, cash dividends at the rate of $1.097 per share per
annum accrue on the Series B Preferred Stock. Such dividends are cumulative and
will accrue, whether or not earned or declared or payment is legally available,
from and after the first day of December, 1995 and bear interest on accrued but
unpaid amounts at the rate of 9.75% per annum, compounded quarterly. Such
dividends and interest are payable only after all dividends and interest accrued
on or with respect to the Series A Preferred Stock have been paid and only upon
the liquidation of the Company or the redemption or conversion of the Series B
Preferred Stock and if not paid prior to April 1, 2000, the amount of such
accrued but unpaid dividends and interest payments will become an unsecured
obligation of the Company. On and after April 1, 2000, holders of the Series B
Preferred Stock are entitled to receive, when and as declared by the directors
of the Company and when legally available, cash dividends at the per annum rate
of 100 basis points over the Wall Street Journal Prime Rate as of the last
business day prior to April 1, 2000 based upon the original issue price of the
Series B Preferred Stock.
    
 
     Cash dividends at the rate of $1.40 per share per annum accrue on the
issued and outstanding Series C Preferred Stock and cash dividends at the rate
of $1.60 per share per annum shall accrue on shares to be issued pursuant to the
Option Agreement with Genesis. Such dividends are cumulative and will accrue,
whether or not earned or declared or payment is legally available, from and
after September 4, 1996 and bear interest on accrued but unpaid amounts at the
rate of 8.00% per annum. Such dividends and interest are payable only after all
dividends and interest accrued on or with respect to the Series A and Series B
Preferred Stock have been paid and only upon the liquidation of the Company or
the redemption or conversion of the Series C Preferred Stock and if not paid,
the amount of such accrued but unpaid dividends and interest payments will
become an unsecured obligation of the Company, bearing interest at the per annum
rate of 100 basis points over the Wall Street Journal Prime Rate as of the last
business day prior to such liquidation, redemption or conversion. All accrued
dividends and unpaid interest on the Series C Preferred Stock shall be canceled
and no longer be payable in the event the Company consummates a Qualified Public
Offering on or before August 30, 1998 at a price per share of not less than the
weighted average price paid or to be paid by the holders of Series C Preferred
Stock for all shares of Series C Preferred Stock then outstanding or subject to
the Option, plus all accrued but unpaid dividends and interest thereon. So long
as any shares of Series C Preferred Stock remain outstanding, no dividends shall
be declared or paid upon, nor shall any dividend or other distribution be made
with respect to, any shares or any other class or series of stock or equity
interest of the Company other
 
                                       53
 
<PAGE>
than the Series A Preferred Stock or Series B Preferred Stock without the
consent of the Series C Preferred Director or Directors.
 
     The Company may not issue any shares of capital stock which are senior in
dividend and/or liquidation rights to the Preferred Stock, and the Preferred
Stockholders have certain anti-dilution rights with respect to most issuances of
capital stock by the Company which are junior to the Preferred Stock and which
are issued for a share price less than the original per share price of the
Preferred Stock.
 
     LIQUIDATION RIGHTS. Upon liquidation of the Company, holders of the Series
A Preferred Stock, if any, are entitled to receive a liquidating distribution
equal to the greater of (i) the sum of the fair market value per share of the
Series A Preferred Stock plus all accrued but unpaid dividends thereon, or (ii)
the sum of the original purchase price per share of the Series A Preferred Stock
plus all accrued but unpaid dividends thereon. After payment of such
preferential amount to the holders of the Series A Preferred Stock, holders of
the Series B Preferred Stock, if any, are entitled to receive a liquidating
distribution equal to the greater of (i) the sum of the fair market value per
share of the Series B Preferred Stock plus all accrued but unpaid dividends
thereon, or (ii) the sum of the original purchase price per share of the
Preferred Stock plus all accrued but unpaid dividends thereon. After payment of
such preferential amount to the holders of the Series A and Series B Preferred
Stock, holders of the Series C Preferred Stock, if any, are entitled to receive
a liquidating distribution in the amount of $17.50 per share of Series C
Preferred Stock issued pursuant to the Stock Purchase Agreement which is then
outstanding and $20.00 per share of Series C Preferred Stock issued pursuant to
the Option Agreement which is then outstanding, plus all accrued but unpaid
dividends and interest thereon. After payment of the preferential liquidation
amounts to the holders of Series A, Series B and Series C Preferred Stock, each
share of Common Stock is entitled to share ratably with all other shares of
Common Stock in the remaining net assets of the Company upon liquidation.
 
PERMITTED REDEMPTIONS
 
     The Charter provides that the Company may effect the following redemptions
without the consent or approval of any of the Series A Preferred Directors, the
Series B Preferred Directors, the Series C Preferred Directors, the holders of
Series A Preferred Stock, the holders of Series B Preferred Stock and the
holders of Series C Preferred Stock:
 
           (i) upon the payment in full of all accumulated and unpaid accrued

               employment agreement, except that such redemptions may be made
               without payment of accrued dividends and interest on outstanding
               shares of Series C Preferred Stock if the Company completes a
               Qualified Public Offering of its securities prior to August 30,
               1998;
 
           (ii) redemptions of shares of Class A Common Stock owned by any
                employee (other than a Management Stockholder) when and as

                agreement with such employee;
 
           (iii) redemptions of Class B Common Stock issued by the Company to

           (iv) redemptions under any other circumstances expressly contemplated
                by the Stockholders Agreement, including any amendments thereto

           (vi) certain redemptions of Series B Preferred Stock in accordance
                with the Charter; provided, that no such redemption shall be
                permitted or effected unless and until the Company has elected
                to redeem all of the issued and outstanding Series A Preferred
                Stock and the price applicable to such redemption shall have
                been paid in full or adequate provision made therefor.
 
          (vii) certain redemptions of Series C Preferred Stock in accordance
                with the Charter; provided, that no such redemption shall be

                B Preferred Stock and the price applicable to such redemption
                shall have been paid in full or adequate provision made

DESCRIPTION OF OPTIONS
 
   
     GENERAL.
    
 
     The Company may issue Options for the purchase of Class B Common Stock.
Options may be issued independently or together with any other Securities
covered by the Registration Statement and offered by this Prospectus and any
accompanying Prospectus Supplement and may be attached to or separate from such
other Securities. Each series of Options will be issued under a separate
agreement (each, an "Option Agreement") to be entered into between the Company
and the holder of such Options, all as set forth in the Prospectus Supplement
relating to the particular issue of offered Options.
 
     The applicable Prospectus Supplement will describe the terms of such
Options, including the following where applicable: (i) the offering price; (ii)
the aggregate number of shares purchasable upon exercise of such Options; (iii)
the designation and terms of the Securities with which such Options are being
offered, if any, and the number of such Options being offered with each such
Security; (iv) if applicable, the date on and after which such Options and the
related Securities will be transferable separately; (v) the number of shares of
Class B Common Stock purchasable upon exercise of each such Option and the price
at which such number of shares of Class B Common Stock may be purchased upon
such exercise; (vi) the date on which the right to exercise such Options shall
commence and the expiration date on which such right shall expire; (vii) certain
federal income tax consequences; and (viii) any other material terms of such
Options.
 
     Prior to the exercise of any Option to purchase Class B Common Stock,
holders of such Options will not have any rights of holders of the Class B
Common Stock purchasable upon such exercise, including the right to receive
payments of dividends, if any, on the Class B Common Stock purchasable upon such
exercise or to exercise any applicable right to vote.
 
   
     EXERCISE OF OPTIONS.
    
 
     Each Option will entitle the holder thereof to purchase such number of
shares of Class B Common Stock, at such exercise price as shall in each case be
set forth in, or calculable from, the Prospectus Supplement relating to the
offered Options. After the close of business on the expiration date (or such
later date to which such Expiration Date may be extended by the Company),
unexercised Options will become void.
 
     Options may be exercised by delivering to the Company payment, as provided
in the applicable Prospectus Supplement, of the amount required to purchase the
Class B Common Stock purchasable upon such exercise together with certain
information set forth on the reverse side of the Option Certificate. Upon
receipt of such payment and the definitive Option Certificates properly
completed and duly executed, the Company will, as soon as practicable, issue and
deliver the Class B Common Stock purchasable upon such exercise. If fewer than
all of the Options represented by such Option Certificate are exercised, a new
Option Certificate will be issued for the remaining amount of Options.
 
   
     AMENDMENTS AND SUPPLEMENTS TO OPTION AGREEMENTS.
    
 
     Each Option Agreement may be amended or supplemented without the consent of
the holders of the Options issued thereunder to effect changes that are not
inconsistent with the provisions of the Options and that do not adversely affect
the interests of the holders of the Options.
 
   
     OPTION ADJUSTMENTS.
    
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
exercise price of, and the number of shares of Class B Common Stock covered by,
an Option are subject to adjustment in certain events, including: (i) the
issuance of Common Stock as a dividend or distribution on the Common Stock; (ii)
subdivisions and combinations of the Common Stock; and (iii) the distribution to
all holders of Common Stock of evidences of indebtedness or assets of the
Company (excluding certain cash dividends and distributions described below).
The terms of any such adjustment will be specified in the related Prospectus
Supplement for such Options.
 
   
     NO RIGHTS AS STOCKHOLDERS.
    
 
     Holders of Options will not be entitled by virtue of being such holders, to
vote, to consent, to receive dividends, to receive notice as stockholders with
respect to any meeting of stockholders for the election of directors of the
Company of any other matter, or to exercise any rights whatsoever as
stockholders of the Company.
 
                                       55
 
<PAGE>
   
     EXISTING SECURITIES HOLDERS.
    
 
     The Company may issue, as a dividend at no cost, such Options to holders of
record of the Company's Securities or any class thereof on the applicable record
date. If Options are so issued to existing holders of Securities, the applicable
Prospectus Supplement will describe, in addition to the terms of the Options and
the Securities issuable upon exercise thereof, the provisions, if any, for a
holder of such Options who validly exercises all Options issued to such holder
to subscribe for unsubscribed Securities (issuable pursuant to unexercised
Securities Options issued to other holders) to the extent such Securities
Options have not been exercised.
 
                              PLAN OF DISTRIBUTION
 
   
     Securities may be issued from time to time in connection with the
affiliation of medical practices with the Company. The Company may sell
Securities (a) directly to one or more purchasers, or (b) through agents. A
Prospectus Supplement will set forth the specific terms of the offering of the
Securities offered thereby, including, without limitation, to the extent
applicable (1) in the case of Options, the Class B Common Stock for which each
such Option is exercisable, and the exercise price, duration, detachability,
restrictions and call provisions of each such Option; and (2) in the case of any
offering of Securities, to the extent applicable, the offering price or prices,
certain Federal income tax consequences and the agents or dealers, if any,
participating in the offering and sale of the Securities.
    
 
   
     It is anticipated that the affiliations of the medical practices will
involve (a) in the case of the acquisition of medical practices, the receipt by
the Company primarily of enumerated tangible assets of such practices and
related contracts and leases, and (b) in the case of contractual arrangements,
the receipt of the contractual consideration specified in the relevant contract.
The Company will not receive cash proceeds from the issuance of the Securities.
    
 
   
     The terms of an affiliation are determined by negotiations between the
Company's representatives and physicians. Factors taken into account in such
transactions include the established size, quality and reputation of the
practice and the market value of the Company's estimate of the Class B Common
Stock. It is anticipated that shares of Class B Common Stock issued in any such
affiliation will, in most cases, be valued at a price reasonably related to the
current market value of the Class B Common Stock, either at the time that the
terms of the affiliation agreement are tentatively agreed upon, or at or about
the time of closing, or during the period or periods prior to delivery of the
shares.
    
 
   
     It is not expected that underwriting discounts or commissions will be paid
by the Company except that finder's fees may be paid to persons from time to
time in connection with specific acquisitions. The Company may issue all or a
portion of any offering of its Securities through agents or directly to other
purchasers. The related Prospectus Supplement for each offering of Securities
will set forth the name of any agents involved in the issuance of such
Securities and any applicable fee, commission or indemnification agreement with
any such party.
    
 
   
     The Securities issued hereunder will be new issue of securities with no
established trading market. The Company does not currently intend to apply for
the listing of any Securities on any national securities exchange. No assurance
can be given as to the liquidity of the trading market for any such Securities.
The Securities offered hereby will be subject to certain contractual
restrictions on resale, including the Stockholders Agreement. See "Description
of Capital Stock", "Risk Factor--Voting Limitations; Restrictions on Resale of
Securities" and "--Absence of Public Market" and "--Penny Stock Rules."
    
 
                                 LEGAL MATTERS
 
     The validity of the Securities offered hereby will be passed upon for the
Company by Venable, Baetjer and Howard, LLP, Baltimore, Maryland.

BOARD OF DIRECTORS AND STOCKHOLDERS
DOCTORS HEALTH SYSTEM, INC.
 
   
     We have audited the accompanying consolidated balance sheets of Doctors
Health System, Inc. (a Maryland corporation, formerly Baltimore Medical Group,
P.A.), as of June 30, 1996, 1995 and 1994, and the related consolidated
statements of operations, stockholders' equity, and cash flows for the years
then ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 audits 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 Doctors Health
System, Inc. as of June 30, 1996, 1995 and 1994, and the consolidated results of
its operations and its cash flows for the years then ended, in conformity with
generally accepted accounting principles.
    
 
   
     We have also audited Schedule II--Valuation and Qualifying Accounts for the
years ended June 30, 1996, 1995 and 1994. In our opinion, this schedule presents
fairly, in all material respects, the information required to be set forth
therein.

        in May 1996)
 
     A summary of the significant accounting policies consistently applied in
the preparation of the accompanying consolidated financial statements follows.
 
     BASIS OF PRESENTATION/PRINCIPLES OF CONSOLIDATION
 
   
     The consolidated financial statements have been prepared on the accrual
basis of accounting and include the accounts of the Company and its subsidiaries
and affiliates. The Company has adopted a June 30th year end. The agreements
entered into as part of the acquisitions convey to the Company perpetual,
unilateral control over the assets and operation of the various Core Medical
Groups (CMGs). The Company's PSO Agreements have a 30 year term with unlimited
10 year renewals. Perpetual control by the Company is evidenced by (i) the
Company's exclusive right to manage each CMG's business (other than matters
involving clinical judgment and certain health care services), (ii) its control
over the admission and withdrawal of the members of the CMGs, (iii) its
responsibility for all liabilities and obligations of the CMGs, (iv) its
exclusive right to contract for the CMGs, (v) the length of the original term of
the PSO Agreements, (vi) the Company's ownership of the assets used by the CMGs,
(vii) a high degree of commonality between the shareholders, officers and
directors of the Company and the CMGs, (viii) the continuing investment of
capital by the Company, (ix) the employment of and the incurrence of expenses
for the non-physician personnel and (x) the nature of the services provided to
the CMGs by the Company. Pursuant to the PSO Agreements, the Company provides
the CMGs with capital, management expertise, sophisticated information systems
and managed care contracts. Notwithstanding the lack of any ownership of the
equity interests in such entities, consolidation of the CMGs is necessary to
present fairly the financial position and results of operations of the Company
because there exists a parent-subsidiary relationship by means other than record
ownership of equity interests. All intercompany accounts and transactions have
been eliminated in the consolidation.

NOTE 1--BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--CONTINUED
     REVENUES AND MEDICAL SERVICE EXPENSE RECOGNITION
 
   
     Net physician revenue of the Company consists primarily of fees for medical
services provided by the physicians under fee-for-service type arrangements or
under capitated gatekeeper contracts with various managed care payors including
health maintenance organizations (HMOs). Fee-for-service revenues are generated
from direct patient and third-party billings and are recognized when services
are performed. These revenues are recorded net of adjustments and allowances
resulting from the difference between the customary and usual rates for
physician services and amounts reimbursable by govenment-sponsored healthcare
programs (principally, the Medicare and Medicaid programs), commercial insurance
carriers and other health insurance programs. During 1996, the Company estimates
that approximately 42% of net physician revenues were received under
government-sponsored healthcare programs and 21% were received under various
contracts with Blue Shield. The captitated gatekeeper revenue is prepaid monthly
based on the number of Enrollees and recognized as net physician revenue during
the month when services are provided (normally the same month as receipt).
    
 
   
     In addition, the Company has three global capitated contracts with HMOs
whereby it receives monthly capitation fees based on the number of Enrollees
electing any one of the Company's primary care physicians. The captitation
revenue under these contracts is prepaid monthly based on the number of
Enrollees and recognized as global capitation revenue during the month of
receipt.
    
 
   
     The Company's commercial capitation contract also includes a provision to
share in the risk for hospitalization, whereby the Company can earn additional
incentive revenue or incur medical service expenses based upon the Enrollees'
utilization of hospital services. Estimated shared-risk amounts receivable or
payable from the HMO are recorded based upon hospital utilization and associated
costs incurred by assigned HMO Enrollees, compared to budgeted costs.
Differences between actual contract settlements and estimated receivables or
payables relating to the risk-sharing arrangement are recorded in the year of
settlement. Included in accrued medical services as of June 30, 1996 is
approximately $68,000 of estimated amounts due to the HMO under this
arrangement. Also, as of June 30, 1996, the Company has included in accrued
medical services a provision of approximately $77,000 which represents an
estimate of the loss to be incurred over the remaining term of the commercial
capitation contract. Under the Company's two Medicare full risk capitation
contracts, the Company has assumed responsibility for managing and paying for
substantially all of the medical care for the respective payors' Enrollees.
    
 
   
     The Company is responsible for some or all of the medical services provided
by its physicians and other providers to which it refers its patients who are
covered under global capitated contracts. The cost of medical services is
recognized in the period in which it is provided and includes an estimate of the
cost of services which have been incurred but not yet reported. The estimate for
accrued medical services is based on projections of costs using historical
studies of claims paid. Estimates are continually monitored and reviewed and, as
settlements are made or estimates are adjusted, differences are reflected in
current operations. As of June 30, 1996, approximately $400,000 was recorded as
accrued medical services for incurred but not reported services.
    
 
   
     The Company purchases reinsurance which limits the amount of risk it
ultimately bears by providing reimbursement payments once medical services
provided to an individual Enrollee exceed an agreed-upon amount. Estimates of
reinsurance recoveries as of June 30, 1996 under this arrangement were
approximately $23,000.
    
 
     CASH AND CASH EQUIVALENTS
 
     The Company considers all highly liquid investments with original
maturities of three months or less when purchased to be cash equivalents.
 
     ACCOUNTS RECEIVABLE
 
   
     Accounts receivable principally represent receivables from third party
payors for patient medical services provided by physician groups, including
receivables assigned by such physician groups pursuant to PSO Agreements. Such
amounts are recorded net of contractual allowances and estimated bad debts.
    
 
   
     As of June 30, 1996, approximately $1,200,000 of the Company's accounts
receivable represented amounts due from the Medicare and Medicaid programs in
respect of which the Company has legal rights to the proceeds.

NOTE 1--BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--CONTINUED
     MEDICAL SUPPLIES
 
     The Company expenses the cost of routine medical and laboratory supplies
when purchased.
 
     PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. Depreciation and amortization
are provided for in amounts sufficient to relate the cost of depreciable assets
to operations over their estimated service lives, ranging from three to ten
years. Leasehold improvements are amortized over the lives of the respective
leases or the service lives of the improvements, whichever is shorter. Leased
property under capital leases is amortized over the lives of the respective
leases or over the service lives of the assets, whichever is shorter. The
straight-line method of depreciation is followed for substantially all assets
for financial reporting purposes and accelerated methods are used for tax
purposes.
 
     DEFERRED CHARGES AND INTANGIBLE ASSETS
 
     Deferred charges include (i) deferred loan acquisition costs, (ii) deferred
physician employment contract costs and (iii) organization costs. These costs
are being amortized to operations using the straight-line basis over the term of
the Series B Preferred shareholder's loan guarantee (25 months), the term of the
employment agreements (generally 10 years) and five years for organization
costs.
 
   
     Intangible assets consist of the excess of the purchase price paid over the
fair value of net assets acquired. The Company's policy is to amortize
intangibles over a 10 to 40 year period. The intangibles acquired during 1995
and 1996 are being amortized using the straight-line method over 20 years.
Management does not believe that any current factors indicate an impairment of
intangibles acquired. Management will review the carrying value at each future
reporting period to determine if any impairment has occurred.
    
 
     INCOME TAXES
 
     The Company is a corporation subject to federal and state income taxes. The
Company's year-end for tax reporting purposes is December 31. Deferred income
taxes result from the future tax consequences associated with temporary
differences between the amount of assets and liabilities recorded for financial
accounting and income tax purposes. Currently, these temporary differences
relate primarily to net operating loss carryforwards and depreciation
differences. Future use of the net operating loss carryforwards by the Company
may be limited due to certain changes in control as provided for in the Internal
Revenue Code.
 
     Certain of the consolidated subsidiaries are limited liability companies
(LLCs), which are treated as partnerships for federal and state income tax
purposes. The Company's compensation plans for physicians result in these
entities reporting little or no taxable income. To the extent that additional
amounts are paid to member physicians to cover income tax expense incurred, they
will be reported as distributions. These amounts are not deductible for federal
or state income tax purposes.
 
     USE OF ESTIMATES
 
     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.
 
     NEWLY ISSUED ACCOUNTING STANDARDS
 
   
     In March 1995, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR
LONG-LIVED ASSETS TO BE DISPOSED OF, which requires that long-lived assets and
certain identifiable intangibles held and used by the Company be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. If this review indicates
that the carrying amount of the long-lived assets may not be recoverable, the
carrying value of those assets would be reduced to fair value. The Company will
implement the standard when it becomes effective (effective date is for fiscal
years beginning after December

15, 1995), and does not believe implementation of the standard would have a
material impact on the Company's financial statements.
    
 
   
     In October 1995, FASB issued SFAS No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION, which requires entities to measure compensation costs related to
awards of stock-based compensation using either the fair value method or the
intrinsic value method. Under the fair value method, compensation expense is
measured at the grant date based on the fair value of the award. Under the
intrinsic value method, compensation expense is equal to the excess, if any, of
the quoted market price of the stock at the grant date over the amount the
employee must pay to acquire the stock. Entities electing to measure
compensation costs using the intrinsic value method must make pro forma
disclosures for fiscal years beginning after December 15, 1995, of net income
and earnings per share as if the fair value method had been applied. The Company
has elected to account for stock-based compensation programs using the intrinsic
value method and, therefore, the standard will have no effect on the
consolidated financial statements.
    
 
NOTE 2--ACQUISITIONS
 
   
     During the years ended June 30, 1995 and 1996, the Company acquired certain
operating assets and assumed certain operating liabilities of physician groups
located in Maryland. The acquisitions have been accounted for by the purchase
method of accounting, and accordingly, the purchase price has been allocated to
the assets acquired based on the estimated fair values at the dates of
acquisition. Accounts receivable acquired were valued at their net realizable
values based upon analyses made by the Company. The estimated fair value of
assets acquired, liabilities assumed and consideration paid are summarized as
follows:

     The operating results of acquired physicians during the year ended June 30,
1995 have been included in operations since their respective dates of
acquisition. Had the acquisition occurred as of July 1, 1994, the effect on the
Company's revenues, net loss and loss per share, for the year ended June 30,
1995, would not have been material. Had the acquisitions completed during the
year ended June 30, 1996 occurred as of July 1, 1995, the Company's net revenues
for the year ended June 30, 1996 would have increased. Unaudited pro-forma
results for the year ended June 30, 1996 would have been: net revenues of
$14,043,000 and the net loss for the period would have been $6,629,058 or
$(2.34) per share.
    
 
   
     Generally the contracts with individual physicians provide for a nine month
period during which the parties may cancel the contract. If this option is
exercised, the Company and the physician would be restored to their respective
positions before the acquisition. Expenses and fees incurred for professional
services in connection with acquisitions are considered part of the acquisition
cost and are capitalized in the financial statements as deferred acquisition
costs. During 1995 and 1996, the Company has capitalized costs of approximately
$22,000 and $43,000, respectively, as part of the acquisitions. In the event
that a physician exercises his option to leave or retire, the Company charges
any unamortized deferred costs associated with the acquisition to operations in
the period when notice of withdrawal is received. At June 30, 1996, 25
physicians have remaining reacquisition options for periods expiring through
February 1997. Total assets at June 30, 1996 and revenues for

the year ended June 30, 1996 attributable to physicians with reacquisition
rights amounted to $1,349,499 and $2,574,826, respectively. Subsequent to June
30, 1996, reacquisition rights for 8 of the 25 physicians, or $277,533 in total
assets and $1,062,921 in revenues, have expired without recission. During 1995,
one physician canceled his interest in the Company. This cancellation did not
require the disbursement of cash or other assets since the transaction was never
funded.
    
 
   
NOTE 3--OPERATING MATTERS AND LIQUIDITY
    
 
   
     It is reasonably possible that future near term events may result in
changes in estimates that would be material to the financial statements.
    
 
   
     OPERATING LOSSES; LIQUIDITY
    
 
   
     The foregoing business description discusses the current nature of the
Company's operations. Until there are an adequate number of capitated patients
in the Company's global capitated contracts, the Company expects to incur
operating losses and experience negative operating cash flows. The Company
believes that its cash on hand, the $2,500,000 to be received on or before
December 27, 1996 from the holder of its Series C Preferred Stock, and the
amount of remaining availability under the NationsBank Credit Facility described
in Note 7, will be sufficient to meet the Company's immediate working capital
needs. However, in the event that the Company either has not attracted an
adequate number of capitated patients in global capitated contracts in order to
offset operating expenses, or has not secured some substantial portion of the
additional capital outlined in Note 19 or other capital, the Company's
operations and liquidity would be adversely affected.
    
 
     INVESTMENT IN TANGIBLE ASSETS AND INFRASTRUCTURE
 
   
     For the year ended June 30, 1996, the majority of the Company's revenue
resulted from the delivery of health care services on a fee-for-service basis
and gatekeeper capitated income. In order to achieve its business objectives and
to recover amounts that have been invested in tangible assets, the formation of
the infrastructure and development of the business, it is necessary for
management to renew its current global capitated contracts and increase the
number of enrolled lives. In the event these contracts are not renewed and
expanded to other geographical areas in the Baltimore and Washington
metropolitan area and surrounding regions or the Company does not increase the
number of enrolled lives, the Company would most likely be unable to generate
sufficient revenues to cover its ordinary and necessary expenses or would not
require all of the assets owned or leased.
    
 
NOTE 4--NOTE RECEIVABLE
 
   
     The note receivable results from an advance to a medical practice which the
Company has a binding letter of intent to acquire for the approximate value of a
portion of the practice's net realizable accounts receivable. The note was
issued to secure the Company's right to repayment of the face amount of the note
in the event that the Company does not complete the acquisition of the medical
practice. Interest on the note is calculated based on the prime rate (8.25% as
of June 30, 1996). The note matures on March 1, 1997. Upon consummation of the
purchase of the physician's practice by the Company the note receivable will be
cancelled and the advance will be treated as part of the consideration paid,
accordingly, this note has been reflected as a non-current asset.

NOTE 6--NOTES PAYABLE
 
   
     The Company had an agreement with a commercial bank that provided for a
line of credit for $150,000 that matured on February 29, 1996. In February 1996,
the Company and the bank agreed to revise the terms that extended the maturity
to February 28, 1997, reduced the borrowing limit to $100,000 and reduced the
interest rate to the bank's prime rate. Prior to the revision, interest accrued
on advances at the bank's prime rate plus 1 1/2% per annum (10.2% effective rate
at June 30, 1996) and is payable monthly. The line is collateralized by
specified accounts receivable and certain equipment. Advances under the line
were $100,674, $64,248 and $50,000 at June 30, 1994, 1995 and 1996,
respectively. The Company is required to be out of the line for 90 days
annually.
    
 
   
     In connection with the acquisitions of individual medical practice assets
and other transactions, the Company is obligated on short-term notes payable to
physicians and others aggregating approximately $303,915 at June 30, 1996.

     In December 1995, the Company entered into a loan agreement with
NationsBank, N.A. (the NationsBank Credit Facility), under which the Company may
request advances up to a maximum of $4 million. Interest on advances is payable
monthly and is calculated based on the bank's prime rate, unless the Company
designates a portion of the advances to be subject to the Eurodollar rate plus
 .75% (effective rate of 6.2% at June 30, 1996). All advances are due at December
31, 1997. The Company has outstanding advances under this agreement of
$3,400,000 at June 30, 1996. The bank has the right to offset the Company's
demand deposit accounts with the bank against any past due amounts.
    
 
   
     The NationsBank Credit Facility is guaranteed by the holder of the
Company's Series B Preferred Stock. The guarantee is collateralized by a
security interest in all receivables and the PSO Agreements between the Company
and Baltimore Medical. The guarantee agreement also provides for certain
restrictions on the Company, including limitations on incurring additional debt
and reduction of amounts due from the Series A Preferred Stockholder. Upon
redemption of the Series B

Preferred Stock in connection with issuance of "junior stock" to a holder whose
interests are deemed adverse to the guarantor, then the Company is required to
obtain a release of the guarantee. As consideration for the guarantee, the
Company issued a warrant valued at $370,000 for the purchase of its common stock
(see note 13).
    
 
   
     The Company is obligated on notes payable to various physicians, who are
members of either Baltimore Medical, Carroll Medical or Cumberland Valley
Medical, in connection with the original purchase of the accounts receivable
from the physicians' former practices by Medical Holdings Limited Partnership
(MHLP) or other subsidiaries. The notes bear interest at rates ranging from
9.75% to 10% and the notes mature at the earlier of seven years from the date of
closing or any of the following events: (i) termination of the respective
Professional Services Employment Agreements, (ii) a liquidating distribution to
the stockholders of the Company, (iii) combination, consolidation or merger
where the Company is not the survivor, (iv) disposal of substantially all of the
Company' assets, or (v) a public offering with a certain cash issuance amount to
the Company. The notes may be reduced or adjusted based on receivable
collections and may be prepaid without penalty. The Company does not expect to
conclude an underwritten public offering of the Company's securities for cash
before June 30, 1997. Accordingly, these notes have been classified as long-term
obligations.
    
 
NOTE 8--CAPITAL LEASE OBLIGATIONS
 
   
     The Company has entered into capital leases for computer equipment and
software and for laboratory equipment. These leases are noncancelable and have
terms that expire at various dates through 2000. Assets under capital leases as

NOTE 9--COMMITMENTS AND CONTINGENCIES
 
     MALPRACTICE COVERAGE
 
     The Company has purchased a claims-made policy with coverage limits of $1
million per medical professional per incident and $3 million annual aggregate
per medical professional. This policy expires on January 1, 1997 and it is
management's intention to obtain renewal coverage. The Company has obtained
retroactive coverage for physicians that were not

previously covered by the current carrier (prior to the physician's affiliation
with the Company). The financial statements include an estimate to cover future
costs that may arise from claims that have been incurred but not reported.
Management believes that losses and costs related to unknown incidents not
provided for, if any, would not be material to the financial position, liquidity
or results of operations of the Company.
 
   
     Pursuant to an agreement dated December 1, 1995, the prior written approval
of the Series B Preferred Stockholder is required in connection with decisions
regarding medical malpractice coverage for the Company, participating physicians
and affiliated entities. Such decisions include, but are not limited to, the
selection of the underwriter, the form of the insurance policy and the premium
payment provisions. The Company must make certain payments to the Series B
Preferred Stockholder if the required approval is not obtained: the Series B
Preferred Stockholder could require the Company to pay it $400,000 and to redeem
all or a portion of the Series B Preferred Stock at the price equal to the
greater of the fair market value per share or the sum of the issue price per
share and all accumulated and unpaid interest and dividends. The Series B
Preferred Stockholder agrees to provide medical malpractice coverage to the
Company for premiums consistent with its rates as approved by the Maryland
Insurance Administration. In addition, the Series B Preferred Stockholder will
consider alternative insurance programs to meet the Company's special needs and
will request the necessary approvals for such alternative programs from the
Maryland Insurance Administration. This agreement terminates upon the earlier of
a change in control of the Company or termination of the loan guarantee provided
by the Series B Preferred Stockholder.
    
 
   
     EMPLOYEE BENEFIT PLANS
    
 
   
     Effective January 1, 1996, the Company adopted a 401(k) Plan (the Plan)
covering all its employees. Subject to certain limitations, participants may
elect to defer a portion of their compensation as contributions to the Plan. The
Company will make matching contributions of 50% of each participant's
contribution up to six percent of the participant's salary. Participants vest in
the Company's contributions at the rate of 20% per year beginning in fiscal
1997. Contributions of $160,000 were expensed in fiscal 1996.
    
 
   
     Effective February 1, 1996, the Company adopted a Flexible Benefits Plan
covering all full-time employees. Subject to certain limitations, the Company
may make "non-elective contributions" on behalf of employees and employees may
elect to defer a portion of their compensation as "flexible pay contributions"
to pay for certain covered expenses.
    
 
     OPERATING LEASES
 
   
     The Company conducts its operations at leased facilities and uses leased
office equipment under noncancelable operating leases. Certain of the leased
facilities are owned by physicians who have membership interests in affiliates.
The operating leases have initial terms that expire at various times through
2008 and, generally, provide for renewal for various periods at stipulated
rates. Some of the operating leases provide that the Company pay taxes,
maintenance, insurance and other occupancy costs applicable to leased premises.
Total rent expense for all operating leases approximated $134,850, $207,110 and
450,808 for 1994, 1995 and 1996, respectively. Effective October 1, 1996, the
Company entered into a 35 month operating lease for additional corporate office
space. Lease payments for the additional office space approximate $189,000 per
year. Minimum rental commitments, excluding sublease income, under operating
leases as of June 30, 1996, with existing or renewable terms greater than one
year are as follows (the Company has $46,800 of minimum rental commitments due
in 1997 to related parties):

     CASH AND CASH EQUIVALENTS
 
     The Company maintains its cash balances in two financial institutions in
Maryland. At times the cash balances may exceed the federally insured limits.
The Company has not experienced any losses in such accounts and believes it is
not exposed to any significant credit risk on cash and cash equivalents.
 
   
NOTE 10--REDEEMABLE CONVERTIBLE PREFERRED STOCK
    
 
   
     The Company is authorized to issue 6.5% cumulative Series A shares and
9.75% cumulative Series B shares of redeemable convertible preferred stock at
June 30, 1996.
    
 
   
     PREFERRED STOCK CONVERSION AND REDEMPTION RIGHTS
    
 
   
     Both Series A Redeemable Convertible Preferred Stock and Series B
Redeemable Convertible Preferred Stock are convertible to Class C Common on a
share for share basis at the holder's option, at any time before February 25,
2000. In addition, the Preferred Stock is automatically converted to Class C
Common Stock on a share for share basis upon the occurrence of certain events,
including a public offering of the Company's stock. Only the fully-paid shares
are subject to conversion.
    
 
   
     Between March 1 and June 1, 2000, the Series A and Series B Redeemable
Convertible Preferred Stockholders have the right to require the Company to
redeem all of their shares at the greater of fair value (as determined by an
independent appraiser selected jointly by the parties) or the issuance price
plus unpaid dividends and interest thereon. Upon expiration of these rights, and
if the shares are not otherwise converted to Class C Common Stock, the Company
has the right to redeem the outstanding shares of Series A Preferred Stock at
the issuance price plus unpaid dividends and interest thereon. It may also
redeem the Series B Preferred Stock on the same terms that the holders could
require the Company to pay on a requested redemption by the holders.
    
 
   
     In addition, upon the occurrence of certain events, the Series A and Series
B Redeemable Convertible Preferred Stockholders have the right to require the
Company, and the Company has the right, to redeem all of the respective
preferred shares then held. In the event of any non-compliance (as defined) the
Preferred Stock is mandatorily redeemable. If the Company decides to take
certain actions without the approval of the Series A and Series B Redeemable
Convertible Preferred Stockholders then the Preferred Stockholders have the
right to require the Company to redeem all of their outstanding shares. In the
foregoing instances the redemption price is the greater of fair value or the
issuance price plus unpaid dividends and interest thereon. If the Company elects
to enforce certain non-competition covenants with the Series B Preferred
Stockholder, then the holder may require the Company to redeem the shares held
for the greater of $4.8 million or par value plus unpaid dividends and interest
thereon. If the Company issues Series A Junior Stock or Series B Junior Stock to
holders deemed to have interests adverse to the respective Preferred
Stockholder, then the holder may require the Company to redeem their shares at
the greater of: (i) the purchase price of the adverse junior stock on a fully
diluted basis, (ii) fair value, or (iii) one and one-half (1 1/2) times the
liquidation preference.
    
 
     SERIES A PREFERRED STOCK SUBSCRIPTION RECEIVABLE
 
   
     As partial consideration for the issuance of Series A Preferred Stock, the
Company received a note in the original amount of $3 million ($3 and $1.5
million balances outstanding at June 30, 1995 and 1996). The note bears interest
at 6.5% per annum, compounded quarterly, and interest is payable only to the
extent that the Company pays dividends on the Series A Preferred Stock. The
parties have the right to offset like amounts of dividends and interest.
    
 
   
     Scheduled note payments are subject to deferral at the option of the
Company until February 14, 1998, but interest continues to accrue on any unpaid
balance. As of June 30, 1996 the Company had elected to defer payments of
$375,000 scheduled for 1996. Upon redemption or conversion of Series A Preferred
Stock, any unpaid principal on the note is to be canceled in an amount equal to
five dollars times the number of shares converted or redeemed. The Company has
the option to require payment of any outstanding principal and interest on
February 14, 1998, or the Company may elect to redeem the outstanding Series A
Preferred Stock and cancel the remaining principal and interest.

     PREFERRED STOCK DIVIDENDS
 
   
     Series A Redeemable Convertible Preferred Stock accrues dividends quarterly
at the rate of thirty-two and one half cents ($0.325) per share per annum
beginning on February 24, 1995. Unpaid dividends accrue interest at the rate of
6.5% per annum, compounded quarterly, and may be offset by the Company against
any unpaid interest that is owed by the holders of the Series A Redeemable
Convertible Preferred Stock under the related note receivable.
    
 
   
     Series B Redeemable Convertible Preferred Stock accrues dividends quarterly
at the rate of one dollar and nine and seven tenths cents ($1.097) per share per
annum beginning December 1, 1995. Unpaid dividends accrue interest at the rate
of 9.75% per annum, compounded quarterly.
    
 
   
     Until April 1, 2000, payment of dividends on Series A Preferred Stock and
Series B Preferred Stock are only permitted in the event of redemption,
conversion or liquidation, and, in any event, dividends on Series B Preferred
Stock may only be paid after all dividends and interest on the Series A
Redeemable Convertible Preferred Stock have been satisfied. Beginning April 1,
2000, dividends on Series A Preferred Stock and Series B Preferred Stock will
accrue at a rate equal to the prime rate plus 100 basis points.
    
 
   
     Cumulative Series A and Series B Redeemable Convertible Preferred Stock
accrued and undeclared dividends at June 30 are as follows:

     The Company's cumulative Series A and Series B Preferred Stock are subject
to redemption; accordingly, for financial reporting purposes accrued dividends
are reflected as an accretion in the value of the preferred stock with a
corresponding reduction in stockholders' equity to reflect redemption value.
 
     PREFERRED STOCK LIQUIDATION PREFERENCES
 
     Upon liquidation or dissolution of the Company, the Series A and Series B
Preferred Stockholders are entitled to receive a liquidating distribution in an
amount equal to the greater of: (i) the fair value (as defined) per share of the
respective series of preferred stock or (ii) the original purchase price per
share of the respective stock. The distribution will also include all unpaid
cumulative dividends and accrued interest thereon; however, the total
distributable amount due to each preferred stockholder is limited to the amount
of cash paid to the Company for the purchase of the respective shares. No
distribution will be paid to the Series B Preferred Stockholder until all
amounts due to the Series A Preferred Stockholder have been fully paid.
 
NOTE 11--STOCKHOLDERS' EQUITY
 
   
     All of the Company stockholders are parties to an agreement dated December
1, 1995 (see Note 19 for September 4, 1996 amendment), that restricts transfer
of the Company stock. The agreement terminates upon occurrence of certain
specified events, including a public offering of the Company stock. Under the
terms of the stockholders' agreement, the Company may be required to purchase
shares of the Company's capital stock in certain circumstances, such as: (i)
Class A Common Stock owned by management stockholders, in the event of their
death or disability, if other management stockholders do not exercise their
rights to acquire the shares offered, in which case the Company is required to
purchase all of the offered shares at fair value (as agreed to by the parties or
as determined by an independent appraisal); (ii) Class A Common Stock purchased
by Dr. Rifkin or Dr. Kimmel after December 1, 1995, if their employment is
terminated, in which case the Company is required to purchase these shares at
fair value (as agreed to by the parties or as determined by an independent
appraisal); (iii) Class A Common Stock owned by other management stockholders if
their employment is terminated and the remaining management stockholders do not
exercise their rights to acquire the shares offered, then the Company is
required to purchase all of the shares offered. If termination is without cause,
the purchase price is based on fair value (as agreed to by the parties

or as determined by an independent appraisal). If termination is with cause,
then the purchase price is the lesser of $1 per share or the original issuance
cost of the shares. At June 30, 1996, 600,000 shares of Class A Common Stock
were subject to such repurchase requirement. If the Company is required to
purchase shares of the management stockholder under the foregoing circumstances,
then all accrued dividends due to Series A and Series B Preferred Stockholders
must first be paid; (iv) All classes of capital stock--upon the occurrence of an
involuntary transfer involving any of its outstanding capital stock, the Company
has the right of first refusal to purchase the offered shares at fair value (as
agreed to by the parties or as determined by an independent appraisal).
    

     All classes of Common Stock have the same preferences, rights and voting
powers. A portion of the Class A Common Stock is reserved for issuance upon
exercise of warrants, and a portion of the Class C Common Stock is reserved for
issuance to the holders of Series A Preferred Stock and Series B Preferred Stock
upon conversion of those shares of stock.

NOTE 12--STOCK OPTIONS
 
   
     The Company has an Omnibus Stock Plan (the Plan) which is accounted for
under APB Opinion 25 and related Interpretations with respect to employee
transactions and transactions with others. The Plan permits the Company to grant
incentive and non-qualified stock options, stock appreciation rights (SARs) and
restricted or unrestricted share awards to directors, officers, employees and
other key contributors to the Company. SARs entitle the optionee to surrender
unexercised stock options for cash or stock equal to the excess of the fair
value of the surrendered shares over the option value of such shares. The Plan
is administered by a committee (the Committee) appointed by the Company's Board
of Directors. Subject to adjustment as provided in the Plan, the aggregate
number of shares of the Company Common Stock which may be awarded is limited to
6,175,000. Shares under any grants that expire unexercised are available for
further grant.
    
 
     The exercise price and exercise period for stock options is determined by
the Committee, provided that the exercise period may not exceed 10 years from
the grant date and the exercise price for incentive stock options may not be
less than 100% of the fair value of the shares on the date the option is
granted. Incentive stock options are granted only to employees of the Company.
 
   
     In August and October 1995, the Company granted incentive stock options, to
purchase Class A Common Stock, to ten employees for a total of 118,380 shares at
the exercise price of $0.01 per share, the estimated fair value of the shares at
the date of grant based on the financial position and liquidity of the Company
and the limited marketability of the shares. The options become exercisable on
various dates ranging from April 1, 1996 through April 1, 2000. Upon exercise,
68,832 shares

will be fully vested and nonforfeitable; the remainder vest ratably over four
years. Options may expire or become exercisable, and shares issued may be fully
vested, at earlier dates upon occurrence of certain specified events, including
a change in control of the Company or the employee's death, disability,
retirement, or termination without cause. During 1996, employees forfeited
20,050 Class A Common Stock options.
    
 
   
     In December 1995, the Company granted non-qualified stock options to
purchase Class A Common Stock to three employees for a total of 12,500 shares at
the exercise price of $0.01 per share. The options become exercisable on
December 21, 1996. Upon exercise, 5,000 shares issued will be fully vested and
nonforfeitable; the remainder vest ratably over four years. Options may expire
or become exercisable, and shares issued may be fully vested, at earlier dates
upon occurrence of certain specified events, including a change in control of
the Company or the employee's death, disability, retirement, or termination
without cause. The Company will recognize compensation expense as the shares
vest in future periods, based upon the option price and fair value at the date
of grant. The fair value of the common stock at the time of grant in December
1995, $3.00 per share, was based on a discounted value of the per share price of
the Company's Series B Redeemable Convertible Preferred Stock.
    
 
   
     In May 1996, the Company granted incentive stock options to purchase Class
A Common Stock for 70,000 shares with an exercise price of $11.00 per share to
an employee, which was deemed to be in excess of management's estimate of fair
value at the date of grant.
    
 
   
     As of June 30, 1996, the Company has also granted options to purchase
105,000 shares of Class B Common Stock. In February 1995, the Company granted an
incentive stock option to purchase 100,000 shares of Class B Common Stock to an
officer of the Company at an exercise price of $0.01 per share, and in October
1995, the Company granted an incentive stock option to purchase 5,000 shares of
Class B Common Stock to a physician at an exercise price of $0.01 per share. The
estimated fair value of the stock was determined to be equal to the exercise
prices on the July 1994 and October 1995 grant dates.
    
 
NOTE 13--COMMON STOCK PURCHASE WARRANTS
 
   
     In consideration for the guarantee of a loan agreement, the Company issued
on December 1, 1995 a warrant to its Series B Preferred Stockholder for the
purchase of 88,889 shares of the Company Class A Common Stock at $5.625 per
share. The warrant expires on December 1, 2005 and is exercisable (i) if the
holder does not receive notice of a change in control within thirty days after
the change is effective or (ii) ninety days prior to the filing of a
registration statement for a public offering that includes shares held by
management stockholders. The warrant was valued at the present value of the
difference between the estimated fair value of the common stock subject to the
warrant and the aggregate strike price, discounted at the interest savings rate
(the difference between the rate obtained on the loan agreement and the rate of
interest that management believes would have been available without the
guarantee). At June 30, 1996, this amount ($370,000) is reflected as additional
paid-in capital and a deferred charge, which is being amortized on the interest
method over 25 months (the length of the guarantee).
    
 
   
     On December 1, 1995, in consideration for certain consulting services, the
Company issued warrants for the purchase of 24,000 shares of the Company common
stock at $11.25 per share (a price greater than management's estimate of fair
value at the date of grant). A value was not attributed to these warrants at the
time of issue. These warrants expire December 1, 2005, and are exercisable if
there is a change in control of the Company.
    
 
NOTE 14--FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts of financial instruments included in current assets
and current liabilities approximate fair values because of the short maturity of
those instruments. The following methods and assumptions were used to estimate
the fair value of each class of financial instruments for which it is
practicable to estimate that value:

NOTE 14--FAIR VALUE OF FINANCIAL INSTRUMENTS--CONTINUED
   
     REDEEMABLE CONVERTIBLE PREFERRED STOCK AND SERIES A PREFERRED STOCK
SUBSCRIPTION RECEIVABLE
    
 
     The Series A and Series B Preferred Stock are carried at issue price plus
accrued dividends, and have features unique to these securities including, but
not limited to, the right to appoint directors and the right to approve certain
significant activities of the Company. There is no quoted market price for the
Series A or Series B Preferred Stock.
 
     The carrying value of the Series A Preferred Stock subscription receivable
is based on the issue price of the related Series A Preferred Stock. In
December, 1995, the Company issued Series B Preferred Stock with the same rights
and privileges as the Series A Preferred Stock, other than the dividend rate and
related interest rate, for consideration greater than the per share value
received for the Series A Preferred Stock. Since both classes of Preferred Stock
are convertible to Class C Common Stock, it is not practical to determine if the
related stock subscription will be realized in cash, included in the conversion
to Common Stock or offset against the issued Series A Preferred Stock, thereby
reducing the number of shares outstanding. Furthermore, the Company has the
right to defer or cancel payment of the stock subscription receivable.
 
     LONG-TERM OBLIGATIONS
 
     Long-term obligations, excluding capital lease obligations, were incurred
by the Company when individual physicians joined the Company's core medical
groups. These notes are payable upon an initial public offering of the Company's
stock or a change in control as defined in the stockholders' agreement. The fair
value of these obligations is assumed to approximate recorded value because
there have not been any significant changes in circumstances since the
obligations were recorded.

NOTE 16--INCOME TAXES
 
   
     The Company has accumulated net losses from operations of $8,414,261.
Significant temporary differences between the determination of this loss for
financial reporting and income tax purposes include depreciation, the allowance
for uncollectible receivables, and certain accrued liabilities. These losses may
be carried forward for 15 years and expire at various dates through 2010. Under
federal tax law, certain changes in ownership of the Company, which may not be
within the Company's control, may operate to restrict future utilization of
these carryforwards. Since the ultimate realization of income tax benefits are
uncertain, they have been fully reserved at June 30, 1995 and 1996. Deferred tax
assets (liabilities) at June 30, 1995 and 1996, consist of the following:

facility (the "Bridge Loan Facility") with First National Bank of Maryland, N.A.
("First National"). The Bridge Loan Facility is collateralized by certain assets
of the Company and its affiliates and is guaranteed by the Series A Preferred
Stockholder. Advances under this facility bear interest at a rate of 6.71% per
annum. The Bridge Loan Facility matures on October 14, 1996 and management is
currently negotiating with First National to replace the Bridge Facility with a
$10,000,000 credit facility (the "First National Credit Facility"). As of
October 1, 1996, approximately $983,000 had been advanced under the Bridge Loan
Facility to fund corporate expenses in conjunction with the Company's strategy.
Although there can be no assurances the Company will obtain the First National
Credit Facility, the Company is proceeding with the loan approval process with
First National and the Company believes, based on conversations with First
National and the Series A Preferred Stockholder, if the loan approval process is
not completed before the maturity date of the Bridge Loan Facility, that the
maturity date will be extended until such time that the loan approval process is
completed. In the event the Company is unable or unwilling to secure the First
National Credit Facility or the maturity date of the Bridge Loan Facility is not
extended, the Bridge Loan Facility is expected to be repaid on or before October
14, 1996 from the Company's available cash.
    
 
     ACQUISITIONS
 
   
     The Company intends to continue its ongoing acquisition of primary care and
specialty practices. The Company is currently engaged in negotiations with
several providers of health care services. Certain of these acquisitions provide
for the purchase of the businesses under terms and conditions similar to those
that the Company has entered into previously. When the Company closes one of the
acquisitions that it is currently negotiating it will guarantee the indebtedness
of the business acquired of approximately $850,000 and assume $325,000 in
outstanding debt.
    
 
   
     The Company will issue approximately 483,000 shares of the Company's Class
B Common Stock having as estimated fair value of $3,381,000 as part of the
consideration paid on all of the businesses it is in negotiation with. Of this
total approximately 195,000 shares having an estimated fair value of $1,365,000
represent 10 limited partnership interests in MHLP and the remaining 288,000
shares to be issued by the Company have an estimated fair value of $2,016,000.
Certain of the individual physicians involved in these acquisitions will be
granted options to purchase additional shares of the Company's Class B Common
Stock in the event certain agreed upon performance criteria are met. These
agreements which have not yet closed provide for a total of 53,000 option
shares. In addition, 14,000 shares of Class B Common Stock have been reserved
for future issuance to physician employees of one of the practices purchased
subsequent to June 30, 1996.
    
 
   
     In the event that all of the acquisitions are consumated under the terms
currrently agreed upon the Company will acquire assets of approximately
$5,000,000.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
   
To Practices A:
    
 
   
     We have audited the accompanying statements of operations and cash flows of
Practice A (the "Practice") for the year ended December 31, 1994. These
financial statements are the responsibility of the Practice'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 statements of operations and cash flows
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statements of operations
and cash flows. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
presentation of the statements of operations and cash flows. We believe that our
audit of the statements of operations and cash flows provides a reasonable basis
for our opinion.
    
 
   
     In our opinion, the statements of operations and cash flows referred to
above present fairly, in all material respects, the results of operations and
cash flows of Practice A for the year ended December 31, 1994, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1994
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
   
     A summary of the significant accounting policies consistently applied in
the preparation of the accompanying financial statements is as follows:
    
 
BUSINESS
 
   
     Practice A (the "Practice") is a physician operating a private medical
practice.
    
 
BASIS OF ACCOUNTING
 
   
     The Practice presents its statements of operations and cash flows on the
accrual basis of accounting.
    
 
REVENUE RECOGNITION
 
     Revenues for services rendered are generated from direct patient payment
and third party billing and are recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between the customary and usual rates for physician services and
amounts reimbursable by government agencies (i.e., Medicare and Medicaid),
commercial insurance carriers and other health insurance programs.
 
   
     The majority of the Practices' revenues were derived from medical care
delivered on a fee for services basis. The Practice has negotiated agreements
with managed care organizations to provide physician services based on fee
schedules. No individual managed care organization is material to the Practice.
    
 
   
CASH AND CASH EQUIVALENTS
    
 
   
     For purposes of the statement of cash flows, the Practice considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.
    
 
   
DEPRECIATION METHOD
    
 
   
     The cost of property and equipment is depreciated over the estimated useful
lives of the related assets (5 years). Depreciation is computed using
accelerated methods.
    
 
MEDICAL SUPPLIES
 
   
     The Practice expenses the cost of routine medical and laboratory supplies
when purchased.
    
 
   
INCOME TAXES
    
 
   
     The Practice is an S Corporation ; accordingly, income tax liabilities are
the responsibility of the individual shareholder.
    
 
USE OF ESTIMATES
 
     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.
 
NOTE 2--OPERATING LEASE
 
   
     The Practice is the lessee of office space under an operating lease with a
partnership of which the shareholder is a limited partner. The lease expires in
2001.
    
 
   
     Minimum future rental payments under non-cancelable operating leases having
remaining terms in excess of one year amount to $33,582 for each of the next
five years.
    
 
   
     Rent expense paid for operating leases for the year ended December 31, 1994
was $19,261.

                                   PRACTICE A
    
 
                    NOTES TO FINANCIAL STATEMENTS--CONTINUED
 
NOTE 3--INCOME TAXES
 
   
     The Practice is an S Corporation. As a result, the Practice is not subject
to corporate income taxes, except for taxes on capital gains, if any.
Accordingly, no provisions have been made in the accompanying statement of
operations for federal and state income taxes since such taxes are liabilities
of the individual owner and the amounts thereof depend upon his tax situation.
    
 
   
     The Practices' tax returns are subject to examination by federal and state
taxing authorities. In the event of an examination of such tax returns, the
liability of the owners could be changed if adjustments in the distributable
income were ultimately sustained by the taxing authorities.
    
 
   
NOTE 4--COMMITMENTS AND CONTINGENCIES
    
 
MALPRACTICE INSURANCE
 
   
     The physicians employed by the Practice have claims made insurance coverage
for their professional malpractice claims which is paid for them by the
Practice. Such insurance provides for coverage to the extent individual claims
do not exceed $1,000,000 per incident and $3,000,000 in the aggregate per year,

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
    
 
   
To Practice B:
    
 
   
     We have audited the accompanying statements of operations and cash flows of
Practice B (the "Practice") for the year ended December 31, 1994. These
financial statements are the responsibility of the Practice'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 statements of operations and cash flows
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statements of operations
and cash flows. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
presentation of the statements of operations and cash flows. We believe that our
audit of the statements of operations and cash flows provides a reasonable basis
for our opinion.
    
 
   
     In our opinion, the statements of operations and cash flows referred to
above present fairly, in all material respects, the results of operations and
cash flows of Practice B for the year ended December 31, 1994, in conformity
with generally accepted accounting principles.

                               DECEMBER 31, 1994
    
 
   
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
     A summary of the significant accounting policies consistently applied in
the preparation of the financial statements is as follows:
    
 
   
BUSINESS
    
 
   
     Practice B (the "Practice") is a physician operating a private medical
practice.
    
 
   
BASIS OF ACCOUNTING
    
 
   
     The Practice presents its statements of operations and cash flows on the
accrual basis of accounting.
    
 
   
REVENUE RECOGNITION
    
 
   
     Revenues for services rendered are generated from direct patient payment
and third party billing and are recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between the customary and usual rates for physician services and
amounts reimbursable by government agencies (i.e., Medicare and Medicaid),
commercial insurance carriers and other health insurance programs.
    
 
   
     The majority of the practices' revenues were derived from medical care
delivered on a fee for services basis. The Practice has negotiated agreements
with managed care organizations to provide physician services based on fee
schedules. No individual managed care organization is material to the Practice.
    
 
   
CASH AND CASH EQUIVALENTS
    
 
   
     For the purposes of the statement of cash flows, the Practice considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.
    
 
   
DEPRECIATION METHOD
    
 
   
     The cost of property and equipment is depreciated over the estimated useful
lives of the related assets. Depreciation is computed using the accelerated
methods. The estimated useful lives for property plant and equipment are as
follows:
    
 
   
<TABLE>
<S>                                                                                <C>
Furniture and fixtures..........................................................   7 years
Computer equipment..............................................................   5 years
Office equipment................................................................   5 years
</TABLE>
    
 
   
MEDICAL SUPPLIES
    
 
   
     The Practice expenses the cost of routine medical and laboratory supplies
when purchased.
    
 
   
INCOME TAXES
    
 
   
     The Practice is a sole proprietorship; accordingly, income tax liabilities
are the responsibility of owner.
    
 
   
USE OF ESTIMATES
    
 
   
     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.
    
 
   
NOTE 2--OPERATING LEASE
    
 
   
     The Practice is the lessee of office space under an operating lease which
expires in 1995.
    
 
                                      F-32
 
<PAGE>
   
                                   PRACTICE B
    
 
   
                    NOTES TO FINANCIAL STATEMENTS--CONTINUED
    
 
NOTE 2--OPERATING LEASE--CONTINUED
   
     Minimum future rental payments under non-cancelable operating leases having
remaining terms in excess of one year amount to $7,548 in 1995.
    
 
   
     Rent expense paid for operating leases for the year ended December 31, 1994
was $14,311.
    
 
   
NOTE 3--INCOME TAXES
    
 
   
     The Practice is a sole proprietorship. As a result, the Practice is not
subject to corporate income taxes. Accordingly, no provisions have been made in
the accompanying statement of operations for federal and state income taxes
since such taxes are liabilities of the individual owner and the amounts thereof
depend upon his tax situation.
    
 
   
     The Practices' tax returns are subject to examination by federal and state
taxing authorities. In the event of an examination of such tax returns, the
liability of the owner could be changed if adjustments in the distributable
income were ultimately sustained by the taxing authorities.
    
 
   
NOTE 4--BENEFIT PLAN
    
 
   
     The Practice has a defined contribution plan covering employees who meet
the minimum length of service and age requirements. Contributions to the plan
amounted to $361 in 1994.
    
 
   
NOTE 5--COMMITMENTS AND CONTINGENCIES
    
 
   
MALPRACTICE INSURANCE
    
 
   
     The physician has claims made insurance coverage for professional
malpractice claims which is paid for by the Practice. Such insurance provides
for coverage to the extent individual claims do not exceed $1,000,000 per
incident and $3,000,000 in the aggregate per year, depending on the physician's
coverage.
    
 
   
NOTE 6--PROPRIETOR'S NET INCOME
    
 
   
     Proprietor's net income represents net income prior to owner's
compensation.
    
 
   
NOTE 7--SUBSEQUENT EVENT
    
 
   
     Effective June 1, 1995, Doctors Health System, Inc. of Owings Mills,
Maryland acquired certain assets of the Practice in an asset purchase
transaction.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
   
To Practice C:
    
 
   
     We have audited the accompanying statements of operations and cash flows of
Practice C (the "Practice") for the year ended December 31, 1994. These
financial statements are the responsibility of the Practice'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 statements of operations and cash flows
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statements of operations
and cash flows. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
presentation of the statements of operations and cash flows. We believe that our
audit of the statements of operations and cash flows provides a reasonable basis
for our opinion.
    
 
   
     In our opinion, the statements of operations and cash flows referred to
above present fairly, in all material respects, the results of operations and
cash flows of Practice C for the year ended December 31, 1994, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1994
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
   
     A summary of the significant accounting policies consistently applied in
the preparation of the financial statement is as follows:
    
 
BUSINESS
 
   
     Practice C (the "Practice") is a physician operating a private medical
practice.
    
 
BASIS OF ACCOUNTING
 
   
     The Practice presents its statements of operations and cash flows on the
accrual basis of accounting.
    
 
REVENUE RECOGNITION
 
     Revenues for services rendered are generated from direct patient payment
and third party billing and are recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between the customary and usual rates for physician services and
amounts reimbursable by government agencies (i.e., Medicare and Medicaid),
commercial insurance carriers and other health insurance programs.
 
   
     The majority of the Practices' revenues were derived from medical care
delivered on a fee for services basis. The Practice has negotiated agreements
with managed care organizations to provide physician services based on fee
schedules. No individual managed care organization is material to the Practice.
    
 
   
CASH AND CASH EQUIVALENTS
    
 
   
     For purposes of the statement of cash flows, the Practice considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.
    
 
DEPRECIATION METHOD
 
   
     The cost of property and equipment is depreciated over the estimated useful
lives of the related assets, which range from 5 to 7 years. Depreciation is
computed using the straight-line and the accelerated methods.
    
 
MEDICAL SUPPLIES
 
   
     The Practice expenses the cost of routine medical and laboratory supplies
when purchased.
    
 
   
INCOME TAXES
    
 
     The Practice is a sole proprietorship; accordingly, income tax liabilities
are the responsibility of owner.
 
USE OF ESTIMATES
 
     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.
 
NOTE 2--OPERATING LEASE
 
   
     The Practice is the lessee of office space under an operating lease which
expires in 1996.
    
 
     Minimum future rental payments under non-cancelable operating leases having
remaining terms in excess of one year amount to $25,470 in 1995 and $15,034 in
1996.
 
     Rent expense paid for operating leases for the year ended December 31, 1994
was $24,276.

                    NOTES TO FINANCIAL STATEMENTS--CONTINUED
 
NOTE 3--INCOME TAXES
 
   
     The Practice is a sole proprietorship. As a result, the Practice is not
subject to corporate income taxes. Accordingly, no provisions have been made in
the accompanying statement of operations for federal and state income taxes
since such taxes are liabilities of the individual owner and the amounts thereof
depend upon his tax situation.
    
 
   
     The Practices' tax returns are subject to examination by federal and state
taxing authorities. In the event of an examination of such tax returns, the
liability of the owner could be changed if adjustments in the distributable
income were ultimately sustained by the taxing authorities.
    
 
NOTE 4--BENEFIT PLAN
 
     The Practice has a defined contribution plan covering the employees.
Contributions to the plan amounted to $28,884 in 1994.
 
NOTE 5--COMMITMENTS AND CONTINGENCIES
 
MALPRACTICE INSURANCE
 
   
     The physicians employed by the Practice have insurance coverage for their
professional malpractice claims which is paid for them by the Practice. Such
insurance provides for coverage to the extent individual claims do not exceed
$1,000,000 per incident and $3,000,000 in the aggregate per year, depending on
the physician's coverage.
    
 
   
NOTE 6--PROPRIETOR'S NET INCOME
    
 
   
     Proprietor's net income represents net income prior to owner's
compensation.
    
 
   
NOTE 7--SUBSEQUENT EVENT
    
 
   
     Effective June 1, 1995, Doctors Health System, Inc. of Owings Mills,
Maryland acquired certain assets of the Practice in an asset purchase
transaction.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
   
To Practice D:
    
 
   
     We have audited the accompanying statements of operations and cash flows of
Practice D (the "Practice") for the year ended December 31, 1994. These
financial statements are the responsibility of the Practice'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 statements of operations and cash flows
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statements of operations
and cash flows. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
presentation of the statements of operations and cash flows. We believe that our
audit of the statements of operations and cash flows provides a reasonable basis
for our opinion.
    
 
   
     In our opinion, the statements of operations and cash flows referred to
above present fairly, in all material respects, the results of operations and
cash flows of Practice D, for the year ended December 31, 1994, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1994
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
   
     A summary of the significant accounting policies consistently applied in
the preparation of the financial statement is as follows:
    
 
BUSINESS
 
   
     Practice D (the "Practice") is a group physician medical practice.
    
 
BASIS OF ACCOUNTING
 
   
     The Practice presents its statements of operations and cash flows on the
accrual basis of accounting.
    
 
REVENUE RECOGNITION
 
     Revenues for services rendered are generated from direct patient payment
and third party billing and are recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between the customary and usual rates for physician services and
amounts reimbursable by government agencies (i.e., Medicare and Medicaid),
commercial insurance carriers and other health insurance programs.
 
     The Practice has agreements with various Health Maintenance Organizations
(HMO's) to provide medical services to subscribing participants. Under these
agreements, the Practice receives monthly capitation payments based on the
number of each HMO's participants, regardless of services actually performed by
the practice.
 
   
CASH AND CASH EQUIVALENTS
    
 
   
     For purposes of the statement of cash flows, the Practice considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.
    
 
DEPRECIATION METHOD
 
   
     The cost of property and equipment is depreciated over the estimated useful
lives of the related assets (7 years for furniture and equipment). Depreciation
is computed using the straight-line and the accelerated methods.
    
 
COVENANT NOT TO COMPETE
 
   
     The covenant not to compete relates to amounts paid to a former shareholder
upon his departure from the Practice. The agreement is being amortized on the
straight-line method over five years, which is equal to the term of the
agreement.
    
 
MEDICAL SUPPLIES
 
   
     The Practice expenses the cost of routine medical and laboratory supplies
when purchased.
    
 
   
INCOME TAXES
    
 
     The Practice is an S corporation; accordingly, income tax liabilities are
the responsibility of shareholders.
 
USE OF ESTIMATES
 
     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.
 
NOTE 2--LOSS ON ABANDONMENT OF ASSETS
 
   
     In October of 1994, the Practice entered into a lease agreement for new
office space (See Note 3). As a result of the new lease, the net book value of
the leasehold improvements of the existing lease have been written off as of
December 31, 1994.

NOTE 3--OPERATING LEASE
 
     In October 1994, the practice entered into an operating lease agreement for
approximately 2,942 square feet of office space. The lease expires in 2005.
 
     Minimum future rental payments under non-cancelable operating leases having
remaining terms in excess of one year amount to the following:

</TABLE>
    
 
     Rent expense paid for operating leases for the year ended December 31, 1994
was $34,625.
 
NOTE 4--INCOME TAXES
 
     The Practice is an S corporation. As a result, the Practice is not subject
to corporate income taxes, except for taxes on capital gains, if any.
Accordingly, no provisions have been made in the accompanying statement of
operations for federal and state income taxes since such taxes are liabilities
of the individual shareholders and the amounts thereof depend upon their tax
situation.
 
   
     The practices' tax returns are subject to examination by federal and state
taxing authorities. In the event of an examination of such tax returns, the
liability of the shareholder could be changed if adjustments in the
distributable income were ultimately sustained by the taxing authorities.
    
 
   
NOTE 5--COMMITMENTS AND CONTINGENCIES
    
 
MALPRACTICE INSURANCE
 
   
     The physicians employed by the Practice have insurance coverage for their
professional malpractice claims which is paid for them by the Practice. Such
insurance provides for coverage to the extent individual claims do not exceed
$1,000,000 per incident and $3,000,000 in the aggregate per year, depending on
the physician's coverage.
    
 
   
NOTE 6--SUBSEQUENT EVENT
    
 
   
     Effective December 1, 1995, Doctors Health System, Inc. of Owings Mills,
Maryland acquired certain assets of the Practice in an asset purchase
transaction.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
    
 
   
To Practice E:
    
 
   
     We have audited the accompanying statements of operations and cash flows of
Practice E (the "Practice") for the year ended April 30, 1995. These financial
statements are the responsibility of the Practice'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 statements of operations and cash flows
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statements of operations
and cash flows. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
presentation of the statements of operations and cash flows. We believe that our
audit of the statements of operations and cash flows provides a reasonable basis
for our opinion.
    
 
   
     In our opinion, the statements of operations and cash flows referred to
above present fairly, in all material respects, the results of operations and
cash flows of Practice E for the year ended April 30, 1995, in conformity with
generally accepted accounting principles.

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
     A summary of the significant accounting policies consistently applied in
the preparation of the financial statement is as follows:
    
 
   
BUSINESS
    
 
   
     Practice E (the "Practice") is a physician operating a private medical
practice.
    
 
   
BASIS OF ACCOUNTING
    
 
   
     The Practice presents its statements of operations and cash flows on the
accrual basis of accounting.
    
 
   
REVENUE RECOGNITION
    
 
   
     Revenues for services rendered are generated from direct patient payment
and third party billing and are recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between the customary and usual rates for physician services and
amounts reimbursable by government agencies (i.e., Medicare and Medicaid),
commercial insurance carriers and other health insurance programs.
    
 
   
     The majority of the Practices' revenues were derived from medical care
delivered on a fee for services basis. The Practice has negotiated agreements
with managed care organizations to provide physician services based on fee
schedules. No individual managed care organization is material to the Practice.
    
 
   
CASH AND CASH EQUIVALENTS
    
 
   
     For purposes of the statement of cash flows, the Practice considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.
    
 
   
DEPRECIATION METHOD
    
 
   
     The cost of property and equipment is depreciated over the estimated useful
lives of the related assets. Depreciation is computed using the accelerated
methods.
    
 
   
MEDICAL SUPPLIES
    
 
   
     The Practice expenses the cost of routine medical and laboratory supplies
when purchased.
    
 
   
INCOME TAXES
    
 
   
     The Practice is a C corporation. As a result, the Practice is subject to
corporate income taxes, including taxes on capital gains, if any. The Practice's
tax returns are subject to examination by federal and state taxing authorities.
    
 
   
USE OF ESTIMATES
    
 
   
     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
   
To Practice F:
    
 
   
     We have audited the accompanying statements of operations and cash flows of
Practice F (the "Practice") for the year ended December 31, 1995. These
financial statements are the responsibility of the Practice'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 statements of operations and cash flows
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statements of operations
and cash flows. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
presentation of the statements of operations and cash flows. We believe that our
audit of the statements of operations and cash flows provides a reasonable basis
for our opinion.
    
 
   
     In our opinion, the statements of operations and cash flows referred to
above present fairly, in all material respects, the results of operations and
cash flows of Practice F for the year ended December 31, 1995, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1995
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
   
     A summary of the significant accounting policies consistently applied in
the preparation of the financial statement is as follows.
    
 
BUSINESS
 
   
     Practice F (the "Practice") is a group medical practice providing medical
services.
    
 
BASIS OF ACCOUNTING
 
   
     The Practice presents its statements of operations and cash flows on the
accrual basis of accounting.
    
 
   
REVENUE RECOGNITION
    
 
     Revenues for services rendered are generated from direct patient payment
and third party billing and are recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between the customary and usual rates for physician services and
amounts reimbursable by government agencies (i.e., Medicare and Medicaid),
commercial insurance carriers and other health insurance programs.
 
   
     The majority of the Practices' revenues were derived from medical care
delivered on a fee for service basis. The Practice has negotiated agreements
with managed care organizations to provide physician services based on fee
schedules. No individual managed care organization is material to the Practice.
    
 
   
CASH AND CASH EQUIVALENTS
    
 
   
     For purposes of the statement of cash flows, the Practice considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.
    
 
DEPRECIATION METHOD
 
   
     The cost of property and equipment is depreciated over the estimated useful
lives of the related assets. Furniture and fixtures, computer equipment, and
office equipment are depreciated over useful lives ranging from 5 to 7 years.
Depreciation is computed using the straight-line and the accelerated methods.
    
 
MEDICAL SUPPLIES
 
   
     The Practice expenses the cost of routine medical and laboratory supplies
when purchased.
    
 
   
INCOME TAXES
    
 
   
     The Practice is a C corporation. As a result, the Practice is subject to
corporate income taxes, including taxes on capital gains, if any. The Practice's
tax returns are subject to examination by federal and state taxing authorities.
    
 
USE OF ESTIMATES
 
     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.
 
NOTE 2--OPERATING LEASE
 
   
     The Practice is the lessee of office space under operating leases with
terms through 2001.

                               DECEMBER 31, 1995
 
   
     Minimum future rental payments under non-cancelable operating leases having
remaining terms in excess of one year are as follows:

</TABLE>
    
 
   
     Rent expense paid for operating leases for the year ended December 31, 1995
was $89,741.
    
 
   
NOTE 3--LOSS ON DISPOSAL OF ASSETS
    
 
   
     During 1995 the Practice terminated the operation of a location it had
previously acquired. There being no remaining value associated with the assets,
the leasehold improvements and goodwill associated with said location were
expensed.
    
 
   
NOTE 4--INCOME TAXES
    
 
   
     The Practice is a C corporation for federal income tax purposes. The
physician owners of the Practice have a policy of distributing all residual
profits of the Practice as additional compensation. The Practice historically
has not incurred any significant income tax liabilities and there is no
indication that this trend will not continue in the future. Accordingly, the
Practice does not provide for income tax assets or liabilities.
    
 
   
NOTE 5--COMMITMENTS AND CONTINGENCIES
    
 
MALPRACTICE INSURANCE
 
   
     The physicians employed by the Practice have insurance coverage for their
professional malpractice claims which is paid for them by the Practice. Such
insurance provides for coverage to the extent individual claims do not exceed
$1,000,000 per incident and $3,000,000 in the aggregate per year, depending on
the physician's coverage.
    
 
   
NOTE 6--SUBSEQUENT EVENT
    
 
   
     Effective February 28, 1996, Doctors Health System, Inc. of Owings Mills,
Maryland acquired certain assets of the Practice in an asset purchase
transaction.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
   
TO PRACTICE G:
    
 
   
     We have audited the accompanying statements of operations and cash flows of
Practice G (the "Practice") for the year ended December 31, 1995. These
financial statements are the responsibility of the Practice'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 statements of operations and cash flows
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statements of operations
and cash flows. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
presentation of the statements of operations and cash flows. We believe that our
audit of the statements of operations and cash flows provides a reasonable basis
for our opinion.
    
 
   
     In our opinion, the statements of operations and cash flows referred to
above present fairly, in all material respects, the results of operations and
cash flows of Practice G for the year ended December 31, 1995, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1995
 
   
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
     A summary of the significant accounting policies consistently applied in
the preparation of the financial statement is as follows:
    
 
BUSINESS
 
   
     Practice G (the "Practice") is a physician operating a private medical
practice.
    
 
BASIS OF ACCOUNTING
 
     The Practice presents its statements of operations and cash flows on the
accrual basis of accounting
 
   
REVENUE RECOGNITION
    
 
     Revenues for services rendered are generated from direct patient payment
and third party billing and are recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between the customary and usual rates for physician services and
amounts reimbursable by government agencies (i.e., Medicare and Medicaid),
commercial insurance carriers and other health insurance programs.
 
   
     The majority of the Practices' revenues were derived from medical care
delivered on a fee for services basis. The Practice has negotiated agreements
with managed care organizations to provide physician services based on fee
schedules. No individual managed care organization is material to the Practice.
    
 
   
CASH AND CASH EQUIVALENTS
    
 
   
     For purposes of the statement of cash flows, the Practice considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.
    
 
DEPRECIATION METHOD
 
   
     The cost of property and equipment is depreciated over the estimated useful
lives of the related assets, which are 5 years for furniture and automobiles,
and 31.5 years for the office building. Depreciation is computed using the
straight-line method and the accelerated methods.
    
 
MEDICAL SUPPLIES
 
     The Practice expenses the cost of routine medical and laboratory supplies
when purchased.
 
INCOME TAXES
 
     The Practice is a sole proprietorship; accordingly, income tax liabilities
are the responsibility of owner.
 
USE OF ESTIMATES
 
     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.
 
   
NOTE 2--INCOME TAXES
    
 
     The Practice is a sole proprietorship. As a result, the Practice is not
subject to corporate income taxes. Accordingly, no provisions have been made in
the accompanying statement of operations for federal and state income taxes
since such taxes are liabilities of the individual owner and the amounts thereof
depend upon his tax situation.
 
                                      F-57

                                   PRACTICE G
    
 
                    NOTES TO FINANCIAL STATEMENTS--CONTINUED
 
   
NOTE 2--INCOME TAXES--CONTINUED
    
   
     The Practices' tax returns are subject to examination by federal and state
taxing authorities. In the event of an examination of such tax returns, the
liability of the owner could be changed if adjustments in the distributable
income were ultimately sustained by the taxing authorities.
    
 
   
NOTE 3--INTERNAL REVENUE SERVICE ASSESSMENTS
    
 
   
     The Proprietor has been assessed with past-due taxes, interest and
penalties in the amount of $164,000 as of December 31, 1995. This amount is not
related to the Practice and therefore has not been reflected in the accompanying
statement of operations.
    
 
   
NOTE 4--COMMITMENTS AND CONTINGENCIES
    
 
MALPRACTICE INSURANCE
 
   
     The physician has claims made insurance coverage for professional
malpractice claims which is paid for by the Practice. Such insurance provides
for coverage to the extent individual claims do not exceed $1,000,000 per
incident and $3,000,000 in the aggregate per year, depending on the physician's
coverage.
    
 
   
NOTE 5--PROPRIETOR'S NET INCOME
    
 
   
     Proprietor's net income represents net income prior to owner's
compensation.
    
 
   
NOTE 6--SUBSEQUENT EVENT
    
 
   
     Effective May 1, 1996, Doctors Health System, Inc. of Owings Mills,
Maryland acquired certain assets of the Practice in an asset purchase
transaction.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
   
To Practice H:
    
 
   
     We have audited the accompanying statements of operations and cash flows of
Practice H (the "Practice") for the year ended December 31, 1995. These
financial statements are the responsibility of the Practice'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 statements of operations and cash flows
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statements of operations
and cash flows. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
presentation of the statements of operations and cash flows. We believe that our
audit of the statements of operations and cash flows provides a reasonable basis
for our opinion.
    
 
   
     In our opinion, the statements of operations and cash flows referred to
above present fairly, in all material respects, the results of operations and
cash flows of Practice H for the year ended December 31, 1995, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1995
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
   
     A summary of the significant accounting policies consistently applied in
the preparation of the financial statement is as follows:
    
 
BUSINESS
 
   
     Practice H (the "Practice") is a physician operating a private medical
practice.
    
 
BASIS OF ACCOUNTING
 
   
     The Practice presents its statements of operations and cash flows on the
accrual basis of accounting.
    
 
REVENUE RECOGNITION
 
     Revenues for services rendered are generated from direct patient payment
and third party billing and are recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between the customary and usual rates for physician services and
amounts reimbursable by government agencies (i.e., Medicare and Medicaid),
commercial insurance carriers and other health insurance programs.
 
   
     The majority of the Practices' revenues were derived from medical care
delivered on a fee for services basis. The practice has negotiated agreements
with managed care organizations to provide physician services based on fee
schedules. No individual managed care organization is material to the Practice.
    
 
   
CASH AND CASH EQUIVALENTS
    
 
   
     For purposes of the statement of cash flows, the Practice considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.
    
 
DEPRECIATION METHOD
 
   
     The cost of property and equipment is depreciated over the estimated useful
lives of the related assets (5 years). Depreciation is computed using the
accelerated methods.
    
 
MEDICAL SUPPLIES
 
   
     The Practice expenses the cost of routine medical and laboratory supplies
when purchased.
    
 
INCOME TAXES
 
     The Practice is a sole proprietorship; accordingly, income tax liabilities
are the responsibility of owner.
 
USE OF ESTIMATES
 
     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.
 
NOTE 2--OPERATING LEASE
 
     The Practice is the lessee of office space under an operating lease with a
related party which expires in 1997.
 
     Minimum future rental payments under non-cancelable operating leases having
remaining terms in excess of one year amount to $15,000 in 1996 and $6,250 in
1997.
 
     Rent expense paid for operating leases for the year ended December 31, 1995
was $15,000.

                    NOTES TO FINANCIAL STATEMENTS--CONTINUED
 
                               DECEMBER 31, 1995
 
NOTE 3--INCOME TAXES
 
     The Practice is a sole proprietorship. As a result, the Practice is not
subject to corporate income taxes. Accordingly, no provisions have been made in
the accompanying statement of operations for federal and state income taxes
since such taxes are liabilities of the individual owner and the amounts thereof
depend upon his tax situation.
 
   
     The Practices' tax returns are subject to examination by federal and state
taxing authorities. In the event of an examination of such tax returns, the
liability of the owner could be changed if adjustments in the distributable
income were ultimately sustained by the taxing authorities.
    
 
NOTE 4--BENEFIT PLAN
 
     The Practice has a defined contribution plan covering the employees.
Contributions to the plan amounted to $831 in 1995.
 
NOTE 5--COMMITMENTS AND CONTINGENCIES
 
MALPRACTICE INSURANCE
 
   
     The physicians employed by the Practice have claims made insurance coverage
for their professional malpractice claims which is paid for them by the Company.
Such insurance provides for coverage to the extent individual claims do not
exceed $1,000,000 per incident and $3,000,000 in the aggregate per year,
depending on the physician's coverage.
    
 
   
NOTE 6--PROPRIETOR'S NET INCOME
    
 
   
     Proprietor's net income represents net income prior to owner's
compensation.
    
 
   
NOTE 7--SUBSEQUENT EVENT
    
 
   
     Effective May 1, 1996, Doctors Health System, Inc. of Owings Mills,
Maryland acquired certain assets of the Practice in an asset purchase
transaction.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
   
To Practice I:
    
 
   
     We have audited the accompanying balance sheets of Practice I (the
"Practice"), as of July 31, 1996 and 1995 and the related statements of
operations, stockholders' equity, and cash flows for the years then ended. These
financial statements are the responsibility of the Practice'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 audits 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 Practice I as of July 31,
1996 and 1995, and the results of their operations and their cash flows for the
years then ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

                                 JULY 31, 1996

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   
     A summary of the significant accounting policies consistently applied in
the preparation of the accompanying financial statements are as follows:
    

BUSINESS

   
     Practice I (the "Practice") is a Maryland corporation which was
incorporated on November 1, 1972 for the purpose of operating a private medical
practice.
    

BASIS OF ACCOUNTING

   
     The Practice presents its financial statements on the accrual basis of
accounting.
    

   
CASH AND CASH EQUIVALENTS
    

   
     For purposes of the statement of cash flows, the Practice considers all
highly liquid debt instruments purchased with a maturity date of three months or
less to be cash equivalents.
    

REVENUE RECOGNITION

     Revenues for services rendered are generated from direct patient payment
and third party billing and are recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between the customary and usual rates for physician services and
amounts reimbursable by government agencies (i.e., Medicare and Medicaid),
commercial insurance carriers and other health insurance programs.

   
     The majority of the Practices' revenues were derived from medical care
delivered on a fee for services basis. The Practice has negotiated agreements
with managed care organizations to provide physician services based on fee
schedules. No individual managed care organization is material to the Practice.
    

DEPRECIATION METHOD

   
     The cost of property and equipment is depreciated over the estimated useful
lives of the related assets which range from 5 to 7 years for furniture and
equipment. Leasehold improvements are amortized over the life of the lease.
Depreciation is computed using the straight-line and the accelerated methods.
    

MEDICAL SUPPLIES

     The Practice expenses the cost of routine medical and laboratory supplies
when purchased.

INCOME TAXES

   
     The Practice is taxable under the provisions of the Internal Revenue Code.
The Practice recognizes deferred income tax on all significant timing
differences between financial and income tax reporting.
    

USE OF ESTIMATES

     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.

2. MERGER OF PRACTICES

   
     Effective September 11, 1995, the Practice merged with another Maryland
medical corporation. The business combination was accounted for by the
pooling-of-interest method.
    

                                      F-69

                                   PRACTICE I
    

                    NOTES TO FINANCIAL STATEMENTS--CONTINUED

2. MERGER OF PRACTICES--CONTINUED
   
     Effective August 8, 1996, a medical corporation which merged in 1995,
exercised its option to withdraw from the Practice, as permitted under the
Agreement of Merger. Under the terms of the withdrawal, the withdrawing medical
corporation departs with the same stockholders' equity it had when the merger
occurred. The departing firm receives their fixed assets, as well as a note
collateralized by one of the fixed assets, and the remaining equity balance will
be paid through a deferred compensation arrangement. This deferred compensation
arrangement is fully accrued at July 31, 1996.
    

   
     Since the merger has been rescinded and the departing corporation is not a
participant in the acquisition disclosed in Note 7, the assets, liabilities and
operations of the withdrawing corporation have not been included herein.
    

3. INCOME TAXES

   
     The Practice accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109. Deferred tax assets consist of the
following:

                                                                                                       $(249,048)   $(473,828)
                                                                                                       ---------    ---------
                                                                                                       ---------    ---------
</TABLE>
    

   
     The variance in the tax rate reflected in the financial statements compared
to the combined federal and state statutory rate is primarily related to the
cash basis of accounting for income tax purposes.
    

4. OPERATING LEASES

   
     The Practice conducts its operations at leased facilities and uses leased
office equipment under noncancelable operating leases. The operating leases have
initial terms that expire at various periods through 2001 and, generally,
provide for renewal for various periods at stipulated rates. Some of the
operating leases provide that the Practice pay taxes, maintenance, insurance,
and other occupancy costs applicable to leased premises. Total rent expense for
all operating leases approximated $369,569 in 1996 and $307,637 in 1995. Minimum
rental commitments, excluding sublease income, under operating leases as of July
31, 1996 are as follows:

5. COMMITMENTS AND CONTINGENCIES

MALPRACTICE INSURANCE

   
     The physicians in the Practice have claims made insurance coverage for
professional malpractice claims which is paid for by the Practice. Such
insurance provides for coverage to the extent individual claims do not exceed
$1,000,000 per incident and $3,000,000 in the aggregate per year, depending on
the physician's coverage.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

   
To Practice J:
    

   
     We have audited the accompanying combined balance sheet of Practice J (the
"Practice") as of June 30, 1996 and the related combined statements of
operations, stockholders' equity, and cash flows for the year then ended. These
financial statements are the responsibility of the Practice'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 audits provide a reasonable basis for our opinion.

   
     In our opinion, the financial statements referred to above, present fairly,
in all material respects, the combined financial position of Practice J as of
June 30, 1996, and the combined results of their operations and their combined
cash flows for the year then ended, in conformity with generally accepted
accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
    

                                 JUNE 30, 1996

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   
     A summary of the significant accounting policies consistently applied in
preparation of the financial statements are as follows:
    

BASIS OF ACCOUNTING

   
     Practice J (the "Practice") is engaged in the business of providing health
care services and managing physician practices.
    

   
     The Practice presents its combined financial statements on the accrual
basis of accounting.
    

PRINCIPLES OF COMBINATION

   
     The accompanying combined financial statements include the accounts of
multiple entities which are under common control.
    

     Significant intercompany transactions and balances have been eliminated in
the combined financial statements.

   
CASH EQUIVALENTS
    

   
     For purposes of the statement of cash flows, the Practice considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.
    

   
     During the year ended June 30, 1996, the Practice maintained cash balances
in several local banks. At times these balances exceeded the federally insured
limits. The Practice has not experienced any losses in such accounts and
believes it is not exposed to any significant credit risk on cash and cash
equivalents.
    

REVENUE RECOGNITION

     Revenues for services rendered are generated from direct patient payment
and third party billing and are recognized when services are performed. These
revenues are recorded net of adjustments and allowances resulting from the
difference between the customary and usual rates for physician services and
amounts reimbursable by government agencies (i.e., Medicare and Medicaid),
commercial insurance carriers and other health insurance programs.

   
     The majority of the Practices' revenues were derived from medical care
delivered on a fee for services basis. The Practice has negotiated agreements
with managed care organizations to provide physician services based on fee
schedules. No individual managed care organization is material to the Practice.
    

   
ACCOUNTS RECEIVABLE
    

   
     Accounts receivable consist of amounts due from federal and state
government agencies, commercial insurance companies, other health insurance
programs and private pay patients. Accounts receivable reflect an allowance for
uncollectible accounts based on historical information, current payor mix, and
trends in the health care industry.
    

   
DEPRECIATION METHOD
    

     Property and equipment are stated at cost. Depreciation and amortization
are provided for in amounts sufficient to relate the cost of depreciable assets
to operations over their estimated service lives. The straight-line method of
depreciation is followed for substantially all assets for financial reporting
purposes and accelerated methods are used for tax purposes. Routine maintenance
and repairs are charged to expense as incurred.

MEDICAL SUPPLIES

   
     The Practice expenses the cost of routine medical and laboratory supplies
when purchased.
    

                                      F-77

               NOTES TO COMBINED FINANCIAL STATEMENTS--CONTINUED
    

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--CONTINUED
INCOME TAXES

     The Practice is not a taxpaying entity for federal income tax purposes, and
thus no income tax expense has been recorded on the statement of operations.
Income from the partnership is taxed to the physicians through their individual
returns.

USE OF ESTIMATES

     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.

   
2. NOTES PAYABLE
    

   
     The Practice has $1,759,727 in Notes Payable which are payable on demand.
The bank has not called the notes at the statement date and the Practice is
currently negotiating a refinance and consolidation.
    

   
     The Practice has a $300,000 note payable which matures March 1, 1997. The
Practice pays 8.25% interest only on this note monthly.
    

   
3. INCOME TAXES
    

   
     The Practice entities have elected to adopt the provisions of Subchapter S
of the Internal Revenue Code of 1986 or to be taxed as partnerships. As a
result, the Practice is not subject to corporate income taxes, except for taxes
on certain capital gains, if any. Accordingly, no provisions have been made in
the accompanying statement of operations for federal and state income taxes
since such taxes are liabilities of the individual stockholder and the amounts
thereof depend upon his tax situation.
    

   
     The Practices' tax returns are subject to examination by federal and state
taxing authorities. In the event of an examination of such tax returns, the
liability of the stockholder could be changed if adjustments in the
distributable income were ultimately sustained by the taxing authorities.
    

   
4. COMMITMENTS AND CONTINGENCIES
    

     MALPRACTICE INSURANCE

   
     The physicians employed by the Practice have insurance coverage for their
professional malpractice claims which is paid for them by the Practice. Such
insurance provides for coverage to the extent individual claims do not exceed
$1,000,000 per incident and $3,000,000 in the aggregate per year, depending on
the physician's coverage.
    

   
     Upon termination of employment, physicians are not required to purchase
insurance coverage for the remaining outstanding exposure related to incidents
which may be incurred, but reported subsequent to the termination of their
employment. Accordingly, the Practice has reserved to provide for this self
insured exposure.
    

   
5. STOCKHOLDERS' (DEFICIT)
    

   
     The combined equity of Practice J consists of the equity in five medical
practices. The owners equity of the practices comprising Practice J are as
follows:

                      FINANCIAL STATEMENTS (UNAUDITED) OF

              DOCTORS HEALTH SYSTEM, INC. AND ACQUIRED BUSINESSES

   
     The following pro forma consolidated balance sheet as of June 30, 1996, and
the pro forma consolidated statement of operations for the year ended June 30,
1996, give effect to (1) issuance of Series C Redeemable Convertible Preferred
Stock subsequent to June 30, 1996, (2) the acquisition of physician practices
during the year ended June 30, 1996, (3) the acquisition of physician practices
subsequent to June 30, 1996 and (4) the proposed acquisition of physician
practices subsequent to June 30, 1996, which are probable (collectively the
"Acquired Businesses") by Doctors Health System, Inc. (DHS). These transactions
are reflected as of June 30, 1996 for the pro forma consolidated balance sheet
and as of July 1, 1995, for the pro forma consolidated statements of operations.
The pro forma information is based on the respective historical financial
statements of Doctors Health System, Inc. and the Acquired Businesses, giving
effect to the completed and proposed acquisitions under the purchase method of
accounting and the assumptions and adjustments described in the accompanying
notes to the pro forma consolidated financial statements.
    

   
     The unaudited pro forma consolidated financial statements have been
prepared by the DHS based on the audited financial statements of certain of the
acquisitions or probable acquisitions, which statements are included elsewhere
in this Prospectus, and the unaudited financial statements of other acquisitions
or probable acquisitions, which statements are not included herein (as they are
not significant), adjusted where necessary, with respect to pre-acquisition
periods, to the basis of accounting used in the DHS's Audited Financial
Statements.
    

   
     Management of DHS does not believe that the pro forma consolidated
financial statements are indicative of the results that actually would have
occurred if the combinations had been in effect on the dates indicated or which
may be obtained in the future. The pro forma consolidated financial statements
should be read in conjunction with the financial statements and notes of DHS and
the respective Acquired Businesses contained elsewhere herein.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 2-418 of the Maryland General Corporation Law (the "MGCL") provides
that the Registrant may indemnify any director who was, is or is threatened to
be made a named defendant or respondent to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative by reason of the fact that he is or was a director of the
Registrant, or while a director, is or was serving at the request of the
Registrant as a director, officer, partner, trustee, employee or agent of
another foreign or domestic corporation, partnership, joint venture, trust,
other enterprise or employee benefit plan, against reasonable expenses
(including attorneys' fees), judgments, penalties, fines and settlements,
actually incurred by the director in connection with such action, suit or
proceeding, unless it is established that: (i) the act or omission of the
director was material to the matter giving rise to such action, suit or
proceeding, and was committed in bad faith or was the result of active and
deliberate dishonesty; (ii) the director actually received an improper personal
benefit in money, property or services; or (iii) in the case of any criminal
proceeding, the director had reasonable cause to believe that the act or
omission was unlawful. If the action, suit or proceeding was one by or in the
right of the Registrant, no indemnification shall be made with respect to any
action, suit or proceeding in which the director shall have been adjudged to be
liable to the Registrant. A director also may not be indemnified with respect to
any action, suit or proceeding charging improper personal benefit to the
director, whether or not involving action in the director's official capacity,
in which the director is adjudged to be liable on the basis that a personal
benefit was improperly received. Unless limited by the Registrant's Charter: (i)
a court of appropriate jurisdiction, upon application of a director, may order
such indemnification as the court shall deem proper if it determines that the
director is fairly and reasonably entitled to indemnification in view of all of
the relevant circumstances, regardless of whether the director has met the
standards of conduct required by Section 2-418; and (ii) the Registrant shall
indemnify a director if such director is successful on the merits or otherwise
in defense of any action, suit or proceeding referred to above. However, with
respect to any action, suit or proceeding by or in the right of the Registrant
or in which the director was adjudged to be liable on the basis that a personal
benefit was improperly received, the Registrant may only indemnify the director
for any expenses (including, attorneys' fees) incurred in connection with such
action, suit or proceeding.
 
     Section 2-418 of the MGCL further provides that unless limited by the
Registrant's Charter, the Registrant: (i) shall (a) indemnify an officer of the
Registrant if such officer is successful on the merits or otherwise in defense
of any action, suit or proceeding referred to above, and (b) indemnify an
officer of the Registrant if a court of appropriate jurisdiction, upon
application of an officer, shall order indemnification; (ii) may indemnify and
advance expenses to an officer, employee or agent of the Registrant to the same
extent that it may indemnify directors; and (iii) may indemnify and advance
expenses to an officer, employee or agent who is not a director to such further
extent, consistent with law, as may be provided by the Charter, Bylaws, general
or specific action of the Registrant's Board of Directors or contract.
 
     The Registrant's Bylaws provide that, to the maximum extent permitted by
the MGCL, as from time to time amended, the Registrant shall indemnify (i) its
current and former directors, officers, agents and employees, and (ii) those
persons who, at the request of the Registrant, serve or have served another
corporation, partnership, joint venture, trust or other enterprise in one or
more of such capacities, against any and all liabilities incurred in connection
with their services in such capacities,
 
                                      II-1
 
<PAGE>
to the extent determined appropriate by the Board of Directors. The Bylaws
further provide that, to the extent required by the Charter or applicable law,
the Registrant shall indemnify such individuals.
 
     The Registrant's Charter provides that, to the fullest extent permitted by
the MGCL, as amended or interpreted, no director or officer of the Registrant
shall be personally liable to the Registrant or its stockholders for monetary
damages in connection with events occurring at the time such person served as a
director or officer. The Registrant's Charter also provides that, to the maximum
extent permitted by the MGCL, as from time to time amended, the Registrant shall
indemnify its current and former directors and officers against any and all
liabilities and expenses incurred in connection with their services in such
capacities. The Registrant also may, if approved by the Board of Directors,
indemnify officers, employees, agents and persons who serve or have served at
its request with another corporation, partnership or other entity.
 
     The provisions in the Charter and Bylaws do not eliminate the duty of care.
In appropriate circumstances, equitable remedies such as injunctive or other
forms of non-monetary relief remain available under Maryland law. In addition,
each director will continue to be subject to liability for breach of the
director's duty of loyalty to the Registrant or its stockholders, for acts or
omissions not in good faith or involving intentional misconduct or knowing
violations of law, for actions leading to improper personal benefit to the
director and for payment of dividends or approval of stock repurchases or
redemptions that are unlawful under the MGCL. These provisions also do not
affect a director's or officer's responsibilities under any other law, such as
the federal or state securities laws or state or federal environmental laws.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes:
 
                                      II-4
 
<PAGE>
     (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 and 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 represents no more than 20 percent 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 of 1933, each such post-effective amendment shall be deemed to be a new
Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial BONA
FIDE offering thereof.
    
 
     (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

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than 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 counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

requiring the vote of stockholders of the Corporation under the MGCL, the
affirmative vote of stockholders holding two-thirds (2/3) of the shares of
outstanding capital stock of the Corporation shall be required to authorize
approval of such matters. The preferences, voting powers, restrictions,
limitations as to dividends, rights and qualifications of the Common Stock,
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Preferred Stock are as follows:

                                       2

         A.       COMMON STOCK.

                  Except as expressly set forth herein, shares of Class A Common
Stock, shares of Class B Common Stock and shares of Class C Common Stock shall
have the same preferences, rights and voting powers, and shall be identical in
all respects and will entitle the holders thereof to the same rights and
privileges. Sufficient shares of Class C Common Stock shall from time to time be
reserved by the Corporation for issuance to the holders of the shares of Series
A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock upon
conversion of all of the shares of Series A Preferred Stock, Series B Preferred
Stock and Series C Preferred Stock into shares of Class C Common Stock.

                  1.       VOTING RIGHTS.

                           General Provisions. Except as otherwise provided
herein, every holder of Common Stock shall be entitled to cast, in person or by
proxy, one vote for each share of Common Stock held of record by such holder on
all matters to be voted on by stockholders. The holders of shares of Common
Stock shall vote together with the holders of shares of Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock on all matters
submitted to a vote of stockholders and not as a separate series or class,
except as otherwise provided herein.

                           (b) Class A Common Stock. The holders of shares of
Class A Common Stock, voting as a single class, shall be entitled to elect five
(5) directors of the Corporation (the "Class A Common Directors"). The
affirmative vote of a majority of the shares of Class A Common Stock represented
in person or by proxy at a meeting at which a quorum of Class A Common Stock is
present shall be sufficient to approve any matter with respect to which such
holders are entitled to vote; provided, however, that the affirmative vote of a
plurality of all votes cast shall be sufficient to elect a Class A Common
Director. Each share of Class A Common Stock may be voted for as many
individuals as there are Class A Common Directors to be elected. The holders of
Class A Common Stock, at any annual meeting or upon a call of a special meeting
of holders of Class A Common Stock by holders of not less than twenty-five
percent (25%) of the shares of Class A Common Stock then outstanding, may remove
any Class A Common Director at any time and from time to time with or without
cause, voting as a single class, by the affirmative vote of eighty percent (80%)
of all of the votes entitled to be cast for the election of a Class A Common
Director, and may elect a successor to fill any resulting vacancies for the
remainder of the term of such director. If any Class A Common Director shall
cease to be a director for any reason (including death, resignation, removal or
any other cause), the vacancy shall be filled by a vote of the remaining Class A
Common Directors (unless, with respect to removal, the holders of Class A Common
Stock have elected a successor Class A Common Director pursuant to the
provisions hereof). If there are no such remaining directors, then upon a call
of a 


                                       3

<PAGE>

special meeting of holders of Class A Common Stock, by any such holder, the
vacancy shall be filled by the vote of the holders of Class A Common Stock,
voting as a single class.

                           (c) Class B Common Stock. The holders of shares of
Class B Common Stock, voting as a single class, shall be entitled to elect eight
(8) directors of the Corporation (the "Class B Common Directors"). The
affirmative vote of a majority of the shares of Class B Common Stock represented
in person or by proxy at a meeting at which a quorum of Class B Common Stock is
present shall be sufficient to approve any matter with respect to which said
holders are entitled to vote; provided, however, that the affirmative vote of a
plurality of all votes cast shall be sufficient to elect a Class B Common
Director. Each share of Class B Common Stock may be voted for as many
individuals as there are Class B Common Directors to be elected. The holders of
Class B Common Stock, at any annual meeting or upon a call of a special meeting
of holders of Class B Common Stock by holders of not less than twenty-five
percent (25%) of the shares of Class B Common Stock then outstanding, may remove
any Class B Common Director at any time and from time to time with or without
cause, voting as a single class, by the affirmative vote of a majority of all of
the votes entitled to be cast for the election of a Class B Common Director, and
may elect a successor to fill any resulting vacancies for the remainder of the
term of such director. If any Class B Common Director shall cease to be a
director for any reason (including death, resignation, removal or any other
cause), the vacancy shall be filled by a vote of the remaining Class B Common
Directors (unless, with respect to removal, the holders of Class B Common Stock
have elected a successor Class B Common Director pursuant to the provisions
hereof). If there are no such remaining directors, then upon a call of a special
meeting of holders of Class B Common Stock, by any such holder, the vacancy
shall be filled by the vote of the holders of Class B Common Stock, voting as a
single class.

                           (d) Class C Common Stock. Upon conversion of all of
the shares of Series A Preferred Stock then outstanding into shares of Class C
Common Stock, the holders of Shares of Class C Common Stock who were formerly
holders of Series A Preferred Stock ("Converted Series A Class C Common
Stockholders"), voting as a single sub-class, shall be entitled to elect two (2)
Directors of the Corporation ("Converted Series A Class C Common Directors").
Upon conversion of all of the shares of Series B Preferred Stock then
outstanding into shares of Class C Common Stock, the holders of shares of Class
C Common Stock who were formerly holders of Series B Preferred Stock ("Converted
Series B Class C Common Stockholders"), voting as a single sub-class, shall be
entitled to elect two (2) Directors of the Corporation ("Converted Series B
Class C Common Directors"). Upon conversion of all of the shares of Series C
Preferred Stock then outstanding into shares of Class C Common Stock, the
holders of shares of Class C Common Stock who were formerly holders of Series C
Preferred Stock ("Converted Series C Class C Common Stockholders"), voting 

                                       4

<PAGE>


as a single sub-class, shall be entitled to elect one (1) Director of the
Corporation prior to the Corporation's 1998 annual meeting of shareholders and
two (2) Directors thereafter ("Converted Series C Class C Common Directors"). It
is the intent of this Section that upon conversion of all of the shares of
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
then outstanding into shares of Class C Common Stock, the holders of shares of
Class C Common Stock, separately voting as sub-classes, shall be entitled to
elect five (5) Directors prior to the Corporation's 1998 annual meeting of
shareholders and six (6) Directors thereafter (all such directors elected by the
holders of Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock being hereinafter referred to as the "Class C Common
Directors"). The affirmative vote of a majority of the shares of Class C Common
Stock represented in person or by proxy at a meeting at which a quorum of Class
C Common Stock is present shall be sufficient to approve any matter with respect
to which said holders are entitled to vote, except for matters relating to the
election or removal of directors. When the Converted Series A Class C Common
Stockholders, the Converted Series B Class C Common Stockholders or Converted
Series C Class C Common Stockholders vote on the election of Converted Series A
Class C Common Directors, Converted Series B Class C Common Directors or
Converted Series C Class C Common Directors, respectively, the affirmative vote
of a plurality of all votes cast shall be sufficient to elect a Converted Series
A Class C Common Director, Converted Series B Class C Common Director, or
Converted Series C Class C Common Director, respectively. Each share of
Converted Series A Class C Common Stock, Converted Series B Class C Common Stock
and Converted Series C Class C Common Stock may be voted for as many individuals
as there are Converted Series A Class C Common Directors, Converted Series B
Class C Common Directors and Converted Series C Class C Common Directors,
respectively, to be elected. At any annual meeting or upon a call of a special
meeting of holders of Converted Series A Class C Common Stock, Converted Series
B Class C Common Stock or Converted Series C Class C Common Stock by holders of
not less than twenty-five percent (25%) of the shares of Converted Series A
Class C Common Stock, Converted Series B Class C Common Stock or Converted
Series C Class C Common Stock then outstanding, the Converted Series A Class C
Common Stockholders, Converted Series B Class C Common Stockholders or the
Converted Series C Class C Common Stockholders may remove any Converted Series A
Class C Common Director, Converted Series B Class C Common Director or Converted
Series C Class C Common Director, respectively, at any time and from time to
time with or without cause, voting as sub-class, by the affirmative vote of
eighty percent (80%) of all of the votes entitled to be cast for the election of
a Converted Series A Class C Common Director, Converted Series B Class C Common
Director or Converted Series C Class C Common Director, respectively, and may
elect a successor to fill any resulting vacancies for the remainder of the term
of such director. If any Converted Series A Class C Common Director, Converted
Series B Class C Common Director or Converted Series C Class C Common Director
shall cease to be a director for any reason (including death, resignation,
removal or any other cause), the 

                                       5

<PAGE>



vacancy shall be filled by a vote of the remaining Converted Series A Class C
Common Director, Converted Series B Class C Common Director or Converted Series
C Class C Common Director (unless with respect to removal, the holders of
Converted Series A Class C Common Stock, Converted Series B Class C Common Stock
or Converted Series C Class C Common Stock have elected a successor Converted
Series A Class C Common Director, Converted Series B Class C Common Director or
Converted Series C Class C Common Director pursuant to the provisions hereof).
If there is no such remaining director, then upon a call of a special meeting of
holders of Converted Series A Class C Common Stock, Converted Series B Class C
Common Stock or Converted Series C Class C Common Stock, by any such holder, the
vacancy shall be filled by the vote of the holders of Converted Series A Class C
Common Stock, Converted Series B Class C Common Stock or Converted Series C
Class C Common Stock, voting as a sub-class.

                           (e) Effect of Conversion. Upon conversion of all of
the shares of Common Stock into shares of Class A Common Stock pursuant to
Section A.4 of this Article IV, every such holder of Class A Common Stock shall
be entitled to cast, in person or by proxy, one vote for each share of Class A
Common Stock held of record by such holder on all matters to be voted on the
Stockholders and none of the additional voting rights provided to holders of
shares of Common Stock pursuant to Section A.1(b), (c) and (d) of this Article
IV, or to holders of the Series A Preferred Stock, Series B Preferred Stock or
Series C Preferred Stock pursuant to Section B.1, Section C.1 and/or Section D.1
of this Article IV, shall be applicable to such Class A Common Stock or to
holders thereof. From and after such conversion, none of the rights to
dividends, redemption, conversion or liquidation applicable to the Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock pursuant
to Sections B.2-5, C.2-5 and D.2-5 of this Article IV shall be applicable to
such Class A Common Stock or to any holder thereof. Such Class A Common Stock
shall have the dividend rights and liquidation rights set forth in Sections 2
and 3 of this Article IV.A.

                           2.     DIVIDENDS.

                           Subject to the provisions of law and these Articles,
dividends may be declared and paid on the Common Stock of the Corporation at
such time and in such amounts as the Board of Directors may deem advisable,
provided, in all events, that no dividends may be paid with respect to shares of
Common Stock until such time as all shares of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock have been redeemed by the
Corporation or converted into shares of Common Stock as provided herein,
including therein payment of all accrued and unpaid dividends on said shares of
Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock.

                           3.       LIQUIDATION RIGHTS.

                           In the event of the dissolution, liquidation or
winding up of the Corporation, whether voluntary or involuntary, after payment
or provision for payment of the debts and other liabilities of the Corporation
and the preferential amounts required to be paid to the holders of Series A
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock, as
provided for in Sections B.5, C.5 and D.5 of this Article IV, each share of
Common Stock shall be entitled to share ratably with all other shares of Common
Stock in all remaining net assets of the Corporation.

                  4.       CONVERSION OF CLASS A COMMON STOCK, CLASS B COMMON
                           STOCK, AND CLASS C COMMON STOCK.

                  Simultaneously with the consummation of any Qualified or
Non-Qualified Public Offering (as such terms are defined in Section B.1.(d)
below) effected by the Corporation in accordance with the provisions of Sections
B, C and D of this Article IV, each share of the Corporation's Class A Common
Stock, Class B Common Stock, and Class C Common Stock shall be converted,
without any action on the part of the holder thereof or the Corporation, into an
identical share of the Corporation's Class A Common Stock, and all references in
these articles to Class A, Class B and Class C Common Stock, respectively, shall
be deemed to refer to the Corporation's Class A Common Stock, and all special
rights granted to the holders of Class A, Class B, and Class C Common Stock and
to all holders of Series A Preferred Stock, Series B Preferred Stock and Series
C Preferred Stock hereunder shall cease and terminate. At least twenty (20) days
prior written notice of the date fixed and place determined for conversion shall
be sent by first class mail, postage prepaid, to the address of every holder of
shares of Common Stock as shown in the records of the Corporation. On or before
the date fixed for conversion, each holder of shares of Common Stock shall
surrender the Certificates representing such shares to the Corporation at the
place designated in such notice and shall thereafter receive certificates for
the number of full shares of Class A Common Stock to which such holder is
entitled.

                  5.       CERTAIN PERMITTED REDEMPTIONS.

                  Notwithstanding anything herein to the contrary, the
Corporation shall be permitted to effect redemptions (each a "Permitted
Redemption") of its capital stock without the consent or approval of the Series
A Preferred Directors, the Series B Preferred Directors, the Series C Preferred
Directors, the holders of Series A Preferred Stock, the holders of the Series B
Preferred Stock or the holders of Series C Preferred Stock, and without granting
to the Series A Preferred Stockholders, the Series B Preferred Stockholders or
the Series C Preferred Stockholders any redemption or other rights (other than
as set forth below):


                                       7

<PAGE>


                           (a) upon the payment in full of all accumulated and
unpaid accrued dividends and interest on all outstanding shares of Series A
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock for all
past dividend periods and the then current dividend period, to effect a
redemption of shares of Class A Common Stock owned by any Management Stockholder
(as defined in Section B.1(c)(iv) hereof) as and to the extent required by
Section 4 of such Management Stockholder's Management Employment Agreement (as
defined in Section B.1(c)(iv) hereof); provided, however, that any such
redemption may be made without any payment of accrued dividends or interest on
outstanding shares of Series C Preferred Stock if the Company completes a
Qualified Public Offering on or before August 30, 1998.

                           (b) to effect redemptions of shares of Class A Common
Stock owned by any employee (other than one of the Management Stockholders) when
and as approved by the Board or required by law or by the terms of any
employment, stock grant or similar agreement with such employee upon such
employee's death, disability, termination of employment, or otherwise;

                           (c) from and after the time that there are, and
continue to be, more than sixty-six (66) physicians who hold, directly or
indirectly through their professional corporations, limited partner interests in
Medical Holdings Limited Partnership, a Maryland Limited Partnership (the "LP")
(or an option to purchase such an Interest) (each a "Physician Interest
Holder"), shares of Class B Common Stock issued by the Corporation to the LP
upon the termination of the status of any physician as a Physician Interest
Holder, until such time as the number of Physician Interest Holders is reduced
to sixty-six (66) or below, in the amount deemed necessary by the Board of
Directors at such time to ensure that the withdrawal of the Physician Interest
Holder increases the percentage ownership interests in the Corporation of all
other Stockholders of the Corporation to the same extent that the indirect
percentage ownership interests in the Corporation of the remaining Physician
Interest Holders are increased. Such redemption shall be for a redemption price,
if any, equal to the amount that the Corporation requires the LP to pay to such
withdrawing Physician Interest Holder upon his termination;

                           (d) under any other circumstances expressly
contemplated in the amended and restated Stockholders Agreement dated as of
September 4, 1996 among all of the Stockholders of the Corporation, including
any amendments thereto (the "Stockholders Agreement");

                           (e) under any circumstances expressly contemplated in
Section B.3(a), (b) or (c) hereof with respect to the Series A Preferred Stock;

                           (f) under any circumstances expressly contemplated in
Section C.3(a), (b) or (c) hereof with respect to the Series B Preferred Stock,
provided, 

                                       8

<PAGE>


however, that no such redemption, whether at the option of any holder
of the Series B Preferred Stock or at the option of the Corporation or
otherwise, shall be permitted or effected unless and until the Corporation shall
have elected to redeem all of the issued and outstanding shares of Series A
Preferred Stock prior to the effectiveness of such redemption of Series B
Preferred Stock and the Series A Redemption Price applicable to such redemption
shall have been paid in full or adequate provision therefor shall have been
made; and provided further, however, that nothing in this subsection shall
permit the Corporation to redeem the Series A Preferred Stock without consent of
the holders thereof under any circumstances not expressly permitted under
Section B.3 hereof.

                           (g) upon the exercise by a Series B Preferred
Stockholder of rights to require the Corporation to redeem its Series B
Preferred Stock under the circumstances expressly contemplated in Section 5.3(e)
of the Securities Purchase Agreement between the Corporation and Series B
Preferred Stockholder dated as of December 1, 1995 (the "Securities Purchase
Agreement"); provided, however, that no such redemption shall be permitted or
effected unless and until the Corporation shall have elected to redeem all of
the issued and outstanding shares of Series A Preferred Stock prior to the
effectiveness of such redemption of Series B Preferred Stock and the Series A
Redemption Price applicable to such redemption shall have been paid in full or
adequate provision therefore shall have been made; and provided further,
however, that nothing in this subsection shall permit the Corporation to redeem
the Series A Preferred Stock without consent of the holders thereof under any
circumstances not expressly permitted under Section B.3 hereof.

 . 

                           (h) under any circumstances expressly contemplated in
Section D.3 hereof with respect to the Series C Preferred Stock, provided,
however, that no such redemption shall be permitted or effected unless and until
the Corporation shall have elected to redeem all of the issued and outstanding
shares of Series A Preferred Stock and Series B Preferred Stock prior to the
effectiveness of such redemption of Series C Preferred Stock and the Series A
Redemption Price and Series B Redemption Price applicable to such redemptions
shall have been paid in full or adequate provision therefor shall have been
made; and provided further, however, that nothing in this subsection shall
permit the Corporation to redeem the Series A Preferred Stock or Series B
Preferred Stock without consent of the holders thereof under any circumstances
not expressly permitted hereunder.




                  B.       SERIES A PREFERRED STOCK.

                                     1.     VOTING RIGHTS.

                           (a) General Provisions. Holders of Series A Preferred
Stock shall be entitled to notice of each meeting of all of the Corporation's
stockholders, but shall

                                       9

<PAGE>


not be entitled to notice of special or other meetings of any class of
Common Stock or of Series B Preferred Stock or Series C Preferred Stock. The
holders of shares of Series A Preferred Stock shall vote together with the
holders of shares of Common Stock and Series B Preferred Stock and Series C
Preferred Stock on all matters submitted to a vote of stockholders and not as a
separate series or class, except as otherwise provided herein. Except as
otherwise provided herein, on all matters to be voted on by the Corporation's
stockholders, every holder of Series A Preferred Stock shall be entitled to
cast, in person or by proxy, that number of votes equal to the full number of
shares of Class C Common Stock into which such holder's Series A Preferred Stock
is then convertible.

                           (b) Series A Preferred Stock Directors. The holders
of shares of Series A Preferred Stock, voting as a single class, shall be
entitled to elect two (2) directors of the Corporation (the "Series A Preferred
Stock Directors"). Where the holders of Series A Preferred Stock vote as a
class, the affirmative vote of a majority of the shares of Series A Preferred
Stock represented in person or by proxy at a meeting at which a quorum of Series
A Preferred Stock is present shall be sufficient to approve any matter with
respect to which said holders are entitled to vote; provided, however, that the
affirmative vote of a plurality of all votes cast in person or by proxy by the
holders of Series A Preferred Stock shall be sufficient to elect a Series A
Preferred Stock Director. The holders of Series A Preferred Stock, at any
properly called annual or special meeting or upon a call of a special meeting of
holders of Series A Preferred Stock by holders of not less than twenty-five
percent (25%) of the shares of Series A Preferred Stock then outstanding, may
remove any Series A Preferred Stock Director at any time and from time to time,
voting as a single class, by the affirmative vote of eighty percent (80%) of all
votes entitled to be cast for the election of a Series A Preferred Stock
Director, and may elect a successor to fill any resulting vacancies for the
remainder of the term of such Series A Preferred Stock Director. If any Series A
Preferred Stock Director shall cease to be a director for any reason (including
death, resignation, removal or any other cause), the vacancy shall be filled by
a vote of the remaining Series A Preferred Stock Director (unless, with respect
to removal, the holders of Series A Preferred Stock have elected a successor
Series A Preferred Stock Director pursuant to the provisions hereof). If there
is no such remaining director, then upon a call of a special meeting of holders
of Series A Preferred Stock, by any such holder, the vacancy shall be filled by
the vote of the holders of Series A Preferred Stock, voting as a single class.

                           (c) Actions Requiring Series A Preferred Stock
Director Votes. Provided that no Series A Preferred Stockholder is, and has for
thirty (30) days been, in Default under or pursuant to and as defined in any
promissory note delivered to the Corporation by such Series A Preferred
Stockholder in partial consideration for the Corporation's issuance of Series A
Preferred Stock to such Stockholder, without the 

                                       10

<PAGE>


affirmative vote of each of the Series A Preferred Stock Directors, the
Corporation shall not:

                           (i) incur or permit any of its Subsidiaries (as
defined in Section B.1(d)(v)) to incur any Indebtedness (as defined in Section
B.1(d)(i)) as a result of which the outstanding Indebtedness of the Corporation
would on a consolidated basis exceed One Million Dollars ($1,000,000) in the
aggregate; other than (A) Indebtedness owing to the Investor named in that
certain Financing Transaction Agreement dated as of February 24, 1995, or any of
its affiliates; or (B) Indebtedness incurred under and pursuant to that certain
Credit Agreement and the related Credit Agreement Document as those terms are
defined in the Securities Purchase Agreement dated December 1, 1995 between the
Corporation and the Series B Stockholder (the "Securities Purchase Agreement");
or (C) Indebtedness not exceeding $20,000,000 incurred under and pursuant to one
or more revolving credit facilities guaranteed by the Series A Preferred
Stockholder and/or any other guarantors reasonably acceptable to the Series A
Preferred Stockholder; or

                           (ii) issue any shares of its capital stock with
liquidation or dividend rights senior to (or PARI PASSU with) the liquidation or
dividend rights of the Series A Preferred Stock; or

                           (iii) effect any amendment to these Amended and
Restated Articles of Incorporation or to the By-Laws of the Corporation that
adversely affects the holders of the Series A Preferred Stock or the Class C
Common Stock; or

                           (iv) effect any amendment to any of the Amended
Employment Agreements dated February 24, 1995 by and between the Corporation and
each of Stewart Gold ("Gold"), Scott Rifkin ("Rifkin") and Alan Kimmel
("Kimmel") (collectively, the "Management Employment Agreements"; and Gold,
Rifkin and Kimmel each being a "Management Stockholder" and collectively being
the "Management Stockholders"), or settle or compromise any claim or dispute of
the Corporation with respect thereto; or

                           (v) obligate the Corporation to do any of the
foregoing.

                           (d) Definitions. Except as otherwise expressly
provided, for purposes of these Amended and Restated Articles, the following
words shall have the meanings set forth:

                           (i) Unless excluded as set forth below,
"INDEBTEDNESS" shall mean (without duplication):

                           (A)  all indebtedness of the Corporation (as
                                calculated on a consolidated basis by including
                                all Indebtedness of each Subsidiary, whether or
                                not such inclusion is required under generally
                                accepted or other applicable accounting
                                principles) for borrowed money, the deferred
                                purchase price of property or services, all
                                obligations, contingent or otherwise, incurred
                                in connection with letters of credit, credit
                                facilities, acceptance or similar facilities,

                                respect to any calendar year. To the extent any

                           (e) Series A Preferred Stockholder Major Decisions.

                           (i) GENERAL PROVISIONS. Provided that no Series A
Preferred Stockholder is, and has for thirty (30) days been, in Default under or
pursuant to and as defined in any promissory note delivered to the Corporation
by such Series A Preferred Stockholder in partial consideration for the
Corporation's issuance of Series A Preferred Stock to such Stockholder, the
Corporation shall not take any of the following actions (each, a "Series A
Preferred Stockholder Major Decision") without first submitting such Series A
Preferred Stockholder Major Decision to a vote by the holders of Series A
Preferred Stock, voting separately as a class:

                           (A) the adoption of the Corporation's Business Plan
(as defined in Section B.1.(d)(iv) hereof) for any 12-month period or for
calendar years 1998 and 1999, or any amendment or periodic update to any
approved Business Plan;

                           (B) the issuance by the Corporation from time to time
after the date hereof of shares of its capital stock or options, warrants or
other rights to acquire any such shares, to employees of the Corporation,
directly or under any plan for the benefit of the foregoing or the issuance of
any such shares or options into an employee stock bonus pool in an amount which,
when aggregated with all other such issuances to employees of the Corporation,
exceeds ten percent (10%) of the fully diluted shares of capital stock of the
Corporation as of the date of such issuance; PROVIDED, HOWEVER, that shares of
Class A Common Stock (and options, warrants and rights to acquire shares of
Class A Common Stock) that have been, and will after the date hereof be, issued
to the three Management Stockholders and other executive employees of the
Corporation in amounts not to exceed twenty-five percent (25%) of the fully
diluted shares of capital stock of the Corporation as of the date hereof (the
"25% Management Stock Amount") shall NOT be counted toward such ten percent
(10%) limitation, such issuances to the Management Stockholders and other
executive employees being expressly authorized and consented to by the holders
of the Series A Preferred Stock;

                           (C) the cessation of the business of the Corporation;

                           (D) the issuance of shares of capital stock of the
Corporation with liquidation and dividend rights junior to those afforded to the
Series A Preferred Stock ("Series A Junior Stock") to any person or entity (a
"Series A Adverse Junior Stock Purchaser") which has legitimate business
interests that are materially adverse to the holders of Series A Preferred Stock
or any affiliate thereof ("Series A Adverse Junior Stock");

                           (E) any sale, transfer or other disposition by the
Corporation of all or any substantial portion of its assets whether by asset or
stock sale or otherwise;

                           (F) any conveyance, transfer or lease by the
Corporation of all or any substantial portion of its assets to any person, or to
any corporation, partnership or other entity;

                           (G) the consolidation or merger by the Corporation
with or into another corporation or entity, or the consolidation or merger of
another corporation or entity with or into the Corporation, where as a result of
such transactions the voting stockholders of the Corporation immediately prior
to such transaction would not hold sufficient voting stock in the surviving
entity immediately after such transaction to elect a controlling constituency of
the Board of Directors (or other governing body) in a transaction where the
Corporation is not the survivor;


                           (H) any Non-Qualified Public Offering;

                           (I) unless the Corporation has previously elected to
redeem all of the outstanding shares of Series A Preferred Stock and has paid or
adequately provided for payment of the Series A Redemption Price, any optional
redemption of Series B Preferred Stock pursuant to Section C.3(c) hereof; and/or

                           (J) any agreement by the Corporation to do any of the
foregoing.

                           (ii) CORPORATION ENTITLED TO TAKE CERTAIN ACTIONS
WITHOUT APPROVAL OF SERIES A PREFERRED STOCKHOLDERS. If a Series A Preferred
Stockholder Major Decision, other than an issuance of Series A Adverse Junior
Stock, is not approved by the holders of a majority of the then outstanding
shares of Series A Preferred Stock pursuant to the provisions of subparagraph
(i) hereof, then the Corporation shall nonetheless be entitled to take any of
such actions constituting such a Series A Preferred Stockholder Major Decision,
but shall provide written notice to that effect to the holders of Series A
Preferred Stock no later than ninety (90) days prior to the date such action is
to be effective and the holders of Series A Preferred Stock shall be entitled,
by delivery of a written notice to the Corporation at the principal office of
the Corporation not less than twenty-one (21) days prior to the date such action
is to be effective, to require the Corporation to redeem all, but not less than
all, of the then issued and outstanding shares of Series A Preferred Stock
pursuant to the provisions of Section B.3(a)(ii) hereof.

                           (iii) SERIES A ADVERSE JUNIOR STOCK; SPECIAL
PROVISIONS. If the Series A Preferred Stockholders do not approve an issuance of
Series A Junior 

                                       16

<PAGE>



Stock that they believe is Series A Adverse Junior Stock pursuant to the
provisions of subparagraph (i) hereof, then, upon the affirmative vote of a
majority of the directors of the Corporation other than the Series A Preferred
Directors, the Corporation shall be entitled, for a period of sixty (60) days
following the election of the holders of Series A Preferred Stock, not to
approve an issuance of such stock, and to require arbitration under the
expedited procedures set forth herein of whether the Series A Preferred
Stockholders or their affiliates have legitimate business interests that are
materially adverse to such Purchaser. Such arbitration shall be conducted by
three arbitrators, two of whom (the "Party Designated Arbitrators") shall be
selected by the parties, and the third of whom shall be a "Neutral Arbitrator"
selected by the Party Designated Arbitrators. The Corporation shall designate
its Party Designated Arbitrator in a written notice to the holders of Series A
Preferred Stock, and within five (5) days thereafter, such holders of Series A
Preferred Stock shall designate its Party Designated Arbitrator. Within five (5)
days thereafter, the two Party Designated Arbitrators shall agree upon and
appoint a Neutral Arbitrator, who shall be an attorney experienced in the health
care business. The only issue to be determined in the arbitration shall be
whether the proposed recipient of Series A Junior Stock has legitimate business
interests which are materially adverse to the holders of Series A Preferred
Stock. The arbitration shall be concluded within sixty (60) days of the date of
the Corporation's written notice. The determination of the arbitrators so
appointed shall be final and conclusive upon the parties. If the arbitrators
determine that the proposed purchaser is a Series A Adverse Junior Stock
Purchaser, then the Corporation may nonetheless proceed to issue such shares of
Series A Adverse Junior Stock to such purchaser, but shall provide written
notice to that effect to the holders of Series A Preferred Stock no later than
30 days prior to the date such issuance is consummated, and the holders of
Series A Preferred Stock shall thereupon become entitled to exercise their
rights to require the Corporation to redeem all, but not less than all, of the
issued and outstanding shares of Series A Preferred Stock pursuant to the
provisions of Section B.3.(a)(iii) hereof.

                           (f) Method of Approval. Whenever any action described
herein requires the action of holders of Series A Preferred Stock, such action
shall be deemed to have occurred upon the approval of holders of a majority of
the then issued and outstanding shares of Series A Preferred Stock at a duly
convened meeting of such stockholders or by their written consent in accordance
with the then applicable provisions of the MGCL, and the Corporation, in
undertaking any action with respect to such holders, shall be entitled to rely
upon a certificate signed by such holders to that effect.

                            2.      DIVIDENDS.

                           (a) Accrual of Dividends Before April 1, 2000.
Beginning as of February 24, 1995 and prior to April 1, 2000, cash dividends at
the rate of thirty-two and one half cents ($0.325) per share per annum shall
accrue on the Series A Preferred Stock (whether or not earned or declared or
payment is legally available therefor) in equal quarterly installments,
commencing on the first day of April, 1995, and continuing thereafter on the
first day of each month of July, October, January and April and shall accrue
interest at the rate of 6.5% (based upon a 365 day year) compounded quarterly on
all such unpaid dividend amounts.

                           (b) Payment of Dividends Before April 1, 2000.
Dividends and interest accrued on or with respect to accrual dates occurring
prior to April 1, 2000 shall be payable (either as part of a Redemption Price
(as defined below) or liquidation payment, or otherwise) prior to April 1, 2000
only upon (i) the liquidation of the Corporation as herein provided, or (ii) the
redemption or conversion of such share of Series A Preferred Stock, and if not
paid upon liquidation, redemption or conversion on or prior to April 1, 2000,
the amount of all such accrued dividends and interest payments shall from and
after April 1, 2000 become an unsecured obligation of the Corporation, bearing
interest at the rate, and being payable at the times, set forth with respect to
dividend payments in Section 2(c) below.

                           (c) Payment of Dividends on or After April 1, 2000.
Beginning on April 1, 2000, cash dividends, at the per annum rate of 100 basis
points over The Wall Street Journal Prime Rate as of the last business day prior
to April 1, 2000, shall accrue on the original issue price of all shares of
Series A Preferred Stock outstanding (whether or not earned or declared by the
Board), in equal quarterly installments on the first day of each month of April,
July, October and January. All such accrued dividends shall be declared by the
Board (if funds are at such time legally available therefor) and shall be
payable to each holder of Series A Preferred Stock on each such scheduled
quarterly date (as set forth above) if, at the time of payment funds for the
full payment of such quarterly dividend on all shares of Series A Preferred
Stock then outstanding are legally available therefor under the laws of the
State of Maryland as then in effect.

                           (d) Right of Set Off Against Dividends, Redemptions,
Liquidation, etc. The Corporation may set off against any amounts due and
payable to any holder of Series A Preferred Stock (including, but not limited
to, any dividend payments, Redemption Prices, liquidation payments or other
amounts) all or any part of any accrued but unpaid interest on any unpaid
principal amount owed to the Corporation by any holder, or prior holder, of
shares of Series A Preferred Stock pursuant to the terms of any promissory
note(s) delivered by such holder(s) to the Corporation for the issuance of such
shares of Series A Preferred Stock.

                           (e) Declaration Date. The date on which the Board
shall consider the payment of a particular quarterly dividend on the Series A
Preferred Stock pursuant to Section B.2.(c) hereof shall be any date that is
prior to the date on which such quarterly dividend would be payable if declared,
and which is not more than seventy-five (75) days prior to such quarterly
dividend payment date.

                           (f) Reduction of Capital. If at any time the Board
considers the payment of any quarterly dividend pursuant to Section B.2.(c)
hereof (i) funds for the full payment of such quarterly dividend are not then
legally available therefor under the laws of the State of Maryland as then in
effect as applied to the then effective capitalization of the Corporation, and
(ii) funds for the payment of such quarterly dividend would be legally available
if the stated capital accounts of the Corporation were reduced or capital
surplus was revalued, then, in such event, the Board shall reduce the stated
capital at least to the extent necessary to declare and pay such dividend or
cause a revaluation of capital surplus if such reduction of capital or valuation
of surplus would be permissible under the laws of the State of Maryland as then
in effect and unless the exercise of the Board's fiduciary duty prevents such
reduction.

                           (g) Limitation on other Dividends; Payments. So long
as any shares of Series A Preferred Stock remain outstanding, no dividends shall
be declared or paid upon, nor shall any dividend or other distribution be made
with respect to, any shares of any other class or series of stock or equity
interest of the Corporation or any Subsidiary without the consent of each of the
Series A Preferred Stock Directors and no shares of any class of stock or equity
interest of the Corporation or any Subsidiary other than the shares of Series A
Preferred Stock shall be redeemed, retired, purchased or otherwise acquired by
the Corporation, except purchases of the Corporation's interests in a Subsidiary
at the time of its organization. Notwithstanding the foregoing, the Corporation
may (i) effect Permitted Redemptions pursuant to Section A.5, and (ii) redeem
shares of capital stock of or equity interests in any wholly-owned Subsidiary.

                   3.      REDEMPTION.

                            (A)     OPTIONAL REDEMPTION BY HOLDERS.


                           (i) Permitted Time for Optional Redemption. At the
written request of any holder of Series A Preferred Stock, sent by such holder
to the Corporation at the principal office of the Corporation, during the
ninety-two (92) day period beginning on March 1, 2000, and ending on June 1,
2000, the Corporation shall, within ninety (90) days of the date of such request
(a "Series A Redemption Date") redeem for cash out of any funds legally
available therefor all, but not less than all, of

                                       19

<PAGE>


the then issued and outstanding shares of Series A Preferred Stock held by the
holders making such request, at an amount per share of Series A Preferred Stock
equal to the greater of (A) the then "fair market value" (as such term is
defined in Section 3(d)(viii) below) of such share, including, for purposes of
calculating such fair market value, the sum of all accumulated and unpaid
interest and dividends on such share of Series A Preferred Stock, whether or not
such dividends have been declared by the Corporation to the date such share is
actually redeemed and taking into account any right of set off of the
Corporation referred to in Section B.2(d) hereof, or (B) the sum of the issue
price of such share plus all accumulated and unpaid interest and dividends
thereon, whether or not such dividends have been declared by the Corporation
(subject to any right of set off of the Corporation referred to in Section
B.2(d) hereof), to the date such share is actually redeemed.

                           (ii) Permitted Redemption Resulting from Certain
Unapproved Series A Preferred Stockholder Major Decisions. If the Corporation
elects to take any action constituting a Series A Preferred Stockholder Major
Decision (other than the issuance of Series A Adverse Junior Stock) without the
approval of the holders of Series A Preferred Stock (as permitted pursuant to
the provisions of Section B.1.(e)(ii) hereof), the Corporation shall give notice
of such election to each holder of Series A Preferred Stock at least ninety (90)
days prior to the date such action is to be effective, and the holders of Series
A Preferred Stock shall be entitled, by delivery of a written notice to the
Corporation at the principal office of the Corporation not less than twenty-one
(21) days prior to the date such action is to be effective, to request the
Corporation to redeem, and the Corporation shall redeem out of any funds legally
available therefor, all (but not less than all) of the then issued and
outstanding shares of Series A Preferred Stock then held by the holders
requesting redemption, at an amount per share of Series A Preferred Stock equal
to the greater of (A) the then fair market value of such share (including, for
purposes of calculating such fair market value, the sum of all accumulated and
unpaid interest and dividends on such share of Series A Preferred Stock, whether
or not such dividends have been declared by the Corporation to the date such
share is actually redeemed and taking into account any right of set off of the
Corporation referred to in Section B.2(d) hereof), or (B) the sum of the issue
price of such share plus all accumulated and unpaid interest and dividends
thereon, whether or not such dividends have been declared by the Corporation
(subject to any right of set off of the Corporation referred to in Section
B.2(d) hereof), to the date such share is actually redeemed. To the extent that
net cash proceeds are received by the Corporation as the result of the taking of
such action constituting such a Series A Preferred Stockholder Major Decision,
other than the Series A Preferred Stockholder Major Decisions described in
Section B.3(a)(iii) below, which shall be treated as provided therein, (i) the
Corporation shall pay any redemption price in cash to the holders of Series A
Preferred Stock, such cash to be paid pro rata among the holders of Series A
Preferred Stock requesting such redemption (with such redemption being a
condition precedent to the Corporation's receipt of such net proceeds) upon the


                                       20

<PAGE>


occurrence of such action (a "Series A Redemption Date"). To the extent that
such net cash proceeds received by the Corporation as a result of taking such
Series A Preferred Stockholder Major Decision are insufficient to enable the
Corporation to make full payment in cash, the Corporation may pay the balance
due with respect to the redemption of such shares within 180 days of such
request.

                           (iii) Effect of Issuance of Series A Adverse Junior
Stock. If the Corporation elects to issue shares of Series A Adverse Junior
Stock after a determination by the arbitrators appointed pursuant to Section
B.1.(e)(iii) hereof that the purchaser thereof is a Series A Adverse Junior
Stock Purchaser, then the holders of Series A Preferred Stock shall be entitled,
by delivery of a written notice to the Corporation at the principal office of
the Corporation within ninety (90) days after the date of issuance of such
shares by the Corporation, to request the Corporation to redeem, and the
Corporation shall redeem, all but not less than all of the issued and
outstanding shares of Series A Preferred Stock held by holders requesting
redemption. Such redemption payment shall be made in cash prior to or
contemporaneously with such issuance if a request for redemption is made thirty
(30) or more days prior to the date specified for issuance by the Corporation in
its notice of issuance, and otherwise no sooner than 180 days after the date of
such request but in all events within one (1) year of such request (a "Series A
Redemption Date"). The redemption price shall in all events be an amount per
share of Series A Preferred Stock equal to the greater of (A) the purchase price
per share of Series A Adverse Junior Stock to be paid, on a fully diluted basis,
by the purchaser of such shares, or (B) the then fair market value of such share
of Series A Preferred Stock as calculated pursuant to subparagraph (i) hereof,
or (C) the product of (I) one and one half (1.5) times the sum of (II) the
liquidation preference of such shares, including therein all accumulated and
unpaid dividends and interest thereon (whether or not such dividends have been
declared by the Corporation but subject to any right of set off of the
Corporation pursuant to Section B.2(d) hereof) to the date such share is
actually redeemed. Interest shall accrue on the amount of the fair market value
per share at a rate of six and one half percent (6.5%) per annum from the date
such holders of Series A Preferred Stock deliver notice of their redemption
request to the Corporation until the full payment of all amounts payable with
respect to such redemption has been paid in cash by the Corporation.

                           (iv) Permitted Special Event Redemptions. Upon the
occurrence of a "Special Event Redemption," as set forth in Section 12.8 of that
certain Finance Transaction Agreement between the Corporation, the original
holder of the Series A Preferred Stock and others, dated as of February 24,
1995, the holders of the Series A Preferred Stock shall have a period of sixty
(60) days from the occurrence of such a Special Event Redemption to request the
Corporation to redeem, and the Corporation shall redeem, out of any funds
legally available therefor, all (but not less than all) of the then issued and
outstanding shares of Series A Preferred Stock, at an amount per share equal to
the sum of the issue price plus all accumulated and unpaid

                                       21

<PAGE>


interest and dividends thereon (subject to any right of set off of the
Corporation referred to in Section B.2(d) hereof), whether or not such dividends
have actually been declared. The Corporation shall be entitled to satisfy any
redemption obligations owing under this Section (b)(iv) by delivering to the
holders of Series A Preferred Stock a promissory note (or notes) with a term
equal to the longer of (A) 24 full months from the date of such request, or (B)
the number of full months remaining from the date of such request through
February 28, 1998 (collectively, the "Final Maturity Date"). Compound interest
shall accrue on any such note at the rate of 6 1/2 % per annum. The principal
amount of such note shall be amortized ratably on a 60 month basis. Accrued and
unpaid interest shall be payable, together with equal monthly installments of
principal, on the fifth day of each month following the issuance of such note,
with a final payment of all accrued and unpaid interest plus all remaining
unpaid principal due on the Final Maturity Date. Such note will be prepayable
without premium, will be subordinated to all then existing or thereafter created
Indebtedness, and will contain certain such customary default and other clauses
as are customary in promissory notes of such type and amount.

                           (B) MANDATORY REDEMPTION BY THE CORPORATION. Upon the
occurrence of any Non-Compliance (as defined in Section B.6), the Corporation
shall redeem all, but not less than all, of the shares of Series A Preferred
Stock then held by each holder at the redemption price as calculated pursuant to
the provisions of Section B.3.(a)(i), within ten (10) business days after the
occurrence of such Non-Compliance. Any such redemption shall not be in lieu of
or in any way limit any other rights which such holders may have (at law or in
equity) in connection with the event giving rise to their right of redemption.

                           (C) OPTIONAL REDEMPTION BY THE CORPORATION.

                           (i) Redemption in 2000. If the holders of Series A
Preferred Stock fail to request redemption of their shares of Series A Preferred
Stock within the ninety-two (92) day period provided in Section B.3(a)(i) hereof
for such optional redemption, and if such shares have not otherwise been
converted to shares of Class C Common Stock, then the Corporation may, out of
funds legally available therefor, upon at least thirty (30) days prior notice
delivered at any time after the expiration of such applicable period (a "Series
A Redemption Date"), redeem all, but not less than all, of the outstanding
shares of Series A Preferred Stock at an amount per share of Series A Preferred
Stock equal to the issue price of such share plus an amount equal to the amount
of all accumulated and unpaid dividends and interest on such share of Series A
Preferred Stock, whether or not such dividends have been declared by the
Corporation to the date such share is actually redeemed, minus any amount which
the Corporation is entitled to set off pursuant to the provisions of Section
B.2(d) hereof.

                           (ii) REDEMPTION UPON REDUCTION OF NOTE. If the
Corporation elects to defer receipt of all or any portion of any scheduled
payment of principal due and payable to the Corporation under any promissory
note made by any holder of Series A Preferred Stock in favor of and delivered to
the Corporation in consideration for the issuance by the Corporation of Series A
Preferred Stock to such holder (each a "Deferred Payment Amount"), then the
Corporation may, in its discretion and consistent with the provisions of any
such note, redeem a number of shares of Series A Preferred Stock from the maker
of such note determined by dividing the total amount of all then outstanding
Deferred Payment Amounts by five dollars ($5.00), at a redemption price of five
dollars ($5.00) for each such share, and set off all or any portion of such
Deferred Payment Amounts against any such Redemption Price (as defined below)
due hereunder. The Corporation shall give at least thirty (30) days notice to
the Series A Preferred Stockholders of any redemption pursuant to this
subsection (ii), which notice shall specify a redemption date (also a Series A
"Redemption Date").

                           (iii) REDEMPTION OF REMAINING SHARES OF SERIES A
PREFERRED STOCK UPON AUTOMATIC CONVERSION. To the extent that shares of Series A
Preferred Stock are not converted into shares of Class C Common Stock pursuant
to the provisions of Section B.4.(b) upon the occurrence of the events set forth
therein, the Corporation may redeem such remaining shares of Series A Preferred
Stock upon at least ten (10) days prior notice to the holders of Series A
Preferred Stock, which notice shall specify a redemption date (also a Series A
"Redemption Date"). The redemption price for such shares shall equal, and shall
be paid by, cancellation of the entire unpaid principal amount of the promissory
note delivered by the holder of such shares to the Corporation in partial
consideration for the issuance of such shares.

                            (D)     GENERAL PROVISIONS FOR REDEMPTIONS.

                           (i) Series A REDEMPTION PRICE. Each amount payable by
the Corporation pursuant to Section B.3(a) through (c) hereof respectively, is
referred to as the "Series A Redemption Price".

                           (ii) EFFECT OF REDEMPTION. Provision for payment of
the Series A Redemption Price for shares of Series A Preferred Stock having been
made by the Corporation, and for so long as there shall be no default in the
payment of deferred portions of the Redemption Price, then (A) the shares of
Series A Preferred Stock designated for redemption in any notice shall not be
entitled to any dividends accruing after the specified Redemption Date, and (B)
on such Redemption Date all rights of the respective holders of such shares, as
stockholders of the Corporation by reason of the ownership of such shares of
Series A Preferred Stock, shall cease, except the right to receive the
Redemption Price upon presentation and surrender of the respective certificates
representing such shares.


                                       23


                                       1
<PAGE>


                           (iii) DEFERRED PAYMENT FOR CERTAIN APPROVED SERIES A
PREFERRED STOCKHOLDER MAJOR DECISIONS. On any Series A Redemption Date resulting
from the failure of the holders of Series A Preferred Stock to approve (A) a
sale of all or substantially all of the assets of the Corporation whether by
asset or stock sale, or otherwise, for consideration other than all cash or (B)
the Corporation having conveyed, transferred or leased all or any substantial
portion of its assets to any person or entity, or (C) a consolidation or merger
referred to in Section B.1(e)(i)(G) above, the Corporation may, at its election,
in lieu of making payment in full in cash, prior to the consummation of any such
transaction, pay to each holder of shares of Series A Preferred Stock an amount
in cash equal to one-half (1/2) of the total Series A Redemption Price, and may
issue a promissory note of the Corporation in an amount equal to the balance of
such Series A Redemption Price; provided, however, that in the case of (A)
above, the Corporation shall be obligated to pay to the holders of the Series A
Preferred Stock an additional PRO RATA amount of cash (and shall be entitled to
reduce the principal amount of any note referred to in (iv) below), if and to
the extent it receives any cash as a result of such a transaction.


                           (iv) PROMISSORY NOTE. Any promissory note referred to
in subparagraph (iii), above, shall be payable in two (2) equal annual
installments, commencing on the one (1) year anniversary of the Series A
Redemption Date, of principal and interest and such interest shall accrue at the
then prime rate (the "Prime Rate") of the Corporation's primary banking
institution (or, if there be no such institution, the prime rate of interest as
published in the Wall Street Journal, from time to time) plus one hundred (100)
basis points. The obligations of the Corporation to make payment under such note
shall be secured by a perfected security interest in the Corporation's accounts
receivable (not more than 90 days' due at the date of perfection) with an
aggregate value of not less that 120% of all amounts payable under such note
from time to time, which recurring interest lien shall be subordinated only with
respect to payments and priority to any lien(s) granted to (A) any of the
Corporation's lending financial institutions, incurred in accordance with these
designations, or (B) a Series B Preferred Stockholder pursuant to a Final Credit
Enhancement Agreement dated December 1, 1995.

                           (v) RETIREMENT OF SHARES. Shares of Series A
Preferred Stock that have been redeemed, purchased or otherwise acquired by the
Corporation shall be retired and may not be reissued.

                           (vi) EFFECT OF LEGAL RESTRICTIONS ON PAYMENT. If the
Redemption Price for any such shares cannot be paid in full because the
Corporation is prohibited by law from making such payment, then those funds that
are legally available will be used to pay (ratably if necessary) accrued but
unpaid interest, then accrued but unpaid dividends, and then to redeem the
maximum possible number of shares of Series A Preferred Stock ratably among the
holders thereof determined by multiplying the total 

                                       24


                                       2
<PAGE>


number of shares of Series A Preferred Stock to be redeemed times a fraction,
the numerator of which shall be the total number of such shares then held by
each such holder and the denominator of which shall be the total number of such
shares then outstanding. The shares of Series A Preferred Stock not redeemed
shall remain outstanding and be entitled to all rights and preferences provided
herein; provided, however, at any time thereafter when additional funds of the
Corporation are legally available for the redemption of such shares of Series A
Preferred Stock, such funds will be used, at the end of the next succeeding
fiscal quarter, to redeem the balance of such shares, or such portion thereof
for which funds are then legally available. If fewer than the total number of
shares of Series A Preferred Stock represented by any certificate are redeemed,
a new certificate representing the number of unredeemed shares will be issued to
the holder thereof without cost to such holder within three business days after
surrender of the certificate representing the redeemed shares of Series A
Preferred Stock.

                           (vii) RESTRICTIONS ON CORPORATE ACTIONS. If the
Corporation for any reason fails to redeem any shares of Series A Preferred
Stock in accordance with this Section B.3 on or prior to the Redemption Date
specified herein, then, notwithstanding anything to the contrary contained in
these Articles of Incorporation, the Corporation may not incur any Indebtedness
(unless the proceeds of such incurrence of Indebtedness are used to make all
overdue redemption payments in respect of the Series A Preferred Stock,
including payments of accrued but unpaid dividends or interest) without the
prior written consent of the holders of the Series A Preferred Stock voting
separately as a class; provided, however, that, subject to the restriction set
forth in Section B.1(c)(i), if such restriction is then in force, the
Corporation may incur Indebtedness without the aforesaid approval if (A) the
proceeds of such borrowing are used to pay obligations of the Corporation
arising in the ordinary course of business as they become due and payable, or
otherwise to maintain the operations of the Corporation at the then current
level and not to expand the operation of the Corporation in any material
respect, whether through expansion or enhancement of, or addition, to the
Corporation's then current activities, facilities, equipment or other capital
assets, or otherwise, (B) the Corporation provides prior written notice of such
borrowing to all holders of Series A Preferred Stock, which notice shall include
a statement of the intended use of the proceeds of such borrowing, and (C)
promptly upon request therefor, the Corporation shall provide to any holder of
Series A Preferred Stock a certificate signed by the President and Chief
Financial Officer of the Corporation certifying as to the allocation and use of
the proceeds of any such borrowing.

                           (viii) APPRAISAL. Within fourteen (14) days of any
written request of any holder of shares of Series A Preferred Stock from time to
time, an appraiser or appraisers shall be jointly selected by the holders of
Series A Preferred Stock (the "Transferring Stockholder"), on the one hand, and
the Corporation on the other hand, and such jointly selected appraiser or
appraisers shall determine the fair market value 

                                       25


                                       3
<PAGE>


of the Series A Preferred Stock. The fair market value of the Series A Preferred
Stock shall be such amount as of such date as the appraisers determine, using
such methods as the appraisers appointed hereunder determine, in the exercise of
their sole discretion, is appropriate taking into account any liquidation,
conversion, preferences or other rights attendant to such class (which shall
specifically include the value of any Class C Common Stock into which such
shares of Series A Preferred Stock may at such time be converted). If the
Transferring Stockholder, on the one hand, and the Corporation on the other
hand, do not agree upon the selection of an appraiser or appraisers, within the
period therein stated, then, within seven (7) days after the expiration of the
fourteen (14) day period, the Transferring Stockholder shall appoint an
appraiser, and the Corporation shall appoint a second appraiser. The two (2)
appraisers so appointed shall appoint a third appraiser within seven (7) days
after both shall have been appointed. If either the Transferring Stockholder or
the Corporation shall fail to so appoint an appraiser, the appraiser duly
appointed by the other shall serve as the sole appraiser and such appraiser
shall determine the fair market value of the Series A Preferred Stock and such
determination shall be binding, final and conclusive on all parties. The said
appraiser(s) shall, within sixty (60) days after the last appointment thereof
determine the fair market value of the Series A Preferred Stock as otherwise
provided herein and the determination of such appraiser shall be determinative
of the fair market value of the Series A Preferred Stock and shall be binding,
final and conclusive on all parties. If the appraisers cannot agree on the fair
market value of the Series A Preferred Stock, within the time allotted, then
such fair market value shall be the median or the two appraisals closest in
value to each other. All expenses incurred in the appraisal process shall be
borne and paid equally by the Transferring Stockholder and the Corporation.

                           (ix) MULTIPLE HOLDERS OF SERIES A PREFERRED STOCK. If
the Series A Preferred Stock is at any time held by more than one person or
entity, the request for redemption pursuant to this Section B.3 by the holders
of at least fifty-one percent (51%) of the then issued and outstanding shares of
Series A Preferred Stock shall constitute the request for redemption by the
holders of all of the then issued and outstanding shares of Series A Preferred
Stock and all such holders of Series A Preferred Stock shall redeem their shares
of Series A Preferred Stock pursuant to this Section B.3 upon the receipt of
notice from holders of at least fifty-one percent (51%) of the then issued and
outstanding shares of Series A Preferred Stock.

                   4.      CONVERSION RIGHTS.

                            (A)     OPTIONAL CONVERSION BY HOLDER.

                           (i) General Provisions. All, but not less than all,
of the issued and outstanding shares of Series A Preferred Stock shall be
convertible, without the payment of any additional consideration, into shares of
Class C Common Stock, at the 


                                       26


                                       4
<PAGE>


option of the holders of the shares of Series A Preferred Stock, at any time
prior to 5:00 P.M. (EST) on February 24, 2000; provided, however, that issued
and outstanding shares of Series A Preferred Stock may not be converted into
shares of Class C Common Stock as otherwise permitted herein if, at the time of
such requested conversion, the Corporation has not received cash in full payment
for all shares of Series A Preferred Stock outstanding at such time (including
payment in full of all amounts of principal and interest under any note given in
partial consideration for such shares, but less any accrued but unpaid dividends
with respect thereto); and provided, further, however, that if such conversion
occurs at any time during the 60 day period referred to in Section 3(a)(ii)
(other than as the result of the adoption of a Business Plan as set forth in
Section 1(e)(i)(A) (above) or pursuant to Section 3(a)(iii) above, after the
Corporation elects to take any action constituting a Series A Preferred
Stockholder Major Decision without the approval of the holders of the Series A
Preferred Stock, such conversion shall not be deemed to be an "optional
conversion" governed by the provisions of this Section 4(a), but shall be
governed by the provisions relating to "Automatic Conversions" set forth in
Section 4(b) below. Each such share of Series A Preferred Stock shall be
convertible at such time into one fully-paid and nonassessable share of Class C
Common Stock, subject to adjustment as provided in Section B.4.(e) below (the
"Series A Conversion Rate"). The holders of shares of Series A Preferred Stock
requesting conversion of shares into shares of Class C Common Stock shall send a
written notice to the Corporation, at the principal office of the Corporation,
requesting such conversion. The holders shall, as soon thereafter as
practicable, deliver the certificates therefor, duly endorsed for transfer, at
the principal office of the Corporation or any transfer agent for the Series A
Preferred Stock. The Corporation shall, as soon as practicable thereafter, issue
and deliver to the holders a certificate or certificates for the number of such
shares of Class C Common Stock to which the holders shall be entitled, a check
payable to the holders in the amount of any cash in lieu of issuance of any
fractional share, and the amount of any cumulative dividends and interest
accrued but unpaid on such shares. The conversion shall be deemed to have been
made immediately prior to the close of business on the date of receipt of the
notice. The persons entitled to receive the shares of Class C Common Stock
issuable upon such conversion shall be treated for all purposes as the record
holder or holders of such shares of Class C Common Stock on such date, and the
shares of Series A Preferred Stock converted shall immediately be canceled and
may not be reissued.

                           (ii) Multiple Holders of Series A Preferred Stock. If
the Series A Preferred Stock is at any time held by more than one person or
entity, the request for conversion pursuant to this Section B.4 by the holders
of at least fifty-one percent (51%) of the then issued and outstanding shares of
Series A Preferred Stock shall constitute the request for conversion by the
holders of all of the then issued and outstanding shares of Series A Preferred
Stock and all such holders of Series A Preferred Stock shall convert their
shares of Series A Preferred Stock pursuant to this 

                                       27


<PAGE>


Section B.4 upon the receipt of notice from holders of at least fifty-one
percent (51%) of the then issued and outstanding shares of Series A Preferred
Stock.

                           (B) AUTOMATIC CONVERSION. If the holders of Series A
Preferred Stock have not earlier exercised their rights to require the
Corporation to redeem their shares of Series A Preferred Stock pursuant to the
provisions of Section B.3.(a) hereof, such number of outstanding shares of
Preferred Stock equal to the product of the number of outstanding shares of
Series A Preferred Stock multiplied by a fraction, the numerator of which shall
be the total amount of cash paid to the Corporation by such holders to purchase
shares of Series A Preferred Stock (but not including the payment of any
interest to the Corporation) and the denominator of which shall be $5 million,
shall, together with all other then outstanding shares of the Corporation's
preferred stock or other capital stock with rights to convert into shares of
Common Stock, be converted into fully-paid and nonassessable shares of Class C
Common Stock at the Series A Conversion Rate upon the earlier to occur of the
closing or other consummation of (i) any Qualified Public Offering, (ii) any
Non-Qualified Public Offering, (iii) any combination, consolidation or merger
where the Corporation is not the survivor, (iv) any sale, exchange or other
disposition of all or substantially all of the Corporation's assets, whether by
asset or stock sale or otherwise, or (v) any election by the holders of Series A
Preferred Stock to effect an "Optional Conversion" during any period during
which the holders of the Series A Preferred Stock may cause the Corporation to
redeem shares of their Series A Preferred Stock pursuant to the provisions of
Section 3(a)(ii) or 3(a)(iii), above. In the case of the occurrence of any of
(i) through (v) above, all remaining shares of Series A Preferred Stock which
have not been converted into shares of Class C Common Stock, shall be subject to
mandatory redemption by the Corporation pursuant to the provisions of Section
B.3.(iii) hereof. Shares of Class C Common Stock received pursuant to this
Section 4.(b) shall be subject to the provisions of Article IV, Section A.4 in
the event of a Qualified Public Offering or Non-Qualified Public Offering, and
shall thereupon immediately be reclassified as shares of Class A Common Stock.
At least twenty (20) days prior written notice of the date fixed and place
designated for conversion shall be sent by first class mail, postage prepaid, to
the address of each holder of shares of Series A Preferred Stock as shown in the
records of the Corporation. On or before the date fixed for conversion, each
holder of shares of Series A Preferred Stock shall surrender the certificates
representing such shares to the Corporation at the place designated in such
notice and shall thereafter receive certificates for the number of full shares
of Common Stock to which such holder is entitled. Until such time as holders of
certificates theretofore representing shares of Series A Preferred Stock have
surrendered them for exchange as provided herein, no dividends shall be paid
with respect to any shares represented by such certificates and no payment for
fractional shares shall be made.

                           (c) NO FRACTIONAL SHARES. No fractional shares of
Common Stock shall be issued upon conversion of shares of Series A Preferred
Stock. In lieu of any 


                                       28


<PAGE>


fractional share, the Corporation shall pay a cash adjustment in respect of such
fractional interest equal to the fair market value of such fractional interest
as determined by the Board.

                           (d) PAYMENT; DIVIDENDS. At the time of the conversion
of any shares of Series A Preferred Stock, whether mandatory or optional, the
Corporation shall pay to the holder of such shares of Series A Preferred Stock
the sum of all interest and cumulative dividends accrued but unpaid with respect
to such shares, whether or not such dividends shall have been declared by the
Corporation to the date of conversion (subject to the Corporation's right of set
off referred to in Section B.2(d) hereof).

                           (e) ADJUSTMENTS; ANTIDILUTION. The number of shares
of Class C Common Stock issuable upon the conversion of the Series A Preferred
Stock shall be subject to adjustment from time to time upon the happening of
certain events as follows:

                           (i) DIVIDENDS, SPLITS. If the Corporation declares a
dividend payable in its shares of its Common Stock, splits any of its Common
Stock or combines any of its outstanding shares of Common Stock into a smaller
number, then the number of fully-paid and nonassessable shares of Class C Common
Stock into which each share of Series A Preferred Stock may be converted shall
forthwith be adjusted by multiplying one (1) by a fraction (A) the numerator of
which shall be the total number of outstanding shares of Common Stock
immediately after such dividend, stock split or combination, and (B) the
denominator of which shall be the total number of outstanding shares of Common
Stock immediately prior to such dividend, stock split or combination.

                           (ii) REORGANIZATION, RECLASSIFICATION. In the event
of a reorganization, share exchange, or reclassification, other than a change in
par value, or from par value to no par value, or from no par value to par value
or a transaction described in subsection (iii) or (iv) below, each share of
Series A Preferred Stock shall, after such reorganization, share exchange or
reclassification, be convertible into the kind and number of shares of stock or
other securities or property of the Corporation to which the holder of Series A
Preferred Stock would have been entitled if the holder had held the Class C
Common Stock issuable upon conversion of its Series A Preferred Stock
immediately prior to such reorganization, share exchange, or reclassification,
or to which the Series A Preferred Stock is actually entitled, but not both.

                           (iii) CONSOLIDATION, MERGER, SALE OF ASSETS. In the
event of a merger or consolidation or sale, exchange or other disposition of
all, or substantially all of the Corporation's assets, to which the Corporation
is a party, each share of Series A Preferred Stock shall, after such merger or
consolidation, be convertible into the kind and number of shares of stock and/or
other securities, cash or other property to which the holder of such share of
Series A Preferred Stock would have been entitled if the holder had held the
Class C Common Stock issuable upon conversion of its shares of 

                                       29


<PAGE>


Series A Preferred Stock immediately prior to such consolidation or merger or
sale of assets, or to which the Series A Preferred Stock is actually entitled,
but not both.

                           (iv) CERTAIN ISSUANCES OF ADDITIONAL SHARES OF COMMON
STOCK. If the Corporation shall issue any additional shares of Common Stock --
other than securities to be issued (i) to the public pursuant to any Qualified
Public Offering or Non-Qualified Public Offering, (ii) to officers, directors,
or employees of the Corporation as part of a stock option plan, restricted stock
plan, employee stock purchase plan, employment agreement, or other employee
stock plan or agreement, implemented by the Board, provided that the aggregate
numbers of such shares issued shall not exceed ten percent (10%) of the fully
diluted capital stock of the Corporation calculated as of the time of the
issuance, (iii) to Management Stockholders and other executive employees of the
Corporation, of an amount of Class A Common Stock not in excess of the 25%
Management Stock Amount, (iv) upon conversion of any shares of the Series A
Preferred Stock, the Series B Preferred Stock, the Series C Preferred Stock or
the exercise of that certain Stock Warrant granted by the Company to the Series
B Preferred Stockholder, of even date herewith, to purchase 88,889 shares of
Class A Common Stock at an exercise price that is equal to or exceeds the
"conversion price" including any adjustment thereof, (v) upon the exercise of
that certain Stock Warrant granted by the Company to John R. Dwyer, Jr., Stephen
X. Hamilton and D. Andrew Hamilton December 1, 1995 to purchase in the aggregate
24,000 shares of Class A Common Stock, or (vi) to the LP pursuant to Article XIV
of the Practice Participation Agreement in respect of the issuance of Medical

purchase such Interests) from and after the time that more than sixty-six (66)
but less than one hundred (100) physicians hold such Limited Partner Interests
(or options to acquire such Interests) directly or indirectly through their
professional corporations -- for a consideration per share of Common Stock less
than the "conversion price", as adjusted or as previously adjusted, in effect on
the date immediately prior to such issuance, then and in such event, such
conversion price shall be adjusted, concurrently with such issuance, to a price
equal to the quotient obtained by DIVIDING:

                                    (1) an amount equal to (x) the sum of (A)
                  the total number of shares of Common Stock outstanding
                  immediately prior to such issuance or sale, plus (B) the total
                  number of shares of Common Stock issuable upon exercise of all
                  options, warrants and other rights convertible or exchangeable
                  for, or evidencing the right to purchase shares of, Common
                  Stock outstanding immediately prior to such issuance or sale,
                  multiplied by the (C) conversion price in effect immediately
                  prior to such issuance or sale, plus (y) the consideration, if
                  any, received or deemed to be received by the Corporation upon
                  such issuance or sale; BY


                                       30


<PAGE>


                                    (2) the sum of (A) total number of shares of
                  Common Stock outstanding immediately after such issuance or
                  sale, plus (B) the total number of shares of Common Stock
                  issuable upon exercise of all options, warrants and other
                  rights convertible or exchangeable for, or evidencing the
                  right to purchase shares of, Common Stock outstanding
                  immediately after such issuance or sale.

For purposes of this Section B.4, the conversion price shall initially be $5.00
per share.

No adjustment of the conversion price shall be made under this Section
B.4.(e)(iv) upon the issuance of any additional shares of Common Stock that are
issued pursuant to the exercise of any warrants, options or other subscription
or purchase rights or pursuant to the exercise of any conversion or exchange
rights in any convertible securities if any such adjustments shall previously
have been made upon the issuance of any such warrants, options or other rights
or upon the issuance of any convertible securities (or upon the issuance of any
warrants, options or any rights therefor) pursuant to Sections 4(v) or 4(vi)
hereof.

                           (v) ISSUANCE OF WARRANTS, OPTIONS OR OTHER RIGHTS. If
the Corporation at any time shall issue any warrants, options or other rights to
subscribe for or purchase any additional shares of Common Stock and the price
per share for which additional shares of Common Stock may at any time thereafter
be issuable pursuant to such warrants, options or other rights shall be less
than the conversion price per share in effect immediately prior to such
issuance, then such issue shall be deemed an issuance (as of the date of issue
of such warrants, options or other rights) of the total maximum number of shares
of Common Stock issuable pursuant to such warrants, options or other rights, and
the conversion price shall thereupon be adjusted as provided in Section
B.4.(e)(iv) hereof on the basis that the aggregate consideration for the
additional shares of Common Stock issuable pursuant to such warrants, options or
other rights, plus the minimum consideration to be received by the Corporation
for the issuance of additional shares of Common Stock pursuant to such warrants,
options, or other rights shall be deemed to be the consideration received by the
Corporation for the issuance of such warrants, options, or other rights.

                           (vi) CERTAIN ISSUANCES OF CONVERTIBLE SECURITIES. In
case the Corporation shall issue any securities convertible into Common Stock
and the consideration per share for which such additional shares of Common Stock
may at any time thereafter be issuable pursuant to the terms of such convertible
securities shall be less than the conversion price per share in effect
immediately prior to such issuance, then upon such issuance of such securities
the conversion price shall be adjusted as provided in Section B.4.(e)(iv) hereof
on the basis that (i) the maximum number of additional shares of Common Stock
necessary to effect the conversion or exchange of all such convertible
securities shall be deemed to have been issued as of the date of 


                                       31


<PAGE>


issuance of such convertible securities, and (ii) the aggregate consideration
for such maximum number of additional shares of Common Stock plus the minimum
consideration received by the Corporation for the issuance of such additional
shares of Common Stock pursuant to the terms of such convertible securities
shall be deemed to be the consideration received by the Corporation for the
issuance of such convertible securities. No adjustment of the conversion price
shall be made under this subsection upon the issuance of any convertible
securities which are issued pursuant to the exercise of any warrants, options or
other subscription or purchase rights therefor, if any such adjustment shall
previously have been made upon the issuance of such warrants, options or other
rights pursuant to Section B.4.(e)(v) hereof.

                           (vii) ADJUSTMENT OF SERIES A CONVERSION RATE. Upon
each adjustment of the conversion price under the provisions of this Section
B.4.(e), the Series A Conversion Rate shall be adjusted to an amount determined
by dividing $5.00 by such adjusted conversion price. For example, if, as a
result of any of the foregoing, the conversion price was reduced to $4.00, each
share of Series A Preferred Stock would then be convertible into 1.25 shares of
Class C Common Stock.

                           (viii) OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS
UNDER THIS SECTION. The following provisions will be applicable to the making of
adjustments in conversion prices hereinabove provided in this Section B.4.(e):

                           (1) COMPUTATION OF CONSIDERATION. To the extent that
any additional shares of Common Stock or any convertible securities or any
warrants, options or other rights to subscribe for or purchase any additional
shares of Common Stock or any convertible securities shall be issued for cash
consideration, the consideration received by the Corporation therefor shall be
deemed to be the amount of the cash received by the Corporation therefor, or, if
such additional shares of Common Stock or convertible securities are offered by
the Corporation for subscription, the subscription price. To the extent that
such issuance shall be for a consideration other than cash, then the amount of
such consideration shall be deemed to be the fair value of such consideration at
the time of such issuance as determined in good faith by the Corporation's Board
after receipt of a fairness opinion, appraisal or similar independent third
party advice determined by a person or entity jointly selected by the Series A
Preferred Directors, the Series B Preferred Directors, the Series C Preferred
Directors and the other directors pursuant to procedures substantially similar
to those set forth in Section 6 of the Stockholders Agreement. The consideration
for any additional shares of Common Stock issuable pursuant to any warrants,
options or other rights to subscribe for or purchase the same shall be the
consideration received by the Corporation for issuing such warrants, options or
other rights, plus the additional consideration payable to the Corporation upon
the exercise of such warrants, options or other rights. The consideration for
any additional shares of Common Stock issuable pursuant to the terms of any
convertible securities shall be the consideration paid or 


                                       32


<PAGE>


payable to the Corporation in respect of the subscription for or purchase of
such convertible securities, plus the additional consideration, if any, payable
to the Corporation upon the exercise of the right of conversion or exchange in
such convertible securities. In case of the issuance at any time of any
additional shares of Common Stock or convertible securities in payment or
satisfaction of any dividend upon any class of stock preferred as to dividends
in a fixed amount, the Corporation shall be deemed to have received for such
additional shares of Common Stock or convertible securities a consideration
equal to the amount of such dividend so paid or satisfied.

                           (2) READJUSTMENT OF CONVERSION PRICE. Upon the
expiration of the right to convert or exchange any convertible securities, or
upon the expiration of any rights, options or warrants, without conversion,
exchange or exercise, the issuance of which convertible securities, rights,
options or warrants effected an adjustment in the conversion price, such
conversion price shall forthwith be readjusted and thereafter be the price which
it would have been (but reflecting any other adjustments in the conversion price
made pursuant to the provisions of this Section B.4.(e) after the issuance of
such convertible securities, rights, options or warrants) had the adjustment of
the conversion price made upon the issuance or sale of such convertible
securities or issuance of rights, options or warrants been made on the basis of
the issuance only of the number of additional shares of Common Stock actually
issued upon conversion or exchange of such convertible securities, or upon the
exercise of such rights, options or warrants, and thereupon only the number of
additional shares of Common Stock actually so issued, if any, shall be deemed to
have been issued and only the consideration actually received by the Corporation
(computed as set forth in subsection B.4.(e)(viii)(1) hereof) shall be deemed to
have been received by the Corporation. If the purchase price provided for in any
such rights, options or warrants, or the additional consideration (if any)
payable upon the conversion or exchange of any convertible securities, or the
rate at which any convertible securities are convertible into or exchangeable
for shares of Common Stock changes at any time (other than under or by reason of
provisions designed to protect against dilution), the conversion price in effect
at the time of the change shall be adjusted to the conversion price that would
have been in effect at such time had such rights, options, warrants or
convertible securities still outstanding provided for such changed purchase
price, additional consideration or conversion rate, as the case may be, at the
time initially granted, issued or sold.

                           (3) OTHER ACTION AFFECTING COMMON STOCK. If the
Corporation shall take any action affecting the outstanding number of shares of
Common Stock, other than an action described in any of the foregoing subsections
4(e)(i) to (vii) hereof, inclusive, which in the opinion of the Corporation's
Board would have a materially adverse effect upon the rights of the holders of
the Series A Preferred Stock, the conversion price shall be adjusted in such
manner and at such time as the Board may determine to be equitable in the
circumstances.


                                       33


<PAGE>


                           (ix) NOTICES OF ADJUSTMENTS. Whenever the conversion
rate and conversion price is adjusted as herein provided, an officer of the
Corporation shall compute the adjusted conversion rate and conversion price in
accordance with the foregoing provisions and shall prepare a written instrument
setting forth such adjusted conversion rate and conversion price and showing in
detail the facts upon which such adjustment is based, and such written
instrument shall promptly be delivered to the record holders of the Series A
Preferred Stock, who shall approve such conversion rates and prices within 30
days of receipt. If holders of Series A Preferred Stock do not object in writing
during such 30 day period, they shall be deemed to have approved such conversion
rates and prices for all purposes hereof.

                           (f)RESERVATION OF SHARES. The Board shall at all
times reserve and keep available, out of its authorized but unissued shares of
Class C Common Stock, solely for the purpose of effecting the conversion of the
shares of Series A Preferred Stock, the full number of shares of Class C Common
Stock deliverable by the Corporation upon the conversion of all shares of Series
A Preferred Stock from time to time outstanding and otherwise issuable under
rights granted from the Corporation then existing.

                           (g)NO IMPLIED MODIFICATION OF TERMS. The provisions
of this Section B.4. shall not give, or be deemed to give, the Corporation the
power or authority to issue any shares of its capital stock or other securities
or to take any other action that it is expressly prohibited from issuing by
another provision hereof.

                   5.      LIQUIDATION RIGHTS.

                           (a) Upon any liquidation, dissolution or winding up
of the affairs of the Corporation, whether voluntary or involuntary, the holders
of shares of the Series A Preferred Stock shall be entitled to receive out of
the assets of the Corporation available for distribution to stockholders, before
any distribution or payment shall be made in respect of the holders of shares of
Common Stock or any other class or series of stock ranking junior to the Series
A Preferred Stock, a liquidating distribution in an amount equal to the greater
of (i) the sum of the "fair market value" per share of Series A Preferred Stock,
which shall include an amount per share equal to all cumulative dividends and
interest accrued but unpaid thereon, whether or not such dividends and interest
shall have been declared by the Corporation, to the date fixed for such
distribution or payment (but subject to reduction to the extent the Corporation
exercises its right of set off referred to in Section B.2(d) hereof); or (ii)
the sum of the original purchase price per share of Series A Preferred Stock
plus an amount equal to all cumulative dividends and interest accrued but unpaid
thereon to the date fixed for such distribution or payment; provided, however,
in either such event the amount of cash payable by the Corporation shall not
exceed the amount of cash paid to the 

                                       34


<PAGE>


Corporation by all holders of such shares with respect to the purchase of such
shares, including the payment of any interest with respect thereto, through and
including the date of liquidation. The holders of shares of Series A Preferred
Stock shall not be entitled to receive any additional distributive amounts upon
such liquidation, dissolution or winding up of the affairs of the Corporation
resulting in any distribution of assets to stockholders.

                           (b) If, upon any such liquidation, dissolution or
winding up of the affairs of the Corporation, the assets of the Corporation to
stockholders shall be insufficient to permit the payment in full to the holders
of Series A Preferred Stock of the amounts to which they are entitled, then all
of such available assets shall be distributed to the holders of shares of Series
A Preferred Stock ratably in proportion to the liquidation payment otherwise due
under Section B.5.(a) to each such holder and no amounts shall be distributed in
respect of any other share of capital stock of the Corporation until all amounts
distributable to holders of Series A Preferred Stock have been distributed.

                           (c) The purchase or redemption by the Corporation of
stock of any class, in any manner permitted by law, shall not for the purpose of
this Section B.5. be regarded as a liquidation, dissolution or winding up of the
Corporation. Neither the consolidation nor merger of the Corporation with or
into any other corporation or corporations, nor the sale or transfer by the
Corporation of all or any part of its assets shall be deemed to be a
liquidation, dissolution or winding up of the Corporation for the purpose of
this Section B.5.

                           (d) At least thirty (30) days prior written notice of
any such liquidation, dissolution or winding up of the affairs of the
Corporation stating a payment date, the amount of the liquidation payments and
the place where said liquidation payments shall be payable, shall be sent by
first class mail, postage prepaid, to each holder of Series A Preferred Stock at
his address as shown on the records of the Corporation.

                   6.      EVENTS OF NON-COMPLIANCE; NON-COMPLIANCE.

                           (a) DEFINITION. "Event of Non-Compliance" shall mean,
with respect to the Corporation, the occurrence of any of the events,
occurrences or circumstances listed below; provided, however, that any such
event, occurrence or circumstance shall constitute "Non-Compliance" if, and only
if, (i) in the case of any event, occurrence or circumstance involving the
non-payment of moneys (other than dividend and accrued interest payments due and
payable to the holders of Series A Preferred Stock), within thirty (30) calendar
days following written notice of such non-payment, such moneys have not been
paid by or on behalf of the Corporation; and (ii) in the case of any event,
occurrence or circumstance not involving the non-payment of moneys, substantial
efforts have not been commenced by or on behalf of the Corporation to cure such

                                       35


<PAGE>


event, occurrence, or circumstance within a reasonable time after notice thereof
(but in no event later than 30 days), and having been so commenced, there is a
failure within a reasonable time to prosecute to completion with diligence and
continuity the curing of such event, occurrence or circumstances, or a period of
more than 90 days has occurred without such cure being completed to the
satisfaction of the holders of the Series A Preferred Stockholders; provided,
further, however, that, for purposes of (i) and (ii) above the occurrence of any
of the events, occurrences or circumstances described in subparagraphs (5), (6)
(7), (8), (9) or (10), below shall constitute Non-Compliance immediately upon
its occurrence or upon the happening of such event or circumstances, without any
requirement of notice or passage of time except as specifically set forth in
such item:

                           (4) beginning on April 1, 2000, whenever dividends
accruing after such date on the Series A Preferred Stock shall be in arrears in
an aggregate amount equal to at least 4 quarterly dividends thereon;

                           (5) institution by the Corporation of proceedings of
any nature under any laws or regulations, whether now existing or subsequently

relief as debtor;

                           (6) a general assignment by the Corporation for the
benefit of creditors;

not dismissed, stayed or discharged within a period of ninety (90) calendar days
after the filing thereto;

                           (9) the appointment of a receiving, custodian,

                           (11) attachment, execution or other judicial seizure
of all or any substantial part of the Corporation's assets, such attachment,
execution or seizure in any case remaining undismissed or undischarged for a
period of fifteen (15) calendar days after the levy thereof; provided, however,
that said attachment, execution or seizure shall not constitute an Event of
Non-Compliance hereunder if the Corporation posts a bond sufficient in amount to
satisfy or secure the payment of such claim or judgment within sixty (60)
calendar days after the levy thereof and the Corporation's assets are thereby
released from the lien of such attachment;

                           (12) one or more judgments or decrees is entered
against the Corporation or any of its Subsidiaries involving in the aggregate a

$300,000 with respect to 1997; $400,000 with respect to 1998; and $500,000 with
respect to each year thereafter or (B) ten percent (10%) of the net operating

                  C.       SERIES B PREFERRED STOCK.

                                     1.     VOTING RIGHTS.

                           (a) General Provisions. Holders of Series B Preferred
Stock shall be entitled to notice of each meeting of all of the Corporation's
stockholders, but shall not be entitled to notice of special or other meetings
of any class of Common Stock or of Series A Preferred Stock or Series C
Preferred Stock. The holders of shares of Series B Preferred Stock shall vote
together with the holders of shares of Common Stock and Series A Preferred Stock
and Series C Preferred Stock on all matters submitted to a vote of stockholders
and not as a separate series or class, except as otherwise provided herein.
Except as otherwise provided herein, on all matters to be voted on by the
Corporation's stockholders, every holder of Series B Preferred Stock shall be
entitled to cast, in person or by proxy, that number of votes equal to the full
number of shares of Class C Common Stock into which such holder's Series B
Preferred Stock is then convertible.

                           (b) Series B Preferred Stock Directors. The holders
of shares of Series B Preferred Stock, voting as a single class, shall be
entitled to elect two (2) directors of the Corporation (the "Series B Preferred
Stock Directors"). Where the holders of Series B Preferred Stock vote as a
class, the affirmative vote of a majority of the shares of Series B Preferred
Stock represented in person or by proxy at a meeting at which a quorum of Series
B Preferred Stock is present shall be sufficient to approve any matter with
respect to which said holders are entitled to vote; provided, however, that the
affirmative vote of a plurality of all votes cast in person or by proxy by the
holders of Series B Preferred Stock shall be sufficient to elect a Series B
Preferred Stock Director. The holders of Series B Preferred Stock, at any annual
meeting or upon a call of a special meeting of holders of Series B Preferred
Stock by holders of not less than twenty-five percent (25%) of the shares of
Series B Preferred Stock then outstanding, may remove any Series B Preferred
Stock Director at any time and from time to time, voting as a single class, by
the affirmative vote of eighty percent (80%) of all votes entitled to be cast
for the election of a Series B Preferred Stock Director, and may elect a
successor to fill any resulting vacancies for the remainder of the term of such
Series B Preferred Stock Director. If any Series B Preferred Stock Director
shall cease to be a director for any reason (including death, resignation,
removal or any other cause), the vacancy shall be filled by a vote of the
remaining Series B Preferred Stock Director (unless, with respect to removal,
the holders of Series B Preferred Stock have elected a successor Series B
Preferred Stock Director pursuant to the provisions hereof). If there is no such
remaining director, then upon a call of a special meeting of holders of Series B
Preferred Stock, by any such holder, the vacancy shall be filled by the vote of
the holders of Series B Preferred Stock, voting as a single class.


                                       39


<PAGE>


                           (c) Actions Requiring Series B Preferred Stock
Director Votes. Without the affirmative vote of each of the Series B Preferred
Stock Directors, the Corporation shall not:

                           (i) incur or permit any of its Subsidiaries (as
defined in Section B.1(d)(v)) to incur any Indebtedness (as defined in Section
B.1(d)(i)) as a result of which the outstanding Indebtedness of the Corporation
would on a consolidated basis exceed One Million Dollars ($1,000,000) in the
aggregate; other than (A) Indebtedness owing to the Investor named in that
certain Financing Transaction Agreement dated as of February 24, 1995, or any of
its affiliates, or (B) Indebtedness incurred under and pursuant to that certain
Credit Agreement and the related Credit Agreement Documents as defined in the
Securities Purchase Agreement, or (C) Indebtedness not exceeding $20,000,000
incurred under and pursuant to one or more revolving credit facilities

                           (iii) effect any amendment to these Amended and
Restated Articles of Incorporation or to the By-Laws of the Corporation that
adversely affects the holders of the Series B Preferred Stock or the Class C
Common Stock; or

                           (iv) effect any amendment to any of the Amended

                           (i) GENERAL PROVISIONS. The Corporation shall not
take any of the following actions (each, a "Series B Preferred Stockholder Major
Decision") without first submitting such Series B Preferred Stockholder Major
Decision to a vote by the holders of Series B Preferred Stock, voting separately
as a class:

<PAGE>


the fully diluted shares of capital stock of the Corporation as of the date
hereof (the "25% Management Stock Amount") shall NOT be counted toward such ten
percent (10%) limitation, such issuances to the Management Stockholders and

holders of the Series B Preferred Stock;

                           (C) the cessation of the business of the Corporation;

                           (D) the issuance of shares of capital stock of the
Corporation with liquidation and dividend rights junior to those afforded to the
Series B Preferred Stock ("Series B Junior Stock") to any person or entity (a
"Series B Adverse Junior Stock Purchaser") which is actively engaged in
substantially the same business or businesses in which any corporation which
owns more that fifty percent (50%) of the voting capital stock of the holder of
Series B Preferred Stock is actively engaged ("Series B Adverse Junior Stock");

                           (E) any sale, transfer or other disposition by the
Corporation of all or any substantial portion of its assets whether by asset or

adversely 


                                       42


<PAGE>


affects the Series B Preferred Stockholder in its capacity as the Series B
Preferred Stockholder.

                           (K) Such other actions or proposed actions by the
Corporation that the Series B Preferred Stockholder and the Corporation shall,
in a written agreement between them (a "Major Decision Agreement"), agree shall
constitute additional Series B Preferred Stock Major Decisions requiring the
affirmative vote or consent of the Series B Preferred Stockholder. A Major
Decision Agreement may provide remedies to the Series B Preferred Stockholder
for the Corporation's failure or refusal to secure the affirmative vote or
consent of the Series B Preferred Stockholder for any such additional Major
Decision, in addition to the remedies otherwise provided by these Articles.

                           (ii) CORPORATION ENTITLED TO TAKE CERTAIN ACTIONS
WITHOUT APPROVAL OF SERIES B PREFERRED STOCKHOLDERS. If a Series B Preferred
Stockholder Major Decision, other than an issuance of Series B Adverse Junior
Stock, is not approved by the holders of a majority of the then outstanding
shares of Series B Preferred Stock pursuant to the provisions of subparagraph
(i) hereof, then the Corporation shall nonetheless be entitled to take any of
such actions constituting such a Series B Preferred Stockholder Major Decision,
but shall provide written notice to that effect to the holders of Series B
Preferred Stock no later than ninety (90) days prior to the date such action is
to be effective and the holders of Series B Preferred Stock shall be entitled,
by delivery of a written notice to the Corporation at the principal office of
the Corporation not less than twenty-one (21) days prior to the date such action
is to be effective, to require the Corporation to redeem all, but not less than
all, of the then issued and outstanding shares of Series B Preferred Stock
pursuant to the provisions of Section C.3(a)(ii) hereof.

                           (iii) SERIES B ADVERSE JUNIOR STOCK; SPECIAL
PROVISIONS. If the Series B Preferred Stockholders do not approve an issuance of
Series B Junior Stock that they believe is Series B Adverse Junior Stock
pursuant to the provisions of subparagraph (i) hereof, then, upon the
affirmative vote of a majority of the directors of the Corporation other than
the Series B Preferred Directors, the Corporation shall be entitled, for a
period of sixty (60) days following the election of the holders of Series B
Preferred Stock, not to approve an issuance of such stock, and to require
arbitration under the expedited procedures set forth herein of whether the
Series B Preferred Stockholders or their affiliates have legitimate business
interests that are materially adverse to such Purchaser. Such arbitration shall
be conducted by three arbitrators, two of whom (the "Party Designated
Arbitrators") shall be selected by the parties, and the third of whom shall be a
"Neutral Arbitrator" selected by the Party Designated Arbitrators. The
Corporation shall designate its Party Designated Arbitrator in a written notice
to the holders of Series B Preferred Stock, and within five (5) days thereafter,
such holders of Series B Preferred Stock shall designate its Party Designated

                                       43


<PAGE>


Arbitrator. Within five (5) days thereafter, the two Party Designated
Arbitrators shall agree upon and appoint a Neutral Arbitrator, who shall be an
attorney experienced in the health care business. The only issue to be
determined in the arbitration shall be whether the proposed recipient of Series
B Junior Stock has legitimate business interests which are materially adverse to
the holders of Series B Preferred Stock. The arbitration shall be concluded
within sixty (60) days of the date of the Corporation's written notice. The
determination of the arbitrators so appointed shall be final and conclusive upon
the parties. If the arbitrators determine that the proposed purchaser is a
Series B Adverse Junior Stock Purchaser, then the Corporation may nonetheless
proceed to issue such shares of Series B Adverse Junior Stock to such purchaser,
but shall provide written notice to that effect to the holders of Series B
Preferred Stock no later than 30 days prior to the date such issuance is
consummated, and the holders of Series B Preferred Stock shall thereupon become
entitled to exercise their rights to require the Corporation to redeem all, but
not less than all, of the issued and outstanding shares of Series B Preferred
Stock pursuant to the provisions of Section C.3.(a)(iii) hereof.

                           (f) Method of Approval. Whenever any action described
herein requires the action of holders of Series B Preferred Stock, such action
shall be deemed to have occurred upon the approval of holders of a majority of
the then issued and outstanding shares of Series B Preferred Stock at a duly
convened meeting of such stockholders or by their written consent in accordance
with the then applicable provisions of the MGCL, and the Corporation, in
undertaking any action with respect to such holders, shall be entitled to rely
upon a certificate signed by such holders to that effect.

                            2.      DIVIDENDS.

                           (a) Accrual of Dividends Before April 1, 2000.
Beginning as of December 1, 1995 and prior to April 1, 2000, cash dividends at
the rate of One Dollar and Nine and Seven-Tenths Cents ($1.097) per share per
annum shall accrue on the Series B Preferred Stock (whether or not earned or
declared or payment is legally available therefor) in equal quarterly
installments, commencing on the first day of January 1996, and continuing
thereafter on the first day of each month of April, July, October, January and
shall accrue interest at the rate of 9.75% (based upon a 365 day year)
compounded quarterly on all such unpaid dividend amounts.

                           (b) Payment of Dividends Before April 1, 2000.
Dividends and interest accrued on or with respect to accrual dates occurring
prior to April 1, 2000 shall be payable (either as part of a Series B Redemption
Price (as defined below) or liquidation payment, or otherwise) prior to April 1,
2000 only after all dividends and interest accrued on or with respect to the
Series A Preferred Stock have been fully paid and only upon (i) the liquidation
of the Corporation as herein provided, or (ii) the 

                                       44


<PAGE>


redemption or conversion of such share of Series B Preferred Stock, and if not
paid upon liquidation, redemption or conversion on or prior to April 1, 2000,
the amount of all such accrued dividends and interest payments shall from and
after April 1, 2000 become an unsecured obligation of the Corporation, bearing
interest at the rate, and being payable at the times, and upon the conditions,
set forth with respect to dividend payments in Section 2(c) below.

                           (c) Payment of Dividends on or After April 1, 2000.
Beginning on April 1, 2000, cash dividends, at the per annum rate of 100 basis
points over The Wall Street Journal Prime Rate as of the last business day prior
to April 1, 2000, shall accrue on the original issue price of all shares of
Series B Preferred Stock outstanding (whether or not earned or declared by the
Board), in equal quarterly installments on the first day of each month of April,
July, October and January. All such accrued dividends shall be declared by the
Board (if funds are at such time legally available therefor) and shall be
payable to each holder of Series B Preferred Stock on each such scheduled
quarterly date (as set forth above) if, at the time of payment (i) all dividends
and interest accrued on or declared with respect to the Series A Preferred Stock
have been fully paid, and (ii) funds for the full payment of such quarterly
dividend on all shares of Series B Preferred Stock then outstanding are legally
available therefor under the laws of the State of Maryland as then in effect.

                           (d) Declaration Date. The date on which the Board
shall consider the payment of a particular quarterly dividend on the Series B
Preferred Stock pursuant to Section C.2.(c) hereof shall be any date that is
prior to the date on which such quarterly dividend would be payable if declared,
and which is not more than seventy-five (75) days prior to such quarterly
dividend payment date.

                           (e) Reduction of Capital. If at any time the Board
considers the payment of any quarterly dividend pursuant to Section C.2.(c)
hereof (i) funds for the full payment of such quarterly dividend are not then
legally available therefor under the laws of the State of Maryland as then in
effect as applied to the then effective capitalization of the Corporation, and
(ii) funds for the payment of such quarterly dividend would be legally available
if the stated capital accounts of the Corporation were reduced or capital
surplus was revalued, then, in such event, the Board shall reduce the stated
capital at least to the extent necessary to declare and pay such dividend or
cause a revaluation of capital surplus if such reduction of capital or valuation
of surplus would be permissible under the laws of the State of Maryland as then
in effect and unless the exercise of the Board's fiduciary duty prevents such
reduction.

                           (f) Limitation on other Dividends; Payments. So long
as any shares of Series B Preferred Stock remain outstanding, (i) no dividends
shall be declared or paid upon, nor shall any dividend or other distribution be
made with respect 


                                       45


<PAGE>


to, any shares of any other class or series of stock or equity interest of the
Corporation other than the Series A Preferred Stock or any Subsidiary without
the consent of each of the Series B Preferred Stock Directors, and (ii) no
shares of any class of stock or equity interest of the Corporation or any
Subsidiary other than the shares of Series B Preferred Stock and Series A
Preferred Stock shall be redeemed, retired, purchased or otherwise acquired by
the Corporation, except purchases of the Corporation's interests in a Subsidiary
at the time of its organization. Notwithstanding the foregoing, the Corporation
may (iv) effect Permitted Redemptions pursuant to Section A.5; and (v) may
redeem shares of capital stock of or equity interests in any wholly-owned
Subsidiary.

                   3.      REDEMPTION.

                            (a)     OPTIONAL REDEMPTION BY HOLDERS.


                           (i) Permitted Time for Optional Redemption. At the
written request of any holder of Series B Preferred Stock, sent by such holder
to the Corporation at the principal office of the Corporation, during the
ninety-two (92) day period beginning on March 1, 2000, and ending on June 1,
2000, the Corporation shall, within ninety (90) days of the date of such request
(a "Series B Redemption Date") redeem for cash out of any funds legally
available therefor all, but not less than all, of the then issued and
outstanding shares of Series B Preferred Stock held by the holders making such
request, at an amount per share of Series B Preferred Stock equal to the greater
of (A) the then "fair market value" (as such term is defined in Section 3(d)(ix)
below) of such share, including, for purposes of calculating such fair market
value, the sum of all accumulated and unpaid interest and dividends on such
share of Series B Preferred Stock, whether or not such dividends have been
declared by the Corporation to the date such share is actually redeemed, or (B)
the sum of the issue price of such share plus all accumulated and unpaid
interest and dividends thereon, whether or not such dividends have been declared
by the Corporation to the date such share is actually redeemed.

                           (ii) Permitted Redemption Resulting from Certain
Unapproved Series B Preferred Stockholder Major Decisions. If the Corporation
elects to take any action constituting a Series B Preferred Stockholder Major
Decision (other than the issuance of Series B Adverse Junior Stock) without the
approval of the holders of Series B Preferred Stock (as permitted pursuant to
the provisions of Section B.1.(e)(ii) hereof), the Corporation shall give notice
of such election to each holder of Series B Preferred Stock at least ninety (90)
days prior to the date such action is to be effective, and the holders of Series
B Preferred Stock shall be entitled, by delivery of a written notice to the
Corporation at the principal office of the Corporation not less than twenty-one
(21) days prior to the date such action is to be effective, to request the
Corporation 


                                       46


<PAGE>


to redeem, and the Corporation shall redeem out of any funds legally available
therefor, all (but not less than all) of the then issued and outstanding shares
of Series B Preferred Stock then held by the holders requesting redemption, at
an amount per share of Series B Preferred Stock equal to the greater of (A) the
then fair market value of such share (including, for purposes of calculating
such fair market value, the sum of all accumulated and unpaid interest and
dividends on such share of Series B Preferred Stock, whether or not such
dividends have been declared by the Corporation to the date such share is
actually redeemed) or (B) the sum of the issue price of such share plus all
accumulated and unpaid interest and dividends thereon, whether or not such
dividends have been declared by the Corporation to the date such share is
actually redeemed. To the extent that net cash proceeds are received by the
Corporation as the result of the taking of such action constituting such a
Series B Preferred Stockholder Major Decision, other than the Series B Preferred
Stockholder Major Decisions described in Section C.3(a)(iii) below, which shall
be treated as provided therein, (i) the Corporation shall pay any redemption
price in cash to the holders of Series B Preferred Stock, such cash to be paid
pro rata among the holders of Series B Preferred Stock requesting such
redemption (with such redemption being a condition precedent to the
Corporation's receipt of such net proceeds) upon the occurrence of such action
(a "Series B Redemption Date"). To the extent that such net cash proceeds
received by the Corporation as a result of taking such Series B Preferred
Stockholder Major Decision are insufficient to enable the Corporation to make
full payment in cash, the Corporation may pay the balance due with respect to
the redemption of such shares within 180 days of such request.

                           (iii) Effect of Issuance of Series B Adverse Junior
Stock. If the Corporation elects to issue shares of Series B Adverse Junior
Stock after a determination by the arbitrators appointed pursuant to Section
C.1(e)(iii) hereof that the purchaser thereof is a Series B Adverse Junior Stock
Purchaser, then the holders of Series B Preferred Stock shall be entitled, by
delivery of a written notice to the Corporation at the principal office of the
Corporation within ninety (90) days after the date of issuance of such shares by
the Corporation, to request the Corporation to redeem, and the Corporation shall
redeem, all but not less than all of the issued and outstanding shares of Series
B Preferred Stock held by holders requesting redemption. Such redemption payment
shall be made in cash prior to or contemporaneously with such issuance if a
request for redemption is made thirty (30) or more days prior to the date
specified for issuance by the Corporation in its notice of issuance, and
otherwise no sooner than 180 days after the date of such request but in all
events within one (1) year of such request (a "Series B Redemption Date"). The
Corporation shall also, on or before the effective date of such redemption,
secure the complete and unconditional release of all then effective guarantees
of indebtedness of the Corporation by the redeeming Series B Stockholder and
shall also pay or cause to be paid in full all of the monies owed by the
Corporation to such redeeming Series B Stockholder pursuant to or as a result of
such guarantee or any instrument, agreement or other document 


                                       47


<PAGE>


executed and delivered by the Corporation to the redeeming Series B Stockholder
to induce the redeeming Series B Stockholder to enter into such guarantee. The
redemption price shall in all events be an amount per share of Series B
Preferred Stock equal to the greater of (A) the purchase price per share of
Series B Adverse Junior Stock to be paid, on a fully diluted basis, by the
purchaser of such shares, or (B) the then fair market value of such share of
Series B Preferred Stock as calculated pursuant to subparagraph (i) hereof, or
(C) the product of (I) one and one half (1.5) times the sum of (II) the
liquidation preference of such shares, including therein all accumulated and
unpaid dividends and interest thereon (whether or not such dividends have been
declared by the Corporation) to the date such share is actually redeemed.
Interest shall accrue on the amount of the fair market value per share at a rate
of nine and three-fourths percent (9.75%) per annum from the date such holders
of Series B Preferred Stock deliver notice of their redemption request to the
Corporation until the full payment of all amounts payable with respect to such
redemption has been paid in cash by the Corporation.

                           (iv) Redemption Pursuant to Securities Purchase
Agreement. Upon the written request of the holder of Series B Preferred Stock
pursuant to Section 5.3(e) the Securities Purchase Agreement, the Corporation
shall redeem the then issued and outstanding shares of Series B Preferred Stock
held by such holder according to the terms of the Securities Purchase Agreement.

                  (B) MANDATORY REDEMPTION BY THE CORPORATION. Upon the
occurrence of any Non-Compliance (as defined in Section C.6), the Corporation
shall redeem all, but not less than all, of the shares of Series B Preferred
Stock then held by each holder at the redemption price as calculated pursuant to
the provisions of Section C.3.(a)(i), within ten (10) business days after the
occurrence of such Non-Compliance. Any such redemption shall not be in lieu of
or in any way limit any other rights which such holders may have (at law or in
equity) in connection with the event giving rise to their right of redemption.

                            (C)     OPTIONAL  REDEMPTION BY THE CORPORATION.

                           (i) Optional Redemption in 2000. If the holders of
Series B Preferred Stock fail to request redemption of their shares of Series B
Preferred Stock within the ninety-two (92) day period provided in Section
C.3(a)(i) hereof for such optional redemption, and if such shares have not
otherwise been converted to shares of Class C Common Stock, then the Corporation
may, upon at least thirty (30) days prior notice delivered at any time after the
expiration of such applicable period (a Series B "Redemption Date"), redeem all,
but not less than all, of the outstanding shares of Series B Preferred Stock at
redemption price per share of Series B Preferred Stock equal to the greater of
(i) the then "fair market value" (calculated, if the Corporation and the Series
B Preferred Stockholder are unable to agree, according to 


                                       48


<PAGE>


the procedures set forth in Section 3(d)(ix) below) of such share, including for
purposes of calculating such fair market value, the sum of all accumulated and
unpaid interest and dividends on such share of Series B Preferred Stock, whether
or not such dividends have been declared by the Corporation to the date such
share is actually redeemed, or (ii) the sum of the issue price of such share
plus an amount equal to the amount of all accumulated and unpaid dividends and
interest on such share of Series B Preferred Stock, whether or not such
dividends have been declared by the Corporation to the date such share is
actually redeemed.

                           (ii) Redemption Pursuant to Securities Purchase
Agreement. The Corporation may redeem the then issued and outstanding shares of
Series B Preferred Stock pursuant to and according to the terms and provisions
of Section 5.3(e) of the Securities Purchase Agreement.


                            (D)     GENERAL PROVISIONS FOR REDEMPTIONS.

                           (i) Series B REDEMPTION PRICE. Each amount payable by
the Corporation pursuant to Section C.3(a) through (c) hereof respectively, is
referred to as the "Series B Redemption Price".

                           (ii) EFFECT OF REDEMPTION. Provision for payment of
the Series B Redemption Price for shares of Series B Preferred Stock having been
made by the Corporation, and for so long as there shall be no default in the
payment of deferred portions of the Series B Redemption Price, then (A) the
shares of Series B Preferred Stock designated for redemption in any notice shall
not be entitled to any dividends accruing after the specified Redemption Date,
and (B) on such Redemption Date all rights of the respective holders of such
shares, as stockholders of the Corporation by reason of the ownership of such
shares of Series B Preferred Stock, shall cease, except the right to receive the
Redemption Price upon presentation and surrender of the respective certificates
representing such shares.


                           (iii) DEFERRED PAYMENT FOR CERTAIN APPROVED SERIES B
PREFERRED STOCKHOLDER MAJOR DECISIONS. On any Series B Redemption Date resulting
from the failure of the holders of Series B Preferred Stock to approve (A) a
sale of all or substantially all of the assets of the Corporation whether by
asset or stock sale, or otherwise for consideration other than all cash or (B)
conveyance, transfer, or lease by the Corporation of all or any substantial
portion of its assets to any person or entity, or (C) a consolidation or merger
referred to in Section C.1(e)(1)(G) above, the Corporation may, at its election,
in lieu of making payment in full in cash, prior to the consummation of any such
transaction, pay to each holder of shares of Series B Preferred Stock an amount
in cash equal to one-half (1/2) of the total Series B Redemption Price, and may
issue a promissory note of the Corporation in an amount equal to the balance of
such Series B Redemption Price; provided however, that in the 


                                       49


<PAGE>


case of (A) above the Corporation shall be obligated to pay to the holders of
the Series B Preferred Stock an additional pro rata amount of cash (and shall be
entitled to reduce the principal amount of any note referred to in (iv) below),
if an to the extent it receives any cash as a result of such a transaction.



                           (iv) PROMISSORY NOTE. Any promissory note referred to
in subparagraph (iii), above, shall be payable in two (2) equal annual
installments, commencing on the one (1) year anniversary of the Series B
Redemption Date, of principal and interest and such interest shall accrue at the
then prime rate (the "Prime Rate") of the Corporation's primary banking
institution (or, if there be no such institution, the prime rate of interest as
published in the Wall Street Journal, from time to time) plus one hundred (100)
basis points. The obligations of the Corporation to make payment under such note
shall be secured by a perfected security interest in the Corporation's accounts
receivable (not more than 90 days' due at the date of perfection) with an
aggregate value of not less that 120% of all amounts payable under such note
from time to time, which recurring interest lien shall be subordinated only with
respect to payments and priority to any lien(s) granted to any of the
Corporation's lending financial institutions, incurred in accordance with these
designations.


                           (v) RETIREMENT OF SHARES. Shares of Series B
Preferred Stock that have been redeemed, purchased or otherwise acquired by the
Corporation shall be retired and may not be reissued.

                           (vi) SUBORDINATION OF SERIES B REDEMPTION PRICE. If,
at the time the Series B Redemption Price is payable to the holders of the
Series B Preferred Stock, the Series A Redemption Price is also payable to the
holders of the Series A Preferred Stock or the Series A Preferred Stock has been
designated for redemption pursuant to the terms of Section B.3, no payment shall
be made to the holders of Series B Preferred Stock in respect of the Series B
Redemption Price unless and until the Series A Redemption Price shall have been
paid in full to the holders of the Series A Preferred Stock.

                           (vii) EFFECT OF LEGAL RESTRICTIONS ON PAYMENT. If the
Redemption Price for any such shares cannot be paid in full because the
Corporation is prohibited by law from making such payment, then those funds that
are legally available will be used to pay (ratably if necessary) accrued but
unpaid interest, then accrued but unpaid dividends, and then to redeem the
maximum possible number of shares of Series B Preferred Stock ratably among the
holders thereof determined by multiplying the total number of shares of Series B
Preferred Stock to be redeemed times a fraction, the numerator of which shall be
the total number of such shares then held by each such holder and the
denominator of which shall be the total number of such shares then outstanding.
The shares of Series B Preferred Stock not redeemed shall remain 


                                       50


<PAGE>


outstanding and be entitled to all rights and preferences provided herein;
provided, however, at any time thereafter when additional funds of the
Corporation are legally available for the redemption of such shares of Series B
Preferred Stock, such funds will be used, at the end of the next succeeding
fiscal quarter, to redeem the balance of such shares, or such portion thereof
for which funds are then legally available. If fewer than the total number of
shares of Series B Preferred Stock represented by any certificate are redeemed,
a new certificate representing the number of unredeemed shares will be issued to
the holder thereof without cost to such holder within three business days after
surrender of the certificate representing the redeemed shares of Series B
Preferred Stock.

                           (viii) RESTRICTIONS ON CORPORATE ACTIONS. If the
Corporation for any reason fails to redeem any shares of Series B Preferred
Stock in accordance with this Section C.3 on or prior to the Redemption Date
specified herein, then, notwithstanding anything to the contrary contained in
these Articles of Incorporation, the Corporation may not incur any Indebtedness
(unless the proceeds of such incurrence of Indebtedness are used to make all
overdue redemption payments in respect of the Series B Preferred Stock,
including payments of accrued but unpaid dividends or interest) without the
prior written consent of the holders of the Series B Preferred Stock voting
separately as a class; provided, however, that, subject to the restriction set
forth in Section C.1(c)(i), if such restriction is then in force, the
Corporation may incur Indebtedness without the aforesaid approval if (A) the
proceeds of such borrowing are used to pay obligations of the Corporation
arising in the ordinary course of business as they become due and payable, or
otherwise to maintain the operations of the Corporation at the then current
level and not to expand the operation of the Corporation in any material
respect, whether through expansion or enhancement of, or addition, to the
Corporation's then current activities, facilities, equipment or other capital
assets, or otherwise, (B) the Corporation provides prior written notice of such
borrowing to all holders of Series B Preferred Stock, which notice shall include
a statement of the intended use of the proceeds of such borrowing, and (C)
promptly upon request therefor, the Corporation shall provide to any holder of
Series B Preferred Stock a certificate signed by the President and Chief
Financial Officer of the Corporation certifying as to the allocation and use of
the proceeds of any such borrowing.

                           (ix) APPRAISAL. Within fourteen (14) days of any
written request of any holder of shares of Series B Preferred Stock from time to
time, the fair market value of the Series B Preferred Stock shall be determined
by an appraiser or appraisers shall according to the terms and procedures of
Section B.3(d)(viii), except that all references shall be to Series B Preferred
Stock and Stockholders rather than Series A Preferred Stock and Stockholders.

                           (x) MULTIPLE HOLDERS OF SERIES B PREFERRED STOCK. If
the Series B Preferred Stock is at any time held by more than one person or
entity, the request for 



                                       51


<PAGE>


redemption pursuant to this Section C.3 by the holders of at least fifty-one
percent (51%) of the then issued and outstanding shares of Series B Preferred
Stock shall constitute the request for redemption by the holders of all of the
then issued and outstanding shares of Series B Preferred Stock and all such
holders of Series B Preferred Stock shall redeem their shares of Series B
Preferred Stock pursuant to this Section C.3 upon the receipt of notice from
holders of at least fifty-one percent (51%) of the then issued and outstanding
shares of Series B Preferred Stock.

                   4.      CONVERSION RIGHTS.

                            (A)     OPTIONAL CONVERSION BY HOLDER.

                           (i) General Provisions. All, but not less than all,
of the issued and outstanding shares of Series B Preferred Stock shall be
convertible, without the payment of any additional consideration, into shares of
Class C Common Stock, at the option of the holders of the shares of Series B
Preferred Stock, at any time prior to 5:00 P.M. (EST) on FEBRUARY 24, 2000;
provided, however, that if such conversion occurs at any time during the 60 day
period referred to in Section 3(a)(ii) (other than as the result of the adoption
of a Business Plan as set forth in Section 1(e)(i)(A) (above) or pursuant to
Section 3(a)(iii) above, after the Corporation elects to take any action
constituting a Series B Preferred Stockholder Major Decision without the
approval of the holders of the Series B Preferred Stock, such conversion shall
not be deemed to be an "optional conversion" governed by the provisions of this
Section 4(a), but shall be governed by the provisions relating to "Automatic
Conversions" set forth in Section 4(b) below. Each such share of Series B
Preferred Stock shall be convertible at such time into one fully-paid and
nonassessable share of Class C Common Stock, subject to adjustment as provided
in Section C.4.(e) below (the "Series B Conversion Rate"). The holders of shares
of Series B Preferred Stock requesting conversion of shares into shares of Class
C Common Stock shall send a written notice to the Corporation, at the principal
office of the Corporation, requesting such conversion. The holders shall, as
soon thereafter as practicable, deliver the certificates therefor, duly endorsed
for transfer, at the principal office of the Corporation or any transfer agent
for the Series B Preferred Stock. The Corporation shall, as soon as practicable
thereafter, issue and deliver to the holders a certificate or certificates for
the number of such shares of Class C Common Stock to which the holders shall be
entitled, a check payable to the holders in the amount of any cash in lieu of
issuance of any fractional share, and the amount of any cumulative dividends and
interest accrued but unpaid (unless, and to the extent, the Corporation elects
to issue additional shares of Class C Common Stock in lieu of such dividends and
interest pursuant to Section C.4(d)) on such shares. The conversion shall be
deemed to have been made immediately prior to the close of business on the date
of receipt of the notice. The persons entitled to receive the shares of Class C
Common Stock issuable upon such conversion shall be treated for all purposes as
the record holder or holders of such shares of Class C Common Stock


                                       52


<PAGE>


on such date, and the shares of Series B Preferred Stock converted shall
immediately be canceled and may not be reissued.

                           (ii) Multiple Holders of Series B Preferred Stock. If
the Series B Preferred Stock is at any time held by more than one person or
entity, the request for conversion pursuant to this Section C.4 by the holders
of at least fifty-one percent (51%) of the then issued and outstanding shares of
Series B Preferred Stock shall constitute the request for conversion by the
holders of all of the then issued and outstanding shares of Series B Preferred
Stock and all such holders of Series B Preferred Stock shall convert their
shares of Series B Preferred Stock pursuant to this Section C.4 upon the receipt
of notice from holders of at least fifty-one percent (51%) of the then issued
and outstanding shares of Series B Preferred Stock.

                           (B) AUTOMATIC CONVERSION. If the holders of Series B
Preferred Stock have not earlier exercised their rights to require the
Corporation to redeem their shares of Series B Preferred Stock pursuant to the
provisions of Section C.3.(a) hereof, all of the outstanding shares of Series B
Preferred Stock shall, together with all other then outstanding shares of the
Corporation's preferred stock or other capital stock with rights to convert into
shares of Common Stock, be converted into fully-paid and nonassessable shares of
Class C Common Stock at the Series B Conversion Rate upon the earlier to occur
of the closing or other consummation of (i) any Qualified Public Offering, (ii)
any Non-Qualified Public Offering, (iii) any combination, consolidation or
merger where the Corporation is not the survivor, (iv) any sale, exchange or
other disposition of all or substantially all of the Corporation's assets,
whether by asset or stock sale or otherwise, or (v) any election by the holders
of Series B Preferred Stock to effect an "Optional Conversion" during any period
during which the holders of the Series B Preferred Stock may cause the
Corporation to redeem shares of their Series B Preferred Stock pursuant to the
provisions of Section 3(a)(ii) or 3(a)(iii), above. In the case of the
occurrence of any of (i) through (v) above, all shares of Series B Preferred
Stock which have not been converted into shares of Class C Common Stock, shall
be subject to mandatory redemption by the Corporation pursuant to the provisions
of Section C.3.(iii) hereof. Shares of Class C Common Stock received pursuant to
this Section 4.(b) shall be subject to the provisions of Article IV, Section A.4
in the event of a Qualified Public Offering or Non-Qualified Public Offering,
and shall thereupon immediately be reclassified as shares of Class A Common
Stock. At least twenty (20) days prior written notice of the date fixed and
place designated for conversion shall be sent by first class mail, postage
prepaid, to the address of each holder of shares of Series B Preferred Stock as
shown in the records of the Corporation. On or before the date fixed for
conversion, each holder of shares of Series B Preferred Stock shall surrender
the certificates representing such shares to the Corporation at the place
designated in such notice and shall thereafter receive certificates for the
number of full shares of Common Stock to which such holder is entitled. Until
such time as holders of certificates theretofore representing shares of 

                                       53


<PAGE>


Series B Preferred Stock have surrendered them for exchange as provided herein,
no dividends shall be paid with respect to any shares represented by such
certificates and no payment for fractional shares shall be made.

                           (c) NO FRACTIONAL SHARES. No fractional shares of
Common Stock shall be issued upon conversion of shares of Series B Preferred
Stock. In lieu of any fractional share, the Corporation shall pay a cash
adjustment in respect of such fractional interest equal to the fair market value
of such fractional interest as determined by the Board.

                           (d) PAYMENT OF DIVIDENDS AND INTEREST. At the time of
the conversion of any shares of Series B Preferred Stock, whether mandatory or
optional, and after payment in full by the Corporation of all amounts of
interest and cumulative dividends accrued but unpaid with respect to Series A
Preferred Stock, the Corporation shall pay to the holder of such shares of
Series B Preferred Stock the sum of all interest and cumulative dividends
accrued but unpaid with respect to such Series B Preferred Stock, whether or not
such dividends shall have been declared by the Corporation to the date of
conversion.

                           (e) ADJUSTMENTS; ANTIDILUTION. The number of shares
of Class C Common Stock issuable upon the conversion of the Series B Preferred
Stock shall be subject to adjustment from time to time upon the happening of
certain events as follows:

                           (i) DIVIDENDS, SPLITS. If the Corporation declares a
dividend payable in its shares of its Common Stock, splits any of its Common
Stock or combines any of its outstanding shares of Common Stock into a smaller
number, then the number of fully-paid and nonassessable shares of Class C Common
Stock into which each share of Series B Preferred Stock may be converted shall
forthwith be adjusted by multiplying one (1) by a fraction (A) the numerator of
which shall be the total number of outstanding shares of Common Stock
immediately after such dividend, stock split or combination, and (B) the
denominator of which shall be the total number of outstanding shares of Common
Stock immediately prior to such dividend, stock split or combination.

                           (ii) REORGANIZATION, RECLASSIFICATION. In the event
of a reorganization, share exchange, or reclassification, other than a change in
par value, or from par value to no par value, or from no par value to par value
or a transaction described in subsection (iii) or (iv) below, each share of
Series B Preferred Stock shall, after such reorganization, share exchange or
reclassification, be convertible into the kind and number of shares of stock or
other securities or property of the Corporation to which the holder of Series B
Preferred Stock would have been entitled if the holder had held the Class C
Common Stock issuable upon conversion of its Series B Preferred Stock
immediately prior to such reorganization, share exchange, or reclassification,
or to which the Series B Preferred Stock is actually entitled, but not both.


                                       54

<PAGE>


                           (iii) CONSOLIDATION, MERGER, SALE OF ASSETS. In the
event of a merger or consolidation or sale, exchange or other disposition of
all, or substantially all of the Corporation's assets, to which the Corporation
is a party, each share of Series B Preferred Stock shall, after such merger or
consolidation, be convertible into the kind and number of shares of stock and/or
other securities, cash or other property to which the holder of such share of
Series B Preferred Stock would have been entitled if the holder had held the
Class C Common Stock issuable upon conversion of its shares of Series B
Preferred Stock immediately prior to such consolidation or merger or sale of
assets, or to which the Series B Preferred Stock is actually entitled, but not
both.

                           (iv) CERTAIN ISSUANCES OF ADDITIONAL SHARES OF COMMON
STOCK. If the Corporation shall issue any additional shares of Common Stock --
other than securities to be issued (i) to the public pursuant to any Qualified
Public Offering or Non-Qualified Public Offering, (ii) to officers, directors,
or employees of the Corporation as part of a stock option plan, restricted stock
plan, employee stock purchase plan, employment agreement, or other employee
stock plan or agreement, implemented by the Board, provided that the aggregate
numbers of such shares issued shall not exceed ten percent (10%) of the fully
diluted capital stock of the Corporation calculated as of the time of the
issuance, (iii) to Management Stockholders and other executive employees of the
Corporation, of an amount of Class A Common Stock not in excess of the 25%
Management Stock Amount, (iv) upon conversion of any shares of the Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock or the
exercise of any warrant to purchase shares of Common Stock held by the holder of
Series B Preferred Stock pursuant to the terms hereof, or (v) to the LP pursuant
to Article XIV of the Practice Participation Agreement in respect of the
issuance of Medical Holdings Limited Partnership of the Limited Partner
Interests (or options to purchase such Interests) from and after the time that
more than sixty-six (66) but less than one hundred (100) physicians hold such
Limited Partner Interests (or options to acquire such Interests) directly or
indirectly through their professional corporations -- for a consideration per
share of Common Stock less than the "conversion price," as adjusted or as
previously adjusted, in effect on the date immediately prior to such issuance,
then and in such event, such conversion price shall be adjusted, concurrently
with such issuance, to a price equal to the quotient obtained by DIVIDING:

                                    (1) an amount equal to (x) the sum of (A)
                  the total number of shares of Common Stock outstanding
                  immediately prior to such issuance or sale, plus (B) the total
                  number of shares of Common Stock issuable upon exercise of all
                  options, warrants and other rights convertible or exchangeable
                  for, or evidencing the right to purchase shares of, Common
                  Stock outstanding immediately prior to such issuance or sale,
                  multiplied by (C) the conversion price in effect immediately
                  prior to such issuance or sale, plus (y) the consideration, if
                  any, received or 



                                       55


<PAGE>


                  deemed to be received by the Corporation upon such issuance or
                  sale; BY

                                    (2) the sum of (A) the total number of
                  shares of Common Stock outstanding immediately after such
                  issuance or sale, plus (B) the total number of shares of
                  Common Stock issuable upon exercise of all options, warrants
                  and other rights convertible or exchangeable for, or
                  evidencing the right to purchase shares of, Common Stock
                  outstanding immediately after such issuance or sale.

For purposes of this Section C.4, the conversion price shall initially be $11.25
per share.

No adjustment of the conversion price shall be made under this Section
C.4.(e)(iv) upon the issuance of any additional shares of Common Stock that are
issued pursuant to the exercise of any warrants, options or other subscription
or purchase rights or pursuant to the exercise of any conversion or exchange
rights in any convertible securities if any such adjustments shall previously
have been made upon the issuance of any such warrants, options or other rights
or upon the issuance of any convertible securities (or upon the issuance of any
warrants, options or any rights therefor) pursuant to Sections 4(v) or 4(vi)
hereof.

                           (v) ISSUANCE OF WARRANTS, OPTIONS OR OTHER RIGHTS. If
the Corporation at any time shall issue any warrants, options or other rights to
subscribe for or purchase any additional shares of Common Stock and the price
per share for which additional shares of Common Stock may at any time thereafter
be issuable pursuant to such warrants, options or other rights shall be less
than the conversion price per share in effect immediately prior to such
issuance, then such issue shall be deemed on issuance (as of the date of issue
of such warrants, options or other rights) of the total maximum number of shares
of Common Stock issuable pursuant to such warrants, options or other rights, and
the conversion price shall thereupon be adjusted as provided in Section
C.4.(e)(iv) hereof on the basis that the aggregate consideration for the
additional shares of Common Stock issuable pursuant to such warrants, options or
other rights, plus the minimum consideration to be received by the Corporation
for the issuance of additional shares of Common Stock pursuant to such warrants,
options, or other rights shall be deemed to be the consideration received by the
Corporation for the issuance of such warrants, options, or other rights.

                           (vi) CERTAIN ISSUANCES OF CONVERTIBLE SECURITIES. In
case the Corporation shall issue any securities convertible into Common Stock
and the consideration per share for which such additional shares of Common Stock
may at any time thereafter be issuable pursuant to the terms of such convertible
securities shall be less than the conversion price per share in effect
immediately prior to such issuance, 


                                       56


<PAGE>



then upon such issuance of such securities the conversion price shall be
adjusted as provided in Section C.4.(e)(iv) hereof on the basis that (i) the
maximum number of additional shares of Common Stock necessary to effect the
conversion or exchange of all such convertible securities shall be deemed to
have been issued as of the date of issuance of such convertible securities, and
(ii) the aggregate consideration for such maximum number of additional shares of
Common Stock plus the minimum consideration received by the Corporation for the
issuance of such additional shares of Common Stock pursuant to the terms of such
convertible securities shall be deemed to be the consideration received by the
Corporation for the issuance of such convertible securities. No adjustment of
the conversion price shall be made under this subsection upon the issuance of
any convertible securities which are issued pursuant to the exercise of any
warrants, options or other subscription or purchase rights therefor, if any such
adjustment shall previously have been made upon the issuance of such warrants,
options or other rights pursuant to Section C.4.(e)(v) hereof.

                           (vii) ADJUSTMENT OF SERIES B CONVERSION RATE. Upon
each adjustment of the conversion price under the provisions of this Section
C.4.(e), the conversion rate shall be adjusted to an amount determined by
dividing $11.25 by such adjusted conversion price. For example, if, as a result
of any of the foregoing, the conversion price were reduced to $9.00, each share
of Series B Preferred Stock would then be convertible into 1.25 shares of Class
C Common Stock.

                           (viii) OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS
UNDER THIS SECTION. The following provisions will be applicable to the making of
adjustments in conversion prices hereinabove provided in this Section B.4.(e):

                           (1) COMPUTATION OF CONSIDERATION. To the extent that
any additional shares of Common Stock or any convertible securities or any
warrants, options or other rights to subscribe for or purchase any additional
shares of Common Stock or any convertible securities shall be issued for cash
consideration, the consideration received by the Corporation therefor shall be
deemed to be the amount of the cash received by the Corporation therefor, or, if
such additional shares of Common Stock or convertible securities are offered by
the Corporation for subscription, the subscription price. To the extent that
such issuance shall be for a consideration other than cash, then the amount of
such consideration shall be deemed to be the fair value of such consideration at
the time of such issuance as determined in good faith by the Corporation's Board
after receipt of a fairness opinion, appraisal or similar independent
third-party advice determined by a person or entity jointly selected by the
Series B Preferred Directors, the Series A Preferred Directors, the Series C
Preferred Stock Directors and the other directors pursuant to procedures
substantially similar to those set forth in Section 6 of the Stockholders
Agreement. The consideration for any additional shares of Common Stock issuable
pursuant to any warrants, options or other rights to subscribe for or purchase
the same shall be the consideration received by the 


                                       57


<PAGE>


Corporation for issuing such warrants, options or other rights, plus the
additional consideration payable to the Corporation upon the exercise of such
warrants, options or other rights. The consideration for any additional shares
of Common Stock issuable pursuant to the terms of any convertible securities
shall be the consideration paid or payable to the Corporation in respect of the
subscription for or purchase of such convertible securities, plus the additional
consideration, if any, payable to the Corporation upon the exercise of the right
of conversion or exchange in such convertible securities. In case of the
issuance at any time of any additional shares of Common Stock or convertible
securities in payment or satisfaction of any dividend upon any class of stock
preferred as to dividends in a fixed amount, the Corporation shall be deemed to
have received for such additional shares of Common Stock or convertible
securities a consideration equal to the amount of such dividend so paid or
satisfied.

                           (2) READJUSTMENT OF CONVERSION PRICE. Upon the
expiration of the right to convert or exchange any convertible securities, or
upon the expiration of any rights, options or warrants, without conversion,
exchange or exercise, the issuance of which convertible securities, rights,
options or warrants effected an adjustment in the conversion price, such
conversion price shall forthwith be readjusted and thereafter be the price which
it would have been (but reflecting any other adjustments in the conversion price
made pursuant to the provisions of this Section C.4.(e) after the issuance of
such convertible securities, rights, options or warrants) had the adjustment of
the conversion price made upon the issuance or sale of such convertible
securities or issuance of rights, options or warrants been made on the basis of
the issuance only of the number of additional shares of Common Stock actually
issued upon conversion or exchange of such convertible securities, or upon the
exercise of such rights, options or warrants, and thereupon only the number of
additional shares of Common Stock actually so issued, if any, shall be deemed to
have been issued and only the consideration actually received by the Corporation
(computed as set forth in subsection C.4.(e)(viii)(1) hereof) shall be deemed to
have been received by the Corporation. If the purchase price provided for in any
such rights, options or warrants, or the additional consideration (if any)
payable upon the conversion or exchange of any convertible securities, or the
rate at which any convertible securities are convertible into or exchangeable
for shares of Common Stock changes at any time (other than under or by reason of
provisions designed to protect against dilution), the conversion price in effect
at the time of the change shall be adjusted to the conversion price that would
have been in effect at such time had such rights, options, warrants or
convertible securities still outstanding provided for such changed purchase
price, additional consideration or conversion rate, as the case may be, at the
time initially granted, issued or sold.

                           (3) OTHER ACTION AFFECTING COMMON STOCK. If the
Corporation shall take any action affecting the outstanding number of shares of
Common Stock, other than an action described in any of the foregoing subsections


                                       58


<PAGE>



4(e)(i) to (vii) hereof, inclusive, which in the opinion of the Corporation's
Board would have a materially adverse effect upon the rights of the holders of
the Series B Preferred Stock, the conversion price shall be adjusted in such
manner and at such time as the Board may determine to be equitable in the
circumstances.

                           (ix) NOTICES OF ADJUSTMENTS. Whenever the conversion
rate and conversion price is adjusted as herein provided, an officer of the
Corporation shall compute the adjusted conversion rate and conversion price in
accordance with the foregoing provisions and shall prepare a written instrument
setting forth such adjusted conversion rate and conversion price and showing in
detail the facts upon which such adjustment is based, and such written
instrument shall promptly be delivered to the record holders of the Series B
Preferred Stock, who shall approve such conversion rates and prices within 30
days of receipt. If holders of Series B Preferred Stock do not object in writing
during such 30 day period, they shall be deemed to have approved such conversion
rates and prices for all purposes hereof.

                           (f)RESERVATION OF SHARES. The Board shall at all
times reserve and keep available, out of its authorized but unissued shares of
Class C Common Stock, solely for the purpose of effecting the conversion of the
shares of Series B Preferred Stock, the full number of shares of Class C Common
Stock deliverable by the Corporation upon the conversion of all shares of Series
B Preferred Stock from time to time outstanding and otherwise issuable under
rights granted from the Corporation then existing.

                           (g)NO IMPLIED MODIFICATION OF TERMS. The provisions
of this Section C.4. shall not give, or be deemed to give, the Corporation the
power or authority to issue any shares of its capital stock or other securities
or to take any other action that it is expressly prohibited from issuing by
another provision hereof.

                   5.      LIQUIDATION RIGHTS.

                           (a) Upon any liquidation, dissolution or winding up
of the affairs of the Corporation, whether voluntary or involuntary, the holders
of shares of the Series B Preferred Stock shall be entitled to receive out of
the assets of the Corporation available for distribution to stockholders, before
any distribution or payment shall be made in respect of the holders of shares of
Common Stock or any other class or series of stock ranking junior to the Series
B Preferred Stock, a liquidating distribution in an amount equal to the greater
of (i) the sum of the "fair market value" per share of Series B Preferred Stock,
which shall include an amount per share equal to all cumulative dividends and
interest accrued but unpaid thereon, whether or not such dividends and interest
shall have been declared by the Corporation, to the date fixed for such
distribution or payment; or (ii) the sum of the original purchase price per
share of Series B Preferred Stock plus an amount equal to all cumulative
dividends and interest 


                                       59


<PAGE>


accrued but unpaid thereon to the date fixed for such distribution or payment;
provided, however, in either such event the amount of cash payable by the
Corporation shall not exceed the amount of cash paid to the Corporation by all
holders of such shares with respect to the purchase of such shares, including
the payment of any interest with respect thereto, through and including the date
of liquidation; and provided further, however, that no liquidating distribution
shall be paid in respect of Series B Preferred Stock unless and until all
amounts due to holders of Series A Preferred Stock as a liquidating distribution
pursuant to Section B.5(a) shall have been fully paid. The holders of shares of
Series B Preferred Stock shall not be entitled to receive any additional
distributive amounts upon such liquidation, dissolution or winding up of the
affairs of the Corporation resulting in any distribution of assets to
stockholders.

                           (b) If, upon any such liquidation, dissolution or
winding up of the affairs of the Corporation, the assets of the Corporation to
stockholders shall be insufficient to permit the payment in full to the holders
of Series B Preferred Stock of the amounts to which they are entitled, then all
of such available assets shall be distributed to the holders of shares of Series
B Preferred Stock ratably in proportion to the liquidation payment otherwise due
under Section C.5.(a) to each such holder and no amounts shall be distributed in
respect of any other share of capital stock of the Corporation other than Series
A Preferred Stock until all amounts distributable to holders of Series B
Preferred Stock have been distributed.

                           (c) The purchase or redemption by the Corporation of
stock of any class, in any manner permitted by law, shall not for the purpose of
this Section C.5. be regarded as a liquidation, dissolution or winding up of the
Corporation. Neither the consolidation nor merger of the Corporation with or
into any other corporation or corporations, nor the sale or transfer by the
Corporation of all or any part of its assets shall be deemed to be a
liquidation, dissolution or winding up of the Corporation for the purpose of
this Section C.5.

                           (d) At least thirty (30) days prior written notice of
any such liquidation, dissolution or winding up of the affairs of the
Corporation stating a payment date, the amount of the liquidation payments and
the place where said liquidation payments shall be payable, shall be sent by
first class mail, postage prepaid, to each holder of Series B Preferred Stock at
his address as shown on the records of the Corporation.

satisfy or secure the payment of such claim or judgment within sixty (60)
calendar days after the levy thereof and the Corporation's assets are thereby
released from the lien of such attachment;

                  D.       SERIES C PREFERRED STOCK.

                                     1.     VOTING RIGHTS.

                           (a) General Provisions. Holders of Series C Preferred
Stock shall be entitled to notice of each meeting of all of the Corporation's
stockholders, but shall not be entitled to notice of special or other meetings
of any class of Common Stock or of Series A Preferred Stock or Series B
Preferred Stock. The holders of shares of Series C Preferred Stock shall vote
with the holders of shares of Common Stock and Series A Preferred Stock and
Series B Preferred Stock on all matters submitted to a vote of stockholders and
not as a separate series or class, except as otherwise provided herein. Except
as otherwise provided herein, on all matters to be voted on by the Corporation's
stockholders, every holder of Series C Preferred Stock shall be entitled to
cast, in person or by proxy, that number of votes equal to the full number of
shares of Class C Common Stock into which such holder's Series C Preferred Stock
is then convertible.


                                       63


<PAGE>


                           (b) Series C Preferred Stock Directors. The holders
of shares of Series C Preferred Stock, voting as a single class, shall be
entitled to elect one (1) director of the Corporation until the Corporation's
1998 annual meeting of shareholders, and such director shall, under the
Corporation's By-laws, be entitled to serve on the Executive Committee of the
Corporation's Board of Directors until such time as there is a Qualified Public
Offering. At and after the Corporation's 1998 annual meeting of shareholders,
the holders of the Series C Preferred Stock, voting as a class, shall be
entitled to elect a total of two (2) Directors of the Corporation (such
individual director, or two directors, being referred to as the "Series C
Preferred Stock Directors") and one of such Directors shall, under the
Corporation's Bylaws, be entitled to serve on the Executive Committee of the
Corporation's Board of Directors until the occurrence of a Qualified Public
Offering. Where the holders of Series C Preferred Stock vote as a class, the
affirmative vote of a majority of the shares of Series C Preferred Stock
represented in person or by proxy at a meeting at which a quorum of Series C
Preferred Stock is present shall be sufficient to approve any matter with
respect to which said holders are entitled to vote; provided, however, that the
affirmative vote of a plurality of all votes cast in person or by proxy by the
holders of Series C Preferred Stock shall be sufficient to elect a Series C
Preferred Stock Director. The holders of Series C Preferred Stock, at any annual
meeting or upon a call of a special meeting of holders of Series C Preferred
Stock by holders of not less than twenty-five percent (25%) of the shares of
Series C Preferred Stock then outstanding, may remove any Series C Preferred
Stock Director at any time and from time to time, voting as a single class, by
the affirmative vote of eighty percent (80%) of all votes entitled to be cast
for the election of a Series C Preferred Stock Director, and may elect a
successor to fill any resulting vacancies for the remainder of the term of such
Series C Preferred Stock Director. If any Series C Preferred Stock Director
shall cease to be a director for any reason (including death, resignation,
removal or any other cause), the vacancy shall be filled by a vote of the
remaining Series C Preferred Stock Director or, if no Series C Preferred Stock
Director remains, by a vote of the holders of Series C Preferred Stock (unless,
with respect to removal, the holders of Series C Preferred Stock have elected a
successor Series C Preferred Stock Director pursuant to the provisions hereof).
If there is no such remaining director, then upon a call of a special meeting of
holders of Series C Preferred Stock, by any such holder, the vacancy shall be
filled by the vote of the holders of Series C Preferred Stock, voting as a
single class.

                           (c) Actions Requiring Votes of the Series C Preferred
Stock Director or Stockholder. Without the affirmative vote of each of the
Series C Preferred Stock Directors (or the sole Series C Preferred Stock
Director, when applicable) or the holders of Series C Preferred Stock, the
Corporation shall not:

                           (i) incur or permit any of its Subsidiaries (as
defined in Section B.1(d)(v)) to incur any Indebtedness (as defined in Section
B.1(d)(i)) as a result of which the outstanding Indebtedness of the Corporation
would on a consolidated 


                                       64


<PAGE>



basis exceed One Million Dollars ($1,000,000) in the aggregate; other than (A)
Indebtedness that is subordinated in right of dividends, redemption and
liquidation to the Series C Preferred Stock and/or (B) Indebtedness contemplated
in the Corporation's Operating Plan (the "Operating Plan") included in Section
3.6(b) of the Disclosure Schedule attached to the Stock Purchase Agreement dated
as of September 4, 1996 by and between the Company and the Series C Preferred
Stockholder (the "Stock Purchase Agreement") and attached thereto, as reduced by
the amount of the Series C Preferred Stockholder's investment in the
Corporation, which reduction shall be in an amount up to Twenty Million Dollars
($20,000,000); or

                           (ii) issue any shares of its capital stock with
liquidation, redemption or dividend rights senior to (or PARI PASSU with) the
liquidation, redemption or dividend rights of the Series C Preferred Stock; or

                           (iii) effect any amendment to these Amended and
Restated Articles of Incorporation or to the By-Laws of the Corporation that
adversely affects the holders of the Series C Preferred Stock or the Class C
Common Stock; or

                           (iv) pay any dividend with respect to the Series A
Preferred Stock or the Series B Preferred Stock prior to September 1, 1998
unless paid in connection with a redemption; or

                           (v) obligate the Corporation to do any of the
foregoing.

For purposes of this Section D.1(c), the holders of the Series C Preferred Stock
may take action to enforce their rights under this Section D.1(c) at a duly
called meeting of the Corporation's stockholders; provided, however, that the
exercise of such rights shall not require a meeting of the Corporation's
stockholders.

                           (d) Definitions. For purposes of this Section D, the
definitions set forth in Section B.1.(d) shall be applicable except that:

                           (i) In Section B.1(d)(i)(G)(x), the phrase "Series C
Preferred Stock" shall be substituted for "Series A Preferred Stock;"

                           (ii) "QUALIFIED PUBLIC OFFERING" shall mean any
public underwritten offering of the Corporation's Common Stock pursuant to an
effective registration statement filed with the Securities and Exchange
Commission pursuant to the Securities Act of 1933, as amended (the "1933 Act")
based upon a total market capitalization of the Corporation, at the time of such
offering, of at least 100 Million Dollars ($100,000,000), from which the Company
receives net proceeds of not less than Twenty-Five Million Dollars
($25,000,000).


                                       65


<PAGE>


                           (e) Method of Approval. Whenever any action described
herein requires the action of holders of Series C Preferred Stock, such action
shall be deemed to have occurred upon the approval of holders of a majority of
the then issued and outstanding shares of Series C Preferred Stock at a duly
convened meeting of such stockholders, or by their written consent (without
necessity for a meeting), and the Corporation, in undertaking any action with
respect to such holders, shall be entitled to rely upon a certificate signed by
such holders to that effect.

                  2.       DIVIDENDS.

                           (a) Accrual of Dividends. Subject to the provisions
of Sections 2(b) and 2(c) below, cash dividends shall accrue on shares of Series
C Preferred Stock issued pursuant to the Stock Purchase Agreement at the rate of
One Dollar and Forty Cents ($1.40) per share per annum and on shares of Series C
Preferred Stock issued pursuant to the Option Agreement at the rate of One
Dollar and Sixty Cents ($1.60) per share per annum, beginning on the date of
issuance of such shares (whether or not earned or declared or payment is legally
available therefor) and shall accrue interest at the rate of 8% (based upon a
365-day year) compounded quarterly on all such unpaid dividend amounts.

                           (b) Payment of Dividends. Unless canceled pursuant to
the provisions of Section 2(c) below, dividends and interest accrued on or with
respect to accrual dates shall be payable (either as part of a Series C
Redemption Price (as defined below) or liquidation payment, or otherwise) only
after all dividends and interest accrued on or with respect to the Series A
Preferred Stock and Series B Preferred Stock have been fully paid and only upon
(i) the liquidation of the Corporation as herein provided, or (ii) the
redemption or conversion of such shares of Series C Preferred Stock, and if not
paid upon liquidation, redemption or conversion, the amount of all such accrued
dividends and interest payments shall become an unsecured obligation of the
Corporation, bearing interest at the per annum rate of 100 basis points over The
Wall Street Journal Prime Rate as of the last business day prior to such
liquidation, redemption or conversion and such interest shall be payable on the
first day of each month of January, April, July and October if, at the time of
payment (i) all dividends and interest accrued on or declared with respect to
the Series A Preferred Stock and the Series B Preferred Stock have been fully
paid, and (ii) funds for the full payment of such quarterly dividend on all
shares of Series C Preferred Stock then outstanding are legally available
therefor under the laws of the State of Maryland as then in effect.

                           (c) Cancellation of Accrued Dividends. All accrued
dividends and unpaid interest shall be canceled and no longer be payable in the
event the Company consummates a Qualified Public Offering on or before August
30, 1998 at a price per share of not less than the weighted average price paid
or to be paid by the Series C Preferred Stockholder for all shares of Series C
Preferred Stock then 


                                       66


<PAGE>


outstanding or subject to the Option, plus all accrued but unpaid dividends and
interest thereon.

                           (d) Reduction of Capital. If at any time when a
dividend on shares of Series C Preferred Stock would otherwise be payable (i)
funds for the full payment of such dividend are not then legally available
therefor under the laws of the State of Maryland as then in effect as applied to
the then effective capitalization of the Corporation, and (ii) funds for the
payment of such dividend would be legally available if the stated capital
accounts of the Corporation were reduced or capital surplus was revalued, then,
in such event, the Board shall reduce the stated capital at least to the extent
necessary to declare and pay such dividend or cause a revaluation of capital
surplus if such reduction of capital or valuation of surplus would be
permissible under the laws of the State of Maryland as then in effect and unless
the exercise of the Board's fiduciary duty prevents such reduction.

                           (e) Limitation on other Dividends; Payments. So long
as any shares of Series C Preferred Stock remain outstanding, (i) no dividends
shall be declared or paid upon, nor shall any dividend or other distribution be
made with respect to, any shares of any other class or series of stock or equity
interest of the Corporation or any Subsidiary, other than the Series A Preferred
Stock or Series B Preferred Stock, without the consent of each of the Series C
Preferred Stock Directors (or the sole Series C Preferred Stock Director, when
applicable), and (ii) no shares of any class of stock or equity interest of the
Corporation or any Subsidiary other than the shares of Series C Preferred Stock,
Series B Preferred Stock and Series A Preferred Stock shall be redeemed,
retired, purchased or otherwise acquired by the Corporation, except purchases of
the Corporation's interests in a Subsidiary at the time of its organization.
Notwithstanding the foregoing, the Corporation may (i) effect Permitted
Redemptions pursuant to Section A.5; and (ii) may redeem shares of capital stock
of or equity interests in any wholly-owned Subsidiary.

                   3.      REDEMPTION.

                           (A) OPTIONAL REDEMPTION BY HOLDERS. If, without the
approval of the Series C Preferred Stock Directors, the Corporation elects to
consummate either (1) an initial underwritten public offering of the
Corporation's equity securities, (2) a merger, consolidation or similar
combination transaction in which the Company is not the survivor, or (3) a sale,
transfer or other disposition by the Corporation of all or substantially all of
the Corporation's assets, whether by asset or stock sale or otherwise, at a
price per share equal to or less than the weighted average price paid or to be
paid by the Series C Preferred Stockholder for all shares of Series C Preferred
Stock then outstanding or subject to the Option, plus all accrued but unpaid
dividends and interest thereon, then the Corporation shall give notice of such
election to each holder of Series C Preferred Stock at least 30 (30) days prior
to the date such action is 

                                       67


<PAGE>



to be effective, and the holders of Series C Preferred Stock shall be entitled,
by delivery of a written notice to the Corporation at the principal office of
the Corporation not less than twenty-one (21) days prior to the date such action
is to be effective, to request the Corporation to redeem, and the Corporation
shall redeem out of any funds legally available therefor, all (but not less than
all) of the then issued and outstanding shares of Series C Preferred Stock then
held by the holders requesting redemption, at an amount per share of Series C
Preferred Stock outstanding equal to the greater of (A) the then fair market
value of such share (including, for purposes of calculating such fair market
value, the sum of all accumulated and unpaid interest and dividends on such
share of Series C Preferred Stock, whether or not such dividends have been
declared by the Corporation to the date such share is actually redeemed) or (B)
the weighted average price paid by the Series C Preferred Stockholder for each
share of Series C Preferred Stock then outstanding, plus all accrued but unpaid
dividends and interest thereon, whether or not such dividends have been declared
by the Corporation to the date such share is actually redeemed. To the extent
that net cash proceeds are received by the Corporation as the result of the
taking of such action, (i) the Corporation shall pay any redemption price in
cash to the holders of Series C Preferred Stock, such cash to be paid pro rata
among the holders of Series C Preferred Stock requesting such redemption (with
such redemption being a condition precedent to the Corporation's receipt of such
net proceeds) upon the occurrence of such action (a "Series C Redemption Date").
To the extent that such net cash proceeds received by the Corporation as a
result of taking such action are insufficient to enable the Corporation to make
full payment in cash, the Corporation may pay the balance due with respect to
the redemption of such shares within 180 days of such request.


                           (B) MANDATORY REDEMPTION BY THE CORPORATION. Upon the
occurrence of any Event of Non-Compliance (as defined in Section D.6), the
Corporation shall redeem all, but not less than all, of the shares of Series C
Preferred Stock then held by each holder at an amount per share of Series C
Preferred Stock outstanding equal to the greater of (A) the then fair market
value of such share (including, for purposes of calculating such fair market
value, the sum of all accumulated and unpaid interest and dividends on such
share of Series C Preferred Stock, whether or not such dividends have been
declared by the Corporation to the date such share is actually redeemed) or (B)
the weighted average price paid by the Series C Preferred Stockholder for each
share of Series C Preferred Stock then outstanding, plus all accrued but unpaid
dividends and interest thereon, within ten (10) business days after the
occurrence of such Non-Compliance. Any such redemption shall not be in lieu of
or in any way limit any other rights which such holders may have (at law or in
equity) in connection with the event giving rise to their right of redemption.

                            (C)     GENERAL PROVISIONS FOR REDEMPTIONS.


                                       68


<PAGE>


                           (i) Series C REDEMPTION PRICE. Each amount payable by
the Corporation pursuant to Section D.3 hereof is referred to as the "Series C
Redemption Price".

                           (ii) EFFECT OF REDEMPTION. Provision for payment of
the Series C Redemption Price for shares of Series C Preferred Stock having been
made by the Corporation, and for so long as there shall be no default in the
payment of deferred portions of the Series C Redemption Price, then (A) the
shares of Series C Preferred Stock designated for redemption in any notice shall
not be entitled to any dividends accruing after the specified Redemption Date,
and (B) on such Redemption Date all rights of the respective holders of such
shares, as stockholders of the Corporation by reason of the ownership of such
shares of Series C Preferred Stock, shall cease, except the right to receive the
Redemption Price upon presentation and surrender of the respective certificates
representing such shares.

                           (iii) RETIREMENT OF SHARES. Shares of Series C
Preferred Stock that have been redeemed, purchased or otherwise acquired by the
Corporation shall be retired and may not be reissued.

                           (iv) SUBORDINATION OF SERIES C REDEMPTION PRICE. If,
at the time the Series C Redemption Price is payable to the holders of the
Series C Preferred Stock, the Series A Redemption Price and/or Series B
Redemption Price is also payable to the holders of the Series A Preferred Stock
or Series B Preferred Stock or the Series A Preferred Stock or Series B
Preferred Stock has been designated for redemption pursuant to the terms hereof,
no payment shall be made to the holders of Series C Preferred Stock in respect
of the Series C Redemption Price unless and until the Series A Redemption Price
and Series B Redemption Price shall have been paid in full to the holders of the
Series A Preferred Stock and Series B Preferred Stock.

                           (v) EFFECT OF LEGAL RESTRICTIONS ON PAYMENT. If the
Redemption Price for any such shares cannot be paid in full because the
Corporation is prohibited by law from making such payment, then those funds that
are legally available will be used to pay (ratably if necessary) accrued but
unpaid interest, then accrued but unpaid dividends, and then to redeem the
maximum possible number of shares of Series C Preferred Stock ratably among the
holders thereof determined by multiplying the total number of shares of Series C
Preferred Stock to be redeemed times a fraction, the numerator of which shall be
the total number of such shares then held by each such holder and the
denominator of which shall be the total number of such shares then outstanding.
The shares of Series C Preferred Stock not redeemed shall remain outstanding and
be entitled to all rights and preferences provided herein; provided, however, at
any time thereafter when additional funds of the Corporation are legally
available for the redemption of such shares of Series C Preferred Stock, such
funds will be used, at the end of the next succeeding fiscal quarter, to redeem
the balance of such shares, or such portion thereof for which funds are then
legally available. If fewer 


                                       69


<PAGE>


than the total number of shares of Series C Preferred Stock represented by any
certificate are redeemed, a new certificate representing the number of
unredeemed shares will be issued to the holder thereof without cost to such
holder within three business days after surrender of the certificate
representing the redeemed shares of Series C Preferred Stock.

                           (vi) RESTRICTIONS ON CORPORATE ACTIONS. If the
Corporation for any reason fails to redeem any shares of Series C Preferred
Stock in accordance with this Section D.3 on or prior to the Redemption Date
specified herein, then, notwithstanding anything to the contrary contained in
these Articles of Incorporation, the Corporation may not incur any Indebtedness
(unless the proceeds of such incurrence of Indebtedness are used to make all
overdue redemption payments in respect of the Series C Preferred Stock,
including payments of accrued but unpaid dividends or interest) without the
prior written consent of the holders of the Series C Preferred Stock voting
separately as a class; provided, however, that, subject to the restriction set
forth in Section D.1(c)(i), the Corporation may incur Indebtedness without the
aforesaid approval if (A) the proceeds of such borrowing are used to pay
obligations of the Corporation arising in the ordinary course of business as
they become due and payable, or otherwise to maintain the operations of the
Corporation at the then current level and not to expand the operation of the
Corporation in any material respect, whether through expansion or enhancement
of, or addition, to the Corporation's then current activities, facilities,
equipment or other capital assets, or otherwise, (B) the Corporation provides
prior written notice of such borrowing to all holders of Series C Preferred
Stock, which notice shall include a statement of the intended use of the
proceeds of such borrowing, and (C) promptly upon request therefor, the
Corporation shall provide to any holder of Series C Preferred Stock a
certificate signed by the President and Chief Financial Officer of the
Corporation certifying as to the allocation and use of the proceeds of any such
borrowing.

                           (vii) MULTIPLE HOLDERS OF SERIES C PREFERRED STOCK.
If the Series C Preferred Stock is at any time held by more than one person or
entity, the request for redemption pursuant to this Section D.3 by the holders
of at least fifty-one percent (51%) of the then issued and outstanding shares of
Series C Preferred Stock shall constitute the request for redemption by the
holders of all of the then issued and outstanding shares of Series C Preferred
Stock and all such holders of Series C Preferred Stock shall redeem their shares
of Series C Preferred Stock pursuant to this Section D.3 upon the receipt of
notice from holders of at least fifty-one percent (51%) of the then issued and
outstanding shares of Series C Preferred Stock.

                           (viii) APPRAISAL. Within fourteen (14) days of any
written request of any holder of shares of Series C Preferred Stock from time to
time, the fair market value of the Series C Preferred Stock shall be determined
by an appraiser or appraisers according to the terms and procedures of Section
B.3(d)(viii), except that all 


                                       70


<PAGE>


references shall be to Series C Preferred Stock and Stockholders rather than
Series A Preferred Stock and Stockholders.

                   4.      CONVERSION RIGHTS.

                            (a)     OPTIONAL CONVERSION BY HOLDER.

                           (i) General Provisions. All, but not less than all,
of the issued and outstanding shares of Series C Preferred Stock shall be
convertible, without the payment of any additional consideration, into shares of
Class C Common Stock, at the option of the holders of the shares of Series C
Preferred Stock, at any time. Each such share of Series C Preferred Stock shall
be convertible at such time into one fully-paid and nonassessable share of Class
C Common Stock, subject to adjustment as provided in Section D.4.(e) below (the
"Series C Conversion Rate"). The holders of shares of Series C Preferred Stock
requesting conversion of shares into shares of Class C Common Stock shall send a
written notice to the Corporation, at the principal office of the Corporation,
requesting such conversion. The holders shall, as soon thereafter as
practicable, deliver the certificates therefor, duly endorsed for transfer, at
the principal office of the Corporation or any transfer agent for the Series C
Preferred Stock. The Corporation shall, as soon as practicable thereafter, issue
and deliver to the holders a certificate or certificates for the number of such
shares of Class C Common Stock to which the holders shall be entitled, a check
payable to the holders in the amount of any cash in lieu of issuance of any
fractional share, and the amount of any cumulative dividends and interest
accrued but unpaid on such shares (unless, and to the extent, the Corporation is
entitled to cancel accrued dividends as herein provided). The conversion shall
be deemed to have been made immediately prior to the close of business on the
date of receipt of the notice. The persons entitled to receive the shares of
Class C Common Stock issuable upon such conversion shall be treated for all
purposes as the record holder or holders of such shares of Class C Common Stock
on such date, and the shares of Series C Preferred Stock converted shall
immediately be canceled and may not be reissued.

                           (ii) Multiple Holders of Series C Preferred Stock. If
the Series C Preferred Stock is at any time held by more than one person or
entity, the request for conversion pursuant to this Section D.4 by the holders
of at least fifty-one percent (51%) of the then issued and outstanding shares of
Series C Preferred Stock shall constitute the request for conversion by the
holders of all of the then issued and outstanding shares of Series C Preferred
Stock and all such holders of Series C Preferred Stock shall convert their
shares of Series C Preferred Stock pursuant to this Section D.4 upon the receipt
of notice from holders of at least fifty-one percent (51%) of the then issued
and outstanding shares of Series C Preferred Stock.


                                       71


<PAGE>


                           (b) AUTOMATIC CONVERSION. If the holders of Series C
Preferred Stock have not earlier exercised their rights to require the
Corporation to redeem their shares of Series C Preferred Stock pursuant to the
provisions of Section D.3.(a), all of the outstanding shares of Series C
Preferred Stock shall, together with all other then outstanding shares of the
Corporation's preferred stock or other capital stock with rights to convert into
shares of Common Stock, be converted into fully-paid and nonassessable shares of
Class C Common Stock at the Series C Conversion Rate upon the earlier to occur
of the closing or other consummation of (i) any Qualified Public Offering, (ii)
any Non-Qualified Public Offering, (iii) any combination, consolidation or
merger where the Corporation is not the survivor, or (iv) any sale, exchange or
other disposition of all or substantially all of the Corporation's assets,
whether by asset or stock sale or otherwise. Shares of Class C Common Stock
received pursuant to this Section 4.(b) shall be subject to the provisions of
Article IV, Section A.4 in the event of a Qualified Public Offering or
Non-Qualified Public Offering, and shall thereupon immediately be reclassified
as shares of Class A Common Stock. At least twenty (20) days prior written
notice of the date fixed and place designated for conversion shall be sent by
first class mail, postage prepaid, to the address of each holder of shares of
Series C Preferred Stock as shown in the records of the Corporation. On or
before the date fixed for conversion, each holder of shares of Series C
Preferred Stock shall surrender the certificates representing such shares to the
Corporation at the place designated in such notice and shall thereafter receive
certificates for the number of full shares of Common Stock to which such holder
is entitled. Until such time as holders of certificates theretofore representing
shares of Series C Preferred Stock have surrendered them for exchange as
provided herein, no dividends shall be paid with respect to any shares
represented by such certificates and no payment for fractional shares shall be
made.

                           (c) NO FRACTIONAL SHARES. No fractional shares of
Common Stock shall be issued upon conversion of shares of Series C Preferred
Stock. In lieu of any fractional share, the Corporation shall pay a cash
adjustment in respect of such fractional interest equal to the fair market value
of such fractional interest as determined by the Board.

                           (d) PAYMENT OF DIVIDENDS AND INTEREST. At the time of
the conversion of any shares of Series C Preferred Stock, and after payment in
full by the Corporation of all amounts of interest and cumulative dividends
accrued but unpaid with respect to Series A Preferred Stock and Series B
Preferred Stock, the Corporation shall, to the extent not canceled pursuant to
Section 2(c), pay to the holder of such shares of Series C Preferred Stock the
sum of all interest and cumulative dividends accrued but unpaid and then due
with respect to such Series C Preferred Stock, whether or not such dividends
shall have been declared by the Corporation to the date of conversion.


                                       72


<PAGE>



                           (e) ADJUSTMENTS; ANTIDILUTION. The number of shares
of Class C Common Stock issuable upon the conversion of the Series C Preferred
Stock shall be subject to adjustment from time to time upon the happening of
certain events as follows:

                           (i) DIVIDENDS, SPLITS. If the Corporation declares a
dividend payable in its shares of its Common Stock, splits any of its Common
Stock or combines any of its outstanding shares of Common Stock into a smaller
number, then the number of fully-paid and nonassessable shares of Class C Common
Stock into which each share of Series C Preferred Stock may be converted shall
forthwith be adjusted by multiplying one (1) by a fraction (A) the numerator of
which shall be the total number of outstanding shares of Common Stock
immediately after such dividend, stock split or combination, and (B) the
denominator of which shall be the total number of outstanding shares of Common
Stock immediately prior to such dividend, stock split or combination.

                           (ii) REORGANIZATION, RECLASSIFICATION. In the event
of a reorganization, share exchange, or reclassification, other than a change in
par value, or from par value to no par value, or from no par value to par value
or a transaction described in subsection (iii) or (iv) below, each share of
Series C Preferred Stock shall, after such reorganization, share exchange or
reclassification, be convertible into the kind and number of shares of stock or
other securities or property of the Corporation to which the holder of Series C
Preferred Stock would have been entitled if the holder had held the Class C
Common Stock issuable upon conversion of its Series C Preferred Stock
immediately prior to such reorganization, share exchange, or reclassification,
or to which the Series C Preferred Stock is actually entitled, but not both.

                           (iii) CONSOLIDATION, MERGER, SALE OF ASSETS. In the
event of a merger or consolidation or sale, exchange or other disposition of
all, or substantially all of the Corporation's assets, to which the Corporation
is a party, each share of Series C Preferred Stock shall, after such merger or
consolidation, be convertible into the kind and number of shares of stock and/or
other securities, cash or other property to which the holder of such share of
Series C Preferred Stock would have been entitled if the holder had held the
Class C Common Stock issuable upon conversion of its shares of Series C
Preferred Stock immediately prior to such consolidation or merger or sale of
assets, or to which the Series C Preferred Stock is actually entitled, but not
both.

                           (iv) CERTAIN ISSUANCES OF ADDITIONAL SHARES OF COMMON
STOCK. If the Corporation shall issue any additional shares of Common Stock --
other than securities to be issued (i) to the public pursuant to any Qualified
Public Offering or Non-Qualified Public Offering, (ii) to officers, directors,
or employees of the Corporation as part of a stock option plan, restricted stock
plan, employee stock purchase plan, employment agreement, or other employee
stock plan or agreement, implemented by the Board, (iii) upon conversion of any
shares of the Series A Preferred Stock or Series B Preferred Stock or the
exercise of any warrant to purchase shares of Common Stock 


                                       73

<PAGE>


held by the holder of any Series A Preferred Stock or Series B Preferred Stock,
or(iv) to the LP pursuant to Article XIV of the Practice Participation Agreement
in respect of the issuance of Medical Holdings Limited Partnership of the
Limited Partner Interests (or options to purchase such Interests) from and after
the time that more than sixty-six (66) but less than one hundred (100)
physicians hold such Limited Partner Interests (or options to acquire such
Interests) directly or indirectly through their professional corporations, or
(v) to any physician or physician group in consideration for the acquisition of
physician practices (or other contracting arrangements) approved by the Board of
Directors -- for a consideration per share of Common Stock less than the
"conversion price," as adjusted or as previously adjusted, in effect on the date
immediately prior to such issuance, then and in such event, such conversion
price shall be adjusted, concurrently with such issuance, to a price equal to
the quotient obtained by DIVIDING:

                                    (1) an amount equal to (x) the sum of (A)
                  the total number of shares of Common Stock outstanding
                  immediately prior to such issuance or sale, plus (B) the total
                  number of shares of Common Stock issuable upon exercise of all
                  options, warrants and other rights convertible or exchangeable
                  for, or evidencing the right to purchase shares of, Common
                  Stock outstanding immediately prior to such issuance or sale,
                  multiplied by (C) the conversion price in effect immediately
                  prior to such issuance or sale, plus (y) the consideration, if
                  any, received or deemed to be received by the Corporation upon
                  such issuance or sale; BY

                                    (2) the sum of (A) the total number of
                  shares of Common Stock outstanding immediately after such
                  issuance or sale, plus (B) the total number of shares of
                  Common Stock issuable upon exercise of all options, warrants
                  and other rights convertible or exchangeable for, or
                  evidencing the right to purchase shares of, Common Stock
                  outstanding immediately after such issuance or sale.

For purposes of this Section D.4, the conversion price per share shall be equal
to the weighted average price paid or to be paid by the Series C Preferred
Stockholder for each share of Series C Preferred Stock then outstanding or
subject to the Option, plus all accrued but unpaid dividends and interest
thereon.

No adjustment of the conversion price shall be made under this Section
D.4.(e)(iv) upon the issuance of any additional shares of Common Stock that are
issued pursuant to the exercise of any warrants, options or other subscription
or purchase rights or pursuant to the exercise of any conversion or exchange
rights in any convertible securities if any such adjustments shall previously
have been made upon the issuance 


                                      74


<PAGE>


of any such warrants, options or other rights or upon the issuance of any
convertible securities (or upon the issuance of any warrants, options or any
rights therefor).

Notwithstanding the foregoing provisions of this Section D.4.(e)(iv) and the
provisions of Sections D.4.(e)(v) and D.4.(e)(vi), the anti-dilution protection
afforded by this Section D.4.(e)(iv) shall apply to issuances of (A) shares of
the Company's capital stock, (B) warrants, options or other rights to subscribe
for or purchase any additional shares of capital stock, or (C) securities
convertible into such stock, made to (1) founders, officers, directors and
employees of the Company in excess of the equivalent of 1,486,000 shares of
Common Stock at purchase, exercise or conversion prices less than 80% of the
fair market value of a share of Common Stock at the time of issuance and (2)
physicians in connection with acquisition transactions and other contracting
arrangements at purchase, exercise or conversion prices less than 80% of the
fair market value of a share of Common Stock at the time of issuance. For
purposes of this Section, the fair market value of a share of the Common Stock
as of September 4, 1996 shall be equal to $17.50.

                           (v) ISSUANCE OF WARRANTS, OPTIONS OR OTHER RIGHTS. If
the Corporation at any time shall issue any warrants, options or other rights to
subscribe for or purchase any additional shares of Common Stock and the price
per share for which additional shares of Common Stock may at any time thereafter
be issuable pursuant to such warrants, options or other rights shall be less
than the conversion price per share in effect immediately prior to such
issuance, then such issue shall be deemed an issuance (as of the date of issue
of such warrants, options or other rights) of the total maximum number of shares
of Common Stock issuable pursuant to such warrants, options or other rights, and
the conversion price shall thereupon be adjusted as provided in Section
D.4.(e)(iv) hereof on the basis that the aggregate consideration for the
additional shares of Common Stock issuable pursuant to such warrants, options or
other rights, plus the minimum consideration to be received by the Corporation
for the issuance of additional shares of Common Stock pursuant to such warrants,
options, or other rights shall be deemed to be the consideration received by the
Corporation for the issuance of such warrants, options, or other rights.

                           (vi) CERTAIN ISSUANCES OF CONVERTIBLE SECURITIES. In
case the Corporation shall issue any securities convertible into Common Stock
and the consideration per share for which such additional shares of Common Stock
may at any time thereafter be issuable pursuant to the terms of such convertible
securities shall be less than the conversion price per share in effect
immediately prior to such issuance, then upon such issuance of such securities
the conversion price shall be adjusted as provided in Section D.4.(e)(iv) hereof
on the basis that (i) the maximum number of additional shares of Common Stock
necessary to effect the conversion or exchange of all such convertible
securities shall be deemed to have been issued as of the date of issuance of
such convertible securities, and (ii) the aggregate consideration for such


                                      75


<PAGE>


maximum number of additional shares of Common Stock plus the minimum
consideration received by the Corporation for the issuance of such additional
shares of Common Stock pursuant to the terms of such convertible securities
shall be deemed to be the consideration received by the Corporation for the
issuance of such convertible securities. No adjustment of the conversion price
shall be made under this subsection upon the issuance of any convertible
securities which are issued pursuant to the exercise of any warrants, options or
other subscription or purchase rights therefor, if any such adjustment shall
previously have been made upon the issuance of such warrants, options or other
rights pursuant to Section D.4.(e)(v) hereof.

                           (vii) ADJUSTMENT OF SERIES C CONVERSION RATE. Upon
each adjustment of the conversion price under the provisions of this Section
D.4.(e), the conversion rate shall be adjusted to an amount determined by
dividing the conversion price then in effect by such adjusted conversion price.

                           (viii) OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS
UNDER THIS SECTION. The following provisions will be applicable to the making of
adjustments in conversion prices hereinabove provided in this Section D.4.(e):

                           (1) COMPUTATION OF CONSIDERATION. To the extent that
any additional shares of Common Stock or any convertible securities or any
warrants, options or other rights to subscribe for or purchase any additional
shares of Common Stock or any convertible securities shall be issued for cash
consideration, the consideration received by the Corporation therefor shall be
deemed to be the amount of the cash received by the Corporation therefor, or, if
such additional shares of Common Stock or convertible securities are offered by
the Corporation for subscription, the subscription price. To the extent that
such issuance shall be for a consideration other than cash, then the amount of
such consideration shall be deemed to be the fair value of such consideration at
the time of such issuance as determined in good faith by the Corporation's Board
after receipt of a fairness opinion, appraisal or similar independent
third-party advice determined by a person or entity jointly selected by the
Series C Preferred Directors, the Series A Preferred Directors, the Series B
Preferred Directors and the other directors pursuant to procedures substantially
similar to those contained in Section 6 of the Stockholders Agreement. The
consideration for any additional shares of Common Stock issuable pursuant to any
warrants, options or other rights to subscribe for or purchase the same shall be
the consideration received by the Corporation for issuing such warrants, options
or other rights, plus the additional consideration payable to the Corporation
upon the exercise of such warrants, options or other rights. The consideration
for any additional shares of Common Stock issuable pursuant to the terms of any
convertible securities shall be the consideration paid or payable to the
Corporation in respect of the subscription for or purchase of such convertible
securities, plus the additional consideration, if any, payable to the
Corporation upon the exercise of the right of conversion or exchange in such


                                       76


<PAGE>


convertible securities. In case of the issuance at any time of any additional
shares of Common Stock or convertible securities in payment or satisfaction of
any dividend upon any class of stock preferred as to dividends in a fixed
amount, the Corporation shall be deemed to have received for such additional
shares of Common Stock or convertible securities a consideration equal to the
amount of such dividend so paid or satisfied.

                           (2) READJUSTMENT OF CONVERSION PRICE. Upon the
expiration of the right to convert or exchange any convertible securities, or
upon the expiration of any rights, options or warrants, without conversion,
exchange or exercise, the issuance of which convertible securities, rights,
options or warrants effected an adjustment in the conversion price, such
conversion price shall forthwith be readjusted and thereafter be the price which
it would have been (but reflecting any other adjustments in the conversion price
made pursuant to the provisions of this Section D.4.(e) after the issuance of
such convertible securities, rights, options or warrants) had the adjustment of
the conversion price made upon the issuance or sale of such convertible
securities or issuance of rights, options or warrants been made on the basis of
the issuance only of the number of additional shares of Common Stock actually
issued upon conversion or exchange of such convertible securities, or upon the
exercise of such rights, options or warrants, and thereupon only the number of
additional shares of Common Stock actually so issued, if any, shall be deemed to
have been issued and only the consideration actually received by the Corporation
(computed as set forth in subsection D.4.(e)(viii)(1) hereof) shall be deemed to
have been received by the Corporation. If the purchase price provided for in any
such rights, options or warrants, or the additional consideration (if any)
payable upon the conversion or exchange of any convertible securities, or the
rate at which any convertible securities are convertible into or exchangeable
for shares of Common Stock changes at any time (other than under or by reason of
provisions designed to protect against dilution), the conversion price in effect
at the time of the change shall be adjusted to the conversion price that would
have been in effect at such time had such rights, options, warrants or
convertible securities still outstanding provided for such changed purchase
price, additional consideration or conversion rate, as the case may be, at the
time initially granted, issued or sold.

                           (3) OTHER ACTION AFFECTING COMMON STOCK. If the
Corporation shall take any action affecting the outstanding number of shares of
Common Stock, other than an action described in any of the foregoing subsections
4(e)(i) to (vii) hereof, inclusive, which in the opinion of the Corporation's
Board would have a materially adverse effect upon the rights of the holders of
the Series C Preferred Stock, the conversion price shall be adjusted in such
manner and at such time as the Board may determine to be equitable in the
circumstances.

                           (ix) NOTICES OF ADJUSTMENTS. Whenever the conversion
rate and conversion price is adjusted as herein provided, an officer of the
Corporation shall 


                                       77


<PAGE>


compute the adjusted conversion rate and conversion price in accordance with the
foregoing provisions and shall prepare a written instrument setting forth such
adjusted conversion rate and conversion price and showing in detail the facts
upon which such adjustment is based, and such written instrument shall promptly
be delivered to the record holders of the Series C Preferred Stock, who shall
approve such conversion rates and prices within 30 days of receipt. If holders
of Series C Preferred Stock do not object in writing during such 30 day period,
they shall be deemed to have approved such conversion rates and prices for all
purposes hereof.

                           (f)RESERVATION OF SHARES. The Board shall at all
times reserve and keep available, out of its authorized but unissued shares of
Class C Common Stock, solely for the purpose of effecting the conversion of the
shares of Series C Preferred Stock, the full number of shares of Class C Common
Stock deliverable by the Corporation upon the conversion of all shares of Series
C Preferred Stock from time to time outstanding and otherwise issuable under

                   5.      LIQUIDATION RIGHTS.

                           (a) Upon any liquidation, dissolution or winding up
of the affairs of the Corporation, whether voluntary or involuntary, the holders
of shares of the Series C Preferred Stock shall be entitled to receive out of
the assets of the Corporation available for distribution to stockholders, before
any distribution or payment shall be made in respect of the holders of shares of
Common Stock or any other class or series of stock ranking junior to the Series
C Preferred Stock, a liquidating distribution in an amount equal to $17.50 per
share of Series C Preferred Stock issued pursuant to the Stock Purchase
Agreement which is then outstanding and $20.00 per share of Series C Preferred
Stock issued pursuant to the Option Agreement which is then outstanding, plus
all accrued but unpaid dividends and interest thereon; provided, however, that
the amount of cash payable by the Corporation shall not exceed the amount of
cash paid to the Corporation by all holders of such shares with respect to the
purchase of such shares, including the payment of any interest with respect
thereto, through and including the date of liquidation; and provided further,
however, that no liquidating distribution shall be paid in respect of Series C

Preferred Stock and Series B Preferred Stockholders as a liquidating
distribution and to holders and guarantors of senior indebtedness of the
Corporation contemplated in the Operating Plan shall have been fully paid. The

or winding up of the affairs of the Corporation resulting in any distribution of
assets to stockholders.

                           (b) If, upon any such liquidation, dissolution or
winding up of the affairs of the Corporation, the assets of the Corporation to
stockholders shall be insufficient to permit the payment in full to the holders
of Series C Preferred Stock of the amounts to which they are entitled, then all
of such available assets shall be distributed to the holders of shares of Series
C Preferred Stock ratably in proportion to the liquidation payment otherwise due
under Section D.5.(a) to each such holder and no amounts shall be distributed in
respect of any other share of capital stock of the Corporation other than Series
A Preferred Stock and Series B Preferred Stock until all amounts distributable
to holders of Series C Preferred Stock have been distributed.

                           (c) The purchase or redemption by the Corporation of
stock of any class, in any manner permitted by law, shall not for the purpose of
this Section D.5. be regarded as a liquidation, dissolution or winding up of the
Corporation. Neither the consolidation nor merger of the Corporation with or
into any other corporation or corporations, nor the sale or transfer by the
Corporation of all or any part of its assets shall be deemed to be a
liquidation, dissolution or winding up of the Corporation for the purpose of
this Section D.5.

appearing on stock certificates may be facsimiles if each such certificate is
authenticated by the manual signature of an officer of a duly authorized
transfer agent. Stock certificates shall be in such form, not inconsistent with
law and the Charter, as shall be approved by the Board of Directors. In case any
officer of the Corporation who has signed any certificate ceases to be an

registrar, upon surrender and cancellation of a certificate or certificates for
a like number of shares.

SECTION 3.  RECORD DATES FOR DIVIDENDS AND STOCKHOLDERS'

                  The Board of Directors may fix a date not exceeding 90 days

any date for the allotment of rights, as a record date for the determination of
the stockholders entitled to notice of and to vote at such meeting, or entitled
to receive such dividends or rights, as the case may be, and only stockholders
of record on such date shall be entitled to notice of and to vote at such
meeting or to receive such dividends or rights, as the case may be. In the case
of a meeting of stockholders, the record date shall be fixed not less than ten
days prior to the date of the meeting.

                  In case any certificate of stock is lost, stolen, mutilated or
destroyed, the Board of Directors may authorize the issuance of a new
certificate in place thereof upon such indemnity to the Corporation against loss
and such other terms and conditions as it may deem advisable. The Board of
Directors may delegate such power to any officer or officers of the Corporation
or to any transfer agent or registrar of the Corporation; but the Board of
Directors, such officer or officers or such transfer agent or registrar may, in
their discretion, refuse to issue such new certificate save upon the order of
some court having jurisdiction.

                  NOW, THEREFORE, in consideration of the mutual covenants and

                  1.       RECITALS; DEFINITIONS.

                  (a)      RECITALS. The foregoing recitals are made a part of
this Agreement.

                  (b)      CERTAIN DEFINITIONS.

                  "CHANGE IN CONTROL" shall mean the earlier to occur of the
following: (i) a liquidating distribution to DHS' stockholders (or similar
event); (ii) a contribution, consolidation or merger where DHS is not the
survivor; (iii) any sale, exchange or other disposition of all, or substantially
all, of DHS'

<PAGE>

assets; or (iv) any public offering of DHS' securities at a company value of at
least $25,000,000 with proceeds to DHS of at least $15,000,000.

Amendment and Restatement of DHS filed with the Maryland State Department of
Assessments and Taxation and effective on September 4, 1996

                  (c) OTHER DEFINED TERMS. When used in this Agreement with its
initial letter capitalized, a word that is not defined in this Section 1 shall
have the meaning set forth elsewhere in this Agreement. When a word used in this
Agreement with its initial letter capitalized is not defined in this Agreement,
such word shall have the meaning set forth in the Definition Appendix attached
to this Agreement as Appendix A.

                  2. STOCK, WARRANTS AND OPTIONS COVERED; ADDITIONAL PARTIES.
Except as otherwise provided herein, all of the provisions of this Agreement
shall apply to, and the term "Stock" shall include, the Stock and all other
shares of capital stock and rights, including warrants and options, to acquire
shares of capital stock and all other equity securities now owned or which may
be issued hereafter to the Stockholders in consequence of any additional
issuance, purchase, exchange or reclassification of shares, corporate
reorganization, or any other form of recapitalization, consolidation, merger,
share split, share dividend, or which are acquired by Stockholders in any other
manner. For purposes of this Agreement, the term "Stock" shall include (i)
beneficial interests held by any beneficiary in any trust permitted to be a
transferee hereunder, (ii) that certain Stock Warrant No. 1 executed and
delivered on November 28, 1995 by DHS to the Series B Investor granting to the
Series B Investor the right to acquire Eighty Eight Thousand Eight Hundred
Eighty Nine (88,889) shares of the Class A Common Stock of the Company (the
"WARRANT"), and (iii) the option of the Series C Investor to purchase Five
Hundred Thousand (500,000) shares of Series C Preferred Stock from DHS pursuant
to the Option Agreement dated as of September 4, 1996 between DHS and the Series
C Investor (the "OPTION"). The parties hereto acknowledge and agree that upon
conversion of shares of Convertible Preferred Stock into shares of Class C
Common Stock all references to "Stock" and all references to "Convertible
Preferred Stock" herein shall include all such shares of Class C Common Stock,
and all references to "holders of Convertible Preferred Stock" shall include
"holders of Class C Common Stock." DHS acknowledges and agrees that it will not
issue any additional shares of its capital stock (or options) to any person or
entity which is not a party to this Agreement without requiring, as a condition
precedent to such issuance, that such person or entity execute a counterpart to
this Agreement (provided that non-executive employees of DHS to whom shares of
capital stock are issued pursuant to any employment agreement or any stock
option, stock purchase or similar plan of DHS shall not be required to execute
this Agreement so long as DHS, as a condition of such issuance, retains rights
to repurchase such shares of capital stock under substantive terms

                                    
                                       -3-
<PAGE>

and conditions consistent with those granted to DHS herein), and any member of
DHS' executive management team who is granted shares (or options) shall be
deemed a "Management Stockholder" for purposes hereof.

                  3. PURCHASE AND SALE. DHS agrees to purchase and redeem, and
each Stockholder agrees to sell and transfer, the Stock in the manner and upon
the terms provided in this Agreement. No purchase, sale, gift, endorsement,
assignment, transfer, pledge, encumbrance or other disposition, whether
voluntary, involuntary or by operation of law, including, without limitation,
any transfer pursuant to a divorce decree, of any shares of Stock of any
Stockholder shall be valid and binding except as provided in, and in accordance
with, the terms and conditions of this Agreement. Any purported transfer by any
Stockholder of the Stock or issuance of capital stock by the Company other than
in accordance with this Agreement shall be null and void, and DHS shall refuse
to recognize any such transfer and shall not reflect on its records any change
in record ownership of the Stock pursuant to any such transfer. Any transferee
of the Stock becoming the owner of the Stock in compliance with this Agreement
shall thereafter be deemed a Stockholder. The personal representative of a
deceased Stockholder shall automatically be subject to the terms and conditions
of this Agreement. Notwithstanding the foregoing, the holders of Convertible
Preferred Stock are entitled, pursuant to the terms of the DHS Amended and
Restated Articles, to exercise rights to convert shares of Convertible Preferred
Stock into shares of Class C Common Stock, and to require DHS to purchase shares
of Convertible Preferred Stock under certain circumstances, and no such
conversion or redemption shall give any person any rights under this Agreement.

                  4. DEATH, DISABILITY AND TERMINATION OF EMPLOYMENT OF A
MANAGEMENT STOCKHOLDER; INVOLUNTARY TRANSFERS

                  (a)      GENERAL.

                           (i) Upon the occurrence of the termination of
         employment of any Management Stockholder (except with respect to each
         of Rifkin and Kimmel, the termination of whose employment is governed
         by Section 4(f) hereof) with DHS for any reason, other than an
         "Involuntary Transfer" (as defined below) including, but not limited
         to, death or "disability" (as defined in Section 4(c) below), such
         Management Stockholder or other Stockholder, as the case may be, shall
         sell, and DHS shall purchase, all of the Stock then registered in such
         Stockholder's name at the price provided in Section 4(e) or Section 6
         hereof, as the case may be, and upon the terms provided in Section 7
         hereof.

                           (ii) Upon the occurrence of an "Involuntary Transfer"
         (as defined in Section 4(d) below) of the Stock of any Stockholder (the
         "INVOLUNTARY TRANSFER STOCKHOLDER"), DHS shall have the right, for a

                                       -4-
<PAGE>

         period of thirty (30) days from the date of such occurrence, to
         purchase such Stock by providing written notice to such effect to such
         Involuntary Transfer Stockholder and to any court which has then
         exercised jurisdiction over such Involuntary Transfer Stockholder with
         respect to its Stock, or to any assignee, trustee in bankruptcy or
         successor in interest, as the case may be, and such Involuntary
         Transfer Stockholder shall be obligated if DHS elects to exercise its
         right to purchase such Stock to sell all but not less than all of the
         Stock then registered in such Involuntary Transfer Stockholder's name
         at the price provided in Section 6 hereof and upon the terms provided
         in Section 7 hereof. If DHS elects not to exercise its purchase
         pursuant to this Section 4(a)(ii) within such thirty (30) day period,
         it shall immediately provide written notice to that effect to all of
         the other stockholders (the "NON-INVOLUNTARY TRANSFER STOCKHOLDERS"),
         who shall have the option to purchase, and such Involuntary Transfer
         Stockholder shall be obligated to sell to the extent such option is
         exercised, all of the shares of such Stock at the price provided in
         Section 6 hereof and upon the terms provided in Section 7 hereof. If
         more than one Non-Involuntary Transfer Stockholder desires to so
         purchase, then they shall purchase in such proportions as they may
         agree. In the absence of agreement, each of the Non-Involuntary
         Transfer Stockholders desiring to purchase such stock shall be entitled
         to purchase up to that number of shares of such Stock which is equal to
         the product of his percentage interest of all of the shares of DHS
         Capital Stock then held by such Non-Involuntary Transfer Stockholders
         multiplied by the number of shares of stock available for purchase
         hereunder. The Non-Involuntary Transfer Stockholders shall have the
         right to exercise their respective options for a period of thirty (30)
         days following their receipt of DHS' notice that it has elected not to
         purchase such Stock by providing notice in the manner required of DHS
         as otherwise set forth in this Section 4(a)(ii).

                  (b) FURTHER ASSURANCES. Each Management Stockholder hereby
agrees that he and/or his personal representative, and each trustee of any
permitted trust hereunder, shall be bound to take any and all action necessary
to enable DHS to purchase his Stock pursuant to the provisions of this Section
4.

                  (c) DISABILITY. For purposes of this Section 4, "DISABILITY"
with respect to a Management Stockholder shall have the meaning set forth in
said Management Stockholder's DHS Employment Agreement or other employment
agreement with DHS, and if no such agreement exists, as determined by DHS' Board
of Directors in the exercise of its reasonable discretion.

                  (d) INVOLUNTARY TRANSFERS; PAYMENT. For purposes of this
Section 4, the occurrence of any of the following events shall constitute an
"INVOLUNTARY TRANSFER": (i) if any portion of a Stockholder's Stock is attached
or taken in execution, or (ii) if a Stockholder applies for the benefit of, or
files a case under, any provision of the federal bankruptcy law or any other law
relating

                                       -5-
<PAGE>

to insolvency or relief of debtors, or (iii) if a case or proceeding is brought
against a Stockholder under any provision of the federal bankruptcy law or any
other law relating to insolvency or relief of debtors which is not dismissed
within sixty (60) days after the commencement thereof, or (iv) if a Stockholder
makes an assignment for the benefit of creditors, or (v) if any portion of a
Stockholder's Stock is made subject to a charging order, or (vi) if any portion
of a Management Stockholder's Stock or other Stock held by a natural person is
transferred pursuant to a divorce decree. For purposes of this Section 4(d), the
occurrence of any of the foregoing events described in Sections 4(d)(i) through
(v) above, (A) with respect to the General Partner of the LP, shall constitute
an Involuntary Transfer with respect to the LP of the Class B Common Stock, (B)
with respect to the Series A Investor, shall constitute an Involuntary Transfer
of the Series A Preferred Stock or the Class C Common Stock, as the case may be,
(C) with respect to the Series B Investor, shall constitute an Involuntary
Transfer of the Series B Preferred Stock, the Warrant or the Class C Common
Stock, as the case may be, and (D) with respect to the Series C Investor, shall
constitute an Involuntary Transfer of the Series C Preferred Stock, the Option
or the Class C Common Stock, as the case may be. If any Stockholder has actual
knowledge of an Involuntary Transfer by a Stockholder of his or its Stock, such
Stockholder shall give written notice to such effect to DHS, and the giving of
such written notice shall constitute the occurrence of such event for purpose of
the time period set forth in this Section 4(d).

                  (e) PAYMENT UPON TERMINATION OF EMPLOYMENT OF MANAGEMENT
STOCKHOLDER OTHER THAN RIFKIN OR KIMMEL. If the employment of a Management
Stockholder other than Rifkin or Kimmel with DHS is terminated, then the
Management Stockholders whose employment with DHS has not been terminated shall
have the option, for a period of sixty (60) days from the date of such
termination, to purchase (in such proportions as they shall agree upon or, if
they cannot agree, in proportion to their ownership of DHS Class A Common Stock
other than the stock of the terminated Management Stockholder) and, if such
option is accepted, such terminated Management Stockholder shall sell all of the
shares of Stock held by such terminated Management Stockholder (the "TERMINATED
MANAGER'S STOCK") on terms substantially identical to those set forth in Section
7 hereof (other than subsections (c) and (d) thereof) and for a price determined
in accordance with Subsections (i) and (ii) of this Section 4(e). If all of the
Terminated Manager's Stock is not purchased by the other Management
Stockholders, DHS shall purchase, within ninety (90) days after the date of said
termination, and such terminated Management Stockholder shall sell, all of the
Terminated Manager's Stock upon the following terms and at the following prices:

                           (i) if such Management Stockholder's employment is
         terminated (A) by DHS for any of the specific reasons enumerated in
         Section 4.3(a) of such Management Stockholder's DHS Employment
         Agreement, or, if no such agreement is then in effect, for "good cause"

                                       -6-
<PAGE>

         under applicable law, or (B) by the Management Stockholder for any
         reason not constituting "constructive termination" as defined in
         Section 4.4(b) of such Management Stockholder's DHS Employment
         Agreement, then at a price equal to the lower of such Management
         Stockholder's acquisition cost for his Stock or One Dollar ($1.00) per
         share, and upon the terms set forth in Section 7 hereof; or

                           (ii) if such Management Stockholder's employment is
         terminated (A) by death, or by "disability" (as defined herein), or (B)
         by expiration of the term of such DHS Employment Agreement, or (C) by
         DHS without good cause as contemplated by Section 4.3(b) of such
         Employment Agreement, or (D) by the Management Stockholder for reasons
         constituting "constructive termination" under such Agreement, then at
         the price set forth in Section 6 hereof, and upon the terms set forth
         in Section 7 hereof.

If DHS is required, pursuant to the provisions of this Section 4(e), to purchase
the Terminated Manager's Stock at a price determined pursuant to Subsection (ii)
hereof, DHS shall, as a condition precedent to the closing of such purchase, on
or before the Closing Date for its acquisition of the Terminated Manager's
Stock, pay to (A) the Series A Investor all of the dividends then accrued but
unpaid on the Series A Preferred Stock plus all accrued and unpaid interest
thereon (whether by payment of cash or set off of any accrued but unpaid
interest under the Promissory Note issued by the Series A Investor to DHS), or
otherwise make provision for the payment of such dividends that is acceptable to
the Series A Investor, in its reasonable discretion, (B) the Series B Investor
all of the dividends then accrued but unpaid on the Series B Preferred Stock
plus all accrued and unpaid interest thereon or otherwise make provision for the
payment of such dividends that is acceptable to the Series B Investor, in its
reasonable discretion, and (C) the Series C Investor all of the dividends then
accrued but unpaid on the Series C Preferred Stock plus all accrued and unpaid
interest thereon or otherwise make provision for the payment of such dividends
that is acceptable to the Series C Investor, in its reasonable discretion.
Notwithstanding the foregoing, in the event DHS has paid the Series C Investor
as set forth in this paragraph prior to the consummation of a Qualified Public
Offering on or before August 30, 1998 as defined in the Articles of Amendment
and Restatement dated September 4, 1996, then on or before the consummation of a
Qualified Public Offering on or before August 30, 1998 (at a price per share not
less than the weighted average price paid or to be paid by the Series C Investor
for all shares of Series C Preferred Stock then oustanding) the Series C
Investor shall pay DHS an amount equal to the amount of dividends and interest
paid to the Series C Investor pursuant to this Section.

                  (f) TERMINATION OF EMPLOYMENT, DEATH, DISABILITY OF RIFKIN AND
KIMMEL.

                                       -7-
<PAGE>

                           (i) TERMINATION OF EMPLOYMENT WITHOUT GOOD CAUSE.
         Except as set forth in the proviso to this sentence, if the employment
         of Rifkin or Kimmel, as the case may be, with DHS is terminated (A) by
         DHS for any of the specific reasons enumerated in Section 4.3(a) of his
         respective DHS Employment Agreement (or, if no such agreement is then
         in effect, for "good cause" under applicable law), or (B) by Rifkin or
         Kimmel, as the case may be, for any reason not constituting
         "constructive termination" as defined in Section 4.4(b) of such DHS
         Employment Agreement, then Rifkin or Kimmel, as the case may be, shall
         sell, and DHS shall purchase, all of the stock then registered in
         Rifkin's or Kimmel's name, as the case may be, at a price equal to the
         lower of Rifkin's or Kimmel's, as the case may be, acquisition cost for
         his Stock or One Dollar ($1.00) per share, and upon the terms provided
         in Section 7 hereof; provided, however, that the provisions of this
         paragraph 4(f)(i) shall not apply to any shares of capital stock of DHS
         held by Rifkin or Kimmel on the date hereof (or received as a
         distribution on or in respect of such shares after the date hereof as
         the result of any recapitalization, stock split or similar event).

                           (ii) DEATH; DISABILITY. Upon each of (A) the death of
         Rifkin or Kimmel, as the case may be, and the appointment and
         qualification of such deceased stockholder's personal representative,
         and (B) the "Disability" of Rifkin or Kimmel (as such term is defined
         in each such shareholder's current employment agreement with DHS or, if
         there is none, as reasonably determined by the Board of Directors of
         DHS), as the case may be, such personal representative, Rifkin or
         Kimmel, as the case may be, may, for a period of sixty (60) days from
         the date of such appointment and qualification or disability, as the
         case may be, offer to the other Management Stockholders the option to
         purchase (in such proportions as they shall agree upon or, if they
         cannot agree, in proportion to their ownership of the DHS Class A
         Common Stock), all of the shares of Stock held by such personal
         representative, Rifkin or Kimmel, as the case may be, on terms
         substantially identical to those set forth in Section 7 hereof (other
         than Subsections (c) and (d) thereof) and at a price determined in
         accordance with the terms of Section 6 hereof. If the option to
         purchase all of the shares of Stock so offered is not exercised or
         accepted within such sixty (60) day period, then such personal
         representative, Rifkin or Kimmel, as the case may be, shall be entitled
         to sell, by providing written notice to DHS, and DHS shall be required
         to purchase upon receipt of such notice, all or any portion of such
         shares of Stock held by Rifkin or Kimmel, as the case may be, as such
         number of shares is set forth in such written notice, at the price and
         upon the terms provided in Sections 6 and 7 hereof.

                           (iii) TERMINATION OF EMPLOYMENT UNDER OTHER
         CIRCUMSTANCES. If Rifkin's or Kimmel's employment is terminated (A)

                                       -8-
<PAGE>

         by expiration of the term of his respective DHS Employment Agreement,
         or (B) by DHS without good cause as contemplated by Section 4.3(b) of
         such Employment Agreements, or (C) by Rifkin or Kimmel, as the case may
         be, for reasons constituting "constructive termination" under such
         Agreements, then DHS shall purchase, within ninety (90) days after the
         date of such termination, and Rifkin and Kimmel shall sell, as the case
         may be, those shares (and only those shares) of capital stock of DHS
         acquired by Rifkin or Kimmel, as the case may be, after the date hereof
         (other than as a distribution on or in respect of shares held on the
         date hereof through a recapitalization, stock split, or similar event)
         at the price set forth in Section 6 hereof, and upon the terms set
         forth in Section 7 hereof.

If DHS is required, pursuant to the provisions of this Section 4(f), to purchase
the Terminated Manager's Stock at a price determined pursuant to Subsection (ii)
hereof, DHS shall, as a condition precedent to the closing of such purchase, on
or before the Closing Date for its acquisition of the Terminated Manager's
Stock, pay to (A) the Series A Investor all of the dividends then accrued but
unpaid on the Series A Preferred Stock plus all accrued and unpaid interest
thereon (whether by payment of cash or set off of any accrued but unpaid
interest under the Promissory Note issued by the Series A Investor to DHS), or
otherwise make provision for the payment of such dividends that is acceptable to
the Series A Investor, in its reasonable discretion, (B) the Series B Investor
all of the dividends then accrued but unpaid on the Series B Preferred Stock
plus all accrued and unpaid interest thereon or otherwise make provision for the
payment of such dividends that is acceptable to the Series B Investor, in its
reasonable discretion, and (C) the Series C Investor all of the dividends then
accrued but unpaid on the Series C Preferred Stock plus all accrued and unpaid
interest thereon or otherwise make provision for the payment of such dividends
that is acceptable to the Series C Investor, in its reasonable discretion.
Notwithstanding the foregoing, in the event DHS has paid the Series C Investor
as set forth in this paragraph prior to the consummation of a Qualified Public
Offering on or before August 30, 1998 as defined in the Articles of Amendment
and Restatement dated September 4, 1996, then on or before the consummation of a
Qualified Public Offering on or before August 30, 1998 (at a price per share not
less than the weighted average price paid or to be paid by the Series C Investor
for all shares of Series C Preferred Stock then oustanding) the Series C
Investor shall pay DHS an amount equal to the amount of dividends and interest
paid to the Series C Investor pursuant to this Section.

                  (g) PRICE ADJUSTMENTS FOLLOWING A CHANGE IN CONTROL OF DHS. If
the employment of a Management Stockholder other than Rifkin or Kimmel with DHS
is terminated pursuant to the provisions in Section 4(e)(ii)(C) or (D) above,
and there occurs a Change in Control of DHS within the first twenty-four months
following the date of such termination, DHS agrees to pay or cause to be paid to
such terminated Management Stockholder (or to his heirs,

                                       9

<PAGE>

legatees and/or guardians), in addition to the purchase price for such
terminated Management Stockholder's Stock as determined pursuant to Section 7
hereof, the value of such terminated Management Stockholder's fair, allocative,
share of any consideration that would have been payable to such terminated
Management Stockholder (less any such consideration actually received by such
Management Stockholder as a result of a sale of his Stock, whether to another
Management Stockholder, DHS or another person) or to DHS upon, and as a result
of, such a Change in Control of DHS within such twenty-four month period. Such
payment shall be made by DHS when and as DHS or the other DHS Stockholders
receive consideration as a result of such a Change in Control, and shall be paid
by DHS based upon such terminated Management Stockholder's pro-rata equity
interest in DHS at the time of termination. Any payment by DHS pursuant to this
Section 4(f) may, at DHS' option, be made by delivery of (i) cash, (ii) a
promissory note with a term of not more than ten years and interest at a rate
calculated pursuant to Section 1274(d) of the Internal Revenue Code of 1986, or
(iii) an appropriate in-kind distribution of any consideration received as a
result of such Change in Control. The parties hereto acknowledge and agree that
each Partner of the LP who has entered into a Professional Service Employment
Agreement with the LLC shall be entitled to receive, and pursuant to Section
7.3.3(i) of the Limited Partnership Agreement has received, the benefit of the
substantive provisions set forth in this Section 4(g), upon the sale of his
Limited Partner Interest in the LP due to the termination of his employment with
BMG resulting from a termination by the LLC without good cause or a
"constructive termination," as defined therein.

                  5.       VOLUNTARY TRANSFERS OF STOCK.

                  (a) STOCK RESTRICTED. Subject to the rights of the holders of
Convertible Preferred Stock set forth in the DHS Amended and Restated Articles,
each Stockholder agrees that, during his lifetime or its corporate existence or
otherwise, he or it will not sell, transfer, exchange, assign or otherwise
dispose of (by sale, gift, or otherwise), or mortgage, hypothecate, lien,
pledge, encumber or otherwise cause a security interest to be created in any of
his or its Stock, except upon satisfaction of the conditions set forth in this
Section 5 and Section 4 above. Notwithstanding the foregoing, (i) each
Management Stockholder shall be entitled to transfer all or any portion of his
shares of Stock to a trust solely for the benefit of himself, his spouse and/or
his lineal descendants provided that, as a condition of said transfer, (A) the
agreement governing said trust requires transfers of any beneficial interests
therein (other than among such permitted persons) to be treated as transfers of
Stock hereunder and subject to the terms hereof, and (B) all trustees of said
trust execute and deliver to the parties hereto a counterpart of this Agreement
and otherwise agree to be bound by all of the terms and provisions hereof with
respect to the Stock, and (ii) each holder of Convertible Preferred Stock and of
Class B Common Stock may transfer its Convertible Preferred Stock or Class B
Common Stock, as the case may be, to any entity all of the ownership interests
in which are owned by such holder, provided that such transferee executes and
delivers to the parties hereto a counterpart of this Agreement and otherwise
agrees to be bound by all of the terms and provisions hereof.

                  (b) DELEGATION RIGHTS. If DHS is unable to exercise any of its
purchase rights hereunder, it shall be entitled to delegate such rights to such
of the Stockholders who desire to purchase stock upon the occurrence of the
events set forth in Sections 4(a)(i) or (ii) hereof, provided such stockholders,
as a condition of such obligation, shall be entitled to purchase such stock pro
rata as consolidated pursuant to Section 4(a)(ii) hereof.

                  (c) VOLUNTARY TRANSFERS BY MANAGEMENT STOCKHOLDERS.

                           (i) OPTION OF OTHER MANAGEMENT STOCKHOLDERS. A
         Management Stockholder shall have the right to receive a bona fide
         offer to purchase (which he is willing to accept) (a "MANAGEMENT
         OFFER") from any independent third person capable of consummating such
         a sale of all, but not less than all, of his Stock (the "MANAGEMENT
         OFFERED STOCK"). Before accepting a Management Offer, such Management
         Stockholder shall first offer in writing (the "MANAGEMENT STOCKHOLDER'S
         Offer") to sell the Management Offered Stock to the other Management
         Stockholders (the "OTHER MANAGEMENT STOCKHOLDERS") at the price and on
         the terms on which such selling Management Stockholder proposes to
         transfer the Management Offered Stock to the proposed third party
         transferee. The Management Stockholder's Offer shall set forth (A) the

                                       11
  
<PAGE>

         number of shares of the Management Offered Stock, (B) the name and
         address of the proposed transferee, (C) the amount of consideration to
         be received by the selling Stockholder, and (D) the method of proposed
         payment. A copy of the Management Stockholder's Offer shall
         simultaneously also be sent to all of the other Stockholders and to
         DHS.

                           The Other Management Stockholders shall have the
         option to acquire all or any of the shares of Management Offered Stock
         at the price and upon the terms provided in the Management
         Stockholder's Offer. If more than one Other Management Stockholder
         desires to purchase the Management Offered Stock, such Management
         Offered Stock shall be purchased by them in such proportions as they
         may agree. In the absence of agreement, each of the Other Management
         Stockholders desiring to purchase the Management Offered Stock shall be
         entitled to purchase up to that number of shares of Management Offered
         Stock which is equal to the product of such number of shares of
         Management Offered Stock divided by the number of other Management
         Stockholders desiring to purchase such shares of Stock. The Other
         Management Stockholders shall have the right to exercise their
         respective options to purchase the Management Offered Stock, for a
         period of thirty (30) days following their receipt of the Management
         Stockholder's Offer, by notifying the selling Management Stockholder in
         writing of their respective intentions to purchase at Closing (as
         defined in Section 7(e) hereof) all or any shares of the Management
         Offered Stock.

                           (ii) OPTION OF THE HOLDERS OF CLASS B COMMON STOCK.
         If the Other Management Stockholders do not accept the Management
         Stockholder's Offer to purchase all of the shares of Management Offered
         Stock within the period of thirty (30) days provided in Section
         5(c)(i), then the selling Management Stockholder, immediately
         thereafter, shall be deemed to have made an offer (the "MANAGEMENT
         STOCKHOLDER'S SECOND OFFER") to sell all of the remaining shares of the
         Management Offered Stock (the "REMAINING MANAGEMENT OFFERED STOCK") to
         the holders of Class B Common Stock at the price and upon the terms
         provided in the Management Stockholder's Offer. The holders of the
         Class B Common Stock shall have the option, for a period of fifteen
         (15) days after the earlier to occur of (A) expiration of the thirty
         (30) day period provided in Section 5(c)(i), or (B) notification by all
         of the Other Management Stockholders to the holders of Class B Common
         Stock to the effect that the Other Management Stockholders, in the
         aggregate, have elected to purchase less than all of the shares of
         Management Offered Stock as provided in Section 5(c)(i), to purchase
         all of the Remaining Management Offered Stock, upon written
         notification to the selling Management Stockholder, at the price and
         upon the terms provided in this Section 5(c). If more than one holder
         of Class B Common Stock desires to purchase the Remaining Management
         Offered Stock, such

                                       12

<PAGE>

         Remaining Management Offered Stock shall be purchased by them in such
         proportions as they may agree. In the absence of agreement, each of the
         holders of Class B Common Stock desiring to purchase the Remaining
         Management Offered Stock shall be entitled to purchase up to that
         number of shares of Remaining Management Offered Stock which is equal
         to the product of his percentage interest of all of the shares of Class
         B Common Stock held by all such holders of Class B Common Stock times
         the number of shares of Remaining Management Offered Stock available
         for purchase hereunder. The holders of Class B Common Stock shall have
         the right to exercise their respective options to purchase the
         Remaining Management Offered Stock by notifying the selling Management
         Stockholder in writing of their respective intentions to purchase at
         Closing (as defined in Section 7(e) hereof) all or any shares of the
         Remaining Management Offered Stock.

                           (iii) OPTION OF THE HOLDERS OF CONVERTIBLE PREFERRED
         STOCK. If the holders of Class B Common Stock do not accept the
         Management Stockholder's Second Offer to purchase all of the shares of
         Remaining Management Offered Stock within the period of fifteen (15)
         days provided in Section 5(c)(ii), then the selling Management
         Stockholder, immediately thereafter, shall be deemed to have made an
         offer (the "MANAGEMENT STOCKHOLDER'S THIRD OFFER") to sell all of the
         remaining shares of the Remaining Management Offered Stock (the
         "AVAILABLE MANAGEMENT OFFERED STOCK") to the holders of Convertible
         Preferred Stock at the price and upon the terms provided in the
         Management Stockholder's Offer. The holders of Convertible Preferred
         Stock shall have the option, for a period of fifteen (15) days after
         the earlier to occur of (A) expiration of the fifteen (15) day period
         provided in Section 5(c)(ii), or (B) notification by all of the holders
         of Class B Common Stock to the holders of Convertible Preferred Stock
         to the effect that the holders of Class B Common Stock have elected to
         purchase less than all of the shares of Remaining Management Offered
         Stock as provided in Section 5(c)(ii), to purchase all of the Available
         Management Offered Stock, upon written notification to the selling
         Management Stockholder, at the price and upon the terms provided in
         this Section 5(c). If more than one holder of Convertible Preferred
         Stock desires to purchase the Available Management Offered Stock, such
         Available Management Offered Stock shall be purchased by them in such
         proportions as they may agree. In the absence of agreement, each of the
         holders of Convertible Preferred Stock desiring to purchase the
         Available Management Offered Stock shall be entitled to purchase up to
         that number of shares of Available Management Offered Stock which is
         equal to the product of his percentage interest of all of the shares of
         Convertible Preferred Stock held by all such holders of Convertible
         Preferred Stock times the number of shares of Available Management
         Offered Stock available for purchase hereunder. The holders of
         Convertible Preferred Stock shall have the

                                       13

<PAGE>

         right to exercise their respective options to purchase the Available
         Management Offered Stock by notifying the selling Management
         Stockholder in writing of their respective intentions to purchase at
         Closing (as defined in Section 7(e) hereof) all or any shares of the
         Available Management Offered Stock.

                           (iv) OPTION OF DHS. If the holders of Convertible
         Preferred Stock do not accept the Management Stockholder's Third Offer
         to purchase all of the shares of Available Management Offered Stock
         within the period of fifteen (15) days provided above in Section
         5(c)(iii), then the selling Management Stockholder, immediately
         thereafter, shall be deemed to have made an offer (the "FINAL
         MANAGEMENT STOCKHOLDER'S OFFER") to sell all of the remaining shares of
         the Available Management Offered Stock (the "FINAL MANAGEMENT OFFERED
         STOCK") to DHS at the price and upon the terms provided in the
         Management Stockholder's Offer. DHS shall have the option, for a period
         of fifteen (15) days after the earlier to occur of (i) expiration of
         the fifteen (15) day period provided in Section 5(c)(iii), or (ii)
         notification by all of the holders of Convertible Preferred Stock to
         DHS to the effect that the holders of Convertible Preferred Stock have
         elected to purchase less than all of the shares of Available Management
         Offered Stock as provided in Section 5(c)(iii), to purchase all or some
         of the Final Management Offered Stock, upon written notification to the
         selling Management Stockholder, at the price and upon the terms
         provided in the Management Stockholder's Offer.

                           (v) TRANSFERS TO THIRD PARTIES. If (A) a Management
         Stockholder elects to transfer all of his shares of Management Stock;
         (B) said Management Stockholder strictly complies with the provisions
         of Sections 5(c)(i) through 5(c)(iv) above; (C) the Remaining
         Management Stockholders, the holders of Class B Common Stock, the
         holders of Convertible Preferred Stock and DHS elect to purchase, in
         the aggregate, less than all of the shares of Management Offered Stock;
         and (D) the Management Stockholder who desires to transfer the
         Management Offered Stock complies with the terms of this Section
         5(c)(v), then all of the Management Offered Stock remaining unsold
         pursuant to the rights of refusal contained in this Section 5(c) may be
         sold by the selling Management Stockholder to the third party named in
         the Management Stockholder's Offer within a period of thirty (30) days
         after the expiration of the fifteen (15) day period provided in Section
         5(c)(iv). Such remaining Management Offered Stock may be transferred to
         the third party named in the Management Stockholder's Offer; provided
         that (X) such shares are sold at the price and on the terms set forth
         in the Management Stockholder's Offer; (Y) the shares so transferred
         shall remain subject to all of the provisions of this Agreement; and
         (Z) the third party transferee shall execute an instrument acceptable

         which such third party becomes a party to this Agreement and agrees to
         be bound by all of the provisions and terms or conditions hereof.

               (d) VOLUNTARY TRANSFERS BY THE HOLDERS OF CLASS B COMMON STOCK.


                           (i) OPTION OF OTHER STOCKHOLDERS. Each holder of
         Class B Common Stock shall have the right to receive a bona fide offer
         to purchase (which it is willing to accept) (a "CLASS B COMMON OFFER")
         from any independent third person capable of consummating such a sale
         of all, but not less than all, of its Class B Common Stock (the "CLASS
         B COMMON OFFERED STOCK"). Before accepting a Class B Common Offer, the
         holder of Class B Common Stock shall first offer in writing (the "CLASS
         B COMMON STOCKHOLDER'S OFFER") to sell the Class B Common Offered Stock
         to the other Stockholders (the "OTHER STOCKHOLDERS") at the price and

         acquire all or any of the shares of Class B Common Offered Stock at the
         price and upon the terms provided in the Class B Common Stockholder's

         B Common Offered Stock, such Class B Common Offered Stock shall be
         purchased by them in such proportions as they may agree. In the absence
         of agreement, each of the Other Stockholders desiring to purchase the

         number of shares of Class B Common Offered Stock which is equal to the
         product of his percentage interest of all of the shares of DHS Capital
         Stock then held by all such Other Stockholders times the number of
         shares of Class B Common Offered Stock available for purchase
         hereunder. The Other Stockholders shall have the right to exercise
         their respective options to purchase the Class B Common Offered Stock,

                           (ii) OPTION OF DHS. If the Other Stockholders do not
         accept the Class B Common Stockholder's Offer to purchase all of the

                                       15

<PAGE>

         shares of Class B Common Offered Stock within the period of thirty (30)
         days provided above in Section 5(d)(i), then the holders of Class B
         Common Stock, immediately thereafter, shall be deemed to have made an
         offer (the "FINAL CLASS B COMMON STOCK OFFER") to sell all of the
         remaining shares of the Class B Common Offered Stock (the "REMAINING
         CLASS B COMMON OFFERED STOCK") to DHS at the price and upon the terms
         provided in the Class B Common Stockholder's Offer. DHS shall have the
         option, for a period of fifteen (15) days after the earlier to occur of
         (i) expiration of the thirty (30) day period provided in Section
         5(d)(i), or (ii) notification by all of the Other Stockholders to DHS
         to the effect that the Other Stockholders have elected to purchase less
         than all of the shares of Class B Common Offered Stock as provided in
         Section 5(d)(i), to purchase all of the Remaining Class B Common
         Offered Stock, upon written notification to such holder of Class B
         Common Stock, at the price and upon the terms provided in the Class B
         Common Stockholder's Offer.

                           (iii) TRANSFERS TO THIRD PARTIES. If (A) the holder
         of Class B Common Stock elects to transfer all of its shares of Class B
         Common Stock; (B) the holder of Class B Common Stock strictly complies
         with the provisions of Sections 5(d)(ii) and (iii); (C) the Other

         of the shares of Class B Common Offered Stock; and (D) the holder of
         Class B Common Stock complies with the terms of this Section 5(c)(iii),
         then all of the Class B Common Offered Stock may be sold by the holder
         of Class B Common Stock to the third party named in the Class B Common
         Stockholder's Offer within a period of fifteen (15) days after the
         expiration of the fifteen (15) day period provided in Section 5(d)(ii).
         Such Class B Common Offered Stock may be transferred to the third party
         named in the Class B Common Stockholder's Offer; provided that (X) such
         shares are sold at the price and on the terms set forth in the Class B
         Common Stockholder's Offer; (Y) the shares so transferred shall remain
         subject to all of the provisions of this Agreement; and (Z) the third
         party transferee shall execute an instrument acceptable to counsel for
         DHS, pursuant to which such third party becomes a party to this
         Agreement and agrees to be bound by all of the provisions and terms or
         conditions hereof.

                  (e) VOLUNTARY TRANSFERS BY THE HOLDERS OF CONVERTIBLE
PREFERRED STOCK. Notwithstanding any other provision of this Agreement or any
other agreement to which DHS and either of the Series A Investor, the Series B
Investor or the Series C Investor are parties, no shares of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock, as the case may be,
may be voluntarily transferred pursuant to this Section 5(e) or otherwise if, at
the time of such attempt to transfer, (1) the Series A Investor, the Series B
Investor or the Series C Investor, respectively, has not made full payment to
DHS in cash for all shares of Series A Preferred Stock, Series B Preferred Stock
or Series C Preferred Stock, as the case may be, held by the Series A Investor,

                                       16

<PAGE>

the Series B Investor or the Series C Investor, respectively, including all
amounts of principal and interest under any note given in partial consideration
for such shares, or (2) any holder of Convertible Preferred Stock proposing to
sell such stock pursuant to this Section 5(e) holds, at the time of such attempt
at transfer, rights to purchase additional shares of Convertible Preferred
Stock.

                           (i) OPTION OF DHS. Except as otherwise herein
         provided, each holder of Convertible Preferred Stock shall have the
         right to receive a bona fide offer to purchase (which it is willing to
         accept) (a "CONVERTIBLE PREFERRED STOCK OFFER"), from any independent
         third person capable of consummating such a sale, any or all of its
         shares of Convertible Preferred Stock (the "PREFERRED OFFERED STOCK").
         Before accepting a Convertible Preferred Stock Offer, the holder of
         Convertible Preferred Stock shall first offer in writing (the
         "CONVERTIBLE PREFERRED STOCKHOLDER'S Offer") to sell the Preferred
         Offered Stock to DHS at the price and on the terms on which the holder
         of Convertible Preferred Stock proposes to transfer the Preferred
         Offered Stock to the proposed third party transferee. The Convertible
         Preferred Stockholder's Offer shall set forth (A) the number of shares
         of the Preferred Offered Stock, (B) the name and address of the
         proposed transferee, (C) the amount of consideration to be received by
         the holder of Convertible Preferred Stock, and (D) the method of
         proposed payment.

                           DHS shall have the option to acquire all, but not
         less than all, of the shares of Preferred Offered Stock at the price
         and upon the terms provided in the Convertible Preferred Stockholder's
         Offer. DHS shall have the right to exercise its option to purchase the
         Preferred Offered Stock, for a period of thirty (30) days following its
         receipt of the Convertible Preferred Stockholder's Offer, by notifying
         all of the holders of Convertible Preferred Stock in writing of its
         intention to purchase at Closing (as defined in Section 7(e) hereof)
         all or any shares of the Preferred Offered Stock.

                           (ii) OPTION OF THE HOLDERS OF CONVERTIBLE PREFERRED
         STOCK. If DHS does not accept the Convertible Preferred Stockholder's
         Offer to purchase all of the Shares of Preferred Offered Stock within
         the period of thirty (30) days provided in Section 5(e)(i), then the
         selling holder of Convertible Preferred Stock, immediately thereafter,
         shall be deemed to have made an offer (the "SECOND CONVERTIBLE
         PREFERRED STOCKHOLDER'S OFFER") to sell all of the remaining shares of
         the Preferred Offered Stock (the "REMAINING PREFERRED OFFERED STOCK")
         to the other holders of Convertible Preferred Stock at the price and
         upon the terms provided in the Convertible Preferred Stockholder's
         Offer. The other holders of Convertible Preferred Stock shall have the
         option, for a period of fifteen (15) days after the earlier to occur of
         (A) expiration of the thirty (30) day period provided in Section
         5(e)(ii), or (B) notification by DHS to

                                       17

<PAGE>

         the holders of Convertible Preferred Stock to the effect that DHS has
         elected to purchase less than all of the shares of Remaining Preferred
         Offered Stock as provided in Section 5(e)(ii), to purchase all of the
         Remaining Preferred Offered Stock upon written notification to the
         selling holder of Remaining Preferred Offered Stock, at the price and
         upon the terms provided in the Convertible Preferred Stockholder's
         Offer. If more than one holder of Convertible Preferred Stock desires
         to purchase the Remaining Preferred Offered Stock, such Remaining
         Preferred Offered Stock shall be purchased by them in such proportions
         as they may agree. In the absence of agreement, each of the holders of
         Convertible Preferred Stock desiring to purchase the Remaining
         Preferred Offered Stock shall be entitled to purchase up to that number
         of shares of Remaining Preferred Offered Stock which is equal to the
         product of his percentage interest of all of the shares of Convertible
         Preferred Stock held by all such holders of Convertible Preferred Stock
         times the number of shares of Remaining Preferred Offered Stock
         available for purchase hereunder. The holders of Convertible Preferred
         Stock shall have the right to exercise their respective options to
         purchase the Remaining Preferred Offered Stock by notifying the selling
         holder of Convertible Preferred Stock in writing of their respective
         intentions to purchase at Closing (as defined in Section 7(e) hereof)
         all or any shares of the Remaining Preferred Offered Stock.

                           (iii) TRANSFERS TO THIRD PARTIES. If (A) the holder
         of Convertible Preferred Stock elects to transfer all of its shares of
         Convertible Preferred Stock; (B) the holder of Convertible Preferred
         Stock strictly complies with the provisions of Sections 5(e)(i) and
         (ii); (C) DHS does not exercise its right to purchase all, but not less
         than all, of the shares of Preferred Offered Stock and the holders of
         Convertible Preferred Stock elect to purchase, in the aggregate, less
         than all of the shares of the Remaining Preferred Offered Stock; and
         (D) the holder of Convertible Preferred Stock complies with the terms
         of this Section 5(e)(iii), then all, but not less than all, of the
         shares of the Remaining Preferred Offered Stock may be sold by the
         holder of Convertible Preferred Stock to the third party named in the
         Convertible Preferred Stockholder's Offer within a period of thirty
         (30) days after the expiration of the fifteen (15) day period provided
         in Section 5(e)(ii). Such Remaining Preferred Offered Stock may be
         transferred to the third party named in the Convertible Preferred
         Stockholder's Offer; provided that (X) such shares are sold at the
         price and on the terms set forth in the Convertible Preferred
         Stockholder's Offer; (Y) the shares so transferred shall remain subject
         to all of the provisions of this Agreement; and (Z) the third party
         transferee shall execute an instrument reasonably acceptable to counsel
         for DHS, pursuant to which such third party becomes a party to this
         Agreement and agrees to be bound by all of the provisions and terms or
         conditions hereof.

                  (f) The closing for any purchase by a Stockholder or DHS of
shares proposed to be voluntarily transferred by a Stockholder pursuant to a
bona fide third party offer under this Section 5 shall be held at 10:00 a.m. at
the principal offices of DHS in Owings Mills, Maryland, on the date set forth
for the closing in the bona fide offer. In the event that no such date is set
forth in the bona fide offer, the closing shall be held at the principal offices
of DHS in Owings Mills, Maryland, at 10:00 a.m., not later than the 30th day
after the last to expire of the time periods for giving of notice provided for

                  6. PURCHASE PRICE OF STOCK FOR PURPOSES OF INVOLUNTARY
TRANSFERS AND SECTIONS 4(E)(II) AND 4(F)(II).


                  (a) AGREEMENT OF THE PARTIES. With respect to purchases
governed by the provisions of Section 4(d), Section 4(e)(ii) and Section
4(f)(ii) hereof, if the purchaser of Stock hereunder, on the one hand, and the
transferring Stockholder, on the other hand, agree in writing as to the purchase
price for the Stock to be sold pursuant to Section 4(d), 4(e)(ii) or Section
4(f)(ii) hereof, as the case may be, such agreed price shall be the purchase
price for such Stock. If no agreement on the purchase price of such Stock can be
reached within thirty (30) days from the date of the occurrence of the
applicable event under the provisions of Section 4(d), or 4(e)(ii) or, with
respect to the occurrence of an event governed by Section 4(f)(ii), within
thirty (30) days after the receipt of the notice required to be determined
thereunder, as the case may be (provided that, with respect to the death of a
Management Stockholder other than Rifkin or Kimmel, such thirty (30) day period
shall commence upon the appointment and qualification of such deceased
Management Stockholder's personal representative), then the purchase price of
said Stock shall be determined pursuant to Section 6(b) hereof.

                  (b) APPRAISAL.

                           (i) If the purchase price of Stock to be sold
         pursuant to Section 4(d), 4(e)(ii) or 4(f)(ii) is not agreed upon as
         provided in Section 6(a) within the time period stated therein, then
         within fourteen (14) days thereafter an appraiser or appraisers shall
         be jointly selected by the transferring Stockholder, on the one hand,
         and DHS on the other hand, and such jointly selected appraiser or
         appraisers shall determine the "fair market value of the Stock," which
         determination shall be binding and conclusive upon all parties. For
         purposes of this Section 6(b), the "FAIR MARKET VALUE OF THE STOCK"
         shall be an amount equal to the "Fair Market Value Per Share" of the
         Class being sold and purchased hereunder, multiplied by the number of
         shares of Stock of said Class of the transferring Stockholder which are
         being sold and purchased hereunder. "FAIR MARKET VALUE PER SHARE" shall
         be an amount as of the Disposition Date as determined by appraisal
         using such methods as

                                       19

<PAGE>

         the appraisers appointed hereunder determine, in the exercise of their
         sole discretion, is appropriate pursuant to this Section 6(b), taking
         into account any liquidation preferences or other rights attendant to
         such class, any minority stockholder discount, majority stockholder
         premium or marketability or other discount or premium, as the case may
         be. "DISPOSITION DATE" shall be the last day of the calendar month
         immediately preceding the event giving rise to the purchase of the
         Stock under Section 4 hereof.

                           (ii) If the transferring Stockholder, on the one
         hand, and DHS on the other hand, do not agree upon the selection of an
         appraiser or appraisers, as provided in Section 6(b)(i), within the
         period therein stated, then, within seven (7) days after the expiration
         of the fourteen (14) day period provided for in Section 6(b)(i) hereof,
         the transferring Stockholder shall appoint an appraiser, and DHS shall
         appoint a second appraiser. The two (2) appraisers so appointed shall
         appoint a third appraiser within seven (7) days after both shall have
         been appointed. If either the transferring Stockholder or DHS shall
         fail to so appoint an appraiser, the appraiser duly appointed by the
         other shall serve as the sole appraiser and such appraiser shall
         determine the fair market value of the Stock and such determination
         shall be binding, final and conclusive on all parties. The said
         appraisers so appointed (or the sole appraiser if any party fails to
         select an appraiser as provided above), shall, within thirty (30) days
         after the last appointment thereof determine the fair market value of
         the Stock and the determination of such appraiser shall be
         determinative of the fair market value of the Stock for the purposes of
         this Agreement and shall be binding, final and conclusive on all
         parties. If the appraisers cannot agree on the fair market value of the
         Stock, within the time allotted, then such fair market value shall be
         the median of the two appraisals closest in value to each other.

                           (iii) All expenses incurred in the appraisal process
         shall be borne and paid equally by the transferring Stockholder, and
         DHS.

                  7. PAYMENT OF PURCHASE PRICE. The payment of any purchase
price for Stock transferred  pursuant to Section 4 hereof may be made on such
terms as are agreed upon by the parties but,  absent such agreement shall be
made as follows:

                  (a) CASH PORTION.(a) CASH PORTION. Subject to the terms of
Section 7(d) hereof and, with respect to any Involuntary Transfer, subject to
such other terms and conditions as may be required by any court which has then
exercised jurisdiction over any Involuntary Transfer Stockholder with respect to
its Stock, or to any assignee, trustee in bankruptcy or successor in interest,
as the case may be, (i) in the event of any transfer pursuant to Section 4
(other than as a result of the death of a Management Stockholder), (A) where DHS
is the purchaser, ten

                                       20

<PAGE>

percent (10%) of the total purchase price of the Stock shall be paid in cash by
DHS on the Closing Date, as defined in Section 7(e) hereof, and (B) where any
party other than DHS is the purchaser, the entire amount of the purchase price
of the Stock shall be paid by check by such purchaser(s) on the Closing Date,
and (ii) in the event of any transfer as a result of the death of a Management
Stockholder, DHS shall pay by check on the Closing Date the greater of (A) the
proceeds of any life insurance policy or policies (but not in excess of the
purchase price to be paid by DHS hereunder) owned by DHS on which the deceased
Management Stockholder is the named insured and DHS is the applicant, owner and
beneficiary, and which policy or policies were purchased for the purpose of
using the proceeds thereof to purchase the shares of Stock of the deceased
Management Stockholder upon his death (rather than to reimburse DHS for the loss
of the services to be provided to DHS by the deceased Management Stockholder),
or (B) ten percent (10%) of the total purchase price of the Stock held by such
deceased Management Stockholder. Notwithstanding the foregoing, if DHS is a
purchaser hereunder but is unable, under applicable law, to make all or any
portion of any payment otherwise due hereunder on the Closing Date, DHS shall
pay such portion, if any, as applicable law permits, and the balance of such
payment shall be payable pursuant to the provisions of Section 7(b) hereof.

                  (b) PROMISSORY NOTE. The balance of the purchase price shall
be represented by a promissory note of DHS, payable in seven (7) equal annual
installments of principal and interest, the first of which shall be due and
payable on the first anniversary of delivery of such note. The note shall be
substantially in the form of the promissory note attached hereto and made a part
hereof as EXHIBIT A, and contain terms and conditions substantially similar to
the terms and conditions contained therein. Interest shall accrue on, and be
payable with, the unpaid balance of said note from the Closing Date at a rate
equal to the applicable federal rate for long-term debt instruments then
existing on the date of issuance under Code Section 1274(d)(1). As security for
payment of the amounts due under such promissory note, DHS shall pledge to the
selling Stockholder such shares of Stock being acquired until such time as all
payments due thereunder have been paid in full, provided that such selling
Stockholder shall not be entitled to exercise any voting or other rights with
respect to such shares of Stock so long as DHS is not in default of any payment
due under such note.

                  (c) DEBT DUE FROM STOCKHOLDER.(c) DEBT DUE FROM STOCKHOLDER.
Any debt due by the transferring Stockholder to DHS shall be payable according
to its terms, as shall any debt due by DHS to the transferring Stockholder;
except, however, that, regardless of the terms of any such debt due by the
Stockholder to DHS, any cash payment due under Section 7(a) hereof, as well as
any insurance proceeds payable under Section 8 hereof, with respect to the
purchase of the transferring Stockholder's Stock shall, instead of being paid to
the transferring Stockholder, be first applied to the discharge of any such
indebtedness, until all such

                                       21

<PAGE>

indebtedness is fully discharged. The provisions of this Section 7(c) shall also
apply to any purchases of Stock by DHS pursuant to Section 5 hereof.

                  (d) INVOLUNTARY TRANSFERS. DHS shall settle with an assignee,
trustee in bankruptcy, attaching court or officer or successor in interest
holding Stock received in an Involuntary Transfer by taking any or all such
Stock in execution and paying to them the purchase price for each share of such
Stock calculated pursuant to Section 6, but not exceeding the Stockholder's
indebtedness and proper items of expense. The balance of the value of such
Stock, if any, shall be distributable to the Stockholder with such payments to
be applied in the order due in accordance with Section 7.

                  (e) CLOSING. Closing on the sale of any shares of Stock sold
pursuant to Section 4 of this Agreement shall, unless otherwise agreed to in
writing by the purchaser(s) and the transferring Stockholder, or otherwise
provided in this Agreement, be held at the principal place of business of DHS
(i) thirty (30) days from (A) the date that the last applicable period for
exercising an unexercised option to purchase has lapsed, (B) the date an option
to purchase is accepted or exercised, or (C) with respect to a sale as the
result of the disability of Rifkin or Kimmel pursuant to Section 4(f)(ii), the
date of delivery of the notice required thereunder, or (C) the occurrence of any
event set forth in Section 4(a) (other than death of a Management Stockholder),
or (ii) with respect to the death of a Management Stockholder, ninety (90) days
after the appointment and qualification of a deceased Management Stockholder's
personal representative (collectively, the "CLOSING DATE"); provided that, if an
appraiser or appraisers are appointed to determine the purchase price pursuant
to Section 6, then the Closing shall take place on a date no later than thirty
(30) days from the receipt by the selling Stockholder and the purchaser of the
determination of the fair market value of the Stock if such Closing Date would
occur later than the Closing Date otherwise determined pursuant to this Section
7(e). At the Closing, upon payment of the purchase price (including delivery of
the notes), the certificates representing the Stock to be purchased and sold
hereunder shall be delivered by the selling Stockholder (or his personal or
legal representatives, as the case may be) to the purchaser(s), appropriately
endorsed in blank for transfer. If the certificates representing any shares of
Stock to be so transferred have not been surrendered by the selling Stockholder,
all rights of the holder thereof with respect to said Stock (including voting
rights) nonetheless shall cease and terminate.

                  8. LIFE INSURANCE.

                  (a) PURCHASE AND OWNERSHIP OF POLICIES. As soon as practicable
following the execution of this Agreement, DHS shall use its commercially
reasonable best efforts to purchase a life insurance policy on the life of each
Management Stockholder in such amounts, if any, as DHS' Board of Directors deems
reasonable and appropriate. DHS shall be the owner and

                                       22

<PAGE>

beneficiary of each such policy, and any proceeds received thereunder shall be
held by DHS in trust for the purposes of satisfying DHS' purchase obligations
hereunder. Each Management Stockholder agrees to cooperate with DHS in
obtaining, and in keeping in full force and effect, all such policies. Once a
policy has been purchased, DHS shall maintain all such insurance policies in
full force and effect and shall not, without the prior written consent of the
respective Management Stockholder, cancel any such policy or take or omit to
take any action which might give rise to the termination or cancellation
thereof. DHS shall pay premiums on all insurance policies as they become due.
DHS may, when it deems appropriate, apply any dividends declared and paid on
such policies to the payment of premiums. No party hereto shall have any
obligations hereunder to the extent a Management Stockholder is either
uninsurable or may not be insured as herein contemplated at upon commercially
reasonable terms. Notwithstanding the foregoing, DHS may, in lieu of or in
addition to policies of insurance acquired, owned and administered as set forth
above, in the discretion of its Board of Directors, provide as benefits to its
employees, including Management Stockholders, such other and additional policies
of insurance or other insurance benefit plans on such other or additional terms
and conditions, including ownership of policies of insurance in whole or in part
by employees, including Management Stockholders, as it deems reasonable and
appropriate.

                  (b) Option to Purchase Policies. If a Management Stockholder
transfers all of his Stock during his lifetime pursuant to Sections 4 or 5, or
if this Agreement is terminated without being superseded by a similar agreement
prior to such Management Stockholder's death, such Management Stockholder, or
any designee of such Management Stockholder, shall have the right, during the
sixty (60) day period beginning with the date of transfer or termination of this
Agreement, to purchase any life insurance policy insuring his life owned by DHS
by paying DHS an amount equal to the cash surrender value of such policy
(determined after payment of all policy loans incurred to pay premiums due
thereunder and interest thereon) as of the date of purchase, plus the unearned
portion of any premiums which shall have been paid thereon.

                  9. VOTING BY STOCKHOLDERS.

                  (a) SALE OF STOCKHOLDER'S STOCK. If any vote, consent,
determination or other action is required or permitted to be made by the
Stockholders and/or by DHS pursuant to the terms of this Agreement in order to
authorize and permit DHS to exercise any of its rights hereunder, any
Stockholder who would, upon exercise of said rights by DHS, thereby become
obligated to sell his Stock, shall cast his vote and otherwise act, (i) as a
Stockholder, by voting his stock in the same manner as do the holders of a
majority of shares of Stock other than his own, and, (ii) as a director, by
voting in the same manner as do a majority of the directors other than himself.
A Stockholder who becomes obligated to sell his shares of Stock hereunder shall
execute such instruments as may be necessary or appropriate to effect any action

                                       23

<PAGE>

required or permitted to be taken by the Stockholders and the directors of DHS
pursuant to the terms of this Agreement.

                  (b) CLASS A DIRECTORS. Each of the present and future holders
of Class A Common Stock hereby agrees (i) to vote his shares of Stock to elect
Stewart Gold, Alan Kimmel, and Scott Rifkin, as three of DHS' Class A Common
Stock Directors for as long as their respective Employment Agreements with DHS
are in full force and effect, and (ii) if then serving as a Class A Common Stock
Director, to offer to resign as a director immediately upon termination of his
employment with DHS.

                  (c) ISSUANCE OF ADDITIONAL SHARES OF STOCK. Subject to such
rights of the Series A Preferred Stock Directors pursuant to Article IV, Section
B.1(c) of the DHS Amended and Restated Articles, to such rights of the Series B
Preferred Stock Directors pursuant to Article IV, Section C.1(c) of the DHS
Amended and Restated Articles, to such rights of the Series C Preferred Stock
Directors pursuant to Article IV, Section D.1(c) of the DHS Amended and Restated
Articles, to such rights of the holders of Series A Preferred Stock pursuant to
Article IV, Section B.1(e) of the DHS Amended and Restated Articles, to such
rights of the holders of Series B Preferred Stock pursuant to Article IV,
Section C.1(e) of the DHS Amended and Restated Articles, and to such rights of
the holders of Series C Preferred Stock pursuant to Article IV, Section D.1(e)
DHS Amended and Restated Articles, to exercise their respective rights with
respect to the matters set forth therein, each Stockholder agrees (i) to vote
his or its shares of Stock, (ii) to use commercially reasonable best efforts to
cause his or its Affiliates to vote their shares of Stock, and (iii) if serving
as a Director of DHS, to vote as a Director, to cause DHS to issue additional
shares of stock to the Persons and in the amounts as are necessary:

                           (1) to comply with the provisions of a public
         offering of DHS Common Stock pursuant to a registration statement filed
         with the Securities and Exchange Commission;

                           (2) to fund or comply with the provisions of a stock
         option plan, restricted option plan, employee stock purchase plan,
         stock bonus plan or other employee stock plan or benefit approved and
         implemented by the Board for the benefit of officers, directors or
         employees of DHS, provided that the aggregate numbers of shares issued
         in respect of all such plans shall not exceed ten percent (10%) of the
         fully diluted capital stock of DHS calculated as of the time of the
         issuance and after giving effect thereto;

                           (3) upon conversion of any shares of Convertible
         Preferred Stock;

                           (4) for the acquisition of another corporation by DHS
         by merger, purchase of substantially all of the assets of such
         corporation or other reorganization resulting in the ownership by DHS
         of not less than fifty percent (50%) of the voting power of such
         corporation;

                           (5) as a result of a stock split, stock dividend or
         reclassification of shares of Common Stock distributable on a pro rata
         basis to all holders of Common Stock, with respect to any shares of
         Stock which have been repurchased by DHS and are being resold; and/or

                           (6) to permit BMGGP, Inc., as General Partner of the
         LP, to issue Additional Limited Partner Interests upon acquisition of
         additional Medical Practices from and after the time that there are
         sixty-six (66) physicians who hold Limited Partner Interests in the LP
         (including options to purchase Limited Partner Interests) directly or
         indirectly through their professional corporations.

                  10. SPECIFIC PERFORMANCE. Because the shares of Stock cannot
be readily purchased or sold in the open market, irreparable damage would result
in the event this Agreement is not specifically enforced. Therefore, the rights
to, or obligations of, any party shall be enforceable in a court by a decree of
specific performance, and appropriate injunctive relief may be applied for and
granted in connection therewith. Such remedies, and all other remedies provided
for in this Agreement, shall, however, be cumulative and not exclusive and shall
be in addition to any other remedies which any party may have under this
Agreement or otherwise. Notwithstanding any other provision of this Agreement,
including, without limitation, the provisions of this Section 9, holders of
Convertible Preferred Stock shall have no obligation to vote for any matter
which requires the consent of such Stockholders or of the directors of DHS
elected by them under the Amended and Restated Articles of Incorporation of DHS.

                  11. GUARANTEE OF CERTAIN MANAGEMENT STOCKHOLDERS.

                  (a) Pursuant to the terms and conditions of Gold, Rifkin and
Kimmel's respective DHS Employment Agreements, such Management Stockholders are
each required to secure, or to assist the other officers and employees of DHS in
securing, financing for DHS to satisfy DHS' capital requirements as set forth in
its financial projections. The parties hereto have entered into the transactions
contemplated by the Practice Participation Agreement on the assumption that DHS
would receive cash as a result of equity financing in an amount of not less than
$5 million on or before February 28, 1998 (the "FINAL MATURITY DATE").

                  (b) If DHS does not receive at least $5 million of cash as a
result of equity financing proceeds by the Final Maturity Date, the amount of
equity

                                       25

<PAGE>

financing proceeds actually received by DHS on or before such date shall be
subtracted from $5 million (such positive difference being the "remainder"),
and each of Gold, Rifkin and Kimmel shall present to DHS for cancellation, and
DHS shall immediately cancel that number of shares of Class A Common Stock held
by each such Management Stockholder equal to the product of the number of fully
diluted shares of Class A Common Stock held by such Management Stockholder on
the Closing Date, times a fraction, (i) the numerator of which shall be such
remainder, and (ii) the denominator of which shall be 5 million.

                  (c) Each of the parties hereto acknowledges and agrees that
any transfer of shares of Class A Common Stock pursuant to the provisions of
this Section 11 shall not be subject to the limitations and restrictions on
transfer, and the rights granted to the other Stockholders and DHS with respect
to transfers, as otherwise provided in Section 5 hereof.

                  (d) Each of the Management Stockholders and DHS hereby agree
that the provisions of this Section 11 shall be deemed to be amendments to each
Management Stockholder's respective DHS Employment Agreement, and hereby becomes
a part thereof.

                  (e) For purposes of this Section 11, an equity financing shall
include any transaction in which Capital Stock of DHS is issued in return for
cash.

                  12. SEVERABILITY. It is the express intention of the parties
that the agreements contained herein shall have the widest application possible.
If any agreement contained herein is found by a court having jurisdiction to be
unreasonable in scope or character, the agreement shall not be rendered
unenforceable thereby, but the parties shall in good faith negotiate a
modification to the agreement that preserves the essence of the agreement of the
parties contained herein with retroactive effect to render such agreement
reasonable and such agreement shall be enforced as thus modified. If the court
having jurisdiction will not review the agreement, then the parties shall
mutually agree to a revision having an effect as close as permitted by law to
the provision declared unenforceable. The parties further agree that in the
event a court having jurisdiction determines, despite the express intent of the
parties, that any portion of any covenant or agreement contained herein is not
enforceable, the remaining provisions of this Agreement shall nonetheless remain
valid and unenforceable.

                  13. ENDORSEMENT OF CERTIFICATE. Upon the execution of this
Agreement, each certificate of Stock of DHS now registered in the name of a
Stockholder and subject hereto shall be endorsed by the Secretary of Company as
follows:

                                       26

<PAGE>

                  "This certificate is transferable only upon compliance with
         the provisions of a restrictive agreement dated September 4, 1996, by
         and among Doctors Health System, Inc. and certain of its stockholders,
         a copy of which is on file in the office of the Secretary of DHS and is
         available upon request of any stockholder without charge."

All certificates for any shares of Stock hereinafter issued to Stockholders
shall bear the same endorsement, and this Agreement shall cover all such stock.

                  14. TERM. Anything contained herein to the contrary
notwithstanding, this Agreement shall terminate, and all rights and obligations
shall cease, except for rights and obligations under any then extant promissory
note pursuant to Section 7 hereof, upon the occurrence of any of the following
events:

                  (i) The written agreement of each of the then parties hereto; 
    or

                  (ii) The cessation of DHS' business; or

                  (iii) The bankruptcy, liquidation, receivership, or
    dissolution of, or assignment for the benefit of creditors by, DHS;

                  (iv) Any Change in Control of DHS; or 

                  (v) The consummation of any public offering of DHS Capital 
    Stock.

                  15. NOTICES. All notices, offers, acceptances, requests and
other communications hereunder shall be in writing and shall be deemed to have
been duly given if delivered or mailed by certified or registered mail to a
Stockholder, as may be required, at their addresses on DHS records, and to DHS
at DHS's principal place of business. Any party hereto may change his or its
address for notice by giving notice thereof in the manner hereinabove provided.

                  16. AMENDMENT. Any term or condition set forth in this
Agreement may be amended, modified or altered, and additional terms and
conditions may be incorporated into this Agreement only with the express written
consent of all of DHS and the Stockholders. All of such amendments,
modifications, alterations or additions shall be effective as of the date of
such unanimous consent, shall be in writing, and shall be provided to each of
the parties hereto.

                  17.MISCELLANEOUS. This Agreement embodies the entire agreement
and understanding among the parties hereto with respect to the subject matter
hereof. This Agreement shall be binding upon, and inure to the benefit of, and
shall be enforceable by, the heirs, successors, assigns, and personal
representatives of the parties hereto. This Agreement shall be

                                       27

<PAGE>

governed by, and construed in accordance with, the laws of the State of
Maryland, without regard to principles of conflicts of law. In case any term of
this Agreement shall be held invalid, illegal or unenforceable in whole or in
part, neither the validity of the remaining part of such term nor the validity
of the remaining terms of this Agreement shall in any way be affected thereby.
Each of the parties agrees that he will consent to and approve any amendments of
the DHS Amended and Restated Articles or by-laws of DHS which may be necessary
or advisable in order to conform any of the provisions of this Agreement or any
amendments hereto to the applicable laws of the State of Maryland as now or
hereafter enacted. Each Stockholder agrees to vote his shares of Stock in DHS
and to execute and deliver such documents as may be necessary in order to
implement the provisions of the preceding sentence. Nothing set forth or
referred to herein expressed or implied is intended or shall be construed to
convey upon or give to any person other than the parties and their successors or
permitted assigns, any rights or remedies under or by reasons of this Agreement.
Each of the Stockholders agrees that, if DHS is able to enter into any
arrangement with a Management Stockholder or another Stockholder, regarding the
repurchase of such Management Stockholder's or other Stockholder's capital stock
that is manifestly more favorable to DHS than the arrangements set forth herein,
to execute and deliver to an amendment to this Stockholders Agreement reflecting
such arrangement.

                  18. INTERPRETATION. The parties and their respective legal
counsel and accountants actively participated in the negotiation and drafting of
this Agreement, and in the event of any ambiguity or mistake herein, or any
dispute among the parties with respect to the provisions hereof, no provision in
this Agreement shall be construed unfavorable against any of the parties on the
ground that it or its counsel was the drafter thereof.

                  19. WILLS. Each Management Stockholder shall promptly execute
a will or codicil to his will authorizing and directing his personal
representatives to perform all of his obligations under this Agreement, but the
failure to execute such a will shall not affect the rights of the remaining
Stockholders or the obligations of their personal representatives, heirs,
descendants, or estates, as provided in this Agreement.

                  20.CANCELLATION OF PRIOR AGREEMENT. This Agreement supersedes
and replaces that certain Stockholders Agreement by and among DHS, the
Management Stockholders, the LP, the Series A Investor and the Series B
Investor, dated December 1, 1995 (the "OLD STOCKHOLDERS AGREEMENT") in its
entirety. The Old Stockholders Agreement is hereby cancelled, rescinded and
abrogated.

                              EMPLOYMENT AGREEMENT


                  THIS EMPLOYMENT AGREEMENT, entered into on September 9, 1996
(the "Signing Date") to be effective as of June 5, 1995 (the "Effective Date"),
between DOCTORS HEALTH SYSTEM, INC., a Maryland corporation (the "Company"), and
THERESA SPOLETI (the "Executive").

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

                                   BACKGROUND
                                  -------------

                  The Company is engaged, directly or through service contracts
with others, in the business of (i) negotiating contracts to provide health care
services and products, (ii) managing health care providers and (iii) providing
health care services and products (the "Business").

                  The Executive is experienced in designing and implementing
globally capitated health care products and serving in a leadership capacity in
the administration of health care management.

                  The Company desires to hire Executive, and the Executive
desires to be employed by the Company, on the terms and conditions set forth in
this Agreement.

                  1.       EMPLOYMENT, DUTIES AND ACCEPTANCE.

                           1.1      EMPLOYMENT.

                                    (a) On the Effective Date, the Company shall
employ the Executive as its Vice President of Managed Care Products and
Services. In such capacity, the Executive shall report directly to and be
subject to the supervision and direction of the President and Chief Executive
Officer of the Company (the "CEO"). The Executive shall have overall
responsibility and authority for development and implementation of the managed
care products and services (including network Independent Physician
Associations) offered by the Company. The Executive shall perform her duties
faithfully and to the best of her abilities.

                                    (b) The Executive shall, subject to SECTION
1.1(c) hereof, devote her full working time and creative energies to the
performance of her duties hereunder and will at all times devote such additional
time and efforts as are reasonably sufficient for fulfilling the significant
responsibilities entrusted to her. So 

<PAGE>


long as such activities, in the aggregate, do not interfere with the performance
by the Executive of her duties hereunder: (i) the Executive shall be permitted a
reasonable amount of time to supervise her personal, passive, investments; 
(ii) the Executive shall be permitted a reasonable amount of time to 
participate (as board member, officer or volunteer) in civic, political and 
charitable activities; and (iii) the Executive shall be permitted to deliver 
lectures to and teach at educational institutions and business organizations.

                              1.2 PLACE OF EMPLOYMENT. The Executive's principal
place of employment shall be in the Baltimore, Maryland metropolitan area,
subject to such travel as may be reasonably required by her employment pursuant
to the terms hereof. The Executive shall not be required to relocate outside of
the Baltimore, Maryland metropolitan area during the Term unless the Company
provides relocation benefits.

                  2. TERM OF EMPLOYMENT. The term of the Executive's employment
under this Agreement (the "Term") shall commence on the Effective Date and shall
end on June 4, 1998, unless sooner terminated, or extended, as herein provided.
Not later than April 1, 1998 (and each April 1 of each calendar year during any
Extension Period (defined below)), the Company and the Executive shall enter
into good faith negotiations to determine whether and on what terms to extend or
renew this Agreement beyond June 4 of such calendar year. If by February 1, 1998
(and February 1 of any calendar year occurring during an Extension Period)
either party gives written notice to the other of its desire to terminate this
Agreement as of June 4, then this Agreement shall so terminate, and the
Executive shall be permitted a reasonable amount of time during the balance of
the Term within which to explore alternative employment opportunities. If no
such written notice to terminate is given by either party by February 1, 1998
(or by February 1 of any calendar year occurring during an Extension Period),
then the Term shall, without further act or deed, automatically be extended upon
the same terms and conditions as previously in effect, for an additional 12
month period, commencing on June 5 of the applicable calendar year and ending on
June 4 of the immediately following calendar year. Each such 12 month extension
during the Term is referred to herein as an "Extension Period", and shall
constitute a part of the Term of this Agreement for all purposes, including the
provisions regarding extensions contained in this SECTION 2.

                  3.       COMPENSATION.

                              3.1 SALARY. As compensation for all services to be
rendered pursuant to this Agreement, the Company shall pay to the Executive,
during the Term, a "Base Salary" (as defined in this SECTION 3.1) less such
deductions as shall be required to be withheld by applicable laws and
regulations. The "BASE SALARY" shall be a salary of $110,000 per annum from the
Effective Date to June 4, 1996 and $140,000 from June 5, 1996 to the end of the
Term. The Base Salary shall accrue from and after 


                                      -2-

<PAGE>


the Effective Date, and shall be payable during the Term, in arrears in equal
bi-weekly installments.

                              3.2 BONUS POOL.

                                    (a) Beginning with the calendar year 1996,
the Company shall establish for the benefit of the Executive and certain other
Company employees a "Bonus Pool" with respect to each calendar year, or portion
thereof, that occurs during the Term (each a "Bonus Year").

                                    (b) During the Term, except as otherwise
provided herein, the Executive shall be entitled to participate in the Bonus
Pool to the extent determined by the CEO; provided, however, that the bonus
award which the Executive shall receive for the first Bonus Year shall be an
amount determined with reference to performance criteria set forth in a letter
agreement between the Executive and the Corporation. However, in no event shall
the Bonus exceed 25% of the Base Salary. All amounts allocated to the Executive
pursuant to this SECTION 3.2 shall become payable to the Executive and are
hereinafter collectively referred to as the "Bonus". The amount of the
Executive's Bonus for each Bonus Year, if any, shall be determined by the first
day of March, and paid by the fifteenth day of March, next following the Bonus
Year for which the Bonus is payable.

                              3.3 STOCK OPTIONS.

                                    (a) Upon the adoption by the Company of an
Omnibus Stock Option Plan or other stock benefit plan (the "Plan") which affords
to key employees of the Company the opportunity to participate in the Company's
growth through stock ownership, the Company will grant to the Executive options
(the "Options") to purchase 10,000 shares of the Company's Class A Common Stock
(the "Initial Option Shares"). Additional Option Shares may be granted to the
Executive as described below.

                                    (b) Notwithstanding anything herein to the
contrary, the date of grant (the "Grant Date") of such Options shall be
coincident with the date of adoption of the Plan by the Company, and the
exercise price of such Options shall be determined, as described in greater
detail below, with respect to the fair market value of the Option Shares as of
the Grant Date. As soon as practicable after the Executive is notified by the
Company of such fair market value, but in no event later than three (3) days
following such notification, the Executive shall inform the Company in writing
of the Executive's election to receive "Qualified Incentive Stock Options"
issued under the Plan, or to receive "Non-Qualified Stock Options", whether
under the Plan or otherwise, or some combination of the two as the Executive and
the CEO may reasonably agree.


                                      -3-


<PAGE>


                                    (c) Additional Options (the "Additional
Options") may be issued to you pursuant to the Company's Omnibus Stock Option
Plan from time to time as determined by the CEO. The grant of any Additional
Options shall be subject to and based upon the broad criteria described in
paragraph 3.3(d) of this Agreement and the Additional Options shall have the
effect of providing you the opportunity to own 50 percent of an assumed fully
diluted physician ownership position in the Company (approximately 50 percent of
 .758 percent of the outstanding Common Stock of all classes of the Company). The
Additional Options will be granted upon the successful inauguration of one or
more of the Company's globally capitated products. The Executive will be deemed
to have satisfied this requirement when any physician groups associated with the
Company have any patients (subscribers) directly or indirectly enrolled in
capitation services for the Company providing primary, specialty, ancillary,
acute and subacute care.

                                    (d) All of the Executive's Options shall be
exercisable for a period of ten (10) years from the date they are granted to the
Executive. All shares issued to the Executive pursuant to the exercise of the
Options granted under this SECTION 3.3 shall be subject to the vesting and
forfeiture provisions set forth in this SECTION 3.3. Two-fifths of the Initial
Option Shares shall vest upon the first anniversary of the Effective Date. The
remaining Initial Option Shares shall vest equally during each month from June
5, 1997 to June 4, 2001, so long as the Executive remains employed with the
Company. The Additional Options shall be granted after June 4, 1996 if the
capitation requirements described in SECTION 3.3(c) have been satisfied. The
Additional Options shall vest over a period of five years from the grant date in
equal annual installments on each anniversary of the grant date. Except as
otherwise set forth herein, the Executive shall not be entitled to transfer any
Options, or shares that are subject to forfeiture, until such share has vested
in the Executive. Notwithstanding the foregoing, all Options shall, at the
Executive's election, immediately become exercisable, and all shares shall,
notwithstanding anything to the contrary herein, vest in the Executive and no
longer be subject to restriction or forfeiture, upon occurrence of any initial
public offering of Company securities, a liquidating distribution of the
Company, a combination, consolidation or merger where the Company is not the
survivor, any sale or issuance of Company securities that places a majority of
the voting power of shares in the control of persons or entities not having such
control on the date hereof, or any sale, exchange or other disposition of all or
substantially all of the Company's assets (each a "Change in Control").

                                    (e) The Initial Option Shares and the
Additional Options shall have an exercise price per share equal to (i) in the
case of "Qualified Incentive Stock Options", the fair market value of a share of
the Company's Class A Common Stock as of the Grant Date, as determined by the
Company in good faith, and (ii) in the case of "Non-Qualified Stock Options", an
amount determined by the CEO and the Plan's Committee. The payment of any
exercise price for Options granted to the 


                                      -4-

<PAGE>


Executive hereunder may be made by the Executive in cash or, if the Executive so
requests in writing, by delivery to the Company of a full-recourse promissory
note of the Executive secured by the shares received upon exercise of the
Options. Any such promissory note shall have a term of ten years, shall accrue
(but not be payable until due) interest at the "applicable Federal rate" for
income tax purposes, and shall be subject to mandatory prepayment by the
Executive upon any disposition of shares for cash upon exercise of any Options
or upon any termination of the Executive's employment pursuant to SECTION
4.3(a).

                                    (h) Nothing in this SECTION 3.3 shall

services hereunder for (i) a period of three consecutive months, or (ii) shorter
periods aggregating three months during any twelve month period, the Company may
at any time after the last day of the three consecutive months of disability or

<PAGE>

                                    (a) Notwithstanding any other provision of
this Agreement, the Company may terminate the Executive's employment hereunder
at any time upon: (i) the continued failure or refusal by, or manifest inability
of, the Executive to perform her duties after reasonable prior notice to the
Executive; (ii) the Executive engaging in any acts or omissions involving
dishonesty or acts or omissions that demonstrate a lack of integrity; (iii) the
conviction of the Executive of a felony; (iv) the Executive engaging in acts or
omissions that demonstrably and materially injure the business and affairs of
the Company, monetarily or otherwise; and/or (v) any knowing material
misrepresentation made by the Executive to the Company or any material breach by
the Executive of her obligations hereunder.

                                    (b) In addition to the Company's right to
terminate the Executive's employment pursuant to SECTION 4.3(a), and
notwithstanding any other provision of this Agreement, the Company may, for any
or for no reason, terminate the Executive's employment upon 60 days prior
written notice to the Executive.

                              4.4 TERMINATION BY THE EXECUTIVE.

                                    (a) Provided that the Executive has
delivered to the Company at least sixty (60) days prior written notice setting
forth in reasonable detail any alleged material breach by the Company of this
Agreement or acts or omissions engaged in by the Company constituting
"constructive termination" of the Executive's employment with the Company, which
breach, acts or omissions have not been cured by the Company as of the end of
such period to the reasonable satisfaction of the Executive, then,
notwithstanding any other provision of this Agreement, the Executive shall be
entitled to terminate her employment for such reasons, effective immediately
upon the delivery by the Executive to the Company of a notice to the effect that
such breach, acts or omissions have not been cured to the reasonable
satisfaction of the Executive; provided, however, that if such constructive
termination is caused by the Executive's incapacity or inability to serve due to
a disability of the type described in SECTION 4.2 above and the Company elects
to terminate the Executive pursuant to the provisions of SECTION 4.2, the
Executive shall, for purposes of this Agreement, be deemed to have been
terminated pursuant to the provisions of SECTION 4.2 and not of this SECTION
4.4.

                                    (b) For purposes of this SECTION 4.4,
"constructive termination" shall be limited to those circumstances where (i) the
Company creates working conditions that a reasonable person in the Executive's
position would consider unreasonable or intolerable which is not remedied by the
Company within sixty (60) days after notice thereof given by the Executive; and
(ii) such working conditions are not generally applicable to other executives of
the Company.

event of termination due to death (SECTION 4.1) or Disability (SECTION 4.2), any
Options that remain unexcercised and any shares of stock that remain unvested

event of termination due to death (SECTION 4.1) or Disability (SECTION 4.2), any
Options that remain unexcercised and any shares of stock that remain unvested
pursuant to SECTION 3.3 shall immediately be excercisable by the Executive (or
her heirs, legatees and/or legal representatives), and fully vested in the
Executive, and upon issuance all such shares shall be subject to the Company's
Stockholders Agreement then in effect.

                                    (b) In the event of termination of the
Executive's employment pursuant to SECTION 4.3(b) or SECTION 4.4 (each a
"WRONGFUL TERMINATION"), the Executive (or, in the event of the Executive's
subsequent death or disability, her heirs, legatees and/or legal
representatives) shall receive (i) all accrued Base Salary and benefits (if any)
then payable to the Executive pursuant to the terms of any plans or arrangements
referred to in SECTION 3.5; (ii) as liquidated damages, an amount equal to the

contractual employment term then in effect in equal monthly installments or, at
the election, of the Company in a lump sum; and (iii) subject to the provisions
of the Company's Amended and Restated Articles (as in effect on the date
hereof), the Company's By-laws (as in effect on the date hereof), the
Stockholder's Agreement, and, if issued under a Plan, any Plan then in effect,
any Options that remain unexcercised and any shares of stock that remain
unvested pursuant to SECTION 3.3 shall immediately (and thereafter) be fully
excercisable and vest in the Executive and no longer be subject to forfeiture.
Any amounts then outstanding under any Promissory Note referred to in SECTION
3.3 above shall remain due and payable to the Company in accordance with the
terms of such Promissory Note.

                                    5.4.2 CONFIDENTIAL INFORMATION DEFINED. Any
other information not qualifying as a Trade Secret, but relating to the business
of the Company which is disclosed by the Company to the Executive, or is
discovered by the Executive in the course of employment, is Confidential
Information.

                                    5.4.3 DUTY TO MAINTAIN SECRECY AND
CONFIDENTIALITY. During the Period of the Executive's employment with the
Company, the Executive shall maintain the secrecy and confidentiality of the
Trade Secrets and the Confidential Information and shall not (i) divulge,
furnish or make accessible to anyone or in any way or use, for her own benefit
or for the benefit of any other individual firm or entity (other than in the

                                    5.4.4 INFORMATION WHICH IS PUBLICLY KNOWN.
Notwithstanding anything herein to the contrary, the obligations of secrecy and
confidentiality set forth herein shall not apply to any information which is now
generally publicly known or which subsequently becomes generally publicly known
other than as a direct or indirect result of the breach of this Agreement by the
Executive, or which is required by law or order of any court to be disclosed.

                              5.5 PROPERTY OF THE COMPANY. All memoranda, notes,
lists, records and other documents or papers (and all copies thereof), including
but not


                                      -11-

<PAGE>


limited to, such items stored in computer memories, on microfiche or by
any other means, made or compiled by or on behalf of the Executive, or made
available to the Executive concerning the Company Business, are and shall be the
property of the Company and shall be delivered to the Company promptly upon the
termination of the Executive's employment with the Company or at any other time
on request; provided however, that the Executive may inspect during normal
business hours such records as shall be necessary for the purpose of assisting
the Executive to file, or prepare for an audit of, her personal income tax
returns.

                              5.6 EXECUTIVE'S IDEAS, ETC. All inventions,
prototypes, discoveries, improvements, innovations and the like ("Inventions")
and all works of original authorship or images that are fixed in any tangible
medium of expression and all copies thereof ("Works") which are designed,
created or developed by Executive, solely or in conjunction with others, in the
course of performance of the Executive's duties which relate to the Company
Business, shall be made or conceived for the exclusive benefit of and shall be
the exclusive property of the Company. The Executive shall immediately notify
the Company upon the design, creation or development of all Inventions and
Works. At any time thereafter, the Executive, at the request and expense of the
Company, shall execute and deliver to the Company all documents or instruments
which may be necessary to secure or perfect the Company's title to or interest
in the Inventions and Works, including but not limited to applications for
letters of patent, and extensions, continuations or reissues thereof,
applications for copyrights and documents or instruments of assignment or
transfer. All Works are agreed and stipulated to be "works made for hire," as
that term is used and understood within the Copyright Act of 1976, as amended.
To the extent any Works are not deemed to be works made for hire as defined
above, and to the extent that title to or ownership of any Invention or Work and
all other rights therein are not otherwise vested exclusively in the Company,
the Executive shall, without further consideration but at the expense of the
Company, assign and transfer to the Company the Executive's entire right, title
and interest (including copyrights and patents) in or to those Inventions and
Works.

                              5.7 RIGHTS AND REMEDIES UPON BREACH. If the
Executive breaches, or threatens to commit a breach of, any of the provisions of
SECTIONS 5.1 through 5.6 (the "Restrictive Covenants"), the Company shall, in
addition to its right immediately to terminate this Agreement, have the right
and remedy (which right and remedy shall be independent of others and severally
enforceable, and which shall be in addition to, and not in lieu of, any other
rights and remedies available to the Company under law or in equity) to have the
Restrictive Covenants specifically enforced by any court having equity
jurisdiction, it being acknowledged and agreed that any such breach or
threatened breach could cause irreparable injury to the Company or its
Affiliates and that money damages may not provide adequate remedy to the
Company.


                                      -12-

<PAGE>


                              5.8 COVENANTS CURRENTLY BINDING EXECUTIVE. The
Executive warrants that her employment by the Company will not (a) violate any
non-disclosure agreements, covenants against competition, or other restrictive
covenants made by the Executive to or for the benefit of any previous employer
or partner, or (b) violate or constitute a breach or default under, any statute,
law, judgment, order, decree, writ, injunction, deed, instrument, contract,
lease, license or permit to which the Executive is a party or by which the
Executive is bound.

                              5.9 LITIGATION. There is no litigation, proceeding
or investigation of any nature (either civil or criminal) which is pending or,
to the best of the Executive's knowledge, threatened against or affecting the
Executive or which would adversely affect her ability to substantially perform
the duties herein.

                              5.10 REVIEW. The Executive has received or been
given the opportunity to review the provisions of this Agreement, and the
meaning and effect of each provision, with independent legal counsel of the
Executive's choosing.

                              5.11 SEVERABILITY OF COVENANTS. The Executive
acknowledges and agrees that the Restrictive Covenants are reasonable and valid
in geographical and temporal scope and in all respects. If any court determines
that any of the Restrictive Covenants, or any part thereof, is invalid or
unenforceable, the remainder of the Restrictive Covenants shall not thereby be
affected and shall be given full effect, without regard to the invalid portions.

                              5.12 BLUE-PENCILING. If any court determines that
any of the Restrictive Covenants, or any part thereof, is unenforceable because
of the duration or geographic scope of such provision, such court shall have the
power to reduce the duration or scope of such provision, as the case may be,
and, in its reduced form, such provision shall then be enforceable and shall be
enforced. If any such court declines to so revise such covenant, the parties
agree to negotiate in good faith a modification that will make such duration or
scope enforceable.

                              5.13 ENFORCEABILITY IN JURISDICTIONS. The parties
intend to and hereby confer jurisdiction to enforce the Restrictive Covenants
upon the courts of any jurisdiction within the geographical scope of such
Covenants. If the courts of any one or more of such jurisdictions hold any
Restrictive Covenant unenforceable by reason of the breadth of such scope or
otherwise, it is the intention of the parties that such determination not bar or
in any way affect the Company's right to the relief provided above in the courts
of any other jurisdiction within the geographical scope of such Covenants, as to
breaches of such Covenants in such other respective jurisdictions, such 
Covenants as they relate to each jurisdiction being, for this purpose, severable
into diverse and independent covenants.


                                      -13-

<PAGE>


                              5.14 EXTENSION. If the Executive violates any
Restrictive Covenant, the Company shall not be deprived of the full benefit of
the period of the covenant. Accordingly, the duration of that covenant shall be
extended by the period of any violation of that covenant.

                              5.15 REMEDIES. The Company shall be entitled to
injunctive or other equitable relief because it will be caused irreparable
injury and damage by a breach of the provisions of any of the Restrictive
Covenants. The right to injunctive relief shall include the right to both
preliminary and permanent injunctions. The Company shall not be required to post
a bond or other similar assurance if it brings an action to enforce the
provisions of any of the Restrictive Covenants. The Company's right to equitable
relief shall not preclude any other rights or remedies which the Company may
have, all of which rights and remedies are cumulative.

                  6. DISPUTE RESOLUTION.

                              6.1 COSTS OF LITIGATION. If either party files
suit or brings an arbitration proceeding to enforce its rights under this
Agreement, the prevailing party shall be entitled to recover from the other
party all expenses incurred by it in preparing for and in trying the case,
including, but not limited to, investigative costs, court costs and reasonable
attorney's fees.

                              6.2 CONSENT TO JURISDICTION. The parties submit to
the jurisdiction and venue of the courts of the State of Maryland.

                              6.3 NO JURY TRIAL. NEITHER PARTY SHALL ELECT A

                              ARBITRATION PROCEDURE

1.       INSTITUTION OF ARBITRATION PROCEEDING.

         1.1. Any party to this Agreement (an "Initiating Party") may initiate
an arbitration proceeding (the "Proceeding") to resolve a dispute subject to
resolution under this Schedule (a "Dispute") by giving written notice (the
"Dispute Notice") to the other party (the "Responding Party") to such Dispute.
The Dispute Notice shall describe the substance of the Dispute with sufficient
specificity to give the Responding Party adequate notice of its nature. Unless
otherwise specified, time periods specified in this Schedule 6.4 shall be
calculated from the date of the Dispute Notice (the "Commencement Date").

2.       SELECTION OF ARBITRAL PANEL.

         2.1. The Arbitral Panel (the "Panel") shall consist of three
arbitrators, two of whom (the "Party Designated Arbitrators") shall be selected
by the parties pursuant to SECTION 2.2 hereof. The third arbitrator shall be a
"Neutral Arbitrator" selected by the Party Designated Arbitrators pursuant to
SECTION 2.3 hereof.

         2.2. The Initiating Party shall designate its Party Designated
Arbitrator in the Dispute Notice. Within fifteen days of the Commencement Date,
the Responding Party shall designate its Party Designated Arbitrator.

         2.3. Within forty-five days of the Commencement Date, the two Party
Designated Arbitrators shall agree upon and appoint a Neutral Arbitrator who
shall be an accountant and a partner in an international, "Big Six" accounting
firm.

         2.4. Each party agrees promptly to disclose to the other party any
circumstances known to it which would cause reasonable doubt regarding the
impartiality of an individual under consideration or appointed as the Neutral
Arbitrator and any such individual shall also promptly disclose to the parties
any such circumstances.

         2.5. During the process of selecting the Neutral Arbitrator and
thereafter during the course of this Proceeding, ex parte communications with
the Neutral Arbitrator or any individual under consideration as the Neutral
Arbitrator are prohibited and shall be disclosed by the party making any ex
parte communication, the Neutral Arbitrator or any individual under
consideration as a Neutral Arbitrator immediately upon discovery.

3.       PRE-HEARING PROCEDURES.

         3.1. Within fifteen days of the appointment of the Neutral Arbitrator,
the Panel may convene a Pre-Hearing Conference to, inter alia, familiarize the
Neutral Arbitrator with the nature of the Dispute between the Parties, determine
the need for and the nature of discovery and establish a procedural schedule for
the further conduct of the Proceeding.

4.       DISCOVERY.

         4.1. Discovery, appropriately limited by the nature of the Dispute, is
expressly contemplated and permitted. However, the Parties acknowledge and agree
that one of the benefits of resolving Disputes through arbitration is the
opportunity reasonably to limit discovery. The Parties further agree that they
will endeavor to agree upon procedures and a schedule for discovery that will
result in a prompt and fair hearing under these procedures.

         4.2. Discovery requests and responses need not be served upon the Panel
but the Panel shall promptly convene upon motion of either party to resolve
discovery disputes, if any.

         4.3. Discovery will be completed within sixty days of the Pre-Hearing
Conference.

5.       SUBMISSION OF EVIDENCE AND HEARING.

         5.1. The Panel may receive evidence in the form of written statements
filed prior to Hearing for cross-examination on such statements or may receive
oral testimony at Hearing. Each party shall be entitled to submit rebuttal
testimony. The Panel may also permit opening and closing statements of counsel
at Hearing.

         5.2. The Panel shall convene for Hearing the evidence and argument of
the parties at a time and place to be established by the Panel. The Hearing
shall be held no later than thirty days after the close of discovery or thirty
days after the Pre-Hearing Conference if there is no discovery.

         5.3. At the Hearing, and for all other purposes related to the
Proceeding, the Initiating Party shall be deemed the party seeking affirmative
relief, shall go first and shall bear the burdens of proof and of persuasion.

         5.4. The Hearing shall be transcribed.


                                      -19-

6.       POST-HEARING PROCEDURES.

         6.1. The Panel may request Post-Hearing briefs and, if it does so,
shall establish a schedule for submission of such briefs at the close of
Hearing.

         6.2. Within thirty days of the later of the close of the Hearing or its
receipt of Post-Hearing briefs, the Panel shall issue a written Decision and
Award which shall include findings of fact and explain the reasons for the
Decision.

7.       CONFIDENTIALITY.

         7.1. Unless otherwise agreed, the Proceeding and all information and
documents relating to it shall be kept confidential by the Parties, the Panel,
witnesses and all other persons involved with the Proceeding. Specifically, but
without limitation, the Confidential Information of the parties shall be
safeguarded and maintained as confidential by all participants in the
Proceeding.

8.       COSTS.

         8.1. The Neutral Arbitrator's fees and expenses, and all expenses of
the Pre-Hearing Conference, Hearing or any other aspect of the Proceeding not
directly attributable to either party, such as the cost of transcription of
Panel Hearings and rental of Hearing rooms, shall be borne equally by the
parties.

         8.2. The Panel shall in its Decision and Award determine whether and to
what extent either party is a prevailing party and entitled to an award of its
costs, including attorneys' fees.

9.       MISCELLANEOUS.

         9.1. The parties may agree at any time to depart from these procedures,
including the time periods herein established. Although not favored, the Panel
may also permit departures from these procedures and time periods absent
agreement of the parties to prevent a miscarriage of justice.

         9.2. Until the Neutral Arbitrator is appointed, any issue relating to
the Proceeding that is not provided for in these procedures shall be governed by
the Commercial Arbitration Rules of the American Arbitration Association. Once
the Neutral Arbitrator is appointed, the Panel is empowered to resolve all
issues not contemplated by these procedures and upon which the parties cannot
agree.


                                      -20-

<PAGE>

         9.3. The Panel may grant any remedy or relief that it deems just and
equitable and within the scope of the agreement of the parties, including, but
not limited to, specific performance of a contract, injunctive relief or other
equitable relief.

         9.4. These procedures contemplate a two-party Proceeding. If there are
more than two parties to a Proceeding, and they are unable by unanimous
agreement to align themselves as two parties, each party shall be entitled to
all the rights of a party hereunder, including specifically but without
limitation the right to appoint a Party Designated Arbitrator, and the Neutral
Arbitrator shall have a number of votes as to all matters decided by the Panel
equal to the sum of (i) the votes of all Party Designated Arbitrators, and (ii)
one.

         9.5. The Panel may, in its discretion, convene and act by conference
call for all purposes other than taking oral testimony.

                          FREE STATE HEALTH PLAN, INC.
                             IPA SERVICE AGREEMENT


         This  Agreement  is made and  entered  into on the 1st day of  November
1995, by and between Free State Health Plan, Inc., a corporation organized under
the laws of the  State of  Maryland,  (hereinafter  referred  to as  "HMO")  and
Doctors  Health  System,  (hereinafter  referred  to as "IPA"),  a legal  entity
organized under the laws of the State of Maryland and performing the function of
an  individual   practice   association  as  described  in  the  Federal  Health
Maintenance   Organization  Act  of  1973,  as  amended,   and  the  regulations
promulgated thereunder.

         WHEREAS,  HMO is in Maryland a state  licensed and federally  qualified
health   maintenance   organization   under  the  Maryland  Health   Maintenance
Organization Act and the Federal Health Maintenance  Organization Act of 1973 as
amended; and

         WHEREAS,  IPA is an individual practice association which has as one of
its  objectives  the  delivery or  arranging  for the  delivery of basic  health
services to those who enroll in the HMO (hereinafter called "Members"); and

         WHEREAS,  IPA has entered into  arrangements  or contracts  with health
professionals,  a majority of whom are licensed to practice medicine, surgery or
osteopathy in the State of Maryland; and

         WHEREAS, IPA desires to enter into a written service agreement with HMO
to arrange for the provision of basic health services to the Members of the HMO.

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
promises  herein  stated,  it is agreed by and  between  the  parties  hereto as
follows:

                               Article I - GENERAL

         A.    Purpose.  The purpose of the HMO is to offer prepaid  health care
benefits  through a coordinated system of  arrangements  with  health  care
providers  that  will  afford a  reasonable  choice  of  primary  care
physicians,  assure  access to medical  services and health care  resources  and
monitor the quality of health care provided to the HMO subscribers and their
families, in groups or as individuals.

         B.    HMO  Service  Area.  Subject to  approval  by the U.S. Department
of Health and Human  Services ("DHHS") and the Maryland  Department of Health
and Mental  Hygiene,  and subject to the HMO's  ability to arrange for the
services, the service area will consist of the entire State of Maryland.

         C.    IPA Service Area. The service area  designated (see Attachment A
for detailed  description) is used as an enrollment  guideline by the HMO and as
the criteria  by which an  emergency  room visit will be  categorized  as
in-area or out-of-area.  The HMO will screen  applications  to determine the
ability of the applicant to use the IPA  properly and  efficiently.  The
applicant's  place of residence,  place of employment,  marital status and
access to transportation to the IPA will be considered in the screening process.

         D.    Relationship  of IPA and HMO. Each party to this Agreement
retains its own identity and full  autonomy in carrying out its responsibilities
under the Agreement and in the  management of its affairs. Neither party shall
act as the agent or employee of the other party except as specified in this
Agreement. Except  as  specifically  provided  herein, neither  the  IPA

<PAGE>

nor  the  HMO is authorized  to bind the other with third parties.  Neither  the
IPA nor the HMO shall be liable to any other  party for any act, or failure to
act, of the other party to this Agreement.

         E.    Malpractice  Liability.  Neither the IPA nor HMO shall be liable
for the expense of defending any action for alleged professional malpractice
against the other,  or for any costs  resulting from the loss of such lawsuit.
Both HMO and IPA agree for  themselves,  their  successors and assigns that if
the act of one results in any claim, demand, loss, damage or liability upon or
to the other then,  and in that event,  the party  whose act causes  such claim
or  liability shall  indemnify  and hold harmless the other party which is made
or held liable thereby.  However,  neither the IPA nor the HMO limits its right
to file a cross or  counterclaim or implead the other as a third party defendant
in such a suit. It shall be the  responsibility  of the IPA,  each  physician
and other  health professional  who is an  independent  contractor  with the IPA
to  maintain,  in force, policies of malpractice as described in Article IV,
Section O herein.

                            Article II - DEFINITIONS

Board certified or Board  eligible in a medical or surgical  sub-specialty)  who

entered into an  arrangement  with IPA to  provide  certain  specialist  health
services  to Members.

agreement with IPA to accept referrals of Members from Primary Care Physicians
and provide certain specialist services.

         F.    "Emergency  Services" - means those health care  services  that
are provided in a hospital  emergency  facility  after the sudden onset of a
medical condition that manifests  itself by symptoms of sufficient  severity,
including severe pain, that the absence of immediate medical attention could
reasonably be expected by a prudent  layperson,  who possesses an average
knowledge of health and medicine, to result in:

                  1.       Placing the patient's health in serious jeopardy;
                  2.       Serious impairment to bodily functions; or

                       Article III - HMO RESPONSIBILITIES

         A.  Administration  of  Agreement.  The HMO  agrees to  perform or have
performed  all  necessary   accounting,   marketing,   enrollment,   information
management, data reporting and other functions appropriate to the administration
of the HMO and this Agreement. However, the internal administrative tasks of the
IPA necessary to support  their  responsibilities  under this  Agreement and all
functions  relating  thereto  shall  be  performed  by the  IPA.  Allowance  for
administrative  costs  are  included  in the  capitation  payment  set  forth in
Attachment B, Compensation to IPA, annexed hereto.

         B.  Benefit  Determinations.  The  HMO  retains  authority  and
responsibility,   after  appropriate consultation  with IPA,  to make all
benefit  determinations.  All  communication  to  Members  regarding  benefit
determinations,  bills,  and other  matters  relating  to the HMO  shall be made
by HMO  exclusively.  All  benefit determinations and communications with
Members shall be made by HMO in a timely fashion.

         C.  Medical  Services - Exclusive  Domain of IPA.  The HMO agrees not
to  intervene  in any manner in the  rendition of medical  service by the IPA,
it being agreed that the IPA shall have the sole  responsibility  in connection
therewith and that nothing contained herein shall interfere with the
professional  relationship between an HMO Member and his/her  Physician.  Under
no  circumstances  shall a decision by HMO to deny benefits  hereunder (pursuant
to Article III. B.) be deemed an interference with the relationship between HMO
Member and Physician.

         D.  Collection of Premiums and Other Income.  The HMO agrees to collect
all premiums  and other items of income to which the HMO is entitled  except for
any  copayments  which may be required  of Members at the time of service.  Such
copayments,  if any,  will be collected by IPA when medical  services  requiring
copayments are rendered. Cancellation of enrollment for persons who fail to make
copayments will be solely at discretion of HMO. HMO agrees to give consideration
to recommendations by IPA related to disenrollment.

         E.  Coordination of Benefits. IPA shall establish and implement a
system for  coordination of benefits in accordance with those rules  established
under HMO's Group  Medical and  Hospital  Service  Agreement.  IPA shall
identify and inform HMO of Members for whom coordination of benefits
opportunities exist. HMO hereby authorizes IPA to seek payment, on a
fee-for-service  basis or otherwise, from  any  insurance  carrier,
organization,  or  government  agency  which  is primarily  responsible for the
payment or provision of professional  Health Care Services  provided by IPA
under this Agreement  which can be recovered by reason of  coordination  of
benefits,  motor vehicle  injury,  workmen's  compensation, temporary
disability,  occupational disease, or similar exclusionary or limiting
provisions,  to the extent  authorized by Medical and Hospital Service Agreement
and not otherwise prohibited by law. For other services which are Plan Benefits,
HMO shall seek such  payments.  Both parties agree to exchange  coordination  of
benefits  information  on  Members  in a manner  that will  allow  each party to
maximize coordination of benefits recoveries under this Section.

         F.  Compensation  to  IPA.  The  amount  and  conditions  of all
compensation  to be paid to the IPA during the term of the contract are set
forth in Attachment B annexed hereto.

         G.  HMO  Medical  Director.  For the  purposes of  determining benefits
to be provided by IPA to HMO Members under this Agreement,  HMO shall appoint a
Medical  Director who will perform the following  functions,  in consultation
with IPA's Medical Director:

<PAGE>

                  1.       Review and approve existing  referral  procedures and
documentation of those procedures for Specialty Physician services prior to the
signing of and any changes to this Agreement;

                  2.       Review and approve  existing  criteria and
procedures  comprising a Quality  Assurance, peer and utilization review system
for IPA prior to the signing of and any changes to this Agreement;

                  3.       Review and  approve,  for the  purposes  of  payment,
all elective hospital admissions,  outpatient surgery, DME, home health or any
other equipment or services  paid by HMO directly  (not  covered by
capitation).  IPA agrees that all elective admissions shall be pre-certified and
authorized by the HMO  Medical  Director  prior to  admission,  and that the
cost of any  elective inpatient  hospital  admission made without being
pre-certified may be deducted from  subsequent  capitation  payments  to IPA or
recovered  by any other means necessary.  HMO shall  give IPA not less than
thirty  (30) days  prior  written notice  of its  intent  to  deduct  the cost
of such  hospital  admissions  from capitation  payments to IPA,  during  which
period the parties  will attempt to resolve any dispute related to such proposed
deduction.  The sanctions provided for under  this  paragraph  3 shall  not be
invoked  by HMO in cases  where the uncertified  elective  inpatient  hospital
admission  is  found  to  have  been appropriate,  unless IPA's failure to
obtain precertification  becomes recurring and habitual in which case said
sanctions will be applied;

                  4.       Review qualifications for all providers utilized by
IPA;

                  5.       Serve as Chairman of the Medical Advisory Committee;

                  6.       Monitor ongoing  compliance of IPA providers with
procedures and practices  approved by Medical Advisory Committee;

                  7.       In consultation  with IPA, HMO Medical  Director
shall have final   authority  to  select  and  contract  with  Physician
Specialists  and Consultants  for  services  not covered by  capitation  but for
which IPA shares risk; and

                  8.       Any  approval  by HMO's  Medical  Director  required
under  paragraphs  1 and 2 of this Section III G shall not be unreasonably
withheld or unreasonably delayed.

         H.  Public  and  Governmental  Relations.   The  HMO  shall  be  solely
responsible for the advertising and promotion, public relations and governmental
requirements  relating  to  this  Agreement,   specifically  including  assuring
compliance with applicable laws and regulations relating to the organization and
operation of the HMO. Such  requirements  shall include the  satisfaction of all
reporting  requirements to State and Federal agencies and organizations insuring
the  solvency  of the HMO.  The IPA  shall  provide  the HMO with all  necessary
information  on a timely basis to meet such  requirements  and  otherwise  fully
cooperate  in  assuring  ongoing   compliance  with  operational  and  reporting
requirements of regulatory agencies.

         I.  HMO's Professional  Liability And Other Insurance.  HMO, at its
sole cost and expense,  shall procure and maintain such policies of general
liability and professional  liability  insurance and other insurance as shall be
necessary to insure HMO and its employees  against any claim or claims for
damages arising by reason of personal  injuries or death  occasioned  directly
or  indirectly in connection  with the  performance of any service by HMO, the
use of any property and facilities or equipment provided by HMO, and the
activities performed by HMO in connection with this Agreement.  Memoranda of the
above insurance policies as well as all  reinsurance and insolvency  policies,
if any, shall be provided to IPA upon IPA's request.

<PAGE>

HMO shall notify IPA of any malpractice  claims against HMO  initiated  by
Members who have  selected IPA as their  primary  provider of care.

         J.  Notifications.  The  parties  agree  that each will  promptly
notify the other in the event of any of the  following,  and that upon any such
event,  either  party may,  but shall not be required  to,  terminate  this
Agreement upon thirty (30) days' prior written notice to the other:

                  1.       failure to maintain insurance required under this
Agreement;

                  2.       withdrawal  or  suspension  of, or  failure to renew,
or notice of intent to  withdraw, suspend,  or fail to renew a  certificate  of
authority to operate as a health  maintenance  organization  from the Insurance
Commissioner of the State of Maryland, or any other appropriate State authority;

                  3.       dissolution,  termination of existence,  insolvency
or business failure of either party, commission of an act of bankruptcy by, or

         K.  Benefit  Statements.  HMO will  provide IPA with a concise  summary
benefit description for each type of group and individual Member agreement under
which IPA will be requested to render services under this Agreement. The summary
statements will identify Covered Services,  any and all copayments,  deductibles
or other charges and payments,  and all  exclusions,  limitations  or conditions
applicable to Covered Services.  Summary  statements will be replaced or updated
if  modifications or amendments are made in the agreements to which they relate.
HMO will supply IPA with copies of the group and  individual  Member  agreements
and any and all  amendments,  modifications  and revisions  thereto to which the
summary statements relate.

         L.  Utilization  Reports.  HMO agrees to provide  IPA with  information
relevant to IPA generated by HMO's management  information  systems upon request
by IPA. IPA shall provide a list of requested  reports to HMO  periodically  and
HMO  shall  use best  efforts  to  provide  such  reports  without  cost to IPA;
provided,  however,  if incremental costs are incurred in HMO for the generation
of any such report, HMO and IPA shall mutually agree on reasonable reimbursement
therefor.

         M.  Facilities  List. HMO agrees to provide IPA with a list of approved
health  care  providers,  hospitals,  skilled  nursing  facilities,  home health
agencies, hospices and other health care facilities, which list shall be amended

to the requirements of Article IV, Section F. The HMO reserves the right, at its
sole  discretion,  to  forbid  the  use  by IPA of a  particular  consultant  or
specialty  physician from treating HMO members.  The IPA will pay Consultant and
Specialty  Referral  Physicians  for services  rendered  and obtain  appropriate
patient encounter data from such Consultant or Specialty  Referral Physician for
IPA records and for  reporting to the HMO. HMO shall  provide IPA with a current
list  of  consultants  or  specialty  physicians  selected  by  HMO  to  provide

appropriate or necessary.

         H.  Compensation  from HMO  Solely.  IPA shall  look  solely to HMO for
compensation for Covered Services  provided  hereunder and shall at no time seek
compensation from Members for such services, except for the copayments permitted
under the Medical Health  Benefits  Certificate and Hospital  Service  Agreement

provision  shall survive the  termination  of this  Agreement  regardless of the
cause of such termination.  IPA agrees that all benefit  determinations shall be
made by HMO and in a timely manner.

         L.  IPA Medical Director.  IPA shall provide a physician who shall
serve as Medical  Director at each of IPA's  Health  Center(s).  The duties of

         M.  Administrative  and  Support  Staff.  IPA  shall  provide  adequate
administrative   and  support  personnel  for  IPA  Physicians,   monitoring  of
coordination  of  benefits,  and  patient  satisfaction.  IPA will,  at its sole
expense, engage nurses, technicians,  other non-physician support personnel, and
clerical and administrative  personnel reasonably required by IPA to perform its

         O.  Malpractice Insurance and Liability.  IPA shall provide and
maintain such policies of  malpractice  insurance as shall be necessary to
insure IPA and those health professionals who are its employees against any
claim or claims for damages arising by reason of personal  injuries or death
occasioned  directly or indirectly in connection with the performance of any
service by IPA. The amounts and extent of such  insurance  coverage shall be at
minimum at least one million dollars  ($1,000,000)  per  occurrence  and three
million  dollars  ($3,000,000) aggregate. Any reduction in such coverage shall
require the approval of the HMO, such  approval not to be  unreasonably
withheld.  IPA further  agrees that each Physician and other health professional
contracting with IPA shall provide HMO copies of such policies of malpractice
insurance as shall be necessary to insure such Physicians and other health
professionals  and their employees against any claim or claims  for damages
arising  by reason  of  personal  injury or death occasioned  directly or
indirectly in connection  with the

<PAGE>

performance  of any service by Physician or other health  professional.  IPA
shall notify HMO of any malpractice claims pending against the IPA initiated by
HMO Members. The HMO may at its sole discretion  confirm with the IPA's
malpractice  carrier any of the aforementioned HMO malpractice claims.

         P.       Roster of  Providers  and  Credentialing.  IPA agrees to
maintain on record with the HMO a current schedule of the Physicians and other
providers and to provide HMO a curriculum  vitae,  specifying at least the
physician's  name, specialty and board status,  Maryland  license  number,
location where services will be provided,  hospital  affiliation,  relationship
to IPA, and malpractice history,  and  otherwise  comply  with  HMO's
credentialing  requirements.  The schedule is annexed hereto as Attachment F.
The IPA will use reasonable  efforts to notify the HMO thirty (30) days prior to
any  additions,  deletions  or other changes  to the  information  provided
pursuant  to this  paragraph.  With  the exception  of  malpractice  history,
IPA  agrees  that  HMO may  publicize  the information contained in this roster
to all Members and prospective Members.

                  The  HMO  at  its  direction  may  delegate  to  the  IPA  the
credentialing function for the IPA's physicians.  The IPA is then responsible to
notify  the  HMO  promptly  of any  differences  or  changes  from  the  initial
information  provided.  The HMO has the right to  perform  (and IPA will  allow)
audits of the credentialing process of the IPA.

                  Except  as  permitted  herein,   HMO  shall  not  include  any
description of IPA or of its facilities, services or health professionals or any
reference  to IPA,  direct  or  indirect,  in any  HMO  marketing  materials  or
communications  to Members or  prospective  Members  without  the prior  written
approval of IPA which approval shall not be unreasonably withheld or delayed.

         Q.       Physician  Requirements and  Responsibilities.  It is mutually
agreed that IPA and its Physicians will adhere to the following requirements:

                  1.  All Physicians shall be duly licensed to practice
medicine or  osteopathy  in the State of Maryland.  Evidence of such  licensing
shall be submitted to HMO upon request. In addition,  Physicians, where
appropriate, must meet all  qualifications and standards for membership on the
medical staff of at least one of the hospitals  which has contracted  with HMO
and shall be required to maintain staff  membership and full admission
privileges in accordance  with the rules and  regulations  of such  hospital and
be acceptable to such hospital and successfully  qualify under HMO's physician
credentialing  process. Any IPA Primary,  Specialty or Consultant  Physician,
employed or contracted,  who have their privileges revoked, suspended,  abridged
or restricted in any way, for any reason,  are forbidden from treating any HMO
Members upon  notification from the HMO. HMO shall enter into  arrangements to
obtain hospital  services for Members with certain hospitals to be mutually
agreed upon by IPA and HMO. A list of such hospitals shall be published in
membership materials;

                  2.  Physicians  will have,  where  appropriate,  a current
narcotics  number  issued by the appropriate authority;

                  3.  Except in cases of  emergency  or medical  necessity,  IPA
agrees to use only those  health care  providers,  inpatient,  skilled  nursing,
hospitals and other  facilities which have contracted with HMO. The HMO will not
pay for  non-capitated  services when referred by IPA to providers or facilities
with  which the HMO does not have a valid  contract  and which do not  appear on
HMO's list of contracted  providers and  facilities as amended from time to time
unless specifically  approved in writing by HMO. Said list is attached hereto as
Attachment  L. Within these  limitations,  IPA will attempt to  accommodate  the
requests of Members as to their choice of health professional or facility;

<PAGE>

                  4.  HMO and IPA  together,  shall  from  time to time  jointly
review  methods and details of staffing  and  scheduling  to ensure  appropriate
access at all times.

                  5.  An IPA  Physician  will be  forbidden  from  treating  HMO
Members should health care services  provided by that Physician be determined to
be  sub-standard  by the  credentialing  process,  the HMO  Quality  Improvement
Committee  or  the  HMO  Peer  Review   Committee.   Physician  may  appeal  the
determination through the Grievance Procedure,  an individual copy of which will
be furnished upon request.

         R.  Specification  of Facilities and Hours of Operation.  IPA agrees to
maintain such  facilities for such hours of operation as specified in Attachment
G annexed  hereto.  With the exception of any increase in its hours of operation
(which shall  nonetheless be communicated  to HMO), any additions,  deletions or
other  changes in  facilities  or their  hours of  operation  by the IPA must be
communicated to HMO in writing ninety (90) days prior to becoming effective. HMO
Members  will not be  authorized  to receive  care at such  facilities  prior to
approval  by HMO.  IPA shall  treat HMO Members on an equal basis with its other
patients  which shall be  consistent  with  community  HMO standards for waiting
times and service  access.  This  includes  the IPA  providing  at its costs all
handicap  access  as  required  by  federal  and  state   regulations   such  as
interpretation services for the hearing disabled.

         S.  Administrative,  Accounting,  and Medical Records -
Confidentiality. Physicians  and other  health  professionals  shall  maintain
adequate  medical records for Members  treated by IPA Physicians  and other
health  professionals. Subject to all applicable privacy and confidentiality
requirements, such medical records shall be made available to each Physician and
other health professionals treating the Member, and upon request to any proper
committee of the IPA or HMO, for review to determine  whether  their content and
quality are  acceptable,  as well as for peer  review or  grievance  review.
IPA and HMO agree that  medical records of Members  shall be treated as
confidential  so as to comply  with all Federal and State laws and regulations
regarding the confidentiality of patient records.  HMO, however,  shall have the
right, upon written request, to inspect, at all reasonable  times,  any
accounting,  administrative  and medical records maintained  by IPA  pertaining
to HMO,  to Members  and to IPA's  participation hereunder subject to all
confidentiality requirements.  IPA and HMO agree that a request  pursuant to
this  Article  IV,  Section R shall be in writing and shall identify the records
or information to be reviewed.  HMO shall, upon the request of IPA,  provide IPA
with access to HMO accounting,  administrative  and medical records  pertaining
solely to IPA's  participation in HMO and pertaining to the general  performance
of HMO.  Under no  circumstances  shall IPA have access to information  or
records  of any type  which  pertain  to the  participation  or performance  of
providers  other than IPA. IPA further agrees that, in the event an  examination
concerning  the quality of health care services is conducted by the appropriate
State  officials,  as required by State law, IPA and Physicians shall submit in
a timely fashion,  any required books and records and facilitate in every way
such examination.

         T.  Complaint and Grievance  Procedure.  IPA shall cooperate with HMO
in HMO's  complaint  and  grievance  procedure  and shall  abide by such
grievance procedure,  a copy of which is annexed  hereto as Attachment E. It is
understood that claims which relate to IPA and are subject to  resolution  by
the HMO under the grievance procedure may, in accordance with the terms of this
Agreement,  be charged  to IPA after  full  investigation  under the  complaint
and  grievance procedure.  HMO has the  right  to  recover  payment  of  these
claims  through reduction of capitation payments.  The IPA shall submit to the
HMO complaint and grievance  information to meet the  requirements  of DHHS and
other  appropriate regulatory  agencies.  Medical  information  shall  be
provided  to the  HMO as appropriate and without  violation of pertinent State
and Federal laws regarding the  confidentiality  of medical  records.  HMO's
grievance  procedure  is also available to IPA for purposes of  requesting
disenrollment  of a  non-

<PAGE>

compliant Member  (including  but  not  limited  to one who  consistently  fails
to make copayments)  or  challenging  a  benefit determination.   HMO  agrees
to  give consideration  to  recommendations  by IPA related to  disenrollment
or benefit determinations.

         U.       Physician-Patient  Relationship  Maintained.   Physicians
shall  maintain  the  relationship  of physician  and patient with Members,
without  intervention  in any manner by HMO or its agents or  employees,  and
Physicians  shall be solely  responsible for all medical advice to and treatment
of Members and for the performance of all medical  services  set forth in
Attachment  C, in  accordance  with  accepted  professional  standards  and
practices.

         V.       Physician/Member  Ratios.  IPA  shall,  at all  times,
maintain  a sufficient  number of IPA  Physicians  who are primary care
physicians so as to ensure  there  shall be at  least  one  full-time
equivalent  primary  care IPA Physician  for  each  1,800  Members,  adjusted
for  demographics  of  enrolled membership  at the health  center.  IPA agrees
to comply with HMO  policies  and protocols  for the  use of  mid-level
practitioners  and  the  availability  of physicians during health center hours
of operation and after hours coverage. Any changes in these policies and
protocols  shall be communicated by the HMO to the IPA at least thirty (30) days
prior to their implementation.

         W.       General  Compliance  Requirements.  In  addition  to the
services  to be  rendered by the IPA as described above,  the duties of the IPA
hereunder shall include (1) planning and conducting  systematic peer review
relating to utilization and quality of care rendered by its Physicians,
including  establishment of an appropriate enforcement  mechanism  for all final
peer review and quality  assurance  decisions of IPA in a manner  approved by
HMO (such  approval  not to be  unreasonably  withheld or delayed)  and in
accordance  with  applicable  state and federal  law;  (2)  consultation  with
HMO with  regard  to the  subjects  of  recordkeeping,  review  storage  and
retrieval;  implementation  of a discharge  planning  system for Members
admitted to hospitals under contract with HMO; (3) consultation with HMO
regarding better contact and more complete working  relationships  among the
various entities  involved in HMO's  program and the  community;  (4)
consultation  with HMO and advice with regard to the special  characteristics
and problems of the IPA and HMO as a prepaid health care plan; and (5)
cooperation  with the HMO in collection of Coordination of Benefits, Subrogation
and Workmen's Compensation recoveries.

         X.       Compliance  With HMO Policies and  Procedures and
Consequences  of Non-Compliance.  IPA recognizes HMO's right to establish
administrative policies and  procedures  and  agrees  to be  bound  by them as
well as  comply  with all applicable state and federal laws and regulations
pertaining to the practice of medicine  and  Health  Maintenance  Organizations.
HMO  will  consult  with IPA concerning any significant proposed changes in
HMO's administrative policies and procedures prior to implementation of such
policies and procedures.

                  HMO  agrees  to  compensate   IPA  in  the  event  any  policy
implemented   hereunder   results  in  IPA  incurring   significant   additional
administrative expenses. Significant additional administrative expenses shall be
defined as expenses  which exceed  $1,000 per  contract  year.  Such  additional
expenses shall be proven to HMO's  satisfaction  and shall be  reimbursable in a
manner mutually agreeable to the parties.  In the event IPA fails to comply with
HMO  Administrative  Policies  and  Procedures  and  continues  to do  so  after
receiving   fifteen   (15)  days  notice  in  writing   from  the  HMO  of  such
non-compliance,  HMO shall have the right to withhold up to ten percent (10%) of
the  capitation  owed to IPA  each  month  until  such  non-compliance  has been
resolved or action to resolve  such  non-compliance  has been  initiated.  HMO's
right or resort to this remedy shall not act as a limitation  on any other right
of HMO, all such rights and remedies being cumulative.


<PAGE>

         Y.       Effects of Complaints/Malpractice.  IPA agrees to remove a
physician from the roster of physicians  servicing HMO Members in the event said
physician is the object of recurring Member complaints adjudicated in favor of
complainant according to HMO's grievance procedures and/or malpractice claims
adjudicated in favor of the complainant by the Maryland Health Claims
Arbitration Office or by a court of competent jurisdiction.

         Z.       Compliance with HMO Quality  Improvement Program and
Consequences of Non-Compliance.  IPA recognizes HMO's right to establish
quality  assurance and service standards and agrees to be bound by them. These
standards are set out in Attachment  J and will be amended by HMO from time to
time.  In the event IPA or an individual  physician  (primary care or
specialist)  fails to comply with HMO Quality  Improvement  Program and
continues to do so after receiving thirty (30) days notice in writing from HMO
of such non-compliance,  then HMO shall have the right to  withhold up to ten
percent  (10%) of the  capitation  owed to IPA each month  and/or  restrict a
physician  from use by the IPA in treating HMO Members until  such
non-compliance  has  been  resolved  or  action  to  resolve  such
non-compliance  has been  initiated.  HMO's right or resort to this remedy shall
not act as a limitation on any right of HMO, all such rights and remedies  being
cumulative.

         AA. Non-Payment of Authorized  Services.  When IPA authorizes a service
for  which it is  financially  responsible  and the  provider  of said  services
invokes its statutory right to recover  directly from HMO of said services,  and
IPA fails to make payment  therefor  within a reasonable  time,  HMO may pay for
said  services and deduct the amount paid from future  payments to IPA under the
following circumstances:

                  1.       After HMO has ascertained that the service was
authorized;

                  2.       The person or entity  rendering said service is
attempting to collect  payment  directly from the IPA and has provided IPA with
proof of past due status of the debt; and

                  3.       The  service  was  provided  at least  sixty  (60)
days  prior to any such  attempt  at collection.

                  HMO shall  apprise IPA in writing at least  fifteen  (15) days
prior to exercising this right.

         BB. Compliance with Annotated Code of Maryland, Health General Article,
Section  19-713.2.  IPA agrees to establish  an Escrow Fund,  obtain a Letter of
Credit,  or otherwise  insure funds  availability  sufficient  to satisfy  IPA's
obligations to external  providers as defined in the Annotated Code of Maryland,
Health General Sec. 19-713.2  effective July 1, 1991. IPA also agrees to provide
HMO with a paid claims  analysis which defines those external  obligations,  and
will provide, on a monthly basis,  throughout the term of this Agreement, a paid
claims  report  which  will  enable  HMO to monitor  IPA's  compliance  with the
Annotated Code of Maryland,  Health General Sec. 19-713.2. IPA further agrees to
comply with all terms and conditions of the Annotated  Code of Maryland,  Health
General Sec. 19-713.2, and any regulations promulgated pursuant thereto.

         CC. HMO-USA.  The HMO is affiliated with a collaboration  of Blue Cross
Blue  Shield  HMO  Plans,  herein  referred  to as  HMO-USA.  These  Plans  have
established  arrangements  to  provide  certain  medical  services  for  Members
traveling into another Plan's service area. The IPA agrees to participate in the
HMO-USA  network and provide the same level and type of care for HMO-USA members
as that  required  by  this  Agreement  for the  HMO's  Members.  This  includes
arranging for all specialty care when necessary.  The HMO will reimburse the IPA
or their  contractual  specialty or  consultant  physicians  using the HMO's

<PAGE>

fee schedule.  Under this program,  the IPA shall not seek compensation from
HMO-USA members for such services, including copays.

                  Article V - JOINT OBLIGATIONS OF IPA AND HMO

         A.       Cooperation  and  Liaison.  IPA and HMO  shall  maintain
effective liaison and close  cooperation  with each other to provide  maximum
benefits to each Member at the most reasonable  cost  consistent  with quality
standards of medical  practice.  IPA and HMO shall cooperate to control
enrollment in HMO in order to avoid exceeding the reasonable capacity of
personnel and facilities.

              Article VI - FINANCIAL ARRANGEMENTS AND RISK SHARING

         A.       Maintenance  of Records.  The HMO and IPA will maintain
records of account  for  all  financial  transactions   pertaining  to  the
HMO.  Billing, collection,   receipt  and   reconciliation  of  all  revenues
and  appropriate disbursement  of required  monies will be recorded and
maintained in accordance with  accepted  accounting  practices.  The IPA will
also  provide  the HMO with Audited  Financial  Statements  including  all
notes,  schedules,  and  auditor opinions on an annual basis  within  fifteen
(15) days of receipt from the audit firm or 180 days from the end of the fiscal
period, which ever occurs sooner. If the IPA fails to submit the Audited
Financial  Statements  by the scheduled due date,  the HMO shall have the right
to apply the sanctions  described in Article IV, Section X, unless IPA requests
an extension of such due date which shall not be unreasonably withheld or
delayed.

         B.       Risk  Sharing.  As  an  incentive  to  control  the  cost  to
HMO  of  providing   non-capitated (underwritten)  services under this
Agreement,  the IPA and HMO shall share risk for the cost of these services in
the manner set out in Attachment B.

         C.       State of  Maryland  Performance  Standards  Penalties.  The
State of Maryland employer group contract contains  specific  performance
standards that carry financial penalties for noncompliance. It is agreed that
should the HMO be assessed penalties by the State of Maryland due to the IPA's
failure to meet any or all of the aforementioned  standards then IPA will be
charged an amount equal to those  penalties  associated  with  their  HMO
Members  via a  reduction  in capitation  payments.  See Attachment K for a
listing of these  performance  and noncompliance penalties.

            Article VII - TERM OF AGREEMENT, TERMINATION AND RENEWAL

         A.       Term. The [initial] term of this Agreement shall be November
1, 1995 through  December 31, 1996. Both parties commit to initiate  negotiating
in good faith to  produce a new  Agreement  not less  than  ninety  (90)  days
prior to termination of this current Agreement. If, at the termination of this
Agreement, a new Agreement has not been signed, both parties agree to abide by
the terms of this  Agreement  until the new Agreement is  consummated  or for a
period not to exceed three (3) months after termination,  whichever is less. The
parties agree that if it is the  intention  of either not to renew this
Agreement  or to seek renewal on terms significantly  different from those
specified herein, then said party  shall give the other  party a minimum of
ninety  (90) days prior  written notice of same before the end of this Term.

         B.       Termination.  This Agreement may be terminated by either HMO
or IPA at any time, if written  notice is given at least ninety (90) days in
advance of such termination.  [, except during an initial term when termination
may only be for cause,  which is defined as the breach of a term,  condition or
provision of this Agreement.] Upon such termination, the rights of each party
hereunder shall terminate,  provided  however,  that such action shall not
release either HMO or IPA of  obligations  imposed  with  respect  to: (i) third
party  payors;  (ii)

<PAGE>

incentive  payments accrued to IPA or penalty payments due HMO (see Risk Sharing
Article VI. B.) in  connection  with existing  contracts under the HMO program;
(iii) the  obligation of IPA to persons then  receiving treatment;  or (iv) the
obligation  of IPA to look  solely  to HMO for  payment and not to  attempt  to
collect  payment  from any  Members.  The  parties agree  that in the  event of
voluntary termination,  as provided herein, the obligations of HMO and IPA shall
continue in full force and effect at the capitation rate in force at the time of
termination for the period  remaining on group and individual  Member  contracts
existing on the date notice of termination  is given to IPA or received by HMO.
HMO and IPA agree that such extension of IPA  obligations  hereunder  shall not
include  obligations arising out of the renewal of  existing  Member  contracts
which become effective after the date notice of termination under this Agreement
is given or the execution of new Member  contracts which become  effective after
the date written notice of termination is sent to IPA or received by HMO.

                  This Agreement may be terminated upon the filing by HMO or IPA
of a voluntary  petition  in  bankruptcy  or a  voluntary  petition or an answer
seeking reorganization,  arrangement, readjustment of its debts or for any other
relief under any bankruptcy or insolvency act or law of any jurisdiction, now or
hereafter  existing,  or any action by either party  indicating  its consent to,
approval  of,  or  acquiescence  in,  any  such  petition  or  proceeding;   the
application by either party for, or the  appointment by consent to  acquiescence
of, a receiver or trustee of either party for all or a  substantial  part of its
property;  the  making by  either  party of an  assignment  for the  benefit  of
creditors;  the  inability of either party or the admission by either in writing
of its inability to pay its debts as they mature;  the  voluntary  suspension of
business by either party.

                  This  Agreement  may  be  terminated  upon  the  filing  of an
involuntary   petition   against   either   party  in   bankruptcy   or  seeking
reorganization,  arrangement,  readjustment of its debts or for any other relief
under  any  bankruptcy  or  insolvency  act or law of any  jurisdiction,  now or
hereafter existing;  or the involuntary  appointment of a receiver or trustee of
either party for all or a substantial part of its property, or the issuance of a
warrant of attachment, execution or similar process against any substantial part
of the property of either  party and the  continuance  of the same  undismissed,
undischarged,  or  unbonded  for a period of sixty days;  then,  and in any such
event,  the other party may declare,  by written notice,  that this Agreement is
automatically terminated.

                          Article VIII - MISCELLANEOUS

         A.       Binding  Effect.  This  Agreement  shall be binding  upon and
inure to the benefit of the parties hereto,  their respective heirs,  successors
and assigns, and it may not be assigned,  subcontracted,  or otherwise delegated
in a manner  inconsistent  with this  Agreement by either party without the
prior written  consent of the other party except as otherwise provided herein.

         B.       Headings.  The headings of the various  sections of the
Agreement  are  inserted  merely for the purpose of convenience  and do not,
expressly or by  implication,  limit or define or extend the specific terms of
the section so designated.

         C.       Maryland Law To Govern.  The validity,  enforceability  and
interpretation of any of the clauses of this Agreement shall be determined and
governed by the laws of the State of Maryland.

         D.       Independent  Contractor  Status.  None  of the  provisions  of
this Agreement is intended to create nor shall be designed or construed to
create any relationship  between  IPA and HMO  other  than  that  of
independent  entities contracting  with each  hereunder  solely for  effecting
the  provisions of the Agreement.   Neither  of  the  parties  hereto  nor  any
of  their

<PAGE>

respective representatives   shall  be  construed  to  be  the  agent,  the
employer,   or representative of the other.

         E.       Costs.  In the  event of a  dispute  between  HMO and IPA
regarding  the  interpretation  of the contractual  provisions  contained in
this by one party  against the other then and in that event the party against
whom judgment is rendered agrees to pay the reasonable legal expenses and
reasonable court costs of the other.

         F.       Agreement  Complete.  This  Agreement  contains  all the
terms and  conditions  agreed on by the parties hereto,  and supersedes all
other  agreements,  oral or otherwise,  regarding the subject matter or parties
hereto.

         G.       Amendments.  This  Agreement  may be  amended  at any time by
mutual  agreement  of the  parties, provided that before any amendment  shall be
operative and valid,  it shall be reduced in writing and signed by the HMO and
IPA. Said  amendments  may be added in the form of  additional  attachments,
signed by both parties,  when other specific provisions are added or modified.

         H.       Notice.  Any notice  required to be given  pursuant to the
terms and  provisions  hereof shall be in writing and shall be sent by certified
mail, return receipt requested, prepaid, to HMO at:

                       Free State Health Plan, Inc.
                       c/o CFS Health Group, Inc.
                       100 S. Charles Street, Tower II, Sixth Floor
                       Baltimore, Maryland 21201

and to IPA at:         Doctors Health System
                       10451 Mill Run Circle, 10th Floor
                       Owings Mills, Maryland  21117

         I.       Confidentiality of Agreement. The parties acknowledge that the
terms and  conditions  of  this  agreement  are of a most  sensitive  nature
and,  if disclosed,  could be very damaging with respect to their  competitive
position. Therefore,  the parties  agree that  neither  shall  disclose  the
terms of this Agreement  (including  attachments)  without  the prior  written
consent of the other.  Any such disclosure  shall be deemed a material breach of
this Agreement and shall be cause for immediate  termination of this Agreement
at the option of the non-breaching party.

         J.       Recoupment for Incorrect  Payments.  If, at any time during
the term of this Agreement,  HMO determines that it has made an incorrect
overpayment to IPA or on IPA's  behalf,  HMO shall have the right,  after giving
the IPA thirty (30) days prior written notice, to recover from IPA the full
amount  incorrectly overpaid.  Such  recovery may be in the form of set off,
withholding  of future payments, or demand for repayment. HMO's right or resort
to these remedies shall not act as a limitation on any other right of HMO to
recover  overpayments  from IPA by any other means, all such means being
cumulative.

                  If  during  the  term of this  Agreement  IPA  determines  and
demonstrates to HMO's satisfaction that it has received an underpayment pursuant
to the terms of this  Agreement,  then HMO shall remit to IPA said  underpayment
within thirty (30) days of said demonstration.

         K.       Effect on Affiliates.  The terms of this Agreement  shall
apply,  at HMO's sole  election,  to any health  maintenance  organization  or
other entity related to or affiliated  with

<PAGE>

HMO,  including but not limited to Blue Cross and Blue  Shield of  Maryland,
Inc.,  its  subsidiaries, affiliates,  and  related entities.

         L.       HMO  as  Licensed  Controlled   Affiliate.   IPA  hereby
expressly acknowledges  its  understanding  that this  Agreement  constitutes  a
contract between IPA and HMO that HMO is an  independent  corporation  operating
under a license  from the Blue Cross and Blue  Shield  Association,  an
association  of independent Blue Cross and Blue Shield Plans (the
"Association"), permitting HMO to use the Blue Cross and Blue Shield  Service
Mark in a portion of the State of Maryland,  and that the HMO is not contracting
as the agent of the  Association. IPA further  acknowledges and agrees that it
has not entered into this Agreement based  upon  representations  by any  person
other than HMO and that no person, entity,  or organization  other than HMO
shall be held  accountable or liable to IPA for any of HMO's obligations to IPA
created under this

<PAGE>


Agreement. This paragraph shall not create any additional obligations whatsoever
on the part of HMO other than those  obligations  created under other provisions
of this Agreement.

         IN  WITNESS   WHEREOF,   the   parties,   by  their   duly   authorized
representatives,  have executed this  Agreement the day and year set forth below
their signature to be effective as stated in Article VII hereof.

                                IPA SERVICE AREA




For  purposes  of  this  Agreement,  the  service  area  for  use by the  HMO as
guidelines in enrolling Members and to define in-area and out-of-area  emergency
room visits shall be as follows:





<PAGE>


                                  ATTACHMENT B

                       CAPITATION/FINANCIAL ARRANGEMENTS


1. Capitation will be paid on or near the 15th day of each month according to
   the schedule in this Attachment for Members who are enrolled in the HMO for
   such month, and who have affirmatively selected the entity identified as IPA
   in this contract as their selected Primary Provider. A summary listing
   showing enrolled Members by the categories relevant to level of reimbursement
   will be provided with the payment check. Also on the listing will be a
   calculation of any retroactive adjustments either adding or deleting Members
   enrolled in the IPA. IPA shall be liable for the cost of any care required to
   be provided to any Member who selects IPA as his/her Primary Provider. This
   liability includes the cost of any specialty care given after a Member's
   effective date with IPA in accordance with a referral made by a Member's
   previous Primary Provider. Liability for the cost of care shall continue
   until receipt of notice from HMO of the Member's ineligibility for coverage.

2. The period covered by this Attachment B will be from November 1, 1995 through
   December 31, 1996. During this period, in consideration of said capitation
   amounts, the IPA shall provide or arrange for all those health care services
   set forth in Attachment C, and shall assume the responsibility for the cost
   of said services (as defined in the HMO Member contracts attached to this
   Agreement). Regardless of the number of IPA Physicians rendering services, if
   any, to a Member during any month, only one capitation payment will be made
   to IPA each month for each Member. The capitation payment shall be made
   regardless of the type or amount of service rendered to the Member during a
   given month.

3. CAPITATION SCHEDULE (Per Member Per Month)
   ------------------------------------------

   Contract Type/Description
   -------------------------

   Most Prevalent Coverages       Copay             Capitation PMPM
   ------------------------       -----             ---------------

   Advantage I, II, III            $0       [Confidential Treatment Requested]
       and Blue Plus
   Direct Pay                      20%      [Confidential Treatment Requested]
   Medicare Supplemental           $0       [Confidential Treatment Requested]

* The zero copay capitation rates PMPM for all coverages are reduced
[Confidential Treatment Requested] for each dollar of office copay,
respectively.

   Capitation amounts (present and future) shall be adjusted (increased or
   decreased) to reflect future copayment and benefit changes depending on
   whether such changes result in increased or decreased liability or revenues
   to IPA. See item 5 for discussion of "Opt-Out" products.

4. Underwritten and Institutional Services (UIS) Pool
   --------------------------------------------------

   The following services are considered included in the Underwritten and
   Institutional Services Pool:

   a.  Inpatient Hospital
   b.  Other Underwritten Services
            Out of Area Emergency, including Facility, Physician and Related
            Services
            Skilled Nursing Facility
            Hospice
            Ambulance
            Shock Trauma (Institutional only)
            Extracorporeal Lithotripsy
            Outpatient Surgery Facility Fees at Licensed Facilities
            Abortions

   Funding of the UIS Pool beginning November 1, 1995 through December 31, 1996
   will be [Confidential Treatment Requested] per member per month to cover the
   benefits discussed above. It is agreed that due to the nature of the product
   Members enrolled in self-funded Opt-Out products will be excluded from any
   UIS Pool Settlement.

   At the end of the contract term, after allowing a 120-day grace period for
   late submission of charges, a settlement relating to cost sharing will be
   calculated. The total dollars paid into the UIS Pool during the applicable
   period (including recoveries from Subrogation and COB related to UIS
   services) will be added and then all monies expended during the period for
   services covered under the Pool will be deducted leaving a net amount
   [Confidential Treatment Requested]. If there is a surplus (positive balance)
   in the Pool, then that amount will be allocated [Confidential Treatment
   Requested] between HMO and IPA. If a deficit (negative balance) exists, then
   IPA will be given notice of the projected amount due from it. IPA will be
   liable for [Confidential Treatment Requested] of the deficit up to a maximum
   amount equal to [Confidential Treatment Requested] of the capitation
   received. Payment of amounts resulting from the cost sharing of the UIS Pool
   will be made within 30 days from delivery of settlement from HMO to IPA. It
   is understood that for products that are self-funding for the services
   detailed, above, there will be no UIS Pool or settlement. See Attachment H
   for an example of the risk sharing calculation.

5. Participation in HMO's Opt-Out Products
   ---------------------------------------

   As a means of inducing persons to transition from indemnity type insurance to
   the HMO managed-care-type health plan, HMO has several opt-out products;
   e.g., New Choice, Blue Plus. These products allow Members to "opt out" of the
   HMO's provider network at the time service is rendered or selected. Such an
   election is discouraged by the imposition of substantial copays.

   IPA agrees to participate in these programs on the following bases:

   IPA shall provide the same level of services to Members electing HMO's
   opt-out products as with traditional HMO Members with the understanding that
   although such Members are required to select a Primary Care Physician and
   site at the time of enrollment they, nonetheless, may choose to obtain
   services from Physicians other than those to whom they may be referred by
   IPA's providers.

   In return for IPA's rendering of said services, HMO shall compensate IPA
   [Confidential Treatment Requested] of the capitated amounts previously
   specified in Section 3 of this Attachment.

   A separate non-UIS opt-out cost pool (referred herein as "Pool") will be
   established relative to the opt-out Members. The Pool shall be funded by the
   remaining [Confidential Treatment Requested] capitation and an additional
   amount matching the [Confidential Treatment Requested] capitation.

   Amounts expended by HMO for capitated services (Not UIS services; all UIS
   costs for these Members except self-funded products are included in the UIS
   Pool described on Page 2 of this Attachment) rendered by providers to whom
   Member has not been referred by IPA (i.e., non-capitated professional
   services) shall be separately identified and applied against the amounts
   funded in the Pool.

   Any cost or savings, i.e., any difference in the Pool, shall be shared
   between HMO and IPA [Confidential Treatment Requested].

   There will be no UIS Pool for Members enrolled in self-funded opt-out
   products.

6. HMO agrees to compensate Doctors Health System on a fee-for-service basis

                        CAPITATION HEALTH CARE SERVICES


The IPA  agrees  to  provide  the  following  medical  services  (to the  extent
specified in the benefit summaries provided by HMO) to each HMO Member selecting
assignment  to the IPA for the  capitation  payment as set forth in Attachment B
and to collect applicable copayment amounts from the HMO Member depending on the
contract in effect between HMO and its Members.  The IPA is responsible  for the
services  contained  within this  Attachment C resulting  from any  precertified
hospital  admissions  regardless  of whether they occur inside or outside of the
IPA or HMO Service areas and for any in area emergency  admissions.  Out-of-area
emergency  admissions  are paid by the HMO and included in the UIS pool. The IPA
is also  responsible  to notify the site where a newborn is being  enrolled  (if
different  from the  mother's)  during the  mother's  stay in order to  transfer
financial  responsibility  for any  neonatal  care,  otherwise  the IPA  will be
responsible  for any costs during the baby's stay  including UIS charges.  It is
agreed that services  required by government  regulatory bodies such as OSHA are
the financial responsibility of the regulated employers and not the HMO.

VI.      Emergency In-Area

         Emergency  Services  means those health care services that are provided
         in a hospital  emergency  facility  after the sudden onset of a medical
         condition  that  manifests  itself by symptoms of sufficient  severity,
         including severe pain, that the absence of immediate  medical attention
         could reasonably be expected by a prudent  layperson,  who possesses an
         average knowledge of health and medicine, to result in:

                  1.       Placing the patient's health in serious jeopardy;
                  2.       Serious impairment to bodily functions; or
                  3.       Serious dysfunction of any bodily organ or part.

         In consideration of the capitation  payments set forth in Attachment B,
         IPA shall  provide  or make  available  Health  Care  Services  for the
         treatment of emergency  conditions on a  24-hours-a-day,  7-days-a-week
         basis.  The IPA will be  financially  responsible  for those  emergency
         services  that are provided in the Service Area (See  Attachment A) and
         the IPA has preauthorized, authorized at the time of Member's access to
         care or would have  authorized  the  service  in the  normal  course of
         events  based  upon a  retrospective  review  in  accordance  with  HMO
         procedures.  The IPA is  financially  responsible  for the facility and
         professional  charges except when a Member is directly and  immediately
         admitted to the hospital  following an emergency  department  visit, in
         which case the  emergency  room  facility  charge shall be deemed to be
         inpatient charges and shall not be the financial  responsibility of the
         IPA. The IPA is financially  responsible for any differential between a
         Member's  office and emergency  copay when the emergency room encounter
         results  from a lack of  coverage on the IPA's part as required by this
         Agreement.

VII.     Optional Benefits and Services

         Certain  optional  health  services  may be  purchased  from HMO for an
         increased premium.  If agreed to by IPA, such optional services will be
         rendered without charge except for applicable copayments. If IPA agrees
         to  provide  one  or  more  optional  services,  HMO  will  pay  IPA an
         agreed-upon  capitation  rate for each Member  entitled to receive such
         optional  service(s).  In the event IPA and HMO agree  upon one or more
         optional services,  such agreement shall be in writing signed on behalf
         of the  parties  hereto and shall be attached  hereto and  incorporated
         herein.

VIII.   Referrals for Psychiatric Care and Care for Alcohol and Drug Addiction

         IPA shall provide appropriate  referrals for specialty psychiatric care
         and treatment for Alcohol and Drug Addiction.

IX.      Braces and Splints

         Braces,  defined as a device to support a body part  through a range of
         normal   motion.   A  brace  is  provided  only  under  the  Prosthetic
         Devices/Durable Medical Equipment Rider.

         Splints, defined as fitted devices which restrict normal motion.

         Covered splints include:

<PAGE>


         A.       Splints necessary for  post-operative  healing which are
                  applied by a physician during the immediate post-operative
                  period.

         B.       Splints that are molded, fitted and supplied by a physician in
                  his or her office.

         See Paragraph XI of this Attachment C for a copy of the  responsibility
         matrix detailing examples of these items.

X.       Cardiac Surgery

         The following services are to be provided  exclusively by University of
         Maryland Medicine:

                  Cardiac Catheterization (CATH)
                  Percutaneous Transluminal Coronary Angioplasty (PTCA)
                  Coronary Artery Bypass Graft (CABG)

         The  HMO  will  adjudicate  these  claims  and  charge  the IPA for the
         physician component via capitation reduction. The costs remaining which
         the HMO pays will be included in the UIS Pool.  The amounts  associated
         with these  services  will be  provided by the HMO  separate  from this
         document.

         Note:  This  Section X will be amended  to  reflect  the impact fo the
         new  University  of  Maryland  Cardiac Services arrangement.

Dear Terry:

The purpose of this Letter of Intent is to describe the terms of the contracting
agreements to which we have agreed, each of which will be included in a Medicare
Risk  Service  Agreement  between  Doctors  Health  System (DHS) and Health Care
Corporation  of  the  Mid-Atlantic  ("HCCMA").   The  following  terms  will  be
incorporated  (and changes made) in the Medicare Risk Service  Agreement (a copy
attached)  which is used as the  basic  contract  form by HCCMA;  the  resulting
document to be the Medicare Risk Service  Agreement  between HCCMA and DHS, (the
"Agreement").  Until the basic contract revisions are finalized,  this Letter of
Intent will serve as the written contract between HCCMA and DHS.

      (bullet) Term

         (bullet) February 1, 1996 - June 30, 1997. Otherwise, termination will
                  only occur for cause.  Should the  Agreement  not be  renewed,
                  obligations  under the  Agreement  shall  continue  beyond the
                  termination  date for an  additional  period not to exceed six
                  (6) months.

      (bullet) Financial Terms

                  DHS to submit  proposals  to provide  such  services  to HCCMA
                  Medicare  Members enrolled with DHS.  However,  such proposals
                  will not be  considered if the  enrollment  of HCCMA  Medicare

                  objective  of which will be to limit the UIS Pool fund  amount
                  held by HCCMA to no more  than the  projected  cost of  ninety
                  (90) days expected claims.

         (bullet) [OMITTED AND FILED SEPARATELY WITH THE COMMISSION]

         (bullet) HCCMA  agrees  that,  in the event a Member is  retroactively
                  added  more  than 90 days to  DHS's  panel,  DHS  will  not be
                  financially  responsible  for the cost of any care  which that
                  Member   received   for  the  period  prior  to  the  90  days
                  retroactive limit and HCCMA will retain the full AAPCC payment
                  from the Federal  Government  for such a Member for the period
                  prior to the 90 day retroactive  limit.  DHS providers will be
                  paid by HCCMA  at HCCMA  fee  schedule  rates  for the cost of
                  covered services that they directly provide.

                  design involving provision of medical care under the Agreement
                  will be communicated to DHS in advance of marketing.  DHS will
                  have the option to consider this as cause for termination and,
                  as such may opt to terminate the Agreement as a result of such
                  material/substantive  product  design changes with ninety (90)
                  days notice,  in writing,  to HCCMA and in accordance with the
                  other terminating provisions of the Agreement.

         (bullet) HCCMA agrees to work with DHS to allow greater  participation
                  by DHS in decisions or oversight  regarding  matters involving
                  pre-certification,  utilization management and case management
                  of institutional services.

         (bullet) DHS agrees to  support to the  maximum  extent  possible  the
                  marketing efforts of HCCMA for their Medicare products.

         (bullet) DHS  acknowledges  that the  Agreement  between  the  parties
                  creates a singular relationship which has been engendered by a
                  reliance  of  HCCMA on the good  faith of DHS to  respect  the
                  integrity of HCCMA, its parents,  subsidiaries and affiliates,

<PAGE>

                  as to  operational  and  organizational  needs.  In  order  to
                  secure,  fortify and  maintain  the said  relationship  hereby
                  acknowledged,  DHS will (1) keep HCCMA  fully  apprised of DHS
                  corporate structure and ownership and give HCCMA timely notice
                  of any changes  thereto;  (2) not use this  Agreement  and the
                  terms  thereof in a way that causes an improper  advantage  to
                  the   benefit  of  DHS  and  harm  to  HCCMA,   its   parents,
                  subsidiaries or affiliates; and (3) keep strictly confidential
                  and not disclose the terms of the Agreement.  Failure to abide
                  by either  the  intent  of this  provision  or its terms  will
                  accord  the  right to HCCMA to  terminate  the  Agreement  for
                  cause.

         (bullet) Medicare Risk Service Agreement Language Changes

                  The following changes or additions are also to be made or
                  provided in the attached form Medicare Risk Service Agreement:

               1.  Article  I,  Item  D.,  does  not  contain  a  hold  harmless
                   provision. No change required.

               2.  Article II, Item A., the reference to " . . . paragraphs B, C
                   and D" will be changed to ". . . paragraphs B, C and E."

               3. Article II, Item B., the term "usually"  will be deleted.  We
                  will  discuss  the concept of " . . directly or through one or
                  more  IPAs,   group   practices  or  other   entities  with  a
                  contractual  agreement with DHS or its  affiliates" to develop
                  contract  language  to  correctly  reflect the manner in which
                  DHS's networks are structured.

               4. Article III, Item D.,  language will be added to reflect that
                  persons who fail to make  required  payments  (deductible  and
                  copayment  amounts  under a Member's  plan) will be terminated
                  upon the  request of DHS within  HCCMA and HCFA  disenrollment
                  policies  once  unpaid   copayments  or  deductibles  reach  a
                  specific dollar amount and efforts to collect are unsuccessful
                  over a stated  period of time.  Language will also be added to
                  provide  that DHS will use its best  efforts to  collect  such
                  payments at the time of service.

               5. Article  III,  Item  G.,  will  provide  that a  copy  of the
                  documents  governing the Medical  Advisory  Committee  will be
                  supplied to DHS.

               6. Article III, Item J. 2., refers solely to HCCMA by
                  implication.  No change necessary.

               7. Article  III,  Item J. 3., will be changed to provide  that a
                  party against whom  involuntary  bankruptcy  proceedings  have
                  been  commenced  may  obtain a  sufficient  bond or have  such
                  proceedings  dismissed  within  ten (10) days  before  such an
                  event would permit termination of the Agreement.

<PAGE>


               8. Article IV, Item Q.3.,  will be modified to properly  reflect
                  the  relationship  of the parties  with  respect to the use of
                  such contracted providers.

               9. Article IV, Item R., will be revised to provide that any site
                  additions, deletions or address changes in facilities or hours
                  of operation by DHS will be communicated to HCCMA, in writing,
                  60 days prior to becoming effective.

              10. Attachment H will be completely revised.

HEALTH SYSTEM
Managing Quality Healthcare                                          May 8, 1996

Ms. Shirley Dail
Chesapeake Health Plan
814 Light Street
Baltimore, Maryland  21230

Dear Shirley:

The purpose of this Letter of Intent is to describe the terms of the contracting
agreements to which we have agreed, each of which will be included in a Medicare
Risk Service Agreement between Doctors Health System (DHS) and Chesapeake Health
Plan (CHP).  The following terms will be incorporated  (and changes made) in the
Medicare Risk Service  Agreement by June 1, 1996.  Until the contract  revisions
are  finalized  and said  contract is signed,  no later than June 1, 1996,  this
Letter of Intent will serve as the written contract between CHP and DHS.

TERM:

June 1, 1996 to May 31, 1997. Contract will be a term of one year, automatically
renewable for one year  increments  unless 90 days advance notice of termination
is provided by either  party.  Early  termination  may only be for cause upon 90
days prior written  notice after an  opportunity  to cure.  Termination  without
cause  may  occur at any time  after the  initial  term with 120 days  notice by
either party.

FINANCIAL TERMS:

(bullet) Chesapeake  Health Plan (CHP) will pay a  capitation  rate to DHS on a
         per member per month basis based on the age,  sex and Medicare
         eligibility  of the subscribers  enrolled with a DHS primary care
         physician in Chesapeake's Advantage 65 Medicare HMO program.  The DHS
         capitation  schedule is defined in Attachment A. This schedule
         represents the amount of capitation DHS will receive after carve out
         dollars have been deducted.

(bullet) The  payment  rates  defined  in  Attachment  A have been  derived
         from a mutually  agreed  upon  formula  which  is based on  HCFA's
         AAPCC  payment methodology. In the event that AAPCC methodology is
         changed or discontinued by HCFA, CHP may propose alternative pricing to
         DHS during the term of this agreement.  In the event that DHS does not
         accept revised  payment rates or terms, it may be considered cause for
         early termination of this agreement.

<PAGE>

(bullet) The  capitation  rates to DHS will  increase,  as defined in Attachment
         A, when DHS  enrollment  reaches  thresholds of [OMITTED AND FILED
         SEPARATELY WITH THE COMMISSION]  members,  and again at [OMITTED AND
         FILED SEPARATELY WITH THE COMMISSION] members.

(bullet) DHS capitation rates in Attachment A reflect a deduction by CHP to pay
         for "carve-outs."  The  carved-out  dollars will cover all costs
         related to the following services and DHS will have no further
         responsibility.  Changes to carve-outs  costs may be made annually,  on
         the anniversary of the contract term,  and with the mutual  consent of
         both  parties.  The following is the list of carved out services:

       (bullet) [OMITTED AND FILED  SEPARATELY WITH THE COMMISSION]

       (bullet) [OMITTED AND FILED   SEPARATELY  WITH  THE  COMMISSION]

       (bullet) [OMITTED  AND  FILED SEPARATELY  WITH THE  COMMISSION]

       (bullet) [OMITTED AND FILED  SEPARATELY WITH THE  COMMISSION]

       (bullet) [OMITTED  AND  FILED  SEPARATELY  WITH THE COMMISSION]

       (bullet) [OMITTED AND FILED  SEPARATELY  WITH THE COMMISSION]

       (bullet) [OMITTED AND FILED SEPARATELY WITH THE COMMISSION]

(bullet) Capitation  Payment is paid on a monthly basis to DHS by the Plan based
         on covered  lives  assigned  to DHS PCPs.  DHS will  assume  full risk
         for all "non-carved  out"  services  and  will  purchase  sufficient
         specific  and aggregate  stoploss  insurance to adequately  reinsure
         DHS financial  risk. Capitation Payment is paid to DHS by the 15th of
         the month with an itemized enrollment for that month, sorted by PCP.

(bullet) To accommodate financial reserve  requirements,  DHS will provide CHP
         with reasonably  acceptable  collateral  to secure an amount of not
         less than 90 days of DHS  Capitation.  CHP agrees that a Standby Letter
         of Credit from a commercial bank shall be deemed reasonably  acceptable
         collateral for such purposes, or an alternative method will be mutually
         agreed upon for same.

OTHER TERMS:

(bullet) DHS will assume responsibility for adjudication of all claims for
         services for which DHS is liable, including institutional claims.

(bullet) DHS  agrees  to  provide  detailed  utilization  reports  to CHP  for
         all professional  and  institutional  services.  CHP agrees to provide
         DHS with detailed  utilization  reports on carved out services.
         Specifications  for utilization  reporting  will be  defined  and
         mutually  agreed to prior to finalizing  contract.  CHP will provide
         technical  specifications  for DHS reporting  requirements in advance
         of finalizing contract.  The cost of any subsequent  changes  or
         deletions  to  this  reporting  requirement  which

<PAGE>

         requires customization to DHS systems will be paid for by CHP.

(bullet) There will be a 90 day limit on retroactive  additions or deletions to
         DHS capitated enrollment.

(bullet) Since DHS is accepting  full risk for all medical  services,  DHS
         reserves the right to  pre-certify  and manage the  utilization  of
         these  services, provided  that DHS  policies  for same are  approved
         by CHP's  Utilization Management Department.  DHS certification,
         utilization management and case management  standards and processes
         will be defined and mutually  agreed to before contract is finalized.

(bullet) CHP's  Advantage 65 Medicare HMO product design and marketing plan will
         be defined and agreed upon before contract is finalized.
         Material/substantive changes to the product design,  including  level
         of benefits,  deductibles, co-pays,  etc., will be  communicated  to
         DHS in advance of marketing.  DHS will have the option to consider this
         as cause for termination, and as such may opt to terminate the
         Agreement as a result of such changes with 90 days written notice.

(bullet) DHS  agrees to  support  the  marketing  effort of CHP for their
         Medicare products.  CHP will also provide  advertising  and marketing
         resources and initiatives  to DHS as a premier  medical  group within
         the CHP network.  A Medicare  Marketing  Addendum  will  be  documented
         and  attached  to this contract  outlining  the CHP  Marketing  Plan
         and  resource  commitment  to achieve DHS enrollment targets.

(bullet) DHS  reserves  the right to  subcontract  with any  provider  which
         meets mutually  agreed upon  credentialing  criteria.  CHP  reserves
         the right to disallow a DHS  provider  to treat CHP  members if that
         provider  has been sanctioned by CHP, the State or HCFA.

(bullet) Plan will delegate  credentialing of primary care and specialist
         providers to DHS.  DHS will  provide all  necessary  documentation  of
         credentialing policies and procedures.  DHS will make  credentialing
         files accessible to CHP for audit purposes.

(bullet) When primary care  physician  (PCP) elects to  participate in DHS
         contract with CHP,  CHP agrees to  facilitate  the  transition  of that
         physician's participation  agreement  and member  panel,  if any,  to
         the DHS  contract within 90 days of PCP  notifying  CHP of intention to
         terminate  individual contract and transition to DHS contract; unless
         member is an inpatient in a hospital or subacute  facility or in the
         process of an episode of specialty care,  in  which  case  member  will
         not  transition  to DHS  panel  until discharged  from  the  facility
         or  until  episode  of  specialty  care is completed. It is noted that
         the member will at all times have the option to disenroll  from the
         PCPs panel if that  transition  to the new panel is not their
         preference.

All other terms will be addressed in the formal contract  between DHS and CHP as
they relate to members  services and HMO policy and  procedure  requirements  as
mutually agreed upon by both parties.

negligence or the misconduct of the LLC, its agents, servants or employees, or
of any other person entering upon or using the Demised Premises under the
express or implied invitation of the LLC, or resulting from the violation of
laws or regulations, or violation of the terms of this Agreement by any of the
foregoing.

the damaged, or replace the destroyed, Demised Premises as soon as reasonably
possible and to make provision for temporary or interim use of such assets or
facilities in lieu of damaged or destroyed Demised Premises as may be reasonably
required to permit the LLC to continue its Practice of Medicine with minimal
disruption. Doctors Health shall have one hundred eighty (180) days to make
replacements, repairs and restorations, using insurance proceeds and such other
monies as Doctors Health may elect to contribute. In the event the Demised
Premises cannot be repaired, restored or replaced within such time period, or in
the event Doctors Health determines in its sole judgment that such repair,
restoration or replacement is not cost effective, Doctors Health shall have the
right to elect to terminate the LLC's lease or use of such portion of the
Demised Premises and to provide, pursuant to the terms hereof, such other
facilities, assets, equipment or office space as is reasonably appropriate to
permit the LLC and its physicians to resume its practice of medicine.

         n. SUBORDINATION. The LLC agrees that this Agreement shall be and is
subordinate to the lien of any and all conditional sale agreements, financing
arrangements, mortgages, deeds of trust, and ground leases that may now or

made thereunder, and to the interests thereon and all renewals, consolidations,
modifications, replacements and extensions thereof.

notice of the expiration of the Sublease pursuant to which any Office Space is
occupied by the LLC or the termination of the LLC's right to occupy any Office
Space under any other circumstances and will confer with the LLC concerning the
renegotiation, or renewal of such lease or other occupancy right and the removal
of the LLC to other premises.

where applicable and consistent with Section 4.c hereof, a reasonable allocative

physicians employed by the LLC, (2) salaries, wages, bonuses and all benefits of
professional and administrative staff employed by Doctors Health to provide
services directly to the LLC or its employee physicians in their practice of
medicine, but excluding employees whose services are provided directly to
Doctors Health (and only indirectly to the LLC) to enable Doctors Health to

<PAGE>

any Additional Primary Care Entities or other healthcare providers with which
Doctors Health contracts, (3) salaries, professional fees or other compensation,
including bonuses and all benefits, of all physicians and non-physician
professionals and all other persons employed, contracted or otherwise retained

be considered as capital, operating or other expenses of the LLC under
recognized and customary accounting principles and practices, including expenses

         Doctors Health shall be obligated to, and shall, pay the LLC's Business
Costs only out of and from the cash that Doctors Health ACTUALLY collects in
respect of and from those LLC's receivables with respect to which it is
appointed as the LLC's agent as provided in Section 3.b hereof, and with respect
to those receivables assigned, transferred and conveyed to Doctors Health
pursuant to such provision, and with respect to any other amounts which Doctors
Health collects or receives on behalf of the LLC (collectively, the "Collected
LLC Cash"). If, in Doctors Health's sole discretion, the Collected LLC Cash is
or will be insufficient to permit Doctors Health to pay all of the LLC's
Business Costs in the ordinary course of business as such Business Costs accrue,
Doctors Health shall give preference in payment to, and shall pay first, those
of the LLC's Business Costs NOT attributable to the salaries or benefits of
physicians employed by the LLC who are also Members of the LLC ("Member
Physicians") ("Non-Member Business Costs") and only after all such Non-Member
Business Costs are satisfied (or reasonable provision therefor in the sole
discretion of Doctors Health has been made) shall Doctors Health pay to the LLC
the funds to enable the Member Physicians to be paid any salary or benefits to
which they may be entitled pursuant to their Professional Service Employment
Agreements with the LLC. To the extent Doctors Health does not have sufficient
Collected

                                       8

<PAGE>

LLC Cash to pay to or for the benefit of the Member Physicians the aggregate of
all salary and benefits due to them (each such deficiency a "Member Physician
Salary Cost Deficiency") with respect to any month, (a) DHS shall pay to the
Member Physicians such amounts of the salary and benefits due to them in any
such month determined by multiplying the amount of Collected LLC Cash, if any,
Doctors Health deems available for such payments by a fraction, the numerator of
which is the amount of salary and benefits due in such month to such Member
Physician and the denominator of which is the aggregate of all salary and
benefits due in such month to all Member Physicians, and (b) Doctors Health
shall not be entitled to, and shall not receive, any Management Fee with respect
to such month. In addition, the amount of any Member Physician Salary Cost
Deficiency for such month shall, when added to all or any portion of any Member
Physician Salary Cost Deficiencies from prior months with respect to which
payment has not been made by Doctors Health, be deemed for purposes of the
calculation of the Management Fee pursuant to SECTION 4 hereof to be a "Business
Cost" with respect to each succeeding month through and including the month in
which such Member Physician Salary Deficiency has been paid in full, and Doctors
Health shall not be entitled to a Management Fee in any month during which there
are any Member Physician Salary Cost Deficiencies outstanding. In each month in
which there are no Member Physician Salary Cost Deficiencies outstanding, and in
each month where there exists sufficient LLC Collected Cash to pay all the LLC's
Business Costs and all outstanding Member Physician Salary Cost Deficiencies,
Doctors Health may pay to itself, from the LLC Accounts and after payment of all
of the LLC's Business Costs and outstanding Member Physician Salary Cost
Deficiencies, the Compensation to which it is otherwise entitled according to
the terms of SECTION 4 hereof.

                  Notwithstanding the foregoing, the LLC's Business Costs shall
NOT include, and Doctors Health shall have no obligation either to pay from the
LLC Collected Cash or otherwise, any costs, expenses or other charges incurred
by the LLC or presented to Doctors Health as a result of: (a) any action taken
by the LLC with respect to the employment terms and conditions, including
termination of employment, of any of its employee physicians to which Doctors
Health has not consented in writing; (b) any breach or deficiency in performance
by the LLC or any of its employee physicians of or under any contract to which
the LLC is a party or which was negotiated by Doctors Health on behalf of the
LLC; (c) violation of or failure to comply with any statute, law, regulation,
ordinance, interpretation, decision or other similar requirement of any federal,
state, or local political jurisdiction, or of any agency, commission, board or
other similar entity of any of the foregoing jurisdictions or any professional
organization with jurisdiction or authority over the ability of the LLC or any
of its employee physicians to engage in the practice of medicine; (d) any
willful or negligent act or omission of the LLC or any of its employee
physicians that results or may result in an award of damages against the LLC or
such employee physician whether in tort, contract or otherwise; or (e) any act
or omission on the

                                       9

<PAGE>

part of the LLC or any of its employee physicians constituting fraud, willful
misrepresentation or other similar conduct.

                  xiii. pay in a timely manner any Managed Care Incentive
Payment to which the LLC is entitled pursuant to the provisions of SECTION 5
hereof with respect to any MCIP Year to permit the LLC to reward and provide
appropriate incentives to its physician employees, all pursuant to the terms of
SECTION 5 hereof; and


                  xiv. perform all other acts reasonably necessary or desirable
in the operation and maintenance of the LLC in accordance with the terms and
conditions of this Agreement, except that Doctors Health shall not provide
medical or related professional services or engage in the Practice of Medicine.

         b. BILLING AND COLLECTION. The LLC hereby assigns, transfers and
conveys to Doctors Health all of its currently existing and future accounts
receivable with respect to all medical services previously provided or in the
future to be provided by the LLC (but not including any Medicare or Medicaid
payments currently owing, or which in the future become owing, to the LLC)
(collectively, the "Non-Medicare Receivables"). Doctors Health shall be entitled
to take any such action with respect to the Non-Medicare Receivables as it deems
appropriate in the exercise of its sole discretion. The LLC shall execute such
other documents and agreements as may be necessary to more fully and effectively
transfer the Non-Medicare Receivables to Doctors Health.

                  Doctors Health shall serve as billing and collection agent for
the LLC with respect to any Medicare and/or Medicaid payments currently owing,
or which in the future become owing, to the LLC (the "Medicare Receivables") and
shall bill for and endeavor to collect all such Medicare Receivables owed to the
LLC (reserving the right to send, with simultaneous notice to the LLC, selected
past-due accounts to a collection agency) and issue receipts therefor, if
required. The LLC hereby appoints Doctors Health as its agent and
attorney-in-fact for the collection of the Medicare Receivables. The LLC further
appoints Doctors Health as its attorney in fact and agent, to collect such
Medicare Receivables that Doctors Health deems uncollectible. Doctors Health
shall deposit all the Medicare Receivables in the bank accounts described in
SECTION 4.c. hereof.

                  Doctors Health will use its commercially reasonable efforts
to:

                  i. provide to the LLC, upon reasonable prior notice, such
reasonably detailed reports with respect to the LLC's accounts receivable,
billing and collection status, including charges, receipts, and insurance
classifications of patients as the LLC may from time to time reasonably request;

                                       10

<PAGE>

                  ii. should this Agreement be terminated, upon request
therefor, provide the LLC with a complete listing and print out of all active
patient accounts, all Medicare and third party insurer active billing records,
all demographic and charge data, and a final report detailing all data and
information pertinent to the LLC's accounts, in accordance with the normal
reporting capability of the billing system or contractor, if any, utilized for
the LLC's billing by Doctors Health; and

                  iii. use reasonable care in processing and storing the LLC's
data and records.

         c. BANK ACCOUNTS.

                  i. Doctors Health has opened the bank accounts described in
this SECTION 3.c.i for the purpose of depositing, disbursing and otherwise
administering the Collected LLC Cash. Doctors Health shall establish policies
and procedures reasonably satisfactory for managing and administering such
accounts, including designation and authorization of persons authorized to sign
checks. Doctors Health may, upon reasonable notice to the LLC, open in its name
such other bank accounts, including without limitation interest bearing accounts
and reserve accounts, as it may deem appropriate. Doctors Health may also
transfer Collected LLC Cash between any or all such accounts as it may establish
hereunder. Until disbursed by Doctors Health in payment of the LLC's Business
Costs or Doctors Health's Management Fee from such accounts, the Collected LLC
cash (other than such portion attributable to the Non-Medicare Receivables)
shall be and remain the property of the LLC. Doctors Health shall deposit,
disburse and administer the Collected LLC Cash as follows:

         A. Doctors Health, as the agent of the LLC, will from time to time
      maintain accounts with one or more financially secure banking
      institutions, into which it shall deposit promptly upon receipt all
      Collected LLC Cash which it receives as the agent of the LLC and on the
      LLC's behalf from Medicare and Medicaid and in respect of goods and
      services provided pursuant to the Medicare and Medicaid programs
      (collectively, the "LLC Medicare Account").

         B. Doctors Health will from time to time maintain accounts with one or
      more financially secure banking institutions, into which it shall deposit
      promptly upon receipt all of the Collected LLC Cash it receives from any
      sources other than those described in SECTION 3.c.i.A, above
      (collectively, the "LLC Cash Account") (the LLC Medicare Account, the LLC
      Cash Account and any other bank accounts established by Doctors Health
      hereunder are hereinafter collectively referred to as the "LLC Accounts").

                                       11

<PAGE>

                  ii. Doctors Health shall utilize the cash deposited in the LLC
Accounts for the purposes of paying the LLC Business Costs and Doctors Health's
Management Fee according to the following terms and conditions. Consistent with
the requirements of SECTION 3.a.xii hereof, Doctors Health shall give first
priority in the disbursement of funds from the LLC Accounts to the payment of
the Non-Member Business Costs. Doctors Health shall give second priority in the
disbursement of funds from the LLC Accounts to the payment of the salary and
benefits of the LLC's Member Physicians and to any Member Physician Salary Cost
Deficiencies. After all of the LLC's Business Costs (which, where appropriate,
shall include any Member Physician Salary Cost Deficiencies) have been paid,
Doctors Health may disburse and pay over to itself from the LLC Accounts Doctors
Health's Compensation calculated according to the provisions of SECTION 4.a
hereof. Subject to the requirements of applicable law, Manager may transfer
funds from the LLC Medicare Account to the LLC Cash Account in its discretion.

         d. CONSULTANTS. Doctors Health may engage on behalf of the LLC
consultants to provide specialized services outside the normal scope of
management services, including, but not limited to, legal representation, public
accounting and labor relations. All reasonable charges for outside consultants
will be LLC Business Costs.

         e. PERSONNEL. Doctors Health shall maintain supervisory control over
its personnel involved in providing to the LLC the assets, facilities and
services contemplated hereunder. Doctors Health will consult with the Quality
Committee if the LLC informs Doctors Health of any dissatisfaction with the
performance or staffing level of Doctors Health personnel without, however,
surrendering any of Doctors Health's discretion over the employment, discipline
and other conditions of employment related to Doctors Health employees.

         f. CONSENT. In any instance in which Doctors Health is required under
the terms of this Agreement to obtain the LLC's or the Management Committee's
consent or approval in connection with any proposed action, expenditure or
decision of any type, if Doctors Health's recommendations are not approved and
consent or approval is not received, Doctors Health shall have no responsibility
to the LLC with respect to the subject matter of the proposed action,
expenditure, or decision other than to act as directed by the Management
Committee or to maintain the status quo if no direction is received. Doctors
Health shall not be considered to be in violation of this Agreement or any part
thereof as a result of, or in connection with, any matter in which the LLC or
the Management Committee did not consent to or approve any action proposed by
Doctors Health; unless and to the extent Doctors Health shall fail to act as
directed by the LLC or the Management Committee or to maintain the status quo.

4.       COMPENSATION OF DOCTORS HEALTH; OBLIGATIONS OF THE LLC.

services provided by Doctors Health to the LLC pursuant to this Agreement, the
LLC hereby authorizes Doctors Health to pay to itself on behalf of the LLC from
the LLC Accounts, and Doctors Health shall be entitled to receive from the LLC,
Compensation (the "Compensation") calculated and paid monthly according to the
terms of this SECTION 4.a. The amount of Doctors Health's Compensation shall be
the amount determined by (i) subtracting the total amount of (A) all LLC

Physician Salary Cost Deficiencies outstanding, shall include the aggregate of
all such deficiency amounts) that Doctors Health pays or is obligated to pay
through disbursements from the LLC Accounts or provides for by transfers to
reasonable reserves established by Doctors Health, and (B) all bank fees,
charges and other deductions from the LLC Accounts made by the depository bank,
during a calendar month from (ii) the amount of (A) all Collected LLC Cash
deposited by Doctors Health in the LLC Accounts, and (B) all interest earned on

such calendar month. Doctors Health's Compensation shall be calculated and paid
on or before the tenth day of the month following the month for which payment is

LLC Cash remaining in the LLC Accounts after all LLC Business Costs (which, with
respect to any month in which there are Member Physician Salary Cost
Deficiencies outstanding, shall include the aggregate of all such deficiency
amounts) have been paid or provided for. Adjustments in the amount of the
Compensation for any month, if any, may be made after review of settled bank
statements by the independent certified public accountants retained by Doctors

                                       14

<PAGE>

Health's accountants). Doctors Health shall permit the LLC's accountants to

any disagreement or dispute between the LLC and Doctors Health relating to the
amount of the Compensation resulting from such review shall be subject to the
dispute resolution procedures of SECTIONS 7.b and 7.c hereof. Doctors Health
shall, if necessary, increase or decrease, as the case may be, the Compensation
next payable after its receipt of the results of such review (including dispute
resolution, if any) to reflect such results.

         b. GENERAL COVENANTS OF THE LLC. The LLC acknowledges that Doctors
Health has undertaken to provide significant assets, facilities and services to
the LLC pursuant to this Agreement in reliance upon the LLC's undertaking
diligently to engage, and to use its best efforts to cause its physician
employees diligently to engage, in the Practice of Medicine. The LLC therefore
covenants and agrees that it will diligently engage in the Practice of Medicine
in the Baltimore SMA and will use its best efforts to cause its physician
employees diligently to engage in, and to devote their full-time professional
efforts to, the Practice of Medicine in the Baltimore SMA. The LLC further
covenants and agrees that it will use its best efforts to meet or exceed the
financial, professional service and other standards established for the LLC in
the business plans and budgets prepared for the LLC by Doctors Health and
approved by the Management Committee and, in furtherance thereof, will engage,
and use its best efforts to cause its physician employees to engage, in the
Practice of Medicine in the most efficient and economical manner possible,
consistent with all applicable professional and ethical standards and a standard
of commercial reasonableness appropriate for application to Medical Practices in
the Baltimore SMA, including, specifically, those matters set forth in SECTION
4.d below.

         c. AUTHORIZATION OF PAYMENTS. The LLC acknowledges and agrees that its
intent in entering into this Agreement with Doctors Health is to secure from
Doctors Health all of the assets, facilities and non-physician services required
by the LLC to permit it to engage in the Practice of Medicine and, in
furtherance thereof, to enable and permit Doctors Health to pay, from the
Collected LLC Cash in the LLC Accounts, all of the reasonable costs and expenses
of providing such assets, facilities, and services, however and by whomever
incurred, by making disbursements of such Collected LLC Cash directly to
providers of assets, facilities or services or to the LLC or to Doctors Health
itself in reimbursement of costs or expenses incurred by either of them. The LLC
thus covenants and agrees that Doctors Health shall be entitled, and is hereby
authorized, to disburse from the Collected LLC Cash in the LLC Accounts such
funds as are required to pay all of the reasonable costs and expenses of
providing assets, facilities and services directly to the LLC pursuant to this
Agreement, it being the express understanding of the LLC that Doctors Health may
provide assets, facilities and services directly to Additional Primary Care
Entities and other medical service providers, and that such allocations of

                                       15

<PAGE>

costs incurred for the direct benefit of both the LLC and one or more Additional
Primary Care Entities or other medical service providers will be necessary.
Doctors Health shall, in its discretion, establish the basis for allocating each
category of direct cost and Doctors Health agrees to exercise such discretion in
a manner that results in the establishment of a basis for allocation of direct
costs that is reasonable and fair to the LLC and to each Additional Primary Care
Entity and any other provider entity to which such costs are allocated.
Disputes, if any, regarding such allocations shall be resolved first through the
Quality Committee and thereafter through the other procedures established in
SECTIONS 7.b and 7.c hereof. Doctors Health may, in its discretion, involve or

         (xvii) CREDENTIALLING. Cooperate with Doctors Health and the Quality

credentialling all of the LLC's physicians. Such credentialling criteria,

prior to the execution thereof and any amendments, or terminations, of such
agreements. It is understood and agreed that Doctors Health is not and shall not
become a party to any Professional Services Employment Agreements or other
employment agreements between the LLC and its physicians.

         (xix) PHYSICIAN OBLIGATIONS. The LLC shall be responsible for ensuring
that each of its physicians comply with the following requirements, all of which
have been incorporated by reference into the Professional Services Employment
Agreements with each physician. The LLC shall confer with Doctors Health
concerning the performance of its employee physicians of and under their
employment contracts generally and prior to taking any action to terminate any
such employment agreement. The LLC, at Doctors Health's request agrees to take
any reasonable action requested to enforce compliance, including, but not
limited to terminating such Physician's employment with the LLC and/or seeking
sanctions against such Physician:

                  (A) Each LLC physician shall abide by the terms and conditions
of the applicable provisions of this Agreement.

                  (B) Each LLC physician shall be bound to all components of all
agreements executed between Doctors Health and third party payors. Furthermore,
each physician shall abide by all operating rules and regulations of any managed
care plan for elements pertaining, but not limited to the maintenance of medical

non-discrimination in treatment of its members.

                  (C) Each LLC physician shall be free to exercise absolute
discretion in the conduct of any and all activities which may reasonably be
considered as constituting the Practice of Medicine. The professional
responsibility to patients for the delivery of health care services under this
Agreement shall at all times remain with each LLC physician. Doctors Health
shall not interfere with the professional judgment of any of the LLC's
physicians in the provision of professional health care services.

                  (D) Each LLC physician shall be required to participate in and
cooperate with the utilization review programs of third party payors and of
Doctors Health. Any determination under a utilization review program that
services provided or proposed to be provided are not medically necessary or not
otherwise appropriate shall in no case be construed as a substitute for the
professional judgment of each LLC physician; rather, such findings are intended
to be and shall be limited to the determination of reimbursement for services
only, it being understood that all decisions regarding the nature and extent of
services to be provided, as well as the choice of provider, are and will be made
exclusively by each LLC physician and his or her patient.

                                       19

<PAGE>

                  (E) Each LLC physician agrees that his or her practice
patterns will be profiled and will be reviewed by his or her peers, and that
participation in any of Doctors Health's preferred provider networks will be
dependent upon maintaining satisfactory profiles which are within Doctors
Health's and the Quality Committee's standards of acceptable medical practice.

                  (F) Each LLC physician shall refer patients to other
physicians only when it is deemed to be medically necessary and in the best
interest of such patients. When referrals are required, each LLC physician shall
use his or her best efforts to refer to other physicians who are participating
in any of the Manager's preferred provider networks then in effect, and to
utilize hospitals and other health care providers that are participating in any
such preferred provider network; provided, however, that no LLC physician shall
be required to refer a particular patient to any specific physician or to admit
such patient requiring hospitalization to any specific hospital if such LLC
Physician, in the good faith exercise of his or her professional judgment,
believes that the medical needs of such patient would be better served
elsewhere.

                  (G) Each LLC physician shall accept Managed Care Members as
new patients and treat current patients should they become Managed Care Members,
provided that no LLC physician shall be required to accept additional patients
if he is already working at full capacity, as determined by such physician and
the LLC jointly in the reasonable exercise of their discretion.

                  (H) Each LLC physician shall abide by decisions resulting from
utilization review programs of Doctors Health, the Quality Committee and/or
third party payors, subject to any applicable rights of reconsideration or
review. Each LLC physician shall pursue all appropriate opportunities for

services to be rendered to Managed Care Members.

                  (J) Each LLC physician shall allow each third party payor or
its designee to review and duplicate any data or other records maintained
regarding services provided under this Agreement as may be necessary to conduct
the utilization review program. Such review and duplication shall be allowed
upon reasonable notice during regular business hours and shall be subject to all
applicable laws, regulations and Doctors Health's policies concerning the
confidentiality of such data or records.

                  (K) Each LLC physician shall use his or her best efforts to
obtain precertification for those services designated by any utilization review

                                       20

<PAGE>

program(s) as requiring precertification, and shall use his or her best efforts
to notify the designated utilization review program of emergency or urgent
inpatient admissions within forty-eight (48) hours after admission.

                  (L) Each LLC physician shall cooperate as reasonably required
to verify that Managed Care Members are eligible for covered services.

                  (M) Each LLC physician shall prepare and maintain appropriate
records concerning health care services provided under this Agreement. All such
records shall be maintained in accordance with prudent record keeping
procedures, and as otherwise required by law.

                  (N) Notwithstanding anything provided herein to the contrary,
ownership of and access to all patient records shall be controlled by the
applicable state and federal law. All medical, financial, and personal
information about patients reviewed and collected in connection with this
Agreement shall be held in confidence and shall not be released, disclosed, or
published by the parties, their agents or employees without the written consent
of the patient, unless otherwise permitted by law. Each LLC physician shall be
responsible for supplying any consent necessary to the release of medical
records of patients for purposes of claims management, including specific
consent to the release of any records pertaining to any patient's alcohol or
drug addiction or treatment, or mental health commitment or treatment.

         (xx) FULL TIME. Except in cases of emergency, or as otherwise expressly
waived by Doctors Health, the LLC shall ensure that each LLC physician devotes
his or her full-time practice of medicine to the LLC's group practice, and shall
not provide professional services to persons other than Doctors Health and the
patients treated by LLC Physicians. For purposes of this Agreement, "full-time"
shall mean at a minimum the target number of Encounters per year per physician
agreed to by the LLC and each physician but shall also include any time devoted
to the charity care and education activities of Doctors Health and the Quality
Committee, and all time directly or indirectly pertaining to medical treatment
and care of patients, such as working on patient medical charts, making patient
rounds, and assisting with Doctors Health's or the LLC's administrative duties.
All patients treated by an LLC physician shall be deemed to be Doctors Health's
patients and Doctors Health shall be the owner of the medical records for all of
Doctors Health's patients.

         (xxi) NON-CONTRACT SPECIALISTS. When referrals to a specialist or other
physician is required, each LLC physician shall use his or her best efforts to
refer to physicians with whom Doctors Health has a provider contract in effect,
and, where applicable, to other physicians who are participating in any of the
Manager's preferred provider networks then in effect. In all other cases, each

                                       21

<PAGE>

LLC physician may select non-contract specialists to whom patients are referred,
based upon the such physician's best professional judgment of patient needs.

5.       MANAGED CARE INCENTIVE PAYMENT.

         a. CREATION OF MANAGED CARE INCENTIVE PAYMENT. The parties acknowledge
that both the Manager's Business Plan and the business plan developed by the
Manager for the LLC contemplate that the LLC and its physician employees will
shift the emphasis of their Practice of Medicine from a traditional
fee-for-service model to a managed care model, and that the Manager must
successfully manage the migration of the LLC's practice to a capitated model if
it is to meet its business goals and objectives. To provide an incentive for the
LLC and the physician employees of the LLC to engage in a managed care
environment in the most efficient and profitable manner possible, beginning with
the calendar year 1995, the Manager shall pay to the LLC, an amount, if any,
calculated as described herein (the "Managed Care Incentive Payment" or "MCIP")
with respect to each calendar year, or portion thereof, that occurs during the
term of this Agreement (each an "MCIP Year"). The Manager and the LLC shall
consult with each other as to the amount of the MCIP for each MCIP Year, subject
to the limitations established in Section 5.b hereof, and the Manager will
negotiate in good faith with the LLC in order to assure that all physician
employees are adequately compensated in light of the market in existence from
time to time.

         b. CALCULATION OF MANAGED CARE INCENTIVE PAYMENT. The Manager and the
LLC shall by December 15th of each year agree upon an MCIP payment to be made
out of the Manager's income before provision for income taxes or bonus (as
reflected on the Manager's financial statements) for the following year. There
shall be no MCIP payment in any year in which the Manager does not have income
before provision for income taxes or bonus reflected on its financial
statements. The Manager and the LLC shall agree upon an MCIP payment for each
year that is fair to the Manager and the LLC. If the Manager and the LLC are
unable to agree upon an MCIP, then the MCIP, if any, with respect to such MCIP
Year shall be equal to the lesser of either (i) twenty-five percent (25%) of the
amount of the excess, if any, of (A) those operating revenues of the Manager for
the MCIP Year that are properly attributable to the provision of medical care to
patients of the LLC, over (B) expenses of the Manager and the LLC for the MCIP
Year that are properly attributable or otherwise allocable to the LLC for the
MCIP year, or (ii) twenty-five percent (25%) of the Aggregate Base Salaries of
all primary care physicians employed by the LLC during such MCIP year. The
Manager shall have no obligation to negotiate for an MCIP in excess of either of
such amounts. The Manager shall have the right in its discretion to make
appropriate year to year and period adjustments to accurately reflect income and
expenses, and to allocate expenses among the LLC and any other Additional
Primary Care Entities, independent practice association or other person or
entity for which it serves as manager, and to set off against the amount of any
MCIP payment all or any portion of the amount of its costs and expenses
resulting from a breach by any

                                       23

<PAGE>

Physician or any Physician's PC of any representation, warranty or covenant made
by such Physician or PC in the Practice Participation Agreement."

         c. PAYMENT OF MANAGED CARE INCENTIVE PAYMENT. The Manager shall pay the
MCIP, if any, with respect to each MCIP Year to the LLC on or before February 15
of the calendar year following each such MCIP Year, beginning on February 15,
1996. If, pursuant to SECTION 4.a hereof, an adjustment is made in a succeeding
calendar year with respect to any Management Fee paid to the Manager in a prior
MCIP Year, no adjustment shall be made in the MCIP for the MCIP Year in which
the Management Fee which was subsequently adjusted was actually paid and such
adjustments shall be given effect in the MCIP for the MCIP Year in which they
were actually made.

6.       TERM AND TERMINATION.

         a. TERM. This agreement shall commence as of the date first above
written, and shall continue in force until December 31, 2025, unless sooner
modified or terminated as provided herein. This Agreement shall automatically be
renewed thereafter for additional terms (each an "Additional Term") for ten
years each in the sole discretion of Doctors Health so long as there is no event
of default with respect to Doctors Health performance of its duties hereunder as
set forth in SECTION 6.b of this Agreement.

         b. TERMINATION. This Agreement may be terminated by the non-defaulting
party upon the occurrence of any of the following events of default:

                  i. The commencement of any voluntary or involuntary case under
the Federal bankruptcy laws or any state insolvency or similar laws seeking the
liquidation or reorganization either party hereto, or the appointment of a
receiver, liquidator, assignee, custodian, trustee or similar official for
either party or the property of either party or the making by either party of an
assignment for the benefit of its creditors (except that in the case of any
involuntary action against either party, such party shall have sixty (60) days
to have such case dismissed), or the failure by either party generally to pay
its debts as they mature.

                  ii. Either party hereto is indicted upon a charge of
committing any felony or committing a misdemeanor which involves allegations of
fraud, embezzlement, conversion or other similar act or admits engaging in, or
is found in a duly convened arbitral proceeding or a court of competent
jurisdiction to have engaged in, illegal or other wrongful conduct substantially
detrimental to the business or reputation of the other party.

                  iii. The continued refusal by, or manifest inability of,
either party to perform any of the material duties, or to discharge any of the
material

                                       24

<PAGE>

obligations, of such party pursuant to this Agreement in a professional and
reasonably competent manner (consistent with applicable professional or business
standards) for a period of at least ninety (90) days after receipt of written
notice from the other party to such party providing reasonable detail as to the
specific material duties or obligations that are not being, or have not been,
performed or discharged by such party in a professional and reasonably competent
manner and providing a reasonable opportunity to such party to address such
failures or omissions and in good faith to attempt to cure or otherwise begin to
effect a remedy of such failures or omissions within such ninety (90) day
period; PROVIDED, HOWEVER, that the LLC may not terminate this Agreement so long
as Doctors Health is in good faith attempting to address any such failure or
omission and it appears reasonably possible that such failure or omission may
(or will) be cured before irreparable material harm or other significant injury
occurs to the LLC and, provided further, that the LLC may not terminate this
Agreement if any lender to, or holder of a senior security of, Doctors Health
arranges, or is arranging for, an assignment or transfer of such of Doctors
Health's duties hereunder as to which Doctors Health is in actual or potential
default to another management entity with experience in managing health care
providers that is reasonably acceptable to the LLC.

         c. EFFECT OF TERMINATION.

                  i. Upon the occurrence of an event of default by the LLC,
Doctors Health shall have the right without further notice to reenter and take
possession of the Demised Premises, or any part thereof, and to repossess the
same as Doctors Health's former estate, and expel the LLC and those claiming
through or under the LLC, and remove the effects of either or both without being
deemed guilty of any manner of trespass and without prejudice to any remedies
for arrears of fees due or preceding breaches of this Agreement.

                  ii. Upon the occurrence of an event of default by Doctors
Health, the LLC shall have the right to continue in full possession and use of
all of the assets, facilities and goods provided to it by Doctors Health,
including without limitation the Office Space and the Equipment, and to purchase
from Doctors Health for their appraised fair market value all of the assets of
Doctors Health constituting the Demised Premises and any other of Doctors
Health's assets which the LLC, in its sole discretion, deems necessary or
desirable to permit the LLC to continue its Practice of Medicine without
interruption, it being the intent of the parties to permit the LLC in such event
to continue its Practice of Medicine with as little disruption as possible. The
LLC shall be entitled to set off against the purchase price it pays for Doctors
Health's assets the amount of any damages incurred by the LLC as a result of
Doctors Health's breach of this Agreement.

7.       MODIFICATIONS; QUALITY COMMITTEE; ARBITRATION.

         a. MODIFICATION FOR PROSPECTIVE LEGAL EVENTS. If, in the good faith
opinion of either party, as supported by the written opinion of counsel to such
party, any Federal or state laws or regulations now existing or hereafter
promulgated or enacted, including specifically without limitation Medicare, are
interpreted by judicial decision, a regulatory agency or legal counsel in any
manner as to indicate that the structure of this Agreement, or any portion
thereof, may be in violation of such laws or regulations, such party may require
the parties hereto to use their respective best efforts to amend this Agreement,
or such portions hereof, to the extent necessary to avoid further violation. To
the maximum extent possible, any such amendment shall preserve the underlying
economic and financial risks, rewards and other arrangements set forth herein. A
party requesting such an amendment shall give written notice thereof to the
other party which shall set out in sufficient detail the basis for the amendment
request and specifically identify the specific provisions of this Agreement for
which renegotiation is sought. Within thirty (30) days of its receipt of the
requesting party's notice, the other party shall give notice to the requesting
party of any additional provisions of this Agreement as to which the other party
requests renegotiation and the reasons therefor. No provisions of this Agreement
other than those specifically designated by the parties for renegotiation shall
be affected by the renegotiations. Should the parties be unable to agree upon
mutually acceptable revisions to this Agreement within ninety (90) days after
receipt by the other party of the initial request for renegotiation, then the
matters that remain unresolved through renegotiation pursuant to this SECTION
7.a shall be submitted to binding arbitration pursuant to the provisions of
SECTION 7.c hereof. Each of the foregoing time periods shall be shortened if and
to the extent necessary to avoid a violation of applicable law in a timely
manner.

         b. QUALITY COMMITTEE. Doctors Health and the LLC hereby create the
Quality Committee referred to in this SECTION 7.b for the purpose of 
(i) developing cooperative developmental, management and administrative policies
to guide each of the LLC and Doctors Health in fulfilling its obligations
hereunder, (ii) providing to Doctors Health and the LLC a forum in which policy
and implementation matters affecting the LLC and its physicians may be discussed
on a regular basis, and (iii) establishing an expedited process through which
any disagreement or dispute between the parties to this Agreement relating to or
concerning (A) the quality, adequacy or appropriateness of the assets,
facilities or services provided by Doctors Health to the LLC, (B) the quality
and timeliness of the services provided by the LLC and its physicians to
patients pursuant to this Agreement, (C) the appropriateness of any expense
which Doctors Health treats as a Business Cost of the LLC, may be submitted for
review and resolution prior to any informal or formal adjudication. The Quality
Committee shall consist of six members, three appointed by the LLC and three

                                       26

<PAGE>

appointed by Doctors Health. Of the three members appointed by Doctors Health,
one shall be the Chief Executive Officer of DHS and one shall be the Executive
Vice President and Director of Medical Services of DHS. Of the three members
appointed by the LLC, one shall be the President of the LLC or his designee.
Either party may change the designation of any of its Quality Committee members
who is not serving EX-OFFICIO by written notice delivered to the other party
pursuant to the provisions of SECTION 10.p of this Agreement.

                  Doctors Health and the LLC agree to cause the Quality
Committee to meet regularly, but not less often than monthly. Where possible,
such meetings shall be scheduled to coincide with the dates of the regularly
scheduled meetings of DHS' Board of Directors. The Quality Committee shall adopt
such rules and regulations regarding the conduct of its business as it deems
appropriate.

                  If the LLC believes that any asset, facility or service
provided by Doctors Health to the LLC pursuant to this Agreement, including any
item of Equipment, any aspect of the Office Space, any goods, materials or
supplies or any administrative or other service, including any aspect of any
budget, business plan, policy or procedure, or any of the professional or
non-professional personnel provided to the LLC, is inadequate, inappropriate or
otherwise insufficient, then the LLC shall give written notice thereof to
Doctors Health, setting out in sufficient detail the basis for the LLC's
position. If Doctors Health believes that the quality or timeliness of the care
provided to any patient does not meet the standards established herein and in
each physician's Professional Services Employment Agreement, or that the LLC is
not cooperating in such reasonable efforts of Doctors Health to create a fully
integrated efficient health care delivery system as herein contemplated, then
Doctors Health shall give written notice thereof to the LLC which shall set
forth in sufficient detail the basis for Doctors Health's position. The Quality
Committee shall, within ten (10) days of the date of any such notice, convene a
special meeting and shall, in good faith endeavor to resolve the issues raised
in such notice by agreeing upon a unanimous recommendation with respect to such
issues, which shall be reported back to Doctors Health and the LLC. If within
thirty (30) days of the date of such notice there has been no joint
recommendation, or both parties have not accepted in writing a joint
recommendation of the Quality Committee as a basis for resolving all such
issues, the unresolved issues may be referred by either party to arbitration
pursuant to the provisions of SECTION 7.c hereof. Any joint recommendation of
the Quality Committee members which is accepted by both the LLC and Doctors
Health shall be promptly implemented.

         c. ARBITRATION. Any dispute between the parties of this Agreement
arising under or with respect to this Agreement, or any matters referred to
arbitration pursuant to the terms of SECTIONS 7.a OR 7.b hereof, shall be
submitted to binding arbitration according to the procedures set out on

                                       27

<PAGE>


SCHEDULE 13.1 of the Practice Participation Agreement of even date herewith,

SCHEDULE 13.1 being hereby incorporated into and as a part of this Agreement by
express reference. Each Party agrees to abide by the time periods and other
rules said forth in the said SCHEDULE 13.1. The resolution of any disputes
through such procedures, including without limitation through arbitral award,
shall be binding upon the Parties for all purposes and may be enforced in any
court of competent jurisdiction.

         a. DOCTORS HEALTH'S OBLIGATIONS.

                  i. Doctors Health shall, and shall use its best efforts to
cause its employees and Affiliates to, maintain all patient records and

such information to any third party without the LLC's prior written consent or

                  ii. Doctors Health may contract with other providers of
medical services to provide, and may provide, to such other providers of medical

civil or military authority, acts of public enemy, war, accidents, fires,
explosions, earthquakes, floods, failure of transportation, strikes or other
work interruptions by either party's service providers, employees or agents, or
any similar or dissimilar cause beyond the reasonable control of either party.

         g. WAIVER. A waiver by either party of a breach or failure to perform
any provision of this Agreement shall not constitute a waiver of any subsequent
breach of the same or a different provision hereof.

         h. SEVERABILITY. If any provision of this Agreement is found to be void
or unenforceable, then such provision shall be treated as severable, leaving
valid and enforceable the remainder of this Agreement.

         i. BINDING EFFECT AND ASSIGNMENT. This Agreement may not be assigned by
the LLC without the prior written consent of Doctors Health. BMG Limited
Partnership, as the initial Manager hereunder, may, for purposes of planning and
achieving internal management and staffing efficiencies, assign all of its
rights, title and interests in and to, and rights and obligations under, this
Agreement to any Subsidiary or Affiliate of BMG Limited Partnership, (as those
terms are defined in SECTION 9.2(e) AND (f) of the Practice Participation
Agreement), including, without limitation, DHS in its discretion and without the
prior written consent of the LLC and, upon such assignment by BMG Limited
Partnership, its assignee Subsidiary or Affiliate shall be and become Doctors
Health hereunder entitled to all of the rights and subject to all of the duties
and obligations of Doctors Health hereunder, without any other or further act by
any Person. Upon assignment by BMG Limited Partnership to a Subsidiary or
Affiliate pursuant to the preceding sentence, this Agreement shall not be
further assignable by any Manager without the prior written consent of the LLC.

         j. COUNTERPARTS. This Agreement may be executed in one or more
counterparts, all of which together shall constitute one Agreement.

         k. TAX LIABILITIES. The LLC shall have the sole responsibility for
paying any and all applicable Federal, state and local income taxes, gross
receipt taxes, FICA taxes, and all other withholding taxes, unemployment and
disability benefits, and workers' compensation obligations, and any and all
license and permit fees of whatever nature which may be applicable to it and for
filing all information and other tax returns and other returns or reports as may
be required of it. Doctors Health may act as payment agent for some or all of
these

                                       31

<PAGE>

taxes, without assuming responsibility for such payment. The LLC shall indemnify
and hold Doctors Health harmless against any and all claims against the LLC, any
physician employed by the LLC or Doctors Health, and related attorneys' fees,
for the failure to pay or file any of the foregoing payments, withholding,
contributions, taxes, fees, and documents, reports and returns, including but
not limited to, Federal, state, and local taxes, FICA taxes, gross receipt
taxes, unemployment and disability benefits, and workers' compensation
obligations, and any and all license and permit fees.

         l. INDEPENDENT RELATIONSHIP. The LLC and Doctors Health intend to act
and perform as independent contractors. Only the LLC shall practice medicine and
shall do so utilizing licensed physicians with no employment relationship to the
Manager. Notwithstanding the authority granted to Doctors Health herein, Doctors
Health and the LLC agree that the LLC shall retain the authority to direct the
medical, professional, and ethical aspects of its medical practice. Each party
shall be solely responsible for and shall comply with all state and federal laws
pertaining to employment taxes, income withholding, unemployment compensation
contributions and other employment related statutes applicable to that party. As
more specifically set forth herein, Doctors Health shall provide the LLC with
offices and facilities, equipment, supplies, support personnel, and management
and financial advisory services. As more specifically set forth in, and subject
to the provisions of, this Agreement and the LLC Operating Agreement, the LLC
shall be responsible for the recruitment and hiring of physicians and all issues
related to medical practice patterns and documentation thereof. Doctors Health
shall neither exercise control over nor interfere with the physician-patient
relationship, which shall be maintained strictly between the physicians of the
LLC and their patients. Matters involving the internal agreements and finances
of the LLC, including the distribution of professional fee income or
distributions of Managed Care Incentive Payments, if any, among the individual
Members and other physicians of the LLC, tax planning, and pension and
investment planning (and expenses relating solely to these internal business
matters) shall remain the sole responsibility of the LLC and/or the individual
physicians. The parties agree that the benefits to the LLC hereunder do not
require, are not payment for, and are not in any way contingent upon the
admission, referral or any other arrangement for the provision of any item or
service offered by Doctors Health or any of its Affiliates to any of the LLC's
patients in any facility or laboratory controlled, managed or operated by
Doctors Health.

         m. EXCHANGE OF INFORMATION. Each party shall cooperate in sharing with
and providing to the other party all information reasonably required or
desirable pursuant to the terms of this Agreement.

         n. FURTHER COOPERATION. The LLC shall cooperate and execute such
agreements and cause such of its physician employees as may be necessary to

                                       32

<PAGE>

become participating providers in such third-party reimbursement programs as
Doctors Health may from time to time direct. As used in this Agreement, the term
"third-party reimbursement program" shall include, but not be limited to, health
maintenance organizations, preferred provider organizations, private health
insurance companies, Blue Cross/Blue Shield, the Federal and State Medicare
and/or Medicaid programs, and any other managed care plan. The LLC shall also
cooperate with Doctors Health in promotional programs developed or selected by
Doctors Health.

         o. ENTIRE AGREEMENT. This Agreement and the other Practice Purchase
Closing Documents constitute the complete understanding of the parties and
supersede any and all other agreements, written or oral, between the parties
with respect to the subject matter hereof and thereon. No other agreement,
statement or promise not contained herein or therein shall be valid or binding.

MEDICAL GROUP, LLC, a Maryland limited liability company ("SUBTENANT").


                              EXPLANATORY STATEMENT

         A. By Lease Agreement dated_______________, 19___, a copy of which is

Where appropriate.]

         NOW, THEREFORE, FOR AND IN CONSIDERATION of the mutual entry into this
Sublease by the parties hereto and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged by each party
hereto, Tenant hereby subleases to Subtenant and Subtenant hereby subleases from

         1. Term; Extension and Expiration of Term. The term of this Sublease
(the "INITIAL TERM") shall be for a period of ______ (___) months [which period
shall be equal to the term of the Lease less one (1) day], beginning on
________, 19___ and expiring on ___________, 19____ (the "EXPIRATION DATE"). If

Subtenant provides such notice, this Sublease shall continue and extend until 
the expiration date of the renewal term less one (1) day (the "EXTENDED TERM") 
(both the Initial Term and the Extended Term shall be collectively referred to 
as the "TERM"). Tenant shall use reasonable efforts to notify Subtenant of the
Expiration Date of this Sublease at least thirty (30) days before the Expiration

         2. Rental. Subtenant shall pay to Tenant, without prior notice or

misconduct), pay taxes, insurance, and operating expenses, and any and all other
charges due and payable in connection with the occupancy and use of the
Premises, including, but not limited to, those payable to Landlord under the
Lease. Tenant and subtenant agree (A) that no actual payments are required to be

part of the Tenants Management Fee charged to Subtenant under that Certain
Professional Services Organization Agreement between Tenant and Subtenant dated
____________, 1996 (the "PSO Agreement"); (B) Tenants' payment of rent to the
landlord from time to time shall be deemed the payment of an "LLC Business Cost"

employees.

         3.  Obligations of Tenant and Subtenant Under the Lease.

                  3.1. In addition to any other obligations that are imposed

                  3.2. In addition to any other rights that are held by
Subtenant under the provisions of this Sublease, Subtenant shall have all of the
same rights hereunder against Tenant as Tenant has against Landlord under the
provisions of the Lease, and, except for the services to be provided by Landlord
to Tenant under the Lease, Tenant shall have all of the same obligations
hereunder to Subtenant as Landlord to Tenant under the Lease, all as if
provisions identical to such provisions were set forth at length in this
Sublease.

                  3.3. Without limiting the generality of the foregoing
provisions of this Section, 3.3.1. Subtenant covenants and agrees not to commit
any act that shall cause Tenant to be in breach of any term, covenant, or
condition under the

                                       36

<PAGE>

Lease or interfere with Tenant's performance of its obligations or duties under
the Lease;

                  3.3.2. in any instance in which Tenant has any right under the
provisions of the Lease to give or withhold its approval of any action,
omission, or other matter, or has any other discretionary right under the
provisions of the Lease, Tenant shall exercise such right in each instance in a
manner that is consistent with Subtenant's rights and Tenant's obligations
hereunder, and

                  3.3.3. in any such instance in which Tenant may exercise any
such right in two (2) or more ways, neither or none of which would be
inconsistent with Subtenant's rights and Tenant's obligations, Tenant shall
notify Subtenant thereof in writing, and shall exercise any right in accordance
with Subtenant's written instructions to Tenant; provided, however, that Tenant
must receive such instructions within such period, if any, during which Tenant
may be required by the provisions of the Lease to exercise or waive such right.

         4.  Amendment and Termination of Lease.

                  4.1. Tenant shall not amend, or consent to any amendment of,
the Lease in any respect that materially and adversely affects Subtenant's right
to use and enjoy the Premises on the terms and subject to the conditions that
are contained in this Sublease. No amendment of the Lease shall operate to alter
or impair Subtenant's rights hereunder.

                  4.2. If the Lease terminates for any reason this Sublease
shall thereupon automatically terminate simultaneously with such termination of
the Lease, and no party hereto shall have any right hereunder against any other
party hereto on account thereof; provided, however, that nothing in the
foregoing provisions of this sentence shall be deemed in any way to alter or
impair any liability that any party hereto may have to any other accruing before
such termination.

                  4.3. If the Lease terminates as a result of a default by
Tenant in performing its obligations thereunder, the parties hereto shall have
such rights and liabilities to each other hereunder on account of such default
as exist under applicable law.

                  4.4. On the expiration or earlier termination of this
Sublease, the rights and obligations of Landlord and Tenant shall be governed by
the Termination of Lease Agreement by and between Landlord and Tenant of even
date herewith.

communication or document to be provided hereunder to a party hereto shall be

         b. SUBLEASE OF OFFICE SPACE. Doctors Health, as sublessor, and the LLC,
as sublessee, shall, simultaneously with the execution of this Agreement (or as
soon after Closing as is reasonably practicable), enter into a Sublease in form

"SUBLEASE") for and in respect of each location where the LLC intends to
establish an office from which to engage in the Practice of Medicine as of the

the Equipment, as repaired, replaced or maintained, shall be sometimes
referred to collectively as the "DEMISED PREMISES".)

         d. USE OF DEMISED PREMISES. The LLC acknowledges and agrees that the
Demised Premises meet and fulfill its commercially reasonable needs for office

request. Doctors Health shall also provide for the removal of hazardous medical
waste generated by the LLC at the Office Space, provided that the LLC shall
comply with applicable regulatory waste handling, disposal and packaging
standards.

         g. REASONABLE ACCESS. The LLC agrees to allow Doctors Health reasonable
access to the Demised Premises, where such entry will not unreasonably interfere
with the LLC's use or occupancy, or with the provision of medical care or the
rights of any patient, in order to provide any of the services or fulfill any of
the duties of Doctors Health set forth in this Agreement, and/or to take steps
Doctors Health deems necessary for the safety, improvement or preservation of
the Demised Premises.

time to time request that Doctors Health make reasonable changes, additions or
improvements to the Office Space in order to permit the LLC to engage more
efficiently in the Practice of medicine or to enhance its profitability and,
subject to the limitations upon its leasehold or fee interest, Doctors Health
will endeavor to comply with such of the LLC's requests as it deems commercially
reasonable, provided that such changes shall comply with the applicable local,
state or Federal laws or regulations. The LLC shall not cause or permit
materialmen's, mechanics or other liens to be filed against the Office Space or
the Units or the interest of Doctors Health or any mortgagee in contravention of

and property taxes imposed upon the Office Space or the Units for which it is

coverage  on the  Demised  Premises,  business  interruption  insurance, general
liability  insurance  and professional  liability  insurance on any incidents  
occurring in connection with the LLC's occupancy and use of the Demised 
Premises, all of which  policies  shall be in amounts deemed reasonable by

additional insured.

         k.INDEMNIFICATION. The LLC shall indemnify and hold Doctors Health, its
employees,  agents,  officers, and partners or stockholders, as the case may be,
harmless from and against any and all demands, claims, judgments, losses and 
damages,  and any related costs or expenses  (including  reasonable  attorneys'
fees) arising from any injury or damage to person or property  caused by
the  negligence or the  misconduct of the LLC, its agents, servants or 
employees,  or of any other person  entering upon or using the Demised  Premises
under the express or implied  invitation  of the LLC, or resulting from the  
violation of laws or  regulations,  or violation of the terms of this Agreement 
by any of the foregoing.

         L. ASSIGNMENT/PLEDGE/ENCUMBRANCE. The LLC may not, without Doctors
Health's prior written consent, assign, sell, pledge, mortgage, encumber or in
any manner transfer any interest in nor sublet the Demised Premises or any part
or item thereof, nor permit occupancy or use of the Demised Premises or 


                                       4

any item thereof by any other Person other than in the ordinary course of the 
LLC's business.

any portion of the Demised Premises is damaged or destroyed by fire or other
casualty, Doctors Health shall use commercially reasonable efforts to restore
the damaged, or replace the destroyed, Demised Premises as soon as reasonably
possible and to make provision for temporary or interim use of such assets or
facilities in lieu of damaged or destroyed Demised Premises as may be reasonably
required to permit the LLC to continue its Practice of Medicine with minimal
disruption. Doctors Health shall have one hundred eighty (180) days to make
replacements, repairs and restorations, using insurance proceeds and such other
monies as Doctors Health may elect to contribute. In the event the Demised
Premises cannot be repaired, restored or replaced within such time period, or in
the event Doctors Health determines in its sole judgment that such repair,
restoration or replacement is not cost effective, Doctors Health shall have the
right to elect to terminate the LLC's lease or use of such portion of the
Demised Premises and to provide, pursuant to the terms hereof, such other
facilities, assets, equipment or office space as is reasonably appropriate to
permit the LLC and its physicians to resume its practice of medicine.

         n.SUBORDINATION. The LLC agrees that this Agreement shall be and is  
subordinate  to the  lien  of any  and all conditional sale agreements,  
financing arrangements,  mortgages, deeds of trust, and ground leases that may

services directly to the LLC or its employee physicians in their practice of

<PAGE>




any Additional Primary Care Entities or other healthcare providers with which
Doctors Health contracts, (3) salaries, professional fees or other compensation,
including bonuses and all benefits, of all physicians and non-physician
professionals and all other persons employed, contracted or otherwise retained
by Doctors Health to provide professional health care services or other services

supplies, of the LLC; (e) dues and license fees and other professional expenses
for LLC employees and Manager employees providing services to the LLC; (f) water
and sewer, gas, electricity, telephone and other utility charges; (g) premiums

charges for other equipment, goods, services (including professional and
consulting services) and utilities supplied to or for the benefit of the LLC;
(j) all acquisition, lease and financing expenses and payments, including all
leasehold expenses relating to office space, for the benefit of or relating to
the LLC; (k) costs of billing and collection of the LLC's fees and charges,
including contractors; and (l) such other expenses and charges as would normally
be considered as capital, operating or other expenses of the LLC under
recognized and customary accounting principles and practices, including expenses
incurred by Doctors Health on behalf of the LLC.

         Doctors Health shall be obligated to, and shall, pay the LLC's Business
Costs only out of and from the cash that Doctors Health ACTUALLY collects in
respect of and from those LLC's receivables with respect to which it is
appointed as the LLC's agent as provided in Section 3.b hereof, and with respect
to those receivables assigned, transferred and conveyed to Doctors Health
pursuant to such provision, and with respect to any other amounts which Doctors
Health collects or receives on behalf of the LLC (collectively, the "Collected
LLC Cash"). If, in Doctors Health's sole discretion, the Collected LLC Cash is
or will be insufficient to permit Doctors Health to pay all of the LLC's
Business Costs in the ordinary course of business as such Business Costs accrue,
Doctors Health shall give preference in payment to, and shall pay first, those
of the LLC's Business Costs NOT attributable to the salaries or benefits of
physicians employed by the LLC who are also Members of the LLC ("Member
Physicians") ("Non-Member Business Costs") and only after all such Non-Member
Business Costs are satisfied (or reasonable provision therefor in the sole
discretion of Doctors Health has been made) shall Doctors Health pay to the LLC
the funds to enable the Member Physicians to be paid any salary or benefits to
which they may be entitled pursuant to their Professional Service Employment
Agreements with the LLC. To the extent Doctors Health does not have sufficient
Collected 



                                       8


<PAGE>






LLC Cash to pay to or for the benefit of the Member Physicians the
aggregate of all salary and benefits due to them (each such deficiency a "Member
Physician Salary Cost Deficiency") with respect to any month, (a) DHS shall pay
to the Member Physicians such amounts of the salary and benefits due to them in
any such month determined by multiplying the amount of Collected LLC Cash, if
any, Doctors Health deems available for such payments by a fraction, the
numerator of which is the amount of salary and benefits due in such month to
such Member Physician and the denominator of which is the aggregate of all
salary and benefits due in such month to all Member Physicians, and (b) Doctors
Health shall not be entitled to, and shall not receive, any Management Fee with
respect to such month. In addition, the amount of any Member Physician Salary
Cost Deficiency for such month shall, when added to all or any portion of any
Member Physician Salary Cost Deficiencies from prior months with respect to
which payment has not been made by Doctors Health, be deemed for purposes of the
calculation of the Management Fee pursuant to SECTION 4 hereof to be a "Business
Cost" with respect to each succeeding month through and including the month in
which such Member Physician Salary Deficiency has been paid in full, and Doctors
Health shall not be entitled to a Management Fee in any month during which there
are any Member Physician Salary Cost Deficiencies outstanding. In each month in
which there are no Member Physician Salary Cost Deficiencies outstanding, and in
each month where there exists sufficient LLC Collected Cash to pay all the LLC's
Business Costs and all outstanding Member Physician Salary Cost Deficiencies,
Doctors Health may pay to itself, from the LLC Accounts and after payment of all
of the LLC's Business Costs and outstanding Member Physician Salary Cost
Deficiencies, the Compensation to which it is otherwise entitled according to
the terms of SECTION 4 hereof.

                Notwithstanding the foregoing,  the LLC's Business Costs shall 
NOT include, and Doctors Health shall have no
obligation either to pay from the LLC Collected Cash or otherwise, any costs,
expenses or other charges incurred by the LLC or presented to Doctors Health as
a result of: (a) any action taken by the LLC with respect to the employment
terms and conditions, including termination of employment, of any of its
employee physicians to which Doctors Health has not consented in writing; (b)
any breach or deficiency in performance by the LLC or any of its employee
physicians of or under any contract to which the LLC is a party or which was
negotiated by Doctors Health on behalf of the LLC; (c) violation of or failure
to comply with any statute, law, regulation, ordinance, interpretation, decision
or other similar requirement of any federal, state, or local political
jurisdiction, or of any agency, commission, board or other similar entity of any
of the foregoing jurisdictions or any professional organization with
jurisdiction or authority over the ability of the LLC or any of its employee
physicians to engage in the practice of medicine; (d) any willful or negligent
act or omission of the LLC or any of its employee physicians that results or may
result in an award of damages against the LLC or such employee physician whether
in tort, contract or otherwise; or (e) any act or omission on the 



                                       9




<PAGE>



part of the LLC or any of its employee physicians constituting fraud, willful
misrepresentation or other similar conduct.

                  xiii. pay in a timely manner any Managed Care Incentive

to the charity care and education activities of Doctors Health and the Quality
Committee, and all time directly or indirectly pertaining to medical treatment
and care of patients, such as working on patient medical charts, making patient

5.       MANAGED CARE INCENTIVE PAYMENT.

         a. CREATION OF MANAGED CARE INCENTIVE PAYMENT. The parties acknowledge
that both the Manager's Business Plan and the business plan developed by the
Manager for the LLC contemplate that the LLC and its physician employees will
shift the emphasis of their Practice of Medicine from a traditional
fee-for-service model to a managed care model, and that the Manager must
successfully manage the migration of the LLC's practice to a capitated model if
it is to meet its business goals and objectives. To provide an incentive for the
LLC and the physician employees of the LLC to engage in a managed care
environment in the most efficient and profitable manner possible, beginning with
the calendar year 1995, the Manager shall pay to the LLC, an amount, if any,
calculated as described herein (the "Managed Care Incentive Payment" or "MCIP")
with respect to each calendar year, or portion thereof, that occurs during the
term of this Agreement (each an "MCIP Year"). The Manager and the LLC shall
consult with each other as to the amount of the MCIP for each MCIP Year, subject
to the limitations established in Section 5.b hereof, and the Manager will
negotiate in good faith with the LLC in order to assure that all physician
employees are adequately compensated in light of the market in existence from
time to time.

         b. CALCULATION OF MANAGED CARE INCENTIVE PAYMENT. The Manager and the
LLC shall by December 15th of each year agree upon an MCIP payment to be made
out of the Manager's income before provision for income taxes or bonus (as
reflected on the Manager's financial statements) for the following year. There
shall be no MCIP payment in any year in which the Manager does not have income
before provision for income taxes or bonus reflected on its financial
statements. The Manager and the LLC shall agree upon an MCIP payment for each
year that is fair to the Manager and the LLC. If the Manager and the LLC are
unable to agree upon an MCIP, then the MCIP, if any, with respect to such MCIP
Year shall be equal to the lesser of either (i) twenty-five percent (25%) of the
amount of the excess, if any, of (A) those operating revenues of the Manager for
the MCIP Year that are properly attributable to the provision of medical care to
patients of the LLC, over (B) expenses of the Manager and the LLC for the MCIP
Year that are properly attributable or otherwise allocable to the LLC for the
MCIP year, or (ii) twenty-five percent (25%) of the Aggregate Base Salaries of
all primary care physicians employed by the LLC during such MCIP year. The
Manager shall have no obligation to negotiate for an MCIP in excess of either of
such amounts. The Manager shall have the right in its discretion to make
appropriate year to year and period adjustments to accurately reflect income and
expenses, and to allocate expenses among the LLC and any other Additional
Primary Care Entities, independent practice association or other person or
entity for which it serves as manager, and to set off against the amount of any
MCIP payment all or any portion of the amount of its costs and expenses
resulting from a breach by any 



                                       23


<PAGE>




Physician or any Physician's PC of any representation, warranty or covenant made
by such Physician or PC in the Practice Participation Agreement."

         c. PAYMENT OF MANAGED CARE INCENTIVE PAYMENT. The Manager shall pay the
MCIP, if any, with respect to each MCIP Year to the LLC on or before February 15
of the calendar year following each such MCIP Year, beginning on February 15,
1996. If, pursuant to SECTION 4.A hereof, an adjustment is made in a succeeding
calendar year with respect to any Management Fee paid to the Manager in a prior
MCIP Year, no adjustment shall be made in the MCIP for the MCIP Year in which
the Management Fee which was subsequently adjusted was actually paid and such
adjustments shall be given effect in the MCIP for the MCIP Year in which they
were actually made.

6.       TERM AND TERMINATION.

         a. TERM. This agreement shall commence as of the date first above
written, and shall continue in force until December 31, 2025, unless sooner
modified or terminated as provided herein. This Agreement shall automatically be
renewed thereafter for additional terms (each an "Additional Term") for ten
years each in the sole discretion of Doctors Health so long as there is no event
of default with respect to Doctors Health performance of its duties hereunder as
set forth in SECTION 6.B of this Agreement.

         b.  TERMINATION. This Agreement may be terminated by the non-defaulting
party  upon the  occurrence  of any of the following events of default:

                  i. The commencement of any voluntary or involuntary case under
the Federal bankruptcy laws or any state insolvency or similar laws seeking the
liquidation or reorganization either party hereto, or the appointment of a
receiver, liquidator, assignee, custodian, trustee or similar official for
either party or the property of either party or the making by either party of an
assignment for the benefit of its creditors (except that in the case of any
involuntary action against either party, such party shall have sixty (60) days
to have such case dismissed), or the failure by either party generally to pay
its debts as they mature.

                  ii. Either party hereto is indicted upon a charge of
committing any felony or committing a misdemeanor which involves allegations of
fraud, embezzlement, conversion or other similar act or admits engaging in, or
is found in a duly convened arbitral proceeding or a court of competent
jurisdiction to have engaged in, illegal or other wrongful conduct substantially
detrimental to the business or reputation of the other party.

                  iii. The continued refusal by, or manifest inability of,
either party to perform any of the material duties, or to discharge any of the
material 




                                       24



<PAGE>





obligations, of such party pursuant to this Agreement in a professional
and reasonably competent manner (consistent with applicable professional or
business standards) for a period of at least ninety (90) days after receipt of
written notice from the other party to such party providing reasonable detail as
to the specific material duties or obligations that are not being, or have not
been, performed or discharged by such party in a professional and reasonably
competent manner and providing a reasonable opportunity to such party to address
such failures or omissions and in good faith to attempt to cure or otherwise
begin to effect a remedy of such failures or omissions within such ninety (90)
day period; PROVIDED, HOWEVER, that the LLC may not terminate this Agreement so
long as Doctors Health is in good faith attempting to address any such failure
or omission and it appears reasonably possible that such failure or omission may
(or will) be cured before irreparable material harm or other significant injury
occurs to the LLC and, provided further, that the LLC may not terminate this
Agreement if any lender to, or holder of a senior security of, Doctors Health
arranges, or is arranging for, an assignment or transfer of such of Doctors
Health's duties hereunder as to which Doctors Health is in actual or potential
default to another management entity with experience in managing health care
providers that is reasonably acceptable to the LLC.

         c.       EFFECT OF TERMINATION.

                  i. Upon the occurrence of an event of default by the LLC,
Doctors Health shall have the right without further notice to reenter and take
possession of the Demised Premises, or any part thereof, and to repossess the
same as Doctors Health's former estate, and expel the LLC and those claiming
through or under the LLC, and remove the effects of either or both without being
deemed guilty of any manner of trespass and without prejudice to any remedies
for arrears of fees due or preceding breaches of this Agreement.

                  ii. Upon the occurrence of an event of default by Doctors
Health, the LLC shall have the right to continue in full possession and use of
all of the assets, facilities and goods provided to it by Doctors Health,
including without limitation the Office Space and the Equipment, and to purchase
from Doctors Health for their appraised fair market value all of the assets of
Doctors Health constituting the Demised Premises and any other of Doctors
Health's assets which the LLC, in its sole discretion, deems necessary or
desirable to permit the LLC to continue its Practice of Medicine without
interruption, it being the intent of the parties to permit the LLC in such event
to continue its Practice of Medicine with as little disruption as possible. The
LLC shall be entitled to set off against the purchase price it pays for Doctors
Health's assets the amount of any damages incurred by the LLC as a result of
Doctors Health's breach of this Agreement.

7.       MODIFICATIONS; QUALITY COMMITTEE; ARBITRATION.

         a. MODIFICATION FOR PROSPECTIVE LEGAL EVENTS. If, in the good faith
opinion of either party, as supported by the written opinion of counsel to such
party, any Federal or state laws or regulations now existing or hereafter
promulgated or enacted, including specifically without limitation Medicare, are
interpreted by judicial decision, a regulatory agency or legal counsel in any
manner as to indicate that the structure of this Agreement, or any portion
thereof, may be in violation of such laws or regulations, such party may require
the parties hereto to use their respective best efforts to amend this Agreement,
or such portions hereof, to the extent necessary to avoid further violation. To
the maximum extent possible, any such amendment shall preserve the underlying
economic and financial risks, rewards and other arrangements set forth herein. A
party requesting such an amendment shall give written notice thereof to the
other party which shall set out in sufficient detail the basis for the amendment
request and specifically identify the specific provisions of this Agreement for
which renegotiation is sought. Within thirty (30) days of its receipt of the
requesting party's notice, the other party shall give notice to the requesting
party of any additional provisions of this Agreement as to which the other party
requests renegotiation and the reasons therefor. No provisions of this Agreement
other than those specifically designated by the parties for renegotiation shall
be affected by the renegotiations. Should the parties be unable to agree upon
mutually acceptable revisions to this Agreement within ninety (90) days after
receipt by the other party of the initial request for renegotiation, then the
matters that remain unresolved through renegotiation pursuant to this SECTION
7.A shall be submitted to binding arbitration pursuant to the provisions of
SECTION 7.C hereof. Each of the foregoing time periods shall be shortened if and
to the extent necessary to avoid a violation of applicable law in a timely
manner.

         B. QUALITY COMMITTEE. Doctors Health and the LLC hereby create the
Quality Committee referred to in this SECTION 7.B for the purpose of (i)
developing cooperative developmental, management and administrative policies to
guide each of the LLC and Doctors Health in fulfilling its obligations
hereunder, (ii) providing to Doctors Health and the LLC a forum in which policy
and implementation matters affecting the LLC and its physicians may be discussed
on a regular basis, and (iii) establishing an expedited process through which
any disagreement or dispute between the parties to this Agreement relating to or
concerning (A) the quality, adequacy or appropriateness of the assets,
facilities or services provided by Doctors Health to the LLC, (B) the quality
and timeliness of the services provided by the LLC and its physicians to
patients pursuant to this Agreement, (C) the appropriateness of any expense
which Doctors Health treats as a Business Cost of the LLC, may be submitted for
review and resolution prior to any informal or formal adjudication. The Quality
Committee shall consist of six members, three appointed by the LLC and three




                                       26


<PAGE>



appointed by Doctors Health. Of the three members appointed by Doctors Health,
one shall be the Chief Executive Officer of DHS and one shall be the Executive
Vice President and Director of Medical Services if DHS. Of the three members
appointed by the LLC, one shall be the President of the LLC or his designee.
Either party may change the designation of any of its Quality Committee members
who is not serving EX-OFFICIO by written notice delivered to the other party
pursuant to the provisions of SECTION 10.P of this Agreement.

                  Doctors Health and the LLC agree to cause the Quality
Committee to meet regularly, but not less often than monthly. Where possible,
such meetings shall be scheduled to coincide with the dates of the regularly
scheduled meetings of DHS' Board of Directors. The Quality Committee shall adopt
such rules and regulations regarding the conduct of its business as it deems
appropriate.

                  If the LLC believes that any asset, facility or service
provided by Doctors Health to the LLC pursuant to this Agreement, including any
item of Equipment, any aspect of the Office Space, any goods, materials or
supplies or any administrative or other service, including any aspect of any
budget, business plan, policy or procedure, or any of the professional or
non-professional personnel provided to the LLC, is inadequate, inappropriate or
otherwise insufficient, then the LLC shall give written notice thereof to
Doctors Health, setting out in sufficient detail the basis for the LLC's
position. If Doctors Health believes that the quality or timeliness of the care
provided to any patient does not meet the standards established herein and in
each physician's Professional Services Employment Agreement, or that the LLC is
not cooperating in such reasonable efforts of Doctors Health to create a fully
integrated efficient health care delivery system as herein contemplated, then
Doctors Health shall give written notice thereof to the LLC which shall set
forth in sufficient detail the basis for Doctors Health's position. The Quality
Committee shall, within ten (10) days of the date of any such notice, convene a
special meeting and shall, in good faith endeavor to resolve the issues raised
in such notice by agreeing upon a unanimous recommendation with respect to such
issues, which shall be reported back to Doctors Health and the LLC. If within
thirty (30) days of the date of such notice there has been no joint
recommendation, or both parties have not accepted in writing a joint
recommendation of the Quality Committee as a basis for resolving all such
issues, the unresolved issues may be referred by either party to arbitration
pursuant to the provisions of SECTION 7.C hereof. Any joint recommendation of
the Quality Committee members which is accepted by both the LLC and Doctors
Health shall be promptly implemented.

         c. ARBITRATION. Any dispute between the parties of this Agreement
arising under or with respect to this Agreement, or any matters referred to
arbitration pursuant to the terms of SECTIONS 7.A OR 7.B hereof, shall be
submitted to binding arbitration according to the procedures set out on 



                                       27

between DOCTORS HEALTH SYSTEM, INC., a Maryland Corporation, ("TENANT")
CUMBERLAND VALLEY MEDICAL GROUP, LLC, a Maryland limited liability company
("SUBTENANT").


                              EXPLANATORY STATEMENT

         A. By Lease Agreement dated_______________, 19___, a copy of which is
attached hereto as Exhibit A (the "LEASE"), [Add appropriate recitals regarding
leases from Physicians and/or PCs, to the LP, to DHS] ___________, Maryland
known as ___________________ (the "PREMISES").

         B. Subtenant desires to sublease the Premises from Tenant and Tenant 
desires to sublease the Premises to Subtenant,  on the terms and subject to the
conditions which are hereinafter set forth.

         [C. Landlord  joins in the  execution of this Sublease to evidence its
consent to the within  Sublease,  as required by Section ______ of the Lease. 
Where appropriate.]

         NOW, THEREFORE, FOR AND IN CONSIDERATION of the mutual entry into this
Sublease by the parties hereto and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged by each party
hereto, Tenant hereby subleases to Subtenant and Subtenant hereby subleases from
Tenant all of the Premises in its "as is" physical condition (Subtenant having
heretofore examined and being familiar in all respects with the Premises), on
the terms and subject to the conditions which are hereinafter set forth:

         1. Term; Extension and Expiration of Term. The term of this Sublease
(the "INITIAL TERM") shall be for a period of ______ (___) months [WHICH PERIOD
SHALL BE EQUAL TO THE TERM OF THE LEASE LESS ONE (1) DAY], beginning on
________, 19___ and expiring on ___________, 19____ (the "EXPIRATION DATE"). If
the term of the Lease is renewed, Subtenant may extend the Initial Term for a
period coterminous with the extended period less one (1) day on the same terms
and conditions as set forth in this Sublease by providing Tenant with at least
_________ (___) days' notice in advance of the Expiration Date. If 




                                       35



<PAGE>



Subtenant provides such notice, this Sublease shall continue and extend until
the expiration date of the renewal term less one (1) day (the "EXTENDED TERM") 
(both the Initial Term and the Extended Term shall be collectively referred to
as the "TERM"). Tenant shall use reasonable efforts to notify Subtenant of the
Expiration Date of this Sublease at least thirty (30) days before the Expiration
Date.

         2. Rental. Subtenant shall pay to Tenant, without prior notice or
demand and without set-off or reduction, as rental for the Premises (the
"RENT"), the amount of ________ Dollars ($__________) per month during the
Term.. Rent shall be prorated on a daily basis for any partial calendar month
during the Term. This Sublease is on an absolute gross lease basis and Landlord
shall maintain the Premises (including repair or replacement of any part
thereof, unless such replacement is due to Subtenant's negligence or willful
misconduct), pay taxes, insurance, and operating expenses, and any and all other
charges due and payable in connection with the occupancy and use of the
Premises, including, but not limited to, those payable to Landlord under the
Lease. Tenant and subtenant agree (A) that no actual payments are required to be
made by Subtenant to Tenant of Rent hereunder, all such Rent due herewith being
part of the Tenants Management Fee charged to Subtenant under that Certain
Professional Services Organization Agreement between Tenant and Subtenant dated
___________, 199_ (the "PSO Agreement"); (B) Tenants' payment of rent to the
landlord from time to time shall be deemed the payment of an "LLC Business Cost"
under the PSO Agreement, and a "Direct Medical Facilities Cost" under the
Professional Services Employment Agreement for each of the Subtenant's physician
employees.

         3.  Obligations of Tenant and Subtenant Under the Lease.

                  3.1. In addition to any other obligations that are imposed
upon Subtenant under the provisions of this Sublease, Subtenant shall abide by
any restriction placed on Tenant pursuant to the terms of the Lease.

                  3.2. In addition to any other rights that are held by
Subtenant under the provisions of this Sublease, Subtenant shall have all of the
same rights hereunder against Tenant as Tenant has against Landlord under the
provisions of the Lease, and, except for the services to be provided by Landlord
to Tenant under the Lease, Tenant shall have all of the same obligations
hereunder to Subtenant as Landlord to Tenant under the Lease, all as if
provisions identical to such provisions were set forth at length in this
Sublease.

                  3.3. Without limiting the generality of the foregoing
provisions of this Section, 3.3.1. Subtenant covenants and agrees not to commit
any act that shall cause Tenant to be in breach of any term, covenant, or
condition under the 





                                       36


<PAGE>




Lease or interfere with Tenant's performance of its obligations or duties under 
the Lease;

                  3.3.2. in any instance in which Tenant has any right under the
provisions of the Lease to give or withhold its approval of any action,
omission, or other matter, or has any other discretionary right under the
provisions of the Lease, Tenant shall exercise such right in each instance in a
manner that is consistent with Subtenant's rights and Tenant's obligations
hereunder, and

                  3.3.3. in any such instance in which Tenant may exercise any
such right in two (2) or more ways, neither or none of which would be
inconsistent with Subtenant's rights and Tenant's obligations, Tenant shall
notify Subtenant thereof in writing, and shall exercise any right in accordance
with Subtenant's written instructions to Tenant; provided, however, that Tenant
must receive such instructions within such period, if any, during which Tenant
may be required by the provisions of the Lease to exercise or waive such right.

         4.  Amendment and Termination of Lease.

                  4.1. Tenant shall not amend, or consent to any amendment of,
the Lease in any respect that materially and adversely affects Subtenant's right
to use and enjoy the Premises on the terms and subject to the conditions that
are contained in this Sublease. No amendment of the Lease shall operate to alter
or impair Subtenant's rights hereunder.

                  4.2. If the Lease terminates for any reason this Sublease
shall thereupon automatically terminate simultaneously with such termination of
the Lease, and no party hereto shall have any right hereunder against any other
party hereto on account thereof; provided, however, that nothing in the
foregoing provisions of this sentence shall be deemed in any way to alter or
impair any liability that any party hereto may have to any other accruing before
such termination.

                  4.3. If the Lease terminates as a result of a default by
Tenant in performing its obligations thereunder, the parties hereto shall have
such rights and liabilities to each other hereunder on account of such default
as exist under applicable law.

                  4.4. On the expiration or earlier termination of this
Sublease, the rights and obligations of Landlord and Tenant shall be governed by
the Termination of Lease Agreement by and between Landlord and Tenant of even
date herewith.

         5. Notices. Any notice, demand, consent, approval, request, or other
communication or document to be provided hereunder to a party hereto shall be

Office  Space in a reasonably  tidy and clean  condition at the end of each day,
and such other  more  substantial  janitorial  services  the LLC may  reasonably
request.  The Manager  shall also provide for the removal of  hazardous  medical

rights of any patient, in order to provide any of the services or fulfill any of
the duties of the Manager set forth in this Agreement,  and/or to take steps the
Manager  deems  necessary for the safety,  improvement  or  preservation  of the
Demised Premises.

         h. Changes, Additions or Improvements to Office Space. The LLC may from
time to time  request  that the Manager make  reasonable  changes,  additions or

efficiently  in the  Practice of Medicine or to enhance its  profitability  and,
subject to the limitations upon its leasehold or fee interest,  the Manager will
endeavor  to comply  with such of the LLC's  requests  as it deems  commercially
reasonable,  provided that such changes shall comply with the applicable  local,
state or  Federal  laws or  regulations.  The LLC  shall  not  cause  or  permit
materialmen's,  mechanics or other liens to be filed against the Office Space or
the Units or the interest of the Manager or any  mortgagee in  contravention  of

liability  insurance  and  professional   liability   insurance on any incidents
occurring  in  connection  with  the  LLC' s  occupancy  and  use of the Demised

judgments,  losses and damages, and any related  costs  or  expenses  (including
reasonable   attorneys' fees)  arising  from  any  injury or damage to person or
property  caused by the  negligence  or the  misconduct  of the LLC, its agents,
servants  or  employees,  or  of  any  other  person  entering upon or using the
Demised  Premises  under  the  express  or  implied  invitation  of  the LLC, or
resulting from the violation of laws or regulations,  or violation of  the terms
of  this  Agreement  by  any  of the  foregoing  to the  extent  such  injury or
damage  is  not  covered  by  insurance  or does not  arise as a  result  of the
Manager's  breach  of its  obligations  to the LLC  under  this Agreement.

         l.   Assignment/Pledge/Encumbrance.   The  LLC  may  not,  without  the
Manager's prior written consent, assign, sell, pledge, mortgage,  encumber or in
any manner transfer any interest in nor sublet the Demised  Premises or any part
or item thereof, nor permit occupancy or use of the Demised Premises or any item
thereof  by any other  Person  other  than in the  ordinary  course of the LLC's
business.

any portion of the Demised  Premises  is damaged or  destroyed  by fire or other
casualty,  the Manager shall use commercially  reasonable efforts to restore the
damaged,  or replace  the  destroyed,  Demised  Premises  as soon as  reasonably
possible and to make  provision  for  temporary or interim use of such assets or
facilities in lieu of damaged or destroyed Demised Premises as may be reasonably
required to permit the LLC to continue  its  Practice of Medicine  with  minimal
disruption.  The  Manager  shall  have one  hundred  eighty  (180)  days to make
replacements,  repairs and restorations, using insurance proceeds and such other
monies as the Manager may elect to contribute. In the event the Demised Premises
cannot be  repaired,  restored or replaced  within such time  period,  or in the
event the Manager determines in its sole judgment that such repair,  restoration
or replacement is not cost effective,  the Manager shall have the right to elect
to terminate the LLC's lease or use of such portion of the

                                       4

Demised  Premises and to  provide,  pursuant  to the terms  hereof,  such  other

and  is  subordinate  to  the lien of any and all conditional  sale  agreements,
financing  arrangements,  mortgages,  deeds of trust, and ground leases that may
now  or  hereafter  be  placed  upon  the Demised  Premises,  and to any and all
advances to  be  made thereunder, and to the interests thereon and all renewals,
consolidations, modifications, replacements and extensions thereof.

         o. Sublease  Renewals.  The Manager will provide to the LLC  reasonable
notice of the  expiration of the Sublease  pursuant to which any Office Space is
occupied by the LLC or the  termination  of the LLC's right to occupy any Office
Space under any other  circumstances and will confer with the LLC concerning the
renegotiation, or renewal of such lease or other occupancy right and the removal
of the LLC to other premises.

<PAGE>

this  Agreement,  except  that  the Manager shall not provide medical or related
professional services or engage in the Practice of Medicine.

         b.       Billing and Collection.

                  (i) During the term of this Agreement, the LLC hereby assigns,
transfers  and conveys to the Manager all of the LLC's  currently  existing  and
future  accounts  receivable  with  respect to all medical  services  previously
provided  or in the  future to be  provided  by the LLC (but not  including  any
Medicare or Medicaid  payments  currently  owing,  or which in the future become
owing, to the LLC) (collectively,  the "Non-Medicare Receivables").  The Manager
shall  bill  for and  endeavor  to  collect  all such  Non-Medicare  Receivables
(reserving  the right to send,  with  simultaneous  notice to the LLC,  selected
past-due  accounts to a  collection  agency)  and issue  receipts  therefor,  if
required.  Furthermore,  subject to the Manager's  obligations under Section 3.c
hereof with respect to the establishment of the bank accounts described therein,
the  Manager  shall be  entitled  to take any such  action  consistent  with the
provisions of this Agreement with respect to the Non-Medicare  Receivables as it
deems  appropriate  in the  exercise of its  discretion  in order to fulfill its
obligations  to the LLC under this  Agreement.  The LLC shall execute such other
documents  and  agreements  as may be  necessary  to more fully and  effectively
transfer the Non-Medicare Receivables to the Manager. The Manager shall serve as
billing and  collection  agent for the LLC with respect to any  Medicare  and/or
Medicaid  payments  currently owing, or which in the future become owing, to the
LLC (the "Medicare  Receivables") and shall bill for and endeavor to collect all
such Medicare  Receivables  owed to the LLC (reserving  the right to send,  with
simultaneous  notice to the LLC,  selected  past-due  accounts  to a  collection
agency) and issue receipts  therefor,  if required.  The LLC hereby appoints the
Manager as its agent and  attorney-in-fact  for the  collection  of the Medicare
Receivables.  The Manager shall deposit all the Medicare  Receivables and all of
the other monies collected by it as the LLC's billing agent and attorney-in-fact
in the bank accounts described in Section 3.c hereof.


                  (ii)     As part of its billing  responsibility,  the  Manager
will use its commercially reasonable efforts to:

                           (A)      provide to the LLC, monthly, such reasonably
detailed reports  with  respect  to the  LLC's  accounts receivable, billing and
collection status, including charges,  receipts, and  insurance  classifications
of patients as the LLC may from time to time reasonably request;

                           (B)      should  this Agreement be  terminated,  upon
request  therefor,  provide the  LLC with a  complete  listing  and print out of
all  active  patient  accounts,  all  Medicare  and  third  party insurer active
billing  records,  all  demographic  and  charge  data,  and  a   final   report
detailing  all  data  and  information   pertinent  to  the  LLC's accounts,  in

                                       9

<PAGE>


accordance  with  the  normal  reporting  capability  of  the billing  system or
contractor,  if any,  utilized for the LLC's  billing by the Manager; and

                           (C) use reasonable care in processing and storing the
LLC's data and records.

                  (iii) The parties  recognize  that the Manager  cannot bill or
collect  for  services  provided by and through the LLC unless and to the extent
that the LLC Physicians perform in a timely manner certain administrative duties
related to  billing,  including  but not  limited to the  completion  of medical
records  and the  submission  of  billing  information  in the form  and  format
reasonably requested by the Manager.

                           (A)      The  LLC  warrants  that   it  will  require
that  each  LLC  Physician  will be  required, as  part of his or her Employment
Agreement,  to agree to grant to the LLC the right to  withhold   payment of any
amount due Physician  under his or her Employment  Agreement  during  any period
when such Physician has failed to comply with  commercially  reasonable  written
standards  communicated  to  the  Physicians  ("Standards")  for  timeliness and
diligence to be adopted by the LLC with respect to  each of the  following:  (i)
Completion of  appropriate  medical  records  for  patients  of  the  Physician;
(ii)  Maintaining  the office  hours agreed upon by Physician and the LLC; (iii)
Completion  of  all  information  reasonably requested by the LLC or its billing
agent in connection  with  billing and  collecting  for services  provided by or
ordered by the Physician;  or (iv)  Compliance  with the requirements of managed
care programs with respect to utilization review,  prior approval  or review, or
referral protocols.

                           (B)      The LLC agrees that it shall  adopt and  set
such  Standards  in  consultation  with  the  Manager.  The Manager has proposed
interim  Standards  set forth in Exhibit 3.b(iii)(B)  which shall be  applicable
during  the  Initial   Base  Salary  Period  until  the  Standards  described in
Section  3.b(iii)(A)  have been established  by  the  LLC.   The  LLC  expressly
grants  to the  Manager  the  right  to  require  enforcement by the LLC of each
of the covenants and rights to adjust or withhold  payments  to LLC  Physicians,
including  the right to  withhold  for  failure  to comply  with  the  Standards
contained  in  Section  6.4(c)  of the  Employment Agreement.  In the event that
the  LLC  fails  to  enforce  such  Standards  at the Manager's   request,   the
Manager's   obligations  to  advance  any  Physician Compensation Deficiency (as
defined  in  Section  3.m(iv)) shall  be suspended during the period of any such
non-compliance.

         c.       Bank Accounts.

                  i. The Manager has opened the bank accounts  described in this
Section  3.c.i  for  the  purpose  of   depositing,   disbursing  and  otherwise
administering  the Collected  LLC Cash (as defined in Section 3.m).  The Manager
shall establish policies and procedures reasonably satisfactory for managing and
administering such accounts,  including designation and authorization of persons
authorized to sign checks.  The

                                       10

<PAGE>

Manager  may, upon reasonable  notice to the LLC, open  in  the  Manager's  name
such  other  bank  accounts,  including   without  limitation  interest  bearing
accounts  and  reserve  accounts,  as it  may  deem appropriate. The Manager may
also transfer Collected LLC Cash between any or   all  such  accounts  as it may
establish  hereunder.  Until  disbursed  by  the Manager in payment of the LLC's
Business   Costs  or  the   Manager's   Compensation  from  such  accounts,  the
Collected LLC  Cash  (other than such portion  attributable  to the Non-Medicare
Receivables)  shall  be  and  remain  the  property  of  the  LLC.   The Manager
shall  deposit,  disburse  and  administer  the  Collected  LLC Cash as follows:

              A. The  Manager,  as the agent of the LLC,  will from time to time
              maintain  accounts  with one or more  financially  secure  banking
              institutions,  into which it shall  deposit  promptly upon receipt
              all  Collected  LLC Cash which it receives as the agent of the LLC
              and on the LLC's behalf from  Medicare and Medicaid and in respect
              of goods  and  services  provided  pursuant  to the  Medicare  and
              Medicaid programs (collectively, the "LLC Medicare Account").

              B. The Manager will from time to time  maintain  accounts with one
              or more  financially  secure banking  institutions,  into which it
              shall deposit  promptly upon receipt all of the Collected LLC Cash
              it receives from any sources other than those described in Section
              3.c.i.A  above  (collectively,  the "LLC Cash  Account")  (the LLC
              Medicare Account, the LLC Cash Account and any other bank accounts
              established by the Manager hereunder are hereinafter  collectively
              referred to as the "LLC Accounts").

                  ii. The Manager  shall  utilize the cash  deposited in the LLC
Accounts  for the purposes of paying the LLC  Business  Costs and the  Manager's
Compensation  according  to the terms and  conditions  set forth in Section 3.m.
Subject to the  requirements  of applicable  law, the Manager may transfer funds
from the LLC Medicare Account to the LLC Cash Account in its discretion.

         d.       Consultants.  Subject to the  approval of the LLC, the Manager
may  engage  on  behalf  of the LLC consultants to provide specialized  services
outside the normal scope of  management   services,  including,  but not limited
to,  legal  representation,  public  accounting   and   labor   relations.   All
reasonable  charges for outside consultants will be LLC Business Costs.

         e. Personnel.  The Manager shall maintain  supervisory control over its
personnel  involved in providing to the LLC the assets,  facilities and services
contemplated  hereunder.  The Manager will consult with the Quality Committee if
the LLC informs  the  Manager of any  dissatisfaction  with the  performance  or
staffing level of the Manager personnel  without,  however,  surrendering any of
the Manager's discretion over the employment, discipline and other conditions of
employment related to the Manager employees.

         f. Consent.  In any instance in which the Manager is required under the
terms of this  Agreement  to  obtain  the  LLC's or the  Management  Committee's
consent or approval in  connection  with any  proposed  action,  expenditure  or
decision of any type,  if the  Manager's  recommendations  are not  approved and
consent or approval is not received, the Manager shall have no responsibility to
the LLC with respect to the subject matter of the proposed action,  expenditure,
or  decision  other than to act as directed by the  Management  Committee  or to
maintain the status quo if no direction  is received.  The Manager  shall not be
considered to be in violation of this  Agreement or any part thereof as a result
of,  or in  connection  with,  any  matter  in which  the LLC or the  Management
Committee  did not  consent to or approve any action  proposed  by the  Manager;
unless and to the extent the Manager shall fail to act as directed by the LLC or
the Management Committee or to maintain the status quo.

         g.  Contracting.  The LLC hereby authorizes the Manager as its sole and
exclusive  agent to  negotiate  and enter into,  administer  and  terminate  all
contractual  arrangements  between the LLC and Persons to whom the LLC  provides
goods or services or from whom the LLC  receives  goods or services or with whom
the LLC contracts to provide medical professional or other services to the LLC's
patients or customers.  The LLC hereby constitutes the Manager as the LLC's sole
and  exclusive  agent and  attorney-in-fact  for the  purpose of  executing  the
authority  granted the Manager  pursuant to this Paragraph 3.g. The  contracting
authority  afforded the Manager  hereunder  includes,  without  limitation,  the
authority to contract with hospitals,  other physicians (including specialists),
hospices, nursing homes, pharmacies,  laboratories, providers of transportation,
home  health  care  providers,  nurses,  and  other  non-physician  health  care
providers,   medical   equipment   providers  and  other  providers  of  medical
professional  services  and other  health care  services,  patients,  customers,
insurance  companies,  health  maintenance  organizations and other managed care
entities, employers, administrators and other third-party payors of patient care
services or goods  provided by the LLC. The Manager shall secure the LLC's prior
consent to enter into any  contract  on behalf of the LLC for goods or  services
for which the LLC will be responsible,  but which will not be directly  provided
by the LLC through its employees.

         h. Patient  Records.  The Manager  shall provide to the LLC all patient
records of the LLC's  physician  employees and shall maintain and retain records
of all  professional  services  provided by the LLC to its patients  directly or
through contracts with other providers of medical professional services or other
health care  services.  The Manager  shall  maintain a complete  file within the
LLC's offices of all such medical records and supporting documents.

         i.       Marketing.  The  Manager  shall  provide to the LLC,  directly
or  through  consultants,  practice  development  assistance,  including but not
limited to advertising,  promotional and media  materials and one or more public
relations  programs  designed

                                       12

<PAGE>

to  enhance each  physician's  medical  practice and extend the LLC's ability to
provide  services  through  increased  public  awareness  of  the  LLC  and  its
Affiliates.

         j.       Utilization  Management;  Quality  Assessment and Improvement.
The  Manager shall provide ongoing reviews of the LLC's utilization  management,
and shall conduct  quality  assessment  and improvement  activities for the LLC,
including monitoring of patient satisfaction.

         k.  Regulatory  Compliance.  The Manager shall advise the LLC regarding
compliance with all applicable state and Federal laws and regulations, including
Medicare  regulations and policies  concerning primary care physician  services.
Notwithstanding  the above, it shall be the LLC's sole  responsibility to comply
with all such  applicable  state and  Federal  laws and  regulations,  including
Medicare regulations and policies concerning primary care physician services.

         l. Commercial  Reasonableness.  Notwithstanding  any other provision of
this Agreement,  all obligations of the Manager  hereunder,  including,  without
limitation,  the obligations of the Manager to provide assets,  facilities,  and
services to the LLC in connection with the LLC's Practice of Medicine,  shall be
limited,  and  shall be  interpreted  according  to, a  standard  of  commercial
reasonableness  appropriate for application to primary care Medical Practices in
the Montgomery County,  Maryland,  as determined by the Manager. The Manager, in
the performance of its obligations  hereunder,  including without limitation the
provision of assets,  facilities  and services to the LLC,  shall in no event be
required to do anything or to make  available to the LLC any asset,  facility or
service, that the Manager in good faith believes is not commercially  reasonable
and, subject to review under the provisions of Sections 7.b and 7.c hereof,  the
Manager  shall  have no duty to do,  or omit to do,  anything  that  is,  in the
discretion of the Manager, commercially unreasonable.

         m.  Disbursement  of LLC Collected Cash. The Manager shall be obligated
to, and shall,  pay the LLC's  Business Costs only out of and from the cash that
the  Manager  actually  collects  in respect of and from the LLC's  Non-Medicare
Receivables,  with  respect to which the Manager is appointed as the LLC's agent
as provided in Section 3.b hereof,  and with  respect to the LLC's  Non-Medicare
Receivables  assigned,  transferred and conveyed to the Manager pursuant to such
provision,  and with respect to any other amounts which the Manager  collects or
receives on behalf of the LLC  (collectively,  the  "Collected  LLC Cash").  The
order of priority for the use of the  Collected LLC Cash is as set forth in this
Section.

                  (i) If the  Collected LLC Cash is or will be  insufficient  to
permit the Manager to pay all of the LLC's Business Costs in the ordinary course
of business as such Business Costs accrue,  the Manager shall pay or provide for
such LLC Business Costs in the following order of priority:  first,  the Manager
will pay or provide for the payment of all LLC Business  Costs  ("Base  Business
Costs") other than the Base

                                       13

<PAGE>

Salaries,  Base  Bonuses  and Additional Bonuses of all physicians  employed  by
the  LLC  who  are  also  members  of the  LLC  ("Member  Physicians");  Second,
the  Manager  will  pay  or  provide  for the payment of all the Base Salary and
benefits  of  all  Member Physicians ("Base Salaries");  and third, the  Manager
will  pay  or  provide  for the  payment of all the Base  Bonuses and Additional
Bonuses  ("Bonuses"),  as those  terms are  defined  in each  Member Physician's
Employment  Agreement.   The  provisions  of  subsections (ii)  and (iii)  shall
govern  in  the  event  that  the  Manger  determines  that  there is or will be
insufficient Collected LLC Cash to pay Base Salaries or Bonuses.

                  (ii) During the term of this Agreement, to the extent there is
insufficient  Collected  LLC  Cash to pay to or for the  benefit  of the  Member
Physicians  the  aggregate of all Base  Salaries  (each such  deficiency a "Base
Salary  Deficiency")  with respect to any time period,  available funds shall be
applied by the Manager on behalf of the LLC to reduce the Base Salary Deficiency
in  the  following  order,  with  each  funding  source  being  depleted  before
proceeding to the next funding source:  (1) All available Net Ancillary  Service
Collections  received by the LLC; (2) The LLC's  portion of the aggregate of the
Practice Growth Amounts, as defined in each Employment Agreement; (3) Any or all
of the MCIP payment  undistributed to the LLC; (4) Any management fees earned by
the  Manager  with  respect to  Ancillary  Services  under  Section  4.b of this
Agreement; and (5) the Manager's portion of the aggregate of the Practice Growth
Amount,  discussed in Section 4.c of this Agreement. If a Base Salary Deficiency
exists after the  exhaustion  of all of the above listed  funding  sources,  the
Manager shall  nonetheless fund the amount of the Base Salary  Deficiency to the
LLC to enable the LLC to make such payments.

                  (iii) To the extent there is  insufficient  Collected LLC Cash
to pay to or for the  benefit  of the Member  Physicians  the  aggregate  of all
Bonuses  when due them with  respect to any year (each such  deficiency a "Bonus
Deficiency"),  funding  shall be applied to reduce the Bonus  Deficiency  in the
following  order,  and only to the  extent  that  Base  Business  Costs and Base
Salaries  have been funded,  with each  funding  source  being  depleted  before
proceeding to the next funding source:  (1) All available Net Ancillary  Service
Collections  received by the LLC; (2) The LLC's  portion of the aggregate of the
Practice Growth Amounts, as defined in each Employment Agreement; (3) Any or all
of the MCIP payment  undistributed to the LLC; (4) Any management fees earned by
the  Manager  with  respect to  Ancillary  Services  under  Section  4.b of this
Agreement;  and (5) the  Manager  `s portion of the  aggregate  of the  Practice
Growth Amount, discussed in Section 4.c of this Agreement. If a Bonus Deficiency
remains after the  application of the funding sources as specified  above,  then
the Manager may,  but shall not be required to, elect to advance  funding to the
LLC to pay all or a portion of the remainder of the Bonus  Deficiency,  in which
case the Manager shall have the right to offset the amount of the advance,  plus
the carrying cost of the funds,  against the amounts then or thereafter owing or
accruing to the LLC. The amount of any Bonus  Deficiency  shall, for purposes of
the calculation of the  Compensation  pursuant to Section 4 hereof,  be deemed a
"Base Business Cost" until

                                       14

<PAGE>

any funds advanced to cover any Bonus Deficiency have been paid in full.  In the
event  the  Manger  does  not  elect  to advance all or any portion of the Bonus
Deficiency to the LLC, then, unless  the  Manager  consents in writing,  the LLC
shall accrue and defer any unpaid Bonus  Deficiency  otherwise due to Physicians
as contemplated by Section 6.3 of each Employment Agreement.

                  (iv)     "Base Salary Deficiency" and "Bonus Deficiency" shall
be referred to collectively as "Physician Compensation Deficiency."

 4.      COMPENSATION OF THE MANAGER; OBLIGATIONS OF THE LLC.

         a.       Compensation.     In  consideration of the assets,  facilities
and  services  provided  by  the Manger to the LLC  pursuant to this  Agreement,
the LLC hereby  authorizes  the  Manager  to  pay to itself on behalf of the LLC
from the LLC  Accounts,  and the  Manager  shall be  entitled  to  receive  from
the  LLC,  Compensation  (the "Compensation")  calculated  and paid according to
the terms of this Section 4.

         b. Net Ancillary Services Collections. All amounts collected, billed or
derived from, or otherwise with respect to, the provision of ancillary  services
in the  LLC,  including  but not  limited  to,  laboratory  services,  radiology
services, or any other service classified as a designated health service for the
purpose of the  prohibition on physician  self-referral  contained in the Social
Security Act  ("Ancillary  Services")  shall be  considered  Ancillary  Services
Revenue.  The Manager shall calculate all direct expense of providing  Ancillary
Services (excluding any physician expense), and subtract the direct expense from
all revenue  collected  with  respect to  Ancillary  Services  to identify  "Net
Ancillary  Services Cash  Collections".  The Manager  shall  retain,  and pay to
itself on a monthly  basis,  an amount equal to forty  percent  (40%) of the Net
Ancillary  Services  Cash  Collections  as part of its  Compensation,  with  the
remaining  sixty percent (60%) being the "Net  Ancillary  Services  Collections"
which shall be credited to the account of the LLC and made  available to pay LLC
Business  Costs. To the extent that the Net Ancillary  Services  Collections are
not required to pay LLC Business  Costs due or accrued with respect to any year,
or used to pay all or a portion of any Physician  Compensation  Deficiency under
Section  3.m,  the Manager  shall pay over to the LLC the  remainder  of the Net
Ancillary  Services  Collections to the LLC for  distribution  to the physicians
following the end of any applicable  year as part of the Additional  Bonus Pool.
The LLC warrants that it shall  distribute  Net Ancillary  Services  Collections
among the physician members of the LLC in accordance with a plan of distribution
that has been  previously  adopted by the LLC and  approved  by the  Manager and
which does not, directly or indirectly, take into account the volume or value of
any referrals for such services by any physician in the LLC.

         c. Practice  Growth  Bonus.  "Practice  Growth  Amount" has the meaning
attributed  to it in Section  6.3 of each  Employment  Agreement.  At the end of
every year,  the Manager  shall  calculate  the Practice  Growth Amount for each
Member

                                       15

<PAGE>

Physician in the LLC,  and shall  retain and pay to itself  thirty-eight percent
(38%)  of  each  Member  Physician's  Practice  Growth  Amount,  as  part of its
Compensation (the "Practice Growth Bonus Amount").

         d. Base Compensation.  The amount of the Manager's Base Compensation in
each year shall be the amount  determined by (i) subtracting the total amount of
(A) all LLC Business Costs (which,  with respect to any month in which there are
Physician  Deficiencies  outstanding,  shall  include the  aggregate of all such
deficiency  amounts)  that  the  Manager  pays or is  obligated  to pay  through
disbursements  from the LLC Accounts or provides for by transfers to  reasonable
reserves  established by the Manager,  and (B) all bank fees,  charges and other
deductions from the LLC Accounts made by the depository bank,  during a calendar
month  from  (ii) the  amount of (A) all  Collected  LLC Cash  deposited  by the
Manager in the LLC  Accounts,  and (B) all interest  earned on or other  amounts
credited to the LLC Accounts by the depository bank, during such calendar month;
and (iii)  subtracting from the resulting number any amounts paid to or retained
by the Manager under the provisions of Section 4.b and 4.c above for the year in
question.  The Manager's  Compensation shall be calculated and paid on or before
the tenth day of the month  following the month for which payment is being made.
The  Manager's  Compensation  shall  be paid  only  out of  Collected  LLC  Cash
remaining in the LLC Accounts after all LLC Business Costs (which,  with respect
to any month in which  there are Base  Salary  Deficiencies  outstanding,  shall
include the aggregate of all such deficiency amounts) have been paid or provided
for,  including  the  accruing of any reserves  for the Net  Ancillary  Services
Collections  and the Practice Growth Bonus Amounts as the Manager shall consider
appropriate. Adjustments in the amount of the Compensation for any year, if any,
may be made after review of settled bank statements by the independent certified
public  accountants  retained by the Manager to review the financial  records of
LLC (which may be the Manager's accountants). The Manager shall permit the LLC's
accountants to review the Manager's calculation of its Compensation annually and
any  disagreement  or dispute  between the LLC and the  Manager  relating to the
amount of the  Compensation  resulting  from such review shall be subject to the
dispute resolution  procedures of Section 7.b and 7.c hereof. The Manager shall,
if necessary,  increase or decrease,  as the case may be, the Compensation  next
payable  after its  receipt of the  results of such  review  (including  dispute
resolution, if any) to reflect such results.

         e. General  Covenants of the LLC. The LLC acknowledges that the Manager
has undertaken to provide significant assets, facilities and services to the LLC
pursuant to this Agreement in reliance upon the LLC's undertaking  diligently to
engage, and to use its best efforts to cause its physician employees  diligently
to engage, in the Practice of Medicine.  The LLC therefore  covenants and agrees
that it will diligently  engage in the Practice of Medicine in Montgomery County
and will use its best efforts to cause its  physician  employees  diligently  to
engage in, and to devote their full-time  professional  efforts to, the Practice
of Medicine in Montgomery  County.  The LLC further covenants and agrees that it
will use its best efforts to meet or exceed the

                                       16

<PAGE>

financial,  professional service and other  standards  established  for  the LLC
in  the  business  plans  and  budgets  prepared  for the LLC by the Manager and
approved  by  the  Management  Committee  and,  in  furtherance  thereof,   will
engage, and use its best efforts to cause its physician employees to  engage, in
the Practice of Medicine in the most efficient and economical  manner  possible,
consistent  with  all  applicable  professional  and  ethical   standards  and a
standard of commercial  reasonableness  appropriate for application  to  Medical
Practices in  Montgomery  County and any other areas in which  the LLC  may have
physician  practices,  including,  specifically,  those  matters  set  forth  in
Section 4.g below.

         f. Authorization of Payments.  The LLC acknowledges and agrees that its
intent in entering  into this  Agreement  with the Manager is to secure from the
Manager all of the assets, facilities and non-physician services required by the
LLC to permit it to engage in the  Practice  of  Medicine  and,  in  furtherance
thereof, to enable and permit the Manager to pay, from the Collected LLC Cash in
the LLC Accounts,  all of the  reasonable  costs and expenses of providing  such
assets,  facilities,  and services,  however and by whomever incurred, by making
disbursements  of such  Collected  LLC Cash  directly  to  providers  of assets,
facilities or services or to the LLC or to the Manager  itself in  reimbursement
of costs or expenses  incurred  by either of them.  The LLC thus  covenants  and
agrees that the Manager shall be entitled, and is hereby authorized, to disburse
from the  Collected  LLC Cash in the LLC Accounts  such funds as are required to
pay all of the reasonable costs and expenses of providing assets, facilities and
services  directly to the LLC pursuant to this  Agreement,  it being the express
understanding  of the LLC that the Manager may provide  assets,  facilities  and
services directly to Additional  Primary Care Entities and other medical service
providers, and that such allocations of costs incurred for the direct benefit of
both the LLC and one or more  Additional  Primary Care Entities or other medical
service  providers  will be necessary.  The Manager  shall,  in its  discretion,
establish the basis for allocating  each category of direct cost and the Manager
agrees to exercise such discretion in a manner that results in the establishment
of a basis for allocation of direct costs that is reasonable and fair to the LLC
and to each  Additional  Primary  Care Entity and any other  provider  entity to
which such costs are allocated.  Disputes,  if any,  regarding such  allocations
shall be resolved first through the Quality Committee and thereafter through the
other procedures established in Sections 7.b and 7.c hereof. The Manager may, in
its discretion,  involve or join as parties to such procedures any other medical
service  provider  involved  directly  or  indirectly  in a dispute  between the
Manager  and the LLC or join  the LLC as a  party  in any  dispute  between  the
Manager and any other service provider that relates to the LLC.

         g.  Covenants  of the LLC and  each  Physician.  Without  limiting  the
foregoing  provisions  of Section 4.e above,  or the duties of any physician set
forth in any Employment  Agreement with the LLC, the LLC agrees to provide,  and
to use its best  efforts  to ensure  that each of its  physician  employees  and
contractors  provides,  at

                                       17

                           (C) Each  LLC  physician  shall  be free  to exercise
absolute  discretion  in  the  conduct  of  any  and  all  activities  which may
reasonably  be  considered  as  constituting  the  practice  of  medicine.   The
professional  responsibility  to  patients  for  the  delivery  of  health  care
services under this Agreement shall at all times remain with each LLC physician.
The  Manager  shall  not interfere with the  professional judgment of any of the
LLC's physicians in the provision of professional  health care services.

                           (D) Each  LLC   physician   shall  be   required   to
participate  in and  cooperate  with the utilization  review  programs  of third
party   payors  and  of  the  Manager.  Any  determination  under a  utilization
review  program that  services  provided or proposed  to  be  provided  are  not
medically necessary  or not  otherwise appropriate shall in no case be construed
as a substitute for the  professional  judgment of each LLC  physician;  rather,
such  findings  are  intended  to be and  shall be limited to the  determination
of  reimbursement  for  services  only,  it being  understood that all decisions
regarding  the  nature  and  extent  of  services to be provided, as well as the
choice of provider, are and will be made  exclusively  by each LLC physician and
his or her patient.

                           (E) Each  LLC  physician  agrees  that  his  or   her
practice  patterns  will be profiled and will be  reviewed  by his or her peers,
and that  participation  in any of the Manager`s  preferred   provider  networks
will  be  dependent  upon  maintaining satisfactory  profiles which  are  within
the  Manager's  and  the  Quality  Committee's  standards  of acceptable medical
practice.

                           (F) Each  LLC   physician   shall refer  patients  to
other  physicians  only  when  it is deemed to be medically necessary and in the
best interest of such patients. When referrals are required,  each LLC physician
shall  use  his  or  her  best efforts to refer  to  other  physicians  who  are
participating  in any  of the  Manager's  preferred   provider  networks then in
effect,  and  to  utilize  hospitals  and  other health care providers  that are
participating  in  any  such  preferred  provider  network;  provided,  however,
that  no  LLC  physician shall be required to refer a particular  patient to any
specific physician  or  to  admit such patient requiring hospitalization  to any
specific  hospital if such LLC  Physician,  in the good faith exercise of his or
her  professional  judgment,  believes  that  the  medical needs of such patient
would be better served elsewhere.

                           (G) Each LLC  physician  shall  accept  Managed  Care
Members  as  new patients and treat current  patients should they become Managed
Care Members,  provided  that  no  LLC  physician  shall be  required  to accept
additional  patients  if he is already working  at  full capacity, as determined
by  such  physician  and  the  LLC  jointly  in the reasonable exercise of their
discretion.

                           (H) Each  LLC  physician  shall  abide  by  decisions
resulting from utilization review programs of the Manager, the Quality Committee
and/or third party payors, subject to any applicable rights  of  reconsideration
or  review.  Each  LLC

                                       21

<PAGE>


physician shall pursue all appropriate  opportunities  for  reconsideration  and
appeal of denials of payment by third party payors.

                           (I)  Each  LLC  physician  shall   provide   to   any
designated  utilization  review  programs(s)  any  medical  or other information
necessary to conduct preadmission certification and  continued  stay  review for
all  covered  services to be rendered to Managed Care Members.

                           (J) Each LLC  physician  shall allow each third party
payor  or  its  designee  to  review  and  duplicate  any  data or other records
maintained  regarding  services  provided  under  this  Agreement  as   may   be
necessary   to   conduct  the  utilization  review  program.   Such  review  and
duplication  shall be allowed upon  reasonable  notice during  regular  business
hours  and  shall  be  subject  to  all  applicable  laws,  regulations  and the
Manager's  policies  concerning the  confidentiality of such data or records.

                           (K) Each  LLC  physician  shall  use  his or her best
efforts  to  obtain  precertification  for  those  services  designated  by  any
utilization  review program(s) as requiring precertification, and  shall use his
or  her  best  efforts  to  notify the designated utilization  review program of
emergency  or  urgent inpatient  admissions  within forty-eight (48) hours after
admission.

                           (L) Each LLC physician shall cooperate as  reasonably
required to verify that Managed Care Members are eligible for covered services.

                           (M) Each LLC  physician  shall  prepare  and maintain
appropriate  records  concerning  health  care   services  provided  under  this
Agreement.  All such records shall be maintained  in   accordance  with  prudent
record  keeping  procedures,  and  as otherwise required by law.

                           (N)  Notwithstanding  anything provided herein to the
contrary,  ownership of  and  access to all patient  records shall be controlled
by the applicable  state and federal law. All medical,  financial,  and personal
information  about  patients  reviewed  and  collected  in connection  with this
Agreement shall be held in confidence and shall not be released,  disclosed,  or
published by  the parties, their agents or employees without the written consent
of  the  patient, unless otherwise permitted by law.  Each LLC  physician  shall
be   responsible   for  supplying  any  consent  necessary  to  the  release  of
medical  records  of  patients  for  purposes  of  claims management,  including
specific  consent  to  the  release  of any records pertaining to any  patient's
alcohol or drug  addiction  or   treatment,   or  mental  health  commitment  or
treatment.

                  (xx) Full Time. Except in cases of emergency,  or as otherwise
expressly  waived by the Manager or by the LLC,  the LLC shall  ensure that each
LLC  physician  devotes his or her  full-time  practice of medicine to the LLC's
group  practice,  and shall not provide  professional  services to persons other
than the Manager and the

                                       22

<PAGE>


patients  treated  by LLC Physicians. Except as otherwise waived,  all  patients
treated   by an LLC  physician  shall be deemed to be the Manager's patients and
the Manager shall be  the owner  of the medical records for all of the Manager's
patients.

                  (xxi) Non-Contract Specialists. When referrals to a specialist
or other  physician is required,  each LLC  physician  shall use his or her best
efforts to refer to physicians who are employees of the LLC or with whom the LLC
and/or the Manager has a provider contract in effect, and, where applicable,  to
other  physicians  who  are  participating  in any of  the  Manager's  preferred
provider  networks  then in effect.  In all other cases,  each LLC physician may
select  non-contract  specialists to whom patients are referred,  based upon the
such physician's best professional judgment of patient needs.

5.       MANAGED CARE INCENTIVE PAYMENT.

         a. Creation of Managed Care Incentive Payment.  The parties acknowledge
that both the Manager's  Business  Plan and the business  plan  developed by the
Manager for the LLC  contemplate  that the LLC and its physician  employees will
shift  the  emphasis  of  their   Practice  of  Medicine   from  a   traditional
fee-for-service  model to a  managed  care  model,  and that  the  Manager  must
successfully  manage the migration of the LLC's practice to a capitated model if
it is to meet its business goals and objectives. To provide an incentive for the
LLC  and  the  physician  employees  of the  LLC to  engage  in a  managed  care
environment in the most efficient and profitable manner possible, beginning with
the calendar  year 1996,  the Manager  shall pay to the LLC, an amount,  if any,
calculated as described herein (the "Managed Care Incentive  Payment" or "MCIP")
with respect to each calendar year, or portion  thereof,  that occurs during the
term of this  Agreement  (each an "MCIP  Year").  The  Manager and the LLC shall
consult with each other as to the amount of the MCIP for each MCIP Year, subject
to the  limitations  established  in Section  5.b hereof,  and the Manager  will
negotiate  in good  faith  with the LLC in order to  assure  that all  physician
employees are  adequately  compensated  in light of the market in existence from
time to time.

         b. Calculation of Managed Care Incentive  Payment.  The Manager and the
LLC shall by  December  15th of each year agree upon an MCIP  payment to be made
out of the  Manager's  income  before  provision  for income  taxes or bonus (as
reflected on the Manager's  financial  statements) for the following year. There
shall be no MCIP  payment in any year in which the Manager  does not have income
before   provision  for  income  taxes  or  bonus  reflected  on  its  financial
statements.  The Manager  and the LLC shall agree upon an MCIP  payment for each
year that is fair to the  Manager  and the LLC.  If the  Manager and the LLC are
unable to agree upon an MCIP,  then the MCIP,  if any, with respect to such MCIP
Year shall be equal to the lesser of either (i) twenty-five percent (25%) of the
amount of the excess, if any, of (A) those operating revenues of the Manager for
the MCIP Year that are properly attributable to the provision of medical care to
patients of the LLC,  over (B)  expenses of the Manager

                                       23

<PAGE>


and  the  LLC  for  the  MCIP Year that are properly  attributable  or otherwise
allocable  to  the LLC for the MCIP year, or (ii)  twenty-five  percent (25%) of
the Aggregate Base  Salaries  of all primary  care  physicians  employed  by the
LLC during  such MCIP year.   The Manager  shall have no obligation to negotiate
for an MCIP in excess of either of such  amounts.  The  Manager  shall  have the
right in its discretion to make appropriate year to year and period  adjustments
to accurately reflect income and expenses,  and to  allocate expenses among  the
LLC  and  any  other  Additional  Primary  Care  Entities, independent  practice
association  or  other  person or entity for which it serves as manager,  and to
set off  against the  amount of  any MCIP  payment  all  or any  portion  of the
amount of its costs  and  expenses resulting  from  a breach  by  any  Physician
or  any  Physician's  PC of  any representation, warranty  or  covenant  made by
such  Physician  or PC in the Practice Participation Agreement."

         c. Payment of Managed Care Incentive Payment. The Manager shall pay the
MCIP, if any, with respect to each MCIP Year to the LLC on or before February 15
of the calendar year  following  each such MCIP Year,  beginning on February 15,
1997. If, pursuant to Section 4.d hereof,  an adjustment is made in a succeeding
calendar year with respect to any  Management Fee paid to the Manager in a prior
MCIP Year,  no  adjustment  shall be made in the MCIP for the MCIP Year in which
the  Management Fee which was  subsequently  adjusted was actually paid and such
adjustments  shall be given  effect in the MCIP for the MCIP Year in which  they
were actually made.

  6.     TERM AND TERMINATION.

         a. Term.  This  Agreement  shall  commence  as of the date first  above
written,  and shall  continue in force until  December 31, 2025,  unless  sooner
modified or terminated as provided herein. This Agreement shall automatically be
renewed  thereafter  for additional  terms (each an  "Additional  Term") for ten
years each in the sole  discretion of the Manager,  so long as there is no event
of default with respect to the Manager's  performance of its duties hereunder as
set forth in Section 6.b of this Agreement.

         b.       Termination.   This  Agreement  may  be   terminated   by  the
non-defaulting  party upon the occurrence of any  of  the  following  events  of
default:

                  i. The commencement of any voluntary or involuntary case under
the Federal  bankruptcy laws or any state insolvency or similar laws seeking the
liquidation or  reorganization  of either party hereto,  or the appointment of a
receiver,  liquidator,  assignee,  custodian,  trustee or similar  official  for
either party or the property of either party or the making by either party of an
assignment  for the  benefit of its  creditors  (except  that in the case of any
involuntary  action against either party,  such party shall have sixty (60) days
to have such case  dismissed),  or the failure by either party  generally to pay
its debts as they mature.

                                       24

<PAGE>

                  ii.   Either  party  hereto  is  indicted  upon  a  charge  of
committing any felony or committing a misdemeanor which involves  allegations of
fraud,  embezzlement,  conversion or other similar act or admits engaging in, or
is  found  in a duly  convened  arbitral  proceeding  or a  court  of  competent
jurisdiction to have engaged in, illegal or other wrongful conduct substantially
detrimental to the business or reputation of the other party.

                  iii.  The  continued  refusal  by, or manifest  inability  of,
either party to perform any of the material  duties,  or to discharge any of the
material obligations, of such party pursuant to this Agreement in a professional
and reasonably  competent  manner  (consistent  with applicable  professional or
business  standards)  for a period of at least ninety (90) days after receipt of
written notice from the other party to such party providing reasonable detail as
to the specific  material duties or obligations  that are not being, or have not
been,  performed or discharged by such party in a  professional  and  reasonably
competent manner and providing a reasonable opportunity to such party to address
such  failures or  omissions  and in good faith to attempt to cure or  otherwise
begin to effect a remedy of such  failures or omissions  within such ninety (90)
day period; provided,  however, that the LLC may not terminate this Agreement so
long as the Manager is in good faith  attempting  to address any such failure or
omission and it appears  reasonably  possible  that such failure or omission may
(or will) be cured before irreparable  material harm or other significant injury
occurs to the LLC and,  provided  further,  that the LLC may not terminate  this
Agreement  if any lender  to, or holder of a senior  security  of,  the  Manager
arranges,  or is  arranging  for,  an  assignment  or  transfer  of  such of the
Manager's  duties  hereunder  as to which the Manager is in actual or  potential
default to another  management  entity with  experience in managing  health care
providers that is reasonably acceptable to the LLC.

         c.       Effect of Termination.

                  i. Upon the  occurrence of an event of default by the LLC, the
Manager  shall  have the  right  without  further  notice  to  reenter  and take
possession of the Demised  Premises,  or any part thereof,  and to repossess the
same as the  Manager's  former  estate,  and expel  the LLC and  those  claiming
through or under the LLC, and remove the effects of either or both without being
deemed  guilty of any manner of trespass  and without  prejudice to any remedies
for arrears of fees due or preceding breaches of this Agreement.

                  ii. Upon the occurrence of an event of default by the Manager,
the LLC shall have the right to  continue in full  possession  and use of all of
the  assets,  facilities  and goods  provided  to it by the  Manager,  including
without limitation the Office Space and the Equipment,  and to purchase from the
Manager for their  appraised  fair market value all of the assets of the Manager
constituting  the Demised  Premises and any other of the Manager's  assets which
the LLC, in its sole discretion,  deems necessary or desirable to permit the LLC
to continue its Practice of Medicine without

                                       25

<PAGE>

interruption,  it  being  the  intent of the  parties to permit  the LLC in such
event  to  continue  its  Practice  of  Medicine  with  as  little disruption as
possible.  The  LLC  shall be entitled to set off against the purchase  price it
pays for the  Manager's  assets the amount of any  damages  incurred  by the LLC
as a result of the  Manager's  breach of this Agreement.

 7.      MODIFICATIONS; QUALITY COMMITTEE; ARBITRATION.

         a.  Modification  for Prospective  Legal Events.  If, in the good faith
opinion of either party,  as supported by the written opinion of counsel to such
party,  any  Federal or state laws or  regulations  now  existing  or  hereafter
promulgated or enacted,  including specifically without limitation Medicare, are
interpreted by judicial  decision,  a regulatory  agency or legal counsel in any
manner as to  indicate  that the  structure  of this  Agreement,  or any portion
thereof, may be in violation of such laws or regulations, such party may require
the parties hereto to use their respective best efforts to amend this Agreement,
or such portions hereof, to the extent necessary to avoid further violation.  To
the maximum extent  possible,  any such amendment  shall preserve the underlying
economic and financial risks, rewards and other arrangements set forth herein. A
party  requesting  such an amendment  shall give written  notice  thereof to the
other party which shall set out in sufficient detail the basis for the amendment
request and specifically  identify the specific provisions of this Agreement for
which  renegotiation  is sought.  Within  thirty (30) days of its receipt of the
requesting  party's notice,  the other party shall give notice to the requesting
party of any additional provisions of this Agreement as to which the other party
requests renegotiation and the reasons therefor. No provisions of this Agreement
other than those specifically  designated by the parties for renegotiation shall
be  affected by the  renegotiations.  Should the parties be unable to agree upon
mutually  acceptable  revisions to this Agreement  within ninety (90) days after
receipt by the other party of the initial  request for  renegotiation,  then the
matters that remain unresolved  through  renegotiation  pursuant to this Section
7.a shall be  submitted to binding  arbitration  pursuant to the  provisions  of
Section 7.c hereof. Each of the foregoing time periods shall be shortened if and
to the extent  necessary  to avoid a  violation  of  applicable  law in a timely
manner.

         b. Quality Committee. The Manager and the LLC hereby create the Quality
Committee  referred to in this  Section  7.b for the  purpose of (i)  developing
cooperative developmental,  management and administrative policies to guide each
of the LLC  and the  Manager  in  fulfilling  its  obligations  hereunder,  (ii)
providing to the Manager and the LLC a forum in which policy and  implementation
matters  affecting  the LLC and its  physicians  may be  discussed  on a regular
basis,   and  (iii)   establishing  an  expedited   process  through  which  any
disagreement  or dispute  between the parties to this  Agreement  relating to or
concerning  (A)  the  quality,   adequacy  or  appropriateness  of  the  assets,
facilities  or services  provided by the Manager to the LLC, (B) the quality and
timeliness  of the services  provided by the LLC and its  physicians to patients
pursuant to this  Agreement,  (C) the  appropriateness  of any expense which the
Manager  treats as a Business  Cost of the LLC, may be submitted  for review and
resolution prior to any

                                       26

<PAGE>

informal  or  formal  adjudication.  The  Quality Committee shall consist of six
members,  three  appointed  by the LLC and three appointed by the  Manager.  The
three  members  appointed  by the Manager  shall be the Chief Executive  Officer
of the Manager,  the  Executive  Vice President and Director of Medical Services
of the Manager and the Executive Vice President  and Director of Legal  Services
of the Manager.  Of the three members  appointed  by  the  LLC, one shall be the
President of the LLC or his  designee.  Either party may change  the designation
of  any  of  its  Quality  Committee  members  who  is  not  serving  ex-officio
by written  notice  delivered  to the other  party  pursuant  to the  provisions
of Section 10.p of this Agreement.

                  The Manager  and the LLC agree to cause the Quality  Committee
to meet  regularly,  but not less  often  than  monthly.  Where  possible,  such
meetings  shall  be  scheduled  to  coincide  with the  dates  of the  regularly
scheduled  meetings of the Manager's Board of Directors.  The Quality  Committee
shall adopt such rules and regulations  regarding the conduct of its business as
it deems appropriate.

                  If the LLC  believes  that  any  asset,  facility  or  service
provided by the Manager to the LLC  pursuant to this  Agreement,  including  any
item of  Equipment,  any aspect of the Office  Space,  any goods,  materials  or
supplies or any  administrative  or other  service,  including any aspect of any
budget,  business  plan,  policy or  procedure,  or any of the  professional  or
non-professional personnel provided to the LLC, is inadequate,  inappropriate or
otherwise  insufficient,  then the LLC shall give written  notice thereof to the
Manager,  setting out in sufficient detail the basis for the LLC's position.  If
the Manager  believes that the quality or timeliness of the care provided to any
patient does not meet the standards  established  herein and in each physician's
Professional Services Employment  Agreement,  or that the LLC is not cooperating
in such reasonable efforts of the Manager to create a fully integrated efficient
health care delivery system as herein contemplated,  then the Manager shall give
written notice thereof to the LLC which shall set forth in sufficient detail the
basis for the Manager's  position.  The Quality Committee shall, within ten (10)
days of the date of any such  notice,  convene a special  meeting and shall,  in
good faith endeavor to resolve the issues raised in such notice by agreeing upon
a unanimous  recommendation with respect to such issues, which shall be reported
back to the Manager and the LLC. If within  thirty (30) days of the date of such
notice there has been no joint recommendation, or both parties have not accepted
in  writing  a joint  recommendation  of the  Quality  Committee  as a basis for
resolving all such issues, the unresolved issues may be referred by either party
to  arbitration  pursuant to the  provisions  of Section  7.c hereof.  Any joint
recommendation  of the Quality  Committee  members which is accepted by both the
LLC and the Manager shall be promptly implemented.

         c.  Arbitration.  Any dispute  between  the  parties of this  Agreement
arising  under or with  respect to this  Agreement,  or any matters  referred to
arbitration  pursuant  to the  terms of  Sections  7.a or 7.b  hereof,  shall be
submitted to binding arbitration according to the procedures set out on Schedule
13.1 of the Practice  Participation

                                       27

Agreement of even date herewith,  among the LLC, the Manager and other  Parties,
the  provisions  of  the  said  Schedule 13.1  being  hereby  incorporated  into
and as a part of this  Agreement  by  express reference.   Each Party  agrees to
abide by the time periods and other rules said forth in the said Schedule  13.1.
The  resolution  of  any  disputes  through such procedures,  including  without
limitation  through  arbitral  award,  shall  be  binding   upon the Parties for
all  purposes  and may be enforced in any court of competent jurisdiction.

  8.     CONFIDENTIALITY AND EXCLUSIVITY.

         a.       The Manager's Obligations.

                  i. The Manager shall,  and shall use its best efforts to cause

prior written consent of the Management Committee, contract for the provision of
such services or provide such services to any provider of medical  services that

the  LLC's  service  area as  determined  by the  Manager  from  time to time in
consultation with the LLC and,  provided further,  that the Manager shall at all
times preserve the  confidentiality  of the LLC's  financial,  professional  and
other information.

         b.       The LLC's Obligations.

effect the non-competition (and other) provisions of each Professional  Services
Employment  Agreement,  will not,  without  the  prior  written  consent  of the
Manager,  enter into employment  agreements or other contracts with primary care
physicians that do not contain substantially  similar provisions,  and will take
any and all steps  requested  or  required by the Manager to enforce any and all
such provisions as drafted.  To this end. the LLC hereby appoints the Manager as
its attorney-in-fact  for purposes of enforcing,  on behalf of the LLC, all such
provisions as drafted.

Agreement for any reason whatsoever,  each party shall immediately turn over all
confidential information of the other party in its possession and control to the
other  party,  and  shall  refrain  from  thereafter  using,   appropriating  or
reproducing such information in any form whatsoever.

         d. Enforcement.   Each  party  agrees  that  the  other  party shall be
entitled to  seek  equitable  relief  to enjoin the actual or threatened  breach
of  the  confidentiality   and   exclusivity   obligations  of  this  Article  8

either from or pursuant to the arbitration provisions of  Section  7.c hereof or
pre-arbitral  injunctive  relief  from a court of  competent jurisdiction  prior
to the selection of an arbitral panel.

including  the   distribution  of  professional  fee  income   or  distributions
of Managed  Care Incentive  Payments,  if any, among the individual Members  and
other  physicians  of  the  LLC,  tax  planning,  and   pension   and investment

desirable pursuant to the terms of this Agreement.

         n.  Further  Cooperation.  The LLC shall  cooperate  and  execute  such
agreements  and cause such of its  physician  employees  as may be  necessary to
become participating providers in such third-party reimbursement programs as the
Manager  may  from  time to time  direct.  As used in this  Agreement,  the term
"third-party reimbursement program" shall include, but not be limited to, health
maintenance  organizations,  preferred  provider  organizations,  private health
insurance  companies,  Blue  Cross/Blue  Shield,  the Federal and State Medicare
and/or  Medicaid  programs,  and any other managed care plan. The LLC shall also
cooperate with the Manager in promotional  programs developed or selected by the
Manager.

Closing  Documents  constitute  the  complete  understanding  of the parties and
supersede  any and all other  agreements,  written or oral,  between the parties

attached hereto as Exhibit A (the "Lease"),  [Add appropriate recitals regarding
leases from  Physicians  and/or PCs,  to the LP, to DHS]  ___________,  Maryland

Tenant desires to  sublease  the Premises to Subtenant, on the terms and subject
to the conditions which are hereinafter set forth.

         [C.      Landlord  joins  in the execution of this Sublease to evidence
its consent to the  within Sublease, as required by Section ______ of the Lease.
Where appropriate.]

         NOW, THEREFORE,  FOR AND IN CONSIDERATION of the mutual entry into this
Sublease by the parties  hereto and for other good and  valuable  consideration,
the  receipt  and  sufficiency  of which are hereby  acknowledged  by each party

Tenant all of the Premises in its "as is" physical  condition  (Subtenant having

expiration date of the renewal term less one (1) day (the "Extended Term") (both
the Initial Term and the Extended Term shall be collectively

                                       35

         2.  Rental.  Subtenant  shall pay to Tenant,  without  prior  notice or

"Rent"),  the amount of  ________  Dollars  ($__________)  per month  during the
Term..  Rent shall be prorated on a daily basis for any partial  calendar  month

thereof,  unless such  replacement is due to  Subtenant's  negligence or willful
misconduct), pay taxes, insurance, and operating expenses, and any and all other
charges  due  and  payable  in  connection  with  the  occupancy  and use of the
Premises,  including,  but not limited to, those  payable to Landlord  under the

employees.

         3.  Obligations of Tenant and Subtenant Under the Lease.

                  3.1.  In addition  to any other  obligations  that are imposed
upon Subtenant  under the provisions of this Sublease,  Subtenant shall abide by
any restriction placed on Tenant pursuant to the terms of the Lease.

                  3.2.  In  addition  to any  other  rights  that  are  held  by
Subtenant under the provisions of this Sublease, Subtenant shall have all of the
same rights  hereunder  against Tenant as Tenant has against  Landlord under the
provisions of the Lease, and, except for the services to be provided by Landlord
to  Tenant  under  the  Lease,  Tenant  shall  have all of the same  obligations
hereunder  to  Subtenant  as  Landlord  to  Tenant  under the  Lease,  all as if
provisions  identical  to such  provisions  were  set  forth at  length  in this
Sublease.

                  3.3.   Without   limiting  the  generality  of  the  foregoing
provisions of this Section,  3.3.1. Subtenant covenants and agrees not to commit
any act that  shall  cause  Tenant to be in breach  of any  term,  covenant,  or
condition  under  the  Lease  or  interfere  with  Tenant's  performance  of its
obligations or duties under the Lease;

                  3.3.2. in any instance in which Tenant has any right under the
provisions  of the  Lease  to give  or  withhold  its  approval  of any  action,
omission,  or other  matter,  or has any  other  discretionary  right  under the
provisions of the Lease,  Tenant shall

                                       36

<PAGE>

exercise  such  right  in  each  instance  in a manner that is  consistent  with
Subtenant's  rights and  Tenant's  obligations hereunder, and

                  3.3.3.  in any such  instance in which Tenant may exercise any
such  right  in two  (2) or  more  ways,  neither  or none  of  which  would  be
inconsistent  with  Subtenant's  rights and Tenant's  obligations,  Tenant shall
notify Subtenant thereof in writing,  and shall exercise any right in accordance
with Subtenant's written instructions to Tenant; provided,  however, that Tenant
must receive such  instructions  within such period, if any, during which Tenant
may be required by the provisions of the Lease to exercise or waive such right.

         4.  Amendment and Termination of Lease.

                  4.1.  Tenant shall not amend,  or consent to any amendment of,
the Lease in any respect that materially and adversely affects Subtenant's right
to use and enjoy the  Premises on the terms and subject to the  conditions  that
are contained in this Sublease. No amendment of the Lease shall operate to alter
or impair Subtenant's rights hereunder.

                  4.2.  If the Lease  terminates  for any reason  this  Sublease
shall thereupon automatically terminate  simultaneously with such termination of
the Lease, and no party hereto shall have any right hereunder  against any other
party  hereto  on  account  thereof;  provided,  however,  that  nothing  in the
foregoing  provisions  of this  sentence  shall be deemed in any way to alter or
impair any liability that any party hereto may have to any other accruing before
such termination.

                  4.3.  If the Lease  terminates  as a result  of a  default  by
Tenant in performing its obligations  thereunder,  the parties hereto shall have
such rights and  liabilities to each other  hereunder on account of such default
as exist under applicable law.

                  4.4.  On  the  expiration  or  earlier   termination  of  this
Sublease, the rights and obligations of Landlord and Tenant shall be governed by
the  Termination of Lease  Agreement by and between  Landlord and Tenant of even
date herewith.

         5. Notices. Any notice, demand,  consent,  approval,  request, or other
communication  or document to be provided  hereunder  to a party hereto shall be

         3.1.      ORGANIZATION AND STANDING

                  The Company is a corporation duly organized, validly existing

state,  country or territory  wherein the absence of  registration  as a foreign
corporation  would have a  material  adverse  effect  upon the  business  of the
Subsidiaries as currently conducted.


         3.3.      ARTICLES OF INCORPORATION AND BYLAWS

                  The Company has delivered to the Investor (i) a true and

                  The obligations and liabilities of the Company and the
Investor hereunder with respect to their respective indemnities pursuant to this
SECTION 11, resulting from any Claim shall be subject to the following terms and
conditions:

                  (a) The indemnified party shall give prompt written notice to
the indemnifying party of any Claim which is asserted against, resulting to,
imposed upon or incurred by such indemnified party and which may give rise to
liability of the indemnifying party pursuant to this SECTION 11, stating (to the
extent known or reasonably anticipated) the nature and basis of such Claim and
the amount thereof.

                  (b) The indemnifying party shall engage counsel with respect
to any such Claim, such representation (including the compromise or settlement
of any Claim) to be undertaken on behalf of the indemnified party, and the
indemnified party shall have right to approve such counsel (such approval not to

undertake such defense by its own counsel, the indemnifying party shall give
prompt written notice of such election to the indemnified party, and the
indemnified party will undertake the defense thereof by counsel or other
representatives designated by it, at the cost and expense of the indemnifying
party (such costs and expenses of such defense to be advanced by the
indemnifying party as incurred by the indemnified party).

                  (c) In the event that any Claim shall arise out of a
transaction or cover any period or periods wherein the Company, on the one hand,
and the Investor, on the other hand, shall each be liable hereunder for part of
the liability or obligation arising therefrom, then the parties shall, each
choosing its or his own counsel and bearing its or his own expense, defend such
Claim, and no settlement or compromise of such Claim may be made without the
joint consent or approval of each party (which consent shall not be unreasonably
withheld), except where the respective liabilities and obligations of the
parties are clearly allocable or attributable on the basis of objective facts.

                  (d) The amount which any indemnifying party is or may be
required to pay any indemnified party pursuant to this SECTION 11 shall be
measured taking into account (i) any income tax savings (and income tax cost
attributable to the indemnity payment) actually realized (or occurred) that
affect the overall economic impact of the losses to the indemnified party, and
(ii) any insurance proceeds actually realized and adverse insurance consequences
incurred (such as premium adjustments and other detriments) that affect the
overall economic impact of the losses to the indemnified party.

registration rights to the Holder upon the terms and conditions set forth in
this Agreement.

                           (b) Registrable Securities. For the purposes of this

                  3. Demand Registration.

                           (a) Request for Demand Registration. At any time
beginning 180 days after the conversion of the Series C Preferred Stock in
connection with a Public Offering, the Holder may make a written request to the
Company to register, under the Securities Act (other than pursuant to a
registration statement on Form S-4 or S-8 or any successor thereto) and under
the securities or "blue sky" laws of any jurisdiction designated by such Holder
(a "DEMAND REGISTRATION"), the number of Registrable Securities stated in such
request. The Company shall not be obligated to effect more than one (1) Demand
Registration pursuant to this Section 3 on Form S-1 under the Securities Act or
any successor form or similar

                                       4

<PAGE>

long-form registration or, if available, on Form S-2 or S-3 or any similar
short-form registration. If at the time of any request to register Registrable
Securities pursuant to this Section 3(a), the Company is engaged in, or has
fixed plans to engage in within sixty (60) days of the time of such request, a
Public Offering or is engaged in any other activity which, in the good faith
determination of the Board of Directors of the Company, would be materially
adversely affected by the requested registration to the material detriment of
the Company, then the Company may at its option direct that such request be
delayed for a reasonable period not in excess of ninety (90) days from the
effective date of such offering or the date of completion of such other material
activity, as the case may be. In addition, the Company shall not be required to
effect more than one registration on behalf of all persons who have been granted
registration rights by the Company in any 12 month period or any registration
within one hundred twenty (120) days after the effective date of any other
Registration Statement of the Company. A request for a Demand Registration shall
state the amount of the Registrable Securities proposed to be sold and the
intended method of disposition thereof. Upon a request for a Demand
Registration, the Company shall promptly take such steps as are necessary or
appropriate to prepare for the registration of the Registrable Securities to be
registered.

                           (b) Incidental or "Piggy-Back" Rights with Respect to
a Demand Registration. The Holder may offer its Registrable Securities under any
demand registration pursuant to any other registration rights agreement or other
similar agreement between the Company and any other holder of the Company's
securities. Within ten (10) days after the receipt of a request for such demand
registration, the Company shall (i) give written notice thereof to the Holder
and (ii) subject to Section 3(e), include in such registration all of the
Registrable Securities held by the Holder from whom the Company has received a
written request for inclusion therein within ten (10) days of the receipt by the
Holder of such written notice referred to clause (i) above. Each such request by
the Holder shall specify the number of Registrable Securities proposed to be
registered and the intended method of disposition thereof.

                           (c) Effective Demand Registration. A registration
shall not constitute a Demand Registration until it has become effective and
remains continuously effective for the lesser of (i) the period during which all
Registrable Securities registered in the Demand Registration are sold and 
(ii) 120 days; provided, however, that a registration shall not constitute a 
Demand Registration if (x) after such Demand Registration has become effective,
such registration or the related offer, sale or distribution of Registrable
Securities thereunder is interfered with by any stop order, injunction or other
order or requirement of the SEC or other governmental agency or court for any
reason not attributable to the Holder and such interference is not thereafter
eliminated or (y) the conditions to closing specified in the underwriting
agreement, if any, entered into in connection with such Demand Registration are
not satisfied or waived other than by reason of a

                                       5

<PAGE>

failure by the Holder or (z) the Company sells for its account at least one-half
of the shares included in the registration.

                           (d) Expenses. In any registration initiated as a
Demand Registration, the Company shall pay all Registration Expenses (other than
underwriting discounts and commissions) in connection therewith, whether or not
such Demand Registration becomes effective.

                           (e) Underwriting Procedures. If the holders of a
majority in aggregate amount of the Registrable Securities to be included in the
Demand Registration so elects, the offering of Registrable Securities pursuant
to such registration shall be in the form of a firm commitment Public Offering
and the managing underwriter or underwriters selected for such offering shall be
the Approved Underwriter (as hereinafter defined) selected in accordance with
Section 3(f). In connection with any Demand Registration under this Section 3
involving an underwriting, none of the Registrable Securities held by any Holder
shall be included in such underwriting unless such Holder accepts the terms of
the underwriting as agreed upon by the Company, Genesis and the Approved
Underwriter, and then only in such quantity as will not, in the opinion of the
Approved Underwriter, jeopardize the success of such Public Offering by the
Holder. If the Approved Underwriter advises the Company in writing that in its
opinion the aggregate amount of such Registrable Securities requested to be
included in such Public Offering is sufficiently large to have a material
adverse effect on the success of such Public Offering, then the Company shall
include in such registration only the aggregate amount of Registrable Securities
that in the opinion of the Approved Underwriter may be sold without any such
material adverse effect and the amount of such shares that may be included in
such registration shall be reduced first by any shares proposed to be sold in
such Public Offering by the Company's executive officers (the "MANAGEMENT
STOCKHOLDERS"), second by any shares proposed to be sold by shareholders other
than the Holder and the Management Stockholders, third by any shares proposed to
be sold by the Company and fourth by a further amount to the Holder.

                           (f) Selection of Underwriters. If any Demand
Registration of Registrable Securities is in the form of an underwritten
offering, the managing underwriter for such Public Offering (the "APPROVED
UNDERWRITER") shall be chosen by the holders of a majority of the aggregate
Registrable Securities being registered; provided, however, that the Approved
Underwriter shall be acceptable to the Company in its reasonable judgment.

                  4. Incidental or "Piggy-Back" Registration.

                           (a) Request for Incidental Registration. At any time
the Company proposes to file a Registration Statement under the Securities Act
with respect to an offering by the Company for its own account (other than a
registration

                                       6

<PAGE>

statement on Form S-4 or S-8 or any successor thereto), then the Company shall
give written notice of such proposed filing to the Holder at least thirty (30)
days before the anticipated filing date, and such notice shall describe the
proposed registration and distribution and offer the Holder the opportunity to
register the number of Registrable Securities as the Holder may request (an
"INCIDENTAL REGISTRATION") in writing. The Company shall, and shall use its best
efforts (within ten (10) days of the notice provided for in the preceding
sentence) to cause the managing underwriter or underwriters of a proposed Public
Offering (the "COMPANY UNDERWRITER") to permit the Holder to include its
Registrable Securities in such Public Offering on the same terms and conditions
as the securities of the Company included therein; provided, however, that the
Company shall not be obligated to effect more than three (3) Incidental
Registrations pursuant to this Section 4, not including any Incidental
Registration in which the Company, based on the opinion of the Company
Underwriter, does not include any Registrable Securities which the Holder has
requested to be included. In connection with any Incidental Registration under
this Section 4(a) involving an underwriting, the Company shall not be required
to include any Registrable Securities in such underwriting unless the holders
thereof accept the terms of the underwriting as agreed upon between the Company
and the Company Underwriter, and then only in such quantity as will not, in the
opinion of the Company Underwriter, jeopardize the success of the Public
Offering by the Company. If in the written opinion of the Company Underwriter
the registration of all or part of the Registrable Securities which the Holder
has requested to be included would materially adversely affect such Public
Offering, then the Company shall be required to include in such Incidental
Registration, to the extent of the amount that the Company Underwriter believes
may be sold without causing such adverse effect; first, all of the securities to
be offered for the account of the Company; second, the Registrable Securities to
be offered for the account of the Holder pursuant to this Section 4 and any
other securities requested to be included in such underwriting (other than
securities to be offered for the account of any of the Management Stockholders),
pro rata (in accordance with the proportion that the Fair Market Value of all
securities proposed to be included in such registration by each holder bears to
the Fair Market Value of all securities proposed to be included in such
registration by Holder and all other Persons exercising incidental registration
rights in such registration); and third; all securities to be offered for the
account of the Management Stockholders.

                           (b) Expenses. The Company shall bear all Registration
Expenses (other than underwriting discounts and commissions) in connection with
any Incidental Registration pursuant to this Section 4, whether or not such
Incidental Registration becomes effective; provided, however, that the Holder
shall bear the costs of its own legal counsel.

                  5. Holdback Agreements.

                           (a) Restrictions on Public Sale by the Holder. In the
event that the Company effects a Public Offering in which shares of the
Company's Common Stock are sold to one or more Underwriters, the Holder agrees,
if requested by the managing underwriters, not to effect any public sale or
distribution, including any sale pursuant to Rule 144 under the Securities Act,
of any equity securities (except as part of such Public Offering) during the
15-day period prior to the requested effective date of the registration
statement for such offering and during the 120-day period commencing with the
actual effective date of the registration statement for such offering.

                           (b) Restrictions on Public Sale by the Company. The
Company agrees not to effect any public sale or distribution of any of its
securities, or any securities convertible into or exchangeable or exercisable
for such securities (except pursuant to registrations on Form S-4 or S-8 or any
successor thereto), during the 15-day period prior to the requested effective
date of the registration statement for such offering and during the period
beginning on the actual effective date of any Demand Registration and ending on
the earlier of (i) the date on which all Registrable Securities registered on
such registration statement are sold and (ii) 120 days after the effective date
of such registration statement.

                  6. Registration Procedures.

                           (a) Obligations of the Company. Whenever registration

registration and sale of such Registrable Securities in accordance with the
intended method of distribution thereof as quickly as practicable, and in
connection with any such request, the Company shall, as expeditiously as
possible:

         with the SEC a registration statement on any form for which the Company
         then qualifies or which counsel for the Company shall deem appropriate
         and which form shall be available for the sale of such Registrable
         Securities in accordance with the intended method of distribution
         thereof, and use its best efforts to cause such registration statement
         to become effective; provided, however, that (x) before filing a
         registration statement or prospectus or any amendments or supplements
         thereto, the Company shall provide counsel selected by the holders
         holding a majority of the Registrable Securities being registered in
         such registration ("HOLDERS' COUNSEL") and any other Inspector (as
         hereinafter defined) with an adequate and appropriate opportunity to
         participate in the preparation of such registration statement and each
         prospectus included therein (and each amendment or supplement thereto)
         to be filed with the SEC, which documents shall be subject to the
         review of

                                       8

         Holders' Counsel, and (y) the Company shall notify the Holders' Counsel
         and each seller of Registrable Securities of any stop order issued or
         threatened by the SEC and take all reasonable action required to
         prevent the entry of such stop order or to remove it if entered;

                                    (ii) prepare and file with the SEC such
         amendments and supplement to such registration statement and the
         prospectus used in connection therewith as may be necessary to keep
         such registration statement effective for the lesser of (x) twenty-four
         (24) months and (y) such shorter period which will terminate when all
         Registrable Securities covered by such registration statement have been
         sold, and comply with the provisions of the Securities Act with respect
         to the disposition of all securities covered by such registration
         statement during such period in accordance with the intended methods of
         disposition by the sellers thereof set forth in such registration
         statement;

                                    (iii) as soon as reasonably possible,
         furnish to each seller of Registrable Securities, prior to filing a
         registration statement, copies of such registration statement as is
         proposed to be filed, and thereafter such number of copies of such
         registration statement, each amendment and supplement thereto (in each
         case including all exhibits thereto), the prospectus included in such
         registration statement (including each preliminary prospectus) and such
         other documents as each such seller may reasonably request in order to
         facilitate the disposition of the Registrable Securities owned by such
         seller;

                                    (iv) use its best efforts to register or
         qualify such Registrable Securities under such other securities or
         "blue sky" laws of such jurisdictions as any seller of Registrable
         Securities may request, and to continue such qualification in effect in
         such jurisdiction for as long as permissible pursuant to the laws of
         such jurisdiction, or for as long as any such seller requests or until
         all of such Registrable Securities are sold, whichever is shortest, and
         do any and all other acts and things which may be reasonably necessary
         or advisable to enable any such seller to consummate the disposition in
         such jurisdictions of the Registrable Securities owned by such seller;
         provided, however, that the Company shall not be required to 
         (x) qualify generally to do business in any jurisdiction where it would
         not otherwise be required to qualify but for this Section 6(a)(iv), 
         (y) subject itself to taxation in any such jurisdiction or (z) consent
         to general service of process in any such jurisdiction;

                                    (v) use its best efforts to cause the
         Registrable Securities covered by such registration statement to be
         registered with or approved by such other governmental agencies or
         authorities as may be necessary by virtue of the business and
         operations of the Company to enable

                                       9

<PAGE>

         the seller or sellers of Registrable Securities to consummate the
         disposition of such Registrable Securities;

                                    (vi) notify each seller of Registrable
         Securities at any time when a prospectus relating thereto is required
         to be delivered under the Securities Act, upon discovery that, or upon
         the happening of any event as a result of which, the prospectus
         included in such registration statement contains an untrue statement of
         a material fact or omits to state any material fact required to be
         stated therein or necessary to make the statements therein not
         misleading in light of the circumstances under which they were made,
         and the Company shall promptly prepare a supplement or amendment to
         such prospectus and furnish to each seller a reasonable number of
         copies of a supplement to or an amendment of such prospectus as may be
         necessary so that, after delivery to the purchasers of such Registrable
         Securities, such prospectus shall not contain an untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading in
         light of the circumstances under which they were made;

                                    (vii) enter into and perform customary
         agreements (including an underwriting agreement in customary form with
         the Approved Underwriter or Company Underwriter, if any, selected as
         provided in Section 3 or Section 4, as the case may be) and take such
         other actions as are prudent and reasonably required in order to
         expedite or facilitate the disposition of such Registrable Securities;

                                    (viii) make available for inspection by any
         seller of Registrable Securities, any managing underwriter
         participating in any disposition pursuant to such registration
         statement, Holders' Counsel and any attorney, accountant or other agent
         retained by any such seller or any managing underwriter (each, an
         "INSPECTOR" and collectively, the "INSPECTORS"), all financial and
         other records, pertinent corporate documents and properties of the
         Company and its subsidiaries (collectively, the "RECORDS") as shall be
         reasonably necessary to enable them to exercise their due diligence
         responsibility, and cause the Company's and its subsidiaries' officers,
         directors and employees, and the independent public accountants of the
         Company, to supply all information reasonably requested by any such
         Inspector in connection with such registration statement. Records that
         the Company determines, in good faith, to be confidential and which it
         notifies the Inspectors are confidential shall not be disclosed by the
         Inspectors unless (x) the disclosure of such Records is necessary to
         avoid or correct a misstatement or omission in the registration
         statement, (y) the release of such Records is ordered pursuant to a
         subpoena or other order from a court of competent jurisdiction or 
         (z) the information in such Records was known to the Inspectors on a
         non-confidential basis prior to its disclosure by the

                                       10

<PAGE>


         Company or has been made generally available to the public. Each seller
         of Registrable Securities agrees that it shall, upon learning that
         disclosure of such Records is sought in a court of competent
         jurisdiction, give notice to the Company and allow the Company, at the
         Company's expense, to undertake appropriate action to prevent
         disclosure of the Records deemed confidential;

                                    (ix) if such sale is pursuant to an
         underwritten offering, use its best efforts to obtain a "cold comfort"
         letter from the Company's independent public accountants in customary
         form and covering such matters of the type customarily covered by "cold
         comfort" letters as Holders' Counsel or the managing underwriter
         reasonably request;

                                    (x) use its best efforts to furnish, at the
         request of any seller of Registrable Securities on the date such
         securities are delivered to the underwriters for sale pursuant to such
         registration or, if such securities are not being sold through
         underwriters, on the date the registration statement with respect to
         such securities becomes effective, an opinion, dated such date, of
         counsel representing the Company for the purposes of such registration,
         addressed to the underwriters, if any, and to the seller making such
         request, covering such legal matters with respect to the registration
         in respect of which such opinion is being given as such seller may
         reasonably request and are customarily included in such opinions;

                                    (xi) otherwise use its best efforts to
         comply with all applicable rules and regulations of the SEC, and make
         available to its security holders, as soon as reasonably practicable
         but no later than fifteen (15) months after the effective date of the
         registration statement, an earnings statement covering a period of
         twelve (12) months beginning after the effective date of the
         registration statement, in a manner which satisfies the provisions of
         Section 11(a) of the Securities Act and Rule 158 thereunder;

                                    (xii) cause all such Registrable Securities
         to be listed on each securities exchange on which similar securities
         issued by the Company are then listed, provided that the applicable
         listing requirements are satisfied;

                                    (xiii) keep Holders' Counsel advised in
         writing as to the initiation and progress of any registration under
         Section 3 or Section 4 hereunder;

                                    (xiv) cooperate with each seller of
         Registrable Securities and each underwriter participating in the
         disposition of such Registrable Securities and their respective counsel
         in connection with any filings required to be made with the National
         Association of Securities Dealers, Inc. (the "NASD"); and

                                       11

<PAGE>

                                    (xv) use best efforts to take all other
         steps necessary to effect the registration of the Registrable
         Securities contemplated hereby.

                           (b) Seller Information. The Company may require each
seller of Registrable Securities as to which any registration is being effected
to furnish to the Company such information regarding the distribution of such
securities as the Company may from time to time reasonably request in writing.

                           (c) Notice to Discontinue. Holder agrees that, upon
receipt of any notice from the Company of the happening of any event of the kind
described in Section 6(a)(vi), the Holder shall forthwith discontinue
disposition of Registrable Securities pursuant to the registration statement
covering such Registrable Securities until the Holder's receipt of the copies of
the supplemented or amended prospectus contemplated by Section 6(a)(vi) and, if
so directed by the Company, the Holder shall deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in such
Holder's possession, of the prospectus covering such Registrable Securities
which is current at the time of receipt of such notice. If the Company shall
give any such notice, the Company shall extend the period during which such
registration statement shall be maintained effective pursuant to this Agreement
(including, without limitation, the period referred to in Section 6(a)(ii)) by
the number of days during the period from and including the date of the giving
of such notice pursuant to Section 6(a)(vi) to and including the date when the
Holder shall have received the copies of the supplemented or amended prospectus
contemplated by and meeting the requirements of Section 6(a)(vi).

                           (d) Registration Expenses. The Company shall pay all
expenses (other than as set forth in Sections 3(d) and 4(b)) arising from or
incident to the performance of, or compliance with, this Agreement, including,
without limitation, (i) all SEC, stock exchange and NASD registration and filing
fees, (ii) all fees and expenses incurred in complying with securities or "blue
sky" laws (including reasonable fees, charges and disbursements of counsel in
connection with "blue sky" qualifications of the Registrable Securities), 
(iii) all printing, messenger and delivery expenses, (iv) the fees, charges and
disbursements of counsel to the Company and of its independent public
accountants and any other accounting fees, charges and expenses incurred by the
Company (including, without limitation, any expenses arising from any special
audits incident to or required by any registration or qualification) and any
legal fees, charges and expenses incurred by the Company and, in the case of a
Demand Registration, the Holder and (v) any liability insurance or other
premiums for insurance obtained in connection with any Demand Registration or
Incidental Registration pursuant to the terms of this Agreement, regardless of
whether such registration statement is declared effective. All of the
expenses described in this Section 6(d) are referred to herein as "REGISTRATION
EXPENSES."

                           (e) Information Blackout.

                                    (i) At any time when a Registration
         Statement effected pursuant to Section 3 relating to Registrable
         Securities is effective, upon written notice from the Company to Holder
         that the Company has determined in good faith that sale of Registrable
         Securities pursuant to the Registration Statement would require
         disclosure of non-public material information having an adverse effect
         on the Company (an "INFORMATION BLACKOUT"), Holder shall immediately
         suspend sales of Registrable Securities pursuant to such Registration
         Statement until the earlier of:

                                            (A) 60 days after the Company makes
                  such good faith determination, and

                                            (B) such time as the Company
                  notifies the Holder that such material information has been
                  disclosed to the public or has ceased to be material or that
                  sales pursuant to such Registration Statement may otherwise be
                  resumed (the number of days from such suspension of sales by
                  the Holder until the day when such sale may be resumed
                  hereunder is hereinafter called a "SALES BLACKOUT PERIOD").

                                    (ii) Any delivery by the Company of notice
         of an Information Blackout during the forty-five (45) days immediately
         following effectiveness of any Registration Statement effected pursuant
         to Section 3 above shall give the holders of a majority of the
         Registrable Securities being sold the right, by written notice to the
         Company within twenty (20) business days after the end of such
         Information Blackout, to cancel such registration, in which event
         Holder shall have one additional registration right under Section 3
         above ("BLACKOUT TERMINATION RIGHT").

                                    (iii) If there is an Information Blackout
         and the Blackout Termination Right, if any, pursuant to clause 
         (ii) above, is not available or exercised, the time period set forth
         in Section 6(a)(ii) shall be extended for a number of days equal to the
         number of days in the Sales Blackout Period.

                  7. Indemnification: Contribution.

                           (a) Indemnification by the Company. The Company
agrees to indemnify and hold harmless, to the fullest extent permitted by law,
each Holder, its officers, directors, trustees, partners, employees, advisors
and agents and each Person who controls (within the meaning of the Securities
Act or the Exchange Act) such Holder from and against any and all losses,
claims, damages, liabilities and expenses (including reasonable costs of
investigation) arising out of or based upon any untrue, or allegedly untrue,
statement of a material fact contained in any

                                       13

<PAGE>

registration statement, prospectus or preliminary prospectus or notification or
offering circular (as amended or supplemented if the Company shall have
furnished any amendments or supplements thereto) or arising out of or based upon
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading,
except insofar as the same are caused by or contained in any information
concerning such Holder furnished in writing to the Company by such Holder
expressly for use therein. The Company shall also provide customary indemnities
to any underwriters of the Registrable Securities, their officers, directors and
employees and each Person who controls such underwriters (within the meaning of
the Securities Act and the Exchange Act) to the same extent as provided above
with respect to the indemnification of the Holders of Registrable Securities.

                           (b) Indemnification by Holders. In connection with
any registration statement in which a Holder is participating pursuant to
Section 3 or Section 4 hereof, each such Holder shall furnish to the Company in
writing such information with respect to such Holder as the Company may
reasonably request or as may be required by law for use in connection with any
such registration statement or prospectus and each Holder agrees to indemnify
and hold harmless, to the fullest extent permitted by law, the Company, any
underwriter retained by the Company and their respective directors, officers,
employees and each Person who controls the Company or such (within the meaning
of the Securities Act and the Exchange Act) to the same extent as the foregoing
indemnity from the Company to the Holders set forth in Section 7(a) hereof, but
only with respect to any such information with respect to such Holder furnished
in writing to the Company by such Holder expressly for use therein; provided,
however, that the total amount to be indemnified by such Holder pursuant to this
Section 7(b) shall be limited to the net proceeds received by such Holder in the
offering to which the registration statement or prospectus relates.

                           (c) Conduct of Indemnification Proceedings. Any
Person entitled to indemnification hereunder (the "INDEMNIFIED PARTY") agrees to
give prompt written notice to the indemnifying party (the "INDEMNIFYING PARTY")
after the receipt by the Indemnified Party of any written notice of the
commencement of any action, suit, proceeding or investigation or threat thereof
made in writing for which the Indemnified Party intends to claim indemnification
or contribution pursuant to this Agreement; provided, however, that the failure
so to notify the Indemnifying Party shall not relieve the Indemnifying Party of
any liability that it may have to the Indemnified Party hereunder. If notice of
commencement of any such action is given to the Indemnifying Party as above
provided, the Indemnifying Party shall be entitled to participate in and, to the
extent it may wish, jointly with any other Indemnifying Party similarly
notified, to assume the defense of such action at its own expense, with counsel
chosen by it and satisfactory to such Indemnified Party. The Indemnified Party
shall have the right to employ separate counsel in any such action and
participate in the defense thereof, but the fees and

                                       14

<PAGE>

expenses of such counsel (other than reasonable costs of investigation) shall be
paid by the Indemnified Party unless (i) the Indemnifying Party agrees to pay
the same, (ii) the Indemnifying Party fails to assume the defense of such action
with counsel satisfactory to the Indemnified Party in its reasonable judgment or
(iii) the named parties to any such action (including any impleaded parties)
have been advised by such counsel that either (x) representation of such
Indemnified Party and the Indemnifying Party by the same counsel would be
inappropriate under applicable standards of professional conduct or (y) there
may be one or more legal defenses available to it which are different from or
additional to those available to the Indemnifying Party. In either of such
cases, the Indemnifying Party shall not have the right to assume the defense of
such action on behalf of such Indemnified Party. No Indemnifying Party shall be
liable for any settlement entered into without its written consent, which
consent shall not be unreasonably withheld.

                           (d) Contribution. If the indemnification provided for
in this Section 7 from the Indemnifying Party is unavailable to an Indemnified
Party hereunder in respect of any losses, claims, damages, liabilities or
expenses referred to therein, then the Indemnifying Party, in lieu of
indemnifying such Indemnified Party, shall contribute to the amount paid or
payable by such Indemnified Party as a result of such losses, claims, damages,
liabilities or expenses in such proportion as is appropriate to reflect the
relative fault of and benefits to the Indemnifying Party and Indemnified Party
in connection with the actions which resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative benefits to such Indemnifying Party and Indemnified Party shall be
deemed to be in the same respective proportions as the total proceeds from the
Public Offering received by such Indemnifying Party and Indemnified Party. The
relative faults of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action. The amount paid or payable by a party as a
result of the losses, claims, damages, liabilities and expenses referred to
above shall be deemed to include, subject to the limitations set forth in
Sections 7(a), 7(b) and 7(c), any legal or other fees, charges or expenses
reasonably incurred by such party in connection with any investigation or
proceeding, provided that the total amount to be indemnified by such Holder
shall be limited to the net proceeds received by such Holder in the offering.

                           The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 7(d) 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 immediately preceding
paragraph. No person

                                       15

<PAGE>

guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person.

                  8. Rule 144. The Company covenants that it shall file (a) any
reports required to be filed by it under the Exchange Act and (b) take such
further action as each Holder of Registrable Securities may reasonably request
(including providing any information necessary to comply with Rules 144 and 144A
under the Securities Act), all to the extent required from time to time to
enable such Holder to sell Registrable Securities without registration under the
Securities Act within the limitation of the exemptions provided by (i) Rule 144
under the Securities Act, as such rule may be amended from time to time, or 
(ii) any similar rules or regulations hereafter adopted by the SEC. The Company
shall, upon the request of any Holder of Registrable Securities, deliver to such
Holder a written statement as to whether it has complied with such requirements.

                  9. Miscellaneous.

                           (a) Recapitalizations, Exchanges, etc. The provisions
of this Agreement shall apply, to the full extent set forth herein with respect
to (i) the shares of Common Stock and (ii) any and all equity securities of the
Company or any successor or assign of the Company (whether by merger,
consolidation, sale of assets or otherwise) which may be issued in respect of,
in conversion of, in exchange for or in substitution of, the shares of Common
Stock and shall be appropriately adjusted for any stock dividends, splits,
reverse splits, combinations, recapitalizations and the like occurring after the
date hereof. The Company shall cause any successor or assign (whether by merger,
consolidation or otherwise) to enter into a new registration rights agreement
with the Holder on terms substantially similar to this Agreement as a condition
of any such transaction.

                           (b) No Inconsistent Agreements. The Company shall not
enter into any agreement with respect to its securities that is inconsistent
with the rights granted to the Holder in this Agreement or grant any additional
registration rights to any Person or with respect to any securities which are
not Registrable Securities which are prior in right to or inconsistent with the
rights granted in this Agreement.

                           (c) Remedies. The Holder, in addition to being
entitled to exercise all rights granted by law, including recovery of damages,
shall be entitled to specific performance of their rights under this Agreement.
The Company agrees that monetary damages would not be adequate compensation for
any loss incurred by reason of a breach by it of the provisions of this

<PAGE>
                                OPTION AGREEMENT


         THIS OPTION AGREEMENT is entered into as of September 4, 1996, by and
between Doctors Health System, Inc., a Maryland corporation (the "COMPANY"), and
Genesis Health Ventures, Inc., a Pennsylvania corporation ("GENESIS").

         WHEREAS, the Company and Genesis have entered into a Stock Purchase
Agreement (the "STOCK PURCHASE AGREEMENT") pursuant to which Genesis has agreed
to purchase 571,428 shares of the Company's Series C Preferred Stock, par value
$17.50 per share (the "SERIES C PREFERRED STOCK"); and

         WHEREAS, the Stock Purchase Agreement requires the parties to enter
into an Option Agreement in connection with the purchase by Genesis of
additional shares of Series C Preferred Stock.

         NOW, THEREFORE, in consideration of the foregoing, and the mutual
covenants and agreements hereinafter set forth, the parties hereby agree as
follows:


1.       OPTION TO PURCHASE SHARES

         Subject to the terms and conditions hereof, the Company hereby grants
to Genesis an option (the "Option") to purchase 500,000 shares (as adjusted
herein, the "SHARES") of the Series C Preferred Stock. The exercise price of the
Option shall be $20.00 per share, payable by wire transfer in United States
Dollars (the "OPTION PRICE"), for a total of $10,000,000. The Option shall be
immediately exercisable by Genesis at any time prior to its expiration. The
Option shall expire upon the earliest date on which one of the following occurs
(the "OPTION TERMINATION DATE"): (i) August 30, 2001; or (ii) the consummation
of (a) a Qualified Public Offering, (b) a merger or similar combination
transaction of which the Company is not the survivor, or (c) a sale or other
disposition of substantially all of the Company's assets (any of (a)-(c)
hereinafter referred to as a "QUALIFIED TRANSACTION"). The Company shall provide
Genesis with a written notice at least 30 days prior to the consummation of any
Qualified Transaction. For purposes of this Agreement, a QUALIFIED PUBLIC
OFFERING shall mean an offering of the Company's Common Stock registered under
the Securities Act with (a) the net proceeds to the Company of the sale of such
Common Stock to equal or exceed $25,000,000, (b) a total market capitalization
of the Company at the time of such offering of at least $100,000,000, (c) the
net price per share to equal or exceed the weighted average price paid by
Genesis for each share of Series C Preferred Stock outstanding immediately prior
to such offering, plus all accrued but unpaid dividends (whether declared or
undeclared) and interest thereon, as adjusted for stock splits,
recapitalizations and similar transactions, and (d) subject to a firm

<PAGE>

commitment underwriting conducted by a nationally recognized underwriter
reasonably acceptable to Genesis.


2.       ADJUSTMENT IN NUMBER OF OPTION SHARES AND/OR OPTION PRICE

         2.01. If the number of outstanding shares of Series C Preferred Stock
is increased or decreased or changed into or exchanged for a different number or
kind of stock or other securities of the Company by reason of any
recapitalization, reclassification (including any reclassification in connection
with a merger, consolidation or other business combination involving the
Company), stock split, reverse split, combination of shares of Series C
Preferred Stock, stock dividend or other distribution payable in capital stock,
or other increase or decrease in shares of Series C Preferred Stock effected
without receipt of consideration by the Company occurring after the date hereof,
a proportionate and appropriate adjustment shall be made by the Company in the
number and kind of shares subject to the Option, so that the proportionate
interest in the Company of Genesis immediately following such event shall, to
the extent practicable, be the same as immediately prior to such event. Any such
adjustment in the Option shall not change the aggregate Option Price with
respect to shares subject to the unexercised portion of the Option but shall
include a corresponding proportionate adjustment in the Option Price per share.

         2.02. If, after the date hereof but prior to the Option Termination
Date (the "ADJUSTMENT PERIOD"), the Company sells Series C Preferred Stock or
securities convertible into or exchangeable for Series C Preferred Stock, for a
price (the "LOWER OFFERING PRICE") less than the weighted average price paid or
to be paid by Genesis for each share of Series C Preferred Stock then
outstanding or subject to the Option, plus all accrued but unpaid dividends and
interest thereon (the "WEIGHTED AVERAGE PRICE"), the Option Price shall be
adjusted to a price equal to the quotient obtained by dividing:

                  (1) an amount equal to (x) the sum of (A) the total number of
         shares of Series C Preferred Stock outstanding immediately prior to
         such issuance or sale, plus (B) the total number of shares of Series C
         Preferred Stock issuable upon exercise of all options, warrants and
         other rights convertible or exchangeable for, or evidencing the right
         to purchase shares of Series C Preferred Stock outstanding immediately
         prior to such issuance or sale, if any, multiplied by (C) the Weighted
         Average Price in effect immediately prior to such issuance or sale,
         plus (y) the consideration, if any received or deemed to be received by
         the Company upon such issuance or sale; by

                  (2) the sum of (A) the total number of shares of Series C
         Preferred Stock outstanding immediately after such issuance or sale,
         plus (B) the total

                                       2

<PAGE>

         number of shares of Series C Preferred Stock issuable upon exercise of
         all options, warrants and other rights convertible or exchangeable for,
         or evidencing the right to purchase shares of Series C Preferred Stock
         outstanding immediately after such issuance or sale, if any.

         If, subsequent to such an adjustment, the Company issues or sells
additional shares of Series C Preferred Stock during the Adjustment Period, for
a price of less than the then applicable Weighted Average Price (as adjusted for
all prior adjustments), a further adjustment in the Option Price shall be made
in accordance with this Section 2.


3.       PARTIAL EXERCISE

         The Option shall be exercisable in whole or in part, at any time and
from time to time, after becoming exercisable and prior to termination of the
Option, provided, that no single exercise of the Option shall be for less than
10,000 Shares unless the number of Shares purchased is the total number at the
time available for purchase under this Option. In no event may the Option be
exercised for a fractional Share. The number of shares which may be purchased
upon exercise of the Option shall be reduced by the number of shares previously
purchased upon exercise of the Option.


4.       METHOD OF EXERCISE OF OPTION

         Subject to the terms and conditions of this Option Agreement, Genesis
may exercise the Option with respect to all or any part of the Shares then
subject to such Option by giving the Company written notice of exercise,
specifying the number of Shares as to which the Option is being exercised. Such
notice shall be addressed to the Secretary of the Company at the Company's
principal office, and shall be effective upon delivery (by personal delivery,
fax or other delivery) to the Secretary of the Company. Such notice shall be
accompanied by cash (in U.S. Dollars) in an amount equal to the Option Price of
such Shares. The Company's obligations to issue Shares pursuant to this
Agreement are subject to the expiration, prior to an exercise of the Option, of
any waiting period applicable to the investment by Genesis in the Company
required by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended.

5.       MANDATORY EXERCISE

         5.01. FIRST MANDATORY EXERCISE. Subject to the conditions set forth in
Sections 5.03 and 5.04, the Company may require Genesis to exercise the Option
with respect to such number of Shares as the Company shall determine in an
amount no greater than one-half the number of Shares for which the Option may be
exercised at the end of any month which is the second consecutive month during

                                       3

<PAGE>

which the Company has received payment for a total of at least 20,000 Capitated
Medicare Lives.

         5.02. SECOND MANDATORY EXERCISE. Subject to the conditions set forth in
Sections 5.03 and 5.04, Genesis may be required by the Company to exercise the
Option with respect to any Shares for which the Option has not yet been
exercised at the end of any month which is the second consecutive month during
which the Company has received payment for a total of at least 40,000 Capitated
Medicare Lives.

         5.03. The obligations of Genesis to exercise the Option pursuant to
this Section 5 are subject to the fulfillment on or before each such exercise of
each of the following conditions:

         attached as Exhibit A hereto dated as of the date of such exercise.

                  5.03(B) The Company shall have performed and complied with all
         material agreements, obligations and conditions contained in the Stock
         Purchase Agreement and the Restated Stockholders Agreement dated as of
         the date hereof.

                  5.03(C) All consents, authorizations, approvals or permits, if
         any, of any governmental authority or regulatory body of the United
         States or of any state or of any third party that are necessary in
         connection with the exercise of the Option and the lawful issuance of
         the Shares to Genesis pursuant to this Option Agreement shall have been
         duly obtained and shall be effective on and as of such exercise other
         than those which are not required to be obtained before such exercise.

                  5.03(D) There shall not have been any default or breach by the
         Company (that has not been cured or waived) with respect to its
         obligations (i) to holders of the Company's Series A Preferred Stock,
         Series B Preferred Stock and Series C Preferred Stock under the
         Company's articles of incorporation, (ii) to NationsBank, N.A. under
         the Loan Agreement dated as of December 1, 1995 and (iii) to First
         National Bank of Maryland, N.A. under the Promissory Note dated as of
         August 15, 1996 or under any successor credit facility, including,
         without limitation, the facility currently being negotiated with First
         National Bank of Maryland, N.A.

                  5.03(E) The expiration of any waiting period applicable to the
         investment by Genesis in the Company required by the Hart-Scott-Rodino
         Antitrust Improvements Act of 1976, as amended.

         5.04 The Company shall provide Genesis with a written notice at least
30 days prior to a mandatory exercise pursuant to this Section 5. Such notice
shall set

                                       4

<PAGE>

forth the number of Shares for which Genesis will be required to exercise the
Option, which number will not be less than 10,000 Shares.

         5.05. For purposes of this Section 5, the term "CAPITATED MEDICARE
LIVES" shall mean those Medicare-eligible persons living in Maryland, Delaware,
West Virginia and the District of Columbia and in the areas of Northern Virginia
and Southern Pennsylvania who, at the time of any calculation under this Section
5, are enrolled in (a) a "Medicare HMO" or similar Medicare managed care product
offered directly by the Company under contract with the United States Health
Care Financing Administration ("HCFA") and with respect to whom the Company
receives a capitation or other risk-based payment from HCFA, or (b) a "Medicare
HMO" or other similar Medicare managed care product offered by a health
maintenance organization or other payor with respect to which the Company agrees
to provide or arrange to provide all or substantially all of those services now
qualifying as "Medicare Part A" and "Medicare Part B" benefits under
arrangements that permit the Company to realize all or the preponderance of any
savings obtained by managing the provision of such services to enrolled Medicare
members.


6.       LIMITATIONS ON TRANSFER

         The Option is not transferable by Genesis, other than to a corporation
that, directly or indirectly, is wholly owned by Genesis, and shall not be
pledged or hypothecated (by operation of law or otherwise) or subject to
execution, attachment or similar processes.

7.       RESERVATION OF STOCK

         The Company shall at all times reserve and keep available, solely for
issuance and delivery upon exercise of the Option, the number of shares of
Series C Preferred Stock from time to time issuable upon exercise of the Option.
All shares of Series C Preferred Stock issuable upon exercise of the Option
shall be duly authorized and, when issued upon exercise and the payment of the
Option Price as provided herein, shall be validly issued, fully paid and
nonassessable with no liability on the part of Genesis.

8.       RIGHTS AS SHAREHOLDER

         Neither Genesis nor any successor or permitted assign shall be, or have
any of the rights or privileges of, a shareholder of the Company in respect of
any Shares issuable hereunder unless and until such Shares have been fully paid
and certificates representing such Shares have been endorsed, transferred and
delivered, and the name of Genesis (or of such successor or permitted assign)
has been entered as the shareholder of record on the books of the Company.

9.       REORGANIZATIONS

         9.1 REORGANIZATION IN WHICH THE COMPANY IS THE SURVIVING ENTITY.
Subject to Section 9.2, if the Company shall be the surviving entity in any
reorganization, merger or consolidation of the Company with one or more other
entities, the Option shall pertain to and apply to the securities to which a
holder of the number of Shares subject to the Option would have been entitled
immediately following such reorganization, merger or consolidation, with a
corresponding proportionate adjustment of the Option Price per share so that the
aggregate Option Price thereafter shall be the same as the aggregate Option
Price of the Shares remaining subject to the Option immediately prior to such
reorganization, merger or consolidation.

         9.2 REORGANIZATION IN WHICH THE COMPANY IS NOT THE SURVIVING
CORPORATION OR SALE OF ASSETS. Upon the dissolution or liquidation of the
Company, or upon a merger, consolidation or reorganization of the Company with
one or more other entities in which the Company is not the surviving entity, or
upon a sale of all or substantially all of the assets of the Company to another
entity, or upon any transaction (including, without limitation, a merger or
reorganization in which the Company is the surviving entity) approved by the
Board of Directors of the Company which results in any person or entity, or
persons or entities acting as a group or otherwise in concert owning 50 percent
or more of the combined voting power of all classes of stock of the Company, the
Option hereunder shall terminate, except to the extent provision is made in
writing in connection with such transaction for the continuation and/or the
assumption of the Option, or for the substitution for the Option of new options
covering the stock of a successor corporation, or a parent or subsidiary
thereof, with appropriate adjustments as to the number and kinds of shares of
stock and exercise prices, in which event the Option shall continue in the
manner and under the terms so provided. The Company shall send written notice of
an event that will result in such a termination to Genesis not later than the
time at which the Company gives notice thereof to its shareholders but in no
event less than 30 days prior to such event.

10.      ADJUSTMENTS

         No fractional shares or units of other securities shall be issued
pursuant to any such adjustment, and any fractions resulting from any such
adjustment shall be eliminated in each case by rounding downward to the nearest
whole share or unit. Any disputes regarding adjustments in the Option Price or
number of Shares issuable upon exercise of the Option (including without
limitation any adjustments pursuant to Section 2 hereof) shall be resolved by an
independent arbitrator selected by the Company and Genesis.

defined as an area within a radius of thirty (30)  minutes  travel time from the
location  of each IPA Health  Center or Primary  Care  Physician's  office.  The
purpose of the service area  designation  will be for the  determination  of the

Medical Services. IPA acknowledges that the Member shall have the absolute right
to select  his/her  provider of medical  services,  and that this  service  area
designation  is for  purposes of  guidance  only and does not entitle IPA to the

the HMO and the IPA to the Department and HCFA for the provision of services and
benefits  to MA &  Medicare  Members,  as  provided  for in the MA and  Medicare
Contracts.

                  2.2.2 None of the  provisions of this Agreement is intended to
create nor shall be deemed nor construed to create any relationship  between IPA
and HMO other  than that of  independent  entities  contracting  with each other
solely for effecting the  provisions of this  Agreement.  Neither of the parties

agent, employer, or representatives of the other.

         2.3  Indemnification.  IPA shall  indemnify and hold HMO, its employees
and  agents,  harmless  from  any and all  claims,  lawsuits,  settlements,  and
liabilities incurred as a result of the services provided or not provided by IPA

shall  indemnify  and  hold IPA  harmless  from  any and all  claims,  lawsuits,
settlements,  and liabilities incurred as a result of actions taken or not taken
by HMO in the administration of the Covered Services under this Agreement.

         2.4 Cooperation. IPA and HMO shall maintain effective liaison and close

with generally accepted accounting principles, consistently applied.

         2.6  Proprietary  Information.  IPA and HMO  each  recognize  that  all
material provided to each by the other party is the proprietary  property of the
party providing the information and neither party shall disclose or release such
material  to any third  party  without  the prior  written  consent of the party
providing the  information,  except as otherwise  required by law or regulation.
Upon  termination  or expiration of this  Agreement,  each party shall  promptly
return  all  such  proprietary   information  to  the  party  who  provided  the
information.

         2.7 Confidential.  IPA and HMO shall use their best efforts to preserve
the  confidentiality  of the pricing  terms  contained in this  Agreement.  Both
parties acknowledge that all information  obtained from the other in negotiating
and completing the transaction  contemplated  therein is strictly  confidential.

                           ARTICLE III - COMPENSATION

         3.1      IPA Capitation Payment.

                  3.1.1  Subject  to the  provisions  of Section  3.2  regarding
withholds,  the HMO will pay to the IPA a monthly  capitation  payment  for each
Non-MA Member selecting the IPA as set forth in Attachment G, for each MA Member
as set  forth in  Attachment  H and for each  Medicare  Member  as set  forth in
Attachment 1.

                  3.1.2 The capitation payment shall be made on the tenth (10th)
day of each month,  or on the next business day if the tenth (10th) is a weekend
day or legal holiday.

                  3.1.3 IPA agrees to accept  from the HMO the  mutually  agreed
upon  monthly  capitation  payments set forth in  Attachment  G (for  Commercial
Members),  Attachment H (for MA Members) and Attachment I (for Medicare Members)
as payment in full for all  Covered  Medical  Services  to be  provided  by IPA,
except for any authorized  copayments.  HMO and IPA mutually agree to adjust the
capitations  set  forth in  Attachments  G, H,  and I, in the  event  that  said
services and/or premiums are materially  increased,  reduced, or changed. If the
parties are unable to agree on the amount of such adjustments,  either party may
terminate this Agreement upon ninety (90) days prior written notice,  subject to
provisions contained in Section 6.3.2.

                  3.1.4  Capitation  rates  for  Members  who  select  IPA for a
fraction of a month will be as follows:  for Members enrolling between the first
(1st) and fifteenth  (15th) day of the month, IPA will be capitated for the full
month.  For Members  enrolling  between the sixteenth  (16th) and the end of the
month,  capitation  payments and IPA service  obligations for said Members shall
begin on the first day of the following month.

                  3.1.5  Capitation  rates for  Members who  disenroll  from IPA
during a month will be as follows:  for Members who disenroll  between the first
(1st) and fifteenth (15th) day of the month, IPA will not receive any capitation
payments.  For Members who disenroll between the sixteenth (16th) day to the end
of the month,  IPA will receive a  capitation  payment on behalf of such Members
for the full month.

                  3.1.6 The HMO shall produce  and/or make  available to the IPA
by the fifteenth day of each month a listing of the following:

                           (a)      Members who have chosen the IPA as provider
of care, and whose membership is effective during the month following the month
in which the listing is provided to IPA;

                           (b)      Members whose enrollment was effective prior
to the first day of the following month and whose enrollment was not reported on
previous listings;

                           (c)      Members who are enrolled as of the date of
the listing and whose enrollment is to be terminated; and

                           (d)      Any corrections or adjustments to prior
months listings.

                  3.1.7 IPA, in consideration of said capitation payments, shall
provide  or  arrange  for all  those  physician  services  as  required  in this
Agreement and shall assume the responsibility for the costs of said services, as
specifically defined in the Subscription Agreement.  Regardless of the number of
External  Providers  rendering  service to a Member  during any month,  only one
capitation  payment  will  be  made to IPA  each  month  for  each  Member.  The
capitation  payment  shall be made  regardless  of the type or amount of service
rendered to the Member  during a given month.  Although  services not covered by
the  Member's  agreement  with the HMO may be provided by the IPA, the HMO shall
have no  responsibility  to pay for benefits  not  included in the  Subscription
Agreement and applicable benefit riders.

         3.2  Reserve.   Pursuant  to  Maryland  Health-General  19-713.2,  upon
contract signature IPA shall provide HMO with reasonably  acceptable  collateral
to secure an amount equal to the  immediately  preceding  sixty (60) days of IPA
capitation.  The purpose of such Reserve is to ensure that sufficient  funds are
on hand to reimburse HMO for any payment made to External Providers, as required
by law, if IPA fails to make any such payments. HMO agrees that a Standby Letter
of  Credit  from  a  commercial  bank  shall  be  deemed  reasonably  acceptable
collateral for such  purposes.  Such Standby Letter of Credit shall be delivered
upon such standard  commercial terms and conditions as the Bank, HMO and IPA may
agree.

         3.3 Ineligible for Coverage.  In the event an individual ceases to be a
Member or becomes  ineligible for HMO coverage while receiving Covered Services,
HMO shall promptly notify IPA of such  ineligibility.  Neither IPA nor HMO shall
be responsible  for the cost of any Covered  Services  rendered to an individual
after that  individual  has ceased to be a Member.  IPA may bill the  individual
directly for any such services provided to a person who is not a Member.

         3.4  Retroactive  Adjustments.  Any  errors in the  calculation  of the
number of Members  resulting from  termination or  miscalculation  of membership
will be  retroactively  adjusted  by HMO for a period not to exceed 90 days from
the date the error  occurred.  Notwithstanding  such time period,  HMO shall use
best efforts to adjust any miscalculation of the number of Members within thirty
(30) days following the date that a Capitation Fee payment is made. Any mistakes
not adjusted within such thirty (30) day period, however, shall be adjusted when
discovered;  provided,  however,  that no  overpayments to IPA shall be adjusted
more than ninety (90) days after such payment is made.  In the event that,  as a
result of the failure of HMO to use such best efforts, an underpayment to IPA is
not  adjusted  within the ninety (90) day  period,  such  underpayment  shall be
adjusted when discovered.

         3.5 Non-Covered  Services. In the event a Member desires services which
are beyond the scope or duration of Covered  Services under this Agreement,  IPA
shall verify with HMO that HMO has no obligation  to provide  those  non-covered
services and, if such verification is obtained, IPA shall inform the Member that
such services are not Covered  Services and  thereafter  may bill the Member for
such Non-Covered Services.

         3.6      External Providers.

                  3.6.1 IPA shall promptly and fully pay all External  Providers
who provide Medical  Services to Members which were arranged or referred by IPA,
in accordance  with the terms of its  applicable  understandings,  contracts and
agreements,  and as required  by law and which are also  Covered  Services.  IPA
shall pay an External Provider  providing  services to all Members no later than
thirty (30) days after  receipt of a complete and  undisputed  claim for Medical
Services, unless a longer period of time has been agreed to by HMO.

                  3.6.2 HMO shall have the right to contact  External  Providers
directly to verify whether IPA is current in its payment to them. As required by
Section  5.8  below,  IPA must  certify  to HMO on a  quarterly  basis as to its
payments to External Providers.

assurance programs.

         4.4 Collections of Premiums and Other Income. HMO agrees to collect all
premiums  and other items of income to which the HMO is entitled  except for any
copayments,  coinsurance, or deductibles which may be required of Members at the
time of service.  Such copayments,  coinsurance or deductibles,  if any, will be
collected by IPA's External Providers when Covered Services requiring copayments
are rendered.  HMO will develop reasonable policies regarding the termination of
enrollment of Members who fail to make copayments.

         4.5 Staff  Assistance.  HMO shall  appoint a Medical  Director who will
provide continued staff assistance to IPA. This assistance shall include but not
be limited to advising on the development  of: referral  protocols for Physician

applicable  confidentiality  requirements to ensure that appropriate information

for  referrals  to  Referral  Physicians;   and  length-of-stay   determination,
pre-admission  testing,  and other  criteria  necessary to authorize and approve
inpatient admissions prior to hospitalization.

         4.6      HMO's Professional Liability Insurance.  HMO, at its sole cost
and expense, shall procure and maintain such policies of general liability and
professional liability insurance and other insurance as shall be necessary to
insure HMO and its employees against any claim occasioned directly, or
indirectly, in connection with the performance of any service by HMO, the use of
any property, facilities or equipment provided by HMO, and the activities
performed by HMO in connection with this Agreement.  Said insurance limits shall
not be less than ($1,000,000) individual and ($3,000,000) aggregate.

                        ARTICLE V - IPA RESPONSIBILITIES

         5.1 Medical  Services.  IPA agrees to provide  those  Covered  Services
which are Medical  Services and are set forth in  Attachments  B, C, & D to each
Member who selects IPA as his/her provider of care. For MA and Medicare Members,
IPA also  agrees to  provide  those  services  required  by the  current  MA and
Medicare  Contracts  which IPA has the capacity to provide.  Any other  services
require the prior  written  consent of IPA. A copy of the  current  Subscription
Agreements and supplemental  benefit riders are provided as Attachment E and may
be revised by HMO from time to time as changes are  required.  HMO shall provide
IPA with  ninety  (90) days prior  written  notice of any  modifications  to the
Subscription  Agreement  or the MA  and  Medicare  Contracts  provided  that  no
modification that changes IPA's  responsibilities  or otherwise  increases IPA's
financial risk hereunder shall become  effective  unless consented to in writing
by IPA.

         5.2 Referral  Physician  Services.  In  consideration of the capitation

HMO is required to provide as Covered  Services and which are Medical  Services.
IPA agrees to identify and arrange with Referral  Physicians  and other referral
health  professionals who are duly licensed in a manner designed to implement an
efficient system of referrals and consultations,  to facilitate the coordination
of medical services,  to ensure continuity of care, and to provide accessibility

Medical  Services,  IPA shall  enter  into a  written  agreement  with  Referral

necessity,   External   Providers  shall  agree  to  use  only  those  inpatient
facilities,   skilled  nursing  facilities,  home  health  agencies,  and  other
institutional providers which are Participating Providers, or have been approved
by HMO. HMO  delegates  credentialling  of these  providers to IPA, but reserves
right to disallow a specific provider due to quality of care criteria.  However,
the parties  agree that unless  services  are not  available  or  accessible  to
Members,  Members will be required to secure  Covered  Services  only from those
Participating  Providers  to  whom  a  referral  is  made  by the  Primary  Care
Physician.

         5.4      Standard of Medical Care.

                  5.4.1 IPA agrees to use its best efforts in rendering  Medical
Services in order to provide  medical care in conformity  with accepted  medical
and surgical practices  prevailing in the community,  and to arrange for medical
treatment as promptly as practicable,  consistent  with sound medical  practice.
Further,  the IPA agrees to establish  mechanisms  to: provide for internal peer
review of Members  records;  evaluate  the  quality of health  care  provided to
Members;  and evaluate the  utilization of Medical  Services  rendered by IPA to
Members.  Such  mechanisms  shall be in conformance  with  applicable  state and
federal requirements and the requirements set forth in the Provider Manual.

                  5.4.2  IPA and  all of  their  External  Providers  shall  not
differentiate  or  discriminate in the treatment of Members as to the quality of
services  delivered  because of race, sex, age,  religion,  national origin,  or
health status.  The rights of Members as patients  shall be observed,  protected
and  promoted.  Health  care  services  shall be rendered to Members in the same
manner,  in  accordance  with  the  same  standards,  and  with  the  same  time
availability as offered to all other patients.

                  5.4.3 Transportation  Expenses.   IPA shall be responsible for
the arrangement of and costs associated  with: (1) all ambulance  transportation
preauthorized by IPA for the provision of Medical Services,  (2)  transportation

radius from the Member's  place of residence,  excluding  Member's  Primary Care
Physician.

         5.5  Selection of IPA Primary  Care  Physician  or Health  Center.  IPA
agrees  that each  Member  seeking  care shall be  required to select a specific
Primary  Care  Physician  or Health  Center as his/her  personal  physician  for
providing and/or  arranging for his or her overall health care needs.  Except in
cases of Emergency,  referrals to referral health  professionals and obtaining a
Medical  Service from any other  provider,  shall only be a Covered Service when
authorized by the Member's Primary Care Physician. Except in cases of Emergency,
referrals to Referral Physicians or other referral health  professionals and the
obtaining of a Medical  Service from any other  provider shall only be a Covered
Service when  authorized by the Member's  Primary Care  Physician.  Except in an
Emergency,  IPA shall not be  responsible  for any Medical  Service  that is not
authorized by a Member's Primary Care Physician.

         5.6 Designated Physician to Authorize Referral and Hospitalization. IPA
agrees to designate a Physician, who shall be on call 24 hours per day, each and
every day, to authorize  appropriate  hospital  services or other  referrals for
Members.  IPA agrees to ensure that one or more Health  Centers or Primary  Care
Physicians  within the IPA service  area shall be  available  to Members who may
require  emergency  care. HMO and IPA shall,  from time to time,  jointly review
methods and details of coverage  and  scheduling  to ensure  adequate  emergency
coverage  and  adequate  medical  coverage  at the  Health  Centers  or  Primary
Physician's  offices at all times the facilities  and/or  physician  offices are
open.

         5.7  Coordination  of  Benefits  and  Subrogation.  IPA and  HMO  shall
establish and implement a system for  coordination of benefits and  subrogation,
in  accordance  with  those  rules  established  under  the HMO's  policies  and
procedures  and  applicable  federal and state laws.  If known to IPA, IPA shall
identify  and  inform HMO of  Members  for whom  coordination  of  benefits  and
subrogation opportunities exist. HMO hereby authorizes IPA to seek payment, on a
fee-for service basis or otherwise, from any insurance carrier, organization, or
government agency which is primarily responsible for the payment or provision of
medical services  provided by IPA under this Agreement which can be recovered by
reason of coordination of benefits, motor vehicle injury, worker's compensation,
temporary disability,  occupational disease, or similar exclusionary or limiting
provisions,  to the  extent  authorized  by the  applicable  and  not  otherwise
prohibited by law.

         5.8      Reporting Requirements.

reimbursement from or have any recourse against any Member, or any person (other

External Providers pursuant to their contracts with IPA; provided, however, that
External  Providers  may  collect  from  Members  any  approved  and  applicable
copayments or  supplemental  charges or charges for non-Covered  Services.  Each
such agreement must provide that this provision will survive the  termination of
the agreement, regardless of the cause of the termination.

                  5.9.6 In the event a Member desires  services which are beyond
the scope or  duration  of  Covered  Services  under  this  Agreement,  External

agreement, regardless of the cause of the termination.

circumstances,  including  non-payment  of  moneys  owed  to  the  IPA  by  HMO,

against  any  Member,  or any person  (other  than HMO)  acting on the  Member's
behalf,  for  Covered  Services  provided  by IPA  pursuant  to this  Agreement;
provided,  however,  that  IPA may  collect  from  the  Members  any  applicable
copayments  or  supplemental  charges or charges  for  non-Covered  Services  in

provided  to HMO  enrollees,  HMO shall  have the right to make  these  payments
directly  to the  subcontractor  provider  and to recover  from the IPA the full
amount of any such payments as outlined  under Section 3.2. In order to exercise

credentialling and selection of its External Providers, and facilities using the
standards  developed by the National Committee for Quality Assurance ("NCQA") as

                        Capitation For Medicare Members


At this time, this Agreement applies only to Medicare Members. At such time when
Medical  Assistance and/or Commercial  Members are added to this Agreement,  the
Agreement  will be  amended  to  reflect  the  rates  and any  additional  terms
applicable to this population.

HMO shall pay a capitation  amount for Medicare  Members who have agreed to have
IPA as their provider of care for such month.  In exchange for such  capitation,
IPA shall provide, arrange or purchase, or otherwise make available as Medically
Necessary,  the full scope of services to which  persons are entitled  under the
current  HMO  Medicare  Risk  Contract,  as may be  amended  from  time to time,
including   all   applicable   state  and   federal   regulations,   guidelines,
transmittals,  and  procedures,  except those services  carved out herein.  If a
Member requires a particular type of provider who is not in the IPA network, the
IPA is responsible for securing the provider and is financially liable.

1. On or before  the tenth  (10th)  day of each  month,  HMO will pay to IPA the
capitation  payment set forth in this Attachment for each Member who is enrolled
for that month in the respective benefit plan as set forth in this Attachment.

2. HMO will pay a capitation  rate to DHS on a per member per month basis on the
age,  sex and  Medicaid  eligibility  of the  subscribers  enrolled  with an IPA
Primary  Care  Physician in HMO's  Advantage  65 Medicare  HMO Program.  The IPA
capitation schedule is defined in this Attachment.  This schedule represents the
amount  of  capitation  IPA will  receive  AFTER  carve  out  dollars  have been
deducted.

3. The  payment  rates  defined  in this  Attachment  have been  derived  from a
mutually agreed upon formula which is based on HCFA's AAPCC payment methodology.
In the event that AAPCC  methodology is changed or discontinued by HCFA, HMO may
propose  alternative  pricing to IPA during the term of this  Agreement.  In the
event  that  IPA does not  accept  revised  payment  rates or  terms,  it may be
considered cause for early termination of this Agreement.

4. The capitation rates to IPA will increase, as defined in this Attachment when
IPA's  enrollment  of NEW HMO  Members  reaches  enrollment  thresholds  of
[Confidential Treatment Requested] Members, and again at [Confidential Treatment
Requested] Members.

5. IPA capitation rates in this Attachment reflect a deduction by HMO to pay for
"carve-outs".  The  carved-out  dollars  will  cover  all costs  related  to the
following  services  and IPA will have no  further  responsibility.  Changes  to
carve-outs costs may be made annually,  on the anniversary of the contract term,
and with the mutual  consent of both  parties.  The net premium is total premium
net of the carve outs which are listed below:

         CHP staff or a CHP  provider.  Complaints  can be filed  verbally or in
         writing and are processed by the Member Service Department.

         If a Medical  Assistance-HMO  member disenrolls from the HMO and states
         on the  disenrollment  form that  she/he  is  disenrolling  because  of
         alleged fraudulent marketing conduct, CHP must document this and pursue
         it as a complaint.

C.       A grievance is defined as a member's complaint regarding a previous
         issue that was not resolved to the member's satisfaction. A grievance
         is a member's request for reconsideration.  Grievances must be
         submitted in writing and are processed by the CHP Grievance Coordinator
         and Grievance Committee.

PROCEDURE:

To file a  complaint,  CHP  members  are  instructed  to contact  the CHP Member
Services Department and speak with a Member Services Representative.

The Member Service  Representative  is responsible  for researching the case and
working with appropriate CHP department(s) to resolve the member's issue. Member
Service Representatives attempt to resolve member issues upon the first contact.
Members must be informed of a resolution to their complaint or provided a status
report regarding their complaint within thirty (30) calendar days.
Medical  Assistance-HMO  members  must be provided  with a written copy of their
complaint.

Complaints  which  pertain to  emergency  situations  and  require an  expedited
determination are handled accordingly.

The Member Services Representative informs the member of his/her right to file a
grievance if she/he is not  satisfied  with the  resolution.  The member is also
informed of his/her right to appear before the Grievance Committee.

The member is instructed to direct his/her grievance to the attention of the CHP
Grievance Coordinator. Grievances must be submitted in writing within sixty (60)
days  after the  member  receives  notification  of the  resolution  of  his/her
complaint.

The Grievance  Coordinator is responsible for acknowledging,  in writing, to the
member receipt of his/her grievance within five (5) working days.

The  Grievance  Coordinator  will submit all  pertinent  documentation  to CHP's
Grievance Committee, which consists of the following CHP staff:

Vice President, Services
Vice President, Medical Services
Vice President, Operations
Director, Compliance

Grievances are resolved and the member is notified of the  committee's  decision
within thirty (30) days of receipt of the member's complete information.

The Grievance Committee is the final level of review within the Health Plan.

The  member is  advised  of  his/her  right to  contact  the  appropriate  state
government  regulatory agency if she/he is dissatisfied with the decision of the
Grievance  Committee.  The Grievance  Coordinator supports the activities of the
agency and the member during this review process.

stay of  execution,  or  supplementary  proceedings,  or other  relief  from the
enforcement or immediate  enforcement of a judgment or related  proceedings on a
judgment.  (Any judgment  obtained by confession  shall not constitute a lien on
any real property located in Pennsylvania which is the residence of any Borrower
if this Promissory Note is in the original principal amount of $50,000 or less.)
The authority and power to appear for and enter judgment  against Borrower shall
not be exhausted by one or more exercises thereof,  or by any imperfect exercise

expenses) and all other expenses resulting from such referral.

deemed to be a negotiable  instrument,  even though this Promissory Note may not
qualify under applicable law, absent this paragraph, as a negotiable instrument.

indorser,  or  guarantor,  waive  presentment,  demand,  notice of  dishonor and
protest.

enforceable  by Bank and Bank's  successors  and assigns and any other person to
whom Bank may grant an interest in Borrower's  obligations to Bank, and shall be
binding   and   enforceable    against   Borrower   and   Borrower's    personal
representatives, successors and assigns.

18.  VALIDITY OF ANY PART.  If any  provision  or part of any  provision of this
Promissory Note shall for any reason be held invalid,  illegal or  unenforceable
in any respect, such invalidity, illegality or unenforceability shall not affect
any other  provisions of this Promissory Note, and this Promissory Note shall be
construed as if such invalid, illegal or unenforceable provision or part thereof
had never  been  contained  herein,  but only to the  extent of its  invalidity,
illegality or unenforceability.

19. MAXIMUM RATE OF INTEREST;  COMMERCIAL LOAN. Notwithstanding any provision of
this  Promissory  Note to the contrary,  Borrower  shall not be obligated to pay
interest  hereunder in excess of the maximum  rate of interest  permitted by the
laws of any state  determined to govern this  Promissory Note or the laws of the
United  States  applicable  to loans in such  state.  If any  provision  of this
Promissory  Note shall ever be construed to require the payment of any amount of
interest in excess of that permitted by applicable  law, then the interest to be
paid  hereunder  shall be held subject to reduction to the amount  allowed under
applicable  law, and any sums paid in excess of the interest rate allowed by law
shall be applied in reduction of the principal  balance  outstanding  under this
Promissory  Note.  Borrower  acknowledges  that it has been  contemplated at all
times by Borrower that the laws of the State of Maryland will govern the maximum
rate of interest that it is permissible  for the holder of this  Promissory Note

Promissory  Note  evidences a loan made solely to acquire or carry on a business
or commercial enterprise.

be governed,  construed and interpreted in accordance with the laws of the State
of  Maryland,  even if the  Maryland  rules  governing  conflicts  of laws would
otherwise require that the laws of another  jurisdiction  govern this Promissory
Note.  Borrower  consents  to the  jurisdiction  and venue of the  courts of any
county in the State of Maryland or the courts of Baltimore City, Maryland and to
the  jurisdiction and venue of the United States District Court for the District
of Maryland in any action or judicial proceeding brought to enforce, construe or
interpret this Promissory Note.

21. UNCONDITIONAL OBLIGATIONS. Borrower's obligations under this Promissory Note
shall be the absolute and  unconditional  duties and obligations of Borrower and
shall be independent of any rights of set-off,  recoupment or counterclaim which
Borrower might  otherwise have against the holder of this  Promissory  Note, and
Borrower shall pay absolutely the payments of principal, interest, fees, charges
and expenses required  hereunder,  free of any deductions and without abatement,
diminution or set-off.

22. ACTIONS  AGAINST BANK. Any action brought by Borrower  against Bank which is
based, directly or indirectly, or in whole or in part, upon this Promissory Note
or any matter  related  to this  Promissory  Note  shall be brought  only in the
courts of the State of Maryland.

23. WAIVER OF JURY TRIAL.  Borrower (by execution of this  Promissory  Note) and
Bank (by acceptance of this  Promissory  Note) agree that any suit,  action,  or
proceeding, whether claim or counterclaim,  brought or instituted by Borrower or
Bank on or with  respect to this  Promissory  Note or which in any way  relates,
directly  or  indirectly,  to the  obligations  of  Borrower  to Bank under this
Promissory Note, or the dealings of the parties with respect  thereto,  shall be
tried  only by a court and not by a jury.  Borrower  and Bank  hereby  expressly
waive  any right to a trial by jury in any such  suit,  action,  or  proceeding.
Borrower and Bank  acknowledge  and agree that this  provision is a specific and
material  aspect of the  agreement  between  the parties and that Bank would not
enter into the  transaction  with Borrower if this  provision were not a part of
their agreement.

DOCTORS HEALTH SYSTEM, INC.
10451 Mill Run Circle, 10th Floor
Owings Mills, MD 21117

Gentlemen:

         St.  Joseph  Medical  Center,  Inc.  ("SJMC") is pleased to confirm its
intention,  upon the terms and  conditions  set forth herein,  to provide credit
enhancement  in  connection  with  loans in a  principal  amount  not  exceeding
$1,500,000  to  Doctors'  Health  System  ("DHS")  from First  National  Bank of
Maryland  ("Lender").  This  letter  shall set  forth  the terms and  conditions
thereof  and,  upon your  acceptance  of the terms  hereof as  evidenced by your
execution in the space set forth  below,  shall  constitute a binding  agreement
between DHS and SJMC.

         1.  SJMC  agrees  to  deliver  to  Lender  its  written  guaranty  (the
"Guaranty"),  in such form as shall be required by Lender and  approved by SJMC.
Pursuant  thereto,  SJMC shall  unconditionally  guarantee and be liable for the
payment  obligations of DHS in respect of loans advanced by Lender in accordance
with  its  Business  Purpose   Promissory  Note  dated  of  even  date  herewith
(collectively,  the "Guaranteed Obligations");  provided that the maximum amount
of the Guaranteed  Obligations shall not exceed  $1,500,000.  The Guaranty shall
terminate  not  earlier  than 60 days  following  the  incurrence  by DHS of the
Guaranteed  Obligations  (or,  if not  advanced  in full by Lender,  the initial
advance of proceeds thereof by Lender in connection therewith).

         2. Any  advance  made by SJMC to  Lender in  connection  with any claim
under the  Guaranty  shall be deemed to  constitute  a loan (each a "Loan") from
SJMC to DHS,  which Loan shall be  immediately  due and  payable by DHS to SJMC.
Each Loan  shall  bear  interest  at a rate equal to 5% in excess of the rate of
interest charged by Lender to DHS.  Interest shall be calculated on the basis of
a 365 or 366 day year (as applicable) and shall accrue for each day such Loan is
not repaid  (with a minimum of one day's  interest  due for any advance  made by
DHS).  Except as provided in the following  paragraph,  the obligation of DHS to
repay any amounts due in respect of any Loan shall be absolute,  irrevocable and
unconditional  and  shall  be due  and  payable  in all  circumstances,  without
limitation,  notwithstanding  any of the following:  (a) any lack of validity in
any instrument  evidencing any of DHS' obligations to Lender; (b) any amendment,
modification  or waiver of any  instrument  evidencing  any obligation of DHS to
Lender (whether or not SJMC shall have knowledge thereof);  (c) the existence of
any claim,  set-off,  defense or other rights  which DHS may have against  SJMC,
whether in connection with this or any other transaction;  (d) the invalidity or
non-conformance  of any  claim  for  payment  by  Lender  against  DHS;  (e) the
bankruptcy  or  insolvency  of  DHS  or  SJMC;  or (f)  any  other  circumstance
whatsoever, whether or not similar to any of the foregoing.

         3. So long as the  Guaranty  shall  remain  outstanding  or there shall
remain unpaid any amounts  payable by DHS in respect of the principal  amount of
any Loans  hereunder,  any amount paid by

<PAGE>


SJMC in respect of the principal due under the Non-Negotiable,  Non-Transferable
Promissory Note of SJMC dated February 24, 1995, shall first be  applied  by DHS
immediately  to reduce the principal amount of the Guaranteed Obligations  or to
repay the principal of any Loans hereunder.

         4. As security  for the  repayment of all amounts due in respect of any
Loan, DHS hereby grants to SJMC a continuing  lien and security  interest in and
to the following property (collectively, the "Collateral"):

                  (a) Receivables - all accounts, accounts receivable,  contract
         rights,  chattel paper,  negotiable and non-negotiable  instruments and
         agreements,  and general  intangibles (as such terms are defined by the
         Maryland Uniform Commercial Code);

                  (b) Interest in Agreements - each of the agreements listed  on
         Exhibit D hereto,  including all  replacements, renewals, substitutions
         and additions thereto; and

                  (c) Proceeds and Products - all cash and non-cash proceeds and
         products  of  any  services,   property  or  goods   described  in  the
         subparagraphs (a) and (b) above,  including,  without  limitation,  all
         cash,  moneys,  funds,  securities  or other  instruments  both now and
         hereafter  on  deposit  or held by DHS,  Lender  or SJMC in any bank or
         other account  established and maintained by SJMC or by SJMC and DHS or
         by DHS in  connection  with  any  loans,  letter  of  credit  or  other
         financial accommodation both now and hereafter extended by SJMC to DHS.

         SJMC  acknowledges  and  agrees  that DHS has  granted or will grant in
favor of Medical Mutual a lien and security interest in the Collateral.

         For the benefit and security of SJMC,  DHS hereby grants to SJMC all of
the rights heretofore  granted to Medical Mutual Liability  Insurance Society of
Maryland  ("Medical  Mutual")  set  forth  in  Article  6 of  the  Final  Credit
Enhancement  Agreement  dated  as of  December  1,  1995  (the  "Medical  Mutual
Agreement"),  between SJMC and Medical Mutual, the terms and provisions of which
Sections  are hereby  incorporated  herein by reference  (without  regard to any
amendment or modification  thereof entered into between DHS and Medical Mutual),
which rights may be exercised by SJMC, Medical Mutual or both, in such manner as
they shall between them agree.

         5.       As  a  condition  to  the  effectiveness   hereof  and  to the
execution  and delivery by SJMC of the  Guaranty,  DHS  shall deliver,  or cause
to be delivered, to SJMC, the following:

                  (a)      a promissory note evidencing its payment  obligations
         hereunder in substantially the form attached hereto as Exhibit A;

                  (b) a financing  statement  evidencing  the liens and security
         interests  granted pursuant to paragraph 4 above, in substantially  the
         form attached hereto as Exhibit B;

                  (c)      a Collateral Assignment of Contracts in substantially
         the form attached hereto as Exhibit C;

                  (d)      the  Consent  and  Agreement of Medical Mutual in the
         form attached to this Agreement;

                  (e) an opinion of Thomas F. Mapp,  Corporate  Counsel for DHS,
         in form and substance  reasonably  satisfactory to SJMC with respect to
         the  validity  and  enforceability  of each  agreement  and  instrument
         executed  and  delivered  by  DHS  to  SJMC  in  connection   with  the
         transactions contemplated hereby; and

                                       2

<PAGE>

                  (f) such other  certificates,  agreements  and  instruments as
         shall   reasonably  be  required  by  SJMC  in   connection   with  the
         transactions contemplated hereby.

         6. So long as any of the Guaranteed  Obligations are  outstanding,  DHS
shall comply with each of its covenants and agreements set forth in Article 7 of
the Medical Mutual  Agreement  (other than Sections 7.1(c) and 7.1(d)  thereof),
each of  which  covenants  and  agreements  is  hereby  incorporated  herein  by
reference.  All  references in the Medical  Mutual  Agreement to (i) the "Lender
Documentation"  shall mean and include  the Lender  Documentation  as  described
therein and each and all  agreements and  instruments  executed and delivered by
DHS in favor of the Lender in respect of the  Guaranteed  Obligations,  and (ii)
"PSO  Agreement"  shall  mean  each  of  the  agreements  of  DHS  described  in
subparagraph (b) of paragraph 4 above.

         7. In order to induce  SJMC to enter into this  Agreement  and to issue
the Guaranty, DHS makes the following representations and warranties to SJMC:

                  (a)  Corporate  Existence.  DHS is  duly  organized,  validity
         existing and in good standing  under the laws of the State of Maryland,
         has the corporate  power to own its assets and to transact the business
         in  which  it is  now  engaged  and  is  duly  qualified  as a  foreign
         corporation  and in good  standing in each  jurisdiction  in which such
         qualification is required.

                  (b) Corporate Power;  Authorization;  Enforceable  Obligation.
         DHS has the  corporate  power,  authority  and legal  right to execute,
         deliver and perform this  Agreement  and each  agreement or  instrument
         delivered  to lender in  connection  with the  insurance  by DHS of the
         Guaranteed  Obligations  (collectively the "Lender  Documentation") and
         has taken all necessary  corporate  action to authorize the  execution,
         delivery and performance thereof. No consent, license, permit, approval
         or   authorization   of,   exemption   by,  notice  or  report  to,  or
         registration, filing or declaration with, any governmental authority is
         required  for the  execution,  delivery and  performance  by it of this
         Agreement  or the  Lender  Documentation  which has not been  obtained,
         made,  given or accomplished  (other than federal and state  securities
         laws, as to which no  representation  is made).  This Agreement and the
         Lender  Documentation  have been  executed  and  delivered  by its duly
         authorized officer,  and each of such agreements  constitute,  a legal,
         valid  and  binding  obligation  of  DHS,  enforceable  against  DHS in
         accordance with its terms,  except as enforceability  may be limited by
         bankruptcy  insolvency,  reorganization,  moratorium  or  similar  laws
         relating  or  limiting  creditors'  rights  generally  or by  equitable
         principles relating to enforceability.

                  (c) No Legal Bar. DHS' execution,  delivery and performance of
         this  Agreement  and the  Lender  Documentation  will not  violate  any
         provision  of any existing law or  regulation  applicable  to it (other
         than federal and state securities  laws, as to which no  representation
         is made),  or of any  order,  judgment,  award or decree of any  court,
         arbitrator  or   governmental   authority   applicable  to  it  or  its
         certificate  of  incorporation  or by-laws or any mortgage,  indenture,
         lease, contract or other agreement,  instrument or undertaking to which
         it is a party or by which it or any of its  assets  may be  bound,  and
         will  not,  except  as  otherwise  provided  herein or under any of the
         Lender Documentation, result in, or require, the creation or imposition
         of any Lien on any of its property,  assets or revenues pursuant to the
         provisions of any such mortgage,  indenture,  lease,  contract or other
         agreement, instrument or undertaking.

                  (d) No Material  Litigation.  No litigation,  investigation or
         administrative  proceeding  of  or  before  any  court,  arbitrator  or
         governmental  authority  is pending nor, to its  knowledge,  threatened
         against DHS or any of its assets (i) with respect to this  Agreement or
         the

                                       3

<PAGE>

         Lender Documentation or (ii) that would have a material adverse  effect
         on its business, operations, assets or financial  or other condition.

                  (e)      ERISA.  DHS has  never  established,  terminated   or
         been  required  to make  contributions  to any Plan (as  defined in the
         Medical Mutual Agreement).

                  (f) Security Interest.  (i) No effective  financing  statement
         listing the DHS as debtor  (other than any which may be filed on behalf
         of SJMC or Medical Mutual (but only to extent  described in the Medical
         Mutual  Agreement)  or  other  lending  institution   authorized  SJMC)
         covering any of the Collateral is on file in any public office and (ii)
         DHS has not created any security  interest  which  remains in effect in
         the Collateral and will keep the Collateral and every part thereof free
         and clear of all liens, security interests or other encumbrances except
         the liens and security  interests granted pursuant to this Agreement or
         in favor of Medical Mutual as described in the Medical Mutual Agreement
         and any other liens or security interest permitted in writing by SJMC.

                  (g) Not an Investment  Company or Holding Company.  DHS is not
         an  "investment  company" or an  "affiliated  person" of, or "principal
         underwriter"  or "promoter"  for, an "investment  company",  within the
         meaning of or subject to regulation under the Investment Company Act of
         1940, as amended. The obtaining of the loans provided by Lender by DHS,
         the application of the proceeds  thereof by DHS and the consummation of
         the transactions  contemplated  hereby or by Lender  Documentation will
         not violate any provision of such Act or any rule,  regulation or order
         issued by the Securities and Exchange Commission thereunder.

                  (h) Compliance  with Laws. DHS is not in violation of any law,
         rule or regulation (other than federal and state securities laws, as to
         which no  representation  is made),  or in default  with respect to any
         judgment,  writ,  injunction or decree of any  governmental  authority,
         where such  violation  or default  could  result in a material  adverse
         effect  on its  business,  operations,  assets  or  financial  or other
         condition.

                  (i)      Tax Returns.  DHS has filed all  federal,  state  and
         local tax returns  required to have been filed by it and paid all taxes
         as  shown  to  be due and payable on such returns or on any assessments
         received by it.

                  (j)      Incorporated  Representations  and Warranties.   Each
         of  the  representations  and  warranties  of  DHS  set  forth  in this
         Agreement or in the Lender Documentation or in connection therewith  is
         true and correct in all material respects.

                  (k) Disclosure. To the best of its knowledge,  information and
         belief,  neither  this  Agreement  nor  any  document,  certificate  or
         financial  statement  furnished  to SJMC or the Lender by DHS or on its
         behalf in  connection  herewith  contains  any  untrue  statement  of a
         material fact or omission of any material fact.

         8. If any of the  following  events  shall  occur  (each an  "Event  of
Default"),  SJMC shall be entitled to exercise the rights and remedies described
in paragraph 9 below:

                  (a)      DHS  shall  fail to  repay  any  amount  due to  SJMC
         hereunder  when  due or to  Lender  under  the  Lender  Documentation;

                  (b) DHS shall  breach or fail to perform any of the  covenants
         or agreements  set forth in this  Agreement  (other than as provided in
         (a) above) or in any of the  agreements  and

                                       4

<PAGE>

         instruments  described  to  Lender  in  connection  with the Guaranteed
         Obligations  which breach or failure is not cured  within  fifteen (15)
         calendar  days after notice from SJMC to DHS;

                  (c) Any  representation  or warranty  made by DHS herein or in
         the Lender  Documentation  shall  prove to have been  incorrect  in any
         material respect when made;

                  (d) Any lien or security interest in the Collateral encumbered
         hereby  shall cease to be a valid and  enforceable  perfected  security
         interest in favor of the SJMC,  or DHS shall so assert in  writing,  or
         any of the Collateral shall be subject to any lien or security interest
         other than as permitted hereunder or authorized by SJMC;

                  (e)      An Insolvency Event (as defined in the Medical Mutual
         Agreement) shall have occurred with respect to DHS;

                  (f) Any event or condition shall occur and be continuing which
         permits  any lender to DHS to declare  any  Material  Indebtedness  (as
         defined in the Medical  Mutual  Agreement) of DHS for money borrowed to
         become due and payable prior to its scheduled  maturity  date, or there
         shall occur an  acceleration  of any of such  indebtedness  (including,
         without limitation,  any of the indebtedness of DHS to or guaranteed by
         Medical Mutual);

         Notwithstanding  the  foregoing,  none  of  the events described above,
other  than  an  event  described  in ( e) above,  shall  constitute an Event of
Default  hereunder unless and until DHS shall  have  notice   thereof  and shall
have failed to cure  such default  within 30 days after  notice;  provided  that
(i) DHS shall be deemed to have notice of any event described in (a) above,  and
(ii) in  the  case  of  an event described in (f) above DHS shall be entitled to
cure such  default only so long as the lender shall not have taken any action to
exercise  any remedy  against DHS other than the giving of a notice of a default
and a demand for payment thereof.

         9.       (a) In addition to all other rights and remedies  provided by
law SJMC,  on the  occurrence of any Event of Default, may:

                  (i)  Accelerate  and  call  due any amounts due from DHS under
         paragraph  2 above and all accrued  interest  and other sums  due as of
         the date of default;

                  (ii)  Accelerate  and  prepay  on  DHS'  behalf,  and  for the
         account of DHS, any of the Guaranteed Obligations;

                  (iii)  Foreclose  or  enforce all  or  any security interests,
         liens, assignments, or pledges created hereunder;

                  (iv)  Confess judgment or file suit against  the  Borrower  on
         the Note;

                  (v)  File suit against the borrower on this Agreement;

                  (vi) Seek specific performance or injunctive relief to enforce
         performance of the  undertakings,  duties,  and agreements  provided in
         this Agreement,  and that the instrument  executed and delivered by DHS
         in  favor of SJMC in  connection  with  the  transactions  contemplated
         hereby, whether or not a remedy at law exists or is adequate; and

                  (vii)  Exercise  any  rights of a secured  creditor  under the
         Uniform Commercial Code, as adopted and amended in Maryland,  including
         the  right to take  possession  of the  Collateral  without  the use of
         judicial process or hearing of any kind.

                                       5

<PAGE>

                  (b) The rights and  remedies  provided  in this  Agreement  or
otherwise  under  applicable  laws shall be  cumulative  and the exercise of any
particular  right or remedy  shall not  preclude  the  exercise of any rights or
remedies in addition to, or an alternative of, such right or remedy.

         10. This  Agreement  shall be  terminated,  and the  Borrower  shall be
released from liability hereunder on the date which is the last to occur of: (a)
the full and final  payment to SJMC of all amounts owed to SJMC pursuant to this
Agreement or (b) the date of expiration of the Guaranty.

         11. No  failure  or delay on the part of SJMC to  exercise  any  right,
power or privilege  under this  Agreement and no course of dealing  between DHS,
SJMC, the Lender or any of their respective affiliates shall operate as a waiver
thereof,  nor shall any  single  or  partial  exercise  of any  right,  power or
privilege  under this  Agreement  shall  preclude any other or further  exercise
thereof or the exercise of any other right,  power or  privilege.  To the extent
permitted  by law,  the  rights  and  remedies  herein  expressly  provided  are
cumulative  and not  exclusive  of any  rights  or  remedies  which  SJMC  would
otherwise have pursuant to law or equity. No notice to or demand on any party in
any case shall  entitle  such party to any other or further  Nortek or demand in
similar or other circumstances, or constitute a waiver of the right of the other
party to any other or  further  action in any  circumstances  without  notice or
demand.  In the  event  that the  consent  of SJMC is  required  under the terms
hereof, it is understood and agreed that except as otherwise  provided expressly
herein,  the  determination  whether to grant or withhold  such consent shall be
made solely by SJMC in its absolute discretion.

         12. This Agreement may not be amended, waived, supplemented,  restated,
or otherwise modified except by written agreement signed by SJMC and DHS.

         13. (a) DHS agrees to pay, and to hold SJMC harmless from all liability
for, any stamp taxes imposed by future  changes in law  (including  interest and
penalties,  and fees) which may be payable in connection  with this Agreement or
the issuance of the Guaranty or any modification of any of the foregoing.

                  (b) DHS shall (i)  indemnify  and hold  harmless SJMC and each
director,  officer,  employee and affiliate thereof from and against all losses,
claims,  damages,  expenses  or  liabilities  to  which  SJMC or such  director,
officer,  employee  or  affiliate  may become  subject  insofar as such  losses,
claims,  damages,  expenses or  liabilities  (or actions,  suits or  proceedings
including any inquiry or  investigation or claims in respect thereof) are caused
by or result from any errors or omissions of DHS  hereunder  and (ii)  reimburse
the SJMC and each director,  officer,  employer or affiliate  thereof upon their
demand,  for any  reasonable  legal or other expense  (including  the reasonable
allocated costs of staff counsel) incurred in connection with the investigating,
preparing to defend or defending any such loss, claim, damage, liability, action
or claim; provided however, that DHS shall not be required to indemnify SJMC for
any claims, damages, losses,  liabilities,  costs or expenses to the extent, but
only to the extent, caused by the willful misconduct or gross negligence of such
person or  entity.  If any action is brought  against  SJMC or any other  person
indemnified or intended to be indemnified pursuant to this paragraph, DHS shall,
if  requested  by SJMC or any such  indemnified  person,  resist and defend such
action,  suit or  proceeding  or cause the same to be resisted  and  defended by
counsel reasonably satisfactory to the person or persons indemnified or intended
to  be  indemnified.  Each  indemnified  person  shall,  unless  SJMC  or  other
indemnified  person has made the request described in the preceding sentence and
such request has been  complied  with,  have the right to employ its own counsel
(or staff  counsel) to  investigate  and control the defense of any other matter
covered by such indemnify and the  reasonable  fees and expenses of such counsel
shall be at the expense of DHS.

                  (c) All  obligations  provided  for in this  paragraph  herein
shall survive any termination of this Agreement and the Guaranty.

         14. This Agreement  shall bind, and the benefits hereof shall inure to,

without the prior written consent of the other party.

         19.  DHS  HEREBY  IRREVOCABLY  WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY
ACTION,  PROCEEDING  OR  COUNTERCLAIM  ARISING  OUT OF OR RELATING TO ANY OF THE
TRANSACTIONS CONTEMPLATED HEREBY.

         20. (a) DHS hereby irrevocably and  unconditionally  submits for itself
and its property, to the non-exclusive  jurisdiction of any Maryland State court
and Federal courts of the United States of America sitting in Maryland,  and any
appellate court from any thereof,  in any action or proceeding arising out of or
relating to this  Agreement,  or for recognition or enforcement of any judgment,
and each of such parties hereto hereby  irrevocably and  unconditionally  agrees
that all  claims in respect of any such  action or  proceeding  may be heard and
determined  in such State of Maryland or, to the extent  permitted  by laws,  in
such Federal court.  Each of such parties hereto agrees that a final judgment in
any such action or proceeding  shall be conclusive  and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

                  (b) DHS hereby irrevocably and unconditionally  waives, to the
fullest extent it may legally and effectively do so, any objection it may now or
hereafter have to the laying of venue of any suit, action or proceeding  arising
out of or relating to this  Agreement  in any Maryland  State or Federal  court.
Each of the parties  hereto hereby  irrevocably  waives,  to the fullest  extent
permitted by law, the defense of an  inconvenient  forum to the  maintenance  of
such action or proceeding in any such court.

                  (c) To the  extent  permitted  by  law,  each  party  to  this
Agreement  irrevocably consents to service of process in the manner provided for
notices herein.  Nothing in this Agreement will affect the right of any party to
this Agreement to serve process in any other manner permitted by law.

         21. In the event any provision of this Agreement  shall be held invalid
or  unenforceable  by any court of competent  jurisdiction,  the parties  hereto
agree that such holding shall not invalidate or render  unenforceable  any other
provision  hereof or thereof.  The parties hereto further agree that the holding
by any court of competent jurisdiction that any remedy pursued by SJMC hereunder
is unavailable or unenforceable  shall not affect in any way the ability of SJMC
to pursue any other remedy available to it.

                                       8

<PAGE>


         22. This Agreement  completely  sets forth the  agreements  between the
parties  and fully  supersedes  all prior  agreements,  both  written  and oral,
relating to all matters set forth herein.

         23. All  references to the Medical  Mutual  Agreement  herein or to any
term defined in the Medical Mutual Agreement shall mean and refer to the Medical
Mutual  Agreement  and the terms  defined  therein as  originally  executed  and
delivered,  a true and correct  copy of which has been  provided by DHS to SJMC,
without  regard  to any  amendment,  modification,  supplement  or other  charge
thereto as may be agreed between DHS and Medical Mutual.

         24.      DHS hereby acknowledges that:

                  (a)  it  has  been  advised  by  counsel  in  the negotiation,
         execution and delivery of this Agreement;

                  (b)  SJMC  has  no  fiduciary  relationship  to  DHS  and  the
         relationship between SJMC, on the one hand, and DHS, on the other hand,
         is solely that of creditor and debtor.

         25. SJMC and DHS shall  cooperate  and use their best efforts to secure
for DHS loans from the Lender in an aggregate  principal  amount of at least $10
million  (including  amounts necessary to refinance the Guaranteed  Obligations)
prior to October 1, 1996.  It is the intention  and  expectation  of the parties
that SJMC will provide a loan  guaranty of up to $10 million and, in  connection
therewith,  that the  management of SJMC will undertake to obtain (to the extent
not already obtained) all required corporate approvals of such guaranty.

                                             Very truly yours,

                                             ST. JOSEPH MEDICAL CENTER, INC.

                COLLATERAL ASSIGNMENT OF RIGHTS UNDER AGREEMENTS


         THIS   COLLATERAL   ASSIGNMENT   OF  RIGHTS  UNDER   AGREEMENTS   (this
"Assignment") is entered into as of this ______ day of August,  1996, by DOCTORS
HEALTH SYSTEM, INC., a Maryland corporation (the "Assignor"), for the benefit of
ST.  JOSEPH  MEDICAL  CENTER,  INC.,  a  Maryland  nonprofit  corporation,   its
successors and assigns ("SJMC").

                             Explanatory Statement

                  WHEREAS,  the Assignor and SJMC have entered into an Agreement
of even date herewith (the "Agreement"),  whereby the parties have agreed, among
other things,  that SJMC will  guarantee  certain  financial  obligations of the
Assignor  in  consideration  for which the  Assignor  will  transfer  and assign
certain  rights and other  assets of the Assignor to SJMC in order to secure the
obligations  of the  Assignor  to SJMC  that may  arise  from  time to time (the
"Credit Enhancement Arrangement");

                  WHEREAS,  the  Assignor  desires to assign all of its  rights,
title and  interest  in and to,  and  remedies  under,  certain  contracts  more
particularly  described  in  Schedule  I  hereto  (collectively,  the  "Assigned
Contracts") rights; and

                  WHEREAS,  the  Assignor  recognizes  that SJMC is unwilling to
enter into the Credit Enhancement Arrangement unless this Assignment is executed
and  delivered  by the  Assignor.  The  Assignor  is  willing to enter into this
Assignment so that SJMC will enter into the Credit Enhancement Arrangement.

                  NOW,  THEREFORE,  in consideration of the premises,  to induce
SJMC to enter into the  Credit  Enhancement  Arrangement  and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby

and pursuant to the Assigned Contracts, including but not limited to any and all
rights or rights of  enforcement,  whether  pertaining  to the Assignor or third
parties and whenever arising or coming into existence, and further including all

<PAGE>

financing  records, other  than  financing  statements  in  favor  of  SJMC  and
existing  financing statements in favor of Medical  Mutual  Liability  Insurance
Society of Maryland, and the Assignor is and  will  be the legal owner of all of
the  Collateral,  free and clear of all liens, security interests,  encumbrances
and claims whatsoever; (b) the Assignor is duly  authorized  to  enter  into and
perform this  Assignment; (c) the execution and  performance by the Assignor  of
this  Assignment  does not violate, breach or constitute  a  default  under  any
contract or agreement to which the  Assignor  is  or  may  become a party or any
federal, state,  county, city  or municipal statute, rule, regulation, ordinance
or law;  (d)  this   Assignment  constitutes   the  valid  and  legally  binding
obligations  of the Assignor and is fully  enforceable  against  the Assignor in
accordance  with its terms;  and (e) there  is  no  Litigation and there are  no
actions,  suits,  complaints or proceedings of any kind, whether administrative,
regulatory  or  otherwise, pending or  threatened  against  the  Assignor  which

affect  adversely  its  business,  property,  assets  or  ability  to  pay   its
obligations to SJMC, and (f) none of the Assigned  Contracts has been amended or
modified since its original dates of execution and delivery except as  described
in Schedule I hereto.

         5.  Covenants  of the  Assignor.  The Assignor  covenants  that (a) the
Assignor  shall  keep  and  maintain  in  accordance  with  generally   accepted
accounting  principles  current,  accurate and  complete  books and records with

condition of the Assignor,  including such  information as SJMC may from time to
time  require;  (b) the  Assignor  shall not sell,  discount,  assign,  lease or
otherwise  transfer or dispose of any of the  Collateral  without  SJMC's  prior
written consent,  which consent shall be at the sole and absolute  discretion of
SJMC; (c) the Assignor will not make any amendment subsequent to the date hereof
to any of the Assigned Contracts that materially  adversely affects the value of
any of the Assigned Contracts or the rights of SJMC as Guarantor pursuant to the
Agreement  without SJMC's prior written  consent;  (d) the Assignor shall permit
SJMC,  and any of their agents and designees,  at any  reasonable  time or times

Collateral  and any other assets of the  Assignor,  to reproduce and copy all or
any part of any books and  records of the  Assignor  or other  documents  in the
Assignor's  possession,  and to verify,  by such  means as SJMC shall  determine

information  relating  to the  obligations  of the  Assignor  to SJMC and/or the
Collateral;  (e) the  Assignor  shall  immediately  notify SJMC of the threat or
commencement of any litigation,  action,  suit or proceeding of any kind against
the Assignor or the  occurrence of any event or  circumstance  which  materially
adversely  affects,  or which could  reasonably  be deemed to affect  materially
adversely, SJMC's security interest or any of the Collateral, including, but not
limited  to,  any  damage to or loss or  destruction  of any  books and  records
relating to the Collateral;  and (f) the Assignor shall immediately  notify SJMC
of any event or circumstance  which  constitutes a default under this Assignment
or under any of the Assigned Contracts and of any material adverse change in the
Assignor's financial condition or business operations.

         6. SJMC Not  Obliged  Under  Assigned  Contracts.  SJMC  shall  have no
obligation or duty to perform any of the  obligations  of the Assignor under the
Assigned  Contracts,  all of which shall remain the sole and exclusive  duty and
obligation of the Assignor.  The Assignor agrees to fully and completely perform
all of the terms and provisions of the Assigned  Contracts and otherwise satisfy
is  obligations  thereunder so that the rights hereby  assigned to SJMC shall be
and remain fully and completely enforceable at all times.

         7. SJMC May Enforce Rights Under Assigned Contracts.  In the event of a
default by the Assignor with respect to any of its obligations to SJMC hereunder
or under the Credit Enhancement Arrangement or the occurrence or continuation of
such a default, SJMC may, subject to any period of notice and grace set forth in
the Credit Enhancement Agreement, enforce, either in its own name or in the name
of the Assignor, all rights of the Assignor under the Assigned Contracts and may
(a)  bring  suit to  enforce  any  rights  under  the  Assigned  Contracts,  (b)
compromise  or  settle  any  disputed  claim as to  rights  under  the  Assigned
Contracts,  (c) give  releases or  acquaintances  of rights  under the  Assigned
Contracts,

or  (d)  do  any  and  all  things  necessary, convenient or proper to fully and
completely  effectuate  the  collateral  assignment  of  the  rights  under  the
Assigned Contracts pursuant hereto. The Assignor hereby constitutes and appoints
SJMC or SJMC's  designee  as the  Assignor's  attorney-in-fact  with full  power
following an Event of Default in the Assignor's  name,  place and stead to do or

                                 _____________

                                   Background
                                 _____________

                  The Company  desires to  hire  Executive,  and  the  Executive
desires to work for the Company,  on the terms and conditions set forth in  this
Agreement.

                  1.       Employment, Duties and Acceptance.

affiliates of the Company and others  as may be  requested  by the CEO.  Whether
or not the  Executive  is then serving as a member of the Board of Directors  of
the  Company,  the  Executive  shall  have the  right  to attend and participate

Directors,  including  meetings  of  the  Executive   Committee.   thereof.  The
Executive shall perform his duties faithfully and to the best of his abilities.

<PAGE>

                                    (b)  The  Executive   shall,    subject   to
Section  1.1(c)  hereof,  devote his full working time and creative  energies to
the  performance  of  his  duties  hereunder  and  will at all times devote such
additional  time  and  efforts  as are   reasonably  sufficient  for  fulfilling
the  significant  responsibilities  entrusted  to   him.   So   long   as   such
activities,  in the  aggregate,  do not interfere  with the  performance  by the
Executive  of  his  duties   hereunder:  (i)  the Executive shall be permitted a
reasonable  amount  of  time to supervise his  personal,  passive,  investments;
(ii) the Executive shall be permitted a reasonable amount of time to participate
(as  board  member,  officer or  volunteer) in civic,  political  and charitable
activities;  (iii) the Executive  shall  be  permitted  to  deliver lectures  to
and  teach  at  educational  institutions  and business organizations;  and (iv)
subject  to  the  provisions  of Section 5 hereof,  the Executive may serve as a

Company.  Until April 30, 1997, the  Executive   shall  be  permitted   to spend
approximately  fifteen (15)  hours  per  month  to  wind-up  the  affairs of his

subject to such travel as may be reasonably  required by his employment pursuant
to the terms  hereof.  The  Executive  shall not be required to relocate outside
of the Washington,  D.C.-Baltimore, Maryland  metropolitan  area during the Term
unless the Company  provides relocation benefits acceptable to the Executive  in
his sole discretion.

                  2.  Term of Employment. The term of the Executive's employment
under this Agreement (the "Term") shall commence on the Effective Date and shall
end on April 30, 2000, unless sooner terminated,  or later extended,  as  herein
provided.  Not later than February 1, 2000 (and each February 1 of each calendar
year  during  any  Extension  Period (defined  below)),  the  Company  and   the
Executive shall enter into good faith  negotiations to determine  whether and on
what terms to extend or renew this  Agreement  beyond April 1  of such  calendar
year. If by October 15, 1999 (and October 15  of  any  calendar  year  occurring
during an Extension  Period) either party gives  written  notice to the other of
its desire to terminate  this Agreement as of April 1, then this Agreement shall
so terminate,  and the Executive shall be permitted a reasonable  amount of time
during  the  balance  of the Term within which to explore alternative employment
opportunities.  If no such  written notice to terminate is given by either party
by October 15, 1999 (or by October  15 of any calendar year occurring  during an
Extension  Period),  then  the  Term   shall,   without   further  act  or deed,
automatically  be  extended  upon the  same  terms and  conditions as previously
in effect,  for  an  additional  12  month  period,  commencing  on May 1 of the
applicable  calendar year and ending on April 30 of  the  immediately  following
calendar  year.   Each  such  12 month extension  during the Term is referred to

                                       2

<PAGE>

part of the Term of this  Agreement for all purposes, including  the  provisions
regarding extensions contained in this Section 2.

                  3.       Compensation.

rendered pursuant to this Agreement, the Company  shall pay  to  the  Executive,
during  the  Term,  a "Base Salary" (as  defined  in this Section 3.1) less such

regulations.   The  "Base Salary"  shall be a salary of $195,000 per annum.  The
Base Salary shall accrue from and after the Effective Time, and shall be payable
during the Term, in arrears in equal bi-weekly installments.

                           3.2      Bonus Pool.  (a) Beginning with the calendar
year 1996,  the Company  shall establish  for the benefit of the  Executive  and
certain  other  Company  employees a "Bonus Pool" with respect to  each calendar
year, or portion thereof, that occurs during the Term (each a "Bonus Year").

                                    (b)     During the Term, except as otherwise
provided  herein,  the Executive shall be entitled to  participate  in the Bonus
Pool  to  the  extent  agreed to between  the  Executive  and the CEO, provided,
however,  that for calendar years 1996 and 1997, the Executive's bonus shall  be
determined in accordance with  Schedule  3.2(b)  attached  hereto.  On or before
the  fifteenth  day  of  December  in  each year during the term beginning  with
December 15, 1997, the Executive and the  CEO  shall  agree upon the performance
standards  and potential  awards for the Executive  applicable to the Bonus Year
beginning  on  the  next  following  January  1.  All  amounts  allocated to the
Executive  pursuant to this Section 3.2 shall become  payable to  the  Executive
and are hereinafter collectively  referred to as the "Bonus".  The amount of the
Executive's Bonus for each Bonus Year, if any, shall be determined by the  first
day of March,  and paid by the  fifteenth day of March, next following the Bonus
Year for which the Bonus is payable.

                                    (c)  Upon  any  Change  in  Control  of  the
Company (as herein defined),   all  accrued   Bonus  amounts  reflected  on  the
Company's  internally  prepared  financial  statements  shall become  payable to
the Executive.

                           3.3      Stock  Options.  As soon  practicable  after
the date of this  Agreement,  the Company will grant to the Executive  qualified
incentive  stock  options  (the  "Options")  to  purchase  70, 000 shares of the
Company's  Class  A  Common  Stock  (the   "Option  Shares")   pursuant  to  the
Company's   Omnibus  Stock  Option  Plan  or  other   stock  benefit  plan  (the
"Plan"). The  exercise   price  of  such   Options  shall  be 11.00  per  share,
representing  the  fairmarket  value  of  the  Option  Shares.  In  addition  to
the  70,000  options  issued  to the Executive  on the date hereof,  the Company
is  contemplating,  subject to  approval  of the appropriate  committee  of  the
Board of Directors,  the  issuance  of  an  additional  30,000  options  to  the
Executive,  which  options  will  vest  over  at least a

                                       3

four year period and be granted with or without  a  significant  exercise  price
and  with  significant  conditions  to  exercise  based  upon earnings and other
criteria.

                           (b)  The  Executive   agrees  to and shall  execute a
stockholder's  agreement  restricting  his  ability  to  transfer  shares of the
Company's  Class A Common Stock,  or  any  other  shares of the Company's  stock
which the Executive may own or in which the  Executive may have an interest,  in
form  substantially  similar to the stockholders  agreement  attached  hereto as
Appendix A (the "Stockholder's Agreement").

                           (c)  Nothing  in  this  Section  3.3  shall adversely
effect the Executive's right to participate, together  with other  key employees
of the Company,  in any future  grants of options, stock or other equity related
vehicles  by the  Company  pursuant  to the Plan as in effect from time to time.
All such future grants shall be subject to the terms of the Plan as in effect at
the time of grant.

                           3.4.     Withholding.   The   Company  is  authorized
to  withhold  from the amount of any Salary,  Bonuses,  and any other things  of
value paid to or for the benefit of the Executive,  all sums  authorized by  the
Executive or required to be withheld by law, court decree,  or executive  order,
including (but not limited to) such things as income  taxes,  employment  taxes,
and employee  contributions to fringe benefit plans sponsored by the Company.

                           3.5      Participation  in Executive  Benefit  Plans.
The Executive  shall be permitted during the Term, if and to the extent  legally
eligible,  to  participate  in  any  group  life,  health,   hospitalization  or
disability  insurance  plan,  health  program,  automobile   allowance,  pension
plan or similar benefit plan of  the  Company  which may be available  to  other
comparable executives or professional employees,  including  physicians,  of the
Company  generally on the same terms as such other  executives.  All group life,
health,  hospitalization  and disability plan or policy premiums  applicable  to
participation  in  such  plans  or  policies  by  the Executive and his wife and
children (subject  to  reasonable  policy and plan limitations) shall be paid by
the Company.

                           3.6      Vacation.  The  Executive  will  receive  at
least 4 weeks vacation per year, to be  scheduled  and taken at the  Executive's
option  at  such  times  as  his duties may permit.  Should the Company's policy
provide  for  more  vacation  to  comparable  executives  the Executive  will be
accorded  such  higher  vacation. Unused vacation time shall not be cumulated or
carried  over  nor  shall  the  Executive  receive  any  compensation for unused
vacation time.

                           3.7      Expenses.  Subject to such policies  as  may
from  time  to  time  be   established  by  the Board,  the Company shall pay or
reimburse  the  Executive for all ordinary,  necessary and  reasonable  expenses
(including,  without limitation,  travel,  meetings, dues,  subscriptions, fees,
educational  expenses,  computer  equipment,  mobile   telephones,  professional
insurance,  and the like) actually incurred or paid by the

any  other  provision  of  this  Agreement,  if  during  the  Term the Executive
becomes  physically,  mentally  or  emotionally  disabled,   whether  totally or
partially,  as  determined by an  independent  qualified  physician, so that the
Executive  is,  in  the  good  faith  determination  of the Board, substantially
unable to perform his services hereunder  for (i) a  period of three consecutive
months, or (ii) shorter periods aggregating three months during any twelve month

                           4.3      Termination at Election of Company.

                                    (a)  Notwithstanding any other provision  of
this  Agreement, the Company may terminate the Executive's employment  hereunder

to  terminate  the  Executive's  employment  pursuant  to   Section 4.3(a),  and

any or for no reason,  terminate  the  Executive's employment upon 60 days prior

engaged  in  by  the  Company   constituting "constructive termination"  of  the
Executive's  employment  with the Company, which  breach, acts or omissions have
not been cured by the Company as of the end  of  such period to  the  reasonable

reasons,  effective  immediately  upon  the  delivery  by the  Executive  to the
Company of a notice to the effect that  such  breach, acts or omissions have not

that  if such  constructive termination  is caused by the Executive's incapacity
or  inability  to  serve due to a disability of the type  described  in  Section
4.2 above and the Company elects to  terminate  the Executive  pursuant  to  the
provisions of Section 4.2, the Executive  shall, for purposes of this Agreement,
be deemed to have been terminated  pursuant  to  the  provisions of Section  4.2
and not of this Section 4.4.

                                    (b)  For  purposes  of  this  Section   4.4,

executives of the Company;  (C) a combination, consolidation or merger where the
Company is not the  survivor,  any sale or issuance of Company  securities  that

entities  not having such  control on the date  hereof, or any sale, exchange or
other  disposition of all or substantially all of the Company's assets  (each  a
"Change in Control") and (D) the Executive is not elected to the Company's Board
of Directors.

Known.  Notwithstanding  anything herein to the  contrary,  the  obligations  of
secrecy  and  confidentiality  set  forth   herein   shall   not  apply  to  any
information  which  is  now  generally   publicly  known  or which  subsequently
becomes  generally  publicly known other than as a direct or indirect  result of

that  the  Executive  may  inspect  during normal business hours such records as
shall be necessary  for the purpose of  assisting  the  Executive  to  file,  or
prepare for an audit of, his personal income tax returns.

                           5.6      Executive's  Ideas,  Etc.  All   inventions,
prototypes, discoveries, improvements, innovations  and the like  ("Inventions")
and all works of original  authorship  or images that are fixed in any  tangible
medium of  expression  and  all copies  thereof ("Works")  which  are  designed,
created or developed  by  Executive,  solely or in conjunction  with others,  in
the course of  performance  of  the  Executive's  duties  which  relate  to  the
Company  Business,  shall be made or conceived for the exclusive benefit  of and
shall  be  the  exclusive  property  of  the   Company.   The   Executive  shall
immediately  notify  the  Company  upon  the design, creation or  development of
all  Inventions  and  Works.   At  any  time  thereafter, the Executive,  at the
request and expense of the  Company,  shall  execute  and deliver to the Company

or reissues  thereof,  applications for copyrights and documents or  instruments
of  assignment  or  transfer.   All Works are agreed and stipulated to be "works
made for hire," as that term is  used  and  understood within the Copyright  Act
of 1976, as amended.  To the extent  any Works are not deemed to be  works  made
for hire as  defined  above,  and to the extent  that title to or  ownership  of
any  Invention or Work and all other  rights  therein are not  otherwise  vested
exclusively in the Company, the Executive shall, without  further  consideration
but  at  the  expense  of  the  Company,  assign and transfer to the Company the
Executive's entire right, title and interest (including  copyrights and patents)
in or to those Inventions and Works.

                           5.7      Rights  and  Remedies  Upon  Breach.  If the
Executive  breaches,  or threatens to commit a breach of, any of the  provisions
of Sections 5.1 through 5.6 (the  "Restrictive  Covenants"),  the Company shall,
in addition to its right  immediately to terminate  this   Agreement,  have  the
right  and  remedy (which  right and remedy shall be  independent  of others and
severally  enforceable,  and which shall be in

                                       11

<PAGE>

addition  to,  and  not in lieu  of, any  other  rights and  remedies  available
to the  Company  under  law or in equity)  to  have  the  Restrictive  Covenants
specifically   enforced  by  any  court  having  equity  jurisdiction,  it being
acknowledged and agreed that any such breach  or  threatened  breach could cause
irreparable  injury to the Company or its Affiliates  and that money damages may
not provide adequate remedy to the Company.

                           5.8      Covenants Currently Binding Executive.   The
Executive  warrants  that his employment by the Company will not (a) violate any
non-disclosure  agreements, covenants  against competition, or other restrictive
covenants made by the Executive to or  for the benefit of any previous  employer
or partner,  or (b)  violate  or  constitute  a  breach  or  default  under, any
statute,  law,  judgment,  order,  decree,  writ,  injunction, deed, instrument,
contract,  lease,  license  or  permit  to  which the Executive is a party or by
which the Executive is bound.

                           5.9      Litigation.    There   is   no   litigation,
proceeding or investigation of any nature (either civil  or criminal)  which  is
pending or, to the best of  the  Executive's  knowledge,  threatened  against or
affecting the  Executive  and  which  would  adversely  affect  his  ability  to
substantially perform the duties herein.

                           5.10     Review.  The Executive has received or  been
given  the  opportunity  to  review  the  provisions  of this Agreement, and the
meaning and effect of each provision,  with independent  legal  counsel  of  the
Executive's choosing.

                           5.11     Severability  of  Covenants.  The  Executive
acknowledges  and  agrees  that  the  Restrictive  Covenants are reasonable  and
valid in  geographical  and temporal  scope and in all respects.  If  any  court
determines  that  any  of  the Restrictive  Covenants,  or any part thereof,  is
invalid or  unenforceable,  the remainder  of the  Restrictive  Covenants  shall
not thereby be affected  and shall be given full  effect,  without regard to the
invalid portions.

                           5.12     Blue-Penciling. If any court determines that
any  of  the  Restrictive  Covenants,  or  any part  thereof, is   unenforceable
because of the duration or geographic scope of such provision, such court  shall
have the power to reduce the  duration  or scope of  such   provision,   as  the
case may be, and, in its reduced form,  such provision shall then be enforceable
and shall be enforced.  If any such court declines to  so  revise such covenant,
the parties agree to negotiate in good faith a modification  that will make such
duration or scope enforceable.

                           5.13     Enforceability   in    Jurisdictions.    The
parties  intend to and  hereby  confer jurisdiction  to enforce the  Restrictive
Covenants upon the courts of any  jurisdiction  within the   geographical  scope
of such  Covenants.  If the courts of any one  or  more  of  such  jurisdictions
hold any  Restrictive  Covenant unenforceable  by  reason of the breadth of such
scope or otherwise, it is the intention of the parties that  such  determination
not  bar  or in any way affect the Company's  right to the relief provided above
in the courts of any other  jurisdiction  within the geographical  scope of such

                                       12

Covenants,  as  to  breaches  of  such  Covenants  in  such   other   respective
jurisdictions,  such  Covenants as they relate to each jurisdiction  being,  for
this  purpose, severable into diverse and independent covenants.

                           5.14     Extension.  If  the  Executive  violates any
Restrictive  Covenant,  the Company shall not be  deprived  of the full  benefit
of the  period of the  covenant.  Accordingly,  the  duration  of that  covenant
shall be extended by the period of any violation of that covenant.

                           5.15     Remedies.  The   Company  shall be  entitled
to injunctive  or other equitable relief because it will be  caused  irreparable
injury  and  damage by  a breach  of the  provisions  of  any of the Restrictive
Covenants.  The right to  injunctive  relief  shall include the  right  to  both
preliminary and  permanent  injunctions.   The Company  shall not be required to
post a bond or other  similar  assurance if  it  brings an action to enforce the
provisions  of  any  of  the  Restrictive   Covenants.   The  Company's right to
equitable  relief  shall  not  preclude  any  other rights or remedies which the
Company may have, all of which rights and remedies are cumulative.

                           5.16     Scope   of   Restrictions.    The    parties
expressly  acknowledge  and  agree  that nothing  contained  in this  Section  5
shall  preclude  the  Executive  from  engaging in  or  limit  the   Executive's
ability to serve as investment banker, financial  consultant, merchant banker or
attorney,  as  a  member  of,  stockholder  or  partner  in  or  employee  of  a
partnership,  professional  corporation or other entity performing such services
unless  such  services  directly  or indirectly or materially are adverse to the
interests of the Company.

                           6.1      Costs of Litigation.  If either party  files
suit  or  brings  an  arbitration  proceeding  to  enforce its rights under this
Agreement,  the prevailing  party shall be entitled   to  recover from the other
party all expenses  incurred by it in preparing  for and  in  trying  the  case,
including,  but not limited to, investigative costs, court  costs and reasonable
attorney's fees.

                           6.2      Consent to Jurisdiction.  The parties submit
to the  jurisdiction and venue of the courts of the State of Maryland.

                           6.3      No Jury Trial.  NEITHER PARTY SHALL ELECT  A
TRIAL BY JURY IN ANY ACTION,  SUIT, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR
IN ANY WAY CONNECTED WITH THIS AGREEMENT.

                           6.4      Arbitration. Any dispute between the Company

                                   1997 Bonus

subject  to  resolution  under this  Schedule (a  "Dispute")  by giving  written
notice (the  "Dispute  Notice") to the other party (the  "Responding  Party") to
such Dispute.   The Dispute  Notice shall  describe the substance of the Dispute
with  sufficient  specificity  to  give  the  Responding  Party  adequate notice
of  its  nature.  Unless  otherwise  specified, time periods  specified  in this
Schedule  6.4  shall  be calculated from the date of  the  Dispute  Notice  (the
"Commencement Date").

2.       Selection of Arbitral Panel.

         2.1.     The  Arbitral   Panel (the  "Panel")   shall  consist of three
arbitrators,  two  of  whom  (the  "Party  Designated  Arbitrators")   shall  be
selected by the parties  pursuant to Section 2.2 hereof.  The third   arbitrator
shall be a "Neutral Arbitrator" selected by  the  Party  Designated  Arbitrators
pursuant to Section 2.3 hereof.

         2.2.     The  Initiating  Party shall  designate its Party   Designated
Arbitrator  in  the  Dispute  Notice. Within  fifteen  days of the  Commencement

accounting firm.

         2.4.     Each  party  agrees  promptly  to  disclose to the other party

parties any such circumstances.

         2.5.     During  the  process  of  selecting the Neutral Arbitrator and

Parties,  determine  the need for and the nature of  discovery  and  establish a
procedural  schedule for the further conduct of the Proceeding.

4.       Discovery.

         4.1.     Discovery, appropriately limited by the nature of the Dispute,
is expressly  contemplated  and permitted.  However,  the  Parties   acknowledge
and agree that one of the  benefits of resolving  Disputes  through  arbitration

that they will endeavor to agree upon  procedures  and a schedule for  discovery
that will result in a prompt and fair hearing under these procedures.

                                       19

persuasion.

         5.4.     The Hearing shall be transcribed.

6.       Post-Hearing Procedures.

so,  shall  establish a schedule  for submission of such briefs at the close  of
Hearing.

         6.2.     Within  thirty  days of the later of the close of the  Hearing

equally by the parties.

         8.2.     The Panel shall in its Decision  and Award  determine  whether

         9.2.     Until  the  Neutral  Arbitrator  is   appointed,   any   issue
relating to the  Proceeding  that is not provided   for  in   these   procedures
shall  be  governed  by  the  Commercial  Arbitration  Rules  of  the   American

         9.3.     The Panel may grant any remedy or relief  that it  deems  just

              provided to DHS HMO Members and provide DHS with access to such
              records without charge. DHS agrees that all patient records will
              be treated as confidential and will comply with laws and

8.   Physician will participate in all utilization review, quality assurance and
     credentialing programs operated by DHS to assure or improve the quality and
     effective utilization of health care services to the DHS HMO Members
     ("QA/UR PROGRAMS"). Physician agrees not to hold DHS and other participants
     in the QA/UR Programs responsible for any reasonable recommendations made
     or actions taken in good faith with respect to Physician. Physician will
     participate in all programs developed by DHS that are designed to resolve
     DHS HMO Member grievances.
9.   Physician agrees not to bill DHS HMO Members unless the service provided
     was not a covered service under the DHS HMO Plan and the DHS HMO Member was
     given prior written notice that the services would not be covered. However,
     Physician may charge, bill, collect and keep from DHS HMO Members any
     copayments or coinsurance. Except for copayments or coinsurance, Physician
     agrees that, whether or not there is any unresolved dispute for payment,
     under no circumstances, including but not limited to nonpayment by DHS or
     DHS insolvency, will Physician make any claims, other than for copayments
     or coinsurance, against any DHS HMO Member for covered services.
10.  Physician agrees not to differentiate or discriminate in the treatment of
     patients as to the quality of services delivered to DHS HMO Members because
     of race, sex, age, religion, place of residence, health status or source of
     payment, and to observe, protect and promote the rights of DHS HMO Members
     as patients.
11.  Physician will make arrangements for twenty-four hours, seven days a week
     coverage to DHS HMO Members through other primary care physicians who
     participate in the DHS provider network.
12.  Physician agrees to respond within three days of receipt to any written

     utilize the DHS provider network when arranging for additional medical
     services required by DHS HMO Members.
14.  DHS' affiliated physicians have developed protocols and practice procedures
     applicable to fellow physician participants in the DHS provider network
     (the "DHS PROTOCOLS"). Physician agrees to follow the DHS Protocols when
     treating DHS HMO Members. If Physician should ever deem any aspect of the
     DHS Protocols to be medically inappropriate or otherwise inappropriate for
     utilization by Physician, Physician may notify DHS in writing, with
     sufficient specificity to enable DHS to respond to Physician's concerns.
15.  Physician will own and operate all aspects of his or her medical practice
     and will remain responsible for all operations of the medical practice,

16.  DHS may use Physician's name, specialty, telephone number(s), and business
     location(s) in marketing, descriptive, and other information relating to
     the DHS HMO Plans, and will include Physician as a member of the DHS
     provider network during this Agreement. Physician may nonetheless be
     precluded from participating in a DHS HMO Product by one of the DHS HMO
     Plans. In such an event, DHS will notify Physician, in writing, within 30
     days of learning of such an action, and will assist Physician, if
     requested, in seeking to overturn such an action.
17.  DHS will finalize,  in cooperation  with primary care physician
     representatives  from Doctors Health  Montgomery, LLC, the commercial and
     Medicare  primary care base capitation rates using their good faith best
     efforts to reflect the prevailing  market rate for Montgomery  County
     ("PRIMARY CARE BASE CAPITATION  RATES").  Attached as SCHEDULE A are the
     proposed DHS Primary Care Base  Capitation  Rates that DHS  believes
     reflect  prevailing  market rates for Montgomery  County.  DHS will provide
     to Physician the  finalized  Primary Care Base  Capitation  Rates agreed
     upon with Doctors  Health  Montgomery,  LLC, and  Physician  will have 3
     business  days to reject such Primary Care Base Capitation  Rates and
     terminate  this  Agreement.  Otherwise,  DHS will pay to Physician,  and
     Physician  agrees to accept from DHS as  compensation  for all covered
     services  provided by Physician to DHS HMO Members the finalized Primary
     Care Base Capitation Rates.
18.  The Primary Care Base Capitation Rate may be adjusted for age and sex of
     the DHS HMO Members. The Medicare Primary Care Base Capitation Rate will be
     INCREASED by an amount up to ten percent (10%), based upon the number of
     enrolled Medicare DHS HMO Members in Physician's panel, according to a
     formula established by DHS in cooperation with primary care physician
     representatives from Doctors Health Montgomery.
19.  All Payments of the Primary Care Base Capitation Rate will be made by DHS
     directly to Physician, by the fifth business day of the month for the prior
     month's enrollment. The percentage bonus for capitated panel size will be
     calculated at the beginning of each quarter.
20.  In order to provide  economic  incentives  for  Physicians  to provide  the
     best  possible  health care to DHS HMO Members while  fostering
     efficiencies  in utilization  and quality  assurance,  DHS'  affiliated
     physicians  have established,  and Physician will participate in, a bonus
     pool. The amount of bonus awards are determined  according to DHS' primary
     care bonus system, rewarding high clinical quality,  appropriate
     utilization,  patient satisfaction and retention and the extent of
     cooperation  with other  participating  physicians and DHS. Based upon this
     system, Physician  may receive up to 25% OF THE SURPLUS  generated in
     Physician's  panel of DHS HMO Members  after managed care expenses (up to
     a maximum of 25% of all Primary Care Base Capitation  payments received by
     Physician that year or the limits  permitted by applicable  health care
     regulations).  Physician will never be responsible for managed care losses.
     These are the sole  responsibility  of DHS.  Awards  for  calendar  year
     1996 will be paid by DHS in April of 1997.  Awards for calendar year 1997
     will be made in April of 1998.
21.  Physician understands that DHS will be paid by the DHS HMO Plans for all
     services provided by Physician to DHS HMO Members. Except for copayments
     and coinsurance, Physician will not seek to collect or accept any
     reimbursement from DHS HMO Members or the DHS HMO Plans for any covered
     services provided to DHS HMO Members.
22.  Physician will maintain, at his or her expense,  general and professional
     liability insurance coverage of not less than  $1,000,000  per claim and
     $3,000,000  per year.  Physician  will  provide DHS with copies of the
     policies or other  evidence  of  compliance  with the  insurance
     requirements.  Physician  will notify DHS when any patient of Physician
     files a claim or any notice of intent to commence legal action alleging
     professional  negligence against Physician or of the  settlement  of any
     such claim by Physician or if a judgment is rendered  against Physician in
     any such legal action.  Physician  will promptly  notify DHS in writing of
     any changes in or  cancellations  of any policy of insurance  maintained
     by  Physician.  If such policy is written on a claims made basis and such
     coverage is  discontinued,  Physician will purchase an "Extension of
     Coverage  Endorsement"  within ten (10) days of written notice of
     discontinuance and shall provide DHS with a copy of this endorsement.
23.  This Agreement will expire on DECEMBER 31, 1997 (the "TERM"), unless
     extended by mutual agreement or earlier terminated pursuant to the terms
     hereof.
24.  This Agreement may be terminated by Physician upon 90 days prior written
     notice to DHS if DHS fails to perform its obligations to Physician or to
     pay any amounts required to be paid by DHS to Physician.
25.  DHS may terminate this Agreement by notice in writing to Physician for good
     cause, or if Physician materially breaches this Agreement and such breach
     continues for a period of thirty (30) days after written notice is given to
     Physician by DHS specifying the nature of the breach. Good cause means:
     (bullet) Physician's membership in any professional organization is
              terminated for cause related to professional conduct, or Physician
              resigns from any professional organizations under the threat of
              disciplinary action for professional conduct.
     (bullet) Physician is indicted upon a charge of committing a felony or any
              misdemeanor involving moral turpitude.
     (bullet) Physician fails to comply with rules, regulations and policies
              imposed with regard to the Medicare programs or to preserve his
              or her eligibility to participate in the Medicare programs.
     (bullet) Physician fails to comply with any material DHS Protocols.
     (bullet) Physician takes any action which puts a DHS HMO Members' health
              at risk.
     (bullet) Physician loses his/her license or certificate to practice
              medicine.

26.  To the extent required to enable DHS to comply with Section 952 of the
     Medicare and Medicaid Amendments of 1980, or regulations promulgated
     pursuant thereto, Physician shall until the expiration of four (4) years
     after the furnishing of services under this Agreement, make available, upon
     written request, to the Secretary of Health and Human Services or the
     Comptroller General of the United States, or to any of their duly
     authorized representatives, this Agreement and such of Physician's books,

     costs under this Agreement.
