               1,000,000 OPTIONS TO PURCHASE CLASS B COMMON STOCK

   
     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 affiliation of medical practices 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"); and (ii) Options to
purchase Class B Common Stock ("Options," and collectively with the Class B
Common Stock, the "Securities"). Such offers and issuances may be made by the
Company from time to time in the acquisition of physician practices.
    

   
     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 affiliations of the medical practices will
involve the receipt by the Company primarily of enumerated tangible assets of
such practices and related contracts and leases. The consideration for
acquisitions 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, pursuant to which the Company and its
affiliated medical groups may also issue Securities.
    
 
   
     The terms of an affiliation are determined by negotiations between the
Company's representatives and the physicians whose practices are to be acquired.
Factors taken into account in acquisitions include the established size, quality
and reputation of the practice and the market value of the Common Stock when
pertinent. 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 the
terms of an affiliation 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, certain Federal income tax consequences and the agents or
dealers, if any, participating in the offering and sale of the Securities. 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 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'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 affiliated 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.
    
 
   
     As of May 1996, approximately 140 PCPs, 93 obstetrician/gynecologists, and
390 specialist physicians had affiliated with the Company by transferring their
practice assets or establishing long term joint venture, IPA or other
contractual relationships with the Company in five regional networks, or had
entered into binding agreements to become so affiliated. The Company also offers
to Affiliated Physicians in Core Medical Groups certain patient care management,
administrative and financial services, including information systems,
contracting for and providing facilities, equipment and other goods. While
primary care-based, the Company encourages its Core Medical Groups' affiliated
physicians to develop into multi-specialty group practices and provides or
arranges financing to allow such Core Medical Groups to develop into diversified
multi-specialty practices. The Company also offers information systems and
related services to certain physicians who are not part of a Core Medical Group
but have become members of the Company's network of health care providers. See
"Business -- Development of Integrated Health Care Delivery System."
    
 
   
     The Company offers medical groups and independent physicians a variety of
affiliation models. These affiliations are carried out by the acquisition of
certain medical practice assets, either for cash or through equity, or by
affiliation on a contractual basis. The Company typically enters into Physician
Services Organization Agreements with the Core Medical Groups, pursuant to which
the Company provides care management services, managed care contracting and
related business management. The physicians are allowed to maintain their
clinical independence.
    
 
   
     The Company's strategy is to capitalize upon changes in the health care
industry by (i) affiliating with primary care practices and using their related
patient base to attract high quality specialist physicians as partners and to
integrate a full spectrum of health care providers into one or more high
quality, cost effective health care delivery networks, (ii) providing HMOs and
other similar payors with a single source of access to geographically proximate
networks of physicians, and other providers, (iii) focusing on obtaining HMO
contracts and operating profitably under a capitated reimbursement system, (iv)
allowing physicians greater access to managed care, while relieving physicians
of some of the administrative responsibilities and economic risks of providing
managed care services, (v) 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 (vi) expanding
aggressively by recruiting additional physicians to networks that have already
been established, by establishing additional networks, and by transitioning
existing fee-for-service patients in physician practices to the Company's Global
Capitated Contracts. See "Business -- Strategy."

                                  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 in
February of 1995. Accordingly, the Company has a limited operating history. For
the year ended December 31, 1995, the Company recorded a net loss of $3,180,723.
The Company is likely to record a net loss for the year ending December 31, 1996
and at March 31, 1996 had an accumulated deficit of $5,018,540. There can be no
assurance that the operating losses incurred by the Company will not exceed
those that are presently expected or that the Company will be able fully to
finance working capital and practice acquisition requirements. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Results of Operations."
    
 
LIQUIDITY; RESTRICTIONS ON FINANCING
 
   
     Although the Company believes that its available working capital, together
with a banking facility under negotiation, will be sufficient to meet the
Company's anticipated needs for cash to conduct operations through June 30,
1997, there can be no assurance that the terms of the facility being negotiated
will be agreed to and finalized or will be on terms favorable or acceptable to
the Company. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital Resources."
    
 
   
     Further, the holders of the Company's Series A and Series B Preferred Stock
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 impacted by certain rights of consent of the holders of the
Company's Series A and Series B Preferred Stock. See "Description of Capital
Stock." Thus, the Company may be unable to obtain sufficient financing to
continue its operations in the event that its operating losses exceed
expectations by a significant amount. In the event that the Company is able to
obtain additional financing, no assurances can be given that the terms of such
financings, if any, would be favorable to the Company.
    
 
UNCERTAINTY OF STRATEGY; ACQUISITION RISKS
 
   
     While the Company has developed a strategy and has negotiated a number of
commercial relationships with PCPs, IPAs, specialist physicians, hospitals and
Managed Care Payors, the Company's strategy is based upon a number of
assumptions (including, without limitation, assumptions relating to the
Company's likely rate of growth, the rate at which capitated lives can be added
to the Company's network of Affiliated Physicians, the likely referral and other
business practices of physicians and health care institutions in the Maryland
market area and beyond, 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 may materially and adversely affect the Company's business.
Thus, no assurance can be given that the Company's strategy will be successfully
and profitably implemented.
    
 
   
     Further, the Company's strategy is premised upon the successful execution
of acquisition transactions of Core Medical Groups and affiliation transactions
with 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 affiliates. The process of identifying suitable acquisition
and affiliation candidates, and proposing, negotiating and implementing an
economically feasible affiliation with a physician group or forming or managing
of a physician network, is lengthy and complex. Further, substantially all of
the Company's net revenues generated by the medical practices acquired by or
affiliating with the Company will be used to pay for costs of providing medical
care. Thus, the Company's ability to generate any profit is dependent upon its
ability to move its Affiliated Physicians and other providers in the Company's
provider networks away from an unmanaged fee-for-service compensation
arrangements and into a profitable managed care, or capitated, environment. In
addition, the Company's financial results are negatively affected to the extent
that the start-up costs associated with developing practices do not immediately
translate into revenues. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
    
 
                                       6
 
<PAGE>
DEPENDENCE ON MANAGED CARE CONTRACTS
 
   
     The profitability of the Company depends on securing managed care contracts
and successfully managing the expenses involved in the provision of services
under those contracts by its Affiliated Physicians without sacrificing the
quality of medical care. Although the Company attempts to manage expenses
through negotiation of favorable contracts based upon utilization that is driven
by prudent protocols developed by the Company and the Core Medical Groups to
ensure high quality and cost effective care, such expenses are not otherwise
within the Company's or the Core Medical Groups' control, and are subject to
adverse selection and other utilization risks. The inability of the Company and
its Affiliated PCPs to obtain such contracts or successfully to manage such
expenses would materially and adversely affect the Company's earnings and
revenues. In addition, the success of managed care 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 the numbers of managed care contracts presently contemplated
or that, if such contracts are obtained, payments from such managed care payors
will decrease over time, causing an adverse effect on the Company's earnings and
revenues. Finally, the Company's contracts with payors, which contracts
generally are for one to three year terms, may be terminated earlier upon
notice. There can be no assurance that such payor contracts will not be
terminated. The loss of any payors or the failure to regain or retain such
payors' enrollees could have a material adverse effect on 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 results of operations are highly dependent on the
Company's ability to enroll existing patients and new Medicare patients in the
Company's Medicare managed care contracts with licensed HMOs. See
"Business -- Strategy -- Medicare Managed Care." The Company's strategy for
enrolling Medicare patients in managed care plans 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 enroll a sufficient number of Medicare
patients to its Medicare managed care plans or that such patients can be
converted in accordance with the Company's business plan. The failure of the
Company to enroll a sufficient number of Medicare patients to Medicare managed
care plans could have a material adverse effect on the Company's revenues.
    
 
   
     The Company's success is also subject to various state and federal
regulations and the continuation of current reimbursement rates by the federal
government under the Medicare program. There can be no assurance that Medicare
reimbursement rates will remain at current levels. Substantial reduction in
Medicare capitation rates could have a material adverse effect on the Company's
financial results and profitability.
    
 
   
DEPENDENCE OF THE COMPANY ON CORE MEDICAL GROUPS AND IPAS
    
 
   
     The Company has business relationships with several primary medical care
provider groups referred to herein as Core Medical Groups. The Company does not
engage in the practice of medicine and will be largely dependent upon medical
services provided by or through the Core Medical Groups and affiliated IPAs for
its revenues. The success of the Company initially will be dependent in large
part upon its ability to attract PCPs and specialist physicians to join Core
Medical Groups or to participate in IPA arrangements with the Company, and upon
the Core Medical Groups' and PCPs' and specialist physicians' ability to perform
their obligations and 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.
    
 
   
     Typically, a PSO Agreement obligates the Core Medical Groups 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 "Development of Integrated
Health Care Delivery System -- Affiliation of the Core Medical Group and the
Company." 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 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
 
                                       7

<PAGE>
   
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
(management service organizations) 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 will 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.
    
 
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 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.
    

     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 vendors who will
become stockholders of the Company, and thus the revenues of the Company and the
level of dilution of percentage ownership interests of existing stockholders,
may be more or less than presently anticipated.
 
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 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. Further, the Company must obtain the consent of the holders of the
Company's Series A and Series B 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 may 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; PENNY STOCK RULES
 
   
     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. If either of the Common Stock or
the Options are not traded on an exchange or quoted on NASDAQ and its trading
price falls below $5 per share, it could become 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 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
    

                                       8

<PAGE>
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
   
     The executive officers and directors of the Company beneficially own
significant percentages of the various classes of the Company's equity
Securities. Accordingly, if they were to act in concert, they may be able to
control the Company's Board of Directors, and therefore, the business, policies
and affairs of the Company. See "Principal Stockholders."
    
POTENTIAL CONFLICTS OF INTEREST

   
     Certain conflicts of interest are inherent in the structure of the Company
and its contractual and organizational relationships. For example, Scott M.
Rifkin, M.D., Alan L. Kimmel, M.D., who are Directors, officers and stockholders
of the Company, and Peter J. LoPresti, D.O. and Robert Ancona, M.D., currently
Directors of the Company, are also members of Baltimore Medical Group, LLC, and
are stockholders, officers and directors of BMGGP, Inc., the general partner of
MHLP. Further, D. Alexander Rocha, M.D., and William D. Lamm, M.D., both
Directors of the Company, are also the respective Chairmen of Carroll Medical
Group and Cumberland Valley Medical Group. From time to time, the interests of
such persons may conflict with those of the Company due to such relationships.
See also the discussion in "Certain Transactions."
    

DIVIDENDS
   
     Dividends on the Securities are not contemplated in the foreseeable future
because the shares of Common Stock of the Company are subordinated as to
dividends to the Preferred Stock, the Preferred Stock provisions prohibit the
payment of dividends without the consent of the holders of the Preferred Stock,
and because it is expected that the Company's earnings, if any, will be retained
for working capital and expansion.
    
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 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
transactions described generally herein, including those by or with the Core
Medical Groups and its employee physicians, IPAs and other affiliated physicians
and providers are subject to extensive and pervasive Federal and state
regulation pursuant to currently effective 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. While management of the Company intends to develop its
operations in a manner that does not subject the Company to regulation by the
Maryland Insurance Commission, there can be no assurance that such efforts will
be successful. Regulation which affects the IPAs, Core Medical Groups, hospitals
and other providers of health care may also have a significant effect on 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 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
    

                                       9

<PAGE>
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 upon the Company.

     The Company's physician networks contract with physicians and other health
care professionals as independent contractors and, in accordance with federal
and state tax guidelines pertaining to independent contractors, do not withhold
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 Company's operating results.
 
     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
will not be adversely affected by changes in applicable laws, regulations or
interpretations thereof.
 
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.
    
 
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, its affiliated health care providers and other entities with
which it contracts are subject to the United States and State 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 and such
affiliates 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 and business plan
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 and the Federal Trade Commission. 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
affiliation of medical practices with the Company. In such event, the Company
expects to receive certain assets of such practices or capital stock of the
relevant medical practice, or as well as certain contractual rights. The Company
will not receive cash proceeds in connection with the issuance of the
Securities.
    

   
                      SELECTED CONSOLIDATED FINANCIAL DATA

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   
GENERAL
    
 
   
     The Company was incorporated in June 1994, but it did not receive initial
funding until February 1995. Prior to that date, the Company was in a formative
stage, acquiring capital, developing its internal systems and recruiting
management personnel. Operations from the Company's inception through December
31, 1994, were insignificant. Accordingly, no results are presented for the
period from the Company's inception in June 1994 through December 31, 1994.
Through March 31, 1996, the Company had acquired certain assets of 43 primary
care physician practices. As a result of the Company's limited period of
affiliation with the practices, the Company does not believe that period to
period comparison and percentage relationships within the periods set forth
below are meaningful.
    
 
   
     The Company has acquired, at net book value, the furniture, fixtures and
equipment, and at net realizable value, the accounts receivable, of certain
medical practices. At the time of such acquisition, the physician has entered
into a 10-year employment agreement with a Core Medical Group. Further, each
Core Medical Group has entered into long-term management service agreements with
the Company (PSO Agreements), 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.
    
 
   
     The Company's acquisitions of certain assets of physician practices are
subject to reacquisition rights whereby the physicians may rescind the
transaction typically within a nine month period from the date of closing. As of
March 31, 1996, of the 43 primary care physicians that sold certain of their
assets to the Company, 20 physicians had such rights still available. All of the
agreements contain provisions requiring the Affiliated Physicians to repurchase
substantially all of the assets previously acquired at the price paid by the
Company at the closing. To date, one physician has 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
affect on the Company in light of the Company's experience. Management does not
believe that there will be substantial rescissions of physician affiliation
transactions. For the three months ended March 31, 1996, physicians with
reacquisition rights represented approximately $516,983 or 19.8% of the
Company's total net physician billings of $2,611,574 for the period then ended.
In the event some or all of these physicians exercised their rights, the Company
believes that such exercises would not have a material adverse effect on the
Company.
    
 
   
     The Company currently derives net revenues primarily from direct patient
and third party billing for medical services provided by affiliated physicians
within the Core Medical Groups. 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, Medicaid) and private insurance carriers. The Company derives
little or no earnings from these revenue sources as the proceeds from such
revenues are paid to the Core Medical Group for the accounts of the Affiliated
Physicians. The Company's profitability depends on securing Global Capitated
Contracts and successfully managing the revenues obtained per capitated patient
so that expenses involved in the delivery of medical services by its Affiliated
Physicians and other providers are less than such revenue. The inability of the
Company to obtain such contracts, to attract patients to participate in such
contracts, or to successfully manage the cost of care would materially and
adversely affect the Company's revenues and primary source of earnings.
    
 
   
     The Company's success under these capitation contracts depends upon the
overall health of its Enrollees, its ability to manage appropriate and timely
utilization of medical resources, and its ability to conclude favorable
agreements with payors and other health care providers. To the extent that the
Enrollees covered under a capitated fee contract require more frequent or
extensive care than was anticipated by the Company, the revenue to the Company
under the contract may be insufficient to cover the cost of care provided.
    
 
   
     For the year ended December 31, 1995, the Company derived 61% of its net
revenues from direct patient and third party billing (fee-for-service), 30% from
government sponsored healthcare programs (including Medicare) and 9% from
Gatekeeper Capitation Contracts. For the three months ended March 31, 1996, 60%
of revenues were generated from direct patient and third party billing, 30% from
government sponsored healthcare programs, 8% from Gatekeeper Capitation
Contracts, and 1% from Global Capitation Contracts. The Company's consolidated
results of operations reflect revenues generated by the Core Medical Groups and
the costs associated with the delivery of their services, including physician
salaries, benefits, malpractice insurance and corporate expenses. Currently, the
Company is working with payors to enroll fee-for-service commercial and Medicare
patients to the Company's Global Capitated Contracts, but as of March 31, 1996
had not
    
 
                                       12
 
<PAGE>
   
enrolled a sufficient number of such patients to cover the Company's operating
costs. To the extent the Company is unable to enroll patients in the Company's
Global Capitated Contracts in adequate numbers to cover operating costs, it will
have a material adverse affect on the Company's ability to generate sufficient
revenues to cover its normal and necessary expenses.
    
 
   
     The Company's operating results are significantly impacted by the number of
Affiliated PCPs. From February 24, 1995 to March 31, 1996, the number of PCPs
who sold certain of their assets to the Company and affiliated with a Core
Medical Group increased from 18 to 43. During the same period of time, the
Company entered into three Global Capitated Contracts.

     When affiliating with the physician, the Company, through each PSO
Agreement and such physician's employment with the Core Medical Group, acquires
the exclusive right to negotiate Global Capitated Contracts on behalf of the
physician. In addition to the consideration paid in acquiring certain tangible
assets, leaseholds and contract rights, all direct costs associated with the
acquisition are capitalized. The increase in the number of PCP's has contributed
to the increase in revenue growth as well as increase in operating costs to
support the physician growth.
    
 
   
RESULTS OF OPERATIONS
    
 
   
YEAR ENDED DECEMBER 31, 1995 AND THREE MONTHS ENDED MARCH 31, 1996
    
 
   
     For the year ended December 31, 1995, net revenues were $4.9 million. For
the three months ended March 31, 1996, net revenues were $3.1 million. Net
physician billings (consisting of billings from fee for service arrangements and
ancillary services, less contractual allowances) constituted $4.1 million or
83.5% of net revenues for the year ended December 31, 1995. For the three months
ended March 31, 1996, net physician billings were $2.6 million or 83.9% of net
revenues. Capitated gatekeeper income was $600,000, or 12.2% of net revenues for
the year ended December 31, 1995. For the three months ended March 31, 1996,
capitated gatekeeper income was $340,000 or 10.9% of net revenues. The Company
had no global capitated contractual income for the year ended December 31, 1995.
For the three months ended March 31, 1996, global capitated contractual income
was $106,000 or 3.4% of net revenues. Interest and other income was $211,000, or
4.3% of net revenues for the year ended December 31, 1995. For the three months
ended March 31, 1996, interest and other income was $51,000 or 1.7% of net
revenues. During the year ended December 31, 1995, the Company affiliated with
31 physicians. The Company affiliated with an additional 12 physicians during
the three months ended March 31, 1996. During the three months ended March 31,
1996 the Company began enrolling capitated lives under capitated contracts.
    
 
   
     For the year ended December 31, 1995, expenses associated with contracted
physician services (physician compensation) were $2,033,186, or 41.4% of net
revenues. For the three months ended March 31, 1996, expenses associated with
contracted physician services were $1,097,408 or 35.3% of net revenues. Care
center costs for the year ended December 31, 1995, were $2,830,685, or 57.6% of
net revenues. For the three months ended March 31, 1996, care center $1,464,042
or 47.1% of net revenues. General and administrative expenses for the year ended
December 31, 1995, were $1,314,163, or 26.7% of net revenues. For the three
months ended March 31, 1996, general and administrative expenses were $551,501
or 17.7% of net revenues. Corporate salaries and benefits for the year ended
December 31, 1995 were $1,624,436, or 33% of net revenues, while interest
expenses during the period (consisting primarily of interest on notes payable to
physicians) were $129,038, or 2.6% of net revenues. For the three months ended
March 31, 1996, corporate salaries and benefits were $1,026,597 or 33% of net
revenues, while interest expenses were $112,088 or 3.6% of net revenues.
Depreciation and amortization for the year ended December 31, 1995, was $165,926
or 3.4% of net revenues, and for the three months ended March 31, 1996 were
$82,229 or 2.6% of net revenues.
    
 
   
     For the year ended December 31, 1995, and the three months ended March 31,
1996, corporate costs (consisting of general administration, salaries and
benefits, depreciation and amortization and interest expense) exceeded revenues
due to
    
 
                                       13

<PAGE>
   
the formative nature of the Company. The Company is devoting significant
resources to establishing its infrastructure, investing in contractual
relations, procuring provider risk-sharing arrangements including Global
Capitation Contracts and establishing an integrated health care delivery system.
    

   
     The Company entered into three Global Capitation Contracts during the three
months ended March 31, 1996. The Company works with payors to enroll a
substantial number of fee-for-service commercial and Medicare patients in global
capitation plans. At March 31, 1996, the Company had approximately 500 covered
lives under management in its Global Capitated Contracts. However, the Company
has not obtained a sufficient number of lives under Global Capitated Contracts
to generate sufficient revenues to cover the Company's operating costs as of
March 31, 1996. The Company did not generate adequate cash to fund operations
for the year ended December 31, 1995, and for the three months ended March 31,
1996. The Company has working capital, a note receivable and an existing bank
credit facility to assist in funding anticipated operations. See "Liquidity and
Capital Resources." Although contracted physician services, care center costs
and corporate costs are expected to increase at a lesser rate than the increase
in net revenues, the Company is likely to report a use of cash from operations
and expects to record a net loss for the year ending December 31, 1996. See
"Risk Factors -- Losses; Restrictions on Financing."
    
 
   
     The Company's results of operations for the future are subject to certain
trends and uncertainties that may have an adverse impact on the Company. As
described in "Risk Factors -- Uncertainty of Strategy; Acquisition Risks," while
the Company has developed a strategy and has negotiated a number of commercial
relationships, the Company's strategy is based upon a number of assumptions, and
there can be no assurance that the Company's strategy will be successfully
implemented. As described in "Risk Factors -- Losses, Restrictions on
Financing," substantially all of the Company's net revenues generated by
transactions between the Company and Affiliated PCPs will be used to fund
physician salaries and to pay for other care center costs. As described in
"Business -- Overview of Business Activities," the ability of the Company to
achieve and maintain profitability will depend to a great degree on the
negotiation of compensation arrangements under Global Capitated Contracts that
result in payments to the Company that exceed the payments by the Company to
PCPs and other health care providers in a managed care environment. Accordingly,
there can be no assurance as to when the Company will achieve profitability.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     On February 24, 1995, the Company issued $5 million of Series A Preferred
Stock in exchange for $2 million in cash and a $3 million subscription
receivable evidenced by a note (the "Series A Note"). The Company used the $2
million at closing to fund the formation of the Company, to acquire certain
assets of the 18 primary care physicians, and to initiate implementation of its
business strategy. During the fourth quarter of 1995, the Company drew down
$500,000 on the Series A Note to fund physician acquisitions, infrastructure
development and corporate costs.
    
 
   
     On December 1, 1995, the Company issued Series B Preferred Stock for $4
million and issued warrants for the guarantee of the Company's bank credit
facility by the holder of the Series B Preferred Stock. The funds were used for
the acquisition of physician practices, development of the Company's information
systems and corporate expenses in conjunction with its business strategy.
    
 
   
     The Company requires capital to acquire the assets of recruited physician
practices, and to develop and install the information systems necessary for the
management of provider risk-sharing contracts, including global capitation
contracts, and for billing and collection services. Global Capitation Contracts
positively impact the Company's cash flow due to the fact that the Company
receives capitation revenue prior to incurring costs associated with services
provided under such contracts.
    
 
   
     The Company's principal uses of cash have been for acquisition of certain
assets of physician practices, and the purchase of property and equipment
including the development of its information systems and operating activities.
For the three months ended March 31, 1996, the Company's operating activities
used cash of $3.2 million. Cash used for operating activities for the year
ending December 31, 1995 was $2.4 million. Net cash used in investing activities
for the three months ended March 31, 1996 was $459,000 and for the year ended
December 31, 1995 was $881,000. The use of cash for investing activities relates
primarily to the acquisition of furniture, fixtures, and equipment, and the
purchase of the physicians' assets and the information systems necessary for the
management of provider risk-sharing contracts and billing and collection
activities. Net cash provided by financing activities for the three months ended
March 31, 1996, was $957,000. For the year ended December 31, 1995, net cash
provided by financing activities was $6.1 million, and consisted primarily of
the cash proceeds from the issuance of the Series A and Series B Preferred
Stock.
    

                                       14
 
<PAGE>
   
     At March 31, 1996, the Company had working capital and available credit
facilities (including $2.5 million remaining payable on the Series A Note) of
approximately $3.75 million, including cash and cash equivalents of
approximately $177,000. For the year ended December 31, 1995, the Company had
working capital and available credit facilities of $9.2 million. Accounts
receivable were $961,000 at December 31, 1995, and were $2,361,000 at March 31,
1996. This increase of $1.4 million is attributable to the acquisition of
physician receivables and increased net revenues.
    

   
     On December 1, 1995, the Company entered into an agreement (the "Bank
Credit Facility Agreement") with NationsBank of Maryland, N.A. ("NationsBank")
as agent, which provides for a revolving bank credit facility (the "Bank Credit
Facility"). The maximum availability under the Bank Credit Facility is $4
million, which the Company can use for recruitment of physicians, operating
expenses and anticipated capital acquisitions. At June 1, 1996 there was
approximately $3.0 million outstanding under the Bank Credit Facility. Advances
under the Bank Credit Facility bear interest at the Company's option at either
NationsBank's prime rate or the Eurodollar rate plus .75%. The Bank 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 Bank Credit Facility are guaranteed by the
Company's Series B Preferred Stockholder (Med-Lantic Management Services, Inc.).
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 Physician Services Organization Agreements between the
Company and Core Medical Groups. Upon redemption of the Series B Preferred Stock
in connection with issuance of junior preferred stock to a holder whose
interests are deemed adverse to the guarantor, the Company is required to obtain
a release of the guarantee.
    
 
   
     The Company may draw down on the unfunded portion of the Series A Note,
which was $2.5 million as of the date of this Prospectus. The Series A Note
bears interest at 6.5% per annum. Interest is payable only to the extent that
the Company pays dividends on the Series A Preferred Stock.
    
   
     Scheduled payments on the Series A Note are subject to deferral at the
Company's option until February 24, 1998, although interest continues to accrue
on any unpaid balance. As of March 31, 1996, the Company had elected to defer
$1,250,000 of scheduled draws under the Series A Note compared to deferral of
$750,000 at December 31, 1995. Upon redemption or conversion of the Series A
Preferred Stock, any unpaid principal is to be canceled in an amount equal to
five times the number of shares redeemed or converted. The Company has the
option to require payment of any outstanding principal and interest on February
24, 1998, or the Company may elect to redeem the outstanding Series A Preferred
Stock and cancel the remaining principal and interest.
    
   
     Until the Company enrolls an adequate number of capitated patients in
Global Capitated Contracts, the Company expects to incur operating losses and
experience negative cash flows through the end of 1996. As a consequence, in
order to meet the Company's working capital requirements to fund operations the
Company will need to conclude an anticipated banking facility. The Company is
currently in negotiations with several commercial lenders for a facility, the
principal amount of which is expected to be not less than $24 million. Although
the Company believes it will be able to obtain such a facility on terms that
will satisfy the Company's requirements, there can be no assurance that the
banking facility will be agreed to and finalized or that it will be on terms
favorable or acceptable to the Company.
    

   
     The Company's ability to incur indebtedness is subject to the consent of
the holders of the Series A and Series B Preferred Stock under certain
circumstances. See "Description of Capital Stock."
    

   
     The Company intends to conduct operations in accordance with its business
strategy, including recruitment of primary care practices fund operating
expenses with its existing cash and cash equivalents, and borrowings under the
Bank Credit Facility note receivable, and anticipated banking facility. The
Company believes that these sources of working capital will be sufficient to
meet the Company's anticipated needs through June 30, 1997.
    
 
   
     Although the Company does not have material commitments for capital
expenditures, the Company may make additional capital expenditures in connection
with its business strategy and development of its integrated delivery system.

INDUSTRY
 
   
     The Health Care Financing Administration 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 inflation. 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 49.0 million in 1993, a 14.6% compound
annual growth rate. According to industry sources, there are over 600 HMOs
currently operating in the United States, covering approximately 17% 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. The physician practice
management market is estimated at $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 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 most 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 physicians have exceeded significantly 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 and affiliated IPAs and related networks based upon PCPs 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 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 risk contracts with HMOs and other payors that will enable the Company
to derive revenues by encouraging preventive medicine and by the appropriate
utilization of medical resources. The key elements of this strategy are as
follows:
    
 
     INTEGRATE HEALTH CARE PROVIDERS INTO COMPREHENSIVE NETWORKS. The Company
develops and consolidates individual or groups of PCPs, specialists, hospitals
and other providers into primary care-driven comprehensive health care networks,
permitting it to assume risk capitation contracts for certain health care
services. The Company intends that physicians will
 
                                       16
 
<PAGE>
   
participate through employment or other contractual relationships with the
Company and its affiliates, while the Company will negotiate favorable rates, to
the extent feasible, from hospitals and other providers. All participants will
agree to follow the Company's PCP-driven clinical protocols and procedures, and
will be closely supervised by the affiliated PCPs. The Company believes that its
health care delivery networks (i) will provide physicians with greater access to
managed care contracts by facilitating contractual relationships with multiple
HMOs or other payors, (ii) can establish a single point of entry into an
integrated health care delivery network for HMOs and other payors, and (iii)
will offer patients a comprehensive range of high quality medical care.
    
 
     ATTRACTIVE TO PHYSICIANS. A key component of the Company's strategy is to
be attractive to physicians, and particularly to PCPs. The Company is dedicated
to the creation of professionally managed networks that grant physicians broad
clinical autonomy, practice office independence, 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 capitation contracts, with each of
the HMO payors in a region in which affiliated PCPs 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 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. The Health Care
Financing Administration estimates that there are approximately 325,000 Medicare
recipients in the greater Baltimore area and that only approximately 9,000 are
currently enrolled in HMOs. The Company's results of operations are highly
dependent on its ability to enroll its present portion of affiliated physicians'
current Medicare fee-for-service patients to Medicare managed care plans and
attracting new Medicare patients that enroll in Medicare HMOs with whom the
Company contracts.
    
 
   
     The Company currently has two Medicare Global Capitated Contracts with CFS
Health Group and 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 an Affiliated PCP. The
Company's strategy depends to a great extent on its success in having its PCP's
current Medicare patients convert from the traditional Medicare fee-for-service
program to one of the Medicare managed care plans that provide for capitation
payments to the Company. For the Medicare patients enrolled in the plans with an
Affiliated PCP, the Company 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 and appropriate specialty care and
closer affiliation with fewer specialists who will benefit from increased
referrals at lower rates, (iii) to reduce 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 and
its Affiliated Physicians believe 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,
    
 
                                       17
 
<PAGE>
   
and excessive utilization of high cost services. The Company believes that lower
cost, more appropriate care is both preferable to the patient and less expensive
to the payor.
    
 
   
     EXPANSION STRATEGY. The Company's growth strategy is based upon actively
developing or consolidating 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, (iii) contracting with payors to
expand the number of capitated lives within existing physician practices, and
(iv) expand coverage of existing patients by HMOs.
    
 
HISTORY OF THE COMPANY
 
   
     INITIAL ACQUISITION TRANSACTION. The Company was incorporated in June 1994
and commenced operations in February 1995 when it organized Baltimore Medical
Group, LLC, as its initial Core Medical Group, and acquired certain assets of 18
primary care physician practices. Upon Baltimore Medical Group, LLC's formation
in February 1995, it acquired certain laboratory assets and accounts receivable
from Baltimore Medical Group, P.A., a company which was formed in January 1993
by five of the initial 18 primary care practices, including those of Drs.
Rifkin, Kimmel and Ancona. Subsequently, one of the 18 initial PCPs exercised
his reacquisition rights. Scott Rifkin, M.D., Alan Kimmel, M.D., David Nagel,
M.D., and Robert Ancona, M.D., four of the original members of Baltimore Medical
Group, LLC, are currently directors of the Company.
    
 
   
     The Company acquired the PCPs' assets through Medical Holdings Limited
Partnership, a Maryland limited partnership ("MHLP"). In February 1995, at the
time of the establishment of Baltimore Medical Group, LLC, MHLP was formed and
the Baltimore Medical Group physicians transferred certain medical practice
assets, excluding laboratory and other ancillary assets, to MHLP in exchange for
limited partnership interests in MHLP, cash and promissory notes. The laboratory
and other ancillary assets were transferred to Baltimore Medical Group, LLC by
Baltimore Medical Group, P.A. 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. At
the time the Company acquired certain practice assets, the initial physician
owners became members and employees of Baltimore Medical Group, LLC, and have
continued the practice of medicine 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 -- Affiliation of the Core Medical Group
with the Company."
    
 
   
     Under the Partnership Agreement of 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, 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 establishment of Baltimore Medical Group, LLC, and MHLP,
additional physicians have sold certain assets of their medical practices and
acquired limited partnership interests in MHLP and membership interests in
Baltimore Medical Group, LLC, Carroll Medical Group, LLC, and Cumberland Valley
Medical Group, LLC. In addition, they have become employees of these Core
Medical Groups. In several instances, physicians who affiliated with the Company
received shares of the Company's Class B Common Stock directly in lieu of
partnership interests in MHLP. Other physicians have become affiliated with the
Company through other Core Medical Groups, such as Carroll Medical Group.

     The Company is seeking to construct its integrated delivery system by
acquiring the assets of medical practices throughout the Baltimore-Washington
and other regions.
    
 
   
     EXPANSION INTO CARROLL COUNTY, MARYLAND. In November 1995, the Company
affiliated with 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.
    
 
   
     EXPANSION INTO MONTGOMERY COUNTY, MARYLAND. In February 1996, the Company
entered into letters of intent to acquire the assets of primary care practices
of 22 physicians in Montgomery County, Maryland. The Company expects to
consummate these transactions in June 1996.
    
 
   
     EXPANSION INTO ANNE ARUNDEL COUNTY, MARYLAND. In February 1996, the Company
entered into letters of intent to acquire the assets of primary care practices
of nine physicians in Anne Arundel County, Maryland. The Company expects to
consummate these transactions in June 1996.
    

   
     EXPANSION INTO ALLEGANY COUNTY, MARYLAND. In May 1996, the Company
consummated the acquisition of the assets 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
Baltimore Medical Group, LLC, CVMG entered into a PSO Agreement with the
Company. The Company is establishing an IPA in Allegany County.
    
 
   
     EXPANSION INTO WASHINGTON COUNTY, MARYLAND. The Company is establishing an
exclusive Managed Care contracting arrangement with an IPA representing
approximately 25 primary care physicians in Washington County, Maryland.
Pursuant to the Exclusive IPA agreement, the Company will negotiate Managed Care
contracts on behalf of the IPA PCPs.
    
 
   
     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.
    
 
   
     The Company expects its affiliation activities to continue by increasing
the number of physicians in each Core Medical Group, forming new Core Medical
Groups, and pursuing acquisition and expansion opportunities throughout the
state of Maryland and surrounding regions.
    

OVERVIEW OF BUSINESS ACTIVITIES
 
   
     The Company's integrated healthcare delivery system includes PCPs who
affiliate with the Company through the transfer of certain assets of the
physician's practice to the Company and the employment of the physician with a
Core Medical Group such as Baltimore Medical Group. PCPs may also affiliate with
the Company through participation in an Independent Practice Association
("IPA"). A PCP who becomes employed by a Core Medical Group agrees to conduct
his medical practice only through the 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, that 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 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 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 the

                                       20
 
<PAGE>
   
negotiation of compensation arrangements that result in payments to the Company
that exceed the cost of care by the Company to 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 specialists,
hospitals and other health care providers, creating economic incentives for all
affiliated providers 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.
    
 
   
     Under managed care capitated contracts with payors, the Company expects to
derive revenues from the management of patient care costs for specialist and
hospital services. The Company pays its PCPs a primary care capitation amount
based on the geographic market in which the PCP operates from the capitation
payment received from the HMO. The Company also contracts with other providers,
such as specialist and hospital and ancillary services providers.
    
 
   
     The Company intends to finance 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 network may derive benefit from
the successful implementation of the Company's strategy in several ways. A
physician to whom equity 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 his affiliation with the Company involves becoming 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 participating PCPs and other physicians. See
" -- Affiliation of the Core Medical Groups and the Company" and "Affiliation
through IPAs."
    
 
   
     As of May 1996, there were approximately 140 PCPs, 93
obstetrician-gynecologists and 390 specialty physicians who had transferred
their practice assets or otherwise become affiliated by contract with the
Company and its affiliated Core Medical Groups and IPAs, or who had entered into
binding letters of intent agreeing to become so affiliated. Approximately 80 of
such PCPs had transferred, or entered into binding letters of intent to convey
certain assets of their practices to DHS affiliates and become employees of Core
Medical Groups. As of such time, the 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
physician affiliation 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 practices, negotiating and implementing 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 affiliated PCP practices. Beginning in February 1995
with respect to Baltimore Medical Group, December 1995 with respect to Carroll
Medical, and May 1995 with respect to Cumberland Valley Medical Group, 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 maintains contracts on the physicians' behalf when they
affiliate with the Company under the same 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 and USA Health
Network.
    
   
     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 Maryland. 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, 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").
    
 
                                       21
 
<PAGE>
   
     In February 1996, the Company entered into a 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. These rates are derived from historical
fee-for-service unmanaged Medicare expenses and are adjusted (and paid to the
Company) for each county.
    
   
     In May 1996, the Company entered into a Medicare Risk Service Agreement
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 age, sex and Medicare eligibility of
the subscribers enrolled with an Affiliated 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 June 1, 1996, the Company had approximately 500 Medicare and
commercial capitated lives. See "Risk Factors -- Enrollment in Medicare Managed
Care Plans." As of June 1, 1996, the Company's Affiliated PCPs provided medical
care for approximately 30,000 commercially managed care plan enrollees on a
primary care only basis. Management believes that approximately 30,000 to 40,000
additional patients of Affiliated PCPs are currently Medicare subscribers, and
the Company has developed 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
larger Core Medical Groups and/or developing a network of preferred provider
specialists who are paid on a discounted fee-for-service or capitated basis. As
of June 1, 1996, the Company had access to approximately 390 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 a capitated payment arrangement with Womancare IPA, a
Company-developed network of 93 physicians providing OB/GYN services, Advanced
Medical Imaging for radiology services, and Corning Metpath for laboratory
services. Under the Company's Network Participation Agreement with the
respective specialty network, the participating specialist providers provide
services to the Company's members referred by a Company PCP, 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. In addition, the
Company has installed 28 computer systems in 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. Through April 30, 1996, the Company had assumed
responsibility for the billing operations of 29 PCP practices, representing 45
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
 
  AFFILIATION WITH PHYSICIANS
 
   
     The Company typically affiliates with PCPs and other physicians in one of
several ways: (1) through the transfer of certain of the medical practice assets
and contracts to the Company or to a Company affiliate, as a result of which the
physician may obtain, directly or indirectly, cash and/or an equity interest in
the Company ("Investor Physicians"); (2) through an exclusive IPA arrangement,
pursuant to which such physician agrees to conduct all managed care contracting
activity exclusively through the Company and its affiliates and to take as
patients any capitated patient referred by the Company up to a certain level (an
"Exclusive IPA"), or (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 (a "Non-Exclusive
    
 
                                       22
 
<PAGE>
   
IPA"), 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. Prior to the filing of the Registration Statement, of
which this Prospectus is a part, PCPs transferred their assets to MHLP, which
then transferred the assets to the Company. Currently, the Company and/or a Core
Medical Group will acquire the assets of the medical practice directly.
    
 
     The Company also affiliates 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 with which the
Company is affiliating, the type of practice in which such physicians are
engaged, the geographic location of the practice, financial considerations,
regulatory concerns, and pre-existing contracts.
 
   
  AFFILIATED PHYSICIANS
    
 
   
     Consistent with the Company's primary care-driven strategy, the primary
focus of the Company's affiliations with physicians has been on direct or
indirect affiliation by PCPs with the Company. Since the Company's inception and
in connection with the affiliation of the physicians' medical practices with the
Company, entities (referred to herein as "Core Medical Groups") have been formed
or consolidated to conduct group medical practices. Each Core Medical Group is
comprised of a group of physicians under common management and with a common
information system and provider number, and are 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 Maryland using a limited liability
company organizational structure.
    

   
     In February of 1995, the Company acquired certain assets of the 18 PCP
practices of Baltimore Medical Group, LLC. From February of 1995 to December 31,
1995, the Company assumed exclusive management responsibility for and became the
sole contracting entity for an additional 14 PCP practices through Baltimore
Medical Group, LLC, and Carroll Medical Group for a total of 31 PCP practices.
From December 31, 1995 through February 29, 1996, the Company assumed, or
entered into letters of intent to acquire certain assets and became the sole
contracting entity for an additional 49 PCP practices. Thus, as of February of
1996, a total of approximately 80 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 practice assets 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 Affiliated
Physicians who is a member of such Core Medical Group, pursuant to which the
following transactions occur:
    
 
   
     TRANSFER BY AFFILIATED PHYSICIANS OF THE MEDICAL PRACTICE ASSETS. Under the
Transfer Agreement, each Affiliated 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 Affiliated 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." Although the amount and type of consideration payable to each Affiliated
Physician is determined by negotiations between such physician and the Company,
typically such transactions consist of an acquisition by the Company of certain
tangible and certain intangible assets of the medical practice, including
contract rights, and the collection by the Company of the accounts receivable of
the Affiliated Physician.
    
 
   
     EMPLOYMENT OF AFFILIATED PHYSICIANS BY THE CORE MEDICAL GROUP. Each
Investor 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 Investor 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 of Class B Common Stock. The Employment Agreement
provides for the payment of base salary and benefits and for the eligibility of
the Investor 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. An Investor 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".
    

                                       23
 
<PAGE>
   
     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. In some Core
Medical Groups the Company and the Core Medical Group may agree to guarantee all
or a portion of a base salary in return for a management or similar fee based
upon practice growth.
    
 
   
     AFFILIATION OF THE CORE MEDICAL GROUP WITH THE COMPANY. The Company
provides managed care contracting and practice management services to the Core
Medical Groups (and indirectly to the Affiliated Physicians) through 30 year PSO
Agreements (with 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 typical 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 Affiliated 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 broad 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. In addition, the Company may,
under the PSO Agreement, 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 obligate both the Core Medical
Group and its Affiliated Physicians to provide medical services at the levels of
compensation negotiated solely by the Company. The Company may also negotiate
for, and enter 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 Investor Physicians, all on terms
and for the compensation determined solely by the Company. The Company is
delegated 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 or which the Company otherwise cannot provide.
    
 
   
     A typical PSO Agreement provides that the Company will earn an amount equal
to the difference between the cash it collects on behalf of the Core Medical
Group and each of its physicians 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
Investor Physicians of the Core Medical Groups 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.
    
 
   
     It is the Company's intent to earn such amounts from Company revenues other
than PCP revenues, 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.
    
 
   
     A typical PSO Agreement provides 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 profits managed care-related attributable to the provision of health
care to the Core Medical Group's 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
profits 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
Investor Physicians." 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, and that the Core Medical Groups will therefore have
little or no net income.
    

   
     PSO Agreements typically have a term 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 or malfeasance, the
PSO Agreement can not be terminated by the Company or the Core Medical Group
absent a material uncured breach.
    
 
                                       24
 
<PAGE>
   
     OPERATION OF THE CORE MEDICAL GROUP. Each Affiliated Physician enters into
an Operating Agreement with each of the other Affiliated 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 Investor Physicians of the Core Medical Group. The Bonus
Committee also establishes, in consultation with the Company and the bonus
committees of other Core Medical Groups, practice protocols.
    
 
  AFFILIATION THROUGH INDEPENDENT PRACTICE ASSOCIATIONS
 
   
     The Company has affiliated with physicians in a variety of ways through
"Independent Practice Associations" (or "IPAs") in which physicians ("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 affiliation 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 referred by the Company. In some cases, the
Company may grant options to acquire Securities or issue Securities as
incentives for physicians to enter into Exclusive IPA Agreements. The Company
may also issue such options or Securities as compensation for the recruitment of
physicians to affiliate with the Company through Core Medical Groups or
Exclusive IPA Participation Agreements.
    
 
   
     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 collection.
    
 
     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 Company often provides an information system,
including all related hardware, software and documentation to such physician.
 
     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, which may include Securities or
options to purchase Securities, may also be payable by the Company pursuant to
the 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 or one
of its affiliates.
 
   
     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.
    

                                       25

<PAGE>
     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 affiliates 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 affiliates 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, or contractual arrangements involving reduced fee-for-fee service
or sub-capitated arrangements. Other than employment in a 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 affiliates with
hospitals ("Participant Hospitals") and other health care providers to
participate in its managed care networks. The Company envisions that most of its
arrangements with Participant Hospitals will involve "hub 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 and
through Core Medical Groups and through IPAs. The Company has a physician
recruitment staff led by one of the Company's founding physicians, a Director of
physician recruitment, recruiting assistants and other staff who participate in
physician recruiting. The Company also recruits PCPs through relationships with
current Investor Physicians, IPA Participant Physicians and other contacts. The
Company also seeks assistance from recruiting consulting arrangements. Such
recruiting consultants provide the Company with access to potential Investor
Physicians in Core Medical Groups and to potential IPA Participant Physicians in
IPAs.
    
 
MANAGED CARE CONTRACTING
 
  CONTRACTS WITH PHYSICIANS, HOSPITALS AND OTHER PROVIDERS OF HEALTH CARE
 
   
     As discussed above in " -- Affiliation of the Core Medical Group and the
Company" and " -- Affiliation Through 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 affiliated 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
technology 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 Investor 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 " -- Affiliation of the Core Medical Group and the
Company" and " -- Affiliation Through Independent Practice Association."
    
 
  CONTRACTS WITH PAYORS
 
   
     The Company enters into contracts with payors on behalf of physicians who
have affiliated with the Company through Core Medical Groups or IPAs. Global
Capitated Contracts typically obligate the Company to provide and pay for all
physician services (except for negotiated carve-outs) and, in many 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 according to Company care
protocols when applicable. The payment from a payor to the Company is typically
calculated based on the number of Members or 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 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.
 
                                       28

<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 PCPs in its networks and will
make such systems available on a uniform basis when such providers 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 Core Medical Group 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 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 affiliated 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 large number of regional primary care
physicians that have affiliated with the Company, thereby providing payors with
an extensive network of physicians to offer its enrollees. The Company also has
an increasing geographic coverage of physicians in its network with extensive
coverage in the Baltimore metropolitan area and affiliated groups (either
existing or with letters of intent) in Allegany, Carroll, Anne Arundel, Harford,
and Montgomery Counties. However, a large number of unaffiliated 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 the first established physician owned network in
Maryland and is currently the largest provider owned network 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 affiliated
physician, terms of employment arrangements, the level and extent of care
management imposed on the affiliated 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 primary care physicians and primary care strategies.
Although other entities may offer cash consideration for
    
 
                                       29
 
<PAGE>
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 provides its
affiliated 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 providers, including
administrative, legal and accounting services, billing and collection services,
referral management, utilization review, and computer systems and training,
thereby providing Affiliated PCPs more time to devote to the practice of
medicine. See "Risk Factors -- Competition."
    
EMPLOYEES

   
     As of the date of this Prospectus, the Company had 75 full-time employees
in its headquarters in Owings Mills, Maryland. The Company also employs
additional full-time and part-time office personnel in each of the Core Medical
Group physician's medical offices.
    

PROPERTIES AND ASSETS

     The Company leases approximately 24,000 square feet in Owings Mills,
Maryland for its corporate headquarters. The term of the lease continues until
2001. The Company also leases physician offices of varying sizes, generally
ranging from approximately 900 square feet to more than 5,000 square feet. The
Company anticipates that as it continues to grow, expanded facilities will be
required. The Company does not anticipate significant difficulties in obtaining
additional or new facilities.
 
     As of the date of this Prospectus, the Company's principal assets consist
of the assets of the medical practices of the Investor Physicians, computer
hardware and software, the rights granted to it pursuant to the PSO Agreements,
contractual relations with providers and payors and cash.
 
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, 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
 
                                       30
 
<PAGE>
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)7neither the patient nor the payor may be billed; (ii)7payors can recover all
amounts previously billed and paid in respect of non-excepted self-referrals;
and (iii)7the 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
Investor Physicians, as well as similar entities affiliated 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 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
    
 
                                       31
 
<PAGE>
   
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 affiliated 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 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. 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 all 200,880 options granted is $.01 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, and 198,380 options were issued
and outstanding.
    
 
                                       36
 
<PAGE>
     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 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 warrants to purchase
8,000 shares each of Class A Common Stock of the Company at an exercise price of
$11.25 per share.
    
 
  EMPLOYMENT AGREEMENTS
 
     The Company has entered into employment agreements with Messrs. Gold,
Serini and Sanders.
 
   
     Pursuant to the employment agreement with Mr. Gold, Mr. Gold receives a
1996 base salary of $200,000 per annum, a $75,000 bonus and at least 40% of the
Company's bonus pool (the "Bonus Pool"). The Bonus Pool will be equal to 10% of
the amount of the excess, if any, of operating revenues of the Company over its
operating expenses. Mr. Gold has the authority and discretion to determine
awards to be made from the remainder of the Bonus Pool to employees of the
Company, including himself. Mr. Gold also received 150,000 shares of Class A
Common Stock (currently 600,000 shares as a result of the August 1995 stock
split), in which Mr. Gold will be fully vested by May of 1996. The employment
agreement with Mr. Gold 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. Gold 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 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
standards by which such bonus will be determined for each applicable year will
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
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 Mr. Sanders, Mr. Sanders receives
a base salary of $112,500 per annum. Mr. Sanders will be entitled to participate
in the Bonus Pool to the extent determined by the Chief Executive Officer based
upon agreed upon performance standards or otherwise exemplary performance.
Pursuant to the employment agreement, Mr. Sanders received an option to purchase
22,550 shares of Class A Common Stock. Mr. Sanders may exercise such option
beginning in April 1, 1996, and will become fully vested in such options in
April of 2000, or earlier under certain circumstances. The employment agreement
with Mr. Sanders 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. Sanders 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. Mr. Sanders has given notice of his
intention to resign from the Company effective July 23, 1996.

     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.

STOCKHOLDERS AGREEMENT
 
     In December of 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") and Med-Lantic Management Services, Inc. (collectively,
the "Stockholders") entered into a Stockholders Agreement (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 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.

                              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 $302,700 payable to the Company in
connection with certain professional management services rendered in 1995 and
the first three 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 Affiliated Physicians of the Core Medical Groups affiliated with the Company.
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.
    
   
     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 $400,000 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 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 May 31, 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 May 31, 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") (the Series A Preferred Stock and the Series B 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 June 1, 1996, 800,000 shares of Class A Common Stock are issued and
outstanding and held by three holders of record, 2,398,000 shares of Class B
Common Stock are issued and outstanding and held by seven holders of record,
1,000,000 shares of Series A Preferred Stock are issued and outstanding and held
by one holder of record and 355,556 shares of Series B 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 six 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 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"). 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 or Series B Subclass, as the case may be,
shall be sufficient to elect a Converted Series A Class C or Converted Series B
Class C Director, respectively. The Series A Subclass or the Series B 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 or Converted Series B 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 Preferred Stock and Series B
Preferred Stock shall cease and terminate.
 
SERIES A AND SERIES B PREFERRED STOCK
 
     VOTING RIGHTS. Except with respect to the election and removal of
directors, every holder of Series A Preferred Stock and every holder of Series B
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.
 
                                       42

<PAGE>
     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 Preferred Director by the affirmative vote of at least 80% of all of
the votes entitled to be cast for such Series A Preferred Director.
 
     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 A Preferred Director by the affirmative vote of at least 80% of all of
the votes entitled to be cast for such Series B Preferred 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 and each of the Series B
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 or Series B Preferred Stock, as the case may be, or Class C
Common Stock, or (iii) amendments to any of the employment agreements between
the Company and a Management Stockholder.
 
     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 the Company's
business plan, (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 and the Series B Preferred Stock
must be redeemed by the Company (unless such right is waived in writing by the
holder of Preferred Stock), and 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 petition in bankruptcy, unless dismissed
within certain prescribed time periods; (iii) the default by the Company of any
obligation under certain material indebtedness which results in the acceleration
of the maturity of such indebtedness or in any action to possess any property or
assets of the Company in respect of such indebtedness; (iv) the entry of a
material judgment against the Company, which is not dismissed, stayed, or fully
bonded within 60 days; (v) the failure by the Company to pay any amount due to
the holders of the Preferred Stock when due; (vi) any failure by the Company to
perform its other material obligations in respect of the Preferred Stock which
is not cured within prescribed time periods; and (vii) certain other events,
including changes of control of various types.
 
     CONVERSION. All, but not less than all, of the shares of the 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 Preferred Stock at any time prior to 5:00 p.m.
(EST) on February 24, 2000. However, holders of the Preferred Stock who have not
made full payment in cash to the Company for the shares of Preferred Stock may
not convert their shares. Shares of Preferred Stock will automatically be
converted (unless redeemed), one share for one share (subject to
 
                                       43
 
<PAGE>
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 into shares of common
stock on 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. 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 a the rate of 9.75% per annum. 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.
 
     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
the preferential liquidation amounts to the holders of Series A Preferred Stock
and the Series B 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 holders of Series A
Preferred Stock and the holders of Series B Preferred Stock:
 
     (i) upon the payment in full of all accumulated and unpaid accrued
         dividends on all outstanding shares of Series A Preferred Stock and
         Series B Preferred Stock, redemptions of shares of Class A Common Stock
         owned by any "Management Stockholders" (Mr. Gold and Drs. Kimmel and
         Rifkin) only and to the extent required by such Management
         Stockholder's employment agreement;
 
                                       44
 
<PAGE>
     (ii) redemptions of shares of Class A Common Stock owned by any employee
          (other than a Management Stockholder) when and as approved by the
          Board or required by law or by the terms of any agreement with such
          employee;
 
     (iii) redemptions of Class B Common Stock issued by the Company to MHLP,
           until such time as there are more than 66 physicians holding limited
           partnership interests in MHLP;
 
     (iv) redemptions under any other circumstances expressly contemplated by
          the Stockholders Agreement, including any amendments thereto (see
          "Stockholders Agreement");
 
     (v) certain redemptions of Series A Preferred Stock; or
 
     (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.
 
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.
 
                                       45
 
<PAGE>
  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.
    
   
  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.
    
                                 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 sheet of Doctors
Health System, Inc. (a Maryland corporation) and Affiliates as of December 31,
1995, and the related consolidated statements of operations, stockholders'
equity, and cash flows for the period February 24, 1995 to December 31, 1995.
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 audit.
    
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
   
     In our opinion, the financial statements referred to above, present fairly,
in all material respects, the consolidated financial position of Doctors Health
System, Inc., and Affiliates as of December 31, 1995, and the consolidated
results of their operations and their consolidated cash flows for the period
February 24, 1995 to December 31, 1995, in conformity with generally accepted
accounting principles.
    
   
     We have also audited Schedule II -- Valuation and Qualifying Accounts for
the period February 24, 1995 to December 31, 1995. In our opinion, this schedule
presents fairly, in all material respects, the information required to be set
forth therein.

     Baltimore Medical and Carroll Medical are engaged in the practice of
medicine and the state in which DHS operates prohibits it from owning an
organization which engages in the practice of medicine. Both of these entities
are parties to PSO and Practice Participation Agreements with grant DHS
unilateral and perpetual control over their operations, personnel, facilities
and business activities. DHS has agreed to assume the responsibility for all
operating expenses, to provide financial management, information systems,
marketing, advertising, risk management and administrative support for
utilization review and quality care, among other services. Revenue for medical
care services provided is billed and collected by DHS on behalf of the
affiliates. The amounts collected by DHS, less the allocated costs attributable
to the medical practice and provision of related health care services by the
physician, are remitted to the respective affiliates , from which they are
obligated to pay base employee physician salaries. An incentive bonus, if any,
to be paid to employee physicians shall be determined by the Management
Committee of each core medical group. DHS receives fees, for services provided
to the CMG's laboratory facilities, which fees amounted to $222,300 in 1995 and
have been eliminated in consolidation.
    
   
     The PSO agreements, as amended to reflect the intent of the parties,
generally have terms of 30 years, renew automatically for successive 10 year
periods, and may only be terminated for cause by the Affiliate. The Company may
unilaterally terminate the agreement with cause. The agreements (i) require the
Company to continue to invest capital for facilities, equipment and fixtures for
use in the medical practices (ii) employ the majority of non-physician
professional and administrative personnel (iii) recruit new PCPs and other
medical personal and (iv) negotiate, enter into, administer and terminate
contractual arrangements on behalf of the Affiliates.
    
   
     As indicated above, DHS has unilateral control over the assets and
non-medical operations of its affiliates through various contractual
arrangements, notwithstanding the lack of majority of ownership of such
entities. As a result of this control, a parent-subsidiary relationship under
generally accepted accounting principles exists; therefore, DHS has consolidated
the financial statements of the affiliates from the inception of their
operations. It is the Company's belief that consolidation is necessary to
present fairly the financial position and results of operations of the Company.
    
   
     Baltimore Medical and Carroll Medical, which were formed in February, 1995
and November, 1995 are owned by the Employee Member Physicians who are general
and/or limited partners in Maryland Holdings Limited Partnership (MHLP). At
December 31, 1995, MHLP owned approximately 47.8% of the outstanding shares of
DHS on a fully diluted basis. The shares owned by MHLP in DHS were issued in
contemplation of having approximately 66 full-time equivalent physicians being
admitted as limited partners. Accordingly, the group of 66 physicians are
considered to be founders. Two of these founders, Drs. Rifkin and Kimmel,
collectively own 4.4% of DHS directly, are part owners of the 1% general partner

MHLP, limited partners in MHLP and Member Physicians of Baltimore Medical. As of
December 31, 1995, there were 31 founding physicians who were member, general
and/or limited partners in MHLP. Subsequent to December 31, 1995, either through
acquisition or by letters of intent, the Company has reached the scheduled
number of limited partner physicians set forth in the MHLP partnership
agreement. The 1% general partner of MHLP is BMGGP, Inc., which is owned equally
by 17 of the MHLP limited partner physicians. The 99% limited partners of MHLP
are currently Member Physicians employed by of either Baltimore Medical or
Carroll Medical.
    
   
  ACQUISITION OF ASSETS OF AND EMPLOYMENT OF FOUNDING PCPS

     In connection with its formation strategy, each founding PCP who was
employed by DHS (generally by either Baltimore Medical or Carroll Medical)
agreed to transfer certain of their medical practice fixed assets at their
historical depreciated book value in exchange for cash, their patient
receivables for a promissory note and/or cash and certain intangible assets in
exchange for a 1.5% fully diluted limited partnership interest in MHLP.
    
   
     A summary of the significant accounting policies consistently applied in
the preparation of the accompanying consolidated financial statements follows.
    
   
  BASIS OF PRESENTATION

     The consolidated financial statements of Doctors Health System, Inc. ("DHS"
or the "Company") include its wholly-owned and majority-owned subsidiaries,
Doctors Health System Primary Care IPA, Inc., Doctors Health System -- Medalie
Equipment Corporation, and WomanCare IPA, LLC, and its commonly owned or
controlled affiliates, Baltimore Medical and Carroll Medical from the date of
their affiliation. All significant inter-entity and intercompany balances and
transactions are eliminated.
    

  REVENUE RECOGNITION

     Revenues for physician services are generated from direct patient 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.
   
     During 1995, approximately 12.9% of the Company's net revenues came from
gatekeeper capitated contracts on which the Company received a fixed, prepaid
monthly fee for each enrolled life in exchange for providing primary care
medical services. The balance of the Company's revenues were derived from
medical care delivered on a fee for services basis. In the future, the Company
expects to derive a significant portion of its revenues from global capitated
contracts.
    
  MEDICAL SUPPLIES

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

  INCOME TAXES

     DHS is a corporation subject to federal and state income taxes. 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 affiliates 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.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
    
NOTE 1 -- BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- Continued
  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents.

  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.

  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. Routine maintenance and repairs are charged to expense as incurred.
   
  DEFERRED CHARGES AND INTANGIBLE ASSETS

     Deferred charges are comprised of deferred loan acquisition costs, deferred
physician employment contract costs and organization costs. These costs are
being amortized to operations on the straight-line basis over the term of the
loan (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 market value of net assets acquired (goodwill) from a retiring physician.
Intangible assets are being charged to income over 10 years, or the period of
the initial employment agreement with the physician whose practice has been
acquired, whichever is shorter. Management does not believe that any current
factors indicate an impairment of goodwill acquired. Management will review the
carrying value at each future reporting period to determine if any impairment
has occurred.
   
  FAIR VALUE OF FINANCIAL INSTRUMENTS

     Cash and cash equivalents, accounts receivable, notes payable, accounts
payable, and accrued liabilities are reflected in the financial statements at
fair value because of the short maturity of those instruments. The fair values
of the Company's other financial instruments are disclosed in note 12.
    
  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

     Management does not anticipate that the provisions of Statement of
Financial Accounting Standard No. 121, ACCOUNTING FOR THE IMPAIRMENT OF
LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF, which is
effective for years beginning after December 15, 1995, will have a material
impact on the Company's financial statements.
    
   
     In October 1995, Statement of Financial Accounting Standards (SFAS) No.
123, ACCOUNTING FOR STOCK-BASED COMPENSATION, was issued. As permitted by SFAS
No. 123, the Company will continue to follow the accounting provisions of
Accounting Principles Board (APB) Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO
EMPLOYEES, for applicable transactions with

                                      F-11

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

NOTE 1 -- BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- Continued
employees. The Company will adopt the accounting provisions of SFAS No. 123 for
transactions entered into after December 15, 1995 with individuals or
organizations other than employees. The Company plans to adopt the disclosure
requirements of SFAS No. 123 in 1996. Management believes that adoption of SFAS
No. 123 will not have a material effect on the Company's financial statements.
    
NOTE 2 -- RISKS AND UNCERTAINTIES

     It is reasonably possible that future near term events may result in
changes in estimates that would be material to the financial statements.
Significant estimates are as follows:

  LIQUIDITY

     The foregoing business description discusses the current nature of the
Company's operations. The Company has not yet obtained the desired number of
contracts for prepaid (capitated) medical services. Many of these contracts are
currently being negotiated. Management plans to enter into contracts during 1996
on a schedule that integrates the Company's physician recruiting effort with the
obligation to provide health care services. At December 31, 1995, management
believes that the consolidated financial position, equity and results of
operations of the Company are consistent with its business plan. Management
intends to conduct operations in 1996 in accordance with that plan and expects
to have adequate capital to conduct its operations. There is no assurance that
the company will meet its plan, attain the necessary contracts required or
implement its plan profitably.

  ACQUISITION OF MEDICAL PRACTICE ASSETS

   
     The Company has acquired certain tangible assets, patient receivables and
contract rights of 31 practices as of December 31, 1995. These have been
accounted for as asset purchases at the founders' cost. 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. In the acquisition process, the Company uses the services of
outside professionals. The expenses and fees incurred for these professional
services are considered part of the acquisition cost and are capitalized in the
financial statements as deferred acquisition costs. In the event that a
physician exercises his option to leave, the Company charges any unamortized
deferred costs associated with the acquisition to operations in the period when
notice of withdrawal is received. At May 1, 1996, 9 of these physicians
(unaudited) have remaining reacquisition options for periods expiring through
August 1996. There has been one cancellation by a physician. This cancellation
did not require the disbursement of cash or other assets since the transaction
was never funded.
    

  INVESTMENT IN TANGIBLE ASSETS AND INFRASTRUCTURE

     For the year ended December 31, 1995, the majority of the Company's revenue
resulted from the delivery of health care services on a fee for service basis.
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 obtain long-term
contracts for global capitated care with a number of payors. In the event these
contracts are not obtained, the Company would most likely be unable to generate
sufficient revenues to cover its ordinary and necessary expenses. Many of the
contracts are in negotiation at December 31, 1995 and management expects that
they will come to fruition within the next operating cycle. If that level of
operations is not achieved these assets may be impaired since the Company would
not require all of the assets owned or leased.

NOTE 3 -- LOAN AGREEMENT AND GUARANTEE

     In December 1995 DHS entered into a loan agreement with its commercial
bank, under which DHS 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 DHS designates a portion of the advances to be subject to the
Eurodollar rate plus .75%. All advances are due at December 31, 1997. No
advances under the agreement were outstanding at December 31, 1995; however,
during 1995

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
    
NOTE 3 -- LOAN AGREEMENT AND GUARANTEE -- Continued
advances were outstanding under a similar prior agreement. The bank has the
right to offset DHS demand deposit accounts with the bank against any past due
amounts.
   
     The loan agreement is guaranteed by the holder of DHS Series B Preferred
Stock. The guarantee is collateralized by a security interest in all receivables
and the PSO between DHS and Baltimore Medical. The guarantee agreement also
provides for certain restrictions on DHS, including limitations on incurrence of
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 DHS is required to obtain a release of the guarantee. As
consideration for the guarantee, DHS issued a warrant valued at $370,000 for the
purchase of its common stock (see note 11).
    
   
NOTE 4 -- NOTES PAYABLE

     Baltimore Medical has an agreement with its commercial bank that provides
for a line of credit for $150,000 that matures on February 29, 1996. Interest
accrues on advances at the bank's prime rate plus 1 1/2% per annum (10%
effective rate at December 31, 1995) and is payable monthly. The line is
collateralized by accounts receivable and certain equipment. Advances under the
line were $57,000 at December 31, 1995. The Company is required to be out of the
line for 90 days annually. In February 1996, the Company and the bank agreed to
revised 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 plus 1/2%.

     In connection with the acquisitions of individual medical practice assets,
the Company is obligated on short-term notes payable to two member physicians
aggregating approximately $23,400 at December 31, 1995.

     The Company is also obligated on a note payable to an employee physician in
the amount of $37,500. The note bears interest at 10%. Approximately one-half of
the balance was paid in January 1996, and the remainder is due in June 1996.
    
NOTE 5 -- LONG-TERM OBLIGATIONS

     Long-term obligations at December 31, 1995 are comprised as follows:

</TABLE>

     The Company is obligated on notes payable to various physicians, who are
partners in MHLP and members of either Baltimore Medical or Carroll Medical, in
connection with the original contribution of the accounts receivable from the
physicians' former practices to MHLP. The notes bear interest at rates ranging
from 9.75% to 10% and the notes mature in the event of: (i) termination of the
respective Professional Services Employment Agreements, (ii) a liquidating
distribution to the stockholders of DHS, (iii) combination, consolidation or
merger where DHS is not the survivor, (iv) disposal of substantially all of DHS'
assets, or (v) a public offering with a certain issuance amount to DHS. The
notes may be reduced or adjusted based on receivable collections and may be
prepaid without penalty. These notes have been classified as long-term since
repayment is not expected in the next operating cycle.

NOTE 6 -- CAPITAL LEASE OBLIGATIONS

     The Company has entered into a capital lease for computer equipment and
software. Also, in connection with the acquisition of a medical practice, the
Company assumed a capital lease for certain laboratory equipment. These leases
are noncancelable and have terms that expire at various dates through 1999.
Assets under capital leases as of December 31, 1995 approximated:

NOTE 7 -- 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. The Company has obtained retroactive coverage for
physicians that were not previously covered by the current carrier (prior to the
physician's affiliation with DHS). The 1995 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, for example, selection of the
underwriter, form of the insurance policy and 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 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 any 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.

  HEALTH CARE DELIVERY COSTS

     The Company has contracts with physician groups to provide health care
services to participants enrolled in certain health maintenance plans. The
expenses associated with these contracts are recorded as incurred over the
contract term. The Company's responsibility for the cost of continued care is
limited to amounts paid to its primary care physicians. Apart from primary care,
the Company's responsibility is to refer enrolled members to the appropriate
specialist and/or care facility, as provided in the contract.

NOTE 7 -- COMMITMENTS AND CONTINGENCIES -- Continued
     The Company is negotiating future global capitated contracts with various
payors of health care services that contain provisions, including performance
criteria, that may increase the Company's risk.

     The Company competes for physicians with other managed health care
providers in the geographic area in which it does business. The Company's
ability to obtain managed care contracts is dependent upon the development of a
sufficient number of physicians.

  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 1997.

     Effective February 1, 1996, the Company adopted a Flexible Benefits Plan
covering all full-time employees. Subject to certain limitations, the Company
may make "nonelective 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 $418,000 ($30,300 for
leased property owned by member physicians) in 1995. In 1996, the Company
entered into an operating lease for additional office space for its corporate
headquarters. Minimum rental commitments, excluding sublease income, under
operating leases as of December 31, 1995, with existing or renewable terms
greater than one year are as follows:

  PREFERRED STOCK CONVERSION AND REDEMPTION RIGHTS
   
     Both Series A Convertible Preferred Stock and Series B 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 DHS stock. Only the fully-paid shares are subject to conversion. The
effects on the Company's capital accounts, assuming conversion is reflected in
the March 31, 1996 unaudited pro forma balance sheet.
    
   
     Between March 1 and June 1, 2000, the Series A and Series B Convertible
Preferred Stockholders have the right to require DHS to redeem all of their
shares at the greater of fair market 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, DHS has the right to
redeem the outstanding shares at the issuance price plus unpaid dividends and
interest thereon for Series A Preferred Stock. It may also redeem the Series B
Preferred Stock on the same terms that the holders could require DHS to pay on a
requested redemption by the holders.
    
     In addition, upon the occurrence of certain events, Series A and Series B
Convertible Preferred Stockholders have the right to require DHS, and DHS 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 DHS decides to take certain actions without the approval of the
Series A and Series B Convertible Preferred Stockholders then the Preferred
Stockholders have the right to require DHS to redeem all of their outstanding
shares. In the foregoing instances the redemption price is the greater of fair
market value or the issuance price plus unpaid dividends and interest thereon.
If DHS elects to enforce certain non-competition covenants with the Series B
Preferred Stockholder, then the holder may require DHS to redeem the shares held
for the greater of $4.8 million or par value plus unpaid dividends and interest
thereon. If DHS 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 DHS to redeem their shares at the greater of: (1) the
purchase price of the adverse junior stock on a fully diluted basis, (2) fair
market value, or (3) 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, DHS
received a note in the original amount of $3 million ($2.5 million balance at
December 31, 1995). The note bears interest at 6.5% per annum, compounded
quarterly, and interest is payable only to the extent that DHS 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 DHS until
February 14, 1998, but interest continues to accrue on any unpaid balance. As of
December 31, 1995, DHS had elected to defer $750,000 of scheduled 1995 payments.
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. DHS has the option to require payment of
any outstanding principal and interest on February 14, 1998, or DHS may elect to
redeem the outstanding Series A Preferred Stock and cancel the remaining
principal and interest.

  PREFERRED STOCK DIVIDENDS

     Series A 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 Convertible Preferred Stock
under the related note receivable.

     Series B 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
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 Preferred Stock accrued and undeclared
dividends at December 31, 1995 are as follows:

</TABLE>

     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 DHS, 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 market 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
distribution amount due to each preferred stockholder is limited to the amount
of cash paid to DHS 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 9 -- STOCKHOLDERS' EQUITY -- Continued
   
of the stockholders' agreement, the Company may be required to purchase shares
of the Company's capital stock in certain circumstances, such as: (a) 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 DHS is required to purchase all of the
offered shares at fair market value (as agreed to by the parties or as
determined by an independent appraisal); (b) Class A Common Stock purchased by
Dr. Rifkin or Dr. Kimmel after December 1, 1995, if their employment is
terminated, in which case DHS is required to purchase these shares at fair
market value (as agreed to by the parties or as determined by an independent
appraisal); (c) 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 DHS is required to
purchase all of the shares offered. If termination is without cause, the
purchase price is based on fair market 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 December 31, 1995, 600,000 shares of Class A Common Stock were
subject to such repurchase requirement. If DHS 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,(d) All classes of capital stock -- upon the occurrence of an involuntary
transfer involving any of its outstanding capital stock, DHS has the right of
first refusal to purchase the offered shares at fair market 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. During 1994, the Company issued Class
A Common Stock to the originating stockholders.

  OTHER OWNERS' EQUITY

     The consolidated financial statements include the consolidated accounts of
DHS consolidated with commonly owned or controlled Affiliates.
   
     Baltimore Medical and Carroll Medical are limited liability companies
(LLCs) organized under the laws of the State of Maryland in February 1995 and
November 1995, respectively. Each LLC will continue in existence until December
31, 2025, unless terminated sooner in accordance with their respective operating
agreements. All of the Member Physicians of the LLCs are active physicians who
are limited partners in MHLP. At December 31, 1995, the LLCs were the primary
contracting entities the Company contracts with for the delivery of health care
services. The contracts of the LLCs provide for exclusivity with DHS, and the
LLCs are precluded from contracting with any other party. At December 31, 1995,
the contributions to members' capital were as follows:

non-exclusive network of primary care and specialist physicians to provide
health care services. DHS Primary Care had not commenced operations at December
31, 1995.

     Doctors Health System-Medalie Equipment Corporation (Medalie), a
wholly-owned subsidiary of DHS, was organized in December 1995 to acquire and
hold equipment to be used in the practice of medicine. Medalie had not commenced
operations at December 31, 1995.

     DHS has an 87.5% interest in WomanCare IPA, LLC (WomanCare), which was
organized May 1995. The remaining interest in WomanCare is owned by a physician.

NOTE 10 -- STOCK OPTIONS

     DHS has an Omnibus Stock Plan (the Plan) accounted for under APB Opinion 25
and related Interpretations with respect to employee transactions and SFAS No.
123 with respect to transactions with others. The Plan permits DHS to grant

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
    
NOTE 10 -- STOCK OPTIONS -- Continued
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 DHS. SARs entitle the optionee to surrender
unexercised stock options for cash or stock equal to the excess of the fair
market 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 DHS 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 market value of the shares on the date the option is
granted. INCENTIVE stock options are granted only to employees of DHS.
   
     On August 10, 1995 and October 18, 1995 DHS granted INCENTIVE stock options
to ten employees for a total of 123,380 shares at the exercise price of $0.01
per share, the estimated fair value of the shares at the date of grant. The
options become exercisable on various dates ranging from April 1, 1996 through
April 1, 2000. Upon exercise, 57,302 shares issued are 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
DHS or the employee's death, disability, retirement, or termination without
cause.
    
   
     On December 21, 1995, DHS granted NON-QUALIFIED stock options 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 are 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 DHS or the employee's death, disability, retirement, or
termination without cause. The Company will recognize compensation expense as
the options are exercised and the shares vest in future periods, based upon the
option price and fair market value at the date of grant.
    
NOTE 11 -- COMMON STOCK PURCHASE WARRANTS

     In consideration for the guarantee of a loan agreement, DHS issued a
warrant to its Series B Preferred Stockholder for the purchase of 88,889 shares
of DHS 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 (i.e., 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 December 31, 1995, 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.
   
     In consideration for certain consulting services, the Company has issued
warrants for the purchase of 24,000 shares of DHS common stock at $11.25 per
share (a price greater than management's estimate of fair value at the date of
grant). These warrants expire December 1, 2005, and are exercisable if there is
a change in control of DHS.
    
   
NOTE 12 -- FAIR VALUE OF FINANCIAL 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:

  REDEEMABLE CONVERTIBLE PREFERRED STOCK AND SERIES A PREFERRED STOCK
SUBSCRIPTION RECEIVABLE

     The Company believes that it is not practical to estimate a fair market
value different from the carrying values of these financial instruments. The
Series A and Series B Preferred Stock are carried at issue price plus accrued
dividends, and have

NOTE 12 -- FAIR VALUE OF FINANCIAL INSTRUMENTS -- Continued
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 14 -- INCOME TAXES
    
     The Company has incurred a net loss from operations of $3,180,723.
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. This loss may be
carried forward for 15 years expiring in 2010. Under federal tax law, certain
potential 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 December 31, 1995. Deferred tax
assets (liabilities) at December 31, 1995, consist of the following:

NOTE 17 -- SUBSEQUENT EVENTS
   
  INTEGRATED HEALTH CARE DELIVERY SYSTEM

     The Company and MCNET, Inc. (MCNET), located in Chevy Chase, Maryland, have
entered into a letter of intent for the formation of a physician led integrated
health care delivery system (IDS). The resulting affiliate intends to provide
health care services to residents of Maryland and people who work in Maryland
and surrounding areas. There are approximately 446 physicians associated with
MCNET, of which 153 are primary care physicians. This transaction also
contemplates participation by the individual physicians who are currently
members of MCNET. Negotiations with the individual physicians may not proceed
until DHS has filed a registration statement with the Securities and Exchange
Commission. Negotiations with MCNET have not proceeded as planned and therefore,
management does not believe the transaction contemplated by the letter of intent
will occur, however discussions are ongoing.
    
   
  GLOBAL CAPITATED CONTRACTS

     The Company has entered into a contract and a letter of intent in lieu of a
contract to provide health care services under capitated plans with HMOs that
are consistent with those described in note 1. Delivery of care and monthly
receipt of capitated income will begin in early 1996. These arrangements are
global capitated contracts whereby the Company is responsible for the management
of specialty and facilities care, in addition to the primary care component.
Capitated premiums are due monthly and will be recognized as revenue during the
period the Company is required to provide services under the respective
contract. A provision for additional risk-sharing revenue (or loss) will be
reported in the period in which services are rendered. Differences between
original estimates and subsequent revisions will be reported in the period the
revisions are made. The cost of providing services under the contracts will be
recorded as services are rendered, including an estimate for services rendered
but not yet reported. An estimated loss will be recognized when it is probable
that expected future health care costs will exceed anticipated capitated
receipts and stop-loss insurance recoveries.

NOTE 19 -- PRO FORMA ADJUSTMENTS (UNAUDITED)

     The pro forma balance sheet as of March 31, 1996, reflects the conversion
of preferred stock into common as though conversion had occurred as of March 31,
1996. The pro forma adjustments are as follows:

     (1) At the time of conversion, the Company is required to pay all accrued
         preferred stock dividends plus any interest thereon, less accrued
         interest due DHS on the note receivable balance due of $2,500,000. The
         net balance due as of March 31, 1996 is reflected as an increase in the
         Company's line-of-credit in the pro forma balance sheet.

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

                                      II-1

<PAGE>
in one or more of such capacities, against any and all liabilities incurred in
connection with their services in such capacities, 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 15. RECENT SALES OF UNREGISTERED SECURITIES
   
     In December 1994, the Company issued 150,000 shares of its Class A Common

Rifkin and Alan Kimmel 25,000 shares each of Class A Common Stock (which
pursuant to a stock split are currently 100,000 shares of Class A Common Stock).
The shares were issued for nominal cash consideration and in consideration for
services performed for the Company as founders of the Company.
    
   
     In February of 1995, the Company issued 1,100,000 shares of its Class B

May 1996), the Company issued options to purchase a total of 200,880 shares of
Class A Common Stock and authorized the issuance of options to purchase an
additional 5,000 shares of Class A Common Stock to certain employees who joined

per share, none of which have been exercised as of the date of this Registration
Statement.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes:
 
     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement;
 
          (i) To include any Prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;
 
          (ii) To reflect in the Prospectus any facts or events arising after
     the effective date of the Registration Statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     Registration Statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high 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
offering.
 
     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
 
                                      II-4
 
<PAGE>
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.

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

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

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
any lease or mortgage, by whatever name, on the Office Space or the Units.

         i.       Taxes.  Doctors Health shall pay before  delinquency all real
estate and  property  taxes  imposed upon the Office Space or the Units for
which it is responsible. The LLC shall pay before delinquency (and hereby

other charges imposed upon the LLC's  operations  or business  conducted  upon
the  Demised  Premises, and/or upon any property of the LLC located in the
Demised Premises.

extended  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 Doctors Health and shall name Doctors Health as loss payee
and as an 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

<PAGE>

any item thereof  by any other  Person  other  than in the  ordinary  course of
the LLC's business.

         m.       Damage/Destruction/Casualty of Demised Premises. In the event
all or 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 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. Doctors Health 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.

3.       OPERATIONAL DUTIES OF DOCTORS HEALTH.

on behalf of the LLC ("Business  Costs"),  including without  limitation,  the
following charges (or, where applicable and consistent with Section 4.c hereof,
a reasonable allocative share of such charges):  (a) all personnel costs
attributable to the LLC and its Practice of Medicine,  including  (1) all

salaries, wages, bonuses and all benefits of professional  and  administrative
staff  employed by Doctors  Health to provide services  directly to the LLC or

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
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.

<PAGE>

                           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 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
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)  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
or other amounts  credited to the LLC Accounts by the  depository  bank,  during
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
being made.  Doctors Health'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  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
Health to review the  financial  records  of LLC (which may be Doctors

                                       14

<PAGE>

Health's accountants).  Doctors  Health  shall  permit  the LLC's  accountants
to review Doctors  Health's  calculation of its  Compensation  at least
quarterly and 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

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 join as parties to such procedures any other medical
service  provider  involved directly or indirectly in a dispute  between
Doctors Health and the LLC or join the LLC as a party in any dispute  between
Doctors Health and any other service provider that relates to the LLC.

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.

                                       25

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

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.

non-competition (and other) provisions of each Professional Services  Employment
Agreement,  will not, without the prior written consent of Doctors Health, enter
into employment agreements or other contracts with primary care physicians that
do not contain substantially  similar provisions,  and will take any and all

         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 LLC or in connection  with any  partnership,  corporation,  joint venture or
other Person, without the prior written consent of Doctors Health.

to, the execution of any necessary  documents,  and the filing of any forms,

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

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

         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.

                                FORM OF SUBLEASE


         THIS SUBLEASE ("this Sublease"),  ____day  of___________,  199_, by and
between  Doctors  Health  System,  Inc.,  a  Maryland  Corporation,   ("Tenant")
BALTIMORE   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

                                       37

                              EMPLOYMENT AGREEMENT


         THIS EMPLOYMENT AGREEMENT is executed this ___ day of ___________, 19__
("Effective  Date"), by and between  _____________________MEDICAL  GROUP, LLC, a
Maryland    limited    liability    company   (the   "Medical    Group"),    and
[M_2_Name_of_New_Doctor] (the "Physician").

         The parties to this Agreement,  intending to be legally bound, agree as
follows:

          1.      Purpose.  The  Medical  Group  desires  to employ  the
Physician  to engage in the  practice  of medicine  through  the Medical  Group
(the  "Medical  Practice")  and the  Physician  desires to be employed by the
Medical Group on the terms and conditions set forth in this Agreement.

          2.      Scope of Employment; Physician Covenants.

                  2.1 Employment. The Physician agrees to devote his or her best
efforts and full  professional  time to the practice of medicine  exclusively on
behalf of the  Medical  Group.  The  Physician  agrees  that,  except  for those
activities  described  on  Schedule  2.1, he or she will not engage in any other
employment or professional  activity  during the Term of this Agreement  without
the prior written consent of the management  committee of the Medical Group (the
"Management Committee").

                  2.2 Law and policies.  The Physician agrees to comply with all
of (i) the terms and  provisions  of  applicable  law and  professional  ethical
standards  relating to the practice of medicine in  Maryland,  (ii) the policies
and procedures established by the Management Committee,  and (iii) the rules and
regulations at any hospital at which the Physician  agrees to practice  medicine
on behalf of the Medical Group. The Physician agrees to notify the Medical Group
as soon as possible of any personal illness and/or other inability to work.

                  2.3  Relocation.   The  Medical  Group  anticipates  that  the
Physician  will  conduct  his or her  Medical  Practice  from his or her current
location during the Term. However,  after consultation with the Physician it may
be  advisable  to relocate the Medical  Practice to provide  appropriate  office
space

and optimal geographic coverage within the Medical Group's patient service area.
If the  Physician  is  moved  without  his or her  consent,  he  will  be
reimbursed for any lost income and "made whole" by the Medical Group.

                  2.4  Administrative  and  other  duties.  Physician  agrees to
accept  assignments  to perform such duties related to the Practice of Medicine,
including  administrative  and medical  director  duties,  as may  reasonably be
assigned  by the  Medical  Group from time to time after  consultation  with the
Physician in accordance with applicable Medical Group policies. In the event the
Physician is required to perform administrative duties beyond those performed by
other  physicians with  employment  agreements with the Medical Group similar to
this employment agreement, he or she shall be compensated on terms determined by
mutual agreement of the parties.

                  2.5 Reimbursement Agreements.  The Physician agrees to execute
any agreements necessary for the Medical Group and Physician's  participation in
and reimbursement from medical programs  administered by public or private third
party payors and other  private  managed care  programs  approved by the Medical
Group or with whom the Medical Group otherwise contracts (directly or indirectly
through one or more agents) as a participant or a provider.  Physician agrees to
maintain such practice patterns, including abiding by specialty consultation and
other referral restrictions, as may be required by the Medical Group, whether as
a result of such public or private managed care programs, or otherwise.

          3.      Term. The "Initial Term" of this Agreement  shall begin on the
date first  above  written and shall end on  _______________.  This  Agreement
shall automatically  be renewed  thereafter for additional  terms (each an
"Additional Term") of three (3) years each unless  written  notice of the
intention  not to renew  at the end of the  Initial  Term or any  Additional
Term is given by the Physician to the LLC at least one hundred  twenty (120)
days prior to the end of such term. (The Initial Term and all Additional  Terms
are herein referred to as the "Term.")

          4.      Termination.

                  4.1  Termination  upon  Death.  If the  Physician  dies
during  the  Term,  the  Physician's employment shall terminate as of the date
of death of the Physician.

                  4.2  Termination  upon  Disability.  Notwithstanding  any
other provision  of  this  Agreement,   if  during  the  Term  the  Physician
becomes physically,  mentally or emotionally  disabled,  as determined by an
independent qualified  physician,  so that the Physician is, in the good faith
determination of

                                       2

the Management Committee, substantially unable to perform his or her services
hereunder  for (i) a period of 6  consecutive  months,  or (ii) shorter  periods
aggregating  180 days  during  any twelve  month  period,  then the  Physician's
employment  hereunder  shall  terminate  as of the  date of such  determination.
However,  in the event the  Physician  has within  his or her employ  during the
period of total  disability,  a physician duly licensed to practice  medicine in
the state of Maryland,  who is approved in advance by the Medical Group, and who
continues to generate sufficient revenues to permit the Medical Group to pay all
direct and indirect costs  associated with Physician's  Medical Practice during
any period of disability, then the Physician's employment shall not terminate as
provided above.

                  4.3      Termination by the Medical Group.

                           (a)      The Medical Group may  terminate  this
Agreement for "Good Cause"  immediately upon written notice to the Physician if
the Management Committee, after delivery of  reasonable  prior notice to the
Physician  and a fair hearing on the merits attended by the Physician and his or
her attorney, determines that:

                                            the State of Maryland or has had his
                                            or her license to practice  medicine

                                            limited  or  suspended  by action of
                                            any regulatory body;

                                    (ii)    the   Physician   ceases   to   have

                                            hospitals  and  other   institutions
                                            scheduled on Schedule 4.3(a)(ii), or
                                            his or her  privileges  at any  such
                                            hospital  or other  institution  are
                                            suspended or limited in any material
                                            way,   for   reasons    other   than
                                            temporary   suspensions  for  record
                                            keeping      or     a      voluntary

                                            which  has  been   approved  by  the
                                            Management Committee;

                                    (iii)   the  Physician  fails to perform his
                                            or her duties in a manner consistent
                                            with the  professional  and  ethical
                                            standards of the medical  profession
                                            and as established by the Management

                                            Physician   engages  in  illegal  or

                                            substantially   detrimental  to  the

                                            they     come    due    and    these
                                            circumstances  negatively affect the
                                            Physician's   ability  to   practice
                                            medicine   in   an   efficient   and
                                            professional manner;

                                            rates;

                                            provided,  however,  that the
                                            Management Committee in the exercise
                                            of its discretion  hereunder  shall

                                            circumstances  that  prevent the
                                            Physician from   rendering   such
                                            services   (other  than  those
                                            circumstances otherwise set forth in
                                            this Section 4.3(a)); or

                                            forth  in  this   Agreement,   which
                                            failure   is   not   cured   to  the
                                            reasonable   satisfaction   of   the
                                            Management  Committee  within thirty
                                            (30) days  after  receipt  of notice
                                            from the Management Committee.

                           (b)      In  addition  to  the  Medical  Group's
right  to  terminate  the  Physician's employment  pursuant to Section 4.3(a),
and  notwithstanding any other provision of this Agreement,  the Medical Group
may, for any or for no reason, and without "Good Cause",  terminate the
Physician's  employment upon 60 days prior written notice to the  Physician
only upon the  payment  of all  amounts  described  in Section 4.5(b).

                  4.4      Termination by the Physician.

                           (a)      Notwithstanding  any other provision of this
Agreement,  the Physician shall be entitled to terminate his or her  employment,
effective on the sixtieth  (60th) day  following  written  notice  of
termination  delivered  to  the  Management Committee,  if the Medical Group
commits a material  breach of this Agreement or otherwise  engages in acts or
omissions  that would  constitute a  "Constructive Termination"  (defined
below) of the  Physician's  employment  with the Medical Group and such material
breach or Constructive  Termination  remains uncured by the Medical Group after
reasonable prior written notice of termination from the Physician; provided,
however, that if such Constructive Termination is caused by the Physician's
incapacity or inability to serve due to a disability of the type described in
Section 4.2 above and the Medical  Group  elects to  terminate  the Physician
pursuant to the provisions of Section 4.2, the Physician  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  only  those  circumstances
where  (i) the  Medical  Group  creates  working conditions  that a  reasonable
physician  in  the  Physician's  position  would consider unreasonable and
intolerable or (ii) the Medical Group fails to pay the Physician  his  or  her
Base  Salary  when  there  are  adequate  funds  in the Physician's Care Center
account to pay such Base Salary.

                  4.5      Compensation and Benefits Following Termination of
Employment.

                           (a)      In the event of termination of the
Physician's  employment for any reason other than a termination  pursuant to
Section 4.3(b) (without cause) or Section 4.4(a) (constructive termination):

                                    (i)     all  compensation  and other
                                            benefits  payable or  provided

   Health,  the  Physician  agrees  to and does  hereby  indemnify  and hold the
   Medical Group and its Affiliates harmless from any liability,  claim, demand,
   judgment or costs relating to or arising out of any acts or occurrences of or
   relating to the  Physician  which either arose prior to the execution of this

                                       12

<PAGE>

   Agreement or which are outside the scope of the  Physician's  employment  and
   duties hereunder.

                  8.4  If  the  Physician  carried  a  policy  of  "claims
   made" insurance  prior to his or her employment  with the Medical  Group,
   then the Physician  shall  cooperate  with the  Medical  Group in
   purchasing,  at the expense of the  Physician,  coverage  that will  prevent
   a lapse of insurance coverage of the Physician  ("tail  coverage") and shall
   keep such coverage in effect as long as the Management Committee determines
   is necessary to protect the Medical Group against claims arising against the
   Physician.

         9.       Other Benefits.

                  9.1  The  Medical  Group  shall  provide  the  Physician  with
additional benefits as the Management Committee may in its discretion establish,
based upon the same eligibility  criteria and on the same basis as such benefits
are available to similarly  situated  physician  employees of the Medical Group,
and using the Effective Date as the  Physician's  anniversary  date to determine
eligibility.

         10.      Patient Records.

                  10.1  All patient records, files, charts, x-ray films and
other written or recorded material  pertaining to patients of the Medical Group
shall, as between  the  Physician  and the  Medical  Group,  be and remain the
sole and exclusive  property of the Medical  Group during the Term of this
Agreement and thereafter,  provided, however, that nothing contained herein
shall be construed as  preventing  or impairing the right of any patient to
select the physician of his or her choice to render  services to that  patient,
and the  Medical  Group shall  comply  with  all  reasonable  requests  of  any
patient  following  the termination of the Physician's employment regarding the
disposition of copies of said patient's  records,  including but not limited to,
x-ray films,  subject to the Medical Group right to preserve the original
records for its files.

                  10.2  If  following  the   termination   of  the   Physician's
employment,  any patient  should  request  the  transfer of copies of his or her
records  (including  x-ray films) (the "Records") to the Physician,  the Medical
Group  shall  immediately  transfer  duplicate  copies  of  the  Records  to the
Physician and the Physician  shall  reimburse the Medical Group promptly for all
reasonable  out-of-pocket costs incurred by the Medical Group in connection with
the  duplication of the Records and/or  transmission of copies of the Records to
the Physician.  The Medical Group shall pay duplication costs referred to herein
when the  Physician's  employment has been  terminated  under the  circumstances

                                       13

<PAGE>

described in Section  4.3(b) or 4.4 of this  Agreement.  The Medical Group shall
have the full right to set-off all costs and expenses  reimbursable  to it under
the terms of this Section 10.2 from any amounts  payable to the Physician by the
Medical Group after the termination of the Physician's employment,  whether such
amount is payable under this Agreement or otherwise.

         11.      Non-Competition.

                  11.1  General.  The parties  acknowledge that the Medical
Group is engaged in the  business  of  providing  health  care  services as part
of an integrated health care delivery system, including providing these services
under Managed Care contracts with HMOs and other payors (the "Managed Care
Business"). In connection with Physician's employment, the Physician will gain
access to new patients,  payors, providers and confidential information
concerning the Managed Care  Business.  The  provisions of this Section 11 are
necessary to protect the business and goodwill of the Medical Group and its
affiliates.

                  11.2.  Non-competition. During the Term and for a period of
one year  following  termination  of this  Agreement by the Medical  Group for
"Good Cause"  pursuant to Section  4.3(a) and  termination  of this  Agreement
by the Physician pursuant to Section 4.4(a) (collectively,  the "Termination
Events"), the Physician shall not:

                           (i)      engage in the  practice  of  medicine,
within five miles of his or her current location  when a  Termination  Event
occurs,  as an employee or otherwise by or through  a person  or  entity  which
derives  more  than  $1,000,000  in actual collections  from managed care
contracts or similar  arrangements  in any twelve month period;

                           (ii)     become  within five miles of his or her
current  location  when a  Termination Event occurs, an employee of any HMO,
managed health care provider, managed care delivery  system or any other Person,
firm or  corporation or entity engaged in the Managed Care Business;

                           (iii)    except for persons who were patients of the
Physician  immediately prior to the date of this Agreement, and except by way of
general advertisement in the public media,  solicit  patients of the Medical
Group or patients of its  Affiliates in writing or  otherwise  persuade  or
attempt to  persuade  any such  person,  to associate  with  the  Physician
with  respect  to any of  the  foregoing  or to otherwise  discontinue  an
existing  relationship  with the Medical  Group,  its affiliates  or any Payor
which has entered  into a managed  care  contract  with Doctors Health; and

                                       14

<PAGE>

                           (iv)     send any notice or participate  in any
direct mailing or otherwise  communicate with any  patient of the Medical  Group
or any  affiliate  of the Medical  Group (whether or not such patient was an
active  patient of the Physician at the time of termination of employment),
even if such communication is limited to stating that the Physician is no longer
a  participating  provider in any Doctors Health managed care contracts or
similar arrangements.

                  11.3     Enforcement.

                           11.3.1.  If the  Physician  breaches  or  threatens
to  commit a  breach  of any of the provisions  of this  Section  11, the
Medical  Group and each of its  Affiliates shall have the right and remedy (in
addition to any other  rights and  remedies that may be  available) to have the
provisions of this Section 11  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 Doctors Health,  the
Medical Group or their Affiliates and that money damages may not provide an
adequate remedy to the Medical Group and its Affiliates.

                           11.3.2.  If any court  determines  that any  portion
of this  Section  11 is invalid or unenforceable,  (i) the  remainder  of this
Section  11 shall  not  thereby  be affected and shall be given full effect
without  regard to the invalid  portions and (ii) 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.

                           11.3.3.  In the event the Physician  breaches the
provisions of Section 11, the Medical Group  agrees  that  the  damages
recoverable  by the  Medical  Group  from the Physician  shall be  limited  to
(a) money  damages  equal to the cash  Purchase Price;  (b) delivery of the
stock  certificate  representing  the stock Purchase Price from the physician to
Doctors Health; and (c) reasonable attorneys' fees.

                  11.4  The  provisions of this Section 11 shall not apply to
the Physician in the event the physician exercises the walk away rights
described in Section 7 of the Practice  Transfer  Agreement among the Physician,
the Medical Group and Doctors Health dated __________.

                             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 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 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 attorney who is a member of the National Health Lawyers  Association
and who is knowledgeable in the subject matter of the Dispute.

         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.

                                       18

<PAGE>

         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.

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.

                                       19

<PAGE>


8.       Court Proceedings.

         8.1.  Any party may seek temporary or preliminary  injunctive  relief
or actions in summary proceedings from any court of competent jurisdiction prior
to the time the Neutral  Arbitrator  is  appointed.  Any  temporary or
preliminary injunctive  relief granted by a court shall continue  during the
pendency of the Proceeding unless the Panel shall, after hearing, direct
otherwise.

9.       Costs.

         9.1.  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.

         9.2.  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.

10.      Miscellaneous.

         10.1.  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.

         10.2.  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 then applicable  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.

         10.3.  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.  The parties agree that, in determining  any remedy or relief
that the Panel deems  appropriate,  including,  without  limitation,  any remedy
contemplated  under  Section  2.4 of the  Employment  Agreement  whereunder  the
Physician is to be "made whole" as a result of his or her relocation,  the Panel
shall  not be bound  by  judicial  decisions  as to any  limitations  due to the
speculative nature of damages.

         10.4.  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.

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

______________,  (the "Closing Date") by and among  ____________  Medical Group,
LLC, a Maryland limited liability company (the "Medical Group");  Doctors Health
System,    Inc.,    a   Maryland    corporation    ("Doctors    Health");    and
__________________________ (the "Physician").

                  The parties to this Agreement,  intending to be legally bound,
agree as follows:

         1. Purpose.  The Physician has decided to transfer  certain  assets and
liabilities of his medical  practice (the "Medical  Practice") to Doctors Health
and the Medical  Group and to engage in the  practice  of  medicine  exclusively
through  and with the Medical  Group and as an  employee  of the Medical  Group.
Doctors  Health  and the  Medical  Group  desire to acquire  certain  assets and
liabilities of the Medical  Practice,  and the Medical Group wishes to admit the

Practice,  including all assets relating thereto  (excluding  assets used by the

her  Medical  Practice  and the  accounts  receivable  of the  Medical  Practice
outstanding  on the Closing  Date) as listed on Schedule  2.1(a).  The Physician
transfers  to the Medical  Group all of his or her right,  title and interest in
and to any assets as used by the  Physician to provide  laboratory  services and
other services ancillary to his or her Medical Practice as set forth on Schedule

apply  with  appropriate  modifications  to  reflect  the  substitution  of such

                             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 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,

                  3.       dissolution,  termination of existence,  insolvency
or business failure of either party, commission of an act of bankruptcy by, or
appointment of a receiver or other legal  representative  for any part of the
property of either party; or

                  4.       assignment for the benefit of creditors or

party;  entry of an order for relief against either party,  or  commencement  of
any  proceedings under any bankruptcy or insolvency law against either party.

         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

review, storage, and retrieval of records relating thereto.  HMO (through HMO's
Medical Director) and IPA shall jointly  develop a format for an ongoing peer
review and quality  assurance plan that is  consistent  with  the  Federal  HMO
Law  requirements.  The  procedures instituted  by  IPA  shall  be  approved  by
the  HMO's  Medical  Director.  The effectiveness of the peer review and quality
assurance plans shall be monitored by the HMO's Medical Director,  who may
request modifications to such plans when reasonably  required.  The peer  review
and  quality  assurance  plans  shall be designed in such a way that they:

administrative   and  support  personnel  for  IPA  Physicians,   monitoring  of
coordination  of  benefits,  and  patient  satisfaction.  IPA will,  at its sole

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

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.

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:

                                  ATTACHMENT C

                        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.

I.       Professional Services (Including Any Non-Surgical Outpatient Facility
         Costs Associated With These Services)

         A.       Surgical  services  in the  hospital,  in the  office  or in a
                  licensed  outpatient  surgical  facility,  including  surgical
                  assistance  where  medically  required  and   anesthesiologist
                  services performed in connection with surgical services.

         B.       Physician  services for visits and examinations,  including
                  consultation time and time for personal attendance with the
                  patient, during a confinement in a hospital or skilled nursing
                  facility.

         C.       Physician services received in a Physician's office.

         D.       Physician  services in the Member's  home,  including time for
                  personal attendance with the patient when determined necessary
                  by the IPA Physician,  if the Member is too ill or disabled to
                  be  seen  during  regular  working  hours  at the  Physician's
                  office.

         E.       Diagnostic   radiological  (including  MRIs  and  CAT  Scans),
                  laboratory and other  services,  such as  electrocardiography,
                  electroencephalography  and  the  use of  radioactive  isotope

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.

         matrix detailing examples of these items.

         Maryland Medicine:

                  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.

incorporated  (and changes made) in the Medicare Risk Service  Agreement (a copy

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.

                  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.

In order to bind BMA to these terms,  please have this document  endorsed in the
space provided and return the original to my attention.

If you have any questions please give me a call.

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.

delivered by the Physician at the Admission Closing or reasonably satisfactory
to the Physician;
