                                January 30, 1997
    
Dear Fellow Members and Directors:
   
    You are cordially invited to attend the Special Meeting of the Members of
Medtrust Medical Group, Inc. ("Medtrust"), to be held at the Holiday Inn,
located at 1960 Chain Bridge Road, McLean, Virginia 22102, on February 27, 1997
at 7:00 p.m.
    
    At this important meeting, you will be asked to consider and vote on the
Plan and Agreement of Merger, dated as of November 15, 1996 (the "Merger
Agreement") between Medtrust, Doctors Health System, Inc., a Maryland
corporation ("Doctors Health") and Doctors Health of Virginia, Inc., a newly
formed Virginia stock corporation and a wholly owned subsidiary of Doctors
Health ("Doctors Health Virginia"). Doctors Health is a managed care and medical
management company which develops and consolidates individual and groups of
internists, pediatricians and family practitioners, specialist physicians,
hospitals and other health care providers into primary care-driven,
comprehensive managed care health delivery networks. Doctors Health has filed
with the Securities and Exchange Commission (the "Commission") a Registration
Statement which has been declared effective by the Commission in anticipation of
selling its shares in connection with its ongoing strategy of acquiring
physician practices and similar affiliations.
   
    Under the terms of the Merger Agreement and subject to its specific
conditions and provisions, Medtrust shall be merged with and into Doctors Health
Virginia and that Doctors Health Virginia will be the surviving corporation. In
connection with such merger, the members and directors of Medtrust shall receive
in the aggregate 30,000 shares (of which 24,000 shares are referred to herein as
the "Share Consideration") of the Class B common stock, $.01 par value per share
of Doctors Health (the "Class B Common Stock"), plus an aggregate amount of cash
equal to $120,000 plus the amount of cash or cash equivalents held by Medtrust
as of November 15, 1996 which was $47,477.56 less any applicable transaction
expenses of Medtrust not reimbursed by Doctors Health in an amount not to exceed
$25,000 (the "Cash Consideration").
    
   
    Each of the outstanding membership interests of Medtrust will be converted
into and represent the right to receive that number of shares of Class B Common
Stock and that amount of cash determined by multiplying each of the Share
Consideration and the Cash Consideration by a fraction, the numerator of which
is the aggregate Initial Membership Fee paid by the respective Member for its
Approved Physicians (as defined in the Bylaws of Medtrust) and the denominator
of which is the aggregate Initial Membership Fees paid by all Members holding
membership interests in Medtrust (immediately prior to the Effective Date of the
Merger) on behalf of their Approved Physicians. Any resulting fractional shares
will be rounded to the next highest whole share. No cash will be paid in lieu of
fractional shares. The Initial Membership Fee shall include only the initial
membership fees paid by a Member and shall expressly exclude any ongoing dues or
assessments paid by a Member in support of the operational expenses of Medtrust.
    
    The Class B Common Stock received by the Members of Medtrust will be subject
to an Amended and Restated Stockholders Agreement dated September 4, 1996 which
will restrict all transfers of the Class B Common Stock other than a
distribution of such shares to shareholders or partners of the Member. The
restrictions on transfer are more fully described in the Prospectus Supplement
and the Prospectus.
    As a condition to Medtrust's obligations under the Merger Agreement, the
Registration Statement of Doctors Health on Form S-1, under the Securities Act
with respect to the Class B Common Stock (the "Registration Statement") must
have been declared effective by the Securities and Exchange Commission such that
the shares received by the members of Medtrust in connection with the Merger
Agreement shall be registered shares. There is presently no public market for
the Class B Common Stock and the shares of Class B Common Stock will be subject
to certain contractual restrictions on resale or transfer.
    As a condition to the proposed Merger, Norman A. Marcus, M.D. and A. Roger
Wiederhorn, M.D. will enter into employment agreements with Doctors Health (the
"Employment Agreements"), and between the execution of the Merger Agreement and
the Effective Date of the Merger, Norman A. Marcus, M.D. and A. Roger
Wiederhorn, M.D. shall be paid compensation by Medtrust at the same rate
proposed in the Employment Agreements which shall be reimbursed to Medtrust by
Doctors Health within five (5) days of payment of such compensation by Medtrust.
In addition, certain members of the Board of Directors of Medtrust will receive
compensation upon the consummation of the Merger Agreement in consideration of
the extensive time which they have committed to the Merger negotiations, a
description of which is set forth in the Merger Agreement. Your vote to approve
the Merger will also serve to ratify and approve these aspects of the
transaction in accordance with Section 13.1-871 of the Code of Virginia, 1950,
as amended.
    The exchange of Medtrust membership interests for Class B Common Stock
pursuant to the Merger Agreement is intended to be a tax-free reorganization for
federal income tax purposes. The Cash Consideration received by Members will,
however, be treated as taxable income. The parties have received a tax opinion
concerning this transaction, the principal provisions of which are described in
the Proxy Statement/Prospectus Supplement. Nevertheless, each Member is advised
to consult his or her own tax adviser. Details of the proposed transaction with
Doctors Health and Doctors Health Virginia as well as the registration of Class
B Common Stock are set forth in the accompanying Proxy Statement/Prospectus
Supplement

<PAGE>
and the Prospectus, which you are urged to read carefully in its entirety.
Approval of consummation of the Merger Agreement among Medtrust, Doctors Health
and Doctors Health Virginia requires the affirmative vote of more than
two-thirds of the outstanding membership interests of Medtrust.
    Your Board of Directors has unanimously approved the Merger Agreement, the
Employment Agreements and related reimbursement of salaries by Doctors Health,
and the distribution of compensation to certain members of the Board for their
negotiation efforts and believes that they are in the best interests of Medtrust
and our members. Accordingly, the Board unanimously recommends that you vote TO
APPROVE the Merger Agreement and the related transactions.
    WE HOPE YOU CAN ATTEND THE SPECIAL MEETING. WHETHER OR NOT YOU PLAN TO
ATTEND, PLEASE COMPLETE, SIGN AND DATE THE ENCLOSED PROXY CARD AND RETURN IT
PROMPTLY IN THE ENCLOSED ENVELOPE. YOUR VOTE IS IMPORTANT.
    We look forward to seeing you at the Special Meeting.
                                         Sincerely yours,

                           SUMMARY OF THE TRANSACTION
   
     THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY, AND SUBJECT TO THE
MORE DETAILED INFORMATION AND FINANCIAL STATEMENTS CONTAINED IN THIS PROXY
STATEMENT/PROSPECTUS SUPPLEMENT AND THE PROSPECTUS DATED JANUARY 24, 1997.
UNLESS OTHERWISE DEFINED HEREIN, CAPITALIZED TERMS HAVE THE MEANINGS ASSIGNED TO
THEM IN THE PROSPECTUS. SEE THE DEFINITIONS SET FORTH IN THE GLOSSARY TO THE
"PROSPECTUS."
    
PARTIES TO THE MERGER
     DOCTORS HEALTH. Doctors Health is a Maryland corporation organized in 1994
to develop and consolidate individual and groups of internists, pediatricians
and family practitioners, specialist physicians, hospitals and other health care
providers into primary care-driven, comprehensive managed care health care
delivery networks. As of January 10, 1997, the Company had approximately 1,150
Network Physicians in six regional networks throughout the state of Maryland and
one regional network in Northern Virginia, including approximately 310 PCPs, 84
obstetrician/gynecologists, and 756 specialist physicians.
     MEDTRUST. Medtrust is a Virginia non-stock membership corporation organized
in 1994 for the purpose of providing its member physician groups (the "Members")
with an appropriate vehicle for the joint marketing of medical services, the
achievement of cost savings through group purchasing and the development of a
quality marketing identity to attract managed care contracts for the benefit of
its Members. There are 213 group practices and proprietorships consisting of
nearly 450 physician providers in Northern Virginia, which are Members of
Medtrust.
     DOCTORS HEALTH VIRGINIA. Doctors Health Virginia is a Virginia corporation
incorporated in 1996 for the purpose of consummating the Merger. Doctors Health
Virginia is a wholly-owned subsidiary of Doctors Health, and no other person or
entity owns capital stock of Doctors Health Virginia.
THE MERGER; EFFECTIVE DATE
     Pursuant to the Plan and Agreement of Merger dated November 15, 1996 by and
among Medtrust, Doctors Health and Doctors Health Virginia, as amended (the
"Merger Agreement"), on the Effective Date, Medtrust will merge with and into
Doctors Health Virginia (the "Merger") at which time the separate corporate
existence of Medtrust will cease. A copy of the Merger Agreement is attached to
this Proxy Statement/Prospectus Supplement as Annex A and is incorporated herein
by reference.
     The Merger is to become effective as soon as practicable after all
approvals and events required for the Merger (including the approval of the
Members) have occurred and all conditions precedent to the Merger have been
fulfilled or waived or on such other date on which Medtrust and Doctors Health
may agree (the "Effective Date"). It is expected that the Effective Date will
occur in the first calendar quarter of 1997.
THE CONVERSION RATIO
   
     On the Effective Date of the Merger, each of the outstanding membership
interests of Medtrust will be converted into and represent the right to receive
the number of shares of Class B Common Stock and that amount of cash determined
by multiplying each of the Share Consideration and Cash Consideration by a
fraction, the numerator of which is the aggregate Initial Membership Fee paid by
the respective Member for such Member's Approved Physicians (as defined in the
Bylaws of Medtrust) and the denominator of which is the aggregate Initial
Membership Fees paid by all Members holding membership interests in Medtrust
(immediately prior to the Effective Date of the Merger) on behalf of their
Approved Physicians (the "Conversion Ratio").
    
   
     By way of example, if the initial assessments paid by a Member professional
corporation on behalf of its three approved physicians totalled $6,000 and the
aggregate of the initial assessments paid by all Members was $460,650, such
Member would receive Class B Common Stock in an amount equal to the product of
(i) 24,000 (representing the shares available pursuant to the Merger) multiplied
by (ii) the fraction the numerator of which is 6,000 and the denominator of
which is 460,650. Pursuant to the terms of the Merger Agreement, fractional
shares are to be rounded to the next highest whole share. In addition, such
Member would receive cash in an amount equal to the product of (i) 167,477.56
(less any reduction for transaction expenses) multiplied by (ii) the fraction
the numerator of which is 6,000 and the denominator of which is 460,650. As a
result, the Member in this example would receive 313 shares of Class B Common
Stock, plus $2,181.41 in cash before any reduction for transaction expenses.
    
MEETING OF MEMBERS
   
     This Proxy Statement/Prospectus Supplement is being provided to the Members
of Medtrust in connection with a Special Meeting of Members of Medtrust (the
"Special Meeting"), which is to be held at the Holiday Inn, located at 1960
Chain
    
 
<PAGE>
   
Bridge Road, McLean, Virginia 22102. Notice of the Special Meeting is being
delivered together with this Proxy Statement/Prospectus Supplement. The purpose
of the Special Meeting will be to consider and vote on a proposal to approve,
ratify and confirm the Merger Agreement, the Merger and related transactions.
    
RECORD DATE; VOTES REQUIRED
   
     Only Members of record at the close of business on January 29, 1997, will
be entitled to notice of the Special Meeting. Only Members of record at the
close of business on February 27, 1997 will be entitled to vote at the Special
Meeting or any adjournments or postponements thereof. Each Member is entitled to
that number of votes equal to the number of approved physicians credentialled by
Medtrust and employed by such Member.
    
   
     The presence in person or by properly executed proxy, of the Members
holding a majority of the votes entitled to be cast is necessary to constitute a
quorum at the Special Meeting. The directors of Medtrust have passed a
resolution declaring the Merger advisable and unanimously recommending that the
Members vote to approve, ratify and confirm the Merger Agreement and the Merger.
As of the date of the notice, the directors and executive officers of Medtrust
are affiliated with Members which hold an aggregate of 39 votes, or 8.7% of the
votes entitled to be cast at the Special Meeting. The executive officers and
directors of Medtrust do not directly own any membership interests.
    
     An affirmative vote of more than two-thirds of the issued and outstanding
votes entitled to be cast is required to approve, ratify and confirm the Merger
Agreement and the Merger.
REASONS FOR THE MERGER; RECOMMENDATIONS OF THE MEDTRUST BOARD AND APPROVAL BY
THE DOCTORS HEALTH BOARD
     The Medtrust Board of Directors believes that the Merger Agreement and the
Merger are advisable, fair to, and in the best interests of Medtrust and the
Members. In considering the terms and conditions of the Merger, the Medtrust
Board considered its financial terms, in particular that the Conversion Ratio
provides the Members with an opportunity to receive partial reimbursement for
their initial membership investment and to have an opportunity for capital
appreciation and liquidity through an investment in Class B Common Stock. Among
other things, the Medtrust Board also considered the benefits of introducing its
members to a larger corporation in a broader geographic area; the increased
access to capital to fund risk-based contracts and to enable its Members to have
access to necessary information systems and the history and business strategy of
Doctors Health. See "Proposed Merger of Doctors Health and
Medtrust -- Background of the Merger," " -- Reasons for the Merger";
" -- Recommendations of the Medtrust Board and Approval by the Doctors Health
Board". THE MEDTRUST BOARD UNANIMOUSLY RECOMMENDS THAT THE MEMBERS VOTE TO
APPROVE, RATIFY AND CONFIRM THE MERGER AGREEMENT AND THE MERGER PROVIDED FOR
THEREIN.
DISSENTERS' RIGHTS
     The holders of membership interests of Medtrust who vote against the Merger
will not receive appraisal rights or be entitled to payment of cash (other than
the Cash Consideration) for the fair value of their membership interests under
the Virginia Nonstock Corporation Act.
CONDITIONS TO CONSUMMATION
     Consummation of the Merger is subject to certain conditions, including but
not limited to (i) the execution by at least 30 primary care physicians who are
affiliated with Members of Medtrust of exclusive Independent Physician
Association agreements with Doctors Health; (ii) the effectiveness of the
Registration Statement of which this Proxy Statement/Prospectus Supplement is a
part; and (iii) Members holding more than twenty percent of the membership
interests of Medtrust shall not have voted against the consummation of the
Merger at the Special Meeting. See "Proposed Merger of Medtrust and Doctors
Health Virginia -- Conditions to Consummation of the Merger" and "The Merger
Agreement -- Conditions to the Merger."
BUSINESS OF MEDTRUST AND DOCTORS HEALTH PENDING THE MERGER
     Medtrust has agreed to conduct its business prior to the Effective Date
only in the ordinary course of business. Medtrust and Doctors Health have each
agreed to give the other party and its representatives reasonable access
throughout the period prior to the Effective Date to their respective books and
records. Effective on November 1, 1996, Medtrust and Doctors Health entered into
a Network Contracting and Management Services Agreement (the "Management
Agreement") pursuant to which Medtrust appointed Doctors Health as Medtrust's
exclusive and preferred provider of managed care contracting services including
the right to negotiate managed care contracts on behalf of Medtrust with any
Payor. In addition, Doctors Health has agreed to pay substantially all of the
operating expenses of Medtrust from November 1, 1996 to the Effective Date
                                      S-2
 
<PAGE>
and certain executive salaries from November 15, 1996 to the Effective Date. See
"Proposed Merger of Medtrust and Doctors Health Virginia -- Business of Doctors
Health and Medtrust Pending the Merger."
TERMINATION
     The Merger Agreement may be terminated by either Medtrust or Doctors Health
if the Merger is not consummated by March 31, 1997 through no fault of the party
seeking to terminate. Medtrust or Doctors Health may terminate the Merger
Agreement prior to March 31, 1997 if any other party commits a material
misrepresentation, materially breaches a covenant or warranty, or materially
fails to perform its obligations under the Merger Agreement.
INTERESTS OF CERTAIN PERSONS IN THE MERGER
     Two officers and directors of Medtrust, Norman Marcus, M.D. and Roger
Wiederhorn, M.D., will enter into employment agreements with Doctors Health upon
the consummation of the Merger. These employment agreements provide for
employment for a term of three years. In addition, at closing these two officers
and directors of Medtrust, together with Donald Colvin, M.D., Beal Lowen, M.D.,
Samuel Shor, M.D., and Ronald Bortnick, M.D., will be entitled to a pro rata
portion of 6,000 shares of Class B Common Stock and $30,000 in cash to be
divided among them in consideration of the extensive time which they have
committed to the Merger negotiations, which compensation the Medtrust Board of
Directors has determined to be fair and reasonable. See "Proposed Merger of
Doctors Health and Medtrust -- Interests of Certain Persons in the Merger."
RESALE OF CLASS B COMMON STOCK
     The shares of Class B Common Stock offered to the Members by this Proxy
Statement/Prospectus Supplement have been registered under the Securities Act.
The shares will be subject to the Stockholders Agreement attached hereto as
Annex B and, therefore, will not be freely transferable. In addition, under the
Securities Act certain additional restrictions on transfer apply to resale of
shares of the Class B Common Stock received by "affiliates" of Medtrust or
Doctors Health. There is no public market for the Class B Common Stock. See
"Resale of Class B Common Stock."
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
     It is intended that the Merger will qualify as a tax-free reorganization
for federal income tax purposes. Accordingly, (except for cash and shares of
Class B Common Stock received for services rendered by certain Medtrust Board
Members) (i) Members will not recognize taxable income or loss upon the receipt
of shares of Class B Common Stock in exchange for their Medtrust Member's
Interest by reason of the Merger, and (ii) Medtrust will not recognize taxable
income or loss by reason of the Merger. Although not a condition to the
consummation of the Merger, counsel to Medtrust has provided an opinion as to
(i) and (ii) above.Members are urged to consult their own tax advisors as to the
specific tax consequences to them of the Merger. See "Proposed Merger of
Medtrust and Doctors Health -- Certain Federal Income Tax Consequences."
COMPARATIVE RIGHTS OF MEMBERS OF MEDTRUST AND HOLDERS OF CLASS B COMMON STOCK
     The rights of Members under the Medtrust Articles of Incorporation, and
Bylaws and under the Virginia Nonstock Corporation Act differ considerably from
the rights of holders of Class B Common Stock under the Doctors Health Articles
of Incorporation and Bylaws and under the Maryland General Corporation Law. See
"Comparative Rights of Members of Medtrust and the Holders of Class B Common
Stock."

                                  RISK FACTORS
FINANCIAL PERFORMANCE OF MEDTRUST AND DOCTORS HEALTH
     Doctors Health negotiated the Share Consideration and Cash Consideration on
the basis of the presence of Medtrust's Members in a desirable geographic market
into which Doctors Health intends to expand. After the Effective Date, Doctors
Health will recruit primary care physicians to join an IPA and a Core Medical
Group in Northern Virginia. There can be no assurance that after the Effective
Date of the Merger, such recruitment will be successful, that Medtrust's
Pre-Merger relationships with its members will be beneficial to Doctors Health
and Doctors Health Virginia, that Doctors Health will be able to successfully
develop an integrated health care delivery network in Northern Virginia, or that
Doctors Health can successfully integrate Medtrust physicians into Global
Capitated Contracts. See the sections in the Prospectus "Risk Factors --
Uncertainty of Strategy; Acquisition Risks," " -- Integration of Operations,"
and " -- Dependence of the Company on Core Medical Groups and IPAs."
     Doctors Health has a limited operating history and for the fiscal year
ended June 30, 1996 and the three months ended September 30, 1996, recorded a
net loss of approximately $6.6 million and $2.8 million, respectively. Doctors
Health is likely to record a net loss for the fiscal year ending June 30, 1997.
There can be no assurance that after the Effective Date Doctors Health will earn
operating profits.
MANAGED CARE CONTRACTING
     Doctors Health does not currently have any Global Capitated Contracts with
HMOs covering patients in the state of Virginia. Doctors Health expects to
implement a Global Capitated Contract with an affiliate of Blue Cross-Blue
Shield by June 1997, pursuant to which the Company's PCPs will provide medical
services to Medicare patients in Virginia on a global capitated basis, and to
enter into a Global Capitated Contract with United Healthcare Health Plan for
commercially insured enrollees by March 1997. However, there can be no assurance
that Doctors Health will successfully implement the foregoing arrangements. See
"Risk Factors -- Dependence on Managed Care Contracts" and " -- Enrollment in
Medicare Managed Care Plans."
   
RISK FACTORS SET FORTH IN THE PROSPECTUS DATED JANUARY 24, 1997
    
     The Risk Factors set forth in the Prospectus are incorporated herein by
reference and should be read carefully by the Members.
            PROPOSED MERGER OF MEDTRUST AND DOCTORS HEALTH VIRGINIA
     The following description of the Merger does not purport to be complete and
is qualified in its entirety by reference to the Merger Agreement, a copy of
which is attached to this Proxy Statement/Prospectus Supplement as Annex A and
is incorporated herein. Medtrust Members are urged to read the Merger Agreement
in its entirety.
GENERAL
     On the Effective Date of the Merger, Medtrust will merge with and into
Doctors Health Virginia, and Doctors Health Virginia will conduct its business
pursuant to the Doctors Health Virginia Articles of Incorporation and Bylaws as
in effect immediately before the Effective Date. The separate existence of
Medtrust shall cease, and Doctors Health of Virginia shall conduct business as a
wholly-owned subsidiary of Doctors Health. Each membership interest of Medtrust
outstanding immediately prior to the Effective Date will, without any action of
the holder thereof, be canceled and converted into the number of shares of Class
B Common Stock which results after multiplication of the Conversion Ratio. No
cash will be paid in lieu of fractional shares, but all fractional shares will
be rounded up to the next highest whole share.
BACKGROUND OF THE MERGER
     The health care industry is undergoing rapid evolution, including the
consolidation of individual medical practices into larger medical groups and
independent practice associations as well as radical changes in the way
physicians are compensated for the delivery of medical services.
     In Baltimore, Maryland, Washington, D.C., Northern Virginia and surrounding
regions, physicians have increasingly become affiliated with managed care and
medical management companies such as Doctors Health which provide physicians
with certain administrative, billing, bookkeeping and budgeting services.
Companies such as Doctors Health also provide the
                                      S-4
 
<PAGE>
physician with access to Managed Care contracts and necessary tools to perform
such contracts, including state of the art disease management protocols, care
management, referral management and utilization review services. In this
environment, Doctors Health has been entering into contractual and equity
ownership relationships with primary care physicians, specialists and other
health care providers in order to develop an Integrated Health Care Delivery
System that focuses on managed care. At the same time, Medtrust has been seeking
to develop managed care contracts that provide its member primary care
physicians and specialists with access to Managed Care contracts with HMOs and
other Payors which pay its Members on a capitated or other risk basis.
     Against this backdrop, Doctors Health and the Board of Medtrust
independently reached the conclusion that developing alliances with additional
provider groups and companies focusing on the efficient delivery of health care
would enhance their abilities to respond to changing conditions in the health
care industry.
     In February of 1996, Dr. Norman Marcus, the President and Chairman of the
Board of Medtrust, Stewart B. Gold, President of Doctors Health and Dr. Scott
Rifkin, Chairman of the Board of Doctors Health, met to discuss various
strategic options, including mergers, acquisitions, strategic business
combinations and management arrangements. The parties continued discussion of
possible options and in February, Medtrust retained a law firm, Kaufman &
Canoles to provide legal advice concerning permissible transactions. Members of
Doctors Health's management conducted initial evaluations of the feasibility of
developing a relationship with Medtrust for the purpose of negotiating IPA or
Core Medical group transactions with the members and discussed potential
arrangements with the Board of Directors of Doctors Health, beginning in March,
1996.
     In March 1996, Dr. Rifkin and Mr. Gold met with Dr. Marcus to enable Dr.
Marcus to explain the discussions to the Medtrust Executive Committee. During a
subsequent meeting of the Executive Committee, the Executive Committee
authorized its representatives to continue negotiations with Doctors Health.
     During April 1996, Dr. Marcus and representatives of Doctors Health
developed a draft term sheet and presented such draft term sheet to the Medtrust
Board in April 1996. In May the Medtrust Board approved the execution and
delivery of a letter of intent. The Doctors Health Board of Directors approved
the letter of intent on May 24, 1996.
     During the summer of 1996, negotiations regarding the form of the
transaction continued at a slow pace pending the efforts of Doctors Health to
register shares of its Class B Common Stock for issuance to the Medtrust Members
among others. In July and August representatives of Doctors Health and Medtrust
met to discuss the legal structure of the transaction and decided that Doctors
Health would enter into a network contracting and service agreement to allow
Doctors Health to become the exclusive managed care contracting representative
for Medtrust pending consummation of the Merger. During the summer, due
diligence activities continued including meetings to evaluate the feasibility of
developing a Core Medical Group in northern Virginia and an Exclusive IPA.
     In October and November representatives of Doctors Health and Medtrust
drafted the Merger Agreement, the Management Agreement, and employment
agreements for Dr. Marcus and Dr. Wiederhorn. On November 19, 1996, the Medtrust
Board approved the merger and authorized Dr. Marcus to enter into the Merger
Agreement and related documents. On November 19, 1996, representatives of
Doctors Health and Medtrust executed the Merger Agreement to be effective as of
November 15, 1996, and the Management Agreement. Representatives of Doctors
Health and Medtrust then jointly developed a press release.
REASONS FOR THE MERGER
     As part of its business strategy, Doctors Health seeks to negotiate Global
Capitated Contracts by, among other things, providing Payors with established
health care delivery networks capable of providing for the delivery of medical
care to Enrollees of the HMO or other Payor. In order to accomplish this
strategy, Doctors Health seeks to establish networks throughout the Baltimore
and Washington metropolitan area, Northern Virginia and surrounding regions.
Medtrust created a non-stock membership organization of approximately 123 PCPs
and 313 specialist physicians and obtained fee-for-service medical insurance
contracts with payors, workers compensation and other vendor contracts on behalf
of the Members. Doctors Health would like to recruit substantial numbers of the
Medtrust PCPs to exclusive IPA arrangements, or membership in a Core Medical
Group. In addition, Doctors Health desires to develop and maintain non-exclusive
managed care contracting relationships with the other Medtrust physicians.
     For Doctors Health, Medtrust represents an opportunity to implement its
business plan in a market where it does not currently operate, and to earn
revenues through inclusion of Medtrust physicians in Doctors Health's Managed
Care contracts.
                                      S-5
 
<PAGE>
     For Medtrust, the Merger represents the opportunity to give its members the
opportunity to develop long-term contractual relationships with a larger entity
with more substantial financial resources than those of Medtrust. In addition,
Medtrust believes Doctors Health has established attractive practice management
services for physicians in addition to providing access to more lucrative,
Managed Care contracts. Such practice management and managed care services
include billing, bookkeeping, administrative and related services as well as
care management, utilization review and referral management services necessary
to manage the medical care of the Enrollees of the HMOs and other Payors who
contract with Doctors Health. Although Medtrust could continue to exist as an
independent IPA, it would need to conduct a substantial reorganization and
attract considerable equity or debt financing to build an infrastructure capable
of providing the services performed by Doctors Health. The Merger represents a
more immediate means to enable the Members to compete in the rapidly changing
health care industry.
APPROVAL BY THE DOCTORS HEALTH BOARD AND RECOMMENDATION OF THE MEDTRUST BOARD
DOCTORS HEALTH
     For the reasons described below, the Doctors Health Board has unanimously
approved the Merger.
     Doctors Health continuously analyzes potential acquisition candidates in
Maryland, the District of Columbia and Virginia. The Doctors Health Board of
Directors believes that the Merger is fair to and in the best interests of
Doctors Health for the reasons described below. Accordingly, the Doctors Health
Board of Directors has approved the Merger Agreement and the Merger.
     The Doctors Health Board of Directors consulted with Doctors Health
management and legal counsel. It considered the following factors to be material
to and in support of its final determination:
          (i) The Merger is expected to enable Doctors Health to take advantage
     of Medtrust's existing goodwill, infrastructure and leadership in the
     Northern Virginia market in order to establish an Integrated Health Care
     Delivery System in Northern Virginia. Such expansion of Doctors Health's
     existing network is expected to enhance Doctors Health's ability to win new
     Payor contracts and to attract additional Enrollees.
          (ii) The Merger and the efforts of Doctors Health to establish a
     Northern Virginia Integrated Health Care Delivery System are expected to
     substantially increase Doctors Health's size in terms of revenues, profits,
     physicians and locations which is expected to enhance Doctors Health's
     reputation in the Mid-Atlantic region, making it easier to attract and
     retain new physicians and win new Payor contracts.
          (iii) The Merger is expected to create in Doctors Health Virginia a
     company with a number of anticipated strengths, including the opportunity
     to develop new patient care programs in markets not currently served by
     Doctors Health and to develop additional strategies to promote higher
     quality health care.
          (iv) The Merger is expected to be treated as a tax-free
     reorganization.
     In addition to the foregoing, the Doctors Health Board of Directors
generally considered those matters discussed under "RISK FACTORS," which
included risks associated with expansion into Northern Virginia in the absence
of Global Capitated Contracts with HMOs covering patients in Northern Virginia.
The Board also considered the difficulty of establishing a network in a region
outside of its initial markets in Baltimore City, Baltimore County and
surrounding areas. The Board of Doctors Health concluded that the risks did not
outweigh the advantages of the Merger and that the Merger was in the best
interests of Doctors Health and its stockholders.
MEDTRUST
     THE BOARD OF DIRECTORS OF MEDTRUST HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT, AND RECOMMENDS A VOTE FOR THE MERGER. MEDTRUST'S BOARD OF DIRECTORS
BELIEVES THE MERGER IS FAIR AND IN THE BEST INTERESTS OF THE MEDTRUST MEMBERS.
     The material factors considered by the Medtrust Board of Directors in
reaching its conclusion to approve and recommend the Merger Agreement are as
follows:
          (i) The Medtrust Board of Directors observed the rapid changes in the
     health care industry including the continued consolidation, increasing
     competition and expansion of the prepaid segment of the health care
     industry. The Board recognized that medical practices affiliated with
     entities similar in size and resources to Medtrust were unable to achieve
     Global Capitated Contracts from HMOs and other payors. Based upon this
     review, the Medtrust Board determined that
                                      S-6
 
<PAGE>
     the Merger with Doctors Health Virginia would better position the Members
     of Medtrust because of Doctors Health's size, geographic scope and
     expertise to more effectively participate in managed care programs and to
     more profitably operate in the rapidly changing health care industry.
     Further, Doctors Health's access to capital would enable Medtrust Members
     to provide medical care under Global Capitated Contracts.
          (ii) The Medtrust Board's review of information concerning Doctors
     Health's business, prospects, historical financial performance and
     financial condition. Based on these factors, Medtrust's Board determined
     that the consideration to be received by the Members of Medtrust in the
     Merger reflected an appropriate percentage ownership of Class B Common
     Stock immediately following consummation of the Merger and that the Merger
     presented an attractive growth opportunity for the Members of Medtrust that
     could not be achieved as quickly, if at all, if the Members were to rely on
     any services that could be provided by Medtrust.
          (iii) The Medtrust Board of Directors' review of the terms of the
     Merger, including the agreement of Doctors Health to give specialist and
     primary care Members of Medtrust the opportunity to participate in any
     Integrated Health Care Delivery System established in Northern Virginia.
          (iv) The expectation that exchange of the Member Interests for the
     Class B Common Stock would be treated as a tax-free reorganization under
     the Internal Revenue Code.
     In addition to the factors described under "RISK FACTORS," the potentially
negative factors the Medtrust Board of Directors considered in connection with
its deliberation regarding the Merger were as follows:
          (i) The fact that there is no current market for the Class B Common
     Stock and there can be no assurance that Doctors Health's Common Stock will
     be listed on an exchange or other public market or that a trading market
     will develop for the Common Stock.
          (ii) Doctors Health does not have any Global Capitated Contracts
     covering medical care in Northern Virginia.
          (iii) The risk that despite the efforts of both Doctors Health and
     Medtrust, key Members may not participate in Doctors Health's Core Medical
     Groups or IPAs subsequent to the Merger. The Medtrust Board of Directors
     believed this risk was mitigated by the expertise of Doctors Health
     management and by the condition to closing that certain Directors of
     Medtrust would serve as Directors of Doctors Health Virginia.
     The Medtrust Board of Directors developed the Conversion Ratio and
determined that the Share Consideration, Cash Consideration and Conversion Ratio
were fair and in the best interests of the Members. The Medtrust Board
determined that the most appropriate method of allocating the Share
Consideration and Cash Consideration was to distribute such consideration on a
pro rata basis taking into account the Members' initial membership fees even
though the Members had been promised and expected no return of their initiation
fees and annual dues upon joining Medtrust. Thus, the Board determined that the
Conversion Ratio should consist of a fraction the numerator of which is the
Members' initial membership fee and the denominator of which is the total
initial membership fees paid by all Members and concluded that this formula was
fair to the Members.
     In considering whether the Merger was in the best interests of the Medtrust
Members, the Medtrust Board concluded that any compensation to be paid to
certain directors and officers of Medtrust was fair and reasonable in light of
the time and resources committed by these individuals in analyzing and
negotiating the transactions and that such compensation would not materially
decrease the Merger consideration paid to the Members. In addition, the Medtrust
Members believed that the Merger would have no material adverse effects on any
Medtrust Members. For a discussion of the Medtrust Board of Directors' analysis
of the interests of certain persons in the Merger, including its chairman, Dr.
Norman Marcus, see "Proposed Merger of Medtrust and Doctors Health
Virginia -- Interests of Certain Persons in the Merger."
     The foregoing discussion of the information and factors considered is not
intended to be exhaustive, but it does include all material factors considered
by the Medtrust Board of Directors. In view of the wide variety of information
and factors, both positive and negative, considered by the Medtrust Board, the
Board did not find it practicable to and did not quantify or otherwise assign
relative weights to the specific factors considered and individual Directors may
have given differing weights to different factors.
     The Medtrust Board of Directors did not seek or obtain a fairness opinion
from an independent party and determined that such assistance was not necessary
in its evaluation of the Merger. After taking into consideration all of the
factors set forth above including (i) Doctors Health's financial condition and
prospects, (ii) the rapid changes in the health care industry, and (iii) the
amount of the Merger consideration and additional business transactions that may
be entered into between

<PAGE>
serve as Vice President of Network Development of Doctors Health for an annual

President for an annual compensation of $36,650. The effectiveness of each
Employment Agreement is conditioned upon completion of the Merger. The term of
each Employment Agreement is three years, commencing on the Effective Date of

     Pursuant to these employment agreements, each of the executives has agreed
to maintain the confidentiality of certain information pertaining to the
businesses of Doctors Health. The employment agreements contain certain
non-competition provisions in the event the executive's employment is terminated
during its term by Doctors Health or the executive without cause. For one year
after such termination, each executive has agreed not to accept employment from
an integrated health care delivery system in Northern Virginia which engages in

similarly situated employees of Doctors Health.
     Pursuant to the Management Agreement between Doctors Health and Medtrust,

CERTAIN FEDERAL INCOME TAX CONSEQUENCES
   
     The following discussion of the material federal income tax consequences of
the Merger and the exchange by the Medtrust Members of their interest in
Medtrust for shares of Class B Common Stock has been prepared in accordance with
applicable disclosure regulations. Each Member's individual circumstances may
affect the tax consequences of the Merger to such Member. In addition, no
information is provided herein with respect to the tax consequences of the
Merger under applicable foreign, state or local laws. This discussion assumes
the Medtrust Members hold their Members' Interests as capital assets within the
meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the
"Code"). ACCORDINGLY, EACH MEDTRUST MEMBER IS ADVISED TO CONSULT SUCH MEMBER'S
OWN TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO SUCH
MEMBER.
    
     In the opinion of Kaufman & Canoles, counsel to Medtrust, the Merger will
constitute a tax-free reorganization under Section 368(a) of the Code, and
Doctors Health, Doctors Health Virginia and Medtrust will each be a party to the
reorganization within the meaning of Section 368(b) of the Code.
     In rendering such opinion, counsel has relied upon the facts that are
described herein, upon certain customary representations made by the management
of Medtrust and by the management of Doctors Health and upon certain
assumptions. Such opinion is also based upon the Code, regulations currently in
effect thereunder, current administrative rulings and practice by the Service,
and judicial authority, all of which are subject to change. Any such change
could affect the continuing validity of such opinion and this discussion. No
ruling has been sought from the Internal Revenue Service as to the federal
income tax consequences of the Merger, and the opinion of counsel is not binding
on the Internal Revenue Service or any court.
     As a tax-free reorganization, the Merger will have the following federal
tax consequences for the Members and Medtrust (except for cash and shares of
Class B Common Stock received for services rendered by certain Medtrust Board
Members):
     (i) No gain or loss will be recognized by Medtrust as a result of the
Merger;
     (ii) No gain or loss will be recognized by a Medtrust Member with respect
to shares of Class B Common Stock received from Doctors Health in exchange for
Medtrust Member Interests;
     (iii) The tax basis of the shares of Class B Common Stock received by a
Medtrust Member will be equal to the aggregate tax basis of the Medtrust
Interests exchanged therefor; and
                                      S-10
 
<PAGE>
     (iv) The holding period of the shares of Class B Common Stock received by a
Medtrust Member will include the holding period or periods of the Medtrust
Member Interest exchanged therefor.
     The foregoing discussion is intended only as a summary of the material
federal income tax consequences of the Merger and does not purport to be a
complete analysis or listing of all potential tax effects relevant to a decision
whether to vote in favor of approval and adoption of the Merger Agreement. The
discussion does not address the tax consequences arising under the laws of any
state, locality or foreign jurisdiction. Holders of Medtrust Member Interests
are urged to consult their own tax advisors concerning the federal, state, local
and foreign tax consequences of the Merger to them.

     After the Effective Date, Doctors Health Virginia will (i) seek to preserve

Board of Directors of Medtrust for the Special Meeting.
   
     The Special Meeting will be held at the Holiday Inn, 1960 Chain Bridge
Road, McLean, Virginia 22102 on February 27, 1997 at 7:00 p.m. local time. Only
Members of record at the close of business on January 29, 1997 will be entitled
to notice of the Special Meeting. Only Members of record at the close of
business on February 27, 1997 will be entitled to vote at the Special Meeting.
As of the date of the notice of the Special Meeting, the Medtrust Members are
entitled to 448 votes. Each Member is entitled to such number of votes equal to
the number of Approved Physicians employed by such Member. Any proxy given may
be revoked by a Member at any time prior to its exercise. Such right of
revocation is not limited or subject to compliance with any formal procedure.
    
     Doctors Health will pay the costs of printing and mailing this Proxy
Statement/Prospectus Supplement. Doctors Health will pay all other expenses
which it may incur in the solicitation of proxies. Doctors Health will pay the
filing fees in respect
                                      S-14

VOTES REQUIRED
     The affirmative vote of more than two-thirds of the outstanding member
interests of Medtrust will be required to approve, ratify and confirm the Merger
Agreement and the Merger provided for therein. Because the required vote of
Members on the Merger Agreement and the Merger is based upon the total number of
eligible votes of Members, the failure to submit a proxy card (or the failure to
vote in person at the Special Meeting), and the abstention from voting will have
the same effect as a vote against the Merger Agreement and the Merger. As of
December 17, 1996 the directors and executive officers of Medtrust and certain
related persons as a group owned beneficially through their respective
professional corporations 39 votes out of 448 votes, representing 8.7% of the
votes entitled to be cast on the Record Date.
     All member interests of Medtrust represented by properly executed proxies
will, unless such proxies have been previously revoked, be voted in accordance
with the instructions indicated in such proxies. If no instructions are
indicated, such member interests of Medtrust represented by such proxies will be
voted to approve, ratify and confirm the Merger Agreement and the Merger
provided for therein.
DISSENTERS' RIGHTS
     Holders of member interests in Medtrust who dissent and vote against the
Merger Agreement and the Merger will not receive appraisal rights or be entitled
to the payment in cash of the fair value of their member interests under the
VNCA. See "Comparative Rights of Members of Medtrust and the Holders of Class B
Common Stock -- Dissenters' Rights."
                           BUSINESS OF DOCTORS HEALTH
     The business of Doctors Health is described in the Prospectus.
                              BUSINESS OF MEDTRUST
     Medtrust was incorporated on May 3, 1994 as a non-stock membership
corporation under the laws of the Commonwealth of Virginia for the purpose of
providing its Members with an appropriate vehicle for the joint marketing of
medical services, the achievement of cost savings through group purchasing and
the development of a quality marketing identity to attract managed care
contracts for the benefit of its Members in the Northern Virginia marketplace.
The initial Members of Medtrust consisted largely of specialty medical practice
groups located within Fairfax County, Virginia and certain adjacent Northern
Virginia communities and was quickly expanded to recruit to its membership
primary care physician groups and hospital based providers to permit Medtrust to
market a full range of medical services to local employers and third party
payors. Medtrust leadership engaged in active recruiting of Members and
succeeded in recruiting over 200 physician group practices and proprietorships
consisting of a total of more than 400 physician providers in the Northern
Virginia marketplace.
     Medtrust is governed by a Board of Directors consisting of eleven
individual physicians elected by a plurality vote of the Members. Each Member is
entitled to that number of votes equal to the number of approved physicians
employed by the group. The approved physicians constitute individuals who have
been credentialed by Medtrust for the provision of professional services to the
beneficiaries of health benefit plans which choose to contract with Medtrust. In
addition to the Board of Directors of eleven physicians, a Board of Governors
appointed by the Board of Directors advises the Board and makes policy
recommendations on credentialling, quality assurance and contracting issues. The
Board of Governors consists of at least one representative from each
subspecialty practice area.
     Medtrust was funded by the initial capital contributions of each of the
Members which contributions ranged from a high of $2,500 per approved physician
for specialty physician groups to a low of $300 per approved physician for
primary care physician groups. In addition, the Board of Directors assessed dues
as necessary to fund the ongoing operations of Medtrust.
     The formation of Medtrust was in response to industry trends which
included, among other factors, increased penetration of managed care, demand by
third party payors for effective quality assurance and utilization review
protocols within participating physician practices, the need to reduce costs and
consolidate services in order to maintain profit margins, and
                                      S-15
 
<PAGE>
increased selectivity by third party payors in the selection of their provider
panels. In response to these industry trends, physicians in a number of
communities throughout the country have joined together to form marketing
entities which require less integration and expense of organization than the
traditional merger of independent practices. These loosely structured physician
organizations, sometimes known as "networks" or "messenger models" within
industry parlance, have been useful for their member providers by offering to
these providers a vehicle by which discounts can be negotiated on the purchase
of supplies and medical malpractice insurance can be purchased at reduced group
rates and by permitting the retention of marketing personnel for the purpose of
seeking contracting opportunities that would expand the patient populations of
the constituent groups and improve their payor mix to include higher paying
commercial customers. The effectiveness of the network model has been somewhat
limited by legal constraints which prohibit joint decision making and collective
price negotiation on fee for service contracts. Medtrust has been successful in
achieving purchasing discounts on medical malpractice insurance and other vendor
contracts for its Members. As of December 1996, Medtrust had successfully
procured on behalf of its Members fee-for-service, provider contracts covering,
on a non-exclusive basis, an aggregate of approximately 77,000 covered lives
with Dimensions Health Network, Inc., John Hancock Mutual Life Insurance
Company, Med Eval, Inc., Qual Choice of Virginia, NYLCARE Passport PPO, and
Preferred Health Network. During fiscal year 1996, Medtrust received no
compensation for negotiating such contracts.
     Since the operations of Medtrust have been funded by Member contributions
and the assessment of dues and Medtrust has no other significant source of
revenue, Medtrust has actively sought strategic partners to provide the capital
necessary to expand its marketing activities and to accept risk under capitated
contracts. The merger of Medtrust with Doctors Health is expected to provide the
Medtrust members with this strategic relationship. Medtrust management believes
that because physicians are positioned to control treatment protocols and the
efficient utilization of the health care dollar, physician-driven capitation
models are uniquely positioned to compete in the marketplace if adequate capital
is available to purchase the requisite information systems and to provide the
reserves for operations necessary to undertake risk contracts. Although other
physician networks may exist within the Northern Virginia marketplace,
Medtrust's management believes that the prominence of its Members and the
quality of Medtrust's marketing efforts, have allowed Medtrust a pre-eminent
position in the marketplace. Nonetheless, Medtrust's ability to obtain new
contracts is somewhat limited by the inability to coordinate delivery of
hospital services and ancillary services with the professional component and the
lack of experience of third party payors negotiating with and integrating
provider networks.
     Medtrust's principal assets include office equipment and fee-for-service
contracts with third party Payors as described herein. Medtrust has two
principal employees responsible for office administration and membership
recruitment.
     Medtrust's general business purpose is to provide its Members increased
contracting efficiency through group contracting with HMOs or other Payors and
by obtaining certain economies of scale with respect to marketing and
purchasing. Medtrust's revenues consist almost exclusively of dues and initial
assessments paid by its Members and its expenses consist primarily of employee
compensation, marketing and consulting fees and office rental costs. Annual dues
and assessments generally match annual expenses. Therefore, Medtrust does not
attempt to operate at a profit or to create equity value for its Members.
Moreover, the Medtrust Members had no expectation of receiving any capital
appreciation on their initial assessment. For this reason, management of
Medtrust does not believe that a presentation of historical financial statements
for Medtrust and an analysis of historical financial information of Medtrust
would be meaningful.
     There are four classes of voting members with membership in any class to be
determined by the credentialling committee of Medtrust in accordance with the
applicant's primary area of specialty or location of practice. The Board of
Directors may determine from time to time an initial membership fee and set such
other fees, dues and assessments for membership as the Board of Directors
determines appropriate in its sole discretion. Class A consists of 94 surgical
specialist members with 166 approved physicians whose initial membership fee
ranged from $1,000 to $2,500. Class B consists of 53 medical specialist members
with 121 approved physicians whose initial membership fee ranged from $300 to
$1,500. Class C consists of 60 primary care members with 122 approved physicians
whose initial membership fee ranged from $250 to $300. Class D consists of 6
hospital based members with 39 approved physicians whose initial membership fee
was $500. See "Comparative Rights of Members of Medtrust and the Holders of
Class B Common Stock" for a summary description of the voting rights and other
rights of Medtrust Members.

           COMPARATIVE RIGHTS OF MEMBERS OF MEDTRUST AND THE HOLDERS
                            OF CLASS B COMMON STOCK
     The rights of members of Medtrust currently are governed by the Virginia
Nonstock Corporations Act ("VNCA"), Medtrust's Articles of Incorporation, and
the Medtrust Bylaws. Upon consummation of the Merger, Medtrust Members will
become stockholders of Doctors Health, which is a Maryland corporation. Their
rights as stockholders of Doctors Health will be governed by the Maryland
General Corporation Law ("MGCL"), Doctors Health's Articles of Incorporation,
and Doctors Health's Bylaws. The following is a summary comparison of the
material differences in the rights of Members of Medtrust
                                      S-17
 
<PAGE>
and of holders of Doctors Health Class B Common Stock under governing provisions
of their constituent documents and the VNCA and the MGCL. This summary does not
purport to be a complete discussion of, and is qualified in its entirety by
reference to, the VNCA, the MGCL, and the constituent documents of Medtrust and
Doctors Health.
CAPITAL AND CORPORATE STRUCTURE
     MEDTRUST. Medtrust is a nonstock corporation and as such has no authorized
capital stock. Its Bylaws provide for the following four classes of voting
members: (1) Class A, Surgical Specialists; (2) Class B, Medical Specialists;
(3) Class C, Primary Care Physicians; and (4) Class D, Hospital Based
Physicians. Eligibility for membership in any class is determined by the
Credentialling Committee (a committee of the Board) in accordance with the
applicant's primary area of specialty or location of practice. Election of
members of a particular class is made from time to time by the Board upon
recommendation of the Credentialling Committee. Members of each class are
entitled to such rights to use the facilities and property of Medtrust and such
other rights as shall be established from time to time by resolution of the
Board.
     Medtrust Members do not have many of the rights commonly associated with
security ownership. For example, Members have no rights to receive dividends or
liquidation distributions. Membership interests are non-transferable and cease
to exist upon the death or liquidation of the member. The Medtrust Bylaws and
the VNCA expressly state that Members have no property interests in their
membership or in any of their rights of membership.
     DOCTORS HEALTH. Doctors Health's authorized capital stock and the relative
rights of the various classes of stock are set forth under "Description of
Capital Stock" in the Prospectus.
VOTING RIGHTS
     MEDTRUST. Pursuant to Medtrust's Bylaws, Members may vote on matters
presented to the membership by casting that number of votes equal to the number
of Approved Physicians who are employed by the Member. An "Approved Physician"
is a physician who has been authorized by the Credentialling Committee to
perform services under the Member's provider contract with Medtrust. Unless
otherwise provided by resolution of the Board of Directors, Medtrust Members do
not vote separately by class. Fifty percent (50%) of the voting power of the
corporation is required to be represented at a membership meeting either in
person or by proxy in order to constitute a quorum. The Medtrust Bylaws provide
that no cumulative voting is permitted with respect to the election of directors
and the articles of incorporation do not provide for cumulative voting. The VNCA
states that there is no cumulative voting for the election of directors unless
the articles of incorporation so provide.
     In general, Members may vote in person or by proxy. However, the Bylaws
provide that, unless the proxy refers to the general nature of the matter upon
which the vote will be cast, votes may not be made by proxy with respect to the
following issues: (i) the removal of a director or directors without cause; (ii)
filling of vacancies on the Board of Directors not otherwise filled by the
Board, (iii) approval of transactions involving a director having a material
financial interest; (iv) amendment of the Articles of Incorporation or Bylaws
repealing, restricting, creating or expanding proxy rights; (v) amendment of the
Articles of Incorporation; (vi) sale, lease, conveyance, exchange, transfer or
other disposal of all or substantially all of the corporation's assets when such
transaction is not in the usual and regular course of business, (vii) approval
of merger terms; (viii) amendment of agreement of merger; and (ix) election to
dissolve the corporation.
     Pursuant to the VNCA, Medtrust members must approve a plan of merger after
recommendation of approval by the Board of Directors. A plan of merger must be
approved by each voting group entitled to vote on the plan by more than two-
thirds of all the votes cast on the plan by that voting group at a meeting at
which a quorum of the voting group exists. A sale of all or substantially all of
the corporation's assets other than in the regular course of business also must
be approved by more than two-thirds of all the votes cast on the transaction at
a meeting at which a quorum exists. The VNCA provides that members must approve
amendments to the company's articles of incorporation by each voting group
entitled to vote on the proposed amendment by more than two-thirds of all the
votes cast on the amendment by that voting group at a meeting at which a quorum
of the voting group exists. The VNCA does not require the members of a surviving
corporation to vote on a merger if (i) the merger agreement does not amend the
existing articles of incorporation such that the amendment would otherwise
require shareholder approval; and (ii) each member of the surviving corporation
will retain the identical designation, preferences, limitations, and relative
rights, immediately after the effective date of the merger as held before.
     DOCTORS HEALTH. In general, under the Doctors Health Articles of
Incorporation, each holder of Class B Common Stock is entitled to cast, in
person or by proxy, one vote for each share of Class B Common Stock held of
record by such holder on all matters to be voted on by stockholders. The holders
of Class B Common Stock generally vote together with holders of all
                                      S-18
 
<PAGE>
other classes and series of stock of Doctors Health and not as a separate class
or series, except where specifically provided. The Doctors Health Bylaws provide
that a quorum at a stockholders' meeting consisting of the presence in person or
by proxy of stockholders entitled to cast two thirds of the votes thereat.
Two-thirds of the votes cast at a meeting of stockholders, duly called and at
which a quorum is present, shall be sufficient to take or authorize action upon
any matter, other than the election of directors, which may properly come before
the meeting, including the approval of a plan of merger or the sale of all or
substantially all of the assets of the corporation.
     With respect to the election of directors, the holders of Class B Common
Stock, voting as a single class, are entitled to elect eight directors to the
Board ("Class B Common Director") The affirmative vote of a majority of the
shares of Class B Common Stock represented in person or by proxy at a meeting at
which a quorum of Class B Common Stock is present shall be sufficient to approve
any matter with respect to which said holders are entitled to vote; provided,
however, that the affirmative vote of a plurality of all votes cast shall be
sufficient to elect a Class B Common Director. Each share of Class B Common
Stock may be voted for as many individuals as there are Class B Common Directors
to be elected. The holders of Class B Common Stock, at any annual meeting or
upon a call of a special meeting of holders of Class B Common Stock by holders
of not less than 25% of the shares of Class B Common Stock then outstanding, may
remove any Class B Common Director at any time and from time to time with or
without cause, voting as a single class, by the affirmative vote of a majority
of all of the votes entitled to be cast for the election of a Class B Common
Director, and may elect a successor to fill any resulting vacancies for the
remainder of the term of such director. If any Class B Common Director shall
cease to be a director for any reason (including death, resignation, removal or
any other cause), the vacancy shall be filled by a vote of the remaining Class B
Common Directors (unless, with respect to removal, the holders of Class B Common
Stock have elected a successor Class B Common Director pursuant to the removal
process provisions). If there are no such remaining directors, then upon a call
of a special meeting of holders of Class B Common Stock, by any such holder, the
vacancy shall be filled by the vote of the holders of Class B Common Stock,
voting as a single class.
     The MGCL does not require a stockholder vote of the surviving corporation
in a merger if the merger does not amend the surviving corporation's Articles of
Incorporation or change its outstanding stock and the number of shares to be
issued by the surviving corporation in the merger does not exceed 15% of the
shares outstanding immediately before the merger becomes effective.
     The Articles of Incorporation of Doctors Health provide that, subject to
certain rights of preferred stockholders, the corporation reserves the right to
make, from time to time, any amendments to the Articles of Incorporation,
including any amendments which alter the contract rights of any holder of a
class of outstanding stock as expressly set forth in the charter.
DISSENTER'S RIGHTS
     MEDTRUST. Under the VNCA, a Member who dissents from the corporation taking
certain actions such as a merger or a consolidation which are subsequently
approved and consummated does not have any rights to receive consideration other
than what such Member would receive pursuant to the transaction.
     DOCTORS HEALTH. Pursuant to the MGCL, a stockholder who dissents from
certain reorganizational transactions may, under varying circumstances, receive
cash in the amount of the fair value of his or her shares (as may be ultimately
determined by a court) in lieu of the consideration he or she would otherwise
receive in any such transaction. However, the MGCL also provides that a
stockholder does not have appraisal rights in a merger or consolidation if such
stockholder's stock is listed on a national exchange or is designated as a
security listed on the The Nasdaq National Market or if such stockholder's stock
is that of the surviving corporation in the merger and the merger does not alter
or change such stock.
DIRECTORS
     MEDTRUST. Medtrust's Bylaws presently provide that the Board of Directors
shall consist of that number of directors fixed by resolution of the Board
between five and 22 in number. The initial directors presently serving have
terms scheduled to end in 1997, 1998 and 1999. Upon the expiration of these
initial terms, the directors elected to fill the vacancies would all have three
year terms resulting in staggered terms. The Board of Directors of Medtrust
generally has all of the corporate power of the corporation and has the
authority to control all of its business and affairs, including the right to
levy dues and assessments and appoint officers and agents. By resolution, the
Board may delegate power and responsibility to committees, officers and agents.
To qualify to serve as a director of Medtrust an individual must be an Approved
Physician and must be employed by a Member of Medtrust. No physician who is
employed by a Class D member is eligible to serve as a director unless he or she
has been previously authorized by resolution of the Board of Directors. So long
as there are at least 100 physicians who are
                                      S-19
 
<PAGE>
employed by Class C members, no more than 50% of the directors on the board may
be physicians employed by Class A or B members.
     DOCTORS HEALTH. The Articles of Incorporation of Doctors Health provide
that, until the 1998 annual stockholders meeting, there shall be 18 directors of
which five directors shall be directors elected by Class A stockholders, eight
shall be elected by Class B stockholders, two shall be elected by Series A
Preferred Stockholders, two shall be elected by Series B Preferred Stockholders
and one shall be elected by Series C Preferred stockholders. The number of
directors will increase to 19 after the 1998 annual Stockholders meeting at
which time the Series C Preferred Stockholder shall have the right to elect two
directors. The number of directors comprising the Board of Directors and the
number of directors to be elected by each class of stock may not be changed
except by an amendment to the Articles of Incorporation approved by the vote of
stockholders entitled to vote at least two-thirds of the shares of each class of
the capital stock that is to be affected by the amendment.
STOCKHOLDER POWER TO CALL A SPECIAL MEETING
     MEDTRUST. Pursuant to the Medtrust Bylaws, special meetings of the
membership may be called by the Chairman of the Board, the President, the Board
of Directors, or by one or more members constituting five percent (5%) or more
of the voting power of the corporation.
     DOCTORS HEALTH. Under the MGCL and the Doctors Health Bylaws, the Board of
Directors, the Chairman of the Board, the president or the holders entitled to
cast at least two-thirds of all of the votes entitled to be cast at the meeting
may call a special meeting of the stockholders.
NOTICE OF MEETINGS
     MEDTRUST. Under the VNCA and the Medtrust Bylaws, members are to be given
written notice of the date, time and place of each annual and special members
meeting. Such notice shall be given no less than 10 nor more than 60 days before
the date of the meeting. In the case of a special meeting called for the purpose
of acting on an amendment to the Articles of Incorporation, a plan of merger, or
a proposed sale of all or substantially all of the assets of the corporation,
the VNCA requires that notice be given not less than 25 nor more than 60 days
before the date of the meeting.
     DOCTORS HEALTH. Pursuant to the Bylaws of Doctors Health, notice of the
time, date and place of each annual or special meeting shall be given at least
10 but not more than 90 days prior to the date of the meeting.
INSPECTION OF STOCKHOLDER OR MEMBER LISTS
     MEDTRUST. Under the VNCA, Medtrust members may inspect a list of Medtrust
members during the ten days prior to a membership meeting during regular
business hours. Such list shall also be produced and kept open at the time and
place of the meeting.
     DOCTORS HEALTH. Under the MGCL, holders of common stock only may inspect
stockholder lists if such stockholder has been a stockholder of record for at
least six months and owns 5% of the outstanding stock of the corporation,
provided that the appropriate request is made.
INDEMNIFICATION
     MEDTRUST. Under the VNCA, a corporation may indemnify a director against
liability if the director (1) conducted himself in good faith, (2) believed that
his official conduct was in the best interests of the corporation and all other
non-official conduct was not opposed to the corporation's best interests, and
(3) in the case of a criminal proceeding, had no reasonable cause to believe his
conduct was unlawful. A corporation may not indemnify a director in connection
with a proceeding in which the director is adjudged liable on the basis that he
received an improper personal benefit. A director also cannot be indemnified in
connection with a proceeding by or in the right of the corporation in which the
director is adjudged liable to the corporation. However, in such a proceeding
the liability of the director is limited to reasonable expenses incurred in
connection with the proceeding. To the fullest extent permitted by the VNCA, the
Medtrust Articles of Incorporation provide that the corporation shall indemnify
all directors and officers of Medtrust.
     DOCTORS HEALTH. Under the MGCL, a corporation may indemnify any director,
officer, or agent made a party to any proceeding by reason of service in that
capacity unless: (i) the act or omission of the director, officer or agent was
material to the matter giving rise to the proceeding, and was committed in bad
faith or was the result of active and deliberate dishonesty; (ii) the director,
officer, or agent actually received an improper personal benefit; and (iii) in a
criminal proceeding, the
                                      S-20
 
<PAGE>
director, officer, or agent had reasonable cause to believe that the act or
omission was unlawful. However, in a proceeding by or in the right of the
corporation, indemnification may not be made in respect of a proceeding in which
the director, officer, employee or agent shall have been adjudged to be liable
to the corporation. Doctors Health's Articles of Incorporation indemnify former
and current directors and officers against any and all liabilities and expenses
incurred in connection with their services in such capacities to the maximum
extent permitted under the MGCL. The Articles of Incorporation further provide
that the Board of Directors may approve indemnification by the corporation for
officers, employees, agents and persons who serve and have served, at the
request of Doctors Health, as a director, officer, partner, trustee, employee or
agent of another corporation, partnership, joint venture or other enterprise as
may be determined by the Board.
BUSINESS COMBINATION AND AFFILIATION STATUTES
     MEDTRUST. The VNCA has no provisions relating to "affiliated transactions."
     DOCTORS HEALTH. The MGCL imposes conditions and restrictions on certain
"business combinations" (including among other various transactions, a merger,
consolidation, share exchange, or, in certain circumstances, an asset transfer
of issuance of equity securities) between a Maryland corporation and any person
who beneficially owns at least 10% of the corporation's stock (an "Interested
Stockholder"). Unless approved in advance by the board of directors, or
otherwise exempted by the statute, such a business combination is prohibited for
a period of five years after the most recent date on which the Interested
Stockholder became an Interested Stockholder. After such five-year period, a
business combination with an Interested Stockholder must be: (a) recommended by
the corporation's board of directors; and (b) approved by the affirmative vote
of at least (i) 80% of the corporation's outstanding shares entitled to vote and
(ii) two-thirds of the outstanding shares entitled to vote which are not held by
the Interested Stockholder with whom the business combination is to be effected,
unless, among other things, the corporation's common stockholders receive a
"fair price" (as defined in the statute) for their shares and the consideration
is received in cash or in the same form as previously paid by the Interested
Stockholder for his shares. Under its Articles of Incorporation and in
accordance with the MGCL, Doctors Health elected not to be governed by the
MGCL's limitations and restrictions on "business combinations."
CONTROL SHARE ACQUISITION STATUTES
     MEDTRUST. There are no provisions under the VNCA governing control share
acquisitions.
     DOCTORS HEALTH. Under the MGCL's control share acquisition law, voting
rights of shares of stock of a Maryland corporation acquired by an acquiring
person at ownership levels of 20%, 33-1/3% and 50% of the outstanding shares are
denied unless conferred by a special stockholder vote of two-thirds of the
outstanding shares held by persons other than the acquiring person and officers
and directors of the corporation or, among other exceptions, such acquisition of
shares is made pursuant to a merger agreement with the corporation or the
corporation's Articles of Incorporation or by-laws permit the acquisition of
such shares prior to the acquiring person's acquisition thereof. Unless a
corporation's charter or Bylaws provide otherwise, the statute permits such
corporation to redeem the acquired shares at "fair value" if the voting rights
are not approved or if the acquiring person does not deliver a "control share
acquisition statement" to the corporation on or before the tenth day after the
control share acquisition. The acquiring person may demand a stockholder's
meeting to consider authorizing voting rights for control shares subject to
certain disclosure obligations and payment of certain costs. If voting rights
are approved for more than fifty percent of the outstanding stock, objecting
stockholders may have their shares appraised and repurchased by the corporation
for cash. Under its Articles of Incorporation and in accordance with the MGCL,
Doctors Health elected not to be governed by the control share acquisition
statute.
                         RESALE OF CLASS B COMMON STOCK
     The shares of Class B Common Stock of Doctors Health offered by this Proxy
Statement/Prospectus Supplement have been registered under the Securities Act,
allowing Members of Medtrust who are not "affiliates" of Doctors Health or
Medtrust (as defined under the Securities Act, but generally including
directors, certain executive officers, and 10% or more stockholders of Doctors
Health or Medtrust) to trade them freely and without restriction under the
Securities Act except as limited by certain contractual restrictions set forth
in the Stockholders Agreement or otherwise. Each Member of Medtrust who may be
deemed an "affiliate" of Doctors Health will be subject to certain limitations
imposed by the Securities Act, and the rules, regulations and releases
promulgated thereunder, with respect to the sale or other disposition of the
shares of Class B Common Stock to be received by the "affiliate" pursuant to the
Merger. This Proxy Statement/Prospectus does not cover any resales of Class B
Common Stock received by affiliates of Medtrust.
                                      S-21
 
<PAGE>
     In addition to restrictions on resale that may be imposed on "affiliates"
under the Securities Act, the shares of Class B Common Stock of Doctors Health
received by the Members of Medtrust (whether or not they are deemed to be
"affiliates") pursuant to the Merger are and will be subject to the terms of
Doctors Health's Stockholders Agreement (a copy of which is attached hereto as
Annex B) which provides significant contractual restrictions on the resale of
such Common Stock until an initial public offering for cash of the Common Stock
of Doctors Health or other event constituting a "change in control" of Doctors
Health. The Stockholders Agreement provides that the signatories may sell and
transfer the stock of the Company held by them only pursuant to such agreement.
The Stockholders Agreement contemplates that Doctors Health may redeem shares of
the Class B Common 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 forth in the Stockholders Agreement.
Individual stockholders may in certain circumstances make estate planning
transfers for the benefit of themselves or family members on certain conditions.
     Under the Stockholders Agreement, in the event of an "Involuntary Transfer"
or the death or disability of a Management Stockholder, the purchaser of the
stock and the transferring stockholder may agree on the purchase price of the
stock to be sold in such event. If the parties cannot agree on a price, the
price shall be the fair market value of the stock, as determined by a jointly
selected appraiser, as of the last day of the calendar month immediately
preceding the event giving rise to the purchase of the stock, in accordance with
the procedures set forth in the Stockholders Agreement. In the event of a
"Voluntary Transfer", the purchase price to be paid by the other stockholders or
Doctors Health, if they exercise their options to purchase the stock, will be
the price at which the stockholder proposes to transfer his stock to the
proposed third party transferee.
                                 LEGAL MATTERS
     The validity of the Securities offered hereby have been passed upon for the
Company by Venable, Baetjer and Howard, LLP, Baltimore, Maryland.

IV.                      CONVERSION OF MEMBERSHIP INTERESTS
     A. CONVERSION OF MEMBERSHIP INTERESTS. The manner and basis of converting
the membership interests of Medtrust shall be as follows:
          1. Subject to the provisions of paragraphs (c) and (d) below, the
     Members of Medtrust shall receive in the aggregate 24,000 shares (the
     "Share Consideration") of DHS Class B common stock, no par value per share
     (the "DHS Common Stock") plus an aggregate amount of cash equal to $120,000
     plus the amount of cash or cash equivalents held by Medtrust as of the date
     hereof (the "Cash Consideration").
          2. Subject to the provisions of paragraphs (c) and (d) below, each
     membership interest of the Members of Medtrust outstanding immediately
     prior to the Effective Time will be converted into and represent the right
     to receive the number of shares of DHS Common Stock and that amount of cash
     determined by multiplying each of the Share Consideration and the Cash
     Consideration by a fraction, the numerator of which is the aggregate
     Initial Membership Fee paid by the respective Member for its Approved
     Physicians (as defined in the Bylaws of Medtrust) and the denominator of
     which is the aggregate Initial Membership Fees paid by all Members then
     holding membership interests in Medtrust on behalf of their Approved
     Physicians (the "Merger Consideration"). For purposes hereof, Initial
     Membership Fee shall include only the initial membership fees paid by a
     Member and shall expressly exclude any ongoing dues or assessments paid by
     a Member in support of the operational expenses of Medtrust.
          3. In the event that DHS changes the number of shares of DHS Common
     Stock issued and outstanding after the date hereof and prior to the
     Effective Time as a result of a stock split, stock dividend,
     recapitalization or other similar transaction, the Share Consideration
     shall be proportionately adjusted.
          4. No certificates for fractions of shares of DHS Common Stock and no
     scrip or other certificates evidencing fractional interests in such shares
     shall be issuable and any such fractional share which would otherwise be
     issued shall be rounded to the next highest whole share.
          5. At the Closing, DHS shall deliver to counsel for Medtrust the
     original of all certificates of DHS Common Stock to be issued as part of
     the Share Consideration together with the Cash Consideration in immediately
     available funds. Such certificates shall then be forwarded by regular mail
     with appropriate checks for the Cash Consideration to the address of record
     of each Member.
          6. At any time prior to the mailing of the notice of the Special
     Meeting, the Board of Directors may revise the method of allocation of the
     Share Consideration and Cash Consideration among the Members, make
     appropriate revisions to the Plan of Merger and submit such revised plan to
     the Members for their approval. The provisions of Section 3.1(b) regarding
     allocation shall be amended to incorporate such revised allocations.

any obligation under, or constitute a default under, any mortgage, lien, lease,
agreement, instrument, order, arbitration award, judgment or decree to which
Medtrust is a party, or to which Medtrust is, or the assets, properties or
business of Medtrust are, subject, which would have a material adverse effect on
Medtrust or any of its assets except as set forth on Schedule 4.4. The Board of
Directors of Medtrust has approved this Agreement, has authorized the execution
and delivery hereof and has directed that this Agreement be submitted to the
Members of Medtrust for adoption at a special meeting of such Members following

consummate the transactions contemplated hereby. Except for the approval of its
Members, Medtrust has taken all action required by law, its articles of
incorporation, its by-laws or otherwise to authorize and to approve the
execution and delivery of this Agreement and the documents, agreements and
certificates executed and delivered by Medtrust in connection herewith and the
consummation by Medtrust of the transactions contemplated hereby. This Agreement
has been duly executed and delivered by Medtrust and constitutes a valid and
legally binding obligation of Medtrust, enforceable against Medtrust in
accordance with its terms. No consent, action, approval or authorization of, or
registration, declaration or filing with, any governmental authority is required
to be obtained by Medtrust in order to authorize the execution and delivery by
Medtrust of this Agreement or the consummation by Medtrust of the Merger other
than the filings with the State Corporation Commission contemplated by this
Agreement.
     E. FINANCIAL STATEMENTS. Medtrust has furnished to DHS copies of the
financial statements compiled by its accountant for 1994 and 1995 (the "Medtrust
Financial Statements"). The Medtrust Financial Statements have been prepared in
accordance with generally accepted accounting principles ("GAAP") applied on a
consistent basis throughout the periods covered thereby, reflect and provide
adequate reserves in respect of all known liabilities of Medtrust in accordance
with GAAP, including all known contingent liabilities required to be included
therein, and present fairly the financial condition of Medtrust as of the
indicated dates and the results of operations of Medtrust for the indicated
periods.
     F. MATERIAL CONTRACTS AND AGREEMENTS. All material contracts of Medtrust
now in effect to which Medtrust is a party or by which it or its properties or
assets may be bound or affected are listed on Schedule 4.6. A true and complete
copy of each such material contract has been heretofore delivered to DHS (the
"Material Contracts"). No default, alleged default or anticipatory breach exists
on the part of Medtrust or, to the best knowledge of Medtrust, on the part of
any other party, under any Material Contract, and there are no material
agreements of the parties relating to any Material Contract that have not been
disclosed to DHS. Subject to receipt of the consents set forth on Schedule 4.6,
the consummation of the Merger will not give rise to a default under any such
Material Contract.
     G. TAX MATTERS.
          1. Medtrust has filed all tax returns required to be filed by it under
     the laws of the United States of America, the jurisdiction of its
     incorporation, and each state or other jurisdiction in which it conducts
     business activities and is required to file. Medtrust has paid or set up an
     adequate reserve in respect of all taxes for the periods covered by such
     returns. Medtrust does not have any tax liability for which no tax reserve
     has been made in respect of any jurisdiction in which Medtrust has business
     activities and is required to file.
          2. There are no tax liens, whether imposed by any federal, state or
     local taxing authority, outstanding against any of the assets, properties
     or business of Medtrust.
          3. All taxes and assessments that Medtrust is required to withhold or
     to collect have been duly withheld or collected and all withholdings and
     collections have either been duly and timely paid over to the appropriate
     governmental authority or are, together with the payments due or to become
     due in connection therewith, duly reflected on the Medtrust Financial
     Statements in accordance with GAAP.
                                      A-3
 
<PAGE>
          4. Except as set forth in Schedule 4.7, no Medtrust tax returns for
     tax years that are open under any applicable statute of limitations have
     been examined by the Internal Revenue Service or other tax authorities, and
     no deficiencies (including any penalties or interest) have been asserted or
     assessments made as a result of examinations. There are no waivers,
     agreements or other arrangements providing for extension of time with
     respect to the assessment or collection of any unpaid tax, interest, or
     penalties relating to Medtrust. No issues have been raised by (or are
     currently pending before) the Internal Revenue Service or any other taxing
     authority in connection with any of Medtrust's tax returns which could
     reasonably be expected to have a material adverse effect on the financial
     condition of Medtrust if decided adversely to Medtrust, nor are there any
     such issues which have not been so raised but if so raised by the Internal
     Revenue Service or any other taxing authority in connection with any of the
     Medtrust tax returns could, in the aggregate, reasonably be expected to
     have such material adverse effect.
     H. ABSENCE OF UNDISCLOSED LIABILITIES. Medtrust does not have any material
indebtedness, liability or obligation of any character whatsoever, whether or
not accrued and whether or not fixed or contingent, other than (i) liabilities
reflected in the Medtrust Financial Statements, (ii) liabilities incurred in the
ordinary course of business (or pursuant to the liquidation) of Medtrust since

previously been delivered to DHS are complete and correct. All such policies
will be outstanding and in full force and effect on the Closing Date and
thereafter in accordance with their terms. There are no claims, actions, suits
or proceedings arising out of or based upon any of such policies of insurance,
and, so far as is known to Medtrust or any of its officers, no basis for any
such claim, action, suit or proceeding exists. There are no notices of any
pending or threatened terminations with respect to any of such policies and
Medtrust is in compliance with all conditions contained therein.
     J. FINDERS OR BROKERS. Medtrust has not utilized the services of any

not limited to, governmental agencies of any kind) has any claim, or basis for
any action or proceeding, against Medtrust arising out of any statute, ordinance
or regulation relating to discrimination in employment or employment practices
or occupational safety and health standards (including, but without limiting the
foregoing, The Fair Labor Standards Act, as amended; Title VII of the Civil
Rights Act of 1964, as amended; 42 U.S.C. 1981 or the Age Discrimination in
Employment Act of 1967, as amended), which, if upheld, would have an adverse
effect on Medtrust or its condition, financial or otherwise. To the knowledge of
Medtrust, there is no pending or threatened federal or state equal employment
opportunity enforcement action or labor dispute, strike or work stoppage
affecting Medtrust. Medtrust does not have any collective bargaining or similar
agreements, nor does it have any obligation to bargain with any labor
organization as the representative of Medtrust's employees, and there is neither
pending, nor to Medtrust's knowledge threatened, any labor dispute, strike or
work stoppage with affects or which may affect Medtrust or which may interfere
with the continued operation of Medtrust. No present or former employee of
Medtrust has any claim against Medtrust for (i) overtime pay, other than
overtime pay for the current payroll period, (ii) wages, salary or other
compensation or benefits for any period other than the current payroll period,
(iii) except as set forth in Medtrust's Financial Statements, vacation, time off

regulation relating to minimum wages or maximum hours of work.
                                      A-4
 
<PAGE>
     M. COMPLIANCE WITH LAWS. Medtrust is not in violation of any order, writ,
decree or judgment of any court, arbitrator, or governmental or regulatory body
which violation would (i) affect the legality, validity or enforceability of
this Agreement or the transactions contemplated hereby, (ii) have a material
adverse effect on Medtrust's assets, or (iii) impair Medtrust's obligations to
perform fully on a timely basis any material obligations of Medtrust under this
Agreement.

     material to their respective businesses and which would continue past the
     Effective Time. Medtrust is not in default with respect to any order, writ,
     injunction or decree known to or served upon Medtrust of any court or of
     any governmental authority.

     G. LITIGATION.
          1. Except as set forth on Schedule 5.7, there is no (i) action, suit,
     claim, proceeding or investigation pending or, to the knowledge of DHS or
     any officer of DHS, threatened against or affecting DHS or its assets,
     employees or properties, at law or in equity, or before or by any court or

     qualification of DHS to hold or receive any permit) and DHS does not know
     of any basis for any of the foregoing. There are no pending actions, suits,
     claims or proceedings brought by DHS against others.
          2. DHS has not received any written opinion, memorandum, legal advice
     or notice from legal counsel to the effect that they are exposed, from a
     legal standpoint, to any liability or disadvantage which may be material to
     their respective businesses and which would continue past the Effective
     Time. DHS is not in default with respect to any order, writ, injunction or
     decree known to or served upon DHS of any court or of any governmental
     authority.
          3. DHS knows of no pending or threatened action, suit, proceeding,
     investigation, order or injunction before or by any court or governmental
     body that seeks to restrain or to prevent the consummation of the Merger or
     the other transactions contemplated by this Agreement.
     H. MATERIAL CONTRACTS AND AGREEMENT. No default, alleged default or
anticipatory breach exists on the part of DHS or, to the best knowledge of DHS
or any of its officers, on the part of any other party, under any material
agreement, written or oral, relating to the business of DHS.
     I. TAX MATTERS.
          1. DHS has filed all tax returns required to be filed by it under the
     laws of the United States of America, the jurisdiction of its
     incorporation, and each state or other jurisdiction in which it conducts
     business activities and is required to file. DHS has paid or set up an
     adequate reserve in respect of all taxes for the periods covered by such
     returns. DHS does not have any tax liability for which no tax reserve has

                                      A-6
 
<PAGE>
     which DHS has business activities and is required to file. DHS has set up
     as provisions for taxes on the DHS Balance Sheet amounts sufficient for all
     accrued and unpaid federal, state, county and local taxes of DHS, whether
     or not disputed, including any interest and penalties in connection
     therewith, for all fiscal periods ending on or before the date of the DHS
     Balance Sheet.
          2. No examinations of DHS' federal income tax returns are in progress.
     The results of any settlements and any necessary adjustments in state
     income tax resulting therefrom are properly reflected in DHS' financial
     statements referred to in Section 5.5. DHS is not aware of any fact which
     would constitute grounds for any further tax liability with respect to the
     years which have not been examined. No agreements or waivers have been made
     by or on behalf of DHS for the extension of time for the assessment of any
     tax or for any applicable statute of limitations.
          3. Except for taxes for the payment of which an adequate reserve has
     been established on the DHS Balance Sheet, there are no tax liens, whether
     imposed by any federal, state or local taxing authority, outstanding
     against any of the assets, properties or business of DHS.
          4. All taxes and assessments that DHS is required to withhold or to
     collect have been duly withheld or collected and all withholdings and
     collections have either been duly and timely paid over to the appropriate
     governmental authority or are, together with the payments due or to become
     due in connection therewith, duly reflected on the DHS Balance Sheet in
     accordance with GAAP.
     J. ABSENCE OF UNDISCLOSED LIABILITIES. DHS does not have any material
indebtedness, liability or obligation of any character whatsoever, whether or
not accrued and whether or not fixed or contingent, other than (i) liabilities

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth below, and other good and valuable consideration the receipt and
sufficiency of which are acknowledged, the parties, intending to be legally
bound, covenant and agree as follows:
     1. RECITALS; DEFINITIONS.
     (A) RECITALS. The foregoing recitals are made a part of this Agreement.
     (B) CERTAIN DEFINITIONS.
                                      B-1
 
<PAGE>
     "CHANGE IN CONTROL" shall mean the earlier to occur of the following: (i) a
liquidating distribution to DHS' stockholders (or similar event); (ii) a
contribution, consolidation or merger where DHS is not the survivor; (iii) any
sale, exchange or other disposition of all, or substantially all, of DHS'
assets; or (iv) any public offering of DHS' securities at a company value of at
least $25,000,000 with proceeds to DHS of at least $15,000,000.
     "DHS AMENDED AND RESTATED ARTICLES" shall mean the Articles of Amendment
and Restatement of DHS filed with the Maryland State Department of Assessments
and Taxation and effective on September 4, 1996
     (C) OTHER DEFINED TERMS. When used in this Agreement with its initial
letter capitalized, a word that is not defined in this Section 1 shall have the
meaning set forth elsewhere in this Agreement. When a word used in this
Agreement with its initial letter capitalized is not defined in this Agreement,
such word shall have the meaning set forth in the Definition Appendix attached
to this Agreement as Appendix A.
     2. STOCK, WARRANTS AND OPTIONS COVERED; ADDITIONAL PARTIES. Except as
otherwise provided herein, all of the provisions of this Agreement shall apply
to, and the term "Stock" shall include, the Stock and all other shares of
capital stock and rights, including warrants and options, to acquire shares of
capital stock and all other equity securities now owned or which may be issued
hereafter to the Stockholders in consequence of any additional issuance,
purchase, exchange or reclassification of shares, corporate reorganization, or
any other form of recapitalization, consolidation, merger, share split, share
dividend, or which are acquired by Stockholders in any other manner. For
purposes of this Agreement, the term "Stock" shall include (i) beneficial
interests held by any beneficiary in any trust permitted to be a transferee
hereunder, (ii) that certain Stock Warrant No. 1 executed and delivered on
November 28, 1995 by DHS to the Series B Investor granting to the Series B
Investor the right to acquire Eighty Eight Thousand Eight Hundred Eighty Nine
(88,889) shares of the Class A Common Stock of the Company (the "WARRANT"), and
(iii) the option of the Series C Investor to purchase Five Hundred Thousand
(500,000) shares of Series C Preferred Stock from DHS pursuant to the Option
Agreement dated as of September 4, 1996 between DHS and the Series C Investor
(the "OPTION"). The parties hereto acknowledge and agree that upon conversion of
shares of Convertible Preferred Stock into shares of Class C Common Stock all
references to "Stock" and all references to "Convertible Preferred Stock" herein
shall include all such shares of Class C Common Stock, and all references to
"holders of Convertible Preferred Stock" shall include "holders of Class C
Common Stock." DHS acknowledges and agrees that it will not issue any additional
shares of its capital stock (or options) to any person or entity which is not a
party to this Agreement without requiring, as a condition precedent to such
issuance, that such person or entity execute a counterpart to this Agreement
(provided that non-executive employees of DHS to whom shares of capital stock
are issued pursuant to any employment agreement or any stock option, stock
purchase or similar plan of DHS shall not be required to execute this Agreement
so long as DHS, as a condition of such issuance, retains rights to repurchase
such shares of capital stock under substantive terms and conditions consistent
with those granted to DHS herein), and any member of DHS' executive management
team who is granted shares (or options) shall be deemed a "Management
Stockholder" for purposes hereof.
     3. PURCHASE AND SALE. DHS agrees to purchase and redeem, and each
Stockholder agrees to sell and transfer, the Stock in the manner and upon the
terms provided in this Agreement. No purchase, sale, gift, endorsement,
assignment, transfer, pledge, encumbrance or other disposition, whether
voluntary, involuntary or by operation of law, including, without limitation,
any transfer pursuant to a divorce decree, of any shares of Stock of any
Stockholder shall be valid and binding except as provided in, and in accordance
with, the terms and conditions of this Agreement. Any purported transfer by any
Stockholder of the Stock or issuance of capital stock by the Company other than
in accordance with this Agreement shall be null and void, and DHS shall refuse
to recognize any such transfer and shall not reflect on its records any change
in record ownership of the Stock pursuant to any such transfer. Any transferee
of the Stock becoming the owner of the Stock in compliance with this Agreement
shall thereafter be deemed a Stockholder. The personal representative of a
deceased Stockholder shall automatically be subject to the terms and conditions
of this Agreement. Notwithstanding the foregoing, the holders of Convertible
Preferred Stock are entitled, pursuant to the terms of the DHS Amended and
Restated Articles, to exercise rights to convert shares of Convertible Preferred
Stock into shares of Class C Common Stock, and to require DHS to purchase shares
of Convertible Preferred Stock under certain circumstances, and no such
conversion or redemption shall give any person any rights under this Agreement.
     4. DEATH, DISABILITY AND TERMINATION OF EMPLOYMENT OF A MANAGEMENT
STOCKHOLDER; INVOLUNTARY TRANSFERS.
     (A) GENERAL.
          (i) Upon the occurrence of the termination of employment of any
     Management Stockholder (except with respect to each of Rifkin and Kimmel,
     the termination of whose employment is governed by Section 4(f) hereof)
     with DHS for any reason, other than an "Involuntary Transfer" (as defined
     below) including, but not limited to, death or "disability" (as
                                      B-2
 
<PAGE>
     defined in Section 4(c) below), such Management Stockholder or other
     Stockholder, as the case may be, shall sell, and DHS shall purchase, all of
     the Stock then registered in such Stockholder's name at the price provided
     in Section 4(e) or Section 6 hereof, as the case may be, and upon the terms
     provided in Section 7 hereof.
          (ii) Upon the occurrence of an "Involuntary Transfer" (as defined in
     Section 4(d) below) of the Stock of any Stockholder (the "INVOLUNTARY
     TRANSFER STOCKHOLDER"), DHS shall have the right, for a period of thirty
     (30) days from the date of such occurrence, to purchase such Stock by
     providing written notice to such effect to such Involuntary Transfer
     Stockholder and to any court which has then exercised jurisdiction over
     such Involuntary Transfer Stockholder with respect to its Stock, or to any
     assignee, trustee in bankruptcy or successor in interest, as the case may
     be, and such Involuntary Transfer Stockholder shall be obligated if DHS
     elects to exercise its right to purchase such Stock to sell all but not
     less than all of the Stock then registered in such Involuntary Transfer
     Stockholder's name at the price provided in Section 6 hereof and upon the
     terms provided in Section 7 hereof. If DHS elects not to exercise its
     purchase pursuant to this Section 4(a) (ii) within such thirty (30) day
     period, it shall immediately provide written notice to that effect to all
     of the other stockholders (the "NON-INVOLUNTARY TRANSFER STOCKHOLDERS"),
     who shall have the option to purchase, and such Involuntary Transfer
     Stockholder shall be obligated to sell to the extent such option is
     exercised, all of the shares of such Stock at the price provided in Section
     6 hereof and upon the terms provided in Section 7 hereof. If more than one
     Non-Involuntary Transfer Stockholder desires to so purchase, then they
     shall purchase in such proportions as they may agree. In the absence of
     agreement, each of the Non-Involuntary Transfer Stockholders desiring to
     purchase such stock shall be entitled to purchase up to that number of
     shares of such Stock which is equal to the product of his percentage
     interest of all of the shares of DHS Capital Stock then held by such
     Non-Involuntary Transfer Stockholders multiplied by the number of shares of
     stock available for purchase hereunder. The Non-Involuntary Transfer
     Stockholders shall have the right to exercise their respective options for
     a period of thirty (30) days following their receipt of DHS' notice that it
     has elected not to purchase such Stock by providing notice in the manner
     required of DHS as otherwise set forth in this Section 4(a)(ii).
     (B) FURTHER ASSURANCES. Each Management Stockholder hereby agrees that he
and/or his personal representative, and each trustee of any permitted trust
hereunder, shall be bound to take any and all action necessary to enable DHS to
purchase his Stock pursuant to the provisions of this Section 4.
     (C) DISABILITY. For purposes of this Section 4, "DISABILITY" with respect
to a Management Stockholder shall have the meaning set forth in said Management
Stockholder's DHS Employment Agreement or other employment agreement with DHS,
and if no such agreement exists, as determined by DHS' Board of Directors in the
exercise of its reasonable discretion.
     (D) INVOLUNTARY TRANSFERS; PAYMENT. For purposes of this Section 4, the
occurrence of any of the following events shall constitute an "INVOLUNTARY
TRANSFER": (i) if any portion of a Stockholder's Stock is attached or taken in
execution, or (ii) if a Stockholder applies for the benefit of, or files a case
under, any provision of the federal bankruptcy law or any other law relating to
insolvency or relief of debtors, or (iii) if a case or proceeding is brought
against a Stockholder under any provision of the federal bankruptcy law or any
other law relating to insolvency or relief of debtors which is not dismissed
within sixty (60) days after the commencement thereof, or (iv) if a Stockholder
makes an assignment for the benefit of creditors, or (v) if any portion of a
Stockholder's Stock is made subject to a charging order, or (vi) if any portion
of a Management Stockholder's Stock or other Stock held by a natural person is
transferred pursuant to a divorce decree. For purposes of this Section 4(d), the
occurrence of any of the foregoing events described in Sections 4(d) (i) through
(v) above, (A) with respect to the General Partner of the LP, shall constitute
an Involuntary Transfer with respect to the LP of the Class B Common Stock, (B)
with respect to the Series A Investor, shall constitute an Involuntary Transfer
of the Series A Preferred Stock or the Class C Common Stock, as the case may be,

Transfer of the Series B Preferred Stock, the Warrant or the Class C Common
Stock, as the case may be, and (D) with respect to the Series C Investor, shall
constitute an Involuntary Transfer of the Series C Preferred Stock, the Option
or the Class C Common Stock, as the case may be. If any Stockholder has actual
knowledge of an Involuntary Transfer by a Stockholder of his or its Stock, such
Stockholder shall give written notice to such effect to DHS, and the giving of
such written notice shall constitute the occurrence of such event for purpose of
the time period set forth in this Section 4(d).
     (E) PAYMENT UPON TERMINATION OF EMPLOYMENT OF MANAGEMENT STOCKHOLDER OTHER
THAN RIFKIN OR KIMMEL. If the employment of a Management Stockholder other than
Rifkin or Kimmel with DHS is terminated, then the Management Stockholders whose
employment with DHS has not been terminated shall have the option, for a period
of sixty (60) days from the date of such termination, to purchase (in such
proportions as they shall agree upon or, if they cannot agree, in proportion to
their ownership of DHS Class A Common Stock other than the stock of the
terminated Management Stockholder) and, if such option is accepted, such
terminated Management Stockholder shall sell all of the shares of Stock held by

terms substantially identical to those set forth in Section 7 hereof (other than
subsections (c) and (d) thereof) and for a price determined in accordance with
Subsections (i) and (ii) of this Section 4(e). If all of the Terminated
Manager's Stock is not purchased by the other Management Stockholders, DHS shall
purchase, within ninety (90) days after the date of said termination, and such
terminated Management Stockholder shall sell, all of the Terminated Manager's
Stock upon the following terms and at the following prices:
          (i) if such Management Stockholder's employment is terminated (A) by
     DHS for any of the specific reasons enumerated in Section 4.3(a) of such
     Management Stockholder's DHS Employment Agreement, or, if no such agreement
     is then in effect, for "good cause" under applicable law, or (B) by the
     Management Stockholder for any reason not constituting "constructive
     termination" as defined in Section 4.4(b) of such Management Stockholder's
     DHS Employment Agreement, then at a price equal to the lower of such
     Management Stockholder's acquisition cost for his Stock or One Dollar
     ($1.00) per share, and upon the terms set forth in Section 7 hereof; or
          (ii) if such Management Stockholder's employment is terminated (A) by
     death, or by "disability" (as defined herein), or (B) by expiration of the
     term of such DHS Employment Agreement, or (C) by DHS without good cause as
     contemplated by Section 4.3(b) of such Employment Agreement, or (D) by the
     Management Stockholder for reasons constituting "constructive termination"
     under such Agreement, then at the price set forth in Section 6 hereof, and
     upon the terms set forth in Section 7 hereof.
If DHS is required, pursuant to the provisions of this Section 4(e), to purchase
the Terminated Manager's Stock at a price determined pursuant to Subsection (ii)
hereof, DHS shall, as a condition precedent to the closing of such purchase, on
or before the Closing Date for its acquisition of the Terminated Manager's
Stock, pay to (A) the Series A Investor all of the dividends then accrued but
unpaid on the Series A Preferred Stock plus all accrued and unpaid interest
thereon (whether by payment of cash or set off of any accrued but unpaid

Offering on or before August 30, 1998 as defined in the Articles of Amendment
and Restatement dated September 4, 1996, then on or before the consummation of a
Qualified Public Offering on or before August 30, 1998 (at a price per share not
less than the weighted average price paid or to be paid by the Series C Investor
for all shares of Series C Preferred Stock then oustanding) the Series C
Investor shall pay DHS an amount equal to the amount of dividends and interest
paid to the Series C Investor pursuant to this Section.
     (F) TERMINATION OF EMPLOYMENT, DEATH, DISABILITY OF RIFKIN AND KIMMEL.
          (i) TERMINATION OF EMPLOYMENT WITHOUT GOOD CAUSE. Except as set forth
     in the proviso to this sentence, if the employment of Rifkin or Kimmel, as
     the case may be, with DHS is terminated (A) by DHS for any of the specific
     reasons enumerated in Section 4.3(a) of his respective DHS Employment
     Agreement (or, if no such agreement is then in effect, for "good cause"
     under applicable law), or (B) by Rifkin or Kimmel, as the case may be, for
     any reason not constituting "constructive termination" as defined in
     Section 4.4(b) of such DHS Employment Agreement, then Rifkin or Kimmel, as
     the case may be, shall sell, and DHS shall purchase, all of the stock then
     registered in Rifkin's or Kimmel's name, as the case may be, at a price
     equal to the lower of Rifkin's or Kimmel's, as the case may be, acquisition
     cost for his Stock or One Dollar ($1.00) per share, and upon the terms
     provided in Section 7 hereof; provided, however, that the provisions of
     this paragraph 4(f) (i) shall not apply to any shares of capital stock of
     DHS held by Rifkin or Kimmel on the date hereof (or received as a
     distribution on or in respect of such shares after the date hereof as the
     result of any recapitalization, stock split or similar event).
          (ii) DEATH; DISABILITY. Upon each of (A) the death of Rifkin or
     Kimmel, as the case may be, and the appointment and qualification of such
     deceased stockholder's personal representative, and (B) the "Disability" of
     Rifkin or Kimmel (as such term is defined in each such shareholder's
     current employment agreement with DHS or, if there is none, as reasonably
     determined by the Board of Directors of DHS), as the case may be, such
     personal representative, Rifkin or Kimmel, as the case may be, may, for a
     period of sixty (60) days from the date of such appointment and
     qualification or disability, as the case may be, offer to the other
     Management Stockholders the option to purchase (in such proportions as they
     shall agree upon or, if they cannot agree, in proportion to their ownership
     of the DHS Class A Common Stock), all
                                      B-4
 
<PAGE>
     of the shares of Stock held by such personal representative, Rifkin or
     Kimmel, as the case may be, on terms substantially identical to those set
     forth in Section 7 hereof (other than Subsections (c) and (d) thereof) and
     at a price determined in accordance with the terms of Section 6 hereof. If
     the option to purchase all of the shares of Stock so offered is not
     exercised or accepted within such sixty (60) day period, then such personal
     representative, Rifkin or Kimmel, as the case may be, shall be entitled to
     sell, by providing written notice to DHS, and DHS shall be required to
     purchase upon receipt of such notice, all or any portion of such shares of
     Stock held by Rifkin or Kimmel, as the case may be, as such number of
     shares is set forth in such written notice, at the price and upon the terms
     provided in Sections 6 and 7 hereof.
          (iii) TERMINATION OF EMPLOYMENT UNDER OTHER CIRCUMSTANCES. If Rifkin's
     or Kimmel's employment is terminated (A) by expiration of the term of his
     respective DHS Employment Agreement, or (B) by DHS without good cause as
     contemplated by Section 4.3(b) of such Employment Agreements, or (C) by
     Rifkin or Kimmel, as the case may be, for reasons constituting
     "constructive termination" under such Agreements, then DHS shall purchase,
     within ninety (90) days after the date of such termination, and Rifkin and
     Kimmel shall sell, as the case may be, those shares (and only those shares)
     of capital stock of DHS acquired by Rifkin or Kimmel, as the case may be,
     after the date hereof (other than as a distribution on or in respect of
     shares held on the date hereof through a recapitalization, stock split, or
     similar event) at the price set forth in Section 6 hereof, and upon the
     terms set forth in Section 7 hereof.
If DHS is required, pursuant to the provisions of this Section 4(f), to purchase
the Terminated Manager's Stock at a price determined pursuant to Subsection (ii)
hereof, DHS shall, as a condition precedent to the closing of such purchase, on
or before the Closing Date for its acquisition of the Terminated Manager's
Stock, pay to (A) the Series A Investor all of the dividends then accrued but

and Restatement dated September 4, 1996, then on or before the consummation of a
Qualified Public Offering on or before August 30, 1998 (at a price per share not
less than the weighted average price paid or to be paid by the Series C Investor
for all shares of Series C Preferred Stock then oustanding) the Series C
Investor shall pay DHS an amount equal to the amount of dividends and interest
paid to the Series C Investor pursuant to this Section.
     (G) PRICE ADJUSTMENTS FOLLOWING A CHANGE IN CONTROL OF DHS. If the
employment of a Management Stockholder other than Rifkin or Kimmel with DHS is
terminated pursuant to the provisions in Section 4(e)(ii)(C) or (D) above, and
there occurs a Change in Control of DHS within the first twenty-four months
following the date of such termination, DHS agrees to pay or cause to be paid to
such terminated Management Stockholder (or to his heirs, legatees and/or
guardians), in addition to the purchase price for such terminated Management
Stockholder's Stock as determined pursuant to Section 7 hereof, the value of
such terminated Management Stockholder's fair, allocative, share of any
consideration that would have been payable to such terminated Management
Stockholder (less any such consideration actually received by such Management
Stockholder as a result of a sale of his Stock, whether to another Management
Stockholder, DHS or another person) or to DHS upon, and as a result of, such a
Change in Control of DHS within such twenty-four month period. Such payment
shall be made by DHS when and as DHS or the other DHS Stockholders receive
consideration as a result of such a Change in Control, and shall be paid by DHS
based upon such terminated Management Stockholder's pro-rata equity interest in
DHS at the time of termination. Any payment by DHS pursuant to this Section 4(f)
may, at DHS' option, be made by delivery of (i) cash, (ii) a promissory note
with a term of not more than ten years and interest at a rate calculated
pursuant to Section 1274(d) of the Internal Revenue Code of 1986, or (iii) an
appropriate in-kind distribution of any consideration received as a result of
such Change in Control. The parties hereto acknowledge and agree that each
Partner of the LP who has entered into a Professional Service Employment
Agreement with the LLC shall be entitled to receive, and pursuant to Section
7.3.3 (i) of the Limited Partnership Agreement has received, the benefit of the
substantive provisions set forth in this Section 4(g), upon the sale of his
Limited Partner Interest in the LP due to the termination of his employment with
BMG resulting from a termination by the LLC without good cause or a
"constructive termination," as defined therein.
     5. VOLUNTARY TRANSFERS OF STOCK.
                                      B-5
 
<PAGE>
     (A) STOCK RESTRICTED. Subject to the rights of the holders of Convertible
Preferred Stock set forth in the DHS Amended and Restated Articles, each
Stockholder agrees that, during his lifetime or its corporate existence or
otherwise, he or it will not sell, transfer, exchange, assign or otherwise
dispose of (by sale, gift, or otherwise), or mortgage, hypothecate, lien,
pledge, encumber or otherwise cause a security interest to be created in any of
his or its Stock, except upon satisfaction of the conditions set forth in this
Section 5 and Section 4 above. Notwithstanding the foregoing, (i) each
Management Stockholder shall be entitled to transfer all or any portion of his
shares of Stock to a trust solely for the benefit of himself, his spouse and/or
his lineal descendants provided that, as a condition of said transfer, (A) the
agreement governing said trust requires transfers of any beneficial interests
therein (other than among such permitted persons) to be treated as transfers of
Stock hereunder and subject to the terms hereof, and (B) all trustees of said
trust execute and deliver to the parties hereto a counterpart of this Agreement
and otherwise agree to be bound by all of the terms and provisions hereof with
respect to the Stock, and (ii) each holder of Convertible Preferred Stock and of
Class B Common Stock may transfer its Convertible Preferred Stock or Class B
Common Stock, as the case may be, to any entity all of the ownership interests
in which are owned by such holder, provided that such transferee executes and
delivers to the parties hereto a counterpart of this Agreement and otherwise
agrees to be bound by all of the terms and provisions hereof.
     (B) DELEGATION RIGHTS. If DHS is unable to exercise any of its purchase
rights hereunder, it shall be entitled to delegate such rights to such of the
Stockholders who desire to purchase stock upon the occurrence of the events set
forth in Sections 4(a)(i) or (ii) hereof, provided such stockholders, as a
condition of such obligation, shall be entitled to purchase such stock pro rata
as consolidated pursuant to Section 4(a)(ii) hereof.
     (C) VOLUNTARY TRANSFERS BY MANAGEMENT STOCKHOLDERS.
          (i) OPTION OF OTHER MANAGEMENT STOCKHOLDERS. A Management Stockholder
     shall have the right to receive a bona fide offer to purchase (which he is
     willing to accept) (a "MANAGEMENT OFFER") from any independent third person
     capable of consummating such a sale of all, but not less than all, of his
     Stock (the "Management Offered Stock"). Before accepting a Management
     Offer, such Management Stockholder shall first offer in writing (the
     "MANAGEMENT STOCKHOLDER'S OFFER") to sell the Management Offered Stock to
     the other Management Stockholders (the "OTHER MANAGEMENT STOCKHOLDERS") at
     the price and on the terms on which such selling Management Stockholder
     proposes to transfer the Management Offered Stock to the proposed third
     party transferee. The Management Stockholder's Offer shall set forth (A)
     the number of shares of the Management Offered Stock, (B) the name and
     address of the proposed transferee, (C) the amount of consideration to be
     received by the selling Stockholder, and (D) the method of proposed
     payment. A copy of the Management Stockholder's Offer shall simultaneously
     also be sent to all of the other Stockholders and to DHS.
          The Other Management Stockholders shall have the option to acquire all
     or any of the shares of Management Offered Stock at the price and upon the
     terms provided in the Management Stockholder's Offer. If more than one
     Other Management Stockholder desires to purchase the Management Offered
     Stock, such Management Offered Stock shall be purchased by them in such
     proportions as they may agree. In the absence of agreement, each of the
     Other Management Stockholders desiring to purchase the Management Offered
     Stock shall be entitled to purchase up to that number of shares of
     Management Offered Stock which is equal to the product of such number of
     shares of Management Offered Stock divided by the number of other
     Management Stockholders desiring to purchase such shares of Stock. The
     Other Management Stockholders shall have the right to exercise their
     respective options to purchase the Management Offered Stock, for a period
     of thirty (30) days following their receipt of the Management Stockholder's
     Offer, by notifying the selling Management Stockholder in writing of their
     respective intentions to purchase at Closing (as defined in Section 7(e)
     hereof) all or any shares of the Management Offered Stock.
          (ii) OPTION OF THE HOLDERS OF CLASS B COMMON STOCK. If the Other
     Management Stockholders do not accept the Management Stockholder's Offer to
     purchase all of the shares of Management Offered Stock within the period of
     thirty (30) days provided in Section 5(c)(i), then the selling Management
     Stockholder, immediately thereafter, shall be deemed to have made an offer
     (the "MANAGEMENT STOCKHOLDER'S SECOND OFFER") to sell all of the remaining
     shares of the Management Offered Stock (the "REMAINING MANAGEMENT OFFERED
     STOCK") to the holders of Class B Common Stock at the price and upon the
     terms provided in the Management Stockholder's Offer. The holders of the
     Class B Common Stock shall have the option, for a period of fifteen (15)
     days after the earlier to occur of (A) expiration of the thirty (30) day
     period provided in Section 5(c)(i), or (B) notification by all of the Other
     Management Stockholders to the holders of Class B Common Stock to the
     effect that the Other Management Stockholders, in the aggregate, have
     elected to purchase less than all of the shares of Management Offered Stock
     as provided in Section 5(c)(i), to purchase all of the Remaining Management
     Offered Stock, upon written notification to the selling Management
     Stockholder, at the price
                                      B-6
 
<PAGE>
     and upon the terms provided in this Section 5(c). If more than one holder
     of Class B Common Stock desires to purchase the Remaining Management
     Offered Stock, such Remaining Management Offered Stock shall be purchased
     by them in such proportions as they may agree. In the absence of agreement,
     each of the holders of Class B Common Stock desiring to purchase the
     Remaining Management Offered Stock shall be entitled to purchase up to that
     number of shares of Remaining Management Offered Stock which is equal to
     the product of his percentage interest of all of the shares of Class B
     Common Stock held by all such holders of Class B Common Stock times the
     number of shares of Remaining Management Offered Stock available for
     purchase hereunder. The holders of Class B Common Stock shall have the
     right to exercise their respective options to purchase the Remaining
     Management Offered Stock by notifying the selling Management Stockholder in
     writing of their respective intentions to purchase at Closing (as defined
     in Section 7(e) hereof) all or any shares of the Remaining Management
     Offered Stock.
          (iii) OPTION OF THE HOLDERS OF CONVERTIBLE PREFERRED STOCK. If the
     holders of Class B Common Stock do not accept the Management Stockholder's
     Second Offer to purchase all of the shares of Remaining Management Offered
     Stock within the period of fifteen (15) days provided in Section 5(c)(ii),
     then the selling Management Stockholder, immediately thereafter, shall be
     deemed to have made an offer (the "MANAGEMENT STOCKHOLDER'S THIRD OFFER")
     to sell all of the remaining shares of the Remaining Management Offered
     Stock (the "AVAILABLE MANAGEMENT OFFERED STOCK") to the holders of
     Convertible Preferred Stock at the price and upon the terms provided in the
     Management Stockholder's Offer. The holders of Convertible Preferred Stock
     shall have the option, for a period of fifteen (15) days after the earlier
     to occur of (A) expiration of the fifteen (15) day period provided in
     Section 5(c)(ii), or (B) notification by all of the holders of Class B
     Common Stock to the holders of Convertible Preferred Stock to the effect
     that the holders of Class B Common Stock have elected to purchase less than
     all of the shares of Remaining Management Offered Stock as provided in
     Section 5(c)(ii), to purchase all of the Available Management Offered
     Stock, upon written notification to the selling Management Stockholder, at
     the price and upon the terms provided in this Section 5(c). If more than
     one holder of Convertible Preferred Stock desires to purchase the Available
     Management Offered Stock, such Available Management Offered Stock shall be
     purchased by them in such proportions as they may agree. In the absence of
     agreement, each of the holders of Convertible Preferred Stock desiring to
     purchase the Available Management Offered Stock shall be entitled to
     purchase up to that number of shares of Available Management Offered Stock
     which is equal to the product of his percentage interest of all of the
     shares of Convertible Preferred Stock held by all such holders of
     Convertible Preferred Stock times the number of shares of Available
     Management Offered Stock available for purchase hereunder. The holders of
     Convertible Preferred Stock shall have the right to exercise their
     respective options to purchase the Available Management Offered Stock by
     notifying the selling Management Stockholder in writing of their respective
     intentions to purchase at Closing (as defined in Section 7(e) hereof) all
     or any shares of the Available Management Offered Stock.
          (iv) OPTION OF DHS. If the holders of Convertible Preferred Stock do
     not accept the Management Stockholder's Third Offer to purchase all of the
     shares of Available Management Offered Stock within the period of fifteen
     (15) days provided above in Section 5(c)(iii), then the selling Management
     Stockholder, immediately thereafter, shall be deemed to have made an offer
     (the "FINAL MANAGEMENT STOCKHOLDER'S OFFER") to sell all of the remaining
     shares of the Available Management Offered Stock (the "FINAL MANAGEMENT
     OFFERED STOCK") to DHS at the price and upon the terms provided in the
     Management Stockholder's Offer. DHS shall have the option, for a period of
     fifteen (15) days after the earlier to occur of (i) expiration of the
     fifteen (15) day period provided in Section 5(c)(iii), or (ii) notification
     by all of the holders of Convertible Preferred Stock to DHS to the effect

     provided in Section 5(c)(iii), to purchase all or some of the Final
     Management Offered Stock, upon written notification to the selling
     Management Stockholder, at the price and upon the terms provided in the
     Management Stockholder's Offer.
          (v) TRANSFERS TO THIRD PARTIES. If (A) a Management Stockholder elects
     to transfer all of his shares of Management Stock; (B) said Management
     Stockholder strictly complies with the provisions of Sections 5(c) (i)
     through 5(c) (iv) above; (C) the Remaining Management Stockholders, the
     holders of Class B Common Stock, the holders of Convertible Preferred Stock

     Management Offered Stock; and (D) the Management Stockholder who desires to
     transfer the Management Offered Stock complies with the terms of this

     sold by the selling Management Stockholder to the third party named in the
     Management Stockholder's Offer within a period of thirty (30) days after
     the expiration of the fifteen (15) day period provided in Section 5(c)(iv).
     Such remaining Management Offered Stock may be transferred to the third
     party named in the Management Stockholder's Offer; provided that (X) such
     shares are sold at the price and on the terms set forth in the

     Common Stockholder proposes to transfer the Class B Common Offered Stock to

     Common Offered Stock (the "REMAINING CLASS B COMMON OFFERED STOCK") to DHS
     at the price and upon the terms provided in the Class B Common
     Stockholder's Offer. DHS shall have the option, for a period of fifteen
     (15) days after the earlier to occur of (i) expiration of the thirty (30)
     day period provided in Section 5(d)(i), or (ii) notification by all of the
     Other Stockholders to DHS to the effect that the Other Stockholders have
     elected to purchase less than all of the shares of Class B Common Offered
     Stock as provided in Section 5(d)(i), to purchase all of the Remaining
     Class B Common Offered Stock, upon written notification to such holder of
     Class B Common Stock, at the price and upon the terms provided in the Class
     B Common Stockholder's Offer.
          (iii) TRANSFERS TO THIRD PARTIES. If (A) the holder of Class B Common
     Stock elects to transfer all of its shares of Class B Common Stock; (B) the
     holder of Class B Common Stock strictly complies with the provisions of
     Sections 5(d) (ii) and (iii); (C) the Other Stockholders and DHS elect to
     purchase, in the aggregate, less than all of the shares of Class B Common
     Offered Stock; and (D) the holder of Class B Common Stock complies with the
     terms of this Section 5(c)(iii), then all of the Class B Common Offered
     Stock may be sold by the holder of Class B Common Stock to the third party
     named in the Class B Common Stockholder's Offer within a period of fifteen
     (15) days after the expiration of the fifteen (15) day period provided in
     Section 5(d)(ii). Such Class B Common Offered Stock may be transferred to
     the third party named in the Class B Common Stockholder's Offer; provided
     that (X) such shares are sold at the price and on the terms set forth in
     the Class B Common Stockholder's Offer; (Y) the shares so transferred shall
     remain subject to all of the provisions of this Agreement; and (Z) the
     third party transferee shall execute an instrument acceptable to counsel
     for DHS, pursuant to which such third party becomes a party to this
     Agreement and agrees to be bound by all of the provisions and terms or
     conditions hereof.
     (E) VOLUNTARY TRANSFERS BY THE HOLDERS OF CONVERTIBLE PREFERRED STOCK.
Notwithstanding any other provision of this Agreement or any other agreement to
which DHS and either of the Series A Investor, the Series B Investor or the
Series C
                                      B-8
 
<PAGE>
Investor are parties, no shares of Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, as the case may be, may be voluntarily
transferred pursuant to this Section 5(e) or otherwise if, at the time of such
attempt to transfer, (1) the Series A Investor, the Series B Investor or the
Series C Investor, respectively, has not made full payment to DHS in cash for
all shares of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock, as the case may be, held by the Series A Investor, the Series B
Investor or the Series C Investor, respectively, including all amounts of
principal and interest under any note given in partial consideration for such
shares, or (2) any holder of Convertible Preferred Stock proposing to sell such
stock pursuant to this Section 5(e) holds, at the time of such attempt at
transfer, rights to purchase additional shares of Convertible Preferred Stock.
          (i) OPTION OF DHS. Except as otherwise herein provided, each holder of
     Convertible Preferred Stock shall have the right to receive a bona fide
     offer to purchase (which it is willing to accept) (a "CONVERTIBLE PREFERRED
     STOCK OFFER"), from any independent third person capable of consummating
     such a sale, any or all of its shares of Convertible Preferred Stock (the
     "PREFERRED OFFERED STOCK"). Before accepting a Convertible Preferred Stock
     Offer, the holder of Convertible Preferred Stock shall first offer in
     writing (the "CONVERTIBLE PREFERRED STOCKHOLDER'S OFFER") to sell the
     Preferred Offered Stock to DHS at the price and on the terms on which the
     holder of Convertible Preferred Stock proposes to transfer the Preferred
     Offered Stock to the proposed third party transferee. The Convertible
     Preferred Stockholder's Offer shall set forth (A) the number of shares of
     the Preferred Offered Stock, (B) the name and address of the proposed
     transferee, (C) the amount of consideration to be received by the holder of
     Convertible Preferred Stock, and (D) the method of proposed payment.
          DHS shall have the option to acquire all, but not less than all, of
     the shares of Preferred Offered Stock at the price and upon the terms
     provided in the Convertible Preferred Stockholder's Offer. DHS shall have
     the right to exercise its option to purchase the Preferred Offered Stock,
     for a period of thirty (30) days following its receipt of the Convertible
     Preferred Stockholder's Offer, by notifying all of the holders of
     Convertible Preferred Stock in writing of its intention to purchase at
     Closing (as defined in Section 7(e) hereof) all or any shares of the
     Preferred Offered Stock.
          (ii) OPTION OF THE HOLDERS OF CONVERTIBLE PREFERRED STOCK. If DHS does
     not accept the Convertible Preferred Stockholder's Offer to purchase all of
     the Shares of Preferred Offered Stock within the period of thirty (30) days
     provided in Section 5(e)(i), then the selling holder of Convertible
     Preferred Stock, immediately thereafter, shall be deemed to have made an
     offer (the "SECOND CONVERTIBLE PREFERRED STOCKHOLDER'S OFFER") to sell all
     of the remaining shares of the Preferred Offered Stock (the "REMAINING
     PREFERRED OFFERED STOCK") to the other holders of Convertible Preferred
     Stock at the price and upon the terms provided in the Convertible Preferred
     Stockholder's Offer. The other holders of Convertible Preferred Stock shall
     have the option, for a period of fifteen (15) days after the earlier to
     occur of (A) expiration of the thirty (30) day period provided in Section
     5(e)(ii), or (B) notification by DHS to the holders of Convertible
     Preferred Stock to the effect that DHS has elected to purchase less than
     all of the shares of Remaining Preferred Offered Stock as provided in
     Section 5(e)(ii), to purchase all of the Remaining Preferred Offered Stock
     upon written notification to the selling holder of Remaining Preferred
     Offered Stock, at the price and upon the terms provided in the Convertible
     Preferred Stockholder's Offer. If more than one holder of Convertible
     Preferred Stock desires to purchase the Remaining Preferred Offered Stock,
     such Remaining Preferred Offered Stock shall be purchased by them in such
     proportions as they may agree. In the absence of agreement, each of the
     holders of Convertible Preferred Stock desiring to purchase the Remaining
     Preferred Offered Stock shall be entitled to purchase up to that number of
     shares of Remaining Preferred Offered Stock which is equal to the product
     of his percentage interest of all of the shares of Convertible Preferred
     Stock held by all such holders of Convertible Preferred Stock times the
     number of shares of Remaining Preferred Offered Stock available for
     purchase hereunder. The holders of Convertible Preferred Stock shall have
     the right to exercise their respective options to purchase the Remaining
     Preferred Offered Stock by notifying the selling holder of Convertible
     Preferred Stock in writing of their respective intentions to purchase at
     Closing (as defined in Section 7(e) hereof) all or any shares of the
     Remaining Preferred Offered Stock.
          (iii) TRANSFERS TO THIRD PARTIES. If (A) the holder of Convertible
     Preferred Stock elects to transfer all of its shares of Convertible
     Preferred Stock; (B) the holder of Convertible Preferred Stock strictly
     complies with the provisions of Sections 5(e) (i) and (ii); (C) DHS does
     not exercise its right to purchase all, but not less than all, of the
     shares of Preferred Offered Stock and the holders of Convertible Preferred
     Stock elect to purchase, in the aggregate, less than all of the shares of
     the Remaining Preferred Offered Stock; and (D) the holder of Convertible
     Preferred Stock complies with the terms of this Section 5(e)(iii), then
     all, but not less than all, of the shares of the Remaining Preferred
     Offered Stock may be sold by the holder of Convertible Preferred Stock to
     the third party named in the Convertible Preferred Stockholder's Offer
     within a period of thirty (30) days after the expiration of the fifteen
     (15) day period provided in Section 5(e)(ii). Such Remaining Preferred
     Offered Stock may be transferred to the third party named in the
     Convertible
                                      B-9
 
<PAGE>
     Preferred Stockholder's Offer; provided that (X) such shares are sold at
     the price and on the terms set forth in the Convertible Preferred
     Stockholder's Offer; (Y) the shares so transferred shall remain subject to
     all of the provisions of this Agreement; and (Z) the third party transferee
     shall execute an instrument reasonably acceptable to counsel for DHS,
     pursuant to which such third party becomes a party to this Agreement and
     agrees to be bound by all of the provisions and terms or conditions hereof.
     (f) The closing for any purchase by a Stockholder or DHS of shares proposed
to be voluntarily transferred by a Stockholder pursuant to a bona fide third
party offer under this Section 5 shall be held at 10:00 a.m. at the principal
offices of DHS in Owings Mills, Maryland, on the date set forth for the closing
in the bona fide offer. In the event that no such date is set forth in the bona
fide offer, the closing shall be held at the principal offices of DHS in Owings
Mills, Maryland, at 10:00 a.m., not later than the 30th day after the last to
expire of the time periods for giving of notice provided for under this Section
5 and applicable to such proposed voluntary transfer.
     6. PURCHASE PRICE OF STOCK FOR PURPOSES OF INVOLUNTARY TRANSFERS AND
SECTIONS 4(E)(II) AND 4(F)(II).
     (A) AGREEMENT OF THE PARTIES. With respect to purchases governed by the
provisions of Section 4(d), Section 4(e) (ii) and Section 4(f) (ii) hereof, if
the purchaser of Stock hereunder, on the one hand, and the transferring
Stockholder, on the other hand, agree in writing as to the purchase price for
the Stock to be sold pursuant to Section 4(d), 4(e) (ii) or Section 4(f) (ii)
hereof, as the case may be, such agreed price shall be the purchase price for
such Stock. If no agreement on the purchase price of such Stock can be reached
within thirty (30) days from the date of the occurrence of the applicable event
under the provisions of Section 4(d), or 4(e) (ii) or, with respect to the
occurrence of an event governed by Section 4(f)(ii), within thirty (30) days
after the receipt of the notice required to be determined thereunder, as the
case may be (provided that, with respect to the death of a Management
Stockholder other than Rifkin or Kimmel, such thirty (30) day period shall
commence upon the appointment and qualification of such deceased Management
Stockholder's personal representative), then the purchase price of said Stock
shall be determined pursuant to Section 6(b) hereof.
     (B) APPRAISAL.
          (i) If the purchase price of Stock to be sold pursuant to Section
     4(d), 4(e) (ii) or 4(f) (ii) is not agreed upon as provided in Section 6(a)
     within the time period stated therein, then within fourteen (14) days
     thereafter an appraiser or appraisers shall be jointly selected by the
     transferring Stockholder, on the one hand, and DHS on the other hand, and
     such jointly selected appraiser or appraisers shall determine the "fair
     market value of the Stock," which determination shall be binding and
     conclusive upon all parties. For purposes of this Section 6(b), the "FAIR
     MARKET VALUE OF THE STOCK" shall be an amount equal to the "Fair Market
     Value Per Share" of the Class being sold and purchased hereunder,
     multiplied by the number of shares of Stock of said Class of the
     transferring Stockholder which are being sold and purchased hereunder.
     "FAIR MARKET VALUE PER SHARE" shall be an amount as of the Disposition Date
     as determined by appraisal using such methods as the appraisers appointed
     hereunder determine, in the exercise of their sole discretion, is
     appropriate pursuant to this Section 6(b), taking into account any
     liquidation preferences or other rights attendant to such class, any
     minority stockholder discount, majority stockholder premium or
     marketability or other discount or premium, as the case may be.
     "DISPOSITION DATE" shall be the last day of the calendar month immediately
     preceding the event giving rise to the purchase of the Stock under Section
     4 hereof.
          (ii) If the transferring Stockholder, on the one hand, and DHS on the
     other hand, do not agree upon the selection of an appraiser or appraisers,
     as provided in Section 6(b)(i), within the period therein stated, then,
     within seven (7) days after the expiration of the fourteen (14) day period
     provided for in Section 6(b) (i) hereof, the transferring Stockholder shall
     appoint an appraiser, and DHS shall appoint a second appraiser. The two (2)
     appraisers so appointed shall appoint a third appraiser within seven (7)
     days after both shall have been appointed. If either the transferring
     Stockholder or DHS shall fail to so appoint an appraiser, the appraiser
     duly appointed by the other shall serve as the sole appraiser and such
     appraiser shall determine the fair market value of the Stock and such
     determination shall be binding, final and conclusive on all parties. The
     said appraisers so appointed (or the sole appraiser if any party fails to
     select an appraiser as provided above), shall, within thirty (30) days
     after the last appointment thereof determine the fair market value of the
     Stock and the determination of such appraiser shall be determinative of the
     fair market value of the Stock for the purposes of this Agreement and shall
     be binding, final and conclusive on all parties. If the appraisers cannot
     agree on the fair market value of the Stock, within the time allotted, then
     such fair market value shall be the median of the two appraisals closest in
     value to each other.
          (iii) All expenses incurred in the appraisal process shall be borne
     and paid equally by the transferring Stockholder, and DHS.
                                      B-10

     7. PAYMENT OF PURCHASE PRICE. The payment of any purchase price for Stock
transferred pursuant to Section 4 hereof may be made on such terms as are agreed
upon by the parties but, absent such agreement shall be made as follows:
     (A) CASH PORTION. Subject to the terms of Section 7(d) hereof and, with
respect to any Involuntary Transfer, subject to such other terms and conditions
as may be required by any court which has then exercised jurisdiction over any
Involuntary Transfer Stockholder with respect to its Stock, or to any assignee,
trustee in bankruptcy or successor in interest, as the case may be, (i) in the
event of any transfer pursuant to Section 4 (other than as a result of the death
of a Management Stockholder), (A) where DHS is the purchaser, ten percent (10%)
of the total purchase price of the Stock shall be paid in cash by DHS on the
Closing Date, as defined in Section 7(e) hereof, and (B) where any party other
than DHS is the purchaser, the entire amount of the purchase price of the Stock
shall be paid by check by such purchaser(s) on the Closing Date, and (ii) in the
event of any transfer as a result of the death of a Management Stockholder, DHS
shall pay by check on the Closing Date the greater of (A) the proceeds of any
life insurance policy or policies (but not in excess of the purchase price to be
paid by DHS hereunder) owned by DHS on which the deceased Management Stockholder
is the named insured and DHS is the applicant, owner and beneficiary, and which
policy or policies were purchased for the purpose of using the proceeds thereof
to purchase the shares of Stock of the deceased Management Stockholder upon his
death (rather than to reimburse DHS for the loss of the services to be provided
to DHS by the deceased Management Stockholder), or (B) ten percent (10%) of the
total purchase price of the Stock held by such deceased Management Stockholder.
Notwithstanding the foregoing, if DHS is a purchaser hereunder but is unable,
under applicable law, to make all or any portion of any payment otherwise due
hereunder on the Closing Date, DHS shall pay such portion, if any, as applicable
law permits, and the balance of such payment shall be payable pursuant to the
provisions of Section 7(b) hereof.
     (B) PROMISSORY NOTE. The balance of the purchase price shall be represented
by a promissory note of DHS, payable in seven (7) equal annual installments of
principal and interest, the first of which shall be due and payable on the first
anniversary of delivery of such note. The note shall be substantially in the
form of the promissory note attached hereto and made a part hereof as EXHIBIT A,
and contain terms and conditions substantially similar to the terms and
conditions contained therein. Interest shall accrue on, and be payable with, the
unpaid balance of said note from the Closing Date at a rate equal to the
applicable federal rate for long-term debt instruments then existing on the date
of issuance under Code Section 1274(d)(1). As security for payment of the
amounts due under such promissory note, DHS shall pledge to the selling
Stockholder such shares of Stock being acquired until such time as all payments
due thereunder have been paid in full, provided that such selling Stockholder
shall not be entitled to exercise any voting or other rights with respect to
such shares of Stock so long as DHS is not in default of any payment due under
such note.
     (C) DEBT DUE FROM STOCKHOLDER. Any debt due by the transferring Stockholder
to DHS shall be payable according to its terms, as shall any debt due by DHS to
the transferring Stockholder; except, however, that, regardless of the terms of
any such debt due by the Stockholder to DHS, any cash payment due under Section
7(a) hereof, as well as any insurance proceeds payable under Section 8 hereof,
with respect to the purchase of the transferring Stockholder's Stock shall,
instead of being paid to the transferring Stockholder, be first applied to the
discharge of any such indebtedness, until all such indebtedness is fully
discharged. The provisions of this Section 7(c) shall also apply to any
purchases of Stock by DHS pursuant to Section 5 hereof.
     (D) INVOLUNTARY TRANSFERS. DHS shall settle with an assignee, trustee in
bankruptcy, attaching court or officer or successor in interest holding Stock
received in an Involuntary Transfer by taking any or all such Stock in execution
and paying to them the purchase price for each share of such Stock calculated
pursuant to Section 6, but not exceeding the Stockholder's indebtedness and
proper items of expense. The balance of the value of such Stock, if any, shall
be distributable to the Stockholder with such payments to be applied in the
order due in accordance with Section 7.
     (E) CLOSING. Closing on the sale of any shares of Stock sold pursuant to
Section 4 of this Agreement shall, unless otherwise agreed to in writing by the
purchaser(s) and the transferring Stockholder, or otherwise provided in this
Agreement, be held at the principal place of business of DHS (i) thirty (30)
days from (A) the date that the last applicable period for exercising an
unexercised option to purchase has lapsed, (B) the date an option to purchase is
accepted or exercised, or (C) with respect to a sale as the result of the
disability of Rifkin or Kimmel pursuant to Section 4(f)(ii), the date of
delivery of the notice required thereunder, or (C) the occurrence of any event
set forth in Section 4(a) (other than death of a Management Stockholder), or
(ii) with respect to the death of a Management Stockholder, ninety (90) days
after the appointment and qualification of a deceased Management Stockholder's
personal representative (collectively, the "CLOSING DATE"); provided that, if an
appraiser or appraisers are appointed to determine the purchase price pursuant
to Section 6, then the Closing shall take place on a date no later than thirty
(30) days from the receipt by the selling Stockholder and the purchaser of the
determination of the fair market value of the Stock if such Closing Date would
occur later than the Closing Date otherwise
                                      B-11
 
<PAGE>
determined pursuant to this Section 7(e). At the Closing, upon payment of the
purchase price (including delivery of the notes), the certificates representing
the Stock to be purchased and sold hereunder shall be delivered by the selling
Stockholder (or his personal or legal representatives, as the case may be) to
the purchaser(s), appropriately endorsed in blank for transfer. If the
certificates representing any shares of Stock to be so transferred have not been
surrendered by the selling Stockholder, all rights of the holder thereof with
respect to said Stock (including voting rights) nonetheless shall cease and
terminate.
     8. LIFE INSURANCE.
     (A) PURCHASE AND OWNERSHIP OF POLICIES. As soon as practicable following
the execution of this Agreement, DHS shall use its commercially reasonable best
efforts to purchase a life insurance policy on the life of each Management
Stockholder in such amounts, if any, as DHS' Board of Directors deems reasonable
and appropriate. DHS shall be the owner and beneficiary of each such policy, and
any proceeds received thereunder shall be held by DHS in trust for the purposes
of satisfying DHS' purchase obligations hereunder. Each Management Stockholder
agrees to cooperate with DHS in obtaining, and in keeping in full force and
effect, all such policies. Once a policy has been purchased, DHS shall maintain
all such insurance policies in full force and effect and shall not, without the
prior written consent of the respective Management Stockholder, cancel any such
policy or take or omit to take any action which might give rise to the
termination or cancellation thereof. DHS shall pay premiums on all insurance
policies as they become due. DHS may, when it deems appropriate, apply any
dividends declared and paid on such policies to the payment of premiums. No
party hereto shall have any obligations hereunder to the extent a Management
Stockholder is either uninsurable or may not be insured as herein contemplated
at upon commercially reasonable terms. Notwithstanding the foregoing, DHS may,
in lieu of or in addition to policies of insurance acquired, owned and
administered as set forth above, in the discretion of its Board of Directors,
provide as benefits to its employees, including Management Stockholders, such
other and additional policies of insurance or other insurance benefit plans on
such other or additional terms and conditions, including ownership of policies
of insurance in whole or in part by employees, including Management
Stockholders, as it deems reasonable and appropriate.
     (B) OPTION TO PURCHASE POLICIES. If a Management Stockholder transfers all
of his Stock during his lifetime pursuant to Sections 4 or 5, or if this
Agreement is terminated without being superseded by a similar agreement prior to
such Management Stockholder's death, such Management Stockholder, or any
designee of such Management Stockholder, shall have the right, during the sixty
(60) day period beginning with the date of transfer or termination of this
Agreement, to purchase any life insurance policy insuring his life owned by DHS
by paying DHS an amount equal to the cash surrender value of such policy
(determined after payment of all policy loans incurred to pay premiums due
thereunder and interest thereon) as of the date of purchase, plus the unearned
portion of any premiums which shall have been paid thereon.
     9. VOTING BY STOCKHOLDERS.
     (A) SALE OF STOCKHOLDER'S STOCK. If any vote, consent, determination or
other action is required or permitted to be made by the Stockholders and/or by
DHS pursuant to the terms of this Agreement in order to authorize and permit DHS
to exercise any of its rights hereunder, any Stockholder who would, upon
exercise of said rights by DHS, thereby become obligated to sell his Stock,
shall cast his vote and otherwise act, (i) as a Stockholder, by voting his stock
in the same manner as do the holders of a majority of shares of Stock other than
his own, and, (ii) as a director, by voting in the same manner as do a majority
of the directors other than himself. A Stockholder who becomes obligated to sell
his shares of Stock hereunder shall execute such instruments as may be necessary
or appropriate to effect any action required or permitted to be taken by the
Stockholders and the directors of DHS pursuant to the terms of this Agreement.
     (B) CLASS A DIRECTORS. Each of the present and future holders of Class A
Common Stock hereby agrees (i) to vote his shares of Stock to elect Stewart
Gold, Alan Kimmel, and Scott Rifkin, as three of DHS' Class A Common Stock
Directors for as long as their respective Employment Agreements with DHS are in
full force and effect, and (ii) if then serving as a Class A Common Stock
Director, to offer to resign as a director immediately upon termination of his
employment with DHS.
     (C) ISSUANCE OF ADDITIONAL SHARES OF STOCK. Subject to such rights of the
Series A Preferred Stock Directors pursuant to Article IV, Section B.1(c) of the
DHS Amended and Restated Articles, to such rights of the Series B Preferred
Stock Directors pursuant to Article IV, Section C.1(c) of the DHS Amended and
Restated Articles, to such rights of the Series C Preferred Stock Directors
pursuant to Article IV, Section D.1(c) of the DHS Amended and Restated Articles,
to such rights of the holders of Series A Preferred Stock pursuant to Article
IV, Section B.1(e) of the DHS Amended and Restated Articles, to such rights of
the holders of Series B Preferred Stock pursuant to Article IV, Section C.1(e)
of the DHS Amended and Restated Articles, and to such rights of the holders of
Series C Preferred Stock pursuant to Article IV, Section D.1(e) DHS
                                      B-12
 
<PAGE>
Amended and Restated Articles, to exercise their respective rights with respect
to the matters set forth therein, each Stockholder agrees (i) to vote his or its
shares of Stock, (ii) to use commercially reasonable best efforts to cause his
or its Affiliates to vote their shares of Stock, and (iii) if serving as a
Director of DHS, to vote as a Director, to cause DHS to issue additional shares
of stock to the Persons and in the amounts as are necessary:
          (1) to comply with the provisions of a public offering of DHS Common
     Stock pursuant to a registration statement filed with the Securities and
     Exchange Commission;
          (2) to fund or comply with the provisions of a stock option plan,
     restricted option plan, employee stock purchase plan, stock bonus plan or
     other employee stock plan or benefit approved and implemented by the Board
     for the benefit of officers, directors or employees of DHS, provided that
     the aggregate numbers of shares issued in respect of all such plans shall
     not exceed ten percent (10%) of the fully diluted capital stock of DHS
     calculated as of the time of the issuance and after giving effect thereto;
          (3) upon conversion of any shares of Convertible Preferred Stock;
          (4) for the acquisition of another corporation by DHS by merger,
     purchase of substantially all of the assets of such corporation or other
     reorganization resulting in the ownership by DHS of not less than fifty
     percent (50%) of the voting power of such corporation;
          (5) as a result of a stock split, stock dividend or reclassification
     of shares of Common Stock distributable on a pro rata basis to all holders
     of Common Stock, with respect to any shares of Stock which have been
     repurchased by DHS and are being resold; and/or
          (6) to permit BMGGP, Inc., as General Partner of the LP, to issue
     Additional Limited Partner Interests upon acquisition of additional Medical
     Practices from and after the time that there are sixty-six (66) physicians
     who hold Limited Partner Interests in the LP (including options to purchase
     Limited Partner Interests) directly or indirectly through their
     professional corporations.
     10. SPECIFIC PERFORMANCE. Because the shares of Stock cannot be readily
purchased or sold in the open market, irreparable damage would result in the
event this Agreement is not specifically enforced. Therefore, the rights to, or
obligations of, any party shall be enforceable in a court by a decree of
specific performance, and appropriate injunctive relief may be applied for and
granted in connection therewith. Such remedies, and all other remedies provided
for in this Agreement, shall, however, be cumulative and not exclusive and shall
be in addition to any other remedies which any party may have under this
Agreement or otherwise. Notwithstanding any other provision of this Agreement,
including, without limitation, the provisions of this Section 9, holders of
Convertible Preferred Stock shall have no obligation to vote for any matter
which requires the consent of such Stockholders or of the directors of DHS
elected by them under the Amended and Restated Articles of Incorporation of DHS.
     11. GUARANTEE OF CERTAIN MANAGEMENT STOCKHOLDERS.
     (a) Pursuant to the terms and conditions of Gold, Rifkin and Kimmel's
respective DHS Employment Agreements, such Management Stockholders are each
required to secure, or to assist the other officers and employees of DHS in
securing, financing for DHS to satisfy DHS' capital requirements as set forth in
its financial projections. The parties hereto have entered into the transactions
contemplated by the Practice Participation Agreement on the assumption that DHS
would receive cash as a result of equity financing in an amount of not less than
$5 million on or before February 28, 1998 (the "FINAL MATURITY DATE").
     (b) If DHS does not receive at least $5 million of cash as a result of
equity financing proceeds by the Final Maturity Date, the amount of equity
financing proceeds actually received by DHS on or before such date shall be
subtracted from $5 million (such positive difference being the "remainder"), and
each of Gold, Rifkin and Kimmel shall present to DHS for cancellation, and DHS
shall immediately cancel that number of shares of Class A Common Stock held by
each such Management Stockholder equal to the product of the number of fully
diluted shares of Class A Common Stock held by such Management Stockholder on
the Closing Date, times a fraction, (i) the numerator of which shall be such
remainder, and (ii) the denominator of which shall be 5 million.
     (c) Each of the parties hereto acknowledges and agrees that any transfer of
shares of Class A Common Stock pursuant to the provisions of this Section 11
shall not be subject to the limitations and restrictions on transfer, and the
rights granted to the other Stockholders and DHS with respect to transfers, as
otherwise provided in Section 5 hereof.

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

transaction in which Capital Stock of DHS is issued in return for cash.
     12. SEVERABILITY. It is the express intention of the parties that the
agreements contained herein shall have the widest application possible. If any
agreement contained herein is found by a court having jurisdiction to be
unreasonable in scope or character, the agreement shall not be rendered
unenforceable thereby, but the parties shall in good faith negotiate a
modification to the agreement that preserves the essence of the agreement of the
parties contained herein with retroactive effect to render such agreement
reasonable and such agreement shall be enforced as thus modified. If the court
having jurisdiction will not review the agreement, then the parties shall
mutually agree to a revision having an effect as close as permitted by law to
the provision declared unenforceable. The parties further agree that in the
event a court having jurisdiction determines, despite the express intent of the
parties, that any portion of any covenant or agreement contained herein is not
enforceable, the remaining provisions of this Agreement shall nonetheless remain
valid and unenforceable.
     13. ENDORSEMENT OF CERTIFICATE. Upon the execution of this Agreement, each
certificate of Stock of DHS now registered in the name of a Stockholder and
subject hereto shall be endorsed by the Secretary of Company as follows:
          "This certificate is transferable only upon compliance with the
     provisions of a restrictive agreement dated September 4, 1996, by and among
     Doctors Health System, Inc. and certain of its stockholders, a copy of
     which is on file in the office of the Secretary of DHS and is available
     upon request of any stockholder without charge."
All certificates for any shares of Stock hereinafter issued to Stockholders
shall bear the same endorsement, and this Agreement shall cover all such stock.
     14. TERM. Anything contained herein to the contrary notwithstanding, this
Agreement shall terminate, and all rights and obligations shall cease, except
for rights and obligations under any then extant promissory note pursuant to
Section 7 hereof, upon the occurrence of any of the following events:
          (i) The written agreement of each of the then parties hereto; or
          (ii) The cessation of DHS' business; or
          (iii) The bankruptcy, liquidation, receivership, or dissolution of, or
     assignment for the benefit of creditors by, DHS;
          (iv) Any Change in Control of DHS; or
          (v) The consummation of any public offering of DHS Capital Stock.
     15. NOTICES. All notices, offers, acceptances, requests and other
communications hereunder shall be in writing and shall be deemed to have been
duly given if delivered or mailed by certified or registered mail to a
Stockholder, as may be required, at their addresses on DHS records, and to DHS
at DHS's principal place of business. Any party hereto may change his or its
address for notice by giving notice thereof in the manner hereinabove provided.
     16. AMENDMENT. Any term or condition set forth in this Agreement may be
amended, modified or altered, and additional terms and conditions may be
incorporated into this Agreement only with the express written consent of all of
DHS and the Stockholders. All of such amendments, modifications, alterations or
additions shall be effective as of the date of such unanimous consent, shall be
in writing, and shall be provided to each of the parties hereto.
     17. MISCELLANEOUS. This Agreement embodies the entire agreement and
understanding among the parties hereto with respect to the subject matter
hereof. This Agreement shall be binding upon, and inure to the benefit of, and
shall be enforceable by, the heirs, successors, assigns, and personal
representatives of the parties hereto. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Maryland, without regard
to principles of conflicts of law. In case any term of this Agreement shall be
held invalid, illegal or unenforceable in whole or in part, neither the validity
of the remaining part of such term nor the validity of the remaining terms of
this Agreement shall in any way be affected thereby. Each of the parties agrees
that he will consent to and approve any amendments of the DHS Amended and
Restated Articles or by-laws of DHS which may be necessary or advisable in order
to conform any of the provisions of this Agreement or any amendments hereto to
the applicable laws of the State of Maryland as now or hereafter enacted. Each
Stockholder agrees to vote his shares of Stock in DHS and to execute and deliver
such documents as may be necessary in order to implement the provisions of the
preceding sentence. Nothing set forth or referred to herein expressed or implied
is intended or shall be
                                      B-14
 
<PAGE>
construed to convey upon or give to any person other than the parties and their
successors or permitted assigns, any rights or remedies under or by reasons of
this Agreement. Each of the Stockholders agrees that, if DHS is able to enter
into any arrangement with a Management Stockholder or another Stockholder,
regarding the repurchase of such Management Stockholder's or other Stockholder's
capital stock that is manifestly more favorable to DHS than the arrangements set
forth herein, to execute and deliver to an amendment to this Stockholders
Agreement reflecting such arrangement.
     18. INTERPRETATION. The parties and their respective legal counsel and
accountants actively participated in the negotiation and drafting of this
Agreement, and in the event of any ambiguity or mistake herein, or any dispute
among the parties with respect to the provisions hereof, no provision in this
Agreement shall be construed unfavorable against any of the parties on the
ground that it or its counsel was the drafter thereof.
     19. WILLS. Each Management Stockholder shall promptly execute a will or
codicil to his will authorizing and directing his personal representatives to
perform all of his obligations under this Agreement, but the failure to execute
such a will shall not affect the rights of the remaining Stockholders or the
obligations of their personal representatives, heirs, descendants, or estates,
as provided in this Agreement.
     20. CANCELLATION OF PRIOR AGREEMENT. This Agreement supersedes and replaces
that certain Stockholders Agreement by and among DHS, the Management
Stockholders, the LP, the Series A Investor and the Series B Investor, dated
December 1, 1995 (the "OLD STOCKHOLDERS AGREEMENT") in its entirety. The Old
Stockholders Agreement is hereby cancelled, rescinded and abrogated.

                    4,100,000 SHARES OF CLASS B COMMON STOCK
               1,000,000 OPTIONS TO PURCHASE CLASS B COMMON STOCK
                            ------------------------
     Doctors Health System, Inc., a Maryland corporation (the "Company"), may
offer and issue from time to time in connection with the affiliation of medical
practices with the Company one or more of the following types of its securities:
(i) shares of its Class B common stock, par value $0.01 per share ("Class B
Common Stock"); or (ii) Options to purchase Class B Common Stock ("Options," and
collectively with the Class B Common Stock, the "Securities"). Securities may be
issued by the Company as consideration in one or a combination of the following
types of transactions: (i) as consideration for acquisitions of certain assets
of medical practices; or (ii) as consideration pursuant to independent practice
association ("IPA") agreements; or (iii) as issuances of Securities pursuant to
employment arrangements between the physician and a Core Medical Group or
between the Company and certain employees. See "Plan of
Distribution--Acquisition of Certain Assets of Medical Practices,"
"--Contractual Arrangements--IPA Arrangements" and "--Contractual
Arrangements--Employment Arrangements." Except in connection with the exercise
of the Options, the Company will not receive cash proceeds in connection with
the issuance of the Securities.
     The Securities offered pursuant to this Prospectus may be issued in amounts
and at prices to be determined at the time of the offering of such Securities.
     It is anticipated that the affiliations of the medical practices will
involve (a) in the case of the acquisition of medical practices, the receipt by
the Company of substantially all of certain assets of such medical practices
(primarily enumerated tangible assets of such practices and related contractual
rights), and (b) in the case of contractual arrangements such as the IPA
arrangements or employment arrangements, the receipt of the contractual
consideration specified in the relevant contract. The consideration for
acquisitions and contractual rights will consist of shares of Class B Common
Stock, cash, Options, assumption of liabilities or a combination of some or all
of them, as determined from time to time by negotiations between the Company and
the physicians or physician groups operating such practices. In addition, such
physicians may enter into employment agreements and IPA participation
agreements, pursuant to which the Company may also issue Securities.
     The terms of an affiliation are determined by negotiations between the
Company's representatives and physicians. Factors taken into account in such
transactions include the established size, quality and reputation of the
practice and with respect to the amount of Securities to be issued the Company's
estimate of the value of the Class B Common Stock. It is anticipated that shares
of Class B Common Stock issued in any such acquisitions will, in most cases, be
valued at a price reasonably related to the current value of the Class B Common
Stock, either at the time the terms of a transaction are tentatively agreed
upon, or at or about the time of closing, or during the period or periods prior
to delivery of the Securities. The value of the Class B Common Stock and the
exercise price of the Options will be determined by the Company's management and
Board of Directors based upon the Company's results of operations and current
financial condition, recent sales of the Company's securities and arms' length
negotiations with potential purchasers, estimates of the business potential and
prospects of the Company, the economics of the health care industry in general,
the general condition of the equity securities markets in general and other
relevant factors. It is not expected that underwriting discounts or commissions
will be paid by the Company (See "Plan of Distribution").
     Certain details as to 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 details will comprise to the extent applicable (1) in
the case of the Options, the number of Options being offered, and the exercise
price of each such Option; and (2) in the case of any offering of Securities,
the offering price, and, to the extent applicable, certain Federal income tax
consequences. With respect to offerings of Securities in connection with the
acquisition of certain assets of medical practices, a Prospectus Supplement will
be provided which will contain information about the specific transaction and
the particular medical practice involved in the transaction. The resale or
transfer of the Securities will be subject to certain restrictions. See
"Description of Capital Stock."
     In the event that, with respect to acquisition transactions, a physician
exercises reacquisition rights granted by the Company with respect to such
Physician's transfer of medical practice assets, the physician will be required
to transfer the Securities issued pursuant to this Prospectus to the Company.
(See "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Development of Integrated Health Care Delivery
System--Reacquisition Rights.")
     This Prospectus may not be used to consummate sales of Securities unless
accompanied by a Prospectus Supplement. The delivery in any jurisdiction of this
Prospectus together with a Prospectus Supplement relating to specific Securities
shall not constitute an offer in such jurisdiction of any other Securities
covered by this Prospectus but not described in such Prospectus Supplement.
     The Securities offered pursuant to this Prospectus will be subject to
significant contractual restrictions or transfer. Further, it is not currently
anticipated that any of the Securities will be listed on an exchange or other
public market. Accordingly, resales of the Securities may be subject to various
regulatory structures which could severely limit the liquidity of the
Securities. There can be no assurance as to the price at which purchasers may be
able to resell the Securities, and such price may be below the value of the
Securities as offered and sold by the Company hereby.
     THIS OFFERING INVOLVES A HIGH DEGREE OF RISK. SEE "RISK FACTORS" BEGINNING

     THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY, AND SUBJECT TO, THE
MORE DETAILED INFORMATION AND FINANCIAL STATEMENTS (INCLUDING THE NOTES THERETO)

CAPITALIZED TERMS USED IN THIS SUMMARY HAVE THE RESPECTIVE MEANINGS ASSIGNED TO
THEM ELSEWHERE IN THIS PROSPECTUS. POTENTIAL INVESTORS SHOULD READ THIS
PROSPECTUS CAREFULLY IN ITS ENTIRETY.
 
THE COMPANY
 
     Doctors Health System, Inc., a Maryland corporation ("DHS" or the
"Company") was incorporated in June of 1994 and commenced operations in February
of 1995. The Company's executive offices are located at 10451 Mill Run Circle,
Owings Mills, Maryland 21117, telephone (410) 654-5800.
 
     The Company is a managed care and medical management company which develops
and consolidates individual and groups of internists, pediatricians and family
practitioners ("primary care physicians" or "PCPs"), specialist physicians,
hospitals and other health care providers into primary care-driven,
comprehensive managed care health delivery networks. Through contracts with
PCPs, specialists, hospitals and other health care providers, the Company
designs its networks: (i) to manage the provision of quality medical services to
patients; (ii) to furnish Network Physicians with access to managed care
contracts and related services while giving them the opportunity to associate
with clinically independent, autonomous medical groups; (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 a managed care company, the Company's primary source of future earnings
is expected to be revenues from Global Capitated Contracts. Under such
arrangements, the Company receives a fixed fee from an HMO or other Payor in
exchange for undertaking the obligation to provide or arrange for the provision
of substantially all of the health care services required by the Enrollees.
These services include not only services provided by the Company's Network
Physicians but also hospitalization, specialty care and ancillary services which
are subcontracted by the Company. The Company's ability to generate earnings is
significantly predicated upon its ability to provide the health care services
for which it contracts at a cost which is less than the fixed fees it receives
under its Global Capitated Contracts. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--General--Source of Revenue and
Earnings." The Company's activities as a managed care company do not subject the
Company to regulation as an HMO because the Company's Global Capitated Contracts
qualify as administrative provider agreements under Maryland law. The Company is
also not subject to regulation as an HMO under Virginia law. See "Risk
Factors--Regulation--Insurance" and "Business--Regulation--Insurance."
 
     As a medical management company, the Company provides to Network Physicians
that join Core Medical Groups certain patient care management, managed care
contracting, and administrative and financial services, including information
systems and billing services, and provides facilities, non-physician staff
personnel, equipment and other goods. See "Business--Managed Care
Contracting,--Practice Management Services,--Control of Patient Data and
Information Systems, and--Care Management." The Core Medical Groups, which
contract with the Company for the provision of these services, engage
exclusively in the practice of medicine through their employed physicians and
maintain autonomy and independence over clinical matters.
 
     Currently, the Company is focusing on the development of its networks in
the Baltimore and Washington metropolitan area and surrounding regions. As of
January 10, 1997, the Company had approximately 1,150 Network Physicians in six
regional networks throughout the state of Maryland and one regional network in
Northern Virginia, including approximately 310 PCPs, 84
obstetrician/gynecologists, and 756 specialist physicians. Of the 1,150 Network
Physicians, 89 were Equity Physicians, of which 69 had transferred certain of
their practice assets to the Company or one of its subsidiaries, 4 had entered
into binding agreements to complete such transactions, and 16 were subject to a
letter of intent. While primary care-based, the Company encourages its Core
Medical Groups to develop into multi-specialty group practices and provides or
arranges financing and other resources to enable such Core Medical Groups to
develop into diversified multi-specialty practices. See "Business--Development
of Integrated Health Care Delivery System."
 
     The Company offers medical groups and independent physicians a variety of
methods of participating in the Company's Integrated Health Care Delivery
System. The Company may acquire certain medical practice assets or certain
contracting rights, either for cash or for Securities, or by execution of a
variety of Independent Physician Association ("IPA") participation agreements.
The Company typically enters into Physician Services Organization Agreements
("PSO Agreements") with the Core Medical Groups, pursuant to which the Company
provides care management, managed care contracting and related business
management services while the Core Medical Groups retain their clinical
autonomy.
 
                                       3
 
<PAGE>
     The Company's strategy is to capitalize upon changes in the health care
industry by: (i) establishing networks of primary care physicians and specialist
physicians to integrate a full spectrum of health care providers into one or
more high quality, cost-effective health care delivery networks; (ii)
transitioning the patients of Network Physicians to the Company's Global
Capitated Contracts; (iii) providing HMOs and other Payors with a single source
of access to geographically proximate networks of physicians and other
providers; (iv) focusing on obtaining Global Capitated Contracts and operating
profitably under a capitated reimbursement system; (v) allowing physicians
greater access to managed care, while relieving physicians of some of the
administrative responsibilities and economic risks of providing managed care
services; (vi) effectively managing the cost and quality of providing care
through the use of sophisticated information systems and a broad range of
practice management and administrative services; and (vii) expanding
aggressively by recruiting additional physicians to networks that have already
been established and by establishing additional networks. See
"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 June 30, 1996 and the three months ended September 30, 1996, the
Company recorded a net loss of approximately $6.6 million and $2.8 million,
respectively. The Company is likely to record a net loss for the year ending
June 30, 1997. At September 30, 1996 the Company had an accumulated deficit of
approximately $12.1 million. There can be no assurance that future operating
losses would not have a material adverse effect on the operating results and
financial condition of the Company. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Results of Operations."
 
LIQUIDITY; RESTRICTIONS ON FINANCING
 
   
     Until the Company and its Payors attract an adequate number of Capitated
Lives in the Company's Global Capitated Contracts, the Company expects to incur
operating losses and experience negative operating cash flows. The Company
believes that its cash on hand at January 15, 1997, the balance remaining
available under the NationsBank Credit Facility, and the anticipated investment
of $5,000,000 in additional preferred stock or receipt of $5,000,000 of
subordinated debt will be sufficient to meet the Company's working capital needs
through June 30, 1997. However, in the event that the Company and its Payors
either have not attracted an adequate number of Capitated Lives in Global
Capitated Contracts sufficient to offset the Company's operating expenses, or
the Company has not secured a substantial amount of additional capital the
Company will not be able to execute its business plan and the Company's
operating results and financial condition would be materially and adversely
affected. There can be no assurance that the Company will be able to secure such
additional capital, or that such capital, if available, will be on terms
favorable to the Company. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity, Cash Flow and Capital
Resources--Subsequent Events."
    
 
     The Company's Series A, Series B and Series C Preferred Stock Directors
have the right under the Company's constituent documents to approve the
incurrence by the Company of indebtedness (including both borrowed money and
capitalized leases) in excess of $1 million beyond the amount budgeted by the
Company from time to time. In addition, the Company's ability to conduct equity
financings may be affected by certain rights of consent of the holders of the
Company's Series A, Series B and Series C Preferred Stock. See "Description of
Capital Stock." There can be no assurance that such holders of Preferred Stock
will grant their consent to the terms of any such financings.
 
UNCERTAINTY OF STRATEGY; ACQUISITION RISKS
 
     The Company's strategy is based upon assumptions relating to the Company's
likely rate of growth of affiliations of medical practices, the rate at which
Capitated Lives can be added to the Company's networks, the likely referral and
other business practices of physicians and health care institutions in the
Baltimore and Washington metropolitan area and surrounding regions, and
assumptions relating to the rate and character of reimbursement for services
provided through the various arrangements negotiated by the Company, including
the continued willingness of Payors to enter into risk sharing arrangements.
Certain of the Company's assumptions may prove to be incorrect, which could have
a material adverse effect on the operating results and financial condition of
the Company. Thus, no assurance can be given that the Company's strategy will be
successfully and profitably implemented.
 
     Further, the Company's strategy depends upon the successful recruitment of
additional physicians to join Core Medical Groups and Exclusive IPAs. There can
be no assurance that the Company will be able to grow in existing or new markets
or successfully identify, complete or integrate any additional acquisitions or
IPA contracts. The process of identifying suitable candidates, and proposing,
negotiating and implementing an economically feasible transaction with a
physician group or forming or managing a physician network, is lengthy and
complex. The Company's strategy involves focusing the development of its
Integrated Health Care Delivery System in the Baltimore and Washington
metropolitan area and surrounding regions. Accordingly, the Company is subject
to and may be adversely affected by any changes in laws and regulations in these
areas pertaining to its business. See "Business--Regulation." Further, currently
substantially all of the Company's net revenues are used to pay for costs of and
in support of the Core Medical Groups and Network Physicians. Thus, the
Company's ability to generate any profit is dependent upon its ability to
transition its Network Physicians and other providers in the Company's provider
networks away from unmanaged fee-for-service compensation arrangements and into
a profitable
 
                                       8
 
<PAGE>
Managed Care environment. The Company will continue to incur operating losses if
it is not able to increase the number of enrollees who are subject to the
Company's Global Capitated Contracts and reduce the number of patients subject
to fee-for-service payment arrangements. The failure of the Company to execute
its strategy effectively could have a material adverse effect on the operating
results and financial condition of the Company. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
REGULATION
 
     GENERAL. While the Company is not currently subject to regulation as an
insurer or health care provider, the insurance and health care business
generally and the Company's business described generally herein are subject to
extensive and pervasive Federal and state regulation pursuant to current
statutes and regulations. Health care regulation has been subject to rapid and
pervasive change in recent years. Congress and various state legislatures are
expected to continue to consider various legislative proposals for health care
reform, including proposals intended to control public and private spending on
health care as well as provide increased public access to the health care system
and maintain broad physician access to health care delivery systems. Changes in
the regulations or reinterpretations of existing regulations may adversely
affect the Company. See "Business--Regulation."
 
     INSURANCE. States heavily regulate the activities of insurance companies.
The Company is not licensed as an insurance company because the Company does not
believe its activities constitute the provision of insurance. 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 by compensating Network Physicians to capitation
payment arrangements may require the Company and such other Managed Care
entities to subject themselves to regulation as insurance companies. There can
be no assurance that the Company's efforts to structure the payment arrangements
with HMOs to conduct itself in such a manner so as not to subject itself to
regulation will be successful, and the imposition of such regulation could have
a material adverse effect on the Company. Regulations which affect the IPAs,
Core Medical Groups, hospitals and other providers of health care could have a
material adverse effect on the operating results and financial condition of the
Company. See "Business--Regulation--Insurance."
 
     MEDICARE FRAUD AND ABUSE RULES. The Company has designed its business
relationships to qualify for "safe harbor protection" under the Medicare Fraud
and Abuse Rules or for an exception under the Federal and state laws discussed
in "Business--Regulation," including federal and state laws which prohibit
"physician self-referrals." 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. For example, there is considerable uncertainty as to
the applicability of the federal legislation known as "Stark II" will apply.
Stark II extends prohibitions against physician self-referrals to a broad list
of services payable under Medicare and Medicaid. 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 Company
has or will have entered, has violated or is violating such laws, or that if any
such assertion were made, that the Company would prevail, or whether any
sanction imposed would have a material adverse effect on the operations of the
Company. Even the assertion of a violation of such laws could have a material
adverse effect on the operating results and financial condition of the Company.
See "Business--Regulation--Medicare and Medicaid Fraud and Abuse Limitations and
- --Regulation--Federal and State Law Regarding Restrictions on Physician
Self-Referral."
 
     TAXATION. The Company enters into contracts with physicians and other
health care providers, who are not employees of Core Medical Groups, as
independent contractors. In accordance with federal and state tax guidelines
pertaining to independent contractors, the Company does 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 operating
results and financial condition of the Company.
 
     CHANGES IN HEALTH CARE REIMBURSEMENT SYSTEMS. 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
 
                                       9
 
<PAGE>
be no assurance that such amendment or change would not have a material adverse
effect on the operating results and financial condition of the Company.
 
INTEGRATION OF OPERATIONS
 
     Since its formation, the Company has grown principally through affiliations
and is pursuing an aggressive growth strategy. If the Company is to realize the
anticipated benefits of acquisitions, the operations of the acquired entities
must be integrated and combined efficiently. The process of integrating the
acquisitions by providing management, financial, administrative, facilities, and
management information systems, while managing a larger and geographically
expanded entity, presents a significant challenge to the management of the
Company. There can be no assurance that the integration process will be
successful or that the anticipated benefits of its business combinations will be
realized. The dedication of management resources to such integration may detract
attention from the day-to-day operations of the Company. There can be no
assurance that there will not be substantial unanticipated costs associated with
such activities or that there will not be other material adverse effects of
these integration efforts. Such effects could have a material adverse effect on
the operating results and financial condition of the Company.
 
DEPENDENCE ON MANAGED CARE CONTRACTS
 
     The profitability of the Company depends on securing and maintaining
contractual relationships with Managed Care plans and other Payors and
successfully managing the expenses involved in the provision of services under
those contracts without sacrificing the quality of medical care. The Company,
not the Core Medical Groups, is the party to the Global Capitated Contracts and
therefore is the recipient of the capitated payments. Such medical expenses are
subject to adverse selection and other utilization risks and are not otherwise
within the Company's or the Core Medical Groups' control. The Company has
entered into three Global Capitated Contracts with two HMOs. The inability of
the Company and its Network Physicians to obtain such contracts or successfully
manage such expenses could have a material adverse effect on the operating
results and financial condition of the Company. In addition, the success of
Payors depends substantially on their ability to reduce, or significantly
restrain the growth of, spending for health care services. Accordingly, there is
a risk that the Company will not be able to obtain or maintain the numbers of
Managed Care contracts presently contemplated or that, if such contracts are
obtained, payments from such Payors will decrease over time, either of which
could have a material adverse effect on the Core Medical Groups or the operating
results and financial condition of the Company. Further, the coverage of the
Managed Care plans with which the Company contracts may be limited to the State
of Maryland, the District of Columbia, Virginia or other limited geographic
regions. There can be no assurance that the coverage of such Managed Care plans
will extend beyond such areas. Finally, the Company's contracts with Payors are
generally for one year and may be terminated earlier upon notice. There can be
no assurance that Managed Care contracts will not be terminated. The loss of any
Payors or the failure to retain such Payors' Enrollees could have a material
adverse effect on the operating results and financial condition of the Company.
 
ENROLLMENT IN MEDICARE MANAGED CARE PLANS
 
     The Company has entered and will enter into Full Risk Contracts and Global
Capitated Contracts with HMOs and other Managed Care Plans covering Medicare
patients. The Company's profitability is highly dependent on the Company's
ability to attract existing patients and new Medicare patients who enroll in the
Medicare Managed Care contracts with licensed HMOs pursuant to Global Capitated
Contracts with the Company. See "Business--Strategy--Medicare Managed Care." The
Company's strategy depends on successful joint marketing efforts by HMOs and the
Company and the willingness of Medicare patients to enroll in Managed Care
plans. There can be no assurance that the Company will be able to successfully
attract a sufficient number of Medicare patients into Medicare Managed Care
plans under contract with the Company or that such patients can be converted in
accordance with the Company's strategy. The failure of the Company to attract a
sufficient number of Medicare patients to Medicare Managed Care plans could have
a material adverse effect on the operating results and financial condition of
the Company.
 
ISSUANCE OF NOTES; SUBSTANTIAL INDEBTEDNESS
 
     The Company intends to place with institutional investors up to $35 million
of senior subordinated notes (the "Notes") and warrants (the "Warrants") to
purchase Class A Common Stock. Assuming the issuance of the Notes, the Company
will have substantial indebtedness in relation to its total capitalization. On a
pro forma basis, after giving effect to the sale of the
 
                                       10
 
<PAGE>
Notes (but not giving effect to the exercise of the Warrants), the Company at
September 30, 1996 would have had approximately $35 million in long-term
indebtedness, and its long-term indebtedness as a percentage of its total
capitalization would have been approximately 66%.
 
     This indebtedness poses substantial risks including the possibility that
the Company might not generate sufficient cash flow to pay the principal of and
interest on its indebtedness. This indebtedness may also adversely affect the
Company's ability to finance its future operations and capital needs, limit its
ability to pursue other business opportunities and make its results of
operations more susceptible to adverse economic conditions. All of the foregoing
could have a material adverse effect on the operating results and financial
condition of the Company.
 
     The terms of the agreements with holders of the Notes are expected to
include significant restrictive financial and operating covenants that, among
other things, will limit the ability of the Company to incur certain additional
indebtedness and pay dividends or make other distributions on its capital stock.
In the event of liquidation of the Company, the holders of the Notes and other
holders of indebtedness of the Company are expected to have priority of payment
over the holders of the Company's common stock. There can be no assurance that
the Company will consummate the sale of the Notes and Warrants or, in the event
that such Notes or Warrants are issued, that such issuance will be made on
expected terms.
 
RISKS OF CHANGES IN PAYMENT FOR MEDICAL SERVICES
 
     The profitability of the Company may be adversely affected by Medicare and
Medicaid regulations, cost containment decisions of Payors and other payment
factors over which the Company has no control. The Federal Medicare program has
undergone significant legislative and regulatory changes in the reimbursement
and fraud and abuse areas, including the adoption of the resource-based relative
value scale ("RBRVS") schedule for physician compensation under Medicare, which
may have a negative impact on the Company's revenue. Efforts to control the cost
of health care services are increasing. Future profitability in the changing
health care environment, with differing methods of payment for medical services,
is likely to be affected significantly by management of health care costs,
pricing of services and agreements with Payors. Because the Company derives its
revenues from the revenues generated by Network Physicians, further reductions
in payments to physicians generally or other changes in payment for health care
services could have a material adverse effect on the operating results and
financial condition of the Company.
 
     HCFA recently announced its intention to conduct an experimental pilot
program designed to reduce expenditures under Medicare Managed Care plans in
selected areas, including the Baltimore metropolitan area. The effect of any
such experimental program, if implemented, cannot be predicted, but could have a
material adverse effect on the operating results and financial condition of the
Company. See "Business--Regulation."
 
DEPENDENCE OF THE COMPANY ON CORE MEDICAL GROUPS AND IPAS
 
     The Company enters into Managed Care contracts with Payors pursuant to
which the Company agrees to arrange for the delivery of medical services to
Enrollees in exchange for Managed Care compensation. The Company does not own
any equity interest in the Core Medical Groups or engage in the practice of
medicine and will be largely dependent upon medical services provided by Network
Physicians for its Managed Care revenues. The success of the Company initially
will be dependent in large part upon its ability to attract Network Physicians
to join Core Medical Groups or to participate in IPA arrangements with the
Company, and upon the Core Medical Groups' and the Network Physicians' ability
to deliver high quality patient care in a cost-efficient manner. There can be no
assurance that the Company will be able to attract and retain the requisite
number of PCPs and specialist physicians, or that such physicians will deliver
high quality medical services profitably, either of which could have a material
adverse effect on the operating results and financial condition of the Company.
Because each Core Medical Group and independent IPA retains its clinical
autonomy and operates as a separate legal entity, there can be no assurance that
physicians employed by the Core Medical Groups and the other Network Physicians
will perform high quality, cost-effective medical services, the failure of which
could have a material adverse effect on the operating results and financial
condition of the Company.
 
     The Company enters into a PSO Agreement which obligates the Core Medical
Group to contract solely and exclusively with the Company for 30 years (with
automatic ten-year renewals) for all managed care contracts, and for the
provision of all of the non-medical services, including provision of facilities,
equipment, supplies and other goods and assets, used by the Core Medical Groups
and their employee physicians to engage in the practice of medicine. See
"Business--Development of Integrated Health Care Delivery System--Focus on
Primary Care Physicians." There can be no assurance that the Company will be
able to meet its contractual obligations to the Core Medical Groups in a manner
that is reasonably acceptable to the
 
                                       11
 
<PAGE>
Core Medical Groups. A failure of the Company to meet its contractual
obligations could result in the termination of such arrangements, which could
have a material adverse effect on the operating results and financial condition
of the Company.
 
RISKS ASSOCIATED WITH CAPITATION PAYMENTS FOR MEDICAL SERVICES
 
     As an increasing percentage of patients are being placed under the control
of managed care entities, the Company believes that its success will, in large
part, be dependent upon the Company's ability to negotiate contracts with HMOs
pursuant to which services will be provided on a risk-sharing or capitated basis
by the Company. The Company has entered into three Global Capitated Contracts
with two HMOs and intends to expand the number of Global Capitated Contracts or
Full Risk Contracts in which it participates and convert medical services
currently compensated on a fee-for-service basis to capitation arrangements.
Under the Company's Global Capitated Contracts, the Company accepts a
predetermined amount per Enrollee per month (capitation) to provide to Enrollees
of the HMO who select a Network PCP all necessary covered services covered under
the Global Capitated Contract. Such contracts pass much of the business risk of
providing care, such as overutilization, from the HMO to the Company. The
proliferation of such contracts in markets served by the Company could result in
greater predictability of revenues, but greater unpredictability of expenses.
There can be no assurance that the Company will be able to negotiate, generally
on behalf of the Company, satisfactory arrangements on a risk-sharing or
capitated basis. In addition, to the extent that patients or Enrollees covered
by such contracts require more frequent or extensive care than is anticipated,
the Company's operating margins may be reduced, or in the worst case, the
revenues derived from such contracts may be insufficient to cover the costs of
the services provided. As a result, the Company may incur additional costs,
which would reduce or eliminate anticipated earnings under such contracts. Any
such reduction or elimination of earnings could have a material adverse effect
on the Company's results of operations.
 
     In addition, the Company is dependent upon the collection of
fee-for-service revenues attributable to the medical practices of the Core
Medical Groups because a portion of such revenues are necessary to pay the
expenses of the Core Medical Groups medical practice operations. The Company is
liable for providing office space, personnel billing and collection services,
and other bookkeeping and management services to the Core Medical Groups and the
Company relies on the fee-for-service revenues and other capitation revenues to
pay the cost of these services. Failure of the Core Medical Groups to earn
sufficient revenues to fund such costs, would have a material adverse effect on
the Company.
 
     The Company enters into Global Capitated Contracts or Full Risk Contracts
only with licensed HMOs and would only enter into such contracts with licensed
insurance companies and HMOs only if allowed by state law of any particular
state. To the extent such contracts are prohibited by law or in any particular
state, the Company would not enter into such contracts in that state. In 1995,
the National Association of Insurance Commissioners (the "NAIC") issued a report
opining that such risk-sharing arrangements might constitute the business of
insurance, to which state insurance licensing laws may apply. The NAIC further
opined that such state licensing laws would not apply if the unlicensed entity,
such as the Company, contracts to assume "downstream risk" from a duly licensed
health insurer or HMO for health care provided to that insurance carrier's
Enrollees. The NAIC's conclusions are not binding on the states. Maryland's
attorney general has opined, in writing, that the arrangements with HMOs similar
to the Company's are not subject to regulation as an insurer under Maryland law.
 
     If the Company were to be regulated as an insurer because it accepts
capitation payments, the Company would be subject to substantial additional
costs to comply with state regulations, including the maintenance of substantial
reserves, which would 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 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, and companies that actually own all or some portion of medical
groups. Such competitors may include local, regional and national entities.
 
     Some of these companies provide traditional management services to primary
care, multi-specialty and specialty physician groups, while other companies
provide claims processing, utilization review and other more focused management
services. Some competitors are significantly larger and better capitalized than
the Company and have access to greater resources, provide a wider variety of
services, have greater experience in providing health care management services,
have longer established relationships with buyers of such services than does the
Company, and, through actual ownership of
 
                                       12
 
<PAGE>
physicians and medical groups, can exercise more pervasive control over the
clinical activities of the medical groups 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 certain
assets of or contract with physician practices. Such competition could increase
the cost of making such acquisitions and contracts and could endanger the
success of the Company's strategy of acquiring or contracting with PCPs in
selected markets. There can be no assurance that the Company will be able to
acquire certain assets of or contract with a sufficient number of physician
practices and thereby compete favorably in contracting with Payors or to expand
or maintain its physician networks in existing or new markets. Any of the
foregoing could have a material adverse effect on the operating results and
financial condition of the Company.
 
DILUTION
 
     The Company contemplates that it will acquire additional medical practices
for existing Core Medical Groups and will organize additional Core Medical
Groups. The Company also contemplates contracting with additional physicians
through IPAs and other arrangements and compensating IPAs for recruiting their
IPA Participant Physicians to contract with the Company. The Company may issue
Securities in connection with any of such transactions. The Company may make
such acquisitions and contracts if it believes, in the exercise of its
discretion, that such acquisitions are beneficial, and without any requirement
that the Company's stockholders approve such transactions, all on terms as may
be negotiated by the Company. In addition, the Company intends to obtain
additional financing, some of which could result in dilution to the then
existing Stockholders. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity, Cash Flow and Capital
Resources--Subsequent Events."
 
     Accordingly, the percentage ownership interest of each then existing
stockholder in the Company will be reduced proportionately and, depending upon
the valuation at which such securities are issued, such issuances may be
dilutive to the then existing stockholders. Although the Company contemplates
that additional securities will be issued in the future, there can be no
assurance as to the number, if any, of new physicians, IPAs or investors who
will become stockholders of the Company.
 
INTANGIBLES
 
     As a result of the Company's acquisitions during 1995 and 1996, intangibles
increased from $23,104 as of June 30, 1995 to $2,886,235 as of September 30,
1996. The Company's policy is to amortize intangibles over a 10 to 40 year
period. The intangibles acquired during fiscal 1995 and fiscal 1996 are being
amortized over 20 years using the straight-line method in the Company's
consolidated financial statements. Such amortization is expected to
significantly affect the Company's profitability in the near term. In addition,
the Company's future acquisitions may generate additional intangibles. As
required under generally accepted accounting principles, the Company reviews the
carrying value of intangibles at each reporting period to determine if facts or
circumstances exist which suggest that intangibles may be impaired. If
impairment is determined to have occurred, intangibles will be adjusted
downward. There can be no assurance that impairment of intangibles with respect
to the Company's acquisitions will not occur. Such adjustment, if required,
could have a material adverse effect on the operating results and financial
condition of the Company. See Note 3 to Notes to Consolidated Financial
Statements.
 
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., J. David Nagel, M.D., Howard
Goldman, M.D. 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., William D. Lamm, M.D., Mark Eig, M.D., and Robert Graw, Jr., M.D.,
Directors of the Company, are also the respective Chairmen of Carroll Medical
Group, LLC, Cumberland Valley Medical Group, LLC, Doctors Health Montgomery,
LLC, and Anne Arundel Medical Group, LLC. Such members of management of the
Company from time to time may find it necessary take certain actions contrary to
the interests of the Core Medical Group physicians (which may include such
members of management), including decisions with respect to compensation of
physicians (setting of reimbursement rates for physicians and bonus pools), and
reimbursement for inappropriate utilization of medical services. 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."

VOTING LIMITATIONS; RESTRICTIONS ON RESALE OF SECURITIES
 
     Each of the classes of Common Stock is entitled to elect a certain number
of the Company's directors and has its own particular voting requirements. The
holders of the Class A Common Stock are entitled to elect five of the Company's
18 directors (each a "Class A Director") by an affirmative vote of a plurality
of all votes cast at a meeting at which a quorum of Class A Common Stock is
present. The holders of the Class B Common Stock are entitled to elect eight of
the Company's 18 directors (each a "Class B Director") by an affirmative vote of
a plurality of all votes cast at a meeting at which a quorum of Class B Common
Stock is present. The holders of the Series A Preferred Stock are entitled to
elect two of the Company's 18 directors (each a "Series A Preferred Director")
by an affirmative vote of a plurality of all votes cast at a meeting at which a
quorum of Series A Preferred Stock is present. The holders of the Series B
Preferred Stock are entitled to elect two of the Company's 18 directors (each a
"Series B Preferred Director") by an affirmative vote of a plurality of all
votes cast at a meeting at which a quorum of Series B Preferred Stock is
present. Prior to the Company's 1998 annual meeting, the holders of the Series C
Preferred Stock are entitled to elect one of the Company's 18 directors (each a
"Series C Preferred Director") by an affirmative vote of a plurality of all
votes cast at a meeting at which a quorum of Series C Preferred Stock is
present. At the Company's 1998 annual meeting of stockholders, the number of
directors of the Company shall be increased to 19, and thereafter, the holders
of the Series C Preferred Stock will be entitled to elect two of the Company's
directors. Upon conversion of all of the Series A, Series B and Series C
Preferred Stock to Class C Common Stock, the holders of shares of Class C Common
Stock shall be entitled to elect five directors of the Company prior to the
Company's 1998 annual meeting and six directors thereafter (each a "Class C
Common Director"). Further, the Company must obtain the consent of the holders
of the Company's Series A, Series B and Series C Preferred Stock (collectively,
the "Preferred Stock") in connection with a variety of significant corporate
activities. All of the Company's stockholders (with the exception of employee
participants in the Company's Omnibus Stock Option Plan which, by its terms,
restricts in certain ways the resale of stock issued thereunder) are parties to
a Stockholders Agreement which governs a variety of matters, including voting as
to directors. Purchasers of Securities will also be subject to significant
contractual restrictions on the resale of such Securities until an underwritten
initial public offering for cash of Common Stock, and all shares will carry a
legend to reflect such restrictions. There can be no assurance that such an
offering will occur. See "Management--Stockholders Agreement" and "Description
of Capital Stock."
 
ABSENCE OF PUBLIC MARKET
 
     It is not currently anticipated that any of the Securities described in
this Prospectus will be listed on an exchange or other public market or that a
trading market will develop for the Securities. Consequently, the price of the
Securities which may be obtained by a seller in a secondary resale may be
subject to volatility, and given the contractual restrictions or transfer
described in "--Voting Limitations; Restrictions on Resales of Securities" and
"Description of Capital Stock," the resale of such Securities may be difficult
to effect in any case.
 
PENNY STOCK RULES
 
     As described in "--Absence of Public Market," it is not currently
anticipated that any of the Securities described in this Prospectus will be
listed on an exchange or other public market or that a trading market will
develop for the Securities. As it is not expected that any of the Securities
will be traded on an exchange or quoted on Nasdaq, the Securities will be
subject to Rule 15g-9 under the Exchange Act, which, among other things,
requires that brokers/dealers satisfy special sales practice requirements,
including making individualized written suitability determinations and receiving
any purchaser's written consent prior to any transaction. If the Securities
could also be deemed penny stocks under the Securities Enforcement and Penny
Stock Reform Act of 1990, this would require additional disclosure in connection
with trades in the Securities, including the delivery of a disclosure schedule
explaining the nature and risks of the penny stock market. Such requirements
could severely limit the liquidity of the Securities and the ability of the
purchasers in this offering to sell their Securities in the secondary market.
 
FEDERAL AND STATE REGISTRATION REQUIREMENTS; POSSIBLE INABILITY TO EXERCISE
OPTIONS
 
     Holders of Options will have the right to exercise such option only if
there is a current registration statement in effect with the Commission relating
to the shares of Class B Common Stock issuable upon exercise of the Options and
such shares are qualified with or approved for sale by various state securities
agencies, or if, in the opinion of counsel for the Company, there is an
effective exemption from registration. There can be no assurance that the
Company will be able to keep a registration statement covering the shares
underlying the Options current. If a registration statement covering such shares
of Class B Common Stock is not kept current for any reason, or if the shares
underlying the Options are not registered in the state in
 
                                       14
 
<PAGE>
which a holder resides, the Options will not be exercisable and will be deprived
of any value. See "Description of Capital Stock--Options."
 
OWNERSHIP OF STOCK BY DIRECTORS AND EXECUTIVE OFFICERS
 
     The executive officers and directors of the Company own 98.8% of the Class
A Common Stock of the Company (which as of January 10, 1997 represents
approximately 15% of the outstanding capital stock of the Company). The holders
of Class A Common Stock are entitled to elect five of the 18 members of the
Board of Directors.
 
     The executive officers and directors of the Company own, either directly or
indirectly through their equity interests in Medical Holdings Limited
Partnership ("MHLP") approximately 18.1% of the Class B Common Stock (which as
of January 10, 1997 represents approximately 8.8% of the Company's outstanding
capital stock). Five directors of the Company own approximately 29.4% of the
issued and outstanding capital stock of BMGGP, Inc., the general partner of
MHLP. MHLP owns 84.8% of the Company's issued and outstanding Class B Common
Stock (which as of January 10, 1997 represents approximately 41.3% of the
outstanding capital stock of the Company). The holders of Class B Common are
entitled to elect eight of the 18 members of the Board of Directors.
 
     Two directors of the Company are executive officers of St. Joseph Medical
Center, the holder of Series A Preferred Stock. The holder of Series A Preferred
Stock is entitled to elect two of the Company's directors. One director of the
Company is a director of the parent company of Med-Lantic Management Services,
Inc., the holder of Series B Preferred Stock. The holder of Series B Preferred
Stock is entitled to elect two of the Company's directors. One of the directors
of the Company is an executive officer of Genesis Health Ventures, Inc., the
holder of Series C Preferred Stock. The holder of Series C Preferred Stock is
entitled to elect one of the Company's directors. As of January 10, 1997, the
holder of the Series A Preferred Stock owns approximately 18.8% of the Company's
outstanding capital stock on an as converted basis, the holder of the Series B
Preferred Stock owns approximately 6.7% of the Company's outstanding capital
stock on an as converted basis, and the holder of the Series C Preferred Stock
owns approximately 10.7% of the Company's outstanding capital stock on an as
converted basis. As of January 10, 1997, the holders of Class C Common Stock
would together own approximately 36.2% of the Company's outstanding capital
stock on an as converted basis.
 
     Accordingly, the executive officers and directors may have a significant
impact on the business, policies and affairs of the Company. See "Principal
Stockholders".
 
KEY EMPLOYEES
 
     The Company depends to a significant extent on key management, technical
and marketing personnel, and depends particularly on the efforts of Mr. Gold and
Drs. Rifkin and Kimmel. The Company's growth and future prospects will depend in
large part upon its ability to attract, motivate and retain highly qualified
personnel. The loss of any key personnel or the inability to hire or retain
qualified personnel could have a material adverse effect on the operating
results and financial condition of the Company. See "Management."
 
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 PSO Agreements for
liabilities resulting from the negligent performance of services or other
misconduct by such Core Medical Group members. Although the Company currently is
not a party to any material litigation relating to the practice of medicine,
there can be no assurance that the Company will not become involved in such
litigation in the future, that any claim or claims arising from such litigation
will not exceed the Company's insurance coverage or that such coverage will
continue to be available, any of which could have a material adverse effect on
the Company.

ANTI-TAKEOVER CONSIDERATIONS
 
     Certain provisions of the Company's Articles of Incorporation and Bylaws
and agreements to which the Company is a party could, together or separately,
discourage potential acquisition proposals or delay or prevent a change in
control of the Company, even when stockholders other than the Company's
principal stockholders consider such a transaction to be in their best interest.
For example, the Company's outstanding stock options to management and employees
will vest upon a change in control of the Company, thereby potentially diluting
the equity ownership of a purchaser of the Company's securities. The Company's
Articles of Incorporation require, in certain instances, the approval of the
holders of Series A and Series B Preferred Stock of the sale by the Corporation
of all or substantially all of its assets, of certain mergers, and certain
public offerings of the Company's common stock. Accordingly, such provisions may
limit the price that certain investors might be willing to pay in the future for
Securities. See "Description of Capital Stock" and "Management--Stockholders
Agreement."
 
ANTITRUST CONSIDERATIONS
 
     The Company and its Network Physicians, and other entities with which it
contracts are subject to the United States, state and District of Columbia
antitrust statutes as well as to the interpretations of such statutes by the
courts. Because the Company will be contracting with Payors and with providers
for the provision of health care services by providers who could be deemed to
compete for the provision of such services, and for other reasons, the Company,
Network Physicians and other entities with which it contracts could be subject
to public and private investigations and enforcement actions under such
statutes. The health care sector is undergoing significant change and is highly
competitive. See "Risk Factors--Competition." The Company has consulted with
counsel concerning the appropriateness of its contracting activities under such
statutes and believes that all of its present and proposed activities are
consistent with such statutes and interpretive guidelines issued by the
Department of Justice, the Federal Trade Commission and other regulatory
agencies. There can, however, be no assurance that the Company will not be
challenged on these grounds.
 
                                USE OF PROCEEDS
 
     Securities may be issued from time to time in connection with the
affiliation of medical practices by the Company and in certain related
circumstances described in "Plan of Distribution". In exchange for such
Securities (and other consideration), the Company expects to receive certain
enumerated assets of such practices or the consideration specified in the
relevant contract. The Company will issue Securities only in connection with the
affiliation of medical practices by the Company and in such related
circumstances and will not, except in connection with the exercise of the
Options, receive cash proceeds in connection with the issuance of the
Securities. See "Plan of Distribution--Acquisition of Certain Medical
Practices," "--Contractual Arrangements--IPA Arrangements" and "--Contractual
Arrangements--Employment Arrangements".

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
     OVERVIEW. As of September 30, 1996, there were approximately 690 Network
Physicians in five regional networks throughout the State of Maryland, including
approximately 176 PCPs, 95 obstetrician/gynecologists and 419 specialist
physicians. Of these, 90 were Equity Physicians, of which 51 had transferred
their practice assets to the Company or one of its subsidiaries and 23 had
entered into binding agreements to complete such transactions and 16 were
subject to a letter of intent. As of January 10, 1997, there were approximately
1,150 Network Physicians in six regional networks throughout the state of
Maryland and one regional network in Northern Virginia, including approximately
310 PCPs, 84 obstetrician/gynecologists, and 756 specialist physicians. Of the
1,150 Network Physicians, 89 were Equity Physicians, of which 69 had transferred
their practice assets to the Company or one of its subsidiaries, 4 had entered
into binding agreements to complete such transactions, and 16 were subject to a
letter of intent.
 
     The Company provides services to its Network Physicians, who deliver health
care services to patients under various reimbursement mechanisms. The Company's
level of profitability depends on (i) increasing the number of Network
Physicians, (ii) attracting patients to enroll in benefit plans that enter into
Global Capitated Contracts with the Company (principally Medicare
beneficiaries), (iii) securing additional and maintaining Global Capitated
Contracts, with adequate reimbursement rates and (iv) generating earnings
through assisting Network Physicians in managing the delivery of high quality
care at a cost less than the reimbursement received under Global Capitated
Contracts.
 
     SOURCE OF REVENUES AND EARNINGS. The Company's total revenues represent (i)
the contractual management and similar fees earned under its long-term PSO
Agreements with Core Medical Groups ("Net Revenues") and (ii) payments made by
Payors to the Company pursuant to Full Risk Contracts or Global Capitated
Contracts and Gatekeeper Capitation Contracts ("Capitation Revenue"). Under the
PSO Agreements, the Company is contractually responsible and at risk for the
operating costs of the Core Medical Groups with the exception of amounts
retained by physicians for their salaries. Because the Company owns no equity
interest in the Core Medical Groups and is not engaged in the practice of
medicine, the Company does not reflect physician revenues in the Company's
financial statements. The Company's Net Revenues include the reimbursement of
all medical practice operating costs and the contractual management fees
pursuant to the PSO Agreements and other agreements. Net Revenue is recognized
when services are performed and collection from the Core Medical Groups is
probable.
 
     The Company acquires certain assets of medical practices from Equity
Physicians and enters into long-term contracts with Core Medical Groups who
employ the physicians. The Company currently derives a significant portion of
its Total Revenues pursuant to the PSO Agreements, which are long-term contracts
between Core Medical Groups and the Company. The Company's PSO Agreements have a
30-year term with an unlimited number of 10-year renewals and provide that the
Company and the Core Medical Groups will each perform certain duties with
respect to operation of the Company's Integrated Health Care Delivery System.
The Company agrees to provide the Core Medical Groups with general management
services (including financing, marketing, advertising, budgeting, physician
acquisition, information systems, and bookkeeping); billing and collection of
patient care fees; office personnel; equipment and office space; maintenance of
patient records and other medical practice management services. Under the PSO
Agreements, the Core Medical Groups agree to comply with the terms of Managed
Care Contracts, including the delivery of health care services, 24-hour
coverage, cooperation with utilization review, quality assurance and peer review
programs and credentialing matters.
 
     As consideration for the services, assets, and facilities provided by the
Company, the Core Medical Groups in the PSO Agreements typically agree to pay
the Company the cost of services, assets and facilities provided by the Company
to the Core Medical Groups. Such amounts paid to the Company are reflected in
the Company's financial statements as Net Revenues.
 
     In addition, pursuant to the PSO Agreements, the Company typically is
entitled to compensation from the Core Medical Groups calculated by subtracting
the costs of operating the Core Medical Groups' medical practices (including
physician salaries) from the Core Medical Groups' income. To date, the Company
has not received any revenues pursuant to this provision of the PSO Agreements.
 
     As described in "Business--Development of Integrated Health Care Delivery
System--PSO Agreement with the Core Medical Group," PSO Agreements with PCP Core
Medical Groups provide that the Company may pay to the Core Medical Group, as a
Managed Care Incentive Payment, an annual negotiated amount of up to 25% of the
total amount of all Company net income before taxes and bonuses, attributable to
the provision of health care to the Core Medical Group's managed care
 
                                       18
 
<PAGE>
patients during each calendar year, not to exceed, in the aggregate, 25% of the
base salaries paid to all PCPs of the Core Medical Group. Such payments are not
required if the Company has not earned net income during the applicable years.
To the extent that the Company records net income in the future, such payments
may be expected to have an effect on its results of operations.
 
     The PSO Agreement for Doctors Health Montgomery, LLC provides a different
method of calculating the Company's compensation. The Company is entitled to
retain as its compensation 40% of an amount determined by subtracting the fees
received from the provision of ancillary medical services by the Core Medical
Group, including laboratory and radiology services, from the direct costs of
providing these services. In addition, the Company is entitled to a "practice
growth amount," equal to the amount derived by subtracting (i) the Core Medical
Group physician's salary guarantee from (ii) the excess of physician revenues
over expenses of the physician's medical practice. The Company is entitled to
38% of this practice growth amount which reflects growth in the practice because
the physician's salary guarantee is based upon an average of the two prior years
net revenues. The Company's financial relationship with each practice offers the
physicians access to capital, management expertise, sophisticated information
systems and Managed Care contracts.
 
     The historical results of operations presented herein are not necessarily
indicative of anticipated future results. Physicians, prior to becoming
employees of the Core Medical Groups, derived substantially all of their
revenues through activities related to Net Revenue. A central tenet of the
Company's strategy is changing the revenue mix of its Network Physicians from
fee-for-service reimbursement to pre-paid arrangements, principally those
involving Global Capitated Contracts for Medicare beneficiaries.
 
     The Company's primary source of future earnings is expected to be Global
Capitation Revenue. Under such arrangements, the Company receives a fixed fee
from a Payor in exchange for undertaking the obligation to provide or arrange
for the provision of substantially all of the health care services required by
the Enrollees (the majority of expenses associated with such activities are
reported as "Medical Services Expense"). These services include not only
services provided by the Company's Network Physicians but also hospitalization,
specialty care and ancillary services which are subcontracted by the Company.
The Company expects to realize reimbursement rates of approximately $4,000 to
$5,000 per year per Medicare patient and approximately $1,000 under Commercial
Capitated Contracts.
 
     Due to the Company's strategy of seeking future earnings from Global
Capitated Contracts and Full Risk Contracts, the Company is exposed to certain
financial risks. Under these arrangements, the Company is responsible through
its Network Physicians, for the provision of certain covered medical services
including primary care and specialist services and hospitalization. The Company
does not control the medical decisions made by health care providers. However,
in accordance with the policies and procedures established by the HMOs and other
Payors, the Company communicates whether requested services are covered pursuant
to an Enrollee's HMO or other managed care plan. To the extent that Enrollees
require more care than may be anticipated or require care that is not reimbursed
by the HMO, aggregate capitation payments received by the Company may not be
sufficient to cover the costs of treating the Enrollees. If the capitation
revenue is not sufficient to cover the costs, the Company's revenues would be
adversely affected. The Company has had limited historical experience under
capitated arrangements because the Company's three Global Capitated Contracts
were effective January 1, April 1 and June 1, 1996. During this limited period
of time operating under such contracts, the Company has recognized a loss of
approximately $280,000 for the year ended June 30, 1996. For the three months
ended September 30, 1996, the Company recorded approximately $927,000 in
revenues with respect to Global Capitated Contracts and a profit of
approximately $72,000 with respect to such contracts.
 
     The inability of the Company to renew its current Payor contracts, to
maintain favorable terms of such contracts, to attract patients who enroll in
such benefit plans, to expand such contracts to other geographical areas in the
Baltimore and Washington metropolitan area and surrounding regions or to manage
successfully the cost of care would materially and adversely affect the
Company's revenues and primary source of earnings.
 
     As of January 10, 1997, the Company is working cooperatively with two
Payors to attract both Medicare and commercial patients who enroll in benefit
plans that enter into Global Capitated Contracts with the Company. As of
September 30, 1996 and as of January 10, 1997, there were not a sufficient
number of patients enrolled in benefit plans under the Company's Global
Capitated Contracts to cover its operating costs. To the extent patients do not
enroll in such benefit plans in adequate numbers, it will have a material
adverse effect on the operating results and financial condition of the Company.
 
                                       19
 
<PAGE>
     The Company's ability to manage successfully the cost of care under such
contracts depends on the overall health of its patients, its ability to manage
appropriate and timely utilization of medical resources in coordination with the
clinical decision-making authority of individual physicians and its ability to
maintain favorable agreements with other health care providers (E.G., hospital
and ancillary services). To the extent the Company is unable to provide or
arrange for the provision of substantially all of the health care services
required by its patients at a cost less than the fixed fee received from a
Payor, it will have a material adverse effect on the operating results and
financial condition of the Company.
 
     In the future, the Company expects to derive meaningful revenues and
earnings from other sources including (i) the management of Specialty Care Core
Medical Groups, (ii) the management fees growth of multi-specialty Core Medical
Group revenue, (iii) other management fees and (iv) the growth of Core Medical
Groups revenue from increased physician productivity.
 
     ACQUISITIONS/OTHER PHYSICIAN TRANSACTIONS. The Company has acquired the
furniture, fixtures and equipment (at net book value, which the Company and each
Equity Physician agree approximates fair value), intangible assets, and the
accounts receivable of certain medical practices in exchange for consideration
of cash, stock and/or notes payable. In addition to such consideration,
substantially all direct costs associated with the acquisition are capitalized.
(See "History of the Company" for a description of the number of practices
acquired and the amount and form of consideration paid to consummate each
transaction.) The Company acquires no equity interest in the Core Medical Groups
that employ the Equity Physicians.
 
     At the time of acquisition, Equity Physicians typically enter into 10-year
employment agreements with a Core Medical Group. Further, each Core Medical
Group enters into a PSO Agreement with the Company generally for 30 years, with
automatic terms of renewal, pursuant to which the Company provides management
and administrative services to the Core Medical Group and the Core Medical Group
agrees to provide medical services to the Company's patients. The PSO Agreement
does not convey any equity interest in the Core Medical Groups, which retain
autonomy and independence over clinical matters.
 
     Certain acquisitions are subject to reacquisition rights whereby the
physicians may rescind the transaction typically within a nine month period from
the date of closing. Pursuant to such reacquisition rights, such physicians may
repurchase substantially all of the assets previously acquired at the price paid
by the Company at the closing. To date, one physician had exercised his
reacquisition rights. In that instance, the practice had not actually been
consolidated into the operations of the Company and as a consequence had no
material financial effect on the Company. As of September 30, 1996, of the 44
physicians who had been granted reacquisition rights, 17 had such rights still
available. These physicians represented approximately $1,511,905 or 20% of the
Company's total pro forma revenue of $7,579,000. As of January 10, 1997, of the
58 physicians who had been granted reacquisition rights, 19 had such rights
still available. Although the Company does not believe that substantial
rescissions will occur, the exercise of such rights by a substantial number of
physicians would have a material and adverse effect on the operating results and
financial condition of the Company.
 
     As of September 30, 1996, 23 of the Equity Physicians had entered into
binding letters of intent to sell certain assets of their medical practices to
the Company and become employees of Core Medical Groups. As of January 10, 1997,
19 of these physicians had consummated the aforementioned transactions. The
Company expects the remainder of these transactions to close in 1997.
 
     The Company intends to continue acquiring certain assets of medical
practices and obtaining managed care contracting rights and is currently in
active discussions with a number of primary and specialty care physicians. The
Company intends to begin management of multi-specialty Core Medical Groups
pursuant to a medical practice asset acquisition of and merger with a cardiology
practice and the integration of such physicians as the Cardiology Department of
an existing Core Medical Group. The consideration in such transaction will
consist of shares of Class B Common Stock and deferred compensation for the
accounts receivable.
 
     The Company also expects to derive revenues and earnings from the
participation of physicians in its IPAs. As of September 30, 1996, 50 Network
PCPs were participants in the Company's IPAs. As of January 10, 1997, 186
Network PCPs were participants in the Company's IPAs. (See
"Business--Development of Integrated Health Care Delivery System--Independent
Physician Associations".)

RESULTS OF OPERATIONS
 
     The Company's operating results are significantly affected by the number of
Network PCPs, the number of Network PCPs participating in Global Capitated
Contracts, the number of executed Global Capitated Contracts, and the number of
patients enrolled in benefit plans under Global Capitated Contracts with the
Company. The following table summarizes the Company's history with respect to
Network PCPs, executed Global Capitated Contracts and patients enrolled in
benefit plans under Global Capitated Contracts with the Company:

- ---------------
* There is a lag between when physicians join networks and when they become
  eligible to participate in Global Capitated Contracts as a result of the
  credentialing process and other internal Company controls.
 
     The increase in the number of Network Physicians has contributed to the
increase in net revenue growth as well as the increase in operating costs to
support physician growth. In preparation for the acquisition of medical
practices and other physician transactions, the Company had invested in the
personnel and infrastructure necessary to accommodate its anticipated growth,
which resulted in substantial increases in corporate expenses throughout 1996
and 1995.
 
     The Company's three Global Capitated Contracts noted above were effective
January 1, April 1 and June 1, 1996, respectively. Since the Company executed
its Global Capitated Contracts in the latter half of the year ended June 30,
1996 and its Network PCPs experienced the lag time in becoming eligible to
participate in such contracts, the Company's global capitated revenue was less
than expected.
 
     Due to the limited operating period of the Global Capitated Contracts, the
number of physicians eligible to participate in Global Capitated Contracts, the
resulting relatively small number of patients enrolled in benefit plans under
Global Capitated Contracts with the Company and the Company's limited experience
with the Payors, the Company has recognized a loss of approximately $280,000
related to such contracts for the year ended June 30, 1996. For the three months
ended September 30, 1996, the Company has recorded approximately $927,000 Global
Capitated Revenue and recognized a profit related to such contracts of
approximately $72,000.
 
     Although the Company expects that it will derive earnings from such
contracts in the future given larger numbers of Network PCPs participating in
Global Capitated Contracts, the expected larger number of enrolled patients and
greater experience with the Payors, there can be no assurance that this will be
the case. (See "Risk Factors--Dependence on Managed Care".) Because of the
Company's limited operating history, the limited period in which it has been
assisting and managing Network Physicians, its limited experience with full and
shared-risk capitated arrangements and the effects of the acquisitions, the
Company does not believe that the period to period comparisons, percentage
relationships within periods and apparent trends set forth below are necessarily
indicative of future operations.

</TABLE>
 
     YEAR ENDED JUNE 30, 1996 COMPARED TO THE PERIOD ENDED JUNE 30, 1995.
 
     The period ended June 30, 1995 and the year ended June 30, 1996 are not
comparable periods as the period ended June 30, 1995 represents only
approximately four months of operations. Therefore, a comparison of increases
from one period to another generally is not meaningful.
 
     TOTAL REVENUES. The Company's total revenues increased to $6,117,629 for
the year ended June 30, 1996 from $850,665 for the period ended June 30, 1995.
Capitation revenue increased to $689,068 ($382,068 Global Capitation and
$307,000 Gatekeeper Capitation) or 11.3% of total revenue from $0 over the prior
period. This increase in capitation revenue during the year ended June 30, 1996
is primarily attributable to an increase in the number of Network Physicians
from 24 to 88, the increase in the number of Network Physicians participating in
Global Capitated Contracts from 0 to 45, the increase in the number of Global
Capitated Contracts from 0 to 3 and the increase in the number of Gatekeeper
Capitation Contracts from 0 to 10.
 
     MEDICAL SERVICES EXPENSE. Medical services expense was $969,677 or 15.8% of
total revenue for the year ended June 30, 1996 compared to $0 of total revenue
for the period ended June 30, 1995. This increase resulted from the increase in
the number of Network Physicians participating in Global Capitated Contracts
from 0 to 45, the increase in the number of Global Capitated Contracts from 0 to
3 and the increase in the number of Gatekeeper Capitation Contracts from 0 to
10. The Company expects these expenses to increase as the number of Network
Physicians participating in and the number of patients enrolled in benefit plans
under Global Capitated Contracts with the Company grows.
 
     CARE CENTER COSTS. Care center costs were $5,287,348 or 86.5% of total
revenue for the year ended June 30, 1996 compared to $776,865 or 91.3% of total
revenue for the period ended June 30, 1995. This increase in dollar amount
resulted from the increases in the number of Network Physicians from 24 to 88.
While these expenses are expected to increase as the Company continues adding
Network Physicians, the Company expects that these expenses will decline as a
percentage of total revenue.
 
     GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
were $6,082,902 or 99.4% of total revenue for the year ended June 30, 1996
compared to $1,877,735 or 220.7% of total revenue for the period ended June 30,
1995. This increase in dollar amount resulted primarily from increased
compensation expenses from expansion of the Company's corporate management team,
as well as its marketing, acquisitions, network development and care management
departments and additional costs incurred in adding physicians to the Company's
networks and attracting patients who enroll in benefit plans under Global
Capitated Contracts. While these expenses are expected to increase as the
Company adds Network Physicians, the Company expects that these expenses will
decline as a percentage of total revenues.
 
     DEPRECIATION AND AMORTIZATION EXPENSES. Depreciation and amortization
expenses were $435,573 or 7.1% of total revenue for the year ended June 30, 1996
compared to $27,508 or 3.3% of total revenue for the period ended June 30, 1995.
These increases resulted primarily from intangibles acquired in connection with
the purchase of certain medical practice assets from Equity Physicians, as well
as purchasing certain fixed asset additions. While these expenses are expected
to
 
                                       22
 
<PAGE>
increase as the Company continues adding Equity Physicians to the affiliated
Core Medical Groups, the Company expects that these expenses will decline as a
percentage of total revenue.
 
     INTEREST AND OTHER INCOME. Interest and other income was $272,666 or 4.5%
of total revenue for the year ended June 30, 1996 compared to $99,673 or 11.7%
of total revenue for the period ended June 30, 1995.
 
     INTEREST EXPENSE. Interest expense was $226,908 or 3.7% of total revenue
for the year ended June 30, 1996 compared to $23,915 or 2.8% of total revenue
for the period ended June 30, 1995. These increases resulted primarily from the
increase in the level of borrowings.
 
     INCOME TAX EXPENSE. In light of the Company's loss and its allowance for
deferred tax assets, for the year ended June 30, 1996 and the period ended June
30, 1995, the Company did not require a provision for income taxes.
 
     NET LOSS. The Company had a net loss of $6,612,113 for the year ended June
30, 1996 compared to $1,755,685 for the period ended June 30, 1995.
 
     LOSS APPLICABLE TO COMMON STOCK. The Company's net loss is increased by
dividends payable to the Redeemable Convertible Preferred Stockholders. The net
loss applicable to common stock was $7,164,644 for the year ended June 30, 1996
compared to $1,868,985 for the period ended June 30, 1995.
 
     THREE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO THREE MONTHS ENDED
SEPTEMBER 30, 1995.
 
     TOTAL REVENUES. The Company's total revenues increased to $3,462,124 for
the three months ended September 30, 1996 from $557,067 for the three months
ended September 30, 1995. This trend was attributable to the increase in net
revenue to $2,194,511 or 63.4% of total revenue from $557,067 or 100% of total
revenue and the increase in capitation revenue to $1,267,613 ($926,613 Global
Capitation and $341,000 Gatekeeper Capitation) or 36.6% of total revenue from $0
over the prior year. This increase resulted primarily from the increase in the
number of Network Physicians from 28 to 114, the increase in the number of
Network Physicians participating in Global Capitated Contracts from 0 to 45, the
increase in the number of Global Capitated Contracts from 0 to 3 over the prior
comparable period and the increase in the number of Gatekeeper Capitation
Contracts from 0 to 12 over the prior comparable period.
 
     MEDICAL SERVICES EXPENSE. Medical services expense was $1,195,501 or 34.5%
of net revenue for the three months ended September 30, 1996 compared to $0 or
0% of net revenue for the three months ended September 30, 1995. These increases
resulted from the increase in the number of Network Physicians participating in
Global Capitated Contracts from 0 to 45, the increase in the number of Global
Capitated Contracts from 0 to 3 over the prior comparable period and the
increase in the number of Gatekeeper Capitation Contracts from 0 to 12 over the
prior comparable period. The Company expects these expenses to increase as the
number of Network PCPs participating in and the number of patients enrolled in
benefit plans under Global Capitated Contracts with the Company grows.
 
     CARE CENTER COSTS. Care center costs were $2,103,519 or 60.8% of total
revenue for the three months ended September 30, 1996 compared to $486,251 or
87.4% of total revenue for the three months ended September 30, 1995. These
increases resulted from the increases in the number of Network Physicians from
28 to 114.
 
     GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
were $2,670,080 or 77.1% of total revenue for the three months ended September
30, 1996 compared to $536,115 or 96.2% of net revenue for the three months ended
September 30, 1995. These increases resulted primarily from increased
compensation expenses from development of the Company's corporate management
team, as well as the formation of its marketing, acquisitions, network
development and care management functions and additional organizational costs
from developing physician networks.
 
     DEPRECIATION AND AMORTIZATION EXPENSES. Depreciation and amortization
expenses were $224,384 or 6.5% of total revenue for the three months ended
September 30, 1996 compared to $50,545 or 9.0% of total revenue for the three
months ended September 30, 1995. These increases resulted primarily from
intangibles acquired in connection with the purchase of certain medical practice
assets from Equity Physicians, as well as purchasing certain fixed assets.
 
     INTEREST AND OTHER INCOME. Interest and other income was $69,038 or 2.0% of
total revenue for the three months ended September 30, 1996 compared to $71,805
or 12.9% of total revenue for the three months ended September 30, 1995.
 
     INTEREST EXPENSE. Interest expense was $148,215 or 4.3% of total revenue
for the three months ended September 30, 1996 compared to $35,111 or 6.3% of
total revenue for the three months ended September 30, 1995. These increases
resulted primarily from the increase in the level of borrowings.

     INCOME TAX EXPENSE. In light of the Company's loss and its allowance for
deferred tax assets, for the three months ended September 30, 1996 and the three
months ended September 30, 1995, the Company did not require a provision for
income taxes.
 
     NET LOSS. The Company had a net loss of $2,810,537 for the three months
ended September 30, 1996 compared to $479,150 for the three months ended
September 30, 1995.
 
     LOSS APPLICABLE TO COMMON STOCK. The Company's net loss is increased by
dividends payable to the Redeemable Convertible Preferred Stockholders. The net
loss applicable to common stock was $3,033,561 for the three months ended
September 30, 1996 compared to $560,400 for the three months ended September 30,
1995.
 
LIQUIDITY, CASH FLOW AND CAPITAL RESOURCES
 
     OVERVIEW. The Company requires capital primarily to acquire certain medical
practices from Equity Physicians, to develop and install information systems for
care management functions (necessary for the management of provider risk-sharing
contracts), for billing and collection services and to meet working capital
requirements to cover operating expenses. Through September 30, 1996, the
Company had met its cash requirements primarily through private placements of
preferred stock and through bank borrowings. As of June 30, September 30 and
November 30, 1996, the Company had cash and cash equivalents of approximately
$1,419,295, $6,620,516 and $4,081,882, respectively.
 
     Capitation arrangements generally have a favorable impact on cash flow
because the Company receives capitation revenue prior to incurring costs
associated with services provided under those contracts. Certain risk pool
arrangements negatively impact cash flow because certain medical service
expenses in connection with these arrangements are not finalized and settled by
the Company until significantly after it has received payment for the services.
 
     LIQUIDITY. At June 30, September 30 and November 30, 1996, the Company had
working capital and available credit facilities of approximately $1,409,887,
$6,588,089 and $3,806,709, respectively.
 
     CASH FLOW. Net cash used in operating activities was $5,057,464 for the
year ended June 30, 1996 compared to $1,292,824 for the period ended June 30,
1995. The use of cash for operating activities resulted primarily from (i)
$6,612,113 in net losses, (ii) a $854,283 increase in accounts receivable offset
by (iii) a $2,340,798 increase in accrued and other liabilities. Net cash used
in operating activities was $2,787,296 for the three months ended September 30,
1996.
 
     Net cash used in investing activities was $2,044,842 for the year ended
June 30, 1996 compared to $410,489 for the period ended June 30, 1995. The
Company used $2,129,464 and $238,926 of cash for the acquisition of certain
assets of medical practices and other fixed assets during the year ended June
30, 1996 and the period ended June 30, 1995, respectively. Net cash used in
investing activities was $490,876 for the three months ended September 30, 1996.
 
     Net cash provided by financing activities was $8,389,716 for the year ended
June 30, 1996 compared to $1,835,198 for the period ended June 30, 1995. (See
"--Capital Resources".) Net cash provided by financing activities was $8,479,393
for the three months ended September 30, 1996.
 
     CAPITAL EXPENDITURES. The Company has entered into binding letters of
intent for the acquisition of certain assets of medical practices which, if
completed, would require approximately $750,000 in cash and has not committed to
any material additional capital expenditures. Management intends to finance
these expenditures from available capital sources. If additional capital sources
are secured, the Company intends to acquire additional assets of medical
practices as well as incur certain additional liabilities (See "--Subsequent
Events").
 
     CAPITAL RESOURCES. On February 24, 1995, the Company issued 1,000,000
shares of Series A Preferred Stock to St. Joseph's Medical Center, Inc. (the
"Series A Preferred Stockholder") in exchange for $2,000,000 in cash and
$3,000,000 in a note (the "Series A Note"). The proceeds from this initial
issuance were used to fund the formation of the Company and for the acquisition
of certain medical assets from medical practices of certain Equity Physicians,
the incurrence of corporate expenses and the development of infrastructure in
conjunction with the Company's business strategy.
 
     On September 27, 1995, the Company received $500,000 in cash payments on
the Series A Note from the Series A Preferred Stockholder. These proceeds were
used to fund corporate expenses and the continuing development of the Company's
infrastructure.
 
     On December 1, 1995, the Company issued 355,556 shares of Series B
Preferred Stock to Med-Lantic Management Services, Inc. ("the Series B Preferred
Stockholder") in exchange for $4,000,000 in cash and entered into an agreement
("the NationsBank Credit Facility Agreement") with NationsBank of Maryland, N.A.
("NationsBank") as agent, which provides a
 
                                       24
 
<PAGE>
revolving bank credit facility ("the NationsBank Credit Facility") with a
maximum availability of $4,000,000. Advances under the NationsBank Credit
Facility bear interest at the Company's option at either NationsBank prime rate
or the Eurodollar rate plus 0.75%. The NationsBank Credit Facility expires on
December 31, 1997, and is renewable, at the sole discretion of NationsBank, for
two additional periods of one year each.
 
     Loans made pursuant to the NationsBank Credit Facility are guaranteed by
the Company's Series B Preferred Stockholder. In exchange for the guarantee of
the NationsBank Credit Facility, the Company issued 88,889 warrants to the
Series B Preferred Stockholder. The guarantee is collateralized by a security
interest in certain contract rights, including rights to the Company's patient
and global capitation receivables, under the PSO Agreements between the Company
and Core Medical Groups. Upon redemption of the Series B Preferred Stock in the
event of the issuance of junior preferred stock to a holder whose interest are
deemed adverse to the guarantor, the Company is required to obtain a release of
the guarantee.
 
     The proceeds from the issuance of the Series B Preferred Stock were used
for the acquisition of certain medical practices from Equity Physicians, the
incurrence of corporate expenses and the development of the Company's
infrastructure in conjunction with the Company's business strategy. The proceeds
from the NationsBank Credit Facility were used for the acquisition of certain
medical practices from Equity Physicians, the funding of operating expenses and
the funding of capital expenditures. At June 30, 1996, September 30, 1996 and
November 30, 1996 approximately $3,400,000, $3,600,000 and $3,600,000,
respectively, were outstanding under the NationsBank Credit Facility.
 
     On June 25, 1996, the Company received $1,000,000 in additional cash
payments on the Series A Note from the Series A Preferred Stockholder. These
proceeds were used to fund the incurrence of corporate expenses and the
continuing development of infrastructure in conjunction with the business
strategy.
 
     The Company may receive up to $1,500,000 in additional cash payments on the
Series A Note from the Series A Preferred Stockholder.
 
     (For a discussion of the terms of conversion of the Preferred Stock into
Class C Common Stock, see "Description of Capital Stock".)
 
     On August 15, 1996, the Company established a $1,500,000 bridge loan
facility (the "Bridge Loan Facility") with First National Bank of Maryland, N.A.
("First National"). The Bridge Loan facility was repaid on January 13, 1997. The
Company is negotiating a $10,000,000 credit facility with First National (the
"First National Credit Facility" for working capital and other general corporate
purposes). Although there can be no assurances the Company will obtain the First
National Credit Facility, the Company is proceeding with the loan approval
process with the First National Bank. The inability of the Company to obtain the
First National Credit Facility could have a material adverse effect on the
Company.
 
     On September 4, 1996, the Company issued 428,571 shares of Series C
Preferred Stock to Genesis Health Ventures, Inc. (the "Series C Preferred
Stockholder"), in exchange for $7,500,000 in cash. On January 2, 1997, the
Company issued 142,857 additional shares of the Series C Preferred Stock to the
Series C Preferred Stockholder in exchange for $2,500,000 in cash. The proceeds
from these issuances (the "Initial Genesis Funding") have been and will be used
to fund corporate expenses in conjunction with the business strategy and the
acquisition of medical practices or IPA contracting rights. The Company may
issue up to 500,000 additional shares of the Series C Preferred Stock in
exchange for up to $10,000,000 in cash (the "Additional Genesis Funding") if
certain Medicare capitated milestones are achieved. There can be no assurance
that such Medicare milestones can be achieved and that the Company will receive
the Additional Genesis Funding.
 
   
     SUBSEQUENT EVENTS. The Company intends to meet its cash requirements after
June 30, 1996 through a combination of some or all of the following sources of
capital: (i) up to $10,000,000 from the proceeds of the sale of Series C
Preferred Stock, (ii) up to $10,000,000 from the establishment of the First
National Bank Facility, (iii) up to $35,000,000 from the private placement of
the Notes and Warrants, (iv) up to $20,000,000 from the private placement of one
or more new series of preferred stock, and (v) $5,000,000 from the proceeds of a
private placement of preferred stock or receipt of $5,000,000 of subordinated
debt which the Company expects to close prior to January 31, 1997. The Company's
ability to consummate the First National Credit Facility or the Notes and
Warrants is subject to the consent of the holders of the Series A, Series B and
Series C Preferred Stock under certain circumstances. (See "Risk
Factors--Liquidity: Restrictions on Financing".) Although the terms of the Notes
have not been determined, the Notes are expected to (i) carry an interest rate
from 11% to 15%, (ii) mature in seven years and (iii) include redemption
provisions permitting the Company to redeem the Notes under certain
circumstances. The Notes would include covenants that limit the Company's
ability to incur indebtedness senior to the Notes, but would permit the issuance
of up to $15 million in senior secured debt for working capital purposes. In
addition, as part of the issuance of the Notes, the Company anticipates that it
will issue warrants to purchase between 350,000 and 900,000 shares of Class A
Common Stock at an exercise price of between $15.00 and $20.00. There can be no
assurance that any of
    
 
                                       25
 
<PAGE>
the foregoing financings will be consummated or that, if consummated, that such
financings will be made on terms favorable to the Company or as described above.
The Company expects to consummate at least one of the transactions described
above pursuant to which the Company expects to receive net proceeds of at least
$10 million.
 
     Until the Company and its Payors attract an adequate number of Capitated
Lives in Global Capitated Contracts, the Company expects to incur operating
losses and experience negative operating cash flows. The Company believes that
its cash on hand at January 15, 1997, the balance remaining available under the
NationsBank Credit Facility and the $5,000,000 in additional preferred stock
outlined above, will be sufficient to meet the Company's operations through June
30, 1997. However, in the event that the Company either has not attracted an
adequate number of Capitated Lives in Global Capitated Contracts in order to
offset operating expenses, or has not secured some substantial portion of the
additional capital described above, the Company will not be able to execute its
business strategy and the Company's operating results and financial condition
could be materially and adversely affected.
 
   
     In the event that the Company is successful in obtaining the additional
capital described above, in addition to the commitments for capital expenditures
described above (see "--Capital Expenditures"), the Company intends to expend
capital on improving information systems, expanding corporate infrastructure,
and to acquiring medical practices. There can be no assurance that the Company
will be able to establish a First National Credit Facility, consummate an
offering of Notes, close the additional issuance of Series C Preferred Stock
pursuant to the Additional Genesis Funding, consummate an offering of Series D
Preferred Stock, or close the $5,000,000 private placement of preferred stock or
receipt of $5,000,000 in subordinated debt on terms favorable or acceptable to
the Company. The inability of the Company to obtain such funding, either in
whole or part, would impair the Company's ability to make intended capital
expenditures and to execute its planned strategy and therefore could have a
material adverse effect on the Company's results of operations and financial
condition.
    
 
     The Company expects that it will require significant additional capital to
fund additional expenses (primarily acquisition of medical practices and
expenses of corporate infrastructure) for the foreseeable future, and expects to
seek additional financing of debt and/or equity. The amount of such additional
capital will depend to a large degree on the rate of the Company's expansion and
the types of transactions with physicians, and, thus, cannot be predicted with
certainty.
 
FACTORS THAT MAY AFFECT FUTURE RESULTS
 
     The future operating results and financial condition of the Company could
be materially and adversely affected by a number of factors such as risks
relating to the Company's growth strategy including competition for expansion
opportunities, integration risks, dependence on HMO Enrollee growth and the
ability to raise the capital required to support growth; the capitated nature of
revenues and control of health care costs; exposure to professional liability;
health care reform and government regulation; and the Company's ability to sell
its services profitably, successfully increase market share and manage expense
growth relative to revenue growth. See "Risk Factors."
 
                                    BUSINESS
 
INDUSTRY
 
     HCFA estimates that 1995 national health spending was approximately one
trillion dollars. The Company believes that physicians control more than 80% of
overall expenditures. Physicians have traditionally provided medical care on a
fee-for-service basis, which provides few incentives for the efficient
utilization of resources and has contributed to increases in health care costs
that are significantly higher than historical inflation rates. Concerns over the
accelerating cost of health care have resulted in the increasing prominence of
managed care, and employers, individuals and the government have increasingly
turned to HMOs and other forms of managed care in an attempt to manage health
care costs more effectively. According to industry sources, the number of
individuals enrolled in HMOs grew from 15 million Enrollees in 1984 to over 50
million in 1996, an 11% compound annual growth rate. According to the United
States General Accounting Office, there are approximately 600 HMOs currently
operating in the United States, covering approximately 20% of the U.S.
population. Moreover, Federal and State governments are increasingly using HMOs
to cover health benefits under Medicare and Medicaid programs. The Company
believes that overall enrollment in HMOs will continue to increase due to the
fact that HMOs generally offer lower overall premium costs than traditional
fee-for-service indemnity health insurance.
 
     Health care in the United States historically has been delivered through a
fragmented system of health care providers, including individual or small groups
of PCPs and specialists. According to the American Medical Association, there
are approximately 565,000 active physicians in the United States, with
approximately 70% of these physicians, or 397,000, practicing individually or in
a two person group. HCFA estimates that the physician services market is $200
billion.
 
                                       26
 
<PAGE>
     In an effort to manage their costs and minimize their risk, HMOs are
shifting from fee-for-service payments for physicians and are increasingly
utilizing "capitation" arrangements. Under capitation arrangements, physicians
receive a fixed monthly fee per assigned enrollee, and in return provide all
services required by such Enrollee in specified areas. Under these arrangements,
physicians assume the risk that they will be able to provide medical care at
costs less than the capitation payment. The Company believes that traditional
PCP and small group specialty practices are at a disadvantage in a managed care
environment because they typically have high operating costs, little bargaining
power with HMOs and other Payors and little or no information or data regarding
utilization or the total health care costs of treating their patients, and
therefore are unable to assess the business risks of managed care. In addition,
these physician practices almost always have insufficient capital to purchase
new technologies and lack the sophisticated systems necessary to track patient
data and performance and to contract effectively with HMOs and other managed
care entities. As a result, the Company believes PCPs and specialist physicians
are increasingly abandoning traditional practices in favor of affiliating with
larger organizations, such as the Company.
 
     Traditionally, the primary care or "general practice" physician has enjoyed
broad patient loyalty and continuity and has been the point of entry into the
health care system for many patients, including those who require the services
of a specialist physician. The traditional role of the PCP has been to refer the
patient to a specialist physician who is typically not affiliated with the PCP
in the practice of medicine. Fee-for-service reimbursement to, and therefore
compensation levels for, specialist physicians have significantly exceeded the
compensation levels for PCPs. The result is that, under a traditional fee-for-
service environment, the PCP largely controls the amount of care their patients
receive without any information about the cost or efficacy of the care or
sharing in any of the revenues generated by that care.
 
     The Company believes that its strategy of establishing and consolidating
Core Medical Groups, IPAs and related networks based upon PCPs, and entering
into arrangements with specialist networks, to compete in the managed care
marketplace will result in significant revenues from capitated contracts with
HMOs and other Payors to pay for flexible managed care of patients.
 
STRATEGY
 
     The Company's strategy is based upon the concept that recent changes in the
health care industry have created an opportunity to establish physician provider
groups and IPAs that can provide a broad range of medical services to patients
and prepaid Managed Care members, more efficiently and profitably than is
possible under the traditional "fee-for-service" or "HMO network" models. The
Company believes that the development of an integrated health care delivery
system will allow it to negotiate Global Capitated Contracts with HMOs and other
Payors that will enable the Company to reduce administrative costs and derive
revenues by encouraging preventive medicine and by the appropriate utilization
of medical resources. The key elements of this strategy are as follows:
 
     INTEGRATING HEALTH CARE PROVIDERS INTO COMPREHENSIVE NETWORKS. The Company
consolidates individual or groups of PCPs, specialists, hospitals and other
providers in the Baltimore and Washington metropolitan areas and surrounding
regions into primary care-driven comprehensive health care networks, permitting
the Company to assume full risk under contracts with Managed Care Plans for
certain health care services. Physicians will enter employment, IPA, joint
venture or other contractual relationships with the Company, while the Company
will negotiate favorable rates, to the extent feasible, from hospitals and other
providers of medical services. All participants must agree to follow the
Company's PCP-driven clinical protocols and procedures, unless they determine it
is medically inappropriate to do so, and are closely supervised by the PCPs. The
Company believes that its health care delivery networks (i) provide physicians
with greater access to managed care contracts by facilitating contractual
relationships with multiple HMOs or other Payors, (ii) establish a single point
of entry into an integrated health care delivery network for HMOs and other
Payors, and (iii) offer patients a comprehensive range of high quality medical
care. The Company's development of its health care network is currently focused
on the Baltimore and Washington metropolitan area and surrounding areas. After
the establishment of its network in this market, the Company may expand outside
of this region.
 
     ATTRACTIVE TO PHYSICIANS. The Company seeks to be attractive to physicians,
and particularly to PCPs. The Company is dedicated to the creation of
professionally managed networks that grant physicians clinical autonomy and the
ability to practice medicine using clinical protocols and procedures developed
in cooperation with fellow physicians and other sources. 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. A key component of the Company's strategy is the ability of
the Core Medical Groups and IPAs to retain
 
                                       27
 
<PAGE>
broad clinical autonomy over the manner in which physicians conduct the practice
of medicine. As a result of this strategy, the Company owns no equity interest
in the Core Medical Groups.
 
     While the Company provides clinical protocols and procedures, Network
Physicians are always free to diverge from such protocols when they determine
that it is medically appropriate to do so. The Company's contracts with
physicians and other health care providers expressly state that the Company
shall not interfere with the physician's relationship with and responsibility to
the patient. The Company does not believe that the development and dissemination
of clinical protocols and quality assurance programs that may assist the
physician in providing cost effective and high quality medical care does not
make the Company or any other entity which provides quality assurance a health
care provider. Each Network Physician remains free and has the duty under all of
the Company's contracts to treat his or her patient as they determine necessary,
and not to discriminate against patients covered by the Company's managed care
plans. Further, the Company does not include in any of its contracts financial
penalties for physicians who choose not to follow any guidelines or who refer
patients without complying with the Company's reasonable notification
requirements.
 
     FOCUS ON MANAGED CARE. The Company designs its physician-driven health care
delivery networks to meet the needs of HMOs, other Payors and patients, to
identify and recruit primary and specialty care physicians, hospitals and other
providers and to integrate such providers into networks that provide coordinated
medical coverage to such Payors' Enrollees. The Company seeks to benefit from
the desire of Payors and employers to reduce health care costs and risks, and
the trend toward prepaid managed health care. Rather than entering into an
exclusive arrangement with any single Payor, the Company seeks contracts with a
risk sharing arrangement, including Global Capitated Contracts, with each of the
HMO Payors in a region in which Network Physicians and other physicians operate
their medical practices. Because the Company's networks are PCP-driven and
patient-PCP relationships are typically strong, the Company expects that the
relatively large, pre-existing patient base of such PCP practices will be
attractive to Payors. The Company believes that its emphasis on wellness network
structure and management techniques (including the collection of meaningful
data, information systems, care utilization and quality management systems,
referral procedures, risk management programs, assistance with physician
credentialing and contracting with Payors) will enable it to effectively contain
costs and negotiate favorable capitation and shared risk arrangements.
 
     MEDICARE MANAGED CARE. An important component of the Company's strategy is
the enrollment of Medicare-eligible persons in the Medicare managed care plans
with which the Company contracts. Reimbursement rates for Medicare patients are
considerably higher than for non-Medicare patients, reflecting the greater
historical expense of providing care to Medicare patients. HCFA estimates that
as of 1995 there were approximately 613,000 Medicare recipients in Maryland,
including over 300,000 in the greater Baltimore area, and that, as of September
1996, only approximately 39,000 were enrolled in HMOs in the state of Maryland.
The Company's results of operations are highly dependent on its ability to
convert its present portion of Network Physicians' current Medicare
fee-for-service patients to Medicare managed care plans and attract new Medicare
patients that enroll in Medicare HMOs with whom the Company contracts.
 
     The Company currently has a Medicare Global Capitated Contract with Health
Care Corporation of the Mid-Atlantic and a Medicare Global Capitated Contract
with Chesapeake Health Plan under which the Company receives capitation payments
on a per member per month basis for each subscriber who participates in one of
the plans and is enrolled with a Network Physician. For the Medicare patients
enrolled in the plans contracting with a Network Physician, the Company receives
capitation payment revenue, assumes the risk of the cost of providing care to
the patients, and seeks to earn revenues by encouraging preventative medicine,
high quality care and appropriate utilization of medical resources.
 
     EFFECTIVELY MANAGE THE DELIVERY OF MEDICAL CARE. The Company seeks to
deliver quality medical care while controlling costs and ensuring patient
satisfaction. Accordingly, the Company seeks qualified physicians and
coordinates the provision of health care services among the physicians,
hospitals, and other providers within its networks. The Company seeks (i) to
change the focus of health care utilization to foster health promotion at the
PCP and care manager level, (ii) to reduce specialist and other provider costs
through early and aggressive intervention by affiliation with fewer specialists
who will benefit from increased Managed Care activities at lower reimbursement
rates, and (iii) to reduce hospital, particularly inpatient, costs through more
efficient utilization of lower cost components of the health care delivery
system when appropriate without sacrificing quality. In addition, the Company
will monitor the delivery of high-quality medical care through the development
and implementation of information systems tailored to managed care. The Company
believes that much of the high cost of health care is caused by the lack of
incentives in the health care system to help patients avoid high-cost, episodic
care, and excessive utilization of high cost services. The Company believes that
lower cost care, such as outpatient or home care, where appropriate, is both
preferable to the patient and less expensive to the Payor.

     EXPANSION STRATEGY. The Company must actively develop or consolidate
existing and new markets through selective acquisitions and joint ventures. The
Company develops existing markets by (i) capturing additional revenues from
existing practices as patients migrate from traditional fee-for-service plans to
capitated managed care programs, (ii) adding new physicians to existing
networks, and (iii) contracting with Payors to expand the number of capitated
lives within existing physician practices.
 
HISTORY OF THE COMPANY
 
     INITIAL TRANSACTIONS. The Company is a managed care and medical management
company which was incorporated in June 1994 and commenced operations on February
24, 1995.
 
     Baltimore Medical Group, P.A. ("BMGPA") was incorporated in January 1993
and commenced operations in May 1993 as a primary care-driven provider group
that would ultimately create enough critical mass effectively to compete in the
rapidly changing health care market. The physicians of BMGPA also planned the
formation of one or more business entities to provide the management,
administrative, contracting, recruiting and marketing services needed by the
physicians. The Company was organized as a managed care and medical management
company to provide, or cause to be provided, all of the business services that
were required by BMGPA other than the provision of medical care to patients. In
February 1995, the Company commenced operations by (i) reorganizing BMGPA and
facilitating the transfer of its laboratory assets to Baltimore Medical Group,
LLC, the Company's first Core Medical Group, (ii) assuming exclusive management
responsibility and control over the practice assets and employees of the 15
BMGPA physicians, and (iii) issuing Class B Common Stock of the Company to a
partnership owned primarily by the 15 BMGPA physicians. Scott Rifkin, M.D., Alan
Kimmel, M.D., J. David Nagel, M.D., Peter LoPresti, D.O. and Robert Ancona,
M.D., five of the original members of Baltimore Medical Group, LLC, are
currently directors of the Company.
 
     The Company received the BMGPA physicians' assets in a reorganization
through Medical Holdings Limited Partnership, a Maryland limited partnership
("MHLP"), a stockholder of the Company. In February 1995, at the time of the
establishment of Baltimore Medical Group, LLC, MHLP was formed and BMGPA
physicians transferred certain assets of their medical practices, excluding
laboratory and other ancillary assets, to MHLP in exchange for an aggregate
consideration of approximately $467,000, consisting of (i) limited partnership
interests in MHLP that are currently equal to approximately a 22.5% interest in
MHLP, (ii) approximately $19,000 in cash, and (iii) promissory notes with an
aggregate face value of approximately $443,000. In order to comply with
applicable regulatory requirements, the laboratory and other ancillary assets
were transferred directly to Baltimore Medical Group, LLC by BMGPA. MHLP
simultaneously conveyed substantially all of its remaining assets to the
Company, and the Company issued to MHLP 1,100,000 shares of the Company's Class
B Common Stock. As a result of a subsequent stock split, MHLP now holds
2,200,000 shares of the Company's Class B Common Stock. The physician owners of
BMGPA became members and employees of Baltimore Medical Group, LLC, and have
continued the practice of medicine through Baltimore Medical Group, LLC. The
Company and Baltimore Medical Group, LLC entered into a PSO Agreement pursuant
to which the Company provides Managed Care contracting and practice management
services to Baltimore Medical Group, LLC, leases to Baltimore Medical Group,
LLC, the assets used by the physicians in their medical practices, and provides
non-medical employees to Baltimore Medical Group, LLC. See "Development of
Integrated Health Care Delivery System--Focus on Primary Care Physicians."
 
     Under the Partnership Agreement and other documents related to MHLP, shares
of the Company's Class B Common Stock held by MHLP will be distributed to the
partners of MHLP upon a change in control of the Company, including an
underwritten public offering, or other event of liquidation of MHLP. The General
Partner of MHLP is BMGGP, Inc., a Maryland corporation, which owns a one percent
(1%) interest in MHLP. The stockholders of BMGGP, Inc., are 17 of the initial
members of Baltimore Medical Group, LLC, and the 17 initial limited partners of
MHLP, including Drs. Rifkin, Kimmel, Nagel, LoPresti and Ancona. Accordingly,
the members of Baltimore Medical Group, LLC, indirectly own shares of the Class
B Common Stock through their limited partnership interests in MHLP and, for the
initial 17 members of Baltimore Medical Group, LLC, as stockholders of BMGGP,
Inc.
 
     Since the formation of Baltimore Medical Group, LLC and MHLP, additional
physicians have sold 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, Cumberland Valley Medical Group,
LLC, Doctors Health Montgomery, LLC, or Anne Arundel Medical Group, LLC. In
addition, such Equity Physicians have become employees of one of these Core
Medical Groups. In some instances, Equity Physicians received shares of the
Company's Class B Common Stock directly in lieu of partnership interests in
MHLP. The equity interests of all Core Medical Groups are owned exclusively by
member Equity Physicians, who have broad autonomy and control over clinical
matters. Following the reorganization of BMGPA in
 
                                       29
 
<PAGE>
February 1995, the Company acquired five practices during fiscal year 1995 for
an aggregate consideration of approximately $184,000, consisting of (i) limited
partnership interests in MHLP that are currently equal to approximately a 6%
interest in MHLP (equivalent to 132,000 shares of the Company's Class B Common
Stock, valued at $.01 per share), (ii) approximately $16,000 in cash, and (iii)
promissory notes with an aggregate face value of approximately $167,000. During
fiscal year 1996, the Company acquired 29 additional practices for which
physicians received an aggregate consideration of approximately $3,867,000,
consisting of (i) limited partnership interests in MHLP that are currently equal
to approximately a 31% interest in MHLP (equivalent to 683,000 shares of the
Company's Class B Common Stock, 231,000 of which were valued at $.01 per share
and 452,000 of which were valued at $3.00 per share), (ii) 198,000 shares of the
Company's Class B Common Stock (valued at $3.00 per share), (iii) approximately
$290,000 in cash, and (iv) promissory notes with an aggregate face value of
approximately $1,625,000. During fiscal year 1997 through January 10, 1997, the
Company acquired certain assets of 22 additional practices for which physicians
received an aggregate consideration of approximately $3,222,000, consisting of
(i) limited partnership interests in MHLP that are currently equal to
approximately a 4.7% interest in MHLP (equivalent to 102,429 shares of the
Company's Class B Common Stock, valued at $7.00 per share), (ii) 195,000 shares
of the Company's Class B Common Stock (valued at $7.00 per share), (iii)
approximately $590,000 in cash, and (iv) deferred consideration aggregating
approximately $550,000.

     The Company is constructing its Integrated Health Care Delivery System
throughout the Baltimore-Washington metropolitan area and contiguous regions by
acquiring certain medical practice assets, obtaining the right to negotiate and
execute managed care contracts for individual physicians and medical groups.
 
     EXPANSION INTO CARROLL COUNTY, MARYLAND. In November 1995, the Company
acquired certain assets of the practices of five primary care physicians and
formed Carroll Medical Group, LLC ("Carroll Medical Group") located in Carroll
County, Maryland. Like the majority of the Baltimore Medical Group, LLC
physicians, these doctors acquired cash and limited partnership interests in
MHLP and became members of and employed by Carroll Medical Group. Carroll
Medical Group entered into a PSO Agreement with the Company on terms
substantially identical to the Baltimore Medical Group, LLC PSO Agreement. In
September 1996, an additional physician joined Carroll Medical Group.
 
     EXPANSION INTO MONTGOMERY COUNTY, MARYLAND. In February 1996, the Company
entered into binding letters of intent to acquire the primary care practices of
21 physicians in Montgomery County, Maryland. The Company has consummated
transactions involving nineteen physicians and formed Doctors Health Montgomery,
LLC ("Doctors Health Montgomery"). The Company expects to consummate the
remaining transactions by March 31, 1997. Doctors Health Montgomery entered into
a PSO Agreement with the Company in September 1996.
 
     EXPANSION INTO ANNE ARUNDEL COUNTY, MARYLAND. In February 1996, the Company
entered into binding letters of intent to acquire certain assets of primary care
practices of nine physicians in Anne Arundel County, Maryland. The Company
consummated transactions involving one primary care practice consisting of six
of such physicians in December 1996 and entered into a PSO Agreement with Anne
Arundel Medical Group. The Company expects to complete the acquisition of
primary care practices involving three physicians in the first calendar quarter
of 1997.
 
     EXPANSION INTO ALLEGANY COUNTY, MARYLAND. In May 1996, the Company
consummated the acquisition of five primary care physician practices located in
Cumberland, Maryland, which on May 1, 1996, formed the Cumberland Valley Medical
Group ("CVMG"). Like Carroll Medical Group and Doctors Health Montgomery, CVMG
entered into a PSO Agreement with the Company on terms substantially identical
to the Baltimore Medical Group, LLC PSO Agreement. The Company is establishing
an IPA in Allegany County.
 
     EXPANSION INTO WASHINGTON COUNTY, MARYLAND. The Company has established an
exclusive Managed Care contracting arrangement with Quality Health Care IPA
("QHC"), an IPA representing approximately 21 primary care physicians in
Washington County, Maryland. Thirteen of the 21 physicians have agreed to
conduct all managed care contracting through the Company and QHC on an exclusive
basis. Pursuant to the IPA agreement, the Company is the exclusive Managed Care
contracting entity on behalf of the IPA's PCPs, and is developing a network of
specialists.
 
     EXPANSION INTO HARFORD COUNTY, MARYLAND. The Company has established a
Managed Care contracting arrangement with a group of 11 primary care physicians
in Harford County, Maryland. Pursuant to the IPA Agreement, the Company is the
exclusive Managed Care contracting entity for Medicare managed care patients of
this IPA.
 
     EXPANSION INTO NORTHERN VIRGINIA. The Company has entered into a merger
agreement and a management services agreement with Medtrust Medical Group, Inc.,
a non-stock membership organization based in Springfield, Virginia. Pursuant to
the merger agreement, the IPA will be merged into a subsidiary of the Company
and the members of the IPA will receive consideration in the form of cash and
shares of the Class B Common Stock. Completion of the merger and related
transactions are expected to result in the creation of a Core Medical Group and
Exclusive IPA consisting of primary care physicians providing medical care
throughout northern Virginia and a network of specialist physicians. As of
January 10, 1997, Medtrust had approximately 123 PCP and 313 specialist
participating physicians. Thirty-three of the PCPs have executed exclusive
participation agreements with the Company and have indicated an interest in
joining a Core Medical Group or conducting managed care contracting solely
through the Company. Completion of the merger is subject to conditions,
including but not limited to the agreement that at least 30 of the physicians
must execute three-year exclusive managed care contracting agreements with the
Company, Medtrust's members must approve the merger, compliance with Virginia
blue sky laws, and no more than 20% of Medtrust's members shall have dissented
to the consummation of the merger. The Company believes the merger will be
completed before March 31, 1997.
 
     The Company also entered into a network contracting and management services
agreement with the IPA, pursuant to which the Company will pay certain operating
expenses of Medtrust and Medtrust has designated the Company as the exclusive
managed care contracting entity for the IPA.
 
     JOINT CONTRACTING ARRANGEMENTS IN BALTIMORE. The Company has entered into a
Contracting and Managed Care Services Agreement with an organization which
operates health care facilities in Baltimore City and employs and contracts with
 
                                       32
 
<PAGE>
approximately 37 physicians in Maryland. Under the arrangement, the Company acts
as the organization's exclusive contracting entity for Medicare managed care
contracts. Under the arrangement, the Company pays to the organization the
primary care and specialty care portion of the global capitation revenue
received by the Company for the organization's Enrollees. The remaining portion
of the Global Capitation Revenue related to other medical services (primarily
hospitalization) provided to the organization's Enrollees is managed by the
Company in a "risk pool" and the difference between the actual expenses incurred
by the Enrollees and the global capitation funded to the "risk pool" is divided
between the Company and the organization pursuant to the Contracting and Managed
Care Services Agreement.
 
     FORMATION OF CARDIOLOGY DEPARTMENT. The Company has entered into a
non-binding letter of intent with the Board of Directors of a cardiology
practice, providing services to patients in the Baltimore metropolitan area, to
acquire certain practice assets pursuant to a merger and other transactions. The
letter of intent contemplates that the practice would receive 120,000 shares of
Class B Common Stock, cash in the amount of $50,000, and deferred compensation
based upon the practice's accounts receivable and the practice would be
integrated into Baltimore Medical Group as a department dedicated to cardiology
(the "Cardiology Department"). The Company intends to acquire additional
specialists and create either stand-alone Core Medical Groups or integrate such
acquired specialists into existing Core Medical Groups.
 
     The Company expects it will continue to expand by increasing the number of
physicians in each Core Medical Group, forming new Core Medical Groups, entering
into Non-Exclusive and Exclusive IPA Agreements with physicians and pursuing
acquisition and expansion opportunities in the Baltimore and Washington
metropolitan area and surrounding regions.
 
OVERVIEW OF BUSINESS ACTIVITIES
 
     The Company is a managed care and medical management company. The Company
is engaged in its activities through its Integrated Health Care Delivery
Network. The Company's ability to generate earnings is significantly predicated
upon its ability to arrange for the delivery of health care services for which
it contracts at a cost which is less than the fixed fees which it receives under
its Global Capitated Contracts. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--General--Source of Revenue and
Earnings."
 
     As a managed care company, the Company negotiates and enters into a variety
of risk-sharing arrangements with HMOs and other Payors, including Global
Capitated Contracts (and sub-capitation contracts) pursuant to which (i) such
Payors pay the Company a fixed amount per Enrollee per month and the Company is
responsible for meeting all of the primary and specialty care, hospital and
certain other related health care needs (or specified portions thereof) of such
Enrollee and (ii) the Company pays PCPs and specialists, hospitals and other
providers within its network, or those having other contractual arrangements
with the Company for providing the required medical care. The Company, not the
Core Medical Groups, is the party to the Global Capitated Contracts and
therefore is the recipient of the capitation payments. The Company receives fee-
for-service revenues arising from the Core Medical Group's medical practices
pursuant to certain assignment provisions of the PSO Agreements. The ability of
the Company to achieve and maintain profitability will depend to a great degree
on (i) reducing the incidence of high cost acute care episodes, primarily
through wellness, prevention initiatives and aggressive care management, and
(ii) negotiating compensation arrangements that result in payments to the
Company that exceed the cost of care by the Company to PCPs, specialists,
hospitals and other providers. The Company will seek to achieve this result by
negotiating reduced fee-for-service, sub-capitation and other arrangements with
PCPs, specialists, hospitals and other health care providers, creating economic
incentives for all Network Physicians and other providers with whom the Company
contracts to utilize specialists and hospitals prudently, carefully monitoring
the quality and cost of care provided to patients, and developing programs to
promote wellness among patients. The Company has purchased insurance from
independent insurance companies which limits the amount of risk it ultimately
bears by providing reimbursements payments once medical services provided to an
individual Enrollee exceed an agreed-upon amount.
 
     The Company intends to offset most of the cost of its centralized patient
data and information systems through profits earned from managed care
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.
 
     The Company under such managed care contracts takes some of the risks of
utilization, and the risk of adverse selection by Enrollees. The Company
currently protects itself against such risks by paying for as much of the
physician services as practical through capitation (which passes on the risk to
the physicians), by obtaining stop loss insurance for high hospital and other
charges of outlier cases, by implementing and monitoring utilization review by
and among its participating Physicians, and by obtaining actuarial reviews of
the proposed capitation payments. However, there can be no assurance that the
Company will not be subject to expenses in excess of its capitated revenue. The
Company is not required to obtain an
 
                                       33
 
<PAGE>
insurance or an HMO license as long as it enters into "administrative service
provider" arrangements exclusively through HMOs under provisions of Maryland law
that expressly permit a HMO to enter into such capitation arrangements subject
to specified financial arrangements. In particular, under Maryland law, licensed
HMOs are permitted to enter into capitation arrangements with entities such as
the Company pursuant to which the Company accepts the risk of providing and
paying for the medical services required by Enrollees of an HMO. Such medical
services are provided by physicians and other providers who are independent
contractors to the Company. In connection with accepting such risk, the Company
organizes networks of physicians, provides administrative, care management
utilization review, referral management and other services necessary to accept
managed care risk. The Company complies with all required financial safeguards
under Maryland law.
 
     As a medical management company, the Company has created an Integrated
Health Care Delivery Network that includes PCPs and other physicians who
transfer certain medical practice assets to the Company and become employees of
a Core Medical Group, such as Baltimore Medical Group. PCPs may also join IPAs.
The Company also enters into network contracts with specialists who agree to
provide services to managed care patients referred by PCPs and, in certain
cases, acquires the medical practices of such specialists. The Company provides
to such Network Physicians who join Core Medical Groups certain patient care
management, managed care contracting, and administrative and financial services,
including information systems and billing services, and provides facilities,
non-physician staff personnel, equipment and other goods to the physicians for
use in their medical practices. The Company provides these medical practice
management services to certain of its Network Physicians to free the physicians
from the administrative burdens of practicing medicine and to enable them to
concentrate on providing medical care to their patients. The physicians join and
become employees of Core Medical Groups, which contract with the Company for the
provision of the medical management services. The Core Medical Groups engage
exclusively in the practice of medicine through their employed physicians and
maintain autonomy and independence over clinical matters.
 
     The Company receives fee-for-service revenues arising from the Core Medical
Group's medical practices pursuant to certain assignment provisions of the PSO
Agreements.
 
     A Network Physician who becomes employed by a Core Medical Group agrees to
conduct his medical practice only through the Core Medical Group and to permit
the Company to act as his exclusive agent for the purpose of negotiating managed
care risk and other contracts in which the PCP must participate. The Company
owns no equity or similar interest in the Core Medical Groups. The PCP's
obligation to participate in managed care contracts negotiated by the Company is
set forth in the PCP's Employment Agreement with the Core Medical Group and the
PSO Agreement between the Core Medical Group and the Company. If a PCP joins a
Company-sponsored IPA, the PCP agrees to participate in managed care contracts
negotiated and administered by the Company on either an exclusive or
non-exclusive basis.
 
     When a physician becomes an employee of one of the Company's Core Medical
Groups, the Company transitions any primary care Managed Care contracts in which
the physician participates into the Company's group contract or the applicable
Core Medical Group contract if any is in effect with respect to that Payor. If
the Company or the Core Medical Group does not have a PCP group contract in
place with the Payor and the Payor allows the contract to be assigned to the
Company, the Company will maintain the contract on the physician's behalf under
the same contract terms. The reimbursement provisions under such contracts are
on either a fee-for-service or capitated basis.
 
     Physicians participating in the Company's networks may derive benefit from
the successful implementation of the Company's strategy in several ways. A
physician to whom Securities are issued in the various affiliation transactions
described elsewhere herein will benefit through the ownership of Securities if
the Company achieves and grows in profitability. A physician, whether or not he
becomes an owner of Securities, may also receive capitated income from the
Company's managed care contracts and may also receive cash bonus payments out of
the bonus pool established by the Company for Network Physicians.
 
     As of January 10, 1997, there were 1,150 Network Physicians in six regional
networks throughout the state of Maryland and one regional network in Northern
Virginia, including approximately 310 PCPs, 84 obstetrician-gynecologists and
756 specialist physicians. Of these, approximately 89 were Equity Physicians who
had transferred, or entered into binding letters of intent or otherwise agreed
to convey, certain practice assets of their practices to the Company and become
employees of Core Medical Groups. As of such time, the networks established by
the Company were providing services in Central and Western Maryland. As
described in "Strategy--Expansion Strategy," the Company intends to enter into
selective medical practice acquisitions and other contractual arrangements that
will result in the Company operating in areas beyond those in which it currently
operates.

OPERATIONS
 
     The Company's operations to date have consisted of recruiting and acquiring
certain assets of PCP and other physician's practices, negotiating and managing
risk, capitated or fee-for-service contracts with HMOs and other Payors,
contracting with individual specialists, specialist networks and IPAs,
developing and implementing a marketing program to convert Medicare patients
from traditional fee-for-service insurance to Medicare HMO programs, and
providing billing, accounting, legal, contracting support and care management
services to its Equity Physicians and certain Network Physicians. Beginning in
February 1995 with respect to Baltimore Medical Group, December 1995 with
respect to Carroll Medical, May 1996 with respect to Cumberland Valley Medical
Group, June 1996 with respect to Quality Health Care IPA, September 1996 with
respect to the Doctors Health Montgomery Medical Group, and October 1996 with
respect to the Harford County IPA physicians, the Company has negotiated managed
care contracts with HMOs and other Payors on behalf of the PCP practices of such
medical groups. The Company also manages primary care IPAs in Central and
Western Maryland.
 
     The Company also maintains primary care and specialist contracts on behalf
of Network PCPs and certain specialists under similar or improved non-risk
contract terms. The reimbursement provisions under such contracts are on either
a fee-for-service (FFS) or capitated basis. The Company currently maintains such
contracts for certain of its PCPs and specialists with Payors including Aetna,
CIGNA, NYL Care, Health Plus, Principal Health Care 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,
Mid-Atlantic Medical Services, Inc., U.S. Health Care, USA Health Network,
Employee Health Plan and John Hancock Health Plan.
 
     To date, the Company has entered into two Medicare Global Capitation
Contracts and one commercial Global Capitation Contract with Payors and is
continuing to negotiate Global Capitation Contracts with additional Payors who
conduct business in the Baltimore and Washington metropolitan area and
surrounding regions. Under these risk contracts, the Company receives a
capitation payment and must provide Enrollees with primary care and certain
specialist and hospitalization services.
 
     In October 1995, the Company entered into a contract with Free State Health
Plan, Inc., an affiliate of Blue Cross-Blue Shield of Maryland ("Free State")
pursuant to which the Company's PCPs provide medical services to commercially
insured Enrollees on a global capitated basis (the "Free State Commercial
Contract"). In this contract, the Company assumes risk for all professional
services and shares risk with Free State on institutional services.
 
     In February 1996, the Company entered into a Global Capitated Contract with
Health Care Corporation of the Mid-Atlantic, an affiliate of Blue Cross-Blue
Shield of Maryland, ("HCCMA") pursuant to which the Company's PCPs provide
medical services to Medicare patients on a global capitated basis (the "HCCMA
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 HCCMA Medicare Contract provides that the Company
will receive a capitation payment per patient per month and pay for all medical
expenses for covered medical services based upon rates developed by the U.S.
Health Care Financing Administration ("HCFA").
 
     In May 1996, the Company entered into a Global Capitated Contract with
Chesapeake Health Plan, an affiliate of United Health Care, pursuant to which
the Company's PCPs will provide medical services to Medicare patients (the
"Chesapeake Contract"). Under the Chesapeake Contract, Chesapeake pays a
capitation payment (which may be increased based on enrollment) to the Company
on a per member per month basis based on the projected demographic distribution
of the patients enrolled with the PCPs, as well as the age, sex and Medicaid
eligibility of the subscribers enrolled with a Network PCP in Chesapeake's
Advantage 65 Medicare HMO programs. Under the contract, Chesapeake has delegated
to the Company the right to manage the utilization of medical services.
 
     As of January 10, 1997, the Company had approximately 31,000 Capitated
Lives derived from the participation of 55 of the Company's 310 Network PCPs in
the Managed Care contracts of the Company, its subsidiaries and affiliates. Of
these 31,000 capitated lives, approximately 27,100 participate in the Company's
commercial Gatekeeper Capitated contracts, approximately 2,200 participate in
commercial Global Capitated Contracts, and approximately 1,700 in Medicare
Global Capitated Contracts. The Company derives no earnings from the commercial
Gatekeeper Capitated Contracts and plans to convert the managed care lives in
commercial gatekeeper contracts to Full Risk and/or Global Capitated commercial
contracts. (See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Sources of Revenues and Earnings.") The Company believes
that there are approximately 100,000 additional Medicare subscribers who are
patients of the Company's Network PCPs. The Company's ability to derive earnings
from any of its capitated lives is affected by whether the Network Physician is
a member of a Core Medical Group or a participant in an IPA.
 
                                       35

     The Company has developed and is implementing a marketing program in
conjunction with HCCMA and Chesapeake to enroll Medicare-eligible patients in
HCCMA'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 HCCMA and Chesapeake
arrangements.
 
     The Company's operations also include the recruitment of specialists into
Core Medical Groups and/or developing a network of preferred provider
specialists who are paid on a discounted fee-for-service or subcapitated basis.
As of January 10, 1997, the Company had access to approximately 756 specialists
in its networks pursuant to direct or indirect contractual arrangements. The
Company expects that an increasing percentage of the specialist networks will
enter into contracts that provide for compensation on a capitated basis. The
Company currently has capitated payment arrangements with Womancare IPA, a
Company-owned network of 84 physicians providing obstetrical/gynecological
services, and with outside providers of radiology and laboratory services. Under
the Company's agreements with the respective specialty network, the
participating specialist providers provide services to the Company's members
referred by a Network Physician, and the network is reimbursed on a capitated
basis. The Company owns a majority interest in Womancare IPA.
 
     In addition, the Company's operations include the provision of traditional
management services to the individual medical practices of each Core Medical
Group, including administrative, legal and accounting services, lease
negotiations, and financial, billing and collection services. As of January 10,
1997, the Company has installed its information systems in 37 PCP offices to
facilitate development of a unified information system for referral management,
billing and collection activity, utilization review, and group purchasing and
risk management programs. As of January 10, 1997, the Company had assumed
responsibility for the billing operations of 35 PCP practices, representing 62
physicians, and two laboratories which provide services to two Core Medical
Groups, which employ 70 physicians.
 
     As of the date of this prospectus, the Company has not yet conducted
material operations through Doctors Health System-Medalie Equipment Corporation,
a wholly-owned subsidiary of the Company, except to transfer certain cardiology
equipment, to the subsidiary, or through Doctors Health System Primary Care IPA,
Inc., a wholly-owned subsidiary of the Company.
 
DEVELOPMENT OF INTEGRATED HEALTH CARE DELIVERY SYSTEM
 
     CONTRACTS WITH PHYSICIANS.
 
     The Company contracts with Network Physicians and other physicians in one
of several ways: (1) through the transfer of certain of their medical practice
assets and contracts to the Company, as a result of which the physician may
obtain, directly or indirectly, cash and/or an equity interest in the Company;
(2) through an Exclusive IPA arrangement, pursuant to which such physician
agrees to conduct all managed care contracting activity exclusively through the
Company and to take as patients any capitated patient referred by the Company up
to a certain level; (3) through a Non-Exclusive IPA arrangement, in which the
physician may contract with or through other IPAs but agrees to take all managed
care patients referred by the Company; or (4) a myriad of other contractual
arrangements involving an IPA, joint venture or other arrangement in which the
physician may contract with others and may also elect to accept or not any
patients referred by the Company. The Company's goal is to remain flexible and
to accommodate the needs of physicians in each local market.
 
     The Company also enters into contracts with group practice entities,
clinics and IPAs through joint venture relationships as well as the contractual
relationships described above. The use of any particular contractual arrangement
is influenced by a number of factors, including the needs of the physicians, the
type of practice in which such physicians are engaged, the geographic location
of the practice, financial considerations, regulatory concerns, and pre-existing
contracts. Because the Company owns no equity interest in the Core Medical
Groups and is not engaged in the practice of medicine, the Company does not
reflect physician revenues in the Company's financial statements.
 
     FOCUS ON PRIMARY CARE PHYSICIANS.
 
     Consistent with the Company's primary care-driven strategy, the primary
focus of the Company's contractual arrangements with physicians has been
establishing relationships with PCPs. Since the Company's inception, entities
have been formed or consolidated to conduct group medical practices as Core
Medical Groups. Each Core Medical Group is comprised of a group of physicians
under common management and with a common information system and provider number
and is designed to provide a full and coordinated spectrum of medical services
to patients and meet Payors' needs. To date, Core Medical Groups have been
formed in five geographic markets in Maryland using a limited liability company
organizational structure.
 
                                       36
 
<PAGE>
     From February of 1995 to December 31, 1995, the Company assumed exclusive
management responsibility for and became the sole contracting entity for 32 PCP
practices through Baltimore Medical Group, LLC, and Carroll Medical Group. Since
December 31, 1995, the Company assumed, or entered into binding letters of
intent to acquire certain assets and became the sole contracting entity for an
additional 43 PCP practices. Thus, as of January 10, 1997, a total of
approximately 75 PCPs have transferred their medical practice assets and became
employees of the various Core Medical Groups, or have entered into binding
letter agreements to transfer their medical practices and become employees.
 
     Although the details of each transaction may differ, the practice of the
Company upon establishment of a Core Medical Group is to enter into a Practice
Participation Agreement with the Core Medical Group and each of the Equity
Physicians who is a member of such Core Medical Group, pursuant to which the
following transactions occur:
 
     TRANSFER OF MEDICAL PRACTICES. Under the Practice Participation Agreement,
an Equity Physician transfers to the Company certain medical practice assets as
well as contract rights under certain business contracts of the medical
practice, to the extent that such rights are assignable. The Company may also
assume specified liabilities or obligations of the medical practice. Although
the form of consideration paid to such Physicians may vary, typically the
Physician receives a combination of cash and Securities of the Company. For a
description of such Securities, see "Description of Capital Stock." The amount
and type of consideration payable to each Physician is determined by negotiation
between such Equity Physician and the Company. Such transactions consist of an
acquisition by the Company of certain tangible and intangible assets of the
medical practice, including contract rights, and the collection by the Company
of the accounts receivable of the Physician. Such transactions do not convey to
the Company an equity interest in the Core Medical Groups.
 
     REACQUISITION RIGHTS. The acquisitions are generally subject to
reacquisition rights whereby the Physician may rescind the transaction typically
within a nine-month period from the date of closing. Pursuant to such
reacquisition rights, the Physicians may repurchase substantially all of the
assets previously acquired by the Company at the price paid by the Company at
the closing. Any Securities acquired by the Physician in connection with the
acquisition will be transferred back to the Company upon the reacquisition.
 
     EMPLOYMENT OF PHYSICIANS BY THE CORE MEDICAL GROUP. Each Physician enters
into an Employment Agreement with the Core Medical Group of which he is a
member. Typically, Employment Agreements have a term of 10 years, during which
time the Physician will be obligated to devote his full professional time to the
practice of medicine with, for and through such Core Medical Group. As an
inducement to sign the agreement and as an incentive to remain as an
employee-physician, each "full time" PCP also may receive additional shares or
options of Class B Common Stock. The Employment Agreement provides for the
payment of a base salary and benefits and for the eligibility of such Physician
to participate in distributions from a bonus pool (each, a "Core Medical Group
Bonus Pool"). Each Core Medical Group Bonus Pool is distributed by the
Management Committee of the Core Medical Group and rewards high clinical
quality, appropriate utilization, patient satisfaction and retention, and
general cooperation and attitude. The employed physician may be eligible to
participate in such distributions in such years in which such physician meets or
exceeds such standards as may reasonably be required by the Management
Committee. See "--Operation of the Core Medical Group".
 
     The base salary of PCPs in most Core Medical Groups is generally an amount
equal to the sum of certain revenues collected on behalf of the Core Medical
Group by the Company in respect of the physician services provided by such
physician, less the allocated costs attributable to the medical practice of, and
provision of related health care services by, such physician. The Company and
certain of the Physicians employed by Doctors Health Montgomery agreed that
Doctors Health Montgomery will provide base salaries to such Physicians. In
return for its commitment to provide financial resources, if necessary, for such
Physician's salaries, the Company and Doctors Health Montgomery will receive a
percentage of the growth in revenues generated by their medical practices and
other fees.
 
     PSO AGREEMENT WITH THE CORE MEDICAL GROUP. The Company provides managed
care contracting and practice management services to the Core Medical Groups
(and indirectly to its Physicians) pursuant to 30 year PSO Agreements (with
automatic, renewable 10 year terms) entered into between the Company and each
Core Medical Group. The following is a summary of the principal provisions of a
PSO Agreement. The PSO Agreement does not convey to the Company an equity or
similar interest in the Core Medical Groups.
 
     The PSO Agreement typically gives the Company the exclusive right to
provide to the Core Medical Group (i) all of the non-medical management and
financial services, including provision of non-physician employees, office space
and other facilities, equipment, assets, goods and supplies, that the Core
Medical Group and its Physicians will use to engage in the practice of medicine
and (ii) other related services.
 
                                       37
 
<PAGE>
     Pursuant to a typical PSO Agreement, the Company is given discretion and
authority to manage and conduct the business affairs of the Core Medical Group
and is appointed the agent and attorney-in-fact of the Core Medical Group to
enable the Company to fulfill these functions. The Company negotiates for and
enters into agreements with Payors for health care services, including managed
care contracts providing for compensation on a capitated basis, that will
obligate both the Core Medical Group and its Physicians to provide medical
services at the levels of compensation negotiated solely by the Company. The
Company also negotiates for, and enters into agreements with, other providers of
medical services for the provision of medical services to the patients of the
Core Medical Group and for the provision of medical services to such providers
by the Core Medical Group and its Physicians, all on terms and for the
compensation determined solely by the Company. The Company has a broad range of
financial responsibility and authority by the Core Medical Group pursuant to the
PSO Agreement, leaving the Core Medical Group with the right to manage only
those professional components of its business requiring a license to practice
medicine.
 
     PSO Agreements typically provide that the Company is entitled to an amount
equal to the difference between (i) the cash it collects on behalf of the Core
Medical Group and each of its physicians in receivables which have been conveyed
to the Company and (ii) the amount paid out by the Company in respect of the
business costs and expenses of the Core Medical Group. The Company will pay that
amount over to itself in each month during which there is sufficient cash in the
Core Medical Group's accounts, in the discretion of the Company, to pay the
amount after satisfying all of the Core Medical Group's business costs and
expenses, including such reserves therefor as the Company deems appropriate, and
including all accruals for unpaid base salaries of the physicians of the Core
Medical Group for prior periods. The Company may reserve the right to charge
separate fees for additional services, as agreed between the Company and the
Core Medical Group.
 
     PSO Agreements with PCP Core Medical Groups provide that the Company may
pay to the Core Medical Group, as a Managed Care Incentive Payment, an annual
negotiated amount of up to 25% of the total amount of all Company net income
before taxes and bonuses, attributable to the provision of health care to the
Core Medical Group's managed care patients during each calendar year, not to
exceed, in the aggregate, 25% of the base salaries paid to all PCPs of the Core
Medical Group. Such payments are not required if the Company has not earned net
income during the applicable years. Such payments may be utilized by the Core
Medical Group to fund the Core Medical Group Bonus Pool in which the physician
employees of the Core Medical Group may participate. See "--Employment of
Physicians by the Core Medical Group." It is anticipated that the full amount of
any Core Medical Group Bonus Pool will be paid out by the Core Medical Group to
its physicians as bonuses in each year.
 
     PSO Agreements that will govern the Company's relationship with specialists
will typically provide for (i) a term of 30 years with automatic, renewable 10
year terms; (ii) a commitment among the specialist group and the Company to
develop innovative, risk sharing payment arrangements; and (iii) use of
commercially reasonable efforts to provide the specialist group with managed
care referrals. Such specialist PSO Agreements will also provide for payment of
a management fee consisting of a negotiated percentage of actual operating costs
of the specialist Core Medical Group (excluding compensation to the group's
Physicians) and a percentage of collections available after payment of operating
costs, the Company's operating cost percentage, and the physician compensation.
 
     All of the PSO Agreements in effect have terms of 30 years (with automatic
10 year renewals) and generally may be terminated prior to expiration of its
term only under limited circumstances. Generally, absent insolvency, malfeasance
or a material uncured breach, the PSO Agreement cannot be terminated by the
Company or the Core Medical Group.
 
     The Company's structure and the clinical independence of the Core Medical
Groups enable the Core Medical Groups' member physicians to retain their
autonomy through their ownership interests in the Core Medical Groups and
control over clinical decisions. The Company believes this governance structure
has been critical to the Company's success in the early stages of its
development.
 
     OPERATION OF THE CORE MEDICAL GROUP. Each physician joining a Core Medical
Group enters into an Operating Agreement or similar agreement with each of the
other physicians in the Core Medical Group. Pursuant to the Operating Agreement,
the business and affairs of the Core Medical Group are managed under the
direction and control of a Management Committee, one of whom is the Chief
Executive Officer of the Company (or his designee) serving EX OFFICIO. The
Management Committee has the power, among other things, to determine the amount
of any or all bonuses payable pursuant to the Core Medical Group Bonus Pool
which it delegates to a Bonus Committee. The Members of the Management Committee
are elected by the affirmative vote of the Physicians of the Core Medical Group
(other than the Company designees). The Bonus Committee also establishes, in
consultation with the Company and the bonus committees of other Core Medical
Groups, practice protocols.

     INDEPENDENT PHYSICIAN ASSOCIATIONS.
 
     The Company has expanded its network by contracting with physicians in a
variety of ways through IPAs in which IPA Participant Physicians authorize the
IPA to negotiate service contracts on their behalf. In some cases, the Company
contracts with or through an existing IPA, while in other cases the Company
assists physicians who may wish to establish an IPA. The models utilized by the
Company involving IPAs consist of Exclusive IPAs, pursuant to which a physician
is obligated to conduct all managed care contracting through the Company,
Non-Exclusive IPAs, pursuant to which a physician may contract for managed care
with others but agrees to take all patients referred by the Company, and other
contractual arrangements which may involve a physician contracting for managed
care through others or choosing to accept or deny patients referred by the
Company. In some cases, the Company may issue Securities as incentives for
physicians to enter into Exclusive IPA Agreements. The Company may also issue
Securities to employees of the Company as compensation for the recruitment of
physicians to join the Company's IPAs.
 
     COMPANY CREATED IPAS; PREVIOUSLY EXISTING IPAS: The Company may assist in
the creation of an IPA or may contract with a previously existing IPA or
independent medical group. In the case of previously existing IPAs or groups, in
addition to being subject to the various types of contractual arrangements
discussed below to which the Company is a party, the IPA and its network
physicians will also be subject to a previously existing participation agreement
among the previously existing IPA and its network physicians. In such cases, the
previously existing IPA also enters into a network agreement with the Company
which governs the contractual relations between the IPA and the Company. The
network agreement will contain provisions unique to the situation of each
existing IPA with which the Company contracts but should typically contemplate
the provision of various management services by the Company to the IPA and the
appointment of the Company as the IPAs agent and attorney-in-fact for the
purpose of negotiating managed care contracts with risk sharing arrangements for
the IPA on an exclusive or non-exclusive basis and providing other services such
as billing and information systems.
 
     ORGANIZATION OF THE IPA: The IPA is typically organized as a corporation or
limited liability company. Each of the IPA Participant Physicians enters into an
operating agreement among each of the other Participant Physicians in the IPA.
Pursuant to such operating agreement, each Participant Physician will agree to
be bound by the by-laws of the IPA which contain substantive requirements for
participation in the IPA.
 
     EXCLUSIVE IPAS: The IPA Participant Physician enters into an Exclusive IPA
Agreement with the Company and the IPA in which he participates, pursuant to
which the Company markets the physician to Payors, and includes the physician in
its provider network. The IPA Participant Physician may choose to participate in
Exclusive IPA Agreements for either Medicare or commercial products offered by
HMOs with whom the Company contracts, pursuant to which such physician agrees to
contract exclusively with the Company for Medicare or commercial managed care
contracts, respectively. As of January 10, 1997, 84 physicians were
participating with the Company's Exclusive IPAs. Although there can be no
assurances, the Company expects that additional physicians will commit to
participate in Exclusive IPAs.
 
     Under an Exclusive IPA Agreement, an initial primary care base capitation
rate and risk-sharing arrangements are negotiated between the Company and the
IPA. The IPA Participant Physician may also be eligible to participate in a
bonus pool. A one-time incentive payment, or periodic panel growth and managed
care bonuses which may include cash or Securities, may also be payable by the
Company pursuant to an Exclusive IPA Agreement. Further, the agreement may
contain a practice option, pursuant to which the physician may elect, subject to
the satisfaction of certain conditions, to sell his or her medical practice to
the Company.
 
     NON-EXCLUSIVE IPAS: The IPA Participant Physician enters into a
Non-Exclusive IPA Agreement with the Company and the IPA, pursuant to which the
Company markets the physician to Payors under capitation contracts and includes
the physician in its provider network. The physician reserves the right to
contract directly with HMOs or other Payors, and to participate in other IPAs,
but usually agrees to accept managed care patients referred by the Company, up
to agreed-upon levels. Other provisions of the Non-Exclusive IPA Agreement may
be similar to the provisions of the Exclusive IPA Agreement.
 
     JOINT VENTURE ARRANGEMENT. The Company has entered into a Contracting and
Managed Care Services Agreement with an organization which operates health care
facilities in Baltimore City, and employs and contracts with approximately 37
physicians in Maryland. Under the arrangement, the Company acts as the
organization's exclusive contracting entity for Medicare and Medicaid managed
care contracts. The arrangement involves a sharing of Managed Care surplus and
losses between the parties.
 
     OTHER CONTRACTUAL ARRANGEMENTS. Although other contractual arrangements may
take a variety of forms, generally these arrangements involve the IPA
Participant Physician entering into an agreement with the Company pursuant to
which the
 
                                       39
 
<PAGE>
Company markets the physician to Payors but the physician reserves the right to
participate in other IPAs and to determine whether to accept managed care
patients referred by the Company.
 
     CONTRACTING WITH SPECIALISTS, HOSPITALS AND OTHER HEALTH CARE PROVIDERS
 
     The Company contracts with specialists, hospitals and other providers of
health care services as part of its effort to develop an integrated health care
delivery network.
 
     CONTRACTING WITH SPECIALISTS: The Company contracts with specialist
physicians for the provision of services to the Company and the Core Medical
Groups in a variety of ways, generally consisting of employment in a Core
Medical Group, or contractual arrangements involving reduced fee-for-fee service
or sub-capitated arrangements. Other than employment in a Core Medical Group and
the formation of a cardiology Core Medical Group (see "Business--History of the
Company--Formation of Cardiology Core Medical Group"), arrangements with
specialists typically have terms of between one and five years. Specialists may
under appropriate circumstances also receive an equity interest in the Company.
 
     CONTRACTING WITH HOSPITALS AND OTHER PROVIDERS: The Company contracts with
hospitals ("Participant Hospitals") and other health care providers to
participate in its managed care networks. The Company envisions that many of its
arrangements with Participant Hospitals may involve "key hospital" arrangements.
The Company and the Participant Hospital will enter into a Hospital
Participation Agreement ("Hospital Participation Agreement"), pursuant to which
the Company will agree to make the hospital the referral hospital of choice for
specified categories of managed care patients and specified categories of
service. The Participant Hospital must meet cost and quality standards and agree
to cooperate with the Company in the implementation of utilization review, to
include preadmission guidelines and processes, patient care and cost tracking,
information exchanges and management reporting systems and the development of
innovative pricing arrangements. The Company also negotiates contractual
arrangements with other health care providers (for example, home health care
aides) as needed to deliver quality and cost-effective service to patients.
Although the term of such arrangements would vary, the Company expects to
negotiate discounted fee-for-service or sub-capitated arrangements with such
providers.

PHYSICIAN RECRUITMENT
 
     The Company recruits physicians through direct marketing efforts, Core
Medical Groups, and IPAs. The Company has a physician recruitment staff managed
jointly by the Company's Chairman, who is Executive Vice President of Corporate
Development, and the Executive Vice President of Strategic Planning. The Company
also employs a Director of Recruiting, recruiting assistants and other staff.
The Company also recruits PCPs through relationships with current Core Medical
Group physicians, IPA Participants and other contacts. The Company also seeks
assistance from recruiting consulting arrangements. Such recruiting consultants
provide the Company with access to potential Network Physicians.
 
MANAGED CARE CONTRACTING
 
     CONTRACTS WITH PHYSICIANS, HOSPITALS AND OTHER PROVIDERS OF HEALTH CARE.
 
     As discussed above in "--PSO Agreement with the Core Medical Group" and
"--Independent Practice Associations," the Company is authorized to negotiate
for and enter into agreements with Payors for health care services, including
managed care contracts providing for compensation on a capitated basis, that
will or may obligate Core Medical Groups and their respective physicians, IPAs
and their respective IPA Participant Physicians and other physicians to provide
medical services at the levels of compensation negotiated solely by the Company.
Further, as described above in "--Contracting with Specialists, Hospitals and
other Health Care Providers," the Company is also authorized to negotiate for
and enter into agreements with Payors for the provision of services available
from such providers. The Global Capitated Contracts and certain Gatekeeper
Capitated Contracts have been executed by the Company and an HMO or other Payor.
The Core Medical Groups and Network Physicians are not parties to the Global
Capitated Contracts. The Core Medical Groups and Network Physicians may be party
to Gatekeeper Capitated Contracts pending conversion to the Company's Contracts.
 
     The Company's goal is to enter into shared risk arrangements with HMOs and
other Payors and to enter into full capitation/full risk arrangements with such
Payors. The Company believes that its capabilities in information systems and
care management will allow it to operate successfully and manage patient care in
a rapidly changing environment. See "Control of Patient Data and Information
Systems." The Company believes that the access to the Company's information
management systems and bonus payments for Physicians in Core Medical Groups and
IPA Participant Physicians in IPAs will allow such physicians to exercise
appropriate control over the cost of health care, providing better care at lower
overall cost. See "--PSO Agreement with the Core Medical Group" and
"--Independent Practice Association."
 
     CONTRACTS WITH PAYORS.
 
     The Company enters into contracts with Payors on behalf of Network
Physicians. Global Capitated Contracts typically obligate the Company to provide
and pay for all physician services (except for negotiated carve-outs) and, in
certain contracts, hospital and ancillary services for a percentage of the
premium or a fixed capitated amount. The Company then subcontracts with
physicians and other health care providers to provide the required services in
compliance with the Company's care protocols when applicable. The payment from a
Payor to the Company is typically calculated based on the number of Members of
the HMO enrolled with the Company's PCPs. Such Payor contracts generally have
terms of approximately one year and, after the initial term, are renewable for
one-year terms unless canceled by either party. In its Payor contracts, the
Company currently attempts to assume risk for all services, except mental health
and pharmacy. Eye care, home health and durable medical equipment (DME) also may
be carved out of the Company's risk due to more competitive terms for these
services being available to Payors based on their existing national
relationships. The Payor in each contract also retains a percentage of the
premium to perform marketing, enrollment and some administrative services.
 
     In entering into or renewing Payor contracts, the Company considers a
number of specific factors which affect capitated rates, the amount of the
shared risk and scope of covered services for which the Company is responsible.
These factors include, but are not limited to, the demographic risk profile of
the enrollee pool, the premium received by the Payor, prior financial
experience, cost and availability of stop-loss protection and an understanding
of the fee-for-service equivalent charges. In addition, the Company will work
with certain HMOs to establish preferential and/or partnership type
relationships in which incentives are provided in the contract to reward the
Company for accepting and retaining a high number of the plan's Enrollees. In
undertaking this process, the Company analyzes pertinent data in order to assess
the providers' contractual and economic opportunity and exposure, and then
conducts the negotiations on behalf of the physician networks.
 
                                       42
 
<PAGE>
PRACTICE MANAGEMENT SERVICES
 
     The Company recognizes the administrative burdens associated with the
practice of medicine and recognizes that time spent by a physician managing a
medical practice reduces the time available for providing medical care to
patients. Accordingly, the Company's operations consist in large part of
providing medical practice management services to its Network Physicians who
join Core Medical Groups, thereby allowing the physicians to concentrate on
providing quality care to patients.
 
     Under the Company's PSO Agreements with the Core Medical Groups, the
Company provides the Core Medical Groups and their employed physicians with
administrative and financial services, including information systems and billing
services, and provides facilities, non-medical staff personnel, equipment and
other goods. The Company operates a billing and claims processing center in
White Marsh, Maryland which processes claims, generates and delivers bills to
patients and payors, and collects amounts owed. The practice management services
provided by the Company also include maintaining the financial and business
books and records of the Core Medical Groups, providing legal support, providing
marketing and advertising, and paying for costs and expenses incurred in
connection with the operation and administration of the Core Medical Group's
practice of medicine. The Company also leases as tenant medical office space and
subleases such space to the Core Medical Groups, employs the non-physician staff
personnel who assist the physicians, and provides or arranges for the provision
of the furniture, fixtures and equipment used by the physicians in their
practices.
 
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.
 
     The Company's information systems strategy consists of using sophisticated
hardware and software to (i) monitor PCP referrals to specialists, hospitals and
other providers; (ii) collect information regarding PCP compliance with medical
care protocols; (iii) allow physician offices to use Company-installed hardware
for billing through the Company's billing and claims management staff; and (iv)
eventually provide the Company and its care management staff with direct
computer access to hospitals in order to facilitate quality and cost-effective
care of Core Medical Group patients.
 
     The Company believes that its information systems will encourage exchange
of information among the Company's utilization review and care management staff
and physician practices, hospitals and other providers in the Company's provider
network to allow the Company to react promptly to changes in patient care
requirements, costs and utilization issues. The Company makes its information
systems available to all Core Medical Groups and Equity Physicians currently
participating in its networks and will make such systems available on a uniform
basis to other providers when they meet certain threshold requirements, while
also tailoring the system to meet unique needs of individual medical practices
to best serve the patients.
 
CARE MANAGEMENT
 
     The Company believes the most successful approach to managing risk and the
costs associated with that risk is through the care management process. Care
Management seeks to promote the wellness of patients, control costs, encourage
patient satisfaction and provide better integrated health care with services
provided by the Core Medical Groups and other Network Physicians. The Company's
care management program consists of credentialing, utilization review and
referral management, disease management, case management, and quality assurance.
These programs seek to improve and preserve the quality of health care services
provided by the Core Medical Group's physicians and other Network Physicians and
control the cost of medical care. Under certain of the Company's Global
Capitated Contracts, Payors have delegated to the Company utilization review and
care management. The Company employs 17 care management personnel with nursing,
social work, case management and other patient care management experience to
assist in coordination of quality health care for a potential population of
80,000 members. All of the Company's care management staff are registered nurses
or licensed social workers and are required to possess the Certified Case
Manager designation from the Commissioner of Case Manager Certification.
 
     All Network Physicians must complete the Company's credentialing process.
In accordance with the Company's credentialing policies and procedures,
physicians submit a comprehensive application to the Company's credentialing
staff. The application materials are reviewed by the Company and submitted to an
external credentialing verification organization, which provides primary source
verification of information submitted in the application. The application is
then submitted to

<PAGE>
the Company's Physician Credentialing Committee and Medical Director for
approval. The Company's credentialing process helps ensure the quality of its
Network Physicians and promotes the quality of care provided to patients.
 
     The Company also performs referral and utilization management. The
Company's utilization management staff reviews for medical appropriateness all
referrals by Network Physicians under the Company's Global Capitated Contracts
to other providers for the use of ancillary services, and for inpatient hospital
admissions. The Company utilizes health care management guidelines that are
widely accepted in the health care industry to review referrals for clinical
appropriateness. The Company shares the guidelines with physicians and prepares
and provides other educational programs regarding utilization and referrals,
including comparative data, to its Network Physicians. Network Physicians
provide information regarding referrals to the Company's utilization management
staff which reviews referrals for services not provided by Network Physicians.
The Company's utilization management coordinator and Medical Director perform a
network assessment and appropriateness review. Utilization and referral
management is a critical component of the Company's operations because it
promotes the effective and efficient use of medical resources, controls the cost
of medical care, and contributes to the Company's ability to negotiate and
obtain favorable shared risk arrangements with payors.
 
     The Company seeks to promote wellness and avoid hospitalizations, reduce
length of in-patient stays, and otherwise reduce costs associated with
high-frequency and high-cost chronic patient conditions through its disease
management program. The Company's program is currently focused on three of the
most expensive and debilitating ailments suffered by Medicare patients,
congestive heart failure, diabetes, and chronic obstructive pulmonary disease.
The disease management process involves physicians and employees from many of
the Company's departments, including care management, utilization management,
case management, social workers, education specialists, physician liaisons and
contracting. The Company gathers data and other information regarding these
conditions, such as morbidity and mortality statistics, length of stay and
hospital admission rates, and other data related to the cost of care associated
with such conditions. The Company also identifies patients participating in its
Global Capitated Contracts that are at risk or suffering from one of these
conditions. Physicians design a recommended disease-specific medical approach,
and the Company's employees involved in disease management, utilizing the
resources of many of the Company's departments, develop a plan to provide
cost-effective, high quality care to patients suffering from ailments.
Specifically, the Company establishes utilization and referral parameters,
develops specialized pharmaceutical and nutritional programs, provides education
to patients, monitors specific cases and provides patient support.
 
     The Company develops its clinical protocols in consultation with physicians
and other sources. Physicians in the Company's networks remain free to diverge
from the protocols when they determine that it is medically appropriate to do
so. The Company's contracts with physicians and other health care providers
expressly state that the Company shall not interfere with the physician's
relationship with and responsibility to the patient. While the clinical
protocols and procedures may assist the physician in providing cost-effective
and high quality care, the physician remains free and has the duty under all of
the Company's contracts to treat patients as he deems necessary, and not to
discriminate against patients covered by the Company's managed care plans.
 
     The Company's case management program also focuses on patient satisfaction
and cost savings by identifying patients whose diagnosis will require
significant medical care. The Company's staff of case 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 case 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.
 
     In order to help ensure the quality of health care services to patients and
manage the costs of health care, the Company's care management department
administers a quality assurance program which monitors patient satisfaction,
compliance with HEDIS standards and quality of medical records. The care
management department conducts reviews of random samples of cases to monitor
consistency with the Company's policies and procedures regarding referral
management, utilization management and case management. The Company's care
management department has developed and implemented its policies and procedures
in compliance with the standards as specified by certain national accreditation
organizations for the health care industry.

COMPETITION
 
     The Company's provider network competes with other provider networks and
medical groups, including those established by hospitals and other individual
physicians, and IPAs in obtaining managed care contracts with health maintenance
organizations and other Payors. The competitive factors that the Company
encounters include the number of physicians in each group, geographical coverage
of Network Physicians, the quality of care that can be provided to the Payors'
enrollees, and the ability to effectively manage care. The Company believes that
it can successfully compete with other entities seeking managed care contracts
with Payors because of the Company's large number of Network Physicians, thereby
providing Payors with an extensive network of providers to offer the Enrollees
of the Payors with whom the Company contracts. The Company also has an
increasing geographic coverage of Network Physicians with extensive coverage in
the Baltimore metropolitan area and Core Medical Groups (either existing or with
letters of intent) or IPAs in Allegany, Carroll, Anne Arundel, Harford, and
Montgomery Counties. However, a large number of physicians remain who may join
other provider networks and who may be competing for managed care contracts. The
Company also believes it can effectively compete with other networks because it
was one of the first established physician owned networks in Maryland, although
other provider networks in the region have recently been developed and the
Company expects others to be established.
 
     The Company competes with certain HMOs, other Payors, other provider
networks, medical groups, and hospitals in acquiring certain assets of physician
practices. Further, large established traditional indemnity insurance companies
also are entering the managed care field and may compete with the Company in
acquiring certain assets of physician practices and developing physician
networks. Certain of the Company's competitors (i) employ physicians, (ii) own
such physicians' medical practices, clinics or medical groups and (iii) exercise
broad control over clinical decisions of such physicians and their medical
practices. Competitive methods include the type and amount of compensation
offered to physicians in exchange for their practices, the level of clinical
autonomy afforded the physician, terms of employment arrangements, the level and
extent of care management imposed on the physician, and the types of management
services that will be provided to physicians. The Company believes it can
effectively compete with other groups in acquiring certain assets of physician
practices because the Company is driven by primary care physicians and primary
care strategies. Although other entities may offer cash consideration for
physician practices in amounts greater than the Company, the Company believes
that offering an equity interest in the Company to its physicians provides an
incentive of ownership which will encourage the implementation of managed care.
The Company believes its physician ownership will attract greater numbers of
physicians to its network, and because of the significant percentage of the
Company which is owned by physicians, such physicians will be better able and
more willing to implement managed care. Further, the Company believes that it
provides its Network Physicians with greater clinical autonomy than may be
offered by hospitals, HMOs or insurance companies.
 
     The Company also will compete with other management companies providing
management services to physicians. While many of these companies have greater
marketing and financial resources than the Company and may be better able to
provide services to its health care providers, the Company will provide
comprehensive business management services to its Equity Physicians and certain
of its other Network Physicians, including administrative, legal and accounting
services, billing and collection services, referral management, utilization
review, and computer systems and training, thereby providing such physicians
more time to devote to the practice of medicine. See "Risk
Factors--Competition."
 
EMPLOYEES
 
     As of January 10, 1997, the Company had approximately 450 employees, of
which approximately 140 are full time employees in its headquarters in Owings
Mills, Maryland and approximately 310 have been assigned by the Company to work
in physician offices. An additional 104 physicians and laboratory personnel are
employed by the affiliated Core Medical Groups.
 
PROPERTIES AND ASSETS
 
     The Company leases approximately 25,800 square feet in Owings Mills,
Maryland for its corporate headquarters. The term of the lease continues until
2001. The Company also has entered into a sublease through 1999 and a lease
through 2002 for approximately 18,770 square feet in Baltimore, Maryland for its
billing and claims processing operation. 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 certain assets of the medical practices of Equity Physicians, computer
hardware and software, the rights granted to it pursuant to the PSO Agreements,
contractual relations with providers and Payors, accounts receivable, and cash.
 
     The Company has filed service mark applications to register its logo and
corporate names "Doctors Health System Managing Quality Health Care", "Doctors
Health", and "Doctors Health, It's the Sure Sign of Caring".
 
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 CMGs 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, "Stark" 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.
 
     The Company has recently commenced managed contracting on behalf of an IPA
in northern Virginia and may, therefore, be subject to Virginia law. The Company
has determined that Virginia law, as currently interpreted and applied, with
respect to "fraud and abuse", restrictions on physician self-referral, HMO and
insurance company licensing and the corporate practice of medicine are
substantially similar to Maryland law. Accordingly, the Company believes that
its current operations are in material compliance with Virginia law.
 
     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 ("DMS"), through the
Office of the Inspector General (the "OIG"), may bring civil actions for
monetary penalties and to exclude individuals from participating in the Medicare
or Medicaid programs for violations of the fraud and abuse rules. The fraud and
abuse rules are broadly drafted, and have been broadly interpreted by courts.
Read literally, the fraud and abuse rules may prohibit not only kick-backs but
many legitimate business arrangements and joint venture activities. Many states
have adopted rules similar to the fraud and abuse rules. While the Company
believes that its activities do not violate the fraud and abuse rules, there can
be no assurance that federal or state regulators might not challenge some of the
Company's activities.
 
     Concerned that legitimate business arrangements were being stifled by the
fraud and abuse rules, Congress directed DMS 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
proposed from time to time. Some of these Safe Harbors are applicable to the
activities of the CMGs, 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. Basically, all lease
and services agreements must be in writing, describe all services to be
provided, be on commercially reasonable terms, and 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
 
                                       46
 
<PAGE>
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 STATE LAW REGARDING RESTRICTIONS ON PHYSICIAN SELF-REFERRAL
 
     Federal law, generally referred to as the "Stark II" legislation , as well
as the law of Maryland and Virginia and 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
the provider, including a direct or indirect ownership or investment interest,
or a compensation arrangement with a provider (including the physician's own
CMG), 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, physician 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, and is not within an exception,
(i) neither the patient nor the payor may be billed; (ii) payors can recover all
amounts previously billed and paid in respect of non-excepted self-referrals;
and (iii) the referring physician and the provider are jointly and severally
liable to repay any amounts paid in respect of non-excepted self-referrals. Both
State and Federal law also impose 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 CMGs, and the physician members of
the CMGs, 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 CMGs and with IPA entities.
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 or
statutes might require the Company to restructure its relationships with the
CMGs and other managed care networks, and violation of Stark II by the Company
or its CMGs could result in significant fines and financial losses which could
adversely affect the Company.
 
     ANTITRUST
 
     The affiliated CMGs and the Company's other Network physicians 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 Federal Trade Commission has 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.
 
     INSURANCE
 
     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. The Company cannot,
without an HMO license, offer or sell to individuals or companies health
 
                                       47
 
<PAGE>
insurance or the opportunity to purchase health insurance from the Company or
hold itself out or advertise as an insurer or HMO.
 
     On August 10, 1995, the NAIC issued a report opining that risk-transferring
arrangements may constitute the business of insurance to which state licensing
laws apply. The NAIC opined that such licensing laws would not apply to the
Company's Global Capitated Contracts or Full Risk Contracts because the Company
assumes "downstream risk" from a duly licensed health insurer or HMO for health
care provided to that carrier's Enrollees. The NAIC's conclusions are not
binding on the states.
 
     In Maryland, for example, licensed HMOs are permitted to enter into
capitation arrangements with entities like the Company which assume the
obligation to pay providers directly as long as the HMO has obtained approval
for the form of the "administrative service provider contract" with the entity.
In particular, an administrative service provider is not required to be licensed
as an HMO if such provider accepts the risk of providing and paying for the
medical services required by Enrollees of an HMO. In connection with accepting
such risk, the Company organizes networks of physicians, provides
administrative, care management, utilization review, referral management and
other services necessary to profitably accept managed care risk. All of the
Company's Global Capitated Contracts are administrative service provider
contracts with licensed HMOs. The Attorney General of the State of Maryland has
issued an advisory opinion that calls into question the ability of an unlicensed
entity to provide health care services under global capitated contracts in
situations where a licensed HMO was not the entity contracting with the insured,
and the Company has no such arrangements and no present intention to enter into
any such arrangements. The Company has no present plans to become an HMO or
insurance company licensed to offer health insurance in Maryland or elsewhere,
and intends to continue to offer services under Global Capitated Contracts only
under administrative service provider contracts.
 
     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. The Company is required under its Global Capitated Contracts to either
post a letter of credit or create a segregated fund for the benefit of health
care providers which provide services to enrollees under Global Capitated
Contracts to which the Company is a party. These added financial requirements
have not created any financial burden to date for the Company.
 
     CORPORATE PRACTICE OF MEDICINE AND THE PROHIBITION AGAINST FEE SPLITTING
 
     Physicians must be licensed in order to practice medicine. Both Maryland
law and the ethical rules of the American Medical Association and Medical
Chirurgical Society of Maryland prohibit fee splitting, which is generally
defined, as relevant here 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, but not in Maryland,
Virginia, nor any of the other states contiguous to Maryland, has been coupled
with the corporate practice of medicine doctrine to question management
agreements pursuant to which non-physicians in a management company obtain
substantial financial benefits from a physician practice. The Company's
management has no evidence that Maryland or its neighboring states would choose
to follow those states which have sought to prohibit management agreements as
fee splitting, and Maryland, in particular, expressly permits entities organized
as LLCs to engage in the practice of medicine.
 
     The corporate practice of medicine doctrine is founded in state medical
licensure statutes which prohibit the practice of medicine without a license.
Corporations, which cannot be licensed, are therefore prohibited from practicing
medicine. The corporate practice doctrine was originally designed to protect the
public against commercial exploitation of medicine by middlemen intervening in
the doctor-patient relationship to make a profit. It is unlawful to practice
medicine in Maryland without a license. Practicing medicine with an unauthorized
person or aiding such person in the practice of medicine is grounds for
disciplinary action, including license revocation.
 
     To permit physicians to practice medicine in a corporate form, Maryland and
each of the contiguous states, including the Commonwealth of Virginia, has
adopted a professional corporations ("PC") statute. Under Maryland's
Professional Service Corporations statute, a corporation that is eligible to be
a PC may not organize under any other corporate form. This precludes use of a
general corporation to render professional services. A PC may only render
professional services through individuals licensed or otherwise authorized to
provide them. The majority of the directors and officers of the PC must be
qualified persons. Moreover, a PC may only issue stock to a licensed individual,
general partnership comprised entirely of licensed members, or a PC organized to
perform the same professional service, and stock may only be transferred to a
 
                                       48
 
<PAGE>
qualified person. Consequently, a non-licensed individual could serve as a
director, but could not own stock or vote in the PC.
 
     However, a Maryland limited liability company ("LLC") may render
professional services, including medical services. There is no requirement that
all members of an LLC organized to perform professional services be licensed.
Each of the CMGs is organized as an LLC in accordance with Maryland law. The
Company does not employ any physicians to provide medical services, and operates
in strict accord with Maryland law.
 
     The Company will operate as management company on behalf of the CMGs and
will enter into Managed Care contracts with Managed Care companies in which the
CMGs and IPAs and other physician groups participate. The management of the
Company believes that, under the presently applicable interpretations of
Maryland law and ethical rules applicable to the practice of medicine in
Maryland, the activities of the Company under the PSO Agreement are not in
conflict with or violation of any applicable legal or ethical requirements
imposed on the practice of medicine or on fee splitting. The Company charges a
management fee for some services, but the physicians in the CMGs do not share
fees with members of other CMGs or with 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 to substantially 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.
 
     The Maryland statute and Stark II have been recently enacted and there is
considerable uncertainty concerning how they will be interpreted, including
specifically how broadly the exemptions and exceptions to their application will
be applied. Regulations applying to Stark I and applicable to some, but not all,
of Stark II have recently been adopted. The Core Medical Groups, and the Equity
PCPs, as well as other entities that contract with the Company through
arrangements similar to the IPA arrangements described above, will have both an
ownership interest in and a compensation arrangement with the Company, and the
physicians will have similar relationships with the Core Medical Groups and with
IPAs. Physicians will refer patients among themselves within their practices and
as part of the managed care networks which the Company will establish. The
Company believes that it is not an entity to which referrals can be made, and
that the referrals of patients by participating physicians within the managed
care networks managed by the Company should fall within one or more of the
exceptions permitted by Stark II and the state self referral laws. Future
regulations, statutes or interpretations might require the Company to
restructure its relationships with the Core Medical Groups and other managed
care networks, and violation of Stark II by the Company or its Core Medical
Groups could result in significant fines and financial losses which could
adversely affect the Company.

     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-
 
                                       54
 
<PAGE>
qualified stock options shall be as determined by the Compensation Committee.
Incentive stock options may be granted only to employees of the Company. The
terms of each option may not exceed ten years from the grant date. As of January
10, 1997, the Company has granted options to purchase 579,380 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
341,630 of such options granted is $.01 per share, 70,000 options have an
exercise price of $11.00 per share, 68,500 have an exercise price of $15.00 per
share, 10,000 have an exercise price of $18.75 per share, 29,250 have an
exercise price of $20.00 per share, and 60,000 have an exercise price of $30.00
per share. Of such options, 185,130 were granted on August 10, 1995, 33,250
shares were granted on October 18, 1995, 12,500 were granted on December 21,
1995, 70,000 were granted in May 1996, 268,500 were granted on November 7, 1996,
and 10,000 were granted on January 10, 1997. In April 1996, 2,500 options
terminated due to termination of employment as of June 1, 1996, 5,000 options
were terminated June 30, 1996 due to termination of employment, and 12,550 were
terminated July 23, 1996 due to termination of employment. As of January 10,
1997, 559,330 options to purchase Class A Common Stock were issued and
outstanding. The Company also has granted options to purchase 30,000 shares of
Class B Common Stock. 5,000 of such options were issued as of August 10, 1995 at
an exercise price of $.01 per share, 3,000 of such options were issued on July
1, 1996 at an exercise price of $.01 per share, 3,000 of such options were
issued on September 12, 1996 at an exercise price of $15.00 per share, 2,000 of
such options were issued on October 1, 1996 at an exercise price of $15.00 per
share, 4,000 of such options were issued on October 3, 1996 at an exercise price
of $15.00 per share, 1,000 of such options were issued on November 5, 1996 at an
exercise price of $15.00 per share, 3,000 of such options were issued on
November 20, 1996 at an exercise price of $15.00 per share, and 9,000 of such
options were issued on January 1, 1997 at an exercise price of $15.00 per share.
 
     Pursuant to the Omnibus Plan, the Company may award shares of Common Stock
to such participants and in such amounts and for such consideration, including
no consideration or such minimum consideration as may be required by law, as it
determines. Restricted shares may be issued pursuant to the Omnibus Plan,
subject to forfeiture if the restrictions do not lapse.
 
     The Company may also grant to any participant who holds an outstanding
stock option the right to surrender such option (to the extent such option is
otherwise exercisable) and to receive from the Company an amount equal to the
excess, if any, of the fair market value of the Class A Common Stock with
respect to which such option is surrendered on the date of such surrender over
the exercise price of the surrendered option.
 
     Unless earlier terminated, the Omnibus Plan will terminate in 2005.
 
     ISSUANCE OF WARRANTS:
 
     On December 1, 1995, the Company issued to Medical Mutual Liability
Insurance Society of Maryland warrants to purchase 88,889 shares of Class A
Common Stock of the Company at an exercise price of $5.625 per share and issued
to each of Stephen Graham, Andrew Hamilton and John Dwyer, a director of the
Company, warrants to purchase 8,000 shares each of Class A Common Stock of the
Company at an exercise price of $11.25 per share.

Joseph Medical Center ("SJMC"), Medical Mutual Liability Insurance Society of
Maryland ("Med Mutual"), Med-Lantic Management Services, Inc., and the Company

governs certain aspects of the Company's management plans and operations. The

Ventures, Inc. ("Genesis") and, at various other times, certain physicians and
other stockholders of the Company executed counterparts of the Stockholders
Agreement.

     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.
 
     Purchasers of Securities hereunder also will be required to execute and
become a party to the Stockholders Agreement or otherwise be subject to
significant contractual restrictions on the resale of such Securities until an
initial public offering for cash of Common Stock.
 
                              CERTAIN TRANSACTIONS
 
     Drs. Rifkin and Kimmel, who are directors, officers and stockholders of the
Company, and Drs. Ancona and Nagel, who are directors of the Company, are
members of the management committee, officers and employees of Baltimore Medical
 
                                       57
 
<PAGE>
Group, LLC. The Company and Baltimore Medical Group, LLC have entered into a PSO
Agreement and a Management Services Agreement pursuant to which Baltimore
Medical Group, LLC has accrued fees of $365,000 payable to the Company in
connection with certain professional management services rendered in 1995 and
the first six months of 1996. Dr. Lamm is the Chairman and an employee of
Cumberland Valley Medical Group, LLC, and an employee and director of the
Company. Dr. Rocha is the Chairman and an employee of Carroll Medical Group, LLC
and is a Director of the Company. Dr. Eig is an employee of Doctors Health
Montgomery LLC and is a Director of the Company.
 
     The Company has agreed that it would consult with Med Mutual and follow Med
Mutual's recommendation regarding the provision of medical malpractice coverage
to Equity Physicians and certain of its other Network Physicians. Such decisions
include, but are not limited to, the selection of the underwriter, the form of
the insurance policy and the premium payment provisions. Med Mutual has agreed
to provide medical malpractice coverage to the Company for premiums consistent
with its rates as approved by the Maryland Insurance Administration. In
addition, Med Mutual will consider alternative insurance programs to meet the
Company's special needs and will request the necessary approvals for such
alternative programs from the Maryland Insurance Administration. This agreement
terminates upon the earlier of a change in control of the Company or termination
of the loan guarantee provided by Med Mutual. If the Company breaches this
agreement, the Company may be required to pay Med Mutual $400,000 and Med Mutual
could require the Company to redeem all or a portion of the Series B Preferred
Stock at the price equal to the greater of the fair market value per share or
the sum of the issue price per share and all accumulated and unpaid interest and
dividends.
 
     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.
 
     Pursuant to Stock Purchase Agreement dated September 4, 1996 (the "Stock
Purchase Agreement"), the Company agreed that it would (i) advise Genesis Health
Ventures, Inc., the Company's Series C Preferred stockholder ("Genesis"), of all
substantive discussions and plans with respect to the delivery of long term
care, pharmacy services, durable medical equipment and home health care services
(the "Services") for the Company, (ii) provide Genesis with all information
needed by Genesis to submit a proposal to provide the Services and (iii) provide
Genesis with an opportunity to provide the Services on commercially reasonable
terms. In addition, the Company has agreed that it will not enter into exclusive
arrangements with third parties that would preclude Genesis from competing to
provide Services to the Company. Genesis and the Company have agreed that
commitments regarding the Services shall not prevent the Company from purchasing
the Services from third parties other than Genesis.
 
     Mr. Dwyer, who was named Executive Vice President, Chief Financial Officer
and Treasurer of the Company in May 1996, and is a Director of the Company, was
previously a principal of Graham, Hamilton & Dwyer ("GHD"), which provides
financial advisory services to the Company. In 1995, GHD received $100,000 for
such services, and in December 1995, the three principals of GHD each received
warrants to purchase 8,000 shares of Class A Common Stock. At that time, Mr.
Dwyer 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.
 
     The Company has entered into acquisition transactions with certain of its
directors who are physicians. These transactions were entered into on
commercially reasonable terms, substantially similar to the terms of its
acquisition transactions with other Equity Physicians, and the consideration
paid in connection with such acquisitions was based on the fair market value of
the medical practice assets or services acquired.
 
     In December 1995, the Company purchased certain assets of the medical
practice of Dr. Rocha, a director of the Company, and four physician partners of
Dr. Rocha. Dr. Rocha was elected to the Board of Directors in May 1996 and was
elected Chairman of Carroll Medical Group, LLC in December 1995. Dr. Rocha and
his four partners received a limited partnership interest in MHLP equivalent to
167,000 shares of Class B Common Stock, valued at $3.00 per share, and a
promissory note with a face value of approximately $138,000 as consideration for
the acquisition.
 
     In May 1996, the Company purchased certain assets of the medical practice
of Dr. Lamm, a director of the Company. Dr. Lamm was elected to the Board of
Directors in May 1996 and was elected Chairman of Cumberland Valley Medical
Group, LLC in May 1996. Dr. Lamm received a limited partnership interest in MHLP
equivalent to 33,000 shares of Class B Common Stock, valued at $3.00 per share,
approximately $34,000 in cash and a promissory note with a face value of
approximately $45,000 as consideration for the acquisition.

     In September 1996, the Company purchased certain assets of the medical
practice of Dr. Eig, a director of the Company. Dr. Eig was elected to the Board
of Directors in May 1996 and as Chairman of Doctor Health Montgomery in
September 1996. Dr. Eig received 16,000 shares of Class B Common Stock and 1,000
options to acquire Class B Common Stock, valued at $7.00 per share, cash in the
amount of $5,000 and a promissory note with a face value of approximately
$38,000 as consideration for the acquisition.
 
     In December 1996, the Company purchased certain assets of the medical
practice of Dr. Graw, a director of the Company since May 1996. In connection
with the acquisition, Dr. Graw's limited liability partnership, which he owns
with five other physicians, received a limited partnership interest in MHLP
equivalent to 74,000 shares of Class B Common Stock, an option to acquire a
limited partnership interest equivalent to 20,000 shares of Class B Common
Stock, exercisable at $15.00 per share, and cash for the practice's collectable
accounts receivable, which will not exceed $625,000. The Company had advanced
$300,000 to Dr. Graw and the practice as an advance against the purchase of the
practice's accounts receivable and received a promissory note from Dr. Graw
evidencing such advance. The promissory note was canceled at the closing of the
acquisition. The Company has delegated to Dr. Graw's practice, and the practice
will perform, certain practice management business functions, which the Company
ordinarily performs for its physicians at its headquarters. The Company
reimburses Dr. Graw's practice for the expenses it incurs in performing the

     In January 1997, the Company entered into an Agreement and Plan of Merger
with Medicap, Inc. ("Medicap"), Medicap Newco, Inc. ("Newco") and Noah
Investments, LLC ("Noah"), pursuant to which Medicap was merged with and into
Newco, a wholly-owned subsidiary of the Company. Medicap was engaged in the
business of seeking business opportunities to place Medicare patients in nursing
homes and similar long term care facilities in Global Capitated Contracts. Noah
was the sole stockholder of Medicap, and the owners of Noah are Alan Rifkin and
certain other persons. Alan Rifkin is the brother of Scott Rifkin, M.D., the
Chairman and an executive officer and a stockholder of the Company. Pursuant to
the Merger Agreement, Noah received 10,000 shares of the Company's Class A
Common Stock and the separate existence of Medicap ceased. In connection with
the merger, the Company also entered into a Consulting Agreement with Alan
Rifkin pursuant to which Mr. Rifkin will advise the Company with respect to the
development of business opportunities for the management of global capitation of
Medicare patients in nursing homes or similar long term facilities and introduce
the Company to potential sources of equity financing and joint venture partners.
Pursuant to the Consulting Agreement, Mr. Rifkin received an option to purchase
10,000 shares of the Company's Class A Common Stock under the Company's Omnibus
Plan. Mr. Rifkin is a Vice President of Newco.

     The following summary description of the capital stock of the Company is
qualified in its entirety by reference to the Company's Articles of Amendment
and Restatement (the "Charter") and Bylaws, copies of which are filed as
exhibits to the Registration Statement of which this Prospectus is a part.
Subject to the rights, privileges and restrictions described below, each issued
and outstanding share of the Common Stock and the Preferred Stock entitles the
holder thereof to one vote on all matters to be voted on by the stockholders of
the Company. There are no preemptive rights or sinking fund provisions with
respect to any of the Company's capital stock.
 
     All shares of the Company's capital stock are subject to significant
restrictions on transfer and will carry a legend to reflect such restrictions.
 
     Except as permitted by the Stockholders Agreement of the Company and the
Charter, the Securities cannot be transferred. The Stockholders Agreement
contemplates that the Company may redeem shares of its stock upon an
"Involuntary Transfer" resulting generally from the insolvency of a stockholder
or upon divorce of an individual stockholder. Voluntary transfers are permitted
only after a stockholder offers its stock, upon the same terms and conditions
contained in the offer it wishes to accept, to all other stockholders on the
terms set out in the Stockholders Agreement. See "Management--Stockholders
Agreement." Individual Stockholders may in certain circumstances make estate
planning transfers for the benefit of themselves or family members on certain
conditions.
 
COMMON STOCK
 
     Except as provided in the Charter, holders of Common Stock are entitled to
one vote per share with respect to all matters submitted to a vote of
stockholders and do not have cumulative voting rights. Subject to preferences
that may be applicable to any outstanding shares of Preferred Stock, holders of
Common Stock are entitled to receive dividends when, as and if declared by the
Board of Directors, out of funds legally available therefor. Upon liquidation,
dissolution or winding up of the Company, holders of Common Stock are entitled
to share ratably in assets available for distribution after payment of all debts
and other liabilities and subject to the prior rights of any holders of any
preferred stock then outstanding.
 
CLASS A COMMON STOCK
 
     The holders of the Class A Common Stock are entitled to elect five of the
18 directors of the Company (each a "Class A Director"). The affirmative vote of
a majority of the stock of Class A Common Stock represented at a meeting at
which a quorum is present is sufficient to approve any matter with respect to
which such holders are entitled to vote; provided, that 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
 
                                       62
 
<PAGE>
"Converted Series B Class C Director"). Upon the conversion of all of the Series
C Preferred Stock then outstanding into shares of Class C Common Stock, the
holders of such Class C Common Stock into which such Series C Preferred Stock
has been converted, voting as a single sub-class ("the Series C Subclass"),
shall, prior to the Company's 1998 annual meeting of stockholders, be entitled
to elect one of the 18 directors of the Company. After the Company's 1998 annual
meeting of stockholders, the Company shall have 19 directors, and the Series C
Subclass shall be entitled to elect two directors of the Company (each a
"Converted Series C Class C Director"). Except with respect to the election of
Directors, the affirmative vote of a majority of the stock of Class C Common
Stock represented at a meeting at which a quorum is present is sufficient to
approve any matter with respect to which such holders are entitled to vote;
provided, that the affirmative vote of a plurality of all votes cast by such
Series A Subclass, Series B Subclass, or Series C Subclass, as the case may be,
shall be sufficient to elect a Converted Series A Class C, Converted Series B
Class C Director, or Converted Series C Class C Director, respectively. The
Series A Subclass, the Series B Subclass, or the Series C Subclass, as the case
may be, at any annual meeting or upon a special meeting called by the holders of
not less than 25% of the shares of such subclass outstanding may remove the
Converted Series A Class C, Converted Series B Class C, or Converted Series C
Class C Director, respectively, by the affirmative vote of 80% of all of the
votes entitled to be cast for such director.
 
     The Charter of the Company includes a provision pursuant to which, upon
completion of a "Qualified" or "Non-Qualified" Public Offering, each share of
the Company's Class A Common Stock, Class B Common Stock, and Class C Common
Stock shall be converted, without any action on the part of the stockholder or
the Company, into an identical share of the Company's Class A Common Stock, and
all special rights granted to the holders of Class A, Class B, and Class C
Common Stock and to all holders of Series A, Series B and Series C Preferred
Stock shall cease and terminate.
 
SERIES A, SERIES B AND SERIES C PREFERRED STOCK
 
     VOTING RIGHTS. Except with respect to the election and removal of
directors, every holder of Series A Preferred Stock, Series B Preferred Stock,
and Series C Preferred Stock shall be entitled to cast that number of votes
equal to the full number of shares of Class C Common Stock into which such
holder's Preferred Stock is then convertible.
 
     SERIES A DIRECTORS. The holders of Series A Preferred Stock voting as a
single class, are entitled to elect two directors (each, a "Series A Director").
The affirmative vote of a majority of the shares of Series A Preferred Stock
represented at a meeting at which a quorum is present is sufficient to approve
any matter with respect to which such holders are entitled to vote; provided,
that the affirmative vote of a plurality of all votes cast shall be sufficient
to elect Series A Directors. The holders of Series A Preferred Stock, at any
annual meeting or upon a special meeting called by the holders of not less than
25% of the shares of Series A Preferred Stock then outstanding, may remove any
Series A Director by the affirmative vote of at least 80% of all of the votes
entitled to be cast for such Series A Director.
 
     SERIES B DIRECTORS. The holders of Series B Preferred Stock, voting as a
single class, are entitled to elect two directors (each, a "Series B Director").
The affirmative vote of a majority of the shares of Series B Preferred Stock
represented at a meeting at which a quorum is present is sufficient to approve
any matter with respect to which such holders are entitled to vote; provided,
that the affirmative vote of a plurality of all votes cast shall be sufficient
to elect Series B Directors. The holders of Series B Preferred Stock, at any
annual meeting or upon a special meeting called by the holders of not less than
25% of the shares of Series B Preferred Stock then outstanding, may remove any
Series B Director by the affirmative vote of at least 80% of all of the votes
entitled to be cast for such Series B Director.
 
     SERIES C DIRECTORS. The holders of Series C Preferred Stock, voting as a
single class, are entitled to elect one director until the Company's 1998 annual
meeting of stockholders and thereafter, shall be entitled to elect two directors
(each, a "Series C Director"). The affirmative vote of a majority of the shares
of Series C Preferred Stock represented at a meeting at which a quorum is
present is sufficient to approve any matter with respect to which such holders
are entitled to vote; provided, that the affirmative vote of a plurality of all
votes cast shall be sufficient to elect Series C Directors. The holders of
Series C Preferred Stock, at any annual meeting or upon a special meeting called
by the holders of not less than 25% of the shares of Series C Preferred Stock
then outstanding, may remove any Series C Director by the affirmative vote of at
least 80% of all of the votes entitled to be cast for such Series C Director.
 
   
     SPECIAL DIRECTOR APPROVAL REQUIREMENT. Pursuant to the Charter, the Company
is generally prohibited from taking certain actions without the separate
affirmative vote of each of the Series A Directors, Series B Directors, and
Series C Directors including (i) the incurrence of certain indebtedness, (ii)
amendments of the Charter or By-Laws that adversely affect the holders of Series
A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock, as the
case may be, or Class C Common Stock (including the issuance of senior stock),
(iii) with respect to the Series A and Series B Directors, amendments to any of
the employment agreements between the Company and a Management Stockholder, or
(iv) with
    
 
                                       63
 
<PAGE>
respect to the Series C Directors, pay any dividend on the Series A or Series B
Preferred Stock prior to September 1, 1998 unless paid in connection with a
redemption.
 
     SPECIAL PREFERRED STOCKHOLDER APPROVAL REQUIREMENT. Pursuant to the
Charter, the Company is generally prohibited from taking certain actions (each a
"Preferred Stockholder Major Decision") without the separate affirmative vote of
a majority of the shares of Series A Preferred Stock and Series B Preferred
Stock, represented at a meeting, including (i) the adoption of any business plan
of the Company, (ii) the issuance of shares or rights to acquire shares to
employees of the Company which, when aggregated with all other such issuances,
exceeds 10% of the fully diluted shares of capital stock of the Company
(provided; that shares of Class A Common Stock and rights to acquire such shares
issued to the Management Stockholders and other executive employees in amounts
not to exceed 25% of the fully diluted shares of capital stock of the Company as
of December 1, 1995 shall not be counted toward such 10% limitation), (iii) the
issuance of shares of capital stock to any person or entity which has legitimate
business interests that are materially adverse to the holders of Series A
Preferred Stock or the Series B Preferred Stock, as the case may be, (iv) any
sale or other disposition of all or any substantial portion of its assets, or
(v) certain mergers or consolidations of the Company, (vi) any underwritten
public offering other than an offering which is based upon a total market
capitalization of the Company, at the time of such offering, of at least $25
million and from which the Company receives net proceeds of not less than $15
million. Additionally, the separate vote of the holders of Series A Preferred
Stock is required for any optional redemption of the Series B Preferred Stock,
unless the Company has previously redeemed the Series A Preferred Stock. The
Charter provides that notwithstanding the failure to obtain the approval of such
Preferred Stockholder Major Decisions, the Company may nonetheless take such
actions; provided that the Company provide advance written notice of the action
and subject to the right of the holders of each Series of Preferred Stock to
require the Company to redeem all of each such Series in accordance with the
terms of the Charter.
 
   
     REDEMPTION. The Series A Preferred Stock, the Series B Preferred Stock and
the Series C Preferred Stock must be redeemed by the Company (unless such right
is waived in writing by the holder of Preferred Stock), or may be redeemed at
the request of the holders of Preferred Stock, in a number of different
circumstances, including: (i) Upon the request of holders of the Series A and
Series B Preferred Stock between March 1, 2000 and June 1, 2000, the Company
must redeem all such stock held by holders requesting redemption; (ii) sale of
all or substantially all of the assets of the Company; (iii) the filing by the
Company of a voluntary or involuntary petition in bankruptcy, unless dismissed
within certain prescribed time periods; (iv) 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; (v) the entry of a
material judgment against the Company, which is not dismissed, stayed, or fully
bonded within 60 days; (vi) the failure by the Company to pay any amount due to
the holders of the Preferred Stock when due; (vii) 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; (viii) with respect to the Series C
Preferred Stock, upon an initial public offering of the Company's equity
securities; and (ix) certain other events, including changes of control of
various types. No redemption of the Series B Preferred Stock may occur until all
of the Series A Preferred Stock is redeemed and the full redemption price has
been paid. No redemption of the Series C Preferred Stock may occur until all of
the Series A Preferred Stock and the Series B Preferred Stock is redeemed and
the full redemption price has been paid.
    
 
     CONVERSION. All, but not less than all, of the shares of the Series A and
Series B Preferred Stock are convertible, one share for one share (subject to
increase if the Company issues shares at a dilutive price), into shares of Class
C Common Stock at the option of holders of the Series A and Series B Preferred
Stock at any time prior to 5:00 p.m. (EST) on February 24, 2000. However,
holders of the Series A Preferred Stock who have not made full payment in cash
to the Company for the shares of Series A Preferred Stock may not convert their
shares. All, but not less than all, of the shares of Series C Preferred Stock
are convertible, one share for one share (subject to increase if the Company
issues shares at a dilutive price), into shares of Class C Common Stock at the
option of holders of the Series C Preferred Stock at any time. Shares of
Preferred Stock will automatically be converted (unless redeemed), one share for
one share (subject to dilution adjustments), into shares of Class C Common Stock
upon the occurrence of a combination, consolidation or merger transaction
involving the Company in which the Company is not the survivor, the sale,
exchange or other disposition of all, or substantially all, of the Company's
assets, and upon the consummation of any public offering of securities of the
Company.
 
     The special voting and approval rights of the holders of the Preferred
Stock and their rights to require the redemption of the Preferred Stock or to
convert such Preferred Stock into Class C Common Stock may prevent the Company
from consummating one or more transactions, including equity and debt financings
that could be beneficial to the Company's stockholders.
 
                                       64

     DIVIDENDS. Prior to April 1, 2000, cash dividends at the rate of $0.325 per
share per annum accrue on the Series A Preferred Stock. Such dividends are
cumulative and will accrue, whether or not earned or declared or payment is
legally available, from and after the 24th day of February, 1995 and bear
interest on accrued but unpaid amounts at the rate of 6.5% per annum, compounded
quarterly. Such accrued dividends and interest are payable only upon the
liquidation of the Company or the redemption or conversion of the Series A
Preferred Stock and if not paid prior to April 1, 2000, the amount of such
accrued but unpaid dividends and interest payments will become an unsecured
obligation of the Company. On or after April 1, 2000, holders of the Series A
Preferred Stock are entitled to receive, when and as declared by the directors
of the Company and when legally available, cash dividends at the per annum rate
of 100 basis points over the Wall Street Journal Prime Rate as of the last
business day prior to April 1, 2000 based on the original issue price of the
Series A Preferred Stock. So long as any shares of Series A Preferred Stock are
issued and outstanding, no dividends may be declared and no other distribution
may be made, with certain exceptions, with respect to any other class or series
of stock or equity interest of the Company without the consent of each director
elected by the holders of the Series A Preferred Stock.
 
     Prior to April 1, 2000, cash dividends at the rate of $1.097 per share per
annum accrue on the Series B Preferred Stock. Such dividends are cumulative and
will accrue, whether or not earned or declared or payment is legally available,
from and after the first day of December, 1995 and bear interest on accrued but
unpaid amounts at the rate of 9.75% per annum, compounded quarterly. Such
dividends and interest are payable only after all dividends and interest accrued
on or with respect to the Series A Preferred Stock have been paid and only upon
the liquidation of the Company or the redemption or conversion of the Series B
Preferred Stock and if not paid prior to April 1, 2000, the amount of such
accrued but unpaid dividends and interest payments will become an unsecured
obligation of the Company. On and after April 1, 2000, holders of the Series B
Preferred Stock are entitled to receive, when and as declared by the directors
of the Company and when legally available, cash dividends at the per annum rate
of 100 basis points over the Wall Street Journal Prime Rate as of the last
business day prior to April 1, 2000 based upon the original issue price of the
Series B Preferred Stock.
 
     Cash dividends at the rate of $1.40 per share per annum accrue on the
issued and outstanding Series C Preferred Stock and cash dividends at the rate
of $1.60 per share per annum shall accrue on shares to be issued pursuant to the
Option Agreement with Genesis. Such dividends are cumulative and will accrue,
whether or not earned or declared or payment is legally available, from and
after September 4, 1996 and bear interest on accrued but unpaid amounts at the
rate of 8.00% per annum. Such dividends and interest are payable only after all
dividends and interest accrued on or with respect to the Series A and Series B
Preferred Stock have been paid and only upon the liquidation of the Company or
the redemption or conversion of the Series C Preferred Stock and if not paid,
the amount of such accrued but unpaid dividends and interest payments will
become an unsecured obligation of the Company, bearing interest at the per annum
rate of 100 basis points over the Wall Street Journal Prime Rate as of the last
business day prior to such liquidation, redemption or conversion. All accrued
dividends and unpaid interest on the Series C Preferred Stock shall be canceled
and no longer be payable in the event the Company consummates a Qualified Public
Offering on or before August 30, 1998 at a price per share of not less than the
weighted average price paid or to be paid by the holders of Series C Preferred
Stock for all shares of Series C Preferred Stock then outstanding or subject to
the Option, plus all accrued but unpaid dividends and interest thereon. So long
as any shares of Series C Preferred Stock remain outstanding, no dividends shall
be declared or paid upon, nor shall any dividend or other distribution be made
with respect to, any shares or any other class or series of stock or equity
interest of the Company other than the Series A Preferred Stock or Series B
Preferred Stock without the consent of the Series C Preferred Director or
Directors.
 
     The Company may not issue any shares of capital stock which are senior in
dividend and/or liquidation rights to the Preferred Stock, and the Preferred
Stockholders have certain anti-dilution rights with respect to most issuances of
capital stock by the Company which are junior to the Preferred Stock and which
are issued for a share price less than the original per share price of the
Preferred Stock.
 
     LIQUIDATION RIGHTS. Upon liquidation of the Company, holders of the Series
A Preferred Stock, if any, are entitled to receive a liquidating distribution
equal to the greater of (i) the sum of the fair market value per share of the
Series A Preferred Stock plus all accrued but unpaid dividends thereon, or (ii)
the sum of the original purchase price per share of the Series A Preferred Stock
plus all accrued but unpaid dividends thereon. After payment of such
preferential amount to the holders of the Series A Preferred Stock, holders of
the Series B Preferred Stock, if any, are entitled to receive a liquidating
distribution equal to the greater of (i) the sum of the fair market value per
share of the Series B Preferred Stock plus all accrued but unpaid dividends
thereon, or (ii) the sum of the original purchase price per share of the
Preferred Stock plus all accrued but unpaid dividends thereon. After payment of
such preferential amount to the holders of the Series A and Series B Preferred
Stock, holders of the Series C Preferred Stock, if any, are entitled to receive
a liquidating distribution in the amount of $17.50 per share of Series C
Preferred Stock issued pursuant to the Stock Purchase Agreement which is then
outstanding and $20.00
 
                                       65
 
<PAGE>
per share of Series C Preferred Stock issued pursuant to the Option Agreement
which is then outstanding, plus all accrued but unpaid dividends and interest
thereon. After payment of the preferential liquidation amounts to the holders of
Series A, Series B and Series C Preferred Stock, each share of Common Stock is
entitled to share ratably with all other shares of Common Stock in the remaining
net assets of the Company upon liquidation.
 
PERMITTED REDEMPTIONS
 
     The Charter provides that the Company may effect the following redemptions
without the consent or approval of any of the Series A Preferred Directors, the
Series B Preferred Directors, the Series C Preferred Directors, the holders of
Series A Preferred Stock, the holders of Series B Preferred Stock and the
holders of Series C Preferred Stock:
 
           (i) upon the payment in full of all accumulated and unpaid accrued
               dividends and interest on all outstanding shares of 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, except that such redemptions may be made
               without payment of accrued dividends and interest on outstanding
               shares of Series C Preferred Stock if the Company completes a
               Qualified Public Offering of its securities prior to August 30,
               1998;
 
           (ii) redemptions of shares of Class A Common Stock owned by any
                employee (other than a Management Stockholder) when and as
                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;
 
           (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; or
 
          (vii) certain redemptions of Series C 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 and Series
                B 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 Class B Common Stock
covered by the Registration Statement and offered by this Prospectus and any
accompanying Prospectus Supplement and may be attached to or separate from such
Class B Common Stock. With respect to each offering of Options, a separate
agreement (each, an "Option Agreement") will be entered into between the Company
and the holder of such Options. Except with respect to the number of Options to
be issued and the exercise price in any particular offering, the terms of the
Options as set forth in this Prospectus will not vary from offering to offering.
 
     The applicable Prospectus Supplement will describe certain details as to
each offering of such Options, including the following where applicable: (i) the
offering price; (ii) the number of Options being offered; and (iii) certain
federal income tax consequences.
 
     The Options will be issued pursuant to an Option Agreement, between the
Company and the holder of such Option. None of the Options have been issued
prior to the date of this Prospectus. The following discussion of the material
terms and provisions of the Options is qualified in its entirety by reference to
the detailed provisions of the Option Agreement, the form of which has been
filed as an exhibit to the Registration Statement on Form S-1 of which this
Prospectus forms a part.
 
                                       66
 
<PAGE>
     Each Option will entitle the holder to purchase, at any time until the
tenth anniversary of the date of the Option Agreement, one share of Class B
Common Stock at an exercise price set forth in the Option Agreement. The Options
may be exercised in whole or in part. Unless exercised, the Options will
automatically expire on the tenth anniversary of the date of this Prospectus.
 
     For a holder to exercise the Options, there must be a current registration
statement in effect with the Commission and qualification with or approval from
various state securities agencies with respect to the shares of Class B Common
Stock underlying the Options, or an opinion of counsel for the Company that
there is an effective exemption from registration. As long as the Options remain
outstanding and exercisable, the Company will use its reasonable efforts to
maintain the effectiveness of such registration statement. There can be no
assurance, however, that the effectiveness of such registration statement can be
maintained. If a registration statement covering such shares of Class B Common
Stock is not kept current for any reason, or if the shares underlying the
Options are not registered in the state in which a holder resides, the Options
will not be exercisable unless there is an exemption from applicable
registration requirements. See "Risk Factors--Federal and State Registration
Requirements; Possible Inability to Exercise Options."
 
     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, unexercised
Options will become void.
 
     Options may be exercised by delivering to the Company payment, as provided
in the applicable Option Agreement, 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 necessary notice 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 are exercised, a new option agreement will be executed for the
remaining amount of Options.
 
     AMENDMENTS AND SUPPLEMENTS TO OPTION AGREEMENTS.
 
     Each Option Agreement may be amended or supplemented without the consent of
the holders of the Options issued thereunder to effect changes that are not
inconsistent with the provisions of the Options and that do not adversely affect
the interests of the holders of the Options.
 
     OPTION ADJUSTMENTS.
 
     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) in the event that any change is made to the Class B Common Stock (whether by
reason of a recapitalization or stock dividend, stock split or other change in
capital structure); or (ii) in the event of a merger or other business
combination; or (iii) the distribution to all holders of Common Stock of
evidences of indebtedness or assets of the Company.
 
     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.
 
                              PLAN OF DISTRIBUTION
 
     Securities may be issued from time to time in connection with the
affiliation of medical practices with the Company. Except in connection with the
exercise of the Options, the Company will not receive cash proceeds from the
issuance of the Securities. Securities may be issued by the Company as
consideration in one or a combination of the following types of transactions:
(i) as consideration for acquisitions of certain assets of medical practices;
(ii) as consideration pursuant to IPA participation agreements; or (iii) as
compensation pursuant to employment arrangements between the physician and a
Core Medical Group or between the Company and certain employees. A Prospectus
Supplement will set forth certain details as to the offering of the Securities
offered thereby. Such details will comprise, to the extent applicable (1) in the
case of Options, the Class B Common Stock for which each such Option is
exercisable, and the exercise price; and (2) in the case of any offering of
Securities, to the extent applicable, the offering price, and certain Federal
income tax consequences. With respect
 
                                       67
 
<PAGE>
to offerings of Securities in connection with the acquisition of certain assets
of medical practices, a Prospectus Supplement will be provided which will
contain information about the specific transaction and the particular medical
practice involved in the transaction. The terms of the securities as set forth
in this Prospectus will not change. It is not expected that underwriting
discounts or commissions will be paid by the Company.
 
     The value of the Class B Common Stock will be determined by the Company's
management and Board of Directors based upon the Company's results of operations
and current financial condition, recent sales of the Company's securities and
arms' length negotiations with potential purchasers, estimates of the business
potential and prospects of the Company, the economics of the health care
industry in general, the general condition of the equity securities market in
general and other relevant factors.
 
     The Securities issued hereunder will be new issues of securities with no
established trading market. The Company does not currently intend to apply for
the listing of any Securities on any national securities exchange. No assurance
can be given as to the liquidity of the trading market for any such Securities.
The Securities offered hereby will be subject to certain contractual
restrictions on resale, including the Stockholders Agreement. See "Description
of Capital Stock", "Risk Factor--Voting Limitations; Restrictions on Resale of
Securities" and "--Absence of Public Market" and "--Penny Stock Rules."
 
     ACQUISITION OF CERTAIN ASSETS OF MEDICAL PRACTICES.
 
     It is anticipated that the acquisitions of the medical practices will
involve the receipt by the Company of substantially all of the business of such
medical practices (primarily enumerated tangible assets of such practices and
related contractual rights). The terms of an acquisition of a medical practice
are determined by negotiations between the Company's representatives and
physicians. Factors taken into account in such transactions with respect to the
amount of Securities to be issued in such transactions include the established
size, quality and reputation of the practice and the Company's estimate of the
value of the Securities. It is anticipated that shares of Class B Common Stock
issued in any such acquisitions will, in most cases, be valued at a price
reasonably related to the current value of the Class B Common Stock, either at
the time that the terms of the affiliation agreement are tentatively agreed
upon, or at or about the time of closing, or during the period or periods prior
to delivery of the Securities.
 
     CONTRACTUAL ARRANGEMENTS--IPA ARRANGEMENTS.
 
     It is anticipated that the entry by the Company into IPA arrangements will
involve the agreement by a medical practice to authorize the Company to
negotiate service contracts on its behalf. See "BUSINESS--Development of
Integrated Health Care Delivery System--Independent Physicians Associations."
The terms of an IPA arrangement are determined by negotiations between the
Company's representatives and physicians. Factors taken into account in such
transactions with respect to the amount of Securities to be issued in such
transactions include the commercial terms of the particular IPA arrangement, the
established size, quality and reputation of the practice and the Company's
estimate of the value of the Class B Common Stock. It is anticipated that shares
of Class B Common Stock issued in any such IPA arrangements will, in most cases,
be valued at a price reasonably related to the current value of the Class B
Common Stock, either at the time that the terms of the IPA arrangement are
tentatively agreed upon, or at or about the time of closing, or during the
period or periods prior to delivery of the Securities.
 
     CONTRACTUAL ARRANGEMENTS--EMPLOYMENT ARRANGEMENTS
 
     It is anticipated that the entry by the Core Medical Groups into employment
arrangements with physicians will involve the agreement by the physician to
furnish services to a Core Medical Group including the provision of medical
services pursuant to the Company's Managed Care Contracts. See
"BUSINESS--Development of Integrated Health Care Delivery System--Employment of
Physicians by the Core Medical Group." Pursuant to the Company's management of
the Core Medical Groups under the PSO Agreements, the terms of an employment
arrangement are determined by negotiations between the Company's representatives
and physicians. Factors taken into account in such transactions with respect to
the amount of Securities to be issued in such transactions include the
commercial terms of the particular employment arrangement, the established size,
quality and reputation of the practice of the employee and the Company's
estimate of the value of the Class B Common Stock. It is anticipated that shares
of Class B Common Stock issued in any such employment arrangements will, in most
cases, be valued at a price reasonably related to the current value of the Class
B Common Stock, either at the time that the terms of the employment arrangements
are tentatively agreed upon, or at or about the time of closing, or during the
period or periods prior to delivery of the shares.
 
                                       68
 
<PAGE>
     It is anticipated that the entry by the Company into employment
arrangements with employees will involve the agreement by the employee to
furnish services to the Company including with respect to the recruitment of
physicians to enter into contractual relationships with the Company. Factors
taken into account with respect to such transactions include the commercial
terms of the particular employment arrangements and the Company's estimate of
the value of the Class B Common Stock. It is anticipated that shares of Class B
Common Stock issued in any such employment arrangement will be valued at a price
reasonably related to the current value of the Class B Common Stock, either at
the time that the terms of the employment arrangements are tentatively agreed
upon or at the time of closing or during the period or periods prior to delivery
of the shares.
 
                           SHARES ELIGIBLE FOR RESALE
 
     Although there is no public market for the Securities and it is not
anticipated that a public market will develop in the near future, sales of
substantial shares of the Company's capital stock could adversely affect the
price at which the Securities could be resold and could impair the Company's
future ability to raise capital through an offering of its equity securities.
 
     All of the Class B Common Stock issued pursuant to this Prospectus or
issued upon exercise of Options granted pursuant to this Prospectus will be
subject to significant restrictions on transfer pursuant to the Stockholders
Agreement to which each person acquiring shares will be a party. Additionally,
the Options will be non-transferable except in the case of death. Without such
contractual restrictions, however, such Securities would be freely transferable
without restriction or registration under the Securities Act, except for any
shares purchased by an existing "affiliate" of the Company as that term is
defined under the Securities Act (an "Affiliate"), which Securities would be
subject to the resale limitations of Rule 144 adopted under the Securities Act.
 
     As of January 10, 1997, there were 810,000 shares of Class A Common Stock
and 2,593,000 shares of Class B Common Stock issued and outstanding. In
addition, up to 672,219 shares of Class A Common Stock, 30,000 shares of Class B
Common Stock and 1,926,984 shares of Class C Common Stock are issuable upon the
exercise or conversion of options, warrants or Preferred Stock. Securities
previously acquired were issued by the Company in private transactions not
involving a public offering and are "restricted securities" for purposes of Rule
144 adopted under the Securities Act. In addition to the contractual limitations
set forth in the Stockholders Agreement, such securities may not be resold in a
public distribution, except in compliance with the registration requirements of
the Securities Act, pursuant to a valid exemption therefrom or pursuant to Rule
144.
 
     In general, under Rule 144 as currently in effect, beginning 90 days after
the effective date of the Registration Statement, a person (or persons whose
shares are aggregated) who has beneficially owned Securities which are
restricted securities for at least two years (including the holding period of
any prior owner except an affiliate of the Company) would be entitled to sell
within any three-month period a number of shares that does not exceed the
greater of: (i) one percent of the number of Securities then outstanding; or
(ii) the average weekly trading volume of the Securities during the four
calendar weeks preceding such sale, subject to the filing of a Form 144 with
respect to such sale. Sales under Rule 144 are also subject to certain manner of
sale provisions and notice requirements and to the availability of current
public information about the Company. Under Rule 144(k), a person who is not
deemed to have been an Affiliate at any time during the 90 days immediately
preceding a sale, and who has beneficially owned the Securities proposed to be
sold for at least three years (including the holding period of any prior owner
except an Affiliate), is entitled to sell such Securities without complying with
the manner of sale, public information, volume limitation or notice provisions
of Rule 144. Persons deemed to be Affiliates desiring to sell shares to the
public generally must always sell pursuant to the conditions of Rule 144, even
after the applicable holding periods have been satisfied.
 
     The Commission has recently proposed amendments to Rule 144 that would
permit resales of restricted securities after a one-year, rather than a two-year
holding period, subject to compliance with the other provisions of Rule 144, and
would permit resale of restricted securities by non-Affiliates under Rule 144(k)
after a two-year, rather than a three-year holding period. If adopted, such
amendments could result in resales of restricted securities sooner than would be
the case under Rule 144 as currently in effect.
 
     Ninety days after the effective date of the Registration Statement, 800,000
shares of the outstanding Class A Common Stock will be available for resale in
compliance with all of the conditions of Rule 144. The remaining 10,000 shares
of Class A Common Stock outstanding may be resold in compliance with all of the
conditions of Rule 144 in January 1999. In February 1997, 2,200,000 shares of
the outstanding Class B Common Stock will be available for resale in compliance
with all of the conditions of Rule 144. The remaining 393,000 shares of Class B
Common Stock outstanding may be resold at
 
                                       69
 
<PAGE>
various times from January 1998 through January 1999 in compliance with all of
the conditions of Rule 144. The 1,000,000 outstanding shares of Series A
Preferred Stock (or the shares of Class C Common Stock acquired upon conversion
of those shares) will be available for resale in compliance with all of the
conditions of Rule 144 in February 1997. The 355,556 outstanding shares of
Series B Preferred Stock (or the shares of Class C Common Stock acquired upon
conversion of those shares) will be available for resale pursuant to all of the
conditions of Rule 144 in December 1997. 428,571 shares of Series C Preferred
Stock (or the shares of Class C Common Stock acquired upon conversion of those
shares) will be available for resale, in compliance with all of the conditions
of Rule 144, in September 1998 and 142,857 shares of Series C Preferred Stock
(or the shares of Class C Common Stock acquired upon conversion of those shares)
will be available for resale, in compliance with all of the conditions of Rule
144, in January 1999.
 
     The 112,889 shares of Class A Common Stock issuable upon exercise of
outstanding warrants will also be deemed restricted securities. Depending on the
method of exercise, such shares may be available for resale in December 1997 or
two years from the date of exercise, subject to all of the conditions of Rule
144.
 
     Subject to certain limitations, Rule 701 promulgated under the Securities
Act modifies the conditions of Rule 144 with respect to the resale of securities
originally purchased from the Company by its employees, directors, officers,
consultants or advisors prior to the date the issuer becomes subject to the
reporting requirements of the Exchange Act pursuant to written compensatory
benefit plans or written contracts relating to the compensation of such persons.
The Commission has indicated that Rule 701 will apply to typical stock options
granted by an issuer before it becomes subject to the reporting requirements of
the Exchange Act, along with the shares acquired upon exercise of such options
(including exercises after the date of this Prospectus). Securities issued in
reliance on Rule 701 are restricted securities and, subject to the contractual
restrictions of the Stockholders Agreement, may be resold 90 days after the
effective date of the Registration Statement by persons other than Affiliates
subject only to the manner of sale provisions of Rule 144 and by Affiliates
under Rule 144 without compliance with its two-year minimum holding period
requirements.
 
   
     As of January 10, 1997, options to purchase 559,330 shares of Class A
Common Stock have been issued and are outstanding, of which options to purchase
approximately 112,080 shares are vested and exercisable. Of the remaining
outstanding options, options to acquire 208,000, 10,750, 223,500, and 5,000
shares of Class A Common Stock are exercisable in 1997, 2000, 2001 and 2003,
respectively. Shares of common stock issued upon exercise of Class A options may
be resold 90 days after the effective date of the Registration Statement by
persons other than Affiliates subject only to the manner of sale provisions of
Rule 144 and by Affiliates without compliance with its two-year minimum holding
period requirements. 5,000 16,000, and 9,000 shares of Class B Common Stock to
be issued upon the exercise of Class B options, may be resold, depending on the
method of exercise, in 1997, 1998 and 1999, respectively, pursuant to the
provisions of Rule 144.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

BOARD OF DIRECTORS AND STOCKHOLDERS
DOCTORS HEALTH SYSTEM, INC.

     We have audited the accompanying restated consolidated balance sheets of
Doctors Health System, Inc. (a Maryland corporation), as of June 30, 1996 and
1995, and the related restated consolidated statements of operations,
stockholders' equity, and cash flows for the year ended June 30, 1996 and for
the period February 24, 1995 (date of inception) to June 30, 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 audits.

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

     In our opinion, the restated financial statements referred to above,
present fairly, in all material respects, the consolidated financial position of
Doctors Health System, Inc. as of June 30, 1996 and 1995, and the consolidated
results of its operations and its cash flows for the year ended June 30, 1996
and for the period February 24, 1995 (date of inception) to June 30, 1995, in
conformity with generally accepted accounting principles.

     We have also audited Schedule II--Valuation and Qualifying Accounts for the
year ended June 30, 1996 and the period February 24, 1995 (date of inception) to
June 30, 1995. In our opinion, this schedule presents fairly, in all material
respects, the information required to be set forth therein.

     A summary of the significant accounting policies consistently applied in
the preparation of the accompanying consolidated financial statements follows.
 
     RESTATEMENT OF FINANCIAL STATEMENTS
 
     The Company previously prepared its consolidated financial statements
including the asset, liability and results of operations of certain affiliates
with which the Company entered into long-term management contracts.
Notwithstanding the financial, administrative and other relationships that exist
between the Company and the affiliates, management has determined that its
business is effectively a health care management company. Accordingly these
financial statements have been restated to give effect to this change and the
assets, liabilities and results of operations of affiliates are no longer
consolidated. The Company has reclassified the Redeemable Class A Common Stock
in the accompanying financial statements--See Note 20.
 
     BASIS OF PRESENTATION/PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements have been prepared on the accrual
basis of accounting and include the accounts of the Company and its
subsidiaries. The Company has adopted a June 30th year end. All significant
intercompany accounts and transactions have been eliminated in the
consolidation.

NOTE 1--BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--CONTINUED
     NET REVENUE RECOGNITION
 
     The Company's net revenues represent contractual management and similar
fees earned under its long-term PSO Agreements with Core Medical Groups. Under
the PSO Agreements, the Company is contractually responsible and at risk for the
operating costs of the Core Medical Groups, with the exception of amounts
retained by physicians. The Company's net revenues include the reimbursement of
all medical practice operating costs and the contractual management fees due as
defined and stipulated in the PSO Agreements. Contractual fees are recognized
when collection is probable. (See Note 3)
 
     CAPITATION REVENUE AND MEDICAL SERVICES EXPENSE RECOGNITION
 
     The Company has three global capitated contracts and ten gatekeeper
capitation contracts with eleven HMOs. Under the contracts, the Company receives
monthly capitation fees based on the number of enrollees electing any one of the
Company's affiliated primary care physicians. The capitation revenue under these
contracts is prepaid monthly based on the number of enrollees and is recognized
as capitation revenue during the month services are provided to the enrollees.
During the year ended June 30, 1996, approximately $382,000 and $307,000, were
recorded as global capitation and gatekeeper capitation revenue, respectively,
in the Company's financial statements. During the period ended June 30, 1995,
the Company had no global or gatekeeper capitation contracts.
 
     The Company's commercial capitation contract also includes a provision
whereby the Company can earn additional incentive revenue or incur medical
services expenses based upon the enrollees' utilization of hospital services.
Estimated amounts receivable or payable from the HMO are recorded based upon
actual hospital utilization and associated costs incurred by assigned HMO
enrollees, compared to the portion of the Commercial capitation fees allocated
for hospitalization. Differences between actual contract settlements and
estimated receivables or payables relating to the arrangement are recorded in
the year of settlement. Included in accrued medical services as of June 30, 1996
is approximately $68,000 of estimated amounts due to the HMO under this
arrangement. Also, as of June 30, 1996, the Company has included in accrued
medical services a provision of approximately $77,000 which represents an
estimate of the loss to be incurred over the remaining term of the commercial
capitation contract. Under the Company's two Medicare full risk capitation
contracts, the Company has assumed responsibility for managing and paying for
substantially all of the medical care for the respective payors' enrollees.
 
     The Company is responsible for some or all of the medical services provided
by its affiliated physicians and other providers to which it refers patients who
are covered under global capitated contracts. The cost of medical services is
recognized in the period in which it is provided and includes an estimate of the
cost of services which have been incurred but not yet reported. The estimate for
accrued medical services is based on projections of costs using historical
studies of claims paid. Estimates are continually monitored and reviewed and, as
settlements are made or estimates are adjusted, differences are reflected in
current operations. As of June 30, 1996, approximately $400,000 was recorded as
accrued medical services for incurred but not reported services.
 
     The Company purchases insurance from independent insurance companies which
limits the amount of risk it ultimately bears by providing reimbursement
payments once medical services provided to an individual enrollee exceed an
agreed-upon amount. Under the Commercial capitation contract, the Company is
insured for 90% of all medical services expense over $5,000 per enrollee per
year. Under the Medicare full risk capitation contracts, the Company is insured
for 90% of all physician and hospital medical services expense over $5,000 and
$75,000, respectively, per enrollee per year. Estimates of insurance recoveries
as of June 30, 1996 under this arrangement were approximately $23,000.
 
     CASH AND CASH EQUIVALENTS
 
     The Company considers all highly liquid investments with original
maturities of three months or less when purchased to be cash equivalents.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--CONTINUED
 
NOTE 1--BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--CONTINUED
     ACCOUNTS RECEIVABLE
 
     Accounts receivable principally represent receivables from third party
payors and patients for patient medical services provided by affiliated CMG's.
The accounts receivable have been assigned to the Company under the terms of the
PSO agreements. Such amounts are recorded net of contractual allowances and
estimated bad debts.
 
     ACCOUNTS RECEIVABLE--AFFILIATES
 
     Accounts receivable--affiliates include amounts due from the CMG for
Medicare and Medicaid services provided in respect of which the Company has
legal rights to the proceeds. As of June 30, 1995 and 1996, $215,437 and
$1,208,685, respectively represented such amounts.
 
     MEDICAL SUPPLIES
 
     The Company expenses the cost of routine medical and laboratory supplies
when purchased.
 
     PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. Depreciation and amortization
are provided for in amounts sufficient to relate the cost of depreciable assets
to operations over their estimated service lives, ranging from three to ten
years. Leasehold improvements are amortized over the lives of the respective
leases or the service lives of the improvements, whichever is shorter. Leased
property under capital leases is amortized over the lives of the respective
leases or over the service lives of the assets, whichever is shorter. The
straight-line method of depreciation is followed for substantially all assets
for financial reporting purposes and accelerated methods are used for tax
purposes.
 
     DEFERRED CHARGES AND INTANGIBLE ASSETS
 
     Deferred charges include deferred loan acquisition costs and organization
costs. These costs are being amortized to operations using the straight-line
basis over the term of the Series B Preferred shareholder's loan guarantee (25
months) and five years for organization costs.
 
     As a result of the Company's acquisitions of certain practice assets and
affiliations with CMG's, the Company acquires and reports intangible assets.
These assets consist principally of long-term management agreements between the
Company and the CMGs. The Company evaluates on a on going basis the period of
amortization of the intangible and determine if the value of the underlying
assets has been impaired. Since events and circumstances surrounding the
acquisition will change over time there can be no assurance that the value of
the intangibles will be realized by the Company. At June 30, 1996 the net
unamortized balance of intangibles acquired was not considered to be impaired.
The Company's policy is to amortize the intangibles over a 10 to 40 year period.
The contracts acquired by the Company in 1995 and 1996 are being amortized over
20 years.
 
     INCOME TAXES
 
     The Company is a corporation subject to federal and state income taxes. The
Company's year-end for tax reporting purposes is December 31. Deferred income
taxes result from the future tax consequences associated with temporary
differences between the amount of assets and liabilities recorded for financial
accounting and income tax purposes. Currently, these temporary differences
relate primarily to net operating loss carryforwards and depreciation
differences. Future use of the net operating loss carryforwards by the Company
may be limited due to certain changes in control as provided for in the Internal
Revenue Code.
 
     Certain of the Company's consolidated subsidiaries are limited liability
companies (LLCs), which are treated as partnerships for federal and state income
tax purposes. The Company's compensation plans for physicians result in these
entities reporting little or no taxable income. To the extent that additional
amounts are paid to member physicians to cover income tax expense incurred, they
will be reported as distributions. These amounts are not deductible for federal
or state income tax purposes.

NOTE 1--BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--CONTINUED
     USE OF ESTIMATES
 
     In preparing financial statements in accordance with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amount of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates.
 
     NEWLY ISSUED ACCOUNTING STANDARDS
 
     In March 1995, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR
LONG-LIVED ASSETS TO BE DISPOSED OF, which requires that long-lived assets and
certain identifiable intangibles held and used by the Company be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. If this review indicates
that the carrying amount of the long-lived assets may not be recoverable, the
carrying value of those assets would be reduced to fair value. The Company has
implemented the standard. Implementation of the standard did not have a material
impact on the Company's financial statements.
 
     In October 1995, FASB issued SFAS No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION, which requires entities to measure compensation costs related to
awards of stock-based compensation using either the fair value method or the
intrinsic value method. Under the fair value method, compensation expense is
measured at the grant date based on the fair value of the award. Under the
intrinsic value method, compensation expense is equal to the excess, if any, of
the quoted market price of the stock at the grant date over the amount the
employee must pay to acquire the stock. Entities electing to measure
compensation costs using the intrinsic value method must make pro forma
disclosures for fiscal years beginning after December 15, 1995, of net income
and earnings per share as if the fair value method had been applied. The Company
has elected to account for stock-based compensation programs using the intrinsic
value method and, therefore, the standard will only impact financial statement
disclosures.
 
NOTE 2--ACQUISITIONS OF CERTAIN ASSETS OF PHYSICIAN GROUPS
 
     During the period ended June 30, 1995 and the year ended June 30, 1996, the
Company acquired certain operating assets and assumed certain operating
liabilities of physician groups located in Maryland. The purchase price has been
allocated to the assets acquired based on the estimated fair values at the dates
of acquisition and the consideration related to long term management agreements.
The estimated fair value of assets acquired, liabilities assumed and
consideration paid are summarized as follows:

NOTE 2--ACQUISITIONS OF CERTAIN ASSETS OF PHYSICIAN GROUPS--CONTINUED
     On February 24, 1995 the Company issued 2,200,000 shares of Class B Common
Stock to MHLP (Medical Holdings Limited Partnership--a Maryland limited
partnership formed to hold the stock). These shares were in consideration of
current and future affiliation of physicians to the CMGs and an expansion of the
physician base encompassed by the PSO Agreements. The affiliation of physicians
and the purchase of their accounts receivable and fixed assets occur when the
practice assets are sold to MHLP in exchange for a limited partnership interest
and the assets are then conveyed to the Company. Simultaneously, the physicians
enter into an employment agreement with one of the affiliated CMGs. Management
believes that the underlying fair value of the PSO Agreement acquired is equal
to the value of the underlying stock held by MHLP at the time of the
acquisition. The percentage of limited partnership interests in MHLP that are
issued are adjusted to reflect the estimated fair value of the Company's stock
at the time the transaction occurs.
 
     Generally the contracts with individual physicians provide for a nine month
period during which the parties may cancel the contract. If this option is
exercised, the Company and the physician would be restored to their respective
positions before the acquisition. Expenses and fees incurred for professional
services in connection with acquisitions are considered part of the acquisition
cost and are capitalized in the financial statements as intangibles. During 1995
and 1996, the Company has capitalized costs of approximately $22,000 and
$43,000, respectively, as part of the acquisitions. In the event that a
physician exercises his option to leave or retire, the Company charges any
unamortized intangibles associated with the acquisition to operations in the
period when notice of withdrawal is received. At June 30, 1996, 25 physicians
had remaining reacquisition options for periods expiring through February 1997.
Total assets at June 30, 1996 and net physician revenues for the year ended June
30, 1996 attributable to physicians with reacquisition rights amounted to
$1,349,499 and $2,574,826, respectively. As of October 3, 1996, reacquisition
rights for 8 of the 25 physicians, or $277,533 in total assets and $1,062,921 in
net physician revenues, have expired without rescission. During 1995, one
physician canceled his interest in the Company. This cancellation did not
require the disbursement of cash or other assets since the transaction was never
funded.
 
NOTE 3--NET REVENUE
 
     The Company's net revenues represent the contractual management and similar
fees earned under its long-term PSO Agreements with CMGs. Under the PSO
Agreements, the Company is contractually responsible and at risk for the
operating costs of the Core Medical Groups with the exception of amounts
retained by physicians. The Company's net revenues include the reimbursement of
all medical practice operating costs and the contractual management fees as
defined and stipulated in the PSO Agreements. Contractual fees are accrued when
collection is probable.
 
     Revenue for all CMGs is recorded at established rates reduced by allowances
for doubtful accounts and contractual adjustments and amounts retained by
physician groups. Contractual adjustments arise due to the terms of certain
reimbursement and managed care contracts. Such adjustments represent the
difference between charges at established rates and estimated recoverable
amounts and are recognized in the period the services are rendered. Any
differences between estimated contractual adjustments and actual final
settlements under reimbursement contracts are reported as contractual
adjustments in the year final settlements are made.

</TABLE>
 
     The Company derives substantially all of its net revenue from three
affiliated core medical groups with which it has PSO agreements. For the year
ended June 30, 1996, one of these core medical groups comprised approximately
93% of the Company's net revenue.
 
     The Company's affiliated core medical groups derived approximately 42% and
21%, respectively, of their net revenues from services provided under
government-sponsored health programs (principally the Medicare and Medicaid
programs) and various Blue Shield contracts, respectively, for the year ended
June 30, 1996. Other than the payors noted, the physician groups have no
customers which represent more than 10% of aggregate net physician revenue for
the year ended June 30, 1996.
 
NOTE 4--OPERATING MATTERS AND LIQUIDITY
 
     It is reasonably possible that future near term events may result in
changes in estimates that would be material to the financial statements.
 
     OPERATING LOSSES; LIQUIDITY
 
     The foregoing business description discusses the current nature of the
Company's operations. Until there are an adequate number of capitated patients
in the Company's global capitated contracts, the Company expects to incur
operating losses and experience negative operating cash flows. The Company
believes that its cash on hand at June 30, 1996, the $7,500,000 received on
September 4, 1996 and the $2,500,000 to be received on or before December 27,
1996 from the holder of its Series C Preferred Stock, the amount of remaining
availability under the NationsBank Credit Facility described in Note 7 and some
portion of the additional capital outlined in Note 18 or other capital, will be
sufficient to meet the Company's working capital needs through June 30, 1997.
However, in the event that the Company either has not attracted an adequate
number of capitated patients in global capitated contracts in order to offset
operating expenses, or has not secured some substantial portion of the
additional capital outlined in Note 18 or other capital, the Company's
operations and liquidity would be adversely affected.
 
     INVESTMENT IN TANGIBLE ASSETS AND INFRASTRUCTURE
 
     For the year ended June 30, 1996, the majority of the Company's revenue
resulted from net revenue generated under the PSO Agreements. In order to
achieve its business objectives and to recover amounts that have been invested
in tangible assets, the formation of the infrastructure and development of the
business, it is necessary for management to renew its current global capitated
contracts and increase the number of enrolled lives. In the event these
contracts are not renewed and expanded to other geographical areas in the
Baltimore and Washington metropolitan area and surrounding regions or the
Company does not increase the number of enrolled lives, the Company would most
likely be unable to generate sufficient revenues to cover its ordinary and
necessary expenses or would not require all of the assets owned or leased.

NOTE 5--NOTE RECEIVABLE
 
     The Company has a note receivable that results from an advance to a medical
practice from which the Company has a binding letter of intent to acquire
certain assets for the approximate value of a portion of the practice's net
realizable accounts receivable. The note was issued to secure the Company's
right to repayment of the face amount of the note in the event that the Company
does not complete the acquisition of certain assets of the medical practice.
Interest on the note is calculated based on the prime rate (8.25% as of June 30,
1996). The note matures on March 1, 1997. Upon consummation of the purchase of
certain assets of the physician's practice by the Company the note receivable
will be cancelled and the advance will be treated as part of the consideration
paid, accordingly, this note has been reflected as a non-current asset.

     In December 1995, the Company entered into a loan agreement with
NationsBank, N.A. (the NationsBank Credit Facility), under which the Company may
request advances up to a maximum of $4 million. Interest on advances is payable
monthly and is calculated based on the bank's prime rate, unless the Company
designates a portion of the advances to be subject to the Eurodollar rate plus
 .75% (effective rate of 6.2% at June 30, 1996). All advances are due at December
31, 1997. The Company has outstanding advances under this agreement of
$3,400,000 at June 30, 1996. The bank has the right to offset the Company's
demand deposit accounts with the bank against any past due amounts.
 
     The NationsBank Credit Facility is guaranteed by the holder of the
Company's Series B Preferred Stock. The guarantee is collateralized by a
security interest in all receivables and the PSO Agreements between the Company
and Baltimore Medical. The guarantee agreement also provides for certain
restrictions on the Company, including limitations on incurring additional debt
and reduction of amounts due from the Series A Preferred Stockholder. Upon
redemption of the Series B Preferred Stock in connection with issuance of
"junior stock" to a holder whose interests are deemed adverse to the guarantor,
then the Company is required to obtain a release of the guarantee. As
consideration for the guarantee, the Company issued a warrant valued at $370,000
for the purchase of its common stock (see note 13).

NOTE 7--NOTES PAYABLE AND LONG-TERM OBLIGATIONS--CONTINUED
     In connection with the acquisitions of certain assets of medical practices
and other transactions, the Company is obligated on short-term notes payable to
physicians and others aggregating approximately $303,915 at June 30, 1996.
 
     The Company is also obligated on notes payable to various physicians, who
are members of either Baltimore Medical, Carroll Medical or Cumberland Valley
Medical, in connection with the original purchase of the accounts receivable
from the physicians' former practices. The notes bear interest at rates ranging
from 9.75% to 10% and the notes mature at the earlier of seven years from the
date of closing or any of the following events: (i) termination of the
respective Professional Services Employment Agreements, (ii) a liquidating
distribution to the stockholders of the Company, (iii) combination,
consolidation or merger where the Company is not the survivor, (iv) disposal of
substantially all of the Company' assets, or (v) a public offering with a
certain cash issuance amount to the Company. The notes may be reduced or
adjusted based on receivable collections and may be prepaid without penalty. The
Company does not expect to conclude an underwritten public offering of the
Company's securities for cash before June 30, 1997. Accordingly, these notes
have been classified as long-term obligations.
 
NOTE 8--CAPITAL LEASE OBLIGATIONS

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

Company). Management believes that losses and costs related to unknown incidents
not provided for, if any, would not be material to the financial position,
liquidity or results of operations of the Company.
 
     Pursuant to an agreement dated December 1, 1995, the prior written approval
of the Series B Preferred Stockholder is required in connection with decisions
regarding medical malpractice coverage for the Company, participating physicians
and affiliated entities. Such decisions include, but are not limited to, the
selection of the underwriter, the form of the insurance policy and the premium
payment provisions. The Company must make certain payments to the Series B
Preferred Stockholder if the required approval is not obtained: the Series B
Preferred Stockholder could require the Company to pay it $400,000 and to redeem
all or a portion of the Series B Preferred Stock at the price equal to the
greater of the fair market value per share or the sum of the issue price per
share and all accumulated and unpaid interest and dividends. The Series B
Preferred Stockholder agrees to provide medical malpractice coverage to the
Company for premiums consistent with its rates as approved by the Maryland
Insurance Administration. In addition, the Series B Preferred Stockholder will
consider alternative insurance programs to meet the Company's special needs and
will request the necessary approvals for such alternative programs from the
Maryland Insurance Administration. This agreement terminates upon the earlier of
a change in control of the Company or termination of the loan guarantee provided
by the Series B Preferred Stockholder.
 
     EMPLOYEE BENEFIT PLANS
 
     Effective January 1, 1996, the Company adopted a 401(k) Plan (the Plan)
covering all its employees. Subject to certain limitations, participants may
elect to defer a portion of their compensation as contributions to the Plan. The
Company will make matching contributions of 50% of each participant's
contribution up to six percent of the participant's salary. Participants vest in
the Company's contributions at the rate of 20% per year beginning in fiscal
1997. Contributions of $160,000 were expensed in fiscal 1996.
 
     Effective February 1, 1996, the Company adopted a Flexible Benefits Plan
covering all full-time employees. Subject to certain limitations, the Company
may make "non-elective contributions" on behalf of employees and employees may
elect to defer a portion of their compensation as "flexible pay contributions"
to pay for certain covered expenses.
 
     OPERATING LEASES
 
     The Company conducts its operations at leased facilities and uses leased
office equipment under noncancelable operating leases. Certain of the leased
facilities are owned by physicians who have membership interests in affiliates.
Amounts paid to the related parties approximated $8,700 and $14,500 in 1995 and
1996, respectively. 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
$74,228 and 454,000 for 1995 and 1996, respectively. Effective October 1, 1996,
the Company entered into a 35 month operating lease for additional corporate
office space. Lease payments for the additional office space approximate
$189,000 per year. Minimum rental commitments, excluding sublease income, under
operating leases as of June 30, 1996, with existing or renewable terms greater
than one year are as follows (the Company has $34,800 of minimum rental
commitments due in 1997 to related parties):

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

scheduled for 1996. Upon redemption or conversion of Series A Preferred Stock,
any unpaid principal on the note is to be canceled in an amount equal to five
dollars times the number of shares converted or redeemed. The Company has the
option to require payment of any outstanding principal and interest on February
14, 1998, or the Company may elect to redeem the outstanding Series A Preferred
Stock and cancel the remaining principal and interest.
 
     PREFERRED STOCK DIVIDENDS
 
     Series A Redeemable Convertible Preferred Stock accrues dividends quarterly
at the rate of thirty-two and one half cents ($0.325) per share per annum
beginning on February 24, 1995. Unpaid dividends accrue interest at the rate of
6.5% per annum, compounded quarterly, and may be offset by the Company against
any unpaid interest that is owed by the holders of the Series A Redeemable
Convertible Preferred Stock under the related note receivable.
 
     Series B Redeemable Convertible Preferred Stock accrues dividends quarterly
at the rate of one dollar and nine and seven tenths cents ($1.097) per share per
annum beginning December 1, 1995. Unpaid dividends accrue interest at the rate
of 9.75% per annum, compounded quarterly.
 
     Until April 1, 2000, payment of dividends on Series A Preferred Stock and
Series B Preferred Stock are only permitted in the event of redemption,
conversion or liquidation, and, in any event, dividends on Series B Preferred
Stock may only be paid after all dividends and interest on the Series A
Redeemable Convertible Preferred Stock have been satisfied. Beginning April 1,
2000, dividends on Series A Preferred Stock and Series B Preferred Stock will
accrue at a rate equal to the prime rate plus 100 basis points.
 
     Cumulative Series A and Series B Redeemable Convertible Preferred Stock
accrued and undeclared dividends at June 30 are as follows:

     The Company's cumulative Series A and Series B Preferred Stock are subject
to redemption; accordingly, for financial reporting purposes accrued dividends
are reflected as an accretion in the value of the preferred stock with a
corresponding reduction in stockholders' equity to reflect redemption value.
 
     PREFERRED STOCK LIQUIDATION PREFERENCES
 
     Upon liquidation or dissolution of the Company, the Series A and Series B
Preferred Stockholders are entitled to receive a liquidating distribution in an
amount equal to the greater of: (i) the fair value (as defined) per share of the
respective series of preferred stock or (ii) the original purchase price per
share of the respective stock. The distribution will also include all unpaid
cumulative dividends and accrued interest thereon; however, the total
distributable amount due to each preferred stockholder is limited to the amount
of cash paid to the Company for the purchase of the respective shares. No
distribution will be paid to the Series B Preferred Stockholder until all
amounts due to the Series A Preferred Stockholder have been fully paid.
 
NOTE 11--STOCKHOLDERS' EQUITY
 
     All of the Company stockholders are parties to an agreement dated December
1, 1995 (see Note 18 for September 4, 1996 amendment), that restricts transfer
of the Company stock. The agreement terminates upon occurrence of certain
specified events, including a public offering of the Company stock. Under the
terms of the Stockholders' Agreement, the Company may be required to purchase
shares of the Company's capital stock in certain circumstances, such as: (i)
Class A Common Stock owned by management stockholders, in the event of their
death (for which the Company has purchased insurance based on the Company's
current valuation for common stock of $7.00 per share) or disability (See Note
20) if other management stockholders do not exercise their rights to acquire the
shares offered, in which case the Company is required to

NOTE 11--STOCKHOLDERS' EQUITY--CONTINUED
purchase all of the offered shares at fair value (as agreed to by the parties or
as determined by an independent appraisal); (ii) Class A Common Stock purchased
by Dr. Rifkin or Dr. Kimmel after December 1, 1995, if their employment is
terminated, in which case the Company is required to purchase these shares at
fair value (as agreed to by the parties or as determined by an independent
appraisal); (iii) Class A Common Stock owned by other management stockholders if
their employment is terminated and the remaining management stockholders do not
exercise their rights to acquire the shares offered, then the Company is
required to purchase all of the shares offered. If termination is without cause,
the purchase price is based on fair value (as agreed to by the parties or as
determined by an independent appraisal). If termination is with cause, then the
purchase price is the lesser of $1 per share or the original issuance cost of
the shares. At June 30, 1996, 800,000 shares of Class A Common Stock were
subject to such repurchase requirement. Based on the current fair value of the
Company's stock, the repurchase obligation for 800,000 shares in the event of a
disability to all three Class A Common Stockholders would be $5,600,000. If the
Company is required to purchase shares of the management stockholder under the
foregoing circumstances, then all accrued dividends due to Series A and Series B
Preferred Stockholders must first be paid; (iv) All classes of capital
stock--upon the occurrence of an involuntary transfer involving any of its
outstanding capital stock, the Company has the right of first refusal to
purchase the offered shares at fair value (as agreed to by the parties or as
determined by an independent appraisal).
 
     All classes of Common Stock have the same preferences, rights and voting
powers. A portion of the Class A Common Stock is reserved for issuance upon
exercise of warrants, and a portion of the Class C Common Stock is reserved for
issuance to the holders of Series A Preferred Stock and Series B Preferred Stock
upon conversion of those shares of stock.
 
NOTE 12--STOCK OPTIONS
 
     The Company has an Omnibus Stock Plan (the Plan) which is accounted for
under APB Opinion 25 and related Interpretations with respect to employee
transactions. Transactions with non-employees are accounted for at fair value at
the date of grant and are immaterial as of June 30, 1996. The Plan permits the
Company to grant incentive and non-qualified stock options, stock appreciation
rights (SARs) and restricted or unrestricted share awards to directors,
officers, employees and other key contributors to the Company. SARs entitle the
optionee to surrender unexercised stock options for cash or stock equal to the
excess of the fair value of the surrendered shares over the option value of such
shares. The Plan is administered by a committee (the Committee) appointed by the
Company's Board of Directors. Subject to adjustment as provided in the Plan, the
aggregate number of shares of the Company Common Stock which may be awarded is
limited to 6,175,000. Shares under any grants that expire unexercised are
available for further grant.
 
     The exercise price and exercise period for stock options is determined by
the Committee, provided that the exercise period may not exceed 10 years from
the grant date and the exercise price for incentive stock options may not be
less than 100% of the fair value of the shares on the date the option is
granted. Incentive stock options are granted only to employees of the Company.
 
     In August and October 1995, the Company granted incentive stock options, to
purchase Class A Common Stock, to ten employees for a total of 118,380 shares at
the exercise price of $0.01 per share, the estimated fair value of the shares at
the date of grant based on the financial position and liquidity of the Company
and the limited marketability of the shares. The options become exercisable on
various dates ranging from April 1, 1996 through April 1, 2000. Upon exercise,
68,832 shares will be fully vested and nonforfeitable; the remainder vest
ratably over four years. Options may expire or become exercisable, and shares
issued may be fully vested, at earlier dates upon occurrence of certain
specified events, including a change in control of the Company or the employee's
death, disability, retirement, or termination without cause. During 1996,
employees forfeited 20,050 Class A Common Stock options.
 
     In December 1995, the Company granted non-qualified stock options to
purchase Class A Common Stock to three employees for a total of 12,500 shares at
the exercise price of $0.01 per share. The options become exercisable on
December 21, 1996. Upon exercise, 5,000 shares issued will be fully vested and
nonforfeitable; the remainder vest ratably over four years. Options may expire
or become exercisable, and shares issued may be fully vested, at earlier dates
upon occurrence of certain specified events, including a change in control of
the Company or the employee's death, disability, retirement, or termination
without cause. The Company will recognize compensation expense as the shares
vest in future periods, based

NOTE 12--STOCK OPTIONS--CONTINUED
upon the option price and fair value at the date of grant. The fair value of the
common stock at the time of grant in December 1995, $3.00 per share, was based
on a discounted value of the per share price of the Company's Series B
Redeemable Convertible Preferred Stock.
 
     In May 1996, the Company granted incentive stock options to purchase Class
A Common Stock for 70,000 shares with an exercise price of $11.00 per share to
an employee, which was deemed to be in excess of management's estimate of fair
value at the date of grant.
 
   
     As of June 30, 1996, the Company has also granted options to purchase
105,000 shares of Common Stock. In February 1995, the Company granted an
incentive stock option to purchase 100,000 shares of Class A Common Stock to an
officer of the Company at an exercise price of $0.01 per share, and in October
1995, the Company granted a non-qualified stock option to purchase 5,000 shares
of Class B Common Stock to a physician at an exercise price of $0.01 per share.
The estimated fair value of the stock was determined to be equal to the exercise
prices on the July 1994 and October 1995 grant dates.
    
 
NOTE 13--COMMON STOCK PURCHASE WARRANTS
 
     In consideration for the guarantee of a loan agreement, the Company issued
on December 1, 1995 a warrant to its Series B Preferred Stockholder for the
purchase of 88,889 shares of the Company Class A Common Stock at $5.625 per
share. The warrant expires on December 1, 2005 and is exercisable (i) if the
holder does not receive notice of a change in control within thirty days after
the change is effective or (ii) ninety days prior to the filing of a
registration statement for a public offering that includes shares held by
management stockholders. The warrant was valued at the present value of the
difference between the estimated fair value of the common stock subject to the
warrant and the aggregate strike price, discounted at the interest savings rate
(the difference between the rate obtained on the loan agreement and the rate of
interest that management believes would have been available without the
guarantee). At June 30, 1996, this amount ($370,000) is reflected as additional
paid-in capital and a deferred charge, which is being amortized on the interest
method over 25 months (the length of the guarantee).
 
     On December 1, 1995, in consideration for certain consulting services, the
Company issued warrants for the purchase of 24,000 shares of the Company common
stock at $11.25 per share (a price greater than management's estimate of fair
value at the date of grant). A value was not attributed to these warrants at the
time of issue. These warrants expire December 1, 2005, and are exercisable if
there is a change in control of the Company.
 
NOTE 14--FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts of financial instruments included in current assets
and current liabilities approximate fair values because of the short maturity of
those instruments. The following methods and assumptions were used to estimate
the fair value of each class of financial instruments for which it is
practicable to estimate that value:
 
     REDEEMABLE CONVERTIBLE PREFERRED STOCK AND SERIES A PREFERRED STOCK
SUBSCRIPTION RECEIVABLE
 
     The Series A and Series B Preferred Stock are carried at issue price plus
accrued dividends, and have features unique to these securities including, but
not limited to, the right to appoint directors and the right to approve certain
significant activities of the Company. There is no quoted market price for the
Series A or Series B Preferred Stock, however, management believes that the
initial recorded amounts approximate fair value.
 
     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.

NOTE 14--FAIR VALUE OF FINANCIAL INSTRUMENTS--CONTINUED
     LONG-TERM OBLIGATIONS
 
     Long-term obligations, excluding capital lease obligations, were incurred
by the Company when individual physicians joined the affiliated CMGs. 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 15--INCOME TAXES
 
     The Company has accumulated net losses from operations of $8,414,261.
Significant temporary differences between the determination of this loss for
financial reporting and income tax purposes include depreciation, the allowance
for uncollectible receivables, and certain accrued liabilities. These losses may
be carried forward for 15 years and expire at various dates through 2010. Under
federal tax law, certain changes in ownership of the Company, which may not be
within the Company's control, may operate to restrict future utilization of
these carryforwards. As of June 30, 1996, based on the available information, it
is more likely than not that the deferred tax assets will not be realized and as
a result have been fully reserved at June 30, 1995 and 1996. Deferred tax assets
(liabilities) at June 30, 1995 and 1996, consist of the following:

     On August 15, 1996, the Company established a $1,500,000 bridge loan
facility (the "Bridge Loan") with First National Bank of Maryland, N.A. ("First
National"). The Bridge Loan is collateralized by certain assets of the Company
and its affiliates and is guaranteed by the Series A Preferred Stockholder.
Advances under this facility bear interest at a rate of 6.71% per annum. The
Bridge Loan matures on January 15, 1997 and management is currently negotiating
with First National to replace the Bridge Loan with a $10,000,000 credit
facility (the "First National Credit Facility"). As of September 30, 1996,
approximately $983,000 had been advanced under the Bridge Loan to fund corporate
expenses in conjunction with the Company's strategy. Although there can be no
assurances the Company will obtain the First National Credit Facility, the
Company is proceeding with the loan approval process with First National and the
Company believes, based on conversations with First National and the Series A
Preferred Stockholder, if the loan approval process is not completed before the
maturity date of the Bridge Loan, that the maturity date will be extended until
such time that the loan approval process is completed. In the event the Company
is unable or unwilling to secure the First National Credit Facility or the
maturity date of the Bridge Loan is not extended, the Bridge Loan is expected to
be repaid on or before January 15, 1997 from the Company's available cash.
 
     ACQUISITIONS
 
     The Company intends to continue its ongoing acquisition of certain assets
of primary care and specialty practices. The Company is currently engaged in
negotiations with several providers of health care services. Certain of these
acquisitions provide for the purchase of the assets under terms and conditions
similar to those that the Company has entered into previously. When the Company
closes one of the acquisitions that it is currently negotiating, it will
guarantee indebtedness of approximately $850,000 and assume $325,000 in
outstanding debt.
 
     The Company will issue approximately 513,000 shares of the Company's Class
B Common Stock having an estimated fair value of $3,591,000 as part of the
consideration paid on all of the providers of health care services it is in
negotiation

with. Of this total approximately 195,000 shares having an estimated fair value
of $1,365,000 represent 10 limited partnership interests in MHLP and the
remaining 318,000 shares to be issued by the Company have an estimated fair
value of $2,226,000. Certain of the individual physicians involved in these
acquisitions will be granted options to purchase additional shares of the
Company's Class B Common Stock in the event certain agreed upon performance
criteria are met. These agreements which have not yet closed provide for a total
of 53,000 option shares. In addition, 14,000 shares of Class B Common Stock have
been reserved for future issuance to physician employees of one of the practices
purchased subsequent to June 30, 1996.
 
     In the event that all of the acquisitions are consummated under the terms
currently agreed upon the Company will acquire assets of approximately
$5,260,000.
 
NOTE 19--RELATED PARTIES
 
     Amounts due under the terms of the PSO agreements between the Company and
the affiliated medical groups are reflected in the Due to/from Affiliates on the
consolidated balance sheet. The amounts due from the affiliates represents
working capital advances, amounts due for management fees from BMG LLC related
to the management of the laboratory and management fees due under the PSO
agreement. The amounts due to the affiliates represents amounts due to the
physicians related to the collection of accounts receivable.
 
     Because of the nature of the Company's arrangements with Affiliated CMGs,
substantially all transactions included in Net Revenues, Medical Services
Expense and Care Center Costs in the accompanying financial statements are
viewed as related party transactions.
 
     MHLP was formed on February 24, 1995 to hold the Class B Common Stock that
was issued by the Company and intended to be used for the acquisition of PSO
agreements by the Company. MHLP has no assets other than the Class B Common
Stock of the Company and has no liabilities or operations.
 
     Three of the Company's executive management members and four directors are
practicing physicians with CMGs affiliated with the Company.
 
     During the year ended June 30, 1996, the Company paid approximately $98,000
to the Series B Redeemable Convertible Preferred Stockholder for professional
liability insurance on behalf of the affiliated CMGs in connection with the PSO
agreement.
 
     The Company has entered into acquisition transactions with certain of its
directors who are physicians. These transactions were entered into on
commercially reasonable terms, substantially similar to the terms of its
acquisition transactions with other affiliated physicians, and the consideration
paid in connection with such acquisitions was based on the fair market value of
the medical practice assets or services acquired:
 
     (a) During the year ended June 30, 1996, the Company purchased certain
assets of a director of the Company, and four physician partners of the
physician. The physician and his four partners received a limited partnership
interest in MHLP equivalent to 167,000 shares of Class B Common Stock, valued at
$3.00 per share, and a promissory note with a face value of approximately
$158,000 as consideration for the acquisition.
 
     (b) During the year ended June 30, 1996, the Company purchased certain
assets of a director of the Company. In addition, the physician received a
limited partnership interest in MHLP equivalent to 33,000 shares of Class B
Common Stock, valued at $3.00 per share, approximately $34,000 in cash and a
promissory note with a face value of approximately $45,000 as consideration for
the acquisition.
 
     (c) Subsequent to June 30, 1996, the Company purchased certain assets of a
director of the Company. The physician received 16,000 shares of Class B Common
Stock and 1,000 options to acquire Class B Common Stock, valued at $7.00 per
share, cash in the amount of $5,000 and a promissory note with a face value of
approximately $38,000 as consideration for the acquisition.

NOTE 19--RELATED PARTIES--CONTINUED
     (d) Subsequent to June 30, 1996, the Company entered into a letter of
intent with a director of the Company to purchase certain assets of his medical
practice. In connection with the acquisition, the physician's limited liability
partnership, which he owns with five other physicians, will receive a limited
partnership interest in MHLP equivalent to 74,000 shares of Class B Common
Stock, an option to acquire a limited partnership interest equivalent to 20,000
shares of Class B Common Stock, exercisable at $15.00 per share, and cash for
the practice's collectable accounts receivable, which will not exceed $625,000.
The Company has advanced $300,000 to the physician and the practice for the
purchase of the practice's accounts receivable and received a promissory note
from the physician evidencing such advance. The promissory note will be canceled
at the closing of the acquisition. The Company has delegated to the physician's
practice, and the practice will perform, certain practice management business
functions, which the Company ordinarily performs for its physicians at its
headquarters. The Company reimburses the physician's practice $50,000/month for
the expenses it incurs in performing the business management services. The
amount reimbursed for the year ended June 30, 1996 was $100,000.
 
NOTE 20--COMMON STOCK REPURCHASE AGREEMENT
 
   
     As outlined in Note 11, under the terms of the Stockholders' Agreement, the
Company may be required to purchase shares of the Company's capital stock in
certain circumstances including death or disability. As of June 30, 1996, the
Company had obtained insurance to cover the purchase of the capital stock in the
event of death. On December 20, 1996, the Company obtained insurance to cover
the purchase of the capital stock in the event of a disability. Under each of
the above policies, the Company has obtained insurance that is in excess of the
estimated fair value of its Class A Common Stock. In order to comply with
Article 5 of Regulation S-X, the Company has presented the common stock that is
redeemable based on events outside the Company's control (i.e. a disability) as
Redeemable Class A Common Stock in the accompanying Balance Sheets as of June
30, 1995 and 1996. As a result of the coverage provided by the life and
disability policies described above, there are no circumstances in which a
redemption event would result in a decrease in the Company's stockholders'
equity. The Company will present the Class A Common Stock as stockholders'
equity in all balance sheets subsequent to December 20, 1996. The Company has
presented an unaudited Pro Forma Balance Sheet as of September 30, 1996 assuming
the Class A Common Stock is covered by insurance for any event of redemption.
While the Company believes the insurance policies are currently sufficient,
redemption is based upon fair value. Any increase in fair value above the
insured amount in conjunction with the occurrence of a death or disability event
for one or all of the covered employees would result in a reduction in the
stockholders' equity of the Company. The Company intends to maintain insurance
at levels sufficient to finance its redemption obligations. As of January 13,
1997, the Company is not aware of any previous or current disability events
which would result in the redemption of the Class A Common Stock. The terms of
the stock repurchase agreement terminate in the event of an initial public
offering or a change in control of the Company as defined in the Stockholders'
Agreement.

                DOCTORS HEALTH SYSTEM, INC. AND ACQUIRED ASSETS
 
     The following pro forma consolidated balance sheet as of September 30,
1996, gives effect to (1) the acquisition of certain assets of physician
practices during the three months ended September 30, 1996, (2) probable
issuance of Senior Subordinated Notes Payable, (3) the acquisition of certain
assets of physician practices subsequent to September 30, 1996 and (4) the
proposed acquisition of certain assets of physician practices subsequent to
September 30, 1996, which are probable (collectively the "Acquired Assets") by
Doctors Health System, Inc. (DHS). Subsequent to the purchase of certain assets
of the physician practices, the Company entered into long-term PSO agreements
with the Core Medical Group which employs the physicians. These transactions are
reflected as of September 30, 1996 for the pro forma consolidated balance sheet.
The pro forma information is based on the respective historical unaudited
balance sheets of Doctors Health System, Inc. and the Acquired Assets, giving
effect to the completed and proposed acquisitions at cost and the assumptions
and adjustments described in the accompanying notes to the pro forma
consolidated balance sheet.
 
     Management of DHS does not believe that the pro forma consolidated balance
sheet is indicative of the results that actually would have occurred if the
combinations had been in effect on the dates indicated or which may be obtained
in the future. The pro forma consolidated balance sheet should be read in
conjunction with the financial statements and notes of DHS contained elsewhere
herein.

            NOTES TO UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET

A.  Represents the pro forma historical unaudited consolidated balance sheet of
    the Company at September 30, 1996.
 
B.  To reflect the issuance of Series C Redeemable Convertible Preferred Stock.
    This amount represents the $2.5 million received on January 2, 1997.
 
   
C.  To reflect the expected issuance of $35 million in senior subordinated debt.
    A portion of the proceeds from the issuance will be used to retire the
    NationsBank Credit facility ($3,600,000), to retire the Bridge loan
    ($983,000), and to fund issuance costs ($1,600,000). Although the terms of
    the Notes have not been determined, the Notes are expected to (i) carry an
    interest rate from 11% to 15%, (ii) mature in seven years and (iii) include
    redemption provisions permitting the Company to redeem the Notes under
    certain circumstances. The Notes would include covenants that limit the
    Company's ability to incur indebtedness senior to the Notes, but would
    permit the issuance of up to $15 million in senior secured debt for working
    capital purposes. In addition, as part of the issuance of the Notes, the
    Company anticipates that it will issue warrants to purchase between 350,000
    and 900,000 shares of Class A Common Stock at an exercise price of between
    $15.00 and $20.00.
    
 
D.  Represents the acquisitions completed subsequent to September 30, 1996. See
    "Management's Discussion and Analysis of Financial Condition and Results of
    Operations--Acquisitions/Affiliations."

F.  The estimated fair value of the Common stock issued in the acquisitions was
    $7.00 and was determined by management of the Company based upon factors
    including sales of redeemable convertible preferred stock to unaffiliated
    third parties, the financial condition of the Company, the significant
    preferences provided to the redeemable convertible preferred stockholders
    relative to the Common Stock, and the operating losses being generated by
    the Company.
 
G.  None of the transactions to acquire certain assets of physician practices
    subsequent to June 30, 1996 required the Company to assume any liabilities
    of the practices.

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

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes:
 
     (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 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
 
                                      II-5
 
<PAGE>
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.

Owings Mills, MD 21117

Ladies and Gentlemen:

     Doctors  Health  System,  Inc., a Maryland corporation (the "Company"), has
filed a Registration Statement on Form S-1 (the "Registration  Statement")  with
the Securities and Exchange Commission (the "Commission")  under  the Securities
Act of 1933, as amended (the "Act"), with respect to the issuance of  up  to (i)
4,100,000 shares of Class B Common Stock, par value  $0.01  per  share,  of  the
Company ("Class B Common Stock"), and up  to  (ii) 1,000,000 options to purchase
Doctors  Health  System  Class  B  Common  Stock  ("Options") in connection with
acquisitions  of  medical  practices  or  other  transactions  with   physicians
("Affiliations") and in  accordance  with  binding  acquisition  or  affiliation
agreements ("Affiliation Agreements").

     In connection with this opinion, we have examined or relied upon  corporate
documents and records of the Company, certificates of officers  of  the  Company
and such other documents as we have deemed appropriate;  have  made inquiries as
to questions of fact of officers and representatives of the  Company;  and  have
made such examinations of law as  we  have  deemed  relevant for the purposes of
this  opinion.  We  have  assumed,   without   independent   verification,   the
authenticity of all documents submitted to us as originals and the conformity to
authentic  original  documents  of  all  documents submitted to us as certified,
conformed or photostatic copies.

     Based on the foregoing, it is our opinion that:

     1. Upon proper authorization of the issuance of shares of  Class  B  Common
Stock  by  the  Board  of  Directors  of  the  Company  in  connection  with  an
Affiliation, the  Class  B Common Stock will be duly authorized and, when issued
in connection with a duly   authorized  Affiliation  pursuant  to an Affiliation
Agreement or pursuant to the exercise of  duly  authorized  and  issued options,
will be validly and legally issued and will be fully paid and non-assessable.

<PAGE>

     2. Upon proper authorization of the issuance of Options to  acquire  shares
of Class B Common Stock by the Board of Directors of the Company  in  connection
with an Affiliation, the Options will be duly authorized  and,  when  issued  in
connection with  a  daily  authorized  Affiliation  pursuant  to  an Affiliation
Agreement, will be validly issued.

     3. The shares of Class B Common Stock  being  offered  by  the  Company  in
connection  with  the  proposed  merger  with Medtrust Medical Group, Inc., when
issued and sold in accordance with the terms described in the  Merger  Agreement
filed as Exhibit 10.46 to the Registration Statement, will  be  validly  issued,
fully paid and non-assessable.

     We express no opinion as to the laws of any  jurisdiction  other  than  the
corporate laws of the State of Maryland.

     We hereby consent to the filing of  this  opinion  as  an  exhibit  to  the
Registration Statement and to the reference to  our  name  in  the  Registration
Statement under the caption "Legal Matters."  In  giving this consent, we do not
admit that we are in the category of persons whose  consent  is  required  under
Section 7 of the Act, or the Rules and Regulations of the Commission thereunder.

                                              Very truly yours,

Medtrust Medical Group, Inc.
Suite 510
3251 Old Lee Highway
Fairfax, VA 22030-1509

Gentlemen:

     You have requested our opinion that the proposed merger of Medtrust Medical
Group,  Inc.  ("Medtrust")  into  Doctors  Health  of  Virginia, Inc. ("Sub") in
exchange for Class B common stock of Doctors Health  System,  Inc.  ("DHS")  and
other  consideration  will  constitute  a  reorganization  within the meaning of
Section 368 (a) of  the  Internal Revenue Code of 1986 ("the Code"), and various
additional and related issues.

     Due  to  the  complexity  of  the  federal  income  tax law and the lack of
authority concerning many issues addressed herein, there  can  be  no  assurance
that the issues which are opined on herein, if they were to be litigated,  would
be decided favorably to Medtrust or its Members. In addition, our opinion  as to
any issue is not a guarantee of a  favorable outcome  if that  issue were  to be
litigated. Because of the importance  of the  tax issues related to the proposed
merger, an unfavorable decision on any of these  issues  might  have  a  serious
adverse effect on Medtrust and or its Members.

     This  letter  is  not  intended  to encompass all of the federal income tax
consequences which could result  from  the  steps  contemplated  in  the  Merger
Agreement  (as  hereinafter defined).  It is intended to cover only the material
tax issues relating directly  to  the merger.  The opinions expressed herein are
not binding on the Internal Revenue Service (the "Service"), and there can be no
assurance that the Service will not take a  position  contrary  to  any  of  the
opinions expressed herein; or if the Service  took such a position, it would not
be sustained by the courts.

     We  have  made  such  inquiries and have examined such questions of law and
such documents, including those set forth below, as we have considered necessary
for the purposes of this opinion:

     (1) The  Plan  and  Agreement  of  Merger  (the "Merger  Agreement")  among
Medtrust Medical Group, Inc., Doctors Health System, Inc., and Doctors Health of
Virginia, Inc. dated as of November 15, 1996, as amended December 23, 1996;

     (2) The  Amendment  No.  6 to the Proxy Statement/Prospectus Supplement for
Doctors Health System Class B Common Stock as  filed  with  the  Securities  and
Exchange Commission on January 16, 1997; and

     (3) The  Amended  and  Restated  Stockholders  Agreement  of Doctors Health
System, Inc. dated as of September 4, 1996.

     Our opinions, as expressed herein, are based solely on the  information and
representations contained in such documents and  certain  other  representations
and additional information that the parties have given us, the accuracy of which
(specifically including but not limited to any determination of  value  referred
to herein) has not been independently investigated or determined.  For  purposes
of this opinion, the parties have represented to us and on the basis thereof, we
make the following assumptions:

     (1) That  all  representations,  warranties,  covenants,  and duties of the
parties contained in the  foregoing  documents  have  been  and  will  be  fully
performed and complied with  in accordance with their terms including the actual
merger of Medtrust into Sub in full compliance with the applicable provisions of
federal and state law.

     (2) That  no  actions  will  be  taken  or  omitted  by any of the parties,
including the individual shareholders of the incorporated Members  of  Medtrust,
after the  date  hereof  which  would  be  inconsistent  with  any  of the above
documents in  their  present  form,  the  assumptions  set  forth herein, or the
continued eligibility of the merger to be treated as a reorganization  described
in Section 368 (a) of the Code.

     (3) That  DHS  has  no  present  plan  for  the disposition, liquidation or
termination of the business of Sub or its interest in  Sub,  and  following  the
merger, DHS will control and maintain Sub as a separate  operating  corporation,
continuing the principal business activities of Medtrust.

     (4) That no Member of Medtrust or any shareholder of an incorporated Member
of Medtrust has any present agreement, plan or intention to  sell  or  otherwise
dispose of  any  DHS  shares  transferred  pursuant  to  the  Merger  Agreement,
including  but  not  limited  to  the  transfer  by  a  Medtrust  Member  to its
shareholders or employees.

     (5) That each of the parties including DHS, Medtrust  and  each  individual
recipient will treat the additional payment  of  cash  and  DHS  shares  to  the
individuals serving on the Negotiating Team as  a  separate payment for services
directly related to the merger, and not in exchange for their direct or indirect
interest in Medtrust, and that the value of such payment  is reasonable in light
of the value of such services.

     (6) That the rights, if any, granted to Members of Medtrust and  individual
physicians pursuant to Section 7 of the Merger Agreement represent  an agreement
to pay for future services of the organizations and/or  individuals to whom such
rights are granted, that any future  contract,  benefit  or payment based on the
granting of such rights will  be  commercially reasonable and will be equal to a
fair and arms length value based on the service(s) to be provided, and that such
rights will have no value  at  the  time of the merger if viewed separately from
the obligation to perform future services.

     (7) That the fair market value of the DHS Class B shares to  be  issued  to
Members of Medtrust will be not less than $ 7. 00  per  share;  the  Members  of
Medtrust and their respective  shareholders will receive no consideration in the
merger   other  than   that  set  forth  in  the  foregoing  documents;  and  no
distributions of cash or  other property will be made by Medtrust to its Members
prior to the merger.

     (8) That the total of all expenses related to  the  merger  that  are  paid
directly by Medtrust will not exceed $32,000,  and  the  balance  of any cash or
cash equivalents held by Medtrust at the time of merger will become the property
of Sub.

     (9) That the fair market value of  the  DHS  shares  received  by  Medtrust
Members, excluding any shares received by the Negotiating Team,  will  equal  no
less than 40% of the total consideration provided  to  the  Medtrust  Members in
exchange for their respective interests in Medtrust.

                                    OPINION

     Subject to the conditions, assumptions, representations,  facts  and  legal
analysis set forth in this letter, our opinion is that:

     1. The Merger will constitute a tax-free reorganization under  Section  368
(a)  of  the  Code,  and  DHS,  Sub,  and  Medtrust  will each be a party to the
reorganization within the meaning of Section 368 (b) of the Code;

     2. No  gain  or  loss  will  be  recognized  by Medtrust as a result of the
Merger;

     3. No gain or loss will be recognized by a Medtrust Member with respect  to
shares of Class B Common Stock received from DHS in exchange for Medtrust Member
Interests;

     4. The  tax  basis  of  the  shares  of  Class B Common Stock received by a
Medtrust  Member  will  be  equal  to  the  aggregate  tax basis of the Medtrust
Interests exchanged therefor, reduced by an amount  allocable  to  a  fractional
share of Class B Common Stock for which cash or other consideration is received;
and

     5. The holding period of the shares of Class B Common Stock received  by  a
Medtrust  Member  will  include  the  holding  period or periods of the Medtrust
Member Interest exchanged therefor.

     In connection with the foregoing opinion, we note the following:

     A. The foregoing opinion is based on present provisions of the Code and the
Regulations  as  well  as  certain  administrative  and judicial interpretations
thereof. Consequently, future events which would modify or otherwise affect such
provisions,  interpretations,  or their application may result in federal income
tax treatment that is materially and  adversely  different  from  that described
above for taxable years arising both before  and  after  the  occurrence of such
events.

     B. No opinion is expressed as to any matter not expressly discussed herein.

     C. No  opinion  is  expressed  as to the tax consequences arising under the
laws of any state, locality or foreign jurisdiction.

     D. No  opinion  is  expressed  as  to  the  tax  consequences of any of the
transactions contemplated by the Merger Agreement related to individuals who are
not direct Members of Medtrust, including but not  limited  to  shareholders  of
incorporated Members of Medtrust. You should be aware  that  the distribution or
transfer of DHS shares from an incorporated  Member  to  its  shareholders could
have substantial tax consequences both with respect to  issues discussed in this
opinion and with respect to issues beyond the scope of this opinion. Finally, we
do  not  undertake to advise you of any changes of any opinions expressed herein
resulting  from  matters  that  might  hereafter  come  to  or be brought to our
attention.

     We consent to the filing of this opinion as an exhibit to the  Registration
Statement and to the use of our name in the Registration  Statement.  In  giving
such consent, we do not thereby admit that we are acting within the category  of
persons whose consent is required under Section 7 of the Act and  the  rules and
regulations of the Securities and Exchange Commission thereunder.


                                       Yours very truly,

                                       KAUFMAN & CANOLES, P.C.
