                           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 $463,150, such
Member would receive Class B Common Stock in an amount equal to the product of
(i) 24,377 (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 463,150. 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 463,150. As a
result, the Member in this example would receive 316 shares of Class B Common
Stock, plus $2,169.63 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 326 specialist and hospital based 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
                                      S-7
 

<PAGE>
Doctors Health and individual Members after consummation of the Merger, the
Board of Directors of Medtrust determined that the Merger was fair to and in the
best interests of the Members. Moreover, the Medtrust Board determined that
Medtrust should proceed with the Merger at this time.
     THE MEDTRUST BOARD BELIEVES THAT THE MERGER AGREEMENT AND THE MERGER ARE
ADVISABLE, ARE FAIR TO, AND IN THE BEST INTERESTS OF MEDTRUST AND THE MEMBERS.
THE MEDTRUST BOARD UNAINMOUSLY RECOMMENDS THAT THE MEMBERS VOTE TO APPROVE,
RATIFY AND CONFIRM THE MERGER AGREEMENT AND THE MERGER PROVIDED FOR THEREIN.
DETERMINATION OF THE CONVERSION RATIO
     Each Member's interest shall be converted into a percentage of the Share
Consideration and Cash Consideration to be issued in the Merger equal to a
fraction, the numerator of which is the aggregate initial membership fee paid by
the Member for its approved physicians credentialled by Medtrust and the
denominator of which is the aggregate initial membership fees paid by all
Members then holding Membership interests on behalf of their approved physicians
credentialled by Medtrust. Dues and assessments paid in support of ongoing
operations of Medtrust are excluded from the determination of the Conversion
Ratio. All fractional shares produced using this conversion factor are to be
rounded to the next highest whole share and no fractional shares are to be
issued.
EFFECTIVE DATE OF THE MERGER
     The Effective Date of the Merger Agreement and the Merger shall be as soon
as practicable following the satisfaction or waiver of all of the conditions to
closing. Medtrust and Doctors Health may agree that the Effective Date will
occur on another date. On the Effective Date, Doctors Health and Medtrust will
prepare and execute appropriate Articles of Merger, and will file them with the
Virginia Corporation Commission.
EXCHANGE PROCEDURE
     Membership interests will be automatically cancelled upon consummation of
the Merger without further act or submission or documentation by the Members. As
soon as practicable following the Effective Date, Doctors Health will deliver a
form of Letter of Transmittal to each Member. Each Member shall be required to
sign and return the Letter of Transmittal to Kaufman & Canoles. Certificates for
the Share Consideration and checks for the Cash Consideration shall be delivered
at the Closing to Kaufman & Canoles, as counsel for Medtrust. Kaufman & Canoles
shall deliver the respective certificates together with checks for the Cash
Consideration promptly to the address of record of each Medtrust Member upon
receipt of the Letter of Transmittal.
BUSINESS OF DOCTORS HEALTH AND MEDTRUST PENDING THE MERGER
     Pursuant to the Merger Agreement, each of Medtrust and Doctors Health has
made certain covenants relating to the conduct of business pending consummation
of the Merger. Among other things, Medtrust has agreed (except as otherwise
contemplated by the Merger Agreement or with the written consent of Doctors
Health) not to: (i) conduct its business other than in the ordinary and unsual
course; (ii) pay dividends; or (iii) increase any salaries or employee benefits,
except for certain increases in the ordinary course of business and certain
changes required by law or to satisfy pre-existing contractual obligations.
     On November 15, 1996, Medtrust and Doctors Health entered into the
Management Agreement pursuant to which Doctors Health provides certain
management, administrative and support services to Medtrust and Medtrust has
designated Doctors Health as its exclusive and preferred provider of Managed
Care contracts. In particular, Doctors Health has agreed to administer
Medtrust's quality assurance; and utilization management programs, provide third
party administration, collection and coordination of benefit services. The
Management Agreement also provides that Doctors Health will reimburse Medtrust
for its operating expenses commencing on November 1, 1996 and will reimburse
Medtrust for the base salaries and corporate payroll taxes of Drs. Marcus and
Wiederhorn at the rate of $100,000 and $36,650 per year, respectively,
commencing November 15, 1996.
     The Management Agreement provides that Medtrust must implement procedures
to comply with regulatory requirements to recruit PCPs to enter into Exclusive
Participation Agreements or become employees of Core Medical Groups affiliated
with Doctors Health, and to assist Doctors Health in the development of a
Medtrust network of participating physicians and other health care providers.

     Pursuant to these employment agreements, each of the executives has agreed
to maintain the confidentiality of certain information pertaining to the

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.
OPERATIONS OF DOCTORS HEALTH VIRGINIA AFTER THE EFFECTIVE DATE
     After the Effective Date, Doctors Health Virginia will (i) seek to preserve
and enhance the relationships with primary care physicians and specialists
developed by Medtrust and (ii) develop an Integrated Health Care Delivery System
in Northern Virginia. Development of the health care system will include
recruiting PCPs, specialists and other health care providers to transfer certain
assets of medical practices to Doctors Health, enter into exclusive managed care
contracting arrangements or enter into other contractual arrangements for the
delivery of medical services under Doctors Health's Global Capitated
Contracts.

                               VOTING INFORMATION
PROXY SOLICITATION
     This Proxy Statement/Prospectus Supplement and the accompanying proxy
material are furnished in connection with the solicitation of proxies by the
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 449 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
 

<PAGE>
of regulatory approvals required in order to consummate the Merger, including
the registration fee of the Commission, the filing fees in respect of state
"blue sky" laws. The parties do not expect to pay compensation for the
solicitation of proxies (but reserve the right to do so if necessary to obtain
the votes necessary). In addition to solicitation of proxies by mail, proxies
may be solicited personally or by telephone or telegram by directors, officers,
and employees of Medtrust without additional compensation to them.
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 449 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 123 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

     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.

                        DOCTORS HEALTH OF VIRGINIA, INC.

                       CONVERSION OF MEMBERSHIP INTERESTS
     SECTION 3.1. CONVERSION OF MEMBERSHIP INTERESTS. The manner and basis of
converting the membership interests of Medtrust shall be as follows:
          (a) 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").
          (b) 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.
          (c) 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.
          (d) 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.
          (e) 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.
          (f) 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

non-transferable.
     SECTION 4.3. CHARTER DOCUMENTS. A true and complete copy of the articles of
incorporation and by-laws of Medtrust are attached hereto as Exhibit G.
     SECTION 4.4. BINDING OBLIGATION; CONSENTS; LITIGATION. The execution and
delivery of this Agreement by Medtrust does not, and the consummation of the
transactions contemplated hereby will not, violate (i) any provision of the
articles of incorporation or by-laws of Medtrust or (ii) any provision of, or
result in a breach of any of the terms or provisions of, or result in the
acceleration of 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 the satisfaction of the condition described in
Section 10.5 hereof (the "Special Meeting"). Medtrust has full power, authority
and legal right to enter into this Agreement and, upon appropriate vote of its
Members in accordance with law, to 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.
     SECTION 4.5. 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.
     SECTION 4.6. 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.
     SECTION 4.7. TAX MATTERS.
          (a) 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.
          (b) 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.
          (c) 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.

<PAGE>
   
          (d) 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.
     SECTION 4.8. 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 the date of the Medtrust Financial Statements, (iii)
indebtedness, liabilities and obligations listed on Schedule 4.8 hereto, and 
(iv) liabilities incurred in connection with the performance of this Agreement.
     SECTION 4.9. INSURANCE. All significant policies of insurance, together
with the premiums currently paid thereon, providing for business interruption,
personal, employee, product or public liability coverage with respect to the
business of Medtrust are described on Schedule 4.9. The copies of such policies
which have 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.
     SECTION 4.10. FINDERS OR BROKERS. Medtrust has not utilized the services of
any investment banker, broker, finder or intermediary in connection with the
transactions contemplated hereby who might be entitled to a fee or commission in
connection with this Agreement or upon consummation of the transactions
contemplated hereby.
     SECTION 4.11. EMPLOYEE BENEFITS. Except for those plans set forth in
Schedule 4.11, Medtrust currently does not have, or has never had, an employee
benefit plan, including, without limitation, any plan, agreement or arrangement
relating to deferred compensation, pension, profit sharing, retirement income or
other benefits, stock purchase, stock ownership and stock option plan, stock
appreciation rights, bonus, severance arrangement, health and welfare benefits,
insurance benefits or any other employee benefits or fringe benefit plan.
Medtrust does not participate in, or contribute to, nor has Medtrust ever
participated in or contributed to, any multi-employer plan within the meaning of
ERISA Section 4001(a)(3), nor does or will Medtrust have, now or in the future,
any multi-employer plan withdrawal liability under Subtitle E of Part IV of
ERISA.
     SECTION 4.12. EMPLOYMENT MATTERS. Except as set out in Schedule 4.12, there
are no oral or written employment contracts or pension, bonus, profit sharing,
stock option, life, health, retirement, welfare, or other agreements or
arrangements providing for employee remuneration or benefits to which Medtrust
is a party or by which it is bound. To the knowledge of Medtrust, no person
(including, but 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 which 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
or pay in lieu of vacation or time off, other than that earned in respect of the
current fiscal year, or (iv) any violation of any statute, ordinance or
regulation relating to minimum wages or maximum hours of work.

<PAGE>
   
     SECTION 4.13. 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.
     SECTION 4.14. LITIGATION.
          (a) Except as set forth on Schedule 4.14, there is no (i) action,
     suit, claim, proceeding or investigation pending or, to the knowledge of

     assets or properties or the business of Medtrust or the transactions
     contemplated by this Agreement (including inquiries as to the qualification

     any basis for any of the foregoing. There are no pending actions, suits,
     claims or proceedings brought by Medtrust against others.
          (b) Medtrust 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. 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.
          (c) Medtrust knows of no pending or threatened action, suit,
     proceeding, investigation, order or injunction before or by any court or

reflect and provide adequate reserves in respect of all known liabilities of DHS
in accordance with GAAP, including all known contingent liabilities as of their
respective dates, and (iii) present fairly the financial condition of DHS at

          (b) 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

<PAGE>
   
     returns. DHS does not have any tax liability for which no tax reserve has
     been made in respect of any jurisdiction in 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.
          (b) 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.
          (c) 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.
          (d) 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

arising out of or based upon any of such policies of insurance, and, so far as
is known to DHS 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 DHS is in compliance with
all conditions contained therein.
     SECTION 5.12. NO MATERIAL ADVERSE CHANGE. Since the date of the DHS Balance

     SECTION 5.13. REQUIRED CONSENTS. There have been or will be timely filed,
given, obtained or taken all applications, notices, consents, approvals, orders,
registrations, qualifications, waivers or other actions of any kind required by
virtue of the execution and delivery of this Agreement by DHS or Sub or the
consummation by DHS or Sub of any of the transactions contemplated hereby.
     SECTION 5.14. DISCLOSURE REGISTRATION STATEMENT. The Securities Act
Registration Statement, the Prospectus (as defined in Section 6.1(b) of the
Agreement), and any post-effective amendment thereto, on the date on which the
Securities Act Registration Statement (or the post-effective amendment thereto)

Medtrust promptly after it receives notice thereof, of the times when the

suspension of the qualification of the shares of DHS Common Stock issuable in
connection with the Merger for offering or sale in any jurisdiction, of the
initiation or threat of any proceeding for any such purpose, or of any request
by the SEC for the amendment or supplement of the Securities Act Registration
Statement or for additional information. DHS has made all filings with the SEC
that it has been required to make under the Exchange Act (collectively 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

purposes of this Agreement, the term "Stock" shall include (i) beneficial

(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

(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.

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,
(C) with respect to the Series B Investor, shall constitute an Involuntary
Transfer of the Series B Preferred Stock, the Warrant or the Class C Common
Stock, as the case may be, and (D) with respect to the Series C Investor, shall
constitute an Involuntary Transfer of the Series C Preferred Stock, the Option
or the Class C Common Stock, as the case may be. If any Stockholder has actual
knowledge of an Involuntary Transfer by a Stockholder of his or its Stock, such
Stockholder shall give written notice to such effect to DHS, and the giving of
such written notice shall constitute the occurrence of such event for purpose of
the time period set forth in this Section 4(d).
     (e) PAYMENT UPON TERMINATION OF EMPLOYMENT OF MANAGEMENT STOCKHOLDER OTHER
THAN RIFKIN OR KIMMEL. If the employment of a Management Stockholder other than
Rifkin or Kimmel with DHS is terminated, then the Management Stockholders whose
employment with DHS has not been terminated shall have the option, for a period
of sixty (60) days from the date of such termination, to purchase (in such
proportions as they shall agree upon or, if they cannot agree, in proportion to
their ownership of DHS Class A Common Stock other than the stock of the
terminated Management Stockholder) and, if such option is accepted, such
terminated Management Stockholder shall sell all of the shares of Stock held by
                                      B-3

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

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
interest under the Promissory Note issued by the Series A Investor to DHS), or
otherwise make provision for the payment of such dividends that is acceptable to
the Series A Investor, in its reasonable discretion, (B) the Series B Investor

Notwithstanding the foregoing, in the event DHS has paid the Series C Investor
as set forth in this paragraph prior to the consummation of a Qualified Public
Offering on or before August 30, 1998 as defined in the Articles of Amendment
and Restatement dated September 4, 1996, then on or before the consummation of a
Qualified Public Offering on or before August 30, 1998 (at a price per share not
less than the weighted average price paid or to be paid by the Series C Investor
for all shares of Series C Preferred Stock then oustanding) the Series C
Investor shall pay DHS an amount equal to the amount of dividends and interest
paid to the Series C Investor pursuant to this Section.
     (f) TERMINATION OF EMPLOYMENT, DEATH, DISABILITY OF RIFKIN AND KIMMEL.
          (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

Offering on or before August 30, 1998 as defined in the Articles of Amendment
and Restatement dated September 4, 1996, then on or before the consummation of a
Qualified Public Offering on or before August 30, 1998 (at a price per share not
less than the weighted average price paid or to be paid by the Series C Investor
for all shares of Series C Preferred Stock then oustanding) the Series C
Investor shall pay DHS an amount equal to the amount of dividends and interest
paid to the Series C Investor pursuant to this Section.
     (g) PRICE ADJUSTMENTS FOLLOWING A CHANGE IN CONTROL OF DHS. If the
employment of a Management Stockholder other than Rifkin or Kimmel with DHS is
terminated pursuant to the provisions in Section 4(e)(ii)(C) or (D) above, and
there occurs a Change in Control of DHS within the first twenty-four months
following the date of such termination, DHS agrees to pay or cause to be paid to
such terminated Management Stockholder (or to his heirs, 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.

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

     Management Offered Stock; and (D) the Management Stockholder who desires to
     transfer the Management Offered Stock complies with the terms of this
     Section 5(c)(v), then all of the Management Offered Stock remaining unsold
     pursuant to the rights of refusal contained in this Section 5(c) may be
     sold by the selling Management Stockholder to the third party named in the
     Management Stockholder's Offer within a period of thirty (30) days after
     the expiration of the fifteen (15) day period provided in Section 5(c)(iv).
     Such remaining Management Offered Stock may be transferred to the third
     party named in the Management Stockholder's Offer; provided that (X) such

     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

     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

     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

     upon written notification to the selling holder of Remaining Preferred
     Offered Stock, at the price and upon the terms provided in the Convertible

     Preferred Stock desires to purchase the Remaining Preferred Offered Stock,

     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

     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

     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

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.
                                      B-13
 

<PAGE>
     (d) Each of the Management Stockholders and DHS hereby agree that the
provisions of this Section 11 shall be deemed to be amendments to each
Management Stockholder's respective DHS Employment Agreement, and hereby becomes
a part thereof.
     (e) For purposes of this Section 11, an equity financing shall include any
transaction in which Capital Stock of DHS is issued in return for cash.
     12. SEVERABILITY. It is the express intention of the parties that the
agreements contained herein shall have the widest application possible. If any
agreement contained herein is found by a court having jurisdiction to be
unreasonable in scope or character, the agreement shall not be rendered
unenforceable thereby, but the parties shall in good faith negotiate a
modification to the agreement that preserves the essence of the agreement of the
parties contained herein with retroactive effect to render such agreement
reasonable and such agreement shall be enforced as thus modified. If the court
having jurisdiction will not review the agreement, then the parties shall
mutually agree to a revision having an effect as close as permitted by law to
the provision declared unenforceable. The parties further agree that in the
event a court having jurisdiction determines, despite the express intent of the
parties, that any portion of any covenant or agreement contained herein is not
enforceable, the remaining provisions of this Agreement shall nonetheless remain
valid and unenforceable.
     13. ENDORSEMENT OF CERTIFICATE. Upon the execution of this Agreement, each
certificate of Stock of DHS now registered in the name of a Stockholder and
subject hereto shall be endorsed by the Secretary of Company as follows:
          "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.
