Item 5.  Other Events

                  On July 7, 1997, Doctors Health, Inc., a Maryland corporation
(the "Registrant"), entered into a Preferred Stock Purchase Agreement, as
amended on July 15, 1997 (the "Preferred Stock Purchase Agreement"), with The
Beacon Group III - Focus Value Fund, L.P. ("Beacon") pursuant to which the
Registrant agreed to sell and Beacon agreed to purchase three million
(3,000,000) shares of the Registrant's Series D Convertible Preferred Stock for
a purchase price of $30 million, subject to the terms and conditions thereof.
The Registrant closed the transaction on July 15, 1997, with an initial purchase
of two million (2,000,000) shares for $20 million. A subsequent purchase is
expected to take place on or before June 30, 1998 of an additional one million
(1,000,000) shares for $10 million subject to the satisfaction of certain
contingencies or conditions precedent by such date as provided in the Preferred
Stock Purchase Agreement, some of which are outside of the control of the
Registrant.

         Upon the issuance of the full 3,000,000 shares of Series D Preferred
Stock to Beacon, Beacon will own 100% of the Registrant's issued and outstanding
Series D Preferred Stock and approximately 28.8% of the issued and outstanding
capital stock of the Registrant, on a fully diluted basis.

         In connection with the issuance of its Series D Preferred Stock to
Beacon pursuant to the Preferred Stock Purchase Agreement, the Registrant
amended its Amended and Restated Articles of Incorporation (the "Restated
Articles") to, among other things, (a) authorize 5,750,000 shares of a new class
of stock designated as Series D Convertible Preferred Stock, (b) amend or revise
certain of the terms and conditions of its currently authorized and issued
Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, and
Series C Convertible Preferred Stock, (c) increase the size of its Board of
Directors from nineteen to twenty members, (d) elect two of Beacon's designees
to the Registrant's Board of Directors and Executive Committee, (e) modify the
composition and authority of the Registrant's Executive Committee, and (f)
change the name of the Registrant to "Doctors Health, Inc." The Registrant also
agreed to use its best efforts to change is state of incorporation from Maryland
to Delaware within sixty days of the closing of the initial purchase
transaction, subject to the approval of the Registrant's Board of Directors and
stockholders.

         The Series D Preferred Stock issued to Beacon is senior to all other
classes of the Registrant's capital stock with respect to payment of dividends
and distributions and liquidation rights. The Series D Preferred Stock also is
subject to redemption by the Registrant at the election of the holder of the
Series D Preferred Stock at $10 per share, plus accrued but unpaid dividends,
after five years from the issuance date of the Series D Preferred Stock and is
convertible at an adjustable rate into the Registrant's Class C Common Stock at
the option of the holder of the Series D Preferred Stock and automatically upon
a qualifying initial public offering of the Registrant.

         The number of shares of Class C Common Stock issuable upon conversion
of the Series D Preferred Stock is subject to adjustment pursuant to two stock
adjustment agreements between the Registrant and Beacon. The first stock
adjustment agreement provides for an upward or downward adjustment in the number
of shares issuable to Beacon based upon the Medicare Medical Loss Ratio and the
number of Medicare enrollees in the Registrant's Medicare global risk service
agreements with health maintenance organizations and other payors. Pursuant to
the first agreement, the number of shares issuable to Beacon could be reduced to
2,727,272 shares of Class C Common Stock or increased to 5,454,000 shares of
Class C Common Stock. The second stock adjustment agreement provides that it
will supersede the first stock adjustment agreement if the 105th U.S. Congress
makes certain changes in the Medicare program to reduce payments to health
maintenance organizations and medical management companies such as the
Registrant. Pursuant to the second stock adjustment agreement, the number of
shares issuable to Beacon could be reduced to 2,727,272 shares of Class C Common
Stock or increased to 7,500,000 shares of Class C Common Stock. The second stock
adjustment letter is subject to the approval of the Executive Committee of the
Registrant. Certain members of the Registrant's management have agreed to
indemnify and hold Beacon harmless in the event the Executive Committee fails to
approve the second stock adjustment agreement.


<PAGE>

         In connection with the transactions contemplated by the Preferred Stock
Purchase Agreement, the Registrant modified the composition and authority of the
Executive Committee of its Board of Directors. The Executive Committee is
comprised of seven members (two Beacon directors, one Series C Preferred
Director, three physician directors, and the Registrant's Chief Executive
Officer). To the extent permitted by law, the authority of the Board to act on
all matters is vested in and exercised by the Executive Committee. In the event
of certain default situations related to the Registrant's not meeting certain
targets with respect to its net income and its medical loss ratio, Beacon has
the right to take control of the Executive Committee and the Board of Directors.

         In connection with Beacon's investment in the Registrant, the
Registrant also entered into, among other agreements, (a) a Shareholders' and
Voting Agreement, which supersedes the Registrant's current Stockholders
Agreement and provide for certain restrictions on the sale and transfer of all
classes of the Registrant's capital stock, and (b) a Registration Rights
Agreement with Beacon which provides Beacon with certain rights to have the
Registrant register with the Securities and Exchange Commission Beacon's shares
of Series D Preferred Stock for resale.

         On July 9, 1997, the Registrant entered into a Stock Purchase
Agreement, as amended on July 15, 1997 (the "Stock Purchase Agreement") by and
among UniversityCare, L.L.C. ("UniversityCare"), Genesis Health Ventures, Inc.
("Genesis"), and Med-Lantic Management Services, Inc. ("Med-Lantic"), and closed
the transactions contemplated by the Stock Purchase Agreement on July 15, 1997.
Pursuant to the Stock Purchase Agreement and related transactions, (i) Genesis,
the holder of the Registrant's Series C Preferred Stock, assigned and delegated
to UniversityCare all of Genesis' rights and obligations under that certain
Purchase Agreement dated May 2, 1997, which provided for the purchase by Genesis
from Med-Lantic of all 355,556 shares of the Registrant's Series B Preferred
Stock held by Med-Lantic (the "Med-Lantic Shares"); (ii) UniversityCare
purchased from Med-Lantic the Med-Lantic Shares at a purchase price of $11.25
per share; (iii) the Registrant issued and delivered to Med-Lantic 60,290 shares
of the Registrant's Series B Preferred Stock, which constituted the accrued and
unpaid dividends, and interest, on the Med-Lantic Shares (the "Dividend Shares")
and the Registrant issued and delivered 22,222 shares of the Registrant's Series
B Preferred Stock to H.C. Wainwright & Co., Inc. as reimbursement for certain
investment advisory services and related expenses (the "Expense Shares"); and
(iv) the Dividend Shares and the Expense Shares were transferred to
UniversityCare for a purchase price of $11.25 per share. As a result of these
transactions, UniversityCare is the holder of 438,068 shares of the Registrant's
Series B Preferred Stock, which constitute all of the issued and outstanding
shares of Series B Preferred Stock of the Registrant.

                  The Corporation is authorized to issue 68,438,068 shares of
capital stock, of which 20,700,000 shares are Class A Common Stock, par value of

Common Stock, par value of $0.01 per share (the "Class B Common Stock"),
29,050,000 shares are Class C Common Stock, par value of $0.01 per share (the

("Series D Preferred Stock" and in combination with any of Series A Preferred

pursuant to Subsection A.4 is $94,275,765.

                  The stockholders of the Corporation shall be entitled to vote
on such matters as specifically provided herein or as otherwise required by the
MGCL. The preferences, voting powers, restrictions, limitations as to dividends,
rights and qualifications of Common Stock and Preferred Stock are as follows:

                  A.       COMMON STOCK.

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

                  1.       Voting Rights.

                  (a) General Provisions. Except as otherwise provided herein,
every holder of Common Stock shall be entitled to cast, in person or by proxy,
one vote for each share of Common Stock held of record by such holder on all
matters to be voted on by stockholders. The holders of shares of Common Stock
shall vote together with the holders of shares of Preferred Stock on all matters
submitted to a vote of

                                       2

<PAGE>

stockholders and not as a separate series or class, except as otherwise provided
herein.

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

                  (c) Class B Common Stock. The holders of shares of Class B
Common Stock, voting separately as a class, shall be entitled to elect eight
directors of the Corporation (the "Class B Common Directors"). The affirmative
vote of a majority of the shares of Class B Common Stock represented in person
or by proxy at a meeting at which a quorum of Class B Common Stock is present
shall be sufficient to approve any matter with respect to which said holders are
entitled to vote; provided, however, that the affirmative vote of a plurality of
all votes cast shall be sufficient to elect a Class B Common Director. 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, voting as a separate
class, may remove any Class B Common Director at any time and from time to time
with or without cause, by the affirmative vote of a majority of all of the votes
entitled to be cast for the election of a Class B Common Director, and may elect
a successor to fill any resulting vacancies for the remainder of the term of
such director. If any Class B Common Director shall cease to be a director for
any reason (including death, resignation, removal or any other cause), the
vacancy shall be filled by a vote of the remaining Class B Common Directors
(unless, with respect to removal, the holders of Class B Common Stock have
elected a successor Class B Common Director pursuant to the provisions hereof).
If there are no such remaining directors, then upon a call of a special meeting
of holders of Class B

                                       3

<PAGE>

Common Stock, by any such holder, the vacancy shall be filled by the vote of the
holders of Class B Common Stock, voting separately as a class.

                  (d)      Class C Common Stock.

                  (i) Upon conversion of all of the shares of Series A Preferred
Stock then outstanding into shares of Class C Common Stock ("Converted Series A
Stock"), the holders of Converted Series A Stock ("Converted Series A
Stockholders"), voting separately as a sub-class, shall be entitled to elect one
Director of the Corporation ("Converted Series A Director").

                  (ii) Upon conversion of all of the shares of Series B
Preferred Stock then outstanding into shares of Class C Common Stock ("Converted
Series B Stock"), the holders of shares of Converted Series B Stock ("Converted
Series B Stockholders"), voting separately as a sub-class, shall be entitled to
elect one Director of the Corporation ("Converted Series B Director").

                  (iii) Upon conversion of all of the shares of Series C
Preferred Stock then outstanding into shares of Class C Common Stock ("Converted
Series C Stock"), the holders of Converted Series C Stock ("Converted Series C
Stockholders"), voting separately as a sub-class, shall be entitled to elect two
Directors of the Corporation ("Converted Series C Directors").

                  (iv) Upon conversion of all of the shares of Series D
Preferred Stock then outstanding into shares of Class C Common Stock ("Converted
Series D Stock"), the holders of Converted Series D Stock ("Converted Series D
Stockholders"), voting separately as a sub-class, shall be entitled to elect two
Directors of the Corporation ("Converted Series D Directors").

                  (v) It is the intent of this Subsection that upon conversion
of all of the shares of Preferred Stock then outstanding into shares of Class C
Common Stock, the holders of shares of Class C Common Stock, voting separately
as sub-classes, shall be entitled to elect in the aggregate six Directors
thereafter (all such directors being hereinafter referred to as the "Class C
Common Directors").

                  (vi) The affirmative vote of a majority of the shares of Class
C Common Stock represented in person or by proxy at a meeting at which a quorum
of Class C Common Stock is present shall be sufficient to approve any matter
with respect to which said holders are entitled to vote, except for matters
relating to the election or removal of directors.

                  (vii) When Converted Series A Stockholders, Converted Series B
Stockholders, Converted Series C Stockholders or Converted Series D Stockholders
vote on the election of Converted Series A Directors, Converted Series B
Directors, Converted Series C Directors or Converted Series D Directors,
respectively, the affirmative vote of a plurality of all votes cast shall be
sufficient to elect a Converted Series A Director, Converted Series B Director,
Converted Series C Directors or

                                       4

Converted Series D Director, as the case may be. Each share of Converted Series
A Stock, Converted Series B Stock, Converted Series C Stock and Converted Series
D Stock, as the case may be, may be voted for as many individuals as there are
Converted Series A Directors, Converted Series B Directors, Converted Series C
Directors and Converted Series D Directors, respectively, to be elected thereby.

                  (viii) At any annual meeting or upon a call of a special
meeting of holders of Converted Series A Stock, Converted Series B Stock,
Converted Series C Stock or Converted Series D Stock by holders of not less than
25% of the shares of Converted Series A Stock, Converted Series B Stock,
Converted Series C Stock or Converted Series D Stock, as the case may be, then
outstanding, Converted Series A Stockholders, Converted Series B Stockholders,
Converted Series C Stockholders or Converted Series D Stockholders, as the case
may be, may remove any Converted Series A Director, Converted Series B Director,
Converted Series C Director or Converted Series D Director, respectively, at any
time and from time to time with or without cause, voting separately as a
sub-class, by the affirmative vote of 80% of all of the votes entitled to be
cast for the election of a Converted Series A Director, Converted Series B
Director, Converted Series C Director or Converted Series D Director, as the
case may be, and may elect a successor to fill any resulting vacancies for the
remainder of the term of such Director.

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

                  (x) If the Converted Series A Director or Converted Series B
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 holders of Converted Series A Stock or Converted Series B Stock, as the
case may be, voting separately as a sub-class.

                  2. Dividends. Subject to the provisions of law and these
Articles, dividends may be declared and paid on Common Stock at such time and in
such amounts as the Board may deem advisable; provided that, in all events, no
dividends shall be paid with respect to shares of Common Stock until such time
as all of the then outstanding Preferred Stock has been either redeemed by the
Corporation or converted into shares of Common Stock as provided herein, and, in
connection with

                                       5

<PAGE>

such redemption or conversion, all accrued and unpaid dividends on the Preferred
Stock shall have been paid in full.

                  3. Liquidation Rights. In the event of the dissolution,
liquidation or winding up of the Corporation, whether voluntary or involuntary,
after payment or provision for payment of the debts and other liabilities of the
Corporation and the preferential amounts required to be paid to the holders of
Preferred Stock as provided in these Articles, each share of Common Stock shall
be entitled to share ratably with all other shares of Common Stock in the
remaining net assets of the Corporation.

                  4. Conversion of Class A Common Stock, Class B Common Stock
and Class C Common Stock. Immediately prior to the consummation of any firm
commitment, underwritten initial public offering of Common Stock pursuant to an
effective registration statement under the Securities Act of 1933, as amended,
(i) each share of Class A Common Stock, Class B Common Stock and Class C Common
Stock shall be converted, without any action on the part of the holder thereof
or the Corporation, into an identical share of Class A Common Stock, (ii) all
references in these Articles to Class A Common Stock, Class B Common Stock and
Class C Common Stock, respectively, shall be deemed to refer to Class A Common
Stock, and (iii) all special rights granted to the holders of Class A Common
Stock, Class B Common Stock, Class C Common Stock, Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock hereunder shall cease and
terminate. At least 20 days prior written notice of the date fixed and place
determined for conversion shall be sent by first class mail, postage prepaid, to
the address of every holder of shares of Common Stock as shown in the records of
the Corporation. On or before the date fixed for conversion, each holder of
shares of Common Stock shall surrender the Certificates representing such shares
to the Corporation at the place designated in such notice and shall thereafter
receive certificates for the number of full shares of Class A Common Stock to
which such holder is entitled.

                  5. Certain Permitted Redemptions. The Corporation shall not
repurchase any shares of its outstanding Common Stock without the consent of the
holders of a majority of the holders each series of Preferred Stock voting
separately as a class on as converted basis except as follows:

                  (a) a repurchase of shares of Class A Common Stock owned by
any Management Stockholder as and to the extent required (or permitted with the
approval of the Board of Directors) by such Management Stockholder's Management
Employment Agreement or the Shareholders' and Voting Agreement dated July 15,
1997 (the "Shareholders Agreement") by and among the Corporation and certain of
its stockholders;

                  (b) a repurchase of shares of Common Stock owned by any
employee of the Corporation or physician affiliated with the Company, as
provided in any employment, stock grant or physician participation or similar
agreement approved

                                       6

<PAGE>

between the Corporation and/or any of its affiliates and such employee, the
terms of which have been approved by the Executive Committee (as defined in
ARTICLE V hereof), upon such employee's or physician's death, disability,
termination of employment, or otherwise; and

                  (c) a repurchase of shares of Class B Common Stock issued by
the Corporation to Medical Holdings Limited Partnership (the "LP") upon the
termination of the status of any physician as a limited partner of the LP (a
"Physician Interest Holder") in the amount deemed necessary by the Board of
Directors at such time to ensure that the withdrawal of such Physician Interest
Holder increases the percentage ownership interests in the Corporation of all
other stockholders of the Corporation to the same extent that the indirect
percentage ownership interests in the Corporation of the remaining Physician
Interest Holders are increased. Such repurchase shall be for a repurchase price,
if any, equal to the amount that the Corporation requires the LP to pay to such
withdrawing Physician Interest Holder upon his termination.

                  (a) Whenever any action described herein requires the action
of holders of a series of Preferred Stock, such action shall be deemed to have
occurred upon the approval of holders of a majority (or such higher vote as may
be required elsewhere herein) of the then issued and outstanding shares of such
series of Preferred Stock at a duly convened meeting of such stockholders or by
their written consent in accordance with the then applicable provisions of the
MGCL, and the

                                       8

<PAGE>

Corporation, in undertaking any action with respect to such holders, shall be
entitled to rely upon a certificate signed by such holders to that effect.

                  (b) So long as any shares of a series of Preferred Stock are
outstanding, the Corporation shall not without first obtaining the approval (by
vote or written consent) of the holder or holders of at a majority of the then
outstanding shares of such series of Preferred Stock:

                  (i) alter or change the rights, preference or privileges of

of Preferred Stock; or

                  (iii) authorize the issuance of, issue, or sell any additional

                  3. Dividends. No dividends shall be declared or paid upon, nor

any other class or series of stock of, or equity interest in, the Corporation or
any Subsidiary, without the consent of each of the directors elected pursuant to
the terms of these Articles by the holders of Preferred Stock senior in rank,
with respect to dividends, to such stock on which such dividend or other
distribution would be paid.

                  4.       Redemption.

                  (a) If provision for payment of the redemption price for
shares of Preferred Stock redeemed hereunder has been made by the Corporation,
so long as there is no payment default with respect to deferred portions of such
redemption price, then (i) no dividends shall accrue on the shares of Preferred
Stock to be redeemed after the applicable redemption date, and (ii) as of such
redemption date, all rights of the respective holders of such shares to be
redeemed shall cease, other than the right to receive the applicable redemption
price upon presentation and surrender of the respective certificates
representing such shares.

                  (b) If the redemption price for any shares to be redeemed
pursuant to these Articles cannot be paid in full because the Corporation is
prohibited by law from making such payment, then those funds that are legally
available will be used to pay, first, accrued but unpaid interest, if any,
second, accrued but unpaid dividends and, third, the applicable redemption price
for the maximum possible number of shares of Preferred Stock that may be
redeemed with such funds (on a series-by-series basis, in accordance with rank)
ratably among the holders thereof, determined by multiplying the total number of
shares of Preferred Stock to be redeemed by a fraction, the numerator of which
shall be the total number of such shares then held by each such

                                       9

<PAGE>

holder and the denominator of which shall be the total number of such shares
then outstanding. Shares of Preferred Stock not redeemed shall remain
outstanding, and the holders thereof shall be entitled to all rights and
preferences provided herein with respect to such shares; provided, however,
that, at any time thereafter that additional funds of the Corporation are
legally available for the redemption of additional shares of Preferred Stock,
such funds will be used, at the end of the next succeeding fiscal quarter, to
redeem the balance of such shares, or such portion thereof for which funds are
then legally available in accordance with the general provisions of this
Subsection B.4(b). If, at any time, fewer than the total number of shares of
Preferred Stock represented by any certificate are redeemed, a new certificate
representing the number of unredeemed shares of Preferred Stock shall be issued
to the holder thereof without cost to such holder within three Business Days
after surrender by the holder thereof of the certificate representing the
redeemed and nonredeemed shares of Preferred Stock.

                  (c) If the Corporation for any reason fails to redeem any
shares of Preferred Stock in accordance with this ARTICLE IV on or prior to the
applicable redemption date specified herein, then, notwithstanding anything to
the contrary contained in these Articles, the Corporation may not incur any
additional indebtedness without first obtaining the prior written consent of the
holders of the Preferred Stock to be redeemed, voting as a single class on an as
converted basis, unless the proceeds of such indebtedness are used to pay all
overdue redemption payments in respect of Preferred Stock, including payments of
accrued but unpaid dividends or interest.

                  (d) No shares of any class of stock of, or equity interest in,
the Corporation or any Subsidiary, shall be redeemed, retired, purchased or
otherwise acquired by the Corporation, except purchases of the Corporation's
interests in a Subsidiary at the time of its organization, without the consent
of the holders of a majority of the then outstanding shares of each series of
Preferred Stock then outstanding that, at the time of such redemption, is senior
in rank, with respect to redemptions, to the stock to be redeemed.
Notwithstanding the foregoing, the Corporation may (i) effect repurchases
permitted by clauses (a) through (c) of Subsection A.5, (ii) cause the
redemption of shares of capital stock of, or equity interests in, its
wholly-owned Subsidiaries without the separate consent of such directors and
(iii) effect redemptions as required by Subsection C.3(b).


                  5.       Conversion.

                  (a) Notwithstanding anything in these Articles to the
contrary, the Corporation shall not be required to give effect to any adjustment
in any Conversion Ratio unless and until the net effect of one or more
adjustments (each of which shall be carried forward), determined as provided
below, shall have resulted in a change of such Conversion Ratio by at least
one-tenth of one share of Common Stock, and when the cumulative net effect of
more than one adjustment so determined shall be to change such Conversion Ratio
by at least one-tenth of one share of Common Stock, such change in such
Conversion Ratio shall thereupon be given effect.

                                       10

<PAGE>

                  (b) For purposes of adjusting a Conversion Ratio pursuant to
Subsections C.4(c), D.4(c), E.4(c) or F.4(c) (with respect to conversion of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock, respectively), the aggregate consideration receivable
by the Corporation in connection with the issuance of shares of Common Stock
and/or Common Stock Equivalents shall be deemed to be equal to the sum of the
aggregate offering price (before deduction of underwriting discounts or
commissions and expenses payable to third parties, if any) of all such Common
Stock and/or Common Stock Equivalents plus the minimum aggregate amount, if any,
payable to the Corporation upon conversion, exchange or exercise of any such
Common Stock Equivalents. If the consideration received by the Corporation in
connection with the sale or issuance of shares of Common Stock (or Common Stock
Equivalents) consists, in whole or in part, of property other than cash or its
equivalent, the value of such property shall be the Fair Market Value thereof.

                  (c) For purposes of adjusting a Conversion Ratio pursuant to
Subsections C.4(c), D.4(c), E.4(c) or F.4(c) (with respect to conversion of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock, respectively), the number of shares of Common Stock at
any time outstanding shall mean the aggregate of all shares of Common Stock then
outstanding (other than any shares of Common Stock then owned or held by or for
the account of the Corporation) treating for purposes of this calculation all
Common Stock Equivalents then outstanding as having been converted, exchanged or
exercised.

                  (d) If the Corporation shall take a record of the holders of
its Common Stock for the purpose of entitling them to receive a dividend or
other distribution and shall thereafter, and before such dividend or
distribution is paid or delivered to stockholders entitled thereto, legally
abandon its plan to pay or deliver such dividend or distribution, then no
adjustment in the relevant Conversion Ratio then in effect shall be made by
reason of the taking of such record, and any such adjustment previously made as
a result of the taking of such record shall be reversed.

                  (e) The issuance of certificates for shares of Common Stock
upon conversion of Preferred Stock shall be made without charge to the holders
thereof for any issuance tax in respect thereof, provided that the Corporation
shall not be required to pay any tax which may be payable in respect of any
transfer involved in the issuance and delivery of any certificate in a name
other than that of the holder of the Preferred Stock that is being converted.

                  (f) The Corporation shall at no time close its transfer books
against the transfer of any Preferred Stock, or of any shares of Common Stock
issued or issuable upon the conversion of any shares of Preferred Stock, in any
manner that interferes with the timely conversion of such Preferred Stock,
except as may otherwise be required to comply with applicable securities laws.


                                       11

<PAGE>

                  (g) The holders of shares of Preferred Stock requesting
conversion of shares into shares of Class C Common Stock shall send a written
notice to the Corporation requesting such conversion and accompanied by the
certificates therefor, duly endorsed for transfer, to the principal office of
the Corporation or the transfer agent, if any, for the Preferred Stock.
Conversion of Preferred Stock pursuant to this ARTICLE IV shall be effective as
of the close of business on the date of receipt of such notice, and the holders
of such converted Preferred Stock shall be treated for all purposes as the
record holders of the shares of Class C Common Stock into which such Preferred
Stock is converted as of such date. As soon as practicable thereafter, the
Corporation shall issue and deliver to such holders a certificate or
certificates for the number of such shares of Class C Common Stock to which they
are entitled as a result of such conversion.

                  (h) The Corporation shall not, by amendment of these Articles
or through any reorganization, recapitalization, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms and conditions
of these Articles to be observed or performed hereunder by the Corporation, but
will at all times in good faith assist in the carrying out of all the provisions
of Subsections C.4, D.4, E.4 and F.4 and in the taking of all such action as may
be necessary or appropriate in order to protect the conversion rights of the
holders of Preferred Stock against impairment.

                  (i) The Corporation shall at all times reserve and keep
available for issuance upon the conversion of Preferred Stock, free from any
preemptive rights, such number of its authorized but unissued shares of Class C
Common Stock as will from time to time be necessary to permit the conversion of
all outstanding shares of Preferred Stock into shares of Class C Common Stock,
and shall take all action required to increase the authorized number of shares
of Class C Common Stock if necessary to permit the conversion of all outstanding
shares of Preferred Stock.

                  (j) The provisions of Subsections C.4, D.4, E.4 and F.4 shall
not give, or be deemed to give, the Corporation the power or authority to issue
any shares of its capital stock or other securities, or to take any other
action, where such action is otherwise prohibited by another provision hereof.

                  (k) If the Corporation shall be a party to any transaction
including without limitation, a merger, consolidation, sale of all or
substantially all of the Corporation's assets or a reorganization,
reclassification or recapitalization of the capital stock of the Corporation,
but excluding any transaction for which provision for adjustment of the
applicable Conversion Ratio is otherwise made in Subsection C.4 (with respect to
Series A Preferred Stock), Subsection D.4 (with respect to Series B Preferred
Stock), Subsection E.4 (with respect to Series C Preferred Stock), Subsection
F.4 (with respect to Series D Preferred Stock), (each of the foregoing being
referred to as a "Transaction"), in each case, as a result of which shares of
Common Stock are converted into the right to receive stock, securities or other
property (including cash or any combination thereof), each share of Preferred
Stock shall

                                       12

<PAGE>

thereafter be convertible into the number of shares of stock or other securities
or property to which a holder of the number of shares of Common Stock of the
Corporation deliverable upon conversion of such Preferred Stock would have been
entitled upon such Transaction; and, in any such case, appropriate adjustment to
the applicable Conversion Ratio (as determined by the Board (including the
Series D Preferred Directors)) shall be made in the application of the
provisions set forth in Subsection C.4, Subsection D.4, Subsection E.4,
Subsection F.4 with respect to the rights and interest thereafter of the holders
of Preferred Stock, to the end that the provisions set forth in Subsection C.4,
Subsection D.4, Subsection E.4, Subsection F.4 shall thereafter be applicable,
as nearly as reasonably may be, in relation to any shares of stock or other
property thereafter deliverable upon the conversion of Preferred Stock. The
Corporation shall not effect any Transaction (other than a consolidation or
merger in which the Corporation is the continuing corporation) unless prior to
or simultaneously with the consummation thereof the Corporation, or the
successor corporation or purchaser, as the case may be, shall provide in its
charter that each share of Preferred Stock shall be converted into such shares
of stock, securities or property as, in accordance with the foregoing
provisions, each such holder is entitled to receive. The provisions of this
Subsection B.5(k) shall apply similarly to successive Transactions.

                  6.       Liquidation Rights.

                  (a) The Corporation shall provide at least 30 days prior
written notice of any liquidation, dissolution or winding up of the affairs of
the Corporation giving rise to rights under Subsections C.5, D.5, E.5 and F.5
(liquidation rights of the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock, respectively), stating a
payment date, the amount of the liquidation payments payable hereunder, if any,
and the place such liquidation payments shall be payable, by first class mail,
postage prepaid, to each holder of Preferred Stock at his address as shown on
the records of the Corporation.

                  (b) Unless waived by the affirmative vote of the holders of at
least a majority of each series of Preferred Stock, voting as separate series,
the sale, lease or exchange (for cash, shares of stock, securities or other
consideration) of all or substantially all the property and assets of the
Corporation or the merger or consolidation of the Corporation into or with any
other corporation, or the merger or consolidation of any other corporation into
or with the Corporation, shall be deemed to be a dissolution, liquidation or
winding-up, voluntary or involuntary, for the purposes of Subsections C.5, D.5,
E.5 and F.5.

                  7.       Notice of Certain  Events.  Without  limiting  the
rights of the  holders of Series D Preferred  Stock,  or the  obligations  of
the Corporation, set forth in Subsection F.1, if, at any time while any shares
of a series of Preferred Stock are outstanding:
                                       13
<PAGE>
                  (a)      the  Corporation  shall declare a dividend or any
other  distribution on any of its securities that are junior or pari passu in
rank to such series of Preferred Stock;

                  (b) the Corporation shall authorize the issuance to the
holders of its Common Stock, of Common Stock Equivalents, or rights or warrants
to subscribe for or purchase shares of its Common Stock or of any other
subscription rights or warrants;

                  (c) the Corporation shall authorize any  reorganization,
reclassification  or recapitalization of any of its securities that are junior
or pari passu in rank to such series of Preferred Stock;

                  (d) the Corporation shall authorize the consolidation or
merger of the Corporation into or with any other person, the sale or transfer of
a substantial portion of its capital stock, business or assets to another
person, or any other similar business combination or transaction; or

                  (e) the Corporation shall authorize the dissolution,
liquidation or winding up, voluntary or involuntary, of the Corporation; then
the Corporation shall promptly deliver to the holders of shares of such series
of Preferred Stock at their last addresses as shown on the books of the
Corporation, at least 15 days before the date hereinafter specified (or the
earlier of the dates hereinafter specified, in the event that more than one date
is specified), a notice describing such event and stating (x) the date on which
a record is to be taken for the purpose of such dividend, distribution, rights
or warrants, or, if a record is not to be taken, the date as of which the
holders of the Corporation's Common Stock, Common Stock Equivalents, rights or
warrants of record to be entitled to such dividend, distribution, rights or
warrants are to be determined, or (y) the date on which any such
reclassification, reorganization, recapitalization, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of record of
securities of the Corporation that are junior or pari passu in rank to such
series of Preferred Stock shall be entitled to exchange securities of the
Corporation that are junior or pari passu in rank to such series of Preferred
Stock for securities or other property (including cash), if any, deliverable
upon such reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up.

                  8. Certain  Remedies.  Any  registered  holder of a series of
Preferred  Stock may  proceed to protect  and enforce its rights and the rights
of any other holders of such series of Preferred Stock with any and all remedies
available at law or in equity.

                  9. Reports as to Adjustments. Upon any adjustment of a
Conversion Ratio then in effect and any increase or decrease in the number of
shares of Common Stock issuable upon the operation of the conversion provisions
set forth in this Articles
                                       14

<PAGE>

IV, then, and in each such case, the Corporation shall promptly deliver to the
registered holders of the affected series of Preferred Stock as shown on the
books of the Corporation a copy of a certificate signed by the President or a
Vice President and by the Treasurer or an Assistant Treasurer or the Secretary
or an Assistant Secretary of the Corporation setting forth in reasonable detail
(a) the event or facts requiring the adjustment, (b) the Conversion Ratio with
respect to such series of Preferred Stock then in effect following such
adjustment, (c) the increased or decreased number of shares of Class C Common
Stock issuable upon the conversion of such series of Preferred Stock as provided
in this ARTICLE IV and (d) the method of calculation used to determine the
foregoing adjustment.

                  10. Reacquired Shares of Preferred Stock. Any shares of
Preferred Stock converted, redeemed, purchased or otherwise acquired by the
Corporation in any manner whatsoever shall be retired and canceled promptly
after the acquisition thereof. None of such reacquired shares of Preferred Stock
shall be reissued by the Corporation.

                  C.       SERIES A PREFERRED STOCK.

                  Series A Preferred Stock shall rank, with respect to dividend
rights, redemption rights and rights on liquidation, winding-up and dissolution
(i) junior to Series D Preferred Stock ("Series A Senior Securities"), (ii) pari
passu to Series C Preferred Stock and (iii) senior to all classes of Common
Stock and Series B Preferred Stock and to each other class or series of capital
stock issued by the Corporation or established by the Board that by its terms is
junior to the Series A Preferred Stock ("Series A Junior Securities").

                  1.       Voting Rights.

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

                  (b) Series A Preferred Stock Directors. The holders of shares
of Series A Preferred Stock, voting separately as a class, shall be entitled to
elect one director of the Corporation (the "Series A Preferred Stock Director").
Where the holders of Series A Preferred Stock vote as a class, the affirmative
vote of a majority

                                       15

<PAGE>

of the shares of Series A Preferred Stock represented in person or by proxy at a
meeting at which a quorum of Series A Preferred Stock is present shall be
sufficient to approve any matter with respect to which said holders are entitled
to vote; provided, however, that the affirmative vote of a plurality of all
votes cast in person or by proxy by the holders of Series A Preferred Stock
shall be sufficient to elect the Series A Preferred Stock Director. The holders
of Series A Preferred Stock, at any properly called annual or special meeting or
upon a call of a special meeting of holders of Series A Preferred Stock by
holders of not less than 25% of the shares of Series A Preferred Stock then
outstanding, voting separately as a class, may remove the Series A Preferred
Stock Director at any time and from time to time, by the affirmative vote of 80%
of all votes entitled to be cast for the election of the Series A Preferred
Stock Director, and may elect a successor to fill any resulting vacancies for
the remainder of the term of the Series A Preferred Stock Director. If the
Series A Preferred Stock Director shall cease to be a director for any reason
(including death, resignation, removal or any other cause) the vacancy shall be
filled by the vote of the holders of Series A Preferred Stock, voting separately
as a class.

                  2.       Dividends.

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

                  (b) Payment of Dividends Before April 1, 2000. Dividends and
interest accrued on or with respect to accrual dates occurring prior to April 1,
2000 shall be payable (either in connection with a redemption of Series A
Preferred Stock or a liquidation payment, or otherwise) prior to April 1, 2000
only upon (i) the dissolution, liquidation or winding up of the Corporation as
herein provided or (ii) the redemption or conversion of Series A Preferred
Stock. If such dividends and interest are not paid on or prior to April 1, 2000
because there has been no liquidation, redemption or conversion on or prior to
April 1, 2000, the amount of all such accrued dividends and interest payments
shall thereafter be an unsecured obligation of the Corporation, payable in equal
quarterly installments over three (3) years and shall bear interest at the rate,
and be payable, as set forth with respect to dividend payments in Subsection
C.2(c) below.

                  (c) Payment of Dividends Commencing April 1, 2000. Commencing
April 1, 2000, cash dividends shall accrue at a per annum rate equal to 100
basis points over The Wall Street Journal Prime Rate as of the last Business Day
prior to April 1, 2000 on the original issue price of each share of Series A
Preferred Stock outstanding (whether or not such dividends have been earned or
declared by the

                                       16

<PAGE>

Board), and shall be payable in equal quarterly installments on the first day of
each month of April, July, October and January. All such accrued dividends shall
be declared by the Board and shall be payable to each holder of Series A
Preferred Stock on each scheduled quarterly date if, at the time of payment,
funds for the full payment of such quarterly dividend on all shares of Series A
Preferred Stock then outstanding are legally available therefor under the laws
of the State of Maryland as then in effect.

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

                  3.       Redemption.

                  (a)      Redemptions Initiated by the Corporation.

                  (i) The Corporation may, out of funds legally available
therefor, after delivery of prior written notice (which may be delivered at any
time commencing on the fifth anniversary of the Issue Date of the Series D
Preferred Stock), redeem all, but not less than all, of the outstanding Series A
Preferred Stock (other than Series A Preferred Stock with respect to which
redemption has been required by the holders thereof pursuant to Subsection
C.3(b) hereof) in exchange for a price equal to the sum of the issue price of
such Series A Preferred Stock plus all accumulated accrued but unpaid dividends
thereon, including accrued but unpaid interest on such dividends, whether or not
such dividends have been declared by the Corporation, through the Series A
Redemption Date, subject to any right of set off of the Corporation under these
Articles.

                  (ii) As used in this Subsection C.3, the applicable "Series A
Redemption Date" shall be the later of (x) 20 calendar days after delivery of
the redemption notice delivered in accordance with the provisions of this
ARTICLE IV and (y) 10 days after determination of Fair Market Value of the
Series A Preferred Stock to be redeemed pursuant to Subsection C.3(b). On the
applicable Series A Redemption Date, the Corporation shall pay by wire transfer
the redemption price for the shares redeemed hereunder.

                                       17
<PAGE>

                  (b)      Redemptions Initiated by Holders of Series A
Preferred Stock.

                  (i) Upon the occurrence of a "Special Redemption Event" as set
forth in Section 12.8 of that certain Financing Transaction Agreement between
the Corporation, the original holder of Series A Preferred Stock and others,
dated as of February 24, 1995, and only so long and to the extent the original
holder of Series A Preferred Stock continues to hold shares of Series A
Preferred Stock, the original holder of Series A Preferred Stock shall have a
period of sixty days from the occurrence of such Special Redemption Event to
request the Corporation to redeem, and the Corporation shall redeem, out of any
funds legally available therefor, all (but not less than all) of the then issued
and outstanding shares of Series A Preferred Stock held thereby, at an amount
per share equal to the sum of the issue price plus all accrued and unpaid
interest and dividends thereon (subject to any right of set off of the
Corporation referred to in Subsection C.2(d) hereof), whether or not such
dividends have actually been declared. The Corporation shall be entitled to
satisfy any redemption obligations owing under this Subsection C.3(b) by
delivering to the original holder of Series A Preferred Stock a promissory note
with a term of 24 full months from the date of such request (collectively, the
"Maturity Date"). Compound interest shall accrue on any such note at the rate of
6.5% per annum. The principal amount of such note shall be amortized ratably on
a 60 month basis. Accrued and unpaid interest shall be payable, together with
equal monthly installments of principal, on the fifth day of each month
following the issuance of such note, with a final payment of all accrued and
unpaid interest plus all remaining unpaid principal due on the Maturity Date.
Such note will be repayable without premium, will be subordinated to all then
existing or thereafter created indebtedness of the Corporation and will contain
certain such customary default and other clauses as are customary in promissory
notes of such type and amount.

                  (ii) If the Corporation elects to issue any Series A Adverse
Securities (as hereafter defined), then the holders of Series A Preferred Stock
shall be entitled, by delivery of written notice to the Corporation at the
principal office of the Corporation within 90 days after the date of issuance of
such Series A Adverse Securities, to request that the Corporation redeem, and
the Corporation shall redeem, all but not less than all of the issued and
outstanding shares of Series A Preferred Stock held by holders requesting
redemption. Such redemption payment shall be made in cash prior to or
contemporaneously with such issuance if a request for redemption is made 30 or
more days prior to the date specified for issuance by the Corporation in its
notice of issuance, and otherwise no sooner than 180 days after the date of such
request, but in all events within one year of such request. The redemption price
payable to holders of Series A Preferred Stock in connection with the redemption
of shares of such stock pursuant to this clause (ii) shall be an amount per
share equal to the greatest of (A) the purchase price per share of Series A
Adverse Securities to be paid, by the purchaser of such Series A Adverse
Securities, (B) the then Fair Market Value of such share of Series A Preferred
Stock and (C) the product of 1.5 times the sum of the liquidation preference of
such shares of Series A Preferred Stock to the date such shares are actually
redeemed, determined in accordance with the provisions of

                                       18

<PAGE>

Subsection C.5 hereof. Interest shall accrue at a rate of 6.5% per annum on the
Fair Market Value of the shares of Series A Preferred Stock with respect to
which redemption is sought pursuant to this clause (ii) from the date notice of
such redemption is provided to the Corporation until full payment is made of all
amounts payable pursuant to this clause (ii). As used in this clause (ii), the
term "Series A Adverse Securities" shall mean any capital stock of the
Corporation that is issued to any person or entity that has legitimate business
interests that are materially adverse to the legitimate business interests of
St. Joseph Medical Center, Inc., Towson, Maryland, or its affiliated entities in
the Baltimore, Maryland metropolitan area (a "Series A Adverse Holder")
determined in accordance with the provisions of this clause. The Corporation
shall provide written notice of its intention to issue capital stock to a
purchaser or purchasers other than holders of Series A Preferred Stock at least
30 days prior to such issuance. If the holders of a majority of the then issued
and outstanding shares of Series A Preferred Stock, voting as a single class,
shall have determined by affirmative vote that such purchaser or purchasers are
Series A Adverse Holders, the Corporation shall suspend the sale and issuance of
such Series A Adverse Securities and submit the question as to whether such
purchaser or purchasers are Series A Adverse Holders to arbitration under the
expedited procedures set forth herein. Such arbitration shall be conducted by
three arbitrators, two of whom (the "Party Designated Arbitrators") shall be
selected by the parties, and the third of whom shall be a "neutral Arbitrator"
selected by the Party Designated Arbitrators. The corporation shall designate
its Party Designated Arbitrator by written notice to the holders of Series A
Preferred Stock, and within five days thereafter, such holders of Series A
Preferred Stock shall designate their Party Designated Arbitrator. Within five
days thereafter, the two Party Designated Arbitrators shall agree upon and
appoint a Neutral Arbitrator, who shall be an attorney experienced in the health
care business. The only issue to be determined in the arbitration shall be
whether the proposed purchaser or purchasers of Series A. Junior Securities is a
Series A Adverse Holder. The arbitration shall be concluded within 60 days after
the date of the Corporation's written notice. The determination of the
arbitrators so appointed shall be final and conclusive upon the parties. If the
arbitrators hereunder determine that the proposed purchaser of purchasers are
Series A Adverse Holders (1) the Corporation may nonetheless proceed to issue
such shares to such purchaser or purchasers upon delivery of written notice to
that effect to the holders of Series A Preferred Stock no later than 30 days
prior to the date such issuance is consummated, and (2) the holders of Series A
Preferred Stock shall thereupon become entitled to exercise their rights to
require the Corporation to redeem all, but not less than all, of the issued and
outstanding shares Series A Preferred Stock pursuant to the provisions of this
clause (ii).

                  (iii) Subject to the provisions of Subsection F.2(e) and
F.3(c) the holder or holders of at least 50% of the outstanding shares of Series
A Preferred Stock may, at their option, at any time, or from time to time, from
and after the fifth anniversary of the Issue Date of the Series D Preferred
Stock require the Corporation to redeem, out of funds legally available
therefor, all of the outstanding shares of Series A Preferred Stock (including
shares not held by such holder or holders). The

                                       19

<PAGE>

redemption price payable upon any redemption pursuant to this Subsection
C.3(b)(iii) shall be the greater of (x) an amount per share equal to $5.00 plus
accrued but unpaid dividends thereon (including accrued but unpaid interest on
such dividends) and (y) the then Fair Market Value of the redeemed Series A
Preferred Stock.

                  (c) Redemption of Series A Junior Securities. Notwithstanding
any other provision of these Articles to the contrary and except for Section
IV.D(3)(b), unless and until all of the issued and outstanding Series A
Preferred Stock has been either redeemed or converted in accordance with this
Section C, the Corporation may not and shall not redeem, repurchase or otherwise
make any payment in connection with the acquisition, redemption, repurchase or
cancellation of any Series A Junior Securities or any stock options or similar
rights with respect to any Series A Junior Securities, and the Corporation shall
cause all corporations, partnerships, limited liability companies and other
entities controlled, directly or indirectly, by the Corporation to refrain from
engaging in such transactions.

                  (d) Special Provisions with Respect to Subscription
Receivables.

                  (i) If the Corporation elects to defer receipt of all or any
portion of any scheduled payment of principal due and payable to the Corporation
under any promissory note of any holder of Series A Preferred Stock in favor of,
and delivered to, the Corporation in consideration for the issuance by the
Corporation of Series A Preferred Stock to such holder (each, a "Series A
Deferred Payment Amount"), then the Corporation may redeem, in its discretion,
upon at least 30 days prior written notice to the holders of Series A Preferred
Stock as of the Series A Redemption Date set forth in such notice, a number of
shares of Series A Preferred Stock from the maker of such note determined by
dividing the aggregate amount of all then outstanding Series A Deferred Payment
Amounts by $5.00. The redemption price per share payable pursuant to this
Subsection C.3(d) shall be equal to $5.00 for each share so redeemed and shall
be set off against such Series A Deferred Payment Amounts.

                  (ii) To the extent that shares of Series A Preferred Stock
referred to in Subsection C.3(d)(i) are not converted into shares of Class C
Common Stock pursuant to the provisions of Subsection C.4(a), the Corporation
may redeem the remaining outstanding shares of Series A Preferred Stock upon at
least ten days prior written notice to the holders of Series A Preferred Stock.
The redemption price for such shares shall be equal to the amount of, and shall
be paid by cancellation of, the full unpaid principal amount of the promissory
note, if any, delivered by the holder of such shares to the Corporation in
partial consideration for the purchase and issuance of such shares.

                  4.       Conversion Rights.

                  (a) In General. Upon the consummation of an IPO, each share of
Series A Preferred Stock shall automatically be converted into shares of Class C
Common Stock at the then effective Series A Conversion Ratio (as determined in

                                       20

<PAGE>

accordance with the provisions of Paragraph (c) of this Subsection C.4). In
addition, at the option of the holder of any Series A Preferred Stock, such
holder shall have the right, at any time and from time to time prior to the
consummation of an IPO, by written notice to the Corporation, to convert any and
all shares of Series A Preferred Stock owned by such holder into shares of Class
C Common Stock at the then effective Series A Conversion Ratio.

                  (b)      Adjustments  to the Series A Conversion  Ratio.  The
Series A Conversion  Ratio shall be subject to adjustment  from time to time as
follows:

                  (i) In case the Corporation shall at any time or from time to
time after the Issue Date of the Series A Preferred Stock (the "Series A Issue
Date") (A) pay a dividend, or make a distribution, on the outstanding shares of
Common Stock in shares of Common Stock, (B) subdivide the outstanding shares of
Common Stock, (C) combine the outstanding shares of Common Stock into a smaller
number of shares or (D) issue by reclassification of the shares of Common Stock
any shares of capital stock of the Corporation, then, and in each such case, the
Series A Conversion Ratio in effect immediately prior to such event or the
record date therefor, whichever is earlier, shall be adjusted so that the holder
of any shares of Series A Preferred Stock thereafter surrendered for conversion
shall be entitled to receive the number of shares of Common Stock or other
securities of the Corporation that such holder would have owned or have been
entitled to receive after the happening of any of the events described above,
had such shares of Series A Preferred Stock been surrendered for conversion
immediately prior to the happening of such event or the record date therefor,
whichever is earlier. An adjustment made pursuant to this clause (i) shall
become effective (x) in the case of any such dividend or distribution,
immediately after the close of business on the record date for the determination
of holders of shares of Common Stock entitled to receive such dividend or
distribution, or (y) in the case of such subdivision, reclassification or
combination, at the close of business on the day upon which such corporate
action becomes effective. No adjustment shall be made pursuant to this clause
(i) in connection with any transaction to which Subsection B.5(k) applies.

                  (ii) Except with respect to Excluded Securities, in case the
Corporation shall issue shares of Common Stock or Common Stock Equivalents after
the Series A Issue Date at a price per share (or having a conversion, exercise
or exchange price per share) less than the Series A Issue Price (as defined
below) per share of Common Stock as of the date of issuance of such shares or of
such convertible securities, then, and in each such case, the Conversion Ratio
shall be adjusted so that the holder of each share of Series A Preferred Stock
shall be entitled to receive, upon the conversion thereof, the number of shares
of Common Stock determined by multiplying (A) the Series A Conversion Ratio in
effect on the day immediately prior to such date by (B) one plus a fraction, the
numerator of which shall be the amount of the Series D Spread (as defined in
Subsection F.4(b)) and the denominator of which shall be the Series D Issue
Price (as defined in Subsection F.4(c)). An adjustment made pursuant to this
clause (ii) shall be made on the next Business Day following the date on which
any such issuance is made and shall be

                                       21

<PAGE>

effective retroactively to the close of business on the date of such issuance.
Upon the expiration of any unexercised Common Stock Equivalents for which an
adjustment has been made pursuant to this clause (ii), the adjustment (and any
subsequent adjustments) shall forthwith be reversed to effect such rate of
conversion as would have been in effect at the time of such expiration or
termination had such Common Stock Equivalents, to the extent outstanding
immediately prior to such expiration or termination, never been issued. No
adjustment shall be made pursuant to this clause (ii) in connection with any
transaction to which Subsection B.4(k) applies.

                  (c) As used in this Subsection C.4, the term "Series A
Conversion Ratio" means the Conversion Ratio applicable with respect to Series A
Preferred Stock. The Series A Conversion Ratio shall initially equal one and
shall be subject to adjustment as provided in Subsection C.4(b). As used in this
Subsection C.4, the term "Series A Issue Price" means $5.00 per share (subject
to adjustment for stock dividends, stock splits, reclassifications and other
transactions that require an adjustment pursuant to Subsection C.4(b)).

                  (d) If any event occurs as to which, in the opinion of the
Executive Committee, the provisions of this Subsection C.4 are not strictly
applicable or, if strictly applicable, would not fairly accomplish the intent of
these provisions, the Executive Committee shall make an adjustment in the
application of such provisions, in accordance with such intent, so as to
accomplish such intent.

                  5.       Liquidation Rights.

                  (a) Upon any liquidation, dissolution or winding up of the
affairs of the Corporation, whether voluntary or involuntary, the holders of
shares of the Series A Preferred Stock shall be entitled to receive out of the
assets of the Corporation available for distribution to stockholders, before any
distribution or payment shall be made in respect of the holders of shares of
Series A Junior Securities, a liquidating distribution in an amount equal to the
greater of (i) the Fair Market Value per share of Series A Preferred Stock or
(ii) the sum of $5.00 plus an amount equal to all accrued but unpaid dividends
thereon (including any interest accrued but unpaid with respect to such
dividends) to the date fixed for such distribution or payment; provided,
however, that immediately prior to making any payments pursuant to this
Subsection C.5(a), the Corporation shall redeem the maximum number of shares of
Series A Preferred Stock redeemable pursuant to Subsection B.3(d)(i) to the
effect that upon consummation of such redemption, there shall be no outstanding
Series A Deferred Payment Amount; provided, further, however, that no
liquidating distribution shall be paid in respect of Series A Preferred Stock
unless and until all amounts due to holders of Series A Senior Securities as a
liquidating distribution pursuant to these Articles shall have been fully paid.

                  (b) If, upon any such liquidation, dissolution or winding up
of the affairs of the Corporation, the assets of the Corporation available for
distributions under this Subsection C.5 shall be insufficient to permit the
payment in full to the holders of Series A Preferred Stock of the amounts to
which they are entitled

                                       22

<PAGE>

hereunder, then all of such available assets shall be distributed to the holders
of shares of Series A Preferred Stock ratably in proportion to the liquidation
payment otherwise due under Subsection C.5(a) to each such holder, and no
amounts shall be distributed in respect of any class or series of capital stock
of the Corporation ranking junior to the Series A Preferred Stock with respect
to liquidation rights until all amounts distributable to holders of Series A
Preferred Stock hereunder have been distributed.

                  (c) After the payment to the holders of the Series A Preferred
Stock of the full preferential amounts provided for in this Subsection C.5, the
holders of Series A Preferred Stock as such shall have no right or claim to any
of the remaining assets of the Corporation.

                  D.       SERIES B PREFERRED STOCK.

                  Series B Preferred Stock shall rank, with respect to dividend
rights, redemption rights and rights on liquidation, winding-up and dissolution
(i) junior to Series A Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock and (ii) senior to all classes of Common Stock and to each other
class or series of capital stock issued by the Corporation or established by the
Board that by its terms is junior to the Series B Preferred Stock ("Series B
Junior Securities").

                  1.       Voting Rights.

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

                  (b) Series B Preferred Stock Directors. The holders of shares
of Series B Preferred Stock, voting separately as a class, shall be entitled to
elect one director of the Corporation (the "Series B Preferred Stock Director").
Where the holders of Series B Preferred Stock vote as a class, the affirmative
vote of a majority of the shares of Series B Preferred Stock represented in
person or by proxy at a meeting at which a quorum of Series B Preferred Stock is
present shall be sufficient to approve any matter with respect to which said
holders are entitled to vote; provided, however, that the affirmative vote of a
plurality of all votes cast in person or by proxy by the holders of Series B
Preferred Stock shall be sufficient to elect the Series B Preferred Stock
Director. The holders of Series B Preferred Stock, at any properly

                                       23

<PAGE>

called annual or special meeting or upon a call of a special meeting of holders
of Series B Preferred Stock by holders of not less than 25% of the shares of
Series B Preferred Stock then outstanding, voting separately as a class, may
remove the Series B Preferred Stock Director at any time and from time to time,
by the affirmative vote of 80% of all votes entitled to be cast for the election
of a Series B Preferred Stock Director, and may elect a successor to fill any
resulting vacancies for the remainder of the term of the Series B Preferred
Stock Director. If the Series B Preferred Stock Director shall cease to be a
director for any reason (including death, resignation, removal or any other
cause) the vacancy shall be filled by the vote of the holders of Series B
Preferred Stock, voting separately as a class.

                  2.       Dividends.

                  (a) Accrual of Dividends Before April 1, 2000. Beginning as of
December 1, 1995 and prior to April 1, 2000, cash dividends at the rate of $0.90
per share per annum shall accrue on the Series B Preferred Stock (whether or not
earned or declared or payment is legally available therefor) in equal quarterly
installments, commencing on the first day of January 1996, and continuing
thereafter on the first day of each month of April, July, October, January and
shall accrue interest at the rate of 8.0% per annum (based upon a 365 day year)
compounded quarterly on all such unpaid dividend amounts.

                  (b) Payment of Dividends Before April 1, 2000. Dividends and
interest accrued on or with respect to accrual dates occurring prior to April 1,
2000 shall be payable (either as part of a Series B Redemption Price (as defined
below) or liquidation payment, or otherwise) prior to April 1, 2000 only after
all dividends and interest accrued on or with respect to all other series of
Preferred Stock have been fully paid and only upon (i) the liquidation of the
Corporation as herein provided, or (ii) the redemption or conversion of such
shares of Series B Preferred Stock. If such dividends and interest are not paid
on or prior to April 1, 2000 because there has been no liquidation, redemption
or conversion on or prior to April 1, 2000, the amount of all such accrued
dividends and interest payments shall thereafter be an unsecured obligation of
the Corporation, payable in equal quarterly installments over three (3) years
and shall bear interest at the rate, and be payable, as set forth with respect
to dividend payments in Subsection D.2(c) below.

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

                                       24

<PAGE>

other series of Preferred Stock have been fully paid, and (ii) funds for the
full payment of such quarterly dividend on all shares of Series B Preferred
Stock then outstanding are legally available therefor under the laws of the
State of Maryland as then in effect.

                  3.       Redemption.

                  (a)      Redemptions Initiated by the Corporation.

                  (i) The Corporation may, out of funds legally available
therefor, after delivery of prior written notice (which may be delivered at any
time commencing on the fifth anniversary of the Issue Date of the Series D
Preferred Stock), redeem all, but not less than all, of the outstanding Series B
Preferred Stock in exchange for a price equal to the sum of the issue price of
such Series B Preferred Stock plus all accumulated accrued but unpaid dividends
thereon, including accrued but unpaid interest on such dividends, whether or not
such dividends have been declared by the Corporation, through the Series B
Redemption Date, subject to any right of set off of the Corporation under these
Articles.

                  (ii) As used in this Subsection D.3, the "Series B Redemption
Date" shall be 20 calendar days after delivery of the redemption notice
delivered in accordance with the provisions of this ARTICLE IV. On the
applicable Series B Redemption Date, the Corporation shall pay by wire transfer
the redemption price for the shares redeemed hereunder.

                  (b)      Redemptions Initiated by Holders of Series B
Preferred Stock.

                  (i) So long as UniversityCare, LLC, the University of Maryland
Medical System, Inc., or any of their affiliates is a holder of record of any
Series B Preferred Stock at the option of such holder (the "Series B Holder"),
the Series B Preferred Stock shall be redeemed, at a price equal to the lower of
Fair Market Value or $11.25 per share, plus accrued but unpaid dividends, in the
event of the adoption or interpretation of any law or regulation under the
Internal Revenue Code of 1986, as amended, that reasonably may be construed as
prohibiting or otherwise materially adversely affecting the tax exempt status of
the University of Maryland Medical System, Inc. or University Physicians, Inc.
("UPI") due to the continued ownership of the Series B Preferred Stock by
UniversityCare. Such repurchase obligation shall be subject to the following:

                           (A) To be effective,  the Series B Holder must
deliver written notice to the Corporation of its election to require  redemption
of the Series B Preferred Stock within 30 days after such adoption or
interpretation. Such notice shall be accompanied by an opinion of counsel
reasonably acceptable to the Corporation, confirming the adoption or
interpretation of such law or regulation and the applicability to and effect on
the Series B Holder;

                                       25

<PAGE>

                           (B) For a period of thirty days following the
delivery of the opinion described in subsection (A), the Series B Holder shall
use commercially reasonable efforts to sell the Series B Stock to a third party,
which may, but need not include any of the other holders of preferred or common
stock of the Corporation; provided that the term "commercially reasonable" shall
not require the Series B Holder to accept a price lower than $11.25 per share
plus any accrued but unpaid dividends. In the event that the Series B Holder is
unable to find a purchaser acceptable to it and to the Corporation for such
shares within the thirty day period, the Series B Holder shall so notify the
Corporation, and the redemption obligation set forth above shall become
effective, the closing of which redemption shall occur as soon as practicable
following the notification by the Series B Holder of its inability to sell such
shares provided herein.

                  (ii) If the Corporation elects to issue any Series B Adverse
Securities (as hereafter defined), then the holders of Series B Preferred Stock
shall be entitled, by delivery of written notice to the Corporation at the
principal office of the Corporation within 90 days after the date of issuance of
such Series B Adverse Securities, to request that the Corporation redeem, and
the Corporation shall redeem, all but not less than all of the issued and
outstanding shares of Series B Preferred Stock held by holders requesting
redemption. Such redemption payment shall be made in cash prior to or
contemporaneously with such issuance if a request for redemption is made 30 or
more days prior to the date specified for issuance by the Corporation in its
notice of issuance, and otherwise no sooner than 180 days after the date of such
request, but in all events within one year of such request. The redemption price
payable to holders of Series B Preferred Stock in connection with the redemption
of shares of such stock pursuant to this clause (ii) shall be an amount per
share equal to the greatest of (A) the purchase price per share of Series B
Adverse Securities to be paid, by the purchaser of such Series B Adverse
Securities, (B) the then Fair Market Value of such shares of Series B Preferred
Stock and (C) the product of 1.5 times the sum of the liquidation preference of
such shares of Series B Preferred Stock to the date such shares are actually
redeemed, determined in accordance with the provisions of Subsection D.5 hereof.
Interest shall accrue at a rate of 6.5% per annum on the Fair Market Value of
the shares of Series B Preferred Stock with respect to which redemption is
sought pursuant to this clause (ii) from the date notice of such redemption is
provided to the Corporation until full payment is made of all amount payable
pursuant to this clause (ii). As used in this clause (ii), the term "Series B
Adverse Securities" shall mean (i) a teaching hospital affiliated with a college
or a university, located within the State of Maryland; (ii) a person or entity
which has legitimate business interests that are materially adverse to the
legitimate business interests of University of Maryland Medical System, Inc. or
other affiliated providers of institutional medical services located within the
Baltimore metropolitan area; or (iii) any entity that is controlled by, controls
or is under common control with an entity described in either clauses (i) or
(ii) hereof (a "Series B Adverse Holder") determined in accordance with the
provisions of this clause. The Corporation shall provide written notice of its
intention to issue capital stock to a purchaser or purchasers other than holders
of Series B Preferred Stock at least 30 days prior to such issuance. If the

                                       26

<PAGE>

holders of a majority of the then issued and outstanding shares of Series B
Preferred Stock, voting as a single class, shall have determined by affirmative
vote that such purchaser or purchasers are Series B Adverse Holders, the
Corporation shall suspend the sale and issuance of such Series B Adverse
Securities and submit the question as to whether such purchaser or purchasers
are Series B Adverse Holders to arbitration under the expedited procedures set
forth herein. Such arbitration shall be conducted by three arbitrators, two of
whom (the "Party Designated Arbitrators") shall be selected by the parties, and
the third of whom shall be a "Neutral Arbitrator" selected by the Party
Designated Arbitrators. The Corporation shall designate its Party Designated
Arbitrator by written notice to the holders of Series B Preferred Stock, and
within five days thereafter, such holders of Series B Preferred Stock shall
designate their Party Designated Arbitrator. Within five days thereafter, the
two Party Designated Arbitrators shall agree upon and appoint a Neutral
Arbitrator, who shall be an attorney experienced in the health care business.
The only issue to be determined in the arbitration shall be whether the proposed
purchaser or purchasers of Series B Adverse Securities is a Series B Adverse
Holder. The arbitration shall be concluded within 60 days after the date of the
Corporation's written notice. The determination of the arbitrators so appointed
shall be final and conclusive upon the parties. If the arbitrators hereunder
determine that the proposed purchaser or purchasers are Series B Adverse
Holders, (1) the Corporation may nonetheless proceed to issue such shares to
such purchaser or purchasers upon delivery of written notice to that effect to
the holders of Series B Preferred Stock no later than 30 days prior to the date
such issuance is consummated, and (2) the holders of Series B Preferred Stock
shall thereupon become entitled to exercise their rights to require the
Corporation to redeem all, but not less than all, of the issued and outstanding
shares Series B Preferred Stock pursuant to the provisions of this clause (ii).

                  (c) Redemption of Series B Junior Securities. Notwithstanding
any other provision of these Articles to the contrary, unless and until all of
the issued and outstanding Series B Preferred Stock has been either redeemed or
converted in accordance with this Subsection D, the Corporation may not and
shall not redeem, repurchase or otherwise make any payment in connection with
the acquisition, redemption, repurchase or cancellation of any Series B Junior
Securities or any stock options or similar rights with respect to any Series B
Junior Securities, and the Corporation shall cause all corporations,
partnerships, limited liability companies and other entities controlled,
directly or indirectly, by the Corporation to refrain from engaging in such
transactions.

                  4.       Conversion Rights.

                  (a) In General. Upon the consummation of an IPO, each share of
Series B Preferred Stock shall automatically be converted into shares of Class C
Common Stock at the then effective Series B Conversion Ratio (determined in
accordance with the provisions of Subsection D.4(c)). In addition, at the option
of the holder of any Series B Preferred Stock, such holder shall have the right,
at any time and from time to time prior to the consummation of an IPO, by
written notice to the

                                       27

<PAGE>

Corporation, to convert any and all shares of Series B Preferred Stock owned by
such holder into shares of Class C Common Stock at the then effective Series B
Conversion Ratio.

                  (b) Adjustments  to the Series B Conversion  Ratio.  The
Series B Conversion  Ratio shall be subject to adjustment  from time to time as
follows:

                  (i) In case the Corporation shall at any time or from time to
time after the Issue Date of the Series D Preferred Stock (the "Series B
Reference Date") (A) pay a dividend, or make a distribution, on the outstanding
shares of Common Stock in shares of Common Stock, (B) subdivide the outstanding
shares of Common Stock, (C) combine the outstanding shares of Common Stock into
a smaller number of shares or (D) issue by reclassification of the shares of
Common Stock any shares of capital stock of the Corporation, then, and in each
such case, the Series B Conversion Ratio in effect immediately prior to such
event or the record date therefor, whichever is earlier, shall be adjusted so
that the holder of any shares of Series B Preferred Stock thereafter surrendered
for conversion shall be entitled to receive the number of shares of Common Stock
or other securities of the Corporation that such holder would have owned or have
been entitled to receive after the happening of any of the events described
above, had such shares of Series B Preferred Stock been surrendered for
conversion immediately prior to the happening of such event or the record date
therefor, whichever is earlier. An adjustment made pursuant to this clause (i)
shall become effective (x) in the case of any such dividend or distribution,
immediately after the close of business on the record date for the determination
of holders of shares of Common Stock entitled to receive such dividend or
distribution, or (y) in the case of such subdivision, reclassification or
combination, at the close of business on the day upon which such corporate
action becomes effective. No adjustment shall be made pursuant to this clause
(i) in connection with any transaction to which Subsection B.5(k) applies.

                  (ii) Except with respect to Excluded Securities, in case the
Corporation shall issue shares of Common Stock or Common Stock Equivalents after
the Series B Reference Date at a price per share (or having a conversion,
exercise or exchange price per share) equal to or greater than the Series D
Issue Price (as defined in Subsection F.4(c)) but less than the Series B Issue
Price (as defined below) per share of Common Stock as of the date of issuance of
such shares or of such convertible securities, then, and in each such case, the
Conversion Ratio shall be adjusted so that the holder of each share of Series B
Preferred Stock shall be entitled to receive, upon the conversion thereof, the
number of shares of Common Stock determined by multiplying (A) the Series B
Conversion Ratio in effect on the day immediately prior to such date by (B) a
fraction, the numerator of which shall be the sum of (1) the number of shares of
Common Stock outstanding on such date and (2) the number of additional shares of
Common Stock issued or for which the Common Stock Equivalents may convert or be
exercised or exchanged, and the denominator of which shall be the sum of (x) the
number of shares of Common Stock outstanding on such date and (y) the number of
shares of Common Stock which the aggregate consideration receivable by the
Corporation for the total number of shares of Common Stock issued or for which
the Common Stock Equivalents may convert or be exercised

                                       28

<PAGE>

or exchanged would purchase at the Series B Issue Price on such date. Except
with respect to Excluded Securities, in case the Corporation shall issue shares
of Common Stock or Common Stock Equivalents after the Series B Reference Date at
a price per share (or having a conversion, exercise or exchange price per share)
less than the Series D Issue Price (as defined in Subsection F.4(c)) and less
than the Series B Issue Price (as defined below) per share of Common Stock as of
the date of issuance of such shares or of such convertible securities, then, and
in each such case, the Conversion Ratio shall be adjusted so that the holder of
each share of Series B Preferred Stock shall be entitled to receive, upon the
conversion thereof, the number of shares of Common Stock determined by
multiplying (A) the Series B Conversion Ratio in effect on the day immediately
prior to such date by (B) one plus a fraction, the numerator of which shall be
the amount of the Series D Spread (as defined in Subsection F.4(b)) and the
denominator of which shall be the Series D Issue Price (as defined in Subsection
F.4(c)). An adjustment made pursuant to this clause (ii) shall be made on the
next Business Day following the date on which any such issuance is made and
shall be effective retroactively to the close of business on the date of such
issuance. Upon the expiration of any unexercised Common Stock Equivalents for
which an adjustment has been made pursuant to this clause (ii), the adjustment
(and any subsequent adjustments) shall forthwith be reversed to effect such rate
of conversion as would have been in effect at the time of such expiration or
termination had such Common Stock Equivalents, to the extent outstanding
immediately prior to such expiration or termination, never been issued. No
adjustment shall be made pursuant to this clause (ii) in connection with any
transaction to which Subsection B.5 (k) applies.

                  (c) As used in this Subsection D.4, the term "Series B
Conversion Ratio" means the Conversion Ratio applicable with respect to Series B
Preferred Stock. The Series B Conversion Ratio shall initially equal one and
shall be subject to adjustment as provided in Subsection D.4(b). As used in this
Subsection D.4, the term "Series B Issue Price" means $11.25 per share (subject
to adjustment for stock dividends, stock splits, reclassifications and other
transactions that require an adjustment pursuant to Subsection D.4(b)).

                  (d) If any event occurs as to which, in the opinion of the
Executive Committee, the provisions of this Subsection D.4 are not strictly
applicable or, if strictly applicable, would not fairly accomplish the intent of
these provisions, the Executive Committee shall make an adjustment in the
application of such provisions, in accordance with such intent, so as to
accomplish such intent.

                  5.       Liquidation Rights.

                  (a) Upon any liquidation, dissolution or winding up of the
affairs of the Corporation, whether voluntary or involuntary, the holders of
shares of the Series B Preferred Stock shall be entitled to receive out of the
assets of the Corporation available for distribution to stockholders, before any
distribution or payment shall be made in respect of the holders of shares of
Series B Junior Securities, a liquidating

                                       29

<PAGE>

distribution in an amount equal to the greater of (i) the Fair Market Value per
share of Series B Preferred Stock or (ii) the sum of $11.25 plus an amount equal
to all accrued but unpaid dividends thereon (including any interest accrued but
unpaid with respect to such dividends) to the date fixed for such distribution
or payment; provided, however, that no liquidating distribution shall be paid in
respect of Series B Preferred Stock unless and until all amounts due to holders
of Series B Senior Securities as a liquidating distribution pursuant to these
Articles shall have been fully paid.

                  (b) If, upon any such liquidation, dissolution or winding up
of the affairs of the Corporation, the assets of the Corporation available for
distributions under this Subsection D.5 shall be insufficient to permit the
payment in full to the holders of Series B Preferred Stock of the amounts to
which they are entitled hereunder, then all of such available assets shall be
distributed to the holders of shares of Series B Preferred Stock ratably in
proportion to the liquidation payment otherwise due under Subsection D.5(a) to
each such holder, and no amounts shall be distributed in respect of any class or
series of capital stock of the Corporation ranking junior to the Series B
Preferred Stock with respect to liquidation rights until all amounts
distributable to holders of Series B Preferred Stock hereunder have been
distributed.

                  (c) After the payment to the holders of the Series B Preferred
Stock of the full preferential amounts provided for in this Subsection D.5, the
holders of Series B Preferred Stock as such shall have no right or claim to any
of the remaining assets of the Corporation.

                  E.       SERIES C PREFERRED STOCK.

                  Series C Preferred Stock shall rank, with respect to dividend
rights, redemption rights and rights on liquidation, winding-up and dissolution
(i) junior to Series D Preferred Stock ("Series C Senior Securities"), (ii) pari
passu to Series A Preferred Stock and (iii) senior to all classes of Common
Stock and Series B Preferred Stock and to each other class or series of capital
stock issued by the Corporation or established by the Board that by its terms is
junior to the Series C Preferred Stock (collectively, "Series C Junior
Securities").

                  1.       Voting Rights.

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

                                       30

<PAGE>

equal to the full number of shares of Class C Common Stock into which such
holder's Series C Preferred Stock is then convertible.

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

                  2.       Dividends.

                  (a) Accrual of Dividends Before April 1, 2000. Beginning as of
the date shares of Series C Preferred Stock are issued and prior to April 1,
2000, cash dividends shall accrue on shares of Series C Preferred Stock, at the
rate of 8% per annum on the original issue price of each share of Series C
Preferred Stock, beginning on the date of issuance of such shares (whether or
not earned or declared or payment is legally available therefor) and such
dividends, to the extent accrued but unpaid, shall accrue interest at the rate
of 8% per annum (based upon a 365-day year) compounded quarterly on all such
unpaid dividend amounts.

                  (b) Payment of Dividends Before April 1, 2000. Dividends and
interest accrued on or with respect to accrual dates occurring prior to April 1,
2000 shall be payable (either in connection with a redemption of Series C
Preferred Stock or a liquidation payment, or otherwise) prior to April 1, 2000
only upon (i) the dissolution, liquidation or winding up of the Corporation as
herein provided or (ii) the redemption or conversion of Series C Preferred
Stock. If such dividends and interest are not paid on

                                       31

<PAGE>

or prior to April 1, 2000 because there has been no liquidation, redemption or
conversion on or prior to April 1, 2000, the amount of all such accrued
dividends and interest payments shall thereafter be an unsecured obligation of
the Corporation payable in equal quarterly installments over three (3) years and
shall bear interest at the rate, and be payable, as set forth with respect to
dividend payments in Subsection E.2(c) below.

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

                  3.       Redemption.

                  (a)      Redemptions Initiated by the Corporation.

                  (i) The Corporation may, out of funds legally available
therefor, after delivery of prior written notice (which may be delivered at any
time commencing on the fifth anniversary of the Issue Date of the Series D
Preferred Stock), redeem all, but not less than all, of the outstanding Series C
Preferred Stock (other than Series C Preferred Stock with respect to which
redemption has been required by the holders thereof pursuant to Subsection
E.3(b) hereof) in exchange for a price equal to the sum of the issue price of
such Series C Preferred Stock plus all accumulated accrued but unpaid dividends
thereon, including accrued but unpaid interest on such dividends, whether or not
such dividends have been declared by the Corporation, through the Series C
Redemption Date, subject to any right of set off of the Corporation under these
Articles.

                  (ii) As used in this Subsection E.3, the applicable "Series C
Redemption Date" shall be the later of (x) 20 calendar days after delivery of
the redemption notice delivered in accordance with the provisions of this
ARTICLE IV and (y) 10 days after determination of the Fair Market Value of the
Series C Preferred Stock to be redeemed pursuant to Subsection E.3(b). On the
applicable Series C Redemption Date, the Corporation shall pay by wire transfer
the redemption price for the shares redeemed hereunder.

                  (b) Redemptions Initiated by Holders of Series C Preferred
Stock. Subject to the provisions of Subsection F.2 (e) and F.3(c), the holder or
holders of at least 50% of the outstanding shares of Series C Preferred Stock
may, at their option,

                                       32

<PAGE>

at any time, or from time to time, from and after the fifth anniversary of the
Issue Date of the Series D Preferred Stock require the Corporation to redeem,
out of funds legally available therefore, all of the outstanding shares of
Series C Preferred Stock (including shares not held by such holder or holders).
The redemption price payable upon any redemption pursuant to this Subsection
E.3(b) shall be the greater of (x) an amount per share equal to the weighted
average price paid by a holder of Series C Preferred Stock therefor, plus
accrued but unpaid dividends thereon (including accrued but unpaid interest on
such dividends) and (y) the then Fair Market Value of the redeemed Series C
Preferred Stock.

                  (c) Redemption of Series C Junior Securities. Notwithstanding
any other provision of these Articles to the contrary and except for Section
IV.D(3)(b), unless and until all of the issued and outstanding Series C
Preferred Stock has been either redeemed or converted in accordance with this
Section E, the Corporation may not and shall not redeem, repurchase or otherwise
make any payment in connection with the acquisition, redemption, repurchase or
cancellation of any Series C Junior Securities or any stock options or similar
rights with respect to any Series C Junior Securities, and the Corporation shall
cause all corporations, partnerships, limited liability companies and other
entities controlled, directly or indirectly, by the Corporation to refrain from
engaging in such transactions.

                  4.       Conversion Rights.

                  (a) In General. Upon the consummation of an IPO, each share of
Series C Preferred Stock shall automatically be converted into shares of Class C
Common Stock at the then effective Series C Conversion Ratio (as determined in
accordance with the provisions of Subsection E.4(c)). In addition, at the option
of the holder of any Series C Preferred Stock, such holder shall have the right,
at any time and from time to time prior to the consummation of an IPO, by
written notice to the Corporation, to convert any and all shares of Series C
Preferred Stock owned by such holder into shares of Class C Common Stock at the
then effective Series C Conversion Ratio.

                  (b)      Adjustments  to the Series C Conversion  Ratio.  The
Series C Conversion  Ratio shall be subject to adjustment  from time to time as
follows:

                  (i) In case the Corporation shall at any time or from time to
time after the Issue Date of the Series D Preferred Stock (the "Series C
Reference Date") (A) pay a dividend, or make a distribution, on the outstanding
shares of Common Stock in shares of Common Stock, (B) subdivide the outstanding
shares of Common Stock, (C) combine the outstanding shares of Common Stock into
a smaller number of shares or (D) issue by reclassification shares of Common
Stock any shares of capital stock of the Corporation, then, and in each such
case, the Series C Conversion Ratio in effect immediately prior to such event or
the record date therefor, whichever is earlier, shall be adjusted so that the
holder of any shares of Series C Preferred Stock thereafter surrendered for
conversion shall be entitled to receive the number of shares of Common Stock or
other securities of the Corporation that such holder would have

                                       33

<PAGE>

owned or have been entitled to receive after the happening of any of the events
described above, had such shares of Series C Preferred Stock been surrendered
for conversion immediately prior to the happening of such event or the record
date therefor, whichever is earlier. An adjustment made pursuant to this clause
(i) shall become effective (x) in the case of any such dividend or distribution,
immediately after the close of business on the record date for the determination
of holders of shares of Common Stock entitled to receive such dividend or
distribution, or (y) in the case of such subdivision, reclassification or
combination, at the close of business on the day upon which such corporate
action becomes effective. No adjustment shall be made pursuant to this clause
(i) in connection with any transaction to which Subsection B.5(k) applies.

                  (ii) Except with respect to Excluded Securities, in case the
Corporation shall issue shares of Common Stock or Common Stock Equivalents after
the Series C Reference Date at a price per share (or having a conversion,
exercise or exchange price per share) equal to or greater than the Series D
Issue Price (as defined in Subsection F.4(c) but less than the Series C Issue
Price (as defined below) per share of Common Stock as of the date of issuance of
such shares or of such convertible securities, then, and in each such case, the
Conversion Ratio shall be adjusted so that the holder of each share of Series C
Preferred Stock shall be entitled to receive, upon the conversion thereof, the
number of shares of Common Stock determined by multiplying (A) the Series C
Conversion Ratio in effect on the day immediately prior to such date by (B) a
fraction, the numerator of which shall be the sum of (1) the number of shares of
Common Stock outstanding on such date and (2) the number of additional shares of
Common Stock issued or for which the Common Stock Equivalents may convert or be
exercised or exchanged, and the denominator of which shall be the sum of (x) the
number of shares of Common Stock outstanding on such date and (y) the number of
shares of Common Stock which the aggregate consideration receivable by the
Corporation for the total number of shares of Common Stock issued or for which
the Common Stock Equivalents may convert or be exercised or exchanged would
purchase at the Series C Issue Price on such date. Except with respect to
Excluded Securities, in case the Corporation shall issue shares of Common Stock
or Common Stock Equivalents after the Series C Reference Date at a price per
share (or having a conversion, exercise or exchange price per share) less than
the Series D Issue Price (as defined in Subsection F.4(c)) and less than the
Series C Issue Price (as defined below) per share of Common Stock as of the date
of such shares or of such convertible securities, then, and in each such case,
the Conversion Ratio shall be adjusted so that the holder of each share of
Series C Preferred Stock shall be entitled to receive, upon the conversion
thereof, the number of shares of Common Stock determined by multiplying (A) the
Series C Conversion Ratio in effect on the day immediately prior to such date by
(b) one plus a fraction, the numerator of which shall be the amount of the
Series D Spread (as defined in Subsection F.4(b)) and the denominator of which
shall be the Series D Issue Price (as defined in Subsection F.4(c)). An
adjustment made pursuant to this clause (ii) shall be made on the next Business
Day following the date on which any such issuance is made and shall be effective
retroactively to the close of business on the date of such issuance. Upon the
expiration of any unexercised Common Stock Equivalents for which an adjustment
has

                                       34

<PAGE>

been made pursuant to this clause (ii), the adjustment (and any subsequent
adjustments) shall forthwith be reversed to effect such rate of conversion as
would have been in effect at the time of such expiration or termination had such
Common Stock Equivalents, to the extent outstanding immediately prior to such
expiration or termination, never been issued. No adjustment shall be made
pursuant to this clause (ii) in connection with any transaction to which
Subsection B.5(k) applies.

                  (c) As used in this Subsection E.4, the term "Series C
Conversion Ratio" means the Conversion Ratio applicable with respect to Series C
Preferred Stock. The Series C Conversion Ratio shall initially equal 1.25 and
shall be subject to adjustment as provided in Subsection E.4(b). As used in this
Subsection E.4, the term "Series C Issue Price" means $17.50 per share (subject
to adjustment for stock dividends, stock splits, reclassifications and other
transactions that require an adjustment pursuant to Subsection E.4(b)).

                  (d) If any event occurs as to which, in the opinion of the
Executive Committee, the provisions of this Subsection E.4 are not strictly
applicable or, if strictly applicable, would not fairly accomplish the intent of
these provisions, the Executive Committee shall make an adjustment in the
application of such provisions, in accordance with such intent, so as to
accomplish such intent.

                  5.       Liquidation Rights.

                  (a) Upon any liquidation, dissolution or winding up of the
affairs of the Corporation, whether voluntary or involuntary, the holders of
shares of the Series C Preferred Stock shall be entitled to receive out of the
assets of the Corporation available for distribution to stockholders, before any
distribution or payment shall be made in respect of the holders of shares of
Series C Junior Securities, a liquidating distribution in an amount equal to
$17.50 per share, plus an amount equal to all accrued but unpaid dividends
thereon (including any interests with respect to such dividends) to the date
fixed for such distribution or payment; provided, however, that no liquidating
distribution shall be paid in respect of Series C Preferred Stock unless and
until all amounts due to holders of Series C Senior Securities as a liquidating
distribution pursuant to these Articles shall have been fully paid.

                  (b) If, upon any such liquidation, dissolution or winding up
of the affairs of the Corporation, the assets of the Corporation available for
distributions under this Subsection E.5 shall be insufficient to permit the
payment in full to the holders of Series C Preferred Stock of the amounts to
which they are entitled hereunder, then all of such available assets shall be
distributed to the holders of shares of Series C Preferred Stock ratably in
proportion to the liquidation payment otherwise due under Subsection E.5(a) to
each such holder, and no amounts shall be distributed in respect of any Series C
Junior Securities with respect to liquidation rights until all amounts
distributable to holders of Series C Preferred Stock hereunder have been
distributed.

                                       35

<PAGE>

                  (c) After the payment to the holders of the Series C Preferred
Stock of the full preferential amounts provided for in this Subsection E.5, the
holders of Series C Preferred Stock as such shall have no right or claim to any
of the remaining assets of the Corporation.

                  F.       SERIES D CONVERTIBLE PREFERRED STOCK.

                  Series D Preferred Stock shall rank, with respect to dividend
rights, redemption right and rights on liquidation, winding-up and dissolution,
senior to all classes of Common Stock, Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock and to each other class or series
of capital stock hereafter issued by the Corporation or established by the Board
(collectively, "Series D Junior Securities").

                  1.       Voting.

                  (a) General Provisions. Holders of Series D Preferred Stock
shall be entitled to notice of each meeting of all of the Corporation's
stockholders, or any class, subclass, series or subseries thereof. Holders of
Series D Preferred Stock shall vote together with the holders of shares of
Common Stock, Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock on all matters submitted to a vote of stockholders and not as a
separate series or class, except as otherwise provided herein. Except as
otherwise provided herein, on all matters to be voted on by the Corporation's
stockholders, every holder of Series D Preferred Stock shall be entitled to
cast, in person or by proxy, that number of votes equal to the full number of
shares of Common Stock into which such holder's Series D Preferred Stock is
convertible, at the record date for the determination of shareholders entitled
to vote on such matters or, if no such record date is established, at the date
such vote is taken or any written consent of shareholders is solicited.

                  (b) Series D Preferred Directors. Holders of Series D
Preferred Stock, voting as a single class, shall be entitled to elect two
directors of the Corporation (the "Series D Preferred Directors"). Where the
holders of Series D Preferred Stock vote separately as a class, the affirmative
vote of a majority of the shares of Series D Preferred Stock represented in
person or by proxy at a meeting at which a quorum of Series D Preferred Stock is
present shall be sufficient to approve any matter with respect to which said
holders are entitled to vote, including, without limitation election of a Series
D Preferred Director. Holders of Series D Preferred Stock, at any properly
called annual or special meeting or upon a call of a special meeting of holders
of Series D Preferred Stock by holders of not less than 25% of the shares of
Series D Preferred Stock then outstanding, voting separately as a class, may
remove any Series D Preferred Director at any time and from time to time, by the
affirmative vote of 80% of all votes entitled to be cast for the election of a
Series D Preferred Director, and may elect a successor to fill any resulting
vacancies for the remainder of the term of such Series D Preferred Director. If
any Series D Preferred Director shall cease to be a director for any reason
(including death, resignation, removal or any other cause),

                                       36

<PAGE>

the vacancy shall be filled by the affirmative vote of the remaining Series D
Preferred Director (unless, with respect to removal of a Series D Preferred
Director, the holders of Series D Preferred Stock have elected a successor
Series D Preferred Director pursuant to the provisions hereof). If there is no
such remaining Series D Preferred Director, then upon a call of a special
meeting of holders of Series D Preferred Stock by any such holder, the vacancies
shall be filled by the affirmative vote of the holders of Series D Preferred
Stock, voting separately as a class.

                  (c) Actions Requiring Written Approval of Certain Holders of
Series D Preferred Stock. Prior to the consummation of a Qualified IPO,
notwithstanding any other provision of these Articles to the contrary, the
Corporation shall not, and shall not permit any of its Subsidiaries to, directly
or indirectly, take any of the following actions without first obtaining the
approval (by vote or written consent) of the holders of at least 51% the then
outstanding shares of Series D Preferred Stock:

of the Preferred Stock and the conversion of principal and accrued interest on
the Convertible Subordinated Note issued by the Corporation to Genesis Holdings,
Inc., and dated January 31, 1997), any additional shares of Common Stock or
Preferred Stock;

                  (iv)     increase the number of authorized directors of the
Corporation's Board of Directors above twenty;

                  (v)      voluntarily liquidate,  dissolve or wind up the
Corporation or take any action that would result in the liquidation,
dissolution or winding up of the Corporation;

                  (vi) pay, declare or set aside any sums for the payment of,

substantially all of the business or assets of another Person for consideration
(including assumed liabilities) in excess of $750,000;

                  (ix) enter into or commit to enter any joint ventures or any

<PAGE>

                  (xiv)    adopt or approve the annual budget or business plan
of the Corporation.

                  2.       Dividends.

                  (a) When and as declared by the Board out of funds legally
available therefor, the Corporation shall pay dividends to the holders of the
Series D Preferred Stock as provided in this Subsection F.2.

                  (b) Cumulative dividends shall be payable on shares of the
Series D Preferred Stock at an annual rate of $.80 per share of Series D
Preferred Stock payable quarterly in arrears on the first day of every April,
July, October and January, commencing July 1, 1997 (each, a "Payment Date").
Each dividend will be payable to holders of record as they appear on the books
of the Corporation at the close of business on a record date (each a "Series D
Record Date"), not more than 60 nor less than 15 days before each Payment Date.
Dividends shall accrue from and including the Issue Date of the Series D
Preferred Stock and shall be cumulative (whether or not earned or declared).
Dividends payable for any period less than a full dividend period shall be
computed on the basis of a 360-day year consisting of twelve 30-day months. All
dividends shall be payable, at the option of the Corporation, either in
additional shares of Series D Preferred Stock (each, a "Series D Stock
Dividend") as provided in Subsection F.2(c) below or in cash out of funds
legally available therefor. If any Payment Date shall not be a Business Day,
payment shall be made on the next succeeding Business Day. In addition, if, in
any year, any cash or other distributions are declared by the Board to be paid
on Common Stock, or any class or subclass thereof, then an additional dividend
shall be paid at the same time to the holders of Series D Preferred Stock at the
rate per share equal to the product of (i) such per share dividend to be paid on
the Common Stock multiplied by (ii) the number of shares of Common Stock into
which each share of Series D Preferred Stock is then convertible

                  (c) Series D Stock Dividends shall be payable as follows: in
the event that any dividend shall be payable on Series D Preferred Stock in
additional shares of Series D Preferred Stock pursuant to Subsection F.2(b)
above, each holder of shares of Series D Preferred Stock as of the applicable
Series D Record Date shall be entitled to receive .08 shares of Series D
Preferred Stock per annum for each share of Series D Preferred Stock then held.

                  (d) All dividends paid hereunder shall be distributed by first
class mail to each holder as of the applicable Series D Record Date of Series D
Preferred Stock at the address of such holder specified in the records of the
Corporation.

                  (e) No full dividends may be declared or paid, and no funds
may be set apart for the payment of dividends, on any Series D Junior Securities
(other than dividends on Series D Junior Securities paid in additional shares of
Series D Junior

                                       39

<PAGE>

Securities of the same series or class to the extent required by these Articles)
unless full cumulative dividends to be paid hereunder prior to the date thereof
shall have been paid, and, to the extent payable in cash, paid or set aside for
payment, on the Series D Preferred Stock. No securities of the Corporation other
than Series D Preferred Stock may be repurchased, redeemed or otherwise acquired
nor may funds be set aside for payment with respect thereto, nor shall the
Corporation permit any corporation or entity directly or indirectly controlled
by the Corporation to purchase any securities of the Corporation other than
Series D Preferred Stock, if full cumulative dividends to be paid hereunder
prior to the date thereof have not been paid on the Series D Preferred Stock.

                  (f) The recipients of any Series D Stock Dividends shall have
the right at any time after the payment thereof, to require the Corporation to
redeem up to 50% of the shares of Series D Preferred Stock received in
connection with such Series D Stock Dividends at a price per share equal to
$10.00 per share of Series D Preferred Stock plus an amount equal to all
accumulated and unpaid dividends thereon. The recipients of any Series D Stock
Dividends shall only exercise their rights to require the Company to redeem
Stock Dividends to the extent such recipient determines in its reasonable good
faith judgment that such redemption is necessary for the Series D Preferred
Stockholders or their investors to pay taxes with respect to such Stock
Dividends. Redemptions made pursuant to this Subsection F.2(f) shall be
consummated not later than 20 calendar days after delivery of a redemption
notice from the holder requiring such redemption, and on such redemption date
the Corporation shall wire transfer to each holder the redemption price for the
shares of Series D Preferred Stock so redeemed.

                  3.       Redemption.

                  (a)      Redemptions  Initiated  by the  Corporation.  The
Corporation  may not require the  redemption  of any shares of Series D
Preferred Stock.

                  (b)      Redemptions Initiated by Holders of Series D
Preferred Stock.

                  (i) The holder or holders of at least 66-2/3% of the
outstanding shares of Series D Preferred Stock may, at their option, at any
time, or from time to time, from and after the fifth anniversary of the Issue
Date of the Series D Preferred Stock, require the Corporation to redeem, out of
funds legally available therefor, all of the outstanding shares of Series D
Preferred Stock (including shares not held by such holder or holders). The
redemption price payable upon any redemption pursuant to this Subsection
F.3(b)(i) shall be the greater of (x) an amount per share equal to $10.00 per
share of Series D Preferred Stock plus accrued but unpaid dividends thereon and
(y) the Fair Market Value of the shares of Series D Preferred Stock redeemed
pursuant to this Subsection F.3(b)(i). The date of any redemption required to be
made pursuant to this Subsection F.3(b)(i) shall be 20 calendar days after
delivery of the redemption notice, and on such redemption date the Corporation
shall

                                       40

<PAGE>

wire transfer to each holder the redemption price for the shares of Series D
Preferred Stock so redeemed.

                  (ii) Prior to a Qualified IPO, (i)if any action or
recommendation taken by the Executive Committee (as defined in ARTICLE V) is
overruled, rescinded, amended or otherwise contravened, avoided or negated by
the Board or (ii) the Board elects not to conduct the management of the Company
in accordance with Article V.2 of these Articles (including the creation and
empowerment of the Executive Committee), the holders of at least 66-2/3% of the
outstanding shares of Series D Preferred Stock may, at their option, at any time
within 60 days after such action by the Board, by written notice (a "Special
Redemption Notice") to the Corporation require the Corporation to redeem, out of
funds legally available, all of the shares of Series D Preferred Stock held by
such holders; provided, however, that if, within ten Business Days following
receipt of a Special Redemption Notice, the Board rescinds, amends, avoids or
negates its prior decision to overrule, rescind, amend or otherwise contravene,
avoid or negate an action or recommendation taken by the Executive Committee,
the circumstances giving rise to such Special Redemption Notice shall be deemed
to have been withdrawn and shall have no further effect and the Corporation
shall have no further obligation to redeem any shares of Series D Preferred
Stock pursuant to such Special Redemption Notice. The redemption price payable
upon any redemption pursuant to this clause (ii) shall be the greater of (x) an
amount per share equal to $10.00 per share of Series D Preferred Stock plus an
amount equal to cumulative dividends calculated at a rate of 15% per annum
accruing from the Issue Date of the Series D Preferred Stock, and (y) the Fair
Market Value of the shares of Series D Preferred Stock redeemed pursuant to this
clause (ii). The Corporation shall use its best efforts to consummate any
redemption being made pursuant to this clause (ii) as soon as possible but in
any event not later than six months after the date of a Special Redemption
Notice. The Corporation shall pay the redemption price with respect to the
shares of Series D Preferred Stock redeemed pursuant to this clause (ii) by bank
wire transfer to the holders of such shares.

                  (c) Redemption of Series D Junior Securities. Notwithstanding
any other provision of these Articles to the contrary and except for Sections
IV.C(3)(b)(i) and (ii) and IV.D(3)(b)(i) and (ii) and unless and until all of
the issued and outstanding Series D Preferred Stock has been either redeemed or
converted in accordance with this Section F, the Corporation may not and shall
not redeem, repurchase or otherwise make any payment in connection with the
acquisition, redemption, repurchase or cancellation of any Series D Junior
Securities or any stock options or similar rights with respect to any Series D
Junior Securities, and the Corporation shall cause all corporations,
partnerships, limited liability companies and other entities controlled,
directly or indirectly, by the Corporation to refrain from engaging in such
transactions.

                  4.       Conversion.

                  (a) In General. Upon the consummation of a Qualified IPO, each
share of Series D Preferred Stock shall automatically be converted into shares
of

                                       41

<PAGE>

Class C Common Stock at the then effective Series D Conversion Ratio. In
addition, at the option of the holder of any Series D Preferred Stock, such
holder shall have the right, at any time and from time to time prior to the
consummation of a Qualified IPO, by written notice to the Corporation, to
convert any and all shares of Series D Preferred Stock owned by such holder into
shares of Class C Common Stock at the then effective Series D Conversion Ratio.

                  (b)      Adjustments  to the Series D Conversion  Ratio.  The
Series D Conversion  Ratio shall be subject to adjustment  from time to time as
follows:

                  (i) In case the Corporation shall at any time or from time to
time after the Issue Date of the Series D Preferred Stock (A) pay a dividend, or
make a distribution, on the outstanding shares of Common Stock in shares of
Common Stock, (B) subdivide the outstanding shares of Common Stock, (C) combine
the outstanding shares of Common Stock into a smaller number of shares or (D)
issue by reclassification of the shares of Common Stock any shares of capital
stock of the Corporation, then, and in each such case, the Series D Conversion
Ratio in effect immediately prior to such event or the record date therefor,
whichever is earlier, shall be adjusted so that the holder of any shares of
Series D Preferred Stock thereafter surrendered for conversion shall be entitled
to receive the number of shares of Common Stock or other securities of the
Corporation that such holder would have owned or have been entitled to receive
after the happening of any of the events described above, had such shares of
Series D Preferred Stock been surrendered for conversion immediately prior to
the happening of such event or the record date therefor, whichever is earlier.
An adjustment made pursuant to this clause (i) shall become effective (x) in the
case of any such dividend or distribution, immediately after the close of
business on the record date for the determination of holders of shares of Common
Stock entitled to receive such dividend or distribution, or (y) in the case of
such subdivision, reclassification or combination, at the close of business on
the day upon which such corporate action becomes effective. No adjustment shall
be made pursuant to this clause (i) in connection with any transaction to which
Subsection B.5(k) applies.

                  (ii) Except with respect to Excluded Securities, in case the
Corporation shall issue shares of Common Stock or Common Stock Equivalents after
the Issue Date of the Series D Preferred Stock at a price per share (or having a
conversion, exercise or exchange price per share) less than the Series D Issue
Price per share of Common Stock as of the date of issuance of such shares or of
such convertible securities (the amount of such difference being referred to as
the "Series D Spread"), then, and in each such case, the Series D Conversion
Ratio shall be adjusted so that the holder of each share of Series D Preferred
Stock shall be entitled to receive, upon the Conversion thereof, the number of
shares of Common Stock determined by multiplying (A) the Series D Conversion
Ratio in effect on the day immediately prior to such date by (B) one plus a
fraction, the numerator of which shall be the amount of the Series D Spread and
the denominator of which shall be the Series D Issue Price (as defined below).
An adjustment made pursuant to this clause (ii) shall be made on the next
Business Day following the date on which any such

                                       42

<PAGE>

issuance is made and shall be effective retroactively to the close of business
on the date of such issuance. Upon the expiration of any unexercised Common
Stock Equivalents for which an adjustment has been made pursuant to this clause
(ii), the adjustment (and any subsequent adjustments) shall forthwith be
reversed to effect such rate of conversion as would have been in effect at the
time of such expiration or termination had such Common Stock Equivalents, to the
extent outstanding immediately prior to such expiration or termination, never
been issued. No adjustment shall be made pursuant to this clause (ii) in
connection with any transaction to which Subsection B.5(k) applies.

                  (iii) In case the Corporation shall at any time, or from time
to time, after the Series D Issue Date declare, order, pay or make a dividend or
other distribution (including, without limitation, any distribution of stock or
other securities or property or rights or warrants to subscribe for securities
of the Corporation or any of its Subsidiaries by way of dividend or spinoff), on
Common Stock, other than dividends or distributions on Common Stock that are
referred to in clause (i) of this Subsection F.4(b), then, and in each such
case, the Series D Conversion Ratio shall be adjusted so that the holder of each
share of Series D Preferred Stock shall be entitled to receive, upon the
conversion thereof, the number of shares of Common Stock determined by
multiplying (A) the applicable Series D Conversion Ratio on the day immediately
prior to the record date fixed for the determination of stockholders entitled to
receive such dividend or distribution by (B) a fraction, the numerator of which
shall be the Current Market Price per share of Common Stock as of such date, and
the denominator of which shall be such Current Market Price per share of Common
Stock less the Fair Market Value per share of Common Stock of such dividend or
distribution. No adjustment shall be made pursuant to this clause (iii) in
connection with any transaction to which Subsection B.5(k) applies.

                  (iv) The Series D Conversion Ratio shall be adjusted up or
down based on the ability of the Corporation to achieve certain performance
benchmarks with respect to the Corporation's Medicare Enrollees and Medical Loss
Ratio (each as defined in the letter from the Corporation to the holder of the
Series D Preferred Stock dated as of July 15, 1997). Adjustments to the Series D
Conversion Ratio shall be made pursuant to this clause (iv) on or before the
date the Corporation files its Annual Report on Form 10-K for the fiscal year
ended June 30, 1998, and the Corporation shall provide immediate written notice
thereof to the holders of Series D Preferred Stock.

                  (v) In case the Corporation shall consummate an IPO of its
Common Stock prior to June 30, 1998 at a price per share (prior to deducting
underwriting discounts and commissions and offering expenses) less than $13.00
(such price being referred to herein as the "IPO Price"), the Series D
Conversion Ratio shall be adjusted upward, but not downward, simultaneously with
the consummation of such IPO to the effect that immediately after such
adjustment each share of Series D Preferred Stock would be convertible into the
number of shares of Common Stock (including fractional shares) equal to the
number of shares of Common Stock into which each share of

                                       43

<PAGE>

Series D Preferred Stock would be convertible immediately prior to such
adjustment multiplied by a fraction, the numerator of which shall be $13.00 and
the denominator of which shall be the IPO Price.

                  (c) As used in this Subsection F.4, the term "Series D
Conversion Ratio" means the Conversion Ratio applicable with respect to Series D
Preferred Stock. The Series D Conversion Ratio shall initially equal one and
shall be subject to adjustment as provided in Subsection F.4(b). As used in this
Subsection F.4, the term "Series D Issue Price" means $10.00 per share (subject
to adjustment for stock dividends, stock splits, reclassifications and other
transactions that require an adjustment pursuant to Paragraph (b) of Subsection
F.4).

                  (d) If any event occurs as to which, in the opinion of the
Executive Committee (including the Series D Preferred Directors), the provisions
of this Subsection F.4 are not strictly applicable or, if strictly applicable,
would not fairly accomplish the intent of these provisions, the Executive
Committee (including the Series D Preferred Directors) shall make an adjustment
in the application of such provisions, in accordance with such intent, so as to
accomplish such intent.

                  5.       Liquidation Rights.

                  (a) Upon the dissolution, liquidation or winding up of the
Corporation (whether voluntary or involuntary) the holders of Series D Preferred
Stock shall be entitled to receive out of the assets of the Corporation
available for distribution to stockholders, before any payment or distribution
shall be made on any Series D Junior Securities, an amount equal to the greater
of (i) the Fair Market Value per share of Series D Preferred Stock plus accrued
but unpaid dividends thereon and (ii) $10.00 per share of Series D Preferred
Stock plus an amount equal to accrued but unpaid dividends on such shares of
Series D Preferred Stock and, thereafter, shall be entitled to share in amounts,
if any, distributed to holders of Common Stock upon liquidation as though the
Series D Preferred Stock had been converted to Common Stock immediately prior to
liquidation.

                  (b) After the payment to the holders of the Series D Preferred
Stock of the full preferential amounts provided for in this Subsection F.5, the
holders of Series D Preferred Stock as such shall have no right or claim to any
of the remaining assets of the Corporation.

                                    ARTICLE V

                  2. EXECUTIVE COMMITTEE. Except with respect to matters
requiring approval by the entire Board and which may not be delegated to a
committee of the Board under the MGCL ("Reserved Matters"), the authority of the
Board to act on all matters shall be vested in and exercised by an executive

                  3. WEIGHTED VOTING. If for either two consecutive fiscal
quarters or three fiscal quarters out of five consecutive fiscal quarters the
Corporation (a) fails to record positive net income as reflected on the
Corporation's financial statements prepared by the Corporation's "Big Six"
accounting firm and (b) has a Medicare Medical Loss Ratio with respect to the
Corporation's Medicare Enrollees of at least 90%, then each Series D Preferred
Director shall thereafter have ten votes with respect to all matters requiring
Board or Executive Committee approval or action. Any such determination shall be
made in accordance with the provisions of the Medicare Medical Loss Ratio Letter
dated July 15, 1997, and the weighted voting provisions of this Section shall be
effective at the time the Corporation files its quarterly report on Form 10-Q
(or its annual report on Form 10-K if the Loss Quarter is the last quarter of
the Corporation's fiscal year) with the Securities and Exchange Commission for
the applicable quarter. The Secretary of the Corporation shall provide written
notice to each director of the Corporation of the occurrence of circumstances
giving effect to the provisions of this Section 3 as promptly as practicable
following final determination thereof.

                  4. CONFLICT OF INTEREST. No contract or other transaction
between the Corporation and any other corporation, partnership, individual or
other entity and no act of the Corporation shall in any way be affected or
invalidated by the fact that any of the directors of the Corporation are
directors, principals, partners or officers of such other entity, or are
peculiarly or otherwise interested in such contract, transaction or act;
provided that (i) the existence of such relationship or such interest shall be
disclosed to the Board or to a committee of the Board if the matter involves a
committee decision, and the contract, transaction or act shall be authorized,
approved or ratified by a majority of disinterested directors on the Board or on
such committee, as the case may be, even if the number of disinterested
directors constitutes less than a quorum, or (ii) the contract, transaction or
act shall be authorized, ratified or approved in any other manner provided by
the MGCL.

                  5. BOARD  AUTHORIZATION  OF STOCK ISSUANCE.  Subject to such
rights and  restrictions  as may be granted to, and benefit,  the Class A Common
Stock, Class B Common Stock, Class C Common Stock, the Series A Preferred Stock,
the Series B Preferred Stock, the Series C Preferred Stock and the Series D
Preferred Stock hereunder, the Board is hereby empowered to authorize the

Class B Common Stock, the Class C Common Stock, the Series A Preferred Stock,
the Series B Preferred Stock, the Series C Preferred Stock and the Series D

unissued stock (including but not limited to authorized but unissued shares of
Preferred Stock), whether now or hereafter authorized, by setting or changing
the preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends, qualifications or terms or conditions of redemption
of such stock. Upon any such classification or reclassification, the Board shall
cause the Corporation to file articles supplementary with the Maryland State
Department of Assessments and Taxation, containing such provisions, if any, as
may at such time be required by the MGCL.


                  7. CONFLICT OF INTEREST. No contract or other transaction
between the Corporation and any other corporation, partnership, individual or
other entity and no act of the Corporation shall in any way be affected or

pecuniarily or otherwise interested in such contract, transaction or act;
provided that (i) the existence of such relationship or such interest shall be
disclosed to the Board or to a committee of the Board if the matter involves a
committee decision, and the contract, transaction or act shall be authorized,
approved or ratified by a majority of disinterested directors on the Board or on
such committee, as the case may be, even if the number of disinterested
directors constitutes less than a quorum, or (ii) the contract, transaction or
act shall be authorized, ratified or approved in any other manner provided by
the MGCL.

Accordingly, the provisions of Title 3, Subtitle 6 (Business Combination) and

enterprise as may be determined by the Board.

                  3. ADVANCING EXPENSES PRIOR TO A DECISION. The Corporation

the time a person serves as a director or officer of the Corporation whether or
not such person is a director or officer at the time of any proceeding in which
liability is asserted.

Ladies and Gentlemen:

         Reference  is made to Article IV,  Section  F.4(b)(iv)  of the Restated
Articles of Incorporation of Doctors Health, Inc. (the "Restated Articles"). The
adjustment to the conversion  ratio of the Series D Convertible  Preferred Stock
(the "Series D Preferred") of Doctors Health,  Inc. (the "Company")  referred to
in such Article  shall be made based on the matrix  attached as Exhibit A hereto
at the time referred to in such Article. This letter sets forth our agreement as
to the manner in which such matrix shall be applied.


         Reference is also made to Article V, Section 3 of the Restated Articles
of the Company. The terms "Medicare Medical Loss Ratio" and "Medicare Enrollees"
set forth in this letter agreement shall apply to Article IV, Section F.4(b)(iv)
and Article V, Section 3 of the Restated Articles.

         It is  acknowledged  and agreed that the  provisions of this letter are
for the benefit of all  holders of the Series D  Preferred,  including,  but not
limited to, The Beacon Group III - Focus Value Fund, L.P. ("Beacon").

         1. The term "Medicare Enrollees" means those persons enrolled under one
of the Company's Medicare global risk service agreements with health maintenance
organizations or other payors ("HMOs").

         2. The term  "Medicare  Medical Loss Ratio" means,  with respect to any
quarter or fiscal year (a "Period"), the number obtained by dividing:

                  (A) the sum of (i) all  direct  medical  expenses  paid by the
Company during the Period on behalf of Medicare Enrollees plus (ii) all payments
for specific stop-loss  insurance (net of recoveries)  applicable to such Period
plus (iii) all reserves



<PAGE>

as of the end of such Period, including those related to incurred but not
recognized  medical services  ("Medical  Management  IBNR") any additional
reserves established by the Company's  management,  calculated as set forth
herein ("IBNR") for services covered by the payments referred to in clause (i)
less (iv) IBNR reserves at the beginning of the Period; by

                  (B) all Medicare capitation revenues recognized by the Company
from HMOs  during the Period  under  generally  accepted  accounting  principles
("GAAP").

         3. For purposes of  calculating  the Medical Loss Ratio,  IBNR shall be
computed at the  beginning  and end of all Periods on a consistent  basis and in
the manner  described in the  Company's  "Medical Loss  Ratio/IBNR  Methodology"
attached  as Exhibit B hereto.  Assumptions  or  estimates  used at the end of a
Period  shall be  consistent  with  those  used at the  beginning  of the Period
(except  for changes  required  due to changes in actual  experience  during the
Period or forseeable  changes in the Company's  contracts or fee  arrangements).
Reversals of excess  reserves at the beginning of a Period will only be included
in the Medical Loss Ratio  calculation  pursuant to this letter agreement to the
extent that the reserve that remains  after such a reversal is  consistent  with
the  Company's  methodology  for  maintaining  such  reserves  at the end of the
period, but in no event will such a reserve be less than an amount equal to 110%
of the Company's  Medical  Management IBNR. The Company shall provide the holder
of the Series D Preferred  Stock a certificate of the Company's  Chief Financial
Officer (the "Excess  Reserve  Certificate")  setting from the percentage of the
Company's  IBNR  consisting  of excess  reserves.  The Company shall deliver the
Excess Reserve Certificate as soon as practicable after the date of this letter,
and in any event no later than the date the Company  issues its annual report on
Form 10-K for the fiscal year ended June 30, 1997.

         4.       (a) For  purposes  of the  adjustment  referred  to in
Article  IV, Section  F.4(b)(iv) of the Restated  Articles,  as promptly as
practicable after the end of the  Company's  fiscal year ended June 30, 1998,
and in any event no later than the date the  Company  files its  annual  report
on Form 10-K for the fiscal  year  ended  June  30,  1998  with  the  U.S.
Securities  and  Exchange Commission, the Company shall provide to each holder
of the Series D Preferred a certificate of the Company's  Chief  Financial
Officer (the "CFO  Certificate") setting  forth (i) the  Company's  Medical
Loss Ratio for the fiscal year ended June  30,  1998  and the  methodology,  in
reasonable  detail,  used  for  such calculation and (ii) the number of Medicare
Enrollees at June 30, 1998.

                  (b) For purposes of the  provisions of Article V, Section 3 of
the Restated  Articles,  as promptly as practicable after the end of any Company
fiscal  quarter  for which the  Company  failed to have  positive  net income as
reflected on the Company's financial statements for such quarter provided by the
Company to Beacon pursuant to the terms of the Shareholders'  Agreement (a "Loss
Quarter"), within 45 days after the end of the Loss Quarter but in any event not
later than the date the Company files its quarterly report on Form 10-Q with the
U.S. Securities and

<PAGE>



Exchange Commission (or Form 10-K if the Loss Quarter is the last quarter of the
Company's  fiscal  year),  the Company shall provide to each holder of the
Series D  Preferred  Stock a CFO  Certificate  setting  forth the Company's
Medical Loss Ratio for the Loss Quarter.  The  Company's  independent auditors,
which shall be a "Big Six" accounting firm (the "Company's Auditors"), shall
perform  certain review  procedures with respect to the Medical Loss Ratio
reported  by the  Company  for any such Loss  Quarter  contemporaneous  with the
issuance  of the  Company's  Form 10-Q ( or 10-K as  applicable)  and advise the
Company of such  accounting  firm's  review  procedures  and report  whether the
Company complied with the provisions of Exhibit B attached hereto.

         5. In the event the Company has two consecutive  Loss Quarters or three
Loss  Quarters  out of five  consecutive  quarters,  the Company  shall,  at the
Company's  expenses,  engage the Company's Auditors to audit and issue its audit
with respect to the Company's  financial  statements and the CFO Certificate for
each of the Loss Quarters.  Such audit shall be commenced as soon as practicable
following the last day of the second consecutive Loss Quarter or the last day of
the third Loss Quarter out of five consecutive quarters.

         6. In the event that (i) the Company has two consecutive  Loss Quarters
or three Loss Quarters out of five consecutive quarters and (ii) the Company has
received  an audit by the  Company's  Auditors  or, for  purposes of Article IV,
Section  F.4(b)(iv) of the Restated  Articles,  the Company has filed its annual
report on Form  10-K,  Beacon  shall be  entitled  to have  each such  financial
statement  and  CFO  Certificate  audited  by its  various  advisors  using  any
methodologies  it deems  appropriate and Beacon agrees that it will use its best
efforts to ensure that such audit is completed within 45 days following delivery
of such  statement to it. If Beacon's  audit of such  statement and the data set
forth therein  cannot be reconciled by agreement  between Beacon and the Company
within 10 days following the end of such 45-day period, each of us hereby agrees
to submit the matter to an independent  arbitrator,  who shall be a partner in a
"Big Six" accounting firm other than the Company's Auditors who has professional
expertise  with  such  matters  and  who  is  acceptable  to  both  of  us  (the
"Arbitrator").  If the  parties  are  unable  to agree on the  identity  of such
arbitrator  within five days after the end of the 10-day  period,  either  party
shall  have  the  right  to  ask  the  President  of  the  American  Arbitration
Association  to select the  Arbitrator.  The  Arbitrator  shall  examine (i) the
statement and CFO  Certificate  prepared by us and the supporting  documentation
provided  therewith  and (ii) the  results  of the audit  prepared  by  Beacon's
advisors and the supporting analyses provided therewith.  Not later than 30 days
following  submission of such matters to the  Arbitrator,  the Arbitrator  shall
deliver to each of us his written  report  setting  forth his  determination  of
Medical  Loss Ratio and  Medicare  Enrollees  for the period and the  supporting
calculations therefore. Such report shall be final and binding and shall be used
for  the  purposes  of  calculating  the  adjustments  to the  conversion  ratio
applicable  to the  Series D  Preferred  as  provided  in  Article  IV,  Section
F.4(b)(iv) of the Restated  Articles  and/or to effect the provisions of Article
V, Section 3 of the Restated Articles,  as applicable.  The fees and expenses of
any Arbitrator shall be born by the Company.

                      Medical Loss Ratio/IBNR Methodology

                  The  Company is  required  by  Generally  Accepted  Accounting
Principles  (GAAP) to estimate a reserve for incurred but not reported  services
(IBNR) in order to match the incurred  expenses with the revenues  recognized in
its financial statements.  Various method(s) are used by HMO's and other managed
care  providers to calculate the IBNR in accordance  with GAAP.  The Company has
determined  that  given its  limited  amount of  historical  experience  and its
tightly  managed  population,  that  pricing  all  authorized  services  per the
MedAdvice Medical Management System (MedAdvice) will be its primary  methodology
to determine IBNR in accordance with GAAP.

                  The methodology derives all authorized units of service (days,
specialist visits, home health visits, etc.) from MedAdvice and prices the units
of service at the expected  cost.  The prices for the units of service are based
on the best estimate of the health care price per unit  (contracted fee schedule
amounts, contracted per diem rates, average historical cost, etc.). In addition,
estimates  are made for large  cases  (up to the  stop-loss  attachment  point),
emergency  services  which  were  not  authorized  until  after  the  event  and
authorized  services not yet  incurred.  From time to time and as changes in the
Company's patient pools,  medical expense experience and contracts may indicate,
the  Company  may  increase or  decrease  the  reserve  created  pursuant to the
foregoing  MedAdvice  cost  estimating  methodology.  The Company  will  perform
periodic  "lookback"  tests to validate the methodology and assumptions and make
revisions, as necessary.

                  The Company reserves the right to take guidance from any other
methodology that complies with generally accepted accounting  principles and the
Company's  reporting  requirements  established  by the  Securities and Exchange
Commission.



                                                                     Exhibit 3.3

                                    AGREEMENT

This Agreement is entered into this 15th day of July, 1997, in connection with
the purchase by The Beacon Group III - Focus Value Fund, L.P. ("Beacon") of
3,000,000 shares of Doctors Health, Inc. (the "Company") Series D Preferred
Stock (the "Series D Preferred Stock") and related amendments and modifications
to existing rights and obligations of the Company's shareholders and managers
(the "Transaction").

The current documents relating to the Transaction (the "Transaction Documents")
incorporate a certain "MLR Side Letter" that adjusts the "Conversion Price" of
the Series D Preferred Stock at the end of FY 1998, if and to the extent the
Company achieves, or fails to achieve, certain benchmarks.

It has come to the attention of Beacon that:

         1) the Finance Committee of the United States Senate completed its
Medicare budget proposals during the week of June 16, 1997 , and the House
Commerce Committee of the United States House of Representatives passed its
version of Medicare budget proposals on June 11, 1997,

         2) Congress intends to have a final bill for the President's  signature
by August 1, 1997, and

         3) the Senate version contains changes to the Medicare's managed care
payment methodology that would reduce payments for new Medicare HMO enrollees by
5% below the current 95% of historic reimbursement level in the enrollee's first
year of enrollment, and then adjust the reimbursement for each of the 4 years
thereafter (the "Proposed Senate Risk Adjustment").

Beacon and the Company believe that while passage as law of the Proposed Senate
Risk Adjustment provisions, or substantially similar provisions that reduce
payments to Medicare HMOs for enrollees below the current 95% of historic
reimbursement level, is not likely, the risk that the Proposed Senate Risk
Adjustment, or substantially similar provisions, is a risk fairly borne by the
Company and not by Beacon.

The Company and Beacon therefore wish amend, and hereby amend, the Transaction
Documents to provide that if the Proposed Senate Risk Adjustment provisions (or
substantially similar provisions that reduce payments to Medicare HMOs for
enrollees below the current 95% of historic reimbursement) are passed as law
during the 105th Congress of the United States and such reduced payments become
effective during FY 1998, and are applicable to the Company's reimbursement,
then Exhibit A to the MLR Letter will be replaced by the "Revised Exhibit A"
attached as Exhibit A.


<PAGE>

The foregoing obligations of the Company to replace Exhibit A of the MLR Letter
with the Revised MLR Letter are subject to ratification and adoption by the
Company's Executive Committee and/or Board of Directors as soon as practicable
after closing, but in no event later than July 31, 1997. To this end, each of
Stewart Gold, Paul Serini and John Dwyer agree to use his best efforts to cause
the Executive Committee of Board to ratify and approve the Revised MLR Letter,
and hereby unconditionally, jointly and severally, agree to hold Beacon harmless
from and against any loss, costs (including reasonable attorneys fees) or
damages incurred by Beacon as a result of the Executive and/or the Board failing
to so ratify and adopt.

such other form as may be permitted by the Maryland General Corporation Law,

unless the Secretary of the Corporation is notified in writing by any co-owner
or co-fiduciary that the joinder of more than one is to be required. At all

                  Each stockholder shall be entitled to a certificate or
certificates which shall represent and certify the number and class of shares of
stock owned in the Corporation. Each certificate shall be signed by the
President and Chief Executive Officer or any Vice President and be countersigned
by the Secretary or any Assistant Secretary or the Treasurer or any Assistant
Treasurer. The signatures of the Corporation's officers and its corporate seal
appearing on stock certificates may be facsimiles if each such certificate is
authenticated by the manual signature of an officer of a duly authorized
transfer agent. Stock certificates shall be in such form, not inconsistent with
law and the Charter, as shall be approved by the Board of Directors. In case any
officer of the Corporation who has signed any certificate ceases to be an
officer of the Corporation, whether by reason of death, resignation or
otherwise, before such certificate is issued, then the certificate may
nevertheless be issued by the Corporation with the same effect as if the officer
had not ceased to be such officer as of the date of such issuance.

Section 2.  Transfers.

                  The Board of Directors shall have power and authority to make
all such rules and regulations as the Board may deem expedient concerning the
issue, transfer and registration of stock certificates. The Board of Directors
may appoint one or more transfer agents and/or registrars for its outstanding
stock, and their duties may be combined. No transfer of stock shall be
recognized or binding upon the Corporation until recorded on the books of the
Corporation, or, as the case may be, of its transfer agent and/or of its
registrar, upon surrender and cancellation of a certificate or certificates for
a like number of shares.

Section 3.  Record Dates for Dividends and Stockholders'
Meeting.

                  The Board of Directors may fix a date not exceeding 90 days
preceding the date of any meeting of stockholders, any dividend payment date or
any date for the allotment of rights, as a record date for the determination of
the stockholders entitled to notice of and to vote at such meeting, or entitled
to receive such dividends or rights, as the case may be, and only stockholders
of record on such date shall be entitled to notice of and to vote at such
meeting or to receive such dividends or rights, as the case may be. In the case
of a meeting of stockholders, the record date shall be fixed not less than ten
days prior to the date of the meeting.

Section 4.  New Certificates.

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

nature of the  activities  conducted by it makes such  qualification  necessary,
except for those  jurisdictions where the failure to be so qualified and in good
standing  would not,  individually  or in the  aggregate,  have or reasonably be
expected  to  have  a  material  adverse  effect  on the  business,  operations,
properties,  assets,  condition (financial or other) or results of operations of
the Company and its subsidiaries taken as a whole (a "Material Adverse Effect").

      2.2.  Authorization  of  the  Documents.   The  execution,   delivery  and

enforceability  may be limited by

SECTION 7. Termination.

      7.1.  Termination.  The obligations of the parties hereunder to effect the
Purchase may be terminated (i) by the mutual written  consent of the Company and
Beacon or (ii) by any  party in  writing,  without  liability  to such  party on
account of such termination  (provided the terminating party is not otherwise in
breach and/or default of this Agreement), if the Closing shall not have occurred
on or before July 31, 1997.

      7.2.  Effect of  Termination.  Termination  pursuant  to Section 7.1 shall
terminate  all  obligations  of the  parties  to  effect  the  Purchase  and all
obligations or liabilities relating thereto except for liabilities for breach by

SECTION 8. Indemnification.

      8.1. General Indemnification. The Company shall indemnify, defend and hold
Beacon, its affiliates, their respective officers, directors, partners, members,
shareholders, employees, agents, representatives,  successors and assigns (each,
a "Beacon  Entity")  harmless from and against all Losses (as defined in Section
8.2)  incurred  or  suffered by a Beacon  Entity  (whether  incurred or suffered
directly or indirectly  through  ownership of Common Stock or Preferred Stock or
any other securities of the Company) arising or resulting from the breach of any
of the representations,  warranties, covenants or agreements made by the Company
in this Agreement or in any certificate or other instrument  delivered  pursuant
hereto including,

                                      -31-

<PAGE>

without limitation, the Documents.  Beacon shall indemnify,  defend and hold the
Company,  its affiliates,  their respective officers,  directors,  shareholders,
employees, agents, representatives,  successors and assigns harmless against all
Losses  arising  from  the  breach  of any of its  representations,  warranties,
covenants  or  agreements  in this  Agreement  or in any  certificate  or  other
instrument  delivered  pursuant  hereto,  including,   without  limitation,  the
Documents.

      8.2. Indemnification  Principles. For purposes of this Section 8, "Losses"
shall mean each and all of the following  items:  claims,  losses,  liabilities,
obligations,  payments, damages, charges,  judgments, fines, penalties,  amounts
paid in settlement, costs and expenses (including, without limitation,  interest
that  may  be  imposed  in   connection   therewith,   costs  and   expenses  of
investigation,  actions,  suits,  proceedings,  demands,  assessments  and fees,
expenses and disbursements of counsel, consultants and other experts), provided,
that all  calculations  of Losses with respect to an indemnified  claim shall be
net  of any  insurance  proceeds  and  tax  benefits  actually  realized  by the
indemnified party with respect to such claim. Any indemnification payment by the
Company to Beacon pursuant to this Section 8 shall include an additional  amount
so that Beacon  suffers no Loss as a result of any  diminution in the book value
of the  shareholder's  equity related to its investment under the Agreement as a
result of such  indemnification  payment (it being  agreed that if a Loss occurs
after an initial public offering of the Company, any such diminution in the book
value of  Beacon's  shareholder's  equity  shall not be measured in terms of the
multiple to book value at which the Company's shares are traded). Any payment by
the Company to Beacon  pursuant to this  Section 8, shall be treated for federal
income tax purposes as an  adjustment to the price paid by Beacon for the Series
D Preferred  Stock pursuant to this Agreement,  except as otherwise  required by
law.  Notwithstanding  any other  provision  of this  Section 8, (i) the Company
shall  not be  required  to  provide  indemnification  for any  breaches  of the
Company's  representations or warranties unless the aggregate of all amounts for
which such  indemnification  is due exceeds $250,000,  in which case the Company
shall be liable for  indemnification  for all such amounts from first dollar and
(ii) in no event shall the Company be  required to provide  indemnification  for
breaches of its  representations and warranties for any individual claim of less
than $15,000.

      8.3. Claim Notice.  A party seeking  indemnification  under this Section 8
shall,  promptly upon becoming  aware of the facts  indicating  that a claim for
indemnification may be warranted, give to the party from whom indemnification is
being sought a claim notice relating to such Loss (a "Claim Notice"). Each Claim
Notice shall specify the nature of the claim,  the  applicable  provision(s)  of
this Agreement or other instrument  under which the claim for indemnity  arises,
and, if possible,  the amount or the  estimated  amount  thereof.  No failure or
delay in giving a Claim Notice (so long as the same is given prior to expiration
of the  representation or warranty upon which the claim is based) and no failure
to include any specific information relating to the claim (such as the amount or
estimated amount thereof) or any reference to any provision of this Agreement or
other instrument under which the claim arises shall affect the obligation of

                                      -32-

<PAGE>

the party  from whom  indemnity  is sought  except to the  extent  such party is
materially prejudiced by such failure or delay.

      8.4. Claim Procedure. (a) If any indemnified party hereunder determines to
seek indemnification  under this Section 8 with respect to Losses resulting from
the assertion of liability by third parties,  such indemnified  party shall give
notice to the  indemnifying  party hereunder  within 10 days of such indemnified
party  becoming  aware of any such  Losses or of facts  upon which any claim for
such Losses will be based; the notice shall set forth such material  information
with respect thereto as is then reasonably  available to such indemnified party.
In case any such liability is asserted against such indemnified  party, and such
indemnified  party notifies the  indemnifying  party thereof,  the  indemnifying
party will be  entitled,  if it so elects by written  notice  delivered  to such
indemnified  party  within 10 days  after  receiving  such  indemnified  party's
notice,  to  assume  the  defense  thereof  with  counsel  satisfactory  to such
indemnified  party, in which case, the indemnifying  party will not be liable to
the  indemnified  party under this Section 8.4. for any legal or other  expenses
subsequently  incurred by such indemnified  party in connection with the defense
thereof unless (i) the indemnified party shall have employed separate counsel in
accordance with the following  sentence or (ii) the indemnifying party shall not
have employed  counsel  satisfactory to the  indemnified  party to represent the
indemnified  party within a reasonable  time after notice of commencement of the
action,  in each of which cases the fees and expenses of counsel shall be at the
expense of the  indemnifying  party.  Notwithstanding  the  foregoing,  (A) such
indemnified  party  shall have the right to employ  its own  counsel in any such
case, but the fees and expenses of such counsel shall be at the expenses of such
indemnified party unless such indemnified party shall reasonably  determine that
there is a conflict of interest between or among such indemnified  party and the
indemnifying  party  with  respect  to such  claim,  in which  case the fees and
expenses  of such  counsel  will be borne by the  indemnifying  party,  (B) such
indemnified  party  shall  not have any  obligation  to give any  notice  of any
assertion of liability by a third party unless such assertion is in writing, (C)
the rights of such indemnified  party to be indemnified  hereunder in respect of
any  Losses  that may or do result  from the  assertion  of  liability  by third
parties shall not be adversely  affected by its failure to give notice  pursuant
to the foregoing  unless,  and, if so, only to the extent that, the indemnifying
party  is  materially  prejudiced  thereby,  and  (D) the  indemnifying  party's
obligations to such  indemnified  party under this Section 8 shall not terminate
until such  indemnified  party's  claims  have been  finally  satisfied  to such
indemnified party's sole satisfaction. In the event that the indemnifying party,
within 10 days after receipt of the aforesaid notice of a claim hereunder, fails
to assume  the  defense of such  indemnified  party  against  such  claim,  such
indemnified party shall have the right to undertake the defense,  compromise, or
settlement of such action on behalf of and for the account, expense, and risk of
the  indemnifying  party.  Notwithstanding  anything  in this  Section  8 to the
contrary,  if there is a  reasonable  probability  that a claim  may  materially
adversely affect such indemnified  party, (x) such indemnified  party shall have
the right to participate in such defense,  compromise, or settlement and (y) the
indemnifying  party shall not, without such indemnified  party's written consent
(which consent shall not be

                                      -33-

<PAGE>

unreasonably  withheld),  settle or compromise any of such claims, or consent to
entry of any judgment in respect thereof unless such settlement,  compromise, or
consent includes as an unconditional  term thereof the giving by the claimant or
the plaintiff to such indemnified  party a release from all liability in respect
of such claim.  With respect to any assertion of liability by a third party that
results in any claim for  indemnification  hereunder,  the parties  hereto shall
make  available  to each  other all  relevant  information  in their  possession
material to any such assertion.

      (b) In the event that an  indemnified  party  asserts the  existence  of a
claim with respect to Losses (but excluding  claims resulting from the assertion
of liability by third parties), it shall give written notice to the indemnifying
party.  Such written  notice shall state that it is being given pursuant to this
Section  8.4(b),  specify  the  nature  and  amount of the claim  asserted,  and
indicate  the date on which  such  assertion  shall be deemed  accepted  and the
amount  of the  claim  deemed a valid  claim  (such  date to be  established  in
accordance with the next sentence).  If the indemnifying  party,  within 30 days
after the mailing of notice by such  indemnified  party,  shall not give written
notice to such  indemnified  party  announcing  in its  intent to  contest  such
assertion of such indemnified party, such assertion shall be deemed accepted and
the amount of claim shall be deemed a valid claim. In the event,  however,  that
the indemnifying  party contests the assertion of a claim by giving such written
notice to such Indemnified party within said period,  then the parties shall act
in good  faith to reach  agreement  regarding  such  claim.  In the  event  that
litigation  shall arise with  respect to any such claim,  the  prevailing  party
shall be entitled to reimbursement of costs and expenses  incurred in connection
with such litigation  including attorney fees, if the parties hereto,  acting in
good faith,  cannot reach  agreement  with respect to such claim within ten days
after such notice.

      SECTION 9. Subsequent  Closing.  (a) Subject to Section 9(b), Beacon shall
purchase  from the Company,  and the Company shall sell to Beacon free and clear
of  all  Encumbrances,  1,000,000  shares  of  series  D  Preferred  Stock  (the
"Subsequent  Shares")  for an  aggregate  purchase  price  of  $10,000,000  (the
"Subsequent  Purchase  Price").  The  closing  of the  purchase  and sale of the
Subsequent  Shares (the "Subsequent  Closing") shall take place on June 30, 1998
(or such earlier date as the parties may agree),  provided  that the  conditions
set forth in Section  9(b) shall  have been  satisfied  or waived on or prior to
such date.  At the  Subsequent  Closing,  the Company  shall deliver to Beacon a
certificate or certificates representing the Subsequent Shares registered in the
name of Beacon or an affiliated nominee. Delivery of such certificates to Beacon
shall be made  against  receipt by the  Company  from  Beacon of the  Subsequent
Purchase Price, which shall be paid by wire transfer to an account designated at
least two business  days prior to the  Subsequent  Closing by the Company.  Upon
payment of the Subsequent  Purchase Price, the Subsequent  Shares shall be fully
paid and  non-assessable.  The parties acknowledge and agree that the conversion
ratio for the Subsequent Shares as of the Subsequent Closing shall be determined
by reference to the conversion  matrix set forth in the letter agreement between
the Company and Beacon dated as of the date hereof.

                                      -34-

Closing of each of the following conditions:

           (i) The Closing shall have occurred;

           (ii) The Company  shall have  complied in all material  respects with
all of its agreements and covenants contained in the Documents;

           (iii) No event or change shall have occurred that, individually or in
the aggregate,  has had, or may have, a material adverse effect on the business,
assets, liabilities,  properties, condition (financial or otherwise), prospects,
operations or results of operations of the Company;

           (iv)  All  actions  by  or  in  respect  of,  or  filings  with,  any
governmental  body,  agency,  official  or  authority  required  to  permit  the
consummation of the Subsequent  Closing shall have been taken,  made or obtained
(including the expiration or termination of any applicable waiting periods under
the HSR Act);

           (v) No  statute,  rule or  regulation  or order  of any  court or any
governmental  authority  shall  be in  effect,  and  no  proceedings  have  been
instituted to obtain such an order, that, in any case, restrains, enjoins, makes
illegal or otherwise  prohibits the transactions  contemplated by the Subsequent
Closing; and

           (vi) Beacon shall have received from the Company's counsel an opinion
addressed to Beacon,  dated as of the Subsequent  Closing,  satisfactory in form
and substance to Beacon.

      (c) If prior to June 30, 1998 the Company  notifies  Beacon in writing (i)
that all or a portion of an  acquisition  or capital  expenditure by the Company
requiring  equity  capital of the  Company in excess of  $750,000,  which is not
contemplated  by the Company's  operating plan as of the date hereof,  a copy of
which is attached  hereto as Exhibit H, has been approved by the Company's Board
of Directors and the Company will be unable to consummate  such  acquisition  or
capital  expenditure  (without  the  use of  cash  already  contemplated  in the
Operating Plan) unless the Subsequent Closing occurs, (ii) that the indebtedness
described on Schedule 9(c) hereto has become due and payable and the Company has
been unable to refinance such indebtedness and has no sources of funds available
to  it to  repay  such  indebtedness  at  maturity  (other  than  cash  or  cash
equivalents held by the Company for application pursuant to its Operating Plan),
or (iii) that the  Company  requires  additional  equity  capital to satisfy its
obligations  to  redeem  any  shares of Series D  Preferred  redeemed  by Beacon
pursuant to Article IV.F.2(f) of the Restated Articles, then Beacon shall permit
the Subsequent Closing to occur on the date requested by the Company (which date
may be prior  to June  30,  1998) to the  extent,  but only to the  extent,  the
Company  requires  proceeds of such  portion of the  Subsequent  Closing for the
purposes  described  in  clauses  (i),  (ii) or  (iii),  provided  that  (x) the
conditions set forth in Section 9(b) must still be satisfied or

                                      -35-

<PAGE>

waived  by  Beacon  prior to such  date and (y) the  Company  actually  uses the
proceeds  of  the  Subsequent   Closing  for  such  acquisition,   repayment  or
redemption.  Any  Subsequent  Shares not  purchased  by Beacon  pursuant to this
Section  9(c)  shall be  purchased  by  Beacon at the June 30,  1998  Subsequent
Closing, subject to the terms and conditions of Sections 9(a) and 9(b).

SECTION 10. Remedies. In case any one or more of the covenants and/or agreements
set forth in this  Agreement  shall  have  been  breached  by any party  hereto,

diligence  investigation  thereof,  including,  but not  limited  to,  fees  and
expenses  of  Beacon's  legal  counsel,  accountants  and  consultants  or  (ii)

expenses in the aggregate to not more than $350,000.

SECTION 12. Taxes.  The Company shall pay any  transfer,  documentary,  stamp or
other similar Taxes that may be determined to be payable in connection  with the

hereby  amended by  deleting  Section  2.3(c) and inserting in lieu thereof:


                           "(c)     The shares of Class C Common Stock issuable
upon conversion of the Series D Preferred Stock issued to Beacon on the date of

Series D Preferred Stock outstanding), in the aggregate,  28.7% of the
outstanding  Common Stock of the Company on the date  of the  Closing  on a
fully  diluted  basis  (assuming  for  purposes  of calculating full dilution,
all securities  convertible into, or exchangeable or exercisable   for,   shares
of  Common  Stock   (collectively,   "Common  Stock Equivalents") as having been
converted,  exchanged, or exercised) and the voting power of such issued shares
will represent, in the aggregate, 28.7% of the total number of votes able to be
cast on any matter by all  voting  securities  of the Company  (other  than any
matter the  holders of Class A Common  Stock,  Class B Common Stock,  Series A

entitled by law or pursuant to the Restated Articles to vote on as a separate
class and any matter to be voted on by the holders of shares of Series D

                  This AMENDED AND RESTATED STOCK PURCHASE AGREEMENT (the
"Agreement") is entered into this 9th day of July, 1997, as amended on July 15,
1997 by and among UniversityCare, L.L.C., a Maryland limited liability company,
("UniversityCare"), Doctors Health System, Inc., a Maryland corporation
("Doctors"), Genesis Health Ventures, Inc., a Delaware corporation ("Genesis")
and Med-Lantic Management Services, Inc., a Maryland corporation ("MMS").

                  WHEREAS, Doctors is a managed care and medical management
company which develops and consolidates individual and groups of primary care
physicians, specialist physicians, hospitals and other health care providers
into primary care-driven, comprehensive managed care health delivery networks;
and

                  WHEREAS, UniversityCare is a limited liability company formed
for the purpose of creating a joint venture between the University of Maryland
Medical System Corporation and University Physicians, Inc.

                  WHEREAS, Genesis and MMS have entered into an agreement, dated
May 2, 1997, for the purchase by Genesis from MMS of approximately 408,000
shares of Series B Preferred Stock (the "Series B Stock") held by and/or due in
exchange for interest payments due and payable by Doctors to MMS (or its wholly
owned subsidiary) (the "Purchase Agreement"); and

                  WHEREAS, UniversityCare wishes to assume, by novation, all of
Genesis's rights and obligations under the Purchase Agreement, and to purchase
the Series B Stock from MMS, subject to the additional terms and conditions
contained herein; and Doctors, MMS and Genesis agree herein to assign and
delegate to UniversityCare, by novation, all of Genesis's rights and obligations
under the Purchase Agreement; and, upon such assignment and assumption, and the
closing of the transactions contemplated by this Agreement, Genesis shall be
released from any and all obligations under the Purchase Agreement;

                  WHEREAS, Doctors, Genesis and MMS wish to facilitate the
purchase by UniversityCare on the terms and subject to the conditions set forth
in this Agreement.

                  NOW, THEREFORE, in consideration of the premises and subject
to the representations, warranties, covenants, and conditions contained herein,
the parties agree as follows:

             1.1  Purchase of the Shares. MMS and Genesis hereby agree to the
assignment and delegation of all of Genesis's rights and obligations under the
Purchase Agreement, by novation, to UniversityCare. Upon such assignment,
assumption and closing of the transactions contemplated by this Agreement,
Genesis shall be released from any and all obligations or liability under the
Purchase Agreement; provided, that in the event the Closing does not occur for
any reason, Genesis's obligation under the Purchase Agreement shall continue in

it of any court or of any federal, state, municipal, or other governmental
department, commission, board, bureau, agency, or instrumentality, domestic or
foreign. There is no action or suit by Doctors pending or threatened against
others. Upon receipt of written approval for the transactions contemplated
herein from the applicable state regulatory bodies, if any, Doctors will have
complied in all material respects with all laws, rules, regulations, and orders
applicable to its businesses, operations, properties, assets, products, and
services, and Doctors has all necessary permits, licenses, and other
authorizations required to conduct its businesses as conducted and as proposed
to be conducted. There is no existing law, rule, regulation, or order, or
proposed law, rule, regulation, or order, whether federal, state, local, or
professional, which would prohibit or

                                      -8-

<PAGE>

restrict Doctors from, or otherwise materially adversely affect Doctors in
conducting its business in any jurisdiction in which it is now conducting
business or in which it proposes to conduct business.

tax returns, including, without limitation, income, sales, single business,
payroll, premium, withholding, informational and personal property tax returns,
required to be filed by it and such returns have been duly prepared and filed
and were true, correct, and complete. All taxes due by reason of the operations
conducted by Doctors have been paid, including, without limitation, all taxes
which Doctors are obligated to withhold from accounts owing to employees,
creditors, and third parties. All such taxes for which any such party has become
obligated pursuant to elections made in accordance with generally accepted
accounting principles have been paid and adequate reserves have been established
for all taxes accrued but not yet payable. The federal income tax returns of
Doctors have never been audited by the Internal Revenue Service. No deficiency
assessment with respect to any proposed adjustment of Doctors's federal, state,
county or local taxes is pending or threatened. There is no tax lien, whether
imposed by any federal, state, county or local taxing authority outstanding
against the assets, properties or businesses of Doctors. There is no pending
examination or proceeding by any authority or agency relating to the assessment
or collection of any such taxes, interest or penalties thereon, nor do there
exist any facts that would provide a basis for any such assessment. Doctors has
not executed or filed any consent or agreement to extend the period for
assessment or collection of any such taxes.

             2.15  Employees.  Doctors  is not a party to any  collective
bargaining  agreement.  There is no labor strike or other  disturbance or any
union organizing  effort with respect to Doctors.  Doctors's  relationship with
its employees may be characterized as good.

             2.16  Insurance Coverage. Doctors has maintained, with financially
sound and reputable insurers, professional liability, casualty, property loss,
and other insurance coverage of such types and in such amounts as is customary
for companies similarly situated. Schedule 2.16 lists and briefly describes the
policies concerning such insurance coverage, and, except as otherwise provided
on Schedule 2.16, all such policies will continue in effect after the Closing
Date. Doctors has not received any notice of any default with respect to its
obligations under any of such insurance policies.

             2.17  Contracts and Other Commitments. Each material contract of
Doctors, including, but not limited to each agreement between Doctors and any
core medical group, individual practice association or other provider of health
care services, is a valid and binding obligation of the parties thereto,
enforceable in accordance with its terms (subject to bankruptcy, insolvency,
reorganization, moratorium and other laws affecting creditors' rights generally
and except for limitations upon the availability of equitable remedies,
including specific performance). Except as set forth on Schedule 2.17, none of
the transactions contemplated by this Agreement creates in any party to any
material contracts and commitments the right to revise the terms of, to
terminate, to accelerate any obligation of Doctors or otherwise declare that
such contracts or commitments have been breached. Doctors is not aware of any
defaults and do not

                                      -9-

<PAGE>

have any reason to believe that a default may occur by Doctors or any other
party to the contracts and commitments to which Doctors may become a party (by
assignment, transfer by operation of law, succession, or otherwise). For
purposes of this Section, the term "material" means having a value of $10,000 or
more, and shall include any and all provider and payor agreements, irrespective
of the dollar value.

             2.18  Fees and Commissions. Except as set forth on Schedule 2.18,

originator's fees or commissions by reason of services alleged to have been
rendered for, or at the instance of, Doctors in connection with this Agreement
and the transactions contemplated hereby.

             2.19  Disclosure. No representation or warranty by Doctors in this
Agreement, and no exhibit, schedule, or certificate furnished or to be furnished
by Doctors pursuant hereto, contains any untrue statement of a fact, or omits to
state a fact required to be stated herein or therein or necessary to make the
statements contained herein or therein not misleading. There is no fact of which
Doctors is aware, which has not been disclosed in writing to UniversityCare,
which adversely affects Doctors. Neither this Agreement, the business plan of
Doctors, the Financial Statements, nor any other agreement, document,
certificate or written statement furnished to UniversityCare or its counsel by
or on behalf of Doctors in connection with the transactions contemplated hereby
contains any untrue statement of material fact or omits to state a material fact
necessary in order to make the statements contained herein or therein not
misleading. Projections made in the Business Plan are not considered to be facts
for the purpose of this Section. There is no fact within the knowledge of
Doctors or any of its executive officers which has not been disclosed herein or
in writing by them to UniversityCare and which materially adversely affects, or
in the future in their opinion may, insofar as they can now foresee, materially
adversely affect the business, properties, assets or condition, financial or
other, of Doctors. Without limiting the foregoing, Doctors has no knowledge that
there exists, or there is pending or planned, any patent, invention, device,
application or principle or any statute, rule, law, regulation, standard or code
which would materially adversely affect the business, operations, affairs or
financial condition of Doctors.

             2.20  Employee Benefit Plans. For purposes of this Agreement, the
term "Employee Plan" includes any pension, retirement, savings, disability,
medical, dental or other health plan, life insurance (including any individual
life insurance policy as to which Doctors makes premium payments whether or not

plan, profit sharing, deferred compensation, stock option, bonus or other
incentive plan, vacation benefit plan, severance plan or other employee benefit
plan or arrangement (whether written or arising from custom), including, without
limitation, any employee pension benefit plan ("Pension Plan") as defined in

("ERISA"), and any employee welfare benefit plan as defined in Section 3(1) of
ERISA ("Welfare Plan"), whether or not any of the foregoing is funded, and
whether written or oral, (i) to which Doctors is a party or by which Doctors (or
any of its respective rights, properties or assets) is bound or (ii) with
respect to which

                                      -10-


<PAGE>

Doctors has made payments, contributions or commitments or may otherwise have
any liability (including any such plan or arrangement formerly maintained by
Doctors. There are no Employee Plans other than those listed in Schedule 2.20.

                           2.21.1   To Doctor's  best  knowledge  and belief,
no officer or employee of Doctors is, or is now expected to be, in violation of
any term of any employment contract, patent disclosure agreement, proprietary
information agreement, non-competition agreement, confidentiality agreement, or
any other similar contract or agreement or any restrictive covenant relating to
the right of any such officer or employee to be employed by Doctors because of
the nature of the business conducted or to be conducted by Doctors or relating
to the use of trade secrets or proprietary information of others, and to
Doctors's best knowledge and belief, the continued employment of Doctors's
officers and employees does not subject Doctors or the Purchaser to any
liability with respect to any of the foregoing matters.

                           2.21.2  To the best  knowledge  of  Doctors,  no
officer  of  Doctors,  nor any Key Employee of Doctors whose termination, either
individually or in the aggregate, would have an adverse effect on Doctors, has
any present intention of terminating his employment with Doctors.

             2.22  Transactions with Affiliates. Except as set forth in Exhibit
2.22, there are no loans, leases, royalty agreements or other continuing
transactions between (a) Doctors or any of its customers or suppliers, and (b)
any officer, employee or director of Doctors or any Person owning five percent
(5%) or more of the capital stock of Doctors or any member of the immediate
family of such officer, employee, director or stockholder or any corporation or
other entity controlled by such immediate family of such officer, employee,
director or stockholder.

             2.23  Securities Act of 1933. Doctors has complied and will comply

                  among   Doctors  and  certain  of  its stockholders."

for the  Series B Stock was equal to MMS's original purchase price plus the
agreed upon return on investment; and

                                    8.2.2.3    the sale was to an  unrelated
Maryland  health  care  organization, provided that MMS will not disclose the
name of the purchaser;

provided, however, that MMS shall not make any press or other media release
concerning the Agreement or the transactions described herein;

                                    8.2.3    With respect to rating  agencies,
MMS may disclose the Closing  Date, the  actual  Purchase  Price,  and,  to the
extent  that  such  rating  agencies  are  bound by an  obligation  of
confidentiality and non-disclosure, the name of the purchaser and the Bill of
Sale described below; and

                                    8.2.4    With  respect to the Maryland
Insurance  Department  (the  "Insurance Department"),  UniversityCare  and MMS
shall execute and deliver at Closing a Bill of Sale setting forth the number of
shares sold by MMS and the Purchase Price and that the Purchase  Price  reflects
MMS's original  purchase price plus the  agreed  upon  return on  investment.
MMS may submit the Bill of Sale to the  Insurance  Department.  MMS agrees that
it will not submit any additional  information to the Insurance  Department
unless: (i) it has received a request, in writing, from the Insurance
Department;  and (ii) it has notified  UniversityCare prior

                                      -21-

to filing any response to such  request,  in order to permit  UniversityCare  to
obtain such confidentiality  treatment  of such information as is reasonably
possible under the circumstances.

             8.3  Fair Market Value of Shares; No Impermissible Activities.
Doctors and UniversityCare agree that the fair market value of the Series B
Stock was determined in an arms length transaction and is not determined in a
manner that takes into account the volume or value of any referrals or business
otherwise generated between the parties for which payment may be made, in whole
or in part, under Medicare or any State health care program, as defined under
Section 1128B of the Social Security Act. Doctors and UniversityCare further
agree that the purchase of Series B Stock and any related transaction between
the parties or affiliates thereof, do not involve the counseling or promotion of
a business arrangement or other activity that violates any State or federal law.
Doctors and UniversityCare agree that, to the best of its respective knowledge,
none of the proceeds being paid to MMS will be paid or become payable to Doctors
as an inducement to make referrals to UniversityCare or any affiliate thereof.

                                  TERMINATION


             9.1  Termination and Abandonment. This Agreement may be terminated
and the transactions abandoned by mutual consent of the parties, or by any of
the parties by notice to the others:

                           9.1.1   in the event that any of the conditions
precedent to the performance of the obligations of the party giving such notice
shall not have been fulfilled and cannot be fulfilled on or prior to the Closing
Date and shall not have been waived by such party, or if a default shall be made
by another party in the observance or in the due and timely performance of any
of the covenants and agreements herein contained that cannot be cured on or
prior to the Closing Date and shall not have been waived by the party giving
such notice; provided that nothing provided herein shall be construed as
permitting a party to terminate when an affiliate of the party has been in
default;

                           9.1.2   in the  event of the  institution  or
serious  threat  by any  governmental authority or by any other person of
litigation or proceedings against any of the parties to enjoin, hinder or delay
or to obtain damages or other relief in connection with this Agreement or the
transactions contemplated herein; or

                           9.1.3   if  any  consent  or  approval  which  is
necessary  to  the   transactions contemplated herein or the continuing
business, properties or prospects of Doctors shall have been refused or
withdrawn by any governmental authority having jurisdiction.

                          Indemnification and Claims.

             10.1  Indemnification by Doctors. Doctors shall defend and
indemnify and hold UniversityCare, each of its affiliates, and their respective
officers, directors, employees and agents, and each of their heirs, executors,
successors and assigns wholly harmless from and against any and all liabilities,
losses, damages, costs (including, without limitation, court costs and costs of
appeal), and expenses (including, without limitation, reasonable attorneys'
fees) incurred or maintained by UniversityCare, its affiliates, and their
respective directors, officers, employees and agents, and each of their heirs,
executors, successors and assigns, because of any inaccuracy in, or material
breach or violation of, the representations, warranties, and covenants made by
Doctors in this Agreement.

             10.2  Indemnification by MMS. MMS shall defend and indemnify and
hold UniversityCare, each of its affiliates, and their respective officers,
directors, employees and agents, and each of their heirs, executors, successors
and assigns wholly harmless from and against any and all liabilities, losses,
damages, costs (including, without limitation, court costs and costs of appeal),
and expenses (including, without limitation, reasonable attorneys' fees)
incurred or maintained by UniversityCare, its affiliates, and their respective
directors, officers, employees and agents, and each of their heirs, executors,
successors and assigns, because of any inaccuracy in, or material breach or
violation of, the representations, warranties, and covenants made by MMS in this
Agreement.

             10.3  Indemnification by UniversityCare. UniversityCare shall
defend and indemnify Doctors and MMS and hold Doctors and MMS, their affiliates,
each of their respective directors, officers, employees and agents, and each of
their heirs, executors, successors and assigns wholly harmless from and against
any and all losses, liabilities, damages, costs (including, without limitation,
court costs and cost of appeal) and expenses (including, without limitation,
reasonable attorneys' fees of one counsel) that either Doctors or MMS incurs as
a result of, or with respect to any inaccuracy in or breach of any
representation, warranty, covenant or agreement of UniversityCare contained in
this Agreement.

             10.4  Limitation on and Expiration of Indemnification.
Notwithstanding anything in this ARTICLE 10 to the contrary, Doctors's and MMS's
rights to indemnification from UniversityCare and UniversityCare's rights to
indemnification from Doctors and/or MMS shall be limited as follows:

                                      -23-

<PAGE>

                                    10.4.1 all rights of the parties hereto to
indemnification hereunder for breaches of representations and warranties shall
expire two (2) years after the Closing Date; provided, however, if, prior to
such expiration, a state of facts shall have become known which threatens to
give rise to a liability against which any party hereto would be entitled to
indemnification hereunder and the indemnified party shall have given notice of
such facts to the indemnifying party, then the rights of the indemnified party
to indemnification with respect to such liability shall continue until such
liability shall have been finally determined and disposed of; and provided,
however, a party's rights to indemnification upon the other party's failure to
comply with this ARTICLE 10 shall survive until the expiration of the applicable
period of limitations.

                                    10.4.2 No party shall be entitled to
indemnification pursuant to Sections 10.1(a) or 10.2(b) unless and until the
aggregate amount of damages to which the foregoing indemnity relates, sustained
by such party with respect to any individual claim exceeds Ten Thousand Dollars
($10,000), and then only to the extent that such damages exceed in the aggregate
Twenty-five Thousand Dollar ($25,000). Further, a breach of any of the
materiality standards set forth in this Agreement shall be defined as damages
with respect to any individual claim which exceeds Ten Thousand Dollars
($10,000).

             10.5  Notice and Control of Litigation. If any claim or liability
is asserted in writing against a party entitled to indemnification under this
ARTICLE 10 (the "Indemnified Party") which would give rise to a claim under this
ARTICLE 10, the Indemnified Party shall notify the person providing the
indemnity ("Indemnifying Party") in writing of the same within fifteen (15) days
of receipt of such written assertion of a claim or liability. The Indemnifying
Party shall have the right to defend a claim and control the defense, settlement
and prosecution of any litigation. If the Indemnifying Party, within ten (10)
days after notice of such claim, fails to defend such claim, the Indemnified
Party will (upon further notice to the Indemnifying Party) have the right to
undertake the defense, compromise or settlement of such claim on behalf of and
for the account and risk of the Indemnifying Party, subject to the right of the
Indemnifying Party to assume the defense of such claim at any time prior to
settlement, compromise or final determination thereof. Anything in this Section
10.5 notwithstanding, (i) if there is a reasonable probability that a claim may
materially and adversely affect the Indemnified Party other than as a result of
money damages or other money payments, the Indemnified Party shall have the
right, at its own cost and expense, to defend, compromise and settle such claim,
and (ii) the Indemnifying Party shall not, without the written consent of the
Indemnified Party settle or compromise any claim or consent to the entry of any
judgment which does not include as an unconditional term thereof the giving by
the claimant to the Indemnified Party a release from all liability in respect to
such claim. All parties agree to cooperate fully as necessary in the defense of
such matters. Should the Indemnified Party fail to notify the Indemnifying Party
in the time required above, this indemnity shall terminate and be of no further
force and effect with respect to the subject matter of the required notice in
the event that the Indemnified Party's failure to notify in the time

                                      -24-

<PAGE>

required above materially adversely affects the Indemnifying Party's ability to
defend such matter.

<PAGE>

Board shall be vested in and exercised by an executive committee of the Board
(the "Executive Committee"). The Shareholders agree to vote all of their Voting
Shares for directors who agree to vote to cause the management of the Company by
its Board to be conducted in accordance with the provisions of this Section

connection therewith and, subject to the exercise of applicable fidicuary
duties, shall act in a manner consistent with such recommendation. The Executive
Committee shall have seven members and shall be comprised of:

         Officer of the Company and approved by a majority of the Class B
         Directors then in office.

necessary to cause at least one Beacon Director or Beacon Designee to be
appointed to each committee of the Board and to each of the boards of directors
or other similar managing bodies (and any committee thereof) of each of the
Subsidiaries of the Company. The Company shall, to the extent requested by
Beacon, elect as the board of directors of each Subsidiary those persons who are
at the time directors of the Company as provided in Section 3.1. Neither
Beacon's ownership of Stock nor its designation of members of the Board shall
require Beacon to present to the Company any opportunities of which Beacon or
its Affiliates become aware through means other than Beacon's membership on the
Board or as a shareholder of the Company.

                  3.3.     Vacancies; Removal.

to serve as a director of the Company or any Subsidiary for any reason, the
vacancy resulting

                                      -9-

<PAGE>

thereby shall be filled by another person designated in accordance with the
provisions of Section 3.1 or Section 3.2(b), as applicable and the Restated
Articles.

                  (b) Removal. No director or Beacon Designee shall be removed
from office without the consent of the Shareholders entitled to designate such
director or, in the case of a Beacon Designee, Beacon, so long as such
Shareholder, or in the case of a Beacon Designee, Beacon, is entitled to
designate such director or Beacon Designee, as applicable.

                  3.4. Non-Voting Observer. The Company agrees that so long as
Beacon holds 5% or more of the outstanding Common Stock, Beacon shall be
entitled to have up to two observers (each, a "Non-Voting Observer") selected by
Beacon present at all meetings of the Board, and each committee thereof
(including, without limitation, the Executive Committee), and such observer
shall have the same access to information concerning the business and operations
of the Company at the same time as directors of the Company and shall be
entitled to participate in discussions and consult with, and make proposals and
furnish advice to, the Board or committee, as the case may be, without voting;
provided, however, that the Board or committee, as the case may be, shall be
under no obligation to take any action with respect to any proposals made or
advice furnished by any Non-Voting Observer, other than to give due
consideration thereto. The Company shall notify each Non-Voting Observer of
every meeting (or action by written consent) of the Board, or committee, as the
case may be, in the same manner that notice is required to be provided to
members of the Board pursuant to the By-Laws or, if such notice under the
circumstances is not practicable, as soon before the meeting (or distribution)
as is practicable, provided that nothing in this Section 3.4 shall be construed
in any way to authorize or allow a party hereto not to comply with its
obligations hereunder or release it from liability and equitable remedy in the
case of a breach. Each such Non-Voting Observer shall execute a confidentiality
agreement in such form as prescribed by the Company.

                  3.5. Representative. In the event that, after receiving proper
notice of a meeting of the Board, or any committee thereof, or a meeting of any
board of directors or similar managing body of any of the Company's Subsidiaries
in accordance with such entity's by-laws, any Beacon Director, Beacon Designee
or Non-Voting Observer determines that he or she is unable to attend such
meeting, Beacon shall have the right to designate a representative to attend and
observe such meeting on behalf of such Beacon Director, Beacon Designee or
Non-Voting Observer, as the case may be, who shall be entitled to fully
participate in such meeting to the full extent he or she could participate if he
or she were a Non-Voting Observer.

                  3.6. Board and Committee Meetings. The Company shall cause the
Board to hold regular meetings of its Board and the Executive Committee on at
least a quarterly basis. The Company agrees, and shall cause the By-laws to be
amended to the extent necessary to provide that, so long as Beacon meets or
exceeds the Pre-IPO Threshold or the Post-IPO Threshold, as applicable, each
Beacon Designee and each Beacon Director shall have the right, upon reasonable
notice, to call meetings of the Board and of each committee of the Board on
which he or she is a member. The

                                      -10-

<PAGE>

Company agrees that any Non-Voting Observer shall have the right to request that
the Chairman of the Board or the Chief Executive Officer of the Company call a
meeting of the Board and of each committee of the Board.

                  3.7.  Directors' Indemnification.

                  (a) The Company shall obtain and cause to be maintained in
effect, with financially sound insurers, a policy of directors' and officers'
liability insurance covering each member of the Board, each Beacon Designee and
each Non-Voting Observer in an amount of at least $3 million per occurance and
$5 million in the aggregate.

                  (b) The Restated Articles, By-laws and other organizational
documents of the Company and each of its Subsidiaries shall at all times, to the
fullest extent permitted by law, provide for indemnification of, advancement of
expenses to, and limitation of the personal liability of, the members of the
Board and each committee thereof, and the members of the boards of directors or
other similar managing bodies of each of the Company's Subsidiaries and such
other persons, if any, who, pursuant to a provision of such Restated Articles,
By-laws or other organizational documents, exercise or perform any of the powers
or duties otherwise conferred or imposed upon members of the Board and each
committee thereof, or the boards of directors or other similar managing bodies
of each of the Company's Subsidiaries. Any Non-Voting Observer shall be entitled
to indemnification from the Company to the maximum extent permitted by law as
though he or she were an officer or agent of the Company or any of its
Subsidiaries. Such provisions may not be amended, repealed or otherwise modified
in any manner adverse to any member of the Board or any committee thereof, or
any member of the boards of directors or other similar managing bodies of any of
the Company's Subsidiaries, until at least six years following the date that
Beacon is no longer entitled to designate or nominate any Beacon Director,
Beacon Designee or Non-Voting Observer.

                  (c) Each member of the Board, Beacon Designee and Non-Voting
Observer is intended to be a third-party beneficiary of the obligations of the
Company pursuant to this Section 3.7, and the obligations of the Company
pursuant to this Section 3.7 shall be enforceable by each member of the Board,
Beacon Designee and Non-Voting Observer.

                  3.8.  Irrevocable Proxy. In order to secure each Shareholder's
obligation to vote his Voting Shares in accordance with the provisions of this
Section 3 pursuant to which Beacon has rights hereunder, each Shareholder hereby
irrevocably appoints Beacon as his, her or its true and lawful proxy and
attorney-in-fact, with full power of substitution, to vote all of his Voting
Shares of the Company for the election of each Beacon Director and each Beacon
Designee as a member of the Board and to take all such other actions as are
necessary to enforce the rights of Beacon under this Section 3. Such irrevocable
proxy shall become effective and Beacon may exercise the irrevocable proxy
granted to it hereunder at any time any Shareholder fails to comply with any
provision of this Agreement granting Beacon rights under this Section 3. The

                                      -11-

<PAGE>

proxies and powers granted by each Shareholder pursuant to this Section 3.8 are
coupled with an interest and are given to secure the performance of the
Shareholders' obligations to Beacon under this Section 3. Such proxies and
powers shall survive the death, incompetence and disability of each Shareholder.
Such proxies and powers will be effective until Beacon no longer owns at least
the Post-IPO Threshold, at which time such proxies and powers shall terminate.

                  3.9. Contractual Management Rights. The Company and each of
the Shareholders acknowledge that the provisions of this Agreement, including,
without limitation, this Section 3, are intended, among other things, to provide
Beacon with "contractual management rights" within the meaning of the Employee
Retirement Income Security Act of 1974, as amended, and the regulations
promulgated thereunder.

                  3.10.  Expenses. The Company shall pay the reasonable
out-of-pocket expenses incurred by each Beacon Director, Beacon Designee and
Non-Voting Observer, and any representative of the foregoing, in connection with
performing his or her duties, including without limitation the reasonable
out-of-pocket expenses incurred by such person attending meetings of the Board
or any committee thereof or meetings of any board of directors or other similar
managing body (and any committee thereof) of any Subsidiary of the Company.

                  3.11. Cooperation. Each Shareholder shall vote all of its
Voting Shares and shall take all other necessary or desirable actions within its
control (including, without limitation, attending all meetings in person or by
proxy for purposes of obtaining a quorum, executing all written consents in lieu
of meetings and voting to remove members of the Board, as applicable), and the
Company shall take all necessary and desirable actions within its control
(including, without limitation, calling special Board and shareholder meetings
and voting to remove members of the Board, as applicable), to effectuate the
provisions of this Section 3.

                  3.12. Reincorporation. The Company and each Shareholder agree
that if the Company's state of incorporation has not been moved to Delaware by
the initial closing under the Purchase Agreement, then, if Beacon requests, the
Company and each Shareholder shall use their best efforts to so reincorporate
the Company within 60 days after such closing. If such reincorporation is not
effected within such 60 day period, the Company and the Shareholders agree to
take all such action as may be necessary or appropriate to promptly amend the
Restated Articles and this Agreement to increase the size of the Board to a size
sufficient to permit Beacon to appoint additional directors if the events
described in Article V.3 of the Restated Articles occur such that Beacon's
directors will, in such circumstances, represent more than 50% of the members of
the Board.

                  Section 4. Restrictions on Transfers of Stock.

                  (a) No Shareholder shall Transfer any Stock, whether owned on
the date hereof or acquired hereafter, without first, if applicable, complying
with the

                                      -12-

<PAGE>

provisions of Section 6 hereof and then, in each case as applicable, complying
with the provisions of Section 7 hereof; provided that Beacon may Transfer up to
500,000 of its shares of Stock to any Affiliate or business associate of Beacon
or its Affiliates without the need to comply with the provisions of Sections 6
or 7 (but, subject to the provisions of Section 4(b)). Notwithstanding any other
provision hereof, no Management Shareholder may Transfer any Stock if, after
giving effect to such Transfer, such Management Shareholder shall have
Transferred in the aggregate an amount of Stock in excess of 5% of the
outstanding Stock held by such Management Shareholder as of the date hereof,
except that (i) from and after a Qualified IPO a Management Shareholder may
Transfer Stock, (ii) a Management Shareholder may Transfer Stock in connection
with the bona fide merger of the Company or bona fide sale of all or
substantially all of the assets or equity securities of the Company, and (iii) a
Management Shareholder may Transfer Stock as set forth in Section 5. Except with
respect to Transfers of Stock by Management Shareholders described in Section 5,
each Management Shareholder shall, prior to any Transfer of Stock permitted by
this Section 4, comply with the provisions of Sections 6 and 7 hereof, in each
case as applicable.

                  (b) Except in connection with a Public Sale, any Transferee of
Stock (including any Transferee that is an Affiliate of a Transferor) who is not
a Shareholder shall upon consummation of, and as a condition to, such Transfer
execute and deliver to the Company (which the Company shall then deliver to all
other Shareholders) an agreement in form and substance satisfactory to Beacon
pursuant to which it agrees to be bound by the terms of this Agreement for the
benefit of the parties hereto and such Transferee shall thereafter be deemed to
be a Shareholder for all purposes of this Agreement.

                  (c) Any Transfer or attempted Transfer of Stock in violation
of any provision of this Agreement shall be void, and the Company shall not
record such Transfer on its books or treat any purported Transferee of such
Stock as the owner of such Stock for any purpose.

                  Section 5.   Management Shareholders.

                  (a) Involuntary Transfers. Upon the occurrence of an
Involuntary Transfer of the Stock of any Management Shareholder (the
"Involuntary Transfer Shareholder"), the Company shall have the option (but not
the obligation), for a period of 30 days from the date of such occurrence, to
purchase such Stock by providing written notice to such effect to such
Involuntary Transfer Shareholder and to any court that has then exercised
jurisdiction over such Involuntary Transfer Shareholder 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 Shareholder shall be obligated,
if the Company 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
Shareholder's name at the price provided in Section 5(d) hereof and upon the
terms provided in Section 5(e) hereof. If the Company elects not to exercise its
option pursuant to this Section 5(a) within such 30-day period, it shall
immediately provide written notice to that effect to all

                                      -13-

<PAGE>

of the other Management Shareholders (the "Non-Involuntary Transfer Management
Shareholders") who shall have the option to purchase, and such Involuntary
Transfer Shareholder 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 5(d)
hereof and upon the terms provided in Section 5(e) hereof. If more than one
Non-Involuntary Transfer Management Shareholder 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 Management Shareholders desiring
to purchase such stock shall be entitled to purchase up to that number of shares
of such Stock that is equal to the product of such Management Shareholder's
percentage share of the outstanding Common Stock then held by such
Non-Involuntary Transfer Management Shareholders desiring to purchase such stock
multiplied by the number of shares of Stock available for purchase from the
Involuntary Transfer Shareholder hereunder. The Non-Involuntary Transfer
Management Shareholders shall have the right to exercise their respective
options hereunder for a period of 30 days following their receipt of notice from
the Company that it has elected not to purchase such Stock.

                  (b)  Termination of Employment of Management Shareholders
other than Rifkin or Kimmel.

                                    (i) Termination Without Cause; Death;
                  Disability. If the employment of a Management Shareholder
                  other than Scott Rifkin or Alan Kimmel with the Company is
                  terminated (A) without "cause" as contemplated in such
                  Management Shareholder's employment agreement, or (B) by the
                  Management Shareholder for any reason constituting
                  "constructive termination" as defined in such Management
                  Shareholder's employment agreement, then the remaining
                  Management Shareholders shall have the option for a period of
                  60 days from the date of such termination to purchase (in such
                  proportions as they shall agree or, if they cannot agree, in
                  proportion to their ownership of outstanding Common Stock
                  other than the Stock of the terminated Management
                  Shareholder), and if such option is exercised, the terminated
                  Management Shareholder may, but shall not be obligated to,
                  sell all of the Stock held by such terminated Management
                  Shareholder (the "Terminated Manager's Stock") on terms
                  substantially identical to those set forth in Section 5(e)
                  (other than subsections (iii) and (iv) thereof) and at the
                  price set forth in Section 5(d). If the employment of a
                  Management Shareholder other than Scott Rifkin or Alan Kimmel
                  with the Company is terminated due to death or Disability (as
                  such terms are defined in such Management Shareholder's
                  employment agreement, then such Management Shareholder's or
                  such Management Shareholder's personal representative may, for
                  a period of sixty (60) days from the date of appointment of
                  such personal representative or disability, as the case maybe,
                  offer to the remaining Management Shareholder's the option to
                  purchase (in such proportions as they shall agree or, if they
                  cannot agree, in proportion to their ownership of outstanding
                  Common Stock other than the Stock of the deceased or disabled
                  Management Shareholder) and if

                                      -14-

<PAGE>

                  such option is exercised, the decreased or disabled Management
                  Shareholder may, but shall not be obligated to, sell all of
                  such Terminated Manager's Stock on terms substantially
                  identical to those set forth in Section 5(e) (other than
                  subsections (iii) and (iv) thereof) and at the price set forth
                  in Section 5(d) If all of the Terminated Manager's Stock is
                  not purchased by the other Management Shareholders, the
                  Company shall, upon such Management Shareholder's request,
                  purchase, within 90 days after the date of said termination,
                  and such terminated Management Shareholder shall sell, all of
                  the Terminated Manager's Stock at the price set forth in
                  Section 5(d), and upon the terms set forth in Section 5(e)
                  hereof.

                                    (ii) Termination Under other Circumstances.
                  If the employment of a Management Shareholder other than Scott
                  Rifkin or Alan Kimmel with the Company is terminated (A) by
                  the Company for "cause" as contemplated by his employment
                  agreement, or, if no such agreement is in effect, for "good
                  cause" under applicable law, or (B) by the Management
                  Shareholder for reasons not constituting "constructive
                  termination" under his employment agreement, then the Company
                  shall have the option (but not the obligation) to purchase,
                  within 90 days after the date of such termination, and, if
                  such option is exercised, such Management Shareholder shall
                  sell, all of the shares of Stock held by such Management
                  Shareholder at a price equal to the lesser of such Management
                  Shareholder's acquisition cost for his stock or $1.00 per
                  share, and upon the terms set forth in Section 5(e) hereof. If
                  the employment of a Management Shareholder other than Scott
                  Rifkin or Alan Kimmel is terminated due to expiration of the
                  term of his employment agreement, then the Company shall have
                  the option (but not the obligation) to purchase, within 90
                  days after the date of such termination, and, if such option
                  is exercised, such Management Shareholder shall sell, all of
                  the shares of Stock held by such Management Shareholder at a
                  price determined pursuant to Section 5(d) and upon the terms
                  set forth in Section 5(e).

                                     (iii) Change in Control. If the employment
                  of a Management Shareholder other than Scott Rifkin or Alan
                  Kimmel with the Company is terminated by the Company without
                  "cause" as contemplated in such Management Shareholder's
                  employment agreement or by such Management Shareholder for
                  reasons constituting "constructive termination" under such
                  Management Shareholder's employment agreement, and there
                  occurs a Change in Control within the first twelve months
                  following the date of such termination, the Company agrees to
                  pay or cause to be paid to such terminated Management
                  Shareholder (or to his heirs, legatees and/or guardians), in
                  addition to the purchase price for such terminated Management
                  Shareholder's Stock, the value of such terminated Management
                  Shareholder's share of any consideration that would have been
                  payable to such terminated Management Shareholder

                                      -15-

<PAGE>

                  (less any such consideration actually received by such
                  Management Shareholder as a result of a sale of his Stock,
                  whether to another Management Shareholder, the Company or
                  another person) upon, and as a result of, such a Change in
                  Control of the Company within such twelve-month period. Such
                  payment shall be made by the Company when and as the Company
                  or the other the Company's remaining Shareholders receive
                  consideration as a result of such a Change in Control, and
                  shall be paid by the Company based upon such terminated
                  Management Shareholder's pro-rata equity interest in the
                  Company at the time of termination. Any payment by the Company
                  pursuant to this Section as a result of a Change in Control
                  may, at the Company's option, be made by delivery of any
                  combination of cash, promissory notes 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, as
                  amended (the "Code"), or an appropriate in-kind distribution
                  of any consideration received by the Company or its
                  Shareholders as a result of such Change in Control.

                  (c)  Termination of Employment of Rifkin and Kimmel.

                                    (i) Termination of Employment For Good
                  Cause. If the employment of either Scott Rifkin or Alan Kimmel
                  (as the case may be, a "Terminated Senior Manager") with the
                  Company is terminated (A) by the Company for any of the
                  specific reasons enumerated in Section 4.3(a) of their
                  respective employment agreements (or, if no such agreement is
                  then in effect, for "good cause" under applicable law) or (B)
                  by the Terminated Senior Manager for any reason not
                  constituting "constructive termination" as defined in Section
                  4.4(b) of such Terminated Senior Manager's employment
                  agreement, then the Company shall have the option (but not the
                  obligation) to purchase, within 90 days after the date of
                  termination, and, if such option is exercised, such Terminated
                  Senior Manager shall sell, all of the Stock then registered in
                  such Terminated Senior Manager's name or held, in trust or
                  otherwise, for his benefit at a price equal to the lesser of
                  such Terminated Senior Manager's acquisition cost for such
                  Stock or $1.00 per share, and upon the terms provided in
                  Section 5(e) hereof; provided, however, that the provisions of
                  this Section 5(c)(i) shall not apply to any shares of capital
                  stock of the Company held by such Terminated Senior Manager on
                  January 31, 1997 (or received as a distribution on or in
                  respect of such shares after January 31, 1997 as the result of
                  any recapitalization, stock split or similar event).

                                    (ii) Death; Disability. Upon each of (A) the
                  Disability of either Scott Rifkin or Alan Kimmel (as the case
                  may be, a "Disabled Shareholder"), and (B) such Shareholder's
                  death, and the appointment and qualification of his personal
                  representative, for a period of 60 days from the date of such
                  appointment and qualification or Disability, as the case may
                  be, such personal representative or such Disabled Shareholder,
                  as the case may be, may offer to the other Management
                  Shareholders the

                                      -16-

<PAGE>

                  option to purchase (in such proportions as they shall agree
                  upon, or if they cannot agree, in proportion to their
                  respective ownership of outstanding Common Stock), all of the
                  shares of Stock held by such personal representative, or
                  Disabled Shareholder, on terms substantially identical to
                  those set forth in Section 5(e) hereof (other than subsections
                  (iii) and (iv) thereof) and at a price determined in
                  accordance with the terms of Section 5(d) hereof. If the
                  option to purchase all of the shares of Stock so offered is
                  not exercised or accepted within such 60-day period, then such
                  Disabled Shareholder or such personal representative, as the
                  case may be, shall be entitled to sell, by providing written
                  notice to the Company, and the Company shall be required to
                  purchase upon receipt of such notice, all or a portion of such
                  shares of Stock held by the Disabled Shareholder or such
                  personal representative as such number of shares set forth in
                  such written notice, at the price and upon the terms provided
                  in Sections 5(d) and 5(e) hereof.

                                    (iii) Termination of Employment Under Other
                  Circumstances. If a Terminated Senior Manager's employment is
                  terminated (A) by the Company without "good cause" as
                  contemplated by his employment agreement or (B) by such
                  Terminated Senior Manager for reasons constituting
                  "constructive termination" under his employment agreement,
                  then the Company shall purchase, within 90 days after the date
                  of such termination, and such Terminated Senior Manager shall
                  sell, Stock acquired by such Terminated Senior Manager after
                  January 31, 1997 (other than Stock acquired pursuant to a
                  distribution, made with respect to a recapitalization, stock
                  split or similar event, on or in respect of Stock held on
                  January 31, 1997) at the price set forth in Section 5(d) and
                  subject to the terms set forth in Section 5(e). If the
                  employment of a Terminated Senior Manager is terminated due to
                  expiration of the term of his employment agreement, then the
                  Company shall have the option (but not the obligation) to
                  purchase, within 90 days after the date of such termination,
                  and, if such option is exercised, such terminated Senior
                  Manager shall sell, all of the shares of Stock held by such
                  terminated Senior Manager or by a trust or otherwise for his
                  benefit, at a price determined pursuant to Section 5(d) and
                  upon the terms set forth in Section 5(e).

                  (d) Purchase Price. With respect to purchases of Stock made
pursuant to Sections 5(a), 5(b)(i), the second sentence of 5(b)(ii), and
5(c)(ii) and (iii), if the purchaser of Stock hereunder, on the one hand, and
the Transferring Shareholder, on the other hand, agree in writing as to the
purchase price for such Stock, such agreed price shall be the purchase price for
such Stock. If the purchase price of such Stock is not agreed upon (x) with
respect to an event described in Sections 5(a) or 5(b)(i), within 30 days from
the date of such event and (y) with respect to an event described in Sections
5(c)(ii) and (iii), within 30 days after the receipt of the notice required to
be determined thereunder or, with respect to the death of a Management
Shareholder other than Scott Rifkin or Alan Kimmel, after the appointment and
qualification of such

                                      -17-

<PAGE>

deceased Management Shareholder's personal representative, then, the purchase
price of such Stock shall be its Fair Market Value. The Transferring Shareholder
and the Company shall each pay one-half of all expenses incurred in connection
with the determination of the Fair Market Value of Stock under this Section
5(d).

                  (e) Payment of Purchase Price. The payment of any purchase
price for Stock Transferred pursuant to this Section 5 hereof may be made on
such terms as are agreed upon by the parties or, absent such agreement, as
follows:

                                    (i) Cash. Subject to the terms of
                  subparagraph (iv) hereof and, with respect to any Involuntary
                  Transfer, subject to such other terms and conditions as are
                  required by any court exercising jurisdiction over any
                  Involuntary Transfer Shareholder with respect to its Stock or
                  over any assignee, trustee in bankruptcy or
                  successor-in-interest with respect to such Involuntary
                  Transfer Shareholder, as the case may be, (A) in the event of
                  any Transfer pursuant to this Section 5 (other than as a
                  result of the death of a Management Shareholder), (1) if the
                  Company is the purchaser, 10% of the total purchase price of
                  the Stock shall be paid in cash by bank wire transfer by the
                  Company on the Closing Date, and (2) if anyone other than the
                  Company is the purchaser, the entire amount of the purchase
                  price of the Stock shall be paid in cash by bank wire transfer
                  by such purchaser(s) on the Closing Date, and (B) in the event
                  of any Transfer as a result of the death of a Management
                  Shareholder, the Company shall pay in cash by bank wire
                  transfer on the Closing Date the greater of (1) the proceeds
                  of any life insurance policy or policies purchased by the
                  Company as contemplated by Section 5(f) (but not in excess of
                  the purchase price to be paid by the Company pursuant to this
                  Section 5) and (2) 10% of the total purchase price to be paid
                  by the Company with respect to the Stock formerly held by such
                  deceased Management Shareholder. Notwithstanding the
                  foregoing, if the Company is a purchaser of Stock pursuant to
                  this Section 5 but is prohibited by law and/or the Restated
                  Articles to make all or any portion of any cash payment
                  otherwise payable on the Closing Date with respect to the
                  purchase of such Stock, the Company shall pay the maximum
                  amount permitted by law and the Restated Articles, if any, and
                  the balance of such purchase price shall be made in accordance
                  with Section 5(e)(ii).

                                    (ii) Promissory Note. After payment in cash
                  of the amount set forth in Sections 5(e)(i), the balance of
                  the purchase price to be paid by the Company pursuant to this
                  Section 5 shall be represented by a promissory note of the
                  Company, payable in seven equal annual installments of
                  principal and interest, the first of which shall be due and
                  payable on the first anniversary of delivery of the Note, and
                  otherwise in form and substance satisfactory to the Company
                  and the Transferring Shareholder or the representative thereof
                  (the "Note"). Interest shall accrue on, and be payable with,
                  the unpaid balance of the Note from the Closing Date at a rate
                  equal to the applicable federal rate for long-term

                                      -18-

<PAGE>

                  debt instruments under Code Section 1274(d)(1) in effect as of
                  the Closing Date. As security for payment of the amounts due
                  under the Note, the Company shall, to the extent provided by
                  agreements and instruments to which the Company is a party,
                  pledge to the Transferring Shareholder the Stock being
                  purchased pursuant to this Section 5 until such time as all
                  payments due thereunder have been paid in full; provided that
                  such selling Shareholder shall not be entitled to exercise any
                  voting or other rights with respect to such shares of Stock so
                  long as the Company is not in default of any payment due under
                  such note; provided, further, that the Company's obligations
                  under the Note shall be expressly subordinated to the rights
                  and preferences, including, without limitation, with respect
                  to dividends and liquidation, of the Series D Preferred.

                                    (iii) Debt Due From Shareholder. Any debt
                  due by a Transferring Shareholder to the Company shall be
                  payable according to its terms, as shall any debt due by the
                  Company to the Transferring Shareholder; provided, however,
                  that, regardless of the terms of any such debt due by the
                  Shareholder to the Company, any cash payment due under Section
                  5(e)(i), as well as any insurance proceeds payable under
                  Section 5(f) with respect to the purchase of the Transferring
                  Shareholder's Stock, first, shall be applied to offset any
                  such indebtedness until all such indebtedness is fully
                  discharged and, second, as payment of the purchase price for
                  the Transferring Shareholder's Stock. The provisions of this
                  subparagraph (iii) shall also apply to any purchases of Stock
                  by the Company pursuant to Section 6 hereof.

                                    (iv) Involuntary Transfers. The Company
                  shall settle with the 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 such Persons out of the
                  purchase price for such Stock, calculated in accordance with
                  Section 5(d), an amount equal to not more than the sum of the
                  Shareholder's indebtedness and proper items of expense. The
                  Company shall pay the balance, if any, of the purchase price
                  for such Stock to the Transferring Shareholder in accordance
                  with this Section 5(e).

                                    (v) Closing. The closing of a purchase and
                  sale of Stock in accordance with this Section 5 (the
                  "Closing"), unless otherwise provided herein or agreed to in
                  writing by the purchaser(s) and the Transferring Shareholder,
                  shall be held at the principal place of business of the
                  Company (1) 30 days after (x) with respect to any option to
                  purchase such Stock pursuant to this Section 5, the later of
                  (i) the date that the last applicable period for exercising an
                  unexercised option to purchase has lapsed and (ii) the date an
                  option to purchase is accepted or exercised, (y) in connection
                  with the Disability of Scott Rifkin or Alan Kimmel, the date
                  of delivery of the notice required with respect thereto, and
                  (z) the occurrence of any event set forth in Section 5(a)
                  (other than

                                      -19-

<PAGE>

                  death of a Management Shareholder), and (2) with respect to
                  the death of a Management Shareholder, 90 days after the
                  appointment and qualification of such deceased Management
                  Shareholder's personal representative (collectively, the
                  "Closing Date"); provided that, if determination of a purchase
                  price requires a determination of Fair Market Value, then the
                  Closing Date shall not be later than 30 days after such
                  determination. At the Closing, upon payment of the purchase
                  price (including delivery of the Note), the certificates
                  representing the Stock to be purchased and sold pursuant to
                  this Section 5 shall be delivered by the Transferring
                  Shareholder (or his personal or legal representatives, as the
                  case may be) to the purchaser(s) appropriately free and clear
                  of all liens and endorsed in blank for transfer. If the
                  certificates representing any shares of Stock to be so
                  transferred have not been surrendered by the selling
                  Shareholder, all rights of the holder thereof hereunder with
                  respect to said Stock (including, without limitation, voting
                  rights) nonetheless shall cease and terminate without any
                  further action by any Person.

                                    (vi) Certain Limitations. Notwithstanding
                  any other provision of this Section 5 to the contrary, the
                  Company shall not purchase, redeem or otherwise acquire any
                  Stock from any Shareholder at a purchase price equal to the
                  Fair Market Value thereof unless and until any and all accrued
                  but unpaid dividends on Preferred Stock, and any interest
                  having accrued thereon, shall have been paid in full.

                  (f) Life Insurance. As soon as practicable following the
execution of this Agreement, the Company shall use its commercially reasonable
best efforts to purchase a life insurance policy on the life of each Management
Shareholder in such amounts, if any, as the Board deems reasonable and
appropriate. The Company shall be the owner and beneficiary of each such policy,
and any proceeds received thereunder shall be held by the Company in trust for
the purposes of satisfying the Company's obligations under this Section 5. Each
Management Shareholder agrees to cooperate with the Company in obtaining, and in
keeping in full force and effect, all such policies. The Company shall maintain
all each such insurance policy in full force and effect and shall not, without
the prior written consent of the affected Management Shareholder, cancel any
such policy or take or omit to take any action that might give rise to the
termination or cancellation thereof. The Company shall pay premiums on all such
insurance policies as they become due. The Company may, when it deems
appropriate, apply any dividends declared and paid on such policies to the
payment of premiums. Notwithstanding the foregoing, the Company shall have no
obligations under this Section 5(f) with respect to purchasing a life insurance
policy covering the life of a Management Shareholder to the extent a Management
Shareholder is either uninsurable or may not be insured as herein contemplated
upon commercially reasonable terms. If a Management Shareholder Transfers all of
his Stock during his lifetime pursuant to this Section 5, or if this Agreement
is terminated without being superseded by a similar agreement prior to such
Management Shareholder's death, such Management Shareholder, or any designee of
such Management Shareholder, shall have the right, during the 60-day period
beginning with the date of Transfer or

                                      -20-

<PAGE>


termination of this Agreement, to purchase any life insurance policy insuring
the life of such Management Shareholder owned by the Company by paying the
Company an amount equal to the cash surrender value of such insurance 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 that shall have been paid thereon.

                  (g) Irrevocable Proxy. In order to ensure that the Company may
lawfully effect the transactions contemplated by this Section 5, each Management
Shareholder hereby irrevocably appoints the duly elected Secretary of the
Company as his, her or its true and lawful proxy and attorney-in-fact, with full
power of substitution, to vote all of his Voting Shares of the Company to
approve each aspect the transactions contemplated by this Section 5 and to take
all such other actions as are necessary to enforce the rights of the Company
under this Section 5. The Secretary of the Company may exercise the irrevocable
proxy granted to him hereunder at any time a transaction mandated by this
Section 5 requires approval of a Shareholder. The proxies and powers granted by
each Shareholder pursuant to this Section 5 are coupled with an interest and are
given to secure the performance of the Shareholders' respective obligations
under this Section 5. Such proxies and powers shall survive the death,
incompetence and disability of each Shareholder. Such proxies and powers will be
effective until a Qualified IPO, at which time such proxies and powers shall
terminate.

                  Section 6. Rights of First Offer. In addition to and not in
limitation of any other restrictions on Transfers of Stock contained in this
Agreement, any Transfers of Stock by a Shareholder shall be consummated only in
accordance with the following procedures:

                  (a) The Transferring Shareholder shall first deliver to the
Company and each Major Shareholder other than the Transferring Shareholder and,
if the Transferring Shareholder is a Management Shareholder, each other
Management Shareholder (collectively, the "Offered Shareholders") a written
notice (an "Offer Notice") that shall (i) state the Transferring Shareholder's
intention to Transfer Stock to one or more Persons in a bona fide, arm's length
transaction, the amount and type of Stock to be Transferred (the "Subject
Stock"), the purchase price therefor (which shall be payable in cash) and a
summary of the other material terms of the proposed Transfer and (ii) offer the
Company and the Offered Shareholders the option to acquire all or a portion of
such Subject Stock upon the terms and subject to the conditions of the proposed
Transfer as set forth in the Offer Notice (the "Offer). The Offer shall remain
open and irrevocable for the periods set forth below (and, to the extent the
Offer is accepted during such periods, until the consummation of the sale
contemplated by the Offer).

                  (b) Each Offered Shareholder shall have the right and option,
for a period of 20 days after delivery of the Offer Notice (the "Shareholder
Acceptance Period"), to accept all or any part of the Subject Stock so offered
at the cash purchase price and on the terms stated in the Offer Notice. Such
acceptance shall be made by delivering a written notice to the Company and the
Transferring Shareholder within the

                                      -21-

<PAGE>

Shareholder Acceptance Period specifying the maximum number of shares such
Offered Shareholder will purchase (the "First Offer Shares"). If, upon the
expiration of the Shareholder Acceptance Period, the aggregate amount of First
Offer Shares exceeds the amount of Subject Stock, the Subject Stock shall be
allocated among the Offered Shareholders as follows: (i) first, each Offered
Shareholder shall be entitled to purchase no more than its First Offer
Percentage of Subject Stock; (ii) second, if any shares of Subject Stock have
not been allocated for purchase pursuant to (i) above (the "Remaining Shares"),
each Offered Shareholder (an "Oversubscribed Shareholder") that had offered to
purchase a number of shares of Subject Stock in excess of the amount of stock
allocated for purchase to it in accordance with previous allocations of such
shares of Subject Stock, shall be entitled to purchase an amount of Remaining
Shares equal to no more than its First Offer Percentage (treating only
Oversubscribed Shareholders as Offered Shareholders for these purposes) of the
Remaining Shares; and (iii) third, the process set forth in (ii) above shall be
repeated with respect to any shares of Subject Stock not allocated for purchase
until all shares of Subject Stock are allocated for purchase.

                  (c) If the Offered Shareholders shall fail to accept all of
the Subject Stock offered pursuant to, or shall reject in writing, the Offer,
then, upon the earlier of the expiration of the Shareholder Acceptance Period or
the giving of such written notice of rejection or failure to accept such Offer
by the Offered Shareholders, the Company shall have the right and option, for a
period of 20 days (the "Company Acceptance Period"), to accept all or any part
of the Subject Stock not accepted by the Offered Shareholders at the cash
purchase price and on the terms stated in the Offer Notice. Such acceptance
shall be made by delivering a written notice to the Transferring Shareholder and
each of the Offered Shareholders within the Company Acceptance Period.

                  (d) If effective acceptance shall not be received pursuant to
Sections 6(b) and/or 6(c) above with respect to all of the Subject Stock offered
for sale pursuant to the Offer Notice, then the Transferring Shareholder may
Transfer all or any portion of the Stock so offered for sale and not so accepted
at a cash price not less than the price, and on terms not more favorable to the
purchaser thereof than the terms, stated in the Offer Notice at any time within
90 days after the expiration of the Shareholder Acceptance Period (the "Sale
Period"). In the event that all of the Stock is not sold by the Transferring
Shareholder during the Sale Period, the right of the Transferring Shareholder to
Transfer such Stock shall expire and the obligations of this Section 6 shall be
reinstated.

                  (e) All Transfers of Subject Stock to the Company and/or the
Offered Shareholders pursuant to this Section 6 shall be made free and clear of
all liens and shall be consummated contemporaneously at the offices of the
Company on the later of (i) a mutually satisfactory business day within 20 days
after the expiration of the later of the Company Acceptance Period or the
Shareholder Acceptance Period, as applicable, and (ii) the fifth business day
following the expiration or termination of all waiting periods under the HSR Act
applicable to such Transfers, or at such other time and/or place as the parties
may agree. The delivery of certificates or other instruments

                                      -22-

<PAGE>

evidencing such Subject Stock duly endorsed for Transfer shall be made on such
date against payment of the purchase price for such Subject Stock.

                  (f) The requirements of this Section 6 shall not apply to (i)
any Transfer of Stock by a Shareholder to an Affiliate of such Shareholder, (ii)
any Transfer of Stock pursuant to Sections 5 or 8 of this Agreement or (iii) any
Transfer of Stock pursuant to a Public Sale.

                  Section 7.   Tag-Along Rights.

                  (a) No Shareholder shall Transfer any Stock owned by such
Shareholder without complying with the terms and conditions set forth in this
Section 7 (after having complied with the provisions of Section 6).

                  (b) Any Shareholder desiring to Transfer any shares of Stock
(the "Tag-Along Initiator") shall, after expiration of all required notice
periods under Section 6, give not less than 20 days prior written notice of such
intended Transfer to the holders of Preferred Stock (each, a "Tag-Along
Offeree") and to the Company. Such notice (the "Tag-Along Notice") shall set
forth the terms and conditions of such proposed Transfer, including the name of
the proposed Transferee, the number of shares proposed to be Transferred by the
Tag-Along Initiator (the "Tag-Along Shares"), the purchase price per share
proposed to be paid therefor and the payment terms and type of Transfer to be
effectuated. Within 10 days after delivery of the Tag-Along Notice, each
Tag-Along Offeree shall, by written notice to the Tag-Along Initiator and the
Company, have the opportunity and right to sell to the Transferee in such
proposed Transfer (upon the same terms and conditions as the Tag-Along
Initiator) up to that number of shares of such Stock owned by such Tag-Along
Offeree as shall equal the product of (x) a fraction, the numerator of which is
the number of shares of Stock owned by such Tag-Along Offeree as of the date of
the Tag-Along Notice and the denominator of which is the aggregate number of
shares of Stock owned as of the date of the Tag-Along Notice by all Tag-Along
Offerees and the Tag-Along Initiator multiplied by (y) the number of Tag-Along
Shares. No Person may Transfer shares in any transaction that is subject to this
Section 7(b) unless the Transferee agrees to be bound by and complies with the
terms of this Agreement.

                  (c) At the closing of any proposed Transfer in respect of
which a Tag-Along Notice has been delivered, the Tag-Along Initiator together
with the Tag-Along Offeree electing to sell shares, shall deliver, free and
clear of all liens, to the proposed Transferee certificates evidencing the
shares to be sold thereto duly endorsed with Transfer powers and shall receive
in exchange therefore the consideration to be paid or delivered by the proposed
Transferee in respect of such shares as described in the Tag-Along Notice.

                  (d) The provisions of this Section 7 shall not apply to (i)
any Public Sale, (ii) any Transfer by a Shareholder to Affiliates of such
Shareholder or (iii) any Transfers pursuant to Sections 5, 6 or 8.

                  Section 8.   Drag-Along Rights.

                  (a) If Beacon, as long as it holds at least the Pre-IPO
Threshold (the "Drag-Along Initiator"), determines to Transfer or exchange (in a
business combination or otherwise) in one or a series of bona fide arms-length
transactions (collectively, the "Drag-Along Transaction") to an unrelated and
unaffiliated third party all of the shares of Stock held by the Drag-Along
Initiator, then, upon 30 days written notice from the Drag-Along Initiator to
the other Shareholders that shall include reasonable details of the proposed
transaction, including the proposed time and place of closing and the
consideration to be received by the Shareholders, each other Shareholder shall
be obligated to, and shall, sell, Transfer and deliver, or cause to be sold,
Transferred and delivered, to such third party, all of his shares of Stock in
the same transaction at the closing thereof (and will deliver certificates for
all of his shares of Stock at the closing, free and clear of all liens, claims,
or encumbrances) and the consideration paid in such transaction shall first be
applied to pay the liquidation value of all outstanding Preferred Stock in
accordance with the terms thereof and then pro rata among all holders of Stock
on an as converted basis; provided, however, that if within 30 days of receipt
of a notice from the Drag-Along Initiator as provided in this Section 8, the
Company irrevocably commits, in writing, either (i) to use its best efforts to
complete a Qualified IPO or (ii) to purchase all of the shares of Stock of the
Drag-Along Initiator for a cash amount equal to the Drag-Along Value (as defined
below) and the Company demonstrates to the satisfaction of the Drag-Along
Initiator that the Company will be able to complete such purchase, then the
closing of the Drag-Along Transaction shall be suspended until the earlier of
(x) 120 days after the Company so commits or (y) the date the Company determines
that it will be unable to complete the Qualified IPO within such 120-day period.
If the Company fails to either (A) complete the Qualified IPO within 120 days or
(B) purchase the Drag-Along Initiator's shares at the Drag-Along Value, the
Drag-Along Initiator shall have the right to compel the Shareholders to satisfy
the general provisions of this Section 8 in order to consummate the Drag-Along
Transaction without further delay. As used in this Section 8, "Drag-Along Value"
means, with respect to the consideration the Drag-Along Initiator would receive
in connection with the Drag-Along Transaction, the value of such consideration,
which, to the extent other than cash, shall take into account, in addition to
the cash value thereof, the assumptions and reasonable expectations underlying
the Drag-Along Transaction, including, without limitation, any anticipated tax
benefit, synergies or other projected economic benefits, as confirmed by an
independent investment bank reasonably satisfactory to the Drag-Along Initiator
and the Company.

                  (b) The provisions of this Section 8 shall not apply to (i)
any Transfer prior to the date two years after the date hereof, (ii) any Public
Sale or (iii) any Transfer by the Drag-Along Initiator to an Affiliate of the
Drag-Along Initiator.

                  Section 9.   Issuance Rights. The Company shall not issue,
sell or exchange, or agree to issue, sell or exchange (collectively, "Issue,"
and any issuance, sale or exchange resulting therefrom, an "Issuance") any
shares of Stock (other than Excluded Securities), except as authorized by the
Board and in accordance with the following procedures:

                  (a) The Company shall deliver to Beacon a written notice (an
"Issuance Notice") that shall (i) state the Company's intention to Issue Stock
to one or more Persons, the amount and type of Stock to be Issued (the "Issuance
Stock"), the purchase price therefor and a summary of the other material terms
of the proposed Issuance and (ii) offer Beacon the option to acquire all or any
part of the Issuance Stock (the "Issuance Offer"). The Issuance Offer shall
remain open and irrevocable for the periods set forth below (and, to the extent
the Issuance Offer is accepted during such periods, until the consummation of
the Issuance contemplated by the Issuance Offer). Beacon shall have the right
and option, for a period of 30 days after delivery of the Issuance Notice (the
"Issuance Acceptance Period"), to accept all or any part of the Issuance Stock
at the purchase price and on the terms stated in the Issuance Notice. Such
acceptance shall be made by delivering a written notice to the Company by Beacon
within the Issuance Acceptance Period specifying the maximum number of shares of
the Issuance Stock that Beacon will purchase.

                  (b) If effective acceptance shall not be received pursuant to
Section 9(a) above with respect to all of the Issuance Stock offered for sale
pursuant to the Issuance Notice, then the Company may Issue all or any portion
of such Stock so offered for sale and not so accepted, at a price not less than
the price, and on terms not more favorable to the purchaser thereof than the
terms, stated in the Issuance Notice at any time within 90 days after the
expiration of the Issuance Acceptance Period (the "Issuance Period"). In the
event that all of the Issuance Stock is not Issued by the Company during the
Issuance Period, the right of the Company to Issue such unsold Issuance Stock
shall expire and the obligations of this Section 9 shall be reinstated.

                  (c) All sales of Issuance Stock to Beacon subject to any
Issuance Notice shall be consummated contemporaneously at the offices of the
Company on the later of (i) a mutually satisfactory business day within 20 days
after the expiration of the Issuance Acceptance Period or (ii) the fifth
business day following the expiration or termination of all waiting periods
under the HSR Act, applicable to such Issuance, or at such other time and/or
place as the Company and Beacon may agree. The delivery of certificates or other
instruments evidencing such Issuance Stock shall be made by the Company on such
date against payment of the purchase price for such Issuance Stock.

                  (d) The provisions of this Section 9 shall not apply to (i)
any Excluded Securities, (ii) any Issuance by the Company in connection with an
IPO or any subsequent registered public offering of Stock, (iii) any conversion
of Preferred Stock to Common Stock pursuant to the terms of the Restated
Articles or (iv) issuance by the Company to physicians in connection with an
acquisition approved by the Board or Executive Committee.

                  Section 10. Holdback Agreement; Adjustments.

                  (a) Each Shareholder agrees that, to the extent requested in
writing by a managing underwriter of an IPO or any underwritten public offering
effected by the Company within three years after an IPO, it will not Transfer
any Stock or any other equity security of the Company or any security
convertible into or exchangeable or exercisable for any equity security of the
Company (other than as part of such underwritten public offering) during the
time period reasonably requested by the managing underwriter.

                   (b) The Company shall take all reasonable steps necessary to
effect a subdivision of shares if, with respect to any demand registration
request under the Beacon Registration Agreement or the GHV Registration
Agreement, in the reasonable judgment of the managing underwriter for the
offering in respect of such demand registration, such subdivision would enhance
the marketability of the securities proposed to be registered thereunder. Each
Shareholder agrees to vote all of its shares of Stock in a manner, and to take
all other actions necessary, to permit the Company, to carry out the intent of
the preceding sentence including, without limitation, voting in favor of an
amendment to the Restated Articles in order to increase the number of authorized
shares of capital stock of the Company.

         securities are free and clear of any liens, encumbrances, rights of
         first refusal or other rights of third parties of any nature with
         respect thereto.

                         (ii) Except as set forth on Schedule 14(b) hereto and
         other than this Agreement, it is not a party to any contract or

         (y) otherwise with or relating to the Company, except for employment
         agreements entered into in the ordinary course of business.

                        (iii) In the event a Transaction (as defined in the
         Restated Articles) is approved by Beacon, the holders of the Preferred
         Stock agree that they shall, if requested by Beacon, exercise their
         right to convert all of their shares of Preferred Stock to Common Stock
         in connection with such Transaction.

                  Duration of Agreement. The rights and obligations of a
Shareholder under this Agreement shall terminate at such time as such
Shareholder no longer is the beneficial owner of any shares of Stock. This
Agreement shall terminate upon the consummation of a Qualified IPO, except that
the provisions of Sections 3.1(b) through 3.11, 10, 11.3 and 16 through 27 shall
survive until, by their respective terms, they are no longer operative.

                  Section 16. Further Assurances. At any time or from time to
time after the date hereof, the parties agree to cooperate with each other, and
at the request of any other party, to execute and deliver any further
instruments or documents and to take all such further action as the other party
may reasonably request in order to evidence or effectuate the consummation of
the transactions contemplated hereby and to otherwise carry out the intent of
the parties hereunder. Each Shareholder who is a natural Person 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 actions consistent with the
intent and purposes of this Agreement.

                  Section 17. Amendment and Waiver. Except as otherwise provided
herein, no modification, amendment or waiver of any provision of this Agreement
shall be effective against the Company or any Shareholder unless such
modification, amendment or waiver is approved in writing by the Company,
Shareholders holding at least a majority of the Shares of Common Stock, and by
Beacon so long as Beacon and its Affiliates, collectively, hold, directly and
indirectly, at least the Pre-IPO Threshold. Notwithstanding the foregoing, any
amendment to Sections 4 or 6 hereof shall require approval in writing by the
Company, Shareholders holding at least 66-2/3% of the outstanding Common Stock,
and Beacon. The failure of any party to enforce any of the provisions of this
Agreement shall in no way be construed as a waiver of such provisions and shall
not affect the right of such party thereafter to enforce each and every
provision of this Agreement in accordance with its terms.

                  Section 18.  Severability. Whenever possible, each provision
of this Agreement shall be interpreted in such manner as to be effective and
valid under applicable law, but if any provision of this Agreement is held to be
invalid, illegal or unenforceable in any respect under any applicable law or
rule in any jurisdiction, such invalidity, illegality or unenforceability shall
not affect any other provision or any other jurisdiction, but this Agreement
shall be reformed, construed and enforced in such jurisdiction as if such
invalid, illegal or unenforceable provision had never been contained herein.

                  Section 19.  Entire Agreement. Except as otherwise expressly
set forth herein, this document and the other documents dated the date hereof
embodies the complete agreement and understanding among the parties hereto with
respect to the subject matter hereof and supersedes and preempts any prior
understandings, agreements or representations by or among the parties, written
or oral, that may have related to the subject matter hereof in any way. Without
limiting the generality of the foregoing, to the extent that any of the terms
hereof are inconsistent with the rights or obligations of any Shareholder under
any other agreement with the Company, the terms of this Agreement shall govern.

                  Section 20. Successors and Assigns. Except as otherwise
provided herein, this Agreement shall bind and inure to the benefit of and be
enforceable by the Company and its successors and assigns and each Shareholder
and their respective successors, assigns, heirs and personal representatives, so
long as they hold Stock. The personal representative of a deceased Shareholder
shall automatically be subject to the terms and conditions of this Agreement.
Each Management Shareholder 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 Shareholders or the obligations of their
personal representatives, heirs, descendants, or estates, as provided in this
Agreement.

                  Section 21.  Counterparts. This Agreement may be executed in
separate counterparts each of which shall be an original and all of which taken
together shall constitute one and the same agreement.

                  Section 22. Remedies. Each Shareholder shall be entitled to
enforce its rights under this Agreement specifically to recover damages by
reason of any breach of any provision of this Agreement and to exercise all
other rights existing in their favor. The parties hereto agree and acknowledge
that money damages may not be an adequate remedy for any breach of the
provisions of this Agreement and that each party may in its sole discretion
apply to any court of law or equity of competent jurisdiction for specific
performance and/or injunctive relief (without posting a bond or other security)
in order to enforce or prevent any violation of the provisions of this
Agreement.

                  Section 23. Notices. Any notice provided for in this Agreement
shall be in writing and shall be either personally delivered, or mailed first
