                             STOCKHOLDERS AGREEMENT

                  STOCKHOLDERS AGREEMENT dated as of August 31, 1999, by and
among QUORUM HEALTH GROUP, INC., a Delaware corporation (the "Company"), WELSH,
CARSON, ANDERSON & STOWE VIII, L.P. ("WCAS VIII") and the several other persons
named in Schedule I hereto (collectively with WCAS VIII, the "Stockholders").

                  WHEREAS, the Company and the Stockholders have entered into a
Securities Purchase Agreement dated as of August 18, 1999 (the "WCAS Purchase
Agreement"), pursuant to which and on the terms and subject to the conditions
set forth therein, such Stockholders shall purchase $150,000,000 aggregate
principal amount of the Company's 6% Convertible Subordinated Debentures due
August 31, 2009 ("Debentures"), which are convertible under certain
circumstances into shares (the "Conversion Shares") of Common Stock, $.01 par
value ("Common Stock"), of the Company; and

                  WHEREAS, the Company and each of the Stockholders desire to
make certain arrangements among themselves with respect to the matters set forth
herein;

                  NOW, THEREFORE, in consideration of the premises and of the
mutual covenants and agreements herein contained, the parties hereto hereby
agree as follows:

                  Section 1. Voting Agreement. During the term of this
Agreement, at each annual or special stockholders' meeting, and whenever the
stockholders of the Company act by written consent with respect to the election
of directors, each Stockholder, severally and not jointly, agrees to vote or
otherwise give such Stockholder's consent in respect of all shares of capital
stock of the Company (whether now or hereafter acquired) owned by such
Stockholder as follows:

                  (a) for the election to the Company's Board of Directors of
         the candidates nominated by the Company's Board of Directors at such
         meeting, if any, each to serve in accordance with the provisions of the
         Company's Bylaws and applicable corporate law until his or her
         successor shall have been elected and shall have qualified, and

                  (b) as directed by the Company's Board of Directors with
         respect to any proposed transaction that would constitute a Change of
         Control (as hereinafter defined) of the Company.

                  For purposes of this Section 1, "Change of Control" means (i)
the sale, lease or transfer, whether direct or indirect (other than by way of
merger or consolidation), of all or substantially all of the assets of the
Company and its subsidiaries, taken as a whole, in one transaction or a series
of related transactions, to any "person" or "group," (ii) the liquidation or
dissolution of the Company or the adoption of a plan of liquidation or
dissolution of the Company, (iii) the acquisition of "beneficial ownership" by
any "person" or "group" of securities

<PAGE>   2

of the Company which when aggregated with all other securities of the Company
then owned by such person or group would permit such person or group to elect a
majority of the directors of the Company or any successor entity (such
securities entitled to so vote being referred to as "Voting Stock") by way of
sale, transfer or issuance of, or a series of sales, transfers and/or issuances
of, Voting Stock or otherwise, or (iv) any merger or consolidation to which the
Company is a party, except for a merger or consolidation in which the holders of
the Company's outstanding Voting Stock entitled to elect a majority of the
members of the Company's Board of Directors immediately prior to the merger or
consolidation shall continue to own directly or beneficially the outstanding
Voting Stock of the surviving corporation entitled to elect a majority of the
Board of Directors of the surviving corporation after giving effect to the
merger or consolidation.

                  For purposes of this Agreement, (i) the terms "person" and
"group" shall have the meanings set forth in Section 13(d)(3) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), whether or not
applicable, and (ii) the term "beneficial owner" shall have the meaning set
forth in Rules 13d-3 and 13d-5 under the Exchange Act, whether or not
applicable.

                  Section 2. Transfer Restrictions. Each of the Stockholders
hereby covenants and agrees, severally and not jointly, that, (i) during the
term of this Agreement, with respect to the Debentures, and (ii) during a period
of two years from the date hereof, with respect to the Conversion Shares, it
will not, directly or indirectly, offer, transfer, sell, assign, pledge,
hypothecate or otherwise dispose of (any such act being referred to herein as a
"transfer") any of the Debentures or Conversion Shares, other than (x) a
transfer to any other Stockholder, (y) a transfer by a Stockholder to his or her
spouse or lineal descendants, or any trust or other entity owned by or for the
benefit of any such person, or (z) a transfer pursuant to a transaction that
would constitute a Change of Control that is approved by the Board of Directors
of the Company as provided in Section 1(b) above. Thereafter, each Stockholder
hereby covenants and agrees, severally and not jointly, that it will not,
directly or indirectly, transfer any of the Debentures or Conversion Shares,
other than (i) in the case of WCAS VIII, to its partners, (ii) in compliance
with Rule 144 of the Exchange Act, (iii) pursuant to the Registration Rights
Agreement entered into in connection with the WCAS Purchase Agreement, or (iv)
as permitted by clauses (x), (y) or (z) of the immediately preceding sentence.
Any such transferee pursuant to clause (y) of the first sentence of this Section
2 and clause (i) of the second sentence of this Section 2 shall agree in writing
with the parties hereto to be bound by, and to comply with, all applicable
provisions of this Agreement and to be deemed to be a Stockholder for purposes
of this Agreement.

                  Section 3. Limitation on Beneficial Ownership. Each of the
Stockholders hereby covenants and agrees, severally and not jointly, that
without the prior approval of the Company's Board of Directors (it being
understood that no director who is an affiliate of any of the Stockholders shall
participate in granting such approval) for the term of this Agreement, it shall
not purchase or otherwise acquire shares of Common Stock or other securities
convertible into, or exercisable or exchangeable for, Common Stock, which
shares, when aggregated with all shares of Common Stock beneficially owned by
the Stockholders immediately prior to such transaction, would constitute greater
than 30% of the outstanding shares of Common Stock on a fully-diluted basis.

                  Section 4. Certain Other Limitations. Each of the Stockholders
hereby covenants and agrees, severally and not jointly, that during the term of
this Agreement it will not, without the prior approval of the Board of Directors
of the Company (it being understood that no director that is an affiliate of any
of the Stockholders shall participate in granting such approval), either alone
or as part of a group:

                  (a) make, or in any way participate, directly or indirectly,

         in Regulation 14A under the Exchange Act) or become a "participant" in
         any "election contest" (as such terms are defined or used in Rule
         14a-11 under the Exchange Act) to vote, or seek to advise or influence
         any person or entity with respect to the voting of, any voting
         securities of the Company or any of its affiliates;

                  (b) initiate or propose any stockholder proposals for

         stockholder meeting or by written consent, with respect to the Company
         or any of its affiliates, or propose any person for election to the
         Board of Directors of the Company or any of its affiliates, or propose
         the removal of any member of the Board of Directors of the Company or
         any of its affiliates;

                  (c) make any offer or proposal to the Board of Directors of
         the Company or publicly announce any offer or proposal (or publicly
         announce its interest in making any such offer or proposal) to enter
         into any transaction of merger, consolidation, sale of substantial
         assets or any other business combination involving the Company or any
         of its affiliates, whether or not any parties other than the
         Stockholders and their affiliates are involved (it being understood
         that this clause (c) shall not apply if a third party not acting in
         concert with any of the Stockholders or their affiliates publicly
         announces any offer or proposal (or publicly announces its interest in
         making any such offer or proposal) to enter into any such transaction,
         sale or combination); or

                  (d) form, join or in any way participate in a group to take
         any actions otherwise prohibited by the terms of this Agreement.
