                         EXECUTIVE STOCK PURCHASE PLAN

1.  Purpose of the Plan

     The purpose of the Triad Hospitals, Inc. Executive Stock Purchase Plan is
to promote the interests of the Corporation and its shareholders by
strengthening the Corporation's ability to attract, motivate, and retain key
executives upon whose judgment, initiative, and efforts the financial success
and growth of the business of the Corporation largely depend, to offer such
personnel additional incentives to put forth maximum efforts for the success of
the business, and to afford them an opportunity to acquire a proprietary
interest in the Corporation through stock ownership.

2.  Definitions

     Wherever the following capitalized terms are used in this Plan, they shall
have the meanings specified below:

     (a)  "Accrued Interest" means, with respect to any Share Purchase Loan, the
accrued interest on the unpaid balance thereof for the period from the Share
Purchase Date to the Repayment Date (as defined in Section 6.3), determined
using an interest rate equal to the applicable Federal rate in effect, under
section 1274(d) of the Code, as of the date upon which the Share Purchase Loan
is made, compounded semi-annually.

     (b)  "Board" means the Board of Directors of the Corporation.

     (c)  "Cause" means (i) the conviction of the Participant of a felony under
the laws of the United States or any state thereof, whether or not appeal is
taken, as determined by the Board in good faith; (ii) the conviction of the
Participant for a violation of criminal law involving the Corporation and its
business that materially damages the Corporation as determined by the Board in
good faith; (iii) the willful misconduct of the Participant, or the willful or
continued failure by the Participant (except in the case of a Disability) to
substantially perform his duties hereunder, in either case which has a material
adverse effect on the Corporation as determined by the Board in good faith; (iv)
the willful fraud or material dishonesty of the Participant in connection with
his performance of his duties to the Corporation and involving the finances of
the Corporation as determined by the Board in good faith; (v) Participant's
repeated use of alcohol in a manner which in the opinion of the Board materially
impairs the ability of the Participant to effectively perform the Participant's
duties and obligations owed to the Corporation, or the illegal use, possession,
or sale of, or impaired performance due to the illegal use of, controlled
substances; or (vi) a violation of the Corporation's policies on sexual or other
illegal harassment of a Corporation employee by the Participant as determined by
the Board in good faith; provided, however, in no event shall the Participant's
                         --------  -------
employment be considered to have been terminated

                                       1
<PAGE>

for "Cause" unless and until the Participant receives written notice from the
Corporation stating the acts or omissions constituting Cause and the Participant
has the opportunity to cure to the Corporation's satisfaction any such acts or
omissions (in the case of (iii), (v) or (vi) above) within 30 days of the
Participant's receipt of such notice.

     (d)  "Change in Control" means any of the following events following the
date on which the Corporation becomes a publicly-held Corporation:

               (i)  An acquisition (other than directly from the Corporation) of
                    any voting securities of the Corporation (the "Voting
                    Securities") by any "Person" (as the term Person is used for
                    purposes of Section 13(d) or 14(d) of the Securities
                    Exchange Act of 1934, as amended (the "1934 Act"))
                    immediately after which such Person has "Beneficial
                    Ownership" (within the meaning of Rule 13d-3 promulgated
                    under the 1934 Act) of twenty percent (20%) or more of the
                    combined voting power of the then outstanding Voting
                    Securities; provided, however, that in determining whether a
                                --------  -------
                    Change in Control has occurred, Voting Securities which are
                    acquired in a "Non-Control Acquisition" (as hereinafter
                    defined) shall not constitute an acquisition which would
                    cause a Change in Control.  A "Non-Control Acquisition"
                    shall mean an acquisition by (i) an employee benefit plan
                    (or a trust forming a part thereof) maintained by (A) the
                    Corporation or (B) any Corporation or other Person of which
                    a majority of the voting power or the equity securities or
                    equity interests is owned directly or indirectly by the
                    Corporation (a "Control Subsidiary"), or (ii) the
                    Corporation or any Control Subsidiary.

               (ii) The individuals who, as of the date the Corporation issues
                    any class of equity securities required to be registered
                    under Section 12 of the 1934 Act,  are members of the Board
                    (the "Incumbent Board"), cease for any reason to constitute
                    at least two-thirds of the Board; provided, however, that if
                                                      --------  -------
                    the election or nomination for election by the Corporation's
                    stockholders of any new director was approved by a vote of
                    at least two-thirds of the Incumbent Board, such new
                    director shall, for purposes of this Stock Purchase
                    Agreement, be considered as a member of the Incumbent Board;
                    provided, further, however, that no individual shall be
                    --------  -------  -------
                    considered a member of the Incumbent Board if (1) such
                    individual initially assumed office as a result of either an
                    actual or threatened "Election Contest" (as described in
                    Rule 14a-11 promulgated under the

                                       2
<PAGE>

                    934 Act) or other actual or threatened solicitation of
                    proxies or consents by or on behalf of a Person other than
                    the Board (a "Proxy Contest") including by reason of any
                    Stock Purchase Agreement intended to avoid or settle any
                    Election Contest or Proxy Contest or (2) such individual was
                    designated by a Person who has entered into an Stock
                    Purchase Agreement with the Corporation to effect a
                    transaction described in clause (i) or (iii) of this Section
                    2(d); or

              (iii) Consummation, after approval by stockholders of the
                    Corporation, of:


                    (1)  A merger, consolidation or reorganization involving the
                         Corporation, unless,

                         (A)  The stockholders of the Corporation, immediately
                         before such merger, consolidation or reorganization,
                         own, directly or indirectly immediately following such
                         merger, consolidation or reorganization, at least
                         seventy-five percent (75%) of the combined voting power
                         of the outstanding Voting Securities of the Corporation
                         resulting from such merger or consolidation or
                         reorganization or its parent Corporation (the
                         "Surviving Corporation") in substantially the same
                         proportion as their ownership of the Voting Securities
                         immediately before such merger, consolidation or
                         reorganization;

                         (B)  The individuals who were members of the Incumbent
                         Board immediately prior to the execution of the Stock
                         Purchase Agreement providing for such merger,
                         consolidation or reorganization constitute at least
                         two-thirds of the members of the board of directors of
                         the Surviving Corporation; and


                         (C)  No Person (other than the Corporation, any Control
                         Subsidiary, any employee benefit plan (or any trust
                         forming a part thereof) maintained by the Corporation,
                         the Surviving Corporation or any Control Subsidiary, or
                         any Person who, immediately prior to such merger,
                         consolidation or reorganization, had Beneficial
                         Ownership of twenty percent (20%) or more of the then
                         outstanding Voting Securities) has Beneficial Ownership
                         of twenty

                                       3
<PAGE>

                         percent (20%) or more of the combined voting power of
                         the Surviving Corporation's then outstanding Voting
                         Securities.

                    (2)  A complete liquidation or dissolution of the
                         Corporation; or

                    (3)  The sale or other disposition of all or substantially
                         all of the assets of the Corporation to any Person
                         (other than a transfer to a Control Subsidiary).

     Notwithstanding the foregoing, a Change in Control shall not be deemed to
occur solely because any Person (the "Subject Person") acquired Beneficial
Ownership of more than the permitted amount of the outstanding Voting Securities
as a result of the acquisition of Voting Securities by the Corporation which, by
reducing the number of Voting Securities outstanding, increased the proportional
number of shares Beneficially Owned by the Subject Person, provided that if a
Change in Control would occur (but for the operation of this sentence) as a
result of the acquisition of Voting Securities by the Corporation, and after
such share acquisition by the Corporation, the Subject Person becomes the
Beneficial Owner of any additional Voting Securities which increases the
percentage of the then outstanding Voting Securities Beneficially Owned by the
Subject Person, then a Change in Control shall occur.

     (e)  "Code" means the Internal Revenue Code of 1986, as amended.

     (f)  "Committee" means the compensation committee appointed to administer
the Plan and shall consist of two or more directors of the Corporation, (i) none

requirements of a "non-employee director" within the meaning of Rule 16b-3 of
the Securities Exchange Act of 1934. The members of the Committee shall be
appointed by, and serve at the pleasure of, the Board.

faith determine the Fair Market Value in whatever manner it considers
appropriate.

Participant's reporting responsibilities, or any action by the Corporation or a
Subsidiary that results in a diminution in such position, authority, duties or
responsibilities, but excluding for these purposes an isolated and insubstantial
action not taken in bad faith and which is remedied by the Corporation or
Subsidiary (as the case may be) promptly after receipt of written notice thereof
by the Participant, (2) the relocation, without the consent of the Participant,
of the Corporation's principal executive offices or the office of the

               ----------------
Section, the aggregate number of Shares that may be purchased pursuant to all
Rights granted under the Plan is 1,000,000 Shares. The Shares to be delivered
under the Plan shall be made available from authorized but unissued Shares or
issued Shares that have been reacquired by the Corporation. To the extent that
any Right is forfeited, cancelled, or otherwise terminated without the issuance
of all Shares covered thereunder, such Shares shall no longer be charged against
the foregoing maximum Share limitation and may again be made subject to Rights
under the Plan pursuant to such limitation.

                                       6

          3.2. Adjustments. If there shall occur any recapitalization,
               -----------
reclassification, stock dividend, stock split, reverse stock split, or other
distribution with respect to Shares, or other change in corporate structure
affecting the Shares, the Committee may, in the manner and to the extent that it
deems appropriate and equitable to the Participants and consistent with the
terms of this Plan, cause an adjustment to be made in: (i) the maximum number
and kind of Shares provided in Section 3.1 hereof, (ii) the number and kind of
Shares subject to then outstanding Rights, or (iii) any other terms of a Right
that are affected by the event.

4.   Administration of the Plan

          4.1. Committee Members.  The Plan shall be administered by the
               -----------------
Committee. The Committee shall have such powers and authority as may be
necessary or appropriate for the Committee to carry out its functions as
described in the Plan. No member of the Committee shall be liable for any action
or determination made in good faith by the Committee with respect to the Plan or
any Right thereunder.

          4.2. Discretionary Authority.  Subject to the express provisions of
               -----------------------
the Plan, including the provisions of Section 5.1, the Committee shall have
authority in its discretion to determine the Eligible Persons to whom, and the
time or times at which, Rights are granted, the number of Shares that may be
purchased under a Right, the date or period during which a Right may be
exercised and all other terms of a Right. The Committee shall also have
discretionary authority to interpret the Plan, to make all factual
determinations under the Plan, and to make all other determinations necessary or
advisable for Plan administration. The Committee may prescribe, amend, and
rescind rules and regulations relating to the Plan. All interpretations,
determinations, and actions by the Committee shall be final, conclusive, and
binding upon all parties.

          4.3. Changes to Rights. The Committee shall have the authority to
               -----------------
effect, at any time and from time to time, (i) the cancellation of any or all
outstanding Rights and the grant in substitution therefor of new Rights covering
the same or different numbers of Shares, or (ii) the amendment of the terms of
any and all outstanding Rights; provided, however, that no such action by the
                                --------  -------
Committee may adversely impair the rights of a Participant under any outstanding
Right without the consent of the Participant.

5.   Grant and Exercise of Rights

          5.1. Grant of Rights. Any Eligible Person may be designated by the
               ---------------
Committee, in its sole discretion, to receive a Right under the Plan.
Notwithstanding the foregoing, the initial Eligible Persons shall be as listed
in Appendix A and each such individual's Right shall cover the number of whole
Shares that can be purchased with the dollar amount listed for the individual on

                                       7
<PAGE>

Appendix A (based on the Fair Market Value of a Share on the Share Purchase
Date); provided, however, that such number of Shares shall in no event exceed
       --------  -------
the number of Shares that could be purchased with such dollar amount if the
applicable Fair Market Value of a Share were $12.50; and, provided, further,
                                                          --------  -------
that no person may be granted more than one Right under the Plan, except that if
the Right of any initial Eligible Person to purchase Shares shall be limited
under the next preceding proviso (because the Fair Market Value of a Share is
below $12.50) and Shares remain available for issuance under the Plan at the
close of the exercise period for initial Eligible Persons under Section 5.2, the
Committee may, in its discretion, issue an additional Right to any such initial
Eligible Person thus affected by the next preceding proviso. Each Right shall be
evidenced by a Stock Purchase Agreement between the Corporation and the
Participant.

     5.2. Exercise of Rights. A Right granted to a Participant may be exercised,
          ------------------
in whole or in part, by written notice to the Corporation on or prior to (a) the
exercise date selected in the notice in accordance with the terms of such Right,
or (b) the date specified in the related Stock Purchase Agreement as the
permissible exercise date; provided, however, that if a Right shall be thus
                           --------  -------
exercised by a Participant as to only a portion of the Shares covered thereby,
such Right shall thereupon terminate and shall not be exercisable with respect
to any additional Shares; and provided, further, that a Right may be exercised
                              --------  -------
by a Participant only if he is an Employee of the Corporation or a Subsidiary on
the exercise date and shall terminate in its entirety upon a Participant's
termination of employment. Notwithstanding the foregoing, in the case of an
initial Eligible Person receiving a Right in accordance with Appendix A, such
Right may be exercised on the date elected by such Participant during the period
which starts on the date the Corporation's Shares are distributed to
Columbia/HCA Healthcare Corporation stockholders and ends on the twenty-first
trading day for the Corporation's Shares. Any Participant giving such a notice
of exercise shall be considered to have agreed to pay the full Share Purchase
Price through a Share Purchase Loan, except to the extent the notice is
accompanied by a cash payment.

6.   Share Purchase Loan

     6.1. Loan Amount. The Corporation shall loan each Participant 100% of the
          -----------
Share Purchase Price of any Purchased Shares acquired by the Participant, on a
full recourse basis, to the extent the Participant shall not elect to pay such
Share Purchase Price in cash and contingent upon the Participant's executing
such promissory note and pledge documents relating to the security interest
described in Section 7.1 below as the Corporation shall reasonably require.

     6.2. Interest Rate. Accrued Interest under any Share Purchase Loan will be
          -------------
payable only upon maturity or upon prepayment of such Share Purchase Loan.

     6.3. Maturity and Repayment.
          ----------------------

                                       8
<PAGE>

     (a)  Repayment at Maturity. A Share Purchase Loan will mature upon the
earlier of (i) the fifth anniversary of such Share Purchase Loan's Share
Purchase Date, (ii) termination of the Participant's employment for any reason,
or (iii) bankruptcy of the Participant (the "Repayment Date"). Within 120 days
following the Repayment Date, the Participant shall be required to pay the
Corporation the full amount remaining due on such Share Purchase Loan, including
all unpaid Accrued Interest.

     (b)  Payment of Additional Interest. In the event a Participant's
employment terminates for Cause or the Participant voluntarily terminates
employment (other than for Good Reason) prior to the third anniversary of a
Share Purchase Loan's Share Purchase Date, or if earlier, the date of a Change
in Control, in addition to any amounts due in repayment of the amount of such
Share Purchase Loan and Accrued Interest, the Participant shall pay the
Corporation an amount equal to the additional interest that would have been
payable in respect of such Share Purchase Loan, if the regular interest rate on
such loan had been the prime rate (as reported in the Two Star Edition of The
Wall St. Journal in effect on the Share Purchase Date), and interest on such
additional interest at such rate to the actual date of payment.

     6.4. Prepayments.
          -----------

     (a)  Mandatory Prepayments. Any cash dividends received on Purchased Shares
prior to payment of the full amount due on a Share Purchase Loan (including
Accrued Interest), net of assumed Federal, State and Local income taxes (as
reasonably determined by the Participant based upon the highest marginal tax
rates then applicable income tax laws to which the Participant is subject),
shall be used to prepay such Share Purchase Loan. Prepayments shall be applied
first to Accrued Interest, then to principal.

     (b)  Voluntary Prepayments. A Share Purchase Loan may be prepaid, in whole
or in part, at any time. Prepayments shall be applied first to Accrued Interest,
then to principal. Notwithstanding the provisions of Section 7.2, at any time
following the earlier of (i) the second anniversary of a Share Purchase Loan's
Share Purchase Date, or (ii) upon a Change in Control, the Purchased Shares may,
at the Participant's election, be sold to prepay the loan, in whole or in part,
in addition to any transaction costs incurred by the Participant' to effect such
sale and all taxes resulting with respect to such sale (as reasonably determined
by the Participant based upon the highest marginal tax rates then applicable
income tax laws to which the Participant is subject).

7.   Shareholder Rights.

     7.1. Security Interest. A Share Purchase Loan shall be secured by the
          -----------------
related Purchased Shares. At the time the Participant purchases Purchased Shares
hereunder, a certificate representing such Purchased Shares shall be registered
in the name of the Participant. Such certificate shall be held by the
Corporation (or any custodian appointed by the Corporation) for the account of
the Participant, subject to the terms and conditions hereof, and shall bear a
legend setting forth the restrictions imposed thereon hereunder, in such form as
the Corporation, in its discretion, may determine.

     7.2. Transfer Restrictions. The Participant shall have all rights of a
          ---------------------
stockholder with respect to Purchased Shares, including the right to receive
dividends (subject to the provisions of Section 6.4(a)) and the right to vote
such Purchased Shares, except that the Participant shall not be entitled to
delivery of the stock certificates representing Purchased Shares and no
Purchased Shares may be sold, assigned, transferred, pledged, hypothecated or
otherwise encumbered or disposed of (except by will or the applicable laws of
descent and distribution) until the later of (i) full repayment of the Share
Purchase Price for such Purchased Shares and any related Accrued Interest (and
any additional amount due under Section 6.3 ), and (ii) the earliest of (1) the
third anniversary of the Share Purchase Date for such Purchased Shares, (2) the
Participant's termination of employment or bankruptcy and (3) a Change in
Control. Notwithstanding the foregoing, Purchased Shares may be sold to pay the
related Share Purchase Loan (including Accrued Interest) at maturity or (to the
extent provided in Section 6.4(b)) to voluntarily prepay such Share Purchase
Loan (including Accrued Interest). Any Shares, any other securities of the
Corporation and any other property (except cash dividends) distributed with
respect to Purchased Shares shall be subject to the same restrictions, terms and
conditions as such Purchased Shares.

     7.3. Section 83(b) Election. The Committee may provide in a Stock Purchase
          ----------------------
Agreement that the Participant's rights with respect to the Purchased Shares are
conditioned upon the Participant's refraining from making an election with
respect to the related Right under section 83(b) of the Code. If a Right is not
so conditioned and a Participant makes an election pursuant to section 83(b) of
the Code with respect to the Purchased Shares, the Participant shall be required
to promptly file a copy of such election with the Corporation.

     7.4. Death or Disability Benefit. In the event a Participant terminates
          ---------------------------
employment because of death or Disability, if the amount remaining due on a
Share Purchase Loan (including Accrued Interest) is greater than the Fair Market
Value of the related Purchased Shares as of the date of such death or
Disability, the Corporation shall pay a death or Disability benefit equal to

                                      10
<PAGE>

(1) the amount of such payment remaining due over (2) such Purchased Shares'
Fair Market Value as of the date of such death or Disability.

8.   General Provisions

          8.1. No Assignment or Transfer. Rights under the Plan shall not be
               -------------------------
assignable or transferable and shall be exercised only by the Participant.

          8.2. Rights as Shareholder. A Participant shall have no rights as a
               ---------------------
holder of Shares, with respect to any unissued Shares covered by a Right, until
the date the Participant becomes the holder of record of such Shares.

          8.3. Employment or Service. Nothing in the Plan, in the grant of any
               ---------------------
Right or in any Stock Purchase Agreement shall confer upon any Eligible Person
the right to continue in the capacity in which he is employed by, or otherwise
serves, the Corporation or any Subsidiary.

          8.4. Securities Laws. No Shares shall be issued or transferred
               ---------------
pursuant to a Right unless and until all then-applicable requirements imposed by
federal and state securities and other laws, rules and regulations and by any
regulatory agencies having jurisdiction, and by any stock exchanges upon which
the Shares may be listed, have been fully met. As a condition precedent to the
issuance of Shares pursuant to the exercise of a Right, the Corporation may
require the Participant to take any reasonable action to meet such requirements.
The Committee may impose such conditions on any Shares issuable under the Plan
as it may deem advisable, including, without limitation, restrictions designed
to satisfy the requirements of the Securities Act of 1933, as amended, the
requirements of any stock exchange upon which such Shares of the same class are
then listed, and the requirements of any blue sky or other securities laws
applicable to such Shares.

          8.5. Unfunded Plan. The adoption of this Plan and any setting aside
               -------------
of cash amounts or Shares by the Corporation with which to discharge its
obligations hereunder shall not be deemed to create a trust or other funded
arrangement. The Corporation's obligations under this Plan shall represent
general, unsecured obligations of the Corporation payable solely from the
general assets of the Corporation, and a Participant shall have no interest in
any assets of the Corporation by virtue of this Plan, except as a general
unsecured creditor of the Corporation.

          8.6. Compensation and Benefit Plans. The adoption of the Plan shall
               ------------------------------
not affect any stock incentive or other compensation plans in effect for the
Corporation or any Subsidiary, nor shall the Plan preclude the Corporation from
establishing any form of stock incentive or other compensation for employees of
the Corporation or any Subsidiary.

                                      11
<PAGE>

          8.7.  Plan Binding on Transferees. The Plan shall be binding upon the
                ---------------------------
Corporation, its transferees and assigns, and each Participant, his executor or
administrator and beneficiaries. In the event a Participant's legal
representative or legatee succeeds to his interests under the Plan, all
references to the Participant shall be considered to refer to the applicable
successor in interest (unless the context clearly indicates otherwise).

          8.8.  Construction and Interpretation. Whenever used herein, nouns in
                -------------------------------
the singular shall include the plural, and the masculine pronoun shall include
the feminine gender. Headings of Articles and Sections hereof are inserted for
convenience and reference and constitute no part of the Plan.

          8.9.  Severability. If any provision of the Plan or any Stock Purchase
                ------------
Agreement shall be determined to be illegal or unenforceable by any court of law
in any jurisdiction, the remaining provisions hereof and thereof shall be
severable and enforceable in accordance with their terms, and all provisions
shall remain enforceable in any other jurisdiction.

          8.10. Governing Law. The validity and construction of this Plan and of
                -------------
the Stock Purchase Agreements shall be governed by the laws of the State of
Texas.

9.   Effective Date; Shareholder Approval; Termination; Amendment

          9.1.  Effective Date. The Effective Date of the Plan shall be the date
                --------------
the Corporation's common stock is distributed to Columbia/HCA Healthcare
Corporation stockholders.

          9.2.  Shareholder Approval. The Plan shall be approved by the
                --------------------
shareholders* of the Corporation within twelve (12) months before or after
the Plan is adopted.

          9.3.  Termination. The Plan shall terminate on the date immediately
                -----------
preceding the tenth anniversary of the date the Plan is adopted by the Board.
The Board may, in its sole discretion and at any earlier date, terminate the
Plan. Notwithstanding the foregoing, no termination of the Plan shall adversely
affect any Right theretofore granted, without the consent of the Participant.

          9.4.  Amendment. The Board may at any time and from time to time, and
                ---------
in any respect, amend or modify the Plan; provided, however, that no amendment
                                          --------  -------
or modification of the Plan shall adversely affect any Right theretofore granted
without the consent of the Participant.
