pursuant to an indenture dated as of May 11, 1999 (the "Indenture") between
Healthtrust and Citibank N.A., as trustee (the "Trustee"). Securities issued in
book-entry form will be issued to Cede & Co. as nominee of The Depositary Trust

Healthtrust, the Trustee and DTC.

     Healthtrust has prepared and delivered to each Initial Purchaser copies of
a preliminary offering circular dated April 12, 1999 (the "Preliminary Offering
Circular") and has prepared and will deliver to each Purchaser, on the date
hereof or the next succeeding day, copies


of a final offering circular dated April 30, 1999 (the "Final Offering
Circular"), each for use by such Purchaser in connection with its solicitation
of purchases of, or offering of, the Securities. "Offering Circular" means, with
respect to any date or time referred to in this Agreement, the most recent
offering circular (whether the Preliminary Offering Circular or the Final
Offering Circular, or any amendment or supplement to either such document),
including annexes and exhibits thereto and any documents incorporated therein by
reference, which has been prepared and delivered by Healthtrust to the
Purchasers in connection with their solicitation of purchases of, or offering
of, the Securities.

     For purposes of this Agreement, (a) the term "Business" shall mean the net
assets, business and operations comprising the Pacific Group Division of
Columbia/HCA Healthcare Corporation ("Columbia/HCA") and (b) the term
"Distribution" shall mean (i) the incurrence by Healthtrust of the indebtedness
evidenced by the Securities and by the new credit agreement described in the
Offering Circular (the "New Credit Agreement"), (ii) the transfer of the
Business by Healthtrust to Triad Hospitals, Inc. ("Triad"), a new wholly owned
subsidiary of Healthtrust, and the simultaneous assumption by Triad of the
indebtedness evidenced by the Securities and by the New Credit Agreement, (iii)
the subsequent transfer of the Business by Triad to Triad Hospitals Holdings,
Inc. ("Holdings"), a new wholly owned subsidiary of Triad, and the simultaneous
assumption by Holdings of the indebtedness evidenced by the Securities and the
New Credit Agreement, (iv) the distribution by Healthtrust of all of the common
stock of Triad to Columbia/HCA, and (v) the distribution by Columbia/HCA of all
of the common stock of Triad to the stockholders of Columbia/HCA, in each case,

     Upon Healthtrust transferring the Business to Triad and the assumption by
Triad of the indebtedness evidenced by the Securities, Healthtrust will cause
Triad to assume all the rights, obligations and liabilities of Healthtrust under
this Agreement pursuant to the Triad Assumption Agreement, the form of which is
attached as Annex VI hereto. Upon Triad transferring the Business to Holdings
and the assumption by Holdings of the indebtedness evidenced by the Securities,
Triad will cause Holdings to assume all rights, obligations and liabilities of
Triad under this Agreement pursuant to the Holdings Assumption Agreement, the
form of which is attached as Annex VII hereto. Following the assumption by
Holdings of the indebtedness evidenced by the Securities, Holdings will
contribute certain assets to its subsidiary, Triad Holdings II, LLC and Triad
Holdings II, LLC will then contribute certain assets to its subsidiary, Triad
Holdings III, Inc. Following these contributions and immediately prior to the
completion of the Distribution, Holdings will cause the Guarantors (as defined
in the Guarantor Assumption Agreement) to execute the Guarantor Assumption
Agreement, the form of which is attached as Annex VIII hereto, pursuant to which
each Guarantor will agree to observe and perform as a "Guarantor" all rights,
obligations and liabilities of such Guarantor under this Agreement. The parties
hereto acknowledge and agree that once (i) the Business has been validly
transferred to Triad and the Triad Assumption Agreement has been executed and
delivered by the parties thereto, Healthtrust shall automatically be fully,
unconditionally and irrevocably released from all rights, obligations and
liabilities under this Agreement and (ii) the


Business has been validly transferred to Holdings and the Holdings Assumption
Agreement has been executed and delivered by the parties thereto, Triad shall
automatically be fully, unconditionally and irrevocably released from all
rights, obligations and liabilities under this Agreement. For purposes of this
Agreement, the "Company" shall refer to any of Healthtrust or Triad or Holdings,
depending on which such company has then assumed all rights, obligations and
liabilities under this Agreement as discussed in this paragraph. The holders of
the Securities will be entitled to the benefits of the exchange and registration
rights agreement substantially in the form of Annex IX hereto to be dated as of
the Time of Delivery (the "Registration Rights Agreement") among Healthtrust and
the Purchasers, pursuant to which the Company will agree to file as soon as
practicable after the Time of Delivery but in any event within 90 days after the
Time of Delivery, a registration statement with the Securities and Exchange
Commission (the "Commission") registering the Exchange Notes (as defined in the
Registration Rights Agreement) under the United States Securities Act of 1933,
as amended (the "Act").

   Healthtrust represents and warrants to, and agrees with, each of the
Purchasers as of the date hereof and as of the Time of Delivery, and agrees with
each Purchaser, that:

     (a) Offering Circular. The Offering Circular and any amendments or
     supplements thereto do not and will not, as of their respective dates and
     as of the Time of Delivery, contain an untrue statement of a material fact
     or omit to state a material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading; provided that this representation, warranty and agreement shall
     not apply to any statements or omissions from the Offering Circular made in
     reliance upon and in conformity with information furnished to the Company
     in writing by any Purchaser through Goldman, Sachs & Co. expressly for use
     in the Offering Circular.

     (b) Independent Accountants. The accountants who certified the financial
     statements and supporting schedules included in the Offering Circular are
     independent public accountants with respect to each of Triad and its
     subsidiaries and Columbia/HCA and its subsidiaries within the meaning of
     Regulation S-X under the Act.

     (c) Financial Statements. The historical financial statements relating to
     Triad, together with the related schedules and notes, included in the
     Offering Circular present fairly, in all material respects, the financial
     position of Holdings at the dates indicated and the combined statements of
     operations, combined statements of equity and combined statements of cash
     flows of Holdings for the periods specified; said financial statements have
     been prepared in conformity with generally accepted accounting principles
     ("GAAP") applied on a consistent basis throughout the periods involved
     except as disclosed therein. The selected historical financial data and the
     summary financial data



     included in the Offering Circular present fairly, in all material respects,
     the information shown therein and have been compiled on a basis consistent
     with that of the audited financial statements included in the Offering
     Circular. The pro forma financial statements of Triad and the related notes
     thereto included in the Offering Circular present fairly in all material
     respects the information shown therein, have been prepared in all material
     respects in accordance with the Commission's rules and guidelines with
     respect to pro forma financial statements and have been properly compiled
     on the bases described therein, and in the Company's opinion the
     assumptions used in the preparation thereof are reasonable and the
     adjustments used therein are appropriate to give effect to the transactions
     and circumstances referred to therein. The financial statements relating to
     Columbia/HCA, together with the related schedules and notes, included in
     the Offering Circular present fairly in all material respects the financial
     position of Columbia/HCA at the dates indicated and the consolidated
     statements of operations, consolidated statements of stockholders' equity
     and consolidated statements of cash flows of Columbia/HCA for the periods
     specified; said financial statements have been prepared in conformity with
     GAAP applied on a consistent basis throughout the periods involved except
     as disclosed therein.

     (d) No Material Adverse Change in Business. Since the respective dates as
     of which information is given in the Offering Circular, except as otherwise
     described in the Offering Circular, (i)-there has been no material adverse
     change in the condition, financial or otherwise, or in the earnings,
     business affairs or business prospects of the Business whether or not
     arising in the ordinary course of business (a "Material Adverse Effect"),
     (ii)-there have been no transactions entered into by the Business, Triad or
     Holdings or any of the Designated Subsidiaries (as defined in Section 1(f)
     hereof), other than those in the ordinary course of business, which are
     material with respect to the Business, and (iii) there has been no dividend
     or distribution of any kind declared, paid or made by any of Triad or
     Holdings on any class of its capital stock. Since the respective dates as
     of which information is given in the Offering Circular, except as otherwise
     stated therein, there has not been any material increase in the amount of
     debt to be assumed by Triad and its subsidiaries in connection with the
     Distribution. Since the respective dates as of which information is given
     in the Offering Circular, there has been no material adverse change in the
     condition, financial or otherwise, or in the earnings, business affairs or
     business prospects of Healthtrust and its subsidiaries, considered as a
     whole, which would materially adversely affect Healthtrust's ability to
     redeem the Securities if it were required to do so pursuant to the
     mandatory redemption provisions in the Indenture (a "Material Adverse
     Effect on the Mandatory Redemption").

     (e) Good Standing of Healthtrust, Triad and Holdings. Each of Healthtrust,
     Triad and Holdings has been duly organized and is validly existing as a
     corporation in good standing under the laws of the State of Delaware and
     has corporate power and authority to own, lease and operate its properties
     and to conduct its business as


     described in the Offering Circular and to enter into and perform its
     obligations under this Agreement; and each of Healthtrust, Triad and
     Holdings is duly qualified as a foreign corporation to transact business
     and is in good standing in each other jurisdiction in which such
     qualification is required, whether by reason of the ownership or leasing of
     property or the conduct of business, except where the failure so to qualify
     or to be in good standing would not result in a Material Adverse Effect.

     (f) Good Standing of Designated Subsidiaries. Each subsidiary of
     Healthtrust to be contributed to Holdings in connection with the
     Distribution (each a "Designated Subsidiary" and, collectively, the
     "Designated Subsidiaries") has been duly organized and is validly existing
     as a corporation, a limited liability company or a limited partnership in
     good standing under the laws of the jurisdiction of its incorporation or
     formation, has the requisite power and authority to own, lease and operate
     its properties and to conduct its business as described in the Offering
     Circular and is duly qualified as a foreign corporation or foreign limited
     liability company to transact business and is in good standing in each
     jurisdiction in which such qualification is required, whether by reason of
     the ownership or leasing of property or the conduct of business, except
     where the failure so to qualify or to be in good standing would not result
     in a Material Adverse Effect; except as otherwise disclosed in the Offering
     Circular, all of the issued and outstanding capital stock of each
     Designated Subsidiary has been duly authorized and validly issued, is fully
     paid and non-assessable and, with respect to shares owned by Healthtrust,
     such shares are owned by Healthtrust, directly or through subsidiaries,
     free and clear of any security interest, mortgage, pledge, lien,
     encumbrance, claim or equity other than those created pursuant to the New
     Credit Agreement; none of the outstanding shares of capital stock of the
     Designated Subsidiaries was issued in violation of any preemptive or
     similar rights of any securityholder of such Designated Subsidiary. Triad
     has no direct subsidiaries other than Holdings and Holdings has no
     subsidiaries other than Triad Holdings II, LLC and Triad Holdings III, Inc.

     (g) Capitalization. The authorized, issued and outstanding capital stock
     of Triad, after giving effect to the Distribution, will be as set forth in
     the Offering Circular in the column entitled "As Adjusted" under the
     caption "Capitalization" (except for subsequent issuances, if any, pursuant
     to this Agreement, pursuant to reservations, agreements, employee benefit
     plans referred to in the Offering Circular or pursuant to the exercise of
     convertible securities or options referred to in the Offering Circular).
     The shares of issued and outstanding capital stock of each of Healthtrust,
     Triad and Holdings have been duly authorized and validly issued and are
     fully paid and non-assessable; none of the outstanding shares of capital
     stock of Healthtrust, Triad or Holdings was issued in violation of the
     preemptive or other similar rights of any securityholder of Healthtrust,
     Triad or Holdings. Healthtrust owns 100% of the capital stock of Triad and
     Triad owns 100% of the capital stock of Holdings.

     of Triad, Holdings or any of the Designated Subsidiaries or any of


     their assets, properties or operations (including, without limitation, the
     Business), except, in each case, for such defaults or violations that would
     not result in a Material Adverse Effect; and the execution, delivery and
     performance by Triad or Holdings of this Agreement, the Indenture, the

     of Triad and Holdings with their respective obligations hereunder have been
     duly authorized by all necessary corporate action and do not and will not,
     whether with or without the giving of notice or passage of time or both,
     conflict with or constitute a breach of, or default or a Repayment Event
     (as defined below) under, or result in the creation or imposition of any
     lien, charge or encumbrance upon any property or assets of Triad, Holdings
     or any of the Designated Subsidiaries pursuant to, the Agreements and
     Instruments, except for such conflicts, breaches or defaults or liens,
     charges, encumbrances or Repayment Events that, singly or in the aggregate,
     would not result in a Material Adverse Effect or are disclosed in the
     Offering Circular, nor will such action result in any violation of the
     provisions of (A) the charter, by-laws or other formation documents of any
     of Healthtrust, Triad or Holdings or any of the Designated Subsidiaries or
     (B) any applicable law, statute, rule, regulation, judgment, order, writ or

     (including, without limitation, the Business), except, in the case of (B)
     above, for such violations that would not result in a Material Adverse
     Effect. As used herein, a "Repayment Event" means any event or condition
     which gives the holder of any note, debenture or other evidence of
     indebtedness (or any person acting on such holder's behalf) the right to
     require the repurchase, redemption or repayment of all or a portion of such
     indebtedness by any of Triad or Holdings or any of the Designated
     Subsidiaries. Healthtrust is not in violation of its Certificate of
     Incorporation or by-laws, except for such violations that would not result
     in a Material Adverse Effect on the Mandatory Redemption; and the
     execution, delivery and performance by Healthtrust of this Agreement, the

     Agreement, the Indenture, the Registration Rights Agreement and the
     Securities have been duly authorized by all necessary corporate action and

     passage of time or both, conflict with or constitute a breach of, or
     default or a Healthtrust Repayment


     Event (as defined below) under, or result in the creation or imposition of
     any lien, charge or encumbrance upon any property or assets of Healthtrust
     pursuant to any obligation, agreement, covenant or condition contained in
     any contract, indenture, mortgage, deed of trust, loan or credit agreement,
     note, lease or other agreement or instrument to which Healthtrust is a
     party or by which it is bound or to which any of its properties or assets
     is subject (collectively, the "Healthtrust Agreements and Instruments"),
     except for such conflicts, breaches or defaults or liens, charges,
     encumbrances or Healthtrust Repayment Events that, singly or in the
     aggregate, would not result in a Material Adverse Effect on the Mandatory
     Redemption or are disclosed in the Offering Circular, nor will such action
     result in any violation of the provisions of (A) the Certificate of
     Incorporation or by-laws of Healthtrust or (B) any applicable law, statute,
     rule, regulation, judgment, order, writ or decree of any government,
     government instrumentality or court, domestic of foreign, having

     (m) Absence of Labor Dispute. No labor dispute with the employees of any of
     the Business, Triad or Holdings or any of the Designated Subsidiaries
     exists or, to the knowledge of the Company, is imminent, which, would
     result in a Material Adverse Effect.

     (n) Absence of Proceedings. Except as disclosed in the Offering Circular,
     there is no action, suit, proceeding, inquiry or investigation before or
     brought by any court or governmental agency or body, domestic or foreign,

     threatened, against or affecting any of Healthtrust, Triad or Holdings or
     any of the Designated Subsidiaries which would reasonably be expected to
     result in a Material Adverse Effect, or which might reasonably be expected
     to materially and adversely affect the Business or the consummation of the
     transactions contemplated by this Agreement or the Distribution or the
     performance by the Company of its obligations hereunder or under the
     Securities or the Exchange Notes. The aggregate of all pending legal or
     governmental proceedings to which any of Healthtrust, Triad or Holdings or
     any of the Designated Subsidiaries is a party or of which any of their
     respective property or assets is the subject which are not described in the

     systems or procedures), trademarks, service marks, trade names or other

     with respect to any Intellectual Property or of any facts or circumstances
     which would render any Intellectual Property invalid or inadequate to
     protect the interest of the Business therein, and which infringement or
     conflict (if the subject of any unfavorable decision, ruling or finding) or
     invalidity or inadequacy, singly or in the aggregate, would result in a
     Material Adverse Effect.

     (p) Absence of Further Requirements. No filing with, or authorization,
     approval, consent, license, order, registration, qualification or decree
     of, any court or governmental authority or agency is necessary or required

     obligations hereunder, in connection with (i) the offering, issuance or

     contemplated by this Agreement, the Registration Rights Agreement and the
     Indenture, (iii) the consummation of the Distribution or (iv) for the due

     Indenture Act, in connection with the Exchange Offer and (E) for such
     approvals or consents the failure so to obtain with respect to Triad and
     Holdings would not have a Material Adverse Effect and would not materially
     and adversely affect the consummation of the transactions contemplated by
     this Agreement, the Registration Rights Agreement, the Indenture or the
     Distribution and, with respect to Healthtrust would not have a Material
     Adverse Effect on the Mandatory Redemption.

     Triad, Holdings and the Designated Subsidiaries possess such permits,
     licenses, approvals, consents and other authorizations (collectively,
     "Governmental Licenses") which have been issued by the appropriate federal,
     state, local or foreign regulatory agencies or bodies necessary to conduct
     the business now operated by them and to be conducted by them after giving
     effect to the Distribution, except as disclosed in the Offering Circular
     and except where the



     failure to so possess such Government Licenses would not, singly or in the
     aggregate, have a Material Adverse Effect; each of the Business, Triad,
     Holdings and the Designated Subsidiaries is in compliance with the terms
     and conditions of all such Governmental Licenses, except where the failure
     so to comply would not, singly or in the aggregate, have a Material Adverse
     Effect; all of the Governmental Licenses are valid and in full force and
     effect, except as disclosed in the Offering Circular and except where the
     invalidity of such Governmental Licenses or the failure of such
     Governmental Licenses to be in full force and effect would not have a
     Material Adverse Effect; and none of the Business, Triad, Holdings or any
     of the Designated Subsidiaries has received any notice of proceedings
     relating to the revocation or modification of any such Governmental
     Licenses which, singly or in the aggregate, if the subject of an
     unfavorable decision, ruling or finding, would result in a Material Adverse
     Effect, except as disclosed in the Offering Circular. Each of the Business,
     Triad and Holdings possess such permits, licenses, approvals, consents and
     other authorizations (collectively, "Authorizations") which are necessary
     for Holdings and its subsidiaries to participate, after giving effect to

     Material Adverse Effect; each of the Business, Triad, Holdings and
     Designated Subsidiaries is in compliance with the terms and conditions of
     all such Authorizations, except where the failure so to comply would not,
     singly or in the aggregate, have a Material Adverse Effect; all such
     Authorizations are valid and in full force and effect, except where the
     invalidity of such Authorizations or the failure of such Authorizations to
     be in full force and effect would not have a Material Adverse Effect; and
     none of the Business, Triad, Holdings or any of the Designated Subsidiary
     has received any notice of proceedings relating to the revocation or
     modification of any such Authorizations which, singly or in the aggregate,
     if the subject of an unfavorable decision, ruling or finding, would result
     in a Material Adverse Effect.

     (r) Medicare and Medicaid. To the extent described in the Offering
     Circular and except as otherwise described in the Offering Circular, all
     facilities to be owned, operated or managed as continuing operations by
     Holdings and its subsidiaries after giving effect to the Distribution (the
     "Company Facilities") (i) are, and after the Distribution, will be

     for reimbursement, except, in each case, where the failure to be so
     licensed or certified, to have such contracts, to be in such compliance or
     to have such approvals or qualifications, singly or in the aggregate, would
     not have a Material Adverse Effect. To the knowledge of each of
     Healthtrust, Triad and Holdings, the amounts established as provisions for
     Medicare and Medicaid adjustments and adjustments by any other third party
     payors on the financial statements of Triad are sufficient in all material
     respects to pay any amounts for which Holdings or any of its subsidiaries
     may be liable for such adjustments. Except as described in the Offering
     Circular, none of the Business, Triad, Holdings or any of the Designated


     Subsidiaries has received notice from the regulatory authorities which
     enforce the statutory or regulatory provisions in respect of the Medicare
     or Medicaid programs of any pending or threatened investigations, surveys
     (other than routine surveys) or decertification proceedings, and none of
     Healthtrust, Triad, Holdings or any of their respective subsidiaries has
     any reason to believe that any such investigations, surveys or proceedings
     are pending, threatened or imminent, in each case, which notices or
     threatened investigations, surveys or proceedings singly or in the
     aggregate would have a Material Adverse Effect.

     Subsidiaries under any of the leases or subleases mentioned above, or
     affecting or questioning the rights of any of the Business, Triad, Holdings

     respect of, in the United States or to any United States citizen or
     resident, any security which is or would be integrated with the sale of the
     Securities in a manner that would require the Securities to be registered

     (w) Rule 144A Eligibility. Assuming compliance with the representations in
     Section 3 hereof, the Securities are eligible for resale pursuant to Rule

     (the "Exchange Act"), or quoted in a U.S. automated interdealer quotation
     system.

     (x) No General Solicitation. None of Healthtrust, Triad, Holdings, its

     of the Securities, in any form of general solicitation or general
     advertising within the meaning of Rule 502(c) under the Act.


     (y) No Registration Required. Subject to compliance by the Purchasers with

     become absolute and matured, (iii) Healthtrust, Triad and Holdings, as the
     case may be, able to realize upon its assets and pay its debts and other

     Problem. As a result of such review, except as described in the Offering
     Circular each of Healthtrust, Triad and Holdings has no reason to believe,
     and does not believe, that the Year 2000 Problem will have a Material
     Adverse Effect. The "Year 2000 Problem" as used herein means any
     significant risk that computer hardware or software used in the receipt,
     transmission, processing, manipulation, storage, retrieval, retransmission
     or other utilization of data or in the operation of mechanical or
     electrical systems of any kind will not, in the case of dates or time

     of the Securities) will violate or result in a violation of Section 7 of
     the Exchange Act, or any regulation promulgated thereunder, including,
     without limitation, Regulations T, U and X of the Board of Governors of the
     Federal Reserve System.

     (ii) Healthtrust Assets. (i) The only material assets owned by Columbia/HCA
     are the capital stock of Healthtrust and intercompany notes in an amount
     not to exceed $1,800,000,000 and (ii) other then as described in clause

to resell the Exchange Notes pursuant to Section 4(1) of the Act, all in
accordance with the provisions of the Registration Rights Agreement.

6. The Company covenants and agrees with the several Purchasers that the Company
will pay or cause to be paid the following: (i) the fees, disbursements and
expenses of the Company's counsel and accountants in connection with the issue
of the Securities and all other expenses in connection with the preparation,
printing and filing of the Preliminary Offering Circular and the Final Offering

delivering of copies thereof to the Purchasers and dealers; (ii) the cost of
printing or producing any Agreement among Purchasers, this Agreement, the
Indenture, the Registration Rights Agreement, the Blue Sky survey, closing

(iii) all expenses in connection with the qualification of the Securities for

Sky and legal investment surveys; (iv) any fees charged by securities rating
services for rating the Securities; (v) the cost of preparing the Securities;
(vi) the fees and expenses of the Trustee and any agent of the Trustee and the

the Indenture and the Securities; and (vii) all other costs and expenses
incident to the performance of its obligations hereunder which are not otherwise
specifically provided for in this Section. It is understood, however, that,
except as provided in this Section, and Sections 8 and 11 hereof, the Purchasers
will pay all of their own costs and expenses, including the fees of their
counsel, transfer taxes on resale of any of the Securities by them, and any
advertising expenses connected with any offers they may make.

7. The obligations of the Purchasers hereunder shall be subject, in their
discretion, to the condition that all representations and warranties and other

8. (a) The Company and, upon execution of the Guarantor Assumption Agreement,
each guarantor will indemnify and hold harmless each Purchaser against any
losses, claims, damages or liabilities, joint or several, to which such
Purchaser may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of


a material fact contained in any Preliminary Offering Circular or the Final
Offering Circular, or any amendment or supplement thereto, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
necessary to make the statements therein in light of the circumstances under
which they were made not misleading, and will reimburse each Purchaser for any
legal or other expenses reasonably incurred by such Purchaser in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Offering Circular or the Final Offering
Circular or any such amendment or supplement in reliance upon and in conformity
with written information furnished to the Company by or on behalf of any
Purchaser through Goldman, Sachs & Co. expressly for use therein. It is
understood and agreed that the only written information furnished by any
Purchaser for inclusion in the Preliminary Offering Circular or the Final
Offering Circular consists of the following information in the Offering
Circular: (i) the stabilization legend on page ii, (ii) the second sentence
under the caption "Risk Factors-You May Not Be Able to Sell Your Notes", (iii)
the last paragraph on the front cover and (iv) the sixth, seventh, eighth and
ninth paragraphs under the caption "Underwriting".

(b) Each Purchaser will indemnify and hold harmless the Company against any
losses, claims, damages or liabilities to which the Company may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Offering Circular or the Final Offering Circular, or any amendment
or supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in any Preliminary Offering Circular or the Final Offering
Circular or any such amendment or supplement in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such
Purchaser through Goldman, Sachs & Co. expressly for use therein; and will
reimburse the Company for any legal or other expenses reasonably incurred by the
Company in connection with investigating or defending any such action or claim
as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b)
above of notice of the commencement of any action, such indemnified party shall,
if a claim in respect thereof is to be made against the indemnifying party under
such subsection, notify the indemnifying party in writing of the commencement
thereof; but the omission so to notify the indemnifying party shall not relieve
it from any liability which it may have to any indemnified party otherwise than
under such subsection. In case any such action shall be brought against any
indemnified party and it shall notify the indemnifying party of the commencement
thereof, the indemnifying party shall be entitled to participate therein and, to
the extent that it shall wish, jointly with any other indemnifying party
similarly notified, to assume the defense thereof, with


counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (i)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (ii) does not include a statement as to,
or an admission of, fault, culpability or a failure to act, by or on behalf of
any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to or
insufficient to hold harmless an indemnified party under subsection (a) or (b)
above in respect of any losses, claims, damages or liabilities (or actions in
respect thereof) referred to therein, then each indemnifying party shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (or actions in respect thereof)
in such proportion as is appropriate to reflect the relative benefits received
by the Company on the one hand and the Purchasers on the other from the offering
of the Securities. If, however, the allocation provided by the immediately
preceding sentence is not permitted by applicable law or if the indemnified
party failed to give the notice required under subsection (c) above, then each
indemnifying party shall contribute to such amount paid or payable by such
indemnified party in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company on the one hand and
the Purchasers on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and the Purchasers on the other
shall be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the Purchasers, in each case
as set forth in the Offering Circular. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or the Purchasers
on the other and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The Company
and the Purchasers agree that it would not be just and equitable if contribution
pursuant to this subsection (d) were determined by pro rata allocation (even if
the Purchasers were treated as one entity for such purpose) or by any other
method of allocation which does not take account of the equitable considerations
referred to above in this subsection (d). The amount paid or payable by an
indemnified party as a result of the losses,


claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (d), no Purchaser shall be required to contribute any amount in
excess of the amount by which the total price at which the Securities
underwritten by it and distributed to investors were offered to investors
exceeds the amount of any damages which such Purchaser has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. The Purchasers' obligations in this subsection (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

(e) The obligations of the Company under this Section 8 shall be in addition to
any liability which the Company may otherwise have and shall extend, upon the
same terms and conditions, to each person, if any, who controls any Purchaser
within the meaning of the Act; and the obligations of the Purchasers under this
Section 8 shall be in addition to any liability which the respective Purchasers
may otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company and to each person, if any, who controls the
Company within the meaning of the Act.

9. (a) If any Purchaser shall default in its obligation to purchase the
Securities which it has agreed to purchase hereunder, you may in your discretion
arrange for you or another party or other parties to purchase such Securities on
the terms contained herein. If within twenty-four hours after such default by
any Purchaser you do not arrange for the purchase of such Securities, then the
Company shall be entitled to a further period of twenty-four hours within which
to procure another party or other parties satisfactory to you to purchase such
Securities on such terms. In the event that, within the respective prescribed
periods, you notify the Company that you have so arranged for the purchase of
such Securities, or the Company notifies you that it has so arranged for the
purchase of such Securities, you or the Company shall have the right to postpone
the Time of Delivery for a period of not more than seven days, in order to
effect whatever changes may thereby be made necessary in the Offering Circular,
or in any other documents or arrangements, and the Company agrees to prepare
promptly any amendments to the Offering Circular which in your opinion may
thereby be made necessary. The term "Purchaser" as used in this Agreement shall
include any person substituted under this Section with like effect as if such
person had originally been a party to this Agreement with respect to such
Securities.

(b) If, after giving effect to any arrangements for the purchase of the
Securities of a defaulting Purchaser or Purchasers by you and the Company as
provided in subsection (a) above, the aggregate principal amount of such
Securities which remains unpurchased does not exceed one-eleventh of the
aggregate principal amount of all the Securities, then the Company shall have
the right to require each non-defaulting Purchaser to purchase the principal
amount of Securities which such Purchaser agreed to purchase hereunder


and, in addition, to require each non-defaulting Purchaser to purchase its pro
rata share (based on the principal amount of Securities which such Purchaser
agreed to purchase hereunder) of the Securities of such defaulting Purchaser or
Purchasers for which such arrangements have not been made; but nothing herein
shall relieve a defaulting Purchaser from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the
Securities of a defaulting Purchaser or Purchasers by you and the Company as
provided in subsection (a) above, the aggregate principal amount of Securities
which remains unpurchased exceeds one-eleventh of the aggregate principal amount
of all the Securities, or if the Company shall not exercise the right described
in subsection (b) above to require non-defaulting Purchasers to purchase
Securities of a defaulting Purchaser or Purchasers, then this Agreement shall
thereupon terminate, without liability on the part of any non-defaulting
Purchaser or the Company, except for the expenses to be borne by the Company and
the Purchasers as provided in Section 6 hereof and the indemnity and
contribution agreements in Section 8 hereof; but nothing herein shall relieve a
defaulting Purchaser from liability for its default.

10. The respective indemnities, agreements, representations, warranties and
other statements of the Company and the several Purchasers, as set forth in this
Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Purchaser or any controlling person of any Purchaser, or the Company, or
any officer or director or controlling person of the Company, and shall survive
delivery of and payment for the Securities. Notwithstanding the foregoing, the
parties hereto acknowledge and agree that the representations and warranties
relating to Healthtrust or Columbia/HCA and their respective subsidiaries (other
than the Business, Triad, Holdings and the Designated Subsidiaries) shall
survive only until the assumption of the indebtedness evidenced by the
Securities by Holdings has occurred and the Distribution has been consummated.

11. If this Agreement shall be terminated pursuant to Section 9 hereof, the
Company shall not then be under any liability to any Purchaser except as
provided in Sections 6 and 8 hereof; but, if for any other reason, the
Securities are not delivered by or on behalf of the Company as provided herein,
the Company will reimburse the Purchasers through you for all out-of-pocket
expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Purchasers in making preparations for the
purchase, sale and delivery of the Securities, but the Company shall then be
under no further liability to any Purchaser except as provided in Sections 6 and
8 hereof.

12. In all dealings hereunder, you shall act on behalf of each of the
Purchasers, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Purchaser made or given
by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives.



All statements, requests, notices and agreements hereunder shall be in writing,
and if to the Purchasers shall be delivered or sent by mail, telex or facsimile
transmission to you as the representatives in care of Goldman, Sachs & Co., 32
Old Slip, 9th Floor, New York, New York 10005, Attention: Registration
Department; and if to the Company shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Company set forth in the Offering
Circular, Attention: Secretary; provided, however, that any notice to a
Purchaser pursuant to Section 8(c) hereof shall be delivered or sent by mail,
telex or facsimile transmission to such Purchaser at its address set forth in
its Purchasers' Questionnaire, or telex constituting such Questionnaire, which
address will be supplied to the Company by you upon request. Any such
statements, requests, notices or agreements shall take effect upon receipt
thereof.

13. This Agreement shall be binding upon, and inure solely to the benefit of,
the Purchasers, the Company and, to the extent provided in Sections 8 and 10
hereof, the officers and directors of the Company and each person who controls
the Company or any Purchaser, and their respective heirs, executors,
administrators, successors and assigns, and no other person shall acquire or
have any right under or by virtue of this Agreement. No purchaser of any of the
Securities from any Purchaser shall be deemed a successor or assign by reason
merely of such purchase.

14. This Agreement shall be governed by and construed in accordance with the
laws of the State of New York.

15. This Agreement may be executed by any one or more of the parties hereto in
any number of counterparts, each of which shall be deemed to be an original, but
all such respective counterparts shall together constitute one and the same
instrument.



     If the foregoing is in accordance with your understanding, please sign and
return to us one for the Company and each of the Representatives plus one for
each counsel counterparts hereof, and upon the acceptance hereof by you, on
behalf of each of the Purchasers, this letter and such acceptance hereof shall
constitute a binding agreement between each of the Purchasers and the Company.
It is understood that your acceptance of this letter on behalf of each of the
Purchasers is pursuant to the authority set forth in a form of Agreement among
Purchasers, the form of which shall be submitted to the Company for examination
upon request, but without warranty on your part as to the authority of the
signers thereof.


                                          Very truly yours,
