(e) If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which, in the opinion of counsel for the Underwriters or the Company, the Disclosure Package as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances, not misleading or (ii) it is necessary to amend or supplement the Disclosure Package to comply with law, the Company will promptly notify CGMI on behalf of the Representatives thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Disclosure Package as may be necessary so that the statements in the Disclosure Package as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Disclosure Package will comply with law.

(g) The Company will use reasonable best efforts to assist the Underwriters in arranging, if necessary, for the qualification of the Securities for sale by the Underwriters under the applicable securities laws of such jurisdictions in the United States as the Representatives may designate and will maintain such qualifications in effect so long as required for the sale of the Securities; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would reasonably be expected to subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject or to subject themselves to taxation in excess of a nominal amount in respect of doing business in any jurisdiction. The Company will promptly advise CGMI, on behalf of the Representatives, of the receipt by it of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(h) The Company will cooperate with the Representatives and use its commercially reasonable efforts to permit the Securities to be eligible for clearance and settlement through DTC.

(i) The Company will not, for a period of 30 days following the date of the Prospectus, without the prior written consent of CGMI, offer, sell or contract to sell, pledge or otherwise dispose of (or enter into any transaction that is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any of its Affiliates or any person in privity with the Company or any of its Affiliates), directly or indirectly, or announce the offering of, any capital markets debt securities issued or guaranteed by the Company (other than the Securities) or HCA Inc.

15

amendments or supplements to either of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (iv) the printing (or reproduction) and delivery of any blue sky memorandum to investors in connection with the offering of the Securities; (v) any registration or qualification of the Securities for offer and sale under the securities or blue sky laws of the several states and any other jurisdictions specified pursuant to Section 5(g) (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such registration and qualification); (vi) the approval of the Securities for book-entry transfer by DTC; (vii) the transportation and other expenses incurred by or on behalf of representatives of the Company in connection with presentations to prospective purchasers of the Securities; (viii) the fees and expenses of the Company’s accountants and the fees and expenses of counsel (including local and special counsel) to the Company; (ix) the rating of the Securities by rating agencies; and (x) all other costs and expenses incident to the performance by the Company of its obligations hereunder; provided , however , that except as specifically provided in this paragraph (j), in Section 7 and in Section 8, the Underwriters shall pay their own costs and expenses in connection with presentations for prospective purchasers of the Securities.

(k) The Company will use the proceeds from the sale of the Securities in the manner described in each of the Registration Statement, the Disclosure Package and the Prospectus under the caption “Use of Proceeds.”

(l) The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, no Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

(m) The Company will, pursuant to reasonable procedures developed in good faith, retain copies of each Issuer Free Writing Prospectus that is not filed with the Commission in accordance with Rule 433 under the Act.

6. Conditions to the Obligations of the Underwriters . The obligations of the Underwriters to purchase the Securities shall be subject to the accuracy in all material respects (except to the extent already qualified by materiality, in which case such obligations shall be subject to the accuracy in all respects) of the representations and warranties of the Company contained herein at the Applicable Time, to the accuracy in all material respects (except to the extent

16

already qualified by materiality, in which case such obligations shall be subject to the accuracy in all respects) of the representations and warranties of the Company contained herein at the Closing Date, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:

(a) No order suspending the effectiveness of the Registration Statement shall be in effect, and no proceeding for such purpose, pursuant to Rule 401(g)(2) or pursuant to Section 8A under the Act shall be pending before or threatened by the Commission; the Prospectus and each Issuer Free Writing Prospectus shall have been timely filed with the Commission under the Act (in the case of an Issuer Free Writing Prospectus, to the extent required by Rule 433 under the Act) and in accordance with Section 5(a) hereof; and all requests by the Commission for additional information shall have been complied with to the reasonable satisfaction of the Representatives.

(b) The Company shall have requested and caused Simpson Thacher & Bartlett LLP, counsel for the Company, to furnish to the Underwriters an opinion letter and an advice letter, each dated the Closing Date and substantially in the forms of Exhibit A and Exhibit B , respectively, hereto and an opinion of Bass, Berry & Sims PLC, special regulatory counsel for the Company, dated the Closing Date and substantially in the form of Exhibit C hereto. The Company shall have requested and caused the general counsel of the Company to furnish to the Underwriters an opinion letter with regards to such matters as the Representatives shall reasonably require.

(c) The Underwriters shall have received from Cahill Gordon & Reindel LLP , counsel for the Underwriters, such opinion letter and advice letter, each dated the Closing Date and addressed to the Underwriters, with respect to the issuance and sale of the Securities, the Indentures, the Disclosure Package and the Prospectus (as amended or supplemented at the Closing Date) and other related matters as the Underwriters may reasonably require; and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters.

(d) The Company shall have furnished to the Underwriters a certificate of the Company, signed by (x) the chairman, chief executive officer, president or vice president and (y) the chief financial officer, treasurer or principal financial or accounting officer of the Company, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Disclosure Package and the Prospectus, any amendment or supplement to the Disclosure Package or the Prospectus and this Agreement and that:

(i) the representations and warranties of the Company in this Agreement are true and correct in all material respects (except to the extent already qualified by materiality, in which case such representations and warranties are true and correct in all respects) at the Applicable Time and on the Closing Date, and the Company has complied in all material respects with all the agreements and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; and

(ii) since the date of the most recent financial statements included or incorporated by reference in each of the Disclosure Package and the Prospectus (exclusive of any amendment or supplement thereto), there has been no material adverse change in the condition (financial or otherwise), business or results of operations of the Company and its subsidiaries, taken as a whole, except as set forth in or contemplated in the Disclosure Package and the Prospectus (exclusive of any amendment or supplement thereto).

17

(e) At the Applicable Time and at the Closing Date, the Company shall have requested and caused Ernst & Young LLP to furnish to the Underwriters a “comfort” letter, dated as of the Applicable Time, and a bring-down “comfort letter,” dated as of the Closing Date, respectively, in form and substance reasonably satisfactory to the Representatives, confirming that they are independent registered public accountants within the meaning of the Exchange Act and within the meaning of the rules of the Public Company Accounting Oversight Board and confirming certain matters with respect to the audited and unaudited financial statements and other financial and accounting information contained in the Registration Statement, the Disclosure Package and the Prospectus, including any amendment or supplement thereto at the date of the applicable letter.

(f) Subsequent to the Applicable Time or, if earlier, the dates as of which information is given in the Disclosure Package and the Prospectus (exclusive of any amendment or supplement thereto), there shall not have been any change or development in the condition (financial or otherwise), business or results of operations of the Company and its subsidiaries, taken as a whole, and after giving effect to the Transaction, except as set forth in or contemplated in the Disclosure Package and the Prospectus (exclusive of any amendment or supplement thereto), the effect of which is, or would reasonably be expected to become, in the judgment of CGMI, so material and adverse as to make it impractical or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated in the Registration Statement, the Disclosure Package and the Prospectus (exclusive of any amendment or supplement thereto).

(g) At the Closing Date, the Company and the Trustee shall have entered into the Indenture, and the Representatives shall have received counterparts, conformed as executed, thereof.

(i) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request, as set forth in the closing memorandum relating to the offering of the Securities.

(j) Prior to the Closing Date, the Company shall have taken all action reasonably required to be taken by it to have the Securities declared eligible for clearance and settlement through DTC.

The documents required to be delivered by this Section 6 will be available for inspection at the office of Simpson Thacher & Bartlett LLP, at 425 Lexington Avenue, New York, New York 10017, on the Business Day prior to the Closing Date.

7. Reimbursement of Expenses . If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or to comply with any provision hereof other than by reason of a default by any of the Underwriters, including as described in Section 9 hereof, the Company will reimburse the Underwriters through the Representatives on behalf of the Underwriters on demand for all reasonable expenses (including reasonable fees and disbursements of Cahill Gordon & Reindel LLP ) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

8. Indemnification and Contribution .

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers and Affiliates of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, (ii) or any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), the Disclosure Package, any Issuer Free Writing Prospectus or any written communication that constitutes an offer to sell or a solicitation of any offer to buy the Securities used by the Company in violation of the provisions of this Agreement, 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 the light of the circumstances under which they were made, not misleading, and agree (subject to the limitations set forth in the provisos to this sentence) to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided , however , that the Company will not be liable in any such case to the extent that any such loss, claim, damage

19

or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Prospectus (or any amendment or supplement thereto), the Disclosure Package or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Company may otherwise have. The Company shall not be liable under this Section 8 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent is consented to by the Company which consent shall not be unreasonably withheld.

(b) Each Underwriter severally, and not jointly, agrees to indemnify and hold harmless (i) the Company, (ii) each person, if any, who controls (within the meaning of either the Act or the Exchange Act) the Company, and (iii) the directors and officers of the Company, to the same extent as the foregoing indemnity from the Company, to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the Registration Statement, the Prospectus (or any amendment or supplement thereto), the Disclosure Package or any Issuer Free Writing Prospectus. This indemnity agreement will be in addition to any liability that any Underwriter may otherwise have. The Company acknowledges that the fifth, tenth, fifteenth, sixteenth and seventeenth paragraphs and the second sentence of the seventh paragraph under the heading “Underwriting” in the Disclosure Package and the Prospectus constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in the Registration Statement, the Prospectus (or any amendment or supplement thereto), the Disclosure Package or any Issuer Free Writing Prospectus.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights or defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above, except as provided in paragraph (d) below. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided , however , that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear

20

the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest (based on the advice of counsel to the indemnified person); (ii) such action includes both the indemnified party and the indemnifying party, and the indemnified party shall have reasonably concluded (based on the advice of counsel to the indemnified person) that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. It is understood and agreed that the indemnifying person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all indemnified persons. Any such separate firm for any Underwriter, its Affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by CGMI, and any such separate firm for the Company and any control persons, officers or directors of the Company shall be designated in writing by the Company. In the event that any Underwriter, its Affiliates, directors and officers or any control persons of such Underwriter are Indemnified Persons collectively entitled, in connection with a proceeding in a single jurisdiction, to the payment of fees and expenses of a single separate firm under this Section 8(c), and any such Underwriter, its Affiliates, directors and officers or any control persons of such Underwriter cannot agree to a mutually acceptable separate firm to act as counsel thereto, then such separate firm for all such Indemnified Persons shall be designated in writing by CGMI. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any statement as to, or any admission of, fault, culpability or failure to act by or on behalf of any indemnified party.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason (other than by virtue of the failure of an indemnified party to notify the indemnifying party of its right to indemnification pursuant to subsection (a) or (b) above, where such failure materially prejudices the indemnifying party (through the forfeiture of substantial rights or defenses)), the Company, on the one hand, and the Underwriters, on the other hand, severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively “ Losses ”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and by the Underwriters, on the other hand, from the offering of the Securities. If the allocation provided by the immediately preceding sentence is unavailable for any reason or not permitted by applicable law, the Company, on the one hand, and the Underwriters, on the other hand, severally shall contribute in such proportion as is appropriate to

21

reflect not only such relative benefits but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by its, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions received by them. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company, on the one hand, or the Underwriters, on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission and any other equitable considerations appropriate in the circumstances. The Company and the Underwriters agree that it would not be just and equitable if the amount of such contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Notwithstanding the provisions of this Section 8, in no event under this Section 8(d) shall any Underwriter be responsible for any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact. The Underwriters’ obligations to contribute pursuant to this Section 8 are several in proportion to their respective purchase obligations hereunder and not joint. For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act and the officers and directors of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Underwriter . If any one or more Underwriters shall fail to purchase and pay for the Securities agreed to be purchased by such Underwriter hereunder, and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions that the principal amount of the Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of the Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided , however , that in the event that the aggregate principal amount of the Securities that the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the Company shall be entitled to a period of 36 hours within which to procure another party or parties reasonably satisfactory to the non-defaulting Underwriters, as the case may be, to purchase no less than the amount of such unpurchased Securities that exceeds 10% of the principal amount thereof upon such terms herein set forth. If, however, the Company shall not have completed such arrangements within 72 hours after such default and

22

the principal amount of unpurchased Securities exceeds 10% of the principal amount of such Securities to be purchased on such date, then this Agreement will terminate without liability to any non-defaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, to effect any changes that in the opinion of counsel for the Company or counsel for the Representatives are necessary in the Registration Statement and the Prospectus or in any other documents or arrangements.
