          HCA Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several parties named in Schedule I hereto (each an “Underwriter” and together, the “Underwriters”), for whom you (the “Representatives”) are acting as representatives of, the respective amounts set forth in such Schedule I of $500,000,000 aggregate principal amount of its 8% Senior Notes due 2018 (the “Securities”).

          The Securities will be unconditionally guaranteed on a senior unsecured basis (the “Guarantee”) by HCA Holdings, Inc., a Delaware corporation and the Company’s parent (the “Parent Guarantor”).

          In connection with the offer and sale of the Securities, the Company and the Parent Guarantor have prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-175791), which contains a

base prospectus relating to the debt securities to be issued from time to time by the Company (the “Base Prospectus”). The Company has also filed or proposed to file, with the Commission pursuant to Rule 424 under the Act a prospectus supplement specifically relating to the Securities (the “Prospectus Supplement”). Such registration statement, as amended at the time it became effective under the Act, including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430A, 430B or 430C under the Act (the “Rule 430 Information”), is called the “Registration Statement.” The term “Prospectus” shall mean the Base Prospectus as supplemented by the Prospectus Supplement specifically relating to the Securities in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Act) in connection with the confirmation and sales of the Securities, and the term “Preliminary Prospectus” means the preliminary prospectus supplement specifically relating to the Securities together with the Base Prospectus. Any reference herein to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Act as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or Prospectus as the case may be; any reference to any amendment or supplement to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after the date of such Registration Statement, any Preliminary Prospectus or Prospectus, as the case may be, under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), and incorporated by reference in such Registration Statement, any Preliminary Prospectus or Prospectus, as the case may be. The term “Disclosure Package” shall mean (i) a Preliminary Prospectus dated September 27, 2011 and (ii) any “free writing prospectus” as defined in Rule 405 of the Act identified in Annex A hereto, which shall include the term sheet prepared pursuant to Section 5 hereto (the “Pricing Term Sheet”), which were available to purchasers of the Securities at or prior to the time when sales of the Securities were first made (the “Applicable Time”).

Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to issue and sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company, at a purchase price of 98.875% of the gross proceeds to the Company (i.e. less a discount of $5,625,000), plus accrued interest, if any, from October 3, 2011 to the Closing Date, the principal amount of the Securities set forth opposite such Underwriter’s name in Schedule I hereto.

          3. Delivery and Payment. Delivery of and payment for the Securities shall be made at the offices of Simpson Thacher & Bartlett LLP, 425 Lexington Avenue, New York, New York 10017, New York City time on October 3, 2011 or at such time on such later date not more than three Business Days after the foregoing date as the Representatives shall designate, which date and time may be postponed by agreement between the Representatives and the Company or as provided in Section 9 hereof (such date and time of delivery and payment for the Securities being herein called the “Closing Date”). Delivery of the Securities shall be made to the Representatives for the respective accounts of the several Underwriters against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the order of the Company by wire transfer payable in same-day funds to the account specified by the Company in writing to the Representatives. Delivery of the Securities shall be made through the facilities of The Depository Trust Company (“DTC”) unless the Representatives shall otherwise instruct.

          4. Offering by Underwriters. Each Underwriter acknowledges that:

     (a) it has not used and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus” as defined under Rule 405 of the Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company), other than (i) a free writing prospectus that, solely

as a result of use by such Underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433 under the Act, (ii) any Issuer Free Writing Prospectus listed in Annex B or prepared pursuant to Section 1(c) above or Section 5(d) below (including any electronic road show), or (iii) any free writing prospectus prepared by such Underwriter and approved by the Company in advance in writing (each such free writing prospectus referred to in clauses (i) or (iii), an “Underwriter Free Writing Prospectus”). Notwithstanding the foregoing, the Underwriters may use a Pricing Term Sheet substantially in the form of Annex A hereto; and

     (b) it is not subject to any proceeding under Section 8A of the Act with respect to the offering (and will promptly notify the Company if any such proceeding against it is initiated during the Prospectus Delivery Period (as defined below)).

          5. Agreements. The Company and the Parent Guarantor jointly and severally agree, in each case with each Underwriter as follows:

     (a) The Company will file the final Prospectus with the Commission within the time periods specified by Rule 424(b) and Rule 430A, 430B or 430C under the Act, will file any Issuer Free Writing Prospectus (including the Pricing Term Sheet in the form of Annex A hereto) to the extent required by Rule 433 under the Act; and will file all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and for so long as the delivery of a prospectus is required in connection with the offering or sale of the Securities; and the Company will furnish copies of the Prospectus and each Issuer Free Writing Prospectus (to the extent not previously delivered, electronically or otherwise) to the Underwriters in New York City on the second business day succeeding the date of this Agreement in such quantities as the Representatives may reasonably request. The Company will pay the registration fees for this offering within the time period required by Rule 456(b)(1)(i) under the Act (without giving effect to the proviso therein) and in any event prior to the Closing Date.

     (b) The Company has (i) furnished or will deliver to the Representatives and counsel for the Underwriters, without charge, signed copies of the Registration Statement as originally filed and each amendment thereto (including exhibits filed therewith) and signed copies of all consents and certificates of experts, and will also deliver to the Representatives, without charge, a conformed copy of the Registration Statement as originally filed and each amendment thereto (without exhibits) for each of the Underwriters. The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. The Company has delivered to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the Act and (ii) Company will furnish to each Underwriter, without charge, during the period when a prospectus relating to the Securities is (or, but for the exception afforded by Rule 172, would be)

required to be delivered under the Act (such period, the “Prospectus Delivery Period”), such number of copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

     (c) Before making, preparing, using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus, and before filing any amendment or supplement to the Registration Statement or the Prospectus, the Company will furnish to Barclays Capital Inc. (“Barclays”) and counsel for the Underwriters a copy of the proposed Issuer Free Writing Prospectus, amendment or supplement for review and will not make, prepare, use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus required to be filed or file any such proposed amendment or supplement to which Barclays reasonably objects.

     (d) The Company will advise the Representatives promptly, and confirm such advice in writing, (i) when any amendment to the Registration Statement has been filed; (ii) when any supplement to the Prospectus or any amendment to the Prospectus or any Issuer Free Writing Prospectus has been filed; (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (iv) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Act; (v) of the occurrence of any event within the Prospectus Delivery Period as a result of which the Prospectus, the Disclosure Package or any Issuer Free Writing Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus, the Disclosure Package or any such Issuer Free Writing Prospectus is delivered to a purchaser, not misleading; (vi) of the receipt by the Company of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Act; and (vii) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Securities for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use every reasonable effort to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus or the Prospectus or suspending any such qualification of the Securities and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

     (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 Barclays 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.

     (f) If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Company will promptly notify Barclays on behalf of the Representatives thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus 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 or the Parent Guarantor 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 Barclays, on behalf of the Representatives, of the receipt by it of any notification with respect to the suspension of the qualification of the Securities or the Guarantee 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 Barclays, 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, the Parent Guarantor or any of their respective Affiliates or any person in privity with the Company, the Parent Guarantor or any of their respective Affiliates), directly or indirectly, or announce the offering of, any capital markets debt securities issued or guaranteed by the Company or the Parent Guarantor (other than the Securities and the Guarantee).

     (j) The Company and the Parent Guarantor jointly and severally agree to pay the costs and expenses incident to the following matters: (i) the fees of the Trustee (and its counsel); (ii) the preparation, printing (or reproduction), delivery (including postage, air freight charges and charges for counting and packaging) and filing under the Act, of such copies of the Registration Statement, the Disclosure Package, and Issuer Free Writing Prospectus and the Prospectus, and all 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 and the Parent Guarantor’s accountants and the fees and expenses of counsel (including local and special counsel) to the Company; and (ix) all other costs and expenses incident to the performance by the Company of their 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 and the Parent Guarantor jointly and severally acknowledge and agree that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company and the Parent Guarantor 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, the Parent Guarantor or any other person. Additionally, no Underwriter is advising the Company, the Parent Guarantor or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company and the Parent Guarantor shall consult with their 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 or the Parent Guarantor with respect thereto. Any review by the Underwriters of the Company and the Parent Guarantor, 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 or the Parent Guarantor.

     (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 and the Parent Guarantor contained herein at the Applicable Time, 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 and the Parent Guarantor contained herein at the Closing Date, to the accuracy of the statements of the Company or the Parent Guarantor 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 a 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 Senior Indenture, 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 and the Parent Guarantor 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 and the Parent Guarantor have 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).

     (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 Parent Guarantor 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 Barclays, 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, the Parent Guarantor and the Trustee shall have entered into the Senior Indenture, and the Representatives shall have received counterparts, conformed as executed, thereof.

     (h) Subsequent to the Applicable Time, there shall not have been any decrease in the rating of the Securities by any “nationally recognized statistical rating organization” (as defined for purposes of the Exchange Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

     (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.

          All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to the Representatives and counsel for the Underwriters.

          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 or the Parent Guarantor 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 and the Parent Guarantor, jointly and severally, 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 and the Parent Guarantor jointly and severally agree 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 or the Parent Guarantor 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 and the Parent Guarantor will 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 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 and the Parent Guarantor may otherwise have. The Company and the Parent Guarantor 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 or the Parent Guarantor, as applicable, which consent shall not be unreasonably withheld.

          (b) Each Underwriter severally, and not jointly, agrees to indemnify and hold harmless (i) the Company and the Parent Guarantor, (ii) each person, if any, who controls (within the meaning of either the Act or the Exchange Act) the Company or the Parent Guarantor, and (iii) the directors and officers of the Company and the Parent Guarantor, to the same extent as the foregoing indemnity from the Company and the Parent Guarantor, 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 and the Parent Guarantor acknowledge that the third, sixth, eighth, ninth, tenth and eleventh paragraphs and the third 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 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 Barclays, and any such separate firm for the Company or the Parent Guarantor and any control persons, officers or directors of the Company or the Parent Guarantor shall be designated in writing by the Company or the Parent Guarantor, as the case may be. 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 Barclays. 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 and the Parent Guarantor, 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 or the Parent Guarantor 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 and the Parent Guarantor, 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 and the Parent Guarantor, on the one hand, and the Underwriters, on the other hand, severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Parent Guarantor, 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 and the Parent Guarantor shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by them, 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 or the Parent Guarantor, 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 Parent Guarantor 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 or the Parent Guarantor within the meaning of either the Act or the Exchange Act and the respective officers and directors of the Company and the Parent Guarantor shall have the same rights to contribution as the Company and the Parent Guarantor, 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 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. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company or any nondefaulting Underwriter for damages occasioned by its default hereunder.

          10. Termination. This Agreement shall be subject to termination in the absolute discretion of a majority of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in any securities generally or trading of any securities issued or guaranteed by the Company or the Parent Guarantor on the New York Stock Exchange or the NASDAQ Global Market shall have been suspended or materially limited or minimum prices shall have been established on such exchange or the NASDAQ Global Market; (ii) a banking moratorium shall have been declared either by U.S. federal or New York state authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the judgment of Barclays, impractical or inadvisable to proceed with the offering, sale or delivery of the Securities

as contemplated in the Disclosure Package and the Prospectus (exclusive of any amendment or supplement thereto).

          11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company and the Parent Guarantor or their respective officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters or the Company and the Parent Guarantor, or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 5(j), 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

          12. Notices. All communications hereunder will be in writing and effective only on receipt and, if sent to the Representatives, will be mailed, delivered or faxed to Barclays Capital Inc., 745 Seventh Avenue, New York, New York 10019, (fax: (636)  ###-###-####); Attention: Syndicate Registration or, if sent to the Company or the Parent Guarantor, will be mailed, delivered or faxed c/o HCA Inc.

The Company shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Underwriters by Barclays.

          13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and at and after the Closing Date, the Company and the Parent Guarantor and their respective successors and the indemnified persons referred to in Section 8 hereof and their respective successors and no other person will have any right or obligation hereunder. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

          14. Applicable Law. THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED WITHIN THE STATE OF NEW YORK. THE PARTIES HERETO EACH HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT.
