The Selling Shareholders understand that the Underwriter proposes to make a public offering of the Securities as soon as the Underwriter deems advisable after this Agreement has been executed and delivered.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-175791), as amended by post-effective amendments Nos. 1, 2 and 3 thereto, which registration statement contains a base prospectus relating to securities, including the Common Stock, to be issued from time to time by the Company (the “Base Prospectus”). The Company has also filed or proposes to file, with the Commission pursuant to Rule 424 under the Securities Act of 1933, as amended (the “1933 Act”), a prospectus supplement specifically relating to the Securities (the “Prospectus Supplement”).

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 1933 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 “1934 Act”), and incorporated by reference in such Registration Statement, any Preliminary Prospectus or Prospectus, as the case may be.

(i) Issuer Free Writing Prospectuses. The Company agrees that, unless it obtains the prior written consent of the Underwriter, it will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus,” or a portion thereof, required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the Underwriter will be deemed to have consented to the Issuer Free Writing Prospectuses listed on Schedule B-2 hereto and any “road show that is a written communication”

within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and who, at the date of this Agreement, is a director or officer of the Company or controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, the Company has been advised that in the opinion of the Commission such provisions may contravene Federal public policy as expressed in the 1933 Act and may therefore be unenforceable. In the event that a claim for indemnification under such agreement for any such liabilities (except insofar as such agreement provides for the payment by the Company of expenses incurred or paid by a director, officer or controlling person in the successful defense of any action, suit or proceeding) is asserted by such a person, the Company will submit to a court of appropriate jurisdiction (unless in the opinion of counsel for the Company the matter has already been settled by controlling precedent) the question of whether or not indemnification by it for such liabilities is against public policy as expressed in the 1933 Act and therefore unenforceable, and the Company will be governed by the final adjudication of such issue.

(b) Indemnification by Selling Shareholders.

(i) Each Selling Shareholder, severally and not jointly, agrees to indemnify and hold harmless the Underwriter, its Affiliates and selling agents and each person, if any, who controls the Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act to the extent and in the manner set forth in clauses (a)(i), (ii) and (iii) above and in Section 6(e) and Section 6(f); provided that each Selling Shareholder shall be liable only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any preliminary prospectus, the Prospectus (or any amendment or supplement thereto) or any Issuer Free Writing Prospectus in reliance upon and in conformity with the Selling Shareholder Information; provided, further, that the liability under this subsection of each Selling Shareholder shall be limited to an amount equal to the aggregate gross proceeds after underwriting commissions and discounts, but before expenses, to such Selling Shareholder from the sale of Securities sold by such Selling Shareholder hereunder.

(ii) Each Selling Shareholder, severally and not jointly, agrees to indemnify and hold harmless the Company, its Affiliates and selling agents and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the foregoing indemnity from the Company to each Underwriter; provided that each Selling Shareholder shall be liable only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any preliminary prospectus, the Prospectus (or any amendment or supplement thereto) or any Issuer Free Writing Prospectus in reliance upon and in conformity with the Selling Shareholder Information; provided, further, that the liability under this subsection of each Selling Shareholder shall be limited to an amount equal to the aggregate gross proceeds after underwriting commissions and discounts, but before expenses, to such Selling Shareholder from the sale of Securities sold by such Selling Shareholder hereunder

(c) Indemnification of Company, Directors and Officers and Selling Shareholders. The Underwriter agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and each Selling Shareholder and each person, if any, who controls a Selling Shareholder within

-23-

the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(d) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) and 6(b) above, counsel to the indemnified parties shall be selected by the Underwriter, and, in the case of parties indemnified pursuant to Section 6(c) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.

(e) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into, (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement and (iv) the indemnified party and the indemnifying party have not otherwise reached an agreement regarding reimbursement of the indemnified party.

(f) Other Agreements with Respect to Indemnification. The provisions of this Section shall not affect any agreement among the Company and the Selling Shareholders with respect to indemnification.

SECTION 7. Contribution.

If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits

-24-

received by the Company, the Selling Shareholders and the Underwriter, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, the Selling Shareholders and of the Underwriter in connection with the statements or omissions, or in connection with any violation of the nature referred to in Section 6(g) hereof, which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, the Selling Shareholders and the Underwriter, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, the Selling Shareholders and the total underwriting discount received by the Underwriter, in each case, as set forth on the cover of the Prospectus, bear to the aggregate public offering price of the Securities as set forth on the cover of the Prospectus.

The relative fault of the Company the Selling Shareholders and the Underwriter shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, the Selling Shareholders or by the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or any violation of the nature referred to in Section 6(g) hereof.

The Company, the Selling Shareholders and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriter 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 Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, the Underwriter shall not be required to contribute any amount in excess of the underwriting discount or commission applicable to the Securities purchased by the Underwriter hereunder.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 0000 Xxx) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls the Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and the Underwriter’s Affiliates, its selling agents and its and their respective officers, directors and employees shall have the same rights to contribution as the Underwriter, and each director of the Company,

-25-

each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company or any Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company or such Selling Shareholder, as the case may be.

The provisions of this Section shall not affect any agreement among the Company and the Selling Shareholders with respect to contribution.

SECTION 8. Representations, Warranties and Agreements to Survive.

All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries or the Selling Shareholders submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Underwriter or its Affiliates or selling agents, any person controlling the Underwriter, its officers or directors, any person controlling the Company or any person controlling any Selling Shareholder and (ii) delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination. The Underwriter, in its absolute discretion, may terminate this Agreement without liability to the Company, by notice to the Company and the Selling Shareholders, at any time at or prior to the Closing Time (i) there shall have occurred any outbreak of hostilities or escalation thereof or other calamity or crisis in each case the effect of which on financial markets is such as to make it, in the judgment of the Underwriter, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Securities, or (ii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or (iii) if trading generally on the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or (v) if a banking moratorium has been declared by either Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, 15 and 16 shall survive such termination and remain in full force and effect.

SECTION 10. Reserved.

SECTION 11. Default by the Company.

If the Company shall fail at the Closing Time to sell the number of Securities that it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any nondefaulting party; provided, however, that the provisions of Sections 1, 4, 6, 7, 8, 15 and 16 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default.

Re: HCA Holdings, Inc. – Public Offering

Dear Sirs:

The undersigned, a stockholder [and an officer and/or director] of HCA Holdings, Inc., a Delaware corporation (the “Company”), understands that Xxxxxx Xxxxxxx & Co. LLC proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company and the Selling Shareholders providing for a public offering of shares (the “Securities”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”). In recognition of the benefit that such an offering will confer upon the undersigned as a stockholder [and an officer and/or director] of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Underwriting Agreement that, during a period of 45 days from the date of the Underwriting Agreement, the undersigned will not, without the prior written consent of Xxxxxx Xxxxxxx & Co. LLC, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of the Company’s Common Stock or any securities convertible into or exchangeable or exercisable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition (collectively, the “Lock-Up Securities”), or exercise any right with respect to the registration of any of the Lock-up Securities, or file or cause to be filed any registration statement in connection therewith, under the Securities Act of 1933, as amended, or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise.

Notwithstanding the foregoing, and subject to the conditions below, the undersigned may transfer the Lock-Up Securities without the prior written consent of Xxxxxx Xxxxxxx & Co. LLC; provided that (1) Xxxxxx Xxxxxxx & Co. LLC receive a signed lock-up agreement for the balance of the lockup period from each donee, trustee, distributee, or transferee, as the case may be, (2) any such transfer shall not involve a disposition for value, (3) such transfers are not required to be reported in any public report or filing with the Securities and Exchange Commission, and (4) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers:

(i) as a bona fide gift or gifts; or

Exhibit B-1

(ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this lock-up agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin); or

(iii) as a distribution to limited partners, members or stockholders of the undersigned; or

(iv) to the undersigned’s affiliates or to any investment fund or other entity controlled by the undersigned.

Furthermore, the undersigned may (1) sell shares of Common Stock of the Company purchased by the undersigned on the open market following the public offering if and only if (i) such sales are not required to be reported in any public report or filing with the Securities Exchange Commission, or otherwise and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding such sales or (2) exercise options to purchase shares of Common Stock or receive shares of Common Stock upon the vesting of restricted stock awards in each case pursuant to employee benefit plans disclosed in the Prospectus and effect the related transfer of shares of Common Stock to the Company (i) deemed to occur upon the cashless exercise of such options or (ii) for the primary purpose of paying the exercise price of such options or for paying taxes (including estimated taxes) due as a result of the exercise of such options or as a result of the vesting of such shares of Common Stock under such restricted stock awards.

[Notwithstanding anything contained herein to the contrary, the undersigned may transfer the Lock-Up Securities without the prior written consent of Xxxxxx Xxxxxxx & Co. LLC to any of its members that will not participate in the public offering of the Securities pursuant to the terms and subject to the conditions of the Underwriting Agreement up to a pro rata percentage of shares of Common Stock that could have been sold in the public offering by such member’s Investor Group (as defined in the Limited Liability Company Agreement of Hercules Holdings II, LLC.]¹
