(b) The Company will indemnify and hold harmless each Selling Stockholder, its affiliates, directors, officers and employees, and each person, if any, who controls any Selling Stockholder within the meaning of the Act and the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such Selling Stockholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Selling Stockholder for any legal or other expenses reasonably incurred by such Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by any Selling Stockholder expressly for use therein that constitutes the Selling Stockholder Information;

(c) Each of the Selling Stockholders, severally and not jointly, will indemnify and hold harmless each Underwriter, its affiliates, directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Act and the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such Underwriter, its affiliates, directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Act and the Exchange Act may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto, or the omission or alleged omission therefrom to state a material fact required to be stated therein or necessary to make the statement therein not misleading, or (ii) an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, or the omission or alleged omission therefrom to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, in reliance upon and in conformity with the Selling Stockholder Information; and will reimburse each Underwriter, its affiliates, directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Act and the Exchange Act for any legal or other expenses reasonably incurred by such Underwriter, its affiliates, directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Act and the Exchange Act in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that such Selling Stockholder shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is

20

based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, in reliance upon and in conformity with the Underwriter Information; provided, further, that the liability of such Selling Stockholder pursuant to this subsection (c) shall not exceed the product of the number of Shares sold by such Selling Stockholder including any Optional Shares and the price per Share referenced in Section 2 hereof (each such amount, the “Selling Stockholder Proceeds”) as set forth in the Prospectus.

(d) Each Underwriter will, severally and not jointly, indemnify and hold harmless the Company, its directors, officers and employees and each person, if any, who controls, as of the date hereof, the Company within the meaning of the Act and the Exchange Act and each Selling Stockholder against any losses, claims, damages or liabilities to which the Company, its directors, officers and employees and each person, if any, who controls, as of the date hereof, the Company within the meaning of the Act and the Exchange Act or such Selling Stockholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto, or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, or arise out of or are based upon the omission or alleged omission to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, in reliance upon and in conformity with the Underwriter Information; and will reimburse the Company, its directors, officers and employees and each person, if any, who controls, as of the date hereof, the Company within the meaning of the Act and the Exchange Act and each Selling Stockholder for any legal or other expenses reasonably incurred by the Company, its directors, officers and employees and each person, if any, who controls, as of the date hereof, the Company within the meaning of the Act and the Exchange Act or such Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred, it being understood and agreed that the only such information furnished by the Underwriters consists of the following information: (i) the names of the Underwriters appearing on the front and back cover pages of the Preliminary Prospectus and the Prospectus; (ii) the names of the Underwriters set forth in the table of Underwriters in the first paragraph of text under the caption “Underwriting” in the Preliminary Prospectus and the Prospectus; (iii) the third paragraph of text under the caption “Underwriting” in the Preliminary Prospectus and the Prospectus concerning the terms of offering by the Underwriters; and (iv) the ninth and tenth paragraphs of text under the caption “Underwriting” in the Preliminary Prospectus and the Prospectus concerning transactions that stabilize, maintain or otherwise affect the price of the Shares (such information, the “Underwriter Information”).

(e) Promptly after receipt by an indemnified party under subsection (a), (b), (c) or (d) of this Section 8 of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party

21

otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. It is understood that the indemnifying party or parties shall not, in connection with any one action or proceeding or separate but substantially similar actions or proceedings arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all indemnified parties except to the extent that local counsel or counsel with specialized expertise (in addition to any regular counsel) is required to effectively defend against any such action or proceeding. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

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

22

(even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (f). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (f) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (f), (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) each Selling Stockholder’s obligation to contribute any amount under this Section 8(f) is limited in the manner and to the extent set forth in Section 9(b) and such Selling Stockholder shall not be required to contribute any amount in excess of the applicable Selling Stockholder Proceeds. 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. The Underwriters’ obligations in this subsection (f) to contribute are several in proportion to their respective underwriting obligations and not joint, and the Selling Stockholders’ obligations in this subjection (f) to contribute are several in proportion to their respective Selling Stockholder Proceeds and not joint.

(g) The obligations of the Company and the Selling Stockholders under this Section 8 shall be in addition to any liability which the Company and the Selling Stockholders may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 8 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and to each person, if any, who controls the Company or any Selling Stockholder within the meaning of the Act.

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

23

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you, the Company and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Selling Stockholders shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you, the Company and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all of the Shares to be purchased at such Time of Delivery, or if the Selling Stockholders shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to a Second Time of Delivery, the obligations of the Underwriters to purchase and of the Selling Stockholders to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholders, except for the expenses to be borne by the Company, the Selling Stockholders and the Underwriters as provided in Section 8 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. The respective indemnities, rights of contribution, agreements, representations, warranties and other statements of the Company, or any Selling Stockholder, and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any of the Selling Stockholders, or any officer or director or controlling person of the Company, or any controlling person of any Selling Stockholder, and shall survive delivery of and payment for the Shares.

11. If this Agreement shall be terminated pursuant to Section 9 hereof, neither the Company nor the Selling Stockholders shall then be under any liability to any Underwriter except as provided in Sections 6 and 8 hereof; but, if for any other reason any Shares are not delivered by or on behalf of the Selling Stockholders as provided herein, each of the Selling Stockholders pro rata (based on the number of Shares to be sold by such Selling Stockholder hereunder) will reimburse the Underwriters through you for all reasonable and documented out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company and the Selling Stockholders shall then be under no further liability to any Underwriter except as provided in Sections 6 and 8 hereof.

12. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you; and in dealings with any Selling Stockholder hereunder, you and the Company shall be entitled to act and rely upon any statement, request, notice or agreement given by any Selling Stockholder.

24

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company and the Selling Stockholders, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to Citigroup Global Markets Inc., 388 Greenwich Street, New York, New York 10013, Attention: General Counsel, Facsimile Number: 1 ###-###-#### and to Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282, Attention: Registration Department; if to any Selling Stockholder shall be delivered or sent by mail, telex or facsimile transmission to counsel for such Selling Stockholder at its address set forth in Schedule V hereto; if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth on the cover of the Registration Statement, Attention: Michael-Bryant Hicks, Executive Vice President, General Counsel and Secretary; and if to any of the parties that has delivered a lock-up letter described in Section 7(k) hereof shall be delivered or sent by mail to the respective address provided in Schedule V hereto or such other address as such party provides in writing to the Company; provided, however, that any notice to an Underwriter pursuant to Section 8(e) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire or telex constituting such Questionnaire, which address will be supplied to the Company or the Selling Stockholders by you on request; provided further that notices under subsection 4(e) shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to you at Citigroup Global Markets Inc., 388 Greenwich Street, New York, New York 10013, Attention: General Counsel, Facsimile Number: 1 ###-###-#### and to Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282, Attention: Registration Department. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

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

14. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

15. The Company and the Selling Stockholders hereby acknowledge that (a) the purchase and sale of the Shares pursuant to this Agreement, including without limitation the determination of the public offering price of the Shares and any interaction that the Underwriters have with the Company, the Selling Stockholders and/or their respective representatives or agents in relation thereto, is part of an arm’s-length commercial transaction between the Company and the Selling Stockholders, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Company or the Selling Stockholders and (c) the Company’s and Selling Stockholders’ engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company and the Selling Stockholders agree that they are solely responsible for making their own judgments in connection with the offering and other matters

25

addressed herein or contemplated hereby (irrespective of whether any of the Underwriters has advised or is currently advising the Company or any Selling Stockholder on related or other matters). The Company and the Selling Stockholders also acknowledge and agree that the Underwriters have not rendered to them any investment advisory services of any nature or respect and will not claim that the Underwriters owe any agency, fiduciary or similar duty to the Company or any of the Selling Stockholders, in connection with the offering and such other matters or the process leading thereto. The Company further acknowledges and agrees that in any and all discussions with the Underwriters in connection with this Agreement and the matters contemplated hereby, that the Underwriters are providing services solely to the Company and all such employees, officers or directors of the Company engaged in such discussions are acting solely as representatives of the Company not in their individual or personal capacity as potential selling stockholders or as representatives of the Selling Stockholders (or any individual Selling Stockholder), and that any view expressed or recommendation that may be deemed to be made by the Underwriters is expressed or made solely to and for the benefit of the Company. The Selling Shareholder further acknowledges and agrees that, although the Underwriters may provide the Selling Shareholder with certain Regulation Best Interest and Form CRS disclosures or other related documentation in connection with the offering, the Underwriters are not making a recommendation to the Selling Shareholder to participate in the offering or sell any Shares at the Purchase Price, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

16. This Agreement supersedes all prior agreements and understandings (whether written or oral) between or among the Company, the Selling Stockholders and the Underwriters, or any of them, with respect to the subject matter hereof.

17. This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by and construed in accordance with the laws of the State of New York.

18. The Company and each Selling Stockholder agrees that any suit or proceeding arising in respect of this Agreement or our engagement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Company and each Selling Stockholder agree to submit to the jurisdiction of, and to venue in, such courts, and waive, to the fullest extent they may effectively do so, any objection which they may now or hereafter have to the laying of venue of any such proceeding.

19. The Company, each Selling Stockholder and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

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

21. Without limiting the applicability of Section 2 hereof or any other provision of this Agreement, with respect to any Underwriter who is affiliated with any person or entity engaged to act as an investment adviser on behalf of a client who has a direct or indirect interest in the Shares being sold by any Selling Stockholder, the Shares being sold to such Underwriter shall not include any shares of Stock attributable to such client (with any such Shares instead being allocated and sold to the other Underwriters) and, accordingly, the fees or other amounts received by such Underwriter in connection with the transactions contemplated hereby shall not include any fees or other amounts attributable to such client.

26

22. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

Ladies and Gentlemen:

The undersigned understands that Citigroup Global Markets Inc. and Goldman Sachs & Co.
