8. Effective Date of Agreement.

This Agreement shall become effective upon the execution hereof by the parties hereto.

9. Indemnification and Contribution.

(a) The Transaction Entities, jointly and severally, will indemnify and hold harmless the Initial Purchaser against any losses, claims, damages or liabilities, joint or several, to which the Initial Purchaser may become subject, under the Securities 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 Preliminary Memorandum or the Final Memorandum as amended or supplemented or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made not misleading, and will reimburse the Initial Purchaser for any legal or other expenses reasonably incurred by the Initial Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that none of the Transaction Entities shall be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Memorandum and the Final Memorandum as amended or supplemented or any such amendment or supplement, in reliance upon and in conformity with written information furnished to the Transaction Entities by the Initial Purchaser expressly for use therein, which information is set forth in Exhibit A hereto.

(b) The Initial Purchaser will indemnify and hold harmless each of the Transaction Entities against any losses, claims, damages or liabilities to which such Transaction Entity may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Memorandum and the Final Memorandum as amended or supplemented, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are 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 any Preliminary Memorandum and the Final Memorandum as amended or supplemented, or any such amendment or supplement in reliance upon and in conformity with written information furnished to such Transaction Entity by the Initial Purchaser expressly for use therein, which information is set forth in Exhibit A hereto; and will reimburse the Transaction Entities for any legal or other expenses reasonably incurred by the Transaction Entities in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify such indemnifying party shall not relieve it from any liability which it may have to any indemnified party under such subsection except to the extent it has been materially prejudiced by such failure. 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 or other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding the indemnifying party’s election to appoint 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, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the

indemnifying party, (iii) the indemnifying party shall not have employed counsel 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. 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 any statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party in respect of such losses, claims, damages or liabilities (or actions in respect thereto), 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 Transaction Entities on the one hand and the Initial Purchaser on the other from the offering of the Shares to which such loss, claim, damage or liability (or action in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, 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 Transaction Entities on the one hand and the Initial Purchaser 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 Transaction Entities on the one hand and the Initial Purchaser on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Transaction Entities bear to the total underwriting discounts and commissions received by the Initial Purchaser. The relative fault shall be determined by reference, 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 Transaction Entities on the one hand or the Initial Purchaser on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Transaction Entities and the Initial Purchaser agree that it would not be just and equitable if contributions pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), the Initial Purchaser shall not be required to contribute any amount in excess of the amount by which the total price at which the applicable Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The indemnifying party shall not be required to indemnify the indemnified party for any amount paid or payable by the indemnified party in the settlement of any action, proceeding or investigation without the written consent of the indemnifying party, which consent shall not be unreasonably withheld.

(e) The obligations of the Transaction Entities under this Section 9 shall be in addition to any liability which the Transaction Entities may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Initial Purchaser within the meaning of the Securities Act; and the obligations of the Initial Purchaser under this Section 9 shall be in addition to any liability which the Initial Purchaser may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Transaction Entities and to each person, if any, who controls the Transaction Entities within the meaning of the Securities Act.

10. Termination. The obligations of the Initial Purchaser hereunder may be terminated by notice given to and received by the Company prior to delivery of and payment for the Shares if, prior to that time, any of the following events shall have occurred or if the Initial Purchaser shall decline to purchase the Shares for any reason permitted under this Agreement:

(a) (i) Any of the Transaction Entities or any Property shall have sustained, since the date of the latest financial statements included in the Disclosure Package and the Final Memorandum, any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Final Memorandum or (ii) since the date of the latest financial statements included in the Disclosure Package and the Final Memorandum there shall have been any change in the capital stock or long-term debt of any Transaction Entity or any change, or any development involving a prospective change, in or affecting any Property or the general affairs, management, financial position, stockholders’ equity or results of operations of any Transaction Entity, otherwise than as set forth or contemplated in the Disclosure Package and the Final Memorandum, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Initial Purchaser, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares being delivered on the Closing Date on the terms and in the manner contemplated in the Disclosure Package and the Final Memorandum;

(b) Subsequent to the execution and delivery of this Agreement there shall have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange or the American Stock Exchange or in the over-the-counter market, or trading in any securities of the Company on any exchange or in the over-the-counter market, shall have been suspended or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by Federal or New York state authorities, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States, or (iv) there shall have occurred any other calamity or crisis or any change in general economic, political or financial conditions (or the effect of international conditions on the financial markets in the United States shall be such) as to make it, in the sole judgment of the Initial Purchaser impracticable or inadvisable to proceed with the public offering or delivery of the Shares being delivered on the Closing Date on the terms and in the manner contemplated in the Disclosure Package and the Final Memorandum; or

(c) The Transaction Entities shall have failed at or prior to the Closing Date to have performed or complied with any of their agreements herein contained and required to be performed or complied with by them hereunder at or prior to the Closing Date.

11. Reimbursement of Initial Purchaser’s Expenses. If (a) the Company shall fail to tender the Shares for delivery to the Initial Purchaser by reason of any failure, refusal or inability on the part of the Transaction Entities to perform any agreement on their part to be performed, or because any condition specified in Sections 10(a) or (c) hereof required to be fulfilled by the Transaction Entities is not fulfilled, the Transaction Entities will reimburse the Initial Purchaser for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) incurred by the Initial Purchaser in connection with this Agreement and the proposed purchase of the Shares, and upon demand the Transaction Entities shall pay the full amount thereof to the Initial Purchaser.

12. No Fiduciary Obligation. The Transaction Entities acknowledge and agree that in connection with this offering, sale of the Shares or any other services the Initial Purchaser may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Initial Purchaser: (i) no fiduciary or agency relationship between the Transaction Entities and any other person, on the one hand, and the Initial Purchaser, on the other, exists with respect to the offering of the Shares or the transactions contemplated by this Agreement; (ii) the Initial Purchaser is not acting as advisor, expert or otherwise, to the Transaction Entities including, without limitation, with respect to the determination of the public offering price of the Shares, and such relationship between the Transaction Entities, on the one hand, and the Initial Purchaser, on the other with respect to the offering of the Shares or the transactions contemplated by this Agreement, is entirely and solely commercial,

based on arms-length negotiations; (iii) any duties and obligations that the Initial Purchaser may have to the Transaction Entities shall be limited to those duties and obligations specifically stated herein; and (iv) the Initial Purchaser and its affiliates may have interests that differ from those of the Transaction Entities. The Transaction Entities hereby waive any claims that the Transaction Entities may have against the Initial Purchaser with respect to any breach of fiduciary duty in connection with the offering of the Shares or the transactions contemplated by this Agreement.

13. Research Analyst Independence. The Transaction Entities acknowledge that the Initial Purchaser’s research analysts and research departments are required to be independent from its investment banking divisions and are subject to certain regulations and internal policies, and that such Initial Purchaser’s research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Transaction Entities and/or the offering of the Shares that differ from the views of its investment banking divisions. The Transaction Entities hereby waive and release, to the fullest extent permitted by law, any claims that the Transaction Entities may have against the Initial Purchaser with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Transaction Entities by such Initial Purchaser’s investment banking divisions. The Transaction Entities acknowledge that the Initial Purchaser is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies which may be the subject of the transactions contemplated by this Agreement.

14. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

(a) if to the Initial Purchaser, shall be delivered or sent by mail, telex or facsimile transmission to Citigroup Global Markets Inc., 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: General Counsel (Fax: (000) 000-0000).

15. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Initial Purchaser, the Transaction Entities, and their respective personal representatives and successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (a) the representations, warranties, indemnities and agreements of the Transaction Entities contained in this Agreement shall also be deemed to be for the benefit of directors and officers of the Initial Purchaser and any person or persons, if any, who control the Initial Purchaser within the meaning of Section 15 of the Securities Act and (b) the indemnity agreement of the Initial Purchaser contained in Section 9(b) of this Agreement shall be deemed to be for the benefit of any person controlling the Transaction Entities within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 15, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

16. Survival. The respective indemnities, representations, warranties and agreements of the Transaction Entities and the Initial Purchaser contained in this Agreement or made by or on behalf on them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Shares and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them.

17. Definition of the Terms “Business Day” and “subsidiary”. For purposes of this Agreement, (a) ”business day” means any day on which the New York Stock Exchange, Inc. is open for trading and (b) ”subsidiary” has the meaning set forth in Rule 405 of the Securities Act Regulations.

18. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of New York.
