Terms used in this Section 9 and not defined in this Agreement have the meanings given to them in Regulation S.

Section 10. Indemnification and Contribution.

(a) Each of the Company and the Guarantors jointly and severally agree to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees, Affiliates and agents of each Initial Purchaser and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any 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 any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon the following:

(i) any untrue statement or alleged untrue statement of any material fact contained in the Pricing Disclosure Package, any Issuer Written Communication or Final Memorandum or any amendment or supplement thereto; or

(ii) the omission or alleged omission to state, in the Pricing Disclosure Package, any Issuer Written Communication or the Final Memorandum or any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading;

and will reimburse, as incurred, the Initial Purchasers and each such controlling person for any legal or other expenses incurred by the Initial Purchasers or such controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, the Company and the Guarantors 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 untrue statement or alleged untrue statement or omission or alleged omission made in the Pricing Disclosure Package or Final Memorandum or any amendment or supplement thereto in reliance upon and in conformity with written information concerning the Initial Purchasers furnished to the Company by the Initial Purchasers through the

-23-

Representatives specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Initial Purchaser consists of the information described as such in Section 13 hereof. The indemnity provided for in this Section 10 will be in addition to any liability that the Company and the Guarantors may otherwise have to the indemnified parties. The Company and the Guarantors shall not be liable under this Section 10 for any settlement of any claim or action effected without its prior written consent, which shall not be unreasonably withheld, conditioned or delayed.

(b) Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold harmless the Company, each of the Guarantors and their respective directors, its officers and each person, if any, who controls the Company or any of the Guarantors within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company, any of the Guarantors or any such director, officer or controlling person may become subject under the Act, the Exchange Act 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 any material fact contained in the Pricing Disclosure Package or Final Memorandum or any amendment or supplement thereto, or (ii) the omission or the alleged omission to state therein a material fact required to be stated in the Pricing Disclosure Package or Final Memorandum or any amendment or supplement thereto, or necessary to make the statements therein 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 reliance upon and in conformity with written information concerning such Initial Purchaser, furnished to the Company by the Initial Purchasers through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Initial Purchaser consists of the information described as such in Section 13 hereof; and subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses incurred by the Company, any of the Guarantors or any such director, officer or controlling person in connection with investigating or defending against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action in respect thereof. The indemnity provided for in this Section 10 will be in addition to any liability that the Initial Purchasers may otherwise have to the indemnified parties. The Initial Purchasers shall not be liable under this Section 10 for any settlement of any claim or action effected without their consent, which shall not be unreasonably withheld.

(c) Promptly after receipt by an indemnified party under this Section 10 of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section 10, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve it from any 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 and 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 paragraphs (a) or (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel (including

-24-

local counsel) satisfactory to such indemnified party; provided, however, that if (i) the use of counsel (including local 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 one or more 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 receipt by the indemnifying party of notice of the institution of such action, or (iv) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party, then, in each such case, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel (including local counsel) to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 10 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Initial Purchasers in the case of paragraph (a) of this Section 10 or the Company and the Guarantors in the case of paragraph (b) of this Section 10, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions). All fees and expenses reimbursed pursuant to this paragraph (c) shall be reimbursed as they are incurred. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld, conditioned or delayed), unless such indemnified party waived in writing its rights under this Section 10, in which case the indemnified party may effect such a settlement without such consent. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party, or indemnity could have been sought hereunder by any indemnified party, unless such settlement (A) includes an unconditional written release of the indemnified party, in form and substance reasonably satisfactory to the indemnified party, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 10 is unavailable to, or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims,

-25-

damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Notes or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Company and the Guarantors on the one hand and any Initial Purchaser on the other shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting expenses) received by the Company and the Guarantors bear to the total discounts and commissions received by such Initial Purchaser. The relative fault of the parties 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 and the Guarantors on the one hand, or such Initial Purchaser on the other, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the circumstances. The Company, each of the Guarantors and the Initial Purchasers agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). Notwithstanding any other provision of this paragraph (d), no Initial Purchaser shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact, and 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. For purposes of this paragraph (d), each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Initial Purchasers, and each director of the Company and the Guarantors, each officer of the Company and the Guarantors and each person, if any, who controls the Company or any of the Guarantors within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company and the Guarantors.

Section 11. Survival Clause. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Company, the Guarantors, their respective officers and the Initial Purchasers set forth in this Agreement or made by or on behalf of them pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Company, the Guarantors, any of their respective officers or directors, the Initial Purchasers or any controlling person referred to in Section 10 hereof and (ii) delivery of and payment for the Notes. The respective agreements, covenants, indemnities and other statements set forth in Sections 6, 10, 11 and 16 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement.

-26-

Section 12. Termination.

(a) This Agreement may be terminated in the sole discretion of the Initial Purchasers by notice to the Company given prior to the Closing Date in the event that the Company shall have failed, refused or been unable to perform all obligations and satisfy all conditions on its part to be performed or satisfied hereunder at or prior thereto or, if at or prior to the Closing Date,

(i) any of the Company or the Subsidiaries shall have sustained any loss or interference with respect to its businesses or properties from fire, flood, hurricane, accident or other calamity, whether or not covered by insurance, or from any strike, labor dispute, slow down or work stoppage or any legal or governmental proceeding, which loss or interference, in the sole judgment of the Initial Purchasers, has had or has a Material Adverse Effect, or there shall have been, in the sole judgment of the Initial Purchasers, any event or development that, individually or in the aggregate, has or could be reasonably likely to have a Material Adverse Effect (including without limitation a change in control of the Company or the Subsidiaries), except in each case as described in the Pricing Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto);

(ii) trading in securities of the Company or in securities generally on the New York Stock Exchange, American Stock Exchange or the NASDAQ Global Market shall have been suspended or materially limited or minimum or maximum prices shall have been established on any such exchange or market;

(iii) a banking moratorium shall have been declared by New York or United States authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States;

(iv) there shall have been (A) an outbreak or escalation of hostilities between the United States and any foreign power (other than as in existence on the date hereof), or (B) an outbreak or escalation of any other insurrection or armed conflict involving the United States or any other national or international calamity or emergency, or (C) any material change in the financial markets of the United States which, in the case of (A), (B) or (C) above and in the sole judgment of the Initial Purchasers, makes it impracticable or inadvisable to proceed with the offering or the delivery of the Notes as contemplated by the Pricing Disclosure Package and the Final Memorandum; or

(v) any securities of the Company shall have been downgraded by any nationally recognized statistical rating organization or any such organization shall have publicly announced that it has under surveillance or review, or has changed its outlook with respect to, its ratings of any securities of the Company (other than an announcement with positive implications of a possible upgrading).

(b) Termination of this Agreement pursuant to this Section 12 shall be without liability of any party to any other party except as provided in Section 11 hereof.

-27-

Section 13. Information Supplied by the Initial Purchasers. The statements set forth in the last paragraph on the front cover page (as such paragraph is supplemented by the first item on Annex A) and in the eighth paragraph under the heading “Private Placement” in the Preliminary Memorandum and the Final Memorandum (to the extent such statements relate to the Initial Purchasers) constitute the only information furnished by the Initial Purchasers to the Company for the purposes of Sections 2(a) and 10 hereof.

Section 14. Notices.

All such notices and communications shall be deemed to have been duly given: when delivered by hand, if personally delivered; five business days after being deposited in the mail, postage prepaid, if mailed; and one business day after being timely delivered to a next-day air courier.

Section 15. Successors. This Agreement shall inure to the benefit of and be binding upon the Initial Purchasers, the Company and the Guarantors and their respective successors and legal representatives, and nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provisions herein contained; this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of such persons and for the benefit of no other person except that (i) the indemnities of the Company and the Guarantors contained in Section 10 of this Agreement shall also be for the benefit of any person or persons who control the Initial Purchasers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and (ii) the indemnities of the Initial Purchasers contained in Section 10 of this Agreement shall also be for the benefit of the directors of the Company, the Guarantors, their respective officers and any person or persons who control the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act. No purchaser of Notes from the Initial Purchasers will be deemed a successor because of such purchase.
