The United States Securities Act of 1933 is herein referred to as the “Securities Act.”

The sale of the Offered Securities to the Initial Purchaser will be made without registration of the Offered Securities under the Securities Act in reliance upon exemptions from the registration requirements of the Securities Act.

The Company hereby agrees with the Initial Purchaser as follows:

2. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, the Initial Purchaser that:

(a) A preliminary offering memorandum, dated September 9, 2008, (the “Preliminary Offering Memorandum”) relating to the Offered Securities to be offered by the Initial Purchaser and a final offering memorandum (the “Final Offering Memorandum”) disclosing the offering price and other final terms of the Offered Securities and is dated as of the date of this Agreement (even if finalized and issued subsequent to the date of this Agreement) have been or will be prepared by the Company. “General Disclosure Package” means the Preliminary Offering Memorandum, together with any Issuer Free Writing Communication (as hereinafter defined) existing at the Applicable Time (as

hereinafter defined) and the information in it which is intended for general distribution to prospective investors, as evidenced by its being specified in Schedule A to this Agreement (including the term sheet listing the final terms of the Offered Securities and their offering, included in Schedule A to this Agreement, which is referred to as the “Terms Communication”). “Applicable Time” means 6:00 p.m. (Eastern time) on the date of this Agreement. As of the date of this Agreement and as of the Closing Date, the Final Offering Memorandum does not, and will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. At the Applicable Time and as of the Closing Date, neither (i) the General Disclosure Package, nor (ii) any individual Supplemental Marketing Material (as hereinafter defined), when considered together with the General Disclosure Package, included nor will include any untrue statement of a material fact or omitted or will omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding two sentences do not apply to statements in or omissions from the Preliminary Offering Memorandum or Final Offering Memorandum, the General Disclosure Package or any Supplemental Marketing Material based upon written information furnished to the Company by the Initial Purchaser specifically for use therein, it being understood and agreed that the only such information is that described as such in Section 8(b) hereof. The information required to be delivered to holders and prospective purchasers of the Offered Securities pursuant to Section 4.03 of the Indenture and in accordance with Rule 144A(d)(4) under the Securities Act (the “Additional Issuer Information”) does not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Preliminary Offering Memorandum or Final Offering Memorandum based upon written information furnished to the Initial Purchaser specifically for use therein, it being understood and agreed that the only such information is that described as such in Section 8(b) hereof.

“Free Writing Communication” means a written communication (as such term is defined in Rule 405 under the Securities Act) that constitutes an offer to sell or a solicitation of an offer to buy the Offered Securities and is made by means other than the Preliminary Offering Memorandum or the Final Offering Memorandum. “Issuer Free Writing Communication” means a Free Writing Communication prepared by or on behalf of the Company, used or referred to by the Company or containing a description of the final terms of the Offered Securities or of their offering, in the form retained in the Company’s records. “Supplemental Marketing Material” means any Issuer Free Writing Communication specified in Schedule B to this Agreement.

(c) The Indenture has been duly authorized, executed and delivered in accordance with its terms by the Company, and conforms in all material respects to the description thereof contained in the General Disclosure Package and the Final Offering Memorandum and constitutes a valid and legally binding agreement of the Company enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

(b) The Initial Purchaser will indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or 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 any untrue statement or alleged untrue statement of any material fact contained in the Preliminary Offering Memorandum or the Final Offering Memorandum, in each case as amended or supplemented, or any Supplemental Marketing Material or any Issuer Free Writing Communication or arise out of or are based upon the omission or the alleged omission to state therein 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 reliance upon and in conformity with written information furnished to the Company by the Initial Purchaser specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by the Initial Purchaser consists of the following information in the Preliminary Offering Memorandum and the Final Offering Memorandum furnished on behalf of the Initial Purchaser: the fourth sentence in the paragraph under “Risk Factors – Risks Relating to this Offering and the Notes – Your ability to resell the notes may be limited by a number of factors; prices for the notes may be volatile”, the first sentence in the third paragraph under the caption “Plan of Distribution”, the seventh paragraph, the fourth sentence of the eighth paragraph and the ninth paragraph under the caption “Plan of Distribution”; provided, however, that the Initial Purchaser shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Company’s failure to perform its obligations under Section 5(a) of this Agreement.

(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (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 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 will not be liable to such indemnified party under this Section for any legal or other expenses

subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. It is understood and agreed that the indemnifying party shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any reasonably necessary local counsel) for the Company or the Initial Purchaser, as applicable, and that all such reasonable fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for the Initial Purchaser shall be designated in writing by the Initial Purchaser, and any such separate firm for the Company shall be designated in writing by the Company.

No indemnifying party shall, without the prior written consent of the indemnified party, which consent shall not be unreasonably withheld or delayed, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes (i) an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchaser on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above 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 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 as well as any other relevant equitable considerations. The relative benefits received by the Company 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 the offering (before deducting expenses) received by the Company from the sale of the Offered Securities, on the one hand, bear to the total discounts and commissions received by the Initial Purchaser from the Company in connection

therewith as provided under this Agreement, on the other hand. 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 Initial Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of 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 action or claim which is the subject of this subsection (d). 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 discounts, fees and commissions received by the Initial Purchaser 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.

(e) The obligations of the Company under this Section shall be in addition to any liability which the Company 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 or the Exchange Act; and the obligations of the Initial Purchaser under this Section 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 person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act.

The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the Initial Purchaser set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Initial Purchaser, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 9 or if for any reason the purchase of the Offered Securities by the Initial Purchaser is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company and the Initial Purchaser pursuant to Section 8 shall remain in effect. If the purchase of the Offered Securities by the Initial Purchaser is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 or the occurrence of any event specified in clause (iii), (iv), (vi), (vii) or (viii) of Section 7(b), the Company will reimburse the Initial Purchaser for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.
