As used herein, the term “Notes” shall include the Guarantees, unless the context otherwise requires. This is to confirm the agreement concerning the purchase of the Notes from the Company by the Initial Purchasers.

The Notes will be offered and sold to the Initial Purchasers without registration under the Securities Act of 1933, as amended (the “Act”), in reliance on an exemption pursuant to Section 4(2) under the Act.

As used in this Agreement, “Applicable Time” means 5:00 P.M. (New York City time) on the date of this Agreement and “Pricing Disclosure Package” means, as of the Applicable Time, the Preliminary Offering Memorandum together with the Pricing Supplement.

As used in this Agreement, “Supplemental Offering Materials” means any “written communication” (within the meaning of the Act and the rules and regulations thereunder) prepared by or on behalf of the Company, or used or referred to by the Company, that that would reasonably be expected to constitute an offer to sell or a solicitation of an offer to buy the Notes other than the Pricing Disclosure Package and the Offering Memorandum or amendments or supplements thereto, including, without limitation, any road show relating to the Notes that would reasonably be expected to constitute such a written communication.

It is understood and acknowledged that upon original issuance thereof, and until such time as the same is no longer required under the applicable requirements of the Act, the Notes (and all securities issued in exchange therefor or in substitution thereof) shall bear the following legend (along with such other legends as the Initial Purchasers and their counsel or the Company and its counsel deem necessary):

The foregoing indemnity agreement is in addition to any liability that the Company or the Guarantors may otherwise have to any Initial Purchaser or to any director, officer, employee or controlling person of that Initial Purchaser.

(b) Each Initial Purchaser, severally and not jointly, hereby agrees to indemnify and hold harmless the Company, each Guarantor, their respective officers and employees, each of their respective directors, and each person, if any, who controls the Company or any Guarantor within the meaning of the Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, any Guarantor or any such director, officer, employee or controlling person may become subject, under the Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in the Pricing Disclosure Package, the Final Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky Application, or (C) in any Marketing Materials or (ii) the omission or alleged omission to state in the Pricing Disclosure Package, the Final Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the 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 or on behalf of that Initial Purchaser specifically for inclusion therein, and shall reimburse the Company, any Guarantor and any such director, officer, employee or controlling person for any legal or other expenses reasonably incurred by the Company, any Guarantor or any such director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability that any Initial

Purchaser may otherwise have to the Company, any Guarantor or any such director, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under this Section 8 except to the extent it has been materially prejudiced 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 this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Initial Purchasers shall have the right to employ counsel to represent jointly the Initial Purchasers and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Initial Purchasers against the Company or any Guarantor under this Section 8 if, in the reasonable judgment of the Initial Purchasers, it is advisable for the Initial Purchasers and those directors, officers, employees and controlling persons to be jointly represented by separate counsel, and in that event the fees and expenses of such separate counsel shall be paid by the Company or any Guarantor. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, and does not include any statement as to or any admission of fault, culpability or failure to act by or on behalf of any indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be

appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other, from the offering of the Notes 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 and the Guarantors, on the one hand, and the Initial Purchasers, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under this Agreement (before deducting expenses) received by the Company and the Guarantors on the one hand, and the total discounts and commissions received by the Initial Purchasers with respect to the Notes purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Notes under this Agreement. The relative fault shall be determined by reference to whether the 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 Guarantors or the Initial Purchasers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. For purposes of the preceding two sentences, the net proceeds deemed to be received by the Company shall be deemed to be also for the benefit of the Guarantors and information supplied by the Company shall also be deemed to have been supplied by the Guarantors. The Company, the Guarantors, and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), 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 Section 8(d), no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Notes exceeds the amount of any damages that such Initial Purchaser has otherwise paid or become liable to pay by reason of any 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Initial Purchasers severally confirm and the Company and the Guarantors acknowledge that the statements with respect to the offering of the Notes by the Initial Purchasers set forth on the second to last paragraph on the front cover of the Final Offering Memorandum and in the section entitled “Plan of Distribution” in the Offering Memorandum are correct and constitute the only information concerning such Initial Purchasers furnished in writing to the Company or any Guarantor by or on behalf of the Initial Purchasers specifically for inclusion in Preliminary Offering Memorandum or the Final Offering Memorandum.

9. Defaulting Initial Purchasers. If, on the Closing Date, any Initial Purchaser defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Initial Purchasers shall be obligated to purchase the Notes that the defaulting Initial Purchaser agreed but failed to purchase on the Closing Date in the respective proportions that the number of Notes set opposite the name of each remaining non-defaulting Initial Purchaser in Schedule I hereto bears to the total number of Notes set opposite the names of all the remaining non-defaulting Initial Purchasers in Schedule I hereto; provided, however, that the remaining non-defaulting Initial Purchasers shall not be obligated to purchase any of the Notes on the Closing Date if the total number of Notes that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on such date exceeds 9.09% of the total number of Notes to be purchased on the Closing Date, and any remaining non-defaulting Initial Purchasers shall not be obligated to purchase more than 110% of the number of Notes that it agreed to purchase on the Closing Date pursuant to the terms of Section 3. If the foregoing maximums are exceeded, the remaining non-defaulting Initial Purchasers, or those other Initial Purchasers reasonably satisfactory to the Initial Purchasers who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Notes to be purchased on the Closing Date. If the remaining Initial Purchasers or other Initial Purchasers reasonably satisfactory to the Initial Purchasers do not elect to purchase the Notes that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on the Closing Date, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser or the Company or the Guarantors, except that the Company and the Guarantors will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11.

Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company or any Guarantor for damages caused by its default. If other Initial Purchasers are obligated or agree to purchase the Notes of a defaulting or withdrawing Initial Purchaser, either the remaining Initial Purchasers or the Company may postpone the Closing Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Pricing Disclosure Package, the Final Offering Memorandum or in any other document or arrangement.

10. Termination. The obligations of the Initial Purchasers hereunder may be terminated by the Initial Purchasers by notice given to and received by the Company prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Sections 7(j) or 7(o) shall have occurred or if the Initial Purchasers shall decline to purchase the Notes for any reason permitted under this Agreement.

11. Reimbursement of Initial Purchasers’ Expenses. If the Company fails to tender the Notes for delivery to the Initial Purchasers by reason of any failure, refusal or inability on the part of the Company or any Guarantor to perform any agreement on their part to be performed, or because any other condition of the obligations hereunder required to be fulfilled by the Company or any Guarantor is not fulfilled, the Company and the Guarantors shall reimburse the Initial Purchasers for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) incurred by the Initial Purchasers in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Company and the Guarantors shall pay the full amount thereof to ▇▇▇▇▇▇ Brothers Inc. for the benefit of the Initial Purchasers.

12. Research Independence. The Company and the Guarantors acknowledge that the Initial Purchasers’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Initial Purchasers’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of its investment bankers. The Company and the Guarantors hereby waive and release, to the fullest extent permitted by law, any claims that the Company and/or any Guarantor may have against any 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 Company or any of the Guarantors by the investment banking division of any such Initial Purchaser. The Company and the Guarantors acknowledge that each of the Initial Purchasers 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.

13. No fiduciary duty. The Company and the Guarantors acknowledge and agree that in connection with this offering, sale of the Notes 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 Purchasers: (i) no fiduciary or agency relationship between the Company and/or any of the Guarantors and any other person, on the one hand, and the Initial Purchasers, on the other, exists; (ii) the Initial Purchasers are not acting as advisors, expert or otherwise, to the Company or any of the Guarantors in connection with the offering contemplated hereby, including, without limitation, with respect to the determination of the offering price of the Notes, and such relationship between the Company and/or any of the Guarantors, on the one hand, and the Initial Purchasers, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Initial Purchasers may have to the Company and/or any of the Guarantors shall be limited to those duties and obligations specifically stated herein; and (iv) the Initial Purchasers and their respective affiliates may have interests that differ from those of the Company and the Guarantors. The Company and the Guarantors hereby waive any claims that the Company and/or any of the Guarantors may have against the Initial Purchasers with respect to any breach of fiduciary duty in connection with the offering of the Notes.

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