Each of the Company and the Guarantors, jointly and severally, covenants and agrees with the Purchaser that it will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company's and the Bond Guarantor's counsel and accountants in connection with the issue of the Bonds and the Bond Guaranty and all other expenses in connection with the preparation, printing and filing of the Preliminary Offering Circular and the Offering Circular and any amendments and supplements thereto and the mailing and delivering of copies thereof to the Purchaser and dealers; (ii) the cost of printing or producing the Operative Agreements, the Blue Sky and Legal Investment Memoranda, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Bonds and the Guarantees; (iii) all expenses in connection with the qualification of the Bonds and the Guarantees for offering and sale under state securities laws as provided in Section 5(b) hereof, including the reasonable fees and disbursements of counsel for the Purchaser in connection with such qualification and in connection with the Blue Sky and legal investment surveys; (iv) any fees charged by securities rating services for rating the Bonds; (v) the cost of preparing the global Bonds and the Guarantees; (vi) the fees and expenses of the Trustee, the Collateral Agent and any agent of the Trustee and the Collateral Agent approved by the Company and the reasonable fees and disbursements of counsel for the Trustee and the Collateral Agent in connection with the Indenture and the Bonds and the Guarantees; (viii) any cost incurred in connection with the designation of the Bonds for trading in PORTAL and (ix) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section.

Conditions Precedent to the obligations of the Purchaser: (a) The obligations of the Purchaser hereunder shall be subject, in its discretion, to the condition that all representations and warranties and other statements of the Company and each of the Guarantors herein are, at and as of the Time of Delivery, true and correct, to the condition that the Company and each of the Guarantors shall have performed all of their respective obligations hereunder theretofore to be performed, and the following additional conditions: (b) Latham & Watkins, counsel for the Purchaser, shall have furnished to you such opinion or opinions, dated the Time of Delivery, in form and substance as set forth in Exhibit A hereto and with respect to such other related matters as you may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters; (c) Orrick, Herrington & Sutcliffe LLP (or, with respect to certain issues, other counsel satisfactory to you), counsel for the Company and the Guarantors, shall have furnished to you their written 12 opinion, dated the Time of Delivery, in form and substance as set forth in Exhibit B hereto and otherwise satisfactory to you; (d) Orrick, Herrington & Sutcliffe LLP, counsel for the Company and the Guarantors, shall have furnished to you their written tax opinion, dated the Time of Delivery, in form and substance as contained in Orrick, Herrington & Sutcliffe LLP's opinion set forth in Exhibit B hereto; (e) On the date of the Offering Circular prior to the execution of this Agreement and also at the Time of Delivery, each of Deloitte and Touche and Price Waterhouse LLP shall have furnished to you a letter or letters, dated the respective dates of delivery thereof, in form and substance satisfactory to you, to the effect set forth in Annex II hereto; (f) (i) None of the Company, the Bond Guarantor or the Partnerships or any of their subsidiaries shall have sustained since the date of the latest audited financial statements included in the Offering Circular 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 Offering Circular, and (ii) since the respective dates as of which information is given in the Offering Circular there shall not have been any change in the capital stock of the Company or long-term debt of the Company, the Bond Guarantor or the Partnerships or any of their respective subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, shareholders' equity or partners' equity interests, as applicable, or results of operations of it and its subsidiaries, otherwise than as set forth or contemplated in the Offering Circular, the effect of which, in any such case described in Clause (i) or (ii), is in the judgment of the Purchaser so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Bonds on the terms and in the manner contemplated in this Agreement and in the Offering Circular; (g) On or after the date hereof (A) (i) the ratings of the Bonds shall be at least "Ba1" by Moody's Investors Services, Inc.

(a) The Company and each of the Guarantors, collectively referred to herein as the "Indemnifying Parties" and each individually as the "Indemnifying Party") will, jointly and severally, indemnify and hold harmless the Purchaser against any losses, claims, damages or liabilities, joint or several, to which such 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 Offering Circular, 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 necessary to make the statements therein not misleading, and will reimburse the Purchaser for any legal or other expenses reasonably incurred by the Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company or the Guarantors 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 any Preliminary Offering Circular or the Offering Circular or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company or the Guarantors by the Purchaser expressly for use therein. (b) The Purchaser will indemnify and hold harmless the Indemnifying Parties against any losses, claims, damages or liabilities to which such Indemnifying Parties 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 Offering Circular or the Offering Circular, 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 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 any Preliminary Offering Circular or the Offering Circular or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Indemnifying Parties by the Purchaser expressly for use therein; and will reimburse the Indemnifying Parties for any legal or other expenses reasonably incurred by such Indemnifying Parties 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 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 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 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. 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 14 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. (d) If the indemnification provided for in this Section 8 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 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 Indemnifying Parties on the one hand and the Purchaser on the other from the offering of the Bonds. 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 (c) 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 Indemnifying Parties on the one hand and the 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 Indemnifying Parties on the one hand and the 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 Indemnifying Parties bear to the total underwriting discounts and commissions received by the Purchaser, in each case as set forth in the Offering Circular. 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 Indemnifying Parties on the one hand or the Purchaser on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Indemnifying Parties and the Purchaser agree that it would not be just and equitable if contribution 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 Purchaser shall not be required to contribute any amount in excess of the amount by which the total price at which the Bonds were offered to investors exceeds the amount of any damages which the 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 Indemnifying Parties under this Section 8 shall be in addition to any liability which the Indemnifying Parties may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Purchaser within the meaning of the Securities Act; and the obligations of the Purchaser under this Section 8 shall be in addition to any liability which the Purchaser may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Indemnifying Parties and to each person, if any, who controls any Indemnifying Parties within the meaning of the Securities Act. 9. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Guarantors and the Purchaser, as set forth in this Agreement or made by 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 the Purchaser or any controlling person of the Purchaser, or any of the Company or the Guarantors, or any officer or director or controlling person thereof, and shall survive delivery of and payment for the Bonds. 15 10. If for any other reason, the Bonds are not delivered by or on behalf of the Company as provided herein, the Company and each of the Guarantors, jointly and severally, will reimburse you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by you in making preparations for the purchase, sale and delivery of the Bonds, but the Company and the Guarantors shall then be under no further liability to you except as provided in Sections 6 and 8 hereof. 11. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Initial Purchaser shall be delivered or sent by mail, telex or facsimile transmission to you at 85 Broad Street, New York, New York 10004, Attention: Registration Department; and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Offering Circular, Attention: Secretary. 12. This Agreement shall be binding upon, and inure solely to the benefit of the Purchaser, the Company and the Guarantors and, to the extent provided in Sections 8 and 10 hereof, the officers and directors thereof and each person who controls any of the Company, the Guarantors, or the Purchaser, 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 Bonds from the Purchaser shall be deemed a successor or assign by reason merely of such purchase. 13. Time shall be of the essence of this Agreement. 14. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 15. 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 respective counterparts shall together constitute one and the same instrument. [Signature page follows] 16 If the foregoing is in accordance with your understanding, please sign and return to us (one for each of the Company, the Bond Guarantor, each Sponsor Guarantor and the Purchaser plus one for each counsel) counterparts hereof, and upon the acceptance hereof by you, this letter and such acceptance hereof shall constitute a binding agreement between you and each of the Company, the Bond Guarantors and the Sponsor Guarantors.

The Purchaser represents that it has offered and sold the Bonds and will offer and sell the Bonds (i) as part of its distribution at any time and (ii) otherwise until 40 days after the later of the commencement of the offering and the Time of Delivery, only in accordance with Rule 903 of Regulation S or the Rule 144A under the Securities Act. Accordingly, the Purchaser agrees that neither it, its affiliates nor any persons acting on its behalf has engaged or will engage in any directed selling efforts with respect to the Bonds, and it and they have complied and will comply with the offering restrictions requirement of Regulation S. The Purchaser agrees that, at or prior to confirmation of sale of Bonds (other than a sale pursuant to Rule 144A) it will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Bonds from it during the restricted period a confirmation or notice to substantially the following effect: "The Bonds covered hereby have not been registered under the U.S. Securities Act of 1933 (the "Securities Act") and may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the offering and the closing date, except in either case in accordance with Regulation S (or Rule 144A if available) under the Securities Act. Terms used above have the meaning given to them by Regulation S." Terms used in this paragraph have the meanings given to them by Regulation S. The Purchaser further agrees that it has not entered and will not enter into any contractual arrangement with respect to the distribution or delivery of the Bonds except with its affiliates or with the prior written consent of the Company. In addition, (A) except to the extent permitted under U.S. Treas. Reg. ss. 1.163-5(C)(2)(i)(D) (the "D Rules"), (i) the Purchaser agrees that it has not offered or sold, and during the restricted period will not offer or sell, Bonds in bearer form to a person who is within the United States or its possessions or to a U.S. person, and (ii) it has not delivered and will not deliver within the United States or its possessions definitive Bonds in bearer form that are sold during the restricted period; (B) the Purchaser represents and agrees that it has, and throughout the restricted period will have, in effect procedures reasonably designed to ensure that its employees or agents who are directly engaged in selling Bonds in bearer form are aware that such Bonds may not be offered or sold during the restricted period to a person who is within the United States or its possessions or to a United States person, except as permitted by the D Rules; (C) if it is a United States person, the Purchaser represents that it is acquiring the Bonds in bearer form for purposes of resale in connection with their original issuance and if it retains Bonds in A-4 bearer form for its own account, it will only do so in accordance with the requirements of U.S. Treas. Reg. ss. 1.163-5(c)(2)(i)(D)(6); and (D) with respect to each affiliate that acquires from it Bonds in bearer form for the purpose of offering or selling such Bonds during the restricted period, the Purchaser either (i) repeats and confirms the representations and agreements contained in clauses (A), (B) and (C) on its behalf or (ii) agrees that it will obtain from such affiliate for the Company's benefit the representations and agreements contained in clauses (A), (B) and (C). Terms used in this paragraph have the meanings given to them by the United States Internal Revenue Code and regulations thereunder, including the D Rules. (2) Notwithstanding the foregoing, Bonds in registered form may be offered, sold and delivered by the Purchaser in the United States and to U.S. persons pursuant to Section 3 of this Agreement without delivery of the written statement required by paragraph (1) above. (3) The Purchaser further represents and agrees, on behalf of itself and its affiliates, that (i) it has not offered or sold and prior to the date six months after the date of issue of the Bonds will not offer or sell any Bonds to persons in the United Kingdom except to persons whose ordinary activities involve them in acquiring, holding, managing or disposing of investments (as principal or agent) for the purposes of their businesses or otherwise in circumstances which have not resulted and will not result in an offer to the public in the United Kingdom within the meaning of the Public Offers of Securities Regulations 1995, (b) it has complied, and will comply, with all applicable provisions of the Financial Services Act of 1986 of Great Britain with respect to anything done by it in relation to the Bonds in, from or otherwise involving the United Kingdom, and (C) it has only issued or passed on and will only issue or pass on in the United Kingdom any document received by it in connection with the issuance of the Bonds to a person who is of a kind described in Article 11(3) of the Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order 1996 of Great Britain or is a person to whom the document may otherwise lawfully be issued or passed on. (4) The Purchaser agrees that it will not offer, sell or deliver any of the Bonds in any jurisdiction outside the United States except under circumstances that will result in compliance with the applicable laws thereof, and that it will take at its own expense whatever action is required to permit its purchase and resale of the Bonds in such jurisdictions. The Purchaser understands that no action has been taken to permit a public offering in any jurisdiction outside the United States where action would be required for such purpose. The Purchaser agrees not to cause any advertisement of the Bonds to be published in any newspaper or periodical or posted in any public place and not to issue any circular relating to the Bonds, except in any such case with Goldman, Sachs & Co.'s express written consent and then only at its own risk and expense.
