It is understood, however, that except as provided in this Section, Section 7 entitled “Indemnity and Contribution,” and Section 9 below, the Initial Purchaser will pay all of its costs and expenses, including fees and disbursements of its counsel, transfer taxes payable on resale of any of the Securities by it and any advertising expenses connected with any offers it may make.

(o) During the period beginning on the date hereof and continuing to and including the Closing Date, not to offer, sell, contract to sell or otherwise dispose of any debt securities of the Company or warrants to purchase or otherwise acquire debt securities of the Company substantially similar to the Securities (other than (i) the Securities, (ii) commercial paper issued in the ordinary course of business or (iii) securities or warrants permitted with the prior written consent of the Initial Purchaser, provided that nothing in this paragraph (l) shall be construed as a limitation on the Company’s ability to consummate, or

prevent the Company from consummating the transactions as described in the Disclosure Package and the Final Memorandum under the heading “The Transactions.”

7. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless the Initial Purchaser, each person, if any, who controls the Initial Purchaser within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act and each affiliate of the Initial Purchaser from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in any preliminary memorandum, the Disclosure Package, any Issuer Written Information that the Company has used or referred to in connection with the Act or the Final Memorandum or any amendment or supplement thereto (if the Company furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, (i) with respect to any preliminary memorandum, the Disclosure Package, any Issuer Written Information that the Company has used or referred to in connection with the Act or the Final Memorandum or any amendment or supplement thereto (if the Company furnished any amendments or supplements thereto), not misleading in light of the circumstances under which they were made, except in each case insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Initial Purchaser furnished to the Company in writing by the Initial Purchaser expressly for use therein.

(b) The Initial Purchaser agrees to indemnify and hold harmless the Company, its directors, its principal executive officer or officers, its principal financial officer, its controller or principal accounting officer, and each person if any, who controls the Company within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to the Initial Purchaser, but only with reference to information relating to the Initial Purchaser furnished to the Company in writing by the Initial Purchaser expressly for use in the any preliminary prospectus, the Disclosure Package, any Issuer Written Information that the Company has used or referred to in connection with the Act or the Final Memorandum or any amendment or supplement thereto. The Company acknowledges that the statement set forth on the cover of the Final Memorandum that “The initial purchaser expects to deliver book-entry interests in the notes to purchasers on or about January 26, 2011 through the facilities of The Depository Trust Company (“DTC”),” and the statements in the Preliminary Memorandum and the Final Memorandum in the second and eleventh paragraphs under the caption “Plan of Distribution” and in the fourth and fifth sentence of the ninth paragraph under the

caption “Plan of Distribution” related to the terms of the offering, short sales, stabilization and syndicate covering transactions constitute the only information furnished in writing by or on behalf of the Initial Purchaser for inclusion in the Preliminary Memorandum or the Final Memorandum or in any amendment or supplement thereto.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 7(a) or 7(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel chosen by the indemnifying party and reasonably satisfactory to the indemnified party to represent the indemnified party and any others entitled to indemnification pursuant to this section 7 the indemnifying party may designate in such proceeding and shall pay the reasonably incurred fees and expenses of such counsel related to such proceeding as incurred. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the reasonably incurred fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonably incurred fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such reasonably incurred fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Initial Purchaser in the case of parties indemnified pursuant to Section 7(a), and by the Company, in the case of parties indemnified pursuant to Section 7(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding 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 an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) To the extent the indemnification provided for in Section 7(a) or Section 7(b) is unavailable to an indemnified party or insufficient in respect of

any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 7(d)(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 7(d)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that 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 hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of Securities and the total underwriting discounts and commissions received by the Initial Purchaser in connection therewith, bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and the Initial Purchaser on the other hand 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 by the Initial Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company and the Initial Purchaser agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 7(d) shall be deemed to include, subject to the limitations set forth above, 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 7, the Initial Purchaser shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 7 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchaser, any person controlling the Initial Purchaser or any affiliate of the Initial Purchaser or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

8. Termination. The Initial Purchaser may terminate this Agreement by notice given by the Initial Purchaser to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange or the Nasdaq National Market, (ii) trading of any securities of the Company shall have been suspended on the New York Stock Exchange, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Initial Purchaser’s judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Disclosure Package or the Final Memorandum.

9. Effectiveness; Defaulting Initial Purchaser. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto. If this Agreement shall be terminated by the Initial Purchaser because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement the Company will reimburse the Initial Purchaser for all out of pocket expenses (including the reasonable fees and disbursements of their counsel) reasonably incurred by the Initial Purchaser in connection with this Agreement or the offering contemplated hereunder.

10. Waiver of Tax Confidentiality. Notwithstanding anything herein to the contrary, purchasers of the Securities (and each employee, representative or other agent of a purchaser) may disclose to any and all persons, without limitation of any kind, the U.S. tax treatment and U.S. tax structure of any transaction contemplated herein and all materials of any kind (including opinions or other tax analyses) that are provided to the purchasers of the Securities relating to such U.S. tax treatment and U.S tax structure, other than any information for which

nondisclosure is reasonably necessary in order to comply with applicable securities laws.

11. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Securities, represents the entire agreement between the Company and the Initial Purchaser with respect to the preparation of any preliminary memorandum, the Disclosure Package, the Final Memorandum, the conduct of the offering, and the purchase and sale of the Securities.

(b) The Company acknowledges that in connection with the offering of the Securities: (i) the Initial Purchaser has acted at arms length, is not an agent of, and owes no fiduciary duties to, the Company or any other person, (ii) the Initial Purchaser owes the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Initial Purchaser may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Initial Purchaser arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

12. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

13. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

	We expect that delivery of the notes will be made against payment therefor on or about the tenth business day following the date of confirmation of orders with respect to the notes (this settlement cycle being referred to as “T+10”). Under Rule 15c6-1 of the Commission under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes before the notes are delivered will be required, by virtue of the fact that the notes initially will settle in T+10, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes before their delivery should consult their own advisor.
