The Securities will be issued pursuant to the Indenture, to be dated as of the Closing Date (as defined in Section 2(c)) (as the same may be amended, supplemented, waived or otherwise modified from time to time in accordance with the terms thereof, the “Indenture”), among the Company, the Parent and U.S. Bank National Association, as trustee (the “Trustee”) and will be guaranteed on an unsecured senior basis by the Parent (the “Parent Guarantee”).

All opinions, letters, certificates and evidence mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Initial Purchasers.

7. Indemnification and Contribution.

(a) Indemnification of the Initial Purchasers. Each of the Company and the Parent jointly and severally agrees to indemnify and hold harmless each Initial Purchaser, their respective affiliates, directors and officers and each person, if any, who controls such Initial Purchasers within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities or in any information provided by the Company pursuant to Section 4(e), any omission or 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 except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any Initial Purchasers’ Information.

(b) Indemnification of the Company and the Parent. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company and the Parent, each of their respective affiliates, directors and officers and each person, if any, who controls the Company and the Parent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any Initial Purchasers’ Information furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto).

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (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 Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person 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 Person 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 local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for the Initial Purchasers, their respective affiliates, directors and officers

and any control persons of the Initial Purchasers shall be designated in writing by the Initial Purchasers and any such separate firm for the Company and the Parent, their respective directors and officers and any control persons of the Company and the Parent shall be designated in writing by the Company or the Parent. The Indemnifying Person 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 Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than thirty (30) calendar days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person 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 Company and the Parent on the one hand and the Initial Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Parent on the one hand and the Initial Purchasers on the other 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 and the Parent on the one hand and the Initial Purchasers on the other 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 the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Company and the Parent on the one hand and the Initial Purchasers on the other 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 the information supplied by the Company or the Parent or Initial Purchasers’ Information supplied by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company, the Parent and the Initial Purchasers agree that it would not be just and 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 paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall the Initial Purchasers be required to contribute any amount in excess of the amount by which the total discounts and commissions received by the Initial Purchasers with respect to the offering of the Securities exceeds the amount of any damages that the Initial Purchasers have 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to paragraph (d) above are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8. 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 Securities that the defaulting Initial Purchasers agreed but failed to purchase on such Closing Date in the respective proportions which the principal amount of the Securities set forth opposite the name of each remaining non-defaulting Initial Purchaser in Schedule 1 hereto bears to the aggregate principal amount of the Securities set forth opposite the names of all the remaining non-defaulting Initial Purchasers in Schedule 1 hereto; provided, however, that the remaining non-defaulting Initial Purchasers shall not be obligated to purchase any of the Securities on such Closing Date if the aggregate principal amount of the Securities that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on such date exceeds 9.09% of the aggregate principal amount of the Securities to be purchased on such Closing Date and any remaining non-defaulting Initial Purchaser shall not be obligated to purchase more than 110% of the principal amount of the Securities that it agreed to purchase on such Closing Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Initial Purchasers shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Securities to be purchased on such Closing Date. If the remaining

Initial Purchasers do not elect to purchase the principal amount of Securities that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on such Closing Date this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Section 10. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 8, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company for damages caused by its default. If other Initial Purchasers are obligated or agree to purchase the Securities of a defaulting or withdrawing Initial Purchaser, either the remaining Initial Purchasers or the Company may postpone the Closing Date for up to seven (7) 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 Time of Sale Information, the Final Offering Memorandum or in any other document or arrangement.

9. Termination. The obligations of the Initial Purchasers hereunder may be terminated by the Initial Purchasers, in the absolute discretion of the Initial Purchasers, by notice given to the Company prior to the delivery of and payment for the Securities if, prior to that time, any of the events described in Section 6(e), 6(f), 6(l), 6(m) and 6(t) shall have occurred.

10. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and the Parent jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any Issuer Written Communication, any Time of Sale Information and the Final Offering Memorandum (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s and Parent’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Initial Purchasers may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Initial Purchasers not to exceed $15,000); (viii) any fees charged by rating agencies for rating the Securities; (ix) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (x) all expenses and application fees incurred in connection with the approval of the Securities for book-entry transfer by DTC; and (xi) all expenses incurred by the Company in connection with any “road show” presentation to potential investors.

(b) If (i) this Agreement is terminated pursuant to Section 9 (other than due to the events described in Section 6(l) and 6(m)), (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Company and the Parent jointly and severally agree to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the proposed purchase and resale of the Securities contemplated hereby.

11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and any controlling persons referred to herein, and the affiliates, officers and directors of the Initial Purchasers referred to in Section 7 hereof. Nothing 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 provision contained herein. No purchaser of Securities from the Initial Purchasers shall be deemed to be a successor merely by reason of such purchase.

12. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Parent and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company, the Parent or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Parent or the Initial Purchasers.

13. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “Business Day” means any day other than a Saturday, a Sunday or a day on which banking institutions in New York, New York are authorized or required by law or executive order to remain closed; (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (d) the term “written communication” has the meaning set forth in Rule 405 under the Securities Act.

15. Miscellaneous. (a) Authority of the Representatives. Any action by the Initial Purchasers hereunder may be taken by the Representatives on behalf of the Initial Purchasers, and any such action taken by the Representatives shall be binding upon the Initial Purchasers.
