8. (a) (i) Each of the Parent and the Company represents and agrees that, other than the final term sheet in a form substantially consistent with Schedule III hereto and filed pursuant to Section 7(a) hereof, without the prior written consent of the Representatives, it has not made and will not make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the Act; (ii) each Underwriter represents and agrees that, without the prior written consent of the Company, other than one or more term sheets relating to the Securities substantially consistent with Schedule III hereto, containing no “issuer information” (as defined in Rule 433(h)(2) under the Act) that was not included in the Preliminary Prospectus or Pricing Prospectus, it has not made and will not make any offer relating to the Securities that would constitute a free writing prospectus; and (iii) any such free writing prospectus the use of which has been consented to by the Company and the Representatives is listed on Schedule II hereto;

(b) The Company has complied and will comply with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending; and the Company represents that it has satisfied and agrees that it will satisfy the conditions under Rule 433 under the Act to avoid a requirement to file with the Commission any electronic road show; and

9. Each of the Parent and the Company covenants and agrees with the several Underwriters that the Parent and the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Parent’s and the Company’s counsel and accountants in connection with the registration of the Securities under the Act and all other expenses in connection with the

10. The obligations of the Underwriters hereunder shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the Parent and the Company herein are, at and as of the Time of Delivery, true and correct, the condition that the Parent and the Company shall have performed all of their obligations hereunder theretofore to be performed, and the following additional conditions:

18

(b) Sullivan & Cromwell LLP, counsel for the Underwriters, shall have furnished to the Representatives such written opinions, dated the Time of Delivery, in form and substance satisfactory to the Representatives, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters;

(c) Morgan, Lewis & Bockius LLP, counsel for the Company, shall have furnished to the Representatives their written opinion and 10b-5 statement, each dated the Time of Delivery, in the form attached as Annexes IIA and IIB hereto;

(d) Jeffrey M. Taylor, Secretary of the Company and Vice President, Chief SEC Counsel and Secretary of the Parent, shall have furnished to the Representatives his written opinion, dated the Time of Delivery, in the form attached as Annex III hereto;

(g) On or after the Applicable Time, (i) no downgrading shall have occurred in the rating accorded the Parent’s or the Company’s debt securities by S&P Global Ratings, a division of S&P Global Inc., or Moody’s Investors Service, Inc., each a “nationally recognized statistical rating organization”, as that term is defined by Section 3(a)(62) of the Exchange Act, and (ii) neither such organization shall have publicly announced (other than any announcement made prior to the Applicable Time) that it has under surveillance or review, with possible negative implications, its rating of any of the Parent’s or the Company’s debt securities;

(i) Each of the Parent and the Company shall have furnished or caused to be furnished to the Representatives at the Time of Delivery certificates of officers of the Parent and the Company reasonably satisfactory to the Representatives as to the accuracy of the representations and warranties of the Parent and the Company, respectively, herein at and as of the Time of Delivery, as to the performance by the Parent and the Company of all their respective obligations hereunder to be performed at or prior to the Time of Delivery, as to the matters set forth in subsections (a), (f) and (g) of this Section 10 and as to such other matters as the Representatives may reasonably request.

11. (a) The Parent and the Company will, jointly and severally, indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the 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 Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection

20

with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Parent and the Company 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 the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with the Underwriter Information.

(b) Each Underwriter will, severally and not jointly, indemnify and hold harmless the Parent and the Company against any losses, claims, damages or liabilities, joint or several, to which the Parent or the Company may become subject, under the 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 Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only 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 the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with the Underwriter Information; and will reimburse the Parent and the Company for any legal or other expenses reasonably incurred by the Parent or the Company 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 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

21

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. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ one separate counsel, and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate firm (in addition to one local counsel in each jurisdiction) if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) in an action where both the indemnifying and the indemnified party are actual or potential defendants, the indemnified party shall have reasonably concluded that there are actual or potential conflicting interests between the indemnifying party and the indemnified party, including situations in which there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. 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 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. No indemnified party shall, without the written consent of the indemnifying party (such consent not to be unreasonably withheld), 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.

(d) If the indemnification provided for in this Section 11 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 Parent and the Company, on the one hand, and the Underwriters, on the other, from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the

22

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 Parent and the Company, on the one hand, and the Underwriters, 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 Parent and the Company, on the one hand, and the Underwriters, 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 Parent and the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover page of the Prospectus. 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 Parent or the Company on the one hand or the Underwriter Information on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Parent, the Company, and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) 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), no Underwriter shall 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 which such Underwriter 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 Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Parent and the Company under this Section 11 shall be in addition to any liability which the Parent and the Company may otherwise have and shall extend, upon the same terms and conditions, to the directors, officers, employees and agents of each Underwriter and to each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 11 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and employee of the Parent or the Company and to each person, if any, who controls the Parent or the Company within the meaning of the Act.

23

12. (a) If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, the Representatives may in their discretion arrange for any of the Representatives or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Securities on such terms. In the event that, within the respective prescribed periods, the Representatives notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to prepare promptly any amendments to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section 12 with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting

24

Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 9 hereof and the indemnity and contribution agreements in Section 11 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

13. The respective indemnities, agreements, representations, warranties and other statements of the Parent, the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of 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 or on behalf of any Underwriter or any controlling person of any Underwriter, the Parent or the Company, or any officer or director or controlling person of the Parent or the Company, and shall survive delivery of and payment for the Securities.

14. If for any reason, other than a default by the Underwriters in their obligation to purchase the Securities, any Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all reasonable expenses approved in writing by the Representatives, including reasonable fees and disbursements of counsel, incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities not so delivered, but the Parent and the Company shall then be under no further liability to the Underwriters except as provided in Sections 9 and 11 hereof.

15. In all dealings hereunder, the Representatives shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representatives jointly.

16. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to the Representatives in care of: BofA Securities, Inc., 1540 Broadway NY8-540-26-02, New York, NY 10036, Attention: High Grade Transaction Management/Legal, Facsimile: (212) 901-7881, Email: dg.hg_ua_notices@bofa,com; Mizuho Securities USA LLC, 1271 Avenue of the Americas, New York, NY 10020, Attention: Debt Capital Markets Desk; MUFG Securities Americas Inc., 1221 Avenue of the Americas, 6th Floor, New York, NY 10020, Attention: Capital Markets Group, Facsimile: (646) 434-3455; or RBC Capital Markets, LLC, Brookfield Place, 200 Vesey Street 8th Floor, New York, NY 10281, Attention: DCM Transaction Management, Facsimile: (212) 428-6308; and if to the Parent or the Company shall be delivered or sent by mail to the address of the Parent set forth in the Registration Statement or facsimile transmission to ###-###-####, Attention: James.

17. In accordance with the requirements of the USA Patriot Act (Title III of Pub.

18. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Parent and the Company and, to the extent provided in Sections 11 and 13 hereof, the officers and directors of the Parent and the Company and each person who controls the Parent and the Company or any Underwriter, 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.

Counterparts may be delivered via facsimile, electronic mail (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, or other transmission method), and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

Notwithstanding anything herein to the contrary, each of the Parent and the Company are authorized to disclose to any persons the tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Parent and the Company relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax treatment” means U.S. Federal and State income tax treatment, and “tax structure” is limited to any facts that may be relevant to that treatment.

26. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a State of the United States.
