6. In further consideration of the agreements of the Underwriters contained in this Agreement, the Company covenants as follows:

(a) Prior to the termination of the offering of the Securities pursuant to this Agreement, the Company will not file any amendment or supplement to the Registration Statement or the Basic Prospectus (including any Prospectus Supplement relating to the Securities) unless the Company has previously furnished to the Representatives a copy thereof for its review and will not file any such proposed amendment or supplement to which the Representatives reasonably object; provided that the foregoing requirement shall not apply to any of the Company’s periodic filings with the Commission required to be filed pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, which filings the

Company will cause to be timely filed with the Commission and copies of which filings the Company will cause to be delivered to the Representatives upon written request therefor promptly after being filed with the Commission. Subject to the foregoing sentence, the Company will promptly cause each Prospectus Supplement to be filed with the Commission in accordance with Rule 424(b) under the Securities Act. The Company will promptly advise the Representatives (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) under the Securities Act, (ii) of the filing of any amendment or supplement to the Basic Prospectus, (iii) of the filing and effectiveness of any amendment to the Registration Statement, (iv) of any request by the Commission for any amendment of the Registration Statement, or for any amendment of or supplement to the Basic Prospectus or for any additional information, (v) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose and (vi) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or notice of suspension of qualification and, if issued, to obtain as soon as possible the withdrawal of such stop order including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) To prepare a final term sheet, containing solely a description of final terms of the Securities and the offering thereof in the form attached as Schedule III hereto, a copy of which shall be furnished to the Representatives for their review prior to filing. The Company will not file such term sheet without the approval of the Representatives, which approval shall not be unreasonably withheld. Upon receipt of such approval of the Representatives, the Company shall file such term sheet pursuant to Rule 433(d) under the Securities Act within the time required by such Rule.

(c) If, at any time prior to the filing of the Prospectus Supplement pursuant to Rule 424(b) under the Securities Act, any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, the Company will (i) promptly notify the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) subject to the first clause of the first sentence of paragraph (a) of this Section 6, amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to the Representatives in such quantities as the Representatives may reasonably request.

(d) If, at any time when a prospectus relating to the Securities is required to be delivered under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), or until the distribution of any Securities an Underwriter may own as principal has been completed, any event occurs or condition exists as a result of which (i) the Registration Statement or the Prospectus as then amended or supplemented would include an untrue statement of a material fact, or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made at such time, not misleading, or (ii) if, in the opinion of the Representatives or in the opinion of the Company, it is necessary at any time to amend or supplement the Registration Statement or the Prospectus, as then amended or supplemented, to comply with applicable law, the Company will immediately notify each Underwriter by telephone (with confirmation in writing) to suspend solicitation of offers to purchase Securities or any resale thereof and, if so notified by the Company, each Underwriter shall forthwith suspend such solicitation or resale and cease using the Prospectus as then amended or supplemented. The Company shall, at its expense, prepare and cause to be filed promptly with the Commission, subject to the first sentence of paragraph (a) of this Section 6, an amendment or supplement to the Registration Statement or Prospectus as then amended or supplemented that will correct such statement or omission or effect such compliance and will supply such amended or supplemented Prospectus to each Underwriter in such quantities as such Underwriter may reasonably request.

(e) The Company will make generally available to its security holders and to the Representatives as soon as practicable earnings statements that satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder covering the twelve-month period beginning, in each case, not later than the first day of the Company’s fiscal quarter next following the date of the Underwriting Agreement. If such fiscal quarter is the last fiscal quarter of the Company’s fiscal year, such earnings statement shall be made available not later than 90 days after the close of the period covered thereby and in all other cases shall be made available not later than 45 days after the close of the period covered thereby.

(f) The Company will furnish to the Representatives without charge three copies of the Registration Statement and all amendments thereto, including to the extent requested by the Representatives in writing, exhibits, schedules and any documents incorporated by reference therein, and, during the period mentioned in Section 6(d) above, as many copies of the Prospectus (including any preliminary prospectus) and each Issuer Free Writing Prospectus (and any supplements thereto), any documents incorporated by reference therein and any supplements and amendments thereto as the Representatives may reasonably request.

(g) The Company will qualify the Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request and will pay all reasonable expenses (including fees and disbursements of counsel) in connection with such qualification and in connection with the determination of the eligibility of the Securities for investment under the laws of such jurisdictions as the Representatives may designate, provided that the Company shall not be obligated to so qualify the Securities if such qualification subjects it to taxation in respect of doing business in any jurisdiction in which it is not otherwise subject, or requires it to file any general consent to service of process or qualify as a foreign corporation in any jurisdiction in which it is not so qualified.

(h) The Company agrees that, unless it has or shall have obtained the prior written consent (not to be unreasonably withheld) of the Representatives, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433, other than a free writing prospectus containing solely the information contained in the final term sheet prepared and filed pursuant to Section 6(b) hereto; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule IV hereto. Any such free writing prospectus consented to by the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 under the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(i) Prior to the termination of the offering of the Securities, the Company shall furnish to the Representatives such relevant documents and certificates of officers of the Company relating to the business, operations and affairs of the Company, the Registration Statement, the Basic Prospectus, any amendments or supplements thereto, the Indenture, the Securities, this Agreement, and the performance by the Company of its obligations hereunder or thereunder as the Representatives may from time to time reasonably request and shall notify the Representatives promptly in writing when it becomes aware of any downgrading or of its receipt of any notice of (i) any intended or potential downgrading or (ii) any review or possible change that does not indicate the direction of a possible change in the rating accorded any of the Company’s securities by Moody’s or S&P.

(j) The Company will, whether or not any sale of Securities is consummated, pay all expenses incident to the performance of its obligations under the Underwriting Agreement, including: (i) the preparation and filing of the Registration Statement, any preliminary prospectuses, the Prospectus and each Issuer Free Writing Prospectus and all amendments and supplements thereto; (ii) the preparation, issuance and delivery of the Securities; (iii) the fees and disbursements of the Company’s counsel and accountants and of the Trustee and its counsel; (iv) the qualification of the Securities under securities or Blue Sky laws in accordance with the provisions of Section 6(g), including filing fees and the reasonable fees and disbursements of the counsel for the Underwriters in connection therewith and in connection with the preparation of any Blue Sky memoranda (“Blue Sky Memoranda”); (v) the printing and delivery to the Underwriters in quantities as hereinabove stated of copies of the Registration Statement and all amendments thereto, the Basic Prospectus and any amendments or supplements thereto and each Issuer Free Writing Prospectus and any amendments or supplements thereto; (vi) the printing and delivery to the Underwriters of copies of the Indenture and any Blue Sky Memoranda; (vii) any fees charged by rating agencies for the rating of the Securities; (viii) any reasonable out-of-pocket expenses incurred by the Underwriters with the approval of the Company; and (ix) the fees and expenses, if any, incurred with respect to any filing with the Financial Industry Regulatory Authority, Inc.

(k) During the period beginning on the date of this Agreement and continuing to and including the Closing Date, the Company will not, without the prior consent of the Representatives, offer, sell, contract to sell or otherwise dispose of any debt securities of the Company substantially similar to the Securities (other than (i) the Securities that are to be sold pursuant to this Agreement, (ii) other debt securities previously agreed to be sold by the Company and (iii) commercial paper issued in the ordinary course of business).

7. (a) The Representatives shall promptly notify the Company of the completion of the distribution of the Securities.

(b) Each Underwriter, severally and not jointly, agrees with the Company that, unless it has or shall have obtained, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433, other than a free writing prospectus containing solely the information contained in the final term sheet prepared and filed pursuant to Section 6(b) hereto; provided that the prior written consent of the Company shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule IV hereto.

8. (a) The Company agrees to indemnify and hold harmless each Underwriter, the officers, directors, employees and agents of such Underwriter, and each person, if any, who controls such Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages or liabilities, joint or several, caused by or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or in any amendment thereof, or in the Prospectus, any preliminary prospectus, any Permitted Free Writing Prospectus or other free writing prospectus used by the Company or any agent of the Company (other than any Underwriter) or the information contained in the final term sheet as required to be prepared and filed pursuant to Section 6(b) hereof, or in any amendment or supplement to any thereof, 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, not misleading, except insofar as such losses, claims, damages or liabilities are caused by or based upon any such untrue statement or omission or alleged untrue statement or alleged omission based upon information furnished to the Company in writing by or on behalf of such Underwriter expressly for use therein.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and any person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to each such Underwriter, but only with reference to information relating to such Underwriter furnished in writing by such Underwriter expressly for use in the Registration Statement or the Prospectus or any amendments or supplements thereto or in any preliminary prospectus or Permitted Free Writing Prospectus. The Company acknowledges that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and under the heading “Underwriting,” in (i) the third paragraph related to discounts, (ii) the fifth paragraph related to stabilization, overallotment, concessions and syndicate covering transactions and (iii) the second sentence of the sixth paragraph related to market making activities in the preliminary prospectus constitute the only information furnished by or on behalf of the several Underwriters for inclusion in the Registration Statement, the Prospectus, any amendments or supplements thereto or in any preliminary prospectus or Permitted Free Writing Prospectus.

(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 either paragraph (a) or (b) above, 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 reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the actual or potential parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and the indemnified party shall have reasonably concluded that there may be 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 use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest or (iv) 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 proceeding. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings 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 such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representatives, in the case of parties indemnified pursuant to paragraph (a) above and by the Company in the case of parties indemnified pursuant to paragraph (b) above. 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. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel as contemplated by the third sentence of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such

settlement. 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. Failure to notify the indemnifying party as required by the first sentence of this paragraph (c) (1) will not relieve the indemnifying party from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (2) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above.

(d) If the indemnification provided for in paragraph (a) or (b) of this Section 8 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein in connection with any offering of Securities, then the Company and the Underwriters severally agree that 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 Company on the one hand and the Underwriters on the other from the offering of the Securities 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 on the one hand and of the Underwriters on the other in connection with the statements or omissions which 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 Underwriters on the other in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Securities (before deducting expenses) received by the Company and the total discounts and commissions received by the Underwriters in respect thereof, in each case as set forth in the Prospectus, bear to the total aggregate public offering price of such Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. The relative fault of the Company on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 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 considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party 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 reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. 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 remedies provided for in this Section 8 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.

The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company in this Agreement shall remain operative and in full force and effect regardless of (i) termination of this Agreement, (ii) any investigation made by any Underwriter or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its directors or officers or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

9. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in the Underwriting Agreement bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in the Underwriting Agreement, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities. If arrangements satisfactory to the non-defaulting Underwriters and the Company for the purchase of at least 90% of the aggregate principal amount of the Securities are not made within 36 hours after such default or if such non- defaulting Underwriters do not agree to purchase at least 90% of the aggregate principal amount of such Securities, this Agreement will terminate without liability to any non-defaulting Underwriter or the Company; provided, however, that if such non-defaulting Underwriters agree to purchase at least 90% but less than 100% of the aggregate principal amount of such Securities, the Company, at its option, may terminate this Agreement and no non-defaulting Underwriter or the Company shall have any liability in connection therewith. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five business days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any non-defaulting Underwriter for damages occasioned by its default hereunder.

10. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

11. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company, if prior to the Closing Date (i) trading in securities generally on the New York Stock Exchange, the Nasdaq Global Market or the Chicago Stock Exchange shall have been suspended or materially limited, (ii) a general moratorium on commercial banking activities in New York shall have been declared by either federal or New York State authorities, (iii) there shall have occurred a material disruption in securities settlement, payment or clearance services in the United States or (iv) there shall have occurred any material outbreak or escalation of hostilities or other calamity or crisis and, in the case of any of the events described in clauses (i) through (iv) above, the effect of such event on the financial markets of the United States, in the reasonable judgment of the Representatives, is so material and adverse that it is impractical to market the Securities on the terms and in the manner contemplated by the Disclosure Package and the Prospectus (exclusive of any amendment of supplement thereto).

12. If this Agreement shall be terminated by the Underwriters or any of them, 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 except pursuant to Section 9 hereof, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally through the Representatives on demand, for all out-of-pocket expenses (including the reasonable fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement.

13. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

14. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to a contract executed and performed in such State without giving effect to the conflicts of laws principles thereof.

15. The Company hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Company and (c) the Company’s engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

16. (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.

(i) a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. §1841(k);

(ii) a “Covered Entity” means any of the following: (A) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. §252.82(b); (B) “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. §47.3(b); or (C) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. §382.2(b);

(iii) “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§252.81, 47.2 or 382.1, as applicable; and

(iv) “U.S. Special Resolution Regime” means each of (A) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (B) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to us the enclosed duplicate hereof, whereupon this letter and your acceptance shall represent a binding agreement between the Company and the several Underwriters.
