Information Technology. The Guarantor’s and its subsidiaries’ (including the Issuer’s) information technology assets and equipment, computers, systems, networks, hardware, software, websites, applications, and databases (collectively, “IT Systems”) are adequate for, and operate and perform in all material respects as required in connection with the operation of the business of the Guarantor and its subsidiaries as currently conducted, free and clear of all material bugs, errors, defects, Trojan horses, time bombs, malware and other corruptants, except as would

Any certificate signed by an officer of the Issuer and delivered to the Representatives or to counsel for the Underwriters shall be deemed to be a representation and warranty by the Issuer to each Underwriter as to the matters set forth therein. SECTION 2. Purchase, Sale and Delivery of the Securities. (a) Purchase and Sale of the Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Issuer agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Issuer the respective principal amount of Securities set forth in Schedule A opposite the name of such Underwriter, at a purchase price equal to 99.067% of the principal amount thereof, plus accrued interest, if any, from May 26, 2021, to the date of payment and delivery. (b) The Closing Date. Delivery of certificates for the Securities to be purchased by the Underwriters and payment therefor shall be made at the offices of Willkie Farr & Gallagher LLP, 787 Seventh Avenue, New York, New York 10019 (or at such other place, including remotely by electronic transmission), at 10:00 a.m. New York City time on May 26, 2021 or such other later date not more than three business days after such date as the Representatives shall designate by notice to the Issuer (the time and date of such closing are called the “Closing Date”). (c) Public Offering of the Securities. The Representatives hereby advise the Issuer and the Guarantor that the Underwriters intend to offer for sale to the public, as described in the Prospectus, their respective portions of the Securities as soon after this Agreement has been executed as the Representatives, in their sole judgment, have determined is advisable and practicable. (d) Payment for the Securities. Payment for the Securities shall be made on the Closing Date by wire transfer of immediately available funds to a bank account designated by the Issuer against delivery to the Representatives for the respective accounts of the Underwriters of certificates for the Securities to be purchased by them. It is understood that each Underwriter has

13 741716996.2 authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Securities which it has agreed to purchase. The Representatives, in their individual capacity and not as representatives of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Securities to be purchased by any Underwriter whose funds have not been received by the Closing Date, but such payment shall not relieve such Underwriter from its obligations hereunder. (e) Delivery of the Securities. Delivery of the Securities shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct. Certificates for the Securities shall be in global form and registered in such names and in such denominations as the Representatives may request upon at least forty eight hours’ prior notice to the Issuer. Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Underwriters. (f) Delivery of Prospectuses to the Underwriters. Not later than 10:00 a.m. on the second business day following the date the Securities are first released by the Underwriters for sale to the public, the Issuer and the Guarantor shall deliver or cause to be delivered copies of the Prospectus in such quantities and at such places as the Representatives shall request. SECTION 3. Covenants. Each of the Issuer and the Guarantor, jointly and severally, hereby covenants and agrees with each Underwriter as follows: (a) Review of Proposed Amendments and Supplements. During the period beginning at the Applicable Time and ending on the later of the Closing Date or such date, as in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales by an Underwriter or a dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act (the “Prospectus Delivery Period”), prior to amending or supplementing the Registration Statement, the Disclosure Package or the Prospectus (including any amendment or supplement through incorporation by reference of any report filed under the Exchange Act), the Issuer and the Guarantor shall furnish to the Representatives for review a copy of each such proposed amendment or supplement, and neither the Issuer nor the Guarantor shall file or use any such proposed amendment or supplement to which the Representatives reasonably object. The Representatives shall provide notice to the Issuer if the Prospectus Delivery Period has not ended on the date of the Closing Date, and upon such later date as the Prospectus Delivery Period has ended. (b) Securities Act Compliance. During the Prospectus Delivery Period, the Issuer and the Guarantor shall promptly advise the Representatives in writing (i) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission, (ii) of the time and date of any filing of any post-effective amendment to the Registration Statement or any amendment or supplement to any preliminary prospectus or the Prospectus, (iii) of the time and date that any post-effective amendment to the Registration Statement becomes effective and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order or notice preventing or suspending the use of the Registration Statement, any preliminary prospectus or the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act. The Issuer and the Guarantor each shall use its best efforts to prevent the issuance of any such stop

14 741716996.2 order or prevention or suspension of such use during the Prospectus Delivery Period. If during the Prospectus Delivery Period the Commission shall enter any such stop order or order or notice of prevention or suspension at any time, the Issuer and the Guarantor each will use its best efforts to obtain the lifting of such order at the earliest possible moment, or will file a new registration statement and use its best efforts to have such new registration statement declared effective as soon as practicable. Additionally, the Issuer and the Guarantor each agree that it shall comply with the provisions of Rules 424(b) and 430B, as applicable, under the Securities Act, including with respect to the timely filing of documents thereunder, and will use its reasonable efforts to confirm that any filings made by the Issuer or the Guarantor under such Rule 424(b) were received in a timely manner by the Commission. (c) Exchange Act Compliance. The Issuer and the Guarantor, during the Prospectus Delivery Period, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act. (d) Amendments and Supplements to the Registration Statement, Prospectus and Other Securities Act Matters. If, during the Prospectus Delivery Period, any event or development shall occur or condition exist as a result of which the Disclosure Package or the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading, or if it shall be necessary to amend or supplement the Disclosure Package or the Prospectus, or to file under the Exchange Act any document incorporated by reference in the Disclosure Package or the Prospectus, in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading, or if, in the opinion of the Representatives, it is otherwise necessary to amend or supplement the Registration Statement, the Disclosure Package or the Prospectus, or to file under the Exchange Act any document incorporated by reference in the Disclosure Package or the Prospectus, or to file a new registration statement containing the Prospectus, in order to comply with law, including in connection with the delivery of the Prospectus, the Issuer and the Guarantor agree to (i) notify the Representatives of any such event or condition and (ii) promptly prepare (subject to Section 3(a) hereof), file with the Commission (and use their best efforts to have any amendment to the Registration Statement or any new registration statement to be declared effective) and furnish at their own expense to the Underwriters and to dealers, amendments or supplements to the Registration Statement, the Disclosure Package or the Prospectus, or any new registration statement, necessary in order to make the statements in the Disclosure Package or the Prospectus as so amended or supplemented, in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading or so that the Registration Statement, the Disclosure Package or the Prospectus, as amended or supplemented, will comply with law. (e) Final Term Sheet. The Issuer and the Guarantor will prepare a final term sheet containing solely a description of the Securities, including the price at which the Securities are to be sold to the public, in a form approved by the Representatives and attached hereto as Schedule C, and will file such term sheet pursuant to Rule 433(d) under the Securities Act within the time required by such rule (such term sheet, the “Final Term Sheet”).

15 741716996.2 (f) Permitted Free Writing Prospectuses. Each of the Issuer and the Guarantor represents that it has not made, and agrees that, unless it obtains the prior written consent of the Representatives, it will not make, and each Underwriter, severally and not jointly, represents that it has not made, and agrees that, unless it obtains the prior written consent of the Issuer and the Guarantor, it will not make, in each case, any offer relating to the Securities that constitutes or would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) required to be filed by the Issuer or the Guarantor with the Commission or retained by the Issuer or the Guarantor under Rule 433 under the Securities Act; provided that the prior written consent of the Representatives hereto shall be deemed to have been given in respect of the Issuer Free Writing Prospectuses included in Schedule B hereto. Any such free writing prospectus consented to by the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Issuer and the Guarantor each agree that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) 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. The Issuer and the Guarantor consent to the use by the Underwriters of a free writing prospectus that (a) is not an Issuer Free Writing Prospectus, and (b) contains only (i) information describing the preliminary terms of the Securities or their offering, (ii) information permitted by Rule 134 under the Securities Act or (iii) information that describes the final terms of the Securities or their offering and that is included in the Final Term Sheet of the Issuer and the Guarantor contemplated in Section 3(e). (g) Copies of the Disclosure Package and the Prospectus. The Issuer and the Guarantor agree to furnish the Underwriters, without charge, during the Prospectus Delivery Period, as many copies of the Disclosure Package and the Prospectus and any amendments and supplements thereto (including any documents incorporated or deemed incorporated by reference therein) as the Underwriters may request. (h) Copies of the Registration Statement. The Issuer and the Guarantor will furnish to the Representatives and counsel for the Underwriters signed copies of the Registration Statement (including exhibits thereto). (i) Blue Sky Compliance. The Issuer and the Guarantor shall cooperate with the Representatives and counsel for the Underwriters to qualify or register the Securities for sale under (or obtain exemptions from the application of) the state securities or blue sky laws or Canadian provincial securities laws or other foreign laws of those jurisdictions designated by the Representatives, and shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Securities. Neither the Issuer nor the Guarantor shall be required to qualify as a foreign corporation or to take any action that would subject either the Issuer or the Guarantor to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign corporation, other than those arising out of the offering or sale of the Securities in any jurisdiction where it is not now so subject. The Issuer and the Guarantor will advise the Representatives promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order

16 741716996.2 suspending such qualification, registration or exemption, the Issuer and the Guarantor each shall use their best efforts to obtain the withdrawal thereof at the earliest possible moment. (j) Registration Statement Fees. The Issuer and the Guarantor will pay the fees applicable to the Registration Statement in connection with the offering of the Securities within the time required by Rule 456(b)(1)(i) under the Securities Act (without reliance on the proviso to Rule 456(b)(1)(i) under the Securities Act) and in compliance with Rule 456(b) and Rule 457(r) under the Securities Act. (k) Earnings Statement. The Guarantor and, to the extent separately required pursuant to Rule 158 under the Securities Act, the Issuer will timely file such reports pursuant to the Exchange Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the Securities Act. (l) Agreement Not to Offer or Sell Additional Securities. During the period commencing on the date hereof and ending on the Closing Date, the Issuer and the Guarantor will not, without the prior written consent of the Representatives (which consent may be withheld at the sole discretion of the Representatives), directly or indirectly, sell, offer, contract or grant any option to sell, pledge, transfer or establish an open “put equivalent position” or liquidate or decrease a “call equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition of), or announce the offering of, or file any registration statement under the Securities Act in respect of, any debt securities or warrants to purchase or otherwise acquire debt securities, in each case issued or guaranteed by the Guarantor or any of its subsidiaries, including the Issuer, substantially similar to the Securities, other than commercial paper issued in the ordinary course of business, and other than as contemplated by this Agreement with respect to the Securities. (m) No Manipulation of Price. Neither the Guarantor nor the Issuer will take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, under the Exchange Act or otherwise, the stabilization or manipulation of the price of any securities of the Guarantor or the Issuer to facilitate the sale or resale of the Securities. The Representatives, on behalf of the several Underwriters, may, in their sole discretion, waive in writing the performance by the Issuer or the Guarantor of any one or more of the foregoing covenants or extend the time for their performance. SECTION 4. Payment of Expenses. The Issuer and the Guarantor, jointly and severally, covenant and agree with the Underwriters that the Issuer and the Guarantor will pay, or cause to be paid, in such proportions as the Issuer and the Guarantor may agree among themselves, all costs, fees and expenses incurred in connection with the performance of their obligations hereunder and in connection with the transactions contemplated hereby, including without limitation: (i) the fees and expenses associated with listing the Securities on the New York Stock Exchange; (ii) all necessary issue, transfer and other stamp taxes in connection with the issuance and sale of the Securities to the Underwriters; (iii) the fees, disbursements and expenses of the Issuer’s and the

17 741716996.2 Guarantor’s counsel and accountants in connection with the registration of the Securities under the Securities Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, any preliminary prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (iv) the cost of printing or producing any Agreement among Underwriters, this Agreement, the Blue Sky Memorandum, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (v) all expenses in connection with the qualification of the Securities for offering and sale under state securities laws as provided in Section 3(i) hereof, including the properly documented fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky Memorandum (such fees and disbursements not to exceed $14,000); (vi) the filing fees incident to, and the properly documented fees and disbursements of counsel for the Underwriters in connection with, securing any required review by FINRA of the terms of the sale of the Securities; (vii) any fees charged by rating agencies for rating the Securities; (viii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (ix) the costs and expenses of the Issuer and the Guarantor relating to presentations or meetings undertaken in connection with the marketing of the offering and sale of the Securities to prospective investors and the Underwriters’ sales forces, including, without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations, travel, lodging and other expenses incurred by the officers of the Issuer and the Guarantor and any such consultants, and the cost of any aircraft chartered in connection with the road show; and (x) all other costs and expenses incident to the performance of the Issuer’s and the Guarantor’s obligations hereunder which are not otherwise specifically provided for in this section.

SECTION 5. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Securities as provided herein on the Closing Date shall be subject to the accuracy of the representations and warranties on the part of the Issuer and the Guarantor contained herein and set forth in Section 1 hereof as of the date hereof and as of the Closing Date, to the accuracy of the statements of the Issuer and the Guarantor made in any certificates pursuant to the provisions hereof, to the timely performance by the Issuer and the Guarantor of their respective covenants and obligations hereunder, and to each of the following additional conditions: (a) Accountants’ Comfort Letter.

Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure to so notify the indemnifying party (i) will not relieve it 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 (ii) will not, in any event, relieve the indemnifying party from any liability other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified

22 741716996.2 party; provided, however, such indemnified party shall have the right to employ its own counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party, unless: (i) the employment of such counsel has been specifically authorized by the indemnifying party; (ii) the indemnifying party has failed promptly to assume the defense and employ counsel reasonably satisfactory to the indemnified party; or (iii) the named parties to any such action (including any impleaded parties) include both such indemnified party and the indemnifying party or any affiliate of the indemnifying party, and such indemnified party shall have reasonably concluded that either (x) there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party or such affiliate of the indemnifying party or (y) a conflict may exist between such indemnified party and the indemnifying party or such affiliate of the indemnifying party (it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to a single firm of local counsel) for all such indemnified parties, which firm shall be designated in writing by the Representatives and that all such reasonable fees and expenses shall be reimbursed as they are incurred). (d) Settlements. The indemnifying party under this Section 7 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 against any loss, claim, damage, liability or expense 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 fees and expenses of counsel as contemplated by Section 7(c) hereof, 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, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (y) 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. SECTION 8. Contribution. If the indemnification provided for in Section 7 is for any reason unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuer and the Guarantor, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement 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

23 741716996.2 to in clause (i) above but also the relative fault of the Issuer and the Guarantor, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Issuer and the Guarantor, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses but after deducting the underwriting discount) received by the Issuer, and the underwriting discount received by the Underwriters, in each case as set forth on the front cover of the Prospectus bear to the aggregate initial public offering price of the Securities as set forth on such cover. The relative fault of the Issuer and the Guarantor, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Issuer or the Guarantor, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 7(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 7(c) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 8; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 7(c) for purposes of indemnification. The Issuer, the Guarantor 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 equitable considerations referred to in this Section 8. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public. 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 Underwriters’ obligations to contribute pursuant to this Section 8 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A. For purposes of this Section 8, each director, officer, employee and agent of an Underwriter and each person, if any, who controls or is under common control with an Underwriter within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Issuer and the Guarantor, each officer of the Issuer and the Guarantor who signed the Registration Statement and each person, if any, who controls the Issuer and the Guarantor within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Issuer and the Guarantor.

24 741716996.2 SECTION 9. Default of One or More of the Several Underwriters. If, on the Closing Date, as the case may be, any one or more of the several Underwriters shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Securities to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportions that the aggregate principal amount of the Securities set forth opposite their respective names on Schedule A bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs exceeds 10% of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to the Representatives and the Issuer for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Section 4, Section 6, Section 7 and Section 8 shall at all times be effective and shall survive such termination. In any such case either the Representatives or the Issuer shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected. As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 9. Any action taken under this Section 9 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. SECTION 10. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representatives by notice given to the Issuer and the Guarantor if at any time (i) trading or quotation in any of the Issuer’s or the Guarantor’s securities shall have been suspended or limited by the Commission or by the New York Stock Exchange, or trading in securities generally on the New York Stock Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established on the New York Stock Exchange; (ii) a general banking moratorium shall have been declared by federal or New York authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States has occurred; or (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to market the Securities in the manner and on the terms described in the Prospectus or to enforce contracts for the sale of securities. Any termination pursuant to this Section 10 shall be without liability on the part of (a) the Issuer or the Guarantor to any Underwriter, except to the extent the Issuer and the Guarantor shall be obligated to reimburse the expenses of the Underwriter pursuant to Sections 4 and 6 hereof or (b) any Underwriter to the Issuer or the Guarantor.

25 741716996.2 SECTION 11. No Advisory or Fiduciary Responsibility. The Issuer and the Guarantor acknowledge and agree that (i) the purchase and issuance of the Securities by the Underwriters pursuant to this Agreement is an arm’s-length commercial transaction between the Issuer and the Guarantor, on the one hand, and the several Underwriters, on the other hand, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Issuer or the Guarantor, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Issuer or the Guarantor with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Issuer on other matters) or any other obligation to the Issuer or the Guarantor except the obligations expressly set forth in this Agreement, (iv) the Issuer and the Guarantor have consulted their own legal and financial advisors to the extent they deemed appropriate and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Issuer and the Guarantor have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate. The Issuer and the Guarantor agree that they will not claim that any Underwriter has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Issuer or the Guarantor, in connection with such transaction or the process leading thereto. This Agreement supersedes all prior agreements and understandings (whether written or oral) among the Issuer, the Guarantor and the several Underwriters, or any of them, with respect to the subject matter hereof. SECTION 12. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Issuer, the Guarantor, their officers, and of the several Underwriters set forth in or made pursuant to this Agreement (i) will remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the officers or employees of any Underwriter or any person controlling or under common control with any Underwriter, or the Issuer, the Guarantor, the officers or employees of the Issuer or the Guarantor, or any person controlling the Issuer or the Guarantor, as the case may be or (B) acceptance of the Securities and payment for them hereunder and (ii) will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

The term “successors and assigns” shall not include a purchaser of any of the Securities from any of the several Underwriters merely because of such purchase. SECTION 15. Partial Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof. If any Section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable. SECTION 16. Governing Law Provisions. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE. (a) Consent to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan, or the courts of the State of New York in each case located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. The Guarantor has irrevocably appointed the Issuer, 1633 Broadway, New York, New York 10019, as its agent to receive service of process or other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in the City and County of New York. (b) Waiver of Immunity. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended. SECTION 17. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original,

28 741716996.2 with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement. Each of the parties hereto acknowledges that it is a sophisticated business person who was adequately represented by counsel during negotiations regarding the provisions hereof, including, without limitation, the indemnification provisions of Section 7 and the contribution provisions of Section 8, and is fully informed regarding said provisions. Each of the parties hereto further acknowledges that the provisions of Sections 7 and 8 hereto fairly allocate the risks in light of the ability of the parties to investigate the Issuer, the Guarantor and their respective affairs and business in order to assure that adequate disclosure has been made in the Registration Statement, any preliminary prospectus and the Prospectus (and any amendments and supplements thereto), as required by the Securities Act and the Exchange Act. SECTION 18. Recognition of the U.S. Special Resolution Regimes. (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. (c) As used in this section: “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). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b).
