Each Depositary Receipt will evidence one or more Depositary Shares. This Underwriting Agreement is referred to herein as this “Agreement”.

The Company has previously issued 5,520,000 Depositary Shares (the “Existing Depositary Shares”). The Depositary Shares offered hereby will have identical terms to the Existing Depositary Shares and will be treated as a single class of securities with the Existing Depositary Shares.

1. The Company represents and warrants to each of the several Underwriters, as of the date hereof, as of the Closing Time (each such date, a “Representation Date”), and as of the Applicable Time, and agrees with each of the several Underwriters, as follows:

(a) The Company has prepared and filed with the United States Securities and Exchange Commission (the “Commission”) an automatically effective shelf registration statement onForm S-3 (RegistrationNo. 333-238707), including each prospectus included therein, which registration statement became automatically effective under the Securities Act of 1933, as amended (the “1933 Act”), at the time it was filed with the Commission in accordance with Rule 462(e) of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”), and the Company has filed such post-effective amendments thereto as may be required prior to the

execution of this Agreement and each such post-effective amendment is effective under the 1933 Act. Such registration statement covers the registration of the Preferred Stock and the Depositary Shares under the 1933 Act. Promptly after execution and delivery of this Agreement, the Company will file a final prospectus supplement in accordance with the provisions of Rule 430B (“Rule 430B”) of 1933 Act Regulations and paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations. Any information included in such final prospectus supplement that was omitted from such registration statement at the time it originally became effective but that is deemed to be part of and included in such registration statement pursuant to Rule 430B is referred to as “Rule 430B Information.” Such registration statement, at any given time, including the amendments thereto at such time, the exhibits and any schedules thereto at such time, the documents incorporated and deemed to be incorporated by reference therein pursuant to Item 12 of FormS-3 under the 1933 Act at such time, and the documents and information (including, without limitation, any Rule 430B Information) otherwise deemed to be a part thereof or included therein by 1933 Act Regulations at such time, is herein called the “Registration Statement.” The Company’s base prospectus dated May 27, 2020 that was included in the Registration Statement at the time of its effectiveness (the “Base Prospectus”) and the prospectus supplement dated June 8, 2020, relating to the offering of the Securities, in the form first furnished to the Underwriters by the Company for use in connection with the offering of the Securities (whether to meet the requests of purchasers pursuant to Rule 173 under the 1933 Act Regulations or otherwise), including the documents incorporated and deemed to be incorporated by reference therein pursuant to Item 12 of FormS-3 under the 1933 Act at such time, are hereinafter called, collectively, the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, the Prospectus, any Issuer-Represented Free Writing Prospectus (as hereinafter defined) or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval (“EDGAR”) system. The Company meets the requirements for use of FormS-3 under the 1933 Act. The Company qualifies as a “well-known seasoned issuer” under Rule 405 of the 1933 Act Regulations and meets the requirements under the 1933 Act specified in the Financial Industry Regulatory Authority (“FINRA”) Conduct Rule 5110(b)(7)(C)(i).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” (or other references of like import) in the Registration Statement or the Prospectus shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated or deemed to be incorporated by reference in, or otherwise deemed by the 1933 Act Regulations (including, without limitation, pursuant to Rule 430B(f) of the 1933 Act Regulations) to be a part of or included in, the Registration Statement or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “1934 Act”), which is incorporated or deemed to be incorporated by reference in the Registration Statement or the Prospectus, as the case may be.

(b) At the time of the original filing of the Registration Statement, at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the 1933 Act Regulations) of the Securities, at the time when sales of the Securities were first made, and at each Representation Date, the Company was not, is not and will not be an “ineligible issuer” as defined in Rule 405 under the 1933 Act.

(c) The Registration Statement is an “automatic shelf registration statement” as defined under Rule 405 of the Securities Act that has been filed with the Commission not earlier than three years prior to the date hereof; and no notice of objection of the Commission to the use of such registration statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act has been received by the Company. No stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any written request on the part of the Commission for additional information with respect to the Registration Statement (or any document incorporated or deemed to be incorporated therein by reference pursuant to the 1934 Act) has been complied with in all material respects.

(d) At the respective times that the Registration Statement and any amendments thereto became effective, the Registration Statement and any amendments thereto complied in all material respects with the requirements of the 1933 Act, the 1933 Act Regulations, and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

At the time the Prospectus or any amendment or supplement thereto was issued and at each Representation Date, neither the Prospectus nor any amendment or supplement thereto included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(f) On or after the date hereof (i) no downgrading shall have occurred in the published rating accorded to the Securities or any other of the Company’s securities by any “nationally recognized statistical rating organization,” as that term is defined by the Commission under Section 3(a)(62) of the 1934 Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its published rating of the Securities or any other of the Company’s securities.

(a) (i) The Company shall indemnify and hold harmless each Underwriter, its directors, officers, employees and affiliates and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject, under the 1933 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 General Disclosure Package, the Prospectus or any individualIssuer-Represented Limited-Use Free Writing Prospectus, when considered together with the General Disclosure Package, or any amendment or supplement thereto, 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, in light of the circumstances in which they were made, not misleading and will reimburse each such indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such suit, action, proceeding or claim as such expenses are incurred; provided, however, that 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 General Disclosure Package, the Prospectus or any individualIssuer-Represented Limited-Use Free Writing Prospectus, when considered together with the General Disclosure Package, or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein (provided that the Company and the Underwriters hereby acknowledge and agree that the only information that the Underwriters have furnished to the Company specifically for inclusion in the Registration Statement, the General Disclosure Package, the Prospectus or any individualIssuer-Represented Limited-Use Free Writing Prospectus, or any amendment or supplement thereto, are the concession and reallowance figures, if any, appearing in the Prospectus in the section entitled “Underwriting” (the “Underwriters’ Information”).

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act against any losses, claims, damages or liabilities to which the Company, or any such director, officer or controlling person may become subject, under the 1933 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 General Disclosure Package, the Prospectus, or any individualIssuer-Represented Limited-Use Free Writing Prospectus, when considered together with the General Disclosure Package, or any amendment or supplement thereto, 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 such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the General Disclosure Package, the Prospectus or such individualIssuer-Represented Limited-Use Free Writing Prospectus, when considered together with the General Disclosure Package, or any such amendment or supplement, in reliance upon and in conformity with the Underwriters’ Information; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such suit, action, proceeding 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 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. 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.

(d) If the indemnification provided for in this Section 8 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 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 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 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 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 Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table 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 Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 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 of the underwriting discounts and commissions received by the Underwriter pursuant to this Agreement exceeds the amount of any damages that 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 1933 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 Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who

controls (within the meaning of the 1933 Act) any Underwriter, or any of the respective affiliates, partners, directors, officers and employees of any Underwriter or any such controlling person; and the several obligations of the Underwriters under this Section 8 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 director of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company), each officer of the Company who signs the Registration Statement and to each person, if any, who controls the Company, as the case may be, within the meaning of the 1933 Act.

9. If one or more of the Underwriters shall fail at the Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more ofthe non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements withinsuch 24-hour period, then:

(a) if the number of Defaulted Securities does not exceed 10% of the aggregate principal amount of Securities to be purchased on such date, each ofthe non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations ofall non-defaulting Underwriters, or

(b) if the number of Defaulted Securities exceeds 10% the aggregate principal amount of Securities to be purchased on such date, this Agreement shall terminate without liability on the part ofany non-defaulting Underwriter.

No action taken pursuant to this Section 9 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement either (i) the Representatives or (ii) the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement, General Disclosure Package or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 9.

10. The respective indemnities, agreements, representations, warranties and other statements of 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, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities.

11.

(a) The Representatives may terminate this Agreement, by notice to the Company, at any time prior to the Closing Time, if on or after the date hereof there has been any of the following events, circumstances or occurrences: (i) a suspension or material limitation in trading in securities generally on the NASDAQ, the NASDAQ Global Market or the NASDAQ Global Select Market or any setting of minimum or maximum prices for trading on such exchange; (ii) a suspension or material limitation in trading of any securities of the Company on any exchange or inthe over-the-counter market; (iii) a general moratorium on commercial banking activities declared by either federal, New York or Tennessee state authorities; (iv) any major disruption of settlements of securities, payment, or clearance services in the United States or any other country where such securities are listed, or (v) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war or a material adverse change in the financial markets, or any other calamity or crisis, if the effect of any such event specified in this clause (v) in the reasonable judgment of the Representatives makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities being delivered at the Time of Delivery on the terms and in the manner contemplated in either the General Disclosure Package or the Prospectus or to enforce contracts for the sale of the Securities.

(b) If this Agreement is terminated pursuant to Section 9 hereof, then the Company shall not thereafter be under any liability to any Underwriter, except as provided in Sections 6 and 8 hereof; but, if for any other reason, any Securities are not delivered by or on behalf of the Company as provided herein, including because any of the conditions in Section 7 hereof are not satisfied or because of any termination pursuant to Section 11(a) hereof, then the Company will reimburse the Underwriters through the Representatives for allreasonable out-of-pocket expenses, including reasonable fees and disbursements of counsel, incurred by the Underwriters in connection with the transactions contemplated hereby, including, without limitation, marketing, syndication and travel expenses incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities not so delivered, but the Company shall then be under no further liability to the Underwriters except as provided in Sections 6 and 8 hereof.

12. 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.

For purposes of this Agreement, (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); (B) “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); (C) “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 (D) “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.
