(ff) The Company (i) has not alone engaged in any Testing-the-Waters Communication with any person other than Testing-the-Waters Communications with the consent of the Representatives with entities that are reasonably believed to be qualified institutional buyers within the meaning of Rule 144A under the Securities Act or institutions that are reasonably believed to be accredited investors within the meaning of Rule 501 under the Securities Act and (ii) has not authorized anyone other than the Representatives to engage in Testing-the-Waters Communications. The Company reconfirms that the Representatives has been authorized to act on its behalf in undertaking Testing-the-Waters Communications. The Company has not distributed any Testing-the-Waters Communication that is a written communication within the meaning of Rule 405 under the Securities Act other than those listed on Schedule IV hereto. “Testing-the-Waters Communication” means any communication with potential investors undertaken in reliance on Section 5(d) or Rule 163B of the Securities Act. (gg) The Company and its Subsidiaries employ disclosure controls and procedures (as such term is defined in Rule 13a-15 of the Exchange Act Regulations), which (A) are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms and that material information relating to the Company and its Subsidiaries is made known to the Company’s principal executive officer and principal financial officer by others within the Company and its Subsidiaries to allow timely decisions regarding disclosure, (B) have been evaluated by management of the Company for effectiveness as of the end of the Company’s most recent fiscal quarter, and (C) were then effective in all material respects to perform the functions for which they were established. Based on the evaluation of the Company’s and each Subsidiary’s disclosure controls and procedures described above, the Company is not aware of (1) any significant deficiency in the design or operation of internal controls which could adversely affect the Company’s or its Subsidiaries’ ability to record, process, summarize and report financial data or any material weakness in internal controls or (2) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s or its Subsidiaries’ internal controls. Since the most recent evaluation of the Company’s disclosure controls and procedures described above,

13 there have been no changes in internal controls or in other factors that could significantly affect internal controls. Within the next 90 days the Company does not reasonably expect to publicly disclose or report to the Audit Committee or the Board of Directors a material weakness, change in internal control over financial reporting or fraud involving management or other employees who have a significant role in internal control over financial reporting, any violation of, or failure to comply with, the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act or the Exchange Act, or any matter related to internal control over financial reporting which, if determined adversely, would result in a Material Adverse Effect. (hh) There is and has been no failure on the part of the Company or any of the Company’s directors or officers, in their capacities as such, to comply with any provision of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act and the rules and regulations promulgated in connection therewith, including Section 402 related to loans and Sections 302 and 906 related to certifications. (ii) Each financial or operational projection or other “forward-looking statement” (as defined by Section 27A of the Securities Act or Section 21E of the Exchange Act) contained in the Registration Statement, the Time of Sale Prospectus and the Prospectus (A) was so included by the Company in good faith and with reasonable basis after due consideration by the Company of the underlying assumptions, estimates and other applicable facts and circumstances, and (B) is accompanied by meaningful cautionary statements identifying those factors that could cause actual results to differ materially from those in such forward-looking statement. No such statement was made with the knowledge of an executive officer or director of the Company that it was false or misleading. (jj) The statements under the captions “Supervision and Regulation” and “Legal Proceedings” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, insofar as they purport to describe legal matters or provisions of the laws and regulations or documents referred to therein, as supplemented and updated by the Company’s subsequently filed Quarterly Reports on Form 10-Q, are accurate, complete and fair in all material respects; and the statements set forth in the Time of Sale Prospectus and the Prospectus under the caption “Material U.S. Federal Income Tax Considerations” constitute a fair summary of the principal U.S. federal income tax consequences of an investment in the Securities. (kk) The Company is not in violation of its articles of incorporation or bylaws; none of the Subsidiaries is in violation of its charter, bylaws or other organizational documents and neither the Company nor any of its Subsidiaries is in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company or any of its Subsidiaries is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any Subsidiary is subject, or in violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory authority, except for such violations or defaults that would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

14 (ll) The Company is in compliance in all material respects with the requirements of the New York Stock Exchange (“NYSE”) for continued listing of the Common Stock thereon. The Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or the listing of the Common Stock on the NYSE, nor has the Company received any notification that the Commission or the NYSE is contemplating terminating such registration or listing. The transactions contemplated by this Agreement will not contravene the rules or regulations of the NYSE. (mm) No labor dispute with the employees of the Company or any Subsidiary exists or, to the knowledge of the Company, is imminent. The Company is not aware of any existing or imminent labor disturbance by the employees of any of its or any Subsidiary’s principal suppliers, vendors, customers or contractors, which, in either case, would, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any of the Significant Subsidiaries is engaged in any unfair labor practice; except for matters which would not, individually or in the aggregate, have a Material Adverse Effect, (A) there is (1) no unfair labor practice complaint pending or, to the Company’s knowledge, threatened against the Company or any of the Significant Subsidiaries before the National Labor Relations Board or any similar domestic or foreign body, and no grievance or arbitration proceeding arising out of or under collective bargaining agreements is pending or, to the Company’s knowledge, threatened, (2) no strike, labor dispute, slowdown or stoppage pending or, to the Company’s knowledge, threatened against the Company or any of the Significant Subsidiaries and (3) no union representation dispute currently existing concerning the employees of the Company or any of the Significant Subsidiaries, (B) to the Company’s knowledge, no union organizing activities are currently taking place concerning the employees of the Company or any of the Significant Subsidiaries and (C) there has been no violation of any federal, state, local or foreign law relating to discrimination in the hiring, promotion or pay of employees, any applicable wage or hour laws or any provision of the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”) or any similar domestic or foreign law or the rules and regulations promulgated thereunder concerning the employees of the Company or any of the Significant Subsidiaries. (nn) Each employee benefit plan, within the meaning of Section 3(3) of ERISA, that is maintained, administered or contributed to by the Company or any Subsidiary or any member of the Company’s “control group” (within the meaning of Section 414 of the Internal Revenue Code of 1986, as amended (the “Code”) for employees or former employees of the Company and its affiliates (“Plan”) has been maintained in material compliance with its terms and the requirements of any applicable statutes, orders, rules and regulations, including but not limited to ERISA and the Code. No “prohibited transaction,” within the meaning of Section 406 of ERISA or Section 4975 of the Code has occurred with respect to any such Plan excluding transactions effected pursuant to a statutory or administrative exemption. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, the Subsidiaries or any of their ERISA Affiliates. No “employee benefit plan” (as defined under ▇▇▇▇▇)

15 established or maintained by the Company, the Subsidiaries or any of their ERISA Affiliates, if such employee benefit plan were terminated, could have any “amount of unfunded benefit liabilities” (as defined under ERISA). Neither the Company, the Subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (A) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan,” or (B) Sections 412, 4971, 4975 or 4980B of the Code. Each employee benefit plan established or maintained by the Company, the Subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, which could cause the loss of such qualification. With respect to each Plan subject to Title IV of ERISA, the minimum funding standard of Section 302 of ERISA or Section 412 of the Code, as applicable, has been satisfied (without taking into account any waiver thereof or extension of any amortization period) and is reasonably expected to be satisfied in the future (without taking into account any waiver thereof or extension of any amortization period) and the fair market value of the assets under each Plan exceeds the present value of all benefits accrued under such Plan (determined based on those assumptions used to fund such Plan). There is no pending audit or investigation by the Internal Revenue Service, the U.S. Department of Labor, the Pension Benefit Guaranty Corporation or any other governmental agency or any foreign agency. (oo) The Company and its Subsidiaries have good and marketable title in fee simple to all real property owned by the Company and its Subsidiaries and good title to all other properties owned by them, in each case, free and clear of all mortgages, pledges, liens, security interests, claims, restrictions or encumbrances of any kind except such as (A) are described in the Registration Statement, the Time of Sale Prospectus and the Prospectus or (B) do not materially affect the value of such property and do not interfere in any material respect with the use made and proposed to be made of such property by the Company or any Subsidiary. All of the leases and subleases under which the Company or any of its Subsidiaries holds properties described in the Registration Statement, the Time of Sale Prospectus and the Prospectus, are in full force and effect and are held under valid, subsisting and enforceable leases, and neither the Company nor any Subsidiary has received any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company or any Subsidiary under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company or such Subsidiary to the continued possession of the leased or subleased premises under any such lease or sublease. (pp) Neither the Company nor any of the Subsidiaries, nor any affiliates of the Company or its Subsidiaries, has taken, directly, or indirectly, and neither the Company nor any of the Subsidiaries, nor any affiliates of the Company or its Subsidiaries, will take, directly or indirectly, any action designed to cause or result in, or which constitutes or could reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company or any “reference security” (as defined in Rule 100 of Regulation M under the Exchange Act) to facilitate the sale or resale of the Securities or otherwise, and has taken no action which would directly or indirectly violate Regulation M under the Exchange Act.

16 (qq) No relationship, direct or indirect, exists between or among the Company or any of its Subsidiaries, on the one hand, and the directors, officers, shareholders, customers or suppliers of the Company or any of its Subsidiaries, on the other, that is required by the Securities Act or the rules and regulations promulgated under the Securities Act to be described in the Registration Statement and/or the Prospectus and that is not so described. (rr) Except as disclosed in the Registration Statement, the Time of Sale Prospectus and the Prospectus, the Company (A) does not have any material lending or other relationship with any bank or lending affiliate of any Underwriter and (B) does not intend to use any of the proceeds from the sale of the Securities to repay any outstanding debt owed to any affiliate of any Underwriter. (ss) Except in each case as otherwise disclosed in the Registration Statement, the Time of Sale Prospectus or the Prospectus, no Subsidiary of the Company is currently prohibited, directly or indirectly, under any agreement or other instrument to which it is a party or is subject, from paying any dividends to the Company, from making any other distribution on such Subsidiary’s capital stock, from repaying to the Company any loans or advances to such Subsidiary from the Company or from transferring any of such Subsidiary’s properties or assets to the Company or any other Subsidiary of the Company. (tt) Other than as contemplated by this Agreement, there is no broker, finder or other party that is entitled to receive from the Company or any Subsidiary any brokerage or finder’s fee or any other fee, commission or payment as a result of the transactions contemplated by this Agreement. Other than as contemplated by this Agreement, no person has the right to act as a financial advisor to the Company in connection with the offer and sale of the Securities. (uu) Any and all currently outstanding material swaps, caps, floors, futures, forward contracts, option agreements (other than options issued under the Company’s shareholder-approved benefit plans) and other derivative financial instruments, contracts or arrangements, whether entered into for the account of the Company or one of its Subsidiaries or for the account of a customer of the Company or one of its Subsidiaries, were entered into in the ordinary course of business and in accordance with applicable laws, rules, regulations and policies of all applicable regulatory agencies and with counterparties believed by the Company to be financially responsible. The Company and each of its Subsidiaries have duly performed in all material respects all of their obligations thereunder to the extent that such obligations to perform have accrued, and there are no breaches, violations or defaults or allegations or assertions of such by any party thereunder except as would not, singly or in the aggregate, reasonably be expected to have a Material Adverse Effect. (vv) Except as would not have a Material Adverse Effect, neither the Company nor any Significant Subsidiary has sent or received any communication regarding termination of, or intent not to renew, any of the contracts or agreements referred to or described in the Time of Sale Prospectus and Prospectus, or referred to or described in, or

17 filed as an exhibit to, the Time of Sale Prospectus and Prospectus, and no such termination or non-renewal has been threatened by the Company or any Significant Subsidiary or, to the Company’s knowledge, any other party to any such contract or agreement; and there are no contracts or documents of the Company or any of the Significant Subsidiaries that are required to be described in the Time of Sale Prospectus and the Prospectus or to be filed as exhibits thereto by the Securities Act or by the rules and regulations of the Commission thereunder that have not been so described and filed. (ww) There is no transaction, arrangement or other relationship between the Company or any of its Subsidiaries and an unconsolidated or other off-balance sheet entity which is required to be disclosed in the Registration Statement, the Time of Sale Prospectus and the Prospectus (other than as disclosed therein). (xx) The application of the proceeds received by the Company from the issuance, sale and delivery of the Securities as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus will not violate Regulation T, U or X of the Board of Governors of the Federal Reserve System (together with the Federal Reserve Bank of Philadelphia, as applicable, the “Federal Reserve”) or any other regulation of the Federal Reserve. (yy) The Company and each Subsidiary is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which they are engaged including, but not limited to, policies covering real and personal property owned or leased by the Company and each Subsidiary against theft, damage, destruction, acts of vandalism and earthquakes; neither the Company nor any of its Subsidiaries has been refused any insurance coverage sought or applied for; and the Company has no reason to believe that it or any Subsidiary will not be able to renew their existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect. All such insurance is fully in force as of the date hereof. The Company and each of its Subsidiaries are in compliance with the terms of such policies and instruments in all material respects; and there are no material claims by the Company or any of its Subsidiaries under any such policy or instrument as to which any insurance company is denying liability or defending under a reservation of rights clause. (zz) The Company and its Subsidiaries possess such permits, licenses, approvals, registrations, memberships, consents and other authorizations issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct the business now operated by them (collectively, “Governmental Licenses”); the Company and its Subsidiaries are in compliance with the terms and conditions of all such Governmental Licenses, except where the failure to possess such Governmental Licenses or to so comply would not, singly or in the aggregate, have a Material Adverse Effect and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination of any such Governmental License or result in any other material impairment of the rights of any such Governmental License; all of the Governmental Licenses are valid and in full force and effect; and neither the Company

18 nor any of its Subsidiaries has received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses. Neither the Company nor any of its Subsidiaries has failed to file with applicable regulatory authorities any material statement, report, information or form required by any applicable law, regulation or order, all such filings were in material compliance with applicable laws when filed and no material deficiencies have been asserted by any regulatory commission, agency or authority with respect to any such filings or submissions. (aaa) The Company has been duly registered as, and meets in all material respects the applicable requirements for qualification as, a bank holding company and has elected to be treated as a financial holding company under the applicable provisions of the Bank Holding Company Act of 1956, as amended. The activities of the Subsidiaries are permitted of Subsidiaries of a financial holding company under applicable law and the rules and regulations of the Federal Reserve set forth in Title 12 of the Code of Federal Regulations. (bbb) Except as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus, the Company and the Bank are in compliance in all material respects with all applicable laws, rules and regulations (including, without limitation, all applicable regulations and orders) of, or agreements with, the Federal Reserve, the Federal Deposit Insurance Corporation (the “FDIC”), the Consumer Financial Protection Bureau and the Pennsylvania Department of Banking and Securities, as applicable (collectively, the “Bank Regulatory Authorities”), the Equal Credit Opportunity Act, the Fair Housing Act, the Truth in Lending Act, the Community Reinvestment Act (the “CRA”), the Home Mortgage Disclosure Act, the Bank Secrecy Act and Title III of the USA Patriot Act, to the extent such laws or regulations apply to the Company or the Bank, as applicable. The Company and the Bank have no knowledge of any facts and circumstances, and have no reason to believe that any facts or circumstances exist, that could cause the Bank (A) to be deemed not to be in satisfactory compliance with the CRA and the regulations promulgated thereunder or to be assigned a CRA rating by federal or state banking regulators of lower than “satisfactory,” or (B) except as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus, to be deemed to be operating in violation, in any material respect, of the Bank Secrecy Act of 1970 as amended by the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (or otherwise known as the “Currency and Foreign Transactions Reporting Act”), the USA Patriot Act (or otherwise known as “Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001”) or any order issued with respect to the Anti-Money Laundering Laws (as defined below). As of December 31, 2024, each of the Company and the Bank met or exceeded the standards necessary to be considered “well capitalized” under the Federal Reserve’s Regulation Y and regulatory framework for prompt corrective action, respectively. The Bank has a Community Reinvestment Act rating of at least “Satisfactory.” The Bank has been duly chartered, is validly existing or subsisting under the laws of the Commonwealth of Pennsylvania and holds the requisite authority to do business as a state-chartered bank with banking powers under the laws of the Commonwealth of Pennsylvania. The Bank is the only depository institution subsidiary of the Company, and

19 the Bank is a member of the Federal Reserve System and a member in good standing of the Federal Home Loan Bank System. The activities of the Bank are permitted under the laws and regulations of Pennsylvania. Since December 31, 2020, the Company, the Bank and each of their Subsidiaries have filed all material reports, registrations and statements, together with any required amendments thereto, that it was required to file with the Bank Regulatory Authorities and any other applicable federal or state banking authorities. All such reports and statements filed with any such regulatory body or authority are collectively referred to herein as the “Company Reports.” As of their respective dates, the Company Reports complied as to form in all material respects with all the rules and regulations promulgated by the Bank Regulatory Authorities and any other applicable federal or state banking authorities, as the case may be. Except as disclosed in the Registration Statement, the Time of Sale Prospectus and the Prospectus, none of the Company, the Bank nor any of their respective subsidiaries is a party or subject to any formal or informal agreement, memorandum of understanding, consent decree, directive, cease-and-desist order, order of prohibition or suspension, written commitment, supervisory agreement or other written statement as described under 12 U.S.C. 1818(u) with, or order issued by, or has adopted any board resolutions at the request of, the Bank Regulatory Authorities or any other bank regulatory authority that restricts materially the conduct of its business, or in any manner relates to its capital adequacy, its credit policies or its management, nor have any of them been advised by any Bank Regulatory Authority that it is contemplating issuing or requesting (or is considering the appropriateness of issuing or requesting) any such order, decree, agreement, memorandum of understanding, extraordinary supervisory letter, commitment letter or similar submission, or any such board resolutions or that imposes any restrictions or requirements not generally applicable to bank holding companies or commercial banks. There is no unresolved violation, criticism or exception by any Bank Regulatory Authority with respect to any examination of the Company, the Bank or any of the Company’s other Subsidiaries, which would reasonably be expected to result in a Material Adverse Effect. (ccc) The deposit accounts of the Bank are insured by the FDIC up to applicable legal limits, the Bank has paid all premiums and assessments required by the FDIC and the regulations thereunder, and no proceeding for the termination or revocation of such insurance is pending or, to the knowledge of the Company, threatened. (B) The Bank represents and warrants to each Underwriter at the date hereof, the Applicable Time, the Closing Time and any Date of Delivery, and agrees with each Underwriter, as follows: (a) The Bank has been duly chartered and is presently subsisting as a state- chartered bank in good standing under the laws of Pennsylvania, and has been duly qualified as a foreign bank for the transaction of business and is in good standing under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification or is subject to no material liability or disability by reason of the failure to be so qualified in any such other jurisdiction; (b) Neither the Bank nor any of its subsidiaries is (A) in violation of its articles or certificate of incorporation, bylaws or other organizational or governing

20 documents, (B) in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan agreement, note, lease or other agreement or instrument to which the Bank or any of its subsidiaries is a party or by which any of them is bound or to which any of the property or assets of the Bank or any of its subsidiaries is subject (collectively, the “Bank Instruments”) or (C) in violation of any statute, law, rule, regulation, order, decree of any court or governmental agency or body having jurisdiction over the Bank or any of its subsidiaries; in the case of clauses (B) and (C), except for defaults or violations that could not, singly or in the aggregate, reasonably be expected to result in a material adverse effect (i) on the general affairs, condition (financial or otherwise), business, properties, prospects, management, financial position, shareholders’ equity, assets, liabilities or results of operations, of the Bank and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business or (ii) in the ability of the Bank to perform its obligations under this Agreement (each of (i) and (ii) a “Bank MAE”); and (c) The execution, delivery and performance of this Agreement by the Bank, compliance by the Bank with all of the provisions of this Agreement and the consummation of the transactions herein contemplated do not and will not contravene, conflict with, or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any Bank Instrument, nor does or will any such action contravene, conflict with or result in a breach or violation of any of the terms or provisions of the articles of incorporation or bylaws of the Bank or any statute, order, law, rule, regulation or decree of any court or governmental agency or body having jurisdiction over the Bank or any of its subsidiaries or any of their properties, except for contraventions, conflicts, breaches or violations of any Bank Instrument or violations of statutes, orders, laws, rules, regulations or decrees that could not, singly or in the aggregate, reasonably be expected to result in a Bank MAE. (d) This Agreement has been duly authorized, executed and delivered by the Bank. (C) Any certificate signed by any officer of the Company or any of its Subsidiaries delivered to the Representative or to counsel for the Underwriters shall be deemed a representation and warranty by the Company to each Underwriter as to the matters covered thereby. 2. Agreements to Sell and Purchase. The Company hereby agrees to sell to the several Underwriters, and each Underwriter, upon the basis of the representations and warranties herein contained, but subject to the terms and conditions hereinafter stated, agrees, severally and not jointly, to purchase from the Company the respective numbers of Firm Shares set forth in Schedule I hereto opposite its name at the purchase price of $65.075 per share (the “Purchase Price”). On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to sell to the Underwriters the Additional Shares, and the Underwriters shall have the right to purchase, severally and not jointly, up to the number of Additional Shares set forth in Schedule I hereto at the

21 Purchase Price, provided, however, that the amount paid by the Underwriters for any Additional Shares shall be reduced by an amount per share equal to any dividends declared by the Company and payable on the Firm Shares but not payable on such Additional Shares. The Representatives may exercise this right on behalf of the Underwriters in whole or from time to time in part by giving written notice not later than 30 days after the date of the Prospectus. Any exercise notice shall specify the number of Additional Shares to be purchased by the Underwriters and the date on which such shares are to be purchased. Each purchase date must be at least one business day after the written notice is given and may not be earlier than the closing date for the Firm Shares or later than ten business days after the date of such notice. Additional Shares may be purchased as provided in Section 4 hereof solely for the purpose of covering sales of shares in excess of the number of the Firm Shares. On each day, if any, that Additional Shares are to be purchased (an “Option Closing Date”), each Underwriter agrees, severally and not jointly, to purchase the number of Additional Shares (subject to such adjustments to eliminate fractional shares as the Representatives may determine) that bears the same proportion to the total number of Additional Shares to be purchased on such Option Closing Date as the number of Firm Shares set forth in Schedule I hereto opposite the name of such Underwriter bears to the total number of Firm Shares. 3. Public Offering. The Company is advised by the Representatives that the Underwriters propose to make a public offering of their respective portions of the Shares as soon after the Registration Statement and this Agreement have become effective as in the Representatives’ judgment is advisable. The Company is further advised by the Representatives that the Shares are to be offered to the public upon the terms set forth in the Prospectus. 4. Payment and Delivery. Payment for the Firm Shares shall be made to the Company in Federal or other funds immediately available in New York City against delivery of such Firm Shares for the respective accounts of the several Underwriters at 10:00 a.m., New York City time, on September 5, 2025 or at such other time on the same or such other date, not later than the fifth business day thereafter, as may be designated in writing by the Representatives. The time and date of such payment are hereinafter referred to as the “Closing Date.” Payment for any Additional Shares shall be made to the Company in Federal or other funds immediately available in New York City against delivery of such Additional Shares for the respective accounts of the several Underwriters at 10:00 a.m., New York City time, on the date specified in the corresponding notice described in Section 2 or at such other time on the same or on such other date, in any event not later than the tenth business day thereafter, as may be designated in writing by the Representatives. The Firm Shares and Additional Shares shall be registered in such names and in such denominations as the Representatives shall request not later than one full business day prior to the Closing Date or the applicable Option Closing Date, as the case may be. The Firm Shares and Additional Shares shall be delivered to the Representatives on the Closing Date or an Option Closing Date, as the case may be, for the respective accounts of the several Underwriters, with any transfer taxes payable in connection with the

22 transfer of the Shares to the Underwriters duly paid, against payment of the Purchase Price therefor. 5. Conditions to the Underwriters’ Obligations. The several obligations of the Underwriters are subject to the following conditions: (a) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date: (i) no order suspending the effectiveness of the Registration Statement shall be in effect, and no proceeding for such purpose or pursuant to Section 8A under the Securities Act shall be pending before or threatened by the Commission; (ii) there shall not have occurred any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded any of the securities of the Company or any of its Subsidiaries by any “nationally recognized statistical rating organization,” as such term is defined in Section 3(a)(62) of the Exchange Act; and (iii) there shall not have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations of the Company and its subsidiaries, taken as a whole, from that set forth in the Time of Sale Prospectus that, in the Representatives’ judgment, is material and adverse and that makes it, in the Representatives’ judgment, impracticable to market the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus. (b) The Underwriters shall have received on the Closing Date a certificate, dated the Closing Date and signed by an executive officer of the Company, to the effect set forth in Sections 5(a)(i) and 5(a)(ii) above and to the effect that the representations and warranties of the Company contained in this Agreement are true and correct as of the Closing Date and that the Company has complied with all of the agreements and satisfied all of the conditions on its part to be performed or satisfied hereunder on or before the Closing Date. The officer signing and delivering such certificate may rely upon the best of his or her knowledge as to proceedings threatened. (c) The Underwriters shall have received on the Closing Date an opinion and negative assurance letter of ▇▇▇▇▇▇▇▇ Ronon ▇▇▇▇▇▇▇ & ▇▇▇▇▇, LLP, outside counsel for the Company, dated the Closing Date, in the form and substance reasonably satisfactory to the Underwriters.

The opinion of ▇▇▇▇▇▇▇▇ Ronon ▇▇▇▇▇▇▇ & ▇▇▇▇▇, LLP described in Section 5(c) above shall be rendered to the Underwriters at the request of the Company and shall so state therein. (e) The Underwriters shall have received, on each of the date hereof and the Closing Date, a letter dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to the Underwriters, from Deloitte LLP, independent public accountants, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in the Registration Statement, the Time of Sale Prospectus and the Prospectus; provided that the letter delivered on the Closing Date shall use a “cut-off date” not earlier than the date hereof. (f) The “lock-up” agreements, each substantially in the form of Exhibit A hereto, between the Representatives and certain shareholders, officers and directors of the Company relating to restrictions on sales and certain other dispositions of shares of Common Stock or certain other securities, delivered to the Representatives on or before the date hereof, shall be in full force and effect on the Closing Date. (g) [Reserved]. (h) The several obligations of the Underwriters to purchase Additional Shares hereunder are subject to the delivery to the Representatives on the applicable Option Closing Date of the following: (i) a certificate, dated the Option Closing Date and signed by an executive officer of the Company, confirming that the certificate delivered on the Closing Date pursuant to Section 5(b) hereof remains true and correct as of such Option Closing Date; (ii) an opinion and negative assurance letter of ▇▇▇▇▇▇▇▇ Ronon ▇▇▇▇▇▇▇ & ▇▇▇▇▇, LLP, outside counsel for the Company, dated the Option Closing Date, relating to the Additional Shares to be purchased on such Option Closing Date and otherwise to the same effect as the opinion required by Section 5(c) hereof; (iii) an opinion and negative assurance letter of ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, counsel for the Underwriters, dated the Option Closing Date,

Covenants of the Company. The Company covenants with each Underwriter as follows: (a) To furnish to the Representatives, without charge, a signed copy of the Registration Statement (including exhibits thereto and documents incorporated by reference therein) and to deliver to each of the Underwriters prior to 10:00 a.m. New York City time on the business day next succeeding the date of this Agreement during and the period mentioned in Section 6(e) or 6(f) below, as many copies of the Time of Sale Prospectus, the Prospectus, any documents incorporated by reference therein and any supplements and amendments thereto or to the Registration Statement as the Representatives may reasonably request. (b) Before amending or supplementing the Registration Statement, the Time of Sale Prospectus or the Prospectus, to furnish to the Representatives a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which the Representatives reasonably objects, and to file with the Commission any prospectus required to be filed pursuant to Rule 424(b) under the Securities Act prior to the Closing Date. (c) To furnish to the Representatives a copy of each proposed free writing prospectus to be prepared by or on behalf of, used by, or referred to by the Company and not to use or refer to any proposed free writing prospectus to which the Representatives reasonably object. (d) Not to take any action that would result in an Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Underwriter that the Underwriter otherwise would not have been required to file thereunder. (e) If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and

25 any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law. (f) If, during such period after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses the Representatives will furnish to the Company) to which Shares may have been sold by the Representatives on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law. (g) To endeavor to qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request, provided that the Company shall not be required to (i) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject. (h) To make generally available to the Company’s security holders and to the Representatives as soon as practicable an earnings statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the date of this Agreement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder, which

26 obligation the Company may satisfy by filing such earnings statement with the Commission on its Electronic Data Gathering, Analysis and Retrieval System). (i) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company’s counsel and the Company’s accountants in connection with the registration and delivery of the Shares under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by, or referred to by the Company and amendments and supplements to any of the foregoing, including the filing fees payable to the Commission relating to the Shares (within the time required by Rule 456 (b)(1), if applicable), all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or Legal Investment memorandum in connection with the offer and sale of the Shares under state securities laws and all expenses in connection with the qualification of the Shares for offer and sale under state securities laws as provided in Section 6(g) hereof, including filing fees and the reasonable and documented fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky or Legal Investment memorandum, (iv) all filing fees and the reasonable and documented fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification of the offering of the Shares by the FINRA, (provided that the fees and disbursements of counsel payable by the Company pursuant to clauses (iii) and (iv) shall not, in the aggregate, exceed $25,000); (v) all costs and expenses incident to listing the Shares on the NYSE, (vi) the cost of printing certificates representing the Shares, (vii) the costs and charges of any transfer agent, registrar or depositary, (viii) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Shares, including, without limitation, expenses associated with the preparation or dissemination of any electronic road show, 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 with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants, and the cost of any aircraft chartered in connection with the road show, (ix) the document production charges and expenses associated with printing this Agreement and (x) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section. It is understood, however, that except as provided in this Section, Section 8 entitled “Indemnity and Contribution” and the last paragraph of Section 10 below, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, stock transfer taxes payable on resale of any of the Shares by them and any advertising expenses connected with any offers they may make.

27 (j) If the third anniversary of the initial effective date of the Registration Statement occurs before all the Shares have been sold by the Underwriters, prior to the third anniversary to file a new shelf registration statement and to take any other action necessary to permit the public offering of the Shares to continue without interruption; references herein to the Registration Statement shall include the new registration statement declared effective by the Commission. (k) If requested by the Representatives, to prepare a final term sheet relating to the offering of the Shares, containing only information that describes the final terms of the offering in a form consented to by the Representatives, and to file such final term sheet within the period required by Rule 433(d)(5)(ii) under the Securities Act following the date the final terms have been established for the offering of the Shares. (l) The Company will deliver to each Underwriter (or its agent), on the date of execution of this Agreement, a properly completed and executed Certification Regarding Beneficial Owners of Legal Entity Customers, together with copies of identifying documentation, and the Company undertakes to provide such additional supporting documentation as each Underwriter may reasonably request in connection with the verification of the foregoing Certification. (m) If at any time following the distribution of any Testing-the-Waters Communication that is a written communication within the meaning of Rule 405 under the Securities Act there occurred or occurs an event or development as a result of which such Testing-the-Waters Communication included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Testing-the-Waters Communication to eliminate or correct such untrue statement or omission. (n) The Company also covenants with each Underwriter that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ on behalf of the Underwriters, it will not, and will not publicly disclose an intention to, during the restricted period ending 90 days after the date of the Prospectus (the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise or (3) file any registration statement with the Commission relating to the offering of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock. The restrictions contained in the foregoing sentence shall not apply to (A) the Shares to be sold hereunder, (B) the issuance by the Company of shares of Common Stock upon the exercise of an option or warrant or the conversion of a security outstanding on the date

28 hereof as described in each of the Time of Sale Prospectus and Prospectus, (C) grants of compensatory equity-based awards made pursuant to compensatory equity-based plans as described in the Registration Statement, Time of Sale Prospectus and Prospectus, (D) any Common Stock issuable pursuant to any non-employee director stock compensation plan or program described in each of the Registration Statement, Time of Sale Prospectus and Prospectus, or (E) facilitating the establishment of a trading plan on behalf of a shareholder, officer or director of the Company pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Common Stock, provided that (i) such plan does not provide for the transfer of Common Stock during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such plan during the Restricted Period. 7. Covenants of the Underwriters. Each Underwriter, severally and not jointly, covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter. 8. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”), the Prospectus or any amendment or supplement thereto, or any Testing-the-Waters Communication, or arise out of, or are based upon, 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 arise out of, or are based upon, any such untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by the Underwriters through the Representatives consists of the information described as such in paragraph (b) below. (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

29 each person, if any, 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 such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, road show, or the Prospectus or any amendment or supplement thereto, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the following information in the Prospectus: the concession figure in the first sentence of the third paragraph and the information contained in the first two sentences and the seventh sentence in the eleventh paragraph concerning stabilization under the caption “Underwriting”. (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 Section 8(a) or 8(b), 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 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 or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party 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 Section 8(a), and by the Company, in the case of parties indemnified pursuant to Section 8(b). 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 fees and expenses of counsel as contemplated by the second and third sentences 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,

30 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. (d) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then 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 hand from the offering of the Shares or (ii) if the allocation provided by clause 8(d)(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 8(d)(i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters bear to the aggregate initial public offering price of the Shares set forth in the Prospectus. The relative fault of the Company on the one hand and the Underwriters on the other hand 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 or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. (e) The Company and the Underwriters agree that it would not be just or 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 that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) 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. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public 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

31 omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The 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. (f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares. 9. Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company, if after the execution and delivery of this Agreement and prior to or on the Closing Date or any Option Closing Date, as the case may be, (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE American, the NASDAQ Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange, the Chicago Board of Trade or other relevant exchanges, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States or other relevant jurisdiction shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the Representatives’ judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus. 10. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto. If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the

32 number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. 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, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder. 11. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the Underwriters with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares. (b) The Company acknowledges that in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement, any contemporaneous written agreements and prior written agreements (to the extent not superseded by this Agreement), if any, (iii) the Underwriters may have interests that differ from those of the Company, and (iv) none of the activities of the Underwriters in

33 connection with the transactions contemplated herein constitutes a recommendation, investment advice, or solicitation of any action by the Underwriters with respect to any entity or natural person. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares. 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 Section 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). “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). “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. “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 ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and the regulations promulgated thereunder. 13. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Counterparts may be delivered via facsimile, electronic mail (including any electronic signature complying with the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act or other applicable law, e.g., ▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. 14. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

34 15. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement. 16. Notices.
