Ladies and Gentlemen:

Third Coast Bancshares, Inc., a Texas corporation (the “Company”), proposes to issue and sell to ▇▇▇▇▇▇▇▇ Inc., ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., and Deutsche Bank Securities, Inc. (together, the “Underwriters”) pursuant to the terms set forth herein (this “Agreement”), an aggregate of [•] shares (the “Firm Shares”) of the Company’s common stock, par value $1.00 per share (the “Common Stock”), in the amounts set forth opposite each Underwriter’s name on Schedule I hereto. The Company has also granted to the Underwriters an option to purchase from the Company up to an additional [•] shares of Common Stock (the “Option Shares”). The Firm Shares and the Option Shares are hereinafter referred to collectively as the “Shares.”

The Company has prepared and filed with the United States Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (File No. 333-260291), which includes a form of prospectus to be used in connection with the public offering and sale of the Shares. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, in the form in which it became effective under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations promulgated thereunder (the “Securities Act Regulations”), including any information contained in the prospectus filed as a part of the registration statement pursuant to Rule 424 of the Securities Act Regulations or otherwise deemed to be a part thereof at the time of effectiveness pursuant to Rule 430A or 430C of the Securities Act Regulations, is called the “Registration Statement.” If the Company files an abbreviated registration statement increasing the size of the offering pursuant to Rule 462(b) under the Securities Act (a “Rule 462(b) Registration Statement”), then the term “Registration Statement” herein shall be deemed to include the Rule 462(b) Registration Statement. The final prospectus (in the form first

used by the Underwriters to confirm sales of the Shares or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) that meets the requirements of Section 10(a) of the Securities Act is referred to herein as the “Prospectus.” Each prospectus in preliminary form (filed with the Commission pursuant to Rule 424(a) of the Securities Act Regulations, omitting certain information as permitted by Rule 430A(a) of the Securities Act Regulations) that describes the Shares and the offering thereof and is used prior to the filing of the Prospectus is referred to herein as a “preliminary prospectus.” The preliminary prospectus relating to the Shares that was included in the Registration Statement immediately prior to the Applicable Time (as defined below) is hereinafter called the “Pricing Prospectus.” “Pricing Disclosure Package” means the Pricing Prospectus, together with the Issuer Free Writing Prospectuses (as defined below), if any, listed on Schedule II hereto, and the pricing information conveyed orally to investors, and as set forth on Schedule II hereto. Any “issuer free writing prospectus” (as defined in Rule 433(h)(1) of the Securities Act Regulations) relating to the offering of the Shares contemplated hereunder is hereinafter called an “Issuer Free Writing Prospectus.”

The Company also has prepared and filed, in accordance with Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations promulgated thereunder (the “Exchange Act Regulations”), a registration statement on Form 8-A (File No. 001-[•]) to register the Common Stock under Section 12(b) of the Exchange Act.

As used in this Agreement:

The descriptions of the Company’s stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted thereunder, set forth in the Registration Statement, the Pricing Disclosure Package and the Prospectus accurately and fairly present in all material respects the information required to be shown with respect to such plans, arrangements, options and rights.

except, in the case of clauses (A) and (B), for such violations or defaults that would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect; and the execution, delivery and performance of this Agreement by the Company and the consummation of the transactions contemplated herein and in the Registration Statement by the Company (including the issuance and sale of the Shares and the use of the proceeds from the sale of the Shares as described in the Prospectus under the caption “Use of Proceeds”) and compliance by the Company with its obligations hereunder do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any Subsidiary pursuant to, the Agreements and Instruments (except for such conflicts, breaches, defaults or liens, charges or encumbrances that would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect); nor will such action result in any violation of the provisions of the Charter or Bylaws of the Company or the charter, bylaws or other organizational document of any Subsidiary; nor will such action result in any violation of any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any Subsidiary or any of their assets, properties or operations (except for such violations that would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect).

(xix) Absence of Labor Dispute. 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, manufacturers, 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 the Bank is engaged in any unfair labor practice; to the Company’s knowledge, no union organizing activities are currently taking place concerning the employees of the Company or the Bank; except for matters which would not, individually or in the aggregate, reasonably be expected to 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 the Bank 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 the Bank and (3) no union representation dispute currently existing concerning the employees of the Company or the Bank, and (B) 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 the Bank.

The Company and each of its Subsidiaries is in compliance in all material respects with all applicable laws, rules, regulations, orders, or enforcement actions by, or formal or informal agreements with, the Federal Reserve, the Federal Deposit Insurance Corporation (“FDIC”), the TDSML and any other applicable federal or state banking authorities (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 Currency and Foreign Transactions Reporting Act or Bank Secrecy Act of 1970 (“Bank Secrecy Act”) and Title III of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“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 has 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) to be deemed to be operating in violation, in any material respect, of the Bank Secrecy Act, the USA Patriot Act or any order issued with respect to the Anti-Money Laundering Laws (as defined below). As of the most recent quarter end, the Bank met or exceeded the standards necessary to be considered “well capitalized” under the regulatory framework for prompt corrective action of the Federal Reserve. The Bank is the only depository institution subsidiary of the Company and the Bank is a member in good standing of the Federal Home Loan Bank System and the Federal Reserve System. The activities of the Bank and its subsidiaries are permitted under the laws and regulations of the State of Texas and the United States of America. Since December 31, 2014, the Company, the Bank and each of their respective subsidiaries have filed all material reports, registrations and statements, together with any required amendments thereto, that were required to be filed with all Bank Regulatory 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. Except as disclosed in the Registration Statement, the Pricing Disclosure Package and the Prospectus, none of the Company, the Bank or 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 or commitments at the request of, any Bank Regulatory Authority, 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. 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, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

(xxviii) Environmental Laws. Except as described in the Registration Statement and except as would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect, (A) neither the Company nor any of its Subsidiaries is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products, asbestos-containing materials or mold (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”), (B) the Company and its Subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements, (C) there are no pending or, to the Company’s knowledge, threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any of its Subsidiaries and (D) there are no events or circumstances that would reasonably be expected to result in forming the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, against or affecting the Company or any of its Subsidiaries relating to Hazardous Materials or any Environmental Laws.

(xxix) ERISA. Each employee benefit plan, within the meaning of Section 3(3) of ERISA, each non-qualified deferred compensation plan or arrangement, and each non-qualified retirement plan or arrangement 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 ERISA) 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). With respect to each Plan that is funded and is a non-qualified deferred compensation plan or a non-qualified retirement plan, the fair market value of the assets under each Plan (including the cash value of any insurance policy used to fund the 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. For purposes of this Agreement, “ERISA Affiliate” means any trade or business (whether or not incorporated) that together with the Company or any Subsidiary is treated as a single employer under Section 414(b) or (c) of the Code or, solely for purposes of Section 302 of ERISA and Sections 412 and 430 of the Code, is treated as a single employer under Section 414(m) of the Code.

(xxx) Internal Control Over Financial Reporting. The Company and each of its Subsidiaries maintain a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act Regulations) that complies in all material respects with the requirements of the Exchange Act and has been designed by the Company’s principal executive officer and principal financial officer and is sufficient to provide reasonable assurance that (A) transactions are executed in accordance with management’s general or specific authorizations; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (C) access to assets is permitted only in accordance with management’s general or specific authorization; (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (E) any interactive data in eXtensible Business Reporting Language included in the Registration Statement is accurate and fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto. The Company and the Bank also comply in all material respects with the internal controls requirements of FDIC Regulations Part 363. Except as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, since the end of the Company’s most recent audited fiscal year, (i) there has been no material weakness in the Company’s internal control over financial reporting (whether or not remediated), (ii) there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting and (iii) the Company has not been advised of (a) any significant deficiencies in the design or operation of internal controls that could adversely affect the ability of the Company or any Subsidiary to record, process, summarize and report financial data, or any material weaknesses in the Company’s internal control over financial reporting, or (b) any fraud, whether or not material, that involves management or other employees who have a significant role in the internal controls of the Company and each of the Subsidiaries.

(xxxi) Disclosure Controls and Procedures. 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 weaknesses 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, there have been no changes in internal controls or in other factors that could significantly and adversely affect internal controls.

(xxxii) Compliance with the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act.

The charges, accruals and reserves on the books of the Company and the Subsidiaries in respect of any income and corporation tax liability for any years not finally determined are adequate to meet any assessments or re-assessments for additional income tax for any years not finally determined. Except as otherwise disclosed in the Registration Statement, the Pricing Disclosure Package and the Prospectus, there is no material tax deficiency that has been or would reasonably be expected to be asserted against the Company or any of its Subsidiaries or any of their respective properties or assets.

All such insurance is fully in force as of the date hereof.

Section 8. Indemnification.

(a) Indemnification of Underwriters by the Company and the Bank. The Company and the Bank, jointly and severally, agree to indemnify and hold harmless each Underwriter, its Affiliates, selling agents, officers, directors and partners and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, any Issuer Free Writing Prospectus, the Pricing Disclosure Package or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission in any preliminary prospectus, any Issuer Free Writing Prospectus, the Pricing Disclosure Package or the Prospectus (or any amendment or supplement thereto) of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 8(e) hereof) any such settlement is effected with the written consent of the Company;

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Underwriters), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or in any preliminary prospectus, any Issuer Free Writing Prospectus, the Pricing Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information. Notwithstanding the foregoing, the indemnification obligation of the Bank in this Section 8 shall be limited solely with respect to the Bank to the extent necessary if a governmental agency or body having jurisdiction over the Bank by written communication addressed to the Bank or its board of directors, including in connection with any examination of the Bank, informs the Bank or its board of directors that such governmental agency or body has determined that such indemnification violates Sections 23A or 23B of the Federal Reserve Act, as amended, or another law, rule, or regulation applicable to the Bank or the Company.

(b) Indemnification of Company, the Bank, Directors and Officers by the Underwriters. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, the Bank, and each of their directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 8(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or in any preliminary prospectus, any Permitted Written Testing-the-Waters Communication, and any Issuer Free Writing Prospectus, the Pricing Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(c) Indemnification for Directed Share Program. In connection with the offer and sale of the Directed Shares, the Company and the Bank, jointly and severally, agree to indemnify and hold harmless each Underwriter, its Affiliates, selling agents, officers and directors and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all loss, liability, claim, damage and expense (including, without limitation, any legal or other expenses reasonably incurred in connection with defending, investigating, or settling any such action or claim) as incurred by them (i) caused by the failure of any Directed Share Participant to pay for and accept delivery of Directed Shares which have been orally confirmed by the end of the first business day following the date of this Underwriting Agreement or (ii) related to, or arising out of or in connection with, the offering of the Directed Shares, other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of any Underwriter.

(d) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 8(a) or Section 8(b) hereof, counsel to the indemnified parties shall be selected by the Underwriters, and, in the case of parties indemnified pursuant to Section 8(c) hereof, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, that counsel to the indemnifying party shall not (except with the prior written consent of the indemnified party) also be counsel to the indemnified party. In any action the defense of which is assumed by the indemnifying party pursuant to this Agreement, an indemnified party shall have the right to participate in such action and to retain its own counsel at the expense of such indemnified party, except that the fees and expenses of such counsel shall be borne by the indemnifying party if (i) the indemnifying party and such indemnified party shall have mutually agreed in writing to the retention of such counsel, (ii) the indemnifying party shall have failed in a timely manner to assume the defense and employ counsel reasonably satisfactory to the indemnified party in such action, or (iii) the indemnified party reasonably determines that defenses may be available to the indemnified party which are not available to the indemnifying party or may not be consistent with the best interests of the indemnifying party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 8 or Section 9 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding 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.

(e) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 8(a)(ii) effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

Section 9. Contribution.

If the indemnification provided for in Section 8 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such

proportion as is appropriate to reflect the relative benefits received by the Company and the Bank, on the one hand, and the Underwriters, on the other hand, from the offering of the Shares pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Bank, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company and the Bank, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Shares pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Shares pursuant to this Agreement (before deducting expenses) received by the Company and the Bank, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Shares as set forth on the cover of the Prospectus.

The relative fault of the Company and the Bank, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company and the Bank or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Bank and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 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 Section 9. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 9 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting discount received by such Underwriter in connection with the Shares underwritten by it and distributed to the public, less any amounts previously paid by such Underwriter pursuant to Section 8(b).

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the number of Firm Shares set forth opposite their respective names in Schedule I hereto and not joint.

For purposes of this Section 9, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each Underwriter’s Affiliates, officers, directors and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. Notwithstanding the foregoing, the contribution obligation of the Bank in this Section 9 shall be limited solely with respect to the Bank to the extent necessary if a governmental agency or body having jurisdiction over the Bank by written communication addressed to the Bank or its board of directors, including in connection with any examination of the Bank, informs the Bank or its board of directors that such governmental agency or body has determined that such contribution violates Sections 23A or 23B of the Federal Reserve Act, as amended, or another law, rule, or regulation applicable to the Bank or the Company.

Section 10. Defaulting Underwriter.

(a) If any Underwriter or Underwriters default in its or their obligations to purchase Shares hereunder on the Closing Date or any Option Closing Date and the aggregate number of Shares that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Shares that the Underwriters are obligated to purchase on such Closing Date or Option Closing Date, as the case may be, the Underwriters may make arrangements satisfactory to the Company for the purchase of such Shares by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date or Option Closing Date, as the case may be, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Shares that such defaulting Underwriters agreed but failed to purchase on such Closing Date or Option Closing Date, as the case may be. If any Underwriter or Underwriters so default and the aggregate number of Shares with respect to which such default or defaults occur exceeds 10% of the total number of Shares that the Underwriters are obligated to purchase on such Closing Date or Option Closing Date, as the case may be, and arrangements satisfactory to the Underwriters and the Company for the purchase of such Shares by other persons are not made within 36 hours after such default, this Agreement will terminate, subject to the provisions of Section 12, without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 12. Nothing herein will relieve a defaulting Underwriter from liability for its default.

(b) In the event of any such default which does not result in a termination of this Agreement, either the Underwriters or the Company shall have the right to postpone the Closing Date or the relevant Option Closing Date, as the case may be, for a period not exceeding seven days, in order to effect any required changes to the Registration Statement or Prospectus or any other documents or arrangements. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

Section 11. Termination.

Notwithstanding anything herein contained, this Agreement (or the obligations of the several Underwriters with respect to any Option Shares which have yet to be purchased) may be terminated, subject to the provisions of Section 12, in the absolute discretion of the Underwriters, by notice given to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or the Option Closing Date, as the case may be, (a) trading generally on the New York Stock Exchange or on the Nasdaq shall have been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other governmental or regulatory authority, (b) trading of any securities of or guaranteed by the Company or any Subsidiary shall have been suspended on any exchange or in any over-the-counter market, (c) a general moratorium on commercial banking activities in New York shall have been declared by Federal or New York State authorities or a new restriction materially adversely affecting the distribution of the Firm Shares or the Option Shares, as the case may be, shall have become effective, (d) a material disruption has occurred in commercial banking or securities settlement or clearing service in the United States, (e) there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof, declaration by the United States of a national emergency, or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, or (f) there has occurred any other Material Adverse Effect, in each case the effect of which is such as to make it, in the judgment of the Underwriters, impracticable to market the Shares to be delivered on the Closing Date or Option Closing Date, as the case may be, or to enforce contracts for the sale of the Shares.

If this Agreement is terminated pursuant to this Section 11, such termination will be without liability of any party to any other party except as provided in Section 5 and Section 12 hereof; provided, that the provisions of Section 8 and Section 9 shall at all times be effective and shall survive such termination.

Section 12. Effect of Termination.

(a) The respective indemnities, agreements, representations, warranties and other statements of the Company and the Bank and their respective officers, and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company, the Bank, or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Shares.

(b) If this Agreement is terminated pursuant to Section 6, Section 10 or Section 11 or if for any reason the purchase of any of the Shares by the Underwriters is not consummated, the Company and the Bank shall remain responsible for the expenses to be paid or reimbursed by them pursuant to Section 5, the respective obligations of the Company and the Underwriters pursuant to Section 8 and Section 9 and the provisions of Section 10 and Section 11 shall remain in effect and, if any Shares have been purchased hereunder, the representations and warranties in Section 1 and all obligations under Section 5, Section 6, Section 8 and Section 9 shall also remain in effect.

(c) If this Agreement shall be terminated by the Underwriters, or any of them, under Section 6 or Section 11 or otherwise 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 any of the Company shall be unable to perform its obligations under this Agreement or any condition of the Underwriters’ obligations cannot be fulfilled, the Company agrees to 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 expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement or the offering contemplated hereunder, but subject to any limitations set forth in Section 5.

Section 13. Successors; Assigns.

This Agreement shall inure to the benefit of and be binding upon the Company, the Bank and the Underwriters, the officers and directors of the Company referred to herein, any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Shares from any Underwriter shall be deemed to be a successor or assign by reason merely of such purchase.

Section 14. Notices.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given upon receipt thereof by the recipient if mailed or transmitted by electronic mail or any other standard form of telecommunication.

State Tech. §§ 301-309), as amended from time to time, or other applicable law) or other transmission method, and the parties hereto agree that any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

Section 16. Governing Law.

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO SUCH STATE’S PRINCIPLES OF CONFLICTS OF LAWS.

Section 17. Miscellaneous.

(a) The parties hereby submit to the jurisdiction of and venue in the state and federal courts located in the City of New York, New York, in connection with any dispute related to this Agreement including, without limitation, any suit or proceeding arising out of or relating to this Agreement, any transaction contemplated hereby, the Pricing Prospectus, the Prospectus, Registration Statement, the offering of the Shares or any other matter contemplated hereby. The Company and the Bank irrevocably and unconditionally waive any objection to the laying of venue of any such suit or proceeding arising out of or relating to this Agreement, the Pricing Prospectus, the Prospectus, the Registration Statement, the offering of the Shares or any transactions contemplated hereby in any such court, and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

(b) The Company and the Bank each acknowledge and agree that (i) the purchase and sale of the Shares pursuant to this Agreement, including the determination of the public offering price of the Shares and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Bank on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or the Bank or any of their respective shareholders, creditors, employees or any other person, entity or party, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company or the Bank with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or the Bank on other matters) or any other obligation to the Company or the Bank except the obligations expressly set forth in this Agreement, (iv) none of the activities of the Underwriters in 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 except as expressly provided herein, and (v) each of the Company and the Bank has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company and the Bank severally agree that each will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or the Bank, in connection with such transaction or the process leading thereto.

(c) The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views, thoughts or opinions communicated to the Company by such Underwriters’ investment banking divisions. The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

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

(e) This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior agreements and understandings (whether written or oral) between the Company, the Bank and the Underwriters, or any of them, with respect to the subject matter hereof.

(F) THE COMPANY, THE BANK AND EACH OF THE UNDERWRITERS HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

(g) This Agreement may not be amended or modified unless in writing signed by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The headings herein are for convenience only and shall not affect the construction hereof.
