(d) The sale of the Shares to be sold by the Selling Stockholders hereunder and the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby will not conflict with, result in the breach of any of the terms or conditions of, constitute a default under or violate, accelerate or permit the acceleration of any other similar right of any other party under any law, rule or regulation, or any agreement, lease, mortgage, note, bond, indenture, license or other document or undertaking, to which such Selling Stockholder is a party or by which such Selling Stockholder or its properties may be bound, nor will such execution, delivery and consummation violate any order, writ, injunction or decree of any Authority to which such Selling Stockholder or any of its properties is subject, the effect of any of which, either individually or in the aggregate, would affect the validity of the Shares to be sold by such Selling Stockholder or reasonably be expected to materially impact such Selling Stockholder’s ability to perform its obligations under this Agreement; and no consent, approval, authorization, order, registration or qualification of or with any such Authority is required for the performance by such Selling Stockholder of its obligations under this Agreement and the consummation by such Selling Stockholder of the transactions contemplated by this Agreement in connection with the Shares to be sold by such Selling Stockholder hereunder, except such consents, approvals, authorizations and orders as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on the Selling Stockholder’s ability to consummate the transactions contemplated by this Agreement. For the avoidance of doubt, the Selling Stockholders are not making any representations or warranties regarding compliance by the Company of the sale of Shares contemplated by this Agreement with any laws, rules, or regulations of the United States or the laws of any State, and the departments and agencies thereof, (i) governing the sale of securities, (ii) or the operation of banks and bank holding companies.

There is no action, suit, proceeding, claim, arbitration, litigation or investigation by any Selling Stockholder pending or threatened against any other person relating to the Shares owned by such Selling Stockholder.

(g) Neither the Company nor any of its representatives has been requested to or has provided any Selling Stockholder with any information or advice with respect to the Shares nor is such information or advice necessary or desired.

(h) Each Selling Stockholder acknowledges and understands that the Company may possess material nonpublic information that is not known to the Selling Stockholders that may impact the value of the Shares, and that the Company is not disclosing any information to the Selling Stockholders. Each Selling Stockholder understands, based on its experience, the disadvantage to which such Selling Stockholder is subject due to the disparity of information between the Company and the Selling Stockholders but nevertheless desires to enter into this transaction as a means to sell the Shares in a single large transaction rather than engage in sales in the open market over an extended period of time. Each Selling Stockholder agrees that the Company and its directors, officers, employees and agents shall have no liability to the Selling Stockholders, their affiliates, principals, stockholders, partners, employees, agents, grantors or beneficiaries, whatsoever due to or in connection with the Company’s use or non-disclosure of any such information or otherwise as a result of the transaction contemplated by this Agreement, and each Selling Stockholder hereby irrevocably waives any claim that it might have based on the failure of the Company to disclose such information.

(i) Each Selling Stockholder (either alone or together with its advisors) has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the transaction contemplated by this Agreement. Each Selling Stockholder is entering into this Agreement with a full understanding of all of the terms, conditions and risks and willingly assumes those terms, conditions and risks. Each Selling Stockholder has received (through electronic access on EDGAR) and carefully reviewed the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, all subsequent public filings of the Company with the Securities and Exchange Commission (the “SEC”), other publicly available information regarding the Company, and such other information that it and its advisers deem necessary to make its decision to enter into this Agreement and consummate the transactions contemplated hereby. Each Selling Stockholder has evaluated the merits and risks of the transactions under this Agreement based exclusively on its own independent review and consultations with such investment, legal, tax, accounting and other advisers as it deemed necessary, and has made its own decision concerning such transaction without reliance upon any express or implied representations or warranties of any nature made by or on behalf of the Company, whether or not any such representations, warranties or statements were made in writing or orally, except as expressly set forth for the benefit of the Selling Stockholders in this Agreement.

(j) The Company is relying on each Selling Stockholder’s representations, warranties, acknowledgments and agreements in this Agreement as a condition to proceeding with the transaction contemplated hereby, and without such representations, warranties and agreements, the Company would not enter into this Agreement or engage in such transaction.

4. Indemnification. Each party (the “Indemnifying Party”) shall indemnify, defend and hold harmless the other party and its affiliates and their respective representatives (the “Indemnified Party”) from and against any and all costs, expenses (including reasonable attorney’s fees), judgements, fines and losses incurred or sustained by, or imposed upon the Indemnified Party based upon, arising out of, with respect to or by reason of: (a) any inaccuracy in or breach of any of the representations or warranties of the Indemnifying Party contained in

-4-

this Agreement or in any certificate or instrument delivered by or on behalf of the Indemnifying Party pursuant to this Agreement; and (b) any breach or non-fulfillment of any covenant, agreement or obligation to be performed by the Indemnifying Party pursuant to this Agreement.

5. Publicity. Each of the Selling Stockholders and the Company agrees that it shall not, and that it shall cause its affiliates and representatives not to, (a) publish, release or file any initial press release or other public statement or announcement relating to the transactions contemplated by this Agreement (an “Initial Press Release”) before providing a copy of such release, statement or announcement to the other, and (b) after the date hereof, publish, release or file any future press release or other public statement or announcement relating to the transactions contemplated by this Agreement that is materially inconsistent with any such Initial Press Release; provided however, that each party acknowledges and agrees that any party shall be permitted to make any required filings with the SEC without providing a copy of such filing to any other party.

6. Notices. All notices, demands or other communications to be given or delivered under or by reason of the provisions of this Agreement will be in writing and will be deemed to have been given when delivered personally, mailed by certified or registered mail (return receipt requested and postage prepaid), sent via a nationally recognized overnight courier, or sent via email to the recipient.
