AGREEMENT

NOW, THEREFORE, in consideration of the mutual promises herein contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

Investar may at any time and without the approval of WFB change the method of effecting the business combination contemplated by this Agreement if and to the extent that it reasonably deems such a change to be necessary or advantageous; provided, however, that no such change will (i) alter the nature or reduce the amount of the consideration to be issued to Holders as Merger Consideration as currently contemplated in this Agreement, (ii) reasonably be expected to materially impede or delay consummation of the Merger, (iii) adversely affect the federal income tax treatment of Holders in connection with the Merger, or (iv) require submission to or approval of the Holders after this Agreement has been approved by the Holders. In the event that Investar elects to make such a change, the Parties agree to cooperate to execute appropriate documents to reflect the change.

ARTICLE III

MERGER CONSIDERATION; EXCHANGE PROCEDURES

Section 3.01 Merger Consideration. Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of the Parties or any shareholder of WFB:

(a) Each share of Investar Common Stock that is issued and outstanding immediately prior to the Effective Time will remain outstanding following the Effective Time and will be unchanged by the Merger.

(b) Each share of WFB Common Stock owned directly by Investar, WFB, or any of their respective Subsidiaries (excluding shares in trust accounts, managed accounts and the like for the benefit of customers or shares held as collateral for outstanding debt previously contracted) immediately prior to the Effective Time will be cancelled and retired at the Effective Time without any conversion thereof, and no payment will be made with respect thereto (the “WFB Cancelled Shares”).

(c) Subject to Section 3.03, each share of WFB Common Stock (excluding WFB Cancelled Shares and Dissenting Shares) issued and outstanding immediately prior to the Effective Time will cease to be outstanding and will be converted, in accordance with the terms of this Article III, into and exchanged for the right to receive (i) the Per-Share Stock Consideration and (ii) the Per-Share Cash Consideration (the “Per-Share Merger Consideration”).

(d) Notwithstanding anything in this Agreement to the contrary, each Holder will have such rights to dissent from the Merger and obtain payment of the fair value of his shares as are afforded to such Person by Chapter 10, Subchapter H of the Texas Business Organizations Code (“TBOC”). Each share of WFB Common Stock issued and outstanding immediately prior to the Effective Time, the holder of which has properly perfected such holder’s rights of appraisal by following the exact procedure required by under the TBOC, is referred to herein as a “Dissenting Share.” If any holder of Dissenting Shares will effectively withdraw or lose his appraisal rights under the applicable provisions of the TBOC, each such Dissenting Share will cease to be a Dissenting Share and will be deemed to have been converted into and to have become exchangeable for, the right to receive the Per-Share Merger Consideration for each of such holder’s Dissenting Shares without any interest thereon in accordance with the provisions of Section 3.01(d). WFB will give Investar (i) prompt notice of any written notices to exercise dissenters’ rights in respect of any shares of WFB Common Stock, attempted withdrawals of such notices and any other instruments served pursuant to the TBOC and received by WFB relating to dissenters’ rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under the TBOC. WFB will not, except with the prior written consent of Investar, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment.

Section 3.02 Rights as Shareholders; Stock Transfers. At the Effective Time, all shares of WFB Common Stock, when converted in accordance with Section 3.01, will no longer be outstanding and will automatically be cancelled and retired and will cease to exist, and each Certificate or Book-Entry Share previously evidencing such shares will thereafter represent only the right to receive (i) the Merger Consideration in accordance with this Article III and (ii) any dividends or distributions which the holder thereof has the right to receive under Section 3.07. At the Effective Time, the stock transfer books of WFB will be closed, and there will be no registration of transfers on the stock transfer books of WFB of shares of WFB Common Stock.

Section 3.03 Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of Investar Common Stock, and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger. Instead, after aggregating all shares converted with respect to each such former holder of WFB Common Stock, Investar will pay to each former holder of WFB Common Stock otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the volume-weighted average trading price of Investar Common Stock on NASDAQ for the five consecutive trading days ending on the last trading date preceding the Closing Date, by (ii) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Investar Common Stock which such holder would otherwise be entitled to receive under Section 3.01(c).

Section 3.04 Plan of Reorganization. It is intended that the Merger and the Bank Merger will each qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement will constitute a “plan of reorganization” as that term is used in Sections 354 and 361 of the Code for each of the Merger and the Bank Merger.

Section 3.05 Exchange Procedures. Prior to the Effective Time, Investar will appoint the Exchange Agent for the payment and exchange of the Merger Consideration. Investar will cause as promptly as practicable after the Effective Time, but in no event later than ten (10) Business Days after the Closing Date, the Exchange Agent to mail or otherwise cause to be delivered to each former holder of WFB Common Stock appropriate and customary transmittal materials, which will specify that delivery will be effected, and risk of loss and title to the Certificates or Book-Entry Shares will pass, only upon delivery of the Certificates or Book-Entry Shares to the Exchange Agent, as well as instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for the Per Share Merger Consideration as provided for in this Agreement (the “Letter of Transmittal”).

Section 3.06 Deposit and Delivery of Merger Considerati.

(a) At or before the Effective Time, Investar will deposit with the Exchange Agent, for the benefit of the Holders, the Cash Consideration and evidence of shares in book entry representing the number of shares of Investar Common Stock in the Exchange Pool. Upon proper surrender of a Certificate or Book-Entry Shares for exchange and cancellation to the Exchange Agent, together with such Letter of Transmittal, properly completed and executed, and such other documents as may reasonably be required by the Exchange Agent or Investar, such former holder of WFB Common Stock will be entitled to receive the aggregate Per-Share Merger Consideration to which such former holder will have become entitled to receive in accordance with, and subject to, Section 3.01(c), of which the Per-Share Stock Consideration will be issued in book entry form. In the event any Certificate will have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if requested by Investar or the Exchange Agent, the posting by such person of a bond in such amount as Investar or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent or Investar, as applicable, will issue in exchange for such lost, stolen or destroyed Certificate the aggregate Per-Share Merger Consideration to which such former holder will have become entitled to receive in accordance with, and subject to, Section 3.01(c), of which the Per-Share Stock Consideration will be issued in book entry form.

(b) Any portion of the Merger Consideration that remains unclaimed by the shareholders of WFB for one (1) year after the Effective Time will be delivered by the Exchange Agent to Investar. Any former shareholder of WFB who has not theretofore complied with this Section 3.06 will thereafter look only to Investar for the Merger Consideration and any dividends or distributions on the Investar Common Stock deliverable to such former holder in respect of each share of WFB Common Stock such holder held immediately prior to the Effective Time, as determined pursuant to this Agreement, in each case without any interest thereon. If outstanding Certificates or Book-Entry Shares for shares of WFB Common Stock are not surrendered or the payment for them is not claimed prior to the date on which such shares of Investar Common Stock would otherwise escheat to or become the property of any governmental unit or agency, the unclaimed items will, to the extent permitted by the law of abandoned property and any other applicable Law, become the property of Investar (and to the extent not in its possession will be delivered to it), free and clear of all claims or interest of any Person previously entitled to such property. Neither the Exchange Agent nor any Party will be liable to any former shareholder of WFB for any amounts delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. Investar and the Exchange Agent will be entitled to rely upon the stock transfer books of WFB to establish the identity of those Persons entitled to receive the Merger Consideration specified in this Agreement, which books will be conclusive with respect thereto. In the event of a dispute with respect to ownership of any shares of WFB Common Stock represented by any Certificate or Book-Entry Share, Investar and the Exchange Agent will be entitled to tender to the custody of any court of competent jurisdiction any Merger Consideration represented by such Certificate or Book-Entry Share and file legal proceedings interpleading all parties to such dispute, and will thereafter be relieved with respect to any claims thereto.

(c) Investar or the Exchange Agent, as applicable, will be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any former holder of WFB Common Stock such amounts as Investar is required to deduct and withhold under applicable Law. Any amounts so deducted and withheld will be remitted to the appropriate Governmental Authority and upon such remittance will be treated for all purposes of this Agreement as having been paid to such former holder in respect of which such deduction and withholding was made by Investar or the Exchange Agent, as applicable.

Section 3.07 Rights of Certificate Holders after the Effective Time.

(a) All shares of Investar Common Stock to be issued pursuant to the Merger will be deemed issued and outstanding as of the Effective Time and if ever a dividend or other distribution is declared by Investar in respect of the Investar Common Stock, the record date for which is at or after the Effective Time, that declaration will include dividends or other distributions in respect of all shares of Investar Common Stock issuable pursuant to this Agreement. No dividends or other distributions in respect of the Investar Common Stock will be paid to any holder of any unsurrendered Certificate or Book-Entry Share until such Certificate or Book-Entry Share is surrendered for exchange in accordance with this Article III. Subject to the effect of applicable Laws, following surrender of any such Certificate or Book-Entry Share, there will be issued and/or paid to the holder of shares of Investar Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such shares of Investar Common Stock and not paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such shares of Investar Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender.

(b) If any shares of Investar Common Stock are to be issued in a name other than that in which the Certificate(s) surrendered in exchange therefor is or are registered, it will be a condition of the issuance thereof that the Certificate(s) so surrendered will be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the Person requesting such exchange will pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of shares of Investar Common Stock in any name other than that of the registered holder of the Certificate(s) surrendered, or required for any other reason, or will establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

Section 3.08 Anti-Dilution Provisions. If, prior to the Effective Time, the number of shares of Investar Common Stock issued and outstanding will be increased or decreased, or changed into or exchanged for a different number of kind of shares or securities, in any such case as a result of a stock split, reverse stock split, stock combination, stock dividend, recapitalization, reclassification, reorganization or similar transaction, or there will be any extraordinary dividend or distribution with respect to such stock, and the record date therefor will be prior to the Effective Time, an appropriate and proportionate adjustment will be made to the Per-Share Stock Consideration to give holders of WFB Common Stock the same economic effect as contemplated by this Agreement prior to such event.

Each WFB Benefit Plan which is intended to be qualified under Section 401(a) of the Code (“WFB 401(a) Plan”) has received a favorable determination letter from the IRS or is entitled to rely on a favorable opinion or advisory letter from the IRS, and, to WFB’s Knowledge, there is not any circumstance that could reasonably be expected to result in revocation of any such favorable determination, opinion or advisory letter, and nothing has occurred that would be expected to result in the WFB 401(a) Plan ceasing to be qualified under Section 401(a) of the Code. All WFB Benefit Plans have been administered in all material respects in accordance with their terms. There is no pending or, to WFB’s Knowledge, threatened litigation or regulatory action relating to the WFB Benefit Plans. Neither WFB nor any of its Subsidiaries has engaged in a transaction with respect to any WFB Benefit Plan that could reasonably be expected to subject WFB or any of its Subsidiaries to a tax or penalty under Section 4975 of the Code or Section 502(i) of ERISA.

There are no audits, inquiries, investigations, or proceedings pending or, to WFB’s Knowledge, threatened by any Governmental Authority, or participant claims (other than claims for benefits in the normal course of business), with respect to any WFB Benefit Plan. Neither WFB nor any administrator or fiduciary of any WFB Benefit Plan (or any agent of any of the foregoing) that is an employee of WFB has engaged in any transaction, or acted or failed to act in any manner with respect to any WFB Benefit Plan that could subject it to any direct or indirect material liability (by indemnity or otherwise) for breach of any fiduciary, co-fiduciary, or other duty under ERISA.

WFB has not contributed to (or been obligated to contribute to) a “multiple employer plan” within the meaning of ERISA Sections 4063 or 4064 or Code Section 413(c) at any time.

(h) Except as otherwise provided for in this Agreement or as set forth in WFB Disclosure Schedule Section 4.15(h), neither the execution of this Agreement, shareholder approval of this Agreement or consummation of any of the transactions contemplated by this Agreement (individually or in conjunction with any other event) will (i) entitle any WFB Employee to retention or other bonuses, non-competition payments, or any other payment, (ii) entitle any WFB Employee to severance pay or any increase in severance pay, (iii) accelerate the time of payment or vesting (except as required by Law) or trigger any payment or funding (through a grantor trust or otherwise) of compensation or benefits under or increase the amount payable under any of the WFB Benefit Plans, (iv) result in any breach or violation of, or a default under, any of the WFB Benefit Plans, (v) result in any payment of any amount that would, individually or in combination with any other such payment, be an excess “parachute payment” to a “disqualified individual” as those terms are defined in Section 280G of the Code, or (vi) limit or restrict the right of WFB or, after the consummation of the transactions contemplated hereby, Investar or any of its Subsidiaries, to merge, amend or terminate any of the WFB Benefit Plans.

Investar and WFB will use their commercially reasonable efforts to cooperate to hold the Investar Meeting and WFB Meeting as soon as reasonably practicable (subject to applicable notice requirements) after the Registration Statement is declared effective, and to set the same record date for each such meeting.

(b) Except to the extent provided otherwise in Section 6.09, the board of directors of WFB will at all times prior to and during the WFB Meeting recommend approval of this Agreement by the shareholders of WFB and the transactions contemplated hereby (including the Merger) and any other matters required to be approved by WFB’s shareholders for consummation of the Merger and the transactions contemplated hereby (the “WFB Recommendation”) and will not withhold, withdraw, amend, modify, change or qualify such recommendation in a manner adverse in any respect to the interests of Investar or take any other action or make any other public statement inconsistent with such recommendation and the Joint Proxy Statement/Prospectus will include the WFB Recommendation. In the event that there is present at such meeting, in person or by proxy, sufficient favorable voting power to secure the Requisite WFB Shareholder Approval, WFB will not adjourn or postpone the WFB Meeting unless WFB is advised by counsel that failure to do so would result in a breach of the fiduciary duties of the board of directors of WFB. WFB will keep Investar updated with respect to the proxy solicitation results in connection with the WFB Meeting as reasonably requested by Investar.

Section 6.05 Registration Statement; Joint Proxy Statement/Prospectus; Nasdaq Listing.

(a) Investar and WFB agree to cooperate in the preparation of the Registration Statement. WFB will use its reasonable best efforts to promptly deliver to Investar such information with respect to WFB and its Subsidiaries, their respective affiliates and the respective holders of their capital stock as may be required in order to prepare and file the Registration Statement, and any other report required to be filed by Investar with the SEC, in each case, in compliance in all material respects with applicable Laws, and will, as promptly as practicable following execution of this Agreement, prepare and deliver drafts of such information to Investar to review. Subject to WFB’s cooperation as provided in this Section 6.05(a), Investar will file with the SEC the Registration Statement. Each of Investar and WFB agree to use their respective commercially reasonable efforts to cause the Registration Statement to be declared effective by the SEC as promptly as reasonably practicable after the filing thereof and to maintain such effectiveness for as long as necessary to consummate the Merger and the other transactions contemplated by this Agreement. Investar also agrees to use commercially reasonable efforts to obtain any necessary state securities Law or “blue sky” permits and approvals required to carry out the transactions contemplated by this Agreement. WFB agrees to cooperate with Investar and ▇▇▇▇▇▇▇▇’s counsel and accountants in requesting and obtaining appropriate opinions, consents and letters from WFB’s independent auditors in connection with the Registration Statement and the Joint Proxy Statement/Prospectus. After the Registration Statement is declared effective under the Securities Act, WFB, at its own expense, will promptly mail or cause to be mailed the Joint Proxy Statement/Prospectus to its shareholders.

(b) The Joint Proxy Statement/Prospectus and the S-4 will comply as to form in all material respects with the applicable provisions of the Securities Act and the Exchange Act and the rules and regulations thereunder. Each of the Parties hereto agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by or on behalf of itself for inclusion or incorporation by reference in (i) the S-4 will, at the time the S-4 is filed with the SEC, at any time it is amended or supplemented or at the time it becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading or (ii) the Joint Proxy Statement/Prospectus will, at the date it is first mailed to shareholders of each of Investar and WFB (or such other Persons entitled to vote in respect of matters covered thereby) or at the time of the WFB Meeting and Investar Meeting, as applicable, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements, in light of the circumstances in which they were made, not misleading. If, at any time prior to the Effective Time, any information relating to the parties hereto, or any of their respective affiliates, will be discovered by WFB or Investar that, in the reasonable judgment of Investar, should be set forth in an amendment of, or a supplement to, any of the S-4 or the Joint Proxy Statement/Prospectus, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Party which discovers such information will promptly notify the other Party hereto, and the Party hereto will cooperate in the prompt filing with the SEC of any necessary amendment of, or supplement to, the Joint Proxy Statement/Prospectus or the S-4 and, to the extent required by Law, in disseminating the information contained in such amendment or supplement to shareholders of Investar and WFB. Investar will advise the WFB, promptly after Investar receives notice thereof, of the time when the S-4 has become effective, of the issuance of any stop order or the suspension of the qualification of Investar Common Stock issuable for offering or sale in any jurisdiction, or of any request by the SEC for the amendment or supplement of the S-4 or upon the receipt of any comments (whether written or oral) from the SEC or its staff. Investar will provide WFB and its counsel with a reasonable opportunity to review and comment on the S-4, and, except to the extent such response is submitted under confidential cover, all responses to requests for additional information by and replies to comments of the SEC prior to filing such with, or sending such to, the SEC. Investar will provide WFB and its counsel with a copy of all such filings made with the SEC.

(c) Investar will use its commercially reasonable efforts to cause the shares of Investar Common Stock to be issued in connection with the transactions contemplated by this Agreement to be approved for listing on Nasdaq, subject to official notice of issuance, prior to the Effective Time.

Section 6.06 Regulatory Filings; Consents.

(a) Each of Investar and WFB will, and will cause their respective Subsidiaries to, cooperate and use their respective reasonable best efforts (i) to promptly prepare all documentation, and to effect all applications, notices, and filings, to obtain all permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary to consummate the transactions contemplated by this Agreement (including the Regulatory Approvals) and required to consummate the Merger in the manner contemplated herein, (ii) to comply with the terms and conditions of such permits, consents, approvals and authorizations and (iii) to cause the transactions contemplated by this Agreement to be consummated as expeditiously as practicable; provided, however, notwithstanding the foregoing or anything to the contrary in this Agreement, nothing contained herein will be deemed to require Investar or any of its Subsidiaries or WFB or any of its Subsidiaries to agree to any increased minimum capital levels, or to take any other non-standard action, or commit to take any such action, or agree to any non-standard condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of any Governmental Authority that would reasonably be likely to have a material and adverse effect (measured on a scale relative to WFB) on the condition (financial or otherwise), results of operations, liquidity, assets or deposit liabilities, properties or business of Investar, WFB, the Surviving Company or the Surviving Bank, after giving effect to the Merger (“Burdensome Condition”). Investar and WFB will furnish each other and each other’s counsel with all information concerning themselves, their Subsidiaries, directors, trustees, officers and shareholders and such other matters as may be necessary or advisable in connection with any application, petition or any other statement or application made by or on behalf of Investar or WFB to any Governmental Authority in connection with the transactions contemplated by this Agreement. Each Party will have the right to review and approve in advance all characterizations of the information relating to such party and any of its Subsidiaries that appear in any public portions of such filing made in connection with the transactions contemplated by this Agreement with any Governmental Authority. In addition, Investar and WFB will each furnish to the other for review a copy of the public portions of each such filing made in connection with the transactions contemplated by this Agreement with any Governmental Authority prior to its filing.

(b) WFB will use its commercially reasonable efforts, and Investar will reasonably cooperate with WFB at WFB’s request, to obtain all consents, approvals, authorizations, waivers or similar affirmations described on WFB Disclosure Schedule Section 4.12(c) or that are otherwise required to be obtained under the terms of any WFB Material Contract in order to prevent the consummation of the transactions contemplated by this Agreement from constituting a default under such WFB Material Contract or creating any lien, claim, or charge upon any of the assets of WFB or any of its Subsidiaries. Each Party will notify the other Party promptly and will promptly furnish the other Party with copies of notices or other communications received by such Party or any of its Subsidiaries of any communication from any Person alleging that the consent of such Person (or another Person) is or may be required in connection with the transactions contemplated by this Agreement (and the response thereto from such Party, its Subsidiaries or its representatives). WFB will consult with Investar and its representatives as often as practicable under the circumstances so as to permit WFB and Investar and their respective representatives to cooperate to take appropriate measures to obtain such consents and avoid or mitigate any adverse consequences that may result from the foregoing.

Section 6.07 Publicity. Investar and WFB will consult with each other before issuing any press release with respect to this Agreement or the transactions contemplated hereby and will not issue any such press release or make any such public statement without the prior consent of the other Party, which will not be unreasonably delayed or withheld; provided, however, that (i) a party may, without the prior consent of the other party (but after such consultation, to the extent practicable in the circumstances), issue such press release or make such public statements as may upon the advice of counsel be required by Law or the rules and regulations of any stock exchanges and (ii) a Party may issue a press release or make a public statement (including, for avoidance of doubt, any filing with the SEC), that is consistent with prior press releases issued or public statements made in compliance with this Section without such consultation. It is understood that Investar will assume primary responsibility for the preparation of joint press releases relating to this Agreement, the Merger and the other transactions contemplated hereby.

Section 6.08 Access; Current Information.

(a) For the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, upon reasonable notice and subject to applicable Laws, WFB agrees to afford Investar and its officers, employees, counsel, accountants and other authorized representatives such access during normal business hours at any time and from time to time throughout the period prior to the Effective Time to WFB’s and its Subsidiaries’ books, records (including, without limitation, Tax Returns and work papers of independent auditors), information technology systems, business, properties and personnel and to such other information relating to them as Investar may reasonably request and WFB will use its commercially reasonable efforts to provide any appropriate notices to employees and/or customers in accordance with applicable Law and WFB’s privacy policy and, during such period, WFB will furnish to Investar, upon Investar’s reasonable request, all such other information concerning the business, properties and personnel of WFB and its Subsidiaries that is substantially similar in scope to the information provided to Investar in connection with its diligence review prior to the date of this Agreement.

(b) For the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, during the period of time from the date of this Agreement to the Effective Time, upon reasonable notice and subject to applicable Laws, Investar agrees to furnish to WFB such information as WFB may reasonably request concerning the business of Investar and its Subsidiaries that is substantially similar in scope to the information provided to WFB in connection with its diligence review prior to the date of this Agreement.

(c) As promptly as reasonably practicable after the end of the respective period, WFB will furnish to Investar unaudited monthly and quarterly financial statements for each month and fiscal quarter ended after the date of this Agreement.

(d) As promptly as reasonably practicable after they become available, WFB will furnish to Investar copies of the board packages distributed to the board of directors of WFB or any of its Subsidiaries, and minutes from the meetings thereof, copies of any internal management financial control reports showing actual financial performance against plan and previous period, and copies of any reports provided to the board of directors of WFB or any committee thereof relating to the financial performance and risk management of WFB.

(e) During the period from the date of this Agreement to the Effective Time, at the reasonable request of either Party, the other Party will cause one or more of its designated representatives to confer with representatives of the requesting Party and to report the general status of the ongoing operations of the other Party and its Subsidiaries. Without limiting the foregoing, WFB agrees to provide to Investar (i) to the extent permitted by applicable Law, a copy of each report filed by WFB or any of its Subsidiaries with a Governmental Authority, (ii) a copy of WFB’s monthly loan trial balance, and (iii) a copy of WFB’s monthly statement of condition and profit and loss statement and, if requested by Investar, a copy of WFB’s daily statement of condition and daily profit and loss statement, in each case, which will be provided as promptly as reasonably practicable after it is filed or prepared, as applicable. WFB further agrees to provide Investar, no later than ten (10) Business Days following the end of each calendar month following the date hereof, any supplements to WFB Disclosure Schedule Section 4.22(a) and WFB Disclosure Schedule Section 4.22(c) that would be required if the references to April 30, 2025 in each corresponding representation and warranty of WFB were changed to the date of the most recently ended calendar month.

(f) No investigation by a Party or its representatives will be deemed to modify or waive any representation, warranty, covenant or agreement of the other Party set forth in this Agreement, or the conditions to the respective obligations of Investar and WFB to consummate the transactions contemplated hereby.

(g) Notwithstanding anything to the contrary in this Section 6.08, WFB will not be required to copy Investar on any documents that disclose confidential discussions of this Agreement or the transactions contemplated hereby, that contain competitively sensitive business or other proprietary information filed under a claim of confidentiality (including any confidential supervisory information) or any other matter that WFB’s board of directors has been advised by counsel that such distribution to Investar may violate a confidentiality obligation or fiduciary duty or any Law or regulation, or may result in a waiver of WFB’s attorney-client privilege. In the event any of the restrictions in this Section 6.08(g) will apply, WFB will use its commercially reasonable efforts to provide appropriate consents, waivers, decrees and approvals necessary to satisfy any confidentiality issues relating to documents prepared or held by third parties (including work papers), the Parties will make appropriate alternate disclosure arrangements, including adopting additional specific procedures to protect the confidentiality of sensitive material and to ensure compliance with applicable Laws.

Section 6.09 No Solicitation by WFB; Superior Proposals.

(a) Except as permitted by Section 6.09(b), WFB will not, and will cause its Subsidiaries and each of their respective officers, directors and employees not to, and will not authorize any investment bankers, financial advisors, attorneys, accountants, consultants, affiliates or other agents of WFB or any of WFB’s Subsidiaries (collectively, the “WFB Representatives”) to, directly or indirectly, (i) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal; (ii) participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any Person (other than Investar) any information or data with respect to WFB or any of its Subsidiaries or otherwise relating to an Acquisition Proposal; (iii) release any Person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which WFB is a party; or (iv) enter into any agreement, confidentiality agreement, agreement in principle or letter of intent with respect to any Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal. Any violation of the foregoing restrictions by any of the WFB Representatives, whether or not such WFB Representative is so authorized and whether or not such WFB Representative is purporting to act on behalf of WFB or otherwise, will be deemed to be a breach of this Agreement by WFB. WFB and its Subsidiaries will, and will cause each of the WFB Representatives to, immediately cease and cause to be terminated any and all existing discussions, negotiations, and communications with any Persons with respect to any existing or potential Acquisition Proposal.

For purposes of this Agreement, “Acquisition Proposal” means any inquiry, offer or proposal (other than an inquiry, offer or proposal from Investar), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction.

For purposes of this Agreement, “Acquisition Transaction” means (i) any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving WFB or any of its Subsidiaries; (ii) any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, a significant portion of the assets of WFB or any of its Subsidiaries; (iii) any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing twenty percent (20%) or more of the votes attached to the outstanding securities of WFB or any of its Subsidiaries; (iv) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning twenty percent (20%) or more of any class of equity securities of WFB or any of its Subsidiaries; or (v) any transaction which is similar in form, substance or purpose to any of the foregoing transactions, or any combination of the foregoing.

For purposes of this Agreement, “Superior Proposal” means a bona fide, unsolicited Acquisition Proposal (i) that if consummated would result in a third party (or in the case of a direct merger between such third party and WFB or any of its Subsidiaries, the shareholders of such third party) acquiring, directly or indirectly, more than fifty percent (50%) of the outstanding WFB Common Stock or more than fifty percent (50%) of the assets of WFB and its Subsidiaries, taken as a whole, for consideration consisting of cash and/or securities and (ii) that the board of directors of WFB reasonably determines in good faith, after consultation with its outside financial advisor and outside legal counsel, (A) is reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal, including all conditions contained therein and the Person making such Acquisition Proposal, and (B) taking into account any changes to this Agreement proposed by Investar in response to such Acquisition Proposal, as contemplated by Section 6.09(e), and all financial, legal, regulatory and other aspects of such takeover proposal, including all conditions contained therein and the Person making such proposal, is more favorable to the shareholders of WFB from a financial point of view than the Merger.

(b) Notwithstanding Section 6.09(a) or any other provision of this Agreement, prior to the adoption of this Agreement by the Holders, WFB may take any of the actions described in Section 6.09(a)(ii) or (iv) if, but only if, (i) WFB has received a bona fide unsolicited written Acquisition Proposal that did not result from a breach of Section 6.09(a); (ii) the board of directors of WFB reasonably determines in good faith, after consultation with and having considered the advice of its outside financial advisor and outside legal counsel, that (A) such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (B) failure to take such actions would constitute a breach of its fiduciary duties to WFB’s shareholders under applicable Law; (iii) WFB has provided Investar with at least five (5) Business Days’ prior notice of such determination; and (iv) prior to furnishing or affording access to any information or data with respect to WFB or any of its Subsidiaries or otherwise relating to an Acquisition Proposal, WFB receives from such Person a confidentiality agreement with terms no less favorable to WFB than those contained in the confidentiality agreement with Investar. WFB will promptly provide to Investar any non-public information regarding WFB or its Subsidiaries provided to any other Person which was not previously provided to Investar, such additional information to be provided no later than the date of provision of such information to such other party.

(c) WFB will promptly (and in any event within twenty-four (24) hours) notify Investar in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, WFB or the WFB Representatives, in each case in connection with any Acquisition Proposal, and such notice will indicate the name of the Person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, providing copies of such materials (including e-mails or other electronic communications) except to the extent that such materials constitute confidential information of the Person making such offer or proposal under an effective confidentiality agreement). WFB agrees that it will keep Investar informed, on a reasonably current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications to such proposal, offer or request).

(d) Neither the board of directors of WFB nor any committee thereof will (i) withdraw, qualify, amend or modify, or propose to withdraw, qualify, amend or modify, in a manner adverse to Investar in connection with the transactions contemplated by this Agreement (including the Merger), the WFB Recommendation, fail to reaffirm the WFB Recommendation within three (3) Business Days following a request by Investar, or make any statement, filing or release, in connection with the WFB Meeting or otherwise, inconsistent with the WFB Recommendation (it being understood that taking a neutral position or no position with respect to an Acquisition Proposal will be considered an adverse modification of the WFB Recommendation); (ii) approve or recommend, or propose to approve or recommend, any Acquisition Proposal; or (iii) enter into (or cause WFB or any of its Subsidiaries to enter into) any letter of intent, agreement in principle, acquisition agreement or other agreement (A) related to any Acquisition Transaction (other than a confidentiality agreement entered into in accordance with the provisions of Section 6.09(b)) or (B) requiring WFB to abandon, terminate or fail to consummate the Merger or any other transaction contemplated by this Agreement.

(e) Notwithstanding Section 6.09(d), prior to the adoption of this Agreement by the Holders, the board of directors of WFB may withdraw, qualify, amend or modify the WFB Recommendation (a “WFB Subsequent Determination”) after the fifth (5^th) Business Day following Investar’s receipt of a notice (the “Notice of Superior Proposal”) from WFB advising Investar that the board of directors of WFB has decided that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of Section 6.09(a)) constitutes a Superior Proposal if, but only if, (i) the board of directors of WFB has determined in good faith, after consultation with and having considered the advice of outside legal counsel and its financial advisor, that the failure to take such actions would constitute a breach of its fiduciary duties to WFB’s shareholders under applicable Law, (ii) during the five (5) Business Day period after receipt of the Notice of Superior Proposal by Investar (the “Notice Period”), WFB and the board of directors of WFB will have cooperated and negotiated in good faith with Investar to make such adjustments, modifications or amendments to the terms and conditions of this Agreement as would enable WFB to proceed with the WFB Recommendation without a WFB Subsequent Determination; provided, however, that Investar will not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement and (iii) at the end of the Notice Period, after taking into account any such adjusted, modified or amended terms as may have been proposed by Investar since its receipt of such Notice of Superior Proposal, the board of directors of WFB has again in good faith made the determination (A) in clause (i) of this Section 6.09(e) and (B) that such Acquisition Proposal constitutes a Superior Proposal. In the event of any material revisions to the Superior Proposal, WFB will be required to deliver a new Notice of Superior Proposal to Investar and again comply with the requirements of this Section 6.09(e), except that the Notice Period will be reduced to three (3) Business Days and; provided, further, that WFB shall only be obligated to extend the notice contemplated by this Section 6.09(e) twice, and in the case of a Superior Proposal, Investar and the third party who has submitted the Superior Proposal shall each be required to submit its “best and final” offer or counter-offer, as applicable, by the end of the second Notice Period.

(f) Notwithstanding any WFB Subsequent Determination, and except if this Agreement is terminated by WFB pursuant to Section 8.01(g), this Agreement will be submitted to WFB’s shareholders at the WFB Meeting for the purpose of voting on the approval of this Agreement and the transactions contemplated hereby (including the Merger) and nothing contained herein will be deemed to relieve WFB of such obligation; provided, however, that if the board of directors of WFB will have made a WFB Subsequent Determination with respect to a Superior Proposal, then the board of directors of WFB may recommend approval of such Superior Proposal by the shareholders of WFB and may submit this Agreement to WFB’s shareholders without recommendation either for or against, in which event the board of directors of WFB will communicate the basis for its recommendation of such Superior Proposal and the basis for its lack of a recommendation with respect to this Agreement and the transactions contemplated hereby to WFB’s shareholders in the Joint Proxy Statement/Prospectus or an appropriate amendment or supplement thereto.

Section 6.10 Indemnification.

(a) For a period of six (6) years from and after the Effective Time, and in any event subject to the provisions of Section 6.10(c), Investar will indemnify and hold harmless the present and former directors and officers of WFB and its Subsidiaries (each an “Indemnified Party”), against all costs, expenses (including reasonable attorney’s fees), judgments, fines, losses, claims, damages or liabilities or amounts that are paid in settlement (which settlement will require the prior written consent of Investar, which consent will not be unreasonably withheld) of or in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (each a “Claim”), arising out of actions or omissions of such persons in the course of performing their duties for WFB or any of its Subsidiaries occurring at or before the Effective Time (including the Merger and the other transactions contemplated hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time, to the same extent permitted under the organizational documents of WFB and its Subsidiaries in effect on the date of this Agreement to the extent permitted by applicable Law; provided, however, that that notwithstanding anything to the contrary contained in the organizational documents of the WFB or its Subsidiaries, Investar will have no obligation to provide indemnification under this paragraph (a) to any Indemnified Party for any Excluded Claim; provided, further, that Investar’s obligation to indemnify any Indemnified Party under this Section 6.10 will be limited to the coverage provided under and the amounts actually covered by the D&O Insurance (as defined below).

(b) In connection with the indemnification provided pursuant to this Section 6.10, Investar and/or an Investar Subsidiary will advance expenses, promptly after statements therefor are received, to each WFB Indemnified Party, to the same extent permitted under the organizational documents of WFB and its Subsidiaries in effect on the date of this Agreement to the extent permitted by applicable Law (provided the individual to whom expenses are advanced provides an undertaking to repay such advance if it is ultimately determined that such individual is not entitled to indemnification), including the payment of the fees and expenses of one counsel with respect to a matter, and one local counsel in each applicable jurisdiction, if necessary or appropriate, selected by such WFB Indemnified Party or multiple Indemnified Parties, it being understood that they collectively will only be entitled to one counsel and one local counsel in each applicable jurisdiction where necessary or appropriate (unless a conflict will exist between them in which case they may retain separate counsel) and that all such counsel will be reasonably satisfactory to Investar. Investar will have no obligation to advance expenses related to any Excluded Claim.

(c) Any Indemnified Party wishing to claim indemnification under this Section 6.10 will promptly notify Investar upon learning of any Claim, provided that, failure to so notify will not affect the obligation of Investar under this Section 6.10, unless, and only to the extent that, Investar is materially prejudiced in the defense of such Claim as a consequence. In the event of any such Claim (whether asserted or claimed prior to, at or after the Effective Time), (i) Investar will have the right to assume the defense thereof and Investar will not be liable to such Indemnified Parties for any legal expenses or other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, (ii) the Indemnified Parties will cooperate in the defense of any such matter, (iii) Investar will not be liable for any settlement effected without its prior written consent, and (iv) Investar will have no obligation hereunder to any Indemnified Party if such indemnification would be in violation of any applicable federal or state banking Laws or regulations, or in the event that a federal or state banking agency or a court of competent jurisdiction will determine that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable Laws, whether or not related to banking Laws.

(d) WFB shall obtain, and before the Effective Time, WFB shall fully accrue or pay for, an extended reporting period policy under its current directors and officers liability insurance (“D&O Insurance”) with a claims period of six (6) years from and after the Effective Time, which insurance will contain at least the same coverage and amounts, and contain terms and conditions no less advantageous to the Indemnified Party, as that coverage currently provided by WFB; provided that, if WFB is unable to maintain or obtain the insurance called for by this Section 6.10, WFB will obtain as much comparable insurance as is reasonably available (subject to the limitations described below in this Section 6.10(d)). In no event will the premium amount for such D&O Insurance exceed of an amount equal to two hundred percent (200%) of the annual premiums paid by WFB for D&O Insurance in effect as of the date of this Agreement (the “Maximum D&O Tail Premium”). If the cost of such tail insurance exceeds the Maximum D&O Tail Premium, WFB will obtain tail insurance coverage or a separate tail insurance policy with the greatest coverage reasonably available for a cost not exceeding the Maximum D&O Tail Premium.

(e) This Section 6.10 will survive the Effective Time, is intended to benefit each WFB Indemnified Party (each of whom will be entitled to enforce this Section 6.10 against Investar), and will be binding on all successors and assigns of Investar.

(f) If Investar or any of its successors and assigns (i) will consolidate with or merge into any other corporation or entity and will not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) will transfer all or substantially all of its property and assets to any individual, corporation or other entity, then, in each such case, proper provision will be made so that the successors and assigns of Investar and its Subsidiaries will assume the obligations set forth in this Section 6.10.

Section 6.11 Employees; Benefit Plans.

(a) Following the Effective Time, Investar will maintain or cause to be maintained employee benefit plans for the benefit of employees who are full time employees of WFB on the Closing Date and who become employees of Investar in connection with the transaction contemplated hereunder (“Covered Employees”) that provide employee benefits which, in the aggregate, are substantially comparable to the employee benefits and cash-based compensation opportunities that are made available on a uniform and non-discriminatory basis to similarly situated employees of Investar; provided, however, that in no event will any Covered Employee be eligible to participate in any closed or frozen plan of Investar. Investar will give the Covered Employees credit for their prior service with WFB for purposes of eligibility (including initial participation and eligibility for current benefits) and vesting under any employee benefit plan maintained by Investar and in which Covered Employees may be eligible to participate to the extent permitted by such employee plan and applicable laws.

(b) With respect to any employee benefit plan of Investar that is a health, dental, vision or other welfare plan in which any Covered Employee is eligible to participate, for the plan year that includes the Closing, if Covered Employees are eligible to participate in such plans, Investar will use its commercially reasonable efforts to cause any pre-existing condition limitations, eligibility waiting periods or evidence of insurability requirements under such Investar plan to be waived with respect to such Covered Employee and his or her covered dependents to the extent such condition was or would have been covered under the comparable WFB Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time.

(c) Following the Effective Time, Investar Bank will credit each Covered Employee with an amount of paid time off equal to such Covered Employee’s accrued but unused paid time off at FNB (“Carryover PTO”); provided, however, that amount of each employee’s Carryover PTO shall not exceed the maximum amount permitted by Investar Bank’s policies and such Carryover PTO will be forfeited if not used in accordance with the terms of Investar Bank’s policies.

(d) Except for any employee (i) who is listed on WFB Disclosure Schedule Section 6.11(d); or (ii) any employee who receives a retention bonus pursuant to the pool established under Section 6.12 of this Agreement, any employee of WFB or FNB that becomes an employee of Investar or Investar Bank at the Effective Time who is terminated within six (6) months following the Effective Time (other than for cause, death, disability, normal retirement or voluntarily resignation) will receive a lump sum severance payment from Investar in an amount equal to two (2) week’s compensation at such Covered Employee’s base rate of compensation, multiplied by the number of whole years of service by such employee with WFB or FNB as of the Effective Time and Investar at the time of such termination, subject to a minimum of four (4) weeks’ base salary and a maximum of twenty-four (24) weeks’ base salary, and subject to the execution of a release of claims against Investar and its Affiliates in a form provided by Investar. For purposes of this paragraph, the term “cause” means any termination of employment due to the occurrence of one of more of the following events, as determined in the sole and absolute discretion of Investar: (i) the employee’s willful refusal to comply in any material respect with the lawful employment policies of Investar, (ii) the employee’s commission of an act of fraud, embezzlement or theft against Investar, (iii) the conviction or plea of nolo contendere to any crime involving moral turpitude or a felony, or (iv) the failure to substantially perform the duties and responsibilities of his or her position with Investar.

(e) [Reserved]

(f) Nothing in this Section 6.11 will be construed to limit the right of the Surviving Company to amend or terminate any WFB Benefit Plan or other employee benefit plan, to the extent such amendment or termination is permitted by the terms of the applicable plan, nor will anything in this Section 6.11 be construed to require Surviving Company to retain the employment of any particular Covered Employee for any fixed period of time following the Closing Date, and the continued retention (or termination) by Surviving Company of any Covered Employee subsequent to the Effective Time will be subject in all events to Investar’s normal and customary employment procedures and practices, including customary background screening and evaluation procedures, and satisfactory employment performance.

(g) For purposes of this Section 6.11, all references to WFB will include each of the Subsidiaries of WFB and all references to Investar will include each of the Subsidiaries of Investar.

(h) If requested by Investar in writing prior to the Closing Date, WFB will cause the 401(k) plan sponsored or maintained by WFB or FNB (each, a “WFB 401(k) Plan”) to be terminated effective as of the day immediately prior to the Closing Date and contingent upon the occurrence of the Closing. In the event that Investar requests that any WFB 401(k) Plan be terminated, (i) WFB will provide Investar with evidence that such plan has been terminated (the form and substance of which will be subject to reasonable review and comment by Investar) not later than two (2) days immediately preceding the Effective Time and (ii) Covered Employees will be eligible to participate, effective as of the Effective Time, in a 401(k) plan sponsored or maintained by Investar or one of its Subsidiaries (an “Investar 401(k) Plan”). Investar and WFB will take any and all actions as may be required, including amendments to any WFB 401(k) Plan and/or Investar 401(k) Plan, to permit Covered Employees to make rollover contributions to the Investar 401(k) Plan of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code) in an amount equal to the full account balance distributed to such Covered Employee from a WFB 401(k) Plan. If requested by Investar in writing prior to the Closing Date, WFB will also cause other WFB Benefit Plan to be terminated effective as of the day immediately prior to the Closing Date and contingent upon the occurrence of the Closing, and shall provide Investar with evidence that each such plan has been terminated (the form and substance of which will be subject to reasonable review and comment by Investar) not later than two (2) days immediately preceding the Effective Time.

Section 6.12 Retention Bonus Pool. Investar, in consultation with WFB, will establish a retention bonus pool, in the amount to be determined in the sole discretion of Investar but not more than $1,000,000, in order to encourage certain WFB and FNB employees to remain with Investar, thereby assisting Investar with continuity planning following the consummation of the transactions contemplated by this Agreement.

Section 6.13 Notification of Certain Changes. Investar and WFB will promptly advise the other Party of any change or event having, or which could reasonably be expected to have, a Material Adverse Effect or which it believes would, or which could reasonably be expected to, cause or constitute a material breach of any of its representations, warranties or covenants contained herein and WFB will provide on a periodic basis written notice to Investar of any matters that WFB becomes aware of that should be disclosed on a supplement or amendment to the WFB Disclosure Schedule.

Prior to the Effective Time, each of WFB and Investar will exercise, consistent with the terms and conditions of this Agreement, control and supervision over its and its Subsidiaries’ respective operations.

Section 6.17 Certain Litigation. Each Party will promptly advise the other Party orally and in writing of any actual or threatened shareholder litigation against such Party and/or the members of the board of directors of WFB or the board of directors of Investar related to this Agreement or the Merger and the other transactions contemplated by this Agreement. WFB will: (i) permit Investar to review and discuss in advance, and consider in good faith the views of Investar in connection with, any proposed written or oral response to such shareholder litigation; (ii) furnish Investar’s outside legal counsel with all non-privileged information and documents which outside counsel may reasonably request in connection with such shareholder litigation; (iii) consult with Investar regarding the defense or settlement of any such shareholder litigation, will give due consideration to Investar’s advice with respect to such shareholder litigation and will not settle any such litigation prior to such consultation and consideration; provided, however, that WFB will not settle any such shareholder litigation if such settlement requires the payment of money damages, without the written consent of Investar (such consent not to be unreasonably withheld, conditioned or delayed) unless the payment of any such damages by WFB is reasonably expected by WFB, following consultation with outside counsel, to be fully covered (disregarding any deductible to be paid by WFB) under WFB’s existing director and officer insurance policies, including any tail policy.

Section 6.18 Board Representation; Resignations. At or prior to the Effective Time, Investar will cause the number of directors that comprise the full board of directors of each of Investar and Investar Bank to be increased by two (2) and, effective as of the Effective Time, will appoint the two individuals who are current directors of WFB or FNB as of the date of this Agreement and designated on Investar Disclosure Schedule Section 6.18 (the “Board Representatives”) to serve as directors of the Surviving Company and the Surviving Bank in accordance with the bylaws of the Surviving Company or the Surviving Bank, as applicable, and shall nominate such Board Representatives and recommend such Board Representatives for re-election to the board of directors of each of Investar and Investar Bank at their next annual meeting of shareholders.

(a) Prior to the Effective Time, subject to applicable Laws, WFB and its Subsidiaries will take any actions Investar may reasonably request from time to time to better prepare the parties for integration of the operations of WFB and its Subsidiaries with Investar and its Subsidiaries, respectively. Without limiting the foregoing, senior officers of WFB and Investar will meet from time to time as Investar may reasonably request, and in any event not less frequently than monthly, to review the financial and operational affairs of WFB and its Subsidiaries, and WFB will give due consideration to Investar’s input on such matters, with the understanding that, notwithstanding any other provision contained in this Agreement, neither Investar nor Investar Bank will under any circumstance be permitted to exercise control of WFB or any of its Subsidiaries prior to the Effective Time. WFB will permit representatives of Investar Bank to be onsite at WFB to facilitate integration of operations and assist with any other coordination efforts as necessary, provided such efforts will be done without undue disruption to FNB’s business, during normal business hours and at the expense of Investar or Investar Bank (not to include FNB’s regular employee payroll).

(b) Prior to the Effective Time, subject to applicable Laws, WFB and its Subsidiaries will take any actions Investar may reasonably request in connection with negotiating any amendments, modifications or terminations of any Leases or WFB Material Contracts that Investar may request, including, but not limited to, actions necessary to cause any such amendments, modifications or terminations to become effective prior to (to the extent that the conditions set forth in Article VI of this Agreement have already been satisfied), or immediately upon, the Closing, and will cooperate with Investar and will use its commercially reasonable efforts to negotiate specific provisions that may be requested by Investar in connection with any such amendment, modification or termination.

(c) Prior to the Effective Time, subject to applicable Laws, WFB and its Subsidiaries will cooperate with Investar, upon its request, with respect to any plans by Investar to sell certain loans or other assets of WFB or its Subsidiaries contemporaneously with or immediately following the Closing, including, but not limited to, providing documentation or other information which may be requested by Investar in connection with its negotiation of any such sale or preparations by Investar to prepare for the consummation of such sale; provided however that nothing set forth herein this Section will be deemed to grant legal control to Investar over any such loans or other assets that Investar may desire to contemporaneously with or immediately following the Closing or obligate WFB or any of its Subsidiaries to enter into or consummate such a sale prior to or in the absence of the Closing.

(d) From and after the date hereof, subject to applicable Laws, the parties will reasonably cooperate (provided that the parties will cooperate to reasonably minimize disruption to WFB’s or FNB’s business) with the other in preparing for the prompt conversion or consolidation of systems and business operations promptly after the Effective Time (including by entering into customary confidentiality, non-disclosure and similar agreements with the other party and appropriate service providers) and WFB will, upon Investar’s reasonable request, introduce Investar and its representatives to suppliers of WFB and its Subsidiaries for the purpose of facilitating the integration of WFB and its business into that of Investar. In addition, after satisfaction of the conditions set forth in Section 7.01(a) and Section 7.01(b), subject to applicable Laws, WFB will, upon Investar’s reasonable request, introduce Investar and its representatives to customers of WFB and its Subsidiaries for the purpose of facilitating the integration of WFB and its business into that of Investar. Any interaction between Investar and WFB’s and any of its Subsidiaries’ customers and suppliers will be coordinated by WFB. WFB will have the right to participate in any discussions between Investar and WFB’s customers and suppliers.

(e) Investar and WFB agree to take all action necessary and appropriate to cause FNB to merge with Investar Bank in accordance with applicable Laws and the terms of the Bank Merger Agreement immediately following the Effective Time or as promptly as practicable thereafter.

Section 6.21 Confidentiality. Prior to the execution of this Agreement and prior to the consummation of the Merger, subject to applicable Laws, each of Investar and WFB, and their respective Subsidiaries, affiliates, officers, directors, agents, employees, consultants and advisors have provided, and will continue to provide one another with information which may be deemed by the party providing the information to be non-public, proprietary and/or confidential, including, but not limited to, trade secrets of the disclosing party. Each Party agrees that it will, and will cause its representatives to, hold any information obtained pursuant to this Agreement in accordance with the terms of that certain letter agreement regarding protection of Confidential Information (as defined therein), dated November 25, 2024, that has previously been entered into between the Parties.

Section 6.22 Section 16 Matters. Investar and WFB agree that, if the parties determine that any officer or director of WFB will be subject to the requirements of Section 16 of the Exchange Act (the “WFB Insiders”) immediately following the Effective Time, the respective boards of Investar and WFB, or in each case a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), will prior to the Effective Time take all such action as may be required to cause the transactions contemplated by this Agreement, including without limitation any dispositions of WFB Common Stock or WFB Equity Awards and any acquisitions of Investar Common Stock by any WFB Insiders, to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act to the fullest extent permitted by applicable Law.

Section 6.23 Code Section 280G Matters. If, after reviewing the Code Section 280G calculations and other supporting materials prepared by WFB and the WFB Representatives, either WFB or Investar determines that any Person who is a “disqualified individual” has a right to any payments and/or benefits as a result of or in connection with the execution of this Agreement and the consummation of the transactions contemplated hereby that would be deemed to constitute “parachute payments” (as such terms are defined in Section 280G of the Code and the Regulations promulgated thereunder) absent approval by the shareholders of WFB, then WFB will undertake its best efforts to modify its obligations to provide such payments or benefits to the extent necessary such that, after giving effect to such modifications, the modified payments or benefits would not constitute a parachute payment to a disqualified individual based on the Code Section 280G calculations. If, in the opinion of Investar, WFB is not able to modify its obligations to make such payments or benefits comply with the foregoing within thirty (30) days after determining that a payment or benefit would constitute a parachute payment to a disqualified individual, then at least three (3) Business Days prior to the Closing Date, WFB will take all necessary actions (including obtaining any required waivers or consents from each disqualified individual) to submit to a shareholder vote, in a manner that satisfies the shareholder approval requirements for exemption under Section 280G(b)(5)(A)(ii) of the Code and the regulations promulgated thereunder, the right of each disqualified individual to receive or retain, as applicable, any payments and benefits to the extent necessary so that no payment or benefit received by such disqualified person will be deemed a parachute payment. Such vote will establish the disqualified individual’s right to the payment or benefits. WFB will be responsible for all liabilities and obligations related to the matters described in this Section 6.23, including any claims by disqualified individuals that they are entitled to payment or reimbursement for any related excise taxes. WFB will provide to Investar copies of any waivers, consents, and shareholder information statements or disclosures relating to Code Section 280G and the shareholder vote described in this Section 6.23, a reasonable period of time before disseminating such materials to the disqualified individuals and WFB’s shareholders, and will work with Investar in good faith regarding the inclusion of any comments provided by Investar thereto. Prior to the Closing, WFB will deliver to Investar evidence that a vote of WFB’s shareholders who are entitled to vote was solicited in accordance with the foregoing provisions of this Section 6.23 and that the requisite number of shareholder votes was or was not obtained with respect thereto.

Section 6.24 Tax Matters.

(a) The Parties intend that each of the Merger and the Bank Merger will each qualify as a “reorganization” within the meaning of Section 368(a) of the Code and that this Agreement constitute a “plan of reorganization” within the meaning of Section 1.368-2(g) of the Regulations for each of the Merger and the Bank Merger. Except as expressly contemplated or permitted by this Agreement, from and after the date of this Agreement, each of Investar and WFB will use their respective reasonable best efforts to cause each of the Merger and the Bank Merger to qualify as a reorganization within the meaning of Section 368(a) of the Code, and will not take any action, cause any action to be taken, fail to take any action or cause any action to fail to be taken which action or failure to act is intended or is reasonably likely to prevent either the Merger or the Bank Merger from qualifying as a reorganization within the meaning of Section 368(a) of the Code.

(b) Investar will prepare or cause to be prepared and file or cause to be filed all Tax Returns for WFB and its Subsidiaries for all periods ending on or prior to the Closing Date that are filed after the Closing Date; provided, however, that WFB will cause its consolidated federal income Tax Return for the year ended December 31, 2024 to be filed prior to the Closing Date.

Section 6.25 Assumed Debt. The Parties agree to execute and deliver, or cause to be executed and delivered, at or prior to the Effective Time, one or more supplemental indentures and/or such other documents or instruments as may be required for the due and full assumption by Investar at the Effective Time of WFB’s obligations in respect of any outstanding debt, notes, guarantees, securities, or other instruments, including, without limitation, the trust preferred and subordinated debt securities set forth on Disclosure Schedule Section 4.02(c), to the extent required by the terms thereof. WFB agrees to cooperate as reasonably requested by Investar in connection with such assumption.

Section 6.26 Updated Disclosure Schedules. At least five (5) Business Days prior to the Closing, each Party will deliver to the other Party updated Schedules reflecting any material changes to the Schedules between the date of this Agreement and the Closing Date.

Section 6.27 Takeover Statutes. Neither Investar nor WFB, nor either of their respective boards of directors, will take any action that would cause any Takeover Statute to become applicable to this Agreement, the Merger or any of the other transactions contemplated hereby, and each will take all necessary steps to exempt (or ensure the continued exemption of) the Merger and the other transactions contemplated hereby from any applicable Takeover Statute now or hereafter in effect. If any Takeover Statute may become, or may purport to be, applicable to the transactions contemplated hereby, Investar, WFB and the members of their respective boards of directors will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Statute on any of the transactions contemplated by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Statute.

ARTICLE VIII

TERMINATION

Section 8.01 Termination. This Agreement may be terminated, and the transactions contemplated hereby may be abandoned, at any time prior to the Effective Time, whether before or after adoption of this Agreement by the shareholders of Investar or WFB:

(a) Mutual Consent. By the mutual consent, in writing, of Investar and WFB if the board of directors of Investar and the board of directors of WFB each so determines by vote of a majority of the members of its entire board.

(b) No Regulatory Approval. By Investar or WFB, if either of their respective boards of directors so determines by a vote of a majority of the members of its entire board, in the event that (i) any Regulatory Approval required for consummation of the transactions contemplated by this Agreement will have been denied by final, non-appealable action by such Governmental Authority, (ii) an application therefor will have been permanently withdrawn at the request of a Governmental Authority; (iii) Investar makes a reasonable determination in good faith after consultation with its counsel that there is a substantial likelihood that any Regulatory Approval will be obtained only upon the imposition of a Burdensome Condition; or (iv) any Governmental Authority will have issued a final nonappealable law or order permanently enjoining or otherwise prohibiting or making illegal the consummation of the Merger or the Bank Merger, provided however that the right to terminative under this Section will not be available to any Party whose failure to comply with any provision of this Agreement has been the cause of, or materially contributed to, such action.

(c) No Shareholder Approval. By either Investar or WFB (provided that such terminating Party will not be in breach of any of its obligations under Section 6.04), if the Requisite Investar Shareholder Approval or the Requisite WFB Shareholder Approval will not have been obtained by reason of the failure to obtain the required vote at a duly held meeting of such shareholders or at any adjournment or postponement thereof.

(d) Breach of Representations, Warranties, or Covenants. By either Investar or WFB (provided that the terminating Party is not then in material breach of any representation, warranty, covenant or other agreement contained herein in a manner that would entitle the other Party to not consummate this Agreement) if there will have been a breach of any of the covenants or agreements or any of the representations and warranties set forth in this Agreement on the part of the other Party, which breach, either individually or in the aggregate with all other breaches by such Party, would constitute, if occurring or continuing on the Closing Date, the failure of a condition set forth in Section 7.02(a), in the case of a termination by Investar, or Section 7.03(a), in the case of a termination by WFB, and which is not cured within thirty (30) days following written notice to Investar, in the case of a termination by WFB, or WFB, in the case of a termination by Investar, or which, by its nature, cannot be cured during such period (or such fewer days as remain prior to the Expiration Date).

(e) Delay. By either Investar or WFB, if the Merger will not have been consummated on or before March 31, 2026, or such later date as will have been agreed to in writing by Investar and WFB, provided, however, that such date will be automatically extended to June 30, 2026, if the only outstanding condition to Closing under Article VII is the receipt of all Regulatory Approvals (the “Expiration Date”), provided, further, that no Party may terminate this Agreement pursuant to this Section if the failure of the Closing to occur by such date was due to a material breach of this Agreement by the Party seeking to terminate this Agreement.

Section 10.07 Entire Understanding; No Third Party Beneficiaries. This Agreement represents the entire understanding of the Parties and thereto with reference to the transactions contemplated hereby, and this Agreement supersedes any and all other oral or written agreements heretofore made. Except for the Indemnified Parties’ rights under Section 6.10, Investar and WFB hereby agree that their respective representations, warranties and covenants set forth herein are solely for the benefit of the other Party, in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person (including any person or employees who might be affected by Section 6.11), other than the Parties, any rights or remedies hereunder, including, the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations between the Parties and are for the sole benefit of the Parties. Any inaccuracies in such representations and warranties are subject to waiver by the Parties hereto in accordance herewith without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the Parties hereto of risks associated with particular matters regardless of the Knowledge of any of the Parties hereto. Consequently, Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Section 10.08 Severability. In the event that any one or more provisions of this Agreement will for any reason be held invalid, illegal or unenforceable in any respect, by any court of competent jurisdiction, such invalidity, illegality or unenforceability will not affect any other provisions of this Agreement and the Parties will use their commercially reasonable efforts to substitute a valid, legal and enforceable provision which, insofar as practical, implements the purposes and intents of this Agreement.

Section 10.09 Enforcement of the Agreement. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties will be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction without having to show or prove economic damages and without the requirement of posting a bond, this being in addition to any other remedy to which they are entitled at law or in equity.

Section 10.10 Interpretation.

(a) When a reference is made in this Agreement to sections, exhibits or schedules, such reference will be to a section of, or exhibit or schedule to, this Agreement unless otherwise indicated. The table of contents and captions and headings contained in this Agreement are included solely for convenience of reference; if there is any conflict between a caption or heading and the text of this Agreement, the text will control. Whenever the words “include,” “includes” or “including” are used in this Agreement, they will be deemed to be followed by the words “without limitation.”

(b) The Parties have participated jointly in the negotiation and drafting of this Agreement and the other agreements and documents contemplated herein. In the event an ambiguity or question of intent or interpretation arises under any provision of this Agreement or any other agreement or document contemplated herein, this Agreement and such other agreements or documents will be construed as if drafted jointly by the Parties, and no presumption or burden of proof will arise favoring or disfavoring any party by virtue of authorizing any of the provisions of this Agreement or any other agreements or documents contemplated herein.

(c) The WFB Disclosure Schedule and the Investar Disclosure Schedule, as well as all other schedules and all exhibits to this Agreement, will be deemed part of this Agreement and included in any reference to this Agreement. Any matter disclosed pursuant to any section of either Disclosure Schedule will be deemed disclosed for purposes of any other section of Article IV or Article V, respectively, to the extent that applicability of the disclosure to such other section is reasonably apparent on the face, notwithstanding the absence of a specific cross-reference, of such disclosure. No item is required to be set forth in either Disclosure Schedule as an exception to a representation or warranty if its absence would not result in the related representation or warranty being deemed untrue or incorrect. The mere inclusion of an item in either Disclosure Schedule as an exception to a representation or warranty will not be deemed an admission by either Party that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a Material Adverse Effect, or that any breach or violation of applicable Laws or any contract exists or has actually occurred. This Agreement will not be interpreted or construed to require any person to take any action, or fail to take any action, if to do so would violate any applicable Law.

(d) Any reference contained in this Agreement to specific statutory or regulatory provisions or to any specific Governmental Authority will include any successor statute or regulation, or successor Governmental Authority, as the case may be. Unless the context clearly indicates otherwise, the masculine, feminine, and neuter genders will be deemed to be interchangeable, and the singular includes the plural and vice versa. As used herein, (i) the term “made available” means any document or other information that was (a) provided by one Party or its representatives to the other Party or its representatives prior to the date hereof, (b) included in the virtual data room of a Party prior to the date hereof, or (c) included in any registration statement, prospectus, report, schedule or definitive proxy statement filed with or furnished by Investar to the SEC and which is publicly available, and (ii) the word “or” is not exclusive.

(e) Unless otherwise specified, the references to “Section” and “Article” in this Agreement are to the Sections and Article of this Agreement. When used in this Agreement, words such as “herein”, “hereinafter”, “hereof”, “hereto”, and “hereunder” refer to this Agreement as a whole, unless the context clearly requires otherwise.

Section 10.11 Assignment. No Party may assign either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other Party, and any purported assignment in violation of this Section 10.11 will be void. Subject to the preceding sentence, this Agreement will be binding upon and will inure to the benefit of the Parties and their respective successors and permitted assigns.

Section 10.12 Counterparts. This Agreement may be executed and delivered by facsimile or by electronic data file and in one or more counterparts, all of which will be considered one and the same agreement and will become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Party, it being understood that all Parties need not sign the same counterpart.

Section 10.13 Delivery by Facsimile or Electronic Transmission. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by means of a facsimile machine or by e-mail delivery of a “.pdf” format data file, will be treated in all manner and respects as an original agreement or instrument and will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No Party hereto or to any such agreement or instrument will raise the use of a facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation of a contract and each Party hereto forever waives any such defense.
