WHEREAS, the Company is willing to acquire all of the outstanding shares of the Bank pursuant to the terms and subject to the conditions set forth in this Exchange Plan;

NOW, THEREFORE, in consideration of the mutual covenants, agreements, and provisions contained herein and other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and subject to the satisfaction of the terms and conditions set forth herein, intending to be legally bound hereby, the parties agree as follows:

1.1 Exchange. Subject to the terms and conditions contained in this Exchange Plan, the Company and the Bank will execute and file articles of share exchange (the “Articles of Share Exchange”), pursuant to which the Company will acquire all of the issued and outstanding shares of $1.00 par value common stock of the Bank (“Bank Common Stock”) in exchange for shares of its $1.00 par value Common Stock (“Company Common Stock”) and pursuant to which the Company will acquire all of the issued and outstanding warrants of the Bank (“Bank Warrants”) in exchange for its warrants (“Company Warrants”), hereinafter sometimes referred to as the “Exchange”.

1.2 The Closing. The “Closing” of the Exchange will take place at the main banking office of Investar Bank in Baton Rouge, Louisiana, at 10:00 a.m., Central Standard Time, on a mutually agreeable date as soon as practicable following satisfaction of the conditions in Section 6 hereof. The date on which the Closing occurs is herein called the “Closing Date.” If all conditions in Section 6 hereof are satisfied, at the Closing (i) the Company, on the one hand, and the Bank, on the other hand, shall each provide to the other such proof of satisfaction of the conditions in Section 6 as the party whose obligations are conditioned upon such satisfaction may reasonably request, (ii) the appropriate parties and/or officers of the parties shall execute, deliver, and acknowledge the Articles of Share Exchange, and (iii) the parties shall take such further action as is required to consummate the share exchange transaction contemplated by this Exchange Plan and the Articles of Share Exchange.

1.3 The Effective Date and Time. As soon as practicable following the Closing, the Articles of Share Exchange shall be filed with the Louisiana Secretary of State as provided by law and the Exchange will be effective at the time specified in a certificate or other written record issued by the Secretary of State. The date on which and the time at which the Exchange becomes effective are herein referred to as the “Effective Date” and the “Effective Time,” respectively.

1.4 Effect of Exchange. At the Effective Time, all of the issued and outstanding shares of the Bank Common Stock will be exchanged for shares of Company Common Stock at the ratio of one-for-one (1:1) and all of the issued and outstanding Bank Warrants will be exchanged for Company Warrants at the ratio of one-for-one (1:1) and thereupon cancelled.

1.5 Method of Effecting Exchange. This Exchange Plan shall be submitted to the shareholders of the Bank for their approval. If such approval is given, then the fact of such approval shall be certified on the Articles of Share Exchange by the respective Secretaries of the Company and the Bank, and the Articles of Share Exchange, so approved and certified, shall, as soon as is practical, be executed and acknowledged by the Presidents or Vice-Presidents of both the Company and the Bank. As soon as may be practicable thereafter, an original, so certified, signed and acknowledged, shall be delivered to the Louisiana Secretary of State for filing in the manner required by law.

2.1 Conversion of Shares. Except for shares as to which dissenters’ rights have been perfected and not withdrawn or otherwise forfeited under Section 376 of the Louisiana Banking Law (the “LBL”), on the Effective Date, by reason of the Exchange, every one (1) share of the issued and outstanding shares of Bank Common Stock shall be converted into the right to receive one (1) whole share of Company Common Stock.

2.2 Certificates for Shares. After the Effective Time, each holder of an outstanding certificate or certificates theretofore representing shares of Bank Common Stock, (other than shares as to which dissenters’ rights have been perfected and not withdrawn or otherwise forfeited under Section 376 of the LBL), upon surrender thereof to the Company, shall be entitled to receive a certificate or certificates representing the whole number of shares of Company Common Stock into which such shares have been exchanged as provided in Subsection 2.1. Until so surrendered, each outstanding certificate shall be deemed for all purposes to represent the right to receive the number of shares of Company Common Stock into which the shares represented by such certificate shall have been exchanged pursuant to Subsection 2.1, but the holder of such certificate shall have no other rights with respect thereto. Notwithstanding anything herein to the contrary, neither the Company nor the Bank will be liable to any former holder of Bank Common Stock with respect to any amount delivered in good faith to a public official pursuant to any applicable abandoned property, escheat or similar laws. In the event that any certificate representing shares of Bank Common Stock 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 required by the Company, the posting by such person of a bond in such amount as the Company may determine is necessary as indemnity against any claim that may be made against it with respect to such certificate, the Company will deliver in exchange for the lost, stolen or destroyed certificate the consideration due to such person pursuant to this Agreement.

2.3 Fractional Shares. No fractional shares of any class or series of Company Stock will be issued as a consequence of this Exchange. In lieu of fractional shares, holders of shares of Bank Common Stock that would otherwise be entitled to a fractional share interest shall be paid an amount in cash equal to the product of (i) the Fair Value (as defined below) per share of Bank Common Stock multiplied by (ii) the fraction of a share of Company Common Stock that would otherwise have been issued. For purposes of this Agreement, “Fair Value” per share means the appraised value of the Bank Common Stock as determined by the most recent (not older than 12 months) appraisal by an independent, qualified investment banking firm or financial consultant satisfactory to the Board of Directors of the Bank in its sole discretion, using such methodologies as the appraiser deems reasonable.

3.1 Conversion of Warrants. On the Effective Date, by reason of the Exchange, each of the issued and outstanding Bank Warrants shall be converted into the right to receive one (1) whole warrant of Company Warrants and all of the issued and outstanding Bank Warrants shall thereupon be cancelled.

3.2 Certificates for Warrants. After the Effective Time, each holder of an outstanding certificate or certificates theretofore representing Bank Warrants, upon surrender thereof to the Company, shall be entitled to receive a certificate or certificates representing the whole number of Company Warrants into which such Bank Warrants have been exchanged as provided in Subsection 3.1. Until so surrendered, each outstanding certificate shall be deemed for all purposes to represent the right to receive the number of Company Warrants into which the warrants represented by such certificate shall have been exchanged pursuant to Subsection 3.1, but the holder of such certificate shall have no other rights with respect thereto.
