Item 1.01 Entry into a Material Definitive Agreement

Agreement and Plan of Merger

Merger. On November 6, 2018, The First Bancshares, Inc., a Mississippi corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with FPB Financial Corp., a Louisiana corporation (“FPB”), whereby FPB will be merged with and into the Company (the “Merger”). Pursuant to and simultaneously with entering into the Merger Agreement, the Company’s wholly owned subsidiary bank, The First, A National Banking Association (“The First”), and FPB’s wholly owned subsidiary bank, Florida Parishes Bank, entered into a Plan of Merger and Merger Agreement whereby Florida Parishes Bank will be merged with and into The First immediately following the merger of FPB with and into the Company (the “Bank Merger”).

The Merger Agreement has been unanimously approved by the boards of directors of the Company and FPB. The transaction is expected to close in the first quarter of 2019, subject to customary conditions discussed below.

Merger Consideration. Pursuant to the Merger Agreement, each outstanding share of FPB stock issued and outstanding immediately prior to the effective time of the Merger will be converted into the right to receive 0.83 (the “Exchange Ratio”) shares of the Company’s common stock, provided that the Exchange Ratio is subject to adjustment in accordance with the terms of the Merger Agreement in the event that the average closing price of a share of the Company’s Common Stock on the NASDAQ Global Select Market over the ten (10) trading days ending five (5) Business Days immediately prior to the Closing Date (the “Measurement Price”) is either less than $34.61 or greater than $43.39. FPB will use its best efforts to amend the terms of the outstanding in-the-money warrants to purchase shares of FPB common stock such that the warrants will be converted into the right to receive an amount of cash, without interest, equal to the product of (i) the total number of shares of FPB common stock subject to such warrant times (ii) the excess, if any, of (A) the product of the Measurement Price multiplied by the Exchange Ratio, over (B) the exercise price per share of FPB common stock under such warrant, less applicable Taxes required to be withheld with respect to such payment. Any warrants to purchase FPB common stock that are not effectively amended or exercised will be assumed by FBMS, subject to adjustment in accordance with the terms of the Merger Agreement.

Each outstanding share of the Company’s common stock shall remain outstanding and unaffected by the Merger.

Representations and Warranties. The Merger Agreement contains usual and customary representations and warranties that the Company and FPB made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the contract between the Company and FPB and may be subject to important qualifications and limitations agreed to by the parties in connection with negotiating certain terms. Moreover, certain of the representations and warranties are subject to a contractual standard of materiality that may be different from what may be viewed as material to shareholders, and the representations and warranties may have been used to allocate risk between the Company and FPB rather than establishing matters of fact.

Covenants; No Solicitation. Each party also has agreed to customary covenants, including, among others, covenants relating to the conduct of its business during the interim period between the execution of the Merger Agreement and the consummation of the Merger. Additionally, FPB has agreed (i) not to initiate, solicit, induce or knowingly encourage or take any action or facilitate any alternative acquisition transaction or, subject to certain exceptions, participate in discussions or negotiations regarding, or furnish any non-public information relating to, any alternative acquisition transaction or (ii) subject to certain exceptions, not to withdraw or modify in a manner adverse to the Company, the recommendation of the FPB board of directors that FPB’s shareholders approve the Merger Agreement and the Merger. In the event that FPB receives a proposal with respect to an alternative acquisition transaction that the FPB board of directors determines is superior to the Merger, the Company will have an opportunity to match the terms of such proposal, subject to certain requirements.

Conditions to Closing. Consummation of the Merger is subject to various customary conditions, including (i) approval of the Merger Agreement and the Merger by shareholders of FPB; (ii) the receipt of certain regulatory approvals; (iii) no injunctions or other legal restraints preventing the consummation of the Merger; (iv) the U.S. Securities and Exchange Commission (“SEC”) having declared effective the Company’s registration statement covering the issuance of shares of the Company’s common stock in the Merger; (v) the receipt by each party of a tax opinion to the effect that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended; (vi) the accuracy of representations and warranties of the parties and compliance by the parties with their respective covenants and obligations under the Merger Agreement (subject to customary materiality qualifiers); and (vii) the absence of a material adverse effect with respect to the either the Company or FPB.

Termination. The Merger Agreement may be terminated in certain circumstances, including: (i) by mutual written agreement of the parties, (ii) by either party if any regulatory approval required for consummation of the transactions contemplated by the Merger Agreement has been denied by final non-appealable action by the relevant governmental authority or an application for such approval has been permanently withdrawn at the request of a governmental authority, (iii) by either party if the approval of the shareholders of FPB is not obtained, (iv) by either party in the event of a material breach by the other party of any representation, warranty or covenant contained in the Merger Agreement and such breach is not cured within thirty days, (v) by either party if the Merger is not consummated on or before June 30, 2019, subject to automatic extension to September 30, 2019 if the only outstanding closing condition is the receipt of regulatory approvals, (vi) by the Company if FPB’s board of directors breaches its obligation not to solicit any alternative acquisition transaction, changes its recommendation with respect to the Merger in accordance with the terms of the Merger Agreement, or breaches its obligation to call a special FPB shareholder meeting to vote on the Merger, (vii) by the Company or FPB in the event that the average closing price of a share of the Company’s Common Stock on the NASDAQ Global Select Market over the ten (10) trading days ending five (5) Business Days immediately prior to the Closing Date is either less than $33.15 or greater than $44.85, or (viii) by FPB in order to enter into an agreement to a superior proposal.

Termination Fee. FPB will pay the Company a termination fee equal to $3.6 million in the event (i) the Merger Agreement is terminated by the Company because FPB’s board of directors breaches its obligation not to solicit any alternative acquisition transaction, changes its recommendation with respect to the Merger in accordance with the terms of the Merger Agreement, or breaches its obligation to call a special FPB shareholder meeting to vote on the Merger, (ii) FPB terminates this agreement in order to accept a superior proposal, or (iii) the Merger Agreement is terminated (A) by either the Company or FPB because the required FPB shareholder approval is not obtained or (B) the Merger Agreement is terminated by the Company because of FPB’s material breach of representations, warranties or covenants, FPB receives an acquisition proposal after the date of the Merger Agreement but before it is terminated, and FPB enters into an agreement for or completes an acquisition transaction within 12 months of the termination of the Merger Agreement.

The foregoing summary of the Merger Agreement is not complete and is qualified in its entirety by reference to the full text of the Merger Agreement and certain exhibits attached thereto, a copy of which is attached hereto as Exhibit 2.1 and incorporated by reference herein.  The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the Company, its affiliates and their respective businesses, and the information regarding the Merger Agreement and the Merger that will be contained in, or incorporated by reference into, the registration statement on Form S-4 of the Company that will include a proxy statement of FPB and a prospectus of the Company and that will be filed with the Securities and Exchange Commission (the “SEC”).

Voting Agreements

In connection with entering into the Merger Agreement, the directors of FPB have entered into voting agreements (the “Voting Agreements”), pursuant to which each such director agreed to vote his, her or its shares of FPB common stock in favor of approval of the Merger Agreement and transactions contemplated therein and against certain other actions, proposals, transactions or agreements that would be detrimental to the consummation of the Merger. The Voting Agreements generally prohibit the sale or transfer of the shares held by each such shareholder until the earlier of (i) termination of the Merger Agreement and (ii) receipt of the approval of the shareholders of FPB. The Voting Agreements terminate upon the earlier of (i) the consummation of the Merger, (ii) the amendment of the Merger Agreement in any manner that materially and adversely affects any rights of the shareholder, (iii) the termination of the Merger Agreement or (iv) two years from the date of the Voting Agreements.

The foregoing summary of the Voting Agreements is qualified in its entirety by reference to the complete text of such documents, forms of which are included as Exhibit A to the Merger Agreement, filed as Exhibit 2.1 attached hereto and which is incorporated herein by reference.

Director Non-Compete Agreements

In connection with entering into the Merger Agreement, each of the directors of FPB and Florida Parishes Bank entered into a Non-Competition and Non-Disclosure Agreement with the Company, which contains provisions related to the non-disclosure of confidential information and trade secrets, non-solicitation of customers with whom such directors had material contact, non-competition within a restricted territory and non-recruitment of employees.

The foregoing summary of the Non-Competition and Non-Disclosure Agreement is qualified in its entirety by reference to the complete text of such document, a form of which is included as Exhibit C to the Merger Agreement, filed as Exhibit 2.1 attached hereto and which is incorporated herein by reference.

Cautionary Statements Regarding Forward-Looking Information.

This Current Report contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. In general, forward-looking statements usually use words such as “may,” “believe,” “expect,” “anticipate,” “intend,” “will,” “should,” “plan,” “estimate,” “predict,” “continue” and “potential” or the negative of these terms or other comparable terminology, including statements related to the expected timing of the closing of the Merger, the expected returns and other benefits of the Merger, to shareholders, expected improvement in operating efficiency resulting from the Merger, estimated expense reductions resulting from the transactions and the timing of achievement of such reductions, the impact on and timing of the recovery of the impact on tangible book value, and the effect of the Merger on the Company’s capital ratios. Forward-looking statements represent management’s beliefs, based upon information available at the time the statements are made, with regard to the matters addressed; they are not guarantees of future performance. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements.

Factors that could cause or contribute to such differences include, but are not limited to (1) the risk that the cost savings and any revenue synergies from the Merger may not be realized or take longer than anticipated to be realized, (2) disruption from the Merger with customers, suppliers, employee or other business partners relationships, (3) the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, (4) the risk of successful integration of FPB’s business into the Company, (5) the failure to obtain the necessary approval by the shareholders of FPB, (6) the amount of the costs, fees, expenses and charges related to the Merger, (7) the ability by the Company to obtain required governmental approvals of the Merger, (8) reputational risk and the reaction of each of the companies’ customers, suppliers, employees or other business partners to the Merger, (9) the failure of the closing conditions in the Merger Agreement to be satisfied, or any unexpected delay in closing of the Merger, (10) the risk that the integration of FPB’s operations into the operations of the Company will be materially delayed or will be more costly or difficult than expected, (11) the possibility that the Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (12) the dilution caused by the Company’s issuance of additional shares of its common stock in the Merger transaction, and (13) general competitive, economic, political and market conditions. Additional factors which could affect the forward looking statements can be found in the cautionary language included under the headings “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 and other documents subsequently filed by the Company with the SEC. Consequently, no forward-looking statement can be guaranteed. Neither the Company nor FPB undertakes any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For any forward-looking statements made in this Current Report on Form 8-K, the exhibits hereto or any related documents, the Company and FPB claim protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

WHEREAS, the boards of directors of the Parties have determined that it is in the best interests of their respective companies and their respective shareholders to consummate the business combination transaction provided for in this Agreement in which FPB will, on the terms and subject to the conditions set forth in this Agreement, merge with and into FBMS (the “Merger”), with FBMS as the surviving company in the Merger (sometimes referred to in such capacity as the “Surviving Entity”);

WHEREAS, as a condition to the willingness of FBMS to enter into this Agreement, certain directors of FPB have entered into voting agreements (each a “FPB Voting Agreement” and collectively, the “FPB Voting Agreements”), substantially in the form attached hereto as Exhibit A, dated as of the date hereof, with FBMS, pursuant to which each such director has agreed, among other things, to vote certain of the FPB Common Stock owned by such director in favor of the approval of this Agreement and the transactions contemplated hereby, subject to the terms of the FPB Voting Agreements;

WHEREAS, the Parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger; and

WHEREAS, for federal income tax purposes, it is intended that the Merger qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and the Treasury Regulations promulgated thereunder (the “Code”), and this Agreement is intended to be and is adopted as a “plan of reorganization” for purposes of Sections 354 and 361 of the Code.

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:

Article I

THE MERGER

Section 1.01The Merger.

In the event that FBMS elects to make such a change, the Parties agree to cooperate to execute appropriate documents to reflect the change.

Article II

MERGER CONSIDERATION; EXCHANGE PROCEDURES

Section 2.01Merger 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 FPB:

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

(b)Each share of FPB Common Stock owned directly by FBMS, FPB or any of their respective Subsidiaries (other than 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 shall be cancelled and retired at the Effective Time without any conversion thereof, and no payment shall be made with respect thereto (the “FPB Cancelled Shares”).

(c)Notwithstanding anything in this Agreement to the contrary, all shares of FPB Common Stock that are issued and outstanding immediately prior to the Effective Time and which

3

are held by a shareholder who did not vote in favor of the Merger (or consent thereto in writing) and who is entitled to demand and properly demands the fair value of such shares pursuant to, and who complies in all respects with, the provisions of Title 12, Part 13 of the LBCA, shall not be converted into or be exchangeable for the right to receive the Merger Consideration (the “Dissenting Shares”), but instead the holder of such Dissenting Shares (hereinafter called a “Dissenting Shareholder”) shall be entitled to payment of the fair value of such shares in accordance with the applicable provisions of the LBCA (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist and such holder shall cease to have any rights with respect thereto, except the rights provided for pursuant to the applicable provisions of the LBCA and this Section 2.01(c)), unless and until such Dissenting Shareholder shall have failed to perfect such holder’s right to receive, or shall have effectively withdrawn or lost rights to demand or receive, the fair value of such shares of FPB Common Stock under the applicable provisions of the LBCA. If any Dissenting Shareholder shall fail to perfect or effectively withdraw or lose such Holder’s dissenter’s rights under the applicable provisions of the LBCA, each such Dissenting Share shall be deemed to have been converted into and to have become exchangeable for the right to receive the Merger Consideration, without any interest thereon, in accordance with the applicable provisions of this Agreement. FPB shall give FBMS (i) prompt notice of any written notices to exercise dissenters’ rights in respect of any shares of FPB Common Stock, attempted withdrawals of such notices and any other instruments served pursuant to the LBCA and received by FPB relating to dissenters’ rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under the LBCA. FPB shall not, except with the prior written consent of FBMS, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment. Any portion of the Merger Consideration made available to the Exchange Agent pursuant to this Article II to pay for shares of FPB Common Stock for which dissenters’ rights have been perfected shall be returned to FBMS upon demand. If the amount paid to a Dissenting Shareholder exceeds such Dissenting Shareholder’s Merger Consideration, such excess amount shall not reduce the amount of Merger Consideration paid to other Holders.

(d)Each share of FPB Stock (excluding Dissenting Shares and FPB Cancelled Shares) issued and outstanding at the Effective Time shall cease to be outstanding and shall be converted, in accordance with the terms of this Article II, into and exchanged for the right to receive 0.83 (the “Exchange Ratio”) of a share of FBMS Common Stock (the “Merger Consideration”). The Exchange Ratio is subject to adjustment as set forth below: (i) if the Measurement Price (as defined below) is greater than $43.39 per share, then the Exchange Ratio shall be adjusted to equal the quotient (rounded to the nearest ten thousandth of a share) obtained by dividing $36.01 by the Measurement Price; and (ii) if the Measurement Price is less than $34.61 per share, then the Exchange Ratio shall be adjusted to equal the quotient (rounded to the nearest ten thousandth of a share) obtained by dividing $28.73 by the Measurement Price, subject in each case to the Parties’ respective rights to terminate the Agreement pursuant to Section 7.01(i). As used in this Agreement, the term “Measurement Price” means the average closing price of a share of FBMS Common Stock on the NASDAQ Global Select Market over the ten (10) trading days ending five (5) Business Days immediately prior to the Closing Date.

(e)If, between the date hereof and the Effective Time, the outstanding shares of FPB Common Stock or FBMS Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization,

4

stock dividend, stock split, reverse stock split or similar change in capitalization, appropriate and proportionate adjustments shall be made to the Merger Consideration.

Section 2.02FPB Stock-Based Awards.

(a)Immediately prior to the Effective Time, each share of FPB Common Stock subject to vesting restrictions granted under the FPB Stock Plans (a “FPB Restricted Share”) that is outstanding immediately prior to the Effective Time shall become fully vested and nonforfeitable and shall be converted automatically into and shall thereafter represent the right to receive the Merger Consideration, less the amount of any required withholding Tax, pursuant to Section 2.01(d).

(b)Between the date of this Agreement and the Closing Date, FPB shall seek and use its best efforts to obtain from each holder of warrants to purchase FPB Common Stock (each a “FPB Warrant”) a written consent to the termination and cash-out of the holder’s outstanding FPB Warrants in connection with the Merger, as provided in Section 2.02(c). FPB Warrants for which such consent is obtained are referred to herein as the “Consented FPB Warrants,” and FPB Warrants for which such consent is not obtained are referred to herein as the “Unconsented FPB Warrants.”

(c)At the Effective Time, each Consented FPB Warrant that is outstanding immediately prior to the Effective Time shall be cancelled and the holder thereof shall be entitled to receive from FPB immediately prior to the Effective Time an amount in cash, without interest, equal to the product of (i) the total number of shares of FPB Common Stock subject to such Consented FPB Warrant times (ii) the excess, if any, of (A) the product of the Measurement Price multiplied by the Exchange Ratio (the “Cash-Out Price”), over (B) the exercise price per share of FPB Common Stock under such Consented FPB Warrant, less applicable Taxes required to be withheld with respect to such payment. No holder of a Consented FPB Warrant that has an exercise price per share of FPB Common Stock that is equal to or greater than Cash-Out Price shall be entitled to any payment with respect to such Consented FPB Warrant before, on or after the Effective Time.

(d)At the Effective Time, each Unconsented FPB Warrant that is outstanding immediately prior to the Effective Time shall be converted into and shall become a warrant to purchase shares of FBMS Common stock, and FBMS shall assume each Unconsented FPB Warrant (as so assumed, an “Assumed Warrant”) in accordance with the terms and conditions of the warrant certificate by which it is evidenced, except that (i) each Assumed Warrant may be exercised solely for shares of FBMS Common Stock, (ii) the number of shares of FBMS Common Stock subject to such Assumed Warrant shall be equal to the number of shares of FPB Common Stock subject to the Unconsented FPB Warrant immediately prior to the Effective Time multiplied by the Exchange Ratio and rounding down to the nearest share, and (iii) the per share exercise price of such Assumed Warrant shall be adjusted by dividing the per share exercise price of the Unconsented FPB Warrant immediately prior to the Effective Time by the Exchange Ratio and rounding down the nearest cent. The holder of any Assumed Warrant shall receive cash in lieu of fractional shares of FBMS Common Stock in accordance with this Article II.

5

(e)Prior to the Effective Time, the board of directors of FPB (or, if appropriate, any committee thereof administering the FPB Stock Plans) shall adopt such resolutions or take such other actions, including obtaining any necessary amendments to the applicable award agreements, warrant agreements and equity plans, as may be required to effectuate the provisions of this Section 2.02.

Section 2.03Rights as Shareholders; Stock Transfers. At the Effective Time, all shares of FPB Common Stock, when converted in accordance with Section 2.01, shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each Certificate or Book-Entry Share previously evidencing such shares shall thereafter represent only the right to receive for each such share of FPB Common Stock, the Merger Consideration and any cash in lieu of fractional shares of FBMS Common Stock in accordance with this Article II. At the Effective Time, holders of FPB Common Stock shall cease to be, and shall have no rights as, shareholders of FPB, other than the right to receive the Merger Consideration and cash in lieu of fractional shares of FBMS Common Stock as provided under this Article II. At the Effective Time, the stock transfer books of FPB shall be closed, and there shall be no registration of transfers on the stock transfer books of FPB of shares of FPB Common Stock.

Section 2.04Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of FBMS Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger. In lieu thereof, FBMS shall pay or cause to be paid to each Holder of a fractional share of FBMS Common Stock or holder of an Assumed Warrant that, as adjusted pursuant to Section 2.02(d), would have resulted in a warrant to purchase a fractional share of FBMS Common Stock, rounded to the nearest one hundredth of a share, an amount of cash (without interest and rounded to the nearest whole cent) determined by multiplying the fractional share interest in FBMS Common Stock to which such Holder or Assumed Warrant holder would otherwise be entitled by the FBMS Closing Price.

Section 2.05Plan of Reorganization. It is intended that the Merger and the Bank Merger shall each qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement shall constitute a “plan of reorganization” as that term is used in Sections 354 and 361 of the Code.

Section 2.06Exchange Procedures. FBMS shall cause as promptly as practicable after the Effective Time, but in no event later than three (3) Business Days after the Closing Date, the Exchange Agent to mail or otherwise caused to be delivered to each Holder who has not previously surrendered such Certificate or Certificates or Book Entry Shares, appropriate and customary transmittal materials, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares shall 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 Merger Consideration (including cash in lieu of fractional shares) as provided for in this Agreement (the “Letter of Transmittal”). The Letter of Transmittal shall be subject to the approval of FPB, which approval shall not be unreasonably withheld, conditioned or delayed.

Section 2.07Deposit and Delivery of Merger Consideration.

6

(a)Prior to the Effective Time, FBMS shall (i) deposit, or shall cause to be deposited, with the Exchange Agent stock certificates representing the number of shares of FBMS Common Stock and cash sufficient to deliver the Merger Consideration (together with, to the extent then determinable, any cash payable in lieu of fractional shares pursuant to Section 2.04, and if applicable, cash in an aggregate amount sufficient to make the appropriate payment to the Holders of Dissenting Shares and the holders of Consented FPB Warrants) (collectively, the “Exchange Fund”), and (ii) instruct the Exchange Agent to pay such Merger Consideration and cash in lieu of fractional shares in accordance with this Agreement as promptly as practicable after the Effective Time and conditioned upon receipt of a properly completed Letter of Transmittal. The Exchange Agent and FBMS, as the case may be, shall not be obligated to deliver the Merger Consideration to a Holder to which such Holder would otherwise be entitled as a result of the Merger until such Holder surrenders the Certificates or Book-Entry Shares representing the shares of FPB Common Stock for exchange as provided in this Article II, or an appropriate affidavit of loss and indemnity agreement and/or a bond in such amount as may be reasonably required in each case by FBMS or the Exchange Agent.

(b)Any portion of the Exchange Fund that remains unclaimed by the shareholders of FPB for one (1) year after the Effective Time (as well as any interest or proceeds from any investment thereof) shall be delivered by the Exchange Agent to FBMS. Any shareholders of FPB who have not theretofore complied with this Section 2.07 shall thereafter look only to FBMS for the Merger Consideration, any cash in lieu of fractional shares of FPB Common Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such Holder is entitled in respect of each share of FPB Common Stock such shareholder 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 FPB Common Stock are not surrendered or the payment for them is not claimed prior to the date on which such shares of FBMS Common Stock or cash would otherwise escheat to or become the property of any governmental unit or agency, the unclaimed items shall, to the extent permitted by the law of abandoned property and any other applicable Law, become the property of FBMS (and to the extent not in its possession shall 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 shall be liable to any Holder represented by any Certificate or Book-Entry Share for any amounts delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. FBMS and the Exchange Agent shall be entitled to rely upon the stock transfer books of FPB to establish the identity of those Persons entitled to receive the Merger Consideration specified in this Agreement, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of any shares of FPB Common Stock represented by any Certificate or Book-Entry Share, FBMS and the Exchange Agent shall 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)FBMS or the Exchange Agent, as applicable, shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any Holder such amounts as FBMS is required to deduct and withhold under applicable Law. Any amounts so deducted and withheld shall be remitted to the appropriate Governmental Authority and upon such remittance shall be treated for all purposes of this Agreement as having been paid to the Holder in

7

respect of which such deduction and withholding was made by FBMS or the Exchange Agent, as applicable.

Section 2.08Rights of Certificate Holders after the Effective Time.

(a) All shares of FBMS Common Stock to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time and if ever a dividend or other distribution is declared by FBMS in respect of the FBMS Common Stock, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares of FBMS Common Stock issuable pursuant to this Agreement. No dividends or other distributions in respect of the FBMS Common Stock shall 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 II. Subject to the effect of applicable Laws, following surrender of any such Certificate or Book-Entry Share, there shall be issued and/or paid to the Holder of the certificates representing whole shares of FBMS 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 whole shares of FBMS Common Stock and not paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of FBMS Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender.

(b)In the event of a transfer of ownership of a Certificate representing FPB Common Stock that is not registered in the stock transfer records of FPB, the proper amount of cash and/or shares of FBMS Common Stock shall be paid or issued in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such FPB Common Stock shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment or issuance shall pay any transfer or other similar Taxes required by reason of the payment or issuance to a person other than the registered Holder of the Certificate or establish to the satisfaction of FBMS that the Tax has been paid or is not applicable.

Section 2.09Anti-Dilution Provisions. If the number of shares of FBMS Common Stock or FPB Common Stock issued and outstanding prior to the Effective Time shall 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 shall be any extraordinary dividend or distribution with respect to such stock, and the record date therefor shall be prior to the Effective Time, an appropriate and proportionate adjustment shall be made to the Merger Consideration to give holders of FPB Common Stock the same economic effect as contemplated by this Agreement prior to such event.

Neither FPB nor any of its officers, directors or any of its Subsidiaries has employed any broker or finder or incurred, nor will it incur, any liability for any broker’s fees, commissions or finder’s fees in connection with any of the transactions contemplated by this Agreement, except that FPB has engaged, and will pay a fee or commission to Sandler O’Neill & Partners, L.P. (“FPB Financial Advisor”), in accordance with the terms of a letter agreement between FPB Financial Advisor and FPB, a true, complete and correct copy of which has been previously delivered by FPB to FBMS.

17

(c)All FPB Benefit Plans are in compliance in all material respects in form and operation with all applicable Laws, including ERISA and the Code. Each FPB Benefit Plan which is intended to be qualified under Section 401(a) of the Code (“FPB 401(a) Plan”) has received a favorable opinion, determination or advisory letter from the IRS, and to FPB’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 or the loss of the qualification of such FPB 401(a) Plan under Section 401(a) of the Code, and nothing has occurred that would be expected to result in the FPB 401(a) Plan ceasing to be qualified under Section 401(a) of the Code. All FPB Benefit Plans have been administered in all material respects in accordance with their terms. There is no pending or, to FPB’s Knowledge, threatened litigation or regulatory action relating to the FPB Benefit Plans. Neither FPB nor any of its Subsidiaries has engaged in a transaction with respect to any FPB Benefit Plan, including a FPB 401(a) Plan that could subject FPB or any of its Subsidiaries to a tax or penalty under any Law including, but not limited to, Section 4975 of the Code or Section 502(i) of ERISA. No FPB 401(a) Plan has been submitted under or been the subject of an IRS voluntary compliance program submission that is still outstanding or that has not been fully corrected in accordance with a compliance statement issued by the IRS with respect to any applicable failures. There are no audits, inquiries or proceedings pending or, to FPB’s Knowledge, threatened by the IRS or the Department of Labor with respect to any FPB Benefit Plan.

Neither FPB nor any ERISA Affiliate has ever maintained a plan subject to Title IV of ERISA or Section 412 of the Code. None of FPB or any ERISA Affiliate has contributed to (or been obligated to contribute to) a “multiemployer plan” within the meaning of Section 3(37) of ERISA or a “multiple employer plan” within the meaning of ERISA Sections 4063 or 4064 or Code Section 413(c) at any time. Neither FPB nor any of its Subsidiaries or ERISA Affiliates have incurred, and there are no circumstances under which they could reasonably be expected to incur, liability under Title IV of ERISA (regardless of whether based on contributions of an ERISA Affiliate). Neither FPB nor any of its Subsidiaries has ever sponsored, maintained or participated in a multiple employer welfare arrangement as defined in ERISA Section 3(40). No notice of a “reportable event” within the meaning of Section 4043 of ERISA has been required to be filed for any FPB Benefit Plan or by any ERISA Affiliate or will be required to be filed, in either case, in connection with the transactions contemplated by this Agreement.

(e)All contributions required to be made with respect to all FPB Benefit Plans have been timely made. No FPB Benefit Plan or single employer plan of an ERISA Affiliate has an “accumulated funding deficiency” (whether or not waived) within the meaning of Section 412 of the Code or Section 3012 of ERISA and no ERISA Affiliate has an outstanding funding waiver.

(f)Except as set forth in FPB Disclosure Schedule 3.15(f), no FPB Benefit Plan provides life insurance, medical, surgical, hospitalization or other employee welfare benefits to any FPB Employee, or any of their affiliates, upon or following his or her retirement or termination of employment for any reason, except as may be required by Law.

FPB may amend or terminate any such FPB Benefit Plan at any time without incurring any liability thereunder for future benefits coverage at any time after such termination.

(h)Except as otherwise provided for in this Agreement or as set forth in FPB Disclosure Schedule 3.15(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 current or former FPB Employee to retention or other bonuses, parachute payments, non-competition payments, or any other payment, (ii) entitle any current or former FPB Employee to unemployment compensation, severance pay or any increase in severance pay upon any termination of employment, (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, increase the amount payable or trigger any other obligation pursuant to, any of the FPB Benefit Plans, (iv) result in any breach or violation of, or a default under, any of the FPB 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 FPB or, after the consummation of the transactions contemplated hereby, FBMS or any of its Subsidiaries, to merge, amend or terminate any of the FPB Benefit Plans.

(b)FPB and each of its Subsidiaries have properly withheld and paid over to the appropriate Governmental Authority all material Taxes required to have been withheld and paid over in connection with any amounts paid or owing to any employee, independent contractor, creditor, stockholder or other Person, and have complied in all material respects with all applicable reporting requirements related to Taxes.

After the Registration Statement is declared effective under the Securities Act, FPB, at its own expense, shall promptly mail or cause to be mailed the Proxy Statement-Prospectus to its shareholders.

(b)FBMS will advise FPB, promptly after FBMS receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of FBMS Common Stock for offering or sale in any jurisdiction, of the initiation or threat of any proceeding for any such purpose, or of any request by the SEC for the amendment or supplement of the Registration Statement or upon the receipt of any comments (whether written or oral) from the SEC or its staff. FBMS will provide FPB and its counsel with a reasonable opportunity to review and comment on the Registration Statement and the Proxy Statement-Prospectus, and 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, and FBMS will provide FPB and its counsel with a copy of all such filings made with the SEC. If at any time prior to the Effective Time there shall occur any event that should be disclosed in an amendment or supplement to the Proxy Statement-Prospectus or the Registration Statement so that either such document 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, FBMS shall use its commercially reasonable efforts to promptly prepare and file such amendment or supplement with the SEC (if required under applicable Law) and cooperate with FPB to mail such amendment or supplement to FPB shareholders (if required under applicable Law).

(c)FBMS will use its commercially reasonable efforts to cause the shares of FBMS 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 5.06Regulatory Filings; Consents.

(a)Each of FBMS and FPB and their respective Subsidiaries shall cooperate and use their respective reasonable best efforts (i) to promptly prepare all documentation (including the Registration Statement and the Proxy Statement-Prospectus), and to effect all 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, the Regulatory Approvals and all other consents and approvals of a Governmental Authority 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 shall be deemed to require FBMS or any of its Subsidiaries or FPB or any of its Subsidiaries to take any 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 FPB) on the condition (financial or otherwise), results of operations, liquidity, assets or deposit liabilities, properties or business of FBMS, FPB, the Surviving Entity or the Surviving Bank, after giving effect to the Merger (“Burdensome Condition”). FBMS and FPB 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 FBMS or FPB to any Governmental Authority in connection with the transactions contemplated by this Agreement. Each Party shall 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 filing made in connection with the transactions contemplated by this Agreement with any Governmental Authority. In addition, FBMS and FPB shall each furnish to the other for review a copy of each such filing made in connection with the transactions contemplated by this Agreement with any Governmental Authority prior to its filing.

(b)FPB will use its commercially reasonable efforts, and FBMS shall reasonably cooperate with FPB at FPB’s request, to obtain all consents, approvals, authorizations, waivers or similar affirmations described on FPB Disclosure Schedule 3.12(c). Each Party will notify the other Party promptly and shall 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). FPB will consult with FBMS and its representatives as often as practicable under the circumstances so as to permit FPB and FBMS 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 5.07Publicity. FBMS and FPB shall consult with each other before issuing any press release with respect to this Agreement or the transactions contemplated hereby and shall not issue any such press release or make any such public statement without the prior consent of the other Party, which shall not be unreasonably delayed or withheld; provided, however, that a party

44

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. It is understood that FBMS shall assume primary responsibility for the preparation of joint press releases relating to this Agreement, the Merger and the othder transactions contemplated hereby.

Section 5.08Access; 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, FPB agrees to afford FBMS 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 FPB’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 FBMS may reasonably request and FPB shall use its commercially reasonable efforts to provide any appropriate notices to employees and/or customers in accordance with applicable Law and FPB’s privacy policy and, during such period, FPB shall furnish to FBMS, upon FBMS’s reasonable request, all such other information concerning the business, properties and personnel of FPB and its Subsidiaries that is substantially similar in scope to the information provided to FBMS 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, FBMS agrees to furnish to FPB such information as FPB may reasonably request concerning the business of FBMS and its Subsidiaries that is substantially similar in scope to the information provided to FPB in connection with its diligence review prior to the date of this Agreement.

(c)As promptly as reasonably practicable after they become available, FPB will furnish to FBMS copies of the board packages distributed to the board of directors of FPB 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 FPB or any committee thereof relating to the financial performance and risk management of FPB.

(d)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, FPB agrees to provide to FBMS (i) a copy of each report filed by FPB or any of its Subsidiaries with a Governmental Authority, (ii) a copy of FPB’s monthly loan trial balance, and (iii) a copy of FPB’s monthly statement of condition and profit and loss statement and, if requested by FBMS, a copy of FPB’s daily statement of condition and daily profit and loss statement, in each case, which shall be provided as promptly as reasonably practicable after it is filed or prepared, as

45

applicable. FPB further agrees to provide FBMS, no later than ten (10) Business Days following the end of each calendar month following the date hereof, any supplements to FPB Disclosure Schedule 3.19, FPB Disclosure Schedule 3.22(a), and FPB Disclosure Schedule 3.22(b) that would be required if the references to August 31, 2018 in each corresponding representation and warranty of FPB were changed to the date of the most recently ended calendar month.

(e)No investigation by a Party or its representatives shall 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 FBMS and FPB to consummate the transactions contemplated hereby.

(f)Notwithstanding anything to the contrary in this Section 5.08, FPB shall not be required to copy FBMS 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 FPB’s board of directors has been advised by counsel that such distribution to FBMS may violate a confidentiality obligation or fiduciary duty or any Law or regulation, or may result in a waiver of FPB’s attorney-client privilege. In the event any of the restrictions in this Section 5.08(f) shall apply, FPB shall 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 5.09No Solicitation by FPB; Superior Proposals.

(a)Except as permitted by Section 5.09(b), FPB shall not, and shall 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 FPB or any of FPB’s Subsidiaries (collectively, the “FPB 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 FBMS) any information or data with respect to FPB 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 FPB 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 FPB Representatives, whether or not such FPB Representative is so authorized and whether or not such FPB Representative is purporting to act on behalf of FPB or otherwise, shall be deemed to be a breach of this Agreement by FPB. FPB and its Subsidiaries shall, and shall cause each of the FPB 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.

46

For purposes of this Agreement, “Acquisition Proposal” means any inquiry, offer or proposal (other than an inquiry, offer or proposal from FBMS), 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 (A) any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving FPB or any of its Subsidiaries; (B) 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 FPB or any of its Subsidiaries; (C) 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 20% or more of the votes attached to the outstanding securities of FPB or any of its Subsidiaries; (D) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning 20% or more of any class of equity securities of FPB or any of its Subsidiaries; or (E) 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 FPB or any of its Subsidiaries, the shareholders of such third party) acquiring, directly or indirectly, more than 50% of the outstanding FPB Common Stock or more than 50% of the assets of FPB and its Subsidiaries, taken as a whole, for consideration consisting of cash and/or securities and (ii) that the board of directors of FPB 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 FBMS in response to such Acquisition Proposal, as contemplated by Section 5.09(c), 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 FPB from a financial point of view than the Merger.

(b)Notwithstanding Section 5.09(a) or any other provision of this Agreement, prior to the date of the FPB Meeting, FPB may take any of the actions described in Section 5.09(a) if, but only if, (i) FPB has received a bona fide unsolicited written Acquisition Proposal that did not result from a breach of Section 5.09(a); (ii) the board of directors of FPB 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) the failure to take such actions more likely than not would cause it to violate its fiduciary duties to FPB’s shareholders under applicable Law; (iii) FPB has provided FBMS with at least two (2) Business Days’ prior notice of such determination; and (iv) prior to furnishing or affording access to any information or data with respect to FPB or any of its Subsidiaries or otherwise relating to an Acquisition Proposal, FPB receives from such Person a confidentiality agreement with terms no less favorable to FPB than those contained in the confidentiality agreement with FBMS. FPB shall promptly provide to FBMS any non-public

47

information regarding FPB or its Subsidiaries provided to any other Person which was not previously provided to FBMS, such additional information to be provided no later than the date of provision of such information to such other party.

(c)FPB shall promptly (and in any event within twenty-four (24) hours) notify FBMS 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, FPB or the FPB Representatives, in each case in connection with any Acquisition Proposal, and such notice shall 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 party making such offer or proposal under an effective confidentiality agreement). FPB agrees that it shall keep FBMS 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 FPB nor any committee thereof shall (i) withdraw, qualify, amend or modify, or propose to withdraw, qualify, amend or modify, in a manner adverse to FBMS in connection with the transactions contemplated by this Agreement (including the Merger), the FPB Recommendation, fail to reaffirm the FPB Recommendation within three (3) Business Days following a request by FBMS, or make any statement, filing or release, in connection with the FPB Meeting or otherwise, inconsistent with the FPB Recommendation (it being understood that taking a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification of the FPB Recommendation); (ii) approve or recommend, or propose to approve or recommend, any Acquisition Proposal; or (iii) enter into (or cause FPB 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 5.09(b)) or (B) requiring FPB to abandon, terminate or fail to consummate the Merger or any other transaction contemplated by this Agreement.

(e)Notwithstanding Section 5.09(d), prior to the date of the FPB Meeting, the board of directors of FPB may withdraw, qualify, amend or modify the FPB Recommendation (a “FPB Subsequent Determination”) after the third (3^rd) Business Day following FBMS’s receipt of a notice (the “Notice of Superior Proposal”) from FPB advising FBMS that the board of directors of FPB has decided that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of Section 5.09(a)) constitutes a Superior Proposal if, but only if, (i) the board of directors of FPB 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 more likely than not would cause it to violate its fiduciary duties to FPB’s shareholders under applicable Law, (ii) during the four (4) Business Day period after receipt of the Notice of Superior Proposal by FBMS (the “Notice Period”), FPB and the board of directors of FPB shall have cooperated and negotiated in good faith with FBMS to make such adjustments, modifications or amendments to the terms and conditions of this Agreement as would enable FPB to proceed with the FPB Recommendation without a FPB Subsequent Determination; provided, however, that

48

FBMS shall 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 FBMS since its receipt of such Notice of Superior Proposal, the board of directors of FPB has again in good faith made the determination (A) in clause (i) of this Section 5.09(e) and (B) that such Acquisition Proposal constitutes a Superior Proposal. In the event of any material revisions to the Superior Proposal, FPB shall be required to deliver a new Notice of Superior Proposal to FBMS and again comply with the requirements of this Section 5.09(e), except that the Notice Period shall be reduced to three (3) Business Days.

(f)Notwithstanding any FPB Subsequent Determination, this Agreement shall be submitted to FPB’s shareholders at the FPB Meeting for the purpose of voting on the approval of this Agreement and the transactions contemplated hereby (including the Merger) and nothing contained herein shall be deemed to relieve FPB of such obligation; provided, however, that if the board of directors of FPB shall have made a FPB Subsequent Determination with respect to a Superior Proposal, then the board of directors of FPB may recommend approval of such Superior Proposal by the shareholders of FPB and may submit this Agreement to FPB’s shareholders without recommendation, in which event the board of directors of FPB shall 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 FPB’s shareholders in the Proxy Statement-Prospectus or an appropriate amendment or supplement thereto.

(g)Nothing contained in this Section 5.09 shall prohibit FPB or the board of directors of FPB from complying with FPB’s obligations required under Rule 14e-2(a) promulgated under the Exchange Act (as if such rule was applicable to FPB); provided, however, that any such disclosure relating to an Acquisition Proposal (other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) shall be deemed a change in the FPB Recommendation unless the board of directors of FPB reaffirms the FPB Recommendation in such disclosure.

Section 5.10Indemnification.

(a)For a period of six (6) years from and after the Effective Time, and in any event subject to the provisions of Section 5.10(c)(iv), FBMS shall indemnify and hold harmless the present and former directors, officers, employees and agents of FPB 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 shall require the prior written consent of FBMS, which consent shall 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 FPB 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 FPB and its Subsidiaries in effect on the date of this Agreement to the extent permitted by applicable Law.

49

(b)In connection with the indemnification provided pursuant to Section 5.10, FBMS and/or an FBMS Subsidiary will advance expenses, promptly after statements therefor are received, to each FPB Indemnified Party, to the same extent permitted under the organizational documents of FPB 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 FPB Indemnified Party or multiple Indemnified Parties, it being understood that they collectively shall only be entitled to one counsel and one local counsel in each applicable jurisdiction where necessary or appropriate (unless a conflict shall exist between them in which case they may retain separate counsel), all such counsel shall be reasonably satisfactory to FBMS.

(c)Any Indemnified Party wishing to claim indemnification under this Section 5.10 shall promptly notify FBMS upon learning of any Claim, provided that, failure to so notify shall not affect the obligation of FBMS under this Section 5.10, unless, and only to the extent that, FBMS 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) FBMS shall have the right to assume the defense thereof and FBMS shall 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) FBMS shall not be liable for any settlement effected without its prior written consent and (iv) FBMS shall 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 shall determine that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable Laws and regulations, whether or not related to banking Laws.

(d)For a period of six (6) years following the Effective Time, FBMS will maintain director’s and officer’s liability insurance (herein, “D&O Insurance”) that serves to reimburse the present and former officers and directors of FPB or its Subsidiaries (determined as of the Effective Time) with respect to claims against such directors and officers arising from facts or events occurring before the Effective Time (including the transactions contemplated hereby), 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 FPB; provided that, if FBMS is unable to maintain or obtain the insurance called for by this Section 5.10, FBMS will provide as much comparable insurance as is reasonably available (subject to the limitations described below in this Section 5.10(d)); and provided, further, that officers and directors of FPB or its Subsidiaries may be required to make application and provide customary representations and warranties to the carrier of the D&O Insurance for the purpose of obtaining such insurance. In no event shall FBMS be required to expend for such tail insurance a premium amount in excess of an amount equal to 250% of the annual premiums paid by FPB 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, FBMS shall obtain tail insurance coverage or a separate tail insurance policy with the greatest coverage available for a cost not exceeding the Maximum D&O Tail Premium.

50

(e)Nothing contained in this Section 5.10 or any other provision of this Agreement shall limit any right to indemnification which any current or former director, officer, employee or agent of FPB or Florida Parishes Bank may have under applicable law or regulation or FPB’s articles of incorporation, bylaws or the equivalent documents of Florida Parishes Bank, as applicable, in each case as in effect on the date hereof, which FBMS agrees to honor in accordance with their terms.

(f)This Section 5.10 shall survive the Effective Time, is intended to benefit each FPB Indemnified Party (each of whom shall be entitled to enforce this Section against FBMS), and shall be binding on all successors and assigns of FBMS.

(g)If FBMS or any of its successors and assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) shall transfer all or substantially all of its property and assets to any individual, corporation or other entity, then, in each such case, proper provision shall be made so that the successors and assigns of FBMS and its Subsidiaries shall assume the obligations set forth in this Section 5.10.

Section 5.11Employees; Benefit Plans.

(a)Following the Effective Time, FBMS shall maintain or cause to be maintained employee benefit plans for the benefit of employees who are full time employees of FPB on the Closing Date and who become employees of FBMS (“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 FBMS; provided, however, that in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of FBMS. FBMS shall give the Covered Employees credit for their prior service with FPB (i) for purposes of eligibility (including initial participation and eligibility for current benefits) and vesting under any qualified or non-qualified employee benefit plan maintained by FBMS and in which Covered Employees may be eligible to participate and (ii) for all purposes under any welfare benefit plans, vacation plans, severance plans and similar arrangements maintained by FBMS.

(b)With respect to any employee benefit plan of FBMS that is a health, dental, vision or other welfare plan in which any Covered Employee is eligible to participate, for the plan year in which such Covered Employee is first eligible to participate, FBMS shall use its commercially reasonable efforts to (i) cause any pre-existing condition limitations, eligibility waiting periods or evidence of insurability requirements under such FBMS 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 FPB Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time, and (ii) recognize any health, dental, vision or other welfare expenses incurred by such Covered Employee and his or her covered dependents in the year that includes the Closing Date (or, if later, the year in which such Covered Employee is first eligible to participate) for purposes of any applicable copayment, deductibles and annual out of pocket expense requirements under any such health, dental, vision or other welfare plan.

51

(c)Following the Effective Time, The First shall credit each Covered Employee with an amount of paid time off equal to such Covered Employee’s accrued but unused paid time off at Florida Parishes Bank (“Carryover PTO”), provided that The First may allocate the Carryover PTO and between vacation leave and sick leave in its discretion.

(d)FPB shall cause Florida Parishes Bank to take all necessary actions to terminate the Florida Parishes Bank 401(k) Plan, effective as the date immediately preceding the Effective Time of the Merger, subject to the occurrence of the Effective Time. FPB shall provide FBMS with evidence that the Florida Parishes Bank 401(k) plan has been terminated and provide copies of the appropriate resolutions terminating the plan (the form and substance of which shall be subject to review and approval by FBMS, which will not be unreasonably withheld) not later than the day immediately preceding the Effective Time. The accounts of all participants and beneficiaries in the Florida Parishes Bank 401(k) Plan shall become fully vested upon termination of such plan.

(e)Prior to the Effective Time, FPB shall take, and shall cause its Subsidiaries to take, all actions requested by FBMS that may be necessary or appropriate to, conditioned on the occurrence of the Effective Time, (i) cause one or more FPB Benefits Plans not covered above to terminate as of the Effective Time, or as of the date immediately preceding the Effective Time, (ii) cause benefit accruals and entitlements under any FPB Benefit Plan to cease as of the Effective Time, or as of the date immediately preceding the Effective Time, (iii) cause the continuation on and after the Effective Time of any contract, arrangement or insurance policy relating to any FPB Benefit Plan for such period as may be requested by FBMS, or (iv) facilitate the merger of any FPB Benefit Plan into any employee benefit plan maintained by FBMS. Additionally, FPB and Florida Parishes Bank will take any and all actions reasonably requested by FBMS related to ensuring the compliance of all FPB Benefit Plans with applicable law, including but not limited to filing any necessary “top hat” filings or corrections. All resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this Section 5.11(e) shall be subject to FBMS’s reasonable prior review and approval, which shall not be unreasonably withheld, conditioned or delayed.

(f)Any employee of FPB or Florida Parishes Bank that becomes an employee of FBMS or The First at the Effective Time who is terminated within one year following the Effective Time (other than for cause, death, disability, normal retirement or voluntarily resignation) shall receive a severance payment calculated in accordance with the policy set forth on FBMS Disclosure Schedule 5.11(f), except with respect to any employees who will enter into Termination Agreements with FBMS in accordance with Section 5.11(g).

(g)FBMS shall take all actions necessary to irrevocably terminate (in accordance with Section 409A of the Code) and liquidate those portions of the employment and change in control agreements listed on FPB Disclosure Schedule 3.15(a) providing for cash severance or deferred compensation in respect of a separation from service.  In connection with such termination and liquidation, immediately following the Effective Time, FMBS will enter into Termination Agreements in the form set forth in FBMS Disclosure Schedule 5.11(g) with the individuals listed thereon. 

(h)Nothing in this Section 5.11 shall be construed to limit the right of FBMS (including, following the Closing Date, FPB) to amend or terminate any FPB Benefit Plan or other

52

employee benefit plan, to the extent such amendment or termination is permitted by the terms of the applicable plan, nor shall anything in this Section 5.11 be construed to require FBMS (including, following the Closing Date, FPB) 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 FBMS of any Covered Employee subsequent to the Effective Time shall be subject in all events to FBMS’s normal and customary employment procedures and practices, including customary background screening and evaluation procedures, and satisfactory employment performance.

(i)For purposes of this Section 5.10, (i) “employees of FPB” shall include employees of FPB or any of its Subsidiaries, (ii) “employees of FBMS” shall include employees of FBMS or any of its Subsidiaries, (iii) all references to FPB shall include each of the Subsidiaries of FPB, and (iv) all references to FBMS shall include each of the Subsidiaries of FBMS.

Section 5.12Notification of Certain Changes.

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 shall 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 shall not be

73

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.

Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective successors and permitted assigns.

(c)The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of his, her or its obligations hereunder and the consummation by Shareholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a default under, any agreement, instrument, contract or other obligation or any order, arbitration award, judgment or decree to which Shareholder is a party or by which Shareholder is bound, or any statute, rule or regulation to which Shareholder is subject or, in the event that Shareholder is a corporation, partnership, trust or other entity, any charter, bylaw or other organizational document of Shareholder.

(d)Shareholder is the record and beneficial owner of, or is the trustee that is the record holder of, and whose beneficiaries are the beneficial owners of, and has good title to all of the Shares, and the Shares are owned free and clear of any liens, security interests, charges or other encumbrances. The Shares do not include shares over which Shareholder exercises control in a fiduciary capacity for any other person or entity that is not an Affiliate of Shareholder, and no representation by Shareholder is made with respect thereto. Shareholder has the right to vote the Shares, and none of the Shares is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting of the Shares, except as contemplated by this Agreement. Shareholder does not own, of record or beneficially, any shares of capital stock of FPB other than the Shares or any other securities convertible into or exercisable or exchangeable for such capital stock, other than any FPB Restricted Shares.

Section 4. No Solicitation. From and after the date hereof until the termination of this Agreement pursuant to Section 6, Shareholder, solely in his, her or its capacity as a shareholder of FPB, shall not, nor shall such Shareholder authorize any partner, officer, director, advisor or representative of, such Shareholder or any of his, her or its Affiliates to, directly or indirectly (and, to the extent applicable to Shareholder, such Shareholder shall use commercially reasonable efforts to prohibit any of his, her or its representatives or Affiliates to), (a) 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, (b) except in his capacity as a director or officer of FPB and under circumstances for which such actions are permitted for FPB under the Merger Agreement, participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any person (other than FBMS) any information or data with respect to FPB or otherwise relating to an Acquisition Proposal, (c) enter into any agreement, agreement in principle or letter of intent with respect to an 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, (d) solicit proxies with respect to an Acquisition Proposal (other than the Merger Agreement) or otherwise encourage or assist any party in taking or planning any action that would compete with, restrain or otherwise serve to interfere with or inhibit the timely consummation of the Merger in accordance with the

3

terms of the Merger Agreement, or (e) initiate a shareholders’ vote or action by consent of FPB’s shareholders with respect to an Acquisition Proposal.

Section 5. Specific Performance; Remedies; Attorneys’ Fees. Shareholder acknowledges that it is a condition to the willingness of FBMS to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to FBMS if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, FBMS will not have an adequate remedy at law or in equity. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that FBMS has an adequate remedy at Law. Shareholder further agrees that Shareholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with FBMS’ seeking or obtaining such equitable relief. In addition, after discussing the matter with Shareholder, FBMS shall have the right to inform any third party that FBMS reasonably believes to be, or to be contemplating, participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement, of the terms of this Agreement and of the rights of FBMS hereunder, and that participation by any such persons with Shareholder in activities in violation of Shareholder’s agreement with FBMS set forth in this Agreement may give rise to claims by FBMS against such third party.

Section 6. Term of Agreement; Termination. The term of this Agreement shall commence on the date hereof. This Agreement may be terminated at any time prior to consummation of the transactions contemplated by the Merger Agreement by the mutual written agreement of the parties hereto, and shall be automatically terminated upon the earlier to occur of (a) the Effective Time, (b) the amendment of the Merger Agreement in any manner that materially and adversely affects any of Shareholder’s rights set forth therein (including, for the avoidance of doubt, any reduction to the Merger Consideration), (c) termination of the Merger Agreement or (d) two (2) years from the date hereof. Upon such termination, no party shall have any further obligations or liabilities hereunder; provided, however, that such termination shall not relieve any party from liability for any breach of this Agreement prior to such termination.

Section 7. Entire Agreement. This Agreement represents the entire understanding of the parties hereto with reference to the transactions contemplated hereby, and this Agreement supersedes any and all other oral or written agreements heretofore made.

Section 8. Modification and Waiver. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing signed by each party. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of dissimilar provisions or conditions at the same or any prior subsequent time.

Section 9. Severability. In the event that any one or more provisions of this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect, by any court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement and the parties shall use their commercially reasonable efforts to

4

substitute a valid, legal and enforceable provision which, insofar as practical, implements the purposes and intents of this Agreement.

Section 10. Capacity as Shareholder. This Agreement shall apply to Shareholder solely in his, her or its capacity as a shareholder of FPB, and it shall not apply in any manner to Shareholder in his, her or its capacity as a director or officer of FPB, if applicable. Nothing contained in this Agreement shall be deemed to apply to, or limit in any manner, the obligations of Shareholder to comply with his, her or its fiduciary duties as a director or officer of FPB, if applicable.

Section 11. Governing Law. This Agreement shall be governed by, and interpreted and enforced in accordance with, the internal, substantive laws of the State of Mississippi, without regard for conflict of law provisions.

Section 12. Jurisdiction.

Each party consents to the jurisdiction of such Mississippi court in any such civil action, counterclaim, proceeding or litigation and waives any objection to the laying of venue of any such civil action, counterclaim, proceeding or litigation in such Mississippi court. Service of any court paper may be effected on such party by mail, as provided in this letter, or in such other manner as may be provided under applicable Laws.

Section 13. WAIVER OF JURY TRIAL. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 13.

Section 14. Waiver of Appraisal Rights; Further Assurances. To the extent permitted by applicable law, Shareholder hereby waives any rights of appraisal or rights to dissent from the Merger or demand fair value for his, her or its Shares in connection with the Merger, in each case, that Shareholder may have under applicable law. From time to time prior to the termination of this Agreement, at FBMS’s request and without further consideration, Shareholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or desirable to effect the actions and consummate the transactions contemplated by this Agreement. Shareholder further agrees not to commence or participate in, and to take all actions

5

necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against FBMS, The First Bank, FPB, Florida Parishes Bank or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger.

Section 15. Disclosure. Shareholder hereby authorizes FPB and FBMS to publish and disclose in any announcement or disclosure required by the Securities and Exchange Commission and in the Proxy Statement-Prospectus such Shareholder’s identity and ownership of the Shares and the nature of Shareholder’s obligations under this Agreement; provided, however, that FBMS shall provide Shareholder written drafts of any such disclosure and consider in good faith Shareholder’s comments thereto.

Section 16. Ownership. Nothing in this Voting Agreement shall be construed to give FBMS any rights to exercise or direct the exercise of voting power as owner of the Shares or to vest in FBMS any direct or indirect ownership or incidents of ownership of or with respect to any of the Shares. All rights, ownership and economic benefits of and relating to the Shares shall remain vested in and belong to the Shareholder, notwithstanding the provisions of this Voting Agreement, and FBMS shall have no authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of FPB or to exercise any power or authority to direct the Shareholder in voting any of the Shares, except as otherwise expressly provided herein.

Section 17. Fiduciary Duty. No provision of this Agreement shall preclude or in any way limit the Shareholder (or any representative of the Shareholder) from exercising his or her fiduciary duties as a member of the Board of Directors or an officer of FPB.

Section 18. Counterparts. This Agreement may be executed and delivered by facsimile or by electronic data file and in one or more counterparts, all of which shall be considered one and the same agreement and shall 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.

EXHIBIT C

FOrm OF NON-COMPETITION AND NON-DISCLOSURE AGREEMENT

This Non-Competition and Non-Disclosure Agreement (the “Agreement”), is dated as of November 6, 2018, by and between ____________________________, an individual resident of the State of Louisiana (“Director”), and The First Bancshares, Inc., a Mississippi corporation (“FBMS”). All capitalized terms used but not defined herein shall have the meanings assigned to them in the Merger Agreement (defined below).

RECITALS:

WHEREAS, concurrently with the execution of this Agreement, FBMS and FPB Financial Corp., a Louisiana corporation (“FPB”), are entering into an Agreement and Plan of Merger (as such agreement may be subsequently amended or modified, the “Merger Agreement”), pursuant to which (i) FPB will merge with and into FBMS, with FBMS as the surviving entity, and (ii) Florida Parishes Bank, a federal savings bank and wholly-owned subsidiary of FPB, will merge with and into The First, National Association, a national banking association and wholly-owned subsidiary of FBMS (“The First”), with The First as the surviving bank (collectively, the “Merger”);

WHEREAS, Director is a shareholder of FPB and, as a result of the Merger and pursuant to the transactions contemplated by the Merger Agreement, Director is expected to receive significant consideration in exchange for the shares of FPB Common Stock held by Director;

WHEREAS, as of and prior to the date hereof, Director serves and has served as a member of the Board of Directors of FPB or Florida Parishes Bank, and, therefore, Director has knowledge of the Confidential Information and Trade Secrets (each as hereinafter defined);

WHEREAS, as a result of the Merger, FBMS will succeed to all of the Confidential Information and Trade Secrets, for which FBMS as of the Effective Time will have paid valuable consideration and desires reasonable protection; and

WHEREAS, it is a material prerequisite to the consummation of the Merger that each director of FPB and Florida Parishes Bank, including Director, enter into this Agreement.

AGREEMENT:

NOW, THEREFORE, in consideration of these premises and the mutual covenants and undertakings herein contained, FBMS and Director, each intending to be legally bound, covenant and agree as follows:

Section 1. Restrictive Covenants.

(a)Director acknowledges that (i) FBMS has separately bargained for the restrictive covenants in this Agreement; and (ii) the types and periods of restrictions imposed by the

covenants in this Agreement are fair and reasonable to Director and such restrictions will not prevent Director from earning a livelihood.

(b)Having acknowledged the foregoing, solely in the event that the Merger is consummated, Director covenants and agrees with FBMS as follows:

(i)From and after the Effective Time, Director will not disclose or use any Confidential Information or Trade Secrets for so long as such information remains Confidential Information or a Trade Secret, as applicable, for any purpose, except for any disclosure that is required by applicable Law. In the event that Director is required by Law to disclose any Confidential Information, Director will: (A) if and to the extent permitted by such Law, provide FBMS with prompt notice of such requirement prior to the disclosure so that FBMS may waive the requirements of this Agreement or seek an appropriate protective order at FBMS’s sole expense; and (B) use commercially reasonable efforts to obtain assurances that any Confidential Information disclosed will be accorded confidential treatment. If, in the absence of a waiver or protective order, Director is nonetheless, in the opinion of his or her counsel, required to disclose Confidential Information, disclosure may be made only as to that portion of the Confidential Information that counsel advises Director is required to be disclosed. Nothing contained in this Agreement limits the Director’s ability to file a charge or complaint with the Equal Employment Opportunity Commission, the Federal Deposit Insurance Corporation, the Board of Governors of the Federal Reserve System, the Securities and Exchange Commission or any other federal, state or local governmental agency or commission that has jurisdiction over FPB or any of its subsidiaries or affiliates (the “Government Agencies”). The Director further understands that this Agreement does not limit his ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to FPB or any of its subsidiaries or affiliates. This Agreement does not limit the Director’s right to receive an award for information provided to any Government Agencies. In addition, pursuant to the Defend Trade Secrets Act of 2016, the Director understands that an individual may not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made (A) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding.  Further, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the employer's trade secrets to the attorney and use the trade secret information in the court proceeding if the individual (y) files any document containing the trade secret under seal; and (z) does not disclose the trade secret, except pursuant to court order.

(ii)Except as expressly provided on Schedule I to this Agreement, for a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not (except on behalf of or with the prior written consent of FBMS), on Director’s own behalf or in the service or on behalf of others, solicit or attempt to solicit any customer of FBMS, The First, FPB or Florida Parishes Bank (each a “Protected Party”), including actively sought prospective customers of Florida Parishes Bank as of the Effective Time, for the purpose of providing products or services that are Competitive (as hereinafter defined) with those offered or provided by any Protected Party.

2

(iii)Except as expressly provided on Schedule I to this Agreement, for a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not (except on behalf of or with the prior written consent of FBMS), either directly or indirectly, on Director’s own behalf or in the service or on behalf of others, act as a director, manager, officer or employee of any business which is the same as or essentially the same as the business conducted by any Protected Party and which has an office located within the Restricted Territory.

(iv)For a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not, on Director’s own behalf or in the service or on behalf of others, solicit or recruit or attempt to solicit or recruit, directly or by assisting others, any employee of any Protected Party, whether or not such employee is a full-time employee or a temporary employee of such Protected Party, whether or not such employment is pursuant to a written agreement and whether or not such employment is for a determined period or is at will, to cease working for such Protected Party; provided that the foregoing will not prevent the placement of any general solicitation for employment not specifically directed towards employees of any Protected Party or hiring any such person as a result thereof.

(c)For purposes of this Section 1, the following terms shall be defined as set forth below:

(i)“Competitive,” with respect to particular products or services, means products or services that are the same as or similar to the products or services of any Protected Party.

(ii)“Confidential Information” means data and information:

(A)relating to the business of FPB and its Subsidiaries, including Florida Parishes Bank, regardless of whether the data or information constitutes a Trade Secret;

(B)disclosed to Director or of which Director became aware as a consequence of Director’s relationship with FPB and/or Florida Parishes Bank;

(C)having value to FPB and/or Florida Parishes Bank and, as a result of the consummation of the transactions contemplated by the Merger Agreement, FBMS and/or The First; and

(D)not generally known to competitors of FPB or FBMS (including competitors to Florida Parishes Bank or The First).

Confidential Information shall include Trade Secrets, methods of operation, names of customers, price lists, financial information and projections, personnel data and similar information; provided, however, that the terms “Confidential Information” and “Trade Secrets” shall not mean data or information that (x) has been disclosed to the public, except where such public disclosure has been made by Director without authorization from FPB or FBMS, (y) has been independently developed and disclosed by others, or (z) has otherwise entered the public domain through lawful means.

3

(iii)“Restricted Territory” means each parish in Louisiana where Florida Parishes Bank operates a banking office at the Effective Time and each parish contiguous to each of such parishes.

(iv)“Trade Secret” means information, without regard to form, including technical or nontechnical data, a formula, a pattern, a compilation, a program, a device, a method, a technique, a drawing, a process, financial data, financial plans, product plans or a list of actual or potential customers or suppliers, that is not commonly known by or available to the public and which information:

(A)derives economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use; and

(B)is the subject of efforts that are reasonable under the circumstances to maintain its secrecy.

(d) Director acknowledges that irreparable loss and injury would result to FBMS upon the breach of any of the covenants contained in this Section 1 and that damages arising out of such breach would be difficult to ascertain. Director hereby agrees that, in addition to all other remedies provided at law or in equity, FBMS may petition and obtain from a court of law or equity, without the necessity of proving actual damages and without posting any bond or other security, both temporary and permanent injunctive relief to prevent a breach by Director of any covenant contained in this Section 1, and shall be entitled to an equitable accounting of all earnings, profits and other benefits arising out of any such breach. In the event that the provisions of this Section 1 should ever be determined to exceed the time, geographic or other limitations permitted by applicable Law, then such provisions shall be modified so as to be enforceable to the maximum extent permitted by Law. If such provision(s) cannot be modified to be enforceable, the provision(s) shall be severed from this Agreement to the extent unenforceable. The remaining provisions and any partially enforceable provisions shall remain in full force and effect.

Section 2. Term; Termination. This Agreement may be terminated at any time by the written consent of the parties hereto, and this Agreement shall be automatically terminated upon the earlier of (i) termination of the Merger Agreement; (ii) two (2) years following the Effective Time or (iii) upon a Change in Control of FBMS (as defined in Schedule I). For the avoidance of doubt, the provisions of Section 1 shall only become operative upon the consummation of the Merger but, in such event, shall survive the consummation of the Merger until the earlier of (a) two (2) years after the Effective Time or (b) upon a Change in Control of FBMS. Upon termination of this Agreement, no party shall have any further obligations or liabilities hereunder, except that termination of this Agreement will not relieve a breaching party from liability for any breach of any provision of this Agreement occurring prior to the termination of this Agreement.

Section 3. Notices. All notices, requests and other communications hereunder to a party shall be in writing and shall be deemed properly given if delivered (a) personally, (b) by registered or certified mail (return receipt requested), with adequate postage prepaid thereon, (c) by properly addressed electronic mail delivery (with confirmation of delivery receipt), or (d) by reputable courier service to such party at its address set forth below, or at such other address or

4

Any civil action, counterclaim, proceeding or litigation arising out of or relating to this Agreement shall be brought in the courts of record of the State of Mississippi in Forrest County or the United States District Court, Southern District of Mississippi. Each party consents to the jurisdiction of such Mississippi court in any such civil action, counterclaim, proceeding or litigation and waives any objection to the laying of venue of any such civil action, counterclaim, proceeding or litigation in such Mississippi court. Service of any court paper may be effected on such party by mail, as provided in this letter, or in such other manner as may be provided under applicable Laws.

Section 5. Modification and Waiver. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing signed by Director and FBMS.

Exhibit 99.1

The First Bancshares, Inc. Announces Agreement to Acquire FPB Financial Corp.

HATTIESBURG, MS and HAMMOND, LA, November 6, 2018 – The First Bancshares, Inc. (NASDAQ: FBMS) (“First Bancshares” or “the Company”), holding company for The First, A National Banking Association (“The First”), announced today the signing of an Agreement and Plan of Merger (the “Merger Agreement”) with FPB Financial Corp. (OTC:FPBF) (“FPB”), parent company of Florida Parishes Bank, pursuant to which First Bancshares has agreed to acquire FPB.

Under the terms of the Agreement and Plan of Merger, FPB will be merged with and into First Bancshares (the “Merger”). Upon consummation of the Merger, each FPB shareholder will receive 0.83 shares (the “Exchange Ratio”) of First Bancshares’ common stock in exchange for each share of FPB stock (the “Merger Consideration”), provided that the Exchange Ratio is subject to adjustment in accordance with the terms of the Merger Agreement in the event that the average closing price of a share of the Company’s common stock on the NASDAQ Global Select Market over the ten (10) trading days ending five (5) business days immediately prior to the closing date of the Merger is either less than $34.61 or greater than $43.39. The aggregate Merger Consideration is valued at approximately $86.1 million, based on 2,703,943 shares of FPB common stock outstanding, 198,275 in-the-money warrants to purchase shares of FPB common stock, and FBMS’ closing price of $37.14 per share as of November 5, 2018.

At September 30, 2018, FPB had approximately $382.7 million in consolidated assets, $238.5 million in net loans, $317.7 million in deposits and $44.0 million in consolidated stockholders’ equity. FPB serves the Hammond and New Orleans areas in Louisiana through seven full service offices. The transaction will expand The First’s footprint in the Gulf South and the greater New Orleans area. Additional information regarding FPB is available on the website for Florida Parishes Bank: https://www.bankfpb.com.

The Agreement and Plan of Merger has been approved by the Boards of Directors of First Bancshares and FPB. The closing of the transaction, which is expected to occur in the first quarter of 2019, is subject to customary conditions, including regulatory approval and approval by the shareholders of FPB.

Fritz W. Anderson, II, Chairman of the Board and CEO of FPB, commented, "This transaction provides our shareholders with greater liquidity, expanded geographic diversification and the opportunity to build upon the success of The First franchise. In addition to a shared legacy of strong financial performance and community advancement, the strategic synergy and cultural fit between our two banks present exciting opportunities for all of our stakeholders, including the expanded opportunities that will be available to many of the officers and staff of Florida Parishes Bank to continue their Louisiana banking careers with The First. The additional products, resources and scale provided by The First will enhance our ability to better serve our customers in south Louisiana and throughout the Gulf Coast states. Following very careful consideration by our Board of Directors, and after 96 years in business as an independent community bank, we look forward to being part of the First Bancshares team."

Combined Company

Upon completion of the transaction, the combined company, including First Bancshares’ acquisition of FMB Banking Corporation which closed on October 31, 2018, will have approximately $3.4 billion in total assets, $2.8 billion in total deposits and $2.3 billion in total loans. The Company will have 74 locations in Mississippi, Louisiana, Alabama, Florida, and Georgia.

M. Ray “Hoppy” Cole, President & Chief Executive Officer of First Bancshares and The First, commented,

“We are excited to be joining forces with FPB Financial and Florida Parishes Bank. Florida Parishes Bank is an extremely well-run company with a long, rich history centered on client service and community involvement.

Our companies share a common strategic vision of building a high performing, client focused community bank in the Gulf South. This Merger will further that objective by providing increased market share in Hammond and the greater New Orleans area. This partnership will also provide a well-respected team of local community bankers to help support further growth opportunities throughout the region.

We look forward to all we can accomplish together, growing regionally and building value for our shareholders.”

Forward Looking Statement

This news release contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. In general, forward-looking statements usually use words such as “may,” “believe,” “expect,” “anticipate,” “intend,” “will,” “should,” “plan,” “estimate,” “predict,” “continue” and “potential” or the negative of these terms or other comparable terminology, including statements related to the expected timing of the closing of the Merger, the expected returns and other benefits of the Merger, to shareholders, expected improvement in operating efficiency resulting from the Merger, estimated expense reductions resulting from the transactions and the timing of achievement of such reductions, the impact on and timing of the recovery of the impact on tangible book value, and the effect of the Merger on the Company’s capital ratios. Forward-looking statements represent management’s beliefs, based upon information available at the time the statements are made, with regard to the matters addressed; they are not guarantees of future performance. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements.

Factors that could cause or contribute to such differences include, but are not limited to (1) the risk that the cost savings and any revenue synergies from the Merger may not be realized or take longer than anticipated to be realized, (2) disruption from the Merger with customers, suppliers, employee or other business partners relationships, (3) the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, (4) the risk of successful integration of FPB’s business into the Company, (5) the failure to obtain the necessary approval by the shareholders of FPB, (6) the amount of the costs, fees, expenses and charges related to the Merger, (7) the ability by the Company to obtain required governmental approvals of the Merger, (8) reputational risk and the reaction of each of the companies’ customers, suppliers, employees or other business partners to the Merger, (9) the failure of the closing conditions in the Merger Agreement to be satisfied, or any unexpected delay in closing of the Merger, (10) the risk that the integration of FPB’s operations into the operations of the Company will be materially delayed or will be more costly or difficult than expected, (11) the possibility that the Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (12) the dilution caused by the Company’s issuance of additional shares of its common stock in the Merger, and (13) general competitive, economic, political and market conditions. Additional factors which could affect the forward looking statements can be found in the cautionary language included under the headings “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, and other documents subsequently filed by the Company with the SEC. Consequently, no forward-looking statement can be guaranteed. Neither the Company nor FPB undertakes any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For any forward-looking statements made in this new release or any related documents, the Company and FPB claim protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.
