Business Bank of Florida, Corp.

On August 23, 2021, Seacoast Banking Corporation of Florida, a Florida corporation (“Seacoast” or the “Company”), and Seacoast’s wholly-owned subsidiary, Seacoast National Bank, a national banking association (“SNB”), entered into an Agreement and Plan of Merger (the “Business Bank Merger Agreement”) with Business Bank of Florida, Corp., a Florida corporation (“Business Bank”), and Florida Business Bank, a Florida chartered bank and wholly-owned subsidiary of Business Bank. The Business Bank Merger Agreement provides that, upon the terms and subject to the conditions set forth in the merger agreement, Seacoast will acquire Business Bank pursuant to the merger of Business Bank with and into Seacoast (the “Business Bank Merger”) and the merger of Florida Business Bank with and into SNB (the “Florida Business Bank Merger”), with Seacoast surviving the Business Bank Merger as the surviving corporation and with SNB surviving the Florida Business Bank Merger as the surviving bank.

Subject to the terms and conditions of the Business Bank Merger Agreement, which has been approved by the Board of Directors of Seacoast and Business Bank, upon completion of the Business Bank Merger, each outstanding share of Business Bank common stock will be converted into the right to receive 0.7997 (the “Business Bank Exchange Ratio”) of a share of Seacoast common stock, subject to the payment of cash in lieu of fractional shares (the “Business Bank Merger Consideration”). In the event that Business Bank’s consolidated tangible shareholders’ equity is less than Business Bank’s target consolidated tangible shareholders’ equity (defined in the Business Bank Merger Agreement as $21.4 million, less the impact of after-tax permitted expenses including (i) those reasonable expenses incurred in connection with the Business Bank Merger and (ii) the fee payable to Business Bank’s financial advisor) and Florida Business Bank’s general allowance for loan and lease losses is less than 1.61% of total loans and leases outstanding (excluding loans originated under the Paycheck Protection Program (“PPP”)), then Seacoast shall have the option to adjust the Business Bank Merger Consideration downward by an amount that is reflective of the overall shortfall between Business Bank’s target consolidated tangible shareholders’ equity and Business Bank’s consolidated tangible shareholders’ equity.

At the effective time of the Business Bank Merger, each Business Bank option shall automatically cease to be outstanding, and, in consideration therefor, Seacoast shall grant to each holder of Business Bank options, as of the effective time, an option to purchase shares of Seacoast common stock pursuant to the 2021 Seacoast Incentive Plan (each, a “Substitute Seacoast Option”), on the same terms and conditions as applicable to each such Business Bank option as in effect immediately prior to the effective time, except that (A) the number of shares of Seacoast common stock subject to such Substitute Seacoast Option shall equal the product of (x) the number of shares of Business Bank common stock subject to such Business Bank option immediately prior to the effective time, multiplied by (y) the Business Bank Exchange Ratio, rounded down to the nearest whole share, and (B) the per share exercise price for the shares of Seacoast common stock issuable upon exercise of such Substitute Seacoast Option shall equal the quotient determined by dividing (x) the exercise price per share of Business Bank common stock at which such Business Bank option was exercisable immediately prior to the effective time by (y) the Business Bank Exchange Ratio, rounded up to the nearest whole cent. Each outstanding share of Seacoast common stock will remain outstanding and be unaffected by the Business Bank Merger.

The Business Bank Merger Agreement contains customary representations and warranties from both Seacoast and Business Bank and each have agreed to customary covenants, including, among others, covenants on the part of Business Bank relating to: (1) the conduct of Business Bank’s businesses during the interim period between the execution of the Business Bank Merger Agreement and the completion of the Business Bank Merger, (2) Business Bank’s obligation to convene and hold a meeting of its shareholders to consider and vote upon the approval of the Business Bank Merger Agreement, and (3) subject to certain exceptions, the recommendation by the Board of Directors of Business Bank in favor of the approval by its shareholders of the Business Bank Merger Agreement, the Business Bank Merger and the other transactions contemplated thereby (including the Florida Business Bank Merger). Business Bank has also agreed not to, and to cause its directors, officers, employees and representatives and affiliates not to, (1) initiate, solicit, encourage or knowingly encourage or facilitate inquiries or proposals with respect to any acquisition proposal, (2) engage or participate in any negotiations concerning, or with, any person relating to, any acquisition proposal or (3) subject to certain exceptions, provide any confidential or nonpublic information or data to, or have or participate in any discussions with any person relating to any acquisition proposal.

Completion of the Business Bank Merger is subject to certain customary conditions, including, among others, (1) adoption of the Business Bank Merger Agreement by Business Bank’s shareholders, (2) required regulatory consents shall have been obtained or made and be in full force and effect and all waiting periods required by law shall have expired and such required regulatory consents shall not be subject to any condition or consequence that would, after the effective time of the Business Bank Merger, have a material adverse effect on Seacoast or any of its subsidiaries, including Business Bank, (3) the absence of any order issued by any governmental authority preventing the consummation of the Business Bank Merger and the absence of any law or order enacted, entered, promulgated or enforced by any governmental entity that prohibits, restrains or makes illegal the consummation of the Business Bank Merger, (4) the effectiveness of the registration statement for the Seacoast common stock to be issued in the Business Bank Merger and (5) the approval for listing of the Seacoast common stock to be issued in the Business Bank Merger on NASDAQ.

Each party’s obligation to complete the Business Bank Merger is also subject to certain additional customary conditions, including (1) subject to certain exceptions, the accuracy of the representations and warranties of the other party, (2) performance in all material respects by the other party of its obligations under the Business Bank Merger Agreement, (3) corporate authorization, and (4) since the date of the Business Bank Merger Agreement, no fact, circumstance or event has occurred or is reasonably likely to have a material adverse effect.

In addition, Seacoast’s obligation to complete the Business Bank Merger is subject to the satisfaction of certain conditions by Business Bank, including (1) the receipt of all consents required as a result of the Business Bank Merger pursuant to certain contracts, (2) the holders of no more than 5% of Business Bank common stock shall have exercised their dissenters’ rights, (3) receipt by Seacoast of an opinion from its counsel to the effect that the Business Bank Merger will qualify as a reorganization within the meaning of the Internal Revenue Code of 1986, as amended, (4) Seacoast’s receipt of executed claims letters and restrictive covenant agreements by directors of Business Bank, (5) Business Bank’s consolidated tangible shareholders’ equity must be not less than $21.4 million and Florida Business Bank’s general allowance for loan and lease losses must not be less than 1.61% of total loans and leases outstanding (excluding PPP loans), (6) the termination by Business Bank of all outstanding equity awards and the termination by the Business Bank board of directors and shareholders of the Business Bank stock plans, (7) if required, the shareholders of Business Bank will have voted in a manner that satisfies the stockholder approval requirements for exemption under Section 280G of the Internal Revenue Code for the right of certain disqualified individuals to receive or retain certain payments and benefits and (8) the receipt of a non-foreign affidavit.

The Business Bank Merger Agreement provides certain termination rights for both Seacoast and Business Bank and further provides that a termination fee of $1.56 million will be payable by Business Bank upon termination of the Business Bank Merger Agreement under certain circumstances, including if its board of directors withdraws, qualifies or modifies its recommendation that the Business Bank shareholders approve the merger agreement in a manner adverse to Seacoast or has resolved to take such action.
