AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”) is made and entered into as of August 7, 2022 by and among Seacoast Banking Corporation of Florida, a Florida corporation (“SBC”), Seacoast National Bank, a national banking association and wholly-owned subsidiary of SBC (“SNB” and collectively with SBC, “Seacoast”), Professional Holding Corp., a Florida corporation (“Professional”), and Professional Bank, a Florida state-chartered bank and wholly-owned subsidiary of Professional (the “Bank” and collectively with Professional, the “Company”).

Preamble

WHEREAS, the Boards of Directors of SBC and Professional have approved this Agreement and the transactions described herein and have declared the same advisable and in the best interests of each of SBC and Professional and each of SBC and Professional’s shareholders;

WHEREAS, this Agreement provides for the acquisition of Professional by SBC pursuant to the merger of Professional with and into SBC (the “Merger”) and the merger of the Bank with and into SNB (the “Bank Merger”) pursuant to the terms of the Plan of Merger and Merger Agreement between SNB and the Bank attached hereto as Exhibit A (the “Bank Merger Agreement”); and

WHEREAS, concurrently with the execution and delivery of this Agreement, as a condition and inducement to Seacoast’s willingness to enter into this Agreement, certain of (i) the Company’s directors, and (ii) the Company’s executive officers, have executed and delivered to SBC, an agreement in substantially the form of Exhibit B (the “Shareholder Support Agreement”), pursuant to which they have agreed, among other things, subject to the terms of such Shareholder Support Agreement, to vote the shares of Professional Common Stock held of record by such Persons or as to which they otherwise have sole voting power to approve and adopt this Agreement and the transactions contemplated hereby, including the Merger. Furthermore, the Company agrees to request and pursue with reasonable efforts, at SBC’s request, the execution and delivery of a Shareholder Support Agreement by any beneficial holders of five percent (5%) or more of the outstanding shares of Professional Common Stock.

Certain terms used and not otherwise defined in this Agreement are defined in Section 7.1.

NOW, THEREFORE, in consideration of the above and the mutual warranties, representations, covenants, and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally bound hereby, the Parties agree as follows:

ARTICLE 1

TRANSACTIONS AND TERMS OF MERGER

1.1 Merger. Subject to the terms and conditions of this Agreement, at the Effective Time (as defined in Section 1.4 herein), Professional shall be merged with and into SBC in accordance with the provisions of the FBCA. SBC shall be the surviving corporation (the “Surviving Corporation”) resulting from the Merger and the separate corporate existence of Professional shall thereupon cease. SBC shall continue to be governed by the Laws of the State of Florida, and the separate corporate existence of SBC with all of its rights, privileges, immunities, powers and franchises shall continue unaffected by the Merger.

1.2 Bank Merger. Prior to the Effective Time, the Boards of Directors of SNB and the Bank will execute the Bank Merger Agreement. Subject to the terms and conditions of this Agreement and the Bank Merger Agreement, immediately following the Merger, the Bank shall be merged with and into SNB in accordance with the provisions of 12 U.S.C. Section 215a and with the effect provided in 12 U.S.C. Section 215a. SNB shall be the surviving bank (the “Surviving Bank”) resulting from the Bank Merger and the separate existence of the Bank shall thereupon cease. SNB shall continue to be governed by the Laws of the United States, and the separate existence of SNB with all of its rights, privileges, immunities, powers and franchises shall continue unaffected by the Bank Merger. Subject to the satisfaction of the conditions to closing set forth in the Bank Merger Agreement, the Bank Merger shall occur immediately following the Merger unless otherwise determined by Seacoast in its discretion.

LEGAL02/41775964v16

1.3 Time and Place of Closing. Unless otherwise mutually agreed to by Seacoast and the Company, the closing of the Merger (the “Closing”) shall take place in the offices of ▇▇▇▇▇▇ & Bird LLP, One Atlantic Center, ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇ at 10:00 a.m., Atlanta time, on the date when the Effective Time is to occur (the “Closing Date”).

1.4 Effective Time. Subject to the terms and conditions of this Agreement, on the Closing Date, the Parties will cause articles of merger to be filed with the Secretary of State of the State of Florida as provided in the FBCA (the “Articles of Merger”). The Merger shall take effect when the Articles of Merger become effective (the “Effective Time”). Subject to the terms and conditions hereof, the Parties shall use their reasonable best efforts to cause the Effective Time to occur on or before February 28, 2023; provided that, if such date is not practicable, the parties shall cause the Effective Time to occur on a mutually agreeable date within ten (10) Business Days following the date on which satisfaction or waiver of the conditions set forth in Article 5 has occurred (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions).

1.5 Conversion of Professional Common Stock.

(a) At the Effective Time, in each case subject to Section 1.5(d) and excluding Dissenting Shares and subject to certain adjustments set forth in this Agreement, by virtue of the Merger and without any action on the part of the Parties or the holder thereof, each share of Professional Common Stock that is issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive, subject to the terms herein, the number of shares of SBC Common Stock equal to the Exchange Ratio (the “Merger Consideration”); provided, however, that in the event the conditions set forth in Section 5.2(j) of this Agreement are not satisfied, Seacoast shall have the option to adjust the Merger Consideration downward by an amount (the “Merger Consideration Adjustment”) calculated in accordance with Schedule 1.5(a) of the Seacoast Disclosure Letter, and waive the satisfaction of such condition set forth in Section 5.2(j). If instead of adjusting the Merger Consideration, Seacoast elects not to close the Merger transaction and terminate this Agreement in accordance with Article 6 hereof, Seacoast agrees that it will also waive any breach of Section 4.2(v). At least ten (10) days prior to the Closing Date, the Company and Seacoast shall agree on a schedule setting forth the expected Professional Consolidated Tangible Shareholders’ Equity amount as of the Closing Date. The consideration which all of the Company shareholders are entitled to receive pursuant to this Article 1 is collectively referred to herein as the “Aggregate Merger Consideration.”

(b) At the Effective Time, all shares of Professional Common Stock shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist as of the Effective Time, and each certificate or electronic book-entry previously representing any such shares of Professional Common Stock (the “Professional Certificates”) shall thereafter represent only the right to receive the Merger Consideration and any cash in lieu of fractional shares pursuant to Section 1.5(c); provided, however, that any Dissenting Shares shall thereafter represent only the right to receive applicable payments as set forth in Section 2.3.

(c) Notwithstanding any other provision of this Agreement, each holder of shares of Professional Common Stock or Professional Restricted Stock Awards exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of SBC Common Stock (after taking into account all Professional Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of SBC Common Stock multiplied by the Average Closing Price less any applicable withholding Taxes. No such holder will be entitled to dividends, voting rights, or any other rights as a shareholder in respect of any fractional shares.

(d) If, prior to the Effective Time, the issued and outstanding shares of SBC Common Stock or Professional 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, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, then an appropriate and proportionate adjustment shall be made to the Merger Consideration.

(e) Each share of Professional Common Stock issued and outstanding immediately prior to the Effective Time and owned by any of the Parties or their respective Subsidiaries (in each case other than shares of Professional Common Stock held on behalf of third parties) shall, by virtue of the Merger and without any action on the part of the holder thereof, cease to be outstanding, shall be cancelled and retired without payment of any consideration therefor and shall cease to exist (together with the Dissenting Shares, the “Excluded Shares”).

1.6 SBC Common Stock. At and after the Effective Time, each share of SBC Common Stock issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of SBC Common Stock and shall not be affected by the Merger.

1.7 Professional Equity Awards.

(a) Treatment of Professional Options. At the Effective Time, each Professional Option shall, by virtue of the Merger, automatically cease to be outstanding, and, in consideration therefor, SBC shall grant to each holder of Professional Options, as of the Effective Time, an option to purchase shares of SBC Common Stock pursuant to the SBC Incentive Plan (each, a “Substitute SBC Option”), on the same terms and conditions (including applicable exercise periods, payment methods, and expiration provisions, but excluding general administrative terms and conditions which shall be governed in accordance with the SBC Incentive Plan) as applicable to each such Professional Option as in effect immediately prior to the Effective Time, except that (A) the number of shares of SBC Common Stock subject to such Substitute SBC Option shall equal the product of (x) the number of shares of Professional Common Stock subject to such Professional Option immediately prior to the Effective Time, multiplied by (y) the Exchange Ratio, rounded down to the nearest whole share, and (B) the per share exercise price for the shares of SBC Common Stock issuable upon exercise of such Substitute SBC Option shall equal the quotient determined by dividing (x) the exercise price per share of Professional Common Stock under such Professional Option immediately prior to the Effective Time by (y) the Exchange Ratio, rounded up to the nearest whole cent; provided, however, that the exercise price and the number of shares of SBC Common Stock issuable upon exercise of such Substitute SBC Option shall be determined in a manner consistent with the requirements for a substitution of stock rights in accordance with Section 409A of the Code.

(b) Treatment of Professional Restricted Stock Awards. At the Effective Time, each share of Professional Common Stock that is subject to a Professional Restricted Stock Award that is outstanding immediately prior to the Effective Time shall, by virtue of the Merger, automatically be vested and converted into the right to receive, subject to the terms herein, the Merger Consideration pursuant to Section 1.5, subject to withholding pursuant to Section 2.1(c).

(c) Treatment of Professional Stock Appreciation Rights. Immediately prior to the Effective Time, Professional shall cause each Professional Stock Appreciation Right that is outstanding immediately prior to the Effective Time to be vested and exercised for a number of shares of Professional Common Stock determined pursuant to the terms of the applicable Stock Appreciation Right award agreement, subject to applicable withholding. At the Effective Time, each share of Professional Common Stock issuable as a result of such exercise of Professional Stock Appreciation Rights shall, by virtue of the Merger, automatically be vested and converted into the right to receive, subject to the terms herein, the Merger Consideration pursuant to Section 1.5.

(d) No Professional Equity Award shall be outstanding as of the Effective Time, and no obligations to issue Professional Equity Awards shall exist following the Effective Time. Prior to the Effective Time, the Company shall take all actions necessary (including delivering all required notices and obtaining all necessary approvals and consents) to effect the treatment of the Professional Equity Awards as provided in this Section 1.7, to terminate the Professional Stock Plans as of the Effective Time, and to cause the provisions of any other Benefit Plan providing for the issuance, transfer or grant of any capital stock of the Company or any interest in respect of any capital stock of the Company to terminate and be of no further force and effect as of the Effective Time, and the Company shall ensure that following the Effective Time no person who was, immediately prior to the Effective Time, a holder of any Professional Equity Award, a person for whom a future grant of a Professional Equity Award had been approved, or a participant in any Professional Stock Plan or other Benefit Plan, shall have any right thereunder to acquire any capital stock of SBC, SNB, or the Company, except with respect to Substitute

SBC Options, or as provided in Section 1.5 of this Agreement with respect to the Professional Common Stock which such person received or became entitled to receive in accordance with the exercise of such Professional Equity Award prior to the Effective Time.

1.8 Organizational Documents of Surviving Corporation; Directors and Officers.

(a) The Organizational Documents of SBC in effect immediately prior to the Effective Time shall be the Organizational Documents of the Surviving Corporation after the Effective Time until otherwise amended or repealed.

(b) The directors of SBC immediately prior to the Effective Time shall be the directors of the Surviving Corporation as of the Effective Time. The officers of SBC immediately prior to the Effective Time shall be the officers of the Surviving Corporation as of the Effective Time, until the earlier of their resignation or removal or otherwise ceasing to be an officer or until their respective successors are duly elected and qualified, as the case may be.

1.9 Tax Consequences. It is the intention of the Parties to this Agreement that the Merger and the Bank Merger, for federal income tax purposes, 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” for purposes of Sections 354 and 361 of the Code. The business purpose of the Merger and the Bank Merger is to combine two financial institutions to create a strong commercial banking franchise. SBC shall have the right to revise the structure of the Merger and/or the Bank Merger contemplated by this Agreement to ensure that the Merger and the Bank Merger each qualify as a “reorganization” within the meaning of Section 368(a) of the Code or to substitute an interim corporation that is wholly owned by SBC, which interim corporation may merge with and into Professional; provided, that no such revision to the structure of the Merger or the Bank Merger shall (a) result in any changes in the amount or type of the consideration that the holders of shares of Professional Common Stock are entitled to receive under this Agreement, (b) adversely affect the tax treatment of the Merger and/or the Bank Merger with respect to Professional shareholders as a result of the transactions contemplated by this Agreement, (c) reasonably be expected to materially impede or delay consummation of the Merger, or (d) require submission to or approval of Professional’s shareholders after this Agreement has been approved by Professional’s shareholders. SBC may exercise this right of revision by giving written notice to Professional in the manner provided in Section 7.9, which notice shall be in the form of an amendment to this Agreement.

ARTICLE 2

DELIVERY OF MERGER CONSIDERATION

2.1 Exchange Procedures.

(a) Delivery of Transmittal Materials. Prior to the Effective Time, SBC shall appoint an exchange agent (the “Exchange Agent”) to act as exchange agent hereunder. At or immediately prior to the Effective Time, SBC shall deposit, or cause to be deposited, with the Exchange Agent (i) SBC Common Stock issuable pursuant to Section 1.5(a) in book-entry form equal to the Aggregate Merger Consideration (excluding any fractional share consideration), and (ii) cash in immediately available funds in an amount sufficient to pay any fractional share consideration and any dividends under Section 2.1(d). As promptly as practicable after the Effective Time (and within five Business Days), the Exchange Agent shall send to each former holder of record of shares of Professional Common Stock, including holders of the Professional Equity Awards who received Professional Common Stock in accordance with the exercise of such Professional Equity Awards prior to the Effective Time, but excluding the holders, if any, of Dissenting Shares, immediately prior to the Effective Time transmittal materials for use in exchanging such holder’s Professional Certificates for the Merger Consideration (which shall specify that delivery shall be effected, and risk of loss and title to the Professional Certificates shall pass, only upon proper delivery of such Professional Certificates (or effective affidavit of loss in lieu thereof as provided in Section 2.1(e)) to the Exchange Agent).

(b) Delivery of Merger Consideration. After the Effective Time, following the surrender of a Professional Certificate to the Exchange Agent (or effective affidavit of loss in lieu thereof as provided in Section 2.1(e)) in accordance with the terms of the letter of transmittal, duly executed, the holder of such Professional Certificate shall be entitled to receive in exchange therefor the Merger

Consideration in respect of the shares of Professional Common Stock represented by its Professional Certificate or Certificates. If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name a Professional Certificate so surrendered is registered, it shall be a condition to such payment that such Professional Certificate shall be properly endorsed or otherwise be in proper form for transfer, and the Person requesting such payment shall pay to the Exchange Agent any transfer or other similar Taxes required as a result of such payment to a Person other than the registered holder of such Professional Certificate, or establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable. Payments to holders of Dissenting Shares shall be made as required by the FBCA.

(c) Payment of Taxes. The Exchange Agent (or, after the agreement with the Exchange Agent is terminated, SBC) shall be entitled to deduct and withhold from the Merger Consideration (including cash in lieu of fractional shares of SBC Common Stock) otherwise payable pursuant to this Agreement to any holder of Professional Common Stock such amounts as the Exchange Agent or SBC, as the case may be, is required to deduct and withhold under the Code or any other provision of applicable Law, with respect to the making of such payment. To the extent the amounts are so withheld by the Exchange Agent or SBC, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Professional Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or SBC, as the case may be.

(d) Return of Merger Consideration to SBC. At any time upon request by SBC, SBC shall be entitled to require the Exchange Agent to deliver to it any remaining portion of the Merger Consideration not distributed within six months following the Effective Time to holders of Professional Certificates that was deposited with the Exchange Agent (the “Exchange Fund”) (including any interest received with respect thereto and other income resulting from investments by the Exchange Agent, as directed by SBC), and holders shall be entitled to look only to SBC (subject to abandoned property, escheat or other similar laws) with respect to the Merger Consideration, any cash in lieu of fractional shares of SBC Common Stock and any dividends or other distributions with respect to SBC Common Stock payable upon due surrender of their Professional Certificates, without any interest thereon. Notwithstanding the foregoing, neither SBC nor the Exchange Agent shall be liable to any holder of a Professional Certificate for Merger Consideration (or dividends or distributions with respect thereto) or cash from the Exchange Fund in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(e) Lost Professional Certificates. In the event any Professional Certificates shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Professional Certificate(s) to be lost, stolen or destroyed and, if required by SBC or the Exchange Agent, the posting by such Person of a bond in such sum as SBC may reasonably direct as indemnity against any claim that may be made against the Company or SBC with respect to such Professional Certificate(s), the Exchange Agent will issue the Merger Consideration deliverable in respect of the shares of Professional Common Stock represented by such lost, stolen or destroyed Professional Certificates.

2.2 Rights of Former Professional Shareholders. On or before the Closing Date, the stock transfer books of Professional shall be closed as to holders of Professional Common Stock and no transfer of Professional Common Stock by any such holder shall thereafter be made or recognized. Until surrendered for exchange in accordance with the provisions of Section 2.1, each Professional Certificate (other than the Professional Certificates representing Excluded Shares) shall from and after the Effective Time represent for all purposes only the right to receive the Merger Consideration in exchange therefor and any cash in lieu of fractional shares of SBC Common Stock to be issued or paid in consideration therefor upon surrender of such certificate in accordance with Section 1.5(c), and any dividends or distributions to which such holder is entitled pursuant to this Article 2. No dividends or other distributions with respect to SBC Common Stock with a record date after the Effective Time shall be paid to the holder of any un-surrendered Professional Certificate with respect to the shares of SBC Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 1.5(c), and all such dividends, other distributions and cash in lieu of fractional shares of SBC Common Stock shall be paid by SBC to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Professional Certificate in accordance with this

Article 2. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Professional Certificate there shall be delivered to such holder (i) whole shares of SBC Common Stock, in book-entry form, in an amount equal to the Merger Consideration to which such holder is entitled pursuant to Section 1.5(a), (ii) at the time of such surrender, the amount of dividends or other distributions, if applicable, with a record date after the Effective Time theretofore paid with respect to such whole shares of SBC Common Stock, (iii) the amount of any cash payable in lieu of a fractional share of SBC Common Stock to which such holder is entitled pursuant to Section 1.5(c), and (iv) at the appropriate payment date, the amount of dividends or other distributions, if applicable, with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of SBC Common Stock. SBC shall make available to the Exchange Agent cash for these purposes, if necessary.

2.3 Dissenters’ Rights. Any Person who otherwise would be deemed a holder of Dissenting Shares (a “Dissenting Shareholder”) shall not be entitled to receive the applicable Merger Consideration (or cash in lieu of fractional shares) with respect to the Dissenting Shares unless and until such Person shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to dissent from the Merger under the provisions of Section 607.1301 through 607.1340 of the FBCA (the “Dissenter Provisions”). Each Dissenting Shareholder shall be entitled to receive only the payment provided by the Dissenter Provisions with respect to shares of Professional Common Stock owned by such Dissenting Shareholder. The Company shall give SBC (i) prompt notice of any written demands for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable Law received by the Company relating to shareholders’ rights of appraisal and (ii) the opportunity to direct all negotiations and proceedings with respect to demand for appraisal under the Dissenter Provisions. The Company shall not, except with the prior written consent of SBC, voluntarily make any payment with respect to any demands for appraisals of Dissenting Shares, offer to settle or settle any such demands or approve any withdrawal of any such demands.

ARTICLE 3

REPRESENTATIONS AND WARRANTIES

3.1 Company Disclosure Letter. Prior to the execution and delivery of this Agreement, the Company has delivered to Seacoast a letter (the “Company Disclosure Letter”) setting forth, among other things, items the disclosure of which is necessary or appropriate either in response to an express disclosure requirement contained in a provision hereof or as an exception to one or more of the Company’s representations or warranties contained in this Article 3 or to one or more of its covenants contained in Article 4; provided, that (a) no such item is required to be set forth in the Company Disclosure Letter as an exception to any representation or warranty of the Company if its absence would not result in the related representation or warranty being deemed untrue or incorrect under the standard established by Section 3.2, and (b) the mere inclusion of an item in the Company Disclosure Letter as an exception to a representation or warranty shall not be deemed an admission by the Company 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 with respect to the Company. Any disclosures made with respect to a subsection of Section 3.3 shall be deemed to qualify any subsections of Section 3.3 that contains sufficient detail to enable a reasonable Person to recognize the relevance of such disclosure to such other subsections. All representations and warranties of SBC and Professional shall be qualified by reference to their respective SEC Reports and such disclosures in any such SEC Reports or other publicly available documents filed with or furnished by them to the SEC or any other Governmental Authority prior to the date hereof (but excluding any risk factor disclosures contained under the heading “Risk Factors”, any disclosure of risks included in any “forward-looking statements” disclaimer or any other statements that are similarly forward-looking in nature).

3.2 Standards.

(a) No representation or warranty of any Party hereto contained in this Article 3 (other than the representations and warranties in (i) Section 3.3(c) and 3.4(c), which shall be true and correct in all respects (except for inaccuracies that are de minimis in amount), and (ii) Sections 3.3(b)(i), 3.3(b)(ii), 3.3(d) and 3.4(b)(i), which shall be true and correct in all material respects) shall be deemed untrue or incorrect, and no Party shall be deemed to have breached any of its representations or warranties, as a consequence of the existence or absence of any fact, circumstance or event unless such

fact, circumstance or event, individually or taken together in the aggregate with all other facts, circumstances or events inconsistent with such Party’s representations or warranties contained in this Article 3, has had or is reasonably likely to have a Material Adverse Effect on such Party; provided, that, for purposes of Sections 5.2(a) and 5.3(a) only, the representations and warranties which are qualified by references to “material,” “Material Adverse Effect” or to the “Knowledge” of any Party shall be deemed not to include such qualifications.

(b) Unless the context indicates specifically to the contrary, a “Material Adverse Effect” on a Party shall mean any change, event, development, violation, inaccuracy or circumstance the effect, individually or in the aggregate, of which is or is reasonably likely to have, (i) a material adverse impact on the condition (financial or otherwise), property, business, assets (tangible or intangible) or results of operations or prospects of such Party taken as a whole or (ii) prevents or materially impairs, or would be reasonably likely to prevent or materially impair, the ability of such Party to perform its obligations under this Agreement or to timely consummate the Merger, the Bank Merger or the other transactions contemplated by this Agreement; provided, however, that “Material Adverse Effect” shall not be deemed to include (A) the impact of actions and omissions of a Party (or any of its Subsidiaries) taken with the prior written consent of the other Party in contemplation of the transactions contemplated hereby, (B) changes after the date of this Agreement in GAAP or regulatory accounting requirements generally applicable to banks and their holding companies, (C) changes after the date of this Agreement in laws, rules or regulations or interpretations of laws, rules or regulations by Governmental Authorities of general applicability to banks and their holding companies and (D) changes after the date of this Agreement in general economic or market conditions in the United States or any state or territory thereof, in each case generally affecting banks and their holding companies, except to the extent with respect to clauses (B), (C) or (D) that the effect of such changes are disproportionately adverse to the condition (financial or otherwise), property, business, assets (tangible or intangible), liabilities or results of operations of such Party and its Subsidiaries taken as a whole, as compared to other banks and their holding companies. Similarly, unless the context indicates specifically to the contrary, a “Material Adverse Change” is an event, change or occurrence resulting in a Material Adverse Effect on such Party and its Subsidiaries, taken as a whole.

3.3 Representations and Warranties of the Company. Subject to and giving effect to Sections 3.1 and 3.2 and except as set forth in the Company Disclosure Letter, Professional and the Bank, jointly and severally, hereby represent and warrant to Seacoast as follows:

(a) Organization, Standing, and Power. Each Subsidiary of Professional and Bank is listed on Section 3.3(a) of the Company Disclosure Letter. Professional and each of its Subsidiaries are duly organized, validly existing, and are in good standing under the Laws of the jurisdiction of its formation. Professional and each of its Subsidiaries have the requisite corporate power and authority to own, lease, and operate their properties and assets and to carry on their businesses as now conducted. Professional and each of its Subsidiaries are duly qualified or licensed to do business and in good standing in the States of the United States and foreign jurisdictions where the character of their assets or the nature or conduct of their business requires them to be so qualified or licensed. Professional is a bank holding company within the meaning of the BHC Act and has elected to be a treated as a financial holding company under the BHC Act. The Bank is a Florida state-chartered bank and member of the Federal Reserve System. The Bank is an “insured depository institution” as defined in the Federal Deposit Insurance Act and applicable regulations thereunder, its deposits are insured by the Deposit Insurance Fund and all premiums and assessments required to be paid in connection therewith have been paid when due. No action for the revocation or termination of such deposit insurance is pending, or to the Knowledge of Professional, threatened.

(b) Authority; No Breach of Agreement.

(i) Professional and the Bank each has the corporate power and authority necessary to execute, deliver, and perform its obligations under this Agreement and to consummate the transactions contemplated hereby. The execution, delivery, and performance of this Agreement, and the consummation of the transactions contemplated hereby, have been duly and validly authorized by all necessary corporate action (including valid authorization and adoption of this Agreement by its duly constituted Board of Directors and, in the case of the Bank, its sole shareholder), subject only to the Professional Shareholder Approval and such

No attorney representing Professional or any Subsidiary, whether or not employed by Professional or any Subsidiary, has reported evidence of a material violation (as such term is interpreted under Section 307 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002, as amended, and the rules and regulations promulgated thereunder (the “▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act”)) of securities laws, breach of fiduciary duty or similar violations by Professional or any Subsidiary or any officers, directors, employees or agents of Professional or any of its Subsidiaries or any committee thereof or to any director or officer of Professional.

SNB is a national banking association domiciled in the State of Florida. SNB is an “insured institution” as defined in the Federal Deposit Insurance Act and applicable regulations thereunder, and its deposits are insured by the Deposit Insurance Fund and all premiums and assessments required to be paid in connection therewith have been paid when due.

4.12 Acquisition Proposals.

(a) Professional agrees that it will not, and will cause its directors, officers, employees and Representatives and Affiliates not to, (i) initiate, solicit, or knowingly encourage or facilitate inquiries or proposals with respect to, (ii) engage or participate in any negotiations concerning, or (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any Person relating to, any Acquisition Proposal; provided, that, in the event Professional receives an unsolicited bona fide Acquisition Proposal that does not violate (i) and (ii) above at any time prior to, but not after, the time this Agreement is adopted by the Professional Shareholder

Approval, and Professional’s Board of Directors concludes in good faith that there is a reasonable likelihood that such Acquisition Proposal constitutes or is reasonably likely to result in a Superior Proposal, Professional may, and may permit its officers and Representatives to, furnish or cause to be furnished nonpublic information or data and participate in such negotiations or discussions to the extent that the Board of Directors of Professional concludes in good faith (and based on the written advice of outside legal counsel) that failure to take such actions would reasonably be expected to result in a breach of its fiduciary obligations to the Professional Shareholders under applicable Law; provided further, that prior to providing any nonpublic information permitted to be provided pursuant to the foregoing proviso, Professional shall have entered into a confidentiality agreement with such third party on terms no less favorable to it than the Confidentiality Agreement. Professional will immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than Seacoast with respect to any Acquisition Proposal. Professional shall promptly (and in any event within two Business Days) advise Seacoast following the receipt or notice of any Acquisition Proposal and the substance thereof (including the identity of the Person making such Acquisition Proposal), and will keep Seacoast apprised of any related developments, discussions and negotiations on a current basis.

(b) Notwithstanding the foregoing, if Professional’s Board of Directors concludes in good faith (and based upon the written advice of its outside counsel and after consultation with its financial advisor and outside legal counsel) that an Acquisition Proposal constitutes or would reasonably be expected to constitute a Superior Proposal and that failure to accept such Superior Proposal would reasonably be expected to result in a breach of its fiduciary obligations under applicable Laws, Professional’s Board of Directors may at any time prior to the Professional Shareholder Approval (i) withdraw or modify (a “Change in Recommendation”) the Professional Directors’ Recommendation or make or cause to be made any third party or public communication proposing or announcing an intention to withdraw or modify the Professional Directors’ Recommendation, and (ii) terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal; provided, however, that the Board of Directors of Professional may not make a Change in Recommendation, and terminate this Agreement, with respect to an Acquisition Proposal unless (i) Professional shall not have breached this Section 4.12 in any respect and (ii) (A) the Board of Directors of Professional determines in good faith (after consultation with outside legal counsel and its financial advisors) that such Superior Proposal has been made and has not been withdrawn and continues or is reasonably expected to continue to be a Superior Proposal after taking into account all adjustments to the terms of this Agreement that may be offered by SBC under this Section 4.12(b); (B) Professional has given SBC at least four (4) Business Days’ prior written notice of its intention to take such actions set forth above (which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the Person making such Superior Proposal)) and has contemporaneously provided an unredacted copy of the relevant proposed transaction agreements with the Person making such Superior Proposal; and (C) before effecting such Change in Recommendation, Professional has negotiated, and has caused its representatives to negotiate in good faith with SBC during such notice period to the extent SBC wishes to negotiate, to enable SBC to revise the terms of this Agreement such that it would cause such Superior Proposal to no longer constitute a Superior Proposal. In the event of any material change to the terms of such Superior Proposal, Professional shall, in each case, be required to deliver to SBC a new written notice, the notice period shall have recommenced and Professional shall be required to comply with its obligations under this Section 4.12 with respect to such new written notice. Professional will advise SBC in writing within twenty-four (24) hours following the receipt of any Acquisition Proposal and the substance thereof (including the identity of the Person making such Acquisition Proposal) and will keep SBC apprised of any related developments, discussions and negotiations (including the terms and conditions of the Acquisition Proposal) on a current basis.

4.13 Takeover Laws. If any Takeover Law may become, or may purport to be, applicable to the transactions contemplated hereby, Professional and the members of its Board of Directors will grant such approvals and take such actions as are necessary (other than any action requiring the approval of its shareholders (other than as contemplated by Section 4.5)) so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Law on any of the transactions contemplated by this Agreement.

4.14 Employee Benefits and Contracts.

(a)Following the Effective Time, SBC shall maintain or cause to be maintained employee benefit plans and compensation opportunities for the benefit of employees (as a group) who are full-time active employees of Professional and/or its subsidiaries on the Closing Date (“Covered Employees”) that provide employee benefits and compensation opportunities which, in the aggregate, are substantially comparable to the employee benefits and compensation opportunities that are made available on a uniform and non-discriminatory basis to similarly situated employees of SBC or its Subsidiaries, as applicable; provided, however, that in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of SBC or its Subsidiaries; and provided further that in no event shall SBC be required to take into account any retention arrangements or equity compensation when determining whether employee benefits are substantially comparable. SBC shall give the Covered Employees full credit for their prior service with Professional and its Subsidiaries (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 SBC and in which Covered Employees may be eligible to participate and (ii) for all purposes under any welfare benefit plans, vacation plans and similar arrangements maintained by SBC.

(b)With respect to any employee benefit plan of SBC 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, SBC or its applicable Subsidiary shall use its commercially reasonable best efforts to (i) cause any pre-existing condition limitations or eligibility waiting periods under such SBC or Subsidiary plan to be waived with respect to such Covered Employee to the extent such condition was or would have been covered under the Professional 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 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 deductible and annual out-of-pocket expense requirements under any such health, dental, vision or other welfare plan.

(c)Prior to the Effective Time, Professional shall take all actions requested by SBC that may be necessary or appropriate to (i) cause Professional’s 401(k) Plan, and one or more of the Professional Benefits Plans 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 Professional 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 Professional Benefit Plan for such period as may be requested by SBC, or (iv) facilitate the merger of any Professional Benefit Plan into any employee benefit plan maintained by SBC or an SBC Subsidiary. All resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this Section 4.14(c) shall be subject to SBC’s reasonable prior review and approval, which shall not be unreasonably withheld, conditioned, or delayed.

(d)Nothing in this Section 4.14 shall be construed to limit the right of SBC or any of its Subsidiaries (including, following the Closing Date, Professional) to amend or terminate any Professional Benefit Plan or other 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 4.14 be construed to require SBC or any of its Subsidiaries (including, following the Closing Date, Professional) 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 SBC or any of its Subsidiaries of any Covered Employee subsequent to the Effective Time shall be subject in all events to SBC’s or its applicable Subsidiary’s normal and customary employment procedures and practices, including customary background screening and evaluation procedures, and satisfactory employment performance.

(e)If, within six (6) months after the Effective Time, any Covered Employee (other than those Covered Employees who receive change in control benefits or retention benefits pursuant to employment or retention agreements with Professional), is terminated by SBC or its Subsidiaries other than (i) “for cause” or (ii) as a result of death, disability or unsatisfactory job performance, then SBC shall pay severance to such Covered Employee in an amount as set forth in the severance policies set forth in

Section 4.14(e)(i) of the Seacoast Disclosure Letter (and based upon the non-exempt and exempt status and/or title for the Covered Employee with Professional at the Closing). Any severance to which a Covered Employee may be entitled in connection with a termination occurring more than six (6) months after the Effective Time will be as set forth in the severance policies set forth in Section 4.14(e)(ii) of the Seacoast Disclosure Letter.

(f)At or before the Closing, Professional shall make the payments set forth on Section 4.14(f) of the Company Disclosure Letter.

4.15 Indemnification.

(a) From and after the Effective Time, in the event of any threatened or actual claim, action, suit, proceeding, or investigation, whether civil, criminal, or administrative, in which any Person who is now, or has been at any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director or officer of Professional or any of its Subsidiaries (each an “Indemnified Party”) is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that the Indemnified Party is or was a director, officer, or employee of Professional, its Subsidiaries or any of its predecessors, or (ii) this Agreement or any of the transactions contemplated hereby, whether in any case asserted or arising before or after the Effective Time, Seacoast shall indemnify, defend and hold harmless to the same extent such Indemnified Parties have the right to be indemnified and/or have the right to advancement of expenses pursuant to (x) the Organizational Documents of Professional or such Subsidiary, as applicable and (y) the FBCA or other applicable Law, each such Indemnified Party against any Liability (including advancement of reasonable attorneys’ fees and expenses prior to the final disposition of any claim, suit, proceeding, or investigation to each Indemnified Party to the fullest extent permitted by Law upon receipt of any undertaking required by applicable Law), judgments, fines, and amounts paid in settlement in connection with any such threatened or actual claim, action, suit, proceeding, or investigation. In the event of any such threatened or actual claim, action, suit, proceeding, or investigation (whether asserted or arising before or after the Effective Time), the Indemnified Parties may retain counsel reasonably satisfactory to them; provided, that (1) Seacoast shall have the right to assume the defense thereof and upon such assumption Seacoast shall not be required to advance to any Indemnified Party any legal expenses of other counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if Seacoast elects not to assume such defense or counsel for the Indemnified Parties reasonably advises the Indemnified Parties that there are material issues that raise conflicts of interest between Seacoast and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to them, and Seacoast shall advance the reasonable fees and expenses of such counsel for the Indemnified Parties, (2) Seacoast shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld), and (3) Seacoast shall have no further obligation hereunder to any Indemnified Party when and if a court of competent jurisdiction shall determine, and such determination shall have become final, that indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable Law.

(b) Seacoast agrees that all existing rights to indemnification and all existing limitations on Liability existing in favor of the directors, officers, and employees of Professional and the Bank as provided in their respective Organizational Documents as in effect as of the date of this Agreement shall survive the Merger and shall continue in full force and effect, and shall be honored by such entities or their respective successors as if they were the indemnifying party thereunder, without any amendment thereto; provided, that nothing contained in this Section 4.15(b) shall be deemed to preclude the liquidation, consolidation, or merger of SBC or SNB, in which case all of such rights to indemnification and limitations on Liability shall be deemed to so survive and continue notwithstanding any such liquidation, consolidation or merger. Without limiting the foregoing, in any case in which approval by Seacoast is required to effectuate any indemnification for any director or officer of Professional or the Bank, Seacoast shall direct, at the election of the Indemnified Party that the determination of any such approval shall be made by independent counsel mutually agreed upon between Seacoast and the Indemnified Party.

(c) Seacoast, from and after the Effective Time, will directly or indirectly cause the Persons who served as directors or officers of Professional or the Bank at or before the Effective Time to

be covered by Professional’s existing directors’ and officers’ liability insurance policy; provided, that Seacoast may substitute therefor policies of at least the same coverage and amounts containing terms and conditions that are not less advantageous than such policy; provided further, that in no event shall the aggregate premiums applicable to such coverage exceed 150% of the current annual premium paid by Professional (such amount, as set forth on Section 4.15(c) of the Company Disclosure Letter) for such insurance. Such insurance coverage shall commence at the Effective Time and will be provided for a period of no less than six (6) years after the Effective Time.

(d) If SBC or SNB or any of their respective successors or assigns shall consolidate with or merge into any other Person and shall not be the continuing or surviving Person of such consolidation or merger or shall transfer all or substantially all of its assets to any Person, then and in each case, proper provision shall be made so that the successors and assigns of SBC or SNB, as applicable, as the surviving entities shall assume the obligations set forth in this Section 4.15.

(e) The provisions of this Section 4.15 are intended to be for the benefit of and shall be enforceable by, each Indemnified Party and his or her heirs and representatives.

Professional shall coordinate and participate in regular meetings between data processing vendors and Seacoast representatives, to begin within 30 days following the date of this agreement, to facilitate system integration. Professional shall cooperate with Seacoast in connection with the planning for the efficient and orderly combination of the parties and the operation of SNB (including the former operations of Professional) after the Merger and the Bank Merger, and in preparing for the consolidation of appropriate operating functions to be effective at the Effective Time or such later date as Seacoast may decide. Prior to the Effective Time, Professional shall take any action that Seacoast may reasonably request to facilitate the combination of the operations of the Bank with SNB and Professional shall allocate and apply resources and personnel with appropriate expertise and authority to effectuate such requests. Without limiting the foregoing, Professional shall provide office space and support services (and other reasonably requested support and assistance) in connection with the foregoing, and senior officers of Professional and Seacoast shall meet from time to time as Professional or Seacoast may reasonably request, to review the financial and operational affairs of Professional and its Subsidiaries, and Professional shall give due consideration to Seacoast’s input on

Professional shall be responsible for all conversion and deconversion fees and expenses, regardless of whether the Merger becomes effective.

The Professional shareholders will timely file or cause to be timely filed all necessary documentation and Tax Returns with respect to Transfer Taxes, and Seacoast will assist in such filing as may be required by applicable Law. Each Party will each use its commercially reasonable efforts to avail itself of any available exemptions from any such Transfer Taxes.

Consummation by the Shareholder of the transactions contemplated hereby will not violate, or require any consent, approval, or notice under, any provision of any judgment, order, decree, statute, law, rule or regulation applicable to the Shareholder or the Shareholder’s Shares.

(iv)The Shareholder’s Shares and any certificates representing the Shareholder’s Shares are now, and at all times during the term hereof will be, held by the Shareholder, or by a nominee or custodian for the benefit of such Shareholder, free and clear of all pledges, liens, security interests, claims, proxies, voting trusts or agreements, understandings or arrangements or any other encumbrances whatsoever (any such encumbrance, a “Lien”), except for (i) any such

EXHIBIT B

Liens arising hereunder, and (ii) Liens, if any, which have been previously disclosed in writing to Buyer and will be satisfied and released at Closing.

(v)The Shareholder understands and acknowledges that Buyer entered into the Merger Agreement in reliance upon the Shareholder’s execution and delivery of this Agreement.

(b.Voting Agreements. The Shareholder agrees with, and covenants to, Buyer as follows:

(viii)At any meeting of shareholders of Seller called to vote upon the Merger Agreement, the Merger and the Transactions, and at any adjournment or postponement thereof, or in any other circumstances upon which a vote, consent or other approval with respect to the Merger Agreement, the Merger and the Transactions is sought (collectively, the “Shareholders’ Meeting”), the Shareholder shall vote (or cause to be voted) all of the Shareholder’s Shares in favor of the approval of the terms of the Merger Agreement, the Merger and each of the Transactions, and shall not grant any proxies to any third party, except where such proxies are expressly directed to vote in favor of the Merger Agreement, the Merger and the Transactions. The Shareholder hereby waives all notice and publication of notice of any Shareholders’ Meeting to be called or held with respect to the Merger Agreement, the Merger and the Transactions.

(ix)At any Shareholders’ Meeting or in any other circumstances upon which a Seller shareholder vote, consent or other approval is sought, the Shareholder shall vote (or cause to be voted) such Shareholder’s Shares against (i) any acquisition proposal, including, without limitation, any merger or exchange agreement or merger or exchange (other than the Merger Agreement, the Merger and the Transactions), consolidation, combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of or by Seller; (ii) any action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of Seller contained in the Merger Agreement or of Shareholder contained in this Agreement; and (iii) any amendment of Seller’s articles of incorporation or bylaws or other proposal or transaction involving Seller or any of its Subsidiaries, which amendment or other proposal or transaction would in any manner delay, impede, frustrate, prevent or nullify the Merger Agreement, or any of the Transactions, other than an amendment or other proposal or transaction required by a regulatory authority or other Governmental Authority (each of the foregoing in clauses (i), (ii) or (iii) above, a “Competing Transaction”).

(c.Covenants. The Shareholder agrees with, and covenants to, Buyer as follows:

EXHIBIT B

(x)Without the prior written consent of Buyer, the Shareholder shall not (i) “Transfer” (which term shall include, without limitation, for the purposes of this Agreement, any sale, gift, pledge, transfer, hypothecation or other disposition), or consent to any Transfer of, any or all of the Shareholder’s Shares or any interest therein, (ii) enter into any contract, option or other agreement, arrangement or understanding with respect to any Transfer of any or all of Shareholder’s Shares or any interest therein, (iii) grant or solicit any proxy, power of attorney or other authorization in or with respect to Shareholder’s Shares, except for this Agreement, (iv) deposit Shareholder’s Shares into a voting trust or enter into any voting agreement, arrangement or understanding with respect to Shareholder’s Shares for any purpose (other than to satisfy its obligations under this Agreement), or (v) initiate a shareholders’ vote or action by consent of Seller’s shareholders with respect to a Competing Transaction; provided, however, that the foregoing shall not preclude a Transfer in connection with bona fide estate planning purposes to the Shareholder’s affiliates or immediate family members, provided that as a condition to such Transfer, such affiliate or immediate family member shall execute an agreement that is identical to this Agreement (except to reflect the change in the ownership of the Shareholder’s Shares) and provided further, that the assigning Shareholder shall remain jointly and severally liable for any breaches by any of his or her affiliates or immediate family members of the terms hereof. The restriction on the Transfer of the Shareholder’s Shares set forth in this Section 3(a) shall terminate upon the first to occur of (x) the Effective Time of the Merger and the Transactions or (y) the date upon which the Merger Agreement is terminated in accordance with its terms.

(xi)The Shareholder hereby waives any rights of appraisal, or rights to dissent from the Merger or the Transactions that such Shareholder may have.

(xii)The Shareholder shall not, nor shall it permit any investment banker, attorney or other adviser or representative of the Shareholder to, directly or indirectly, (i) solicit, initiate, knowingly induce or encourage, or knowingly take an action to facilitate the making of the submission of any Competing Transaction, or (ii) except as provided in the Merger Agreement, participate in any discussions or negotiations regarding, or furnish to any person any information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes, or may reasonably be expected to lead to, any Competing Transactions, other than the Merger or the Transactions contemplated by the Merger Agreement.

4.Irrevocable Proxy. Subject to the last sentence of this Section 4, by execution of this Agreement, Shareholder does hereby appoint Buyer with the full power of substitution and resubstitution, as Shareholder’s true and lawful attorney and irrevocable proxy, to the full extent of Shareholder’s rights with respect to Shareholder’s Shares, to vote each of such Shareholder Shares that Shareholder shall be entitled to so vote with respect to the matters set forth in Section 2 hereof at any Shareholders’ Meeting, and at any adjournment or postponement thereof, and in connection with any action of the shareholders of Seller taken by written consent. Shareholder intends this proxy to be irrevocable and coupled with an interest hereafter until the termination of this Agreement pursuant to the terms of Section 9 hereof and hereby revokes any proxy previously granted by Shareholder with respect to the Shareholder Shares. Notwithstanding anything contained herein to the contrary, this irrevocable proxy shall automatically terminate upon the termination of this Agreement.

5.Certain Events. The Shareholder agrees that this Agreement and the obligations hereunder shall attach to the Shareholder’s Shares and shall be binding upon any person or entity to which legal or beneficial ownership of Shareholder’s Shares shall pass, whether by operation of law or otherwise, including the Shareholder’s successors or assigns. In the event of any stock split, stock dividend, merger, exchange, reorganization, recapitalization or other change in the capital structure of the Seller affecting the Seller Common Stock, or the acquisition of additional shares of Seller Stock or other voting securities of Seller by Shareholder, the number of shares of Seller Stock subject to the terms of this

EXHIBIT B

Agreement shall be adjusted appropriately and this Agreement and the obligations hereunder shall attach to any additional shares of Seller Stock or other voting securities of the Seller issued to or acquired by the Shareholder.

6.Specific Performance; Remedies; Attorneys’ Fees. Shareholder acknowledges that it is a condition to the willingness of Buyer 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 Buyer if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, irreparable damage will occur and Buyer will not have any adequate remedy at law. It is accordingly agreed that Buyer shall be entitled to seek specific performance and injunctive or other equitable relief as a remedy for any such breach or to prevent any breach and to enforce specifically the terms and provisions of this Agreement, in addition to any other remedy to which they are entitled at law or in equity. Seller agrees that it shall not oppose the granting of such relief on the basis that Buyer has an adequate remedy at law. In addition, any third party participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement and of the rights of Buyer hereunder, and any such participation by such third party with Shareholder in activities in violation of the Shareholder’s agreement with Buyer set forth in this Agreement may give rise to claims by Buyer against such third party and Buyer acknowledges that Shareholder may be responsible for any associated liabilities caused by such third party. In any legal action or other proceeding relating to this Agreement and the transactions contemplated hereby or if the enforcement of any provision of this Agreement is brought against either Party, the prevailing Party in such action or proceeding shall be entitled to recover all reasonable expenses relating thereto (including reasonable attorneys’ fees and expenses, court costs and expenses incident to arbitration, appellate and post-judgment proceedings) from the other Party, in addition to any other relief to which such prevailing Party may be entitled.

7.Further Assurances. The Shareholder shall, upon the request of the Buyer, promptly execute and deliver any additional documents and take such further actions as may reasonably be deemed by the Buyer to be necessary or desirable to carry out the provisions hereof and to vest in the Buyer the power to vote such Shareholder’s Shares as contemplated by Section 2 and 4 of this Agreement and the other irrevocable proxies provided herein.

8.Confidentiality. The undersigned recognizes and acknowledges that he or she may have access to certain confidential information of the Buyer and its subsidiaries (including that obtained from the Seller and its shareholders in connection with the Transactions), the Seller and its Subsidiaries and their shareholders, including, without limitation, customer lists, information regarding customers, confidential methods of operation, lending, credit information, organization, product/service formulas, pricing, ▇▇▇▇-ups, commissions, information concerning techniques for use and integration of websites and other products/services, current and future development and expansion or contraction plans, sale/acquisition plans and contacts, marketing plans and contacts, information concerning the legal affairs of and information concerning the pricing of products and services, strategy, tactics and financial affairs and other information and that all such information constitutes valuable, special and unique property of the Buyer, the Seller and the Buyer’s shareholders. All such information, which shall exclude any information that is publicly known or hereafter becomes publicly known other than as a result of any action or omission by the undersigned, is herein referred to as “Confidential Information.” The undersigned will not disclose or directly or indirectly utilize in any manner any such Confidential Information for Shareholder’s own benefit or the benefit of anyone other than the Buyer and/or its shareholders during the term of this Agreement and for a period of two (2) years after the termination of this Agreement pursuant to Section 9; provided that the undersigned may disclose such Confidential Information as required by law, court order or other valid and appropriate legal process.

9.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

EXHIBIT B

contemplated by the Merger Agreement by the written consent of the parties hereto, and this Agreement shall be automatically terminated upon either (i) the termination of the Merger Agreement in accordance with its terms, or (ii) the consummation of the Merger. 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; provided further that the provisions of Section 8 of this Agreement shall remain in full force and effect regardless of any such termination pursuant to this Section 9.

10.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 reasonable best efforts to substitute a valid, legal and enforceable provision which, insofar as practical, implements the purpose and intents of this Agreement.

11.Miscellaneous.

(xiii)Capitalized terms used and not otherwise defined in this Agreement shall have the respective meanings assigned to them in the Merger Agreement. As used herein, the singular shall include the plural and any reference to gender shall include all other genders. The terms “include,” “including” and similar phrases shall mean including without limitation, whether by enumeration or otherwise.

Signatures of the parties transmitted by facsimile or electronic transmission shall be deemed to be their original signatures for all purposes.

(xvii)This Agreement (including the documents and instruments referred to herein) constitutes the entire agreement and understanding of the parties with respect to the subject matter hereof, and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof.

(xviii)This Agreement shall be governed by and construed and interpreted in accordance with the laws of the State of Florida without regard to the applicable conflicts of laws principles thereof.

(xix)If any term, provision, covenant or restriction herein, or the application thereof to any circumstance, shall, to any extent, be held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions herein

EXHIBIT B

2. Restrictive Covenants.

From the Effective Time and thereafter for so long as such information remains Confidential Information, Employee shall not directly or indirectly transmit or disclose any Confidential Information to any Person, or use or permit others to use any such Confidential Information, directly or indirectly, for any purpose, without the prior express written consent of the Chief Executive Officer of Buyer, which consent may be withheld in the sole discretion of Buyer’s Chief Executive Officer. Anything herein to the contrary notwithstanding, Employee shall not be restricted from disclosing information that is required to be disclosed by law, court order or other valid and appropriate legal process; provided, however, that in the event such disclosure is required by law, Employee shall (i) if allowed by law or legal process, provide Buyer with prompt notice of such requirement so that Buyer may seek an appropriate protective order prior to any such required disclosure by Employee; and (ii) use commercially reasonable efforts to obtain assurances that any Confidential Information disclosed will be accorded confidential treatment; provided, further, that no such notice or efforts shall be required in connection with any routine audit or investigation by any Governmental Authority or taxing authority that does not expressly reference Seller, Buyer, SNB or any of their respective Affiliated Companies.

It is acknowledged that general advertisements shall not be deemed to violate this provision.

For purposes of this Agreement, “Compete” means to engage or participate in Business Activities (or to prepare to engage or participate in Business Activities) on Employee’s own behalf, or with, for, or on behalf of (i) any other financial institution as an officer, director, manager, owner, partner, joint venture, consultant, independent contractor, employee, or shareholder of, or (ii) any other Person, business, or enterprise. For purposes of this Agreement, “Business Activities” shall be any business activities conducted by Buyer, Seller, SNB, or any of their Affiliated Companies, which includes commercial or consumer loans and extensions of credit, letters of credit, commercial and consumer deposits and deposit accounts, securities repurchase agreements and sweep accounts, cash management services, money transfer and ▇▇▇▇ payment services, internet or electronic banking, automated teller machines, ▇▇▇ and retirement accounts, commercial or consumer mortgage loans, and commercial or consumer home equity lines of credit. For purposes of this Agreement, the “Restricted Area” means each and any county where the Buyer, SNB, Bank or any of their Affiliated Companies (i) operates a banking office, or (ii) has operated a banking office within the preceding 12 months, or (iii) is actively engaged in providing Business Activities to customers. Nothing in this Section 2(d) shall prohibit Employee from acquiring or holding, for investment purposes only, less than five percent (5%) of the outstanding securities of any company or business organization which may compete directly or indirectly with Seller, Buyer, SNB or any of their Affiliated Companies. Nothing in this Agreement shall prohibit Employee or any of such Employee’s Affiliated Companies from continuing to hold outstanding securities of an entity that engages in Business Activities; provided that, such securities were held by the Employee or any of such Employee’s Affiliated Company as of the date of this Agreement.

EXHIBIT D-1

(e) Enforceability of Covenants. Employee acknowledges and agrees that the covenants in this Agreement are direct consideration for a sale of a business and should be governed by standards applicable to restrictive covenants entered into in connection with a sale of a business. Employee acknowledges that each of Buyer, SNB and its Affiliated Companies have a current and future expectation of business within the Restricted Area and from the current and proposed customers of Seller that are derived from the acquisition of Seller by Buyer. Employee acknowledges that the term, geographic area, and scope of the covenants set forth in this Agreement are reasonable, and agrees that he will not, in any action, suit or other proceeding, deny the reasonableness of, or assert the unreasonableness of, the premises, consideration or scope of the covenants set forth herein. Employee agrees that his position as an Employee of Professional and/or the Bank involves duties and authority relating to all aspects of the Business Activities and all of the Restricted Area. Employee further acknowledges that complying with the provisions contained in this Agreement will not preclude him from engaging in a lawful profession, trade or business, or from becoming gainfully employed. Employee and Buyer agree that Employee’s obligations under the above covenants are separate and distinct under this Agreement, and the failure or alleged failure of the Buyer to perform its obligations under any other provision of this Agreement shall not constitute a defense to the enforceability of this covenant. Employee and Buyer agree that if any portion of the foregoing provisions is deemed to be unenforceable because the geography, time or scope of activities restricted is deemed to be too broad, the court shall be authorized to substitute for the overbroad term an enforceable term that will enable the enforcement of the covenants to the maximum extent possible under applicable law. Employee acknowledges and agrees that any breach or threatened breach of this covenant will result in irreparable damage and injury to the Buyer, SNB and their Affiliated Companies and that damages arising out of such breach would be difficult to ascertain. Employee hereby agrees that, in addition to all other remedies provided at law or in equity, Buyer will be entitled to exercise all rights including, without limitation, obtaining one or more temporary restraining orders, injunctive relief and other equitable relief, including specific performance in the event of any breach or threatened breach of this Agreement, without the necessity of posting any bond or security (all of which are waived by the Employee), and to exercise all other rights or remedies, at law or in equity, including, without limitation, the rights to damages.

3. Successors.

(a) This Agreement is personal to Employee, is not assignable by Employee, and none of Employee’s duties hereunder may be delegated.

(b) This Agreement may be assigned by, and shall be binding upon and inure to the benefit of the Buyer, SNB and any of their Affiliated Companies and their successors and assigns.

4. Miscellaneous.

(i)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 Employee and Buyer. 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.

remaining provisions or covenants, or any part thereof, of this Agreement, all of which shall remain in full force and effect.

Buyer and Employee agree that this Agreement shall be governed by and construed and interpreted in accordance with the laws of the State of Florida without giving effect to its conflicts of law principles, and that any and all disputes arising out of or relating to this Agreement shall be brought and exclusively maintained in the 19th Circuit Court in and for ▇▇▇▇▇▇ County, Florida, Stuart Division.
