This Agreement and Plan of Merger (this “Agreement”) is dated as of the 17^th day of October, 2016, by and between CenterState Banks, Inc., a Florida corporation (“CenterState”), and Platinum Bank Holding Company a Florida corporation (“PBHC” and, together with CenterState, the “Parties” and each a “Party”).

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 PBHC will, on the terms and subject to the conditions set forth in this Agreement, merge with and into CenterState (the “Merger”), with CenterState as the surviving company in the Merger (sometimes referred to in such capacity as the “Surviving Company”);

WHEREAS, as a condition to the willingness of CenterState to enter into this Agreement, all of the directors of PBHC have entered into voting agreements (each a “Voting Agreement”), substantially in the form attached hereto as Exhibit A, dated as of the date hereof, with CenterState, pursuant to which each such director has agreed, among other things, to vote all of the PBHC 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 Voting Agreement; and

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;

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained in this Agreement, the Parties agree as follows:

1.1The Merger. Subject to the terms and conditions of this Agreement, in accordance with the Florida Business Corporation Act (the “FBCA”), at the Effective Time, PBHC shall merge with and into CenterState. CenterState shall be the Surviving Company in the Merger and shall continue its existence as a corporation under the laws of the State of Florida. As of the Effective Time, the separate corporate existence of PBHC shall cease.

1.2Effective Time. Subject to the terms and conditions of this Agreement, simultaneously with the Closing, the Parties shall execute, and CenterState shall cause to be filed with the Department of State of the State of Florida and the Secretary of State of the State of Florida, articles of merger as provided in the FBCA (the “Articles of Merger”). The Merger shall become effective at such time as the Articles of Merger are filed or such other time as may be specified in such Articles of Merger (the “Effective Time”); provided, however, that the Effective Time shall occur no earlier than April 1, 2017.

1.3Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in the FBCA.

1.4Conversion of Stock. By virtue of the Merger and without any action on the part of PBHC, CenterState or the holders of any of the following securities, at the Effective Time:

(a)Each share of common stock, par value $0.01 per share, of CenterState (“CenterState Common Stock”) issued and outstanding immediately prior to the Effective Time shall continue to be one validly issued, fully paid and nonassessable share of common stock, par value $0.01, of the Surviving Company.

(b)Subject to Sections 1.4(c), 1.4(d), 1.4(e), 1.4(f), 8.1(viii), and 8.1(ix), each share of the common stock, par value $5.00 per share, of PBHC (the “PBHC Common Stock”) issued and outstanding immediately prior to the Effective Time, including Trust Account Common Shares and DPC Common Shares, but excluding any Cancelled Shares and any Dissenting Shares (collectively, the “Exchangeable Shares,” and each an “Exchangeable Share”), shall be converted, in accordance with the procedures set forth in Article II, into the right to receive (i) 3.7832 shares of CenterState Common Stock (the “Per Share Stock Consideration”), and (ii) a cash amount equal to $7.60 plus any cash dividends payable with respect to shares of the CenterState Common Stock that are payable to CenterState shareholders of record as of any date on or after the Closing Date, regardless of the issuance of certificates for shares of CenterState Common Stock to the former holders of the Exchangeable Shares, and any cash in lieu of fractional shares as specified in Section 2.2(g) (collectively, the “Per Share Cash Consideration” and, together with the Per Share Stock Consideration, the “Merger Consideration”).

(c)All shares of PBHC Common Stock that are owned by PBHC or CenterState (other than (i) shares of PBHC Common Stock held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties (any such shares, “Trust Account Common Shares”) and (ii) shares of PBHC Common Stock held, directly or indirectly, by PBHC or CenterState in respect of a debt previously contracted (any such shares, “DPC Common Shares”)) shall be cancelled and shall cease to exist (any such shares, the “Cancelled Shares”), and no consideration shall be delivered in exchange therefor.

(d)Notwithstanding anything in this Agreement to the contrary, shares of PBHC Common Stock that are issued and outstanding immediately prior to the Effective Time and which 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 Sections 607.1301 to 607.1333 of the FBCA (the “Dissenting Shares”), shall not be converted into or be exchangeable for the right to receive the Merger Consideration, but instead the holder of such Dissenting Shares shall be entitled to payment of the fair value of such shares in accordance with the provisions of Sections 607.1301 to 607.1333 of the FBCA (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist), unless and until such holder 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 PBHC Common Stock under such provisions of the FBCA. If any shareholder

dissenting pursuant to Sections 607.1301 to 607.1333 of the FBCA and this Section 1.4(d) shall have failed to perfect or shall have effectively withdrawn or lost such right, such holder’s shares of PBHC Common Stock shall thereupon be treated as if they had been converted into and become Exchangeable Shares as of the Effective Time, eligible to receive the Merger Consideration in accordance with Section 1.4(b), without any interest thereon. PBHC shall give CenterState (i) prompt notice of any written notices to exercise dissenters’ rights in respect of any shares of PBHC Common Stock, attempted withdrawals of such notices and any other instruments served pursuant to the FBCA and received by PBHC relating to dissenters’ rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under the FBCA. PBHC shall not, except with the prior written consent of CenterState, 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 Article II to pay for shares of PBHC Common Stock for which dissenters’ rights have been perfected shall be returned to CenterState upon demand.

(e)If the number of shares of CenterState Common Stock or PBHC Common Stock issued and outstanding prior to the Effective Time shall be increased or decreased as a result of a stock split, stock combination, stock dividend, recapitalization or similar transaction, with respect to such stock, and the record date therefor shall be prior to the Effective Time, the Merger Consideration shall be proportionately adjusted as necessary to preserve the relative economic benefit to the Parties.

(f)All of the Exchangeable Shares of PBHC Common Stock converted into the right to receive the Merger Consideration pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate previously representing any such shares of PBHC Common Stock (each, a “Certificate”) shall thereafter represent only the right to receive the Merger Consideration into which the shares of PBHC Common Stock represented by such Certificate have been converted pursuant to this Section 1.4.

1.5Stock Options. Each valid option to purchase shares of PBHC Common Stock (each, a “PBHC Stock Option”), outstanding and unexercised immediately prior to the Effective Time shall, by virtue of the Merger, automatically and without any action on the part of the holder thereof, become fully vested and be converted into the right to receive an amount of cash equal to the product of (i) the number or shares of PBHC Common Stock subject to such PBHC Stock Option, and (ii) the excess, if any, of (x) $76.00, over (y) the exercise price per share provided for such PBHC Stock Option (the “Option Exchange Payment”); provided, however, that in the event that the Merger Consideration is modified as a result of the application of Section 1.4(e), then the Option Exchange Payment shall be appropriately adjusted in order to reflect the impact of such modification to the Merger Consideration. As a condition to receiving the Option Exchange Payment, each holder of a PBHC Stock Option receiving an Option Exchange Payment shall deliver to CenterState an acknowledgment in writing, in a form reasonably acceptable to CenterState, that (i) such payment is in full satisfaction of such holder’s rights under such PBHC Stock Options, or (ii) each holder of PBHC Stock Options whose options are not entitled to any payment based upon the foregoing, that such PBHC Stock Options are terminated and of no further force or effect.

1.6Incorporation Documents and Bylaws of the Surviving Company. At the Effective Time, the articles of incorporation of CenterState in effect immediately prior to the Effective Time shall be the articles of incorporation of the Surviving Company until thereafter amended in accordance with applicable law. The bylaws of CenterState in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Company until thereafter amended in accordance with applicable law and the terms of such bylaws.

1.7Directors and Officers. The directors of the Surviving Company immediately following the Effective Time shall consist of the directors of CenterState immediately prior to the Effective Time, and such directors shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal. The officers of the Surviving Company immediately following the Effective Time shall consist of the officers of the CenterState immediately prior to the Effective Time, and such officers shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

1.8The Bank Merger. Except as provided below, after the Effective Time and at or after the close of business on the Closing Date, Platinum Bank (“Bank”), a Florida state-charted bank and wholly owned first-tier subsidiary of PBHC, shall be merged (the “Bank Merger”) with and into CenterState Bank of Florida, N.A., a national banking association and wholly owned first-tier subsidiary of CenterState (“CenterState Bank, N.A.”), in accordance with the provisions of applicable federal and state banking laws and regulations, and CenterState Bank, N.A. shall be the surviving bank (the “Surviving Bank”). PBHC and the Bank are collectively referred to as the “PBHC Entities”. The Bank Merger shall have the effects as set forth under applicable federal and state banking laws and regulations, and the Boards of Directors of the Parties shall cause the Boards of Directors of the Bank and CenterState Bank of Florida, N.A., respectively, to approve a separate merger agreement (the “Bank Merger Agreement”) in substantially the form attached hereto as Exhibit B, and cause the Bank Merger Agreement to be executed and delivered as soon as practicable following the date of execution of this Agreement. Each of CenterState and PBHC also shall approve the Bank Merger Agreement in their capacities as sole shareholders of CenterState Bank, N.A. and the Bank, respectively. The directors of the Surviving Bank immediately following the Effective Time shall consist of the directors of CenterState Bank, N.A. immediately prior to the Effective Time, and such directors shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal. The officers of the Surviving Bank immediately following the Effective Time shall consist of the officers of CenterState Bank, N.A. immediately prior to the Effective Time, plus such officers of the Bank hired by CenterState, N.A. in the Bank Merger, and such officers shall hold office until their respective successors are duly elected and qualified or their earlier death, resignation or removal. As provided in the Bank Merger Agreement, the Bank Merger may be abandoned at the election of CenterState Bank, N.A. at any time, whether before or after filings are made for regulatory approval of the Bank Merger, but if the Bank Merger is abandoned for any reason, the Bank shall continue to operate under the their respective names (together with any appendix required of national banking associations if its charter should be converted to that of a national bank).

2.1Exchange Agent. Prior to the Effective Time, CenterState shall appoint its transfer agent, Continental Stock Transfer and Trust Company, pursuant to an agreement (the “Exchange Agent Agreement”) to act as exchange agent (the “Exchange Agent”) hereunder.

(a) At or before the Effective Time, CenterState shall deposit, or shall cause to be deposited, with the Exchange Agent stock certificates representing the number of shares of CenterState Common Stock and cash sufficient to deliver the aggregate Merger Consideration payable under the terms hereof (together with, to the extent then determinable, any cash payable in lieu of shares of CenterState Common Stock as set forth in ‎‎Section 2.2(g) in accordance with this ‎Article II), and CenterState shall instruct the Exchange Agent to timely pay such consideration in accordance with this Agreement.

(b)Promptly after the Effective Time, but in no event later than five (5) Business Days after the Closing Date, the Exchange Agent shall mail to each holder of record of a Certificate which immediately prior to the Effective Time represented outstanding shares of PBHC Common Stock whose shares were converted into the right to receive the Merger Consideration pursuant to Section 1.4(b), including any cash in lieu of fractional shares of CenterState Common Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to each Certificate shall pass, only upon delivery of such Certificate (or affidavits of loss in lieu of such Certificate)) to the Exchange Agent and which shall be substantially in such form and have such other provisions as shall be prescribed by the Exchange Agent Agreement (the “Letter of Transmittal”) and (ii) instructions for use in surrendering a Certificate in exchange for the Merger Consideration to be issued or paid in consideration therefor.

(c)Upon surrender to the Exchange Agent of its Certificate or Certificates, accompanied by a properly completed Letter of Transmittal, a holder of PBHC Common Stock will be entitled to receive promptly after the Effective Time the Merger Consideration, including any dividends that are payable to CenterState shareholders of record as of any date on or after the Closing Date and cash in lieu of fractional shares of CenterState Common Stock to be issued or paid in consideration therefor in respect of the shares of PBHC Common Stock represented by its Certificate or Certificates. Until so surrendered, each such Certificate shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Merger Consideration, including any cash in lieu of fractional shares of CenterState Common Stock to be issued or paid in consideration therefor upon surrender of such Certificate and any dividends or distributions to which such holder is entitled pursuant to Section 1.4(b), in accordance with the provisions of this Article II.

(d)Notwithstanding the provisions of Section 1.4(b), no dividends or other distributions with respect to CenterState Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of CenterState Common Stock represented

thereby, in each case unless and until the surrender of such Certificate in accordance with this Article II. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the whole shares of CenterState Common Stock represented by such Certificate and not paid or (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of CenterState Common Stock represented by such Certificate with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the CenterState Common Stock issuable with respect to such Certificate or Book-Entry Shares.

(e)In the event of a transfer of ownership of a Certificate representing PBHC Common Stock that is not registered in the stock transfer records of PBHC, the shares of CenterState Common Stock and cash in lieu of fractional shares of CenterState Common Stock comprising the Merger Consideration shall be issued or paid 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 PBHC 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 CenterState that the tax has been paid or is not applicable. The Exchange Agent (or, subsequent to the earlier of (x) the one-year anniversary of the Effective Time and (y) the expiration or termination of the Exchange Agent Agreement, CenterState) shall be entitled to deduct and withhold from any cash consideration or cash in lieu of fractional shares of CenterState Common Stock otherwise payable pursuant to this Agreement to any holder of PBHC Common Stock such amounts as the Exchange Agent or CenterState, as the case may be, is required to deduct and withhold under the Internal Revenue Code of 1986, as amended (the “Code”), or any provision of state, local or foreign tax law, with respect to the making of such payment. To the extent the amounts are so withheld by the Exchange Agent or CenterState, as the case may be, and timely paid over to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of PBHC Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or CenterState, as the case may be.

(f)After the Effective Time, there shall be no transfers on the stock transfer books of PBHC of the shares of PBHC Common Stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of PBHC Common Stock that occurred prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the Merger Consideration and any cash in lieu of fractional shares of CenterState Common Stock to be issued or paid in consideration therefor in accordance with the procedures set forth in this Article II.

(g)Notwithstanding anything to the contrary contained in this Agreement, no fractional shares of CenterState Common Stock shall be issued or upon the surrender of Certificates for exchange, no dividend or distribution with respect to CenterState Common Stock

shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of CenterState. In lieu of the issuance of any such fractional share, CenterState shall pay to each former shareholder of PBHC who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest whole cent) determined by multiplying (i) the Average Closing Stock Price by (ii) the fraction of a share (after taking into account all shares of PBHC Common Stock held by such holder at the Effective Time and rounded to the nearest one thousandth when expressed in decimal form) of CenterState Common Stock to which such holder would otherwise be entitled to receive pursuant to Section 1.4.

(h)In the event any Certificate shall have been lost, stolen, mutilated or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen, mutilated or destroyed and, if reasonably required by CenterState or the Exchange Agent, the posting by such Person of a bond in such amount as CenterState may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen, mutilated or destroyed Certificate the Merger Consideration deliverable in respect thereof pursuant to this Agreement.

3.1Representations and Warranties of PBHC. Except as Previously Disclosed, PBHC hereby represents and warrants to CenterState as follows (and, for purposes of this Section 3.1, the term “Company” shall mean PBHC and the Bank):

No Subsidiary of PBHC has issued or is bound by any Rights calling for the purchase or issuance of any shares of capital stock or any other equity security of such Subsidiary or any securities representing the right to purchase or otherwise receive any shares of capital stock or any other equity security of such Subsidiary.

(d)All information and materials provided pursuant to this Agreement shall be subject to the provisions of the Confidentiality Agreement entered into between the Parties as of April 21, 2016 (the “Confidentiality Agreement”).

(e)PBHC shall deliver to the Chief Executive Office of CenterState to the extent not otherwise precluded by applicable Law and excluding any materials related to the transactions contemplated by this Agreement or any other Acquisition Proposal or subject to any attorney-client privilege, all materials, reports and information provided to the Boards of Directors and all committees thereof of PBHC and Platinum Bank simultaneously with their submission to such directors and committee members.

(f)No investigation by a Party or its representatives shall affect the representations and warranties of the other Party set forth in this Agreement.

6.3Shareholder Meeting. PBHC shall, and shall cause its Board of Directors to, (i) take all action in accordance with the federal securities laws, the FBCA and the PBHC Charter and the PBHC Bylaws necessary to (A) call and give notice of a special meeting of PBHC’s shareholders (the “PBHC Shareholder Meeting”) for the purpose of seeking the PBHC Shareholder Approval within ten (10) Business Days following the date the Form S-4 is declared effective under the Securities Act (the “PBHC Shareholder Meeting Notice Date”) and (B) schedule the PBHC Shareholder Meeting to take place on a date that is within forty (40) days after the PBHC Shareholder Meeting Notice Date; (ii) use its commercially reasonable efforts to cause the PBHC Shareholder Meeting to be convened and held on the scheduled date; and (iii) subject to Section 6.7, use its commercially reasonable efforts to obtain the PBHC Shareholder Approval and include in the Proxy Statement the recommendation that the shareholders of PBHC approve this Agreement (the “PBHC Board Recommendation”). Notwithstanding anything to the contrary contained in this Agreement, PBHC shall not be required to hold the PBHC Shareholder Meeting if this Agreement is terminated pursuant to Section 6.7 or Section 8.1 prior to the scheduled time of the PBHC Shareholder Meeting.

6.4Nasdaq Listing. CenterState shall use its commercially reasonable efforts to cause the shares of CenterState Common Stock to be issued to the holders of PBHC Common Stock in the Merger to be authorized for listing on the Nasdaq, subject to official notice of issuance, prior to the Effective Time.

(a)Following the Effective Time, CenterState shall maintain or cause to be maintained employee benefit plans and compensation opportunities for the benefit of employees who are full-time active employees of PBHC and 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 CenterState 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 CenterState or its Subsidiaries. CenterState shall give the Covered Employees full credit for their prior service with PBHC 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 CenterState 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 CenterState.

(b)With respect to any employee benefit plan of CenterState 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, CenterState or its applicable Subsidiary shall use its commercially reasonable efforts to (i) cause any pre-existing condition limitations or eligibility waiting periods under such CenterState 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 PBHC 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 deductibles and annual out-of-pocket expense requirements under any such health, dental, vision or other welfare plan.

(c)Prior to the Effective Time, PBHC shall take, and shall cause its Subsidiaries to take, all actions requested by CenterState that may be necessary or appropriate to (i) cause one or more PBHC 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 PBHC 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 PBHC Benefit Plan for such period as may be requested by CenterState, or (iv) facilitate the merger of any PBHC Benefit Plan into any employee benefit plan maintained by CenterState or an CenterState Subsidiary. All resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this Section 6.5(c) shall be subject to CenterState’s reasonable prior review and approval, which shall not be unreasonably withheld, conditioned or delayed.

(d)Nothing in this Section 6.5 shall be construed to limit the right of CenterState or any of its Subsidiaries (including, following the Closing Date, PBHC and its Subsidiaries) to amend or terminate any PBHC 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 6.5 be construed to require CenterState or any of its Subsidiaries (including, following the Closing Date, PBHC and its Subsidiaries) to retain the employment of any particular Covered Employee for any fixed period of time following the Closing Date, and, except as otherwise provided pursuant to Section 7.2(e), the continued retention (or termination) by CenterState or any of its Subsidiaries of any Covered Employee subsequent to the Effective Time shall be subject in all events to CenterState’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)For purposes of this Agreement, “PBHC Benefit Plans” means any “employee benefit plan,” as defined in Section 3(3) of ERISA, and all other benefit plans, arrangements or agreements, including any other employment, consulting, bonus, incentive or deferred compensation, vacation, stock option or other equity-based, severance, termination, retention, change of control, profit-sharing, fringe benefit or other similar plan, program, agreement or commitment, whether written or unwritten, whether or not subject to ERISA, or whether formal or informal, for the benefit of any employee, former employee, director or former director of PBHC or any of its Subsidiaries entered into, maintained or contributed to by PBHC or any of its Subsidiaries or to which PBHC or any of its Subsidiaries is obligated to contribute, or with respect to which PBHC or any of its Subsidiaries has any liability, direct or indirect, contingent or otherwise (including any liability arising out of an indemnification, guarantee, hold harmless or similar agreement) or otherwise providing benefits to any current, former or future employee, officer or director of PBHC or any of its Subsidiaries or to any beneficiary or dependent thereof.

(f)If, within six (6) months after the Effective Time, any Covered Employee is terminated by CenterState or its Subsidiaries other than “for cause” or as a result of unsatisfactory job performance, then CenterState shall pay severance to such Covered Employee in an amount equal to two weeks of base salary for each twelve months of such Covered Employee’s prior employment with PBHC or the Bank; provided, however, that in no event will the total amount of severance for any single Covered Employee be less than four weeks of such base salary nor greater than twenty-six weeks of such base salary. 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 of CenterState and its Subsidiaries as then in effect.

(g)At or immediately before the Effective Time, PBHC shall cause the Paid Time Off (PTO) program of the Bank (which includes sick time and vacation time) (the “Program”) to be terminated with the following effects: (i) until the Effective Time, the Bank shall continue to pay benefits in accordance with the terms of the Program; (ii) at the Effective Time, all accrued and unused PTO for all employees of PBHC and its Subsidiaries, including awarded, unused PTO in the Excess PTO Bank and in the Catastrophic Leave Bank, shall be eliminated; and (iii) no PTO shall be carried over to CenterState or its Subsidiaries. Notwithstanding the foregoing, employees of PBHC and its Subsidiaries who, at the Effective Time are receiving PTO benefits from the Excess PTO Bank due to personal or family extended illness or Catastrophic Leave (in either case, as awarded in accordance with the terms of the Program) shall receive a lump sum benefit equal to the amount of the remaining benefits previously awarded, and all other employees of PBHC and its Subsidiaries shall receive a lump sum benefit from earned, awarded and unused PTO in an amount equal to that which otherwise would have been paid upon termination of employment in accordance with the terms of the Program. Section 6.5(g) of the PBHC Disclosure Schedule sets forth the accrued and unused sick and vacation time for all employees as of the end of the calendar month immediately prior to the date of this Agreement. Also at the Effective Time, PBHC and its Subsidiaries shall pay to its employees the amounts set forth on Section 6.5(g) of the PBHC Disclosure Schedule.

(a)For a period of six (6) years from and after the Effective Time, CenterState shall indemnify, defend and hold harmless the present and former directors, officers and employees of PBHC and its Subsidiaries (the “Indemnified Parties”) against all costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages, settlements or liabilities as incurred 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 PBHC occurring at or before the Effective Time (including the transactions contemplated hereby), to the greatest extent as such persons are indemnified or have the right to advancement of expenses pursuant to (i) the PBHC Charter, the PBHC Bylaws or the articles or certificate of incorporation or formation and bylaws (or comparable organizational documents) of PBHC’s Subsidiaries, each as in effect on the date of this Agreement, and (ii) the FBCA.

(b)Any Indemnified Party wishing to claim indemnification under this Section 6.6 shall promptly notify CenterState upon learning of any Claim, provided that failure to so notify shall not affect the obligation of CenterState under this Section 6.6 unless, and only

to the extent that, CenterState is actually and materially prejudiced in the defense of such Claim as a consequence. In the event of any such Claim (whether arising before or after the Effective Time), (i) CenterState shall have the right to assume the defense thereof and CenterState shall not be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, unless such Indemnified Party is advised in writing by counsel that the defense of such Indemnified Party by CenterState would create an actual or potential conflict of interest (in which case, CenterState shall not be obligated to reimburse or indemnify any Indemnified Party for the expenses of more than one such separate counsel for all Indemnified Parties, in addition to one local counsel in the jurisdiction where defense of any Claim has been or is to be asserted), (ii) the Indemnified Parties will cooperate in the defense of any such matter, (iii) CenterState shall not be liable for any settlement effected without its prior written consent and CenterState shall not settle any Claim without such Indemnified Party’s prior written consent (which consent shall not be unreasonably withheld or delayed), and (iv) CenterState shall have no obligation hereunder 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.

(c)For a period of six (6) years following the Effective Time, CenterState will use its commercially reasonable efforts to provide director’s and officer’s liability insurance (“D&O Insurance”) that serves to reimburse the present and former officers and directors of PBHC 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 the coverage currently provided by PBHC; provided, however, that (i) if CenterState is unable to maintain or obtain the insurance called for by this Section 6.6(c), then CenterState will provide as much comparable insurance as is reasonably available, (ii) officers and directors of PBHC 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, and (iii) in satisfaction of its obligations under this Section 6.6(c), CenterState may require PBHC to purchase, prior to but effective as of the Effective Time, tail insurance providing such coverage prior to Closing. Whether or not CenterState or PBHC shall procure such coverage, in no event shall PBHC expend, or CenterState be required to expend, for such tail insurance a premium amount in excess of an amount equal to 200% of the annual premiums paid by PBHC 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, then PBHC or CenterState, as applicable, 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.

(d)If CenterState 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 CenterState and its Subsidiaries shall assume the obligations set forth in this Section 6.6.

(e)These rights shall survive consummation of the Merger and are intended to benefit, and shall be enforceable by, each Indemnified Party. After the Effective Time, the obligations of CenterState under this ‎Section 6.6 shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party unless the affected Indemnified Party shall have consented in writing to such termination or modification. If any Indemnified Party makes any claim for indemnification or advancement of expenses under this ‎Section 6.6 that is denied by CenterState, and a court of competent jurisdiction determines that the Indemnified Party is entitled to such indemnification or advancement of expense, then CenterState or the Surviving Entity shall pay such Indemnified Party’s costs and expenses, including legal fees and expenses, incurred in connection with enforcing such claim against CenterState. If any Indemnified Party makes any claim for indemnification or advancement of expenses under the Section 6.6 that is denied by CenterState, and a court of competent jurisdiction determines that the Indemnified Party is not entitled to such indemnification or advancement of expense, the Indemnified Party shall pay CenterState’s or the Surviving Entity’s costs and expenses, including legal fees and expenses, incurred in connection with defending such claim against the Indemnified Party.

(f)Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to Company or any of its Subsidiaries for any of their respective directors, officers or other employees, it being understood and agreed that the indemnification provided for in this ‎‎Section 6.6 is not prior to or in substitution for any such claims under such policies.

(a)PBHC agrees that, except as expressly permitted by Section 6.7(b), from the date of this Agreement until the Effective Time or, if earlier, the termination of this Agreement in accordance with Section 8.1, it will not, and will cause its Subsidiaries and its Subsidiaries’ officers, directors, and employees (the “PBHC Individuals”) not to, and will use its commercially reasonable efforts to cause PBHC and its Subsidiaries’ agents, advisors, accountants, legal counsel, and financial advisors (the “PBHC Representatives”) not to, initiate, solicit, encourage or knowingly facilitate inquiries or proposals with respect to, or engage in any discussions or negotiations concerning, or provide any confidential or nonpublic information or data concerning its and its Subsidiaries’ business, properties or assets (“PBHC Confidential Information”) to, or have any discussions with, any Person relating to, any Acquisition Proposal. PBHC 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 CenterState with respect to any Acquisition Proposal and will use its commercially reasonable efforts, subject to applicable law, to enforce any confidentiality or similar agreement relating to such an Acquisition Proposal. It is understood that any breach of the provisions of this Section 6.7 by any PBHC Representative shall constitute a breach by PBHC.

(b)Notwithstanding anything to the contrary in Section 6.7(a), at any time from the date of this Agreement and prior to obtaining the PBHC Shareholder Approval, in the event PBHC receives an unsolicited Acquisition Proposal and the Board of Directors of PBHC determines in good faith that there is a reasonable likelihood that such Acquisition Proposal constitutes, or is reasonably likely to result in, a Superior Proposal, PBHC may, and may permit its Subsidiaries and the PBHC Individuals and the PBHC Representatives to, (i) negotiate the

terms of, and enter into, a confidentiality agreement with terms and conditions no less favorable to PBHC than the Confidentiality Agreement, (ii) furnish or cause to be furnished PBHC Confidential Information to the Person or Persons making such Acquisition Proposal pursuant to such confidentiality agreement, and (iii) negotiate and participate in such negotiations or discussions with the Person or Persons making such Acquisition Proposal concerning such Acquisition Proposal, if the Board of Directors of PBHC determines in good faith (following consultation with counsel) that failure to take such actions would or would be reasonably likely to result in a violation of its fiduciary duties under applicable law.

(c)The Board of Directors of PBHC shall not (nor shall any committee thereof) withdraw or modify, in a manner adverse to CenterState, the PBHC Board Recommendation or make or cause to be made any third party or public communication proposing or announcing an intention to withdraw or modify in any manner adverse to CenterState the PBHC Board Recommendation (any such action, a “Change in Recommendation”). Notwithstanding the foregoing, if the PBHC Board concludes in good faith (after consultation with its outside legal and financial advisors) that an Acquisition Proposal constitutes a Superior Proposal and (after consultation with its legal advisors) that failure to do so could be inconsistent with its fiduciary obligations to the stockholders of PBHC under applicable Laws, the PBHC Board may at any time prior to the PBHC Shareholder Approval (i) effect a Change of Recommendation or (ii) terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal; provided, however, that the Board of Directors of PBHC may not make a Change in Recommendation, or terminate this Agreement, with respect to an Acquisition Proposal unless (i) PBHC shall not have breached this Section 6.7 in any respect and (ii) (A) the Board of Directors of PBHC determines in good faith (after consultation with counsel) that such Superior Proposal has been made and has not been withdrawn and continues to be a Superior Proposal after taking into account all adjustments to the terms of this Agreement that may be offered by CenterState under this Section 6.7(c); (B) PBHC has given CenterState at least three (3) days’ prior written notice of its intention to take such action 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, PBHC has negotiated, and has caused its representatives to negotiate, in good faith with CenterState during such notice period to the extent CenterState wishes to negotiate, to enable CenterState 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, PBHC shall, in each case, be required to deliver to CenterState a new written notice, the notice period shall have recommenced and PBHC shall be required to comply with its obligations under this Section 6.7 with respect to such new written notice.

(d)PBHC will advise CenterState in writing within twenty-four (24) hours following receipt of any Acquisition Proposal and the substance thereof (including the identity of the Person making such Acquisition Proposal), and will keep CenterState apprised of any related developments, discussions and negotiations (including the terms and conditions of the Acquisition Proposal) on a current basis.

(e)As used in this Agreement, the following terms have the meanings set forth below:

“Acquisition Proposal” means a tender or exchange offer, proposal for a merger, consolidation or other business combination involving PBHC or any of its Significant Subsidiaries or any proposal or offer to acquire in any manner in a single transaction or series of transactions more than fifty percent (50%) of the voting power in, or more than twenty percent (20%) of the fair market value of the business, assets or deposits of, PBHC or any of its Significant Subsidiaries, other than the transactions contemplated by this Agreement.

“Superior Proposal” means a written Acquisition Proposal that the Board of Directors of PBHC concludes in good faith to be more favorable from a financial point of view to its shareholders than the Merger and the other transactions contemplated hereby, (i) after receiving the advice of its financial advisors (who shall be a nationally recognized investment banking firm, CenterState acknowledging that Hovde Group is a nationally recognized investment banking firm), (ii) after taking into account the likelihood of consummation of such transaction on the terms set forth therein and (iii) after taking into account all legal (with the advice of outside counsel), financial (including the financing terms of any such proposal), regulatory and other aspects of such proposal and any other relevant factors permitted under applicable law; provided, however, that for purposes of the definition of “Superior Proposal,” the references to twenty percent (20%) in the definition of Acquisition Proposal shall be deemed to be references to fifty percent (50%).

6.8Notification of Certain Matters. Each of the Parties shall give prompt written notice to the other of any fact, event or circumstance known to it that (a) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (b) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein. Each of the Parties shall promptly inform the other in writing upon receiving notice of any material Action by any Governmental Entity or third party against, or threatened against, it or any of its Subsidiaries or any of their respective assets, properties, or any of their respective directors, officers or employees in their individual capacities as such.

6.9Correction of Information. Each of PBHC and CenterState shall promptly correct and supplement in writing any information set forth in the Schedules to this Agreement furnished under this Agreement so that such schedules shall be correct and complete in all material respects at all times, without taking into account any Material Adverse Effect qualification contained in Article VII, and shall include all facts necessary to make such information correct and complete in all material respects at all times; provided, however, that in each case, such disclosure shall not be deemed to cure any breach of a representation, warranty, covenant or agreement or any failure of a condition under Article VII, or to otherwise limit or affect in any way the remedies available hereunder to any Party receiving such notice.

6.10System Integration. From and after the date hereof, PBHC shall cause the Bank and its directors, officers and employees to, and shall make all commercially reasonable efforts (without undue disruption to either business) to cause the Bank’s data processing consultants and software providers to, cooperate and assist the Bank and CenterState Bank of Florida, N.A. in connection with an electronic and systematic conversion of all applicable data of the Bank to the

CenterState system following the Effective Time, including the training of the Bank employees without undue disruption to the Bank’s business, during normal business hours and at the expense of CenterState (not to include the Bank’s standard employee payroll).

6.11Coordination; Integration. Subject to applicable law and regulation, during the period from the date hereof until the Effective Time, PBHC shall cause the Chief Executive Officer of the Bank or his designee to assist and confer with the officers of CenterState Bank of Florida, N.A., on a weekly basis, relating to the development, coordination and implementation of the post-Merger operating and integration plans of CenterState Bank of Florida, N.A., as the resulting institution in the Bank Merger.

6.12Non-Competition and Non-Disclosure Agreement. Concurrently with the execution and delivery of this Agreement and effective upon Closing, PBHC has caused each director of PBHC and the Bank (other than Kenneth Ely) to execute and deliver the Non-Competition and Non-Disclosure Agreement in the form attached hereto as Exhibit C (collectively, the “Director Restrictive Covenant Agreements”).

6.13Claims Letters. Concurrently with the execution and delivery of this Agreement and effective upon the Closing, PBHC has caused each director of PBHC and the Bank to execute and deliver the Claims Letter in the form attached hereto as Exhibit D.

6.14Tax Treatment. Each of the Parties undertakes and agrees to use reasonable efforts to cause the Merger, and to use commercially reasonable efforts to take no action which would cause the Merger not, to qualify as a “Reorganization” within the meaning of Section 368(a) of the Code for federal income tax purposes.

(a)Tax Returns. The PBHC Shareholder Representative, at its sole cost and expense, shall prepare and timely file, or cause to be prepared and timely filed, all income Tax Returns of PBHC and its Subsidiaries for any Taxable Period (or portion thereof) ending on or before the Closing Date (the “Pre-Closing Tax Period”), which are filed after the Closing Date. Such Tax Returns shall be prepared in a manner consistent with the prior practices of PBHC and each of its Subsidiaries unless otherwise required by applicable Law. Such Tax Returns shall be submitted by the PBHC Shareholder Representative to CenterState (together with applicable schedules and statements) at least 45 days prior to the due date (taking into account any extensions) of such Tax Return. If CenterState objects to any item on any such Tax Return, it shall, within 30 days after delivery of such Tax Return, notify the PBHC Shareholder Representative in writing that it so objects, specifying with particularity any such item and stating the specific factual or legal basis for any such objection. If a notice of objection shall be duly delivered, the parties shall cooperate in good faith and use their reasonable efforts to resolve such items. If CenterState and the PBHC Shareholder Representative are unable to reach an agreement within 10 days after receipt by the PBHC Shareholder Representative of such Notice of Objection, the disputed items shall be resolved by the Tax Referee, who shall resolve such dispute within 20 days and the Tax Return shall be filed to reflect the Tax Referee’s resolution, which shall be final, conclusive and binding on the parties. Each party shall be responsible for its respective fees and expenses associated with any dispute, and the costs associated with any Tax Referee shall be paid equally by CenterState, on the one hand, and the PBHC Shareholder

Representative, on the other hand (who may utilize the funds described in Section 6.15(f)) for such purpose. CenterState shall prepare and timely file, or cause to be prepared and timely filed, all non-income Tax Returns for the Pre-Closing Tax Period, which are filed after the Closing Date.

(b)Payment of Taxes.

Notwithstanding any other provision of this Agreement, CenterState shall have no obligation (as successor or otherwise) for any income Taxes attributable to the Pre-Closing Period.

(c)Cooperation. The Parties will provide each other with such cooperation and information as they may reasonably request of each other in preparing or filing any Tax Return, in determining a liability or right of refund, or in conducting any audit or other proceeding, in respect of Taxes attributable to the Pre-Closing Period. CenterState shall provide prompt written notice to the PBHC Shareholder Representative of any audit or examination of a Pre-Closing Tax Period that may give rise to a Tax liability for the PBHC shareholders. CenterState shall permit the PBHC Shareholder Representative to participate, at the expense of the PBHC Shareholder Representative, in such audit or examination and shall make available relevant documents in connection therewith. Prior to any settlement or compromise of any audit or examination of Pre-Closing Tax Period, the PBHC Shareholder Representative shall be permitted to provide written comments on the proposed settlement or compromise which CenterState shall reasonably consider in good faith. The PBHC Shareholder Representative shall have the right in its sole judgement to approve any settlement based upon the outcome of any audit or examination as long as any such settlement does not adversely affect CenterState or cause CenterState to incur any amounts for the Tax liability of the PBHC shareholders.

(d)Distribution for Taxes. PBHC will remain an S corporation under the Code until the Closing Date. PBHC will be permitted to make a distribution to its shareholders for the 2016 calendar tax year up to 40% of PBHC’s taxable income as reflected on its 2016 U.S. Income Tax Return for an S corporation (Form 1120S). No tax distribution will be made for the 2017 tax year.

(e)Section 338(h)(10) Election. CenterState shall not make an election with respect to PBHC pursuant to Section 338(h)(10) of the Code without the prior written consent of PBHC.

On the third anniversary of the Effective Time, the PBHC Shareholder Representative will return any unused portion of such fund to CenterState. The foregoing $50,000 fund shall be maintained in an account at CenterState Bank, N.A. and shall include a provision for the automatic transfer of the ownership of the remaining proceeds in such account to CenterState on the third anniversary of the Effective Time.

6.16Failure to Fulfill Conditions. In the event that either Party determines that a condition to its obligation to complete the Merger cannot be fulfilled and that it will not waive that condition, it will promptly notify the other Party.

6.173020 Azeele, Inc.. PBHC and the Bank shall use their commercially reasonable efforts to cause 3020 Azeele, Inc. to cause the sale of the real property that is the subject of the certain Lease Agreement With Option to Purchase dated April 25, 2001 between 3020 Azeele, Inc. and Lifepath Hospice and Palliative Care, Inc. (the “Azeele Agreement”) to be transferred to Lifepath Hospice and Palliative Care, Inc. as soon as practicable following the date of this Agreement subject to and in accordance with the terms of the Azeele Agreement or, if such transfer cannot be effected prior to the closing, then PBHC and the Bank shall use their commercially reasonable efforts to cause at least a majority of the outstanding equity securities of 3020 Azeele, Inc. to be transferred to PBHC for a nominal amount of consideration.

No Consent so obtained which is necessary to consummate the transactions provided for in this Agreement shall be conditioned or restricted in a manner which in the reasonable judgment of the Board of Directors of either Party would so materially adversely impact the economic or business benefits of the transactions contemplated by this Agreement as to render inadvisable the consummation of the Merger.

(ii)by either PBHC or CenterState, if any Governmental Entity that must grant a Requisite Regulatory Approval has denied approval of the Merger or the Bank

Merger and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final and nonappealable order, injunction or decree permanently enjoining or otherwise prohibiting or making illegal the consummation of the Merger or the Bank Merger;

(iii)by either PBHC or CenterState, if the Merger shall not have been consummated on or before 210 days following the date of this Agreement, unless the failure of the Closing to occur by such date shall be due to the failure of the Party seeking to terminate this Agreement to perform or observe the covenants and agreements of such Party set forth in this Agreement;

(iv)by either PBHC or CenterState (provided that the terminating Party is not then in material breach of any representation, warranty, covenant or other agreement contained herein), if there shall have been a breach of any of the covenants or agreements or any of the representations or warranties set forth in this Agreement on the part of PBHC, in the case of a termination by CenterState, or CenterState, in the case of a termination by PBHC, which breach, either individually or in the aggregate, would result in, if occurring or continuing on the Closing Date, the failure of the conditions set forth in Section 7.2(a) or 7.2(b) (in the case of a termination by CenterState) or 7.3(a) or Section 7.3(b) (in the case of a termination by PBHC), and which is not cured within twenty (20) days following written notice to the Party committing such breach or by its nature or timing cannot be cured within such time period;

(vii)by either PBHC or CenterState, if the provisions of Section 8.1(a)(v) are not applicable and the shareholders of PBHC fail to provide the PBHC Shareholder Approval at a duly held meeting of shareholders or at an adjournment or postponement thereof.

(viii)By the Board of Directors of PBHC, if the PBHC Board of Directors so determines at any time during the five (5) day period commencing prior to the Determination Date, if, and only if, both of the following conditions are satisfied:

(a)the number obtained by dividing the Average Closing Price by the Initial CenterState Market Price (the “CenterState Ratio”) is less than 0.825; and

(b)the CenterState Ratio is less than the number obtained by (1) dividing the Final Index Price by the Initial Index Price (the “Index Ratio”) and (2) subtracting 0.175 from such quotient,

Within five (5) Business Days following its receipt of such notice, CenterState shall have the option to increase the Per Share Cash Consideration to equal the lesser of:

(x)the product of the Average Closing Price and an amount equal to: (1) the quotient (rounded to the nearest one-ten-thousandth), the numerator of which is equal to the product of (A) the Per Share Stock Consideration (as then in effect) and (B) the Index Ratio minus 0.175, and the denominator of which is equal to the CenterState Ratio, less (2) the Per Share Stock Consideration (as then in effect), or

If CenterState so elects, it shall give written notice to PBHC of such election and the amount of increase in the per share Merger Consideration within the five (5) Business Day period following its receipt of notice of termination from PBHC, whereupon no termination shall have occurred pursuant to this Section 8.1(a)(viii) and this Agreement shall remain in full force and effect in accordance with its terms (except that the Per Share Cash Consideration and the corresponding total Merger Consideration shall have been so modified).

(ix)By the Board of Directors of CenterState, if the CenterState Board of Directors so determines at any time during the five (5) Business Day period commencing prior to the Determination Date, if, and only if, both of the following conditions are satisfied:

(b)the CenterState Ratio is greater than the number obtained by adding 0.175 to the Index Ratio,

If CenterState elects to exercise its rights under this Section 8.1(a)(ix), it shall give prompt written notice thereof to PBHC. Within five (5) Business Days following the delivery of such notice, PBHC shall have the option to accept a reduction in the Per Share Stock Consideration to equal the higher of:

(x)the quotient (rounded to the nearest one-ten-thousandth), the numerator of which is equal to the product of (x) the Per Share Stock Consideration (as then in effect) and (y) the Index Ratio plus 0.175, and the denominator of which is equal to the CenterState Ratio, or

(y)the quotient (rounded to the nearest one-ten-thousandth), the numerator of which is equal to the product of the Per Share Stock Consideration (as then in effect), the Initial CenterState Market Price and 1.175, and the denominator of which is the Average Closing Price.

If PBHC so elects, it shall give written notice to CenterState of such election to proceed with the Merger by accepting the reduction in the Per Share Stock Consideration within the five (5) Business Day period following its delivery of notice of termination to PBHC, whereupon no termination shall have occurred pursuant to this Section 8.1(a)(ix) and this Agreement shall remain in full force and effect in accordance with its terms (except that the Per Share Stock Consideration and the corresponding total Merger Consideration shall have been so modified).

Notwithstanding the foregoing, CenterState will not have the right to terminate this Agreement pursuant to this Section 8.1(ix) if there is an announcement of an Acquisition Proposal for CenterState or any of its Significant Subsidiaries between the date of this Agreement and the Determination Date and, following such announcement, the CenterState Ratio increases to an amount in excess of 1.175.

For purposes of the immediately preceding clauses (i) and (ii), the references to twenty percent (20%) in the definition of Acquisition Proposal shall be deemed to be references to fifty percent (50%).

(c)Notwithstanding anything to the contrary in this Agreement, other than in the case of a willful and material breach of this Agreement the payment of the PBHC Termination Fee pursuant to this Section 8.4 shall fully discharge PBHC from, and be the sole and exclusive remedy of the other Party with respect to, any and all losses that may be suffered by such other Party based upon, resulting from or arising out of the circumstances giving rise to such termination of this Agreement. In no event shall PBHC be required to pay the PBHC Termination Fee on more than one occasion.

Any agreement on the part of a Party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

IN WITNESS WHEREOF, CenterState and PBHC have caused this Agreement to be executed by their respective officers thereunto duly authorized as of the date first above written.

This Shareholder Voting Agreement (this “Agreement”) is entered into as of the 17^th day of October, 2016, by and between CenterState Banks, Inc., a Florida corporation (“CenterState”), and the undersigned holder (“Shareholder”) of Common Stock (as defined herein).

WHEREAS, as of the date hereof, Shareholder “beneficially owns” (as such term is defined in Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended) and is entitled to dispose of (or to direct the disposition of) and to vote (or to direct the voting of) the number of shares of voting common stock, $5.00 par value per share (the “Common Stock”), of Platinum Bank Holding Company (“PBHC”), indicated on the signature page of this Agreement under the heading “Total Number of Shares of Common Stock Subject to this Agreement” (such shares of Common Stock, together with any other shares of Common Stock which are acquired by Shareholder during the period from and including the date hereof through and including the date on which this Agreement is terminated in accordance with its terms, are collectively referred to herein as the “Shares”);

WHEREAS, CenterState and PBHC propose to enter into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”; for purposes of this Agreement, capitalized terms used and not otherwise defined herein shall have the respective meanings ascribed to them in the Merger Agreement), pursuant to which, among other things, PBHC will merge with and into CenterState (the “Merger”); and

WHEREAS, as a condition to the willingness of CenterState to enter into the Merger Agreement, Shareholder is executing this Agreement;

NOW, THEREFORE, in consideration of, and as a material inducement to, CenterState entering into the Merger Agreement and proceeding with the transactions contemplated thereby, and in consideration of the expenses incurred and to be incurred by CenterState in connection therewith, Shareholder and CenterState, intending to be legally bound, hereby agree as follows:

1.Agreement to Vote Shares. Shareholder agrees that, while this Agreement is in effect, at any meeting of Shareholders of PBHC, however called, or at any adjournment thereof, or in any other circumstances in which Shareholder is entitled to vote, consent or give any other approval, except as otherwise agreed to in writing in advance by CenterState, Shareholder shall:

(a)appear at each such meeting or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

(b)vote (or cause to be voted), in person or by proxy, all the Shares as to which Shareholder has, directly or indirectly, the right to vote or direct the voting, (i) in favor of adoption and approval of the Merger Agreement and the transactions contemplated thereby (including, without limitation, any amendments or modifications of the terms thereof adopted in accordance with the terms thereof); (ii) against any action or agreement that would result in a

breach of any covenant, representation or warranty or any other obligation or agreement of PBHC contained in the Merger Agreement or of Shareholder contained in this Agreement; and (iii) against any Acquisition Proposal or any other action, agreement or transaction that is intended, or could reasonably be expected, to impede, interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect consummation of the transactions contemplated by the Merger Agreement or this Agreement.

Shareholder further agrees not to vote or execute any written consent to rescind or amend in any manner any prior vote or written consent, as a shareholder of PBHC, to approve or adopt the Merger Agreement unless this Agreement shall have been terminated in accordance with its terms.

2.No Transfers. While this Agreement is in effect, Shareholder agrees not to, directly or indirectly, sell, transfer, pledge, assign or otherwise dispose of, or enter into any contract option, commitment or other arrangement or understanding with respect to the sale, transfer, pledge, assignment or other disposition of, any of the Shares; provided, however, that the following transfers shall be permitted: (a) transfers by will or operation of law, in which case this Agreement shall bind the transferee; (b) transfers pursuant to any pledge agreement, subject to the pledgee agreeing in writing, prior to such transfer, to be bound by the terms of this Agreement; (c) transfers in connection with estate and tax planning purposes, including transfers to relatives, trusts and charitable organizations, subject to each transferee agreeing in writing, prior to such transfer, to be bound by the terms of this Agreement; and (d) such transfers as CenterState may otherwise permit in its sole discretion. Any transfer or other disposition in violation of the terms of this Section 2 shall be null and void.

3.Representations and Warranties of Shareholder. Shareholder represents and warrants to and agrees with CenterState as follows:

(a)Shareholder has all requisite capacity and authority to enter into and perform his, her or its obligations under this Agreement.

(b)This Agreement has been duly executed and delivered by Shareholder, and assuming the due authorization, execution and delivery by CenterState, constitutes the valid and legally binding obligation of Shareholder enforceable against Shareholder in accordance with its terms, except as may be limited by bankruptcy, insolvency, fraudulent transfer, moratorium, reorganization or similar laws of general applicability relating to or affecting the rights of creditors generally and subject to general principles of equity.

(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, limited liability company, partnership, trust or other entity, any charter, bylaw or other organizational document of Shareholder.

(d)Shareholder is the beneficial owner of the Shares. Shareholder does not own, of record or beneficially, any shares of capital stock of PBHC other than the Shares or any other securities convertible into or exercisable or exchangeable for such capital stock, other than any PBHC Stock Options. 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. 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.

4.No Solicitation. From and after the date hereof until the termination of this Agreement pursuant to Section 7 hereof, Shareholder, in his, her or its capacity as a shareholder of PBHC, shall not, nor shall Shareholder in such capacity authorize any shareholder, member, partner, officer, director, advisor or representative of Shareholder or any of his, her or its affiliates to (and, to the extent applicable to Shareholder, such Shareholder shall use commercially reasonable efforts to not permit any of his, her or its representatives or affiliates to), (a) initiate, solicit, induce or knowingly encourage, or knowingly 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) participate in any discussions or negotiations regarding any Acquisition Proposal, or furnish, or otherwise afford access, to any person (other than CenterState) any information or data with respect to PBHC or otherwise relating to an Acquisition Proposal, (c) enter into any agreement, agreement in principle, letter of intent, memorandum of understanding or similar arrangement with respect to an Acquisition Proposal, (d) solicit proxies with respect to an Acquisition Proposal (other than the Merger and 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 terms of the Merger Agreement, or (e) initiate a shareholders’ vote or action by consent of PBHC’s shareholders with respect to an Acquisition Proposal. For avoidance of doubt, the parties acknowledge and agree that nothing in this Agreement shall limit or restrict Shareholder or any of his, her or its affiliates who is or becomes during the term hereof a member of the Board of Directors or an officer of PBHC or any of its Subsidiaries from acting, omitting to act or refraining from taking any action, solely in such person’s capacity as a member of the Board of Directors or as an officer of PBHC (or as an officer or director of any of its Subsidiaries) consistent with his or her fiduciary duties in such capacity under applicable law.

5.Irrevocable Proxy. Subject to the last sentence of this Section 5, by execution of this Agreement, Shareholder does hereby appoint CenterState with 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 the Shares, to vote each of such Shares that Shareholder shall be entitled to so vote with respect to the matters set forth in Section 1 hereof at any meeting of the shareholders of PBHC, and at any adjournment or postponement thereof, and in connection with any action of the shareholders of PBHC taken by written consent. Notwithstanding the foregoing, the holder of such proxy shall not exercise such proxy on any matter other than as set forth in Section 1. 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 7 hereof and hereby revokes any proxy previously granted by Shareholder with

respect to the Shares. Notwithstanding anything contained herein to the contrary, this irrevocable proxy shall automatically terminate upon the termination of this Agreement.

6.Specific Performance; Remedies; Attorneys’ Fees. Shareholder acknowledges that it is a condition to the willingness of CenterState 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 CenterState if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, CenterState 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 CenterState has an adequate remedy at law. In addition, CenterState shall have the right to inform any third party that CenterState 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 CenterState hereunder, and that participation by any such thirty party with Shareholder in activities in violation of Shareholder’s agreement with CenterState set forth in this Agreement may give rise to claims by CenterState against 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 Party against which such action or proceeding is brought, in addition to any other relief to which such prevailing Party may be entitled.

7.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 written consent of the parties hereto, and this Agreement shall be automatically terminated upon: (i) termination of the Merger Agreement, 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.

8.Entire Agreement; Amendments. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provision hereof may be modified or waived, except by an instrument in writing signed by each party hereto. No waiver of any provision hereof by either party shall be deemed a waiver of any other provision hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

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

10.Capacity as Shareholder. This Agreement shall apply to Shareholder solely in his, her or its capacity as a shareholder of PBHC, and it shall not apply in any manner to Shareholder in any capacity as a director, officer or employee of PBHC or in any other capacity.

11.Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of Florida, without regard to any applicable conflicts of law principles or any other principle that could require the application of the law of any other jurisdiction.

12.WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF THE PARTIES IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT. EACH OF THE PARTIES HERETO (A) CERTIFIES THAT NO REPRESENTATIVE 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 AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 12.

13.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 to demand fair value for his, her or its Shares in connection with the Merger, in each case, that Shareholder may have under applicable law. Shareholder further agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against CenterState, PBHC 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. From time to time prior to the termination of this Agreement, at CenterState’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.

14.Disclosure. Shareholder hereby permits CenterState to publish and disclose in the Proxy Statement and Form S-4 (including, without limitation, all related documents and schedules filed with the Securities and Exchange Commission) his, her or its identity and ownership of shares of Common Stock and the nature of Shareholder’s commitments, arrangements and understandings pursuant to this Agreement.

15.Counterparts. This Agreement may be executed in counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Executed counterparts may be delivered by facsimile or other electronic transmission.

This Agreement embodies the entire agreement and understanding of the Banks with respect to the transactions contemplated hereby, and supersedes all other prior commitments, arrangements or understandings, both oral and written, among the Banks with respect to the subject matter hereof.

The provisions of this Agreement are intended to be interpreted and construed in a manner so as to make such provisions valid, binding and enforceable.

IN WITNESS WHEREOF, the undersigned have signed this Plan of Merger and Merger Agreement effective as of the date and year first set forth above.

This Non-Competition and Non-Disclosure Agreement (the “Agreement”), is entered into as of the 17^th day of October, 2016, by and between CenterState Banks, Inc., a Florida corporation (“CenterState”), and ____________________, an individual resident of the State of Florida (“Director”).

WHEREAS, pursuant to that certain Agreement and Plan of Merger dated as of October 17, 2016 (the “Merger Agreement”) by and between CenterState and Platinum Bank Holding Company, a Florida corporation (“PBHC”), PBHC will merge with and into CenterState (the “Merger”), as a result of which Platinum Bank, a Florida state-chartered bank and wholly owned subsidiary of PBHC (the “Bank”), will merge with and into CenterState Bank of Florida, N.A., a national banking association and wholly owned subsidiary of CenterState (“CenterState Bank, N.A.”);

WHEREAS, Director is a shareholder of PBHC 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 PBHC Common Stock (as defined in the Merger Agreement) held by Director;

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

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

WHEREAS, it is a material prerequisite to the consummation of the Merger that certain directors of PBHC, including Director, enter into this Agreement;

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

(a)Director acknowledges that (i) CenterState 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 CenterState as follows:

(i)From and after the Effective Time, Director will not disclose or use any Confidential Information or Trade Secret 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 or court order. In the event that Director is required by law or court order to disclose any Confidential Information, Director will: (i) if and to the extent permitted by such law or court order provide CenterState with prompt notice of such requirement prior to the disclosure so that CenterState may waive the requirements of this Agreement or seek an appropriate protective order at CenterState’s sole expense; and (ii) 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 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.

(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 CenterState), on Director’s own behalf or in the service or on behalf of others, solicit or attempt to solicit any customer of CenterState, CenterState Bank, N.A., PBHC or the Bank (each a “Protected Party”), including actively sought prospective customers of any of the Bank as of the Effective Date, for the purpose of providing products or services that are Competitive (as hereinafter defined) with those offered or provided by any Protected Party.

(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 CenterState), 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.

(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, shall mean products or services that are the same as or similar to the products or services of any Protected Party.

(A)relating to the business of PBHC and its subsidiaries, including the 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 PBHC and/or the Bank;

(C)having value to PBHC and/or any of the Bank and, as a result of the consummation of the transactions contemplated by the Merger Agreement, CenterState; and

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 PBHC or CenterState, (y) has been independently developed and disclosed by others, or (z) has otherwise entered the public domain through lawful means.

(iii)“Restricted Territory” shall mean each County in Florida where CenterState Bank, N.A. and/or the Bank operate a banking office at the Effective Time and each County contiguous to each of such Counties.

(iv)“Trade Secret” shall mean 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 CenterState 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, CenterState 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.

2.Notices. Any notice, consent, demand, request or other communication given to a party hereto in connection with this Agreement shall be in writing and shall be deemed to have been given to such party (x) when delivered personally to such party or (y) provided that a written acknowledgment of receipt is obtained, five (5) days after being sent by prepaid certified or registered mail or two (2) days after being sent by a nationally recognized overnight courier, to the address (if any) specified below for such party (or to such other address as such party shall have specified by ten (10) days’ advance notice given in accordance with this Section 3) or (z) in the case of CenterState only, on the first business day after it is sent by facsimile to the facsimile number set forth below (or to such other facsimile number as shall have specified by ten (10) days’ advance notice given in accordance with this Section 2), with a confirmatory copy sent by certified or registered mail or by overnight courier in accordance with this Section 2.

3.Governing Law. The validity, interpretation and performance of this Agreement shall be governed by the laws of the State of Florida, without giving effect to the conflicts of laws principles thereof.

4.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 CenterState. 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.

5.Severability. The invalidity or unenforceability of any provisions of this Agreement shall not affect the validity or enforceability of any other provisions of this Agreement, which shall remain in full force and effect.

6.Counterparts. This Agreement may be executed (and delivered via facsimile or other electronic transmission) in one or more counterparts, each of which shall be deemed an original, and all of which together shall constitute one and the same Agreement.
